Helix Reports Fourth Quarter Results and 2008 Outlook

HOUSTON, TX — Helix Energy Solutions (NYSE: HLX) reported fourth quarter net income of $120.4 million, or $1.25 per diluted share. These results included a $151.7 million pre-tax gain ($1.02 per diluted share) related to our majority owned investment in Cal Dive. This non cash gain results from the acquisition by Cal Dive during the fourth quarter of Horizon Offshore using cash and shares of Cal Dive common stock, resulting in an adjustment in our investment in Cal Dive. During the quarter we also recorded oil and gas impairments / dry hole costs totaling $91.0 million and other net non-recurring charges of $3.4 million (see details on slide 7 of attached presentation). These impairments included $20.9 million pre-tax for the write-off of Devil’s Island as a result of drilling a well in Q1 2008 which found no additional hydrocarbons (the additional $13 million cost of drilling the well will be expensed, as required, in Q1 2008). The net result of these unusual items in Q4 2007 is $0.38 per diluted share. Absent these items, net income for the fourth quarter of 2007 was $83.2 million, or $0.87 per diluted share. This compares to $0.71 per share generated in the fourth quarter of 2006 before the $1.02 per share gain realized in that quarter from the carve-out IPO of our Shelf Contracting segment (“Cal Dive”).

Owen Kratz, President and Chief Executive Officer of Helix, stated, “We are very pleased with the strength in our business units and the value creation inherent in the company. Helix personnel continue to handle the growth with continued quality improvements. We look forward to 08 as a settling out year during in which the value that has been created can begin to be unlocked.”

Financial Highlights

• Revenues: The $104 million increase in year-over-year fourth quarter revenues was driven by both Oil and Gas production and Contracting Services increases, due primarily to extra capacity on the shelf (Cal Dive) and continued escalating market demand in the deepwater. The increase in oil and gas revenues was due primarily to a 16% increase in year-over-year production. In addition, on the oil and gas side the sale of a 30% working interest in the Phoenix oilfield last quarter resulted in over $20 million of operating income during the fourth quarter.

• Margins: Absent the oil and gas impairments / dry hole costs, despite the fact that gross profit was higher by $10 million, margins for the fourth quarter 2007 were 32%, which were six points lower than 38% in the fourth quarter of 2006 as Cal Dive experienced a seasonal margin decline, the Q4000 was out of service for upgrades, and a significant project during the quarter utilized a chartered vessel.

• SG&A: $45.2 million increased $4.4 million over the same period a year ago due primarily to increased overhead to support our growth. This level of SG&A was 9% of fourth quarter revenues, compared to 10% in the year ago quarter.

• Equity in Earnings: $10.5 million is comprised of our share of earnings for the quarter relating to the Marco Polo facility and the Independence Hub facility.

• Gain on subsidiary equity transactions: In December, 2007, Cal Dive (CDI) closed its acquisition of Horizon. CDI issued an aggregate of approximately 20.3 million shares of common stock and paid approximately $300 million in cash in the merger. The cash portion of the merger consideration was paid from CDI’s cash on hand and from borrowings under its new $675 million credit facility consisting of a $375 million senior secured term loan and a $300 million senior secured revolving credit facility, each of which is non-recourse to Helix. As a result of CDI’s equity issued, we recorded a $151.7 million pre-tax gain. The gain was calculated as the difference in the value of our investment in CDI immediately before and after CDI’s stock issuance.

• Income Tax Provision: The Company’s effective tax rate for the quarter was 33%, just below the 34% effective rate for last year’s fourth quarter backing out the impact of the Cal Dive IPO.

• Balance Sheet: Total consolidated debt as of December 31, 2007 was $1.8 billion. This includes $375 million outstanding under Cal Dive’s term loan that was used to fund the cash portion of its acquisition of Horizon Offshore and is non-recourse to Helix. Total consolidated debt as of December 31, 2007 represents 49% debt to book capitalization and an adjusted leverage ratio 2.2 times adjusted EBITDAX of $824 million.

• 2008 Outlook: Included in the presentation is information, including estimates with respect to certain key variables, relating to our views on 2008 which we will discuss on the conference call described below.

Ratio		2.2

We calculate adjusted EBITDAX as earnings before net interest expense, taxes, depreciation and amortization, exploration expense, non-cash stock compensation expense and our share of depreciation, net interest expense and taxes from our equity investments. Further, we reduce adjusted EBITDAX for the minority interest in Cal Dive that we do not own. Adjusted EBITDAX margin is defined as adjusted EBITDAX divided by net revenues. 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. 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.
