Fastenal (FAST) Posts Strong Gross Margins, but Revenue Growth Decelerates

Fastenal (NASDAQ:FAST) maintains elite unit economics, but slowing revenue growth warrants investor caution, according to a May 29, 2026, analyst report. Shares of the industrial and construction supplies distributor have risen 11.5% over the past six months, in line with the S&P 500’s 10.3% gain. Unit volumes averaged 9.1% annual growth over the past two years, reaching 137,702 in the most recent quarter, highlighting steady demand for its fasteners, tools and safety products. Fastenal’s five-year average gross margin of 45.5% reflects pricing power and differentiated offerings rather than commodity goods. However, annualized revenue growth over the past two years slowed to 6.9%, below the company’s five-year trend, suggesting a potential demand shift. Shares trade at $44.76, or 35.1 times forward earnings.
