CIRCOR Announces First Quarter Earnings of $0.76 per share

• Earnings for quarter increase 74% on revenue growth of 9.5%

• Orders and ending backlog each climb 27% and 45% respectively, with strength in both segments compared to the first quarter 2007

Burlington, MA, April 30, 2008

CIRCOR International, Inc. (NYSE: CIR), a leading provider of valves and other fluid control devices for the instrumentation, aerospace, thermal fluid and energy markets, today announced results for the first quarter ended March 30, 2008.

Revenues for the 2008 first quarter were $176.6 million, an increase of 9.5% from $161.3 million for the first quarter 2007. Net income for the first quarter 2008 increased 74% to $12.9 million, or $0.76 per diluted share, compared to $7.4 million, or $0.45 per diluted share, for the 2007 first quarter.

The Company received orders totaling $237.0 million during the first quarter 2008, an increase of 27% over $186.8 million in orders in the first quarter of 2007 due to strength in naval, aerospace and energy markets, including both projects and distribution products, and a sequential increase of 39% over the fourth quarter of 2007. Backlog at March-end 2008 reached another record of $452.0 million, up 45% over March-end 2007 backlog of $311.2 million, and sequentially increasing 15% over the fourth quarter of 2007.

During the first quarter of 2008, the Company used $5.4 million of free cash flow (defined as net cash from operating activities, less capital expenditures and dividends paid) due to investment in working capital to support its record backlog as of March 30, 2008.

Circor’s Instrumentation and Thermal Fluid Controls Products segment revenues increased 9%, to $88.5 million from $81.3 million in the first quarter 2007, with 4% of the increase due to favorable currency adjustments. Incoming orders for this segment were $111.2 million for the first quarter 2008, an increase of 31% from $84.8 million in the first quarter 2007, which included large maritime orders as well as strong aerospace orders. Sequentially, this segment’s orders grew 19% and ending backlog grew 17% to $159.5 million. This segment’s operating margin for the first quarter 2008 was 11.3% compared to 7.9% in the first quarter of 2007, and

8.3% in the fourth quarter of 2007. Compared to the first quarter of 2007 improvement primarily came from price, mix of shipments and productivity.

Circor’s Energy Products segment revenues increased by $8.2 million, or 10%, to $88.1 million for the quarter ended March 30, 2008 compared to $80.0 million in the quarter ended April 1, 2007. Higher foreign exchange rates, primarily the higher Euro, compared to the US dollar, accounted for $7.2 million of the incremental revenue increase. Incoming orders for the quarter were $125.9 million, an increase of 23% over $102.1 million in the first quarter of 2007 and 63% sequentially with ending backlog totaling $292.6 million, a 51% increase compared to $194.3 million at the end of the first quarter 2007, and 15% sequentially. This segment’s operating margin was 16.2% during the first quarter of 2008 compared to 12.7% for the first quarter of 2007 and 15.3% for the fourth quarter of 2007. The first quarter of 2008 benefited from high margins on some large international oil and gas projects as well as favorable currency impacts.

Bill Higgins, Circor’s President and Chief Executive Officer, said, “Our first quarter results exceeded our expectations as a result of strong global markets, a great mix of shipments and margin expansion in both segments. Globally, our oil and gas markets have remained solid. Large project quotations continue at a high level and the North American short-cycle business orders rebounded with our backlog growing over the fourth quarter 2007. Meanwhile, orders for our Instrumentation and Thermal Fluid Controls Products were also strong especially in aerospace where the markets continue to look solid as well as maritime orders where we won some large naval related orders to be shipped in 2009 and 2010.”

Mr. Higgins added, “The most notable area of improvement in the quarter was our healthy segment operating margins (which exclude corporate and special charge expenses) at 13.8% which was the highest since Circor became public at the end of 1999. Although we will still have quarters that are up and down, the focus on operational excellence and lean manufacturing over the past few years, leadership development, strong customer markets, favorable currency, as well as positive product and project mix all have contributed to the great results. ”

Circor provided guidance for its second quarter 2008 results, indicating it expects earnings to be in the range of $0.74 to $0.83 per diluted share, excluding special charges. The guidance compares favorably to earnings in the second quarter 2007 of $0.60 per diluted share.
