StockStory’s Take

W.W. Grainger’s second quarter saw revenue climb as the company navigated a challenging environment, but the market responded sharply negatively to the results. Management highlighted that tariff-related inventory accounting and price/cost timing issues weighed on profitability, particularly through LIFO (last-in, first-out) inventory impacts. CEO Donald Macpherson pointed out that demand from contractor and healthcare customers was a bright spot, offsetting muted trends elsewhere, while CFO Dee Merriwether emphasized that most margin pressure was transitory, stemming from accounting rather than operational weaknesses. The leadership acknowledged that underlying operations would have shown more robust earnings growth without the LIFO headwinds.

Looking ahead, management’s guidance remains cautious, with expectations for ongoing margin pressures due to continued tariff-related cost increases and the timing of price adjustments. CFO Dee Merriwether stated that gross margin will likely stay under pressure through the third quarter, but gradual recovery is expected as new pricing actions take effect, particularly in September. The company is also monitoring the impact of tariffs on private label economics and expects market demand to remain subdued in the near term. CEO Macpherson reiterated confidence in the long-term strategy, predicting that margin normalization and improved price/cost dynamics should materialize by late 2025 into 2026.

Key Insights from Management’s Remarks

Management attributed the quarter’s performance to volume gains in select customer segments and strength in digital and assortment-driven businesses, but profitability was hampered by inventory valuation and delayed pricing actions.

LIFO inventory accounting headwinds: Management repeatedly cited the LIFO accounting method as the main driver of year-over-year gross margin decline, with CFO Dee Merriwether stating, “The vast majority of the impact to us…is the LIFO impact,” and that, absent this, gross profit would have been flat.
Muted MRO market demand: The High-Touch Solutions segment experienced modest growth, with contractor and healthcare customers outperforming but the broader maintenance, repair, and operations market remaining softer than anticipated, which management does not expect to recover quickly.
Endless Assortment momentum: The Zoro and MonotaRO platforms delivered strong sales and operating leverage, attributed to customer acquisition strategies, improved repeat purchasing, and targeted assortment optimization, including pruning low-value SKUs to enhance experience and efficiency.
Measured pricing actions: To support customer stability, Grainger chose to delay some tariff-driven price increases until its regular September cycle. Macpherson explained this was to maintain loyalty and trust, even if it meant temporary price/cost mismatches.
Elevated supply chain investments: A $100 million increase in capital expenditures was directed mainly to supply chain improvements, reflecting a longer-term view on network evolution and operational resilience.

Drivers of Future Performance

Grainger’s outlook is shaped by ongoing tariff impacts, the timing of pricing adjustments, and persistent softness in core markets, with margin recovery hinging on price realization and normalized cost flows.

Tariff-related price/cost challenges: Management expects gross margin to remain pressured as tariff costs flow through inventory and price increases lag, particularly impacting the High-Touch business until pricing actions in September start to offset these costs.
Subdued demand environment: CEO Macpherson acknowledged that market demand, particularly in the industrial and manufacturing customer base, is likely to remain muted, impacting volume growth and limiting near-term operating leverage.
Assortment and digital execution: The company is relying on continued growth from the Endless Assortment segment and ongoing optimization efforts—such as SKU rationalization and targeted customer acquisition—to help offset pressures elsewhere, with management confident these initiatives will sustain above-market growth.

Catalysts in Upcoming Quarters

Looking ahead, the StockStory team will focus on (1) the pace and effectiveness of September pricing actions in offsetting tariff-driven cost increases, (2) whether gross margin begins to recover as LIFO impacts cycle out, and (3) ongoing growth and profitability in the Endless Assortment segment, especially as Zoro and MonotaRO execute on digital and assortment optimization. How Grainger adapts to evolving competitive and supply chain pressures will also be closely watched.

W.W. Grainger currently trades at $962, down from $1,040 just before the earnings. In the wake of this quarter, is it a buy or sell? See for yourself in our full research report (it’s free).
