Overview
2024 further demonstrated Senior’s resilience, 
once again having to navigate through choppy 
waters given external events. As a consequence 
of the well-documented situation at Boeing, 
impacting production volumes, we had to revise 
expectations to the market. The team delivered 
trading in line with revised market expectations 
and a strong cash performance. They responded 
by dynamically, supporting our customers and 
controlling our costs, to limit the impact on 
Aerospace profitability in 2024. Our robust 
strategy and product offerings in attractive 
end markets, combined with the focused and 
disciplined operational and pricing management, 
enabled us to emerge strong overall. 
Our core markets developed largely as expected 
throughout the year. Boeing sales were 
impacted by 737 MAX volumes being subdued 
following the Alaska Airlines incident in January 
and from their employee strike from September 
to November leading to a shutdown of 737 
MAX, 767 and 777 production.
Timely actions were taken to minimise cost and 
balance sheet exposure. Senior focused on 
operational efficiency during the year and 
maintained diligence on pricing and making sure 
commercial terms were reflective of current day 
pricing. Due to specific actions implemented 
both by us and our suppliers, Senior’s supply 
chain has become more stable. A few hotspots 
remain, and we are continuing to work with our 
customers and suppliers to resolve these. We 
are also closely monitoring the impact on global 
trade from potential tariff changes.
The operating businesses as a result delivered 
improved profitability during the period. 
The Group’s revenue growth was 4% on 
a constant currency basis and a healthy 
book-to-bill of 1.12 underpins future growth. 
A massive thank you to David, Bindi and all 
of our teams for the 2024 results. 
Strategy
Senior is committed to a sale of our 
Aerostructures business and is making good 
progress with this process. This is in line with 
our strategy to position Senior as the market 
leading pure play fluid conveyance and thermal 
management business. 
The Group has a solid foundation to support 
future growth aspirations. We have well 
equipped businesses and are supported by 
extensive design and manufacturing process 
intellectual property and know-how. Our offering 
is pivotal technologies for emissions reduction 
and environmental efficiency; capabilities that 
continue to be highly relevant as the world 
transitions towards a lower carbon economy. 
With continued R&D investment in these 
technologies and by leveraging our engineering 
capabilities, we will ensure that we provide 
solutions over the long term for our customers. 
A good example is the standards-compliant 
parts strategy which taps into the high-growth, 
high-pressure hydraulic fluid fittings space 
enabled by our 2022 acquisition, Spencer 
Aerospace. The collaboration between Spencer 
and Senior Aerospace in France continues to 
progress well with innovative new products 
being designed for Commercial Aerospace. 
In order to showcase our fluid conveyance 
and thermal management capabilities, the 
Company in June hosted an investor site visit 
to our Senior Aerospace France businesses 
(Ermeto and Calorstat). This engagement 
enabled us to demonstrate how such products 
will shape the growth of our business over the 
short and medium term. 
As a well-capitalised and intrinsically cash 
generative Group, our operating businesses 
have existing capacity to benefit from our 
attractive end markets. Complementing this is 
the Group’s strong financial position and robust 
balance sheet, further enhanced by the issuance 
of a $40m private placement in February 2025. 
The Board actively reviews the Group’s portfolio, 
ensuring a considered and effective capital 
deployment to maximise shareholder value 
creation. As the Group advances in its strategy, 
growing Senior’s high-quality fluid conveyance 
and thermal management businesses becomes 
the focus. Underpinning this will be investments 
supported by a business case and assessed 
using a rigorous investment appraisal process.
The Board is confident in the Group’s strategy 
and that it will deliver enhanced value for 
all our stakeholders.

STRATEGIC  
REPORT

Our performance and dividend
In 2024, the Board and the Executive team 
continued to make good strategic, operational, 
and financial progress. Senior delivered trading 
in line with revised expectations, a strong cash 
performance, and grew the order book.
Group revenue increased 4% (on a constant 
currency basis) to £977.1m. Our adjusted 
operating profit increased to £46.5m which 
resulted in the Group’s adjusted operating 
margin increasing by 10 basis points (on a 
constant currency basis), to 4.8%. 
The Group has a healthy balance sheet and 
period-end net debt to EBITDA of 1.8x, after 
taking into account a £15.0m payment for 
dividends and net purchase of shares, and 
£10.7m contingent consideration for the 
acquisition of Spencer Aerospace following its 
strong growth post-acquisition.
The Board has confidence in the Group’s 
performance, financial position and future 
prospects, and is proposing a final dividend 
of 1.65 pence per share. This would bring total 
dividends, paid and proposed for 2024 to 2.40 
pence per share, an increase of 4% over 2023. 
The Board will continue to follow a progressive 
dividend policy reflecting earnings per share, 
free cash flow generation, market conditions 
and dividend cover over the medium term. 
Our sector leading 
sustainability credentials 
The Board acknowledges the critical importance 
of implementing a bold and comprehensive 
sustainability programme. We firmly believe 
that our Company Purpose and leadership 
in sustainability provide a unique commercial 
advantage as the global economy transitions 
to a lower carbon future. Sustainability is deeply 
embedded in our strategy, reflected in the 
behaviours of our people and the culture 
of our organisation.
In 2024, we reached several significant 
milestones in our sustainability journey including 
being awarded the top ‘A’ score by CDP in its 
global annual ranking for transparency on climate 
change for 2024, reducing our Scope 1 and 2 
emissions by 33% against our 2018 baseline 
and meeting our Near-Term Science-Based 
Target ahead of the 2025 target.
Looking ahead to 2025, we are committed to 
building on this strong foundation by enhancing 
our sustainability programmes and reporting. 
Our focus will be on addressing both financial 
and environmental/social impacts, ensuring our 
leadership in sustainability continues to deliver 
long-term value for all stakeholders.
The Sustainability Report on pages 12 to 17 
provides more detail on how we are progressing.
Our Board 
In 2024, the Board maintained its focus on 
succession planning. Following Bindi Foyle’s 
announcement to retire from a full-time Executive 
career, and after a thorough recruitment process, 
we appointed Alpna Amar as the Group Chief 
Financial Officer. We welcome Alpna to Senior’s 
Board in April 2025, and we are confident that her 
strong financial acumen and expertise will be well 
placed to drive Senior’s financial strategy to the 
next stage of growth. The Board would like to 
thank Bindi for her outstanding contribution to 
Senior over the past 19 years, and we wish her 
well for the future.
After nine years as a non-executive Director, 
Susan Brennan will be retiring following the 
conclusion of the Company’s AGM in April 
2025. I would like to take this opportunity to 
thank Susan for her valued contribution and 
commitment over the last nine years. As 
announced earlier in 2024, Zoe Clements joined 
the Board as an independent non-executive 
Director with effect from 1 September 2024. 
We believe that Zoe’s strengths as an 
investment, private equity and financial 
professional will complement the Board’s 
expertise and decision-making.
I am confident that the Board continues to have 
the right balance of skills and capabilities to 
provide effective oversight over the Company’s 
future strategic journey.
Further information can be found in the 
Governance section of the Report on page 70.
Stakeholder Engagement
The Board has a strong responsibility to all of 
Senior’s stakeholder groups – our shareholders, 
employees, customers, suppliers and the 
communities we operate in. We believe that 
engaging with our stakeholders is key to the 
long-term success of the Group. 
In 2024, the Executive team, Group Chair, and 
Chair of the Remuneration Committee (Barbara 
Jeremiah), continued the Group’s engagements 
with shareholders across multiple channels. 
This included writing to shareholders regarding 
potential changes to the Remuneration Policy 
and the LTIP rules. Please refer to page 97 in the 
Remuneration Report. 
This year the Group has conducted its third 
global Employee Opinion survey. 85% of our 
employees completed the survey which is an 
excellent result considering that approximately 
only 40% of our employees have ready access 
to business emails. 
Mary Waldner, the non-executive Director for 
employee engagement and Jane Johnston, 
Group HR Director have continued their 
programme of face-to-face focus groups. 
In addition, Mary has met delegates from 
our Leading for Excellence group development 
programme, met leadership teams when 
visiting sites and joined the monthly global 
HR calls in June. 
Looking forward
Senior is delivering in line with our strategy, 
upholding our focus on highly engineered, 
IP-rich, fluid conveyance and thermal 
management expertise and capabilities. 
Looking ahead, we are positioning Senior 
as a pure play fluid conveyance and thermal 
management business operating in attractive 
and structurally resilient core markets. This 
position combined with our sector-leading 
sustainability credentials and highly-relevant 
technical capabilities, underpins our commitment 
to deliver a strong performance across our 
both Divisions. Reflecting the Board’s 
confidence, we have announced new and 
improved medium term financial targets for 
the fluid conveyance and thermal management 
business, which will deliver consistent value 
creation for all of our stakeholders.
Good strategic, operational, and financial 
progress has been made in 2024 and we remain 
confident of continuing to do so in 2025. 
On behalf of the Board, I would like to thank our 
employees and all other stakeholders for their 
continued support and commitments.

Overview of 2024 results
Senior delivered 2024 results in line with 
revised expectations, enhanced by a strong 
cash performance. 
A book-to-bill ratio of 1.12 reflected strong order 
intake in 2024, underpinning the Group’s 
confidence in continued growth in 2025 and 
beyond. Both our divisions recorded good order 
intake, with some notable contract wins 
including from Safran, Deutsche Aircraft 
GmbH, Gail India Limited and land vehicle 
OEMs (details in the divisional reviews below), 
showcasing the broad, diversified and 
high-quality nature of our business.
During 2024, Group revenue increased by 4% 
on a constant currency basis to £977.1m, with 
growth in the Aerospace Division and lower 
sales in the Flexonics Division as expected. 
Exchange rates had an adverse impact of 
£25.5m to total sales.
In Aerospace, revenue increased 10% year-on-
year on a constant currency basis. The increase 
reflected improved pricing, the ramp up in civil 
aircraft production rates and very strong growth 
of over 50% in Spencer Aerospace. This was 
despite 737 MAX volumes being subdued 
throughout the year following the Alaska 
Airlines incident in January 2024 and the Boeing 
employee strike from September to November 
2024. We saw a return to growth in sales to 
semiconductor equipment customers (which is 
included in “Adjacent Markets”) and steady 
growth in the defence market. In Flexonics, 
revenue was in line with expectations, down 
Airlines incident in early 2024 and 3 months of 
lost production on 737 MAX, 767 and 777 due 
to the strike at its factories in The Puget Sound. 
Boeing have now started to ramp up production 
following the recommencement of operations in 
December 2024.
Senior responded to these events dynamically, 
supporting our customers and controlling 
our costs. Nonetheless, these temporary 
headwinds did affect Aerospace profitability 
in 2024.
Flexonics followed a more predictable path, 
with Senior outperforming anticipated softer 
end markets in 2024.
The Group generated free cash flow of £17.3m 
(2023 – £15.5m) in 2024. The improvement 
from 2023 was a result of lower working capital 
outflows more than offsetting higher investment 
in capital expenditure and higher tax and interest 
payments. Cash outflows from working capital 
were £17.0m (2023 – £27.6m outflows), 
reflecting increased inventory, offset partially 
by inflows from receivables and payables. 
Inventory was higher in Aerospace with planned 
investment to enable us to meet the increase 
in demand from our customers, and as a result 
of the impact of the Boeing strike and certain 
customer schedule changes in Q4. Gross capital 
expenditure was £43.2m (2023 – £35.9m) 
which was 1.1x depreciation (excluding the 
impact of IFRS 16). 
6% compared to prior year, on a constant 
currency basis. The Group saw robust demand 
in our downstream oil and gas and nuclear 
business, partially offsetting a reduction in sales 
from one of our operating businesses to our 
upstream oil and gas customers due to a lower 
share of this very competitive market sector. 
Global land vehicle markets softened as 
expected in 2024, however, our sales 
outperformed key end markets due to the ramp 
up of recently won production contracts.
We measure Group performance on an adjusted 
basis, which excludes items that do not directly 
reflect the underlying trading performance in the 
period (see Note 9). References below therefore 
focus on these adjusted measures.
The Group’s adjusted operating profit increased 
by 5% on a constant currency basis to £46.5m 
driven by improved profit in Aerospace more 
than offsetting the expected volume-related 
reduction in profit in Flexonics. Adjusted 
operating margin increased by 10 basis points 
in 2024 to 4.8%. 
The market backdrop for our Aerospace Division 
remains healthy with order books for large 
commercial aircraft at record levels, driven by 
increasing air passenger demand. There were 
some supply chain issues for Airbus and its 
suppliers through the year, and although there 
are clear signs of improvement, we expect there 
to be ongoing issues to be managed given the 
large, planned increases in production. Boeing 
also had specific issues with the cap on 737 
MAX production imposed following the Alaska

Further 2024 financial performance is 
described in the Divisional and Financial 
Review sections below. 
The Board has confidence in the Group’s 
performance, financial position and future 
prospects, and has approved a final dividend of 
1.65 pence per share (2023 – 1.70 pence). This 
will be paid on 30 May 2025 to shareholders on 
the register at close of business on 2 May 2025. 
This brings the total dividends, paid and 
proposed for 2024, to 2.40 pence per share 
(2023 – 2.30 pence), an increase of 4% 
year-on-year. We will continue to follow a 
progressive dividend policy reflecting earnings 
per share, free cash flow generation, market 
conditions and dividend cover.
Delivery of Group Strategy
We are committed to a sale of our 
Aerostructures business and are making 
good progress. There is good buyer interest, 
we are now at an advanced stage of a sale 
process with a small number of parties, 
and negotiations are progressing positively. 
We are focused on completing the sale process 
and maximising value for shareholders and 
will update the market in due course. This is 
in line with our strategy to position Senior as 
the market leading pure play fluid conveyance 
and thermal management business.  
Senior’s Purpose is “to help engineer the 
transition to a sustainable world for the benefit 
of all our stakeholders”. We do this by:
•	 Technology expertise – Using our 
technology expertise in fluid conveyance 
and thermal management to provide 
safe and innovative products for 
demanding applications in some of the 
most hostile environments.
•	 Customer transition – Enabling our 
customers, who operate in some of the 
hardest-to-decarbonise sectors, to transition 
to low-carbon and clean energy solutions.
•	 Climate action – Staying at the forefront 
of climate disclosure and action by 
ensuring our own operations achieve 
our Net Zero commitments.
Our extensive design expertise, intellectual 
property and know-how supports our strategic 
focus. We offer pivotal technologies for 
emissions reduction and environmental 
efficiency, whether that is for cleaner and more 
efficient conventional technology or new low 
carbon product offerings. 
We continue to invest in markets where we 
believe there is significant growth potential and 
where the Group’s skills and knowledge can be 
exploited, such as aerospace highly engineered 
standard parts/components. This market has 
high barriers to entry and attractive returns. We 
are broadening our product portfolio for specific 
products such as flanges, couplings and fittings. 
Our high-pressure hydraulic fittings business, 
Spencer Aerospace (“Spencer”) has continued 
to grow strongly with sales up by over 50% in 
2024 compared to 2023 and has now grown 
over 135% since we acquired the business in 
late 2022. 
Further information on Senior’s strategy 
and strategic priorities can be found on pages 
34 to 35. In addition, we will be providing 
further details on delivery of our strategy at 
our Investor Event on Monday, 3 March 2025. 
Market Overview
Civil Aerospace (46% of Group)
The civil aerospace sector continued its 
recovery with air traffic increasing in all regions 
during 2024. According to the International 
Air Transport Association (“IATA”), the latest 
data showed that total demand during the 
year, measured in Revenue Passenger Kms 
(RPKs), increased by 10% year-on-year. Air 
traffic is expected to continue to grow as 
incomes increase, especially in developing 
markets in Asia. The long-term demand for 
new aircraft is forecast to grow by 3-4% 
per annum driven by growth in air traffic 
and ongoing fleet replacement.
Airbus delivered 766 aircraft in 2024, compared 
to 735 deliveries in 2023. Airbus recently 
confirmed production rate targets are now: 
A220, 14 per month in 2026; A320 family, 
75 per month in 2027; A330 maintaining 
4 per month; and A350, 12 per month in 2028.
In 2024, Boeing delivered 348 aircraft compared 
to 528 deliveries in 2023. It has been well-
documented that Boeing faced challenges in 
2024. The Alaska Air 737 MAX incident in 
January 2024 led to the FAA imposing strict 
controls over Boeing production and capped 
production at 38 aircraft per month until the 
FAA agrees to further increases. The situation 
was exacerbated by an employee strike at 
Boeing’s Puget Sound facilities which lasted 
for 53 days during which time no aircraft were 
produced at the affected facilities. Production 
of aircraft resumed in mid-December.
Boeing reduced the production rate of its 787 
model from 5 aircraft per month to 3 for much 
of the year due to supply chain constraints, 
although production returned to 5 per month by 
the year end. Boeing further announced that the 
first delivery of the 777X will now be in 2026. In 
January 2025, the 777X program resumed FAA 
certification flight testing.
Embraer is forecasting that it will deliver 
between 77-85 commercial aircraft in 2025, 
up from 73 in 2024. It is also forecasting to 
deliver between 145-155 business jets in 2025, 
having delivered 130 in 2024. Global business 
jet activity was down by 1% year-on-year in 
2024 according to WingX. Global deliveries of 
business jets are anticipated to increase by 11% 
year-on-year in 2025 and by 2% per annum over 
the next decade, according to Honeywell’s 
Global Business Aviation Outlook.

Senior continues to be at the forefront 
of sustainability reporting and action. 
We believe that this is truly important 
and, evidently, so do many of our 
customers who are including 
commitment and progress on 
sustainability in their supplier selection 
decision-making process. In 2024, we 
made significant strides, including 
meeting our Near-Term science-based 
target for the reduction of greenhouse 
gases, a year ahead of the 2025 target 
date, and progressing our Double 
Materiality Assessment (DMA). Looking 
ahead to 2025, we will continue our 
focus on sustainability by supporting 
our customers in their carbon reduction 
efforts, and, having already achieved our 
Near Term Scope 1 & 2 SBTi accredited 
targets, our full focus now turns to 
meeting our 2040 Net Zero Scope 1, 2 
and 3 targets.
In 2024, we achieved significant milestones 
in our sustainability journey:
Environmental
•	 Awarded ‘A’ leadership score by CDP for 
our disclosure and action on climate change 
for 2024
•	 We continued to reduce our Scope 1 and 2 
greenhouse gas emissions, achieving a 
reduction of 33% against our 2018 
baseline, meeting our Near-Term science-
based target ahead of the 2025 target date.
•	 Electricity sourced from renewable energy 
increased to 52%, from 48% in 2023.
•	 We extended our support to suppliers yet 
to set carbon reduction targets and updated 
our Sustainable Sourcing Policy.
Social
•	 We undertook our annual Global Employee 
Engagement Survey in May 2024 and were 
pleased to see improvements in the 
participation rate, engagement, and health 
& wellbeing scores.
•	 Our Lost Time Injury Illness & Illness Rate 
in 2024 reduced by over 40% to 0.19, down 
from 0.32 in 2023.
•	 Currently, 56% of the Board Directors are 
female, including the Chair of the Audit 
Committee, the Senior Independent 
Director, who is also Chair of the 
Remuneration Committee, and the 
Group Finance Director. The Chair 
of the Audit Committee is also the 
non-executive Director with Board 
responsibility for employee engagement. 
Two of the Directors (22%) are from 
ethnic minority backgrounds.
Governance
•	 We deployed an enhanced Group 
Anti-Fraud Policy.
•	 We carried out a Group-level double 
materiality assessment. The results of 
the assessment will inform Senior’s 
approach to enhancing and evolving its 
sustainability strategy.

SENIOR PLC ANNUAL REPORT AND ACCOUNTS 2024
STRATEGIC  
REPORT

Defence (13% of Group)
Senior’s sales to the Defence sector are 
primarily focused on US military aircraft 
platforms such as the F-35 and C-130J.
Lockheed Martin has stated that they will 
continue to produce 156 F-35 aircraft per year, 
having delivered 110 in 2024. The total planned 
purchases of F-35s are over 3,500, of which 
31% is for the international market.
Adjacent Markets (9% of Group)
Sales from our Aerospace operating businesses 
into end markets outside of the civil aerospace 
and defence markets are classified under 
“Adjacent Markets” and include sales into 
the semiconductor equipment, space and 
medical markets.
In the semiconductor sector, global sales of 
wafer fabrication equipment grew by 7% during 
2024. This market is forecast to grow by a 
further 7% in 2025 driven by demand for 
AI-related chips. (Source: Semi.org)
Land Vehicle (19% of Group)
Demand in heavy-duty truck markets during 
2024 weakened in both Europe and North 
America, while the off-highway market 
remained subdued and light vehicle markets 
experienced mixed conditions.
According to Americas Commercial 
Transportation (“ACT”) research, North 
American heavy-duty truck production declined 
by 2% in 2024 compared to 2023, which was 
better than originally anticipated. This decline 
was due to ongoing overcapacity in the for-hire 
freight-logistics sector in the USA, which has 
resulted in low levels of profitability and fleet 
investment in the Class 8 “tractor” sector. ACT 
forecast production to decline by 5% in 2025 
and rebound in 2026 to 12% growth as a result 
of the pre-buy ahead of the planned 2027 
emission change.
Weak economic fundamentals, particularly in 
Germany, led to lower orders for and production 
of heavy-duty trucks in Europe during 2024. 
S&P Global (“S&P”) data shows that production 
was down 26% year-on-year, weaker than 
originally anticipated. S&P predict production in 
2025 to increase by 2%.
In the off-highway sector, demand for 
construction vehicles decreased in both North 
America and Europe in 2024. Demand for 
mining equipment remained positive in all major 
markets. Industry participants are forecasting 
that overall demand in the off-highway sector 
in 2025 will decline in North America between 
0% – 10%, be flat in Europe and increase 
between 0% – 10% in China.
European light vehicle production declined by 
7% in 2024 after two years of post-pandemic 
catch-up, as supply and demand became more 
balanced. Production in North America fell by 
2% in 2024, as four years of inventory 
restocking came to an end. In India, the other 
light-vehicle market to which Senior has 
significant exposure, production in 2024 
increased by 4%. This relatively low rate, by 
Indian market standards, was due to high levels 
of inventory. S&P is forecasting that production 
in 2025 will fall by 5% in Europe, by 2% in North 
America and increase by 6% in India.
Power & Energy (13% of Group)
2024 saw growth in upstream oil & gas 
expenditure slowing, especially in the Middle 
East, while remaining subdued in North America.
Activity in the downstream sector remains 
focussed in the Middle East and Asia, where 
cheap feedstock and economic growth 
respectively is driving demand.
Global electricity consumption grew by 4.3% 
in 2024 and is forecast to grow at 4% annually 
through 2027. Demand is being driven primarily 
by economic growth, urbanisation and the 
adoption of EVs.
Outlook
We are committed to a sale of our 
Aerostructures business and are making 
good progress. There is good buyer 
interest, we are now at an advanced stage 
of a sale process with a small number of 
parties, and negotiations are progressing 
positively. We are focused on completing 
the sale process and maximising value for 
shareholders and will update the market in 
due course. This is in line with our strategy 
to position Senior as the market leading 
pure play fluid conveyance and thermal 
management business. 
For the year ahead, the Board anticipates 
good growth for the Group, in line with its 
expectations. We are closely monitoring 
the impact on global trade from potential 
tariff changes.
Increasing aircraft build rates, operational 
efficiency benefits and improved contract 
pricing are expected to drive good growth 
in Aerospace in 2025, with H2 expected to 
be higher than H1.
For the full year, Aerostructures is expected 
to improve from a loss making position in 
2024 to an operating profit range of £9m 
to £11m in 2025, with the large majority 
of that being earned in H2.
We expect Flexonics performance in 2025 
to be broadly similar to 2024.
In land vehicles, the ramp up of 
programmes recently won means we 
expect our 2025 performance to be broadly 
similar to 2024, despite some softness in 
North America and Germany. In power and 
energy, activity levels are expected to be 
similar to 2024. 
Our strategy of positioning Senior as 
a pure play fluid conveyance and thermal 
management business in attractive and 
structurally resilient core markets; with 
active portfolio management; combined 
with our highly relevant technical 
capabilities; and sector-leading sustainability 
credentials, provides confidence of 
continuing performance improvements 
for the Group. Reflecting the Board’s 
confidence, we have announced new and 
improved medium term financial targets 
which will be discussed in detail at the 
Investor Event on Monday, 3 March 2025.

SUSTAINABILITY
In 2024, we carried out our first Double 
Materiality Assessment (DMA) for the Group. 
The DMA, aligned to the CSRD, assessed both 
financial and impact materiality.
Financial materiality is defined as matters 
which (may) generate risks or opportunities 
that could potentially have a material influence 
on the undertaking’s cash flows, development, 
performance, position, cost of capital or 
access to finance over the short, medium, 
and long-term time horizons.​
Impact materiality is defined as matters 
which could have an actual or potential 
significant impact on people or the environment 
over the short, medium or long term, caused 
or contributed to by the undertaking’s own 
operations, products, or services or through 
its business relationships.​
The results of the DMA process are shown in 
the table below. The risks and impacts identified 
as part of this assessment have been mapped 
against the Group’s principal risks disclosed on 
page 54 to 59. Appropriate mitigation measures 
are already in place to manage these risks 
and to take advantage of the opportunities.

2. Stakeholder engagement 
and shortlisting  
1.	Landscape Review – the objective of the 
landscape review was to identify the 
comprehensive list of sustainability topics that 
the Company should consider through the 
DMA. A comprehensive list of topics was 
identified and thoroughly reviewed.
2.	Stakeholder Engagement Process – the 
stakeholder engagement process began with 
mapping Senior’s value chain, which identified 
key activities, materials, geographies and 
stakeholders. Following the value chain 
mapping exercise, a list of stakeholder groups 
was identified. We selected a diverse range 
of internal and external stakeholders for direct 
engagement, ensuring they represented a 
variety of perspectives and a mix of 
geographies, business/market expertise and 
commercial relationships with Senior. Where 
the direct engagement was not possible, we 
used alternative information to gather insights. 
As a result of the engagement process, we 
validated the long list of sustainability topics, 
identifying Impacts, Risks and Opportunities 
(IROs) from a wide range of perspectives. 
Following engagement with stakeholders, the 
short list of sustainability topics and their 
associated IROs were identified.
3.	Analysis – a scoring tool, designed in line 
with the European Financial Reporting 
Advisory Group (EFRAG) guidance, was used 
to score each IRO related to each short-listed 
topic. To score Impact Materiality, each topic 
was assessed according to the European 
Sustainability Reporting Standards (ESRS) and 
EFRAG double materiality guidance against 
three parameters to determine its severity: 
scale, scope and irremediability. To score 
Financial Materiality, the calculation 
considered how each issue might affect 
Senior financially in terms of revenues, fines 
and remediation, profit, cost of capital and 
asset value. This was aligned with Senior’s 
existing guidance for assessing likelihood of 
occurrence and impact.
4.	Validation – the scoring results were 
presented to the Executive Committee 
and the Board in December, who performed 
the final validation of the double materiality 
matrix. The matrix will provide a framework 
for Senior to prioritise its efforts in addressing 
sustainability-related risks, impacts 
and opportunities.

mitigate these risks and build a sustainable 
future for generations to come.
Progress towards our certified 
Science-Based Targets
Scope 1 and 2 Carbon Emissions
Scope 1 emissions encompass greenhouse gas 
(GHG) emissions directly generated by our 
operations, including those from natural gas 
combustion, owned transport, and refrigerant 
use. Scope 2 emissions, on the other hand, refer 
to indirect GHG emissions resulting from the 
energy purchased by our organisation, 
predominantly electricity.
As part of our certified science-based targets, 
we remain steadfast in our commitment to 
reducing these emissions. Our carbon reduction 
programme focuses on:
•	 Enhancing energy efficiency across 
our operations.
•	 Increasing on-site renewable 
energy generation.
•	 Sourcing low-carbon electricity where 
available to further minimise our 
environmental footprint.
Through these initiatives, we are driving 
meaningful progress toward achieving our 
climate goals while supporting the global 
transition to a sustainable, low-carbon future.
In 2024, our businesses remained focused 
on improving energy management and 
monitoring, expanding on-site solar generation, 
and upgrading plant and equipment with 
energy-efficient alternatives. These efforts 
yielded measurable outcomes:
•	 Total energy usage decreased by 1%.
•	 On-site solar generation was extended, 
with the facility in the Czech Republic, 
installed in 2023 achieving full operational 
output. Existing solar photovoltaics (PV) 
installations in Thailand, Malaysia, 
and India continued to contribute to our 
renewable energy mix.
These achievements reflect our ongoing 
commitment to reducing our environmental 
footprint and advancing toward our certified 
science-based targets.
Progress on Near-Term 
Science-Based Targets
We remain ahead of our 2025 Near-Term 
Science-Based Target, demonstrating our 
commitment to meaningful and measurable 
climate action:
•	 Achieved a 5.6 %reduction in total Scope 1 
and 2 emissions (market-based) in 2024 
compared to 2023.
•	 Achieved a 33.4% reduction in Scope 1 
and 2 emissions against our 2018 baseline.
•	 Increased the sourcing of renewable 
electricity to 52% in 2024, up from 48% 
in 2023.
These accomplishments reflect our dedication 
to operational efficiency, renewable energy 
sourcing, and maintaining a trajectory toward 
carbon neutrality by 2040.
Scope 3 emissions and supply 
chain engagement
Scope 3 emissions arise from activities 
beyond Senior’s direct ownership or control, 
encompassing carbon emissions indirectly 
influenced by our value chain. These emissions 
extend beyond Scope 1 and 2, making them 
a critical area for addressing our overall 
carbon footprint.
To effectively reduce Scope 3 emissions, we 
recognize the importance of robust engagement 
with our supply chain, as purchased goods and 
capital goods represent the largest contributors 
to our Scope 3 profile. Since 2021, we have 
partnered with CDP to work collaboratively with 
our suppliers, adopting best practices to drive 
progress toward our Scope 3 (supplier 
engagement) Science-Based Target (SBTi).
This partnership exemplifies our commitment to 
fostering sustainable practices across our value 
chain and achieving impactful climate action.
Recognition for CDP Supplier 
Engagement Programme efforts
In 2023, we received an “A” rating for our 
efforts in the CDP Supplier Engagement 
Programme. This prestigious recognition is 
awarded only to the most committed 
companies actively working to reduce 
greenhouse gas emissions across their supply 
chains. It underscores our dedication to driving 
meaningful climate action in collaboration with 
our suppliers.
We eagerly await the announcement of our 
2024 score, reflecting our continued 
commitment to sustainability leadership.
As part of CDP’s supply chain engagement 
programme, we identified and engaged with 
over 300 of our key suppliers in 2024. In 
addition, we initiated an analysis of carbon 
reduction commitments among suppliers not 
yet participating in the CDP process.
To support those yet to embark on this journey, 
we have developed a simple carbon target tool 
aligned with the principles of Science-Based 
Targets. This tool provides practical guidance 
to help suppliers establish and implement their 
carbon reduction goals.
When evaluating Purchased Goods and 
Services, we include approximately 320 of 
our suppliers. This approach aligns with our 
Science-Based Target, which requires that 
82% of our suppliers, by spend, establish 
a Science-Based Target. 
Ninety-one of our key suppliers have declared 
they have set carbon reduction targets. This has 
been helped by support through the CDP supplier 
programme, and the Senior sustainability team. 
The data we receive from our suppliers is useful 
to us when we calculate our Scope 3 Purchased 
Goods carbon emissions, we are able to use this 
data to increase accuracy for this calculation.
 Our latest Scope 3 emission data can be found on

SUSTAINABILITY
ENVIRONMENT
Methodology 
The Group’s approach to calculating and reporting 
our GHG emissions follows the GHG Protocol 
on how to measure and monitor GHG emissions. 
Three data sources are used to calculate 
GHG emissions:
1. UK Government GHG Conversion factors for 
company reporting (Defra full set for advanced 
users 2024).
2. US EPA (eGRID) Emission factors for greenhouse 
gas inventories for US electricity generation 
(2024Version). 
3. IEA (International Energy Agency) Emission 
factors year 2024 Edition. Reporting has 
incorporated Scope 2 greenhouse gas emissions 
(associated with electricity consumption) 
calculated using both the location and market-
based methods. Data for the market-based, 
utility emission rates has been collated during 
the period December 2024 – January 2025, 
as best available information to represent the 
emissions during the year. It should be noted 
that these vary and are periodically updated,
so are representative of our best endeavour to 
determine market-based emissions at the 
time of collating data for this report.
Each Senior business reports its environmental 
performance monthly using the Group’s financial 
reporting process. 
The Scope 1 and 2 emissions location-based  
and market-based (FY24) are independently  
assured in accordance with the International  
Standard on Assurance Engagements ISAE 3410 
(limited assurance). 
In calculating GHG emissions, the Group has 
used the control approach and more specifically the 
financial control approach under which a company 
accounts for 100% of the GHG emissions from 
operations over which it has control. This covers  
all wholly owned operations and subsidiaries of  
the Group for financial reporting purposes.
Limited Scope 3 emissions are reported in the table 
above, they are not externally verified at the time of 
publication of this Annual Report and Accounts. 
A full disclosure of the 2024 Scope 3 emissions, 
externally verified, will be made publicly available 
within our CDP Climate Change Disclosure, publically 
available later in 2025.
Total waste includes the reported production  
and non-production-related hazardous and 
non-hazardous solid, sludge and liquid materials 
(including wastewater since 2019) that is sent off 
site for disposal, treatment, reprocessing, recycling 
or reuse by others. Waste materials do not include 
by-products or scrap from a Senior business 
process which are re-used in a production process. 
Similarly, waste that arises from construction and 
other maintenance/remediation work performed by 
third-party contractors are not included in the scope 
of reporting where the contractor is responsible for 
the disposal of the waste. Defra conversion factors 
are used worldwide for waste data as means to 
determine a reasonable carbon conversion factor.
Water volumes are obtained from meter  
readings and from supplier invoices. All water 
consumption is converted to megalitres, carbon is 
derived using recognised and appropriate Defra 
carbon conversion factors.
For vehicle and air mileage, Senior uses the most 
applicable Defra conversion factors to calculate  
the carbon based on distance travelled.

STRATEGIC  
REPORT

Energy efficiency actions 
In the reporting year, we have continued to 
implement energy efficiency projects across our 
global operations. In total, Senior’s 
environmental improvements in 2024 have the 
potential to reduce annual GHG emissions by 
1,360 tonnes of CO2e.
These improvements include enhancing energy 
efficiency in buildings through insulation 
upgrades, heating, ventilation, and air 
conditioning (HVAC) improvements, as well as 
further installations of LED lighting. 
We remain focused on improving energy 
efficiency in production processes, including 
machine and equipment upgrades, compressed 
air system optimisation, and heat recovery 
initiatives. Eleven Senior operating businesses 
have implemented advanced energy monitoring 
software, providing granular insights into 
consumption trends across gas, electricity, and 
water usage. These systems enable plants to 
analyse energy consumption by service 
category, benchmark against baselines, and 
assess cost impacts via interactive dashboards. 
They also help detect anomalies, facilitating 
prompt investigations and corrective actions.
All of Senior’s UK operating businesses and our 
Group Head Office are now powered by 100% 
renewable electricity. Additionally, Flexonics 
Kassel Germany and Aerospace Metal Bellows 
Boston USA have secured 100% renewable 
electricity contracts, collectively avoiding 4,000 
tonnes of GHG emissions annually.
In the US, our SF Bartlett site continues to 
purchase renewable energy at a 50% renewable 
tariff, with other Senior sites making steady 
progress toward securing similar contracts. Our 
commitment to solar power also continues to 
grow, with Flexonics Olomouc solar installation 
achieving full operational status in 2024, capable 
of reducing GHG emissions by 40 tonnes 
annually. With this addition, the total number of 
our sites equipped with on-site solar 
photovoltaic (PV) systems now stands at four.
Waste 
In 2024, we conducted a comprehensive review 
of waste streams across all our global 
operations. This effort enabled us to enhance 
data collection, providing a more detailed 
delineation of our waste categories.
Our waste recycling rate experienced a slight 
decline, decreasing from 95.1% in 2023 to 
91.1% in 2024. This was largely influenced by 
a reduction in production activity in our Pacific 
North West businesses due to customer strike 
in the second half of 2024 and increased landfill 
use , which will be a focus in 2025. Eleven of 
our operational sites achieved zero waste to 
landfill in 2024. 
Looking ahead to 2025, we are placing an even 
stronger emphasis on waste reduction and 
recycling, with a particular focus on improving 
recycling rates in regions where local 
infrastructure supports it.
 For information on hazardous waste, please see: 
www.seniorplc.com/sustainability
Water 
At Senior, our objective is to minimise the 
environmental impact of our production 
processes by optimising water usage, 
particularly in regions facing significant water 
scarcity. Aware of the growing strain on global 
freshwater reserves, we are committed to 
identifying areas of high water risk and 
implementing strategies to reduce freshwater 
consumption in these regions.
We utilise tools such as the World Wide Fund 
for Nature (WWF) Water Risk Filter to pinpoint 
businesses located in water-scarce regions, 
enabling us to target our efforts where they are 
needed most.
In 2024, our proactive measures proved 
effective, resulting in a reduction of our overall 
water consumption to 240 megalitres, down 
from 260 megalitres in 2023.
 For information on water, please see 
www.seniorplc.com/sustainability
Certification
All Senior legacy businesses hold ISO 14001 
accreditation, reflecting our commitment to 
robust environmental management practices. 
In 2024, our recent acquisition, Spencer 
Aerospace, began its journey toward 
achieving this accreditation, with a target 
to secure it in 2025.
At Senior, the Environmental Management 
System (EMS) under ISO 14001 is more than 
a framework it is a collaborative effort that 
unites our teams in pursuit of shared 
environmental goals. By fostering a culture 
of transparency and celebrating achievements, 
we inspire and engage our staff, cultivating 
a cohesive and motivated workforce dedicated 
to environmental stewardship.

The WWF Water Risk Filter analysis conducted in 
2022 indicated that nine of our operating businesses 
were in areas of potential water scarcity. These are 
our businesses in India, South Africa and California 
(Senior Aerospace SSP, Senior Aerospace Jet 
Products, Senior Aerospace Ketema, Senior 
Aerospace Steico Industries and Senior Aerospace 
Spencer), as well as our Flexonics and Aerospace 
businesses in Mexico. To date, Senior has not been 
subject to conditions where water scarcity led to 
interruptions in operations, although we are aware that 
severe localised water shortages can lead to potential 
operational interruption and interrupted supply of 
products to our customers. We continue our focus 
on opportunities to reduce overall water consumption 
in each of these businesses.

Products and services
Regulation and growing awareness of climate change are influencing 
customer preferences and increasing demand for energy efficient 
transportation, such as hybrid, fully electric and hydrogen powered 
vehicles. Senior is actively involved in this sector, offering innovative 
thermal management solutions for large battery packs to Land Vehicle 
markets (for public transport vehicles, commercial vehicles and some 
passenger vehicles). The Aerospace market is equally focused on 
energy efficiency, and Senior is working directly with several OEMs in 
areas such as the handling of sustainable fuel and the safety-critical 
conveyance of hydrogen within an aircraft. The Company has an 
opportunity to lead in this technology, leveraging its expertise in 
designing products with class-leading technical performance, which 
has the potential to increase sales in this growing market sector. 
Examples of this include battery cooling, electronics cooling, electric 
vehicle fluid handling and flex for vehicle range extenders, fluid 
conveyance hoses and tubes for hydrogen fuel cells. 
Our engineering experts are working on exhaust gas recirculation 
(“EGR”) systems with customers, addressing requirements that are 
driven by performance (lower carbon emissions) and the evolving 
legislation. Legislation drives lower NOx allowances for heavy-duty 
diesel engines. We recognise that internal combustion engines will 
be in operation for some time to come, that we need to keep on 
improving their energy efficiency, and that this will also contribute 
to improving transportation efficiency, alongside the roll-out of 
electric vehicles.
We continue to explore the use of specialised additive manufacturing 
equipment in some of our Aerospace businesses with a dual 
purpose: to develop and manufacture lighter metallic components, 
thereby reducing weight and, ultimately, saving fuel and reducing 
carbon emissions during flight. At the same time, lighter components 
will reduce waste in the production process, thereby decreasing the 
amount of material required (reducing our Scope 3 emissions) and 
the associated material cost.

Operations and supply chain
Climate change considerations are essential to energy efficiency and 
cost reduction strategies across Senior’s operating businesses. 
Transitioning to renewable energy sources and, subsequently 
reducing Scope 1 and 2 emissions, has been an integral part of the 
Group’s sustainability efforts for several years. Further information 
can be found on pages 15 to 17. We continued focusing on energy-
efficient initiatives, such as improving building insulation, upgrading 
energy efficient lighting, installation of heat recovery systems and 
upgrading HVAC systems.
In 2024, we continued our collaboration with suppliers through the 
Carbon Disclosure Project (CDP), encouraging them to disclose their 
environmental data. Ninety-one of our key suppliers have declared 
they have set carbon reduction targets. In addition, Senior updated 
its Sustainable Sourcing Policy defining expectations for its suppliers 
to set and make progress towards their own science-based targets 
and environmental preservation goals.
Each site within the Group has a scenario-based Business Continuity 
Plan which is tested annually. This ensures that mitigation and 
adaptation measures related to the physical risks of climate change 
are addressed effectively. Further information on how we manage 
the risk of climate change can be found on page 55.

STRATEGIC  
REPORT

Impact of climate-related risks and opportunities on the organisation’s businesses, 
strategy and financial planning continued
Investment in research and development
Climate change is a fundamental element of the Group’s business 
strategy. Senior’s products and services help our customers reduce 
carbon emissions in Aerospace, from industrial process plants and 
from land vehicles. When we consider R&D spend and expansion, 
we assess sustainability of our products in terms of supporting 
our customers’ aims to reduce energy consumption and carbon. 
For example, the development of new thermal management 
technology (e.g. components for fuel cells, advanced heat 
exchanger solutions, using laser welding for battery cooling plates) 
presents an opportunity for Senior to become a leader in the 
specialised applications of off-road vehicles, large trucks and 
aerospace, where reduced weight and optimum working 
temperature are critically important.
Access to capital
Sustainability remains an important factor for our investors and 
lenders when allocating capital. Senior’s focus on sustainability 
leadership in its own operations and that of its suppliers, as well as 
supporting customers in their transition journey to Net Zero, will help 
Senior’s financing needs in the future whether raising debt or equity. 
The Group’s main syndicated Revolving Credit Facility of £115m is a 
sustainability-linked loan with Key Performance Indicators on carbon 
emission reduction and waste recycling rates.
Acquisitions or divestments 
Portfolio optimisation is a central pillar of our strategy. Whenever we 
analyse companies as potential acquisition targets, we carry out an 
assessment of that company’s ESG credentials, including how its 
products will enhance the sustainability of our own portfolio, whether 
that company is committed to decarbonisation and has stated Net 
Zero targets, and how much that company is investing in improving 
the local communities in which it operates. Should we reach the 
stage of conducting due diligence on an acquisition target, we will 
conduct a full ESG analysis, potentially with external professional 
support. In terms of strategic fit, we will also assess the future 
markets of the company’s products to ensure alignment with our 
own ambition of supporting decarbonisation in difficult markets, 
like Aerospace, Land Vehicle and Oil & Gas.
Financial planning process
The Group’s operating businesses have maintained their focus on 
internal efficiencies, particularly associated with Scope 1 and 2 
emissions and made significant improvements as part of Senior’s 
energy sustainability priorities, as described on page 15.
The Group monitors carefully the impact on demand for its products 
related to the transition to a low-carbon economy. For example, 
although some of Senior’s operating businesses are seeing a 
reduced demand as a result of the decreasing market trend for diesel 
passenger vehicles in Europe, the overall effect in the Group is not 
significant as other product lines are filling demand. We are tailoring 
our financial planning to reflect these market changes. At the same 
time, the Group considers opportunities in new technologies that 
may require investment.
We consider climate change when assessing liabilities in the Group’s 
operating businesses. The need to insure fixed assets and the 
adoption of safety measures to protect staff in areas subject to 
severe weather are current examples.

Resilience statement
Having established our Long-Term Net Zero 
Targets, aligned to 1.5ºC for all Scopes, 
we are taking proactive steps to ensure Senior’s 
operations remain resilient to the effects of 
transitional risks associated with scenarios 
1 and 2. As part of our Energy Hierarchy, we 
shall continue prioritising energy efficiency 
initiatives and the use of renewable energy.
We actively engage with our suppliers, requiring 
them to set and make progress towards their 
own science-based targets and environmental 
preservation goals, and to integrate sustainable 
practices into their operations. This will help 
create a stronger and more resilient supply chain 
that is aligned to Senior’s sustainability goals. 
The Group’s focus on innovation and strong 
relationships with customers means we are well 
positioned to maximise opportunities offered 
by smooth and disruptive transition scenarios. 
We are proactively assessing the way climate 
change affects market demand for our products 
as part of our annual strategic meetings. 
The physical impacts of climate change 
associated with scenario 3 could be significant. 
The Group’s business continuity plans play an 
important role in maintaining resilience against 
the potential physical impacts of climate change. 
By identifying potential vulnerabilities and 
implementing adaptive measures, the operating 
businesses will be well placed to maintain their 
functions, minimise operational disruptions and 
ensure long-term stability.

No policy action: 
business as usual
•	 Decisive carbon action to reduce global 
emissions starts in 2021.
•	 Carbon taxes and other policies intensify 
gradually over the scenario horizon.
•	 Global warming is limited to 1.8ºC by 
2050 compared to pre-industrial levels.
•	 Limited physical risks.
•	 Delay in implementing the policy required 
to reduce global emissions by 10 years.
•	 Starting in 2031, significant and rapid 
policy action causing drastic bending of 
emissions trajectory globally.
•	 Global warming is limited to 1.8ºC by 
2050 compared to pre-industrial levels.
•	 Limited physical risks.
•	 Governments fail to introduce further 
policies to address climate change 
beyond those already implemented.
•	 Increase in global temperatures 
reach 3.3ºC by 2050 compared 
to pre-industrial levels.
•	 High physical risks.
Potential impact
Policy changes start to accelerate, and 
consumer and investor preferences evolve 
rapidly to facilitate decarbonisation.
In the short and medium term, Senior 
needs to ensure that its investment 
decisions are consistent with its science- 
based targets and deliver expected results.
In the long term, it is important to keep 
pace with changing market demand for 
low-emission products and remain 
consistent between Senior’s public 
commitments and market expectations.
Potential impact
A sudden increase in the intensity of 
climate policy in 2031, following an initial 
period which is characterised by insufficient 
or ineffective emission reducing policies.
Senior needs to ensure that it takes action 
over this time period to avoid disruption in 
the long term as mature economies make 
rapid strides to cut emissions.
Potential impact
Absence of transition policies result in 
a growing concentration of greenhouse 
gas emissions in the atmosphere.
Increased exposure to heatwaves, tropical 
cyclones and droughts may increasingly 
provide challenge for some of Senior’s sites 
and supply chains.
With less policy action and investment 
driving forward technology development, 
the costs of transitioning to the new 
technologies may be higher, the likelihood 
of successful implementation and the 
relative rewards for the investment may 
be lower.
Opportunities
The ability to maximise returns on new 
investments in the long term, once 
transition has occurred and markets 
have stabilised.
Opportunities
Early investment can set the Group up to be 
ready for the swift changes to the disrupted 
economy after 2030.
Opportunities may materialise over the long 
term, due to the late policy action and the 
abrupt transition to a low-carbon economy.
Opportunities
The Group’s continued investments and its 
ability to diversify business activities can 
help Senior be more resilient to changes 
in the markets and adapt to the impacts 
of climate change.
Resilience of the organisation’s 
strategy with reference to three 
climate-related scenarios, including 
a 2ºC or lower scenario
In 2021, we carried out scenario analysis to 
understand the potential impact of climate 
change on the Group’s operations. We selected 
the three climate scenarios produced by the 
Bank of England because:
•	 they meet TCFD recommendations to assess 
business resilience at different climate-related 
scenarios, including a 2ºC or lower scenario;
•	 these scenarios are used by the Bank of 
England to explore resilience of the UK 
financial system to climate change;
•	 the scenarios are modelled to a 30-year 
timespan, out to 2050 to align to the Paris 
Agreement and other Net Zero 2050 targets;
•	 they consider the macroeconomic impacts 
with more granularity and within a more 
applicable business context than climate 
scenarios based on temperature increases; 
and
•	 multiple high transition scenarios provide 
diversity in stress tests.
Further information on the assumptions 
and parameters used in the scenarios 
can be found on the Company’s website.

Metrics used to assess climate-related 
risks and opportunities
Targets used to manage climate-related 
risks and opportunities and performance 
against targets
The table below illustrates targets and metrics 
we have selected to measure our climate-
related risks and opportunities. We have chosen 
these metrics because we consider that they 
are relevant to the climate-related risks and 
opportunities facing Senior and regulatory and 
stakeholder expectations. Our targets, which are 
aligned to the Paris Agreement and the UK’s Net 
Zero Strategy, demonstrate our commitment to 
reduce the GHG emissions of Senior’s 
operational activities, as well as addressing 
indirect emissions within our value chain. Our 
near-term Scope 1, 2 and 3 targets were verified 
by SBTi in 2021. In 2023, the SBTi approved our 
Long-Term Net Zero climate targets for Scope 1, 
2 and 3 emissions. The targets, to be achieved 
by 2040, aligned to 1.5ºC for all Scopes.
We continue to develop our high-level plan to 
reduce our emissions in line with our 2040 Net 
Zero targets against our 2018 base year. In 
2024, we have worked to refine our Scope 3 
calculation methodology, and in 2025 we will 
undertake further work to produce a more 
granular transition plan.
In 2024, the Remuneration Committee aligned 
remuneration for the executive Directors and 
senior management to non-financial 
performance metrics and agreed that 10% of 
the 2024 bonus potential would be determined 
by a target related to absolute reduction in 
Scope 1 and 2 emissions over the one-year 
performance period. The set target is consistent 
with the Group’s SBTi-validated target of a 30% 
reduction in these emissions by 2025 (from a 
2018 base year).

Risk management
Metrics and targets
The organisation’s processes for 
identifying, assessing and managing 
climate-related risks
We identify, assess and manage the Group’s 
risks using the risk management process shown 
on page 52. The Committee of Sponsoring 
Organisations of the Treadway Commission 
(“COSO”) enterprise risk management 
integrated framework is used as the foundation 
of the Group’s risk management process, 
tailored to reflect Senior’s culture and Values. 
The process includes identification of relevant 
risks, risk scoring, development and assignment 
of response actions, monitoring the 
effectiveness of key mitigating controls and 
reporting of the risk and assurance environment 
to the Executive Committee, the Audit 
Committee and the Board.
In response to the upcoming CSRD reporting 
obligations, we revised our annual assessment 
of Group-level sustainability risks, impacts and 
opportunities (including climate-related) using 
the DMA described on page 13. Climate-related 
risks, impacts and opportunities were identified 
based on landscape review of our internal 
documents, industry bodies and regulators, 
investor ratings, customers, peers and sector 
reports. Further discussions were held with 
Senior’s internal and external stakeholders to 
gain their perspective on which topics they 
considered to be potentially material, resulting in 
a high-level, quantifiable short list of topics. Each 
short-listed topic arising over the short, medium 
and long term was scored based on impact and 
financial materiality, as described below:
•	 Impact materiality – each topic was 
assessed according to the ESRS and the 
European Financial Reporting Advisory Group 
(EFRAG) double materiality guidance against 
three parameters to determine its severity: 
scale, scope and remediability.
•	 Financial materiality – the calculation for 
financial materiality considered how each 
topic might affect the Group financially in 
terms of revenues, profit, cost of capital and 
asset value. This was aligned to Senior’s 
existing risk management process, where 
scoring was based on the likelihood of a risk, 
as well as the magnitude of the affect in 
terms of operating profit and revenue.
For our 2024 DMA, short-listed sustainability 
topics were assessed on inherent basis. The 
results of the DMA were reviewed by the 
Executive Committee and the Board.
In 2023, Senior Flexonics Bartlett was selected 
as one of the operating businesses to pilot an 
assessment of climate-related risks and 
opportunities. The site completed its initial 
assessment in 2024, and the results generally 
aligned with the Group-level climate-related 
risks and opportunities. Feedback gathered from 
this pilot assessment will be considered as the 
Group develops its operating business-level 
climate-related risks and opportunities 
assessment programme for the future.
Mitigating action plans, including a detailed 
description of the response action, assigned 
to the members of the Executive Committee 
and other senior members of staff, are 
developed for all material climate-related risks. 
Action plan progress is tracked to ensure timely 
implementation. The overall effectiveness of the 
risk control environment is closely monitored 
through assurance and audit activities to assess 
if critical risks are being mitigated within the 
Group’s risk tolerance.
Integration of processes for identifying, 
assessing, and managing climate-related 
risks into the organisation’s overall risk 
management framework
Climate-related risks and impacts form part of 
the Group’s risk register and will be subject to 
an annual review by the Executive Committee 
and the Board.

Safety at Senior
At Senior, we foster a global safety culture that 
begins with senior leadership and permeates all 
levels of our global operations. 
This year, through sustained effort, we 
achieved a reduction of over 40% in our 
Lost Time Injury and Illness Rate, building 
on an already strong performance.
Our safety initiatives are driven by internal risk 
management Standards and critical 
controls, which include:
•	 22 specific prevention and risk 
management standards addressing 
the core hazards of our business;
•	 Ten Golden Rules for Safety; and 
•	 a Behavioural Safety Standard designed 
to prevent injury by supporting a positive 
safety culture. 
Each standard is supported by critical controls 
that are carefully implemented and monitored 
to prevent fatalities and reduce the risk of 
serious injuries or incidents.
Our ongoing safety training and 
communication form the backbone of our 
commitment, empowering employees and 
contractors to proactively prevent incidents 
that could result in injuries, illnesses, 
or environmental damage.
In 2024, we continued a thorough review and 
update of our safety standards and critical 
controls, building on the progress initiated in 
2023. These updates focused on making the 
standards more accessible and were reinforced 
with new posters and videos to enhance 
understanding and practical application across 
our sites.
Through these collective efforts, we remain 
steadfast in our goal to safeguard our people, 
operations, and environment.
Health and Safety
Injury prevention at Senior
At Senior, safety extends beyond merely 
avoiding incidents it encompasses a proactive 
approach to implementing effective controls 
that prevent and mitigate potential outcomes.
Our safety teams continuously analyse trends 
in incidents and injuries across our global 
operations, identifying location-specific or 
role-specific concerns. When necessary, they 
develop injury reduction plans tailored to 
address these issues. These plans incorporate:
•	 safety controls to mitigate risks;
•	 targeted training to enhance awareness 
and skills;
•	 work design adjustments to promote 
safer practices;
•	 specialised programmes to address 
recurring challenges; and
•	 engagement campaigns to reinforce the 
importance of safety at all levels.
Through these initiatives, we remain dedicated 
to fostering a safer workplace for all visitors to 
our sites.
Contractor safety 
At Senior, our safety commitment extends to 
everyone on-site, including temporary workers, 
contractors, and on site visitors. We have 
established contractor-specific safety 
programmes with tailored requirements and 
rigorous prequalification processes to uphold 
the highest standards of protection.
Our contractor management procedures 
require all personnel to complete a 
comprehensive onboarding process before 
commencing work. This ensures that everyone 
on site is informed about safety protocols, 
understands potential hazards, and is equipped 
to work safely.
These measures reflect our unwavering 
dedication to safeguarding every individual 
on site, ensuring they leave the workplace 
as safely as they arrived.
2024 injury performance highlights
In 2024, we made significant strides in 
improving workplace safety. Our Lost Time 
Injury and Illness Rate (LTIR) decreased to 0.19, 
marking a 41% improvement from the 2023 rate 
of 0.32. Additionally, our Total Recordable Injury 
and Illness Rate (TRIR) which accounts for lost 
time, job transfers, and minor medical 
treatments remained stable at 0.63.
In 2024, there were no work-related fatalities

SUPERVISOR BEHAVIOURAL 
SAFETY PROGRAMME 
In 2024, we launched a safety programme 
specifically designed for our supervisory-level 
employees. This initiative is built around our 
Senior Safety Behaviour Standard and 
delivered through face-to-face workshop 
sessions at our business sites. The 
programme focuses on coaching supervisors 
to identify and reward positive safety 
behaviours while emphasising the importance 
of fostering a proactive safety culture.
Developed in Q2 2024, the programme began 
rolling out in Q3, with additional workshops 
planned for 2025 to further embed these 
practices across our operations.

Our core Values underpin our culture 
At Senior we are committed to ensuring equal 
opportunities, fairness of treatment, work-life 
balance, and the elimination of all forms of 
discrimination in the workplace for employees 
and job applicants. Senior’s leaders aim to 
create a working environment in which everyone 
can thrive, achieve their full potential, and 
contribute to the success of Senior, and where 
all decisions are based on skills and merit. 
We recognise that good business decisions 
are based on gathering different perspectives. 
We encourage individuals to speak freely, 
respecting alternative views and cultures. 
Equality, diversity and inclusion
Senior promotes a culture and working 
environment in which everyone can make 
the best use of their skills, free from 
discrimination or harassment. Our Values define 
how we treat people, and in our 2024 Global 
Employee Opinion Survey we saw improved 
scores for all of our Values including respect and 
trust. We expect employees to treat everyone 
they meet in the course of business with 
respect and dignity, reinforcing our commitment 
to be open and straightforward with colleagues, 
customers, suppliers and other stakeholders. 
As well as our Vaues, the right behaviours are 
reinforced in our people policies and processes, 
for example, talent acquisition, succession 
planning, promotions and learning and 
development opportunities. 
In 2024, we updated our Code of Conduct 
with every employee receiving a personal copy. 
The Code has specific sections explaining 
how we value diversity and inclusion and 
emphasising that we are committed to 
preventing discrimination, harassment and 
bullying. The Code of Conduct and Human 
Rights policy are translated into our designated 
languages, and we included a module on 
Unconscious Bias in the 2024 Code of 
Conduct training. 
The Executive Committee and business leaders 
continue to focus on providing a diverse and 
inclusive workplace. Gender diversity receives 
much attention in Senior, and we believe that 
there remains an opportunity for further 
improvement, particularly in our operating 
businesses general management. To support 
our objective to increase the number of women 
in these operational leadership roles we have 
launched a Women’s Network, creating a 
steering committee to lead the network and 
identifying an executive sponsor. We are 
confident that the network will provide a forum 
to empower individuals as it will bring women 
across Senior together to discuss ideas and 
shared experiences in a supportive and 
productive environment, creating strong 
peer-to-peer support and confidence, as well 
as providing an impartial and open forum to 
encourage and inspire.

INFORMATION

People and culture
In our autonomous and collaborative Business 
Model, operating business leaders are 
empowered and accountable for setting the 
tone for their operations, guided by our Values. 
In May 2024, we ran our Global Employee 
Opinion Survey. We partner with Workday, 
a market leading provider to run the survey 
and deliver it in multiple languages. 85% of our 
employees completed the survey, which for 
a manufacturing business where around 
two-thirds of our employees do not have ready 
access to a computer, is an excellent response 
rate. The survey provided a wealth of valuable 
information in relation to our culture. Following 
the survey, operating business leaders worked 
with their HR leads to understand what they do 
well and areas for improvement. 
The overall engagement score increased from 
7.2 in October 2022 to 7.5 in May 2024. The 
survey identifies “Drivers” which are key areas 
measured in the survey that drive engagement. 
In 2024, the Drivers that were most improved 
were Reward, Strategy, and Workload. The 
scores improved in all areas other than Goal 
Setting and Freedom of Opinions, which stayed 
the same as the prior survey, and Environment 
which showed a small decline. This decline in 
the Environment score was driven by a 
reduction in the score for Informal Space and 
around half of our businesses have identified 
working environment as an area to take further 
action in 2024/25. Every operating business 
developed action plans based on the survey 
feedback and shared them with their teams. 
In 2024, we also asked employees “How do 
you feel about Senior’s Purpose which is to 
‘Help engineer the transition to a sustainable 
world for the benefit of all our stakeholders’?”. 
In the main, our employees were positive about 
Senior’s Purpose with comments such as 
“I feel proud to be part of an organisation that 
prioritises engineering”, “it’s inspiring to be 
part of an organisation that prioritises 
sustainability” and “I am proud to be part 
of this”. However, it was clear that some 
employees did not see themselves as 
stakeholders highlighting that additional 
communication around this would be beneficial. 
We remain focused on recruiting and retaining 
talent to sustain business resource requirements 
and growth. In order to meet our short and 
long-term talent requirements, we have 
continued to build strong relationships with 
local technical colleges, universities and 
education establishments, as well as partnering 
with recruitment firms. We are extending our 
use of job boards and other approaches to 
advertising and attracting applicants to build a 
strong talent pipeline. We have completed the 
roll-out of Recruit, our talent acquisition system, 
to all our UK and US businesses, thereby 
enhancing the candidate experience. The job 
market remains competitive for certain 
geographies and skills, and we have worked 
hard to secure the right talent. 
Talent acquisition and retention is supported by 
our ongoing work to enhance our employee 
proposition. Informed by our employee 
engagement survey feedback, and other 
feedback mechanisms, our actions are making 
Senior an even more attractive place to work. 
To that end many of our businesses have 
actively participated in career fairs and other 
activities that highlight the career opportunities 
available, and on a broader level, inspiring the 
engineers of the future. Examples of the steps 
we have taken to enhance our employee value 
proposition include flexible working, promoting 
our employee assistance programmes and 
introducing other support mechanisms such 
as mental health first aiders. We continue to 
be vigilant regarding rates of pay and the cost 
of living, ensuring we are paying people fairly 
for the work they do, and benchmarking pay 
rates in local markets, making adjustments 
if appropriate. 
‘Perform’, our Performance and Development 
system provides a framework for managers and 
team members to discuss feedback, 
performance,behaviours linked directly to our 
Values, set clear objectives, both for business 
and personal development and create 
development plans. In order to enable 
individuals to fulfil their potential, learning and 
development needs are assessed during 
individual performance reviews and the output 
of these discussions feed into our succession 
planning process. For shopfloor operations 
teams, operating businesses undertake 
performance reviews, primarily paper based, to 
enable employees to discuss their performance, 
behaviours and development plans. The 
Executive Committee scrutinises succession 
plans and talent pipeline, identifying successors 
or interim cover for key roles across the Group. 
The Executive Committee also focuses on 
functional capability, for example engineering, 
as well as operational leadership. The Board 
reviews the succession plans for the Executive 
team and their direct reports on a regular basis, 
with a special emphasis on encouraging 
diversity and inclusion. 
Training and development remained a priority in 
2024. Business leaders work with their teams 
and HR to plan and design training to meet 
the business needs of their operation. In our 
autonomous and collaborative operating model, 
operating businesses conduct their own 
training needs analysis and learning and 
development plans, including technical, on the 
job and skills training. We continue to view the 
provision of development opportunities and 
training across the Group as vital to our success. 
As well as partnering with external providers to 
build our bench strength and support 
succession planning, every operation has a 
comprehensive offering of internal training. 
Examples of this include training activities such 
as Toolbox talks; “lunch and learns”; technical 
training; operational excellence, including lean 
manufacturing; as well as sponsoring individuals 
undertaking external and more academically 
orientated courses and training, for example 
engineering degree courses. 
Our leadership programme, Leading for 
Excellence continues to receive positive 
feedback, meeting the development needs of 
our future leaders. The programme runs over six 
months and is a mix of virtual and face-to-face 
sessions as well as one-to-one coaching. The 
programme culminates in the delegates 
presenting business projects they have worked 
on to hone their skills, embed their learning and 
return real business benefits through delivering 
a key project for their operating business. 
‘Learn’, our best-in-class eLearning platform 
allows individuals to self-select training as well 
as being directed to specific content, for 
example following a personal development 
discussion. We have continued to enhance the 
content in Learn. The catalogue covers areas 
such as IT skills, Leadership and Management, 
Project Management, Health & Wellbeing 
and Communication skills, available in all our 
languages. Learn also enables us to deliver our 
Code of Conduct training and other compliance 
training. In 2024, we launched Trade 
Compliance training to US employees, two 
cyber security courses, one for all IS and IT 
teams and one for selected business leaders, 
and an AI training course which all employees 
with emails were asked to complete. We also 
used the platform to launch the in-house 
developed Preventing Workplace Violence 
training to meet the new California legislative 
requirements and, following the new duty under 
the Equality Act 2010 in the UK, all UK 
employees were issued with Preventing Sexual 
Harassment training. 
As in the Global Employee Opinion Survey at 
the end of 2022, peer relationships remained a 
strength in the 2024 survey with a culture where 
colleagues help and support each other. We 
have an open and honest culture of respect and 
trust, and people value teamwork and the teams 
they work in and with. Our businesses have 
onboarding processes to ensure that new team 
members feel welcome and well informed, 
enabling them to become valued team 
members, and in the opinion survey, the 
engagement score for employees with less than 
one year’s service was higher than the overall 
Senior score. A significant proportion of learning 
is on the job and our culture of sharing 
knowledge and supporting colleagues remains 
central to developing technical competencies in 
our operations. 
The culture across Senior is to build on our 
successes and learn from our mistakes. We say 
thank you, with our businesses holding regular 
employee recognition and team building events. 
As well as feedback received via the opinion 
survey, we encourage open and honest 
feedback with potential issues or concerns 
being raised with local management. The 
feedback from the survey was consistent with 
this and confirms that employees believe that 
people are treated fairly and that we do not 
tolerate misconduct. As outlined in our Values 
and Code of Conduct, we work together with 
mutual trust and respect and operate with 
integrity and in an ethical manner. On the rare 
occasion when an employee or employees have 
a concern that cannot be resolved by local 
management, employees are encouraged to 
raise their concerns through our third-party 
whistle-blowing service, EthicsPoint. All 
concerns raised are investigated and learning 
points are actioned by local leadership teams 
as appropriate.

In addition to receiving feedback on how 
engaged our employees feel we also asked a 
series of specific Health and Wellbeing 
questions in the Global Employee Opinion 
Survey. The overall Health and Wellbeing score 
improved by 0.2, taking it to 7.7. In all areas the 
Health and Wellbeing scores improved. 
However, the businesses have not been 
complacent, and many have set actions to 
further improve employee wellbeing. Examples 
include monthly health drives, providing healthy 
snacks, initiatives to improve muscular skeletal 
wellness and subsidised gym memberships. 
Across Senior we provide a range of wellbeing 
support and education to employees as 
appropriate to local needs. Many have 
promoted specific health drives, for example, 
menopause awareness, health checks, flu and 
COVID vaccinations, and road safety education. 
We have a number of individuals specially 
trained to support colleagues with mental health 
issues and employee assistance programmes in 
many of our businesses. One of our larger 
businesses has partnered with a counsellor who 
attends the site on a regular basis to support 
employees, as needed. Other examples of 
how we support employees include offering 
subscriptions to wellbeing apps, creating quiet 
spaces for employees and start-of-shift exercise 
stretching classes. 
Financial wellness is also important for 
wellbeing and businesses have provided 
support in this area as well. In the UK we 
continue to support employees with our 
financial wellbeing service and operations have 
invited benefits providers to our facilities to offer 
information and answer employee’s questions.
Colleagues also enjoy participating in sports 
activities, team building, sports events, and 
family days such as the one held at Senior 
Aerospace Mexico. During this event, 
employees’ families visited our facility to 
get a firsthand look at the environment, 
tour the factory, interact with teams, and learn 
about the processes that contribute to the 
Company´s success. 
We continue to launch new wellbeing content 
on Learn and it goes without saying that we 
remain vigilant regarding occupational health, 
for example ergonomics, supported by our 
Health and Safety frameworks.

Communities
Senior’s businesses actively support local 
communities by undertaking a range of 
education-focused and charitable activities. Here 
are some examples, to name but a few, of the 
activities our businesses and employees have 
undertaken to support their local communities:
A number of our businesses support local food 
banks with Senior Flexonics Canada providing 
freshly grown produce grown by our employees. 
As well as supporting local schools with STEM 
initiatives by sponsoring the STEM club, 
Lymington Precision Engineering (“LPE”) again 
worked with an infant school as part of the 
school’s engineering week. Businesses have 
hosted local trade schools and technical 
colleges, providing an insight into working for 
an engineering company and giving students an 
opportunity to see engineering in action. Senior 
Aerospace SSP supported ReIGNITE HOPE, 
a charity that provides support to help 
disadvantaged individuals, for example 
individuals transitioning from being unhoused 
and/or long-term unemployed to get into work. 
SSP did this by offering placements to 
individuals who received welding training from 
ReIGNITE HOPE. Both Senior Aerospace 
Thailand and Senior Aerospace Malaysia 
employees participated in blood donation drives. 
Senior Aerospace BWT participated in the 
Salvation Army Toy Appeal 2024 and as a result 
of employees’ generosity handed over 150 toys. 
In May 2024, Senior Aerospace Jet & Ketema 
helped raise funds to support Quality of Life 
Programmes for Navy personnel by participating 
in the Navy Bay Bridge 5K Run/Walk and in 
October they participated in the 5K Walk to 
End Alzheimer’s, raising funds to further the 
care, support and research efforts of the 
Alzheimer’s Association.
In August, Cape Town faced severe storms 
and flooding, which tragically impacted some 
of our employees, including the devastating 
loss of their homes. In response, our team 
demonstrated solidarity and compassion by 
coming together to donate food, clothing, 
and toiletries, providing much-needed support 
to help them rebuild their lives. 
In 2024, Senior Metal Bellows continued theit 
participation in HEESCO’s St. Patrick’s 5K. 
Thirty-two employees took part and raised 
money for the charity, with two of the runners 
coming first in their age groups. HESSCO 
provides support and services for individuals 
living with a disability, and their caregivers. 
Senior Aerospace Thailand showed their 
commitment to keeping fit and raising money 
again with 40 runners participating in 
the Pattaya Marathon.
Senior Aerospace Thailand employees participate in blood donations.
Senior Aerospace Jet & Ketema raised funds for the Alzheimer’s Association by participating in the 5K Walk to End Alzheimer’s.

Senior’s Purpose – “We help engineer the 
transition to a sustainable world for the 
benefit of all our stakeholders” – articulates 
our commitment to long-term value 
creation for our stakeholders. We recognise 
that effective governance of sustainability-
related matters is essential to ensure that 
decision-making is aligned with the 
Company’s overarching Purpose. Senior’s 
Executive Committee is responsible for the 
management of sustainability-related 
matters. The Board of Directors has 
oversight over such matters through regular 
updates provided during the scheduled 
Board meetings on the Group’s 
sustainability performance and initiatives.
Uphold high standards of ethical integrity
The Senior plc Code of Conduct (the Code), 
available on the Company’s website, provides 
our employees and business partners with a 
clear framework on which to base decisions 
when conducting day-to-day business. It does 
this by:
•	 clearly setting out the behaviour expected 
of all employees and business partners;
•	 providing guidelines which help employees 
to apply Senior’s Values; and
•	 enabling employees to raise a concern 
or ask a question if in doubt.
The Code contains work-related scenarios, 
together with a selection of questions and 
answers, to help employees understand the 
Code and relate it to their individual roles and 
working environment. All employees are 
expected to follow the Code when performing 
their day-to-day duties, or where they are 
representing Senior.
The 2024 Global Code of Conduct training 
course contained the following modules:
•	 Anti-bribery;
•	 Unconscious Bias;
•	 Promoting the Reporting of Misconduct; and
•	 Social Engineering.
We use different methods to promote 
and ensure compliance with the Code 
across the Group:
•	 All employees are issued with a printed copy 
of the Code, available in all languages 
applicable to the Group employees.
•	 All employees must complete annual Code 
of Conduct training. The Group’s completion 
rate for its 2024 Code of Conduct training 
can be found on page 1.
•	 The Group Chief Executive Officer, Group 
Finance Director and other members of the 
Executive Leadership team reinforce the 
Code and the importance of maintaining 
commitment to the highest ethical standards 
during their regular visits to the Group’s 
operating businesses.
•	 Annual control self assessments, 
encompassing questions related to the Code, 
are conducted across all operating businesses.
•	 Internal audits test compliance with sections 
of the Code and the prominent display of the 
Group’s whistle-blowing procedures at all 
operating businesses.
•	 Risk assessments considering areas of the 
Code are conducted at operating business 
and Group levels. Through its assurance 
programme, the Board is able to ensure that 
employees receive mandatory training and 
that the Group’s operating businesses uphold 
high standards of ethical integrity. All alleged 
violations or complaints are investigated, and 
any remedial actions are taken as necessary. 
Any fraud issues that have come to the 
attention of the Director of Risk and 
Assurance are discussed by the Audit 
Committee, noting the cause, the actions 
taken and any improvements to internal 
controls implemented as a result.
Responsible taxation
Senior’s “Approach to Tax”, which can be found 
on the Company’s website, is aligned with the 
principles set out in the Code, which underpins 
the way we go about our day-to-day business 
across the Group and places integrity and ethical 
behaviour at the heart of what we do. Once a 
year, the Board of Directors approves the 
Group’s tax strategy.
Product safety
Product quality is absolutely core in all of 
Senior’s operating businesses and activities.
All of Senior’s businesses have ISO 9001 
accreditation for manufacturing. The operating 
businesses have additional aerospace and 
automotive accreditations, dependent upon their 
intended markets. Ultimate responsibility for 
product quality and safety lies with the senior 
manager of each business unit. 
All products undergo service/safety risk 
assessments, as required in Senior’s demanding 
markets. Employees receive regular training on 
product and service safety. All the Group’s 
operating businesses have in place incident 
investigation and corrective action policies and 
procedures and quality testing programmes. 
Product/service objectives or targets are set by 
the operating businesses to meet customer 
requirements and regular external product/
service safety audits are conducted, where 
standards require.

STRATEGIC 
PRIORITIES 
OVERALL
The following six 
strategic priorities are 
key elements of our 
Business Model which 
drive the creation of 
stakeholder value. 
Our progress since 
these priorities were 
established is shown 
and they continue 
to receive specific 
attention and focus.
Autonomous and collaborative 
business model
Focus on growth
Overview
Senior’s Business Model is one of empowering and holding 
accountable our operating businesses, operating within 
a clearly defined control framework. Business plans are 
developed in line with the overall Group strategy. Increasing 
collaboration amongst operating businesses in the Group 
is a priority in order to address our customers’ needs whilst 
maintaining an autonomous business structure. Business 
leaders throughout Senior are actively embracing collaboration 
activities. By utilising this unique differentiator, Senior in 2024 
was able to showcase our competitive advantage:
•	 Secured a significant new nomination with a major 
European Truck manufacturer for EGR tubes. Product 
development is being undertaken at our design centre 
in Crumlin, Wales with production at our Olomouc, the 
Czech Republic and Saltillo, Mexico manufacturing 
sites. This collaborative effort is ensuring we meet 
the accelerated timescale for high volumes required 
by our customer.
•	 Secured and launched a substantial programme with a 
major global Engine Manufacturer to produce engine tubes 
in Europe and China, through collaboration between our 
Olomouc, Wuhan and Crumlin sites. Our customer had an 
urgent need to re-source due to a failure in their existing 
supply chain. Our collaborative approach allowed us to 
start series production in a matter of months.
•	 Designed and built a Vacuum Jacket Hose for a Hydrogen 
Combustion application for a major Aerospace OEM, 
combining cross-divisional expertise in predictive 
engineering, design and prototype in our Crumlin and 
Canada businesses.
•	 We successfully entered the Chinese Off-Highway 
Exhaust Flex market, winning business with major OEMs, 
utilising Crumlin product design and qualification testing 
expertise in collaboration with our Wuhan JV. 
Medium term
We will open our new product design and development 
centre in Crumlin in 2025 following investment in a new, 
larger, state-of-the-art facility. Crumlin’s raison d’être is to 
design and market products which are then manufactured 
in multiple locations around the world. Within the new 
Crumlin site we are establishing production of EV battery 
thermal management plates for established commercial 
vehicle applications. This will enable the launch of future 
projects across our global manufacturing base.
We will develop the next generation of Thermal Management 
products for cleaner Diesel & Hydrogen Combustion engines 
for one of our long-standing OEM customers in the 
Construction Equipment sector. This will involve design 
and development in Crumlin, with production in Senior India.
Working with a major European OEM, we have developed 
a Power Electronics Thermal Management solution for 
a regenerative braking system for use in Rail & Truck 
applications. Development, validation and testing will be 
undertaken in Crumlin, with a manufacturing strategy being 
provided by our Cape Town Manufacturing site.
Through collaboration across our Flexonics & Aerospace 
businesses, we are working as part of a consortium to 
develop a market leading thermal management system to 
manage waste heat generated by an advanced Hydrogen 
Fuel Cell Aerospace Propulsion System.
Governance
The Executive Committee and the Board regularly review 
the organisational design of the Group to ensure it is aligned 
to our strategic plan.
Overview
Senior operates in end markets with structural long-term 
growth drivers. We aim to consistently outgrow our end 
markets by:
•	 growing market share, particularly with key customers;
•	 focusing on technology and product innovation;
•	 geographical expansion; and
•	 exploiting adjacent opportunities organically 
and through acquisition.
Aerospace
A key focus over the next five years will be to establish Senior 
as a major supplier of fluid conveyance standards-compliant 
highly engineered parts including fittings, flanges, clamps 
and couplings. There is significant demand for these products 
from our existing customer base. The acquisition of Spencer 
Aerospace in late 2022 was a key element of this strategy 
and we have also been investing organically in new 
capabilities at our Aerospace businesses in the UK and 
France which has directly led to new customer awards. 
Flexonics
Many of Flexonics’ products are focused on helping 
customers transition to more sustainable solutions in hard 
to decarbonise sectors.
For example, in our land vehicle segments, improved 
efficiency of our current product offering supports our 
customers’ need to meet their carbon reduction targets 
in the near term. Additionally, we have partnered with 
customers in the development of new propulsion 
technologies and are well positioned to participate in this 
critical transition through our thermal management and 
fluid conveyance knowledge, skills and expertise.
Medium term
Given Senior’s aim to broaden end market exposure over 
the medium term, we will continue to grow in the maturing 
Advanced Air Mobility market, while keeping close attention 
to other markets such as emerging military technologies 
and decarbonised propulsion.
Moving forward, our investments in innovation will enable us 
to target other growth areas in energy production, such as 
back-up energy storage and nuclear. Our products are enablers 
to the efficient operation of fuel cells and electrolysers, which 
are key parts of the evolving hydrogen market and energy 
storage market. Our technology also facilitates the introduction 
of small modular reactors, which use passive thermal solutions 
to ensure safe operating temperature. 
We also see an increasing need for our products in other 
markets where demographics and AI will drive growth, 
such as Medical and Semi-Conductor. We have strong 
customer relationships managed collaboratively within 
Flexonics and more broadly across Senior into these 
ever-growing markets, and we see them as areas of 
continued growth in the near term.
Governance
Growth opportunities are regularly reviewed by the Executive 
Committee and Board. The Technology Council is in place 
under the chairmanship of the Executive VP, Strategy, and 
progress on strategic technology and product developments 
are regularly presented to, and discussed by, the Executive 
Committee and the Board. The long-term strategic growth 
plan is evaluated at the annual Board Strategy Review and 
monitored continuously.

Overview
Senior understands the importance of 
considered and effective capital 
deployment in the interest of 
maximising the creation of shareholder 
value. All significant investments and 
portfolio changes, including M&A  
and Prune to Grow, undertaken by 
Senior are assessed using a rigorous 
investment appraisal process and  
are supported by a business case. 
In 2024, we maintained our pricing  
and return on capital discipline when 
negotiating contracts and assessing 
investments. Key investment  
approvals include:
•	 Investing in a new, larger, 
state-of-the-art facility for our 
product design and development 
centre in Crumlin, including 
investment in setting up production 
of EV battery thermal management 
plates for established commercial 
vehicle applications. This will enable 
the launch of future projects across 
our global manufacturing base.
•	 Doubling the capacity of our 
Olomouc, Czech Republic facility, 
having won new contracts with 
European truck and passenger 
vehicles OEMs to supply EGR and 
engine tubes for multiple platforms.
We propose to grow the dividend in 
respect of the full year (total paid and 
proposed) by 4%.
We continued to actively manage the 
portfolio by reviewing our operating 
businesses and evaluating them in 
terms of strategic fit within the Group.
Medium term
Senior understands the importance  
of considered and effective capital

The Group is highly focused on 
delivering excellent overall return on 
capital employed which is well in 
excess of the Group’s cost of capital.
We aim to continue to increase the 
Group’s ROCE and to drive working 
capital efficiencies at all operations  
in the medium term.
Governance
The Board regularly reviews the 
Group’s portfolio to ensure that 
long-term value is being generated for 
shareholders. Where appropriate, 
divestments will be considered. M&A 
opportunities are evaluated and 
discussed at each meeting of the M&A 
Committee, as appropriate, and the 
overall M&A and Prune To Grow 
divestment strategies are reviewed at 
the Board Strategy Review. Active 
projects are also discussed at each 
Board meeting as appropriate.
Overview
Senior strives for excellence through  
a high-performance operating model, 
drawing on the many world-class 
practices from across the Group.  
The key elements include:
•	 the Senior Operating System (SOS): 
an operational toolkit incorporating 
best practice processes such as 
lean and continuous improvement 
techniques, supplier management, 
new product introduction, 5/6S 
methodology, factory visual 
management systems, and risk  
and financial management;
•	 a comprehensive business review 
process utilising a balanced 
scorecard incorporating KPIs with  
a focus on performance, growth, 
operational excellence and talent 
development; and
•	 clear processes for developing 
strategy, ensuring top-down and 
bottom-up alignment, considering 
inorganic investments and managing 
M&A transactions. 
Throughout the year we have 
continued to conduct multiple lean 
events in both divisions, always with 
continuing focus on cycle time 
reduction and cost reduction, together 
with continued targeted inventory 
improvement workshops. Following a 
retirement, we have recruited a new 
Senior Vice President for Operational 
Excellence who is actively engaged in 
driving best practices across our 
operations, working hand in hand with 
the lean champions in our operating 
businesses. Continued to drive Kaizen 
events in both divisions, aimed at 
inventory management, cycle time 
reduction and cost reduction. We have 
also rolled out formal A3 thinking 
training across the business and hosted 
monthly meetings of the Aerospace 
Lean Council to foster collaboration  
and share best practices. 
Medium term
Moving forward we aim to  
strengthen and develop the SOS  
in the following areas:
•	 Inventory Reduction: Focus on 
inventory reduction through  
strategy deployment, A3 thinking, 
and Kaizen events.
•	 Strategic Plan Deployment: Cascade 
the strategic plan throughout the 
organisation by deploying and 
executing the X-Matrix and continue 
embedding A3 thinking deeper into 
the organisation.
•	 Reinvigorate the Operating System: 
Introduce a formal roadmap  
for continuous improvement 
success and conduct a cultural 
maturity assessment.
•	 Kaizen events: Increase both  
the pace and quality of Kaizen 
events across all sites.
Governance
Our Vice President of Operational 
Excellence chairs the Aerospace  
Lean Council on a monthly basis.  
The Executive Committee reviews 
operational performance and the  
Group CEO reports progress to the 
Board at every Board meeting.
Overview
Senior’s global footprint ensures that 
our operating businesses stay 
competitive at both a capability and 
cost level. Key investments have been 
made in Thailand, Malaysia, China, 
India, Mexico, South Africa, and the 
Czech Republic to help ensure we 
meet our customers’ cost and price 
challenges whilst enhancing returns on 
investment. We have established 
increasingly sophisticated capabilities 
in these competitive cost countries and 
optimised production capacity to align 
with growing demand.
Over the last year, we won new 
business and launched production 
programmes in India, China, Czech 
Republic and Cape Town. We 
continued the transfer of fluid 
conveyance products to our Saltillo 
aerospace manufacturing site from 
California for cost and capacity 
reasons: this will continue in 2025.  
In India we will open a new factory 
(while exiting an older, smaller facility) 
that will provide much needed 
additional capacity to meet higher 
demand from new business awards.
Medium term
Looking to the future we aim to  
extend this model further, with sites 
such as Cape Town in South Africa  
not just serving the local market but 
increasingly working with other 
businesses to serve customers across 
Europe and potentially in the US.  
Our cost competitive locations will 
continue to play a key role in meeting 
our customers’ global requirements 
while providing attractive returns  
for shareholders.
Governance 
The Executive Committee conducts 
quarterly Business Reviews of all 
operations. The Group Chief Executive 
Officer and Group Finance Director 
report and discuss progress at each 
Board meeting. The overall progress  
of the competitive cost country 
strategy is reviewed at the Board 
Strategy Review on a regular basis.
Overview
Senior has a highly skilled workforce, 
experienced entrepreneurial business 
leaders and functional experts. We aim 
to attract and develop talent, supporting 
employees with online tools to enable 
personal and skills development as well 
as comprehensive technical and 
operational training. The Group has a 
strong focus on diversity and inclusion 
across the business including on our 
Board and Executive team. 
Attracting, retaining and developing 
talent remains key and we have 
embedded processes and systems  
to help achieve this. This includes:
•	 global succession planning process;
•	 online talent acquisition system in 
the UK and US with future plans to 
roll out globally; 
•	 Perform, our global Performance 
and Development system; 
•	 Learn, our global online learning 
platform; and
•	 Senior Employee Opinion Survey, 
now run annually, which enables us 
to look at populations of employees 
such as Engineering to ensure that 
they are engaged and motivated.
Medium term
Our operating businesses focus on 
developing engineering talent to  
support our strategic plans. To that end, 
we collaborate with universities and 
technology colleges and other relevant 
organisations. Individuals are supported 
with training such as Masters degrees 
as well as apprenticeships and 
certifications. Looking forward we  
plan to enhance our training 
programmes and provide career paths 
for key functional areas such as research 
and development engineers.
To help achieve our growth targets we 
will invest in business development 
and design and applications 
engineering talent, in particular these 
teams will be focused on utilising their 
skills and knowledge in order to 
develop products for new markets. 
Senior operates a number of 
successful apprentice schemes, or 
equivalent, which is a proven route for 
successfully developing careers within 
Senior. Our annual succession planning 
process enables us to identify talent 
and ensure we have appropriate plans 
for every key role in the Company.
Governance 
The Executive Committee conducts  
an extensive review of operating 
businesses’ leadership succession 
plans. As stated above, the review 
scrutinises our talent pipeline, 
identifying successors or interim cover 
for key roles across our businesses. 
Appropriate development plans are  
in place and recorded in Perform,  
our performance management system, 
to enable individuals to fulfil their 
potential. The Board formally reviews 
the succession plans for the Executive 
team bi-annually and their direct

TECHNOLOGY
Fluid conveyance and thermal management
Case study
HYDROGEN
As previously mentioned, hydrogen 
usage is often managed at very high 
pressure. At our Senior Flexonics 
Kassel business in Germany, our fluid 
conveyance hose technology has 
been significantly enhanced to endure 
pressures of over 1000 times that 
of the atmosphere. Products in current 
mainstream series production are
already capable of 300 times 
atmospheric pressure however – in many 
applications – this is not sufficient to 
cater for conveying gaseous hydrogen. 
Working from today’s known technology, 
the core components of the hose have 
been significantly adapted to endure the 
higher pressure. A number of design 
iterations had been investigated with the 
final design concept undergoing rigorous 
material and pressure test validation.
The design solution, which is capable of 
enduring up to 750 times atmospheric 
pressure – with safety factor on top – has 
fully completed the validation process 
and achieved accreditation through the 
well respected and recognised body TÜV 
SÜD. Orders have already been secured 
for the product and have been supplied 
to a number of customers who are 
needing to either store, transport or 
dispense gaseous hydrogen. 
The further enhanced design solution 
capable of enduring more than 1000 
times that of atmospheric pressure – still 
with a safety factor – is currently midway 
through the validation process which will 
continue throughout the course of 2025. 
This product will also go through the 
same accreditation process. 
Our hydrogen hoses have been designed to withstand 
750 times atmospheric pressure.
Our technology themes
Within both Aerospace and Flexonics 
Divisions our core technologies are fluid 
conveyance and thermal management 
components or systems. Legislation is driving 
reduced emissions with the ultimate end goal 
of achieving net zero, and so to meet 
changing customer requirements we 
have responded by evolving our current 
products as well as developing IP-rich, 
innovative technologies.
In order to de-carbonise, the land vehicle 
market is set to rely heavily on electrification, 
and this in turn leads to a significant 
requirement for battery cooling. Our fluid 
conveyance products and systems route the 
coolant from the reservoir to where it is 
needed at the battery. Our design engineers 
work with the customer to ensure criteria 
such as package space, weight and durability 
targets are met. In some instances – we are 
currently working with a major European 
truck OEM – the geometry can become 
incredibly complex, but this is not an issue 
as our highly automated manufacturing 
processes such as the one at our Senior 
Flexonics Olomouc business in the Czech 
Republic are able to adapt and deliver 
a world class quality product. 
One of the headwinds facing the adoption 
of electric vehicles is the availability of 
electricity generated from green renewal 
sources. In this area Senior Flexonics Pathway 
is supporting a company called Malta with 
their highly innovative energy storage system 
which converts electricity to thermal energy 
then storing it using molten salt ready for 
re-converting back to electricity when 
demand requires. Senior Pathway are 
supplying expansion joints which alleviate 
the stresses within the system caused by the 
thermal loading. Product has been supplied, 
and evaluation trials are being conducted. 
In all markets, hydrogen is set to play a key 
role in how we get to net zero. Whether it be 
in gaseous or liquid state, our products are 
being enhanced to convey this matter safely. 
Our Senior Aerospace Calorstat business in 
France is leading the way in the development 
and supply of bellows that will support the 
use of liquid hydrogen at a cryogenic 
temperature of -253 deg C. Working closely 
with a major aerospace OEM, this work 
requires investigating new material options 
and pioneering techniques to allow the 
welding of two fundamentally different 
materials to achieve cryogenic operation.

HEAT EXCHANGERS 
In terms of thermal management, another 
example of Senior breaking new ground 
is the heat exchanger product we are 
developing for a major power 
management OEM. As part of a US 
Department of Energy project and in 
collaboration with Purdue University, the 
OEM will use their compressor 
technology to extend the life of the 
hydrogen fuel cell system, which drives 
a requirement for an Air-to Air Recuperator 
to achieve this. Using bend-a-flex 
technology inside a Shell and Tube 
configuration, our Senior Flexonics Bartlett 
business in Chicago, IL. has developed 
an IP rich heat exchanger to meet the 
performance needs. At 36 litres capacity 
and approximately 5 times larger than any 
similar design in current production, our 
core technology is proving suitably 
scalable to meet the required needs. 
The product has been successfully 
manufactured at prototype volumes. 
An extensive performance and durability 
testing program at Senior is already 
underway. Samples have also been 
delivered to the OEM with system trials to 
be conducted during the course of 2025.
Our IP-rich heat exchanger extends the in-service life 
of hydrogen fuel cell systems.

The usage of hydrogen creates many 
engineering challenges including 
management of cryogenic temperatures and 
very high pressures. To meet the needs of the 
Heavy Duty Truck market utilising hydrogen 
internal combustion powertrain technology, 
at our Senior Flexonics Crumlin research 
centre in the UK we are currently developing 
a heat exchanger that will withstand up to 
400 times atmospheric pressure plus an 
additional safety factor. Having been evolved 
from current know-how, the design concept 
has now been completed and is ready to 
go into prototype sample production. 
Thereafter, an extensive testing and validation 
programme will be undertaken eventually 
culminating in accreditation by the relevant 
bodies. To ensure weight, package space 
and performance targets are met, Senior is 
working closely with the relevant Heavy Duty 
Truck OEM. Serial production is anticipated by 
2030 and to reach mature annual volumes by 
the middle of the next decade.
Not only hydrogen but electrification 
challenges require us to evolve our thermal 
management capabilities. During the course 
of 2024, cooling plate design and 
manufacturing processes have been further 
developed. The use of thinner gauge 
materials is being adopted, allowing us to 
achieve ever more complex geometrical 
shapes and profiles, and in turn to achieve 
higher levels of heat transfer efficiency. 
End user applications are becoming more 
diverse, with our expertise being widely 
adopted in the land vehicle market from 
motorcycles to buses and trucks with the 
latter requiring dimensionally larger scale 
cooling plates. As we increase our customer 
portfolio and annual production volumes of 
the cooling plates – at our new facility in 
Senior Flexonics, Crumlin – investment is 
being made in the form a semi-continuous 
brazing line.

OPTIMIZING AEROSPACE 
HOT FORMING 
Our Senior Aerospace Thermal 
Engineering business in the UK, using 
Autoform Metal Forming simulation 
software, have developed the capability 
to predict material behaviour digitally 
during both cold and hot sheet metal 
forming processes.
Work to refine our modelling parameters 
and material characteristic data over 
recent years is now reaping benefits 
following multiple work package awards 
providing confidence to customers that 
our forming process will yield conforming 
parts. Through the last year, Senior 
Aerospace Thermal Engineering has 
proven several ‘right first time’ tool 
try-outs. Traditionally, multiple iterations 
are required to perfect the press tool, 
blank size and press operating 
parameters. The new simulation process 
has reduced New Product Introduction 
lead-times by up to 8 weeks and, 
significantly, provides inputs to the 
customer’s design which means Senior 
Aerospace Thermal Engineering will be 
able to manufacture defect-free parts 
without the need for expensive dressing, 
trimming or corrections. 
Vacuum Jacketed Hose 
Lead times for complex product introductions have been 
significantly reduced using simulation software.
To store more hydrogen for any given volume 
of space, the gas is compressed to a liquid 
form resulting in a temperature of -253 deg C. 
When liquid hydrogen is being transferred from 
one place to another it must remain at this 
temperature to stay in liquid form. Our Senior 
Flexonics businesses in Canada and Germany 
have flexible hoses that are dual wall with both 
a vacuum and insulating material between the 
two walls of the hose. Known as a Vacuum 
Jacketed Hose, these features ensure that any 
matter passing through the hose will maintain 
the same temperature from inlet to outlet. The 
underlying technology has been adapted and 
enhanced to meet the needs of hydrogen.
Among the customers we are collaborating 
with is a major engine supplier who in 
mid-2025 will run a hydrogen fuelled turbo-fan 
demonstrator engine at NASA’s Stennis Space 
Centre. This groundbreaking demonstrator is 
based on an existing engine, modified to 
combust hydrogen fuel, which includes the 
Senior Vacuum Jacketed Hose. 
With input and support from Senior, the 
customer developed the technical specification. 
Senior then employed its know-how and 
experience from a number of sites – to 
generate a design solution. Working 
collaboratively, our Senior Aerospace Bird 
Bellows, Senior Flexonics Crumlin and Senior 
Flexonics Canada businesses are undertaking 
the initial design, feasibility study, extensive 
durability simulation, testing and manufacture 
to deliver the product on time. Throughout the 
test schedule of the demonstrator programme, 
the component will undergo a number of 
differing input loads such as extreme 
temperatures, varying pressures and alternating 
engine vibrations all of which have to be taken 
into account when initially designing the 
product. We will then simulate based on our 
Finite Element Analysis modelling software 
to ensure the component is fit for purpose. 
The hydrogen demonstrator engine 
programme will have a further phase requiring 
additional technology. For Senior, this has 
several implications and challenges among 
them being the requirement for a leak 
detection system. The safety critical nature of 
this product means leak detection is crucial a 
must but at present no suitable system exists. 
Senior is actively engaging with Aerospace 
Technology Institute (ATI) in the UK who – in 
order to support their Fly Zero project – have 
a number of open funding calls. Senior will 
collaborate with partners who have the 
appropriate expertise to create a leak 
In support of our core technology themes, 
Senior continues to progress innovation 
throughout our product development 
and manufacturing lifecycle. 
Ongoing engagement through our company-
wide Technology Council ensures that these 
technologies are collaboratively promoted  
and developed across the Group to ensure  
that we provide safe and innovative products for 
applications in the most hostile environments.
detection system potentially with ATI 
funding support.
The Vacuum Jacket Hose design is also very 
flexible. At our Senior Aerospace Ermeto 
business in France we are developing dual 
wall vacuum jacket rigid pipes and 
associated dual wall connectors. This will 
allow Senior to provide the customer with 
a complete dual wall vacuum jacketed fluid 
conveyance system comprising a continuous 
route of rigid and flexible sections to carry 
the liquid hydrogen to where it is needed.
Other hydrogen products or projects 
We have previously detailed how we are 
adapting our technology or innovating 
products to meet the storage or usage 
needs of hydrogen. Beyond this, there is 
content for Senior throughout the value chain 
including in the manufacture of green 
hydrogen through the process of electrolysis. 
The electrolysers used in this process 
require both thermal management and fluid 
conveyance products and through 
collaboration between our Senior Flexonics 
Bartlett and Senior Flexonics Canada 
businesses we can now offer Pipe Spooling 
fluid conveyance components, which carry 
hydrogen through all areas of the electrolyser 
unit. Our highly skilled manual welding 
expertise has been developed in order to 
meet the stringent tolerances required by 
the electrolyser manufacturers. 
Whilst the need for green hydrogen and its 
usage in the maritime and land vehicle 
sectors is now a very real prospect, its 
usage in the aerospace sector – particularly 
via fuel cells - is much longer term. 
However, in order to overcome feasibility 
challenges and gain the relevant flight 
certification in readiness for 2050, work to 
support the aerospace market needs is 
being initiated now. 
There are several consortia led projects 
running within Europe which are targeting 
single-aisle narrow-body flight using 
hydrogen fuel cells. Senior is a member of 
the Dutch Government funded Hydrogen 
Aircraft Powertrain and Storage System 
(HAPSS) consortium not only responsible for 
delivery of the thermal management system 
but also participating in the project steering 
committee. This project is truly pioneering, 
it will push boundaries and take our fluid 
conveyance and thermal management 
technical know-how to new levels aiming for 
revolutionary zero emissions regional flight.

METALLIC ADDITIVE 
MANUFACTURING FOR 
AERO ENGINES 
Our Advanced Additive Manufacturing 
Centre at Senior Aerospace SSP in 
Burbank, CA is engaged with a major aero 
engine OEM for the supply of a variety 
of 3D printed metallic helicopter engine 
components. Owing to acute supply-chain 
delivery and cost challenges, our 
customer wanted to qualify a new 
supply-chain and manufacturing process. 
In some cases, our additive manufacturing 
process eliminates 12-month casting 
lead-times, providing a more agile 
response operationally and will also 
deliver important unit cost savings to the 
customer. During 2025, after a 3-year 
journey in which prototype parts have 
been supplied, we will receive material 
qualification to enable serial production 
to begin in early 2026, displacing the 
incumbent supply-chain. Our NADCAP 
approved additive manufacturing facility 
has a very high level of vertical integration 
leading to the highest quality service 
and responsiveness to support customer 
programmes. The products are engine 
structures and ducts on existing helicopter 
platforms enabling Senior to benefit from 
production rate volumes immediately.
Additive Manufacturing
Additive manufacturing delivers lower cost, less 
weight and a shorter development time for complex 
aero-engine components.
Our focus on investigating new manufacturing 
processes as well as new products has 
continued. A key advancement in recent years 
is additive manufacturing. Senior has invested 
in this technology area and now has two 
centres of excellence – at our Senior 
Aerospace SSP business in California and at 
our Senior Aerospace BWT business in the 
UK. SSP are focused on metallic structures 
whilst BWT composite thermo-plastic. 
The key advantages of additive manufacturing 
are zero tooling cost, short manufacturing 
lead times and almost limitless design 
complexity – the process is ideal for prototype 
or annual low volume rates. Taking advantage 
of this, at Senior Aerospace SSP, we are 
working with a number of the Aerospace 
OEMs and have supplied components such as 
complex ducting, brackets and struts. Being a 
full-service supplier our team of engineers will 
not only design and manufacture the product 
but also will have the facilities and expertise to 
complete the testing and validation followed 
by microstructure characterisation with 
powder and chemical analysis. Our business 
Senior Aerospace SSP is one of the very few 
additive manufacturing companies worldwide 
to have gained NADCAP accreditation. 
Meanwhile Senior Aerospace BWT is 
leveraging its additive manufacturing 
capabilities to replace traditional metallic 
components used in ultra-light-weight 
low-pressure ducts with advanced 
alternatives. Thermoplastics are particularly 
suited for aerospace applications due to their 
exceptional strength-to-weight ratio, heat 
resistance, and chemical stability. Our fully 
aerospace-qualified process is already 
delivering thousands of flight-ready 
components, demonstrating its reliability 
and efficiency. This innovative approach 
helps our customers save costs while 
ensuring exceptional quality with every part 
we produce. Our highly dependable process 
maintains perfect precision and consistency 
while significantly reducing lead times, 
enabling us to offer our customers superior 
products faster and more efficiently.

How we engage
We continue to place a strong emphasis on 
employee engagement with open lines of 
communication and encouraging a culture of 
feedback. To that end, in May 2024, we invited 
all our employees to participate in our Global 
Employee Opinion Survey. 85% of our 
employees completed the survey which is an 
excellent result considering that approximately 
60% of our employees do not have ready 
access to business emails. We were pleased by 
the participation level as this is a sign of positive 
engagement, and that we have created a culture 
where employees are happy to provide 
feedback. Following the survey, business 
leaders and HR teams analysed the results 
for their operation and worked with colleagues 
to develop action plans for their areas of 
responsibility. Every operating business 
communicated the results to their employees 
and shared action plans. In the 2024 survey, we 
asked for feedback on our Purpose – “How do 
you feel about Senior’s Purpose which is to 
‘Help engineer the transition to a sustainable 
world for the benefit of all our stakeholders’?”. 
This provided us with additional insights, and in 
the main employees are supportive and think 
the Purpose makes sense, with comments such 
as feeling proud to be part of an organisation 
that prioritises sustainability, that the Purpose 
is impactful, and that Senior is doing a great job 
engineering new solutions to problems. One 
valuable piece of feedback was that in relation 
to the Purpose, some employees did not view 
themselves as stakeholders, an area for us to 
provide further communication on. See People 
and Culture on page 28 for further information 
on the engagement survey.
While the Employee Opinion Survey is 
a valuable tool in assessing employee 
engagement, our operations recognise the 
importance of maintaining lines of 
communication and making sure employees 
have the appropriate mechanisms in place for 
making suggestions and raising concerns, both 
formally and informally. Business leaders 
continued their regular cadences of holding 
face-to-face, all-hands briefings and team 
meetings. As in previous years, the Executive 
Leadership team visited operating businesses 
for our annual “Employee Roadshows”. 
The Roadshows provide an opportunity for 
members of the Executive Committee to 
present Senior’s business strategy and 
performance, health & safety, sustainability, 
cybersecurity and employee survey feedback. 
Operating business leaders also present 
information related to their individual business, 
for example their local business strategy, 
business performance metrics, product 
development and customer wins. During the 
sessions employees are encouraged to ask 
questions, raise concerns and provide feedback.
Operating businesses also utilised other 
methodologies to engage with employees 
face-to-face such as team meetings, question 
and answer sessions, skip level meetings and 
employee focus groups. We also used tried and 
tested methods like newsletters and meeting 
with employee representative bodies such as 
works councils and unions, and increased our 
use of technology, for example employee apps 
and TV information screens. In 2024, a number 
of our businesses launched or enhanced 
employee apps which are particularly useful in 
providing information to employees who do not 
have easy access to a company computer.
Mary Waldner, the non-executive Director for 
employee engagement and Jane Johnston, 
Group HR Director have continued their 
programme of face-to-face focus groups. 
In addition, Mary has met delegates from our 
Leading for Excellence group development 
programme, met leadership teams when 
visiting sites and joined the monthly global 
HR calls in June. 
Outcome of engagement
All our operating businesses communicated the 
outcome of the Employee Opinion Survey to 
their teams and developed action plans as a 
result of the feedback. The survey provides 
valuable insights at an operating business level 
allowing leaders, in our collaborative and 
autonomous model, to develop meaningful 
actions for their operations. 
The employee engagement score improved 
from 7.2 in the prior survey in October 2022 to 
7.5 in June 2024, and we have received positive 
feedback on many of the actions taken by the 
operations as a result of the 2022 and 2024 
survey feedback. We remain focused on 
communicating the actions we have taken 
and the impact of those actions – “You said, 
we did”. In addition, we have seen an ongoing 
trend of improvements in employee turnover.
Company actions responding 
to engagement outcome 
Management-level actions
Operating business action plans were developed 
following the 2024 Global Employee Opinion 
Survey. The Executive Committee monitors 
performance and receives regular updates 
regarding employee engagement actions and 
progress against the plans throughout the year 
via our formal business review process. There 
has been a notable improvement from previous 
surveys in how operating business leaders 
communicate their strategy to their teams as 
this is no longer indicated as an area for 
improvement. However, business leaders will 
continue to focus on communicating their 
strategy and mission to their teams and thereby 
enabling people to feel inspired and connected 
to business challenges and achievements. 
The next Global Employee Opinion Survey will 
be in May 2025.
Following every focus group, the Group HR 
Director provides feedback to the operating 
business leader and HR lead, linking it to the 
Employee Opinion Survey feedback and making 
recommendations for areas of improvement 
and/or further investigation. The operating 
business leaders implement actions as 
appropriate including explaining why something 
cannot be actioned.
Board-level actions
As referenced above, Mary Waldner engaged 
with employees in a number of ways throughout 
the year. These interactions provided Mary with 
an opportunity to understand more about 
Senior’s culture, and in relation to the HR calls, 
to gain a better understanding regarding the 
people priorities being worked on around the 
Group. The focus groups and other interactions 
afford an opportunity to engage directly with a 
cross section of employees, allowing them to 
ask questions and provide feedback. As always, 
all the discussions were positive, enthusiastic 
and interactive. 
The Board reviewed the 2024 Global Employee 
Opinion Survey action plans and received 
regular updates on employee engagement 
from Jane Johnston, the Group HR Director 
and Mary Waldner, who spent time conducting 
a more in-depth review into the survey data 
points and feedback.

Case study
SENIOR AEROSPACE UPECA AND DHL CONTRIBUTE 
TO MORE SUSTAINABLE AIR FREIGHT WITH SAF 
Senior Aerospace UPECA signed an 
agreement with DHL Express for the use of 
the GoGreen Plus service. The partnership 
enables UPECA to invest in sustainable 
aviation fuel (SAF) to drive up to 30 percent 
reduction in carbon emissions associated with 
their time-definite international shipments. 
GoGreen Plus currently stands as the sole 
solution within the global express logistics 
sector that allows customers to leverage SAF 
towards their Scope 3 footprint, which refers 
to the indirect release of greenhouse gases 
within a company’s supply chain activities. 
Made from alternative raw materials such as 
used cooking oil, waste, and hydrogen, SAF 
cuts around 80 percent of lifecycle carbon 
emissions from air transport compared to 
conventional jet fuel. 
UPECA’s subscription to GoGreen Plus 
applies across its overseas trade lanes, 
encompassing key markets in Europe and 
North America. It comes amidst a report by 
the International Energy Agency that aviation 
has grown faster in recent decades than rail, 
road, and sea transport as a source of 
worldwide CO2e emissions1. The trend 
emphasises the urgency for the upscale and 
uptake of SAF in order to meet the 
International Air Transport Association (IATA) 
target of comprising 50 percent of global 
aviation fuel consumption by 2050. 
“At UPECA, we believe SAF is one of the 
most promising means of decarbonising 
long-haul flight,” said Kavan Jeet Singh, 
Chief Executive Officer of UPECA. 
“Ready for deployment in existing aircraft, 
it complements intensive efforts to transform 
aviation into a post-carbon industry. We are 
delighted to join DHL Express in helping 
contribute to a commercially-viable market 
for such renewable energies.”
“SAF is an important lever for achieving 
cleaner air mobility, but there remains 
progress to be made on the production 
and adoption fronts. Having UPECA onboard 
demonstrates an increasing shift among 
businesses to explore innovative pathways 
for a green transition in their operations. 
These collaborations are essential as we 
continue to promote SAF accessibility and 
affordability at the pace needed to address 
current climate challenges,” said Julian Neo, 
Managing Director of DHL Express Malaysia 
and Brunei.

How we engage
Across Senior, we continue our ongoing 
dialogue with our customers, including at an 
operating business, Division, Group and senior 
management level. Our division-level Customer 
Relationship Managers and Global Marketing 
Teams, in place in Europe, the UK, and the USA, 
interact with and support all levels of our largest 
customers. This process ensures that we 
monitor and understand the fundamental 
dynamics impacting our businesses and their 
end markets. Our ability to have regular and 
cross-functional insights allows us to respond 
appropriately when issues arise and to quickly 
capitalise on opportunities across the whole 
Group. These interactions provide the 
information necessary for Senior to develop 
strategies that link up with our customers’ 
advanced engineering teams to improve costs, 
efficiency, and the achievement of their 
sustainability goals, including the transition to 
a low-carbon economy, their new competitive 
offerings to the marketplace, and mutual 
investments in research and technology.
Feedback is actively sought from our customers 
via frequent interactions between our operating 
business’s customer account and business 
development teams. This involves monthly 
reporting of activities and monitoring of 
our Key Performance Indicators (KPI) and 
customer scorecards across Senior’s operating 
businesses. Whilst Senior regularly receives 
customer awards for operational excellence, 
in those cases where our performance falls 
short of expectations, we actively engage with 
the customer to agree improvement targets, 
implementation schedules, resource dedication, 
and executive involvement. 
We continued to conduct regular senior 
management meetings, including at CEO level, 
with our major customers in 2024. These 
interactions centred around ensuring 
commercial terms reflect current day pricing, 
supply chain and labour issues, operational 
metrics, communications, growth strategies, 
and market dynamics. These executive-level 
meetings formed a vital part of our ongoing 
relationship management and helped to clarify 
and focus our mutual activities towards driving 
success for both Senior and its customers.

STRATEGIC  
REPORT

How we engage
We engage with our suppliers in a variety 
of ways, including during tender and bid 
processes, scheduled status updates, on-site 
visits and audits where appropriate. Supply 
chain constraints continued to ease in 2024 
but the Group remained focused on managing 
stubborn pockets of supply volatility caused by 
material shortages and labour disruption through 
bilateral, collaborative communication and close 
co-ordination with suppliers regarding lead 
times, demand changes, transportation options 
and other sources of volatility. 2024 also 
resulted in a moderation of inflation rates in 
many of the regions in which the Group 
operates and as a result, we recommenced 
discussions with key suppliers regarding 
potential cost reductions as part of our 
ongoing strategic review of supplier price 
competitiveness. The Executive Committee 
continues to closely monitor the health and 
performance of critical Group suppliers and 
supports the operating businesses in their 
engagement with suppliers where necessary. 
In line with our Contract Review Policy, which 
is mandatory for all operating businesses, we 
continue to communicate the requirements of 
the Group’s Sustainable Sourcing Policy to key 
suppliers and provide feedback to our suppliers 
on their performance and, where necessary, 
will agree improvement action plans.
The Group also completes bi-annual reporting 
pursuant to The Reporting on Payment 
Practices and Performance Regulations (2017), 
demonstrating our commitment to remain 
a strong financial partner with our suppliers. 
For Scope 3 Greenhouse Gas emissions, Senior 
has a commitment that 82% of its suppliers by 
spend, covering purchased goods and services 
and capital goods, will have Science Based 
Targets by 2025. 
Outcome of engagement
During 2024, our collaboration with suppliers 
enabled the operating businesses to continue 
to mitigate residual supply chain volatility 
through lead time management, order flexibility 
and other cooperative solutions. We also 
benefited from lower costs on certain material 
and component inputs resulting from successful 
price reduction negotiations with suppliers. 
As part of CDP’s supply chain engagement 
programme, we identified and engaged with 
over 300 suppliers in 2024, reinforcing our 
commitment to driving sustainability throughout 
our value chain. Additionally, we initiated an 
analysis of carbon reduction commitments 
among suppliers not yet participating in the 
CDP process.
Our combined efforts through CDP engagement 
and ongoing analysis have so far revealed that 91 
of our key suppliers have already set carbon 
reduction targets. To support those yet to embark 
on this journey, we have developed a simple 
carbon target tool aligned with the principles of 
science-based targets. This tool provides practical 
guidance to help suppliers establish and 
implement their carbon reduction goals.
Senior’s leadership in supplier engagement 
has been recognised with the highest CDP 
leadership status for supplier engagement in 
both 2022 and 2023. Building on this foundation, 
we will continue advancing this programme 
in 2025, ensuring we drive impactful 
and collaborative climate action across 
our supply chain.
Company actions responding 
to engagement outcome
Management-level actions
Supply chain challenges remained a principle 
risk to the Group in 2024. The Aerospace supply 
chain continued to stabilise, with the volume 
of parts shortages and specific supply chain 
challenges continuing to subside. Where supply 
chain challenges persist, these challenges, 
and actions to address them, continued to be 
focal points during operating business reviews 
and Executive Committee meetings throughout 
the year. 
We continued to engage with our largest 
suppliers on our Scope 3 greenhouse gas 
emission targets and regular updates are 
provided to the Board on progress.
Board-level actions
The Board reviews the bi-annual reports for 
our UK subsidiaries to monitor compliance

Throughout the year we responded to 
requests from investors and analysts for
further information and addressed any 
questions or concerns. 
The Group typically makes constructive use 
of the Annual General Meeting (“AGM”) to 
communicate with its private shareholders, 
whose engagement we value. Held in April 
2024, this forum provided private shareholders 
with the opportunity to hear directly from the 
Group Chief Executive Officer about the 
performance of the business, to submit 
questions to the Directors and to listen 
to their responses. 
Barbara Jeremiah, non-executive Director, 
Senior Independent Director and Chair of the

Trading Update which highlighted short-term 
but temporary headwinds to provide 
reassurance of the Group’s position and 
investment opportunity.
•	 Received better understanding of shareholder 
expectations in respect of strategic decisions.
How we engage
In 2024, the Group continued, both through 
the Executive Leadership team and certain 
members of the Board including the Group 
Chair, to engage with its shareholders 
throughout the year. This was achieved using 
a diverse and tailored range of channels and 
collaterals, which are highlighted below.
Engagement with the Board grew in the year. 
As is customary, the Group’s Chair attended the 
full-year and interim results announcements in 
March and August 2024 and undertook a series 
of solo meetings with the largest shareholders 
to receive feedback on Group strategy, capital 
deployment and allocation, and Senior leadership 
and management. Additionally, the newest 
members of the Board, namely Joe Vorih and 
Zoe Clements, met with the largest shareholders 
for introductory meetings separately.
Below highlights the various ways the Group, 
through its extensive Investor Relations 
programme, engaged with shareholders 
throughout the year: 
•	 twice during the year following the 
announcement of the full-year and interim 
results, the Group Chief Executive Officer, 
Group Finance Director and interim Director 
of Investor Relations & Corporate 
Communications (as the current Director was 
away on maternity leave) engaged with our 
major shareholders through a series of 
face-to-face and virtual meetings (by video 
conference or telephone conference call). 
These meetings centred around the detailed 
performance of the business, the Group’s 
strategic focus on fluid conveyance and 
thermal management capabilities and what 
this means for the future composition and 
portfolio of the business. These meetings 
were used to confirm our understanding of 
our shareholders’ views and address any 
concerns they may have about the Group; 
•	 in addition, we issued two market updates, 
one in April and one in October (followed up 
with a dial-in conference call session for our 
analysts and investors). Furthermore, on each 
occasion, we offered major shareholders the 
opportunity of a follow-up call with the 
Executive Leadership team and Group Chair;
•	 the Group organised one Group investor site 
visit and two sole site visits during the year, 
spanning across France and the East and 
West coast of the US. The Group site visit 
involved visiting two of our French operating 
businesses: Ermeto and Calorstat. The 
management teams of these operating 
businesses hosted institutional shareholders 
and sell-side analysts. The visit showcased 
the fluid conveyance and thermal 
management capabilities of the Group and the 
practical applications of our highly engineered, 
IP-rich, products. The two solo site visits 
involved visiting our Senior Aerospace 
Bartlett, Senior Metal Bellows and Senior 
Flexonics Pathway, and our Senior Aerospace 
Southern California and Senior Aerospace 
Steico businesses;

Company actions responding 
to engagement outcome
Management-level actions
During the course of 2024, engagement with 
shareholders emphasised how focused they are 
on the Group’s overall performance amid the 
existing environment, and in particular, on its 
strategic focus on fluid conveyance and thermal 
management and what that brings from a 
portfolio standpoint. In response to this, we 
continued with our normal Investor Relations 
engagement programme which included 
management presentations, in-person meetings, 
investor site visits and the use of social platforms. 
Investors were able to gain reassurance and 
clarity about Group strategy, understand the 
strategic focus on fluid conveyance and thermal 
management and gain a practical understanding 
of our high-engineered IP-rich capabilities.
Board-level actions
As part of the reporting cycle, the Board gets 
regular reports on the top 20 shareholders, 
movements in the share register, share price 
performance and engagement with investors 
and analysts. These regular investor updates 
included feedback on investor perceptions and 
the financial-market environment. The feedback 
is provided either directly from shareholders, 
from the Group’s Investor Relations function 
or from our corporate brokers, Jefferies and 
Deutsche Numis. Updates from Group-level and 
Board-level engagement with shareholders are 
also provided to the Board as appropriate. 
The Board discusses and considers issues with 
management as part of its decision-making 
process. It also takes the feedback received 
into consideration when reaffirming decisions 
on the Group’s overall strategy and continued 
strategic focus.

Communities
How we engage
Senior takes its responsibility in relation to the 
communities in which we operate seriously, 
striving to nurture good relationships supporting 
local community endeavours, and finding ways 
to engage and make a positive contribution, as 
well as providing employment. Examples of our 
community engagement programmes include:
•	 Senior Aerospace Thailand (“SAT”) supports 
a number of education focused initiatives and 
in 2024 signed an MOU with the Suranaree 
University of Technology. The aim of the 
partnership is to inspire the next generation 
of aerospace engineers. Our Thailand 
operation also hosted a number of educational 
focussed events, for example welcoming 
students and teachers from a number of 
universities, in particular to enable students 
to gain insights into the opportunities to 
progress careers in aerospace. 
•	 For the last seven years Senior Flexonics GA 
has been working with a local women’s 
correctional facility on their Work Release 
Program. The programme supports inmates 
to transition out of prison by, in conjunction 
with a local Community College, providing 
training and employment at this critical time. 
The participants benefit from an on-site CNC 
machine training “bootcamp”. In addition, GA 
works with a local college to provide job 
shadowing to students with autism – 
“Uniquely Abled Academy program”.
•	 As in previous years, Senior Flexonics India 
identified a number of community projects 
and charities they are going to support during 
the year. In 2024, they installed a Reverse 
Osmosis (RO) plant to provide access to safe 
drinking water for pupils at a government 
school for girls. The RO plant installed has a 
capacity of 500 litres per hour.
•	 Senior Aerospace Weston continued their 
successful partnership with the Barry Kilbride 
Prostate Cancer Appeal by taking part in a 
charity bike ride. A team of cyclists from 
Weston completed over 200 miles in three 
days and raised money for the charity 
through sponsorship.
•	 Senior Flexonics Pathway collaborated 
with other local businesses to provide 
Thanksgiving turkeys to the South Texas 
Vocational Technical Institute.
•	 Our Senior Flexonics Cape Town has 
continued to support Lawrence House, 
a home for orphaned boys and girls by 
donating essential items such as clothing, 
food and stationery. In addition, our Cape 
Town employees worked with Grace Animal 
Sanctuary and Faith Village, an organisation 
that supports vulnerable children. 
Outcome of engagement
•	 Senior Aerospace Thailand education 
community partnerships have helped 
promote aerospace and engineering as 
a career by providing real life experiences 
to develop, build and encourage the next 
generation of aerospace innovators.
•	 The Work Release Program supported by 
Senior Flexonics GA enables individuals 
transitioning from prison to acquire new 
skills, acclimatise to real world employer 
expectations, earn and save some money 
in order to become self-sufficient once 
released from the correctional facility 
and develop a work history. The work 
shadowing opportunities provided by 
GA for students with autism helps prepare 
them for future employment.
•	 Through their charitable endeavours, Senior 
Flexonics India ensures school students have 
access to potable water, thereby fostering 
better health and wellbeing. 
•	 Senior Flexonics Pathway, through their 
participation in the Thanksgiving event, 
ensured that 593 students were able to enjoy 
a hearty Thanksgiving meal. For some 
students it will have been the only 
Thanksgiving meal they received. 
•	 Senior Aerospace Weston’s ongoing support 
for the Barry Kilbride Prostate Cancer Appeal 
enables them to continue to support men in 
the local community and raise awareness of 
the importance of men’s health issues.
•	 Senior Flexonics Cape Town and the generosity 
of our employees has made a positive impact 
on the lives of vulnerable and less fortunate 
individuals in their local community by providing 
food and essential items.

REPORT

Capital Expenditure Request – Senior Flexonics Crumlin New Facility
At the start of 2024, the Board considered the proposal to relocate Senior Flexonics Crumlin (Crumlin) to a more suitable site 
to support growth and better showcase its design and development capabilities. Crumlin offers expert design, development, 
testing and manufacturing capabilities and is the Primary European Design and Development centre for thermal management, 
fluid conveyance and flexible connectors, which merited its justification. As a result of recent successes in thermal management 
products for EV markets, Crumlin had begun manufacturing battery thermal management plates and needed additional space 
to allow further expansion.
S.172 Considerations
(a)	the likely consequences of any 
decision in the long-term
As part of its decision-making, the Board assessed such factors as the impact on the Group’s budget 
and financial planning, the returns on investment, environmental impact, opportunities to leverage the 
existing skills of the employees and the alignment with the Group’s long-term strategy.
The Board reviewed the proposal regarding the relocation of Crumlin to a new facility and deemed the 
request represented significant future opportunities to accelerate the profitability of the operating 
business and was equally in line with Senior’s strategic focus of highly engineered, IP-rich, fluid 
conveyance and thermal management expertise and capabilities and its Purpose of helping engineer 
the transition to a sustainable world for the benefit of all stakeholders. 
(b)	interests of Company’s employees
The Board recognised the value of leveraging opportunities of the existing skills and future-proofing 
the operating business.
(c)	fostering relationships with the 
Company’s suppliers, customers 
and others
The Board considered the strategic requirements of Crumlin’s and the rest of the Flexonics Division’s 
customers and the opportunities these presented for the Group.
(f)	 need to act fairly between members
The Board was cognisant that the relocation of Crumlin was important in creating long-term value 
for shareholders.
Outcome: The Board approved Crumlin’s relocation proposal and promoted cooperation between Crumlin and the rest of the Flexonics Division’s 
operating businesses.
Double Materiality Assessment
During the year, the Company performed its first double materiality assessment, which evaluated Senior’s sustainability matters 
from both financial and impact perspectives.
S.172 Considerations
(a)	the likely consequences of any 
decision in the long-term
The Board recognised the importance of identifying sustainability-related risks, impacts and 
opportunities that can enhance decision-making, contributing to a more sustainable business model. 
(b)	interests of Company’s employees 
A range of internal and external stakeholders were consulted as part of the DMA process, to ensure 
the Company captured comprehensive points of view for a mix of geographies, business and market 
expertise, as well as commercial relationships with Senior.
(c)	fostering relationships with the 
Company’s suppliers, customers and 
others
(d) the impact of the Company’s operation 
on the community and environment 
(f)	 need to act fairly between members
By incorporating sustainability considerations into the Company’s decision-making, we are future 
proofing the business, making it more resilient in delivering long-term value.
Outcome: The Board reviewed and approved the list of material sustainability-related topics. The Company will use these insights to enhance its 
sustainability strategy.
Examples of S.172 considerations in practice
This section provides some examples of the decisions taken or implemented by the Board in 2024. The Directors acknowledge that every decision 
they make will not always result in a positive outcome for all of Senior’s stakeholders. However, by considering the Company’s Purpose, Vision and 
Values, together with our strategic priorities and having a process in place for decision-making, we aim to ensure that our decisions are considered, 
proportionate and balanced.

KEY PERFORMANCE INDICATORS
The Group highlights five financial and two non-financial metrics 
to measure progress in implementing its strategy.
Non-financial metrics
The Group’s non-financial objectives are 
as follows:
•	 to reduce the Lost Time Injury Illness 
Rate (per 100 employees) to 0.3 
by 2025; and
•	 to reduce the absolute Scope 1 and 2 
Greenhouse Gas (“GHG”) emissions 
by 30% by 2025 (compared to 2018 
base year).
The key performance indicators (“KPIs”) 
are determined as follows:
•	 CO2 emissions is an estimate of the 
Group’s carbon dioxide emissions 
in tonnes equivalent; and
•	 lost time injury illness frequency rate 
is the number of OSHA (or equivalent) 
recordable injury and illness cases 
involving days away from work per 
100 employees.
The Group’s approach to calculating and 
reporting our GHG emissions follows the 
GHG Protocol.
2024’s reporting has incorporated Scope 2 
greenhouse gas emissions (associated 
with electricity consumption) calculated 
using both the Location and Market 
Based methods. 
The Scope 1 and 2 emissions Location 
Based and Market Based (FY24) are 
independently verified in accordance 
with the International Standard on 
Assurance Engagements ISAE 3410 
(limited assurance).
In calculating GHG emissions, the Group 
has used the financial control approach 
under which a company accounts for 100% 
of the GHG emissions from operations over 
which it has control. This covers all wholly 
owned operations and subsidiaries of the 
Group for financial reporting purposes.
Senior is on track to meet our 2025 targets 
for Scope 1 and 2 GHG emissions and lost 
time injury illness rate. Further details 
of the Group’s performance, including its 
long-term performance trends, are shown 
on pages 14 to 19. More detail on the 
Methodology can be found on page 16.
  Increased	
  Decreased

In 2024, our absolute Scope 1 and 2 Greenhouse Gas (“GHG”) emissions reduced 
from 57,418 tCO2e (2018) to 38,238 tCO2e. We have met our SBTi 2025 target with 
a 33.4% reduction against our 2018 base year.
We experienced a decrease in the Lost Time Injury and Illness Rate from 0.32 in 2023 
to 0.19 in 2024. The Total Recordable Injury and Illness Rate remained stabe at 0.63.

Financial metrics
The Group’s financial objectives for 2024 
were as follows:
•	 to achieve revenue growth (at constant 
exchange rates) in excess of the rate 
of inflation;
•	 to increase the Group’s return on revenue 
margin each year;
•	 to increase adjusted earnings per share 
on an annual basis;
•	 to generate sufficient cash to enable the 
Group to fund future growth and to follow 
a progressive dividend policy; and
•	 to maintain an overall return on capital 
employed in excess of the Group’s cost 
of capital and to target a pre-tax return in 
excess of 13.5% on a post IFRS 16 basis.
The KPIs are determined as follows:
•	 revenue growth is the rate of growth 
of Group revenue, at constant 
exchange rates;
•	 return on revenue margin is the 
Group’s adjusted operating profit
divided by revenue;
•	 adjusted operating profit is defined 
in Note 9;
•	 adjusted earnings per share is defined 
in Note 12;
•	 net cash from operating activities is 
available from the Consolidated Cash 
Flow Statement; and
•	 return on capital employed is the Group’s 
adjusted operating profit divided by the 
average of the capital employed at the 
start and end of the period, capital 
employed being total equity plus net 
debt (defined in Note 31c).
The Group’s financial objectives for 2025 
will be aligned to the new medium-term 
financial targets as noted on page 33.

As discussed in the Group Chief Executive 
Officer’s Statement, the year-on-year 
increase was a result of growth in the 
Aerospace Division and an anticipated 
reduction in the Flexonics Division. The 
impact on the Divisions is set out in the 
Divisional Reviews, on pages 60 to 62.
The Group generated net cash from operating 
activities of £49.4m, which funded gross 
capital expenditure of £43.2m in 2024. 
The year-on-year increase was driven by 
more effective management of working 
capital and increased operating profit.

increased by 10 basis points. This reflected 
the benefits from higher prices, operational 
efficiencies and higher Aerospace 
volumes, offsetting the impact of lower 
volumes in Flexonics. 
Return on capital employed (“ROCE”) 
decreased to 6.8%. The decrease in ROCE 
was mainly a result of higher inventory and 
investment in growth not yet fully offset by 
the growth in profit, which was impacted by 
near-term temporary customer led headwinds.

The decrease also reflects the impact of 
higher underlying interest and tax costs.

RISKS AND UNCERTAINTIES
Our approach to risk management
Identifying and effectively managing risks is 
essential to the achievement of the Group’s 
strategic priorities and supporting the Group’s 
Purpose and sustainability initiatives. 
The Group’s Business Model is described on 
pages 2 and 3, our strategic priorities are on 
pages 34 and 35, our Purpose is described 
on the inside front cover and Sustainability 
starts on page 12. 
The Board is responsible for the Group’s 
integrated risk and assurance framework, 
ensuring that the Group’s risk process and 
systems of internal control are robust, 
continuously monitored and evolve to address 
changing business conditions and threats. The 
Board also provides direction and sets the tone 
on the importance of risk management. 
Responsibility for the monitoring and review of 
the effectiveness of the Group’s risk and 
assurance framework has been delegated by 
the Board to the Audit Committee. The risk 
process is reviewed and agreed annually with 
the Audit Committee. The Director of Risk and 
Assurance delivers a comprehensive report on 
risk, assurance and various compliance activities 
at each Audit Committee meeting and presents 
to the Board twice a year. 
The Group embeds risk management within its 
existing business processes across all levels 
within the Group. Risk tolerance is reflected 
throughout our control framework by way of the 
Group’s Delegation of Authority, Code of 
Conduct and internal controls system. The 
Group’s principal risk register is derived from a 
catalogue of approximately 50 identified risks 
encompassing strategic, financial, operational, 
environmental and other external risks. This 
catalogue of identified risks serves as the 
foundation for comprehensive risk assessments 
completed by every operating business and by 
the Executive Committee as part of the annual 
strategic planning process. The risk 
assessments also consider emerging risks as 
detected through internal activities and external 
sources. Emerging risks are risks which may 
develop but have a greater uncertainty attached 
to them in terms of likelihood, timing and 
velocity. Emerging risks are monitored and 
formally added to our identified risk catalogue 
when the risk solidifies within the Group’s 
strategic planning horizon. 
The Group also conducts functional risk 
assessments, targeting areas such as fraud, 
tax evasion facilitation and sustainability, 
which encompasses environmental, social and 
governance elements. The risk assessment 
specific to sustainability follows a double 
materiality assessment approach which 
incorporates feedback from internal and external 
stakeholders and considers the financial impacts 
of sustainability topics on the Group as well as 
the impacts from the Group on people and the 
planet. The sustainability double materiality risk 
assessment process considers multiple time 
horizons and applies scenario analysis to the 
most material climate-related transition and 
physical risks. Sustainability-related risks are 
also considered as part of the overall Group risk 
assessment completed during the annual 
strategic planning process and rank within the 
Group’s principal risks. 
During the risk assessment process, all risks 
in the identified risk catalogue are evaluated 
against our Purpose, strategy and Values to 
understand their likelihood and impact of 
occurrence, with those risks deemed as 
significant forming our register of principal risks. 
Once the principal risks have been identified, 
mitigating controls and relevant policies are 
documented and additional mitigating actions 
are developed where appropriate. An owner 
and due date are assigned to each action 
and progress towards completion is closely 
monitored. The operating business risk registers 
are refreshed regularly and reviewed by 
Divisional Management and the Executive 
Committee. The Executive Committee conducts 
its risk assessment twice a year and principal 
risks are discussed at each Executive 
Committee meeting. All principal risks are 
assessed for our financial viability scenarios to 
see if they could have a material financial impact 
individually or if they materialised together.
The Board performs robust, semi-annual 
assessments of the principal and emerging risks 
facing the Group. In addition, the Board regularly 
assesses outputs from the integrated risk and 
assurance framework and takes comfort from 
the “three lines of defence” risk assurance 
model. The first line represents operational 
management who own and manage risk on 
a day-to-day basis through effective internal 
controls. The Group Executive Committee and 
Divisional Management monitor and oversee 
these activities, representing governance and 
compliance as the second line.

and Assurance 
“Our comprehensive risk 
management framework 
helps the Group navigate 
the constantly evolving 
business environment.”

STRATEGIC  
REPORT

The third line is the independent assurance over 
these activities provided by internal and other 
external assurance. The internal assurance 
programme includes a combination of broad 
scope internal audits, evaluating financial, 
information technology and security, human 
resources, governance and other controls, 
plus limited scope thematic reviews designed 
to provide assurance over targeted risk areas. 
Internal audits are conducted either in person 
or virtually, with all Group businesses audited 
on a multi-year rotational schedule based on 
a variety of factors, including site-specific risks, 
prior audit results and changes within local 
management. Thematic reviews are deployed 
across the entirety or a cross section of the 
Group dependent on the risk being targeted. 
In addition, all Group businesses must complete 
a comprehensive annual Controls Self-
Assessment, allowing the Group to identify 
and address gaps in compliance with the 
Group’s governance policies and internal 
control standards. Divisional Management, 
the Executive Committee and the Audit 
Committee monitor the completion progress 
of improvement actions resulting from internal 
audits, thematic reviews and the Controls 
Self-Assessment. 
The key elements of the Senior risk 
management process are shown on the 
following page.
During 2024, the Group carried out 
assessments of the principal risks and 
uncertainties that could threaten the Group’s 
Business Model or achievement of its strategic 
priorities. The risk assessments included 
consideration of emerging risks (as defined 
on page 50) which for 2024 included potential 
risks to the Group from employment trends 
and the anticipated cost and resource pressures 
resulting from ever-expanding compliance 
and governance reporting requirements. 
As a result of the risk assessments, Inflation 
and Pandemic have been removed from the 
Group’s principal risks. Rates of inflation 
moderated considerably in 2024, driven by 
further stabilisation of energy prices and supply 
chains during the year, but the Group continues 
to closely monitor and actively manage trailing 
inflationary impacts. Additional information 
regarding our ongoing inflation mitigation 
activities can be found within our Programme 
Management risk on page 57 and our Financing 
and Liquidity risk on page 59. 
With regards to Pandemic, 2024 saw further 
easing of COVID-19 restrictions as the US, UK 
and other countries continued to significantly 
reduce or completely eliminate testing and 
isolation guidelines. The Group remains vigilant 
to the potential impacts of a resurgence of the 
COVID-19 pandemic or a manifestation of a 
completely new regional or global pandemic.

A  B  C  D  E
Principal Risk
Changes in critical trade relations factors, such as tariffs, sanctions and exchange 
rates, resulting from geopolitical events have raised concerns over the future 
impacts on international trade, including export revenues, material availability and 
cost and the ability to employ foreign nationals. Increases in consumer product 
costs resulting from trade relations factors could impact demand for those 
products. Shifts in political regimes and government spending programmes can 
lead to higher taxation and have an impact on earnings. 
There is a risk that there will be a global economic downturn impacting some 
or all of the sectors within which the Group operates.
How we manage it
Divisional Management and the Executive Committee closely monitor 
economic and geopolitical trends that may impact the operating businesses 
through regular business reviews. Contingency planning is undertaken to 
minimise operational disruption where necessary. 
The Group employs tax, treasury and trade compliance specialists who 
maintain the Group’s trade-related compliance programmes and continually 
monitor the impacts of evolving trade relations from regulatory, supply chain, 
people and financial perspectives. 
The Group responds to potential margin impacts resulting from trade relations 
factors through leveraging contractual protection measures and actively 
engaging in impact mitigation dialogue with suppliers and customers.
The Board ensures that it is kept informed of significant trade developments in 
order to assess the impact on the Group and take action as appropriate.
The Group’s Treasury Committee closely monitors potential changes to 
international tax and treasury regulations and tariff programmes to understand 
the likely impacts on the Group.
Focus in 2024
While supply chain constraints and inflationary pressures continued to ease 
in 2024, shifts in the political climate in various countries have increased 
uncertainties around tariffs, taxes and other trade relations factors. We are 
carefully monitoring all tariff, tax and trade relations actions that present the 
greatest possibility of adverse impacts on the Group, particularly the escalation 
of tariff activities between the US, Canada, Mexico, EU and China. The 
development of adaptable mitigation plans is underway and response actions 
include enhancement of our team of trade compliance specialists, recovery 
of additional tariff costs from customers, where appropriate, and evaluating 
opportunities to transition supply sources to more favourable locations.

Principal Risk
An inability to implement the Group’s strategy and/or effectively manage the 
Group’s portfolio could have a significant impact on the Group’s ability to 
generate long-term value for shareholders.
Ambiguity surrounding the Group’s strategy and strategic priorities may result 
in investors failing to recognise the value of the Group’s investment case.
How we manage it
The Group regularly reviews its strategy and portfolio to maximise long-term 
shareholder value. Where appropriate, divestments will be considered.
The Group has a well-documented M&A framework that includes proven 
research analysis, a committee that evaluates opportunities against a wide 
variety of strategic, financial, operational and cultural criteria, transaction 
engagement, management and due diligence processes and post-acquisition 
integration procedures designed to be efficiently executed by an experienced 
cross-functional team.
A comprehensive process for efficiently completing strategic divestments has 
been successfully deployed with past divestments.
Post-acquisition/divestment reviews are conducted, as appropriate, 
to demonstrate accountability to the Board and analyse lessons learned. 
Additional information about projects that support expansion of our current 
businesses and products can be found starting on page 36.
The Group has an adaptable response framework to ensure sufficient focus 
remains on the Group’s core strategic priorities during critical operational, 
strategic and financial challenges.
Focus in 2024
The Executive Committee and Board carried out annual assessments of our 
strategic objectives, end markets, capabilities and technologies and determined 
that the Group is well positioned to deliver its strategy and continue the transition 
through the evolving Net Zero world. The Group continues to focus on:
•	 refining our portfolio with a focus on creating a higher margin business with 
more engineered design content across our product range;
•	 investment in new technology and product development in our core markets 
with an emphasis on fluid conveyance, thermal management and expansion 
of our additive manufacturing capabilities;
•	 supporting our customers’ transition towards a lower-carbon future by 
developing innovative new product offerings while continuing to deliver 
better designed, lighter and more efficient conventional products;
•	 expanding our presence in markets with attractive structural growth potential 
through leveraging our expertise in our traditional core markets; and
•	 liquidity and effective cash management to support growth.
The sale process of Aerostructures is now at an advanced stage.

B  F  G  
Principal Risk
There is a risk that climate change and/or the measures taken to address it may 
have an adverse impact on the Group. Climate change may result in extreme 
weather events that may impact our ability, or that of a supplier, to meet our 
customers’ requirements. 
Our customers’ products may evolve to require new technology, such as 
electrification. This also presents an opportunity for the Group to be involved 
in replacement technologies.
Increasing legislation aimed at accelerating decarbonisation may increase our 
operating costs. It may also change consumer behaviours impacting on our end 
markets. For example, consumers may fly less often.
How we manage it
To mitigate the impact of catastrophic events, such as an extreme weather 
event, each site has a scenario-based Business Continuity Plan which is tested 
on an annual basis. The Group also has insurance which helps to protect profits 
in such situations.
The Group continues to invest in and develop solutions relevant to changing end 
markets. Examples include battery cooling, waste heat recovery, heat sink in 
hybrid car technologies and additive manufacturing solutions for aerospace.
Climate change risks and opportunities are assessed annually by a multi-
disciplinary team as part of the Group’s sustainability-related double materiality 
risk assessment. Additional information regarding this assessment can be 
found starting on page 12. 
The Group’s SBTi-approved emissions reductions targets covering GHG 
emissions from the Group’s operating businesses are consistent with reductions 
required to limit climate warming to 1.5°C and are aligned with Net Zero as 
Near-Term and Overall Targets. SBTi has approved the following targets:
•	 Overall Net Zero Target – The Group commits to reach Net Zero GHG 
emissions across its value chain by 2040 from a 2018 base year;
•	 Near-Term Targets – We commit to reduce our absolute Scope 1 and 2 GHG 
emissions by 30% by 2025 compared to a 2018 base year and for Scope 3 
GHG emissions, the Group also commits that 82% of its suppliers by spend, 
covering purchased goods and services and capital goods, will have 
science-based targets by 2025; and
•	 	Long-Term Targets – The Group commits to reduce absolute Scope 1, 2 
and 3 GHG emissions 90% by 2040 from a 2018 base year. 
The Group Corporate Framework includes a Sustainable Sourcing Policy 
mandating key suppliers adhere to the Group’s Sustainable Sourcing Standards, 
which include environmental management requirements such as Near-Term 
Scope 1 and Scope 2 GHG emission targets and pollution, waste and wastewater 
management systems. Ninety-one of our key suppliers already have carbon 
reduction targets and we continue to work with remaining suppliers.
Focus in 2024
Information regarding TCFD and Sustainability, including progress against 
near-term science-based targets, our CDP ratings and awards, supplier 
engagement and how the Group is leveraging our technology and product 
development to drive progress towards Net Zero can be found starting on

A  B  C  E  F  
Principal Risk
The Group must innovate in order to continue to win new business and achieve 
profitable growth. There is a risk that the Group does not continue to innovate 
and implement technological change, resulting in its technology and/or 
products becoming uncompetitive, less desirable or obsolete.
New technologies may have an impact on the Group’s markets, for example 
electric vehicles and hydrogen aircraft.
How we manage it
The Group develops products to support the move to low-carbon technologies 
and sustainability in the land vehicle, industrial and aerospace markets. 
The Group has identified specific technology themes and focus areas that 
inform the product life cycle and technology development roadmaps across 
both the Aerospace and Flexonics Divisions. The Group also has a Technology 
Council which meets regularly to discuss innovation and technological changes 
across our various businesses and markets. 
The Group invests in two enabling technologies which underpin our product 
development activity across all market sectors: Additive Manufacturing (“AM”) 
and Digitisation. Our Advanced Additive Manufacturing Centre (“AAMC”) 
continues to maintain and add various industry-leading AM process 
certifications. The AAMC team continues to improve its design capability 
to re-engineer existing product designs via AM to deliver significant weight 
savings and performance enhancements.
Global Marketing Teams for each technology focus area co-ordinate 
development activities across various operating businesses to ensure that 
customer requirements and industry trends are addressed.
The Group invests in machining and fabrication technology enhancements 
to improve process efficiency and reduce cost.
The Senior Operating System delivers best practice tools for innovation 
and product development across the Group.
The Technology section, starting on page 36, details the Group’s technology 
themes and product development case studies. 
Focus in 2024
In 2024, the Group maintained focus on five specific Technology Focus areas – 
Hydrogen, Electrification, Heat Exchanger development, Additive Manufacturing 
and Digitisation. We continue to invest in new product development and 
emerging technologies within these focus areas, including significant progress on:
•	 the use of high-pressure hoses in hydrogen production, clean energy and 
semiconductor markets;
•	 delivering the first of a series of advanced expansion joints to support 
100MW electrolyser hydrogen production;
•	 demonstrating internally and validating with customers the applicability 
of a broad range of products to support Sustainable Aviation Fuel (SAF); 
•	 developing vacuum jacketed hosing for cryogenic fluid conveyance of liquids 
and gases through successful collaboration between the engineering 
communities of several Senior operating businesses; 
•	 collaboration with several Urban Air Mobility and eVTOL companies to enhance 
thermal management and low-pressure fluid conveyance in their products; 
•	 proving the viability of AM for critical heat exchanger components in 
conjunction with a major aero-engine manufacturer; and
•	 analysing the potential benefits of using artificial intelligence (AI) within our 
operating businesses to explore how we can improve the operational 
efficiency of the complex quality assurance processes necessary for high 
accuracy engineering techniques.
In 2024, we continued our successful Innovation Competition, inviting our 
operating businesses to submit innovation projects focused on process 
technology, new products or environmental cost savings for judging and 
recognition. The 2024 winner was focused on the use of laser welding for 
thermal cooling plates in electrification applications. The number and quality 
of entries in the competition increases with each year. 
The Group remains focused on sustainability as a driver for new product 
development and market expansion through leveraging existing capabilities, 
expertise and products in thermal management and fluid conveyance into new 
adjacent markets such as space, marine, advanced nuclear and hydrogen.

Operational
Customer disruption 
 
1  2  5  
A  B  C  E
Principal Risk
Supply chain constraints, labour shortages and other operational disruptions 
may leave customers unable to meet current sales commitments and/or 
respond to increases in market demands. As a result, there is a risk that 
customers do not honour firm order schedules, delay programme ramp-up 
and/or postpone new programmes.
How we manage it
The Group has fostered long-lasting and cooperative relationships across its 
customer base.
In furtherance to its strategic priorities, the Group actively seeks to grow the 
business through diversification of its customer base and new product innovation. 
The Group closely monitors market trends and developments through in-house 
market research analysis. 
There is a Group Contract Review Policy which is mandatory for all operating 
businesses and requires comprehensive financial modelling and sensitivity 
analysis of contractual terms and assumptions.
Focus in 2024
2024 presented additional headwinds from some of the Group’s key aerospace 
customers who continue to wrestle with operational challenges. The Group is 
carefully monitoring the impacts resulting from demand and build rate variability, 
heightened scrutiny of quality and safety conformance, imbalance of supply 
between different parts of customer programmes, labour disruption and the 
potential for disturbances resulting from merger and acquisition activity. 
In 2024, the Group continued to focus on:
•	 collaborating with our customers to understand their demand variability 
and potential schedule changes in order to agree acceptable build schedules 
and other solutions to mitigate the impacts of sales demand fluctuations on 
the Group; 
•	 diligently managing supply chain challenges to meet our product delivery 
objectives in support of customer operations;
•	 adapting staffing levels in response to programme fluctuations while 
maintaining a focus on planning for anticipated long-term labour and skills 
requirements; and
•	 continuing to identify overhead reductions through cost containment 
initiatives and efficiency improvements where possible.
Operational
Cyber/information security
 
1  3  
B  
Principal Risk
The risk that the Group is subjected to external threats from malware, hackers 
or other malicious actors, potentially causing critical or sensitive data to be lost, 
corrupted, made inaccessible, or accessed by unauthorised users, resulting in 
the potential for business disruption and financial and/or reputational loss. 
The cyber threat landscape is continually evolving, with threat actors 
developing, implementing and incorporating new methods and tools, including 
artificial intelligence (“AI”), to identify and exploit gaps in Information Security 
(“IS”) defences. In addition, alternate work arrangements, such as remote 
working or hybrid schedules, are now common in today’s office environment 
and can increase IS risks. 
How we manage it
The Group has a rolling three-year strategic roadmap focused on continual 
improvement in people, process and technology. The roadmap accounts for 
the dynamic nature of the cyber threat landscape and builds on our layered 
security defence model consisting of preventative, detective and responsive 
technical controls.
IS risk is closely monitored by the Board via regular updates from the Group 
IS team and the Director of Risk and Assurance. 
The Group has dedicated IS capability in place with a wide range of proactive 
and reactive security controls, including up-to-date antivirus capability across 
our operating businesses and network and system monitoring to identify 
vulnerabilities and potential threats.
A multi-year rotational IS assurance review programme is in place to assess 
and enhance compliance with established IS controls, policies and procedures. 
IS controls are also confirmed via the annual Controls Self-Assessment. 
Vulnerability metrics have been developed and are actively reviewed by 
Divisional Management and the Executive Committee.
The Group has a risk management framework specific to Information 
Technology (“IT”)/IS. 
With our decentralised Business Model, each operating business deploys a 
suite of protection and monitoring services, including endpoint detection and 
response, vulnerability management and cyber threat intelligence. These are 
fully monitored by our centralised Group IS team to ensure consistency, 
continuity and rapid remediation.
Technology-led security controls are further supported by a clear and 
documented series of policies, standards and playbooks.
Employees receive annual awareness training on cyber-related issues 
and the Group maintains a cyber-awareness campaign to alert employees 
to cyber threats.
A near miss and incident reporting process is deployed across the Group 
to alert IT/IS teams of immediate cyber threats.
Focus in 2024
The Group remains committed to full compliance to our IT/IS policies and 
diligent monitoring of the IS environment. 2024 actions included:
•	 implemented quarterly IT/IS collaboration meetings between Group IS 
and operating business leadership and IT/IS teams; 
•	 continued to seek independent accreditation against external security 
frameworks, including achieving accreditation under the National Cyber 
Security Centre’s (NCSC) Cyber Essentials scheme for five of the Group’s 
UK-based operating businesses and Trusted Information Security 
Assessment eXchange (TISAX) accreditation for the Group’s Cape Town 
location; 
•	 conducted targeted cyber security awareness and culture training for site,

Operational
Supply chain challenges
 
1  2  3  4  
A  B  C  D  E
Principal Risk
Suppliers may be unable or unwilling to respond to increases or decreases in 
demand due to operational and other issues such as quality concerns, labour 
disruption or trade relations factors. This may impact our ability to supply our 
customers, operate efficiently and/or optimise inventory held.
Critical materials or components may become temporarily or permanently 
unavailable, leading to an inability to meet production commitments.
Supply chain disruption can lead to higher volatility in delivery schedules as 
customers adjust demand to protect their production capabilities. This may 
challenge the Group’s ability to meet customer schedule, quality and cost 
requirements, resulting in potential delays, penalties and cost overruns.
In extreme cases some suppliers may face financial difficulties and go out 
of business.
How we manage it
The Group closely monitors the resources required to deliver customer demand 
and the resilience of our supply chain. Where supply chain challenges occur, we 
work closely with customers and suppliers to resolve those issues, including 
reducing over-reliance on individual suppliers, where possible.
The Group has deployed the Senior Operating System to provide operating 
businesses with a toolkit to optimise the use of lean and continuous 
improvement techniques, supplier management and other operational best 
practice processes. 
Operating businesses are required to maintain strong internal controls over 
supplier management from new supplier selection to performance monitoring 
and management of existing suppliers.
Our core Values (see page 2) emphasise operating with integrity and respect, 
which allows the Group to cultivate strong, long-term relationships with 
critical suppliers. 
Focus in 2024
Our supply chain continued to stabilise during 2024, but supply interruptions 
persist in certain markets and industries. As a result, the Group continues to 
face protracted delivery lead times and operational disruption in affected 
programmes stemming from material and shipping media shortages, quality 
issues in incoming materials and components and labour disruption in key 
suppliers. We also continue to closely monitor the potential for supply 
disruption resulting from the ongoing conflicts in Ukraine and the Middle East. 
The Group has maintained the initiatives previously deployed to mitigate the 
impacts of supply chain challenges, including:
•	 spotlighting ongoing supply chain challenges in operating business reviews 
and Executive Committee meetings to ensure the challenges are being 
effectively addressed; 
•	 maintaining close and frequent communication with customers regarding 
delivery schedules, issues with directed supply sources, the need to qualify 
additional supply sources, options for alternate materials or components and 
potential incremental costs to mitigate supply chain disruptions; 
•	 working with suppliers to manage lead times and maximise the benefits 
from long-term supply agreements, where applicable; 
•	 holding appropriate levels of safety stock, where necessary, to ensure a 
consistent flow of materials and/or components for production; 
•	 leveraging supplier relationships across the Group to identify alternate supply 
sources and opportunities to streamline or consolidate supply requirements; 
and
•	 applying the Senior Operating System and our engineering expertise to 
generate innovative solutions to supply chain challenges.
Operational
Programme management 
 
1  2  3  5  6  
A  B  C  D  E
Principal Risk
The ability to introduce new products in line with customer requirements and to 
respond appropriately to increases or decreases in demand thereafter is key to 
achieving the Group’s strategic objectives.
There is a risk that the Group is unable to respond quickly enough to changes 
in demand, potentially resulting in excess inventory and/or an inability to meet 
schedule and cost requirements resulting in delays, penalties, cost overruns or 
asset write-downs.
Supply chain disruptions, higher material costs, rising energy prices and labour 
shortages could result in a reduction of earnings from existing programmes if 
the Group is unable to secure mitigating price adjustments from customers. 
Higher production costs resulting from inflationary pressures can also reduce 
our ability to remain cost competitive.
Changes across a variety of production requirements, such as fluctuations 
in material supplies, volatility in customer ordering and employee retention 
and training, may challenge the Group’s ability to maintain programme 
quality specifications, leading to the potential for higher costs to maintain 
and/or demonstrate compliance with quality requirements or greater risk 
of product defects.
How we manage it
The Group is experienced in bidding and launching new products. Formal New 
Product Introduction (“NPI”) processes, such as Advanced Product Quality 
Planning (“APQP”) are in use across our operating businesses.
There is a Group Contract Review Policy which is mandatory for all operating 
businesses and requires comprehensive financial modelling and sensitivity 
analysis of contractual terms and assumptions. 
The Senior Operating System maintains a strong focus on lean manufacturing, 
continuous improvement, labour efficiency and cost reduction initiatives. 
NPI programmes are subject to regular review by Divisional and Group 
management to ensure that schedule, cost or quality issues are identified 
and dealt with promptly.
The Group monitors market and customer data so that we can be prepared 
to respond to changing market dynamics.
A variety of tools are deployed throughout the Group to prevent, detect and 
manage quality issues, including supplier audits, comprehensive quality 
management systems, internal quality audits, Gemba walks and documented 
root cause analysis.
Focus in 2024
While inflationary pressures eased considerably in 2024, other programme 
management challenges persisted during 2024 driven by lingering pockets of 
supply chain constraints and labour availability issues, regionalised wage 
inflation and an increase in demand fluctuations caused by customer disruption. 
In response, the Group maintained its focus on:
•	 spotlighting key programme management issues in operating business 
reviews and Executive Committee meetings to ensure issues receive 
adequate resourcing and action; 
•	 continuing to work with our customers to ensure that, wherever possible, 
orders within firm windows can be delivered; 
•	 working with our suppliers and managing inventory to balance inventory 
levels where there are delays in firm orders and/or ensure adequate supply 
to meet production demands;
•	 continuing to engage with customers to secure price increases, delay 
contractual price decreases and/or pass through higher production costs to 
mitigate the impact on Group margins where inflationary pressures persist; 
•	 qualifying additional supply sources or options for alternate materials or 
components at potential incremental costs to mitigate supply chain disruptions;
•	 maintaining flexible labour resource plans to adapt to variations in demand 
and production schedules; 
•	 driving labour and overhead cost reductions through efficiency 
improvements where possible; and
•	 responding to the ongoing, elevated level of new requests for quotation.

Price-down pressures
 
1  3  4  5  
A  B  C  E
Principal Risk
Customer pricing pressure is an ongoing challenge within our industries, driven 
by the expectations of airlines, land vehicle operators and governments seeking 
to purchase more competitively priced products in the future. This may put 
some pressure on the Group’s future operating margins.
How we manage it
The Group works closely with its customers to find innovative ways to produce 
products at a lower cost, thus helping customers meet pricing challenges.
The Group is able to consider bundles of products that in total help meet 
customer pricing challenges.
Where appropriate, the Group will actively pass work to some of its cost 
competitive facilities, such as Mexico, Thailand, the Czech Republic, 
South Africa, India, China and Malaysia, with a view to helping satisfy 
customer challenges.
There is a Group Contract Review Policy which is mandatory for all operating 
businesses and requires comprehensive financial modelling and sensitivity 
analysis of contractual terms and assumptions.
Focus in 2024
As supply challenges and inflationary pressures stabilise, customers are 
gradually shifting focus from containing supplier cost increases to initiating cost 
reduction discussions with their supply base. In 2024, the Group continued its 
focus on:
•	 our pragmatic and adaptable pricing response framework enabled the Group 
to secure favourable re-pricing across several key contracts during the year;
•	 working in partnership with customers to support their priorities within the 
contractual terms of existing agreements; 
•	 balancing supplier capabilities and customer demand to manage material 
costs, including approval of alternate supply sources where appropriate; and 
•	 driving labour and overhead cost reductions through cost containment 
initiatives and efficiency improvements where possible.
People and culture
Talent and skills 
 
2  6  
A  B  D
Principal Risk
There is a risk that the Group, particularly in the US and UK, is unable to attract 
sufficient skills and talent and/or is unable to retain the skills and talent it has in 
order to meet demand. Margins may be impacted by higher wage rates 
necessary to retain current employees and/or attract new employees. 
A portion of the Group’s workforce may reach retirement age at the same time, 
creating a gap in skills and labour availability. 
The Group may have insufficient talent to respond to all strategic priorities.
How we manage it
Employee retention, recruitment and resource plans are regularly 
discussed within the operating businesses, Divisional Management 
and the Executive Committee.
The Group HR Director hosts focus groups across a number of the operating 
businesses to solicit constructive feedback from employees and foster 
open communication. 
Operating businesses partner with technical colleges, universities and 
apprenticeship schemes to create talent pipeline programmes.
A Group-wide succession planning exercise is conducted annually to identify 
successors and interim cover for key roles and ensure appropriate development 
plans are in place to support employees in meeting their career goals.
The Nominations Committee reviews management development 
and succession plans twice a year, with a particular focus on critical roles 
and key talent. 
The Group operates an internal leadership development programme 
for nominated high-potential employees. 
The Perform performance and development system is utilised across the 
Group to facilitate objective setting, development planning and performance 
and behaviour assessment. 
The Group HR Director regularly provides people and culture feedback 
to the Board.
Focus in 2024
Labour availability continued to improve during the year, but challenges remain 
within certain roles and geographic locations. In addition, disruption of demand 
from key customers in 2024 compelled the Group to adjust staffing levels in 
response to demand volatility while maintaining readiness for labour and skills 
requirements when demand from affected customers accelerates. We 
continued to closely monitor and manage staffing levels, recruitment and 
retention challenges and other employment trends across the Group. Actions in 
2024 included:
•	 ongoing reassessment of compensation levels against industry and regional 
benchmarks, with off-cycle wage increases or lump sum payments 
offered where necessary to ensure the Group’s compensation offerings 
are competitive; 
•	 enhanced sign-on and candidate referral incentive opportunities for new 
and existing employees;
•	 introducing an internal mentoring programme;
•	 further expanding employee benefit offerings in certain locations to broaden 
healthcare coverage and other wellbeing programme options; and
•	 conducting the 2024 Global Employee Engagement Survey, driving 
development and implementation of localised action plans to respond to 
employee feedback received through the survey and further enhance our 
reputation as a company people want to work for. In addition, a non-financial 
performance target related to Employee Engagement was added to the 
Senior Management annual bonus targets for 2024. More information on 
employee engagement can be found on page 28.

Financial
Financing and liquidity
 
2  3  5  
C  D  E
Principal Risk
The Group could have insufficient financial resources to fund its growth strategy 
or meet its financial obligations as they fall due or insufficient liquidity to meet 
financing covenants.
Foreign exchange movements could have a material impact on the Group’s 
financial performance, both on the balance sheet (translation risk) and income 
statement (transaction risk).
Inflationary pressures may result in higher interest rates, which could impact 
the Group’s earnings.
How we manage it
The Group’s overall treasury risk management programme focuses on the 
unpredictability of financial markets and seeks to minimise potential adverse 
effects on the Group’s financial performance.
The Group enters forward foreign exchange contracts to hedge the 
transactional exchange risk arising on operations’ trading activities in foreign 
currencies; however, it does not enter into or trade financial instruments, 
including derivative financial instruments, for speculative purposes. 
The Group does not hedge translation risk, but aims to match the foreign 
currency of its net debt in similar proportions to its generation of foreign 
currency EBITDA, where practical and economic, in order to provide a natural 
hedge against the Group’s principal lending covenant.
The Group monitors liquidity risks monthly and ensures sufficient headroom in 
its committed borrowing facilities to meet financial obligations across the Group 
as they fall due.
A global notional cash pooling solution is utilised to manage working capital 
funding in the operations and minimise central borrowings.
A significant portion of the Group’s external debt is at fixed rates of interest, 
which mitigates the effect of higher benchmark interest rates that can result 
from inflationary pressures.
Compliance with financial policies, exposure limits and headroom/liquidity limits 
are reviewed by the Group’s Treasury Committee on a regular basis.
The Group’s Treasury Policy is updated and approved by the Board regularly. 
The Group’s viability assessment process considers a base case and risk case 
scenario, which considers the principal risks and uncertainties. 
Focus in 2024
Financing and liquidity initiatives remain vital to mitigating the ongoing impacts 
of the supply chain challenges, inflation and customer disruption. Actions taken 
in 2024 included:
•	 issuing new, six-year tenor $50m US Private Placement loan notes as a 
partial refinancing of long-term debt maturing in 2025;
•	 launching an inventory optimisation project to strengthen our response to the 
ongoing inventory management challenges caused by increasing customer 
demand, residual supply chain issues and disruption driven by customer 
demand fluctuations;
•	 continued compliance with transactional foreign exchange hedging policy 
to mitigate income statement volatility from currency movements; and
•	 the Group’s Treasury Policy was updated and approved by the Board in 
September 2024.
Compliance
Corporate governance breach
 
1  2  3  
A  B  C
Principal Risk
Corporate governance legislation (such as the UK Bribery Act and the US 
Foreign Corrupt Practices Act), regulations and guidance (such as the UK 
Corporate Governance Code and global health and safety regulations) and 
corporate reporting requirements are increasingly complex and onerous. 
A serious breach of these rules and regulations could have a significant impact 
on the Group’s reputation, lead to a loss of confidence on the part of investors, 
customers or other stakeholders, result in financial penalties or fines and 
ultimately have a material adverse impact on the Group’s enterprise value.
How we manage it
The Group has a well-established set of governance policies and procedures 
covering all key areas (our Corporate Framework), including a Group Code of 
Conduct, anti-bribery procedures, Fraud Policy, a Health & Safety Charter, 
an Agents Policy and various policies and procedures over the review and 
reporting of risk management and internal control activities.
Governance and regulatory compliance updates are provided to the Board 
and the Executive Committee at appropriate intervals, and to key Division 
and operational management. 
All employees are required to complete annual Code of Conduct training. 
All EU sites have received training on the General Data Protection Regulations 
and employees in other locations have received training as appropriate to 
their roles.
Focus in 2024
Employees and the Board received annual refresher training on our Code of 
Conduct during 2024. The completion rates typically hover around 94%, 
allowing for new starters who have not yet completed their training immediately 
on joining. The course included content related to anti-bribery, reporting of 
misconduct, unconscious bias and cyber security.
Additional training was conducted for appropriate employee groups on other 
topics including fraud, information security, accounting and financial integrity 
and prevention of facilitation of tax evasion.
The Group’s fraud prevention framework was enhanced by formalising the 
Group’s fraud prevention commitment and procedures via a Fraud Policy 
incorporated into the Group’s Corporate Framework.
The Group Code of Conduct was refreshed during 2024 and a copy of the 
updated Code of Conduct was issued to every employee. Our Sustainable 
Sourcing Policy was also updated during the year.
The Group’s 2024 internal audit programme and Controls Self-Assessment 
were completed as planned, providing a level of assurance that the Group’s 
Code of Conduct, controls, policies and procedures are being followed.

STRATEGIC  
REPORT

The market backdrop for our Aerospace Division 
remains healthy with order books for large 
commercial aircraft at record levels, driven by 
increasing air passenger demand. There were 
some supply chain issues for Airbus and its 
suppliers through the year, and although there 
are clear signs of improvement, we expect there 
to be ongoing issues to be managed given the 
large, planned increases in production. Boeing 
also had specific issues with the cap on 737 
MAX production imposed following the Alaska 
Airlines incident in early 2024 and 3 months of 
lost production on 737 MAX, 767 and 777 due 
to the strike at its factories in The Puget Sound. 
Boeing have now started to ramp up production 
following the recommencement of operations in 
December 2024.
Senior responded to these events dynamically, 
supporting our customers and controlling our 
costs. Nonetheless, these temporary 
headwinds did affect Aerospace profitability 
in 2024 compared to original expectations. 
During the period, adjusted operating profit 
increased by 14.3% to £30.4m (2023 – £26.6m) 
and the adjusted operating margin increased 
by 20 basis points to 4.6% (2023 – 4.4%). 
This increased profitability reflected the benefits 
of price increases and higher volumes. 
Outlook
Increasing aircraft build rates, operational 
efficiency benefits and improved contract pricing 
are expected to drive good growth in Aerospace 
in 2025, with H2 performance expected to be 
higher than H1.
For the full year, Aerostructures is expected 
to improve from a loss making position in 2024 
to an operating profit range of £9m to £11m 
in 2025, with the large majority of that being 
earned in H2.
•	 Collins Aerospace (RTX). New multi-year 
production contracts for the supply of 
precision formed and machined thrust reverser 
structural components for commercial 
aerospace platforms at Airbus and Boeing 
from our Jet Products business in California.
•	 Rolls-Royce. A new 5-year contract for the 
supply of aerofoils for the Pearl engine family 
and manufacturing will be undertaken at our 
business in Thailand.
Performance
Aerospace Division revenue in 2024 increased by 
9.9% year-on-year on a constant currency basis, 
benefiting from increase in demand across all 
market sectors. The increase year-on-year 
reflected the ongoing ramp up in civil aircraft 
production rates, notwithstanding 737 MAX 
volumes being subdued following the Alaska 
Airlines incident in January 2024 and the Boeing 
employee strike from September to November 
2024. Other adjacent markets (mainly the 
semiconductor equipment market) and defence 
also contributed to growth in the division.
The civil aerospace sector had good growth 
during the period with Senior’s sales increasing 
by 11.6% compared to prior year. This was as a 
result of increased deliveries to Airbus 
programmes, higher prices, activity levels 
increasing in our Thailand business as a key 
supplier recovers from a fire last year as well as, 
continued strong growth in revenue from 
Spencer Aerospace (more than 50%). 22% of 
civil aerospace sales were from widebody 
aircraft in 2024, with the other 78% sales being 
from single aisle, regional and business jets.
Total revenue from the defence sector increased 
by £1.8m (1.4%) primarily due to higher sales on 
the F35 programme.
Revenue derived from other adjacent markets 
such as space, power & energy, medical and 
semiconductor equipment, where the Group 
manufactures products using very similar 
technology to that used for certain aerospace 
products, increased by £11.0m (15.4%) due to 
price increases and semiconductor equipment 
market starting to recover.
“The civil aerospace sector

“22% of civil aerospace sales 
were from widebody aircraft 
in  2024, with the other 78%

year-on-year on a constant 
currency basis, benefiting from 
increase in demand across 
all market sectors. Adjusted 
operating margin in 2024 
increased by 20 basis points 
to 4.6%. This increased 
profitability reflected the 
benefits of price increases 
and higher volumes.”

STRATEGIC  
REPORT

In the Group’s power & energy markets sales 
decreased by £12.6m (-9.5%) in the year. Sales 
to other power & energy markets increased by 
£4.8m (5.4%) reflecting growth in sales to 
power generation, nuclear and renewables 
industry customers. Sales to oil and gas 
customers decreased by £17.4m ( 32.8%). 
The Group saw robust demand in our 
downstream oil and gas business, partially 
offsetting a reduction in sales from one of our 
operating businesses to our upstream oil and 
gas customers due to a lower share of this very 
competitive business.
Adjusted operating profit decreased by £1.1m 
compared to prior period as a result of lower 
sales. Nevertheless, operational efficiencies, 
lower costs and favourable product mix helped 
increase margins by 30 basis points to 11.0% 
(2023 – 10.7%).
Outlook
We expect Flexonics performance in 2025 
to be broadly similar to 2024.
In land vehicles, the ramp up of programmes 
recently won means we expect our 2025 
performance to be broadly similar to 2024, 
despite some softness in North America and 
Germany. In power and energy, activity levels 
are expected to be similar to 2024. 
Performance
Flexonics Division revenue in 2024 decreased by 
5.9% year-on-year on a constant currency basis. 
Strong revenue growth from downstream oil 
and gas and nuclear, was offset by lower 
upstream oil and gas business and the 
anticipated softness in land vehicle markets.
Global land vehicle markets softened as 
expected in 2024, nevertheless, our sales 
outperformed key end markets. Group land 
vehicle sales decreased by 3.7% driven by 
softer market conditions which were partially 
mitigated by the benefit from the launch and 
ramp up of new programmes in North America 
and Europe. Senior’s sales to the North 
American truck market decreased by £1.2m 
(-2.0%) with market production decreasing by 
2.3%. Our North American off-highway sales 
decreased £5.2m (-13.5%). Sales to other truck 
and off-highway regions, including Europe and 
India, were flat as growth from India offset 
reduced customer demand in Europe. The 
European truck and off-highway market 
decreased by 26% in 2024 primarily due to the 
weakness of the German economy. Senior’s 
sales, however, only decreased by 1.6% in the 
period as we benefited from the launch and 
ramp of new programme wins. For example, 
Senior Flexonics Olomouc benefited from higher 
sales from a new project launched last year. 
There was also a one-off benefit from a large 
order placed by a Swedish OEM to our Senior 
Flexonics Kassel business. Group sales to 
passenger vehicle markets decreased by £0.8m 
(-1.7%) in the year.
“Operational efficiencies, lower 
costs and favourable product 
mix helped increase margins by 
30 basis points to 11.0%.”
“In 2024, the Flexonics Dvision 
won a contract with Gail India 
Limited to manufacture and

FINANCIAL REVIEW
Financial detail
Group revenue
Group revenue was £977.1m (2023 – £963.5m). 
Excluding the adverse exchange rate impact of 
£25.5m, Group revenue increased by £39.1m 
(4.2%) with growth in the Aerospace Division 
and an anticipated reduction in the Flexonics 
Division. In 2024, 58% of revenue originated 
from North America, 17% from the UK, 
13% from the Rest of Europe and 12% 
from the Rest of the World.
Operating profit
Adjusted operating profit increased by £0.7m 
(1.5%) to £46.5m (2023 – £45.8m). Excluding 
the adverse exchange rate impact of £1.6m, 
adjusted operating profit increased by £2.3m 
(5.2%) on a constant currency basis. After 
accounting for £1.6m amortisation of intangible 
assets from acquisitions (2023 – £2.2m), £3.5m 
site relocation costs (2023 – £0.1m), £1.1m US 
class action lawsuit (2023 – £nil) and £nil net

STRATEGIC  
REPORT

The Group’s adjusted operating margin of 4.8% 
increased by 10 basis points on a constant 
currency basis, with increases in both 
Aerospace and Flexonics divisions. Adjusted 
operating margin in Aerospace benefited from 
price increases and higher volumes. Operational 
efficiencies, lower costs and favourable product 
mix helped Flexonics more than offset the 
impact of lower volumes.
As set out in Note 9, adjusted operating profit 
and adjusted profit before tax are stated before 
£1.6m amortisation of intangible assets from 
acquisitions (2023 – £2.2m), £3.5m site 
relocation costs (2023 – £0.1m), £1.1m US 
class action lawsuit (2023 – £nil) and £nil net 
restructuring costs (2023 – £5.6m). Adjusted 
profit before tax is also stated before net income 
associated with corporate undertakings of 
£1.0m (2023 – £7.6m cost). 
Site relocation costs
Site relocation costs of £3.5m (2023 – £0.1m) 
include £3.0m related to the transfer of some 
manufacturing from Senior Aerospace SSP’s 
facility in California, US, to its cost competitive 
facility in Mexico. The majority of this cost 
relates to recognition of an impairment of £1.9m 
of property, plant and equipment. The Group 
also incurred £0.5m costs (2023 – £0.1m) 
related to the transfer of our Senior Flexonics 
Crumlin business to a nearby high-tech facility 
to better showcase its design, development, 
test and qualification capabilities in support of 
the Group’s strategic initiatives.
Finance costs and income
Finance costs, net of finance income and before 
fair value changes in acquisition consideration 
increased to £13.5m (2023 – £7.5m) and 
comprise IFRS 16 interest charge on lease 
liabilities of £3.4m (2023 – £2.9m), net finance 
income on retirement benefits of £2.0m 
(2023 – £2.1m) and net interest charge of 
£12.1m (2023 – £10.2m). Also in 2023, interest 
unwind on uncertain tax positions of £3.5m was 
included, as described further below in the tax 
section. The £1.9m increase in net interest 
charge was driven by higher underlying interest 
rates on variable rate debt and higher levels of 
indebtedness in 2024 versus the prior year.
Before fair value changes in acquisition 
consideration, gross finance costs were 
£21.9m (2023 – £17.6m) and gross finance 
income was £8.4m (2023 – £10.1m including 
£3.5m benefit of interest unwind on uncertain 
tax positions). The change in fair value on 
acquisition consideration was net income 
of £2.2m (2023 – £2.9m interest unwind), 
comprising £3.6m income, relating to the 
2025 earnout target no longer expected to be 
payable, as a result of the impact of the well 
publicised 737 MAX subdued volumes, partly 
offset by £1.4m interest unwind.
Corporate undertakings
Net income associated with corporate 
undertakings was £1.0m (2023 – £7.6m costs), 
of which £0.8m acquisition costs (2023 – £1.5m) 
and £2.2m income from fair value changes in 
contingent consideration (2023 – £2.9m costs) 
related to the acquisition of Spencer Aerospace 
in November 2022 and £0.4m costs are 
associated with potential disposal and other 
corporate activities (2023 – £3.2m). See Note 30 
to the Financial Statements for further details on 
the financial impact of the acquisition in 2024.
In 2024, net cash outflow related to corporate 
undertakings was £13.0m (2023 – £25.8m), 
comprising £10.7m contingent consideration 
(2023 – £23.9m net deferred consideration) 
for the acquisition of Spencer Aerospace and 
£2.3m (2023 – £1.9m) of costs related to 
potential disposal and acquisition activities.
Profit before tax
Adjusted profit before tax decreased by 14% 
to £33.0m (2023 – £38.3m) reflecting higher 
net interest costs including the non-repeat of 
£3.5m prior year benefit of interest unwind on 
uncertain tax positions. Reported profit before 
tax increased by 22% to £27.8m (2023 – 
£22.8m) mainly due to operating profit and 
corporate undertakings favourable movements 
partly offset by non-repeat prior year interest 
unwind benefit. The reconciling items between 
adjusted profit and reported profit before tax are 
shown in Note 9 to the Financial Statements.
Tax charge/credit
The adjusted tax rate for the year was 10.0% 
charge (2023 – 11.0% credit), being a tax charge 
of £3.3m (2023 – £4.2m credit) on adjusted 
profit before tax of £33.0m (2023 – £38.3m). 
The adjusted tax rate benefitted from the 
recognition of a £2.2m deferred tax asset in 
respect of historical tax losses, enhanced R&D 
deductions in the US and the geographical mix 
of taxable profits. In 2023, the adjusted tax rate 
also benefitted from a release of £7.0m of 
provision for uncertain tax positions. This release 
and associated interest release of £3.5m 
followed a series of steps to simplify the legal 
ownership of the Group’s Americas legal entity 
holding structure.
The reported tax rate was 6.8% charge, being 
a tax charge of £1.9m on reported profit before 
tax of £27.8m. This included £1.4m net tax 
credit against items excluded from adjusted 
profit before tax, of which £0.4m credit related 
to amortisation of intangible assets from 
acquisitions, £1.0m credit related to site 
relocation costs, £0.3m credit related to US 
class action lawsuit and £0.3m charge related 
to corporate undertakings in the year. 
The 2023 reported tax rate was 36.4% credit, 
being a tax credit of £8.3m on reported profit 
before tax of £22.8m. This included £7.0m 
credit related to the release of provision for 
uncertain tax positions as described above and 
£4.1m net tax credit against items excluded 
from adjusted profit before tax, of which £0.6m 
credit related to amortisation of intangible assets 
from acquisitions, £1.5m credit related to net 
restructuring costs, £0.1m credit related to site 
relocation costs and £1.9m credit related to 
corporate undertakings in the year. 
Cash tax paid was £7.4m (2023 – £5.6m) and is 
stated net of refunds received of £1.2m (2023 – 
£2.8m) in respect of UK R&Dexpenditure credit 
payments and tax paid in prior periods.
Tax policy
The Group acts with integrity in all tax matters, 
in accordance with the Group’s ethics and 
business conduct programme. It is the Group’s 
obligation to pay the amount of tax legally 
due and to observe all applicable rules and 
regulations in the jurisdictions in which it 
operates. While meeting this obligation, the 
Group also has a responsibility to manage 
and control the costs of our business, including 
the taxes we pay for the benefit of all our 
stakeholders. The Group seeks to achieve this 
by conducting business affairs in a way that is 
efficient from a tax perspective, including 
maintaining appropriate levels of debt in the 
countries we operate in and claiming available 
tax reliefs and incentives. The Group is 
committed to building and maintaining 
constructive working relationships with the 
tax authorities of the countries in which it 
operates. Further details on our approach 
to tax may be found on Senior’s website at 
www.seniorplc.com. 
Earnings per share
The weighted average number of shares, for the 
purposes of calculating undiluted earnings per 
share, increased to 414.3 million (2023 – 413.3 
million). The increase arose principally due to 
shares released from the employee benefit trust 
to satisfy the vesting of certain share-based 
payments during 2024, partly offset by the 
purchase of shares held by the trust. The 
adjusted earnings per share was 7.17 pence 
(2023 – 10.28 pence, which included a benefit 
of 2.54 pence from the release of the provision 
for uncertain tax positions as described above). 
Basic earnings per share was 6.25 pence 
(2023 – 7.52 pence). See Note 12 for details 
of the basis of these calculations.
Return on capital employed (“ROCE”)
ROCE, a key performance indicator for the Group 
as defined on page 49, decreased by 30 basis 
points to 6.8% (2023 – 7.1%). The decrease in 
ROCE was mainly a result of higher inventory 
and investment in growth not yet fully offset by 
the growth in profit, which was impacted by 
near-term temporary customer led headwinds.

Research and design
The Group’s expenditure on research and design 
was £20.0m during 2024 (2023 – £20.0m). 
Expenditure was incurred mainly on funded 
and unfunded work, which primarily relates 
to designing and engineering products in 
accordance with individual customer 
specifications and investigating specific 
manufacturing processes for their production. 
The Group also incurs costs on general 
manufacturing improvement processes which 
are similarly expensed. Unfunded costs in the 
year have been expensed, consistent with 
the prior year, as they did not meet the strict 
criteria required for capitalisation. 
Exchange rates 
A proportion of the Group’s operating profit in 
2024 was generated outside the UK and 
consequently, foreign exchange rates, principally 
the US Dollar against Sterling, can affect the 
Group’s results. 
The 2024 average exchange rate for the 
US Dollar applied in the translation of income 
statement and cash flow items was $1.28 
(2023 – $1.24). The exchange rate for the 
US Dollar applied to the translation of Balance 
Sheet items at 31 December 2024 was $1.25 
(31 December 2023 – $1.27). 
Using 2024 average exchange rates would have 
decreased 2023 revenue by £25.5m and 
decreased 2023 adjusted operating profit by 
£1.6m. A 10 cents movement in the £:$ 
exchange rate is estimated to affect forecast 
full-year revenue on average by £50m, adjusted 
operating profit by £4m and net debt by £15m.
Cash flow
The Group generated operating cash flow of 
£39.3m (2023 – £34.0m), a cash conversion of 
85% of adjusted operating profit. Free cash flow 
was £17.3m in 2024 (2023 – £15.5m) as set out

provision currency movements (2023 – £(1.3m)) and £nil 
profit on sale of fixed assets (2023 – £(0.2m)).
Capital expenditure
Gross capital expenditure of £43.2m (2023 – 
£35.9m) was 1.1 times depreciation excluding 
the impact of IFRS 16 (2023 – 0.9 times). The 
disposal of property, plant and equipment raised 
£0.1m (2023 – £0.7m). 2025 capital investment 
is expected to be above depreciation (excluding 
the impact of IFRS 16), the majority of which is 
investment on growth projects where contracts 
have been secured, with the rest on important 
replacement equipment for current production 
and sustainability related items.
Working capital
Working capital increased by £18.1m in 2024 
to £179.0m as at 31 December 2024 (31 
December 2023 – £160.9m), of which £1.9m 
increase related to foreign currency movements. 
Inventory was higher particularly in Aerospace 
with planned investment to enable us to meet 
the strong increase in demand from our 
customers and was also as a result of 737 MAX 
production being lower than initially resourced 
for, exacerbated by the Boeing employee strike 
in the Puget sound area, coupled with schedule 
changes in Q4 from a customer who is an 
Airbus tier one supplier. Receivables were 
higher as a result of revenue growth. In 2024, 
working capital increased as a percentage of 
sales by 160 basis points to 18.3% (2023 – 
16.7%). We are likely to see an increase in 
working capital over the coming year to support 
the growth anticipated in Aerospace, however 
working capital as a percentage of sales is 
expected to reduce towards the 17% level.
The Group participates in some non-recourse 
reverse factoring schemes which are arranged 
by our customers as a way of reducing credit 
risk. The trade receivables reverse factored 
under such non-recourse schemes at 31 
December 2024 were £29.1m (31 December 
2023 – £29.1m). The net impact of reverse 
factoring on 2024 was cash neutral in working 
capital (2023 – £5.5m inflow) and the discount 
interest presented within other finance costs is 
a charge of £0.9m in 2024 (2023 – £0.8m). 
These arrangements follow standard market 
terms and conditions and, as noted above, 
are 100% non-recourse to the Group, thereby 
transfer all credit risk to the financial institutions 
who provide the factoring schemes. 
FINANCIAL REVIEW CONTINUED
STRATEGIC  
REPORT
SENIOR PLC ANNUAL REPORT AND ACCOUNTS 2024
66

Dividend 
The Board is proposing a final dividend of 1.65 
pence per share (2023 – 1.70 pence). If 
approved, it would be paid on 30 May 2025 
to shareholders on the register at the close of 
business on 2 May 2025 and payment would 
total £6.8m. This would deliver total dividends 
paid and proposed in respect of 2024 of 2.40 
pence per share (2023 – 2.30 pence), an 
increase of 4.3%. At the level recommended, 
the full year dividend would be covered 3.0 
times by adjusted earnings per share. The cash 
outflow incurred during 2024 in respect of 
dividends was £10.1m (2023 – £6.6m) relating 
to the final dividend for 2023 and the interim 
dividend for 2024. 
We will continue to follow a progressive 
dividend policy reflecting earnings per share, 
free cash flow generation, market conditions 
and dividend cover over the medium-term. 
Goodwill 
The increase in goodwill from £193.3m at 
31 December 2023 to £195.4m at 31 December 
2024 reflects foreign exchange differences 
of £2.1m.
Retirement benefit schemes 
The retirement benefit surplus in respect of 
the Group’s UK defined benefit pension plan 
(“the UK Plan”) decreased by £5.0m to £43.5m 
(31 December 2023 – £48.5m) due to £6.0m 
net actuarial losses and £1.2m running costs 
partly offset by £2.2m net interest income. 
Retirement benefit deficits in respect of the 
US and other territories decreased by £1.2m 
to £6.8m (31 December 2023 – £8.0m). 
The latest triennial actuarial valuation of the 
UK Plan as at 5 April 2022 showed a surplus 
of £24.5m (5 April 2019 – deficit of £10.2m). 
The Group’s deficit reduction cash 
contributions, including administration costs, 
to the UK Plan ceased on 30 June 2022.
The estimated cash contributions expected to 
be paid during 2025 in the US funded plans is 
£0.4m (£0.4m was paid in 2024). 
Net debt
Net debt which includes IFRS 16 lease 
liabilities increased by £25.8m to £229.6m 
at 31 December 2024 (31 December 
2023 – £203.8m). As noted in the cash flow 
on the previous page, the Group generated 
net cash outflow of £9.8m (as defined in 
Note 31), before £3.1m adverse foreign 
currency movements and £12.9m non-cash 
changes in lease liabilities due to additions 
and modifications.
Net debt excluding IFRS 16 lease liabilities 
of £76.2m (31 December 2023 – £71.8m) 
increased by £21.4m to £153.4m at 
31 December 2024 (31 December 
2023 – £132.0m), due to free cash inflow 
of £17.3m and £3.0m dividend received from 
the Joint Venture being more than offset by 
£15.0m outflow for dividends and net purchase 
of shares, £13.0m cash outflow in respect 
of corporate undertakings, £10.0m capital 
repayment of leases, £2.1m net cash outflows 
for site relocation and restructuring and £1.6m 
adverse foreign currency movements.
Funding and Liquidity
As at 31 December 2024, the Group’s gross 
borrowings excluding leases and transaction 
costs directly attributable to borrowings 
were £200.0m (31 December 2023 – £181.0m), 
with 64% of the Group’s gross borrowings 
denominated in US Dollars (31 December 
2021 – 61%). Cash and bank balances were 
£45.5m (31 December 2023 – £47.6m). 
The maturity of these borrowings, together with 
the maturity of the Group’s committed facilities, 
can be analysed as follows:

At the year-end, the Group had committed 
facilities of £311.9m comprising private 
placement debt of £162.1m and revolving 
credit facilities of £149.8m. The Group is 
in a strong funding position, with headroom 
at 31 December 2024 of £158.5m in cash 
and undrawn facilities. 
In the first half, the US RCF of $50m was 
extended by a year and will now mature in 
June 2026. New private placement loan notes 
of $40m (£32m) were issued and drawn down 
in February 2025, carrying an interest rate of 
5.46% and are due for repayment in February 
2029. These new loan notes have refinanced 
the maturing £27m private placement loan 
notes that were repaid in January 2025.
The weighted average maturity of the Group’s 
committed facilities at 31 December 2024 was 
2.5 years.
The Group has £nil (2023 – £1.8m) of 
uncommitted borrowings which are repayable 
on demand. 
The Group has two covenants for committed 
borrowing facilities, which are tested at 
June and December: the Group’s net debt to 
EBITDA (defined in the Notes to the Financial 
Headlines on page 1) must not exceed 3.0x 
and interest cover, the ratio of EBITDA to 
interest must be higher than 3.5x. At 31 
December 2024, the Group’s net debt to 
EBITDA was 1.8x and interest cover was 7.0x, 
both comfortably within covenant limits.

VIABILITY STATEMENT
Following a robust assessment, the Directors have concluded 
that the Group and Parent Company have sufficient funds to 
operate for the foreseeable future (evaluated to 31 December 
2027), even in a severe but plausible downside scenario.
In Flexonics, ACT forecast North American 
heavy-duty truck production to decline by 5% 
in 2025 and rebound in 2026 to 12% growth 
as a result of the pre-buy ahead of the planned 
2027 emission change. S&P predict European 
truck and bus production to increase by 2% in 
2025. S&P is forecasting that light vehicle 
production in 2025 will fall by 5% in Europe, 
by 2% in North America and increase by 6% in 
India. The global land vehicle market is expected 
to grow at low single-digit compound annual 
growth rate through the cycle. In power and 
energy markets, activity in the downstream 
sector remains focussed in the Middle East and 
Asia, where cheap feedstock and economic 
growth respectively is driving demand. Global 
electricity consumption is forecast to grow at 
4% annually through 2027. Demand is being 
driven primarily by economic growth, 
urbanisation and the adoption of EVs.  
In determining a severe but plausible downside 
scenario, the base case projections are flexed to 
reflect the weighted probability and cumulative 
estimated effects of all the Group’s principal 
risks and uncertainties, as disclosed on pages 
54 to 59. This scenario reflects the combined 
probabilistic effect of all principal risks, rather 
than individual scenarios for each risk, according 
to impact and likelihood of occurrence and 
include mitigations where appropriate to 
maintain liquidity. These effects drive key 
metrics in revenue growth, operating profit 
margin and borrowing rates. The top 5 principal 
risks with the highest estimated effect on key 
metrics include Geopolitical and Economic 
impact, Cyber/Information Security, Supply 
Change Challenges, Implementation of Strategy 
and Price-Down Pressures. The remaining risks 
have relatively equal weighting in the scenario 
with Corporate Governance having the lowest 
estimated effect.
To address the impacts under the severe but 
plausible downside, the Board has considered 
the mitigating actions within the Group’s direct 
control. These include a continued focus on 
conserving cash through vigilant management 
of capital expenditure and working capital 
together with further restructuring actions and 
limiting non-critical discretionary spend.
Committed facilities and debt covenants 
At 31 December 2024, the Group held 
committed borrowing facilities of £311.9m with 
liquidity headroom of £158.5m. New private 
placement loan notes of $40m (£32m) were 
issued and drawn down in February 2025. 
These notes carry an interest rate of 5.46% and 
The Board has considered a three-year period, 
as this reflects the normal mid-term planning 
cycle of its business operations while 
adequately covering customer lead times for 
both new and expansion investment. In addition, 
this period provides sufficient clarity to consider 
the business prospects and continued recovery 
from the pandemic under a base case, while 
also assessing impacts under a severe but 
plausible downside scenario. 
Overall, the Board anticipates good growth for 
the Group in 2025 in line with its expectations. 
Increasing aircraft build rates, operational 
efficiency benefits and improved contract pricing 
are expected to drive good growth in Aerospace 
in 2025, with H2 performance expected to be 
higher than H1. For the full year, Aerostructures 
is expected to improve from a loss making 
position in 2024 to an operating profit range 
of £9m to £11m in 2025, with the large majority 
of that being earned in H2. We expect Flexonics 
performance in 2025 to be broadly similar 
to 2024. In land vehicles, the ramp up of 
programmes recently won means we expect 
our 2025 performance to be broadly similar to 
2024, despite some softness in North America 
and Germany. In power and energy, activity 
levels are expected to be similar to 2024.
The base case projections of the viability 
assessment are based on the Group’s Budget 
for 2025 and the Group’s Strategy for 2026 and 
2027. The civil aerospace sector continued its 
recovery with air traffic increasing in all regions 
during 2024. According to the International Air 
Transport Association (“IATA”), the latest data 
showed that total demand during the year, 
measured in Revenue Passenger Kms (RPKs), 
increased by 10% year-on-year. Air traffic is 
expected to continue to grow as incomes 
increase, especially in developing markets in 
Asia. The long-term demand for new aircraft is 
forecast to grow by 3-4% per annum driven by 
growth in air traffic and ongoing fleet 
replacement. With record order books, both 
Airbus and Boeing plan to increase their aircraft 
production rates over the coming years. In the 
Group’s other key markets, Senior’s sales to the 
Defence sector are primarily focused on US 
military aircraft platforms, with good content on 
the F-35 Joint Strike Fighter, the newer T-7A 
Red Hawk trainer programme, as well as mature 
programmes such as the C-130J. The total 
planned purchases of F-35s is over 3,500 
aircraft, of which 31% is for the international 
market and Lockheed Martin expects to 
produce 156 F-35 aircraft per year. 
are due for repayment in February 2029. The 
weighted average maturity of the Group’s 
committed facilities is 2.5 years. Net debt 
(defined in Note 31c) was £229.6m, including 
£76.2m of capitalised leases which do not form 
part of the definition of debt under the 
committed facilities and do not impact the 
Group’s lending covenants. 
The Group has two covenants for committed 
borrowing facilities, which are tested at June 
and December: the Group’s net debt to EBITDA 
(defined in the Notes to the Financial Headlines 
on page 1) must not exceed 3.0x and interest 
cover, the ratio of EBITDA to interest must be 
higher than 3.5x. At 31 December 2024, the 
Group’s net debt to EBITDA was 1.8x and 
interest cover was 7.0x, both comfortably 
within covenant limits. 
Board’s conclusion 
Modelling the base case and severe but 
plausible downside scenario and mitigations 
indicate that the Group is in compliance with all 
debt covenants at all measurement dates out to 
31 December 2027. The scenarios also highlight 
sufficient liquidity headroom throughout the 
period in light of the committed facilities 
available. Accordingly, following a robust 
assessment the Directors have concluded that 
the Group and Parent Company have sufficient 
funds to operate for the foreseeable future, even 
in a severe but plausible downside scenario. For 
the going concern assessment, the foreseeable 
future covers a minimum period of 12 months 
from the date of approval of these Financial 
Statements, and with the viability period 
evaluated out to 31 December 2027. 
Going concern 
As a consequence of the work undertaken to 
support the viability statement above, the 
Directors have, at the time of approving these 
Financial Statements, a reasonable expectation 
that the Group and Parent Company have 
adequate resources to continue in operational 
existence for the foreseeable future, being a 
period of at least 12 months from the date of 
approval of these Financial Statements. 
Accordingly, they continue to adopt the going 
concern basis of accounting in preparing these 
Financial Statements, having undertaken a 
rigorous assessment of the financial forecasts.

Independent Auditor’s Report to the 
Members of Senior plc
Ian King | Company Chair and 
Chair of the Nominations Committee
“On behalf of the Board, 
I am pleased to present 
the Senior plc Corporate 
Governance Report 
for the year ended 
31 December 2024.”

Dear Shareholder,
On behalf of the Board, I am pleased to present 
the Senior plc Corporate Governance Report for 
the year ended 31 December 2024. This is a 
period of change for the Company’s Board, and 
we continued our strong focus on governance 
practices during this time. The Board’s 
composition, independence and expertise 
remain appropriate for this period of transition, 
ensuring effective challenge and oversight.
Board changes
As announced on 15 May 2024, Bindi Foyle 
informed the Board of her intention to retire from 
a full-time executive career in May 2025. Bindi 
has been a part of Senior’s leadership team for 
the past 19 years and an accomplished Finance 
Director for almost 8 years. We would like 
to take this opportunity to thank Bindi for her 
outstanding contributions and commitment 
and wish her well for the future. As part of an 
orderly succession planning process, and after 
a thorough recruitment process, we appointed 
Alpna Amar as the Group Chief Financial Officer. 
Alpna will join the Board in April 2025 as an 
executive Director and will become the Group 
Chief Financial Officer in May 2025. Alpna brings 
a wealth of experience in our end markets 
and a strong track record of helping to enhance 
shareholder value. The Board is confident she 
will make a fantastic contribution to Senior for 
the benefit of all of our stakeholders.
Having reached her nine-year anniversary of 
serving on the Board of Senior, Susan Brennan 
will be retiring at the upcoming AGM of the 
Company. We thank Susan for her long-standing 
service and contributions to the Board, and we 
wish her all the best for the future. In compliance 
with the UK Corporate Governance Code 
and in line with our commitment to refresh the 
composition of the Board and to maintain its 
independence, we appointed Zoe Clements 
as a non-executive Director with effect from 
1 September 2024. Zoe’s direct experience 
in complex investment, private equity and 
finance roles across a variety of industries will 
complement the current Board and prove 
invaluable to Senior’s continued development.
Focus on diversity across leadership
In 2024, the Board maintained its focus on 
diversity. As at the time of this report, the Board 
includes 56% women, and two of our Board 
directors are from ethnic minority backgrounds. 
The Board remains committed to supporting 
the recommendations of the Parker Review to 
promote ethnic diversity. In 2024, we have set 
a target of 15%, to be achieved by December 
2027, in respect of the UK senior management 
positions within the Group that will be occupied 
by ethnic minority executives.
Sustainability governance
In response to the emerging regulatory 
landscape, the Board provided oversight over 
the Group’s Double Materiality Assessment 
(DMA). The results of the assessment, which 
evaluated sustainability-related impacts, risks 
and opportunities from financial and impact 
perspectives, will inform Senior’s approach 
to enhancing and evolving its sustainability 
strategy, aligning it to the changing external 
environment and long-term strategic priorities.
Employee engagement
In 2024, we conducted our third Global 
Employee Engagement Survey, which allowed 
us to gain insights into employee experiences 
within the Group and their connection to 
Senior’s Purpose and Values, and to identify 
areas for improvement. We are pleased to say 
that the Company has achieved an overall 
employee participation rate of 85% and an 
employee engagement score of 7.5. More 
information can be found on pages 28 and 29 
of the Strategic Report.
2025 Annual General Meeting (AGM)
The Company’s 2025 AGM will take place on 
25 April 2025 as a physical meeting at 59/61 
High Street, Rickmansworth, Hertfordshire, 
WD3 1RH. We invite you to attend the AGM, 
to meet the Board and our leadership team. 
The Board and I would like to thank you for 
your continued support throughout this year 
of significant change and your continued 
commitment to the Company.

To enable the members of the Board and its Committees to discharge their duties effectively, 
the Chair ensures that relevant and reliable information is provided to all Directors in a timely 
manner in advance of meetings. The Group Company Secretary supports the Board to ensure 
that it has in place appropriate policies, processes, time and resources to enable it to operate 
efficiently and effectively.
There is a procedure by which all Directors can obtain independent professional advice at the 
Company’s expense in furtherance of their duties, if required, and they have been made aware 
of this.
Role of the Board
Senior’s Board has the responsibility to promote 
the long-term and sustainable success of the 
Company, creating value and delivering positive 
outcomes for all stakeholders. It is also 
responsible for the Group’s strategic direction, 
financial and operational performance as well as 
an effective governance framework; it ensures 
that the necessary resources are in place for the 
Company to meet its objectives. A detailed 
description of the Board’s responsibilities is 
covered by the Matters Reserved for the Board 
and available on the Company’s website.
Our governance framework supports and 
promotes a culture of integrity, trust and 
accountability. Directors must avoid conflicts 
of interest that may arise when their personal 
interests conflict with those of the Company. 
Our approach to managing conflicts of interest 
is described on page 89. Directors should 
demonstrate zero tolerance for fraud, bribery 
and corruption. In 2024, we enhanced the 
Group’s fraud prevention framework by 
formalising the Group’s commitment through 
a Fraud Policy. The Policy was incorporated 
into the Group’s Corporate Framework, and it 
reinforced our commitment to ethical behaviour, 
respect and transparency across all of Senior’s 
operating businesses. Further information is set 
out on page 80. Directors promote a culture of 
open communication, where employees can 
express their opinions or concerns without a 
fear of retaliation. In 2024, as part of the Global 
Employee Engagement Survey, we held 
sessions with our Group employees where we 
listened to their feedback, giving them the 
opportunity to implement positive changes in 
their workplace. This year, we also took the 
opportunity to update our Code of Conduct. 
During its regular meetings in 2024, the Board 
considered the best way of addressing 
opportunities and mitigating risks to the future 
success of the Company. This was done as part 
of the Group-wide assessment of the principal 
risks, described on pages 50 to 59. Our annual 
Board Strategy meetings continued to provide 
an effective forum to review Senior’s 
competitive landscape, technological trends, 
changes in customer behaviour, as well as to 
consider existing and emerging opportunities 
to diversify the Group’s products in response 
to changing customer preferences. 
The table below sets out key focus areas for the Board during 2024. 
SENIOR PLC ANNUAL REPORT AND ACCOUNTS 2024

GOVERNANCE

Recognising that Senior’s Business Model 
must be resilient and sustainable, the Board 
provided oversight of the considerable work 
being done by the Company in identifying 
material sustainability-related impacts, 
risks and opportunities, as described on pages 
12 to 13. Integration of the Double Materiality 
Assessment insights into Senior’s strategic 
decision-making will enable the Company to 
better respond to emerging regulatory changes, 
enhance its reputation with stakeholders 
and promote innovation – all of which 
contribute to the long-term sustainability 
of the Business Model.
Throughout the year, governance supported 
effective delivery of the Company’s strategic 
priorities, as set out on pages 34 and 35. The 
Company’s progress in implementing the 
strategy is monitored through a set of financial 
and non-financial KPIs, details of which can be 
found on pages 48 and 49.
The Board is responsible for assessing and 
monitoring the Group’s culture. The expected 
behaviours and Values are communicated to all 
employees through our Code of Conduct; this is 
further supported by Group-wide policies and 
practices. The Group ensures that its workforce 
policies and practices align with the Company’s 
Values and support its long-term sustainable 
success. The disclosures on pages 27 to 29 
describe how our policies and procedures 
across the Group align with our Values.
The Board’s activities 
in monitoring culture
Qualitative reporting
•	 We hold some of our Board meetings at 
our operating business locations around 
the world, which provides an effective 
forum for employees to engage directly 
with Board Directors and to share their 
views. Presentations made by the 
operating businesses to Board directors 
provide further insights on culture, 
challenges and areas for improvement.
•	 Mary Waldner is our NED responsible for 
employee engagement, and she has 
provided feedback to the Board following 
her extensive engagement with the 
Group’s employees across multiple 
operating business locations.
Quantitative reporting
•	 Reviewing health & safety and training 
completion statistics.
•	 Reviewing diversity metrics across 
the Group.
Further information on the Company’s approach 
to investing and rewarding its workforce can be 
found on page 28.
Internal controls and risk management
The Board has ultimate accountability for the 
Group’s risk management process.
The Board determines the nature and extent 
of the actions necessary to achieve its strategic 
objectives and maintains an effective system 
of internal controls. The Company’s Audit 
Committee reports to and, for certain matters, 
advises the Board of Directors. The Audit 
Committee Report on pages 90 to 95 describes 
the role and activities of the Audit Committee, 
together with the significant risks and 
judgments that it considered in relation to the 
2024 Financial Statements and its relationship 
with the internal and External Auditors. Details 
of the Group’s approach to risk management 
and its Risk and Assurance Framework can be 
found on page 52.
Anti-bribery & corruption
Senior has a zero-tolerance policy for bribery 
and corruption. Senior’s Code of Conduct clearly 
states that Senior will follow all applicable 
bribery and corruption laws that apply in the 
countries where we do business, including the 
UK Bribery Act 2010 and the US Foreign Corrupt 
Practices Act. This principle is embedded in our 
Code and supported by four policies: Agents 
Policy, Gifts and Hospitality Policy, Fraud Policy 
and Whistle-blowing Policy. Employees are 
provided with training to raise awareness of the 
risks and potential consequences of corruption.
•	 Agents Policy
The Group recognises that the use of 
third-party intermediaries can increase 
potential bribery and corruption risks within 
the markets in which we operate. The 
Company conducts appropriate due diligence 
and ongoing monitoring of third parties with 
which it works, including regular screening, 
risk assessments and compliance health 
checks. The Company also subscribes to 
third-party rating organisations to support its 
due diligence process, particularly when 
appointing agents and distributors. The 
Group’s operating businesses are required to 
report on the agents and advisers appointed 
by them, on a biannual basis, to the Group 
Company Secretary. In addition, the Group 
Company Secretary must be notified when 
new agents are appointed. Biannual reporting 
is reviewed by the Audit Committee.
•	 Gifts and Hospitality Policy
The Board recognises that gifts and hospitality 
have the potential to create a conflict of 
interest, or the perception of a conflict 
of interest. The Gifts and Hospitality 
Policy – which restricts the receiving and 
giving of gifts and hospitality from, and to, 
third parties – requires that all gifts and 
hospitality must be recorded annually through 
a self-declaration process. Employees must 
declare any gift or hospitality provided or 
received with the individual or annual 
aggregate value in excess of £200 (or a lower 
amount as notified by the Company 
Secretary) as specified in the Group Gifts 
and Hospitality Policy. Internal audits assess 
adherence to the Group’s Gifts and Hospitality 
Policy during audits conducted throughout the 
year and the annual controls self-assessment.
Alignment between Senior’s Purpose, Values, culture and strategy
Purpose 
We help engineer transition to a 
sustainable world for the benefit of all 
our stakeholders.
The Company’s Purpose is aligned 
with our strategic focus on fluid 
conveyance and thermal management, 
the support to our customers in 
transitioning to low-carbon and 
clean energy solutions, and to our 
commitment to stay at the forefront 
of climate disclosure and actions, 
including our Net Zero commitments.
Values and Culture
Safety, Integrity, Customer Focus, Respect 
and Trust, Accountability, Excellence
Values define behaviours and practices 
expected from Senior’s employees in their 
business relationships with internal and 
external stakeholders. Values guide the 
Company’s culture, aligning daily actions 
with the long-term strategy. They are 
integrated into employees’ performance 
reviews, reinforcing the culture where 
values are actively practiced and supported.
Strategy
The Company strategy is reviewed on 
an annual basis, allowing the Board to 
assess performance, adjust priorities 
and make informed decisions to drive 
long-term sustainability.

BOARD LEADERSHIP AND COMPANY PURPOSE CONTINUED
•	 Fraud Policy
Fraud can lead to financial, operational, 
legal and reputational damage and, ultimately, 
may affect the achievement of the Group’s 
strategic long-term goals, objectives and 
priorities. The Group’s Fraud Policy defines the 
critical elements of Senior’s fraud 
management programmes and establishes 
clear expectations for anti-fraud responsibilities 
across the Group. The Audit Committee is 
responsible for reviewing fraud instances 
within the Group and ensuring that proper 
controls are implemented and maintained 
to prevent any further fraudulent activities.
•	 Whistle-blowing Policy
As part of our commitment to operate 
ethically, the Company has a Whistle-blowing 
Policy that is communicated throughout the 
Group. This Policy provides employees and 
other stakeholders the opportunity to report 
suspected unethical or illegal corporate 
conduct confidentially and anonymously. 
Senior will not tolerate the harassment or 
victimisation (including the application of 
informal pressure) of a person reporting 
corporate conduct in good faith. In addition 
to the legal protection provided to such 
persons, Senior will treat retaliation against 
a person reporting corporate misconduct 
as a violation of this Policy and a serious 
disciplinary offence.
The Group encourages individuals to first raise 
their concerns, verbally or in writing, with a line 
manager, an HR team member or local operating 
business leader. Where local reporting is not 
appropriate, individuals can report their concerns 
to a Divisional CEO. Alternatively, anonymous 
written, electronic or telephonic communications 
may be submitted to any of the above-named 
parties. Where a person feels uncomfortable or 
unable to approach any of the parties mentioned 
earlier, or if the person feels an investigation was 
not concluded in accordance with local policy or 
regulations, they should contact Senior’s 
third-party free whistle-blowing service provider 
by telephone or via the web reporting tool. 
This service includes the ability to report in 
multiple languages.
The provider will pass the details of the concern 
to a designated individual from Senior based at 
our Group head office in the UK to allow for a full 
investigation of the matter. Where requested, 
the provider will not pass on the personal 
details of who has made the disclosure if the 
individual(s) requested that their personal details 
be withheld. All whistle-blowing reports are 
investigated under the terms of strict 
confidentiality to the fullest extent possible. 
The investigator will ensure that the 
investigation is undertaken as quickly as 
possible and conducted within the timeframe 
required by local regulations. On conclusion of 
the investigation, the whistle-blower is informed 
of the outcome of the investigation and what 
action Senior has taken, or proposes to take, 
as a result of the investigation.
The Group Company Secretary provides 
information on any reported whistle-blowing 
cases in regular secretarial reports to the 
Board of Directors. This is a standing agenda 
item at every Board meeting. In addition, the 
Group HR Director summarises the total cases 
and assesses if any patterns or trends are 
emerging. This is included in every Group Chief 
Executive Officer’s report to the Board. The 
Director of Risk and Assurance provides 
whistle-blowing case information in her report 
to the Audit Committee.
Human rights and modern slavery
The Group’s Human Rights Policy, which can be 
found on the Company’s website, sets out the 
standards we expect from our employees, 
customers and suppliers regarding human 
rights. At Senior, we strive to do business in a 
responsible way, respecting the human rights of 
our workers and everyone we come into contact 
with. We also expect our suppliers to respect 
and adhere to the Policy. The Group recognises 
the importance of the Universal Declaration of 
Human Rights and adheres to the core principles 
and values defined within it. The majority of 
countries in which Senior operates have their 
own laws banning child labour and promoting 
human rights. Senior monitors the ages of its 
workforce across the world to ensure 
compliance and identify any potential issues.
Senior is committed to preventing slavery and 
human trafficking in its corporate activities and 
throughout its supply chain. Senior does not 
restrict any of its employees in any of the 
countries in which it operates from joining a 
trade union if they wish to do so. Senior also 
works closely with its suppliers to ensure that 
they at least meet internationally recognised 
minimum requirements for workers’ welfare 
and conditions of employment. Senior publishes 
the Modern Slavery Act Statement, which is 
kept under review and updated as necessary. 
The current statement can be found on the 
Company’s website.
Sustainable Sourcing Policy
Senior’s Sustainable Sourcing Policy defines the 
environmental, ethical and social responsibility 
principles that all Group suppliers must adhere 
to. The Policy applies to all key suppliers of 
goods and services based on annual spend and 
certain risk factors, such as country of origin 
and/or the nature of supply or service. All 
suppliers must be screened in accordance 
with the Policy, local trade compliance and 
sanctions regulations, as well as other relevant 
Group policies prior to engaging in any 
procurement activities.
International trade compliance
Senior will conduct its business in full 
compliance with all global trade laws and 
regulations and all relevant sanctions for the 
import and export of goods and services in 
the countries within which it operates. This 
Principle of the Code of Conduct is supported 
by the Contract Review Policy, Local Export 
Compliance Programmes and the Whistle-
blowing Policy.
Cyber security and data protection 
Cyber security is critical to the long-term 
sustainability of the Group’s success, and we 
maintained strong focus on this area.
The Group has in place the Information Security 
Strategy, which provides assurance that there is 
sufficient focus on reducing risks of significant 
cyber attacks. The Group’s Information Security 
Policies are based upon a number of recognised, 
international standards, including ISO 27001, 
NIST Cyber Security Framework and the CIS top 
20 controls, and all Group operating businesses 
are required to follow the Policies.
The Board of Directors has overall responsibility 
over the Group’s cyber security, ensuring that 
the Group remains resilient against cyber risks. 
In 2024, the Group Director of Information 
Security & Information Technology updated the 
Board on the progress against the Group’s 
Information Security Strategy and security 
issues identified during the year, and presented 
the 2023-2026 Capability Roadmap that 
identified specific cyber security-related 
capabilities that needed to be developed 
to support the delivery of the Information 
Security Strategy. 
The executive responsibility for both Information 
Technology (IT) and Information Security (IS) are 
consolidated under a single individual; this 
approach ensures clear accountability and more 
robust risk management. Information security 
risk assessments are regularly conducted across 
the Group. Risks identified by subject matter 
experts are reviewed with applicable risk 
owners and steps agreed to mitigate. Further 
information on how we manage cyber/
information security risk can be found on page 
56. In 2024, we continued various initiatives 
designed to enhance employees’ awareness of 
the risks posed by phishing emails, helping them 
identify common traits of such emails and 
conducting simulated phishing exercises. In 
addition, we educated employees on healthy 
cyber security culture, as well as the benefits 
and risks posed by artificial intelligence.

GOVERNANCE

The Group has established mechanisms to 
ensure compliance with specific regulatory 
requirements. An Acceptable Use Policy is in 
place to provide guidelines for the acceptable 
and appropriate use of the Group’s information 
technology and operational technology assets 
by all Group employees. The Policy sets out the 
controls that are in place to help reduce the risk 
associated with the inappropriate use of the 
Group’s information technology and operational 
technology assets, which could lead to data 
loss, manufacturing disruption, virus or malware 
infection or other issues that could have a 
negative financial or reputational impact on the 
Group. In compliance with the Data Protection 
(Charges and Information) Regulations 2018, 
the Company is registered with the Information 
Commissioner’s Office. 
To ensure compliance with the General Data 
Protection Regulations (“GDPR”), both in the EU 
and the UK, the Company and all relevant Group 
operations have in place a GDPR policy and 
breach incident procedure which have been 
communicated to their employees. As the 
Company is not a public authority, its core 
activities do not require regular and systematic 
monitoring of individuals on a large scale and it 
does not process special categories of personal 
data, criminal convictions or offences data on a 
large scale; it is therefore not required to appoint 
a data protection officer. However, the Company 
and relevant Group operations each have a Data 
Protection Champion, whom employees can 
approach for guidance if they have any queries 
or concerns relating to data protection. 
Compliance with data protection regulations will 
continue to be monitored on an ongoing basis.
Engagement with stakeholders
A detailed description of the Board’s 
engagement with its stakeholders can be found 
in the Stakeholder Engagement section of the 
Strategic Report, on pages 40 to 45. 
Barbara Jeremiah, the Chair of the Remuneration 
Committee, engaged with the Company’s 
shareholders and employee representatives on 
remuneration-related matters. Further details can 
be found on page 97.
As part of the Double Materiality Assessment 
process, we have engaged with a wide range of 
stakeholders, including customers, suppliers and 
shareholders; in addition, we have used insights 
received from the 2024 Global Employee 
Engagement Survey. Further details on this 
engagement process can be found on page 13.
Mary Waldner is the Director designated to 
engage with the Group’s employees. The Board 
believes that Mary is well-suited to lead on the 
initiatives around employee engagement. 
Mary’s excellent communication skills and 
empathy with diverse employee perspectives 
have helped establish trust and form strong 
connections with the workforce. In addition, 
Mary’s background in the engineering sector 
has helped instil credibility with employees 
and their challenges. 
The Board considers various factors when 
assessing the effectiveness of its engagement 
mechanisms with the Group’s stakeholders. 
Participation rates in employee engagement 
activities, employee satisfaction rates and nature 
of feedback received from shareholders, nature 
and frequency of whistle-blowing reports are 
some examples that the Board uses to measure 
the effectiveness. The Board remained 
confident in the effectiveness of the Group’s 
engagement mechanisms and will continue its 
commitment to sustaining and adapting, where 
necessary, its approach.
The statement of compliance with Section 172 
can be found on pages 46 and 47.

Board leadership
Senior’s Board is led by Ian King, the non-
executive Chair, who was independent upon 
appointment as Chair of the Company in 2018. 
As at 31 December 2024, the Board comprises 
the Chair, six independent non-executive 
Directors and two executive Directors. 
All Directors were selected for appointment 
because of their wide industrial and commercial 
experience. The Board considers that all 
non-executive Directors of the Company 
continue to be independent, having taken into 
account a list of relationships and circumstances 
that may appear relevant in determining 
independence. Details of the members of the 
Board and of the Executive Committee can be 
found on pages 74 to 77.
Division of responsibilities
The Directors are confident that an effective 
Board is in place, with a clear division of 
responsibilities between the running of 
the Board and the running of the Group’s 
operating businesses. 
During 2024, the Chair held confidential 
meetings with non-executive Directors, 
without the executive Directors being present, 
in accordance with good practice. The Senior 
Independent non-executive Director met with 
the non-executive Directors to appraise the 
Chair’s performance in 2024.
Time commitments 
The Board regularly reviews time 
commitments of its non-executive Directors to 
ensure they can dedicate sufficient time to the 
fulfilment of their roles with the Company. 
To prevent overboarding, the Board regularly 
reviews external directorships; this approach 
is also integrated into the recruitment process. 
In 2024, the Board approved the appointment 
of Zoe Clements as a non-executive Director. 
During the short-listing process, the Board 
noted Zoe’s existing Board roles and remained 
satisfied that her availability and the ability to 
meet the time commitments required were 
appropriate. The Board undertakes its annual 
performance review which, among other 
matters, considers the performance of Board 
Directors, including their participation in and 
contribution to Board meetings.

Governance structure
The Board delegates a certain number of its 
responsibilities to the Audit, Remuneration 
and Nominations Committees.
There are procedures in place to ensure that all 
Directors are properly briefed, so that decisions 
taken by the Board are based on the fullest, 
up-to-date, available information. 
Other committees are appointed by the Board 
to deal with treasury matters, disclosure matters 
and specific matters such as acquisitions 
and disposals.
HSE Committee 
The HSE Committee is appointed by the 
Executive Committee; it oversees all health, 
safety and environmental matters across the 
Group. Its Terms of Reference can be found on 
the Company’s website. The Committee met 
three times during the year, and there was full 
attendance at every meeting. In 2024, the 
Committee Chair provided feedback to the 
Board after each meeting, and minutes arising 
from all HSE Committee meetings were made 
available to the Board. In addition, the Group

COMPOSITION, SUCCESSION 
AND EVALUATION
Dear Shareholder,
On behalf of the Board, I am pleased to present 
the Nominations Committee Report for the year 
ended 31 December 2024.
Board and Executive 
leadership succession
In 2024, the Committee continued its focus 
on succession planning. Following the 
announcement of Bindi Foyle’s retirement from 
the Board, the Committee worked closely with 
the management and the executive search 
consultants to identify potential candidates for 
the role. As announced in November 2024, 
Alpna Amar will succeed Bindi, joining the Board 
as an executive Director in April 2025, and will 
become Group Chief Financial Officer when 
Bindi retires in May 2025.
The Committee was mindful that Susan 
Brennan would be approaching the end of her 
nine-year appointment to the Board in January 
2025; therefore, it led the succession planning 
process to recruit an additional non-executive 
Director. We announced the appointment of 
Zoe Clements to the Board of Directors with 
effect from 1 September 2024. Susan Brennan 
will be retiring from the Board and as a member 
of the Audit, Nominations and Remuneration 
Committees at the conclusion of the 
Company’s next AGM in April 2025.
Throughout the year, the Committee also 
maintained emphasis on executive leadership 
succession planning to ensure the continuity of 
strong and effective leaders across the Group. 
Jane Johnston, the Group HR Director, 
announced her intention to step down from the 
role in the second quarter of 2025, and the 
Nominations Committee supported the Group 
Chief Executive Officer in the selection process 
for this role.
Induction process for new 
non-executive Directors
The induction process for new non-executive 
Directors is crucial in helping them understand, 
among other matters, the Company’s business, 
culture and key stakeholders. Joe Vorih and Zoe 
Clements, two of our most recently appointed 
non-executive Directors, have undergone a 
structured induction programme, including 
meetings with members of the Executive 
Committee and visiting Senior’s operating 
businesses. This enhancement to our induction 
programme is a follow-on action from the 
previous Board Effectiveness Review, and it 
will be maintained for all future non-executive 
appointments to ensure consistency and 
comprehensiveness of the onboarding process.
Board and senior management diversity
Maintaining and enhancing the diversity of the 
Board remained a priority throughout the year. 
At the time of writing this report, the Board 
comprises 56% female directors and two 
ethnically diverse directors. Recognising the 
importance of building a strong diversity pipeline 
throughout all levels of the organisation, the 
Committee approved the target of 15%, to be 
achieved by December 2027, in respect of the 
Group’s UK senior management positions that 
will be occupied by ethnic minority executives.
Board performance review
An internal Board performance review was 
conducted during the year; further details 
can be found on page 88.

by the Nominations Committee and signed

REPORT
Responsibilities
The Company’s Nominations Committee leads 
the process for Board appointments and 
supervises leadership development and 
succession planning. It also makes 
recommendations to the Board on all new Board 
appointments and re-appointments. Primary 
responsibilities of the Committee include:
•	 reviewing the structure, size and composition 
(including the skills, knowledge, experience 
and diversity) of the Board, and making 
recommendations to the Board with regard 
to any changes;
•	 ensuring plans are in place for orderly 
succession to Board and senior management 
positions, and overseeing the development 
of a diverse pipeline for succession;
•	 keeping under review the leadership needs 
of the organisation (both executive and 
non-executive) with a view to ensuring the 
continued ability of the organisation to 
compete effectively in the marketplace;
•	 identifying and nominating for the approval 
of the Board, candidates to fill Board 
vacancies as and when they arise;
•	 leading the process of Board appointments;
•	 reviewing the time required from 
non-executive Directors; and
•	 reviewing the results of the Board 
performance evaluation process that 
relate to the composition of the Board 
and succession planning.
The Nominations Committee’s Terms 
of Reference can be found on the 
Company’s website. 
Re-election of Board Directors
The Nominations Committee and the Board 
consider that all non-executive Directors are fully 
independent and free from any conflicts of 
interests that could hinder their ability to perform 
their duties effectively. Senior considers its 
non-executive Directors are actively contributing 
their diverse experiences and expertise from 
various industry sectors. Any potential conflicts 
of interest are fully disclosed by Directors upon 
appointment and are reviewed regularly 
throughout each year.
Details of the Directors’ external statutory 
appointments can be found in their biographies 
on pages 74 to 76. The Board believes that the 
Directors’ experience of working with other 
companies adds value to their contribution to 
the Company’s Board and Committee meetings. 
The Directors believe that the Board and its 
Committees have the appropriate combination 
of skills, experience and knowledge to enable 
them to perform their duties effectively. 
Membership of the Board and its Committees is

INFORMATION

NOMINATIONS COMMITTEE REPORT CONTINUED
The Board confirms that in 2024 all Directors in 
office at the time worked assiduously and 
diligently. Each Board member made a very 
positive contribution to the running of the 
Company and the Board confirms that they will all 
continue to work to ensure its long-term success.
In compliance with the Corporate Governance 
Code, all Directors, with the exception of Susan 
Brennan, will offer themselves for re-election at 
the 2025 AGM. Having reached her nine-year 
tenure on the Board of Senior, Susan will be 
retiring following the conclusion of the AGM 
and will not be standing for re-election. Zoe 
Clements, who was appointed to the Board in 
September 2024 and Alpna Amar, who will join 
the Board in April, will stand for election at the 
AGM to be held in April 2025. The resolutions to 
be put to shareholders at the 2025 AGM can be 
found in the Notice of Annual General Meeting, 
which is available on the Company’s website.
Appointments to the Board
The Company follows a rigorous, formal 
and transparent procedure for its Board 
appointments, which is conducted in 
accordance with the Board Diversity and 
Inclusion Policy. New appointments are made 
on merit, taking account of the specific skills 
and experience, independence and knowledge 
needed to ensure a rounded Board, with 
diverse and inclusive Board and Committee 
composition. The Committee only engages with 
executive recruitment firms that have signed up 
to the Voluntary Code of Conduct for Executive 
Search Firms. 
Board induction and development
All Directors receive induction upon joining the 
Board and are encouraged to update their 
knowledge and skills on a frequent basis. 
The induction process typically includes the 
following key elements:
•	 introduction to the Company’s business;
•	 governance structure;
•	 legal compliance and Group policies;
•	 information on Group strategy;
•	 financial information;
•	 meetings with the Chair and 
non-executive Directors;
•	 meetings with the executive Directors and 
members of the Executive Committee; and
•	 site visits.
In 2024, we retained Sam Allen Associates Ltd, an executive search consultancy firm, 
to support with the recruitment of Group Chief Financial Officer and an additional 
non-executive Director. Sam Allen Associates is a member of the Standard Voluntary Code 
of Conduct for Executive Search Firms. The firm has no connection to the Company or any 
individual Directors.
Appointment process for 
Group Chief Financial Officer
The Committee worked closely with the 
executive leadership to define the experience, 
skills and competencies required for the role 
of Chief Financial Officer. The recruitment 
process carefully considered both external 
candidates, as well as the Group’s internal 
talent, drawing on the established succession 
plans and talent mapping. 
All candidates went through a strict 
referencing process. Following the conclusion 
of the interviews, Alpna Amar was identified 
as the most suitable candidate for the role of 
Group Chief Financial Officer. Her 
appointment was announced on 6 November 
2024. The Committee noted that Alpna 
would retain her role as a non-executive 
director of Chemring Group PLC, a FTSE 
250 listed company. The Committee 
considered this role in the context of the 
UK Corporate Governance Code, 
overboarding considerations and policies of 
key shareholders and proxy advisory firms, 
as well as the potential impact on Alpna’s 
role as an executive Director and Group 
Chief Financial Officer of the Company. 
Having given due consideration to all factors, 
the Committee was supportive of Alpna 
continuing her non-executive director’s role.
Appointment process for an 
additional non-executive Director
Recognising that Susan Brennan would be 
approaching the end of her nine-year 
appointment to the Board in January 2025, 
the Committee started an orderly recruitment 
process for an additional non-executive 
Director. Due consideration was given to the 
skills, experience and expertise required to 
maintain the diversity of the Board. Following 
an extensive selection process, the 
Committee recommended Zoe Clements as 
a preferred candidate to the position. Zoe’s 
direct experience in complex investment, 
private equity and finance roles across a 
variety of industries will complement the 
current Board and prove invaluable to 
Senior’s continued development.
Joe Vorih’s and 
Zoe Clements’ induction
Joe’s and Zoe’s induction process 
consisted of several steps. In the first 
instance, both Directors received Senior’s 
Induction Pack which provided, among 
other matters, contextual background of 
the Group’s operating environment, its 
strategic aspirations and performance.
The next element of Joe’s and Zoe’s 
induction included meeting with the Chair 
and representatives of senior management. 
The purpose of these sessions was to get 
a deeper understanding of any ongoing 
projects, stakeholder expectations, 
challenges and opportunities facing the 
Group; these informal meetings were also 
key to building relationships and rapport 
with internal stakeholders.
Finally, as part of their induction process, 
both Joe and Zoe have visited multiple 
Group operating businesses. These visits 
allowed Joe and Zoe to gain a better 
understanding of the broad range of 
products manufactured by Senior’s 
operating businesses and their contribution 
to and alignment with the overall Group 
strategy, key customer expectations 
and supplier relationships.
Directors receive training throughout the year, 
and the Group Company Secretary provides the 
Board with statutory and regulatory updates at 
every Board meeting and notifies them of any 
pressing points that are relevant between 
meetings. We recognise the importance of 
providing regular training to the Board Directors 
– this ensures they are well-equipped with the 
skills and competencies to fulfil their role 
effectively as the business and operating 
landscapes evolve. In 2024, the Directors 
completed the following training modules:
•	 Insiders and Insider Dealing;
•	 Accounting and Financial Integrity;
•	 Global Fraud Prevention;
•	 2024 Global Code of Conduct;
•	 Prevention of Facilitation of Tax Evasion;
•	 Cyber Security Training for Leadership;
•	 Preventing Sexual Harassment; and
•	 AI: Understanding its Use, Risk and 
Limitations in the Workplace.

Succession planning
Effective succession planning plays a key role in 
maintaining continuity of leadership, strategic 
oversight and decision-making. In 2024, the 
Committee received two scheduled updates on 
the Group’s succession plans from the Group 
Chief Executive Officer and the Group HR 
Director. The plans, which focused on the 
Executive Committee, their direct reports, and key 
divisional and Group roles, mapped out candidates 
capable of stepping into critical roles. This 
approach ensures that the Group can respond 
effectively to unexpected changes in leadership 
and maintain operational performance.
The Committee maintained its focus on 
reviewing individuals on the succession maps 
using the nine-box matrix, assessing employees 
based on two key dimensions – performance 
and potential. The matrix served as a starting 
point for discussions on development needs for 
the individuals shown on the matrix. When 
reviewing succession plans, the Committee 
acknowledged the benefits of a diverse 
workforce, diversity of thought and employing 
individuals from diverse backgrounds and 
experience across the organisation, including 
Board members and senior managers.
In 2024, we continued with our leadership 
development programme – “Leading for 
Excellence”. “Leading for Excellence” enables 
individuals to develop a number of critical 
competencies, particularly in the areas of 
leadership, stakeholder management and 
people management skills. The “Leading for 
Excellence” programme supports the 
Company’s focus on developing and nurturing 
those individuals who are capable of taking on 
leadership roles in the future.
In 2024, we also introduced a mentoring 
programme where members of the Board and 
the Executive Committee were mentoring high 
potential individuals, identified through the 
succession planning process.
The Committee remained satisfied with the 
evolution and progression of the succession 
planning process and was supportive of the 
initiatives to prepare high potential employees 
for future leadership roles.
Board diversity and inclusion
The Board Diversity and Inclusion Policy 
provides an effective framework for the 
Nominations Committee and the Board to 
follow in assessing the composition of the Board 
and its Committees and recommending the 
appointment of new Directors. The Company 
is committed to maintaining and promoting all 
aspects of diversity, inclusion and equal 
opportunity among the members of its Board 
and its Committees.
The Policy supports the Company strategy 
in several ways. A diverse Board brings 
a variety of perspectives, experiences and 
viewpoints, improving strategic discussions 
and decision-making. It helps the Company 
to maintain its agility, adapt to change more 
quickly, take advantage of emerging 
opportunities and find innovative approaches 
to address any challenges.
The objectives of the Policy in force for the year 
ended 31 December 2024 include:
•	 maintaining no less than 40% of female 
representation on the Board, including having 
at least one female director in a senior Board 
position (Chair, CEO, Senior Independent 
Director or Chief Financial Officer);
•	 maintaining no less than one director from 
a minority ethnic background on the Board;
•	 embedding diversity and inclusion principles 
into the recruitment process for Board 
appointments and succession planning by 
only engaging with executive recruitment 
firms that have signed up to the Voluntary 
Code of Conduct for Executive Search Firms; 
and
•	 working with executive recruitment partners 
to widen the pool of candidates by considering 
candidates from diverse backgrounds.
As at 31 December 2024, the Board has met all 
of the objectives set by the Policy.
In addition, we confirm that the Company has 
met the targets stipulated in the Listing Rule 
6.6.6R (9) as at 31 December 2024. The 
numerical data on the ethnic background and 
the gender identity of the individuals on the 
Board of the Company and in its Executive 
Committee as at 31 December 2024 is set out 
on page 73. As announced on 6 November 
2024, Alpna would join the Senior plc Board in 
April 2025 as an executive Director and will 
become Group Chief Financial Officer in May 
2025. In addition, Silvia Schwark will replace 
Jane Johnston as the Group HR Director in early 
2025. Data used for the purpose of making the 
disclosures was collected through the 
Company’s diversity monitoring forms 
completed by the individuals on the Board of the 
Company and in its Executive Committee.
The information on the gender balance of those 
in senior management and their direct reports 
can be found on page 27.
In 2023, we set a target of 30%, to be achieved 
by December 2027, in respect of the Group’s 
senior management positions that will be 
occupied by ethnic minority executives. At the 
end of 2024, ethnic minority representation 
among the Group’s global senior management 
positions was 23%.
This year, following the revised 
recommendations of the Parker Review, 
we set a new target of 15%, to be achieved by 
December 2027, in respect of the Group’s UK 
senior management positions.
Case study
EMPOWERING AND 
ELEVATING TALENTED 
WOMEN AT SENIOR
We are committed to providing a diverse 
and inclusive workplace, and we believe 
there remains an opportunity to further 
improve our gender diversity, particularly 
in our operating businesses by 
developing more women into leadership 
roles. To help us achieve this, we have 
established Senior’s Women’s Network 
which aims, among other matters, 
to support women by identifying, raising 
awareness of and addressing barriers for 
women in the workplace. The Network 
will provide opportunities for professional 
development and networking, helping 
women build confidence and skills to 
progress in their careers. We recognise 
that the Network’s outcomes may not 
be immediately evident; instead, 
we believe it will be able to create a 
longer-term organisational change, 
leading to increased representation of 
women in Senior’s operational roles.

Board performance review
2023 Board performance review findings and the progress made in 2024
Continue the focus on Board skills and succession; 
strengthen the induction process for new Board members 
with emphasis on Senior’s strategy, products and 
technology awareness, including site visits.
There had been good progress with Board succession, with the appointments 
to the Board of Joe Vorih and Zoe Clements, and to the Executive team 
of Alpna Amar and Silvia Schwark; changes to the induction process 
for new Board members would be made based on feedback received.
Adopt a more formalised structured agenda and broader 
role for the Nominations Committee, to enhance its 
oversight of succession planning, approach to training, 
development and talent.
The Nominations Committee oversaw the recruitment of two new 
Board members and of two executives.
Continue to streamline Board processes by making 
the Board meeting packs more concise.
Board processes continued to be reviewed including considering ways 
to make the Board meeting packs more concise.
Provide further opportunities for the Group employees 
to engage with and meet the members of the Board.
Further opportunities were provided for Group employees to engage with 
and meet the members of the Board, including during site visits and through 
the new Group Mentoring programme.
How the 2024 Board performance review has been conducted
The 2024 Board performance review was carried out internally through the use of online questionnaires. The scope of the questionnaires covered 
the Board as well as the Audit, Remuneration and Nominations Committees. Areas covered by the questions included quality and quantity 
of information being provided to the Board and its Committees, composition and any gaps in characteristics, experience or skills, quality of 
discussions around strategic issues and other challenges facing the Company and relationship with the executive leadership, among other matters.
Following the completion of questionnaires by all Board Directors and the Company Secretary, a consolidated report was presented to the Board.
The outcomes and actions taken
Overall, the Board performance review concluded that the Board had exercised strong governance and was operating effectively. The recruitment 
of Joe Vorih and Zoe Clements had addressed Board succession requirements and complemented the Board skills.
Board sessions had a good level of challenge and discussion, with appropriate and constructive input from non-executive Directors. The Board 
Committees were all considered to be working effectively.
The Chair was committed and fully engaged in the discussions taking place both within and beyond Board meetings. Barbara Jeremiah and Mary 
Waldner continued to be effective in their respective committee Chair roles. Barbara and Mary were also effective in their respective roles as the 
Senior Independent non-executive Director and the designated non-executive Director for employee engagement.
The Board is committed to regular training, in particular on Cyber and a yearly refresh on Code of Conduct, with all Board members up-to-date 
on requirements.
The Board agreed the following focus areas for 2025: 
•	 the Nominations Committee would continue its focus on Executive succession and look to drive further improvements in the Group’s gender 
diversity, particularly within the operational management teams;
•	 having defined the Fluid Systems strategy in 2024, the Board would continue to discuss and stress test the strategy, and oversee the 
implementation of the strategy and operational improvements;
•	 increase the amount of time the Board spends considering market developments affecting the Group, including customer activity and supply 
chain issues; and
•	 following the succession of the Group CFO and Group HR Director, ensure that their inductions are effective, that they build strong relationships 
with the respective Chairs of the Audit and Remuneration Committees, and that they drive further improvements in Organisation efficiencies.

Authority to purchase the Company’s 
own shares
The Company purchased no ordinary shares of 10 
pence each in the capital of the Company; 4,148,205 
shares in the Company (2023– 3,234,988 shares) were 
purchased by the Senior plc Employee Benefit Trust in 
the year to satisfy the future vesting of executive share 
awards and employee share plans. At the end of the 
year, the Directors had authority, under a shareholders’ 
resolution dated 26 April 2024, to make market 
purchases of the Company’s shares up to an aggregate 
nominal amount of £42m (2023 – £42m), which 
represented approximately 10% of the issued share 
capital of the Company. A resolution to renew this 
authority will be proposed at the forthcoming AGM.
Disclosure of information to auditor
Each of the persons who is a Director of the Company 
at the date of approval of this Annual Report & 
Accounts confirms that so far as the Director is aware, 
there is no relevant audit information of which the 
Company’s Auditor is unaware; and the Director has 
taken all steps that he/she ought to have taken as a 
Director in order to make himself/herself aware of any 
relevant audit information and to establish that the 
Company’s Auditor is aware of that information. 
This information is given and should be interpreted in 
accordance with the provisions of Section 418 of the 
Companies Act 2006.
In 2016, the Group undertook a formal tender process 
for its external audit function, which resulted in KPMG 
LLP being appointed the Group’s External Auditor for 
the financial year commencing 1 January 2017. KPMG’s 
re-appointment was last approved by the Company’s 
shareholders at the 2024 AGM. In accordance with

for the re-appointment of KPMG LLP as Auditor of the 
Company is to be proposed at the forthcoming AGM. 
During the second half of 2024 the Board, with the

of the Company, such as commercial contracts, bank 
loan agreements, property lease arrangements, and

to be significant in terms of their likely impact on the 
business of the Group as a whole. Furthermore, the 
Directors are not aware of any agreements between 
the Company and its Directors or employees that 
provide for compensation for loss of office or 
employment that occurs because of a takeover bid. 
Conflicts of interest
The Board has a procedure for identifying and 
managing Directors’ potential conflicts of interest. 
The Group Company Secretary maintains the Register 
of Directors’ Potential Conflicts of Interest. Directors 
are required to declare their own potential conflicts, 
together with those of their close family members, 
their partners, any trust to which they are a beneficiary, 
a corporate body in which they have a 20% interest 
or above, or a firm in which they are a partner. The 
Directors review and confirm their Register entries at 
least annually. At every Board meeting, the Directors 
are required to declare if they have any potential 
conflicts of interest in the business to be discussed at 
the meeting. In 2024, the Directors confirmed there 
were no potential or actual conflicts of interest.
Directors’ indemnities 
Qualifying third-party indemnity provisions for the 
benefit of the Directors were renewed by the 
Company during the year and remain in force at the 
date of this Report.
Research and design
In 2024, the Group incurred £20.0m (2023 – £20.0m) 
on research and design. Product development 
and improving manufacturing processes represent 
the primary focus of the Group’s research and 
design activities.

No political donations were made by the Company

of Senior’s Business Model, strategic priorities, financial 
and non-financial key performance indicators, risks and 
uncertainties, market overview, key growth drivers and 
a summary of the Group’s 2024 performance.

(2023 – 0.60 pence) has already been paid and 
the Directors recommend a 2024 final dividend of

Committee’s Terms of Reference were updated 
in December 2024, reflecting the changes 
introduced by the UK Corporate Governance

accounting standards and statements of 
recommended practice;

The Audit Committee held a private meeting with the External Auditor and a private meeting with the Group’s Director of Risk and Assurance on
31 July 2024 and 25 February 2025, without executive management being present. In addition, the Chair of the Audit Committee held separate 
meetings with each of these during the course of the year.
In addition to the four scheduled meetings summarised above, an additional Audit Committee meeting was held in April 2024, to approve the draft 
Trading Update for the three-month period ended March 2024; the latter being subject to final confirmation by the Disclosure Committee. 
Audit Committee attendance and separate discussions
The Audit Committee typically invites the non-executive Chair, Group Chief Executive Officer, Group Finance Director, Group Financial Controller, 
the Group’s Director of Tax & Strategic Finance, the Group’s Director of Risk and Assurance and senior representatives of the external audit firm 
to attend its meetings, although it reserves the right to request any of these individuals to withdraw from any meeting.
Significant risks considered by the Audit Committee
The table below summarises the significant risks considered by the Audit Committee, including significant judgments and estimates:
Significant risks considered by the Audit Committee
How the risk was addressed by the Audit Committee
Legal claim and warranty provisions
Provisions are held where management considers there is an obligation, 
payment is probable and the amount payable can be reliably estimated.
Provisions held by the Group include but are not limited to those held 
against legal claims and contractual matters and product warranties.
There is a risk that other provisions overstate or understate the 
associated liability.
The Audit Committee considered the basis upon which management 
had made its accounting judgments to determine the level of legal claim 
and warranty provisions. The Audit Committee carefully considers the 
assumptions applied and provides appropriate challenge including an 
assessment of the related sensitivities (See Note 24). These were further 
discussed with the External Auditor.
The Audit Committee believes there are no further reportable issues 
arising from these significant areas.
Tax provisioning for uncertain risk exposures, which was a significant risk in the Annual Report & Accounts 2023, is no longer considered a 
significant risk as the reorganisation of the Group’s legal entities’ structure in 2023 had reduced the reasonable range of estimated outcomes.
Other judgments and estimates
The Audit Committee considered other areas of focus where judgments and estimates have a significant effect on the amounts recognised in the 
2024 Financial Statements. These areas of focus and how they were addressed by the Audit Committee are described below:
Other focus areas considered by the Audit Committee
How these were addressed by the Audit Committee
Other key judgments and estimates
These include, but are not limited to, judgments and estimates in areas 
not covered by significant risks such as going concern and viability, 
goodwill impairment assessment, retirement benefits, leases and 
income taxes (including uncertain risk exposures) and inventory net 
realisable value.
We continue to progress strategic options for our Aerostructures 
business including the potential divestment of the business. At 31 
December 2024, judgment is required to determine whether the 
business is classified as held for sale in accordance with IFRS 5.
The Audit Committee reviewed the accounting presentation and 
judgmental issues paper, including a funding and liquidity report, for the 
related reporting period from the Group Financial Controller. In addition, 
the Audit Committee received a tax memorandum paper for the related 
reporting period from the Group’s Head of Tax & Strategic Finance.
In its review of these presentation papers, the Audit Committee 
challenged management on the critical accounting judgments, 
and the key sources of estimation and uncertainty that were taken 
in the preparation of the Financial Statements, and concluded that they 
were appropriate.
The Audit Committee reviewed the critical accounting judgment 
that Aerostructures does not meet the criteria for held for sale at 
31 December 2024 and concluded that, in line with the assessment 
taken in the prior year, this continues to be appropriate treatment up 
to and including the assessment date of 31 December 2024. 
The Audit Committee believes there are no further reportable issues 
arising from these other key judgments and estimates.

AUDIT COMMITTEE REPORT CONTINUED
Presentation of results
The Board has a policy to separately disclose 
items it considers are outside the normal 
course of management oversight and control 
on a day-to-day basis and are not reflective of 
in-year trading performance. Indicative criteria 
such as the period to which the item relates 
and external driven factors that are outside of 
the control of the Group in combination with 
the magnitude and consistency of application 
are also considered. 
The Audit Committee assessed the presentation 
to ensure a fair and balanced treatment of what 
is and is not included as an adjusting item, 
considered related guidance issued by the 
Financial Reporting Council (“FRC”) and the 
European Securities and Markets Authority 
(“ESMA”), and the need to ensure any 
alternative performance measures are 
presented with equal prominence to reported 
figures and on a consistent basis year-on-year.
The Audit Committee discussed the 
presentation of adjusted items with the External 
Auditor, and concurs with management’s view 
that the presentation of items excluded from 
and included in adjusted results, combined with 
wider disclosures throughout the Annual Report, 
provides useful information to aid the 
understanding of the performance of the Group.
External audit 
Independence of the External Auditor and 
policy on the provision of non-audit services 
The Audit Committee is responsible for 
reviewing and monitoring the External Auditor’s 
independence. To fulfil this responsibility, the 
Audit Committee reviewed an annual letter of 
independence issued by the External Auditor 
confirming their independence and compliance 
with the FRC Ethical Standard and detailing 
safeguards to maintain independence, including 
limiting the scope and value of non-audit 
services provided by the External Auditor.
The Company maintains a Policy for the 
provision of non-audit services by the External 
Auditor (the “Policy”), which is aimed at 
mitigating any risks threatening, or appearing to 
threaten, the External Auditor’s independence 
and objectivity arising through the provision of 
non-audit services. The Policy, which is in line 
with recommendations set out in the FRC’s 
Guidance on Audit Committees (2016), was 
updated in 2024, to align it with the 
requirements of the Ethical Standard 2024.
The Policy differentiates between:
•	 permitted non-audit services, for which 
the Audit Committee has pre-approved the 
use of the External Auditor subject to the 
below limits:
Value
Approval required prior 
to engagement of the 
External Auditor
up to £25,000 
Group Finance Director
£25,000 – £50,000
Chair of the Group Audit 
Committee (or delegate)
£50,000 and above
Group Audit Committee
and
•	 prohibited non-audit services.
When reviewing requests for permitted non-
audit services, the Audit Committee assesses:
•	 whether provision of such services impairs 
the External Auditor’s independence or 
objectivity and any safeguards in place to 
eliminate or reduce such threats;
•	 the nature of non-audit services;
•	 whether the skills and experience make the 
External Auditor the most suitable supplier 
of the non-audit service;
•	 the fee to be incurred for non-audit services, 
both for individual non-audit services and in 
aggregate, related to the Group audit fee; and
•	 the criteria which govern the compensation 
of the individuals performing the audit.
In addition, the Ethical Standard requires an 
assessment of whether it is probable that an 
objective, reasonable and informed third party 
would conclude independence is not 
compromised. The approval of the Audit 
Committee must be obtained before the 
External Auditor is engaged to provide any 
non-audit services and these services are 
limited to activities which feature on the 
approved Permitted Non-Audit Services list. 
The total fees for non-audit services shall be 
limited to no more than 70% of the average of 
the statutory audit fee for the Company, of its 
controlled undertakings and of the consolidated 
Financial Statements paid to the External Auditor 
in the last three consecutive financial years.
In 2024, the permitted services undertaken 
by KPMG LLP are set out in the table below. 
The Audit Committee considered that it was 
beneficial for the Company to retain KPMG LLP 
for a small amount of permitted non-audit work 
and audit-related services, because of the firm’s 
knowledge of the Group and our requirements 
that the Interim audit be performed by the 
External Auditor. The Audit Committee 
continues to closely monitor the nature 
and level of such permitted non-audit work.

Policy on tendering 
In order to maintain auditor independence 
and comply with FRC, EU guidance and the 
provisions of the CMA Order 2014 on audit 
tendering, the Group undertook a formal tender 
of its external audit during the first half of 2016, 
led by the Audit Committee. The appointment 
of KPMG LLP as the Group External Auditor for 
the financial year commencing 1 January 2017 
received approval by shareholders at the Annual 
General Meeting held in April 2017. 
The Audit Committee reviews annually whether 
it is appropriate to put the external audit out to 
tender. During the second half of 2024 the 
Board, with the recommendation of the Audit 
Committee, agreed that the Company would 
conduct a competitive tender of the 2027 
year-end audit during 2025. In the second half 
of 2024, the Audit Committee selected 
participants to invite based on assessment of 
global reach with scale, interest and resources 
to conduct a complex international audit. At this 
stage of the process, due consideration was 
given to mid-tier firms as required by the FRC.
The Audit Committee fully evaluates auditor 
performance and independence annually but 
does not favour mandatory five-year rotation.
Assessment of external audit 
quality and effectiveness
The Audit Committee reviewed the effectiveness 
of the External Auditor and the external audit 
process, including an assessment of the quality 
of the audit, at its September 2024 meeting. 
In 2024, the assessment of the effectiveness 
of the external audit process was again 
performed by assessing a range of key areas 
through a formal questionnaire that was 
individually distributed to all the members of 
the Audit Committee and all other executive 
and non-executive Directors. The questionnaire 
considered the following aspects:
•	 calibre of the external audit team and the 
audit partner;
•	 the robustness of the external audit 
process and degree of challenge to 
matters of significant audit risk and areas 
of management subjectivity;
•	 the degree of professional scepticism 
applied by the External Auditor;
•	 quality of the audit and audit planning 
approach;
•	 role of the management;
•	 communication and formal reporting by the 
External Auditor to the Audit Committee;
•	 the External Auditor’s support of the work 
of the Audit Committee;
•	 insights and adding value;
•	 audit fees; and
•	 independence and objectivity.
Senior management received answers 
and comments from all questionnaires and 
consolidated them into a report. The Audit 
Committee used this report to facilitate a 
debate at its September 2024 meeting and 
to assist in assessing the level of external 
audit effectiveness.
SENIOR PLC ANNUAL REPORT AND ACCOUNTS 2024

GOVERNANCE

Examples of the Auditor’s professional scepticism 
and challenge of management’s assumptions, as 
noted by the Committee, include:
•	 Held for sale accounting – the External 
Auditor challenged whether the potential 
divestment of Aerostructures business met 
the threshold of highly probable, including 
whether the expectation that it would be 
completed within 12 months was fully met as 
at 31st December 2024; and concurred with 
the judgment taken by the Board.
•	 Valuation of customer claims provision – 
the External Auditor challenged the 
assumptions and found the provisions for 
customer claims continued to be balanced 
and the provision recorded reflected the 
inherent uncertainty.
•	 Valuation of defined benefit pension 
liability – performing benchmarking 
of management’s assumptions for the 
valuation of defined benefit obligations 
by comparing assumptions using their 
independent expectations. 
Feedback about the effectiveness of the 
external audit process from the local 
management teams was also considered by 
the Audit Committee. The Audit Committee 
concluded that the External Auditor had 
challenged the thinking of the Company and of 
the Audit Committee on a number of significant 
issues and had maintained its independence.
Following completion of the assessment 
process outlined above, the Audit Committee 
concluded that it was satisfied with the 
effectiveness of the External Auditor; as a 
consequence, the Audit Committee has 
recommended to the Board that KPMG LLP 
be re-appointed as Auditor for 2025. 
Specific areas referred to the 
External Auditor
In 2024, the Audit Committee has not asked 
the Auditor to explicitly review any specific 
areas because the significant risks and other 
focus areas considered by the Auditor were 
aligned with the significant risks considered 
by the Audit Committee. The Audit Committee 
was satisfied with the results of the Auditor’s 
results and findings.
Internal control and risk management
The Audit Committee is responsible for 
reviewing the Company’s internal financial 
controls and risk management systems. The 
Group Director of Risk and Assurance, supported 
by the Internal Audit Manager, provided regular 
reports to the Committee on the findings of the 
internal audits performed at the Group operating 
businesses. The reports, covering a range of 
financial and non-financial controls, evaluated the 
operation of controls and detailed specific areas 
for improvements, where applicable.
The Chair and non-executive Directors are 
actively encouraged to visit the Group’s 
operating businesses unaccompanied by 
executive Directors. Such visits enable the 
Directors to meet the local management teams 
and employees and also undertake site tours 
to review matters including production methods, 
health and safety and the status of internal audit 
findings. These visits are viewed by the Audit 
Committee as making a positive contribution 
to the internal control framework.
There have been no substantive changes to the 
Group’s Enterprise Risk Management process 
during 2024; the Executive Committee 
considers emerging risks alongside the principal 
risks. Throughout the year, the Audit Committee 
received comprehensive reports covering risk, 
assurance and compliance activities. 
Supplementary functional risk assessments 
covering sustainability-related risks and 
opportunities, fraud and facilitation of tax 
evasion were completed in 2024. The outcomes 
of the risk assessments were reported to the 
Board, as part of the annual review of the 
Group’s risk management processes.
In preparation for the enhanced reporting 
obligations under provision 29 of the UK 
Corporate Governance Code 2024, the Audit 
Committee received updates on the steps 
taken by the Company to review its existing 
internal control environments. The Committee 
will continue to provide effective oversight 
to the Group’s internal control system to 
ensure compliance with the forthcoming 
regulatory change.
Internal audit
The Audit Committee is responsible for 
monitoring and reviewing the effectiveness of 
the Company’s internal audit function, which is 
headed by the Director of Risk and Assurance, 
with the support of the Internal Audit Manager. 
In 2023, the Committee approved the 
Senior plc Internal Audit Charter, a formal 
document defining the responsibilities and 
authority of the internal audit function at Senior. 
During its February 2024 meeting, the 
Committee reviewed the 2024 internal audit 
plan, detailing scheduled assurance and risk 
management activities. Regular progress r
eports were provided to Audit Committee 
throughout the year.
As part of assessing the effectiveness of the 
internal audit function, the Audit Committee 
held two private sessions with the Director of 
Risk and Assurance without the executive 
Directors being present. The Committee 
remained satisfied that the internal audit plan 
was well aligned to the principal risks of the 
Company and was effective in evaluating the 
operation of internal controls. 
During 2024, the Audit Committee reviewed 
the results of a comprehensive internal 
quality assessment completed by the 
Company of the internal audit function. 
The assessment evaluated the function 
against the 2017 International Standards 
for the Professional Practice of Internal 
Auditing and Code of Ethics as maintained 
by the Institute of Internal Auditors.
During its meeting on 31 July 2024 and 
25 February 2025, the Audit Committee 
concluded that the Internal Audit function had 
operated with adequate resources and access 
to personnel, data and documents necessary 
to effectively conduct its Internal Audit plan.
Conclusion
As a result of its work during the year, the Audit 
Committee has concluded that it has acted fully 
in accordance with its Terms of Reference. At its 
meeting held on 25 February 2025, the Audit 
Committee considered each section of the draft 
Annual Report & Accounts 2024, and the 
document as a whole, as proposed by the 
Company; it reached a conclusion and advised 
the Board that it considered the draft Annual 
Report & Accounts 2024 to be fair, balanced and 
understandable and that it provided the 
information necessary for shareholders to 
assess the Group’s position and performance, 
Business Model and strategy. As the Chair of 
the Audit Committee, I will continue, where 
appropriate, to be available to engage with 
shareholders on the scope of the external audit 
and other significant matters related to the Audit 
Committee’s areas of responsibility and I will be 
available at the 2025 AGM to answer any 
shareholders’ questions about the work of the 
Audit Committee.

INFORMATION

Dear Shareholder,
I am pleased to present the Report of the 
Remuneration Committee for the financial year 
ended 31 December 2024. This statement sets 
out the work of the Committee during the year 
and provides the context for the decisions taken. 
The Report will be subject to an advisory vote at 
our forthcoming AGM.
The link between strategy 
and remuneration
Senior’s Purpose is “We help engineer the 
transition to a sustainable world for the benefit 
of all our stakeholders” and its Vision is to be 
a trusted and collaborative high value-added 
engineering and manufacturing company 
producing sustainable growth in operating 
profit, free cash flow and shareholder value. 
This is supported by a number of key strategic 
priorities, as explained in detail in the 
Strategic Report on pages 34 to 35.
Our approach to executive remuneration 
supports this Vision, with our bonus plans 
incentivising earnings growth, free cash flow 
and sustainability, and our long-term plans 
rewarding the creation of shareholder value, 
earnings growth and return on capital. We 
regularly consider the alignment of our 
performance metrics with the business strategy 
and over time have evolved our approach to 
reflect changes in strategic focus and the views 
of shareholders. As a reminder, for 2024 we 
introduced two non-financial measures into the 
annual bonus to link incentives more closely 
with Senior’s sector-leading approach to 
sustainability and wider ESG matters.
The incentive framework is set out in our 
Remuneration Policy, the renewal of which was 
supported by over 92% of the shareholder vote 
at last year’s AGM, following a shareholder 
engagement exercise which helped to shape 
the final proposals. The Committee was also 
pleased with the vote of over 98% in favour of 
the Directors’ Remuneration Report for 2023 
and over 93% in favour of the new LTIP plan 
rules. I would like to thank shareholders for 
their input and continued support for the 
Committee’s approach. A summary of the 
Remuneration Policy is set out on pages 99 
to 101 of this report.
Senior’s performance during 2024
Senior has delivered 2024 results with trading 
in line with revised expectations and strong 
cash performance, notwithstanding the 
well-documented situation at Boeing. 
We responded dynamcially, supporting our 
customers and controlling our costs, limiting 
the impact on Aerospace profitability. Our 
Aerospace revenue and profits have grown.
In Flexonics, we outperformed softer markets 
and delivered double-digit margins, albeit 
revenues and profits were slightly lower 
as anticipated.
In 2024, Senior has continued to deliver on 
its strategy by investing in markets where we 
believe there is a significant growth potential 
and where the Group’s skills and knowledge 
can be exploited, such as aerospace highly 
engineered standard parts/components.
Executive Directors’ remuneration 
for 2024
The executive Directors were eligible for an 
annual bonus of up to 150% of basic salary, 
payable subject to the achievement of stretching 
targets linked to key performance metrics.
A total of 80% of the bonus was based on 
adjusted EPS and free cash flow, maintaining 
the ratio between these two financial metrics 
at 60% and 40% respectively. Reflecting the 
headwinds described above, performance did 
not reach the lower threshold of the stretching 
ranges set at the start of the year, and therefore 
no bonus was payable for these elements.
The remaining 20% of the bonus was based on 
two key non-financial measures introduced into 
the bonus for 2024 to link our incentives more 
closely to sustainability and wider ESG matters. 
As described in the Sustainability Report, we 
achieved a significant reduction in our Scope 1 
and 2 emissions during 2024, which means the 
2024 performance is already better than our 
stated objective to deliver a 30% reduction in 
such emissions by 2025. Our employee 
engagement score increased year-on-year, 
reflecting our focus on talent, development 
and creating an environment where employees 
feel motivated and engaged. For both of these 
metrics, performance was above the upper 
end of the stretching range set, resulting in full 
pay-out. Details of the targets are set out on 
page 104.

REMUNERATION COMMITTEE REPORT 
CHAIR’S ANNUAL STATEMENT

Overall, bonuses were therefore achieved 
at a level of 20% of the maximum, leading 
to an outcome of 30% of basic salary for 
both Directors. In reviewing this outcome, 
the Remuneration Committee considered the 
wider performance of the business during the 
year and the contributions of the management 
team to the successful implementation of 
the strategy for the year. The Committee 
concluded that the outcome was an appropriate 
and fair outcome for all stakeholders.
The 2022 LTIP award was based on 
performance over the three years to 
31 December 2024, using three equally 
weighted performance metrics: Return on 
Capital Employed (“ROCE”), adjusted EPS 
and relative Total Shareholder Return (“TSR”). 
Again, reflecting external headwinds during 
the period, ROCE and adjusted EPS outturns 
were below the relevant minimum thresholds. 
However, TSR performance was above 
median resulting in a vesting of 36% of 
maximum for that element. Overall, the award 
will vest at 12% of maximum and is subject 
to a two-year post-vesting holding period. 
Further details are set out on page 105.
Executive Director succession in 2025
As disclosed during 2024, Bindi Foyle is due to 
retire as Group Finance Director shortly after the 
2025 AGM after 19 years with the Group. Bindi 
will be succeeded by Alpna Amar who will join 
the Senior plc Board in April 2025 and will 
succeed Bindi as Group Chief Financial Officer in 
May 2025. The Committee has determined the 
remuneration arrangements which will apply in 
line with our Remuneration Policy. 
On appointment, Alpna’s salary will be set at 
£400,000. Alpna will be eligible for an annual 
bonus of 150% of basic salary (pro-rated for 
2025 to reflect the portion of the year worked) 
and a 2025 LTIP award of 175% of basic salary. 
To compensate Alpna for the forfeiture of equity 
awards from her previous employment, the 
Committee has agreed to grant replacement 
awards following appointment which would 
remain subject to performance conditions 
where appropriate and would mirror the value 
and the vesting/release schedule of the forfeited 
share awards, in line with the recruitment 
provisions in our Remuneration Policy. Full 
details of these awards will be disclosed at the 
time of grant and in next year’s report.
Implementation of the Policy for 2025
Basic salaries for David Squires and Bindi Foyle 
will increase by 2.4% and 2.1% respectively, 
with effect from 1 January 2025. This is below 
the average increase of 4.25% for employees 
across our operations. Pension contributions for 
the Directors will remain at 15% of basic salary, 
aligned with the contribution rate available to the 
majority of the UK workforce.
In line with the Policy, the executive Directors 
will have the opportunity to earn up to 150% 
of basic salary as an annual bonus for 2025 
(subject to appropriate pro-rating in respect 
of the Group Chief Financial Officer). The 
performance measures will remain unchanged 
from 2024, reflecting the refinements made to 
our framework in last year’s Policy review. A total 
of 80% of the bonus will remain subject to 
challenging financial targets linked to adjusted 
EPS and free cash flow. The remaining 20% will 
be based on two equally weighted quantitative 
strategic non-financial measures: absolute 
reductions in Scope 1 and Scope 2 emissions 
and progress in Senior’s employee engagement 
score. The specific targets are considered 
commercially confidential at this stage but will be 
published in full in next year’s report. Any bonus 
payment will be subject to the appropriate 
deferral arrangements and the standard malus 
and clawback provisions set out in our Policy.
In 2025, David Squires and Alpna Amar will be 
granted LTIP awards at a level of 200% and 
175% of basic salary, respectively, in view of 
her retirement, Bindi Foyle will not participate 
in the 2025 LTIP. The headline performance 
metrics will be unchanged, with the retention 
of the existing mix of ROCE, relative TSR and 
adjusted EPS, each with a one-third weighting. 
These metrics provide for a combined focus 
on absolute financial performance, returns to 
shareholders and efficient use of capital, all of 
which are critically important to the business 
and to investors. The specific targets for the 
2025 LTIP award are considered suitably 
challenging over the performance period, 
which runs to the end of the 2027 financial 
year, and recognise our long-standing belief 
that maximum vesting should require material 
outperformance. The adjusted EPS target 
range has been set at 13.40p to 19.42p with 
the ROCE range maintained at 13.5% to 17.0%, 
requiring outperformance of our stated 
long-term strategic ambition.
The TSR element will be based on Senior’s 
performance relative to the FTSE 350 
(excluding companies in the Financial Services, 
Oil, Gas & Coal, Mining and Real Estate 
sectors). For maximum vesting, upper quartile 
performance will be required, in line with 
conventional market practice for TSR 
performance conditions. Further details 
on the targets are set out on page 109. 
Any awards which vest will be subject to 
the usual Committee assessment of overall 
performance over the LTIP period as well 
as a two-year post-vesting holding period. 
Malus and clawback provisions will apply.
Consultation with stakeholders 
during the year
Consultation with shareholders
As reported last year, I held a number of 
conversations with major shareholders in 
respect of the renewal of the Directors’ 
Remuneration Policy and of the LTIP plan 
rules, and the feedback we received helped to 
shape the final proposals. Further shareholder 
engagement on remuneration matters will take 
place as appropriate over the coming year.
Consultation with employees regarding 
executive remuneration
During the year, I reviewed executive 
remuneration with employee representatives 
from the UK operating businesses. In addition, 
Mary Waldner, as the designated non-executive 
Director with responsibility for employee 
engagement, met with employees across the 
wider Group and discussed a variety of subjects, 
including remuneration.
Wider workforce remuneration 
The Committee continues to pay close attention 
to remuneration policies and practices across 
the wider workforce, and takes these into 
account when agreeing the shape and level 
of the executive Directors’ remuneration. 
Participation in the LTIP extends to around 
50 senior executives within the business, 
all of whom are subject to the same 
performance conditions as the executive 
Directors. The new ESG performance measures 
which were introduced into the Directors’ 
annual bonus plan for 2024 were also rolled out 
to all those business leaders who participate in 
the Group’s senior manager bonus plan.
Equity awards in the form of restricted shares 
are granted to select individuals who are 
considered to have significant potential or who 
are key contributors. All-employee share plan 
arrangements are offered to employees in the 
UK, US and continental Europe in the interests 
of encouraging wider levels of share ownership 
across the business. A new Sharesave contract 
will be launched later in 2025.
AGM
At the AGM on 25 April 2025, shareholders will 
be asked to vote on the Annual Remuneration 
Report. I trust that the decisions the Committee 
has taken in respect of 2024 will have your 
support. If you have any questions on this 
Report or on remuneration matters more 
generally, I can be contacted via the Group 
Company Secretary.

members of the Committee, Barbara Jeremiah and Ian King, to hold six additional 
meetings to confirm the granting and vesting of share awards.
(2)	 Zoe Clements was appointed to the Board on 1 September 2024 and attended all three 
of the meetings that were held in 2024 following her appointment.
Other attendees at Remuneration Committee meetings
The Group Chief Executive Officer and Group HR Director attend 
meetings by invitation and the Group Company Secretary acts as 
secretary to the Committee but no executive Director or other employee 
is present during discussions relating to his or her own remuneration.
Advisers
Before recommending proposals for Board approval, the Remuneration 
Committee may seek advice from external remuneration consultants to 
ensure that it is fully aware of comparative external remuneration practice 
as well as shareholder, legislative and regulatory developments. The 
Committee also considers publicly available sources of information 
relating to executive remuneration.
The Committee does not have a formal policy of subjecting its 
remuneration consultants to a regular fixed-term rotation, although the 
Committee remains cognisant of the need to seek objective advice and 
good value whilst also benefiting from the consultants’ knowledge of the 
Company. During the year, the Committee appointed Alvarez & Marsal as 
its remuneration adviser following a competitive tender process.
All advisers to the Remuneration Committee are appointed and instructed 
by the Committee. During the year, the Committee was advised by Korn 
Ferry and Alvarez & Marsal in relation to remuneration advice (including in 
relation to the appointment of Alpna Amar and other executives) and 
benchmarking, LTIP performance monitoring and the provision of LTIP 
advice. During 2024, the Company incurred fees of £25,308 from Korn 
Ferry, £16,950 from Alvarez & Marsal and £5,401 from FIT Remuneration 
Consultants, and these costs were based on a combination of hourly rates 
and fixed fees for specific items of work. Korn Ferry, Alvarez & Marsal, 
and FIT Remuneration Consultants are members of the Remuneration 
Consultants Group and adhere to its Code in relation to executive 
remuneration consulting in the UK. The remuneration consultants that 
provided services during the year have no other connections with the 
Company or its Directors. The Committee is satisfied that the advice it 
has received during 2024 has been objective and independent.

Factors considered in applying the Policy
The Committee is comfortable that the Policy and its implementation are fully consistent with the factors set out in the UK Corporate Governance 
Code as applied for 2024 (set out below):
•	 Clarity – The Policy and the way it is implemented is clearly disclosed in this policy section of the Directors’ Remuneration Report, with full 
transparency of all elements of Directors’ remuneration.
•	 Simplicity – The Policy is simple and straightforward, based on a mix of fixed and variable pay. The annual bonus and LTIP include performance 
conditions which are aligned with Senior’s business strategy.
•	 Risk – The Committee believes that the performance targets in place for the incentive schemes provide appropriate rewards for stretching levels 
of performance without driving behaviour which is inconsistent with the Company’s risk profile and Values. Potential reward is aligned with market 
levels of peer companies and the reputational risk from a perception of “excessive” pay-outs is limited by the maximum award levels set out in the 
Policy and the Committee’s discretion to adjust formulaic remuneration outcomes.
•	 Predictability – The Policy includes full details of the individual limits in place for the incentive schemes. Any discretion exercised by the Committee 
in implementing the Policy will be fully disclosed.
•	 Proportionality – The link between the delivery of strategy, long-term performance, shareholder return and the remuneration of the executive 
Directors is set out in the Remuneration Report.
•	 Alignment to culture – The approach to Directors’ remuneration is consistent with the Group’s culture and Values.

(1)	 Taxable benefits for executive Directors include the provision of a fully expensed company car or car allowance and private medical insurance. Taxable benefits for non-executive 
Directors are travel expenses.
(2)	 Under the Remuneration Policy, the deferred bonus would ordinarily be paid two-thirds in cash and one-third in Senior shares.
(3)	 Part of the performance conditions attached to David Squires’ and Bindi Foyle’s 2022 LTIP Awards were achieved, and therefore 12.03% of this award will vest in March 2025. Further 
details on the performance conditions can be found on page 98. The estimated value of shares to vest in the next period includes an amount for the dividend equivalent shares and was 
calculated using the average of daily closing market value of the shares over the last three months of 2024 of 145.0p. 16.6% of the value of the LTIP awards is attributable to share price 
appreciation, as the share price has increased from £1.21 at the time of grant.
(4)	 Joe Vorih and Zoe Clements were appointed to the Board on 1 January 2024 and 1 September 2024 respectively, and their 2024 fees are the amounts paid from those respective 
dates. From 22 April 2023, Barbara Jeremiah became Chair of the Remuneration Committee and the Senior Independent Director, and Mary Waldner became Chair of the Audit 
Committee and the Director with responsibility for employee engagement; and their respective fees were adjusted accordingly. Celia Baxter and Giles Kerr both retired from the 
Board in April 2023 and their 2023 fees are the amounts paid until their respective retirements.
(5)	 The aggregate amount of remuneration paid to or receivable by Directors in respect of qualifying services as per paragraph 9 of SI 2008/40 Schedule 5 was £2,139,407 
(2023 – £2,752,795). Included within this was £1,400,692 (2023: £nil) paid in respect of long-term incentive schemes, £155,250 (2023: £148,050) paid as company contributions 
to pension schemes on behalf of two (2023: two) of the directors, and £nil (2023: £nil) in respect of gains on the exercise of share options granted.
Performance against performance targets for annual bonus (audited information)
Bonuses are earned by reference to the financial year and paid in March following the end of the financial year. As outlined in the 2023 Remuneration 
Report, the bonuses accruing to the executive Directors in respect of 2024 have been determined by adjusted EPS, free cash flow, CO2 emissions 
reductions, and Employee engagement performances as set out in the table below.

In reviewing the bonus outcome, the Remuneration Committee considered the wider performance of the business during the year and the 
contributions of the management team to the successful implementation of the strategy for the year. The Committee concluded that the outcome 
was an appropriate and fair outcome for all stakeholders.
Total pension entitlements (audited information)
The 2024 single figure remuneration for pension benefits for David Squires and Bindi Foyle consisted of a cash allowance of £92,250 (2023 – £88,050) 
and £63,000 (2023 – £60,000) respectively, this being 15% of the respective base salaries, in line with the Remuneration Policy.
Payments for loss of office (audited information)
There were no payments made in the year for loss of office.
Fees received for outside appointments
The Board supports executive Directors taking up appointments outside the Company to broaden their knowledge and experience. Each executive 
Director is permitted to accept one non-executive appointment from which they may retain any fee. Any external appointment must not conflict with 
a Director’s commitments to Senior plc.
David Squires does not hold any outside appointments for which he is remunerated. Bindi Foyle was appointed to the Board of Avon Technologies plc 
(“Avon”) as a non-executive director with effect from 1 May 2020 and retained fees of £67,298 for the year ending 31 December 2024 (£60,675 for 
the year ended 31 December 2023). Prior to her taking up this appointment, the Nominations Committee considered the time commitment required 
for this role and was supportive of her taking up that appointment, and of her subsequent appointment as Avon’s Senior Independent Director from 
April 2024.

The Company complies with the dilution guidelines contained within The Investment Association Principles of Executive Remuneration. 
At 31 December 2024, awards outstanding and shares issued in the previous 10 years under the Senior plc 2005 Long-Term Incentive Plan (the 2005 
LTIP), the Senior plc 2014 Long-Term Incentive Plan (the 2014 LTIP), the Senior plc 2024 Long-Term Incentive Plan (the 2024 LTIP), and the 2006 
Savings-Related Share Option Plan (the Sharesave Plan) amounted to 3.24% of the issued ordinary share capital of the Company. At 31 December 
2024, awards outstanding and shares issued in the previous 10 years under executive (discretionary) plans (the 2005 LTIP, 2014 LTIP and 2024 LTIP) 
amounted to 4.98% of the issued ordinary share capital of the Company.
During 2024, all share awards were satisfied using market-purchased shares. The Remuneration Committee monitors the flow rates of the Company’s 
share plans, in particular before new share awards are made, to ensure the flow rates remain within the Investment Association dilution guidelines.

Statement of Directors’ shareholding and share interests (audited information)
The Remuneration Committee encourages Directors to own shares in the Company and, in support of this policy, it expects executive Directors to 
retain at least 50% of the shares that vest under the LTIP awards and the deferred share element of the bonus, after allowing for tax liabilities, until a 
shareholding equivalent in value to 200% of base salary is built up. Included within the Directors’ holdings are 325,000 shares and 38,788 shares that 
David Squires and Bindi Foyle purchased respectively.
The table below shows how each Director complies with this requirement. Shares are valued using the Company’s closing share price on 
31 December 2024 of 159.6p (31 December 2023 – 177.6p). No options under the Sharesave Plan were exercised by the executive Directors 
during the year.

GOVERNANCE

Relationship between executive Director and employee pay
The Remuneration Policy for the executive Directors is designed taking into account the policy for employees across the Group as a whole. There are 
some differences in the structure of the Remuneration Policy for the executive Directors and other senior employees, which the Remuneration 
Committee believes are necessary to reflect the different levels of responsibility of employees across the Company and reflect different market norms 
for different roles. The key differences in remuneration policy between the executive Directors and employees across the Group are the increased 
emphasis on performance-related pay and the inclusion of a share-based long-term incentive plan for executive Directors.
The majority of senior managers are eligible to participate in annual bonus arrangements with challenging targets tied to the performance of their 
operating business, Division and the Group’s performance. 
Long-term incentives are provided to the most senior executives and those anticipated as having the greatest potential to influence performance levels 
within the Company. A lower aggregate incentive quantum operates below the senior executive level, with levels driven by the impact of the role and 
market comparatives.
Awards under the Restricted Share Award Plan, a deferred share award plan without performance conditions, are a retention tool and are made to 
selected individuals who do not typically benefit from other long-term incentives but are considered to have significant potential or are key contributors.
In order to encourage wider employee share ownership, the Company operates a Sharesave Plan in which employees in the UK, North America and 
continental Europe, including executive Directors, may participate.
The pension contributions of the executive Directors (15% of base salary) aligns with the pension contribution available to the majority of the UK workforce.
How employees’ pay is taken into account when setting executive Director remuneration
The Committee also reviews the salaries of senior corporate, divisional and operational managers and therefore is fully cognisant of pay levels in the 
Group when determining the pay of the executive Directors.
In addition, the Committee’s policy is that salary increases for the executive Directors and senior executives should not normally be greater than the 
general level of increases awarded to other senior managers in Europe and North America, other than when an executive changes role or when it is 
necessary in order to ensure levels of remuneration remain market competitive.
We continue to be vigilant regarding rates of pay and the cost of living, ensuring we are paying people fairly for the work they do, and benchmarking 
pay rates in local markets, making adjustments if appropriate and focusing higher relative salary increases on operations employees.
As laid out in the Remuneration Committee Chair’s Annual Statement, the Company consulted with UK employee representatives in 2024 regarding 
executive Director remuneration. 
Percentage change in remuneration of Directors
The table below shows how the percentage changes in Directors’ salary, benefits and bonus between 2020 and 2021, 2021 and 2022, 2022 and 
2023, and between 2023 and 2024 compare with the percentage change in the average of each of those components of pay for Senior plc 
employees. Employees who joined or left in either year have been excluded to prevent distortion.

(1)	 The Salary percentage change figure also includes any merit increases awarded to Directors and employees. The percentage change of salary percentage change figures for the 2021 
and 2020 comparison are calculated using the 2020 salaries before the voluntary reduction in salaries and fees for the Directors and some Senior plc employees during the pandemic
(2)	 David Squires’ percentage change in Taxable benefits and allowances reflects the increase in 2023 of the annual premium of his private health insurance which amounted to £587. 
Bindi Foyle’s percentage change in Taxable benefits and allowances in 2023 mainly reflects the transition from having a car allowance to having a company car during 2022.

2024 REMUNERATION REPORT: ANNUAL REPORT ON REMUNERATION CONTINUED
CEO pay ratio narrative
The CEO pay ratio is calculated using Option B, by taking the gender pay gap data (based on Senior’s largest UK employer, Senior UK Limited) and 
adding the data for Senior’s two additional UK employing entities. For the purpose of making a valid comparison, leavers were excluded. Using the 
same principles as the gender pay data, the best equivalents were identified, namely: the 25th, 50th and 75th percentile. The full-time equivalent 
pay and benefits figures for the year ending December 2024 were calculated, and then reviewed to ensure that the selected best equivalents were 
reasonably representative. The underlying salary, bonus and benefits showed a reduction in the CEO pay ratio from 2023. We believe the reduction 
compared to prior years was mainly due to the increase in bonuses for employees compared to a reduction in bonus for the CEO during 2024. 
The CEO pay ratio includes the vesting of 2022 LTIPs at 12.03% of the total potential.

(1)	 Method B was selected as the most appropriate basis for selecting the 25th percentile, median and 75th percentile pay ratios because the gender pay gap data was more readily available.
(2)	 The pay ratios in 2020 had been impacted by the pandemic leading to significant numbers of employees being on furlough and/or made redundant, as well as reduced total remuneration 
for the CEO.

Salaries and fees for 2025
We continue to be vigilant regarding rates of pay and the cost of living, ensuring we are paying people fairly for the work they do, and benchmarking 
pay rates in local markets, making adjustments if appropriate and focussing higher relative salary increases on operations employees. When 
determining the 2025 basic salaries of the Group Chief Executive Officer and Group Finance Director, which were increased by 2.4% and 2.1% 
respectively, the Committee was cognisant of the increases applied to the wider workforce, which were typically 4.25% or higher, depending upon 
skills and geographic location. Alpna Amar’s salary on her appointment as the new Group Chief Financial Officer will be £400,000 per annum.
Although determined by the Board, rather than the Remuneration Committee, the 2025 base fee for the non-executive Directors was increased by 
2.5% and had been determined after considering the increases applied to the wider workforce, and to those for the executive Directors.

Annual bonus for 2025
The maximum bonus opportunity remains 150% of basic salary, in line with the Policy. The KPIs remain unchanged from the prior year, namely, 
Free Cash Flow, Adjusted EPS, absolute reductions in Scope 1 and Scope 2 emissions in 2025, and improvements to Senior’s employee engagement 
survey score in 2025 compared to the survey results from 2024, highlighting the importance of a highly engaged workforce to achieving outstanding 
results. The individual weightings of the KPIs for the executive Directors for the annual bonus are set out below.

 disclosure of the 2025 targets will be in the 2025 Annual Report. Any bonus payment will be subject to the usual deferral arrangements and the 
standard malus and clawback provisions set out in our Policy.
LTIP awards for 2025
In 2025, David Squires and Alpna Amar will be granted LTIP awards at a level of 200% and 175% of basic salary, respectively. As described in the 
Chair’s statement, in view of her retirement, Bindi Foyle will not participate in the 2025 LTIP. The Remuneration Committee sets stretching targets 
which are consistent with the strategic priorities of the business, and vested awards will continue to be subject to a two-year holding period. Award 
levels will be 200% of basic salary, which is unchanged from 2024 and consistent with the Policy. This provides an appropriate level of reward potential 
for the outstanding levels of performance which are required to hit maximum vesting levels under the LTIP. As evidenced by the targets for the 2025 
award set out in the table below, stretching goals have been set which, if achieved, would represent an outstanding level of performance which the 
Committee believes should be rewarded accordingly.
Adjusted EPS, TSR and ROCE metrics will be retained as the performance measures in the LTIP and have equal weighting of 33.3%: 33.3%: 33.3%. 
The Adjusted EPS target has been set to be stretching and challenging. The target is expressed as an absolute value achieved in 2027. Following a 
review by the Remuneration Committee, TSR performance will be measured against the FTSE 350 (excluding companies in the Financial Services, 
Oil, Gas & Coal, Mining and Real Estate sectors) with maximum vesting requiring upper quartile performance. The Committee adjusted this from 
upper quintile to more closely align with standard practice for TSR-based performance conditions. The Committee has also updated and simplified the 
excluded sectors. The Company has consistently stated that its medium-term ROCE target is a minimum of 13.5% pre-tax, post IFRS 16 and this has 
not changed. The targets are set at a stretching level that takes account of market conditions and the minimum stated target.
The thresholds and maximum for 2025 are set out in the table below:

The Directors are responsible for preparing 
the Annual Report and the Group and Parent 
Company Financial Statements in accordance 
with applicable law and regulations. 
Company law requires the Directors to prepare 
Group and Parent Company Financial 
Statements for each financial year. Under that 
law they are required to prepare the Group 
Financial Statements in accordance with 
UK-adopted international accounting standards 
and applicable law and have elected to prepare 
the Parent Company Financial Statements in 
accordance with UK accounting standards 
and applicable law, including FRS 101 
Reduced Disclosure Framework. 
Under company law the 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 Group’s profit or loss for 
that period. In preparing each of the Group 
and Parent Company Financial Statements, 
the Directors are required to: 
•	 select suitable accounting policies and 
then apply them consistently; 
•	 make judgements and estimates that are 
reasonable, relevant, reliable and prudent; 
•	 for the Group Financial Statements, state 
whether they have been prepared in 
accordance with UK-adopted international 
accounting standards; 
•	 for the Parent Company Financial Statements, 
state whether applicable UK accounting 
standards have been followed, subject to any 
material departures disclosed and explained 
in the Parent Company Financial Statements; 
•	 assess the Group and Parent Company’s 
ability to continue as a going concern, 
disclosing, as applicable, matters related 
to going concern; and 
•	 use the going concern basis of accounting 
unless they either intend to liquidate the 
Group or the Parent Company or to cease 
operations, or have no realistic alternative 
but to do so. 
The Directors are responsible for keeping 
adequate accounting records that are sufficient 
to show and explain the Parent Company’s 
transactions and disclose with reasonable 
accuracy at any time the financial position of 
the Parent Company and enable them to ensure 
that its Financial Statements comply with the 
Companies Act 2006. They are 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, 
and have general responsibility for taking such 
steps as are reasonably open to them to 
safeguard the assets of the Group and to 
prevent and detect fraud and other irregularities. 
Under applicable law and regulations, the 
Directors are also responsible for preparing a 
Strategic Report, Directors’ Report, Directors’ 
Remuneration Report and Corporate 
Governance Statement that complies with 
that law and those regulations. 
The Directors are responsible for the 
maintenance and integrity of the corporate 
and financial information included on the 
Company’s website. Legislation in the UK 
governing the preparation and dissemination 
of Financial Statements may differ from 
legislation in other jurisdictions. 
In accordance with Disclosure Guidance and 
Transparency Rule (“DTR”) 4.1.16R, the Financial 
Statements will form part of the Annual Financial 
Report prepared under DTR 4.1.17R and 4.1.18R.

1. Our opinion is unmodified
We have audited the financial statements 
of Senior plc (“the Company”) for the year 
ended 31 December 2024 which comprise 
the Consolidated income statement, the 
Consolidated statement of comprehensive 
income, Consolidated balance sheet, 
Consolidated statement of changes in equity, 
Consolidated cash flow statement, Company 
balance sheet and Company statement of 
changes in equity and the related notes, 
including the accounting policies in note 2 and 35.
In our opinion:
•	 the financial statements give a true and fair 
view of the state of the Group’s and of the 
parent Company’s affairs as at 31 December 
2024 and of the Group’s profit for the year 
then ended;
•	 the Group financial statements have been 
properly prepared in accordance with UK-
adopted international accounting standards;
•	 the parent Company financial statements 
have been properly prepared in accordance 
with UK-adopted international accounting 
standards, including FRS 101 Reduced 
Disclosure Framework and as applied in 
accordance with the provisions of the 
Companies Act 2006; and
•	 the financial statements have been prepared 
in accordance with the requirements of the 
Companies Act 2006.
Basis for opinion
We conducted our audit in accordance with 
International Standards on Auditing (UK) (“ISAs 
(UK)”) and applicable law. Our responsibilities 
are described below. We believe that the audit 
evidence we have obtained is a sufficient and 
appropriate basis for our opinion. Our audit 
opinion is consistent with our report to the 
audit committee.
We were first appointed as auditor by the 
shareholders on 21 April 2017. The period of total 
uninterrupted engagement is for the eight financial 
years ended 31 December 2024. We have fulfilled 
our ethical responsibilities under, and we remain 
independent of the Group in accordance with, 
UK ethical requirements including the FRC Ethical 
Standard as applied to listed public interest 
entities. No non-audit services prohibited by that 
standard were provided.

The risk
Our response
Held for sale judgement
Refer to critical judgement accounting 
policy in note 2 on page 130 and the 
Audit Committee Report on page 93.
Subjective Judgement
The Group is actively marketing the sale of 
the Aerostructures business. Aerostructures 
is a sub section of the Groups’ Aerospace 
segment. The Group have determined that 
the potential divestment was not sufficiently 
progressed to trigger a classification of held 
for sale under IFRS 5 (being the relevant 
accounting standard), as it was not “highly 
probable” based on the facts and 
circumstances as at 31 December 2024. 
This determination involved significant 
judgement to evaluate the criteria under IFRS 
5. If the alternative judgement had been made 
there would be significant presentational and 
disclosure changes required. 
The effect of these matters is that, as part of 
our risk assessment, we determined that the 
judgement over whether Aerostructures 
should be considered as held for sale is 
highly subjective. The financial statements 
disclose the significant judgement applied by 
the Group in note 2. 
Our procedures included:
•	 Assessing the judgement: Challenged the 
directors’ accounting judgement as to whether 
or not the criteria for the sale being “highly 
probable” under IFRS 5 was met for recognising 
as held for sale based on the facts and 
circumstances as at 31 December 2024.
•	 Obtaining additional representations: 
Obtained specific representations from the 
directors over the judgement made and the 
disclosure of the facts and circumstances known 
as at 31 December 2024.
•	 Our sector expertise: Assessed the level of 
uncertainty through discussion with our own 
Deal Advisory expert in the aerospace sector to 
understand the current state of the market, 
and the factors that could effect the likelihood 
of completion within 12 months of year end.
•	 Personnel interviews: Corroborated 
judgements through discussions with Key 
Executive management and Board members.
•	 Examining correspondence: Confirmed the 
status of the sales process as at year end with 
the financial advisor.
•	 Assessing transparency: Assessed whether 
the disclosure reflects the critical accounting 
judgement that has been made, and the potential 
implication of an alternative judgement on the 
Group financial statements.
We performed the tests above rather than seeking 
to rely on any of the Group’s controls because the 
nature of the balance is such that we would expect 
to obtain audit evidence primarily through the 
detailed procedures described.
Our results
•	 We found the accounting judgement and the 
associated disclosure that the criteria under 
IFRS 5 has not been met for recognising as held 
for sale to be acceptable. 
2. Key audit matters: our assessment 
of risks of material misstatement
Key audit matters are those matters that, 
in our professional judgement, were of most 
significance in the audit of the financial 
statements and include the most significant 
assessed risks of material misstatement 
(whether or not due to fraud) identified by us, 
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. We summarise below 
the key audit matters, in decreasing order of 
audit significance, in arriving at our audit opinion 
above, together with our key audit procedures 
to address those matters and, as required for 
public interest entities, our results from those 
procedures. These matters were addressed, 
and our results are based on procedures 
undertaken, in the context of, and solely for the 
purpose of, our audit of the financial statements 
as a whole, and in forming our opinion thereon, 
and consequently are incidental to that opinion, 
and we do not provide a separate opinion on 
these matters.

Our response
Completeness and accuracy 
of warranty provisions
£11.8m included within warranty provisions 
of £19.2m (2023: £11.0m within £17.9m)
Refer to page 129 (accounting policy) and 
page 154 (financial disclosures) and the 
Audit Committee Report on page 93.
Subjective estimate
There are significant judgements and 
estimates involved in the assumptions 
underlying the warranty provision in relation 
to a disputed commercial position. Given 
the judgement required in determining this 
provisioning, we have identified this as an 
area at high risk of fraud or error.
The effect of these matters is that, as part of 
our risk assessment, we determined that the 
provision in respect of this warranty claim 
have a high degree of estimation uncertainty, 
with a potential range of reasonable outcomes 
greater than our materiality for the financial 
statements as a whole.
The financial statements (note 2) disclose 
the sensitivity estimated by the Group.
Our procedures included:
•	 Assessing methodology: Evaluated the 
methodology applied by the directors to the 
estimation to assess its reasonableness.
•	 Our sector experience: Evaluated the 
assumptions using our sector knowledge 
and inspecting commercial and customer 
correspondence.
•	 Tests of detail: Assessed the accuracy of the 
cost of replacement through testing a sample 
of cost lines to relevant source data and testing 
the number of products sold in the year.
•	 Personnel interviews: Corroborated 
judgements through discussions with 
commercial and engineering level staff.
•	 Assessing transparency: Assessed whether 
the disclosures of the effect of reasonably 
possible changes in key judgements and 
assumptions reflects the risks inherent in the 
provisions’ estimation.
We performed the tests above rather than seeking 
to rely on any of the Group’s controls because the 
nature of the balance is such that we would expect 
to obtain audit evidence primarily through the 
detailed procedures described.
Our results
•	 We found the level of provision in respect of this 
disputed commercial position to be acceptable 
(2023 result: acceptable).
Recoverability of the parent Company’s 
investment in its subsidiary
The parent Company recorded an 
investment carrying value of £259.9m 
as at 31 December 2024 (2023: £259.9m)
Refer to page 168 (accounting policy) 
and page 168 (financial disclosures).
Low risk, high value:
The carrying amount of the parent 
Company’s investment in its subsidiary 
represents 56% (2023: 52%) of its total 
assets. Its recoverability is not at a high risk 
of significant misstatement or subject to 
significant judgement. However, due to its 
materiality in the context of the parent 
Company financial statements, this is 
considered to be the area that had the 
greatest effect on our overall parent 
Company audit.
Our procedures included:
•	 Tests of detail: We compared the carrying 
amount of the investment with the relevant 
subsidiary’s draft statutory balance sheet to 
identify whether its net assets, being an 
approximation of its minimum recoverable 
amount, was in excess of its carrying amount 
and assessed whether the subsidiary has 
historically been profit-making.
•	 Assessing subsidiary audits: Assessed the 
work performed by the subsidiary audit team 
and considered the results of that work on the 
investment subsidiary’s profits and net assets.
We performed the tests above rather than seeking 
to rely on any of the Group’s controls because the 
nature of the balance is such that we would expect 
to obtain audit evidence primarily through the 
detailed procedures described.
Our results
•	 We found the Company’s conclusion that there is 
no impairment of its investment in its subsidiary 
to be acceptable (2023 result: acceptable).
Last year, in response to a material release of uncertain tax provisions, we reported “provision for uncertain tax positions” as a key audit matter. We 
continue to perform procedures over provisions for uncertain tax positions. However, as there are no material changes in the current period, we have 
not assessed this as one of the most significant risks in our current year audit and, therefore, it is not separately identified in our report this year as a 
key audit matter.

3. Our application of materiality and 
an overview of the scope of our audit
Our application of materiality
Materiality for the Group financial statements 
as a whole was set at £3.2 million (2023: 
£3.2 million), determined with reference to 
a benchmark of Group revenue of which it 
represents 0.3% (2023: 0.3%).
We consider total revenue to be the most 
appropriate benchmark as it provides a more 
stable measure year on year than Group profit 
before tax.
Materiality for the parent Company financial 
statements as a whole was set at £0.9 million 
(2023: £2.9 million), determined with reference 
to a benchmark of parent Company total assets, 
of which it represents 0.2% (2023: 0.6%).
In line with our audit methodology, our 
procedures on individual account balances 
and disclosures were performed to a lower 
threshold, performance materiality, so as to 
reduce to an acceptable level the risk that 
individually immaterial misstatements in individual 
account balances add up to a material amount 
across the financial statements as a whole.
Performance materiality was set at 75% 
(2023: 75%) of materiality for the financial 
statements as a whole, which equates to £2.4 
million (2023: £2.4 million) for the Group and 
£0.67 million (2023: £2.2 million) for the parent 
Company. We applied this percentage in our 
determination of performance materiality 
because we did not identify any factors 
indicating an elevated level of risk.
We agreed to report to the audit committee 
any corrected or uncorrected identified 
misstatements exceeding £160,000 (2023: 
£160,000), in addition to other identified 
misstatements that warranted reporting on 
qualitative grounds.
Overview of the scope of our audit
This year, we applied the revised group auditing 
standard in our audit of the consolidated financial 
statements. The revised standard changes how 
an auditor approaches the identification of 
components, and how the audit procedures are 
planned and executed across components.
In particular, the definition of a component has 
changed, shifting the focus from how the entity 
prepares financial information to how we, as the 
group auditor, plan to perform audit procedures to 
address group risks of material misstatement 
(“RMMs”). Similarly, the group auditor has an 
increased role in designing the audit procedures 
as well as making decisions on where these 
procedures are performed (centrally and/or at 
component level) and how these procedures 
are executed and supervised. As a result, we 
assess scoping and coverage in a different way 
and comparisons to prior period coverage figures 
are not meaningful. In this report we provide an 
indication of scope coverage on the new basis.
We performed risk assessment procedures to 
determine which of the Group’s components are 
likely to include risks of material misstatement to 
the Group financial statements and which 
procedures to perform at these components to 
address those risks.

GOVERNANCE

We visited 3 component auditors in the US and 
UK to assess the audit risks and strategy. Video 
and telephone conference meetings were also 
held with these component auditors and others 
that were not physically visited. At these visits 
and meetings, the findings reported to the 
Group team were discussed in more detail, and 
any further work required by the Group team 
was then performed by the component auditors.
We inspected the work performed by the 
component auditors for the purpose of the 
Group audit and evaluated the appropriateness 
of conclusions drawn from the audit evidence 
obtained and consistencies between 
communicated findings and work performed.

We have considered the potential impacts of 
climate change on the financial statements as 
part of planning our audit.
Climate change impacts the Group in a variety 
of ways including the impact of climate risk 
on the substitution of existing products 
and services with lower emissions options, 
increased costs to transition to lower emissions 
technology and the impact on useful lives of 
assets from physical and obsolescence risks. 
There is also potential reputational risk associated 
with the Group’s delivery of its climate related 
initiatives, and greater emphasis on climate related 
narrative and disclosure in the annual report.
As part of our audit we have made enquiries of 
management to understand the extent of the 
potential impact of climate change risk on the 
Group’s financial statements. We have performed 
a risk assessment of how the impact of climate 
change may affect the financial statements and 
our audit. We held discussions with our own 
climate change professionals to challenge our risk 
assessment, including the goodwill impairment 
assessment, the estimates made regarding useful 
economic lives of property, plant and equipment, 
and the valuation of inventory, recoverability of 
trade receivables and going concern. Taking into 
account the extent of headroom on goodwill, the 
expected remaining useful lives of property, plant 
and equipment, the nature of customers and 
products, our assessment is that the climate 
related risks to the Group’s business, strategy and 
financial planning did not have a significant impact 
on our key audit matters given the nature of the 
Group’s operations and knowledge gained of its 
impact on critical accounting estimates during our 
risk assessment procedures and testing.
We have read the Group’s and the parent 
Company’s disclosure of climate related 
information in the front half of the annual report 
as set out on pages 14 to 24 and considered 
consistency with the financial statements and 
our audit knowledge.
5. Going concern
The directors have prepared the financial 
statements on the going concern basis as they 
do not intend to liquidate the Group or the parent 
Company or to cease their operations, and as 
they have concluded that the Group’s and the 
parent Company’s financial position means that 
this is realistic. They have also concluded that 
there are no material uncertainties that could 
have cast significant doubt over their ability to 
continue as a going concern for at least a year 
from the date of approval of the financial 
statements (“the going concern period”). 
In total, we identified 31 components, having 
considered our evaluation of the Group’s legal 
and operational structure, and our ability to 
perform audit procedures centrally.
Of those, we identified only 1 quantitatively 
significant component which contained the 
largest percentage of total revenue of the Group, 
for which we performed audit procedures.
We also identified 13 components as requiring 
special audit consideration, owing to the Group 
risk relating to revenue.
Additionally, having considered qualitative and 
quantitative factors, we selected 9 components 
with accounts contributing to the specific RMMs 
of the Group financial statements.
Accordingly, we performed audit procedures 
on 23 components, of which we involved 
component auditors in performing the audit 
work on 22 components. We performed the 
audit of the parent Company.
We approved the component materialities, 
ranging from £0.4m to £1.35m, having regard 
to the mix of size and risk profile of the Group 
across the components.
3. Our application of materiality and 
an overview of the scope of our audit 
continued 
Our audit procedures covered 88% of Group 
revenue. We performed audit procedures in 
relation to components that accounted for 90% 
of Group profit before tax and 89% of Group 
total assets.
For the remaining components for which we 
performed no audit procedures, no component 
represented more than 2% of Group total 
revenue, or Group total assets. We performed 
analysis at an aggregated Group level to 
re-examine our assessment that there is not 
a reasonable possibility of a material 
misstatement in these components.
Impact of controls on our group audit
The Group utilises a diverse range of IT systems 
across its operating businesses. For all of the 
components that were subject to audit 
procedures, we obtained an understanding of the 
relevant IT systems for the purposes of our audit 
work. On this audit we take a predominantly 
substantive approach in all areas of the audit due 
to the diverse nature of the Group’s information 
systems and IT general controls, as well as 
having considered the efficiency and 
effectiveness of approaches to gaining the 
appropriate audit evidence. As a result, we 
appropriately planned additional substantive 
testing, including in the key transactional areas 
of revenue, purchases and inventory.
As we did not rely on automated controls on 
journal entries, our work to respond to the risk 
of management override of controls considered 
both automated and manual journals and 
additional testing as necessary.
Group auditor oversight
As part of establishing the overall Group audit 
strategy and plan, we conducted the risk 
assessment and planning discussion meetings 
with component auditors to discuss Group audit 
risks relevant to the components.
We used our knowledge of the Group, its 
industry, and the general economic environment 
to identify the inherent risks to its business model 
and analysed how those risks might affect the 
Group’s and parent Company’s financial 
resources or ability to continue operations over 
the going concern period. The risks that we 
considered most likely to adversely affect the 
Group’s and parent Company’s available financial 
resources and/or metrics relevant to debt 
covenants over this period were:
•	 The impact of a global economic downturn 
on the Group’s key end markets, including 
increasing inflationary pressures; and
•	 The volatility of and disruption to supply chain 
affecting critical materials or components.
We considered whether these risks could 
plausibly affect the liquidity or covenant 
compliance in the going concern period by 
comparing severe, but plausible downside 
scenarios that could arise from these risks 
individually and collectively against the level 
of available financial resources and covenants 
indicated by the Group’s financial forecasts.
We considered whether the going concern 
disclosure in note 2 to the financial statements 
gives a full and accurate description of the 
directors’ assessment of going concern, 
including the identified risks and dependencies. 
We assessed the completeness of the going 
concern disclosure.
Our conclusions based on this work:
•	 we consider that the directors’ use of the 
going concern basis of accounting in the 
preparation of the financial statements is 
appropriate;
•	 we have not identified, and concur with the 
directors’ assessment that there is not, a 
material uncertainty related to events or 
conditions that, individually or collectively, 
may cast significant doubt on the Group’s or 
parent Company’s ability to continue as a 
going concern for the going concern period;
•	 we have nothing material to add or draw 
attention to in relation to the directors’ 
statement in note 2 to the financial 
statements on the use of the going concern 
basis of accounting with no material 
uncertainties that may cast significant doubt 
over the Group and parent Company’s use of 
that basis for the going concern period, and 
we found the going concern disclosure in note 
2 to be acceptable; and
•	 the related statement under the UK Listing 
Rules set out on page 68 is materially 
consistent with the financial statements 
and our audit knowledge.
However, as we cannot predict all future events 
or conditions and as subsequent events may 
result in outcomes that are inconsistent with 
judgements that were reasonable at the time 
they were made, the above conclusions are not 
a guarantee that the Group or the parent 
Company will continue in operation.

6. Fraud and breaches of laws and 
regulations – ability to detect
Identifying and responding to risks of 
material misstatement due to fraud
To identify risks of material misstatement 
due to fraud (“fraud risks”) we assessed events 
or conditions that could indicate an incentive 
or pressure to commit fraud or provide an 
opportunity to commit fraud. Our risk 
assessment procedures included:
•	 Enquiring of directors, those charged with 
governance, internal audit, management and 
inspection of policy documentation as to the 
Group’s high-level policies and procedures to 
prevent and detect fraud, including the internal 
audit function, and the Group’s channel for 
“whistleblowing”, as well as whether they 
have knowledge of any actual, suspected 
or alleged fraud.
•	 Reading Board and audit committee 
meeting minutes.
•	 Considering remuneration incentive schemes 
and performance targets for management 
and directors including the long-term incentive 
plan for Management remuneration.
•	 Considering announcements made by the 
group in respect of revised performance 
expectations for the year. 
•	 Using analytical procedures to identify 
any unusual or unexpected relationships.
•	 Our forensic specialists assisted us in 
designing and executing relevant audit 
procedures to respond to identifying 
fraud risks. This included holding 
a discussion between the forensic 
specialist and the engagement partner 
and engagement manager.
We communicated identified fraud risks 
throughout the audit team and remained alert 
to any indications of fraud throughout the audit. 
This included communication from the Group 
audit team to all component audit teams of 
relevant fraud risks identified at the Group level 
and request to all component audit teams to 
report to the Group audit team any instances 
of fraud that could give rise to a material 
misstatement at the Group level.
As required by auditing standards and taking into 
account possible pressures to meet profit 
targets and market consensus, we perform 
procedures to address the risk of management 
override of controls and the risk of fraudulent 
revenue recognition. In particular:
•	 the risk that revenue is misstated through 
recording revenues in the wrong period; 
•	 the risk that Group and component 
Management may be in a position to make 
inappropriate accounting entries; and
•	 the risk of bias in accounting estimates 
and judgements such as the warranty 
provision, provisions for uncertain tax 
positions, provisions for litigation 
and claims, and pension assumptions.
We did not identify any additional fraud risks.
We performed procedures including:
•	 Identifying journal entries and other 
adjustments to test for all full scope 
components based on risk criteria and 
comparing the identified entries to supporting 
documentation. These included those posted 
by unexpected individuals, journals posted to 
seldom used accounts, journals with certain 
descriptions, and those with unusual account 
pairings to revenue, cash and loans.
•	 Assessing whether the judgements made 
in making accounting estimates are 
indicative of a potential bias, in particular 
warranty provisions.
•	 Selecting a sample of revenue near year 
end and comparing the identified entries 
to support documentation to check that 
revenue is recognised in the appropriate 
accounting period.
We discussed with the audit committee matters 
related to actual or suspected fraud, for which 
disclosure is not necessary, and considered any 
implications for our audit.
Identifying and responding to risks of 
material misstatement due to non-
compliance with laws and regulations
We identified areas of laws and regulations that 
could reasonably be expected to have a material 
effect on the financial statements from our 
general commercial and sector experience and 
through discussion with the directors (as 
required by auditing standards), and discussed 
with the directors the policies and procedures 
regarding compliance with laws and regulations.
As the Group is regulated, our assessment 
of risks involved gaining an understanding 
of the control environment including the 
entity’s procedures for complying with 
regulatory requirements.
We communicated identified laws and 
regulations throughout our team and remained 
alert to any indications of non-compliance 
throughout the audit . This included 
communication from the Group audit team 
to all component audit teams of relevant laws 
and regulations identified at the Group level, 
and a request for all component auditors 
to report to the Group audit team any instances 
of noncompliance with laws and regulations 
that could give rise to a material misstatement 
at the Group level.
The potential effect of these laws and 
regulations on the financial statements 
varies considerably.
Firstly, the Group is subject to laws and 
regulations that directly affect the financial 
statements including financial reporting 
legislation (including related companies 
legislation), distributable profits legislation, 
pension scheme legislation and taxation 
legislation, and we assessed the extent of 
compliance with these laws and regulations 
as part of our procedures on the related 
financial statement items.
Secondly, the Group is subject to many other 
laws and regulations where the consequences 
of non-compliance could have a material effect 
on amounts or disclosures in the financial 
statements, for instance through the imposition 
of fines or litigation or the loss of the Group’s 
licence to operate. We identified the following 
areas as those most likely to have such an 
effect: health and safety, data protection 
regulation, environmental laws and regulations, 
anti-bribery and corruption, contract legislation, 
employment law and export laws and 
regulations, recognising the financial and 
regulated nature of the Group’s activities. 
Auditing standards limit the required audit 
procedures to identify non-compliance with 
these laws and regulations to enquiry of the 
directors and inspection of regulatory and legal 
correspondence, if any. Therefore if a breach of 
operational regulations is not disclosed to us or 
evident from relevant correspondence, an audit 
will not detect that breach.
Context of the ability of the audit to detect 
fraud or breaches of law or regulation
Owing to the inherent limitations of an audit, 
there is an unavoidable risk that we may not 
have detected some material misstatements in 
the financial statements, even though we have 
properly planned and performed our audit in 
accordance with auditing standards. For 
example, the further removed non-compliance 
with laws and regulations is from the events 
and transactions reflected in the financial 
statements, the less likely the inherently limited 
procedures required by auditing standards 
would identify it.
In addition, as with any audit, there remained 
a higher risk of non-detection of fraud, as these 
may involve collusion, forgery, intentional 
omissions, misrepresentations, or the override 
of internal controls. Our audit procedures are 
designed to detect material misstatement. 
We are not responsible for preventing 
non-compliance or fraud and cannot be 
expected to detect non-compliance with 
all laws and regulations.
7. We have nothing to report on the other 
information in the Annual Report
The directors are responsible for the other 
information presented in the Annual Report 
together with the financial statements. Our 
opinion on the financial statements does not 
cover the other information and, accordingly, 
we do not express an audit opinion or, except 
as explicitly stated below, any form of assurance 
conclusion thereon.
Our responsibility is to read the other 
information and, in doing so, consider whether, 
based on our financial statements audit work, 
the information therein is materially misstated or 
inconsistent with the financial statements or our 
audit knowledge. Based solely on that work we 
have not identified material misstatements in 
the other information.
SENIOR PLC ANNUAL REPORT AND ACCOUNTS 2024

GOVERNANCE

Strategic report and directors’ report
Based solely on our work on the 
other information:
•	 we have not identified material 
misstatements in the strategic report 
and the directors’ report;
•	 in our opinion the information given in those 
reports for the financial year is consistent 
with the financial statements; and
•	 in our opinion those reports have been 
prepared in accordance with the Companies 
Act 2006.
Directors’ remuneration report
In our opinion the part of the Directors’ 
Remuneration Report to be audited has been 
properly prepared in accordance with the 
Companies Act 2006.
Disclosures of emerging and principal risks 
and longer-term viability
We are required to perform procedures to 
identify whether there is a material 
inconsistency between the directors’ 
disclosures in respect of emerging and principal 
risks and the viability statement, and the 
financial statements and our audit knowledge.
Based on those procedures, we have nothing 
material to add or draw attention to in relation to:
•	 the directors’ confirmation within the viability 
statement on page 68 that they have carried 
out a robust assessment of the emerging 
and principal risks facing the Group, including 
those that would threaten its business model, 
future performance, solvency and liquidity;
•	 the Risks and uncertainties disclosures 
describing these risks and how emerging risks 
are identified, and explaining how they are 
being managed and mitigated; and
•	 the directors’ explanation in the viability 
statement of how they have assessed the 
prospects of the Group, over what period they 
have done so and why they considered that 
period to be appropriate, and their statement 
as to whether they have a reasonable 
expectation that the Group will be able to 
continue in operation and meet its liabilities 
as they fall due over the period of their 
assessment, including any related disclosures 
drawing attention to any necessary 
qualifications or assumptions.
We are also required to review the Viability 
Statement, set out on page 68 under the UK 
Listing Rules. Based on the above procedures, 
we have concluded that the above disclosures 
are materially consistent with the financial 
statements and our audit knowledge.
Our work is limited to assessing these matters 
in the context of only the knowledge acquired 
during our financial statements audit. As we 
cannot predict all future events or conditions and 
as subsequent events may result in outcomes 
that are inconsistent with judgements that were 
reasonable at the time they were made, the 
absence of anything to report on these 
statements is not a guarantee as to the Group’s 
and parent Company’s longer-term viability.
Corporate governance disclosures
We are required to perform procedures 
to identify whether there is a material 
inconsistency between the directors’ corporate 
governance disclosures and the financial 
statements and our audit knowledge.
Based on those procedures, we have 
concluded that each of the following is 
materially consistent with the financial 
statements and our audit knowledge:
•	 the directors’ statement that they consider 
that the annual report and financial 
statements taken as a whole is fair, balanced 
and understandable, and provides the 
information necessary for shareholders to 
assess the Group’s position and performance, 
business model and strategy;
•	 the section of the annual report describing 
the work of the audit committee, including 
the significant issues that the audit 
committee considered in relation to the 
financial statements, and how these issues 
were addressed; and
•	 the section of the annual report that 
describes the review of the effectiveness 
of the Group’s risk management and internal 
control systems.
We are required to review the part of the 
Corporate Governance Statement relating to the 
Group’s compliance with the provisions of the 
UK Corporate Governance Code specified by 
the UK Listing Rules for our review. 
We have nothing to report in this respect.
8. We have nothing to report on the other 
matters on which we are required to 
report by exception
Under the Companies Act 2006, we are 
required to report to you if, in our opinion:
•	 adequate accounting records have not been 
kept by the parent Company, or returns 
adequate for our audit have not been received 
from branches not visited by us; or
•	 the parent Company financial statements 
and the part of the Directors’ Remuneration 
Report to be audited are not in agreement 
with the accounting records and returns; or
•	 certain disclosures of directors’ remuneration 
specified by law are not made; or
•	 we have not received all the information 
and explanations we require for our audit.
We have nothing to report in these respects.
9. Respective responsibilities
Directors’ responsibilities
As explained more fully in their statement set 
out on page 110, the directors are responsible 
for: the preparation of the financial statements 
including being satisfied that they give a true 
and fair view; 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; assessing the Group and parent 
Company’s ability to continue as a going 
concern, disclosing, as applicable, matters 
related to going concern; and using the going 
concern basis of accounting unless they either 
intend to liquidate the Group or the parent 
Company or to cease operations, or have no 
realistic alternative but to do so.
Auditor’s responsibilities
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 
our opinion in an auditor’s report. Reasonable 
assurance is a high level of assurance, but does 
not 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 
aggregate, they could reasonably be expected 
to influence the economic decisions of users 
taken on the basis of the financial statements.
 A fuller description of our responsibilities 
is provided on the FRC’s website at 
www.frc.org.uk/auditorsresponsibilities.
The Company is required to include these 
financial statements in an annual financial report 
prepared under Disclosure Guidance and 
Transparency Rule 4.1.17R and 4.1.18R. This 
auditor’s report provides no assurance over 
whether the annual financial report has been 
prepared in accordance with those requirements.
10. The purpose of our audit work and to 
whom we owe our responsibilities
This report is made solely to the Company’s 
members, as a body, in accordance with 
Chapter 3 of Part 16 of the Companies Act 
2006. Our audit work has been undertaken so 
that we might state to the Company’s members 
those matters we are required to state to them 
in an auditor’s report and for no other purpose. 
To the fullest extent permitted by law, we do 
not accept or assume responsibility to anyone 
other than the Company and the Company’s 
members, as a body, for our audit work, for this 
report, or for the opinions we have formed.

CONSOLIDATED CASH FLOW STATEMENT
FOR THE YEAR ENDED 31 DECEMBER 2024
SENIOR PLC ANNUAL REPORT AND ACCOUNTS 2024

FINANCIAL  
STATEMENTS

NOTES TO THE CONSOLIDATED 
FINANCIAL STATEMENTS 
1. General information
Senior plc is a Company incorporated in England and Wales under the 
Companies Act 2006. The address of the registered office is given on the 
inside back cover. The nature of the Group’s operations and its principal 
activities are set out in Note 3 and on pages 1 to 69.

Items included in the Financial Statements of each of the Group’s entities 
are measured using the currency of the primary economic environment 
in which the entity operates (the functional currency). These Financial 
Statements are presented in Pounds Sterling, which is the Company’s 
functional and the Group’s presentation currency.
2. Significant accounting policies
Basis of accounting
These Financial Statements have been prepared in accordance with 
UK-adopted international accounting standards. They have been prepared 
on the historical cost basis, except for the revaluation of certain financial 
instruments and retirement benefit costs measured in accordance with 
IAS 19.
Going concern
In determining the appropriate basis of preparation of the Financial 
Statements for the year ended 31 December 2024, the Directors are 
required to consider whether the Group and Parent Company can 
continue in operational existence for the foreseeable future, being 
a period of at least 12 months from the date of approval of these 
Financial Statements (the going concern period).
The Board has applied a robust process to assess the resilience of the 
forecast out-turns. This assessment included applying severe but 
plausible downside risks as set out in the Viability Statement on page 68. 
To address these risks the Board has considered mitigating factors 
within the Group and Parent Company’s control that could be employed 
that would address the impact and provide options to the Group and 
Parent Company.
The Group has two covenants for committed borrowing facilities, 
which are tested at June and December: the Group’s net debt to 
EBITDA (defined in the Notes to the Financial Headlines on page 1) 
must not exceed 3.0x and interest cover, the ratio of EBITDA to interest 
must be higher than 3.5x. At 31 December 2024, the Group’s net debt 
to EBITDA was 1.8x and interest cover was 7.0x, both comfortably 
within covenant limits.
Based on the above assessment, the Board has concluded that the Group 
and Parent Company will continue to have adequate financial resources to 
realise its assets and discharge its liabilities as they fall due over the going 
concern period. Accordingly, the Directors have formed the judgment that 
it is appropriate to prepare these Consolidated Financial Statements and 
the Parent Company financial statements on the going concern basis.
Changes in accounting policies
At the date of authorisation of these Financial Statements, there are no 
relevant and material new standards, amendments to standards or 
interpretations which are effective for the year ended 31 December 2024.
IFRS 18 Presentation and Disclosure in Financial Statements has been 
issued but is not effective until 2027. Its impact on the financial 
statements of Senior Plc is not yet known.
Basis of consolidation
The Consolidated Financial Statements incorporate the Financial 
Statements of Senior plc and the entities controlled by it (its subsidiaries) 
made up to 31 December 2024. Control is achieved when Senior plc has 
the power to govern the financial and operating policies of an invested 
entity so as to obtain benefits from its activities.
Acquisitions of subsidiaries and businesses are accounted for using the 
acquisition method. The consideration transferred for each acquisition 
is the aggregate of the fair values (at the date of exchange) of assets 
transferred, liabilities incurred or assumed, and equity interests issued 
by the Group. The consideration transferred includes the fair value of any 
asset or liability resulting from a contingent consideration arrangement. 
Acquisition-related costs are expensed as incurred. Identifiable assets 
acquired and liabilities and contingent liabilities assumed are measured 
initially at their fair values at the acquisition date. On an acquisition-by- 
acquisition basis, the Group recognises any non-controlling interest in 
the acquiree either at fair value or at the non-controlling interest’s 
proportionate share of the acquiree’s net assets.
The 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.
The results of joint ventures are accounted for using the equity 
accounting method.
Where necessary, adjustments are made to the Financial Statements of 
subsidiaries to bring the accounting policies used in line with those used 
by the Group.
All intra-group transactions, balances, income and expenses are 
eliminated on consolidation.
Goodwill
Goodwill arising on consolidation, which was acquired in a business 
combination, is measured as the excess of the consideration transferred, 
the amount of any non-controlling interest in the acquiree and the 
acquisition date fair value of any previous equity interest in the acquiree 
over the fair value of the Group’s share of the identifiable net assets 
acquired. Goodwill is recognised as an asset and allocated, at acquisition, 
to the group of cash-generating units (CGU groups) that are expected to 
benefit from that business combination. If the consideration transferred, 
the amount of any non-controlling interest in the acquiree and the 
acquisition date fair value of any previous equity interest in the acquiree is 
less than the fair value of the net assets acquired (i.e. bargain purchase), 
the difference is credited to the Consolidated Income Statement in the 
period of acquisition.
CGU groups to which goodwill has been allocated are tested for 
impairment at least annually and reviewed for indicators of impairment 
at the Balance Sheet date. If impairment indicators exist, the individual 
assets within the CGUs, and the individual CGUs excluding goodwill, 
are tested for impairment before the CGU group is tested for impairment. 
Any impairment is recognised immediately through the Consolidated 
Income Statement and is not subsequently reversed. The determination 
of the recoverable amount of the CGU group is disclosed in the Notes to 
the Financial Statements (Note 13). If the recoverable amount of the CGU 
group is less than its carrying amount, the impairment loss is allocated 
first to reduce the carrying amount of any goodwill allocated to the CGU 
group and then to the other assets of the CGU group pro rata 
on the basis of the carrying amount of each asset in the CGU group.
On disposal of a subsidiary or part thereof, the attributable amount of 
goodwill is included in the determination of the profit or loss on disposal.
Goodwill acquired in a business combination prior to the date of transition 
to IFRS has been retained at the previous UK GAAP amount subject to 
being tested for impairment at that date. 
Revenue recognition
The Group predominantly has one revenue stream relating to engineered 
components or systems (products), which are customer specific, with 
a secondary revenue stream of funded development revenue. Both 
streams have identifiable customer contracts and pricing specific 
performance obligations.

STRATEGIC  
REPORT

FINANCIAL  
STATEMENTS
ADDITIONAL  
INFORMATION

The transaction price is the amount of consideration to which an entity 
expects to be entitled in exchange for transferring promised goods or 
services to a customer. Revenue is recognised net of discounts, VAT and 
other sales-related taxes. The determination of the transaction price is 
based upon pricing specified in the customer contract i.e. a price per unit.
Revenue is recognised as the identified performance obligations 
are satisfied.
The performance obligation for goods is a specific point in time when 
the customer obtains control, which is upon delivery or when available 
for collection. Allocation of transaction price to performance obligations 
is given in the contract i.e. a unit delivered or available for collection.
The performance obligation for development revenue is a specific point 
in time when the customer obtains control of the output, for example 
a first article good, which is the acceptance milestone specified in the 
customer contract.
Any portion of a change in transaction price that is allocated to a satisfied 
performance obligation is recognised as revenue – or as a reduction in 
revenue – when the transaction price changes.
Dividend income from investments is recognised when the shareholders’ 
legal rights to receive payment have been established, with the related 
cashflows being classified as investing activities within the Consolidated 
Cash Flow Statement.
Interest
Interest receivable/payable is credited/charged to the Consolidated 
Income Statement using the effective interest method.
Deferred and contingent consideration related to business combinations 
which is paid, including changes in fair value since acquisition date, 
is classified as investing activities within the Consolidated Cash Flow 
Statement. Any cash settlement relates to obtaining control rather than 
settlement of financing provided by the seller. Changes in fair value since 
the acquisition date are classified as finance income/expense.
Leasing
At inception of a contract, the Group assesses whether a contract is, or 
contains, a lease. A contract is, or contains, a lease if the contract conveys 
a right to control the use of an identified asset for a period of time in 
exchange for consideration. The assessment of control includes whether 
the Group has a right to obtain substantially all of the economic benefits 
from the use of the asset throughout the period of use and the right to 
direct the use of the asset.
As a lessee, the Group recognises a right-of-use asset and lease liability 
at the lease commencement date. The right-of-use asset is initially 
measured at cost, which comprises the initial amount of the lease 
liability adjustment for any lease payments made at or before the 
commencement date, plus any initial direct costs incurred and an estimate 
of costs to dismantle or restore the underlying asset, less any lease 
incentives received.
Lease payments comprise fixed payments and variable lease payments 
based on an index or rate. The right-of-use asset is subsequently 
depreciated using the straight-line method from the commencement date 
to the earlier of the end of the useful life of the asset or the end of the 
lease term. The lease term includes optional extensions or terminations 
which are reasonably certain to be exercised by the Group. These optional 
terms are reassessed periodically or when there is a significant event 
which affects the lease. The estimated useful lives of the right-of-use 
assets are determined on the same basis as those of property, plant and 
equipment. Periodically the right-of-use asset is reduced for impairment, 
if necessary, as well as re-measurements of the lease liability.
The lease liability is measured at amortised cost using the effective 
interest method, which is initially equal to the present value of lease 
payments that are not paid at the commencement date, discounted 
using an incremental borrowing rate determined on a lease portfolio 
basis. The lease liability is re-measured either as a modification or 
reassessment. Modification occurs where there is a change in terms, 
such as rental payments, which did not form part of the original terms 
of the contract. In this case, the lease liability is re-measured using the 
revised terms and a revised incremental borrowing rate at the 
modification date. Reassessment occurs where there are changes within 
the scope of the original terms of the contract, such as rental payment 
changes with reference to an index. For reassessment changes, the lease 
liability is re-measured in the same way as for a modification, except for 
the incremental borrowing rate, which is not changed from the original 
commencement date of the contract.
The Group has elected not to recognise right-of-use assets and lease 
liabilities for short-term leases which have a lease term of 12 months or 
less and leases of low-value assets. The Group recognises the lease 
payments associated with these leases as an expense on a straight-line 
basis over the lease term. When the Group acts as a lessor, it determines 
at lease inception whether each lease is a finance lease or an operating 
lease. To classify each lease, several indicators are assessed, such as the 
present value of the lease payments amounting to at least substantially all 
of the fair value of the asset. When the Group is an intermediate lessor, 
it accounts for its interest in the head lease and the sub-lease separately. 
The Group assesses the classification of the sub-lease with reference to 
the right-of-use asset arising from the head lease. The Group recognises 
lease payments received under operating leases as income on a straight- 
line basis over the lease term.
Foreign currencies
Transactions in currencies other than the functional currency are recorded 
at the rates of exchange prevailing on the date of the transaction. At each 
Balance Sheet date, monetary assets and liabilities that are denominated 
in foreign currencies are retranslated at the rates prevailing on the Balance 
Sheet date. Non-monetary items carried at fair value that are denominated 
in foreign currencies are translated at the rates prevailing at the date when 
the fair value was determined. Non-monetary items that are measured at 
historical cost in a foreign currency are not retranslated. Gains and losses 
arising on retranslation are included in profit or loss for the period, except 
for exchange differences arising on non-monetary assets and liabilities 
where the changes in fair value are recognised directly in equity, subject 
to meeting the requirements under IAS 21.
In order to hedge its exposure to certain foreign exchange risks, the Group 
enters into forward exchange contracts (see section below on derivative 
financial instruments and hedging for details of the Group’s accounting 
policies in respect of such derivative financial instruments).
On consolidation, the assets and liabilities of the Group’s overseas 
operations are translated at exchange rates prevailing on the Balance 
Sheet date. Income and expense items are translated at the average 
exchange rates for the period. Exchange rate differences arising, if any, 
are classified as equity and transferred to the Group’s translation reserve. 
Such translation differences are recognised as income or expense in the 
period in which the operation is disposed.
Goodwill and fair value adjustments arising on the acquisition of a foreign 
entity are treated as assets and liabilities of the foreign entity and 
translated at the closing rate on the relevant Balance Sheet date.

Government grants
Government grants received for items of a revenue nature are recognised 
as income over the period necessary to match them with the related 
costs, which are deducted in reporting the related expense and presented 
net of the costs to which they relate. Government grants relating to 
investment in property, plant and equipment are deducted from the initial 
carrying value of the related capital asset.
Retirement benefit costs
Payments to defined contribution retirement plans are charged as an 
expense as they fall due. Payments made to state-managed retirement 
benefit plans are dealt with as payments to defined contribution plans 
where the Group’s obligations under the plans are equivalent to those 
arising in a defined contribution retirement plan.
For defined benefit retirement plans, the cost of providing benefits 
is determined using the Projected Unit Method, with full actuarial 
valuations being carried out on a triennial basis, and updated at each 
Balance Sheet date. Actuarial gains and losses are recognised in full 
in the period in which they occur. They are recognised outside the 
Consolidated Income Statement and are presented in the Statement 
of Comprehensive Income.
Past service cost is recognised as an expense at the earlier of a plan 
amendment, curtailment, or restructuring.
The retirement benefit obligation recognised in the Consolidated Balance 
Sheet represents the present value of the defined benefit obligation, 
and as reduced by the fair value of scheme assets.
Taxation
Provisions for uncertain tax positions are included within current tax 
liabilities on the Consolidated Balance Sheet representing Management’s 
best estimate of the likely cash outflow related to the uncertainty. There 
are transactions and activities that the Group engages in where the 
ultimate tax determination is uncertain and a provision may be made 
against the tax benefit. For example, the Group seeks to price 
transactions between Group companies on an arm’s-length basis and in 
compliance with OECD transfer pricing principles and the laws of the 
relevant jurisdictions. The application of OECD principles and local tax 
laws require interpretation, and accordingly involves the application of 
judgment and is open to challenge by the relevant tax authorities. This 
gives rise to a level of uncertainty. Provisions for uncertain tax positions 
are established in accordance with IFRIC 23 based on an assessment of 
the range of likely tax outcomes in open years and reflecting the strength 
of technical arguments. Amounts are provided for individual tax 
uncertainties based on Management’s assessment of whether the most 
likely amount or an expected amount based on a probability weighted 
methodology is the more appropriate predictor of amounts that the 
company is ultimately expected to settle. When making this assessment, 
the Group utilises specialist in-house tax knowledge and experience and 
takes into consideration specialist tax advice from third-party advisers on 
specific items. 
Deferred tax is the tax expected to be payable or recoverable 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, and is accounted for using the Balance 
Sheet liability method. Deferred tax liabilities are generally recognised 
for all taxable temporary differences, including for taxable temporary 
differences arising on investments in subsidiaries and associates, 
and interests in joint ventures, 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. 
Deferred tax assets are recognised to the extent that it is probable that 
future taxable profits will be available for their utilisation before their 
expiry. Amounts will be recognised first to the extent that taxable 
temporary differences exist and it is considered probable that they will 
reverse and give rise to future taxable profits against which losses or 
other assets may be utilised before their expiry. Assets will then be 
recognised to the extent that forecasts or other evidence support the 
availability of future profits against which assets may be realised. 
Deferred tax assets and liabilities are not recognised if the temporary 
difference arises from goodwill or from the initial recognition of goodwill 
(other than in a business combination) of other assets and liabilities in a 
transaction that affects neither the Group’s taxable profit nor its 
accounting profit. 
The carrying value of deferred tax assets is reviewed at each Balance 
Sheet date and reduced to the extent it is no longer probable that 
sufficient taxable profits will be available to allow all or part of the deferred 
tax asset to be recovered. Deferred tax is calculated at the tax rates that 
are expected to apply in the period when the liability is settled or the asset 
is realised based on tax laws and rates that have been enacted at the 
Balance Sheet date. Deferred tax is charged or credited in the 
Consolidated Income Statement, except when it relates to items charged 
or credited to Other Comprehensive Income or directly to Equity, in which 
case the deferred tax is also dealt with in Other Comprehensive Income 
or Equity.
Property, plant and equipment
Land and buildings held for use in the production or supply of goods 
or services, or for administrative purposes, are stated in the Balance 
Sheet at their historical cost, or at modified historical cost, being a 
revaluation undertaken in 1988 which has been taken as the effective 
cost on transition to IFRS. Land and buildings were revalued to fair 
value at the date of revaluation. The Group does not intend to conduct 
annual revaluations. 
Plant and equipment are stated at cost less accumulated depreciation and 
any recognised impairment loss. Depreciation is charged to write off the 
cost of an asset on a straight-line basis over the estimated useful life of 
the asset, and is charged from the time an asset becomes available for its 
intended use. Annual rates are as follows:
Freehold land
Nil
Freehold buildings
2%
Right-of-use land 
and buildings
on the same basis as owned assets or, 
where shorter, over the lease term
Leasehold building 
improvements
on the same basis as owned assets or, 
where shorter, over the lease term
Plant and equipment
5%–33%
Right-of-use plant and 
equipment
on the same basis as owned assets or, 
where shorter, over the lease term
The Group primarily leases land and buildings for manufacturing use. 
The lease term, including options to extend which are reasonably certain, 
typically range from two to fifteen years. The Group also leases plant 
and equipment, including office equipment, vehicles and manufacturing 
equipment, with lease terms typically ranging from one to four years.
The gain or loss arising on the disposal or retirement of an asset is 
determined as the difference between the sale proceeds and the carrying 
amount of the asset at disposal and is recognised in the Consolidated 
Income Statement.

Internally generated intangible assets – development expenditure
An intangible asset arising from unfunded development work shall be 
recognised if the following can be demonstrated:
i.	 the asset can be separately identified.
ii.	 it is probable that the asset created will generate future 
economic benefits.
iii.	 the development cost of the asset can be measured reliably 
during its development.
iv.	 it is technically feasible to complete the asset so that it will be 
available for use or sale. 
v.	 there is intention to complete the asset and use or sell it. 
vi.	the Group has ability to use or sell the asset. 
vii.	the Group has availability of adequate technical, financial and other 
resources to complete the development work and to use or sell 
the asset. 
Internally generated intangible assets are amortised on a straight-line 
basis over their useful lives. Costs incurred in relation to funded 
development work are accumulated in inventory and are recognised when 
the related billings are made. Any amounts held in inventory are subject to 
normal inventory valuation principles. Expenditure on research, design and 
other development activities, that do not meet the capitalisation criteria 
above, is recognised as an expense in the period in which it is incurred.
Other intangible assets
Other intangible assets include computer software and intangible assets 
acquired as part of a business combination. The cost of acquiring 
computer software (including associated implementation and 
development costs where applicable) is classified as an intangible asset. 
Costs associated with maintaining computer software programs are 
recognised as an expense as incurred. Capitalised computer software is 
amortised over its estimated useful life of between three and five years 
on a straight-line basis, and is stated at cost less accumulated 
amortisation and impairment losses. Intangible assets acquired as part of 
a business combination principally comprise qualified parts list, customer 
relationships, contracts and trade names. They are shown at fair value at 
the date of acquisition less accumulated amortisation. At the Balance 
Sheet date, Intangible assets which incurred amortisation during the year, 
are being amortised at rates of between 16 and 18% on a straight-line 
basis since acquisition date.
Impairment of tangible and intangible assets excluding goodwill
At each Balance Sheet date, the Group reviews the carrying amounts 
of its tangible and intangible assets to determine whether there is any 
indication that those assets have suffered an impairment loss. If any 
such indication exists, the recoverable amount of the asset is estimated 
in order to determine the extent of the impairment loss (if any). Where 
the asset does not generate cash flows that are independent from 
other assets, the Group estimates the recoverable amount of the 
cash-generating unit to which the asset belongs.
The recoverable amount is the higher of the fair value less the costs to 
sell and the value in use. In assessing the value in use, the estimated 
future cash flows are discounted to their present value using a pre-tax 
discount rate that reflects current market assessments of the time value 
of money and the risks specific to the asset for which the estimates of 
future cash flows have not been adjusted.
If the recoverable amount of an asset is estimated to be less than its 
carrying amount, the carrying amount of the asset is reduced to its 
recoverable amount. An impairment loss is recognised as an expense 
immediately, unless the relevant asset is carried at a revalued amount, 
in which case the impairment loss is treated as a revaluation decrease.
Where an impairment loss subsequently reverses, the carrying amount of 
the asset is increased to the revised estimate of its recoverable amount, 
so that the increased carrying amount does not exceed the carrying 
amount that would have been determined had no impairment loss been 
recognised for the asset in prior years. A reversal of an impairment loss is 
recognised as income immediately, unless the relevant asset is carried at 
a revalued amount, in which case the reversal of the impairment loss is 
treated as a revaluation increase.
Inventories
Inventories are stated at the lower of cost and net realisable value. Costs 
comprise direct materials and, where applicable, direct labour costs and 
an appropriate allocation of production overheads. Cost is calculated using 
the first-in, first-out method. Net realisable value represents the estimated 
selling price less the estimated costs of completion and the costs to be 
incurred in marketing, selling and distribution.
Financial instruments
Financial assets and liabilities are recognised when the Group becomes 
a party to the contractual provisions of the relevant instrument and 
derecognised when it ceases to be a party to such provisions.
Financial instruments are classified as cash and cash equivalents, bank 
overdrafts and loans, lease liabilities, trade receivables, trade payables, 
deferred consideration receivable or payable, contingent consideration 
payable, other receivables and other payables, as appropriate.
Non-derivative financial assets are categorised as Financial assets at 
amortised cost and non-derivative financial liabilities are categorised as 
Financial liabilities at amortised cost. Derivative financial assets and 
liabilities that are not designated and effective as hedging instruments 
are categorised as financial assets at fair value through profit or loss 
and financial liabilities at fair value through profit or loss, respectively. 
The classification depends on the nature and purpose of the financial 
assets and liabilities and is determined at the time of initial recognition.
Trade receivables
Trade receivables do not carry any interest and are stated at their nominal 
value as reduced by loss allowance. The Group has elected to measure 
loss allowance for trade receivables at an amount equal to the lifetime 
expected credit losses (ECLs), which are based on quantitative and 
qualitative credit risk assessments, using historical and forward-looking 
information. Changes in the carrying amounts of the loss allowance are 
recognised in the Consolidated Income Statement.
Trade receivables in default are considered uncollectible and are 
written off against the loss allowance. The Group considers a trade 
receivable to be in default when the customer is experiencing significant 
financial difficulties, bankruptcy, financial reorganisation or is in default 
or delinquent in paying its credit obligations to the Group in full. 
Subsequent recoveries of amounts previously written off are credited 
against the loss allowance.
Trade receivables are derecognised when reverse factored, without 
recourse, through schemes with financial institution counterparties 
who assume the risk of non-payment by the customer. Derecognition 
occurs when cash is received from the financial institution (less reverse 
factoring discount). For further details, see Strategic Report and the 
financial instrument credit risk section in the notes to the Consolidated 
Financial Statements.
Cash and cash equivalents
Cash and cash equivalents comprise cash at bank and other short-term 
highly liquid investments that are readily convertible to a known amount 
of cash and are subject to an insignificant risk of changes in value.

FINANCIAL  
STATEMENTS

Non-derivative financial liabilities
Non-derivative financial liabilities are stated at amortised cost using the 
effective interest method. The effective interest method is a method of 
calculating the amortised financial liability and of allocating interest over 
the relevant period. The effective interest rate is the rate that exactly 
discounts estimated future cash payments through the expected life of 
the financial liability, or, where appropriate, a shorter period, to the net 
carrying amount on initial recognition. For borrowings, their carrying value 
includes accrued interest payable, as well as unamortised issue costs.
Equity instruments
Equity instruments issued by the Company are recorded at the value of 
the proceeds received, net of direct transaction costs.
Derivative financial instruments and hedging
The Group’s activities expose it primarily to the financial risks of changes 
in foreign currency exchange rates and interest rates. The Group uses 
foreign exchange contracts and, on occasion, interest rate swap contracts 
to hedge these exposures. The use of financial derivatives is governed by 
the Group’s Treasury Policies as approved by the Board of Directors, 
which provides written principles on the use of derivatives. The Group 
does not use derivative financial instruments for speculative purposes.
Certain derivative instruments do not qualify for hedge accounting. These 
are categorised as fair value through profit or loss and are stated at fair 
value, with any resultant gain or loss recognised in the Income Statement.
The Group designates certain hedging instruments in respect of foreign 
currency risk as cash flow hedges. At the inception of the hedge 
relationship, the Group documents the relationship between the hedging 
instrument and the hedged item, along with its risk management 
objectives and strategy for undertaking various hedging transactions. 
The Group also documents, both at hedge inception and on an ongoing 
basis, whether the hedging instrument that is used in a hedging 
relationship is highly effective in offsetting changes in fair values 
or cash flows of the hedged item.
For the Group’s cash flow hedges of highly probable forecast transactions 
in foreign currencies, the hedged risk is always considered to be 1:1. 
If the underlying exposure changes over time, either due to commercial 
factors or timing differences, the hedging instruments will be rebalanced 
to ensure that the hedge ratio of 1:1 is maintained.
Changes in the fair value of derivative financial instruments that are 
designated and are effective as a cash flow hedge are recognised directly 
in equity and the ineffective portion is recognised immediately in the 
Consolidated Income Statement. If the cash flow hedge of a firm 
commitment or forecasted transaction results in the recognition of an asset 
or a liability, then, at the time the asset or liability is recognised, the 
associated gains or losses on the derivative that had previously been 
recognised in equity are included in the initial measurement of the asset or 
liability. For hedges that do not result in the recognition of an asset or a 
liability, amounts deferred in equity are recognised in the Income Statement 
in the same period in which the hedged item affects profit or loss.
For an effective hedge of an exposure to changes in fair value, the hedged 
item is adjusted for changes in fair value attributable to the risk being 
hedged with the corresponding entry in the Consolidated Income 
Statement. Gains or losses from re-measuring the derivative are also 
recognised in the Consolidated Income Statement. If the hedge is 
effective, these entries will offset in the Consolidated Income Statement.
Changes in the fair value of derivative financial instruments that do not 
qualify for hedge accounting are recognised in the Consolidated Income 
Statement as they arise.
Hedge accounting is discontinued when the hedging instrument expires 
or is sold, terminated, exercised, or no longer qualifies for hedge 
accounting. At that time, any cumulative gain or loss on the hedging 
instrument recognised in equity is retained in equity until the forecasted 
transaction occurs. If a hedged transaction is no longer expected to occur, 
the net cumulative gain or loss recognised in Equity is transferred to the 
Consolidated Income Statement for the period.
Gains and losses accumulated in Equity are recognised in the 
Consolidated Income Statement on disposal of the overseas business.
Assets and disposal groups held for sale
Assets are classified as held for sale if their carrying amount will be 
recovered by sale rather than by continuing use in the business. Where 
a group of assets and their directly associated liabilities are to be disposed 
of in a single transaction, such disposal groups are also classified as held 
for sale. For this to be the case, the asset or disposal group must be 
available for immediate sale in its present condition, and Directors must 
be committed to and have initiated a plan to sell the asset or disposal 
group which, when initiated, was expected to result in a completed sale 
within 12 months. Assets that are classified as held for sale are not 
depreciated. Assets or disposal groups that are classified as held for sale 
are measured at the lower of their carrying amount and fair value less 
costs to sell.
Provisions
Provisions are recognised when the Group has a present obligation (legal 
or constructive) as a result of a past event, it is probable that the Group 
will be required to settle that obligation and a reliable estimate can be 
made of the amount of the obligation. Provisions are measured at the 
Directors’ best estimate of the expenditure required to settle the 
obligation at the Balance Sheet date, taking into account the risks 
and uncertainties (such as timing or amount) surrounding the obligation. 
They are not discounted to present value if the effect is not material.
Provisions for restructuring are recognised when the Group has a detailed 
formal plan for the restructuring and the plan has been communicated to 
the affected parties. Provisions for the expected cost for warranty 
obligations under local sale of goods legislation are recognised at the date 
of sale of the relevant products.
Share-based payments
The Group applies the requirements of IFRS 2 Share-based payments.
The Group issues equity-settled share-based payments to certain 
employees. The fair value (excluding the effect of non-market-related 
conditions), as determined at the grant date, is expensed on a straight-line 
basis over the vesting period, based on the Group’s estimate of the 
number of shares that will eventually vest and adjusted for the effect of 
non-market-related conditions.
Fair value is measured by use of a Black-Scholes model for the share 
option plans, and a binomial model for the share awards under the 2014 
Long-Term Incentive Plan.
The liability in respect of equity-settled amounts is included in Equity.
Critical accounting judgments
IAS 1 requires disclosure of the judgments Management makes when 
applying its significant accounting policies and that have the most 
significant effect on amounts that are recognised in the Group’s Financial 
Statements. In the course of preparing the Financial Statements, no 
significant critical judgments have been made in the process of applying 
the Group’s accounting policies, other than held for sale, leases and those 
involving estimations, which are dealt with separately below. 
Management makes other judgments in the normal course of conducting 
business, such as those in relation to legal claims and contractual matters 
(see Note 24 for further details).

ADDITIONAL  
INFORMATION

Held for sale
At 31 December 2024, Management makes a judgment to determine that 
the potential divestment of the Aerostructures business does not meet 
the held for sale criteria in accordance with IFRS 5. In particular, the 
potential divestment does not meet the threshold of highly probable, 
including not fully meeting the expectation that it would be completed 
within 12 months when assessed as at 31 December 2024 based on 
facts available and circumstances at that time. In making this judgment, 
the board considered the publicised challenges at Boeing, including 737 
MAX volumes being subdued throughout the year, following the Alaskan 
Airlines incident in January 2024 and the subsequent Boeing employee 
strike from September to November 2024. The Board also considered the 
risks and uncertainties set out on pages 50 to 59 which could impact the 
length of the potential divestment process, in particular the impact of 
geopolitical and economic uncertainties.
Leases
Where a lease includes the option for an extension to the lease term, 
Management makes a judgment as to whether they are reasonably 
certain the option will be taken. This will take into account the length of 
time remaining before the option is exercisable, current and forecasted 
plans for utilising the asset and the level and type of planned future capital 
investment. As at 31 December 2024, these extension options have an 
approximate average remaining lease term of 5 years. These judgments 
are reassessed at each reporting period or when there is a significant 
event affecting the lease, which could result in a recalculation of the lease 
liability and a material adjustment to the associated balances.
Key sources of estimation and uncertainty
When applying the Group’s accounting policies, Management must make 
assumptions and estimates concerning the future that affect the carrying 
amounts of assets and liabilities at the Balance Sheet date and the 
amounts of revenue and expenses recognised during the period. Such 
assumptions are based upon factors including historical experience, the 
observance of trends in the industries in which the Group operates, and 
information available from the Group’s customers and other external 
sources. The key sources of estimation and uncertainty at the Balance 
Sheet date that have a significant risk of causing a material adjustment to 
the carrying amounts of assets and liabilities within the next financial year 
and beyond include:
Retirement benefits
Management makes assumptions and estimates, for the next financial 
year and beyond, which affect the value of the carrying amount of the 
UK Plan retirement benefit obligation at 31 December 2024. 
Management follows actuarial advice from a third party when determining 
estimation uncertainty on the valuation of the UK gross defined benefit 
obligation, the significant assumptions being discount rate, inflation 
and life expectancy (see Note 33). The carrying amount of the UK Plan’s 
retirement benefits at 31 December 2024 was a surplus of £43.5m 
(2023 – surplus of £48.5m), being the present value of the defined benefit 
obligations of £181.9m (2023 – £199.2m) and fair value of plan assets 
of £225.4m (2023 – £247.7m). Further details and sensitivities from 
changes in estimates are set out in Note 33g.
Warranty
The warranty costs include a provision of £11.8m (2023 – £11.0m) 
related to one specific disputed commercial matter. The range of 
reasonably possible outcomes considered by the Board is £6m, which 
reflects a reasonably possible increase of £4m or decrease of £2m. 
No further details on the matter are disclosed to avoid prejudicing the 
contractual position. 	
Other estimates
Income taxes, specifically in relation to provisions for tax uncertainties, 
have been removed as a key estimate in 2024 following the release in 
respect of historical Americas uncertain tax positions in 2023.
The Board previously approved a restructuring plan that was initiated in 
2019. In response to the pandemic, the Group implemented further cost 
cutting actions which included asset write downs. In 2023, some residual 
restructuring activity took place in response to further specific end market 
conditions affecting some of the businesses. In 2024, the restructuring 
provision is £nil and no longer represents a key estimate.
Consideration of climate change	
	
	
In preparing the Financial Statements, the Directors have considered the 
impact of climate change, particularly in the context of the risks identified 
in the TCFD disclosure on pages 20 to 25. There has been no material 
impact identified on the financial reporting judgments and estimates. 
In particular, the Directors considered the impact of climate change in 
respect of the following areas:
•	 Useful lives of assets – The useful lives of assets could be reduced by 
climate-related matters, for example as a result of physical risks, 
obsolescence or legal restrictions. The change in useful lives would 
have a direct impact on the amount of depreciation or amortisation 
recognised each year from the date of reassessment. The Directors’ 
review of useful lives has taken into consideration the impacts of the 
Group’s Net Zero commitments and has not had a material impact on 
the results for the year.
•	 Inventory valuation – Climate-related matters may affect the value of 
inventories as they could become obsolete as a result of a decline in 
selling price or a reduction in demand. After consideration of the typical 
inventory days compared to the rate of change in the market the 
Directors consider that inventory is appropriately valued.
•	 Going concern and viability – risks identified in the TCFD disclosures in 
pages 20 to 25 have been factored into the going concern and viability 
assessment. See page 68 further details.
•	 Goodwill impairment assessment – cash flow forecasts used in the 
impairment assessment of goodwill have considered potential changes 
in demand over the next 5 years as a result of changing customer 
preferences on Senior’s products. This is not expected to have a 
material impact on the cashflows, with longer-term growth rates based 
on forecasted market demand. Aerospace market rates were used for 
the Aerospace CGU and long-term GDP rates for advanced economies 
were used for the Flexonics CGU. Sensitivity analysis (See Note 13) 
shows that a 1 percent decrease in growth rate would not result in the 
carrying amount of CGU groups exceeding their recoverable amount.
•	 Recoverability of trade receivables – After consideration of the typical 
receivable days compared to the rate of change in the market, the 
Directors consider that receivables at 31 December 2024 are not 
adversely affected by climate change.
•	 Valuation of the UK Plan retirement gross benefit obligation – there is 
no material impact on key financial assumptions which are set 
according to market yields. Mortality assumptions take account of 
current views of possible climate pathways that may develop. Asset 
values are set according to market valuations which incorporate market 
expectations of climate impacts.
The Directors are aware of the ever-changing risks attached to climate 
change and will regularly assess these risks against judgments and 
estimates made in preparation of the Group’s Financial Statements.

4. Segment information
The Group reports its segment information as two operating Divisions 
according to the market segments they serve, Aerospace and Flexonics, 
which is consistent with the oversight employed by the Executive 
Committee. The chief operating decision-maker, as defined by IFRS 8, 
is the Executive Committee. The Group is managed on the same basis, 
as two operating Divisions.
The accounting policies of the reportable segments are the same as the 
Group’s accounting policies described in Note 2 and the sales between 
segments are carried out at arm’s length. Adjusted operating profit, 
as described in Note 9, is the key measure reported to the Group’s 
Executive Committee for the purpose of resource allocation and 
assessment of segment performance. Finance income, finance costs 
and tax are not allocated to segments, as this type of activity is driven 
by the central tax and treasury functions.
Segment assets include directly attributable computer software assets, 
property, plant and equipment (including right-of-use assets), working 
capital assets, goodwill and intangible assets from acquisitions. Cash, 
deferred and current tax and other financial assets (except for working 
capital) are not allocated to segments for the purposes of reporting 
financial performance to the Executive Committee.
Segment liabilities include directly attributable working capital liabilities 
and lease liabilities. Debt, retirement benefits, deferred and current tax 
and other financial liabilities (except for working capital) are not allocated 
to segments for the purposes of reporting financial performance to the 
Executive Committee.
Central costs, assets and liabilities are corporate items not allocated 
to segments, which is consistent with the format used by the chief 
operating decision-maker.

Fees payable to the Company’s Auditor and their associates for non-audit services to the Company are not required to be disclosed because the 
Consolidated Financial Statements are required to disclose such fees on a consolidated basis.
The Group paid £0.08m (2023 – £0.06m) to the Company’s Auditor for audit related services and £nil (2023 – £nil) for non-audit-related services during 
2024, in line with the Company’s policy on the use of Auditors for non-audit services.
Details of the Company’s policy on the use of auditors for non-audit services, the reasons why the Auditor was used rather than another supplier and 
how the Auditor’s independence and objectivity were safeguarded are set out in the Audit Committee Report on pages 90 to 95. No services were

9. Adjusted operating profit and adjusted profit before tax
The presentation of adjusted operating profit and adjusted profit before tax measures, derived in accordance with the table below, has been included 
to identify the performance of the Group prior to the impact of amortisation of intangible assets from acquisitions, net restructuring costs, site 
relocation costs, US class action lawsuit and costs associated with corporate undertakings. The Board has a policy, which was clarified in 2023, 
to separately disclose items it considers are outside the normal course of management oversight and control on a day-to-day basis and are not 
reflective of in-year trading performance. Indicative criteria such as period to which the item relates and external driven factors that are outside 
of the control of the Group in combination with the magnitude and consistency of application are also considered.
The amortisation charge relates to the acquisition of Spencer Aerospace. It is charged on a straight-line basis and reflects a non-cash item for the 
reported year. Site relocation costs relate to transfer of business activities into new or existing cost competitive facilities to support the Group’s 
strategic initiatives. The US class action lawsuit relates to an historic legal matter. The Group implemented a restructuring programme in 2019, which 
had residual activity in 2023 in response to further specific end market conditions. Corporate undertakings relate to business acquisition and disposal 
activities. None of these charges are reflective of in-year performance. Therefore, they are excluded by the Board and Executive Committee when 
measuring the operating performance of the businesses.

Site relocation costs
In 2024, £3.5m of site relocation costs were incurred (2023 – £0.1m) of which £0.5m (2023 – £0.1m) related to the transfer of our Senior Flexonics 
Crumlin business to a nearby high-tech facility in Wales to better showcase its design, development, test and qualification capabilities in support of 
the Group’s strategic initiatives. The Group also recognised an impairment of £1.9m of property, plant and equipment and costs of £1.1m related to the 
transfer of existing business to other cost competitive facilities.
US class action lawsuit
In June 2022, a wage and hour class action lawsuit was filed against one business based in California, USA. This lawsuit alleged violations of state 
regulations concerning meal and rest breaks and related penalties covering the period 2021 through the first half of 2024. Mediation took place in 
April 2024, resulting in a Company agreed settlement and related costs of £1.1m, of which no payments have been made as at 31 December 2024. 
Court approval and payment is expected by the end of the first half of 2025.
Net restructuring costs
In 2024, no restructuring costs were incurred in the Consolidated Income Statement. In 2023, £5.6m was incurred, of which £2.4m related to 
consultancy and other costs, £2.0m related to inventory impairment where customer demand had decreased and £1.2m related to impairment 
of property, plant and equipment to cover the risk where there were no alternative uses.
Net restructuring cash outflow was £0.5m (2023 – £2.1m).
Corporate undertakings
Net income associated with corporate undertakings was £1.0m (2023 – £7.6m costs), of which £0.8m acquisition costs (2023 – £1.5m) and £2.2m 
income from fair value changes in contingent consideration (2023 – £2.9m costs) related to the acquisition of Spencer Aerospace in November 2022 
and £0.4m costs are associated with potential disposal and other corporate activities (2023 – £3.2m). See Note 30 to the Financial Statements for 
further details on the financial impact of the acquisition in 2024.

On 24th May 2021, a future increase in UK corporation tax rate from 19% to 25% was substantially enacted with an effective date of 1 April 2023. 
Deferred tax assets and liabilities are measured at the rates that are expected to apply to the year when the asset is realised or the liability is settled, 
based on tax rates (and tax laws) that have been enacted or substantially enacted at the Balance Sheet date. Taxation for other jurisdictions is 
calculated at the rates prevailing in the respective jurisdictions.
In the prior year, the Group implemented a series of steps to simplify the legal ownership of its Americas legal entity holding structure. As part of the 
exercise, provisions held for estimated uncertain tax positions around the historical establishment of the Americas legal structure were reassessed. 
As a result, in accordance with IAS 12 and IFRIC 23 (Uncertainty over Income Tax Treatments), provisions for the uncertain tax positions of £7.0m 
and associated interest of £3.5m were released to the Consolidated Income Statement during that year.
The OECD Pillar Two Globe Rules introduce a global minimum corporate tax rate, initially at 15%, applicable to multinational enterprise (MNE) groups 
with global revenue over €750m. All participating OECD members are required to incorporate these rules into national legislation. On 20th June 2023, 
the UK substantially enacted legislation to apply Pillar Two Globe rules into UK law which will first apply to the Group from 1 January 2024. The Group 
has provided £0.1m in the current year in respect of this liability.

Goodwill is allocated to the group of CGUs (CGU groups) namely Aerospace and Flexonics, reflecting the lowest level at which management exercises 
oversight and monitors the Group’s performance. Central assets are allocated between the CGU groups on the basis of the percentage share of 
trading assets. The table below highlights the carrying amount of goodwill allocated to these CGU groups, all of which are considered significant in

ADDITIONAL  
INFORMATION

The Group tests goodwill annually for impairment or more frequently if there are indications that goodwill might be impaired. The timing of the annual 
assessment at 30 September 2024 coincided with the Board’s review of the most recent financial strategy. Management applied the value in use 
methodology to assess impairment. The key assumptions on which the value in use calculations were based relate to business performance over the 
next five years, long-term growth rates beyond 2029 and the discount rates applied. The discount rates were pre-tax measures based on the rate of 
10-year government bonds issued in the relevant market and in the same currency as the cash flows, adjusted for a risk premium to reflect both the 
increased risk of investing in equities generally and the systematic risk of the CGU group. The key estimates were the level of revenue and operating 
margins anticipated and the proportion of operating profit converted into cash flow in each year, long-term growth rates and discount rates applied. 
The forecast compound annual growth rate in revenue from 2024 to 2029 was 8% (2023 – 2023 to 2028 was 8%), reflecting expected increases in 
aircraft production as communicated by our customers and secured new programmes in Flexonics.
Forecasts used in the cash flow were based on the most recent financial strategy, as approved by Management for the next five years to 2029. 
These estimates up to 2029, where appropriate, take account of the current economic environment as set out in the Strategic Report on pages 1 to 69.
Cash flows after 2029 have been extrapolated based on estimated long-term growth rates into perpetuity, which has been determined by the lower 
of the long-term market growth rates and the historical forecast compound annual growth in revenue to 2029. For Aerospace, the long-term market 
growth rate is 4.2% per annum (2023 – 3.8%), which does not exceed the long-term average growth rate forecast for the aerospace market as 
included in market outlooks from Boeing and Airbus. For Flexonics, the long-term market growth rate is 1.6% per annum (2023 – 1.6%), which is 
based on the world long-term forecast GDP growth for advanced economies.
The pre-tax discount rates applied to discount the pre-tax cash flows for Aerospace and Flexonics are 10.4% and 10.8% respectively (2023 – 11.6% 
and 12.3%); these discount rates include CGU group specific risk adjustments which are the measurements used by Management in assessing 
investment appraisals specific to each CGU group.
Sensitivities reflecting reasonable possible changes have also been considered for each CGU group in relation to the value in use calculations. 
Each assumption was sensitised in isolation: Revenue was reduced by 10 percentage points in the terminal value, operating margins were reduced by 
1 percentage point in the terminal value, the proportion of operating profit converted into cash flow was reduced by 5 percentage points in the terminal 
value, the long-term growth rate assumption was reduced by 1 percentage point and the discount rate was increased by 1 percentage point. This did 
not result in the carrying amount of the CGU groups exceeding their recoverable amount.
Further to the 30 September 2024 annual impairment test, the Board considered whether there were any triggering events as at the 31 December 2024 
reporting date. Despite the near-term temporary headwinds announced in October 2024, the Board concluded that these events did not trigger an 
impairment assessment as at 31 December 2024 given the long-term growth prospects which underpin the recoverable amount of each CGU group.

In 2024, £1.9m right-of-use assets were impaired (2023 – £1.2m property, plant and equipment; see note 9). The recoverable amount of the assets 
was determined based on value-in-use for assets with confirmed orders, or fair value less costs to sell, where assets are to be disposed.
At 31 December 2024, the Group had entered into contractual commitments for the acquisition of property, plant and equipment amounting to £6.5m 
(2023 – £4.0m).

Credit risk
The Group’s principal financial assets are bank balances and cash and trade receivables. The credit risk on liquid funds and derivative financial 
instruments is limited because the counterparties are banks with high credit ratings assigned by international credit rating agencies.
The Group’s credit risk is primarily attributable to its trade receivables. The amounts presented in the Consolidated Balance Sheet are net of loss 
allowances. There are no other credit or impairment losses for other classes of financial assets.
Further disclosures on credit risk are included in Note 20.
The average credit period taken on sales of goods is 56 days (2023 – 58 days). An allowance has been made for estimated irrecoverable amounts from 
the sale of goods of £3.5m (2023 – £2.3m). In determining the recoverability of trade receivables, the Group considers any change in the credit quality 
of the trade receivable from the date credit was initially granted up to the reporting date. At 31 December 2024, the carrying amount of the receivable 
from the Group’s most significant customer was £6.5m (2023 – £6.7m from the same customer). The Group has no other significant concentration of 
credit risk, with exposure spread over a large number of counterparties and customers. Accordingly, the Directors believe that there is no further credit 
provision risk in excess of the loss allowance.

Bank loans and overdrafts of £37.9m (2023 – £58.8m) are arranged at floating rates, thus exposing the Group to cash flow interest rate risk. Other 
borrowings are mainly arranged at fixed interest rates and expose the Group to fair value interest rate risk. No interest rate swaps were taken out in 
2023 or 2024.
The Directors estimate the fair value of the Group’s borrowings to be as follows:

The fair value of Other loans has been determined by applying a make-whole calculation using the prevailing treasury bill yields plus the applicable 
credit spread for the Group (level 2 of the fair value hierarchy as defined in Note 20).
The other principal features of the Group’s borrowings are as follows:
Bank overdrafts are repayable on demand. The effective interest rates on bank overdrafts are determined based on SONIA, SOFR and appropriate 
LIBOR rates plus applicable margins.
The Group’s main loans are unsecured guaranteed loan notes in the US private placement market and revolving credit facilities. 
a)	Loan notes of €28m, 2024 £23.1m (2023 – £24.3m) were taken out in January 2017, carry interest at the rate of 1.51% and mature on 1 February 2027.
b)	Loan notes of $60m, 2024 £48.0m (2023 – £47.3m) were taken out in October 2015 and are due for repayment in October 2025. The loan notes 
carry interest at the rate of 3.75% per annum.
c)	Loan notes of £27m were drawn down in January 2018, carry interest at a rate of 2.35% and are due for repayment in January 2025.
d)	Loan notes of $30m, 2024 £24.0m (2023 – £23.6m) were taken out in September 2018, carry interest at the rate of 4.18% and are due 
for repayment in September 2028.
e)	Loan notes of $50m, 2024 £40.0m (2023 – £nil) were taken out in February 2024, carry an interest rate of 6.26% and are due for repayment 
in February 2030.
Transaction costs of £0.2m, directly attributable to the US Dollar notes (£0.2m), have been deducted from their carrying value.
New private placement notes of $40m (£32m) were issued in February 2025. The loan notes were also drawn down in February 2025, 
carry an interest rate of 5.46% and are due for repayment in February 2029.
The Group also has two revolving credit facilities.

A committed multi-currency revolving credit facility in the UK of £115m (2023 – £115m) matures in November 2027. At 31 December 2024, £28.4m 
was outstanding under the £115m facility, comprising $8.0m (£6.4m) and £22.0m. At 31 December 2023, £53.2m was outstanding under the £115m 
facility, comprising $46.0m (£36.2m) and £17.0m.
A committed $50m (£40.0m) single bank loans and letter of credit facility matures in June 2026. There were $11.9m (£9.5m) loans with reference 
to Term SOFR which are drawn under the facility on 31 December 2024 and $4.9m (£3.8m) loans drawn in 31 December 2023 and there were letters 
of outstanding credit of $6.4m (£5.2m) (2023 – £2.2m).
As at 31 December 2024, the Group had available £111.9m (2023 – £95.1m) of undrawn committed borrowing facilities in respect of which all 
conditions precedent had been met. The weighted average maturity of the Group’s committed facilities at 31 December is 2.5 years (2023 – 2.9 years). 
The current weighted average maturity of the Group’s facilities, updated for the February 2025 loan notes of $40m, remains at 2.5 years.
20. Financial instruments
Capital risk management
The Group manages its capital structure to safeguard its ability to continue as a going concern whilst maximising the return to stakeholders through 
the optimisation of the balance between debt and equity. In considering the appropriate level of net debt, the Group pays close attention to its level 
as compared to the cash generation potential of the Group, measured by EBITDA (defined in the Notes to the Financial Headlines). The Group also 
monitors capital on the basis of a gearing ratio. This ratio is calculated as net debt divided by total capital. Net debt is derived in Note 31c. Lease 
liabilities are excluded from net debt in calculating the gearing ratio. Total capital is the equity shown in the Consolidated Balance Sheet.
The Group’s strategy in respect of gearing is to target a long-term gearing ratio within the range of 30% to 60%. The gearing ratio for the Group at the 
end of 2024 was 33% (2023 – 29%).
All of the Group’s external borrowing facilities at 31 December 2024 have a requirement for the ratio of net debt to EBITDA to be less than 3.0x 
(US Private Placements) or 3.5x (UK RCF and US RCF). IFRS 16 does not impact the Group’s lending covenants as these are currently based on frozen 
GAAP, hence figures quoted below exclude the impact of IFRS 16 on net debt, interest and EBITDA. As required by the covenant definition, net debt 
is restated using 12-month average exchange rates (consistent with EBITDA definition).
The Group has two covenants for committed borrowing facilities, which are tested at June and December: the Group’s net debt to EBITDA 
(defined in the Notes to the Financial Headlines) must not exceed 3.0x and interest cover, the ratio of EBITDA to interest must be higher than 3.5x. 
At 31 December 2024, the Group’s net debt to EBITDA was 1.8x (31 December 2023 – 1.6x) and interest cover was 7.0x (31 December 2023 – 12.6x), 
both comfortably within the covenants limits. 
Financial risk management
The Group’s activities expose it to a variety of financial risks including foreign exchange risk, interest rate risk, credit risk and liquidity risk. The Group’s 
overall treasury risk management programme focuses on the unpredictability of financial markets, and seeks to minimise potential adverse effects on 
the Group’s financial performance.
The Group uses derivative financial instruments to hedge certain risk exposures. The use of financial derivatives is governed by the Group’s policies 
approved by the Board, which provide written principles on foreign exchange risk, interest rate risk, credit risk, the use of financial derivatives and 
non-derivative financial instruments, and the investment of excess liquidity. Compliance with policies and exposure limits is reviewed by the Group’s 
Treasury Committee on a regular basis. The Group does not enter into or trade financial instruments, including derivative financial instruments, for 
speculative purposes.
Foreign exchange risk management
The Group enters into forward foreign exchange contracts to hedge the exchange risk arising on the operations’ trading activities in foreign currencies. 
Where commented on below, the sensitivity analysis of the Group’s exposure to foreign currency risk at the reporting date has been determined based 
on the change taking place at the beginning of the financial year and left unchanged throughout the reporting period, with all other variables held 
constant (such as interest rates). The sensitivity assumptions are based on analysis reviewed by the Group’s Treasury Committee.
Translation risk
The Group derived 83% of its revenue from businesses outside the United Kingdom, with 58% relating to operations in North America. Fluctuations 
in the value of the US Dollar and other currencies in relation to Pound Sterling have had, and may continue to have, a significant impact on the results 
of the Group’s operations when reported in Pound Sterling. The Group decided not to hedge this translation risk. In addition, the majority of assets 
are denominated in foreign currency, particularly in US Dollars. In order to provide a hedge against volatility in the value of these assets compared 
to the Group’s loss/earnings, and hence provide a natural hedge against the Group’s principal lending covenant (the ratio of net debt to EBITDA), 
the Group aims to borrow in foreign currencies in similar proportions to its generation of foreign currency EBITDA, where practical and economic. 
A 10% appreciation (or depreciation) of all other currencies against the Pound Sterling would have increased (or decreased) 2024 Group adjusted 
operating profit by £5.3m (£2.7m of which would have been due to the US Dollar movement) and would have increased (or decreased) equity by 
£34.7m (£22.4m of which would have been due to the US Dollar movement).

Transaction risk
The Group has a number of transaction-related foreign currency exposures, particularly between the US Dollar and the Pound Sterling, Thai Baht and 
Malaysian Ringgit. The Group seeks to hedge between 0% to 100% of transaction-related exposures mainly on a rolling 15 to 18-month forward basis, 
but in some cases for periods of up to 60 months and applies hedge accounting where the forwards can be designated in a qualifying cash flow hedge 
relationship. Based on the net of the annual sales and purchase-related exposures, all transaction-related foreign currency exposures to Group profit 
after hedging in existence at 31 December 2024 are immaterial. The impact on equity is determined by the unrecognised portion of open forward 
contracts at the year-end. A 10% appreciation (or depreciation) of the US Dollar against the Pound Sterling, Thai Baht and the Malaysian Ringgit would 
have decreased (or increased) equity by £4.5m, £1.6m and £0.5m, respectively.
Interest rate risk management
The Group has a policy of maintaining approximately 60% of its borrowing costs at fixed interest rates. The Group generally borrows long-term in fixed 
rates but at times may borrow at floating rates and swap into fixed depending on credit market conditions. Occasionally a portion of fixed debt interest 
is swapped into floating rates. The combination of maintaining an acceptable balance of fixed and floating rate debt, and the Group’s policy of 
borrowing in foreign currency in proportion to its generation of foreign currency earnings, provides an effective hedge against the impact of interest 
rate and foreign currency volatility on total interest costs. As at year-end 2024, the percentage of debt at fixed interest was 81% (2023 – 68%), 
excluding IFRS 16 lease liabilities from debt.
The following sensitivity analysis of the Group’s exposure to interest rate risk in 2024 has been retrospectively determined based on the exposure 
to applicable interest rates on financial assets and liabilities held throughout the financial year, with all other variables held constant (such as foreign 
exchange rates). The sensitivity assumptions are based on analysis reviewed by the Group’s Treasury Committee. If variable interest rates had been 
0.5% lower (or higher), the Group’s profit before tax would have increased (or decreased) by £0.4m. Any fixed interest debt is held to maturity and not 
fair value adjusted through the Consolidated Income Statement. An increase (or decrease) of 0.5% in the market interest rate for the fixed rate debt 
held up to maturity would have decreased (or increased) the fair value of the Group’s borrowings by £1.6m. The Group’s sensitivity to interest rates 
has remained broadly consistent with prior period due to the high proportion of fixed debt.
Credit risk management
The Group’s credit risk is primarily attributable to its trade receivables. The credit quality of customers is assessed taking into account their financial 
position, past experience and other factors. Further details on determining the recoverability of trade receivables is provided in Note 18. The Group is 
guarantor under one lease of a current subsidiary entity in the UK. Credit risk on liquid funds and derivative financial instruments is limited because the 
counterparties are financial institutions with high credit ratings assigned by international credit rating agencies. The carrying amount of financial assets 
recorded in the Financial Statements, which is net of impairment losses, represents the Group’s maximum exposure to credit risk. 
The Group participates in some non-recourse reverse factoring schemes which are arranged by customers. These are a form of non-recourse factoring 
that are common practice within the aerospace sector and with large customers in the Flexonics Division. In a reverse factoring scheme, a financial 
counterparty commits to pay supplier invoices ahead of due date in exchange for a discount interest charge. It is a funding solution initiated by the 
customer to provide the supplier with an alternative financing arrangement. The Group participates in reverse factoring schemes as a way of reducing 
credit risk. The trade receivables reverse factored at 31 December 2024 were £29.1m (2023 – £29.1m). The net impact of reverse factoring on 2024 
was a cash inflow in working capital of £nil (2023 – £5.5m inflow) and the discount interest presented within other finance costs is a charge of £0.9m 
in 2024 (2023 – £0.8m).
Liquidity risk management
Liquidity risk reflects the risk that the Group will have insufficient resources to meet its financial liabilities as they fall due. The Group manages liquidity 
risk by maintaining adequate reserves, banking facilities and revolving credit facilities, by continuously monitoring forecast and actual cash flows and 
matching the maturity profiles of financial assets and liabilities. Cash flow forecasts are produced monthly, together with appropriate capacity planning 
and scenario analysis, to ensure that bank covenant and liquidity targets will be met. The Directors also regularly assess the balance of capital and debt 
funding of the Group, as part of a process to satisfy the Group’s long-term strategic funding requirements.
As noted in the Financial Review on pages 64 to 67, the Group is currently in a well-funded position, with significant headroom under its committed 
borrowing facilities. It is considered unlikely that the Group will face any significant funding issues in the foreseeable future.

These fair values are based on market values of equivalent instruments at the Balance Sheet date, comprising £1.2m (2023 – £2.6m) assets included

designated and effective as cash flow hedges amounting to £4.2m loss (2023 – £1.3m loss) has been deferred in equity.
Fair values
The following table presents an analysis of financial instruments that are measured subsequent to initial recognition at fair value, grouped into Levels 
1–3 based on the degree to which the fair value is observable:
Level 1	
those fair values derived from quoted prices (unadjusted) in active markets for identical assets or liabilities;	
	
	
Level 2	
those fair values derived from inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either 
directly (i.e. as prices) or indirectly (i.e. derived from prices); and
Level 3	
those fair values derived from valuation techniques that include inputs for the asset or liability that are not based on observable market data 
(unobservable inputs).
There has not been any transfer of assets or liabilities between levels. There are no non-recurring fair value measurements. Level 2 fair values are 
derived from future cash flows, of open forward contracts at 31 December, translated by the difference between contractual rates and observable 
forward exchange rates.

An amount of £0.1m loss (2023 – £0.7m gain) has been transferred to the Consolidated Income Statement, and is included within operating profit.
Hedge effectiveness is determined at the inception of the hedge relationship, and through periodic prospective effectiveness assessments to ensure 
that an economic relationship exists between the hedged item and hedging instrument. The Group enters into hedge relationships where the critical 
terms of the hedging instrument match exactly with the terms of the hedged item, and so a qualitative assessment of effectiveness is performed. 
If changes in circumstances affect the terms of the hedged item such that the critical terms no longer match exactly with the critical terms of the 
hedging instrument, the Group uses the hypothetical derivative method to assess effectiveness.
Ineffectiveness is recognised on a cash flow hedge where the cumulative change in the designated component value of the hedging instrument 
exceeds on an absolute basis the change in value of the hedged item attributable to the hedged risk. In hedges of the above foreign exchange 
contracts this may arise if the timing of the transaction changes from what was originally estimated.
The hedged forecast transactions denominated in foreign currency are expected to occur at various dates during the next 60 months. Amounts 
deferred in equity are recognised in the Consolidated Income Statement in the same period in which the hedged items affect profit or loss, 
which is generally within 12 months from the Balance Sheet date.
In 2023 and 2024, some cash flow hedging relationships were discontinued because forecast foreign currency transactions were no longer highly 
probable and no longer expected to occur. Previously accumulated gains or losses on the forward contracts were immediately reclassified to the 
income statement. These forward contracts, and the forward contracts entered to unwind the position, that remained at 31 December 2023 
and 31 December 2024 were presented in the Balance Sheet as held for trading assets.	
The fair value of contingent consideration is based on the expected present value technique, using risk-adjusted discount rate to discount probability 
weighted cashflows.

21. Tax balance sheet
Current tax
The current tax receivable of £2.8m (2023 – £2.3m) includes excess tax paid to tax authorities that is expected to be recovered within 12 months by 
way of offset against future tax liabilities or refund.
The majority of the Group’s taxable profits arise in countries, including the US, where the estimated tax liabilities are paid in on-account instalments 
during the year to which they relate and are largely paid at the Balance Sheet date. The current tax liability of £8.0m (2023 – £10.0m) includes £1.9m 
(2023 – £2.3m) tax due on profits of the current and prior years as well as £6.1m (2023 – £7.7m) provisions for tax uncertainties that represent amounts 
expected to be paid but by their nature, there is uncertainty over timing and eventual settlement.
The Group recognises provisions for tax items which are considered to have a range of possible tax outcomes and separately accounts for interest that 
may be due thereon. These uncertainties exist due to a number of factors including differing interpretations of local tax laws and the determination of 
appropriate arm’s length pricing in accordance with OECD transfer pricing principles on internal transactions and financing arrangements. In calculating 
the carrying amount of provisions, Management estimates the tax which could become payable as a result of differing interpretations and decisions by 
tax authorities in respect of transactions and events whose treatment for tax purposes is uncertain. In accordance with IFRIC 23, individual provisions 
are established based on an assessment of whether it is the most likely individual outcome, or the expected outcome on a probability basis that is 
likely to best reflect the resolution of the uncertainty. The range of reasonably possible outcomes considered by the Board is not expected to increase 
the provision by a material amount.

STATEMENTS

NOTES TO THE CONSOLIDATED 
FINANCIAL STATEMENTS CONTINUED
Deferred tax assets are recognised to the extent that it is probable that future taxable profits will be available, including those arising from the reversal 
of other taxable temporary differences, against which the assets can be utilised.
At the Balance Sheet date the Group has recognised deferred tax assets in respect of losses of £4.4m (2023 – £3.4m), including £0.4m (2023 – 
£1.6m) recognised against deferred tax liabilities and £4.0m (2023 – £1.8m) recognised based on anticipated profits in the Group’s five year forecast 
to 2029 as approved by the Board.
Due to uncertainty as to the availability of future profits against which tax losses may be utilised, £11.7m (2023 – £23.1m) of losses have not been 
recognised at the Balance Sheet date, following the recognition of £8.9m of losses in the year. Included in unrecognised tax losses are losses of 
£11.4m (2023 – £13.2m) that will expire over a period of one to nine years. Other losses may be carried forward indefinitely. 
At the Balance Sheet date, a deferred tax liability of £0.4m (2023 – £0.3m) has been recognised in respect of the aggregate amount of temporary 
differences associated with undistributed earnings of subsidiaries expected to reverse in the foreseeable future. No temporary difference has been 
recognised in respect of £30.7m (2023 – £28.0m) of undistributed earnings, which may be subject to a withholding tax, as the Group is in a position 
to control the timing of the reversal of the temporary differences and it is not probable that such differences will reverse in the foreseeable future.
The Group has determined that the global minimum Top up Tax, which it is required to pay under Pillar II legislation, is an income tax in the scope of 
IAS 12. The Group has applied a temporary mandatory relief from deferred tax accounting for the impacts of the Top up Tax and accounts for it as a 
current tax when it is incurred.
At the Balance Sheet date, the Group had £5.0m (2023 – £5.0m) of surplus Advanced Corporation Tax (‘ACT’), previously written off, for which no 
deferred tax asset has been recognised as it is unlikely to be recovered in the foreseeable future due to the UK earnings profile. The Group also has 
£18.0m (2023 – £18.0m) of unused capital losses.

Warranty
Provisions for warranty costs are based on an assessment of future claims with reference to past experience. Management exercises judgment 
to determine the best estimate of the most likely outcome for each provision separately. £4.8m of costs are expected to settle within the next 
12 months. The warranty costs include a provision of £11.8m (2023 – £11.0m) related to one specific disputed commercial matter. The range of 
reasonably possible outcomes considered by the Board is £6m, which reflects a reasonably possible increase of £4m or decrease of £2m. 
No further details on the matter are disclosed to avoid prejudicing the contractual position.
Legal claims and contractual matters
Provisions at 31 December 2024 comprise £6.7m (2023 – £7.1m) relating to contractual matters that have arisen in the ordinary course of business, 
the settlement of which are subject to ongoing discussions. Management exercises judgment to determine the best estimate of the most likely 
outcome, having considered each provision separately and the possible range of outcomes. Amounts are recorded for known issues based on past 
experience of similar items and other known factors and circumstances. As with any judgment there is a high degree of inherent uncertainty, 
particularly with legal proceedings and claims, and the actual amounts of the settlement could differ from the amount provided.

The Group uses foreign currency forward contracts to manage its foreign currency risk associated with its highly probable forecast transactions. These 
contracts are designated as cash flow hedge relationships. To the extent these hedges are effective, the change in fair value of the hedging instrument 
is recognised in the hedging reserve. The sum of the fair value of foreign exchange contracts deferred in the hedging reserve and recognised in the 
Income Statement is presented as foreign exchange contracts – cash flow hedges. See Note 20 for further details.

30. Acquisition and other corporate activities
Acquisition of Spencer Aerospace Manufacturing, LLC
On 25 November 2022, the Group acquired substantially all of the assets of Spencer Aerospace Manufacturing, LLC, a leading manufacturer of highly 
engineered, high-pressure hydraulic fluid fittings for use in commercial and military aerospace applications, located in Valencia, California, USA.
At 31 December 2024, there is a maximum contingent consideration remaining of $26.6m (£21.2m) potentially payable, in milestone amounts, 
dependent on the financial performance of Spencer Aerospace for the period from 1 January 2024 to 31 December 2026. The most likely range of this 
remaining contingent element is estimated between $21.6m and $26.6m. The fair value of $20.6m (£16.5m), which includes discounting, has been 
recognised at 31 December 2024. The fair value of contingent consideration assumes continuing to expand the relationship with Spencer’s established 
customers and leveraging Senior’s strong relationships with OEMs, Tier 1 integrators and after market customers around the world to exploit 
opportunities for Spencer Aerospace. In 2024, the fair value change relates to a release of £3.6m for the 2025 earnout target not expected to be 
payable as a result of the impact of the well publicised 737 MAX subdued volumes, partly offset by £1.4m interest unwind (2023 – £2.9m interest 
unwind). In 2023, $26.6m (£23.9m) deferred consideration net of working capital adjustment was paid.
In 2024, £0.8m costs (2023 – £1.5m) were incurred related to the acquisition.

settled share-based payments, and £0.3m (2023 – £0.6m) related to social security costs on share-based payments. As at 31 December 2024, 
the Group had a liability of £0.9m (2023 – £1.1m) arising from share-based payments relating to social security costs.
A) 2014 Long-Term Incentive Plan
Equity-settled Long-Term Incentive Plans
On 29 April 2024, 4,138,155 shares were awarded under the 2014 Long-Term Incentive Plan. Awards made under this plan have a three-year vesting 
period, and are subject to the following equally weighted performance conditions: adjusted earnings per share (EPS), total shareholder return (TSR), 
and for awards granted from 2021, there is also a return on capital employed (ROCE) performance condition. The adjusted EPS and ROCE 
performance conditions’ targets are expressed as absolute numbers for the final financial year of the three-year performance period. The threshold of 
the TSR performance condition requires the Company’s TSR performance to fall within the top half of a comparator group at the end of the three-year 
performance period. Vesting levels increase with higher performance. The awards are settled by delivering shares to the participants.
The estimated fair value for the awards granted in the year, excluding for the Executive Directors, with EPS and ROCE conditions is 164.40p, which is 
the share price at the date of grant. The estimated fair value for the awards granted in the year, excluding for the Executive Directors, with TSR 
conditions is 119.40p per share reflecting an adjustment of 33% to the fair value of the awards with EPS conditions due to the stringent TSR condition. 
The respective fair values for awards made to the Executive Directors is 141.1p and 102.7p reflecting the two-year retention period.
These fair values were calculated by applying a binomial option pricing model. This model incorporates a technique called “bootstrapping”, which 
models the impact of the TSR condition. The model inputs at the date of grant were the share price (164.40p for the main award), expected volatility 
of 46% per annum, and the performance conditions as noted above. Expected volatility was determined by calculating the historical volatility of the 
Group’s share price over the previous three years.

33. Retirement benefit schemes
The Group operates a number of pension plans in the UK, North America and Europe. These include both defined contribution arrangements and 
defined benefit arrangements. The Senior plc Pension Plan ("the UK Plan"), which is a funded scheme in the UK and closed to future accrual at the end 
of 6 April 2014, has the largest pension obligation in the Group and Company. This plan provides benefits based on final pensionable emoluments for 
the employees of the Group and Company. The latest full actuarial valuation was carried out as at 5 April 2022 and, for the purposes of accounting 
under IAS19, this valuation has been rolled forward to 31 December 2024.
In addition, the Group operates one defined benefit plan in the US, following settlement of a second plan in 2023. This plan was closed to future 
participants from September 2013, and the Executive section was also closed to future accruals from December 2013. 
Separate disclosure is made for the funded UK and US defined benefit arrangements. In both the UK and US, the assets of funded plans are held in 
separate trustee administered funds managed by independent financial institutions and have pension costs assessed by consulting actuaries using the 
Projected Unit Method. The Trustees are required to act in the best interests of the plans’ beneficiaries.
The Group also has a small number of unfunded post-retirement plans, including a closed healthcare scheme in the US. Separate disclosure is provided 
for these arrangements.
Further details on the arrangement of the UK Plan are given below.
The Trustee of the UK Plan is Senior Trustee Limited. The appointment of the Directors to the Board is determined by the Articles of Association 
of Senior Trustee Limited. There are seven Trustee Directors in total and in accordance with statutory requirements under the Pensions Act 2004, 
at least one-third of trustees must be a Member Nominated Director. Currently, there are three Member Nominated Directors and four Directors 
who have been nominated by the Company, of which the Chairman and one other Director are viewed as independent.
The UK Plan exposes the Company to a number of risks. In particular:
•	 Uncertainty in benefit payments – the value of the obligations will ultimately depend on the amount of benefits paid out. This in turn will depend 
on factors such as the level of inflation and how long individuals live.
•	 Volatility in asset values – the value of the assets held to meet future benefit payments is volatile, for example due to changes in stock markets 
and interest rates.
•	 Uncertainty in cash funding – movements in the value of the UK Plan’s obligations or assets may result in the Company being required to provide 
higher levels of cash funding.
The investment strategy for the UK Plan is decided by the Trustee in consultation with Senior plc. The primary investment objective is for the Plan to be 
able to meet benefit payments as they fall due. The UK Plan’s average duration is around 11 years and benefits are expected to be paid for the next 
60 years. These cash flow payments are expected to reach a peak around 2031, and gradually decline thereafter as the membership matures. In setting 
this strategy, the Trustee considers a wide range of asset classes, the risk and rewards of a number of possible asset allocation options, the sustainability 
of each asset class within each strategy, and the need for appropriate diversification between different asset classes. The Trustee’s current investment 
strategy is to invest 100% in lower risk assets, consisting of corporate bonds, liability driven investments (“LDI”), gilts and cash. The LDI allocation 
helps to mitigate investment risk for the UK Plan by minimising the fluctuations in the UK Plan’s funding levels arising from changes in the value of the 
liabilities. This is achieved through hedging movements in the funding liabilities caused by changes in interest rates and inflation expectations. 
The Trustee continues to review its investment strategy and adjust it in response to changes in the Plan’s funding position and/or market conditions.
The UK Plan was in a surplus position of £24.5m as at 5 April 2022 when measured on the Trustee's funding basis and is in a surplus position of 
£43.5m as at 31 December 2024 (31 December 2023 – £48.5m surplus) when measured on an IAS 19 basis. The difference between the triennial 
funding and annual IAS 19 valuation relates to the assumptions used. For example, the funding discount rate is based on the UK Plan’s stated 
investment strategy, as opposed to the yields available on corporate bonds for the IAS 19 discount rate.

FINANCIAL 
STATEMENTS

NOTES TO THE CONSOLIDATED 
FINANCIAL STATEMENTS CONTINUED
The IAS 19 surplus position on the UK Plan is recognised as an asset in the Consolidated and Company Balance Sheet, with no requirement to 
recognise an additional liability on the UK Plan, on the grounds that the Company has an unconditional right to a refund, assuming the gradual 
settlement of Plan liabilities over time until all members have left. In considering this, the Company has taken into account that the Trustees do not 
have unilateral powers to wind up the Plan or modify benefits.
Cash contributions to the UK Plan are set by agreement between the Company and the Trustee of the UK Plan. These are set in accordance with 
legislation and take account of the intention to further reduce the risk associated with the UK Plan’s investment strategy, as set out above. The 
contributions were last reviewed as at 5 April 2022 and were based on a forecast surplus at that time, as part of the 2022 triennial funding valuation. 
The Company agreed with the Trustee of the UK Plan to make scheduled contributions in respect of administrative expenses and PPF levies from 
5 April 2022 until 30 June 2022, with no further contributions after this date. The estimated contributions expected to be paid during 2025 in the 
US funded plans is £0.4m. 
The Group is ultimately responsible for making up any shortfall in the UK Plan over a period agreed with the Trustees. To the extent that actual 
experience is different from that assumed, the funding position will be better or worse than anticipated. As such, the contributions required by the 
Group could vary in the future. 
In June 2023, the High Court handed down a decision in the case of Virgin Media Limited v NTL Pension Trustees II Limited and others relating to 
the validity of certain historical pension changes due to the lack of actuarial confirmation required by law. In July 2024, the Court of Appeal dismissed 
the appeal brought by Virgin Media Ltd against aspects of the June 2023 decision. The Company and pension trustees are currently considering the 
implications of the case for the UK Plan. The defined benefit obligation has been calculated on the basis of the pension benefits currently being 
administered, and at this stage the Directors do not consider it necessary to make any adjustments as a result of the Virgin Media case.
a) Defined contribution schemes
The Group has a number of different defined contribution and government-sponsored arrangements in place in the countries in which it operates. 
None of these are individually material to the Group and the aggregate cost of such schemes for the period was £11.5m (2023 – £10.2m).
b) Defined benefit schemes
The amount included in the Consolidated Balance Sheet arising from the Group’s obligations in respect of its defined benefit plans is set out below.

The UK Plan’s assets are invested in pooled funds, which are invested exclusively within instruments with quoted market prices in an active market, 
with the exception of the Plan’s holdings in insurance annuity policies which are included in cash and net current assets, valued at £3.1m (2023 – £3.6m). 
The value of the invested assets has been measured at bid value and the value of the scheme benefits covered by the insurance annuity policies has 
been set equal to the value of the corresponding obligations.

STATEMENTS

NOTES TO THE CONSOLIDATED 
FINANCIAL STATEMENTS CONTINUED
The Plan’s corporate bond allocation is split between an actively managed mandate and a "buy and maintain" mandate, which seeks to hold a high quality 
portfolio while minimising portfolio turnover. Both mandates are predominantly invested in investment grade UK corporate bonds and are exposed to a 
fairly typical range of UK businesses. The majority of the Plan’s gilts are passively invested in a range of UK fixed-interest and index-linked government 
bonds, with the remainder actively invested in a range of swap instruments linked to movements in government bond prices. The risks associated with 
the Plan’s bond and gilt investments are largely offset by corresponding risks present within the pricing of the Plan’s benefit obligations.
The UK Plan does not invest directly in property occupied by the Company or in financial securities issued by the Company.

Benefits under the US funded plans are not linked to inflation.
The UK Plan retirement benefit obligation is discounted at a rate set by reference to market yields at the end of the reporting period on high quality 
corporate bonds. Estimation is required when setting the criteria for bonds to be included in the population from which the yield curve is derived. The 
most significant criteria considered for the selection of bonds include the issue size of the corporate bonds, quality of the bonds and the identification 
of outliers which are excluded. The assumption for estimating future Retail Price Index (RPI) inflation is based on the difference in yields on fixed-
interest and index-linked gilts. Demographic assumptions are set broadly in line with the most recent actuarial valuation of the UK plan. The mortality 
assumption is 95% of standard mortality tables with an allowance for future improvements in line with the CMI 2023 enhanced projections, with a 
long-term annual rate of improvement of 1.25% for males and for females, with no weighting on 2020 and 2021 mortality data and a 20% weighting 
on each of 2022 and 2023 mortality data to make an allowance for the longer term impact of Covid-19 and other factors.
For the UK Plan, the estimated impact on the plan surplus at 31 December 2024 for changes in assumptions is as follows:
Increase/
(decrease)
in plan surplus
£m
0.5% decrease in the discount rate
 (9.1)
One-year increase in life expectancy
 (7.5)
0.5% increase in inflation
 (5.4)
These sensitivities have been calculated to show the movement in the surplus, including allowance for an increase to the value of insured annuity 
assets, but assuming no other changes in assets as at 31 December 2024. This is unlikely in practice – for example, a change in discount rate is 
unlikely to occur without any movement in the value of the assets held by the Plan.
h) Other post-retirement liabilities
This balance comprises an unfunded German pension plan of £2.5m (2023 – £2.6m), unfunded closed pension and post-retirement healthcare plans in 
the US of £0.4m (2023 – £0.4m), a provision for post-retirement payments in France of £1.4m (2023 – £1.4m) and £1.1m for post-retirement payments 
in Thailand (2023 – £0.8m).
The closed pension and post-retirement healthcare plans in the US have been valued on a Projected Unit Method using a discount rate of 5.63% 
(2023 – 5.0%). No participants were eligible for medical benefits under the healthcare plan in 2024. The German plan has been subject to formal 
actuarial valuation on a Projected Unit Method with the following assumptions: discount rate 3.17%, salary growth nil% and pension increase 2.2% 
(2023 – 3.7%, nil% and 2.2%). In France, the provision arises from a legal obligation to make payments to retirees in the first two years post-
retirement. Hence, it is not subject to discounting to the same extent as the other longer-term post-retirement liabilities. The Thailand plan has been 
subject to a formal actuarial valuation on a Projected Unit Method with the following assumptions: discount rate 3.75%, inflation rate 3.0% and salary 
growth 6.0% (2023 – 3.75%, 3.0% and 6.0%).
34. Contingent liabilities
The Group is subject to various claims which arise from time to time in the course of its business including, for example, in relation to commercial 
matters, product quality or liability, and tax audits. Where the Board has assessed there to be a more likely than not outflow of economic benefits, 
provision has been made for the best estimate as at 31 December 2024 (see Note 24). For all other matters, the Board has concluded that it is not 
more likely than not that there will be an economic outflow of benefits. While the outcome of some of these matters cannot be predicted with any 
certainty, the Directors do not expect any of these arrangements, legal actions or claims, after allowing for provisions already made where appropriate, 
to result in significant loss to the Group.

Impairment provision at 31 December 2024 was £nil (2023 – £nil). Despite the near-term temporary headwinds announced in October 2024, the Board 
concluded that these events did not trigger an investment impairment assessment as at 31st December 2024 given the long-term growth prospects 
which underpin the recoverable amount of the investment held by the Company.

The Directors consider that the carrying amount of debtors approximates to their fair value. The maximum exposure to credit risk at the reporting date 
is the fair value of each class of receivable above. The Company does not hold any collateral as security.
The carrying amounts due from subsidiaries approximates to their fair value. There are no past due receivable balances and expected credit losses are 
immaterial (2023 – immaterial).
As at 31 December 2024, other receivables due in more than one year consist of £6.8m (2023 – £6.8m) due in accordance with the vesting periods 
of share-based payments and £87.1m (2023 – £24.4m) of loans to subsidiaries at market rates of interest, including £64.0m of loans due from 
subsidiaries that were re-evaluated as non-current following a review of when the Company expects the loans to be realised.

mainly arranged at fixed interest rates and expose the Company to fair value interest rate risk. No interest rate swaps were taken out in 2023 or 2024. 
Transaction costs of £1.0m (2023 – £1.1m) have been deducted from the bank loans carrying value. Transaction costs of £0.1m (2023 – £0.2m), directly

Share Registrars
All shareholder records are maintained by Equiniti and all correspondence should be addressed to the Registrars, Senior plc at the Equiniti address 
shown on the inside back cover, quoting the reference number starting with 0228 detailed on your dividend vouchers. The Registrars should be 
notified regarding changes to name or address, loss of share certificate, or request for, or change to, a dividend mandate.
Equiniti provides a range of shareholder information online. Shareholders can check their holdings, update details and obtain practical help on 
transferring shares at: www.shareview.co.uk.
Instead of payment by post to your registered address, dividends can be paid through the BACS system direct into a UK bank or building society 
account, with the dividend voucher still sent to your registered address. If you wish to use this facility and have not previously applied, then please 
apply direct to Equiniti and request a dividend mandate form. Shareholders who are currently receiving duplicate sets of Company mailings, 
as a result of any inconsistency in name or address details, should write direct to Equiniti so holdings can be combined, if appropriate.
CREST Proxy Voting
CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service may do so for the Annual General 
Meeting to be held on 25 April 2025 and any adjournment(s) thereof by using the procedures described in the CREST manual. Further details relating 
to voting via CREST may be found on the 2025 AGM Notice of Meeting and Form of Proxy.
