Annual Report and Accounts 2024

Our approach to reporting
We are committed to transparent sustainability 
reporting and we support efforts to 
standardise requirements.
GRI: this report has been prepared in 
accordance with the Global Reporting Initiative 
(GRI) Standards 2021.
SASB: the report aligns with the Sustainability 
Accounting Standards Board (SASB) chemical 
sector reporting requirements (version 
2023-12). 
TCFD: our Task Force on Climate-related 
Financial Disclosures (TCFD) report is included 
on pages 53-61, and complies with the TCFD 
Guidance for All Sectors. It has taken into 
consideration the Material and Buildings 
Group guidance, as set out in section C of 
‘Annex: Implementing the Recommendations 
of the Task Force on Climate-related Financial 
Disclosures’, October 2021. The numbers 
included in this section cover the entire 
Johnson Matthey group. 
Non-financial limited assurance: ERM 
Certification and Verification Services Limited 
(ERM CVS) were engaged to provide limited 
assurance of selected information as presented 
on page 218. Please see ERM CVS’ Independent 
Limited Assurance Report on pages 216-218 
for more details.
Our products and services are where we believe 
we can have most positive impact on society 
and we have aligned our strategy with four of 
the UN Sustainable Development Goals (SDGs).
The group uses various measures to manage its 
business which are not defined by generally 
accepted accounting principles (GAAP). 
Certain non GAAP measures are included in 
the Annual Report and these are reconciled to 
their GAAP equivalent numbers in note 34 to 
the Financial Statements.
Cautionary statement
The Strategic report and certain other sections 
of this Annual Report contain forward-looking 
statements that are subject to risk factors 
associated with, among other things, 
the economic and business circumstances 
occurring from time to time in the countries 
and sectors in which the company operates. 
It is believed that the expectations reflected  
in these statements are reasonable, but  
they may be affected by a wide range of 
variables which could cause actual results, 
performance, operations, impacts, events or 
circumstances to differ materially from those 
currently anticipated.
We are transforming  
into an industry-leading 
energy transition company

Liam Condon
Chief Executive Officer
Transforming 
Johnson Matthey
When I joined the company two years ago, it was primarily 
known as a tier-two automotive catalyst supplier with a 
history of innovation. But the leadership team and I 
recognised that JM is well-positioned to be so much more 
than that. It is a hub of scientific expertise, ambition and 
experience in delivering solutions that create sustainable 
value and contribute to a cleaner, healthier world.
We announced an ambitious change programme to enable 
us to meet the challenges now faced by our customers. 
We are executing on our transformation at pace across the 
business, creating a more streamlined, efficient and 
commercially focused organisation. We are strengthening 
our capabilities, simplifying our operating model and driving 
improved performance.
You can see more detail on pages 14-15, but you can also 
read on the following pages how our dynamic leadership 
team members are driving these changes. Our Business 
Chief Executives reflect on the transformation in their 
businesses on pages 18-25.
By reshaping our business, we are 
positioning Johnson Matthey for 
long-term growth at the heart of  
the energy transition.

As CFO I’m most proud of the 
progress that we’re making 
to centralise and standardise 
our core processes into JM 
Global Solutions.
 
JM is moving away from a series of 
decentralised, disparate ways of 
working to drive greater efficiency  
and effectiveness in our processes, 
working with our outsource partners 
and our new Vilnius Hub. Our teams  
are doing a tremendous job to enable 
this to happen, including when their 
own positions are uncertain. We are 
already seeing the benefits of this 
transformation in our results.
We have seen a real step-up in 
leadership across our organisation, 
providing direction and clear 
feedback, as well as empowering 
teams to do their best work. 
 
One of my proudest achievements is the  
‘Play to Win’ engagement approach that we 
shaped with our business teams. There is now 
a much better understanding throughout JM 
of our strategy and what is required of each  
of us to implement this. We are delighted  
to see improvements in motivation and 
engagement, especially as we know this is 
rewarding for our employees and leads to  
an overall better customer experience.
In China we have 
successfully 
demonstrated double-
digit growth post 
transformation while 
significantly improving 
employee engagement. 
 
At times we have had to  
make difficult decisions, but as  
a result we are leaner, fitter,  
more agile, more efficient, and 
more productive. We have 
transformed and performed in 
these challenging times in China, 
and customers tell us that it is now 
easier to do business with JM!
We continue to drive a 
cultural change in R&D. 
 
Not only are our teams laser focused  
on driving impact aligned to JM 
strategy, but we have also asked  
people to change the way they  
behave. A much more digital mindset  
is allowing us to implement knowledge 
sharing platforms that accelerate 
innovation. And our customers have 
already noticed; the new apps we use 
internally for product characterisation 
and pricing analyses are now providing 
valuable insight to customers on 
product performance.

I see more and more 
colleagues challenging the 
status quo – seeing 
opportunity instead of 
challenge – through a 
growth mindset lens. 
 
Our teams are seeing transformation 
benefits in terms of cost but also 
easier processes. It’s a reinforcing 
loop: the determination and ambition 
to perform better, in turn pushing us 
to continue to outperform.
I am excited to see how the 
new ‘Play to Win’ culture has 
caught the imagination of 
people across the company. 
 
Teams in every business and function  
are driving significant improvements  
in performance and efficiency. The 
Transformation Office helps shape and 
direct this effort so that we can capture 
the benefits as quickly as possible.  
JM Global Solutions is a powerful new 
capability that will drive Johnson 
Matthey forward. By standardising  
and automating common business 
processes, we can free up our 
commercial, technical and operations 
teams to focus on customers.
Leading through change 
has unlocked a new way 
of working. 
 
Being really sharp on what it is  
each of us does and doesn’t do –  
and where the accountabilities, 
handovers and touchpoints are 
between the businesses and the 
functions – has been a gamechanger. 
It has led to clarity and simplification, 
and empowered all of us with a clear 
understanding of what we each need 
to do to deliver JM’s strategy and be 
successful. The tide has turned!
Sustainability has always 
been a strong motivator  
for our people, and in the 
last two years we have put  
it at the heart of our new 
corporate strategy. 
 
In the same way that we are 
committed to a ‘just transition’ to  
net zero, we are also trying to ensure  
a just transformation of the company. 
The sustainability and communications 
teams are instrumental, supporting  
our employees and using the various 
tools at our disposal to evolve towards 
a ‘Play to Win’ culture and the right 
operating environment.

Chair’s statement
An inflection 
point for PGM 
technology
Exactly 50 years ago, 
the first commercially  
produced catalytic 
converters rolled off the  
production line at Johnson 
Matthey’s facilities  
in Royston, UK and Devon, 
Pennsylvania. 
As it had already been doing for over 
150 years, JM had used its deep knowledge 
of precious metals to create technology  
that would help solve one of the world’s 
problems – this time to tackle appalling  
air pollution. JM had then persuaded 
regulators around the world of the 
technology’s effectiveness. 
Since then, several billion catalytic 
converters have been produced, many 
of them by JM, with countless lives saved 
or significantly enhanced by their removal 
of pollutants.
I believe we are now seeing another 
inflection point for our unique technological 
and metals know-how. Just as we continue 
to innovate the latest generation of clean 
air solutions, so we are harnessing the 
transformative power of platinum group 
metals (PGMs) to enable new solutions, 
from fuel cell electric vehicles to the 
production of sustainable aviation fuel.
PGMs will be key enablers of the clean 
energy transition, and offer several benefits 
over other metals that will also play major 
roles (such as copper, nickel and lithium). 
For example PGMs have a mature, global 
supply chain which won’t require massive 
expansion to meet the needs of the energy 
transition and they offer a sustainable, 
circular solution since they are already 
recycled with very high efficiency.
Our strategy is purpose-driven: to catalyse 
the net zero transition for our customers. 
The energy transition will not be a linear 
journey and is dependent on many factors 
coming together including regulation and 
incentives, infrastructure and supply chains. 
In a complex world striving towards net 
zero, where politics and practicality 
interplay, JM is well placed to succeed by 
understanding the markets, taking 
opportunities, and being flexible enough 
to allocate capital accordingly. Given the 
strength of our portfolio, we are well 
positioned to create significant value 
for both shareholders and society. 
“Just as we continue  
to innovate the latest 
generation of clean  
air solutions, so we  
are harnessing the 
transformative power  
of platinum group 
metals to enable new 
solutions, from fuel  
cell electric vehicles  
to the production  
of sustainable 
aviation fuel.”

In the last six months I have met 
shareholders representing around 40% 
of the ownership of JM, and all can see 
the value of our combination of mature 
business and future opportunities.
We have also streamlined the operations 
of the board, which I believe has made 
us more agile and efficient. We have 
reduced the number of board and 
committee meetings and focused 
our committee membership.

Chair’s statement continued
A resilient portfolio
The divestment of our remaining non-core 
businesses this year has brought welcome 
clarity in our portfolio, in our uses of cash, 
and in the many areas we can continue to 
reduce costs and economise.
We have leading technology to enable 
decarbonisation at scale, whilst also 
benefiting from a strong core current 
business that generates significant cash. 
It is becoming clear that internal 
combustion engines will continue to be 
produced for many years to come. Our 
ever-evolving catalytic converter technology 
continues to be world-leading at removing 
pollutants direct from the engine, and we 
are now even more optimistic about the 
Clean Air business’ cash generation 
opportunities for at least the next decade, 
and likely longer.
We have also had good business wins in 
Catalyst Technologies, with groundbreaking 
achievements. In Hydrogen Technologies 
we are reducing investment and managing 
our cost base to align with the pace of 
market development.
The energy transition is to a large extent 
driven by political vision and policy support, 
and over the coming months we will pay 
close attention to key elections coming 
up in our markets – including the EU, 
UK and the US. 
We have developed strong links with 
key politicians, policy makers, regulators 
and others to explain the benefits of PGMs 
and hydrogen, and continue to secure 
government grants for future developments 
in R&D and the green technology jobs 
of the future.
The divestment of our 
remaining non-core 
businesses has brought 
welcome clarity in our 
portfolio, in our uses 
of cash, and in the many 
areas we can continue 
to reduce costs and 
economise.
Chris Mottershead retired in January 2024: 
I am hugely grateful for his expertise, 
enthusiasm and wisdom over the last nine 
years. Having served for almost four years 
as Senior Independent Director, 
John O’Higgins took over the role of Chair 
of the Remuneration Committee. As ever 
I am grateful to John for his professionalism 
and commitment to the board.
Barbara Jeremiah was appointed as Senior 
Independent Director in July 2023, bringing 
strong experience of metals as well as North 
American markets. 
I would like to thank our employees 
for their hard work and dedication, 
our customers on whom our day-to-day 
energies are focused, and our shareholders 
for their continued support. We are well 
positioned to successfully navigate the 
journey to net zero and create significant 
value for both shareholders and society.

Themes that 
are changing 
our world
Parts of the world continue to be rocked 
by conflict, geopolitical turbulence, inflation 
and cost of living crises. Societies and 
governments are facing many, sometimes 
conflicting, pressures. The energy transition 
needs to be a fair one — but the very evident 
impact of climate change means it is still 
both essential and urgent.
Sustainable energy and fuels
Outlook
Many countries have targets to phase out 
internal combustion engines, increase 
zero-emission vehicles, and tackle emissions 
in other forms of hard-to-abate transport 
such as aviation and shipping. 
Opportunities and challenges
The demand for sustainable fuels is 
expected to grow significantly over the next 
20 years. A wide range of technologies are 
needed to meet this increasing demand, 
including significant investment in clean 
hydrogen technologies, production and 
infrastructure. A number of mandates 
around sustainable aviation fuel are also 
being introduced, such as the US SAF Grand 
challenge equivalent to 10% by 2030, 
and the EU mandate for 6% SAF by 2030.
What we are doing
We have a range of solutions that are 
already providing value to customers 
around the world. Our LCH™ technology 
enables the highest process efficiency 
commercially available today for  
low-carbon hydrogen production, 
and this year was selected by bp and Kellas 
Midstream, amongst others. FT CANS™, 
HyCOgen™ and BioForming® S2A 
technologies are core components of the 
next generation of sustainable fuel facilities. 
Our technologies continue to enable the 
production of methanol and ammonia, 
which amongst other uses will help 
decarbonise shipping emissions. 
Sustainable chemicals
Outlook
Carbon emissions from the chemical  
sector are a common focus for regulation 
because they are easy to find and measure. 
The sector emitted nearly 1Gt of direct CO2 
emissions in 2022. Customers are 
increasingly demanding sustainable 
products to meet consumer expectations. 
Businesses across the industry are looking to 
combine alternative, sustainable feedstocks 
with catalyst technologies to make products 
and processes less carbon-intensive. 
Opportunities and challenges
The key levers to decarbonise the chemicals 
industry include feedstock efficiency, 
alternative feedstocks, use of sustainable 
process energy supply, and application of 
carbon capture and storage. 
What we are doing
We have leading catalysts and process 
technologies that can help the chemical 
industry produce sustainable chemicals, 
with leading positions in syngas and other 
process technologies. Our CLEANPACE™ 
technology solutions can be retrofitted to 
hydrogen and methanol assets to reduce 
carbon emissions by up to 95%. We are also 
one of the participants in the Flue2Chem 
project, spearheaded by Unilever and the 
Society of Chemical Industry (SCI) and 
supported by Innovate UK. Flue2Chem aims 
to take waste gas from foundation 
industries such as metal, glass, paper and 
chemicals, and generate an alternative 
source of carbon for UK consumer products.

Decarbonising modern life
There is wide recognition among governments, businesses and communities of the need 
to tackle climate change by reducing greenhouse gas emissions. To achieve these targets 
we have to make existing industrial processes more efficient, and move to alternative 
feedstocks that are more sustainable.

Themes that are changing our world continued
Creating a  
circular economy
Cleaner air,  
healthier people
An evolving  
regulatory landscape 
Geopolitical and  
economic volatility
Global decarbonisation requires much 
greater efficiency in recycling and reusing 
key materials.
Outlook
There is a growing focus on circularity  
and recycling across industries as 
companies set stronger targets around  
both Scope 3 emissions and waste, and 
respond to stronger regulations around 
recycled content. 
Opportunities and challenges
Embedding circularity into how materials 
are sourced and used is a crucial part of the 
energy transition, particularly with scarce 
resources such as platinum group metals 
(PGMs). Customers are increasingly 
demanding full life cycle offerings from 
purchase to end-of-life recycling. PGMs 
recycling can also be expanded into new 
areas such as emerging technologies in 
electrolytic hydrogen. 
What we are doing
We are already the world’s largest PGM 
recycler by volume, leading in final PGM 
recycling to 99.95% purity. We can offer 
PGMs with low carbon intensity up to 98% 
lower carbon footprint for recycled PGM 
compared to primary (mined) PGM. This 
year our products used 69% recycled metal, 
and we are constantly innovating to design 
our new products with end-of-life recycling 
in mind from the beginning. We are 
applying our longstanding recycling 
expertise to current and emerging 
technologies, including fuel cell and 
electrolyser stacks, as demonstrated 
by our HyRefine™ technology.
As more people live in cities, air pollution 
must be tackled effectively.
Outlook
Air pollution kills millions of people every 
year. With increasing urbanisation and 
a rise in the frequency and intensity 
of heatwaves, which exacerbate pollution, 
significant action is needed to reduce 
harmful emissions.
Opportunities and challenges
The past 12 months have seen lots of 
progress made in the energy transition 
but also many challenges associated with 
it – showing just how complex the task 
of transitioning the world’s energy systems 
is proving to be. While alternative fuel 
sources such as batteries, biofuels and 
hydrogen grow, it is becoming clearer 
that automotive catalysts for internal 
combustion engines will likely be needed 
for years to come, including for emerging 
economies that cannot yet afford high-cost 
low-carbon solutions. 
What we are doing 
Today, one in three cars carries JM’s 
emission control technology. And we 
continue to invest and innovate to ensure 
that our technologies help customers meet 
new legislation. We have a strong global 
manufacturing presence and world-class 
labs and test centres that continue to 
enhance autocatalyst performance while 
innovating the use of our core technologies 
for emissions controls in future applications. 
Governments continue to recognise 
their role in promoting investments 
into sustainable technology.
Outlook
We are seeing a growing body of national 
legislation and other incentives aimed at 
tackling climate change, resource scarcity 
and energy insecurity. The Inflation 
Reduction Act in the USA, the EU Green 
Deal Industrial Plan and the UK’s formal 
commitment to reaching net zero by 2050 
all look to incentivise the increased use of 
sustainable technology. 
Opportunities and challenges
Despite short-term uncertainty around 
the exact structure of some incoming 
regulations, the market is moving strongly 
in our direction. Across the energy, 
chemicals and transport sectors, the 
transition will likely involve a mosaic of 
different technologies and processes – 
many of which we provide solutions for. 
What we are doing 
We work with our partners and peers to 
create the industry voice to help shape 
policy in a way that supports an ambitious 
and just energy transition. We engage with 
stakeholders across the regulatory 
landscape and highlight how our products, 
technologies and services can be best 
deployed to help the world through the 
energy system transformation.
Businesses and communities are 
navigating an external landscape 
defined by uncertainty.
Outlook
2023/24 saw an increase in geopolitical 
volatility caused by the war in Ukraine, 
ongoing tension between the US, EU 
and China over issues of economic and 
national security, the conflict in Israel/Gaza, 
and a rise in the popularity of nationalistic 
politics. Weak economies, global inflation, 
tight monetary policy and restrictive 
financial conditions have all impacted 
growth. Although inflation is expected 
to decline in the major Western economies, 
the global economic outlook will remain 
uncertain for some time. 
Opportunities and challenges
As governments in all our markets seek 
to drive economic growth, whether by 
stimulating domestic spending or funding 
the energy transition, new opportunities 
are created for our products and process 
technologies. Our challenge is to identify 
the markets and customers which represent 
the greatest opportunities for growth. 
What we are doing 
As well as strengthening our commercial 
muscle, our ongoing transformation 
is increasing JM’s resilience and positioning 
us to take full advantage of the 
opportunities created by the energy 
transition. We are reducing our costs, 
optimising our capital investments and 
focusing on the markets with the greatest 
potential for growth.

Expertise in metal chemistry
Everything we do across our four businesses is 
underpinned by our leadership in complex metal 
chemistry, catalysis and process engineering.
Foundational PGM ecosystem
We have deep insights into PGM markets through our 
Precious Metal Management team and our refining 
operations. Around 80% of the PGMs we use are 
sourced internally from our refineries. This shared 
resource creates a resilient supply, lower exposure 
to price risk and efficient working capital. 
Mutual customers and partners
As our customers transition to net zero, we provide  
a fully integrated and comprehensive offering  
through collaboration across our business units.
Security of supply
Our customers count on us for a reliable supply of 
PGMs and recycling services – we supply over 40%  
of the PGMs sent to our Clean Air customers. This is 
because we are a metal hub for PGMs, underpinned  
by our status as the leading recycler of PGMs.
Shared technology and capabilities
We have more than 2,400 colleagues in R&D  
and engineers across all our businesses – 
with around 4,000 patents granted and around 
2,000 applications pending.
A comprehensive sustainability offering
Every part of our business is committed to helping  
our customers adapt processes and products to reach 
the sustainability goals our society and planet are 
depending on.

the production of chemicals, 
helping customers lower  
their carbon and 
environmental footprint.
Automotive
Emission control systems  
that reduce NOx and other 
particulates that harm people 
and the environment.
JM helps store and transport renewable energy 
by enabling the production of renewable 
(green) hydrogen. Our solutions also help 
produce low-carbon methanol and ammonia, 
which can transport hydrogen efficiently and 
will play a role in decarbonising the shipping 
industry. We also provide processes and 
catalysts to produce sustainable aviation fuels, 
helping the industry reach its net zero target. 
We develop catalysts that increase the 
efficiency of chemical reactions, thus lowering 
energy requirements and carbon emissions. 
We also provide solutions to accelerate the 
chemical industry’s transition to a more 
sustainable future: by lowering the emissions 
of existing industrial assets, and by providing 
solutions for the manufacture of sustainable 
chemicals and fuels, and the clean hydrogen 
feedstock for these products.
As the transition to decarbonised 
transportation will be gradual, we ensure 
non-CO2 emissions from internal combustion 
engines, including zero carbon hydrogen 
engines, are minimised through our leading 
autocatalyst solutions. We also have solutions 
that enable zero emission mobility through 
our fuel cells technology.

Chief Executive Officer’s statement
A year of 
progress at pace
At JM our strategy is  
clear: we are a sustainable 
technology company that 
plays to win with leading 
positions in key markets 
that depend on innovation. 
Our innovation allows  
our customers in the 
automotive, chemical  
and energy industries 
to decarbonise at pace 
and helps ensure cleaner 
air for all.
To achieve our purpose of catalysing the 
net zero transition at scale, JM itself needs 
to transform, become even more efficient 
and build a stronger foundation for growth. 
This year we have made significant progress 
towards achieving this. 
Winning in our markets
Our performance for the year has been  
in line with expectations, with good  
growth in underlying operating profit 
when allowing for exchange rates and 
metal prices. Overall results continue 
to be impacted by lower platinum group 
metal (PGM) prices.
The slowdown in global battery electric 
vehicle (BEV) penetration means Clean Air 
will be ‘stronger for longer’ – driving more 
than £4.5 billion of cash by 2030/31 and 
significant further cash flow beyond that. 
Our cash generative ability has already 
delivered £2 billion in Clean Air since 
2021/22, which has been used for 
investment in growth and 
shareholder returns.
In Catalyst Technologies, we are seeing 
significant end market demand across our new 
growth areas including sustainable aviation 
fuel and low carbon hydrogen. This year we 
have seen important ‘first of a kind’ project 
wins, including two large-scale low carbon 
(blue) hydrogen projects. We also have a 
portfolio of innovative technologies for creating 
sustainable fuels, and during 2023/24 we 
secured four sustainable fuels projects across 
our Fischer Tropsch (FT) CANS™ technology 
and sustainable methanol. 
In Hydrogen Technologies, it is very clear 
that green hydrogen will be essential in 
tackling climate change and helping the 
world to decarbonise. The global green 
hydrogen value chain is still at an early 
stage of development as the industry 
navigates the challenge around scale up, 
and is not yet growing at the pace we 
expected. We have a disciplined approach 
to investment and plan to grow our 
Hydrogen Technologies business in line 
with the pace of market development. 
“We are becoming much 
more commercially-
minded, and continue  
to drive significant 
efficiencies as we 
‘right-size’ the 
organisation.”

Chief Executive Officer’s statement continued
Platinum Group Metal (PGM) Services 
is our foundational business and forms the 
backbone of everything we do. Circularity 
is an essential part of the energy transition 
and our PGM expertise strengthens our 
position in key markets through our ability 
to offer a full-service business model. 
We can deliver circular solutions for 
customers ensuring a reliable supply 
of lower carbon footprint PGMs.
Transforming for growth
The table on the right demonstrates 
the progress we have made against our 
strategic milestones. Across the group, 
the transformation is well underway 
to build a stronger and more efficient 
platform for growth.
We have simplified our portfolio into four 
core businesses and by the end of 2023/24 
we agreed the divestment of all the other 
non-core businesses. The Battery Systems 
sale completed in April 2024, and Medical 
Device Components is due to complete later 
in the year. These divestments will deliver 
net proceeds of more than £500 million, 
significantly exceeding our target of more 
than £300 million.
We are becoming a much more 
commercially-minded organisation, 
with a highly disciplined approach 
to capital projects. We continue to drive 
significant efficiencies as we ‘right-size’ 
the organisation including management 
streamlining and efficiencies in both 
our enabling functions and businesses. 
These have delivered total cost savings 
to date of approximately £120 million, with 
targeted savings of £200 million by the end 
of 2024/25. We are making good progress 
in implementing our new outsourced 
business process organisation JM Global 
Solutions (JMGS) to simplify and increase 
efficiency, with new service hubs in 
Lithuania and India.
We have now developed new ambitious 
strategic milestones, outlined on page 15, 
focused on customers, capability 
and transformation.
We have seen several changes to our Group 
Leadership Team (GLT). Jane Toogood 
and Christian Gunther left JM in the autumn 
of 2023, and Nick Cooper at the end 
of March 2024. I am very grateful to Jane, 
Christian and Nick for their hard work 
and support to JM.
Maurits van Tol, our former CTO, 
has succeeded Jane as Chief Executive 
of Catalyst Technologies last autumn. 
Liz Rowsell has become our new CTO and 
Louise Melikian has become our new Chief 
Strategy and Corporate Development Officer. 
In addition Simon Price was appointed as 
General Counsel and Company Secretary 
and Peter Hill has taken over as Group 
Global Services and Transformation Director. 
The fact that all of the appointments were 
internal placements speaks for the 
significant step-up in the quality and 
diversity of succession planning at JM.
The company continues to experience 
a lot of external change and internal 
transformation, and the GLT and I are 
acutely aware of the importance of 
employee engagement in order for us to be 
successful in volatile times. It is testament 
both to our people’s resilience and their 
capabilities that both our safety record 
and employee engagement scores 
have improved considerably this year. 
I am extremely grateful to all our employees 
for their hard work, commitment and 
unwavering dedication to implement 
our strategy and to look after our customers 
and each other at all times.

Our strategy
We are playing to win in exciting growth markets where our core competencies and technology portfolio can have maximum impact
Our expertise in PGM chemistry, catalysis and process technology is the beating heart 
of JM, and we are maximising synergies across our four business units to achieve a top 
three position in all our markets.
Our transformation programme is enhancing simplification and execution across the 
entire business. We are becoming a simpler, more agile and more cost-effective 
organisation with leaner processes, less duplication and clear lines of accountability.
Across the year, we realised approximately £75 million of new savings, resulting in 
£120 million in transformation savings relative to the actual financial year 2021/22 cost base. 
Some notable achievements include: 
•	 Launch of Johnson Matthey Global Solutions (JMGS), delivering a new way of supporting 
core business services to support HR, Finance and Procurement teams through our new 
JM service hub in Lithuania and a dedicated centre in India. JMGS rolled out to the US 
in February 2024.
•	 Roll-out of the Johnson Matthey Production System (JMPS), delivering structured 
improvement in our manufacturing operations.
•	 Closure of four Clean Air manufacturing facilities as we continue to consolidate in fewer, 
more efficient and flexible sites. 
•	 Resizing of our managerial structure to reflect the new size of the company, partly driven 
by divestments and closure of underused assets.
•	 Accelerated progress of our procurement transformation, with a new operating model 
and closer supplier relationships signified by our first global JM supplier convention; 
and margin improvement savings of £34.4 million in 2023/24.
•	 Strengthening of our Engineering and Capital Project (ECP) delivery, including a new ECP 
operating model that has streamlined the number of suppliers, allowing a clearer focus 
on value. 
Our priority actions for the year ahead include:
•	 Continued roll-out of the JMGS programme, launching in the UK in May 2024.
•	 Redesign of the IT Operating Model to support the future growth of JM.
•	 Fully deploy the new global Procurement organisation, co-ordinated with the JMGS 
implementation, and supported by a new procurement digital platform.
•	 Right-sizing and upgrading of JM’s real estate footprint for future business needs, 
including the expected sale of unused land in the US and the consolidation of existing 
London offices into our new London Hub.
•	 Consolidate to a single global payroll provider.
•	 Deploy a common ERP landscape for PGM Services, replacing 13 legacy systems.
We agreed the divestment of all our Value Businesses this year, in line with the strategic 
milestone set in 2022. We completed the sale of our Diagnostic Services business 
in September 2023, and confirmed the sale of our Medical Device Components 
and Battery Systems businesses in March 2024.
Over the three year period to 2026/27, we expect cumulative capital expenditure of up to 
£900 million. This will be focused on supporting the core competencies essential for driving 
our long-term growth and value creation. We are maintaining a strong balance sheet and 
investing for growth and attractive returns, ensuring a reliable dividend and returning excess 
cash to shareholders.

Our strategy continued
Following the successful delivery of our previous strategic milestones (page 13), we  
have refreshed our targets for the next two years. Focusing on customers, capability and 
transformation, our new milestones build on the results we have achieved over the last two 
years to make sure JM remains well placed to deliver on our short and longer-term priorities. 
Group Commercial Council
We continue to strengthen our commercial muscle through our Commercial Council. 
This year we further embedded the voice of customer in our business, improving our 
overall customer satisfaction (Net Promoter Score (NPS)) to 43, compared to 37 in 
2022/23. All four businesses improved their NPS scores, with customers highlighting 
the strengths in our technical expertise, product performance, collaboration and 
supportive service. Our commercial teams are being upskilled, with the successful 
roll-out of sales incentive plans and skills training delivering strong wins across 
the businesses. We are further harnessing the power of a oneJM approach to our 
customers, maximising our current partnerships through targeted cross-selling 
and building new profitable business. Looking forward, we will increase our level 
of ambition around new business wins through our oneJM approach and enhanced 
customer-centricity across the company.
Our strategy is underpinned by a rigorous performance culture. By combining science 
and purpose with a more commercial mindset, we are driving stronger execution, 
unlocking near-term cost opportunities and positioning ourselves for long-term growth.

This year marks the 50th anniversary of our 
emissions control technologies, which have 
saved many thousands of lives so far and will 
continue to protect the health of many 
millions more into the future. 2023/24 saw 
us continue to execute on our strategy and 
play to win by delivering on our financial 
targets, reducing our costs and supporting 
a high-performance culture. As we continue 
to strengthen our business for the long term, 
we are also actively leveraging our 
technology to win growth opportunities 
around and beyond automotive catalysts.
In parallel, we have adapted to our dynamic 
market through continuously strengthening 
our commercially-focused approach.
We are seeing a slight cooling of the battery 
electrification market, which has led in turn 
to an increase in near-term volume forecasts 
for our products in some key markets. 
This change, coupled with the agreed later 
introduction date of Euro 7 legislation, 
has begun to influence future bids and 
contract acquisitions.
Due to bid outcomes from previous years, 
we are prepared for a reduction in volumes 
in 2024/25. This will be fully mitigated by our 
costs transformation and the cooling of the 
electrification market. Against this backdrop 
we continue to win with customers, with 
several large-scale business wins expanding 
our presence in key markets. 
Clean Air
Leading emission reduction technology,

Transforming at pace 
During 2023/24, we implemented positive change across all levels of the business. 
This is delivering more value for customers today and positioning the company 
to capitalise on new future growth areas. 
“We are fully focused 
on delivering our cash 
generation target, 
further strengthening 
our commercial 
capabilities, winning our 
targeted business and 
driving efficiencies.”

Clean Air 
Pricing 
We are offsetting commercial headwinds by optimising pricing 
and reducing value leakage through the contract life cycle.
Manufacturing footprint 
We completed the targeted closure of four facilities as part of our ongoing 
work to consolidate our manufacturing base in fewer, more efficient and 
flexible sites, with plans for further consolidation under consideration. 
We worked with employees, customers, suppliers and communities 
to ensure a smooth and safe transition.
Efficiencies
We are driving cost efficiencies throughout the business, from 
procurement to production. In product management we are designing 
to value, optimising our manufacturing processes to reduce input 
requirements while improving performance. The transformation of our 
procurement function is allowing us to implement significant savings 
in both direct and indirect purchases. And we continue to improve our 
manufacturing excellence, with the standardised JM Production System 
(JMPS) that was piloted by Clean Air in 2020 now being rolled out across 
the group.
High-performance culture 
Through clear strategy, embedded leadership behaviours and a culture 
of open and honest two-way feedback, our employees can excel and 
innovate continuously to achieve our shared goals.

score (NPS) increasing by seven points to  
24. Customers praised our collaborative 
approach and technical excellence, while also 
highlighting the need to be more consistently 
responsive across our customer base.
We maintained a good safety record, 
achieving top-quartile status for safety 
performance when benchmarked against 
peers in the chemical sector.
The successful closure of four factories 
shows our commitment to operational 
excellence and ensuring a zero-harm 
environment for our employees, customers 
and the wider community without 
disrupting our customers’ operations.
Seizing the growth opportunities 
of the energy transition 
Our leading technology and expert teams 
have a significant role to play in the move 
to a low-carbon economy. Our strategy is 
about more than delivering today — we are 
also strengthening Clean Air for decades of 
future growth around and beyond 
automotive catalysts. We are applying our 
expertise in new and developing growth 
areas, such as emission controls for 
hydrogen-fuelled combustion engines, and 
solid oxide fuel cells.
Looking forward 
We are focusing on delivering our cash 
generation target, further strengthening 
our commercial capabilities, winning our 
targeted business and driving efficiencies. 
Our development of world-leading catalysts 
will continue to be supported by tightening 
global emissions controls. In Europe, 
a provisional agreement has been reached 
on Euro 7 emissions standards. We estimate 
the new standards will come into effect 
from 2027 for light duty and 2028 for 
heavy duty vehicles. Beyond Europe, we 
expect more developments globally, with 
the US already setting tighter standards 
from 2027 onwards and China and India 
expected to bring proposals in 2024/25.
With the continual improvement of our core 
business, the external signals of a slowdown 
in the battery electric vehicle (BEV) market, 
and the growth opportunities around and 
beyond automotive catalysts, we believe 
the Clean Air business continues to have 
a bright future.
Our performance in 2023/24 
Clean Air is well on track to reach its 
original target of generating at least 
£4 billion of cash by 2030/31, with 
£2 billion already delivered in the three 
years to date. As a result we have upgraded 
our target to at least £4.5 billion of cash 
by 2030/31. 
As well as continuing to deliver key business 
wins, our performance this year was 
underpinned by the ongoing execution of 
our strategy to improve cost efficiencies, 
consolidate our footprint, and strengthen 
our commercial capabilities. 
We are delivering against our strategic 
milestones by winning profitable business 
across a range of industries and markets. 
Throughout the year, we won targeted 
Euro 7 business and added several 
large-scale business wins to those won 
in 2022/23, growing our future share 
of market. Our localised approach in China 
is helping us tap into growing market 
appetite across the region. Strategically 
focused R&D activities helped strengthen 
our performance by creating efficiencies 
and improving customer experience.

Platinum Group  
Metal Services 
Our deep knowledge and experience in 
platinum group metals (PGMs)and their 
chemistry is critical in the transition to net 
zero. We harness the unique properties of 
these metals to tackle complex technology 
challenges for our customers across the wide 
range of markets that we serve. In addition 
to existing uses, the energy transition is 
driving future demand for PGMs in many 
new applications.
PGMs from the majority of these applications 
can be recycled and reused in new products 
indefinitely. As a world-leading recycler 
of PGMs, at twice the size of our nearest 
competitor (by volume), we currently refine 
circa 20% of all PGMs globally from primary 
and secondary sources. This circular business 
model puts JM right at the heart of the shift 
to a more sustainable world.
We are transforming our PGM Services 
business so that we can create more 
long-term value for customers in existing 
and new markets. 2023/24 saw us develop 
our product pipeline and pioneer a new 
circularity solution for the hydrogen 
economy, while investing in our assets  
and delivering increased operational 
efficiencies. We’re already seeing the 
benefits of these improvements in our 
customer satisfaction, with our net promoter 
score (NPS) increasing from 35-43.

Platinum Group Metal Services continued
profit was down by 35% to £164 million. 
Additionally, levels of autocatalyst scrap 
remained low.
In response to these headwinds we focused 
on developing our products business, which 
is largely independent of metal prices, while 
also driving cost savings and operational 
efficiencies. The PGM Services product business 
has doubled since 2019 as we grow our 
product base beyond auto catalysts and 
develop new PGM applications – including 
in the hydrogen economy, pharmaceutical 
and agrochemical markets. After allowing 
for metal prices and exchange rates, PGM 
Services underlying operating profit was 
broadly flat in the year.
Other R&D initiatives in 2023/24 concentrated 
on safely extracting PGMs from complex 
new feeds and reducing the environmental 
footprint of our refining process.
To drive operational efficiencies we are 
automating and optimising processes 
within our plants. We opened new refining 
capabilities in China, and we can now provide 
a full refining offer to our customers across 
the region. We continue to progress our new 
refinery investment in the UK which 
is now in the final execution stage and 
is on schedule to be completed in 2026.
Looking ahead 
We have an important role to play in the 
global shift to more sustainable energy 
systems, by leveraging our expert knowledge 
of PGMs and the increasing demand they are 
facing across industries including aviation and 
life sciences as well as the hydrogen economy. 
We will continue to evolve our product 
portfolio by developing innovative and 
circular offerings, creating fully circular 
models that enable our customers to meet 
increasingly stringent environmental targets. 
Improving our own operational efficiency 
remains a cornerstone of our strategy: we are 
investing in our refining assets and upgrading 
them where necessary to ensure they give us 
sustainable competitive advantage.
Pioneering circularity for the hydrogen 
economy with HyRefine™ technology
2023 saw PGM Services break new 
ground in the hydrogen economy with 
the successful lab-scale demonstration 
of our HyRefine technology. As the 
number of hydrogen projects 
worldwide continues to grow, there 
is a need to embed circularity into the 
process from the start. With HyRefine 
we now have a way of recycling the two 
most critical components of hydrogen 
fuel cells and electrolysers: the PGMs 
in the catalyst layer, and the 
membrane ionomer. These can be 
recycled into new catalyst-coated 
membranes, a core component of 
hydrogen fuel cells and electrolysers.
HyRefine uses a purely chemical 
process and provides significant cost, 
efficiency and sustainability benefits. 
When compared to traditional PGM 
refining its carbon footprint is up to 
80% lower, with:
•	 83% less waste produced
•	 79% less energy used
•	 67% less water used
Following successful five-litre 
lab-scale demonstrations in November 
we are now scaling up HyRefine 
for 50-litre pilot trials at our facility 
in Brimsdown, UK.
Our performance in 2023/24 
During 2023/24 the market environment was 
challenging as rhodium and palladium prices 
continued to decline. These developments 
adversely impacted the entire PGM 
ecosystem, as demonstrated by restructuring 
announcements from several major mining 
businesses. As a result, sales declined by 17% 
to £462 million and underlying operating

Leading in circularity 
This year we made significant progress 
on delivering innovative circular 
solutions for customers across a wide 
range of sectors. One key development 
was our HyRefineTM technology, which 
recycles both the membrane and the 
PGMs in the performance-defining 
components of hydrogen fuel cells 
and electrolysers. This enables both 
of these valuable materials to be 
reused, while reducing waste and 
emissions in the refining process. 
We continue to demonstrate how 
PGMs can play a central role in 
promoting circularity and addressing 
availability gaps within the global 
energy ecosystem.

Catalyst  
Technologies
Catalyst Technologies is a core growth driver 
for JM. Through our expertise in process 
technology and catalysis, we enable the 
efficient creation of chemicals and fuels 
that benefit millions of people every day.  
As the world is also looking to convert 
alternative feedstocks for energy and fuels, 
we are operating in markets with enormous 
growth potential. Our technologies are 
largely feedstock-agnostic, so we can  
serve organisations that need a trusted, 
experienced technology partner, whether 
for the efficient conversion of fossil 
feedstock or new alternative feedstocks 
such as biomass, municipal solid waste  
and captured carbon dioxide.
Winning business in 
sustainable solutions 
Low-carbon (blue) hydrogen 
JM offers both autothermal reforming 
(ATR) and gas heated reforming (GHR) 
technologies for the low-carbon (blue) 
hydrogen and ammonia market. We have a 
very long history in the deployment of ATR 
with reference plants around the world.
The combination of our ATR technology 
with a gas heated reformer brings further 
advantages: it enables higher process 
efficiency and lower feedstock usage 
compared to conventional ATR technology, 
and we are delivering projects that will 
capture over 98% of CO2 produced.
In 2023/24, we won two large-scale low 
carbon (blue) hydrogen projects in the UK 
– H2 NorthEast with Kellas Midstream and 
bp’s H2Teesside. We have a strong pipeline 
for further ATR-only and ATR-GHR projects.
Sustainable fuels 
JM has a portfolio of innovative  
technologies for creating sustainable fuels. 
Our award-winning Fischer Tropsch (FT) 
CANSTM technology developed with bp 
converts syngas into sustainable fuels, 
and when paired with our HyCOgenTM 
technology, can convert captured CO2 
and electrolytic (green) hydrogen made 
from renewable energy into e-fuels. 
We also provide sustainable methanol 
technologies including our proprietary 
eMERALDTM CO2 to methanol process, 
building on our leading position and deep 
expertise in conventional methanol 
licensing. In addition we license the 
BioForming® process originally invented by 
Virent and co-developed by JM and Virent, 
which helped to power Virgin Atlantic’s 
demonstration of the first transatlantic 
100% sustainable aviation fuel flight by 
a commercial airliner in November 2023. 
In 2023/24, we secured four sustainable 
fuels projects across FT and sustainable 
methanol. In March 2024 we won the 
largest sustainable aviation fuel project in 
the world using the FT route, with DG Fuels.

Deploying our leading LCHTM  
technology in H2Teesside
This year we signed a licensing and engineering agreement for our LCH technology 
at bp’s proposed flagship low-carbon (blue) hydrogen facility in Teesside. This aims 
to be one of the UK’s largest low-carbon hydrogen facilities, targeting 1.2GW 
of hydrogen production by 2030 – which would represent over 10% of the UK 
Government’s hydrogen target of 10GW by 2030.
Industry in the Tees Valley accounts for 64% of total local CO₂ emissions, compared 
to 24% nationally. H2Teesside will help power and decarbonise existing local industry, 
as well as new businesses attracted to this low-carbon hydrogen produced at scale.
licensing. As we win more business in the 
blue hydrogen, sustainable fuels and 
chemicals markets, we expect 40% of our 
business to come from licensing by 2030. 
We implemented a value creation 
programme focused on value-based pricing, 
manufacturing excellence and procurement 
efficiencies. This is putting us on track to 
meet our longer-term margin targets and 
creating more value for our customers. 
To capture the opportunities we see 
in the market we expanded our commercial 
capability in the US and are opening a new 
office in the Middle East. We increased 
the number of engineers in our teams 
by 20% over 12 months to support our 
Licensing business.
Looking ahead
Our first priority is always the safety of our 
people. CT has made great progress this 
year on our commitment to not harming 
anyone as a result of our processes and 
activities, lowering our process incident 
severity rate by 76% and total recordable 
injury and illness incident rate by 27%. 
Our second priority is to deliver on  
our near-term financial commitments 
through continued efficiency and 
productivity measures. 
Our third priority is to grow for the future 
by winning more projects in sustainable 
technologies on top of a very solid base 
in our existing licensing business.

Our performance in 2023/24
We performed strongly across 2023/24. 
We executed on our strategic milestone 
to secure 10 additional large-scale project 
wins across 2022/23 and 2023/24, 
demonstrating our commercial and 
technical strength in blue hydrogen and 
sustainable fuels. Sales were up 6% with 
strong growth in Licensing, up 20%. 
In Catalysts, we saw higher average prices 
across our portfolio and delivered strong 
performances in formaldehyde and key 
syngas segments. In Licensing, we made 
progress in scaling our business and 
targeting new opportunities. Big wins in 
low-carbon hydrogen and sustainable fuels 
alongside other areas like oxo alcohols and 
butanediol demonstrate the strength of our 
offering. We are a trusted partner to our 
customers all the way from initial project 
design through to commissioning and 
ongoing technical support. The value we 
provide is reflected in our industry-leading 
customer satisfaction NPS score of 54 this 
year. As a result, our underlying operating 
profit was up 56% to £75 million, and our 
underlying operating profit margin grew 
390 basis points to 13.0%.
Transforming for future growth
This year we significantly simplified the 
business by evolving the previous CT 
structure into two business units, Catalysts 
and Licensing, to drive faster decision- 
making. Currently most of our business

“Collaboration along the 
whole of the hydrogen 
value chain is essential 
for the energy transition 
to be successful. Recent 
market developments 
accentuate the need for 
partnerships." 
Mark Wilson, Chief Executive, 
Hydrogen Technologies
The long-term importance of hydrogen  
is becoming increasingly clear. It is  
essential for tackling the generational 
challenges of climate change and global 
decarbonisation — particularly in sectors 
where driving down emissions poses a 
significant challenge. We believe we 
are uniquely positioned to be a leader 
in this vital market. 
In Hydrogen Technologies we provide 
critical components for the growing 
hydrogen economy, underpinned 
by decades of experience in fuel cells 
and a deep understanding of PGMs.
Whilst we still believe in the long-term 
future of hydrogen, there has been a 
slowdown in growth throughout the year. 
Continued uncertainty about the exact 
nature of the financial incentives for 
hydrogen investment in the US and  
Europe has resulted in delayed investment 
decisions and slowed progress on existing 
projects. We are adapting to the changing 
demand profiles of our customers as they 
navigate this short-term uncertainty. 
Throughout 2023/24 our priorities were 
diversifying our customer base and strategic 
partnerships, scaling the business and 
delivering sales growth.
Delivering efficiencies  
in manufacturing 
Over the past year, we have focused on 
improving our operational performance  
and have made good progress rolling  
out manufacturing efficiency initiatives. 
In particular we have increased the line speeds 
and improved the overall effectiveness of 
our equipment, driving greater output from 
our plant in Swindon, the UK. The success of 
these initiatives has allowed us to optimise 
our planned investment.
Transforming for our customers 
We are working to maximise synergies across 
the JM group and deliver an enhanced and 
collaborative value proposition to our 
customers. The successful demonstration  
of JM’s HyRefineTM technology this year 
generated lots of interest and represents a 
significant enhancement of JM’s end-to-end 
suite of hydrogen offerings. 
In a new and evolving market, organisations 
need strategic partners with experience, 
capability and market-leading technology. 
Building on a unique position, we expanded 
a long standing partnership with a leading 
provider of fuel cells. While the relationship 
has previously centred on direct methanol 
fuel cell systems, it will now transition 
to the development of proton exchange 
membrane (PEM) components for 
hydrogen fuel cells, an ultra-low carbon 
intensity alternative to those powered  
by fossil fuels. Higher customer satisfaction 
scores in 2023/24, demonstrated by an 
increase in Net Promoter Score, show  
that our approach is working and that 
customers across the portfolio see the  
value that JM provides.
Our performance in 2023/24
Sales for the year were up 31% to 
£71 million, driven by demand from our 
strategic customers. Our underlying 
operating loss of £50 million reflects our 
considered investment in building capacity 
and product development in line with 
market growth. Despite the challenging 
external environment, we progressed deals 
with new customers, expanded existing 
strategic partnerships, and continued to 
work with new customers on both our 
specialised catalyst-coated membranes 
(CCMs) and membrane electrode 
assemblies (MEAs).

Introducing major technical 
advancements in fuel cells 
Our ongoing R&D activities are improving our process technologies 
and driving improvements in the next generation of products. 
A key way we do that is through optimisation of PGM content 
in our products to drive real value for commercial applications. 
Iridium can be deployed in fuel cell anodes as an effective key 
ingredient to improve durability and has properties that can handle 
fluctuations in the hydrogen supply. In 2023, we developed a new 
low iridium anode for fuel cells that required 90% less iridium than 
previous technologies. Not only does it translate to less iridium 
required for the product, but it also delivers three times the 
improvement in mitigating hydrogen supply instability. We continue 
to work closely with our customers to drive product efficiencies 
as we strive for even more significant improvements in PGM loading 
and durability in the next generation of products.
Looking ahead
We have positioned ourselves well in our 
core markets in North America, Europe  
and China. In the US, our planned 
investment remains on hold whilst we 
evaluate future market evolution and  
supply plans with our customers. In the  
UK, whilst construction of our new plant  
in Royston is substantially complete, 
we are re-aligning the start of production  
with market development. In China, 
we are continuing to progress customer 
relationships, especially in fuel cells, and 
continue developing partnerships whilst 
remaining disciplined in our approach  
to scale up in this fast-growing market.
We are playing to win in the hydrogen 
market. Despite a market slowdown, 
hydrogen is still an essential part of the  
net zero transition. It is critical that we 
continue to develop our leading-edge 
technology to better meet our customers’ 
evolving needs. In the immediate term we 
are reducing our investment and operating 
costs to manage the business in an agile 
way, ensuring we are ready to scale in line 
with market growth.
Heading into 2024/25 we are focusing on 
taking the steps needed to establish a 
leadership position in our market, whilst 
ensuring that our business is more agile, 
efficient, and capable of leveraging the full 
expertise of JM. As the short-term market 
demand continues to change and develop, 
we are diversifying our customer base and 
continuing to drive increased efficiencies 
in manufacturing – and we are expecting to 
break-even by the end of 2025/26. These 
strategies underscore our commitment to 
creating a hydrogen-powered future.

We have performed well this 
year, delivering 11% growth  
in underlying operating 
performance, when adjusted  
for metal prices and exchange 
rates. However, significantly 
lower platinum group metals 
(PGM) prices have again 
impacted our overall results, 
with revenue down 14% to  
£12.8 billion. Sales were down 
4% at £3.9 billion at constant 
exchange rates. During the year 
we managed to partly mitigate 
this through better pricing 
and transformation benefits 
across the group.
As we execute on our strategy we are 
focused on driving sustainable value 
creation, targeting high single digit growth 
in underlying operating profit over the 
medium-term and strong long term growth. 
Transformation on track
Our transformation is well underway 
to drive efficiency and build a stronger 
platform for growth. During 2023/24 
we delivered cost savings of £75 million, 
bringing total cost savings to date to 
£120 million. As a result we have increased 
our targeted savings to £200 million by the 
end of 2024/25, up from our previous 
target of in excess of £150 million.
Chief Financial 
Officer’s statement
As we drive efficiencies across the group, 
this year we closed four out of 16 Clean Air 
manufacturing sites as we continue to 
rationalise our footprint into fewer, larger, 
more efficient locations. By the end of 
2025/26 we plan to have closed at least 
20 out of 27 of our leased office buildings.
Last year we announced we would be 
moving to a new global business services 
model to simplify how we provide internal 
services. We have made good progress with 
JM Global Solutions up and running 
delivering from our new service hubs in 
Lithuania and India. We are now 
transferring significant parts of our Finance, 
HR and Procurement services to this new 
model, which we are confident will provide 
a better experience for our colleagues as 
well as delivering significant efficiencies.
Inevitably, the pace and ambition of our 
transformation has incurred some one-off 
costs. This year we incurred £78 million 
of one-time restructuring charges linked 
to the transformation programme and 
site rationalisation. 
During 2023/24 we agreed the divestments 
of our remaining non-core businesses, with 
the sale of Battery Systems completing  
in April 2024, and Medical Device 
Components expected to be finally divested 
by the autumn of 2024. We now have 
a more focused portfolio, and this has 
enabled us to drive further efficiencies  
and reduce costs.

Although the disposal of Battery Systems 
resulted in a £45 million non-cash 
impairment (recognised at 31st March 2024 
to reduce the business to its disposal value), 
the divestment programme as a whole will 
have delivered net proceeds in excess of 
£500 million, significantly exceeding our 
target of more than £300 million. Once the 
divestment proceeds have been received, 
we intend to return £250 million to 
shareholders via a share buyback. The 
remainder will be used to pay down debt, 
and for other general corporate uses.
Individual business 
performance
Clean Air has been focused on winning  
new business, driving efficiency and 
delivering cash. The business has been 
working on improving margins through 
pricing, cost reduction and operating 
excellence, as well as the ongoing site 
rationalisation programme, setting a 
roadmap to achieve an operating margin 
target of mid-teens by 2025/26. The 
slowdown in battery electric vehicle 
penetration means we now expect Clean  
Air will be ‘stronger for longer’, and we  
now expect the business to deliver over 
£4.5 billion cash in the decade to 2030/31 
(previously at least £4 billion) and significant 
further cash flow in the years following.
PGM Services is a key enabler for the group, 
but its results have been materially 
impacted by lower precious metal prices. 
In the short-term, we have mitigated some 
of the impact through continued focus 
on efficiencies across areas including 
operations and manufacturing. Over the 
long-term, the business is expected to see 
sustained demand for recycled PGMs due 
to growing demand for low carbon metals. 
The business is also looking at evolving its 
business model to reduce the impact of 
metal price on earnings and growing 
value-added products businesses.
Catalyst Technologies has undergone a 
change in management and reorganisation 
to drive improved performance and ensure 
it fulfils its growth potential. In the year, 
the business has seen continued 
improvement in short-term performance 
and is winning new projects in sustainable 
technologies. The business continues to 
focus on improving margins and saw further 
improvement in the second half. We have 
also been winning exciting new business 
across our sustainable solutions portfolio, 
with a rich pipeline of further opportunities. 
Catalyst Technologies has set growth targets 
of high single-digit increases in sales in the 
short term, accelerating to mid-teens sales 
growth over the medium to long term. We 
expect mid-teens operating margin by the 
end of 2024/25, high teens by the end of 
2027/28, and continued accretion beyond 
as the business benefits from increases in 
technology licensing.
In Hydrogen Technologies we have scaled 
back our investment in line with the slower 
pace of hydrogen and fuel cell market 
development. The global hydrogen value 
chain is in an early stage of development 
and continues to evolve with customers 
reducing near-term demand expectations. 
As a result, whilst construction of our new 
plant in Royston is substantially complete, 
we are delaying the start of production in 
line with market development. We continue 
to de-risk our Hydrogen Technologies 
investment through reducing operational 
expenditure, seeking appropriate 
Government incentives and co-investment 
opportunities. Hydrogen Technologies sales 
increased by 31% this year and, although 
we expect slower growth in sales in the 
coming years, we are expecting the business 
to break even by the end of 2025/26.
A platform for future growth
PGM prices have reduced very significantly 
in recent years. We expect prices overall 
to be more stable in the future, thereby 
having a smaller impact on our results 
and cash flow. With further benefits 
of transformation, we expect at least 
mid single digit growth in operating 
performance at constant precious metal 
prices and constant currency this year.
Our balance sheet remains strong, with net 
debt slightly down year-on-year. Our aim is 
to maintain a strong balance sheet and 
closed the year at the lower end of our 
target level of net debt to EBITDA of 1.5-2.0 
times. We remain highly disciplined in our 
capital allocation: we will invest for growth 
and attractive returns, with a focus on core 
activities where we believe we can win. 
Beyond this our priority is to ensure a 
reliable dividend, targeting a 40% pay-out 
ratio over the medium term. We may 
consider acquisitions but will be highly 
selective, with a focus on bolt-on deals to 
acquire technology or accelerate growth 
in our core growth businesses. And finally, 
we would look to return excess capital to 
shareholders, as we plan to with the 
disposal proceeds.

Clean Air
Improved profitability driven by efficiency benefits
•	 Sales up 2% reflecting higher volumes partly offset by lower pricing
•	 Underlying operating profit increased 26% and margin expanded 190 basis points 
to 10.6%, with a significant improvement half on half (1H: 9.6% and 2H: 11.6%). 
This mainly reflected efficiency benefits and higher volumes, partly offset by lower pricing
•	 Delivered £2.0 billion¹ of cash from Clean Air in the three years since 2020/21, of which 
around one quarter relates to precious metal prices. Upgraded cash target and now 
expecting to deliver at least £4.5 billion of cash in the decade to 2030/31² (previously

Clean Air provides catalysts for emission control after-treatment systems used in light and 
heavy duty vehicles powered by internal combustion engines.
Overall, sales in Clean Air were up 2% with growth in our light duty and heavy duty diesel 
businesses partly offset by light duty gasoline. We benefited from higher volumes – 
particularly in light duty diesel driven by market share gains in China and North America. 
Despite benefits from commercial excellence initiatives including inflation recovery and 
further claims for non-inflation related activity, pricing was lower overall.
Sales 
Light duty diesel
In light duty diesel, sales grew 5% outperforming the market which saw a modest decline 
overall. This largely reflected our strong performance in Asia – particularly China – and also 
in the Americas against a backdrop of weaker market production. In Europe, our 
performance was slightly behind the market.

Other information

In Asia, we significantly outperformed the market which saw mixed performance across the 
region. We saw good performance in China driven by market share gains following recent 
wins and the ramp up of platforms. In India, we also saw good performance reflecting the 
ramp up of new platforms. 
In the Americas, we outperformed the market which was impacted by economic uncertainty. 
Our performance was driven by market share gains and platform ramp ups.
Light duty gasoline
Light duty gasoline sales were down 6%, underperforming the global market which grew well.
Our performance was mainly driven by Asia where we were impacted by the loss of platforms 
in previous years as well as mix effects. In Europe, whilst we benefited from a robust market 
and saw modest share gains, this was partly offset by lower pricing. In the Americas we 
underperformed the market reflecting the loss of platforms from previous years. We expect 
this to be the last year where we experience the effect of these historic platform losses.
Heavy duty diesel
In heavy duty diesel, sales were up 2% although behind the market. By region, we saw strong 
growth in Asia which was partly offset by lower sales in Europe and the Americas.
In Asia, growth was led by China and India. In China, we benefited from a market recovery 
following a weaker prior year with demand impacted by COVID lockdowns. In India, we saw 
good performance partly reflecting higher sales for off-road applications. In the Americas, 
our sales were broadly in line with a slightly weaker market. This year, Class 8 truck 
production was higher than anticipated reflecting a robust economy and strong order 
backlogs but the macroeconomic outlook in South America impacted production in the 
region. In Europe, we underperformed a growing market due to lower demand from our 
customers. Looking forward, our strong presence in heavy duty positions us well for 
upcoming advancements, such as internal combustion engines powered by hydrogen. 
Underlying operating profit
Underlying operating profit increased 26% and margin expanded 190 basis points  
to 10.6%, with a significant improvement half on half (1H: 9.6% and 2H: 11.6%).  
This mainly reflected efficiency benefits and higher volumes. Despite benefits from 
commercial excellence initiatives, we were impacted by lower pricing partly related  
to historical contract commitments.
Cash generation
We delivered another year of strong cash, generating around £600 million¹. In the three 
years since 2021/22, we have delivered a cumulative £2.0 billion¹ cash, of which around one 
quarter relates to precious metal prices.
PGM Services
Performance reflects lower average PGM prices 
•	 Sales declined 17% primarily due to lower average PGM prices
•	 Refinery volumes were lower due to continued softness in auto scrap recycling. 
This was partially mitigated by higher industrial and mining intakes
•	 Underlying operating profit declined 35% driven by lower average PGM prices and reduced 
volumes, partly offset by a continued focus on efficiencies and metal recoveries from 
asset renewals

PGM Services is the world’s largest recycler of platinum group metals (PGMs). This  
business has an important role in enabling the energy transition through providing  
circular solutions as demand for scarce critical materials increases. PGM Services provides  
a strategic service to the group, supporting Clean Air, Catalyst Technologies and Hydrogen 
Technologies with security of metal supply in a volatile market, and the manufacture of  
value-add PGM products. 
Sales 
In the year, sales declined 17%. This was primarily driven by lower average PGM prices, 
particularly palladium and rhodium which declined 38% and 64% respectively compared to 
2022/23. As the year progressed, average PGM prices stabilised with second half pricing 
below the levels of the first half. 
In our refineries, intake volumes were lower as previously guided due to less auto scrap. 
However this was partially mitigated by increased industrial and mining intakes where we 
applied our PGM refining expertise to handle highly complex feeds. Sales were lower in our 
metal trading business due to reduced PGM prices and volatility. Across our PGM products 
business, sales were broadly flat with higher demand for pharma products driven by business 
wins which offset cyclical declines in agrochemicals.
Underlying operating profit
Underlying operating profit declined 35% mainly impacted by lower average PGM prices 
(£85 million impact) as well as reduced volumes. This was partly mitigated by a continued 
focus on efficiencies, as well as metal recoveries from asset renewals.

Catalyst Technologies is a key pillar of our strategy as we target high growth, high return 
opportunities in the decarbonisation of fuels and chemical value chains. We have leading 
positions in syngas – methanol, ammonia, hydrogen and formaldehyde – and a strong 
sustainable technologies portfolio. Our revenue streams are licensing process technology 
and supplying catalysts.
Sales 
Sales were up 6%. We saw good growth in Catalysts – which represents the majority of  
sales – and strong growth in Licensing, up 20%. In Catalysts we benefited from higher  
pricing as we strengthened our commercial focus. Alongside better mix this more than  
offset lower volumes.
Catalysts: higher pricing and better mix offsetting lower volumes
Catalysts sales were up 4%. Growth was largely driven by formaldehyde following increased 
demand for biodegradable plastics in China. We also saw higher pricing across the portfolio, 
particularly in ammonia and hydrogen, and a better mix in additives. These benefits more 
than offset lower volumes, which were mainly driven by short-term cyclical weakness – 
primarily in methanol – and an unplanned shutdown at one of our plants. We expect the 
plant to be back in operation in summer 2024.
Licensing: early sales from our sustainable solutions portfolio
Licensing sales were up 20%. We saw strong growth in areas including oxoalcohols and 
methanol, following recent project wins in China. In our existing core portfolio, we signed 
eight licences in the period, worth around £110 million in sales over five years 
(2022/23: six licences). In our sustainable technologies portfolio, we recognised early sales 
from low carbon hydrogen and sustainable fuels. These sales doubled in the period albeit 
off a low base. 
Underlying operating profit
Underlying operating profit was up 56% to £75 million and the margin grew 390 basis points 
to 13.0%. This was largely driven by higher pricing reflecting our strong commercial focus, 
better mix and efficiency benefits.
Hydrogen Technologies
Strong sales growth and disciplined investment to scale the business
•	 Sales up 31% driven by higher volumes for strategic customers in fuel cells
•	 Underlying operating loss reflects investment to scale the business 
•	 Reducing investment and managing cost base with the pace of market development

In Hydrogen Technologies, we provide components across the value chain for fuel cells 
and electrolysers including catalyst coated membranes (CCMs) and membrane electrode 
assemblies (MEAs). Our ambition is to be the market leader in CCMs, which are the critical 
performance defining components at the centre of fuel cells, focusing on PEM (proton 
exchange membrane) and AEM (anion exchange membrane) electrolysers.
Sales
In the year, sales in Hydrogen Technologies were up 31% to £71 million driven by demand 
from our strategic customers. However, sales growth in the second half slowed as the market 
began to soften and our customers started to reduce inventories. This largely reflects a lack of 
clarity around regulation and incentives, slowing the development of supply chains and 
infrastructure.
Our continued focus on operational improvement and manufacturing efficiency drove 
significantly higher output from our UK plant in Swindon, enabling the vast majority of 
customer demand to be satisfied from this facility. As the market develops, our ability to 
continue making operational improvements will be vital in ensuring we have the agility to 
scale in line with market demand.
Underlying operating loss
Underlying operating loss of £50 million reflects investment into building capability and 
product development. Towards the end of the year, we took actions to reduce our cost base 
as we adapted to the softening market.

Corporate
Corporate costs were £82 million, an increase of £14 million from the prior year, 
largely reflecting higher costs in relation to the implementation of new IT systems.
Research and development (R&D)
R&D spend was £204 million in the year. This was down from £213 million in the prior 
year and represents c.5% of sales excluding precious metals. We are prioritising spend 
in our growth areas and are pursuing a very focused innovation strategy for Catalyst 
Technologies and Hydrogen Technologies. We are also investing in our digital capabilities 
to accelerate innovation and provide greater insights to our customers.
Foreign exchange 
The calculation of growth at constant rates excludes the impact of foreign exchange 
movements arising from the translation of overseas subsidiaries’ profit into sterling. 
The group does not hedge the impact of translation effects on the income statement. 
The principal overseas currencies, which represented 78% of the non-sterling 
denominated underlying operating profit in the year ended 31st March 2024, were:

For the year, the impact of exchange rates decreased sales by £120 million and underlying

If average exchange rates for May month to date (£:US$ 1.26, £:€ 1.17, £:RMB 9.10) are 
maintained throughout the year ending 31st March 2025, foreign currency translation will 
have an adverse impact of £4 million on underlying operating profit. A one cent change in 
the average US dollar and a ten fen change in the average rate of the Chinese renminbi have 
an impact of approximately £1 million on operating profit whilst a one cent change in the 
average rate of the Euro has approximately a £2 million impact on full year underlying 
operating profit.
Efficiency savings
In the year, we delivered c.£75 million of savings through our group transformation 
programme and incurred cash costs of c.£55 million. Cumulative benefits from the 
programme to date are c.£120 million. Reflecting our good progress, we have upgraded 
our cost savings target to £200 million by the end of 2024/25 (previously in excess of 
£150 million). 2024/25 will be the final year of the programme, after which we will focus  
on continuous improvement. Total associated costs to deliver the programme are around 
£130 million (previously around £100 million), all of which are cash.

There was a net charge of £148 million relating to major impairment and restructuring 
charges, comprising £78 million of restructuring costs and a net impairment charge of 
£70 million. The restructuring costs were recognised in relation to both our transformation 
programme and the consolidation of our Clean Air manufacturing footprint. The net 
impairment charge includes an impairment of our Battery Systems business to its fair 
value ahead of its disposal, as well as impairment charges relating to the recent slowdown 
in growth within the hydrogen and fuel cell market which required us to adapt to the 
changing demand profiles of our customers as they navigate this short-term uncertainty.
The £9 million loss on disposal of businesses largely comprises transactional costs in the year 
relating to the disposal of our Value Businesses.
Finance charges
Net finance charges in the period amounted to £82 million, up from the prior year charge of 
£61 million largely reflecting higher average borrowings and a higher interest rate environment.
Taxation 
The tax charge on underlying profit before tax for the year ended 31st March 2024 was 
£68 million, an effective underlying tax rate of 20.8%, up from 19.3% in 2022/23. 
This largely reflects the mix of profit across geographies.
The effective tax rate on reported profit for the year ended 31st March 2024 was 34.4%. 
This represents a tax charge of £56 million, compared with £80 million in the prior period.
We expect modest upward pressure to the effective tax rate on underlying profit for the year 
ending 31st March 2025 as territories in which we operate increase their domestic Corporate 
Tax rate in response to the OECD Pillar 2 rules.

Post-employment benefits
IFRS – accounting basis
At 31st March 2024, the group’s net post-employment benefit position, was a surplus 
of £117 million.
The cost of providing post-employment benefits in the year was £53 million, up from 
£40 million last year. 
Capital expenditure
Capital expenditure was £390 million in the year, 2.0 times depreciation and amortisation 
(excluding amortisation of acquired intangibles). In the period, key projects included:
•	 PGM Services – investing in the resilience, efficiency and safety of our refinery assets
•	 Hydrogen Technologies – investing in our manufacturing facility in Royston, UK, 
although delaying the start of production to align with market development.
Strong balance sheet
Net debt as at 31st March 2024 was £951 million, a decrease from £1,023 million 
at 31st March 2023 and £1,044 million at 30th September 2023. Net debt is £19 million 
higher when post tax pension deficits are included. The group’s net debt (including post tax 
pension deficits) to EBITDA was 1.6 times (31st March 2023: 1.6 times, 30th September 
2023: 1.7 times), which was at the lower end of our target range of 1.5 to 2.0 times.
We use short-term metal leases as part of our mix of funding for working capital, which are 
outside the scope of IFRS 16 as they qualify as short-term leases. Precious metal leases 
amounted to £197 million as at 31st March 2024 (31st March 2023: £138 million, 
30th September 2023: £186 million). 
Free cash flow and working capital
Free cash flow was £189 million in the year, compared to £74 million in the prior year, 
largely reflecting lower precious metal working capital partly offset by lower net proceeds 
from disposals.
Excluding precious metal, average working capital days to 31st March 2024 increased 
to 60 days compared to 42 days to 31st March 2023. This largely reflected lower average sales 
through the period as well as lower VAT payables and higher working capital to support our 
growth businesses. 
Outlook for the year ending 31st March 2025
For 2024/25, on a continuing basis excluding Value Businesses, we expect at least 
mid single digit growth in underlying operating performance at constant precious metal 
prices and constant currency.
In Clean Air we expect modest growth in operating performance, with continued margin 
expansion driven by efficiency benefits. Beyond this, with the impact of historical platform 
losses behind us, we expect further growth in operating performance and margin expansion. 
PGM Services’ operating performance is expected to be broadly stable, with limited impact 
from precious metal prices. In Catalyst Technologies we expect further strong growth in 
operating performance, with mid-teens margins. In Hydrogen Technologies we now expect 
modest sales growth, with a significantly lower operating loss as we manage our investment 
with the pace of market development1.
If precious metal prices and foreign exchange rates remain at their current levels2 for the 
remainder of 2024/25, we expect an adverse impact of c.£5 million to full year operating 
performance compared with the prior year.3, 4
Dividend
The board will propose a final ordinary dividend for the year of 55.0 pence per share 
at the Annual General Meeting (AGM) on 18th July 2024. Together with the interim dividend 
of 22.0 pence per share, this gives a total ordinary dividend of 77.0 pence per share, 
maintained at the same level as the prior year. Subject to approval by shareholders, the final 
dividend will be paid on 6th August 2024, with an ex-dividend date of 6th June 2024.
1.	 Outlook commentary for Clean Air, PGM Services, Catalyst Technologies and Hydrogen Technologies refers to underlying operating performance, and assumes constant precious metal prices and constant currency.
2.	 Average precious metal prices and average foreign exchange rates in May 2024 (month to date).
3.	 If precious metal prices remain at their current level for the remainder of 2024/25 there would be a benefit of £1 million on full year operating performance compared with the prior year. A US$100 per troy ounce change in the average annual platinum, 
palladium and rhodium metal prices each have an impact of approximately £0.5 million, £1 million and £0.5 million respectively on full year 2024/25 underlying operating profit in PGM Services. This assumes no foreign exchange movement.
4.	 At average foreign exchange rates for May 2024 month to date (£:US$ 1.26, £:€ 1.17, £:RMB 9.10) translational foreign exchange movements for the year ending 31st March 2025 are expected to adversely impact underlying operating profit by £4 million.

Our sustainability targets for 2030
For over 200 years our expertise in metal chemistry has helped to solve some of the world’s most complex challenges such as air pollution, and now our technologies are accelerating 
the transition to net zero1. 
Our sustainability targets for 2030 are ambitious, but they build off the incredible impact our products and services already have. Our technologies are now helping the global chemical 
industry reduce its GHG emissions and move to sustainable feedstocks, and our business model is underpinned by our circular PGM economy that helps reduce waste and make the most 
of scarce resources. 
Our GHG reduction targets for 2030 have been approved by the Science Based Targets initiative (SBTi) thereby putting us on the SBTi’s 1.5°C trajectory and placing us among the leading 
group of global businesses aiming for a rise of no more than 1.5°C.

Our company purpose is to catalyse the 
net zero transition because we believe 
this represents the biggest benefit 
we can bring to society. Sales of our 
products and services, when used by 
our customers, will bring about millions 
of tonnes of GHG avoided. We are also 
committed to net zero by 2040 for 
our operations.

Our goal: Drive lower 
global greenhouse gas 
(GHG) emissions
To drive our positive contribution to climate 
protection, we set ourselves the target that 
JM technologies will contribute towards 
avoiding 50 million tonnes1,2 of GHGs 
entering the atmosphere per year by 2030, 
compared to conventional technologies 
in 2020. This is equivalent to avoiding the 
emissions from half of UK transport3. Over 
the past year, we have signed significant 
licences and partnerships in key technology 
areas contributing to this goal, such as 
licences for production of low-carbon (blue) 
hydrogen, and for the production of 
sustainable aviation fuel. This financial 
year we achieved a significant milestone 
in avoiding over 1 million tonnes of GHG 
emissions. The target is largely reliant 
on our growth businesses of Hydrogen 
Technologies and Catalyst Technologies.
Sustainability Accounting Standards Board 
(SASB) Resource efficiency indicator: We 
have identified our revenues that align with 
the SASB Chemicals Sustainability 
Accounting Standard’s definition of 
products that, when used, improve energy 
efficiency, eliminate or reduce GHG 
emissions, reduce raw materials 
consumption, lower water consumption 
and/or increase product life. In 2023/24, 
those sales were £0.84 billion (with sales 
excluding precious metals as £3.90 billion) 
compared with £0.97 billion4 in 2022/23. 
This reduction is mainly due to reduced 
demand in the secondary PGMs market see 
pages 20-21 for more details.

Scope 1 and 2: Initial focus on energy efficiency, 
purchase of renewable electricity, further 
electrification of our operations and use of 
low-carbon fuels. For the longer term, we have 
started to scope harder-to-abate process emissions.
Scope 3: Reduction in Category 1 purchased goods 
and services through local and secondary sourcing, 
optimisation of supply chain packaging and 
transport, and operational efficiency. Our near-term 
target is on our most material category but we report 
on, and seek ways to reduce, all Scope 3 categories.
Business growth: JM’s capital investments are 
designed with net zero front of mind, based on 
agreed engineering sustainability principles. 
Our R&D organisation is applying its expertise to our 
manufacturing processes looking for opportunities 
to eliminate GHGs at the source.
Offsetting: We aim to significantly reduce our carbon 
footprint, and work with our suppliers to reduce 
theirs, without relying heavily on offsetting to reach 
our net zero targets. We continue to monitor the 
voluntary carbon market for opportunities to invest 
in high integrity projects in the future.

Planet: Protecting the climate
Ensuring a just transition to net zero
JM believes that we should decarbonise  
the economy whilst ensuring that no one  
is left or pushed behind. Being as fair 
and inclusive as possible to everyone 
affected will increase the chances of 
long-term success and sustainability 
of the energy transition.
We consider fully the risks and 
opportunities of all aspects of our 
plans and the impact on our various 
stakeholders. For example, through 
strategic supplier relationships, operating 
with a strict code of conduct and due 
diligence, we are increasingly creating 
opportunities for collaboration. We will 
continue to disclose risks identified in our 
supply chain and the action plans we 
develop. And we have strong connections 
with our local communities, ensuring 
both the company and our employees 
contribute actively to local initiatives. 
See page 51 for more information 
on how we are engaging with our 
communities
In order to meet the opportunities 
created by the global energy transition, 
we have to transform JM (see pages 8-9). 
Whilst this transformation will bring 
many new employment and career 
opportunities for current and future 
employees, inevitably some roles will 
change significantly or indeed 
cease to exist. 
For example, during 2023/24 we 
completed the full closure of two of  
our Clean Air plants to optimise our 
manufacturing footprint: Clean Air 
Royston in the UK and Germiston in South 
Africa, impacting around 800 employees 
in total. In addition to these two closures 
we also consolidated our production sites 
in Shanghai, China from two to one, 
and sold our plant in Krasnoyarsk, Russia. 
We supported the affected employees 
with help in finding alternative 
employment, either in JM or elsewhere. 
This included CV clinics, retirement 
workshops, counselling assistance, 
financial advice, and support in finding 
alternative employment. In Royston, out 
of 400 colleagues, we were able to find 
alternative roles for 90. Over 100 
colleagues found employment elsewhere 
during the process. Over a third of our 
Germiston employees had secured 
alternative employment at the time 
of the plant closure.
Our progress in 2023/24 
We continue to deliver on our roadmap to 
net zero1 by 2040. This year saw an 18% 
reduction in our Scope 1 and 2 greenhouse 
gas (GHG) emissions from last year, which 
represents a 30% reduction since our 
baseline year of 2019/20. This significant 
reduction was achieved mainly through 
increasing our purchase of renewable 
energy, in line with our energy strategy, 
and we have also improved the underlying 
energy efficiency of a number of processes.

Strengthening partnerships 
throughout the value chain
JM became a member of Together 
for Sustainability (TfS), a flagship 
initiative launched by companies in 
the chemical industry that helps drive 
sustainability in our supply chain 
through collaboration.
We continue our collaboration with 
the Carbon Disclosure Project (CDP) 
Supply Chain. In the past year we  
engaged with our biggest suppliers 
representing 85% of our annual 
spend to better understand their 
carbon footprint and net zero plans.
This year our Winter Energy Taskforce 
became a cross-functional Energy Risk 
Steering Committee, to manage the 
long-term energy strategy for JM, which 
is to increase our proportion of net zero 
carbon energy procured through 
opportunities which drive cost stability, 
energy security and resilience. 
Renewable energy
This year 57% of our electricity 
consumption came from certified 
renewable sources, compared to 41% in 
2022/23. This significant increase was due 
to renewable energy purchases in the 
regions of North Macedonia, India and 
China. We are therefore on track to achieve 
our ambition of purchasing 60% of our 
electricity from certified renewable sources 
by 2025. 
This year we created a JM Renewable 
Energy Standard to provide clarity on our 
position and strategy for renewable energy 
sourcing, and a hierarchy of preferred 
solutions to inform decision-making for our 
operations and procurement teams. We use 
green tariffs to ensure renewable electricity 
consumption in Europe and the US, and 
recognised Energy Attribute Certificates in 
regions such as India and China. Longer 
term we will focus on Power Purchase 
Agreements in regions where this 
procurement option is available. We 
continue to benefit from some on-site 
generation as part of the current energy 
portfolio in a number of sites, and further 
investment in our Taloja, India site this year 
has added 44,198 kWh capacity of self-
generated solar energy.
To increase our ambition we agreed a new 
target aiming for 90% of our electricity from 
certified net zero carbon sources by 2030.

Energy efficiency and security
A focus on energy conservation and energy 
efficiency continues to underpin our net 
zero strategy. We continue to implement 
ISO 50001 across our most energy-intensive 
manufacturing sites, using the energy 
management framework developed and 
introduced to our site teams last year. 
Examples of energy efficiency projects 
completed this year include:
•	 Further adoption of waste heat 
recirculation, with savings achieved at 
Clean Air sites in Poland, India and China
•	 Improved control has enabled expansion 
of the low temperature hot water 
network to provide heating for 
laboratories at one of our UK sites
•	 Reducing the idle time of one of our 
electric induction furnaces
For our engineering and capital projects 
we have developed sustainable engineering 
principles and applied a rigorous assessment 
process for all capital project investments, 
such as asset renewal and growth projects. 
For example, replacing steam boilers to best 
in class burner design at one of our UK sites, 
has resulted in lower energy use (and lower 
NOx emissions).
Three of our largest manufacturing sites 
also make electricity using combined heat 
and power plants (CHPs) to optimise our 
energy efficiency. Although these run off 
natural gas, our CHPs generated 
36,313 MWh of our total electricity this 
year, reducing our energy demand.

Our goal: Conserve 
scarce resources
We helped create one of the world’s first 
circular economies in platinum group 
metals and our increasing use of secondary, 
or recycled, Platinum Group Metals (PGMs) 
is helping to significantly reduce the 
emissions and environmental impact 
associated with mining these vital materials, 
see pages 20 and 21 for more details on 
secondary PGMs.
We are also applying our longstanding 
recycling expertise to sustainable 
technologies that utilise PGMs, such as  
fuel cells and electrolyser stacks. We are 
upgrading our infrastructure to allow us  
to recover and refine the PGMs used in 
these technologies to a very high purity in 
the same way we do today with production 
scrap. This will allow us to create a 
continuous loop of PGM availability for the 
hydrogen product economy.
Our performance in 2023/24
We set a 2030 target of 75% recycled PGM 
content in our products, and in 2023/24 
this number was 69%. As existing secondary 
routes decline, e.g. automotive market, 
and new technologies have yet to establish 
these routes, we may see declines in 
recyclable material rates, until routes for 
the new products, e.g. hydrogen fuel cells, 
are developed. 
Closing the PGMs loop to meet our 
customers’ evolving sustainability demands 
remains our driver, and will play an 
important role in the transition to net zero. 
In 2023/24 we achieved several milestones 
which will further enable this ambition. 
•	 Our methodology for specific customers 
across JM to purchase 100% recycled 
PGM content has been reviewed and 
accepted by the Carbon Trust as being 
in line with industry recommendations. 
In our PGM refinery process we mix 
secondary and primary metal feeds, so 
there is no way to physically distinguish 
the origin of the metal in the output. 
Now we can offer 100% recycled metal 
to specific customers through our mass 
balance approach. 
•	 We have applied our recycling expertise, 
and upgraded our infrastructure, to allow 
us to recover and refine the PGMs used in 
emerging technologies, such as fuel cells 
and electrolyser stacks. Our new 
HyRefineTM technology integrates both 
the PGM catalyst and catalyst coated 
membrane (CCM) manufacturing 
processes. We believe this is the first 
demonstration of circularity for the PGM 
and the ionomer together. This enables 
us to provide our customers with a full 
service offering. Please see page 21 for 
more details.
In 2023/24 we set up a voluntary employee 
network of Sustainability Champions. 
They are employees engaged and 
passionate about sustainability. 
Supported by the central sustainability team 
our champions are already working locally 
on initiatives, and going forward we want 
to maintain a balance of corporate 
involvement with a bottom-up approach 
to sustainability. Impact on nature is by 
definition a local issue, and this network 
provides that grass-roots view of where the 
risks and opportunities are.

Catalysing 
the net zero

In 2023/24 we developed and ratified 
a new Nature strategy. We commit to 
promoting nature protection, restoration 
and sustainable use of natural resources. 
Our corporate commitments are 
described in our new Nature statement, 
found at matthey.com
Circularity is an essential part of the net 
zero transition, and as the world’s largest 
secondary PGM refiner we will play a 
crucial role in securing the metal needed 
to supply existing and future demand.

Our goal: Minimise our 
environmental footprint 
We are committed to protecting the 
ecosystems around our sites and minimising 
all our potentially harmful interactions. 
Our global environmental, health and safety 
(EHS) policies, processes and management 
system help us to maintain a high level of 
environmental performance. All our sites are 
assessed against these standards by our 
centralised EHS audit team at least once 
every three years. 93% of our manufacturing 
sites use environmental management 
systems that are certified as meeting 
ISO 14001 standard, as at 31st March 2024.
Minimising waste: reduce, 
reuse, recycle 
We are committed to minimising waste 
generation and recycling as much as possible. 
Our operations create waste, which is always 
treated in line with local regulations. But 
beyond that we are committed to disposing 
of it responsibly and in a safe manner, 
working with specialist treatment companies. 
The ongoing investment planned in our 
new PGM refinery in the UK will be a 
significant project towards meeting our 2030 
target on hazardous waste reduction. We are 
always looking for ways to reduce waste at all 
of our sites. For example, last year at our site 
in Smithfield, the US we upgraded our NOx 
abatement system. This year the new system 
has demonstrated not only a reduction in our 
emissions, but it also made a significant 
reduction in hazardous waste on site, 
expecting to reduce hazardous waste 
in JM by 2% and reduce JM’s waste 
to landfill by 19%.
Total waste sent off site has increased  
this year by 4% compared with last year 
mainly due to decommissioning of 
manufacturing facilities.

We continue to work with third-party waste 
providers, looking for opportunities to divert 
our waste away from disposal.
We have established processes to recover 
PGMs from our production waste and 
subsequently recycle in our own refineries.
Using water responsibly
This year our Oberhausen site in Germany 
managed to reduce their water consumption, 
which will result in a 50% reduction in their 
annual water consumption going forward, 
through collaboration with the downstream 
effluent treatment system operator. 
To understand where we need to act most 
quickly for most benefit, we use the World 
Resource Institute’s (WRI) Water Risk Atlas 
tool to analyse usage at our sites. This year the 
tool identified 12 manufacturing facilities 
which are located in regions with a high or 
extremely high baseline water stress level. 
This means that they are at higher risk of 
declining water availability or increased cost 
in the future due to drought or groundwater 
table decline. The 12 manufacturing facilities 
accounted for 402,254 m3 (23%) of our net 
freshwater consumption in 2023/24. 
We discharged 1.2 million m3 wastewater 
during the year, 96% to municipal 
treatment plants and the remainder back 
to its original freshwater source after 
treatment. We treated 0.9 million m3 of 
wastewater on site, of which we recycled 
33% back into our manufacturing processes 
instead of discharging.
We seek to minimise the chemical burden 
in our wastewater discharged. 
Reducing emissions to air 
Some of our operations produce other air 
emissions as by-products of chemical reactions, 
including nitrogen oxides (NOx), sulphur oxides 
(SOx) and volatile organic compounds (VOCs). 
All our permitted sites monitor these emissions 
to ensure they comply with local regulations.
This year we saw a further decrease in our 
year-on-year NOx emissions due to the 
enhanced NOx abatement system at our 
Smithfield site, US, delivering improved NOx 
removal efficiency. Capital investment to 
replace steam boilers to best in class burner 
design, at one of our UK sites, has also 
resulted in a reduction in NOx emissions.
We don’t produce ozone-depleting 
substances (ODS) through our operations, 
however, any small leaks of refrigerant gases 
are reported in our Scope 1 GHG emissions.

Per- and polyfluoroalkyl 
substances (PFAS)
We are aware of the increasing levels of 
concern over potential risks posed by a 
subset of PFAS entering the environment 
and are committed to reducing our uses, 
developing alternatives, better 
understanding and limiting impacts on 
human health and the environment from 
PFAS in our operations and products. 
An exciting demonstration of this is our 
new HyRefine™ technology that delivers 
circularity for the PGMs as well as the 
valuable ionomer components in fuel cell 
and water electrolysers, at end-of-life. 
We continued to work directly with 
suppliers, customers, trade bodies, NGOs 
and regulators to ensure responsible use 
and proportionate regulations of PFAS. In 
2023 JM actively contributed, individually 
and as part of various trade bodies, to the 
EU consultation on the PFAS restriction 
proposal; UK PFAS policy options; and to 
the US proposals under the Comprehensive 
Environmental Response, Compensation, 
and Liability Act (CERCLA). 
Biotechnology in JM
We continue to invest in growing our 
biocatalyst product-offering and 
manufacturing capabilities, within our Life 
Sciences Technology business. Biocatalysts 
deliver sustainability and safety benefits to 
traditional catalysts, such as requiring less 
energy intensive reaction conditions and 
reduced need for organic solvents. Our 
biocatalysts are manufactured using 
genetically engineered microorganisms. 
None of our biocatalyst products contain 
live organisms at the point of supply to our 
customers, and they currently represent just 
0.02% of our sales. 
See matthey.com/sustainability for 
more information
Planet: Protecting nature and advancing the circular economy
Product stewardship 
throughout the value chain
The nature of the complex chemistry in our 
products and manufacturing processes 
means that we sometimes have to use 
chemicals that are potentially hazardous. 
JM’s product stewardship processes, and our 
commitment to Responsible Care®, a global 
initiative of the chemical industry, are 
central to ensuring our products should not 
pose any risk to humans or the environment 
when used responsibly and as intended, and 
that we comply with all relevant laws and 
regulations. We require the same of our 
suppliers, see our Supplier Code of Conduct, 
supporting them when we identify 
deficiencies in e.g. hazard classifications or 
regulatory compliance. Our customers can 
access support on how to handle and 
dispose of our products safely, beyond what 
we provide in our safety data sheets, via 
published guides and direct engagement 
with product specialists. In the event of an 
incident with a JM product, a 24-hour 
global emergency response telephone 
service is in place to provide safety 
information in the local language. This year, 
we received no reports of significant health 
effects from the use of our products, and we 
continue to comply with all applicable 
health and safety, labelling and marketing 
regulations, and voluntary codes.

Our goal:  
Keep people safe
The nature of our business means we have 
complex chemical processes that often 
involve heavy machinery and hazardous 
chemicals. Our ability to catalyse the net 
zero transition depends on the mitigation 
of potential risks and the safe operation 
of our manufacturing sites. 
Take 5 is one of our key global 
environmental, health and safety (EHS) 
programmes and continues to drive global 
improvements in health and safety 
performance. During 2023 we ran a 
campaign that focused on our key risk areas 
such as hand cuts, sprains and strains. 
We also created a Centre of Expertise in 
Industrial Hygiene by centralising industrial 
hygiene resources so that these can be 
deployed more effectively to where the risks 
are across the group.
In terms of regional EHS performance we 
have initiated a project to review and 
improve safety at our facilities in the North 
America region. A local team comprising 
operations and EHS managers has developed 
an improvement plan that addresses 
common safety issues at our US facilities, 
including ergonomics, job risk analysis and 
competency. The project leaders report 
progress to the Group Operations Leadership 
Team on a quarterly basis.
Three of our businesses have introduced 
site-specific improvement plans for the 
small number of sites that drive their 
lagging indicator performance. These plans 
are currently ongoing and are reviewed by 
the business unit leadership team.
Our occupational health and 
safety performance
Lost time injury and illness rate (LTIIR) 
reduced from 0.24 last year to 0.17. In our 
total recordable injury and illness rate 
(TRIIR), for employees and contractors, 
we went from 0.47 to 0.36 this year which 
is a 23% improvement. This is a 
demonstration of the effectiveness of our 
Take 5 programme and the impact of our 
annual Global Safety Day, as well as 
additional local campaigns at site level 
which have focused on site-specific safety 
issues. We have had no fatalities since 2015.
We continue to embed process safety 
training across JM. In the last five years 
process safety training has been completed 
by over 3,000 operations-based staff, plus 
in-depth training for over 700 managers 
and senior executives. We have also 
completed individual process safety 
competency assessments for 305 managers 
and engineers in process safety-critical roles 
at facilities rated as ‘high hazard’ with an 
ongoing programme of assessments for 
new starters.
All of our high hazard facilities have now 
been subject to a formal corporate EHS 
audit within the last three years and a 
process safety audit within the last five years.
Global Safety Day 2023
This year’s event focused on Taking 5 
Together, with the theme ‘It’s In Our Hands’ 
designed to encourage employees to feel 
empowered to take responsibility for their 
own safety and that of their colleagues. 
JM teams, globally, dedicated a day to 
safety, attended workshops, made personal 
safety pledges and celebrated successes. 
Our employees across all sites and offices 
took part in safety-related activities that 
really brought to life the importance of us 
all being accountable for safety. 
Helping people to feel healthy, 
secure, supported and 
connected
We have a wellbeing strategy in place to 
support all employees and help them focus 
on four wellbeing pillars: physical, financial, 
social and mental health. Employees are 
provided with Elements, a personalised web 
platform and app to access wellbeing 
resources and support. This includes an 
employee assistance programme (Assist) 
which provides confidential counselling for 
mental health and work-life services. See 
page 48 for more details.

Our process safety performance 
Our International Council of Chemicals 
Association (ICCA) process safety event 
severity rate (PSESR) has decreased from 
1.02 last year to 0.88 PSESR per 200,000 
hours worked. There were three Tier 11 
process safety events this year, compared 
to nine the previous year. We have 
improved the governance process for our 
high risk process safety scenarios and there 
has been great progress in reducing the 
number of open scenarios. With the 
creation of new engineering teams at group 
level and in the businesses, we now have a 
joint EHS and Engineering working group 
to understand better ways of working to 
effectively address implementation of 
process safety requirements at site level 
such as asset integrity and installation of 
modern automated control systems.

Secondly, we updated our performance 
management approach during the year with 
a focus on delivering ongoing dialogue 
around expectations, forward-focused 
feedback and development. We now require 
all our managers to hold regular feedback 
and performance discussions with their team 
members. The new approach has been well 
adopted, and employees report they are 
having better ongoing dialogue, with 
improved quality of feedback, recognition 
and development conversations.
We have also built on our digital recognition 
platform, Say Thanks, where colleagues can 
send appreciation through an eCard or 
nominate significant contributions for awards. 
Supporting our people’s professional and 
personal growth remains at the core of our 
commitment as an employer. During 
2023/24 we took several initiatives to 
support this, including strengthening our 
succession planning into critical leadership 
roles, ongoing investment in the future 
pipeline of leaders through our graduate 
programmes, various talent accelerator 
programmes, and broad development 
initiatives such as customer-centricity 
training, business skills programmes, 
and the implementation of a new global 
digital learning platform, Percipio.
To support and reinforce all these initiatives 
we are now supplementing our revamped 
annual employee survey with quarterly 
all-company pulse survey check-ins, 
ensuring that all our managers are 
proactively leading their teams through 
change whilst providing ongoing feedback, 
recognition and development.

A high-performance culture is critical to the 
execution of our strategy. We are making 
good progress in creating a more market-
focused, agile and less bureaucratic 
company, where our people can be truly 
customer-centric and thrive in their roles. 
Building an engaged,  
high-performance culture
At our launch of the ‘Play to Win’ strategy in 
2022, we identified three aspects of our 
culture that we needed to enhance:
Engagement score 
improved from 6.9 in 
March 2023 to 
7.2 
in January 2024 (on a 
scale from 1-10)
“Taking action from 
last survey” score 
improved
+0.8 
(on a scale from 1-10) 
from March 2023 to 
January 2024
Say Thanks: 
84% 
of all employees in JM 
have accessed the portal 
and employees have 
received three recognition 
moments on average 
through the year
It is critical that our leaders – at all levels – 
in JM take the lead in accelerating this 
throughout the organisation. This year we 
established a series of ‘Play to Win Through 
People’ workshops for managers across the 
entire organisation to give them the tools 
to bring the strategy to life with their teams, 
to clarify expectations on them as 
managers, and to build their skills 
and confidence to drive performance, 
employee engagement and change.

Advancing diversity, inclusion 
and belonging
Performance and innovation require diversity 
of thought, background and representation 
as well as a culture of inclusion and 
belonging. This year we have taken strategic 
and practical steps to ensure our diversity, 
inclusion and belonging (DI&B) journey is 
meaningful and has long-lasting impact. 
We have continued to drive activities in line 
with our DI&B roadmap to progress towards 
achieving our sustainability goal, targets 
and commitments. 
See our Diversity, Equity, Inclusion and 
Belonging Policy, matthey.com/DIEB
Developing and attracting talent
Our female representation at all 
management levels2 is 30%, an 
improvement on last year’s 28%, and a step 
forward towards our target of 40% by 2030, 
with a milestone of 31% in 2025. 
Our Talent Acquisition team and DI&B team 
have continued to build partnerships with 
organisations such as the Society of Women 
in Engineering, Women in Chemicals and 
Association for Black and ethnic minority 
engineers to ensure we can source and 
attract the best talent from a range of 
diverse backgrounds in the market. 
In 2023/24 we formed a partnership with 
STEM Returners, a leading organisation in 
the UK in returner programmes, to help 
STEM professionals return to work after a 
career break. To date, we have six returners 
in the business in engineering, legal and 
procurement with all returners now being 
offered either extended contracts or made 
permanent employees. 
Once we have recruited talented people 
into the business, providing the right 
environment for all to progress through the 
organisation and reach their full potential 
is critical. In September we launched our 
‘Elevating women in leadership’ pilot 
programme, and to support the 
development of our Black, Asian and ethnic 
minority employees, we continued to 
participate in the Black British Business 
Awards talent acceleration programme 
in the UK and the McKinsey connected 
leadership development programme 
in the US.
Earlier this year, we ran a diversity data 
campaign across our senior leadership to 
better understand the ethnic representation 
of this population. 
In line with the Parker Review 
recommendations, we have set 
targets to improve senior 
representation for minority 
ethnic individuals, targeting 
15% 
representation in our senior 
management by 2027, based 
on our current representation 
of 9%. 
Included in this 2027 target is 
a separate target for Black 
representation of 
3%
Sustainability continued
We continued to create awareness around 
our DI&B agenda and build confidence in 
speaking about difference, with our nine 
employee resource groups remaining at the 
core of this work. We also implemented a 
new DI&B events structure to better engage 
our employees. This resulted in widely 
attended local events and webinars with 
external and internal speakers for 
International Women’s Day, LGBTQIA Pride 
Month, Hispanic Heritage Month, Black 
History Month, and International Day of 
Persons with Disabilities, along with the 
creation of our first Global Inclusion Day. 
Disability inclusion
Last year, we conducted a site accessibility 
audit which resulted in a recommendation 
to provide all customer-facing staff with 
disability equality and awareness training, 
specifically including deaf awareness. 
Our DI&B and Learning and Development 
teams engaged an external partner to 
design some disability inclusion training, 
which we piloted with our Royston, UK 
reception staff. We then worked on a train 
the trainer model to allow us to roll out the 
training across JM for all employees in a 
customer-facing role.

Fair pay
We operate a ‘total reward’ approach at JM, 
and we aim to provide a total reward 
offering that is flexible, market competitive 
in each country in which we operate and 
affordable for JM. For this, we are 
committed to providing fair reward that 
is consistent with our goal of being an 
inclusive and sustainable company.
We understand that there is pressure on our 
people’s finances because of the current 
economic environment and for the second 
year in a row, we have given a larger 
portion of the global salary budget to 
non-management roles, recognising that 
cost-of-living pressures are felt more 
acutely here.
We are developing our approach to global 
pay transparency in line with EU legislation 
and have already disclosed our UK gender 
pay gap report in accordance with UK law. 
In 2023/24 our UK gender pay gap was 
7.6% which puts us ahead of the national 
average of 14.3%. 
In addition to our employees’ pay, we have 
provided support through an employee 
assistance programme (Assist), which 
provides JM employees and dependants 
with confidential, external professional 
advice on a variety of financial wellbeing 
topics such as debt management, 
mortgages, and loans, in addition to 
broader mental, physical and social 
wellbeing topics. Our temporary employees 
received the same benefits as our 
permanent employees.

Parental leave
We recognise the significance to our 
employees of starting and supporting 
a growing family. To support employees, 
we maintain a Global Parental Leave 
Standard. This standard provides a global 
minimum standard of 16 weeks fully paid 
leave for new parents (including adoptive 
parents) who are regarded as the 
primary caregiver.

Freedom of association
We respect and uphold the freedom 
of association and the effective recognition 
of the right to collective bargaining. 
In 2023/24 a quarter of our people globally 
were covered by collective bargaining 
agreements and/or represented by works 
councils or trade unions.
Regular engagement is undertaken directly 
with our employee representative groups 
on a range of topics including freedom 
of association and collective bargaining. 
These groups include recognised trade 
unions, or elected employee representative 
groups where trade unions are not present. 
The engagement is conducted on a regular 
and routine basis to ensure employee 
representative groups are well informed 
across a range of business and people- 
related topics. Several of our transformation 
initiatives have been guided and subject to 
thorough collaboration and consultation 
with employee representatives to ensure all 
relevant aspects are covered and managed.

People: Promoting a safe, diverse and equitable society 
Upholding human 
rights and high ethical 
standards
We support the principles of the Universal 
Declaration of Human Rights and the 
International Labour Organisation (ILO) 
Core Conventions. We are aligned with key 
frameworks that define human rights 
principles for businesses, including UN 
Guiding Principles on Business and Human 
Rights and the Organisation for Economic 
Co-operation and Development (OECD) 
Guidelines for Multinational Enterprises. 
Our approach to human rights considers 
our entire value chain, including our own 
operations, suppliers, partners and 
customers. We have set ourselves a 
commitment to assess all of our value chain 
partners for human rights risks by 2030.
matthey.com/human-rights-policy
Our operations
Our Human Rights policy sets out our 
commitments and provides for regular 
processes to identify and mitigate risks 
in our operations. Where we have operating 
sites in high-risk countries we work with 
local teams to implement remedial actions 
where required.
Our suppliers and customers
We initiated a human rights risk assessment 
for suppliers accounting for 85% of our 
annual procurement spend (excluding 
PGMs). Utilising the EcoVadis IQ Module, 
we rated 529 suppliers, with 5% identified as 
(very) high risk. We are working with these 
suppliers to address these risks effectively.
Where required, mitigations and remedial 
actions have been put in place and continued 
monitoring has been implemented. 
We actively engage and support our 
suppliers on their sustainability journey. 
Last year we reported the case of a supplier 
in a higher risk region that we were working 
with to improve their EcoVadis assessment, 
following a human rights assessment.  
As a result the supplier has this year 
achieved a silver medal for their 
commitment to sustainable and  
responsible business practices. 
For Ecovadis KPIs of our suppliers see our 
Sustainability Performance Databook, 
matthey.com/sustainability-databook
This year we included detailed human rights 
expectations into our updated Supplier Code 
of Conduct as well as our standard Terms 
and Conditions of Purchase and template 
purchasing agreements. These require 
our suppliers to not only comply with all 
applicable human rights laws, but also to put 
robust internal procedures in place to mitigate 
and remediate human rights risks. These 
obligations apply both to our direct suppliers, 
existing and new, as well as their supply chain 
and subcontractors.
See our refreshed Supplier Code of 
Conduct, matthey.com/supplier-code
We also work closely and collaboratively 
with our customers to provide open and 
transparent disclosure. We see our customers 
as valued partners and we contribute to their 
sustainability goals by actively engaging and 
providing data and information about 
climate-related, human rights, diversity and 
governance topics. Our commitment extends 
to informing them about our sustainable 
practices in both our products and 
operations, ensuring transparency in all 
sustainability developments concerning JM. 
Moving forward, our dedication remains 
unwavering as we strive to enhance our 
engagement with customers, empowering 
them to make informed choices that play 
a crucial role in shaping a more sustainable 
and resilient future.
Modern Slavery Statement
We are committed to ensuring no modern 
slavery exists in our business and to identify, 
mitigate and remediate any issues we find 
in our value chain. We publish our Modern 
Slavery Statement annually to demonstrate 
our progress.
matthey.com/modern-slavery
Doing the right thing underpins 
everything we do
Our new, refreshed and simplified digital 
Code of Ethics, called ‘Doing the Right 
Thing. Together.’ is a practical guide for us 
all to use. It provides guidance around four 
key areas applicable to everyone:
1.	What doing the right thing means and 
our Code commitments 
2.	Making good, ethical decisions
3.	Asking for help when you are unsure 
what to do; and
4.	How to speak up with serious concerns
Included within is a new decision-making 
tool, which assists anyone facing an ethical 
dilemma or difficult decision. Our global 
network of ethics ambassadors is called out 
as an on-site resource should employees 
have ethical queries or concerns. And we 
have included a people manager section, 
highlighting the role and responsibilities 
line managers have in promoting an ethical 
culture within their teams across JM.
To complement our refreshed Code of 
Ethics we rolled out a new programme  
of ethics training globally. We also run 
bespoke training courses for specific  
groups, for example on competition  
law and anti-bribery and corruption  
for externally facing employees.  
This year we also rolled out a human rights 
training course to targeted groups.
See our full set of policies on our website
For details of training courses see our 
Sustainability Performance Databook, 
matthey.com/sustainability-databook
Our Speak Up culture 
Our independent Speak Up helpline is available 
for anyone wishing to raise a concern.
We analyse Speak Up metrics quarterly to 
identify key themes and significant trends 
and share these with the Societal Value 
Committee and relevant senior leaders. 
See page 89 for more information 
about our Societal Value Committee
During the year there were 138 Speak Ups, of 
which two related to bribery and corruption. 
JM has a zero-tolerance approach to bribery 
and corruption, and our Ethics & Compliance 
team thoroughly investigated to determine 
whether the allegations could be proven or 
whether any recommendations should be 
made, as it does with all categories of Speak 
Ups. Even where allegations of bribery and 
corruption are not proven, an assessment is 
made to ensure the risk of bribery and 
corruption taking place in the future is 
properly mitigated. During the year no legal 
cases regarding bribery and corruption were 
brought against JM or its employees.

Responsible sourcing
Our global multi-tiered supply chain 
encompasses a wide range of suppliers 
providing raw materials, goods and services. 
We foster a responsible and sustainable supply 
chain by collaborating closely with our 
suppliers. In 2023/24 our supplier spend was 
£3 billion (excluding precious group metals).
In 2023/24 we developed responsible sourcing 
principles. Led by our commitment to creating a 
positive impact through our operations, the 
responsible sourcing principles embody our 
dedication to ethical and environmentally-
conscious practices across our value chain. 
All new suppliers receive and acknowledge the 
refreshed Supplier Code of Conduct which 
includes an environmental section. 
We also conducted a review of our Scope 3 
emissions from purchased goods and services, to 
map existing decarbonisation commitments 
from suppliers and identify additional levers to 
reach our 2030 target. This work will help us 
prioritise our engagement with suppliers, and 
guide our work with initiatives such as Together 
for Sustainability, to ensure we maximise the 
positive impact we can have on our supply chain.
We continue our partnership with Tealbook 
and Minority Supplier Development UK 
(MSDUK). In the next year we aim to use 
MSDUK to help us set a long-term supplier 
diversity strategy and target. We have 
estimated that 3% of our spend with suppliers 
is allocated to diverse or small businesses, and 
we identified several opportunities to improve 
our sourcing practices to be more inclusive as 
well as enhance our internal training and 
adoption of the programme. We are also 
embedding the Tealbook services into our 
conversations with customers and suppliers 
and update them on the diversity spend.

and have now exited Russia completely.
Several raw materials to our products, 
including PGMs, rare earth metals and 
zeolites, are sourced from China. No major 
concerns have been identified, however, 
we continue the process of reviewing the 
detailed due diligence templates and will 
implement mitigations or put remedial 
actions in place, as required.

with suppliers to get information on 3TGs 
(tin, tantalum, tungsten and gold) and 
cobalt in our products.
Of the 3TGs, tungsten is used in our 
autocatalyst products, though we recognise 
we may have small amounts of the others in 
finished goods and refining intakes. We 
have identified 85 suppliers providing 3TGs 
and cobalt going into our products. These 
suppliers have each provided due diligence 
industry standard reporting templates,  
of which four did not fully meet our 
requirements due to low supply chain 
coverage (less than 75%). We are working 
with these suppliers on remediation plans.

Being a responsible neighbour continues 
to be core to our community investment 
approach. Through our activities we aim 
to strengthen the communities surrounding 
our sites by contributing to their long-term 
resilience and sustainability, and in 
particular by removing barriers to 
STEM education.

Tackling STEM inequality 
We remain committed to working with local 
partners and schools to tackle STEM 
inequality and break down barriers young 
people often face in accessing quality STEM 
education and opportunities.
Our global community impact programme, 
Science and Me, enables us to make 
progress in this area by contributing to 
projects with funding, expertise and time. 
Science and Me has been fostering curiosity 
and stimulating an interest in STEM since 
launching three years ago. 
In 2023, Science and Me awarded grants 
for new projects in the US, UK and North 
Macedonia. North Macedonia 2025, for 
example, aims to enhance access to quality 
STEM education for 15 primary schools across 
North Macedonia by delivering hands-on 
learning experiences that will inspire around 
1,500 students and 25 science teachers. Since 
its inception, our Science and Me programme 
has awarded a total of 30 grants to help tackle 
STEM inequality.
We launched a pilot with Tent Partnership 
for Refugees with sites across the UK, 
Sweden and Germany, enabling our people 
to volunteer by taking up mentorship roles 
supporting refugee women back into work. 
Empowered by a sense of communal 
responsibility, our colleagues in 
China and Japan responded to local 
natural disasters by donating funds 
and relief supplies to the victims.
The annual Poland Business Run 
saw 220 colleagues globally run 
a combined total of 880km in 
support of a non-profit, raising 
funds and awareness for people 
with disabilities. 
Our teams in China mobilised 
over 320 colleagues to support 
nature conservation initiatives, 
promoting the preservation of 
Chongming island’s ecosystem.
45 colleagues from eight UK 
locations participated in the 
Peak District Ultra Challenge, 
raising £25,000 for 27 
charities, which was doubled 
through our match funding 
scheme.
35 colleagues from our 
Wayne and Devon sites 
helped clean up trash and 
debris from a local 
watershed, helping protect 
the local ecosystem.
In response to the conflict impacting 
Israel and Gaza, we donated to 
Médecins Sans Frontières (MSF) 
Doctors Without Borders, funding 
emergency medical care where it is 
most needed.
11 Science 
and Me 
grants 
were awarded in 2023, to five 
non-profits and six schools, engaging 
nine JM sites in three countries.

How we engage with our 
external stakeholders 
As a global company with a leading role  
in the net zero transition, we engage 
actively with non-profit organisations, 
policy makers, business associations and 
global alliances. This helps ensure we 
maximise our positive impact on society,  
by playing our role in developing 
sustainable solutions, and setting the  
right sustainability objectives. 
Throughout the year, we attended flagship 
events and debates to keep up to date with 
the latest sector trends and rapidly evolving 
regulatory landscapes. For instance, we 
were present at COP28 to follow the climate 
negotiations and to enable better 
understanding of the role that our solutions, 
such as sustainable aviation fuels and clean 
hydrogen, can play in the journey to net 
zero. We attended several conferences to 
share insights on our key markets, such as 
the World Hydrogen Leaders conference, 
ADIPEC and the London Platinum Week. 
Business associations and  
non-profits
We actively engaged with business 
associations last year. For instance, we 
worked with the Association for Emissions 
Control by Catalyst (AECC) on the 
introduction of Euro 7 standards in the EU 
and on other regulations promoting clean 
air and sustainable mobility solutions. We 
also engaged with Hydrogen Europe and 
the Hydrogen Council to provide expert 
insight on hydrogen technologies, as well as 
on the PGM markets, to inform policy and 
support the critical role of PGMs in the 
energy transition. 
We also joined the Industry Council of the 
US Department of Energy’s Energy 
Innovation Hub. We will help inform the 
Critical Materials Innovation Hub’s five-year 
programme on PGMs, using our unique and 
longstanding depth of knowledge across the 
entire PGM ecosystem.
In addition, we engaged with several 
non-profit organisations and think tanks on 
sustainability topics, including our Nature 
strategy, JM Renewable Energy Standard, 
and how to best embed sustainability in our 
capital investments. 
We provided insights to the British Society 
of Chemical Industry (SCI) on the business 
case for an industrial science and innovation 
strategy in the UK, underpinned by 
sustainability, which was used in their 
Manifesto released in August.
Global alliances
JM is a member of global alliances which 
can help drive business outcomes and  
shape the low-carbon markets we play  
in. For instance, we are actively involved  
in the World Economic Forum’s Securing 
Minerals for the Energy Transition initiative, 
where we provide expert insights on the 
supply and demand of the PGM market, 
including the key role of the secondary 
market and their contributions to 
sustainable technologies.

Introduction
Climate change is one of the most 
pressing threats facing our planet today. 
We recognise that what we do at Johnson 
Matthey has impacts – both positive and 
negative. Our solutions help our customers 
to reduce greenhouse gas (GHG) emissions 
and the new technologies we are designing 
will help further accelerate the transition 
to a low-carbon future. But our operations 
have their own environmental impact, 
creating GHG emissions, using water 
and producing waste.
Our business strategy is shaped around 
the opportunities and the risks that our 
changing climate presents. We have set 
ourselves the target of achieving net zero 
by 2040; our Scope 1, 2 and 3 long-term 
target ambition has been recognised as 
aligned with the SBTi’s 1.5°C mitigation 
pathways. 
The disclosures in this report are consistent 
with the TCFD recommendations.
Governance
Given the nature of our business, 
and how closely aligned our strategy 
is to a warming world, climate-related 
risks and opportunities have been 
on the board’s agenda for many years.
Role of the board and its 
committees
The board is responsible for setting and 
overseeing the implementation of the 
group’s strategy, including the annual 
budget and detailed business plans. 
In doing so, it considers climate-related 
issues, including when approving requests 
for capital expenditure or new initiatives.
The responsibilities of the board and its 
committees in relation to climate-related 
issues and the broader sustainability agenda 
are set out in our Matters Reserved for the 
Board and in our Audit Committee and 
Societal Value Committee (SVC) Terms 
of Reference. 
See the Matters Reserved for the Board 
and Terms of Reference for our 
committees within the Corporate 
Governance Framework document on 
our website: matthey.com/governance 
The SVC focuses more closely on the 
governance of sustainability matters, 
including our response to climate change. 
The SVC meets three times a year, see pages 
89 to 91 for composition and more 
information about its work in 2023/24. 
Together with the Nomination Committee, 
the board ensures that, among the 
directors, it has the necessary sustainability 
and climate-related expertise.
For more details of our non-executive 
directors’ skills and experience, see 
pages 77-79
The Audit Committee monitors and assesses 
the level of assurance over TCFD and 
climate-related issues and performance 
metrics. The committee is also responsible 
for reviewing the effectiveness of internal 
control and risk management, which 
includes climate-related risk.
The Remuneration Committee set 
three ESG targets within the group’s 
Long-term Performance Share Plan (PSP): 
two climate related targets and a DI&B 
target. Our senior leaders and directors 
participate in this PSP. This clearly reflects 
our intent to contribute to an acceleration 
of the transition to a net zero world and 
creating a diverse, inclusive and engaged 
company. Details of the PSP targets set 
for 2024 can be found on page 127.
Role of management
The board delegates responsibility 
for running the business to the Chief 
Executive Officer (CEO); this includes 
overall responsibility for climate-related 
issues. The CEO is supported by the Chief 
Sustainability Officer (CSO) and the 
Sustainability Managers who together 
develop our sustainability vision, 
goals and targets.
The CSO is responsible for prioritising our 
sustainability agenda and threading all 
elements into our business, providing 
updates to the Group Leadership Team 
(GLT) on the steps taken to develop or 
implement our sustainability strategy, 
including key metrics, risks, opportunities 
and our roadmaps to net zero by 2040. 
At a business level, there are work 
streams for advancing specific aspects 
of sustainability.

on a concerted approach.
Strategy
Our business strategy is based on our 
purpose of catalysing the net zero transition 
for our customers through enabling the 
necessary transitions in energy, chemicals 
and automotive, underpinned by circularity. 
Climate change offers us many business 
growth opportunities through our products 
and services, as well as some risks. However, 
the pace at which the world will adapt to 
the impacts of climate change is uncertain. 
So that we properly understand and are 
resilient to these uncertainties we maintain 
climate-change scenarios to frame the 
ambiguities in our long-term business 
strategy of an increasingly volatile and 
complex environment.
Climate scenarios for evaluating 
transition risks and opportunities
Our climate scenarios are used by all our 
businesses as a common basis for planning, 
forecasting and stress testing their strategy 
and assumptions on growth. These 
scenarios, which project the impact of 
climate change on our operational and 
commercial performance, are essential in 
informing our strategic decisions, such as 
how we invest in R&D and assets, or which 
new products to develop. We also use 
climate scenarios to consider the resilience 
to changing weather patterns of our own 
operations, those of our strategic suppliers 
and our core supply routes.
Our three transition scenarios represent 
three global temperature rise pathways.
•	 Rapid transition scenario (aligned to 
1.5°C) – net zero achieved globally by 
2050, in line with the goal of the Paris 
Agreement to limit the world’s 
temperature rise to well below 2°C above 
pre-industrial levels and pursue efforts to 
limit the temperature increase to 1.5°C. 
This reflects swift and decisive action 
regarding policy interventions and 
decarbonisation commitments.
•	 Pragmatic evolution scenario (aligned 
to 2°C) – net zero achieved globally 
by 2080, which reflects a step-up in 
policy interventions and decarbonisation 
commitments compared with today, 
but not as decisive as under the rapid 
transition scenario.
•	 Slow transition scenario (aligned to 3°C) 
– net zero not achieved by 2100, 
reflecting a global lack of urgency on 
climate change with limited policy or 
legislative interventions.

Task Force on Climate-related Financial Disclosures continued
We developed our climate scenarios 
internally, with support from external 
experts, and also using the latest available 
research from the International Energy 
Agency (IEA). The IEA inputs included three 
scenarios: the Net Zero Emissions Scenario 
(supporting our Rapid Transition scenario), 
the Announced Pledges Scenario 
(supporting our Pragmatic Evolution 
scenario), and the Stated Policies Scenario 
(supporting our Slow Transition scenario). 
Our methodology breaks down the different 
energy sources (electricity, hydrogen, gas, 
coal, oil, renewables, biomass and others) 
and considers forecasts for each source by 
demand type: transport, buildings, industry, 
power and heat. We developed in-house 
forecasts for specific source / demand 
combinations close to our areas of expertise 
in automotive, chemicals, hydrogen and 
other industries, while ensuring that, at a 
macro level, we remained within IEA’s 
forecasts. During the last year we have also 
started to link availability of critical raw 
materials to our scenarios, since this will 
likely have a significant impact on the rate 
of the clean energy transition progresses, 
and allows us to consider risks associated 
with both direct access to such materials 
and potential geopolitical impacts to 
such access.
We update our scenarios at least annually  
to reflect changes in external drivers, 
incorporating the latest from internationally 
recognised sources alongside our own 
forecasts. Our updates in the last year  
point towards an acceleration in demand 
for clean hydrogen in the medium to long 
term across scenarios, both for direct use 
and in producing sustainable fuels for  
both aviation (SAF) and maritime (clean 
ammonia and methanol), reflecting  
policy mandates and targets. 
For example, during the past year, 
the International Maritime Organisation 
significantly increased its emissions 
reduction ambitions, from a 50% reduction 
by 2050 (compared to the 2008 baseline 
year) to an intention “to reach net-zero by 
or around, i.e. close to, 2050”. We are also 
seeing increased focus on the potential for 
hydrogen-powered aviation in the longer 
term (post 2035), both using hydrogen 
in internal combustion engines and 
in fuel cells.
We model scenarios up to 2100, but look 
at shorter-term horizons, specifically 2030 
and 2040, to inform our strategic and 
operational decisions. In the shorter term 
we also consider the impact of factors such 
as higher interest rates and current lack of 
policy clarity, on the ability of projects to 
move towards a Final Investment Decision, 
which can impact near-term energy 
transition developments. The table below 
details the main qualitative and quantitative 
assumptions we used for our 2040 
scenarios. We use the Pragmatic evolution 
scenario as our base case for our 
strategic planning.

Climate scenarios for evaluating 
physical risks
Changing weather patterns as the climate 
warms may result in physical risks to our 
assets and supply chains. We have evaluated 
the exposure of all our assets, with specific 
deep dives where needed, and those of our 
strategic suppliers to these risks.
We used the Shared Socio-economic 
Pathways (SSPs), the latest climate change 
modelling scenarios from the 
Intergovernmental Panel on Climate 
Change (IPCC). The SSPs produce forward-
looking climate data by running climate 
models driven by assumptions about future 
global GHG emissions, together with 
plausible future socio-economic 
development metrics (economic growth / 
GDP, demographics, land use and 
urbanisation), and incorporating the likely 
implementation of adaptation and 
mitigation measures. The three SSPs we 
considered, for the locations of all our own 
operations and those of our strategic 
suppliers, are shown in the table below. 
Four time horizons were considered – 2020 
(our baseline), 2030, 2040 and 2050 to 
identify the top hazards and how they are 
likely to change.
Scenario
Assumed temperature increase (relative to 1850-1900)
SSP 1-2.6
Best estimate of 1.7°C warming by 2041-2060, and 1.8°C by 2081-2100
SSP 2-4.5
Best estimate of 2.0°C warming by 2041-2060, and 2.7°C by 2081-2100
SSP 5-8.5
Best estimate of 2.4°C warming by 2041-2060, and 4.4°C by 2081-2100
SSP 5-8.5 is an extreme scenario that is unlikely to arise, but is useful for stress testing. 
We use it to test the resilience of our key sites.

Our climate-related transition risks and opportunities 
Through our scenario work, we identified three distinct potential climate-related impacts, which represent both risks and opportunities for our business. 
We use our climate scenarios to evaluate these risks and opportunities in the short (0–3 years), medium (3–10 years) and long term (10+ years), in line with our usual business planning 
timescales. We believe the Pragmatic evolution climate scenario is most likely to occur, so have used it as the base case for assessing our transition impacts, and the other two scenarios 
to stress test the sensitivity and resilience of our business plans

Our climate-related physical risks and opportunities
Changing weather patterns as the climate warms may result in physical risks to our assets and supply chains. They could damage our sites and disrupt production, leading to loss of sales and 
increased costs, as well as posing risks to our employees. They could also hamper our access to strategic raw materials through supply chain disruption, either at our suppliers’ sites or in transit. 
These physical risks can be grouped into two categories:
Acute, which are extreme events such as tropical cyclones, thunderstorms, severe flooding events, droughts, heatwaves and wildfires.
Chronic, which are gradual changes like rising sea levels that damage coastal property, or sustained changes to temperature and rainfall.

Risk management
All our climate-related risks are subject to our global enterprise risk management process, which provides a systematic approach of understanding, evaluating and addressing all identified 
risks (see page 63 for more information).
Task Force on Climate-related Financial Disclosures continued
Identifying climate-related risks
We continually review and evaluate our 
climate-related risks against industry best practice, 
peer benchmarking and risks identified by business 
leads and subject matter experts as well as new 
and emerging risks. 
We believe our climate risks are in line with industry 
and legislative expectations. 
Managing those risks
The Societal Value Committee (SVC) oversees our 
sustainability strategy, including managing our 
climate-related risks. These risks may have a direct 
or indirect impact on our Principal and Business risks, 
and are therefore managed alongside and integrated 
within the enterprise risk management process.
To drive consistency, each risk in our enterprise risk 
process, including climate-related risks, has been 
assigned a risk owner and sponsor. These individuals 
are senior stakeholders who are accountable for 
reviewing, monitoring and assessing the magnitude 
of the risk as well as overseeing the implementation 
of appropriate mitigations.
All of our principal risks are reviewed formally, 
twice a year, by the GLT and the Board. 
Assessing those risks
We also use external third parties to evaluate 
physical climate risks at our locations and those 
of our suppliers. With the four assessments 
conducted this year, we now have detailed site 
resilience assessments for five of our top ten 
highest risk manufacturing locations. This 
determines the requirements for areas we need 
to focus on in the short, medium and long term.
Integrating those risks
Through our enterprise risk framework, climate-
related risks and opportunities are integrated into 
our strategic decision-making. Climate change 
considerations are part of how we operate, and 
climate is included in our bottom-up operational 
risk management process, providing a clear view of 
climate-related risks across the organisation. For 
instance, Principal Risk 1 is directly related to the 
first transition risk identified as part of TCFD 
guidance – see page 64 for more details.

Internal carbon pricing (ICP)
We use a shadow carbon price in our capital investment business case assessment process. Although the ICP is not a real cost of the investment, it demonstrates what the impact would be of 
the carbon taxation forecast for 2030 and beyond, and we use it to evaluate and compare potential investments. We expect the ICP to play an increasingly important role in influencing our 
investment decisions, as carbon impacts come under increasing scrutiny from key internal and external stakeholders. 
We are using the ICP for Scope 1 and 2 emissions for the asset when operational, with the intention to extend this to Scope 3 in the future. We chose not to apply ICP to emissions related to 
the development of the project itself, such as equipment manufacture, or to construction-related emissions, since such emissions are both short term and generally minor in relation to the 
overall life of the asset. The price applied in 2023/24 was £100/tonnes CO2e, with sensitivity analysis conducted at £50/tonnes CO2e and £150/tonnes CO2e.

Risk report
Risk management is an essential 
and integral part of JM’s planning 
and decision-making. It is fundamental 
in helping us achieve our objectives, 
improve outcomes for our stakeholders, 
enhance the realisation of opportunities 
and support the growth afforded by our 
stated aim of being a market leader in 
energy transition solutions. During the year, 
we have refined our principal risks to 
enhance clarity and reflect our progress. 
Managing risks effectively
The ability to effectively manage the risks 
that we encounter plays a crucial part in 
strategic delivery and driving accountability. 
Risk management stands as a cornerstone 
of our governance and operations 
throughout the organisation. We continue 
to invest in awareness initiatives and the 
training of our employees to stay ahead of 
various threats. This intends to cover all 
areas of risk management, including cyber 
security and financial risks.
Financial risk management forms part 
of the group-wide risk management 
framework which adopts a top-down and 
bottom-up approach, to ensuring current 
and emerging financial risks are identified, 
understood and managed in line with our 
risk appetite. Functional leaders, businesses 
and site teams are responsible for 
identifying, assessing and prioritising their 
financial risks, considering the likelihood 
of occurrence and their potential impact 
on JM’s objectives. This includes reviewing 
whether a risk has changed, how effective 
the controls we use to manage the risks are, 
and whether mitigating actions are in place.

An annual review of fraud risks and the 
mitigation controls is performed by 
functional owners as part of the annual risk 
assessment process facilitated by our risk 
and compliance platform, JMProtect. A 
walkthrough within each key function is 
conducted to identify fraud risks and 
mitigating controls which are then captured 
in JMProtect with ownership assigned. 
Completion of remediating actions, 
including those identified through the 
independently run Speak Up process, 
is monitored regularly by internal 
governance bodies. Regular updates are

Risk management framework
Our risk management methodology 
identifies and considers principal risks, 
including severe yet plausible scenarios.  
Its purpose is to reassure stakeholders that 
we have fully considered and understand 
a broad range of risks and are managing 
them in line with defined risk appetites.
The board, which is ultimately accountable 
for risk management and internal controls, 
evaluates how effective these systems are at 
mitigating principal and emerging risks at 
least once every year. The GLT provides 
support for the board’s reviews, which 
ensures the risks we have identified are 
relevant to our current aims and strategic 
goals. The Audit Committee supports the

How we manage risk
We apply the three-lines-of-defence model as laid out in the diagram below.
Regulatory inspection bodies
External audit
board in assessing the effectiveness of our 
risk management and internal control 
systems, processes and policies.
Our risk management methodology takes a 
top-down approach to identify our principal 
risks (i.e. from board level down) and a 
bottom-up approach to identify operational 
risks (i.e. from day-to-day level up). 
We are constantly looking to improve 
how connected and aligned these 
approaches are as they operate in parallel.
Functions, businesses and site teams are 
responsible for identifying, assessing and 
prioritising their risks. They also consider 
how likely it is that a risk will materialise 
and what effect that would have on our 
objectives. This includes reviewing whether 
a risk has changed, how strong the controls 
we use to manage the risk are and whether 
mitigating actions are in place. We use 
self-assessment and management 
attestation processes to report, at least once 
a year, on whether the relevant controls are 
effective. This is a maturing process with 
several initiatives in progress to improve 
our controls environment.
In the past 12 months, we have continued 
to improve how we address and monitor 
risks in a number of ways, including:
•	 Making continued enhancements to  
our risk and compliance platform, 
JMProtect, which offers a combined  
and centralised view of our risk universe 
and controls framework.
•	 Developing our Aligned Assurance 
model that aligns second and third-line 
assurance activities for easier 
collaboration and more proportionate 
risk-based assurance.
Working closely with Group Insurance, 
JM prioritises insurance cover for the most 
significant areas of risk across the group, 
and areas where insurance is a legal or 
contractual requirement. If insurance is 
available on commercially reasonable 
terms, we also utilise it as a risk mitigation 
tool across our wider business. Where 
appropriate, we get advice from industry 
to help us assess risks and develop 
mitigation plans.

Principal risks and uncertainties
In the following section, we outline our 
principal risks, alongside the measures 
we have taken to reduce them. They are 
classified as principal risks because they 
could materially harm our company’s 
operations, either alone or in combination. 
We regularly review our risks to best 
determine key mitigating actions, while 
also assigning appropriate GLT sponsors to 
help us overcome our biggest challenges 
and continue to meet our strategic 
objectives. Our GLT sponsors work closely 
with principal risk owners to assess changes 
to their risks, better understand our 
exposure and create targeted mitigation 
strategies. Over the last year, we have 
continued to review and update our 
principal risks, clarifying associated 
opportunities and priority actions. 
The principal risks identified below are 
categorised as strategic or operational 
principal risks. Strategic principal risks, 
if handled effectively, carry a significant 
opportunity to deliver above stakeholder 
expectations. We recognise that risks 
present potential exposures that require 
effective risk management to control and 
treat the uncertainty. This effectiveness also 
provides opportunities to the business to 
have better strategic thinking that can 
provide financial and operational benefits.
We have added ‘Risk movement’ icons in 
the principal risk section. The icons show 
the risk movement from 2023 as illustrated 
in the previous year’s Annual Report.
Strategic and operational risks
To execute our strategy, we must be 
mindful of the risks that may undermine us, 
while ensuring we capture most of the 
opportunity they present. Our day-to-day 
operations carry a level of risk that must be 
managed effectively to ensure that we are 
able to keep our people safe and meet our 
strategic goals.

Risk 
movement
1. Market factors, customer demand and margin 
sustainability
GLT sponsor: Liam Condon, Chief Executive Officer
JM’s strategy is focused on developing solutions to support 
our customers through the energy transition, particularly 
in sustainable chemicals, fuels and energy.
The risk is that we fail to correctly anticipate and/or make 
the right business decisions to address shifts in demand 
for our products and services (e.g. driven by regulation, 
customer needs, societal expectations), or shifts that 
lead to margin erosion. 
Such shifts may impact existing and new products, and 
may create upside opportunity and downside exposure 
(e.g. from faster or slower energy transition).
If we correctly anticipate and respond to shifts, we can  
enhance value through increased revenues, profits and  
optimised resource allocation.
Subsequent to a reassessment of the risk exposure due to 
changing market conditions and the resulting risk 
movement, we are addressing this in the following ways:
•	 We systematically monitor market conditions, 
technologies and customer requirements to adapt 
our plans where needed.
•	 Margin sustainability is underpinned by our on going 
transformation program, and our continuous 
improvement mindset across the business.
•	 In addition, we further reinforce and assure margins by 
diversifying our customer base, improving our offerings 
through innovation and R&D, establishing strategic 
partnerships to secure offtake, and focusing 
on opportunities where we have significant 
competitive advantage.
Formerly ‘Significant shift in demand and/or 
commoditisation of sustainable technology’.

2. A significant geopolitical or macroeconomic  
event impacting JM’s operations
GLT sponsor: Louise Melikian, Chief Strategy and 
Corporate Development Officer
JM has a global business footprint, in terms of operations, 
customers and supply chains.
There is a risk that we face disruption due to geopolitical  
or macroeconomic events (e.g. from conflict, trade 
disputes, sanctions, pandemics, macroeconomic events,  
or financial crises).
Mitigating this risk helps avoid adverse impact on our 
people, sales, profits or investment. In addition, successfully 
mitigating this risk provides a level of competitive 
advantage by providing supply security for our customers.
•	 JM’s wide global presence and portfolio hedges 
our macroeconomic and geopolitical risk 
to some extent. 
•	 Our strategic planning considers macro and geopolitical 
risk when making investment decisions.
•	 In addition, we continuously monitor JM’s exposure 
across the countries and regions to which we 
are exposed.
•	 When needed, we set up taskforces to examine and 
address specific risks.
Louise Melikian has taken over 
as risk sponsor. 
Previously, JM saw potential for elevated 
geopolitical risks in serving and sourcing 
from China. We have since seen this risk 
abate somewhat, although we continue to 
monitor and take this risk into 
consideration while making decisions.
3. Failure to deliver business value from 
strategic capital projects 
GLT sponsor: Mark Wilson, Chief Executive,  
Hydrogen Technologies
The success of our strategy, especially in growth areas, 
depends on our ability to effectively prioritise and deliver 
our strategic capital investment pipeline. There is a risk 
that we will be unable to meet production capacity 
expectations, breach budgeted costs or lose our 
competitive position in markets.
Robust portfolio planning, management and governance, 
combined with enhanced competence in capital project 
delivery, will provide us with the platform we need to meet 
the growth ambitions of our growing businesses and 
deliver on our wider strategy.
Delivering high-priority projects on time, within budget 
and to benchmarked costs will enable JM to grow 
further and faster.
Subsequent to a reassessment of the risk exposure due 
to changing market conditions and the resulting risk 
movement, we are addressing this in the following ways:
•	 We continue to strengthen our central engineering and 
project organisation and address missing functional 
competency gaps.
•	 Plans are in place to embed project frameworks, with 
business-wide compliance as a key value driver and a 
foundation of governance.
•	 Mitigation plan includes transforming roles and 
confirming accountability of sponsors for project value.
•	 We are bringing a continuous improvement approach to 
our capital investments by incorporating learnings from 
previous capital projects, and ensuring historical weak 
points are addressed in the front end planning of new 
investments like the refinery investment in the UK.
•	 Integrated owner project teams with all key functions 
represented are being established.
•	 System performance is continuously being 
monitored, using key leading indicators and key 
performance indicators.
Mark Wilson has taken over as risk sponsor.
A priority focus has been bringing industry-
leading rigour to our front-end planning 
and evaluation of investment opportunities. 
We are embedding this through robust 
evaluation of our business needs and 
matching those needs with a project 
solution. As a result, our investment 
decision making will be improved, ensuring 
we are maximising the utilisation of our 
resources and focusing on the right 
growth opportunities.
We are making good progress in 
strengthening our capital projects execution 
capacities, especially as they apply to our 
most material and complex capital projects. 
We expect this risk to reduce further as gaps 
are closed and the long-term value of the 
new approach becomes apparent.

4. Development of offerings that do not  
meet the future needs of customers
GLT sponsors: Liz Rowsell, Chief Technology Officer, 
and Anish Taneja, Chief Executive, Clean Air and Chair 
of the Group Commercial Council
There is a risk that we are unable to develop offerings 
that are competitive enough to meet our market 
ambitions and the needs of customers, particularly in 
highly dynamic and emerging markets. This includes  
our ability to identify and understand customer 
expectations, translating this into effective innovation 
programmes and developing our technologies at 
industrial production scale.
A strong product portfolio, effectively designed in line 
with our customers’ current and future needs, will enable 
us to win in our chosen markets for the years to come.
Effective development of products and offerings will 
continue to improve our brand and enable us to win in 
new markets as they are identified.
Subsequent to a reassessment of the risk exposure due 
to changing market conditions and the resulting risk 
movement, we are addressing this in the following ways:
•	 We continue to foster strong connectivity across the 
value chain, involving customers and suppliers alike in 
innovation discussions.
•	 We differentiate our innovation portfolio management 
approaches to support both our mature and growth 
businesses appropriately. We leverage tools such as New 
Product Introduction to ensure effective delivery across 
the portfolio. Examples of such innovation has resulted 
in new products such as FT CANS™ technology and 
HyRefine™, our novel process for recycling both the PGMs 
and valuable ionomers from fuel cells and electrolysers.
•	 We are developing a stronger and more consistent 
OneJM view of the emerging landscapes in the energy 
transition, including technology scanning and scouting 
and proactive management of intellectual property in 
the new markets.
Formerly ‘Development of products that do 
not meet the future needs of customers’.
Liz Rowsell has assumed a role as joint risk 
sponsor alongside Anish Taneja.
We ensure we are resourced to maximise 
value from our core businesses whilst 
supporting growth by investing in the 
front-end strategic marketing, business 
development, technology development, 
manufacturing scale-up, and digital skills 
needed to win in the broader playing field.
5. A significant work-related EHS incident
GLT sponsor: Mark Wilson, Chief Executive, 
Hydrogen Technologies
The focus of this principal risk, related to Environmental, 
Health and Safety (EHS) performance, is around 
catastrophic incidents (e.g. fire, explosion or toxic gas 
release) due to process safety or major compliance 
failure which would threaten our critical operations, 
product portfolios or our corporate reputation and 
therefore our ‘licence to operate’. 
As we operate high hazard installations, our business is 
controlled by a wide range of challenging health, safety 
and environmental laws, standards and regulations, 
which are set by governments and regulatory agencies 
around the world.
•	 We have a strong health and safety culture across 
the group. This is based on clear policies, guidelines 
and standards, continual training and awareness 
activities and audits.
•	 A joint EHS and Engineering working group has been 
established to understand better ways of working to 
effectively address implementation  
of process safety requirements.
•	 We regularly review process safety hazards  
at relevant sites by carrying out deep-dive  
safety audits.
•	 We thoroughly investigate incidents or accidents to 
identify their root cause and then develop plans to 
remediate the problem.
•	 We monitor our environmental risk, report on 
environmental data associated with our sites and always 
look for opportunities to improve.
•	 We regularly review our regulatory and reputational risks 
and put mitigation plans in place where we need to. 
Over the past 12 months, we have improved 
governance on how open high-risk 
scenarios from process hazard reviews are 
managed. This is allowing a transparent 
picture of where each of the high-risk 
scenarios are so that they are better managed.
We have created a JM EHS operations 
council, which is a cross-business 
governance body comprised of Operations, 
EHS and Engineering leaders. It is 
accountable for EHS performance and for 
ensuring a strong safety culture is in place. 
The council plays a key role in assessing 
whether EHS risks are being managed 
effectively across the group through 
regularly reviewing EHS performance. 
Nevertheless, we continue to review any 
emerging EHS risks (especially process 
safety) across all our businesses, which 
we are fully evaluating and mitigating.

6. Disruption to provision of key goods  
or services by suppliers
GLT sponsor: Anish Taneja, Chief Executive, Clean Air 
and Chair of the Group Commercial Council 
As a global business, we are dependent on suppliers 
worldwide to provide key materials and services. Given 
the speciality nature of our products, there are limited 
suppliers who supply certain critical raw materials. 
If there was a significant disruption in their supply 
we would be unable to manufacture our products 
to satisfy customer demand. 
Our new growth areas (e.g. hydrogen, sustainable 
aviation fuel), are nascent industries, and supply chain 
infrastructures are immature. Ecosystems of suppliers 
are still fragile and vulnerable to market shocks 
and uncertainties.
•	 We ensure physical safety stock is available and review 
material lead-times to reduce the impact of any failure 
modes on our processes.
•	 We utilise market intelligence to drive early warnings 
and are developing statistical material stock 
management systems.
•	 We use a global category management approach and 
have started a process to reduce the number of suppliers 
in our tail spend areas.
•	 We continually review our supplier base according 
to our latest business strategies and ensure that our 
relationships with the key and high impact suppliers are 
rigorously managed.
Formerly ‘Disruption to inbound goods 
or services provided’.
The risk has decreased, reflecting the 
implementation of our refreshed JM strategy. 
A Fit to Win supplier base is at the centre 
of our new procurement vision to co-pilot 
business to deliver sustainable profitable 
growth. We have built the first Fit to Win 
2030 supplier base strategy with each  
JM business. 
Strategic supplier base shaping exercises have 
been completed with each of the JM 
businesses, and supplier segmentation and 
supplier action plans completed with our key 
suppliers. The global JM supplier convention 
has enabled us to bring our key relationships 
to the next level, with closer collaboration to 
anticipate potential supply chain disruptions 
and market trends.
7. A low-performing culture undermines 
our strategy
GLT sponsor: Annette Kelleher, Chief HR Officer
A low-performing culture characterised by an 
insufficiently engaged and inclusive workforce, lacking 
commitment to taking accountability, keeping it simple 
and driving results could impact on our ability to attract 
and retain key talent and therefore successfully execute 
our strategy.
A high-performance culture is essential to executing  
our strategy, delivering growth and being more  
efficient. High-quality leaders can build diverse,  
inclusive and engaged teams in which everyone 
can deliver better results.
•	 We are delivering a ‘Play to Win Through People’ 
campaign across JM to create a clear understanding of 
our people manager expectations and their importance 
in delivering our strategy.
•	 We are building commercial and engineering capabilities 
to ensure that we have quality leadership with 
appropriate skills to lead the execution of our strategy.
•	 Our global employee engagement survey is helping us 
measure the shift to ‘Play to Win culture’. Ensuring that 
everyone in our company can share their views.
•	 Engagement and Diversity, Inclusion & Belonging 
roadmaps are in place to create a highly engaged and 
inclusive environment. 
The risk remains unchanged. While there 
are signs of improved engagement 
from our surveys, we are still working 
towards simplification. 
As part of our commitment to a high-
performance culture, we have looked at 
different solutions that will help us improve 
the way we operate across our functions to 
make them fit for the future.
This has led to the strategic decision to 
introduce JM Global Solutions (JMGS). 
The intention is to reduce complicated 
processes that may slow us down and help 
impact the customer and employee 
experience in a positive way.

8. Breach to security or control of  
platinum group metals in our processes 
GLT sponsor: Alastair Judge, Chief Executive,  
PGM Services
JM uses significant quantities of high-value precious 
metals, which are transported, stored and processed 
across our operations. We do not carry significant 
exposure to price risk as we hedge our metal transactions 
centrally, looking at overall group supply and demand.
Our PGMS business ensures the group has sufficient metal 
to meet business demands and manages our metal 
liquidity levels. There is a risk that we do not have 
sufficient metal available. Therefore, we operate within 
tight trading limits and defined liquidity levels to manage 
the demand volatility. Metal price volatility affects how 
much our trading business earns. 
The precious metal industry globally is susceptible to 
criminal activity resulting in the risk of theft, and we share 
those challenges. Loss or theft due to a failure of metal 
controls (operations and finance) and/or security 
management systems associated with the protection 
of metal may result in financial loss and/or a failure to 
satisfy our customers, which could reduce our customers’ 
confidence in JM and lead to potential legal action. Failure 
to mitigate this risk can have a significant impact on our 
working capital, financial viability and/or undermine our 
ability to meet our customer commitments.
•	 Long-term strategic planning around the metal 
requirements of the group is undertaken to ensure 
appropriate positioning for the future. 
•	 We run a strong operational control environment within 
our metal trading business. 
•	 We hedge our metal transactions centrally through 
looking at the overall group supply and demand, 
minimising our exposure to metal price volatility. 
•	 We maintain a robust security management system 
to protect our metal holdings. 
•	 We have appropriate insurance cover in place.
Formerly ‘Security of metal and failure 
to manage metal commitments’.
The overall rating of the risk remains high 
due to the threats around metal theft. 
We have continued to strengthen physical 
security and the metal controls environment 
to ensure we have a proportionate control 
structure to manage and optimise our  
metal holdings.
9. Failure in one or more of JM’s  
critical operational assets
GLT sponsor: Alastair Judge, Chief Executive,  
PGM Services
A critical asset failure may have a material effect on our 
supply chains, performance, share value and reputation.
In addition to the failure of aged assets, we are exposed 
to the effects of climate change.
We understand that more frequent extreme weather 
events and natural disasters may disrupt our operations 
and increase our costs. 
•	 Our asset failure risk management process is being 
strengthened to calibrate rigour according to the 
criticality of assets and risk profile of sites.
•	 All JM manufacturing sites have been categorised as 
high, medium and low risk sites based on objective 
review of site hazards and strategic importance to JM. 
This will help prioritise resource and capital expenditure 
allocation for critical ageing assets.
•	 In line with the scenario-based risk analysis 
recommended by the TCFD, climate-related physical 
risk assessments have been completed at a number 
of identified sites.
The overall rating for this risk has  
not changed.
We continue to assess this risk based on the 
level of exposure across our businesses and 
their reliance on aged critical equipment. 
The implementation plan for enhanced 
processes is on track and improvement 
in risk exposure will be seen with the delivery 
of ongoing initiatives.

10. Unsuccessful delivery of key business 
transformation programmes
GLT sponsor: Peter Hill, Group Global Services and 
Transformation Director 
JM’s transformation is scoped to implement the strategy 
of catalysing the net zero transition for our customers 
in energy, chemicals and automotive. There are currently 
around 25 programmes, across group functions and the 
four core businesses, driving business growth, people 
growth and efficiency.
Failure to successfully deliver these programmes may 
delay the expected benefits, disrupt services to customers 
or trigger a loss of key talent. 
Together, the transformation programmes will address 
capability gaps and poor competitiveness in key markets. 
Through the transformation, JM will develop and 
strengthen its capability for ongoing continuous 
improvement, delivery of complex projects and agility 
to respond to future external trends.
•	 We have staffed and resourced all major transformation 
programmes with capable programme leads and subject 
matter experts. 
•	 We continue to coach and support programme teams 
to apply the JM Transformation Standard.
•	 Strong change management and  
communication plans are in place for major cross-JM 
programmes, such as the recent introduction of JMGS.
•	 We are identifying potential resource conflicts for 
programmes running concurrently and working with 
programme leads to resolve them. 
Peter Hill has taken over as risk sponsor. 
Over the past 12 months, we have 
established stronger programme 
and change management capability. 
By applying JM’s Transformation Standard, 
we expect to deliver benefits across the 
portfolio at or above target and reduce 
this risk in the coming year. 
11. Business failure through  
cyber-attack or other IT incidents
GLT sponsor: Stephen Oxley, Chief Financial Officer
A failure to adapt our Information Technology (IT) 
and Operational Technology (OT) to changing business 
requirements, the occurrence of significant disruption 
to our systems or a major cyber security incident may 
adversely affect our financial position, harm our 
reputation and could lead to regulatory penalties 
or non‑compliance with laws.
•	 We are driving investments in our IT and OT 
infrastructure to improve our resilience and increase 
operational efficiency.
•	 We deliver a range of employee awareness training 
to educate on cyber risks and safe working practices.
•	 We are enhancing our Global Cyber Security function and 
controls with the appointment of business-specific cyber 
OT risk champions and technical leads.
The overall rating for this risk remains high, 
reflecting the increasingly complex and 
heightened external threat landscape. We 
continue to manage this risk by enhancing 
cyber security technologies and processes, 
improving our ability to Identify, Prevent, 
Detect, Respond and Recover, aligned 
to our adoption of the NIST Cyber 
Security Framework.

Emerging risks and 
opportunities
We continually monitor our external risk 
landscape using a mixture of key risk 
indicators, third-party reports, findings from 
internal and external assurance providers, 
and feedback from both customers and 
suppliers. This information allows us to 
identify emerging risks and prepare 
reasonable mitigations. 
For any identified emerging risks, 
considered to be a threat to JM or its value 
chain, we tailor our response to the size 
of the risk to ensure our mitigation strategy 
is proportionate. 
In addition to risks continually monitored  
by businesses, functions and sites, we  
are paying attention to the following 
emerging risks:
1. Digital risks
JM is developing strategies to deal with risks 
and opportunities present in the digital 
space that require focus. With regards to 
generative AI, an AI Council has been 
formed with cross-business representation 
as well as the creation of an AI Policy to 
provide employees with high-level direction 
whilst the landscape evolves. The aim of the 
Council is to evaluate opportunities from 
multiple angles including business 
enablement, commercial risks, personal 
data concerns as well as JM’s ethical 
approach to the use of AI and the potential 
impact on resources.
Our businesses continue to assess and plan 
what is required to move into the next 
phases of digitisation for JM. There are 
several legacy systems which will require 
upgrades and digitisation to aid the speed 
of our shift to an energy transition 
company. Group IT Security is closely 
monitoring the external threat landscape 
for cyber-attack use cases, varying in 
sophistication from the use of AI to create 
more realistic or error free phishing emails 
to deepfake technologies and polymorphic 
malware that is created using AI to better 
evade defences. Equally, our core security 
vendors are all moving to incorporate AI 
into their product offerings in order to 
compete and counterattack vectors.
2. Sustainability risks
JM is committed to complying with 
regulations concerning sustainability. 
As part of this we are putting in place 
mitigation strategies to help deal with our 
compliance and reporting procedures. Not 
reporting accordingly against sustainability 
disclosure rules could result in fines or loss 
of reputation. 
The mitigation strategies include constant 
horizon scanning, reinforcing the message 
that ESG disclosure needs to be a priority, 
education of colleagues about the issues 
and methodologies for disclosure, 
underpinned by putting in place 
a robust reporting system overseen 
by our sustainability team.

Going concern and viability
Going concern
In adopting the going concern basis for preparing 
the accounts, the directors have considered the 
business activities as set out in the Strategic 
report and Financial review, pages 1 to 74, 
as well as the group’s principal risks and 
uncertainties, pages 62 to 70. As part of this 
assessment, we have considered a base case and 
severe but plausible trading scenario. Both 
scenarios showed sufficient headroom under our 
committed facilities and financial covenants. 
As a final review, given the climate of greater 
political and economic uncertainty, we have also 
undertaken a reverse stress test to identify what 
additional or alternative scenarios and 
circumstances would threaten our financial 
covenants or headroom. This shows that we have 
headroom against either a further decline in 
profitability of approximately 50% in the financial 
year to March 2025, well beyond the severe-but-
plausible scenario, or a significant increase in 
borrowings (net debt would need to more than 
double in the financial year to March 2025), 
or a significant increase in interest charges 
(these would need to rise more than 70%). 
In this unlikely scenario, we still have other 
mitigating actions available including retaining 
the full expected proceeds from divestment of 
Medical Device Components, reducing capital 
expenditure, renegotiating payment terms or 
reducing our dividend. The directors therefore 
believe that the group has adequate resources to 
fund its operations for the period of 12 months 
following the date of this report, making it 
appropriate to prepare the accounts on a going 
concern basis. Further details on going concern, 
viability and facilities can be found in note 1 on 
page 149 of the accounts.
Viability
We have assessed how viable we are as a business 
over a three-year period, in line with our 
planning horizon as this represents a timeframe 
over which the directors believe they can 
reasonably forecast the group’s performance. 
During the year, the board carried out a robust 
assessment of the principal and emerging risks 
affecting our business, particularly those that 
could threaten our business model. The risks,  
and the actions taken to mitigate them, are 
described in the Risk report on pages 62 to 70. 
We assess our prospects through our annual 
strategic and business planning process. 
This process includes a review of assumptions 
made including market, vehicle and production 
outlooks, customer demand, underlying growth, 
cost assumptions, metal prices, key risks and 
opportunities as well as an appraisal of our 
strategy and significant capital investment 
decisions. The Chief Executive Officer and Chief 
Financial Officer lead these reviews, along with 
the Chief Executives of each business.
The board also reviews the strategy for each 
business throughout the year, looking at our 
current position and prospects for the coming 
years. This allows us to reaffirm our overall 
strategy and reassess the risks that could 
impact its success.
We do not expect climate change risks to have 
a material near-term effect on our forward-
looking forecasts for going concern or viability. 
See scenarios opposite for more details 
of our analysis.
Analysis through five 
stress scenarios
In making the viability assessment, we have 
analysed each of the principal risks facing the 
group – as described in the Risk report on pages 
62 to 70 – and identified the items within each 
principal risk category that might significantly 
affect cash flow and viability. We have then 
modelled these in five stress scenarios.
Scenario 1 – Geopolitical and 
macroeconomic risks impacting 
JM’s operations
This scenario considers the increased risk 
presented by geopolitical and macroeconomic 
risks, such as a six-month slowdown in our 
operations in China. This builds on the severe but 
plausible trading scenario which considers faster 
electrification and a reduction in end industry 
growth across the group. 
Scenario 2 – Delivering on key 
initiatives (transformation 
programmes and capital projects) 
This scenario considers the failure to execute 
key initiatives and projects effectively. It includes 
the impact of a six month delay to key capital 
projects, and delays to delivery of transformation 
and other cost savings. 
Scenario 3 – Failure in one or more 
of our critical operational assets 
This scenario covers a temporary one-month 
shutdown of a refinery, which leads to higher 
working capital and lower profits, as well as  
a temporary shutdown to key sites due to 
potential external events, such as supply chain  
or cyber issues.
Scenario 4 – Disruption to the 
platinum group metals value chain
This scenario considers the failure to secure metal 
deposits and failure to source sufficient metal 
to manage and satisfy our internal and external 
obligations. We modelled an increase in metal 
prices to highs over the period April 2023 to March 
2024 and reduction of customer metal funding.
Scenario 5 – Other risks
This scenario includes the effect of all our other 
principal risks — outlined in the Risk report on 
pages 62 to 70 — where not already considered in 
the scenarios above. For each risk, we have 
estimated a financial effect, which considers the 
impact and likelihood of the risk. Given the wide 
range of risks we face, we have then applied an 
overall probability weighting of 20% which allows 
us to work out the potential financial impact. 
In evaluating our viability under each of these 
scenarios, we considered our current financing 
arrangements, see page 149, and assumed 
we would not refinance any maturing debt – 
although, in reality, we would expect to refinance 
our debts well ahead of maturity thereby 
increasing headroom. 
At the end of the viability period (March 2027) 
we have £1 billion of debt facilities maturing, 
that will be appropriately replaced well ahead 
of maturity, and we have a strong track record 
of refinancing with no concerns and good 
capacity in the markets where we raise debt.
Conclusion
In all of the scenarios assessed, our stress testing 
shows that, only when all the risks identified 
above are overlaid on the severe but plausible 
trading scenario, there is a breach of headroom 
under our committed facilities in March 2027. 
Given refinancing and other mitigations as noted 
above, the directors have a reasonable 
expectation that the company and group will be 
able to continue operating and meet its liabilities 
as they fall due over the three year period covered 
in the viability review.

Chair’s introduction to governance
Good corporate governance is critical for 
our transformation journey, to be successful 
and sustainable in the long term. This 
report sets out JM’s approach to corporate 
governance and how it contributes to the 
development and delivery of our strategy. 
Strategy
Following the launch of our revised  
strategy in 2022, the board has guided  
and supported management as we continue 
our transformation into an industry-leading 
energy transition company. The board 
receives regular presentations from senior 
management to ensure they are focused  
on delivering sustainable growth and 
returns for our shareholders.
As a board, we take time to understand  
the market opportunities and customer 
demand to ensure our businesses can 
deliver in line with our stakeholders 
expectations. Due to the slower pace in 
market development, we took the decisions 
to reduce our investment and delay the 
start-up of production of our new Hydrogen 
Technologies plant at Royston, UK. The 
board is confident that the green hydrogen 
opportunity remains and we continue to 
monitor the market and challenge 
management, to ensure the business adapts 
to the changing needs of our customers.
Board composition  
and succession 
This year, the board, together with the 
Nomination Committee, continued to 
monitor the board’s composition, skills  
and diversity to ensure we have the right 
structure and skills to support and challenge 
the management team. We were delighted 
to welcome Barbara Jeremiah to the board 
in July 2023. Barbara brings strong 
leadership, deep understanding of metals 
and has extensive experience in North 
American markets. You can read more about 
Barbara’s introduction to JM on page 94. 
I am pleased to confirm that during the year 
the board met and continues to meet the 
2024 target set by the Parker Review with 
regard to ethnic diversity at board level, 
and also the targets set by the FTSE Women 
Leaders Review, following the appointment 
of Barbara Jeremiah.
Culture and engagement
Our values provide the framework for how 
we perform our duties, engage with each 
other in JM, and with our customers and 
stakeholders. The board places great 
emphasis on ensuring JM’s culture aligns 
with our purpose, values and strategy and 
considers multiple sources to monitor and 
assess how our culture is embedded. 
We remain mindful of how our decisions 
impact our various stakeholders and the 
range of matters discussed and debated by 
the board during the year can be found on 
page 74. Listening to our colleagues 
enables us to understand what matters to 
them and the challenges to their day-to-day 
work. Board members met with colleagues 
across JM to hear their experience of  
our transformation journey first hand. 
You can read more about our culture and 
stakeholder engagement on pages 90-91. 
Each year, the performance of the board,  
its committees, and individual directors, is 
reviewed in accordance with the 2018 
Corporate Governance Code (the Code), to 
ensure they are operating effectively and  
to identify development opportunities 
where necessary. This year, an externally 
facilitated effectiveness review took place, 
led by an independent consultant. The 
board was pleased by the results of the 
effectiveness review which concluded  
that it continues to function well. More 
information on our externally facilitated 
board and committee effectiveness review 
can be found on pages 84 and 85.
During the year we also took the 
opportunity to simplify our governance  
by reducing the membership of our 
committees and the frequency of our 
meetings. This enables our discussions  
to be more focused as we continue to 
challenge management on the execution  
of our strategy.
Looking ahead
We continue to monitor the ongoing 
regulatory reforms in relation to  
governance and keep our own governance 
arrangements under regular review. 
As such, the board has begun to consider 
the key changes in the new UK Corporate 
Governance Code 2024 which will apply 
to JM from April 2025, to ensure we are 
well placed to meet these requirements. 
As we continue to focus on our strategic 
transformation, I would like to thank  
all colleagues for their hard work 
and commitment during a year 
of significant change.

Code 2018
During the year under review, we have 
applied all the principles and complied  
with all the provisions of the Code except 
provision 41 – engagement with the 
workforce on alignment of executive pay 
with the wider company pay policy. While 
we inform our employees of global changes 
to pay and benefits, we have not actively 
sought a two-way dialogue over executive 
pay. We benchmark remuneration against 
our peers to ensure we offer competitive 
pay and benefits, so we continue to attract 
and retain the highest-calibre candidates. 
During the year, all employees were able 
to provide feedback on a range of matters, 
including remuneration, as part of our 
annual employee engagement survey. 
Read more in our Remuneration Committee 
report on page 107.
The Code is publicly available on the Financial 
Reporting Council (FRC) website, frc.org.uk
Fair, balanced and 
understandable
In accordance with the Code, the board 
considers that, taken as a whole, the Annual 
Report and Accounts 2024 is fair, balanced 
and understandable, and provides the 
information necessary for shareholders  
to assess Johnson Matthey’s position, 
performance, business model and strategy. 
The Audit Committee assesses the process 
that management uses to support the 
recommendation to the board. 
Read more about our FBU process on 
page 102.
Going concern 
The directors have a reasonable  
expectation that Johnson Matthey Plc has 
adequate resources to continue to fund 
its operations for a period of 12 months 
from the date of approval of the financial 
statements. For this reason, they continue 
to adopt the going concern basis in 
preparing the accounts.
Read more about our going concern 
on page 71.
Viability 
The directors have assessed the viability  
of the company and group over a three-year 
period, taking into account the group’s 
current position and the potential impact 
of the principal risks and emerging risks. 
Based on this assessment, the directors 
confirm they have a reasonable expectation 
that the company and group will be able 
to continue operating and meet its liabilities 
as they fall due over the three-year period 
to 31st March 2027.
Read more about our viability 
on page 71.
Risk assessment of the principal 
risks facing the company and 
annual review of systems of risk 
management and internal control
The board acknowledges its responsibility 
for establishing procedures to manage risk. 
During the year, the board reviewed the 
effectiveness of the company’s risk 
management and internal control systems 
and conducted a robust review of the 
company’s principal risks. These activities 
meet the board’s responsibilities in 
connection with risk management and 
internal control as set out in the Code.

the principal risks facing the Company 
and annual review of systems of risk 
management and internal control on

Our board committees
From January 2024, the membership of our board committees was reduced, to align with the company’s overall approach to simplifying the business. Whilst there had been benefits in 
all non-executive directors being members of all committees, it was felt that a more focused membership would enhance efficiencies to support the delivery of our strategic priorities. 
The number of board and committee meetings held during the financial year are included on page 77. The board keeps the number of meetings under review to ensure that  
non-executive directors have sufficient time to discharge their duties.
 Governance Framework: matthey.com/governance-framework
 Details of GLT members and their relevant experience are on our website: matthey.com/GLT
In May 2024, as we continued to simplify our governance, the board agreed to consolidate the responsibilities of the Ethics Panel, which, among other things, oversaw our Speak Up 
programme, to the Societal Value Committee.

Stakeholder engagement is vital to building 
a sustainable business. The board recognises 
the need to foster positive business 
relationships with suppliers, customers 
and governments.
This section provides more details on how 
the directors have fulfilled their duties. 
The matters we consider differ in relevance 
for each stakeholder, and sometimes 
stakeholders may have conflicting interests. 
We aim to consider the key issues relevant 
to each stakeholder group and our decisions 
will ultimately promote the group’s 
long-term success, and support our vision, 
purpose and strategy. In making decisions, 
we consider the interests of stakeholders 
across the company – not just 
at board level.
Transforming the way we 
operate – JM Global Solutions
Making JM simpler, more agile and more 
cost-effective are key parts of how we 
can ‘Play to Win’ and deliver our strategy. 
To support the delivery of our strategy 
we explored the benefits that a global 
business services hybrid operating model 
could bring to the way we deliver human 
resources, finance and procurement 
services. Following discussion and detailed 
review, the board took the strategic decision 
to implement JM Global Solutions. 
Stakeholder engagement in action
Stakeholder considerations
Suppliers 
Moving our source-to-pay services to JM 
Global Solutions gives us the opportunity 
to simplify and clarify our procurement 
processes and systems.
Our people 
Transforming our culture and the 
way we operate impacts our people. 
Moving a range of activities from our local 
human resources, finance and procurement 
teams to JM Global Solutions means 
reducing the size of our local teams, whilst 
providing the opportunity to simplify our 
processes to support our people in getting 
things done during their JM life cycle, from 
recruitment to retirement. We understand 
the impact that transformation can have. 
To support our people and build 
understanding of this change, we are in 
regular communication with our people, 
we are holding redeployment workshops 
and we have made toolkits and assistance 
programmes available.
Investors 
Through regular updates we are closely 
monitoring the roll-out of JM Global 
Solutions. This allows us to challenge 
management and ensure that we achieve 
the benefits of JM Global Solutions as 
quickly as possible for our investors and 
wider stakeholders, whilst minimising 
disruption to our business.
Outcomes and impact on our 
long-term success 
We believe that this way of operating 
will result in a better experience for our 
suppliers, colleagues and investors. It offers 
an effective solution for process delivery 
and can help create more structure and 
standardisation, less duplication and clearer 
accountabilities, supporting us to become 
simpler, more agile and more cost-effective. 
“To be successful, every business needs to adapt and 
change. We are no exception. JM Global Solutions 
represents a new way of working for everyone. It means 
us doing some things differently in return for doing 
them better.” 
Peter Hill, Group Global Services and Transformation Director

Deepening our relationships
JM’s first global supplier convention 
In November 2023, the Procurement team hosted our first ever global supplier 
convention, bringing together senior representatives from our key suppliers and  
JM business stakeholders. This event, themed ‘Play to Win Together’, provided an 
opportunity to connect our suppliers with our JM strategy. It also allowed us to 
refresh our dialogue to collaborate with transparency and strategic intent, share 
knowledge and insights to anticipate market uncertainty and supply chain risks, 
and unlock future value. 
Stakeholder considerations 
Customers 
Investing in and developing our supplier relationships 
is key to building a robust supplier ecosystem to deliver 
for our customers through more resilient and sustainable 
supply chains. 
Investors 
The delivery of sustainable profitable growth requires a strong 
supplier ecosystem. The board considered that having the right 
business partnerships with our suppliers would positively 
contribute to investors’ long-term returns.
 
Communities  
and society 
We have been evaluating our suppliers through EcoVadis, our 
sustainability rating provider, to better understand their 
performance in human rights and health and safety, as well as 
their journey to net zero. Improving JM’s supplier relationships 
enables us to collaborate to reduce wastefulness, embed 
circularity, adopt sustainable practices, ensure an ethical value 
chain and maintain the highest standards in procurement. 
Suppliers
Our global supplier conference signifies a step change in how 
we work with our key suppliers. It illustrates how much we 
value their commitment to JM. It promotes engagement 
and collaboration to evolve from transactional relationships 
to true business partnerships, in unlocking value and ensuring 
a resilient, ethical supply chain.
Outcomes and impact on our long-term success 
This inaugural convention was such a success that we intend to make it a regular 
occurrence. The collaborative dialogues and ideas generated during this event have 
developed into projects to deliver practical solutions to enhance JM’s responsible 
sourcing, whilst driving profitable revenue growth to support our customers 
in catalysing the net zero transition. 
Delivering on our milestones 
Divestment of Medical Device Components 
Through our strategic review, Medical Device Components (MDC), a business 
producing components for medical device manufacturers globally, with a focus on 
precious metal alloys and nitinol, was identified as non-core to JM’s growth strategy.  
In March 2024 we announced the sale of MDC to Montagu Private Equity.
“This deal supports the delivery of one of JM’s 
strategic milestones, the divestment of Value 
Businesses.” 
Louise Melikian, Chief Strategy and Corporate Development Officer
Stakeholder considerations 
Investors 
To create long-term value for our shareholders through profit 
growth and improved margins, we need to invest in growth. 
The board’s decision to divest MDC supports our strategy 
of playing to win in exciting growth markets where our core 
competencies and technology portfolio can have maximum 
impact. This transaction provides investment for growth for the 
benefit of our investors. As previously announced, and in line 
with our stated capital allocation policy, it is the board’s current 
intention to return to shareholders £250 million of the net sale 
proceeds by way of an on-market share buyback programme, 
subject to completion of the sale.
Our people
Transforming JM into a leading global energy transition 
company requires us to take difficult decisions. The board 
considered the strategic review recommendation to divest MDC 
and whilst it is hard to let go of our colleagues, we have found 
a good fit for MDC to grow and develop its already strong 
and profitable business, led by Montagu Private Equity’s strong 
and committed leadership team.
Outcomes and impact on our long-term success 
This sale is expected to complete by autumn of 2024 and at completion will deliver 
cash consideration of US$700 million (£550 million) to the business. This transaction 
supports the simplification of our business and one of our strategic milestones, 
the divestment of Value Businesses. Delivering in these areas ensures we are positioned 
to create long-term value to support our transformation into a leading global energy 
transition company.

Sustainability Performance Data Book: 
matthey.com/sustainability-databook
Now in its third year, the Societal Value 
Committee has continued to support the 
board by providing challenge and rigour to 
our sustainability strategy. The committee 
received regular updates on performance 
towards achieving our ambitious sustainability 
targets for 2030. These targets build upon our 
inspiring science and innovation to support 
the energy transition that will benefit society. 
The committee has been pleased with the 
progress made to reduce our Scope 1 and 2 
greenhouse gas (GHG) emissions by 44%, in 
part due to the efforts to switch to renewable 
electricity, and by the SBTi’s validation of our 
near-term and long-term ambitions. We also 
discussed the importance of further 
embedding circularity in what we do, as 
exemplified by a new methodology to provide 
100% recycled PGMs to selected customers 
and innovation in recycling. Circularity is one 
of the pillars of our Nature strategy, which we 
reviewed this year. This will ensure that 
climate, circularity and nature are at the 
forefront of our operations and sourcing 
strategy in order to achieve our targets.
In addition, the committee was kept informed 
of how we engage with stakeholders on 
sustainability, both with our colleagues 
(e.g. through the Sustainability Champions 
network or through volunteering) and 
external stakeholders. The committee 
“Sustainability has remained at 
the heart of JM as we undergo 
our transformation.”
But monitoring culture is not enough. 
As board members, we need to see and 
experience this for ourselves and the 
committee has reviewed the mechanisms for 
the board to engage directly with the 
workforce. This mechanism provides a 
two-way dialogue between our workforce and 
the board, so we can understand the topics 
that really matter to our colleagues. 
Our externally-led committee effectiveness 
review for 2024 showed that the committee 
has risen into a substantial forum from its 
inception and continues to operate well. 
The committee will keep the scope of its 
responsibilities under review throughout the 
year, to ensure these remain appropriate and 
support our board objectives.

The committee’s role
Societal value covers a range of economic, 
social and environmental topics. Given the 
central role of sustainability to our overall 
strategy, the committee was established in 
2021 to bring continued focus to this area. 
The committee assists the board in 
overseeing the group sustainability strategy, 
including net zero commitments and 
science-based GHG targets, monitoring 
culture and driving a truly inclusive 
organisation, overseeing the group’s  
ethical conduct, and keeping up to date 
with societal value topics, including 
stakeholder expectations.
Information on the governance of 
sustainability matters beyond the 
committee’s role can be found within our 
TCFD disclosures on page 53.
Committee outcomes 
The outcomes of the committee’s key 
activities during the year included:
•	 Challenged sustainability performance 
data and agreed on adjustments to our 
2030 targets
•	 Agreed and recommended to the 
Remuneration Committee sustainability 
targets for the next three years for 
incorporation into our Performance 
Share Plan
•	 Reviewed Scope 1,2 and 3 GHG footprint 
including the levers to reach our 
reduction targets by 2030
•	 Refreshed our responsible 
sourcing principles
•	 Reviewed our updated roadmap to meet 
our net zero commitment by 2040
•	 Agreed a new nature strategy, reflecting 
our commitment to nature protection

updates, including future sustainability 
reporting requirements and benchmarks
•	 Received updates on ethics and 
compliance matters, including Speak Up 
trends, ethical dilemmas and ethical 
culture heatmaps
•	 Reviewed the Speak Up process and 
agreed this was effective
•	 Agreed to recommend the Modern 
Slavery Statement 2023 to the board 
for approval
•	 Discussed the results of the external 
committee effectiveness review and 
agreed related actions.
Culture
During the year, it was agreed that the 
committee’s responsibilities would expand 
to monitor culture across JM. A high-
performing culture generates and protects 
value, supporting our strategy to achieve 
our purpose of catalysing the net zero 
transition. Our cultural transformation is 
centred on three pillars: people growth, 
customer focus and simplification. 
The committee considers multiple sources 
to assess the strength of culture and 
understand employee sentiment through 
regular reporting and metrics, including:
•	 Feedback from the board’s direct 
interaction with the workforce, through 
engagement forums, site visits and 
interactions with management
•	 Bi-annual reviews of the cultural dashboard
Societal Value Committee report continued
  Governance in action: our cultural dashboard
Our cultural dashboard enables the committee to track progress of our  
cultural transformation.
During the year, the committee agreed the form of a cultural dashboard comprising 
data relating to the key dimensions of the ‘Play to Win’ behaviours. The dashboard acts 
as a check for the committee on the cultural context in which our colleagues work, 
and allows us to identify any areas of misalignment and take appropriate action.

Engagement with the workforce
Engaging with the workforce at all levels 
allows the board to understand the culture, 
issues and challenges across our business. 
During 2022/23, the engagement forums 
led by non-executive directors in key 
countries where we operate were paused, 
to allow for direct engagement between 
management and employees on the 
refreshed strategy and cultural ambition. 
During the year and on behalf of the board, 
the Committee reflected upon the 
workforce engagement methods specified 
by the UK Corporate Governance Code 2018 
and agreed that the global and diverse 
network continued to require a different 
approach. The committee agreed that the 
engagement forums in key countries should 
be re-established but in a simplified form to 
encourage open and honest conversations. 
During the year and up to the date of this 
Annual Report and Accounts, engagement 
forums have been held in the UK, China and 
the US, comprising diverse colleagues from 
different businesses, functions, job types, 
ages and tenures. These face-to-face 
sessions included informal discussions 
between approximately eight colleagues 
and a non-executive director. These centred 
on the understanding of JM’s transformation 
journey, opportunities to improve 
engagement and how enabled colleagues 
feel to deliver in their role. To support 
unconstrained dialogue, it was important 
that local management were not present 
for the forums. The directors shared their 
feedback from the engagement forums 
with the committee and applicable senior 
leaders. The non-executive directors have 
also collectively met with colleagues over 
lunch as part of the board agenda,  
following similar principles to the 
engagement forums.
The committee intends to continue its 
approach to workforce engagement and 
will look to hold engagement sessions in 
other countries during 2024/25. Alongside 
this, the board continues to engage with 
colleagues via site tours, face-to-face 
discussions at meetings and attendance  
at employee events.

Nomination  
Committee report
This year, a key focus for the committee  
has been succession planning, for both the 
board and Group Leadership Team (GLT), 
whilst ensuring the board and its committees 
have the collective skills needed to oversee 
JM’s transformation. Chris Mottershead 
retired from the board in January 2024, 
having been a director for nine years. 
The committee monitors the tenure of 
non-executive directors closely to ensure 
effective succession planning and we 
strengthened the board’s composition with 
the appointment of Barbara Jeremiah as an 
independent Non-Executive Director in 
July 2023. You can read more about 
Barbara’s induction to JM on page 94.
The committee spent time on executive 
succession to ensure we have the right 
leaders to deliver our transformation and  
to support the long-term success of the 
company, and we oversaw a number of 
changes to the GLT.
The committee recognises the importance 
of diversity in driving meaningful change 
across JM. This includes the board, and the 
committee was pleased to increase its board 
diversity targets in line with the FCA’s 
Diversity Listing Rules.
Simplification is a key part of our 
transformation and there are opportunities 
to be realised in all areas of the organisation. 
You can read more about how we simplified 
our committees on page 93.
Our externally-led board and committee 
effectiveness review for 2023/24 (see pages 
82 and 83) confirmed that our discussions 
are open and honest, with an atmosphere 
of trust. During 2024/25, the committee 
intends to focus on medium to longer term 
succession planning, considering the skills 
needed to support our strategy.

Board composition
The committee regularly reviews the 
composition of the board and its 
committees to ensure there is an 
appropriate balance of skills to support the 
company’s strategy. This is facilitated via an 
assessment of the board’s collective skillset 
by asking each non-executive director to 
identify their strengths, scoring their level of 
expertise on a scale of one to five. The table 
on page 77 shows the skills held by our non-
executive directors that are most relevant to 
their role at Johnson Matthey. This year’s 
externally-led board and committee 
effectiveness review, as detailed on pages 
84-85, included an appraisal of each 
director, their contributions and any areas 
for further development. These individual 
reports were shared with the Chair to 
support a discussion on any gaps that can 
be addressed through future appointments 
or additional training.
The committee is satisfied that each 
director continues to effectively contribute 
to the board and fulfil their duty to promote 
the success of the company. The board and 
committees include a strong mix of 
experienced individuals who provide 
constructive challenge to all discussions.  
All directors have demonstrated a strong 
commitment to their roles and careful 
consideration is given to external 
appointments, to ensure sufficient time  
can be dedicated to their roles on our  
board and committees.

Board composition changes 
during the year
Governance in action: 
simplifying our 
governance
During the year the committee 
considered the composition of  
the board committees. Whilst there 
have been benefits to having all 
non-executive directors as members 
of all committees, it was felt that 
there were opportunities to simplify 
this. The committee considered the 
skills, experience, knowledge and 
diversity when recommending 
committee membership to the board. 
The board approved the proposal, 
which took effect from 2nd January 
2024. The composition of each 
committee as at 31st March and the 
date of this report is set out on 
page 81.
To create further efficiencies, it was 
also agreed to reduce the number of 
board and committee meetings, with 
more committee meetings being held 
virtually and separated from the 
board meetings. This gives the 
committee chairs increased flexibility 
in terms of time and how they 
manage the agendas.

Succession planning 
Board
In January 2024, having achieved a 
nine-year tenure, Chris Mottershead 
stepped down from the board. Ahead of his 
retirement, the committee spent time 
discussing the skills and expertise of the 
board and recommended that a further 
non-executive director be appointed to the 
board as Senior Independent Director. 
The committee sought an individual with 
experience of strong leadership and 
delivering transformation programmes and 
an understanding of the US commercial 
market. Egon Zehnder, a third-party search 
and recruitment specialist, assisted with the 
search. Following evaluation of the final 
short list of candidates, the committee 
recommended Barbara Jeremiah’s 
appointment. It was felt that Barbara’s 
understanding of metals, along with her 
investor experience, would enhance the 
board’s deliberations. Details of Barbara’s 
induction are set out on this page.
GLT
The committee also oversees succession 
planning for senior leadership roles and 
talent development to build capability for 
the future. The committee reviews the 
internal pipeline of candidates for 
immediate and medium to longer-term 
movement to leadership roles. This is 
routinely challenged to ensure the 
committee understands the breadth  
of potential and to balance internal 
succession planning with the need for 
external perspectives. 
During the year, the committee oversaw  
the appointments of Simon Price as General 
Counsel and Company Secretary, Liz Rowsell 
as Chief Technology Officer, Louise Melikian 
as Chief Strategy and Corporate Development 
Officer and Peter Hill as Group Global 
Services and Transformation Director. 
Details of gender and ethnic representation 
as prescribed by Listing Rule 9.8.6 are  
set out in the tables on page 95. The board 
and GLT members confirmed their gender 
and ethnicity for the purpose of collecting 
these data. 
Board Diversity Policy:  
matthey.com/board-diversity
The board also supports the terms of the 
Enhanced Voluntary Code of Conduct for 
executive search firms. All our appointed 
executive search firms are required to 
secure a diverse longlist of candidates, 
including Black, Asian and minority 
ethnic talent. 
The committee also oversaw the 
appointment of Maurits van Tol as Chief 
Executive, Catalyst Technologies, who 
previously held the role of Chief Technology 
Officer, and the increase in responsibilities 
for Mark Wilson, Chief Executive, Hydrogen 
Technologies, to respect of group-wide EHS 
and engineering matters.
Turning to the year ahead, the committee 
intends to focus on board succession to 
ensure an orderly and diverse succession 
plan is in place for key roles.
During the year, Egon Zehnder provided 
senior-level recruitment services, including 
assessment and people development 
services. Egon Zehnder has no other 
connection with the company or any 
other directors.
Diversity and inclusion
The committee continues to drive the 
diversity agenda across JM. A diverse and 
inclusive organisation is fundamental to  
our vision, and our Board Diversity Policy 
ensures that the tone is set from the top. 
Following our commitment last year to 
meet the FCA’s Diversity Listing Rules 
target, and the appointment of Barbara 
Jeremiah, the targets were successfully met.
In April 2024, the committee reviewed  
our Board Diversity Policy and refreshed  
its objectives to reflect the requirements of 
the FCA’s Diversity Listing Rules, FTSE 
Women Leaders and Parker Reviews and 
to maintain:
•	 40% of women on the board
•	 at least one woman in the chair or senior 
independent director role 
•	 one director from an ethnic minority group.
Our Board Diversity Policy is applied 
consistently across all board committees.
Beyond the board, we aspire to have gender 
balance across all levels of the group. One of 
our key milestones is to achieve greater 
than 40% of female representation across 
professional management by 2030 and we 
are on track to achieve this. While gender 
diversity has improved we want to 
accelerate the pace of change. 
Further details on how we are improving 
diversity across the group, the gender 
balance of senior management and our 
Diversity, Equity, Inclusion and Belonging 
Policy are set out on page 47.

The role of the committee
The committee continues to support the 
business in achieving its transformation 
strategic objectives (see pages 14 to 15). 
During the year, the committee supported 
the board on a number of governance 
matters relating to financial reporting and 
internal controls. 
The committee’s principal responsibilities are: 
•	 To monitor the integrity of the reported 
financial information, reviewing 
significant financial considerations and 
judgements.
•	 To review the group’s internal control and 
risk management systems and 
monitoring the effectiveness of the group 
assurance function.
•	 To oversee the relationship with the 
external auditor including monitoring 
their independence and objectivity, 
reviewing and approving external audit 
fees, recommending reappointment or 
not, and ensuring a high-quality, effective 
audit, based on a sound plan.

“The Audit Committee plays 
a vital role in identifying 
risks and monitoring the 
controls in place, to help 
the group to achieve its 
transformation strategic 
objectives.”
During the year, the committee has  
focused on identifying risks and monitoring 
the controls in place to support JM’s 
transformation strategy. This report  
covers the committee’s work in relation  
to financial reporting, internal financial 
controls, internal control and risk 
management systems, and the  
relationship with our external auditor. 
The committee met three times during the 
year, with members of senior management 
present as and when appropriate. The 
committee meets with the external auditor 
and the Director of Assurance and Risk 
separately during the year without 
management present. In addition, the 
committee chair holds regular private 
sessions with the Chief Financial Officer, 
senior members of the finance team, the 
Director of Assurance and Risk, and the 
external auditor, to ensure that open and 
informal lines of communication exist 
should they wish to raise any concerns 
outside formal meetings. In November 
2023, the committee approved an annual

In addition to its regular activities the 
committee focused on a number of key 
areas this year:
•	 Oversight of the group’s integrated 
assurance project, to consolidate and 
map assurance activities, with internal 
audit aligning with the JMGS programme 
to provide assurance over the new ways 
of working.
•	 Monitored the ongoing transformation of 
group finance.
•	 Approved the level of assurance over 
sustainability-related disclosures in the 
Annual Report and Accounts.
•	 Reviewed JM’s cyber readiness and 
challenged management’s identification 
and remediation of specific cyber 
control gaps.
•	 Challenged management on lessons 
learnt from previous strategic changes. 
•	 Reviewed and responded to upcoming 
regulatory changes.
During the year, the committee continued to 
play a key role in assisting the board in its 
oversight responsibility and monitoring the 
integrity of the financial information. This has 
included challenging management on the 
significant accounting judgements made in 
the financial reporting, as well as reviewing 
the analysis behind our going concern and 
viability statements and considering the 
processes that underpin the preparation  
of the Annual Report and Accounts.
The committee received regular updates at 
each meeting from the Director of 
Assurance and Risk, covering the control 
and risk management framework and 
internal audit reviews. The committee 
continued to oversee the programme 
assurance activities, receiving regular 
updates on the progress of key 
programmes. See Governance in action on 
page 97 for more information.

outcomes during 2024 on pages 98-99
Our response to regulatory 
changes
We continue to track developments with 
the UK Government’s corporate governance 
reforms and consider management’s plans 
to respond to the evolving requirements, in 
readiness to adapt to the changes in 
forthcoming years.
In May 2023 the Financial Reporting 
Council (FRC) published a Minimum 
Standard for Audit Committees (the 
Minimum Standard) in relation to external 
audit. The committee reviewed the four 
main areas of focus of the Minimum 
Standard, in conjunction with the current 
UK Corporate Governance Code (2018 
Code) and the FRC Guidance on Audit 
Committees, and determined that the 
Terms of Reference needed to be updated 
to refer to the Minimum Standard.
The committee is reviewing the implications 
of the FRC’s recently published 2024 UK 
Corporate Governance Code (2024 Code) 
and identifying any actions JM needs to take 
to ensure compliance and enhance the 
internal control frameworks. A key 
substantive change in the 2024 Code is the 
requirement for the board to include a 
declaration in the Annual Report and 
Accounts on how it has carried out the 
review of the effectiveness of the company’s 
risk management and internal controls 
framework and their conclusions. This new 
requirement for a board declaration in the 
Annual Report and Accounts will come into 
effect for JM in the financial year starting 
1st April 2026. 
In August 2023, the UK Government 
published information on its framework for 
creating UK Sustainability Disclosure 
Standards (UK SDS) based on the ISSB 
Standards which set out corporate 
disclosures on the sustainability-related risks 
and opportunities that companies face. 
The standards will form the basis of any 
future requirements in UK legislation or 
regulation for companies to report on risks 
and opportunities relating to sustainability 
matters, including those arising from 
climate change. Although the ISSB 
Standards will not replace the TCFD 
disclosure framework immediately, the ISSB 
Standards will be considered now to build 
them into future plans. 
Audit Committee report continued
Successful transformational change is an 
integral part of our business strategy. JM 
has embarked on a programme of work 
that will take several years to complete, 
and to support this, our internal audit 
team has adapted its engagement with 
these programmes, seeking innovative 
ways to proactively support programme 
delivery by providing timely insights.
A work stream undertaken by internal 
audit, that was recognised by the board 
and senior management as being of 
significant benefit, was a review of 
previous major change programmes 
delivered by JM, specifically Unify, 
a programme delivering global, 
standardised Enterprise Resource 
Planning (ERP) processes, data and 
systems across JM. Internal audit 
identified themed lessons learnt,  
taking into consideration other  
key transformation programmes.  
These lessons learnt were widely shared, 
from board and GLT level, down through 
the organisation to those running 
current programmes.
An example where we demonstrated 
lessons learnt from Unify was the JM 
Global Solutions (JMGS) programme 
where engagement on risk assurance has 
brought transparency and improvement 
to the governance rigours employed by 
the programme teams. Another example 
was the engagement on the capital 
projects assurance, on which GAR 
presented a summary of lessons to be 
learnt from the delivery of five previous 
projects. The findings from this work, 
together with work conducted by an 
independent specialist third-party 
assurance provider, enable the project 
teams to drive tangible improvements  
in the processes and controls of 
current projects. 
Governance in action:  
lessons learnt and missed opportunities
The aligned assurance approach contained 
within the Group Assurance and Risk (GAR) 
plan will help move JM towards the 
assessment of the effectiveness of risk 
management and internal controls. 
Although references to the Audit & 
Assurance Policy (AAP) have not been 
included in the 2024 Code, the committee 
will continue to review and update the  
internal AAP, because it is important to 
document how the board obtains assurance 
over JM’s risks and external reporting.

Committee outcomes 
Financial reporting
•	 At the conclusion of the Annual Report 
and Accounts 2023, the committee 
reviewed the process, including 
challenges and what went well, and 
agreed actions to improve the process for 
the following year.
•	 Reviewed the group’s financial 
statements and results announcements, 
with consideration given to the 
appropriateness of accounting policies 
and critical accounting judgements. 
Recommendations were made to the 
board supporting the half and full-year 
accounts and financial statements.
•	 Reviewed credit controls and risks in the 
context of continuous challenging 
market conditions.
•	 Reviewed management’s consideration of 
the various FRC thematic reviews and 
guidance for financial reporting.
•	 Reviewed our operating metal framework, 
developed by management in response to 
a request from the Committee.
Narrative reporting
•	 Considered the viability and going 
concern statements and their underlying 
assumptions, evaluating going concern 
over an 13-month period, which included 
a review of financial plans and 
assumptions, access to financing and the 
challenging economic environment and 
the adaptability of financial plans. The 
committee also considered the 
appropriateness of a three-year viability 
assessment period after modelling the 
impact of certain scenarios arising from 
the group’s principal risks. 
•	 Reviewed and approved the enhancement 
of the process of verification of the 
contents of material statements contained 
in the non-financial and narrative 
reporting within the Annual Report and 
Accounts 2024, and approved the scope 
of, and provider of, external assurance 
over sustainability data.
Internal control and risk 
management
•	 Oversight of significant work performed 
on business controls across several key 
processes, and independent testing of 
those controls, providing more 
confidence on improvements in the 
control environments and a focus on 
remediation efforts. The committee has 
oversight of the changing control 
environment resulting from the 
transformation. In particular the move to 
JMGS is a critical change for JM and as a 
new way of working is pivotal for our 
controls culture. 
•	 Challenged management to resolve issues 
relating to internal controls and risk 
management systems. Following a site 
extended audit performed by internal 
audit, the committee provided feedback 
to the Clean Air business on its risk 
control environment and the 
improvements made.
•	 Technology assurance is an area where 
the committee has challenged 
management to identify specific cyber 
control gaps, where remediation would 
provide the greatest level of risk 
reduction, and improve controls (in 
particular Operational Technology, our 
technology infrastructure that drives 
manufacturing equipment).
•	 Reviewed and approved changes related 
to controls and liquidity in the group’s 
precious metals policy.
•	 Considered and agreed with 
management’s determination that there 
were no significant control weaknesses or 
lack of adherence to policies and 
procedures identified. 
•	 The committee met with the Group’s new 
head of tax and reviewed tax risks and 
mitigation plans around both direct and 
indirect taxes.
External audit
•	 After due challenge and discussion,  
the committee agreed the scope  
of the external audit process prior to 
commencement of the 2024 audit. 
The committee appraised the 
effectiveness and performance, 
independence and objectivity of PwC, 
our external auditor, approved the 
external audit fees and terms of 
engagement, reviewed and approved 
non-audit services and kept under  
review the Non-Audit Services Policy.
•	 Determined that a good quality, 
comprehensive audit was completed for 
FY2023/24, following a review of PwC’s 
regular reports to the committee, and 
feedback from PwC’s independent quality 
review partner. As a result, the 
committee recommended PwC’s 
re-appointment.
•	 The committee approved the proposal 
from management for six subsidiaries 
within the group to apply for an audit 
exemption by way of a parent guarantee 
under the Companies Act 2006. This 
decision would result in a cost saving  
for the group, and the removal of the 
external audit process and associated 
internal administration. The committee 
reviewed the additional controls required 
to be established to maintain high-quality 
accounting standards.
Audit Committee report continued
Given the importance of sustainability to 
JM, whilst the 2024 Code does not include 
wider responsibilities and considerations for 
the board and audit committee in relation 
to sustainability objectives and other 
sustainability matters, the committee  
will continue to review and assess the 
sustainability goals and targets 
recommended by the Societal Value 
Committee to ensure they remain 
measurable and assurable.
The Institute of Internal Auditors’ (IIA) 
mandatory 2024 Global Internal Audit 
Standards were published in January 2024, 
and will apply to JM from April 2025. 
During 2024/25 the committee will review 
the standards as a basis for evaluating and 
elevating the quality of our internal 
audit function.
Committee effectiveness
The externally facilitated board and 
committee effectiveness review for 2024 
(see page 84) concluded that the 
committee continues to operate effectively, 
while recognising certain areas may benefit 
from further development. These include 
managing the ever-growing agenda to 
ensure appropriate focus on the most 
important topics, continued focus on the 
group’s evolving internal control systems, in 
particular the maturing of assurance plans 
over non-financial data, and monitoring the 
evolution of the internal audit function. 
These will be considered in the forthcoming 
financial year.

Financial reporting
Significant issues considered by the committee in relation to the 
group’s and company’s accounts
It is a fundamental part of the committee’s role that we act independently from 
management to ensure that the interests of shareholders are properly protected in relation 
to financial reporting. When the accounts are being prepared, there are areas where 
management exercises a particular judgement or degree of estimation. The committee 
assesses whether the judgements and estimates made by management are reasonable and 
appropriate. In the process of applying the group’s accounting policies, management also 
makes judgements and estimates that have a significant effect on the amounts recognised in 
the financial statements. The group’s key accounting judgements discussed and challenged 
by the committee are set out below.
Significant current year considerations in 
relation to the accounts
Work undertaken / outcome
Impairment of goodwill, other intangibles 
and other assets
Key judgements are made in determining 
the appropriate level of cash generating unit 
(CGU) for the group’s impairment analysis. 
Key estimates are made in relation to the 
assumptions used in calculating discounted 
cash flow projections to value the CGUs 
containing goodwill, to value other 
intangible assets not yet being amortised, 
and to value other assets when there are 
indications that they may be impaired. The 
key assumptions are management’s 
estimates of budgets and plans for how the 
relevant businesses will develop or how the 
relevant assets will be used in the future, as 
well as discount rates and long-term average 
growth rates for each CGU.
We reviewed a report from management 
explaining the methodology used, 
assumptions made, and significant 
changes from those used in prior years. 
In light of the current volatile 
macroeconomic environment, including 
high interest rates and energy costs, 
management considered the impact 
within underlying forecasts and 
discount rates. 
We challenged management on the 
rationale behind the key assumptions and 
sensitivities such as discount rates and 
growth rates in the goodwill value in use 
calculations, especially within Clean Air 
and Catalyst Technologies, to ensure we 
were satisfied on their reasonableness.
The impairment reviews were an area of 
focus for PwC who reported their findings 
to us. 
We concluded that management’s key 
assumptions and disclosures are 
reasonable and appropriate.
Internal audit
•	 Following regular reports from the 
Director of Assurance and Risk, the 
committee determined that risk 
management and internal controls 
effectively meet the group’s needs and 
manage risk exposure.
•	 Monitored progress against the 2023/24 
GAR plan, which focused on execution 
against its four pillars and agreed the 
2024/25 plan.
•	 Assessed the results of a programme 
review carried out by GAR and group IT, 
with ‘lessons learnt’ recognised and to be 
reflected in the design and 
implementation of current and future 
transformation programmes, to ensure 
they are delivered in an optimal way. See 
Governance in action: JMGS on page 82 
for more information.
•	 Oversight of the internal audit team 
delivering a comprehensive set of 
assurance across four pillars, being 
operating site reviews, key areas of 
business and financial risk including 
cyber, IT enabled changes and business 
transformation. The function has also 
progressed the aligned assurance 
mapping and has been engaged with 
JMGS to provide assurance over new 
ways of working. 
Sustainability
•	 Reviewed the sustainability assurance 
framework and concluded that it 
continued to deliver against what was 
agreed by the committee in 2022. The 
framework will continue to apply and 
evolve in line with upcoming regulations, 
with updates provided to the committee 
and an annual review included in the 
committee’s annual planner. 
Audit Committee report continued
•	 In understanding the need for 
transparency and accuracy of our 
sustainability data, in conjunction with 
the Societal Value Committee, the 
committee agreed to appoint an 
independent third party, which, in 
conjunction with internal audit, provided 
limited assurance to ISAE3000 for 
selected sustainability data in our Annual 
Report and Accounts 2023. The 
committee reviewed the interim and final 
assurance certificates which concluded 
that the 2022/23 selected information 
presented in the Annual Report and 
Accounts 2023 was fairly stated, in all 
material respects, in accordance with the 
reporting criteria.
•	 Ensured the Task Force on Climate-
related Financial Disclosures (TCFD) 
recommendations were incorporated into 
the Annual Report and Accounts 2023 as 
appropriate, following an assessment by 
management of how the considerations 
of TCFD impacted the financial accounts. 
Those areas within the accounts  
which are likely to be impacted by 
climate change disclosures are 
continuously monitored.
Governance and regulatory 
updates
•	 Remained well-informed of key regulatory 
developments relating to audit committees, 
such as the FRC Minimum Standard for 
audit committees, the Spring Report, 
Restoring trust in audit and corporate 
governance, and the 2024 Code.
•	 Reviewed and approved JM’s submission 
to the FRC in response to its UK Corporate 
Governance Code Consultation published 
in May 2023, following a review of the 
consultation paper and the associated 
questions led by a cross-functional 
working group.

Significant current year considerations in 
relation to the accounts
Work undertaken / outcome
Major impairment, restructuring activities 
and transformation costs
Key judgements in relation to impairment 
testing relate primarily to estimates in 
assessing recoverable value.
Key judgements in relation to restructuring 
provisions related to estimates of future cost 
and the disclosures relating to 
transformation costs.
We reviewed a report from management 
outlining the work carried out to assess 
the carrying value of the Hydrogen 
Technologies CGU following an 
impairment indicator that the recent 
slowdown in growth within the hydrogen 
and fuel cell market required a formal 
review for possible impairment. The 
assessment considered the net present 
value of the post-tax cash flows expected 
to be generated by the CGU. The 
approach involved an estimation of 
future cash flows and a selection of 
appropriate key assumptions including 
growth and discount rates. Management 
concluded that no impairment was 
required to be recognised.
We challenged management on the 
rationale behind the key assumptions 
and the methodology applied to assess 
the carrying value of the CGU. We 
concluded that management’s key 
assumptions and disclosures are 
reasonable and appropriate.
We received a report from management 
explaining the basis of recognition  
and estimate for impairments and 
restructuring/transformation costs. 
The report also detailed how 
transformation related costs reconciled 
back to previously announced 
transformation programmes. 
We challenged the rationale behind  
the presentation of the costs as non-
underlying, with particular focus  
on areas that required judgement 
around recognition.
We concluded that management has 
appropriately accounted for, and 
disclosed the impacts from major 
impairment and restructuring activities 
(see note 6 in the annual report).
Significant current year considerations in 
relation to the accounts
Work undertaken / outcome
Loss on disposal of businesses and 
businesses classified as “held for sale”.
Key judgements in relation to assessing the 
fair value less costs to sell of businesses 
classified as “held for sale”.
We reviewed and discussed the 
accounting for the following disposals:
On 15th June 2023, the group completed 
the sale of Johnson Matthey Catalysts LLC 
for a cash consideration of £11 million.
On 29th September 2023, the group 
completed the sale of its Diagnostic 
Services business for an enterprise value 
of £55 million (£47 million on a debt 
free basis after working capital 
adjustments).
On 31st December 2023, the group 
completed the sale of the trade and 
assets (excluding cash) of its Battery 
Materials Germany business for a cash 
consideration of £1 million.
The group recorded £9 million of disposal 
related costs. This is comprised of 
£7 million for the disposals of Medical 
Device Components (£5 million) and 
Battery Systems (£2 million) which were 
signed during the year, and £2 million in 
relation to disposals in prior years. 
We concluded that management’s key 
assumptions and disclosures on the loss 
on disposal of businesses above were 
reasonable and appropriate. 
We also considered the assessment in 
arriving at the fair value less costs to sell 
of the Battery Systems business and 
agreed management’s classification as 
“held for sale” was appropriate and that a 
£45 million impairment was required. 
We agree with management’s assessment 
to also classify Medical Device Components 
and Battery Materials Poland as “held 
for sale”.

Significant current year considerations in 
relation to the accounts
Work undertaken / outcome
Refining process and stocktakes
When agreeing commercial terms with 
customers and establishing process loss 
provisions, key estimates are made of the 
amount of precious metal that may be  
lost during the refining and fabrication 
processes. Refining stocktakes involve  
key estimates regarding the volumes of 
precious metal-bearing material in the 
refining system and the subsequent 
sampling and assaying to assess the  
precious metal content.
We received a report from management 
summarising the results of the refinery 
stocktakes in the US. The report was 
reviewed to ensure that the results  
were in line with expectations and 
historic trends.
The refining process and stocktakes were 
an area of focus for PwC who reported 
their findings to us.
We concluded that management’s 
accounting for refining stocktake gains 
and losses was in accordance with the 
agreed methodology.
Post-employment benefits
Key estimates are made in relation to the 
assumptions used to value post-employment 
benefit obligations, including the discount 
rate and inflation.
The key assumptions are based on 
recommendations from independent 
qualified actuaries.
We received a report from management 
summarising the key assumptions used 
to value the liabilities of the main 
post-employment benefit plans. The 
assumptions were compared with those 
made by other companies, and PwC’s 
assessment of the reasonableness of the 
assumptions was considered.
We concluded that the assumptions used, 
and accounting treatment, are 
appropriate for the group’s post-
employment benefit plans.
Tax provisions
Key estimates are made in determining  
the tax charge in the accounts where the 
precise impact of tax laws and regulations 
is unclear.
We received a report from management 
explaining the issues in dispute, or at risk 
of this, with tax authorities across the 
business, the calculation of tax provisions 
and relevant disclosures. We also 
considered the sensitivities around the 
provisions and debated the circumstances 
in arriving at the key provisions.
We concluded that management’s key 
assumptions and disclosures are 
reasonable and appropriate.
Significant current year considerations in 
relation to the accounts
Work undertaken / outcome
Climate change
Key estimates are made in relation to 
climate change and the impact on the going 
concern period and viability of the period 
over the next three years. Additionally, the 
potential impact of climate on the financial 
statements including forecasts of cash flows 
used in impairment assessments, 
recoverability of deferred tax assets and 
expected lives of fixed assets and their 
exposure to the physical risk posed by 
climate change.
Management has considered the impact 
of climate change in their goodwill 
impairment calculations and going 
concern/viability forecasts.
We concluded that management’s key 
assumptions and disclosures are 
reasonable and appropriate.
We also received a report outlining how 
TCFD considerations are factored into the 
financial statements. 
Provisions and contingent liabilities 
(judgement)
Key estimates are made in determining 
provisions in the accounts for disputes  
and claims which arise from time to  
time in the ordinary course of business. 
Key judgements are made in determining 
appropriate disclosures in respect of 
contingent liabilities.
We received a report from management 
providing information in respect of 
significant disputes and claims, including 
the accounting and disclosure 
implications, which we discussed and 
challenged. Claims, uncertainties and 
other provisions was an area of focus for 
PwC who reported their findings to us. 
We concurred with management’s 
conclusions regarding provisions and 
contingent liabilities and consider the 
disclosures to be appropriate.

can meet liabilities over at least three years, 
which remains the most appropriate time 
span. Further details on our going concern 
and viability statement, and the scenarios 
considered, are on page 71.
Fair, balanced and 
understandable
We review and assess management’s 
process to support the board, so it can give 
its assurance that the Annual Report and 
Accounts, taken as a whole, is fair, balanced 
and understandable (FBU) and provides the 
information necessary for shareholders to 
assess JM’s position and performance, 
business model and strategy.
For the Annual Report and Accounts 2024, 
management selected three individuals 
from across the group, who were not 
involved in the drafting, but were all 
familiar with our strategy and business 
model, to form an FBU panel and carry out 
a detailed review, with the support of GAR 
carrying out checks and balances. The FBU 
panel, PwC and Annual Report project team 
determined whether key messages aligned 
with the group’s position, performance and 
strategy, and whether the narrative sections 
and financial statements were consistent. 
The FBU panel presented a report to the 
board, highlighting the key themes from 
the review and discussion points. The 
Disclosure Committee reviewed the 
verification process dealing with the report’s 
factual content to further support the 
board’s review. 
Risk management and 
internal control
As delegated by the board, the committee is 
responsible for reviewing the adequacy and 
effectiveness of internal financial controls, 
and internal control and risk management 
systems. These controls are a critical 
component of our governance and 
assurance framework, and they detail the 
minimum controls we need to keep our 
people safe, ensure compliance with our 
standards and regulations, protect our 
physical and intellectual assets, and facilitate 
the accuracy and completeness of financial 
reporting. During the year, the committee 
assessed the effectiveness of these controls, 
considered the key identified control gaps, 
and assessed how management planned to 
address the findings.
The Director of Assurance and Risk 
independently assures that our risk 
management and internal control processes 
operate effectively. Working closely with 
leadership and management, she provides 
regular oversight of risk matters that affect 
our business, makes recommendations to 
address key issues, and ensures that any 
mitigating actions are properly tracked, 
challenged and reported. 
The group’s internal controls over financial 
reporting include policies and procedures 
designed to ensure the accuracy of our 
financial statements. JM’s control self-
assessment and business filing assurance 
processes provide management with a view 
of the operation of these controls. The 
results are presented to the committee as 
part of its assessment of the year-end 
control environment. 
The committee is satisfied that the group’s 
internal financial controls operated 
effectively throughout the year and up to 
the date of approval of this report. However, 
these controls do not provide absolute 
assurance against material misstatement or 
loss and are assessed based on materiality 
and level of activities within the business.
Operation of controls 
and assurance
There is an ongoing comprehensive 
improvement programme across JM’s 
financial and operational controls, including 
control self-assessment, which has led to 
positive development in our internal controls 
over financial reporting. During the year, we 
reviewed the controls strategy, focusing on 
several cultural and operational factors to 
ensure JM’s readiness for the enhanced 
reporting on the operating effectiveness of 
controls from 2025/26. A new second level 
line of testing of internal controls was 
introduced during the year to provide 
management with independent assurance 
over the effectiveness of the control self-
assessment process.
Group assurance and risk
The Director of Assurance and Risk provides 
regular reports on internal audit reviews, 
including key findings, actions needed and 
progress on their implementation. We 
continually review the effectiveness of the 
Group Assurance and Risk (GAR) function, 
using inputs including audit reports, 
management’s response to audit actions 
and discussions over risk exposures. We look 
at whether the function has adequate 
standing across the group, is free from 
management influence or other 
restrictions, and is sufficiently resourced.
Integrated or aligned assurance allows us 
the opportunity to have an holistic 
approach to risk management, by 
interacting and working closely with all 
teams responsible for first, second and third 
lines of defence. This co-ordination helps 
set the right risk culture and allows further 
assurance that risks are being appropriately 
identified and controlled across the 
organisation and that appropriate 
mitigation strategies are being put in place.
GAR annual plan
We review the GAR annual plan to ensure 
that it reflects challenges and changes to 
our business. We are confident that it 
provides the appropriate level of assurance 
over the group’s key risks.
When we reviewed the 2024/25 plan, we 
specifically considered whether it continued 
to provide the level of assurance over JM’s 
principal and operational risks, and 
continues to contribute to the improvement 
in our overall controls culture and maturity 
of the second line of defence. 
The GAR annual plan is formed on a 
risk-based audit universe covering areas 
across financial and operational functions 
including IT and transformation activities at 
group and business levels. We consider a 
wide range of risks that fall into those areas, 
including level of change and 
transformation in the group and 
organisational culture. Close collaboration 
with the business ensures it adds value to 
management with pragmatic and 
manageable action plans. The plan also 
allows greater flexibility to ensure that the 
GAR team has capacity to deal with 
unexpected events.
We believe our 2024/25 assurance plans are 
adequate for JM’s size and nature. It is our 
opinion they will continue to provide the 
group with necessary focus on maturing 
controls culture across business and IT 
processes. The quality and standing of the 
GAR function is appropriate to provide 
necessary challenge and support to the 
transforming organisation.

Risk management
We work with the board to review and 
refine the risk assurance processes, 
including the integrated assurance 
framework and control self-assessment. 
We concentrate on reviewing the mitigating 
controls and the levels of assurance, 
while the board is directly responsible for 
managing risks and establishing levels of 
risk appetite for the group’s principal risks.
The GAR function carries out any additional 
assurance and reports back to the committee.
Speak Up process
Every year, we review our Speak Up 
whistleblowing process to ensure the 
procedures allow proportionate and 
independent investigation and appropriate 
effective follow-up action. The Societal 
Value Committee reviews the outcomes  
of significant investigations and 
remedial actions.
More information on our Speak Up 
process can be found on page 49
External auditor
Auditor independence is an essential part of 
our audit framework and the assurance it 
provides. We confirm ongoing compliance 
with the Competition and Markets 
Authority’s Statutory Audit Services Order. 
Tenure
Our shareholders appointed PwC as the 
group’s external auditor in July 2018, 
following a formal tender process. This is 
the sixth year that PwC has audited the 
group, with Graham Parsons as current lead 
audit partner. We have no immediate plans 
to re-tender the auditor, however, we 
anticipate that it would be conducted to 
coincide with when Graham Parsons is 
required to rotate off after the 2027 audit, 
in accordance with the current regulation 
that requires a tender every ten years. The 
proposed tender date is in the best interests 
of shareholders and the company, as PwC 
has a detailed knowledge of our business, 
an understanding of our industry, and 
continues to demonstrate that it has the 
necessary expertise and capability to 
undertake the audit.
External audit plan
In developing the external audit plan for 
2023/24, PwC carried out a risk assessment 
to identify potential risks of material 
misstatement in the financial statements. 
This risk assessment considered the nature, 
magnitude and likelihood of each identified 
risk, together with relevant controls, to 
identify audit risks. PwC refer to key audit 
matters in the independent auditors’ report 
on pages 133-142, which formed the basis 
of the external audit plan. 
In determining the scope of coverage, PwC 
considered management reporting, the 
group’s legal entity structure, the 2023/24 
financial results and the financial forecast 
for 2024/25. PwC set out details of the 
coverage and the agreed scope in the 
independent auditors’ report on pages 
133-142. The methodology of assessing 
materiality was consistent with the prior 
year and agreed at approximately 5%  
of the three-year average profit before tax, 
adjusted for loss on business disposals, loss 
on significant legal proceedings, major 
impairment and restructuring charges.
Following discussion and challenge, we 
concluded the proposed external audit plan 
was sufficiently comprehensive for the audit 
of the group’s accounts and approved the 
proposed fee.
How we review PwC’s 
performance
Throughout the year, we review the 
ongoing effectiveness and quality of PwC 
and the audit process. We look at several 
factors: the auditors’ reports to the 
committee; Graham Parsons and the PwC 
team’s performance in and outside 
committee meetings; how the PwC team 
interacts with and challenges management; 
and on PwC’s efforts at building 
relationships with the JM team. We ensure 
that we spend sufficient time with the 
auditors without management present as 
part of our assessment.
We considered how PwC challenged 
management’s judgements and 
assumptions on matters highlighted on 
pages 99-101, and asked PwC to confirm  
if those matters had been addressed 
correctly by management. Following 
detailed analysis of the assurance 
completed, PwC agreed with management’s 
judgements and assumptions.
We seek direct feedback from PwC’s 
independent Quality Review Partner to 
review their assessment of the external 
auditor’s key planning judgements and the 
execution of PwC’s response to significant 
risks and reporting. We also ask PwC to 
share with us the results of their internal 
quality inspections of the audit as well as 
those conducted by the FRC. In addition, 
we feel it is important to understand 
management’s opinion of audit quality and 
effectiveness, with the executive directors 
and senior management completing a 
questionnaire on the external auditor 
each year.
How we gather feedback on the 
effectiveness of our external auditor 
and external audit process:
Third-party reviews
•	 External reviews of PwC by the FRC’s audit 
quality review team and the Quality 
Assurance Department of The Institute of 
Chartered Accountants in England 
and Wales.
Information provided by the auditor 
•	 Details on the audit plan delivery and any 
changes to the scope of work.
•	 Assurance on the operation of PwC’s audit 
quality control procedures and insight 
into their outcomes as they relate to the 
audit and key members of audit team.
Management feedback
•	 Survey of audit quality and effectiveness 
by executive directors and senior 
management including 
recommendations for improvement.
•	 Seek assurance on the disclosure process 
for the provision of information to 
the auditor.
Committee assessment
•	 Quality of regular audit reports.
•	 Feedback from committee members and 
regular attendees, including the Group 
Financial Controller and the Director of 
Assurance and Risk.

Provision of non-audit services
Our Non-Audit Services Policy ensures the 
provision of non-audit services is no threat 
to PwC’s independence and objectivity as an 
auditor. In accordance with the FRC’s 
Revised Ethical Standard 2019, the auditor 
can only provide additional services directly 
linked to the audit.
Our policy sets out how approval should be 
obtained before PwC is engaged to provide 
a permitted non-audit service. Services 
likely to cost £25,000 or less must be 
approved by the Chief Financial Officer; 
services likely to cost more than £25,000 
but less than £100,000 must be approved 
by the committee chair. Services likely to 
cost over £100,000 must be approved by 
the committee.
We reviewed compliance with the Non-
Audit Services Policy, details of the 
non-audit services provided by PwC and 
associated fees. Audit-related assurance 
services reported as non-audit services 
related to the review of half-year financial 
information and reporting, amounting to 
£347,750; other non-audit services in the 
year were £8,865, in total representing 7% 
of the audit fee, compared with audit fees 
of £4.8 million. More information on fees 
incurred by PwC for non-audit services, as 
well as the split between PwC’s audit and 
non-audit fees, are in note 4 to the 
accounts, on page 164.
Objectivity and independence
We are responsible for monitoring and 
reviewing the objectivity and independence 
of PwC. We considered the information 
provided by PwC, confirming that no PwC 
employees involved with the audit have 
links or connections to JM, and that 
they complied with the FRC’s Revised 
Ethical Standard. We conclude that PwC 
is independent.
Proposed re-appointment 
of PwC
Following our assessment, we believe that 
PwC provides a robust audit and valuable 
technical knowledge, and is free from 
third-party influence and restrictive 
contractual clauses. As a result, we have 
included a resolution proposing PwC’s 
re-appointment as auditor, and authorised 
the committee to determine PwC’s 
remuneration, in our 2024 Notice of 
Annual General Meeting.

The Committee’s Terms of Reference set out our full 
responsibilities: matthey.com/governance-framework
“The application of our Remuneration 
Policy in 2023/24 balanced our near 
term objectives of incentivising 
improved performance through the 
execution of business transformation 
and simplification with our longer-
term objectives of creating sustainable 
value creation and growth underpinned 
by a high performance culture.”
Our approach to remuneration 
Our overall purpose at Johnson Matthey  
is catalysing the net zero transition. We 
currently have an important role to play in 
this process through the application of our 
sustainable technologies, products and 
services and we will have an increasingly 
important role to play as we further 
commercialise long-term sustainable 
technologies, including our portfolio of 
hydrogen technologies, which will enable 
decarbonisation and enhance circularity.
Our Remuneration Policy has been 
purposefully designed to support our 
strategy detailed above. Our pay model, 
while market consistent, is weighted 
towards long term variable pay which 
supports the long term nature of the 
investment decisions we make. Our 
Executive Directors’ remuneration includes 
base salary, pension and benefits, annual 
bonus, a performance share plan and share 
ownership requirements with the same 
policy generally cascading below to our 
leaders and senior managers. However, 
below director level, we do operate 
alternative incentives, including restricted 
stock, to ensure we can compete for the 
best executive talent in the geographic 
locations in which we operate.
Remuneration 
Committee report
Dear Stakeholder
I would like to thank those shareholders 
who provided feedback on remuneration 
matters ahead of our 2023 AGM. I was 
pleased that our Directors’ Remuneration 
Policy and Annual Report on Remuneration 
received 89.08% and 94.96% shareholder 
support respectively, reflecting the ongoing 
support from shareholders of our approach 
to remuneration. We expect our 2023 
Remuneration Policy to operate until our 
2026 AGM.
As this is my first report as Chair of the 
committee, following my appointment on 
2nd January 2024, I would like to thank my 
predecessor, Chris Mottershead, for his 
leadership of the committee and support 
during my transition to Chair.
I am pleased to present the Directors’ 
Remuneration Report for the year ended 31st 
March 2024. This report is divided into three 
sections: my statement, a summary of the 
Directors’ Remuneration Policy 
and our Annual Report on 
Remuneration for the year 
ended 31st March 2024.

Overview of company 
performance
The 2023/24 financial year has been a year 
of strong strategic progress and good 
financial performance in challenging 
macroeconomic conditions. We continued 
to transform our business to create a more 
streamlined organisation and have 
delivered £120 million of total cost savings 
to date. We also achieved key milestones in 
relation to winning ‘first of a kind’ projects 
in sustainable fuels and low carbon 
hydrogen. These steps ensure we have a 
stronger platform for future growth. 
With regard to financial performance, 
notwithstanding continued destocking 
across a number of our markets, we 
achieved growth in underlying profit 
(at constant exchange rates and adjusting 
for lower precious metal prices) of 11%, 
delivering a total underlying operating 
profit of £410 million. 
2023/24 incentive plan outcomes
Annual Incentive Plan (AIP)
The maximum bonus opportunity for 
2023/24 remained unchanged at 180%  
of salary for the Chief Executive and 150% 
of salary for the Chief Financial Officer. 
The bonus was based on underlying profit 
before tax (PBT) (50%), working capital 
(20%) and strategic and transformation 
objectives (30%). 
Bonus targets for PBT were set to be 
consistent with the board’s 2023/24 
objective of delivering growth in underlying 
operating profit, adjusted for metal prices 
and exchange rates, of 7.5%. The actual 
growth in underlying operating profit 
achieved on this basis was 11% which was 
an excellent result in challenging market 
conditions. This growth resulted in the PBT 
target, also adjusted for metal prices and 
exchange rates, being achieved at 111.7% 
which was above the top end of the 
performance range which was set at 110% 
of the target. However, after considering 
the range of assumptions used to set the 
original targets, including market 
uncertainty, and then testing the targets 
based 50% on constant metal prices and 
50% on actual metal prices, the committee 
concluded that it was appropriate to 
increase the original targets after the 
standard restatement for metal prices and 
exchange rates to ensure that they had the 
degree of stretch originally envisaged 
allowing for changes to market conditions 
through the year. As a result, the 
committee used its discretion to increase 
the original PBT target by circa. 5%. This 
adjustment resulted in increased 
performance requirements at all 
performance levels given the targets were 
set at 90% to 110% of the target. Following 
the increase to the target, the extent of 
achievement was reduced to 106.6% of 
target from 111.7% which resulted in the 
bonus earned in relation to PBT reducing 
from 100% of maximum to 83% of 
maximum. Overall, a total bonus of 67% of 
maximum was payable to both Liam 
Condon and Stephen Oxley. The committee 
is satisfied that this is a fair outcome in the 
context of the wider stakeholder experience 
and reflective of the overall business 
performance delivered during the year. One 
half of the bonus payable will be deferred in 
shares for a period of three-years. More 
details on the performance against the 
annual targets and strategic objectives are 
set out on pages 120-121.
Performance Share Plan (PSP)
Our Chief Executive and Chief Financial 
Officer were both granted PSP awards in 
August 2021 that were eligible to vest 
based on performance against challenging 
EPS growth and relative TSR performance 
conditions tested over the three year period 
ending 31st March 2024. In light of the 
challenging market conditions across the 
three year period, the performance 
conditions were not met and so the  
awards will lapse. 
The Remuneration Committee, having had 
regard to the remuneration outcomes 
across the group, including considering the 
relationship between executive and wider 
workforce pay, are satisfied that the 
remuneration outcomes are appropriate 
and that the Remuneration Policy operated 
as intended during the year. 
Applying the Remuneration 
Policy in 2024/25
Base Salary 
During the year the Committee reviewed 
the salary increase budgets for the 
workforce taking into account inflation and 
its associated impact on the cost of living. 
The salary increase budget in the UK is 4% 
for non-management roles and 3% for 
management roles. With regards to the 
Executive Directors, the Committee 
considered the UK salary budget along with 
institutional investor guidance on UK 
Director salaries that in a high inflation 
environment increases should be at a 
discount to the workforce and increased  
the Executive Director salaries by 3% with 
effect from 1st April 2024.
AIP
The maximum opportunity will remain at 
180% of salary for the CEO and 150% of 
salary for the CFO and the target will 
continue to be set at 50% of the maximum. 
The Committee reviewed the choice of 
performance metrics for the 2024/25 AIP 
and made a modest refinement to better 
reflect the strategic priorities for the year 
ahead. Underlying PBT continued with a 
weighting of 45%, working capital days was 
retained but with a slightly lower weighting 
of 15% (from 20%) and strategic targets 
were also retained with a reduced 
weighting of 25% (from 30%). In light of 
the group-wide focus on cost reduction, a 
new corporate costs metric was included 
with a weighting of 15% of the total 
bonus opportunity. 
The range of targets set for 2024/25 have 
been recalibrated versus those set for 
2023/24 to take account of group 
divestments, current forecast metal prices 
and exchange rates, as well as internal and 
external expectations of future 
performance. The committee considers the 
range of targets to be at least as challenging 
as those set for 2023/24 allowing for 
current market conditions.
PSP
The Remuneration Committee intends to 
grant awards at the same quantum as in 
2024/25, being 250% and 175% of salary 
for the CEO and CFO respectively.
The performance measures, tested over the 
three year period ending 31st March 2027, 
will include a combination of growth in 
underlying EPS (25%), relative total 
Shareholder return (versus the FTSE 31  
to 130 companies but excluding those in 
financial services)(25%), return on capital 
employed (25%) and sustainability 
objectives (25%). 
The range of EPS growth targets will require 
a minimum growth of 5% p.a. for 15% of 
this part of the award to vest, increasing on 
a straight line basis to 13% p.a. growth for 
full vesting. The range of targets were set 
having regard to internal planning, external 
expectations for future growth and wider 
market conditions. The committee 
considers the range of targets set to be 
similarly challenging to those set in 
prior years. 
TSR will be assessed against the constituents 
of the companies ranked 31 to 130 in the 
FTSE All-Share Index (excluding financial 
services companies) to reflect JM’s current 
position in the FTSE. Threshold vesting 
Johnson Matthey  Annual Report and Accounts 2024

Strategic report
Governance
Financial statements
Other information

Remuneration Committee report continued
starts at 25% for median performance, 
increasing on a straight line basis, with 
100% vesting for achieving at least upper 
quartile performance.
Inclusion of a return on capital measure in 
the 2024 award will incentivise delivery of 
the transformation programme across JM 
and aligns with investor focus on our return 
on capital capabilities. Threshold vesting 
starts at 25% for 12% performance, 
increasing on a straight line basis, with a 
100% vesting for achieving 16%.
Our sustainability targets are set as 
challenging structured targets that align 
with increasing the GHG emissions avoided 
through the use of our products and 
solutions, reducing our own GHG (Scope 1 
and Scope 2) and increasing the percentage 
of female representation across our 
management levels. The range of targets 
are disclosed on page 127 and are set to be 
similarly challenging to the financial and 
TSR targets. 
The Remuneration Committee retains 
discretion on vesting to adjust the number 
of shares vesting having had regard to 
underlying performance during the three 
year performance period and/or if it 
considers there to have been the potential 
for a windfall gain on vesting. The factors 
that the committee would consider in 
determining if there had been a windfall 
gain would include, but not be limited to, 
the share price on grant and at the end of 
the period, and performance through 
the period.
Prior to granting the 2024/25 PSP award 
the committee intends to undertake a final 
review of the performance targets allowing 
for the prevailing market conditions versus 
the time at which the proposed targets were 
set. Full details of the intended awards are 
set out on page 127.
Chair and non-executive 
director fees
The fees payable to the Chair and non 
executive directors are reviewed annually. 
In line with the increase in base salaries for 
Executive Directors, the Chair fee and NED 
base fee was increased by 3% (lower than 
the typical 4% salary increase awarded to 
the wider workforce) with effect from 
1st April 2024. 
Wider employee remuneration 
Paying our employees fairly for their role, 
skills, experience and performance is 
central to our approach to remuneration, 
and our reward framework and policies 
support us in doing this.
Equal pay is also critical, and we review our 
pay levels on an ongoing basis to ensure 
that employees are paid fairly. We will 
continue our work in this area over the 
coming year as we prepare for the EU Pay 
Transparency Directive. 
We are also committed to the real living 
wage and narrowing the gender pay gap 
that exists among our employees, and to 
tackling the root causes of gender 
imbalance to ensure a truly inclusive culture 
that supports diversity.
We aspire to offer a well-balanced, 
progressive and structured approach to 
reward, with appropriate variation by 
location. We also find that the non-financial 
reward elements are essential to a 
supportive culture, with the wellbeing  
of staff a prominent part of our 
employment proposition.
This year, all employees were able to 
provide their feedback on a range of 
matters, including remuneration, through 
our annual employee engagement survey 
and local and global town hall meetings.
Committee effectiveness
The externally facilitated board  
and committee effectiveness review 
concluded that the committee continued  
to function effectively.
Shareholder engagement
We were grateful for the feedback we 
received prior to the 2023 AGM from our 
largest investors as well as Institutional 
Shareholder Services (‘ISS’), The Investment 
Association (‘IA’) and Glass Lewis as part of 
the renewal of our Directors’ Remuneration 
Policy. The feedback we received was 
supportive of our general approach to 
Directors’ remuneration and the minor 
refinements we proposed.
We welcome an open dialogue with our 
shareholders, and I will be available at the 
2024 AGM to answer any questions about 
the work of the Remuneration Committee
2024 AGM
The committee believes that the policy and 
our approach to implementation are in the 
best interests of the company.
I ask you to support the advisory vote on this 
Annual Statement and the 2024 Annual 
Report on remuneration at our AGM on 
18th July 2024.

Remuneration Policy
The Directors’ Remuneration Policy was approved at the 2023 AGM on 20th July 2023 and will remain in effect until the 2026 AGM
A summary of the policy is set out below. The full policy can be found on our website https://matthey.com/remuneration-committee 
Remuneration Policy Table
Element
Summary
Potential value of element and performance measures
Base salary
Base salaries will normally be reviewed annually, and any changes normally take effect 
from 1st April each year.
In determining salaries and salary increases, the Remuneration Committee will take 
account of the performance of the individual director against a broad set of parameters 
including financial, environmental, social and governance issues.
The Remuneration Committee will also take into account the director’s knowledge, 
contribution to the role, length of time in post, and any additional responsibilities since 
the last salary review, as well as the level of salary increases awarded to the wider Johnson 
Matthey workforce.
Maximum opportunity
No salary increase will be awarded which results in a base salary 
which exceeds the competitive market range considered 
appropriate by the committee for the role.
Benefits
Benefits include, but are not limited to, medical, life and income protection insurance, 
medical assessments, company sick pay, a company car (or equivalent), relocation 
benefits relating to business moves and assistance with tax advice and compliance 
services where appropriate
Other appropriate benefits may also be provided from time to time at the discretion of the 
Remuneration Committee.
Benefits are not generally expected to be a significant part of the 
remuneration package in financial terms. Car benefits will not 
exceed a total of £25,000 per annum.
The cost of medical insurance for an individual executive director 
and dependants will not exceed £25,000 per annum.
Pension
All executive directors will be eligible to participate in a company pension plan and/or 
paid a cash supplement in lieu of membership in a pension plan. 
The maximum company contribution is 15% of base salary for 
executive directors. This is aligned to the typical cost of providing 
pension benefits to other employees in the UK. 
Annual Incentive Plan
The Remuneration Committee sets the AIP performance measures and targets for each 
new award cycle. At the end of the year, the committee determines the extent to which 
these have been achieved. The committee retains the discretion to reduce any bonus 
award if, in its opinion, the underlying financial performance of the company has not 
been satisfactory in the circumstances.
Of any bonus paid, up to 50% is paid in cash and the remaining balance is deferred into 
shares for a three-year period as an award under the deferred bonus plan.
Maximum opportunity and vesting thresholds
•	 Chief Executive Officer – 180% of base salary.
•	 Other executive directors – 150% of base salary.
Where financial measures are set the threshold performance 
level will result in a bonus of up to 25% of the target bonus 
opportunity. On-target performance will result in 50% payment 
of the maximum opportunity. Where non-financial targets are 
set, it may not be practicable to set targets on a sliding scale.

Element
Summary
Potential value of element and performance measures
Performance Share 
Plan
Shares may be awarded each year and are subject to performance conditions tested over a 
minimum three- year performance period. Subject to the performance conditions being 
met the shares will vest after which the directors will be required to hold any vested shares 
until the fifth anniversary of the award.
Award levels and vesting thresholds
The maximum award level is 250% of salary.
The current award levels are:
•	 Chief Executive Officer – 250% of base salary
•	 Other Executive Directors – 175% of salary.
Threshold performance will result in vesting of up to a maximum 
of 25% for each performance measure. 
All employee share 
plan
Executive directors are entitled to participate in the company’s all-employee plan under 
which regular monthly share purchases are made and matched with the award of 
company shares, subject to retention conditions.
Executive directors would also be entitled to participate in any other all-employee 
arrangements that may be established by the company on the same terms as all 
other employees.
Executive directors are entitled to participate up to the same 
limits in force from time to time for all employees.
Shareholding 
requirements
Executive directors are expected to build up a shareholding in the company over a 
reasonable period of time, and upon cessation of employment are expected to retain a 
shareholding for a period of up to two years. 
The minimum shareholding requirement while an executive 
director and for the two-year period after cessation of 
employment is as follows:
•	 Chief Executive Officer – 250% of base salary.
•	 Other executive directors – 200% of base salary.
Non-executive 
director fees
Non-executive director fees are determined by the board and the non-executive directors 
exclude themselves from these discussions.
The fees for the Chair are determined by the Remuneration Committee taking into 
account the views of the Chief Executive Officer. The Chair excludes himself from 
these discussions.
Non-executive directors are paid a base fee each year with an additional fee for each 
committee Chair or additional role held.
Non-executive director fees are reviewed every year. 
The fee levels are set subject to the maximum limits set out in 
the company’s Articles of Association.

Remuneration Policy continued
The committee is responsible for determining, and agreeing with the board, the Directors’ Remuneration Policy and has oversight of its implementation. The committee has clear terms of 
reference, works with management and independent advisers to develop proposals and recommendations, and exercises independent judgement when making decisions. This process is 
considered to manage any potential conflicts of interest.
The policy is performance focused and, given the long-term nature of JM’s business, is weighted towards long-term performance and includes market standard shareholding expectations  
and recovery and withholding provisions.
The committee considered the principles listed in the UK Corporate Governance Code 2018 when reviewing the Directors’ Remuneration Policy and took these into account in its design  
and implementation.
Clarity
Remuneration arrangements have defined parameters which can be transparently communicated to shareholders and other stakeholders.
Simplicity
Remuneration arrangements for executive directors consist of:
•	 Salary, benefits, and a fixed pension contribution – set to reflect the typical rate provided to the UK workforce.
•	 Annual Incentive Plan (AIP), a portion of which is deferred into shares.
•	 Annual long-term Performance Share Plan (PSP) awards which provide focus on performance over the longer term.
Unnecessary complexity is avoided by the committee in operating the arrangements. 
Risk
The remuneration arrangements are designed to have a robust link between pay and performance, thereby mitigating the risk of excessive reward. 
In addition, behavioural risks are considered when setting targets for performance-related pay, and the arrangements have safeguards to ensure that pay 
remains appropriate, including committee discretion to adjust incentive outturns, deferral of incentive payments in shares, recovery provisions and share 
ownership requirements. To avoid conflicts of interest, committee members are required to disclose any conflicts or potential conflicts ahead of committee 
meetings. No executive director or other member of management is present when their own remuneration is under discussion.
Predictability
The committee set specific targets for different levels of performance which are communicated to the individuals and disclosed to shareholders.
Proportionality
The AIP and PSP have performance metrics that are aligned with the company’s KPIs, and the payouts reflect achievement against the targets. 
The committee may reduce payouts under the AIP and PSP if they are not considered aligned with underlying performance. Safeguards are identified  
to ensure that poor performance is not rewarded.
Alignment to culture
The directors’ remuneration arrangements are cascaded through the organisation ensuring that there are common goals. The committee reviews 
remuneration arrangements throughout the company and takes these into account when setting directors’ remuneration.

Remuneration Policy continued
Selection of performance targets
Annual Incentive Plan
Financial performance targets under the AIP are set by the Remuneration Committee with 
reference to the prior year and to the budgets and business plans for the coming year, ensuring 
the levels to achieve threshold, target or maximum payout are appropriately challenging.
The performance targets for 2024/25 are predominantly based on financial measures 
(75% of maximum opportunity) including underlying PBT, working capital days and 
corporate cost reduction to ensure that there is strong attention paid to delivery of current 
operational plans and operational efficiency.
Commercial sensitivity precludes the advance publication of the actual bonus targets, 
but these targets will be retrospectively published in the Annual Report on Remuneration 
for 2024/25.
Performance Share Plan
The performance targets under the PSP are set to reflect the company’s longer-term  
growth objectives at a level where the maximum represents genuine outperformance. 
The performance measures proposed for the 2024 award are underlying EPS, TSR,  
return on capital employed and strategic objectives.
Underlying EPS is considered a simple and clear measure of absolute growth in line with the 
company’s strategy.
TSR is considered a simple and clear performance relative to a comparator group  
(FTSE 31-130 excluding financial services companies).
Return on capital employed supports our transformation journey and aligns with investor 
focus on our ability to return value on investments.
The strategic objectives will consist of three equally weighted metrics related to our 
sustainability framework.
Discretion
The Remuneration Committee can exercise discretion in a number of areas when operating 
the company’s incentive plans, in line with the relevant rules of the plan. These include (but 
are not limited to):
•	 The choice of participants
•	 The size of awards in any year (subject to the limits set out in the Directors’ 
Remuneration Policy table)
•	 The extent of payments or vesting in light of the achievement of the relevant 
performance conditions
•	The determination of good or ordinary leavers and the treatment of outstanding awards 
(subject to the provisions of the plan rules and the remuneration policy provisions)
•	 The treatment of outstanding awards and assessing performance in the event of a change 
of control.
In addition, if events occur which cause the Remuneration Committee to conclude that any 
performance condition is no longer appropriate, that condition may be substituted, varied or 
waived as is considered reasonable in the circumstances, in order to produce a fairer measure 
of performance that is not materially less difficult to satisfy.

Remuneration scenarios
Below is an illustration of the potential future remuneration that could be received by each executive director for the year starting 1st April 2024, both in absolute terms and as a proportion of 
the total package under different performance scenarios. The value of the PSP is based on the award that will be granted in August 2024. In developing the scenarios, the following 
assumptions have been made:
Below threshold
Only fixed elements of remuneration (base salary, pension and benefits) are payable
Threshold
Fixed elements of remuneration plus 25% of target bonus and 22% vesting of PSP award are payable
Target
Fixed elements of remuneration plus 50% of maximum bonus and 60% vesting of PSP award are payable

Group employee considerations
The Remuneration Committee considers the directors’ remuneration, along with the 
remuneration of the Group Leadership Team (GLT), in the context of the wider employee 
population, and is kept regularly updated on pay and conditions across the group.
We aspire to offer a well-balanced, progressive and structured approach to reward, with 
appropriate variation by location. We also find that the non-financial reward elements are 
essential to a supportive culture, with the wellbeing of staff a prominent part of our 
employment proposition.
The general principle for remuneration in Johnson Matthey is to provide a competitive package  
of pay and benefits in all markets and at all job levels to attract and retain high‑quality  
and diverse employees. Equal and fair pay is also a critical component of our proposition, and we 
regularly review our pay levels and develop actions to remove any form of potential inequality. 
The proportion of variable pay increases with progression through management levels, with 
the highest proportion of variable pay at executive director level, as defined by the 
Remuneration Policy.
This year, all employees were able to provide their feedback on a range of matters, including 
remuneration, through our annual employee engagement survey and townhall meetings. 
This provided valuable employee context to decision making when considering remuneration 
decisions made during the year. While we inform our employees of global changes to pay 
and benefits, we have not actively sought a two-way dialogue over executive pay 
during 2023/24.

The table below sets out how our remuneration arrangements cascade through the organisation:
Executive directors
Senior managers
Middle managers

Base salary
Base salary is set with reference to the relevant local market and takes account of the employee’s knowledge, experience and 
contribution to the role. Base salaries are usually reviewed annually and take into account local salary norms, local wage 
inflation and business conditions. Increases in base salary for directors will take into account the level of salary increases 
granted to all employees within the group.
Base salary is either subject 
to negotiation with local 
trade unions or follows the 
market pay approach 
outlined for managers.
Pension and benefits
Employment-related benefits are offered in line with local market conditions.
Short-term incentives

Shareholder considerations
The committee has a standard annual 
agenda item whereby the feedback from 
shareholders and investor advisory bodies is 
presented and discussed following the AGM. 
The Committee Chair is also available for 
questions at the AGM. The feedback that 
the committee receives then informs 
discussions for the formulation of future 
policy and subsequent remuneration 
decisions. The committee is also regularly 
updated on the collective views of 
shareholders and investor advisory bodies 
by its independent advisor.
Approach to recruitment
The recruitment policy provides an 
appropriate framework within which to 
attract individuals of the required calibre to 
lead a company of Johnson Matthey’s size, 
scale and complexity. The Remuneration 
Committee determines the remuneration 
package for any appointment to an 
executive director position, either from 
within or outside Johnson Matthey.
The following table sets out the various 
components which would be considered for 
inclusion in the remuneration package for 
the appointment of an executive director 
and the approach to be adopted by the 
Remuneration Committee in respect of 
each component.
In the case of an internal promotion to  
the board, the company will honour any 
contractual commitments made prior to 
the promotion.
Remuneration Policy continued
Area
Policy and operation
Overall
The policy of the board is to recruit the best candidate possible for any board position and to structure pay and 
benefits in line with the Remuneration Policy set out in this report. The ongoing structure of a new recruit’s package 
would be the same as for existing directors, with the possible exception of an identifiable buy-out provision, as set 
out below.
Base salary 
or fees
Salary or fees will be determined by the Remuneration Committee in accordance with the principles set out in the 
approved remuneration policy. https://matthey.com/remuneration-committee
Benefits and 
pension
An executive director will be eligible for benefits and pension arrangements in line with the company’s approved 
remuneration policy for current executive directors. https://matthey.com/remuneration-committee
Annual Incentive 
Plan
The maximum level of opportunity is as set out in the policy summary on page 109. The Remuneration Committee 
retains discretion to set different performance targets for a new externally appointed executive director, or to adjust 
performance targets and/or measures in the case of an internal promotion, to be assessed over the remainder of the 
financial year. In this case any bonus payment would be made at the same time as for existing directors, such award 
to be pro-rated for the time served in the performance period.
Performance 
Share Plan
The maximum level of opportunity is as set out in the policy summary on page 110. In order to achieve rapid 
alignment with Johnson Matthey’s and shareholder interests, the Remuneration Committee retains discretion to 
grant a PSP award to a new externally appointed executive director on or soon after appointment if they join outside 
of the normal grant period.
Replacement 
awards buy-out
The Remuneration Committee retains discretion to grant replacement buy-out awards (in cash or shares) to a new 
externally appointed executive director to reflect the loss of awards granted by a previous employer. Where this is the 
case, the Remuneration Committee will seek to structure the replacement award such that overall it is on an 
equivalent basis to broadly replicate that foregone, using appropriate performance terms. If granted, any 
replacement buy-out award would not exceed the maximum set out in the rules of the 2017 Performance Share Plan 
(350% of base salary).
If the executive director’s prior employer pays any portion of the remuneration that was anticipated to be forfeited, 
the replacement awards shall be reduced by an equivalent amount.
Other
The Remuneration Committee may agree that the company will meet certain mobility costs and relocation costs 
including temporary living and transportation expenses, in line with the company’s prevailing mobility policy for 
senior executives as described in the approved remuneration policy https://matthey.com/remuneration-committee
Service contracts and policy on payment for loss of office
The following table summarises relevant key provisions of executive directors’ service contracts and the treatment of payments on  
termination of employment. The full contracts of service of the executive directors (as well as the terms and conditions of appointment  
of the non-executive directors) are available for inspection at the registered office of the company during normal business hours as well as 
prior to and during the forthcoming AGM.
In exceptional circumstances, the Remuneration Committee may authorise, where it considers it to be in the best interests of the company 
and shareholders, entering into contractual arrangements with a departing executive director, for example a settlement, confidentiality, 
restrictive covenant or other arrangement, pursuant to which sums not set out in the following table may become payable. Full disclosure of 
the payments will be made in accordance with the remuneration reporting requirements.
The table on the following page describes the contractual conditions pertaining to the contracts for Liam Condon and Stephen Oxley and for 
any future executive director.

Post-termination restrictions
The contracts of employment contain the following restrictions on the director for the following periods from the date of termination of employment:
•	 non-compete – six months
•	 non-dealing and non-solicitation of client/customers – 12 months
•	 non-solicitation of suppliers and non-interference with supply chain – 12 months
•	 non-solicitation of employees – 12 months.
Summary termination – 
payment in lieu of notice 
(PILON)
The company may, in its absolute discretion, terminate the employment of the director with immediate effect by giving written notice together with 
payment of a sum equivalent to the director’s base salary and the value of his contractual benefits as at the date such notice is given, in respect of the 
director’s notice period, less any period of notice actually worked.
The company may elect to pay the PILON in equal monthly instalments. The director is under a duty to seek alternative employment and to keep the 
company informed about whether they have been successful. If the director commences alternative employment, the monthly instalments shall be 
reduced (if appropriate to nil) by the amount of the director’s gross earnings from the alternative employment. A PILON paid to a director who is a US 
taxpayer would be in equal monthly instalments.
Termination payment – 
change of control
If, within one year after a change of control, the director’s service agreement is terminated by the company (other than in accordance with the 
summary termination provisions), the company shall pay, as liquidated damages, one year’s base salary, together with a sum equivalent to the value of 
the director’s contractual benefits, as at the date of termination, less the period of any notice given by the company to the director.
Termination – treatment of 
annual incentive awards
Annual bonus awards are made at the discretion of the Remuneration Committee.
Executive directors leaving the company’s employment will receive a bonus, pro-rata to service, unless the reason for leaving is resignation or misconduct. 
Any bonus awarded would continue to be subject to deferral as set out in the Remuneration Policy.
In relation to deferred bonus awards which have already been made, shares will be released on the normal vesting date unless one of the following 
circumstances applies, and subject to the discretion of the Remuneration Committee:
•	 the participant leaves as a result of misconduct; or
•	 the participant, prior to vesting, breaches one of the post-termination restrictions or covenants contained in their employment contract, termination 
agreement or similar agreement.
In which case the deferred awards will lapse on cessation of employment.
The Remuneration Committee has the discretion to accelerate vesting of a deferred award if appropriate to do so to reflect the circumstances of the 
departure. It is intended that this would only be used in the event of a departure due to ill health (or death).

Termination – treatment of 
long-term incentive awards
Employees, including executive directors, leaving the company’s employment will normally lose their long-term incentive awards unless they leave for a 
specified “good leaver” reason (e.g. death, retirement), in which case their shares will be released on the normal release dates, subject to the 
performance condition. The Remuneration Committee has discretion to accelerate vesting, in which case the performance condition would be assessed 
based on available information at the time. In either case, unless the Remuneration Committee determines otherwise, the level of vesting shall be 
pro-rated to reflect the proportion of the performance period which has elapsed to the date of leaving. In the post-vesting deferral period, only those 
who leave due to misconduct will lose their shares.
Redundancy arrangements
Directors are not entitled to any benefit under any redundancy payments arrangement operated by the company.
Holiday
Upon termination for any reason, directors will be entitled to payment in lieu of accrued but untaken holiday entitlement.
Chair and Non-Executive Directors
The Chair and each of the non-executive directors have letters of appointment. The letters of appointment do not contain any contractual entitlement to a termination payment and the 
non‑executive directors can be removed in accordance with the company’s Articles of Association. Directors are required to retire at each AGM and seek re-election by shareholders.
The details of the service contracts, including notice periods, contained in the letters of appointment in relation to the non-executive directors who served during the year are set out in the 
table below. Neither the Chair or the non-executive directors has provisions in his or her letter of appointment that relate to a change of control of the company.

The members of the Remuneration Committee are John O’Higgins (Chair), Jane Griffiths, 
Xiaozhi Liu and Doug Webb. Prior to 2nd January 2024, when membership of the Board 
Committees was streamlined, the Remuneration Committee had comprised all six of the 
Company’s non-executive directors. Details of attendance at committee meetings during the 
year ended 31st March 2024 are shown on page 77.
The Remuneration Committee’s Terms of Reference can be found at matthey.com/REM-
terms-of-reference. These include determination of fair remuneration for the group Chair, 
executive directors and senior management, including the General Cousel and Company 
Secretary (no individual participates in discussions of their own remuneration). The General 
Counsel and Company Secretary acts as secretary to the committee.
Advisers to the committee
The committee appoints and receives advice from independent remuneration consultants on 
the latest developments in corporate governance and market trends in pay and incentive 
arrangements. The committee appointed Korn Ferry as adviser to the Remuneration 
Committee after a competitive tender process in 2017. The total fees paid to Korn Ferry in 
respect of its services to the committee during the year were £32,480 +VAT. The fees paid to 
Korn Ferry are based on the standard market rates Korn Ferry has for remuneration 
committee advisory services.
Korn Ferry also provides consultancy services to the company in relation to certain employee 
and benefit matters to those below the Board. Korn Ferry is a signatory to the Remuneration 
Consultants Group Code of Conduct.
The committee is satisfied that the advice provided by Korn Ferry, an unconnected third party, 
was independent and objective and that the provision of additional services did not 
compromise that independence. The committee is also satisfied that the team who provided 
that advice does not have any connection to Johnson Matthey that may impair their 
independence and objectivity.
Herbert Smith Freehills is the committee’s legal adviser. There was no requirement during 
2023/24 for Herbert Smith Freehills to provide advice to the committee. The committee is 
aware that Herbert Smith Freehills is one of a number of legal firms that provide legal advice 
and services to the company on a range of matters.
A statement regarding the use of remuneration consultants for the year ended  
31st March 2024 is available at matthey.com/corporate-governance.

Annual bonus for the year ended 31st March 2024 (audited)
Liam Condon and Stephen Oxley were eligible for a maximum annual bonus of 180% of base 
salary and 150% of base salary, respectively. The target bonus opportunity was set at 50% of 
maximum and the threshold bonus opportunity was 25% of the target opportunity.
The performance measures and weightings for the annual bonus were as follows:

1.	 Group working capital days is split 50% total working capital (including PGMs) and 50% total working capital days (excluding PGMs).
Performance targets were set by looking at:
•	 Previous year financial performance.
•	 Budgets and business plans for 2023/24. These are built from the bottom up and are 
subject to thorough challenge before being finalised by the board.
•	 Consensus of industry analysts’ forecasts, provided by Vara Research.
The committee also considered the performance range for the group profit measures and 
concluded that given the continued uncertainty in the market at the time the targets were set, 
the range should continue to be 90% to 110% of target performance. The 2023/24 targets are 
considered similarly challenging, if not more challenging than those set in 2022/23.
The strategic objectives were set based on well-defined key deliverables that support our 
strategy relating to science, customers, operations and people.
Bonus outcomes (audited)
The underlying PBT target was set to be consistent with a 7.5% growth in underlying operating 
profit. The formulaic outcome based on delivery of 11% underlying growth in operating profit when 
adjusted for metal prices and exchange rates was a 111.7% achievement against the PBT target. 
However, after considering the range of assumptions used to set the original targets, including 
market uncertainty, and then testing the targets based 50% on constant metal prices and 50% on 
actual metal prices, the committee concluded that it was appropriate to increase the original targets 
after the standard restatement for metal prices and exchange rates to ensure that they had the 
degree of stretch originally envisaged allowing for changes to market conditions through the year. 
As a result, the committee used its discretion to increase the original PBT target by circa. 5%. Based 
on performance against the adjusted targets, total bonuses for the year ended 31st March 2024 
were as set out below. The committee is comfortable that the bonuses earned, based on the revised 
targets, are appropriate in the context of the wider stakeholder experience through the year.

No new strategic partnerships were signed in Hydrogen Technologies 
due to the change in market outlook during the year. 
Accelerate cultural transformation with focus on enhancing 
customer orientation, disciplined execution and efficiency by:
•	 Increasing JMs net promoter score
•	 Implementing a new performance management approach
•	 Fully staffing critical engineering capex roles
•	 Set-up of Global Business Services
Good progress has been made in all areas:
•	 JM’s net promoter score has increased by five points versus 2023.
•	 JM’s new performance management and incentivisation approach 
was successfully rolled out, evidenced by improved scoring related to 
objective setting, feedback and development in our pulse surveys. 
•	 We have staffed all critical engineering roles for capex projects.
•	 All key milestones have been achieved without any business 
disruption and ahead of the approved GBS business case.

1.	 The committee assess executive director performance using the same framework that operates across Johnson Matthey. This involves assessing the extent of achievement and categorizing that achievement in performance bands which, for Executive Directors, also involves 
consideration of the overall financial performance achieved over the financial year. As a result, notwithstanding that more than 50% of the strategic objectives set out above were achieved during the year, the bonus out-turn in relation to strategic targets was moderated to 50% of 
the maximum.

Directors’ interests as at 23rd May 2024 were unchanged from those listed above other than 
that the Trustees of the all-employee share matching plan have purchased another 42 shares 
for Liam Condon and 42 shares for Stephen Oxley.
Executive directors are expected to achieve a shareholding guideline of 250% of base salary 
for the Chief Executive Officer and 200% for other executive directors, within a reasonable 
timeframe. The director’s total shareholding for the purposes of comparing it with the 
minimum shareholding requirement includes shares held beneficially by the director and 
any connected persons (as recognised by the Remuneration Committee), together with the 
shares awarded under the Deferred Bonus Plan (DBP), for which there are no further 
performance or service conditions.
Shares that count towards achieving the post-cessation guideline include the same as those 
while an executive director. Executive directors are expected to retain at least 50% of the net 
(after tax) vested shares that are released under the PSP and DBP until the required levels of 
shareholding are achieved.

1.	 Liam Condon was appointed Chief Executive Officer on 1st March 2022, so no change in compensation can be calculated for 2022. No change in bonus can be calculated for 2023 as not eligible in 2022. 
2.	 Stephen Oxley was appointed Chief Financial Officer on 1st April 2021, so no change in compensation can be calculated for 2022.
3.	 Represents the additional fee received for taking the SVC Chair position on 1st June 2021 and annual fee review.

6.	 Rita Forst was appointed to the board on 4th October 2021, so no change in compensation can be calculated for 2022.
7.	 Includes promotions and market adjustments.
8.	 The percentage change in bonus was calculated based on the change in bonus accrual taken for Johnson Matthey Plc (JM Plc) employees, excluding the directors, for the 2023/24, 2022/23, 2021/22 and 2020/21 years. 
9.	 There has been no change to the benefits policy for Johnson Matthey Plc employees; therefore, a 0% change has been reported.

12.	Chris Mottershead stepped down from the board on 26th January 2024.
13.	Barbara Jeremiah was appointed to the board on 1st July 2023 so no change in compensation can be calculated for 2024.
14.	Due to an administrative error, which has been corrected, fees received from October 2021 to April 2023 were £67k but should have been £68,350. Change in remuneration reflects the change from what the correct fees for 2023 should have been rather than what was actually paid.

Chief Executive Officer to employee pay ratio
The table below shows the ratio of Chief Executive Officer to employee pay between 2020 
and 2024. We have compared the single total figure of remuneration for the Chief Executive 
Officer to the total pay and benefits of UK employees, on a full-time equivalent basis, who 
are ranked at the lower quartile, median and upper quartile across all UK employees effective 
31st March 2024.
We believe that using total pay and benefits for the year ending 31st March 2024 provides a 
like-for-like comparison to the Chief Executive Officer pay data.

37:1 to 30:1, median from 49:1 to 42:1 and lower quartile from 60:1 to 53:1.
2.	 The Chief Executive Officer single figure for 2021/22 is in respect of both Robert MacLeod and Liam Condon, who both held the position 
of Chief Executive Officer in the year. The single total figure of £1,672,000 comprises £1,557,000 for Robert MacLeod and £115,000 for 
Liam Condon.
Bonus data for UK employees was left out of the 2024 calculation because it was not 
administratively possible to calculate these bonuses before the publication of this report. 
However, the calculation will be revised to include these bonuses once available and will be 
disclosed in the 2025 report. 
Excluding the 2023/24 bonus payable to the Chief Executive Officer from the calculation 
would result in the following pay ratios: lower quartile – 29:1, median – 23:1 and upper 
quartile – 17:1.
The salary and total pay for the individuals identified at the lower quartile, median and upper 
quartile positions in 2024 are set out below:

1.	 Includes shift allowance.
Our principles for pay setting and progression are consistent across the organisation. 
Underpinning our principles is a need to provide a competitive total reward to enable the 
attraction and retention of high-calibre individuals and giving the opportunity for individual 
development and career progression. The pay ratios reflect the difference in role 
accountabilities that are recognised through our pay structures and the greater variable pay 
opportunity for more senior positions. The Chief Executive Officer’s variable pay opportunity 
is higher than those employees noted in the table reflecting the weighting towards long-
term value creation and alignment with shareholder interests inherent in this role.
The movement in our Chief Executive Officer to employee pay ratio between 2020 and 2024 
is driven by the different bonus outcomes and fixed income for the Chief Executive Officer in 
each of these years. There have been no other changes to remuneration arrangements for 
our UK employees that would affect the CEO pay ratio.
We are satisfied that the median pay ratio is consistent with our wider pay, reward and 
progression policies for employees. All our employees have the opportunity for annual pay 
increases, career progression and development opportunities.

Implementing the Directors’ Remuneration Policy for 2024/25
The table below sets out how the Remuneration Committee intends to apply the Directors’ Remuneration Policy for the year ended 31st March 2025.
Salary
The Chief Executive Officer and Chief Financial Officer both received a pay increase of 3%. This is in line with the pay increases for management employees in the UK but below the 
increase awarded to non-management UK employees.
Benefits
No change to policy applied in 2023/24.
Pension
All executive directors will have a maximum pension cash supplement of 15%.
Annual 
incentives
The maximum bonus opportunity for 2024/25 remains unchanged at 180% of salary for the Chief Executive Officer and 150% of salary for the Chief Financial Officer.
2024/25 bonus will be based on underlying profit before tax (45%), working capital (15%), corporate cost reduction (15%) and strategic and transformation objectives (25%). 
Targets for the Chief Executive Officer and Chief Financial Officer will be based on group performance. 
The 2024/25 targets are considered similarly challenging, if not more challenging to those set in 2023/24, when accounting for the divestments in the year and uncertain economic 
outlook. Targets have been set taking this into account as well as internal and external planning. To the extent that metal prices move outside a defined corridor the Remuneration 
Committee will rebase the targets such that they are similarly challenging as when the targets were originally set. The Remuneration Committee considers the forward-looking targets 
to be commercially sensitive but full retrospective disclosure of the actual targets will be included in next year’s Directors’ Remuneration report.
50% of any bonus paid will be deferred in shares for three years, and the payment of any bonus is subject to appropriate malus and clawback provisions.
Long-term 
incentives
The Chief Executive Officer award level is 250% of base salary and the Chief Financial Officer award level is 175% of base salary. These award levels are in line with our remuneration policy. 
The long-term Performance Share Plan will be based on EPS growth targets (25% of the award), relative TSR performance (25% of the award), return on capital employed (25%) and 
specific and measurable strategic objectives (25% of award).
The range of annualised EPS growth targets that the committee intends to set for the 2024/25 awards is 5% per annum growth for threshold (15%) vesting, rising to 13% per annum 
growth for maximum vesting (100%). Vesting will be on a straight-line basis between 5% and 13%. The committee considered the effect of metal price volatility on potential 
outcomes and, as a result, earnings will be assessed 50% against actual metal prices and 50% against constant metal prices. The committee believes that this will allow for a more 
accurate assessment of underlying business performance.
The ROCE targets that the committee intends to set for the 2024/25 awards is 12% for threshold (25%) vesting rising to 16% for maximum (100%) vesting. Vesting will be on a 
straight-line between 12% and 16% ROCE. As detailed in the Chair’s statement, the range of EPS and ROCE targets have been set to be challenging with reference to internal 
planning, external expectations for our future performance and wider market conditions. ROCE has been introduced as a measure to align with the successful delivery of our 
transformation programme and driving improved returns on our capital employed.
The TSR target will be 25% vesting for median performance, increasing on a straight-line basis to 100% vesting for upper quartile performance. The TSR peer group will be the FTSE 
31 – 130 (excluding financial services companies). The committee considers that this comparator group is the most appropriate given our current market capitalisation.
The strategic objectives scorecard will consist of three equally weighted metrics. Threshold vesting will be 25%, increasing on a straight-line basis to 100% at maximum. The three 
metrics are as follows:
•	 Products and services – tonnes of GHG avoided during the period using technologies enabled by our products and solutions, compared to conventional solutions, where threshold 
vesting will be 4 million tonnes GHG avoided and maximum will be 10 million tonnes GHG avoided.
•	 Operations – reduction in Scope 1 and 2 GHG emissions (from the 2020 baseline), where threshold vesting will be achieved for a 32% reduction in GHG emissions and maximum 
vesting for a 36% reduction in GHG emissions.
•	 People – percentage of female representation across our management levels, where threshold vesting will be achieved at 33% female representation at management levels and 
maximum at 35% female representation at management levels.
Awards vest in year three and are then subject to a two-year holding period.
Chairman and 
non-executive 
director fees
The fees for the Chair and non-executive directors were reviewed during the year and increased in line with the increase awarded to executive directors.

Further information and a mandate can be obtained from our registrar, Equiniti, whose details can be found on page 220, and on our website: matthey.com
Directors’ 
indemnities  
and insurance
Johnson Matthey Plc has granted indemnities to each Johnson Matthey Plc director and the directors of the group’s subsidiaries in respect of certain liabilities 
arising against them in the course of their duties. Neither Johnson Matthey Plc nor any subsidiary has indemnified any director of the company or a subsidiary 
in respect of any liability that they may incur to a third party in relation to a relevant occupational pension scheme. The company maintains appropriate 
directors’ and officers’ liability insurance.
Conflicts of interest 
The board has a policy for identifying and managing directors’ conflicts of interest, which extends to cover close family members. The board annually reviews 
external appointments to consider any potential or actual conflict of interest. If a conflict of interest is declared, the board will review the authorisation and 
terms associated, to ensure that all matters presented to the board are considered solely with a view to promoting JM’s business success. For the year under 
review, there were no potential or actual conflicts of interest.
External 
appointments
The board approves all external appointments in advance of acceptance. If an external appointment arises between meetings, this is considered by the Chair 
and Chief Executive Officer, with the assistance of the General Counsel and Company Secretary. In approving each additional external appointment, the board 
assesses time commitment to ensure that no directors are considered over-boarded.
Directors’ 
reappointment
Johnson Matthey Plc’s Articles of Association (the Articles) provide the rules on director appointments and are consistent with the recommendation contained 
within the UK Corporate Governance Code 2018. All directors retire and are eligible for re-election at each Annual General Meeting (AGM) (except any director 
appointed after the notice of an AGM meeting is published and before that AGM is held).
Directors’ powers
The powers of the directors are determined by the Articles, UK legislation including the 2006 Act, and any directions given by the company in general 
meetings. The directors are authorised by the company’s Articles to issue and allot ordinary shares and to make market purchases of its own shares. 
These powers are referred to shareholders for renewal at each AGM. Further information is set out on page 130 under ‘Authority to purchase own shares’.

Constitution
Articles of Association
The Articles may only be amended by a special resolution at a general meeting of the company. The Articles were adopted on 17th July 2019 and are available 
on our website: matthey.com/corporate-governance.
Branches
The company and its subsidiaries have established branches in several different countries in which they operate.
Change of control
As at 31st March 2024 and as at the date of approval of this Annual Report and Accounts, there were no significant agreements, to which the company or any 
subsidiary was or is a party to, that take effect, alter or terminate on a change of control of the company, whether following a takeover bid or otherwise. 
However, the company and its subsidiaries were, as at 31st March 2024, and as at the date of approval of this report, party to a number of commercial 
agreements. These may allow counterparties to alter or terminate the commercial agreements on a change of control of JM following a takeover bid. 
These are not deemed significant in terms of their potential effect on the group.
The group also has a number of loan notes and borrowing facilities that may require prepayment of principal and payment of accrued interest and breakage 
costs if there is a change of control of JM. The group has entered into a series of financial instruments to hedge its currency, interest rate and metal price 
exposures, which provide for termination or alteration if a change of control at JM materially weakens the creditworthiness of the group. 
The executive directors’ service contracts each contain a provision to the effect that, if the contract is terminated by the company within one year after a 
change of control of the company, JM will pay an amount equivalent to one year’s gross base salary and other contractual benefits, less the period of any 
notice given by the company, to the director as liquidated damages. 
The rules of the company’s employee share schemes set out the consequences of a change of control of the company on participants’ rights under the 
schemes. Generally, the rights will vest and become exercisable on a change of control, subject to the satisfaction of relevant performance conditions.  
As at 31st March 2024, and as at the date of approval of this Annual Report and Accounts, there were no other agreements between the company, 
any subsidiaries and directors or employees, providing compensation for loss of office or employment (through resignation, purported redundancy  
or otherwise) that occurs due to a takeover bid. 
Stakeholders and policies
Suppliers
We recognise the importance of good supplier relationships to our overall success. Further information on our payment practices is on the UK Government’s 
reporting portal.

Political donations
No political donations or contributions to political parties under the 2006 Act have been made during the year. The group policy is that no political donations 
be made or political expenditure incurred. 
Events occurring after 
the reporting period
There have been no material events affecting Johnson Matthey Plc or any subsidiary between 31st March 2024 and 22nd May 2024.

AGM
Our 2024 AGM will be held on Thursday 18th July 2024 at 11.00 am at Herbert Smith Freehills, Exchange House, Primrose Street, London EC2A 2EG. We will 
provide a live webcast and telephone conference so shareholders can also participate virtually and ask questions in real time. Details on how to join are 
included in the Notice of AGM (Notice). In the Notice, we propose separate resolutions on each substantially separate issue. For each resolution, shareholders 
may direct their proxy to vote either for or against or to withhold their vote. A ‘vote withheld’ is not legally a vote and will not be counted in the calculation of 
the proportion of the votes cast. All AGM resolutions are decided by a poll, with the results announced as soon as possible and posted on our website. This poll 
will show votes for and against, as well as votes withheld.
Authority to purchase 
own shares
At the 2023 AGM, shareholders authorised Johnson Matthey Plc to make market purchases of up to 18,345,341 ordinary shares of 110 49/53 pence each, 
representing 10% of the then issued share capital of the company (excluding treasury shares). Any shares so purchased by the company may be cancelled or 
held as treasury shares. This authority will cease at the conclusion of the 2024 AGM, and shareholders will be asked to give a similar authority at the AGM.
There were no share allotments during the year.
Rights and obligations 
attaching to shares
The rights and obligations attaching to the ordinary shares in Johnson Matthey Plc are set out in the Articles.
As at 31st March 2024, and as at the date of approval of this Annual Report and Accounts, there were no restrictions on the transfer of ordinary shares in the 
company, no limitations on the holding of securities and no requirements to obtain the approval of the company, or of other holders of securities in Johnson 
Matthey Plc, for a transfer of securities – except as referred to below. The directors may, in certain circumstances, refuse to register the transfer of a share in 
certificated form that is not fully paid up, where the instrument of transfer does not comply with the requirements of the company’s Articles, or if entitled 
under the Uncertificated Securities Regulations 2001. As at 31st March 2024 and as at the date of approval of this Annual Report and Accounts:
•	 No person held securities in Johnson Matthey Plc carrying any special rights with regard to control of the company.
•	 There were no restrictions on voting rights (including any limitations on voting rights of holders of a given percentage or number of votes or deadlines for 
exercising voting rights), except that a shareholder can only vote in respect of a share if it is fully paid.
•	 There were no arrangements by which, with the company’s co-operation, financial rights carried by shares in the company are held by a person other than the 
holder of the shares.
•	 There were no agreements known to the company between holders of securities that may result in restrictions on the transfer of securities or on voting rights.
Nominees, financial 
assistance and liens
During the year:
•	 No shares in Johnson Matthey Plc were acquired by the company’s nominee, or by a person with financial assistance from the company, in either case where 
the company has a beneficial interest in the shares (and no person acquired shares in the company in any previous financial year in its capacity as the 
company’s nominee or with financial assistance from the company).
•	 The company did not obtain or hold a lien or other charge over its own shares.
Allotment of securities 
for cash and placing of 
equity securities
During the year neither Johnson Matthey Plc nor any major subsidiary undertaking of the company has allotted equity securities for cash. During the year, 
JM has not participated in any equity securities’ placing.
American Depositary 
Receipt programme
Johnson Matthey has a sponsored Level 1 American Depositary Receipt (ADR) programme, which BNY Mellon administers and for which it acts as Depositary. 
Each ADR represents two ordinary Johnson Matthey shares. The ADRs trade on the US over-the-counter market under the symbol JMPLY. When dividends are 
paid to shareholders, the Depositary converts those dividends into US dollars, net of fees and expenses, and distributes the net amount to ADR holders.
Employee share 
schemes
As at 31st March 2024, 3,458 current and former employees were shareholders in Johnson Matthey Plc through the group’s employee share schemes. Through these 
schemes, current and former employees held 2,940,525 ordinary shares or 1.52% of issued share capital, excluding treasury shares. Also as at 31st March 2024, 
2,829,146 ordinary shares had been awarded but had not yet vested, under the company’s long-term incentive plans, to 363 current and former employees.
Shares acquired by employees through JM’s employee share schemes rank equally with the other shares in issue and have no special rights. Voting rights in 
respect of shares held through the company’s employee share schemes are not exercisable directly by employees. However, employees can direct the trustee 
of the schemes to exercise voting rights on their behalf. The trustee of the company’s Employee Share Ownership Trust (ESOT) has waived its right to 
dividends on shares held by the ESOT, which have not yet vested unconditionally to employees.

Statement of directors’ 
responsibilities in respect  
of the Annual Report and 
Accounts 2024
The directors are responsible for preparing 
the Annual Report and Accounts and the 
financial statements in accordance with 
applicable law and regulation.
Company law requires the directors to 
prepare financial statements for each 
financial year. Under that law, the directors 
have prepared the group financial 
statements in accordance with UK-adopted 
international accounting standards and the 
parent company financial statements in 
accordance with United Kingdom Generally 
Accepted Accounting Practice (United 
Kingdom Accounting Standards, comprising 
FRS 101 ‘Reduced Disclosure Framework’, 
and applicable law).
Under company law, directors must not 
approve the financial statements unless 
they are satisfied that they give a true and 
fair view of the state of affairs of the group 
and parent company and of the profit or 
loss of the group for that period. In 
preparing the financial statements, the 
directors are required to:
•	 select suitable accounting policies and 
then apply them consistently;
•	 state whether applicable UK-adopted 
international accounting standards have 
been followed for the group financial 
statements and United Kingdom 
Accounting Standards, comprising FRS 
101 have been followed for the parent 
company financial statements, subject to 
any material departures disclosed and 
explained in the financial statements;
•	 make judgements and accounting 
estimates that are reasonable and 
prudent; and
•	 prepare the financial statements on  
the going concern basis unless it is 
inappropriate to presume that the group 
and parent company will continue 
in business.
The directors are responsible for 
safeguarding the assets of the group and 
parent company and hence for taking 
reasonable steps for the prevention and 
detection of fraud and other irregularities.
The directors are also responsible for 
keeping adequate accounting records that 
are sufficient to show and explain the 
group’s and parent company’s transactions 
and disclose with reasonable accuracy at 
any time the financial position of the group 
and parent company and enable them to 
ensure that the financial statements and 
the Directors’ Remuneration Report comply 
with the Companies Act 2006.
The directors are responsible for the 
maintenance and integrity of the parent 
company’s website. Legislation in the UK 
governing the preparation and 
dissemination of financial statements may 
differ from legislation in other jurisdictions.
Directors’ confirmations
The directors consider that the Annual 
Report and Accounts 2024, taken as a 
whole, is fair, balanced and understandable 
and provides the information necessary for 
shareholders to assess the group’s and 
parent company’s position and 
performance, business model and strategy.
Each of the directors, whose names and 
functions are listed in the Governance 
section of the Annual Report and Accounts 
2024, confirm that, to the best of 
their knowledge:
•	 the group and parent company financial 
statements, which have been prepared  
in accordance with UK-adopted 
international accounting standards, 
give a true and fair view of the assets, 
liabilities and financial position of 
the group; 
•	 the parent company financial statements, 
which have been prepared in accordance 
with United Kingdom Accounting 
Standards, comprising FRS 101, give a 
true and fair view of the assets, liabilities 
and financial position of the parent 
company; and
•	 the Strategic report includes a fair review 
of the development and performance of 
the business and the position of the group 
and parent company, together with a 
description of the principal risks and 
uncertainties that it faces.
•	 In the case of each director in office at the 
date the Directors’ report is approved:
•	 so far as the director is aware, there is no 
relevant audit information of which the 
group’s and parent company’s auditors 
are unaware; and
•	 they have taken all the steps that they 
ought to have taken as a director in order 
to make themselves aware of any relevant 
audit information and to establish that 
the group’s and parent company’s 
auditors are aware of that information.
The Directors’ report and responsibilities

Report on the audit of the financial statements
Opinion
In our opinion:
•	 Johnson Matthey Plc’s group financial statements and company financial statements 
(the “financial statements”) give a true and fair view of the state of the group’s and of the 
company’s affairs as at 31 March 2024 and of the group’s profit and the group’s cash flows 
for the year then ended;
•	 the group financial statements have been properly prepared in accordance with  
UK-adopted international accounting standards as applied in accordance with the 
provisions of the Companies Act 2006;
•	 the company financial statements have been properly prepared in accordance with 
United Kingdom Generally Accepted Accounting Practice (United Kingdom Accounting 
Standards, including FRS 101 “Reduced Disclosure Framework”, and applicable law); and
•	 the financial statements have been prepared in accordance with the requirements of the 
Companies Act 2006.
We have audited the financial statements, included within the Annual Report and Accounts 
(the “Annual Report”), which comprise: Consolidated Statement of Financial Position and 
Parent Company Statement of Financial Position as at 31 March 2024; the Consolidated 
Income Statement and Consolidated Statement of Total Comprehensive Income, the 
Consolidated Statement of Cash Flows, the Consolidated Statement of Changes in Equity and 
Parent Company Statement of Changes in Equity for the year then ended; and the notes to 
the financial statements, comprising material accounting policy information and other 
explanatory information.
Our opinion is consistent with our reporting to the Audit Committee.
Basis for opinion
We conducted our audit in accordance with International Standards on Auditing (UK) (“ISAs 
(UK)”) and applicable law. Our responsibilities under ISAs (UK) are further described in the 
Auditors’ responsibilities for the audit of the financial statements section of our report. We 
believe that the audit evidence we have obtained is sufficient and appropriate to provide a 
basis for our opinion.
Independence
We remained independent of the group in accordance with the ethical requirements that are 
relevant to our audit of the financial statements in the UK, which includes the FRC’s Ethical 
Standard, as applicable to listed public interest entities, and we have fulfilled our other 
ethical responsibilities in accordance with these requirements.
To the best of our knowledge and belief, we declare that non-audit services prohibited by the 
FRC’s Ethical Standard were not provided.
Other than those disclosed in note 4, we have provided no non-audit services to the company 
or its controlled undertakings in the period under audit.
Our audit approach
Overview
Audit scope
•	 We conducted full scope audits at 17 business units for group reporting purposes. 
In addition, we performed specified procedures over targeted balances and transactions  
at a further 15 business units.
•	 The business units on which audit procedures were performed together account for 84% of 
group revenue and 62% of group underlying profit before tax from continuing operations.
•	 As part of the group audit supervision process, the group engagement team met with and 
discussed the approach and results of audit procedures with component teams and 
reviewed a selection of audit files and final deliverables. In-person site visits to components 
in the UK, China, South Africa, the US and North Macedonia were also performed.
•	 The group engagement team audited the company and other centralised functions including 
those covering the group treasury operations, corporate taxation, post-retirement benefits, 
and certain goodwill and intangible asset impairment assessments. The group engagement 
team also performed audit procedures over the group consolidation and financial 
statements disclosures and performed group level analytical procedures over out of 
scope components.
•	 The group engagement team performed substantive procedures over all of the material 
balances and transactions of the Parent Company.

Key audit matters
•	 Refinery metal accounting (group and parent)
•	 Carrying value of goodwill (group and parent)
•	 Claims, uncertainties and other provisions (group and parent)
Materiality
•	 Overall group materiality: £20.1 million (2023: £21.1 million) based on approximately 5% 
of the three year profit before tax from continuing operations, adjusted for loss on disposal 
of businesses, gains and losses on significant legal proceedings, major impairment, 
amortisation of acquired intangibles and restructuring charges (“underlying profit 
before tax”).
•	 Overall company materiality: £70.6 million (2023: £60 million) based on approximately 
1% of total assets. However, materiality is capped at £19.5 million (2023: £20 million) 
for the purpose of the audit of the consolidated financial statements, being the maximum 
allocation of group materiality to a component.
•	 Performance materiality: £15.1 million (2023: £15.8 million) (group) and £14.6 million 
(2023: £15 million) (company).
The scope of our audit
As part of designing our audit, we determined materiality and assessed the risks of material 
misstatement in the financial statements.
Key audit matters
Key audit matters are those matters that, in the auditors’ professional judgement, were of 
most significance in the audit of the financial statements of the current period and include 
the most significant assessed risks of material misstatement (whether or not due to fraud) 
identified by the auditors, including those which had the greatest effect on: the overall audit 
strategy; the allocation of resources in the audit; and directing the efforts of the engagement 
team. These matters, and any comments we make on the results of our procedures thereon, 
were addressed in the context of our audit of the financial statements as a whole, and in 
forming our opinion thereon, and we do not provide a separate opinion on these matters.
This is not a complete list of all risks identified by our audit.
Uncertain tax provisions, which was a key audit matter last year, is no longer included 
because of settlements agreed with tax authorities during the year. Otherwise, the key audit 
matters below are consistent with last year.

How our audit addressed the key audit matter
Refinery metal accounting (group and parent)
 
Refer to the Significant issues considered by the Audit Committee within the Audit 
Committee Report and note 1 and 36 to the financial statements. 
As part of its refining activities, the group processes a significant amount of metal on behalf 
of third parties, whereby the group must return pre-agreed recoverable quantities of 
refined metal to those parties at an agreed date. Any metal in excess of this pre-agreed 
quantity is retained by the group. As such, the group makes an estimate of how much 
metal it will recover as part of its refining operations. The majority of metal processed at 
refineries is owned by customers and is not held on the financial balance sheet of the 
group. As such, the group performs a metal balance sheet reconciliation to ensure 
quantities of precious metals held at year-end are appropriately understood, classified as 
either owned by Johnson Matthey or by the customer and reconciled to its financial 
position. This ensures that only the group-owned inventory is recorded on the balance 
sheet and that the price allocated to this owned inventory is at the lower of cost and net 
realisable value. 
During the refining process, there are a series of complex estimates including: 
i.	 Estimation of the level of metal contained in the carrier material entering the refining 
process, the refined metal that leaves the refining process and the residual metal in the 
refining process at year-end; 
ii.	 Estimates of the process losses of precious metals that may be lost during the refining 
and fabrication process and the adequacy of these provisions; 
iii.	Estimates of the metal in the refinery process as informed by refinery stocktakes and the 
subsequent sampling and assaying to assess the precious metal content in stocktake 
samples; and 
iv.	Estimates of the net realisable value of unhedged metal held at year-end. 
Each of these estimates impacts different areas of the audit. The refining process and its 
associated estimates are an area of focus for our audit due to the inherent complexity of 
the accounting and the amount of metal processed.
We evaluated the design and operation of key controls at the main refining locations over 
refinery stocktakes and metal assaying procedures. We tested that the metal balance sheet 
was prepared and reviewed on a monthly basis. We tested the classification of precious 
metals at year-end on the metal balance sheet to determine if metal was owned by the 
group or the customer.
Our procedures included sending confirmations to customers, and testing the balance of 
customer metal that was in the refining process, but not contractually due.
We assessed management’s policy for recognising stocktake gains and losses arising from 
stocktakes. We attended physical stock counts at sites where these stocktakes were 
performed. The purpose was to verify the existence of inventory and adherence to the 
group’s stocktake processes and to assess the reasonableness of stocktake gains and losses 
at these sites. 
We assessed the underlying controls that have been implemented by management to 
monitor potential inventory gains or losses through the refining process and stocktake 
results and to assess the likelihood and quantum of process losses (if any) of metal between 
the date of the stocktake and the year-end date. We assessed process loss provisions 
compared to historical metal gain revenue and refinery stocktake results. 
We tested that all unhedged metal was being held at the lower of cost and net realisable 
value, on an individual metal by metal methodology, with reference to external metal 
price data.
We considered the adequacy of the group’s disclosures about the degree of estimation 
involved in arriving at the value of metal inventory. 
Based on the procedures performed, we noted no material issues arising from our work.

Carrying value of goodwill (group and parent)
 
Refer to the Significant issues considered by the Audit Committee within the Audit 
Committee Report and notes 1, 5, 13, 36 and 38 to the financial statements. 
The group holds goodwill of £353 million (2023: £364 million) at 31 March 2024. Of this 
amount, £113 million (2023: £113 million) is held within the parent company. 
The group has significant goodwill arising from the acquisition of businesses and the 
carrying value is dependent on the financial performance of the cash generating unit 
(CGU) to which it relates. The two largest CGUs are Catalyst Technologies and Clean Air 
Heavy Duty Catalysts which account for £264m (2023: £268m) and £84m (2023: £87m) 
respectively of goodwill at 31 March 2024. The goodwill held in the parent company relates 
to the Catalyst Technologies CGU. 
The impairment assessments prepared by management reflect its best estimates of future 
cashflows. These estimates contain significant uncertainty and are inherently judgemental 
in nature, where changes in the key assumptions can result in materially different 
impairment charges or available headroom. As set out in note 1, management has 
considered the impacts of climate change in their models. This is therefore an area of focus 
in our audit procedures. 
Management’s assessment of the goodwill in the other CGUs concluded that no impairment 
was required. 
Management included disclosures to explain its key judgements and estimates as part of 
notes 1 and 5.
We obtained management’s value in use goodwill impairment models and agreed the 
forecast cash flows to board-approved budgets, assessed how these budgets are compiled, 
confirmed data accuracy and understood and evaluated key related judgements and estimates. 
We assessed management’s historical forecasting accuracy by comparing the prior year 
forecasts with actual results. This informed our independent sensitivity analysis. 
We performed work over each material CGU being the Catalyst Technologies and Clean Air 
Heavy Duty Catalysts CGUs. The nature and extent of work was commensurate with the 
level of headroom and sensitivity of the CGU to impairment. 
Our testing was focused on the key assumptions in the board-approved three year forecasts 
and we corroborated the assumptions to supporting evidence which included both internal 
and external sources of evidence. In addition, we assessed the appropriateness and impact 
of the specific growth assumptions applied by management for the period after the year 
three forecast but before a long term growth rate is applied (typically year ten). 
Management has included certain key assumptions relating to climate change. These 
include restricting the useful economic life applied in modelling Heavy Duty Catalysts to 
2040 (2023: 2040) and the application of a negative growth rate from 2033 (2023: 2033). 
Working with our valuation experts, we have considered external market outlooks and 
information on emission legislation to corroborate these assumptions. 
We engaged our valuations experts to assess the long term growth rate and discount  
rate for each CGU by comparison with third party information and past performance. 
Our procedures also included considering the overall level of risk in the future cash 
flow projections. 
We tested the mathematical integrity of the forecasts and of the value in use model, 
audited the allocation of central costs to the CGUs and agreed the carrying values in 
management’s impairment models to underlying accounting records. 
We assessed management’s sensitivity analysis and performed our own independent sensitivity 
analysis which was more severe than management’s to assess whether a reasonable 
downside change in the key assumptions could give rise to a material impairment.
We consider the disclosures with respect of goodwill, including the associated sensitivities, 
to be appropriate.
Based on the procedures performed, we noted no material issues arising from our work.

Claims, uncertainties and other provisions (group and parent)
 
Refer to the Significant issues considered by the Audit Committee and notes 1, 22, 32, 36 
and 47 to the financial statements. 
This risk covers warranty provisions, product liability issues and other litigation matters 
across the group. There is inherent judgement and estimation involved in determining 
when and how much to provide for claims and uncertainties. 
Due to the complex nature of the products offered by Johnson Matthey, the group at any 
point in time may be exposed to liability issues including claims for damages or 
compensation. The assumptions underpinning these claims and the identification of when 
such claims arise are inherently judgemental. Careful consideration needs to be given as to 
how the claim and any potential exposure are estimated and subsequently accounted for. 
The group is also involved in various legal proceedings, including actual or threatened 
litigation and regulatory investigations. The number and nature of claims vary from year to 
year; note 32 discloses the major matters in the year. The most significant is the contingent 
liability arising following the sale of the Health Business in May 2022.
The group discloses such risks as contingent liabilities where it is unable to make a reliable 
estimate of potential exposures or where it believes a material outflow is possible but not 
probable. If the group is unable to successfully defend against such claims, these risks could 
give rise to a future liability.
For litigation matters, we read the summary of major litigation matters provided by 
management and held discussions with group and sector level general counsel. For new 
matters with potential exposure above £1 million, we obtained and reviewed 
correspondence with external legal counsel, including any particulars of claim. 
We have circularised external legal counsel to independently assess legal exposures and the 
expected outcome for new and material cases across the group. 
We reviewed board minutes and made inquiries of management to address the  
risk of undisclosed claims and uncertainties. We performed audit procedures to identify  
all third party legal counsel used by management and as appropriate included them in 
our circularisation. 
We applied professional scepticism in auditing both the likely outcome and quantification 
of exposures, including performing audit procedures over claims management determined 
to be immaterial and being sceptical of where a constructive obligation existed but 
management considered a reliable estimate could not be made. As we deemed it to be 
necessary, we also instructed third party legal experts to support an independent 
assessment of possible outcomes of claims. 
Where settlements have occurred, we have agreed these to settlement agreements 
between the company and the claimant. 
We have assessed the level of provisioning and contingent liability disclosures, where 
relevant, in response to known claims. 
Based on the procedures performed, we noted no material issues arising from our work.

How we tailored the audit scope
We tailored the scope of our audit to ensure that we performed enough work to be able to 
give an opinion on the financial statements as a whole, taking into account the structure of 
the group and the company, the accounting processes and controls, and the industry in 
which they operate.
The group is structured across five sectors: Clean Air, PGM Services, Catalyst Technologies, 
Hydrogen Technologies and Value Businesses, as well as the central Corporate unit.
The financial statements are a consolidation of approximately 236 business units. We have 
identified each individual business unit, or a series of business units where they map to a 
single legal statutory entity, as a component. These components comprise the group’s 
operating businesses and holding companies across the five sectors and corporate.
Based on our risk and materiality assessments, we determined which components required 
an audit of their complete financial information having considered the relative significance 
of each entity to the group, locations with significant inherent risks and the overall coverage 
obtained over each material line item in the consolidated financial statements.
We identified 17 business units which, in our view, required an audit of their complete 
financial information, due to size or risk characteristics.
In addition to the business units in full scope, we performed specified procedures at 
15 business units covering revenue, trade and other receivables and deferred income, 
cash, inventory, metal inventory, accruals, fixed assets and depreciation, cost of sales and 
operating expenses and we tested manual journal entries. This ensured that appropriate 
audit procedures were performed to achieve sufficient coverage over these financial 
statement line items.
The total 32 in-scope business units are located in numerous countries around the world. 
We used local teams in these countries to perform the relevant audit procedures. Of these, 
five business units have been determined to be financially significant based on their 
contribution to the group. These financially significant component teams are located  
in the UK, North Macedonia and the United States.
The group consolidation, financial statement disclosures and corporate functions were 
audited by the group audit team. This included our work over the consolidation, litigation 
provisions, centrally recognised tax balances, goodwill, post-retirement benefits, earnings 
per share and treasury related balances. This scope of work, together with additional 
procedures performed at the group level, accounted for 84% of group revenue and 62% of 
group underlying profit before taxation from continuing operations. This provided the 
evidence we needed for our opinion on the consolidated financial statements taken as a 
whole. This was before considering the contribution to our audit evidence from performing 
audit work at the group level, including disaggregated analytical review procedures, which 
covers certain of the group’s smaller and lower risk components that were not directly 
included in our group audit scope. Our audit of the Parent Company Financial Statements 
was undertaken by the Group audit team and included substantive procedures over all 
material balances and transactions. 
The impact of climate risk on our audit
Climate change is expected to present both risks and opportunities for the group. As explained 
in the Sustainability section of the Strategic Report, the group has plans towards a Net Zero 
pathway by 2040. Management’s climate change initiatives and commitments will impact 
the group in a variety of ways. While the group has started to quantify some of the impacts 
that may arise on its net zero pathway, the future financial impacts are clearly uncertain 
given the medium to long term horizon. Disclosure of the impact of climate change risk 
based on management’s current assessment is incorporated in the Task Force on climate 
related financial disclosures (‘TCFD’) section of the Annual Report.
As part of our audit, we made enquiries of management to understand the extent of the 
potential impact of climate change on the group’s business and the financial statements, 
including reviewing management’s climate change risk assessment which was prepared with 
support from an external expert. Using our knowledge of the business, we challenged the 
completeness of management’s risk assessment. This included reading CDP submissions 
made by the Group and its competitors to ensure appropriate consistency with the 
judgements and disclosures reflected in the Financial Statements.
We assessed that the key areas in the financial statements which are more likely to be 
materially impacted by climate change are those areas that are based on future cash flows. 
As a result, we particularly considered how climate change risks and the impact of climate 
commitments made by the group would impact the assumptions made in the forecasts 
prepared by management that are used in the group’s impairment analysis (see also key 
audit matter on Carrying value of goodwill) and for going concern purposes. We challenged 
how management had considered longer term physical risks such as severe weather related 
impacts, and shorter-term transitional risks such as the introduction of carbon taxes. Our 
procedures did not identify any material impact on our audit for the year ended 31 March 
2024. We also checked the consistency of the disclosures in the TCFD section of the Annual 
Report with the relevant financial statement disclosures, including note 1 and the going 
concern section of the accounting policies, and with our understanding of the business and 
knowledge obtained in the audit.
We confirmed with management and the Audit Committee that the estimated financial 
impacts of climate change will be reassessed prospectively and our expectation is that 
climate change disclosures will evolve as the understanding of the actual and potential 
impacts on the group’s future operations is established with greater certainty.

Materiality
The scope of our audit was influenced by our application of materiality. We set certain quantitative thresholds for materiality. These, together with qualitative considerations, helped us to 
determine the scope of our audit and the nature, timing and extent of our audit procedures on the individual financial statement line items and disclosures and in evaluating the effect of 
misstatements, both individually and in aggregate on the financial statements as a whole.
Based on our professional judgement, we determined materiality for the financial statements as a whole as follows:
 
Financial statements – group
Financial statements – company
Overall materiality
£20.1 million (2023: £21.1 million).
£70.6 million (2023: £60 million).
How we determined it
approximately 5% of the three year profit before tax from continuing 
operations, adjusted for loss on disposal of businesses, gains and losses on 
significant legal proceedings, major impairment, amortisation of acquired 
intangibles and restructuring charges (“underlying profit before tax”)
approximately 1% of total assets. However, materiality is capped at £19.5 million 
(2023: £20 million) for the purpose of the audit of the consolidated financial 
statements, being the maximum allocation of group materiality to a component
Rationale for 
benchmark applied
Underlying profit before tax from continuing operations is used as  
the materiality benchmark. Management uses this measure as it believes 
that it reflects the underlying performance of the group and this is how 
the directors and key management personnel are measured on 
their performance.
We considered total assets to be an appropriate benchmark for the parent 
company given that, while it does include trading businesses, it is the ultimate 
holding company, incurs corporate costs and enters into financing on behalf of the 
group. The parent company is also a component of the group audit.
The materiality level was capped at £19.5 million given overall group materiality 
for the purposes of the audit of the consolidated financial statements, being the 
maximum allocation of group materiality to a component.
For each component in the scope of our group audit, we allocated a materiality that is less than our overall group materiality. The range of materiality allocated across components was 
between £1.4 million and £19.5 million. Certain components were audited to a local statutory audit materiality that was also less than our overall group materiality.
We use performance materiality to reduce to an appropriately low level the probability that the aggregate of uncorrected and undetected misstatements exceeds overall materiality. 
Specifically, we use performance materiality in determining the scope of our audit and the nature and extent of our testing of account balances, classes of transactions and disclosures, for 
example in determining sample sizes. Our performance materiality was 75% (2023: 75%) of overall materiality, amounting to £15.1 million (2023: £15.8 million) for the group financial 
statements and £14.6 million (2023: £15 million) for the company financial statements.
In determining the performance materiality, we considered a number of factors – the history of misstatements, risk assessment and aggregation risk and the effectiveness of controls – and 
concluded that an amount at the upper end of our normal range was appropriate.
We agreed with the Audit Committee that we would report to them misstatements identified during our audit above £1 million (group audit) (2023: £1 million) and £1 million (company audit) 
(2023: £1 million) as well as misstatements below those amounts that, in our view, warranted reporting for qualitative reasons.

Conclusions relating to going concern
Our evaluation of the directors’ assessment of the group’s and the company’s ability to 
continue to adopt the going concern basis of accounting included:
•	 Evaluation of management’s base case and downside case scenarios, understanding and 
evaluating the key assumptions, including assumptions related to inflation and other 
macro-economic factors;
•	 Validation that the cash flow forecasts used to support management’s impairment, going 
concern and viability assessments were consistent;
•	 Assessment of the historical accuracy and reasonableness of management’s forecasting;
•	 Consideration of the group’s available financing and debt maturity profile;
•	 Testing of the mathematical integrity of management’s liquidity headroom, covenant 
compliance, sensitivity analysis and stress testing calculations;
•	 Assessment of the reasonableness of management’s planned or potential mitigating 
actions; and
•	 Reviewing the related disclosures in the Annual Report.
Based on the work we have performed, we have not identified any material uncertainties 
relating to events or conditions that, individually or collectively, may cast significant doubt 
on the group’s and the company’s ability to continue as a going concern for a period of at 
least twelve months from when the financial statements are authorised for issue.
In auditing the financial statements, we have concluded that the directors’ use of the going 
concern basis of accounting in the preparation of the financial statements is appropriate.
However, because not all future events or conditions can be predicted, this conclusion is not 
a guarantee as to the group’s and the company’s ability to continue as a going concern.
In relation to the directors’ reporting on how they have applied the UK Corporate Governance 
Code, we have nothing material to add or draw attention to in relation to the directors’ 
statement in the financial statements about whether the directors considered it appropriate 
to adopt the going concern basis of accounting.
Our responsibilities and the responsibilities of the directors with respect to going concern are 
described in the relevant sections of this report.
Reporting on other information
The other information comprises all of the information in the Annual Report other than the 
financial statements and our auditors’ report thereon. The directors are responsible for the 
other information. Our opinion on the financial statements does not cover the other 
information and, accordingly, we do not express an audit opinion or, except to the extent 
otherwise explicitly stated in this report, any form of assurance thereon.
In connection with our audit of the financial statements, our responsibility is to read the 
other information and, in doing so, consider whether the other information is materially 
inconsistent with the financial statements or our knowledge obtained in the audit, or 
otherwise appears to be materially misstated. If we identify an apparent material 
inconsistency or material misstatement, we are required to perform procedures to conclude 
whether there is a material misstatement of the financial statements or a material 
misstatement of the other information. If, based on the work we have performed, we 
conclude that there is a material misstatement of this other information, we are required to 
report that fact. We have nothing to report based on these responsibilities.
With respect to the Strategic report and Directors’ Report, we also considered whether the 
disclosures required by the UK Companies Act 2006 have been included.
Based on our work undertaken in the course of the audit, the Companies Act 2006 requires 
us also to report certain opinions and matters as described below.
Strategic report and Directors’ Report
In our opinion, based on the work undertaken in the course of the audit, the information 
given in the Strategic report and Directors’ Report for the year ended 31 March 2024 is 
consistent with the financial statements and has been prepared in accordance with 
applicable legal requirements.
In light of the knowledge and understanding of the group and company and their 
environment obtained in the course of the audit, we did not identify any material 
misstatements in the Strategic report and Directors’ Report.
Directors’ Remuneration
In our opinion, the part of the Annual Report on Remuneration to be audited has been 
properly prepared in accordance with the Companies Act 2006.

Corporate governance statement
The Listing Rules require us to review the directors’ statements in relation to going concern, 
longer-term viability and that part of the corporate governance statement relating to the 
company’s compliance with the provisions of the UK Corporate Governance Code specified for 
our review. Our additional responsibilities with respect to the corporate governance statement 
as other information are described in the Reporting on other information section of this report.
Based on the work undertaken as part of our audit, we have concluded that each of the 
following elements of the corporate governance statement is materially consistent with the 
financial statements and our knowledge obtained during the audit, and we have nothing 
material to add or draw attention to in relation to:
•	 The directors’ confirmation that they have carried out a robust assessment of the emerging 
and principal risks;
•	 The disclosures in the Annual Report that describe those principal risks, what procedures 
are in place to identify emerging risks and an explanation of how these are being managed 
or mitigated;
•	 The directors’ statement in the financial statements about whether they considered it 
appropriate to adopt the going concern basis of accounting in preparing them, and their 
identification of any material uncertainties to the group’s and company’s ability to 
continue to do so over a period of at least twelve months from the date of approval of the 
financial statements;
•	 The directors’ explanation as to their assessment of the group’s and company’s prospects, 
the period this assessment covers and why the period is appropriate; and
•	 The directors’ statement as to whether they have a reasonable expectation that the 
company will be able to continue in operation and meet its liabilities as they fall due over 
the period of its assessment, including any related disclosures drawing attention to any 
necessary qualifications or assumptions.
Our review of the directors’ statement regarding the longer-term viability of the group and 
company was substantially less in scope than an audit and only consisted of making inquiries 
and considering the directors’ process supporting their statement; checking that the 
statement is in alignment with the relevant provisions of the UK Corporate Governance Code; 
and considering whether the statement is consistent with the financial statements and our 
knowledge and understanding of the group and company and their environment obtained in 
the course of the audit.
In addition, based on the work undertaken as part of our audit, we have concluded that each 
of the following elements of the corporate governance statement is materially consistent 
with the financial statements and our knowledge obtained during the audit:
•	 The directors’ statement that they consider the Annual Report, taken as a whole, is fair, 
balanced and understandable, and provides the information necessary for the members to 
assess the group’s and company’s position, performance, business model and strategy;
•	 The section of the Annual Report that describes the review of effectiveness of risk 
management and internal control systems; and
•	 The section of the Annual Report describing the work of the Audit Committee.
We have nothing to report in respect of our responsibility to report when the directors’ statement 
relating to the company’s compliance with the Code does not properly disclose a departure from a 
relevant provision of the Code specified under the Listing Rules for review by the auditors.
Responsibilities for the financial statements and the audit
Responsibilities of the directors for the financial statements
As explained more fully in the Statement of directors’ responsibilities in respect of the Annual 
Report and Accounts, the directors are responsible for the preparation of the financial 
statements in accordance with the applicable framework and for being satisfied that they 
give a true and fair view. The directors are also responsible for such internal control as they 
determine is necessary to enable the preparation of financial statements that are free from 
material misstatement, whether due to fraud or error.
In preparing the financial statements, the directors are responsible for assessing the group’s 
and the company’s ability to continue as a going concern, disclosing, as applicable, matters 
related to going concern and using the going concern basis of accounting unless the 
directors either intend to liquidate the group or the company or to cease operations, or have 
no realistic alternative but to do so.
Auditors’ responsibilities for the audit of the financial statements
Our objectives are to obtain reasonable assurance about whether the financial statements as a 
whole are free from material misstatement, whether due to fraud or error, and to issue an 
auditors’ report that includes our opinion. Reasonable assurance is a high level of assurance, 
but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect 
a material misstatement when it exists. Misstatements can arise from fraud or error and are 
considered material if, individually or in the aggregate, they could reasonably be expected to 
influence the economic decisions of users taken on the basis of these financial statements.
Irregularities, including fraud, are instances of non-compliance with laws and regulations. 
We design procedures in line with our responsibilities, outlined above, to detect material 
misstatements in respect of irregularities, including fraud. The extent to which our 
procedures are capable of detecting irregularities, including fraud, is detailed below.
Based on our understanding of the group and industry, we identified that the principal risks 
of non-compliance with laws and regulations related to environmental legislation, health 
and safety regulations (EHS) and anti bribery and corruption laws, and we considered the 
extent to which non-compliance might have a material effect on the financial statements. 
We also considered those laws and regulations that have a direct impact on the financial 
statements such as tax legislation and the Companies Act 2006. We evaluated 
management’s incentives and opportunities for fraudulent manipulation of the financial 
statements (including the risk of override of controls), and determined that the principal 
risks were related to posting inappropriate journal entries and management bias in making 
accounting estimates and judgements. The group engagement team shared this risk 
assessment with the component auditors so that they could include appropriate audit 
procedures in response to such risks in their work.

Other information

Audit procedures performed by the group engagement team and/or component 
auditors included:
•	 Discussions with management, internal audit and the group’s legal advisors, and the head 
of ethics and compliance including consideration of known or suspected instances of 
non-compliance with laws and regulations and fraud;
•	 Reading the minutes of board meetings and the Ethics Committee, and assessment of 
“SpeakUp” matters through the ethics reporting line and the results of management’s 
investigation into these matters;
•	 Reviewing financial statement disclosures to supporting documentation to assess 
compliance with applicable laws and regulations;
•	 Challenging management’s significant judgements and estimates in particular those 
relating to the carrying value of goodwill, post-employment benefits, refining processes 
and stocktakes, metal accounting and provisions and contingent liabilities;
•	 Identifying and testing manual journal entries, in particular any journal entries posted with 
unusual account combinations, and all material consolidation journals;
•	 Incorporating unpredictable procedures into our audit approach including varying the 
timing and nature of testing performed; and
•	 Considering the outcome of key transactions in the year and assessing the appropriateness 
of related accounting and disclosure within the financial statements.
There are inherent limitations in the audit procedures described above. We are less likely to 
become aware of instances of non-compliance with laws and regulations that are not closely 
related to events and transactions reflected in the financial statements. Also, the risk of not 
detecting a material misstatement due to fraud is higher than the risk of not detecting one 
resulting from error, as fraud may involve deliberate concealment by, for example, forgery or 
intentional misrepresentations, or through collusion.
Our audit testing might include testing complete populations of certain transactions and 
balances, possibly using data auditing techniques. However, it typically involves selecting a 
limited number of items for testing, rather than testing complete populations. We will often 
seek to target particular items for testing based on their size or risk characteristics. In other 
cases, we will use audit sampling to enable us to draw a conclusion about the population 
from which the sample is selected.
A further description of our responsibilities for the audit of the financial statements is located 
on the FRC’s website at: www.frc.org.uk/auditorsresponsibilities. This description forms part 
of our auditors’ report.
Use of this report
This report, including the opinions, has been prepared for and only for the company’s 
members as a body in accordance with Chapter 3 of Part 16 of the Companies Act 2006 and 
for no other purpose. We do not, in giving these opinions, accept or assume responsibility for 
any other purpose or to any other person to whom this report is shown or into whose hands 
it may come save where expressly agreed by our prior consent in writing.
Other required reporting
Companies Act 2006 exception reporting
Under the Companies Act 2006 we are required to report to you if, in our opinion:
•	 we have not obtained all the information and explanations we require for our audit; or
•	 adequate accounting records have not been kept by the company, or returns adequate for 
our audit have not been received from branches not visited by us; or
•	 certain disclosures of directors’ remuneration specified by law are not made; or
•	 the company financial statements and the part of the Annual Report on Remuneration to 
be audited are not in agreement with the accounting records and returns.
We have no exceptions to report arising from this responsibility.
Appointment
Following the recommendation of the Audit Committee, we were appointed by the members 
on 18 July 2018 to audit the financial statements for the year ended 31 March 2019 and 
subsequent financial periods. The period of total uninterrupted engagement is six years, 
covering the years ended 31 March 2019 to 31 March 2024.
Other matter
The company is required by the Financial Conduct Authority Disclosure Guidance and 
Transparency Rules to include these financial statements in an annual financial report 
prepared under the structured digital format required by DTR 4.1.15R – 4.1.18R and filed on 
the National Storage Mechanism of the Financial Conduct Authority. This auditors’ report 
provides no assurance over whether the structured digital format annual financial report has 
been prepared in accordance with those requirements.

Notes on the Accounts  
for the year ended 31st March 2024 
1 
Accounting policies  
The Company and the Group 
Johnson Matthey plc (the ‘Company’) is a public company limited by shares incorporated under the 
Companies Act 2006 and domiciled in England in the United Kingdom. The consolidated accounts 
of the company for the year ended 31st March 2024 consist of the audited consolidation of the 
accounts of the Company and its subsidiaries (together referred to as the ‘Group’), together with 
the employee share ownership trust and the group's interest in joint ventures and associates. 
Basis of accounting and preparation – group 
The financial statements of the group have been prepared in accordance with UK-adopted 
International Accounting Standards and with the requirements of the Companies Act 2006 as 
applicable to companies reporting under those standards. 
The accounts are prepared on the historical cost basis, except for certain assets and liabilities 
which are measured at fair value as explained below. 
The group accounts comprise the accounts of the parent company and its subsidiaries, 
including the employee share ownership trust, and include the group's interest in joint ventures 
and associates. Entities the group controls are accounted for as subsidiaries. Entities that are 
joint ventures or associates are accounted for using the equity method of accounting. 
Transactions and balances between group companies are eliminated. Profit recognised on 
transactions between group companies is eliminated on consolidation. 
The results of businesses acquired or disposed of in the year are consolidated from or up to the 
effective date of acquisition or disposal, respectively. The net assets of businesses acquired are 
recognised in the consolidated accounts at their fair values at the date of acquisition. 
Going concern 
The directors have reviewed a range of scenario forecasts for the group and have reasonable 
expectation that there are no material uncertainties that cast doubt about the group’s ability to 
continue operating for at least twelve months from the date of approving these annual accounts. 
As at 31st March 2024, the group maintains a strong balance sheet with around £1.5 billion  
of available cash and undrawn committed facilities. Free cash flow was strong in the year  
at £189 million and net debt reduced by £72 million. Net debt at 31st March 2024 was 
£951 million at 1.6 times net debt (including post tax pension deficits) to underlying EBITDA 
which was at the lower end of our target range. 
Although impacted by the significant headwinds faced in the current macroeconomic 
environment such as low metal prices and continued soft economic outlook across major 
economies, the group’s performance during the period was resilient, both in terms of underlying 
operating profit and cash flow. For the purposes of assessing going concern, we have revisited our 
financial projections using the latest budget for our base case scenario. The base case scenario was 
stress tested to a severe-but-plausible downside case which reflects severe recession scenarios. 
The severe-but-plausible case for Clean Air modelled scenarios assuming a smaller light duty 
vehicle market from reduced vehicle production and/or market consumer demand disruption or 
greater share of zero emission vehicles in market, assumed to result in a 10% drop in sales. For 
PGMS and Catalyst Technologies, it also assumed a reduction in sales and associated operating 
profit based on adverse scenarios using external and internal market insights. 
Additionally, as part of viability testing, the group considered scenarios including the impact 
from metal price volatility, delays in capital projects and delivery of cost transformation savings, 
and slow down of operations in China. Whilst the combined impact would reduce profitability 
and EBITDA against our latest budget, our balance sheet remains strong with ample working 
capital and Net Debt/EBITDA ratios. 
The group has a robust funding position comprising a range of long-term debt and a £1 billion 
five year committed revolving credit facility maturing in March 2027 which was entirely 
undrawn at 31st March 2024. There was £334 million of cash held in money market funds and 
£208 million of other cash and bank deposits. Of the existing loans, £271 million of term debt 
and £40 million of other bank loans mature in the period to June 2025. Currently, the group is 
in the process of refinancing around £310m of term debt with a US Private Placement issuance. 
We assume no refinancing of this debt in our going concern modelling. As a long time, highly 
rated issuer in the US private placement market, the group expects to be able to access 
additional funding in its existing markets if required but the going concern conclusion is not 
dependent on such access as the company has sufficient financing and liquidity to fund its 
obligations in the base and severe-but-plausible scenarios. The group also has a number of 
additional sources of funding available including uncommitted metal lease facilities that 
support precious metal funding. Whilst we would fully expect to be able to utilise the metal 
lease facilities, they are excluded from our going concern modelling. 
Conclusion 
Under all scenarios above, the group has sufficient headroom against committed facilities and 
key financial covenants are not in breach during the going concern period. To give further 
assurance on liquidity, we have also undertaken a reverse stress test to identify what additional 
or alternative scenarios and circumstances would threaten our current financing arrangements. 
This shows that we have headroom against either a further decline in profitability well beyond 
the severe-but-plausible scenario, or a significant increase in borrowings, or a significant 
increase in interest charges. Furthermore, the group has other mitigating actions available 
which it could utilise to protect headroom including retaining the full expected proceeds from 
divestment of Medical Device Components, reducing capital expenditure, renegotiating 
payment terms or reducing future dividends distributions.

Accounting policies (continued) 
The directors are therefore of the opinion that the group has adequate resources to fund its 
operations for the period of at least twelve months following the date of these financial 
statements and there are no material uncertainties relating to going concern so determine that 
it is appropriate to prepare the accounts on a going concern basis. 
Material accounting policies 
The group’s and parent company’s accounting policies have been applied consistently during 
the current and prior year, other than where new policies have been adopted (see below). 
The group’s and parent company’s material accounting policies are as follows: 
Foreign currencies 
Foreign currency transactions are recorded in the functional currency of the relevant subsidiary, 
joint venture, associate or branch at the exchange rate at the date of the transaction. Foreign 
currency monetary assets and liabilities are retranslated into the relevant functional currency at 
the exchange rate at the balance sheet date. 
Income statements and cash flows of overseas subsidiaries, joint ventures, associates and 
branches are translated into sterling at the average rates for the year. Balance sheets of overseas 
subsidiaries, joint ventures, associates and branches, including any fair value adjustments and 
related goodwill, are translated into sterling at the exchange rates at the balance sheet date. 
Exchange differences arising on the translation of the net investment in overseas subsidiaries, 
joint ventures, associates and branches, less exchange differences arising on related foreign 
currency financial instruments which hedge the group’s net investment in these operations, 
are taken to other comprehensive income. On disposal of the net investment, the cumulative 
exchange difference is reclassified from equity to operating profit.  
Other exchange differences are recognised in operating profit. 
Revenue 
Revenue represents income derived from contracts for the provision of goods and services by 
the parent company and its subsidiaries to customers in exchange for consideration in the 
ordinary course of the group’s activities. 
Performance obligations  
Upon approval by the parties to a contract, the contract is assessed to identify each promise to 
transfer either a distinct good or service or a series of distinct goods or services that are 
substantially the same and have the same pattern of transfer to the customer. Goods and 
services are distinct and accounted for as separate performance obligations in the contract if the 
customer can benefit from them either on their own or together with other resources that are 
readily available to the customer and they are separately identifiable in the contract. 
The group typically sells licences to its intellectual property together with other goods and services 
and, since these licences are not generally distinct in the context of the contract, revenue recognition 
is considered at the level of the performance obligation of which the licence forms part. Revenue in 
respect of performance obligations containing bundles of goods and services in which a licence with a 
sales or usage-based royalty is the predominant item is recognised when sales or usage occur. 
Transaction price 
At the start of the contract, the total transaction price is estimated as the amount of 
consideration to which the group expects to be entitled in exchange for transferring the 
promised goods and services to the customer, excluding sales taxes. Variable consideration, 
such as trade discounts, is included based on the expected value or most likely amount only to 
the extent that it is highly probable that there will not be a reversal in the amount of cumulative 
revenue recognised. The transaction price does not include estimates of consideration resulting 
from contract modifications until they have been approved by the parties to the contract. The 
total transaction price is allocated to the performance obligations identified in the contract in 
proportion to their relative stand-alone selling prices. Many of the group's and parent company’s 
products and services are bespoke in nature and, therefore, stand-alone selling prices are 
estimated based on cost plus margin or by reference to market data for similar products 
and services. 
Revenue recognition 
Revenue is recognised as performance obligations are satisfied as control of the goods and 
services is transferred to the customer. 
For each performance obligation within a contract, the group and parent company determine 
whether it is satisfied over time or at a point in time. Performance obligations are satisfied over 
time if one of the following criteria is satisfied: 
• the customer simultaneously receives and consumes the benefits provided by the group’s and 
parent company’s performance as they perform; 
• the group’s and parent company’s performance creates or enhances an asset that the 
customer controls as the asset is created or enhanced; or 
• the group’s and parent company’s performance does not create an asset with an alternative 
use to the group and parent company and they have an enforceable right to payment for 
performance completed to date. 
 For more detail of our revenue recognition policy see note 3. 
In the event that the group and parent company enter into bill-and-hold transactions at the 
specific request of customers, revenue is recognised when the goods are ready for transfer to 
the customer and when the group and parent company are no longer capable of directing those 
goods to another use.  
Revenue includes sales of precious metal to customers and the precious metal content of 
products sold to customers. 
Linked contracts under which the group and parent company sell or buy precious metal and 
commit to repurchase or sell the metal in the future are accounted for as finance transactions 
and no revenue is recognised in respect of the sale leg.

1 
Accounting policies (continued) 
No revenue is recognised by the group or parent company in respect of non-monetary exchanges 
of precious metal on the basis that the counterparties are in the same line of business. 
Consideration payable to customers 
Consideration payable to customers in advance of the recognition of revenue in respect of the 
goods and services to which it relates is capitalised and recognised as a deduction to the 
revenue recognised upon transfer of the goods and services to the customer.  
Costs to fulfil a contract 
Contract fulfilment costs in respect of over time contracts are expensed as incurred. Contract 
fulfilment costs in respect of point in time contracts are accounted for under IAS 2, Inventories. 
Contract receivables 
Contract receivables represent amounts for which the group and parent company have a conditional 
right to consideration in respect of unbilled revenue recognised at the balance sheet date. 
Contract liabilities 
Contract liabilities represent the obligation to transfer goods or services to a customer for which 
consideration has been received, or consideration is due, from the customer. 
Finance costs and investment income 
Finance costs that are directly attributable to the construction of an asset that necessarily takes 
a substantial period of time to get ready for its intended use are capitalised as part of the cost of 
that asset. Other finance costs and finance income are recognised in the income statement in 
the year incurred. Finance costs and finance income include the forward point movements 
from FX Swap contracts (i.e. the interest rate differential between currencies specified in a FX 
Swap contract). Other finance costs and finance income are recognised in the income 
statement in the year incurred. 
Research and development 
Research expenditure is charged to the income statement in the year incurred. Development 
expenditure is charged to the income statement in the year incurred unless it meets the 
recognition criteria for capitalisation. When the recognition criteria have been met, any further 
development expenditure is capitalised as an intangible asset. 
Property, plant and equipment 
Property, plant and equipment is stated at cost less accumulated depreciation and any 
provisions for impairment. Depreciation is provided at rates calculated to write-off the cost less 
estimated residual value of each asset over its useful life and is recognised within administrative 
expenses. Certain buildings and plant and equipment are depreciated using the units of 
production method as this more closely reflects their expected consumption. All other assets are 
depreciated using the straight-line method. The useful lives vary according to the class of the 
asset, but are typically: 
• buildings – not exceeding 30 years; and 
• plant and machinery – 4 to 10 years. 
• land is not depreciated. 
The expected lives of property, plant and equipment tends to be short to medium term, as such 
the physical risk posed by climate change in the long term is low. 
Impairment 
The group and parent company reviews the carrying amounts of its non-financial assets 
regularly to determine whether there is any indication of impairment. Goodwill is tested for 
impairment annually or more frequently if there are indications that goodwill might be 
impaired. If any such indication of impairment exists, the recoverable amount of the non-
financial asset is estimated in order to determine the extent of any impairment loss. Where the 
asset does not generate cash flows that are independent from other assets, the group estimates 
the recoverable amount of the cash-generating unit (CGU) to which the asset belongs. 
Recoverable amount is the higher of fair value less costs to sell and value-in-use. In estimating 
value-in-use, the estimated future cash flows are discounted to their present value using a pre-
tax discount rate that reflects current market assessments of the time value of money and the 
risks specific to the asset (or CGU) for which the estimates of future cash flows have not 
been adjusted.  
An impairment loss is recognised as an expense immediately whenever the carrying amount of 
a non-financial asset or the CGU to which it belongs exceeds its recoverable amount. 
Impairment losses for goodwill are not reversable in subsequent reporting periods. Where an 
impairment loss subsequently reverses for a finite lived non-financial asset, the carrying amount 
of the asset (or CGU) is increased to the revised estimate of its recoverable amount, not to 
exceed the carrying amount that would have been determined had no impairment loss been 
recognised for the asset (or CGU) in prior years. A reversal of an impairment loss is recognised as 
income when identified. 
Goodwill and other intangible assets 
Goodwill arises on the acquisition of a business when the fair value of the consideration exceeds 
the fair value attributed to the net assets acquired (including contingent liabilities). It is subject 
to annual impairment reviews. Acquisition-related costs are charged to the income statement 
as incurred. The group and parent company have taken advantage of the exemption allowed 
under IFRS 1 and, therefore, goodwill arising on acquisitions made before 1st April 2004 is 
included at the carrying amount at that date less any subsequent impairments. 
Other intangible assets are stated at cost less accumulated amortisation and any provisions for 
impairment. Customer contracts are amortised when the relevant income stream occurs. 
All other intangible assets are amortised by using the straight-line method over the useful lives 
from the time they are first available for use. Amortisation is recognised within administrative 
expenses. The estimated useful lives vary according to the specific asset, but are typically: 
• customer contracts and relationships – 1 to 15 years; 
• capitalised computer software – 3 to 8 years; 
• patents, trademarks and licences – 3 to 20 years, for perpetual software licences the 
estimated useful is 4 to 7 years; 
• acquired research and technology – 4 to 10 years; and 
• capitalised development currently being amortised – 3 to 8 years. 
Intangible assets which are not yet being amortised are subject to annual impairment reviews.

Accounting policies (continued) 
Investments in associates 
Associates are entities over which the group exercises significant influence when it has the 
power to participate in the financial and operating policy decisions of the entity but it does not 
have the power to control or jointly control the entity. 
Investments in associates are accounted for using the equity method of accounting and are 
initially recognised at cost. Thereafter the investments are adjusted to recognise the group’s 
share of the post-acquisition profits or losses after tax of the investee in the income statement, 
and the group’s share of movements in other comprehensive income of the investee in other 
comprehensive income. Dividends received or receivable from associates are recognised as a 
reduction in the carrying amount of the investment. The carrying value of the investments are 
reviewed for impairment triggers on a regular basis.  
Where the group’s share of losses in an equity-accounted investment equals or exceeds its 
interest in the entity, the group does not recognise further losses unless it has incurred 
obligations to do so.  
Unrealised gains and losses on transactions between the group and its associates are eliminated 
to the extent of the group’s interest in these associates. 
Leases  
Leases are recognised as a right-of-use asset, together with a corresponding lease liability, at the 
date at which the leased asset is available for use.  
The right-of-use asset is initially measured at cost, which comprises the initial value of the lease 
liability, lease payments made (net of any incentives received from the lessor) before the 
commencement of the lease, initial direct costs and restoration costs. The right-of-use asset is 
depreciated on a straight-line basis over the shorter of the asset’s useful life and the lease term 
in operating profit.  
The lease liability is initially measured as the present value of future lease payments discounted 
using the interest rate implicit in the lease or, where this rate is not determinable, the group’s 
incremental borrowing rate, which is the interest rate the group would have to pay to borrow 
the amount necessary to obtain an asset of similar value in a similar economic environment 
with similar terms and conditions. Interest is charged to finance costs at a constant rate of 
interest on the outstanding lease liability over the lease term.  
Payments in respect of short-term leases, low-value leases and precious metal leases are 
charged to the income statement on a straight-line basis over the lease term in operating profit. 
The group leases precious metals to fund temporary peaks in metal requirements provided 
market conditions allow. These leases are from banks for specified periods (less than 12 
months) and the group pays a fee which is expensed on a straight-line basis over the lease term 
in finance costs. The group holds sufficient precious metal inventories to meet all the 
obligations under these lease arrangements as they fall due. Precious metal leases do not fall 
under the scope of IFRS 16. 
Inventories 
Precious metal 
Inventories of gold, silver and platinum group metals are valued according to the source from 
which the metal is obtained. Metal which has been purchased and committed to future sales to 
customers is valued at the price at which it is contractually committed, adjusted for unexpired 
contango and backwardation. Other precious metal inventories owned by the group, which are 
unhedged, are valued at the lower of cost and net realisable value using the weighted average 
cost formula. 
Other 
Non-precious metal inventories are valued at the lower of cost, including attributable 
overheads, and net realisable value. Except where costs are specifically identified, the first-in, 
first-out cost formula is used to value inventories. 
Cash and cash equivalents 
Cash and deposits comprise cash at bank and in hand and short-term deposits with a maturity 
date of three months or less from the date of acquisition. Money market funds comprise 
investments in funds that are subject to an insignificant risk of changes in fair value. The group 
and parent company routinely use short-term bank overdraft facilities, which are repayable on 
demand, as an integral part of their cash management policies and, therefore, cash and cash 
equivalents include cash and deposits, money market funds and bank overdrafts. Offset 
arrangements across group businesses have been applied to arrive at the net cash and 
overdraft figures. 
Financial instruments  
Investments and other financial assets 
The group and parent company classify their financial assets in the following 
measurement categories: 
• those measured at fair value either through other comprehensive income or through profit or 
loss; and 
• those measured at amortised cost. 
At initial recognition, the group and parent company measure financial assets at fair value plus, 
in the case of financial assets not measured at fair value through profit or loss, transaction costs 
that are directly attributable to their acquisition. 
The group and parent company subsequently measure equity investments at fair value and 
have elected to present fair value gains and losses on equity investments in other 
comprehensive income. There is, therefore, no subsequent reclassification of cumulative fair 
value gains and losses to profit or loss following disposal of the investments.

Accounting policies (continued) 
The group and parent company subsequently measure trade and other receivables and  
contract receivables at amortised cost, with the exception of trade receivables that have been 
designated as at fair value through other comprehensive income because the group has certain 
operations with business models to hold trade receivables for collection or sale. All other 
financial assets, including short-term receivables, are measured at amortised cost less any 
impairment provision. 
For the impairment of trade and contract receivables, the group and parent company apply the 
simplified approach permitted by IFRS 9, Financial Instruments, which requires expected 
lifetime losses to be recognised from initial recognition. 
Derivative financial instruments 
The group and parent company use derivative financial instruments, in particular forward 
currency contracts, currency swaps, interest rate swaps and commodity derivatives to manage 
the financial risks associated with their underlying business activities and the financing of those 
activities. The group and parent company do not undertake any speculative trading activity in 
derivative financial instruments. 
Derivative financial instruments are measured at their fair value. Derivative financial 
instruments may be designated at inception as fair value hedges, cash flow hedges or net 
investment hedges if appropriate. For currency swaps designated as instruments in cash flow or 
net investment hedging relationships, the impact from currency basis spreads is included in the 
hedge relationship and may be a source of ineffectiveness recognised in the income statement.  
Derivative financial instruments which are not designated as hedging instruments are classified 
as at fair value through profit or loss, but are used to manage financial risk. Changes in the fair 
value of any derivative financial instruments that are not designated as, or are not determined 
to be, effective hedges are recognised immediately in the income statement. The vast majority 
of forward precious metal price contracts are entered into and held for the receipt or delivery of 
precious metal and, therefore, are not recorded at fair value. 
Cash flow hedges 
Changes in the fair value of derivative financial instruments designated as cash flow hedges are 
recognised in other comprehensive income to the extent that the hedges are effective. 
Ineffective portions are recognised in the income statement immediately. If the hedged item 
results in the recognition of a non-financial asset or liability, the amount previously recognised 
in other comprehensive income is transferred out of equity and included in the initial carrying 
amount of the asset or liability. Otherwise, the amount previously recognised in other 
comprehensive income is transferred to the income statement in the same period that the 
hedged item is recognised in the income statement. If the hedging instrument expires or is sold, 
terminated or exercised or the hedge no longer meets the criteria for hedge accounting, 
amounts previously recognised in other comprehensive income remain in equity until the 
forecast transaction occurs. If a forecast transaction is no longer expected to occur, the amounts 
previously recognised in other comprehensive income are transferred to the income statement. 
If a forward precious metal price contract will be settled net in cash, it is designated and 
accounted for as a cash flow hedge. 
Fair value hedges 
Changes in the fair value of derivative financial instruments designated as fair value hedges are 
recognised in the income statement, together with the related changes in the fair value of the 
hedged asset or liability. Fair value hedge accounting is discontinued if the hedging instrument 
expires or is sold, terminated or exercised or the hedge no longer meets the criteria for 
hedge accounting. 
Net investment hedges 
For hedges of net investments in foreign operations, the effective portion of the gain or loss on 
the hedging instrument is recognised in other comprehensive income, while the ineffective 
portion is recognised in the income statement. Amounts taken to other comprehensive income 
are reclassified from equity to the income statement when the foreign operations are sold 
or liquidated. 
Financial liabilities 
Borrowings are measured at amortised cost. Those borrowings designated as being in fair value 
hedge relationships are remeasured for the fair value changes in respect of the hedged risk with 
these changes recognised in the income statement. All other financial liabilities, including 
short-term payables, are measured at amortised cost. 
Precious metal sale and repurchase agreements 
The group and parent company undertake linked contracts to sell or buy precious metal and 
commit to repurchase or sell the metal in the future. An asset representing the metal which the 
group and parent company have committed to sell or a liability representing the obligation to 
repurchase the metal are recognised in trade and other receivables or trade and other 
payables, respectively. 
Taxation 
Current and deferred tax are recognised in the income statement, except when they relate to 
items recognised directly in equity, in which case the related tax is also recognised in equity. 
Current tax is the amount of income tax expected to be paid in respect of taxable profits using 
the tax rates that have been enacted or substantively enacted at the balance sheet date. 
Deferred tax is provided in full, using the liability method, on temporary differences arising 
between the tax bases of assets and liabilities and their carrying amounts in the balance sheet. It 
is provided using the tax rates that are expected to apply in the period when the asset or liability 
is settled, based on tax rates that have been enacted or substantively enacted at the balance 
sheet date. 
Deferred tax assets are recognised to the extent that it is probable that future taxable profits will 
be available against which the temporary differences can be utilised. No deferred tax asset or 
liability is recognised in respect of temporary differences associated with investments in 
subsidiaries and branches where the group is able to control the timing of the reversal of the 
temporary difference and it is probable that the temporary difference will not reverse in the 
foreseeable future.

Accounting policies (continued) 
Provisions and contingencies 
Provisions are recognised when the group has a present obligation as a result of a past event 
and a reliable estimate can be made of a probable adverse outcome, for example warranties, 
environmental claims and restructuring. Otherwise, material contingent liabilities are disclosed 
unless the probability of the transfer of economic benefits is remote. Contingent assets are only 
recognised if an inflow of economic benefits is virtually certain. 
Share-based payments and treasury shares 
The fair value of shares awarded to employees under the performance share plan,  
restricted share plan, long term incentive plan and deferred bonus plan is calculated by 
adjusting the share price on the date of allocation for the present value of the expected 
dividends that will not be received. The resulting cost is charged to the income statement over 
the relevant performance periods, adjusted to reflect actual and expected levels of vesting 
where appropriate. 
The group and parent company provide finance to the employee share ownership trust (ESOT) 
to purchase company shares in the open market. Costs of running the ESOT are charged to the 
income statement. The cost of shares held by the ESOT is deducted in arriving at equity until 
they vest unconditionally with employees. 
Post-employment benefits 
The costs of defined contribution plans are charged to the income statement as they fall due. 
For defined benefit plans, the group and parent company recognise the net assets or liabilities 
of the plans in their balance sheets. Assets are measured at their fair value at the balance sheet 
date. Liabilities are measured at present value using the projected unit credit method and a 
discount rate reflecting yields on high quality corporate bonds. The changes in plan assets and 
liabilities, based on actuarial advice, are recognised as follows: 
• The current service cost is deducted in arriving at operating profit. 
• The net interest cost, based on the discount rate at the beginning of the year, contributions 
paid in and the present value of the net defined benefit liabilities during the year, is included 
in finance costs. 
• Past service costs and curtailment gains and losses are recognised in operating profit at the 
earlier of when the plan amendment or curtailment occurs and when any related 
restructuring costs or termination benefits are recognised. 
• Gains or losses arising from settlements are included in operating profit when the 
settlement occurs. 
• Remeasurements, representing returns on plan assets, excluding amounts included in 
interest, and actuarial gains and losses arising from changes in financial and demographic 
assumptions, are recognised in other comprehensive income. 
Assets held for sale and discontinued operations 
Non-current assets and disposal groups are classified as held for sale, if available for sale in its 
present condition and a sale is considered highly probable within 12 months. They are 
measured at the lower of their carrying amount and fair value less costs to sell. Assets and 
liabilities classified as held for sale are presented separately on the Balance Sheet. The assets are 
not depreciated or amortised while they are classified as held for sale.  
An impairment loss is recognised in the Income Statement for any initial or subsequent write-
down of the asset or disposal group to fair value less costs to sell. A gain is recognised for any 
subsequent increases in fair value less costs to sell of an asset or disposal group, but not in 
excess of any cumulative impairment loss previously recognised. A gain or loss not previously 
recognised by the date of the sale of the non-current asset (or disposal group) is recognised at 
the date of de-recognition. 
A discontinued operation is a component of the group’s business that either has been disposed 
of, or that is classified as held for sale and represents a separate major line of business or 
geographical area of operations, is part of a single co-ordinated plan to dispose of a separate 
major line of business or geographical area of operations or is a subsidiary acquired exclusively 
with a view to resale. 
Classification as a discontinued operation occurs at the earlier of disposal or when the operation 
meets the criteria to be classified as held for sale. The results of discontinued operations are 
presented separately in the Income Statement. When an operation is classified as a 
discontinued operation, the comparative Income Statement and Statement of Total 
Comprehensive Income is restated as if the operation had been discontinued from the start of 
the comparative year. 
Sources of estimation uncertainty 
Determining the carrying amounts of certain assets and liabilities at the balance sheet date 
requires estimation of the effects of uncertain future events. In the event that actual outcomes 
differ from those estimated, there may be an adjustment to the carrying amounts of those 
assets and liabilities within the next financial year. Other significant risks of material adjustment 
are the valuation of the liabilities of the defined benefit pension plans and tax provisions. The 
group and parent company have considered the refining process and stocktakes, deferred tax 
assets and climate change and, whilst not deemed to represent a significant risk of material 
adjustment to the group’s and parent company’s financial position during the year ending 
31st March 2024, represent important accounting estimates. 
Goodwill, other intangibles and other assets 
The group and parent company have significant intangible assets from both business 
acquisitions and investments in new products and technologies. Some of those acquisitions and 
investments are at an early stage of commercial development and, therefore, carry a greater 
risk that they will not be commercially viable. Goodwill and intangible assets not yet ready for 
use are not amortised but are subject to annual impairment reviews. Other intangible assets are 
amortised from the time they are first ready for use and, together with other assets, are assessed 
for impairment when there is a triggering event that provides evidence that they are impaired.

Accounting policies (continued) 
The impairment reviews require the use of estimates of future profit and cash generation based 
on financial budgets and plans approved by management, generally covering a three-year 
period and then extrapolated using long term growth rates, and the pre-tax discount rates used 
in discounting projected cash flows, see note 5. 
The Directors have determined that there is significant accounting judgement with respect to 
the estimated cash flows in assessing the value in use of the Hydrogen Technologies CGU given 
the slower pace of hydrogen and fuel cell market development. Refer to note 5 for information 
about the key assumptions applied in the value in use calculation. 
Post-employment benefits 
The group’s and parent company’s defined benefit plans are assessed annually by qualified 
independent actuaries. The estimate of the liabilities of the plans is based on a number of 
actuarial assumptions. 
There is a range of possible values for each actuarial assumption and the point within that range 
is estimated to most appropriately reflect the group’s and parent company’s circumstances. 
Small changes in these assumptions can have a significant impact on the estimate of the 
liabilities of the plans. A description of those discount rate and inflation assumptions, together 
with sensitivity analysis, is set out in note 24 to the group and parent company accounts. 
Tax provisions 
Tax provisions are determined based on the tax laws and regulations that apply in each of the 
jurisdictions in which the group operates. Tax provisions are recognised where the impact of 
those laws and regulations is unclear and it is probable that there will be a tax adjustment 
representing a future outflow of funds to a tax authority or a consequent adjustment to the 
carrying value of a tax asset. 
Provisions are measured using the best estimate of the most likely amount, being the most 
likely amount in a range of possible outcomes. The resolution of tax positions taken by the 
group can take a considerable period of time to conclude and, in some cases, it is difficult to 
predict the outcome. Group current income tax liabilities at 31st March 2024 of £77 million 
(2023: £106 million) include tax provisions of £64 million (2023: £97 million) and the 
estimation of the range of possible outcomes is an increase in those liabilities by £72 million 
(2023: £66 million) to a decrease of £54 million (2023: £55 million). The estimates made 
reflect where the group faces routine tax audits or is in ongoing disputes with tax authorities; 
has identified potential tax exposures relating to transfer pricing; or is contesting the tax 
deductibility of certain business costs. 
Deferred tax assets 
Deferred tax assets are recognised to the extent it is probable that future taxable profits will be 
available, against which the deductible temporary difference can be utilised, based on 
management’s assumptions relating to future taxable profits. 
Determination of future taxable profits requires application of judgement and estimates, 
including: market share, expected changes to selling prices, product profitability, precious 
metal prices and other direct input costs, based on management’s expectations of future 
changes in the markets using external sources of information where appropriate. The estimates 
take account of the inherent uncertainties, constraining the expected level of profit as 
appropriate. Changes in these estimates will affect future profits and therefore the recoverability 
of the deferred tax assets. 
Refining process and stocktakes 
The group’s and parent company’s refining businesses process significant quantities of precious 
metal and there are uncertainties regarding the actual amount of metal in the refining system 
at any one time. The group’s refining businesses process over four million ounces of platinum 
group metals per annum with a market value of around £5 billion. The majority of metal 
processed is owned by customers and the group and parent company must return pre-agreed 
quantities of refined metal based on assays of starting materials and other contractual 
arrangements, such as the timing of the return of metal. The group and parent company 
calculate the profits or losses of their refining operations based on estimates, including the 
extent to which process losses are expected during refining. The risk of process losses or 
stocktake gains depends on the nature of the starting material being refined, the specific 
refining processes applied, the efficiency of those processes and the contractual arrangements.  
Stocktakes are performed to determine the volume and value of metal within the refining system 
compared with the calculated estimates, with the variance being a profit or a loss. Stocktakes are, 
therefore, a key control in the assessment of the accuracy of the profit or loss of refining operations. 
Whilst refining is a complex, large-scale industrial process, the group and parent company have 
appropriate processes and controls over the movement of material in their refineries. 
Climate change 
The impact of climate change presented in the group’s Strategic Report (see pages 53 to 61) 
and the stated net zero targets have been considered in preparing the group accounts.  
The following considerations were made: 
• Impact on the going concern period and viability of the group over the next three years. 
The latest forecasts reflect the continuous investment in sustainable technologies including 
commercialisation of our products used in green hydrogen production and higher performance 
fuel cell components for a range of automotive, non-automotive and stationary applications. 
The potential impact of climate change on a number of areas within the financial statements 
has been considered, including: 
• The forecasts of cash flows used in impairment assessments for the carrying value of non-
current assets including goodwill (see note 5). 
• When considering the recoverability of deferred tax assets, the taxable profit forecasts  
are based on the same information used to support the going concern and impairment 
assessments. 
• The expected lives of fixed assets and their exposure to the physical risk posed by climate change. 
The expected lives of property, plant and equipment tends to be short to medium term, as such 
the physical risk posed by climate change in the long term is low.

Judgements made in applying accounting policies 
Metal 
The group and parent company use precious metal owned by customers in their production 
processes. It has been determined that this metal is not controlled by the group or parent 
company and, therefore, it is not recognised on the balance sheet.  
The group and parent company manage precious metal inventories by entering into physically 
settled forward sales and purchases of metal positions in line with a well-established hedging 
policy. The own use exemption has been adopted for these transactions and, therefore, the 
group and parent company do not fair value such physically settled contracts. 
The group undertakes linked contracts to sell or buy precious metal and commits to repurchase 
or sell the metal in the future to manage inventory levels. Accordingly, cash flows in respect of 
sale and repurchase agreements are shown as cash flows from operating activities in the cash 
flow statement rather than cash flows from financing activities. 
Provisions and contingent liabilities 
The group is involved in various disputes and claims which arise from time to time in the course 
of its business including, for example, in relation to commercial matters, product quality or 
liability, employee matters and tax audits. The group is also involved from time to time in the 
course of its business in legal proceedings and actions, engagement with regulatory authorities 
and in dispute resolution processes. Judgement is required to determine if an outflow of 
economic resources is probable, or possible but not probable for such events. Where it is 
probable, a liability is recognised and further judgement is used to determine the amount of the 
provision. Where it is possible but not probable, further judgement is used to determine if the 
likelihood is remote, in which case no disclosures are provided; if the likelihood is not remote 
then a contingent liability is disclosed. Provisions and contingent liabilities are set out in notes 
22 and 32, respectively. 
In the course of preparing the accounts, no other judgements have been made in the process of 
applying the group’s and parent company’s accounting policies, other than those involving 
estimations, that have had a significant effect on the amounts recognised in the accounts. 
Changes in accounting policies 
Amendments to accounting standards 
The International Accounting Standards Board (IASB) has issued the following amendments, 
which have been endorsed by the UK Endorsement Board, for annual periods beginning on or 
after 1st January 2023: 
• Amendments to IFRS 17, Insurance Contracts; 
• Amendments to IAS 1 and IFRS Practice Statement 2;  
• Amendments to IAS 8, Accounting Policies, Changes in Accounting Estimates and Errors; and 
• Amendments to IAS 12, Deferred Tax related to Assets and Liabilities arising from a 
Single Transaction 
These changes have not had a material impact on the group.  
On the 19th July 2023, the UK endorsed the amendments to IAS 12 Income Taxes, issued by the 
International Accounting Standards Board on 23rd May 2023, which grants companies a 
temporary exemption from applying IAS 12 to the International Tax Reform: Pillar Two Model 
Rules. The group has adopted the amendments to IAS 12 and applied the exception to 
recognising and disclosing information about deferred tax assets and liabilities related to Pillar 
Two income taxes. Refer to note 9 for further details. 
The following are accounting standards to be adopted by the group in future reporting periods; 
they have not yet been endorsed by the UK Endorsement Board: 
• IFRS 18, Presentation and Disclosure in Financial Statements, published by the IASB on 
9th April 2024 and effective for accounting periods commencing 1st January 2027; and 
• IFRS 19, Subsidiaries without Public Accountability, published by the IASB on 9th May 2024 
and effective for accounting periods commencing 1st January 2027.  
The group will assess the impact of these new accounting standards in due course following 
endorsement by the UK Endorsement Board. 
The group has not early adopted any standard, interpretation or amendment that was issued 
but is not yet effective. The group does not expect these amendments to have a material impact 
on the group. 
The list of amendments considered in relation to the above are as follows: 
• Amendments to IAS 1, Classification of liabilities as current and non-current and non-current 
liabilities with covenants; 
• Amendments to IFRS 16, Lease liability in a sale and leaseback;  
• Amendments to IAS 7 and IFRS 7, Supplier finance arrangements; and 
• Amendments to IAS 21, The Effects of Changes in Foreign Exchange Rates 
Non-GAAP measures 
The group uses various measures to manage its business which are not defined by generally 
accepted accounting principles (GAAP). The group’s management believes these measures 
provide valuable additional information to users of the accounts in understanding the group’s 
performance. The group’s non-GAAP measures are defined and reconciled to GAAP measures in 
note 34.

1. Revenue recognition depends on whether the licence is distinct in the context of the contract. 
Metal revenue: Metal revenue relates to the sales of precious metals to customers, either in pure form or contained within a product. Metal revenue arises in each of the reportable segments in the 
group. Metal revenue is affected by fluctuations in the market prices of precious metals and, in many cases, the value of precious metals is passed directly on to customers. Given the high value of 
these metals this makes up a significant proportion of revenue.

Revenue judgements 
Over time revenue 
Over time revenue recognition predominantly occurs in Catalyst Technologies and PGM Services (Refining Services), see criteria for over time recognition as defined by the group’s accounting 
policies in note 1. 
Refining Services 
The majority of the metal processed by the group and parent company’s refining businesses is owned by customers and, therefore, revenue is recognised over time on the basis that the group and 
parent company are providing a service to enhance an asset controlled by the customer. The customer controls the metal throughout the refining process, the key indicators being legal ownership, 
metal price risk and that the customer has the right to claim the equivalent metal at all stages of processing.  
The performance obligation contained in all refining contracts is a service arrangement to refine customer metal to a specified quality and volume by a certain date. For a contract that has multiple 
metals, the refinement of each metal is a separate performance obligation. We receive the contracted cash fee which is set with reference to market price at the start of the contract. Upon delivery 
of the refined metal to the customer, the percentage of the refined metal that we may retain at settlement is considered to be a non-cash consideration and is recognised as part of revenue at 
fair value.  
Revenue from refining services is recognised using an output method by estimating the progress of the metal in the refining process. Once the customer metal is in the refining process it is 
commingled with metal from other customers and it is not separately identifiable. Because we have a consistent volume of metal flowing through the refinery process, we estimate that all of the 
metal in the refinery is on average 50% of the way through the process. We therefore recognise up to 50% of the revenue (cash service fee and non-cash consideration) for our services when metal 
enters the refining process. Since refining each type of metal is a separate performance obligation, once we have returned the metal to the customer, we recognise the remaining 50% of revenue 
for that particular metal while other metal may still be due to the same customer. 
Where refinery stocktakes indicate that metal recoveries have been lower than anticipated and/or allowed for in process loss provisioning, refined metal gain revenue is reduced accordingly. Where 
refinery stocktakes indicate that metal recoveries have been higher than anticipated, any incremental refining metal gain revenue is only recognised once it is highly probable that a reversal in the 
amount of cumulative revenue recognised will not occur and the metal has been sold.

Major customers 
The group received £1.4 billion of revenue from one external customer in the Clean Air business 
which represents more than 10% of the group’s revenue from external customers during the 
year ended 31st March 2024 (2023: £1.6 billion of revenue from one external customer in the 
Clean Air business). 
Unsatisfied performance obligations 
At 31st March 2024, for contracts that had an original expected duration of more than one year, 
the group had unsatisfied performance obligations of £550 million (2023 restated: 
£961 million), representing contractually committed revenue to be recognised at a future date. 
Of this amount, £321 million (2023 restated: £487 million) is expected to be recognised within 
one year and £229 million (2023 restated: £474 million) is expected to be recognised after 
one year. 
During the year we identified a prior period error in the calculation of the unsatisfied 
performance obligations. This solely impacts the disclosure note above and has resulted in a 
decrease of £6 million in the unsatisfied performance obligations disclosure, split between an 
increase of £93 million in the less than one year amount, offset by a decrease of £99 million in 
the greater than one year amount. 
Payment terms 
The group and parent company supply goods and services on payment terms that are consistent 
with those standard across the industry and it does not have any customer contracts with a 
material financing component. Where revenue is recognised over time, payment terms are 
generally consistent with the timeframe over which revenue is recognised.

Impairment losses 
Impairment testing 
The group and parent company test goodwill annually for impairment or more frequently if there 
are indications that goodwill might be impaired. For the purpose of impairment testing, assets are 
grouped at the lowest levels for which there are separately identifiable cash flows, known as cash-
generating units (CGUs). The recoverable amounts of the CGUs are determined using value in use 
calculations which generally use extrapolated cash flow projections based on financial budgets and 
plans covering a three-year period approved by management. The budgets and plans are based on 
a number of assumptions, including market share, impact of carbon pricing, expected changes to 
selling prices, product profitability, precious metal prices and other direct input costs, based on past 
experience and management’s expectations of future changes in the markets using external 
sources of information where appropriate. We also considered how climate change will affect the 
future cash flows of the CGUs based on internal and external expert guidance. 
In addition, we review the carrying amounts of the group’s and parent company’s non-
financial assets, including property, plant and equipment to determine whether any 
indications of impairment exist. Where an indication exits, the recoverable amount of the 
asset is estimated in order to determine the extent, if any, of the impairment loss. Where it is 
not possible to estimate the recoverable amount of an individual asset, we estimate the 
recoverable amount of the CGU to which the asset belongs. 
Impairment loss 
During the year ended 31st March 2024, following our review for impairment triggers, 
no impairment loss (2023: £3 million related to property, plant and equipment) has been 
recognised in the group income statement within underlying operating profit. However 
impairment losses of £70 million (2023: £10 million) have been recognised by the group in 
major impairments and restructuring (see note 6). 
Hydrogen and fuel cell market 
The carrying amount of the Hydrogen Technologies CGU comprising attributable net assets of 
£196 million of which, £138 million relates to property, plant and equipment, was tested for 
impairment at 31st March 2024 following an indicator that the recent slower pace of 
hydrogen and fuel cell market development required a formal review for possible impairment. 
No balance of goodwill is allocated to the Hydrogen Technologies CGU. The recoverability of 
the carrying amount of the Hydrogen Technologies CGU has been assessed against its 
estimated value in use at the reporting period end date applying the key assumptions detailed 
below. Following this review, management has determined that no impairment is required. 
In estimating value in use, the year-one cash flows include the additional investment expected 
to be incurred before certain assets under construction that support the group’s expansion 
plans for hydrogen technology are ready for use. Whilst the assumptions applied in the 
Hydrogen Technologies assessment for years four to ten assume growth in the business based 
on a compound annual growth rate kept broadly flat in the outer years, they also reflect a 
reduced level of demand in hydrogen fuel cells and electrolyser market in the global energy 
transition. This is a key area of management judgement which has been considered in the 
context of the group's leading technological position in the market for fuel cells and 
electrolysers but also recognising the industry challenges around scale up given the global 
value chain is in an early stage of development. Our assessment over this period has therefore 
considered: i) manufacturing capacity in existing plants where we expect to maintain volumes 
consistent with near term forecasts to meet customer demand; and ii) the expected 
manufacturing capacity following completion of certain assets under construction which is 
aligned to meet the expected growth in customer demand over the four to ten year period as 
the market develops, as is currently expected. After this period, growth is estimated to be in 
line with a long-term growth rate of 3.0%. Should the market not develop as expected or 
meet the overall market scale forecast by management, then this could give rise to an 
impairment in future periods.  
The estimated recoverable amount of the Hydrogen Technologies GCU exceeds its carrying 
amount using a pre-tax discount rate of 13.0% which is derived from the group’s post-tax 
weighted average cost of capital of 8.9% and adjusted for the risks applicable to the CGU. 
If the discount rate and long-term growth rate key assumptions were changed to 17.4% and 
(12.0)% respectively, this would, in isolation, lead to an impairment.

Goodwill 
Significant CGUs 
Goodwill arising on the acquisition of businesses is allocated, at acquisition, to the CGUs that 
are expected to benefit from that business combination. These CGUs represent the smallest 
identifiable groups of assets that generate cash inflows that are largely independent of the 
cash inflows from other groups of assets. Goodwill allocated to the significant CGUs is 
as follows:

1. Battery Systems Poland goodwill has been impaired by £6 million. Refer to note 26 for further information. 
2. Other is comprised of CGUs with goodwill balances individually less than £5 million. 
Key assumptions used in value in use 
Unallocated corporate costs are split between CGUs based on their share of contribution. 
The three-year cash flows are extrapolated using the long term average growth rates for the 
relevant products, industries and countries in which the CGUs operate.  
The expected economic life of the Heavy Duty Catalysts has been restricted to 2040 reflecting 
internal climate change targets and impact of legislation changes. In the medium term, 
growth will come from tightening emissions legislation driving demand for more 
sophisticated catalyst systems. Beyond the medium term, the world will increasingly use 
alternatives to the internal combustion engine which is reflected in the long-term decline rate 
used in our modelling. 
Pre-tax discount rates, derived from the group’s post-tax weighted average cost of capital of 
8.9% (2023: 8.0%), adjusted for the risks applicable to each CGU are used to discount these 
projected risk-adjusted cash flows.

Different long term growth rates are used for the Clean Air - Heavy Duty Catalysts CGU 
because of expected macroeconomic trends in the industry in which the business operates. 
The growth rate for years four to ten is expected to be -3.9% (2023: 2.2%). After that, growth 
is expected to decline further and, therefore, the long term growth rate above is used for year 
eleven onwards.  
Sensitivity analysis 
The headroom for the significant CGUs, calculated as the difference between net assets 
including allocated goodwill at 31st March 2024 and the value in use calculations, is shown 
below. The table also shows, for each significant CGU, the headroom assuming a 1% decrease 
in the growth rate assumption and a 1% increase in the discount rate assumption used in the 
value in use calculations.

A reduction in the Heavy Duty Catalysts CGU’s expected economic life by one year reduces 
headroom by approximately £12 million from £356 million. We don't expect an impairment 
in the near term in Clean Air despite the declining long-term assumptions. 
A reduction in operating margin of 1% in the Catalyst Technologies CGU in each of the future 
years, with no mitigating actions taken, reduces headroom by approximately £123 million 
from £253 million.

impairment reversal (see note 26). 
Major impairment and restructuring charges are shown separately on the face of the income 
statement and excluded from underlying operating profit (see note 34). 
Major impairments – the group’s net impairment charge of £70 million includes amounts 
incurred as we prepared for the disposal of our Value Businesses, of which £45 million relates 
to an impairment in Battery Systems (see note 26). The residual balance is predominantly 
comprised of £18 million recognised in relation to the recent slowdown in growth within the 
hydrogen and fuel cell market which required us to adapt to the changing demand profiles of 
our customers as they navigate this short-term uncertainty. 
Major restructuring – the group’s transformation programme was launched in May 2022 
and was designed to drive increased competitiveness, improved execution capability and 
create financial headroom to facilitate further investment in high growth areas. Restructuring 
charges of £48 million have been recognised of which £32 million relates to Johnson Matthey 
Global Solutions and IT transformation, with the remainder other redundancy and 
implementation costs. The remaining £30 million charge is predominantly related to Clean 
Air’s ongoing plant consolidation initiatives, of which the majority is redundancy and 
exit costs.

Adjustments for prior years includes current and deferred tax adjustments in respect of India, 
Malaysia, Poland and the UK, as well as adjustments in respect of provisions for uncertain 
tax positions.  
Other tax incentives includes research and development tax incentives in the UK, US 
and China. 
Other movements mainly includes movements in respect of provisions for uncertain tax 
positions and non-taxable income. 
The Group is within the scope of the OECD Pillar Two model rules. Pillar Two legislation has 
been enacted in the UK, as well as several other territories where the Group operates, and will 
come into effect in respect of the Group's next financial period (FY25). 
Since the Pillar Two legislation was not effective at the reporting date, the Group has no 
related current tax exposure. The Group applies the exception to recognising and disclosing 
information about deferred tax assets and liabilities related to Pillar Two income taxes, 
as provided in the amendments to IAS 12 issued in May 2023. 
Under the legislation, the Group will be liable to pay a top-up tax for the difference between 
its Global Anti-Base Erosion ('GloBE') effective tax rate per jurisdiction and the 15% minimum 
rate. We have undertaken an assessment of the Group’s potential to additional taxes under 
Pillar 2 based on the FY24 financial information and conclude that the Group meets the 
exemptions in the Transitional Country by Country Reporting (‘CbCR’) safe harbours in  
all tax jurisdictions in which it operates, except for Bermuda, Hong Kong, Macedonia, 
Mexico and Malaysia. 
We continue to monitor potential impacts as further guidance is published, as territories 
implement legislation to enact the rules, and as territories increase their domestic Corporate 
Tax rate in response to the OECD Pillar 2 rules. Should the Transitional CbCR safe harbours not 
apply to any of the jurisdictions in which the Group operates in FY25, the Group’s future ETR 
will be impacted with an additional current tax exposure. In the event the jurisdictions named 
above led to a Pillar 2 additional tax charge in FY25, the Group estimates that this could 
increase the Group’s Underlying ETR by c.1-2%.

As part of the disposal of our Health business in the prior year, we received £75 million in the 
form of shares which constitutes an approximately 30% equity interest in the re-branded 
business, Veranova Parent Holdco L.P. (‘Veranova’). The group has determined that it has 
significant influence and therefore has equity accounted this stake as an investment 
in associate. 
The group has disclosed a contingent liability relating to this associate, see note 32. Financial 
information for Veranova for the year to 31st March 2024 is provided below, note Veranova’s 
financial year end is 31st December. The information disclosed reflects the amounts presented 
in the financial statements of Veranova and not the group’s share of those amounts.

1. The fair value of the precious metal contracted to be sold by the group under sale and repurchase agreements is £398 million (2023: 
£215 million). 
The group enters into factoring type arrangements in a small number of countries as part of 
normal business due to longer than standard payment terms, we seek to collect payments in 
the month following sale. As at 31st March 2024, the level of these arrangements was 
approximately £165 million (31st March 2023: approximately £250 million).  
Trade receivables and contract receivables are net of expected credit losses (see note 28).

Deferred tax has not been recognised in respect of tax losses of £158 million (2023: £85 million) and other temporary differences of £8 million (2023: £23 million). Of the total tax losses, 
£69 million (2023: £30 million) is expected to expire within 5 years, £36 million within 5 to 10 years (2023: £30 million), £nil after 10 years (2023: £nil) and £53 million carry no expiry 
(2023: £25 million). These deferred tax assets have not been recognised on the basis that their future economic benefit is not probable. 
In addition, the group’s overseas subsidiaries have net unremitted earnings of £1,149 million (2023: £933 million), resulting in temporary differences of £451 million (2023: £563 million). 
No deferred tax has been provided in respect of these differences since the timing of the reversals can be controlled and it is probable that the temporary differences will not reverse in the 
foreseeable future. 
The recognition of deferred tax assets has been determined by the recoverability of those assets against future tax liabilities as determined by budgets and plans that are showing profits in relevant 
businesses. The majority of the deferred tax assets and liabilities noted above are anticipated to be realised after more than 12 months.

24 Post-employment benefits 
Group 
Background 
Pension plans 
The group operates a number of post-employment retirement and medical benefit plans 
around the world. The retirement plans in the UK, US and other countries include both 
defined contribution and defined benefit plans. 
For defined contribution plans, retirement benefits are determined by the value of funds 
arising from contributions paid in respect of each employee and the investment returns on 
those contributions prior to retirement.  
For defined benefit plans, which include final salary, career average and other types of plans 
with committed pension payments, the retirement benefits are based on factors, such as the 
employee’s pensionable salary and length of service. The majority of the group’s final salary 
and career average defined benefit retirement plans are now closed to new entrants and 
future accrual.  
Regulatory framework and governance 
The UK pension plan, the Johnson Matthey Employees’ Pension Scheme (JMEPS), is a 
registered arrangement established under trust law and, as such, is subject to UK pension, tax 
and trust legislation. It is managed by a corporate trustee, JMEPS Trustees Limited. The trustee 
board includes representatives appointed by both the parent company and employees and 
includes an independent chairman. 
Although the parent company bears the financial cost of the plan, the trustee directors are 
responsible for the overall management and governance of JMEPS, including compliance with 
all applicable legislation and regulations. The trustee directors are required by law to act in the 
interests of all relevant beneficiaries and: to set certain policies; to manage the day-to-day 
administration of the benefits; and to set the plan’s investment strategy following consultation 
with the parent company. 
UK pensions are regulated by the Pensions Regulator whose statutory objectives and 
regulatory powers are described on its website: www.thepensionsregulator.gov.uk 
The JMEPS Trustee Board considers how climate risk is integrated within investment processes 
when appointing, monitoring and withdrawing from investment managers using the 
investment consultant’s Environmental, Social and Governance (ESG) ratings. The ESG ratings 
include consideration of climate risk management policies. On a periodic basis, JMEPS will 
review the ESG ratings assigned to the underlying investments based on the investment 
consultant’s ESG research. 
The US pension plans are qualified pension arrangements and are subject to the requirements 
of the Employee Retirement Income Security Act, the Pension Protection Act 2006 and the 
Department of Labor and Internal Revenue. The plans are managed by a pension committee 
which acts as the fiduciary and, as such, is ultimately responsible for: the management of the 
plans’ investments; compliance with all applicable legislation and regulations; and overseeing 
the general management of the plans. 
Other trustee or fiduciary arrangements that have similar responsibilities and obligations are 
in place for the group’s other funded defined benefit pension plans outside of the UK and US. 
Benefits 
The UK defined benefit pension plan is segregated into two sections – a legacy section which 
provides final salary and career average pension benefits and a hybrid arrangement which 
provides three levels of membership offering cash balance and defined contribution sections.  
The legacy section provides benefits to members in the form of a set level of pension payable 
for life based on the member’s length of service and final pensionable salary at retirement or 
averaged over their career with the company. The majority of the benefits attract inflation-
related increases both before and after retirement. The final salary element of the legacy 
section was closed to future accrual of benefits from 1st April 2010 and the career average 
element of the legacy section was closed to new entrants on 1st October 2012 and closed to 
future accrual on 31st March 2024.  
The cash balance section provides benefits to members at the point of retirement in the form 
of a cash lump sum. The benefits attract inflation-related increases before retirement but, 
following the payment of the retirement lump sum benefit, the plan has no obligation to pay 
any further benefits to the member. All new employees join the defined contribution section 
but have the opportunity to switch to the cash balance section of the plan within 60 days of 
joining the Company. 
The group operates two defined benefit pension plans in the US. The hourly pension plan is for 
unionised employees and provides a fixed retirement benefit for life based upon years of 
service. The salaried pension plan provides retirement benefits for life based on the member’s 
length of service and final pensionable salary (averaged over the last five years). The salaried 
plan benefits attract inflation-related increases before leaving but are non-increasing 
thereafter. On retirement, members in either plan have the option to take the cash value of 
their benefit instead of a lifetime annuity in which case the plan has no obligation to pay any 
further benefits to the member.

The US salaried pension plan was closed to new entrants on 1st September 2013, and the US 
hourly pension plan was closed to new entrants on 1st January 2019. The hourly pension plan 
remains open to future accrual for existing members but the salaried pension plan was closed 
to future accrual from 1st July 2023 with plan participants transferring to a defined 
contribution plan. All new US employees now join a defined contribution plan. 
Other post-employment benefits 
The group’s principal post-employment medical plans are in the UK and US, and are unfunded 
arrangements that have been closed to new entrants for over ten years.

Funding 
Introduction 
The group’s principal defined benefit retirement plans are funded through separate  
fiduciary or trustee administered funds that are independent of the sponsoring company. 
The contributions paid to these arrangements are jointly agreed by the sponsoring company 
and the relevant trustee or fiduciary body after each funding valuation and in consultation 
with independent qualified actuaries. The plans’ assets, together with the agreed funding 
contributions, should be sufficient to meet the plans’ future pension obligations. 
UK valuations 
UK legislation requires that pension plans are funded prudently and that, when undertaking a 
funding valuation (every three years), assets are taken at their market value and liabilities are 
determined based on a set of prudent assumptions set by the trustee following consultation 
with their appointed actuary. The assumptions used for funding valuations may, therefore, 
differ to the actuarial assumptions used for IAS 19, Employee Benefits, accounting purposes. 
In January 2013, a special purpose vehicle (SPV), Johnson Matthey (Scotland) Limited 
Partnership, was set up to provide deficit reduction contributions and greater security to the 
trustee. The group invested £50 million in a bond portfolio which is beneficially held by the 
SPV. The income generated by the SPV is used to make annual distributions of £3.5 million to 
JMEPS for a period of up to 25 years. These annual distributions are only payable if the legacy 
section of JMEPS continues to be in deficit, on a funding basis. This bond portfolio is held as a 
non-current investment at fair value through other comprehensive income and the group’s 
liability to pay the income to the plan is not a plan asset under IAS 19 although it is for 
actuarial funding valuation purposes. The SPV is exempt from the requirement to prepare 
audited annual accounts as it is included on a consolidated basis in these accounts.  
A funding valuation of JMEPS was carried out as at 1st April 2021 and showed that there was a 
deficit of £9 million in the legacy section of the plan, or a surplus of £24 million after taking 
account of the future additional deficit contributions from the SPV. The valuation also showed 
a deficit in the cash balance section of the plan of £1 million. The next triennial actuarial 
valuation of JMEPS was carried out as at 1st April 2024 with the results known later in the year. 
In accordance with the governing documentation of JMEPS, any future plan surplus would be 
returned to the parent company by way of a refund assuming gradual settlement of the 
liabilities over the lifetime of the plan. As such, there are no adjustments required in respect of 
IFRIC 14, IAS 19 – The Limit on a Defined Benefit Asset, Minimum Funding Requirements and 
their Interaction. 
US valuations 
The last annual review of the US defined benefit pension plans was carried out by a qualified 
actuary as at 1st July 2023 and showed that there was a surplus of $18 million on the projected 
funding basis.  
The assumptions used for funding valuations may differ to the actuarial assumptions used for 
IAS 19 accounting purposes. 
Other valuations 
Similar funding valuations are undertaken on the group’s other defined benefit pension plans 
outside of the UK and US in accordance with prevailing local legislation.

Risk management 
The group is exposed to a number of risks relating to its post-retirement pension plans, the 
most significant of which are: 
Risk 
 Mitigation 
Market (investment) risk 
  
Asset returns may not move in 
line with the liabilities and may 
be subject to volatility. 
 
The group’s various plans have highly diversified 
investment portfolios, investing in a wide range of assets 
that provide reasonable assurance that no single security 
or type of security could have a material adverse impact on 
the plan. 
A de-risking strategy is in place to reduce volatility in the 
plans as a result of the mismatch between the assets and 
liabilities. As the funding level of the plans improve and hit 
pre-agreed triggers, plan investments are switched from 
return-seeking assets to liability-matching assets.  
The plans implement partial currency hedging on their 
overseas assets to mitigate currency risk. 
Interest (discount) rate risk 
  
Liabilities are sensitive to 
movements in bond yields 
(interest rates), with lower 
interest rates leading to an 
increase in the valuation of 
liabilities, albeit the impact on 
the plan’s funding level will be 
partially offset by an increase in 
the value of its bond holdings. 
 
The group’s defined benefit plans hold a high proportion of 
their assets in government or corporate bonds, which 
provide a natural hedge against falling interest rates. 
In the UK, this interest rate hedge is extended by the use of 
interest rate swaps, such that the plan is 100% hedged on 
the plan’s funding basis. The swaps are held with several 
banks to reduce counterparty risk. 
 
 
 
 
Risk
Mitigation
Inflation risk 
  
Liabilities are sensitive to 
movements in inflation,  
with higher inflation leading  
to an increase in the valuation  
of liabilities. 
 
Where plan benefits provide inflation-related increases, 
the plan holds some inflation-linked assets which  
provide a natural hedge against higher than expected 
inflation increases. 
In the UK, this inflation hedge is extended by the use of 
inflation swaps, such that the plan is 100% hedged on the 
plan’s funding basis. The swaps are held with several banks 
to reduce counterparty risk. 
Longevity risk 
  
The majority of the group’s 
defined benefit plans provide 
benefits for the life of the 
member, so the liabilities are 
sensitive to life expectancy, with 
increases in life expectancy 
leading to an increase in the 
valuation of liabilities. 
 
The group has closed most of its defined benefit pension 
plans to new entrants, replacing them with either a cash 
balance plan or defined contribution plans, both of which 
are unaffected by life expectancy.  
For the plans where a benefit for life continues to be 
payable, prudent mortality assumptions are used that 
appropriately allow for a future improvement in life 
expectancy. These assumptions are reviewed on a 
regular basis. 
Liquidity risk 
  
The pension plan may have 
insufficient access to cash to 
meet its short-term cash and 
collateral obligations, such that 
adverse scenarios could force the 
sale of a less-liquid assets at 
depressed prices. 
 
The group’s defined benefit plans hold sufficient liquid 
assets to meet its cashflow obligations and the collateral 
requirements of its inflation and interest rate hedging. This 
reduces the risk of being a forced seller of less-liquid assets. 
Contributions 
During the year, total contributions to the group’s post-employment defined benefit plans 
were £38 million (2023: £40 million). It is estimated that the group will contribute 
approximately £35 million to the post-employment defined benefit plans during the year 
ending 31st March 2025.

Qualified independent actuaries have updated the IAS 19 valuations of the group’s major defined benefit plans to 31st March 2024. The assumptions used are chosen from a range of possible

Demographic assumptions 
The mortality assumptions are based on country-specific mortality tables and, where appropriate, include an allowance for future improvements in life expectancy. In addition, where credible data 
exists, actual plan experience is taken into account. The group’s most substantial pension liabilities are in the UK and the US where, using the mortality tables adopted, the expected lifetime of 
average members currently at age 65 and average members at age 65 in 25 years’ time (i.e. members who are currently aged 40 years) is respectively:

The UK plan’s unquoted equities are assets within a pooled infrastructure fund where the underlying assets are a broad range of private infrastructure investments, diversified by geographic region, 
infrastructure sector, underlying asset type and development stage. These infrastructure assets are valued using widely recognised valuation techniques which use market data and discounted cash 
flows. The same valuation approach is used to determine the value of the swaps and insurance policies.

The UK plan’s property represents an investment in the Blackrock UK Property Fund, which is a unitised fund where the underlying assets are taken at market value. The valuation of the fund is 
independently audited by KPMG on an annual basis.  
The defined benefit pension plans do not invest directly in Johnson Matthey Plc shares and no property or other assets owned by the pension plans are used by the group.

Reimbursement rights 
A government subsidy is receivable under the US Medicare legislation as the US post-retirement medical benefits plan is actuarially equivalent to the Medicare Prescription Drug Act and there is an 
insurance policy taken out to reinsure the pension commitments of one of the small pension plans which does not meet the definition of a qualifying insurance policy. These are accounted for as 
reimbursement rights and are shown on the balance sheet in post-employment benefit net assets. 
There were no movements in the reimbursement rights during the year and the balance as at 31st March 2024 is £1 million.

Sensitivity analysis 
The calculations of the defined benefit obligations are sensitive to the assumptions used. 
The following summarises the estimated impact on the group’s main plans of a change in the 
assumption while holding all other assumptions constant. This sensitivity analysis may not be 
representative of the actual change as it is unlikely that the change in assumptions would 
occur in isolation of one another. 
Financial assumptions 
A 0.1% change in the discount rate and inflation assumptions would (increase) / decrease the 
UK and US pension plans’ defined benefit obligations at 31st March 2024 as follows: 
0.1% increase
0.1% decrease

Demographic assumptions 
A one-year increase in life expectancy would increase the UK and US pension plans' defined 
benefit obligation by £38 million and £4 million, respectively. 
Other 
In June 2023, the UK High Court (Virgin Media Limited v NTL Pension Trustees II Limited) 
ruled that certain historical amendments for contracted out defined benefit schemes were 
invalid if they were not accompanied by the correct actuarial confirmation. The judgment is 
subject to appeal and possible further intervention. The Trustee has taken legal and actuarial 
advice and the Trustee and Group are monitoring developments and will consider if there are 
any implications for the UK Pension Fund, if the ruling is upheld.

The total number of treasury shares held was 9,649,874 (2023: 10,136,428) at a total cost of 
£177 million (2023: £186 million). 
The group and parent company’s employee share ownership trust (ESOT) also buys shares on 
the open market and holds them in trust for employees participating in the group’s executive 
long term incentive plans. At 31st March 2024, the ESOT held 511,623 shares (2023: 570,053 
shares) which had not yet vested unconditionally to employees. Computershare Trustees (CI) 
Limited, as trustee for the ESOT, has waived its dividend entitlement.

A final dividend of 55.0 pence per ordinary share has been proposed by the board which will 
be paid on 6th August 2024 to shareholders on the register at the close of business on 7th June 
2024, subject to shareholders’ approval. The estimated amount to be paid is £101 million and 
has not been recognised in these accounts. 
The board is responsible for the group’s capital management including the approval of 
dividends. This includes an assessment of both the level of reserves legally available for 
distribution and consideration as to whether Johnson Matthey Plc would be solvent and 
maintain sufficient liquidity following any proposed distribution. The board has assessed the 
level of distributable profits as at 31st March 2024 and is satisfied that they are sufficient to 
support the proposed dividend. 
Other reserves 
Capital redemption reserve, The capital redemption reserve represents the cumulative 
nominal value of the company’s ordinary shares repurchased and subsequently cancelled. 
Foreign currency translation reserve, The foreign currency translation reserve comprises all 
foreign currency differences arising from the translation of the financial statements of 
foreign operations.  
Fair value through other comprehensive income reserve, The fair value through other 
comprehensive income reserve represents the equity movements on financial assets held 
within this category. 
Hedging reserve, The hedging reserve comprises the effective portion of the cumulative net 
change in the fair value of cash flow hedging instruments.  
The Foreign currency translation reserve includes a £2 million loss (2023 restated: £6 million 
loss) in relation to continuing hedge relationships and £104 million loss (2023 restated: £104 
million loss) in relation to discontinued hedge relationships. All cash flow hedge reserves 
balances relate to continuing hedge relationships. 
During the year we identified a prior period error in the calculation of the continuing and 
discontinued hedge relationships. This solely impacts the disclosure note above and has 
resulted in a decrease of £6 million to the continuing hedge relationships disclosure and an 
increase of £101 million in the discontinued hedging relationships disclosure.

26 Assets and liabilities classified as held for sale 
The group drives for efficiency and disciplined capital allocation to enhance returns, as such we continue to actively manage our portfolio. In line with this strategy and to focus on our core 
businesses, during the period we completed the sale of our Diagnostics Services business. Refer to note 27 for further information on this disposal. 
In March 2024, the group agreed to sell its Medical Device Components business expecting to realise net proceeds of £530 million which is in excess of the carrying amount of its assets. 
The business is classified as a disposal group held for sale. 
Additionally, in March, the group agreed to sell its Battery Systems business. As at 31st March 2024, the proceeds less costs to sell for the Battery Systems business are estimated to be c.£30 million 
and so an impairment of £45 million has been recognised, see note 6. This impairment has been allocated against goodwill (£6 million), property, plant and equipment (£10 million), right-of-use 
assets (£1 million) and inventories (£28 million). The business is classified as a disposal group held for sale. 
During the year we recognised an impairment reversal of £7 million for the land and buildings of our previous Battery Materials business in Poland to reflect the latest fair value less costs to sell. The 
original impairment on the land and buildings was in the year ended 31st March 2022. 
The major classes of assets and liabilities comprising the businesses classified as held for sale as at 31st March are:

Johnson Matthey Catalysts LLC 
On 15th June 2023, the group completed the sale of Johnson Matthey Catalysts LLC, its 
operations in Russia, to Catalysts and Technologies LLC for a cash consideration of £11 million. 
All assets excluding cash had previously been impaired. The sale resulted in a net loss on sale 
of £4 million due to a cumulative currency translation loss being recycled from other 
comprehensive income. 
Battery Materials Germany 
On 31st December 2023, the group completed the sale of the trade and assets (excluding 
cash) of its Battery Materials Germany business for a total consideration of £1 million. 
There was £nil profit on sale. 
Disposal related costs 
Included within loss on disposal of businesses is £9 million of disposal related costs. This is 
comprised of £7 million for the disposals of Medical Device Components (£5 million) and 
Battery Systems (£2 million) which were signed during the year and £2 million in relation to 
disposals in prior years.

28 Financial risk management 
The group’s activities expose it to a variety of financial risks, including credit risk, market risk 
and liquidity risk. Market risk includes foreign currency risk, interest rate risk and price risk. 
The financial risks are managed by the group, under policies approved by the board. The 
financial risk management is carried out by a centralised group treasury function. Group 
treasury’s role is to optimise the group’s liquidity, mitigate financial risks and provide treasury 
services to the group’s operating businesses. The group uses derivative financial instruments, 
including forward currency contracts, interest rate swaps and currency swaps, to manage the 
financial risks associated with its underlying business activities and the financing of those 
activities. Some derivative financial instruments used to manage financial risk are not 
designated as hedges and, therefore, are classified as at fair value through profit or loss. 
The group does not undertake any speculative trading activity in financial instruments. 
Credit risk 
Within certain businesses, the group derives a significant proportion of its revenue from sales 
to major customers. Sales to individual customers are large if the value of precious metals is 
included in the price. The failure of any such company to honour its debts could materially 
impact the group’s results. The group derives significant benefit from trading with its 
customers and manages the risk at many levels. Each business has a credit committee that 
regularly monitors its exposure. The Audit Committee receives a report every six months that 
details all significant credit limits, amounts due and overdue within the group, and the 
relevant actions being taken. At 31st March 2024, trade receivables for the group amounted to 
£964 million (2023: £1,304 million), excluding £31 million classified as held for sale, of 
which £792 million (2023: £1,077 million) are in Clean Air which mainly supplies car and 
truck manufacturers and component suppliers in the automotive industry. Although Clean Air 
has a wide range of customers, the concentrated nature of this industry means that amounts 
owed by individual customers can be large and, in the event that one of those customers 
experiences financial difficulty, there could be a material adverse impact on the group. 
Other parts of the group tend to sell to a larger number of customers and amounts owed tend 
to be lower. At 31st March 2024, no single outstanding balance exceeded 2% (2023: 2%) 
of revenue.  
The credit profiles of the group’s customers are obtained from credit rating agencies where 
possible and are closely monitored. The scope of these reviews includes amounts overdue and 
credit limits. The group’s exposure to credit risk is influenced mainly by the individual 
characteristics of each customer. However, risk associated with the industry and country in 
which customers operate may also influence the credit risk. The credit quality of customers is 
assessed against the appropriate credit ratings, financial strength, trading experience and 
market position to define credit limits. Controls and risk mitigants include daily monitoring of 
exposures, investing in counterparties with investment grade ratings, restricting the amount 
that can be invested with one counterparty and credit-rating mitigation techniques. Generally, 
payments are made promptly in the automotive industry and in the other markets in which 
the group operates. 
A provision matrix is used to calculate lifetime expected credit losses using historical loss rates 
based on days past due and a broad range of forward-looking information, including country 
and market growth forecasts. This year, expected credit losses on unimpaired trade and 
contract receivables reduced to £12 million (2023: £16 million) driven by a lower trade 
receivables balance. 
Trade receivables are specifically impaired when the amount is in dispute, customers are in 
financial difficulty or for other reasons which imply there is doubt over the recoverability of the 
debt. They are written off when there is no reasonable expectation of recovery, based on an 
estimate of the financial position of the counterparty. 
Movements in the allowance for credit losses on trade and contract receivables are as follows:

The group’s maximum exposure to default on trade and contract receivables is £1,079 million 
(2023: £1,429 million), of which £31 million is classified as held for sale. 
The group’s financial assets included in other receivables are all current and not impaired. 
The credit risk on cash and deposits and derivative financial instruments is limited because the 
counterparties with significant balances are banks with strong credit ratings. The exposure to 
individual banks is monitored frequently against internally-defined limits, together with each 
bank’s credit rating and credit default swap prices. At 31st March 2024, the maximum net 
exposure with a single bank for cash and deposits was £81 million (2023: £37 million), whilst 
the largest mark to market exposure for derivative financial instruments to a single bank was 
£8 million (2023: £11 million). The group also uses money market funds to invest surplus 
cash thereby further diversifying credit risk and, at 31st March 2024, the group’s exposure to 
these funds was £334 million (2023: £521 million). The amounts on deposit at the year end 
represent the group’s maximum exposure to credit risk on cash and deposits. Expected credit 
losses on cash and cash equivalents are immaterial.

Foreign currency risk 
The group operates globally with a significant amount of its profit earned outside the UK. The 
main impact of movements in exchange rates on the group’s results arises on translation of 
overseas subsidiaries’ profits into sterling. The largest exposure is to the euro and a 5% (5.8 
cent (2023: 5.8 cent)) movement in the average exchange rate for the euro against sterling 
would have had a £11 million (2023: £11 million) impact on underlying operating profit. The 
group is also exposed to the US dollar and a 5% (6.3 cent (2023: 6.0 cent)) movement in the 
average exchange rate for the US dollar against sterling would have had a £7 million (2023: 
£10 million) impact on underlying operating profit. This exposure is part of the group’s 
economic risk of operating globally which is essential to remain competitive in the markets in 
which it operates. 
The group matches foreign currency assets and liabilities (where these differ to the functional 
currency of the relevant subsidiary) to avoid the risk of a material impact on the income 
statement resulting from movements in exchange rates. The group does, however, have 
foreign exchange exposure on movements through equity related to cash flow and net 
investment hedges. A 10% depreciation or appreciation in the US dollar and euro exchange 
rates against sterling would increase / (decrease) other reserves as follows:

For the net investment hedges, these movements would be fully offset in reserves by an 
opposite movement on the retranslation of the net assets of the overseas subsidiaries. 
Investments in foreign operations 
To protect the group’s sterling balance sheet and reduce cash flow risk, the group has financed 
most of its investment in the US and Europe by borrowing US dollars and euros, respectively. 
Although much of this funding is obtained by directly borrowing the relevant currency, a part 
is achieved through currency swaps which can be more efficient and reduce costs. 
The group has designated US dollar and euro loans and a cross currency swap as hedges of net 
investments in foreign operations as they hedge changes in the value of the subsidiaries' net 
assets against movements in exchange rates. The change in the value of the net investment 
hedges from movements in foreign currency exchange rates is recognised in equity and is 
offset by an equal and opposite movement in the carrying value of the net assets of the 
subsidiaries. All critical terms of the hedging instruments and hedged items matched during 
the year and, therefore, hedge ineffectiveness was immaterial. The hedge ratio is 1:1.

Forecast receipts and payments in foreign currencies 
The group uses forward foreign exchange contracts to hedge foreign exchange exposures 
arising on forecast receipts and payments in foreign currencies. These are designated and 
accounted for as cash flow hedges. The group’s policy is to hedge between 50% and 80% of 
forecast receipts and payments in foreign currencies over the next 12 months. 
For hedges of forecast receipts and payments in foreign currencies, the critical terms of the 
hedging instruments match exactly with the terms of the hedged items and, therefore, the 
group performs a qualitative assessment of effectiveness. Ineffectiveness may arise if the 
timing of the forecast transaction changes from what was originally estimated or if there are 
changes in the credit risk of the group or the derivative counterparty. Hedge ineffectiveness 
was immaterial during the year. The hedge ratio is 1:1.

The weighted average exchange rates on sterling / US dollar and sterling / euro forward 
foreign exchange contracts are 1.26 and 0.87 (2023: 1.26 and 0.88), respectively. The 
hedged, highly probable forecast transactions denominated in foreign currencies are expected 
to occur over the next 12 months. 
Foreign currency borrowings 
The group has designated two US dollar fixed interest rate to sterling fixed interest rate cross 
currency swaps as cash flow hedges. This swap hedges the movement in the cash flows on 
$100 million of the 3.14% $130 million bonds 2025 attributable to changes in the US dollar / 
sterling exchange rate while the second swap hedges the movement in the cash flows on the 
3.00% $50 million bonds 2029 attributable to changes in the US dollar / sterling exchange 
rate. The currency swaps have similar critical terms as the hedged items, such as reference 
rate, reset dates, payment dates, maturity and notional amounts. As all critical terms matched 
during the year, hedge ineffectiveness was immaterial. The hedge ratio is 1:1. The interest 
element of the swaps is recognised in the income statement each year.

28 Financial risk management (continued) 
The group’s interest rate risk arises from fixed rate borrowings (fair value risk) and floating 
rate borrowings (cash flow risk) as well as cash deposits and short term investments. Its policy 
is to optimise interest cost and reduce volatility in reported earnings and equity. The group 
manages its risk by reviewing the profile of debt regularly and by selectively using interest rate 
swaps to maintain borrowings at competitive rates. At 31st March 2024, 63% (2023: 67%) of 
the group’s borrowings and related swaps was at fixed rates with an average interest rate of 
3.1% (2023: 3.1%). The remaining debt is floating rate. Based on the group’s borrowings and 
related swaps at floating rates, after taking into account the effect of the swaps, a 1% change 
in all interest rates during the current year would have a £5 million impact on the group’s 
profit before tax (2023: £5 million). 
The group has designated three (2023: three) fixed rate to floating interest rate swaps as fair 
value hedges as they hedge the changes in fair value of bonds attributable to changes in 
interest rates. All hedging instruments have maturities in line with the repayment dates of the 
hedged bonds and the cash flows of the instruments are consistent. All critical terms of the 
hedging instruments and hedged items matched during the year and, therefore, hedge 
ineffectiveness was immaterial.

1.  The hedged items in the current year are the 1.40% €77 million Bonds 2025 and 1.81% €90 million Bonds 2028, Interest rate swaps have 
been contracted with aligned notional amounts and maturities to the bonds with the effect that the group pays an average floating rate of six-
month LIBOR plus 0.64% on the US dollar bonds and six-month EURIBOR plus 0.94% on the euro bonds. 
Price risk 
Fluctuations in precious metal prices have an impact on the group’s financial results. Our 
policy for all manufacturing businesses is to limit this exposure by hedging against future price 
changes where such hedging can be done at acceptable cost. The group enters into forward 
precious metal price contracts for the receipt or delivery of precious metal. The group does not 
take material price exposures on metal trading. A proportion of the group’s precious metal 
inventories are unhedged due to the ongoing risk over security of supply. 
Liquidity risk 
The group’s funding strategy includes maintaining appropriate levels of working capital, 
undrawn committed facilities and access to the capital markets. We regularly review liquidity 
levels and sources of cash, and we maintain access to committed credit facilities and debt 
capital markets. At 31st March 2024, the group had borrowings under committed bank 
facilities of £nil (2023: £nil). The group also has a number of uncommitted facilities and 
overdraft lines at its disposal. 
The group has a £1 billion revolving credit facility with a maturity date of March 2027 which 
includes Environmental, Social and Governance KPIs which provides the group with a nominal 
interest saving or cost depending on our performance. 
The group has three sustainability-linked private placements (€225 million £35 million and 
$50 million). The notes have interest rates linked with Johnson Matthey’s Key Performance 
Indicator for the reduction of its Scope 1 and 2 greenhouse gas emissions and are among the 
first sustainability-linked financing in the market from a UK corporate issuer.

Offsetting financial assets and liabilities 
The group offsets financial assets and liabilities when it currently has a legally enforceable 
right to offset the recognised amounts and it intends to either settle on a net basis or realise 
the asset and settle the liability simultaneously. The following financial assets and liabilities are 
subject to offsetting or enforceable master netting arrangements:

1. Agreements with derivative counterparties are based on an ISDA Master Agreement. Under these arrangements, whilst the group does not 
have a legally enforceable right of set off, where certain credit events occur, such as default, the net position receivable from or payable to a 
single counterparty in the same currency would be taken as owing and all the relevant arrangements terminated. 
29 Fair values 
Fair value hierarchy 
Fair values are measured using a hierarchy where the inputs are: 
• Level 1 — quoted prices in active markets for identical assets or liabilities. 
• Level 2 — not level 1 but are observable for that asset or liability either directly or indirectly. 
• Level 3 — not based on observable market data (unobservable). 
Fair value of financial instruments 
Certain of the group’s financial instruments are held at fair value. The fair value of a financial 
instrument is the price that would be received to sell an asset or paid to transfer a liability in an 
orderly transaction between market participants at the balance sheet date. 
The fair value of forward foreign exchange contracts, interest rate swaps, forward precious 
metal price contracts and currency swaps is estimated by discounting the future contractual 
cash flows using forward exchange rates, interest rates and prices at the balance sheet date. 
The fair value of trade and other receivables measured at fair value is the face value of the 
receivable less the estimated costs of converting the receivable into cash. 
The fair value of money market funds is calculated by multiplying the net asset value per share 
by the investment held at the balance sheet date. 
There were no transfers of any financial instrument between the levels of the fair value 
hierarchy during the current or prior years.

investments held at fair value through other comprehensive income (£5 million). 
2. Includes forward foreign exchange contracts, forward precious metal price contracts and currency swaps. 
3. Trade receivables held in a part of the group with a business model to hold trade receivables for collection or sale. The remainder of the group 
operates a hold to collect business model and receives the face value, plus relevant interest, of its trade receivables from the counterparty 
without otherwise exchanging or disposing of such instruments. 
4. Other receivables with cash flows that do not represent solely the payment of principal and interest.

The fair values are calculated using level 2 inputs by discounting future cash flows to net 
present values using appropriate market interest rates prevailing at the year end. 
The total expense recognised during the year in respect of equity-settled share-based 
payments was £17 million (2023: £18 million). 
The group currently operates various share-based payment schemes; a Performance share 
plan (PSP), a Restricted share plan (RSP), a Deferred bonus scheme and a Share Incentive 
Plan (SIP). Further details of the directors’ remuneration under share-based payment plans 
are given in the Remuneration Report. 
From 2017, shares are awarded to certain of the group’s executive directors and senior 
managers under the PSP based on a percentage of salary and are subject to performance 
targets over a three-year period. The performance targets are based on underlying EPS 
growth, and Total Shareholder Return, and strategic and sustainability targets. 
Subject to the performance conditions being met the shares will vest after which the directors 
will be required to hold any vested shares until the fifth anniversary of the award. The 
Remuneration Committee is entitled to claw back the awards to the executive directors in 
cases of misstatement or misconduct. 
From 2017, shares are awarded to certain of the group’s executive directors and senior 
managers under the RSP based on a percentage of salary. Awards under the RSP are not 
subject to performance targets. The shares are subject only to the condition that the employee 
remains employed by the group on the vesting date (ranging from one to three years after the 
award date).

30 Share-based payments (continued) 
Deferred bonus 
A proportion of the bonus payable to executive directors and senior managers is awarded as 
shares and deferred for three years. The Remuneration Committee is entitled to claw back the 
deferred element in cases of misstatement or misconduct or other relevant reason as 
determined by it. 
All employee share incentive plan (SIP) – UK and overseas 
Under the SIP, all employees with at least one year of service with the group and who are 
employed by a participating group company are entitled to contribute up to 2.5% of base pay 
each month, subject to a £125 per month limit. The SIP trustees buy shares (partnership 
shares) at market value each month with the employees’ contributions. For each partnership 
share purchased, the group purchases two shares (matching shares) which are awarded to 
the employee. 
In the UK SIP, if the employee sells or transfers partnership shares within three years of the 
date of award, the linked matching shares are forfeited. 
In the overseas SIP, partnership shares and matching shares are subject to a three-year 
holding period and cannot be sold or transferred during that time. 
During the year, 374,840 (2023: 311,260) matching shares under the SIP were awarded to 
employees. These are nil cost awards on which performance conditions are substantially 
completed at the date of grant and, consequently, the fair value of these awards is based on 
the market value of the shares at that date.

1. The group awarded three exceptional RSP schemes on 1st August 2023 of duration one, two, and three years. 
The fair value of shares awarded was calculated using a modified Black Scholes model based on the share price at the date of award adjusted for the present value of the expected dividends that will 
not be received at an expected dividend rate. 
At 31st March 2024, the weighted average remaining contracted life of the awarded PSP shares is 1.7 years (2023: 1.4 years) and 0.6 years (2023: 1.0 years) for the awarded RSP shares.

At 31st March 2024, precious metal leases were £197 million (31st March 2023: £138 million) 
at year end prices. 
32 Contingent liabilities 
The group is involved in various disputes and claims which arise from time to time in the 
course of its business including, for example, in relation to commercial matters, product 
quality or liability, employee matters and tax audits. The group is also involved from time to 
time in the course of its business in legal proceedings and actions, engagement with 
regulatory authorities and in dispute resolution processes. These are reviewed on a regular 
basis and, where possible, an estimate is made of the potential financial impact on the group. 
In appropriate cases a provision is recognised based on advice, best estimates and 
management judgement. Where it is too early to determine the likely outcome of these 
matters, no provision is made. Whilst the group cannot predict the outcome of any current or 
future such matters with any certainty, it currently believes the likelihood of any material 
liabilities to be low, and that such liabilities, if any, will not have a material adverse effect on 
its consolidated income, financial position or cash flows. 
Following the sale of its Health business in May 2022, the purchaser of the Health business, 
Veranova Bidco LP, has issued a claim against the group in connection with: i) certain alleged 
representations said to have been made during the course of the negotiation of the sale and 
purchase agreement dated 16th December 2021 (“SPA”); and, ii) certain warranties given in 
the SPA at the time of signing. Having reviewed the claim with its advisers, the group is of the 
opinion that it has a defensible position in respect of these allegations and is vigorously 
defending its position. The outcome of the legal proceedings relating to this matter is not 
certain, since the issues of liability and quantum will be for determination by the court at trial. 
Accordingly, the group is unable to make a reliable estimate of the possible financial impact at 
this stage, if any. 
33 Transactions with related parties 
The group has a related party relationship with its associates, its post-employment benefit 
plans (note 24) and its key management personnel (below). Transactions between the 
Company and its subsidiaries, which are related parties of the Company, have been eliminated 
on consolidation and are not disclosed in this note. 
During the year the group had sales of £17 million (2023: £6 million) with Veranova. 
The amounts owed by Veranova were £1 million at 31st March 2024 (31st March 2023: 
£3 million). 
The key management of the group and parent company consist of the Board of Directors and 
the members of the Group Leadership Team (GLT). During the year ended 31st March 2024, 
the GLT had an average of 13 members (2023: 12 members). The only transactions with any 
key management personnel was compensation charged in the year which was:

34 Non-GAAP measures 
The group uses various measures to manage its business which are not defined by generally accepted accounting principles (GAAP). The group’s management believes these measures provide 
valuable additional information to users of the accounts in understanding the group’s performance. Certain of these measures are financial Key Performance Indicators which measure progress 
against our strategy.  
All non-GAAP measures are on a continuing operations basis. 
Definitions 
Measure 
Definition
Purpose
Sales1 
Revenue excluding sales of precious metals to customers and the 
precious metal content of products sold to customers. 
Provides a better measure of the growth of the group as revenue can be 
heavily distorted by year on year fluctuations in the market prices of precious 
metals and, in many cases, the value of precious metals is passed directly on 
to customers. 
Underlying operating profit2 
Operating profit excluding non-underlying items. 
Provides a measure of operating profitability that is comparable over time. 
Underlying operating profit margin1, 2 
Underlying operating profit divided by sales.  
Provides a measure of how we convert our sales into underlying operating 
profit and the efficiency of our business. 
Underlying profit before tax2 
Profit before tax excluding non-underlying items. 
Provides a measure of profitability that is comparable over time. 
Underlying profit for the year2 
Profit for the year excluding non-underlying items and related tax 
effects. 
Provides a measure of profitability that is comparable over time. 
Underlying earnings per share1, 2 
Underlying profit for the year divided by the weighted average 
number of shares in issue. 
Our principal measure used to assess the overall profitability of the group. 
Average working capital days (excluding 
precious metals)1 
Monthly average of non-precious metal related inventories, trade 
and other receivables and trade and other payables (including any 
classified as held for sale) divided by sales for the last three months 
multiplied by 90 days. 
Provides a measure of efficiency in the business with lower days driving 
higher returns and a healthier liquidity position for the group. 
Free cash flow 
Net cash flow from operating activities after net interest paid, net 
purchases of non-current assets and investments, proceeds from 
disposal of businesses, dividends received from joint ventures and 
associates and the principal element of lease payments.  
Provides a measure of the cash the group generates through its operations, 
less capital expenditure. 
Net debt (including post tax pension deficits) 
to underlying EBITDA 
Net debt, including post tax pension deficits and quoted bonds 
purchased to fund the UK pension (excluded when the UK pension 
plan is in surplus) divided by underlying EBITDA for the same period.  
Provides a measure of the group’s ability to repay its debt. The group has a 
long-term target of net debt (including post tax pension deficits) to 
underlying EBITDA of between 1.5 and 2.0 times, although in any given year 
it may fall outside this range depending on future plans. 
1. Key Performance Indicator. 
2. Underlying profit measures are before profit or loss on disposal of businesses, gain or loss on significant legal proceedings, together with associated legal costs, amortisation of acquired intangibles, major impairment and restructuring charges, share of profits or losses from non-strategic equity 
investments and, where relevant, related tax effects. These items have been excluded by management as they are not deemed to be relevant to an understanding of the underlying performance of the business. 
As noted in our 2023 annual report, our strategy involves making substantial investment in the coming years to support the growth and transformation of the group. Our businesses have different investment and return profiles and therefore we no longer use a group measure of Return on Invested 
Capital as a key performance indicator. 
Underlying profit measures exclude the following non-underlying items which are shown separately on the face of the income statement: 
• (Loss) / profit on disposal of businesses, The group recognised £9 million loss on the disposal of businesses (2023: £12 million profit), see note 27. 
• Amortisation of acquired intangibles, Amortisation and impairment of intangible assets which arose on the acquisition of businesses totalled £4 million (2023: £5 million). 
• Gains and losses on significant legal proceedings, The group recognised £nil loss on significant legal proceedings (2023: £25 million loss). 
• Major impairment and restructuring charges, The group recognised £148 million in major impairment and restructuring charges (2023: £41 million), see note 6. 
• Share of losses of associates, The group recognised £3 million for its share of losses of associates (2023: £1 million), see note 15.

Notes on the Accounts for the year ended 31st March 2024 continued 
 
36 Accounting policies - parent company 
Basis of accounting and preparation - parent company 
The accounts are prepared on a going concern basis in accordance with Financial Reporting 
Standard (FRS) 101, Reduced Disclosure Framework, issued in September 2015 and the 
Companies Act 2006 applicable to companies reporting under FRS 101. The parent company 
applies the recognition, measurement and disclosure requirements of international 
accounting standards in conformity with the requirements of the Companies Act 2006, but 
makes amendments where necessary to comply with the Act and has set out below the FRS 
101 disclosure exemptions taken by the parent company: 
• the requirements of paragraphs 45(b) and 46 to 52 of IFRS 2, Share-based Payment; 
• the requirements of IFRS 7, Financial Instruments: Disclosures; 
• the requirements of paragraphs 91 to 99 of IFRS 13, Fair Value Measurement; 
• the requirements of the second sentence of paragraph 110 and paragraphs 113(a), 114, 
115, 118, 119(a) to (c), 120 to 127 and 129 of IFRS 15, Revenue from Contracts with 
Customers; 
• the requirement in paragraph 38 of IAS 1, Presentation of Financial Statements, to present 
comparative information in respect of: paragraph 73(e) of IAS 16, Property, Plant and 
Equipment; and paragraph 118(e) of IAS 38, Intangible Assets; 
• the requirements of paragraphs 10(d), 38A, 38B, 40A, 40B, 40C, 40D, 111 and 134 to 136 
of IAS 1, Presentation of Financial Statements; 
• the requirements of IAS 7, Statement of Cash Flows; 
• the requirements of paragraphs 30 and 31 of IAS 8, Accounting Policies, Changes in 
Accounting Estimates and Errors; 
• the requirements of paragraph 17 of IAS 24, Related Party Disclosures; 
• the requirements in IAS 24, Related Party Disclosures, to disclose related party transactions 
entered into between two or more members of a group, provided that any subsidiary which 
is a party to the transaction is wholly owned by such a member; and  
• the requirements of paragraphs 130(f)(ii), 130(f)(iii), 134(d), 134(f) and 135(c) to 135(e) 
of IAS 36, Impairment of Assets. 
The accounts are prepared on the historical cost basis, except for certain assets and liabilities 
which are measured at fair value as explained below. 
The parent company has not presented its own income statement, statement of total 
comprehensive income and related notes as permitted by Section 408(3) of the Companies 
Act 2006. Profit for the year is disclosed in the parent company statement of financial position 
and statement of changes in equity. 
In the parent company statement of financial position, businesses acquired from other  
group companies are recognised at book value at the date of acquisition. The difference 
between the consideration paid and the book value of the net assets acquired is reflected in 
retained earnings. 
Material accounting policies 
The group’s and parent company’s accounting policies have been applied consistently during 
the current and prior year, other than where new policies have been adopted (see note 1). 
The group’s and parent company’s material accounting policies are consistent (see note 1) 
with the exception of the following parent company accounting policies: 
Investments in subsidiaries 
Investments in subsidiaries are stated in the parent company’s balance sheet at cost less any 
provisions for impairment. If a distribution is received from a subsidiary, the investment in that 
subsidiary is assessed for an indication of impairment. 
Provisions and contingencies 
Where the parent company enters into financial guarantee contracts to guarantee the 
indebtedness of other companies within its group, these guarantee contracts are considered 
to be contingent liabilities until such time as it becomes probable that the company will be 
required to make a payment under the guarantee. 
Sources of estimation uncertainty and judgements made in applying 
accounting policies 
The group’s and parent company’s sources of estimation uncertainty and judgements made in 
applying accounting policies are consistent – see note 1 for further information.

parent company selling metal to cover price risk on metal owned by subsidiaries. Amounts 
provided reflect management's best estimate of the expenditure required to settle the 
obligations at the balance sheet date. 
The parent company also guarantees some of its subsidiaries’ borrowings and its exposure at 
31st March 2024 was £2 million (2023: £4 million).

Basis of reporting – non-financial data
This integrated report has been prepared in accordance with the GRI Standards for the period 
1st April 2023 to 31st March 2024. Our last annual report was published in June 2023. All 
non-financial performance data is reported on a financial year basis unless otherwise stated.
Johnson Matthey compiles, assesses and discloses non-financial information to demonstrate 
to its stakeholders that it conducts its business in an ethical, responsible and sustainable 
manner and where there is a legal obligation to do so (for example, in accordance with the 
UK Companies Act, UK Stream-lined Energy and Carbon reporting (SECR) regulations, UK 
Modern Slavery Act). 
This report has been developed to incorporate the group’s significant economic, 
environmental and social impacts and is set within the context of the United Nations 
Brundtland definition of sustainability (1987) and our own sustainable business goals to 
2030. The principles of inclusivity, materiality and responsiveness help to shape the structure 
of the report and to set priorities for reporting. The report also explains how we continue to 
build sustainability into our business planning and decision-making processes and how, 
through our governance processes, we manage social, environmental and ethical matters 
across the group.
Performance data covers all sites that are under the financial control of the group, including 
all manufacturing, research and warehousing operations of Johnson Matthey Plc and its 
subsidiaries. Joint ventures where we have a minority share are not included.
For the purposes of reporting, separate businesses resident at the same location are counted 
as separate sites. Data from 76 sites was included in this report, 45 are manufacturing sites, 
15 are R&D sites and 16 are offices. Data from new facilities is included from the point at 
which the facility becomes owned by JM and operational. Selected non-financial data has been 
third-party limited assured to ISAE 3000 (Revised) standard as described on page 216-218. 
Certain employee data is included in the financial accounts and is also subject to the financial 
data third-party audit described on page 133.
Other information
Rebaselining of previous years’ data 
During the year we divested several businesses as going concerns, including our Health, 
Advanced Glass Technologies and our Battery Materials businesses.
In accordance with the recommendations of the greenhouse gas (GHG) Protocol and  
SECR reporting guidance, we have removed their historical contribution to our operational 
KPIs for all years from 2019/20, which is our baseline for our 2030 sustainability targets.  
This specifically includes our historical data for Scope 1, 2 and 3 GHG emissions, water 
consumption, waste and emissions to air.
This report contains only rebaselined numbers.
Restatements of previous years’ data in this report
In addition to rebaselining, there have been some restatements of data to account for 
improvements in methodology, coverage and quality of available data. JM’s materiality 
threshold for variance is 5%. We have made restatements of environmental performance 
data for the following KPIs this year:
•	 Emissions for Scope 3 Category 4 restated due to refinement in methodology. 
•	 Emissions for Scope 3 Category 6 restated due to improvements in methodology. 
•	 Emissions for Scope 3 Category 8 restated due to refinements in data quality.
•	 NOx, SOx and VOCs coverage restated due to improvements in methodology.
•	 Recycled PGMs restated due to calculation refinements post 2021/22 ARA publication. 
•	 Following a review of the methodologies for calculating process CH4 emissions at our 
Savannah Site values have been restated for all years from baseline year (2019/20).
•	 Calculation for Scope 1 emissions from Natural Gas has been refined following the 
divestment of our West Deptford Pharmaceutical site in 2023. All data going back to 
baseline year has subsequently been amended.
•	 During the annual assurance process a source of water use at our Royston site was noted to 
be missing from data. This has been corrected and all data going back to baseline year has 
subsequently been amended.
Material Topics 
In July 2022 we partnered with a third party 
to refresh our materiality assessment. They 
reviewed public domain opinions of our 
investors, customers and social media users, 
as well as interviewing leaders inside JM. 
Our material topics were identified as:
•	 Climate Change
•	 Air Emissions 
•	 Water and wastewater
•	 Waste management
•	 Circularity and product innovation
•	 Health and Safety
•	 Human rights
•	 Diversity and inclusion
•	 Community impact
•	 Responsible sourcing
•	 Governance and risk management
These were approved at the SVC meeting in September 2022.

Calculation methodologies for Key Performance Indicators (KPIs) 
relating to our sustainability targets for 2030
Planet: Protecting the climate
Our goal: Drive lower global greenhouse gas (GHG) emissions
This KPI is a measure of the tonnes of GHG emissions avoided during the year by using 
technologies enabled by JM’s products and solutions, compared to conventional offerings. 
The KPI captures one year’s impact for all qualifying technologies that have been operational 
during the year, as sold since 2020/21. 
Our methodology for calculating avoided GHG emissions was developed in-house and 
independently verified by EcoActTM for all product families contributing towards our target 
to ensure it complies with industry best practice. EcoAct concluded that our approach 
complied with recognised public guidelines and considered our calculations to be both fairly 
stated and representative of a balanced view of our contribution in enabling avoided 
emissions through relevant technologies. EcoAct also determined that our calculations follow 
industry best practice for measurement. Their full statement is available on request. 
For each qualifying JM technology solution, we first determine its functional unit. 
The functional unit is used to determine the boundary of the analysis, to ensure that the 
scope of the calculation covers the relevant life-cycle stages leading to the avoided emissions. 
Performance comparisons for our technology solution scenario are then made against 
identified reference scenarios, which represent current day, conventional technologies 
dominant in the market, which our emerging technologies are seeking to improve upon.
The following table gives examples of the JM technology solution families included in this 
KPI and the reference scenarios used for the calculations.

The lifetime of the technology is also considered to discount any impacts from the sale 
of previous years’ technologies if these are no longer operational and, where applicable, 
adjustments to capture changing performance over time are made.
No allocation between value chain partners is applied, since there are no established 
guidelines for this. However, our products and solutions are vital to realising the benefits 
of the technologies being used, and our KPI aims to accurately reflect JM’s role, in that 
we enable avoided GHG emissions via the use of such technologies.
Technologies that were previously included in this metric from businesses that have been 
divested during the year (Battery Materials) have been removed from the calculation and 
historical years’ performance re-baselined.

SASB Resource efficiency indicator
We have also identified revenues aligned to the SASB Chemicals Sustainability Accounting 
Standard definition of products designed for use-phase resource efficiency, which includes 
products that “through their use – can be shown to improve energy efficiency, eliminate or 
lower greenhouse gas (GHG) emissions, reduce raw materials consumption, increase product 
longevity, and/or reduce water consumption”. Qualifying products are those that either:
•	 increase the efficiency of a product during its use phase (for example, our battery 
materials and fuel cell components); or
•	 increase the efficiency of the manufacturing process used to make a product (for example, 
our catalysts and additives for the chemical, oil and gas industries).
Products beyond the scope of this assessment include those specifically designed to meet 
environmental regulatory requirements, and any product where a use-phase resource 
efficiency benefit is unclear. Revenues aligned to the use-phase resource efficiency criteria 
represent sales excluding precious metals.
Our goal: Achieve net zero by 2040
Our operational carbon footprint is reported in tonnes of carbon dioxide equivalent (CO2e) 
according to the GHG Protocol corporate standard 2015 revision, www.ghgprotocol.org and 
in with the UK Stream-lined Energy and Carbon Reporting (SECR) April 2019 requirements 
of the UK Companies Act 2006 (Strategic and Directors’ Reports) Regulations 2013.
Scope 1 GHG emissions
Our Scope 1 GHG emissions are generated by the direct burning of fuel (predominantly 
natural gas), performing chemical reactions in our manufacturing processes and driving 
company-owned or leased vehicles. They are calculated in tonnes CO2e using conversion 
factors for each energy source as published by DEFRA in June 2023 and subsequently 
amended in January 2024 – we have used the amended version. We include carbon dioxide 
(CO2), nitrous oxide (N2O), refrigerant and methane (CH4) process emissions to air in our 
Scope 1 calculations. We don’t believe we have any material Scope 1 GHG emissions of PF5 
and SF6. When calculating Global Warming Potentials (GWP) for our gaseous emissions of 
GHG we use the values published in the 6th AR from the Intergovernmental Panel on Climate 
Change (IPPC).
Scope 2 GHG emissions
Our Scope 2 GHG emissions arise from the use of electricity and steam procured from third 
parties for use at our facilities. They are calculated using the ‘dual reporting’ methodology 
outlined in the GHG Protocol corporate standard 2015 revision.
For the location-based method of Scope 2 accounting, for all facilities outside the US, we use 
national carbon intensity factors related to the consumption of grid electricity in 2021 made 
available in the 2023 edition of the world CO2 emissions database of the International Energy 
Agency. They were purchased under licence in December 2023 for sole use in company 
reporting. For US facilities we use regional carbon factors published by the Environmental 
Protection Agency in January 2024 edition of, eGRID data 2022. 
Basis of reporting – non-financial data continued
For the market-based method of Scope 2 accounting, we have applied the hierarchy of 
sources for determination of appropriate carbon intensity factors, as outlined in table 6.3 
on page 48 of the GHG Protocol Scope 2 Guidance. We have successfully obtained carbon 
intensity factors directly from our grid electricity suppliers in the EU, US and Australia. 
However, it has not been possible to obtain this information from all suppliers in China, 
India, South Africa and non-OECD Europe. 
Scope 3 GHG emissions
Our annual Scope 3 GHG emissions are reported according to the methodology of the GHG 
Protocol Corporate Value Chain (Scope 3) Accounting and Reporting Standard. A variety 
of accounting techniques were used depending on the availability of data. All value chain 
emissions over which JM has financial control are included; therefore, our Scope 3 reporting 
does not include raw materials where JM is a toll manufacturer i.e. when raw materials used 
in our factories always remain in the financial ownership of our customer.
When calculating the GHG footprint of each Scope 3 category, our principle of using the 
most accurate data sources was applied in the following order:
•	 GHG footprint data obtained directly from value chain partners
•	 Mass based calculations using carbon intensity factors from respected databases, such 
as DEFRA’s GHG reporting conversion factors and EcoInvent
•	 Financial allocation using Accenture’s proprietary Input-Output (EEIO) model. 
This combines economic data from central banks and treasury departments with research 
data from the World Bank, OECD and other leading environmental agencies.
Scope 3 GHG category as 
defined by GHG Protocol
Calculation methodology
1. Purchased goods and 
services
Where mass of purchased goods was available, this was 
used in combination with GHG intensity factors obtained 
either from suppliers or EcoInvent. For the remaining 
goods and for purchased services a financial allocation 
(EEIO model) was used
2. Capital goods
Financial allocation (EEIO model) using geographical 
breakdown of data shown in Accounting note 11 
“Property, plant & equipment” on page 168
3. Fuel- and energy-
related activities
DEFRA’s GHG reporting conversion factors 2023 were 
used to calculate well-to-tank GHG emissions from fuel 
usage, transmission and distribution losses from 
purchased electricity, and well-to-tank and transmission 
and distribution losses of energy from steam
4. Upstream 
transportation and 
distribution
Emissions data was provided by our suppliers where 
available. Otherwise, a financial allocation was made 
based on spend and intensity factors from the EEIO model
5. Waste generated in 
operations
Where GHG footprints were available from waste service 
providers they were used, otherwise DEFRA’s GHG 
reporting conversion factors 2023 were used according to 
mass of waste disposal by destination see page 43

6. Business travel
Footprint business travel for air was obtained from our 
business travel service providers, where possible. For all other 
travel – related items, distance was preferentially used for 
personal car mileage, and airfare in combination with 
DEFRA’s GHG reporting conversion factors 2023. Otherwise, 
a financial allocation was made for car rentals, hotel stay, 
and public transport based on expenses spend and intensity 
factors from the EEIO model. Accounting is by date of 
financial transaction report.
7. Employee 
commuting
Data is obtained through an annual employee survey  
of distance travelled per week by modes of transport.  
DEFRA’s GHG reporting conversion factors 2023 are used  
to calculate the GHG intensity of each transport type  
and IEA emissions factors 2023 are used to calculate 
homeworking GHG intensity.
8. Upstream leased 
assets
Financial allocation (EEIO model) using floor space and 
geographical location
9. Downstream 
transportation and 
distribution
Where JM takes responsibility for the downstream 
distribution of goods, it was included in the upstream 
category calculation. Where our customers takes 
responsibility, no data is available
10. Processing of sold 
products
Where possible, calculations have been made using the mass 
of products sold and attributing an emissions conversion 
associated with a catalyst activation step by downstream 
customers for products requiring this. For Clean Air products, 
an emission factor associated  
with manual handling/canning was used in conjunction with 
a proportion of customer Scope 1 & 2 figures from CDP data.
11. Use of sold 
products
We have removed Use of sold products from our footprint by 
agreement with SBTi, as it determined that the emissions we 
reported in this category were ‘indirect’ and should not, 
therefore, be included.
12. End of life 
treatment of sold 
products
Given no visibility of the end-of-life treatment/use of JM 
products, the mass of sold products have been mapped 
against an emission factor associated with the recycling of 
PGMs to retain the precious metals, with remainder mass 
associated with GHG emissions for combustion of waste.
13. Downstream 
leased assets
Included in Upstream leased assets category

Planet: Protecting nature and advancing the circular economy
Our goal: Conserve scarce resources
Our KPI to monitor how we are advancing the circular economy is a measurement of all % 
recycled platinum group metals in our manufactured goods on a mass basis.
We include use of five PGMs – platinum, palladium, rhodium, ruthenium and iridium in our 
target. This is defined as the weighted global average of all PGM sponge used to manufacture 
goods in our plants over the course of the reporting year and includes metal that is both 
sourced and funded by JM and metal sourced and funded by our customers. We define 
primary metal as metal from a mine or originating outside of the refining loop. This is 
measured by recording the amount of metal matching this description that has been used  
in product manufacturing over the given time-period.We define secondary or recycled  
metal as platinum-group metal-bearing material that has come from an end use  
(including post-consumer product scrap and waste materials) and has not come to  
JM in the form of ingot, concentrate or matte directly from a mining process.
This makes up the balance of metal that has been used in product manufacturing over the 
given time-period. Refining “intake” figures are based on estimated assays, based on the 
scrap etc that is sent in from customers and sampled, prior to the Refining process. 
The assay amounts are finalised throughout the year, and adjustments are periodically made 
to the reporting figures to account for any differences between the original estimated 
numbers vs. the final numbers.
Our goal: Minimise our environmental footprint
Total hazardous waste produced
This KPI is a record of how much hazardous waste we generate from our operations  
that can no longer be used by Johnson Matthey and has to be sent off site for treatment.  
We define hazardous waste in line with local regulatory requirements in the particular 
territory where the waste is generated. For example, in Europe we consider the EU Waste 
Framework Directive (Directive 2008/98/EC of the European Parliament and of the Council). 
We measure the amount of solid and liquid hazardous waste and report in metric  
tonnes of material. We measure the total weights sent off site, including any entrained 
water, and we consider all material waste no longer of use to Johnson Matthey.

We categorise its destination in the following ways:
•	 Sent outside JM for beneficial reuse.
•	 Sent outside JM for recycling.
•	 Sent outside JM for incineration with energy recovery.
•	 Sent outside JM for incineration or treatment without energy recovery.
•	 Sent outside JM for landfill disposal.
Net water usage
This KPI is a record of how much water we withdraw through our operations. 
The KPI includes all freshwater sources – mains supplied water that we receive from 
municipalities, public or private utility companies, ground water that is extracted from below 
the earth’s surface and fresh surface water that we extract from rivers, wetlands, lakes etc. 
We do not include rainwater or any brackish surface water. We subtract any water that 
is returned to the source from which it is extracted at the same or better quality.
Freshwater consumed in regions of high or extremely high baseline 
water stress 
We use the World Resource Institute’s (WRI) Water Risk Atlas tool to identify facilities which 
are located in regions with a high or extremely high baseline water stress level.

Total recordable injury and illness rate (TRIIR) is defined as the number of recordable cases 
per 200,000 hours worked in a rolling year and includes cases affecting both our employees 
and contractors.
A recordable case (as defined under the US Occupational Safety and Health Administration 
(OSHA) Regulations) is defined as a work related accident or illness that results in one or 
more of the following: absence of more than one day; medical treatment beyond first aid; 
death; loss of consciousness and restricted work or transfer to another job.
TRIIR
=
annual employee + temp + cont recordable injury/illness events x 200,000

The process safety event severity rate (PSESR) is measured according to the methodology 
approved by International Council of Chemical Associations (ICCA). The metric first requires 
a determination that the event is to be included in the process safety event severity rate 
(PSESR) calculation and then determining the severity using the severity table.
In determining this rate, 1 point is assigned for each Level 4 incident attribute, 3 points 
for each Level 3 attribute, 9 points for each Level 2 attribute, and 27 points for each Level 1 
attribute. The PSESR is recorded as a 12 month rolling number. Total worker hours include 
employees, temporary employees and contractors.
Theoretically, a process safety event could be assigned a minimum of 1 point  
(i.e. the incident meets the attributes of a Level 4 incident in only one category) or a 
maximum of 135 points (i.e. the incident meets the attributes of a Level 1 incident in  
each of the five categories).

Employee Engagement
All permanent and fixed term contract employees are invited to voluntarily complete an 
employee survey at regular intervals to determine the engagement and wellbeing of staff 
using a standard methodology defined by Workday Peakon – an independent third party 
used by companies globally. All responses are submitted confidentially to Workday Peakon 
and results are independently analysed and shared with all managers who met the minimum 
response threshold of five responses from their team. 
For reporting we use the latest survey available at the end of the fiscal year. Engagement 
level is tracked at both the Annual Survey and the Pulse Surveys, where the latter is a subset 
of questions asked to all JM employees. 
Through the surveys we measure attributes on a scale of 0 to 10. The surveys measure 
employee engagement through three questions:
1.	to what extent they would recommend JM as employer to others, 
2.	to what extent they intend to stay with JM, 
3.	in general how satisfied they are with their employment at JM.
Female representation across all management levels
This is the percentage of all management level employees (all employees whether they are a 
people manager or not, at a minimum compensation grade) who self-disclosed as female on 
the 31st March in the reporting year. 
For the purposes of reporting, we use the identifiers ‘female’ and ‘male’ for the category of 
gender as captured in our HR system. Gender is self-disclosed by the individual.
Invest in our local communities
We record the total number of employee volunteering days undertaken by permanent 
employees within their local communities, in accordance with JM’s global Employee 
Volunteering Policy. The volunteering is recorded in days, the recorded volunteering days 
may have been completed either on company time or on paid company leave. Volunteering 
done on unpaid leave, or outside normal working hours, is not included in the reported 
numbers. In determining the in-kind contribution of employees’ volunteering we take the 
number of volunteering days reported in the year and multiply it by the group average cost 
of one day of employee time.
Calculation for indirect expenditure in community investment
Number of working days in a year is five days per week for 50 weeks per year.

ERM Certification and Verification Services Limited (“ERM CVS”) was engaged by Johnson Matthey plc (“Johnson Matthey”) to provide limited assurance in relation to the selected information 
set out below and presented in the Johnson Matthey Annual Report and Accounts 2024 and Sustainability Performance Databook 2024 (together the “Reports”).
Engagement summary
Scope of our assurance 
engagement
Whether the 2023/24 selected information as indicated in the following Selected Information table are fairly presented in the Reports, in all material 
respects, in accordance with the reporting criteria.
Our assurance engagement does not extend to information in respect of earlier periods or to any other information included in the Reports.
Reporting period
1st April 2023 – 31st March 2024.
Reporting criteria
•	 The GHG Protocol Corporate Accounting and Reporting Standard (WBCSD/WRI Revised Edition 2015) for Scope 1 and Scope 2 GHG emissions
•	 The GHG Protocol Scope 2 Guidance (An amendment to the GHG Protocol Corporate Standard (WRI 2015) for Scope 2 GHG emissions
•	 The GHG Protocol Corporate Value Chain (Scope 3) Accounting and Reporting Standard (2011) for Scope 3 GHG emissions
•	 Occupational Safety and Health (OSHA) regulations
•	 Johnson Matthey’ Basis of reporting –non-financial data found in the ‘ther information’ section of Johnson Matthey’s Annual Report and Accounts 2024
Assurance standard and 
level of assurance
We performed a limited assurance engagement, in accordance with the International Standard on Assurance Engagements ISAE 3000 (Revised) ‘Assurance 
Engagements other than Audits or Reviews of Historical Financial Information’ and in accordance with ISAE 3410 for Greenhouse Gas data issued by the 
International Auditing and Assurance Standards Board.
The procedures performed in a limited assurance engagement vary in nature and timing from, and are less in extent than for a reasonable assurance 
engagement and consequently, the level of assurance obtained in a limited assurance engagement is substantially lower than the assurance that would 
have been obtained had a reasonable assurance engagement been performed.
Respective 
responsibilities
Johnson Matthey is responsible for preparing the Reports and for the collection and presentation of the information within it, and for the designing, 
implementing and maintaining of internal controls relevant to the preparation and presentation of the Selected Information.
ERM CVS’ responsibility is to provide a conclusion to Johnson Matthey on the agreed scope based on our engagement terms with Johnson Matthey, the 
assurance activities performed and exercising our professional judgement.
Our conclusion
Based on our activities, as described overleaf, nothing has come to our attention to indicate that the 2023/24 data and information for the disclosures listed under ‘Scope’ above are not fairly 
presented in the Reports, in all material respects, in accordance with the reporting criteria.

Our assurance activities
Considering the level of assurance and our assessment of the risk of material misstatement of 
the Selected Information a multi-disciplinary team of sustainability and assurance specialists 
performed a range of procedures that included, but was not restricted to, the following:
•	 Evaluating the appropriateness of the reporting criteria for the selected information;
•	 Interviewing management representatives responsible for managing the selected issues;
•	 Interviewing relevant staff to understand and evaluate the management systems and 
processes (including internal review and control processes) used for collecting and 
reporting the selected disclosures;
•	 Reviewing a sample of qualitative and quantitative evidence supporting the reported 
information at corporate level;
•	 Performing an analytical review of the year-end data submitted by all locations included in 
the consolidated 2023/24 group data for the selected disclosures which included testing 
the completeness and mathematical accuracy of conversions and calculations, and 
consolidation in line with the stated reporting boundary;
•	 Conducting in person site visits to six Johnson Matthey facilities; JM Testing Taylor 
(MI, USA), Royston R&CE (UK), Swindon (UK), Panki (India), Perstorp (Sweden) and CA 
Zhangjiagang (China), to review source data and local reporting systems and controls;
•	 Evaluating the conversion and emission factors and assumptions used; and
•	 Reviewing the presentation of information relevant to the scope of our work in the Reports 
to ensure consistency with our findings.
The limitations of our engagement
The reliability of the assured information is subject to inherent uncertainties, given the 
available methods for determining, calculating or estimating the underlying information. It 
is important to understand our assurance conclusions in this context.
For the total Scope 1 and 2 carbon intensity (market-based) and year-on-year change in 
Scope 1 and 2 carbon intensity metrics, we reviewed the accuracy of the calculation based on 
the final, assured scope 1 and 2 data and the tonne sales figure for 2023/24 provided by 
Johnson Matthey. We did not separately assure the tonne sales used in the calculation of 
these metrics.

American Depositary Receipts
Johnson Matthey has a sponsored Level 1 American Depositary Receipt (ADR) programme 
which BNY Mellon administers and for which it acts as Depositary. Each ADR represents two 
Johnson Matthey ordinary shares. The ADRs trade on the US over-the-counter (OTC) market 
under the symbol JMPLY. When dividends are paid to shareholders, the Depositary converts 
those dividends into US dollars, net of fees and expenses, and distributes the net amount 
to ADR holders.
For enquiries, BNY Mellon can be contacted on 1-888-BNY-ADRS (1-888-269-2377) toll 
free if you are calling from within the US. Alternatively, they can be contacted by e-mail 
at shrrelations@cpushareownerservices.com or via their website at www.adrbnymellon.com.

We have chosen to print on Arena Extra, a primary material paper which 
is independently certified according to the rules of the Forest Stewardship 
Council® (FSC®) and from responsible sources. We continue to educate 
ourselves and evolve our thoughts in this area as well as search for 
a secondary material paper which can offer the same consistency 
in colour, robustness and print quality to produce a clear, crisp report 
for our stakeholders. We kindly ask that once you have finished with this 
report to share it with someone who it may be of interest to or to recycle 
this as we acknowledge that primary fibres from sustainably managed 
forests are critical to maintain the paper cycle.
