Rod Larson, Oceaneering's President and Chief Executive Officer, stated, "I am pleased to report another strong quarter, in which we delivered the considerable quarterly year-over-year increases noted above. We achieved these results through commencement of recent contract awards in Aerospace and Defense Technologies (ADTech), favorable service mix and strong execution in our Offshore Projects Group (OPG), conversion of higher margin backlog in Manufactured Products, and continued progression of remotely operated vehicle (ROV) day rates. As expected, all of our operating segments produced quarterly year-over-year improvements in revenue, operating income, and operating income margin."

•Subsea Robotics (SSR) operating income improved 4% to $64.5 million on a 2% increase in revenue. EBITDA margin expanded slightly to 35% on improved ROV revenue per day utilized, which increased to $11,265. ROV fleet utilization was 67%.

•Manufactured Products operating income of $18.8 million improved 31% on a 4% increase in revenue, with operating income margin expanding to 13%. Backlog was $516 million on June 30, 2025. The book-to-bill ratio was 0.65 for the 12-month period ending on June 30, 2025.

•ADTech operating income of $16.3 million represented an increase of 125% on a 13% increase in revenue. Operating income margin expanded to 15%.

•At the corporate level, Unallocated Expenses were $46.7 million.

As compared to the third quarter of 2024, consolidated third quarter 2025 revenue is expected to increase and consolidated EBITDA is forecasted to be in the range of $100 million to $110 million.

•Consolidated revenue is expected to grow in the mid-single digit percent range;

•Consolidated adjusted EBITDA is expected to be in the range of $390 million to $420 million;

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, 2024 consolidated adjusted EBITDA and free cash flow, and 2025 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 2025 and for the full year of 2025, 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.
