Olympic Steel Reports Third-Quarter 2025 Results

Company has entered into a definitive merger agreement with Ryerson

Strong performance from Specialty Metals Segment and manufactured products companies drove third-quarter earnings

Proven track record of acquisitions and organic growth initiatives underscores a stronger, more resilient Company

CLEVELAND — October 28, 2025 — Olympic Steel, Inc. (Nasdaq: ZEUS), a leading national metals service center, today announced financial results for the three months ended September 30, 2025.

Net income for the third quarter totaled $2.2 million, or $0.18 per diluted share, compared with net income of $2.7 million, or $0.23 per diluted share, in the third quarter of 2024. The results include $0.1 million of LIFO expense in the third quarter of 2025 and $2.0 million of LIFO income in the third quarter of 2024. Adjusted EBITDA for the third quarter of 2025 was $15.4 million, compared with $13.0 million in the third quarter of 2024.

The Company reported sales totaling $491 million in the third quarter of 2025, up 4.5% compared with $470 million in the third quarter of 2024.

“Olympic Steel’s third-quarter performance demonstrates the resilience of our business model,” said Richard T. Marabito, Chief Executive Officer. “Despite softer demand caused by trade and interest rate uncertainty, our margins remained solid and we generated $15.4 million of Adjusted EBITDA. All three business segments contributed to profitability, with Specialty Metals performing especially well, with its strongest shipping quarterly volume in the past three years.”

Marabito continued, “Our ability to consistently deliver profitable results amid continued economic uncertainty and recessionary-like conditions for the industrial sector is a testament to the successful execution of our strategy. By diversifying our business, focusing on higher-margin opportunities, maintaining operational discipline and investing to drive efficiency and growth, we have strengthened our competitiveness. Our consolidated year-to-date volumes have outpaced the industry, expanding our market share, and we remain well-positioned and optimistic for the future.”

The Board of Directors approved a regular quarterly cash dividend of $0.16 per share, which is payable on December 15, 2025, to shareholders of record as of December 1, 2025. The Company has paid a regular quarterly dividend since March 2006.

As separately announced, the Company and Ryerson Holding Corporation (“Ryerson”) have entered into a definitive merger agreement pursuant to which the Company will become a wholly owned subsidiary of Ryerson. The transaction is expected to close in the first quarter of 2026, subject to the satisfaction or waiver of customary and other closing conditions, including regulatory and shareholder approvals. Due to this pending transaction, our regularly scheduled earnings call for Friday, October 31, has been canceled.
