  • Second-quarter 2026 Revenue was $183.3 million, up 23% year on year, with Security revenue up 43%.

A Comcast edge deployment

Fastly Inc. (NASDAQ:FSLY) and Comcast announced a Partnership on 10 September 2026 under which Fastly's programmable edge software is embedded in Comcast's edge compute platform, across more than 200 AI-powered edge compute centres in its network. The aim is to store and deliver live streaming content closer to viewers, which Comcast says reduces lag during peak demand.

The software runs on virtual cable modem termination systems and handles traffic management, real-time security, edge compute and AI services. On 28 September 2026 the two companies said the model was powering Peacock's biggest live events.

No financial terms were disclosed. The announcement described performance gains qualitatively and called results initial, so the revenue effect for Fastly cannot be judged.

Second-quarter results

Fastly reported second-quarter 2026 results on 5 August 2026. Revenue was US$183.3 million, its highest quarterly revenue to date, up 23% year on year. Network Services revenue was US$133.9 million, up 17%, Security revenue was US$41.7 million, up 43%, and other revenue was US$7.7 million, up 69%.

GAAP gross Margin was 63.3%, its highest to date, and non-GAAP gross margin was 65.8%. The GAAP net loss was US$15.6 million, or US$0.10 per share, and the GAAP operating loss narrowed to US$14.4 million. Non-GAAP Operating Income was US$27.0 million and non-GAAP Net Income US$26.2 million, or US$0.15 per diluted share.

Operating cash flow was US$39.3 million and free cash flow US$3.6 million. Remaining performance obligations rose 38% to US$341 million, and trailing twelve-month net retention improved to 117%. The top ten customers accounted for 37% of revenue, a concentration worth noting. Network Services made up about 73% of revenue and Security about 23%, so the faster-growing Security line is still the smaller one.

Guidance

For the third quarter, Fastly guided to revenue of US$184 million to US$190 million and, for the full year, revenue of US$732 million to US$746 million. It expects positive non-GAAP profitability in both periods. The midpoint of the third-quarter range, US$187 million, is about 2% above the second-quarter figure. These are management forecasts, not results.

Recent announcements and what to watch

On 13 October 2026 Fastly expanded its partnership with Jio Platforms to support JioCDN in India, and on 21 September it launched AI Firewall and AI Runtime Control.

The company will report third-quarter results after the market close on 4 November 2026, with a call at 1:30 p.m. Pacific Time. Points to follow include revenue against the guided range, Security growth relative to the 43% reported in the second quarter, and customer concentration. Net retention above 100% means existing customers expanded their spending.
