Helix Reports Quarter 3 Results and Updates 2008 Outlook

HOUSTON, TX — Helix Energy Solutions (NYSE: HLX) reported third quarter net income of $60.6 million, or $0.65 per diluted share. This compares to net income of $82.8 million, or $0.88 per diluted share, reported for the third quarter of 2007, and net income of $90.9 million, or $0.96 per diluted share, in the second quarter of 2008. Net income for the nine months ended September 30, 2008 was $225.8 million, or $2.40 per diluted share, compared to $196.4 million, or $2.07 per diluted share, for the nine months ended September 30, 2007. Net income for the third quarter of 2008 was negatively impacted by shut in oil and gas production resulting from both Hurricanes Gustav and Ike. Third quarter oil and gas production amounted to 10.5 bcfe, which was 4.4 bcfe lower than production for the second quarter of 2008. In addition to the decline in oil and gas production related to the hurricanes, the Company recorded an impairment charge of $6.7 million pre-tax related to oil and gas production in the Tiger field that will be abandoned as a result of damage caused by Hurricane Ike.

The Company realized pre-tax gains on asset sales of oil and gas properties of approximately $19 million in the second quarter of 2008 and $80 million in the nine months ending September 30, 2008. Excluding the impact of these gains, earnings per share for the second quarter of 2008 and nine months ending September 30, 2008 would have been $0.86* and $1.88*, respectively. Likewise, net income for the third quarter of 2007 reflected a pre-tax gain from the sale of a 30% interest in the Phoenix oil and gas field of $19 million, or $0.13 of earnings per share.

Owen Kratz, President and Chief Executive Officer of Helix, stated, “During the third quarter, we achieved record quarterly revenues and gross profit, led by strong performance from both our Contracting Services segment as well as our Shelf Contracting Services segment (Cal Dive), which offset the deferred production resulting from the back-to-back disruptions caused by Hurricanes Gustav and Ike. However, these strong operating results did not translate into a corresponding record for earnings per share due to higher minority interest elimination resulting from Cal Dive’s strong performance and the fact that we did not realize any gains for oil and gas property sales, as we had in the first two quarters of 2008.

Our near term efforts are focused on restoring our oil and gas production, managing our balance sheet as well as our ongoing capital projects.”

(1) Q3, 2007 included a pre-tax gain on the sale of a 30% working interest in the Phoenix field of $19 million. Q2, 2008 included a pre-tax gain of $19 million on sales of oil and gas properties.

Contracting Services

• Deepwater construction revenues in the third quarter of 2008 benefitted from high asset utilization compared to prior periods, combined with high utilization of our robotics assets.

• Revenues from well intervention operations increased in the third quarter as compared to the second quarter of 2008 due mainly to having the Q4000 available for a full quarter at high utilization levels after completing its capital upgrades near the end of the second quarter.

• Gross profit margins for the Company’s Contracting Services segment improved from the second quarter mainly as a result of higher asset utilization.

Shelf Contracting

• Shelf Contracting (Cal Dive) revenues, gross profit and net income increased significantly compared to the second quarter of 2008 as a result of seasonal improvement in demand for its vessels and higher vessel utilization.

• Higher demand rates for Cal Dive’s vessels are allowing the Shelf Contracting segment to realize higher contracting rates, particularly for its surface diving vessels.

Oil and Gas

• Oil and Gas revenues for the three months ended September 30, 2008 decreased significantly compared to the second quarter of 2008 primarily as a result of production shut in from Hurricanes Gustav and Ike. Production for the third quarter of 2008 fell to 10.5 bcfe compared to 14.9 bcfe for the second quarter of 2008.

• As disclosed in the Company’s press release of September 23, 2008, nearly all the Company’s oil and gas production was shut in as a result of Hurricane Ike. As of Monday, October 27, production had been restored to a level of approximately 30% of pre-Hurricane Ike levels of approximately 160 mmcfe/day. Further, the Company’s ability to restore production is subject, for the most part, to the repair and restoration of third party pipelines and onshore production facilities, a matter largely out of the Company’s control. Based on present estimates of when these pipelines and assets will become operational again, the Company anticipates reaching pre-Hurricane Ike production levels by the end of December. Based on these estimates, the Company expects fourth quarter, 2008 production to be in the range of 7.5 to 8.0 bcfe with production in the first quarter of 2009 expected to surpass second quarter, 2008 levels as a result of incremental production anticipated from the Noonan gas discovery. Again, these forecasted production rates are subject to estimated dates for the operational restoration of third party pipelines and onshore processing facilities, a matter largely beyond the Company’s control.

Other Expenses

• Selling, general and administrative expenses for the quarter were 8.2% of revenue, compared to 8.1% in the second quarter of 2008.

• Net interest expense and other increased to $23.5 million in the third quarter of 2008, up from $18.7 million in the second quarter. The increase in other expense was primarily due to higher foreign exchange losses recorded during the quarter as a result of the strengthening of the U.S. dollar.

Financial Condition and Liquidity

• Consolidated net debt at September 30, 2008 increased to $1.87 billion from $1.84 billion as of June 30, 2008. $335 million of total indebtedness relates to Cal Dive’s borrowings under its senior credit facilities, which are non-recourse to Helix. Net debt to book capitalization as of September 30, 2008 was 47%. (Net debt to book capitalization is a non-GAAP measure. See reconciliation attached hereto.)

• As of September 30, 2008, the Company had borrowings and L/Cs outstanding under its revolving credit facility totaling $198.5 million, with $221.5 million available to be drawn under the facility. In order to ensure adequate and readily available liquidity, the Company drew $175 million under the facility during the month of October. The Company expects to utilize a portion of this additional drawdown during the fourth quarter in order to fund its ongoing capital program as well as to fund operations in light of reduced oil and gas production levels.

• Year-to-date capital expenditures (excluding $71 million related to Cal Dive) through September 30, 2008 totaled $658 million. Helix’s projected capital expenditures for 2008 (excluding Cal Dive) will range from $800 to $850 million.

• In light of the impacts to the Company from decreased oil and gas revenues due to hurricane related shut in, the Company has taken the following actions to bolster its financial condition and liquidity:

• Hedged an additional amount of expected 2009 oil and gas production (see quarterly conference call presentation for more details) in order to protect more of the Company’s expected 2009 cash flow.

• Reduced the planned level of 2008 capital expenditures. The previously disclosed range of $800 to $850 million is lower than the $875 to $925 million range previously forecasted after the second quarter of 2008. We have also reduced planned capital spending for 2009 and now expect 2009 capital spending to be approximately half of 2008 levels.

• Drew down the previously mentioned $175 million on its revolving credit facilities. Based on the Company’s current financial projections, assumptions on commodity prices and expected restoration levels of oil and gas production, the Company expects that the remaining capacity in its revolving credit facility will be sufficient to fund operations and capital spending without having to seek additional financial capital.

Further details are provided in the presentation for Helix’s quarterly conference call (see the Investor Relations page of www.HelixESG.com).

Helix Energy Solutions, headquartered in Houston, Texas, is an international offshore energy company that provides reservoir development solutions and other contracting services to the energy market as well as to its own oil and gas business unit. Helix’s contracting services segment utilizes its vessels and offshore equipment that when applied with its methodologies reduce finding and development costs and cover the complete lifecycle of an offshore oil and gas field. Helix’s oil and gas segment engages in prospect generation, exploration, development and production activities. Helix operates primarily in the Gulf of Mexico, North Sea, Asia Pacific and Middle East Regions.

Management evaluates Company performance and financial condition using certain non-GAAP metrics, primarily Adjusted EBITDAX, net debt and net debt to book capitalization. We calculate Adjusted EBITDAX as earnings before net interest expense, taxes, depreciation and amortization and exploration expense. Further, we reduce Adjusted EBITDAX for the minority interest in Cal Dive that we do not own. These non-GAAP measures are useful to investors and other internal and external users of our financial statements in evaluating our operating performance because they are widely used by investors in our industry to measure a company’s operating performance without regard to items which can vary substantially from company to company, and help investors meaningfully compare our results from period to period. Adjusted EBITDAX should not be considered in isolation or as a substitute for, but instead is supplemental to, income from operations, net income or other income data prepared in accordance with GAAP. Net debt is calculated as the sum of financial debt less cash on hand. Net debt to book capitalization is calculated by dividing net debt by the sum of net debt, preferred stock and shareholders’ equity. Non-GAAP financial measures should be viewed in addition to, and not as an alternative to our reported results prepared in accordance with GAAP. Users of this financial information should consider the types of events and transactions which are excluded.
