CORE LAB ANNOUNCES $60,000,000 “AT-THE-MARKET” EQUITY OFFERING PROGRAM

AMSTERDAM (9 June 2022) — Core Laboratories N.V. (NYSE and Euronext Amsterdam: “CLB”) (“Core,” “Core Lab” or the “Company”) announced today that it has established an “at-the-market” equity offering program (the “ATM Program”) under which it may, from time to time, sell its common shares having an aggregate sales price of up to $60,000,000 (the “Shares”), and has entered into an equity distribution agreement (“Equity Distribution Agreement”) with Wells Fargo Securities, LLC (“Wells Fargo Securities”) and BofA Securities, Inc. (“BofAS”), as sales agents.

Upon delivery of a placement notice and subject to the terms and conditions of the Equity Distribution Agreement, Wells Fargo Securities and BofAS will use reasonable efforts consistent with their normal trading and sales practices, applicable laws and the rules of the New York Stock Exchange to sell the Shares from time to time based upon Core Lab’s instructions for the sales, including price, time or size limits specified by Core Lab. Pursuant to the Equity Distribution Agreement, sales of the Shares may be made by any method permitted by law, including in ordinary brokers’ transactions, negotiated transactions, block trades and transactions deemed to be “at-the-market” offerings, as defined in Rule 415 under the Securities Act of 1933, as amended. Each of Wells Fargo Securities’ and BofAS’ obligations to sell the Shares under the Equity Distribution Agreement are subject to satisfaction of certain conditions, including customary closing conditions.

Core Lab has agreed to reimburse Wells Fargo Securities and BofAS for certain specified expenses and has also agreed to provide Wells Fargo Securities and BofAS with customary indemnification and contribution rights. Core Lab is not obligated to sell any Shares under the Equity Distribution Agreement and may at any time suspend solicitation and offers under the Equity Distribution Agreement. The Equity Distribution Agreement may be terminated with respect to either of Wells Fargo Securities or BofAS by Core Lab at any time by giving written notice to Wells Fargo Securities or BofAS, as applicable, for any reason, or by either of Wells Fargo Securities or BofAS at any time by giving written notice to Core Lab for any reason, or immediately under certain circumstances, including, but not limited to, the occurrence of a material adverse change in the Company. The ATM Program pursuant to the Equity Distribution Agreement will automatically terminate upon the issuance and sale of all of the Shares through Wells Fargo Securities or BofAS.

Core Lab intends to use the net proceeds from the sales of the Shares, if any, for general corporate purposes, which may include, among other things, investments in the development of new products and technology, capital expenditures, repayments of indebtedness, working capital and potential acquisitions. Pending these uses, Core Lab intends to invest the net proceeds in investment-grade interest-bearing obligations, highly liquid cash equivalents, certificates of deposit or direct or guaranteed obligations of the United States of America.

The Shares will be offered under the Company’s existing shelf registration statement on Form S-3ASR (File No.: 333-245691) filed with the Securities and Exchange Commission (the “SEC”). The offering is being made by means of a prospectus supplement to the prospectus contained in the registration statement. Before making an investment in the Shares, potential investors should read the prospectus and the prospectus supplement for more complete information about Core Lab and the offering. Potential investors may obtain these documents for free by visiting EDGAR on the SEC’s website at www.sec.gov.
