App stock plunged in after-hours trading on Wednesday, August 5, 2026, after AppLovin reported a quarterly revenue miss and issued third-quarter guidance below Wall Street’s demanding expectations. Shares fell as much as 28% before recovering slightly, and were trading roughly 17% lower after hours at the time of the report.

The sharp decline came despite the company revealing that a U.S. Securities and Exchange Commission inquiry into its business practices had been closed without recommended action. The mixed update left investors balancing strong growth figures against concerns about artificial intelligence performance, rising computing costs and elevated expectations for the advertising technology company.

Why App Stock Fell After AppLovin’s Earnings

AppLovin’s second-quarter revenue increased 53% year over year to $1.924 billion. However, the result fell just below analysts’ consensus estimate of approximately $1.94 billion. Adjusted core profit rose 58% to $1.61 billion, slightly below the company’s previous guidance range.

Diluted earnings per share came in at $3.76, narrowly ahead of the $3.75 estimate. While the earnings-per-share result was essentially in line, investors focused more heavily on the revenue shortfall and the company’s outlook for the next quarter.

For the third quarter, AppLovin forecast revenue between $2.055 billion and $2.085 billion. The midpoint was below Wall Street’s estimate of $2.08 billion. The company projected adjusted core profit of $1.71 billion to $1.74 billion, compared with an analyst estimate of $1.75 billion.

Critical AI Model Delays Weighed on Growth

AppLovin’s advertising business depends heavily on AI-powered algorithms that determine which advertisements should be shown to individual users. These systems are designed to improve campaign performance and help advertisers generate stronger returns.

CEO Adam Foroughi said the second-quarter revenue miss was linked to slower-than-usual improvements in the company’s core gaming advertising models. He explained that the pace of meaningful model improvement was lighter than normal during the quarter, while the next major performance upgrade arrived shortly after the reporting period ended.

Foroughi emphasized that advertiser demand remained healthy. E-commerce customers, for example, spent 28% more during the quarter’s peak season than they did during the comparable period last year. Still, investors appeared concerned that delays in AI model development could affect the company’s rapid growth story.

Higher spending on computing power also pressured the quarter. Training and improving AI models requires significant data-center capacity, and AppLovin said those expenses weighed on its results. Foroughi nevertheless maintained that the company could compound growth at approximately 30% annually over the longer term.

SEC Probe Closed Without Enforcement Action

During the earnings call, CFO Matt Stumpf said the SEC had concluded its inquiry into AppLovin with no recommended action. He added that the company was pleased to have the matter resolved and said no enforcement action or findings of wrongdoing had been issued.

The inquiry was first reported in late 2025 and focused on AppLovin’s data-collection practices. It followed a sealed whistleblower complaint and several reports from short sellers. Those reports alleged that AppLovin may have violated service agreements with platform partners, including Apple, Google and Meta.

The allegations centered on the claimed use of unauthorized “fingerprinting” techniques to collect proprietary user identifiers and improve ad targeting. As of February 2026, the investigation had still been described as active and ongoing. The company’s latest disclosure removes an important regulatory overhang, although the stock’s immediate reaction showed that investors were more focused on growth and guidance.

Management Points to a Stronger Third Quarter

AppLovin’s management said the latest AI model improvements were already live and that the business had returned to its expected trajectory. The company also indicated that the third quarter had begun strongly.

That reassurance did little to prevent the initial selloff. App stock has fallen about 38% year to date, adding to pressure on shareholders who had supported the company’s AI-driven expansion. The latest decline suggests that the market may be less willing to overlook even modest revenue misses when valuation and expectations remain high.

• Second-quarter revenue: $1.924 billion, up 53% year over year
• Adjusted core profit: $1.61 billion, up 58%
• Diluted EPS: $3.76
• Third-quarter revenue outlook: $2.055 billion to $2.085 billion
• SEC inquiry: Closed with no recommended action
• Year-to-date stock performance: Down approximately 38%

What Investors Are Watching Next

The next major test for AppLovin will be whether its newest AI model improvements translate into stronger advertising performance and renewed revenue momentum. Investors will also monitor computing expenses, gaming-ad demand and the company’s ability to meet its third-quarter targets.

Retail traders appeared divided. Sentiment on Stocktwits remained in the “extremely bullish” range, while message volume climbed to extremely high levels. Some users described the after-hours decline as an overreaction, while others questioned whether the company’s AI-fueled growth narrative was beginning to weaken.

For now, the SEC news provides relief on the regulatory front, but AppLovin must still convince the market that temporary model delays—not a deeper slowdown—caused the latest disappointment.
