NEW YORK, May 2, 2006 (PRIMEZONE) -- Overseas Shipholding Group, Inc. (NYSE:OSG), a market leader in providing energy transportation services, today reported results for the first fiscal quarter of 2006.

For the quarter ended March 31, 2006, net income was $128.4 million, down 22% from $164.9 million in the same period a year earlier. Diluted earnings per share were $3.24, in comparison with $4.18 per share in the first quarter of 2005. TCE revenues in the quarter increased by 5% to $280.1 million compared with $267.2 million in the first quarter of 2005.

"OSG generated strong results and cash flows in the quarter, clearly demonstrating the advantages of having a large, diverse and modern fleet," stated Morten Arntzen, President and CEO of OSG. "This enabled us to strengthen our balance sheet, increase our book of long-term fixed charter revenue and pursue capital-efficient growth." Arntzen continued, "Looking toward the future, our newbuild program of 24 vessels across all segments provides us with improved scale and efficiencies to compete on a worldwide basis and provide superior service to our customers. This scale is critical to our success."

Quarter-over-quarter, TCE revenues for the crude oil segment were $207.1 million, up 3%, principally due to an increase of revenue days in the VLCC and Panamax sectors partially offset by the 2005 sale and redelivery of two Aframax tankers and off hire days in the period. TCE revenues in the product carrier segment were $53.9 million, up 36%, due to an increase in revenue days and higher average rates earned in both the spot and time charter markets. U.S. segment revenues were down 34% quarter-over-quarter to $13.0 million, as a result of a decrease in revenue days reflecting the sale of three crude tankers in 2005 coupled with an increase in drydock days during the period. The decrease in revenue days was partially offset by an increase in rates.

Of the $280.1 million in TCE revenues, approximately 72% were derived from the spot market and 28% from time and bareboat charters. OSG's fleet diversification strategy and the increase in revenues derived from product carriers, the majority of which trade on medium to long-term charters, has enabled OSG to reduce the percentage of TCE revenues from the spot market from 79% in 2003 and 85% in 2004. Detailed spot and time charter rates by vessel class can be found in Spot and Time Charter TCE Rates Achieved later in this press release.

For the three months ended March 31, 2006, total ship operating expenses increased $41.5 million to $150.6 million. The increase in time and bareboat charter expenses of $17.4 million resulted from the sale and charter back of 13 vessels. Vessel expenses increased $5.1 million principally due to additional costs incurred on three reflagged vessels that participate in the U.S. Maritime Security Program, increased crew costs and the timing of certain purchases, such as spares and stores. General and administrative expenses increased $8.0 million principally due to additional headcount, the recognition of targeted cash incentive compensation on a quarterly basis, expenses incurred in connection with investigations by the U.S. Department of Justice and increases in legal, accounting and consulting services. In addition, lower earnings from asset sales accounted for an increase in quarter-over-quarter ship operating expenses of $13.0 million.

Highlights of Recent Activities and First Quarter Events

Fleet Expansion

-- On March 7, 2006, OSG signed an agreement with a subsidiary of Cido Tanker Holding Co., a privately held shipping company headquartered in Hong Kong, to time charter two International Flag product carriers for a period of seven years, with an additional three year extension option for each vessel. The vessels will be built by Hyundai Mipo Dockyard in South Korea and are scheduled to be delivered to OSG in May and June 2008.

-- On March 29, 2006, OSG announced that it will build four 114,000 dwt 44-meter beam Aframax tankers at the New Times Shipbuilding Co. Ltd. shipyard based in Jinjiang, China. The vessels, scheduled for delivery in 2008 and 2009, will increase OSG's Aframax fleet to 21 tankers serving customers in the Atlantic basin, and will operate in the Aframax International pool. The tankers will be built using the new Common Structural Rules recently established by the International Association of Classification Societies (IACS) for all tankers and bulk carriers ordered after April 1, 2006 which includes stricter hull strength requirements.

-- On April 7, 2006, OSG signed long-term time charter-out agreements for two more of its Jones Act product carriers being built at the Aker Philadelphia Shipyard. The agreement between OSG and Tesoro Maritime Company, an independent refiner and marketer of petroleum products, is in addition to four other previously announced long-term charters: two with Shell Trading U.S. Company, a subsidiary of Shell Oil, and two with British Petroleum PLC. To date, six of the Company's ten newbuild Jones Act Product Carriers have been secured by long-term charters at attractive rates.

-- On April 24, 2006, Flota Petrolera Ecuatoriana (FLOPEC), an Ecuadorian state-owned oil company, joined Panamax International. The addition of five Panamax tankers from FLOPEC's fleet increases the joint venture's fleet to 20 modern, double hull tankers, all of which trade in the Americas.

Fleet Metrics and Statistics

-- As of March 31, 2006, OSG had an operating fleet of 89 International Flag and U.S. Flag vessels. Fifty-six percent, or 50 vessels, were owned, compared with 69%, or 68 vessels, as of March 31, 2005.

-- OSG's newbuild program of chartered-in and owned vessels totals 24 and spans across all lines of business: four International Flag crude tankers; six International Flag product carriers; and 10 Jones Act product carriers, representing 1.2 million deadweight tons, and four LNG carriers, representing 864,800 cubic meters.

-- Revenue days in the quarter totaled 7,208, an increase of 1% over the same period a year earlier.

Other Corporate Activities

-- On April 12, 2006, OSG's Board of Directors announced a quarterly dividend of $0.25 per share, a 43% increase from $0.175 per share, which had been in place since June 2003. OSG has paid a quarterly dividend to shareholders since 1974.

-- On April 3, 2006, OSG announced that Jean-Paul Vettier, a retired senior executive of Total S.A., the fourth largest publicly-traded oil and gas company in the world, had been appointed to its Board of Directors, effective April 1, 2006.

Financial Profile

During the first fiscal quarter, shareholders' equity increased by $135.3 million to more than $2.0 billion and liquidity, including undrawn bank facilities, increased to more than $1.75 billion. Total long-term debt as of March 31, 2006 was $854.5 million compared with $965.7 million at December 31, 2005. Liquidity adjusted debt to capital was 19.5% as of March 31, 2006, an improvement from 24.5% as of December 31, 2005.

On February 15, 2006, the Company announced it had entered into a $1.5 billion seven-year unsecured revolving credit agreement with a group of banks. Borrowings under this facility bear interest at a rate based on LIBOR. The terms, conditions and financial covenants contained therein are generally more favorable than those contained in the Company's prior long-term facilities. In connection with entering into the agreement, the Company terminated all of its other unsecured revolving credit facilities (long-term credit agreements of $1.285 billion and a short-term agreement of $45 million).

Market Overview

Worldwide oil demand during the first quarter of 2006 increased by approximately 700 thousand barrels per day ("b/d"), or 0.9%, compared with the first quarter of 2005. While there was no oil demand growth in OECD countries, non-OECD demand rose by 2.3%. The largest increase in demand of 5.2% occurred in the Middle East and, therefore, had no impact on tanker demand. Oil demand growth stagnated in Southeast Asia as reductions in or eliminations of fuel subsidies had a depressing impact on demand.

Tanker supply increased by 1.3%, or 4.1 million dwt, during the first quarter of 2006 from year-end 2005 levels. While there was growth in all vessel categories, the highest percentage growth was in the Panamax sector, where tonnage increased by 2.4%. Product Carriers, on the other hand, reflected the lowest percentage growth at 1.1%. The additional tonnage exerted downward pressure on TCE rates. Also, since the beginning of 2006, approximately 18 million dwt have been ordered. The high volume of ordering was, in part, a reflection of the April 1, 2006 effective date for the Common Structural Rules ("CSR") that resulted in more stringent shipbuilding requirements and an increase in newbuilding prices for tankers ordered after the effective date.

Vessels ordered today will, for the most part, not be delivered until the end of 2008 for Product Carriers and the end of 2009 for crude tankers. Shipyards are operating at or near full capacity and thus have no incentive to reduce newbuilding prices. Prices for newbuilds remained strong during the first quarter, increasing by 3% to 5% from year-end 2005 levels, depending upon vessel category. In some instances, owners who were willing to pay a premium for immediate delivery paid higher prices for modern second hand vessels than for newbuildings.

Key factors that affected first quarter 2006 rates included a record high U.S. refining maintenance program that significantly reduced refinery utilization rates. This reduced demand for crude oil imports, but resulted in higher U.S. product imports. Warmer than normal temperatures in the U.S. Northeast, however, reduced overall product demand for heating oil in the U.S. At the same time, colder than normal temperatures in Japan increased requirements for crude oil and fuel oil. In addition, supply interruptions in the North Sea, Brazil and the Former Soviet Union ("FSU") reduced available non-OPEC crude oil supplies during the same period that OPEC crude oil supplies were affected by significant disruptions to Nigeria's oil infrastructure, continued problems in Iraq and heightened tensions with Iran. All these factors contributed to changes in supply patterns, which supported tanker rates during the quarter.

 ---------------------------------------------------------------------
 EBITDA represents operating earnings, which is before interest
 expense and income taxes, plus other income and depreciation and
 amortization expense. EBITDA is presented to provide investors with
 meaningful additional information that management uses to monitor
 ongoing operating results and evaluate trends over comparative
 periods. EBITDA should not be considered a substitute for net income
 or cash flow from operating activities prepared in accordance with
 accounting principles generally accepted in the United States or as a
 measure of profitability or liquidity. While EBITDA is frequently
 used as a measure of operating results and performance, it is not
 necessarily comparable to other similarly titled captions of other
 companies due to differences in methods of calculation. The table
 reconciles net income, as reflected in the condensed consolidated
 statements of operations, to EBITDA.
