This earnings season, cash burn has become a critical metric for investors evaluating Big Tech's massive artificial intelligence investments. With borrowing costs elevated, companies are under scrutiny for how they finance their AI infrastructure expansion and whether those investments will generate returns quickly enough.
Over the past two weeks, results from major technology firms have intensified concerns about the sustainability of the AI spending boom. Investors are increasingly distinguishing between companies that can fund expansion through operating cash flow and those whose spending pressures their balance sheets.
Microsoft was rewarded for demonstrating it can finance its AI ambitions without repeatedly tapping capital markets. In contrast, Alphabet, Amazon, and Meta faced pressure as their expanding infrastructure budgets weighed on free cash flow.
According to Reuters, more than $2 trillion in market value is set to be wiped from the tech-heavy Nasdaq 100 this month as investors reassess the AI investment boom's durability.
Alphabet, Amazon, and Meta Face Cash Flow Pressure
Alphabet's latest results highlighted the growing tension between AI investment and the financial performance of its established businesses. Google Cloud revenue more than doubled to $30.71 billion, showing strong demand for AI-related services. However, the company's free cash flow turned negative by $9.07 billion, substantially worse than the $2.70 billion analysts had expected.
Investors were also concerned about slowing growth in Google Search, which remains Alphabet's largest revenue source and helps finance its AI expansion. Search advertising growth slowed for a third consecutive quarter and missed analyst expectations, while YouTube advertising revenue also came in below estimates. Alphabet shares plunged 13% on Thursday, erasing approximately $500 billion in market value in its worst single-day decline.
Amazon also came under pressure after reporting a substantial cash outflow despite strong growth at its cloud computing business. The company burned $42.4 billion on a trailing 12-month basis in the September quarter, driven by capital expenditure of $77.26 billion, around $20 billion above estimates, according to LSEG data. This compared with cash burn of $7.6 billion in the previous quarter and positive free cash flow of $14.8 billion in the year-earlier period.
Amazon Web Services revenue increased 39% to $46 billion, beating expectations for growth of 38.2%. However, the strong cloud performance did little to offset concerns about the company's spending commitments and weaker retail outlook. "The free cash flow looks like the ugly part of the report," said Dave Wagner, portfolio manager at Aptus Capital Advisors, in a Reuters report. "Operations generated plenty of cash but their capex just absolutely swallowed it."
Amazon has forecast capital expenditure of $220 billion for this year as it expands its AI infrastructure and develops related services. Its shares fell around 2% on Friday.
Meta has also faced investor scrutiny after reporting negative free cash flow of $2.12 billion in the third quarter. The company raised the lower end of its full-year capital expenditure forecast to $135 billion from $130 billion, while maintaining the upper end at $145 billion.
Microsoft Stands Out with Stronger Cash Generation
Microsoft offered a contrasting picture, demonstrating that substantial AI investment does not necessarily have to come at the expense of cash generation. The company reported 48% growth in its Azure cloud business in the fiscal first quarter ended September and generated $18.6 billion in free cash flow, approximately $10 billion above analyst expectations.
The results provided evidence that its investments in AI infrastructure and cloud capacity are translating into stronger business growth while leaving sufficient cash to support further expansion. "Across all four hyperscalers, we saw there is growth in the cloud business and in demand for AI tools. But in terms of running the business of the business, Microsoft seems to be the only one that's able to do all of this and still (generate cash) at the same time," said Brian Mulberry, chief market strategist at Zacks Investment Management, in a Reuters report.
The difference is also reflected in their financing activities. While Microsoft has started raising capital through debt, its issuance has been considerably smaller than that of some competitors this year. Google has raised more than $140 billion through debt and equity offerings, while Meta has raised $62.5 billion and Amazon has garnered $98 billion through bond deals.
With interest rates making borrowing more expensive, companies that depend heavily on external financing could face greater pressure to demonstrate that their investments are generating adequate returns.
Core Businesses Also Face Growth Challenges
Another concern for investors is that the enormous spending commitments are coinciding with signs of weakness in some of the companies' established businesses. Amazon reported slower growth in both its retail and advertising operations. Online sales increased 2% year over year, down from 10% growth a year earlier and below analyst expectations. Its fourth-quarter revenue guidance also disappointed, with the midpoint falling below analysts' estimate of $244.5 billion, despite the period including the holiday shopping season.
Alphabet's search business has also shown signs of slowing as competition from ChatGPT, Claude, and other AI-powered chatbots and agents intensifies. Revenue in the search and other segment grew 12% from a year ago to roughly $63 billion, but came in below estimates for the second straight quarter. The company has to invest heavily in AI while protecting the search business that has historically funded its expansion.
