Meta Platforms (NASDAQ: META) shares moved modestly lower after the company reported record second-quarter revenue alongside a steep drop in free cash flow driven by aggressive artificial intelligence infrastructure investment. The market response centered on the widening gap between top-line growth and cash generation rather than the company's strong advertising performance.

Meta's stock closed regular trading down 1.3% at $585.61, with additional weakness in after-hours trading as investors digested the company's updated spending outlook and softer near-term revenue guidance.

Cash Flow Squeezed by AI Buildout

Meta generated $60.8 billion in revenue during the quarter, representing 28% year-over-year growth and slightly exceeding Wall Street expectations. However, free cash flow collapsed to just $780 million, down from $8.55 billion in the same period a year earlier, as the company poured resources into expanding its AI infrastructure.

Capital expenditures, including lease-related payments, surged 83% year over year to $31.08 billion — consuming nearly all of Meta's operating cash flow and leaving minimal cash available after investment spending. The company's free-cash-flow margin plummeted to 1.3% from 18% a year earlier, underscoring the scale of Meta's push into data centers, computing equipment, and other AI-related infrastructure.

The figures reflect Meta's deliberate prioritization of long-term AI capacity over near-term cash efficiency — a tradeoff that has become the focal point for investor scrutiny. Meta's spending trajectory mirrors a broader capital expenditure surge across the largest U.S. technology companies, with Alphabet, Microsoft, and Amazon collectively directing tens of billions of dollars toward AI data centers, custom silicon, and energy infrastructure. Meta has identified its Llama family of large language models and its Meta AI assistant as central to justifying this buildout, positioning the company to compete with OpenAI, Google, and others in the consumer and enterprise AI market.

Advertising Business Remains Robust

Despite the cash-flow deterioration, Meta's core advertising business continued to perform well. Advertising revenue climbed 27% to $59.36 billion, driven by both higher ad prices and increased user engagement across the company's family of apps.

Ad impressions rose 14% year over year, while the average price per ad increased 12%. Daily active users reached 3.6 billion, up 3% from the prior-year period, demonstrating that Facebook, Instagram, WhatsApp, and Messenger continue to command massive global audiences.

Chief Executive Mark Zuckerberg stated that AI is already enhancing Meta's core business, particularly through improved content recommendations and advertising performance. While the revenue figures largely support that assertion, investors appear to be awaiting clearer evidence that AI investment can translate into stronger cash generation.

Profitability Pressures Mount

Meta's profitability weakened during the quarter. Earnings per share came in at $6.18, falling short of analyst expectations, while net income declined 14% to $15.85 billion. Operating margin fell to 31% from 43% a year earlier, reflecting the combined impact of higher infrastructure spending, legal expenses, severance costs, and broader operating-cost inflation.

Reality Labs, the division overseeing Meta's virtual and augmented reality initiatives, posted a quarterly loss of $4.62 billion. Even excluding one-time items, overall costs rose sharply, indicating that profitability pressures extend well beyond exceptional charges.

Forward Guidance Adds to Investor Caution

Meta raised the lower end of its 2026 capital expenditure outlook to a range of $130 billion to $145 billion and projected full-year expenses of $165 billion to $169 billion.

For the third quarter, the company guided revenue of $61 billion to $64 billion, with the midpoint slightly below Wall Street expectations. The softer outlook compounded investor concerns that spending is accelerating faster than near-term growth.

Analysts are increasingly focused on whether Meta's AI investments can produce meaningful revenue and improve cash flow over time. The stock has declined approximately 13% since mid-July, reflecting market caution over whether robust advertising growth can offset the financial strain of heavy infrastructure spending.
