Scott J. Montross, President and CEO of Northwest Pipe Company (NWPX), has filed 53 Form 4 transactions in the covered period, all in that single stock. The pattern is one-sided on the sell side: his open-market sales total $2,484,059.39, with no open-market purchases recorded. The recent activity is concentrated in a series of weekly sales in August 2026, starting at $135,682.89 on August 31 and running backward through August 24 ($273,418.50), August 17 ($287,818.50), August 10 ($296,847.50), and August 4 ($321,546.50). Earlier in the year, he sold similar blocks in March, including $158,003.60 on March 30 and $178,600 and $181,200 on March 16.
The March filings also show grant and option activity. On March 31, Montross exercised options with no reported cash value and had shares withheld to cover taxes: $251,954.96, $308,792.76, and $308,481.32 in separate F transactions. On March 12, he received two awards with no value listed, and on January 15 he had additional tax withholdings of $68,508.03, $69,062.19, and $89,150.49 following option exercises. The F transactions are automatic and tied to compensation, not voluntary decisions.
The open-market sales are the sole voluntary trades. Every S transaction is an outright disposition, and there are zero P purchases. The August 2026 sequence shows increasing dollar amounts as the shares sold rise, but the direction across all filings is clear: Montross has been a consistent seller of NWPX stock, with no disclosed buyback or acquisition of shares on the open market. The sales span roughly $135,000 to $322,000 per transaction, and the nine most recent open-market sales all occurred in 2026.
