[Five9](https://theinference.org/markets/companies/five9) reports on November 5, and the quarter it will discuss has a hole in it [1]. Two write-ups of the same August release disagree about the number carrying the story. [CMSWire puts second-quarter AI revenue at $39 million](https://www.cmswire.com/contact-center/what-are-contact-centers-actually-doing-with-ai/), 15% of subscription revenue, up from 9% a year earlier and growing 78% [1]. [Kalkine's read of the same release says no dollar figure was disclosed](https://kalkine.com.au/stock-analysis/technology/how-is-five9-fivn-balancing-ai-led-growth-with-margins) at all, so the claim cannot be sized from the document [2]. One of the two counted wrong, and investors find out which on Wednesday. ## The AI is real, and it is eating the margin The reported quarter is solid. Revenue of $312.4 million rose 10%, subscription revenue 14%, GAAP net income $3.4 million [2]. But the cost of the AI story sits in the gross margin: adjusted gross margin fell to 61% from 63% after Five9 temporarily added professional services staff to deploy AI customers faster than planned [1]. CEO [Amit Mathradas](https://theinference.org/markets/people/amit-mathradas) says AI revenue is accelerating even faster than subscription revenue [2]. The acceleration depends on that temporary services headcount, and the third quarter shows whether the margin drag repeats when the hiring stops [1][2]. *Chart: **Gross margin fell to 53.4% in Q2 2026, the lowest in two years** Line chart of Five9 GAAP gross margin by quarter from Q2 2024 to Q2 2026, rising to a peak near 56 percent in late 2024 and falling to 53.4 percent in Q2 2026.* *Five9 GAAP gross margin, percent of revenue, from its SEC filings. The company separately reported adjusted gross margin of 61% in Q2 2026, down from 63%, after temporary professional-services hiring to speed AI deployments.

[Contact Center Intelligence, now in public preview, connects to Five9, Cisco Webex and Avaya](https://uctoday.com/ai-context-wars-microsoft-zoom-five9-fight-to-own-your-memory) and bills through Copilot Credits [3]. Microsoft entered the [Gartner](https://theinference.org/markets/companies/gartner) contact-center Magic Quadrant as a Visionary [3] and offered roughly 60,000 staff a voluntary exit to fund the push [3]. Five9's largest Q2 deal, about $100 million with a Fortune 100 financial services company, covers the platform only, AI still to be determined [1]. ## A judge has already heard Five9's guidance before The disputes are not new ground for the company. In February [a federal judge let securities-fraud claims over Five9's 2024 revenue guidance proceed](https://www.prnewswire.com/news-releases/five9-inc-nasdaq-fivn-investor-reminder-schubert-jonckheer--kolbe-llp-investigating-possible-false-statements-following-26-stock-drop-and-key-court-ruling-302918909.html), and insiders sold over $8 million in stock during the period before the stock fell 26% [4]. Full-year guidance stands at $1.260 billion to $1.272 billion of revenue and $3.22 to $3.30 of non-GAAP earnings per share [2]. ## What the November 5 print decides Holders have done well: the stock is up 87.6% this year, and [our October 24 piece covered Voss Capital trimming 28.4% of its stake for $47 million](https://theinference.com/article/voss-capital-sold-28-4-of-its-five9-stake-for-47-million-as-the-stock-rose-87-6-this-year) into that rise [6]. Nothing in the AI-revenue dispute settles the bull or bear case on its own; what settles it is whether the number is sized and profitable. The decision rule for Wednesday's print is concrete. If Five9 puts a dollar figure on AI revenue that grows from $39 million without more services headcount, the margin story has a floor [1][2][4]. If the figure is again unsized or the gross margin drops below 61%, the acceleration is being bought, and a company already facing fraud claims over its guidance has little room to leave numbers vague [1][2][4]. ## Takeaway Wednesday's print settles the dispute: a dollar figure on AI revenue, growing from $39 million without fresh services headcount, validates the story; another unsized number or a gross margin below 61% means the acceleration is being bought. ## Sources 1.
