Purchase Price of $8.50 per Share in Cash

Transaction Valued at $950 Million

Overseas Shipholding Group, Inc. (“OSG” or the “Company”) (NYSE: OSG), a leading provider of liquid bulk transportation services in the energy industry for crude oil and petroleum products primarily in the U.S. Flag markets, and Saltchuk Resources, Inc. (“Saltchuk”), a privately owned family of diversified freight transportation, marine service, and energy distribution companies, today announced that they have entered into a definitive merger agreement pursuant to which Saltchuk has agreed to acquire OSG in a transaction that values the Company at an aggregate equity value of approximately $653 million and a total transaction value of $950 million.

Under the terms of the agreement, which has been unanimously approved by the Board of Directors of both companies, Saltchuk will commence a tender offer to acquire all outstanding shares of OSG it does not already own for $8.50 per share in cash. The purchase price represents a 61% premium to OSG’s 30-day volume-weighted average price on January 26, 2024, the last day of trading before Saltchuk disclosed its non-binding indication of interest, as well as a 44% premium to the January 26 closing price of OSG’s shares and a 36% premium to Saltchuk’s initial indicative price of $6.25 per share.

“We are pleased to have reached an agreement that reflects our leading Jones Act business, longstanding customer relationships, and the value created by the OSG team over the past several years,” said Douglas D. Wheat, Chairman of the OSG Board of Directors. “Following Saltchuk’s indication of interest to buy the Company at the end of January, the Board of Directors, with the assistance of external financial and legal advisors, undertook a review of the Company’s financial and strategic alternatives, including remaining a publicly held company. As part of that review, the Board conducted a comprehensive process in which it engaged with Saltchuk and approached and engaged with other potential transaction counterparties. Informed by its review and that process, the Board firmly believes Saltchuk’s increased offer represents compelling value to, and is in the best interest of, our shareholders not affiliated with Saltchuk.”

“We are excited to enter into this new chapter together with Saltchuk, which has been a significant shareholder of OSG over the past several years and has a close understanding of our business,” said Sam Norton, OSG’s President and Chief Executive Officer. “Saltchuk’s operating companies have distinguished themselves in their respective segments, and this transaction partners us with an organization that shares our values and focus on customers. We are thrilled to soon join the Saltchuk family of companies.”

Mark Tabbutt, Chairman of Saltchuk Resources, said: “OSG, our nation’s leading domestic marine transporter of energy, has a strong cultural fit with Saltchuk and shares our commitment to operational safety, reliability, and environmental stewardship. On behalf of the Saltchuk organization, we look forward to welcoming more than 1,000 members of the OSG team to our family of companies and growing the enterprise through multi-generational investments.”

Following the close of the transaction, OSG will operate as a standalone business unit within Saltchuk, becoming a member of its family of diversified freight transportation, marine service, and energy distribution companies.

The closing of the tender offer will be subject to customary closing conditions, including the expiration of the Hart-Scott-Rodino Act waiting period and the tender of shares representing, together with the shares already owned by Saltchuk, at least a majority of OSG’s outstanding shares of Class A common stock, and is expected to close in the next few months. Promptly following the successful completion of the tender offer, Saltchuk will acquire all remaining OSG shares not purchased in the tender offer through a second-step merger at the same price.

The transaction is not subject to a financing condition. It will be funded through a combination of committed debt financing and cash on hand.
