VALUE-ADD SERVICE 
DISTRIBUTION MODEL
We’re a service business as much as we 
are a distribution business. We supply 
critical products that all come with a

technical expertise, responsive customer 
service, or product customisation –  
we create solutions that deliver better 
outcomes for our customers and make 
their lives easier. Our products and 
services are critical to our customers’ value 
chains and the value we deliver far exceeds 
the cost of the product. This model drives 
loyalty and share of wallet, reputation and 
market share potential, and pricing power 
and strong margins.

DAVID LOWDEN
CHAIR
 DECENTRALISED  
 CULTURE 
	 	 SHARED  
VALUES
This year has been a strong one for 
our Group, marked by both strategic 
and financial success. 
Our decentralised business model, 
characterised by its entrepreneurial 
spirit, accountability, and exceptional 
leadership, has been instrumental in 
delivering such a strong financial 
performance, with increasing resilience, 
even in challenging market conditions.
Strong financial performance 
and strategic progress
Diploma has a long track record of excellent 
shareholder returns. Over the last 15 years, 
the Group has delivered average annual 
revenue and adjusted earnings per share 
growth of 15% and 16%, respectively, 
accelerating to 20% and 18% over the last 
5 years. The Group has added to this track 
record in FY24, delivering another very 
strong financial performance. Organic 
revenue grew 6% and adjusted operating 
margins increased to 20.9%, whilst cash 
conversion exceeded 100% and ROATCE 
rose to 19.1% – up 100bps year on year, 
despite significant investment during  
the year. 
Also contributing to the performance were 
the seven high-quality businesses acquired 
during the year, adding 10% to reported 
revenue. These businesses, acquired to 
accelerate future organic growth, have had 
a strong start under Diploma’s ownership, 
particularly Peerless, which has achieved 
impressive growth since joining the Group 
in May. I am very pleased to warmly welcome 
all our new colleagues to Diploma. 
Colleagues and culture 
Our colleagues are the cornerstone 
of Diploma and are central to our identity. 
Our culture and values play a pivotal role 
in fostering employee engagement and 
development. Engaged employees are key 
to the Group’s success. That’s why we have 
introduced employee engagement as part 
of our executive remuneration package. 
Diploma fosters a shared culture  
that transcends business differences. 
This means that leaders from diverse 
industries, from healthcare to robotics, 
can collaborate, understand each other’s 
challenges, and learn from one another 
while retaining their unique identity and 
entrepreneurial spirit. 
This Group culture is demonstrated in 
common business systems, including 
our values, our financial metrics and risk 
management systems.

CHAIR’S STATEMENT CONTINUED
We have five core values that guide our 
decision-making and actions. We remain 
steadfastly customer-centric, ensuring 
that our customers’ needs remain at the 
forefront. We believe in doing the right 
thing, even when it’s challenging, because 
integrity is non-negotiable. Accountability 
is paramount, holding us responsible for 
our actions and decisions. We firmly believe 
in growing together and becoming greater 
than the sum of our parts. And finally, we 
are down to earth, maintaining a culture 
of humility and approachability. 
Our Group Colleague Engagement Survey 
continues to indicate excellent levels of 
engagement, at 79%. The results and 
learnings from this were discussed by the 
Board, and each of our businesses has  
now developed appropriate engagement 
plans to ensure we continue to create and 
maintain optimal working environments  
that support the wellbeing and success  
of our colleagues.
Board changes 
Since becoming Chair of the Board in  
2021, I have been fortunate to lead the 
appointment of four new Non-Executive 
Directors, each bringing considerable value 
to the table. With the refresh of the Board 
now complete, I am confident that we have 
a very strong Board, which is well placed to 
represent the interests of our shareholders 
and wider stakeholders in the years ahead. 
Our latest appointments are Katie 
Bickerstaffe, who joined the Board on 
1 October 2024 as Senior Independent 
Director, and Ian El-Mokadem who will take 
up the role of independent Non-Executive 
Director during the first half of the year. 
I also would like to thank the outgoing 
Non-Executive Directors, Andy Smith 
and Anne Thorburn, for their contributions 
through an incredible period of growth 
for the Group. 
Dividends
The Board has a progressive dividend policy 
that aims to increase dividend per share 
by 5% each year. The combination of very 
strong results and free cash generation, 
supported by a robust balance sheet, 
has led the Board to recommend a final 
dividend of 42.0p (2023: 40.0p) taking 
the total dividend to 59.3p (2023: 56.5p). 
Subject to shareholder approval at the 
Annual General Meeting, this dividend will  
be paid on 31 January 2025 to shareholders 
on the register at 17 January 2025 (ex-div  
16 January 2025).
Conclusion
In conclusion, it has been another 
strong year for Diploma. We have 
not only delivered an excellent financial 
performance, but have also continued 
to evolve as an organisation that values 
its people, embraces change, and remains 
resilient in the face of a changing world. Our 
commitment to our colleagues, culture, and 
values, along with our adaptive governance 
structure and sustainability initiatives, 
positions us for a prosperous and 
sustainable future.
On behalf of the Board, I would like to 
take this opportunity to thank all of our 
colleagues for their invaluable contribution 
to our success over the last year as we look 
forward to embarking on another exciting 
year of growth.

GROUP CEO
 STRONG 
 FINANCIAL 
 PERFORMANCE 
	 AND STRATEGIC 
	 PROGRESS
Our strategy is delivering. We have 
driven strong organic growth through 
end-market expansion, geographical 
penetration and product extension. 
We have continued to accelerate this 
organic growth through complementary 
acquisitions at great returns on capital. And, 
we are scaling our businesses and the Group 
to support sustainable quality compounding 
for the long term. 
We have delivered another strong year, and I 
would like to thank all my brilliant colleagues. 
These results reflect the strength of our 
value-add distribution model and diversified 
portfolio, but they are delivered by 3,600 
accountable, customer-centric people, 
thriving in our decentralised culture.
In tougher markets, we delivered 6% organic 
revenue growth. We added a further seven 
high-quality acquisitions, contributing 10% 
to reported revenue growth. We have 
improved the Group operating margin by 
120 basis points to 20.9%. We grew 
adjusted earnings per share by 15%. 
Importantly, we have delivered this with 
discipline, improving ROATCE by 100 basis 
points to 19.1%, free cashflow conversion 
remained very strong at 101%, fuelling future 
growth, and we disposed of three non-core 
businesses shortly after the year end. 
Overall, it’s been another strong year for 
the Group. 
Revenue diversification driving organic 
growth and increasing resilience
The Group’s strategy is to build high-
quality, scalable businesses for 
sustainable organic growth. 
We drive organic growth in three ways: 
expanding into structurally growing end 
markets; penetrating further into core 
developed geographies; and extending 
our product range to expand addressable 
markets. This strategy drives both sustainable 
organic growth and increased resilience. 
Execution of this strategy across our 
businesses drove organic growth of 6% 
in FY24. Double-digit growth in Controls, 
driven by market tailwinds and share gains, 
and a strong performance in Life Sciences, 
led by share gains in Canada and Australia, 
provided balance to the Seals Sector, which 
delivered a resilient performance with 
modest growth despite facing challenging 
conditions across some of its end markets.

CEO’S REVIEW

Positioning behind structurally 
growing end markets 
Throughout the year we have continued to 
drive expansion in structurally growing end 
markets, delivering both improved growth 
and increased resilience. 
Most notably in FY24, our specialty fasteners 
businesses operating in aerospace, 
Clarendon, and our recent acquisition, 
Peerless, have delivered outstanding growth 
as they have navigated the complexities of 
these markets to win share and solve their 
customers’ complex problems. Whilst we 
expect some normalisation of growth and 
margins in this market, the underlying 
growth drivers are expected to endure 
for a number of years.
Datacentres are becoming increasingly 
important to us with Windy City Wire 
delivering accelerated organic growth as 
their superior products and services are 
valued in these critical applications. As these 
centres evolve for the increased demands of 
supporting AI, a number of other Controls 
and Seals businesses are developing 
solutions, for example, to support  
liquid cooling.
In clinical diagnostics, our Life Sciences 
businesses benefitted from growing public 
and private investment in testing across a 
wide range of applications from allergy and 
autoimmune testing, to preconception and 
cancer screening. 
Electrification provides a wide range of 
growth opportunities across our businesses 
and a number of them are developing related 
offers, from solar installation kits to smart 
building solutions. This is an example of  
our businesses collaborating to create  
unique propositions.
Industrial automation is expected to 
continue to benefit from the reshoring of 
manufacturing and ageing installed bases  
of CNC machines and robots that are 
fuelling growth.
Renewables has been an area of success for 
a number of our businesses and we expect 
this to continue to build.
Water management has fuelled growth in a 
number of our Seals businesses particularly  
in Australia where our dewatering products 
and services are critical to safely extracting 
the minerals required for batteries for  
energy storage.
Whilst the infrastructure segment has been 
subdued this year, long term investment in 
infrastructure in the US, the UK and Europe will 
be a tailwind, particularly to our Seals Sector. 
Penetrating further into core 
developed economies 
There is significant scope for geographic 
expansion across our existing  
developed markets. 
With the acquisition of Peerless during the 
year, around half of the Group’s revenue 
is now generated in the US. It has also 
extended our capabilities in specialty 
fasteners beyond our previous presence 
on the West Coast of the US, to national 
coverage, as well as increasing exposure 
to the aerospace market in Europe.
The FY23 acquisition of DICSA 
established a platform for the Group 
in Spain and extended our footprint 
across Europe. We are in the early stages 
of collaboration between DICSA and R&G 
in the UK, and Hercules Aftermarket in the 
US, supporting the gradual expansion 
across these geographies. 
Following on from the integration of our 
Australian Life Sciences businesses last year 
to create a scaled business with country-
wide reach, we have recently completed 
a similar project in Canada. This enhances 
geographical coverage across the Canadian 
healthcare market providing our supply 
partners with unparalleled access across 
both medtech and diagnostics customers 
from the West to the East.
Product range extension  
Sourcing and developing new products are 
key to sustainable organic growth for all of 
our businesses, as we continually enhance 
our customer proposition for existing and 
new customers.  
In Life Sciences, it is critical that our expert 
teams remain at the forefront of product 
innovation to support their customers in 
delivering better healthcare outcomes. For 
example, the introduction of an AI-enabled 
endoscope to our Canadian portfolio is 
delivering materially higher success rates 
than a traditional scope in the identification 
of abnormalities. We are increasingly looking 
to leverage across our businesses, to bring 
successful products from one geography  
to another.
Acquisitions continue to play an important 
role in accelerating product extension. 
In our Seals Sector, we have extended 
our fluid power capabilities further 
through acquisitions into R&G, to grow our 
addressable markets. In Controls, Peerless 
specialises in airframe specialty fasteners, 
which complements Clarendon’s specialism 
in aircraft cabins. Over the coming years we 
will seek opportunities to cross-sell Peerless 
and Clarendon products. In a similar fashion, 
the acquisition of DICSA has enabled 
product expansion in R&G and Hercules 
Aftermarket, and the acquisition of PAR, 
which bolted on to R&G, drove an expanded 
seals & gaskets portfolio into the UK.
Execution of our proven strategy drove 
strong organic revenue growth of 6% 
in the year
+6%
I’d like to thank my brilliant 
colleagues for making this 
a successful year.

CEO’S REVIEW CONTINUED

Complementary acquisitions 
to accelerate growth
Diploma has a strong track record of 
accelerating organic growth through 
disciplined acquisitions with £1.3bn 
invested in over 40 businesses with 
Return on Adjusted Trading Capital 
Employed (ROATCE) of 17% in the last 
five years. In FY24, we acquired seven 
high-quality businesses for a total of 
£293m at an average EBIT multiple of 
6x: Peerless, PAR and five bolt-ons.
In May, we completed the acquisition  
of US-based Peerless for £243m. This 
extended our established position in the 
aerospace specialty fasteners market 
and is highly complementary to Clarendon, 
our existing specialty fasteners business, 
both in product offering and geographic 
footprint. Peerless has delivered an 
exceptional performance in the period since 
acquisition as positive tailwinds and share 
gains in the aerospace market have driven 
organic growth and margin expansion 
ahead of our expectations. It is expected 
to exceed 20% ROATCE in its first year in 
the Group. 
Also in May, we acquired PAR for £37m 
into R&G, adding scale to its seals & 
gasket division in the UK.
Importantly, we continue to execute 
smaller bolt-on acquisitions, completing 
five bolt-ons for £13m, with average EBIT 
multiples of 4x and expected to exceed 
20% ROATCE in year one.   
Our Life Sciences business in Canada has 
completed a significant scaling project, 
including a new facility in a more strategic 
location in the East, rationalising existing 
sites and forming two distinct East and West 
hubs. This will enhance collaboration across 
our diagnostics and medtech business, 
reduce shipment times, deliver operational 
improvements and efficiencies, and increase 
access to specialist talent. 
As well as investing in facilities and 
technology, we have also invested in talent 
and have attracted experienced leaders to 
a number of our businesses this year. Our 
Leadership at Scale programme, now in its 
second year, continues to develop leaders 
from across our businesses.
Developing sales excellence is a Group-
wide focus. Our businesses have grown 
well due to their agility, responsive 
customer service and technical capabilities. 
We want to add to that with more business 
development capability, a more strategic 
and structured approach to market 
development and great B2B sales 
processes. We’re providing the network, 
workshops, best practices and investments 
to help make this happen. 
Delivering Value Responsibly  
Across our businesses we make positive 
impacts on society and our environment 
through the delivery of life-saving healthcare 
solutions, and supporting renewable energy 
generation, water treatment and activities 
supporting the circular economy. As part of 
Diploma, our businesses place appropriate 
focus on sustainability at a level they would

works best in a decentralised culture where 
our colleagues are empowered to innovate 
and create tailored solutions. Investing in 
talent development is therefore critical: 
developing a cadre of great Managing 
Directors; building sales, supply chain and 
other functional leadership capabilities; and 
evolving teams and structures to scale our 
businesses. Ensuring we have diverse teams 
is important and whilst we have much more 
to do, I’m pleased that around half of our 
senior hires this year were women.
Ultimately, if our people are engaged, 
they will deliver the best results for our 
customers, so I’m delighted with another 
year of consistently high engagement. To 
reflect the importance of maintaining high 
engagement levels, this metric will be 
introduced into my remuneration and the 
incentive schemes of senior leaders in FY25.
We have developed 10 new facilities across 
our businesses in the last five years. In FY24, 
significant investment has been made in our 
UK wire and cable business, Shoal. Three 
previously standalone businesses have been 
combined, moving into a new state-of-the-
art shared facility with integrated 
technology and systems.
We have invested in a number of our Seals 
businesses whilst market conditions have 
been slower to position us for stronger 
growth as conditions improve. This included 
investment in talent and technology as well 
as the culmination of facilities projects in the 
UK and Europe.
The acquisitions made this year demonstrate 
the compelling proposition Diploma offers 
to owners selling their businesses: 
preserving legacies, promoting autonomy 
and accountability, and supporting growth 
through investment and expertise.
Our acquisition pipeline remains strong 
with active opportunities in all three Sectors 
across fragmented markets in our core 
geographies. We have robust processes 
in place to maximise opportunities and we 
remain a buyer of choice for the kind of 
business we look for.
Portfolio discipline is a critical component 
of sustainable quality compounding, and 
if a business no longer fits our strategy, 
we look to recycle capital. Having made four 
disposals in recent years, we made a further 
three shortly after the year end for ca. £45m 
at a 7x multiple. In the Controls Sector, 
we sold Gremtek, located in France, which 
was part of our international interconnect 
solutions business. In Seals, we disposed 
of Kubo, an OEM-focused seals business in 
Switzerland, and Pennine, a UK pneumatics 
business, that was part of R&G.

Scaling the Businesses and the Group
To deliver sustainable quality compounding, 
we must develop our businesses to deliver 
great customer propositions at scale. 
This can be through investment in talent, 
technology, and facilities – building 
capability and capacity to sustain growth 
in our businesses. It also means developing 
our Group to sustain execution as we grow.

Having a workforce rich in diverse 
perspectives will support stronger execution 
over time. I’m pleased with the progress we 
have made as we work towards gender 
balance across our Senior Management 
Team – now 30% female, up from 28% in 
FY23 and 20% in FY19 – but there is still  
work to do. 
	READ MORE ABOUT DVR ON PAGES 50-53.
Outlook 
Whilst we remain mindful of the challenging 
economic backdrop, the execution of our 
strategy gives us confidence in our ability 
to continue to deliver strong results. 
•	 Our revenue is resilient: ongoing 
diversification means we are exposed 
to structurally growing end segments.
•	 Our margins are resilient: our focus on 
value-add solutions that are critical to 
customer needs supports pricing power.
•	 Our cash flow is resilient: our low capital-
intensity model is highly cash-generative, 
underpinning a strong balance sheet. 
We remain focused on executing our 
strategy of building high-quality, scalable 
businesses for organic growth. By 
continuing to effectively balance ambition 
and discipline we are confident in continuing 
to deliver sustainable quality compounding 
over the long term.

be unlikely to do otherwise. As a result, 
they benefit from accelerated progress 
compared to their peers, which brings both 
commercial advantage and positive impact. 
Our Delivering Value Responsibly (DVR) 
framework focuses on six metrics through 
which we can have a meaningful, positive 
impact on our businesses, our people and 
our environment. I am pleased with the 
progress we have made this year, but there 
is more to be done.
Highlighting a few examples from across 
the Group in the year:
We launched a Group-wide health and 
safety programme – Stand Up for Safety – 
to provide a consistent culture, approach 
and framework. It has been very well 
received and has driven a notable change 
in behaviours by our businesses.
During the year, our target to reach net zero 
by 2045 was validated by the Science Based 
Targets initiative (SBTi). In the year we 
reduced our emissions intensity (Scope 1&2) 
to 5.7, down from 7.6 in FY23. 
Sustaining our success is dependent on our 
people. Maintaining high levels of colleague 
engagement is critical. It is a competitive 
advantage. We are once again delighted by 
excellent levels of engagement throughout 
the Group, at 79%.

 SUSTAINABLE 
	 QUALITY 
	 COMPOUNDING
Sustainable quality compounding 
combines ambition with discipline. 
Our business model and strategy are 
designed to support the delivery of 
ambitious organic growth, at high 
margins and with great capital 
returns. As a result, we have a long 
track record of delivering 
compounding earnings growth. 
Our financial model lays out how we will 
continue to deliver this in a set of medium-
term financial outcomes. This has consistently 
delivered superior shareholder returns for 
more than 25 years. We have updated our 
financial model to reflect structurally higher 
operating margins of 20%+, up from 17%+.
Diversified portfolio drives strong, 
resilient growth 
Organic growth is our first priority and each 
of our value-add businesses drives this 
through end-market expansion, geographic 
penetration and product extension. Our 
diverse portfolio of businesses means that 
this growth is both strong and resilient, with 
the Group delivering around 5% organic 
growth consistently over the long term. 
Delivering 6% organic growth in FY24 
against the backdrop of tougher markets is 
therefore particularly pleasing. In 
fragmented markets, we can accelerate this 
organic growth through carefully selected, 
disciplined acquisitions. We do not set 
specific annual targets for acquisitions, but 
our financial model demonstrates that we 
can deliver double-digit revenue growth 
within our leverage policy outlined below. 
Reported revenue growth this year of 14%  
is in line with our 15-year track record of  
15% growth.

CFO’S REVIEW

Structurally higher operating margin 
Diploma has achieved structurally higher 
operating margins, this year reaching 20.9%. 
This improvement has been driven by two 
factors: operational leverage from the 
growth of our value-add businesses, and 
recent acquisitions with accretive margins. 
Our diversified portfolio delivers a range of 
operating margins, from the teens to the 
thirties. Typically, our lower margin 
businesses have lower asset intensity, whilst 
those requiring more inventory to support 
their customer propositions are 
compensated with higher margins. 
Our financial model recognises that each 
business should deliver sustainable 
operating leverage. However, the mix 
between businesses means that, as a Group, 
we may not expand margin every year. 
This combination of growth and margin 
drives double-digit earnings per share 
growth. In FY24 we delivered 15% growth,  
in line with our 15-year track record of  
16% growth.
Consistently strong cash conversion 
Our capital-light business model drives 
strong cash conversion, targeting a 
sustainable 90%. Capital expenditure is 
carefully managed, usually accounting for 
around 2% of revenue annually. This year, 
capital expenditure was ca. 1.5% of revenue, 
with significant scaling investments made in 
new facilities in all three Sectors – in Shoal 
(Controls Sector), Life Sciences North 
America, and R&G (Seals Sector). We are 
pleased to report 101% cash conversion  
this year, ahead of our model, achieved by 
disciplined working capital management, 
and optimising inventory across  
several businesses.
Strong and improving returns
We are obsessed with delivering excellent 
returns on capital. Our key returns metric, 
Return on Adjusted Trading Capital 
Employed (ROATCE), adds back 
accounting adjustments, such as 
acquisition related amortisation, to 
ensure that our performance is driven 
by genuine economic factors. ROATCE in 
the high teens, represents returns of around 
twice our current cost of capital. Returns in 
FY24 were particularly strong. We increased 
ROATCE by 100 basis point, to 19.1%, 
the highest level in the last five years. 
Achieving this requires consistent operational 
discipline and strategic initiatives, such 
as the processes introduced by our North 
American Seals businesses to drive a 
significant reduction in inventory levels 
whilst upholding customer service levels. 
Maintaining strict discipline when making 
acquisitions is critical to sustainable, high 
returns. We have simple but strict criteria 
for potential acquisitions, and decline 
opportunities that will not meet our 20% 
ROATCE expectations. 
Our smaller bolt-on deals are expected 
to deliver 20% returns in the first year, 
and FY24 was no exception, with five new 
businesses acquired at an average EBIT 
multiple of 4x. From time to time, we will 
make larger acquisitions. We are particularly 
pleased with Peerless, which has delivered 
an excellent performance in its first five 
months, already expected to exceed 20% 
ROATCE on £243m of capital invested.
Balance sheet discipline 
Our Board policy is to maintain the net 
debt to EBITDA ratio (leverage) below 2x, 
with covenants allowing up to 3.5x (plus 
an ‘acquisition spike’). In the course of 
self-funding acquisitions, it is possible that 
we may temporarily exceed our 2x target 
for exceptional opportunities, with our 
strong free cash flow then driving leverage 
reduction at approximately 0.3x per annum. 
Whilst deploying £293m on acquisitions in 
the year, plus additional scaling investments 
across the Group, we ended FY24 with a 
leverage ratio of 1.3x.
During the year, we took further steps to 
strengthen our balance sheet to provide the 
capacity and flexibility to support sustained 
profitable growth. Building on the revolving 
credit facility refinanced in FY23, we issued 
the Group’s first US private placement notes 
in March, with a second issuance towards 
the end of FY24. 
Over the past 18 months, we have secured 
£880m in facilities, termed in tranches out 
to 2036. 
We are as disciplined about the effective 
recycling of capital as we are about its 
deployment. Over the past five years, we 
have completed seven disposals at average 
multiples of 6x, including three disposals 
following this year end.  
Progressive dividend 
Paying a progressive dividend is integral to 
our discipline and we have a 25-year track 
record of doing so. Last year, we reset our 
dividend policy, decoupling it from growth 
in earnings to grow at a more moderate 5%, 
allowing more capital for redeployment  
at high returns. 
 
FY25 guidance 
We have started FY25 well and our guidance 
for the year reflects our confidence in the 
resilience of our portfolio. At constant 
currency, organic growth is expected to  
be ca. 6% and operating margin ca. 21%. 
Acquisitions announced to date, net  
of disposals, will contribute ca. 2% to 
reported revenue.

CFO’S REVIEW CONTINUED

It is our colleagues that make 
this business special. I am proud 
of the unique culture Diploma 
has and we will continue to create 
an environment where all our 
colleagues can thrive.
Developing brilliant leaders
We need leaders who can grow 
businesses, thrive on accountability, 
inspire colleagues and create inclusive 
and high-performing cultures. This is 
what delivers sustainable growth. 
Having the right leadership in our business 
is strategically critical and our track record 
of growth means we are proactive about 
developing leadership capability.
The role of a Managing Director is 
exceptionally important at Diploma. This 
is the role that owns the business, customer 
and colleague agenda for each of our 
businesses. We are focused on ensuring 
we have the right leadership in each of these 
key positions, driving greater diversity and 
injecting strong commercial experience. 
In FY25 we will implement Leadership 
for Growth, a programme to support the 
development of this cohort with specific 
focus on inclusive leadership and driving 
organic growth. This type of intervention 
helps us to build connection and 
collaboration across our businesses, 
enabling shared learning and best practice. 
We have strengthened remuneration at this 
level with a focus on short-term incentives 
to align reward closely with performance.
Beyond Managing Directors, our focus is on 
building the bench strength required to drive 
sustainable growth. Leadership at Scale, a 
programme targeted at high potential leaders 
from across our businesses, builds the skills 
required to scale a business as it grows. 
BRILLIANT 
PEOPLE ENABLE 
OUR STRATEGY
Capability and culture are critical 
enablers of our ongoing scaling 
journey. Our decentralised and 
lean organisation, coupled with our 
growth, places particular emphasis 
on the people agenda.
We work hard to preserve our decentralised 
structure and local ownership, prizing 
minimal organisation layers to avoid 
bureaucracy and ensure agility of execution. 
In this context, we need brilliant leaders; a 
strong pipeline of future talent that reflects 
the communities within which we operate; 
and, importantly, an engaging culture that 
encourages colleagues to deliver brilliant 
service to their customers every single day. 
DONNA CATLEY 
GROUP HR DIRECTOR
Additionally, we continue to build functional 
depth across Sales, Finance, Operations and 
HR. These are critical as our businesses grow 
and scale.
Brilliant leadership, strong succession 
and strong functional expertise are critical 
enablers of growth in a lean, decentralised 
organisation and we will remain focused 
on this in years to come. 
Investing in our people
It is our workforce of ca. 3,600 colleagues 
that deliver for customers every day. 
Investing in our people and ensuring they 
can thrive in a culture of opportunity and 
development is important to our success.
We know that the experience our colleagues 
have with their managers has a profound 
impact on them. To support our managers, 
we have developed a line management 
programme to equip them with the practical 
people skills that make a difference and will 
roll this out in FY25. 
Developing the next generation of brilliant, 
skilled colleagues is important. In the UK 
we have expanded our apprenticeship 
programme to cover all key businesses, 
and we have something similar in other 
geographies. We know this works, indeed 
the Managing Director of M Seals – Thomas 
Petersen – started his career as an apprentice 
in the business. We are tremendously  
proud of this.

TALENT REVIEW

We have also invested in strengthening the 
remuneration of colleagues. Three UK 
businesses have become Real Living Wage 
employers – this strengthens their ability to 
attract and retain great talent. Beyond this, 
R&G, our largest UK employer, has signed up 
to the 5% Club, committing to 5% of their 
workforce being in ‘earn and learn’ positions.
Continuing to invest in our people, ensuring 
we have an inclusive culture across our 
businesses so that people can grow will be 
an evergreen priority for us. 
Relentless focus is applied to our senior 
hiring, and we have had notable success  
in this space with around half of vacancies 
filled by women during FY24, including 
several key business leadership positions. 
This means 38% of roles reporting directly 
into an Executive Team member are held  
by women.
We know that women can face challenges 
to career progression, to address this we 
have developed and launched Women in 
Leadership. Created from the feedback  
of over 100 women, the programme is 
supporting the ongoing development of 
female leaders across our global business. 
We actively celebrate diversity across 
Diploma and in FY24 held our inaugural 
Diploma Pride and annual Diploma 
International Women’s Day events.  
These opportunities showcase the  
amazing, diverse talent across Diploma  
and demonstrate intentional and  
inclusive leadership.
We are particularly proud of making positive 
strides in our corporate centre where 49% 
of colleagues are women and 38% of the 
team identify as belonging to an ethnic 
minority. Additionally, 11% of our workforce 
identify as an ethnic minority and 10% of  
our Top 150. Representing the communities 
within which we operate continues to be a 
focus for us. 
Culture
The success of Diploma is founded upon our 
unique culture, which is core to how we run 
the Group. Our decentralised structure is 
important, it helps us retain our culture of 
local ownership and our lean organisation 
minimises bureaucracy. We prize agility, 
pace and accountability and work actively 
to preserve this. 
We are a service business and, as we 
continue with our growth trajectory, 
preserving employee engagement is 
critical to value creation. We are proud 
of the 87% response rate in our recent 
colleague survey and our 79% engagement 
score. In FY25 we will introduce engagement 
into the remuneration of senior leaders 
across Diploma, underscoring the 
importance we place on colleagues 
and culture. 
Our people and culture are integral to our 
success, preserving what makes us unique 
whilst scaling as we grow is a critical priority. 
We have strong momentum and there is 
more to do. 
Diversity, Equity and Inclusion
Our ambition is to be an organisation where 
everyone can thrive. We have set targets to 
reach gender balance (40%+) across our 
Senior Management Team (SMT), which is 
comprised of our top ca. 150 roles, by 2030. 
We take this seriously as an Executive Team 
and recently participated in an inclusive 
leadership workshop designed to support 
our own personal leadership journey. 
Progress has been steady – 30% of the  
SMT are now women, compared with 20%  
in FY19, our efforts are intense to make 
change happen.

MARKET REVIEW

Increasing our exposure to fast 
growth markets
By executing on our disciplined growth 
strategy, we seek opportunities – both 
organically and through selective 
acquisitions – that increase exposure to 
markets with positive structural investment 
trends. Our customers in these markets have 
complex needs that are met through our 
value-add proposition. 
Continuation of this strategy will further 
increase our revenue resilience, as well  
as actively positioning us in the  
sustainable economy. 
Over the last five years, the Group has 
significantly grown its presence in 
structurally growing end markets.  
These include renewables, datacentres, 
electrification, aerospace, industrial 
automation, in vitro diagnostics,  
and infrastructure.
These markets are expected to grow by an 
annual average of between 7% and 11%. As 
well as driving growth through exposure to 
market tailwinds, we also seek to gain share 
through strategic execution.

BUSINESS MODEL

CORPORATE CENTRE
 
The role of the Corporate Centre is to support effective execution of our strategy to deliver value for our shareholders and wider stakeholders.  
There are a number of ways in which we do this:
SKILLED LEADERSHIP AND  
PERFORMANCE MANAGEMENT 
Getting the best out of our businesses requires 
skilled leaders who balance high-performance intensity 
with empowering our businesses to deliver success 
in their own way – always staying true to our powerful 
decentralised culture. Managing the mood of the 
organisation is critical. We have a lean central team 
comprising functional experts who support our 
businesses to grow and scale, whilst also delivering 
the compliance and control obligations of a FTSE 100 
Group. We dislike bureaucracy and strive to focus 
on value-adding activities that don’t place 
unnecessary burdens on our businesses.
HIGHLY EFFECTIVE CAPITAL ALLOCATION 
We are a capital-light business, investing around 
2% of revenue annually in scaling our businesses by 
upgrading facilities, enhancing the use of technology 
and investing in talent. We are selective in these scaling 
investments and require high returns from them. The 
main use of capital is to make selective acquisitions 
that will accelerate future organic growth. We have a 
clear set of criteria to determine businesses that may 
be a good fit for us, strategically and culturally:
1. a value-added customer proposition,
2. a clear growth trajectory,
3. strong leadership.
We are incredibly disciplined in our acquisition process 
and have high return thresholds. We have a strong track 
record that we intend to maintain.
STRATEGIC DIRECTION 
We have a clear Group strategy that flows through 
our Sectors, to our businesses, and results in specific 
strategic plans being set to grow and scale each 
business. These plans are set collaboratively between 
the corporate centre, the Sector and each business,  
and each leader is accountable for their delivery.  
Having incentive structures that align with our 
strategy is vitally important.
CREATING A GROUP GREATER THAN  
THE SUM OF ITS PARTS
Decentralised doesn’t mean isolated. Although our 
businesses are very diverse, there’s great value in their 
collaboration and the effects of a group network. This 
takes many forms – the sharing of expertise, experience 
and best practice; exploring cross-sell opportunities; 
leveraging customer and supplier relationships; and 
benefiting from the reputation and firepower of being 
part of a large, successful Group.
OUTPUTS
Sustainable quality compounding: Through the effective execution of our strategy, our business model enables strong organic growth, 
 consistently high returns and excellent cash generation, allowing us to reinvest in acquisitions which accelerate revenue growth,  
and pay progressive dividends to shareholders.

OUR STRATEGY

STEVE SARGEANT 
GROUP CORPORATE 
DEVELOPMENT DIRECTOR
We are long-term investors in 
our businesses. We acquire high-
quality companies, preserving 
their legacy, culture and people, 
and supporting their onward 
growth journeys. 
GROW:
Our strategy is focused on sustainable 
organic growth. We drive growth through 
our portfolio of value-add distribution 
businesses and make complementary 
acquisitions to accelerate organic growth. 
We balance ambition with discipline, driving 
sustainable growth at strong returns.
ORGANIC GROWTH IN THREE BUCKETS
We drive organic growth in three buckets by: 
positioning behind structurally growing end 
markets; penetrating further into core 
developed geographies; and extending our 
product range to expand our addressable 
markets. This drives sustainable organic 
growth and increased resilience. 
COMPLEMENTARY ACQUISITIONS DRIVE 
FUTURE ORGANIC GROWTH
We make complementary acquisitions 
to drive future organic growth, 
positioning behind fast-growing end 
markets, expanding our footprint in core 
geographies, or extending our product 
offering. Acquisitions also help us to build 
scale and resilience, bring in new talent and 
expertise, and drive great returns on capital.
The majority of our acquisitions are bolt-
ons to existing businesses but, occasionally, 
we execute larger deals which provide 
a platform for accelerated growth. 
The companies we acquire have the 
same core characteristics as our existing 
businesses: a compelling value-add 
proposition, strong organic growth potential, 
a brilliant leadership team, a good strategic 
fit, and attractive financial returns.
Occasionally, we divest businesses that 
no longer align with our strategy. We are 
long-term holders of businesses – but it 
is an important discipline in our effective 
deployment of capital. 
	LEARN MORE ABOUT OUR APPROACH TO 
ACQUISITIONS ON OUR WEBSITE
	
WWW.DIPLOMAPLC.COM/ABOUT-US/
ACQUISITIONS/
1.	 End markets
	
We have an exciting opportunity 
to access structurally high-growth 
end markets, such as renewables, 
datacentres, electrification, 
aerospace, industrial automation,  
in vitro diagnostics, and infrastructure. 
We have increased our exposure in 
these markets, but still have a very 
small share. 
2.	Geographic penetration
	
We remain focused on our core, 
developed economies of North 
America, UK, Europe, and Australasia. 
We have minimal market share – or 
none at all – in most of our product 
verticals across our core geographies 
and so we do not need to look to 
higher-risk, developing markets for 
growth. There is lots to go for in our 
established geographies.
3.	Product extension
	
We expand our addressable markets 
by extending our product offering.  
We do this through continuous 
product innovation; coordinated 
cross-selling across different Group 
businesses; or, selectively, through 
building out material new product lines 
that fit our value-add distribution 
model.
DISCIPLINED CAPITAL ALLOCATION
Diploma has made 
seven acquisitions 
and three disposals 
since the start of 
FY24 across 
Controls and 
Seals Sectors.

OUR STRATEGY: 
GROW CONTINUED

SCALE:
Our differentiators are our value-add 
business model and decentralised culture. 
As we grow, we must also scale our 
businesses and our Group to preserve and 
enhance those differentiators and ensure 
sustainable delivery for the long term.
VALUE-ADD BUSINESS MODEL AT SCALE 
Scaling is a journey that needs careful 
management in each business. Retaining 
the qualities which underpin their success 
whilst positioning each value-add business 
model to be successful at scale. In line 
with our decentralised culture, each of 
our businesses has its own scaling plan. 
Each plan includes the processes and 
core competencies that underpin it, and 
the capability – talent, technology, and 
facility – required to deliver it.
Whilst the specifics are unique to each 
business, there are core attributes and 
competencies which are common to all: 
value-add, route to market, operational 
excellence, supply chain management, 
commercial discipline, and sales 
excellence. Strengthening these 
competencies requires our businesses 
to be more strategic, structured and 
systematic. The discipline of continuous 
improvement is essential to develop 
the right capability for the future. 
	READ MORE ABOUT OUR BUSINESS MODEL 
ON PAGE 19-21
POWERFUL DECENTRALISED GROUP 
AT SCALE 
Our powerful decentralised model means 
our businesses are able to remain agile, close 
to their customers, with local accountability, 
decision-making and leadership. At the 
same time, they enjoy the benefits of 
being part of a large, multinational Group: 
networks, central expertise, collaboration, 
and best practice sharing. We follow a few 
core principles to preserve our 
decentralised culture:
We keep it focused
Portfolio discipline ensures a manageable 
platform for scale, whilst simple strategic 
and performance frameworks preserve 
local ownership but ensure alignment to 
the Group’s objectives.
We have lean structures with 
dynamic leaders
By remaining lean, we ensure agility and 
execution and avoid unnecessary 
bureaucracy. This approach requires great 
management, and so we have development 
and engagement programmes to ensure this. 
We stay in tune with the “mood”.
Being decentralised doesn’t mean that our 
businesses are isolated. Regular individual and 
collective touch points and communications 
allow us to manage pace and engagement.
	READ MORE ABOUT OUR DECENTRALISED 
CULTURE ON PAGE 15
SCALING PLATFORMS FOR SUSTAINED GROWTH
As our businesses grow, they naturally 
become more complex. The teams, 
systems and process, and facilities that 
drove success on a small scale require 
conscious development to support 
ambitious growth plans. Our strategy 
supports the individual scaling journey of 
each business to make them better, not 
just bigger businesses.

Organic revenue growth 
(%)
Our strategy is designed to 
drive organic revenue 
growth. This is our key 
metric. We have a diversified 
portfolio, giving resilience to 
revenues.
Reported revenue  
(£m)
We accelerate organic 
growth with selective 
high-quality acquisitions 
across our three Sectors. 
This metric includes organic 
growth, inorganic growth 
and the impacts of foreign 
exchange translation. 
Adjusted operating margin 
(%)
Our differentiated value-add 
solutions and customer- 
focused approach drive 
customer loyalty and create 
pricing power, supporting 
sustainable and attractive 
margins. 
Adjusted EPS  
(p)
EPS growth is a measure of 
how successful we have 
been in growing organically 
and through acquisition, 
including capital allocation 
and tax considerations.
Free cash flow conversion 
(%)
A strong balance sheet and 
cash flow fuel our growth. 
Our low-capital intensity 
enables strong cash flow 
conversion.
ROATCE  
(%)
Return on Adjusted Trading 
Capital Employed (ROATCE) 
measures how successful 
we are at generating returns 
on the investments we 
make. It holds us to account 
against initial investments 
made, ensuring our 
performance is driven by 
genuine economic factors.
In year performance:
Growth in all three Sectors. 
Double-digit growth in 
Controls and a strong 
performance in Life 
Sciences provided balance 
to more modest growth 
in Seals.
In year performance:
Strong organic growth plus 
10% contribution from 
acquisitions, partially offset 
by foreign exchange 
headwind.
In year performance: 
120 basis points increase 
year on year, reflecting 
operational leverage from 
the growth of our value-add 
businesses and recent 
acquisitions with accretive 
margins.
In year performance: 
Strong contributions from 
organic and inorganic 
growth more than offset a 
foreign exchange headwind 
and higher interest and tax 
charges 
In year performance: 
Strong cash conversion was 
driven by a focus on 
inventory optimisation across 
a number of businesses, and 
supported by low capital 
requirements in the year, at 
ca. 1.5% of revenue.  
In year performance: 
At 19.1%, returns are more 
than twice our cost of 
capital. This reflects strong 
discipline across the Group, 
including when making 
acquisitions.

Colleague engagement 
(%)
We value our colleagues and 
want them to be engaged 
and fulfilled in their roles. 
As a service-led business, 
this is a key commercial 
differentiator.
Measuring and maintaining 
high colleague engagement 
supports the delivery of 
sustainable growth and 
value creation. 
Women in Senior 
Management Team (%)
Diversity, equity and 
inclusion is a competitive 
advantage that can 
support our businesses’ 
growth by bringing diverse 
perspectives and experience 
to our workforce and driving 
stronger outcomes.
Key suppliers aligned to 
supplier code (%)
We expect our key suppliers 
to adhere to ethical, 
professional, and legal 
standards and support our 
environmental and social 
commitments. 
We ask them to work with us 
to reduce waste, emissions, 
and climate change impacts, 
and uphold human rights 
across the value chain. 
Lost time incident 
frequency rate (LTIFR)
We prioritise the safety of 
our colleagues. Embedding 
a strong health and safety 
culture and practices will 
enhance performance and 
productivity and reduce 
costs. 
Our LTIFR reflects the 
number of lost time 
incidents (LTIs) per million 
hours worked.
Total Scope 1&2 emissions
(tonnes CO2e)
We recognise the impact of 
our operations on emissions. 
Beyond the moral obligation, 
we understand that reducing 
emissions contributes to 
long-term value creation 
and supports the growth of 
our businesses. 
 
Waste to landfill 
(%)
Across our sites, reducing 
waste to landfill has a 
positive environmental 
impact and generates 
cost savings by creating 
efficiencies, such as 
reducing packaging 
and improving waste 
management processes. 
In year performance:
We achieved a consistently 
high Colleague Engagement 
Survey Index Score of 79%. 
Importantly, this was 
coupled with a high 
response rate of 87%. 
In year performance:
We made steady progress 
against our target and ran 
a number of initiatives to 
support the inclusion and 
retention of our female 
colleagues.
In year performance:
90% of key suppliers are 
aligned with our Supplier 
Code, surpassing our target 
and ensuring responsible 
practices in our value chain. 
In year performance:
Our LTIFR was 3.6. We 
continue to drive actions 
and culture on health and 
safety, which will remain an 
area of focus in FY25.
In year performance:
We reduced our Scope 1&2 
market-based emissions by 
15% against the prior year, 
largely driven by renewable 
energy procurement in 
our businesses. 
In year performance:
We reduced our proportion 
of waste to landfill to 23%

accuracy and waste 
management processes

SECTOR REVIEW: CONTROLS CONTINUED

2024 HIGHLIGHTS
12%
Strong performance in International 
Controls with organic revenue growth of 
12% driven by share gains in fast growing 
end markets. 
7%
Windy City Wire (WCW) grew organic 
revenue 7%, with particularly strong 
performance from datacentres.  
26%
Adjusted operating margin up 200 basis 
points to 26%, driven by positive leverage 
from volume growth, mix benefits and 
margin accretive acquisitions and 
disposals in the current and prior year.
Strategic acquisition of Peerless builds 
scale and expands our specialty fasteners 
presence in US and European aerospace 
and defence markets. 
International Controls has 
delivered a very strong 
performance with double-digit 
organic growth. 
It has been another great year for 
Windy City Wire and we are well 
positioned for more growth in the 
year ahead. 
RICH GALGANO
CEO, WINDY CITY WIRE
DAVID GOODE 
CEO, INTERNATIONAL  
CONTROLS
International Controls
(60%1 of Controls Sector revenue) delivered 
12% organic growth in the year. The Sector 
continues to benefit from market share 
gains and strong customer demand in civil 
aerospace and space markets as well as 
tailwinds in UK and European defence and 
energy markets as a result of sustained 
investment. In the year, International 
Controls further penetrated exciting end 
markets in medical, solar, renewables and 
eVTOL (electric Vertical Take-Off and 
Landing). Operating margin increased 
materially, driven by positive operating 
leverage on volume growth and accretion 
from the acquisition of Peerless.
Windy City Wire (WCW) 
(40%1 of Controls Sector revenue) has 
delivered another strong result, with an 
acceleration in growth in the second half, 
driven by increasing exposure to fast-
growth markets, particularly datacentres 
behind AI growth and continued expansion 
into distributed antenna systems. 
Performance in its core buildings market has 
held up well and delivered good growth in 
the year. WCW’s operating margin has 
continued to improve, benefitting from 
positive operating leverage and its growing 
presence in diversified end markets. 
Revenue diversification driving 
organic growth
Our interconnect solutions business, IS 
Group, delivered high single-digit growth, 
principally driven by strong performance in 
the UK with growth within the motorsport, 
aerospace and defence markets. Revenues 
in Germany also grew well, driven by share 
gains in the energy market and ongoing 
investment into the transmission 
infrastructure. Also in Germany, we gained 
share and benefitted from momentum in  
the growing medical market, supported  
by the acquisition of a small bolt-on,  
which widens our product offering and 
strengthens internal capability into this 
high-growth end market. 
Clarendon, one of our specialty fasteners 
businesses, delivered double-digit growth 
during the year. In the civil aerospace 
market, customer demand was high and 
Clarendon gained further share in both 
Europe and the US. Significant contract wins 
with key customers in the space market also 
contributed to the strong performance.  
We welcomed another specialty fasteners 
business, Peerless, to the Group at the start 
of May. It has made a very strong start, 
benefitting from market share gains and 
high customer demand. Like Clarendon, 
Peerless is an agile business, able to provide 
rapid and bespoke solutions for customers 
in a complex civil aerospace supply chain. 
We have won key civil aerospace and 
defence contracts covering seats, cabin and

Capital discipline 
In continuing our disciplined approach to 
portfolio management, in October 2024, we 
disposed of Gremtek, which was part of our 
international interconnect solutions 
business, for ca. £5m. Gremtek is located in 
France and supplies different end markets 
to the rest of IS Group. 
Outlook
The year has started well with continued 
momentum across the Sector.
Whilst we expect Peerless and Clarendon to 
continue delivering strong growth in the civil 
aerospace market, we expect performance 
to moderate somewhat from the high 
growth of FY24 as other businesses within 
the Sector deliver improved performance.
With increasing exposure to structurally 
growing end markets, and having invested in 
facilities, technology and talent in a number 
of businesses throughout FY24, we have 
positioned our businesses well to deliver 
another strong year of growth in FY25.
Targeted acquisitions to accelerate growth 
In May, the Sector completed the acquisition 
of Peerless for £243m, expanding our 
presence in the specialty fasteners market 
in civil aerospace and defence from the 
interior of aircraft to the airframe. This 
exciting new addition to the Sector is highly 
complementary to our Clarendon business. 
Peerless drives product expansion and 
deepens geographic penetration in the 
key US and European markets.
Two smaller bolt-on acquisitions were 
completed in the year, both in Germany.  
CTS joined the ISG group of companies, 
broadening our medical product and 
capability offering, and the addition of 
Technisil expands Techsil’s specialty 
adhesives offering in the German market.   
Building scale 
During the second half of the year, Shoal 
completed the integration of its three UK 
wire and cable businesses into one state-of-
the-art automated facility, also introducing a 
shared ERP platform. This significant project 
is pivotal to Shoal’s scaling journey and will 
deliver operational efficiencies and 
meaningful commercial benefits through 
enhanced cross-selling capabilities. A larger 
footprint increases capacity through which 
to drive future organic growth. This was a 
major change programme, and whilst it 
positions us well for the future, it did impact 
operational performance in the second  
half of the year. 
Shoal’s state-of-the-art, automated 
facility houses its newly integrated 
UK wire & cable business. This 
scaling project delivers operational 
efficiencies, better collaboration 
and cross-selling opportunities. 
the space market. We continue to diversify 
into eVTOL and UAVs (Unmanned Aerial 
Vehicles) and see these as key markets of 
the future. Geographic diversification has 
been a theme in both aerospace and 
defence with important wins in Europe  
and the US.
T.I.E., our industrial automation business, 
saw momentum towards the end of the year, 
after a more challenging start to the year, 
principally due to disruption from strike 
action in the automotive markets and 
cautious capital spending across the 
customer base. Since acquiring T.I.E. in 
FY23, we have invested in enhancing the 
commercial operation of the business, 
including expansion of the sales team to 
drive geographic expansion across the US.  
In Shoal, our UK wire and cable business, the 
impact of softer demand in UK construction 
and wholesale end markets was partially 
mitigated by stronger export sales, a strong 
solar offering and exposure to major 
infrastructure projects. Shoal is increasing 
its exposure to the fast growing datacentre 
market in the UK. In the US, Windy City Wire 
is similarly accelerating growth through its 
expansion into datacentres.

CASE STUDY

PEERLESS AEROSPACE FASTENERS
Diploma welcomed Peerless to the 
Group in May 2024. 
Peerless is a leading supplier of specialty 
fasteners to the aerospace and defence 
markets in the US and Europe.
Founded in 1952 and headquartered in 
Farmingdale, New York, Peerless has 
established itself as one of the largest 
independent value-add distributors of 
aerospace fasteners. 
Led by longstanding CEO, Bill Way, and 
President, Don Russo, the business is 
renowned for its high-quality products, 
excellent customer service, and innovative 
solutions. Customers also benefit from 
product tracking and traceability, scheduled 
inventory management, bespoke and 
automated vendor-managed inventory 
solutions, and custom kitting.
Great strategic fit
Peerless has attractive, Diploma-style 
characteristics: a clear, value-add customer 
proposition, excellent growth potential, and 
a strong management team. The acquisition 
is firmly aligned with Diploma’s strategy: 
extending our range of specialty products; 
growing our geographical footprint; and 
increasing our exposure to the fast growth 
aerospace market.
Peerless is complementary to Diploma’s 
existing Clarendon business, extending the 
product offering from aircraft cabin to 
airframe fastening solutions. The acquisition 
strengthens and expands Diploma’s 
positions in the US and Europe. In the US, it 
extends Diploma’s footprint from the West 
Coast, where Clarendon has a strong 
presence, to the East Coast.
Peerless significantly enhances Diploma’s 
capabilities and market presence in the 
attractive aerospace sector. The aerospace 
fasteners market, valued at close to £6bn, 
is highly fragmented and critical to aircraft 
manufacturing. Commercial aircraft require 
up to 400,000 individual fasteners in the 
airframe while for larger wide-body aircraft 
this rises to as many as one million. There is 
a significant production backlog in civil 
aerospace of over 10 years.
There are clear opportunities for 
Peerless and Clarendon to work together, 
leveraging their individual offerings, 
combined expertise, supplier and 
customer relationships.
Why Diploma is a good home for Peerless
Peerless has a strong culture, a history as a 
close family-run business, and it has a great 
reputation. The owners and managers of 
Peerless wanted to find the right home for 
their business – one that would preserve its 
legacy. Diploma’s track record as an 
acquirer was key to the decision, particularly 
for Bill and Don, who have led the business 
for decades, and continue to do so in their 
current roles, with full accountability for its 
operations and performance. At the same 
time they, and their employees, also benefit 
from being part of a large, international 
Group with the resources, networks and 
expertise that brings. The Peerless team was 
particularly excited about the opportunities 
to collaborate with Clarendon – seeing the 
complementary customer relationships and 
market exposure as strong growth drivers.
A strong start
Peerless has a market-leading reputation, 
built over decades. This, combined with its 
deep customer and supplier relationships 
and extensive inventory of high quality 
specialty fasteners, positions it well for 
continued growth. Peerless has a long track 
record of strong revenue growth and high 
operating margins. In the first five months of 
ownership, the business exceeded 
Diploma’s expectations as it leveraged its 
strong position and agility as a supplier in 
the complex aerospace supply chain. 
Peerless is an 
excellent acquisition 
for Diploma, aligned 
to our strategy of 
building high quality, 
scalable businesses 
for sustainable 
organic growth.

Organic revenue growth of 1% 
demonstrating resilient performance 
against a challenging market backdrop.
£90.7m
Adjusted operating profit of £90.7m, up 
15%, reflects the full-year contribution of 
DICSA, current year acquisitions and the 
impact of investments made in facilities, 
technology and talent to support future 
growth. 
Margin decline of 40 basis points reflects 
ongoing investment in the segment to 
better position for future growth. 
I am pleased with our resilient 
performance against a tougher

SEALS
TED MESSMER 
CEO, NORTH AMERICAN  
SEALS
International Seals 
(54%1 of Seals Sector revenue) was resilient, 
delivering organic revenue growth of 1%. 
Strong growth in Australia mitigated the 
impact of the challenging market backdrop 
in Europe. The Sector continues to expand 
into markets that are structurally growing 
and that benefit from sustained investment. 
We made a number of quality acquisitions in 
the UK in the year, extending product range, 
expanding end markets and further 
penetrating the UK. Investment in facilities, 
technology and talent in the year positions 
the Sector well for FY25. 
North American Seals 
(46%1 of Seals Sector revenue) delivered 
organic growth of 1%, despite contraction in 
the US manufacturing market. Solid growth 
in the core aftermarket repair segment 
mitigated the impact of reduced activity 
across OEM and some aftermarket reseller 
customers. Performance in the year was 
driven by new contract wins, product 
extension and expansion into end markets 
including energy, water, and hydraulics. 
Investment in talent and technology in the 
year will support future growth. 
Revenue diversification driving  
organic growth
In challenging market environments, the 
quality of our Seals portfolio has shone 
through with a resilient revenue 
performance. In International Seals, Diploma 
Australia Seals delivered strong growth as its 
value-add customer proposition drove share 
gains in markets benefitting from sustained 
infrastructure investments as well as 
continuous strong demand for the mining  
of the minerals required for batteries for 
energy storage. Our UK fluid power 
business, R&G, was impacted by delays to 
infrastructure projects in the mining, rail,  
and naval sectors. 
M Seals delivered a strong second half, 
securing new contract wins for projects in its 
Nordic markets. As expected DICSA, our 
Spanish fluid power business acquired in 
FY23, delivered modest growth reflecting 
destocking in the first half of the year  
and the ongoing challenging backdrop  
in Europe. 
In North American Seals, VSP delivered very 
strong organic growth across all its core 
markets in the year. This performance was 
supported by new contract wins in the 
transportation market, product extension  
to broaden the range available to industrial 
customers, and cross-selling opportunities 
arising from prior year acquisitions.

Capital discipline
Continuing our disciplined approach to 
portfolio management, in October 2024, 
we made two disposals in the Seals Sector: 
Kubo, a Swiss OEM-focused business, and 
Pennine Pneumatics, a UK business, which 
was part of R&G. Kubo, which was sold for 
ca. £28m, has a strong value-add 
proposition but requires increased vertical 
integration to support future growth. 
Pennine, with a less-scalable proposition, 
was sold for ca. £12m to its largest supplier.  
Outlook
The Seals Sector remained resilient and 
continued to grow through difficult trading 
conditions in FY24. This is testament  
to the diversification of the portfolio  
and the strength of our value-add  
customer propositions. 
Whilst customer activity remains cautious, 
we expect a stronger performance in FY25 
in both our International and North American 
Seals businesses. We anticipate a 
resumption of investment across 
infrastructure and industrial end markets in 
the US, the UK and Europe following a 
recent period of uncertainty in many 
countries in which we operate.
Having invested in our businesses in our 
North America and International Seals 
businesses throughout FY24, they are well 
positioned to drive stronger growth as 
market conditions improve.
Building scale
During a period of slower growth, we have 
taken the opportunity to invest in our Seals 
businesses to build a stronger platform from 
which to grow when the trading environment 
improves. Across the Sector, we have 
invested in talent to strengthen and develop 
areas including sales and supply chain 
management. In Hercules Aftermarket, we 
have also enhanced our digital platforms 
and customisation capabilities. We also 
undertook a restructuring project to better 
position the Sector for growth.
Significant investments in facilities in 
International Seals are important steps on  
M Seals’ and R&G’s scaling journeys. M Seals 
opened its new state-of-the-art facility in 
Denmark, creating a Nordic hub for the 
Sector, providing improved warehousing 
capabilities and a wide range of value-add 
services to support future growth. In the UK, 
R&G created a National Distribution Centre 
in Lincoln as the main stocking location for 
its Hydraulics businesses and also 
introduced a hose assembly Centre of 
Excellence in Liverpool. In Diploma Australia 
Seals, an integration project to combine 
three previously standalone businesses into 
one has been successful and provides a 
solid platform to further build on the strong 
performance of this business.   
Targeted acquisitions to accelerate growth
During the year, four new UK businesses 
were welcomed into R&G, expanding end 
market exposure, extending our product 
range, and penetrating the UK market  
more widely. 
PAR Group significantly expands our 
aftermarket seals & gaskets capabilities 
in the UK and further diversifies R&G’s 
customer base and end market exposure. 
The acquisition presents strong opportunities 
for organic growth, synergies and cross-
selling. Fast Gaskets is a distributor of 
soft gaskets and rubber sheets, and is 
an approved supplier to the UK defence 
industry. PTFE Flex is a specialist solution 
provider into the food & beverage, 
pharmaceutical, and chemical end markets. 
Abbey Hose, a specialist hydraulic and 
industrial hose distributor, extends R&G’s 
geographical reach within the UK and 
creates access to key infrastructure 
projects and customers. 
Our new M Seals facility, which 
opened in January this year, creates  
a Nordic hub for the Seals Sector.

FINDING SOLUTIONS TO 
COMPLEX CHALLENGES 
THE CHALLENGE 
•	 Diploma Australia Seals’ customer – a 
bulk sand supplier – faced suppressed 
production capability, high overhead 
costs and non-compliant processes
THE SOLUTION
•	 Customer approached DAS business, 
FITT Resources
•	 Drawing on technical product expertise, 
they designed a new solution and 
leveraged exclusive distribution rights 
to deliver it to the customer
THE OUTCOME
•	 Customer more than doubled output, 
reduced overheads and complied with 
council-enforced operating restrictions
Diploma Australia Seals (DAS) specialises 
in the supply of premium mechanical 
engineering products, parts and servicing 
for a range of industrial applications. 
They work closely with their customers to 
understand their challenges, build solutions 
that save their customers cost and improve 
reliability, efficiency and safety. 
The challenge 
DAS business, FITT Resources, was 
approached by a bulk sand supplier 
operating their own quarry on the Gold 
Coast. The customer was using a dredge to 
transport sand from their quarry pond to a 
processing plant located 1km away. The 
dredge they were using was inefficient, 
labour intensive to operate, and didn’t 
comply with council-enforced noise and 
operating limits. Furthermore, it struggled  
to maintain production of 150,000 tonnes  
of sand per year. 
The solution 
FITT Resources was able to draw on its 
in-house expertise on product and 
application use to design the right dredge 
solution for the customer. Importantly, 
they were able to leverage their exclusive 
distribution agreement for Australia and 
New Zealand with a global dredge supplier. 
The outcome 
The package system FITT Resources 
designed and delivered for the customer 
comprised a dredge with a pump and GPS 
automation, which supports remote and 
autonomous dredge operation and allows 
for consistent and continuous flow of 
product to the process plant. 
Importantly, the ability to operate the 
dredge remotely from a centralised control 
significantly reduces health and safety risk 
as operators are no longer required to enter 
high-risk zones.
The new system allowed the customer to 
more than double their annual production 
of sand to over 330,000 tonnes, and 
reduce their overheads as a result of 
the autonomous capability. Overall, the 
customer achieved a 50% per tonne 
reduction in operational costs. 
Finding solutions 
to our customers’ 
challenges is what 
we’re here to do.

We’ve made great progress and 
the Sector is well positioned to 
build on the good momentum 
of the last two years. 
Revenue diversification driving 
organic growth
Life Sciences North America delivered 
impressive double-digit revenue growth at 
the same time as implementing a significant 
scaling project. This strong performance 
was driven by the continued adoption and 
implementation of new technologies by 
hospitals within the urology, gynaecology 
and endoscopy specialties creating 
opportunities to broaden our product 
range and grow market share in the 
medtech space. In in vitro diagnostics 
(IVD), we are supporting further adoption 
of automated solutions, reflecting the 
increased investment and growth in IVD 
testing in the Canadian market. 
Leveraging the benefits of our integrated 
business in Life Sciences Australasia, 
following scaling investment in the prior 
year, we have delivered double-digit growth. 
Our new integrated platform has supported 
growth in IVD. We have extended our 
proposition in allergy and autoimmunity 
testing to existing customers, and 
benefitted from growing demand 
for genetic preconception screening, 
which is being supported by increased 
government funding. 
In Life Sciences Europe, we have 
restructured and rationalised our portfolio 
as we seek to build a more scalable and 
sustainable model in this geography. This 
project has resulted in a slight reduction in 
revenue year on year despite continued 
growth in IVD and critical care portfolios in 
the UK and Ireland, and tender wins in the 
Nordics. We have already seen improved 
margins as a result of the action taken to 
optimise the portfolio. 
Targeted acquisitions to  
accelerate growth 
The latest acquisition, GM Medical, which 
was brought into the Sector in FY23, 
performed very well during the year and 
was successfully integrated into our Nordics 
platform, extending its product portfolio.
We have a strong pipeline of acquisition 
opportunities in Life Sciences across our 
geographies, with a number of bolt-ons 
currently being evaluated.

Following a successful scaling project 
in Australia in FY23, a project of similar 
significance was undertaken in Canada 
during the year, rationalising existing sites 
in the East of the country and forming two 
distinct East and West hubs. This large-scale 
project provides the right platforms to 
further enhance the already high levels of

ultimately improving patient care outcomes. 
The new facility in Mississauga, Ontario, 
provides a more scaled and strategically

Outlook
The Sector is well positioned to build on 
the good momentum of the last two years, 
with favourable market dynamics and the 
benefits from our continuing scaling 
investments and portfolio rationalisation. 
We expect another strong year in FY25.

CANCER PATIENTS IN AUSTRALASIA
THE CHALLENGE 
•	 Lung carcinoma is the most common 
cause of death worldwide
•	 The most common form of lung cancer 
is often late-diagnosed
•	 The existing diagnostic test required an 
invasive tumour sampling procedure 
and took up to 18 days from sampling 
to initiation of treatment 
THE SOLUTION
•	 Life Sciences Australasia business, 
Abacus dx, brought new technology to 
market
THE OUTCOME
•	 Fully automated, less invasive test that 
delivers results within 2.5 hours
•	 Reduced time from sample to 
treatment to 1-2 days
SECTOR REVIEW: LIFE SCIENCES  
CASE STUDY CONTINUED
Our Life Sciences businesses work 
alongside healthcare practitioners to 
navigate a complex regulatory 
environment and deliver innovative, 
market-leading solutions that improve 
patient outcomes.
The challenge 
Lung carcinoma remains the most 
common cause of cancer death 
worldwide. Nearly 85% of lung cancers 
are non-small cell lung cancer. This is 
often diagnosed at an advanced and 
metastatic stage. As a result, the 
prognosis of patients with this type of 
lung cancer remains poor, with average 
five-year survival rates at ca. 16%.
Existing market-standard diagnostic 
methods meant that it could take over 18 
days between tumour sampling and 
initiation of treatment. 
The solution 
Our Life Sciences Australasia business, 
Abacus dx, has worked closely with an 
existing supplier to bring a new diagnostic 
technology to the Australasian market, 
which significantly reduces the time from 
biopsy to diagnosis, improving patient 
survival rates.
The outcome 
The fully automated test brought to market 
by Abacus dx delivers results within 2.5 
hours, reducing the time between sample 
to treatment to one or two days. Requires 
under two minutes of ‘hands-on’ time, and 
it is significantly less invasive than existing 
testing methods. 
The test also avoids the challenge of 
obtaining samples of sufficient size and 
quality, encountered with traditional 
testing, by requiring a significantly  
smaller sample. 
The value we deliver  
Abacus dx has demonstrated its value to 
patients across Australia and New Zealand, 
its customers, and its supplier in bringing 
this product to market.
Laboratories and hospitals have assurance 
of a steady and reliable supply of reagents 
for this urgent and much needed test,  
and have access to ongoing support in  
the repair and maintenance of the  
testing platform. 
In addition to providing suppliers with an 
efficient route to market, Abacus dx 
promotes the product nationally, 
publishing articles about the testing 
platform and engaging key opinion leaders 
and medical experts to raise awareness of 
faster testing at scientific and oncology 
conferences. All of these actions result in 
better outcomes for cancer patients.
HEADQUARTERS
The innovative 
solutions we bring 
to market can really 
be life changing – 
and sometimes life 
saving – for 
patients.

Financial Statements

The Group reports under UK-adopted International 
Accounting Standards (UK-adopted IAS) and references 
alternative performance measures where the Board 
believes that they help to effectively monitor the 
performance of the Group and support readers of the 
Financial Statements in drawing comparisons with past 
performance. Certain alternative performance measures 
are also relevant in calculating a meaningful element of 
Executive Directors’ variable remuneration and our debt 
covenants. Alternative performance measures are not 
considered to be a substitute for, or superior to, 
UK-adopted IAS measures. These are detailed in 
note 29 to the consolidated financial statements.
£4.4m (2023: £5.9m) of fair value 
adjustments to inventory acquired through 
acquisitions recognised in cost of 
inventories sold; £10.2m of acquisition 
related expenses (2023: £6.3m) and £3.6m 
of restructuring costs (2023: £nil). There 
were no disposals during the year, whilst  
the prior year included a £12.2m net gain  
on disposals.
Acquisition related finance charges include 
fair value movement and the unwind of 
discount on acquisition liabilities of £3.2m 
charge (2023: £0.4m charge); £0.9m charge 
(2023: £5.9m charge) for the amortisation 
and write-off of capitalised borrowing fees 
on acquisition related borrowings; fair value 
remeasurements of put options for future 
minority interest purchases of £0.1m income 
(2023: £1.8m charge); and net income from 
interest and settlement of acquisition  
and disposal related items of £0.2m  
(2023: £0.8m net income). 
The Group’s adjusted effective rate of 
tax on adjusted profit before tax was 24% 
(2023: 24%). The Group’s tax strategy was 
approved by the Board and is published  
on our website. 
Adjusted earnings per share increased by 
15% to 145.8p (2023: 126.5p). Basic earnings 
per share increased by 6% to 96.5p (2023: 
90.8p) reflecting the profit on disposal in  
the prior year.

Reported revenue increased by 14% to 
£1,363.4m (2023: £1,200.3m), driven by 
organic growth of 6% and a 10% 
contribution from acquisitions, partly  
offset by adverse movements in foreign 
exchange translation. 
Adjusted operating profit increased by 
20% to £285.0m (2023: £237.0m) as the 
operational leverage from the increased 
revenue, disciplined cost management and 
accretive acquisitions drove a year-on-year 
improvement of 120 basis points in the 
adjusted operating margin to 20.9% (2023: 
19.7%). Statutory operating profit increased 
13% to £207.4m (2023: £183.3m), with prior 
year benefitting from an exceptional £12.2m 
profit on disposal of Hawco.  
Adjusted net finance expense increased to 
£27.0m (2023: £20.4m), principally due to 
higher average gross debt as all acquisitions 
in the year were debt funded. The blended 
cost of all bank debt marginally decreased 
to 5.3% largely due to the issuance of 
£319.8m of private placement notes  
(2023: 5.6%). 
Adjusted profit before tax increased 19% 
to £258.0m (2023: £216.6m). 
Statutory profit before tax was £176.6m 
(2023: £155.6m) and is stated after charging 
acquisition and other related charges. The 
adjustments to operating expenses made in 
relation to acquisition related and other 
charges total £77.6m (2023: £53.7m) 
comprised of £59.4m (2023: £52.9m) of 
amortisation of acquisition intangible assets;

FINANCIAL REVIEW

Net capital expenditure was lower this year 
at £14.0m, primarily consisting of £19.7m 
investment in new field and demo 
equipment and a premise move in Life 
Sciences as well as ongoing investments 
in plant and equipment across the Group, 
partly offset by £5.7m of disposals which 
were largely property related. 
The Group funded the Company’s Employee 
Benefit Trust with £2.3m (2023: £1.9m) in 
connection with the Company’s long term 
incentive plan.
Acquisitions accelerate growth
Net cash flow from acquisitions of £311.0m 
(2023: £255.3m) included £270.5m of cash 
paid for the acquisitions of Peerless, PAR 
Group and five smaller bolt-ons; £11.3m of 
acquisition related deferred consideration 
paid and £30.2m of acquisition related 
costs, partly offset by £1.0m received in 
relation to the disposal of Hawco in the  
prior year.
The Group’s liabilities to shareholders of 
acquired businesses at 30 September 2024 
was £25.4m (2023: £22.6m) and comprised 
both put options to purchase outstanding 
minority shareholdings and deferred 
consideration payable to vendors of 
businesses acquired during the current  
and prior years. 
Interest payments reduced by £0.5m to 
£17.4m (2023: £17.9m) driven largely by the 
change in interest payment profile on the 
private placement notes during the year.  
Tax payments increased by £17.0m to 
£58.4m (2023: £41.4m) with the cash tax rate 
increasing to 23% (2023: 19%), mainly due  
to timing of payments in the US and the 
increase in the UK corporation tax rate.  
Our effective cash tax rate remains lower 
than our Group effective tax rate, mainly  
due to tax deductible acquisition goodwill  
in the US. 
Depreciation and other non-cash items 
includes £32.2m (2023: £28.6m) of 
depreciation and amortisation of tangible, 
intangible and right of use assets and  
net £1.2m (2023: £1.9m) of other  
non-cash items, primarily share-based  
payments expense. 
Working capital increased by £8.5m 
in support of business growth. 
Recommended dividend
The Board has a progressive dividend policy 
that aims to increase the dividend each year 
by 5%. In determining the dividend, the 
Board considers a number of factors which 
include the free cash flow generated by the 
Group, the future cash commitments and 
investment needed to sustain the Group’s 
long-term growth strategy.
For FY24, the Board has recommended a 
final dividend of 42.0p per share, making  
the proposed full year dividend 59.3p  
(2023: 56.5p). 
Strong cash flow
Free cash flow increased by 21% to £197.9m 
(2023: £163.8m). Statutory cash flow from 
operating activities increased by 9% to 
£279.7m (2023: £257.3m). Free cash flow 
conversion for the year was 101% (2023: 
100%), ahead of the 90% in our financial 
model, demonstrating the highly cash-
generative qualities of our businesses and 
the results of targeted inventory reductions.

(Gremtek) as held for sale under IFRS5. All 
three disposals were completed on 31 
October 2024, with total consideration (on a 
cash-free and debt-free basis) of  
ca. CHF31.3m (ca. £28.1m) for Kubo,  
ca. £12.0m for Pennine and ca. €5.5m  
(ca. £4.6m) for Gremtek. No gain or loss was 
recognised in the Consolidated Income 
Statement on classification of the above 
assets and liabilities held for sale.
Dividends of £77.2m (2023: £70.8m)  
were paid to ordinary and minority  
interest shareholders.
Attractive returns
Return on adjusted trading capital employed 
(ROATCE) is a key metric used to measure 
our success in creating value for 
shareholders. It is a metric that drives 
ongoing capital and operating discipline, 
adding back amortised intangibles and 
other factors such as any impaired goodwill 
such that any improvement must be driven 
by true economic factors. As at 30 
September 2024, the Group’s ROATCE 
increased by 100 basis points to 19.1% 
(2023: 18.1%). This increase was driven by 
strong operating profit growth from the 
existing businesses and accretive 
acquisitions completed during the year 
which is expected to generate year one 
returns in excess of 20%.
now contractually due to expire across July 
2028 (£40.0m) and July 2029 (£515.0m). A 
24-month extension option in respect of 
£40.0m and a second 12-month extension 
option in respect of £515.0m can be 
exercised in July 2025. At 30 September 
2024, the Group had utilised £165.1m of the 
RCF (2023: £320.9m), with £389.9m of the 
revolving facility remaining undrawn.
At 30 September 2024, net debt of £419.6m 
(2023: £254.7m) represented leverage of 
1.3x (2023: 0.9x) against a banking covenant 
of 3.5x. The Group maintains strong liquidity, 
with year-end headroom (comprised of 
undrawn committed facilities and cash 
funds) of £450m (2023: £297m). The table 
below outlines the composition of the 
Group’s net debt at 30 September 2024:
•	 The liability to acquire minority 
shareholdings outstanding relates to a 
10% interest held in M Seals; 5% interest in 
Techsil; a 2% interest in R&G; and a 5% 
interest in Pennine Pneumatic Services 
(disposed of subsequent to the period 
end, as noted below). These options are 
valued at £9.0m (2023: £9.2m), based on 
the latest estimate of EBIT when these 
options crystallise.
•	 The liability for deferred consideration 
payable at 30 September 2024 was 
£16.4m (2023: £13.4m). This liability 
represents the best estimate of any 
outstanding payments based on the 
expected performance of the relevant 
businesses during the measurement 
period. The increase in the year is primarily 
due to the addition of Peerless and PAR 
Group deferred consideration and 
revaluation increases, somewhat offset by 
payments made in the year. 
Goodwill at 30 September 2024 was 
£541.1m (2023: £439.1m). Goodwill is 
assessed each year to determine whether 
there has been any impairment in the 
carrying value. It was confirmed that there 
was significant headroom on the valuation 
of this goodwill, compared with the carrying 
value of the related Cash Generating Units at 
the year end. 
As at 30 September 2024, the Group 
classified the assets and liabilities of Kubo 
Tech AG and its subsidiary Kubo Tech GmbH 
(Kubo); Pneumatic Services Limited and its 
subsidiary Pennine Pneumatic Services 
Limited (Pennine); and Gremtek SAS 
Improved funding
At 30 September 2024, the Group’s net 
debt stood at £419.6m (2023: £254.7m). 
During the year, the Group issued US private 
placement notes for an aggregate principal 
amount of £207.9m (€250.0m) with 
maturities of 7 years (€75m), 10 years 
(€100m) and 12 years (€75m) and for an 
aggregate principal amount of £111.9m 
($150.0m) with maturities of 8 years ($100m) 
and 11 years ($50m).
The Group has a multi-currency revolving 
credit facility agreement (RCF) with an 
aggregate principal amount of £555.0m. In 
July 2024, the Group exercised the first of 
two 12-month extension options for the RCF, 
which was accepted by banks committing 
£515.0m of the aggregate total. The RCF is

be reviewed for its relevance to the Scheme. 
As the Court of Appeal has only just 
delivered its verdict, the Scheme pension 
advisors have not yet completed any 
analysis and therefore no adjustments have 
been made to the Consolidated Financial 
Statements as at 30 September 2024. 
In Switzerland, local law requires our Kubo 
business to provide a contribution-based 
pension for all employees, which is funded 
by employer and employee contributions. 
The cash contribution to the scheme was 
£0.5m (FY23: £0.5m). The pension deficit in 
the Swiss scheme was £1.0m (FY23: £0.3m) 
and formed part of the liabilities held for 
sale as at 30 September 2024. 
Exchange rates
A significant proportion of the Group’s 
revenue (ca. 80%) is derived from 
businesses located outside the UK, 
principally in the US, Canada, Australia and 
continental Europe. Compared with FY23, 
the average Sterling exchange rate is 
stronger against most of the major 
currencies in which the Group operates and 
the impact from translating the results of the 
Group’s overseas businesses into UK sterling 
has led to a decrease in Group revenues of 
£34.4m and a decrease in the Group’s 
adjusted operating profit of £8.5m.  
The impact to net debt is a reduction of 
£26.0m when compared with prior year 
closing rates. 
Accordingly, the Directors continue to have 
a reasonable expectation that the Group  
has adequate resources to continue in 
operational existence for the foreseeable 
future and continue to adopt the going 
concern basis in preparing the Annual 
Report and Accounts.
 
Pensions
The Group maintains a legacy closed 
defined benefit pension scheme (the 
Scheme) in the UK. In the year, the Group 
funded this scheme with cash contributions 
of £0.5m (2023: £0.6m). 
On 26 March 2024, the Trustees completed 
a Buy-In of the remaining pensioner 
liabilities in the Scheme with Just Retirement 
Limited. The Scheme paid £25.1m to Just 
Retirement Limited to fund 100% of the 
Buy-In premium. At 30 September 2024, the 
UK defined benefit scheme was in a surplus 
position of £1.5m (2023: £6.8m). As at 30 
September 2024, 94% of the scheme  
assets are concentrated in the Buy-In  
policy and we expect to make no further  
funding payments.
The Group is aware of a UK High Court legal 
ruling in June 2023 between Virgin Media 
Limited and NTL Pension Trustees II Limited, 
which decided that certain historic rule 
amendments were invalid if they were not 
accompanied by actuarial certifications. The 
ruling was subject to an appeal with a 
judgment delivered on 25 July 2024. The 
Court of Appeal unanimously upheld the 
decision of the High Court and concluded 
that the pre-April 2013 conditions applied to 
amendments to both future and past 
service. Whilst this ruling was in respect of 
another scheme, this judgment will need to 
Going concern
The Group’s business activities, together 
with the factors likely to affect its future 
development, performance and position are 
set out in this announcement and further 
detailed in the Annual Report and Accounts, 
which also includes an assessment of the 
Group’s longer term viability.
The Directors have undertaken a 
comprehensive review of going concern, 
taking into account the updated financing of 
the Group against a number of economic 
scenarios, to consider whether there is a risk 
that the Group could breach either its facility 
headroom or financial covenants.
The Group has modelled a base case and a 
severe but plausible downside case in its 
assessment of going concern. The base 
case is driven off the Group’s detailed 
budget which is built up on a business by 
business case and considers both the micro 
and macroeconomic factors which could 
impact performance in the industries and 
geographies in which that business 
operates. The severe but plausible downside 
case models steep declines in revenues and 
operating margins resulting in materially 
adverse cash flows. These sensitivities 
factor in a continued unfavourable impact 
from a prolonged downturn in the economy. 
Both scenarios indicate that the Group  
has significant liquidity and covenant 
headroom on its borrowing facilities to 
continue in operational existence for  
the foreseeable future.

expertise and in-depth knowledge. 
Engagement ensures we retain that 
valuable talent and experience and nurture 
the unique culture that binds the Group. 
We held our fourth Group Colleague 
Engagement Survey this year, achieving a 
response rate of 87% and index score of 
79% (FY23: 80%). Every business has an 
engagement plan to address the themes  
of their survey results. This is prioritised at 
every level of the business, and we have 
introduced engagement targets into our 
remuneration package for our Executive 
Team and Managing Directors for FY25.
Colleague turnover of 20% (FY23: 17.7%) 
was driven by facility moves in Life Sciences 
and Controls. 
Diversity, Equity and Inclusion
We continue to support diversity, equity 
and inclusion through educational events 
and initiatives, such as our Women in 
Leadership programme, inaugural Diploma 
Pride event and annual celebration of 
International Women’s Day. 
This was supplemented with more formal 
training for our Executive Team, which 
attended an inclusive leadership workshop. 
We also introduced an inclusive hiring toolkit 
for our businesses. Ethnic diversity 
increased to ca. 10% (FY23: 8%) for the 
Senior Management Team.

HEALTH AND SAFETY 
In order to align with industry standards, 
we have updated our leading metric to a 
lost time incident frequency rate (LTIFR), 
defined as total Lost Time Incidents (LTIs)
per 1,000,000 hours worked. 
In FY24, our LTIFR was 3.6. Driving 
meaningful change takes time and we have 
developed a more hands-on approach to 
H&S for acquisitions, including inductions 
for leadership, post-acquisition audits, 
colleague training and action plans. 
Despite an increase in total LTIs to 
23 (vs 18 in FY23), our total injury days 
decreased, resulting in a severity rate 
of 9.9 (vs 13.8 in FY23). We have also seen a 
strong improvement in both the quality and 
volume of potential hazard reporting, which 
has increased by 82% vs the prior year. 
It is encouraging that responses to this 
year’s Colleague Engagement Survey 
indicated an improvement in H&S culture. 
93% of colleagues agreed that H&S is 
taken seriously in their business vs 88% in 
the prior year. 
Although we have made strong strategic 
progress during the year, we remain 
focused on reducing our LTIFR rate. We will 
continue to drive our Stand Up for Safety 
programme across our businesses and 
senior management during FY25. We will 
also continue our audit programme, with 
external H&S audits planned for all 
businesses, including acquisitions.

Health and safety
Our Group health and safety (H&S) 
programme, Stand Up for Safety, covers 
four key areas: governance, leadership, 
training, and audits. This year, we engaged 
external experts, Safety Management 
Limited, to deliver masterclasses, training, 
and comprehensive audits at our key sites. 
Every business has an FY25 action plan to 
address the outcomes of their audits and 
risk assessments and we expect to see the 
impact of that during the year. 
Our Group-wide H&S network offers 
peer-to-peer support, best practices, 
resources and learnings. 
Supply chain management
We have surpassed our FY30 target and 
90% of key suppliers (accounting for >50% 
of supplier spend in aggregate) have agreed 
to comply with our Supplier Code. 
Charitable giving
Our fund matching programme ensures we 
give to the local causes that matter most to 
our businesses and colleagues. This year we 
donated ca. £134,000 (FY23: £54,000) to 
charity. No political donations were made.

We reduced waste to landfill to 23%

Our total operational emissions were down 
15% vs prior year and largely flat against 
our FY22 baseline. This is primarily due to 
the procurement of renewable energy, 
which now represents 44% of the Group’s 
energy consumption vs 7% in FY23.
We also undertook four facility 
consolidation and upgrade projects 
during the year and expect to see the 
benefit of those during FY25. In line 
with our strategy to increase our on-site 
renewable energy generation capacity, 
and through a combination of new builds 
and retrofitting, we have added 577kW to 
our solar coverage. Our emissions intensity 
decreased significantly from 7.6 in FY23 
to 5.7 this year.
Although we saw a reduction of 24% in 
Scope 3 emissions vs FY22 baseline, this 
was primarily due to better data and 
changes in emissions factors as we move 
away from cost-based calculations to 
primary data.

In January, our net zero targets were

initiative, covering Scope 1, 2 and 3. 
During the year, our businesses continued to 
effectively execute on our operational 
(scope 1 and 2) emissions strategy: 
understand, reduce, generate, procure. 
Scope 3 remains a complex challenge, 
especially in a decentralised environment. In 
calculating our FY23 footprint, we focused 
on educating and engaging our businesses 
with the most material emissions. 
Waste
Following a significant decrease in waste to 
landfill from 60% in FY22 to 32% in FY23, we 
have seen this taper off slightly, achieving 
23% waste to landfill in FY24, as we tackle 
the more challenging materials and 
geographies (US and Australia). This is great 
progress against our target of <15% waste 
to landfill by FY30.
Total waste has increased primarily due to 
the impact of acquisitions1. As a result, our 
waste intensity has also increased to 3.6 
(FY23: 3.3). We expect these to decrease  
as new businesses are brought into the  
DVR framework.

Our approach
Risk management and the oversight 
of appropriate systems of control 
are ultimately the responsibility of the 
Board, with responsibility for overseeing 
the effectiveness of the internal 
control environment delegated 
to the Audit Committee.
Group Internal Audit provides independent 
assurance that the Group’s risk management, 
governance and internal control processes 
are operating effectively. Each of our 
businesses is accountable for managing 
risks effectively. 
We have continued to broaden our 
risk management and governance 
by developing horizon scanning for 
emerging and potential risks, and 
enhancing efficiency of management 
and governance procedures.
Effective risk management is a 
key component of the discipline 
that underpins sustainable 
quality compounding.
Our risk management framework supports 
informed risk taking by our businesses. 
It sets out those risks that we are prepared 
to be exposed to and the risks that we want 
to avoid, together with the processes and 
internal controls necessary to evaluate the 
exposures and ensure they remain within 
our overall risk appetite.
This framework also provides the basis 
for the businesses to anticipate threats 
to delivering for their customers and 
ensures we are resilient to risks we have 
limited control over. 
Our governance processes continue 
to evolve in support of the Group’s 
strategic objectives. 
By improving our understanding and 
management of risk, we provide greater 
assurance to our shareholders, employees, 
customers, suppliers, and the communities 
in which we operate.

RISK MANAGEMENT AND INTERNAL CONTROL

Each of our businesses identifies risks 
and opportunities as part of their regular 
business reviews, evaluating how they 
are controlled, whether mitigations are 
appropriate and whether any further 
actions are required. 
The businesses use a quantitative 
framework to determine a score for 
each risk, which is based on both the 
likelihood and consequence of each risk 
occurring, and its impact on the business. 
Each risk is evaluated to provide a net score 
post-mitigation. This identifies which risks 
require internal mitigating controls, and 
which require further treatment. 
A similar exercise is then performed 
at Sector and Group level to develop an 
overall picture of operational risk for the 
Group. This process is both robust and 
challenging. It ensures that risks are 
identified and monitored and that 
management controls are embedded 
in the businesses’ operations.
During this process, the operational risks 
identified are reviewed to ensure there 
are no new principal risks or material risks 
affecting multiple businesses or Sectors. 
Any actions to improve evaluation or 
management of risks are shared across 
the businesses by the relevant Sector. 
Risk appetite 
The Board recognises that continuing 
to deliver resilient returns for shareholders 
and other stakeholders is dependent 
upon accepting a level of risk. 
Our risk appetite sets out how we balance 
risk and opportunity in pursuit of our 
strategic objectives. 
The acceptable level of risk is assessed 
on an annual basis by the Board, which 
defines its risk appetite against certain 
key indicators, including potential impact 
of risk, likelihood of risk and ability to reduce 
risk through mitigation. 
This ensures alignment between acceptable 
risk exposure and the strategic priorities 
of the Group.
We have three levels of risk appetite:
 Averse: take steps to avoid risk
 Cautious: take steps to mitigate risk
 Tolerant: accept risk
Identifying and monitoring material risks 
Material risks are identified through a 
detailed analysis of business processes 
and procedures and a consideration of 
the strategy and operating environment 
of the Group. 
With the assistance of the Audit Committee, 
the Board obtained assurance that the 
Group’s risk management and internal 
control framework was operating effectively 
and was therefore satisfied that risks were 
being managed in line with risk appetite. 
Risk management relies on internal control 
activities to ensure accurate accounting 
and to help mitigate the principal risks 
of the Group. 
The governance process within the 
framework ensures that the completeness 
of identified risks and adequacy of mitigating 
actions are appropriately reviewed by the 
Executive Team and are reported to the 
Board on a regular basis. 
Emerging risks and opportunities
The Board also considers potential risks and 
opportunities that could impact our Group 
in the future. 
The risk management framework enables 
early identification of emerging risks and 
opportunities so that they can be tracked and 
evaluated thoroughly at the appropriate time 
with any potential exposure assessed. This 
allows the Board to determine if the Group 
is adequately prepared for the situation. 
The most critical emerging risks under 
active consideration across the Group – 
Electrification and Disruptive Technology – 
remain the same as last year, and continue 
to be monitored. 
Electrification risk
Electric power substituting 
hydraulic power
The adoption of electric power over 
hydraulic power in various industrial 
applications may render certain seal 
applications redundant.
Electrification of industrial machinery
The widespread adoption of electrification 
in industrial machinery could alter existing 
maintenance regimes designed for internal 
combustion engines (ICE).
Disruptive technology risk
Step change in wireless infrastructure
Advances in wireless infrastructure could 
diminish the demand for wired connections 
by our wire and cable businesses.
Digitalisation of value-add
The increasing use of AI and other 
technologies facilitating the digitalisation of 
value-added services may provide customers 
with access to specialised knowledge 
currently provided by our businesses.
Mass availability of affordable 3D printing
The widespread availability of 3D printing 
technology could empower customers to 
produce their own bespoke component 
parts, potentially impacting some of our 
vertical integration processes.

RISK MANAGEMENT AND INTERNAL CONTROL CONTINUED

There have been several changes to the 
Group's principal risks during the year:
•	 Loss of key suppliers and supply chain 
disruption have been integrated into 
a single category. Given their closely 
related nature and shared characteristics, 
managing them together enables a more 
efficient approach, focusing on the 
interdependent challenges within the 
supply chain.
•	 The risk of failing to deliver major projects 
has been introduced. The growing number 
and complexity of change initiatives 
across the Group have amplified the 
challenges of successfully executing 
business and technology transformation 
programmes.
•	 Pandemic risk has been removed, 
as businesses now have more robust 
continuity and disaster recovery plans 
that address pandemics and similar 
disruptions. Additionally, new health 
and safety protocols have been integrated 
into operating procedures, eliminating 
the need to treat a pandemic as a 
separate risk.
•	 Cybersecurity risk has been downgraded 
from major to moderate consequence. 
While the threat of cyber incidents 
remains, our decentralised structure, 
enhanced security measures and 
strengthened risk management have 
collectively reduced the likelihood 
of severe impact.
The Group’s decentralised operating 
model helps mitigate the potential 
impact of our principal risks.
The Group risk matrix represents the risks 
and uncertainties faced by the Group, and 
steps taken to mitigate them. 
These risks, identified by the Board through 
a robust risk evaluation described on the 
previous page, are considered significant 
enough to have a material impact on the 
performance, position or future prospects 
of the Group.

RISK MANAGEMENT
In line with our decentralised model, each 
business unit addresses relevant risks, 
including environmental risks, in a way 
that fits their unique circumstances. With 
in-depth knowledge of their customers, 
industries, and products, our businesses 
are empowered to make local decisions 
and manage risks effectively.
Processes for identifying and 
assessing climate-related risks
We work with our businesses and Sector 
leadership to identify and evaluate all risks, 
including CRROs, drawing on expertise 
from relevant teams and Group functions. 
Business units identify and monitor material 
risks and CRROs, assessing controls, 
evaluating mitigations, and determining 
necessary actions. 
Environmental impacts, climate risks, 
and regulatory compliance for acquisition 
targets are also evaluated, with Sector and 
Group-level reviews conducted with Board 
oversight. This ensures alignment with our 
sustainability and strategic goals.
How we manage these Risks
We empower business units to manage 
CRROs and other risks locally using 
tailored mitigation strategies. 
Businesses use a quantitative framework 
that assigns scores based on likelihood, 
impact, and net effect post-mitigation. 
This prioritisation identifies which risks 
need further treatment or control measures.
Integration of these processes 
into overall risk management
At the Sector and Group-level, risks are 
consolidated to provide a comprehensive 
risk profile and a similar exercise is 
performed. 
The Group’s risk profile is reviewed with 
Board oversight to ensure alignment with 
strategic objectives. 
Scenario Analysis
In FY24, we revisited our qualitative scenario 
analysis to reassess the principal CRROs.  
The process was conducted internally, 
involving operational, business, and 
functional leaders across the Group. 
We use a probability-impact matrix to 
assess the likelihood of CRROs materialising 
over different timeframes and evaluate their 
potential impact and material significance 
to the Group. 
This assessment was conducted on a net 
basis, factoring in any mitigating measures 
or actions in place.

IDENTIFYING AND MANAGING RISKS ON 
PAGES 55-60
SCENARIO ANALYSIS  
PROBABILITY-IMPACT MATRIX
Short to medium-term risks
We consider risks material if they 
exceed 5% of the Group’s adjusted 
profit before tax, consistent with our 
Financial Statement audit methodology, 
in the year reflected in the latest long-
term strategic plan. 
'Short-term' covers risks up to 2030, 
while 'medium-term' encompasses 
risks from 2030 to 2040.
Long-term risks
For long-term risks, spanning 2040 to 
2050, we apply a materiality threshold 
twice that of short- to medium-term risks. 
This accounts for the Group’s expected 
growth, increased uncertainty over longer 
periods, and the time available to 
implement mitigation strategies.

STRATEGY
To effectively identify and assess 
CRROs, we analysed both physical 
and transitional climate scenarios. 
This assessment considered regulatory 
impacts, environmental changes at key 
locations, and shifting market dynamics 
that could affect our customer base and 
supply chain.
Recognising the importance of 
understanding future climate risks, we used 
Representative Concentration Pathways 
(RCPs) from the Intergovernmental Panel 
on Climate Change. These scenarios 
illustrate potential climate outcomes 
based on different levels of greenhouse 
gas emissions, allowing us to evaluate the 
impact of global warming on our business 
and strategic resilience.
CRROs identified over short, 
medium, and long terms
We identified two primary categories of 
CRROs; physical risks and transitional risks.
Physical risks: these include damage from 
extreme weather events, such as flooding, 
wildfires, extreme heat, and hurricanes, 
which can significantly disrupt operations 
and our supply chain. 
For example, our Hercules Aftermarket 
site has been identified as vulnerable to 
hurricane damage, prompting investment 
in targeted mitigation measures.
Transitional Risks:  
These involve regulatory changes and 
evolving customer expectations as 
economies transition to low-carbon models. 
Key concerns include the EU’s proposed 
ban on certain chemicals, such as PFAS, 
impacting our Seals businesses and 
increased carbon pricing affecting 
logistics costs. 
Additionally, our downstream market faces 
increasing scrutiny of emissions, requiring 
proactive adjustments in product offerings.
Impact of these CRROs on business, 
strategy, and financial planning
Our financial analysis indicates that 
the overall impact of these risks on our 
performance and viability is relatively low. 
Mitigating factors include our broad 
geographical footprint, a diversified 
customer and supplier base, and strong 
risk management strategies. However, 
we remain vigilant, recognising the 
potential for regulatory and market 
shifts to influence future operating 
costs and market competitiveness.
Strategy resilience under various 
climate scenarios
Our decentralised model strengthens 
our ability to adapt quickly to market 
and regulatory changes.
Local teams leverage their in-depth 
knowledge of customers, suppliers, and 
market conditions to implement effective 
risk management and resilience strategies
Key initiatives include supplier engagement, 
targeted decarbonisation efforts, organic 
growth in low-carbon markets, and value-
add services to absorb potential cost 
impacts from decarbonisation.
Scenario: fossil-fuelled growth
This scenario envisions limited global 
decarbonisation, leading to a 4°C 
temperature increase by 2100, consistent 
with RCP 8.5. The result is more severe 
and frequent weather events.
Impact Assessment: 
We conducted a risk assessment of 
10 critical sites, representing ca. 50% 
of our revenue, focusing on vulnerabilities 
such as flooding, wildfires, and hurricanes. 
We have implemented comprehensive 
disaster recovery plans, including 
insurance and physical safeguards, 
to mitigate these risks. 
Despite the increased frequency of 
extreme weather events, our diverse 
geographical presence and proactive 
risk management strategies help minimise 
financial disruption.
Scenario: steady path to sustainability
This scenario assumes coordinated global 
efforts to limit temperature rise to 2°C, in 
line with RCP 2.6, and achieving net zero 
by 2050.
Impact Assessment: 
We evaluated regulatory and market 
impacts on our operations, including 
potential cost increases from stricter 
environmental standards. 
Our analysis highlights the need for 
ongoing investment in low-carbon 
technologies and supply chain 
decarbonisation. 
Opportunities from this transition 
include expanding our product offerings 
in renewable energy markets and circular 
economy initiatives.

As a global company, we face evolving environmental 
regulations across key markets. A significant risk is the EU’s 
proposed ban on PFAS, impacting our Seals businesses, 
where around 6% of our revenue comes from PFAS-
containing products. Additionally, there is increasing 
pressure to decarbonise our products to align with 
customer sustainability demands.
KEY RISKS
Fragmented regulations could increase costs and 
reduce product competitiveness in regions with strict 
environmental standards.
The EU’s PFAS ban may lead to higher raw material 
costs and limited market access, impacting revenue.
Inability to decarbonise products may restrict access 
to markets prioritising low-carbon solutions, reducing 
competitiveness.
MITIGATION
Knowledge sharing: we share best practices across 
the Group to navigate regulatory changes, using insights 
from businesses experienced with stricter rules.
Supplier collaboration: our decentralised model enables 
strong supplier relationships, ensuring quick adaptation 
to new regulations. Our North American Seals business, 
for instance, has already developed PFAS-free products.
Proactive measures: we prioritise high-risk material 
identification, supplier engagement for accurate 
emissions data, and training to meet regulatory 
expectations, ensuring we stay ahead of compliance 
and remain competitive.
The global shift toward decarbonisation could increase 
operating costs, particularly for inventory procurement 
and logistics. This is driven by tightening environmental 
laws, such as carbon taxes, fuel levies, and emissions 
trading schemes. Logistics expenses, accounting for 
around 26% of our Scope 3 emissions, are especially 
vulnerable to these changes.
KEY RISKS
New regulations, like the EU’s Carbon Border Adjustment 
Mechanism (CBAM), could increase product and raw 
material costs.
Carbon taxes and investments in low-carbon technology 
could raise logistics and operational expenses.
Government emissions mandates may add further cost 
pressures, affecting profitability.
MITIGATION
Cost management: We mitigate rising costs by passing 
them to customers where feasible and improving 
operational efficiency.
Sustainable investments: Collaborate with logistics 
partners to adopt low-carbon freight options and 
cost-effective sustainable practices.
Regulatory engagement: Actively engage with 
policymakers to stay ahead of new regulations 
and adapt quickly to minimise financial impact.

Resilience of the Organisation’s Strategy
Our strategy is designed to stay resilient to 
Climate-Related Risks and Opportunities 
(CRROs) through several key measures:
Decentralised Model: Empowers our 
businesses to leverage deep product 
knowledge and strong local relationships, 
enabling swift adaptation to regulatory, 
market, and technological shifts.
Risk Diversification: Low reliance on 
individual customers and suppliers 
ensures broad risk coverage.
Cost Absorption: Value-added services 
and disciplined pricing protect margins 
from decarbonisation costs.
Organic Growth: Focus on emerging 
opportunities in the low-carbon 
economy to reduce exposure to 
high-carbon markets.
DVR Alignment: Comprehensive 
integration of our decarbonisation, 
value creation, and resilience (DVR) 
framework ensures all business units 
are aligned with our net zero goals.
Flexible Model: Our low capital intensity 
provides the agility needed for a smooth 
transition with minimal risk to asset values.
In July 2024, we strengthened our 
commitment to sustainability by updating 
our Supplier Code of Conduct and 
Environmental Policy. The new policies 
emphasise reducing greenhouse gas 
emissions, waste, and landfill use, while 
setting science-based targets. We’ve 
introduced initiatives like green logistics 
and enhanced supplier engagement to 
ensure transparency and further progress 
toward our long-term climate goals.
METRICS AND TARGETS
Metrics used to assess CRROs
To effectively manage CRROs, we 
monitor and measure several key metrics. 
Central to our strategy is the reduction of 
absolute GHG emissions, which is crucial 
in achieving our net-zero target by 2045. 
Additionally, we track waste management, 
recognising its significance for operational 
efficiency and supporting a circular 
economy, even though it is not a major 
emissions source. Supplier engagement 
is also critical, as aligning our suppliers with 
our Scope 3 emissions targets is essential 
to our overall net-zero strategy and this is 
embedded in our Supplier Code.
Disclosure of Scope 1, 2, and 3 GHG 
emissions and associated risks
We are committed to significantly reducing 
our environmental impact and aligning with 
global climate goals. As part of our net-
zero ambition for 2045, we have clear and 
ambitious short-term targets. By FY2030, 
we aim to cut our absolute Scope 1 and 2 
GHG emissions by 50% and reduce our 
absolute Scope 3 emissions by 30%, using 
FY2022 as our baseline. These targets are 
aligned with the 1.5°C pathway, consistent 
with the latest climate science and the 
Paris Agreement.
Our long-term strategy aims to achieve 
a 90% reduction in  emissions across all 
Scope, 1,2 & 3 from our FY2022 baseline. 
The Science Based Targets initiative (SBTi) 
approved these targets in December 2023, 
validating our transparent and robust path 
toward carbon neutrality. 
	SEE PAGE 53 FOR KEY CLIMATE 
RELATED METRICS
Targets for managing CRROs,  
and performance against them
Our commitment to meeting and 
exceeding climate action requirements 
is evident in our structured approach. 
We have established science-based, 
near-term targets to ensure that our 
emissions reductions are impactful 
and aligned with global standards. 
The short-term goal of reducing Scope 1 
and 2 emissions by 50% and Scope 3 
emissions by 30% by FY2030 sets a clear 
path. For the long term, achieving a 90% 
reduction by 2045 underscores our 
dedication to a sustainable future.

 EMBEDDING STAKEHOLDER VIEWS,  
 GUIDED BY OUR PURPOSE
Our business strategy is shaped and 
informed by the views of our stakeholders 
and we have always believed that 
stakeholder engagement is vital 
to building a sustainable business.
Stakeholder engagement
The Board is committed to effective 
engagement with all stakeholders and 
has established a culture that ensures 
this commitment is adopted within our 
businesses. Directors consider the views 
and interests of a wide set of stakeholders 
and are conscious that expectations around 
our performance and contribution to society 
– from local to global – are both diverse and 
continuously evolving. 
Stakeholder interactions take place at 
all levels of the Group and an essential 
component of our strategy is that we 
recognise the value of autonomy and 
ensure that decisions are made at the 
appropriate level. 
The Board will sometimes engage directly 
with stakeholders on certain issues where 
appropriate to do so, but the decentralised 
nature of our Group and resultant 
distribution of our stakeholders mean that 
some stakeholder engagement is more 
appropriate at an operational level. 
Our governance framework delegates 
authority for local decision-making to 
the appropriate level within a defined 
set of parameters. This allows Sectors and 
businesses to take account of the needs of 
their own specific key stakeholders in their 
decision-making. Our strong management 
teams make decisions with a long-term view 
and to the highest standards of conduct in 
line with overarching Group governance. 
The Board receives and debates regular 
reports from the Executive Team, who in 
turn have continuing dialogue with Sector 
and business management, to help it 
understand and assess the impact of 
our business, and the interests and 
views of our key stakeholders. 
It also reviews strategy, financial and 
operational performance, as well as 
information covering areas such as key risks, 
and legal and regulatory compliance. All 
Group and subsidiary board papers must 
demonstrate that relevant stakeholder 
perspectives and needs have been 
considered as part of the decision-making 
process. As a result of these activities, the 
Board has an overview of engagement with 
stakeholders, and other relevant factors, 
which enable the Directors to comply 
with their legal duties under s172 of the 
Companies Act 2006 and therefore 
improve decision-making. 
Please see pages 81 to 83 for details on how 
the Board operates and the way in which the 
Board and its Committees reach decisions, 
including the matters we discussed during 
the year.
SECTION 172 
Section 172 of the Companies Act 2006 
requires the Directors to promote the 
success of the Company for the benefit 
of the members as a whole, having regard 
to the interests of stakeholders in their 
decision-making. 
In discharging their duties, each Director 
will seek to balance the interests, views 
and expectations of the various 
stakeholders, whilst recognising that 
not every matter will be equally relevant 
to each stakeholder nor every decision 
necessarily result in a positive outcome 
for all. Decisions will be consistent with 
Diploma’s purpose and ultimately 
promote the long-term success 
of the Group.
Shoal Group, Life Sciences Canada 
and M Seals Denmark completed the 
build of their brand new, state-of

Investing
We all play a role at keeping our 
colleagues safe at work. During May

Safety’ campaign across our business 
as part of our Group-wide drive to 
keep health and safety culture at the 
forefront of minds.

How stakeholder interests have 
influenced decision-making 
Decisions taken by the Board and its 
Committees consider the interests of 
our key stakeholders, the impacts of 
these decisions and the need to foster 
the Company’s business relationships 
with customers, suppliers and other 
stakeholders. The Board acknowledges 
that not every decision it makes will 
necessarily result in a positive outcome for 
all stakeholders and the Board frequently 
has to make difficult decisions based on 
competing priorities. By considering the 
Group’s purpose and values together with 
its strategic priorities and having a process 
in place for decision-making, Directors aim 
to balance those different perspectives.
Throughout this Strategic Report, the Board 
has sought to demonstrate how the views of 
our stakeholders are embedded in how we 
do business, guided by our clear purpose. 
Details of the matters considered by the 
Board during the year can be found on  
page 76. 
Set out overleaf are some examples of 
decisions made by the Board in the year.
Dividend 
One of the principal decisions considered 
by the Board over the year has been in 
relation to returning value to shareholders. 
The Board has adopted a progressive 
dividend strategy, which considers our 
shareholders’ expectations, the Company’s 
liquidity position, and the financial resources 
required to execute our strategy. 
Acquisitions 
Acquisition opportunities remain central 
to our strategy, but the Board is also mindful 
of their potential impact on our existing 
stakeholders. Throughout the year, the 
Board discussed and approved several 
new opportunities and projects across 
our Sectors. The Board receives detailed 
proposals from our CEO and Corporate 
Development team in respect of a potential 
acquisition to consider the long-term impact, 
allowing us to make careful investments in 
businesses that possess essential Diploma 
characteristics, particularly high-quality, 
value-add customer servicing distribution 
and great management teams. The Board 
balances the financial commitment required 
against the risks and anticipated return, 
the relative benefits of capital investment 
within existing businesses, potential cultural 
differences, local regulatory or community 
impacts as well as how it will be perceived 
by investors.

ENGAGEMENT WITH STAKEHOLDERS  
AND SECTION 172 STATEMENT CONTINUED

In accordance with the UK Corporate 
Governance Code, the Directors 
have assessed the viability of the 
Group over a three-year period to 
30 September 2027, which is a 
longer period than the 12-month 
outlook required in adopting the 
going concern basis of accounting.
A period of three years has been chosen 
for this assessment, having considered the 
speed and degree of change possible in key 
assumptions influencing the Group, as well 
as the speed of evolution of the footprint 
of the Group, which collectively limits the 
Directors' ability to predict beyond the 
period chosen reliably. Given the pace 
of change in the primary end segments in 
which the Group operates, the Directors 
believe that three years represents the most 
appropriate timescale over which to assess 
the Group’s viability. This timescale is 
consistent with the Board’s review of the 
Group’s strategy at which the prospects of 
each business are discussed. As part of this, 
assumptions are made regarding entering 
into new markets and geographies; about 
future growth rates of the existing 
businesses; and about the acceptable 
performance of existing businesses.
The Group’s KPIs have been subjected 
to sensitivity analysis that includes flexing 
a number of the main assumptions, namely 
future revenue growth, operating margins 
and cash flows as a consequence of 
adverse trading impacts arising from 
a downturn in the major end markets 
in which the businesses operate, supply 
chain disruption and climate related risks. 
The degree of severity applied in this 
sensitised scenario was based on 
management’s experience and knowledge 
of the Sectors in which the Group operates.
The results of flexing these assumptions, in 
aggregate to reflect a severe but plausible 
downside scenario, are used to determine 
whether additional bank facilities will be 
required during this period. The Group has 
significant financial resources including 
banking facilities as detailed on page 159. 
The Group also has a broad spread of 
customers and suppliers across different 
geographic areas and independent market 
sectors, often secured with longer-term 
agreements. The Group is further supported 
by a robust balance sheet and strong 
operational cash flows.
The Directors confirm that this robust 
assessment also considers the principal 
risks and emerging risks facing the Group, 
as described on pages 55-60, and the 
potential impacts these risks would have 
on the Group’s business model, future 
performance, solvency or liquidity over the 
assessment period. The Board considers 
that the diverse nature of the Sectors and 
geographies in which the Group operates 
acts significantly to mitigate the impact any 
of these risks might have on the Group.
The viability assessment considers severe 
but plausible downside scenarios aligned 
to the principal risks facing the Group where 
the realisation of these risks is considered 
remote, considering the effectiveness of the 
Group’s risk management and controls and 
current risk appetite.
A robust financial model of the Group is built 
on a business-by-business basis and the 
metrics for the Group’s key performance 
indicators (KPIs) are reviewed for the 
assessment period. 
In addition, the Group has also carried out 
reverse stress tests against the base case 
financial projections to determine the 
conditions that would result in a breach of 
financial covenant. The conclusion of this 
was that the conditions required to create 
the reverse stress test scenarios on revenue, 
operating margin and cash flows were so 
severe that they were deemed implausible.
The Directors therefore confirm that they 
have a reasonable expectation that the 
Group will continue to operate and meet its 
liabilities, as they fall due, for the next three 
years to September 2027. The Directors’ 
assessment has been made with reference 
to the resilience of the Group as evidenced 
by its robust performance since the 
Covid-19 pandemic, its strong financial 
position and cash generation, the Group’s 
current strategy, the Board’s risk appetite 
and the Group’s principal risks and how 
these are managed, as described in the 
Strategic Report.

DAVID LOWDEN
CHAIR
Dear Shareholder, 
It is with great pleasure that I 
present, on behalf of the Board, 
the Corporate Governance Report 
for the year ended 30 September 
2024. This report summarises 
how Diploma’s leadership and 
governance structures have 
supported Diploma over the year 
in seeking to achieve long-term 
sustainable success. 
Our governance practices have evolved over 
decades to instil confidence in our investors 
and create long-term value while enabling 
our entrepreneurial businesses to thrive. 
Alongside our financial success, our 
governance practices champion long-term 
sustainable growth, enabling accountability, 
transparency and ensuring our entire Group 
operates effectively and responsibly. 
Throughout the past year, we have 
continued to develop and embed our 
Delivering Value Responsibly (DVR) 
frameworks. Further information on our 
sustainability programmes can be found 
on pages 50-53. Insights from our DVR 
and governance developments have been 
used to inform steps taken by the Board, 
the Executive Team and our businesses to 
improve the efficiency of other systems 
and processes, with the goal of further 
empowering our colleagues, increasing 
agility and speed in execution and 
enhancing local accountability. 
Effective leadership and colleague 
engagement depends on a healthy, 
empowered and positive business culture. 
Diploma has a strong purpose, values, and 
cohesive cultural fundamentals that govern 
our actions and provide guidance across 
our varied businesses. The Non-Executive 
Directors were pleased to experience this 
in person during our visits this year to 
Windy City Wire in the US and R&G, 
Shoal Group, IS-Group and Clarendon 
Specialty Fasteners in the UK.
Board succession
With the recently announced new 
appointments to the Board, I am confident 
that Diploma will continue to have the 
effective and resilient leadership required 
to fulfil our long-term growth ambitions. 
Janice Stipp joined us in January 2024 
and was appointed Chair of the Audit 
Committee in July 2024, succeeding Anne 
Thorburn, who stepped down from the 
Board in September 2024 after nine years. 
One area of focus was the review of our 
Committee compositions, reflecting the 
increased size and complexity of the Group. 
The following changes will take effect from 
1 January 2025. The Audit Committee will 
comprise Janice Stipp (Chair), Dean Finch, 
Katie Bickerstaffe and Ian El-Mokadem. 
The Remuneration Committee will comprise 
Jennifer Ward (Chair), Katie Bickerstaffe, 
Geraldine Huse and David Lowden. The 
Nomination Committee remains unchanged.
Looking ahead
The Board’s priorities for FY25 remain 
consistent, with a continued focus on: 
the implementation of the Group’s 
strategy; succession planning, managing 
risk and fostering an empowered and 
positive culture. 
Our AGM will be held on 15 January 2025. 
I hope that as shareholders in the Company, 
you will be able to attend to meet with the 
Board of Directors and discuss any matters 
you feel are important to the future success 
of the Group. I welcome the opportunity to 
meet with our shareholders at the AGM, but 
would also remind all stakeholders that the 
Board and I are available throughout the 
year to answer questions or engage on 
topics of interest to you. 
David Lowden
Chair
Additionally, Katie Bickerstaffe joined the 
Board as Senior Independent Director on 
1 October 2024, also succeeding Anne. 
Jennifer Ward, who joined the Board last 
year, has assumed the role of Chair of the 
Remuneration Committee, following the 
departure of Andy Smith in July 2024 after 
nine years on the Board. 
We announced in October 2024 that Ian 
El-Mokadem will be joining the Board in the 
first half of 2025. Ian brings with him a 
wealth of experience and expertise that will 
greatly contribute to the continued success 
of the Group. We look forward to welcoming 
him and working closely together in the 
coming year.
The Board recognises the value of diversity 
and inclusion, a key component of the 
Group’s DVR programme. Having recently 
completed a refresh of the Board, 
enhancing diversity in skillset, gender and 
ethnicity, we are confident that the Board is 
well-positioned for the future. Further 
information can be found in our Nomination 
Committee Report on pages 90-95.
Board evaluation 
This year, we undertook an externally 
facilitated evaluation of our Board 
and its committees. We engaged 
an independent firm, BoardClic, to 
ensure an objective perspective 
and actionable recommendations. This 
evaluation has also enabled the Board to 
identify opportunities for it to further 
improve its effectiveness; additional detail 
on the evaluation results and areas of 
agreed focus can be found on page 95.

DIVISION OF RESPONSIBILITIES

Successfully scaling up our value-add 
distribution model requires constant 
evolution, and our culture has a critical 
role to play in supporting growth.
The Board is responsible for ensuring that 
the Group achieves its purpose, which is 
to innovate, create and deliver value-add 
solutions for a better future. The 2018 UK 
Corporate Governance Code (the Code) 
emphasises the importance of the role of 
the Board regarding culture, with specific 
recommendations that the Board assesses 
and monitors. During the year, the Board 
has embedded and monitored culture in 
a number of ways. This includes business 
visits, presentations from Sector leadership, 
strategy review sessions, and updates  
on people and culture from the Group  
HR Director.
In reviewing the implementation of the 
Group’s strategy, the Board ensures that 
the objectives of our purpose are met 
whilst also taking into account the risks 
and opportunities facing the Group. For 
example, when considering acquisition 
strategies, cultural fit is an important area  
of focus and discussion. 
DIPLOMA PLC BOARD
The Board monitors and embeds culture through a variety of  
methods, including strategy updates, reports from the CEO,  
presentations by the Executives, Sector and functional leaders,  
employee engagement surveys, and site visits.
AUDIT COMMITTEE
Has oversight of internal controls and  
continuous access to external and internal audit,  
both of which can give an indication of culture, 
particularly honing in on any negative elements  
that don’t align with the Group’s culture.
REMUNERATION COMMITTEE
Receives updates from the Group HR Director that 
provide an overview of pay structures across the Group 
and their alignment with our purpose, values and strategy. 
This allows the Committee to ensure that the relevant 
policies and practices are consistent with our values.
EXECUTIVE COMMITTEE
Integrates our core principles into the Group's strategic framework, ensuring that every decision reflects  
our values. Regularly reviews Group's performance and strategy to identify areas of opportunity.
BUSINESS MDS
Ensures our core values and behaviours are reflected in every aspect of our operations, daily interactions and 
decision-making processes. Responsible for implementing engagement survey action plans for their respective 
businesses and monitoring progress against these plans.

GROUP VALUES AND BEHAVIOURS

BOARD SITE VISITS
Shared values and behaviours in 
a decentralised model 
Our decentralised model means that culture 
is embedded in our businesses, each of 
which has its own unique attributes. We 
believe this is critical to the accountability 
and empowerment that underpins the 
Group’s success. 
Whilst remaining decentralised and 
maintaining their own unique identity, 
our businesses also benefit from shared 
values; shared best practices, intercompany 
networks and exceptional leadership teams.
Employee engagement
The Board has considered the employee 
engagement methods specified by the 
Code but felt that alternative methods 
are more appropriate. Given the Group’s 
decentralised model and its geographical 
spread, the Board has continued with a 
multi-faceted approach to engagement 
with the global workforce that is not led by 
any one Director or group of Directors. 
We consider that engagement by the local 
Managing Directors (MDs) with their own 
workforce, together with strong channels of 
communication from MDs to their respective 
Sector CEO, as well as communication with 
the global workforce led by the Group’s 
central functions, provides an effective 
platform for transparent dialogue  
with employees. 
The Board feels well informed on colleague 
views and matters and uses a combination 
of methods to comply with the  
Code’s requirements:
•	 Updates to the Board at every 
scheduled Board meeting on people 
matters. Over the past year, colleague 
wellbeing and morale have been areas 
of keen focus.
•	 Colleague, talent and culture updates 
from the Group HR Director.
•	 The Remuneration Committee reviews 
workforce pay practices across Diploma.
•	 The Board regularly undertakes site visits. 
•	 Executive Board members regularly 
interact with individual businesses and 
our flat structure ensures strong channels  
of communication.
•	 The Board was presented with the 
outcomes of the Group Colleague 
Engagement Survey and discussed 
these together with key learnings. We 
were delighted with the high participation 
rate of 87% and engagement index score 
of 79%; the full results of the survey are 
detailed on page 51.
One of the ways the Board experiences and evaluates the culture is 
through meeting with colleagues across our businesses.
Visit to R&G in Lincoln
During a site visit to R&G in the UK in March 
2024, the Board engaged directly with 
employees and management to gather 
valuable insights that inform our strategic 
decisions. This provided a unique 
opportunity to understand the nuances 
of our workplace culture and employee 
engagement firsthand.
The Board gained a deeper appreciation 
of the challenges and successes 
experienced on the ground. The feedback 
obtained during this visit and other site 
visits throughout the year will play a role 
in shaping our policies and initiatives, 
ensuring our decision-making is aligned 
with the needs of our workforce.

Dear Shareholder 
I am delighted to write to you as the 
new Chair of the Audit Committee 
for Diploma. I was appointed to the 
Board in January 2024 and became 
Chair of the Audit Committee in July 
2024, and it is with great enthusiasm 
that I step into this role. 
The role of the Audit Committee is vital to 
ensuring the integrity and transparency of 
our financial reporting and internal controls, 
and I am fully committed to upholding the 
highest standards in these areas.
The Audit Committee assists the Board in 
discharging its responsibilities with regard 
to monitoring the integrity of Group financial 
reporting, external and internal audits, and 
controls. This includes advising on the 
reappointment and independence of 
external auditors and assessing the 
quality of their services; and reviewing the 
effectiveness and appropriateness of the 
Company’s internal audit activities, internal 
controls, and management systems. 
As part of the Group’s year-end reporting 
process, the Committee has thoroughly 
reviewed and challenged management's 
approach, analysis, and recommendations, 
incorporating the perspectives of the 
external auditor to finalise the Annual Report 
and Accounts. Additionally, the Committee 
has continuously assessed and monitored 
the Group's principal and emerging risks 
on an ongoing basis.
Long-term value 
creation is 
sustained by 
fostering a culture 
of integrity and 
transparency.
Throughout the year, we have dedicated 
significant time and resources to preparing 
for much-anticipated governance reforms. 
This involved continued development and 
implementation of our redesigned internal 
control framework, aimed at enhancing 
the robustness of our internal controls, 
audit processes, and financial reporting 
standards, ensuring greater transparency 
and accountability within the Group. 
Although the Government has decided to 
withdraw the secondary legislation that 
would have formalised some of these 
governance changes, they continue to move 
forward with plans to establish the Audit, 
Reporting and Governance Authority (ARGA) 
as the successor to the Financial Reporting 
Council (FRC). 
Looking forward, I am enthusiastic about the 
opportunities we have to further strengthen 
our governance practices and enhance our 
oversight functions. To that end, I am 
committed to engaging closely with our 
external audit partner to ensure a thorough 
and effective audit process and with our 
Head of Internal Audit to support a robust 
internal audit program. By maintaining an 
ongoing dialogue and alignment on audit 
priorities, we aim to identify and address any 
risks promptly and effectively, ensuring that 
our internal controls are not only effective 
but also continuously improving.
I am excited about the journey ahead 
and committed to working closely with all 
stakeholders to ensure Diploma remains 
well-positioned for continued success. 
I look forward to meeting shareholders 
at the AGM on 15 January 2025 and will be 
happy to respond to any questions relating 
to the activities of the Audit Committee.
Janice Stipp
Chair of the Audit Committee 
19 November 2024
In anticipation of these changes, we have 
proactively continued our internal planning 
efforts, ensuring that we are well-positioned 
to meet the new compliance requirements 
when they come into effect. This will remain 
a recurring item on the Committee’s agenda 
in the coming year, as we work to embed 
this into our operational framework.
As Audit Chair, I am committed to having 
regular conversations with the Group CFO, 
Group Head of Internal Audit, Group 
Financial Controller, Group Company 
Secretary & General Counsel and also the 
audit partner at PricewaterhouseCoopers 
LLP (PwC), our external auditor. PwC has 
now completed its seventh full annual cycle, 
with Richard Porter leading since FY23. 
I am pleased to report that again there have 
been no significant control deficiencies or 
accounting irregularities reported to the 
Committee this year. 
The Committee plans to commence a 
retender process for the audit during FY27 
for the FY28 Annual Report and Accounts 
in order to make any necessary changes to 
providers of other services in a timely and 
orderly fashion and to appoint an auditor 
before the start of that year, which is in the 
best interests of our shareholders. I am 
confident that the Audit Committee has 
carried out its duties effectively and to a 
high standard during the year, providing 
independent oversight with the support 
of management and assurance from the 
external auditors.

AUDIT COMMITTEE REPORT CONTINUED

AUDIT  
COMMITTEE
The Committee is chaired by Janice Stipp 
and comprises five Independent Non-
Executive Directors. The Committee acts 
independently of the Executive Directors 
and management. Our members have a 
range of skills and the Committee as a 
whole has experience relevant to the 
Sectors in which the Group operates. 
Janice has recent and relevant financial 
experience, as required by the Code.
The Group General Counsel & Company 
Secretary acts as Secretary to the 
Committee. The Executive Directors and 
Board Chair also regularly attend Committee 
meetings and subject matter experts are 
invited to present on specific topics as 
and when required. The Committee met with 
the external auditor during the year, without 
the Executive Directors or management 
being present.
The Audit Committee confirms that the 
Company has complied with the provisions 
of the Competition & Markets Authority 
Order throughout its financial year ended  
30 September 2024 and up to the date  
of this report.
Accounting for acquisitions and disposals
The Committee reviewed the accounting 
for acquisitions completed during the year, 
in particular the acquisitions of Peerless 
Aerospace and PAR Group. The acquisitions 
were material for the FY24 audit and, 
in accordance with IFRS 3 (Business 
Combinations), management has 
performed a full fair value exercise for 
these two acquisitions in this year’s financial 
statements. As part of their audit of the 
Group, the external auditor has performed 
work on: 
a)	 the Purchase Price Allocation (PPA);
b)	the opening balance sheet as at the 
acquisition date; and 
c) 	audit of any material fair value 
adjustments arising on the acquisition 
balance sheet. 
The Committee reviewed and challenged 
management’s assessment, which also 
included consideration of the external audit 
findings. The Committee concluded that 
the provisional accounting for these two 
acquisitions and the other five smaller 
acquisitions is appropriate. 
Provisions for excess and  
slow-moving inventory
The Committee reviewed the CFO report 
that set out the gross balances, together 
with any related provision against the 
carrying value of inventory. 
Financial reporting and significant 
financial judgements and estimates
The Committee considered and assessed:
•	 the Full Year and Half Year Results, and 
trading updates for recommendation 
to the Board;
•	 the appropriateness of accounting 
policies and practices, as well as critical 
accounting estimates and key 
judgements; and
•	 whether the Annual Report and Accounts, 
taken as a whole, is fair, balanced and 
understandable and provides the 
information necessary for shareholders to 
assess the Group’s position, performance, 
business model and strategy.
The Committee considered the matters set 
out below as being significant in the context 
of the consolidated financial statements for 
the year ended 30 September 2024. These 
were discussed and reviewed with 
management and the external auditor. The 
Committee then challenged judgements 
and sought clarification where necessary.
The Committee considered the judgements 
made in preparing the financial statements, 
including the accounting for acquisitions 
and associated valuation of intangible 
assets, the provisions for excess and 
slow-moving inventory, the potential 
for impairment of goodwill and the 
appropriateness of the Going Concern 
assumption. The Committee also reviewed 
the movements in the Group’s defined 
benefit pension schemes.
The Committee reviewed the bases used 
to value inventory held across the Group; 
it also considered the appropriateness of 
provisions held against the carrying value 
of inventory, having regard to the age and 
volumes of inventory relative to expected 
usage and considering the actions taken in 
response to commercial and trading-related 
matters during the year.
Following its review, which also included 
consideration of the external audit findings, 
the Committee concluded that the provision 
for excess and slow-moving inventory 
is appropriate.
Impairment of goodwill
The Committee considered the carrying 
value of goodwill and the assumptions 
underlying the impairment review. The 
judgements in relation to goodwill 
impairment largely relate to the assumptions 
underlying the calculations of the value in 
use of the cash-generating units (CGUs) 
being tested for impairment. 
These judgements are primarily the 
calculation of the discount rates, which have 
decreased, largely due to the reduction 
of the risk free rate and cost of debt; the 
achievability of management’s forecasts 
in the short to medium-term against the 
backdrop of a challenging macroeconomic 
environment; and the selection of the 
long-term growth rate. Following the review, 
which also included consideration of the 
external audit findings, the Committee 
concluded that the carrying value of the 
goodwill recorded is appropriate.

AUDIT COMMITTEE REPORT CONTINUED

ENGAGEMENT OF THE 
EXTERNAL AUDITOR
Other audit matters
The Committee also considered other 
matters including the valuation of the 
Group’s defined benefit scheme and the 
impact of the key actuarial assumptions 
on the balances. The Committee is aware of 
the UK High Court legal ruling in June 2023 
between Virgin Media Limited and NTL 
Pension Trustees II Limited that was 
subsequently upheld by the Court of Appeal 
on 25 July 2024 in which certain historic rule 
amendments were invalid if they were not 
accompanied by actuarial certifications. The 
Committee understands that this judgment 
will need to be reviewed for its relevance 
to the Diploma Holdings PLC UK Pension 
Scheme and due to the recency of this, 
the Pension Scheme advisers have not yet 
completed any analysis and no adjustments 
have been made to the consolidated 
financial statements as at 30 September 
2024. The Committee is satisfied with the 
year end position and the assumptions used.
In addition to the above, the Committee 
also seeks comments from the auditor on 
whether the Group’s businesses follow 
appropriate policies to recognise material 
streams of revenue, and their audit work 
carried out more generally has assessed 
whether there is any evidence of 
management override of key internal 
controls designed to guard against 
fraud or material misstatement. 
As part of its monitoring of the integrity 
of the financial statements, the Committee 
reviews whether suitable accounting 
policies have been adopted and whether 
management has made appropriate 
estimates and judgements, and seeks 
support from the external auditor to 
assess them.
Going Concern and Viability
The Going Concern and Viability assessment 
was prepared by management. In preparing 
the assessment, management carried out 
reverse stress testing as well as scenario 
analysis. Two scenarios were considered 
– the base case and the severe but plausible 
downside case. The base case reflects 
actual recent trading and the downside case 
reflects a more significant decline in trading, 
lower than forecast operating margins, and 
adverse cash flows, and is considered by 
management to be a severe but  
plausible downside scenario. 
The external auditor, led by audit partner 
Richard Porter, is engaged to express an 
opinion on the financial statements of 
the Group. The audit includes the 
consideration of the systems of internal 
financial control and the data contained 
in the financial statements, to the extent 
necessary for expressing an audit  
opinion on the truth and fairness of  
the financial statements.
During the year, the Committee carried out 
an assessment of the audit process, led by 
the Chair of the Committee and assisted 
by the Group CFO. The assessment 
focused on certain criteria that the 
Committee considered to be important 
factors in demonstrating an effective  
audit process. 
These factors included the quality of 
the audit process and the robustness of 
challenge to management; key audit risks 
and how these have been addressed; the 
planning and execution of the audit;  
and the role of management in the  
audit process. 
The Committee was satisfied that the PwC 
audit of the Company and Group had 
provided a robust and effective audit and 
an appropriate independent challenge 
of the Group’s senior management. 
It also supported the work of the 
Committee through clear and objective 
communication on developments in 
financial reporting and governance.

AUDIT COMMITTEE REPORT CONTINUED

The Group has ample liquidity and covenant 
headroom in each scenario for both Going 
Concern and Viability Statement purposes. 
The Audit Committee reviewed the 
assumptions underpinning each scenario 
and is satisfied with management’s 
assessment and conclusions on Going 
Concern and Viability. Further detail on 
the assessment of Viability and the 
Viability Statement are set out on page 72.  
Further details on Going Concern can  
be found on page 168.
Non-audit services
The Committee has approved the Group’s 
internal guidelines covering the type of 
non-audit work that can be carried out by 
the external auditor of the Group, in light 
of the regulation set out in the EU Audit 
Directive and Audit Regulation 2014 (the 
Regulations) and the FRC Revised Ethical 
Standard 2019.
The Group CFO does not have delegated 
authority to engage the external auditor  
to carry out any non-audit work, but must 
seek approval from the Chair of the  
Audit Committee.
Taxation services are not provided by the 
Group’s current audit firm. A range of firms 
are used for the provision of tax advice and 
any assistance with tax compliance matters 
generally. In addition, due diligence 
exercises on acquisitions and similar 
transactions are not provided by the auditor, 
but are placed with other firms.
All financial data is taken directly from each 
business’ trial balance, which is held in their 
local ERP system. This is reanalysed and 
formatted in a separate Group management 
reporting system, operated by the Group 
Finance department. There is no rekeying 
of financial data by the Group businesses 
to report monthly financial results. 
The Group’s internal audit function regularly 
audits the base data at each business to 
ensure it is properly reported through to 
the Group management reporting system.
Senior management of each business 
is required to confirm its adherence with 
Group accounting policies, processes and 
systems of internal control by means of 
a representation letter.
In conjunction with the upcoming 
requirements of the UK Corporate 
Governance Code 2024, the risk 
management and internal control framework 
was revitalised. This framework will provide 
a structured approach to ensure that 
significant financial and reporting, 
operational and cybersecurity, compliance 
and strategic risks are sufficiently mitigated 
by clearly defined key controls. The 
Committee is confident of management's 
plan to implement this framework, which will 
also enable the Board to execute its duty in 
compliance with the requirements of the 
new UK Corporate Governance Code 2024.
The Committee is responsible for reviewing 
the effectiveness of the Group’s system 
of internal control. The system of internal 
control is designed to manage, rather than 
eliminate, the risk of failure to achieve 
business objectives and can only provide 
reasonable and not absolute assurance 
against material misstatement or loss. 
The Group has the necessary procedures 
in place to ensure that there is an ongoing 
process for identifying, evaluating and 
managing the principal risks to the Group. 
These procedures are in line with the FRC’s 
guidance. The Board has established a clear 
organisational structure with defined 
authority levels. 
The day-to-day running of the Group’s 
business is delegated to the Executive 
Directors of the Group, who are supported 
by the heads of each business Sector and 
functional heads of the Group.
Key financial and operational measures 
relating to revenue, cash and receivables 
are reported on a weekly basis. 
Detailed management accounts and 
key performance indicators are prepared 
monthly using a robust proprietary reporting 
system to collect and analyse financial data 
in a consistent format. Monthly results are 
measured against both budget and 
subsequent reforecasts, which have been 
approved and reviewed by the Board. All 
capital expenditure exceeding predefined 
amounts must be supported by a paper 
prepared by management.
The external auditor is retained to carry out 
assurance services to the Committee in 
connection with an Interim Review of the 
Group’s half year consolidated financial 
statements (£80,900). Included within this 
is access to PwC's Viewpoint technical 
subscription service.
With the exception of these services, PwC 
has not provided any non-audit services 
to the Group or its subsidiaries and has 
confirmed its independence to the Audit 
Committee. Further information is set  
out in note 27 to the consolidated  
financial statements.
The Committee assures itself of the 
auditor’s independence by receiving 
regular reports from the external auditor 
that provide details of any assignments 
and related fees carried out by the auditor in 
addition to its normal audit work, and these 
are reviewed against the above guidelines. 
PwC has reconfirmed its independence for 
the current financial year.
Risk management and internal control
The principal risks and uncertainties that 
are currently judged to have the most 
significant impact on the Group’s long-
term performance are set out in a separate 
section of the Strategic Report on risk 
management and internal control on 
pages 54 to 60.

AUDIT COMMITTEE REPORT CONTINUED

The Committee has reviewed the 
effectiveness of the Group’s risk 
management and internal control systems 
for the period from 1 October 2023 to the 
date of this report. Taking into account the 
matters set out on pages 57 to 60 relating 
to principal risks and uncertainties and the 
reports from the Group Head of Internal 
Audit, the Board, with the advice of the 
Committee, is satisfied that the Group has 
in place effective risk management and 
internal control systems.
Internal audit
The Group maintains an internal audit 
department, which reports directly to 
both the Group CFO and Chair of the Audit 
Committee. The department comprises a 
Group Head of Internal Audit and three 
Group Internal Auditors.
The Committee received, considered and 
approved the 2024 Internal Audit plan which 
was developed using a risk-based approach 
considering the Group's control environment 
and principal risks. The audit plan was 
developed based on the premise that all 
businesses are audited at least once every 
three years. In 2024, the Group Head of 
Internal Audit also commissioned a 
speciality Operational Technology review 
conducted by an external specialist. 
The scope of work carried out by internal 
audit generally focuses on the internal 
financial, operational and compliance 
controls operating within each business, 
including risk management activities and 
business process improvements. Formal 
written reports are prepared on the results 
of each internal audit visit that set out 
internal control weaknesses/risks identified 
during their work, together with 
recommendations to improve the internal 
control environment and mitigate these 
weaknesses/risks. These reports are timely 
and regularly discussed with senior 
management. The reports are also shared 
with the external auditors.
During the year, a new web-based audit 
system was implemented which allows 
documentation of audit testing, reporting 
and recording and live tracking of audit 
issues. The Group Head of Internal Audit 
monitors progress on the resolution of 
issues and regularly engages with Sector 
management to ensure engagement on 
resolution is maintained at all levels. 
The Group Head of Internal Audit formally 
reports to the Committee on the results of 
the work carried out by the Internal Audit 
department during the year. The Committee 
reviews management’s responses to 
matters raised, including the time taken to 
resolve such matters. Updated reports on 
progress against the plan are provided at 
regular intervals and the Audit Chair also 
meets separately with the Group Head  
of Internal Audit to review some of the 
department’s reports and discuss  
their findings.
There were no significant or material matters 
identified in the internal audits undertaken 
during the current financial year. Several 
recommendations were again made this 
year to the businesses on implementing 
adequate and effective internal controls 
and procedures aimed at improving existing 
processes around cybersecurity, inventory 
management and procurement practices.
At the end of the year, the CFO conducted 
an internal review of the effectiveness of the 
Internal Audit function. The feedback was 
positive overall with the function considered 
to have operated effectively.
The Committee also conducted the annual 
review of the effectiveness of the internal 
audit department, including its audit plan, 
general performance and relationship with 
the external auditors. Based on its review, 
the Committee was satisfied with the 
effectiveness of the Group’s internal audit 
function, specifically that the internal audit 
department is sufficiently independent of 
Executive Management and has sufficient 
resources and scope that is appropriate to 
the size and nature of the Group.
Whistleblowing
The Committee also monitors the adequacy 
of the Group’s Whistleblowing Policy and 
protocols, which provide the framework to 
encourage and give employees confidence 
to speak up and report irregularities. The 
Policy, together with hotline posters, which 
are available to all businesses. Employees 
are encouraged to raise concerns via the 
confidential multilingual hotline, which is 
managed by an independent external 
company and is available 24/7, 365  
days a year.
All reports are provided to the Group 
Company Secretary & General Counsel for 
review to ensure that they are appropriately 
investigated – with the support of internal 
audit and external resource, if required. 
Most matters reported through the 
whistleblowing service relate to personnel 
and HR matters and, while these are not 
areas for review by the Committee, such 
matters are duly investigated in the same 
manner as any other issue raised.

NOMINATION COMMITTEE REPORT

Dear Shareholder 
I am pleased to set out the report 
on the activities of the Nomination 
Committee during the year. 
The Board is of the view that it is essential 
to have an appropriate mix of experience, 
expertise, diversity and independence. 
Such attributes enable the Board as a whole 
to provide informed opinions and advice 
on strategy and relevant topics, thereby 
discharging its duty of oversight. 
Appointments to the Board are made with 
consideration of the experience and 
expertise of existing Directors, any required 
skill sets or competencies, and the strategic 
requirements of the Group. During FY24 and 
into FY25, the composition of the Board has 
continued to change reflecting the 
continued evolution of the Board, the 
Company and the Group.
A fundamental responsibility of the 
Committee is to ensure plans are in place for 
orderly succession to the Board, as well as 
our Group Company Secretary and senior 
management positions, and the Committee 
debates these regularly. 
The key focus of the Committee during this 
past year has been on Board succession 
planning and composition, primarily the 
search for the Senior Independent Director 
and an additional director to bring additional 
skills and experience to the Board following 
the departures of directors. 
Ensuring the right 
mix of skills and 
experience to 
deliver long-term 
value for our 
stakeholders.
Demand for talent amongst UK listed 
companies in this regard is high and it is 
therefore acknowledged that the search for 
suitable candidates to join the Board, having 
regard to the individual’s skills, experience 
and knowledge and requirements of the 
Board, took longer than envisaged when I 
wrote to you last year. We are confident that, 
following the recent refresh of the Board's 
composition, the Board is well-positioned 
for the future.
The Board will maintain oversight of the 
range of activities the Group is pursuing 
aimed at increasing the diversity of our 
workforce – including the executive pipeline 
that is essential for Executive Director 
succession planning. We have written 
elsewhere (see page 51) about our Group-
wide approach to diversity and inclusion, 
which emanates from the Board  
and impacts the approach of the 
Nomination Committee. 
The guidance from the Financial Reporting 
Council (FRC) on board effectiveness 
recognises a breadth of diversity that goes 
beyond just gender and race, and includes 
personal attributes including intellect, 
critical assessment, judgement, courage, 
honesty and tact; and the ability to listen 
and forge relationships and develop trust. 
This ensures that a board is not comprised 
of like-minded individuals. 
The Committee agrees that diversity is vital 
when reviewing the composition of the 
Board and setting the criteria for the 
recruitment of new appointees, alongside 
succession planning activities. External 
search consultants are expected to make 
every effort to put forward a diverse range 
of candidates for new Board positions. 
Whilst appointments will continue to be 
made on merit and against objective criteria, 
it remains the Committee’s intention that the 
diversity of the Board will continue to 
increase over time.
The Committee has also maintained its 
focus on the executive succession pipeline 
and senior management succession plans 
within the Group, reflecting its responsibility 
to ensure appropriate plans are in place. 
David Lowden
Nomination Committee  
19 November 2024
The Committee continually monitors the 
balance on the Board to ensure we have the 
right combination of skills, experience and 
knowledge consistent with the long-term 
strategy of the Group. This allows us to 
identify where further focus is needed in 
the coming years and beyond. 
We are mindful of the importance of 
improving diversity and inclusion, together 
with the targets set by the Hampton-
Alexander Review and the Parker Review. 
The Board sees increasing diversity at the 
Board level as an essential element in 
attaining our strategic objectives and 
achieving sustainable and balanced 
development for the Group. At the end of 
the financial year, four out of eight Directors 
(50%) were women but we had no Board 
members from an ethnic minority 
background, and therefore did not meet 
the target ethnic minority representation.

Succession planning
The Committee formally reviews succession 
planning for the Board, Group General 
Counsel & Company Secretary, and senior 
management at least once each year, 
taking into account the challenges and 
opportunities facing the Group and the 
background, skills and expertise that will be 
required by the Group in the future. During 
2024, the Committee undertook a regular, 
thorough analysis of the Board’s 
competencies. The Committee also 
considered how the Board would need to 
evolve to be fit for the future, as well as any 
potential gaps that may need to be filled 
through succession or training. 
The Group CEO manages the development 
of succession plans for the Executive Team, 
and these are overseen by the Committee. 
The Group CEO and Group HR Director 
presented a succession planning and  
talent management update to the Board  
in January 2024. 
The Committee is aware of the importance 
of identifying critical roles within the 
businesses to ensure Diploma retains and 
motivates key talent and has the necessary 
skills for the future. Overall, it was clear that 
we have a good executive and management 
succession planning process and, 
importantly, succession is being actively 
managed by the Executive Team to achieve 
the desired long-term outcomes.
The standard term for Non-Executive 
Directors is three years. They normally serve 
for a maximum of nine years, which is split 
across three terms of three years each. All 
Directors are subject to annual re-election. 
With only specific exceptions that may 
be necessary to ensure Board continuity, 
Non-Executive Directors shall not stand for 
re-election after they have served for the 
period of their independence of nine years, 
as determined by applicable UK standards.

PROCESS FOR BOARD APPOINTMENTS 
Induction and professional development
The Chair, assisted by the Group Company 
Secretary, is responsible for ensuring that 
there is a properly constructed and timely 
induction for new Directors when joining the 
Board. Upon appointment, all new Directors 
are provided with a comprehensive 
induction, where they meet with key 
members of management and familiarise 
themselves with all core aspects of the 
Group, its businesses and the markets in 
which it operates. 
Directors are encouraged, wherever 
possible, to visit the Group’s sites so that 
they can get a better understanding of the 
business and interact with employees. Site 
visits by individual Directors (and the Board 
as a whole) are undertaken during the year 
as well, with this year focusing primarily 
International Seals. 
These visits allow Directors to see Diploma’s 
safety and sustainability processes, to talk 
with local management and workforces and 
to assess how effectively Diploma’s culture 
is communicated and embedded at all levels. 
The Chair also has the responsibility of 
ensuring that Directors receive training on a 
continual basis in support of their ongoing 
development. This training is provided by 
way of technical updates, reports and 
briefings prepared for Board meetings. 
Directors have full access to our corporate 
advisors as well as a regular and 
comprehensive supply of financial, 
operational, strategic and regulatory 
information to help them discharge  
their responsibilities.
ONBOARDING PROCESSES
The decentralised nature of the Group 
has always made induction processes 
complex. Ideally we seek to arrange 
face-to-face meetings with key executives 
and functional leadership, introductions to 
their direct reports, one-to-ones following 
the initial meetings, and site visits arranged 
to key businesses. Parts of the induction 
plan are conducted via video calls, 
particularly where key people are located 
outside of country of residence of the 
particular Director. This permits directors to 
have considerably greater exposure to the 
various businesses and personnel and we 
are pleased that we can once again 
encourage directors to visit our businesses 
and appreciate our culture and colleagues 
in person, as well as continuing to develop 
their understanding of each business.
When making Board appointments, we 
follow the five steps outlined below. We 
disclose the name of the search agent 
and any other connection they have with 
Diploma in our Annual Report and 
Accounts published following the search. 
In due course, a tailored induction 
programme is developed for the  
new Director. 
During the year we engaged Korn Ferry in 
connection with the recruitment of Janice 
Stipp and Katie Bickerstaffe. Russell 
Reynolds Associates were engaged in 
connection with the appointment of Ian 
El-Mokadem. Neither Korn Ferry or 
Russell Reynolds Associates have any 
other connection to the Group, other 
than providing executive  
search services.

Diversity & Inclusion
Diversity is a key consideration when 
assessing the Board’s composition and 
that of its Committees, as well as the wider 
Group, to ensure the development of a 
diverse pipeline for succession. The 
Committee has worked hard to ensure the 
Board is sufficiently diverse to meet and 
support its future strategic developments. 
The Board and this Committee consider a 
broad definition of diversity when setting 
policies and appointing Directors. This 
includes: ethnicity, religion, socio-economic 
background, gender, sexual orientation, 
age, disability, partnership status, culture, 
personality and professional experience. 
The Board confirms that as at 30 September 
2024 (being the reference date selected 
by the Board for the purposes of this 
disclosure) the Company had fully complied 
with the gender diversity targets of Listing 
Rule 6.6.6.R(9) and the FTSE Women  
Leaders Review. 
The Committee notes the Parker Review and 
the ethnicity diversity targets of Listing Rule 
6.6.6R(9) and acknowledged that further 
work is required for the Board and its 
Committees to become more ethnically 
diverse. In order to develop a truly diverse 
culture, the Board and its Committees 
recognises it needs to set the tone 
and become more proportionately 
representative of its workforce and 
the stakeholders it serves.
As at 30 September 2024 the Company did 
not meet the Listing Rule 6.6.6R(9) ethnicity 
target for Board members of at least one 
individual on its Board from a minority ethnic 
background. However, following the 
appointment of Ian El-Mokadem in 2025, 
the Company will satisfy this requirement. 
In order to collect the data for the gender 
and ethnic diversity disclosures, the Board 
and its executive management team were 
each sent a series of questions to complete, 
including asking how they self-identify in 
each of the designated categories under 
the Listing Rules disclosure. This data was 
then collected with results recorded and 
retained for future records.

Board evaluation
The Board conducts an annual evaluation of 
its performance and that of its committees 
and, in accordance with good practice, 
engages an independent third-party 
facilitator to assist in this process every 
three years. For the year ended 30 
September 2024, the evaluation of the 
Board as a whole and of its committees 
was externally facilitated by BoardClic. 
This was the Board's first collaboration 
with BoardClic, a leading provider of board 
evaluation services. BoardClic's approach 
is aligned with international best practice 
for board reviews, including the Corporate 
Governance Institute's Code of Practice, 
ensuring a robust and effective review 
process. Board members completed 
questionnaires regarding the operation 
and effectiveness of the Board and its 
Committees. 
The below recommendations were made 
following last year's Board performance 
evaluation.
Findings were collated by BoardClic to form 
the basis of interviews with each director, 
the Company Secretary and key executives 
who regularly interacted with the Board. 
The results of the 2024 evaluation process 
were considered and debated in detail by 
the Board. The conclusion was that the 
Board, its members and its committees 
continue to function well, but there was 
scope for improvement reflecting the 
increased size as well as the increasing 
complexity incumbent upon the Group. 
Directors operated in an atmosphere of 
open and constructive debate with a 
good breadth of skills, experience, and 
viewpoints. Following the evaluation, a 
number of recommendations were made 
which are outlined in the table opposite.
Recommendation
Progress made
Board and Committee 
structures
Committee structures and schedules were deemed appropriate

Improved understanding of key stakeholders, including 
customers, during Board business visits and with additional 
deep-dive sessions as appropriate. 
KEY AREAS FOR DEVELOPMENT
The below recommendations were made following this year's externally facilitated 
Board performance evaluation. The Company expects to update shareholders on the 
progress made in relation to the matters identified below in its 2025 Annual Report 
and Accounts.

REMUNERATION COMMITTEE REPORT

Dear Shareholder 
I was delighted to join the Diploma 
Board in June 2023 and accept the 
role of Chair of the Remuneration 
Committee with effect from  
July 2024. My heartfelt thanks  
to my predecessor, Andy Smith  
for his support in ensuring a 
seamless transition. 
As the Chair of the Remuneration 
Committee, I am pleased to present 
our Directors’ Remuneration Report (DRR) 
for the year ended 30 September 2024.
Performance, business growth 
and context
It is a pleasure to present my first DRR as 
Remuneration Committee Chair with such 
positive outcomes to report. Diploma has 
delivered exceptional performance under 
the Executive Directors’ leadership. Since 
the appointment of Johnny Thomson as 
CEO, the Group has grown total revenue 
by 150% to £1,363m, with a strong average 
annual organic growth of 7%. It has 
accelerated adjusted earnings per 
share (EPS) by 127% to 145.8p, and 
effectively deployed £1.3bn of capital 
on 41 complementary acquisitions, at 
an average return on capital of 17%. This 
consistently strong performance has been 
achieved because of a focused growth and 
scaling strategy, with exceptional execution. 
Diploma has grown in both scale and 
complexity in this period. We have 
further penetrated our core geographies; 
successfully diversified our portfolio to build 
revenue resilience through end markets and 
product expansion; and have grown the size 
of our workforce by 75%. 
Ensuring that we are nurturing our growing 
workforce is an issue close to my heart and 
a responsibility of the Committee that I do 
not take lightly. Since joining the Board it has 
been encouraging to observe a clear focus 
on employee engagement and culture as 
part of our Delivering Value Responsibly 
(DVR) strategy. 
The Group’s strong performance has driven 
total shareholder returns (TSR) of 278% in 
the period since Johnny Thomson became 
CEO (February 2019), compared to a FTSE 
100 average of 46%. Over the same period, 
market capitalisation has grown to £5.9bn, 
from £1.5bn, with Diploma’s position in the 
FTSE rising from 197 to 61 over the same  
time period. 
The Board recognises the pivotal role of 
exceptional leadership in delivering this 
strong performance at increased scale and 
complexity, within a decentralised Group. 
Our Group reward philosophy is to drive and 
reward high performance and we’re focused 
on ensuring that the Executive Director 
Remuneration Policy and pay frameworks 
across the organisation are aligned to this.
Performance and pay outcomes for 2024 
In the past year, Diploma has delivered 
another strong performance and the 
organisation is well positioned to deliver 
sustainable quality compounding into  
the future. 
Bonus outcomes for FY24
The FY24 bonus was based on 50% 
adjusted operating profit, 25% revenue 
and 25% free cash flow, with operating 
profit and revenue agreed by the 
Committee to be assessed on a constant 
currency basis, consistent with previous 
years. On a constant currency basis, 
the Group’s adjusted operating profit in 
2024 was £293m exceeding the maximum 
target of £279m and revenue was £1,398m, 
exceeding the maximum target of £1,372m. 
Reported free cash flow was £198m, 
exceeding the maximum target of £176m. 
Against this backdrop of exceptional 
business performance in FY24, I am pleased 
to report that the formulaic outturn of the 
bonus plan for the year is 100% of maximum 
opportunity, having exceeded the stretching 
maximum target level for all bonus 
performance measures.
This results in full bonus payments for 
Johnny Thomson and Chris Davies, 
respectively, representing 125% of salary 
for both. For Chris, 50% of his bonus will 
be deferred into shares until he meets his 
minimum shareholding requirement (250%) 
in line with the Policy; Johnny’s shareholding 
far exceeds the minimum shareholding 
requirement so his bonus is not required to 
be deferred by the Policy and will be paid 
entirely in cash. 
2021 PSP Award Vesting 
The 2021 Performance Share Plan (PSP) 
award came to the end of its three-year 
performance period on 30 September 
2024. This award was calculated with 50% 
based on growth in adjusted EPS and 50% 
on TSR outcomes. Return on adjusted 
trading capital employed (ROATCE) 
performance underpins the plan. 
Diploma’s three-year CAGR for adjusted 
EPS performance was 19.6%, exceeding 
the maximum target of 12% CAGR and our 
three-year TSR growth performance was 
50.9%, compared to the upper quartile of 
the FTSE 250 (excluding investment trusts) 
peer group of 26.3%, placing Diploma at 
the 87th percentile when compared to the 
comparator group. Finally, our ROATCE 
was 19.1%, which is in line with the Group’s 
financial model and Board’s expectation. 
As a result of this superior performance over 
the period, the PSP has vested at maximum 
for all PSP participants including the 
Executive Directors. 
The Committee considered both the FY24 
bonus and 2021 PSP outturns within the 
wider business and economic context,  
and agreed unanimously that they are  
a fair reflection of the business’s 
performance and fair reward for  
participants of these plans. Therefore no 
Committee discretion will be exercised to 
alter the formulaic outcomes.

REMUNERATION COMMITTEE REPORT CONTINUED

Remuneration policy review 
This year the Committee conducted a 
comprehensive review of the existing 
Policy to ensure that it remains fit for 
purpose. It is imperative the Company 
can retain and attract the talent that has 
delivered the shareholder value creation 
to date and in the future. The Remuneration 
Committee and the Board believe it remains 
critical that remuneration keeps pace with 
the growth and scaling of the Group. 
Against this backdrop of exceptional 
growth, the Board decided to expedite 
this Remuneration Policy review by one year. 
Over the summer, we conducted 
extensive consultation with our shareholders 
representing 53% of our register as well as 
all three proxy agencies. Feedback from 
these sessions was very helpful to the 
Committee in shaping the final proposals 
outlined below. We were pleased to hear 
from our shareholders that they were 
supportive of the changes outlined and 
understood the rationale and requirements 
of the Company in ensuring remuneration 
remains aligned to the market and retentive 
to our high-performing executives as the 
business continues to grow and deliver 
market-leading shareholder returns.
We are proposing to update the Policy for 
our Executive Directors to reflect that: 
•	 The Group has delivered exceptional 
performance over the last five years, with 
ca. 127% adjusted EPS growth, taking the 
Group from FTSE 197 to FTSE 61 with a 
strong trajectory to continue this track 
record
•	 Competitive and attractive remuneration 
is key to retaining a high-performing CEO 
and CFO who have been instrumental in 
delivering performance to date
•	 The Group’s strategy remains ambitious to 
deliver sustainable quality compounding 
for the long term
•	 In addition to moving up the FTSE, the 
Group has grown in scale and complexity 
and requires exceptional leadership to 
continue to execute its growth strategy
The proposed Policy and implementation 
changes would:
•	 Increase bonus policy maximum and base 
salaries to keep pace with growth and 
market
•	 Introduce a non-financial metric to the 
bonus to ensure a critical focus on 
colleague engagement as we grow  
and scale
•	 Ensure continued Committee review 
of performance targets to ensure they 
remain appropriately stretching as the 
business continues to grow and scale
Specifically on bonus we are proposing to 
increase the opportunity under the bonus 
plan for Executive Directors which, at 125% 
of salary, currently sits below the lower 
quartile of the FTSE 51-100. The Committee 
is proposing increasing this value to a 
maximum of 200% for CEO, and to 180% 
for CFO, implemented immediately – 
aligning both roles with the median of the 
FTSE 51-100 peer set (with Diploma 
currently positioned at FTSE 61). 
We will also introduce a single non-financial 
measure in our bonus to reflect a key aspect 
of our DVR strategy. The measure, weighted 
at 5%, will be employee engagement to 
recognise the importance of a highly 
motivated workforce within a decentralised 
and fast-growing service business. The 
maturity of our Diploma employee survey 
will enable reliable, rigorous reporting. 
To ensure base salaries keep pace with the 
growth of the Group, are competitive and 
recognise the additional complexity within 
leadership roles, the Board has also 
awarded a CEO salary increase of 12% 
reflecting Johnny’s position in relation to 
the relevant FTSE 51-100 market benchmark 
and his continued performance in role. The 
CFO will receive a salary increase of 4%, in 
line with the increase rate provided to the 
wider Diploma workforce. 
The sum of these changes would place our 
CEO’s total compensation just below 
median of the FTSE 100 on a target basis – 
in line with Diploma’s positioning at FTSE 61. 
Executive remuneration for 2025 – 
implementation 
Subject to shareholder approval of the 
proposed policy, the following remuneration 
will be implemented in 2025 for  
Executive Directors.
Fixed pay
In line with the proposed salary increases as 
explained above, Johnny Thomson’s 2025 
base salary will be £918,400 and Chris 
Davies’ will be £530,400 per annum. There 
will be no change to the cash allowance in 
lieu of pension contribution for Executive 
Directors, which remains at 4% of base 
salary, aligned to the wider workforce 
average contribution level.

REMUNERATION COMMITTEE REPORT CONTINUED

Annual Bonus 
The 2025 annual bonus will see the 
implementation of a new performance 
measure focused on the DVR strategy. 
Namely, the 2025 bonus will comprise 
50% adjusted operating profit, 20% 
revenue, 25% free cash flow and 5% 
employee engagement. Targets will be 
based on the Board approved budget and 
the Committee will ensure there is sufficient 
rigour and stretch in target setting to 
support the high-performance track record 
and culture. The maximum opportunity will 
be 200% of base salary for Johnny Thomson 
and 180% of base salary for Chris Davies, 
in line with the new policy proposals.
PSP 
The 2024 PSP award will operate 
consistently with the previous year. 
Performance measures remain unchanged 
for the 2024 PSP grant; 75% of the total 
award will be based on adjusted EPS growth 
and 25% will be based on TSR relative to the 
FTSE 100 (excluding investment trusts), with 
an underpin on ROATCE. The award levels 
will also remain the same, these are 300% 
of base salary for Johnny Thomson and 
250% of base salary for Chris Davies.
A focus on wider workforce pay 
and conditions
The success of Diploma and its superior 
value creation is founded upon our unique 
culture, and our colleagues are core to this. 
The Committee is assured that we have an 
engaged and healthy workforce, and that 
colleagues are fairly and well-rewarded. 
Retaining top talent in the highly competitive 
and increasingly global talent market within 
which we operate is critical. 
We are pleased to report that our employee 
engagement continues to be high at 79%. 
However, we know that this can be a 
challenge as a decentralised business 
and are conscious of maintaining an acute 
focus on this as we continue to scale, hence 
including this as a performance metric in 
this coming year’s executive bonus plan.
Given our decentralised model, we take 
the approach of empowering our business 
leaders to make remuneration decisions 
locally to appropriately account for different 
market conditions. As a Committee, we are 
sure to maintain oversight so we can make 
executive remuneration decisions that are 
cognisant of the wider workforce’s pay  
and conditions. 
Some key ways that we have sought to 
further support, incentivise and reward 
our colleagues during the year:
•	 We became an accredited Real Living 
Wage employer across our UK businesses 
(with the exception of R&G, where we are 
currently working towards accreditation) 
•	 We have increased remuneration through 
base salary and annual bonus for senior 
management to align with the Group’s 
increased scale and complexity
•	 We have built an ambitious capability 
agenda, with focus on roles with increased 
complexity, to upgrade capability and 
intensify personal development. This is 
complemented by competitive and 
motivating reward. 
Non-executive directors
Non-Executive Director fees were reviewed 
in the year in the context of increased 
responsibilities, time and skill requirements, 
as well as market data, now that Diploma is 
firmly established as a FTSE 100 business. 
Non-Executive Director fees continue to lag 
our new size and scale in market comparison 
and increases are proposed to address this. 
The increases are laid out on page 115. The 
Committee agreed these increases were 
important to recognise the increase in 
expectation of the Board and to ensure we 
can retain and appoint directors with the 
requisite skills to provide critical governance 
and oversight of the business in the face of 
an increasingly complex landscape, driven 
by supply chain, labour, geopolitical and 
technological disruptions.
Conclusion
In closing, I would like to thank shareholders 
for their meaningful engagement and 
support over the year as we consulted on 
the new Remuneration Policy proposals. 
I would also like to thank my fellow Board 
members for welcoming me onto the Board 
and helping me transition into the role of 
Remuneration Committee Chair. I am 
energised by the culture, high performance 
and growth trajectory of the business and 
confident in the Policy we have proposed to 
shareholders to support this. We very much 
look forward to receiving your support at 
the AGM on the 15 January 2025.

REMUNERATION AT A GLANCE CONTINUED

This section sets out the Directors’ 
Remuneration Policy proposed for approval 
by shareholders at the Company’s AGM on 
15 January 2025. The Company’s current 
Remuneration Policy was approved by 
shareholders at the AGM on 17 January 
2024 and the updated policy, subject 
to shareholder approval is intended to  
remain in effect for three years from  
the AGM in 2025. 
The Committee reserves the right to 
approve payments on terms that differ from 
the Policy where the terms of the payment 
were agreed before the Policy came into 
effect or were agreed at a time when the 
relevant individual was not a Director  
of the Company. 
The Committee may also make minor 
amendments to the arrangements for 
Directors described in the Policy without 
shareholder approval for regulatory, tax or 
administrative purposes or to take account 
of a change in legislation.

Setting the policy
The Remuneration Committee is responsible 
for setting the overall remuneration policy 
and is conscious to consider all stakeholders 
and perspectives in doing so. The 
Committee seeks independent advice 
and takes care to mitigate any conflicts of 
interest by ensuring that no Director makes 
decisions relating to their own remuneration 
and by working with the Audit Committee 
to ensure there is an appropriate balance 
between incentives to drive performance 
in line with strategic goals and risk 
management. The Committee considers 
market data and developments regularly  
to inform policy and its implementation  
each year. 
The sections below outline how 
performance measures are selected and 
how we have considered both shareholder 
views through meaningful shareholder 
consultation and the workforce perspective. 
Selection of performance measures 
and targets for Annual Bonus and PSP
The Annual Bonus Plan is designed to drive 
the annual financial and strategic objectives 
of the business. Performance measures 
selected are aligned to the Company’s 
strategic plan and key objectives. Targets are 
set by reference to internal budget. Details 
of the measures selected for FY25 and the 
rationale behind the selection can be found 
in the Annual Report on Remuneration. 
The PSP is designed to drive the delivery 
of the Company’s longer-term objectives 
and support the delivery of value for 
shareholders. Performance measures 
are selected to align with these objectives 
and targets are set by reference to internal 
long-term business plans. Any major 
adjustment in the calculation of 
performance measures will be disclosed 
to shareholders on vesting. Details of 
the measures selected for FY25 and the 
rationale behind the selection can be found 
in the Annual Report on Remuneration.

REMUNERATION POLICY CONTINUED

On-target remuneration assumes an Annual 
Performance Bonus Plan of 50% of the 
maximum for the Executive Directors. It has 
been assumed that a face value limit of 
300% of base salary (CFO: 250%) applies 
to each PSP award. On-target vesting of 
PSP awards assumes an adjusted EPS 
growth of 7.67% p.a. and TSR performance 
which is equivalent to 50% of the maximum 
vesting under the PSP. Maximum 
remuneration assumes maximum annual 
performance bonus and maximum vesting 
of PSP awards. No dividend equivalents are 
assumed. No share price growth is assumed 
other than in the Stretch bar.
Consideration of shareholder views
The Committee will consult with its major 
shareholders in advance of any significant 
changes to the approved Policy or exercise 
of discretion, as appropriate, to explain 
their approach and rationale fully and 
to understand shareholders’ views. 
Additionally, the Committee considers 
shareholder feedback received in relation 
to each AGM alongside any views expressed 
during the year. The Committee also reviews 
the executive remuneration framework in the 
context of published investor guidelines or 
appropriate regulation including the UK 
Corporate Governance Code. 
A thorough consultation was conducted for 
this policy review as explained on page 98. 
Employee Consultation
The Group seeks to promote positive 
relations with colleagues. The Committee 
is mindful of the pay increases, incentive 
outcomes and share award participation 
in relevant markets across the rest of the 
Group when considering the remuneration 
of the Executive Directors. 
The Board as a whole takes responsibility for 
gathering the views of Diploma’s workforce, 
and does so through multiple channels of 
engagement. While the Committee does 
not consult employees directly when setting 
the Executive Directors’ remuneration policy, 
the senior management team engages with 
employees, either on a business-wide basis 
in the context of smaller focus groups, 
to solicit feedback generally on a wide 
range of matters, including remuneration. 
Feedback is passed to the Committee 
via the Executive Team. 
Differences in remuneration policy 
for other employees
The Company reviews compensation 
arrangements including base salaries for the 
wider employee population annually. Similar 
to the Executive Directors, salary increases 
for the wider population are determined 
based on a number of factors, including 
individual and business performance, level 
of experience, scope of responsibility, 
external competitive benchmarking, and 
general salary increases across the Group. In 
line with the Group’s decentralised model, 
compensation is agreed locally, with 
governance and guidance provided 
by the Group. 
The Company also seeks to provide an 
appropriate range of competitive benefits 
(including pension) to employees in line with 
their local markets. Senior managers have 
incentive plans aligned with the Executive 
Directors and there is a framework on 
remuneration which ensures alignment at 
different levels. Bonus plans for the 
workforce are agreed locally with oversight 
from the Sector management teams. 
Service contracts
The Executive Directors’ service contracts, 
including arrangements for early termination, 
are carefully considered by the Committee 
and are designed to recruit, retain and 
motivate Directors of the calibre required 
to manage the Company and successfully 
deliver its strategic objectives. The 
Committee considers that a rolling 
contract with a notice period of one 
year is appropriate for existing and 
newly appointed Directors.
The Executive Directors’ service contracts, 
copies of which are held at the Company’s 
registered office, together with any service 
contract for new appointments, contain 
provisions for compensation in the event 
of early termination or change of control, 
equal to the value of salary, pension and 
contractual benefits for the Director’s notice 
period. The Company may make a payment 
in lieu of notice in the event of early 
termination and the Company may make 
any such payment in instalments with 
the Director being obliged in appropriate 
circumstances to mitigate loss (for 
example by gaining new employment). The 
Committee considers that these provisions 
assist with recruitment and retention and 
that their inclusion is therefore in the best 
interests of shareholders.

Executive Directors who served during 
the year are set out below:

REMUNERATION POLICY CONTINUED

Payment for loss of office
The Committee has considered the 
Company’s policy on remuneration for 
Executive Directors leaving the Company 
and is committed to applying a consistent 
approach to ensure that the Company  
pays no more than is fair and reasonable  
in the circumstances.
The loss of office payment policy is in line 
with market practice and will depend on 
whether the departing Executive Director 
is, or is deemed to be treated as, a ‘good 
leaver’ or a ‘bad leaver’. In the case of a 
‘good leaver’ the Policy includes:
•	 Notice period of 12 months’ base salary, 
pension and contractual benefits or 
payment in lieu of notice.
•	 Bonus payable for the period worked, 
subject to achievement of the relevant 
performance conditions. Different 
performance measures (to the other 
Executive Directors) may be set for a 
departing Director as appropriate, to 
reflect any change in responsibility.
•	 Vesting of award shares under the 
Company’s long-term incentive plan 
is not automatic and the Committee 
would retain discretion to allow partial 
vesting depending on the extent to 
which performance conditions had been 
met and the length of time the awards 
have been held. Time prorating may be 
disapplied if the Committee considers 
it appropriate, given the circumstances. 
Performance will normally be measured to 
the end of the normal performance period 
and, to the extent applicable, vest on the 
normal vesting date, save in exceptional 
circumstances when the Committee 
may determine that early vesting should  
still apply.
•	 The Committee will provide for the leaver 
to be reimbursed for a reasonable level of 
legal fees in connection with a settlement 
agreement and outplacement services, 
where appropriate.
When calculating termination payments, the 
Committee will take into account a variety of 
factors, including individual and Company 
performance, the obligation for the 
Executive Director in appropriate 
circumstances to mitigate loss (for example, 
by gaining new employment) and the 
Executive Director’s length of service.
The Committee reserves the right to 
make additional exit payments where 
such payments are made in good faith in 
discharge of an existing legal obligation 
(or by way of damages for breach of such 
an obligation) or by way of settlement or 
compromise of any claim arising in 
connection with the termination of 
a Director’s office or employment.
Change of control
Change of control provisions provide 
compensation equal to the value of salary, 
pension and contractual benefits for the 
notice period. In the event of a change in 
control, vesting of an award of shares under 
the Company’s PSP depends on the extent 
to which performance conditions had been 
met at that time. Time prorating may be 
disapplied if the Committee considers it 
appropriate, given the circumstances of 
the change of control.
Malus and clawback
Malus provisions apply to all awards made 
under the Company’s long-term incentive 
and annual bonus plans which give the 
Committee the right to cancel or reduce 
unvested share awards (or in the case of 
the Annual Performance Bonus Plan, 
cash payments) in the event of material 
misstatement of the Company’s financial 
results, significant reputational damage 
to the Company, miscalculation of a 
participant’s entitlement, individual 
gross misconduct or of corporate failure  
(resulting in a liquidation or the appointment 
of administrators).
The clawback arrangements permit the 
Committee to recover amounts paid 
to Executive Directors in specified 
circumstances and further safeguard 
shareholders’ interests.

REMUNERATION POLICY CONTINUED

Remuneration for new appointments
The Committee has determined that 
new Executive Directors will receive a 
compensation package in accordance 
with the terms of the Group’s approved 
Policy in force at the time of appointment.
The Committee has agreed the following 
principles that will apply when arranging 
a remuneration package to recruit new 
Executive Directors:
•	 The remuneration structure will 
be kept simple where practicable.
•	 The emphasis on linking pay with 
performance shall continue, with 
variable pay representing a significant 
component of the Executive Directors’ 
total remuneration package.
•	 Initial base salary will take into account the 
experience and calibre of the individual 
and their existing remuneration package. 
Where it is appropriate to offer a lower 
salary initially, a series of increases to the 
desired salary positioning may be given 
over subsequent years subject to 
individual performance.
•	 The structure of variable pay will be in 
accordance with Diploma’s approved 
Policy detailed above with a maximum 
aggregate variable pay opportunity of 
500% of salary for the CEO and 450% 
for other Executive Directors. Different 
performance measures may be set 
in the first year for the annual bonus, 
taking account of the responsibilities 
of the individual and the point in the 
financial year that the executive joined 
the Company.
•	 Benefits will generally be provided in 
accordance with the approved Policy, 
with relocation expenses/an expatriate 
allowance paid, if appropriate.
•	 In the case of an external recruitment, the 
Committee may also offer additional cash 
and/or share-based elements when it 
considers these to be in the best interests 
of Diploma and shareholders, to replace 
variable remuneration awards or 
arrangements that an individual has 
foregone in order to join the Group. 
This includes the use of awards made 
under section 9.3.2 of the UK Listing Rules. 
Any such payments would take account of 
the details of the remuneration foregone 
including the nature, vesting dates and 
any performance requirements attached 
to that remuneration and any payments 
would not exceed the expected value 
being forfeited.
•	 In the case of an internal appointment, 
any outstanding variable pay awarded in 
relation to the previous role will be allowed 
to pay out according to the terms of grant.
•	 For all new Executive Director 
appointments, the mandated shareholding 
requirement, deferral of annual 
performance bonus and the Holding 
Period for PSP awards will apply in 
accordance with the Policy and the 
relevant Plan rules.
•	 Fees for a new Chair or Non-Executive 
Director will be set in line with the 
approved Policy.
Committee discretion
The Committee operates the Annual 
Performance Bonus Plan and the 
Performance Share Plan (the Plans) in 
accordance with the relevant Plan rules and, 
where appropriate, the Listing Rules and 
HMRC legislation.
The Committee will exercise its powers in 
accordance with the terms of the relevant 
Plan rules. 
The Committee retains discretion over a 
number of areas relating to the operation 
and administration of the Plans. These 
include, but are not limited to:
•	 selecting the Executive Director 
participants and wider employee 
participation parameters for the annual 
bonus and PSP awards;
•	 timing of awards and grants as well as 
setting of performance criteria each year;
•	 determining the quantum of grants and/or 
payments (within the limits set out in the 
Policy Table);
•	 adjusting the constituents of the TSR 
comparator group;
•	 determining the extent of vesting based 
on the assessment of performance;
•	 overriding formulaic outcomes and 
amending payouts under the Annual 
Bonus Plan and for PSP should it 
determine that either it is not a fair 
reflection of the underlying performance 
of the business or in exceptional 
circumstances;
•	 applying or disapplying time prorating;
•	 dealing with leavers;
•	 discretion to waive or shorten the holding 
period for shares acquired under the PSP;
•	 discretion to retrospectively amend 
performance targets in exceptional 
circumstances, including making the 
appropriate adjustments required in 
certain circumstances (e.g. rights issues, 
corporate restructuring events, variation 
of capital and special dividends); and
•	 in respect of share awards, to adjust the 
number of shares subject to an award in 
the event of a variation in the share capital 
of the Company.
Policy in respect of external board 
appointments for Executive Directors
The Committee recognises that external 
Non-Executive Directorships may be 
beneficial for both the Company and 
Executive Director. At the discretion of the 
Board, Executive Directors are permitted to 
retain fees received in respect of any such 
Non-Executive Directorship.

Employee and post-employment 
shareholding requirements
The Committee has adopted shareholding 
requirements for Executive Directors, to 
encourage substantial long-term share 
ownership. These specify that, over a period 
of five years from the date of appointment, 
each Executive Director should build up and 
then retain a holding of shares with a value 
equivalent to 300% of base salary in the 
case of the CEO, and for other Executive 
Directors, to 250% of base salary (the MSR).
Vested PSP awards and deferred annual 
bonus payments which are issued as 
shares must be retained until the required 
shareholding (net of tax) level is reached.
As explained in the long-term incentive 
award section on page 104, Executive 
Directors are required to hold shares vesting 
under the PSP (net of tax) until the fifth 
anniversary of the grant (the Holding Period). 
The Holding Period continues to apply to 
post-cessation of employment except 
where cessation is by reason of death, if 
there is a change of control, or the 
Committee exercises its discretion.
In addition, a post-cessation shareholding 
requirement will apply being 50% of the 
MSR for two years after the termination date 
(or if less than the MSR, the value of shares 
held at the cessation date). Post-cessation 
holding continues to apply to shares granted 
under the PSP since the approval of the 
2020 Policy.
Chair and Non-Executive Directors
Recruitment and term
The Board aims to recruit Non-Executive 
Directors of a high calibre, with broad and 
diverse commercial, international, sectoral 
or other relevant experience. Non-Executive 
Directors are appointed by the Board on 
the recommendation of the Nomination 
Committee. Appointments of the Non-
Executive Directors are for an initial term 
of three years, subject to election by 
shareholders at the first AGM following 
their appointment and subject to annual 
re-election thereafter. The terms of 
engagement are set out in letters of 
appointment which can be terminated by 
either party serving three months’ notice.
Fees
The Non-Executive Directors are paid 
a competitive basic annual fee which 
is approved by the Board on the 
recommendation of the Chair and the 
Executive Directors. The Chair’s fee is 
approved by the Committee, excluding the 
Chair. Additional fees may also be payable 
for chairing a Committee of the Board, for 
acting as Senior Independent Director, or 
in respect of any other material additional 
responsibilities taken up. Fees are reviewed 
each year and take account of the fees paid 
in other companies of a similar size and 
complexity, the responsibilities of the role 
and the required time commitment.
If there is a temporary yet material increase 
in the time commitments for Non-Executive 
Directors, the Board may pay extra fees  
on a pro rata basis to recognise the 
additional workload.
The Non-Executive Directors are not eligible 
to participate in any of the Company’s share 
plans, incentive plans or pension schemes 
and there is no provision for payment in the 
event of early termination.

REMUNERATION POLICY CONTINUED

Provision 40 table
The following table summarises how the Remuneration Policy fulfils the factors set out in Provision 40 of the 2018 UK Corporate Governance Code.
Clarity
Remuneration arrangements should be 
transparent and promote effective engagement 
with shareholders and the workforce. 
Example: the structure of the Annual 
Performance Bonus Plan is completely 
based on financial metrics which align 
with published accounts.
The Committee is committed to providing open 
and transparent disclosures to shareholders, the 
workforce and other stakeholders with regard 
to executive remuneration arrangements.
The Committee determines the Remuneration 
Policy and agrees the remuneration of 
each Executive Director as well as the 
remuneration framework for other senior 
managers. The Company provides open 
and transparent disclosures of our Executive 
Directors’ remuneration arrangements including 
undertaking engagement with key shareholders 
when considering changes to Remuneration 
Policy. 
Simplicity
Remuneration structures should avoid 
complexity and their rationale and operation 
should be easy to understand.
Example: variable pay for Executive Directors is 
a simple Annual Bonus Plan and a Performance 
Share Plan.
Our remuneration arrangements for Executive 
Directors, as well as those throughout the 
organisation, are simple in nature and well 
understood by participants.
The structure for Executive Directors consists of 
fixed pay (salary, benefits, pension) and variable 
pay (annual bonus plan and a long-term incentive 
plan, the PSP).
Risk
Remuneration arrangements should ensure 
reputational and other risks from excessive 
rewards, and behavioural risks that can arise 
from target-based incentive plans, are 
identified and mitigated.
Example: the ROATCE underpin in the PSP 
reduces risk of low quality earnings.
Targets are reviewed to ensure they do 
not encourage excessive risk taking.
Malus and clawback provisions also apply to 
both the annual bonus and long-term incentive 
plans.
Members of the Committee are provided with 
regular briefings on developments and trends 
in executive remuneration.
Predictability
The range of possible values of rewards to 
individual Directors and any other limits or 
discretions should be identified and explained 
at the time of approving the Policy.
Example: variable pay maximums are set out 
in the Policy.
The potential value and composition of the 
Executive Directors’ remuneration packages at 
below threshold, target and maximum scenarios 
are provided in the relevant policy.
Proportionality 
The link between individual awards, the delivery 
of strategy and the long-term performance of 
the Company should be clear. Outcomes should 
not reward poor performance.
Example: 95% of budget must be achieved to 
trigger payment of Annual Performance Bonus; 
95% of budget only results in 5% payment.
Annual bonus payments and PSP awards 
require robust performance against 
challenging conditions that are aligned 
to the Company’s strategy.
The Committee has discretion to override 
formulaic results to ensure that they are 
appropriate and reflective of overall 
performance.
Alignment to culture
Incentive schemes should drive behaviours 
consistent with company purpose, values 
and strategy.
Example: one of the Diploma values is 
continuous improvement; continuous 
improvement is required each year to 
reach remuneration targets.
The variable incentive schemes and performance 
measures are designed to be consistent with the 
Group’s purpose, values and strategy.

Group, the Executive Directors will receive 100% of their maximum bonus for the year 
ended 30 September 2024. The following table summarises the performance assessment 
by the Committee in respect of 2024 with regard to the Group financial objectives and the 
bonus awarded to each of the Executive Directors:

In line with the Remuneration Policy, minimum shareholding requirement for the CEO is 
300% of base salary and 250% of base salary for other Executive Directors. In line with 
the Company’s Shareholding Policy, Johnny Thomson has met his minimum shareholding 
requirement (300%) and therefore his bonus for the year will be paid as cash. 50% of the 
2024 bonus for Chris Davies will be paid as cash and 50% net of tax will be deferred into 
shares until he reaches his minimum shareholding requirement (250%) set out in the Policy.
Bonus awards for year ended 30 September 2025
In the financial year beginning 1 October 2024, the Annual Performance Bonus Plan will be 
based on the following metrics: 50% will be based on adjusted operating profit, 20% will be 
based on revenue (both metrics measured on a constant currency basis), 25% will be based 
on free cash flow and the remaining 5% will be based on colleague engagement scores. The 
bonus maximum will increase to 200% for Johnny Thomson and 180% for Chris Davies. The 
financial performance targets set for the Annual Performance Bonus Plan for this year will be 
disclosed in next year’s Annual Report and Accounts, due to their commercial sensitivity.
Long-term incentive awards (audited)
The Company’s long-term incentive plan is the Performance Share Plan (PSP).
Performance conditions
Set out below is a summary of the performance conditions that apply to the PSP awards 
which vest in 2024 (PSP 2021), 2025 (PSP 2022), 2026 (PSP 2023) and 2027 (PSP 2024). 
Vesting of the PSP 2021 award is based 50% on growth in adjusted EPS and 50% on relative 
TSR performance. Vesting of the PSP 2022, PSP 2023 and PSP 2024 awards are based on 
75% growth in adjusted EPS and 25% on relative TSR performance. In order for any payment 
to be earned under the EPS element of awards, the Committee must consider that a 
satisfactory level of ROATCE performance has been achieved. The ROATCE underpin will 
be measured as the ROATCE in the third year of the performance condition and as defined 
in note 29.6 of the consolidated financial statements. 
EPS
The performance condition for PSP awards is that the average annual compound growth 
in the Company’s adjusted EPS, over the three consecutive financial years following the 
financial year immediately prior to the grant, must exceed the specified absolute figures. 
The performance targets are as follows:
Adjusted EPS growth (over three years)

ANNUAL REPORT ON REMUNERATION CONTINUED

Where the Company’s adjusted EPS performance is between these percentage bands, 
vesting of the award is on a straight-line basis. For the purposes of this condition, EPS is 
adjusted EPS as defined in note 29.3 to the consolidated financial statements, and this 
definition remains consistent with the definition of adjusted EPS approved by the 
Committee in previous years.
TSR
The performance condition compares the growth of the Company’s TSR over a three-year 
period to that of the companies in a recognised broad equity market index of which the 
Company is a member. PSP awards 2021 used the FTSE 250 Index (excluding Investment 
Trusts), as will also be the case for PSP awards 2022. PSP awards 2023 and 2024 will use 
the FTSE 100 Index (excluding Investment Trusts) which follows the Company’s promotion 
to the FTSE 100 Index in August 2023. The performance targets are as follows:

The PSP award granted on 29 November 2021 (PSP 2021) to Johnny Thomson, was subject 
to the performance conditions as set out on page 104 and independently assessed over a 
three-year period ended 30 September 2024. The outcome of this award is presented in

Long-term incentive plan – awards granted in the year (audited)
Johnny Thomson and Chris Davies received a grant of the PSP 2023 award on 27 November 
2023 respectively in the form of nil-cost options. This award was based on a share price 
of 3,342p, being the mid-market price of an ordinary share in the Company at close of 
business on the day immediately preceding the awards. The PSP 2023 award for Johnny 
Thomson was 300% of base salary and for Chris Davies was 250% of base salary.
Under normal circumstances, the options will not become exercisable until the performance 
conditions are determined after the end of the three-year measurement period which 
begins on the first day of the financial year in which the award is made and provided the 
participating Director remains in employment. The level of vesting is dependent on the 
achievement of specified performance criteria at the end of the three-year measurement 
period. The performance conditions for this award are set out on page 113.

Executive directors’ interests (audited)
In options over shares
In respect of nil-cost options granted under the PSP, the remuneration receivable by an 
Executive Director is calculated on the date that the options first vest. The remuneration of 
the Executive Directors is the difference between the amount the Executive Directors are 
required to pay to exercise the options to acquire the shares and the total value of the 
shares on the vesting date.
If the Executive Directors choose not to exercise the nil cost options on the vesting date 
(they may exercise the options at any time up to the day preceding the tenth anniversary of 
the date of grant), any subsequent increase or decrease in the amount realised will be due 
to movements in the underlying share price between the initial vesting date and the date of 
exercise of the option. This increase or decrease in value reflects an investment decision by 
the Executive Director and, as such, is not recorded as remuneration.
The nil-cost options outstanding at 30 September 2024 and the movements in the number 
of shares during the year are as follows:

Remuneration in context
Chief Executive pay ratio (unaudited)
The table below sets out the Chief Executive pay ratios as at 30 September 2024.
The ratios compare the single total figure of remuneration of the CEO with the equivalent 
figures for the lower quartile (P25), median (P50) and upper quartile (P75) UK employees. 
Option A has been used as it is the most statistically accurate method, considered best 
practice by the Government and investors, and is directly comparable to the CEO’s 
remuneration.
The employee data was measured on 30 September 2024, using the most up-to-date 
bonus estimates. The approach used was the same as the single total figure methodology 
with the exception that bonus estimates were used and colleagues who work part time were 
converted to full time equivalent and those who worked part of the year were annualised.

wider workforce pay and conditions is contained on page 106. The CEO is remunerated 
predominantly on performance-related elements (bonus and share awards), which have 
delivered strong returns.

ANNUAL REPORT ON REMUNERATION CONTINUED

The median CEO pay ratio has remained at a similar level to prior year (2024: 127:1; 2023: 
126:1). CEO pay has increased due to a base pay increase and higher share price 
appreciation whilst median total compensation for the UK workforce has also increased by 
8% and median base pay has also increased by 7% on prior year. In addition, this year we 
became an accredited Real Living Wage employer across our UK businesses (with the 
exception of R&G, where we are currently working towards accreditation).

Governance
Remuneration Committee
The Committee is chaired by Jennifer Ward and comprises the five Independent Non-
Executive Directors; David Lowden, Dean Finch, Geraldine Huse and Janice Stipp; served  
on the Committee throughout the year. The Group CEO, the Group CFO and the Group HR 
Director attend meetings at the invitation of the Committee to provide advice to help it 
make informed decisions. The Group Company Secretary attends meetings as Secretary  
to the Committee.
The Remuneration Committee Report
The Annual Report on Remuneration and the Chair’s Statement will continue to be subject 
to an advisory vote by shareholders at the 2024 AGM.
Remuneration principles and structure
The Committee has adopted remuneration principles which are designed to ensure that 
executive remuneration:
•	 is aligned to the business strategy and promotes the long-term success of the Company;
•	 supports the creation of sustainable long-term shareholder value;
•	 provides an appropriate balance between remuneration elements and includes 
performance-related elements which are transparent, stretching and rigorously applied;
•	 provides an appropriate balance between immediate and deferred remuneration; and
•	 encourages a high-performance culture by ensuring performance-related remuneration 
constitutes a substantial proportion of the remuneration package and by linking maximum 
payout opportunity to outstanding results.
These principles apply equally to those of senior management and align to those of the 
wider workforce.
Services from external advisors (unaudited)
The Committee appointed Willis Towers Watson (WTW) following a tender process in 2021 
and has continued to receive its remuneration advice from WTW. The fees are agreed in 
advance with the advisor, based on the scope of work. All advisors are selected by the 
Committee based on their technical expertise and independence. None of the advisors 
have any relationship with any Director and the Committee is satisfied that the services of 
advisors are independent, which it validates by checking that the advisors are not providing 
other services to the Company. Details are shown in the table below:

Financial 
Results and dividends
The profit for the financial year attributable 
to shareholders was £129.3m (2023: £117.7m). 
The Directors recommend a final dividend of 
42.0p (2023: 40.0p) per ordinary share, to 
be paid, if approved, on 31 January 2025. 
This, together with the interim dividend of 
17.3p (2023: 16.5p) per ordinary share, 
amounts to 59.3p for the year (2023: 56.5p).
The results are shown more fully in the 
audited consolidated financial statements 
on pages 132 to 178 and summarised in the 
Financial Review on pages 46 to 49.
Independent Auditors
Each of the persons who is a Director at 
the date of approval of this Annual Report 
and Accounts confirms that so far as the 
Director is aware, there is no relevant audit 
information of which the Company’s auditor 
is unaware; and the Director has taken all the 
steps that he/she ought to have taken as a 
Director in order to make himself/herself 
aware of any relevant audit information and 
to establish that the Company’s auditor is 
aware of that information. This confirmation 
is given and should be interpreted in 
accordance with the provisions of 
section 418 of the Companies Act 2006.
PricewaterhouseCoopers LLP (PwC) has 
expressed its willingness to continue in 
office as independent auditor and a 
resolution to reappoint PwC will be 
proposed at the AGM to be held on 
15 January 2025.
Directors’ assessment of going concern
The Directors continue to adopt the going 
concern basis in preparing the Annual 
Report and Accounts. Their assessment in 
reaching this conclusion is set out in the 
notes to the consolidated financial 
statements on page 168.
Statement of Directors’ responsibilities 
for preparing the financial statements
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 in 
conformity with the requirements of the 
Companies Act 2006 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).

DIRECTORS’ REPORT CONTINUED

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 
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 
United Kingdom 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, 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 Board of Directors 
confirm that, to the best of their knowledge:
•	 the Group financial statements, which 
have been prepared in accordance with 
UK-adopted International Accounting 
Standards give a true and fair view of the 
assets, liabilities, financial position and 
profit 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.

REPORT ON THE AUDIT OF  
THE FINANCIAL STATEMENTS
 
Opinion
In our opinion:
•	 Diploma PLC’s Group financial statements and Parent Company financial statements 
(the “financial statements”) give a true and fair view of the state of the Group’s and of 
the Parent Company’s affairs as at 30 September 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 Parent 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 
2024 (the “Annual Report”), which comprise: the Consolidated and Parent Company 
Statements of Financial Position as at 30 September 2024; the Consolidated Income 
Statement, the Consolidated Statement of Comprehensive Income, the Consolidated 
and Parent Company Statements of Changes in Equity and the Consolidated Cash Flow 
Statement for the year then ended; the Group and Parent Company Accounting Policies; 
and the notes to the financial statements.
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 the Audit Committee Report and Note 27 to the Group 
Financial Statements, we have provided no non-audit services to the Parent Company 
or its controlled undertakings in the period under audit.
Our audit approach

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.
The key audit matters below are consistent with last year.
Key audit matter
How our audit addressed the key audit matter
Valuation of the acquired intangibles for the 
Peerless and PAR Group acquisitions (Group)
 
Refer to page 175 Significant accounting 
estimates and critical judgements (Acquisition 
accounting) and Note 22 (Acquisitions and 
disposals of businesses) within the Group 
financial statements.
The Group acquired Peerless and PAR Group 
for a combined consideration of £269.5m (net 
of cash acquired). Acquired intangible assets 
of £75.2m were identified and recognised in 
respect of these acquisitions. The valuation 
of the acquired intangibles for these two 
acquisitions has been determined to be a 
significant risk due to its material quantum 
and the level of estimation associated with 
determination of fair values. 
The procedures we undertook to address 
the significant risk identified included:
•	 Validation of the mathematical accuracy of 
management’s models and appropriateness 
of the methodologies used to determine the 
fair values, with support from our internal 
valuation experts.
•	 Obtaining an understanding of the 
assumptions used to determine the value 
of acquired intangibles, and in particular 
considering the following key assumptions:
	
−Discount rates: We engaged our valuation 
experts to corroborate the reasonableness 
of the discount rates using comparable 
market data, for example discount rates 
of other companies in similar industries.
Key audit matter
How our audit addressed the key audit matter
We have identified a significant risk associated 
with the valuation of the intangibles due to the 
magnitude of the acquisitions, the significant 
level of estimation involved in determining the 
fair value of the acquired intangibles and their 
sensitivity to changes in key assumptions 
including discount rates, forecast revenue 
growth rates, and customer attrition rates. 
In considering such assumptions, there is 
an inherent level of estimation uncertainty 
and subjectivity.
	
−Forecast revenue growth rates: We 
compared the assumptions in respect of 
forecast revenue growth rates to historical 
trading experience and the actual trading 
performance of the businesses subsequent 
to the acquisition. In addition, we compared 
the forecasts used in the valuations to the 
Board approved budgets, comparable 
companies and industry reports.
	
−Customer attrition rates: We corroborated 
the attrition rate assumptions and forecast 
cash flows to underlying support. We 
compared the assumptions in respect of 
forecast cash flows to historical customer 
sales and we engaged our valuation 
experts to assist in the evaluation of 
the methodology used by management.
From the procedures performed we 
concluded that management’s estimate 
of the fair values of the acquired intangibles 
is materially appropriate.

Key audit matter
How our audit addressed the key audit matter
Carrying value of investments in subsidiaries 
and recoverability of intercompany 
receivables (Parent Company) 
Refer to the Parent Company Statement of 
Financial Position and Note D (“Investments”) 
within the Parent Company financial 
statements. 
At the balance sheet date, the Parent 
Company had investments in subsidiaries of 
£700.5m (2023: £372.4m) and intercompany 
receivables of £289.1m (2023: £246.9m).
The Parent Company’s accounting policy for 
investments and intercompany receivables is 
to hold them at cost less any accumulated 
impairment. Impairment of the intercompany 
receivables is calculated in accordance with 
IFRS 9 (Financial Instruments). Investments in 
subsidiaries are assessed for impairment in line 
with IAS 36 (Impairment of Assets). Given the 
inherent judgement in assessing both the 
carrying value of a subsidiary company and 
the expected credit loss of intercompany 
receivables, this was identified as a key 
audit matter.
 
 
 
In assessing whether the carrying value of the 
Parent Company’s investment in subsidiaries 
was supportable, we verified that the net asset 
positions of the individual investments were in 
excess of the carrying value of the investment 
in those subsidiaries. We also evaluated whether 
other areas of our audit work identified any 
indicators of impairment concerning the 
recoverability of the carrying value of those 
investments as of the balance sheet date. We 
have no issues to report in respect of this work.
With regards to the recoverability of intercompany 
receivables, we have obtained and audited 
management’s IFRS 9 assessment regarding the 
ability for the counterparty to settle the balances 
with liquid resources available at the balance sheet 
date taking into account other commitments.
We have no issues to report in respect of this 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 Parent Company, the accounting processes and controls, and the 
industry in which they operate.
The Group is structured as three core Sectors (Life Sciences, Seals and Controls) with 
operations primarily geographically located in Australia, Canada, the USA, the UK and 
Continental Europe. Within the aforementioned Sectors are a number of businesses/
management reporting components which are consolidated by Group management.
The Group financial statements are a consolidation of multiple reporting components 
representing the operating businesses within these three core Sectors. Our audit scope was 
determined by considering the significance of each component’s contribution to adjusted 
profit before tax and contribution to individual financial statement line items, with specific 
consideration given to obtaining sufficient coverage over significant audit risks and other 
areas of higher risk.
We identified 21 financial reporting components across nine countries for which we 
determined that full scope audits would need to be performed. Through our full scope 
audits, the audit of the consolidation and other audit procedures performed at a Group 
level, we have achieved coverage of 80% of the Group’s adjusted profit before tax and 
73% of the Group’s revenue, giving us the evidence we needed for our opinion on the Group 
financial statements as a whole. The reporting components, excluding those audited by the 
Group engagement team, were audited by twelve component teams.
Certain Parent Company account balances were included in scope for the audit of the 
Group financial statements. However, we determined that the Parent Company did not 
require a full scope audit of its complete financial information for the purposes of the 
audit of the Group financial statements.
Our audit procedures at the Group level included the audit of the consolidation, fair value 
adjustments and intangible asset valuations on acquisitions, goodwill and investment 
impairment assessments, UK pensions and certain tax procedures. The Group engagement 
team also performed the audit of the Parent Company and one UK component.
The impact of climate risk on our audit
As part of our audit we made enquiries of management to understand the process they 
have adopted to assess the extent of the potential impact of climate change risk on the 
financial statements and to support the disclosures made in relation to climate risk within 
the Strategic Report.
In addition to enquiries with management, we also read management’s experts report, 
which underpins the overall assessment of climate risk.
The Board has made commitments to achieve net zero carbon emissions across their 
value chain by 2045, with a 50% reduction in scope 1 & 2 emissions by 2030.
Management has assessed that there is no material impact on the financial reporting 
judgements and estimates arising from their considerations, consistent with previous 
assessments made by the Group.
INDEPENDENT AUDITORS’ REPORT TO THE MEMBERS OF DIPLOMA PLC CONTINUED
126
DIPLOMA PLC ANNUAL REPORT 2024
Strategic Report
Additional Information
Corporate Governance
Financial Statements

Using our knowledge of the business, we evaluated management’s risk assessment and 
related disclosures. In particular we have considered how climate risk would impact the 
assumptions made in the forecasts used in their goodwill impairment assessments and 
going concern analysis.
We also considered the consistency of disclosures in relation to climate change contained 
in the Strategic Report with the financial statements and our knowledge from our audit.
Our responsibility over other information is further described in the “Reporting on other 
information” section on our report. We have not been engaged to provide assurance over 
the accuracy of these disclosures.
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 - Parent Company
Overall materiality
£12.3m (2023: £10.8m).
£9.9m (2023: £6.1m).
How we  
determined it
Based on approximately 5% 
of adjusted profit before tax
Based on approximately 1% of total 
assets
Financial statements - Group
Financial statements - Parent Company
Rationale for 
benchmark applied
Based on the benchmarks 
used in the Annual Report, 
adjusted profit before tax is 
considered as the primary 
measure used by the 
shareholders in assessing the 
underlying performance of the 
Group. This benchmark 
excludes the impact of 
adjustments in respect of 
amortisation of acquired 
intangible assets, acquisition 
items, profit or loss on disposal 
of operations, and other costs.
This is a typical measure used by 
shareholders in assessing the 
performance of a holding Parent 
Company and a generally accepted 
auditing benchmark.
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 £450,000 and £10.5m. 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 £9.2m (2023: £8.1m) for the Group financial 
statements and £7.4m (2023: £4.6m) for the Parent 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 £612,500 (Group audit) (2023: £537,500) and £495,000 
(Parent Company audit) (2023: £305,000) as well as misstatements below those amounts 
that, in our view, warranted reporting for qualitative reasons.

Our evaluation of the directors’ assessment of the Group's and the Parent Company’s ability 
to continue to adopt the going concern basis of accounting included:
•	 Reviewing management’s going concern assessment to ensure it was based upon the 
latest Board approved forecasts and that the cashflow assumptions were consistent with 
our understanding of the outlook for the sectors and the wider market;
•	 Testing the mathematical accuracy of the model, including forecast compliance with 
covenants;
•	 Corroborating key model inputs to independent evidence obtained over the course 
of the audit;
•	 Discussing conclusions with management across the business, including sector heads, 
to ensure consistency and gain perspective on the developments within the business;
•	 Comparison of the prior year forecasts against current year actual performance to assess 
management’s ability to forecast accurately;
•	 Reviewing the latest signed financing agreements to validate covenants used in the 
modelling and the timing of debt maturities; and
•	 Reviewing management's severe but plausible scenario to ensure these appropriately 
reflect the risk of potential performance below forecast levels, and that there remains 
sufficient headroom both against covenant compliance and liquidity.
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 Parent 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 Parent 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 30 September 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 Parent 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 
Parent 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, included within the Corporate 
Governance section of the Annual Report 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 Parent 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 Parent 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 Parent 
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 
Parent 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 Parent 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 Parent 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 Parent 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 for preparing the 
financial statements, 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 Parent 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 Parent 
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 data protection laws (including 
GDPR) and health and safety, 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 UK Listing Rules, 
the Companies Act 2006, indirect and direct tax legislation and pension rules. 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 fraudulent journal entries to manipulate the financial performance and 
management bias in significant accounting estimates, in order to achieve management 
incentive scheme targets and market consensus. 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. Audit procedures performed by the 
Group engagement team and/or component auditors included:
•	 enquiring of Group and local management, including consideration of known or 
suspected instances of non-compliance with laws and regulations and fraud, and 
review of internal audit reports;
•	 enquiring of entity staff in tax and compliance functions to identify any instances  
of non-compliance with laws and regulations;
•	 reviewing minutes of meetings of those charged with governance;
•	 challenging assumptions and judgements made by management in their accounting 
estimates (due to the risk of management bias), including the inventory provision and 
accounting for acquisitions;
•	 incorporating elements of unpredictability into our work;
•	 reviewing financial statement disclosures and testing to supporting documentation 
to assess compliance with applicable laws; and
•	 auditing the risk of management override of controls, including through testing 
certain journal entries and other adjustments for appropriateness.
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 Parent 
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.

3. BUSINESS SECTOR ANALYSIS  
The Chief Operating Decision Maker (CODM) for the purposes of IFRS 8 is the CEO. The financial performance of the business Sectors is reported to the CODM on a monthly basis and 
this information is used to allocate resources on an appropriate basis. 
For management reporting purposes, the Group is organised into three main reportable business Sectors: Controls, Seals and Life Sciences. These Sectors are the Group’s operating 
segments as defined by IFRS 8 and form the basis of the primary reporting format disclosures below. The CODM reviews discrete financial information at this operating segment level. 
The principal activities of each of these Sectors are described in the Strategic Report on pages 28 to 45. Sector revenue represents revenue from external customers; there is no 
material inter-Sector revenue. Sector results, assets and liabilities include items directly attributable to a Sector, as well as those that can be allocated on a reasonable basis.

The tax adjustment in the Consolidated Income Statement of £15.3m (2023: £14.7m) 
reflects the tax effect of the acquisition related and other charges, and acquisition related 
finance charges. 
The Group earns its profits in the UK and overseas. The Group prepares its consolidated 
financial statements for the year to 30 September and the statutory tax rate for  
UK corporation tax in respect of the year ended 30 September 2024 was 25.0%  
(2023: 22.0%) and this rate has been used for tax on profit in the above reconciliation.  
The Group’s effective tax rate on adjusted profit remains consistent with the prior year at 
24% (2023: 24%). This is reflective of the geographic mix of profits and the statutory tax 
rates in the jurisdictions in which we operate. The UK deferred tax assets and liabilities at 
30 September 2024 have been calculated by reference to the UK corporation tax rate of 
25.0% (2023: 25.0%). 
At 30 September 2024, the Group had outstanding tax liabilities of £22.9m  
(2023: £16.6m). These amounts are expected to be paid within the next financial year.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
FOR THE YEAR ENDED 30 SEPTEMBER 2024 CONTINUED
During 2021, the OECD published a framework for the introduction of a global minimum 
effective tax rate of 15%, applicable to large multinational groups. The legislation 
implementing these ‘Pillar Two’ rules in the UK was substantively enacted on 20 June 2023 
and will apply to the Group from the financial year ending 30 September 2025 onwards. 
We have applied the temporary exception under IAS 12 from the requirement to recognise 
and disclose deferred taxes arising from the implementation of the Pillar Two rules.   
The OECD has issued guidance on safe harbours and penalty relief. This includes a 
Transitional Country-by-Country Safe Harbour (‘TCSH’), which allows multinationals to 
avoid detailed calculations for a jurisdiction if they meet certain criteria. Based on these 
rules, the most recently filed country-by-country report and the effective tax rates in most 
jurisdictions in which the Group operates being above 15% we do not expect the Pillar Two 
legislation to have a material effect on the financial statements of the Group.

The Directors have proposed a final dividend in respect of the current year of 42.0p per 
share (2023: 40.0p), which will be paid on 31 January 2025 subject to approval by 
shareholders at the Annual General Meeting (AGM) on 15 January 2025. The total dividend 
for the current year, subject to approval of the final dividend, will be 59.3p per share 
(2023: 56.5p). 
The Diploma PLC Employee Benefit Trust holds 60,708 (2023: 67,431) shares, which are 
ineligible for dividends. 
9. EARNINGS PER SHARE 
Basic and diluted earnings per share 
Basic earnings per ordinary 5p share is calculated on the basis of the weighted average 
number of ordinary shares in issue during the year of 134,020,566 (2023: 129,675,581) and 
the profit for the year attributable to shareholders of £129.3m (2023: £117.7m). Basic 
earnings per share is 96.5p (2023: 90.8p). Diluted earnings per share is 96.1p (2023: 90.4p) 
and is based on the average number of ordinary shares (which includes any potentially 
dilutive shares) of 134,494,807 (2023: 130,260,868). 
Further description of the Company’s share capital is set out in note (F) to the Parent 
Company Financial Statements on page 178. 
Adjusted earnings per share 
Adjusted EPS, which is defined in note 29.3, is 145.8p (2023: 126.5p).

The Group tests goodwill for impairment at least once a year. For the purposes of 
impairment testing, goodwill is allocated to each of the Group’s three cash-generating 
units (CGUs), which are the three operating Sectors: Controls, Seals, and Life Sciences. 
This represents the lowest level within the Group at which goodwill is monitored by 
management and reflects the Group’s strategy of acquiring businesses to drive synergies 
across a Sector, rather than within an individual business. The impairment test requires a 
‘value in use’ valuation to be prepared for each Sector using discounted cash flow 
forecasts. The cash flow forecasts are based on a combination of annual budgets 
prepared by each business and the Group’s strategic plan. 
The key assumptions used to prepare the cash flow forecasts relate to operating margins, 
revenue growth rates, the discount rates and climate related risks. The operating margins 
are assumed to remain sustainable, which is supported by historical experience. Revenue 
growth rates generally approximate to the average rates for the markets in which the 
business operates, unless there are particular factors relevant to a business. The cash flow 
forecasts use the budgeted figures for FY25, and then the three-year strategy cash flows 
for the next two years. From year four onwards a long-term growth rate of 2% is utilised. 
The cash flow forecasts are discounted to determine a current valuation using market 
derived pre-tax discount rates; Controls 9.7% (2023: 10.1%), Seals 10.1% (2023: 10.2%) 
and Life Sciences 9.4% (2023: 10.1%). The equivalent post-tax discount rates for FY24  
are: Controls 9.6% (2023: 10.0%), Seals 10.0% (2023: 10.1%) and Life Sciences 9.3%  
(2023: 10.0%).  
These rates are based on the characteristics of lower risk, non-technically driven, 
distribution businesses operating generally in well-developed markets and with robust 
capital structures.  
Based on the criteria set out above, no impairment in the value of goodwill in the CGUs 
was identified. 
The Directors have also carried out sensitivity analyses on the key assumptions noted 
above to determine whether a ‘reasonably possible adverse change’ in any of these 
assumptions, including the net financial impact of climate-related risks and opportunities, 
would result in an impairment of goodwill. The analysis indicates that a ‘reasonably 
possible adverse change’ would not give rise to an impairment charge to goodwill in any 
of the three CGUs.

No deferred tax has been provided on unremitted earnings of overseas Group companies 
as the Group controls the dividend policies of its subsidiaries. Unremitted earnings may be 
liable to overseas withholding tax (after allowing for double taxation relief) if they were to 
be distributed as dividends. The aggregate amount for which deferred tax has not been 
recognised in respect of unremitted earnings from overseas businesses of £227.9m (2023: 
£208.7m) was £11.5m (2023: £10.5m).

19. FINANCIAL INSTRUMENTS 
The Group’s overall management of financial risks is carried out by a central treasury team under policies and procedures which are reviewed and approved by the Board. The treasury 
team identifies, evaluates and, where appropriate, hedges financial risks in close co-operation with the Group’s operating businesses. The treasury team does not undertake 
speculative foreign exchange dealings for which there is no underlying exposure. 
The Group’s principal financial instruments, other than a number of forward foreign currency contracts, comprise cash and short-term deposits, trade and other receivables and trade 
and other payables, borrowings and other liabilities. Trade and other receivables and trade and other payables arise directly from the Group’s day-to-day operations. 
The financial risks to which the Group is exposed are those of credit, liquidity, foreign currency, interest rate and capital management. An explanation of each of these risks, how the 
Group manages these risks and an analysis of sensitivities is set out below. 
a) Credit risk 
Credit risk is the risk of financial loss to the Group if a customer or counterparty to a financial instrument fails to meet its contractual obligations; this arises principally from the Group’s 
trade and other receivables from customers and from cash balances (including deposits) held with financial institutions. 
The Group is exposed to customers ranging from government-backed agencies and large public and private wholesalers, to small privately-owned businesses and the underlying local 
economic risks vary throughout the world. Trade receivable exposures are managed locally in the operating units where they arise and credit limits are set as deemed appropriate for 
each customer. 
The Group establishes a loss allowance that represents its estimate of potential losses in respect of specific trade and other receivables where it is deemed that a receivable may not 
be recoverable (see below) and considers factors which may impact risk of default. Where appropriate, we have grouped these receivables with the same overall risk characteristics. 
When the receivable is deemed irrecoverable, the provision is written off against the underlying receivable. During the year, the Group had no significant unrecoverable trade 
receivables. 
Exposure to counterparty credit risk with financial institutions is controlled by the Group treasury team which establishes and monitors counterparty limits. Centrally managed funds are 
invested entirely with counterparties whose credit rating is ‘A’ or better. There are no significant concentrations of credit risk. There has been no historical or expected credit loss on 
cash and cash equivalents.

There is no material difference between the book value of the financial assets and their fair 
value at each reporting date. An analysis of the ageing and currency of trade receivables 
and the associated loss allowance is set out in note 16. An analysis of cash and cash 
equivalents is set out in note 18. 
Impairment of financial assets 
The Group applies the IFRS 9 simplified approach to measuring expected credit  
losses which uses a lifetime expected loss allowance for all trade receivables and  
accrued income. 
The expected loss rates are based on the payment profiles of revenues over a period of 
60 months ended 30 September 2024 and the corresponding historical credit losses 
experienced within this period. The historical loss rates are adjusted to reflect current and 
forward-looking information including macroeconomic factors by obtaining and reviewing 
relevant market data affecting the ability of the customers to settle the receivables. 
The Group has identified the current health of the economy (such as market interest rates 
and growth rates), of the countries in which it sells its goods to be the most relevant 
factors and accordingly adjusts the historical loss rates based on expected changes in 
these factors. An increase in credit risk is presumed if a debtor is more than 30 days past 
due in making a contractual payment. Where objective evidence exists that a trade 
receivable balance may be impaired, provision is made for the difference between its 
carrying amount and the present value of the estimated cash that will be recovered. 
Evidence of impairment may include factors such as a change in credit risk profile of the 
customer, the customer being in default on a contract, or the customer entering insolvent 
administration proceedings. All significant balances are reviewed individually on a monthly 
basis for evidence of impairment. 
b) Liquidity risk 
Liquidity risk is the risk that the Group will not be able to meet its financial obligations as 
they fall due. The Group continually monitors net cash and forecasts cash flows to ensure 
that sufficient resources are available to meet the Group’s requirements in the short, 
medium and long term.  
The Group has a multi-currency revolving credit facility agreement (RCF) with an 
aggregate principal amount of £555.0m. In July 2024, the Group exercised the first of 
 two 12-month extension options for the RCF, which was accepted by banks committing 
£515.0m of the aggregate total. The RCF is now contractually due to expire across July 
2028 (£40.0m) and July 2029 (£515.0m). A 24-month extension option in respect of 
£40.0m and a second 12-month extension option in respect of £515.0m can be exercised 
in July 2025. 
During the year, the Group issued US private placement notes for an aggregate principal 
amount of £207.9m (€250.0m) with maturities of 7 years (€75.0m), 10 years (€100.0m) 
and 12 years (€75.0m) and for an aggregate principal amount of £111.9m ($150.0m) with 
maturities of 8 years ($100.0m) and 11 years ($50.0m).  
Additionally, compliance with debt covenants is monitored regularly and during 2024 all 
debt covenant tests were complied with. The applicable financial covenants are interest 
cover and leverage, whereby EBITDA must be at least 4x net finance charges; and the ratio 
of net debt to EBITDA must not exceed 3.5x (as defined by the relevant debt agreement). 
The Group’s debt facilities are subject to interest at a mix of fixed and variable rates.  
As at 30 September 2024 fixed rate debt was 66% of total debt. 
The undrawn committed facilities available at 30 September are as follows:

c) Currency risk 
The Group’s principal currency risk comprises translational and transactional risk from its 
exposure to movements in US dollars, Canadian dollars, Australian dollars and Euros.  
The transactional exposure arises on trade receivables, trade payables and cash and  
cash equivalents and these balances are analysed by currency in notes 16, 17  
and 18, respectively. 
The Group holds forward foreign exchange contracts in certain of the Group’s businesses 
to hedge forecast transactional exposure to movements in the US dollar, Canadian dollar, 
Australian dollar, Euro and UK Sterling. These forward foreign exchange contracts are 
classified as cash flow hedges and are stated at fair value. The notional value of forward 
exchange contracts used as hedges as at 30 September 2024 was £66.5m (2023: 
£68.6m). The net fair value of forward exchange contracts used as hedges at 30 
September 2024 was £1.2m liability (2023: £0.1m asset). 
For hedges of foreign currency transactions, the Group enters into hedge relationships 
where the critical terms of the hedging instrument match with the terms of the hedged 
item. 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 derivative 
counterparty. The amount removed from Other Comprehensive Income as a result of the 
maturing of the hedged instrument and taken to the Consolidated Income Statement in 
cost of sales during the year was £0.5m debit (2023: £1.3m debit). The change in the fair 
value of cash flow hedges taken to Other Comprehensive Income during the year was 
£0.8m debit (2023: £0.1m credit). 
For foreign currency translational exposures, the Group employs net investment hedge 
accounting where appropriate to mitigate these risks. The Group has designated US 
private placement notes denominated in USD and EUR, with carrying values of $150m 
(2023: $nil) and €250m (2023: €nil) respectively, as net investment hedges for foreign 
currency net assets. The hedge ratio was 1:1. Ineffectiveness may arise if the hedge ratio is 
not adjusted to reflect changes in the relationship between the hedged item and the 
hedging instrument. The change in the carrying value of borrowings as a result of 
exchange rate differences that was recognised in Other Comprehensive Income during 
the year was a gain of £7.2m (2023: £nil). 
Management considers that the most significant foreign exchange risk relates to the  
US dollar, Canadian dollar and Euro. The Group’s sensitivity to a 10% strengthening in  
UK sterling against each of these currencies (with all other variables held constant)  
is as follows:

d) Interest rate risk 
Interest rate risk is the risk that changes in interest rates will affect the Group’s results.  
The Group’s interest rate risk arises primarily from its cash funds and borrowings. 
The Group used interest rate swaps to hedge a proportion of external borrowings until 31 
March 2024. These interest rate swaps were designated as cash flow hedges and stated 
at fair value. The swaps matured before 30 September 2024 and the notional amount was 
therefore £nil (2023: £163.9m). Similarly, the net fair value of these swaps as at 30 
September 2024 was £nil (2023: £2.3m asset). The interest rate swaps matured during the 
year and the amount removed from Other Comprehensive Income and taken to the 
Consolidated Income Statement during the year was £1.8m debit (2023: £2.5m debit). 
The change in fair value of cash flow hedges taken to Other Comprehensive Income during 
the year was £0.5m debit (2023: £1.7m credit).  
The Group’s financial assets that are subject to interest rate fluctuations are cash deposits 
held in the UK and overseas. These are held on a short-term basis at floating rates or 
overnight rates and are based on the relevant UK base rate, or equivalent rate. Surplus 
funds are pooled and deposited with commercial banks that meet the credit criteria 
approved by the Board, for periods of between one and six months at rates that are 
generally fixed by reference to the relevant UK base rate, or equivalent rate.  
The Group’s financial liabilities that are subject to interest rate fluctuations are overdrafts 
and the Group’s RCF that bear interest at market rates according to the currency of 
the borrowing. 
Longer-term funding is provided by the Group’s US private placement notes, completed 
in March 2024 and August 2024 and bear interest at fixed rates as described in note 25. 
A movement of 1% in interest rates would have a ca. £1.7m (2023: £2.4m) impact on 
adjusted profit before tax. 
e) Fair values 
There are no material differences between the book value of financial assets and liabilities 
and their fair value. The basis for determining fair values are as follows: 
Derivatives 
Forward exchange contracts are designated as level 2 assets in the fair value hierarchy 
under IFRS 7 and valued at year end forward rates, adjusted for the forward points to the 
contract’s value date with gains and losses taken to equity. No contract’s maturity date is 
greater than 24 months from the year end. 
For hedges of foreign currency transactions, the Group enters into hedge relationships 
where the critical terms of the hedging instrument match with the terms of the hedged 
item, 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 
derivative counterparty. 
Interest rate swap contracts are designated as level 2 assets (in the ‘fair value hierarchy’) 
and valued at year end as the net present value of the cash flows using current forward 
market interest rates, with gains and losses taken to equity.  
The Group enters into interest rate swaps that have similar critical terms as the hedged 
item, such as reference rate, payment dates, maturities and notional amount. The Group 
has established a hedge ratio of 1:1 for the hedging relationships as the underlying risk of 
the interest rate swap is identical to the hedged risk component. The hedge 
ineffectiveness can arise from differences in timing or cash flows of the hedged item and 
hedging instrument, or the counterparties’ credit risk differently impacting the fair value 
movements of the hedging instrument and hedged item.  
Trade and other receivables/payables 
The book value of trade and other receivables/payables is deemed to reflect the  
fair value. 
Borrowings 
The fair value of borrowings under the RCF equates to the book value. 
The fair value of the Group’s US private placement notes is estimated to be £337.5m.  
The fair value is estimated by discounting the future contracted cash flows using readily 
available market data and represents a level 2 measurement (in the ‘fair value hierarchy’). 
Other liabilities 
The carrying amount of the items included within note 20 represents a discounted value of 
the expected liability which is deemed to reflect the fair value and are designated as level 
3 assets (in the ‘fair value hierarchy’).

f) Capital management risk 
The Group’s capital structure comprises the retained earnings reserve (£478.2m), cash 
funds (£60.2m) and medium and long-term borrowing facilities (£479.8m). The Group’s 
objective when managing capital is to safeguard its ability to continue as a going concern 
and to maintain robust capital ratios to support the development of the business including 
executing acquisitions and providing strong returns to shareholders.

minority interests of 10% in M Seals, 5% in Techsil, 2% in R&G Fluid Power Group and 5%  
in Pennine Pneumatic Services. 
At 30 September 2024, the estimate of the financial liability to acquire these outstanding 
minority shareholdings was reassessed by the Directors, based on their current estimate 
of the future performance of these businesses and to reflect foreign exchange rates at  
30 September 2024.  
This led to a remeasurement of the options and the liability decreased by £0.2m (2023: 
£1.8m increase) reflecting a revised estimate of the future performance of these 
businesses and foreign exchange. In aggregate, £0.2m has been credited to the 
Consolidated Income Statement (2023: £1.8m debit).

22. ACQUISITIONS AND DISPOSALS OF BUSINESSES 
Acquisition of Plastic and Rubber Group Holdings Limited 
On 30 April 2024, the group completed the acquisition of 98% of the shares in Plastic and 
Rubber Group Holdings Limited (PAR Group), a supplier of specialist seals and gaskets. 
The total investment, net of cash acquired, was £36.7m.  
The provisional fair value of PAR Group's net assets acquired excluding acquisition 
intangibles, related deferred tax and cash is £4.9m following net fair value adjustments of 
£1.1m. The principal fair value adjustments relate to a net increase in inventory of £0.3m, 
fair value uplift of property, plant and equipment of £1.0m and recognition of previously 
unrecognised liabilities of £0.2m. 
Acquisition expenses of £0.7m have been recognised in respect of this transaction in the 
financial year. 
From the date of acquisition to 30 September 2024, PAR Group contributed £5.3m to 
revenue and £2.2m to adjusted operating profit. Had it been acquired at the beginning of 
the financial year, it would have contributed on a pro forma basis £12.7m to revenue and 
£5.2m to adjusted operating profit. However, these amounts should not be viewed as 
indicative of the results that would have occurred if PAR Group had been completed at  
the beginning of the year.   
Acquisition of Peerless Aerospace Fastener LLC 
On 01 May 2024, the Group completed the acquisition of 100% of the shares in Peerless 
Aerospace Fastener LLC (Peerless), a value-add supplier of specialty fasteners to the 
Aerospace and Defence markets in the US and Europe. The total investment, net of cash 
acquired, was £243.3m. The provisional fair value of Peerless' net assets acquired 
excluding acquisition intangibles, related deferred tax and cash is £63.5m following net  
fair value adjustments of £4.2m. The goodwill represents the technical expertise of the 
acquired workforce and the opportunity to leverage any revenue synergies through cross-
selling within other businesses. The principal fair value adjustments relate to a fair value 
uplift related to property, plant and equipment of £5.2m, net increase in inventory of 
£15.2m, increase in provisions held against trade receivables of £1.6m and a recognition of 
previously unrecognised liabilities of £14.6m. The fair value of acquired trade receivables is 
£17.7m, of which the gross contractual amount due is £19.7m, with a loss allowance of 
£2.0m recognised on acquisition.  
Acquisition expenses of £3.1m have been recognised in respect of this transaction in the 
financial year. From the date of acquisition to 30 September 2024, Peerless contributed 
£54.1m to revenue and £25.0m to adjusted operating profit. Had it been acquired at the 
beginning of the financial year, it would have contributed on a pro forma basis £129.9m to 
revenue and £59.9m to adjusted operating profit. However, these amounts should not be 
viewed as indicative of the results that would have occurred if Peerless had been 
completed at the beginning of the year. 
Other acquisitions 
The Group completed five other acquisitions in the year. This comprised the trade and 
assets of Cable and Tubing Solutions Limited (CTS) (20 November 2023) and 100% of the 
share capital of Technisil GMBH (Technisil) (28 February 2024) and 98% of the share capital 
of Fast Gaskets and Parts Limited (Fast Gaskets) (04 October 2023), Abbey Hose 
Company Limited (Abbey Hose) (22 December 2023) and PTFEFLEX Ltd (PTFE)  
(10 May 2024). The combined initial consideration for these acquisitions was £9.7m,  
net of cash acquired of £1.3m. Deferred consideration with a fair value of £3.6m is payable 
based largely on the performance of the businesses in the period subsequent to  
their acquisitions.  
Acquisition expenses of £0.3m have been recognised in respect of these transactions 
completed in the financial year. 
The provisional fair value of the total net assets acquired excluding intangibles, related 
deferred tax and cash is £1.1m.

The Group has a multi-currency revolving credit facility agreement (RCF) with an 
aggregate principal amount of £555.0m. In July 2024, the Group exercised the first of  
two 12-month extension options for the RCF, which was accepted by banks committing 
£515.0m of the aggregate total. The RCF is now contractually due to expire across July 
2028 (£40.0m) and July 2029 (£515.0m). A 24-month extension option in respect of 
£40.0m and a second 12-month extension option in respect of £515.0m can be exercised 
in July 2025. 
Borrowings include capitalised borrowing fees of £5.1m (2023: £4.3m).  
The RCF is subject to interest at variable rates while the private placement notes are at 
fixed rates. At 30 September 2024, fixed rate debt was 66% of total debt. 
As at 30 September 2024 the Group’s net debt is £419.6m (2023: £254.7m) and excludes 
lease liabilities of £72.3m (2023: £80.2m). 
At 30 September 2024, the Group’s Net Debt/EBITDA ratio is 1.3x, as illustrated in

26. RETIREMENT BENEFIT ASSETS AND OBLIGATIONS 
The Group maintains two pension arrangements which are accounted for under IAS 19 
(Revised) (Employee Benefits). The principal arrangement is the defined benefit pension 
scheme in the UK, maintained by Diploma Holdings PLC (DHPLC) and called the Diploma 
Holdings PLC UK Pension Scheme (the Scheme). This Scheme provides benefits based on 
final salary and length of service on retirement, leaving service or death and has been 
closed to further accrual since 5 April 2000. 
The second and smaller pension arrangement is operated by Kubo, a business based in 
Switzerland and provides benefits on retirement, leaving service or death for the 
employees of Kubo in accordance with Swiss law. The Kubo pension scheme, which is 
included in liabilities held for sale, is a defined contribution-based scheme, which for 
technical reasons, is required under UK-adopted International Accounting Standards to be 
accounted for in accordance with IAS 19 (Revised). 
The amount of pension asset/(deficit) included in the Consolidated Statement of Financial 
Position in respect of these two pension arrangements is:

Diploma Holdings PLC UK Pension Scheme 
The Scheme provides benefits based on final salary and length of service on retirement, 
leaving service or death. Any defined contribution schemes operated by DHPLC are not 
included in these disclosures. 
 
The Scheme is managed by a board of Trustees appointed in part by DHPLC and in part 
from elections by members of the Scheme. The Trustees have responsibility for obtaining 
valuations of the fund, administering benefit payments and investing the Scheme's assets. 
The Trustees delegate some of these functions to their professional advisors where 
appropriate. 
 
On 28 September 2018, the Trustees completed a Buy-In of the pensioner liabilities in the 
Scheme with Just Retirement Limited. The Scheme paid £12.3m to Just Retirement Limited 
on 28 September 2018 to fund 95% of the Buy-In premium and £0.7m was paid on 22 
October 2018 to fund the remaining 5% of the premium. 
 
On 26 March 2024, the Trustees completed a Buy-In of the remaining pensioner liabilities 
in the Scheme with Just Retirement Limited. The Scheme paid £25.1m to Just Retirement 
Limited to fund 100% of the Buy-In premium. 
 
In accordance with the schedule of contributions currently in force following the Buy-In, 
DHPLC does not expect to make any contributions in the year to 30 September 2025. 
 
There were no plan amendments, curtailments or settlements during the period.

Risk mitigation strategies 
Individual annuity policies are held in respect of some historic pensioners. As noted  
above, the Scheme’s liabilities are now secured with an insurer. Therefore the key risk that 
remains within the Scheme is the risk of insurer default (although this risk is expected  
to be very low). 
The Scheme has no other asset-liability strategies in place.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
FOR THE YEAR ENDED 30 SEPTEMBER 2024 CONTINUED
The Group is aware of a UK High Court legal ruling in June 2023 between Virgin Media 
Limited and NTL Pension Trustees II Limited, which decided that certain historic rule 
amendments were invalid if they were not accompanied by actuarial certifications. The 
ruling was subject to an appeal with a judgment delivered on 25 July 2024. The Court of 
Appeal unanimously upheld the decision of the High Court and concluded that the pre-
April 2013 conditions applied to amendments to both future and past service. Whilst this 
ruling was in respect of another scheme, this judgment will need to be reviewed for its 
relevance to the Scheme. As the Court of Appeal has only just delivered its verdict, the 
Scheme pension advisors have not yet completed any analysis and therefore no 
adjustments have been made to the Consolidated Financial Statements as at 30 
September 2024. 
Effect of the Scheme on the Group’s future cash flows 
DHPLC is required to agree a schedule of contributions with the Trustees of the Scheme 
following each triennial actuarial valuation. Following the triennial actuarial valuation carried 
out as at 30 September 2022, DHPLC had agreed to contribute £0.6m in cash to the 
Scheme annually increasing at 2% per year. The current year contribution was £0.5m and 
ceased from April 2024 onwards following the completion of the purchase of the Buy-In 
policy on 26 March 2024. 
The Kubo Pension Scheme (the Kubo Scheme) 
In accordance with Swiss law, Kubo’s pension benefits are contribution based with the 
level of benefits varying according to category of employment. Swiss law requires certain 
guarantees to be provided on such pension benefits. Kubo finances its Swiss pension 
benefits through the ASGA Pensionskasse, a multi-employer plan of non-associated 
companies which pools risks between participating companies. Set out below is a 
summary of the key features of the Kubo Scheme which has been included in liabilities 
held for sale.

29. ALTERNATIVE PERFORMANCE MEASURES  
The Group reports under UK‑adopted International Accounting Standards (UK-adopted 
IAS) and references alternative performance measures where the Board believes that they 
help to effectively monitor the performance of the Group and support readers of the 
Financial Statements in drawing comparisons with past performance. Certain alternative 
performance measures are also relevant in calculating a meaningful element of Executive 
Directors’ variable remuneration and our debt covenants. Alternative performance 
measures are not considered to be a substitute for, or superior to, UK-adopted IAS 
measures. The definitions of the alternative performance measures and the comparisons 
to their closest UK-adopted IAS measures can be found on pages 183 to 184. 
29.1 Revenue growth  
As a multi-national group of businesses which trades in a large number of currencies, and 
acquires and sometimes disposes of companies, organic growth is a key performance 
measure and is referred to throughout our reporting. The Board believes that this allows 
users of the financial statements to gain a better understanding of the Group’s 
performance.

1 The impact of acquisitions is the revenue of the acquiree prior to the acquisition by Diploma for the comparable 
year at prior year exchange rates. The impact of disposals is the removal of the revenue of the disposed entity in 
the comparable post disposal period at prior year exchange rates. 
2 Organic growth measures the change in revenue compared to the prior year, at prior year exchange rates.  
For acquisitions, this includes incremental revenues generated under Diploma’s ownership compared to the 
revenue in the same period prior to acquisition, at prior year exchange rates. 
3 Exchange rates movements are assessed by retranslating current year reported values at prior year  
exchange rates. 
29.2 Adjusted operating profit and adjusted operating margin 
Adjusted operating profit is the operating profit before adjusting items that would 
otherwise distort operating profit, being amortisation of acquisition intangible assets  
or goodwill, acquisition expenses, post-acquisition related remuneration costs and 
adjustments to deferred consideration, the costs of a significant restructuring or 
rationalisation and the profit or loss relating to the sale of businesses. These are  
treated as adjusting items (referred to as acquisition related and other charges) as 
 they are considered to be significant in nature and/or quantum and where treatment  
as an adjusting item provides all our stakeholders with additional useful information to  
assess the year-on-year trading performance of the Group on a like-for-like basis. 
Adjusted operating margin is the Group’s adjusted operating profit divided by the  
Group’s reported revenue.

operating profit is given below:

Adjusted earnings per share (adjusted EPS) is calculated as the total of adjusted profit 
before tax, less income tax costs, but including the tax impact on the items included in the 
calculation of adjusted profit, less profit/(loss) attributable to minority interests, divided by 
the weighted average number of ordinary shares in issue during the year of 134,020,566 
(2023: 129,675,581), as set out in note 9. The Directors believe that adjusted EPS provides 
an important measure of the earnings capacity of the Group.

29.4 Free cash flow and free cash flow conversion 
Free cash flow is defined as net cash flow from operating activities, less net capital 
expenditure on tangible and intangible assets, and including proceeds received  
from property, plant and equipment disposals, but before expenditure on business 
combinations/investments (including any pre-acquisition debt like items such as  
pensions or tax settled post-acquisition) and proceeds from business disposals, 
borrowings received to fund acquisitions, net proceeds from issues of share capital  
and dividends paid to both minority shareholders and the Company’s shareholders.  
‘Free cash flow conversion’ reflects free cash flow as a percentage of adjusted earnings. 
The Directors believe that free cash flow gives an important measure of the cash flow  
of the Group, available for future investment or distribution to shareholders.

Leverage is net debt, defined as cash and cash equivalents and borrowings translated  
at average exchange rates for the reporting period, divided by EBITDA as defined in  
the Group’s external facilities covenants, which is the Group’s adjusted operating profit 
adjusting for depreciation and amortisation of tangible and other intangible assets, the 
share of adjusted operating profit attributable to minority interests and the annualisation 
of EBITDA for acquisitions and disposals made during the financial year, excluding the 
impact of IFRS 16 (Leases). The Directors consider this metric to be an important measure 
of the Group’s financial position, as well as a key covenant metric.

29.6 Trading capital employed and ROATCE 
Trading capital employed is defined as net assets less cash and cash equivalents and 
retirement benefit assets, after adding back borrowings (other than lease liabilities), 
deferred tax, retirement benefit obligations and net acquisition liabilities in respect of 
future purchases of minority interests, deferred consideration payable on acquisitions, and 
acquisition receivables in respect of previously completed disposals. Adjusted trading 
capital employed is reported as being trading capital employed plus goodwill and 
acquisition related charges previously charged to the income statement (net of deferred 
tax on acquisition intangible assets) and retranslated at the average exchange rates for the 
reporting period. Return on adjusted trading capital employed (ROATCE) is defined as the 
pro forma adjusted operating profit, divided by adjusted trading capital employed, where 
pro forma adjusted operating profit is the annualised adjusted operating profit including 
that of acquisitions and disposals in the period. The Directors believe that ROATCE is an 
important measure of the profitability of the Group.

Financial Statements
1.1 BASIS OF PREPARATION 
The consolidated financial statements have been prepared on a consistent basis to prior 
year and also under the historical cost convention, except for derivative financial 
instruments which are held at fair value. 
Going concern 
The consolidated financial statements have been prepared on a going concern basis. 
 The Group’s business activities, together with the factors likely to affect its future 
development, performance and position are set out in the Strategic Report on pages  
1 to 73. The financial position of the Group, its cash flows, liquidity position and borrowing 
facilities are described in the Financial Review on pages 46 to 49. In addition, pages  
150 to 154 of the Annual Report and Accounts include the Group’s objectives, policies  
and processes for managing its capital, its financial risk management objectives, details  
of its financial instruments and hedging activities, and its exposures to credit risk and 
liquidity risk. 
The Group continues to operate against a backdrop of geopolitical and macroeconomic 
uncertainties, and accordingly, the Directors have considered a comprehensive going 
concern review. The Group has considerable financial resources, together with a broad 
spread of customers and suppliers across different geographic areas and sectors, often 
secured with longer-term agreements. As a consequence, the Directors believe that the 
Group is well placed to manage its business risks successfully as described further on 
pages 54 to 60. 
Liquidity and financing position 
The Group’s liquidity and funding arrangements are described in notes 25 and 29.5 to the 
consolidated financial statements.  
Financial modelling 
The Group has modelled a base case and severe but plausible downside case in its 
assessment of going concern. The base case is driven off the Group’s detailed budget 
which is built up on a business by business case and considers both the micro and 
macroeconomic factors which could impact performance in the industries and 
geographies in which the business operates. The severe but plausible downside case 
models steep declines in revenues and operating margins resulting in materially adverse 
cash flows. These sensitivities factor in a continued unfavourable impact from a prolonged 
downturn in the economy. 
The purpose of this exercise is to consider if there is a significant risk that the Group could 
breach either its facility headroom or financial covenants. Both scenarios indicate that the 
Group has significant liquidity and covenant headroom on its borrowing facilities to 
continue in operational existence for the foreseeable future. 
Going concern basis 
Accordingly and after making inquiries, the Directors have a reasonable expectation  
that the Group has adequate resources to continue in operational existence for the 
foreseeable future and they continue to adopt the going concern basis in preparing  
the Annual Report and Accounts. 
1.2 BASIS OF CONSOLIDATION 
The consolidated financial statements incorporate the financial statements of the 
Company and entities controlled by the Company (its subsidiaries and Employee Benefit 
Trust (EBT)). Control exists when the Company is exposed or has rights to variable returns 
from its involvement with the entity and has the ability to affect those returns through its 
power over the entity. The assets, liabilities and results of subsidiaries acquired or 
disposed of during the year are included in the Consolidated Income Statement from  
the effective date of acquisition or up to the effective date of disposal, as appropriate. 
Where necessary, adjustments are made to the financial statements of subsidiaries  
to bring their accounting policies into line with those detailed herein to ensure that 
the Group financial statements are prepared on a consistent basis. All intra-Group 
transactions, balances, income and expenses are eliminated in preparing the  
consolidated financial statements. 
Non-controlling interests, defined as minority interests, in the net assets of consolidated 
subsidiaries are identified separately from the Group’s equity therein. Minority interests 
consist of the amount of those interests at the date of the original business combination 
and the minority’s share of changes in equity since the date of the combination. 
1.2.a. New accounting standards adopted 
Effective 1 October 2023, in respect of hedge accounting the Group adopted IFRS 9 
Financial Instruments, which replaces IAS 39 Financial Instruments: Recognition and 
Measurement. IFRS 9 includes requirements for the classification and measurement of 
financial instruments, impairment of financial assets and hedge accounting.

GROUP ACCOUNTING POLICIES
FOR THE YEAR ENDED 30 SEPTEMBER 2024 CONTINUED
An assessment was performed and the adoption of IFRS 9 has not had a material impact 
on the financial results of the Group. The assessment included an analysis of the Group’s 
hedge accounting policy and existing hedge accounting relationships, and it was 
determined that those relationships designated under IAS 39 are still effective under IFRS 
9. The Group has adopted the simplified approach to recognise lifetime expected credit 
losses for trade receivables and contract assets as permitted by IFRS 9. The change in 
approach has not had a material impact on the trade receivables provision. 
There have been no other new accounting standards adopted during the year that have a 
material impact over the consolidated financial statements. 
1.3 ACQUISITIONS 
Acquisitions are accounted for using the acquisition method as at the acquisition date, 
which is the date on which control is transferred to the Group. Goodwill at the acquisition 
date represents the cost of the business combination (excluding acquisition related costs, 
which are expensed as incurred) plus the amount of any non-controlling interest in the 
acquiree in excess of the fair value of the identifiable tangible and intangible assets, 
liabilities and contingent liabilities acquired. 
Minority interests may be initially measured at fair value or, alternatively, at the minority 
interest’s proportionate share of the recognised amounts of the acquiree’s identifiable  
net assets. The choice of measurement basis is made for each business  
combination separately. 
1.4 DIVESTMENTS 
The results and cash flows of major lines of businesses that have been divested are 
classified as discontinued businesses. There were no discontinued operations in either the 
current or prior year. 
1.5 REVENUE RECOGNITION 
Revenue is measured as the fair value of the consideration received or receivable for 
goods and services supplied to customers, after deducting sales allowances and value-
added taxes; revenue for services supplied to customers, as opposed to goods, is ca. 4% 
of Group revenue. Under IFRS 15, each customer contract is assessed to identify the 
performance obligation. An assessment of the timing of revenue recognition is made for 
each performance obligation. Revenue is recognised at a point in time for all standard 
revenue transactions when control of the goods provided is transferred to the customer.  
Revenue is also recognised at a point in time for contracts that contain multiple elements 
(service contracts) when the agreed output is produced by the customer, unless there are 
specific performance obligations to deliver other services over time. The revenue on such 
service contracts is not material in the context of the Group’s total revenue. 
The transaction price is allocated to each performance obligation based on the relative 
stand-alone selling prices of the goods or services provided. If a stand-alone selling price 
is not available, the Group will estimate the selling price with reference to the price that 
would be charged for the goods or services if they were sold separately. There are no 
contracts with variable consideration. 
Provision is made for returns and in the few instances where rebates are provided, though 
neither are material. There are no capitalised contract costs recognised by the Group. 
1.6 EMPLOYEE BENEFITS 
The Group operates a number of pension plans, both of the defined contribution and 
defined benefit type. 
a) Defined contribution pension plans: Contributions to the Group’s defined contribution 
schemes are recognised as an employee benefit expense when they fall due. 
b) Defined benefit pension plan: The deficit/asset recognised in the Consolidated 
Statement of Financial Position for the Group’s defined benefit pension plan is the 
present value of the defined benefit obligation at the balance sheet date less the fair 
value of the scheme assets. The defined benefit obligation/asset is calculated by 
independent actuaries using the projected unit cost method and by discounting the 
estimated future cash flows using interest rates on high-quality corporate bonds. The 
pension expense for the Group’s defined benefit plan is recognised as follows: 
i) Within the Consolidated Income Statement: 
− Service cost of current members of the Kubo Scheme. 
− Gains and losses arising on settlements and curtailments – where the item that 
gave rise to the settlement or curtailment is recognised in operating profit. 
− Any interest cost on the liabilities of the Scheme – calculated by applying the 
discount rate to the net defined benefit liability at the start of the annual  
reporting period. 
ii) Within the Consolidated Statement of Comprehensive Income (Other 
Comprehensive Income): 
− Actuarial gains and losses arising on the assets and liabilities of the plan related to 
actual experience and any changes in assumptions at the end of the year.

c) Share-based payments: Equity-settled transactions (which are where the Executive 
Directors and certain senior employees receive a part of their remuneration in the form 
of shares in the Company, or rights over shares) are measured at fair value at the date 
of grant. The fair value determined at the grant date uses the Black-Scholes method 
and takes account of the effect of market-based measures, such as Total Shareholder 
Return (TSR) targets upon which vesting of part of the award is conditional and is 
expensed to the Consolidated Income Statement on a straight-line basis over the 
vesting period, with a corresponding credit to equity. The cumulative expense 
recognised is adjusted to take account of shares forfeited by Executives who leave 
during the performance or vesting period and, in the case of non-market-related 
performance conditions, where it becomes unlikely that shares will vest. For the 
market-based measure, the Directors have used a Black-Scholes model to determine 
fair value of the shares at the date of grant. 
The Group operates an EBT for the granting of shares to Executives. The cost of shares 
in the Company purchased by the EBT are shown as a deduction from equity. 
d) Long-term employee benefits: The Group provides long-term employee benefits in the 
form of deferred remuneration to certain employees. Deferred remuneration is 
recognised as an employee benefit expense in the period in which the employee 
renders the related service. 
 
1.7 FOREIGN CURRENCIES 
The individual financial statements of each Group entity are prepared in their functional 
currency, which is the currency of the primary economic environment in which that entity 
operates. For the purpose of the consolidated financial statements, the results and 
financial position of each entity are translated into UK sterling, which is the presentational 
currency of the Group. 
a) Reporting foreign currency transactions in functional currency: Transactions in 
currencies other than the entity’s functional currency (foreign currencies) are initially 
recorded at the rates of exchange prevailing on the dates of the transactions. At each 
subsequent balance sheet date: 
i) Foreign currency monetary items are retranslated at the rates prevailing at the 
balance sheet date. Exchange differences arising on the settlement or retranslation 
of monetary items are recognised in the Consolidated Income Statement. 
ii) Non-monetary items measured at historical cost in a foreign currency are not 
retranslated. 
iii) Non-monetary items measured at fair value in a foreign currency are retranslated 
using the exchange rates at the date the fair value was determined. Where a gain or 
loss on non-monetary items is recognised directly in equity, any exchange 
component of that gain or loss is also recognised directly in equity and conversely, 
where a gain or loss on a non-monetary item is recognised in the Consolidated 
Income Statement, any exchange component of that gain or loss is also recognised 
in the Consolidated Income Statement. 
b) Translation from functional currency to presentational currency: When the functional 
currency of a Group entity is different from the Group’s presentational currency, its 
results and financial position are translated into the presentational currency as follows: 
i) Assets and liabilities are translated using exchange rates prevailing at the balance 
sheet date. 
ii) Income and expense items are translated at average exchange rates for the year, 
except where the use of such an average rate does not approximate the exchange 
rate at the date of the transaction, in which case the transaction rate is used. 
iii) All resulting exchange differences are recognised in Other Comprehensive Income; 
these cumulative exchange differences are recognised in the Consolidated Income 
Statement in the period in which the foreign operation is disposed of. 
c) Net investment in foreign operations: Exchange differences arising on a monetary item 
that forms part of a reporting entity’s net investment in a foreign operation are 
recognised in the Consolidated Income Statement in the separate financial statements 
of the reporting entity or the foreign operation as appropriate. In the consolidated 
financial statements such exchange differences are initially recognised in Other 
Comprehensive Income as a separate component of equity and subsequently 
recognised in the Consolidated Income Statement on disposal of the net investment. 
 
1.8 TAXATION 
The tax expense relates to the sum of current tax expense and deferred tax expense. 
Current tax is based on taxable profit for the year, which differs from profit before taxation 
as reported in the Consolidated Income Statement. Taxable profit excludes items of 
income and expense that are taxable (or deductible) in other years and also excludes 
items that are never taxable or deductible. The Group’s liability for current tax, including UK 
corporation tax and overseas tax, is calculated using rates that have been enacted or 
substantively enacted at the balance sheet date. 

171
DIPLOMA PLC ANNUAL REPORT 2024

Financial Statements
GROUP ACCOUNTING POLICIES
FOR THE YEAR ENDED 30 SEPTEMBER 2024 CONTINUED
Deferred tax is accounted for using the balance sheet liability method. Deferred tax is 
recognised on differences between the carrying amounts of assets and liabilities in the 
Consolidated Statement of Financial Position and the corresponding tax bases used in the 
computation of taxable profit. Deferred tax liabilities are generally recognised for all 
taxable temporary differences and deferred tax assets are recognised to the extent that it 
is probable that taxable profits will be available against which deductible temporary 
differences can be utilised. Temporary differences arise primarily from the recognition of 
the assets/liabilities on the Group’s defined benefit pension scheme, the difference 
between accelerated capital allowances and depreciation and for short-term timing 
differences where a provision held against receivables or inventory is not deductible for 
taxation purposes. However, deferred tax assets and liabilities are not recognised if the 
temporary difference arises from goodwill or from the initial recognition (other than in a 
business combination) of other assets and liabilities in a transaction that affects neither 
the taxable profit, nor the accounting profit. 
Deferred tax liabilities are also recognised for taxable temporary differences arising on 
investments in subsidiaries, except where the Group is able to control the reversal of the 
temporary difference and it is probable that the temporary difference will not reverse in 
the foreseeable future. No deferred tax is recognised on the unremitted earnings of 
overseas subsidiaries, as the Group controls the dividend policies of its subsidiaries. 
Deferred tax is calculated at the tax rates that are expected to apply to the period when 
the asset is realised or the liability is settled. Deferred tax is charged or credited to the 
Consolidated Income Statement, except when the item on which the tax or charge is 
credited or charged directly to equity, in which case the deferred tax is also dealt with in 
equity. The carrying amount of deferred tax assets is reviewed at each balance sheet date 
and reduced to the extent that it is no longer probable that sufficient taxable profits will 
be available to allow all or part of the assets to be recovered. Tax assets and liabilities are 
offset when there is a legally enforceable right to enforce current tax assets against 
current tax liabilities and when the deferred income tax relates to the same fiscal authority. 
1.9 PROPERTY, PLANT AND EQUIPMENT 
Property, plant and equipment are stated at cost less accumulated depreciation and 
accumulated impairment losses. Cost comprises the purchase price plus costs directly 
incurred in bringing the asset into use. All repairs and maintenance expenditure is charged 
to the Consolidated Income Statement in the period in which it is incurred. 
Freehold land is not depreciated. Depreciation on other items of property, plant and 
equipment begins when the asset is available for use and is charged to the Consolidated 
Income Statement on a straight-line basis to write off the cost, less residual value of the 
asset, over its estimated useful life as follows: 
Freehold property 
– between 20 and 50 years 
Leasehold improvements 
– term of the lease 
Plant and equipment 
– plant and machinery between 3 and 7 years 
– IT hardware between 3 and 5 years 
– fixtures and fittings between 5 and 15 years 
Hospital field equipment 
– 5 years 
 
The depreciation method used, residual values and estimated useful lives are reviewed 
and changed, if appropriate, at least at each financial year end. An asset’s carrying amount 
is written down immediately to its recoverable amount if the asset’s carrying amount is 
greater than its estimated recoverable amount. Gains and losses arising on disposals are 
determined by comparing sales proceeds with carrying amount and are recognised in the 
Consolidated Income Statement. 
1.10 INTANGIBLE ASSETS 
All intangible assets, excluding goodwill arising on a business combination, are stated at 
their amortised cost or fair value at initial recognition less any provision for impairment. 
Amortisation of intangible assets is recognised as an operating expense. 
a) Research and development costs 
Research expenditure is written off as incurred. Development costs are written off as 
incurred unless forecast revenues for a particular project exceed attributable forecast 
development costs in which case they are capitalised and amortised on a straight-line 
basis over the asset’s estimated useful life. Costs are capitalised as intangible assets 
unless physical assets, such as tooling, exist when they are classified as property, plant 
and equipment. 
b) Computer software costs 
Where computer software is not integral to an item of property, plant or equipment its 
costs are capitalised as other intangible assets. Amortisation is provided on a straight-line 
basis over its useful economic life of between three and seven years.

Financial Statements
GROUP ACCOUNTING POLICIES
FOR THE YEAR ENDED 30 SEPTEMBER 2024 CONTINUED
c) Acquired intangible assets – business combinations 
Intangible assets that may be acquired as a result of a business combination, include, but 
are not limited to, customer lists, supplier lists, databases, technology and software and 
patents that can be separately measured at fair value, on a reliable basis, are separately 
recognised on acquisition at the fair value, together with the associated deferred tax 
liability. Amortisation is charged on a straight-line basis to the Consolidated Income 
Statement over the expected useful economic lives. 
Fair values of customer and supplier relationships on larger acquisitions are valued using a 
discounted cash flow model; databases are valued using a replacement cost model. For 
smaller acquisitions, intangible assets are assessed using historical experience of similar 
transactions. 
d) Goodwill – business combinations 
Goodwill arising on the acquisition of a subsidiary represents the excess of the aggregate 
of the fair value of the consideration over the aggregate fair value of the identifiable 
intangible, tangible and current assets and net of the aggregate fair value of the liabilities 
(including contingent liabilities of businesses acquired at the date of acquisition). Goodwill 
is initially recognised as an asset at cost and is subsequently measured at cost less any 
accumulated impairment losses. Transaction costs are expensed and are not included in 
the cost of acquisition. 
1.11 IMPAIRMENT OF TANGIBLE AND INTANGIBLE ASSETS 
An impairment loss is recognised to the extent that the carrying amount of an asset or a 
CGU exceeds its recoverable amount. 
The recoverable amount of an asset or CGU is the higher of: (i) its fair value less costs to 
sell; and (ii) its value in use. Its value in use is the present value of the future cash flows 
expected to be derived from the asset or CGU, discounted 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. Impairment losses are recognised immediately in the Consolidated 
Income Statement. 
a) Impairment of goodwill 
Goodwill acquired in a business combination is allocated to a CGU. CGUs for this purpose 
are the Group’s three Sectors which represent the lowest level within the Group at which 
the goodwill is monitored by the Group’s Board of Directors for internal and management 
purposes. CGUs to which goodwill has been allocated are tested for impairment annually, 
or more frequently when there is an indication that the unit may be impaired. 
If the recoverable amount of the CGU is less than the carrying amount of the unit, the 
impairment loss is allocated first to reduce the goodwill attributable to the CGU. 
Impairment losses cannot be subsequently reversed. 
b) Impairment of other tangible and intangible assets 
Other tangible and intangible assets are reviewed for impairment when events or changes 
in circumstances indicate the carrying value may not be recoverable. Impairment losses 
and any subsequent reversals are recognised in the Consolidated Income Statement. 
1.12 INVENTORIES 
Inventories are stated at the lower of cost (generally calculated on a FIFO or weighted 
average cost basis depending on the nature of the inventory) and net realisable value, 
after making due allowance for any obsolete or slow moving inventory. Cost comprises 
direct materials, duty and freight-in costs. 
Net realisable value represents the estimated selling price less all estimated costs of 
completion and the estimated costs necessary to make the sale. 
1.13 FINANCIAL INSTRUMENTS 
Financial assets and liabilities are recognised in the Group’s Consolidated Statement of 
Financial Position when the Group becomes a party to the contractual provisions of the 
instrument. 
a) Trade receivables and loss allowance 
Trade receivables are initially measured at fair value, do not carry any interest and are 
reduced by a charge for impairment for estimated irrecoverable amounts. Such 
impairment losses are recognised in the Consolidated Income Statement, calculated 
under IFRS 9. 
b) Trade payables 
Trade payables are non-interest bearing and are initially measured at their nominal value. 
c) Cash and cash equivalents 
Cash and cash equivalents comprise cash in hand, interest bearing deposits, bank 
overdrafts that have a legal right of offset and short-term highly liquid investments with 
original maturities of three months or less that are readily convertible to a known amount 
of cash and are subject to an insignificant risk of changes in value. Bank overdrafts are 
repayable on demand and can form an integral part of the Group’s cash management. 

173
DIPLOMA PLC ANNUAL REPORT 2024
Strategic Report
Additional Information
Corporate Governance
Financial Statements
GROUP ACCOUNTING POLICIES
FOR THE YEAR ENDED 30 SEPTEMBER 2024 CONTINUED
Bank overdrafts (where used) are presented net of cash and cash equivalents on the 
Consolidated Statement of Financial Position, where there is a legal right of offset. 
d) Put options held by minority interests 
The purchase price of shares to be acquired under options held by minority shareholders 
in the Group’s subsidiaries are calculated by reference to the estimated profitability of the 
relevant subsidiary at the time of exercise, using a multiple based formula. The net present 
value of the estimated future payments under these put options is shown as a financial 
liability. The corresponding entry is recognised in equity as a deduction against retained 
earnings. At the end of each year, the estimate of the financial liability is reassessed and 
any change in value is recognised in the Consolidated Income Statement, as part of 
finance income or expense. Where the liability is in a foreign currency, any change in the 
value of the liability resulting from changes in exchange rates is recognised in the 
Consolidated Income Statement. 
e) Derivative financial instruments and hedge accounting 
The Group holds derivative financial instruments in the form of forward foreign exchange 
contracts to hedge its foreign currency exposure and interest rate swaps to hedge its 
exposure to market interest rates. These derivatives are designated as cash flow hedges.  
Where a derivative financial instrument is designated as a hedge of the variability in cash 
flows of a highly probable forecasted transaction, the effective part of any gain or loss on 
the derivative financial instrument is recognised in other comprehensive income and 
presented in the cash flow hedges reserve. The associated gain or loss is removed from 
equity and recognised in the Income Statement in the period in which the transaction to 
which it relates occurs. 
The Group documents, at the inception of the transaction, the relationship between 
hedging instruments and hedged items, as well as its risk management objectives and 
strategy for undertaking various hedging transactions. The Group also documents its 
assessment, both at hedge inception and on an ongoing basis, of whether the derivatives 
that are used in hedging transactions are highly effective in offsetting changes in cash 
flows of hedged items. 
The Group uses foreign currency denominated borrowings as a hedge against the 
translation exposure on the Group’s net investment in overseas companies. Where the 
hedge is fully effective at hedging, the variability in the net assets of such companies 
caused by changes in exchange rates and the changes in value of the borrowings are 
recognised in the Consolidated Statement of Comprehensive Income and accumulated in 
the Translation reserve. The ineffective part of any change in value caused by changes in 
exchange rates is recognised in the Consolidated Income Statement. 
No derivative contracts have been designated as fair value hedges. 
f) Borrowings 
Borrowings are initially recognised at the fair value of the consideration received. They are 
subsequently measured at amortised cost. Borrowings are classified as non-current when 
the repayment date is more than 12 months from the period end date or where they are 
drawn on a facility with more than 12 months to expiry. 
Borrowings include overdraft facilities that do not have a legal right of offset. 
1.14 LEASES 
The Company recognises a right-of-use asset and a lease liability at the lease 
commencement date. The right-of-use asset is initially measured at cost, being the initial 
amount of the lease liability adjusted for any lease payments made at or before 
commencement date. 
Lease liabilities are recorded at the present value of lease payments. Leases are 
discounted at the Group’s incremental borrowing rate, being the rate that the Group 
would have to pay to borrow the funds necessary to obtain an asset of similar value in a 
similar economic environment with similar terms and conditions. 
Right-of-use assets are depreciated on a straight-line basis over the lease term, or useful 
life if shorter. 
Interest is recognised on the lease liability, resulting in a higher finance cost in the earlier 
years of the lease term. 
Lease payments relating to low value assets or to short-term leases are recognised as an 
expense on a straight-line basis over the lease term. Short-term leases are those with 12 
months or less duration. 
1.15 OTHER LIABILITIES 
Other liabilities are recognised when the Group has legal or constructive obligation as a 
result of a past event and it is probable that the Group will be required to settle that 
obligation. Other liabilities are measured at the Directors’ best estimate of the expenditure 
required to settle the obligation at the balance sheet date.

1.17 SHARE CAPITAL AND RESERVES 
Ordinary shares are classified as equity and details of the Group’s share capital is 
disclosed in note (F) of the Parent Company’s financial statements. Incremental costs 
directly attributable to the issue of new shares are shown in equity as a deduction, net of 
tax, from the proceeds. The Group also maintains the following reserves: 
a) Translation reserve – The translation reserve comprises all foreign exchange differences 
arising from the translation of the financial statements of foreign businesses and net 
investment hedges. 
b) Hedging reserve – The hedging reserve comprises the effective portion of the 
cumulative net change in the fair value of cash flow hedging instruments that are 
determined to be an effective hedge. 
c) Retained earnings reserve – The retained earnings reserve comprises total cumulative 
recognised income and expense attributable to shareholders. Bonus issues of share 
capital and dividends to shareholders are also charged directly to this reserve. In 
addition, the cost of acquiring shares in the Company and the liability to provide those 
shares to employees, is accounted for in this reserve. 
Where any Group company purchases the Company’s equity share capital and holds that 
share either directly as treasury shares or indirectly within an ESOP trust, the consideration 
paid, including any directly attributable incremental costs (net of income taxes), is 
deducted from equity attributable to the Company’s equity holders until the shares are 
cancelled, reissued or disposed of. Where such shares are subsequently sold or reissued, 
any consideration received, net of any directly attributable incremental transaction costs 
and the related income tax effects, is included in equity attributable to the Company’s 
equity holders. These shares are used to satisfy share awards granted to Directors under 
the Group’s share schemes. The Trustee purchases the Company’s shares on the open 
market using loans made by the Company or a subsidiary of the Company. 
1.18 RELATED PARTIES 
There are no related party transactions (other than with key management) that are required 
to be disclosed in accordance with IAS 24. Details of their remuneration are given in note 5 
to the consolidated financial statements. 
1.19 ASSETS AND LIABILITIES CLASSIFIED AS HELD FOR SALE 
Non-current assets held for sale and disposal groups are presented separately in the 
current section of the Consolidated Statement of Financial Position when the following 
criteria are met: the Group is committed to selling the asset or disposal group, it is 
available for immediate sale in its current condition, an active plan of sale has 
commenced, and in the judgement of Group Management it is highly probable that the 
sale will be completed within 12 months. Immediately before the initial classification of the 
assets and disposal groups as held for sale, the carrying amounts of the assets (or all the 
assets and liabilities in the disposal groups) are measured in accordance with the 
applicable accounting policy. Assets held for sale and disposal groups are subsequently 
measured at the lower of their carrying amount and fair value less costs of disposal. Assets 
held for sale are no longer amortised or depreciated. 
1.20 ACCOUNTING STANDARDS, INTERPRETATIONS AND AMENDMENTS  
TO PUBLISHED STANDARDS NOT YET EFFECTIVE 
The IASB has published a number of new IFRS standards, amendments and interpretations 
to existing standards which are not yet effective, but will be mandatory for the Group’s 
accounting periods beginning on or after 1 October 2024.

covenants and deferral of effective date, and the Disclosure of Accounting Policies;

Financial Statements
The Group does not anticipate that the adoption of these standards and interpretations 
that are effective for the year ending September 2025 will have a material effect on its 
financial statements. 
1.21 SIGNIFICANT ACCOUNTING ESTIMATES AND CRITICAL JUDGEMENTS 
The preparation of the Group’s consolidated financial statements requires management to 
make critical accounting judgements, assumptions or estimates with regard to assets or 
liabilities that could potentially have a material adjustment to the carrying amount of 
assets or liabilities in the next 12 months. 
1.21.1 Acquisition accounting (estimate) 
Acquisition accounting is a significant accounting estimate. 
When the Group makes an acquisition it recognises the identifiable assets and liabilities, 
including intangible assets, at fair value with the difference between the fair value of net 
assets acquired and the fair value of consideration paid comprising goodwill. Acquisitions 
are accounted for using the acquisition method as described in the Group Accounting 
Policies. The key assumptions and estimates used to determine the valuation of intangible 
assets acquired are the forecast cash flows, the discount rate and customer/supplier 
attrition. Customer and supplier relationships are valued using an excess earnings cash 
flow model. Acquisitions often comprise an element of deferred consideration and may 
include a minority interest, which are subject to put options. These put options are valued 
at fair value at the date of acquisition. Deferred consideration is fair valued based on the 
Directors’ estimate of future performance of the acquired entity. 
The significant assumptions in valuing the PAR Group and Peerless intangible assets, which 
were acquired in the year, together with the sensitivity analysis, are set out below. 
PAR Group 
Peerless 
Discount rate + 1% (all intangibles) 
ca. £(0.5)m 
ca. £(1.8)m 
Discount rate - 1% (all intangibles) 
ca. £0.6m 
ca. £1.9m 
Revenue growth rate +1% (all intangibles) 
ca. £1.3m 
ca. £1.8m 
Revenue growth rate –1% (all intangibles) 
ca. £(1.2)m 
ca. £(1.7)m 
Customer attrition rate +1% (customer relationships) 
ca. £(0.5)m 
ca. £(2.1)m 
Customer attrition rate –1% (customer relationships) 
ca. £0.6m 
ca. £2.2m 
 
Management is also required to make judgements, assumptions and estimates relating to 
certain assets and liabilities that could potentially have a material impact over the longer 
term. These relate to: 
1.21.2 Goodwill impairment (estimate) 
The Group has material amounts of goodwill and intangible assets (principally customer 
and supplier relationships) recognised in the Consolidated Statement of Financial Position. 
As set out in note 1.11 of the Group Accounting Policies, goodwill is tested annually to 
determine if there is any indication of impairment. Assumptions are used to determine the 
recoverable amount of each CGU, principally based on the present value of estimated 
future cash flows to derive the ‘value in use’ to the Group of the capitalised goodwill. The 
key estimates made and assumptions used in performing impairment testing this year are 
set out in note 10 to the consolidated financial statements. 
1.21.3 Inventory provisions (estimate) 
Inventories are stated at the lower of cost and net realisable value as set out in note 1.12 of 
the Group Accounting Policies. In the course of normal trading activities, estimates are 
used to establish the net realisable value of inventory and impairment charges are made 
for obsolete or slow-moving inventories and against excess inventories. 
The decision to make an impairment charge is based on a number of factors including 
management’s assessment of the current trading environment, aged profiles and historical 
usage and other matters which are relevant at the time the consolidated financial 
statements are approved. 
1.21.4 Defined benefit pension (estimate) 
Defined benefit pensions are accounted for as set out in note 1.6 of the Group Accounting 
Policies. Determining the value of the future defined benefit obligation requires estimates 
in respect of the assumptions used to calculate present values. These include discount 
rate, future mortality and inflation rate. Management makes these estimates in 
consultation with an independent actuary. For the year ended 30 September 2024, all 
members of the UK defined benefit pension scheme are covered by one of the Scheme’s 
Buy-In policies. Therefore, with the exception of liabilities in respect of GMP equalisation, 
the liabilities due are exactly matched by the policies held. The Kubo defined benefit 
pension scheme is a net liability. Detail of the estimates and key sensitivities made in 
calculating the defined benefit assets and obligations at 30 September 2024 are set out 
in note 26 to the consolidated financial statements.

Measure
Closest 
UK-adopted 
IAS measure
Definition and reconciliation
Purpose
Organic 
growth
Reported 
revenue 
increase 
Organic growth strips out 
the effects of the movement 
in exchange rates and of 
acquisitions and disposals.
Allows users of the accounts to 
gain understanding of how the 
Group has performed on a 
like-for-like basis, excluding 
the effects of exchange rates 
and of acquisitions and 
disposals. 
Adjusted 
operating 
profit
Operating 
profit
Statutory operating profit 
excluding separately disclosed 
items and can be found on 
the face of the Group Income 
Statement in the Adjusted 
column.
Adjusted operating profit is 
a key performance measure 
for the Executive Directors’ 
annual bonus structure and 
management remuneration.
It also provides all stakeholders 
with additional useful 
information to assess the 
period-on-period  trading 
performance of the Group.
Adjusted 
operating 
margin 
Operating 
profit divided 
by revenue
Adjusted operating profit/(loss) 
divided by revenue.
Adjusted operating margin is 
a measure used to assess and 
compare profitability.
It also allows for ongoing 
trends and performance of the 
Group to be measured by the 
Directors, management and 
interested stakeholders.
Measure
Closest 
UK-adopted 
IAS measure
Definition and reconciliation
Purpose
Adjusted 
earnings per 
share
Basic earnings 
per share
Adjusted earnings (being 
adjusted profit after tax 
attributable to equity 
shareholders) for the period 
attributable to shareholders 
of the Group divided by the 
weighted average number of 
shares in issue, excluding those 
held in the Employee benefit 
trust which are treated as 
cancelled. 
A reconciliation of statutory 
profit to adjusted profit for the 
purpose of this calculation is 
provided within the notes to 
the financial statements. 
Adjusted earnings per share 
is widely used by external 
stakeholders, particularly in 
the investment community.
Return on 
adjusted 
trading 
capital 
employed 
(ROATCE)
Operating 
profit divided 
by net assets
Pro forma adjusted operating 
profit (being the annualised 
adjusted operating profit 
including that of acquisitions 
and disposals) divided by 
adjusted trading capital 
employed. Adjusted trading 
capital employed is reported 
as being trading capital 
employed plus goodwill and 
acquisition related charges 
previously written off (net of 
deferred tax on acquisition 
intangible assets) and re-
translated at the average 
exchange rates that are 
consistent with the proforma 
adjusted operating profit.
ROATCE gives an indication of 
the Group’s capital efficiency 
and is an element of a 
performance measure 
for the Executive Directors’ 
remuneration.

Measure
Closest 
UK-adopted 
IAS measure
Definition and reconciliation
Purpose
Free cash 
flow
Net cash 
generated 
from operating 
activities
The cash flow equivalent 
of adjusted profit after tax.
Free cash flow allows us and 
external parties to evaluate the 
cash generated by the Group’s 
operations and is also a key 
performance measure for the 
Executive Directors‘ annual 
bonus structure and 
management remuneration.
Net debt
Borrowings 
less cash 
Cash and cash equivalents 
(cash overnight deposits, other 
short-term deposits) offset by 
borrowings which compose of 
bank loans, excluding lease 
liabilities.
Net debt is the measure by 
which the Group and interested 
stakeholders assesses its level 
of overall indebtedness.
Earnings 
Before 
Interest and 
Tax plus 
Depreciation 
and 
Amortisation 
(EBITDA)
Operating 
profit
EBITDA is calculated by taking 
adjusted operating profit, 
adding back depreciation and 
amortisation and annualised for 
acquisitions and disposals 
made during the year.
EBITDA is used as a key 
measure to understand profit 
and cash generation before 
the impact of investments 
(such as capital expenditure 
and working capital). It is also 
used to derive the Group’s 
gearing ratio.
Measure
Closest 
UK-adopted 
IAS measure
Definition and reconciliation
Purpose
Leverage
No direct 
equivalent
The ratio of net debt to EBITDA 
over the last 12 months (with 
net debt translated at the 
average exchange rates that 
are consistent with EBITDA), 
after making the following 
adjustments to EBITDA: 
including any annualised EBITDA 
for businesses acquired by the 
Group during that financial 
year; the reversal of IFRS 16 
accounting; the exclusion 
of any EBITDA of businesses 
disposed by the Group during 
that financial year; and the 
exclusion of the profit or loss 
attributable to minority interest.
The leverage ratio is considered 
a key measure of balance sheet 
strength and financial stability 
by which the Group and 
interested stakeholders 
assesses its financial position.
