Oceaneering Reports Second Quarter 2026 Results

HOUSTON, July 22, 2026 – Oceaneering International, Inc. ("Oceaneering") (NYSE: OII) today reported second quarter 2026 results.

Second Quarter 2026 Results

•As compared to the second quarter of 2025:

◦Revenue increased 10% to $768 million.

◦Operating income increased 11% to $88.2 million.

◦Net income attributable to Oceaneering increased 19% to $65.0 million.

◦Adjusted EBITDA increased 11% to $115 million.

•Cash Generation

◦Cash flow provided by operating activities was $55.2 million.

◦Free cash flow was $32.0 million.

•Balance Sheet and Capital Allocation

◦Quarter-end cash and cash equivalents totaled $629 million, compared to $434 million at the end of the same period last year.

◦Shares repurchased were 263,335 for approximately $10.0 million.

Rod Larson, Oceaneering's President and Chief Executive Officer, commented, "We delivered a strong second quarter, with our consolidated adjusted EBITDA of $115 million exceeding the top end of our guidance. These positive results were driven by overperformance from our Offshore Projects Group (OPG), where favorable project mix and operational execution drove better-than-expected revenue and profitability. More broadly, our results demonstrate continued strength across our portfolio. All of our segments generated increased revenue and operating income, except for Integrity Management and Digital Solutions (IMDS), which was partially impacted by the ongoing Middle East conflict.

"We also made meaningful improvements to our capital structure. During the second quarter, we initiated a series of transactions to refinance our existing debt and to extend and expand our revolving credit facility. Those transactions will be completed during the third quarter, extending our existing debt maturities, increasing available liquidity, and providing us with flexibility to deliver on our strategic initiatives. As a result, we are better positioned to invest in future growth opportunities while maintaining our disciplined approach to capital allocation.

"As we enter the second half of 2026, we continue to see favorable trends in Aerospace and Defense Technologies (ADTech) and supportive conditions in offshore markets. These factors, combined with our backlog and differentiated portfolio, support our outlook for the remainder of the year. Based on our first-half performance and expectations for the balance of the year, we have updated our full-year consolidated adjusted EBITDA guidance range to $400 million to $440 million."

Updated 2026 Guidance

Full-year 2026 consolidated and segment guidance remains the same except as follows:

•Consolidated adjusted EBITDA is expected to be in the range of $400 million to $440 million.

•IMDS operating income is expected to decrease significantly with operating income margin expected to be in the low-single-digit percentage range.

Second Quarter 2026 Segment Results

As compared to the second quarter of 2025:

•Subsea Robotics (SSR) revenue increased to $232 million, operating income increased 3% to $66.3 million, and EBITDA margin remained flat at 35%. These results were attributable to higher ROV revenue per day utilized and increased Survey activity, as the Ocean Intervention II commenced operations. ROV revenue per day utilized increased to $11,894, while ROV fleet utilization decreased slightly to 66% from 67%, with solid activity levels in Europe and Africa largely offsetting lower activity in the U.S. Gulf.

•Manufactured Products operating income increased to $21.9 million and margin expanded to 15% on a 3% increase in revenue. These improvements were driven by increased profitability in the umbilicals business and improved results in mobility solutions. As of June 30, 2026, backlog was $445 million, with additional orders expected in the second half of the year to positively impact backlog. The book-to-bill ratio was 0.88 for the 12-month period ending on June 30, 2026.

•OPG operating income increased to $30.0 million and margin improved to 16% on a 22% increase in revenue. These results benefited from a favorable project mix, including additional international installation and intervention projects.

•IMDS revenue decreased by 6% on lower volume in West Africa, and operating income decreased by $4.5 million. The decrease in operating income was primarily due to lower activity levels and related cost absorption, as well as increased personnel-related costs, in West Africa and the Middle East.

•ADTech revenue increased 22% to $133 million, operating income increased slightly to $16.4 million, and margin declined to 12%, primarily due to program cost mix and timing.

•At the corporate level, Unallocated Expenses were essentially flat at $46.6 million, consistent with expectations.

Third Quarter 2026 Guidance

As compared to the third quarter of 2025:

Consolidated third quarter 2026 revenue is projected to increase and EBITDA is expected to be in the range of $115 million to $125 million.

At the segment level, for the third quarter of 2026:

•SSR revenue and operating income are expected to increase.

•Manufactured Products revenue and operating income are expected to slightly decrease.

•OPG revenue and operating income are expected to increase.

•IMDS revenue is expected to increase and operating income is expected to be relatively flat.

•ADTech revenue and operating income are expected to increase.

•Unallocated Expenses are expected to be in the $50 million range.

Liquidity

During the second quarter, Oceaneering initiated a series of financing transactions designed to address the maturity of its 2028 senior notes. These transactions, which will be completed during the third quarter, included the issuance of $500 million aggregate principal amount of 6.875% senior notes due 2034, the completion of a tender offer for the outstanding 2028 senior notes, and an amendment to the senior secured revolving credit facility. The amendment increased commitments from $215 million to

$345 million and extended the facility's maturity to July 2031. Together, these actions extended Oceaneering's debt maturity profile while preserving substantial liquidity and financial flexibility.

Non-GAAP Financial Measures

Adjusted net income (loss) and earnings (loss) per share; EBITDA and adjusted EBITDA on a consolidated and on a segment basis (as well as EBITDA and adjusted EBITDA margins); and free cash flow are non-GAAP measures that exclude the impacts of certain identified items. Reconciliations to the corresponding GAAP measures are shown in the tables Adjusted Net Income (Loss) and Diluted Earnings (Loss) per Share (EPS), EBITDA and Adjusted EBITDA and Margins, Free Cash Flow, 2026 Consolidated EBITDA Estimates, 2026 Free Cash Flow Estimate, and EBITDA and Adjusted EBITDA and Margins by Segment. These tables are included below under the caption Reconciliations of Non-GAAP to GAAP Financial Information.

Conference Call Details

Oceaneering has scheduled a conference call and webcast on Thursday, July 23, 2026 at 10:00 a.m. Central Time (11:00 a.m. Eastern Time), to discuss its results for the second quarter of 2026 and guidance for the third quarter and full year of 2026. A link to the webcast will be posted on Oceaneering's Investor Relations website. A replay of the conference call will be made available on the website approximately two hours following the conclusion of the live call.

RECONCILIATIONS OF NON-GAAP TO GAAP FINANCIAL INFORMATION

In addition to financial results determined in accordance with U.S. generally accepted accounting principles ("GAAP"), this press release also includes non-GAAP financial measures (as defined under certain rules and regulations promulgated by the Securities and Exchange Commission). We have included adjusted net income (loss) and diluted earnings (loss) per share (EPS), each of which excludes the effects of certain specified items, as set forth in the tables that follow. As a result, these amounts are non-GAAP financial measures. We believe these are useful measures for investors to review because they provide consistent measures of the underlying results of our ongoing business. Furthermore, our management uses these measures as measures of the performance of our operations. We have also included disclosures of earnings before interest, taxes, depreciation, and amortization (EBITDA), EBITDA margins, second quarter of 2026 consolidated adjusted EBITDA, consolidated adjusted EBITDA margins, and free cash flow, third quarter of 2026 consolidated EBITDA estimate, and full year 2026 consolidated EBITDA and free cash flow estimates, as well as the following by segment: EBITDA, EBITDA margins, adjusted EBITDA, and adjusted EBITDA margins. We define EBITDA margin as EBITDA divided by revenue. Adjusted EBITDA and adjusted EBITDA margins and related information by segment exclude the effects of certain specified items, as set forth in the tables that follow. Due to the forward-looking nature of EBITDA for the third quarter of 2026, and for the full year of 2026, we cannot reliably predict certain of the necessary line items for the reconciliations to net income and, accordingly, have excluded such line items in the reconciliation. EBITDA and EBITDA margins, adjusted EBITDA and adjusted EBITDA margins, and related information by segment are each non-GAAP financial measures. We define free cash flow as cash flow provided by operating activities less organic capital expenditures (i.e., purchases of property and equipment other than those in business acquisitions). We have included these disclosures in this press release because EBITDA, EBITDA margins, and free cash flow are widely used by investors for valuation purposes and for comparing our financial performance with the performance of other companies in our industry, and the adjusted amounts thereof provide more consistent measures than the unadjusted amounts. Furthermore, our management uses these measures for purposes of evaluating our financial performance. Our presentation of EBITDA, EBITDA margins, and free cash flow (and the adjusted amounts thereof) may not be comparable to similarly titled measures that other companies report. Non-GAAP financial measures should be viewed in addition to and not as substitutes for our reported operating results, cash flows, or any other measure prepared and reported in accordance with GAAP. The tables that follow provide reconciliations of the non-GAAP measures used in this press release to the most directly comparable GAAP measures.
