Alphabet (GOOG) Q4 2025 earnings review
Cloud Explodes to +48%, but the $180 Billion Price Tag Shocks
Alphabet delivered a blockbuster quarter, with total revenue accelerating to 18% growth ($113.8B). The headline story is Google Cloud, which accelerated violently from 34% growth in Q3 to 48% in Q4, validating the company's AI infrastructure dominance. Net Income surged 30% to $34.5B. However, the celebration is tempered by a staggering capital requirement: management guided FY26 CapEx to $175-$185 billion. While the growth engine is firing on all cylinders, the cost of fueling it has doubled.
🐂 Bull Case
Google Cloud revenue accelerated significantly to 48% YoY ($17.7B). Operating income for the segment more than doubled to $5.3B. This confirms that enterprise demand for Gemini and AI infrastructure is not just hype—it is generating massive, profitable revenue now.
Despite fears of displacement by chat bots, 'Google Search & other' revenue grew 17% to $63B. The core business remains an impenetrable fortress, funding the company's massive AI investments.
🐻 Bear Case
FY26 CapEx guidance of $175-$185 billion is a massive step up from FY25 levels (~$93B). This level of spend—roughly $45 billion per quarter—will weigh heavily on free cash flow and raises the bar significantly for required ROIC.
While Search and Cloud accelerated, YouTube advertising growth decelerated to 9% YoY ($11.4B), down from ~15% in Q3. This suggests potential maturity or competitive pressure in the video ad market.
⚖️ Verdict: 🟢
Bullish. The operational performance is undeniably excellent, with Cloud growth accelerating to levels not seen in years. The CapEx number is frighteningly high, but Google is the only company translating that spend into immediate, high-margin revenue growth (Cloud operating profit +153%).
Key Themes
Cloud Revenue Acceleration
Accelerating. Google Cloud is no longer just a 'strong' performer; it is the primary growth engine. Revenue growth jumped from 34% in Q3 to 48% in Q4. More importantly, operating margin expanded to 30% (up from 17% a year ago), proving that AI revenue is highly accretive to earnings.
The $180 Billion CapEx Bet
Accelerating. Management guided FY26 CapEx to $175-$185 billion. For context, total FY25 CapEx was $91.4B. This doubling of infrastructure investment indicates an aggressive arms race. While necessary to support the 48% Cloud growth, the depreciation drag on future earnings will be immense.
YouTube Ads Deceleration
Decelerating. YouTube advertising revenue grew 9% YoY to $11.4B. This marks a sharp slowdown from the 13% growth seen in Q2 and 15% in Q3. In a quarter where digital ad spend was generally robust (Search +17%), YouTube was a relative laggard.
Search Resilience
Stable/Accelerating. 'Google Search & other' revenue grew 17% YoY, accelerating from Q3. Despite the narrative that AI chatbots would cannibalize search queries, Google is monetizing higher volumes than ever ($63B in a single quarter). Innovations like AI Overviews appear to be additive rather than destructive to the ad model.
Waymo Valuation Charge
A specific $2.1 billion employee compensation charge related to Waymo weighed on GAAP results. While Waymo raised $16B in external/internal funding, the high costs of autonomy continue to drag on the 'Alphabet-level' unallocated segment, which posted a $5.9B operating loss.
Other KPIs
Stable. Margins held flat YoY (31.6% vs 32.1% in 24Q4) despite the $2.1B Waymo charge. Excluding that charge, margins would have expanded, driven by the massive profitability jump in Google Cloud.
Strong but pressured. Operating cash flow was huge ($52.4B), but the intense CapEx cycle ($27.9B) is consuming 53% of operating cash. As CapEx ramps to ~$45B/quarter in 2026, Free Cash Flow conversion will remain under pressure.
Accelerating. Up 30% YoY. The bottom line is growing significantly faster than the top line (18%), demonstrating operational leverage in the core Services and Cloud businesses, even with the Waymo headwinds.
Guidance
Accelerating. This is a massive increase from ~$91B in FY25. It implies a quarterly spend rate of ~$45B. Management cited 'growing opportunities' and customer demand, but this figure is unprecedented in the tech sector.
Stable. Payable March 16, 2026. Consistent with the previous payout levels.
Key Questions
CapEx ROI Timeline
With CapEx doubling to $180B in FY26, what is the expected timeline for this infrastructure to turn revenue-neutral or accretive? Is this purely demand-based (pull) or strategic capacity building (push)?
YouTube Deceleration
YouTube ads growth slowed to 9% while Search accelerated to 17%. Is this a result of macro mix shift, or is short-form video inventory (Shorts) continuing to dilute effective pricing?
Waymo Path to Profitability
With a $2.1B compensation charge and the 'Alphabet-level' loss ballooning to nearly $6B this quarter, when will Waymo financials move from a massive drag to a neutral contribution?
