Grainger (GWW) Q3 2026 earnings review
Grainger's volume and profit climb, but shipping costs squeeze North America
Grainger, the distributor of workplace maintenance and repair supplies, accelerated sales and held its profit margin without last quarter's tariff refund. Underlying daily sales grew 15% from a year ago as North American shipping volume rose by double digits and online growth stayed near 19%. Chief executive D.G. Macpherson raised the full-year outlook for a third time, and by our math the plan points to 14% underlying daily sales growth in the fourth quarter.
| Daily sales from continuing businesses, constant currency | +14.9% +13.7% last quarter |
|---|---|
| Operating margin, excluding one-offs | 16.1% +0.9 percentage points from a year ago |
| Profit per share, excluding one-offs | $12.54 +22.8% from a year ago |
| Full-year revenue outlook | Raised $350M middle of the range: $19.9B (+10.9%) |
⚖️ Verdict: 🟢 Bullish
The story got better because the industrial distributor proved its 16.1% operating margin and double-digit sales growth did not depend on one-off tariff refunds or Japanese pre-buying. Lower overhead costs and online scale covered the loss of last quarter's 0.9-point refund benefit. One caution: shipping expenses and lower-margin bulk orders pushed North American gross margin down 0.3 percentage points.
The question now is whether September's price increases can reverse the gross-margin squeeze in North America while large construction projects outgrow everyday maintenance orders. Either the new pricing restores margin parity by year-end, or free-shipping contracts and bulk project mix keep eroding gross profit per order. Fourth-quarter gross margin, implied at 39.7% by our math, will settle it.
🐂 Bull Case
North American Volume Accelerates Beyond Price
"The third quarter performance reflects our consistent execution and an improving demand environment," chief executive D.G. Macpherson said. High-Touch Solutions in North America, Grainger's main business serving large and mid-sized facilities with dedicated sales reps, makes up nearly four-fifths of total revenue. Critics argued that recent growth came mostly from passing tariff costs on to buyers rather than selling more goods.
Third-quarter sales in North America rose 13.8% on a daily, constant-currency basis, stepping up from 11.7% in the second quarter and 10.0% in the first. Grainger said the gain came from "double-digit volume growth and continued price inflation as cost increases were passed". With price increases running near 4% in prior quarters, shipping volume in North America is now growing at least 10% on its own.
What to watch: North American daily sales growth in the first half of 2027, when the industrial supplier laps this year's 10.0% and 11.7% gains. Holding high-single-digit growth against those tougher comparisons would show that customer demand remains durable.
Operating Margin Holds 16.1% Without Tariff Refunds
Last quarter, a one-time $43 million tariff refund lifted gross margin by 0.9 percentage points and helped push operating margin to 16.1%. Without that refund in the third quarter, the prior outlook pointed to operating margin dropping back to around 15.5%. Instead, operating margin excluding one-offs stayed at 16.1%, up 0.9 percentage points from 15.2% a year ago.
Lower overhead carried the quarter. Selling, general and administrative expenses — payroll, marketing and warehouse overhead — fell 0.7 percentage points of revenue to 22.7%, excluding $8 million of acquisition costs. The distributor credited "sales leverage in both segments and a benefit related to the Company's exit from the U.K. market". The full-year operating margin forecast rose to 16.0%–16.2%, proving the 16% level did not rely on tariff refunds.
What to watch: fourth-quarter operating margin excluding one-offs, which the full-year outlook puts at 15.5% by our math. Beating that seasonal dip would show overhead discipline is offsetting holiday cost pressures.
Online Unit Lifts Margin Target a Third Time
Endless Assortment is Grainger's online-only segment, made up of Zoro in the US and MonotaRO in Japan, offering millions of items to smaller businesses. Last quarter's 20.6% underlying daily sales growth included a temporary $45 million buying rush for petroleum products in Japan. Even after that rush faded, third-quarter daily sales from continuing businesses rose 19.3% in constant currency, and segment gross margin expanded 0.9 percentage points.
Because the online platforms are scaling without adding matching overhead, management raised the segment's full-year operating margin outlook to 10.9%–11.1%, up from 10.4%–10.8% in August and 10.0%–10.5% at the start of the year. What to watch: standalone operating margins for Zoro and MonotaRO in the quarterly filing. Continued margin gains at Zoro would confirm the US online business is closing its profitability gap with Japan.
🐻 Bear Case
Freight and Mix Still Squeeze Core Gross Margin
Grainger implemented an extra round of price increases in September to cover rising shipping bills and Middle East product costs, aiming to neutralize the drag on profitability. While total company gross margin rose 0.2 percentage points to 38.8% on online gains and last year's UK exit, the core North American business moved the other way.
In High-Touch Solutions, gross margin fell 0.3 percentage points from a year ago to 40.8%, which the release blamed on "unfavorable freight expense and mix". Large customers and construction projects buy in bulk at lower margins, and many large contracts include free parcel shipping that forces the distributor to absorb fuel costs until contracts renew.
Consequently, management trimmed the top end of its full-year North American operating margin plan from 17.6% to 17.5%, even while raising the rest of the company's outlook. Faster volume growth in the core business is coming from lower-margin orders.
What to watch: High-Touch Solutions gross margin in the fourth quarter, when the September price increase is in effect for all three months. Another year-over-year drop would show that project mix and shipping costs are outrunning the price hikes.
Risks this quarter didn't answer
Four standing concerns from prior quarters received no new numbers in the third-quarter earnings release and await the conference call or quarterly filing.
- Data-center project share: previously sized at 0.9 percentage points of North American growth; the call will show if cyclical project work drove the jump to 13.8%.
- Volume outgrowth versus the market: missed its 4 to 5 percentage point annual target two years running; only disclosed annually on an internal model.
- Price vs volume by segment: the release notes "double-digit volume growth" in North America, but exact price points and private-label tariff costs require call commentary.
- Permanent finance chief search: Laurie Thomson remains Vice President and Interim CFO alongside her controller duties; a permanent hire would resolve the dual-role concentration.

🔮 Guidance
Raised. The middle of the range moved up $350 million to $19.9 billion, or 10.1%–11.6% reported growth. By our math, that leaves $4.96 billion for the fourth quarter, up 12.0% from a year ago against an easy government-shutdown comparison. It is the third raise this year: +$500M in Q1, +$150M in Q2, and +$350M in Q3.
Raised. The middle of the underlying daily growth plan moved up 1.5 percentage points to 13.75%, after raising 3.0 points in Q1 and 1.5 points in Q2. By our math, the outlook implies about 14.2% underlying daily growth in the fourth quarter, down slightly from 14.9% in the third quarter.
Raised. Grainger lifted the bottom of the range by 0.1 percentage points, putting the middle at 39.5%, up 0.3 to 0.45 points from 2025. By our math, after a 38.8% margin in the third quarter, the full-year plan requires fourth-quarter gross margin to rebound to about 39.7%.
Raised. The floor rose 0.2 percentage points, moving the middle of the range to 16.1%. By our math, that leaves about 15.5% for the fourth quarter, down from 16.1% in the third quarter on normal seasonal expense patterns but up 1.2 points from last year's fourth quarter.
Raised. The middle of the range climbed $1.13 to $47.50, or 20.3% growth for the year. By our math, the plan leaves $11.30 per share for the fourth quarter, up 19.7% from $9.44 a year ago. Third raise this year: +$1.75 in Q1, +$1.13 in Q2, and +$1.13 in Q3.
Raised. The middle of the range increased $75 million to $2.40 billion. With $1.84 billion generated in the first nine months, the plan leaves $556 million for the fourth quarter by our math, down from $661 million in Q3 but 40.8% above last year's $395 million.
Trimmed. Management lowered the top of the capital spending range by $25 million, moving the middle to $600 million. By our math, after spending $396 million in the first nine months, the plan implies $204 million of warehouse and equipment spending in the fourth quarter, up from $115 million in Q3.
Trimmed. The top end came down $25 million, putting the middle of the range back at $1.00 billion. Having repurchased $739 million through September, the US group has $261 million left for the fourth quarter at the middle of the range, by our math.
Lowered. The expected full-year tax rate dropped 0.3 percentage points after third-quarter tax credit benefits brought the quarterly rate down to 24.3%, compared with 24.8% a year ago.
Narrowed. Both ends of the range moved in by 0.1 percentage points, keeping the middle unchanged at 17.4% as volume leverage balances freight and mix pressure on gross margin.
Raised. The middle of the range jumped 0.4 percentage points to 11.0%. It is the third raise this year (+0.15 pts in Q1, +0.20 pts in Q2, +0.40 pts in Q3) as both MonotaRO and Zoro expand gross margins and scale overhead.
