On May 4, 2022, Turtle Beach Corporation (the “Company”) held a conference call in connection with the Company’s announcement of its earnings for the first quarter of 2022. The following excerpts from the script for the conference call contain statements that may be deemed proxy soliciting materials:

Alex Thompson – Gateway Investor Relations – IR Advisor:

“I would like to inform you that Turtle Beach Corporation has filed a definitive proxy statement and related proxy materials with the SEC in connection with the 2022 Annual Meeting of Stockholders and, in connection therewith, its directors and certain of its executive officers are participants in the solicitation of proxies from our stockholders in connection with such Annual Meeting. Stockholders of Turtle Beach are strongly encouraged to read such proxy statement and all other related materials filed with the SEC carefully and in their entirety, as they contain important information about the 2022 Annual Meeting.”

Juergen Stark – Turtle Beach Corporation – Chairman & CEO:

“The Board’s openness to value-maximizing opportunities also included our full and good faith engagement with Donerail, where we tried repeatedly to establish their financing and make their bid real and actionable. Despite our efforts, Donerail could not, or would not, verify their financing, unlike credible potential buyers. Additionally, it is important to note that feedback from multiple prospective acquirers has been that Donerail’s dissemination of false and misleading information about the Company, which started mid-2021, has unfortunately deterred and discouraged them from advancing discussions with us.

It should now be fully clear that this Board, including myself, has been and continues to be fully open to strategic alternatives if they can create shareholder value. And, as mentioned, we continue to believe that the best way to create value, whether it’s stand-alone or via strategic alternatives, is to drive the execution of our strategy to grow and diversify the business and increase earnings over time…exactly as we have done and will continue to do.”

On May 5, 2022, the Company issued a press release, a copy of which is filed herewith as Exhibit A. Also on May 5, 2022, the Company made certain updates to its website relating to the upcoming 2022 annual meeting of stockholders, https://voteturtlebeach.com. Updated screenshots of the website are filed herewith as Exhibit B.

Important Additional Information

STOCKHOLDERS OF THE COMPANY ARE STRONGLY ENCOURAGED TO READ SUCH PROXY STATEMENT, ACCOMPANYING BLUE PROXY CARD AND ALL OTHER DOCUMENTS FILED WITH THE SEC CAREFULLY AND IN THEIR ENTIRETY AS THEY CONTAIN IMPORTANT INFORMATION.

Exhibit A

Turtle Beach Board of Directors Issues Open Letter to Stockholders Highlighting Record of

Proactive Engagement with Potential Acquirers

Board Remains Openminded to All Credible Opportunities to Maximize Value

WHITE PLAINS, N.Y. – May 5, 2022 – Leading gaming accessory maker Turtle Beach Corporation (Nasdaq: HEAR) (“Turtle Beach” or the “Company”) today issued the following open letter to stockholders from its Board of Directors:

Dear Fellow Stockholders,

We hope you had the opportunity to listen to our first quarter 2022 earnings call yesterday, a replay of which is available on our investor relations website. The Board is serious and proactive in its duty to consider all credible opportunities to maximize value, and we wanted to reiterate some of the details provided with respect to our approach to strategic alternatives.

As noted on the call, we have engaged in banker-led, proactive outreach processes to potential acquirers on three separate occasions in the past five years. The most recent of those efforts began when we retained a banker in late 2020 to engage in outreach to third parties starting in early 2021. We subsequently made the decision in the Spring of 2021 to switch bankers and engaged Bank of America to continue our efforts and, since then, we have been in contact with 29 potential acquirers, comprising the most logical potential strategic buyers as well as select financial sponsors. Based on that outreach, we signed 10 NDAs and held 9 management meetings. As is always the case, there is no guarantee that discussions of this nature will result in a transaction.

We received feedback from prospective buyers and their advisors throughout the course of this extensive engagement. In several cases we heard that potential buyers were unwilling to move forward because Turtle Beach had too much reliance on console gaming headsets and the cyclicality that comes with that, which is consistent with the feedback we received in prior rounds of outreach. This is one of the many reasons we have pursued our value-creating diversification strategy.

It is also important to reiterate that in the prior two rounds of outreach we received bids that would have been unattractive to our stockholders. In both cases, our stock price was trading at low levels based on overall market conditions, and the offers undervalued Turtle Beach. We subsequently drove higher value for stockholders than the bids offered. This is, in part, why we believe that the right course of action is to continue executing our strategy, which we believe will enhance value in the context of either a standalone entity or in a potential transaction.

The Board’s openness to value-maximizing opportunities was also clear in our full and good faith engagement with Donerail, where Turtle Beach repeatedly tried to establish Donerail’s financing in order to make their bid real and actionable. Despite our efforts, Donerail could not, or would not, verify their financing, unlike other credible potential buyers. Furthermore, the proxy contest being waged by the Donerail Group to gain control of Turtle Beach, and the Donerail Group’s dissemination of false and misleading information about the Company, which began mid-2021, has unfortunately deterred and discouraged multiple potential acquirers based on feedback we’ve received directly from these parties.

The Turtle Beach Board stands firmly committed to executing on its fiduciary duty and acting in the best interest of ALL stockholders. The Board continues to believe that the best way to create value, whether as a stand-alone entity or through strategic alternatives, is to continue to execute on a strategy that grows the business and grows and diversifies earnings over time.

Do not risk the value of your investment by letting Donerail jeopardize the incredible momentum underway. If Donerail’s hand-picked nominees are elected, we believe Turtle Beach would be forced to execute a rushed fire-sale of the Company that would be value destructive to Turtle Beach stockholders.

To protect the value of your investment and ensure Turtle Beach is positioned to achieve maximum value from any potential future transaction, we urge you to vote the BLUE proxy card “FOR” all of Turtle Beach’s director nominees: Juergen Stark, Greg Ballard, Yie-Hsin Hung, William Keitel, Kelly Thompson, and Dr. Andrew Wolfe.

We look forward to engaging with stockholders directly in the coming weeks and to continuing to work on your behalf to drive enhanced value.

Thank you for your support.

Sincerely,

Your Turtle Beach Board of Directors
