Key Highlights

● Microsoft shares edged lower on October 29 after early gains evaporated.

● Fiscal first-quarter Revenue reached $92.3 billion and non-GAAP EPS of $4.89 topped estimates.

● Capital spending of $45.2 billion came in below the roughly $50 billion analysts expected.

● Second-quarter guidance: revenue of $96 billion to $97.1 billion, capex above $50 billion.

Microsoft (NASDAQ:MSFT) beat on revenue and Earnings and spent less than expected on capex, yet its early gains evaporated as an AI sell-off swept Big Tech on Thursday.

From gain to flat

Microsoft looked like the winner of Big Tech's Wednesday night earnings double-header. It rose sharply in after-hours trading on October 28, according to market data, and was still higher before the opening bell on Thursday. By the close, the gains were gone. The stock edged lower on October 29, according to market data, though accounts of the move differed: another source had the stock down more steeply at midday, at $522.92.

The Reversal came even though one report described Microsoft's quarter as "a big cash-flow beat."

What Microsoft delivered

The fiscal first-quarter numbers were strong. Revenue reached $92.3 billion, and non-GAAP EPS of $4.89 topped the $4.72 consensus, according to market data. Microsoft Cloud revenue hit $63.9 billion, and Azure growth stayed strong, with the company guiding to a similar pace for the coming quarter.

Chief financial officer Amy Hood said: "Our results exceeded expectations across revenue, operating income, and earnings per share." Chief executive Satya Nadella called Copilot "the new OS for work."

Capital spending was the twist. Microsoft spent $45.2 billion including leases, below the roughly $50 billion analysts expected. The company blamed delayed third-party capacity, according to another source, and Hood said customer Demand "continues to exceed available supply." For the second quarter, Microsoft guided revenue to $96 billion to $97.1 billion and capex above $50 billion.

Why the stock still slipped

The broader market likely explains much of it. Alphabet (NASDAQ:GOOGL) suffered its worst day since its 2004 IPO, losing about $500 billion of market value, and its results revived concerns about AI costs. The Nasdaq Composite lost 365.13 points to 26,184.72, and information technology was one of only three S&P 500 sectors to fall.

Microsoft's lower capex had ripple effects of its own. AI-cloud providers CoreWeave (NASDAQ:CRWV) and Nebius (NASDAQ:NBIS) fell after Microsoft pointed to a lower capex commitment, according to market data.

A relative winner

Still, a flat-to-lower close looks very different from Alphabet's collapse. The test investors were applying was whether a company could show both strong growth and some restraint on what that growth costs. One market commentator put it this way: "Microsoft provided both, and that eased some of the worry about what its growth is going to cost."

One market analyst framed the day's bigger message: "markets are no longer rewarding companies simply for investing heavily in AI." By that standard, Microsoft's cash-flow strength appeared to help it hold up far better than its search rival.

The market around it

The S&P 500 slipped 23.59 points to 7,720.39 and the Dow, where Microsoft is a component, lost 132.54 points to 52,342.56. But more than 400 S&P 500 stocks rose, and the Russell 2000 gained 28.71 points to 2,859.22. One market strategist said, "Money is rotating within the market rather than leaving it."

What to watch

The capacity constraint is the key thread. If Microsoft's capex rises above $50 billion as guided, investors will watch whether that unlocks more Azure growth and whether Cash Flow remains strong.

Results from Amazon (NASDAQ:AMZN) after Thursday's close add a direct comparison. AWS revenue reached about $46.0 billion, and Amazon kept its $220 billion capex plan, but its stock slid after hours. How investors weigh Azure against AWS, and both against Google Cloud, will shape the AI trade in coming sessions. Friday's Employment Cost index and the Federal Reserve's December 8–9 meeting, where futures lean toward a hike, round out the near-term calendar.
