AppLovin Corp (APP) stock intrinsic value fair value estimate & owner earnings analysis

AppLovin runs a mobile advertising platform. Its Axon AI recommendation engine matches advertisers, chiefly mobile game and app developers, with app publishers that sell ad space through auctions, and AppLovin keeps the difference. Since 2024 it has also begun signing web-based e-commerce advertisers. On June 30, 2025 it sold its own mobile games portfolio (the Apps business) to Tripledot for $430.6 million in cash plus about 20% of Tripledot's equity, so what remains is a pure advertising software company. In 2025 revenue was $5.48 billion, up from $3.22 billion in 2024 and $1.84 billion in 2023 on a continuing basis, and net income from continuing operations was $3.43 billion, a 62.6% margin. In the first half of 2026 revenue rose 56% and net income rose to $2.47 billion from $1.40 billion. How we measure earnings. We start from operating cash flow, strip out swings in receivables, payables and other working capital, and deduct stock compensation as a real cost ($210 million in 2025) and maintenance capital spending, which is negligible (under $5 million a year). On that basis earnings per diluted share were $1.02 in 2019, $1.05 in 2020, $1.50 in 2021, $1.38 in 2022, $2.49 in 2023, $5.97 in 2024 and $10.77 in 2025. We anchor on the 2025 figure of $10.77. Earlier years describe a different business, one that owned a games portfolio and had not yet reached today's scale, so they are not a fair picture of what is being valued. Both quarters of 2026 reported so far ran above the 2025 pace, which supports treating 2025 as the current level rather than a peak; the base case does not lift the level on that evidence. In 2025 the company paid only $195 million in cash taxes against a $520 million tax charge; because we strip working-capital timing, our figure charges the full tax expense and takes no credit for that deferral. Equity pay costs more in cash than its expense line suggests: in 2025 the company paid $392 million in taxes withheld on employee share vesting, against $210 million of stock compensation expense, which is one reason we keep a wide margin of safety. Debt is not subtracted separately because interest is already paid out of cash flow. There are $3.6 billion of senior notes (5.125% due 2029, 5.375% due 2031, 5.5% due 2034 and 5.95% due 2054) against $2.5 billion of cash at year end 2025. Growth. Earnings per share grew 80% in 2025, from $5.97 to $10.77. Our base case assumes 0% growth in year 1 and afterward, below the trailing rate, because we cannot point to a contract or a long record that secures continued growth. Substantially all customer contracts can be cancelled at any time, and the strong results cover only 2023 through 2025, too short to count as a proven, repeatable growth process. We give no credit for share gains, the e-commerce advertiser push, or margin expansion. Base case, $101 per share. Earnings hold flat at $10.77 for ten years, then fade in a straight line to zero over the following ten years. The evidence for holding is three straight years of results and the first half of 2026. The reason for the fade is that customers can leave at any time, and Apple and Google control the mobile app stores the platform depends on, including Apple's privacy rules on device advertising identifiers in place since 2021. Bear case, $48 per share. Competition, or changes to Apple or Google platform rules, cut earnings to about $8.10 a share in year 1 and about $5.40 from year 2, roughly half of 2025 and close to the $5.97 earned in 2024. Earnings hold there through year 10 and then fade to zero over five years. This is built from disclosed exposures: cancellable contracts, dependence on the two app stores, $3.6 billion of fixed-rate debt, and recent write-downs (a $189 million goodwill impairment tied to the Apps business in 2025 and a $50 million impairment of an investment in Humans, Inc., a company whose own condition raised doubt about its ability to continue as a going concern). Bull case, $143 per share. Earnings run at about $14 a share from year 1, in line with the first half of 2026 (net income plus depreciation of about $2.5 billion in six months, or roughly $15 a share annualized, trimmed to allow for higher taxes), hold for twelve years and then fade to zero over ten years. It uses only results already delivered in the two most recent quarters and does not assume the e-commerce expansion succeeds. What could prove this wrong. If AppLovin loses share to competing ad networks, or the app stores change their rules, value falls toward the bear case; if the 2026 pace is sustained and taxes stay low, value is nearer the bull case. The base case's assumption that earning power lasts a decade rests on the platform's record, and it is tested by the company's own filing, which says advertisers can cancel at will and that platform owners can change their policies, which is why every case fades rather than running forever. The 2025 figures reconcile to net income plus non-cash charges to within 1%. Margin-of-safety price. The margin-of-safety price is about $52 a share, roughly half the base case and close to the bear case. At that price 2025 earnings represent a yield of about 21% with no growth, and the discount reflects a young, cancellable, platform-dependent revenue stream.
