Management Commentary

“The third quarter of 2026 was another outstanding quarter for NWPX Infrastructure, highlighted by record financial performance across several key metrics,” said Scott Montross, President and Chief Executive Officer of NWPX Infrastructure. “We generated record quarterly revenue of $179.4 million and record gross profit, representing a consolidated gross margin of 21.3%, along with earnings per diluted share of $1.86. These results reflect the strength and resilience of our businesses, disciplined execution across our operations, and our continued ability to capitalize on favorable market conditions. WTS led our performance, delivering record revenue and record gross profit with a strong gross margin of 20.7%. WTS backlog including confirmed orders reached a record $435 million, even after recognizing $31.0 million in revenue associated with our NDA project during the quarter, providing excellent visibility into future production activity. Precast also delivered solid results, with revenue and gross profit exceeding the prior year, and an approximate 160-basis point improvement in gross margin to 22.9%. We are particularly encouraged by the continued growth of our data center business, which continues to represent an attractive opportunity within our Precast segment.”

Mr. Montross continued, “As we look ahead, we remain very optimistic about the strength of our business and our opportunities for continued success. Despite the typical impact of two major holidays and weather-related disruptions in the fourth quarter, we currently anticipate stronger performance than both the fourth quarter of 2025 and the first quarter of 2026. We expect WTS backlog to remain elevated through year-end, supported by continued demand for critical water infrastructure, while our Precast business is expected to remain steady. Taken together, we believe our record backlog and attractive opportunities across our businesses position NWPX Infrastructure to conclude an exceptionally strong record year in 2026 and enter 2027 with significant momentum.”

Water Transmission Systems Segment (WTS)

• WTS net sales increased 27.0% to $131.9 million from $103.9 million in the third quarter of 2025 driven by a 19% increase in selling price per ton due to changes in product mix and a 7% increase in tons produced resulting from changes in project timing.

• Net cash provided by operating activities was $27.4 million in the third quarter of 2026 compared to $21.0 million in the third quarter of 2025 primarily due to a $5.6 million increase in net income adjusted for noncash items and a $0.8 million increase in net cash provided by changes in working capital.
