While achieving rapid growth, the operating profit margin increased from 23.7% in the third quarter to 30% Alphabet, Google's parent company, reported strong fourth-quarter results, with both cloud services and search advertising accelerating growth, proving that its massive investments in artificial intelligence are paying off. The financial report released by Alphabet on Wednesday showed that revenue growth for Google’s search business accelerated from 15% in the third quarter to nearly 17%, while revenue growth for Google Cloud surged by 14 percentage points to 48%. This performance alleviated previous market concerns that AI chatbots might weaken Google’s search business. Based on fourth-quarter revenue, Google Cloud's annual revenue is projected to reach $71 billion, a significant leap from less than $20 billion in 2021. Notably, **the business achieved rapid growth while increasing its operating profit margin from 23.7% in the third quarter to 30%.** Despite the impressive results, Alphabet's stock fell by one to two percent in after-hours trading. The company announced that its capital expenditures would double this year to between $175 billion and $185 billion to build more computing capacity, a figure that exceeds the $164.7 billion cash flow it expects to generate in 2025. ## Cloud Business Achieves Scalable Profitability The performance of Google Cloud demonstrates that it has become a true business. Based on fourth-quarter revenue, the annualized revenue for this business reached $71 billion, an extraordinary achievement for a business that generated less than $20 billion in 2021. In comparison, industry leader Amazon Web Services (AWS) had an annualized revenue of $132 billion as of the third quarter. While a 30% operating profit margin is still lower than that of larger competitors, Google Cloud has finally proven itself to be a sustainable business. Few companies in the tech industry succeed in both consumer and enterprise markets; Amazon is one of the few, and Google appears to be on track to become another. Additionally, the growth of the search business should quell investors' concerns from a year or two ago that AI chatbots would undermine Google’s search business. Chief Business Officer Philipp Schindler stated during the analyst call that AI is helping Google improve ad effectiveness and enabling it to serve ads in more complex search queries than before. The revenue growth for Google Search accelerated from 15% in the third quarter to nearly 17% in the fourth quarter, demonstrating the positive impact of AI technology on its core business. ## Huge Capital Expenditures Raise Cost Concerns **Alphabet stated that it will double its capital expenditures this year to between $175 billion and $185 billion to build more computing capacity. This expenditure level exceeds the $164.7 billion cash generated by its business in 2025. The company has already increased its debt, and at this rate, it will have to borrow more funds in the future. The company has also cut back on stock buyback expenditures.** In addition to capital expenditures, Alphabet also needs to cover operational costs related to AI. The company separately listed the costs of its DeepMind AI research division, which grew more than double to $5.9 billion in the fourth quarter. Alphabet stated that this project mainly involves AI costs shared across various business units As of December 31 last year, the total number of employees at Alphabet reached 190,820, surpassing the peak level before the large-scale layoffs at the beginning of 2023. Although Alphabet's overall situation currently looks bright, especially compared to other companies, investors are currently uneasy about the costs associated with AI technology. This week's significant sell-off in software stocks is partly due to concerns that AI may undermine existing software businesses, and worries about the costs of AI development are also casting a shadow over the market ### Related Stocks - [SOXX.US - iShares Semiconductor ETF](https://longbridge.com/en/quote/SOXX.US.md) - [SOXL.US - Direxion Semicon Bull 3X](https://longbridge.com/en/quote/SOXL.US.md) - [GOOW.US - Roundhill GOOGL WeeklyPay ETF](https://longbridge.com/en/quote/GOOW.US.md) - [GOOGL.US - Alphabet](https://longbridge.com/en/quote/GOOGL.US.md) - [IDGT.US - iShares US Digital Infrastructure and Real Estate ETF](https://longbridge.com/en/quote/IDGT.US.md) - [DTCR.US - Global X Data Center & Dgtl Infrs ETF](https://longbridge.com/en/quote/DTCR.US.md) - [GOOG.US - Alphabet - C](https://longbridge.com/en/quote/GOOG.US.md) - [IGV.US - iShares Expanded Tech Software Sector ETF](https://longbridge.com/en/quote/IGV.US.md) - [CLOU.US - Global X Cloud Computing ETF](https://longbridge.com/en/quote/CLOU.US.md) - [NXTG.US - First Trust Index NextG ETF](https://longbridge.com/en/quote/NXTG.US.md) ## Related News & Research | Title | Description | URL | |-------|-------------|-----| | 6670 亿美元狂潮！巨头 AI 开支逼近顶点，自由现金流或触底反弹 | 高盛数据显示，超大规模云计算企业的资本支出预计在 2026 年将达到 6670 亿美元，占运营现金流的 92%。这一支出狂潮导致自由现金流收益率降至历史低位，股票回购大幅萎缩。分析认为，资本支出增速将在 2026 年下半年放缓，可能为自由现 | [Link](https://longbridge.com/en/news/276898503.md) | | AI 没有 “忠诚”！超过 10 家 OpenAI 机构股东参与 “死敌” Anthropic 最新一轮募资 | 随着 Anthropic 完成 300 亿美元融资，包括红杉资本、Founders Fund 在内的超 10 家 OpenAI 股东罕见地进行了 “双重押注”。甚至在 OpenAI 拥有董事席位的贝莱德也参与了竞对融资。面对资本的倒戈，Sa | [Link](https://longbridge.com/en/news/276663750.md) | | CoreWeave 接近达成 85 亿美元 “AI 芯片 +Meta 合同” 担保融资 | AI 云计算公司 CoreWeave 正在寻求 85 亿美元的债务融资，以巩固其在 AI 基础设施市场的地位。融资将以 AI 芯片和与 Meta 的云服务合同作为抵押，预计利率约为 6%。此次融资有望获得 A-评级，标志着公司信用认可度提升 | [Link](https://longbridge.com/en/news/276915771.md) | | 美银调查：AI 泡沫首成信用市场头号风险，23% 投资级投资者视为最大隐患 | 美国银行最新调查显示，“AI 泡沫” 首次成为信用投资者最担忧的风险，23% 的投资级受访者将其列为首要隐患，较去年 12 月大幅上升。市场对 AI 公司投资与估值过快飙升的担忧，已超过信用市场泡沫、贸易摩擦和全球衰退等传统风险。 | [Link](https://longbridge.com/en/news/276792670.md) | | 马年首家！盛合晶微 IPO 过会 | 盛合晶微半导体有限公司于 2 月 24 日成功通过上交所上市审核，成为马年首家科创板过会企业，拟募资 48 亿元。公司专注于集成电路晶圆级先进封测，致力于支持高性能芯片，尤其是 GPU、CPU 和 AI 芯片。此次 IPO 资金将用于三维多 | [Link](https://longbridge.com/en/news/276719832.md) | --- > **Disclaimer**: This article is for reference only and does not constitute any investment advice.
