(NASDAQ: ROCK), demonstrates a heavily concentrated in-store retail presence with menards.com and lowes.com commanding 91.9% of combined revenue share according to Grips Intelligence data from January through August 2026. The brand's average product price stands at $8.88, though premium offerings reach up to $35.38 across its corrugated pipe product lines tracked on major retail channels. However, performance metrics reveal concerning headwinds, with overall revenue declining 20.7% since the beginning of the tracked period, while the most recent month showed a 4.3% sequential drop. Price erosion remains modest at a 2.6% monthly decrease, suggesting the revenue decline stems from volume pressure rather than pricing dynamics in the competitive drainage solutions market.
