What this transaction means for investors

NWPX has been firing on all cylinders, recently reporting consolidated net sales of $159.5 million for the second quarter of 2026, a 19.7% increase from the prior-year period. It also recently raised its full-year revenue for 2026 from a previous range of $50 million to $56 million to a new range between $56 million and $65 million. Over the last 12 months, the stock price has skyrocketed 111% as of this writing. In comparison, during the same period, the S&P 500 is up 18.9%.

With Larson's sale, this appears to be nothing more than a routine stock sale, as it was pre-established. He still maintains 21,133 directly, indicating he still has a significant stake in the company's success. NWPX doesn't receive much analyst coverage, but according to CNN, the two analysts who rate it both rate it a hold. Also, the median one-year price target among those analysts is $108, with the highest at $130 and the lowest at $95. Given how the stock price has climbed over the past year, those targets, even the $130 price target, suggest shareholders should keep their expectations in check over the next 12 months.
