Alphabet shares dropped more than 7% premarket Wednesday after the search giant fell short of Wall Street’s fourth-quarter revenue expectations and announced big spending plans for its ongoing artificial intelligence buildout.

The company topped earnings estimates by 2 cents per share. Revenues came in at $96.47 billion, behind the $96.56 billion expected by LSEG. Alphabet’s revenues grew 12% overall from a year ago, while its YouTube advertising business, search business and services segment slowed year over year.

Alphabet also said it plans to spend $75 billion on capital expenditures as it builds out its AI offerings and races against megacap rivals to build out data centers and new infrastructure. The figure was much higher than the $58.84 billion expected by Wall Street analysts, according to FactSet.

Finance chief Anat Ashkenazi said the higher expenses will help “support the growth of our business across Google Services, Google Cloud and Google DeepMind.” She also said the spending will go toward “technical infrastructure, primarily for servers, followed by data centers and networking.”

The company expects capital expenditures to range between $16 billion and $18 billion. That was higher than the $14.3 billion estimate from FactSet.

JPMorgan analyst Doug Anmuth highlighted costs, capex and cloud revenue as the “culprits” for the stock’s post-earnings performance. Bernstein’s Mark Shmulik also noted that this is the third quarter that the stock move connects to Google’s cloud segment.

“If digital ad growth is akin to a long drive competition, then Google would be sitting comfortably here with strong Search and YouTube bombs down the fairway,” Shmulik said.

“But as the game shifts to the AI putting green, there’s little room for error with a slight cloud miss, a whopping CAPEX guide up to $75B for 2025, and lack of actionable operating leverage commentary leaves Google 3- putting for bogey,” he added.
