Remarks:

The transaction reported may be deemed to be matchable under Section 16(b) of the Securities Exchange Act of 1934, as amended. As noted in the Form 4 filed by the Reporting Person on February 12, 2026, Shchegolev Holdings, LLC previously contributed 144,000 shares of Issuer to an exchange traded fund (the "Fund") of which Goldman Sachs Asset Management, L.P. is the Investment Manager and Goldman Sachs EP Advisors LLC is the General Partner. In consideration of such contribution, the Reporting Person received shares of the Fund in an amount equal to the value of shares contributed ("Fund Shares"). On February 10, 2026, pursuant to the governing documents of the Fund, the Reporting Person elected to exchange the Fund Shares for the originally contributed Issuer shares, in the same amount as originally contributed (based on the closing price of the Issuer's Class A Common Stock as of market close on February 10, 2026 ($11.84), such Issuer shares had a value of $1,704,960) which were transferred back to Shchegolev Holdings, LLC. Because the sale price for the transaction in this Form 4 exceeds the closing price of the Issuer's Class A Common Stock on the date the aforementioned shares were transferred back to Shchegolev Holdings, LLC, the Reporting Person has agreed to voluntarily disgorge to Issuer any profit, as determined for purposes of Section 16(b), from these transactions.
