Departure of Chief Financial Officer

On June 15, 2026, Matternet, Inc. (“Matternet”) filed a Current Report on Form 8-K with the Securities and Exchange Commission (the “SEC”), disclosing that we and Jason Secore, our Chief Financial Officer, had mutually agreed to begin a transition with respect to his responsibilities. On September 28, 2026, we filed a Current Report on Form 8-K disclosing that Mr. Secore’s employment with Matternet would end on September 29, 2026, and we had commenced a search for Mr. Secore’s successor. Mr. Secore’s departure was not related to any disagreement with Matternet regarding our operations, policies or practices.

On October 1, 2026, we entered into a separation agreement with Mr. Secore pursuant to which we will pay Mr. Secore a cash amount of $156,146, and we agreed to extend the post-termination exercise period of Mr. Secore’s equity awards until the 18-month anniversary of the date our common stock is first listed on any market tier of The Nasdaq Stock Market LLC, the New York Stock Exchange or NYSE American (the “Post-Termination Period”). Mr. Secore agreed that during the Post-Termination Period he will be available for periodic consultations with our Chief Executive Officer with respect to company matters. The separation agreement is filed as Exhibit 10.1 to this Current Report on Form 8-K.
