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
The reported exercise of 50,000 stock options underlying 50,000 shares of the Issuer's common stock was effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person on December 11, 2025 (the "10b5-1 trading plan").

The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $1.33 to $1.38, 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
The stock option to purchase one share of the Issuer's common stock for each stock option is fully vested and exercisable.
Footnote F5
Represents securities received as part of the Issuer's business combination, in connection with that certain Agreement and Plan of Merger, dated as of December 22, 2023 and amended on April 22, 2024, October 24, 2024, and November 21, 2024 (the "Merger Agreement") by and among the Issuer (formerly BurTech Acquisition Corp.), BurTech Merger Sub, Inc., Blaize, Inc. ("Legacy Blaize"), and for the limited purposes set forth therein, Burkhan Capital LLC, pursuant to which securities of Legacy Blaize were automatically converted into the right to receive stock options of the Issuer as set forth in the Merger Agreement.
Footnote F6
Corrects a typographical error in the expiration date for this stock option appearing in a Form 4 filed by the reporting person on April 8, 2026.
Footnote F7
Each restricted stock unit represents a contingent right to receive one share of the Issuer's common stock.
Footnote F8
Represents an award of restricted stock units granted at the Issuer's 2025 Annual Meeting under the Non-Employee Director Compensation Program, which vest at the earlier of one year or the Issuer's next Annual Meeting. Vested shares will be delivered to the reporting person not later than 60 days after the vesting date.
Footnote F9
These are time-based restricted stock units that vest in four equal quarterly installments commencing June 1, 2028. Vested shares will be delivered to the reporting person not later than 60 days after the vesting date.
Footnote F10
Each earnout 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. Company employees and non-employee directors who are entitled to receive earnout shares are required to provide service through the date the target is achieved and if an individual departs, the forfeited earnout shares are re-allocated among the pool of remaining eligible employees. Accordingly, the ultimate number of earnout shares is subject to adjustment from time to time in the event of forfeitures by employees of the Company, which add to the reporting person's earnout shares.
