This Quarterly Report on Form10-Q (the "Quarterly Report") contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This includes, without limitation, statements regarding the financial position, business strategy and the plans and objectives of management for future operations. These statements constitute projections, forecasts and forward-looking statements, and are not guarantees of performance. We have based these forward-looking statements on our current expectations and projections about future events. Any statements that refer to projections, forecasts or other characterizations of future events or circumstances are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “outlook,” “believes,” “expects,” “potential,” “continues,” “may,” “will,” “should,” “could,” “seeks,” “approximately,” “predicts,” “intends,” “plans,” “estimates,” “anticipates” or the negative version of these words or other comparable words or phrases.

These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions about us that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by such forward-looking statements. Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this Quarterly Report.

We caution you that these forward-looking statements are subject to numerous risks and uncertainties, most of which are difficult to predict and many of which are beyond our control. Some factors that could cause actual results to differ include:

•our ability to raise financing in the future;

•our ability to service our indebtedness and to access additional delayed draws that may in the future become available to us;

•changes in applicable laws or regulations;

•our ability to retain or recruit, or changes required in, our officers, key employees or directors;

•our ability to successfully commercialize any product candidates that we successfully develop and that are approved by applicable regulatory authorities;

•our expectations for the timing and results of data from clinical trials and regulatory approval applications;

•our estimates regarding expenses, future revenue, capital requirements and needs for additional financing;

•our business, operations and financial performance including:

◦our history of operating losses and expectations of significant expenses and continuing losses for the foreseeable future;

◦our ability to execute our business strategy, including the growth potential of the markets for our products and our ability to serve those markets;

◦our ability to grow market share in our existing markets or any new markets we may enter;

◦our ability to develop and maintain our brand and reputation;

◦our ability to partner with other companies;

◦the size of the addressable markets for our product candidates;

◦our expectations regarding our ability to obtain and maintain intellectual property protection and not infringe on the rights of others;

◦our ability to manage our growth effectively;

◦our ability to maintain the listing of our securities in the Nasdaq Global Market, and the potential liquidity and trading of such securities;

◦the outcome of any legal proceedings that may be instituted against us; and

◦unfavorable conditions in our industry, the global economy or global supply chain, including financial and credit market fluctuations, international trade relations, pandemics, political turmoil, natural catastrophes, warfare and terrorist attacks.

Given these risks and uncertainties, you should not place undue reliance on these forward-looking statements. Should one or more of the risks or uncertainties described in this Quarterly Report occur, or should underlying

Notes to Condensed Consolidated Financial Statements

(in thousands, except share and per share data)

(Unaudited)

(1) Nature of Business

On August 10, 2023 (the "Closing Date"), TriSalus Life Sciences, Inc., a Delaware corporation (the “Company,” “TriSalus,” “we,” “us”), formerly known as MedTech Acquisition Corporation (“MTAC”), consummated the announced merger pursuant to the Agreement and Plan of Merger by and between MTAC Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of MTAC (“Merger Sub”) and TriSalus Operating Life Sciences, Inc. (formerly known as TriSalus Life Sciences, Inc.), a Delaware corporation (“Legacy TriSalus”), whereby Merger Sub merged with and into Legacy TriSalus with the separate corporate existence of Merger Sub ceasing (the “Merger” and, together with the other transactions contemplated by the Merger Agreement, the “Business Combination”) and TriSalus Life Sciences, Inc. becoming the surviving company. In connection with the consummation of the Merger, on August 10, 2023, Legacy TriSalus changed its name from TriSalus Life Sciences, Inc. to TriSalus Operating Life Sciences, Inc., and MTAC changed its name from MedTech Acquisition Corporation to TriSalus Life Sciences, Inc., the surviving company. As further described in Note (3) Business Combination, Legacy TriSalus was deemed to be the accounting acquirer and predecessor company in the Business Combination.

We are a growing, oncology focused medical technology business seeking to transform outcomes for patients with solid tumors by integrating our innovative delivery technology with standard-of-care therapies, and with our investigational immunotherapeutic, nelitolimod, a class C Toll-like receptor 9 (“TLR9”) agonist, for a range of different therapeutic and technology applications. Our ultimate goal is to transform the treatment paradigm for patients battling solid tumors. We have developed an innovative technology designed to overcome two significant challenges that prevent optimal delivery and performance of therapeutics in these difficult-to-treat diseases: (i) high intratumoral pressure caused by tumor growth and collapsed vasculature restricting the delivery of oncology therapeutics and (ii) off target delivery. Nelitolimod, specifically, combined with our technology, aims to address the immunosuppressive properties of tumor immune cells in liver, pancreas and other solid tumors. By systematically addressing these barriers, we aim to improve response to therapies and to enable improved patient outcomes.

We market our cutting-edge Pressure Enabled Drug Delivery (PEDD™) infusion systems, which optimize delivery of embolics and therapeutics for the treatment of various solid tumors. Our PEDD with SmartValve™ is the only technology designed to work in synchrony with the cardiac cycle to open collapsed arterial vessels to enable deeper perfusion and improve therapeutic drug delivery in tumors with high intratumoral pressure. In multiple preclinical models and certain prospective and retrospective clinical studies, PEDD with SmartValve has been shown to improve therapy uptake and tumor response. Additionally, we have conducted Phase I clinical trials of a novel product candidate, nelitolimod (a TLR9 agonist), which has the potential to enhance immune system response, when delivered via PEDD, in the treatment of locally-advance pancreatic adenocarcinoma (LA-PDAC) and primary and secondary liver tumors. The combination of our PEDD technology with nelitolimod is focused on solving the two main barriers in the tumor microenvironment that inhibit the success of systemic therapies. The first barrier (mechanical) is comprised of high intratumoral pressure within tumors that limits drug uptake and the second barrier (biological) is intratumoral immunosuppression. Nelitolimod has shown a dual mechanism of action in some solid tumors: the alteration of the tumor microenvironment by reducing immunosuppressive myeloid derived suppressor cells and simultaneous activation of immune response and recruiting T-cells to the tumor, which may allow checkpoint inhibitors to work more effectively.

TriNav™ is the newest therapy delivery device with SmartValve technology for the proprietary PEDD approach. Current sales consist of the TriNav Infusion System, introduced in 2020, and TriNav LV Infusion System, introduced in 2024. In 2020, we gained transitional pass-through payments (“TPT”) approval from the Centers for Medicare & Medicaid Services (“CMS”), which allows hospitals to cover the cost of using TriNav. The approval expired at the end of 2023. In 2023, we applied for a new technology Ambulatory Payment Classification ("APC") code with CMS and were granted a New Technology Healthcare Common Procedure Coding System ("HCPCS") code for both mapping and therapeutic procedures involving TriNav. This code, HCPCS C9797, has been assigned to the APC code 5194 - Level 4 Endovascular procedures. The code became effective on January 1, 2024, and may be reported by hospital outpatient departments and ambulatory surgical centers. Effective April 1, 2025, TriNav received a second unique and permanent HCPCS code from CMS, C8004, which has been assigned to APC 5193 (Level 3 Endovascular Procedures). This new code provides reimbursement clarity for mapping procedures conducted prior to transarterial radioembolization ("TARE").

In 2021, we entered into a 5-year Alliance Program (the “MDACC Agreement”) with the University of Texas MD Anderson Cancer Center (“MDACC”) to serve as the lead investigators for the PERIO-01, PERIO-02, and PERIO-03 studies. The term of the agreement was for the later of (i) five years or (ii) until the applicable studies are completed.

Table of Contents

Prior to the expiration of the term of the MDACC Agreement, either party may terminate the MDACC Agreement if the other party commits a material breach of the agreement and fails to cure such breach within 30 days of receiving notice of such breach. Effective February 25, 2025, we modified and extended the MDACC Agreement payment terms with MDACC and added a sixth year. Effective May 27, 2025, we modified and extended our strategic collaboration agreement terms with The University of Texas M.D. Anderson Cancer Center.

Liquidity

As of June 30, 2025, we had cash, cash equivalents and restricted cash of $26.8 million. The Company is still in its early stage, has a history of recurring operating losses, has yet to generate revenues sufficient to create positive cash flow and has an accumulated deficit of $298.2 million as of June 30, 2025. Without additional financing and based on our sales, operations and research and development plans, our management estimates that our existing cash and cash equivalents will be insufficient to fund our projected liquidity requirements for the next 12 months.

In accordance with ASC Topic 205-40, Presentation of Financial Statements, Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, we are required to evaluate whether there is substantial doubt about our ability to continue as a going concern each reporting period. In evaluating our ability to continue as a going concern, management projected our cash flow sources and needs and evaluated that conditions and events have raised substantial doubt about our ability to continue as a going concern within one year after the date that these condensed consolidated financial statements were issued. Management’s plans to address the conditions and events have considered our current projections of future cash flows, current financial condition, sources of liquidity and debt obligations for at least one year from the date of issuance of these condensed consolidated financial statements in considering whether we have the ability to fund future operations and meet our obligations as they become due in the normal course of business.

Our ability to fund future operations and to continue the execution of our long-term business plan and strategy will require that we raise additional capital through a combination of collaborations, strategic alliances and licensing arrangements, and issuance of additional equity and/or debt. We have funded operations resulting in the cumulative net losses of $298.2 million, as of June 30, 2025, principally with proceeds from the sale of preferred stock, from the issuance of debt and convertible debt, and the closing of the Business Combination.

For the six months ended June 30, 2025, we issued $0.3 million of common stock for cash from the exercise of stock options. As described in Note (13) Standby Equity Purchase Agreement, we have the right but not the obligation, to sell up to $30.0 million of our Common Stock at our request under the Standby Equity Purchase Agreement, which we entered into with YA II PN, Ltd. ("Yorkville") on October 2, 2023 (the "SEPA"), subject to terms and conditions specified in the agreement. For the six months ended June 30, 2025, we sold no shares of common stock under the SEPA.

On April 30, 2024 (the "OrbiMed Closing Date"), we entered into the OrbiMed Credit Agreement (the "Credit Agreement") with OrbiMed Royalty & Credit Opportunities IV, LP ("OrbiMed"), a healthcare investment firm. Under the terms of the OrbiMed Credit Agreement, we may borrow up to $50.0 million, of which we immediately drew $25.0 million, before expenses. The remaining debt is available in two increments of $10.0 million and $15.0 million, subject to the achievement of certain revenue targets. On February 18, 2025, we drew the $10.0 million increment before expenses. As part of the First Amendment To Credit Agreement and Registration Rights Agreement, effective March 20, 2025, we received a waiver for the prior default events related to the Series A Convertible Preferred Stock conversions and the Agreement was amended to allow for these conversions going forward. In addition, we received a waiver on March 31, 2025 to extend the timing for the required audited financial statements to occur on or before April 15, 2025. Effective on April 30, 2025, the Second Amendment To Credit Agreement allows for the Company accelerate payment of the Series A Preferred Stock dividends in cash payments in lieu of fractional shares upon conversion of the Preferred Stock shares. See Note (13) Debt for further discussion.

On April 30, 2025, we entered into a securities purchase agreement (the “Purchase Agreement”) with certain institutional and accredited investors named therein (the “Purchasers”) pursuant to which the Company agreed to issue and sell to the Purchasers in a private placement (the “Private Placement”) an aggregate of 5,500,000 shares (the “Shares”) of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), at a purchase price of $4.00 per share.

The Purchase Agreement contains customary representations, warranties and agreements by the Company and the Purchasers, indemnification rights and other obligations of the parties. In connection with the Private Placement, the Company and the Purchasers entered into a registration rights agreement (the “Registration Rights Agreement”) at the closing, pursuant to which the Company granted certain registration rights to the Purchasers with respect to their Shares (as further described below). In addition, the Company committed to use commercially reasonable efforts to satisfy all of its obligations set forth in the Support Agreements (as defined below). The Company and its directors and officers agreed, for a period of 60 days after the date of the Purchase Agreement, to customary lock-up and clear market provisions, as applicable, subject to certain exceptions. The Private Placement closed on May 2, 2025. The

Table of Contents

Company received aggregate gross proceeds from the Private Placement of approximately $22.0 million, before deducting estimated offering fees and expenses payable by the Company.

Outside of these agreements, there can be no assurance that we will be able to raise such additional financing or, if available, that such financing can be obtained on satisfactory terms. If adequate capital resources are not available on a timely basis, we intend to consider limiting our operations substantially. This limitation of operations could include a hiring freeze, reductions in our workforce, reduction in cash compensation, deferring clinical trials and capital expenditures, and reducing other operating costs.

Our current operating plan, which is in part determined based on our most recent results and trends, along with the items noted above, causes substantial doubt to exist about our ability to continue as a going concern and management’s plans do not alleviate the existence of substantial doubt. Our financial statements have been prepared assuming we will continue as a going concern, which contemplates the continuity of normal business activities and realization of assets and settlement of liabilities in the normal course of business, and do not include any adjustments that might be necessary should we be unable to continue as a going concern.

We are subject to various risks and uncertainties frequently encountered by companies in the early stages of growth, particularly companies in the rapidly evolving market for medical technology-based and pharmaceutical products and services. Such risks and uncertainties include, but are not limited to, a limited operating history, need for additional capital, a volatile business and technological environment, the process to test and obtain approval to market nelitolimod, an evolving business model, and demand for our products. To address these risks, we must, among other things, gain access to capital in sufficient amounts and on acceptable terms, maintain and increase our customer base, implement and successfully execute our business strategy, develop nelitolimod, continue to enhance our technology, provide superior customer service, and attract, retain, and motivate qualified personnel. There can be no guarantee that we will succeed in addressing such risks.

Operating results for the six months ended June 30, 2025, are not necessarily indicative of the results that may be expected for any future period or for the year ending December 31, 2025. The accompanying interim unaudited condensed consolidated financial statements should be read in conjunction with the Annual Report on Form 10-K for the year ended December 31, 2024. The December 31, 2024, Condensed Consolidated Balance Sheet is derived from the audited balance sheet included in the Annual Report on Form 10-K for the year ended December 31, 2024. A summary of our significant accounting policies is included in Note 2 to our consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2024. Certain of our accounting policies are considered critical, as these policies are the most important to the depiction of our financial statements and require significant, difficult or complex judgments by us, often employing the use of estimates about the effects of matters that are inherently uncertain. Such policies are summarized below.

(a)Revision of Previously Issued Financial Statements

In connection with the preparation of the consolidated financial statements for the period ended December 31, 2024, we identified errors in our previously filed consolidated financial statements and interim unaudited quarterly condensed consolidated financial statements relating to incorrectly capitalizing the costs of obtaining and maintaining patents.

In accordance with Staff Accounting Bulletins (“SAB”) No. 99, Materiality and SAB No. 108, Considering the Effects of Misstatements when Quantifying Misstatements in the Current Year Financial Statements, we assessed the materiality of these errors to our previously issued consolidated financial statements and interim unaudited condensed consolidated financial statements. Based upon our evaluation of both quantitative and qualitative factors, we concluded the errors were not material to our previously issued consolidated financial statements or interim condensed consolidated financial statements.

Table of Contents

The following table summarize the effects and modification of the revision on our previously issued interim unaudited condensed consolidated financial statements for the six months ended June 30, 2024 (in thousands, except net loss per share) for associated activity all of which occurred through March 31, 2024:

Depreciation and amortization	382		(13)		369
Net cash used in operating activities	(24,289)		—		$	(24,289)

(b)Cash, Cash Equivalents, and Restricted Cash

We consider all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. We invest excess cash primarily in money market funds. Restricted cash is held in a separate account at our bank to support our corporate credit card program and is recorded in other assets on our Condensed Consolidated Balance Sheets.

(c)Concentrations of Credit Risk and Other Risks and Uncertainties

Our cash is deposited primarily with two Federal Deposit Insurance Corporation (“FDIC”) insured financial institutions. At times, the deposits in these institutions may exceed the amount of insurance provided on such deposits. Although we have not experienced any losses in such accounts and believe that we are not exposed to any significant risk on these balances, bank failures, events involving limited liquidity, defaults, non-performance, or other adverse developments that affect financial institutions, or concerns or rumors about such events, may lead to liquidity constraints.

(d)Accounts Receivable and Customer Concentrations

Accounts receivable are recorded at the invoiced amount and do not bear interest. Our payment terms are typically on net 30 day terms. Our accounts receivable balances were $5.6 million and $5.1 million as of June 30, 2025 and December 31, 2024 and $3.6 million as of January 1, 2024, respectively. In accordance with ASC Topic 326, Financial Instruments-Credit Losses, the allowance for credit losses is our best estimate of the amount of probable credit losses in our existing accounts receivable. We review our allowance for credit losses periodically and establish reserves based on management’s expectations of realization based on historical write-off experience, as well as current general economic conditions and expectations regarding collection. Account balances are charged against the allowance after all reasonable means of collection have been exhausted and the potential for recovery is considered remote. We did not incur any credit losses for the six months ended June 30, 2024

Table of Contents

The following table summarizes the credit losses accounts activity for the six months ended June 30, 2025:


	June 30, 2025
Beginning Balance	$	187
Amount charged (recovered) to costs and expenses	(96)
Write-off of uncollectible receivables	—
Ending Balance	$	91

(e)Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ significantly from those estimates. The most significant estimates relate to the valuation of the Initial OrbiMed warrant liability, the contingent earnout liability, the Revenue Base Redemption liability, certain of our clinical expense accruals, and the valuation allowance on deferred tax assets.

(f)Inventory

Inventory is carried at the lower of cost or net realizable value. The balances are recorded on the first-in first-out method. Raw materials consist of purchase material, completed sub-assemblies, and parts for general production use. Finished goods consist of completed products, including direct labor and manufacturing overhead. Write-downs for excess and obsolete inventory are charged to cost of goods sold in the period when conditions giving rise to the write-downs are first recognized. Valuation reserves are recorded when, in our best judgment, we determine the carrying value of the affected inventory may be impaired or its net realizable value exceeds its cost.

(g)Property and Equipment

Property and equipment are recorded at cost. Repairs and maintenance costs are expensed as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, which range from two to seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of estimated useful lives or the lease term.

(h)Leases

We account for leases in accordance with Accounting Standards Codification (“ASC”) Topic 842, Leases. We determine if an arrangement is or contains a lease at contract inception, and, if it does, the lease is recorded on the Condensed Consolidated Balance Sheets with right-of-use assets (“ROU”) representing the Company’s right to use an underlying asset for the lease term and lease liabilities representing our obligation to make lease payments. Lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Lease ROU assets also include the effect of any lease payments made prior to or on lease commencement and excludes lease incentives and initial direct costs incurred, as applicable. As the implicit rate in our leases is typically unknown, we use our incremental borrowing rate based on the information available at the lease commencement date in determining the present value of future lease payments. When calculating our incremental borrowing rates, we consider our credit risk, the term of the lease, and total lease payments and adjusts for the impacts of collateral as necessary. The lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the lease term.

We have elected to not separate lease and non-lease components for any leases within our existing classes of assets and, as a result, account for any lease and non-lease components as a single lease component. We have also elected not to apply the recognition requirement for leases with a term of 12 months or less. We recognize an ROU asset and a lease liability at the lease commencement date.

For operating and finance leases, the lease liability is initially measured at the present value of the unpaid lease payments at the lease commencement date. The lease liability is subsequently measured at amortized cost using the effective-interest method.

The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received.

For operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus (minus) any prepaid (accrued) lease payments, less the unamortized

Table of Contents

balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

For finance leases, the ROU asset is subsequently amortized using the straight-line method from the lease commencement date to the earlier of the end of its useful life or the end of the lease term unless the lease transfers ownership of the underlying asset to the Company or the Company is reasonably certain to exercise an option to purchase the underlying asset. In those cases, the ROU asset is amortized over the useful life of the underlying asset. Amortization of the ROU asset is recognized and presented separately from interest expense on the lease liability. Finance lease ROU assets are presented with property and equipment, net in the Condensed Consolidated Balance Sheets.

(i)Warrant Liabilities

Freestanding financial instruments that permit the holder to acquire shares that are either puttable by the holder, redeemable or contingently redeemable are required to be reported as liabilities in the condensed consolidated financial statements. We present such liabilities on the balance sheets at their estimated fair values. Changes in fair value of the liability are calculated each reporting period, and any change in value are recognized in the Condensed Consolidated Statements of Operations. We have determined that the warrants issued to investors and lenders, which are exercisable for shares of our convertible preferred stock, should be classified as liabilities due to contingent redemption liability of the underlying convertible preferred stock.

In connection with the Business Combination, we assumed warrants to purchase common stock. The warrants include the Public Warrants, Private Placement Warrants and Working Capital Warrants. We value the liability for all of the warrants based on the trading price of the publicly held warrants. See Notes (4) Financial Instruments and (9) Warrants for further discussion.

In connection with our borrowing under the OrbiMed Credit Agreement, we issued the Initial OrbiMed Warrant with the initial $25.0 million draw and the Subsequent OrbiMed Warrant with the subsequent $10.0 million draw, collectively the "OrbiMed Warrants", which we classified as a derivative liability because it did not meet the equity classification criteria under ASC 815-40. We calculated the fair value of the OrbiMed Warrants based on the Black-Scholes-Merton option pricing model. This model considers several variables and assumptions in estimating the fair value of financial instruments, including the per-share fair value of the underlying common stock, exercise price, expected term, risk-free interest rate, expected stock price volatility over the expected term, and expected annual dividend yield. We calculated the expected terms as the contractual expiration period. The risk-free interest rate is estimated using the rate of return on U.S. treasury notes with a life that approximates the expected term. Our common stock does not have sufficient trading history and, therefore, we used the historical volatility of the stock prices of similar publicly traded peer companies. We utilized a dividend yield of zero, as we have no history or plan of declaring dividends on the Company's common stock. See Notes (9) Warrants and (13) Debt.

(j)Revenue Base Redemption Liability

In connection with our the Initial OrbiMed Loan, a “Product Revenue Base” (i.e., with respect to any period, the net revenues for such period from sales of TriNav) on a trailing 12-month basis does not equal or exceed the specified amounts, we will start repaying the outstanding principal amount of the loans under the OrbiMed Credit Agreement. These required revenue thresholds are referred to as the “Revenue Base Redemption Liability." We determined that we should bifurcate and separately recognize the Revenue Base Redemption Liability. We determined the value of the Revenue Base Redemption Liability using a Monte Carlo simulation of future revenue and valuing the Initial Term Loan using the with and without method. The change in fair value of the liability is recorded in the Condensed Consolidated Statement of Operations. See Note (13) Debt for further detail.

(k)Contingent Earnout Liability

In connection with the execution of the Merger Agreement, MTAC entered into a sponsor support agreement (the “Sponsor Support Agreement”) with MedTech Acquisition Sponsor LLC (the "Sponsor”), Legacy TriSalus and MTAC’s directors and officers (the Sponsor and MTAC’s directors and officers, collectively, the “Sponsor Holders”). Pursuant to the Sponsor Support Agreement, 3,125,000 shares of common stock in the Company ("Common Stock") held by the Sponsor Holders immediately after the Closing Date (such shares, the “Sponsor Earnout Shares”) became unvested and subject to potential forfeiture if certain triggering events are not achieved prior to the 5th anniversary of the Closing Date (the “Earnout Period”). The Sponsor Earnout Shares are classified as a liability in the Company’s Consolidated Balance Sheets because they do not qualify as being indexed to the Company’s own stock. The earnout liability was initially measured at fair value at the Closing Date using a Monte Carlo simulation of our future stock price and is subsequently remeasured at the end of each reporting period. The change in fair value of the earnout liability is recorded in the Condensed Consolidated Statements of Operations. See Notes (4) Financial Instruments and (8) Contingent Earnout Liability for further detail.

(l)Standby Equity Purchase Agreement

In October 2023, we entered into the SEPA with Yorkville. Pursuant to the SEPA, we have the right, but not the obligation, to sell to Yorkville up to $30.0 million of shares of Common Stock at our request at any time during the 24 months following the execution of the SEPA, subject to certain conditions. We evaluated the contract that includes the right to require Yorkville to purchase shares of common stock in the future (“put right”) considering the guidance in ASC 815-40, Derivatives and Hedging — Contracts on an Entity’s Own Equity and concluded that it is an equity-linked contract that does not qualify for equity classification, and therefore requires fair value accounting. Each period, we analyze the terms of the freestanding put right and record the balance as a liability. Changes in the fair value are recognized in earnings. See Note (12) Standby Equity Purchase Agreement for further detail.

(m)Impairment and Disposal of Long-Lived Assets

We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is generally measured by a comparison of the carrying amount of the asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amounts of the assets exceed the estimated fair values of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell.

(n)Share-Based Compensation

We account for all employee share-based compensation awards by recording expense based on the estimated fair value of the awards at the time of grant using the Black-Scholes-Merton option valuation model (“Black-Scholes”) for stock options and price of our common stock on the grant date for restricted stock units ("RSUs") and performance stock units ("PSUs"). The determination of fair value using an option-pricing model is affected by the estimated fair value of the Company’s stock, as well as assumptions regarding a number of variables including, but not limited to, the fair value of underlying stock at the grant date, expected volatility of the underlying stock over the term of the awards, projected employee stock option exercise behaviors, and risk-free interest rates. We have elected to not include an estimated forfeiture rate in our share-based compensation expense recognition, in accordance with ASC Topic 718, Compensation — Stock Compensation, and we account for forfeitures in the period in which they occur. The estimated fair value of options, RSUs and PSUs granted is recognized as compensation expense on a straight-line basis over the expected life for each separately vesting portion of the awards. All shares issued upon the exercise of stock options and vesting of RSUs and PSUs are from our reserved authorized common stock.

(o)Revenue Recognition

Our revenue is derived from the shipments of our PEDD infusion systems to our customers. Our customers are generally comprised of hospitals, clinics and physicians. Under ASC Topic 606, Revenue Recognition, we evaluate five steps to determine the appropriate timing and amount to recognize revenue. The five steps are:

i.Identify the contract — We do not maintain long-term contracts with our customers. Typically, customers will submit a purchase order to us for delivery of a quantity of our products, which incorporate enforceable rights and obligations constituting the contract with the customer.

ii.Identify the performance obligation — Our performance obligation is to deliver the ordered products in accordance with the terms of the purchase order, which constitutes a single performance obligation. We do not have any on-going service obligation after delivery and only offer our customers an assurance-type warranty, which provides assurance the product will work as intended.

iii.Determine the transaction price — We maintain a single sales price for each of our products, which is generally fixed. For customers with rebate agreements, the rebates are accounted for within a contra-revenue account at the time the rebate milestone is achieved. We do not have a history of any significant refunds, allowances or other concessions provided to our customers from the agreed-upon sales price after delivery of the product. Refunds, allowances or other concessions are accounted for as a reduction of revenue.

iv.Allocate the transaction price — We do not have multiple performance obligations to complete when we fulfill a purchase order, as such, the transaction price is allocated fully to the units being sold.

v.Recognize revenue — We recognize revenue at the point-in-time when the units for a purchase order have been shipped and control of the units has transferred to the customer, as evidenced by the delivery terms on the shipping documents. Typically, we ship Ex Works; therefore, we recognize revenue when the shipment leaves our premises. In certain cases, the purchase order specifies alternate shipping terms, usually DAP (delivery at place). In those cases, we defer revenue recognition until we are assured the units have been delivered and control has transferred to the customer. Our sale team is able to make in-person sales. When this

Table of Contents

occurs, the revenue in not recognized until we receive a Purchase Order ("P.O.") from the customers, with the inventory treated as consignment until the time receiving the P.O. Shipping and handling activities are not considered to be a separate performance obligation; therefore, the costs are considered to be a fulfillment cost and the expenses are accounted for within cost of goods sold.

We provide certain customers with rebates that are explicitly stated in our contracts and are recorded as a reduction of revenue in the period the conditions for the rebates are achieved. The rebates result from performance-based offers that are primarily based on attaining contractually specified sales volumes. Subsequent to a rebate being earned, the customer receives a credit to apply to future purchases. We recognized rebates of $0.2 million and $0.4 million, respectively, in the three and six months ended June 30, 2025compared to $0.1 million and $0.2 million, respectively, in the three and six months ended June 30, 2024.

(p)Research and Development

Research and development (“R&D”) costs include our engineering, regulatory, pre-clinical and clinical activities. R&D costs are expensed as incurred. The costs are related to internal headcount and external service we purchase, such as pre-clinical supplies and materials, clinical study management and supplies, and consulting related to our R&D. There were no development milestone payments to Dynavax for nelitolimod for the six months ended June 30, 2025 and 2024. See Note (11) Dynavax Purchase for further discussion of Dynavax.

We are required to estimate our expenses resulting from our obligations under agreements with vendors, consultants, and contract research organizations, in connection with conducting R&D activities. The financial terms of these contracts are subject to negotiations, which vary from agreement to agreement and may result in payment flows that do not match the periods over which goods or services are provided. We reflect R&D expenses in our condensed consolidated financial statements by matching those expenses with the period in which services and efforts are expended. We account for these expenses according to the progress of the agreements, along with preparation of financial models, taking into account discussions with research and other key personnel as to the progress of studies or other services being performed. To date, we have had no material differences between our estimates of such expenses and the amounts actually incurred. Nonrefundable advance payments for goods and services are deferred and recognized as expense in the period that the related goods are consumed or services are performed.

(q)Segment Reporting

Our Chief Operating Decision Maker (“CODM”), the Chief Executive Officer ("CEO"), reviews our financial information on a consolidated basis for purposes of allocating resources and evaluating its financial performance. The CEO considers recommendations from the Chief Financial Officer ("CFO") and reviews the Monthly Financial Report ("MFR"), including financial information and the Company’s performance highlights, such as revenue, accounts receivable and inventory balances, cash flows and cash on-hand, operational expenditures and headcount. Based on the Company’s condensed consolidated financial information, the CEO makes the key operating decisions and determines how resources should be allocated. Once the CEO has decided, the CEO and CFO are responsible for carrying out the CEO’s decisions. All of our customers and long-lived assets are located in the United States. Since the Company operates as a single reporting segment, all required segment reporting disclosures can be found in the condensed consolidated financial statements. Accordingly, we have determined we operate as a single reportable segment within a single geographic area.

(r)Advertising

Advertising expense, which is included in sales and marketing costs, is expensed as incurred, and expense for the three and six months ended June 30, 2025 were $0.4 million and $0.6 million, respectively, and three and six months ended June 30, 2024 was $0.2 million and $0.3 million, respectively.

(s)Income Taxes

We account for income taxes pursuant to ASC Topic 740, Income Taxes, which requires the use of the asset-and-liability method of accounting for deferred income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is recorded to the extent it is more likely than not that a deferred tax asset will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date.

The Company recognizes the effect of income tax positions when it is more likely than not, based on technical merits, that the position will be sustained upon examination. Through June 30, 2025, management determined that no

Table of Contents

uncertain tax positions have been taken or are expected to be taken that could have a material effect on the Company’s income tax liabilities.

(t)Net Loss per Share

Net loss per share is calculated using the weighted average number of shares and dilutive common stock equivalents outstanding during the period. Warrants, convertible preferred stock, stock options, and restricted stock units, as described in Notes (9) Warrants, (14) Convertible Preferred Stock, and (16) Share-Based Compensation, are considered to be common stock equivalents. Potentially dilutive shares are excluded from the computation of earnings per share if their effect is anti-dilutive. As we reported a net loss for the three and six months ended June 30, 2025 and 2024, all potentially dilutive shares were excluded from net loss per share in both periods. See Note (15) Net Loss Per Share for further details.

(u)Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In March 2024, the FASB issued ASU 2024-01, Compensation - Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards, which clarifies the guidance on ASC Topic 718 by illustrating how to apply the scope guidance to determine whether a profit interest award should be accounted for as a shared-based payment arrangement under ASC 718 or another accounting standard (e.g., employee profit-sharing arrangement under ASC 710). The ASU aims to reduce the complexity diversity in practice by adding an example to ASC 718 that describes four fact patterns and illustrates how an entity evaluates common terms and characteristics of profit interests and similar awards to reach a conclusion about whether an award meets the scope conditions in ASC 718-10-15-3. The ASU is effective for all public entities for fiscal years beginning after December 15, 2024 and interim periods within those fiscal years. We adopted ASU 2024-01 on January 1, 2025. The effect of the adoption had no impact on our condensed consolidated financial statements.

In March 2024, the FASB issued ASU 2024-02, Codification Improvements — Amendments to Remove References to the Concept Statements, which removes references to the Board's concepts statement from the FASB Accounting Standards Codification (the "Codification" or ASC). The ASU is part of the Board’s standing project to make “Codification updates for technical corrections such as conforming amendments, clarifications to guidance, simplifications to wording or the structure of guidance, and other minor improvements.” Before establishing the Codification in 2009, the FASB used or referred to the concepts statements as part of its standard setting. However, the Board is now removing those references since “references to the Concepts Statements in the Codification could imply that the Concepts Statements are authoritative." The amendment is effective for all public entities for fiscal years beginning after December 15, 2024. Those who adopt the amendments in an interim period would have to adopt them as of the beginning of the fiscal year that includes that interim period. We adopted ASU 2024-02 on January 1, 2025. The effect of the adoption had no impact on our condensed consolidated financial statements.

Accounting Pronouncements Not Yet Adopted

In October 2023, the FASB issued ASU No. 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative. The amendments in ASU 2023-06 update requirements in various disclosure areas, including the statement of cash flows, earnings per share, debt, and equity. The amendments in ASU 2023-06 will be effective on the date the related disclosures are removed from Regulation S-X or Regulation S-K by the SEC and will no longer be effective if the SEC has not removed the applicable disclosure requirement by June 30, 2027. Early adoption is prohibited. We are currently evaluating the impact the adoption of this ASU will have on our condensed consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures. Under the ASU, Public Business Entity ("PBE") must annually "(1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5% of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate)." This guidance is effective for public companies for annual periods beginning after December 15, 2024. For other companies, the amendments are effective for annual periods beginning after December 15, 2025. We are currently evaluating the impact the adoption of this ASU will have on our condensed consolidated financial statements.

In November 2024, the FASB issues ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, and in January 2025, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. ASU 2024-03 requires additional disclosure of the nature of expenses included in the income statement as well as disclosures about specific types of expenses included in the expense captions

Table of Contents

presented in the income statement. ASU 2024-03, as clarified by ASU 2025-01. The amendment applies to all public business entities and is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. The requirements will be applied prospectively with the option for retrospective application. Early adoption is permitted. We are currently evaluating the impact the adoption of this ASU will have on our condensed consolidated financial statements.

In November 2024, the FASB issues ASU 2024-04, Debt - Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments, which amends ASC 470-20, Debt: Debt With Conversion and Other Options, to clarify the requirements related to accounting for the settlement of a debt instrument as an induced conversion. Based primarily on the consensus-for-exposure reached on Issue 23-A, Induced Conversion of Convertible Debt Instruments, by the Emerging Issues Task Force on September 14, 2023. The ASU is intended to “improve the relevance and consistency in application of the induced conversion guidance in Subtopic 470-20 for (a) convertible debt instruments with cash conversion features and (b) debt instruments that are not currently convertible.” The amendments are effective for all entities for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of the annual reporting period for all entities that have adopted the amendments in Update 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. We are currently evaluating the impact the adoption of this ASU will have on our condensed consolidated financial statements.

(3) Business Combination

On August 10, 2023, we consummated the previously announced merger pursuant to the Merger Agreement by and among MTAC, Merger Sub, Inc., and TriSalus Life Sciences, Inc. Upon the closing of the transactions contemplated by the Merger Agreement, Merger Sub merged with and into Legacy TriSalus (the “Business Combination”) with Legacy TriSalus surviving the merger as a wholly owned subsidiary of MTAC, renamed “TriSalus Operating Life Sciences, Inc.” In addition, in connection with the consummation of the Business Combination, MTAC was renamed “TriSalus Life Sciences, Inc.”

Immediately prior to the effective time of the Business Combination, each in-the-money warrant of Legacy TriSalus that was unexercised and unexpired was automatically net exercised into the respective series of preferred stock of Legacy TriSalus. Each share of preferred stock of Legacy TriSalus (“Legacy TriSalus Preferred Stock”) that was issued and outstanding was then automatically converted into shares of common stock of Legacy TriSalus (“Legacy TriSalus Common Stock”) in accordance with the Amended and Restated Certificate of Incorporation of Legacy TriSalus at the then current conversion price, such that each converted share of Legacy TriSalus Preferred Stock was no longer outstanding and ceased to exist, and each holder of Legacy TriSalus Preferred Stock thereafter ceased to have any rights with respect to such securities.

Pursuant to the terms of the Merger Agreement, the existing stockholders of Legacy TriSalus exchanged their equity holdings at an exchange ratio of 0.02471853 (the “Exchange Ratio”) for an aggregate of 21,999,886 shares of our Common Stock. In addition, MTAC had previously issued public warrants and private placement warrants (collectively, the “MTAC Warrants”) as part of its initial public offering in November 2020. None of the terms of the MTAC Warrants were modified as a result of the Business Combination. See Note (9) Warrants for additional discussion of the warrants.

PIPE Financing

On the Closing Date, certain investors agreed to purchase an aggregate of 4,015,002 newly-issued shares of Series A Convertible Preferred Stock at a purchase price of $10.00 per share for an aggregate purchase price of $40.2 million, pursuant to separate subscription agreements dated June 7, 2023, and July 4, 2023 (collectively, the “Subscription Agreements”). See Note (14) Convertible Preferred Stock for further discussion.

Sponsor Earnout

In connection with the execution of the Merger Agreement, MTAC entered into the Sponsor Support Agreement. Pursuant to the Sponsor Support Agreement, the 3,125,000 Sponsor Earnout Shares became unvested and subject to potential forfeiture if certain triggering events are not achieved prior to the 5th anniversary of the Closing Date. Pursuant to the Sponsor Support Agreement, (i) 25% of the shares of our Common Stock held by the Sponsor Holders will only vest if, during the five years period following the Closing, the volume weighted average price of our Common Stock equals or exceeds $15.00 for any 20 trading days within a period of 30 consecutive trading days, (ii) 25% of the shares of our Common Stock held by the Sponsor Holders will only vest if, during the five years period following the Closing, the volume weighted average price of our Common Stock equals or exceeds $20.00 for any 20 trading days within a period of 30 consecutive trading days, (iii) 25% of the shares of our Common Stock held by the Sponsor Holders will only vest if, during the five years period following the Closing, the volume weighted average price of our Common Stock equals or exceeds $25.00 for any 20 trading days within a period of 30 consecutive trading

days; and (iv) 25% of the shares of our Common Stock held by the Sponsor Holders will only vest if, during the five years period following the Closing, the volume weighted average price of our Common Stock equals or exceeds $30.00 for any 20 trading days within a period of 30 consecutive trading days. Additionally, the Sponsor Earnout Shares will vest if there is a change in control of our company on or before the 5th anniversary of the Closing Date that results in the holders of our Common Stock receiving a price per share equal to or in excess of the applicable earnout targets. Any such shares held by the Sponsor Holders that remain unvested after the 5th anniversary of the Closing will be forfeited. See Note (8) Contingent Earnout Liability for additional discussion of the Sponsor Earnout Shares and the liability we have recorded for them.

(4) Financial Instruments

Our financial instruments consist of cash and cash equivalents, accounts receivable, trade accounts payable, tranche and warrant liabilities to purchase preferred stock, the contingent earnout liability and the warrant liability and revenue based redemption liability related to the Initial OrbiMed Credit Agreement. The carrying values of these financial instruments (other than the contingent earnout liability, tranche liabilities, revenue based redemption liability, and warrant liabilities, which are held at fair value) approximate fair value through the use of publicly available market prices as of June 30, 2025, and December 31, 2024. In general, asset and liability fair values are determined using the following categories:

Level 1 — Inputs utilize quoted prices in active markets for identical assets or liabilities.

Level 2 — Inputs include quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly.

Level 3 — Inputs are unobservable inputs and include situations where there is little, if any, market activity for the balance sheet items at period end. Pricing inputs are unobservable for the terms and are based on the Company’s own assumptions about the assumptions that a market participant would use.

Our warrant, earnout liabilities, SEPA, tranche, and revenue base redemption feature are measured at fair value on a recurring basis.

At the Closing Date, we assumed warrants to purchase 14,266,605 shares of common stock for $11.50 (see Note (9) Warrants). Of these, 8,333,272 were traded publicly (the "Public Warrants"), 5,933,333 were privately held (the 4,933,333 "Private Placement Warrants" and 1,000,000 "Working Capital Warrants" and together with the Public Warrants, the "SPAC Warrants"). We determined the fair value of the earnout liability to be $28.9 million based on a Monte Carlo simulation of future trading prices for our common stock. See Note (8) Contingent Earnout Liability for further discussion.

The carrying amount of our outstanding SPAC warrants liabilities was $9.3 million and $7.9 million, respectively, at June 30, 2025 and December 31, 2024. The carrying amount of outstanding earnout liability was $7.5 million and $7.4 million, respectively, at June 30, 2025 and December 31, 2024. The carrying values of the warrant liabilities represent the remeasurement to fair value each reporting period based on Level 1 inputs for the publicly traded Public Warrants and Level 2 inputs for the Private Placement Warrants and Working Capital Warrants. The carrying amounts of the contingent earnout liability and SEPA derivative liability represent the remeasurement to fair value each reporting period based on unobservable, or Level 3 inputs, using assumptions made by us, including the market price of our common stock and the observed volatility of a peer group of companies.

On October 2, 2023, we entered into the SEPA with Yorkville. Upon execution of the SEPA, we determined the fair value of the SEPA derivative liability to be $0.2 million based on a scenario-based model. See Note (12) Standby Equity Purchase Agreement for further discussion. We determined the fair value of the SEPA derivative liability to be $3 thousand and $0.1 million, respectively, at June 30, 2025 and December 31, 2024; we recorded the change in fair value in other income (expense).

In connection with the debt closing with OrbiMed on April 30, 2024, we also issued OrbiMed a warrant to purchase 130,805 shares of our common stock, with the initial exercise price of $9.5562 (the "Initial OrbiMed Warrant") per share, or approximately $1.25 million in the aggregate, assuming none of the Initial OrbiMed Warrant is exercised through a "cashless" exercise. In the three months ended June 30, 2025, the exercise price was adjusted to $8.8398 per share pursuant to the terms of the Initial OrbiMed Warrant, or approximately $1.16 million in the aggregate. On August 15, 2024, at OrbiMed's request, the Initial OrbiMed warrant was split into two separate warrants ("Substitute Warrant Certificate #1" and "Substitute Warrant Certificate #2" and, together, the "OrbiMed Warrants") held by two of OrbiMed's operating entities; one for 92,801 common shares and second for 38,004 common shares, with no change to the related terms and conditions.

In connection with the First Delayed Draw Term Loan Commitment draw on February 18, 2025, we issued the OrbiMed operating entities a warrant to purchase 64,748 and 26,515 shares of our common stock (the "Subsequent OrbiMed Warrant"), with the initial exercise price of $5.4787, or approximately $0.5 million. In the three months

Table of Contents

ended June 30, 2025, the exercise price was adjusted to $5.3322 per share pursuant to the terms of the Initial OrbiMed Warrant, or approximately $0.5 million in the aggregate. The Subsequent OrbiMed Warrant expires on February 18, 2032 (See Notes (9) Warrants and (13) Debt for more information on the OrbiMed Credit Agreement). The Subsequent OrbiMed Warrant collectively with the Initial OrbiMed Warrant (the "OrbiMed Warrants") are accounted for as a liabilities under ASC 815, Derivatives and Hedging, Contracts in Equity's Own Equity ("ASC 815-40").

We use a Black-Scholes option pricing model to estimate the fair value of the OrbiMed Warrant, as warrants give the holders the right, but not the obligation, to purchase the underlying securities at a contractual exercise price. This method utilizes certain unobservable inputs, including the determination of the expected volatility, and is therefore considered a Level 3 fair value measurement. Certain inputs used in this Black-Scholes pricing model may fluctuate in future periods based upon factors that are outside of our control, including potential change in control outside of our control. A significant change in one or more of these inputs used in the calculation of the fair value may cause a significant change to the fair value of the warrant liabilities, which could also result in material non-cash gains or losses being reported in the condensed statement of operations. The expected volatility was implied from a blend of the Company's own common shares and the average historical share volatilizes of several unrelated public companies within the Company's industry that the Company considers to be comparable to its own business. We determined the fair value of the OrbiMed Warrant liability to be $0.7 million and $0.4 million, respectively, at June 30, 2025 and December 31, 2024, and recorded the adjustment to the change in fair value of SEPA, warrant, and revenue base redemption liabilities.

If the “Product Revenue Base” (i.e., with respect to any period, the net revenues for such period from sales of TriNav) on a trailing 12-month basis does not equal or exceed the specified amount as stipulated (see table in Note (13) Debt), we will start repaying the outstanding principal amount in equal monthly installments through April 30, 2029 (the "Maturity Date"). Such repayments will commence in the calendar month immediately following the applicable Test Date per the OrbiMed Credit Agreement (see table in Note (13) Debt) and occur on the last day of each calendar month ("Amortization Payment Date"). The repayments are calculated from the first Amortization Payment Date through the Maturity Date and the balance of the principal amount of the loans under the OrbiMed Credit Agreement shall be repaid on the Maturity Date. The repayments include the applicable Repayment Premium and the Exit Fee (see Note (13) Debt ). The repayment of the loans under the OrbiMed Credit Agreement as aforementioned, is referred to as the “Revenue Base Redemption Liability.” Furthermore, if on the subsequent test date, the revenue-based condition is met, we will stop repaying the outstanding principal amount in equal installments and directly repay the balance amount on the Maturity Date. We determine the value of the Revenue Base Redemption Liability using a Monte Carlo simulation of future revenue and valuing the Term Loan using the with and without method.

On May 24, 2024, we commenced an offer (the “Offer”) to all holders of Public Warrants, Private Placement Warrants and Working Capital Warrants (collectively, the "Exchange Warrants") to receive 0.30 shares of common stock of the Company in exchange for each Exchange Warrant tendered by the holder and exchanged pursuant to the Offer. The Offer expired at one minute after 11:59 p.m., Eastern Standard Time, on June 25, 2024. The Exchange Warrants tendered were comprised of 6,529,954 Public Warrants and 504,685 Private Placement Warrants. We determined the Exchange Warrants met the criteria to be equity classified at June 26, 2024, and that their fair value was $11.9 million. Adjusting for issuance costs of $1.7 million, the net fair value of the Exchange Warrants was $10.2 million. Accordingly, we recorded that amount as a reduction of the warrant liability and a charge to APIC.

The following tables summarize the changes in fair value of our outstanding warrant liabilities, contingent earnout liability, SEPA derivative liability, and revenue base redemption liability for the six months ended June 30, 2025:

(8) Contingent Earnout Liability

In connection with the execution of the Merger Agreement (see Note (3) Business Combination), MTAC entered into the Sponsor Support Agreement. Pursuant to the Sponsor Support Agreement, the 3,125,000 Sponsor Earnout Shares became unvested and subject to potential forfeiture if certain triggering events are not achieved prior to the 5th anniversary of the Closing Date. Pursuant to the Sponsor Support Agreement, (i) 25% of the shares of the unvested Common Stock held by the Sponsor Holders will only vest if, during the five year period following the Closing, the volume weighted average price of our Common Stock equals or exceeds $15.00 for any 20 trading days within a period of 30 consecutive trading days, (ii) 25% of the shares of the unvested Common Stock held by the Sponsor Holders will only vest if, during the five year period following the Closing, the volume weighted average price of our Common Stock equals or exceeds $20.00 for any 20 trading days within a period of 30 consecutive trading days, (iii) 25% of the shares of the unvested Common Stock held by the Sponsor Holders will only vest if, during the five year period following the Closing, the volume weighted average price of our Common Stock equals or exceeds $25.00 for any 20 trading days within a period of 30 consecutive trading days; and (iv) 25% of the shares of the unvested Common Stock held by the Sponsor Holders will only vest if, during the five year period following the Closing, the volume weighted average price of our Common Stock equals or exceeds $30.00 for any 20 trading days within a period of 30 consecutive trading days. Additionally, the Sponsor Earnout Shares will vest if there is a change in control of our company on or before the 5th anniversary of the Closing Date that results in the holders of our Common Stock receiving a price per share equal to or in excess of the applicable earnout targets. Any such shares held by the Sponsor Holders that remain unvested after the 5th anniversary of the Closing will be forfeited.

The estimated fair value of the contingent earnout liability on the Closing Date, August 10, 2023, was $28.9 million, based on a Monte Carlo simulation valuation model. The liability was remeasured to its fair value of $7.5 million and $7.4 million, respectively, as of June 30, 2025 and December 31, 2024. This remeasurement resulted in the recording of a gain of $0.7 million and a loss of $0.1 million, respectively, for the three and six months ended June 30, 2025 compared to a gain of $13.7 million and $9.7 million, respectively, for the three and six months ended June 30, 2024, classified as change in fair value of contingent earnout liability in the Condensed Consolidated Statements of Operations. Assumptions used in the valuation are described below:


	June 30, 2025			December 31, 2024
Current stock price	$	5.45		$	5.01
Expected share price volatility	70.0		%	70.0		%
Risk-free interest rate	3.7		%	4.3		%
Expected term (years)	3.11			3.61
Estimated dividend yield	—		%	—		%

The estimated fair value of the liability was determined using a Monte Carlo simulation valuation model using a distribution of potential outcomes. The inputs and assumptions utilized in the calculation require management to apply judgment and make estimates including:

(a)expected volatility, which is based on the historical equity volatility of publicly traded peer companies for a term equal to the expected term of the earnout period;

(b)expected term, which we based on the earnout period per the agreement;

Table of Contents

(c)risk-free interest rate, which was determined by reference to the U.S. Treasury yield curve for time periods commensurate with the expected term of the earnout period; and

(d)expected dividend yield, which we estimate to be 0% based on the fact that we have never paid or declared dividends.

These estimates may be subjective in nature and involve uncertainties and matters of judgment and therefore cannot be determined with exact precision.

(9) Warrants

Warrants that have not been tendered for exchange and outstanding at June 30, 2025, and December 31, 2024, are as follows:


	June 30, 2025	December 31, 2024
Public Warrants	1,751,825	1,751,825
Private Placement Warrants	4,428,648	4,428,648
Working Capital Warrants	1,000,000	1,000,000
OrbiMed Warrants	222,068	130,805

Total warrants	7,402,541	7,311,278

Public, Private Placement and Working Capital Warrant Liabilities

In connection with consummation of the Business Combination, we assumed the warrant liabilities associated with 8,333,272 Public Warrants. Each Public Warrant is exercisable to purchase one share of common stock at a price of $11.50 per share, subject to adjustment. As of June 30, 2025 and December 31, 2024, there were 1,751,825 Public Warrants outstanding. The Public Warrants expire on August 10, 2028 or earlier upon redemption or liquidation.

The Public Warrants expire 5 years after the completion of the Business Combination or earlier upon redemption or liquidation. We may redeem for cash the outstanding Public Warrants:

a.in whole and not in part;

b.at a price of $0.01 per Public Warrant;

c.upon not less than 30 days’ prior written notice of redemption to each warrant holder; and

d.if, and only if, the reported closing price of the Common Stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30 trading day period ending three business days before we send the notice of redemption to the warrant holders.

If and when the SPAC Warrants become redeemable, we may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

If we call the Public Warrants for redemption, management will have the option to require all holders that wish to exercise the Public Warrants to do so on a “cashless basis.” The exercise price and number of shares of common stock issuable upon exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation. However, except as described below, the warrants will not be adjusted for issuances of common stock at a price below its exercise price. Additionally, in no event will we be required to net cash settle the warrants. Accordingly, the warrants may expire worthless.

In addition to the Public Warrants, we assumed the warrant liabilities associated with 4,933,333 Private Placement Warrants and 1,000,000 Working Capital Warrants. The Private Placement Warrants and Working Capital Warrants are identical to the Public Warrants, except that the Private Placement Warrants and Working Capital Warrants, and the common stock issuable upon the exercise of the Private Placement Warrants and Working Capital Warrants, were not transferable, assignable or saleable until 30 days after the completion of the Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants and Working Capital Warrants are exercisable on a cashless basis and are non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants and Working Capital Warrants are held by someone other than the initial purchasers or their permitted transferees, they will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants. As of June 30, 2025 and December 31, 2024, there were 4,428,648 Private Placement Warrants and 1,000,000 Working Capital Warrants outstanding.

Table of Contents

We determined that the Public Warrants, Private Placement Warrants, and Working Capital Warrants do not meet the criteria to be equity classified and should be recorded as liabilities. Our analysis concluded liability classification under ASC 815, Derivatives and Hedging, as these warrants include a provision that could allow cash settlement upon an event outside our control, and such event may not result in a change in control of the Company. As a result, the Private and Public Warrants do not meet the criteria for equity classification.

At the close of the Business Combination, the fair values of the Public Warrants, Private Placement Warrants, and Working Capital Warrants were $1.5 million, $0.9 million, and $0.2 million, respectively. As of June 30, 2025, the fair values of the Public Warrants, Private Placement Warrants and Working Capital Warrants were $2.3 million, $5.7 million, and $1.3 million, respectively. As of December 31, 2024, the fair values of the Public Warrants, Private Placement Warrants and Working Capital Warrants were $1.9 million, $4.9 million, and $1.1 million. The fair value of the Public Warrants has been measured based on the quoted price of such warrants on the Nasdaq Global Market. The transfer of Private Placement Warrants or Working Capital Warrants to anyone outside of a small group of individuals who are permitted transferees would result in the Private Placement Warrants and Working Capital Warrants having substantially the same terms as the Public Warrants. Therefore, we determined that the fair value of each Private Warrant and Working Capital Warrant is equivalent to that of each Public Warrant.

On May 24, 2024, we commenced (i) the Offer and (ii) the solicitation of consent (the “Consent Solicitation”) from holders of the Exchange Warrants to amend the Warrant Agreement, dated as of December 17, 2020 (the “Warrant Agreement” and such amendment, the “Warrant Amendment”), by and between the Company and Continental Stock Transfer & Trust Company, which governs all of the Exchange Warrants.

The Offer and Consent Solicitation expired at one minute after 11:59 p.m., Eastern Standard Time, on June 25, 2024. The Exchange Warrants tendered were comprised of 6,529,954 Public Warrants and 504,685 Private Placement Warrants, which represents approximately 78.8% and 10.2% of the outstanding warrants of each respective class. The Warrants were validly tendered and not validly withdrawn prior to the expiration of the Offer and Consent Solicitation. No Working Capital Warrants were tendered. We determined the Exchange Warrants met the criteria to be equity classified at June 26, 2024, and that their fair value was $11.9 million. Accordingly, we recorded that amount as a reduction of the warrant liability and a charge to APIC, partially offset by issuance costs of $1.7 million. On July 1, 2024, we issued 2,110,366 shares of common stock in exchange for the Exchange Warrants.

In addition, the Warrant Amendment was entered into with respect to the Public Warrants. As a result all (and not less than all) of the outstanding Public Warrants may be exchanged, at our option, at any time while they are exercisable and prior to their expiration, at the office of the warrant agent, upon notice to the holders of the then outstanding Public Warrants, at the exchange rate of 0.27 shares of Common Stock per Public Warrant (subject to equitable adjustment by us in the event of any stock splits, stock dividends, recapitalizations or similar transaction with respect to the Common Stock).

The following table summarizes activity in the Public Warrants, Private Placement Warrants, Working Capital Warrants and Exchange Warrants in the six months ended June 30, 2025 and 2024.

OrbiMed Warrants

In connection with the closing of the OrbiMed Credit Agreement, we also issued OrbiMed a warrant to purchase 130,805 shares of our common stock (the "Warrant Shares"), with the initial exercise price of $9.5562, (the "Exercise Price") per share, or approximately $1.25 million in the aggregate, assuming none of the Initial OrbiMed Warrant is exercised through a "cashless" exercise. In the three months ended June 30, 2025, the exercise price was adjusted to $8.8398 per share pursuant to the terms of the Initial OrbiMed Warrant, or approximately $1.16 million in the aggregate. The Initial OrbiMed Warrant expires on April 30, 2031 (the "Expiration Date"). On each of the closings of the Delayed Draw Commitment Amounts, if any, we agreed to issue additional warrants to purchase a number of shares of our common stock determined by dividing 5.0% of the applicable Delayed Draw Commitment Amount by

Table of Contents

the 10-day volume weighted average sale price of our common stock as of the issue date (the “Subsequent OrbiMed Warrants” and collectively, with the Initial OrbiMed Warrant, the “OrbiMed Warrants” and together with the SPAC Warrants, the “Warrants”). The Subsequent OrbiMed Warrants will expire seven years from each applicable issuance date, if any. In connection with the OrbiMed Warrants, we entered into a Registration Rights Agreement with OrbiMed (the “OrbiMed Registration Rights Agreement”), whereby OrbiMed will have certain customary registration rights with respect to the shares of common stock underlying the OrbiMed Warrants. In connection with the First Delayed Draw Term Loan Commitment draw on February 18, 2025, we issued the OrbiMed operating entities a warrant to purchase 64,748 and 26,515 shares of our common stock (the "Subsequent OrbiMed Warrant"), with the initial exercise price of $5.4787, or approximately $0.5 million. In the three months ended June 30, 2025, the exercise price was adjusted to $5.3322 per share pursuant to the terms of the Subsequent OrbiMed Warrant, or approximately $0.49 million in the aggregate. The Subsequent OrbiMed Warrant expires on February 18, 2032.

The OrbiMed Warrants may be exercised in whole or in part, at any time prior to the Expiration Date (the "Exercise Period"), by either:

a.making a payment to the Company, in an amount in immediately available funds equal to the aggregate Exercise Price to be paid upon the exercise of the OrbiMed Warrants; or

b.instructing the Company to withhold a number of Warrant Shares then issuable upon exercise of the OrbiMed Warrants with an aggregate fair market value as of the exercise date equal to such aggregate Exercise Price to be paid upon the exercise of the OrbiMed Warrants (the “Cashless Exercise”).

If either upon (i) the occurrence of the Expiration Date, or (ii) the date on which a Sale of the Company (defined in the OrbiMed Warrants) is consummated pursuant to which the sole consideration payable to the Company or its stockholders in respect of such sale transaction consists of cash, marketable securities or a combination thereof, and the per share fair market value of a Warrant Share is greater than the exercise price, any portion of the OrbiMed Warrants that remains unexercised on such date shall be deemed to have been exercised automatically pursuant to a Cashless Exercise (the “Automatic Cashless Exercise”).

Ownership Cap

The Holder in any circumstance cannot exercise the OrbiMed Warrants if such exercise would result in the holder and its affiliates to own more than 9.99% of the Company's common stock (the “Ownership Cap”).

Adjustments

The Exercise Price and the number of Warrant Shares underlying the OrbiMed Warrants are subject to certain anti-dilutive adjustments. These are triggered by events such as stock splits, reclassification of shares, combinations, or substitutions. Additionally, the Exercise Price will be adjusted if shares (which include shares, options, and convertible securities settled in common stock) are issued at a price per share less than the current Exercise Price. These adjustments are collectively referred to as "Warrant Adjustments.”

If we declare or pay a dividend or distribution on our outstanding common shares payable in cash, capital securities or other property, the Holder shall be entitled to receive, at the time such dividend or distribution is paid, without additional cost to the Holder, the total number and kind of cash, capital securities or other property which the Holder would have received had the Holder owned the Warrant Shares of record as of the date such dividend or distribution was paid (the “Pro-Rata Distribution”).

Additionally, the OrbiMed Warrants are subject to customary price-based anti-dilution protections, such that, in certain circumstances, if we issue shares of our common stock below the current exercise price of the Initial OrbiMed Warrant, the exercise price of the OrbiMed Warrants will be adjusted downward based on such issuance. As a result of any adjustments, the amount of proceeds we receive from the exercise of the OrbiMed Warrants would be less than the amount we would receive immediately prior to such adjustment. In the three months ended June 30, 2025, the exercise price of the Initial OrbiMed Warrant was adjusted to $8.8398 per share, while the Subsequent OrbiMed Warrant was adjusted to an exercise price of $5.3322.

Transfers of OrbiMed Warrants

The OrbiMed Warrants may be transferred or assigned in whole or in part, subject to compliance with applicable federal and state securities laws.

Allocation of Proceeds and Issuance Costs

The agreement explicitly permits the settlement of the OrbiMed Warrants in a cashless manner (i.e., net share settlement) and not indexed to the Company's own stock, therefore, it is considered as a derivative instrument and will be classified as a liability and is subsequently measured at fair value with changes reported to earnings following the proceeds from the issuance of the Initial Term Loan.

Table of Contents

The fair value of the Initial OrbiMed Warrant was measured using the Black-Scholes option pricing model. The key inputs used in the valuations were as follows:


	June 30, 2025	December 31, 2024
Expected term (years)	5.8	6.3
Risk free interest rate	3.9%	4.5%
Expected volatility	70.0%	70.0%
Dividend yield	0	0
Exercise price	$8.8398	$9.3722
Stock price	$5.45	$5.01

The fair value of the Subsequent OrbiMed Warrant was measured using the Black-Scholes option pricing model. The key inputs used in the valuations were as follows:


	June 30, 2025	February 18, 2025
Expected term (years)	6.6	7.0
Risk free interest rate	4.0%	4.1%
Expected volatility	70.0%	70.0%
Dividend yield	0	0
Exercise price	$5.3322	$5.4787
Stock price	$5.45	$5.69

The inputs utilized by management to value the warrant liabilities are subjective. The assumptions used in calculating the fair value of the warrant liabilities represent our best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and we use different assumptions, the fair value of the warrant liabilities may be materially different in the future.

(10) Income Taxes

At the end of each interim period, we make our best estimate of the effective tax rate expected to be applicable for the full calendar year and use that rate to provide for income taxes on a current year-to-date basis before discrete items. If a reliable estimate cannot be made, we may make a reasonable estimate of the annual effective tax rate, including use of the actual effective rate for the year-to-date. The impact of the discrete items is recorded in the quarter in which they occur.

We utilize the balance sheet method of accounting for income taxes and deferred taxes which are determined based on the differences between the condensed consolidated financial statements and tax basis of assets and liabilities given the provisions of the enacted tax laws. In assessing the realizability of the deferred tax assets, we considered whether it is more likely than not that some portion or all of the deferred tax assets will not be realized through the generation of future taxable income. In making this determination, we assessed all of the evidence available at the time including recent earnings, forecasted income projections, and historical financial performance. We have fully reserved deferred tax assets as a result of this assessment.

Based on our full valuation allowance against the net deferred tax assets, our effective federal tax rate for the calendar year is zero, and we recorded an immaterial income tax expense in the three and six months ended June 30, 2025 and 2024. We continue to believe it is more likely than not that some or all of the benefits from its deferred tax assets will not be realized, and accordingly, believe a valuation allowance is still warranted on these assets. Management assesses the available positive and negative evidence, including future reversals of temporary differences, tax-planning strategies and future taxable income, to estimate whether sufficient future taxable income will be generated to permit the use of deferred tax assets. If we conclude it is more likely than not that a portion, or all, of our deferred tax assets will not be realized, the deferred tax asset is reduced by a valuation allowance. A significant piece of objective negative evidence evaluated is the cumulative loss incurred over recent years. Such objective negative evidence limits the ability to consider other subjective positive evidence. The amount of the deferred tax asset considered realizable could be adjusted if estimates of future taxable income change or if objective negative evidence, in the form of cumulative losses, is no longer present and additional weight is given to subjective evidence such as future growth. We evaluate the appropriateness of its valuation allowance on a quarterly basis.

(11) Dynavax Purchase

We purchased all of the intellectual property and trial drug substance for nelitolimod from Dynavax Technologies (“Dynavax”) in 2020. This was a purchase of in-process research and development (“IPR&D”). Nelitolimod, an investigational agent in development, is a toll-like receptor 9 (“TLR9”) agonist which is believed to bind to the TLR9 receptors found on suppressive immune cells including myeloid-derived suppressor cells (“MDSCs”) and antigen-presenting immune cells. We believe that nelitolimod, when delivered using our PEDD devices, can improve therapeutic distribution to solid tumors and improve outcomes for liver metastases and LA-PDAC.

Payments under the Dynavax purchase agreement consist of: (a) an upfront payment of $9,000, (b) milestone payments upon the achievement of certain development and commercial milestones, and (c) royalty payments based on aggregate annual net sales after nelitolimod receives Food and Drug Administration ("FDA") approval to be sold.

The milestone payments range from $1,000 to $10,000, triggered by development achievements for each of up to four indications. The development milestone payments cannot exceed $170,000. We have made milestone payments of $1,000 in September 2021, after initiating our clinical study of uveal melanoma liver metastases, June 2022, after initiating our clinical study for primary liver tumors, and August 2023, after initiating our clinical study for LA-PDAC. In aggregate, the commercial milestones shall not exceed $80,000. We will also pay annual royalties at the rate of 10.0% for aggregate annual net sales less than or equal to $1,000,000 and 12.0% for aggregate annual net sales above that amount.

We record the milestone payments in R&D expense when they are incurred. The milestone payments and royalty payments are contingent upon future events and therefore will also be recorded as expense when it is probable that a milestone has been achieved or when royalties are due. During the three and six months ended June 30, 2025 and 2024, we made no payments to Dynavax.

(12) Standby Equity Purchase Agreement

In October 2023, we entered into the SEPA with Yorkville. Yorkville is a fund managed by Yorkville Advisors Global, LP.

Pursuant to the SEPA, we have the right, but not the obligation, to sell to Yorkville up to $30.0 million of Common Stock, par value $0.0001 per share, at our request any time during the commitment period commencing on October 2, 2023 (the “Effective Date”), and terminating on the first day of the month following the 24-month anniversary of the Effective Date. Each issuance and sale to Yorkville under the SEPA (an “Advance”) is subject to a maximum limit equal to the greater of: (i) an amount equal to 100% of the average of the daily volume of the Common Stock on the Nasdaq Stock Market (“Nasdaq”) for the 10 trading days immediately preceding an Advance notice, or (ii) 1,000,000 shares of Common Stock. At our election, the shares will be issued and sold to Yorkville at a per-share price equal to: (i) 96.0% of the Market Price (as defined below) for any period commencing on the receipt of the Advance notice by Yorkville and ending on 4:00 p.m. New York City time on the applicable Advance notice date (the “Option 1 Pricing Period”), or (ii) 97.0% of the Market Price for any three consecutive trading days commencing on the Advance notice date (the “Option 2 Pricing Period,” and each of the Option 1 Pricing Period and the Option 2 Pricing Period, a “Pricing Period”). “Market Price” is defined as, for any Option 1 Pricing Period, the daily volume-weighted average price (“VWAP”) of the Common Stock on Nasdaq, and for any Option 2 Pricing Period, the lowest VWAP of the Common Stock on the Nasdaq during the Option 2 Pricing Period. The Advances are subject to certain limitations, including that Yorkville cannot purchase any shares that would result in it beneficially owning more than 4.99% of the outstanding voting power or Common Stock. Further, Yorkville cannot purchase shares that would result in it acquiring more than 5,260,704 shares of Common Stock, which represents 19.99% of the outstanding Common Stock, as of the Effective Date of SEPA.

As described in Note (2) Summary of Significant Accounting Policies, the SEPA is accounted for as a derivative and is recognized as a liability measured at fair value in accordance with ASC 820. We intend to utilize the SEPA to access capital to fund our operations. We did not issue any Advances during three and six months ended June 30, 2025.

The estimated fair value of the SEPA liability on December 31, 2024, was $0.1 million, which was determined using a scenario-based valuation model. The liability was remeasured to its fair value of $3.1 thousand as of June 30, 2025, and is classified within other long-term liabilities in the Condensed Consolidated Balance Sheets. This remeasurement resulted in the recognition of a gain of $0.02 million and $0.05 million for three and six months ended June 30, 2025, classified as change in fair value of SEPA, tranche and warrant liabilities in the Condensed Consolidated Statement of Operations. Assumptions used in the valuation are described below:

Table of Contents


Valuation assumptions:	June 30, 2025			December 31, 2024
Expected draws	$	2,000		$	2,000
Expected probability of draws	5%			90		%
Risk-free interest rate	4.3		%	4.4		%

The estimated fair value of the liability was determined using a scenario-based valuation model which assigned a probability to a number of different outcomes. The inputs and assumptions utilized in the calculation require management to apply judgment and make estimates including:

(a)total expected draws of $2.0 million, respectively, at June 30, 2025, and December 31, 2024 through the issuance of multiple separate advances under the Option 2 Pricing Period at June 30, 2025 and December 31, 2024;

(b)the expected probability of the draws on the SEPA, which we estimate based on our expectation of the draws being completed; and

(c)risk-free interest rate, which was determined by reference to the U.S. Treasury yield curve for time periods commensurate with the expected term of the agreement in relation to the date of the expected draw.

These estimates may be subjective in nature and involve uncertainties and matters of judgment and therefore cannot be determined with exact precision.

(13) Debt

On April 30, 2024 (the "OrbiMed Closing Date"), we entered into the Credit Agreement with OrbiMed, a healthcare investment firm, and certain of its affiliates to support the execution of strategic expansion plans, fuel continued growth, and provide financial flexibility.

Pursuant to the Agreement, OrbiMed agreed to provide a term loan facility to the borrower, in an aggregate principal amount of $50.0 million, as follows:

a.$25.0 million funded on the OrbiMed Closing Date (the “Initial Term Loan”).

b.$10.0 million term loan available at the election of the borrower, provided that Product Revenue Base (defined below) for the trailing 12-months ending on the last day of the month immediately prior to the funding of such loan was at least $30.0 million (the “First Delayed Draw Term Loan Commitment”). The First Delayed Draw Term Loan Commitment expires on June 30, 2025.

c.An additional $15.0 million term loan available at the election of the borrower, provided that Product Revenue Base (defined below) for the trailing 12-months ending on the last day of the month immediately prior to the funding of such loan was at least $50.0 million (the “Second Delayed Draw Term Loan Commitment” and together with the First Delayed Draw Term Loan Commitment the “DDTL Commitments”). The Second Delayed Draw Term Loan Commitment expires on December 31, 2025.

The term loan will mature on April 30, 2029. On April 30, 2024, we borrowed the initial commitment amount, resulting in gross proceeds of $25.0 million. On February 18, 2025, we borrowed the First Delayed Draw Term Loan Commitment resulting in gross proceeds of $10.0 million based on achieving the trailing 12-month Product Revenue Base of $30.0 million in January 2025.

The Credit Agreement includes a subjective acceleration clause whereby an event of default, including a material adverse change in the business, operations, or conditions (financial or otherwise), could result in the acceleration of the obligations under the Credit Agreement. Under certain circumstances, a default interest rate of an additional 4.0% per annum will apply, at the election of OrbiMed, on all outstanding obligations during the occurrence and continuance of an event of default. OrbiMed can also declare all or a portion of the outstanding principal amount of the loan due and payable, and cancel any unmade draws. OrbiMed has not exercised its right under this clause, as there have been no such events.

As part of the First Amendment To Credit Agreement and Registration Rights Agreement, effective March 20, 2025, we received a waiver for the prior default events related to the Series A Convertible Preferred Stock conversions and the Agreement was amended to allow for these conversions going forward. In addition, we received a waiver on March 31, 2025 to extend the timing for the required audited financial statements to occur on or before April 15, 2025. Effective on April 30, 2025, the Second Amendment To Credit Agreement allows for the Company accelerate payment of the Series A Preferred Stock dividends in cash payments in lieu of fractional shares upon conversion of the Preferred Stock shares.

Repayment

Table of Contents

Borrower will start repaying the outstanding principal amount of the Term Loans. Such repayments will commence in the calendar month immediately following the applicable Test Date (stipulated in the table below) and occur on the last day of each calendar month ("Amortization Payment Date"). The repayments are made in equal monthly installments, calculated from the first Amortization Payment Date through the Maturity Date and the balance principal amount of the Term Loans shall be repaid on the Maturity Date. The repayments include the applicable Repayment Premium and the Exit Fee (each as defined below). The repayment of the Term Loans as aforementioned, is referred to as the “Revenue Base Redemption Feature.”


Test Dates (fiscal Quarter Ending)			Product Revenue Base for 12 months Period
June 30, 2025			33,400
September 30, 2025			37,800
December 31, 2025			42,700
March 31, 2026			46,400
June 30, 2026 and each Fiscal Quarter ending thereafter			50,000

As of June 30, 2025, we were in compliance with the Product Revenue Base requirement and no repayments were required.

Repayment Premium

All repayments and prepayments of the Term Loans (other than on Maturity Date) shall be accompanied by the payment of the premium, which shall be determined based on the timing of the repayment as follows (the “Repayment Premium”):


Time of Repayment			Premium Rate
Within the first 12 months from the funding date of each respective loan.			3.0% plus the Make-Whole Amount (defined below) (1)
After the first 12 months but before the 24-month anniversary of the funding date of each respective loan.			3.0%
After the 24-month anniversary but before the 36-month anniversary of the funding date of each respective loan.			2.0%
After the 36-month anniversary but before the 48-month anniversary of the funding date of each respective loan.			1.0%
After the 48-month anniversary of the funding date of each respective loan.			0.0%

(1) “Make-Whole Amount” is equal to the sum of the remaining scheduled interest payments through the 12-month anniversary

of the closing date of each respective loan.

Interest Rate and Payment

The interest rate is calculated as Secured Overnight Financing Rate for the interest period (which shall not be less than 4.0% (the “Floor”)) plus 8.5% (the “Interest Rate”). Until the first full interest period after the 15 months anniversary of the OrbiMed Closing Date, 3.5% of the Interest Rate shall be designated as paid-in-kind interest, which is added to the outstanding principal amount of the Loans (the “PIK Interest”). However, the Borrower upon written notice can elect to pay all interest in cash, or to pay a percentage less than 3.5% as PIK Interest.

On and after occurrence of any Event of Default, until such Event of Default is cured, the Borrower is obligated to pay 4.0% in addition to the otherwise applicable Interest Rate (the “Default Rate”).

Interest payments (except PIK Interest) are due on the last day of the month. Whenever a prepayment is made on the principal of the Term Loans, the accrued interest on the amount prepaid is also due on such date.

Debt Related Fees

(1) Exit Fee

The Borrower on the repayment of the Term Loans is obligated to pay an additional fee equal to 4.0% of the of the principal amount being repaid. This applies whether the repayment is made on the Maturity Date, or under any other conditions specified in the Agreement (the “Exit Fee”).

(2) Commitment Fee

Table of Contents

The Borrower on the funding date of the Term Loans, shall pay a commitment fee to the Lender, equal to 2.0% of the principal amount drawn (the “Commitment Fee”).

(3) Undrawn Fee

Every month, the Borrower is obligated to remit a fee to the Lender, calculated as 0.25% per annum of the total undrawn amount under the DDTL Commitments.

(4) Administrative Fee

The Borrower will pay to the Agent for its own account a quarterly loan administration fee of $0.01 million, payable in advance, with the first payment due and payable upon the OrbiMed Closing Date.

Increased Costs

If, at any time, any Lender incurs additional cost, reductions in any sum receivable by the Lender under the Agreement or reduction in the rate of return with respect to the Term Loans because of any change in applicable law or government rule including laws regarding capital adequacy, reserve requirements, taxes, or similar requirements, etc., (collectively, “Yield Adjustment Events”), the Borrower will pay the Lenders an additional amount to compensate the Lender for such increased costs or reduction in rate of return (the “Yield Protection Adjustment Feature”).

Taxes

Unless otherwise required by applicable law, any and all payments shall be made free and clear of and without deduction for any taxes; provided, that if any taxes shall be deducted (as required by law or otherwise) from such payments, then the Borrower or the withholding agent shall be entitled to make such deductions and shall timely pay the full amount deducted to the relevant government authority in accordance with applicable law.

If such taxes are Non-Excluded Taxes (as defined in the Agreement), then the sum payable by the Borrower shall be increased as necessary so that after all required deductions have been made, the Lenders receive an amount equal to the sum it would have received had no such deduction been made (the "Tax Gross-Up Feature”).

Warrant

In connection with the closing of the OrbiMed Credit Agreement, we issued OrbiMed the Initial OrbiMed Warrant. See Note (9) Warrants for further discussion. In addition to issuing the Initial OrbiMed Warrant, on each of the closings of the Delayed Draw Commitment Amounts, if any, we agreed to issue additional warrants to purchase a number of shares of our common stock determined by dividing 5.0% of the applicable Delayed Draw Commitment Amount by the 10-day volume weighted average sale price of our common stock as of the issue date (the “Subsequent OrbiMed Warrant” and collectively, with the Initial OrbiMed Warrant, the “OrbiMed Warrants” and together with the SPAC Warrants, the “Warrants”). The Subsequent OrbiMed Warrants will expire seven years from each applicable issuance date, if any. In connection with the OrbiMed Warrants, we entered into a Registration Rights Agreement with OrbiMed (the “OrbiMed Registration Rights Agreement”), whereby OrbiMed will have certain customary registration rights with respect to the shares of common stock underlying the OrbiMed Warrants. If we fail to comply with certain of our obligations under the OrbiMed Registration Rights Agreement with respect to maintaining an effective registration statement covering shares of Common Stock underlying the OrbiMed Warrants, then the expiration date of an OrbiMed Warrant may be extended.

Additionally, the Initial OrbiMed Warrant is subject to customary price-based anti-dilution protections, such that, in certain circumstances, if we issue shares of our common stock below the current exercise price of the Initial OrbiMed Warrant, the exercise price of the Initial OrbiMed Warrant will be adjusted downward based on such issuance.

Accounting Treatment

In 2024, we recorded the Initial Term Loan and the First Delay Draw as long-term debt, and recorded the costs incurred to obtain the loan as contra-debt, in accordance with ASC 470, Debt. In addition, we determined that the Initial OrbiMed Warrant met the definition of a derivative under ASC 815, Derivatives and Hedging, and should be recorded as a liability, and that we should bifurcate and separately recognize the Revenue Base Redemption Feature (see Notes (4) Financial Instruments and (9) Warrants for further discussion).

During the three months ended June 30, 2025, we recognized interest of $1.2 million related to the Term Loan, of which $0.3 million was recorded as PIK interest. The remaining $0.9 million was paid in cash to OrbiMed. We also expensed $0.2 million of the capitalized debt issuance costs, which was charged to non-cash interest, and we accreted $0.1 million of the exit fee which will be due at the termination of the Initial Term Loan.

(14) Convertible Preferred Stock

Series A Convertible Preferred Stock

At the Closing Date on August 10, 2023, we issued 4,015,002 shares of Series A Convertible Preferred Stock at a purchase price of $10.00 per share for an aggregate purchase price of $40.2 million, pursuant to separate subscription agreements dated June 7, 2023, and July 4, 2023 (collectively, the “Subscription Agreements”).

As of June 30, 2025, we are authorized to issue up to 10,000,000 shares of preferred stock with 6,405,998 shares available for issuance. The original issue price of the Series A Convertible Preferred Stock was $10.00. The Series A Convertible Preferred Stock accrues cumulative dividends at the rate of 8.00% per annum on the original issue price. As of June 30, 2025, total undeclared cumulative dividends were $5.4 million. We have not recorded the undeclared dividends in our condensed consolidated financial statements, except the statement of operations.

All shares of Series A Convertible Preferred Stock had the following rights:

(i)Conversion

(a)Optional Conversion

The Series A Convertible Preferred Stock are convertible at any time at the option of the holder thereof into the number of shares of our Common Stock determined by the quotient of (i) the sum of $10.00 (as adjusted for any stock dividend, stock split, reverse stock split, combination or similar event affecting the Series A Convertible Preferred Stock) (the “Liquidation Preference”) and, if we have not elected to otherwise pay the accrued Annual Dividends (as defined below) in cash to the holder, the accrued Annual Dividends on such shares as of the date of conversion, divided by (ii) the Conversion Price (as defined in our Certificate of Designations, Preferences, and Rights of Series A Convertible Preferred Stock (the "Certificate of Designations")) of such shares in effect at the time of conversion.

(b)Automatic Conversion

On the four-year anniversary of the Closing, all then outstanding shares of Series A Convertible Preferred Stock shall automatically convert into the number of shares of our Common Stock equal to the quotient of (i) the sum of the Liquidation Preference and if we had not elected to otherwise pay the accrued Annual Dividends in cash to the holder, the accrued Annual Dividends on such shares as of the date of conversion, divided by (ii) the Conversion Price of such shares in effect at the time of conversion.

Table of Contents

(ii)Voting Rights

Holders of the Series A Convertible Preferred Stock are entitled to vote with the holders of our Common Stock on all matters submitted to a vote of our stockholders, except as otherwise provided in the Certificate of Designations or as required by applicable law, voting together with the holders of our Common Stock as a single class. Each holder is entitled to a number of votes in respect of the shares of Series A Convertible Preferred Stock owned as of the record date by it, or if no such record date is established, as of the date such vote is taken or any written consent of stockholders is solicited, equal to the quotient of (i) $10.00 divided by (ii) the Minimum Price (as defined in Nasdaq Listing Rule 5635(d)) of our Common Stock as determined at Closing.

As long as any shares of Series A Convertible Preferred Stock are outstanding, we shall not, without the affirmative vote of the Holders of a majority of the then-outstanding shares of the Series A Convertible Preferred Stock, (i) amend, alter, repeal or otherwise modify any provision of our certificate of incorporation or the Certificate of Designations in a manner that would alter or change the terms or the powers, preferences, rights or privileges of the Series A Convertible Preferred Stock as to affect them adversely; (ii) authorize, create, increase the authorized amount of, or issue any class or series of capital stock senior to the Series A Convertible Preferred Stock; (iii) increase the authorized number of shares of Series A Convertible Preferred Stock or enter into any agreement with respect to the foregoing.

(iii)Dividends

Holders of the Series A Convertible Preferred Stock are entitled to participate equally in any dividends declared to holders of Common Stock. In addition, each holder of the Series A Convertible Preferred Stock is entitled to receive cumulative annual dividends that accrue and accumulate daily at a rate per annum (calculated on the basis of an actual 365- or 366-day year, as applicable) equal to 8.00% of the original issue price of $10.00 per share (the "Annual Dividends”). The Annual Dividends will be either paid in cash, paid by issuing fully paid and nonassessable shares of Common Stock, or a combination thereof when, as and if authorized and declared by our Board. Upon conversion or a change of control, any unpaid Annual Dividends will be paid to the holders, either in the form of common stock upon a conversion, or in cash upon a change of control. So long as any shares of Series A Convertible Preferred Stock remain outstanding, unless all Annual Dividends on all outstanding shares of Series A Convertible Preferred Stock have been declared and paid in cash, we will be prohibited from declaring any dividends on, or making any distributions relating to, other classes of our capital stock ranking junior to the Series A Convertible Preferred Stock, subject to certain exceptions.

(iv)Anti-dilution Provisions

The initial Conversion Price of $10.00 is subject to customary adjustments in the case of certain distributions to holders of our Common Stock payable in shares of our Common Stock, subdivisions, splits or combinations of the shares of our Common Stock and distributions to all holders of shares of our Common Stock of any convertible securities or options or any other assets for which there is no corresponding distribution in respect of the Series A Convertible Preferred Stock.

The Conversion Price automatically reset on February 10, 2025 and will automatically reset on July 10, 2027, the eighteen-month and forty-seven-month anniversaries of the Closing Date, to be equal to the lowest of:

(i)Initial Conversion Price, subject to adjustments for stock dividends and distributions or other distributions made to common stockholders for which there is no corresponding distribution for Preferred Stock,

(ii)the then-current Conversion Price, and

(iii)the higher of 1) the Floor Price ($2.10 per share) or 2) the trailing ten-Trading Day VWAP of the Common Stock determined as of the date of such reset.

On February 10, 2025, the Conversion Price was reset to $5.277 based on the trailing ten-trading day VWAP of the Company's common stock.

(iv)Liquidation Preferences

The terms of the Series A Convertible Preferred Stock provide for liquidation preferences in the event of a change in control, liquidation, dissolution, or certain other fundamental transactions of the Company (a “Liquidation Event”), none of which were deemed probable as of June 30, 2025. The Liquidation Preferences of $10.00 per share, plus all unpaid dividends, are payable prior to payment to any class of capital stock that is junior to the Series A Convertible Preferred Stock.

If the assets of the Company or the consideration received in such Liquidation Event are insufficient to make payment of the full Liquidation Preferences to all holders of Series A Convertible Preferred Stock, then such assets will be distributed ratably to the holders of Series A Convertible Preferred Stock in proportion to the full amounts to which

Table of Contents

they would otherwise have been entitled. After payment of the aforementioned Liquidation Preferences, any remaining proceeds from a Liquidation Event will be distributed to all classes of capital stock that are junior to the Series A Convertible Preferred Stock pro rata on an as-if converted basis.

The following table summarizes activity in Series A Convertible Preferred Stock, if-converted, in the six months ended June 30, 2025.


Series	Balance at December 31, 2024	Issuances	Retirements / Conversions	Balance at June 30, 2025
Series A convertible preferred stock (assuming maximum conversion)	25,048,584	—	(2,457,715)	22,590,869
Total convertible preferred stock	25,048,584	—	(2,457,715)	22,590,869

On June 23, 2025, we commenced an offer (the “Offer”) to all holders of preferred stock shares to receive 3.3 shares of common stock of the Company in exchange for each preferred stock share tendered by the holder and exchanged pursuant to the Offer. The Offer expired at one minute after 11:59 p.m., Eastern Daylight Time, on July 23, 2025. We were advised that approximately 98.8% of the outstanding shares of preferred stock shares were validly tendered through the Offer and not withdrawn prior to the Expiration Date, and were accepted for exchange. Including the remaining preferred stock shares not tendered through the Offer, all preferred stock shares were converted for common stock shares on July 31, 2025, resulting in the issuance of 11,813,059 common stock shares.

(15) Net Loss Per Share

Basic net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. During periods where we might earn net income, we would allocate to participating securities a proportional share of net income determined by dividing total weighted-average participating securities by the sum of the total weighted-average common shares and participating securities (the “two-class method”). Our preferred stock participates in any dividends declared, if any, by us and are therefore considered to be participating securities. Participating securities have the effect of diluting both basic and diluted earnings per share during periods of income. During periods where we incurred net losses, we allocate no loss to participating securities because they have no contractual obligation to share in our losses. We computed diluted loss per common share after giving consideration to the dilutive effect of stock options and warrants that are outstanding during the period, except where such nonparticipating securities would be antidilutive. Because we have reported net losses for the six months ended June 30, 2025 and 2024, diluted net loss per common share is the same as basic net loss per common share for those periods.

The following potentially dilutive securities (in common stock equivalent shares) have been excluded from the computation of diluted weighted-average shares outstanding because such securities have an antidilutive impact due to losses reported:


	June 30,
	2025	2024
Preferred stock	22,590,869	25,237,155

Common stock warrants	7,402,541	14,345,917
RSUs and PSUs	671,803	544,988
Options to purchase common stock	5,434,039	4,866,070
Shares issuable under the SEPA	3,468,998	4,510,704
Total	39,568,250	49,504,834

As a result of the Offer related to the Preferred Stock, the Preferred Stock will be completely converted to Common Stock before the quarter-end September 30, 2025 and will no longer be considered a potentially dilutive security. See Note (14) Convertible Preferred Stock for further details.

(16) Share-Based Compensation

We currently maintain the 2023 Equity Incentive Plan (the “2023 Plan”), which our Board of Directors and stockholders approved in connection with the Business Combination, for purposes of granting equity-based incentive awards to our employees and consultants, including our executive officers and directors. Prior to the Business Combination, TriSalus granted equity incentive awards under the 2009 Amended and Restated Equity Incentive Plan (the “2009 Plan”). The 2009 Plan has not be used following the Business Combination. However, any awards granted under the 2009 Plan remain subject to the terms of the 2009 Plan and the applicable award agreement. Historically, we have used options as an incentive for long-term compensation to our executive officers because options allow our executive officers to realize value from this form of equity compensation only if the value of the underlying equity

Table of Contents

securities increase relative to the option’s exercise price, which exercise price is set at the fair market value of the underlying equity securities on the grant date.

The 2009 Plan and the 2023 Plan are administered by our chief executive officer and chief financial officer, who act on the recommendation of managers of the Company to select the individuals to whom the awards will be granted and to determine the amount and vesting period for the grants. All grants are subject to approval by the board of directors.

As of June 30, 2025, the balances under the two plans are below.


	June 30, 2025
	Authorized	Outstanding	Available for Issue
2009 Plan	1,206,450	1,206,450	—
2023 Plan	10,077,467	4,899,392	5,178,075
Total	11,283,917	6,105,842	5,178,075

2009 Equity Incentive Plan

As of June 30, 2025, there were in total 1,172,771 stock options and 33,679 RSUs issued and outstanding under the 2009 Plan. Stock options were granted with an exercise price equal to the estimated fair value of the stock at the date of grant. Prior to the Business Combination, the fair value was determined by a third-party valuation performed in accordance with IRS Section 409A. No awards have been granted subsequent to the Business Combination, as the 2009 Plan was frozen and replaced by the 2023 Plan (see below). Options generally have a ten-year contractual term and typically have graded vesting over one to four years.

As of June 30, 2025, we had unrecognized compensation expense of $0.4 million and $0.2 million, respectively, for options and RSUs granted under the 2009 Plan. The June 30, 2025 balance will be recognized over a weighted average period of 0.9 years.

2023 Equity Incentive Plan

As of June 30, 2025, there were in total 4,261,268 stock options and 638,124 RSUs and PSUs issued and outstanding under the 2023 Plan. Under the 2023 Plan, the Company’s Board may grant equity-based incentive awards to employees, consultants and other service providers of the Company and its affiliates within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended. Initially, 5,585,008 shares were authorized under the 2023 Plan. In addition, the share reserve will automatically increase on January 1 of each year for a period of 10 years, commencing on January 1, 2024, and ending on January 1, 2033, in an amount equal to (1) five percent of the total number of shares of the fully diluted Common Stock determined on December 31 of the preceding year, or (2) a lesser number of shares of Common Stock determined by our Board prior to January 1 of a given year. On January 1, 2025, the authorized shares under the 2023 Plan increased by 2,383,545 shares to 10,350,022. Options for 45,167 shares of Common Stock were exercised during the six months ended June 30, 2025. During the six months ended June 30, 2025, we granted 1,282,314 options with a weighted average fair value of $5.30, and 487,546 restricted stock units, net of forfeitures, with a weighted average fair value of $5.32.

As of June 30, 2025, we had unrecognized compensation expense of $10.7 million and $3.6 million, respectively, for options and RSUs & PSUs granted under the 2023 Plan. The balance at June 30, 2025, will be recognized over a weighted average period of 2.7 years.

Our Board, or a duly authorized committee thereof, administers the 2023 Plan. Our Board may also delegate to one or more of our officers the authority to, among other things, (1) designate employees (other than officers) to receive specified stock awards and (2) determine the number of shares subject to such stock awards. Under the 2023 Plan, the Board has the authority to determine award recipients, grant dates, the numbers and types of stock awards to be granted, the applicable fair market value and exercise price, and the provisions of each stock award, including the exercise period and the vesting schedule applicable to a stock award, subject to the limitations of the 2023 Plan.

Stock options are granted with an exercise price no less than 100% of the estimated fair value of a share of Common Stock at the date of grant.

Employee Stock Purchase Plan

We maintain an Employee Stock Purchase Plan ("ESPP"), which provides our eligible employees with an opportunity to purchase shares of Common Stock, to assist us in retaining the services of eligible employees, to secure and retain the services of new employees and to provide incentives for such persons to exert maximum efforts for our success. The ESPP became active in 2024. Initially, 2,350,530 shares of Common Stock were reserved for issuance

Table of Contents

under the ESPP. The number of shares of Common Stock reserved for issuance under the ESPP will automatically increase on January 1 of each year for a period of up to ten years, beginning on January 1, 2024, and continuing through and including January 1, 2033, by an amount equal to the lesser of (a) two percent (2%) of the total number of shares of the Fully Diluted Common Stock determined on December 31 of the preceding year, and (b) 200% of the Initial Share Reserve. On January 1, 2025, the authorized shares under ESPP increased by 953,418 shares to 3,303,948

During the six months ended June 30, 2025, 49,939 shares were purchased in an offering under the ESPP.

(17) Commitments And Contingencies

From time to time, we may have certain contingent liabilities, including litigation, which arise in the ordinary course of its business activities. We accrue contingent liabilities when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. In the opinion of management, there are no pending claims for which the outcome is expected to result in a material adverse effect on our condensed consolidated financial position, results of operations, or cash flows.

As part of the Business Combination, we entered into the Amended and Restated Registration Rights Agreement with certain investors in MedTech and Legacy TriSalus. Subject to certain requirements and customary conditions, we granted piggyback registration rights and demand registration rights to the parties thereto, agreed to pay certain expenses related to such registrations and agreed to indemnify the parties thereto against certain liabilities related to such registrations. Our registration obligations under the Amended and Restated Registration Rights Agreement will terminate with respect to any party thereto on the date that such party no longer holds any Registrable Securities (as defined in the Amended and Restated Registration Rights Agreement). The Amended and Restated Registration Rights Agreement does not contain liquidated damages or other cash settlement provisions resulting from delays in registering the Company’s securities.

We are not a party to any legal proceedings, and we are not aware of any claims or actions pending or threatened against us. In the future, we might from time to time become involved in litigation relating to claims arising from our ordinary course of business.

(18) Leases

We have two property leases in effect as of June 30, 2025, which we account for as operating leases:

•A lease for our principal administrative and production facility at 6272 West 91st Avenue, Westminster, Colorado, which expires on December 31, 2031. This lease includes one option to extend the lease by five years from the end of the then current term.

•A lease for office space at 2275 Half Day Road, Bannockburn, Illinois, which expires in January 2028. This lease includes an option to extend the lease by three years at the end of the current term.

We also have two finance leases for copier equipment in our Westminster and Bannockburn facilities.

On July 17, 2024, we exercised one of the two options to extend the current lease for the Westminster facility for an additional period of five years commencing on January 1, 2027, and ending on December 31, 2031 ("Second Extended Lease Term"). All terms and conditions of the lease shall continue to apply during the Second Extended Lease Term. We will pay approximately $1.5 million in rent over the duration of the Second Extended Lease Term.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited interim condensed consolidated financial statements and the related notes thereto included elsewhere in this Quarterly Report on Form 10-Q ("Quarterly Report") and for our audited financial statements and related notes thereto as of and for the year ended December 31, 2024 included in our Annual Report on Form 10-K, filed with the Securities and Exchange Commission (“SEC”), on April 15, 2025 ("Annual Report"). Information included in this Form 10-Q, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. For a complete discussion of forward-looking statements, see the section above entitled “Special Note Regarding Forward Looking Statements.” As a result of many factors, including those factors set forth in the section captioned “Item 1A. Risk Factors” of our Annual Report, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis. You should carefully read the “Risk Factors” section of our Annual Report to gain an understanding of the various factors that could cause actual results to differ materially from our forward-looking statements.

For purposes of this discussion, “TriSalus,” “the Company,” “we,” “us” or “our” refer to TriSalus Life Sciences, Inc. (which changed its name to TriSalus Operating Life Sciences, Inc. in connection with the Business Combination) and its subsidiaries prior to the consummation of the Business Combination and TriSalus Life Sciences, Inc. (formerly known as MedTech Acquisition Corporation) after the consummation of the Business Combination, unless the context otherwise requires.

Overview

We are a growing, oncology focused medical technology business seeking to transform outcomes for patients with solid tumors by integrating our innovative delivery technology with standard-of-care therapies, and with our investigational immunotherapeutic, nelitolimod, a class C Toll-like receptor 9 (“TLR9”) agonist, for a range of different therapeutic and technology applications. Our ultimate goal is to transform the treatment paradigm for patients battling solid tumors. We have developed an innovative technology designed to overcome two significant challenges that prevent optimal delivery and performance of therapeutics in these difficult-to-treat diseases: (i) high intratumoral pressure caused by tumor growth and collapsed vasculature restricting the delivery of oncology therapeutics and (ii) off target delivery. Nelitolimod, specifically, combined with our technology, aims to address the immunosuppressive properties of immune cells in the tumor and tumor microenvironment of the liver, pancreas and other solid tumors. By systematically addressing these barriers, we aim to improve response to therapies and to enable improved patient outcomes.

We market our cutting-edge Pressure Enabled Drug Delivery (PEDD™) infusion systems, which optimize delivery of embolics and therapeutics for the treatment of various solid tumors. Additionally, we have conducted Phase I clinical trials of nelitolimod to study the ability of an immunotherapeutic--when administered via PEDD in combination with systemic treatment--can enhance the effectiveness of other therapeutics and ultimately lead to better patient responses. Once final data is assembled, we plan to pursue a pharmaceutical partner for future development. We believe the combination of our PEDD technology with nelitolimod has the potential to solve two main barriers in the tumor microenvironment that inhibits the success of immunotherapy. The first barrier (mechanical) is comprised of high intratumoral pressure within tumors that limits drug uptake and the second barrier (biological) is the reversal of intratumoral immunosuppression.

In 2020, we launched TriNav™, our therapeutic and embolic delivery device with SmartValve technology for our proprietary PEDD approach. Current sales consist of the TriNav Infusion System, introduced in 2020. In 2020, we gained transitional pass-through payments (“TPT”) approval from the Centers for Medicare & Medicaid Services (“CMS”), which allows hospitals to cover the cost of using TriNav. The approval began in January 2020 and expired at the end of 2023. On December 14, 2023, CMS created a permanent New Technology Healthcare Common Procedure Coding System (HCPCS) code for procedures involving the TriNav® Infusion System. This code became effective on January 1, 2024, and may be reported by hospital outpatient departments (HOPDs) and ambulatory surgical centers (ASCs) for the Company to obtain reimbursement for TriNav device. Effective April 1, 2025, TriNav received a second unique and permanent HCPCS code from CMS. This new code provides reimbursement clarity for mapping procedures conducted prior to transarterial radioembolization ("TARE").

In 2024, we expanded our portfolio of PEDD devices with the launch of the TriNav LV Infusion System and TriGuide Guiding Catheter to optimize therapeutic delivery for patients with larger vessels. The TriNav LV is targeted for patients with vessels sized between 3.5 and 5.0mm and is expected to provide a full range of PEDD devices for all vessel sizes and allow us to expand our addressable liver embolization market. The TriGuide Guiding Catheter has a larger inner diameter, lubricious inner lining, and reverse curve design to support femoral access for the TriNav LV, which we believe will enhance procedural efficiency. In June 2025, we launched an additional PEDD device, TriNav

FLX, designed with a more flexible distal tip to facilitate navigation through tortuous anatomy. These new products are eligible for the same HCPCS reimbursement codes as existing TriNav products, enabling seamless integration into current billing structures. In the second quarter of this year,

We also initiated a registry study called PROTECT (Pressure Enabled Retrograde Occlusive Therapy with Embolization for Control of Thyroid Disease) and intends to enroll 100 patients across ten leading academic sites. It is estimated that approximately 5% of adults have multinodular goiters, and the prevalence in adults over 50 is estimated to be up to 50%. We estimate that this could expand the addressable market by approximately 50,000 procedures, representing an incremental $400.0 million market opportunity. This new procedure utilizing the TriNav system is also eligible for the same Healthcare Common Procedure Coding System (HCPCS) reimbursement code allowing for seamless integration into current billing approaches.

We are a high growth, high margin company approaching a level of revenues that can generate sufficient cash flow to sustain our operations. Beginning in 2020, our mission was to improve the delivery of therapeutics to solid tumors across a range of different diseases and tumor types. Additionally, we acquired an immune-oncology drug, nelitolimod, in July 2020, and conducted several Phase I clinical trials to study the ability and value of our PEDD technology. We have completed Phase I dose escalation (UMLM and LA-PDAC) and Phase Ib (ICC/HCC) clinical trials for nelitolimod. Due to physician and investigator interest, we are supporting two IIT studies, one in patients with advanced HCC in combination with durvalumab and tremelimumab and another in patients with resectable colorectal liver metastases. Based on the changing landscape for second line treatment of uveal melanoma, we do not intend to proceed to Phase II trials for that indication on our own, but we are looking for potential partners to advance that indication. Our PERIO-03 Phase I dose escalation in LA-PDAC has completed enrollment and we anticipate data from the study will be available sometime in 2025, and will begin discussions for a pharmaceutical partner for further clinical development.

Factors Affecting Our Performance

We believe that our performance and future success depend on several factors that present significant opportunities for us but also pose risks and challenges, including those discussed below and in the section of the Annual Report titled “Risk Factors.” In particular, our performance is affected by:

•The continued acceptance and growth of TriNav in the marketplace. While we believe TriNav to be a superior technology for the delivery of therapies to tumors, particularly high-density tumors, there are other technologies with which we compete. Our ability to increase TriNav sales depends on the skills of our sales force and the willingness of the marketplace to use TriNav.

•Our ability to maintain our current TriNav pricing and gross margins to help fund the rest of our activities. Our current pricing allows us to generate a substantial gross margin, which provides funds to support our growth and our research and development (“R&D”) for both TriNav and nelitolimod. TriNav sells at a significant premium to competitive products. Our higher price was previously supported by the TPT payment program from CMS; however, the TPT authorization expired on December 31, 2023. In December 2023, CMS granted a New Technology HCPCS for both mapping and therapeutic procedures involving TriNav. This code, HCPCS C9797, has been assigned to the Ambulatory Payment Classification (APC) 5194 - Level 4 Endovascular Procedures. The code became effective on January 1, 2024, and may be reported by hospital outpatient departments and ambulatory surgical centers, but there can be no assurance that continuing reimbursement will be available at similar reimbursement rates or at all. Effective April 1, 2025, TriNav received a second unique and permanent HCPCS code from CMS, C8004, which has been assigned to APC 5193 (Level 3 Endovascular Procedures). This new code provides reimbursement clarity for mapping procedures conducted prior to TARE. Any reduction in the amount of the reimbursement for TriNav will negatively impact the revenue we are able to generate from the sale of TriNav and may hinder our ability to recoup our total investment in TriNav notwithstanding regulatory approval of the product. If we are unable to promptly obtain coverage and profitable payment rates from hospital budgets or government-funded and private purchasers for TriNav or any future products, we may sell fewer units or need to sell them at a lower price. Such changes in revenues would have a material adverse effect on our operating results and our overall financial condition.

•The success and cost of our clinical trials of nelitolimod. Nelitolimod is in Phase I human trials to determine if, when delivered via TriNav, it is safe and effective in treating certain cancers. As with all drug candidates, the cost of operating clinical trials can be substantial, with no guarantee that the trials will result in favorable data.

•Obtaining FDA approval of nelitolimod for sale. Our clinical trials are still in early stages, and there is no certainty that we will generate favorable data or that, upon review, the FDA will approve nelitolimod for sale.

Recent Developments

April 2025 Securities Purchase Agreement

In April 2025, we entered into a securities purchase agreement (the “Purchase Agreement”) with certain institutional and accredited investors named therein (the “Purchasers”) pursuant to which the Company agreed to issue and sell to the Purchasers in a private placement (the “Private Placement”) an aggregate of 5,500,000 shares (the “Shares”) of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), at a purchase price of $4.00 per share.

The Purchase Agreement contains customary representations, warranties and agreements by the Company and the Purchasers, indemnification rights and other obligations of the parties. In connection with the Private Placement, the Company and the Purchasers entered into a registration rights agreement (the “Registration Rights Agreement”) at the closing, pursuant to which the Company granted certain registration rights to the Purchasers with respect to their Shares (as further described below). In addition, the Company committed to use commercially reasonable efforts to satisfy all of its obligations set forth in the Support Agreements (as defined below). The Company and its directors and officers have agreed, for a period of 60 days after the date of the Purchase Agreement, to customary lock-up and clear market provisions, as applicable, subject to certain exceptions.

The Private Placement closed on May 2, 2025. The Company received aggregate gross proceeds from the Private Placement of approximately $22.0 million, before deducting estimated offering fees and expenses payable by the Company.

Series A Convertible Preferred Stock

On June 23, 2025, we commenced an offer (the “Offer”) to all holders of preferred stock shares to receive 3.3 shares of common stock of the Company in exchange for each preferred stock share tendered by the holder and exchanged pursuant to the Offer. The Offer expired at one minute after 11:59 p.m., Eastern Daylight Time, on July 23, 2025. We were advised that approximately 98.8% of the outstanding shares of preferred stock shares were validly tendered and not withdrawn prior to the Expiration Date, and were accepted for exchange. Including the remaining preferred stock shares not tendered through the Offer, all preferred stock shares were converted on July 31, 2025, resulting in the issuance of 11,813,059 common stock shares.

One Big Beautiful Bill Act

On July 04, 2025, the “One Big Beautiful Bill Act” (the “Act”) was enacted into law. The Act has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. These changes include the allowance of immediate expensing of qualifying research and development expenses and permanent extension of certain provisions within the Tax Cuts and Jobs Act. We are in the process of evaluating the impact of the Act to our condensed consolidated financial statements.

Components of Results of Operations

The following discussion sets forth certain components of our Condensed Consolidated Statements of Operations as well as factors that impact those items.

Revenue

We currently operate in one reportable segment and revenue is generated primarily from sales of PEDD infusion systems to our customers, principally related to TriNav. Revenue is recognized when control of the promised goods or services is transferred to the customer in an amount that reflects the consideration to which we expect to be entitled in exchange for those products or services.

The primary end-user customers for our products are hospitals, clinics, and physicians, to which we sell directly.

Cost of Goods Sold

Cost of goods sold primarily consists of raw materials, direct labor, manufacturing overhead and depreciation costs related to production of TriNav.

Table of Contents

Gross Profit and Gross Margin

Gross profit represents revenue less cost of goods sold. Gross margin is gross profit expressed as a percentage of revenue. Our gross margin and overall profitability may in the future fluctuate from period to period based on a number of factors, such as the innovation initiatives we undertake, and manufacturing costs and efficiencies.

Operating Expenses

Our operating expenses consist of R&D, sales and marketing and general and administrative expenses.

Research and Development

R&D expenses include engineering, regulatory, pre-clinical and clinical activities, including salaries, travel, materials purchased for R&D activities and patent expense. We expense R&D costs as incurred. We recognize expenses for certain development activities, such as preclinical studies and manufacturing, based on an evaluation of the progress to completion of specific tasks using data or other information provided to us by our vendors. Payments for these activities are based on the terms of the individual agreements, which may differ from the pattern of expenses incurred. Non-refundable advance payments for goods or services to be received in the future for use in R&D activities are recorded as prepaid expenses. These amounts are recognized as an expense as the goods are delivered or the related services are performed, or until it is no longer expected that the goods will be delivered, or the services rendered.

Sales and Marketing

Sales and marketing expense consists primarily of salaries, commissions, travel and related business expenses for our sales force, which is principally engaged in physician education regarding the features and benefits of TriNav. We also incur expenses for attendance at medical society meetings, product promotions and marketing activities.

General and Administrative

General and administrative expense includes executive management, finance, information technology, human resources, business development, legal, one-time costs associated with the Business Combination, and the administrative and professional costs associated with those activities. General and administrative costs also include corporate facility costs, including rent, utilities, depreciation and maintenance, not otherwise included in production or R&D expenses, as well as regulatory and professional fees for legal, patent, accounting and other consulting services. We also record public company costs in general and administrative, including board expenses, insurance, audit fees, NASDAQ fees, and costs associated with public company financial reporting.

Change in Fair Value of SEPA, Warrant, and Revenue Base Redemption Liabilities

Change in fair value of SEPA, Warrant, and Revenue Base Redemption liabilities represents the change in fair value at each reporting period of the SEPA, the change in fair value of the SPAC Warrants we assumed in the Business Combination, and the change in fair value of the OrbiMed Warrants issued in connection with the initial and subsequent draw down under the OrbiMed Credit Agreement.

Change in Fair Value of Contingent Earnout Liability

Change in fair value of contingent earnout liability represents the change recorded as a result of remeasurement of the fair value.

Income Tax Expense

Our income tax provision consists primarily of U.S. federal and state income taxes. We maintain a full valuation allowance for our federal and state deferred tax assets, including net operating loss carryforwards, as we have concluded that it is not more likely than not that the deferred tax assets will be realized.

Comparison of the Three Months Ended June 30, 2025, and 2024

Revenue

Revenue increased by $3.8 million, or 52.3% for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The increase in revenue was due to a 52.5% increase based on the units of TriNav sold and the introduction of a price increase.

Cost of Goods Sold and Gross Profit

Cost of goods sold increased by $0.9 million, or 97.6% for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The increase in cost of goods sold was primarily due to higher production volumes to support our increased revenue.

Gross profit increased by $3.0 million, or 45.9% for the three months ended June 30, 2025, and gross margin decreased to 83.9% from 87.6% for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The increase in gross profit was due primarily to the increase in sales volume. The year-over-year decline in gross margin was primarily driven by lower manufacturing efficiency associated with newly launched products, a dynamic we expect to improve as production scales and processes mature over the course of the year.

Operating Expenses

Research and Development

R&D expenses decreased by $0.7 million, or 15.9% for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The decrease was primarily driven by a $0.7 million reduction of clinical trial expenses related to nelitolimod.

Sales and Marketing

Sales and marketing expenses increased by $1.2 million, or 19.3% for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The changes was due primarily to a $0.8 million increase in the sales and marketing department headcount and a $0.2 million increase in utilizing consultants during the three months ended June 30, 2025 compared to the same period in the prior year.

General and Administrative

General and administrative expenses increased by $1.7 million, or 43.0%, for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The increase was primarily due to professional services as a result of the timing of various filing and audit related expenses.

Interest Expense

Interest expense increased by $0.5 million for the three months ended June 30, 2025, as compared to the three months ended June 30, 2024. The increase was due to our usage of the OrbiMed Credit Agreement throughout the three months ended June 30, 2025 compared to the prior year period as we entered into the OrbiMed Credit Agreement on April 30, 2024.

Change in Fair Value of the SEPA, Warrant, and Revenue Base Redemption Liabilities

The fair value of the SEPA, warrant, and revenue base redemption liabilities resulted in a change of $8.7 million as a result of a loss of $0.3 million in the three months ended June 30, 2025, compared to a loss of $9.0 million in the three months ended June 30, 2024. The change was primarily due to the increase of the warrant price on the open market and the additions of the Subsequent OrbiMed Warrant as a result of the First Delayed Draw.

Change in Fair Value of Contingent Earnout Liability

The fair value of earnout liability resulted in a change of $13.0 million as a result of a gain of $0.7 million in the three months ended June 30, 2025, compared to a gain of $13.7 million for the three months ended June 30, 2024. This is mainly due to the change in the market price of the underlying common stock.

Comparison of the Six Months Ended June 30, 2025 and 2024

Revenue

Revenue increased by $6.6 million, or 47.5% for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. The increase in revenue was due to a 48.4% increase based on the units of TriNav sold and the introduction of a price increase effective March 1, 2025.

Cost of Goods Sold and Gross Profit

Cost of goods sold increased by $1.4 million, or 75.1% for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024. The increase in cost of goods sold was primarily due to higher production volumes to support our increased revenue.

The increase in gross profit was due primarily to the increase in sales volume. The year-over-year decline in gross margin was primarily driven by lower manufacturing efficiency associated with lower production volumes for a planned shut down during the current period.

Operating Expenses

Research and Development

R&D expenses decreased by $3.3 million, or 31.3% for the six months ended June 30, 2025, as compared to the six months ended June 30, 2024.

Liquidity and Capital Resources

Overview

Since inception, we have incurred significant net losses and expect to continue to incur net losses for the foreseeable future due to the investments we will continue to make in R&D and sales and marketing, and due to additional general and administrative costs we expect to incur as a public company. We incurred net losses of $18.7 million for the six months ended June 30, 2025. We had cash and cash equivalents of approximately $26.5 million at June 30, 2025. Since inception, we have financed operations primarily through the issuance and sales of common and preferred stock, convertible notes, and term loans. We are still in our early stages of development and have yet to generate revenues sufficient to fund cash flows from operations. Our ability to fund future operations and execute our long-term business plan and strategy will require that we raise additional capital. There can be no assurance that we will be able to raise such additional capital on satisfactory terms, if at all. If additional capital is not secured when required, we may need to delay or curtail our operations until such funding is received.

During the six months ended June 30, 2025, we achieved the trailing 12-month Product Revenue Base of $30.0 million in January 2025 and were able to borrow the First Delayed Draw Term Loan Commitment resulting in gross proceeds of $10.0 million. As of June 30, 2025, the minimum cash requirement increased from $5.0 million to $10.0 million. On April 30, 2025, we raised gross proceeds of approximately $22.0 million through a Private Placement. Although these events have occurred, our existing cash and cash equivalents may not be sufficient to fund our projected liquidity requirements for at least the next 12 months from the date of this Quarterly Report, as the adequacy of available funds will depend on many factors, including those described in the section titled “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024. See also “Funding Requirements” below.

Cash Flows

Comparison of the Six Months Ended June 30, 2025, and June 30, 2024

The following table presents net cash from operating, investing, and financing activities (in thousands):


	Six Months Ended June 30,
	2025		2024
Net cash used in operating activities	$	(11,819)	$	(24,289)
Net cash used in investing activities	(621)		(126)
Net cash provided by financing activities	30,405		29,119
Increase in cash, cash equivalents and restricted cash	$	17,965	$	4,704

Cash Used in Operating Activities

For the six months ended June 30, 2025, net cash used in operating activities was $11.8 million. The net cash used in operating activities consisted of net loss of $18.7 million, adjusted for non-cash charges totaling $6.6 million, primarily related to a loss on share-based compensation of $3.5 million, warrant and SEPA liabilities of $1.3 million, and debt expenses of $1.1 million related to paid-in-kind interest and amortization of debt issuance costs. The change in net operating assets and liabilities decreased $0.2 million, due primarily to a decrease in prepaid expenses offset by an increase in accounts receivable.

For the six months ended June 30, 2024, net cash used in operating activities was $24.3 million. The net cash used in operating activities consisted of net loss of $17.5 million, adjusted for non-cash charges totaling $0.2 million, primarily related to a loss on the adjustment of the fair value of the warrants to purchase preferred stock of $6.9 million, depreciation and amortization of $0.4 million and stock-based compensation expense of $2.4 million, partially offset a gain from the change in fair value of contingent earnout liability of $9.7 million. In addition, net operating assets and liabilities decreased $6.9 million driven by an increase in accounts payable and accrued liabilities, an increase in prepaid expenses, and an increase in accounts receivable.

Cash Used in Investing Activities

Net cash used in investing activities of $0.6 million for the six months ended June 30, 2025, was primarily due to purchases of property and equipment of $0.7 million.

Cash Provided by Financing Activities

Net cash provided by financing activities of $30.4 million for the six months ended June 30, 2025, consisted of primarily of $20.5 million, net of expenses, from the April 30, 2025 Private Placement and $9.5 million, net of expenses, from the First Delayed draw under the OrbiMed Credit Agreement.

Table of Contents

Net cash provided by financing activities of $29.1 million for the six months ended June 30, 2024, consisted $6.7 million from the sale of 750,000 shares of common stock under the SEPA and $22.4 million, net of expenses, from the initial draw down under the OrbiMed Credit Agreement.

Funding Requirements

Our primary use of cash is to fund our operating expenses, which consist of sales and marketing expenses related to the growth of our sole commercial product TriNav, research, development and clinical expenses related primarily to TriNav and, to a lesser extent, nelitolimod, as well as general and administrative expenses. If we obtain approval for our product candidates, we expect to incur commercialization expenses, which may be significant, related to establishing or expanding sales, marketing, manufacturing capabilities, distribution and other commercial infrastructure to commercialize such products. Accordingly, we will need to obtain substantial additional funding in connection with our continuing operations. Inflation and rising interest rates may result in an economic recession globally or in the U.S., which could lead to a reduction in product demand, a decrease in corporate capital expenditures, prolonged unemployment, labor shortages, reduction in consumer confidence, adverse geopolitical and macroeconomic events, or any similar negative economic condition. Economic conditions in some parts of the world have been worsening, with disruptions to, and volatility and uncertainty in, the credit and financial markets in the U.S. and worldwide resulting from the effects of inflation and rising interest rates. These conditions have been further exacerbated by recent and potential future disruptions in access to bank deposits or lending commitments due to bank failures, the war in Ukraine and conflicts in the Middle East. It is not possible at this time to estimate the long-term impact that these and related events could have on our business, as the impact will depend on future developments, which are highly uncertain and cannot be predicted. If these conditions persist and deepen, we could experience an inability to access additional capital, or our liquidity could otherwise be impacted. If we are unable to raise capital when needed and on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs and/or other efforts.

We also expect to continue to incur significant expenses in connection with our ongoing activities related to TriNav, including sales and marketing expenses to support our expected sales growth. Our future capital requirements, both near and long-term, will depend on many factors, including but not limited to: the success of our commercialization of TriNav including, among other things, continued patient and physician adoption of TriNav and our ability to maintain adequate reimbursement for TriNav; the cost of commercialization activities for TriNav, including manufacturing, distribution, marketing and sales; net product revenues received from sales of TriNav; the outcome, timing and cost of the regulatory approval process for nelitolimod by the FDA, including the potential for the FDA to require that we perform more studies and clinical trials than those that we currently expect; our ability to draw the remaining $15.0 million available under the OrbiMed Credit Agreement if and when needed; the costs involved in preparing, filing and prosecuting patent applications and annuity fees relating to issued patents; the cost of maintaining and enforcing our intellectual property rights, as well as the cost of defending intellectual property disputes, including patent infringement actions brought by third parties against us; the initiation, progress, timing, costs and results of clinical trials and other research and development related to our product candidates; and the extent to which we in-license, acquire or otherwise partner in development or commercialization of other products, product candidates or technologies; the achievement of milestones or occurrence of other developments that trigger payments under the Dynavax Agreement or any other collaboration or other agreements; the number of future product candidates that we may pursue and their development requirements; the costs of commercialization activities for any of our product candidates that may receive marketing approval to the extent such costs are not the responsibility of any future collaborators, including the costs and timing of establishing product sales, marketing, distribution and manufacturing capabilities; the amount and timing of future revenue, if any, received from commercial sales of our current and future product candidates upon any marketing approvals; and the costs of operating as a public company.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of securities offerings, debt financings, collaborations, strategic alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, existing ownership interest in our company may be materially diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the price of our securities. Additionally, we are subject to a number of affirmative and restrictive covenants pursuant to the OrbiMed Credit Agreement, which limit or restrict our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

If we raise funds through additional collaborations, strategic alliances or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional capital when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

We may require additional capital in order to continue to fund our operations through one or a combination of securities offerings, debt financings, collaborations, strategic alliances and/or licensing arrangements which may not be

available on a timely basis, on favorable terms, or at all, and such capital, if obtained, may not be sufficient to enable us to continue to implement our long-term business strategy. See factors further described in the sections titled "Risk Factors" in this Quarterly Report.

Our continuation as a going concern is dependent on our ability to generate sufficient cash flows from operations and/or obtain additional capital through one or a combination of securities offerings, debt financings, collaborations, strategic alliances and/or licensing arrangements to carry out our long-term business strategy. If we are unable to continue as a going concern, we may have to liquidate our assets and may receive less than fair value for such assets and less than the value at which such assets are carried on our financial statements, and it is likely that investors will lose all or a part of their investment. As discussed in Note (1) Nature of Business to our unaudited condensed consolidated financial statements accompanying this Quarterly Report, there is substantial doubt regarding our ability to continue as a going concern as of June 30, 2025.

Contractual Obligations and Commitments

Our contractual obligations as of June 30, 2025, include lease obligations of $2.1 million, reflecting the minimum commitments for our principal administrative and production facility and other office spaces.

Pursuant to the Asset Purchase Agreement, dated July 31, 2020, between TriSalus and Dynavax, we have paid Dynavax $12.0 million as of June 30, 2025, and may be required to pay Dynavax up to an additional $158 million upon the achievement of certain development and regulatory milestones with respect to nelitolimod. Subject to obtaining marketing approval for nelitolimod, we will also be required to pay up to $80 million upon achieving certain commercial milestones. The Dynavax Agreement also obligates us to pay low double-digit royalties based on potential future net sales of product containing nelitolimod compound on a product-by-product and country-by-country basis during the applicable royalty term. Such royalties are subject to reduction by up to 50% in certain circumstances.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet financing arrangements or any relationships with unconsolidated entities or financial partnerships, including entities sometimes referred to as structured finance or special purpose entities, which were established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Critical Accounting Policies and Estimates

Our significant accounting policies are summarized in Note (2) Summary of Significant Accounting Policies in the unaudited condensed consolidated financial statements accompanying this Quarterly Report. There have been no significant changes in our critical accounting policies during the six months ended June 30, 2025, as compared to the critical accounting policies disclosed in Management's Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on April 15, 2025. While all of these significant accounting policies affect the reporting of our financial condition and results of operations, we view certain of these policies as critical. Policies determined to be critical are those policies that have the most significant impact on our financial statements and require us to use a greater degree of judgment and/or estimates. Actual results may differ from those estimates. Additionally, changes in accounting estimates could occur in the future from period to period.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are a smaller reporting company as defined under Item 10(f)(1) of Regulation S-K of the Securities Act; we are not required to provide the information contemplated by this item.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in the Securities Exchange Act of 1934, as amended (the "Exchange Act") Rule 13a-15) that are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file or submit under the Exchange Act, is recorded, processed, summarized and reported within the time periods specified in the rules and forms promulgated by the Securities and Exchange Commission, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Because of the inherent limitations to the effectiveness of any system of disclosure controls and procedures, no evaluation of disclosure controls and procedures can provide absolute assurance that all control issues and instances of fraud, if any, with a company have been prevented or detected on a timely basis. Even disclosure controls and procedures determined to be effective can only provide reasonable assurance that their objectives are achieved.

Table of Contents

As of June 30, 2025, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) pursuant to Rule 13a-15 of the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are not effective at the reasonable assurance level.

Material Weaknesses

Our management has identified material weaknesses in our internal control over financial reporting and we may identify additional material weaknesses in the future. If we fail to remediate the material weaknesses or if we otherwise fail to establish and maintain effective control over financial reporting, it may adversely affect our ability to accurately and timely report our financial results, and may adversely affect investor confidence and business operations.

A material weakness is a deficiency or combination of deficiencies in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our condensed consolidated financial statements would not be prevented or detected on a timely basis. In connection with our audited consolidated financial statements for the years ended December 31, 2023, and December 31, 2024, and our unaudited condensed consolidated financial statements for the three months ended June 30, 2024, management identified material weaknesses in our internal control over financial reporting with respect to:

(i)a lack of sufficient number of trained resources with the appropriate skills and knowledge and with assigned responsibilities and accountability for the design and operation of internal controls over:

1.financial reporting,

2.patent costs,

3.certain R&D accruals,

4.certain general accruals,

5.accounting for leases under ASC 842,

6.accounting for revenue, and

7.accounting for significant transactions, including costs associated with the SEPA, the Exchange Warrants, and accounting for the OrbiMed Credit Agreement, including the Initial OrbiMed Commitment amount and the related derivative financial instruments;

(ii)inadequate controls over the accounting and financial reporting for the Business Combination;

(iii)inadequate internal controls over the valuation of the warrant and tranche rights and obligations and liabilities resulting from the series B-2 preferred stock financing, and the revenue base redemption liability associated with the Initial OrbiMed Commitment Amount;

(iv)inadequate design and implementation of controls over the conversion of data from our legacy stock-based compensation management system to our new system, over the assumptions used to calculate fair value of certain equity awards to support the recognition of stock compensation expense, and over the assumptions used to determine the achievement of the performance obligations of certain equity awards; and

(v)inadequate security management internal controls over certain IT applications supporting financial reporting, related to segregation of privileged IT user rights and to monitor elevated user activity.

Our management developed a remediation plan, and we have continued to take steps to remediate each of the material weaknesses described above. The remediation plan included hiring additional trained resources with requisite experience with complicated accounting issues, designing and enforcing processes that ensure adequate segregation of duties within the finance function and adequately reviewing the assumptions and inputs to accounting estimates and engaging outside expert consultants as needed. As of June 30, 2025, we are in the process of hiring additional trained resources with such requisite experience or selected outside expert consultants. We will continue to evaluate the existing finance function experience and expertise to identify additional resource and application needs to aid in the remediation of the material weaknesses. The material weaknesses will be considered remediated when our management designs and implements effective controls that operate for a sufficient period of time and management has concluded, through testing, that these controls are effective. Our management will continue to monitor the effectiveness of the remediation plan and will make the changes it determines to be appropriate.

Changes in Internal Control over Financial Reporting

Other than the material weaknesses and remediation efforts described above, there have been no changes in our internal control procedures over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the three months ended June 30, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Part II - Other Information

Item 1. Legal Proceedings

From time to time, we may be subject to litigation and claims arising in the ordinary course of business. We are not currently a party to any material legal proceedings and we are not aware of any pending or threatened legal proceedings against us that we believe could have a material adverse effect on our business, operating results, cash flows, or financial position.

Item 1A. Risk Factors

There have been no material changes in our risk factors. The Risk Factors identified in Item 1A. Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2024 continue to represent the most significant risks to the Company’s future results of operations and financial conditions.
