NOTE 11 – STOCK-BASED COMPENSATION

On June 20, 2023, the Company adopted the Drilling Tools International Corporation 2023 Omnibus Incentive Plan (the "2023 Plan"). The 2023 Plan became effective on the closing of the Merger. The 2023 Plan provides for the issuance of shares of Common Stock up to ten percent (10%) of the shares of outstanding Common Stock as of the closing of the Merger and automatically increases on the first trading day of each calendar year by the number of shares of Common Stock equal to three percent (3%) of the total number of outstanding Common Stock on the last day of the prior calendar year. The 2023 Plan allows for awards to be issued to employees, non-employee directors, and consultants in the form of options, stock appreciation rights, restricted shares, restricted stock units, performance based awards, other share-based awards, other cash-based awards, or a combination of the foregoing. As of December 31, 2025, there were 1,580,395 shares of Common Stock available for issuance under the 2023 Plan.

Stock Options

The stock options issued are service based with a vest term ranging from one to three years. The awards have contractual terms of ten years. The fair value of each stock option award is estimated on the date of grant using a Black-Scholes model. Expected

volatilities are based on comparable public company data. The Company uses future estimated employee termination and forfeiture rates of the options within the valuation model. The expected term of options granted is derived using the “plain vanilla” method due to the lack of history and volume of option activity at the Company. The risk-free rate is based on the approximate U.S. Treasury yield rate in effect at the time of grant. The Company will use the quoted market price as of the grant date as an input into the Black-Scholes model.

During the years ended December 31, 2025 and 2024, the Company recognized $1.5 million and $1.4 million, respectively, of stock-based compensation expense related to stock options within selling, general, and administrative expenses on the consolidated statements of comprehensive income (loss). As of December 31, 2025, total unrecognized compensation expense related to the stock options totaled $1.6 million.

Restricted Stock Units

Restricted stock units ("RSUs") are granted employees as well as members of the Board of Directors. RSUs vest over a one to four year period with service and continued employment as the only vesting criteria. The recipient of the restricted stock award is entitled to all of the rights of a shareholder, except that the award is nontransferable during the vesting period. The fair value of the restricted stock award is established on the grant date and then expensed over the vesting period resulting in an increase in additional paid-in-capital.

During the years ended December 31, 2025 and 2024, the Company recognized $1.0 million and $0.7 million, respectively, of stock based compensation related to RSUs within selling, general, and administrative expenses on the consolidated statements of comprehensive income (loss). As of December 31, 2025, unrecognized compensation expense related to the RSUs totaled $2.4 million.
