NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

~~September~~December 3031, 2025

(Unaudited)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A) BASIS OF PRESENTATION

The condensed consolidated balance sheets as of ~~September~~December 3031, 2025 and June 30, 2025, the condensed consolidated statements of operations for the three and six months ended ~~September~~December 3031, 2025 and 2024, the condensed consolidated statements of cash flows for the ~~three~~six months ended ~~September~~December 3031, 2025 and 2024, and the condensed consolidated statements of stockholders' equity for the three and six months ended ~~September~~December 3031, 2025 and 2024, have been prepared by the Company in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and have not been audited. In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows for all periods presented have been made. The operating results for any interim period are not necessarily indicative of the operating results that may be experienced for the full fiscal year.

Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2025.

The preparation of financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses. Significant estimates and assumptions are used for, but are not limited to, allowances for credit losses, reserves for excess and obsolete inventories, long-lived and right-of-use assets, income tax valuation allowance, stock-based compensation and deferred compensation. Actual results could differ from the Company's estimates.

B) INVESTMENTS

Debt securities are classified as held-to-maturity as the Company has the positive intent and ability to hold them to maturity. The securities are carried at amortized cost as current or noncurrent based upon maturity date and unrealized gains and losses are recognized when realized. The amortized cost of debt securities is adjusted for amortization of premium and accretion of discounts to maturity. Such amortization or accretion is included in interest income, along with other interest income earned on cash and cash equivalents. Accrued interest receivable on held-to-maturity debt securities is shown separately on the condensed consolidated balance sheets and is not included in any estimate for credit losses. No allowance for credit losses on held-to-maturity U.S. Treasury securities is recorded as these securities have the following characteristics that support a zero-loss expectation: they are explicitly guaranteed by the U.S. government, are consistently highly rated by major rating agencies and have a long history of no credit losses. See Note 2 for additional information on investments.

C) FAIR VALUE MEASUREMENTS

Cash equivalents, accounts receivable, and accounts payable approximate fair value based on the short maturity of these instruments. The Company’s U.S. treasury debt securities are recorded at amortized cost with fair value disclosure. They have a readily available market price (Level 1 input), thus a lesser degree of judgment needs to be used in measuring fair value, and fair value was determined by quoted market prices. The fair value is based upon quoted market prices and is disclosed in Note 2.

An‎ income tax provision of $2,760 was recorded during the three months ended September 30, 2025 and 2024 for minimum state required tax payments only and there were no federal income tax provisions recorded due to net operating loss carryforwards (“NOLs”) available to offset taxable income. Application of available NOLs to potential future taxable income would minimize any tax payment requirements. NOLs arising in tax years beginning after December 31, 2017 are limited to 80 percent of taxable income

For~~ the ~~three~~time ~~months~~they ~~ended~~are ~~September 30, 2024, compensation expense of $197,374 was recorded under this arrangement~~recognized.

FState income tax provisions of $2,760 and $5,520, respectively, were recorded for the three- and six-month periods ending December 31, 2025 and 2024 for the required minimum state tax payments. There were no federal income tax provisions recorded during the first six months of fiscal years 2026 and 2025 due to net operating loss carryforwards (“NOLs”) ~~RECENT~~ ~~ACCOUNTING~~available ~~PRONOUNCEMENTS~~to offset taxable income. Application of available NOLs to potential future taxable income would minimize any tax payment requirements. NOLs arising in tax years beginning after December 31, 2017 are limited to 80 percent of taxable income per the Tax Cuts and Jobs Act (“TCJA”) and, as such, the future utilization of all federal NOLs available to the Company are so limited.

The Company's tax loss carryforward as of December 31, 2025 was approximately $34,760,000. Given the cumulative taxable losses for the last three years, excluding one-time items, the expectation for utilization of the estimated tax loss carryforward is not likely, and as such, the future realization of this continues to be uncertain. The valuation allowance was adjusted to continue to fully offset the net deferred tax asset as there is sufficient negative evidence to support a full valuation allowance.

G) DEFERRED COMPENSATION

The Company’s deferred compensation liability is for a current officer and is calculated based on years of service and compensation, along with various assumptions related to expected retirement date, discount rates, and mortality tables. The related expense is calculated using the net present value of the expected payments and is included in selling, general and administrative expenses in the condensed consolidated statements of operations. The deferred compensation liability recorded at December 31, 2025 and June 30, 2025 is $2,446,703 and $2,226,454, respectively. Compensation expense of $59,364 and $220,249, respectively, was recorded during the three and six months ended December 31, 2025 as a result of the increase in the deferred compensation liability for the current officer, due mainly to the annual increase in the future payments earned under the arrangement due to completing an additional year of service, as well as a decrease in the discount factor. The discount factor used to calculate the net present value of the liability was 5.81% at June 30, 2025 and declined to 5.45% at December 31, 2025. For the three and six months ended December 31, 2024, compensation (income) and expense of ($62,710) and $134,665, respectively, were recorded under this arrangement.

H) RECENT ACCOUNTING PRONOUNCEMENTS

Recently Adopted Accounting Pronouncements

In December 2023, FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The ASU focuses on income tax disclosures around effective tax rates and cash income taxes paid and requires consistent categories and greater disaggregation of information in the rate reconciliation, income taxes paid disaggregated by jurisdiction and certain other amendments. The new guidance was adopted prospectively as of July 1, 2025 and ASU 2023-09 does not mandate retrospective disclosure. Given the ASU relates solely to disclosure requirements, adoption does not have a material impact on the Company’s financial position, results of operations or cash flows. See Note 4 for further information.

Recently Issued Accounting Pronouncements Not Yet Adopted

In March 2024, FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220 40): Disaggregation of Certain Income Statement Expenses, which was subsequently amended by ASU 2025-01 in January 2025 to clarify and refine certain requirements. The ASU requires public business entities to disclose in the notes to the financial statements the amounts of employee compensation, depreciation, amortization, and inventory costs included in each relevant income statement line item. The guidance also requires disclosure of other expense categories if they are significant to an understanding of the entity’s financial performance. The amendments are effective for annual periods beginning after December 15, 2026, and for interim periods within fiscal years beginning after December 15, 2027 and entities are required to apply the amendments retrospectively. Early adoption is permitted.

The Company will evaluate the impact of the standards on its Consolidated Financial Statements and related disclosures. While the adoption of ASU 2024-03 and ASU 2025-01 will not affect the Company’s recognition, measurement or presentation of expenses on the face of the Consolidated Statements of Operations, it is expected to result in expanded disclosures in the notes to the Consolidated Financial Statements. The Company has not yet determined whether it will early adopt the guidance.

4. INCOME TAXES

The Company utilizes the liability method of accounting for income taxes. The liability method measures the expected income tax impact of future taxable income and deductions implicit in the condensed consolidated balance sheets. The Company’s income tax expense for the three and six months ended December 31, 2025 and 2024 consisted of the following:


	Three Months Ended				Six Months Ended
	December 31,				December 31,
		2025		2024		2025		2024

Foreign		—		—		—		—
Total income tax provision	$	2,760	$	2,760	$	5,520	$	5,520

All income is derived from domestic operations.

For the three and six months ended ~~September~~December 3031, 2025 ~~and 2024~~, respectively, the effective tax rate was less than 1.% and 1.7%, respectively. The effective tax rate for the three and 0six months ended December 31, 2024 was 2.8% and 1.7%, respectively. It is anticipated that the effective rate in future years will continue to be reduced by utilization of a portion or all of the available federal and state ~~net operating loss (~~NOL) carryforwards that existed as of June 30, 2025.

The effective tax rate for the current quarter differs from the U.S. federal statutory rate of 21% primarily due to:

State income taxes, net of federal benefit

Officer life insurance

Non-deductible meals and entertainment expense

Research and development tax credits

Nondeductible stock options expense

Changes in valuation allowances on deferred tax assets

‎The Company will provide the enhanced annual disclosures required by ASU 2023-09, including the detailed rate reconciliation and jurisdictional income taxes paid, in its Form 10-K for the year ending June 30, 2026.

No material changes in uncertain tax positions or valuation allowances were recorded during the three- and six-month ~~period~~periods ended ~~September~~December 3031, 2025 or 2024.

5. CREDIT FACILITY

On May 14, 2019, the Company entered into a secured credit facility (“Credit Agreement”) with Town Bank (“Lender”). The Credit Agreement provides for a $5,000,000 revolving secured credit facility for letters of credit for the benefit of the Company of up to a sublimit of $1,000,000. There are no unused line fees in the credit facility. On January 28, 2021, the Credit Agreement was amended to change the interest rate to Wall Street Journal Prime less 1.50%. An amendment to the Credit Agreement effective October 30, 2024, extended the maturity date to October 31, 2026, and removed one of the covenants requiring submission of annual financial performance projections to the Lender. The Company and the Lender also entered into a General Business Security Agreement dated May 14, 2019 under which the Company granted the Lender a security interest in substantially all of the Company’s assets in connection with the Company’s obligations under the Credit Agreement. The Credit Agreement contains certain affirmative and negative covenants customary for financings of this type. The negative covenants include restrictions on other indebtedness, liens, fundamental changes, certain investments, disposition of assets, mergers and liquidations, among other restrictions. As of ~~September~~December 3031, 2025, the Company was in compliance with all covenants related to the Credit Agreement. As of ~~September~~December 3031, 2025 and June 30, 2025, there were no outstanding borrowings on the facility.

~~6. REVENUE~~‎ ~~RECOGNITION~~

The Company disaggregates its net sales by geographical location as it believes it best depicts how the nature, timing and uncertainty of net sales and cash flows are affected by economic factors. The following table summarizes net sales by geographical location:

	Three Months Ended
	September 30,
	2025		2024
United States	$	3,321,738	$	2,167,364
Export		749,040		1,034,504
Net Sales	$	4,070,778	$	3,201,868

Deferred revenue relates primarily to consumer and customer warranties. These constitute future performance obligations, and the Company defers revenue related to these future performance obligations. Effective July 1, 2023, the Company increased its deferral rates from 2.4% to 3% for domestic sales and decreased its deferral rate from 10% to 8% for export sales to reflect recent warranty experience. In the three months ended September 30, 2025 and 2024, the Company recognized revenue, which was included in the deferred revenue liability at the beginning of those periods of $51,396 and $77,103, respectively, for performance obligations related to consumer and customer warranties. The Company estimates that the deferred revenue performance obligations are satisfied within one year to three years and therefore uses that same timeframe for recognition of the deferred revenue.

7. INCOME (LOSS) PER COMMON AND COMMON STOCK EQUIVALENT SHARE

Basic income (loss) per common share is computed based on the weighted-average number of common shares outstanding. Diluted income (loss) per common share is calculated assuming the exercise of stock options except where the result would be anti-dilutive. The following table reconciles the numerator and denominator used to calculate basic and diluted income (loss) per share:

8. RELATED PARTY TRANSACTIONS

The Company leases its facility in Milwaukee, Wisconsin from Koss Holdings, LLC, which is controlled by five equal ownership interests in trusts held by the five beneficiaries of a former chairman’s revocable trust and includes current stockholders of the Company. On May 24, 2022, the lease was renewed for a period of five years, ending June 30, 2028, and is being accounted for as an operating lease. The lease extension maintained the rent at a fixed rate of $380,000 per year and included an option to renew at an increased rate of $397,000 for an additional five years ending June 30, 2033. The negotiated increase in rent slated for 2028 will be the first increase in rent since 1996. The Company is responsible for all property maintenance, insurance, taxes and other normal expenses related to ownership.

9. ACCOUNTS RECEIVABLE CONCENTRATIONS

As of ~~September~~December 3031, 2025, ~~four~~three of the Company’s customers each represented more than 10% of total accounts receivable, and collectively these customers accounted for approximately 6146% of total accounts receivable (2319%, 1614% ~~11%~~ and 1113%, respectively). At June 30, 2025, three customers each represented more than 10% of total accounts receivable (16%, 13% and 11%, respectively), comprising approximately 40% of total trade receivables.

10. SEGMENT INFORMATION

The Company has a single reportable segment, the design, manufacture and sale of headphones and related accessories, which reflects the manner in which the Company’s Chief Executive Officer, who is the Company’s chief operating decision maker (“CODM”), regularly reviews financial information to manage the business, allocate resources and assess performance. The headphones are sold through retailers and distributors both domestically and internationally, as well as direct-to-consumer.

The CODM also reviews the following balance sheet items at period-end as part of performance monitoring and resource allocation decisions:

As of	~~September~~December 3031, 2025		June 30, 2025
Cash and cash equivalents	$	2,~~515~~464,~~913~~838	$	2,807,797

Total segment assets		3736,~~663~~769,~~395~~678		37,184,609

The Company applied the provisions of ASU 2023-07 retrospectively and has included comparative information for the three and six months ended ~~September~~December 3031, 2024 for statement of operations items. Because the Company operates as a single reportable segment, the amounts above reconcile directly to the corresponding condensed consolidated financial statement line items. There was no impact on previously reported consolidated net income, financial position or cash flows.

11. LEGAL MATTERS

As of ~~September~~December 3031, 2025, the Company is involved in the matters described below:

•The Company maintains a program focused on enforcing its intellectual property and, in particular, certain patents in its patent portfolio. As part of this program, the Company filed complaints against certain parties alleging infringement on the Company’s patents relating to its wireless audio technology. In the event that a monetary award or judgment is received by the Company in connection with these complaints, all or portions of such amounts, such as contingent legal fees, will be due to third parties. The Company may incur additional fees and costs related to these lawsuits, however, timing and impact on its condensed financial statements is uncertain. Depending on the response to and the underlying results of the enforcement program, the Company may continue to litigate its claims, enter into licensing arrangements or reach some other outcome potentially advantageous to its competitive position.

The ultimate resolution of these matters is not determinable unless otherwise noted.

In early fiscal 2020, the Company was notified by One-E-Way, Inc. (“One-E-Way”) that some of the Company's wireless products may infringe on certain One-E-Way patents. A Supplemental Notice of Infringement was served on the Company on March 18, 2025 and the complaint was settled in September 2025. The matter was settled for $22,200 and had been adequately accrued for as of June 30, 2025. 13

On November 20, 2025, the Company resolved its lawsuit against PEAG, LLC d/b/a JLab Audio and granted a license covering certain of its patents. Gross proceeds of $250,000 were recognized and recorded as other income during the three and six months ended December 31, 2025. Total contingent legal fees and related expenses of $250,000 offset these proceeds and were recorded as a selling, general and administrative expense during the three and six months ended December 31, 2025.

In early fiscal 2020, the Company was notified by One-E-Way, Inc. (“One-E-Way”) that some of the Company's wireless products may infringe on certain One-E-Way patents. A Supplemental Notice of Infringement was served on the Company on March 18, 2025 and the complaint was resolved in September 2025. The matter was resolved at a cost of $22,200 and had been adequately accrued for as of June 30, 2025.

The Company is also subject to a variety of other claims and suits that arise from time to time in the ordinary course of its business. Although management currently believes that resolving these claims against the Company, individually or in the aggregate, will not have a material adverse impact on its condensed consolidated financial statements, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future.

Fiscal 2026 Period Results Compared with Fiscal 2025 Period

(comments refer to the three and six-month periods ended ~~September~~December 3031, 2025 and 2024 unless otherwise noted)

Net sales for the three months ended ~~September~~December 3031, 2025 totaled $42,~~071~~861,000, ~~which~~a ~~reflects~~decrease ~~an increase~~ of $~~869~~696,000, or 2719.16%, compared to $3,~~202~~557,000 infor the ~~same~~three ~~period~~months ofended ~~the~~December ~~previous~~31, ~~year~~2024. ~~This~~The ~~growth~~decrease was ~~primarily~~almost ~~attributable~~entirely due to anew ~~substantial~~product ~~order~~sales ~~from~~to anthe ~~Education~~European ~~customer~~market in the second three months of the prior year, aswhich ~~well~~did asnot anrepeat at the same level in the current period. Gains in sales to certain of the Company’s domestic distributors and a slight increase in direct-to-consumer (DTC) sales slightly offset the declines. For the six months ended December 31, 2025, sales of $~~170~~6,932,000 were $173,000, or 222.56%, ~~and~~ahead aof ~~notable~~the ~~243%~~same ~~year-over-year~~period ~~rise~~ in ~~sales~~the toprior ~~the~~year ~~Asia~~as ~~market.~~a ~~These~~result ~~gains,~~of ~~however,~~a ~~were~~considerable ~~partially~~sale ~~offset~~of bycustom ~~delays~~headphones to a customer in ~~re-orders~~the ~~from~~Education ~~certain~~segment, ~~customers~~offset by deficits in ~~the~~sales to European ~~market~~distributors.

Significant new product sales in the prior year were the primary driver of lower current year sales. Strong sales to our Asian distributors, an increase of 115% compared to the prior year, helped to offset some of the decline.

Tariff policies have fluctuated over the last ~~six~~twelve months, particularly with respect to trade policies and tariffs applied to trade between China and the U.S. The Company is currently subject to certain tariff rates on products manufactured in China that are now lower than those previously imposed and should remain stable until November 2026, but future changes in trade policy could result in significantly higher duties. Federal courts have ruled that the broad tariffs imposed under the International Emergency Economic Powers Act (IEEPA) are illegal and exceeded the President’s statutory authority,. ~~however,~~The ~~the~~ Supreme Court isheard ~~scheduled~~oral arguments on November 5, 2025 to consider the IEEPA tariffs in the consolidated case of Learning Resources v. Trump, and other companies have joined in ~~November~~the ~~2025~~IEEPA tariff dispute. As of mid-January 2026, the U.S. Supreme Cout had not yet issued a decision. If the Supreme Court ultimately rules that the IEEPA tariffs were illegally imposed, ~~duty~~importers ~~refunds~~ could beseek ~~possible~~reliquidation and refunds, though the administration could turn to other statutes to support tariffs. Given the volatility of the tariff landscape and the substantial amount of product coming from China, the Company continues to closely monitor the latest updates and their impact on operations, planning efforts and financial conditions.

State tax expense of $2,760 was recorded for each of the three months ended September 30, 2025 and 2024, reflecting the minimum required state tax due. No federal income tax was recorded due to net operating loss (NOL) carryforwards available to offset most taxable income. The effective tax rate for the three months ended September 30, 2025 and 2024 was 1.1% and 0.7%, respectively. It is anticipated that the effective rate in future years will continue to be reduced by utilization of a portion or all of the available federal and state net operating loss (NOL) carryforwards that existed as of June 30, 2025.17

The Company’s remaining expected federal tax loss carryforward approximates $34,500,000 at the end of the first quarter of fiscal year 2026, resulting in a deferred tax asset related to the Company's net operating loss carry forwards of roughly $8,800,000 as of September 30, 2025. The valuation allowance was adjusted accordingly to fully offset the net deferred tax asset as there is not sufficient positive evidence to support a reduction in a full valuation allowance as, excluding unusual, infrequent items, a three-year cumulative tax loss has occurred.

and an increase in the annual payments under the plan given an additional year of service was completed, was mostly offset by a decline in other legal and professional fees unrelated to patent litigation.

Other income for the three and six months ended December 31, 2025 consisted entirely of $250,000 in non-recurring licensing proceeds. There was no other income recorded for the three and six months ended December 31, 2024.

State tax expense of $2,760 was recorded for each of the three months ended December 31, 2025 and 2024 and $5,520 was recorded for each of the six months ended December 31, 2025 and 2024, reflecting the minimum required state tax due. No federal income tax was recorded during the first half of fiscal year 2026 due to net operating loss (NOL) carryforwards available to offset most taxable income. The effective tax rate for the three and six months ended December 31, 2025 was less than 1% and 1.7%, respectively. The effective tax rate for the three and six months ended December 31, 2024 was 2.8% and 1.7%, respectively. It is anticipated that the effective rate in future years will continue to be reduced by utilization of a portion or all of the available federal and state NOL carryforwards that existed as of June 30, 2025.

The Company’s remaining expected federal tax loss carryforward approximates $34,760,000 at the end of the second quarter of fiscal year 2026, resulting in a deferred tax asset related to the Company's federal and state net operating loss carry forwards of roughly $8,877,000 as of December 31, 2025. The valuation allowance was adjusted accordingly to fully offset the net deferred tax asset as there is not sufficient positive evidence to support a reduction in a full valuation allowance as, excluding unusual, infrequent items, a three-year cumulative tax loss has occurred.

The Company maintains a program focused on enforcing its intellectual property and, in particular, certain of its patent portfolio. The Company has enforced its intellectual property by filing complaints against certain parties alleging infringement on the Company’s patents relating to its wireless headphone technology. If efforts are successful, the Company may receive royalties, offers to purchase its intellectual property, or other remedies advantageous to its competitive position from time to time. However, there is no guarantee of a positive outcome from these efforts in the future, which could ultimately be time-consuming and unsuccessful. Additionally, the Company may owe all or a portion of any future proceeds arising from the enforcement program to third parties.

The Company believes that its financial position remains strong. The Company had $2.5 million of cash and cash equivalents, $13.90 million of short-term investments and available credit facilities of $5.0 million on ~~September~~December 3031, 2025. The Company also had $4.0 million of long-term investments in U.S. treasury debt securities on ~~September~~December 3031, 2025.

Recent Trends

Recent and ongoing macroeconomic and geopolitical conditions have impacted, and will continue to impact, our business. These include economic uncertainty from ~~unexpected job growth,~~ tariff volatility and ~~the~~ global trade ~~war~~tensions, ~~elevated~~persistent inflation pressures, ~~weakening~~a ofsoftening ~~the~~ job market and rising long-term unemployment, ~~sustained~~still ~~higher~~elevated borrowing costs, even after three quarter-point interest ~~rates~~rate ~~(albeit~~cuts ~~descending~~in ~~over~~the first half of the ~~last~~Company’s ~~few~~fiscal ~~months)~~year, ~~reduced~~steadily declining consumer confidence, disruption in our supply chain, the conflict in Eastern Europe and instability in the Middle East and increased risk of cyberattacks.

While the impact of these factors on our fiscal 2026 performance remains uncertain, we will continue to evaluate the extent to which these factors will impact our business, financial condition, or results of operations. These and other uncertainties with respect to these recent events could result in changes to our current expectations.

Government Shutdown - The federal government shutdown on October 1, 2025, when new appropriations or a continuing resolution failed to be passed. ~~The~~A ~~economic~~continuing ~~impact~~resolution ofwas asigned ~~short~~on ~~shutdown~~November on12, 2025 to reopen the ~~economy~~government iswith an agreement to provide temporary funding for most agencies through January 30, 2026.

The Company does provide product to the federal government and fulfillment of these orders ~~has~~was ~~been~~ delayed as a direct result of the shutdown.

Tariffs - In April 2025, the U.S. government imposed tariffs of up to 145% in certain imports from China, which significantly increased the Company’s expected duty cost for goods sourced from China. Since then, President Trump and his administration have implemented several temporary pauses to allow for trade negotiations. In May 2025, a 90-day tariff truce between the U.S. and China reduced reciprocal tariffs down to 10%, however, an additional 20% fentanyl-related tariff remained, resulting in a total 30% tariff on many Chinese goods. In August 2025, President Trump signed an executive order extending the tariff pause for another 90 days, with the suspension of additional reciprocal tariffs on Chinese goods remaining in effect until November 10, 2025 while trade negotiations continue. AsOn ofNovember ~~October 30~~10, 2025, ~~it has been reported that~~ the fentanyl-related ~~tariff~~tariffs ~~has~~were ~~been~~ reduced by half, to 10%. ~~The~~following ~~suspension~~an ofExecutive ~~further,~~Order ~~heightened~~by ~~tariffs~~President ~~allows time to de-escalate tensions and reach a potential long-term agreement.

Inflationary Cost Environment and the Impact on Consumer Confidence – In addition to the expected inflation as a result of the newly imposed tariffs, sustained higher interest rates and higher energy costs continue. While the Federal Reserve cut its benchmark federal funds rate by .25 percentage points since June 30, 2025, the overall effect on consumer sentiment and purchasing decisions is muted because a small cut typically does not offset more dominant economic factors, such as concerns over inflation and the labor market. Consumers may still put off making purchase decisions and cut back on overall spending, which could impact the Company’s sales volumes. 18

As noted, the Company will experience higher costs for commodities and packaging materials due to the recently enacted tariffs and will react with pricing actions in the coming quarter and as it deems necessary. The Company continues to work with a dedicated freight forwarding partner to minimize freight rate increases. Other risk factors further exacerbated by inflation include supply chain disruptions, increased oil and energy costs, risks of international operations and the recruitment and retention of talent.

Supply Chain Disruption and Trade Tensions with China - The Company faces significant risks due to reliance on third-party supply chains, primarily in southern China and Taiwan, distribution networks and the availability of necessary components to produce a considerable number of our products. Issues such as pandemic restrictions, geopolitical unrest, labor shortages, strikes, and component procurement failures could delay manufacturing and increase costs. The escalating U.S.-China tariff war has severely disrupted supply chains, impacting both domestic industries and global trade dynamics. Continued geopolitical tensions between China and Taiwan may affect future shipments from Taiwan-based suppliers. Adverse changes in social, political, regulatory, or economic conditions could increase product costs or delay shipments. The escalation of trade tensions might lead to retaliatory trade restrictions, potentially affecting the Company's ability to source products from China or conduct business internationally. Any alterations to our business strategy or operations made in order to adapt to or comply with any such changes would be time-consuming and expensive, with limited ability to pass increased tariffs and freight costs onto customers. Broad tariffs may shift supply chains out of China, which could cause inflation to rise, impacting costs and consumer demand. The Company will continue to monitor the evolving situation and others that may arise as the changes in the current labor landscape, coupled with rising inflation and energy prices, could potentially exacerbate disruptions in the supply chain, delay product shipments and increase transportation costs.

Russia’s Invasion of Ukraine – The United States and global markets continue to experience volatility and disruption resulting from the ongoing conflict between Russia and Ukraine, which began following the invasion of Ukraine by Russia in February 2022. The significant sanctions and export controls imposed against Russia, certain Russian banks and Russian individuals by the U.S. and other countries remain unchanged. The Company suspended all sales to Russia in April 2022 in accordance with Executive Order 14071 and no sales were made to Russia since that time. While there is a humanitarian crisis in Ukraine created by the war and the population continues to seek refuge in other countries, the Company continues to receive orders from a Ukrainian distributor. During the three and six months ended December 31, 2024, there were nearly $39,000 in sales to this distributor. There were no sales to the Ukrainian distributor in the six months of fiscal year 2026, however, an order for approximately $30,000 was received and will ship out in the coming quarter.

Cyberattacks - Cyberattacks are a growing geopolitical risk, becoming larger, more frequent, more sophisticated and more relentless as technology has evolved, resulting in privacy, security, and compliance concerns. They are a significant threat to individual organizations and national security. High-profile security breaches at other companies and in government agencies have increased in recent years, and security industry experts and government officials have warned about the risks of hackers and cyberattacks targeting businesses. We rely on accounting, financial, and operational management information systems to conduct our operations. Any disruption in these systems could adversely affect our ability to conduct our business. Furthermore, as part of our normal business activities, we collect and store common confidential information about customers, employees, vendors, and suppliers. This information is entitled to protection under a number of regulatory regimes. Any failure to maintain the security of the data, including the penetration of our network security and the misappropriation of confidential and personal information, could result in business disruption, damage to our reputation, financial obligations to third parties, fines, penalties, regulatory proceedings and private litigation with potentially large costs, and also result in deterioration in customers confidence in us and other competitive disadvantages, and thus could have a material adverse impact on our financial condition and results of operations. While we devote resources to security measures to protect our systems and data, these measures cannot provide absolute security and there is a risk that these types of attacks could impact the entire supply and distribution chain for the Company’s product line. Given connectivity through the internet, the Company can only be as strong as its weakest link, whether that is a financial service provider, third party distributor, reseller, transportation service provider, contract manufacturer, customer or consumer.

There were no purchases of common stock in the ~~three~~six months ended ~~September~~December 3031, 2025 or 2024 under the Company’s stock repurchase program.

Liquidity

The Company believes its existing cash and cash equivalents, investments in short-term U.S. Treasury securities, cash provided by operating activities and available borrowings under its credit facility, if any, will be sufficient to meet its anticipated working capital, and capital expenditure requirements during the next twelve months. There can be no assurance, however, that the Company’s business will continue to generate cash flow at current levels. If the Company is unable to generate sufficient cash flow from operations, then it may be required to sell assets, reduce capital expenditures, or draw on its credit facilities. The Company regularly evaluates new product offerings, inventory levels and capital expenditures to ensure that it is effectively allocating resources in line with current market conditions.

Contractual Obligation

The Company leases its 126,000 square foot facility from Koss Holdings, LLC, which is controlled by five equal ownership interests in trusts held by the five beneficiaries of a former chairman’s revocable trust and includes current stockholders of the Company.

The lease extension maintained the rent at a fixed rate of $380,000 per year. The Company has the option to renew the lease for an additional five years beginning July 1, 2028 and ending June 30, 2033 under the same terms and conditions except that the annual rent will increase to $397,000.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e)) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) are designed to ensure that: (1) information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms; and (2) such information is accumulated and communicated to management, including the principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

The Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of ~~September~~December 3031, 2025. The Company’s Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures as of ~~September~~December 3031, 2025 were effective.

Changes in Internal Control Over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting (as defined in Exchange Act Rules 13a–15(f) and 15d–15(f)) that occurred during the Company’s most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
