AppLovin (NASDAQ: APP) delivered a third quarter that was not merely a beat but a statement. Revenue of $2.18 billion surged 55% year-over-year and cleared the $2.08 billion consensus by $107 million. Diluted EPS of $4.30 topped estimates by $0.26 and rose 75.5% from $2.45 a year ago. The market's reaction will be telling: this is a company that has now made beating-and-raising look routine, yet the magnitude keeps expanding.
The headline numbers are striking enough. Net income hit $1.44 billion, up 72% from $836 million, producing a 66% net margin that is rare for any software company at any scale. Adjusted EBITDA of $1.84 billion grew 59% and margin expanded 200 basis points to 84%. Those are not incremental improvements; they reflect a business model where incremental revenue flows through at very high marginal contribution.
What drove the outperformance? The release points to operating leverage, and the numbers back that up. Revenue grew $780 million year-over-year while total costs and expenses rose only $150 million. Cost of revenue as a percentage of sales dropped to 11.0% from 12.4%. Sales and marketing grew 42% but far slower than revenue, implying the platform's organic demand generation is reducing customer acquisition costs. Research and development spending more than doubled to $102 million, which is the one area where AppLovin is clearly investing ahead of growth rather than harvesting.
The Q4 guidance is the real signal. Revenue of $2.365–$2.395 billion implies sequential growth of 8–10% from Q3's $2.18 billion, which would represent another acceleration from the 55% YoY growth just reported. Adjusted EBITDA guidance of $1.995–$2.025 billion implies margin of 84–85%, essentially flat to Q3's 84%. Management is not guiding to margin expansion in Q4, which is a subtle but important point: they are prioritizing top-line momentum over incremental margin gains, suggesting the demand environment is strong enough to justify reinvestment.
The capital allocation story is equally aggressive. AppLovin generated $1.4 billion in operating cash flow and free cash flow during the quarter and deployed the entire amount to repurchase 4.1 million shares. That is a 100% payout ratio of free cash flow to buybacks, leaving nothing for debt reduction or M&A. The board then approved a $3.2 billion increase to the repurchase authorization, bringing the total to $3.6 billion. At the current run rate, that represents roughly 2.5 quarters of buyback capacity. The message is clear: management sees the stock as undervalued relative to the cash generation trajectory.
One note of caution buried in the cash flow statement: cash paid for income taxes surged to $926 million in the first nine months of 2026 from $167 million a year ago. That is a 5.5x increase, far outpacing the 75% growth in net income. The effective tax rate appears to have normalized upward as the company's profitability has grown. This is not a crisis, but it means the gap between net income and free cash flow will narrow over time as tax payments catch up to earnings.
The buyback pace also raises a question about balance sheet flexibility. Long-term debt sits at $3.52 billion, essentially unchanged from year-end 2025. With $3.17 billion in cash, net debt is negligible at roughly $350 million. But if the buyback continues at the Q3 pace of $1.4 billion per quarter, the cash balance will shrink quickly. The $3.6 billion authorization implies management is comfortable running with less cash, but investors should watch whether the company eventually needs to refinance or tap debt markets to fund the program.
For the rest of 2026, the key variable is whether Q4 guidance proves conservative. The midpoint of $2.38 billion implies roughly 55% YoY growth, matching Q3's rate. If AppLovin beats that by a similar margin as Q3, revenue could approach $2.5 billion. The guidance range is only $30 million wide, suggesting management has high conviction in the forecast. The real test will come in early 2027 when comps get tougher against the current growth surge. For now, AppLovin is executing at a level that few software companies have sustained at this scale.
