W.W. Grainger (GWW) Q2 FY2026: Revenue $5.0B, EPS $12.01 Up 20.5% — Tariff Refund Drove Most of the Gross-Margin Gain

Revenue rose 10.3%, operating profit 19.0%, and diluted EPS 20.5% year over year. W.W. Grainger, North America's largest industrial MRO distributor, reported second-quarter 2026 revenue of $5.021 billion, operating profit of $807 million, and net income of $600 million. Of that net income, $570 million was attributable to Grainger shareholders and $30 million to non-controlling interests. Gross margin expanded 100 basis points (hundredths of a percentage point) to 39.5% from the year-ago quarter. At the August 4 earnings release, the company said $43 million in IEEPA tariff refunds on directly imported products had reduced cost of goods sold. That amount equals 86 basis points of revenue — accounting for most of the 100-basis-point margin expansion. Diluted earnings per share rose 20.5% to $12.01 from $9.97. The company raised its full-year 2026 guidance on the same day.

1. Balance Sheet: Receivables Surge 21% as Revenue Grows, Inventory Turns Improve

1-1. Key Asset Items: Year-End 2025 vs. Mid-Year 2026 ($ millions)

Analysis: Accounts receivable jumped 21.3%, far outpacing the 10.3% revenue gain. The 10-Q gives no separate explanation for the increase. Both a higher share of large corporate accounts and a longer collection cycle are plausible causes — the next quarter will clarify the picture. The allowance for doubtful accounts rose only modestly, to $33 million from $32 million, so credit risk appears contained for now. Inventories fell 1.0% while revenue grew 10.3%. That combination signals a meaningful improvement in inventory turnover — a key performance metric for MRO distributors.

1-2. Debt Improved on the Financial Side; Payables Jumped 33% on the Operating Side

Financial debt consists of long-term borrowings of $2.406 billion (vs. $2.362 billion at year-end, +1.9%) and short-term debt of $2 million (vs. $126 million, -98.4%). The largest single item is $1 billion of 4.60% Senior Notes due 2045. MonotaRO drew a new ¥7.5 billion term loan in 2026 — at a weighted-average rate of 1.74% — to fund distribution-center (DC) expansion. In 2025, MonotaRO borrowed ¥13 billion for the same purpose. The new draw is an extension of a running investment cycle, not a one-time event. The sharp drop in short-term debt reflects net repayment of $124 million in commercial paper. The total debt-to-total-capital ratio improved to 34.8% from 37.5% at year-end.

On the operating side, accounts payable surged to $1.280 billion from $963 million (+32.9%). Natural growth from higher purchasing volumes is one driver. Renegotiation of purchase terms — as the company adjusts sourcing strategy in response to shifting tariff conditions — is a plausible additional factor, though the 10-Q does not state this explicitly. Accrued compensation ($347 million) and accrued expenses ($389 million) were broadly in line with year-end.

1-3. Equity Up 10.6% as Earnings Accumulation Outweighs Buyback Pressure

Retained earnings of $15.858 billion — up from $14.958 billion at year-end — stand 10.6 times larger than paid-in capital of $1.503 billion. Paid-in capital comprises common stock of $55 million and additional paid-in capital of $1.448 billion. That ratio is typical of a long-profitable, mature company. Treasury stock widened to -$13.032 billion from -$12.558 billion, a $474 million increase, with $461 million attributable to first-half repurchases.

Equity attributable to W.W. Grainger, Inc. shareholders rose 10.6% to $4.131 billion from $3.736 billion. Adding non-controlling interests of $382 million — down from $405 million after $70 million in NCI buybacks during the half — brings total equity to $4.513 billion, up 9.0%. Accumulated other comprehensive loss widened to -$198 million from -$165 million. The primary cause was foreign-currency translation losses as the yen weakened.

2. Income Statement: Operating Margin Reaches 16.1%, Tariff Refund the Biggest Single Driver

2-1. Key Earnings Metrics, Q2 2026 ($ millions)

Analysis: Revenue grew 10.3%. Strip out working-day adjustments, foreign-exchange effects, and the UK divestiture, and organic growth was 13.7%. Both segments contributed: High-Touch Solutions N.A. (HTSNA) on volume, and Endless Assortment (EA) on repeat purchases and enterprise customer additions.

One point of clarity on the $12.01 EPS: the numerator is not consolidated net income of $600 million. It is the $570 million attributable to Grainger shareholders. The remaining $30 million belongs to minority owners — primarily MonotaRO shareholders.

The 120-basis-point expansion in operating margin is the headline result. Breaking it down: 100 basis points came from gross margin and 20 basis points from a lower selling, general, and administrative (SG&A) ratio. Five-sixths of the margin gain originated at the gross-profit line. HTSNA gross margin rose 80 basis points to 41.8%. The 10-Q attributes this to tariff refund gains, partly offset by higher freight costs. The effective tax rate rose to 24.8% from 23.2% a year earlier — a 160-basis-point increase driven by 2026 tax-law changes and reduced credit activity.

2-2. Cost Structure: Tariff Refund Accounts for 86 of the 100 Gross-Margin Basis Points

Cost of goods sold was $3.037 billion, or 60.5% of revenue, down from 61.5% a year earlier. Cost growth of 8.5% lagged revenue growth of 10.3%, producing the 100-basis-point improvement in gross margin. Decomposing that 100 basis points: the $43 million IEEPA tariff refund accounts for 86 basis points on its own. The remainder reflects Zoro discount adjustments and a better product mix within EA, whose gross margin expanded 90 basis points to 30.7%. Higher freight costs worked in the opposite direction.

SG&A was $1.177 billion, or 23.4% of revenue, down from 23.6%. Labor and benefits were the main cost drivers. The exit from the UK partially offset those, holding SG&A growth to 9.3% against the 10.3% revenue gain. Fixed-cost leverage contributed 20 basis points to operating-margin expansion — a supporting role, not the main story.

The $43 million refund represents roughly one-third of the $129 million operating profit gain. Exclude it and operating profit still grew an estimated $86 million, or approximately 12.7%. Saying the company had no real growth without the refund overstates the case. More precisely: the refund added roughly 6-7 percentage points to what was already double-digit profit growth. Depreciation and amortization were stable at $85 million for the quarter, up from $84 million a year ago.

3. Cash Flow: FCF Grew 25% to $902 Million; Receivables Growth Bears Watching (H1 2026, $ millions)

Operating cash flow of $1.183 billion was driven by net income growth of $173 million. A $496 million increase in accounts receivable (vs. $212 million a year earlier) weighed on working capital (the gap between current assets and current liabilities). Growth in accounts payable of $317 million and a $23 million inventory reduction partly offset that drag.

Free cash flow (FCF — operating cash flow minus capital expenditures) came to $902 million: $1.183 billion in operating cash flow less $281 million in CapEx. That is up 24.8% from $723 million in the prior-year period. Cash generation improved meaningfully.

Net investing outflows widened slightly to $294 million from $283 million. CapEx itself fell to $281 million from $300 million. Other investing items swung from a $17 million inflow to a $13 million outflow, producing the net increase. The 10-Q describes total investing activity as supply-chain investment at a level similar to the prior year. Given that MonotaRO's new ¥7.5 billion term loan funds DC expansion, the investment cycle appears to have further to run.

Major financing outflows were share repurchases of $461 million, dividends of $225 million, NCI buybacks of $70 million, and net commercial paper repayment of $124 million. Despite those outflows, financing outflows narrowed by $327 million versus the prior year. The prior-year period included a $500 million repayment of 1.85% Senior Notes at maturity.

4. Beyond the Headlines: Five Factors Shaping the Second-Half Outlook

① $43 Million in Tariff Refunds — Recurrence Is the Key Question

At the August 4 earnings release, Grainger stated that IEEPA tariff refunds on directly imported products reduced cost of goods sold by $43 million. That is the real source of HTSNA's 80-basis-point gross-margin expansion. The company has not labeled the refund a one-time item. New tariff risks, however, are growing. Grainger disclosed it is "adjusting its sourcing strategy, managing costs, and adjusting customer pricing."

Structurally, a tariff refund returns duties already paid — it is not a recurring cost-reduction lever. Assuming the same magnitude repeats every quarter is a risky baseline. At $43 million, the refund equals 5.3% of quarterly operating profit. If absent in the second half, operating margin would face roughly 86 basis points of reversal pressure, all else equal. It is the single biggest variable for margin sustainability in coming quarters.

② MonotaRO in Japan — The Hidden Growth Engine

Endless Assortment segment revenue rose 13.5% to $1.054 billion in Q2. On an organic, working-day-adjusted, constant-currency basis — constant currency meaning growth measured at fixed exchange rates — EA expanded 20.6%. That result came despite roughly 7 percentage points of headwind from a weaker yen.

First-half Japan revenue was $1.219 billion, up 17.0% from $1.042 billion. That outpaced the U.S. segment's 11.7% growth to $7.992 billion. New DC investment and enterprise customer expansion are driving the outperformance. EA operating profit rose 31.5% to $121 million, well ahead of the company-wide 19.0% gain.

③ UK Exit Complete — Restructuring Wrapped Up

The Q4 2025 sale of Cromwell and closure of Zoro UK eliminated Grainger's European exposure. In Q2 2026, HTSNA ($3.967 billion) and EA ($1.054 billion) together match total reported revenue ($5.021 billion) almost exactly. The Other segment's revenue contribution has effectively disappeared. SG&A savings from the exit have already been realized.

④ Shareholder Returns: $686 Million in the First Half

First-half share repurchases of $461 million plus dividends of $225 million totaled $686 million returned to shareholders. That equals 61.0% of first-half net income attributable to Grainger shareholders ($1.125 billion), or 58.1% of consolidated net income ($1.181 billion). In Q2 alone, the company returned $313 million.

The quarterly dividend was raised 10.2% to $2.49 from $2.26, effective with Q2 2026 payments. On July 29, the board declared the same $2.49 per share, payable September 1. The company's 2026 share repurchase guidance stands at $975 million to $1.050 billion.

⑤ Rising Effective Tax Rate — A Persistent Headwind

The effective tax rate rose to 24.9% in H1 2026 from 23.5% in the prior-year period. Tax-law changes and reduced credit activity drove the increase. It represents an ongoing headwind to net margin.
