Perimeter Solutions (PRM) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Perimeter Group 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. Perimeter Group reports EPS two ways: GAAP, under the accounting rules every US filer follows, and Adjusted EPS (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.

• Perimeter Solutions, Inc. changed its name to Perimeter Group Inc. with this release; the PRM ticker is unchanged.
• GAAP results swing with the founders advisory fee, a liability whose fair value moves with Perimeter's share price. Q3 2026 carried a $239.5 million credit from it and Q3 2025 a $247.7 million charge. Perimeter excludes it from Adjusted EPS.
• Perimeter lists seasonality among the risks to its results. In the history below, the two third quarters have the highest net sales of the five.

How Perimeter Group 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.

• Perimeter Group's Fire Safety revenue was $313 million in Q3 2026, up 14% from $273 million in Q3 2025, 80% of total revenue.
• Perimeter Group's Specialty Products revenue was $77.3 million in Q3 2026, up 84% from $42.0 million in Q3 2025, 20% 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.

Revenue and diluted EPS for the last 5 quarters. Each date links to that quarter's release.

GAAP net sales and diluted EPS, each as first reported in that quarter's release. Quarterly GAAP EPS moves with the founders advisory fee, which is remeasured each quarter with Perimeter's share price.

We do not hold a confirmed date for Perimeter Group'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 Nov 5, 2026

Perimeter Group's net sales rose 24% to $389.9 million in Q3 2026 from $315.4 million. Fire Safety, which includes the aerial fire retardant business, was $312.6 million, up 14%, and Specialty Products was $77.3 million, up 84%. Perimeter describes itself as six businesses across two segments: Perimeter Solutions, Solberg Fire and Monaco Enterprises in Fire Safety, and Phosphorus Derivatives, Medical Manufacturing Technologies and Intelligent Manufacturing Solutions in Specialty Products. (Perimeter Group Q3 2026 release, Nov 5, 2026)

Fire Safety net sales rose $39.2 million. The 10-Q splits that into $25.9 million more from fire retardant, up $14.6 million in North America and $11.3 million in other geographies, and $13.3 million more from other fire businesses, including $5.5 million from a recently acquired business. Perimeter bought Monaco Enterprises on July 30, 2026 for $117.1 million net of cash. (Perimeter Group Form 10-Q, Q3 2026, Nov 5, 2026; Perimeter Group Q3 2026 release, Nov 5, 2026)

Specialty Products net sales rose $35.2 million, made up of a $40.6 million increase from recently acquired businesses and a $5.4 million decline in base businesses because of supply disruptions. Perimeter counts an acquired business as base only after four full quarters of ownership. (Perimeter Group Form 10-Q, Q3 2026, Nov 5, 2026)

Perimeter depends on U.S. government firefighting agencies. In 2025 the USDA Forest Service accounted for 32% of consolidated revenues and the U.S. Bureau of Land Management for 11%, and no other customer reached 10%. (Perimeter Solutions Form 10-K, 2025, Feb 26, 2026)

Perimeter Group's diluted EPS was $1.74 against a loss of $0.62 a year earlier, while Adjusted EPS rose to $0.85 from $0.82. The founders advisory fee accounts for most of the gap. Its fair value fell by $239.5 million in Q3 2026 because of a lower fair value of Perimeter's common stock; a year earlier it rose by $247.7 million and produced a charge. (Perimeter Group Q3 2026 release, Nov 5, 2026; Perimeter Group Form 10-Q, Q3 2026, Nov 5, 2026)

Adjusted net income of $144.3 million adds back amortization ($24.8 million), acquisition costs ($6.0 million), stock-based compensation ($4.4 million) and a $3.7 million inventory step-up from purchase accounting, net of a $37.4 million tax impact. Income tax expense on the GAAP line was $90.9 million. (Perimeter Group Q3 2026 release, Nov 5, 2026)

Diluted shares were 174,956,402 for GAAP EPS and 170,242,280 for Adjusted EPS, against 153,660,528 adjusted shares a year earlier. Interest expense rose to $20.4 million from $9.9 million, which the 10-Q puts down to higher average debt after Perimeter's offering of its 2034 Notes in January 2026. (Perimeter Group Q3 2026 release, Nov 5, 2026; Perimeter Group Form 10-Q, Q3 2026, 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.

Perimeter Group's Q3 2026 release does not include a revenue or earnings outlook for Q4 2026 or the full year. The release reports results, capital allocation and the Monaco acquisition, and gives no numeric guidance. (Perimeter Group Q3 2026 release, Nov 5, 2026)

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

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