Encouraged by the Enthusiasm for Change Conveyed to Donerail by Fellow Shareholders

Excited to Share Comprehensive Value Creation Plan with all Shareholders Before the June Annual Meeting

Reminds Shareholders to Take Any Steps That May Be Necessary Ahead of Anticipated April 8^th Record Date to Ensure Their Shares Are Able to Be Voted

The Donerail Group LP (together with its affiliates, “Donerail,” “we” or “us”), which is one of the largest shareholders of Turtle Beach Corporation (NASDAQ: HEAR) (“Turtle Beach” or the “Company”) and, together with the other participants in its solicitation, beneficially owns approximately 8.5% of the outstanding shares of Turtle Beach, today issued the below letter to shareholders:

***

Dear Fellow Shareholders,

Since nominating an experienced, diverse, and accomplished full slate of six independent director candidates for election to the Company’s Board of Directors (the “Board”) at the Company’s 2022 Annual Meeting of Shareholders (“Annual Meeting”), we have been overwhelmed by the enthusiastic response we have received from shareholders indicating their desire for change.

Since Juergen Stark became the public company CEO of Turtle Beach, shares have underperformed the industry peer set by over 150%, EBITDA margins have been cut in half and growth has slowed to a halt.¹ All the while, we have lost faith in the ability and desire of the Board to hold management accountable for the Company’s stark underperformance and ensure the best interests of the Company’s shareholders are paramount.

Over the past year Donerail has been working diligently on a better operating plan for Turtle Beach that we believe will quickly improve profit margins, return credibility to the Board, right size the Company’s capital allocation policies, invigorate growth and fully reset the path forward.

While we look forward to beginning our work unlocking value on behalf of all shareholders, the Company seems steadfast on whitewashing its past errors, and continues to focus on misrepresenting the past engagement between us and the Board. Shareholders that we have heard from have had enough. We believe the current Board needs a reset.

The opportunity is clear. The team is set. The time is now.

Shareholders will have an opportunity to have their voices heard at the Annual Meeting coming up in June. We anticipate that the record date for the Annual Meeting is this Friday, April 8^th. We encourage shareholders to take whatever steps may be needed with their custodial banks and brokerage firms to ensure that they have the ability to vote their shares at the upcoming Annual Meeting. Turtle Beach shareholders should pay particular attention to any shares presently held in swap arrangements or in margin accounts. Donerail reminds shareholders that any shares held in margin accounts that may be loaned by a broker will need to be moved into a cash account in advance of the anticipated April 8^th record date if shareholders want to vote their shares.

As always, we are standing by to answer any questions, comments, or to hear your own suggestions on how to maximize value for all Turtle Beach shareholders. Please visit www.ResetTurtleBeach.com to learn more about the need for change at Turtle Beach.
