Superior Offshore International Reports
Second Quarter 2007 Preliminary Results

Provides Full-Year Revenue Guidance

HOUSTON — August 14, 2007 — Superior Offshore International, Inc. (NASDAQ: DEEP), a leading provider of subsea construction and commercial diving services to the oil and gas industry, today reported preliminary results for the second quarter and six months ended June 30, 2007.

     Superior Offshore reported total revenues of $41.9 million for the second quarter of 2007, compared with revenues of $60.6 million in the prior year’s second quarter. The Company reported a net loss of $10.8 million, or $0.50 per share, in the second quarter of 2007, compared with net income of $12.1 million, or $0.82 per diluted share, in the second quarter of 2006.

     EBITDA (earnings before interest, income taxes and depreciation and amortization), which is a non-GAAP financial measure, was a negative $11.7 million in the second quarter of 2007, compared with a positive $19.5 million in the second quarter of 2006. A reconciliation of EBITDA with the Company’s net income (loss) and net cash provided by operating activities is found at the end of this news release.

     Second quarter 2007 revenues were impacted by the continued dry-docking and significant upgrades to the Company’s dynamically positioned (DP)Superior Endeavouras previously disclosed in the Company’s first quarter 10-Q. TheEndeavouris currently projected to return to service by the end of August. Four-point surface diving vessel utilization and dayrates were significantly lower in the second quarter of 2007 as compared to the second quarter of 2006 because of decreased demand in the Gulf of Mexico.

     Net results for the latest quarter included a $3.9 million pretax charge, or $0.18 per share, for the early extinguishment of debt. Compared with the year-ago quarter, net results were also impacted by expenses related to the Company’s initial public offering, the relocation of its corporate headquarters to Houston and various costs related to being a public company, including Sarbanes-Oxley compliance and stock-based compensation expenses.

     In the third quarter of 2007, the Company has placed into service theGulmar Condor,chartered two additional DP II vessels in response to increased demand for deep water vessels and placed into service one anchored subsea construction barge. TheSeamec III,theGulmar Condorand theCrossmar 14have been deployed in Trinidad.

     “Over the past few months, we have been transforming Superior Offshore from a shallow water Gulf of Mexico contractor into an international and deepwater subsea construction and services company,” said James J. Mermis, Superior Offshore’s president and chief executive officer. “While second quarter results were clearly disappointing, these changes have created strong opportunities for revenue and margin growth.

     “We expect a strong finish to 2007, based on our current book of business, approximately two-thirds of which is international and deepwater work and non-hurricane related,” said Mermis. “We now have the largest backlog of work the Company has ever had, which solidifies our commitment to international and deepwater work outside the U.S. Gulf of Mexico.

     “In Trinidad, where we began working in June under the largest contract in our history, the customer is contracting theSeamec III,theGulmar Condorand theCrossmar 14. TheGulmar Falconis scheduled to return to work in September, and our client in Trinidad has taken a first right of refusal on her. Given the scope of work on these Trinidad projects and interest expressed from other E&P companies in Trinidad, we expect to establish a permanent presence in the region to serve ongoing demand,” Mermis said.

     “We are also in the process of establishing an office in the United Arab Emirates and a subsidiary in Qatar. We are also focusing on business development in West Africa and the Middle East to leverage our existing client relationships as well as our South African-based subsidiary’s marketing and operational platform in these highly opportunistic areas.”

Year-to-Date Results

     For the six months ended June 30, 2007, Superior Offshore International reported a loss of $4.6 million, or $0.25 per share, on revenues of $96.2 million. First half 2007 results also were impacted by the $0.21 per share charge for early extinguishment of debt. This compares with net income of $24.0 million, or $1.62 per diluted share, on revenues of $110.0 million for the first six months of 2006.

• TheSuperior Endeavour,a DP II vessel,is expected to return to service by the end of August and will immediately go to work in the Gulf of Mexico.

• TheGulmar Condor, a DP II vessel, is presently in Trinidad on hire, with installation of a saturation diving system and work class remotely operated vehicle (ROV) in progress.

• TheSeamec III,a DP II vessel, is on hire in Trinidad.

• TheAdams Surveyor,a DP II vessel, is currently on hire providing deepwater ROV services in the Gulf of Mexico.

• TheGulmar Falcon, a DP II vessel, is in dry dock but is expected to return to service in early September. She is on a right of first refusal to work in Trinidad.

• TheToisa Puma,a DP II vessel, is expected to go to work performing ROV support in the Gulf of Mexico following acceptance of delivery by Superior.

• TheCrossmar 14, an anchored subsea construction barge, is currently on hire in Trinidad.

• TheGulf Diver III, VandVIfour-point surface diving vessels, are allocated to working in the Gulf of Mexico.

2007 Revenue Outlook

     Based on our current estimates, the timing of project work and current market conditions, we project that full-year 2007 revenue will range between $265 million and $285 million. These projections constitute forward-looking statements and are subject to substantial risks and uncertainties. Actual future results could differ materially from these projections as a result of a number of factors, including, but not limited to, possible shipyard delays, project delays and adverse weather conditions in the Gulf of Mexico as well as the other factors described in the prospectus for our initial public offering.

Update on Form 10-Q filing for the period ended June 30, 2007

     In late July 2007, the Company determined that it was the tax withholding agent for a vessel owned by a foreign corporation operated in U.S. waters in 2004 and 2005. The charter agreement stipulates that the vessel owner is responsible for payment of taxes. The Company is required by law to withhold taxes with respect to payments made to the vessel owner, which should have been done as payments were made in 2004 and 2005. The amount that should have been withheld, including interest, is approximately $980,000, which the Company will attempt to collect from the owner of the vessel.

3

Because collection of this amount cannot be assured, the Company has recorded the total amount in cost of revenues in the second quarter of 2007 as reflected in this news release. Our external auditors are reviewing this matter and have not been able to complete their analysis, but expect to do so in the near future. Accordingly, the Company will file a Form 12b-25 to automatically extend the deadline for timely filing of its Form 10-Q to August 20, 2007.

NYMEX crude oil prices (5)	$	66.20		$	73.29		$	73.74		$	64.70		$	61.87		$	68.72

(1)	The number of vessels as of the end of each period represents our DP and four-point vessels owned or under long-term charter. Vessels acquired are treated as added to our fleet as of the date we purchased the vessel. Vessels under long-term charter are treated as part of our fleet during the term of the charter. We define long-term charters as charters of six months or longer. Our method of computation of number of vessels may or may not be comparable to other similarly titled measures of other companies. The number of vessels for the first and second quarters of 2006 includes our ownership of theGulf Diver IVand theGulf Diver VI, which were owned but not in service during those periods. The number of vessels for the third and fourth quarters of 2006 includes our ownership of theGulf Diver IV, which was owned but not in service during those periods, and our charter of theAmerican Salvor, which was under long-term charter but not in service during those periods. The number of vessels for the fourth quarter of 2006 and the first and second quarters of 2007 also includes our charter of theGulmar Condor, which was under long-term charter but not in service during those periods. The number of vessels for the second quarter of 2007 also includes our ownership of theSuperior Endeavour, which was owned but not in service during that period.
(2)	The number of vessel revenue days is the total number of days the vessels generated revenue. Our method of computation of number of vessel revenue days may or may not be comparable to other similarly titled measures of other companies.
(3)	Average vessel utilization is calculated by dividing the total number of days our owned or long-term chartered vessels generated revenues by the total number of days the vessels were available for service in each period and does not reflect days during the period between the dates vessels were acquired and initially placed in service and days vessels were in drydock for regulatory-related inspections and maintenance. Our method of computation of vessel utilization may or may not be comparable to other similarly titled measures of other companies.
(4)	Quarterly average of the Henry Hub natural gas 12-month strip futures price (dollars per Mmbtu).
(5)	Quarterly average of NYMEX WTI crude oil 12-month strip futures price (dollars per barrel).

Non-GAAP Financial Measures

     The body of accounting principles generally accepted in the United States is commonly referred to as “GAAP.” A non-GAAP financial measure is generally defined by the SEC as one that purports to measure historical or future financial performance, financial position or cash flows, but excludes or includes amounts that would not be so adjusted in the most comparable GAAP measures. In this Quarterly Report on Form 10-Q, we disclose EBITDA, a non-GAAP financial measure. EBITDA is calculated as net income (loss) before interest expense (income), provision for income taxes and depreciation and amortization.

     EBITDA is included in this Quarterly Report on Form 10-Q because our management considers it an important supplemental measure of our performance and believes that it is frequently used by securities analysts, investors and other interested persons in the evaluation of companies in our industry, some of which present EBITDA when reporting their results. We regularly evaluate our performance as compared to other companies in our industry that have different financing and capital structures and/or tax rates by using EBITDA. In addition, we utilize EBITDA in evaluating acquisition opportunities. Management also believes that EBITDA is a useful tool for measuring our ability to meet our future debt service, capital expenditures and working capital requirements, and EBITDA is commonly used by us and our investors to measure our ability to service indebtedness.

     EBITDA is not a substitute for the GAAP measures of net income (loss) or cash flow and is not necessarily a measure of our ability to fund our cash needs. In addition, it should be noted that companies calculate EBITDA differently and, therefore, EBITDA as presented for us may not be comparable to EBITDA reported by other companies. EBITDA has

8

material limitations as a performance measure because it excludes interest expense, provision for income taxes and depreciation and amortization.

     EBITDA for the three months ended June 30, 2007 and 2006 was approximately $(11.7) million and $19.5 million, respectively, and EBITDA for the six months ended June 30, 2007 and 2006 was approximately $(1.5) million and $38.9 million, respectively. The following table reconciles EBITDA with our net income (loss) and with our net cash provided by operating activities.
