Each of the AE Holders is ultimately controlled by AeroEquity. AeroEquity is controlled by its managing members, Michael Robert Greene and David H. Rowe. Messrs. Greene and Rowe make all voting and investment decisions with respect to the securities held by AE Industrial Partners. AeroEquity and Messrs. Greene and Rowe may therefore be deemed to have voting and dispositive power over 30,196,088.00 shares of Common Stock directly held by the AE Holders.

The reported amounts do not include 11,168,593 shares of Common Stock beneficially owned by Dirk Wallinger. Pursuant to the Director Nomination Agreement, dated as of January 28, 2026, by and among the Issuer and the stockholders party thereto, the Reporting Persons may be deemed to be a member of a "group" within the meaning of Rule 13d-5(b) and beneficially own securities beneficially owned by Dirk Wallinger. The filing of this Statement shall not be deemed an admission of membership in any such "group" or of beneficial ownership of the securities beneficially owned by Mr. Wallinger, for purposes of Section 13(d) or 13(g) or for any other purpose. The responses to Items 5 through 9 of the cover page to this Statement do not reflect any securities beneficially owned by Mr. Wallinger.

The reported amounts also do not include an aggregate of 64,178,201 shares of Common Stock beneficially owned by parties to voting agreements (the "Voting Agreement"), by and among the Issuer and the stockholders party thereto. Pursuant to the Voting Agreements, the Reporting Persons may be deemed to be a member of a "group" within the meaning of Rule 13d-5(b) and beneficially own securities beneficially owned by the parties to the Voting Agreements. The filing of this Statement shall not be deemed an admission of membership in any such "group" or of beneficial ownership of the securities beneficially owned by such parties, for purposes of Section 13(d) or 13(g) or for any other purpose. The responses to Items 5 through 9 of the cover page to this Statement do not reflect any securities beneficially owned by parties subject to the Voting Agreements.

As a result of the foregoing, the Reporting Persons may be deemed to beneficially own an aggregate of 105,542,882 shares of Common Stock, or 81.38% of shares of Common Stock outstanding.</sharedPowerOrDirectToDispose>
