Revenue surged by 53%, yet faced a major sell-off! AppLovin (APP.US) plummeted over 25% in after-hours trading, simply because the AI model upgrade was a step too slow.

After hours on Wednesday, U.S. stocks saw mobile advertising giant AppLovin (APP.US) release a report showing a sharp increase in profits, yet it faced a harsh judgment from investors. The company's stock price plummeted by over 25% in after-hours trading due to slightly lower-than-expected revenue for the second quarter and a lackluster guidance for the next quarterdespite a 55% year-on-year surge in net profit and an adjusted EBITDA margin at a rare 84%. The earnings report revealed that for the second quarter ending June 30, AppLovin achieved revenues of $1.92 billion, a 53% increase year-on-year, but still fell short of analysts expectations of $1.94 billion. The adjusted earnings per share was $3.76, slightly exceeding the market consensus of $3.75. Net profit reached $1.27 billion, a significant 55% increase from $820 million in the same period last year; adjusted EBITDA was $1.61 billion, up 58% year-on-year, continuing to demonstrate strong profitability. However, the market was on high alert as the report not only failed to meet Wall Street expectations but also fell below AppLovins own internal guidance. In the subsequent earnings call, management attributed the underperformance to one word: timing. Pacing of model upgrades slowed, management elaborated on the "timing" issue. Co-founder and CEO Adam Foroughi candidly stated during the call that the company's game-focused advertising business heavily relies on improvements in its AI model's performance. Each substantive iteration of the model enables advertisers to invest more budget while maintaining their target return on ad spend. However, in the recently concluded second quarter, such enhancements in model performance did not materialize as expected. The issue this quarter boils down to timing, Foroughi explained. The pace at which we achieved meaningful model improvements was slower than usual, and the next significant leap in model performance happened to arrive just after the quarter ended. He emphasized that there was no observed weakening in advertiser demand or adverse changes in the competitive landscape; the publisher earnings on the MAX platform saw double-digit sequential growth, and AppLovin's share in the publisher bidding waterfall remained stable. This statement was intended to send a signal to the market: the growth engine itself has not stalled; rather, the timing of technological upgrades just happened to miss the financial reporting deadline. For the current quarter, AppLovin provided guidance reflecting the contributions of the new model. The company expects third-quarter revenue to be between $2.055 billion and $2.085 billion, representing an approximate year-on-year increase of 46% to 48%, with the midpoint of $2.07 billion slightly below analysts' general expectation of $2.08 billion. Adjusted EBITDA is expected to be between $1.71 billion and $1.74 billion, with the adjusted EBITDA margin around 83%. CFO Matt Stumpf pointed out that the third-quarter guidance accounts for increased training and computation infrastructure costs due to the deployment of the new model but does not include future model releases that may go live but have not yet materialized. He reiterated that the company focuses on absolute adjusted EBITDA and free cash flow as core management metrics, and as long as computational investments generate incremental revenue, the company will continue to invest. Stumpf stated that, in the long term, the adjusted EBITDA margin is expected to remain in the low 80% range, though it may experience fluctuations in the short term due to infrastructure investments. Record consumer advertising, the second growth curve is still taking shape. Beyond gaming, AppLovin is actively venturing into the broader consumer advertising sector such as e-commerce. Foroughi revealed that consumer advertising spend reached a record high in the second quarter, surpassing typical peak season levels by 28% compared to the fourth quarter of 2025. Nonetheless, this segment is still not large enough to fully offset fluctuations in the gaming business, but management anticipates its contribution will gradually strengthen. During the period, the company opened to the public a self-service advertising platform called AppLovin Ads Manager. Foroughi indicated that the initial target audience consists of mid-sized advertisers who have budgets and are willing to bear the learning costs of a new platform, rather than immediately competing for large brands or a multitude of small tail businesses. Currently, the system efficiently generates interactive landing cards, but there are still technical challenges to producing high-quality long video ads automatically; resolving these or launching alternatives would significantly lower the creative barriers for small and medium advertisers. Looking long term, Foroughi believes that the sustained optimization of the gaming advertising model combined with expansion into consumer businesses is expected to support the company in achieving an average annual compound growth rate of about 30%. In terms of cash flow, the free cash flow for the second quarter was $863 million. Stumpf explained that the lower-than-normal cash conversion rate was mainly due to the timing differences of international cash taxes and interest payments, not changes in profitability, and he expects improvement in the third quarter, with the annual free cash flow conversion rate likely returning to around 75% of adjusted EBITDA. The companys balance sheet remains robust, holding $3.05 billion in cash at the end of the quarter, with total debt at $3.7 billion and a net leverage ratio of only about 0.1 times, well below the long-term target of roughly 1 times leverage. In terms of buybacks, AppLovin spent about $551 million in the second quarter to repurchase and retire about 1.14 million shares, a significant slowdown compared to nearly $1 billion in buybacks in the first quarter. Stumpf clarified that this merely reflects a temporary drop in free cash flow for the quarter, and the companys stance on buybacks has not changed. As of the quarter's end, there remains about $1.8 billion of buyback authorization available. Additionally, Stumpf revealed that the voluntary inquiry by the U.S. Securities and Exchange Commission (SEC) has been closed without any action suggested, and the company does not consider this matter significant. Why the market turned cold: High expectations meet AI anxiety. Ahead of the earnings report, AppLovin's stock had already dropped about 40% from its high of over $740 this year, with the forward price-to-earnings ratio retreating from extreme exuberance to around 25 times, more in line with the typical valuation of the advertising technology sector. Because of this, a clean and crisp "beat" could have triggered a round of retaliatory rebounds. However, what ultimately emerged were slight misses in both revenue and guidance, providing new ammunition for the bears. Deeper unease remains associated with the disruption from AI. Despite AppLovin continuously highlighting that its Axon system utilizes AI for precise mobile ad matching and has successfully expanded beyond gaming, some investors remain wary of traditional software and advertising platforms that may be impacted by the AI wave. Analysts in the market are similarly divided: some optimists still maintain target prices well above $700, believing that recent sell-offs have been excessive, while cautious observers suggest that after the platform has matured, the easiest acceleration phase may have already passed. Ultimately, AppLovin's experience serves to illustrate the stringent logic of today's market: in a trading environment that relentlessly pursues "perfection," a company with an annual revenue growth rate still exceeding 50% is treated as a disappointment merely because its progress lagged slightly behind the most optimistic expectations. As revealed in its earnings report paradoxby almost any conventional standard, this quarter was strong, but in this climate, the term "strong" is far from sufficient.
