2022 Equity Incentive Plan

On January 24, 2022 the CSI board of directors adopted, and on March 16, 2022 the Company’s shareholders approved, the Company’s 2022 Equity Incentive Plan (“2022 Plan”), which became effective on March 28, 2022.

At March 31, 2025, 4 shares had been issued under the 2022 Plan, 3 shares were subject to currently outstanding unvested restricted stock units (“RSUs”), and 60 shares were available for grant under future awards.

Employee Stock Purchase Plan

On December 7, 2022, the Company’s shareholders approved an Employee Stock Purchase Plan (“ESPP”), pursuant to which eligible employees are able to acquire shares of common stock at a purchase price determined by the board of directors or compensation committee prior to the start of each six-month plan phase, which price may not be less than 85% of the fair market value of the lower of the value on the first day or the last day of the phase, or the value on the last day of the phase. The ESPP is considered compensatory under current Internal Revenue Service rules. At March 31, 2025, 2 shares remained available for purchase under the ESPP.
