CAMERON FIRST QUARTER EARNINGS PER SHARE $0.51, EXCLUDING CHARGES OF $0.03 PER SHARE

·   Quarter’s earnings total $0.48 per share, including charges, versus $0.52, including charges, in first quarter of 2009

·   Backlog declines modestly, totals just below $5 billion at quarter’s end

·   Full-year 2010 guidance raised to $2.20 to $2.30

HOUSTON (April 29, 2010) -- Cameron (NYSE: CAM) reported net income of $120.4 million, or $0.48 per diluted share, for the quarter ended March 31, 2010, compared with net income of $114.6 million, or $0.52 per diluted share, for the first quarter of 2009.  The first quarter 2010 results include pretax charges of $10.3 million, or $0.03 per diluted share, for severance-related costs in certain of the Company’s businesses and acquisition integration costs.  The first quarter 2009 results included a pretax charge of $22.3 million, or $0.07 per diluted share, for severance-related costs.

Year-over-year revenues up slightly

Revenues were $1,346.7 million for the quarter, up seven percent from $1,257.0 million, and income before income taxes was $160.5 million (including the $10.3 million charge), down four percent from $167.3 million (including the $22.3 million charge) a year ago.  Cameron President and Chief Executive Officer Jack B. Moore said that the revenue increase is due primarily to increased subsea project deliveries and the addition of NATCO in Drilling & Production Systems (DPS), which more than offset lower sales in the Valves & Measurement (V&M) and Compression Systems groups.  “The quarter’s earnings reflect the slight year-over-year decline in overall margins that we had expected, and are a result of changes in the revenue mix and the impact of shipments of orders that were booked at lower prices in the softer markets over the past year and a half,” Moore said.  “We continue to expect total margins for the Company to bottom at some time during 2010.”

Orders reflect addition of NATCO, improvement in V&M’s markets

Total orders were $1.21 billion for the quarter, up from $983 million in the first quarter of 2009, reflecting the first full quarter of NATCO’s inclusion in the Process Systems business and modest levels of recovery in certain markets.  “While much of the year-over-year increase is due to the NATCO acquisition,” Moore said, “we saw gains, both sequentially and versus a year ago, in every product line within the V&M group, as they recorded their highest order totals since the third quarter of 2008.”

Cameron’s backlog at the end of the first quarter was $4.98 billion, down modestly from $5.27 billion a year ago and from the December 31, 2009 level of $5.19 billion.  Moore noted that backlog in the Drilling and Subsea businesses came down as project deliveries continued, with those declines partially offset by increases in backlog across all of V&M’s product lines and in the Surface and Process Systems lines within DPS.  “Our backlog at quarter’s end is down only about four percent sequentially,” he said, “reflecting the order strength in certain markets, particularly in V&M.”

Cash generation for year expected to more than cover internal needs

Cameron’s operations utilized cash of $115.8 million during the first quarter of 2010, compared with a cash use of $128.3 million a year ago.  Moore said the cash utilization in the first quarter was not unexpected, and that the Company still anticipates that it will generate ample free cash flow for the full year.  He also noted that capital spending during 2010 is expected to total approximately $180 million, down from $241 million last year.  Moore said the lower capital needs in the current year reflect the completion of investments in new and expanded manufacturing facilities in Romania and Malaysia.

Balance sheet remains strong, share buybacks continue

As of March 31, 2010, Cameron’s $1.62 billion of cash and cash equivalents exceeded its total debt by approximately $356 million.  “Our balance sheet is healthy and we continue to assess opportunities for uses of cash,” Moore said, “including acquisitions and repurchases of our own stock.” He noted that Cameron repurchased approximately one million shares of its common stock during the first quarter at an average price of $42.23 per share.

Earnings guidance adjusted to reflect improved outlook

Moore said that Cameron’s second quarter earnings are expected to be in the range of $0.52 to $0.55 per share, and that the Company anticipates that full-year 2010 earnings will be in the range of $2.20 to $2.30 per share, compared with earlier expectations of $2.10 to $2.20.  He noted that these figures exclude the charges recorded in the first quarter results, as well as any similar charges that may be recognized during the year.  “The increase in our guidance reflects an improved outlook for the Company’s shorter-cycle businesses,” Moore said.  “While we remain cautious about the near-term level of rig activity, particularly in North America, we are encouraged by the strengthening we’ve seen in several of our markets.”

Cameron (NYSE: CAM) is a leading provider of flow equipment products, systems and services to worldwide oil, gas and process industries.
