WW Grainger's QQ3 2025 results show a solid top-line performance accompanied by notable profitability pressures. Revenue reached $4.657 billion, up 6.1% year over year and 2.3% quarter over quarter, signaling resilient demand for maintenance, repair and operating (MRO) products in a still-healthy industrial backdrop. Gross profit rose to $1.798 billion with a gross margin of 38.6%, and operating income of $511 million yielded an operating margin of 11.0%, indicating earnings retention even as costs rose. However, net income declined sharply to $196 million, down roughly 60% year over year and quarter over quarter, driven by increased cost structure and a material tax impact, resulting in earnings per share of $6.10 (diluted $6.09). A counterpoint to the margin headwinds is strong cash generation: operating cash flow per share was $12.44 and free cash flow per share was $7.06, supporting a payout ratio of 67.9% and a robust balance sheet (current ratio 2.72, debt-to-capitalization ~23.5%). The dataset does not include earnings-call transcripts or management quotes, limiting qualitative integration. Overall, Grainger demonstrates revenue durability with meaningful cash returns, though profitability in QQ3 2025 was constrained by expense dynamics and tax effects.
