Subject:  A Message From Eargo CEO Christian Gormsen

A transcript of the above video can be viewed at the bottom of this email.

Dear Stockholder,

I am reaching out to you because your vote is critical.

As I explained in the video you just watched, we need the approval of stockholders on two key proposals in order to conduct our proposed rights offering and fulfill our agreement with Patient Square Capital. Eargo and its Board of Directors urge stockholders to vote FOR Proposal Five and Proposal Six.

If the Company does not receive a majority stockholder vote for proposals five and six, we will be unable to complete the Rights Offering and, as a result, be in default under our Note Purchase Agreement with Patient Square Capital. A default could result in stockholders losing all or substantially all of their investment in our common stock. We need stockholders to vote FOR the proposals to help ensure this does not happen.

We urge you to vote as soon as possible ahead of our 2022 Annual Meeting of Stockholders to be held on October 12, 2022 at 11 A.M. Pacific Time. You can vote easily using the voting link within this email. For assistance with voting your shares you can call Morrow Sodali, our proxy solicitor, at (877) 787-9239, or send a message to EAR.info@investor.morrowsodali.com.

Please visit our website here for more information on the rights offering, Proposals Five and Six, the other proposals and how to vote. We also urge all stockholders to read our Definitive Proxy Statement, which was mailed to all stockholders on or about September 14, 2022 and is available on our investor relations website.

Thank you so much for your time and continued support of Eargo.

Sincerely,

Christian

Video Transcript:

Hi, I’m Christian Gormsen, President and CEO of Eargo.  And I’m excited to speak with you today about our annual meeting on October 12th and the importance that you, as a stockholder, vote on a number of critical proposals that are key to the Company’s future.  Specifically, we urge stockholders to vote FOR Proposals Five and Six.

As a brief background for Proposals Five and Six, in June of 2022, we closed a $100 million convertible note financing with Patient Square Capital that is providing critical capital allowing us to focus on our core business initiatives.

The notes are a form of debt that must be repaid or converted.  That debt is secured against the Company’s assets.  The Note Purchase Agreement provides that we must complete what is called a Rights Offering by December 24, 2022.  The proceeds from the Rights Offering will be used to repay Patient Square’s notes at a premium, and any notes not repaid would be converted into shares of the Company.  Importantly, the rights offering gives our existing stockholders the opportunity to purchase their pro rata share of 375 million newly issued shares of our common stock at a purchase price of $0.50 per share.  The Rights Offering will allow stockholders to participate in financing the Company and avoid a reduction in their percentage shareholdings of the Company.

Here’s why - Depending on the level of stockholder participation in, and the timing of, the offering, Patient Square may end up owning as much as 90.5% of the Company if no stockholders participate in the offering, or not own any of the Company if stockholders purchase all 375 million shares.

Following the completion of the Rights Offering, the Company will have no debt on its balance sheet.

Here’s where your vote is critical – in order to complete the Rights Offering, we need the approval of stockholders on two key proposals.  Eargo and its Board of Directors urge stockholders to vote FOR Proposal Five and Proposal Six.

If the Company does not receive a majority stockholder vote for proposals five and six, we will be unable to complete the Rights Offering and, as a result, be in default under our Note Purchase Agreement with Patient Square.  In that scenario, Patient Square could demand immediate repayment of the Notes.  Since we do not believe we would have the cash to make that repayment, Patient Square could begin seizing the company’s assets and stockholders would likely lose all or substantially all of their investment in our common stock.  We need stockholders to vote FOR the proposals to help ensure this does not happen.

Please see our voting web site for more information on the Rights Offering, Proposals Five and Six, the other proposals and how to vote.

For more information, including a multi-scenario analysis of possible outcomes, please review our Definitive Proxy Statement, which was mailed to all stockholders on or about September 14, 2022 and is available on our investor relations website.

Thank you so much for your time and continued support of Eargo.
