PORTLAND, OR--(Marketwire - October 24, 2007) - Northwest Pipe Company (NASDAQ: NWPX) today reported its quarterly results for the third quarter of 2007. Sales were $92 million for the quarter, approximately the same as for the third quarter of 2006. Net income, however, was substantially higher at $5.1 million for the third quarter of 2007, compared to $4.1 million for the third quarter of 2006.

Water Transmission

Sales in the Water Transmission Group for the third quarter of 2007 were $63.9 million compared to $65.5 million for the third quarter of 2006. Gross profit was $14.3 million, or 22.5% of sales, compared to $12.7 million, or 19.4% of sales in the third quarter of 2006.

"Sales were a little less than our expectations. Margins, however, were very strong, reflecting a positive mix of projects as well as general improvements in productivity," said Brian W. Dunham, president and CEO of the Company.

Tubular Products

The Tubular Products Group's sales were $25.2 million in the third quarter of 2007 compared to $22.3 million for the third quarter of 2006. Gross profit increased to $3.1 million, or 12.2% of sales, compared to $2.2 million, or 10.1% of sales for the same period last year.

Fabricated Products

Sales in the Fabricated Products Group were $2.9 million in the third quarter of 2007 compared to $4.7 million for the same period in 2006 and the Group reported a small loss. "Volume in our propane tank business was dramatically lower and we have not yet added enough pipe fittings work to offset this decrease. We expect to see these results improve in the future," said Dunham.

Fourth Quarter Outlook

The Company is continuing to forecast a stronger fourth quarter in its Water Transmission Group in overall volume. The significant improvement in margins exhibited in the third quarter, however, is not likely to be repeated. "The margin improvement was partially due to a positive mix of projects as indicated earlier," said Dunham. "Based on our current schedules, the mix will not be as favorable in the fourth quarter. Margins should still exceed last year's comparative results, but will not be as strong as the third quarter's margins."

"As we have said previously, we expect the Tubular Products Group to have lower sales in the fourth quarter as a result of normal seasonality. Additionally, we will not be continuing our strategic alliance with U.S. Steel," stated Dunham. The U.S. Steel alliance began in 2005 with Lone Star Steel, who U.S. Steel subsequently acquired. In this arrangement, the Company produced pipe for the oil and gas industry under Lone Star's label and Lone Star distributed these products. "The termination of this arrangement has impacted our backlog and will also impact our near term sales and earnings," noted Dunham. "However, we are pleased to announce that we have signed an agreement with a new sales and marketing company for energy tubular products, LSS Group of Houston, Texas. We believe we will be back in the market with our products under our own name in the near future."

The Fabricated Products Group is expected to increase sales slightly over its current level and generate a small positive margin in the fourth quarter. "We now have several pipe fittings projects slated for this facility," stated Dunham. "However, we will not see much change in volume or profitability until next year."

Longer Term Outlook

The Company reported a backlog of $174 million as of September 30, 2007 compared to $195 million at September 30, 2006. "While our backlog is lower, as expected, the fourth quarter should be a strong bidding quarter and we are forecasting an increase in the backlog by the end of the year," said Dunham. "Furthermore, the 2008 market continues to look very strong and we are continuing to focus on building our capacity to address the opportunities we expect in the years ahead."

The Company announced the acquisition of Continental Pipe, in Pleasant Grove, Utah, last quarter and is pleased to announce its plans for further expansion at this time. "We have agreed to purchase two new state-of-the-art spiral weld pipe mills from Wilson Byard, Ltd.," Dunham announced. "These mills will be built jointly by Wilson Byard and Northwest Pipe in our Adelanto, California facility. One of the mills will remain in Adelanto, while the other will be designed to be relatively transportable and will ultimately be deployed at a location to be named later."

The Company is also in the process of acquiring additional acreage adjacent to its Saginaw, Texas facility. This land will be used to reconfigure some manufacturing operations and future expansion.
