Form 10-K Summary 62 EXHIBIT INDEX 63 SIGNATURES 65 1 PART I Statement Regarding Forward-Looking Disclosures This Annual Report on Form 10-K (this “Report”) includes, and incorporates by reference, certain forward-looking statements within the meaning of the federal securities laws. Statements that are not historical facts, including statements about our beliefs and expectations, are forward-looking statements. Forward-looking statements include statements preceded by, followed by, or that include the words “may,” “could,” “will,” “would,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “intend,” “predict,” “seek,” “contemplate,” “potential,” “continue,” and similar expressions. These forward- looking statements reflect the current expectations of Turtle Beach Corporation concerning future events, and actual results may differ materially from current expectations or historical results. Any such forward-looking statements are subject to various risks and uncertainties, including without limitation those discussed in the sections of this Report entitled “Business Overview,” “Risk Factors,” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Forward-looking statements are only predictions and are not guarantees of performance. These statements are based on our management’s beliefs and assumptions, which in turn are based on currently available information. Important assumptions relating to the forward-looking statements include, among others, assumptions regarding demand for our products, the expansion of product offerings geographically or through new marketing applications, the timing and cost of planned capital expenditures, competitive conditions, and general economic conditions. These assumptions could prove inaccurate. Forward-looking statements also involve known and unknown risks and uncertainties, which could cause actual results to differ materially from those contained in any forward-looking statement. In addition, even if our actual results are consistent with the forward-looking statements contained in this Report, those results may not be indicative of results or developments in subsequent periods. Many of these factors are beyond our ability to control or predict. Such factors include, but are not limited to, the following: • Our dependence on the success and availability of third-party platforms and software to drive sales; • Transitions in video gaming console platforms and the potential impact on our business; • Our ability to adapt to new technologies and introduce new products on a timely basis; • The impact of competitive products, technologies and pricing; • Continued relationships with our largest customers and the emergence of new customers; • The impact of seasonality on our business; • Global business, political, operational, financial and economic conditions; • Our ability to forecast demand for our products; • Manufacturing capacity and/ or component supply constraints and difficulties; • The scope of protection we are able to establish and maintain for intellectual property rights covering our technology; • The availability of capital under our revolving credit facility; • Estimates of our future revenues, expenses, capital requirements, and our needs for additional financing; • Cybersecurity and other information technology risks; • The Company’s partnerships with influencers, athletes and esports teams; • Our financial performance; and • Other factors discussed under Item 1A - Risk Factors, or elsewhere in this Report. Except as required by applicable law, including the securities laws of the United States and the rules and regulations of the Securities and Exchange Commission (“SEC”), we undertake no obligation to publicly update or revise any forward-looking statements after we file this Annual Report on Form 10-K, whether as a result of any new information, future events or otherwise. Investors, potential investors, and other readers are urged to consider the above mentioned factors carefully in evaluating the forward‑looking statements and are cautioned not to place undue reliance on such forward‑looking statements. Although we believe that the expectations, reflected in the forward-looking statements are reasonable, we cannot guarantee future results or performance. Unless the context indicates otherwise, all references in this Report to “we,” “our,” “us,” “the Company,” and “Turtle Beach” refer to Turtle Beach Corporation and its wholly-owned subsidiaries. 2 Item 1 - Business Overview Turtle Beach Corporation’s
