What Happened in the Quarter

The company reported third-quarter results on October 14, 2026, and filed its quarterly report on October 19, so the October 19 session had no new earnings news. Net sales rose 15.5% to USD 2.463 billion, daily sales grew about 16% to USD 38.5 million and net income climbed 19.7% to USD 401.6 million, or USD 0.35 per share. Management said contract sales grew 19% and large customer sites kept growing. Shares fell about 0.7% to USD 51.65 in premarket trading on the day, and one report showed a deeper dip near USD 49.50 before the open. The 52-week high is implied at about USD 52.9 from the 3.6% gap, simple arithmetic on published market data.

September Moderation and Margin Mix

Executives described September, at 14.4% daily sales growth, as a moderation from very strong levels, not a change in customer activity, noting that pricing is starting to lap and that two-year growth is 27%. Gross margin fell about 40 basis points as the shift toward larger customers cut roughly 50 basis points and price and cost cut about 30, while sourcing savings, supplier rebates and tariff refunds helped. Heavy manufacturing grew above 20% in the quarter, while non-residential construction slowed, and agriculture and food were weak. Nine-month net sales rose 14.2% to USD 7.05 billion, including pricing of about 290 basis points. Large customers carry lower gross margins but lift operating margin through fixed-cost leverage.

Risks, Analysts and What to Watch

The risk is deceleration. September growth ran below July and August, price increases are being lapped, and about 20 basis points of the quarter's gross margin benefit came from timing. Analyst views diverge: Baird kept Outperform and raised its target to USD 60 from USD 59, while Bernstein kept Underperform and raised its target to USD 47 from USD 42, below the price. The company still expects 2026 net property and equipment investment of USD 310 million to USD 330 million and an ongoing tax rate of about 24.6%. Watch monthly sales updates, the pace of price and cost, signs of slowing in industrial production and any change in how larger customers shift the margin mix.

Where Things Stand

Sales growth of 15.5% beat estimates, but the shares are 3.6% below a high because September slowed, margins on mix slipped and the price run is being lapped. The balance of evidence shows strong share gains from large customers, offset by tougher comparisons. The next catalysts are monthly sales and the next quarterly report. This is not investment advice, and distributor demand follows industrial activity.
