Porvair Targets 16%-18% Margins as Capital Markets Day Sets Growth Blueprint

Key Points

• Porvair set ambitious medium-term targets, including reported revenue growth above 10% annually, mid-single-digit organic growth, adjusted operating margins of 16%–18% by fiscal 2031, EPS growth of 10%–20% per year and cash-flow conversion of at least 85%.
• The company sees growth across its three divisions, supported by aerospace and industrial filtration demand, tighter water-testing regulations, life-sciences automation and increasing aluminum recycling. Recent investments include the GV Filtri and Drache acquisitions and a 50% expansion of U.S. filter-production capacity.
• Porvair plans to continue disciplined acquisitions while generally keeping leverage below 1.5 times EBITDA, although it may reach 2 times for a compelling deal. Management said fiscal 2026 trading had started slightly ahead of market expectations.

Porvair LON: PRV used its first capital markets event to set out a medium-term financial framework centered on faster revenue growth, higher operating margins, strong cash conversion and disciplined acquisitions.

Chief Executive Officer Hooman Javvi said the specialist filtration, laboratory and environmental technology group was at an “inflection point” after building management capabilities, completing a strategy review and increasing its focus on customer proximity, operating execution and capital allocation.

Javvi said Porvair had grown revenue from £45 million to nearly £200 million over the past two decades, while operating margins improved from 7% to 13.5%. The company has organized its operations into Aerospace and Industrial, Laboratory, and Metal Melt Quality divisions, serving niche markets including aerospace, water analysis, life sciences and aluminum production.

The CEO described the company’s strategy as “focus, deliver and compound,” combining decentralized operating businesses with stronger accountability and centralized support for strategy, capital allocation and mergers and acquisitions. Porvair said it had increased operating margin by 80 basis points to 13.5% in 2025 and sees a route to further improvement through commercial initiatives, operational improvement, portfolio management and organizational changes.

New medium-term framework

Group CFO James Mills introduced a new medium-term framework, which he said was not a forecast but represented management’s view of what the group could deliver over time.

• Total reported revenue growth of more than 10% on a compound annual basis, including acquisitions.
• Mid-single-digit organic revenue growth at constant currency.
• Adjusted operating margins of 16% to 18% by fiscal 2031, compared with 13.5% in fiscal 2025.
• Adjusted earnings-per-share growth of 10% to 20% annually.
• Operating cash-flow conversion of at least 85%.
• Leverage generally below 1.5 times, though the group may reach 2 times EBITDA for a compelling strategic transaction.

Mills said revenue grew at an 8% compound annual rate over the past five years, from £135 million to £194 million, while adjusted EPS rose at a 14% compound annual rate. He added that fourth-quarter fiscal 2026 trading had started positively and was “slightly ahead of market expectations,” according to the company’s trading update.

Porvair generated more than 90% operating cash-flow conversion in each of the past five years, Mills said. Over that period, the group generated about £85 million in free cash flow before investing £55 million in acquisitions and capital expenditure and paying £13 million in dividends.

Division growth plans

Aerospace and Industrial Managing Director Emrah Gozturk said the division generated just under £84 million of revenue in fiscal 2025. He highlighted the division’s exposure to aerospace, chemical processing, nuclear waste management, semiconductors and other demanding industrial applications.

Gozturk said Porvair components are installed on roughly two-thirds of the global civil aircraft fleet, including almost all Boeing, Airbus and COMAC aircraft. The division also supplies a patented filtration system for the Hanford nuclear-waste treatment site in Washington state, a process expected to operate for approximately 50 years.

The division recently acquired Italian filtration business GV Filtri, which generated about €5 million in revenue in its last year. Porvair plans to use the Turin-based company as a hub for Southern Europe and to expand its reach into other geographies.

Laboratory Division Director Mark Osborne said the division serves life-sciences and environmental-testing markets through instruments, specialist consumables and automation equipment. The company is combining four life-sciences businesses into a single operating company with five sites, aiming to improve commercial coordination, product development and customer service.

SEAL Analytical President Lalicia Potter said rising regulatory requirements for water and soil testing were supporting demand for automated analytical instruments. She said SEAL’s AQ700 analyzer helped a global laboratory group increase sample throughput and productivity by 400% while reducing labor costs. The systems also create recurring revenues from proprietary consumables, training and support contracts.

In life sciences, R&D Manager Lindsay Parkes said Porvair is developing the Clara product range for biologics research and development. The company said the Clara 6 Well system is intended to support automation-compatible sample processing and accelerate workflows in biologics development.

Metal Melt Quality and M&A

Metal Melt Quality Managing Director Watt Jackson said demand for aluminum filtration was being supported by lightweighting in aerospace and electric vehicles, as well as increased aluminum recycling. Recycling requires less energy than primary aluminum production but can create higher levels of inclusions in molten metal, increasing filtration needs, he said.

Porvair acquired Drache, a German metal-filtration specialist, in January for about £17 million net. Drache reported revenue of approximately €20 million in 2025. Mills said Porvair expects to deliver more than £1 million of synergies in the first 24 to 36 months of ownership through commercial, purchasing and operational initiatives.

Jackson said Porvair also invested £5 million to increase firing capacity at a U.S. casthouse filter production line by 50%. The new kiln entered service earlier in 2026, on time and on budget, he said.

Javvi said the group has deployed around £90 million across 18 acquisitions since 2012. During 2026, Porvair deployed £25 million across three deals, compared with a long-term average of about £5 million and one transaction annually. Management said it had sourced more than 250 potential opportunities but declined more than 70 over the past 18 months because they did not meet its strategic or financial requirements.

“We are ambitious on value, but we remain disciplined on price,” Javvi said, adding that acquisitions would be assessed on strategic fit, financial quality and the potential to improve the acquired business under Porvair ownership.
