***Record full year revenue of $888.3 million***

***Full year net income of $73.5 million (Adjusted net income of $81.6 million)***

***Record full year Adjusted EBITDA of $171.3 million***

HOUSTON, Feb. 23, 2026 (GLOBE NEWSWIRE) -- Great Lakes Dredge & Dock Corporation ("Great Lakes" or the "Company") (Nasdaq: GLDD), the largest provider of dredging services in the United States, today reported financial results for the fourth quarter and year ended December 31, 2025 and the signing of two international offshore energy contracts.

**<u>Fourth Quarter 2025 Highlights</u>**

* Revenue was $256.5 million

* Total operating income was $32.6 million

* Net income was $12.6 million

* Adjusted net income was $20.7 million

* Adjusted EBITDA was $44.0 million 

**<u>Full Year 2025 Highlights</u>**

* Net income was $73.5 million

* Adjusted net income was $81.6 million

* Adjusted EBITDA was $171.3 million

* Backlog as of December 31, 2025 was $888.1 million

**<u>Previously Announced Saltchuk Transaction</u>**

On February 11, 2026, Great Lakes announced that it had entered into a definitive agreement for Saltchuk Resources, Inc. ("Saltchuk") to acquire the Company. The closing of the transaction will be subject to customary closing conditions, including the expiration of the Hart-Scott-Rodino Act waiting period and the tender of shares representing at least one share more than a majority of Great Lakes' outstanding shares of common stock, and is expected to close in Q2 2026.

**<u>Offshore Energy</u>**

Great Lakes entered into two new international offshore energy contracts with a major offshore wind developer. The awarded work will keep the *Acadia* utilized in Europe for the majority of 2027.

**<u>Operational Update</u>**

*Fourth Quarter 2025*

* Revenue was $256.5 million, an increase of $53.7 million from the fourth quarter of 2024. The higher revenue in the fourth quarter of 2025 was due primarily to the first full quarter of the *Amelia Island* working and higher capital and offshore energy revenue as compared to the same period in the fourth quarter last year*,* partially offset by lower coastal protection and maintenance project revenue.

* Gross profit of $53.6 million increased from the fourth quarter of 2024 gross profit of $48.9 million primarily due to improved project performance. Gross profit margin decreased to 20.9% from 24.1% in the fourth quarter of 2024 primarily due to increased drydocking expenses.

* Operating income was $32.6 million, increasing from $30.0 million in the prior year's fourth quarter primarily due to the improved gross profit partially offset by higher general and administrative expenses primarily due to increased incentive compensation and expenses related to the Saltchuk transaction.

* Net income was $12.6 million, decreasing from net income of $19.7 million in the prior year fourth quarter. The decrease was primarily driven by an $8.1 million one-time expense, net of tax impact, from the extinguishment of our second lien notes. Excluding this one-time expense, adjusted net income was $20.7 million.

*Full Year 2025*

* Revenue was $888.3 million, an increase of $125.6 million from 2024. The higher revenue in 2025 was due primarily to the delivery of the *Amelia Island* and higher capital, coastal protection, and offshore energy revenues, partially offset by decrease in maintenance revenue.

* Gross profit and gross profit margin of $203.5 million and 22.9%, respectively, increased from full year 2024 gross profit and gross profit margin of $160.6 million and 21.1%, respectively. The increases were driven by higher revenues as well as improved utilization and project performance in the current year.

* Operating income for the full year 2025 was $127.8 million, which is a $35.0 million improvement from the prior year. The year-over-year increase is primarily a result of higher gross profit in the current year when compared to prior year, partially offset by higher general and administrative expenses primarily due to increased incentive pay in the current year when compared to prior year.

* Net income for the full year 2025 was $73.5 million, which is a $16.2 million improvement compared to $57.3 million for the full year 2024. This increase is primarily driven by improvements to operating income in the current year when compared to prior year, partially offset by an increase in the income tax provision in the current year when compared to prior year as well as by the $8.1 million one-time expense, net of tax impact, from the extinguishment of our second lien notes. Excluding this one-time expense, adjusted net income was $81.6 million.

**<u>Balance Sheet, Backlog & Capital Expenditures</u>**

* At December 31, 2025, the Company had $13.4 million in cash and cash equivalents, total long-term debt of $378.2 million and liquidity of over $330 million.

* At December 31, 2025, the Company had $763.2 million in dredging backlog compared to $1.2 billion at December 31, 2024. Dredging backlog as of December 31, 2025 does not include approximately $200.2 million of awards and options pending.

* At December 31, 2025, the Company had $124.8 million in offshore energy backlog compared to $44.9 million at December 31, 2024. Offshore energy backlog does not include approximately $2.9 million of options pending.

* Total capital expenditures for the full year 2025 were $143.9 million including $69.1 million for the construction of the *Acadia,* $32.3 million for the *Amelia Island,* $13.7 million for support equipment, and $28.8 million for maintenance and growth.

**<u>Conference Call Information</u>**

As previously communicated, in light of the pending transaction with Saltchuk, Great Lakes will not host a conference call and webcast in conjunction with the quarter and year-end report.

**<u>Use of Non-GAAP Measures</u>**

Adjusted EBITDA, as provided herein, represents net income from continuing operations, adjusted for net interest expense, income taxes, depreciation and amortization expense, debt extinguishments, accelerated maintenance expense for new international deployments, goodwill or asset impairments and gains on bargain purchase acquisitions. Adjusted EBITDA is not a measure derived in accordance with GAAP. The Company presents Adjusted EBITDA as an additional measure by which to evaluate the Company's operating trends. The Company believes that Adjusted EBITDA is a measure frequently used to evaluate the performance of companies with substantial leverage and that the Company's primary stakeholders (i.e., its stockholders, bondholders and banks) use Adjusted EBITDA to evaluate the Company's period to period performance. Additionally, management believes that Adjusted EBITDA provides a transparent measure of the Company's recurring operating performance and allows management to readily view operating trends, perform analytical comparisons and identify strategies to improve operating performance. For this reason, the Company uses a measure based upon Adjusted EBITDA to assess performance for purposes of determining compensation under the Company's incentive plan. Adjusted EBITDA should not be considered an alternative to, or more meaningful than, amounts determined in accordance with GAAP including: (a) net income as an indicator of operating performance or (b) cash flows from operations as a measure of liquidity. As such, the Company's use of Adjusted EBITDA, instead of a GAAP measure, has limitations as an analytical tool, including the inability to determine profitability or liquidity due to the exclusion of accelerated maintenance expense for new international deployments, goodwill or asset impairments, gains on bargain purchase acquisitions, net interest expense and income tax expense and the associated significant cash requirements and the exclusion of depreciation and amortization, which represent significant and unavoidable operating costs given the level of indebtedness and capital expenditures needed to maintain the Company's business. For these reasons, the Company uses net income to measure the Company's operating performance and uses Adjusted EBITDA only as a supplement. Adjusted EBITDA is reconciled to net income in the table of financial results. For further explanation, please refer to the Company's Securities and Exchange Commission ("SEC") filings.

Adjusted net income and adjusted diluted earnings per share, as provided herein, represent net income and diluted earnings per share, adjusted for loss on extinguishment of debt. We believe adjusted net income and adjusted diluted earnings per share provide useful information about the Company's operating performance. We believe excluding the [non-recurring loss on extinguishment of debt] provides investors with an alternative and supplemental understanding of our core business. Adjusted net income and adjusted diluted earnings per share are reconciled to net income and diluted earnings per share in the table of financial results. For further explanation, please refer to the Company's SEC filings.
