Explanatory Note

On June 15, 2026, Innovex International, Inc., a Delaware corporation (the “Company” or "Innovex"), entered into a Share Purchase Agreement (the “Purchase Agreement”) with Rieber & Søn AS, a Norwegian private limited liability company (the “Seller”), pursuant to which the Company agreed to acquire from the Seller all of the issued shares (other than treasury shares) of TCO Group AS, a Norwegian private limited liability company (“TCO Group”). TCO Group is engaged in the development, manufacturing, and supply of equipment, tools, and related services to the oil and gas industry. TCO Group’s product offering includes completion barrier plugs, tubing-conveyed perforating services, chemical injection systems and annulus pressure relief systems. These products are used in well completion and testing, perforation services, targeted downhole chemical delivery and automatic relief of trapped pressure between casing strings.

The aggregate purchase price (the “Purchase Price”) is equal to the Norwegian krone equivalent of approximately $95 million. The Purchase Price is comprised of the following components: (i) $30 million in newly-issued shares (the “Consideration Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”), with the newly-issued shares priced based on the average of the volume weighted average trading prices (“VWAP”) of the Common Stock on the New York Stock Exchange for the fifteen trading days immediately preceding June 15, 2026, which is approximately $28.20, resulting in the issuance of approximately 1,063,829 Consideration Shares, and (ii) $65 million in cash, subject to certain adjustments. Closing of the transactions contemplated by the Purchase Agreement is expected to occur early in the third quarter of 2026, subject to customary closing conditions.

The Seller and its wholly owned Singapore subsidiary, Rieber & Son Pte. Ltd. (the designated recipient of the Consideration Shares) have agreed not to offer, sell or otherwise transfer any of the Consideration Shares for a period of six months after the closing date of the transactions contemplated by the Purchase Agreement, except that Consideration Shares may be transferred to a wholly owned subsidiary, provided that the transferee remains subject to the same lock-up restrictions and may not subsequently transfer the shares during the lock-up period.

For the fiscal year ended December 31, 2025, TCO Group’s revenue, operating income and net income were approximately $70 million, $16 million and $12 million, respectively, resulting in an 18% net income margin. TCO Group also had $12 million of cash flow from operations for the fiscal year ended December 31, 2025, and TCO Group’s capital expenditures were approximately $0.2 million and represented less than 1% of its revenue for that period.

For the fiscal year ended December 31, 2025, TCO Group had Adjusted EBITDA of $18 million, Adjusted EBITDA Margin of 25%, and Free Cash Flow of $11 million. The Company’s Transaction Return on Capital Employed (“Transaction ROCE”) for the acquisition is expected to be 14% based on TCO Group’s 2025 operating income of $16 million less tax expense of approximately $3 million divided by the $95 million Purchase Price.

The transaction is expected to be approximately 13% accretive to Innovex’s Earnings Per Share (“EPS”), based on the approximate percentage increase in basic EPS of Innovex for the year ended December 31, 2025 as if the acquisition had occurred on January 1, 2025, which is calculated as the sum of net income for Innovex of approximately $83 million and TCO of approximately $12 million, in each case, for the year ended December 31, 2025, divided by 70,073,038, which is the sum of the basic weighted average number of Innovex’s shares outstanding for the year ended December 31, 2025 of 69,009,209 and the 1,063,829 Consideration Shares. The net income amounts do not give effect to costs, charges, synergies, or other similar items that could result from a combined company.The financial information of TCO Group included in this Current Report on Form 8-K was converted from Norwegian kroner to U.S. dollars at an exchange ratio of 0.1056 representing the closing exchange rate as of June 11, 2026.

Non-GAAP Measures of TCO Group

This Current Report on Form 8-K contains both financial measures prepared and presented in accordance with generally accepted accounting principles (“GAAP”) and non-GAAP financial measures, which are measurements of financial performance that are not prepared and presented in accordance with GAAP. Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow and Transaction ROCE are non-GAAP financial measures of TCO Group. These non-GAAP financial measures should not be construed as being more important than the comparable GAAP measures. The Company’s management uses TCO’s non-GAAP financial measures to evaluate results of operations of TCO Group and believes they provide investors with additional information useful for evaluating the acquisition of TCO Group. These non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation, or as a substitute for analysis of results of operations as reported in accordance with GAAP. In addition, because not all companies use identical calculations, the non-GAAP financial measures included in this Current Report on Form 8-K may not be comparable to similarly titled measures disclosed by other companies.

Adjusted EBITDA is defined as net income or loss before net interest expense or income, income tax expense or benefit, depreciation and amortization and other expense or income, further adjusted to exclude certain items that the Company believes are not reflective of ongoing performance or that are non-cash in nature. Adjusted EBITDA Margin is calculated as Adjusted EBITDA divided by revenue. Free Cash Flow is defined as cash provided by operations less capital expenditures. Transaction ROCE is defined as TCO Group’s 2025 operating income less TCO Group’s 2025 tax expense, divided by the Purchase Price.

Reconciliations of TCO Group’s Adjusted EBITDA to net income, Adjusted EBITDA Margin to net income margin, Free Cash Flow to net cash provided by operating activities, and Transaction ROCE to operating income are set forth below.
