### Footnotes:

(1) On August 22, 2025, the issuer effected a 1-for-10 reverse stock split of the issued and outstanding shares of its common stock. Upon effectiveness of the reverse stock split, every 10 shares of common stock was automatically converted into one share of common stock, resulting in the reporting person's beneficial ownership of 228,222 less shares of common stock held directly.

(2) On August 22, 2025, the issuer effected a 1-for-10 reverse stock split of the issued and outstanding shares of its common stock. Upon effectiveness of the reverse stock split, every 10 shares of common stock was automatically converted into one share of common stock, resulting in the reporting person's beneficial ownership of 900 less shares of common stock held indirectly by her spouse.

(3) This option becomes exercisable as follows: (i) the portion of the stock option exercisable for one-half of the option shares (25,000 shares) will vest in three equal increments on each of the first three anniversaries of the grant date, provided Ms. Washlow remains in Orion Energy Systems, Inc.'s employment until the applicable vesting date, and (ii) the second one-half of the grant (25,000 shares) will vest, if at all, in three equal increments if the average closing sale price of Orion Energy Systems, Inc.'s common stock, for five consecutive trading days during the three calendar years immediately following the date of the grant, equals or exceeds $30.00, $40.00 and $50.00, respectively, provided Ms. Washlow remains in Orion Energy Systems, Inc.'s employment until the applicable vesting date.

(4) On August 22, 2025, the issuer effected a 1-for-10 reverse stock split of the issued and outstanding shares of its common stock. Upon effectiveness of the reverse stock split, every 10 shares of common stock was automatically converted into one share of common stock, and the number of shares subject to the reporting person's option was divided by 10, such that the option is exercisable for 450,000 less shares of common stock. Additionally, proportionate equitable adjustments were made to the exercise price of the option and the vesting requirements for the performance-vesting portion of the option.
