O'Reilly Automotive, Inc. (ORLY) got a fresh Buy endorsement from Bank of America on Monday, as the brokerage reinstated coverage on the automotive aftermarket specialty retailer.

Analyst Christopher Nardone slapped a Buy rating and a $106 price target on the stock, which implies about 17.9% upside from the reference share price of $89.92. Not a bad day at the office if you own the shares.

So why the love? Nardone pointed to strong execution, resilient comparable store sales growth, a favorable revenue mix, and a sophisticated distribution network. Those are the ingredients he says justify the company's premium valuation among its peers.

The next big moment for the company arrives Oct. 28, when it reports third-quarter earnings. Mark your calendars.

The Professional Business Is the Star of the Show

Bank of America made it clear that O'Reilly's commercial business is a major growth engine. Professional customer sales reached $8.6 billion in 2025 and represented 50.5% of total revenue in the second quarter. That was a 12.5% increase year over year and marked the fourth consecutive quarter of double-digit comparable sales growth.

Here's the kicker: Nardone estimates O'Reilly holds less than 10% of the professional automotive aftermarket. That means there's a whole lot of runway left for the company to penetrate further and grab share.

Bank of America also expects industry dynamics to tilt in favor of the professional market as parts and repair requirements grow more complex and DIY appetite declines. In other words, fewer people are wrenching on their own cars, and more are paying professionals to do it. That's a tailwind for O'Reilly.

The firm flagged the company's smaller DIY revenue mix as an advantage, since DIY is more exposed to inflation and higher gasoline prices, which can pressure consumer spending over the long term. Less exposure to the fickle consumer wallet is a good thing right now.

And then there's the distribution muscle. Nardone cited the company's infrastructure of over 32 regional distribution centers and more than 400 hub stores as a key competitive advantage. That's the kind of logistical backbone that's hard to replicate.

Store Growth and Cost Controls Keep the Earnings Train Rolling

O'Reilly is targeting 225 to 235 net new stores in 2026, compared with 207 in 2025. Bank of America expects selling, general and administrative expenses to remain elevated, but it anticipates expense growth per store to moderate. Specifically, growth is expected to slow to approximately 3% in the second half of 2026 from 5% in the first half.

Nardone noted that O'Reilly remains focused on smaller tuck-in acquisitions in expansion markets, with no plans to pursue a large-scale, transformative acquisition in the near to medium term. Slow and steady wins the race, apparently.

A Premium Valuation Backed by a Strong Growth Outlook

Bank of America expects O'Reilly to deliver 4% to 5% comparable store sales growth through 2028, supported by market share gains, demand from professional businesses, and potentially higher auto parts inflation.

O'Reilly itself expects comparable store sales growth of 4% to 6% while forecasting same-SKU inflation to moderate from 5.5% to 1% to 2% in the second half of 2026. Bank of America believes those projections could prove conservative as industry expectations for same-SKU inflation increase.

Speaking of which, Advance Auto Parts Inc. (AAP) and AutoZone, Inc. (AZO) recently increased their expectations for same-SKU inflation by roughly 100 basis points. That's a signal that pricing power is alive and well in the aftermarket.

The company has continued to generate strong free cash flow despite doubling its capital expenditure since fiscal 2022 as it invests in its distribution network and store growth. Management expects fiscal 2026 free cash flow of $1.8 billion to $2.1 billion, with capital expenditures of $1.3 billion to $1.4 billion.

Bank of America expects the company to keep taking share in a highly fragmented market and enter a sustained positive earnings-per-share revision cycle. Nardone forecasts earnings per share of $3.27 in 2026 (up 10.1%), $3.64 in 2027 (up 11.3%), and $4.05 in 2028 (up 11.3%). That's double-digit annual growth, folks.

The $106 price forecast is based on 29 times estimated 2027 earnings, a premium to consumer companies with similar growth. Premium valuation for a premium business, or so the thinking goes.
