Tenable Holdings (TENB) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Tenable published the results on October 28, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Tenable 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.

• Tenable reports in thousands of dollars; figures here are converted to millions. Tenable operates as one operating segment.
• In September 2026 Tenable issued $800.0 million of 0.25% convertible senior notes due 2031, repaid its term loan and used $170.5 million of the proceeds to buy back 5.3 million shares.

How Tenable 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.

• Tenable's Subscription revenue revenue was $255 million in Q3 2026, up 10% from $232 million in Q3 2025, 92% of total revenue.
• Tenable's Perpetual license and maintenance revenue revenue was $9.7 million in Q3 2026, down 12% from $11.1 million in Q3 2025, 4% of total revenue.
• Tenable's Professional services and other revenue revenue was $12.1 million in Q3 2026, up 32% from $9.1 million in Q3 2025, 4% 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.

This is the company's own guidance as of Oct 28, 2026, quoted as given. Walnut does not make forecasts of its own. Analyst estimates for the coming quarters are on the TENB forecast page.

GAAP revenue and diluted earnings (loss) per share, each as first reported in that quarter's release.

We do not hold a confirmed date for Tenable's next report. Companies post the date on their investor relations site a few weeks ahead, usually with the time of the conference call.

Each quarter keeps its own page with the figures as reported, so a link to one stays pointed at the same numbers after the next report.

• Q3 2026 (this page), reported Oct 28, 2026

Tenable sells exposure management software, led by its Tenable One platform, and almost all of it on subscription. Subscription revenue was $254.6 million of $276.4 million total revenue in Q3 2026, up 10%. Perpetual license and maintenance revenue fell 12% to $9.7 million, and professional services and other revenue rose 32% to $12.1 million. (Tenable Form 10-Q, Q3 2026, Nov 3, 2026)

The 10-Q puts the increase down to existing customers: revenue from customers Tenable had as of October 1, 2025 rose $25.6 million, partly offset by a $1.7 million decrease in revenue from new customers. Tenable added 413 new enterprise platform customers in the quarter, against 437 a year earlier. (Tenable Form 10-Q, Q3 2026, Nov 3, 2026)

Tenable sells almost entirely through a two-tier channel of distributors and resellers, which brought in 95% of revenue in Q3 2026. One distributor accounted for 29% of revenue, against 32% a year earlier, and 23% of accounts receivable at September 30, 2026. (Tenable Form 10-Q, Q3 2026, Nov 3, 2026)

By region, the Americas brought in $166.1 million, Europe, Middle East and Africa $77.6 million and Asia Pacific $32.7 million. Customers in the United States accounted for 52% of revenue. U.S. revenue rose 7% and international revenue 12%. Tenable says its third quarter is seasonally strong because of U.S. government and related agencies. (Tenable Form 10-Q, Q3 2026, Nov 3, 2026)

Tenable's GAAP diluted EPS was $0.10 in Q3 2026, against $0.02 a year earlier, and its non-GAAP EPS was $0.63, against $0.42. Most of the gap is stock-based compensation, $51.2 million in the quarter, or $0.44 per share. Non-GAAP net income also excludes amortization of acquired intangible assets ($6.8 million), a $2.6 million loss on extinguishment of debt, restructuring and acquisition-related expenses. (Tenable Q3 2026 release, Oct 28, 2026)

Buybacks cut Tenable's share count. It repurchased 6.8 million shares for $223.8 million in Q3 2026, including 5.3 million shares for $170.5 million bought with proceeds of its convertible senior notes, and diluted weighted-average shares fell to 115,970 thousand from 121,953 thousand. Since 2023 it has bought back 28.8 million shares for $816.2 million. (Tenable Q3 2026 release, Oct 28, 2026; Tenable Form 10-Q, Q3 2026, Nov 3, 2026)

Tenable recorded a $0.5 million income tax benefit in the quarter, against a $0.6 million provision a year earlier, and GAAP operating margin rose to 6.0% from 2.8%. (Tenable Q3 2026 release, Oct 28, 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.

Tenable publishes a numeric outlook in each release. For Q4 2026 it guided revenue of $277.0 million to $280.0 million and non-GAAP EPS of $0.56 to $0.58 on 114.0 million diluted shares. For full year 2026 it raised revenue to $1.084 billion to $1.087 billion and guided non-GAAP EPS of $2.16 to $2.19 and unlevered free cash flow of $289.0 million to $295.0 million.

A consensus figure is the average of the models published by the analysts who cover Tenable, 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 Tenable'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 TENB is on is TENB a buy or a sell?, what analysts expect next is on the TENB forecast, and what the company does is on the Tenable Holdings (TENB) stock page.

Every number on this page can be traced to a document Tenable 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.
