Twilio Stock Tumbles Nearly 20% After Q4 Guidance Signals Sharp Growth Deceleration

Twilio posted a strong third quarter on October 29, beating estimates on both the top and bottom lines, but its weaker-than-expected fourth-quarter outlook triggered a sharp selloff that sent shares down roughly 19% in pre-market trading on October 30. The cloud communications company reported Q3 revenue of $1.56 billion, up 20% year over year and about 3% ahead of consensus, while non-GAAP earnings of $1.65 per share beat the consensus estimate by 13% and rose 32% from the year-ago period.

The problem for investors was the Q4 outlook. Twilio guided fourth-quarter revenue to $1.595 to $1.605 billion, implying reported growth of 17% to 17.5% but organic growth of only 11% to 12%, a step down from Q3's 16% organic growth rate. Non-GAAP operating income guidance of $300 to $310 million and non-GAAP diluted EPS of $1.48 to $1.53 both represent sequential declines from the Q3 levels, and the release offered no explicit explanation for the step-down. The dollar-based net expansion rate was 114% in Q3, up from 109% a year earlier, and free cash flow reached approximately $370 million compared with roughly $248 million a year ago, signaling healthy underlying momentum that made the conservative Q4 guidance stand out.

Despite the selloff, Twilio raised its full-year 2026 reported revenue growth target to 20% from a prior range of 18% to 18.5%, and lifted its organic revenue growth outlook to 15% from 13% to 13.5%. For the full year, the company has repurchased approximately $1.3 billion of the $2 billion buyback authorized in January 2025, with roughly $700 million remaining. Wells Fargo, which had raised its price target to $300 from $275 just one day before earnings, maintained its Overweight rating.
