Alphabet's AI Push Weighs on Cash Conversion
Alphabet, the parent company of Google, has been pouring massive amounts of capital into artificial intelligence to strengthen its position in the AI race. Its strong returns on invested capital (ROIC) are a testament to the high-quality business it has built.
The company's trailing-12-month ROIC is 40.36%, more than double its 10-year median of 20.3% and above the 20% industry median. Google Search & other revenues rose 17% year over year to $63.27 billion in the second quarter of 2026, while YouTube advertising revenues increased 13% to $11.06 billion.
Google Cloud revenues surged 82% to $24.77 billion, with operating margin expanding to 35.6% from 20.7%. The cloud business has a substantial runway, with backlog reaching $514 billion. Meanwhile, Gemini adoption and Alphabet's broader AI stack are creating additional opportunities across Search, enterprise software, infrastructure, and security.
Alphabet also scores well on earnings consistency, surpassing estimates in the trailing four quarters. However, the company's cash conversion problem is a concern. Its TTM cash-flow conversion is 76.1%, below its 105.8% median, while FCF conversion is only 21.8% versus a 43% median.
The deterioration largely reflects the enormous resources being committed to AI infrastructure and related working-capital requirements. Management has raised 2026 capital-expenditure guidance to $195-$205 billion and expects spending to increase significantly again in 2027. This is an industry-wide arms race, with Amazon lifting its 2026 capex target to $220 billion and Microsoft expecting roughly $175 billion in fiscal 2027 capex.
