Company Reports

O’Reilly Auto Parts’ strategy is anchored by its dual-market approach, successfully serving both do-it-yourself, or DIY, customers and commercial service providers—do-it-for-me, or DIFM. This balanced exposure, split almost evenly in terms of revenue composition, insulates the firm across economic cycles while providing a stable growth platform in a fragmented industry. The cornerstone of O’Reilly’s competitive positioning is its robust hub-and-spoke distribution network. Unlike mass merchants or pure e-commerce players that struggle with rapid fulfillment, O’Reilly’s infrastructure, which includes over 30 distribution centers, nearly 400 hub stores, and over 6,300 retail locations, positions inventory extremely close to the customer. This enables multiple daily deliveries to professional shops, where minimizing vehicle downtime is paramount and often supersedes price sensitivity. Consequently, we view its logistics network and technical expertise as formidable barriers to entry that protect its market share from digital disruption and yield consistent profitability, highlighted by operating margins that have remained around 20%.

O'Reilly's second-quarter results had a 6% comparable-store-sales increase and adjusted EPS of $0.86 (up 10.8%). Gross margin held at 51.4% as acquisition costs and distribution efficiencies offset professional mix pressure, while operating expenses rose by 9 basis points due to higher fuel prices.

Amid an aging US vehicle fleet and rising automotive complexity, O'Reilly operates roughly 6,600 stores across North America, supplying auto parts to do-it-yourself and commercial customers. Its nearly $18 billion in fiscal 2025 sales has been facilitated by a vast hub-and-spoke delivery network.

O'Reilly posted 10.2% top-line growth in the first quarter, underpinned by an 8.1% uptick in comparable sales and 59 new stores. Operating margin rose roughly 60 basis points from the prior year to 18.5%.

O'Reilly reported sales growth of 7.8% in the fourth quarter, underpinned by 5.6% comparable store sales growth and 47 new stores, putting 2025 net new openings at 207. Operating margin widened by about 70 basis points to 18.8%.

With over 6,000 stores across the United States, wide-moat O’Reilly Automotive boasts a resounding presence in the automotive aftermarket. The retailer greatly expanded its footprint in the do-it-yourself subset of the aftermarket via its acquisition of CSK in 2008, and we estimate the firm currently holds a low-double-digit percentage share of the DIY market, second only to wide-moat AutoZone. Despite facing copious competition from online channels and diversified retailers, O’Reilly’s value proposition is predicated in its knowledgeable staff and ample product availability. Contrary to most non-pure-play auto parts retailers, O’Reilly’s staff assists customers with vehicle diagnosis, the ordering of parts for a specific vehicle’s make and model, and testing the functionality of parts. Given auto repairs are often nondiscretionary and, in many instances, time sensitive, we surmise consumers value the level of expertise provided by O’Reilly’s staff. Furthermore, the firm’s hub-and-spoke supply chain model and favorable supplier relationships provide it with significant localized distribution capacity. As such, the firm is able to quickly distribute products across its local store base to meet time-sensitive consumer demand. We view the firm’s levels of customer service and convenience as difficult to replicate and valuable to customers, allowing O’Reilly to consistently deliver a gross margin above 50%.

Top-line growth continued to accelerate in O'Reilly's third quarter to 7.8%, underpinned by 5.6% comparable store sales growth and 46 new stores, putting year-to-date openings at more than 53% higher than a year ago. Operating margin widened by 50 basis points to 20.7%.

We plan to raise our $870 fair value estimate on wide-moat O’Reilly by a low- to- mid-single-digit percentage after the firm delivered strong fourth-quarter marks. Results featured a 4.4% increase in comparable sales, outpacing our 3% forecast and the 3.9% uptick in motor vehicle parts and accessories expenditures in the fourth quarter, per the Bureau of Economic Analysis. Encouragingly, the firm delivered a healthy combination of mid-single-digit comp growth in the professional channel and a 3% gain in sales to do-it-yourself customers. Regarding profitability, operating margin of 18.9% increased about 10 basis points from the prior year when adjusting for a self-insurance reserve charge, closely aligning with our 19% estimate.

Wide-moat O’Reilly Automotive's third-quarter results slightly underperformed our expectations. Comparable sales growth of 1.5% trailed our 2.5% forecast, and operating margin declined 80 basis points to 20.5% versus our 20.7% estimate. We expect a soft demand backdrop to persist through the remainder of the year and anticipate lowering our forecasts for 2024 comp growth to 2.5% from 3% and for operating margin to 19.7% from 19.9%. Nonetheless, we do not plan to materially change our $860 fair value estimate as we think O’Reilly’s competitive standing is intact.

Wide-moat O'Reilly's second-quarter results lagged our estimates, as comparable store sales growth of 2.3% landed below our forecast for a 4% gain, and operating margin of 20.2% represented an 80-basis-point decline. In light of a softer demand environment, management trimmed its top-line guidance for the full year to 2%-4% comp growth (from 3%-5% previously), but its operating margin target of about 20% remained largely intact. Despite underperforming expectations, the stock popped by a mid-single-digit percentage. We share in the market's positive sentiment because weak demand for aftermarket auto parts appears pervasive across the fragmented industry, and we think O'Reilly continues to gain market share, which should prove favorable longer term. For instance, O'Reilly's low-single-digit comp growth again outpaced its close competitor, narrow-moat Genuine Parts (owner of the NAPA brand), which reported a 1.5% decline in domestic automotive comp sales. We plan to raise our $810 fair value estimate by a low- to mid-single-digit percentage due to the time value of money and a slight upward adjustment to our long-term comp growth forecast.
