O'Reilly Automotive delivered a strong second quarter of 2026 with comparable store sales up 6% (year-to-date 7%, total sales growth over 9%) and diluted EPS up 10% to $0.86, prompting the company to raise its full-year comp guidance to 4-6% and EPS guidance to $3.20-$3.30. GAAP revenue rose about 8% to $4.89 billion at a 20.2% operating margin. The professional (DIFM) business again led, growing right at 10% for a fourth consecutive double-digit quarter on mid-single-digit ticket-count growth, while DIY grew only low single digits as transaction counts fell and hot-weather categories were pressured by a wet, mild late spring — a headwind management said reversed strongly as summer heat arrived in July. Gross margin held flat at 51.4% against the toughest tariff-timing comparison of the year, and first-half free cash flow nearly doubled to $1.5 billion, funding $3.1 billion of year-to-date buybacks. Management set a cautious back-half tone: same-SKU inflation, which ran 5.5% in Q2, is expected to moderate to 1-2% as 2025 tariff-driven pricing is lapped, and leadership flagged consumer sensitivity to volatile oil and fuel prices while warning that July strength could partly reflect weather volatility. CEO Brad Beckham firmly declined to engage speculation about interest in a competitor, stressing O'Reilly's conviction in organic share gains given only ~10% penetration of a fragmented North American market, record vehicle counts and a ~13-year average vehicle age. The company reaffirmed 225-235 net new store openings, $1.3-1.4 billion of capex and $1.8-2.1 billion of free cash flow, and will host its Analyst Day at the new Atlanta distribution center on September 17.

Thanks, Jeremy. Good morning, everyone, and welcome to the O’Reilly Auto Parts second quarter conference call. Participating on the call with me this morning are Brent Kirby, our president, and Jeremy Fletcher, our chief financial officer. Greg Henslee, our executive chairman, and David O’Reilly, our executive vice chairman, are also present on the call. It's once again my pleasure to begin our quarterly call by congratulating Team O’Reilly on another strong quarter and a very successful first half of 2026. Our team's steadfast commitment to providing consistently high levels of service to our customers drove a comparable store sales growth of 6% for our second quarter. Year-to-date, our comparable store sales have increased 7% and driven total sales growth of over 9%.
As a result of our team's relentless focus on delivering profitable sales growth, we generated a 10% increase in diluted earnings per share in the second quarter on top of the 11% growth we delivered in the second quarter of 2025. For the first six months of 2026, our diluted EPS grew 13%, and I want to thank all of Team O'Reilly for the momentum they have created in our business so far in 2026. Now I'd like to take a few minutes to walk through the details of our second quarter comparable store sales performance. Our comp growth of 6% surpassed our expectations, driven by solid results in both our professional and DIY businesses. Our professional business continues to be the larger contributor to total comps, but we again saw the outperformance versus our expectations split evenly between both sides of our business, similar to first quarter results.
In aggregate, our comparable store sales gains continue to be driven by increases in average ticket values and robust professional ticket count growth. The growth in average ticket was primarily the result of same-sku inflation, which totaled 5.5% for our consolidated business and was in line with our expectations. Average ticket strength was the primary contributor to our low single-digit DIY comparable store sales increase in the second quarter. This benefit was partially offset by pressure to transaction counts, which were down low single digits and slightly below our expectations, in part due to headwinds in hot weather-related categories. Despite this pressure, we believe we're outperforming the market and gaining DIY share, and we continue to see tremendous growth opportunity on this side of our business. We also continue to be pleased with the robust sales growth we are generating with our professional customers.
Comparable store sales on this side of our business grew right at 10% in the second quarter, reflecting our fourth consecutive quarter of double-digit comps. The sales growth was fairly evenly split between an increase in average ticket value that was in line with our expectations and robust ticket count growth, which again outpaced our forecast. We don't quantify the individual ticket and traffic components of our sales results on a quarterly basis. However, I will share that our professional ticket count growth was in the mid-single digits in the second quarter and has essentially been within that range every quarter since our business normalized coming out of the pandemic. We are very excited about the continued momentum in our professional business and our team's ability to compound the market share gains they are winning quarter after quarter, year after year with our professional customers.
Next, I want to provide some detail on the cadence of our sales results as we move through the quarter. As I previously mentioned, our second quarter results surpassed our expectations, and we outpaced these projections each month of the quarter, with April's results outperforming a little more than May and June. As we discussed on last quarter's call, favorable spring weather supported by strong volumes in both our DIY and professional businesses as we exited the first quarter, and we saw much of that momentum continue in April. As we moved into our summer selling season, our sales trends moderated to a very consistent week-to-week pace through the remainder of the quarter. Finishing out the quarter, our June sales were solid on a one-year basis against a softer comparison in June of 2025.
We didn't realize the normal ramp-up in demand for certain hot weather-related categories that we typically like to see from the onset of summer heat at the end of the second quarter. We have definitely seen summer take hold across our markets in July, though, and we are very pleased with the strong step-up in sales results to start the third quarter. Turning to our revised full-year guidance, I want to provide some color on the update to our expected comparable store sales range. As noted in yesterday's press release, we have increased from the previous range of 3%-5% to a range of 4%-6%. This update flows through the outperformance we delivered in the first half of 2026 but leaves our expectations for comparable store sales growth for the back half of the year unchanged.
Looking forward, we are pleased with the strong start to the third quarter, but we're cognizant of the potential that the benefits we have realized so far this quarter are the result of normal month-to-month weather volatility, and we don't want to overreact to trends that could moderate over time. Included in our outlook for the remainder of the year is our expectation for the same SKU benefit to moderate in the third and fourth quarters as we calendar the tailwind from tariff-driven price increases that we realized in 2025. As a reminder, those benefits started to flow into our comp results as we moved through the third quarter last year, with the lion's share of the impact reflected in price levels by the time we exited the third quarter.
As a result of this dynamic, we are projecting the inflation benefit to moderate to 1%-2% for the back half of 2026, with the third quarter expected at the top end and continued moderation to the bottom end of that range by the fourth quarter. These assumptions reflect our standard approach for setting guidance. We assume only modest levels of prospective future price changes. While we've passed along some incremental price increases in 2026, resulting primarily from the cost pressures due to the increased crude oil prices, we are cautious as to how long these benefits will persist through the balance of the year. We are also cautious concerning the potential adverse impact to consumers and their resulting response in the face of continued economic pressure.
We have some very relevant recent experience that points to the potential for choppiness in consumer demand in the face of volatility in price levels. However, we have been pleased with the resiliency of the consumer and believe our customers have adjusted well to the current economic conditions and will continue to prioritize the maintenance and repair of their existing vehicles. Ultimately, we remain optimistic about the health of our industry, and our teams are committed as ever to build on our strong sales momentum. We believe it's prudent to incorporate into our updated guidance expectations some potential volatility as we finish out 2026. Before I move on from our guidance, I would also like to note that we are increasing our full-year diluted earnings per share guidance to a range of $3.20-$3.30.
Our increase in EPS guidance is driven by our sales and operating performance in the first half of 2026 and the impact of shares repurchased through the date of our earnings release yesterday. Before I wrap up my prepared comments and turn the call over to Brent, I'd like to spend a few minutes discussing our strategic priorities for use of capital and how these priorities align with the growth opportunities we see for our business. We are off to a strong start in 2026, and we remain extremely excited about our opportunities to build on this momentum, to drive continued growth, and to capture a larger share of the fragmented addressable market in our industry. We have refined our strategy to capitalize on this tremendous opportunity over many years, building and strengthening a world-class customer service organization and executing a sustainable growth plan.
Our capital allocation priorities directly align with that consistent long-term strategy. Our top priorities for use of capital continue to be reinvestments in our existing store and distribution network and organic growth through new store openings. We are currently 6,695 stores strong across North America, and Team O’Reilly includes over 95,000 of the most technically competent and customer-focused professional parts people in our industry. Our greatest opportunity to grow our business is to match the hard work and dedication of these team members with attractive stores, robust inventory availability, and enhanced technology. Our teams operate with a continuous improvement mindset, and we have been pleased with the returns on targeted investments in our existing business, which have helped fuel industry-leading comparable store sales growth.
We have also been pleased with the continued success of our organic store growth and remain excited about opportunity to further consolidate the industry through the opening of stores in both new geographies and existing market areas. The success of our organic growth strategy is the result of our commitment to never compromise on our proven model. For each new store we open, we aggressively identify and develop a knowledgeable and enthusiastic team of professional parts people to provide unsurpassed customer service from day one, supported by the very best inventory availability and selling tools in the industry. Over the course of our history, we have supplemented our capital investments in our existing network in our organic store growth with targeted opportunistic acquisitions.
Thanks, Brad. I would also like to join Brad in congratulating Team O’Reilly on a strong performance in the second quarter, driven by their steadfast dedication to our customers. I would like to begin my comments this morning by discussing our second quarter gross margin results and our outlook for the remainder of 2026. For the second quarter, our gross margin of 51.4% was unchanged from the second quarter of 2025. In establishing our gross margin outlook, we assumed a slightly lower gross margin rate in the second quarter as compared to the full year, which is typical for the seasonal composition of our product mix. While our gross margin rate for the second quarter came in slightly below our full-year guidance range, our results were in line with our expectations for the quarter.
We continue to see very stable, solid gross margin performance with only a few minor puts and takes driving the outcome for the quarter. We continue to benefit from incremental acquisition cost reductions and improved leverage of distribution cost on our strong top-line sales performance. On a year-over-year basis, these benefits were offset by mixed pressures from the faster rate of professional sales growth and our product mix in the quarter. We also faced our most challenging quarterly comparison in 2026 related to the timing benefit that we realized in the second quarter of 2025 from the impact of tariff-related cost and pricing adjustments. Given our in-line first half performance and the current stable market environment, we’re maintaining our full-year gross margin guidance range of 51.5%-52%. At the midpoint, this reflects an expansion of 16 basis points compared to 2025.
Through the first half of 2026, we are on track with our full-year target with our year-to-date gross margin rate of 51.5%, representing an 11 basis point expansion over the prior year. We are pleased to be able to continue to deliver incremental margin expansion while at the same time generating the robust gross profit dollar increases that come with our market-leading professional sales growth. Our experienced merchandise and supply chain teams continue to successfully partner with our supplier network to drive value for our customers and deliver these great results, while also proactively managing through any disruptions to global supply chains. Moving to SG&A. Our second quarter SG&A per store grew at 4.8%, which included incremental spend to support elevated sales volumes, similar to what we saw in the first quarter. We also experienced some modest incremental pressure from higher fuel prices.
We continue to be pleased with our team’s effectiveness in driving productivity through the management of our operating structure and our spend in the second quarter and first half of 2026 was within the range of our expectations. As we outlined coming into 2026, we anticipated growth in SG&A per store to be higher in the first half of the year, driven in part by expected year-over-year SG&A pressures from self-insurance and legal line items that ramped in the second half of 2025. Our experience for the first six months of 2026 for those line items has been in line with our expectations. While we saw modest pressure to our SG&A as a percent of sales, deleveraging 9 basis points in the second quarter, we outperformed versus our expectations as a result of the strong sales growth generated by our team.
We continue to expect our full year SG&A per store growth to be at or below 4%, but we are making a slight revision to tighten our full year range to 3.5%-4%, which incorporates the flow-through of our results for the first half of 2026. This reflects an expected moderation of per store operating expense in the back half of the year as comparisons ease, which is unchanged from our prior guidance. We are also reiterating our full year operating profit guidance range of 19.3%-19.8%, which reflects the sales, gross margin, and operating expense forecast that we have outlined today. For the first half of 2026, our operating margin expanded 21 basis points, split evenly between gross margin expansion and SG&A leverage, and driving an increase in operating profit dollars of 10%.
We strongly believe that our greatest long-term strategic opportunity is our ability to leverage our industry-leading business model and execution to provide the best customer service in our industry. Our company operates in a fragmented industry and still holds a small percentage of the total addressable market. We have demonstrated that we are willing to aggressively lean into the investments and initiatives that equip us to address this opportunity, and we are very pleased to deliver productive returns on those efforts so far in 2026. Before I turn the call over to Jeremy, I want to provide an update on our store growth and capital investments for the first half of 2026 and our outlook for the remainder of the year.
Year-to-date, we have opened 110 net new stores, with that growth spread across 31 U.S. states, Puerto Rico, Mexico, and Canada. We remain on track to open 225-235 net new stores in 2026. Capital expenditures in the first six months of 2026 were $552 million. We still expect a total capital expenditure investment for 2026 of $1.3 billion-$1.4 billion. Our planned expenditures in 2026 mirror the capital allocation priorities that Brad outlined earlier, including acceleration in new store growth, corresponding enhancement of our distribution capabilities to support our industry-leading inventory availability, and targeted initiatives to maintain and refresh the image and appearance of our store fleet and enhance our technology tools. We continue to pair these capital investments in our existing business with targeted investments in inventory.
Inventory per store finished the second quarter at $892,000, which was up 7% from this time last year and up 2% from the end of 2025. This growth is slightly below what we originally projected for the first half of the year as a result of normal seasonal timing differences in the deployment of inventory. However, we are still targeting growth of 5% per store by the end of 2026. We are excited to be able to highlight the tangible impact of these investments when we host our upcoming Analyst Day at our new Atlanta distribution center on September the 17th. We relocated our previous DC in Atlanta to this new 690,000 sq ft facility at the end of 2024. The incremental distribution capacity provided by this DC is enabling us to unlock additional expansion in the southeastern U.S. and support import processing capabilities.
This new facility is a great illustration of our proven business model and the continuous improvements we make to refine the processes and technology in our buildings to relentlessly enhance inventory availability and the value proposition that we offer our customers. As I close my comments, I want to once again thank Team O’Reilly for their commitment to providing excellent, consistent customer service to all our customers each and every day. I'll turn the call over to Jeremy.
Thanks, Brent. I would also like to thank all of Team O’Reilly for another strong quarter. We will fill in some additional details on our second quarter results and outlook for the remainder of 2026. For the second quarter, sales increased to $367 million, driven by a 6% increase in comparable store sales and a $100 million non-comp contribution from stores opened in 2025 and 2026 that have not yet entered the comp base. For 2026, we now expect our total revenues to be between $18.9 billion and $19.2 billion. Our second quarter effective tax rate was in line with our expectations at 22.6% of pre-tax income, comprised of a base rate of 23.3%, reduced by a 0.7% benefit for share-based compensation.
This compares to the second quarter of 2025 rate of 22.4% of pre-tax income, which was comprised of a base tax rate of 23.2%, reduced by a 0.8% benefit for share-based compensation. For the full year of 2026, we now expect an effective tax rate of 22.5%. We expect the quarterly rate to fluctuate due to variations in the tax benefit from share-based compensation and the totaling of certain tax periods in the fourth quarter. We will move on to free cash flow and the components that drove our results. Free cash flow for the first six months of 2026 was $1.5 billion, versus $904 million in the first half of 2025.
The increase in free cash flow was primarily driven by robust growth in operating income and the timing of payment for renewable energy credits, with a higher cash outflow for these payments occurring in the second quarter of 2025. For the full year of 2026, our expected free cash flow guidance remains unchanged at a range of $1.8 billion-$2.1 billion. I also want to touch briefly on our AP to inventory ratio. We finished the second quarter at 124%, which was in line with the same level at the end of 2025. For 2026, we expect to see continued moderation resulting from our planned incremental inventory investment and expect to finish the year at a ratio of approximately 122%. Moving on to debt.
We finished the second quarter with an adjusted debt to EBITDAR ratio of 2.17x, which was an increase from our ratio at the end of 2025 of 2.03x. This incremental step-up in leverage reflects additional borrowings through our commercial paper program and is consistent with our intention to prudently approach our optimal leverage target of 2.5x. We continue to be pleased with the execution of our share repurchase program, and during the second quarter, we repurchased 17 million shares at an average share price of $90.40 for a total investment of $1.5 billion. Our 2026 year-to-date share repurchases through the date of yesterday's press release totaled 34 million shares for a total investment of $3.1 billion.
We have consistently viewed our buyback program as an effective means of returning excess capital to our shareholders, and the step-up in share repurchase volume in 2026 reflects our strong cash flow generation and incremental borrowings as we move towards our leverage target. As Brad discussed earlier, we are very excited about the opportunities we have to execute our strategic roadmap, and we will continue to prioritize capital investments in our existing business to grow market share. When it is appropriate to return excess capital to shareholders, we are very confident that the average repurchase price is supported by the expected discounted future cash flows of our business. Before I open up the call to your questions, I would like to thank our team for their commitment to the excellent customer service that drives our success. This concludes our prepared comments.
At this time, I would like to ask Matthew, the operator, to return to the line and we will be happy to answer your questions.
