Alphabet stock drops on cash flow miss

Alphabet shares declined approximately 10 percent during premarket trading on Thursday following the release of third-quarter financial data. The drop was driven by a report of negative free cash flow, a metric that tracks the actual cash a company has after paying for its operations and capital investments. If the stock closes down more than 9.77 percent, it will record the company’s worst single-day reaction to earnings since its initial public offering in 2004.

The parent company of Google posted negative free cash flow of $9.07 billion for the quarter. This figure fell well short of the $2.70 billion shortfall anticipated by Wall Street analysts. Despite the quarterly miss, Alphabet maintained its full-year capital expenditure guidance at a range between $195 billion and $205 billion. The company also reported that search advertising revenue, its largest income stream, increased 12 percent to $63.35 billion. However, this growth rate did not meet analyst expectations, adding to the pressure on the share price.

Philipp Schindler, the company’s chief business officer, attributed the revenue shortfall to lower monetization within the company’s AI Mode. He stated that Alphabet is currently scaling advertising within its AI Overviews and AI Mode products, including in international markets. The search business faces competition from rival AI chatbots such as OpenAI’s ChatGPT and Anthropic’s Claude. These tools may be diverting user queries away from the traditional Google search engine. The company’s own chatbot, Gemini, has not yet matched the adoption rates of these competitors.

In contrast, Microsoft shares gained nearly 4 percent in the same premarket session. The company reported $45.2 billion in capital expenditures and finance leases for the quarter. This amount represented a 30 percent year-over-year increase but came in below the $50.67 billion forecast by analysts. Microsoft’s free cash flow decreased by 27 percent to $18.63 billion, yet it remained a positive figure. This steadier financial picture allowed investors to view the company’s spending plans more favorably compared to Alphabet.

Ben Barringer, global head of technology research at Quilter Cheviot, noted that Microsoft is building its infrastructure in a measured way with fewer surprises. He described Alphabet’s results as messy and the earnings call as poorly handled. Barringer argued that Google faces an innovator’s dilemma, unsure whether to protect its core advertising business or join the disruption. He added that the company has lost its edge with Gemini and is behind its peers in agentic AI development.

The divergence in stock performance highlights how investors are scrutinizing the return on AI spending across the tech sector. Nasdaq-100 futures were down more than 1 percent early in the session, reflecting the broader market reaction to Alphabet’s news. The companies’ results arrive as investors examine whether massive AI infrastructure investments are generating sufficient returns to justify the high capital costs.

Alphabet’s search advertising revenue growth of 12 percent to $63.35 billion remains a key indicator of its core business health. The company’s decision to keep full-year capital expenditure guidance unchanged suggests it remains committed to its long-term spending plans despite the quarterly cash flow issues. Microsoft’s positive free cash flow of $18.63 billion stands in stark contrast to Alphabet’s negative $9.07 billion, a difference that likely influenced the divergent stock movements on Thursday.
