TriNet Group (TNET) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and TriNet published the results on October 29, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. TriNet reports EPS two ways: GAAP, under the accounting rules every US filer follows, and Adjusted Net Income per share - diluted, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• TriNet's total revenues include interest income it earns on client funds and its own cash ($13 million in Q3 2026), alongside professional service and insurance service revenues.

How TriNet 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.

• TriNet's Professional service revenues revenue was $157 million in Q3 2026, down 7% from $169 million in Q3 2025, 13% of total revenue.
• TriNet's Insurance service revenues revenue was $1.0 billion in Q3 2026, down 4% from $1.0 billion in Q3 2025, 86% of total revenue.
• TriNet's Interest income revenue was $13.0 million in Q3 2026, down 24% from $17.0 million in Q3 2025, 1% 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

TriNet's guidance table for full-year 2026 gives total revenues of $4,750 million to $4,900 million, professional service revenues of $647 million to $663 million, an insurance cost ratio of 89.5% to 88.5%, an Adjusted EBITDA margin of 8.5% to 9.0%, diluted net income per share of $2.85 to $3.35 and Adjusted Net Income per diluted share of $4.50 to $5.10.

In its Q3 2026 release, TriNet said:

“In addition to announcing our third quarter 2026 results, we are reaffirming our full-year 2026 guidance and expect to be at the high end of our earnings per diluted share range.”

• Q3 2026 (this page), reported Oct 29, 2026

TriNet is a professional employer organization (PEO): it co-employs the staff of small and medium-size businesses and provides benefits, payroll and HR services. Most of its revenue passes through insurance. In Q3 2026 insurance service revenues were $1,005 million of the $1,175 million total, professional service revenues $157 million and interest income $13 million. (TriNet Q3 2026 release, Oct 29, 2026; TriNet Form 10-K, 2025, Feb 12, 2026)

Insurance service revenues are the insurance-related billings and administrative fees TriNet collects from PEO clients and withholds from worksite employee payroll for health benefits and workers' compensation insurance provided by third-party carriers. Professional service revenues are billed mainly as a fee per worksite employee or ASO user per month. Of the $157 million, PEO services brought in $151 million and ASO services $6 million. (TriNet Form 10-Q, Q3 2026, Oct 29, 2026)

TriNet's total revenues fell 5% from $1,232 million. The 10-Q attributes the drop mainly to fewer co-employed worksite employees, partly offset by higher rates. Average worksite employees fell 12% to 296,372, and TriNet traces the decline mainly to its Technology and Professional Services verticals, partly because of repricing of its health benefits services. (TriNet Q3 2026 release, Oct 29, 2026; TriNet Form 10-Q, Q3 2026, Oct 29, 2026)

Professional service revenues fell 7%, from $169 million. Along with fewer worksite employees, TriNet cites lower ASO revenue as it winds down its former HRIS services product and migrates those clients to ASO services. Its targeted verticals are technology, financial services, life sciences, nonprofit, professional services and main street. (TriNet Q3 2026 release, Oct 29, 2026; TriNet Form 10-Q, Q3 2026, Oct 29, 2026; TriNet Form 10-K, 2025, Feb 12, 2026)

TriNet earned $0.65 per diluted share on a GAAP basis in Q3 2026, down from $0.70. Net income was $31 million against $34 million. Insurance costs fell to $894 million from $943 million, but the drop in revenue was larger. (TriNet Q3 2026 release, Oct 29, 2026)

TriNet's Adjusted Net Income per diluted share was $0.94, against $1.11. The adjusted figure adds back stock based compensation ($17 million), amortization of acquired intangible assets ($3 million) and non-cash interest expense ($1 million), and applies a non-GAAP effective tax rate of 25.5% for 2026. (TriNet Q3 2026 release, Oct 29, 2026)

Diluted weighted average shares were 47 million, against 48 million a year earlier. Over the first nine months of 2026 TriNet repurchased 2,069,650 shares for about $94 million, with about $311 million left under its authorizations, and paid a dividend of $0.29 per share in April, July and October. (TriNet Q3 2026 release, Oct 29, 2026; TriNet Form 10-Q, Q3 2026, Oct 29, 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.

TriNet gives a full-year guidance table in each release. With Q3 2026 results it reaffirmed full-year 2026 guidance of total revenues of $4,750 million to $4,900 million and diluted net income per share of $2.85 to $3.35, and said it expects to be at the high end of its EPS range. Adjusted Net Income per diluted share guidance is $4.50 to $5.10. (TriNet Q3 2026 release, Oct 29, 2026)

The same table gives an insurance cost ratio of 89.5% to 88.5% and an Adjusted EBITDA margin of 8.5% to 9.0% for 2026. Year to date the insurance cost ratio was 86%, which the 10-Q says included lower than expected claims development and a one time recovery of $21 million of prior-year costs in the second quarter.

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

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