Five9 (FIVN) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Five9 published the results on November 5, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Five9 reports EPS two ways: GAAP, under the accounting rules every US filer follows, and non-GAAP, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• Five9 signed a definitive agreement to acquire Level AI for $325.0 million in cash, expected to close in Q4 2026. Its outlook excludes any contribution from the deal.
• Five9 reports one operating segment. The rows above are its revenue by geographic region based on customer billing address, from the 10-Q.

How Five9 splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• Five9's United States revenue was $287 million in Q3 2026, up 13% from $254 million in Q3 2025, 89% of total revenue.
• Five9's International revenue was $36.1 million in Q3 2026, up 13% from $32.0 million in Q3 2025, 11% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

The first two quotes are Five9's full-year 2026 outlook; the last two are its outlook for the fourth quarter of 2026. Five9 says the guidance does not include any contribution from the pending acquisition of Level AI.

In its Q3 2026 release, Five9 said:

“Revenue in the range of $1.269 to $1.275 billion.”

“Non-GAAP net income per share in the range of $3.17 to $3.21, assuming diluted shares outstanding of approximately 77.1 million.”

“Revenue in the range of $328.0 to $334.0 million.”

“Non-GAAP net income per share in the range of $0.88 to $0.92, assuming diluted shares outstanding of approximately 78.0 million.”

• Q3 2026 (this page), reported Nov 5, 2026

Five9 had revenue of $323.3 million in Q3 2026, up 13% from $285.8 million a year earlier. Five9's supplemental disclosure splits that into subscription revenue at 83% of the total, telecom (usage) revenue at 11% and professional services at 6%. Subscription's share has risen from 81% in Q3 2025, and the release headlines subscription revenue growth of 16% year over year. (Five9 Q3 2026 release (8-K Exhibit 99.1), Nov 5, 2026; Five9 supplemental metric disclosure, Q3 2026 (8-K Exhibit 99.2), Nov 5, 2026)

Five9 sells a cloud contact center platform to more than 3,000 customers. It charges monthly subscription fees mostly based on the number of licenses, sells its AI solutions on a consumption or capacity basis, and also earns usage-based telephony revenue. No single customer represented more than 10% of revenue in 2025, 2024 or 2023. (Five9 Form 10-K, 2025, Feb 20, 2026)

Five9's 10-Q says the increase in revenue was primarily attributable to its larger customers, driven by its sales and marketing activities and improved brand awareness. In the release, CEO Amit Mathradas pointed to accelerating subscription revenue growth and said AI revenue growth stepped up significantly, without giving an AI revenue figure. (Five9 Form 10-Q, Q3 2026, Nov 5, 2026; Five9 Q3 2026 release (8-K Exhibit 99.1), Nov 5, 2026)

Five9's revenue is mostly domestic. Customers billed in the United States produced $287.2 million of Q3 revenue and international customers $36.1 million. Remaining performance obligations on contracts longer than one year were $1,606 million, and Five9 expects to recognize about three-fourths of that over the next 24 months. (Five9 Form 10-Q, Q3 2026, Nov 5, 2026)

Five9 earned GAAP net income of $14.5 million, or $0.19 per diluted share, in Q3 2026, against $18.0 million, or $0.21, a year earlier. Non-GAAP net income was $63.7 million, or $0.82 per diluted share, up from $0.78. The largest adjustment between the two is stock-based compensation of $34.9 million. Five9 also adds back intangibles amortization, costs related to reduction in force plans ($4.3 million this quarter), acquisition costs and one-time advisory fees. (Five9 Q3 2026 release (8-K Exhibit 99.1), Nov 5, 2026)

Five9's diluted share count for GAAP EPS fell to 77.3 million from 87.3 million a year earlier, partly because it repurchased shares: $100.0 million of stock in the first nine months of 2026, including a $90 million accelerated share repurchase entered in May 2026. No amount remained under the 2025 Repurchase Program at September 30, 2026. (Five9 Q3 2026 release (8-K Exhibit 99.1), Nov 5, 2026; Five9 Form 10-Q, Q3 2026, Nov 5, 2026)

Five9 says its non-GAAP adjustments carry no net tax effect because of its significant net operating loss carryforwards and domestic valuation allowance. The GAAP provision for income taxes was $1.2 million in the quarter. (Five9 Q3 2026 release (8-K Exhibit 99.1), Nov 5, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Five9 publishes a numeric outlook in each release. For the fourth quarter of 2026 it expects revenue of $328.0 to $334.0 million and non-GAAP EPS of $0.88 to $0.92, and for full year 2026 revenue of $1.269 to $1.275 billion with non-GAAP EPS of $3.17 to $3.21. GAAP EPS guidance is $0.28 to $0.36 for the quarter and $0.75 to $0.83 for the year. (Five9 Q3 2026 release (8-K Exhibit 99.1), Nov 5, 2026)

The guidance excludes any contribution from Level AI, which Five9 agreed to buy for $325.0 million in cash and expects to close in Q4 2026. (Five9 Q3 2026 release (8-K Exhibit 99.1), Nov 5, 2026)

A consensus figure is the average of the models published by the analysts who cover Five9, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Five9's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning FIVN is on is FIVN a buy or a sell?, what analysts expect next is on the FIVN forecast, and what the company does is on the Five9 (FIVN) stock page.

Every number on this page can be traced to a document Five9 published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
