ADVANCE AUTO PARTS INC (AAP) stock intrinsic value fair value estimate & owner earnings analysis

Advance Auto Parts sells replacement parts and accessories to do-it-yourself customers and professional installers across roughly 4,300 company stores plus about 800 independently owned Carquest locations. In 2025 the company sold Worldpac, its import/OEM parts distribution business, for roughly $1.5 billion in cash, refocusing the company on its core Advance Auto Parts and Carquest retail and professional-installer business. Because that sale changes what the company actually is, this valuation is built entirely on the results of the business as it exists today -- retail and professional parts distribution only -- and does not lean on the years before the sale, when Worldpac's results were mixed in. The last few years have been difficult. Comparable-store sales underperformed for an extended period, culminating in a board-approved restructuring plan in November 2024 that closed about 500 company stores, 200 independently owned locations, and four distribution centers -- essentially completed by the first quarter of 2025. That program cost roughly $680 million in 2024 and a further $159 million in 2025, and it drove a large net loss in 2024. The good news: with the closures behind it, gross margin recovered by nearly 6 percentage points in 2025 as the one-time inventory write-down charges from the closures rolled off, and sales at the stores that remain open turned modestly positive (+0.8%) for the first time in years. Net income for the ongoing business was back to positive territory in 2025 ($68 million), though the business as a whole still ran a small operating loss for the year. We measure what the business actually generates for owners -- operating cash flow after removing the swings caused by inventory and payables timing, stock-based compensation, and the portion of capital spending that goes toward growth rather than just keeping the existing stores running. On that basis, the last four years -- the only years we can cleanly measure on the current, post-Worldpac basis -- look like this: roughly $4.04 per share in 2022 (before the trouble was fully visible), essentially breakeven in 2023, a deeply negative reading of about -$8.06 per share in 2024 (the trough of the restructuring program), and a recovery to about $2.44 per share in 2025. Taking the middle of that range as a normalized starting point -- deliberately not the best year and not the worst -- puts underlying earning power at roughly $1.06 per share today, a conservative starting point given that the most recent full year already came in well above it and the first half of the newest fiscal year shows profit continuing to run ahead of last year's pace on essentially flat sales. One thing worth flagging plainly: in 2025 the company roughly doubled its debt load, from $1.8 billion to $3.45 billion, issuing $1.95 billion of new bonds at 7.0% and 7.375% interest -- noticeably higher rates than its older debt, a sign that lenders are charging more for the added risk. That new debt, combined with the Worldpac sale proceeds, left the company with a large cash balance (over $3 billion), but it also means a meaningfully higher permanent interest bill going forward. The filings also note that some suppliers' willingness to extend the company favorable payment terms depends on its credit standing -- a lever that could tighten further if the credit picture doesn't keep improving. Putting this together into three cases: The bear case assumes the competitive pressure from larger, better-capitalized rivals continues to erode sales gradually, margin recovery stalls short of where it stood before the crisis, and the heavier interest burden keeps consuming a large share of cash generated for years to come, with per-share owner earnings recovering only slowly from a low starting point and never compounding meaningfully. That points to a value of roughly $12 per share. The base case assumes the restructuring is genuinely done -- not just paused -- and that the margin recovery and positive comparable sales already visible in 2025 and continuing into 2026 hold, letting per-share earning power settle back near last year's actual level and grow slowly and modestly from there as a smaller, more productive store base matures. That points to a value of roughly $39 per share. The bull case assumes the rationalized store network delivers what it was designed to deliver -- continued positive comparable sales, gross margin recovering further toward where it stood before the crisis, and the large cash balance eventually used to pay down the expensive new debt -- pushing per-share earning power back toward its pre-crisis range. That points to a value of roughly $62 per share. Given the business is still only one year removed from its lowest point, carries meaningfully more debt than it did two years ago, and has a multi-year track record of underperforming better-capitalized competitors before this turnaround began, the margin-of-safety price sits at a substantial discount to our estimate of fair value, and assumes the early signs of recovery -- positive comparable sales and continued margin improvement -- hold for a couple more quarters before the turnaround is treated as durable rather than a rebound from an unusually depressed base. One item we could not fully reconcile from the numbers alone: the swing from a $400 million working-capital cash inflow in 2024 (mostly from liquidating inventory tied to closed stores) to a $482 million working-capital cash outflow in 2025 (mostly from paying down payables) is large and worth watching, though the filings' own explanation -- normalization after the closure program plus a reduction in supplier payment terms -- is a reasonable one.
