SONIC AUTOMOTIVE INC (SAH) stock intrinsic value fair value estimate & owner earnings analysis

Sonic Automotive is one of the largest auto retailers in the United States. It runs three businesses: about 110 franchised new-vehicle dealerships, mostly luxury and import brands such as BMW, Mercedes-Benz, Honda, Toyota and, since 2025, five Jaguar Land Rover stores in Southern California (roughly 85% of revenue); the EchoPark used-vehicle stores, cut back to 18 locations after an over-expansion that lost $132.5 million at the segment level in 2023 but earned $28.1 million in 2025; and a small powersports segment. New-car sales swing with the economy, but much of the profit comes from parts, service and finance-and-insurance income attached to every car sold and serviced. Fixed operations (parts and service) gross profit grew 15% in 2025 (13% at same stores). State dealer franchise laws make these franchises hard to take away, which is why we treat the store base as a lasting business. How we measure earnings. We start from operating cash flow, remove swings in working capital, subtract stock compensation as a real cost, and subtract the share of capital spending needed to keep existing stores running (spending that only matches revenue growth is treated as optional). Floor-plan financing, the loans that fund the inventory on the lots, is treated as a normal operating cost of a car dealer: its interest stays inside earnings and the floor-plan loans are not counted as debt. The company's other borrowing (senior notes, real-estate mortgages, finance leases) is handled separately: we add back its interest to get what the business earns before those lenders, value that, and then subtract the debt. The filings do not split cash interest paid between floor-plan and other debt, so we use the reported non-floor-plan interest expense for that add-back. On that basis the business generated roughly $255 million to $396 million a year before non-inventory interest over 2021-2025. We use the median of 2021-2025, about $268 million (around $8.35 per current share), because 2021 is when the RFJ acquisition gave Sonic its present scale, and the window spans both the vehicle-shortage boom of 2021-2022 and the normalization of 2023-2024. Large non-cash write-downs ($320 million in 2022, $79 million in 2023, $174 million in 2025, mostly franchise rights) are added back because they write off past purchase prices rather than consume cash. But a habit of overpaying for stores is a real risk, and we charge for it in the bear case. What changed since our previous analysis. We previously treated the jump in 2025 earnings as mostly accounting. On closer review, the working-capital swing is already stripped out, and 2025 earnings were genuinely strong: segment income rose to $346.5 million from $260.0 million, helped by the Jaguar Land Rover acquisition, an EchoPark profit and lower capital spending. Results for the first half of 2026 (net income of $118 million, on revenue up about 4%) are good but running below the 2025 pace once 2025's write-down is set aside, so we have not used 2025 as the earnings level. In 2025 the business's cash earnings before non-inventory interest grew about 56%; our base case assumes 2% in year one, well below that. Previous per-share figures are not fully comparable because this analysis values the business before its lenders and then subtracts the debt. Debt. At June 30, 2026 Sonic owed about $1.76 billion in non-inventory debt: $650 million of 4.625% notes due 2029, $500 million of 4.875% notes due 2031, a real-estate mortgage facility (about $456 million at year-end 2025) and smaller mortgages, plus about $380 million of finance leases. Cash was only $19 million. The two note issues carry fixed rates below today's borrowing costs, which is worth about $48 million to shareholders until they mature. Net debt is therefore taken at about $2.07 billion, roughly $65 per share. Debt has risen in 2026 while the company bought back $142 million of stock in the first half. Base case. Earnings start at $268 million and grow 2% a year for ten years, reflecting the long record of parts, service and labor prices rising with inflation. We give no credit to future acquisitions, more EchoPark stores or margin gains, because those depend on deals and execution that have not happened yet. After year ten earnings hold flat, supported by the protected franchise base. The business is worth about $5.2 billion; less $2.07 billion of debt, that leaves about $3.15 billion, or roughly $98 per share. Bear case. Auto retail has a real record of severe downturns. In 2008-2009, U.S. new-vehicle sales fell about 40% and Sonic's own finances came close to breaking, with its share price briefly near $1. We assume a downturn of that kind in years three and four (2028-2029) that cuts earnings before non-inventory interest roughly in half, to about $130 million, while parts and service hold up. Earnings then recover to only about $230 million, below today's level, reflecting continued overpaying for acquisitions and write-downs. The downturn coincides with the 2029 note maturity, so we assume the $650 million is refinanced at about 4 percentage points more, costing about $114 million in today's money. Trough earnings still cover the roughly $110 million non-inventory interest bill, though only narrowly. The business is worth about $3.64 billion against about $2.19 billion of debt and refinancing cost, roughly $45 per share. Bull case. Earnings start at $320 million, between the anchor and the 2025 result, recognizing the Jaguar Land Rover stores and a profitable EchoPark. They grow 3% a year as parts and service keep compounding at the pace of recent years, then hold flat after year ten. The business is worth about $6.7 billion; less $2.07 billion of debt, roughly $146 per share. Margin-of-safety price. We are reasonably confident in the earnings level: in each of the last seven years the business produced positive cash earnings, and in the last five they ranged between about $255 million and $396 million before non-inventory interest. We are less confident in its stability. The worst plausible outcome is a deep sales downturn arriving as the 2029 notes come due, at a time when Sonic carries more debt and almost no cash because it has been borrowing to buy back stock. Its owned real estate (pledged under the mortgage facility) and franchises protected by state law make survival likely, but shareholders could face several lean years. The founding Smith family controls the company through high-vote Class B shares, so outside shareholders have no say over capital allocation. That record has been mixed: the EchoPark over-expansion and repeated franchise write-downs alongside sensible buybacks. If we are wrong and earnings settle near $220 million with no growth, the shares are worth about $50. If the level holds but nothing grows, about $75. Our bear case is $45. During the holding period the company pays a quarterly dividend and its share count keeps falling. At $48 the shares sit close to our bear value and to the value with no growth at a lower earnings level. If the business simply delivers its base case over four years, that case implies a return including dividends above 20% a year. Above about $50 the price would depend on the base case arriving faster than a cyclical business can promise.
