SAN DIEGO, CA – August 7, 2025 – Turtle Beach Corporation (Nasdaq: TBCH, the “Company”), a leading gaming accessories brand, today reported financial results for the quarter ended June 30, 2025 and reiterated full year guidance for revenue and Adjusted EBITDA.

Second Quarter Highlights

“I'm pleased to report Turtle Beach’s continued execution in a dynamic economic environment,” said Cris Keirn, Chief Executive Officer, Turtle Beach Corporation. “Our second quarter results and confirmation of full year guidance reflects our organization’s agility in navigating the current challenges in the macro environment and gaming accessories markets. The swift actions we have taken on our ongoing cost optimization initiatives and rapid adaptation of our production strategy have significantly mitigated tariff impacts on our business. Year-over-year gross margin for the quarter improved to over 32% despite an approximate 150 basis point negative impact from tariffs. With the improvements seen in markets for Q2 expected to continue into the second half of the year, we expect revenue and profitability to recover in support of our full year guidance."

“Additionally, our recent strategic refinancing has meaningfully improved our cost of capital with reduced interest rates and enhanced financial flexibility, enabling us to continue investing in long-term growth while enhancing shareholder value. Looking ahead, we're encouraged by the market improvements we’re seeing in the gaming accessories space, and we remain well-positioned to capitalize on key industry growth drivers into 2026.”

Debt Refinancing

Last week, Turtle Beach Corporation announced the refinancing of the Company’s existing debt facilities. The new $150 million facility is comprised of a $90 million revolving credit facility and a $60 million term loan. This significant milestone strengthens the Company’s capital structure through a lowered cost of capital and enhanced financial flexibility. Under the terms of the new loan agreement, Turtle Beach has lowered its cost of capital on the term loan by approximately 450 basis points relative to the prior term loan, resulting in an annual dollar cost savings of over $2.0 million. Additionally, this refinancing revises certain prior operational limitations, including on the Company’s ability to repurchase shares.

Share Repurchase Update

For the second quarter ended June 30, 2025, Turtle Beach Corporation repurchased $5.0 million of common stock under the recently announced $75 million share repurchase agreement. With the Company’s continued commitment to return capital to shareholders, and the enhanced flexibility to repurchase shares under the new debt agreements, Turtle Beach intends to remain opportunistic in share buybacks moving forward.

Financial Outlook

Turtle Beach Corporation is reiterating its financial outlook for the full year 2025. The Company currently expects net revenues in the range of $340 million and $360 million and Adjusted EBITDA in the range of $47 million and $53 million.

Non-GAAP Financial Measures

In addition to its reported results, the Company has included in this earnings release certain financial metrics, including Adjusted EBITDA, that the Securities and Exchange Commission define as “non-GAAP financial measures.” Management believes that such non-GAAP financial measures, when read in conjunction with the Company’s reported results, can provide useful supplemental information for investors analyzing period-to-period comparisons of the Company’s results. Non-GAAP financial measures are not an alternative to the Company’s GAAP financial results and may not be calculated in the same manner as similar measures

presented by other companies. “Adjusted EBITDA” is defined by the Company as net income (loss) before interest, taxes, depreciation and amortization, stock-based compensation (non-cash), and certain non-recurring special items that we believe are not representative of core operations, as further described in Table 4. These non-GAAP financial measures are presented because management uses non-GAAP financial measures to evaluate the Company’s operating performance, to perform financial planning, and to determine incentive compensation. Therefore, the Company believes that the presentation of non-GAAP financial measures provides useful supplementary information to, and facilitates additional analysis by, investors. The non-GAAP financial measures included herein exclude items that management does not believe reflect the Company’s core operating performance because such items are inherently unusual, non-operating, unpredictable, non-recurring, or non-cash. See a reconciliation of GAAP results to Adjusted EBITDA included as Table 4 below for the three and six months ended June 30, 2025, and June 30, 2024.

By providing full year 2025 Adjusted EBITDA guidance, the Company provided its expectation of a forward-looking non-GAAP financial measure. Information reconciling full year 2025 Adjusted EBITDA to its most directly comparable GAAP financial measure, net income (loss), is unavailable to the Company without unreasonable effort due to the variability, complexity, and lack of visibility with respect to certain reconciling items between Adjusted EBITDA and net income (loss), including other income (expense), provision for income taxes and stock-based compensation. These items cannot be reasonably and accurately predicted without the investment of undue time, cost and other resources and, accordingly, a reconciliation of the Company’s Adjusted EBITDA outlook to its net income (loss) outlook for such periods is not provided. These reconciling items could be material to the Company’s actual results for such periods.
