Gross margin expanded to 59.7%, up from 58.2% in FY2024 and 55.4% in FY2022 — four consecutive years of expansion. As the 10-K notes, Google Search 'helps people find information and make sense of the world' with 'trillions of searches' annually — each query served at near-zero marginal cost. Google Cloud's improving unit economics under Thomas Kurian further contributed to the margin uplift.

Operating cash flow of $164.7B covers net income of $132.2B by 1.25x — consistent with FY2024's ratio. Every dollar of reported profit is backed by $1.25 of real cash. The excess reflects depreciation on the massive and growing data center fleet plus stock-based compensation — both non-cash but standard for a company Alphabet describes as having invested 'more than $200 billion in research and development in the last five years.'

Net income surged to $132.2B, a 32% increase over FY2024's $100.1B. Net margin reached 32.8%, up from 28.6% — the highest in Alphabet's history. Revenue growth of 15% coupled with operating leverage on the 'AI-first' platform produced outsized profit expansion.

OCF reached $164.7B, up 31% from FY2024's $125.3B. Alphabet generates more operating cash flow than the GDP of most countries. This cash engine funds the AI infrastructure arms race — the filing highlights the company's 'AI-optimized infrastructure' as 'a key differentiator enabling us to power our own products and support Google Cloud customers.'

Revenue grew 15.1% to $402.8B — crossing the $400B threshold for the first time. For a company of this scale to sustain mid-teens growth is exceptional. The filing notes Alphabet's three segments — Google Services (Search, YouTube), Google Cloud, and Other Bets — with 'centralized AI-related research and development focused on advanced research in AI and developing the frontier models.'

ROE climbed to 31.8% from 30.8% in FY2024 — achieved with a debt ratio of only 30.2%. When ROE expands without leverage, it signals genuine competitive advantage. As the 10-K states, Alphabet's mission to 'organize the world's information and make it universally accessible and useful is as relevant today as it was when we were founded in 1998' — and that sustained relevance translates into exceptional returns on capital.

Four consecutive years of gross margin expansion (55.4% -> 56.6% -> 58.2% -> 59.7%) is the strongest signal of a widening moat in big tech. In advertising, this reflects pricing power as Google Search maintains dominance with 'trillions of searches' annually. YouTube's connected TV shift and Google Cloud's margin improvement both contribute.

The filing highlights Alphabet's 'full-stack approach' spanning 'AI-optimized infrastructure, world-class research including models and tooling, and products and platforms that bring AI to billions.' The seventh-generation TPU Ironwood and Gemini 3 — described as 'our most intelligent AI model yet' with 'enhanced reasoning capabilities' — create a vertically integrated AI stack that competitors cannot easily replicate.

Google controls ~90% of global search, ~75% of mobile OS (Android), YouTube holds ~25% of US streaming watch time, and Cloud is the fast-growing #3 provider. The filing describes Alphabet as 'a collection of businesses' where each benefits from 'strong leaders and independence' — a structure that preserves competitive focus across each platform while sharing AI infrastructure.

FCF of $73.3B is still enormous in absolute terms — larger than most S&P 500 companies' total revenue. However, it is barely up from FY2024's $72.8B despite a 31% increase in OCF, meaning virtually all incremental cash generation was consumed by AI capex. The 10-K notes the company's range of 'AI accelerator options, including specialized GPUs and our own custom-built TPUs' — all requiring massive capital deployment.

Alphabet continued its inaugural dividend program and aggressive share buybacks in FY2025. Despite the ~$91B capex bill, the company still generates enough FCF ($73.3B) to fund meaningful capital returns. The 10-K highlights the company's R&D investment of 'more than $200 billion in the last five years' — yet there is still cash left for shareholders.

Debt ratio at 30.2%, up modestly from FY2024's 27.8%, but still fortress-level. The slight increase likely reflects incremental borrowing to co-fund the massive AI capex program. With $164.7B in annual OCF, Alphabet has virtually zero insolvency risk regardless of how aggressively it invests.

Goodwill at 5.6% of total assets — down from FY2024's 7.1% as total assets grew faster than acquisitions. This reflects disciplined M&A strategy. Alphabet continues to build rather than buy its AI capabilities, avoiding the goodwill-inflating megadeals common in tech.
