VANCOUVER, Washington—August 7, 2025—NWPX Infrastructure, Inc. (NASDAQ: NWPX) (the “Company”), a leading manufacturer of water-related infrastructure products, today announced its financial results for the second quarter ended June 30, 2025. The Company will broadcast its second quarter 2025 earnings conference call on Friday, August 8, 2025 at 7:00 a.m. PT.

As previously announced, effective June 12, 2025, the Company’s shareholders approved an Amendment to the Company’s Articles of Incorporation to change the corporate name from Northwest Pipe Company to NWPX Infrastructure, Inc. and, at the same time, the Company renamed one of its two operating segments. The segment previously referred to as “Engineered Steel Pressure Pipe (SPP)” has been renamed “Water Transmission Systems (WTS)” to better reflect the value contribution specifically from the business unit’s capabilities in engineering, production execution, and delivery of critical integrated water pipeline systems. The “Precast Infrastructure and Engineered Systems (Precast)” segment name remains unchanged. This change in naming convention does not affect the composition of the segments or the basis of segment reporting, as there have been no changes to how the Company’s chief operating decision maker manages or evaluates performance. Historical results have been recast to reflect the updated segment name for all periods presented.

Management Commentary

“In the second quarter, NWPX Infrastructure delivered record results, demonstrating strong operational execution and demand across both business segments,” said Scott Montross, President and Chief Executive Officer of NWPX Infrastructure, Inc. “We achieved consolidated revenue of $133.2 million, our highest ever for this configuration of the Company, driven by continued momentum in our WTS segment and record performance from our Precast segment. Gross margin expanded to 19.0%, up 230 basis points from the previous quarter, reflecting enhanced production efficiency and solid market demand.”

Montross continued, “WTS revenue reached $84.6 million with significant margin expansion due to higher production levels and improved overhead absorption versus the previous quarter. Backlog including confirmed orders surged to $348 million, an increase of over 20% compared to the end of the first quarter, setting the stage for sustained strength in the second half of the year. We anticipate third quarter WTS revenues and margins to remain in-line with or exceed the second quarter.”

“Additionally, our Precast segment delivered record revenue of $48.6 million, fueled by markedly higher shipping levels compared to the prior quarter. This performance led to a 210 basis point sequential improvement in our Precast gross margin. Our healthy order book and uptick in order velocity supports our expectation for Precast revenue to remain strong in the third quarter of 2025 with continued margin improvement,” concluded Montross.
