U.S. Auto Parts Chain Soars 6% on Earnings Boost

O’Reilly Automotive (ORLY) closed at $97 on the Nasdaq on the 29th, up 5.93% from the previous day, lifting its market capitalization to approximately $81.1 billion. Trading volume exceeded 4.26 million shares, and in a single session its market cap swelled by about $5.1 billion (over KRW 7 trillion), instantly reversing its earlier sluggish stock performance.

In its Q1 2026 earnings release, the company reported record quarterly revenue and profits, with sales reaching roughly $4.56 billion, reigniting investor enthusiasm. Strong results across the sector and the confirmation of 33 consecutive years of same-store sales growth have fueled expectations that its valuation premium will remain intact in the near term.

O’Reilly Automotive operates more than 6,000 stores across the U.S., Mexico and Canada, making it a leading North American auto-parts distribution chain serving both DIY customers and professional repair shops. Since its Nasdaq listing in 1993, it has been regarded as a growth stock, backed by aggressive store expansion, share repurchases and shareholder-friendly initiatives—including a 15-for-1 stock split in 2025.
