VALUES

DAVID LOWDEN
CHAIR

DIPLOMA PLC  ANNUAL REPORT 2023  −  3 

“ Our success is underpinned by the 
characteristics of our decentralised 
model, which embodies entrepreneurship, 
autonomy and leadership.”

COLLEAGUES AND CULTURE 
Our colleagues are the foundation  
of the Group’s success and they  
are central to our identity. Our  
culture and values play a pivotal  
role in supporting our colleagues' 
engagement, growth, and  
fulfilment as valued members 
of the Diploma family. 

We are guided by five core values 
that shape our every decision and 
action. 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, 
as it is in unity that we reach new 
heights. And finally, we are down 
to earth, maintaining a culture 
of humility and approachability. 

It is through these values and the 
dedication of our colleagues that 
we continue to deliver excellence 
in all that we do. Our colleagues 
have been an integral part of our 
ongoing success.

We are also seeing growth in 
a number of areas aligned with 
positive impact, demonstrating 
that our businesses are embedding 
Delivering Value Responsibly (DVR), 
our ESG programme, into their 
commercial strategies. It has been 
another busy year for acquisitions, 
with 12 high-quality businesses 
joining the Group; these will 
accelerate our future organic 
growth. In particular, I am very 
pleased to warmly welcome our 
colleagues at DICSA, T.I.E. and 
all other businesses joining the 
Group during the year. 

Given the challenges of the external 
operating environment, improving 
our adjusted operating margin by 
80bps to 19.7% (2022: 18.9%) is a 
great achievement and reflects 
both our differentiated value-add 
servicing model and the hard work 
of colleagues across the Group. 

Ensuring the sustainability of our 
growth is paramount, and the team 
has continued to build scale by 
investing across our businesses and 
the Group to ensure we can continue 
to deliver for customers as we grow. 
Throughout this, we remain financially 
disciplined, maintaining high-teens 
ROATCE of 18.1%, and a strong 
balance sheet, which allows us 
to invest in growth. I would like 
to thank the Executive Team and 
all of our businesses for another 
great year at Diploma. 

I am delighted to present the 
Chair’s statement for 2023. This 
year has been an exceptional year 
for our Group, both strategically 
and operationally, as you will 
read in this report. Our success is 
underpinned by the characteristics 
of our decentralised business model 
which embodies entrepreneurship, 
autonomy and exceptional 
leadership, allowing us to remain 
resilient and maintain strong financial 
success in challenging environments. 

VERY STRONG FINANCIAL 
PERFORMANCE AND EXCELLENT 
STRATEGIC PROGRESS 
The Group has delivered another 
very strong financial performance, 
with 8% organic revenue growth and 
consistent strong operating margins 
translating to 18% growth in adjusted 
earnings per share (EPS). Our strong 
organic growth shows that our 
strategy and growth frameworks 
continue to produce results and 
remain resilient.

CHAIR’S STATEMENT CONTINUED

We are committed to developing 
our colleagues and fostering 
growth. Over the past year, we have 
made a concerted effort to offer 
apprenticeships to individuals who 
are eager to learn and gain practical 
experience. These initiatives not only 
allow us to discover fresh talent but 
also provide a valuable learning 
experience for new colleagues.

Our Group Colleague Engagement 
Survey continues to indicate 
excellent levels of engagement.  
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 to 
support the wellbeing and success 
of our colleagues.

BOARD CHANGES 
After nearly nine years of service, 
Anne Thorburn will be stepping down 
from the Board and the positions 
of Chair of the Audit Committee 
and Senior Independent Director 
during 2024. The Nomination 
Committee has begun a search 
process and an announcement 
will be made at the appropriate 
time regarding Anne's successor.

We welcomed Jennifer Ward 
to the Board on 1 June 2023  
as Non-Executive Director  
and Chair-Designate of the  
Remuneration Committee. Andy 
Smith will step down from the  
Board and its Committees in a few 
months, following nearly nine years 
of service, to facilitate a smooth 
handover of the Remuneration 
Committee Chair. 

I would like to take this opportunity 
to also thank both Anne and Andy 
on behalf of the Board for their 
outstanding contribution and 
dedication throughout their 
service to the Group.

We recognise that diverse 
perspectives and experiences drive 
innovation, decision-making, and 
long-term sustainability. We are 
therefore mindful of the diversity 
and inclusion targets set by the 
FCA’s listing rules for gender 
and ethnic diversity on the Board, 
as well as senior management 
teams. These targets are factored 
into our succession planning 
processes to ensure that we 
are inclusive, representative and 
equipped to thrive as our business 
grows. Further information on 
the composition and diversity 
of the Board, as well as senior 
management, can be found in the 
Nomination Committee Report.

DIVIDENDS
The Board has a progressive 
dividend policy that aims to  
increase the dividends per share 
each year, by 5%. 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 40.0p (2022: 38.8p) 
taking the total dividend to 56.5p 
(2022: 53.8p). Subject to shareholder 
approval at the Annual General 
Meeting, this dividend will be paid 
on 2 February 2024 to shareholders 
on the register at 19 January 2024 
(ex-div 18 January 2024).

“ Our colleagues are the 
foundation of the Group’s 
success and they are 
central to our identity.”

OUTLOOK
In conclusion, it has been a 
remarkable year for our Group. 
Not only have we achieved 
significant financial success, we have 
also evolved 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 
position 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 and transformation.

DEVELOPING 
  A DIPLOMA 
CULTURE  
  AND IDENTITY

Our ongoing success is driven by 
brilliant, effective leadership and 
strong colleague engagement. 

Both of these are supported by 
our culture. As a Group, Diploma 
has a strong purpose, values and 
common cultural fundamentals 
that govern our actions and 
provide guidance across 
our businesses. 

Our culture is a commercial and 
strategic advantage and reflects 
our decentralised model. It 
empowers our businesses to 
deliver the right solutions for 
their customers, in their own way. 

All businesses feel a sense of 
belonging and allegiance to the 
Group thanks to our shared values, 
brilliant leadership teams, and 
intercompany networks and 
best practice sharing. 

As part of Diploma, our businesses 
can leverage the additional 
resources, opportunities and 
expertise of a large, international 
and diversified Group to benefit 
their customers, colleagues, 
suppliers and communities.

HOW WE DO IT

Our decentralised model empowers 
our businesses to work alongside their 
customers to deliver practical and 
innovative solutions that keep key 
industries moving. By focusing on 
value-add solutions, not just products, we 
are an essential partner to our customers.

VALUE-ADD SERVICE 
DISTRIBUTION MODEL
We’re a service business  
as much as we are a 
distribution business.  
Our products all come 
with a value-add wrapper 
– whether that’s technical 
expertise, responsive 
customer service, or 
product customisation 
– we create solutions that 
make our customers’ lives 
easier. Our products and 
services are critical to our 
customers’ value chain 
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.

VALUE-ADD ON  
OUR WEBSITE

ABOUT-US/

BRILLIANT PEOPLE AND 
DECENTRALISED CULTURE
We believe in 
accountability at the 
front of the organisation. 
Our businesses are 
empowered to deliver 
for their customers, their 
way. As part of Diploma, 
our businesses can also 
leverage the resources, 
opportunities and 
expertise of a large, 
international and 
diversified Group to 
benefit their customers, 
colleagues, suppliers 
and communities. 
Our colleagues have 
the technical expertise, 
specialist knowledge 
and market experience 
to fulfil our purpose.

Our strong leadership 
teams keep our shared 
culture and values alive 
across the Group.

“ What sets VSP aside is the innovation behind 
the engineering and the research that goes into that. 
They are extremely responsive if you need something, 
they are very quick to put you in touch with the right 
engineer to solve a problem. That could be a small 
problem or a larger, more catastrophic issue. Knowing 
that the end product is going to be the right product 
applied in the right way, that's priceless.”

STRATEGY

BUILDING HIGH-QUALITY 
SCALABLE BUSINESSES 
FOR SUSTAINABLE  
ORGANIC GROWTH

Our strategy is delivered by a brilliant team 
in an empowered decentralised culture. 
As a result, we have an impressive and resilient 
track record of growth at attractive margins.

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.  

We complement our organic growth 
strategy with bolt-on acquisitions 
that drive future organic growth in 
one or more of our three buckets.

Our value-add model and 
decentralised culture are our key 
differentiators. As we grow, we need 
to build scale within the businesses 
and the Group in order to protect 
our differentiators and sustain 
long-term delivery.

Our Delivering Value Responsibly 
(DVR) framework means that we are 
positioned to deliver products and 
services for a decarbonising 
economy, whilst also delivering for 
our colleagues and the environment.

We have an exciting opportunity 
to access structurally high-growth 
end markets, such as clinical 
diagnostics, electrification, 
industrial automation, 
infrastructure, renewables, 
water management, energy, 
and civil aerospace. We have 
increased our exposure in these 
markets, but still have a very 
small share. We also have the 
opportunity to position ourselves 
for a more sustainable economy.

We remain focused on our core, 
developed economies of North 
America, UK & Ireland, Continental 
Europe, and Australia & New 
Zealand. We have minimal market 
share – or none at all – in most of 
our product verticals across our 
core geographies and therefore 
do not need to look to higher-risk, 
developing markets for growth. 
There is lots to go for in our 
established geographies.

We expand our addressable 
markets through product 
extension. We do this through 
continuous product innovation; 
coordinated cross-selling across 
different Group businesses; or, 
selectively, through building out 
material new product lines that 
support value-add distribution.

STRATEGY CONTINUED

ORGANIC  
  GROWTH AT 
AUSTRALIAN SEALS 

Our Australian Seals business 
supplies premium mechanical 
engineering products, parts 
and services to the power, 
water and mining industries.

Since 2019, their organic 
growth has been consistently 
double-digit. Since 
joining Diploma, it has 
made some strategic 
acquisitions to accelerate 
organic growth through 
geographic penetration 
and product extension. 

The bolt-on acquisition ACT in 
2022 introduced exciting and 
innovative products, creating 
an attractive, full-service 
proposition for customers. 

The dewatering unit in 
Australian Seals has also 
grown by more than 50% 
since 2019. By increasing 
its product offering and 
expanding service it 
has improved sales mix. 
Operating margin has 
improved from low  
double-digits to high-teens 
during the same period.

The business has also been 
able to take advantage of 
exciting opportunities in the 
waste management, water 
and marine industries, as 
well as expanding its repair 
service, driven by new 
refineries, including Lithium.

Spanish-based investment. Both 
companies have a long track record 
of excellent organic growth and 
high margins.

COMPLEMENTARY  
ACQUISITIONS TO DRIVE  
FUTURE ORGANIC GROWTH 
We make complementary 
acquisitions to drive future organic 
growth, positioning behind exciting 
end markets, expanding our footprint 
in a core geography, or adding 
product capability. Acquisitions also 
help us to build scale and resilience, 
bring in fantastic new talent, and 
drive great returns on capital. 

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. 

We are long-term investors in our 
businesses and help acquired 
businesses develop and grow. 
We do this by offering management 
expertise, assisting with a more 
structured sales approach, sharing 
best practice across similar Group 
companies, improving margins and 
cash management, and providing 
an ESG framework. 

As a result, we have a strong track 
record of delivering disciplined 
acquisitions with great returns. 
Since 2019 we have spent over 
£1 billion on acquisitions that have 
delivered average organic growth 
and ROATCE of ca. 16%.

A WINNING PROPOSITION  
FOR SELLERS
Our decentralised model and culture 
make us attractive to small business 
owners. We preserve their legacy, 
value and develop their people, 
and we’re in it for the long term. 
This gives us a competitive 
advantage where price is not 
the sole decision driver. 

EXCITING PIPELINE
We have a strong internal corporate 
development team, and have 
developed our capabilities and 
processes over the past couple 
of years. This, together with our 
winning proposition for sellers, 
large fragmented markets 
and white space, leads to an 
exciting pipeline of continued 
acquisition opportunities.

STRATEGY CONTINUED

SCALE

Our differentiators are our value-add 
business model and decentralised 
culture. As the businesses – and the 
Group – become significantly larger, 
we have to scale at the same time in 
order to preserve and enhance those 
differentiators and guarantee our 
delivery for the long term.

VALUE-ADD BUSINESS  
MODEL AT SCALE 
To scale successfully, each of our 
businesses designs their operating 
model of the future, the processes 
and core competencies that 
underpin it, and the capability 
– talent, technology, and facility 
– required to deliver it.

Our core competencies are 
common to all our businesses: 
value-add, route to market, 
operational excellence, supply chain 
management, commercial discipline. 

Strengthening them requires the 
business to be more strategic, 
structured and systematic, which 
in turn improves customer service 
and performance.

POWERFUL DECENTRALISED  
GROUP AT SCALE 
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.

Lean structures with dynamic leaders. 
By remaining lean, we ensure agility 
and execution while avoiding 
unnecessary bureaucracy. 
This approach requires great 
management, and so we have 
development and engagement 
programmes to ensure this. 

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. 

All of this means that 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.

BUILDING SCALE AT  
   WINDY CITY WIRE 

Windy City Wire, part of the 
Controls Sector, has cultivated a 
very high-performance culture 
with strong sales expertise. 
Every colleague is clear on their 
objectives and job role, ensuring 
clarity and simplicity in a rapidly 
growing business. 

Windy City Wire uses 
technology to improve 
efficiency. All of their 
performance metrics are

CEO’S REVIEW

SUSTAINABLE 
  QUALITY 
  COMPOUNDING

JOHNNY THOMSON
CHIEF EXECUTIVE OFFICER

Revenue in the year was 
up 19% to: 

£1.2bn

 DIPLOMA PLC  ANNUAL REPORT 2023  −  19 

Our adjusted operating  
profit increased by  
24% to £237.0m

“ I am extremely pleased with our financial 
performance and strategic progress.  
I would like to thank my brilliant 
colleagues across the Group who 
do a fantastic job every single day.”

EXCELLENT FINANCIAL 
PERFORMANCE, DELIVERED 
WITH DISCIPLINE
The Group has delivered another 
successful year, reflecting the power 
of our value-add propositions, our 
strategy, and our decentralised 
model. This, underpinned by the 
commitment of our colleagues to 
deliver excellent customer service, 
has enabled us again to deliver 
strong organic growth at high 
and growing margins. 

Revenue in the year was up 19% 
to £1.2bn (2022: £1.0bn). Organic 
growth of 8% was driven by strong 
volumes. Acquisitions, net of a small 
disposal, contributed 8% to reported 
revenue while foreign exchange 
translation added a further 3%. 

Our value-add customer 
propositions enable us to price 
to offset cost inflation and then 
selectively reinvest some of the 
benefits of positive operational 
leverage into scaling our businesses. 
This 'margin formula', coupled 
with disciplined cost control 
and accretive acquisitions, means 
that we have increased adjusted 
operating margin by 80 bps to a 
very strong 19.7% (2022: 18.9%). Our 
adjusted operating profit increased 
by 24% to £237.0m (2022: £191.2m). 

Adjusted earnings per share (EPS) 
grew by 18%, continuing our long-
term compounding track record 
(15% compound annual growth rate 
(CAGR) EPS over 15 years).

Our cash-generative business model 
drove free cash flow conversion 
of 100% (2022: 90%), benefitting 
from targeted inventory reduction. 
Together with the equity raise earlier 
in the year, this led to a reduction 
in net debt to £254.7m, reducing 
leverage to 0.9x at 30 September 
2023 (2022: £328.9m and 1.4x). 
Returns on capital are a key underpin 
of our compounding financial model 
and return on average trading capital 
employed (ROATCE) improved by 80 
bps to 18.1% (2022: 17.3%).

REVENUE DIVERSIFICATION 
DRIVING ORGANIC GROWTH 
AND INCREASING RESILIENCE
The Group’s strategy is to build 
high-quality, scalable businesses 
for organic growth. 

We drive organic growth in three 
ways: positioning behind 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 8% in FY23, with strong trading 
momentum as we exit the year.

growth are set out below, with further 
detail provided in the Sector Reviews 
on pages 24 to 35.

Positioning to take advantage of 
structurally growing end markets 
Across the Group we have continued 
to drive growth through expansion 
in structurally growing end markets.  
A number of businesses in our 
Controls Sector are gaining share 
in aerospace, defence and energy 
markets as well as penetrating the 
wider electrification ecosystem. 
The acquisition of Tennessee 
Industrial Electronics (T.I.E.), in March 
gives us access to the strategically 
important industrial automation end 
market in the US. Across our Seals 
businesses, we are well positioned to 
benefit from US infrastructure spend 
and we have diversified into exciting 
growing markets such as water 
treatment and renewable energy. 
In Life Sciences, in addition to 
benefitting from the recovery of 
surgical procedures, our businesses 
are continuing to diversify, in 
particular across diagnostic areas 
such as molecular testing, allergy and 
auto-immune testing, haematology, 
and cancer screening.

Penetration of core 
developed economies
Over the last year we have made 
progress developing our US and 
European footprint. In Controls, 
for example, we continue to win 
market share in the German energy 
market delivering very strong 
double-digit growth. 

In Seals, we are continuing to win 
share in the western and mid-west 
states of the US, leveraging the 
investment in the facility in Louisville. 
In the UK, R&G has enjoyed a very 
strong first year in the Group, building 
out our regional position and product 
offerings to drive excellent organic 
growth. The acquisition of 
Distribuidora Internacional Carmen  
S.A.U. (DICSA) in July creates a 
platform for our fluid power business 
in Spain and across Europe, including 
cross-selling opportunities with R&G. 
In Life Sciences, we now have a 
scaled European platform. 

Product range extension 
New product development forms 
an ongoing component of all our 
businesses’ organic growth strategies.

•  Controls has delivered outstanding 
growth from speciality adhesives, 
having entered that segment 
through the acquisition of Techsil 
in 2021. The acquisition of T.I.E. 
brings expertise in aftermarket 
and circular economy solutions 
for CNC machines and robotics.

•  With the acquisition of DICSA, 

following last year’s acquisition of 
R&G, Seals continues to diversify 
from its traditional strength across 
seals and gaskets, into wider fluid 
power products.

•  Product development is intrinsic 
to our Life Sciences businesses. 
The Canadian businesses 
introduced new technology in 
the gastrointestinal and surgical 
segments. The European 
businesses introduced the  
single-use endoscope in the 
Urology segment, as well as 
new ultrasound technology, 
and new products in the 
lab and pharmaceutical 
testing environments. 

DIPLOMA PLC  ANNUAL REPORT 2023  −  21 

Since 30 September 2022,  
we have acquired 12 high  
quality businesses for  
a total of £280m 

£280m

COMPLEMENTARY ACQUISITIONS 
TO ACCELERATE GROWTH 
Acquisitions can accelerate our 
growth strategy. We are disciplined 
and selective and will only consider 
opportunities with the following core 
characteristics:

•  differentiated value-add customer 
proposition generating sustainable 
high gross margins;

•  strong organic growth and scaling 

potential; and

•  capable management teams 

we can back.

Since 30 September 2022, we have 
acquired 12 high-quality businesses 
for a total of £280m.

In March, we acquired T.I.E. for  
ca. £76m, entering the strategically 
important industrial automation end 
market in the US. T.I.E. is a high 
growth, market-leading value-add 
distributor of aftermarket parts and 
repair services for robotics and CNC 
machines. It differentiates through 
speed to market and superior 
technical support, driving a strong 
organic growth track record and 
high margins.

In July, we acquired DICSA for ca. 
£170m, establishing a platform in 
fluid power solutions across the 
European aftermarket. DICSA has 
significant customer value-add, 
based on quality product, breadth of 
range, technical service, and speed 
to market. It adds to our established 
positions in the US and UK, 
expanding our aftermarket fluid 
power capability and accessing 
key strategic markets. 

Over time we will drive significant 
revenue and procurement synergies 
including cross-selling existing 
product from R&G through DICSA’s 
platform into Europe; leveraging our 
North American Seals Aftermarket 
platform to accelerate DICSA’s 
growth in the US; and delivering 
consolidated procurement synergies.

Both T.I.E. and DICSA are strategic 
platform acquisitions, well positioned 
for continued strong growth, and are 
margin and earnings accretive in the 
first year.

During the year, we have also 
completed 10 bolt-on acquisitions for 
£33m, at an average earnings before 
interest and tax (EBIT) multiple of 
under 5x. These will add £33m of 
annual revenue to the Group at 
accretive EBIT margins, driving 
ROATCE of over 20% from their 
first full year.

Continuing our disciplined approach 
to portfolio management, we 
disposed of the lower growth, 
lower margin Hawco business (fluid 
controls within the Controls Sector) 
in March for £23m.

In fragmented markets with a 
well-developed approach and a 
compelling proposition to sellers, 
the Group’s acquisition pipeline is 
strong and diversified. We remain 
committed to disciplined investment 
of capital, ensuring the Group’s 
acquisitions support our future 
organic growth and deliver 
compounding earnings growth 
at high returns over the long term.

building high-quality 
businesses for sustainable 
organic growth requires 
that we scale the 
businesses, developing 
their operating models to 
continue to deliver great 
customer propositions 
at scale.”

22  −  DIPLOMA PLC  ANNUAL REPORT 2023

CEO’S REVIEW CONTINUED

SCALING THE BUSINESSES 
AND THE GROUP
Delivering our strategy of 
building high-quality businesses for 
sustainable organic growth requires 
that we scale the businesses, 
developing their operating models 
to continue to deliver great customer 
propositions at scale. At the same 
time, we are developing the Group, 
evolving our structures, capabilities 
and culture to support this growth 
and maintain discipline and 
appropriate controls.

Scaling the Businesses 
We have a simple, common 
framework which enables our 
businesses to deliver their target 
operating models. We have a set 
of core competencies (value-add, 
supply chain, operational excellence, 
commercial discipline, and route to 
market) which underpin their model. 

As well as developing core 
competencies, scaling our businesses 
requires selective investment in 
capability, in the form of talent, 
technology, and facilities. During the 
year, we have invested in functional 
leadership across a number of our 
businesses, creating or upgrading 
roles in areas such as supply chain 
management, operations, route to 
market and support functions. From 
a technology perspective, we have 
Enterprise Resource Planning (ERP) 
upgrade projects underway across 
a number of businesses, as well 
as automated warehouse system 
upgrades in some Seals and Controls 
businesses. In terms of facilities, 
we have upgrades and relocations 
underway in each of our three Sectors 
to drive efficiency and improved 
customer service as those businesses 
continue to grow.

Scaling the Group
We have continued to focus on 
three principles this year:

First: keep it focused. This means 
portfolio discipline to ensure a 
manageable platform for scale. 
Despite more than doubling in 
size, we have moved from 20 to 16 
business units in the last four years. 
For example, during the year we 
created new scaled businesses in 
Life Sciences (Canada and Ireland) 
and Seals (Australia) by combining 
smaller constituent businesses to 
form integrated operations that are 
better able to service their 
customers at scale.

Second: lean structures with dynamic 
leaders. This avoids bureaucracy 
in the businesses and promotes 
alignment, agility and execution. 
We have very lean Central and Sector 
teams but require more capability and 
capacity as we grow. During the year 
we have selectively added capability 
in Finance, HR, Sustainability and 
Risk & Compliance roles. Through 
our development processes and 
programmes, alongside external 
appointments, we are building 
talent and succession across the 
organisation.

Third: mood - the beat of the 
organisation. Decentralisation doesn’t 
mean isolation. Regular individual and 
collective touchpoints allow us to be 
agile, manage pace, and execute 
better. This year, we have further 
developed the ‘Diploma Identity’, 
strengthening leadership networks, 
collaboration and best practice 
sharing, while preserving our critical 
differentiated decentralised culture. 

DIPLOMA PLC  ANNUAL REPORT 2023  −  23 

At this stage in the year, FY24 growth 
is expected to be in line with our 
long-term financial model, albeit 
at higher margins: 

•  Volume-led organic revenue 

growth of ca. 5%.

•  Acquisitions announced to date 
add ca. 6% (net) to reported 
revenue growth.

•  Strong operating margin 

of ca. 19.7%.

•  Free cash flow conversion 

of ca. 90%.

We remain focused on executing our 
strategy of building high-quality, 
scalable businesses for organic 
growth and are confident in our 
ability to deliver long-term growth 
at sustainably high margins.

Johnny Thomson
Chief Executive Officer

DELIVERING VALUE RESPONSIBLY
We are making good progress across 
our businesses with Delivering Value 
Responsibly (DVR). During the year 
we have hired an experienced Group 
Sustainability Director and submitted 
our net zero targets for validation 
to the Science Based Targets 
initiative (SBTi).

DVR, our framework, is focused 
on six core areas:

•  Colleague Engagement increased 

to 80%, a very strong result 
particularly for a decentralised 
business. We have engagement 
plans in each of our businesses and 
aim to maintain engagement above 
70% over the long-term.

•  Workshops and listening groups 
are also helping to further our 
Diversity, Equity & Inclusion 
agenda. Over the last four years 
our gender diversity has improved, 
with women now representing 28% 
of our Senior Management Team 
(SMT) up from 20% in 2019. Our 
2030 target is for women to make 
up 40% of our SMT. 

•  Potential hazard reporting and 

training are enhancing our Health 
& Safety culture. In 2023, our lost 
time incident (LTI) Rate (LTIs per 
1,000 employees) was 9.5 (2022: 
10.6). We target at least a 5% 
reduction in lost time incidents 
every year. 

•  Our businesses are stepping up 
engagement with their Supply 
Chains. Over 70% of key suppliers 
are now aligned to our Supplier 
Code - committing to high ethical, 
professional and legal standards. 

•  Further focus on the Climate 
Action has included energy 
workshops and implementing 
emission-reduction initiatives.  
We have begun to introduce 
solar solutions on our facilities 
and expect to progress this 
further in the coming year. 
Our target is to achieve net zero 
across our value chain by 2045, 
with a 50% reduction in Scope 1 
& 2 emissions by 2030.

•  We are making good progress in 

Waste Reduction, with the volume 
of waste sent to landfill down to 
32% from 60% in the prior year. 

We are also focused on the positive 
impact that our Group has on society 
and the environment by delivering 
innovative and life-saving healthcare 
solutions; playing a role in renewable 
energy generation; and supporting 
circular practices across our 
aftermarket businesses. 

OUTLOOK
Whilst we remain mindful of the 
uncertain economic outlook, we are 
confident in the Group’s prospects. 
Diploma has an excellent track 
record of compounding growth and 
delivering strong financial returns 
through the cycle. Our model is 
resilient, and its resilience has 
increased over time as we execute 
our strategy:

•  Our revenue is resilient: ongoing 
diversification means we are 
exposed to structurally growing 
end segments.

•  Our margins are resilient: focus on 

value-add solutions 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.

contributed to margin expansion 
driven by positive operating 
leverage and mix into higher 
margin products.

•  Strategic acquisition of Tennessee 
Industrial Electronics (T.I.E.) builds 
scale and gives access to the 
important industrial automation 
end market.

International Controls (51% of 
Controls Sector revenue) delivered 
15% organic growth in the year, 
benefitting from market share 
gains in recovering civil aerospace 
markets and structural tailwinds in UK 
defence and German energy markets 
as investment in these areas remains 
a critical focus for governments. 
The Sector also further penetrated 
exciting end markets within electric 
vehicles (EV), renewables and space. 
Operating margin increased strongly, 
primarily due to positive operating 
leverage on volume growth, and mix 
benefits from the acquisition of T.I.E. 
and disposal of Hawco.

Windy City Wire (49% of Controls 
Sector revenue) continues to perform 
strongly, with organic revenue growth 
of 7% in the year, following a very 
strong comparative period with 32% 
organic growth in FY22. Product 
range extension and share gains in 
new end market segments drove 
volume and a favourable mix. 

Adjusted operating profit 
increased significantly, 29% 
higher at £136.6m with a 250bps 
year-on-year increase in adjusted 
operating margin to 24.0%.

29%

REVENUE DIVERSIFICATION 
DRIVING ORGANIC GROWTH
The Sector continues to diversify its 
end markets, gaining share in space 
and telecoms and benefitting from 
the wider move to electrification 
and green energy as it continues 
to deliver growth in the EV and 
renewable energy end markets. 

We delivered strong double-digit 
organic growth in our Interconnect 
businesses, particularly in the 
German energy end market, 
driven by share gains and upgrades 
to the transmission and distribution 
network. Other key growth segments 
include defence, motorsport, 
aerospace and medical, where 
our businesses benefitted from 
momentum in these growing 
end markets and share gains.

Our Specialty Fasteners businesses 
delivered very strong double-digit 
growth during the year as they 
continue to win market share 
and benefit from strong customer 
demand in the recovering civil 
aerospace market in both the US and 
UK. We secured key contract wins in 
seats and cabin hardware and further 
diversified end markets with good 
momentum into space, unmanned 
aerial vehicles (UAVs) and electric 
vertical take-off and landing (eVTOL) 
aircraft. Geographic diversification 
has also been a theme in aerospace, 
with an important contract win 
in France for a major cabin and 
seating manufacturer.

 DIPLOMA PLC  ANNUAL REPORT 2023  −  27 

OUTLOOK
We have made good strategic 
progress in Controls. Our businesses 
are benefitting from initiatives to 
capture growth in structurally 
growing end markets, such as data 
centres, EV and energy, as well 
as high-growth emerging markets, 
such as space and eVTOL. We are 
also benefitting from continued 
geographic diversification as we 
continue to build scale in the US 
and Europe. We are taking share 
in markets in which we operate. 
The Sector has strong momentum, 
and we remain very positive about 
its prospects. 

Specialty Adhesives delivered 
strong double-digit growth in 
its key automotive end market as 
well as continued share gains in the 
telecommunications and EV markets.

WCW continues to drive strong 
growth and gain share in the high 
margin petrol station end market, 
where its products are essential 
to the new generation chip readers 
used to prevent fraud, and which  
are being systematically rolled 
out across the US.

TARGETED ACQUISITIONS 
TO ACCELERATE GROWTH 
During the year, the Sector 
completed the acquisition of 
T.I.E. for ca. £76m, providing it with 
access to the important industrial 
automation end market, which  
has been a strategic target end 
market for some time. T.I.E. also 
drives product extension (robotics 
and CNC machines) as well as 
deepening geographic penetration  
in the key US market.

Two smaller bolt-on acquisitions 
were completed in the year, with 
Eurobond further broadening our 
product offering in Specialty 
Adhesives, and Shrinktek expanding 
the Sector’s offering in UK Wire & 
Cable.

BUILDING SCALE
Significant investment in technology 
and facilities is underway as the 
Sector finalises the integration of 
its UK Wire & Cable locations into 
one state-of-the-art facility and 
a common ERP platform.

Sales resource has been added to 
the European Fasteners business as 
part of the strategy to expand in the 
civil aerospace market. Focused 
investments in sales resources are 
also being made into the adhesives 
market to capitalise on long-term 
aerospace and defence 
opportunities.

SPECIALTY ADHESIVES
  TECHSIL 

Techsil, based in the UK, sells 
specialty silicones, adhesives 
and sealants. It adds value 
through technical sales and 
support, own branding and 
technical specification.

Techsil is aligned with structurally 
growing end markets, such as EVs, 
through battery bonding and circuit 
board solutions, as well as the 
telecoms and defence industries.

A strong management team has 
enabled us to add two bolt-on 
acquisitions since Techsil joined 
the Group in 2021.

Techsil has significant opportunity 
across all of our growth buckets - 
UK consolidation, geographic 
penetration in the US and 
Europe, and exceptional 
end market potential.

SEALS SECTOR CONTINUED

TED MESSMER
CEO, NORTH AMERICAN SEALS SECTOR

“ I am so proud of the 
North American Seals 
team and all the progress 
they have made this year 
in strengthening our 
growth potential and 
broadening our  
value-add capabilities.”

ALESSANDRO LALA
CEO, INTERNATIONAL SEALS SECTOR

“ The International Seals 
Sector is poised for 
continued strong organic 
growth, augmented by 
the increased European 
footprint due to the 
acquisition of DICSA.”

2023 HIGHLIGHTS
•  Strong International Seals 

performance driven by R&G 
and Australian Seals. 

•  Resilient performance in North 
American Seals, benefitting 
from returns on the investment 
into the Aftermarket facility in 
Louisville and strong performance 
in our MRO business offsetting 
some destocking in certain 
OEM customers.

•  Adjusted operating profit increased 
by 26% to £79.0m (2022: £62.6m). 

•  Invested in scaling projects 
focusing on automation and 
supply chain efficiencies through 
facilities upgrades. 

•  Strategic acquisition of 

Distribuidora Internacional 
Carmen S.A.U. (DICSA) builds 
scale in Europe and broadens the 
product portfolio into stainless 
steel fittings, expanding 
addressable markets.

International Seals (56% of Sector 
revenue) delivered strong organic 
growth of 9%, principally driven by an 
excellent trading performance from 
R&G in the UK and strong recovery 
of capital projects in Australia.

North American Seals (44% of 
Sector revenue) delivered organic 
growth of 1% against a very strong 
comparator (2022: +16%) with 
strong growth in our North American 
Aftermarket and MRO businesses, 
partly offset by some destocking 
in some industrial OEM customers.

REVENUE DIVERSIFICATION 
DRIVING ORGANIC GROWTH
In International Seals, our UK 
Aftermarket business, R&G, grew 
strongly, benefitting from initiatives 
to diversify into product adjacencies 
and new end markets, such as 
wastewater treatment and potash 
mining. R&G has made a significant 
contribution to the organic growth 
of the Sector since acquisition, 
driven by strong sales into 
capital projects, particularly in the 
pneumatics and industrial markets, 
underpinned by solid MRO volumes.

Our Australian Seals businesses 
delivered very strong growth. 
This was driven by share gains and 
public infrastructure investments 
on the east coast, strong demand in 
anti-corrosion applications in the oil 
and gas industries, and continuous 
strong demand for the mining of 
raw materials for batteries. Anti-
Corrosion Technology (ACT), which 
was acquired in late FY22, has more 
than doubled since acquisition, 
capitalising on asset protection 
projects in the oil and gas industry.

We saw softer performance in our 
European OEM businesses where 
both medical and industrial end 
markets suffered some customer 
destocking. We expect this to 
moderate growth in the near term. 

North American Aftermarket 
delivered another year of strong 
growth. The investment in our 
Aftermarket facility in Louisville, 
extending service hours and product 
availability, is continuing to deliver 
accelerated growth and market share 
gains, particularly in western states. 
Very strong organic growth in the 
core repair market was boosted 
by the continuing focus on US 
infrastructure development.

The US MRO business delivered 
strong organic growth driven by 
high levels of demand for our 
proprietary products in the 
transportation market.

The US OEM business was softer, 
driven by destocking in a number 
of customers. We expect this to 
moderate growth in the near term.

TARGETED ACQUISITIONS TO 
ACCELERATE GROWTH 
During the year, the Sector acquired 
DICSA for ca. £170m, establishing 
a scaled platform in fluid power 
solutions across the European 
aftermarket. It adds to our 
established positions in the 
US and UK and over time will drive 
significant revenue and procurement 
synergies: cross-selling existing 
product from R&G, leveraging 
the Louisville facility to accelerate 
DICSA’s growth in the US, and 
enabling procurement synergies.

DIPLOMA PLC  ANNUAL REPORT 2023  −  31 

Also in International Seals, four 
bolt-on acquisitions were added into 
the R&G Group. Hedley and FPS 
bring complementary products and 
geographical expansion to R&G’s 
Hydraulics division. Valves Online will 
complement and strengthen R&G’s 
capabilities in the online route to 
market, as well as developing the 
valve product category. Lantech 
enhances the end market capabilities 
of the Industrial division with its focus 
on the food & beverage and 
pharmaceutical markets. 

In North American Seals, VSP 
acquired two businesses during the 
year, both creating cross-selling 
opportunities. GP&S, which supplies 
gaskets, seals, and fasteners; and 
Hex, which provides bolting and 
sealing training solutions to make 
manufacturing sites safer, more 
reliable and more profitable. 
Hercules OEM completed the 
bolt-on acquisition of ITG, a 
distributor of seals and adhesives for 
use in electrical connectors, valves, 
medical devices and industrial 
equipment. 

BUILDING SCALE
The Sector is selectively integrating 
smaller businesses to form better 
scaled platforms and during the 
year, completed the integration 
of TotalSeal into FITT Resources 
in Australia. 

Further scaling investments in 
facilities to establish national hubs are 
being made, with the construction of 
a new M Seals facility in Denmark that 
will become the Nordic hub for the 
Sector. In the UK, we have invested 
in a national distribution centre for 
hydraulic products and a centre of 
excellence for hose assemblies to 
position R&G as the national leader 
for these product ranges.

In North American Seals, we have 
focused on improving the supply 
chain; investing in facilities, talent 
and processes to improve supply-
demand planning and optimise 
inventory. The Sector continues 
to make major investments 
in warehouse automation and 
has successfully expanded the 
Autostore facility in Louisville.

OUTLOOK 
We have made good strategic 
progress in Seals in the year and 
the growth prospects for the Sector 
remain strong. The Sector is more 
resilient now than ever, supported 
by end segment exposures such 
as medical, food and beverage and 
renewable energy, and DICSA adds 
a scaled European operation to our 
existing US and UK platforms. 

Customer destocking has continued 
in our North American and European 
industrial OEM businesses and while 
we remain confident in their long 
term prospects, we do expect this 
to moderate Seals growth in the near 
term. We are well positioned to 
benefit from the significant 
investments into infrastructure 
projects across the US and Europe, 
which create a tailwind for growth 
across our Aftermarket businesses.

US MRO VSP 

TECHNOLOGIES 

Supported by their engineering 
expertise, VSP sells its customers 
solutions that reduce fugitive 
emissions and leakages and 
reduce downtime in mission-
critical and hazardous 
environments such as rail 
transportation of toxic materials. 

Their solutions reduce customer 
operating costs and have tangible 
environmental benefits. 

VSP Technologies offers 
customers fluid sealing solutions 
used in mission-critical and 
hazardous environments. 

When VSP Technologies was 
acquired in 2019, it sold custom 
gaskets used in chemical 
processing, power generation 
and other heavy industries. 

Since our acquisition, they have 
successfully broadened their flow 
control product lines, cross selling 
o-rings and hoses from other 
North American Seals Sector 
businesses, to VSP's existing 
customers.

LIFE SCIENCES SECTOR CONTINUED

TBC

PETER SOELBERG
SECTOR CEO, LIFE SCIENCES

“ Our Life Sciences Sector 
is well positioned for the 
continued growth, 
investment and adoption 
of new technology in the 
healthcare sector, which 
will support improved 
patient care.” 

Organic revenue +8%. The 
Sector has returned to growth 
with momentum accelerating, 
driven by the normalisation of 
surgical procedure and 
diagnostic testing volumes.

+8%

Our growth in Canada has been 
driven largely by implementation 
of technology and innovation by 
hospitals to address acute staffing 
shortages, with successful expansion 
in the urology, gynaecology and 
endoscopy specialties as well 
as technological adoption in 
laboratories and increased focus 
in interventional diagnostics testing. 

The Australian and New Zealand 
markets moved out of restrictive 
business conditions in January, 
resulting in increased activities 
in surgery case numbers (as staff 
availability improved), scientific 
projects and studies, and 
pathology testing. 

In Europe, our Irish and UK businesses 
continue to see growth in the In Vitro 
Diagnostics (IVD) segment and the 
scientific segment driven by 
improvement in technologies for 
R&D and manufacturing regulations. 
In the Nordics, we are well positioned 
to further expand into the critical 
care, surgical and gastrointestinal 
segments through national tender 
and contract wins. 

2023 HIGHLIGHTS
•  Organic revenue +8% (2022: -4%): 
The Sector has returned to growth, 
with momentum accelerating, 
driven by the normalisation of 
surgical procedure and diagnostic 
testing volumes despite ongoing 
healthcare staffing challenges. 

•  Positive outlook as governments 

act to address healthcare staffing 
shortages with automation and the 
associated increase in capital 
project funding.

•  Operating margins remain well 
ahead of our financial model 
but declined year-on-year, as 
expected, primarily due to a 
higher proportion of relatively 
lower margin capital sales; a 
full year effect of Accuscience 
(which has a lower margin with 
lower capital intensity); plus 
ongoing scaling investments.

•  Continued investments being 
made to build scale in the 
facilities and systems in 
Canada and Europe following 
the successful completion of 
the scaling project in Australasia. 

REVENUE DIVERSIFICATION 
DRIVING ORGANIC GROWTH
All businesses in the Sector have 
successfully diversified revenue 
streams to capitalise on the 
recovery of surgical and operating 
room procedures, as well as 
the increased funding for capital 
projects. During the year, we have 
secured new contracts across 
all regions as governments and 
hospitals increase capacity to clear 
the surgical backlogs and reinvest 
in new medical research laboratories.

New product introduction and the 
adoption of new technology were 
the primary drivers of growth in 
FY23. Growth has been driven by 
automated diagnostic testing in 
histology; molecular testing in 
infectious disease; haematology 
testing in oncology; AI-assistance 
in diagnostic & therapeutic 
endoscopy; single-use endoscopy 
in surgical urology procedures; 
and point of care patient 
monitoring and ultrasound.

 BUILDING SCALE
In Australia, we have successfully 
combined the operations of our two 
businesses to generate operational 
efficiencies, such as warehouse 
process improvements and freight 
consolidation. Similar projects are 
underway in the Canadian and 
European businesses, focusing on 
facilities and ERP systems. Together, 
these projects will build three scaled 
platform businesses to enable the 
Sector to capitalise on future growth 
opportunities. 

TARGETED ACQUISITIONS TO 
ACCELERATE GROWTH 
In July 2023 we acquired GM 
Medical in Denmark, distributing 
consumables and capital equipment 
for anaesthesia, critical care, surgery, 
obstetrics, neonatology, simulation 
and sterilisation. GM Medical is highly 
complementary to our existing 
Danish business, Simonsen & Weel.

OUTLOOK
With tailwinds from the recovery 
in surgical procedures, and 
increasing investment in pre-emptive 
diagnostics, the Sector’s growth 
outlook remains positive. All 
businesses in the Sector continue 
to focus on building their portfolio 
of products and services to broaden 
their value proposition to both 
suppliers and customers. 

FY24 will see a continuation of 
private and public laboratories 
investing to meet the growing 
demand for expanded diagnostics 
and screening utilising new 
automation and molecular testing; 
surgical and critical care capacity 
being rebuilt and expanded in 
healthcare systems; and drug 
and vaccine research and 
development, and companion 
diagnostics fields accelerating.

AUSTRALIA 

The Life Sciences Australia 
business navigate a highly 
technical and specialised 
environment in order to 
bring innovative surgical, 
pathology, and medical 
research products to market. 

Following an investment from 
Diploma, the Life Sciences 
Australia business has built 
capability and organisational 
strength by consolidating its 
facilities, third-party logistics, 
warehousing and ERP 
systems, bringing them 
all under one roof.

This has allowed the business 
to move from a generalised 
model to a specialised 
model, allowing them to bring 
in specialist talent to manage 
inventory, operations, service, 
and accounts. The new 
facility is also designed 
to support collaboration 
between teams. 

Another advantage of the 
move has been that clients 
are now able to visit the

demonstrations and see 
first-hand the logistical 
value-add benefits that 
are on offer.

Reported revenue increased by 
19% to £1,200.3m (2022: £1,012.8m), 
consisting of organic growth of 
8%, an 8% net contribution from 
acquisitions and disposals, and a 
3% benefit from foreign exchange 
translation. During the year, the 
Group disposed of Hawco, which 
contributed £15.1m to Group 
revenues in FY23 (2022: £30.7m).

Adjusted operating profit increased 
by 24% to £237.0m (2022: £191.2m) 
as the operational leverage from 
the increased revenue, disciplined 
cost management and accretive 
acquisitions drove an 80bps 
year-on-year improvement in 
the adjusted operating margin 
to 19.7% (2022: 18.9%). 

Statutory operating profit increased 
27% to £183.3m (2022: £144.3m), 
benefitting from a £12.2m profit on 
disposal of Hawco, compared with a 
net gain on disposal of £7.3m in the 
prior year relating to the disposal of 
Kentek and a1-envirosciences. 

Net adjusted finance expense 
increased to £20.4m (2022: £11.6m), 
principally due to the impact of 
higher interest rates, in particular in 
the second half of the year. Average 
gross debt remained broadly 
consistent with prior year with the 
proceeds from the equity raise in 
March being utilised, as intended, 
to finance acquisitions during the 
year. The all-in, blended cost of bank 
debt increased to 5.6% (2022: 2.8%). 

Adjusted profit before tax increased 
21% to £216.6m (2022: £179.6m). 
Statutory profit before tax was 
£155.6m (2022: £129.5m) and is 
stated after charging acquisition 
and other related charges, and 
acquisition related finance charges. 
Acquisition and other related charges 
of £53.7m (2022: £46.9m) principally 
comprise of the amortisation of 
acquisition related intangible assets 
of £52.9m (2022: £42.4m), £6.3m 
of acquisition related expenses 
(2022: £10.5m), £5.9m of fair value 
adjustments to inventory acquired 
through acquisition recognised in 
cost of inventories sold (2022: £nil) 
and partly offset by a net gain 
of £12.2m (2022: £7.3m) from 
the disposal of Hawco in the 
year. Acquisition related finance 
charges of £7.3m (2022: £3.2m) 
principally comprise of fair value 
remeasurement of put options for 
future minority purchases of £1.8m 
(2022: £1.4m) and amortisation 
and write-off of capitalised 
borrowing fees on acquisition 
related borrowings of £5.9m 
(2022: £1.4m).

FINANCIAL REVIEW CONTINUED

We are committed to being a 
responsible taxpayer and our 
approach is to comply with tax laws in 
the countries in which we operate and 
to pay our fair share of tax. The Group’s 
tax strategy was approved by the 
Board and is published on our website. 
The Group’s adjusted effective rate of 
tax on adjusted profit before tax was 
24.0% (2022: 25.0%) reduced from 
the year ended 30 September 2022 
largely due to non-recurring items 
from the prior year. 

Adjusted earnings per share 
increased by 18% to 126.5p 
(2022: 107.5p). Basic earnings per 
share increased by 19% to 90.8p 
(2022: 76.1p). An equity raise was 
completed in March 2023, resulting 
in a 7.5% increase (9,350,965 new 
shares) in the issued ordinary share 
capital. As at 30 September 2023, 
the average number of ordinary 
shares (which includes any potentially 
dilutive shares) was 130,260,868 
(2022: 124,855,007) and the 
weighted average number of 
ordinary shares in issue was 
129,675,581 (2022: 124,533,060). 

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 and 
the target level of dividend cover. 

For FY23, the Board has 
recommended a final dividend 
of 40.0p per share, making the 
proposed full year dividend 56.5p 
(2022: 53.8p). This represents a 5% 
increase in the full year dividend 
per share with a dividend cover of 
2.2x EPS, continuing the Group’s 
progressive dividend track record. 

CASH FLOW
Our capital-light business model, coupled with balance sheet and capital 
discipline drives strong and consistent cash conversion and ROATCE and 
maintains prudent leverage.

Free cash flow increased by 36% to £163.8m (2022:£120.4m). Statutory cash 
flow from operating activities increased by 42% to £257.3m (2022: £180.6m). 
Free cash flow conversion for the year was 100% (2022: 90%), ahead of our 
targeted 90%+ model, demonstrating the highly cash-generative qualities 
of our businesses and the results of targeted inventory reductions.

1  Net of cash acquired/disposed and including acquisition expenses, deferred consideration, and 

payments of pre-acquisition debt-like items. 

Depreciation and other non-
cash items includes £28.6m 
(2022: £23.9m) of depreciation and 
amortisation of tangible, intangible 
and right of use assets and £1.9m 
(2022: £0.7m) of other non-cash 
items, primarily share-based 
payments expense. 

Working capital increased by only 
£4.2m despite a 19% increase 
in revenue. This was largely driven 
by a £10.8m decrease in inventory 
as a result of strategic focus in this 
area as supply chain constraints 
have eased. 

Interest payments increased by 
£9.0m to £17.9m (2022: £8.9m) in 
line with increased interest charges. 
Tax payments increased by £2.2m to 
£41.4m (2022: £39.2m) with the cash 
tax rate reducing to 19% (2022: 22%) 
due to the timing of tax payments. 
Our effective cash tax rate remains 
lower than our Group effective 
tax rate, mainly due to acquisition 
goodwill which is deductible for 
US tax purposes. 

Net cash flow from acquisitions and 
disposals of £255.3m, which includes 
£6.0m of acquisition fees, comprises 
the spend for DICSA of £159.7m and 
T.I.E. of £75.1m; £23.7m principally 
relating to ten smaller bolt-on 
businesses; and £12.3m of deferred 
consideration relating to previous 
acquisitions; partly offset by net 
proceeds of £21.5m from the 
disposal of Hawco, a lower growth, 
lower margin business.

Capital expenditure increased by 
£16.1m, largely driven by scaling 
investments in Shoal Group, 
Hercules Aftermarket and R&G. 
FY22 benefitted from £9.9m of 
proceeds from disposal of property, 
plant and equipment. 

The Group funded the Company’s 
Employee Benefit Trust with £1.9m 
(2022: £2.8m) in connection with the 
Company’s long term incentive plan.

The Group received net proceeds 
of £231.9m from an equity raise 
completed in March 2023, to enable 
the refinancing of the acquisition of 
T.I.E., and provide greater flexibility 
to execute further acquisitions. 
Dividends of £70.8m (2022: £56.4m) 
were paid to ordinary and minority 
interest shareholders. 

This strong free cash generation has 
allowed the Group to deleverage 
more quickly than expected. 
At 30 September 2023, the Group’s 
Net Debt (excluding IFRS 16 lease 
liabilities) stood at £254.7m 
(2022: £328.9m). 

ACQUISITIONS ACCELERATE 
GROWTH
In fragmented markets, we 
deploy capital selectively and 
with discipline, to acquire quality 
businesses which accelerate 
strategic execution; build scale; 
broaden our portfolio; and 
accelerate organic growth.

The Group’s acquisition liabilities to 
shareholders of acquired businesses 
at 30 September 2023 reduced 
to £22.6m (2022: £31.4m) 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. 

•  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. These options are valued 
at £9.2m (2022: £7.4m), based 
on the latest estimate of EBIT 
when these options crystallise.

•  The liability for deferred 
consideration payable at 
30 September 2023 was £13.4m 
(2022: £24.0m). This liability 
represents the best estimate of 
any outstanding payments based 
on the expected performance 
of these relevant businesses 
during the measurement period. 
The reduction in the year is 
primarily due to the revaluation 
and settlement of deferred 
consideration for Kungshusen 
and R&G. 

Goodwill at 30 September 2023 
was £439.1m (2022: £372.3m). 
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 at the year end. 

DIPLOMA PLC  ANNUAL REPORT 2023  −  39 

ATTRACTIVE RETURNS
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 2023, 
the Group’s ROATCE increased by 
80 basis points to 18.1% (2022: 
17.3%). This increase was primarily 
driven by strong operating profit 
growth from the existing businesses, 
but was supplemented by the 
bolt-on acquisitions completed 
during the year which generate 
year 1 returns of 20%. This increase 
in ROATCE was delivered despite 
the dilutive impact of the DICSA 
and T.I.E. acquisitions which, when 
acquired with a combined 9x EBIT 
multiple, naturally constrain year one 
returns. We expect both of these 
acquisitions to reach 20% returns 
over the medium term. 

IMPROVED FUNDING
On 17 July 2023, the Group entered 
into a new committed multi-currency 
revolving credit facility agreement 
(RCF) with an aggregate principal 
amount of £555.0m. The RCF is 
due to expire in July 2028 with an 
option to extend for two further 
12 month periods. The RCF 
replaced the Group's previous 
debt facility agreement which as 
at 30 September 2022 comprised 
an RCF with an aggregate principal 
amount of £359.7m, an amortising 
term loan for an aggregate principal 
amount of £114.2m ($127.5m), a bullet 
term loan for an aggregate principal 
amount of £59.1m ($66.0m) and 
a further bullet term loan for 
an aggregate principal amount 
of £45.3m. 

At 30 September 2023, net 
debt of £254.7m (2022: £328.9m) 
represented leverage of 0.9x 
(2022: 1.4x) against a banking 
covenant of 3.5x (2022: 3.0x). 
The Group maintains strong liquidity, 
with year end headroom (comprised 
of undrawn committed facilities and 
cash funds) of £297m (2022: £204m).

PENSIONS
The Group maintains a legacy closed 
defined benefit pension scheme in 
the UK. In the year, the Group funded 
this scheme with cash contributions 
of £0.6m (2022: £0.6m) which 
increases annually on 1 October by 
2%. 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 (2022: 
£0.5m). Both schemes are accounted 
for in accordance with IAS 19. At 
30 September 2023, the UK defined 
benefit scheme was in a surplus 
position of £6.8m (30 September 
2022: £6.4m) reflecting a slight rise 
in corporate bond yields and a slight 
fall in the market’s expectation of 
future inflation. The Kubo scheme 
is not material.

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 FY22, the average 
Sterling exchange rate is weaker 
against the US dollar and the Euro, 
while stronger against the Canadian 
and Australian dollars. The impact 
from translating the results of the 
Group’s overseas businesses into 
UK sterling has led to an increase 
in Group revenues of £17.5m; an 
increase in the Group’s adjusted 
operating profit of £4.1m; and a 
reduction in net debt of £14.9m, 
compared with the same period 
last year. 

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 & 
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 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 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.

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 & Accounts.

INTERNAL CONTROL AND RISK MANAGEMENT

 MANAGING RISK

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.

OUR RISK MANAGEMENT FRAMEWORK

DIPLOMA PLC

BOARD OF DIRECTORS

AUDIT COMMITTEE

EXECUTIVE  
TEAM

LOCAL MANAGEMENT TEAMS

OUR BUSINESSES

Top down
The Group manages 
horizon scanning for 
emerging risks, review of 
principal risks, internal 
controls, processes and 
risk management 
frameworks. 

Bottom up
Our businesses 
continually identify risks 
and opportunities  
to feed into Sector and 
Group risk reviews.

IDENTIFYING AND MONITORING 
MATERIAL RISKS
Each of our Diploma 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. 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. 

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 on 
the hypothetical basis that there 
are no mitigating actions or controls 
to provide a score and then 
reconsidered to establish the net 
score after 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.

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.

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

DIPLOMA PLC  ANNUAL REPORT 2023  −  43 

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. 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. During the year, 'Climate 
Change', previously identified as an 
emerging risk, has been transferred 
to the Group's principal risk register 
and separated into the direct impact 
of adverse weather versus the impact 
of increased legislation in line with 
our TCFD climate assessment.

and the steps taken to mitigate 
them. These have been determined 
by the Board, using the robust risk 
evaluation described on the previous 
page, as having the potential 
to have a material impact to the 
performance, position or future 
prospects of the Group.

There have been some changes 
to the Group's principal risks 
during the year: 

•  Two climate-related risks: 
maximum legislation and 
maximum impact, have been 
added to incorporate our TCFD 
risk assessment.

•  Supply Chain has been 

disaggregated into loss of 
key suppliers and supply chain 
disruption given the differing 
nature of the mitigating actions.

•  Inflationary environment and 
foreign currency have been 
removed from the register of 
principal risks as they are part 
of the underlying operating 
environment, managed through 
standard operating procedures.

The Group's medium/high risks 
have been identified in the upper 
right four quadrants of the matrix. 
These risks and their corresponding 
mitigating actions are summarised 
in the table overleaf.

UNSUCCESSFUL 
ACQUISITION 

Risk category
Operational 

Board risk appetite
Cautious 

Change in risk 

The following are the key risks 
of an acquisition process:

•  The Group may overpay 

for a target.

•  The acquired business may 
experience limited growth  
post-acquisition.

•  Loss of key customers or 
suppliers post integration.

•  Potential cultural misfit as smaller 

businesses are faced with the new 
requirements of a listed Company.

The acquisition pipeline 
remains healthy and we 
retain our disciplined approach 
to acquiring high-quality, 
value-enhancing businesses.

The above may be the result 
of inadequate due diligence, 
poor integration or unrealistic 
assumptions used in the 
investment case.

FAILURE TO ATTRACT, 
RETAIN AND DEVELOP 
TALENT 

Risk category
Operational 

Board risk appetite
Cautious 

Change in risk 

The success of the Group is built on 
strong, self-standing management 
teams, which are committed to the 
success of their respective 
operating businesses. As a result, 
the loss of key personnel can have 
an impact on performance for 
a limited time period.

Not having the right talent or 
diversity at all levels of the 
organisation to deliver our 
strategy, resulting in reduced 
financial performance. 

This risk remains elevated 
due to tight labour markets 
affecting candidate availability 
and retention, upward pressure 
on wage levels in certain 
geographies, and changing 
expectations of working 
environments. 

Diploma has a strong history of 
executing a clearly defined, disciplined 
acquisition approach to acquire high-
quality, value-enhancing businesses.

The Corporate Development team is 
responsible for seeking and evaluating 
new acquisition opportunities with the 
Group Corporate Development 
Director reporting to the CEO.

A formal due diligence process is 
followed for every acquisition, with 
close supervision by the CEO, CFO 
and relevant Group senior management. 
A formal governance process is in place 
up to Board level.

A disciplined post-acquisition 
integration process covers operational, 
financial, governance, legal and 
reporting matters.

The Board reviews performance 
of recent acquisitions annually.

Contractual terms such as notice 
periods and non-compete clauses 
can mitigate the risk in the short term. 

The Group places very high importance 
on talent development, motivation 
and reward:

•  Ensuring a challenging working 
environment where managers 
feel they have control over, and 
responsibility for their businesses.

•  Implementing a structured 

talent review process for the 
development, retention and 
succession of key personnel.

•  Offering balanced and competitive 

compensation packages with 
a combination of salary, annual 
bonus, and long-term cash or 
share incentive plans.

•  Giving the freedom, encouragement, 

financial resources and strategic 
support for managers to pursue 
ambitious growth plans.

CYBER ATTACK

Risk category
Operational 

Board risk appetite
Cautious 

Change in risk 

The risk of cyber attacks 
remains high.

Group and operating business 
management depend critically on 
timely and reliable information from 
their IT systems to run their 
businesses and serve their 
customers’ needs. 

The decentralised nature of the Group, 
including stand-alone IT systems for 
each business, limits the potential 
impact to any individual business. 
There is good support and back-up  
built into local IT systems.

Any disruption or denial of service 
may delay or impact decision-
making if reliable data is unavailable. 

Poor information handling or 
interruption of business may also 
lead to reduced service to 
customers. Unintended actions of 
employees caused by a cyber attack 
may also lead to disruption, 
including fraud.

All businesses in the Group have a 
robust cyber security programme and 
we regularly engage with cyber security 
experts to continuously improve and 
strengthen our IT systems. 

A formalised ERP approval and 
implementation process ensures 
businesses have the most suitable 
IT systems to effectively manage 
their business.

Business continuity plans exist for 
each business with ongoing testing.

SUPPLY CHAIN 
DISRUPTION

Change in risk 

This risk is less acute than in 
the prior year, and our supplier 
relationships remain strong, 
supported by the ongoing 
rollout of our Supplier Code. 

The risk of manufacturing lead times 
increasing as a result of supply chain 
shortages or supply chain partners 
not operating to the same ethical 
standards as Diploma. 

We maintain strong relationships with 
suppliers and keep customers updated 
of any changes to retain key business. 

Meeting with key customers regularly 
to gain insight into their product 
requirements and market 
developments.

We work with our supply chain partners 
to help them meet our standards 
of acceptable working conditions, 
financial stability, ethics and technical 
competence. Our key suppliers are 
also asked to adhere to our Supplier 
Code. If they are unable to meet the 
standards expected then we will 
source product elsewhere.

LOSS OF KEY SUPPLIER

Risk category
Strategic 

Board risk appetite
Cautious 

Change in risk 

The continued growth and 
diversification of the Group 
effectively reduces the 
materiality of any loss 
of supplier.

The risk that a key supplier revokes 
a supply agreement and accesses 
the market through a competitor 
or directly.

In certain businesses there is a 
disintermediation risk where a 
supplier may go direct to market 
rather than via a distributor.

The key mitigation is the value-add 
service we provide to our supply 
partners, enabling them to access 
markets in the most efficient and 
effective way.

We continue to pursue diversification 
strategies and regularly seek 
alternative sourcing. 

Long-term, multi-year exclusive 
contracts have been signed with 
suppliers with change of control 
clauses, where applicable, for 
protection or compensation in 
the event of acquisition. 

The risk of increasing environmental 
legislation that adds cost or 
complexity to products and 
services and/or renders some 
products obsolete.

Board risk appetite
Tolerant 

Change in risk 

This is a new risk identified by 
our TCFD scenario analysis. 

Our businesses are close to their 
customers; have the technical expertise 
to specify compound materials; 
and enjoy long-term, meaningful 
relationships with their suppliers. 
We expect them to pivot and adapt 
in line with legislation. We have seen 
examples of this already, with North 
American Seals businesses promoting 
and identifying PFAS-free products 
to customers. 

Our Group has set net zero targets 
across our value chain. We expect 
our businesses to incorporate this 
into their value-add offering and see 
this as a competitive advantage for 
customers that wish to decarbonise 
their supply chain.

Given that many of our businesses are 
small-to-medium sized, few of their 
competitors have the same access 
and resources to analyse and progress 
against emissions reduction targets.

PRINCIPAL RISK

RISK DESCRIPTION AND ASSESSMENT MITIGATION

The businesses identify key market 
drivers and monitor trends and 
forecasts, as well as maintaining 
close relationships with key customers, 
who may give an early warning of 
slowing demand.

A number of characteristics of the 
Group’s businesses moderate the impact 
of economic and business cycles:

•  The Group’s businesses operate in 

three different Sectors with different 
characteristics and across a number 
of geographies and markets.

•  The businesses offer specialised 

products and services, which are often 
specific to their application, increasing 
customers’ switching costs.

•  A high proportion of the Group’s 
revenue comprises consumable 
products, which are purchased as part 
of the customer’s operating budget, 
rather than through capital budgets.

•  In many cases the products are used in 
MRO applications, rather than original 
equipment manufacture.

We continue to diversify our supply 
base and invest in product range 
development to mitigate exposure 
to any single market or region.

Adverse changes in the major 
markets that the businesses 
operate in can result in slowing 
revenue growth due to reduced or 
delayed demand for products and 
services, or margin pressures due 
to increased competition.

exposure to current geopolitical 
'hot spots' such as Russia and the 
Middle East.

Geopolitical events that could 
disrupt the Group’s operations 
include:

•  Interruption of trade agreements;

•  Change of trade or tariff 

relationships between countries 
in which we operate;

•  Government budget spending; 

and

•  Political elections.

DIPLOMA PLC  ANNUAL REPORT 2023  −  49 

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 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 2026. 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.

VIABILITY STATEMENT – DIPLOMA PLC
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 2026, 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 Directors confirm that this 
robust assessment also considers 
the principal risks facing the Group, 
as described on pages 44 to 48, 
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 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. 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 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 pages 157 - 
158. 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.

ENGAGEMENT WITH STAKEHOLDERS  
AND SECTION 172 STATEMENT

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.

S172 
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.

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 85 to 87 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.

 
DIPLOMA PLC  ANNUAL REPORT 2023  −  51 

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 79. 

Set out overleaf are some examples 
of decisions made by the Board 
in the year.

EQUITY PLACING  
In March 2023, following consultation 
with key shareholders, the Company 
raised 9,350,965 new ordinary 
shares, resulting in a 7.5% increase in 
the issued ordinary share capital with 
gross proceeds of approximately 
£236m. The Board was confident 
that the proceeds of the capital raise 
could be deployed against strongly 
value-enhancing opportunities, 
whilst maintaining rigorous discipline 
to capital allocation.

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. The 
Board was particularly cognisant that 
investors would want to understand 
how any acquisitions would fit within 
the existing financial framework and 
the impact, if any, on cash flow, and 
capital investment.

DELIVERING  
     FOR OUR PEOPLE

We are building an engaged and diverse workforce, 
who can reach their full potential as part of Diploma.

Our colleagues are the foundation 
of our business. They deliver for our 
customers, execute against our 
strategy and are essential to our 
ongoing success. It is critical that 
we continue to support 
their success. 

Developing our leaders at pace. 
Our businesses are run by our 
brilliant leaders. We must continue 
to develop them as our Group and 
businesses scale. 

Colleague engagement. 
Our colleagues have great technical 
expertise and in-depth knowledge 

of their customers and markets. 
Engagement helps us to retain that 
talent and nurture the unique 
culture that binds us. 

Developing our emerging talent. 
We must continue to deepen our 
breadth and depth of expertise in 
the areas that make the biggest 
difference to our businesses. 

We continue to focus on DEI  
to ensure that all our colleagues are 
given the opportunity to succeed.

1. COLLEAGUE ENGAGEMENT 
In 2023, we surveyed colleagues 
across the Group for the third time. 
We are delighted to have maintained 
our high response rate of 86%. Our 
overall engagement score increased 
to 80%, compared with 79% in FY22. 

There were some areas of standout 
success. 88% of colleagues told us 
they feel empowered to do their job. 
This was further supported by high 
scores relating to clarity on objectives 
at work, as well as our culture of 
teamwork and collaboration. 

belonging to an ethnic minority are 
as engaged, or more engaged than 
white, male colleagues. 

However, we are not complacent and 
recognise that there is more work to 
do. We need to continue 
strengthening communication ties 
and ensure colleagues have access 
to the learning and progression 
opportunities that come with a 
growing business. Every business 
is now working hard to co-create 
action plans informed by our 
colleagues’ feedback. 

We are proud to hear that women 
and colleagues identifying as 

Retention is equally important and 
we are pleased to have reduced our 

overall voluntary attrition by 4% in 
the last year (21.7% to 17.7%), this 
is especially significant given the 
context of the UK/US labour market.

2. DEVELOPING LEADERS AT PACE
Our decentralised model spans 
16 business units, three Sectors and 
multiple geographies. It’s a model 
that puts our customers at the heart 
of what we do, promotes local 
ownership, empowers our leaders 
to make the right decisions for their 
business, and drives a culture of 
accountability and ambition. The 
best decisions are made by leaders 
who are closest to our customers, 
employees and markets.

To ensure the success of this model 
we need exceptional leaders who are 
empowered to lead their business. 
This ownership, when coupled with 
our ambitious growth makes our 
people proposition very compelling. 

To accelerate the development 
of our leaders we have invested in 
bespoke leadership development 
targeted at supporting both Senior 
and Future Leaders as they consider 
how to Lead at Scale. 

It is an opportunity for us to build 
relationships across our global 
business and share best practice. 
Following the success of this year’s 
programme, which was attended by 
over 30 of our senior leaders, we will 
be extending the programme further 
across Europe, US and Australia 
during FY24.

3. MENTAL HEALTH & WELLBEING 
We are mindful of the potential 
impact that working environments 
and practices can have on our 
colleagues. 

Our businesses are very engaged 
in supporting the mental health and 
wellbeing of their colleagues. Many 
of our businesses now have trained 
mental health first aiders in place, 
whilst others have brought in 
external expertise to teach 
colleagues how to build resilience, 
improve communication and create 
healthy and sustainable habits. For 
other businesses, the focus is on 
building awareness - through ‘tea 
and toast’ sessions, Mindfulness 
Monday or a day every week 
dedicated to open discussion 
of mental health. 

ELENA

VP OF LIFE SCIENCES  
NORTH AMERICA 

I joined Diploma in 2004, when the 
business I worked for - Somagen 
Diagnostics - was acquired. In 
2009, I was appointed Managing 
Director and every year since has 
offered new challenges and 
successes as we’ve grown and 
scaled the business. 

I have recently been promoted 
to Senior Vice President, North 

America for the Life Sciences 
Sector. It’s an exciting and 
rewarding role, with many 
opportunities ahead. 

During my time at Diploma, I’ve had 
the opportunity to focus on talent 
development and diversification 
of our businesses. I’ve enjoyed 
working with our colleagues to 
develop exceptional talent 
within the Sector and it has been 
rewarding to work with my team 
to build purpose and culture.

4. DEVELOPING OUR 
EMERGING TALENT 
We know that the successful 
development of emerging talent is 
key to the future of our companies 
and that is why we are particularly 
proud of our apprenticeship 
programme. 

For many of our businesses, 
apprentices are a key source of 
talent. We work hard to support, 
develop and upskill our apprentices, 
who often remain with the Group 
for decades, adopting a number 
of roles including, in some cases, 
Managing Director. 

During the year, we also worked 
to retain and develop key talent 
by facilitating movement between 
businesses and secondment of roles 
into businesses.

We continue to actively work with 
our businesses to ensure people 
development is high on the agenda, 
and we are helping to build out local 
plans that play an important role 
in ensuring that we have strong 
succession pipelines to support 
our future growth and scale. 

CELEBRATING  
 OUR  
   APPRENTICES 

We were delighted to welcome our UK apprentices 
to the Diploma PLC office to celebrate National 
Apprenticeship Week in March this year. 

Apprenticeship schemes play a huge role in developing 
and retaining talent across our businesses. 

At our M Seals UK division, 24% of colleagues are either 
current or former apprentices and 85% of the shop floor 
team joined as apprentices or school leavers. 

5. CONTINUED FOCUS ON 
DIVERSITY AND INCLUSION
Diversity and inclusion is a 
competitive advantage that can help 
our businesses grow. We have set an 
ambition that all our colleagues feel 
able to bring their full selves to work, 
fulfil their potential, and benefit 
from working as part of a diverse 
team. To realise that vision, we 
must attract, retain and develop 
a diverse workforce.

Gender balance - we recognise that 
we have more to do to drive diversity 
across our senior team and this is 
why we have set ourselves the goal 
of gender parity by 2030. This year 
our Senior Leadership Team is made 
up of 28% women, up from 27% in 
2022. Our continued focus is 
producing results – we recently 
promoted two female leaders to 
our Life Sciences Executive Team. 

We have conducted listening 
groups with over one hundred 
women across the Diploma business 
to hear first-hand their experiences 
and insights. As a result we will be 
designing and implementing a global 
Women in Leadership programme 
that will be implemented in FY24 
and will support the accelerated 
development of female talent 
across the Group. 

We will also focus on supporting our 
businesses to hire for diversity - 
including how to attract and hire.

Recognising the importance of 
support for mothers returning from 
maternity leave, we are delighted to

mothers returning to the workplace.

Fostering inclusion - we continue 
to focus on fostering a culture of 
inclusion and community. We were 
pleased to see this reflected in the 
results of our recent colleague

It is humbling to see how our 
companies continue to build 
inclusive businesses and support 
our people so they can drive the

Ensuring the highest standards of ethics, safety 
and conduct across our Group. 

Keeping our colleagues healthy, 
safe and well is a prerequisite to 
doing business. We have a duty of 
care to any person who is working 
remotely, working at, or visiting 
a Diploma business.

We have outlined a vision that no 
one should be harmed at work. In 
order to achieve this, we will focus 
on risk mitigation and a proactive 
Health & Safety culture.

Management of our supply chain 
is key to our broader social and 
environmental impact as a Group, 
and a key part of our strategy and 
commercial proposition. Our focus 
will be to work with our suppliers to 
tackle climate change and reduce 
our own impact through more 
sustainable packaging, logistics 
and products.

a critical component supplier 
or a non-substitutional supplier. 

The standards of our Supplier Code 
ask our key suppliers to commit to 
conducting their business according 
to ethical, professional and legal 
standards including those relating 
to human rights, labour laws,  
anti-bribery and corruption 
and international trade laws and 
sanctions. We also ask our suppliers

Giving Back
Giving back is important to Diploma 
and this year we’ve seen a number of 
creative initiatives across the Group  
to support local communities and 
fundraise for charities that are 
important to our colleagues.

In line with our decentralised model, 
charitable initiatives are driven by 
the businesses and matched through 
Diploma’s fundmatching scheme. 

During the year, charitable donations 
across the Group totalled £54,000. 
No political donations were made.

Our focus for FY24 will be to embed 
the Diploma 'Stand up for Safety' 
framework to ensure a consistent 
approach to Health & Safety 
across all businesses. To support 
implementation of the framework, 
we will introduce workshops and 
enhanced training to ensure strong 
safety leadership and effective 
standards and governance, 
supported by third party audits. 

We remain committed to the 
ongoing safety and wellbeing of 
all colleagues, and will continue to 
support our businesses and business 
leaders in reaching our long-term 
objective of zero harm. 

Health & Safety
In line with our decentralised 
model, our Managing Directors are 
accountable for Health & Safety 
in their businesses. Each business 
works to build a strong Health 
& Safety culture, driven by the 
Managing Director and upheld 
by all colleagues. 

Our Group CEO holds ultimate 
responsibility for Health & Safety 
across the Group, including ensuring 
good governance and provision 
of a safe working environment 
for all colleagues. 

Businesses are responsible for 
developing and implementing 
procedures and frameworks to 
suit their specific circumstances 
and risk level. However, we expect 
all businesses to comply with the 
standards and requirements of 
our Group policy. 

Our guiding principle is that no one 
should be harmed at work. In order 
to achieve this, we have focused 
on identifying and mitigating risks.

Our Health & Safety KPI is our Lost 
Time Incident (LTI) rate, defined 
as Lost Time Incidents per 1,000 
employees. An LTI is defined as any 
incident in which time is lost beyond 
time taken for on-site first aid. 

During FY22, we set a target of 
5% year-on-year reduction in the 
LTI rate. In FY23, we recorded a total 
of 27 LTIs and an LTI rate of 9.5. This 
represents a 10% decrease on the 
FY22 rate of 10.6. There were no 
fatalities in the year. 

The majority of our LTIs relate to 
operations of our warehouses, such 
as manual handling, slips and trips. 
We have identified further areas of 
increased risk from poor use of 
equipment and programmes are 
being implemented to address this.

DELIVERING   
     FOR THE   
   ENVIRONMENT

We are delivering against our net zero ambitions 
and positioning the Group to contribute positively 
to a low-carbon economy. 

The climate crisis is urgent and 
global, we recognise the impact 
of our value chain and the 
narrowing window of opportunity 
to make a positive contribution in 
tackling this crisis. Beyond the 
moral obligation that we feel, 
we also see how taking action 
can contribute to long-term value 
creation and the growth of our 
businesses.

Our colleagues are increasingly 
passionate about climate change 
and expect the Group to drive 
progress and support business 
initiatives. There is also the 
opportunity to deliver value 
to our customers by offering 
more sustainable products and 
solutions, building our knowledge 
and expertise, and working to be 
a more carbon-efficient business 
that can in turn support their net 
zero goals.

UNDERSTAND
As a decentralised 
Group, ensuring 
that businesses are 
engaged and equipped 
with the knowledge 
and support they need 
to effect change, is key 
to our success.

PROCURE
Procurement of 
renewable energy, 
in the short term, 
is a useful means of

it is both responsible 
and transparent.

SETTING NET ZERO TARGETS
We have calculated our Scope 3 
emissions for FY22, using a cost-
based methodology. These have 
been submitted to the SBTi, where 
they are awaiting validation. 

We have set a near-term target of 
50% reduction of absolute Scope 1 
and 2 emissions by 2030 from an 
FY22 base year. We also committed 
to reduce our absolute Scope 3 
emissions by 30% within the same 
timeframe. Our long-term target is 
to reduce absolute Scope 1, 2 and 3 
GHG emissions 90% by 2045 from 
an FY22 base year. 

SCOPE 1 & 2
During FY23, Scope 2 represented 
60% of our operation emissions. 
During the year, our businesses 
continued to install LED lights, EV 
chargers and change processes 
to improve efficiency. We also held 
workshops across the businesses 
to align on our net zero strategy. 

Categories 4 and 9, which relate to 
upstream and downstream transport 
and distribution are in aggregate 
responsible for 34% of Scope 3 
emissions. Where possible, we will 
shift air freight to lower emission 
options, such as shipping or rail, 
and select road freight partners 
with electric fleets. 

SCOPE 3
Scope 3 emissions are the most 
material GHG source for the Group, 
accounting for 97% of total FY22 
emissions. Of the 15 categories 
considered, Category 1: Purchased 
Goods & Services is 51% of Scope 3. 
Our focus will be to engage suppliers 
on their emissions initiatives. 

EMISSIONS INTENSITY
Emissions intensity decreased 
from 7.4 to 7.2 indicating that gross 
emissions from existing businesses 
remained flat despite an increase in 
revenue.

As part of our ESG programme, Delivering Value Responsibly (DVR), we have an established 
governance structure in which the Board has ultimate oversight of, and responsibility for, 
climate-related risks and opportunities (CRROs). The Group’s Executive Directors, who are 
both members of the Group DVR Steering Committee, are responsible for the delivery of the 
Group’s DVR strategy (which includes the management of CRROs) and are the sponsors of its 
2045 net zero ambitions. 

We have a fully embedded risk management framework, which is overseen by the Board and 
the Group CFO, and includes the analysis of CRROs and their materiality to the Group. 

They are supported in this by:

TASKFORCE ON CLIMATE-RELATED FINANCIAL DISCLOSURES (TCFD) CONTINUED

GOVERNANCE CONTINUED

The Board is kept informed on all relevant matters, including climate-related issues, in a 
number of ways, including: monthly reporting packs, covering financial and non-financial 
performance; regular Board meetings, which include CEO updates on DVR and climate-
related strategy and performance; an annual, in-depth DVR update from the Group 
Sustainability Director; annual deep-dive reporting on macroeconomic trends, including 
the risks of climate change; quarterly climate risk updates, including a review of the Group’s 
climate risk management. 

The Board considers climate-related issues when reviewing and guiding strategy, major plans 
of action, risk management policies, annual budgets and business plans as well as setting the 
organisation’s performance objectives, monitoring implementation and performance and 
overseeing major capital expenditures, acquisitions and divestitures. 

The Board has practical experience in implementing ESG strategies. They supplement this with 
external expertise. During the year we engaged external consultants to support on emissions 
reporting, including Scope 3, net zero target setting, and qualitative risk scenario modelling.

RISK MANAGEMENT

Our businesses have in-depth knowledge of their customers, industry, products and 
services, and our decentralised model empowers them to manage and make decisions 
locally. We consult our businesses and Sector management in identifying and assessing all 
risks, including CRROs, supported by expertise and knowledge from relevant functions and 
Group departments. 

In FY23, we undertook a qualitative scenario analysis to identify principal CRROs. 
We involved operational, business and functional leaders across the Group, supported 
by external, independent expert consultants. The CRROs were assessed using a 
Probability-Impact Matrix to consider the likelihood of the CRRO materialising over 
the different timeframes, and the potential impact and materiality to the Group.

Following the identification of key CRROs, we considered the materiality of their impact on 
the Group over time (short, medium and long-term horizons). We assess materiality against 
climate-related risks on a 'net basis' after consideration of mitigating factors or actions.

•  Short to medium-term risks: materiality determined at higher than 5% of the Group’s 

adjusted Profit Before Tax (in line with our Financial Statement audit methodology) in the 
respective year of the most recent long-term strategic plan. Short-term refers to the time 
period up to 2030, medium-term refers to the time period between 2030-2040.

•  Long-term risks: we apply 2x the materiality levels of short to medium-term risks. This 
reflects likely continued growth of the Group, greater uncertainty over time, and time 
available for mitigation planning. Long term refers to the time period between 2040-2050.

This process will be refreshed annually to ensure that the material climate-related risks 
and opportunities continue to be relevant and appropriate to the Group. 

CRROs are managed in line with our decentralised culture and DVR and Risk Governance 
frameworks. Climate risk management is fully integrated into our risk management process.

STRATEGY 

In order to identify relevant CRROs, we considered the following scenarios, which allowed us to consider the impacts 
of likely physical and transitional outcomes. We considered the impact of climate regulation and physical impacts 
across our key geographies and sites, including those of our suppliers. We considered changing markets and the 
impact on our customers and suppliers.

RCP SCENARIO

Description

FOSSIL-FUELLED GROWTH

STEADY PATH TO SUSTAINABILITY

More extreme weather events due to 
extremely limited decarbonisation efforts

Globally coordinated decarbonisation 
to achieve net zero by 2050

Mean temperature rise by 2100

4 degrees celsius

2 degrees celsius

Fossil-fuelled growth scenario - overview
Global collaboration is focused on mitigation, rather than reducing climate change, resulting in an increase 
of extreme weather events as the current warming rate continues unabated. Temperatures exceed the warming 
rate of 4 degrees by the end of the century, as projected by the IPSS’s worst case RPC 8.5 scenario. 

Steady Path to Sustainability scenario - overview
Globally coordinated efforts to reduce emissions to net zero by 2050. This limits the global temperature increase 
to 2 degrees above pre-industrial levels, as projected by the Intergovernmental Panel on Climate Change’s (IPCC) 
RCP2.6 scenario.

FOSSIL-FUELLED GROWTH SCENARIO 
We assumed a range of extreme weather events occurring with increasing frequency across the short, medium and 
long term, and the potential damage to our distribution centres and offices due to flooding, extreme heat, wildfires 
and storms. We reviewed 10 of our most significant locations, covering ca. 60% of the Group’s total revenue. 
Mitigation – such as property or business interruption insurance and buffer stockholding in place – would 
significantly reduce any financial impact.

We identified the highest physical risk and impact would be due to hurricanes at our Hercules Aftermarket site, 
located in Louisville. However, there are preventative disaster recovery plans and insurance in place to mitigate 
against those risks. 

The financial impact of the risks identified in this scenario would not be material due to: 

•  The broad geographical spread of the Group;

•  Diversified physical assets, customers and suppliers, with low commercial dependencies (largest customer 

and supplier represent 1% and 5% of revenue respectively); 

•  Our distribution centres are not typically located in high-risk areas. Whilst there may be very short-term disruptions 
on a very localised basis, it would only affect a few, small locations with insufficient frequency to have a material 
financial impact, post-mitigation. 

We will continue to monitor the impact physical risks have on our operations as part of our future financial planning.

STEADY PATH TO SUSTAINABILITY SCENARIO 
We considered the risk of changing regulation and/or customer demand, in the context of the Group’s 2045 net zero 
target. This scenario identified our most relevant CRROs, which we have outlined below, including their impact on the 
Group’s business, strategy and financial planning. We have performed a quantification of the financial impacts to the 
Group based on the relevant timeframes. Whilst our assessments show that the financial impacts of these CRROs are 
low, our financial statements and viability assessments nevertheless reflect our best estimate of the impact of 
climate change on future business performance and the carrying values of our tangible and intangible assets, based 
on currently available information and taking into account the planned mitigation measures. We have also considered 
the resilience of the Group’s strategy against these CRROs, including potential mitigations as well as actions to 
capitalise on the material climate-related opportunities.

TRANSITIONAL RISK

MATERIALITY OF RISK

MITIGATION

Policy & Legal / Market: 

Timeframe: medium term

Financial impact: low

The fragmented product 
decarbonisation policy landscape 
also has the knock on impact 
of making products more 
expensive and uncompetitive 
in less environmentally ambitious 
markets, whilst posing a potential 
risk if suppliers lack regional 
decarbonisation incentives.

The EU’s proposed ban on PFAS may 
have the impact of increasing the 
cost of seals that incorporate raw 
material alternatives to PFAS to be 
sold into the EU market, but also 
seals that originate from the EU 
to be more expensive in other 
territories that have not imposed 
the PFAS ban. 

The failure to adapt our products 
would mean a reduced ability 
to sell certain products into 
jurisdictions where demand 
for sustainable goods is high, 
potentially reducing revenue and 
affecting our competitiveness.

Product decarbonisation due to 
stricter climate policies and market 
shifts

As a global company, we will likely 
face differing and localised 
environmental policies and 
legislation across our key 
geographies. We also expect them 
to be introduced and implemented 
at a different pace. Meeting these 
higher standards is extremely 
important to ensure we can 
successfully and compliantly 
operate in those geographies. 

One specific identified risk in 
product decarbonisation is the 
EU’s proposed ban on synthetic 
chemicals such as polyfluoroalkyl 
substances (PFAS), which is relevant 
to our Seals business, where ca. 6% 
of the Group’s revenue is generated 
from seals that include PFAS. 

From a market perspective, 
a significant proportion of our 
downstream market is subject 
to considerable emissions scrutiny. 
It is therefore likely that we will be 
expected to reduce the carbon 
intensity of our sold products to 
support our customers in meeting 
their own sustainability goals.

As a consequence, it will become 
vital to obtain emissions data and 
encourage product decarbonisation 
from our suppliers, especially in less 
sustainability-focused countries, 
given our role as a value-added 
distributor. 

As a global Group, we benefit 
from knowledge sharing – those 
businesses that have navigated 
stricter or faster-moving legislation 
will enrich the Group experience and 
provide case studies and learnings 
that will benefit other businesses.

As a decentralised Group, our 
businesses are close to their 
customers, have the technical 
expertise to specify compound 
materials, and enjoy long-term, 
meaningful relationships with their 
suppliers. We expect them to pivot 
and adapt in line with legislation. 
We have seen examples of this 
already, with North American 
Seals businesses promoting and 
identifying PFAS-free products 
to customers. 

Our Group has set net zero targets, 
including against Scope 3 emissions. 
We expect our businesses to 
incorporate this into their value-add 
offering and see this as a competitive 
advantage for customers that wish 
to decarbonise their supply chain. 
Given that many of our businesses 
are small-to-medium sized, few of 
their competitors have the same 
access and resources to analyse 
and progress against emissions 
reduction targets.

TRANSITIONAL RISK

MATERIALITY OF RISK

MITIGATION

The Group has previously navigated 
rising supply chain costs by 
successfully passing costs 
on to the customer. 

Policy & Legal

Decarbonisation costs

A shift towards decarbonisation 
could see increased operating costs 
particularly in relation to purchased 
inventory as well as logistics costs. 
This could largely be influenced by 
the tightening of environmental laws 
and regulations in relation to carbon 
pricing globally. Carbon pricing 
instruments can take many forms, 
with the most common being 
carbon taxes, taxes on fuels 
and trading schemes or levies. 

Timeframe: short, medium and  
long term

Financial impact: low

The risk of new regulation 
manifesting in the EU via the carbon 
border adjustment mechanism 
(CBAM) for example, could see 
product costs increasing. There 
is also a risk that products will 
increase in cost as raw materials 
such as precious earth metals 
become more expensive to procure 
due to scarcity, increased demand 
and government regulation. 

Inbound and outbound logistics 
cost is ca. 34% of our Scope 3 
emissions. There could be increased 
costs associated with carbon freight 
taxes and low-carbon technologies 
implemented through either 
government regulation or 
investments by our logistics 
partners in sustainable alternatives.

POTENTIAL BENEFIT

Timeframe: short, medium and long term

Product and market opportunities

Prolonging product lifespans is at the core of the circular 
economy. With a significant portion of our products 
catering to repair, maintenance and refurbishment, 
we inherently contribute to our customers’ machinery 
longevity. Circularity is a core part of our business 
model. The ability to manage, reuse and recycle waste 
products and by-products is a competitive advantage.

As the global economy transitions to a low-carbon 
model (albeit at varying rates), there are opportunities 
to grow revenues across a range of new customer 
segments, including adaptation infrastructure and 
renewables. As economies decarbonise, new 
opportunities are likely to emerge.

Our recent acquisition of T.I.E. exemplifies how we 
are pivoting to more aftermarket and repair service 
opportunities. We will use T.I.E. and existing 
aftermarket businesses as a platform for further 
growth in this segment.

The transition to a lower-carbon economy and its 
impact on industrial design should lead to significant 
opportunities for new customers and segments for 
the Group. We have a strong process to assess and 
capitalise on new market opportunities. In our budgeting 
and strategic planning process, all businesses identify 
transitioning industries and strategies to access these 
new markets. We are already seeing this growth in 
market segments with our Australian Seals business 
securing its largest service contract to remove, repair 
and reinstall pump equipment for a national water 
company. 

Policy & Legal / Market: 

Timeframe: medium 

Lower transportation costs, including decreased 
fuel use, transport miles and associated emissions and 
taxes through route optimisation, reverse logistics, fuel 
efficiency, consolidated supply chains, a move to local 
suppliers, combined shipments and other efforts to 
decarbonise transport and logistics. 

Enhanced logistics efficiency

Through sustainable supply chain management we 
can simultaneously reduce costs through more efficient 
distribution and improve our reputation with customers 
who are increasingly interested in greener product 
deliveries. This can also enhance access to new 
customers looking for more sustainable distribution 
options, including those looking to reduce their 
Scope 3 emissions. 

Our aim is to pass on efficiencies to our customers 
and market our sustainable approach to customers 
interested in reducing their value-chain emissions.

We have started to collect data on our inbound and 
outbound logistics and work closely with our customers 
and third-party couriers to reduce their emissions and 
improve efficiency. 

We are currently doing this by consolidating orders 
into less frequent shipments and driving model shifts 
where possible.

Resilience of the Organisation’s Strategy
Our strategy enables us to remain resilient to CRROs:

•  Our decentralised model means that our businesses retain their in-depth product 

knowledge, understanding of local markets, and strong customer and supplier relationships. 
This enables us to respond quickly to changes in regulation, market and technology; 

•  Our low customer and supplier dependencies ensure that any identified risks are 

sufficiently diversified;

•  Our value-add and pricing discipline allows us to pass on the impact of decarbonisation 

costs to protect our margins;

•  Our organic growth initiatives capture opportunities relating to a decarbonising economy, 

supporting our transition away from markets that are at risk due to decarbonisation;

•  DVR is embedded across our Group, ensuring that our businesses are aligned on our net 
zero target and are driving action and emissions reductions across every aspect of their 
business;

•  Our low capital intensity model gives us the versatility to transition with little risk 

to asset values.

As part of our Supplier Code, we continue to work with our suppliers to align on our emissions 
reduction ambitions and intend to expand the Scope of our Supplier Code in order to drive 
Scope 3 emissions reductions with our product and logistics suppliers.

METRICS & TARGETS
A summary of our Group emissions

The Group measures and monitors the following key metrics. Below we have outlined those 
that are relevant to our identified CRROs. A summary of the below metrics, KPIs and relevant 
targets can be found on pages 54-66. 

Emissions
Reducing our absolute emissions is a key driver to achieving our 2045 net zero target. 

Waste
Although waste does not represent a material proportion of our emissions footprint, 
we nevertheless see it as potentially significant in terms of business reputation, efficiency 
and circularity.

Supplier Code
We see supplier engagement and the future alignment of our Supplier Code to our 
Scope 3 targets, as fundamental to our net zero strategy. 

Financial metrics
Financial performance targets are set as part of the budget, which incorporate the revenue, 
profit and cash flow impacts of CRROs. The financial performance targets form a material 
element of the short-term variable bonus schemes as well as the longer-term performance 
share plans. 

We actively monitor revenue that comes from both the physical and transitional impacts 
of climate change – such as renewable energy generation, circularity or fugitive emissions – 
as well as our social impact. 

In addition, the three-year strategic plan and the annual budget includes opex and 
capex investments related to our CRROs. All scaling projects are now scrutinised for their 
environmental impact, taking advantage of these projects to make step changes towards 
meeting our environmental targets and incorporates the respective financial investments 
required to enable this. A similar process is in place and applied to due diligence and business 
plan preparations for new acquisitions, e.g. T.I.E. and DICSA acquisitions in FY23. 

More detail on these targets and the performance against them is set out on pages 54 to 66.

“ The high standards of corporate 
governance underpin everything 
we deliver.”

DEAR SHAREHOLDER, 
On behalf of the Board, I am 
delighted to present the Company’s 
Corporate Governance Report for 
the year ended 30 September 2023, 
which summarises how the Board 
and our governance have provided 
leadership over the year in support 
of the long-term sustainable success 
of Diploma. Diploma has grown 
consistently over the last few years 
and our governance has continued 
to evolve accordingly to provide 
confidence to our investors and 
allow our entrepreneurial businesses 
to develop further. 

Corporate governance is the 
predominant framework in which 
companies build trust with their 
stakeholders, and the wider 
community. It is more than just 
the principles that safeguard a 
company’s interests, but a way to 
create long-term value. Corporate 
governance in itself is not a direct 
value driver, but can facilitate or 
hinder the creation or protection of 
value. Forward-looking organisations 
are able to focus on growth and 
value creation through the 
development of strong corporate 
governance practices. We must 
also go beyond the balance sheet, 
reporting intangible value and 
investing in our employees' 
development to grow alongside  
their businesses. 

Sustainable corporate governance 
focuses on tackling environmental 
issues, evolving supply chains, 
improving diversity in the workforce, 
as well as contributing to the local 
communities. The Board is pleased 
that our corporate governance 
thinking and approach have 
continued to grow and evolve 
alongside the growth of our 
businesses. Throughout the last 
few years, we have continued 
to develop and embed our 
Delivering Value Responsibly (DVR) 
frameworks. Further information on 
our sustainability programmes can 
be found on pages 54 to 66. 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 optimal 
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 
very pleased to witness this culture 
in person during our visits this year 
to our Life Sciences businesses, 
Simonsen & Weel in Denmark 
and Acernis Medical in Canada.

We will continue to refine and 
develop our governance processes 
to ensure robustness and efficiency 
at Board level and throughout the 
Group, in a way that enables the 
creation of sustainable long-term 
value for our shareholders and 
other stakeholders.

BOARD SUCCESSION 
AND EVALUATION
Board composition and succession 
remain key areas of activity and 
focus. Anne Thorburn and Andy Smith 
will be retiring in 2024 after nearly 
nine years of service each. During 
the year, our Nomination Committee 
oversaw the succession and 
appointment process for a 
suitable candidate to take over 
the Remuneration Committee Chair 
position and were pleased to appoint 
Jennifer Ward as Remuneration 
Committee Chair-Designate on  
1 June 2023. Jennifer brings a wealth 
of knowledge and experience to 
the Board and is an important part 
of its continued evolution. The 
Nomination Committee has begun 
a search process for the role of 
Audit Committee Chair and an 
announcement will be made at 
the appropriate time.

Strategic ReviewCorporate GovernanceFinancial StatementsOther Information78  −  DIPLOMA PLC  ANNUAL REPORT 2023

CHAIR'S INTRODUCTION TO GOVERNANCE CONTINUED

The Board’s priorities for FY24 remain 
consistent, with a continued focus 
on: the implementation of the 
Group’s strategy; challenging 
and empowering management; 
succession planning; and 
management of risk. Your 
Board is well placed to execute 
its stewardship role to ensure that 
the Group continues to evolve, 
scale and deliver long-term 
sustainable growth. We will also 
continue to be agile, adapting 
our thinking and priorities and 
promoting the interests of our 
investors, employees and other 
stakeholders over the coming years.

Our AGM will be held on 17 January 
2024. 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. 
You can contact us via the Group 
Company Secretary.

David Lowden
Chair

The Board is keenly aware of the 
need for diversity and inclusion, 
which is a key component of the 
Group’s DVR programme. Following 
the appointment of Jennifer Ward 
in June, as at the end of the Financial 
Year the Board is 37.5% female, 
which does not meet the target 
by the Financial Conduct Authority 
that 40% of Board members are 
to be women. We do meet the 
recommendations requiring 
women to occupy at least one 
of the Board’s senior roles. 

Gender diversity in the wider senior 
management and wider workforce 
remains a key focus as expanded 
upon on pages 56 to 59. The 
Board will continue to set the right 
conditions and lead by example 
through its own approach to inclusion 
and diversity across its composition; 
further information can be found in 
our Nomination Committee Report 
on pages 96 to 101.

A key aspect of good governance is 
for the Board to critically self-analyse 
itself, its members and Committees, 
in order to continually improve its 
effectiveness. The Board carries out 
effectiveness reviews annually, and in 
FY23 this was undertaken internally in 
line with the Code. 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 101. In FY24 we will 
undertake an externally facilitated 
evaluation and look forward to the 
opportunity for candid self-
reflection.

BOARD OF DIRECTORS CONTINUED

MONITORING CULTURE

PURPOSE, CULTURE AND VALUES
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. In reviewing and 
ensuring the implementation of the 
Group’s strategy, the Board ensures 
that the objectives of our purpose 
are met while also taking into 
account the risks and opportunities 
facing the Group.

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. Our 
decentralised model means 
that culture is embedded in our 
businesses, each of which has 
its own unique aspects which we 
believe are critical to the autonomy 
and empowerment that underpins 
the Group’s success. As the business 
landscape evolves and the Group 
continues to grow, the Board felt 
it necessary to review the Group’s 
culture and values during the year to 
ensure continuity, adaptability and 
the right cultural direction. Following 
this review, we refreshed our core 
values to be: customer-centric, 
doing the right thing, remaining 
accountable, growing together 
and being down to earth.

During the year, the Board has 
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. 
Successfully scaling up our value-
add model requires constant 
evolution, and our culture has a 
critical role to play in supporting 
growth. When considering 
acquisition strategies, cultural fit 
is also an important area of focus 
and discussion. Whilst remaining 
decentralised and maintaining their 
own unique identity, our businesses 
benefit from shared best practices, 
intercompany networks and 
exceptional leadership teams.

One of the key ways in which the 
Board can experience and evaluate 
the culture is through meeting with 
colleagues across our businesses. 
We were delighted to have travelled 
to Simonsen & Weel in Denmark and 
Acernis Medical in Canada in April 
2023. The results of our Group 
Colleague Engagement Survey 
(discussed on page 56) have also 
provided further insight.

HOW THE BOARD 
MONITORS CULTURE
The Board
•  Strategy updates

•  CEO’s report

•  Presentations by the  
Group HR Director

•  Sector and function presentations

•  Employee engagement survey

•  Site visits

•  Board Committees

Our Board Committees also play 
an important role in monitoring 
our 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.

•  Audit Committee has oversight of 
internal controls and continuous 
access to 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.

DIPLOMA PLC  ANNUAL REPORT 2023  −  87 

EMPLOYEE ENGAGEMENT
The Board is committed to engaging 
with employees and 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 
two-way 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:

•  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 and engagement 
index score of 80%; the full  
results of the survey are 
detailed on page 56.

DELIVERING VALUE RESPONSIBLY
Our DVR governance structure is lean 
and reflects our decentralised 
model. The Board has ultimate 
oversight and responsibility for DVR 
including DVR governance, strategy, 
performance and climate-related 
risks and opportunities. The Audit 
committee reviews Group climate-
related risks and their mitigation, as 
well as Group TCFD disclosures. The 
Remuneration Committee has a role 
in ensuring flexibility to introduce 
DVR metrics into future remuneration. 

The Executive Team, which includes 
the Sector CEOs, ensures alignment 
and oversight of DVR within their 
areas of responsibility. 

The Senior Leadership Team, 
including Managing Directors, 
is responsible for local DVR 
performance and operational 
execution. They are supported by 
local DVR committees and networks. 

The role of the DVR Steering 
Committee, which includes the 
Group CEO and Sustainability 
Director, is to outline DVR strategy, 
set Group targets, support the 
Sectors and businesses, and monitor 
and communicate progress. 

In a decentralised Group, ensuring 
alignment and driving progress at 
the right pace can be a challenge 
so communication is key. The Board 
is regularly updated on DVR and also 
has an annual in-depth annual 
session with the Group Sustainability 
Director. The SLT and Executive 
Team also cover DVR during regular, 
scheduled updates. All targets and 
metrics are discussed and approved 
by the Board. 

•  Regular updates to the Board at 

OUR DVR GOVERNANCE STRUCTURE 

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.

DEAR SHAREHOLDER 
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. The Committee 
reinforces the Board’s ability to make 
informed decisions and upholds the 
best interests of our shareholders 
and stakeholders.

During the year ended 30 September 
2023, the Committee has ensured 
oversight of all these areas while also 
responding to evolving regulatory and 
market dynamics. Regulatory bodies 
continue to raise the bar on corporate 
governance and financial reporting 
standards. This has necessitated 
an evolution within the business 
environment as we continue to 
adapt and enhance the Committee’s 
oversight functions to maintain the 
highest standards of transparency, 
accountability and integrity in 
our financial reporting and 
governance practices. 

Two key aspects of these reforms 
entail the establishment of the Audit, 
Reporting and Governance Authority 
(ARGA) to oversee audit regulation 
and the anticipated revisions to the UK 
Corporate Governance Code. Other 
aspects of anticipated reforms are 
uncertain following recent government 
statements and we will continue 
to review the evolving landscape. 

The Committee has received reports 
on internal audits for the Group’s 
businesses, together with several 
deep dive sessions, including audits 
of recently acquired businesses, as 
well as updates on the steps being 
taken to address internal audit 
findings and control issues. 

I commented in last year’s report 
that the Committee recognises 
the growing importance of ESG 
factors, including climate-related 
financial disclosures, in shaping the 
investment landscape and promoting 
sustainability. We continue to enhance 
our ESG and climate-related financial 
disclosures, aligning them with best 
practices to provide comprehensive 
and accurate information so that 
stakeholders can make informed 
decisions and effectively assess 
our resilience to climate change.

As Audit Chair, I have 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.

AUDIT COMMITTEE REPORT CONTINUED

After serving on the Board for nearly 
nine years, including in my role as 
Audit Chair, I will be stepping down 
during 2024. It has been a privilege 
to serve alongside my Board 
colleagues and to work with our 
dedicated management team. 
During my tenure, I have witnessed 
the Group’s growth and evolution, 
and I am proud of the progress 
we have made.

I want to express my gratitude to all 
our shareholders for your trust and 
support and I am confident that 
the Group is well-positioned for 
continued success. The Audit 
Committee will transition smoothly 
to a new Chair, who will continue to 
champion the values and principles 
that drive the Group.

I look forward to meeting 
shareholders at the AGM on 
17 January 2024 and will be happy to 
respond to any questions relating to 
the activities of the Audit Committee.

Anne Thorburn
Chair of the Audit Committee 
20 November 2023

PwC has now completed its sixth full 
annual cycle, led by Richard Porter 
who became our lead audit partner 
for this financial year. I am pleased 
to report that again there have been 
no significant control deficiencies 
or accounting irregularities reported 
to the Committee this year. Following 
a routine review of the Company's 
Annual Report by the FRC, the 
Committee became aware that 
approximately £2.5m of the FY21 
interim dividend was not paid in 
accordance with the technical 
requirements of the Companies 
Act 2006. This was because interim 
accounts had not been publicly filed 
prior to the dividend declaration. 
It is intended that this technical issue, 
which has no impact on the Group’s 
financial position, be ratified by a 
shareholders’ resolution proposed 
at the upcoming Annual General 
Meeting (AGM). The Committee has 
reviewed the circumstances and is 
satisfied that the failure was due to 
an inadvertent oversight and is not 
indicative of any wider problem 
with its systems and controls. 
The FRC also highlighted several 
recommendations to improve 
financial reporting which were 
reviewed by the Committee and 
incorporated. 

The Committee plans to commence 
a retender process for the audit 
during 2026/2027 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.

DIPLOMA PLC  ANNUAL REPORT 2023  −  91 

AUDIT COMMITTEE
The Committee is chaired by 
Anne Thorburn 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. Anne 
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 2023 and up to the 
date of this report.

FINANCIAL REPORTING 
AND SIGNIFICANT FINANCIAL 
JUDGEMENTS AND ESTIMATES
The Committee considered 
and assessed:

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 2023. 
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.

ACCOUNTING FOR  
ACQUISITIONS AND DISPOSALS
The Committee reviewed the 
accounting for acquisitions 
completed during the year, in 
particular the acquisitions of DICSA 
and T.I.E.. The acquisitions were 
material for the FY23 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: 

•  the Full Year and Half Year Results, 

a)   the Purchase Price Allocation 

and trading updates for 
recommendation to the Board;

(PPA);

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 
ten smaller acquisitions is 
appropriate. 

The Group completed one disposal 
in the year for proceeds of £25m 
resulting in a net profit on disposal 
of £12m. The profit on disposal has 
been presented within acquisition 
and other related items. 

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. 

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 supply 
chain disruptions 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.

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 appropriateness of accounting 
policies and practices, as well as 
critical accounting estimates and 
key judgements; and

•  whether the Annual Report, 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.

Strategic ReviewCorporate GovernanceFinancial StatementsOther Information92  −  DIPLOMA PLC  ANNUAL REPORT 2023

AUDIT COMMITTEE REPORT CONTINUED

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 equity size 
premium, net of rising 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.

OTHER AUDIT MATTERS
The Committee also considered 
other less material 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 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 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 scenario. 

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 49. Further details on Going 
Concern can be found on page 173.

ENGAGEMENT OF THE 
EXTERNAL AUDITOR
The external auditor is engaged to 
express an opinion on the financial 
statements of the Group and the 
Company. The Committee welcomed 
Richard Porter as the new lead audit 
partner, following last year’s audit 
partner rotation. 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. 

DIPLOMA PLC  ANNUAL REPORT 2023  −  93 

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. 

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.

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 (£74,500). The external 
auditor also provides access to its 
Viewpoint technical subscription 
service (£1,200). 

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 26 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 Internal Control 
and Risk Management on pages  
42 to 48.

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 
above predefined amounts must 
be supported by a paper prepared 
by management.

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. 

Strategic ReviewCorporate GovernanceFinancial StatementsOther Information94  −  DIPLOMA PLC  ANNUAL REPORT 2023

AUDIT COMMITTEE REPORT CONTINUED

The Group Finance department 
continues to develop the 
functionality of this management 
reporting system to provide greater 
insights into the financial and 
operational activities of the 
Group’s businesses.

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.

During the year, management 
reviewed the design of the Minimum 
Controls Framework, encompassing 
a set of standard process controls, 
entity level controls and IT general 
controls that will be rolled out to all 
entities in the Group from FY24, in 
conjunction with the upcoming 
requirements of the UK Corporate 
Governance Reforms. 

The Committee has reviewed the 
effectiveness of the Group’s risk 
management and internal control 
systems for the period from 1 
October 2022 to the date of this 
report. Taking into account the 
matters set out on pages 44 to 48 
relating to principal risks and 
uncertainties and the reports from 
the Group Internal Audit Director, 
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. During the year, 
a new Group Head of Internal Audit 
was appointed, who joined the 
Group in October 2023. Due to the 
expansion of our presence in the US, 
the incumbent Group Internal Audit 
Director will take on a new role and 
be responsible for the internal audits 
of the US entities, reporting to the 
new Group Head of internal Audit. 
This is effective from October 2023, 
with a smooth transition process 
completed at the date of this report. 
The department comprises a Group 
Head of Internal Audit and two 
Group Internal Auditors.

At the beginning of the year, 
the Group Internal Audit Director 
presented the audit plan for the year 
to the Committee for its approval. 
During the year, a risk-based scoping 
process was gradually introduced to 
combine a top-down, strategic 
approach and a bottom-up 
operational approach to identifying 
business risks which, in turn, shape 
the scope of each review when 
carrying out site visits.

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.

The Group Head of Internal Audit 
formally reports to the Committee on 
the results of the internal audit 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 
at least twice a year 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.

The Committee 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.

DIPLOMA PLC  ANNUAL REPORT 2023  −  95 

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, are placed on 
site noticeboards across the Group. 
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/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.

DIPLOMA PLC  ANNUAL REPORT 2023  −  97 

“ Ensuring the right mix of skills and 
experience to deliver long-term 
value for our stakeholders.”

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 FY23 and into FY24, the 
composition of the Board has and 
will continue to change reflecting 
the departures of Anne Thorburn 
and Andy Smith in 2024 after nearly 
nine years of service leading our 
Audit Committee and Remuneration 
Committee respectively.

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, primarily 
the search for the Chairs of the Audit 
and Remuneration Committees to 
ensure these positions are appointed 
in time for an orderly handover. 

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 Company. This 
allows us to identify where further 
focus is needed in the coming years 
and beyond. 

We are mindful of the discussions 
around improving diversity and 
inclusion, together with the targets 
set by the Hampton-Alexander 
Review and the Parker Review. At the 
end of the financial year, three out of 
eight Directors (37.5%) were women 
and we had no Board members from 
a minority ethnic background, 
therefore did not meet the targets 
for women and ethnic minority 
representation.

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 59) 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 diverse 
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 on 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.

NOMINATION COMMITTEE REPORT CONTINUED

NOMINATION COMMITTEE
The Nomination Committee is 
chaired by David Lowden, Board 
Chair. The Committee comprises the 
Non-Executive Directors and meets 
as necessary to discharge its 
responsibilities.

The Group Company Secretary acts 
as Secretary to the Committee.

The Committee reviews the 
composition of the Board and 
principal Committees, considering 
skills, knowledge, experience and 
diversity requirements before making 
appropriate recommendations to the 
Board regarding any changes. It also 
manages succession planning for 
Directors and the Group Company 
Secretary, and oversees succession 
planning for senior leadership across 
the Group.

The Committee’s roles and 
responsibilities are set out in its 
Terms of Reference, which were 
reviewed during the year and 
approved by the Board. 

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 on Life Sciences. 

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.

PROCESS FOR BOARD APPOINTMENTS 
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 & Accounts 
published following the search. 

During the year we engaged 
Korn Ferry in connection with 
the recruitment of Jennifer Ward. 
Korn Ferry do not have any other 
connection to the Group, other 
than providing executive 
search services.

In due course, a tailored induction 
programme is developed for the 
new Director. 

The Committee 
reviews and 
approves an outline 
brief and role 
specification and 
appoints a search 
agent to facilitate 
the search

A Committee 
member discusses 
the specification 
with the 
independent search 
agent, who 
prepares an initial 
longlist of 
candidates

The Committee 
then defines a 
shortlist of 
candidates and we 
hold interviews

The Committee 
makes a 
recommendation to 
the Board for its 
consideration

Following Board 
approval, the 
appointment is 
announced in line 
with the 
requirements of the 
FCA’s Listing Rules

STEP 1STEP 2STEP 3STEP 4STEP 5DIPLOMA PLC  ANNUAL REPORT 2023  −  99 

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 management, 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 Europe. 
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. 

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 2023, 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 
update to the Board in January 2023. 

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.

NOMINATION COMMITTEE REPORT CONTINUED

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 2023 (being the 
reference date selected by the Board 
for the purposes of this disclosure) 
the Company has not fully complied 
with the gender diversity targets of 
Listing Rule 9.8.6R(9) and the  
FTSE Women Leaders Review. 
It is anticipated that following the 
departures of two Non-Executive 
Directors in 2024, the Company will 
fully comply with the gender diversity 
targets of the Listing Rule.

The Committee notes the Parker 
Review and the ethnicity diversity 
targets of Listing Rule 9.8.6R(9) and 
acknowledges 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 2023 the 
Company did not meet the Listing 
Rule 9.8.6R(9) ethnicity target for 
Board members of at least one 
individual on its Board from a 
minority ethnic background.

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 2023, the evaluation 
of the Board as a whole and of its 
committees was undertaken 
internally, led by the Board Chair. 
Board members completed 

questionnaires regarding the 
operation and effectiveness of the 
Board and its Committees. Findings 
were collated by the Group Company 
Secretary and the Board Chair 
discussed the conclusions and 
recommendations separately 
with each Director.

The performance of the Non-
Executive Directors and Executive 
Directors were reviewed by the 

Board Chair. The results of the 2023 
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. Directors 
operated in an atmosphere of open 
and constructive debate with a good 
breadth of skills, experience, and 
viewpoints. Following the evaluation, 
the below recommendations 
were made:

RECOMMENDATION

ACTION

Board and Committee structures

Enhanced risk management

Stakeholders

Review Committee structures and Board schedule to 
reflect the increased size/complexity of the Group, and to 
permit Committees to function in parallel as appropriate.

Development of risk management and an increased 
focus on climate-related and emerging risks, in line with 
our overall strategy.

Develop further understanding of key stakeholders, 
including customers, during Board business visits and 
with additional deep-dive sessions as appropriate.

The Company expects to update shareholders on the progress made in relation to the matters identified above 
in its 2024 Annual Report. 

KEY AREAS FOR DEVELOPMENT
The below recommendations were made following the 2022 external Board performance evaluation.

RECOMMENDATION

ACTION

Consider the diversity of the Board, from both a 
gender and ethnicity standpoint. 

Continue to challenge and support on the progress 
of DVR actions.

Nomination Committee addressed diversity requirements 
in succession planning and during the Non-Executive 
Director recruitment process.

The Board continues to critically review DVR progress and 
actions. After consideration the Board concluded that 
it was preferable for DVR matters to remain the focus 
of the full Board rather than a committee. 

Improve information shared with the Board to 
enhance visibility on certain topics and improve 
decision-making.

Board papers continue to evolve to ensure they 
communicate effectively and facilitate critical 
thinking and decision-making.

“ Another strong year of performance 
adds to the track record of growth, 
strategic execution and strong returns.  
We continue to develop our reward 
based on the interests of all 
stakeholders.”

DEAR SHAREHOLDER 
As Chair of the Board Remuneration 
Committee (Committee), I am 
pleased to present our Directors’ 
Remuneration Report (DRR) for the 
year ended 30 September 2023.

CONTEXT AND APPROACH 
TO REMUNERATION
The Company continues to perform 
very strongly. Our current leadership 
team has led substantial and rapid 
growth and created considerable 
shareholder value over the longer 
term. In September 2018 Diploma 
was ranked 189th on the FTSE index 
and in August 2023 we entered the 
FTSE 100, more than doubling the 
market capitalisation in five years. 

The Board is very pleased with this 
growth and recognises it is key for us 
to retain our strong leadership team, 
incentivise them to deliver and to be 
able attract the talent we need to 
continue to grow. As we continue 
to build high-quality scalable 
businesses that deliver sustainable 
organic growth, our leadership 
roles become bigger and more 
complex. The Committee devotes 
considerable time to ensuring 
that our remuneration policies 
and practices align to strategy 
and that reward is linked firmly to 
performance. The Committee pays 
particular attention to developing 
reward to keep pace with the rapid 
growth in the Company and the 
increasing complexity it brings. 

If the growth trajectory of the 
Company continues, it is likely that 
the organisation will need to bring 
forward the Remuneration Policy 
review for consultation during 2024 
and for voting at the January 2025 
AGM. The Committee will continue to 
review this over the coming months. 

2023 PERFORMANCE PAY 
The leadership team has delivered 
another year of strong performance 
and continued to build on their 
impressive track record (pages  
106 to 107). It has been a year of 
excellent progress with regard to 
scaling the Company to enable 
further growth through building 
infrastructure, developing talent  
and further developing our 
businesses’ target operating  
models, capabilities and cultures. 
Organic growth has been strong, 
driven by revenue diversification 
initiatives and good organic 
performance from recent 
acquisitions. We have continued  
our programme of high-quality 
acquisitions with two strategic 
additions and ten smaller ‘bolt-ons’ 
taking us into new strategic markets 
(further detail on strategic delivery 
can be found on pages 12 to 17). 

Adjusted operating profit, reported 
revenue and free cash all exceeded 
annual bonus targets (on page 109), 
resulting in a full bonus payment 
of 125% of salary for both Johnny 
Thomson and Chris Davies. 

Our long-term performance 
continues to generate excellent 
shareholder returns. 

Our three-year compound annual 
growth rate (CAGR) for adjusted 
earnings per share (EPS) is 31%, 
exceeding the performance target 
maximum of 14%. Return on adjusted 
trading capital employed (ROATCE), 
which underpins our Performance 
Share Plan (PSP), is 18% and in line 
with the Group’s financial model and 
Board expectation. Our three-year 
total shareholder return (TSR) 
performance is in the 88th percentile 
when compared to the comparator 
group of FTSE 250 companies 
(excluding investment trusts). The 
Committee reviewed the possible 
impact of Covid on the outturn of the 
2020 grant and was satisfied that 
there was no windfall gain. Therefore, 
based on these excellent results, the 
PSP 2020 has vested at maximum for 
Johnny Thomson and all other PSP 
participants. Given his start date of 
November 2022, Chris Davies does 
not have any PSP vesting this year.  
Full details are shown in the table 
on page 112. As covered in previous 
disclosures, Chris Davies received 
remuneration to replace variable 
awards foregone at his previous 
employer in order to join the 
Group (shown on page 108).

In line with the Code, the 
Committee reviewed individual 
Directors’ incentive plan outcomes 
and overall remuneration considering 
the Company's underlying 
performance and concluded that 
Executive Director remuneration 
in respect of the year ended 
30 September 2023 is consistent 
with the levels of Company 
performance delivered and that 
there was no requirement for any 
discretionary adjustments.

REMUNERATION COMMITTEE REPORT CONTINUED

IMPACT OF GROWTH AND 
SCALE ON REMUNERATION 
Diploma’s trajectory over the last 
five years is extremely positive 
and has generated excellent 
returns for shareholders. 

On page 107 we have set out 
the journey of growth, portfolio 
development and strategic execution 
delivered by management over the 
last five years since Johnny Thomson 
was appointed as CEO. In that time 
the business has added seven 
new business lines and diversified 
product ranges as well as expanded 
and entered new geographic 
end-markets. 

Balancing the development of 
reward to account for the pace of 
growth and increasing complexity 
and proven, sustainable performance 
is key. Accordingly, the Committee 
pays careful attention to ensuring 
reward follows performance and 
does not precede it. In its 
considerations, the Committee 
balances the interests of 
shareholders, management and 
colleagues, and uses relevant market 
data as context to inform decisions. 
Given our entry into the FTSE 100, 
the Committee now reviews market 
data for companies of a similar 
size using FTSE 51-100 (excluding 
investment trusts and financial 
services) as the broad comparator 
group and a bespoke group of 
11 companies* as a peer comparator. 

REMUNERATION IN 
THE WORKFORCE
Our colleagues are at the heart of 
our success and retaining top talent 
in highly competitive international 
markets is key to Diploma’s delivery. 
We seek to ensure that colleagues 
are fairly and well-rewarded and are 
pleased to note that the Company 
achieved outstanding levels of 
colleague engagement again this 
year (more information on page 56). 

The Committee takes colleagues’ 
perspectives into account when 
considering remuneration across 
the Company. During 2023, the 
Committee engaged with colleagues 
in our workforce via the Executive 
team, business presentations and 
site visits. The general feedback from  
the workforce is that they want the 
Company to be successful and 
sustainable so as to provide job 
security, and for everyone to be 
paid fairly. 

In our decentralised model, 
remuneration decisions for our 
workforce of around 3,300 
colleagues operating in different 
markets, businesses and countries 
are made locally, based on local 
market conditions. We do seek to 
align remuneration throughout the 
Company, and the Group provides 
guidance and oversight to ensure 
we pay all our colleagues fairly and in 
line with our Group reward philosophy. 

For our business leaders, we have 
increased variable pay, both short-
term and long-term remuneration, 
ensuring emphasis on sustainable 
long-term performance. 

The overall workforce pay increase 
for the start of 2024 is 5%. This year 
we have experienced more regional 
variation than usual, driven by 
differences in the pace of changing 
inflation and macroeconomic 
conditions in different markets. 

For our wider workforce, our UK 
businesses are moving towards the 
real living wage (with our businesses 
already accredited or in the process 
of being accredited and new 
acquisitions tasked to move 
towards that goal). We have also 
introduced life assurance for all UK 
colleagues who did not previously 
have it and have introduced further 
healthcare plans. 

EXECUTIVE REMUNERATION 
FOR 2024 – IMPLEMENTATION 
Fixed Pay:
Johnny Thomson continues to deliver 
excellent leadership and build an 
impressive track record. The breadth 
and complexity of his role has 
increased significantly as the 
Company scales and expands into 
new end markets, new products and 
new geographies. 

As stated earlier, our ambition is 
strong, and we want to retain Johnny 
to lead the Company through the next 
phase of growth. He is of great value 
to our business, with a skillset that is 
highly sought after in the market. We 
wish to continue to move his reward 
and incentivisation forward to 
recognise the increased scale of the 
business, the excellent performance 
delivery, and the increased worth in 
the marketplace that his track-record 
of delivery brings. 

Against the current FTSE comparator 
group and also against the bespoke 
peer group*, Johnny’s total direct 
compensation (TDC) is between 
lower quartile and median; base 
rate is at lower quartile and bonus 
as a percentage of salary is below 
lower quartile.

After careful consideration of pace 
of growth, complexity and the 
interests of stakeholders, including 
consultation with ca. 20 of our 
largest shareholders representing 
around 60% of our register, as well as 
the key proxy agencies, the 
Committee has decided to increase 
the CEO's reward this year as 
permitted within our existing policy. 
We are therefore increasing Johnny 
Thomson’s annual base salary from 
£754,000 per annum to £820,000 
per annum, an increase of 8.75%.

NON-EXECUTIVE DIRECTORS 
AND COMMITTEE EVALUATION
The Committee’s performance was 
assessed as part of the annual Board 
evaluation. I am pleased to report 
that the Committee is operating 
effectively. As set out in the 
Nomination Report on page 96 
Jennifer Ward will take up the role 
of Remuneration Chair in June 2024 
after my tenure expires. Jennifer will 
continue our journey on remuneration 
with ongoing partnership with 
shareholders. 

Non-Executive Director fees have 
been reviewed and the increases 
are set out on page 112. The Board 
and Committee are conscious of 
potentially higher demands on 
Non-Executive Directors which may 
arise from the Company’s promotion 
to the FTSE 100. We plan to review 
fees at the end of 2024 based on 
our performance during next year.

CONCLUSION
In closing, I would once again like 
to thank shareholders for their 
engagement over this last year and 
indeed for working closely with me 
over the past nine years. We will 
maintain close dialogue as we 
continue to deliver a competitive, 
motivating pay framework that is 
tightly aligned to shareholder 
experience. We look forward to 
receiving your support at the 
AGM on 17 January 2024.

Andy Smith
Chair of the Remuneration 
Committee
20 November 2023

PSP measures remain unchanged for 
the 2023 grant. 75% of the total 
award will be based on adjusted EPS 
growth, with an underpin on ROATCE.  
25% of the total award will be based 
on relative TSR. Given the Company’s 
promotion into the FTSE 100, it was 
decided that the FTSE 250 (minus 
investment trusts) was no longer the 
best comparator group and having 
considered options, the Committee 
chose the FTSE 100 (minus 
investment trusts) as the most 
appropriate comparator group 
for the 2023 award.

Given the importance of stretching 
targets, the Committee spent time 
reviewing the long-term business 
case. In setting targets, we ensure 
strong focus on organic growth, 
enhanced by quality, strategic 
acquisitions and maintaining financial 
discipline in line with the Company’s 
financial model. The targets for 
adjusted EPS have been set at the 
same level as 2022 (5% threshold 
and 13% maximum). This provides the 
right degree of stretch ambition for 
Diploma at this time. The Board will 
maintain oversight of ROATCE to 
ensure that it meets their 
expectations of high-teens. We will 
continue to review the level of stretch 
annually for each new PSP grant.

ESG
Our ESG programme Delivering Value 
Responsibly (DVR) is now firmly 
embedded in our strategy (more 
detail can be found on page 54).  
The management team are 
accountable for DVR as part of the 
strategy and performance is 
reviewed by the Board. In 2023 we 
set targets for the Group which the 
Committee noted were achieved. 
The Board are continuing to monitor 
performance and we are keeping the 
connection between DVR and 
Executive incentives under review.  
We have flexibility in our policy to 
introduce DVR as a measure in the 
future should that be appropriate.

Chris Davies joined us in November 
2022, and we recruited him on 
a package that reflected that 
of his previous employer and his 
experience at the time. He has made 
a very strong start in his first year 
with us, swiftly establishing himself 
in the role, delivering against all his 
objectives and we are confident 
he will be instrumental in our future 
success. He has led the finance team 
well, building additional capability 
and has played an instrumental role 
in strengthening the Company’s 
finances by managing an equity raise 
to support our M&A pipeline and 
refinancing of the Company’s 
revolving credit facility.

Against the current FTSE market 
group and peer group* CFO TDC is 
below lower quartile as are base rate 
and bonus as a percentage of salary.  
The Committee considered market 
positioning compared to peers, and 
determined that based on the scale 
of his role, his experience, and his 
contribution to the Company, an 
increase to Chris Davies' salary 
is warranted. 

We are therefore increasing 
Chris Davies’ annual base salary from 
£450,000 to £510,000 (an increase 
of 13.3%).  

Annual Bonus:
The 2024 annual performance 
bonus will follow the same measures 
as 2023, namely 50% adjusted 
operating profit, 25% revenue, 25% 
free cash flow. Targets will be based 
on the Board approved budget. 
Maximum bonus for the CEO and 
CFO will remain unchanged at 125% 
of base salary.  

PSP:
Arising from the rationale stated 
above, Chris Davies will receive a PSP 
award of 250% of base salary (PSP 
2022: 200%), which takes him to the 
maximum allowed under the existing 
policy. Additional emphasis on 
long-term reward was supported by 
shareholders and aligns with interests 
in sustainable long-term returns.  
Johnny Thomson will receive a PSP 
award of 300% of base salary which 
remains unchanged from 2022.

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 2023 bonus for Chris Davies will be paid as cash and 50% 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 2024
In the financial year beginning 1 October 2023, the Annual Performance Bonus Plan will be based on the following 
metrics: 50% will be based on adjusted operating profit, 25% will be based on revenue (both metrics measured on 
a constant currency basis) and the remaining 25% will be based on free cash flow. The financial performance targets 
set for the Annual Performance Bonus Plan for this year will be disclosed in next year’s Annual Report & Accounts, 
due to their commercial sensitivity.

ANNUAL REPORT ON REMUNERATION CONTINUED

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  
2023 (PSP 2020), 2024 (PSP 2021), 2025 (PSP 2022) and 2026 (PSP 2023). 

Vesting of the PSP 2020 and PSP 2021 awards are based 50% on growth in adjusted EPS and 50% on relative TSR 
performance. Vesting of the PSP 2022 and PSP 2023 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 28 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)

14% p.a. (PSP 2020) 

13% p.a. (PSP 2022) (PSP 2023)

12% p.a. (PSP 2021)

5% p.a.

Below 5% p.a.

% of awards 
vesting

100

100

Nil

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 28 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 2020, 2021, 
2022 used the FTSE 250 Index (excluding Investment Trusts). PSP award 2023 will use the FTSE 100 Index (excluding 
Investment Trusts) which follows the Company’s promotion to the FTSE 100 Index in August 2023. When analysing the 
impact of moving the relative TSR comparator group from FTSE 250 to FTSE 100, we completed a retrospective 
comparison on PSP 2020, PSP 2019 and PSP 2018 and moving comparator group made no difference to the vesting 
outcome. Hence, the Committee agreed that awards which were granted when the Company was part of the FTSE 
250 would continue to be compared against this index and those granted after promotion would be measured 
against the FTSE 100. The performance targets are as follows:

The PSP award granted on 23 November 2020 (PSP 2020) to Johnny Thomson, was subject to the performance 
conditions as set out on page 110 and independently assessed over a three-year period ended 30 September 2023.

The Committee has reviewed the ROATCE outturn and concluded that 18.1% is in line with expectations. The 
Committee reviewed the topic of windfall gains for the 2020 grant and it determined that as a result of the share 
price increase at the time of grant, there was no windfall gain concern. It was therefore the view of the Committee 
that the formulaic vesting should proceed without any adjustments.

Dividend equivalent payments of £106,895 (2022: £74,881) are payable to Johnny Thomson in respect of the PSP 
(2020) award which vested on 30 September 2023. Dividend equivalent payments cover all payments made in 
the three-year vesting period. 

LONG-TERM INCENTIVE PLAN – AWARDS GRANTED IN THE YEAR (AUDITED)
Johnny Thomson and Chris Davies received a grant of the PSP 2022 award on 18 January 2023 and 28 November 2022 
respectively in the form of nil-cost options. This award was based on a share price of 2,848p and 2,862p respectively, 
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 2022 award for Johnny Thomson was 300% of base salary and for Chris Davies was 
200% of base salary prorated based on his start date of 1 November 2022. Additionally, in line with the Remuneration 
policy, Chris Davies also received grants of the PSP 2021 award on 28 November 2022 in the form of nil-cost options 
to replace variable remuneration awards foregone in order to join the Group. This award was based on a share price of 
2,862p being the mid-market price of an ordinary share in the Company at close of business on the day immediately 
preceding the awards.

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 110. 

OUTSTANDING SHARE-BASED PERFORMANCE AWARDS (AUDITED)
Set out is a summary of the share-based awards outstanding at 30 September 2023, including both share awards

1  The market price is the mid-market share price at the close of business on the day before the grant date as disclosed on page 111.
2  In line with the Remuneration Policy, Chris Davies was granted 7,694 shares as part of the PSP (2021) award to replace share based payment arrangements 

forgone in order to join the Group.

The PSP awards vest on the date on which the performance conditions are determined and confirmed by the 
Committee, following the end of the performance period. Shares will be held for a minimum of five years from 
grant date in line with the Policy. 

The PSP awards are granted in the form of nil-cost options (there is a notional exercise price of £1 per award). 
To the extent that the awards vest, the options are then exercisable until the tenth anniversary of the award date. 
Details of options exercised during the year and outstanding at 30 September 2023 are set out later in this report.

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 2023 and the movements in the number of shares during the 
year are as follows:

less the exercise price of £1.

2   On 22 November 2022, the aggregate number of shares received by the participant was reduced by 40,177 shares as part of arrangements under which the 

company settled the PAYE liability that arose as a result of the exercise in full by the Executive Director of options held over shares. 

3  The closing price of an ordinary share on 30 September 2023 was 3,004p (2022: 2,324p).

The minimum shareholding requirement (MSR) is 300% for the CEO and 250% for the CFO. As of 30 September 
2023, Johnny Thomson’s shareholding was 720% of salary and therefore he has met his MSR. Chris Davies’ 
shareholding was 32% of salary and 50% of his Annual Performance Bonus will be deferred into shares until he 
reaches his MSR as set out in the Policy.

The shareholding calculations are in line with the Company’s Shareholding Policy and includes shares from vested 
PSP awards.

As of 20 November 2023, there have been no changes to these interests in ordinary shares of the Company.

REMUNERATION IN CONTEXT
Chief Executive pay ratio (unaudited)
The table below sets out the Chief Executive pay ratios as at 30 September 2023.

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 2023, 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.

We are satisfied that the median pay ratio reported this year is consistent with our wider pay, reward and progression 
policies for employees. More detail on our approach to workforce pay and alignment to Executive Directors is 
contained on page 121. The CEO is remunerated predominantly on performance-related elements (bonus and share 
awards), which have delivered strong returns. 

The median CEO pay ratio has remained at a similar level to prior year (2023: 126:1; 2022: 129:1). CEO pay has 
increased due to a base pay increase and higher share price appreciation, whilst reducing pension contributions. 
Total compensation for the UK workforce has increased double-digits due to higher wage increases in 2023 and 
higher bonuses. Median total compensation for the UK workforce has increased by 12% and median base pay has 
increased by 9% on prior year. Our UK businesses are moving towards the real living wage (with our businesses 
already accredited or in the process of being accredited and new acquisitions tasked to move towards that goal). 
We have also introduced life assurance for all UK colleagues who did not previously have it and have introduced 
further healthcare plans.

GOVERNANCE
Remuneration Committee
The Committee is chaired by Andy Smith and comprises the six Independent Non-Executive Directors; David Lowden, 
Anne Thorburn, Dean Finch and Geraldine Huse, served on the Committee throughout the year and Jennifer Ward 
was appointed on 1 June 2023. 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 has continued to receive its remuneration advice from Willis Towers Watson (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:

outcome there was no immediate need for shareholder follow up. Consultation was conducted during 2023 on the 
2023 DRR. During consultation there was an opportunity to check with shareholders if they had any outstanding 
issues from 2021 and none were raised.

REMUNERATION POLICY

REMUNERATION POLICY 
This section of the Report sets out our Policy in detail. The current Policy for Executive Directors came into effect 
from 18 January 2023, and remains unchanged. The Policy can be found on pages 120 to 128 of the 2022 Annual 
Report and Accounts, which can be found on our Company website, www.diplomaplc.com, and a summary is set 
out in this Report on pages 118 to 125.

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.

Performance metrics

Salaries are reviewed annually, with 
changes normally effective from  
1 October.

Salary levels and 
increases are 
determined based 
on a number of factors, 
including individual and 
business performance, 
level of experience, 
scope of responsibility, 
salary increases both 
for UK employees and 
for senior management 
more generally and the 
competitiveness of total 
remuneration against 
companies of a similar 
size and complexity. 

No performance metric.

There is no maximum 
limit set. Salaries will be 
market competitive to 
retain skilled executive 
talent and attract new 
talent as required.

Salary increases will 
generally be no higher 
than those awarded 
to other employees, 
although the Committee 
retains discretion to 
award larger increases 
if it considers it 
appropriate.

Maximum pension

2  Stretch is calculated on the same basis as the Maximum bar; however, it includes a share price uplift of 50% over three years for the PSP.

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, and 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. 

Differences in remuneration policy for other employees 
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. 

The Company reviews compensation arrangements including base salaries for the wider employee population 
annually. In line with the Group’s decentralised model, compensation is agreed locally, with governance and guidance 
provided by the Group. 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. 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.

REMUNERATION POLICY CONTINUED

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.

Details of the service contracts of the Executive Directors who served during the year are set out below:

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.

DIPLOMA PLC  ANNUAL REPORT 2023  −  123 

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 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 425% of salary for the CEO and 375% 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 9.4.2 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 of setting 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;

Strategic ReviewCorporate GovernanceFinancial StatementsOther Information124  −  DIPLOMA PLC  ANNUAL REPORT 2023

REMUNERATION POLICY CONTINUED

•  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 120, 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 revised 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.

DIPLOMA PLC  ANNUAL REPORT 2023  −  125 

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.

Our remuneration arrangements for Executive Directors, as well 
as those throughout the organisation, are simple in nature and 
well understood by participants.

Example: variable pay for Executive Directors is a simple Annual 
Bonus Plan and a Performance Share Plan.

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.

The potential value and composition of the Executive Directors’ 
remuneration packages at below threshold, target and 
maximum scenarios are provided in the relevant policy.

Example: variable pay maximums are set out in the 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.

The variable incentive schemes and performance measures 
are designed to be consistent with the Group’s purpose, 
values and strategy.

Example: one of the Diploma values is continuous improvement; 
continuous improvement is required each year to reach 
remuneration targets.

Restrictions on transfer of shares
The Directors may refuse to register a transfer of a 
certificated share that is not fully paid, provided that 
the refusal does not prevent dealings in shares in the

basis, or where the Company has lien over that share. 
The Directors may also refuse to register a transfer of 
a certificated share, unless the instrument of transfer is: 
(i)lodged, duly stamped (if necessary), at the registered 
office of the Company or any other place as the Board 
may decide accompanied by the certificate for the 
share(s), or (ii) in favour of not more than four persons. 
Transfers of uncertificated shares must be carried out 
using CREST and the Directors can refuse to register a 
transfer of an uncertified share in accordance with the 
regulations governing the operation of CREST.

There are no other restrictions on the transfer of ordinary 
shares in the Company except certain restrictions 
which may from time to time be imposed by laws and 
regulations (for example insider trading laws); or where

proportion to their holdings of such equity shares and 
which was not specifically authorised by the Company’s 

shareholders. The details of the allotment are set out 
below in accordance with LR 9.8.4R(7) and the most 
recently published Pre-Emption Group Statement 
of Principles (2022).

Transaction details

In aggregate, equity raised of 9,350,965 New Ordinary Shares (comprising 9,297,005 
Placing Shares, 3,960 Subscription Shares and 50,000 Retail Shares) represented 
approximately 7.5% of the Company's issued ordinary share capital.

Use of proceeds

Settlement for the New Ordinary Shares and Admission took place at 8.00 a.m. 
on 21 March 2023.

The proceeds of the Placing, Subscription and Retail Offer was used to refinance 
the consideration paid for the acquisition of Tennessee Industrial Electronics, LLC, 
a market-leading, value-add distributor of aftermarket parts and repair services into 
the fast-growing US industrial automation end market, with a focus on robotics and 
computer numerical control (CNC) machines, and provide greater flexibility to execute 
further acquisitions.

Quantum of proceeds

In aggregate, the equity raised gross proceeds of approximately £236 million and net 
proceeds of approximately £232 million.

Discount

Allocations

The Placing Price of 2,525 pence represented a discount of 4.2% to the closing share 
price of 2,636 pence on 16 March 2023.

Soft pre-emption has been adhered to in the allocations process. Management was 
involved in the allocations process, which has been carried out in compliance with the 
MiFID II Allocation requirements. Allocations made outside of soft pre-emption were 
preferentially directed towards existing shareholders in excess of their pro rata, and 
wall-crossed accounts.

Consultation

The Joint Bookrunners undertook a pre-launch wall-crossing process, including 
consultation with major shareholders, to the extent reasonably practicable and 
permitted by law.

Retail investors

The equity raise included a Retail Offer, for a total of 50,000 Retail Shares, via the 
PrimaryBid platform.

Retail investors, who participated in the Retail Offer, were able to do so at the same 
Placing Price as all other investors participating in the Placing and Subscription.

The Retail Offer was made available to existing shareholders and new investors in the UK. 
Investors were able to participate through PrimaryBid's platform via its partner network 
(covering 60+ FCA registered intermediaries) and through PrimaryBid's free-to-use 
direct channel. Investors had the ability to participate in this transaction through ISAs 
and SIPPs, as well as General Investment Accounts (GIAs). This combination of 
participation routes meant that, to the extent practicable on the transaction timetable, 
eligible UK retail investors (including certificated retail shareholders) had the opportunity 
to participate in the equity raise alongside institutional investors.

Allocations in the Retail Offer were preferentially directed towards existing shareholders 
in keeping with the principle of soft pre-emption.

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 international accounting 
standards in conformity with the requirements of 
the Companies Act 2006 have been followed for 
the Group financial statements and United Kingdom 
Accounting Standards, comprising FRS 101 have been 
followed for the Parent Company financial statements, 
subject to any material departures disclosed and 
explained in the financial statements;

•  make judgements and accounting estimates that 

are reasonable and prudent; and

•  prepare the financial statements on the going concern 

basis unless it is inappropriate to presume that the 
Group and Parent Company will continue in business.

The Directors are responsible for safeguarding the assets 
of the Group and Parent Company and hence for taking 
reasonable steps for the prevention and detection of 
fraud and other irregularities.

DIRECTORS’ CONFIRMATIONS 
The Directors consider that the Annual Report 
& Accounts, taken as a whole, is fair, balanced and 
understandable and provides the information necessary

prepared in accordance with UK-adopted International 
Accounting Standards in conformity with the relevant 
financial reporting framework;

•  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:

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.

•  so far as the Director is aware, there is no relevant 
audit information of which the Group’s and Parent 
Company’s auditors are unaware; and

•  they have taken all the steps that they ought to have 

taken as a Director in order to make themselves aware 
of any relevant audit information and to establish that 
the Group’s and Parent Company’s auditors are aware 
of that information.

The Directors 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

DIPLOMA PLC  ANNUAL REPORT 2023  −  131 

REPORT ON THE AUDIT OF THE FINANCIAL STATEMENTS

Opinion
In our opinion:

•  Diploma PLC’s Group financial statements and Company financial statements (the “financial statements”) give a true 
and fair view of the state of the Group’s and of the Company’s affairs as at 30 September 2023 and of the Group’s 
profit and the Group’s cash flows for the year then ended;

•  the Group financial statements have been properly prepared in accordance with UK-adopted international 

accounting standards as applied in accordance with the provisions of the Companies Act 2006;

•  the Company financial statements have been properly prepared in accordance with United Kingdom Generally 
Accepted Accounting Practice (United Kingdom Accounting Standards, including FRS 101 “Reduced Disclosure 
Framework”, and applicable law); and

•  the financial statements have been prepared in accordance with the requirements of the Companies Act 2006.

We have audited the financial statements, included within the Annual Report and Accounts (the “Annual Report”), 
which comprise: the Consolidated and Parent Company Statements of Financial Position as at 30 September 2023; 
the Consolidated Income Statement, Consolidated Statement of Comprehensive Income, Consolidated and Parent 
Company Statements of Changes in Equity and the Consolidated Cash Flow Statement for the year then ended; and 
the notes to the financial statements, which include a description of the significant accounting policies.

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 26 to the Consolidated Financial Statements, 
we have provided no non-audit services to the Company or its controlled undertakings in the period under audit.

Our audit approach
Overview
Audit scope
•  The Group is structured as three Sectors (Life Sciences, Seals and Controls) and we have conducted audit 

work across all of them. Through our full scope component audits, audit of the consolidation and additional audit 
procedures performed at a Group level we have achieved coverage of 69% (2022: 74%) of consolidated adjusted 
profit before tax and 68% (2022: 75%) of consolidated revenue.

Key audit matters
•  Valuation of the intangibles for the DICSA and TIE acquisitions (Group)

•  Carrying value of investments in subsidiaries and recoverability of intercompany receivables (Company)

Materiality
•  Overall Group materiality: £10.8m (2022: £6.2m) based on approximately 5% of adjusted profit before tax 

(2022: profit before tax).

•  Overall Company materiality: £6.1m (2022: £3.3m) based on 1% of total assets.

•  Performance materiality: £8.1m (2022: £4.7m) (Group) and £4.6m (2022: £2.5m) (Company).

The scope of our audit
As part of designing our audit, we determined materiality and assessed the risks of material misstatement 
in the financial statements.

Key audit matters
Key audit matters are those matters that, in the auditors’ professional judgement, were of most significance in the 
audit of the financial statements of the current period and include the most significant assessed risks of material 
misstatement (whether or not due to fraud) identified by the auditors, including those which had the greatest effect 
on: the overall audit strategy; the allocation of resources in the audit; and directing the efforts of the engagement 
team. These matters, and any comments we make on the results of our procedures thereon, were addressed in the 
context of our audit of the financial statements as a whole, and in forming our opinion thereon, and we do not provide 
a separate opinion on these matters.

This is not a complete list of all risks identified by our audit.

The key audit matters below are consistent with last year.

Key audit matter

How our audit addressed the key audit matter

Valuation of the intangibles for the DICSA and 
TIE acquisitions (Group)

Refer to page 179 Significant accounting estimates and 
critical judgements (Acquisition accounting) and Note 22 
(Acquisitions and disposals of businesses) within the 
consolidated financial statements.

The Group acquired DICSA and TIE for a combined 
consideration of £234.8m (net of cash acquired). 
Acquired intangible assets of £125.6m 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.

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.

The valuation of the identifiable intangible assets requires 
management estimation as it is dependent on a number 
of key assumptions including forecast revenue growth 
rates, discount rates and average historical customer 
attrition rates. In considering such assumptions, there is 
an inherent level of estimation uncertainty and 
subjectivity.

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:

 β 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.

 β Forecast revenue growth rates and margins: We 

compared the assumptions in respect of forecast 
revenue growth rates and margins to historical 
trading experience and the actual trading 
performance of the businesses post acquisition. 
In addition, we compared the forecasts used in 
the valuations to the Board approved budgets, 
comparable companies and industry reports.

 β 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 are appropriate.

INDEPENDENT AUDITORS’ REPORT TO THE MEMBERS OF DIPLOMA PLC CONTINUEDDIPLOMA PLC  ANNUAL REPORT 2023  −  133 

Key audit matter

How our audit addressed the key audit matter

Carrying value of investments in subsidiaries and 
recoverability of intercompany receivables (Company)

Refer to the Parent Company Statement of Financial 
Position and Note D (“Investments”) within the Company 
financial statements.

At the balance sheet date, the Company had investments 
in subsidiaries of £372.4m (2022: £297.2m) and 
intercompany receivables of £246.9m (2022: £35.8m).

We have focused our audit efforts on this balance given 
the significance of it. The carrying amount of the 
Company’s investments in subsidiaries represents 60% 
of the Company’s total assets (2022: 89%). Given the 
trading performance of the underlying subsidiary 
investments, we do not consider the valuation of these 
investments to be at a high risk of material misstatement 
or to be subject to a significant level of impairment 
judgement/estimation. However, due to their materiality 
in the context of the Company financial statements as a 
whole, it is considered to be the area on which the most 
audit effort is focused within the audit.

In assessing whether the carrying value of the 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 considered whether through 
the work performed throughout the audit identified any 
other impairment indicators regarding the recoverability 
of the carrying value of those investments at 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 reviewed 
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 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 entities which are consolidated by Group management. 

The 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 18 financial reporting components across eight countries for which we determined that full scope 
audits would need to be performed, and one additional component in another country for which we performed audit 
procedures over specific large balances. Through our full scope audits, the audit of the consolidation and other audit 
procedures performed at a Group level, we have achieved coverage of 69% of the Group’s adjusted profit before tax 
and 68% of the Group’s revenue, giving us the evidence we needed for our opinion on the financial statements as a 
whole. The reporting components, excluding those audited by the Group engagement team, were audited by eight 
component teams. 

The Group engagement team attended audit clearance meetings via video conference or in-person, held in-person 
meetings with management from certain UK and USA businesses and discussed the audit approach and audit 
findings with all reporting component teams. Our attendance at each full scope component clearance meeting, 
reviews of the component reporting, and review and discussion of the audit working papers of a number of overseas 
locations, together with the additional procedures performed at Group level, gave us the evidence we needed for our 
opinion on the financial statements as a whole. 

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 Company and four UK components.

Strategic ReviewCorporate GovernanceFinancial StatementsOther Information134  −  DIPLOMA PLC  ANNUAL REPORT 2023

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, TCFD report and the Delivering Value Responsibly section. 

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.

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, 
TCFD report and the Delivering Value Responsibly section within the Annual Report with the financial statements 
and our knowledge from our audit.

Our procedures, which included review of the disclosures made in relation to climate change in the TCFD report by 
our specialists did not identify any material impact in the context of our audit of the financial statements as a whole, 
or our key audit matters for the year ended 30 September 2023. 

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 - Company

Overall materiality

£10.8m (2022: £6.2m).

£6.1m (2022: £3.3m).

How we determined it

Approximately 5% of adjusted profit before 
tax (2022: profit before tax)

1% of total assets

A typical measure used by 
shareholders in assessing the 
performance of a holding company 
and a generally accepted auditing 
benchmark.

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. We changed our benchmark in the 
current year to adjusted profit before tax 
which is a generally accepted auditing 
benchmark given the Group continues to be 
acquisitive in nature and is considered to be 
a more reasonable metric on which to 
measure underlying performance.

INDEPENDENT AUDITORS’ REPORT TO THE MEMBERS OF DIPLOMA PLC CONTINUEDDIPLOMA PLC  ANNUAL REPORT 2023  −  135 

For each component in the scope of our Group audit, we allocated a materiality that is less than our overall Group 
materiality. The range of materiality allocated across components was between £450,000 and £9.9m. 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% 
(2022: 75%) of overall materiality, amounting to £8.1m (2022: £4.7m) for the Group financial statements and £4.6m 
(2022: £2.5m) for the Company financial statements.

In determining the performance materiality, we considered a number of factors - the history of misstatements, risk 
assessment and aggregation risk and the effectiveness of controls - and concluded that an amount at the upper end 
of our normal range was appropriate.

We agreed with the Audit Committee that we would report to them misstatements identified during our audit above 
£537,500 (Group audit) (2022: £312,000) and £305,000 (Company audit) (2022: £165,000) as well as misstatements 
below those amounts that, in our view, warranted reporting for qualitative reasons.

Conclusions relating to going concern
Our evaluation of the directors’ assessment of the Group's and the Company’s ability to continue to adopt the going 
concern basis of accounting included:

•  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 downside and severe but plausible scenarios 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 Company’s ability to 
continue as a going concern for a period of at least twelve months from when the financial statements are authorised 
for issue.

In auditing the financial statements, we have concluded that the directors’ use of the going concern basis 
of accounting in the preparation of the financial statements is appropriate.

However, because not all future events or conditions can be predicted, this conclusion is not a guarantee 
as to the Group's and the Company's ability to continue as a going concern.

In relation to the directors’ reporting on how they have applied the UK Corporate Governance Code, we have nothing 
material to add or draw attention to in relation to the directors’ statement in the financial statements about whether 
the directors considered it appropriate to adopt the going concern basis of accounting.

Our responsibilities and the responsibilities of the directors with respect to going concern are described in the 
relevant sections of this report.

Reporting on other information
The other information comprises all of the information in the Annual Report other than the financial statements and 
our auditors’ report thereon. The directors are responsible for the other information. Our opinion on the financial 
statements does not cover the other information and, accordingly, we do not express an audit opinion or, except 
to the extent otherwise explicitly stated in this report, any form of assurance thereon.

In connection with our audit of the financial statements, our responsibility is to read the other information and, 
in doing so, consider whether the other information is materially inconsistent with the financial statements or our 
knowledge obtained in the audit, or otherwise appears to be materially misstated. If we identify an apparent material 
inconsistency or material misstatement, we are required to perform procedures to conclude whether there is a 
material misstatement of the financial statements or a material misstatement of the other information. If, based on the 
work we have performed, we conclude that there is a material misstatement of this other information, we are required 
to report that fact. We have nothing to report based on these responsibilities.

With respect to the Strategic report and Directors' report, we also considered whether the disclosures required 
by the UK Companies Act 2006 have been included.

Based on our work undertaken in the course of the audit, the Companies Act 2006 requires us also to report 
certain opinions and matters as described below.

Strategic report and Directors' report
In our opinion, based on the work undertaken in the course of the audit, the information given in the Strategic report 
and Directors' report for the year ended 30 September 2023 is consistent with the financial statements and has been 
prepared in accordance with applicable legal requirements.

In light of the knowledge and understanding of the Group and Company and their environment obtained in the 
course of the audit, we did not identify any material misstatements in the Strategic report and Directors' report.

Directors' Remuneration
In our opinion, the part of the Annual Report on Remuneration to be audited has been properly prepared 
in accordance with the Companies Act 2006.

Corporate governance statement
The Listing Rules require us to review the directors’ statements in relation to going concern, longer-term viability and 
that part of the corporate governance statement relating to the Company’s compliance with the provisions of the UK 
Corporate Governance Code specified for our review. Our additional responsibilities with respect to the corporate 
governance statement as other information are described in the Reporting on other information section of this report.

Based on the work undertaken as part of our audit, we have concluded that each of the following elements of the 
corporate governance statement is materially consistent with the financial statements and our knowledge obtained 
during the audit, and we have nothing material to add or draw attention to in relation to:

•  The directors’ confirmation that they have carried out a robust assessment of the emerging and principal risks;

•  The disclosures in the Annual Report that describe those principal risks, what procedures are in place to identify 

emerging risks and an explanation of how these are being managed or mitigated;

•  The directors’ statement in the financial statements about whether they considered it appropriate to adopt the 

going concern basis of accounting in preparing them, and their identification of any material uncertainties to the 
Group’s and Company’s ability to continue to do so over a period of at least twelve months from the date of 
approval of the financial statements;

•  The directors’ explanation as to their assessment of the Group's and Company’s prospects, the period this 

assessment covers and why the period is appropriate; and

•  The directors’ statement as to whether they have a reasonable expectation that the Company will be able to 
continue in operation and meet its liabilities as they fall due over the period of its assessment, including any 
related disclosures drawing attention to any necessary qualifications or assumptions.

INDEPENDENT AUDITORS’ REPORT TO THE MEMBERS OF DIPLOMA PLC CONTINUEDDIPLOMA PLC  ANNUAL REPORT 2023  −  137 

Our review of the directors’ statement regarding the longer-term viability of the Group and Company was 
substantially less in scope than an audit and only consisted of making inquiries and considering the directors’ 
process supporting their statement; checking that the statement is in alignment with the relevant provisions 
of the UK Corporate Governance Code; and considering whether the statement is consistent with the financial 
statements and our knowledge and understanding of the Group and Company and their environment obtained 
in the course of the audit.

In addition, based on the work undertaken as part of our audit, we have concluded that each of the following 
elements of the corporate governance statement is materially consistent with the financial statements and our 
knowledge obtained during the audit:

•  The directors’ statement that they consider the Annual Report, taken as a whole, is fair, balanced and 

understandable, and provides the information necessary for the members to assess the Group’s and Company's 
position, performance, business model and strategy;

•  The section of the Annual Report that describes the review of effectiveness of risk management and internal control 

systems; and

•  The section of the Annual Report describing the work of the Audit Committee.

We have nothing to report in respect of our responsibility to report when the directors’ statement relating to the 
Company’s compliance with the Code does not properly disclose a departure from a relevant provision of the 
Code specified under the Listing Rules for review by the auditors.

Responsibilities for the financial statements and the audit
Responsibilities of the directors for the financial statements
As explained more fully in the Statement of Directors’ responsibilities 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 Company’s 
ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the 
going concern basis of accounting unless the directors either intend to liquidate the Group or the Company or 
to cease operations, or have no realistic alternative but to do so.

Auditors’ responsibilities for the audit of the financial statements
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free 
from material misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinion. 
Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with 
ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and 
are considered material if, individually or in the aggregate, they could reasonably be expected to influence the 
economic decisions of users taken on the basis of these financial statements.

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in 
line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including 
fraud. The extent to which our procedures are capable of detecting irregularities, including fraud, is detailed below.

Strategic ReviewCorporate GovernanceFinancial StatementsOther Information138  −  DIPLOMA PLC  ANNUAL REPORT 2023

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 the 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 Company’s members as a body in 
accordance with Chapter 3 of Part 16 of the Companies Act 2006 and for no other purpose. We do not, in giving 
these opinions, accept or assume responsibility for any other purpose or to any other person to whom this report 
is shown or into whose hands it may come save where expressly agreed by our prior consent in writing.

OTHER REQUIRED REPORTING

Companies Act 2006 exception reporting
Under the Companies Act 2006 we are required to report to you if, in our opinion:

•  we have not obtained all the information and explanations we require for our audit; or

•  adequate accounting records have not been kept by the Company, or returns adequate for our audit have not 

been received from branches not visited by us; or

•  certain disclosures of directors’ remuneration specified by law are not made; or

•  the Company financial statements and the part of the Annual Report on Remuneration to be audited are 

not in agreement with the accounting records and returns.

We have no exceptions to report arising from this responsibility.

Appointment
Following the recommendation of the Audit Committee, we were appointed by the members on 1 March 2018 to audit 
the financial statements for the year ended 30 September 2018 and subsequent financial periods. The period of total 
uninterrupted engagement is six years, covering the years ended 30 September 2018 to 30 September 2023.

OTHER MATTER

In due course, as required by the Financial Conduct Authority Disclosure Guidance and Transparency Rule 4.1.14R, 
these financial statements will form part of the ESEF-prepared annual financial report filed on the National Storage 
Mechanism of the Financial Conduct Authority in accordance with the ESEF Regulatory Technical Standard (‘ESEF 
RTS’). This auditors’ report provides no assurance over whether the annual financial report will be prepared using the 
single electronic format specified in the ESEF RTS.

recognised in cost of inventories sold (2022: £nil) and a £12.2m net gain (2022: £7.3m) on the disposal of 
businesses, which is set out in note 22.

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: Life 
Sciences, Seals and Controls. 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 24 to 35. 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.

Sector assets exclude cash and cash equivalents, deferred tax assets, acquisition related assets and corporate assets 
that cannot be allocated on a reasonable basis to a business Sector. Sector liabilities exclude borrowings (other than 
lease liabilities), retirement benefit obligations, deferred tax liabilities, acquisition liabilities and corporate liabilities 
that cannot be allocated on a reasonable basis to a business Sector. These items are shown collectively in the 
following analysis as “unallocated assets” and “unallocated liabilities”, respectively.

The tax adjustment in the consolidated income statement of £14.7m (2022: £10.9m) 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 blended statutory tax rate for UK corporation tax in respect of the year ended    
30 September 2023 was 22.0% (2022: 19.0%) and this rate has been used for tax on profit in the above reconciliation. 

The Group’s net overseas tax rate is higher than that in the UK, primarily because profits earned in the US, 
Canada, Germany and Australia are taxed at higher rates than the UK. The UK deferred tax assets and liabilities at 
30 September 2023 have been calculated by reference to the UK corporation tax rate of 25.0% (2022: 25.0%).

At 30 September 2023, the Group had outstanding tax liabilities of £16.6m (2022: £11.8m). These amounts are 
expected to be paid within the next financial year.

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. The Group is reviewing the legislation and monitoring the implementation of the rules outside of the 
UK to understand the potential impact. 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 Directors have proposed a final dividend in respect of the current year of 40.0p per share (2022: 38.8p), which 
will be paid on 2 February 2024 subject to approval by shareholders at the Annual General Meeting (AGM) on  
17 January 2024. The total dividend for the current year, subject to approval of the final dividend, will be 56.5p per 
share (2022: 53.8p).

During the year, the Directors became aware that approximately £2.5m of the FY21 interim dividend declared on    
17 May 2021 was paid other than in accordance with the technical requirements of the Companies Act 2006. This 
was because interim accounts had not been filed at Companies House prior to the declaration of the dividend. 
It is intended that this technical issue, which has no impact on the Company's financial position, be ratified by a 
shareholders’ resolution to be proposed at the Annual General Meeting to be held on 17 January 2024. The approach 
that the Company is proposing with regard to this matter is consistent with the approach taken by other UK quoted 
and listed companies that have, similarly, made distributions otherwise than in accordance with the Act. Further 
information can be found in the Parent Company Statement of Changes in Equity on page 181.

The Diploma PLC Employee Benefit Trust holds 67,431 (2022: 71,033) 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 129,675,581 (2022: 124,533,060) and the profit for the year attributable to shareholders 
of £117.7m (2022: £94.7m). Basic earnings per share is 90.8p (2022: 76.1p). Diluted earnings per share is 90.4p 
(2022: 75.9p) and is based on the average number of ordinary shares (which includes any potentially dilutive shares) 
of 130,260,868 (2022: 124,855,007).

An equity placing was completed in March 2023, resulting in the issuance of 9,350,965 (7.5% increase) of 5p ordinary 
shares at a share price of 2,525 pence per placing share, with corresponding fees of £4.2m.

Further description of the Company’s share capital is set out in note (E) to the Parent Company Financial Statements 
on page 183.

Adjusted earnings per share
Adjusted EPS, which is defined in note 28, is 126.5p (2022: 107.5p).

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: Life 
Sciences; Seals; and Controls. 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 FY24, 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; 
Life Sciences 13.2% (2022: 13.9%), Seals 13.3% (2022: 13.8%) and Controls 13.2% (2022: 13.8%). The equivalent 
post-tax discount rates for FY23 are: Life Sciences 10.0% (2022: 10.4%), Seals 10.1% (2022: 10.3%) and Controls 
10.0% (2022: 10.3%). 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 analysis 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 £208.7m (2022: £184.9m) was

Concentrations of credit risk with respect to trade receivables are very limited, reflecting the Group’s customer base 
being large and diverse. The Group has a history of low levels of losses in respect of trade receivables. Management 
is satisfied that the loss allowance takes into account the historical loss experience and forward-looking expected 
credit losses in line with IFRS 9 (Financial Instruments).

As at 30 September 2023, the Group had £9.8m (2022: £nil) of trade receivables that were covered by credit 
insurance in relation to DICSA.

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 and fixed interest 
rate 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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTSFOR THE YEAR ENDED 30 SEPTEMBER 2023CONTINUEDDIPLOMA PLC  ANNUAL REPORT 2023  −  157 

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.

The Group’s maximum exposure to credit risk was as follows:

203.2

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 48 months ended  
30 September 2023 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. 

On 17 July 2023, the Group entered into a new committed multi-currency revolving credit facility agreement ("RCF") 
with an aggregate principal amount of £555.0m. The RCF is due to expire in July 2028 with an option to extend 
for two further 12-month periods. The RCF replaced the Group’s previous debt facility agreement which as at  
30 September 2022 comprised an RCF with an aggregate principal amount of £359.7m, an amortising term loan for 
an aggregate principal amount of £114.2m ($127.5m), a bullet term loan for an aggregate principal amount of £59.1m 
($66.0m) and a further bullet term loan for an aggregate principal amount of £45.3m. 

Additionally, compliance with bank covenants is monitored regularly and during 2023 all bank covenant tests were 
complied with. The applicable financial covenants are interest cover and leverage, whereby EBITDA must be at least 
4x net finance charges (as defined by the SFA); and the ratio of net debt to EBITDA must not exceed 3.5x.

The Group’s debt facilities are subject to interest at variable rates. During FY22 and FY23, the Group entered into 
interest rate swap contracts with the effect of fixing the interest rate on $200.0m (£163.9m) of debt. The effective 
fixed rate debt was 52% of total debt.

There is no material difference between the book value of these financial liabilities and their undiscounted value 
at each reporting date, nor are they relevant to the Group's reporting.

c) Currency risk
The Group’s principal currency risk comprises translational and transactional risk from its exposure to movements in 
US dollars, Canadian 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, Euro, UK Sterling and Swedish Krona. These forward foreign 
exchange contracts are classified as cash flow hedges and are stated at fair value. The notional value of forward 
contracts as at 30 September 2023 was £68.6m (2022: £35.0m). The net fair value of forward foreign exchange 
contracts used as hedges at 30 September 2023 was £0.1m asset (2022: £1.3m 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 £1.3m debit (2022: 
£0.4m debit). The change in the fair value of cash flow hedges taken to Other Comprehensive Income during the year 
was £0.1m credit (2022: £1.4m credit).

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:

Decrease in adjusted operating profit (at average rates)
US dollar: UK sterling
Canadian dollar: UK sterling
Euro: UK sterling
Decrease in total equity (at spot rates)
US dollar: UK sterling
Canadian dollar: UK sterling
Euro: UK sterling

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 uses interest rate swaps to hedge a proportion of 
the external borrowings. These interest rate swaps are classified as cash flow hedges and are stated at fair value. 
The notional value of interest rate swap contracts as at 30 September 2023 was £163.9m (2022: £89.6m). The net fair 
value of interest rate swap contracts used as hedges at 30 September 2023 was £2.3m asset (2022: £3.1m asset) and 
is included within Trade and other receivables on the balance sheet. The amount removed from Other Comprehensive 
Income as a result of the settlement of interest rate swaps, and taken to the Consolidated Income Statement in 
finance costs during the year was a debit of £2.5m (2022: £nil). The change in the fair value of cash flow hedges 
taken to Other Comprehensive Income during the year was £1.7m credit (2022: £3.1m credit). 

All cash deposits, held in the UK and overseas, are held on a short-term basis at floating rates or overnight rates, 
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. 

An increase of 1% in interest rates would have a ca. £2.4m (2022: £1.4m) 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’) 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. 

Strategic ReviewCorporate GovernanceFinancial StatementsOther Information160  −  DIPLOMA PLC  ANNUAL REPORT 2023

Trade and other receivables/payables
As the receivables/payables have a remaining life of less than one year, the book value is deemed to reflect 
the fair value.

Borrowings
The fair value of the borrowings equate to the book value.

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 (£424.4m), cash funds (£62.4m) and medium-
term bank borrowing facilities (£316.8m). 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.

In order to maintain or adjust the capital structure, the Group may change the amount of dividends paid 
to shareholders, return capital to shareholders, issue new shares or increase bank borrowings.

in  M Seals, 5% in Techsil, 2% in R&G Fluid Power Group and 5% in Pennine Pneumatic Services. 

At 30 September 2023, 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 2023. This led to a remeasurement of the options and the liability 
increased by £1.8m (2022: £1.4m increase) reflecting a revised estimate of the future performance of these 
businesses and in aggregate, £1.8m (2022: £1.4m) has been debited to the Consolidated Income Statement 
in respect of this remeasurement of the liability.

22. ACQUISITIONS AND DISPOSALS OF BUSINESSES
Acquisition of Tennessee Industrial Electronics, LLC 
On 6 March 2023, the Group acquired 100% of the share capital of Tennessee Industrial Electronics, LLC (“T.I.E.”), 
a distributor of aftermarket parts and repair services into the US industrial automation end market. The total 
investment, net of cash acquired was £75.1m ($90.3m).

The provisional fair value of T.I.E.’s net assets acquired excluding acquisition intangibles, related deferred tax and 
cash is £10.8m following fair value adjustments of £1.0m. The principal fair value adjustments relate to a net increase 
in inventory (£0.2m) and provisions held against trade receivables (£0.4m), recognition of previously unrecognised 
liabilities (£0.3m) and write down of property plant and equipment (£0.5m). 

Acquisition expenses of £1.5m have been recognised in respect of this transaction in the financial year.

From the date of acquisition to 30 September 2023, T.I.E. contributed £16.6m to revenue and £4.0m to adjusted 
operating profit. If it had been acquired at the beginning of the financial year, it would have contributed on a pro 
forma basis £28.3m to revenue and £6.9m to adjusted operating profit. However, these amounts should not be 
viewed as indicative of the results that would have occurred if T.I.E. had been completed at the beginning of the year. 

Acquisition of Distribuidora Internacional Carmen, S.A.U.
On 12 July 2023, the Group acquired 100% of the share capital of Distribuidora Internacional Carmen, S.A.U. 
(“DICSA”). DICSA, based in Spain, is engaged in the manufacture and commercialisation of stainless steel fittings 
and in the distribution of hydraulic and pneumatic conductions and components. The total investment, net of cash 
acquired is £159.7m (€186.6m).

The provisional fair value of DICSA’s net assets acquired excluding acquisition intangibles, related deferred tax and 
cash is £45.4m following fair value adjustments of £1.4m. The principal fair value adjustments relate to a net increase 
in provisions held against inventory (£0.2m) and trade receivables (£0.1m), recognition of previously unrecognised 
liabilities (£1.0m) and write down of property plant and equipment (£0.1m).

Acquisition expenses of £2.7m have been recognised in respect of this transaction in the financial year.

From the date of acquisition to 30 September 2023, DICSA contributed £16.5m to revenue and £4.0m to adjusted 
operating profit. If it had been acquired at the beginning of the financial year, it would have contributed on a pro 
forma basis £79.5m to revenue and £19.2m to adjusted operating profit. However, these amounts should not be 
viewed as indicative of the results that would have occurred if DICSA had been completed at the beginning of 
the year. 

Other acquisitions
The Group completed a further ten acquisitions in the year. This comprised the trade and assets of Shrinktek 
Polymers International Limited (“Shrinktek”) (11 January 2023), Eurobond Adhesives Limited (“Eurobond”) (23 March 
2023) and International Technologies Group, LLC (“ITG”) (30 March 2023); 100% of the share capital of Fluid Power 
Services Limited (“FPS”) (3 October 2022), Hedley DMB Limited (“Hedley”) (4 October 2022), Valves Online Limited 
(“Valves Online”) (14 March 2023), Gaskets, Packings & Seals Enterprises, LLC (“GP&S”) (14 April 2023), GM Medical 
Group A/S (“GM Medical”) (11 July 2023), Hex Technology, LLC (“Hex”) (17 July 2023) and Lantech Solutions Limited 
("Lantech") (18 September 2023).

The combined initial consideration for these acquisitions was £23.6m, net of cash acquired of £2.4m. Deferred 
consideration with a fair value of £7.4m is payable based largely on the performance of the businesses in the 
period subsequent to their acquisitions.

Acquisition expenses of £0.9m have been recognised in respect of these transactions in the financial year.

The provisional fair value of the total net assets acquired excluding intangibles, related deferred tax and 
cash is £5.4m.

On 17 July 2023, the Group entered into a new committed multi-currency revolving credit facility agreement ("RCF") 
with an aggregate principal amount of £555.0m. The RCF is due to expire in July 2028 with an option to extend 
for two further 12-month periods. The RCF replaced the Group’s previous debt facility agreement which as at  
30 September 2022 comprised an RCF with an aggregate principal amount of £359.7m, an amortising term loan 
for an aggregate principal amount of £114.2m ($127.5m), a bullet term loan for an aggregate principal amount 
of £59.1m ($66.0m) and a further bullet term loan for an aggregate principal amount of £45.3m.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTSFOR THE YEAR ENDED 30 SEPTEMBER 2023CONTINUED 
DIPLOMA PLC  ANNUAL REPORT 2023  −  165 

The Group’s debt facilities are subject to interest at variable rates. During FY22 and FY23, the Group entered into 
interest rate swap contracts with the effect of fixing the interest rate on $200.0m (£163.9m) of debt. The effective 
fixed rate debt was 52% of total debt.

At 30 September 2023, the Group’s Net Debt/EBITDA ratio is 0.9x, as illustrated in note 28. 

As at 30 September 2023, the Group has utilised £320.9m of the revolving facility. There remains £234.1m undrawn 
on the revolving facility. Borrowings include £0.2m (2022: £1.0m) of accrued interest and the carrying amount of 
capitalised debt fees is £4.3m (2022: £4.7m). 

As at 30 September 2023 the Group's net debt is £254.7m (2022: £328.9m) and excludes lease liabilities of £80.2m 
(2022: £69.1m). 

25. RETIREMENT BENEFIT ASSET 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 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 is a defined contribution based scheme, which for technical reasons, is required under IFRS 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:

Defined contribution schemes operated by the Group’s businesses are not included in these disclosures.

Diploma Holdings PLC UK Pension Scheme
The Scheme is subject to the Statutory Funding Objective under the Pensions Act 2004. A valuation of the Scheme 
is carried out at least once every three years to determine whether the Statutory Funding Objective is met. As part 
of the process the Company must agree with the Trustees of the Scheme the contributions to be paid to meet the 
Statutory Funding Objective. The most recent triennial actuarial valuation carried out as at 30 September 2022 
reported that the Scheme had a funding surplus of £2.2m and held assets which covered 107% of its liabilities at that 
date. The next triennial actuarial valuation of the Scheme will be carried out as at 30 September 2025 and the results 
of the valuation will be reported in the 2026 Annual Report & Accounts. There were no Scheme amendments, 
curtailments or settlements during the year.

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. 
The impact of this transaction has been reflected in the pension disclosures set out below.

Strategic ReviewCorporate GovernanceFinancial StatementsOther Information166  −  DIPLOMA PLC  ANNUAL REPORT 2023

The Scheme is managed by a set of Trustees appointed in part by the Company 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.

The Scheme exposes the Company, and therefore the Group, to a number of risks:

•  Investment risk: The Scheme holds investments in asset classes that have volatile market values and while these 
assets are expected to provide broadly matching real returns over the long term, the short-term volatility can 
cause additional funding to be required if deficits emerge.

•  Interest rate risk: The Scheme’s liabilities are assessed using market yields on high-quality corporate bonds to 
discount the liabilities. As the Scheme is predominantly invested in government bonds, the value of the assets 
is expected to move broadly in the same way as the liabilities.

•  Inflation risk: A significant proportion of the benefits under the Scheme are linked to inflation. Although the 

Scheme’s assets are expected to provide a good hedge against inflation over the long term, movements over 
the short term could lead to funding deficits emerging.

•  Mortality risk: In the event that members live longer than assumed, deficits may emerge in the Scheme.

In addition to the Buy-in policy, the pension scheme holds £1.8m of historic annuity policies. Their inclusion would 
have no impact on the net IAS 19 financial position, as the insurance policy exactly matches the related obligation, and

The increase in the Scheme surplus was due to a combination of a slight rise in corporate bond yields, which has led 
to a higher discount rate and therefore a lower value being placed on the liabilities, and a slight fall in the market’s 
expectation of future inflation, which has also reduced the value placed on the liabilities. The Scheme had 78% 
of its assets in bonds as at 30 September 2023, with no exposure to LDI.

Risk mitigation strategies
When setting the investment strategy for the Scheme, the Trustees, in conjunction with the employer, take into 
account the liability profile of the Scheme. Annuity policies have been taken out in respect of some historic 
pensioners, but the Scheme has not purchased annuities for retirements since 2005. In addition to these individual 
annuity policies, the Trustees have purchased a Buy-In policy for all existing pensioners as at 1 September 2018. The 
Buy-In policy secures the Scheme against both market and mortality risk relating to these pensioners. The Scheme 
however remains liable ultimately for the liabilities, should the insurance company which sold the liabilities go into 
insolvent liquidation. 

In FY23, the Trustees have considered all asset classes and have gained exposure to fixed interest index-linked 
Gilts and bulk annuity. The Trustees consider these assets to reduce the risk of the assets failing to meet the liabilities 
over the long term.

Effect of the Scheme on the Group’s future cash flows
The Company 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, the 
Company agreed to contribute £0.6m in cash to the Scheme annually increasing at 2% per year. The current year 
contribution was £0.6m. No one-off contributions were made in the year (2022: none).

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.

28. ALTERNATIVE PERFORMANCE MEASURES 
The Group reports under International Financial Reporting Standards (IFRS) 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, IFRS 
measures. The definitions of the alternative performance measures and the comparisons to their closest IFRS 
measures can be found on pages 188-189.

28.1 Revenue Growth 
As a multi-national Group of companies who trade in a large number of currencies and also acquire and sometimes 
dispose of companies, organic performance is also referred to throughout the Annual Report. These strip out the 
effects of the movement in exchange rates and of acquisitions and disposals. The Board believe that this allows 
users of the financial statements to gain a better understanding of how the Group has performed. 

A reconciliation of the movement in revenue compared to the prior year is given below.

The Organic revenue growth percentage is the incremental revenue generated under Diploma’s ownership compared 
to the revenue in the same period prior to acquisition, at prior period exchange rates. 

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTSFOR THE YEAR ENDED 30 SEPTEMBER 2023CONTINUED 
DIPLOMA PLC  ANNUAL REPORT 2023  −  171 

The impact of acquisitions on growth is the revenue of the acquiree prior to the acquisition by Diploma for the 
comparable period at prior year exchange rates. The impact of disposals on growth is the removal of the revenue 
of the disposed entity in the comparable post disposal period at prior year exchange rates. The Acquisitions and 
Disposals growth percentage is calculated as the impact of acquisition and disposals divided by the reported 
revenue in the prior period. 

Exchange translation movements are assessed by re-translating current year reported values to prior year 
exchange rates.

28.2 Adjusted operating profit and adjusted operating margin
Adjusted operating profit is the operating profit before adjusting items that would otherwise distort operating profit, 
currently and more recently 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.

A reconciliation between operating profit as reported under IFRS and adjusted operating profit is given below:

28.3 Adjusted earnings per share
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 129,675,581 (2022: 124,533,060), as set out in note 9. The Directors believe that adjusted EPS provides an important 
measure of the earnings capacity of the Group. 

28.4 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 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.

28.5 Leverage
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 facility 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.

28.6 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 re-translated 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.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTSFOR THE YEAR ENDED 30 SEPTEMBER 2023CONTINUEDGROUP ACCOUNTING POLICIES
FOR THE YEAR ENDED 30 SEPTEMBER 2023

DIPLOMA PLC  ANNUAL REPORT 2023  −  173 

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 75. The financial 
position of the Group, its cash flows, liquidity position 
and borrowing facilities are described in the Financial 
Review on pages 36 to 40. In addition, pages 156 to 160 
of the Annual Report & 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 macroeconomic disruption, including widespread 
global inflation, rising interest rates, 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 44 to 48.

Liquidity and financing position
The Group’s liquidity and funding arrangements are 
described in notes 24 and 28 to the consolidated 
financial statements. 

Financial modelling
The Group has modelled a base case and 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 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 enquiries, 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 & 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
There have been no 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.

Strategic ReviewCorporate GovernanceFinancial StatementsOther Information174  −  DIPLOMA PLC  ANNUAL REPORT 2023

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 receivable 
for services supplied to customers, as opposed to 
goods, is ca. 3% 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 balance sheet 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 net deficit of the plan 
– 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 
Monte Carlo 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 Monte Carlo 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.

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 
and deferred tax.

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.

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 financial statements 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 deficit 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.

Strategic ReviewCorporate GovernanceFinancial StatementsOther Information176  −  DIPLOMA PLC  ANNUAL REPORT 2023

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 property

–   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 administration cost.

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.

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.

GROUP ACCOUNTING POLICIESFOR THE YEAR ENDED 30 SEPTEMBER 2023CONTINUED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.

DIPLOMA PLC  ANNUAL REPORT 2023  −  177 

1.13 FINANCIAL INSTRUMENTS
Financial assets and liabilities are recognised in the 
Group balance sheet 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. 
Bank overdrafts (where used) are presented net of cash 
and cash equivalents on the balance sheet, 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. 
The Group has elected to continue to apply the hedge 
accounting requirements of IAS 39, as allowed 
under IFRS 9. 

Strategic ReviewCorporate GovernanceFinancial StatementsOther Information178  −  DIPLOMA PLC  ANNUAL REPORT 2023

Derivatives are initially recognised at fair value on 
the date a derivative contract is entered into and 
subsequent changes in the fair value of foreign 
currency derivatives which are designated and effective 
as hedges of future cash flows are recognised in equity 
in the hedging reserve and in Other Comprehensive 
Income and are reclassified to profit or loss on maturity 
of the derivative. Changes in the fair value of foreign 
currency derivatives which are ineffective or do not 
meet the criteria for hedge accounting in accordance 
with IAS 39 are recognised immediately in the 
Consolidated Income Statement.

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.

No derivative contracts have been designated as fair 
value hedges or net investment 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.

1.16 DIVIDENDS
The annual final dividend is not provided for until 
approved at the AGM; interim dividends are charged 
in the period they are paid.

1.17 SHARE CAPITAL AND RESERVES
Ordinary shares are classified as equity and details of the 
Group’s share capital is disclosed in note (e) 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.

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.

GROUP ACCOUNTING POLICIESFOR THE YEAR ENDED 30 SEPTEMBER 2023CONTINUEDDIPLOMA PLC  ANNUAL REPORT 2023  −  179 

1.20 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.

1.20.1 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 T.I.E. and 
DICSA intangible assets, which were acquired in the year, 
together with the sensitivity analysis, are set out below.

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 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 2023. 

IFRS 17 ‘Insurance contracts’ which is ultimately 
intended to replace IFRS 4, will become effective in the 
consolidated Group financial statements for the financial 
year ending 30 September 2024;

IFRS 16 amendments ‘Lease liability in a sale and 
leaseback’, which will become effective in the 
consolidated Group financial statements for the 
financial year ending 30 September 2025, subject 
to UK endorsement;

IAS 1 - Presentation of Financial Statements - in relation 
to non-current liabilities with covenants and deferral of 
effective date, and the Disclosure of Accounting Policies;

IAS 8 - Accounting Policies in relation to the definition 
of Accounting Estimates;

IAS 12 – Deferred tax related to assets and liabilities 
arising from a single transaction and International tax 
reform – pillar two model rules.

The Group does not anticipate that the adoption of these 
standards and interpretations that are effective for the 
year ending September 2024 will have a material effect 
on its financial statements.

Strategic ReviewCorporate GovernanceFinancial StatementsOther Information180  −  DIPLOMA PLC  ANNUAL REPORT 2023

Management are 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:

1.20.2 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.

1.20.3 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.

1.20.4 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 2023, the Defined benefit pension 
obligation for the UK defined benefit pension scheme is 
an asset rather than an obligation due to the increase in 
bond yields impacting on discount rate and a fall in the 
market’s expectations of future inflation, whilst the Kubo 
defined benefit pension scheme is a net liability. Detail 
of the estimates and key sensitivities made in calculating 
the defined benefit asset at 30 September 2023 are set 
out in note 25 to the consolidated financial statements.

During the year, the Directors became aware that approximately £2.5m of the FY21 interim dividend declared on 
17 May 2021 was paid other than in accordance with the technical requirements of the Companies Act 2006. This 
was because interim accounts had not been filed at Companies house prior to the declaration of the dividend. 
It is intended that this technical issue, which has no impact on the Company's financial position, be ratified by a 
shareholders’ resolution to be proposed at the Annual General Meeting to be held on 17 January 2024. The approach 
that the Company is proposing with regard to this matter is consistent with the approach taken by other UK quoted 
and listed companies that have, similarly, made distributions otherwise than in accordance with the Act.

The Directors will propose a resolution at the Annual General Meeting to be held on 17 January 2024 to authorise the 
appropriation of distributable profits to the payment of the interim dividend and remove the right of the Company to 
pursue shareholders or directors for repayment. The effect of this resolution will be to return all parties to the position 
that they would have been in, had the FY21 interim dividend been made in full compliance with the Companies Act 
2006. As the Directors believe that passing this resolution will be in the best interests of the members, no adjustment 
has been made to the Statement of Changes in Equity presented above.

The Parent Company Financial Statements (the Financial Statements) have been prepared consistently in accordance 
with the Companies Act 2006 and FRS 101 (Reduced Disclosures Framework). The Directors confirm they have a 
reasonable expectation that the Company has adequate resources to continue in operational existence for the 
foreseeable future and accordingly, they continue to adopt the going concern basis in preparing the Financial 
Statements. The Financial Statements, which are prepared on a historical cost basis, are presented in UK 
sterling and all values are rounded to the nearest 100,000 except when otherwise indicated.

Diploma PLC is a public company limited by shares incorporated in the United Kingdom, and registered and

ALTERNATIVE PERFORMANCE MEASURES

MEASURE

Organic growth

CLOSEST IFRS 
MEASURE

Reported revenue 
increase 

Adjusted operating 
profit

Operating profit

DEFINITION AND RECONCILIATION

PURPOSE

Organic growth strips out the effects 
of the movement in exchange rates 
and of acquisitions and disposals.

Statutory operating profit excluding 
separately disclosed items and 
can be found on the face of the 
Group Income Statement in the 
Adjusted column.

Allows users of the financial statements 
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 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 year-on-year trading performance of 
the Group.

Adjusted operating 
margin 

Operating profit 
divided by revenue

Adjusted operating profit divided 
by revenue.

Adjusted operating margin is a measure 
used to assess and compare profitability.

Return on adjusted 
total capital employed 
("ROATCE")

Operating profit and

Free cash flow

Net cash generated 
from operating 
activities

Net debt

Borrowings less cash 

It also allows for ongoing trends and 
performance of the Group to be 
measured by the Directors, management 
and interested stakeholders.

Adjusted earnings per share is widely 
used by external stakeholders, 
particularly in the investment community.

ROATCE gives an indication of the 
Group’s capital efficiency and is an 
element of a performance measure for 
the Executive Directors’ remuneration.

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 is the measure by which the 
Group and interested stakeholders 
assesses its level of overall indebtedness.

Adjusted earnings (being adjusted 
profit after tax attributable to equity 
shareholders) for the period 
attributable to shareholders of the 
Company divided by the weighted 
average number of shares in issue, 
excluding those held in the Employee 
benefit trust which are treated as 
cancelled. 

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 for the reporting period.

The cash flow equivalent of adjusted 
profit after tax.

Cash and cash equivalents (cash 
overnight deposits, other short-term 
deposits) offset by borrowings which 
compose of bank loans, excluding 
lease liabilities.

CLOSEST IFRS 
MEASURE

Operating profit

MEASURE

Earnings Before 
Interest and Tax plus 
Depreciation and 
Amortisation (“EBITDA”)

Leverage

No direct equivalent

DEFINITION AND RECONCILIATION

PURPOSE

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.

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.

EBITDA is calculated by taking 
adjusted operating profit and adding 
back depreciation and amortisation.

The ratio of net debt to EBITDA over 
the last 12 months, after making the 
following adjustments to EBITDA: 
including any annualised EBITDA for 
businesses acquired by the Group 
during that period; the reversal of IFRS 
16 accounting; the exclusion of any 
EBITDA businesses disposed by the 
Group during that period; and the 
exclusion of the profit or loss 
attributable to minority interest.
