Additional SEC filing notes
Filing notes and footnotes
Rule 10b5-1 trading plan
These transactions were reported as open-market trades under a Rule 10b5-1 plan. The plan lets an insider set trading instructions in advance, which can reduce the risk of trading while in possession of material nonpublic information.
Original filing language: transaction made pursuant to a contract, instruction, or written plan intended to satisfy Rule 10b5-1(c).
Explanation of responses 10 footnotes
Footnote F1
On April 20, 2026, the reporting person filed a Form 4 (the "Original Form 4") which inadvertently reported that the reporting person exercised a stock option and sold the underlying stock. Instead, as reported in this amendment (this "Amendment"), the reporting person did not exercise the stock option and in fact sold the same number of shares of stock as originally reported in the Original Form 4 but from his Table I holdings. The reporting person's other holdings have been restated for convenience, and there have been no transactions in such holdings since the Original Form 4. The order of the footnotes in this Explanation of Responses section have been conformed to the above changes.
Footnote F2
The reported sales were effected pursuant to the reporting person's Rule 10b5-1 trading plan adopted by the reporting person on December 12, 2025.
Footnote F3
The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $2.50 to $2.63, inclusive. Upon request by the SEC staff, the Issuer, or any security holder of the Issuer, full information regarding the number of shares sold at each separate price will be provided.
Footnote F4
In the reporting person's prior Form 4 filings, earnout shares and unvested restricted stock units had been reported in Table I. These holdings have been moved to Table II, and there have been no transactions in such holdings since the reporting person's last Form 4 filing.
Footnote F5
The stock option vests in 36 substantially equal monthly installments beginning on October 19, 2023.
Footnote F6
Each restricted stock unit represents a contingent right to receive one share of the Issuer's common stock.
Footnote F7
The restricted stock units vest 25% on December 1, 2027, and quarterly thereafter commencing on March 1, 2028.
Footnote F8
On January 13, 2025, the date of the Issuer's business combination, the reporting person received earnout shares in respect of the Issuer's business combination. Each eanout share represents a contingent right to receive one share of the Issuer's common stock if the trading price of the Issuer's common stock exceeds certain thresholds for 20 of 30 consecutive trading days post-closing of the Issuer's business combination.
Footnote F9
The stock option vests as to one third of the underlying shares on July 1, 2025 and thereafter in 24 equal monthly installments.
Footnote F10
The stock option to purchase one share of the Issuer's common stock for each stock option is fully vested and exercisable.
