AppLovin Corporation (NASDAQ:APP) shares are trading lower Wednesday after Edgewater Research analyst Joe Wittine cautioned that the mobile ad platform’s market share expansion has effectively stalled.

Competition Seen Weighing on Growth Outlook

According to Investing.com, following fresh channel checks, Wittine set a materially lower bar for Wall Street, forecasting AppLovin’s fourth-quarter revenue growth at just 8% to 9% quarter-over-quarter. He concluded that the company’s share of wallet and share of voice metrics are no longer consistently growing from their already industry-leading levels. “This is primarily the inevitable result of MAX’s share reaching a functional ceiling, though our interpretation of feedback also increasingly indicates competition is compressing APP’s net revenue spreads, contributing to APP’s decel,” Wittine wrote.

AppLovin reported $1.92 billion in revenue last quarter and guided third-quarter revenue to a range of $2.055 billion to $2.085 billion, implying sequential growth of roughly 7% to 8.6%. Wittine’s fourth-quarter forecast of 8% to 9% growth suggests the company’s sequential growth trajectory is flattening rather than accelerating into year-end. The analyst was notably self-critical of his own May upgrade of the stock, which had assumed hybrid and in-app advertising growth would continue yielding incremental supply for MAX. He also flagged Unity as a growing competitive threat, noting its expanding scale is pressuring AppLovin’s net revenue spreads.

“This has turned into a show-me story,” Wittine said, adding that he expects late-2026 and 2027 consensus estimates to move lower before AppLovin’s third-quarter earnings report, though he views the reset as a healthy adjustment for Street sentiment.
