Alphabet (NASDAQ: GOOG) (NASDAQ: GOOGL) is spending more cash than it's generating, and investors are worried. The company's capital expenditures totaled $51.4 billion last quarter, mostly related to its artificial intelligence (AI) compute build-out. That number could continue to climb in the fourth quarter and in 2027.
Many investors are concerned that Alphabet is overextending itself, raising additional capital to fund a speculative investment. That sentiment caused shares to tumble after the company's third-quarter earnings release. For long-term investors, the most important detail came during the company's earnings call, when CFO Anat Ashkenazi revealed everything you need to know in a single sentence.
Missed AI's "Act 1"? Act 2 Could Be 14x Bigger. Most investors think they missed the AI boat because they didn't buy Nvidia in 2005. But according to our analysts, we're only at the end of "Act 1"—the R&D phase. "Act 2" is the global rollout. Continue »
For years, Alphabet ran a business with extremely low capital intensity. It collected ad revenue from web searches (Google) and user-generated videos (YouTube). Its dominance in both categories made it a highly profitable business, and it used some of those profits to invest in moonshots (Other Bets) and buy back its stock. Investors could count on strong free cash flow generation quarter after quarter, but Alphabet's opportunities to deploy its excess cash were relatively limited.
With the AI boom, Alphabet has found the opportunity to deploy that cash. In fact, it has an opportunity to deploy more cash than it has, hence why it's raised tens of billions in equity and debt over the last few years. It raised $40 billion last quarter alone.
CFO Anat Ashkenazi explained exactly why the company is raising additional capital to fund the build-out. "Throughout this investment cycle, we expect to generate an attractive ROIC that remains meaningfully above our cost of capital and anticipate generating strong cash flow from operations," she said during the third-quarter earnings call.
Warren Buffett agrees. He initiated a position in Alphabet stock for Berkshire Hathaway last year, which has now grown to be the conglomerate's fourth-largest position in its marketable equity portfolio. His thesis was that Alphabet has an opportunity to generate a high return on capital while putting an enormous amount of capital to work.
Not only is Alphabet positioned to invest a ton of capital, but its massive spending also might not have nearly as much risk as the market is pricing in.
Alphabet has an advantage over other hyperscalers for generating a strong return on invested capital: It's the only company with a full stack of artificial intelligence products and services. It designs popular Tensor Processing Unit (TPU) chips for both training and inference. TPU chips are gaining broad adoption among leading developers, and Alphabet is now selling TPU systems directly to third parties.
Alphabet also develops its own frontier large language models. Use of those models runs on Google Cloud. It runs a security and governance platform for AI. And it's an end user of AI itself, with integrations for its core Search product on both the search results and advertising sides, not to mention its Gemini chat app that now counts over 1 billion users.
That level of vertical integration can lead to lower cost of ownership and shorter payback periods for its AI data center spending. That's supported by Google Cloud CEO Thomas Kurian's assertion that its server spending (about 65% of total capex last quarter) has a payback period of less than two years. For its own TPU systems, the payback period is half of that.
That payback period compares very favorably with other disclosures from competing hyperscalers. Amazon, for example, said its payback period for its servers and networking equipment is nearly three years.
The long-term payoff for Alphabet could be massive. Free cash flow could rise from around $50 billion (adjusted for stock-based compensation) before the investment cycle to more than $300 billion by 2031, according to the average forecast from analysts. That speaks to the high potential return on invested capital for Alphabet's cloud infrastructure.
That said, investors should expect a deeper drop in free cash flow in 2027 as spending continues to ramp up. Keep in mind Ashkenazi's statement that ROIC remains meaningfully above the cost of capital. As long as that remains true, the value of the business improves with each dollar invested in new data centers.
