Alphabet and Microsoft Deliver Divergent Wall Street Results Amid AI Spending Surge
Alphabet and Microsoft reported third-quarter earnings for the period ending in September, revealing contrasting financial results and market reactions driven by heavy investments in artificial intelligence infrastructure. While cloud divisions at both technology giants surpassed expectations, Alphabet shares dropped roughly 9% in after-hours trading due to a heavily negative free cash flow, while Microsoft shares rose up to 5% following stronger-than-expected liquidity generation, according to reporting by Il Sole 24 ORE.
Alphabet Reports Cloud Growth Alongside Record Capital Expenditures
Google Cloud more than doubled its revenues to reach $30.71 billion during the quarter, exceeding the consensus estimate of $29.57 billion as reported by Il Sole 24 ORE. The company utilized its custom-designed Tensor Processing Units alongside third-party graphics processing units to meet customer demand amid industry-wide shortages of advanced chips and electricity. Gemini models expanded further across enterprise software and developer platforms, supported by a partnership with Apple to power AI functions within the Cupertino ecosystem. Overall, Alphabet posted $127.6 billion in total revenue—marking a 25% increase from the previous year but falling short of the $128.22 billion consensus estimate. Earnings per share stopped at $2.12 against a projected $2.99.
Microsoft Posts Azure Revenue Gains and Better Cash Flow
Microsoft opened its fiscal year with Azure cloud revenues climbing 48% to $33.17 billion, slightly beating the expected $32.84 billion, according to Il Sole 24 ORE. Total company revenue reached $92.3 billion for the period. Capital expenditures rose to $45.2 billion from $34.9 billion a year earlier, remaining below the company’s prior projection of $50 billion and supporting a free cash flow that surpassed analyst forecasts.
Free Cash Flow Deficit Drives Investor Reactions
The divergent market responses centered on free cash flow—the liquidity remaining after funding data centers and chips, as detailed by Il Sole 24 ORE. Alphabet posted a negative free cash flow exceeding $9 billion, falling significantly short of analyst estimates. Conversely, Microsoft recorded $18.6 billion in free cash flow, more than double the $8.54 billion predicted by analysts. Yahoo Finanza noted that Alphabet’s capital expenditures surged 114% year-over-year to $51.4 billion, pushing operating cash flow below spending requirements and dropping the stock to $296.81 from $321.89. Milano Finanza confirmed that Alphabet recorded a negative free cash flow of $9.1 billion for the second quarter.
AI Investments Rely on Borrowed Capital
Alphabet’s heavy spending coincided with comments from Federal Reserve official Kevin Warsh, who expressed skepticism regarding the insulation of AI spending from higher interest rates, according to Yahoo Finanza reporting. Warsh indicated that elevated borrowing costs are already impacting the technology sector, while credit spreads widen as AI investments rely increasingly on borrowed capital. Data cited by Yahoo Finanza from a Bank of Korea report show that five major tech giants issued $230 billion in bonds over the year. Investing reported that Alphabet shares fell 8% in after-hours trading despite minor revenue beats, driven by profitability and cash generation concerns.
