F1

Each RSU represents a contingent right to receive one share of the Company common stock.

F2

The RSUs vest in substantially equal installments on each of the first four (4) anniversaries of the grant date, February 28, 2025.

F3

On February 27, 2026, the reporting person was granted 85,721 RSUs under the Company's 2023 Omnibus Incentive Plan, as may be amended from time to time (the "Plan"), pursuant to the 2026 long-term incentive program approved by the Board of Directors (the "2026 LTIP"). The RSUs vest in substantially equal installments on each of the first three (3) anniversaries of the grant date, subject to continued service.

F4

Each performance stock unit ("PSU") represents a contingent right to receive one share of the Company's common stock.

F5

On February 27, 2026, the reporting person was granted 257,162 PSUs under the Plan, pursuant to the 2026 LTIP. The PSUs are subject to the achievement of performance conditions based on EBITDA, weighted at 100%, with annual reset over a three-year performance vesting period. Achievement at threshold results in a 50% payout opportunity, while achievement at maximum results in a 200% payout opportunity.

F6

Two-thirds (2/3) of the stock options have vested in substantially equal installments on each of the first two (2) anniversaries of the grant date, with the remaining one-third (1/3) scheduled to vest on the third (3rd) anniversary of the grant date, February 14, 2024.

F7

All shares of common stock subject to the stock options are vested.

Remarks

The Reporting Person may be deemed to have voting power and dispositive power over the shares held by Robjon Holdings, L.P. ("Robjon"). The Reporting Person is the President, Manager and sole owner of Robjon LLC, Robjon's general partner. The Reporting Person disclaims any beneficial ownership of any shares of common stock held by Robjon, other than his pecuniary interest therein.; On March 12, 2026, the reporting person filed a Form 4 which inadvertently reported that, following the vesting of restricted stock units ("RSUs"), he retained 71,090 shares of common stock. In fact, as reported in this amendment, 18,543 shares were withheld by Drilling Tools International Corp (the "Company") to pay for taxes. The corrected amount is reflected in this amendment.
