  1. This transaction was completed pursuant to a Rule 10b5-1 trading plan adopted by the reporting person on November 17, 2025. Each restricted stock unit ("RSU") represents a contingent right to receive one share of Drilling Tools International Corp's (the "Company") common stock. The RSUs vest in substantially equal installments on each of the first four (4) anniversaries of the grant date, February 28, 2025. On February 27, 2026, the reporting person was granted 22,859 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.

Rule 10b5-1 trading plan financial
"This transaction was completed pursuant to a Rule 10b5-1 trading plan adopted by the reporting person"
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
restricted stock unit financial
"Each restricted stock unit ("RSU") represents a contingent right to receive one share"
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
performance stock unit financial
"Each performance stock unit ("PSU") represents a contingent right to receive one share"
A performance stock unit is a type of reward companies give to employees, usually managers, that depends on how well the company performs over time. If the company hits specific goals, the employee earns shares of stock, like earning a prize for reaching certain levels in a game. It motivates employees to work hard because their rewards are tied to the company's success.
2026 long-term incentive program financial
"pursuant to the 2026 long-term incentive program approved by the Board of Directors"
EBITDA financial
"The PSUs are subject to the achievement of performance conditions based on EBITDA, weighted at 100%"
EBITDA stands for earnings before interest, taxes, depreciation, and amortization. It measures a company's profitability by focusing on the money it makes from its core operations, ignoring expenses like taxes and accounting adjustments. Investors use EBITDA to compare how well different companies are performing financially, as it provides a clearer picture of operational success without the influence of financial structure or accounting choices.
Omnibus Incentive Plan financial
"under the Company's 2023 Omnibus Incentive Plan, as may be amended from time to time"
An omnibus incentive plan is a single, flexible program a company uses to give employees and executives different types of pay tied to performance — for example stock options, restricted shares, cash bonuses and other awards — all governed by one set of rules. It matters to investors because it determines how many new shares may be created, how leaders are motivated and how much the company will spend on compensation over time; think of it as a master toolbox that affects both costs and the total share supply.
