What Plexus Holdings does
Plexus Holdings PLC is an AIM-listed (LON:POS) oil and gas engineering and services business headquartered in Walton Upon Thames, United Kingdom, with operational facilities in Aberdeen. Founded in 1986, the company has spent over 30 years developing environmental wellhead protection technology for offshore energy applications, centered on its proprietary POS-GRIP Technology — a metal interface seal designed to contain methane gas in wellheads for oil and gas operators. The technology is positioned as a differentiator for environmental wellhead protection and is the basis of the London Stock Exchange Green Economy Mark awarded to the company in 2021.
The company's commercial offering spans three product lines: the POS-GRIP wellhead sealing technology (core product), the Exact Rental Wellhead Fleet (rental equipment supporting North Sea and international growth), and a range of surface wellhead products developed for offshore energy applications under partnership agreements such as the £2.5 million Cactus Wellhead engineering programme. Plexus generates revenue through two streams: equipment sales and rental of the Exact wellhead fleet, and occasional one-time licensing arrangements such as the prior-year SLB licensing deal worth £4.1m. The go-to-market model is direct enterprise sales to oil and gas operators, with no publicly disclosed pricing and contracts secured through relationship-based engagement rather than transactional channels.
In FY2025 (year ending June 30, 2025), Plexus reported revenue of £4.48 million, down from £12.7 million in the prior year primarily because the SLB one-off licensing deal did not repeat, and a loss before tax of £3.3 million versus a £2.8 million profit the prior year. The company funded expansion through a £3.5 million share placing in April 2025 and a £2 million loan facility from OFM Holdings Ltd in December 2025, and is targeting growth in the North Sea, Middle East, and North America. Headcount is in the 11-50 range and the company is led by CEO Craig Hendrie.

Plexus Holdings competitors and assessment
Company assessmentBroad incumbents
- Weatherford International: Large diversified oilfield services and equipment provider with a wellhead and intervention product line. Competes with Plexus across multiple geographies and rig types.
- Cameron (Schlumberger / SLB): Global incumbent in wellhead and pressure control equipment through its SLB Well Construction division. Already a Plexus licensing partner (the £4.1m SLB deal) and a structural competitor across the full wellhead stack.
- NOV (National Oilwell Varco): Largest oilfield equipment OEM globally, with a comprehensive wellhead, BOP, and surface equipment portfolio that overlaps with Plexus's POS-GRIP and Exact rental offerings.
Regional players
- Subsea 7: Subsea installation and IMR contractor operating heavily in the North Sea. Adjacent peer in Plexus's offshore wellhead ecosystem, often co-specifying wellhead equipment for offshore developments.
- Aker Solutions: Norway-headquartered subsea and offshore engineering specialist with strong North Sea presence. Comparable as an offshore wellhead-adjacent supplier, particularly relevant given Plexus's North Sea concentration.
Direct peers
- Forum Energy Technologies: Smaller-scale oilfield equipment manufacturer offering wellhead and pressure control products. Closely comparable in scale and product mix to Plexus, particularly in surface wellhead and rental equipment.
- TechnipFMC: Major integrated subsea and surface wellhead equipment supplier with comparable wellhead systems and aftermarket services. Competes head-to-head with Plexus in offshore wellhead technology and rental.
- Cactus Wellhead: US-based wellhead equipment manufacturer that is both Plexus's commercial partner (under the £2.5m surface wellhead development deal) and a direct competitor in surface wellheads for offshore and unconventional applications.
- Dril-Quip (Innovex Downhole Solutions): Pure-play wellhead systems manufacturer supplying surface and subsea wellhead equipment to offshore operators globally. Directly competes with Plexus's POS-GRIP-based wellhead offering in the same offshore drilling customer base.
Emerging players
- Helix Energy Solutions: Smaller offshore energy services player with well intervention and production equipment exposure. Thematically comparable in deploying specialized offshore equipment into the same customer base as Plexus.
