AutoZone (AZO) Q4 2025 earnings review
Commercial Sales Boom Masked by Crushing LIFO Charge; Margin Pressure to Intensify
AutoZone reported strong top-line momentum in Q4, with adjusted sales growing 6.9% and the crucial Domestic Commercial segment accelerating for the fourth consecutive quarter to +12.5% growth. However, this impressive sales performance was completely overshadowed by a massive $80 million non-cash LIFO charge, reflecting rising inventory costs from tariffs. This accounting charge wiped out underlying profit growth, resulting in a mere 1.3% increase in adjusted EPS. The outlook suggests more pain ahead, with management guiding for an even larger $120 million LIFO charge in Q1 2026, signaling that significant margin compression will continue despite the robust sales environment.
🐂 Bull Case
The Domestic Commercial business is showing powerful, accelerating growth, reaching 12.5% in Q4. This validates the company's strategy of investing in Hub stores and parts availability, proving it can consistently take share in the professional market.
Management is signaling strong confidence with plans to open 325-350 stores in FY26, the most since 1996, and invest ~$1.5 billion in CapEx. This positions the company to capture long-term growth in both domestic and international markets.
🐻 Bear Case
The $80 million Q4 LIFO charge is a major red flag for earnings quality. The guidance for this charge to swell to $120 million in Q1'26 suggests cost pressures are intensifying, which will severely depress reported earnings for the foreseeable future.
Beyond LIFO, the company is purposefully deleveraging SG&A to fund its growth initiatives. While strategic, this, combined with a mix shift to the lower-margin commercial business, puts significant pressure on operating margins.
⚖️ Verdict: 🔴
Bearish. While the accelerating commercial sales are impressive, the story is overshadowed by poor earnings quality. The massive and growing LIFO charge indicates severe cost inflation that is not being fully passed through, destroying reported profits. Until there is a clear path to managing these costs without sacrificing more margin, the strong top-line performance is a hollow victory.
Key Themes
LIFO Charge Snowballs, Signaling Intensifying Cost Pressure
The most critical takeaway is the severe and growing impact of the LIFO accounting charge, which reflects rapidly rising inventory costs, primarily due to tariffs. After booking an $80 million charge in Q4, management guided for a staggering $120 million charge in Q1'26, followed by $80-$85 million per quarter thereafter. This sequential increase contradicts the positive sales narrative by highlighting that underlying cost inflation is accelerating faster than the company can offset it, creating a direct and material headwind for reported EPS for at least the next year.
Commercial Business Reaches 'Escape Velocity'
The Domestic Commercial business has been the undeniable star, with YoY growth accelerating for four straight quarters: 3.2% -> 7.3% -> 10.7% -> 12.5%. This trend confirms the success of strategic investments in parts availability via Hub and Mega Hub stores and improved delivery speed. The company is successfully capturing share in the professional market, providing a powerful and consistent engine for top-line growth that is offsetting softness in the DIY segment.
Aggressive Expansion Plan Signals Long-Term Confidence
Management announced plans to open 325-350 new stores in FY26, the most in a single year since 1996. This aggressive physical footprint expansion, supported by a planned $1.5 billion in capital expenditures, signals strong conviction in the long-term growth opportunities in both domestic commercial fulfillment and international markets like Mexico and Brazil.
Inventory Growth Outpaces Sales
Total merchandise inventory grew 14.1% YoY, more than double the adjusted sales growth of 6.9%. While management attributes this build to supporting growth initiatives like new stores and hubs, such a significant divergence represents a risk. It ties up cash and could lead to future margin pressure from discounting or write-offs if the expected sales fail to materialize at the same pace.
Pricing Power Tested as Tariffs Bite
Management expects cost inflation to be at least 3% for the rest of the calendar year, largely driven by tariffs. The massive LIFO charges confirm these costs are real and hitting the supply chain now. While the industry is historically rational on pricing, the ability to pass these costs on fully to a pressured consumer remains a key question. The current strategy appears to be absorbing a portion of the hit, directly impacting profitability.
Discretionary Spending Shows 'Green Shoots'
A potential bright spot emerged as management noted that discretionary categories, a persistent drag on the DIY business, grew at a pace 'not seen since FY 2023.' While acknowledging the lower-end consumer is still pressured, this could be an early indicator that the worst of the DIY spending slump has bottomed out, providing a potential tailwind heading into FY26.
Other KPIs
Decelerating. Margin fell 98 basis points YoY. This was entirely due to a 128 basis point negative impact from the non-cash LIFO charge. Excluding this accounting impact, underlying merchandise margins actually improved by approximately 25 basis points, indicating strong core pricing and sourcing discipline that is being masked by inflationary headwinds.
Accelerating. CapEx increased 27% from $1.07 billion in FY24. This reflects the company's aggressive investment cycle focused on building out its network of Hub and Mega Hub stores, opening two new distribution centers, and expanding its international footprint. A similar level of investment (~$1.5B) is planned for FY26.
Stable. The international segment continues to be a reliable growth driver, posting strong results in Mexico and Brazil. However, reported results were negatively impacted by a 510 basis point currency headwind from a stronger US dollar, a factor that is expected to shift to a tailwind in Q1'26.
Guidance
Reversing/Negative. This is a significant negative surprise, representing a 50% increase from the Q4 charge of $80M. It implies a substantial headwind to Q1'26 gross margins and reported EPS, suggesting cost inflation from tariffs is accelerating into the new fiscal year.
Accelerating. This implies a significant ramp-up from the 304 net new stores opened in FY25. The growth will be skewed to the back half of the year and will drive continued SG&A investment.
Reversing. After being a persistent headwind throughout FY25, currency translation is expected to become a tailwind in Q1'26, providing a modest boost to reported earnings. This is driven by movements in the Mexican Peso relative to the US Dollar.
