Did O'Reilly's growth come from professional or DIY customers?

Both contributed. Sales to professional service providers rose about 9% to $2.20 billion in Q2 (from $2.01 billion), while DIY sales rose about 4% to $2.23 billion. Professional sales are growing faster, which supports the company's commercial focus.

Why did operating margin stay flat despite higher gross margin?

Gross margin improved 70 basis points to 51.4%, but SG&A grew 8% versus 6% sales growth, rising to 31.2% of sales from 30.5%. The expense growth offset the gross margin gain, leaving operating margin at 20.2%.

Is the raised comparable store sales guidance a sign of stronger trends?

The company raised its full-year comp range to 3.0%-4.5% and cited the sales trends it is currently seeing. Q2 comps of 4.1% and H1 comps of 3.9% support that view, though the company did not reissue specific quarterly targets, so the second-half run rate will determine whether the raised range is achieved.

Why did free cash flow decline, and is it a concern?

H1 free cash flow fell to $904 million from $1.16 billion, driven by lower operating cash flow (working capital outflows in inventory and other operating items, partly offset by higher payables and taxes) and higher capex ($588 million vs. $475 million). Full-year FCF guidance of $1.6-$1.9 billion implies a strong second half, which is a key item to monitor.

ORLY 8-K: Earnings & Results

01—Abstract

Summary

Summary of the 8-K filed July 23, 2025. Cited figures are marked; the original filing is the authoritative source.

O'Reilly Automotive reported record second-quarter 2025 sales of $4.53 billion^a, up 6% year over year, with comparable store sales up 4.1% on top of a 2.3% gain a year earlier.

Growth was driven by both professional (sales to professional service providers rose about 9%) and do-it-yourself customers (up about 4%). Gross margin expanded 70 basis points to 51.4%, but SG&A grew faster than sales, to 31.2% of sales from 30.5%. As a result, operating margin was flat at 20.2% and operating income rose 6% to $914 million^b.

Diluted EPS increased 11% to $0.78^c, helped by a 3% reduction in diluted share count (858 million versus 886 million) and a 15-for-1 forward stock split completed June 10, 2025. Per-share figures in the release are split-adjusted. Management raised full-year 2025 comparable store sales guidance to 3.0%-4.5% and reiterated diluted EPS guidance of $2.85-$2.95, total revenue of $17.5-$17.8 billion, and 200-210 net new stores.

Cash generation weakened in the first half: operating cash flow was $1.51 billion^d versus $1.65 billion, capital expenditures rose 24% to $588 million, and free cash flow fell 22% to $904 million. The company continued to return capital, repurchasing $617 million of stock in Q2 and $1.18 billion year to date, with about $1.16 billion remaining under its authorization. Leverage is rising modestly, with adjusted debt to EBITDAR at 2.06x versus 1.97x a year ago, and the balance sheet still carries a shareholders' deficit of about $1.23 billion because of cumulative buybacks.

Overall, the quarter shows solid top-line momentum and share gains with steady EPS growth, supported by buybacks. The main watch items are flat operating margins, weaker first-half free cash flow, and inventory growth, with inventory up about 6% year over year and turnover slipping to 1.6x from 1.7x.
