OVERSEAS SHIPHOLDING GROUP REPORTS

FIRST QUARTER 2024 RESULTS

Tampa, FL – May 10, 2024 – Overseas Shipholding Group, Inc. (NYSE: OSG) (the “Company” or “OSG”), a leading provider of liquid bulk transportation services in the energy industry for crude oil and petroleum products in the U.S. Flag markets, today reported results for the first quarter of 2024.

	●	Net income for the first quarter of 2024 was $14.6 million, or $0.19 per diluted share, compared to net income of $12.1 million, or $0.14 per diluted share, for the first quarter of 2023.

	●	Adjusted EBITDA^(A), a non-GAAP measure, for the first quarter of 2024 was $43.9 million, an increase of $3.0 million, or 7.3%, from the first quarter of 2023.

	●	Shipping revenues for the first quarter of 2024 were $117.5 million, an increase of $3.7 million, or 3.3%, compared to the first quarter of 2023.

	●	Time charter equivalent (TCE) revenues^(B), a non-GAAP measure, for the first quarter of 2024 were $110.1 million, an increase of $6.0 million, or 5.7%, compared to the first quarter of 2023.

	●	Total cash and investments^(c), a non-GAAP measure, were $97.2 million as of March 31, 2024.

	●	On March 14, 2024, the Company’s Board of Directors declared a cash dividend of $0.06 per share on the Company’s Class A common stock, which was paid on April 10, 2024.

	●	In March 2024, the Company exercised its first option to extend the bareboat charter of the Overseas Tampa with its vessel owner for a five-year option period, commencing June 2025 until June 2030.

Sam Norton, OSG’s President and CEO, said, “OSG’s first quarter results continued the recent trend of steadily improving cashflow and profitability. The 35.7% growth in earnings per share when compared with the first quarter of 2023 is particularly noteworthy, reflecting in one data point the combined effect of numerous initiatives undertaken over the past 12 months to deliver shareholder value. In this light, it is also gratifying that the Board expressed its confidence by declaring a second quarterly dividend at the end of March.”

Mr. Norton continued, “Disruptions to historical trading patterns caused by hostilities in the Red Sea, growing geopolitical tensions in the Persian Gulf, and the continuing war in Ukraine have kept international freight markets at or near historical highs. Most analysts consider this market strength to be durable, with positive implications for our Jones Act vessels. High international freight rates indirectly stimulate domestically sourced fuel consumption – and by extension Jones Act transportation demand – since import substitution is constrained by comparatively high freight costs for product shipped over longer distances on foreign flag vessels. So long as international freight rates remain high, “Buy America”, when it comes to fuels, will have economic as well as rhetorical implications.”

Mr. Norton concluded by stating, “We are pleased with the start we have made to meeting our 2024 financial targets and remain confident that the future offers opportunities to sustain and extend our presence in the business sectors served by OSG’s vessels and personnel.”

First Quarter 2024 Results

Shipping revenues were $117.5 million for the first quarter of 2024, an increase of $3.7 million, or 3.3%, compared to the first quarter of 2023. TCE revenues were $110.7 million for the first quarter of 2024, an increase of $6.0 million, or 5.7%, from the first quarter of 2023. The increases primarily resulted from (a) an increase in average daily rates earned by our fleet, (b) an increase in Delaware Bay lightering volumes and (c) a 5-day decrease in repair days. The increase was moderated by a 22-day increase in drydock days.

Operating income for the first quarter of 2024 was $23.5 million compared to operating income of $22.5 million for the first quarter of 2023. Net income for the first quarter of 2024 was $14.6 million, or $0.19 per diluted share, compared with net income of $12.1 million, or $0.14 per diluted share, for the first quarter of 2023.

Adjusted EBITDA was $43.9 million for the first quarter of 2024, an increase of $3.0 million compared with the first quarter of 2023, driven primarily by the increase in TCE revenues.

Reconciliation to Non-GAAP Financial Information

The Company believes that, in addition to conventional measures prepared in accordance with GAAP, the following non-GAAP measures provide investors with additional information that will better enable them to evaluate the Company’s performance. Accordingly, these non-GAAP measures are intended to provide supplemental information, and should not be considered in isolation or as a substitute for measures of performance prepared with GAAP.

(A) Time Charter Equivalent (TCE) Revenues

Consistent with general practice in the shipping industry, the Company uses TCE revenues, which represents shipping revenues less voyage expenses, as a measure to compare revenue generated from a voyage charter to revenue generated from a time charter. TCE revenues, a non-GAAP measure, provides additional meaningful information in conjunction with shipping revenues, the most directly comparable GAAP measure, because it assists Company management in making decisions regarding the deployment and use of its vessels and in evaluating their financial performance. Reconciliation of TCE revenues of the segments to shipping revenues as reported in the consolidated statements of operations follows:

	Three Months Ended March 31,
	2024		2023
Time charter equivalent revenues	$	110,692	$	104,735
Add: Voyage expenses		6,805		9,056
Shipping revenues	$	117,497	$	113,791

Vessel Operating Contribution

Vessel operating contribution, a non-GAAP measure, is TCE revenues minus vessel expenses and charter hire expenses.

	Three Months Ended March 31,
($ in thousands)	2024		2023
Specialized businesses	$	31,269	$	29,561
Jones Act MR tankers		11,324		9,433

Vessel operating contribution		51,836		46,427
Depreciation and amortization		17,994		16,048
General and administrative		10,354		7,843
Operating income	$	23,488	$	22,536

(B) EBITDA and Adjusted EBITDA

EBITDA represents net income before interest expense, income taxes and depreciation and amortization expense. Adjusted EBITDA consists of EBITDA adjusted to exclude amortization classified in charter hire expenses, interest expense classified in charter hire expenses, loss/(gain) on disposal of vessels and other property, including impairments, net, non-cash stock based compensation expense and the impact of other items that we do not consider indicative of our ongoing operating performance. EBITDA and Adjusted EBITDA do not represent, and should not be a substitute for, net income or cash flows from operations as determined in accordance with GAAP. Some of the limitations of EBITDA and Adjusted EBITDA are: (i) EBITDA and Adjusted EBITDA do not reflect our cash expenditures, or future requirements for capital expenditures or contractual commitments; (ii) EBITDA and Adjusted EBITDA do not reflect changes in, or cash requirements for, our working capital needs; and (iii) EBITDA and Adjusted EBITDA do not reflect the interest expense, or the cash requirements necessary to service interest or principal payments, on our debt. While EBITDA and Adjusted EBITDA are frequently used as a measure of operating results and performance, neither of them is necessarily comparable to other similarly titled measures used by other companies due to differences in methods of calculation. The following table reconciles net income as reflected in the consolidated statements of operations, to EBITDA and Adjusted EBITDA.
