AutoZone reported net sales of $4.27 billion for the 12 weeks ended Feb. 14, up 8.1% year-over-year but falling short of analysts' expectations. FactSet had forecast sales of $4.31 billion, meaning the company missed estimates by $40 million. The retailer attributed the shortfall to severe winter storms that disrupted operations and consumer traffic across key markets.

The sales miss comes despite AutoZone's typically strong performance during winter months, when harsh weather drives demand for car parts and maintenance. The company's comparable-store sales grew 6.9% during the period, indicating underlying demand remained healthy despite weather-related challenges. AutoZone operates over 6,000 stores across the United States, Mexico, and Brazil, making it particularly vulnerable to regional weather disruptions.

While the sales miss disappointed investors, AutoZone's overall growth trajectory remains positive. The company's ability to generate double-digit revenue growth during a challenging weather period demonstrates resilience in its business model. AutoZone shares have gained approximately 15% over the past year, outperforming many retail peers as consumers continue to hold onto vehicles longer, driving demand for replacement parts and maintenance services.
