NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1: Basis of Presentation

Boardwalk Pipeline Partners, LP (the Company) is a Delaware limited partnership formed in 2005 to own and operate the business conducted by its primary subsidiary Boardwalk Pipelines, LP (Boardwalk Pipelines) and its operating subsidiaries, which consists of integrated pipeline and storage systems for natural gas and natural gas liquids and other hydrocarbons (herein referred to together as NGLs). As of ~~June~~September 30, 2024, Boardwalk Pipelines Holding Corp. (BPHC), a wholly owned subsidiary of Loews Corporation (Loews), owned directly or indirectly, 100% of the Company's capital.

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S.) (GAAP) have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting of only normal recurring accruals) necessary to present fairly the Company's financial position as of ~~June~~September 30, 2024, and December 31, 2023, its results of operations, comprehensive income and changes in partners' capital for the three and ~~six~~nine months ended ~~June~~September 30, 2024 and 2023, and its changes in cash flows for the ~~six~~nine months ended ~~June~~September 30, 2024 and 2023, in each case in accordance with GAAP. Reference is made to the Notes to the Consolidated Financial Statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2023 (2023 Annual Report on Form 10-K), which should be read in conjunction with these unaudited condensed consolidated financial statements. The accounting policies described in Note 2 of Part II, Item 8. of the Company's 2023 Annual Report on Form 10-K are the same policies that were used in preparing the accompanying unaudited condensed consolidated financial statements. Results of operations for interim periods may not necessarily be indicative of results for the full year.

Certain amounts reported in Other revenues were reclassified to Product sales to conform to the current presentation in connection with the acquisition discussed in Note 2. The amounts reclassified represent NGL product sales that occurred during 2023. Costs associated with these product sales were immaterial. The effect of the reclassification was a decrease in Other revenues and an increase in Product sales of $0.8 million for 2023. This reclassification had no impact on Total operating revenues, Operating income or Net income.

Short-Term Investment Accounting Policy

The Company has invested in short-term investments that have been classified as held-to-maturity as the Company has the intent and the ability to hold the short-term investments until they mature. As of ~~June~~September 30, 2024, the Company had recorded $~~509~~603.71 million of U.S. treasury bills on its Condensed Consolidated Balance Sheets, maturing in ~~September~~December 2024, at amortized cost. The carrying amount of the U.S. treasury bills iswas adjusted for the accretion of discounts over the remaining life of the investment. Income related to the U.S. treasury bills was recorded in Interest Income on the Condensed Consolidated Statements of Income. As of September 30, 2024, the U.S. treasury bills had unrecognized gains of $0.6 million.

Note 2: Acquisition

On September 29, 2023, Boardwalk Resources Company, LLC, a wholly owned subsidiary of the Company, acquired Williams Olefins Pipeline Holdco LLC, renamed Boardwalk Ethane Pipeline Holdco, LLC (Bayou Ethane) after the acquisition, from Williams Field Services Group, LLC for $355.0 million in cash.

Pro Forma Financial Information

The following unaudited pro forma results of operations of the Company are presented as if the acquisition occurred on January 1, 2023. Such results are not necessarily indicative of future results. These pro forma results also do not reflect any cost savings, operating synergies or revenue enhancements that the Company may achieve or the costs necessary to achieve those objectives (in millions):

•Depreciation and amortization expense was calculated using property, plant and equipment (PPE) and intangible asset amounts as determined by the purchase price allocation and estimated useful lives.

The amounts presented primarily consist of fixed fees or MVCs which are typically recognized over time as the performance obligation is satisfied, in accordance with firm service contracts, or at a point in time as guaranteed minimum fees associated with the performance obligation are satisfied under certain ethane supply contracts. For the Company's customers that are charged maximum tariff rates related to its Federal Energy Regulatory Commission (FERC) regulated operating subsidiaries, the amounts below reflect the current tariff rate for such services for the term of the agreements; however, the tariff rates may be subject to future adjustment. The Company has elected to exclude the following from the table: (a) unsatisfied performance obligations from usage fees associated with its firm services because of the variable nature of such services; (b) unsatisfied performance obligations from the ethane commodity indexed portion of ethane supply contracts because of the variable nature of ethane prices, and (c) consideration in contracts that is recognized in revenue as invoiced, such as for interruptible services. The estimated revenues reflected in the table may include estimated revenues that are anticipated under executed precedent transportation agreements for projects that are subject to regulatory approvals.

(2)In March 2024, the Company executed a 108-year firm storage agreement with a customer. The estimated annual revenue from this contract is $3.1 million, with $331.6 million of unsatisfied performance obligations included in the “Thereafter” column. Per the tariff provisions, this customer was required to provide 90 days of collateral and the Company can suspend services due to non-payment.

Note 4: Gas and Liquids Stored Underground and Gas and NGLs Receivables and Payables

The operating subsidiaries of the Company provide storage services whereby they store natural gas or NGLs on behalf of customers and also periodically hold customer gas under parking and lending (PAL) services. Since the customers retain title to the gas or NGLs held by the Company in providing these services, the Company does not record the related gas or NGLs on its Condensed Consolidated Balance Sheets.

The operating subsidiaries of the Company also periodically lend gas to customers under PAL and certain firm services, and lend ethylene to customers under exchange agreements, and gas or NGLs may be owed to the Company's operating subsidiaries as a result of transportation imbalances. As of ~~June~~September 30, 2024, the amount of gas owed to the Company's operating subsidiaries due to gas imbalances and gas loaned under PAL and certain firm service agreements was approximately 106.7 trillion British thermal units (TBtu). Assuming an average market price during ~~June~~September 2024 of $2.3317 per million British thermal unit (MMBtu), the market value of that gas was approximately $2414.95 million. As of ~~June~~September 30, 2024, the amount of ~~NGLs~~ethylene owed to the Company'’s operating subsidiaries ~~due~~from toethylene ~~imbalances~~loaned ~~was~~under ~~less~~exchange ~~than~~agreements 0was approximately 34.10 million ~~barrels,~~pounds. ~~which~~Assuming ~~had~~an aaverage market ~~value~~price ofduring ~~approximately~~September 2024 of $0.321 ~~million.~~per ~~As of June 30~~pound, ~~2024,~~the ~~and~~market ~~December 31,~~value ~~2023, there were no amounts~~ of that ethylene ~~owed~~was toapproximately ~~the~~$7.1 ~~Company’s operating subsidiaries under exchange agreements~~million.

Assuming an average market price during December 2023 of $2.33 per MMBtu, the market value of that gas was approximately $26.1 million. There were no amounts of ethylene owed to the Company's operating subsidiaries under exchange agreements as of December 31, 2023. As of September 30, 2024, and December 31, 2023, there were no outstanding NGL imbalances owed to the Company's operating subsidiaries.

Note 5: Fair Value Measurements and Investments

Financial Assets and Liabilities

The methods and assumptions used in estimating the fair value amounts included in the disclosures for financial assets and liabilities are consistent with those disclosed in the Company's 2023 Annual Report on Form 10-K.

The Company had equity securities recorded at fair value on a recurring basis in Other Current Assets of $2.5 million and $2.3 million as of ~~June~~September 30, 2024, and December 31, 2023, which were considered Level 1 investments. The Company had no liabilities recorded at fair value on a recurring basis as of ~~June~~September 30, 2024, and December 31, 2023.

The carrying amounts and estimated fair values of the Company's financial assets and liabilities which were not recorded at fair value on the Condensed Consolidated Balance Sheets as of ~~June~~September 30, 2024, and December 31, 2023, were as follows (in millions):

As of June 30, 2024				Estimated Fair Value

Note 6: Commitments and Contingencies

Legal Proceedings and Settlements

The Company and its subsidiaries are parties to various legal actions arising in the normal course of business. Management believes the disposition of these outstanding legal actions, including the legal actions identified below, will not have a material impact on the Company's financial condition, results of operations or cash flows.

Mishal and Berger Litigation

On May 25, 2018, plaintiffs Tsemach Mishal and Paul Berger (on behalf of themselves and the purported class, Plaintiffs) initiated a purported class action in the Court of Chancery of the State of Delaware (the Trial Court) against the following defendants: the Company, Boardwalk GP, LP (Boardwalk GP), Boardwalk GP, LLC and BPHC (together, Defendants), regarding the potential exercise by Boardwalk GP of its right to purchase the issued and outstanding common units of the Company not already owned by Boardwalk GP or its affiliates (Purchase Right).

On June 25, 2018, Plaintiffs and Defendants entered into a Stipulation and Agreement of Compromise and Settlement, subject to the approval of the Trial Court (the Proposed Settlement). Under the terms of the Proposed Settlement, the lawsuit would be dismissed, and related claims against the Defendants would be released by the Plaintiffs, if BPHC, the sole member of the general partner of Boardwalk GP, elected to cause Boardwalk GP to exercise its Purchase Right for a cash purchase price, as determined by the Company's Third Amended and Restated Agreement of Limited Partnership, as amended (the Limited Partnership Agreement), and gave notice of such election as provided in the Limited Partnership Agreement within a period specified by the Proposed Settlement. On June 29, 2018, Boardwalk GP elected to exercise the Purchase Right and gave notice within the period specified by the Proposed Settlement. On July 18, 2018, Boardwalk GP completed the purchase of the Company's common units pursuant to the Purchase Right.

On September 28, 2018, the Trial Court denied approval of the Proposed Settlement. On February 11, 2019, a substitute verified class action complaint was filed in this proceeding, which, among other things, added Loews as a Defendant. The Defendants filed a motion to dismiss, which was heard by the Trial Court in July 2019. In October 2019, the Trial Court

ruled on the motion and granted a partial dismissal, with certain aspects of the case proceeding to trial. A trial was held the week of February 22, 2021, and post-trial oral arguments were held on July 14, 2021.

On November 12, 2021, the Trial Court issued a ruling in the case. The Trial Court held that Boardwalk GP breached the Limited Partnership Agreement and found that Boardwalk GP iswas liable to the Plaintiffs for approximately $690.0 million in damages, plus pre-judgment interest (approximately $166.0 million), post-judgment interest and attorneys' fees. The Trial Court's ruling and damages award was against Boardwalk GP, and not the Company or its subsidiaries.

The Defendants believed that the Trial Court ruling included factual and legal errors. Therefore, on January 3, 2022, the Defendants appealed the Trial Court's ruling to the Supreme Court of the State of Delaware (the Supreme Court). On January 17, 2022, the Plaintiffs filed a cross-appeal to the Supreme Court contesting the calculation of damages by the Trial Court. Oral arguments were held on September 14, 2022, and on December 19, 2022, the Supreme Court reversed the Trial Court's ruling and remanded the case to the Trial Court for further proceedings related to claims not decided by the Trial Court's ruling. Briefing by the parties at the Trial Court on the remanded issues was completed in September 2023. A hearing on the remanded issues was held at the Trial Court in April 2024. In September 2024, the Trial Court ruled in favor of the Defendants on all of the remanded issues. On October 21, 2024, the Plaintiffs appealed the Trial Court's ruling on the remanded issues to the Supreme Court.

City of New Orleans Litigation

Gulf South Pipeline Company, LLC (Gulf South), along with several other energy companies operating in Southern Louisiana, has been named as a defendant in a petition for damages and injunctive relief in state district court for Orleans Parish, Louisiana, (Case No. 19-3466) by the City of New Orleans. The case was filed on March 29, 2019. The lawsuit claims include, among other things, negligence, strict liability, nuisance and breach of contract, alleging that the defendants' drilling, dredging, pipeline and industrial operations since the 1930s have caused increased storm surge risk, increased flood protection costs and unspecified damages to the City of New Orleans. In October 2020, this case was stayed pending the outcome of a consolidated appeal to the Fifth Circuit Court of Appeals in a similar case. On August 5, 2021, the Fifth Circuit Court of Appeals ruled in favor of the oil-and-gas defendants in that consolidated appeal, finding that the two cases being appealed should be re-examined in federal district court since they involve operations that were federally overseen at the time. The ruling reverses a previous decision that allowed the cases to be heard in state court, which the plaintiffs had sought. As a result of the Fifth Circuit Court of Appeals' decision, it is anticipated that this case will be reviewed in federal district court to determine whether the case should be heard in that court. Discovery has been initiated.

Gulf South and Texas Gas Transmission, LLC (Texas Gas) have been named as defendants in several suits in the State of Louisiana that are similar in nature to the City of New Orleans Litigation discussed above. These cases were filed in Louisiana state courts and discovery is ongoing. One of these cases was settled in the second quarter 2024 and it did not have a material impact to the Company's results of operations or equity.

Regulatory Cost Recovery Mechanism

On May 1, 2024, Gulf South filed with the FERC a regulatory cost recovery mechanism, to be included in Gulf South's tariff, that would allow Gulf South to track and recover, via a surcharge, the costs of complying with certain new environmental regulatory requirements and regulatory requirements imposed by the Pipeline and Hazardous Materials Safety Administration. Gulf South requested that the regulatory cost recovery mechanism have an initial term of five years beginning on November 1, 2024. ~~The~~On ~~mechanism~~October ~~remains~~31, ~~subject~~2024, toGulf South received an order from the FERC ~~approval.~~rejecting the cost recovery mechanism.

Commitments for Construction

The Company's future capital commitments are comprised of binding commitments under purchase orders for materials ordered but not received and firm commitments under binding construction service agreements. As of ~~June~~September 30, 2024, the commitments were approximately $~~170~~141.13 million, all of which are expected to be settled within the next twelve months.

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

The following discussion and analysis of financial condition and results of operations should be read in conjunction with our accompanying interim condensed consolidated financial statements and related notes, included elsewhere in this report, and prepared in accordance with accounting principles generally accepted in the United States of America (GAAP), and our consolidated financial statements, related notes, Management's Discussion and Analysis of Financial Condition and Results of Operations and Risk Factors included in our Annual Report on Form 10-K for the year ended December 31, 2023 (2023 Annual Report on Form 10-K).

We primarily operate in the midstream portion of the natural gas and natural gas liquids and other hydrocarbons industry, providing transportation and storage for those commodities. We also provide ethane supply services for industrial customers in Louisiana and Texas.

Results of Operations

Note 2 in Part II, Item 8. of our 2023 Annual Report on Form 10-K contains a summary of our revenue contracts and the related revenue recognition policies. A significant portion of our revenues are fee-based, being derived from capacity reservation charges under firm agreements with customers, which do not vary significantly period to period, but are impacted by longer-term trends in our business such as changes in pricing on contract renewals and other factors. We have little to no direct commodity price exposure. Our operating costs and expenses do not vary significantly based upon the amount of products transported, with the exception of costs recorded in Costs associated with service revenues on our Condensed Consolidated Statements of Income. Our operations and maintenance expenses are impacted by our compliance with the requirements of, among other regulations, the Pipeline and Hazardous Materials Safety Administration Mega Rule and our efforts to monitor, control and reduce emissions, as further discussed in our 2023 Annual Report on Form 10-K.

We use earnings before interest, income taxes, depreciation and amortization (EBITDA), a non-GAAP measure, as a financial measure to assess our operating and financial performance and return on invested capital. We believe that some investors may find this measure useful in evaluating our performance.

The following table presents a reconciliation of net income to EBITDA (in millions):

	For theSix Months EndedJune 30,
	For theNine Months EndedSeptember 30,
	2024		2023
Net income	$	~~262~~368.28	$	~~197~~266.79

Interest income	(1222.52)		(611.07)
EBITDA	$	~~552~~802.51	$	~~471~~675.24

For the ~~Six~~Nine Months Ended ~~June~~September 30, 2024 and 2023

Our net income for the ~~six~~nine months ended ~~June~~September 30, 2024, increased $64101.59 million, or 3338%, to $~~262~~368.28 million compared to $~~197~~266.79 million for the ~~six~~nine months ended ~~June~~September 30, 2023. Our EBITDA for the ~~six~~nine months ended ~~June~~September 30, 2024, increased $81126.37 million, or 1719%, to $~~552~~802.51 million as compared to the comparable 2023 period. Our net income and EBITDA increased primarily due to the factors discussed below, and also included increases of $711.45 million and $1219.76 million from the acquisition of Williams Olefins Pipeline Holdco, LLC (Bayou Ethane) in September 2023.

Operating revenues for the ~~six~~nine months ended ~~June~~September 30, 2024, increased $~~235~~352.08 million, or 3132%, to $~~988~~1,461.05 million compared to $~~753~~1,108.07 million for the ~~six~~nine months ended ~~June~~September 30, 2023. During the fourth quarter 2023, a customer released its no-notice service (NNS) into separate transportation and storage services, which resulted in an increase of storage revenues and a reduction in transportation revenues of $1219.71 million for the ~~six~~nine months ended ~~June~~September 30, 2024, compared to the comparable period in 2023. Excluding the $1219.71 million impact from the NNS contract, our transportation revenues increased $3961.62 million, primarily due to re-contracting at higher rates and recently completed growth projects; our storage, parking and lending revenues increased $1422.57 million due to favorable market conditions; our product sale revenues ~~from the sale of natural gas,~~

from the sale of natural gas, ethylene and propane increased by $1222.68 million; and the Bayou Ethane acquisition contributed $~~169~~245.2 4 million of operating revenues, primarily resulting from ethane product sales.

Operating costs and expenses for the ~~six~~nine months ended ~~June~~September 30, 2024, increased $~~167~~242.36 million, or 3533%, to $~~651~~981.4 million compared to $~~484~~738.18 million for the ~~six~~nine months ended ~~June~~September 30, 2023. Our operating expenses were primarily impacted by the Bayou Ethane acquisition, which added an additional $~~161~~233.8 9 million of operating costs, including $~~142~~205.74 million of costs associated with product sales and $58.3 1 million of depreciation and amortization expense.

Our depreciation and amortization expense and interest income and expense were impacted by the following items:

•higher depreciation and amortization expense of $1114.08 million from an increased asset base from recently completed growth projects and the Bayou Ethane acquisition; and

•higher interest expense of $1220.23 million due to pre-financing the $600.0 million debt maturing in December 2024 and higher interest income of $610.5 million due to income earned from cash invested in short-term investments.

Liquidity and Capital Resources

In February 2024, we issued $600.0 million aggregate principal amount of Boardwalk Pipelines, LP (Boardwalk Pipelines) 5.625% notes due August 2034. In the first ~~six~~nine months of 2024, we paid a total of $~~100~~150.0 million of distributions to Boardwalk GP, LP and Boardwalk Pipelines Holding Corp. We anticipate that our existing capital resources, including our cash and cash equivalents, short-term investments, revolving credit facility and our cash flows from operating activities, will be adequate to fund our operations and capital expenditures for 2024 and to retire our $600.0 million of debt that is maturing in December 2024. As of ~~June~~September 30, 2024, we also have an effective shelf registration statement on file with the Securities and Exchange Commission (SEC) under which we may publicly issue up to $900.0 million of debt securities, warrants or rights from time to time.

Guarantee of Securities of Subsidiaries

Our debt is primarily issued at Boardwalk Pipelines, our wholly owned subsidiary, although we have historically also issued debt at our operating subsidiaries. As of ~~June~~September 30, 2024, all of the outstanding notes issued by Boardwalk Pipelines (Subsidiary Issuer) and the full amount of the revolving credit facility, were guaranteed by us (Parent Guarantor). The purpose of the guarantees is to help simplify our reporting and capital structure.

We guarantee amounts borrowed under the revolving credit facility, but any amounts borrowed are not subject to the reporting requirements of Rule 13-01 of Regulation S-X (Rule 13-01). As of ~~June~~September 30, 2024, there were no outstanding borrowings under the revolving credit facility. The following table identifies our principal amounts outstanding for the debt that is subject to the disclosure rules of Rule 13-01 (in millions):

	As of June 30, 2024
	As of September 30, 2024
Principal amounts guaranteed by Boardwalk Pipeline Partners and subject to Rule 13-01 (1)	$	3,750.0
Principal amounts not guaranteed (2)	100.0
Other (3)	(1716.6)
Total debt and finance lease obligation	$	3,~~832~~833.4

(1)This represents principal amounts of all outstanding debt at Boardwalk Pipelines subject to the disclosure rules of Rule 13-01 (the Guaranteed Notes), including $600.0 million of outstanding principal amounts that has been classified as current.

(2)This represents principal amounts of outstanding debt at Texas Gas Transmission, LLC.

(3)This represents amounts related to a finance lease and unamortized debt discount and issuance costs.

The Guaranteed Notes are fully and unconditionally guaranteed by the Parent Guarantor on a senior unsecured basis. The guarantees of the Guaranteed Notes rank equally with all of our existing and future senior debt, including our guarantee of indebtedness under our revolving credit facility. The guarantees will be effectively subordinated in right of payment to all of

our future secured debt to the extent of the value of the assets securing such debt. There are no restrictions on the Subsidiary Issuer's ability to pay dividends or make loans to the Parent Guarantor. The guaranteed obligations will be terminated with respect to any series of notes if that series has been discharged or defeased.

Our operating assets, operating liabilities, operating revenues, expenses and other comprehensive income either exist at or are generated by our operating subsidiaries. The Parent Guarantor and the Subsidiary Issuer have no material assets, liabilities or operations independent of their respective financing activities, including the Guaranteed Notes and advances to and from each other, and their investments in the operating subsidiaries. For these reasons, we meet the criteria in Rule 13-01 to omit the summarized financial information from our disclosures.

Critical Accounting Estimates and Policies

Certain amounts included in or affecting our unaudited condensed consolidated financial statements and related disclosures must be estimated, requiring us to make certain judgments and assumptions with respect to values or conditions that cannot be known with certainty at the time the financial statements are prepared. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities in our condensed consolidated financial statements. We review our estimates and assumptions on an ongoing basis, utilizing historical experience, consultation with third parties and other methods we consider reasonable. Nevertheless, actual results may differ materially from our estimates. Any effects on our business, financial position or results of operations resulting from revisions to these estimates are recorded in the periods in which the facts that give rise to the revisions become known.

During 2024, there have been no significant changes to our critical accounting policies, judgments or estimates disclosed in our 2023 Annual Report on Form 10-K.

Forward-Looking Statements

Certain statements contained in this Quarterly Report on Form 10-Q, as well as some statements in our other filings with the SEC and periodic press releases and some statements made by our officials and our subsidiaries during presentations about us, are "forward-looking." Forward-looking statements include, without limitation, any statement that may project, indicate or imply future results, events, performance, intentions or achievements, and may contain the words "expect," "intend," "plan," "anticipate," "estimate," "believe," "will likely result" and similar expressions. In addition, any statement concerning future financial performance (including future revenues, earnings or growth rates), ongoing business strategies or prospects and possible actions by us or our subsidiaries, are also forward-looking statements.

Forward-looking statements are based on current expectations and projections about future events and their potential impact on us. While management believes that these forward-looking statements are reasonable as and when made, there is no assurance that future events affecting us will be those that we anticipate. All forward-looking statements are inherently subject to a variety of risks and uncertainties, many of which are beyond our control, which could cause actual results to differ materially from those anticipated or projected. These include, among others, the impacts of legislative and regulatory initiatives, or the implementation thereof, the impacts of climate change, environmental, social and governance matters and pipeline safety requirements and initiatives, the costs of maintaining and ensuring the integrity and reliability of our pipeline systems, our ability to complete growth projects that we have commenced or will commence, the risk of a failure in computer systems or cybersecurity attack, successful negotiation, consummation and completion of contemplated transactions, projects and agreements, risks and uncertainties related to the impacts of volatility in energy prices and our exposure to credit risk relating to default or bankruptcy by our customers. Developments in any of these areas could cause our results to differ materially from results that have been or may be anticipated or projected. Forward-looking statements speak only as of the date they are made and we expressly disclaim any obligation or undertaking to update these statements to reflect any change in our expectations or beliefs or any change in events, conditions or circumstances on which any forward-looking statement is based.

and we expressly disclaim any obligation or undertaking to update these statements to reflect any change in our expectations or beliefs or any change in events, conditions or circumstances on which any forward-looking statement is based.

Refer to Part I, Item 1A. of our 2023 Annual Report on Form 10-K for additional risks and uncertainties regarding our forward-looking statements.

Disclosure Controls and Procedures

As required by Rule 13a-15(b) of the Securities Exchange Act of 1934 (Exchange Act), we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q.

Based upon the evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of ~~June~~September 30, 2024, at the reasonable assurance level.
