Hammermill

Hammermill Market Overview

According to Grips Intelligence in-store data tracked across Amazon, Newegg and Office Depot from January 1 to September 30, 2026, Hammermill — a brand of Sylvamo Corporation (NYSE: SLVM) — posted revenue growth of 15.4% over the period, with a 4.4% month-over-month gain in the most recent reading. Amazon dominates the brand's measured footprint at 90.9% of year-to-date revenue, leaving Newegg at 6.5% and Office Depot at just 2.6%. Pricing has firmed alongside volume, with the average price rising 7.5% across the period to $44.01, including a 4.8% month-over-month increase. That recent figure sits above the $40.92 year-to-date average price, suggesting a mix shift toward larger, higher-ticket assortments. The combination of simultaneous revenue and price gains points to demand holding up even as per-unit costs climb, though the heavy single-channel concentration remains the brand's key structural risk.
