US Stock Market Move | AppLovin (APP.US) plummeted over 20% as Q3 guidance fell short of expectations.

On Thursday, the mobile advertising platform giant AppLovin (APP.US) plummeted over 20%, closing at $333.71. The earnings report showed that for the second quarter ending June 30, AppLovin achieved revenue of $1.92 billion, a 53% year-over-year increase, but still fell short of the $1.94 billion that analysts had widely expected. Adjusted earnings per share were $3.76, slightly above the market consensus of $3.75. Net profit reached $1.27 billion, a significant increase of 55% from $820 million in the same period last year; adjusted EBITDA was $1.61 billion, up 58% year-over-year. However, what raised caution in the market was that this report not only failed to meet Wall Street expectations but also fell below AppLovin's own internal guidance. Co-founder and CEO Adam Foroughi candidly stated in the conference call that the company's game-focused advertising business is highly dependent on the performance improvements of its AI model. Each substantial iteration of the model allows advertisers to invest more budget while maintaining their targeted return on ad spend. However, in the recently concluded second quarter, such performance leaps of the model did not materialize as expected. For the current quarter, AppLovin provided performance guidance reflecting the contributions of the new model. The company expects third-quarter revenue to be between $2.055 billion and $2.085 billion, with a year-over-year growth rate of about 46% to 48%, and a midpoint of $2.07 billion, slightly below the $2.08 billion widely anticipated by analysts. Adjusted EBITDA is expected to range between $1.71 billion and $1.74 billion, with an adjusted EBITDA margin of about 83%. CFO Matt Stumpf indicated that the third-quarter guidance has accounted for increased costs in training and computational infrastructure due to the deployment of the new model but does not include potential future model releases that may not yet be realized. He reiterated that the company's core management metrics are based on absolute EBITDA figures and free cash flow, and as long as the investment in computing power can generate incremental revenue, the company will continue to invest. In the long term, the adjusted EBITDA margin is expected to remain in the low 80% range, but short-term fluctuations may occur due to infrastructure investments.
