Drilling Tools International Corp. Reports 2025 Year End and Fourth Quarter Results

Expects Continued Growth in 2026 Consolidated Revenue, Adjusted EBITDA and Adjusted Free Cash Flow

Drilling Tools International Corp., (NASDAQ: DTI) (“DTI” or the “Company”), a global oilfield services company that designs, engineers, manufactures and provides a differentiated, rental-focused offering of tools for use in onshore and offshore horizontal and directional drilling operations, as well as other cutting-edge solutions across the well life cycle, today reported its results for the twelve months and fourth quarter ended December 31, 2025.

For the twelve months of 2025, DTI generated total consolidated revenue of $159.6 million. 2025 Tool Rental revenue was $129.6 million and Product Sale revenue totaled approximately $30.1 million. Net Loss attributable to shareholders for 2025 was a loss of approximately $3.8 million or a loss of $0.11 per share. Adjusted Net Income(1) and Adjusted Diluted EPS(1) for 2025 were $3.4 million and $0.10 per diluted share, respectively. Adjusted EBITDA(1) was $39.3 million and Adjusted Free Cash Flow(1)(2) was $19.2 million. As of December 31, 2025, DTI had $3.6 million of cash and cash equivalents, and net debt of $42.2 million.

For the fourth quarter of 2025, DTI generated total consolidated revenue of $38.5 million. Fourth quarter Tool Rental revenue was $30.4 million, and Product Sales revenue totaled approximately $8.1 million. Net Income attributable to common stockholders for the fourth quarter was $1.2 million or $0.03 per share. Adjusted Net Income(1) was $1.5 million and Adjusted Diluted EPS(1) for the fourth quarter was $0.04 per diluted share, respectively. Fourth quarter Adjusted EBITDA(1) was $10.1 million and Adjusted Free Cash Flow(1)(2) was $6.1 million.

Wayne Prejean, President, Chief Executive Officer, and interim Chairman of the Board of Directors of DTI, stated, “Our strong fourth quarter results demonstrate our ability to consistently deliver favorable returns in the face of muted industry-wide activity levels. With the help of more moderate seasonality and budget exhaustion than historical trends would have indicated, we exceeded our internal expectations for the quarter and again generated meaningful free cash flow. Despite global rig count declining nearly 7% in 2025, we are pleased that our consistent operational performance and our team's ability to adapt to the ever-changing market environment enabled us to achieve the high-end of our guidance ranges. In addition, we have now grown annual free cash flow every year since going public, an achievement we take great pride in. This is a testament to the organization that we have built, the efficiency with which we operate and the significant demand for our tools.

“We also demonstrated prudent capital discipline in 2025 by simultaneously reducing debt and returning capital to shareholders through share buybacks. When the market softened mid-year, we were able to shift our focus away from growth capital expenditures and prioritize harvesting our cash flow. Leveraging this flexibility allowed us to pay down over $11 million of debt in the second half of the year and buy back, approximately, an additional $660,000 of common shares over the same period. This strategic decision brought down our net debt to trailing twelve-month Adjusted EBITDA multiple to a conservative 1.1x, even after recently completing four acquisitions,” added Prejean.

“Throughout 2025, our Eastern Hemisphere operations experienced immense growth. This segment nearly doubled its revenue contribution to 14% of our total revenue, and we aim to build on this momentum in 2026. We continue to believe that the downhole drilling tool industry remains fragmented, is in need of consolidation, and we intend to continue being part of the solution. The energy landscape is constantly evolving, and we plan to actively pursue deals that improve our standing within the market.

“Looking forward, we expect overall activity, particularly in the first half of 2026, to remain relatively soft. However, we have identified several potential catalysts across multiple geographies that offer upside potential in the back half of the year. We have completed four acquisitions within the last 24 months and have added industry leading tools and technological solutions while penetrating new markets. This positions us well to generate resilient results despite the subdued US Land market conditions, and as anticipated activity levels improve, we expect that the work we have done to strengthen DTI will deliver meaningful financial improvement. As an indication of the solid foundation we have built, we are introducing our 2026 outlook ranges that reflect year-over-year growth at the midpoint,” concluded Prejean.

2026 Full Year Outlook

Revenue $155 million $170 million Adjusted EBITDA(1) $35 million $45 million Adjusted EBITDA Margin(1) 23 % 26 % Adjusted Free Cash Flow(1)(2) $17 million $22 million (1) Adjusted Net Income (Loss), Adjusted Diluted EPS, Adjusted EBITDA, Adjusted EBITDA Margin, Net Debt, and Adjusted Free Cash Flow are non-GAAP financial measures.

Non-GAAP Financial Measures

This release includes Adjusted EBITDA, Adjusted Free Cash Flow, Net Debt, Adjusted Basic Earnings (Loss) Per Share, Adjusted Diluted Earnings (Loss) Per Share and Adjusted Net Income (Loss) measures. Each of the metrics are “non-GAAP financial measures” as defined in Regulation G of the Securities Exchange Act of 1934.

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies. Adjusted EBITDA is not a measure of net earnings or cash flows as determined by GAAP. We define Adjusted EBITDA as net earnings (loss) before interest, taxes, depreciation and amortization, further adjusted for (i) goodwill and/or long-lived asset impairment charges, (ii) stock-based compensation expense, (iii) restructuring charges, (iv) transaction and integration costs related to acquisitions and (v) other expenses or charges to exclude certain items that we believe are not reflective of ongoing performance of our business.

We believe Adjusted EBITDA and Adjusted EBITDA Margin is useful because it allows us to supplement the GAAP measures in order to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP, or as an indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing a company's financial performance, such as a company's cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDA. Our computations of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies.

Adjusted Free Cash Flow is a supplemental non-GAAP financial measure, and we define Adjusted Free Cash Flow as Adjusted EBITDA less Gross Capital Expenditures. We use Adjusted Free Cash Flow as a financial performance measure used for planning, forecasting, and evaluating our performance. We believe that Adjusted Free Cash Flow is useful to enable investors and others to perform comparisons of current and historical performance of the Company. As a performance measure, rather than a liquidity measure, the most closely comparable GAAP measure is net income (loss).

Net Debt is a supplemental non-GAAP financial measure, and we define Net Debt as total debt less cash and cash equivalents. We use Net Debt to determine our outstanding debt obligations that would not be readily satisfied by our cash and cash equivalents on hand. We believe this metric is useful to analysts and investors in determining our leverage position since we have the ability to, and may decide to, use a portion of our cash and cash equivalents to reduce debt.

We define Adjusted Net Income (Loss) as consolidated net income (loss) adjusted for (i) goodwill and/or long-lived asset impairment charges, (ii) restructuring charges, (iii) transaction and integration costs related to acquisitions, (iv) income taxes expense which is calculated by applying our effective tax rate on unadjusted net income to adjusted pre-tax income, and (v) other expenses or charges to exclude certain items that we believe are not reflective of the ongoing performance of our business. We believe Adjusted Net Income (Loss) is useful because it allows us to exclude non-recurring items in evaluating our operating performance.

We define Adjusted Basic Earnings (Loss) and Adjusted Diluted Earnings (Loss) per share as the quotient of adjusted net income (loss) and diluted weighted average common shares. We believe that Adjusted Diluted Earnings (Loss) per share provides useful information to investors because it allows us to exclude non-recurring items in evaluating our operating performance on a diluted per share basis.

This release also includes certain projections of non-GAAP financial measures. Reconciliation of these items to net income include gains or losses on sale or consolidation transactions, accelerated depreciation, impairment charges, gains or losses on retirement of debt, variations in effective tax rate and fluctuations in net working capital, which are difficult to predict and estimate and are primarily dependent on future events.

The following tables present a reconciliation of the non-GAAP financial measures of Adjusted EBITDA, Adjusted Free Cash Flow and Adjusted Net Income to the most directly comparable GAAP financial measures for the periods indicated:
