The execution prices were as follows: 01/23/2026: $1.47 to $1.48, inclusive; 01/27/2026: $1.46 to $1.49, inclusive; 02/05/2026: $1.43 to $1.45, inclusive; 03/17/2026: $1.3099 to $1.31, inclusive. The Reporting Person undertakes to provide IRIDEX CORP, any security holder of IRIDEX CORP, or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares purchased at each separate price within the ranges set forth above.

Footnote F3

As of the date of this report, the Reporting Person beneficially owns an aggregate of 1,738,238 shares of Common Stock, consisting of 1,186,809 shares held through Xinpo and 551,429 shares held through Novel Inspiration International Co., Ltd.("Novel Inspiration").

SEC remarks

This Form 4 is the third of three Form 4 filings being filed solely by the Reporting Person to report previously unreported open-market purchases of the Issuer's Common Stock by Xinpo from March 25, 2025 through March 30, 2026. The transactions are divided among three Form 4 filings because SEC's EDGAR filing system permits no more than 30 entries in Table I. The Reporting Person's holdings through Novel Inspiration are disclosed in the Explanation of Responses solely to reconcile the Reporting Person's aggregate beneficial ownership and do not represent transactions reported on this Form 4. This Form 4 is being filed late.
