Home Depot warns volatile fuel, tariff costs are squeezing margins

Home Depot’s latest cost pressure is not just an investor concern. It is the kind of squeeze that can change what associates hear on the sales floor, how department leads explain substitutions, and how quickly product reaches a store or a customer.

Richard McPhail said fuel, interest rates, tariffs and other commodity costs are adding pressure, and that the environment is more volatile than it was only a few months ago. Transportation expense is a meaningful part of Home Depot’s books, which makes diesel prices and freight disruption matter in practical terms. When shipping costs move, stores can feel it in inventory timing, backorder explanations and more conversations about whether a customer can get the same item, a close substitute, or a delayed delivery.

The pressure is showing up against a still-growing sales base. Home Depot reported first-quarter fiscal 2026 sales of $41.8 billion, up 4.8% from a year earlier. Comparable sales rose 0.6%, with U.S. comparable sales up 0.4%. Adjusted diluted earnings per share came in at $3.43, down from $3.56 in the same period a year ago. Ted Decker said underlying demand was “relatively similar” to fiscal 2025 even as consumer uncertainty and housing affordability pressure increased.

Home Depot still reaffirmed full-year fiscal 2026 guidance for total sales growth of about 2.5% to 4.5% and gross margin of about 33.1%, with plans for about 15 new stores. The company ended the quarter with 2,361 retail stores and more than 1,280 SRS locations, a footprint that depends on a large, coordinated supply chain to keep bulky product moving.

That network is also why fuel and tariff swings matter so much inside the business. Home Depot’s fiscal 2026 10-K says its supply chain network is a competitive advantage and notes distribution-center platforms in the United States, Canada and Mexico. The size and spread of that system help explain why cross-border trade conditions, freight rates and sourcing changes can quickly turn into store-level issues.

Tariffs have been a live issue for more than a year. Home Depot said in March 2025 that tariffs present challenges to profitability, and later reporting said the company was working with suppliers to keep prices steady and shift sourcing so no single country outside the U.S. would represent more than 10% of purchases within 12 months. For store teams, that longer-running effort now intersects with fuel costs and a more unsettled operating backdrop, raising the odds that pricing consistency, substitutions and delivery timing stay front and center in daily customer conversations.
