Alphabet Inc. (NASDAQ: GOOGL) saw its stock decline 1.4% to close at $347.15 on Tuesday, as market participants braced for the company's second-quarter earnings report, scheduled for release on Wednesday after the market close. The dip came amid growing concerns that the tech giant's capital expenditure is rising at a pace that significantly outstrips revenue gains, a trend that is drawing scrutiny from investors focused on return on investment.
According to preliminary estimates, Alphabet's capital expenditure for the second quarter is projected to reach approximately $45 billion, a staggering increase of about 100.5% compared to the $22.45 billion spent in the same period last year. In contrast, total revenue is expected to rise by 21.3% to $116.93 billion. This divergence means that capital spending would account for 38.5% of projected revenue, up sharply from 23.3% a year earlier. The absolute increase in capex of $22.6 billion surpasses the anticipated revenue growth of $20.5 billion by roughly $2.1 billion, highlighting a significant intensification in cash intensity.
The market's reaction was notable given that the broader Nasdaq Composite index rose 1.29% on the same day, underscoring a 2.7 percentage point performance gap. U.S. cash markets were closed at the time of the stock's settlement, with after-hours trading reflecting the cautious sentiment. Alphabet shares have slipped 3.4% compared to their level on July 14 and are down 2.9% for the week ending July 17, though they remain up nearly 13% year-to-date.
Cloud Growth Drives Revenue but Strains Margins
Google Cloud continues to be a primary growth engine, with estimated second-quarter revenue of $22.34 billion, representing a 64% year-over-year increase. This segment now accounts for approximately 19% of total sales and contributes 43% of incremental revenue. In the first quarter, cloud revenue exceeded expectations at $20.0 billion, with an operating margin of 32.9% and a backlog of $462 billion. Management previously indicated that slightly more than half of this backlog is expected to convert to revenue within the next 24 months.
However, the rapid expansion of cloud operations comes with capital demands. Free cash flow in the first quarter was $10.1 billion after capital expenditures of $35.7 billion. For the full year, Alphabet maintains a capital expenditure guidance range of $180 billion to $190 billion. Equity offerings totaling approximately $85 billion represent nearly 46% of the midpoint of that range, raising questions about potential dilution.
Advertising Revenue Remains Core
Google's advertising business, which is expected to generate approximately $81.11 billion in revenue for the second quarter—a 13.7% increase from $71.34 billion a year ago—remains the company's primary profit driver, accounting for nearly 69% of total revenue. The $9.8 billion year-over-year increase in ad revenue underscores the resilience of search and display advertising, even as the company invests heavily in artificial intelligence and cloud infrastructure.
On Tuesday, Google launched three lower-cost Gemini AI models, signaling an effort to broaden its AI offerings. However, the company did not provide an updated timeline for the release of Gemini 3.5 Pro, which was postponed from June. This delay adds to the complexity of assessing product execution and its impact on demand signals.
Investor Concerns and Key Metrics to Watch
Dave Wagner, portfolio manager at Aptus Capital Advisors, described AI coding as a “very real growing concern,” noting that Alphabet's strategy revolves around its ecosystem. Market watchers are now focusing on several critical metrics in Wednesday's earnings report: cloud profitability, capital expenditure guidance for 2027, and the rollout schedule for Gemini. Surpassing revenue forecasts may not be sufficient to alleviate concerns about the returns on the company's elevated investment levels.
Execution and funding risks remain primary concerns. Increased capital expenditures, declining cloud profit margins, additional share dilution, or further delays in AI model releases could exert downward pressure on the stock. The three main figures investors will be watching are capex, cloud margin, and free cash flow, as these indicators will reveal whether operating returns are aligning with the company's spending trajectory.
Alphabet's earnings conference call is scheduled for 4:30 p.m. Eastern Time on Wednesday, where management is expected to address these issues in detail.
