Alphabet Inc Class CAlphabet achieved Rule of 40 on operating and profit margins, indicating strong profitability and efficiency.

Berkshire Hathaway CEO Greg Abel has invested more than $20 billion into Alphabet, making it the fourth-largest position in the conglomerate's portfolio. Alphabet achieved the Rule of 40 when using operating margin and profit margin, with operating margin reaching 55% and profit margin hitting 76% in the first quarter of 2026. However, the company fell short when applying free-cash-flow margin, which declined to 28% in the same period, reflecting heavy capital expenditures on AI infrastructure projected at $180 billion to $190 billion this year. The Rule of 40 combines revenue growth and a profitability metric, and Alphabet's 19% first-quarter revenue growth helped it clear the threshold on two of three measures. Analysts caution that a future failure on operating or profit margins could signal overspending on AI.
