AppLovin shares tumbled more than 3% on Wednesday after Edgewater Research analyst Joe Wittine warned that the mobile advertising company's market-share expansion had effectively plateaued, raising concerns about its premium valuation. Earlier market reports showed the stock down 5%, including a Benzinga Pro snapshot of a 3.42% decline at $317.50. Wittine expects slower revenue growth, pressure on AppLovin's net revenue spreads and margin pressure, with fourth-quarter growth forecast at 8% to 9% quarter-over-quarter. AppLovin reported $1.92 billion in revenue last quarter and guided third-quarter revenue to $2.055 billion to $2.085 billion, implying sequential growth of roughly 7% to 8.6%. He attributed the slowdown partly to MAX reaching a functional ceiling and identified Unity Software as a growing competitive threat. Wittine expects late-2026 and 2027 consensus estimates to move lower before the company's third-quarter earnings report.
