Five9 Stock Plunges 20% Despite Beat — Guidance Cut Spooks Market

Five9 stock plunged about 20% after hours on Thursday, November 5, 2026, even though the cloud contact-center company beat earnings and revenue estimates — because it lowered its full-year profit guidance and announced a $325 million acquisition on the same night. Shares fell 19.8% immediately after the release to $27.40, according to StockStory, after closing the regular session at $34.14, down 6.1% in the day's broad tech selloff. After-hours trackers later showed the stock around $27.77, down about 19%, making Five9 one of the session's biggest losers alongside DraftKings.

What happened

Five9 reported third-quarter 2026 results after the close for the quarter ended September 30. Revenue rose 13.1% year on year to $323.3 million, ahead of the $319.2 million consensus cited by StockStory and the Zacks consensus it also beat. Non-GAAP earnings were $0.82 per share, above the $0.80 consensus — a 2.5% surprise on Zacks' measure and the company's fourth straight EPS beat. Subscription revenue grew 16% year on year, billings rose 14.8% to $335.7 million, and the last-twelve-months subscription dollar-based retention rate was 109%.

On a GAAP basis the picture was softer: net income was $14.5 million, or $0.19 per share, down from $18.0 million, or $0.21, a year earlier, and gross margin slipped to 53.4% from 55.0%. Non-GAAP net income was $63.7 million, or $0.82. The quarter itself was solid — the problem was the outlook.

Why the stock fell anyway

The selloff was about what comes next, not what just happened. Five9 guided fourth-quarter revenue to about $331 million at the midpoint, roughly in line with expectations, but it lowered its full-year adjusted EPS guidance to $3.19 at the midpoint, a 2.1% cut that left both the next-quarter and full-year profit outlooks short of Wall Street consensus. In a market that punished guidance misses on Thursday — the Nasdaq fell 5.5% into correction — that triggered a sharp repricing.

The second factor was the deal announced alongside earnings. Five9 signed a definitive agreement to acquire Level AI for $325.0 million in cash. StockMarketWatch noted the soft revenue outlook overshadowed the acquisition news in the first reaction, and investors were left to weigh a large cash outlay against a trimmed profit forecast on a day when risk appetite was already thin. Five9 presents the move as part of its Genius CX Platform and AI push — management highlighted accelerating subscription growth and a significant step-up in AI revenue growth — but the market's immediate verdict was to focus on cost and guidance, not strategy.

Why it's blowing up

Five9 became a textbook example of Thursday's pattern: beat the quarter, lose on the outlook. DraftKings cratered on a weak forecast the same evening, while JFrog and Cloudflare surged after raising guidance. Five9's drop stood out because its quarter showed no revenue miss at all — double-digit growth and a beat, yet a fifth of its value gone in minutes.

Five9 shares had also run up strongly during 2026, so expectations were elevated — a guidance trim plus a $325 million cash deal was bound to reprice fast on a day already selling software names.

What's next

Investors will now look for detail on how the Level AI deal affects spending and margins, and whether the lowered EPS path reflects conservatism or slower demand. The next checkpoint is the fourth-quarter report, where the $331 million revenue guide will be tested — and whether subscription and AI growth can offset GAAP margin pressure. This report describes what happened and why markets reacted; it is not a recommendation to buy, sell, or hold any security.
