Spirax Group is the new name for
Spirax-Sarco Engineering.
It balances our history and where we have
come from with who we are today, and is a
natural evolution for our Company.
Spirax Group is different but also familiar. Its simplicity aims
to create clarity, by representing everyone and everything
that we do and eliminating the confusion between the name
of our Group and the Spirax Sarco Division that provides
steam thermal solutions to customers. As Spirax Group,
we are staying true to our heritage while also reflecting our
evolution to a much larger and stronger organisation.
We are inviting our shareholders to support our legal name
change to Spirax Group plc at our AGM in May.

...supports our bright future
As a Company established during
the second industrial revolution,
anticipating and investing in our
future needs has become a core
part of our DNA.
There were lots of examples of this
during the last decade as we evolved
the scale and composition of our
Group by focusing on opportunities
to create significant value for all our
stakeholders and address the
imperative of climate change.
Engineering
our future
for over
135 years
Spirax Group is today represented by three strong
and aligned Businesses providing mission critical
thermal energy and fluid technology solutions to
industrial customers across a diverse range of sectors.
As Spirax Group we can help everyone better
understand who we are and how we work together
across our Businesses to help customers meet their
operational, sustainability and decarbonisation goals.
Throughout this report we share some of the ways
in which important decisions taken during the last
decade will continue to shape our long-term,
sustainable future.

Recent appointments improving
gender balance of Executive Team
Our financial results in 2023 were impacted by a
more challenging trading environment than we
had anticipated at the start of the year, with a
number of external headwinds to our highest
margin businesses. An early focus on restructuring
to right-size capacity, together with cost
containment actions, supported our adjusted
operating profit margin. We are well positioned
to return to revenue and profit growth in 2024.

Oil & Gas Chemicals Power Generation
6% of Group revenue
Electrical heating products reduce fluid
viscosity, deliver freeze protection and
provide efficiency in the processing of
natural gas, crude oil and water. Our steam
products enable optimum steam system
performance and reduce energy use during
oil and gas production.
6% of Group revenue
Steam and electricity are widely used as an
energy source in chemical production and
product processing, while our pumps are
used to safely and accurately transfer and
dose critical chemical components.
6% of Group revenue
Electrical heating technologies are widely
used to optimise power generation. Steam
turbines transfer chemical energy in fuel
into electrical energy and steam is used to
distribute and reuse waste heat formed
during the power generation process.
