Alphabet: AI Spending Eats Free Cash Flow – Cheap Or Compromised?

First Eagle still maintains Alphabet as a top holding, according to its latest 13F filing. The filing follows Alphabet's Q2 2026 earnings release on July 22, where the company posted strong revenue growth of 24% year-over-year to $119.8 billion, yet its stock fell more than 1% in extended trading as investors fixated on surging capital expenditures and deteriorating free cash flow.

The question is whether the market has mispriced the stock by demanding too much execution risk, or whether the capex burn rate genuinely changes the investment case at this level.

What Changed After Earnings

Alphabet's top line is strong. Revenue hit $119.8 billion, well above the $116.9 billion consensus estimate, driven by demand across both its advertising businesses and Google Cloud. Cloud revenue surged 82% year-over-year to $24.8 billion, accelerating from the 63% growth in the prior quarter. The AI infrastructure boom is fueling enterprise demand for cloud capacity, and Alphabet has landed major deals with firms including Anthropic.

But the market's focus quickly shifted from growth to spending. Management raised its 2026 capex guidance to $195–$205 billion, a significant increase from the $187.1 billion consensus estimate that was already priced into the stock. Alphabet's trailing twelve-month capital expenditures already stood at $132.4 billion. The company is accelerating its buildout of data centers and AI chips, and that spending is directly compressing free cash flow. FCF growth year-over-year dropped 20.16% on a trailing basis, and reports indicate Alphabet posted negative free cash flow in Q2 2026 for the first time as AI capex outpaced operating cash generation.

That matters because free cash flow has long been the bridge between Alphabet's growth story and its valuation discipline. A company can sustain massive capital spending if operating cash generation keeps pace, but when FCF conversion deteriorates, the multiple the market assigns to those earnings becomes less secure.

Valuation: Still Cheap Or Already Stretched?

The picture splits depending on which valuation metric you trust. Alphabet's trailing P/E sits at 18.0x, which looks inexpensive for a company growing revenue at 20%+. Its PEG ratio (trailing P/E divided by growth rate) is 0.16, suggesting the stock has traded well below its growth rate for years.

But forward P/E tells a different story: 35.1x. The forward multiple embeds expectations for continued rapid growth in AI-driven cloud and advertising revenue, while also assuming the current earnings surge from recent quarters persists. If Alphabet's capex cycle continues to pressure near-term FCF and operating leverage, that forward multiple looks stretched. The stock has pulled back roughly 11% from its 52-week high of $404.47 to trade around $360 – a valuation reset, but not a crash.

Against peers, Alphabet's trailing P/E of 18.0x sits below Microsoft (27.1x), Meta (22.0x), and Amazon (21.7x). Alphabet is growing revenue faster than Meta while trading at a substantially lower multiple. But Alphabet's AI narrative has faced headwinds that its peers have not: delays to its Gemini 3.5 Pro model launch, departures of high-profile AI research talent, and a cloud business that remains the third-largest behind Microsoft Azure and Amazon Web Services. Microsoft's AI narrative in Copilot and Azure has allowed it to command a premium multiple. Alphabet's lag in AI execution is what the market is now punishing.

The Operating Phase

Alphabet's profitability metrics remain robust. Operating margins sit at 32.7%, gross margins at 60.4%, and EBITDA margins at 38.2%. ROIC stands at 16.5% and ROE at 49.6%, reflecting a business that generates impressive returns on deployed capital. The balance sheet is strong: $55.9 billion in cash, net debt of negative $144.3 billion, and a debt-to-equity ratio of just 15.3%. There is no solvency risk.

The tension is between current profitability quality and near-term cash flow drag from capex. Alphabet is investing heavily to maintain its position in the AI race, and that spending will depress FCF for quarters ahead. The market is now demanding evidence that this capex translates into durable revenue growth and margin expansion, not just burn rate.

Google Cloud is the key proof point. It is growing at 82% year-over-year. Can it sustain that acceleration while competing with two larger cloud providers that are also raising capex to massive levels? Big Tech is expected to spend over $700 billion this year primarily on AI, with Morgan Stanley estimating the figure could exceed $1 trillion next year. The question is whether Alphabet's $200 billion+ annual capex program will generate returns justifying the outlay.

Stanley Druckenmiller exited his entire Alphabet position in Q1 2026, a move that aligns with broader smart-money caution on AI-heavy capex names. The capex cycle has introduced uncertainty that investors are pricing in, not just through lower multiples but through reduced position sizes.

Hold. Wait for the Cash Flow Proof.

Alphabet is not a bad company, and it is not expensive by trailing valuation standards. But forward expectations are high, free cash flow is deteriorating, and the capex guidance raise shifts the near-term risk/reward balance. At $360, the stock offers some downside cushion from its $404 high, but the forward P/E of 35x still demands continued strong growth execution to justify.

The next earnings report in late October will be critical. Investors will want to see whether Google Cloud can sustain its 80%+ growth trajectory, whether FCF begins to stabilize after the capex spike, and whether management provides clarity on the return profile of its AI infrastructure investments. If Alphabet demonstrates that its spending is translating into margin expansion and accelerating bookings, the stock could easily rally back toward its highs.

Until then, the market's skepticism is warranted. Hold existing positions if you have them. New buyers would be wise to wait for clearer evidence that Alphabet's AI capex cycle is paying off.

If FCF stabilizes in Q3 and Q4 while cloud growth stays above 60%, this becomes a Buy again at current levels. If capex continues to escalate without a commensurate revenue response, the forward multiple will compress further.
