Perimeter Group (PRM) Q3 2026 earnings review
Perimeter Group operating profit rises 20%, but dilution slows per-share gains
Perimeter Group, the maker of wildfire retardant and niche industrial equipment, restored its firefighting profit margin while higher debt costs and share dilution held back per-share earnings. Third-quarter sales rose 24% from a year ago to $390 million and Adjusted EBITDA climbed 20% to $224 million, as Fire Safety profit rebounded from a second-quarter dip. Yet profit per share excluding one-offs grew only 4% because interest bills doubled and the share count expanded.
| Revenue | $389.9M +24% from a year ago |
|---|---|
| Fire Safety Adjusted EBITDA | $201.6M +14% from a year ago (65% margin) |
| Specialty Products Adjusted EBITDA | $21.9M -18% from last quarter (+140% from a year ago) |
| Profit per share, excluding one-offs | $0.85 +4% from a year ago ($0.82) |
⚖️ Verdict: 🟢 Bullish
The story got better because the core Fire Safety unit proved its second-quarter slowdown was temporary, growing profit 14% against its toughest comparison of the year and restoring its 65% profit margin. One caution: Specialty Products sales and profit fell from the second quarter, and by our math underlying Specialty sales barely moved once the January medical equipment acquisition is stripped out.
The question now is whether the acquisition spree creates per-share value faster than debt interest and founder fee dilution eat it up. Either the newly acquired businesses grow profit without needing more debt and stock issuance, or financing and advisory costs keep capturing most of the operating gains. The third-quarter filing's organic sales breakdown and the early-2027 founder fee settlement will tell.
🐂 Bull Case
Fire Safety Margin Rebounded to 64.5%
Fire Safety, which sells wildfire retardant and firefighting foam, had a weak second quarter when a federal price cut and a pause in defense foam orders held profit growth to 1%. Management said then that California pricing and resumed foam deliveries would restore profitability in the second half. Third-quarter results backed that up against the toughest comparison of the year.
Segment sales rose 14.3% from a year ago to $312.6 million, and Adjusted EBITDA (operating profit before interest, taxes, depreciation, amortization, and one-offs) climbed 13.8% to $201.6 million. By our math, even after stripping out an estimated $5.2 million of two-month sales from Monaco Enterprises (acquired July 30), underlying sales grew about 12.5%. Segment Adjusted EBITDA margin reached 64.5%, rebounding from 60.9% last quarter and matching the 64.8% level from a year ago.
What to watch: the revenue split between underlying firefighting sales and the newly acquired Monaco business in the quarterly filing. A double-digit underlying gain would confirm that defense foam shipments and state retardant pricing have overcome the federal price step-down.
Six-Business Model Doubled Specialty Profit
Perimeter Group is using acquisitions to expand beyond wildfire retardant into six niche industrial businesses across two segments. It bought Medical Manufacturing Technologies (MMT), a maker of medical device assembly equipment, in January, and closed the purchase of Monaco Enterprises, a provider of military base fire alarm systems, on July 30 for $117.1 million in cash.
The company said "Continued Value Driver execution and recent acquisitions drove third quarter Adjusted EBITDA of $223.5M". In Specialty Products, which houses MMT alongside phosphorus chemicals and circuit-board assembly, sales jumped 83.8% from a year ago to $77.3 million and Adjusted EBITDA rose 140.5% to $21.9 million. That lifted the segment's profit margin to 28.3% from 21.7% a year earlier, when plant downtime hurt results.
What to watch: Monaco's standalone revenue and profit contribution inside the Fire Safety segment in the third-quarter filing. A profit margin near or above the 35% level management targeted at acquisition would validate the deal playbook.
Positives this quarter didn't test
Two multi-year growth drivers in the wildfire business had no separate figures in the third-quarter earnings release.
- Global air tanker fleet expansion: Canada, Texas, and European governments are adding retardant-dropping aircraft, and updates on airbase builds on the conference call will show the pace of capacity additions.
- Fixed service revenue baseline: five-year contracts with federal and California agencies shifted more revenue to fixed fees, and the fourth-quarter off-season results will test how well those fees support off-peak profit.
🐻 Bear Case
Debt Costs and Dilution Kept EPS Growth to 4%
Perimeter Group aims for "driving private-equity-like returns, all enabled by its Operational Value Drivers model and decentralized operating structure". While total revenue climbed 23.6% from a year ago and Adjusted EBITDA grew 20.0% to $223.5 million, almost none of that operating growth reached shareholders on a per-share basis. Profit per share excluding one-offs rose 3.7%, from $0.82 to $0.85.
- Net interest expense: $20.4 million, up 106.4% from $9.9 million a year ago after issuing $550 million of debt for acquisitions
- Diluted shares for Adjusted EPS: 170.2 million, up 10.8% from 153.7 million a year ago after issuing stock for founder advisory fees
- Founder advisory fee liability: $391.1 million on the balance sheet ($61.4 million current and $329.7 million non-current), after a $239.5 million non-cash accounting gain this quarter
- Net debt: $1.10 billion, or 2.7 times trailing 12-month Adjusted EBITDA by our math, up from 1.0 times a year ago
The gap matters because buying businesses with debt while paying founder fees in stock taxes per-share growth from both sides. Higher interest bills eat into operating profit, and the larger share count divides what is left among more shares.
What to watch: the year-end founder advisory fee liability and share settlement due in the first quarter of 2027. A large stock and cash payout would further dilute shareholders and drain cash needed to pay down debt.
Specialty Products Slowed From Last Quarter
The company says it expects to "grow organically and through value-creating acquisitions", but the third-quarter numbers in Specialty Products show growth is still coming almost entirely from deals. While segment sales rose 83.8% from a year ago, they fell 8.8% from the second quarter ($77.3 million vs $84.7 million), and segment Adjusted EBITDA dropped 18.4% from last quarter to $21.9 million.
At the time of the MMT acquisition, the company cited standalone annual sales of about $140 million, or $35 million a quarter. By our math, subtracting $35 million from third-quarter segment sales leaves $42.3 million, up 0.6% from $42.1 million a year ago. Meanwhile, the phosphorus chemical business continues to face "litigation costs arising from a contractual dispute" over its supplier-operated Sauget plant ($1.0 million in Q3, $2.4 million year-to-date). Consolidated gross margin also dipped 2.0 percentage points from a year ago to 61.1%, as cost of goods sold rose to 38.9% of revenue (including a $3.7 million accounting charge on acquired inventory) and mix shifted toward lower-margin Specialty sales.
What to watch: the breakdown between acquired and existing business sales in the third-quarter filing. A third straight decline in existing Specialty sales would show the chemical plant dispute is still offsetting growth elsewhere.
Risks this quarter didn't answer
Four standing operational and legal risks were not updated in the third-quarter press release.
- Sauget chemical plant supply plan: management previously promised action to end its reliance on the disputed Flexsys plant, and the conference call or filing will show if it has committed capital or a timeline.
- Defense foam contract delivery pace: the release did not size quarterly revenue from the five-year Defense Logistics Agency foam contract, which the filing's revenue footnote or call remarks may clarify.
- Existing vs acquired Specialty revenue: the exact dollar split between MMT and the older Specialty businesses awaits the filing's management discussion table.
- Firefighting foam lawsuits: multi-district litigation over legacy aqueous film-forming foam (AFFF) awaits the legal contingencies note in the quarterly filing.

Name Change to Perimeter Group Completed
The company "completed its name change from Perimeter Solutions, Inc." to Perimeter Group Inc. during the quarter. The new name reflects its expansion from a wildfire-retardant specialist into a parent company running 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.
💲 Other KPIs
Current deferred revenue — cash customers have paid upfront for products or services not yet delivered — stood at $16.6 million, up 72.3% from $9.6 million a year ago. It fell by $9.8 million from $26.4 million in the second quarter as the company fulfilled peak summer wildfire orders, while nine-month inflows rose to $11.6 million from $7.8 million last year.
By our math, third-quarter free cash flow (operating cash flow minus $12.7 million of capital spending) was $150.4 million, or 38.6% of sales, down 22.3% from $193.6 million a year ago. That seasonal cash inflow turned nine-month operating cash flow positive to $73.5 million, after a $95.7 million cash founder fee payout and an $86.8 million receivables build weighed on the first half.
By our math, combined goodwill ($1.43 billion) and intangible assets ($1.25 billion) reached $2.68 billion after the Monaco acquisition, up from $1.96 billion at the end of 2025. Acquisition accounting assets now make up 78.9% of Perimeter Group's $3.40 billion balance sheet, driving quarterly amortization charges up 63.0% from a year ago to $24.8 million.
❓ Key Questions
Why did Perimeter Group provide no financial outlook?
The third-quarter release included no revenue, profit, or cash flow targets for the fourth quarter or full year, and dropped the long-term modeling assumptions table. Investors need to know if the ~$75 million annual interest and $30–40 million capital spending assumptions still hold after buying Monaco.
What did existing Specialty Products businesses grow without MMT?
Specialty Products sales fell 8.8% from the second quarter to $77.3 million, and Adjusted EBITDA dropped 18.4% to $21.9 million. Because existing Specialty sales shrank by $5.5 million in the second quarter, investors need the exact third-quarter split between MMT and the older businesses.
What is the cost and timeline to replace Sauget supply?
Perimeter spent another $1.0 million in the third quarter ($2.4 million year-to-date) on litigation over the Flexsys-operated phosphorus plant in Sauget. Last quarter management said it was taking action to end its reliance on the plant, but has not shared the capital required or a completion date.
How much cash will founder fees take in early 2027?
The balance sheet still carries $391.1 million in related-party founder advisory fee payables, including $61.4 million due within 12 months. After paying $95.7 million in cash and issuing 13.4 million shares in early 2026, management has not sized the expected early-2027 cash drain.
