Reliance Worldwide Corporation Limited (“RWC”) has successfully closed on the acquisition of John Guest
Holdings Ltd.

RWC is a leading global manufacturer and supplier of premium-branded engineered water delivery, control
and optimization products and solutions for residential and commercial plumbing applications and is the
premier manufacturer in the world of brass push-to-connect (“PTC”) plumbing fittings.

John Guest is a global leader in plastic push-fit fittings and pipe with products distributed worldwide. The
company operates three purpose-built manufacturing facilities in the UK and has a well-established
international sales and distribution network. Its product portfolio services three end markets: Plumbing &
Heating, Water Quality & Fluid Dispense and Industrial PTC. Its portfolio of well recognized brands includes
JG John Guest®, Speedfit®, JG ProLock™, and POLAR CLEAN®.

The acquisition of John Guest is a strong strategic fit and aligns with RWC’s strategy to add complementary
products which broaden the solutions offered to end users and expand its market presence, particularly in
Europe. The combined business will provide an end-to-end solution with applications from meter to fixture
and floor to ceiling from a single manufacturer. The combined product offering will serve to improve end
user efficiency by reducing installation times, improve reliability and durability.

Heath Sharp, RWC Chief Executive Officer, said: “We are excited to bring these two great companies
together. Our team is genuinely impressed with John Guest’s people and the culture within the
organization. The company comes with a long history of innovation and industry leading execution. John
Guest has created strong, well-respected brands that are highly regarded in their key markets globally.
They bring innovative, clever products that we believe we can successfully leverage through our wellestablished
international distribution network.

“We see alignment between our operations, products, and markets which will bring future growth
opportunities for the combined group, particularly in the UK and continental Europe.
Together, we will be able to offer a broader depth of products, a wider range of innovative solutions, and
an enhanced ability to serve customer needs today and into the future. For now, our goal is to learn from
each other, understand how our two organizations really work, and bring together our experience, talent
and strength into a unified organisation to accelerate further growth.”
