Welcome to the 3rd edition of Only Signals. Do not let the title fool you. We are not coming for McDonald’s old slogan. Instead, we are back to doing what we do best: finding companies the market is currently hazing and explaining why the bullies (or fraternity bros) are wrong.

Plain Signal is the engine behind it. It changes dense SEC disclosures into clear investment insights. This way you can spot opportunities and concerns with ease.

For our latest deep dive, we are breaking down the ad-tech giant, AppLovin.

AppLovin is the invisible toll booth for the mobile app economy. It has the software that helps developers find users and earn money from their content quickly. This is the kind of business investors label risky ad-tech, then ignore the fact that it has pivoted into a high-margin AI platform.

The headline today is simple. AppLovin surged about 7% yesterday, yet remains down 34% on the YTD due to AI-disruption.

Our take: AppLovin is significantly undervalued (30+%) for investors who can see past the gaming label. The market is pricing a legacy identity that no longer exists. In our read, the company has completed a successful skin-graft by replacing low-margin gaming revenue with elite AI-driven software profits.

The market loves to put companies in boxes. It sees AppLovin and thinks of cyclical advertising. That is a mistake. AppLovin is a software business masquerading as an ad network.

The Advertising segment now makes up 70% of the revenue as of late 2025. This is powered by their AXON AI engine. It does not just show ads, it uses machine learning to find the exact right user at the exact right microsecond. The results are visible in the margins. Net margins hit 33.5% in 2025. That is not an ad agency. That is a high-performance software machine.

For years, investors complained that AppLovin was too messy. It owned a bunch of mobile game studios that were slow-growing.

Management actually listened. They divested the entire Apps business in 2025. This removed the low-margin drag. The New AppLovin is now a dedicated AI engine. The market is often slow to notice when a company cleans up its room. They are still looking at the old, cluttered version while the new one is lean and mean.

Skeptics think the growth from AXON 2.0 was a one-time fluke. We disagree.

The company is now moving its engine into much larger ponds like e-commerce and Connected TV. They acquired Wurl to dominate the TV screen. If AXON can find you a pair of shoes as well as it finds you a mobile game, the growth runway is massive. Software Platform revenue grew 66% in Q3 2024. That is not the sign of a dying business.

Value investors see the $3.5 billion in debt and run away. They are missing the most important number.

AppLovin generated $3.95 billion in operating cash flow in 2025. That is nearly double its net income. Its capital intensity is almost zero. It spent only $5.8 million on property and equipment. It is using this mountain of cash to buy back shares and retire debt. It is a self-funding growth machine.

Nothing is perfect. If it were, the stock would be trading at all-time highs and we would instead be sitting feet-up with white sand and a frozen Mudslide.

Platform Dependency: AppLovin lives in a world controlled by Apple and Google. If Apple changes its privacy rules again, it could create friction for the AXON engine. This is a permanent tax on any mobile-first business.

Contract Volatility: Most of their advertising contracts can be canceled with two days' notice. This means they have to perform every single day to keep their revenue. There is no "locked-in" recurring revenue like a traditional SaaS company.

The takeaway: The market is currently obsessed with "what if" scenarios. What if Meta attacks? What if CloudX wins? While the market worries about "what ifs," the data shows what is. What is actually happening is a company generating the highest free cash flow margin of any tech stock in the S&P 500. Investors are mistaking temporary sentiment shifts for structural decay.

Most investors do not understand its’ value. While the rest of the software world is happy if they can grow 20%, AppLovin is doing something entirely different. It just grew revenue by 70% in 2025 and did it with 82% profit margins.

Its’ AXON engine isn't just a piece of code bur rather a massive data loop. Every time an ad is shown, the AI gets smarter. Because they process trillions of data points every day, it becomes nearly impossible for a newcomer to catch up. They have built a wall of data that keeps competitors out and keeps margins high.

The numbers back this up. In 2025, the company generated $3.95 billion in Free Cash Flow. They are so flush with cash that they bought back $2.58 billion of their own stock last year alone.

The signal is simple. You have a company guiding $1.76 billion in revenue for the next quarter (a 52% jump) while trading at just 25x forward PE. The market is scared of competition that hasn't proven it can beat the AXON AI Moat. Until that changes, AppLovin remains the most efficient cash machine in tech.
