Akamai Q3 2026: Six EPS Beats, But Capex Doubles the Concern

Akamai posted adjusted earnings of $1.77 per share in Q3 2026, beating the consensus estimate of $1.67 and extending its streak of beats to six consecutive quarters. Revenue of $1.12 billion rose 6.4% year over year, beating expectations, with growth led by the Security and Cloud Infrastructure Services segments.

The market's lukewarm reaction to an otherwise solid report comes down to one line item: capital expenditures jumped to 41% of revenue from 21% a year ago, a swing that reflects an aggressive infrastructure buildout running well ahead of the revenue it is meant to support. Non-GAAP operating margin compressed to 25% from 31% in the same period last year as both cost of revenue and operating expenses rose alongside that spending.

CEO Tom Leighton said the company has signed more than $14 billion worth of multi-year Cloud Infrastructure Services commitments so far in 2026, and management provided long-range targets calling for total revenue exceeding $7 billion in 2028. For Q4 2026, Akamai guided to non-GAAP EPS of $1.50 to $1.70.

The gap between today's cost and tomorrow's revenue is precisely what investors are pricing. Capital expenditures rose 210% year over year in Q3 as the company leaned on financing, including convertible senior notes issued in Q2 2026, to fund the buildout. Until the committed CIS revenue starts flowing through the income statement at scale, margin pressure remains a recurring headline.

Two new products add texture to the growth story: Akamai Inference, which lets enterprises build and tune open-weight AI models on their own data, and Akamai Agent Sandbox, designed to run AI agents within tightly controlled security boundaries. Both sit inside what Leighton described as an AI-optimized cloud platform, positioning Akamai to compete for enterprise AI infrastructure spending. How quickly that pipeline converts to signed contracts is the key variable to watch alongside the capex trajectory.
