Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Net sales increased 5.9% year-over-year. This growth was driven by an additional 53rd week of sales ($365.9 million), new store openings ($292.4 million), and a 1.4% increase in total company same-store sales on a constant currency basis.
• Profitability: Operating profit rose 9.1% to $3.79 billion. Gross margin expanded 114 basis points to 53.1%, aided by higher merchandise margins and a $84.0 million non-cash LIFO benefit.
• Expense Pressure: Operating, selling, general, and administrative (OSG&A) expenses increased to $6.03 billion (32.6% of sales) from $5.60 billion (32.1% of sales), primarily due to increased domestic store payroll costs.
• Interest Expense: Net interest expense increased significantly to $451.6 million from $306.4 million, reflecting higher average borrowings ($8.7 billion vs. $7.0 billion) and higher weighted average borrowing rates (4.39% vs. 3.78%).
• Store Count: The company added 213 net new stores during the fiscal year, bringing the total to 7,353.

Guidance, Outlook, and Risks

Management Commentary & Outlook:

• Management expects to increase investment in the business in fiscal 2025, focusing on supply chain initiatives, new distribution centers, and expanded hub/mega hub stores.
• The company continues to prioritize share repurchases, with $2.0 billion remaining under authorization as of October 21, 2024.
• Key market drivers cited include miles driven (up 1.2% YTD) and the aging vehicle population (average age 12.6 years).

• Macroeconomic Factors: Inflation, high interest rates, consumer debt levels, and fuel prices could reduce discretionary spending and vehicle maintenance demand.
• Supply Chain: Disruptions in global supply chains, port congestion, and raw material costs remain risks.
• Technology & EVs: The increasing prevalence of electric vehicles (EVs) and technological advances in vehicle durability could reduce the frequency of parts failures and maintenance needs.
• Self-Insurance: The company is self-insured for significant portions of workers' compensation, general liability, and other risks. A 10% change in self-insurance liability estimates would impact net income by approximately $18.8 million.
• Cybersecurity: Risks related to data privacy, cyber-attacks, and system interruptions are highlighted as material threats.

• 53rd Week: Fiscal 2024 included a 53rd week, contributing $365.9 million in sales and $60.7 million in net income. Excluding this week, same-store sales growth was 0.4% domestically and 10.2% internationally (constant currency).

Investor Verification Checklist

• Debt Servicing: Verify the sustainability of the increased interest expense ($451.6M) against operating cash flow given the rising interest rate environment.
• Same-Store Sales Trend: Monitor the deceleration in domestic same-store sales growth (0.4% in FY24 vs. 3.4% in FY23) to assess consumer demand resilience.
• Capital Allocation: Confirm the pace of share repurchases relative to the $2.0 billion remaining authorization and the company's target debt-to-EBITDAR ratio (currently 2.5x).
• EV Impact: Evaluate management's specific strategies to mitigate the long-term risk of electric vehicles reducing the aftermarket parts replacement cycle.
• Self-Insurance Reserves: Review the actuarial assumptions for self-insurance reserves ($257.7 million) given the sensitivity of net income to changes in these estimates.
