EXPLANATORY NOTE

Oceaneering International, Inc. (the “Company”) is filing this Amendment No. 1 on Form 10-K/A (this “Form 10-K/A”) to amend its Annual Report on Form 10-K for the fiscal year ended December 31, 2024, as originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 24, 2025 (the “Original Form 10-K”), solely for the purpose of correcting the number of shares of Common Stock outstanding as of February 14, 2025. Accordingly, this Form 10-K/A consists solely of the cover page, this Explanatory Note and the Exhibit Index and the exhibits filed hereto or incorporated by reference herein.

Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended, this Form 10-K/A also contains new certifications by the principal executive officer and the principal financial officer as required by Section 302 of the Sarbanes-Oxley Act of 2002. Accordingly, Item 15(a)(3) of Part IV is amended to include the currently dated certifications as exhibits. Because this Form 10-K/A does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. Additionally, because this Form 10-K/A does not include financial statements, the Company is not including certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002.

Except as expressly noted in this Form 10-K/A, this Form 10-K/A does not reflect events occurring after the original filing of the Original Form 10-K or modify or update in any way any of the other disclosures contained in the Original Form 10-K, including, without limitation, the financial statements or other financial information included therein or the exhibits thereto. Information not affected by this Form 10-K/A remains unchanged and reflects the disclosures made at the time the Original Form 10-K was made. Accordingly, this Form 10-K/A should be read in conjunction with the Original Form 10-K and the Company’s other filings with the SEC.
