AppLovin and Trade Desk Diverge on Profit Margins and Growth Rates
AppLovin posted 70% revenue growth and a 60.8% net margin in FY2025, while Trade Desk grew 18.5% with a 15.3% margin. The divergence in scale and profitability defines the current investment choice.
AppLovin reported FY2025 revenue of nearly $5.5 billion, a 70% year-over-year increase, driven by its AI-powered advertising software. The company achieved a net income of approximately $3.3 billion, resulting in a net margin of 60.8%, up from 49% in the prior year. This expansion in profitability reflects the successful pivot to a pure software model after divesting its Apps business in June 2025.
Trade Desk generated FY2025 revenue of about $2.9 billion, representing an 18.5% increase. Net income reached roughly $443.3 million, translating to a net margin of 15.3%, a slight decline from 16.1% previously. The company’s financial profile is characterized by lower margins compared to its peer, reflecting the operational costs associated with its self-service cloud platform for connected TV and video advertising.
Balance Sheet Strength and Cash Flow
AppLovin’s December 2025 balance sheet shows a debt-to-equity ratio of 1.7x and a current ratio of 3.3x. Free cash flow for the period reached close to $3.9 billion, indicating strong internal liquidity to support its growth initiatives. The company’s leverage is moderate relative to its equity base, providing a cushion for operational needs.
Trade Desk maintains a significantly lower debt-to-equity ratio of 0.2x, signaling a conservative capital structure. Its current ratio stands at 1.6x, ensuring adequate coverage of short-term liabilities. Free cash flow for FY2025 was approximately $795.7 million. While the absolute cash generation is lower than AppLovin’s, the low debt load minimizes financial risk in a volatile advertising market.
Customer Concentration and Platform Risks
Trade Desk faces significant customer concentration, with two advertising holding companies each accounting for more than 10% of gross billings. The recent departure of Publicis highlights the vulnerability of its agency-based model to relationship shifts. This concentration creates a single point of failure that can disproportionately impact revenue if a major client reduces spend.
AppLovin’s primary risk stems from dependence on third-party mobile platforms, specifically the data policies set by Alphabet and Apple. Changes in how these operating systems handle user data can directly impair advertising effectiveness and revenue streams. Additionally, the company is managing ongoing securities class action litigation initiated in 2025, which introduces legal uncertainty into its financial outlook.
Valuation Metrics and Market Position
AppLovin trades at a forward P/E of 19.9x and a price-to-sales ratio of 19.2x. These multiples reflect the market’s premium for its high-growth trajectory and superior margin profile. The valuation suggests that investors are paying for the company’s ability to scale software efficiency across mobile and connected TV channels.
Trade Desk offers a lower entry valuation with a forward P/E of 15.6x and a price-to-sales ratio of 2.3x. This discount is attributed to its slower growth rate and higher customer concentration risks. Data from the tech stocks segment indicates that while Trade Desk provides a stable platform, its valuation does not command the same premium as high-margin software peers like AppLovin.
