About KOSS CORP

Source: Item 1 (Business) from the 10-K filed August 28, 2026. Description as filed by the company with the SEC.

ITEM 1. BUSINESS

GENERAL

As used herein unless the context otherwise requires, the term “Company” means Koss Corporation and its subsidiaries, Koss Corp B.V. and Koss U.K. Limited. Koss Corporation was incorporated in Delaware in 1971. It formed Koss Corp B.V. and Koss U.K. Limited to comply with certain European Union (“EU”) requirements. Koss U.K. Limited is maintained to comply with certain U.K. requirements.

The Company operates in the audio/video industry segment of the home entertainment and communication industry through its design, manufacture and sale of stereo headphones and related accessory products. The Company reports its results as a single reporting segment, as the Company’s only business line is the design, manufacture and sale of stereo headphones and related personal listening accessories.

The Company’s products are sold through U.S. distributors, international distributors, audio specialty stores, the internet, national retailers, grocery stores, electronics retailers, and prisons under the “Koss” name as well as private label. The Company also sells products to distributors for resale to school systems, and directly to other manufacturers for inclusion with their own products. International markets are served by domestic sales representatives and sales personnel in the Netherlands and the Caucasus region. The Company utilizes independent distributors in several foreign countries.

Approximately 80% of the Company’s fiscal year 2026 sales were from stereo headphones used for listening to music. The remaining approximately 20% of the Company’s sales were from headphones used in communications, education settings, and in conjunction with metal detectors, as well as sold to original equipment manufacturers (“OEM”). The products are not significantly differentiated by their retail sales channel or application with the exception of products sold to school systems, prisons, and OEM customers. There are no other product line differentiations other than the quality of the sound produced by the stereo headphone itself, which is highly subjective.

Read full description ↓

The Company sources complete stereo headphones manufactured to its specifications from various manufacturers in Asia as well as raw materials used to produce stereo headphones at its plant in Milwaukee, Wisconsin. Management believes that it has sources of complete stereo headphones and raw materials that are adequate for its needs.

There are no employment or compensation commitments between the Company and its dealers. The Company has contracted several independent manufacturers’ representatives as part of its distribution efforts. The arrangements with foreign distributors do not contemplate that the Company pays any compensation other than any profit the distributors make upon their sale of the Company’s products.

Diversification Strategy

During the fiscal year ended June 30, 2026, management announced its intention to pursue acquisition targets as part of its “diversification by acquisition” strategy. The success of the Company’s intellectual property enforcement campaign, coupled with prudential cash management, has created an attractive opportunity to begin a new phase outside of the consumer electronics space. This includes acquiring upstanding, strong cash flow companies that the Company can grow and hold as part of the Company for the long-term, and preferably forever.

The Company expects this expanded strategy to substantially change its financial profile over the next one to five years and generate predictable, recurring revenue streams. However, during the acquisition phase, selling, general and administrative costs are expected to increase in the near term. The Company believes its existing cash, cash equivalents, and operating cash flows will provide meaningful support for funding this strategic transition.

INTELLECTUAL PROPERTY

John C. Koss is recognized for creating the personal listening industry with the first Koss SP/3 stereo headphone in 1958. The Company regularly applies for registration of its trademarks in many countries around the world, and over the years the Company has had numerous trademarks registered and patents issued in North America, South America, Asia, Europe, Africa, and Australia. As of June 30, 2026, the Company had approximately 400 trademarks registered in approximately 88 countries around the world and nearly 170 patents in approximately 25 countries. The Company has trademarks to protect the brand name, Koss, and its logo on its products. The Company also holds many design patents that protect the unique visual appearance of some of its products. These trademarks and patents are important to differentiate the Company from its competitors. Certain of the Company’s trademarks are of material value

and importance to the conduct of its business. The Company considers protection of its proprietary developments important; however, the Company’s business is not, in the opinion of management, materially dependent upon any single trademark or patent.

Given the significance of the Company’s intellectual property to its business, in 2019 the Company launched a program to enforce its intellectual property rights and protect its patent portfolio. As part of this enforcement program, the Company has filed and pursued lawsuits against a number of companies that the Company believes have infringed or are infringing upon its patents and may enter into licensing agreements or initiate additional lawsuits. The Company considers protecting its intellectual property rights to be central to its business model and competitive position in the stereo headphone industry.

SEASONALITY

Although retail sales of consumer electronics have historically been higher during the holiday season, sales of stereo headphones are generally smooth throughout the year. Management believes that the Company’s business is not seasonal as evidenced by the fact that the Company’s net sales for the last three years, including the year ended June 30, 2026, were fairly evenly dispersed throughout the year, with the exception of the first quarter of fiscal 2026, which was abnormally higher given a large custom order that shipped in that quarter. Management believes that the reason for this level performance of sales to retailers and distributors is related to the fact that consumers are increasingly purchasing stereo headphones throughout the year as replacements for older or lower quality headphones to improve the quality of their listening experience as it relates to portable electronic products. Therefore, upgrades and replacements appear to have as much interest over the course of the year as gifts of stereo headphones during the holiday season.

WORKING CAPITAL

The Company’s working capital needs do not differ substantially from those of its competitors in the industry and generally reflect the need to carry sufficient amounts of inventory to meet the delivery requirements of its customers. On a limited basis, the Company does offer 90-120 day payment terms to certain customers and may, on a rare occasion, extend payment terms to its customers for a special promotion. Based on historical trends, management does not expect these practices to have a material effect on net sales or net income.

CUSTOMERS

The Company markets a line of products used by consumers to listen to music, to work and study from home, to communicate via telephone or internet, and to listen to other audio-related media. The Company distributes these products through distributors and retail channels in the U.S. and independent distributors throughout the rest of the world. Additionally, the Company fills direct-to-consumer (“DTC”) orders on its website and via online marketplaces. The Company markets its products through many domestic retail outlets and numerous retailers worldwide. The Company also markets products directly to several OEMs for use in their products. In the fiscal years ended June 30, 2026 and 2025, the Company’s largest sales concentration was represented by its own DTC offerings via the Amazon portal and were approximately 22% and 19% of net sales in fiscal years 2026 and 2025, respectively. The Company’s products have broad distribution worldwide across many channels including distributors, specialty stores, mass merchants, and electronics stores. The Company is dependent upon its ability to retain a base of retailers and distributors to sell the Company’s line of products. A material loss or disruption of retailers and/or distributors could result in a loss of product placement and have an adverse effect on the Company’s financial results. The Company’s five largest customers accounted for approximately 49% and 50% of net sales in fiscal years 2026 and 2025, respectively.

COMPETITION

The Company principally focuses on the stereo headphone industry. In the stereo headphone market, the Company competes with all major competitors, many of which are large and diversified and have greater total assets and resources than the Company. The extent to which retailers and consumers view the Company as a pioneer in the creation of the personal listening industry, an innovative vendor of high-quality stereo headphone products, and a provider of excellent after-sales customer service and direct sales, is the extent to which the Company offers a competitive advantage. The Company relies upon its unique sound, quality workmanship, brand identification, engineering skills, and customer service, as well as its intellectual property portfolio, to support its competitive position.

RESEARCH AND DEVELOPMENT

The Company’s research and development activities are conducted by both Company personnel and outside consultants. The Company expects to incur on-going research and development costs related to its Bluetooth® and traditional wired headphones as it is planning to introduce new product offerings on a regular basis. The increasing costs related to worldwide certification of these technologies by country has increased the costs of regional compliance testing and has impacted the time to market on these wireless items.

ENVIRONMENTAL MATTERS

The Company believes that it has materially complied with all currently existing federal, state and local statutes and regulations regarding environmental standards and occupational safety and health matters to which it is subject. During fiscal years 2026 and 2025, the amounts incurred in complying with federal, state and local statutes and regulations pertaining to environmental standards and occupational safety and health laws and regulations did not materially affect the Company’s operating results or financial condition. The increased public awareness and concern regarding climate change has resulted in increased regulations which are rapidly evolving. The Company continues to monitor the evolving regulations, as well as related required disclosures, to ensure that we will be conformant. It is unclear as to whether any emerging and evolving regulations will have a material impact on the Company's results of operations.

EMPLOYEES

As of June 30, 2026, the Company employed 30 employees, 2 of which were part-time employees. The Company did not engage any temporary personnel during the year ended June 30, 2026. None of our employees are covered by a collective bargaining agreement.

FOREIGN SALES

The Company markets and sells its products in North America, Europe, Asia-Pacific, Latin America and other international markets. International operations are subject to various risks, including changes in economic conditions, political and social instability, fluctuations in foreign currency exchange rates, changes in trade policies and tariffs, import and export restrictions, differing regulatory requirements, and changes in tax laws. While no individual foreign country represented a material portion of our consolidated revenue during fiscal 2026, international sales represented approximately 17% of consolidated net sales.

For further information, see Part II, Item 7, as well as additional description of risks related to our business in foreign markets described in Part I, Item 1A. under “We may be subject to risks related to doing business in, and having counterparties based in, foreign countries.”

The Company has sales personnel currently located in the Netherlands and the Caucasus region to service the international export marketplace. The loss of these personnel would result in a transfer of sales and marketing responsibility. The Company mainly sells its products to independent distributors in countries and regions outside the United States including Europe, the Middle East, Asia, Australia, South America, Latin America, Canada and Mexico. During the last two fiscal years, net sales of all Koss products were distributed as follows:

MANUFACTURING OPERATIONS

The Company has a manufacturing facility in Milwaukee, Wisconsin and uses third-party contract manufacturers, for which long-standing relationships have been maintained, to produce substantially all its products. The contract manufacturers are primarily located in the People’s Republic of China and Taiwan and are responsible for component procurement, product assembly, testing and packaging in accordance with the Company’s specifications and quality standards. Because substantially all manufacturing is concentrated in China, the Company’s operations are subject to risks associated with changes in tariffs and trade policies, export controls, geopolitical developments, international shipping availability and costs, foreign currency fluctuations, labor market conditions and regulatory requirements. We actively manage these risks through ongoing supplier oversight via a contract employee based in China, inventory planning, business continuity planning and evaluation of alternative sourcing and manufacturing opportunities where commercially appropriate. Although the Company has seen increased logistics costs and higher import duties associated with products manufactured in China, manufacturing capacity has remained adequate to support anticipated customer demand. The Company also maintains finished goods inventory in its U.S. facility to mitigate this risk. The Company’s goal is to stock finished goods inventory at an average of approximately 90 days demand per item. Recovery of a single facility through

replacement of a supplier in the event of a disaster or suspension of supply could take an estimated six to twelve months, in which case the Company believes that it could restore production of its top 10 selling models (which represented approximately 51% of the Company’s 2026 net sales) within 18-24 months. Required compliance testing impacts the time it takes to bring a product to market as well as the time necessary to retool a product and re-enter the marketplace. The Company is also at risk if trade restrictions are introduced on its products based upon country of origin. In addition, the Company may not be able to pass along most increases in tariffs and freight charges to the Company’s customers, which would directly affect profits.
