Statement of Executive Chair
Science Group plc is an international science & technology 
consultancy and systems organisation. In 2024, Science Group 
again demonstrated the resilience of its operating model and, in 
an unpredictable economic and political environment, the Group 
has delivered another year of record profitability.
In early 2025, the Group’s robust balance sheet, accumulated cash 
resources and strong operating cash flow enabled Science Group 
to make an investment in Ricardo plc (‘Ricardo’), a UK-based, 
science and technology consultancy and engineering business. 
Science Group is now the second largest shareholder in Ricardo.
Financial Summary
For the year ended 31 December 2024, Science Group reported 
adjusted operating profit of £21.5 million (2023: £20.5 million) 
and an adjusted basic earnings per share increase of 9% to 
36.2 pence (2023: 33.3 pence). Revenue was marginally down 
at £110.7 million (2023: £113.3 million) reflecting (i) market 
conditions; (ii) a strong comparator in some consultancy areas; 
and (iii) the managed transition away from some legacy, low 
margin activities in the Defence sector. The Group’s reported 
statutory operating profit was £14.9 million for the year 
(2023: £8.1 million) and profit before tax was £14.7 million 
(2023: £7.6 million, which was impacted by one-off, non-cash 
adjustments associated with the TP Group acquisition). Cash 
generated from operations was £21.8 million in the year, reflecting 
the Group’s consistent focus on cash conversion.
Science Group retains a strong balance sheet. Despite returning 
£8.6 million to shareholders through share buy-backs (£5.0 million, 
2023: £3.9 million) and an increased dividend payment outflow 
of £3.7 million (2023: £2.3 million), at 31 December 2024 Group 
cash was £38.6 million (2023: £30.9 million) and net funds were 
£26.8 million (2023: £18.0 million). 
At 19 March 2025, adjusting for the cost of the Ricardo share 
purchases (including brokerage fees), Science Group retained 
gross cash of approximately £25.7 million and net funds of 
approximately £13.8 million. At the same date, the market value 
of the Ricardo investment was £25.6 million. Therefore, not only 
has the Ricardo shareholding produced a paper profit (in March 
2025) since investment, but Science Group retains significant cash 
resources, enhanced by a new unused debt facility.
Consultancy Services 
The Consultancy Division is an international services business 
providing advisory, product development, regulatory and 
project management services. The Division is characterised by 
deep technical and scientific expertise combined with specialist 
industry-sector knowledge. 
The collaboration between the different practices that make up 
the Division has progressively developed such that the Board 
is now unifying the operations under the Sagentia brand. The 
finance function across the Division has been fully integrated and 
is migrating to a consistent Finance IT platform, anticipated to be 
completed in summer 2025, enabling the business to maintain its 
high productivity and efficiency of operations. 
Reflecting the more challenging consultancy market in 2024, 
a strong prior year comparator in the Medical sector and 
management action to reduce some legacy, low margin activities 
in the TP Group Defence services business, for the year ended 
31 December 2024, the Consultancy Division generated revenue 
of £72.2 million (2023: £81.3 million), producing an adjusted 
operating profit of £17.9 million (2023: £20.4 million). The Division 
margin has been maintained at 24.9%, broadly the same as 
in 2023. The outlook for the year ahead reflects the ongoing 
refocusing to higher value-add activities in the Defence sector 
being broadly offset by growth in other sectors. 
Systems Businesses
The Group has two systems businesses, both of which have 
leading positions in their specialist markets. These businesses 
operate independently but are supported by the Group’s 
corporate and shared services infrastructure and leverage the 
Consultancy Division’s science, technology and engineering 
capabilities. In aggregate, for the year ended 31 December 2024, 
the Systems businesses reported significantly increased revenue 
of £37.8 million (2023: £31.2 million) and an adjusted operating 
profit of £5.8 million (2023: £2.2 million). 
CMS2 (Critical Maritime Systems & Support) designs, develops, 
manufactures and supports atmosphere management systems 
for submarines. The business services an international client 
base, but the UK Defence market accounts for around 70% of the 
revenue. 
Management action in the last two years has transformed the 
business, with revenue growing to £25.9 million, including 
around £5.6 million of low-margin pass-through materials, 
(2023: £21.3 million, 11 months, including £3.4 million of 
low margin revenue). Adjusted operating profit increased to 
£5.7 million (2023: £3.6 million, 11 months). Revenue and profit in 
2024 benefitted from prior years chargeable rate reconciliation, 
a standard retrospective process in the UK Defence sector. The 
Board anticipates that the business will continue to progress in 
2025 and continues to invest in next generation systems and 
technologies.  
Frontier is a market leading supplier of DAB/DAB+/Smart Radio 
chips and modules. Whilst the consumer electronics market has 
started to recover from the post-pandemic trough, it remains 
subdued in the weak UK and European economic environment. 
Revenue increased to £12.0 million (2023: £10.0 million) 
and the business returned to break-even, despite significant 
investment in new product development activities, all of which 
was expensed in the year with no capitalisation of R&D. Further 
business simplification and cost reduction was undertaken with 
the transitioning of the internet radio service infrastructure to a 
third party partner. The Board anticipates the Frontier recovery to 
continue in 2025.
Corporate
The corporate function is responsible for the strategic 
development and governance of the Group, ensuring alignment 
of business operations with Science Group shareholders. The 
underlying costs of the corporate function were £2.9 million (2023: 
£2.6 million) due to increased corporate activity in the year.
During 2024, the Company repurchased 1,080,507 shares at a 
total cost of £5.0 million (2023: £3.9 million), equivalent to an 
average price of 459.0 pence per share. At 31 December 2024, 
shares in issue (excluding treasury shares held of 1.4 million) 
were 44.7 million (2023: 45.5 million excluding treasury shares 
held of 0.7 million). The Board anticipates continuing the buy-
back programme in 2025, with an increased capital allocation of 
over £6.0 million and is recommending maintaining the dividend 
at 8.0 pence per share (2023: 8.0 pence per share), reflecting 
capital allocation preference in shareholder feedback. Subject to 
shareholder approval at the Annual General Meeting (‘AGM’), the 
dividend will be payable on 4 July 2025 to shareholders on the 
register at the close of business on 23 May 2025.
Science Group owns two UK freehold properties, Harston Mill, 
near Cambridge, and Great Burgh, near Epsom, the primary 
function of which is to host the Group’s operating businesses. 
The Group charges market rents to the operating businesses and 
lets out part of the Harston Mill site to third parties. For the year 
ended 31 December 2024, the rental and associated services 
income derived from this activity was £3.9 million (2023: £4.2 
million), with £0.6 million (2023: £0.8 million) generated from third 
party tenants. Intra-group rental charges are eliminated on Group 
consolidation. The last independent valuation of the freehold

Finance Director’s Report
Overview of Results
In the year ended 31 December 2024, the Group generated 
revenue of £110.7 million (2023: £113.3 million). Revenue 
from the Consultancy Services Division, that is revenue 
derived from consultancy services and materials recharged on 
projects, was £72.2 million (2023: £81.3 million) while Systems 
revenue generated by the CMS2 Business was £25.9 million 
(2023: £21.3 million) and Systems revenue generated by the 
Frontier Business was £12.0 million (2023: £10.0 million). External 
revenue generated by freehold properties, comprising property 
and associated services income derived from space let to 
third parties in the Harston Mill facility, was £0.6 million (2023: 
£0.8 million).
Adjusted operating profit for the Group increased to 
£21.5 million (2023: £20.5 million). The Group’s statutory 
operating profit of £14.9 million (2023: £8.1 million) reflects 
the amortisation of acquisition-related intangible assets of 
£4.4 million (2023: £4.9 million) and share-based payment 
charges of £2.3 million (2023: £2.0 million). Statutory operating 
profit increased relative to 2023 because of the increase in the 
underlying profitability of the Group, but additionally 2023 was 
impacted by one-off acquisition related adjustments relating 
to TP Group totalling £5.5 million. After net finance costs of 
£0.1 million (2023: £0.5 million) and a tax charge of £2.7 million 
(2023: £2.1 million), statutory profit after tax was £12.0 million 
(2023: £5.5 million). Statutory basic earnings per share was 
26.5 pence (2023: 12.1 pence per share).
Adjusted operating profit is an alternative profit measure that is 
calculated as operating profit excluding acquisition integration 
costs, amortisation of acquisition related intangible assets, share-
based payment charges, and other specified items that meet 
the criteria to be adjusted. Refer to the Notes to the Financial 
Statements for further information on this and other alternative 
performance measures.
Foreign Exchange
The acquisition of TP Group, where revenue is denominated 
in Sterling, has reduced the percentage of the Group’s overall 
exposure to foreign exchange, however there remains a 
reasonable proportion of the Group’s revenue denominated in 
currencies other than Sterling. In 2024, £32.8 million (equivalent 
to 30%) of the Group’s operating business revenue was 
denominated in US Dollars (2023: £34.6 million), including all of 
Frontier’s revenue. In addition, £1.8 million of the Group operating 
business revenue was denominated in Euros (2023: £3.9 million). 
The average exchange rates during 2024 were 1.28 for US Dollars 
and 1.18 for Euros (2023: 1.24 and 1.15 respectively). 
As in 2023, to provide greater forward visibility of foreign 
exchange movements, the Group acquired a currency exchange 
instrument to cap the Sterling:US Dollar rate in relation to certain 
Consultancy Division cash flows through to the end of 2024. The 
instrument applied to $1.0 million per month at an exchange rate 
of $1.25/£1, whilst still allowing the business to benefit from lower 
spot exchange rates when appropriate. A similar instrument has 
been put in place until the end of 2025 for $1.0 million per month 
at an exchange rate of $1.275/£1.
Taxation
The tax charge for the year was £2.7 million (2023: £2.1 million). 
The increase is reflective of the higher profitability, offset by the 
utilisation of tax losses and Research and Development (‘R&D’) tax 
credits. 
At 31 December 2024, the Group had £21.4 million (2023: 
£29.3 million) of tax losses, the largest component of which 
(£16.8 million) related to Frontier (2023: £19.2 million). Of the 
Frontier losses, £7.0 million (2023: £9.1 million) have been 
recognised as a deferred tax asset which is anticipated to be 
used to offset future taxable profits. The balance has not been 
recognised as a deferred tax asset due to the uncertainty in the 
timing of utilisation of these losses. Aside from these amounts, 
the Group has other tax losses of £4.6 million (2023: £4.2 million) 
unrecognised as a deferred tax asset due to the low probability 
that these losses will be utilised.
Financing and Cash
Cash from operations was strong at £21.8 million (2023: 
£10.3 million). Cash flow from operating activities (excluding Client 
Registration Funds) which takes interest payments and taxation 
into account, was £17.5 million (2023: £8.9 million). Reported cash 
from operating activities in accordance with IFRS was £18.5 million 
(2023: £7.9 million). The difference in these two metrics relates 
to the fact that one of the Group’s businesses, TSG, processes 
regulatory registration payments on behalf of clients. The 
alternative performance measure, by excluding Client Registration 
Funds, reflects the Group’s available cash position and cash flow. 
The Group cash balance (excluding Client Registration Funds) 
at 31 December 2024 was £38.6 million (2023: £30.9 million) 
and net funds were £26.8 million (2023: £18.0 million). Client 
Registration Funds of £2.9 million (2023: £1.9 million) were held at 
the year end. 
Subsequent to the year end (in March 2025), the Group renewed 
its bank borrowing facilities: 
•	
The 2016 Term Loan has been replaced with two new Term 
Loans with a combined value of £12.0 million for a 10 year 
period, secured solely on each of the Group’s freehold 
properties. The interest margin of 2.6% is the same as the 
2016 Loan. Interest rate swaps will fully hedge the two new 
Loans resulting in a 10-year fixed effective interest rate of 
approximately 7.3%, comprising the SONIA lending margin 
plus the swap rate. In connection with repaying the 2016 
Loan early, and settling the interest rate hedging associated 
with that Loan, the Group will realise a one-off benefit, with 
corresponding cash inflow, of approximately £0.6 million.
•	
The 2021 Revolving Credit Facility (‘RCF’) has been replaced 
with a new 5 year RCF of £30.0 million (with an additional 
£10.0 million accordion option, subject to approval). The new 
RCF is at a rate of 1.95% plus SONIA.
Working capital management continued to be a strong focus for 
the Group with debtor days of 36 at 31 December 2024 (2023: 
40 days) and inventory days of 76 (2023: 121 days).
Ricardo plc
In February and March 2025, the Group commenced purchasing 
shares in Ricardo, incrementally increasing its holding to 16.2% 
(as at 19 March 2025). These purchases were funded from the 
Group’s existing cash resources.
Share Capital
At 31 December 2024, the Company had 44,738,465 ordinary 
shares in issue (2023: 45,458,972) and the Company held an 
additional 1,447,409 shares in treasury (2023: 726,902). The voting 
rights in the Company at 31 December 2024 were 44,738,465 
(2023: 45,458,972). In this report, all references to measures 
relative to the number of shares in issue exclude shares held in 
treasury unless explicitly stated to the contrary.
Jon Brett 
Finance Director
Statement of Executive Chair continued 
properties (December 2023) indicated an aggregate value in the 
range of £16.9 million to £31.6 million, although for consistency 
the properties are held on the balance sheet on a cost basis of 
£20.8 million (2023: £21.0 million).
The Group’s Term Loan and Revolving Credit Facility (‘RCF’) were 
scheduled to expire in 2026. In order to support the Group’s 
corporate strategy, the Board undertook an early process to 
refinance these facilities and in March 2025 confirmed: 
•	
Two new Term Loans with a combined value of £12.0 million 
for a 10 year period, secured solely on the Group’s freehold 
properties at the same margin as the previous (2016) 
Loan, and
•	
A new RCF on a 5 year term of £30.0 million (with an additional 
£10.0 million accordion option, subject to approval) at a 
significantly lower margin of 1.95% above SONIA.
Interest rate swaps will fully hedge the two Term Loans. In 
connection with repaying the 2016 Loan early, the Group 
will realise a one-off benefit, with corresponding cash inflow, 
associated with the interest rate hedging on that loan of 
approximately £0.6 million. 
Investment in Ricardo plc
Ricardo is a UK-based science and technology consultancy 
and engineering business with similar skills to Science Group, 
operating in complementary markets. Science Group has been 
monitoring Ricardo for some time with more intensive analysis 
undertaken in the second half of 2024 and early 2025.
The Ricardo profit warning at the end of January 2025 was 
anticipated and in mid-February Science Group commenced 
acquiring shares in Ricardo. At 19 March 2025, Science Group is 
the second largest shareholder in Ricardo with a holding of 10.1 
million shares, equivalent to a 16.2% stake. This investment has 
been acquired at an average cost (including brokerage fees) of 
231.0 pence per share, around 15 year low share price levels. On 
19 March 2025, the Ricardo share price closed at 254.0 pence per 
share. 
Science Group has had dialogue with the Ricardo Board in 
relation to managing the investment. The Ricardo poor financial 
performance, with weak cash conversion and a stretched balance 
sheet, has led to a significant degradation of shareholder value in 
this once great British company. The contrast to Science Group 
and its record earnings per share, for similar consultancy and 
systems businesses, is stark. A catalyst for change is required to 
restore shareholder value in Ricardo and to address the ineffective 
governance. 
Science Group acquired its material stake in Ricardo in a 
timely and effective manner. As a result, from a purely financial 
perspective, down-side risk has been mitigated and a paper profit 
(approximately £2.3 million) achieved at 19 March 2025. However, 
as the second largest shareholder in Ricardo, a variety of options 
to enhance and/or realise value from the investment, over a short, 
medium or long time horizon, are open to Science Group and all 
options will be evaluated. 
Summary and Outlook
In summary, Science Group reports another solid performance in 
2024, despite economic and political volatility, maintaining strong 
margins with record adjusted earnings per share, the primary 
metric for shareholder value. The Consultancy Services Division 
was somewhat affected by the market instability, but this was 
offset by the performance of CMS2 resulting from the successful 
turnaround of that business. Accordingly, the Group’s strategy 
again demonstrates resilience and translates into tangible results. 
Most importantly, adjusted operating profit translates into cash. 
Science Group’s strong balance sheet provides a robust 
foundation for the Group while also enabling the Board to pursue 
corporate opportunities in a timely manner, as evidenced by the 
recent investment in Ricardo. Even after the Ricardo investment, 
Science Group retains significant cash resources, enhanced by the 
recent renewal and increase of finance facilities. 
Similarly, while the Science Group share price has consistently 
outperformed the relevant market indices, the Board remains 
focused on translating operating performance into shareholder 
value. Accordingly, the Board, anticipates allocating capital to 
continuing and increasing the share buyback programme in the 
year ahead.

STRATEGIC REPORT

Operational risks continued
Mitigation
Consultancy projects over-run or fail to meet technical milestones
Consultancy projects may over-run and/or may fail to meet 
technical milestones because the nature of the work undertaken 
by the Consultancy Division is technically challenging. Project over-
runs may lead to loss of margin on projects and overall profitability.
The Group contracts the majority of consultancy projects on a time 
and materials basis. The risks of project failures are mitigated by the 
Group’s internal project management processes including formal 
bid review processes, regular reviews to assess whether the revenue 
recognised on work in progress is a fair representation of actual costs 
incurred and estimated costs to completion, regular formal project 
board review meetings for large projects, and customer meetings to 
review progress.
Key personnel
The Group relies on recruiting and retaining highly qualified 
technical experts on whom the Group depends to deliver its 
services and products. Failure to recruit and retain key staff could 
threaten the Group’s ability to deliver projects to its customers, to 
win new work or to maintain market competitiveness. 
The Group’s growth also places greater demands on the 
Group’s management and infrastructure across a wider range of 
geographical locations and markets. Failure to recruit and retain key 
management and functional staff could increase the risks associated 
with operational and financial controls, sales and marketing, 
information technology and other functional support areas. 
The Group encourages staff retention through both competitive 
remuneration packages and a stimulating work environment. The 
Group’s growth also provides career opportunities across the Group. 
In addition to base salary, remuneration can include annual bonus 
or profit share, pension contributions, health benefits, life assurance 
and share option awards, and the remuneration components are 
reviewed regularly. 
Efforts are made to foster a vibrant, dynamic and supportive 
environment for employees, offering diverse, technically challenging 
work for large and small customers across a range of industries and 
specialist market, science and technology areas. 
Loss of a major customer
Loss of one of the Group’s large customers may impact the Group’s 
revenue and/or profit.
The diversity of the Group’s businesses across market sectors and 
geographies mitigates against the loss of a major customer. 
Cyber security 
Cyber security threats pose a risk to confidential or sensitive 
data held in the normal course of business as well as business 
interruption risk. A breach of cyber security could result in a loss of 
data, damage to the Group’s reputation and breach of customer or 
other contracts. 
The Group enforces appropriate IT controls, continuously reviewing 
the quality of its security shields and protocol, and implementing 
regular cyber awareness training for all staff, test phishing campaigns 
and penetration testing. Networks used by those Group businesses 
operating in the defence industry hold ISO 27001 (Information 
Security Management) and Cyber Essentials Plus certifications and 
other accreditations. 
Geopolitical considerations
The conflict in Ukraine and its impact on energy prices has resulted 
in significant operational cost increases for the Group’s freehold 
properties. While energy costs reduced to some extent in 2024, 
they remain high and may increase again throughout 2025.
Global energy and fuel prices also impact materials costs, 
employee remuneration and other costs, and the Group may not 
be able to pass increases onto customers. 
The Group monitors energy prices, fixing prices where appropriate 
and seeking to reduce energy usage. 
In addition to its engineering base near Cambridge, UK, the 
Frontier business has an office in Shenzhen and also has 
employees in Hong Kong. Political instability in Asia may affect local 
employees and suppliers and therefore impact Frontier’s sales, 
product development and manufacturing functions. 
The Group seeks to mitigate the risk of interruption to its usual 
business activity in Asia by ensuring that product knowledge, 
documentation, systems and data are backed up and replicated in 
the UK offices on a daily basis. Manufacturing of Frontier products is 
outsourced and could be replicated in other locations.
Supply chain availability
The CMS2 and Frontier businesses rely on the supply of 
components for the manufacture of their products. An inability to 
source these components in sufficient quantities is a risk to these 
businesses’ ability to fulfil customer orders. Component shortages 
may also result in increased prices which may not be able to be 
passed on to customers. 
In the Frontier business, a reduction in consumer demand may 
result in high levels of inventory which may not be fully utilised. 
The Group proactively manages inventory levels and seeks to identify 
alternative, cheaper suppliers of certain key components.
Key Performance Indicators 
The key performance indicators (‘KPIs’) are revenue, operating 
profit, cash flow and the alternative performance measures as 
disclosed in Note 1 in the Notes to the Financial Statements. 
Profitability of the business is managed primarily via the review of 
revenue and adjusted operating profit. Working capital is reviewed 
via measures of trade receivables and inventory. Performance 
against KPIs is reported in the Finance Director’s Report.
Principal Risks 
The Directors consider that the principal and emerging risks 
facing the Group, including those that would threaten the 
sustainability of its business model, its future performance, 
solvency or liquidity, are as set out below. 
The Group reviews, analyses and addresses the risks it faces 
through the Board, Audit Committee, Executive management and 
business management teams, and project and functional reviews. 
The frequency of reviews depends on the nature of the risk and 
may vary from weekly to annually. Project risks are generally 
reviewed at least monthly. 
The Group maintains a risk register which is reviewed by the 
Board in full at least once a year. The Board also regularly reviews 
key existing and emerging risks across the Group on a monthly 
basis. The Board considers this monthly period to be appropriate 
for the business as it allows the Board to remain informed of 
developments that may affect the delivery of its strategy and to 
identify and implement any mitigating actions. It also supports the 
Board’s review and revision of forecasting, undertaken on at least 
a quarterly basis, to minimise the impact of any emerging risks to 
the Group. A summary of the key measures taken to mitigate the 
identified risks are set out below. 
The Group uses internal and external methods to help identify 
emerging business risks. Internally the Managing Directors 
of the operating businesses report weekly to the Executive 
management team on business performance and issues, and 
provide formal reports to the full Board on a monthly basis. This 
ensures that potential emerging risks identified on the ground are 
escalated to the Board in a timely manner. Externally, the Group’s 
professional advisors raise relevant potential issues from time to 
time. Identified potential risks are discussed by the Board and, 
if necessary, risk mitigation strategies are considered. Identified 
risks may also be assigned to a working party to keep a watching 
brief and update the Board as appropriate. 
Operational risks
Mitigation
Economic conditions impacting demand for services 
The Consultancy Division is dependent on the market for 
outsourced science, technology, engineering, regulatory and 
project management services. An economic downturn or instability 
may cause customers to delay or cancel projects or to use internal 
resources instead. 
The current economic uncertainty and potential for recession in 
the Western economies may impact both the total investment 
and the investment priorities of the Group’s customers. In 
particular R&D investment allocated to long-term initiatives may be 
negatively impacted.
The Group seeks to diversify exposure across geographical markets, 
increasing the number of market sectors in which it operates, 
types of customers and range of service offerings. The Group also 
undertakes marketing activities to inform current and prospective 
customers regarding the benefits of outsourced services and Science 
Group’s proven ability to fulfil those objectives. 
The Group also seeks to exploit opportunities resulting from a 
reduction in customers’ internal resources which may result in 
greater levels of outsourcing for business critical projects.
Financial circumstances of customers
A deterioration in the global economic climate and/or financial 
failure of customers or potential customers may adversely affect 
the profitability of the Group, including by customers defaulting on 
or delaying the payment of invoices.
The Group actively manages customer relationships including 
credit limits which, if appropriate, may require payment in advance, 
regularly reviews debtors and overdue payments, and has proactive 
credit control procedures.
Reputational risk 
Failure to deliver service or product deliverables to agreed 
budgets, timetables and/or quality may result in reputational 
damage to Science Group that may adversely affect future sales. 
The Group operates Quality Assurance procedures, review meetings 
with customers, formal customer feedback procedures, and holds 
various quality certifications in the relevant businesses including 
ISO 9001 (Quality Management Systems), ISO 13485 (Quality 
Management Systems for Medical Devices), ISO 17025 (Testing 
and Calibration Laboratories) and ISO 27001 (Information Security 
Management). 
In the Group’s systems businesses, testing is undertaken prior to 
release of new products and remedial action taken in a timely manner 
when faults are reported.
The Frontier business relies upon third party factories to 
manufacture its product modules and upon its customers to 
manufacture complete consumer products on behalf of end-
client consumer brands. Any deterioration in quality in these 
manufacturing facilities may impact the Frontier brand and its 
ability to sell product and/or maintain margin. 
Frontier maintains long term relationships with trusted partner 
factories and relationships with end-client consumer brands to obtain 
product quality feedback.

STRATEGIC REPORT

Strategic risks continued
Mitigation
UK defence policy
Businesses operating in the Defence and Aerospace industries, 
in particular the TPG Services and CMS2 businesses, may be 
impacted by changes in Government defence policies and 
legislation. This may lead to a risk of delay to or loss of customer 
contracts. 
The Group seeks to develop long-term, close working relationships 
with customers and to maintain current industry knowledge 
providing visibility of future defence programmes and spend. 
Technology advances 
The ongoing development of new and existing technologies 
provides opportunities for Science Group to provide market-
leading products and services to its customers. The Group’s 
personnel must stay at the forefront of technical advances and 
understanding of technical specialisms in order to exploit these 
opportunities and sustain the Group’s growth. 
Management teams regularly identify and review new technical areas 
for investment, employees are encouraged to keep up to date on 
technological developments by both formal and informal training 
and self-learning in relevant areas of technical expertise, and where 
appropriate recruitment is targeted at employees with new technical 
skills where gaps in expertise are identified.
Generative AI
Generative AI technologies may have the potential to negatively 
impact the provision of lower-value consultancy services by 
delivering such services with a higher degree of automation.
The Group regularly evaluates potential Generative AI tools and use 
cases to assess their potential use in both internal work and the 
provision of high-value services to customers. The Group operates a 
human-led approach to all work to maintain quality standards.
Financial risks
Mitigation
Inflationary pressures 
Inflation in the global economy is a risk across the Group including:
•	
increased costs from suppliers which may impact all 
businesses.
•	
increases in living costs including fuel, energy and food costs 
which may impact employees. 
•	
wage inflation and associated pressure on salaries and 
remuneration packages for both specialist skills in technology 
and science as well as functional skills such as human 
resources, marketing and finance. 
The Group may or may not be able to pass on supply chain price 
increases or higher employee costs to customers.
The Group proactively manages inflation where practicable. This 
includes negotiating customer pricing or fee rate increases and 
building inflationary cost increases into financial plans. 
Currency exchange rates 
A significant proportion of the Group’s revenues are invoiced in 
currencies other than Pounds Sterling, including but not limited 
to the US Dollar and Euro, whilst the majority of the Group’s 
employee-based costs are incurred in Pounds Sterling. In addition, 
materials related to Frontier products are typically priced in US 
Dollars and end products are generally sold priced in US Dollars. As 
a result, variations in currency exchange rates may have a material 
impact, either positive and negative, on Group revenue and profit 
performance.
In 2024 the Group procured two currency exchange instruments to 
cap the Sterling:US Dollar rate for the R&D Consultancy business 
until the end of 2025, having first procured similar instruments 
in 2022 and 2023. These instruments provide the business with 
improved visibility and reduced volatility. In addition, the Group seeks 
to mitigate foreign currency exposure and volatility by transferring 
excess foreign currency holdings into Pounds Sterling on a 
regular basis.
Decrease in value of freehold properties
The Group owns two large freehold properties which may increase 
or decrease in value. The Group’s bank facilities are secured on 
these properties.
The Group maintains these properties on a long term basis primarily 
for its own use. Maintenance is undertaken by dedicated on site 
facilities teams and specialist external contractors. The properties are 
also protected by appropriate insurance policies. 
Operational risks continued
Mitigation
Market for radio products
The Frontier business has a high market share of the DAB radio 
and counter-top smart radio markets and is therefore subject to 
market demand and the competitive environment. These factors 
are correspondingly affected by the economic climate, a reduction 
in consumer spending and alternative methods of receiving radio/
audio programmes. This has been reflected in the challenging 
conditions experienced across the consumer electronics sector in 
2023 and 2024. 
The market for consumer electronics goods is price sensitive. 
Frontier’s products are manufactured in Shenzhen and local 
conditions such as import tariff changes and shipping may also 
impact the cost of radio production and therefore the selling 
price to the end consumer, which may affect demand and/or the 
margins of the business. 
The Group actively monitors market developments, focussing on 
operational efficiencies and adjusting material purchases. The Group 
also has employees based in Asia to manage relationships with 
customers and manufacturing locations. The switch off of FM services 
in certain geographies may provide opportunities for increasing DAB 
sales. 
Litigation
All project contracts carry possible litigation risks including the 
potential for product or professional liability claims, intellectual 
property infringement claims and other warranty and indemnity 
claims. 
In particular the Consultancy Division has a significant exposure to 
the US, where there is a higher propensity for litigation and where 
the Group may also be required to respond to court orders relating 
to disputes between third parties. Any litigation has the potential 
for significant cost, management disruption and reputational 
damage.
Contractual risks are mitigated through internal approvals processes, 
the use of standard commercial terms where practicable or otherwise 
negotiating appropriate contractual protections, and relevant 
insurance policies. 
Legislative or regulatory changes
Changes in legislation or regulation may result in increased costs 
and/or interruptions to business processes. This may include 
changes relating to health and safety, environmental, privacy or 
social issues, trading, taxation or accounting practices. 
The Group monitors forthcoming legislative and regulatory changes 
to enable assessment of and planning for business impacts and to 
ensure compliance. External advice is sought where required. 
Loss or unavailability of Group sites
The unavailability of Group sites may impact the Group’s usual 
business operations. 
Where required, much of the Group can continue to operate with 
limited site facilities. Resilience is also provided through the Group’s 
two large freehold sites in the UK, both with laboratory facilities. 
Significant external event impacting normal business operations (for example, pandemic)
A significant external event may restrict the Group’s ability to 
undertake its usual business operations or meet customer 
demands. 
The Group has invested in software and communications tools to 
enable a combination of remote and essential office-based working 
where required. The diversity of the Group’s businesses, customers 
and sites also mitigates potential impacts. 
Strategic risks
Mitigation
Acquisitions & strategic investments
The Group has grown through the acquisition of companies 
with compatible service and technology offerings. Acquisitions 
and strategic investments may bring risks in respect of value, 
integration, distraction of key personnel and legacy onerous 
obligations. 
Acquisition risks are mitigated so far as practicable by the acquisition 
decisions and processes being led by the Board and Executive 
management team. External advice and expertise are engaged as 
required. Risks are also mitigated by the potential for growth and 
diversification, whilst increased scale provides efficiencies of back 
office functions across the Group.
The Board considers further acquisitions and strategic investments 
to be a core part of the Group’s strategy and the Group is continually 
monitoring for opportunities.

Section 172 Statement 
The Companies (Miscellaneous Reporting) Regulations 2018 require qualifying companies to publish a statement explaining how the 
Directors have had regard to the matters set out in section 172(1)(a) to (f) of the Companies Act 2006 (Act) in performing their duties under 
section 172. 
In accordance with section 172, the Directors confirm that they have continued to act in such a way that they consider, in good faith, would 
be most likely to promote the success of the Company for the benefit of its shareholders as a whole and, in doing so, have had regard to the 
matters set out below. 
Section 172 matters
How the Board has regard to these matters
Page reference
The likely long term consequences of 
decisions
The Directors regularly consider the long term consequences of 
the Board’s decisions and actions. The Board oversees the Group’s 
strategy and closely monitors progress against financial and other 
plans throughout the year, both at a Group and divisional level. The 
Board also considers the Group’s commercial and operational risks 
and how to protect shareholder value.
For more information see the Principal Risks section and the Principal 
decisions made during the year.
6-10, 12
The interests of the Company’s employees
The Board recognises that the Group’s employees are essential to its 
success and the Directors take a keen interest in the development 
and retention of key employees across the Group. The Executive 
Directors regularly engage with Managing Directors, management 
teams and other employees across the Group to understand 
business-specific issues.
For more information see the Social section of the Non-Financial and 
Sustainability Information Statement, the Statement on engagement 
with employees, and the Report of the Remuneration Committee. 
15, 23, 26
The need to foster business relationships 
with suppliers, customers and others
While there are circumstances in which the Executive Directors 
engage directly with certain stakeholder groups or on certain issues, 
the structure of the Group means that engagement with customers 
and suppliers usually takes place at an individual business level. 
The Board supports the senior management teams in fostering and 
maintaining good relationships. The Board monitors relationships 
with key customers and suppliers through the Executive Directors 
and the Managing Directors. The Managing Directors provide 
updates on significant issues in their businesses on a weekly basis to 
the Executive Directors and as part of their monthly reporting directly 
to the full Board. 
For more information see the Statement on engagement with 
customers, suppliers and others.
23
The impact of the Company’s operations on 
the community and the environment
The Directors are conscious of the importance of investing in and 
caring for the physical environments in which the Group operates 
and contributing to its local communities. These factors are key to the 
Group’s ongoing work to reduce and manage its use of energy, water 
and other resources, and its charitable donations. 
For more information see the Environmental and Social sections of 
the Non-Financial and Sustainability Information Statement and the 
Climate-Related Financial Disclosures. 
13, 14, 17
The desirability of maintaining a reputation 
for high standards of business conduct
The Board sets out the values and standards of behaviour expected 
from all of its employees through the Group’s corporate values. 
This is supported by the Group’s governance and compliance 
framework which requires adherence to a range of Group policies 
and procedures including anti-bribery and whistleblowing policies. 
The Directors are committed to high standards of business conduct 
throughout the Group and take into account the desirability of 
maintaining its reputation for the same in their decision making. For 
more information see the Governance section of the Non-Financial 
and Sustainability Information Statement.
16
The need to act fairly as between 
shareholders
The Directors are committed to treating all shareholders equally 
and, as part of its decision making process, the Board considers the 
interests of shareholders as a whole. The Board recognises that it 
may need to balance competing interests in reaching its decisions 
and, where there are conflicting interests, the Board will act as 
equitably and fairly as it is able to do. 
For more information see the Relations with shareholders section of 
the Corporate Governance Report.
25
In accordance with the UK Corporate Governance Code January 
2024, the Board has determined that a three year period to 
December 2027 constitutes an appropriate period over which to 
provide its viability statement. The viability assessment considers 
solvency and liquidity over a longer period than the going concern 
assessment which covers a period to June 2026. Inevitably, the 
degree of certainty reduces over the longer period.
The Board prepares a detailed financial plan annually, forecasting 
sales and costs at a departmental level and a Group cash 
flow covering this period. The plan provides a prudent basis 
of assessment whilst enabling the Group to remain agile in 
implementing significant opportunities for further growth when 
they arise. Performance against the financial plan is reviewed on 
a monthly basis by the Board and forecasts are updated at least 
quarterly. 
The Board has considered sensitivity analyses reflecting downside 
scenarios of principal risks (for example a downturn in market 
demand) applied to the Group’s financial plan and cash flows 
(extended to 18 months from year end).
The scenarios assume an appropriate management response 
to the specific event, but not broader mitigating actions which 
could be undertaken and which have been considered separately. 
Reverse stress testing has also been performed to assess the 
severity of scenario that would have to occur to exceed headroom. 
The assessment took account of the Group’s current funding, 
forecast requirements and existing committed borrowing facilities. 
In conclusion, the financial plan withstood the stress testing and 
application of downside scenarios.
In each scenario or combination of sensitivity scenarios applied 
to the financial plan, the Group is able to rely on its cash reserves, 
reduce capital expenditure and take other cost and/or cash 
management measures to mitigate the impacts and still have 
residual capacity to absorb further unanticipated events. 
The financial plan and going concern review formed the basis of 
the extended viability assessment. The Board has also considered 
the effect of the banking covenants for this assessment period 
and noted that there is no expectation of covenant breach, 
particularly as the Group ends the year with Net Funds of £26.8 
million (2023: £18.0 million). Based on the results of these 
analyses, the Directors have a reasonable expectation that the 
Group will be able to continue in operation and meet its liabilities 
as they fall due over the three year period of this assessment.
Financial risks continued
Mitigation
Treasury
Liquidity risk
The Group maintains a strong cash balance and also has access to an 
undrawn RCF facility. The Group ensures it can access sufficient cash 
to meet any potential short term needs.
Credit and counterparty risks including customer, supplier 
and banks
Credit risk with customers is actively managed with weekly review 
meetings by local management teams and monthly review by the 
Board. 
Key suppliers are subject to Executive management approval 
including a review of financial position. 
The majority of the Group’s cash is held in large UK banks with 
regular reviews of cash levels across other countries and accounts. 
Interest rate risk
The Group has interest rate swap instruments to fix interest and 
remove risk and volatility. 
Covenant breach
The Group’s debt facilities include no operating covenants. The risk 
of breaching financial covenants is mitigated by maintaining a strong 
cash balance. Covenants are reviewed monthly by the Board.

includes the Environmental, Social and Governance section below 
and the Climate-Related Financial Disclosures on page 17. 
Environmental, Social and Governance
The Directors are committed to acting in accordance with high 
levels of ethics and governance. A review of the Group’s approach 
to sustainability and societal impact during the year is set out 
below. 
Environmental
The Group is committed to managing the environmental impact 
of its activities and to improving resource efficiency and reducing 
waste. The Directors consider that, due to the nature of the 
Group’s operations, it does not have a significant impact on the 
environment. In particular, the Group’s consultancy businesses 
deliver consultancy-based projects performed by staff in office 
and laboratory facilities, and do not use large quantities of raw 
materials or processes that impact the environment. However, the 
Group seeks to minimise its carbon impact and recognises that 
its activities should be carried out in an environmentally friendly 
manner where practicable. Where relevant, the Board has regard 
to environmental factors in relation to its strategy and decision 
making. 
The Group’s Streamlined Energy and Carbon Reporting (‘SECR’) 
is included below. See page 17 for the Group’s Climate-Related 
Financial Disclosures. 
Energy and greenhouse gas (‘GHG’) reporting 
Science Group reports its environmental performance in 
accordance with the UK Government’s Streamlined Energy and 
Carbon Reporting Guidance as required under the Companies 
(Directors’ Report) and Limited Liability Partnerships (Energy and 
Carbon Report) Regulations 2018. The Group’s methodology for 
this reporting has been developed following the GHG Protocol 
Corporate Accounting and Reporting Standard and GHG 
emissions are assessed using the 2024 emissions conversions 
factors published by the Department for Energy Security and 
Net Zero. 
The table below summarises the GHG emissions for the year 
ended 31 December 2024 on a UK basis. This is the Group’s 
second year of SECR reporting and the 2023 assessment results 
included below constitute the baseline year for comparison. The 
2023 results have been restated to reflect improved data accuracy 
and the inclusion of flight emissions data. 
The Group continues to refine its data collection to improve 
the accuracy and reliability of GHG emissions reporting for 
future years.

Section 172 Statement continued
Principal decisions made during the year
Some of the key decisions considered by the Board in 2024, taking into account the likely long term consequences and the interests of 
stakeholders, are set out below.
Currency exchange instrument
The Company procured two currency exchange instruments to cap the Sterling:US Dollar 
rate in relation to the R&D Consultancy business through to the end of 2025. This is in line 
with previous currency hedging since 2022 as a result of increased currency volatility. The 
Directors considered that the hedges remained appropriate to provide the business with 
improved visibility and reduced volatility. 
New term loan and RCF
The Group’s current term loan and revolving credit facility were due to expire in late 2026. In 
order to support the Group’s corporate strategy, the Board initiated an early refinancing to 
renew, increase and extend these facilities. The Directors considered that these new facilities, 
combined with the Group’s existing cash resources, would strengthen the Group’s ability to 
continue to consider corporate opportunities which may arise. See Note 29 to the Financial 
Statements for further details.
Discretionary buyback programme
In October 2024 the Company appointed Panmure Liberum Limited to manage the buyback 
of Company shares on an independent basis, subject to defined pre-agreed parameters, to 
enable the buyback to continue during closed periods until the earlier of the next Annual 
General Meeting and 30 June 2025. The Directors considered the discretionary buyback 
programme to be in shareholder’s interests given the Group’s balance sheet, cash resources 
and operating cashflow, and the current share price. 
Dividend
In considering the appropriate level of dividend payment to shareholders, the Board took 
into account the need to maintain cash resources to implement both organic and strategic 
investment opportunities and acquisitions, and the varying interests of investors.
Acquisitions and investments
The Company is acquisitive and regularly considers potential acquisitions and strategic 
investment opportunities. Throughout the year the Board considered a number of potential 
acquisitions although none were considered to be appropriate investments taking into 
account the Group’s strategy, the financial impact and likely operational and other risks.

STRATEGIC REPORT

Social
Science Group takes its responsibilities as a corporate citizen 
seriously in the territories in which the Group operates. The 
Board’s primary goal is to create shareholder value but in a 
responsible way which serves all stakeholders including the 
communities within which the Group operates. Furthermore, 
Science Group seeks to continually enhance and extend its 
science and technology contribution to society through the work 
the Group undertakes with its customers and in areas where the 
Group decides to invest and explore directly.
The Board regularly monitors the Group’s culture and practices, 
including the review of recruitment, retention and turnover data, 
health and safety reports, and reports from senior managers 
within the Group.
Diversity, equity and inclusion
Science Group is committed to supporting diversity, equity and 
inclusion (‘DEI’) among its employees. The Group’s employment 
policies are non-discriminatory, particularly on the grounds of 
any protected characteristic. This includes, but is not necessarily 
limited to, age, gender, nationality, ethnic or racial origin, disability, 
religion or belief, pregnancy and maternity, sexual orientation 
or marital or civil partnership status. Science Group gives due 
consideration to all applications and provides training and the 
opportunity for career development wherever possible. The Board 
does not support discrimination of any form, positive or negative, 
and all appointments are based on merit. 
The Group operates a DEI committee to discuss, implement and 
monitor various DEI initiatives. During 2024 these included:
•	
Engagement with women in the Group: An ongoing series of 
lunches for senior and mid-level women across the Group to 
provide networking opportunities and support, establishment 
of local “Lean In Circles”, and executive-level engagement with 
junior women to foster communication and opportunities.
•	
Menopause support: Practical support for women including a 
monthly support group, awareness training for line managers, 
and improvements to relevant health benefits.
•	
Recruitment practices: Ongoing monitoring of recruitment 
panels to ensure the inclusion of diverse representation and 
review of job adverts for unconscious gender bias.
•	
Diversity data collection: A voluntary, anonymous diversity 
questionnaire was run for employees in the CMS2 and TPG 
Services businesses (not included in the 2023 survey) with a 
60% response rate.
•	
Veterans: The TPG Services business has signed the Armed 
Forces Covenant and supports Armed Forces Day each year. 
The Board reviews reports on DEI matters at least twice a year. 
No Science Group company is currently required to report on its 
gender pay gap. However, the Group monitors the relevant data 
and the Board reviews this annually. 
The Group currently has native speakers of around 25 languages. The gender ratios for the number of persons employed by the Group at 
the end of the year are set out in the table below.

Employee training and development
Science Group’s employees are its primary asset and the Board 
is committed to nurturing their abilities, investing in career 
development and rewarding exceptional performance. The Group 
offers training and mentorship to allow ambitious individuals 
to thrive within their environment and realise their personal 
potential. Employee performance is aligned to the Group’s 
objectives through an annual performance review process and 
ongoing project management, line management and mentorship 
feedback. Formal training and career development is offered 
to staff of all levels through internal and external programmes 
that cover technical, business and managerial advancement 
opportunities. Beyond formal training, employees also hold 
informal lunchtime sessions on a regular basis to enable 
knowledge and skills transfer amongst teams.
The Group regularly takes one year or summer student 
placements and the CMS2 business runs an apprenticeship 
programme. The Group also supports employees across the 
Group with extra-curricular studies and qualifications in relevant 
fields. 
Financial rewards and support
Employee remuneration and incentives are overseen and 
approved by the Remuneration Committee. In addition to its 
standard remuneration and benefits packages, the Group invests 
in and rewards its workforce through the operation of its bonus 
and profit share schemes for qualifying employees, its share 
option scheme and other discretionary incentives. During 2024 
additional discretionary payments were made to employees 
reflecting individual performance. For more information see the 
Report of the Remuneration Committee on page 26.
Health and wellbeing
The Group’s employee assistance programmes and other benefits 
are available for employees to access a range of medical, financial, 
wellbeing and other support services and information. Mental 
Health Awareness Week is given a particular focus each year in 
the UK with site-specific programmes of activities and support. 
The majority of employees are also eligible for private medical 
insurance.
Energy efficiency 
The Group considers energy efficiency initiatives on an ongoing 
basis. Science Group owns two large freehold sites near 
Cambridge and Epsom where many energy efficiency measures 
have already been implemented but incremental improvements 
continue to be made. At its leased properties there are varying 
opportunities to influence energy efficiency according to lease 
terms and landlord responsibilities and these are assessed on a 
case by case basis. 
For the freehold properties and other sites where the Group 
purchases gas and/or electricity, this is purchased from renewable 
sources so far as practicable. Most lighting at the Cambridge and 
Epsom sites has been upgraded from fluorescent to LED with the 
remainder, as well as lighting at the Portsmouth manufacturing 
site, being upgraded when reaching end of life. LED lighting is 
installed as standard in new office fit outs. Lighting automation 
is used across all large sites as appropriate in lesser used areas, 
with more installed in Epsom during the year. At the Cambridge 
site the boilers and chillers have been progressively upgraded 
to energy efficient versions. Thermal imaging surveys of the roof 
are used to identify areas requiring new insulation. At the Epsom 
site the original chillers have been replaced with energy efficient 
versions and excess capacity has been reduced. At both freehold 
sites and Portsmouth, air conditioning and air handling systems 
are programmed to increase efficiency and implement timed shut 
downs when not required. 
The Group undertakes energy audits periodically and implements 
practicable recommendations. The Group has previously 
considered the installation of solar panels at the Group’s freehold 
sites, but this was not found to be economically viable. 
Waste and recycling
The Group’s Waste Management Policy supports the continued 
reduction of waste and, where practicable, re-use and recycling 
of consumables with incremental improvements implemented 
during the year. All large sites facilitate the separation of office 
waste into recycling and general waste. The Cambridge and 
Epsom sites also provide separate facilities for food waste. 
Commercial waste is collected in skips at the Cambridge, Epsom 
and Portsmouth sites. All office and skip waste collections are 
processed by the Group’s waste management contractors at 
recycling centres. The Portsmouth site also separates scrap metal 
for recycling.
Confidential waste, both paper and hardware, is disposed of by 
specialist suppliers and recycled once shredded. Electronic waste, 
ink cartridges, fluorescent tubing, and chemical and biological 
waste are disposed of responsibly through specialist suppliers and 
in accordance with applicable regulations including the Restriction 
of Hazardous Substances (‘RoHS’) Directive and the Waste 
Electrical and Electronic Equipment (‘WEEE’) Directive.
Water usage
Given the nature of the Group’s businesses, total water 
consumption is relatively low, being largely limited to office-based 
consumption from bathroom and kitchen facilities. However, the 
Group proactively manages the use of water within its sites and 
seeks to implement water reduction measures where practicable.
Travel
Electric vehicle charging points are installed at the Cambridge and 
Epsom sites for employees’ usage to encourage a move away from 
petrol and diesel vehicles. All Science Group companies in the UK 
offer employees access to the Government Cycle to Work initiative 
offering tax free bicycles as part of the Group’s standard employee 
benefits offering. The Group also makes significant use of virtual 
meetings where appropriate and has a US-based sales team to 
reduce trans-Atlantic travel.
Ecology and conservation
The Cambridge site includes woodland and grassland areas 
and a tributary of the river Cam, and the Group maintains these 
various ecosystems for the benefit of a wide variety of flora and 
fauna including several endangered and protected species. The 
Group has previously commissioned ecology surveys to better 
understand the biodiversity on site. Tree surveys are undertaken 
periodically at both freehold sites, including during 2024, to 
assist proactive management. The Epsom property is Grade II 
listed within a parkland setting and in recent years the Group has 
undertaken significant repair and restoration work on the exterior 
stonework to preserve this historic building. 
ISO 14001
The CMS2 business holds ISO 14001 (Environmental Management 
Systems) certification to assist in managing the environmental 
impact of its manufacturing operations at the Group’s 
Portsmouth site. 
Sustainability services
In the Consultancy Division the number of projects either 
wholly related to sustainability or for which this was a major 
consideration continues to grow. The division leverages its 
broad scientific, commercial and regulatory expertise to develop 
sustainability strategies and provide sustainable solutions for 
clients across a wide range of industries. 
In the R&D Consultancy and Regulatory & Compliance 
businesses services cover a wide range of sustainability areas 
such as circularity, sustainable sourcing, emissions reduction, 
environmental impact, and regulatory impact and compliance. 
In the TPG Services business, the Osprey business advises on 
the impact of proposed wind and solar farms on aviation safety 
and associated mitigations in the planning consent process for 
renewable energy developments. 
Since 2021 the Group has convened and chaired a high level 
discussion forum with Chief Technology Officers and R&D leaders 
from major US and European blue chip companies. Originally 
focussed on net zero strategy and practice, in 2022 and 2023 the 
focus shifted to sustainability and, latterly, sustainability combined 
with growth. As a consequence, during 2024 the Group Managing 
Director together with other members of the forum contributed 
to the United Nations General Assembly’s Science Summit held in 
New York. 
Compliance
The Group’s operations are conducted in compliance with relevant 
environmental legislation. There were no internal or external 
environmental incidents during 2024 at any Group site and 
Science Group did not incur any fines.

STRATEGIC REPORT

Climate-Related Financial Disclosures 
 
This is Science Group’s second year of reporting pursuant to 
sections 414CA and 414CB of the Companies Act 2006. These 
disclosures align with the recommendations issued by the 
international Task Force on Climate-related Financial Disclosures 
(‘TCFD’). This statement covers Science Group’s governance of 
climate change, its integration with overall risk management, the 
identification and strategy for managing the Group’s climate-
related issues and opportunities, and the metrics used to measure 
progress. 
Governance
The Board has overall responsibility for sustainability issues 
including the oversight of climate-related matters and effective 
management of climate-related risks and opportunities, in 
line with the responsibility to monitor any issues which impact 
strategy, risk management, and operations of the Group. For more 
information on the Board and Board Committees see the Report 
of the Directors on page 23. The Board discussed climate-related 
issues and the Group’s TCFD-aligned reporting twice during 2024 
and was ultimately responsible for approving the Group’s climate-
related financial disclosures. To date it has not been deemed 
necessary to nominate an individual Board member to oversee 
climate-related issues due to the small size of the Board which 
ensures sufficient accountability. 
Science Group has a small Executive management team and all 
members have responsibility for the management of overall risks 
and climate change strategy across the Group. The Executive 
team stays in close contact with the Managing Directors to ensure 
they are up to date with any risks to the Group. The Company 
Secretary has been appointed to formalise the feeding of any 
strategy changes to the individual businesses and ensure they are 
carrying out specified initiatives against the strategy. Progress is 
then reported back to the Board by the Company Secretary. 
Based on the assessment of climate-related risks and 
opportunities and exposure being at the lower end of scale, as 
discussed in the Strategy section below, the Board believes there 
is sufficient expertise to manage climate-related matters at the 
Board and management levels. Where appropriate, external 
consultants may be engaged to advise further.
Risk management
During 2023 Science Group undertook a formal exercise 
to identify and assess the Group’s climate-related risks and 
opportunities with the support of sustainability consultants. 
Identified climate-related risks and opportunities were assessed 
using the Group’s existing risk management framework to 
integrate them with the Group’s wider business risks and to 
enable the significance of climate-related risks relative to these 
wider Group risks to be determined. These risks and opportunities 
were re-reviewed during 2024 and no significant changes were 
identified. 
While Science Group’s risk assessment is standardised across 
the Group, risks may be unique to different businesses. The 
Managing Directors report weekly to the Executive management 
team on business performance and any significant issues and 
provide formal reports to the full Board on a monthly basis. This 
ensures that potential emerging risks identified on the ground are 
escalated to the Board in a timely manner. Externally, the Group’s 
professional advisors raise relevant potential issues from time 
to time. 
Identified potential risks are discussed by the Executive 
management team. Both the impact (on a five point scale from 
Minor to Catastrophic based on financial loss exposure) and 
likelihood (on a five point scale from Rare to Very High) of the risks 
are assessed and an overall risk rating (on a three point scale from 
Green to Red) is determined which allows for the prioritisation of 
risks. A mitigation response (avoid, transfer, reduce or accept) is 
then determined as required. 
The Group has assessed climate-related risks and opportunities 
against the following defined time horizons:
Short term
1 to 3 years
In line with specific business 
plans and the Group’s viability 
statement
Medium term
3 to 10 years
In line with the majority of the 
Group’s site lease terms, which 
are between 5-10 years in 
remaining duration
Long term
More than 
10 years
Long enough to encompass 
long-term industry and policy 
trends, such as UK Net Zero 
2050 and for climate-related 
risks to manifest
In the Group’s climate-related risk assessment, all risk and 
opportunity categories outlined in the TCFD guidance have been 
considered. Risks have been assessed in relation to the Group’s 
own operations, supply chain and downstream. Not all risk 
categories are applicable or material to the business.
The Group’s climate-related risks are included in the risk register 
which was reviewed and approved by the Board during the 
year. Where appropriate, identified risks may also be assigned 
to a working party to keep a watching brief and update the 
Board as appropriate, although this was not deemed necessary 
during 2024.
Strategy
As a science and technology business primarily providing 
consultancy services, Science Group is at the lower end of 
exposure for climate-related risks. Based on the risk exposure 
after mitigation outlined in this statement, the Board believes that 
the Group is resilient to climate change and does not require a 
fundamental change to its strategy, financial planning or budgets. 
There are no effects of climate-related matters reflected in 
judgements and estimates applied in the financial statements. 
The key climate-related risks and opportunities for the Group are:
•	
Physical risks: As Science Group sites span the UK, Europe, US 
and Asia, and the Frontier business relies on manufacturing 
suppliers in Asia, the Group is currently exposed to physical 
risks that continue to persist into the long term. Adequate 
mitigation strategies including, where practicable, considering 
climate factors when choosing sites and diversifying suppliers 
will assist the Group to withstand these potential physical 
risks. 
•	
	Transition risks: The Group provides services and systems to 
customers in a range of sectors including medical, defence, 
industrial and consumer. This adds complexity to the analysis 
as these customers face their own climate-related issues and 
reporting pressures on them could be passed to Science 
Group. Keeping abreast of reporting expectations will reduce 
this risk. 
•	
	Opportunities: Opportunities exist both operationally to 
reduce the Group’s scope 1 and 2 emissions and in the market 
to assist customers who need to adapt to climate change. 
Charitable donations 
Science Group focuses its charitable donations on organisations 
supporting people-related issues. During 2024 this primarily 
included donations to charities supporting health issues. The 
Group’s Charitable Donations Policy also supports the matching of 
funds raised by employees on a discretionary basis. 
Governance
The Board considers sound governance a critical component 
of Science Group’s success and the delivery of its strategy. 
Science Group has an effective and engaged Board, with a 
strong non-executive presence from diverse backgrounds and 
well-functioning governance committees. Through the Group’s 
compensation policies and variable components of employee 
remuneration, the Remuneration Committee seeks to ensure that 
Science Group’s values are reinforced in employee behaviour and 
that effective risk management is promoted.
The Board takes issues of governance seriously and seeks 
to ensure transparency and streamlined administration. The 
Directors bring a broad range of technical, commercial, business, 
accounting, audit and corporate finance expertise. Culturally, 
the Board demonstrates a high degree of integrity, fairness 
and non-discrimination and promotes these values through the 
organisation. For more information see the Corporate Governance 
Report on page 25.
Ethical business conduct 
The Board is committed to high standards of governance and 
ethics. The Group has a strong ethical culture and it is the Group’s 
policy to conduct all business in an honest and ethical manner. 
The Group’s Ethics Policy and other associated policies set out the 
standards of behaviour expected from all those working for or on 
behalf of the Group. 
Anti-bribery
Science Group has a zero tolerance approach to bribery 
and corruption. The Group’s Anti-Bribery Policy applies to all 
employees and the Group seeks to impose equivalent principles 
on suppliers and representatives. 
Modern slavery
In accordance with the requirements of the Modern Slavery Act 
2015, the Group publishes an annual statement setting out the 
steps taken to ensure that slavery and human trafficking are not 
present in the Group’s businesses and supply chains. A copy of the 
current statement, together with previous versions, can be found 
on the Investor information page of the Science Group website. 
Whistleblowing
The Group’s Whistleblowing Policy provides protection and 
support for whistleblowers raising a genuine concern. One of the 
Group’s Non-Executive Directors acts as the escalation contact for 
whistleblowing reports. 
Cyber and data security
Science Group proactively manages the security of its IT networks 
and the confidential and sensitive data held by the Group. The 
Group has documented Information Security, IT and data privacy 
policies and implements regular cyber awareness training for all 
staff, test phishing campaigns and penetration testing. Businesses 
operating in the defence industry are subject to heightened 
monitoring of cyber threats, and the associated IT networks 
hold ISO 27001 (Information Security Management) and Cyber 
Essentials Plus certifications and other accreditations.
During 2024 the Group developed a Generative AI policy to 
provide a framework for the control and assessment of the use 
of Generative AI tools and use cases within the Group to ensure, 
among other things, appropriate IT security protections. 
Health and safety 
Science Group is committed to the health and safety of its 
employees, customers, sub-contractors and others who may be 
affected by the Group’s activities. The Group evaluates the risks 
to health and safety in the business and manages this through its 
Health and Safety Management Systems. The Group’s Health and 
Safety at Work policies are reviewed and updated regularly. 
The Board Executive Director responsible for health and safety is 
the Group Finance Director with day to day responsibility being 
undertaken by the Company Secretary. The Directors receive 
monthly health and safety reports covering all sites which include 
updates on safety incidents across the Group. 
The Group’s largest sites (Cambridge, Epsom and Portsmouth) 
have dedicated Health and Safety Committees that meet quarterly. 
Laboratory and manufacturing areas are subject to monthly 
inspections by competent reviewers and the results are reported 
on a monthly basis to the Board. Access to laboratory and test 
facilities is electronically controlled with permissions reviewed on a 
regular basis. The Portsmouth site holds ISO 45001 (Occupational 
Health and Safety Management) certification. 
The Group provides necessary information, instruction, training 
and supervision to ensure that employees are able to discharge 
their duties effectively. The Health and Safety Management 
Systems ensure compliance with applicable legal and regulatory 
requirements and internal standards and seeks, by continuous 
improvement, to develop health and safety performance.
Supplier management process 
The Group operates a supplier management process to ensure 
Executive management review of proposals to engage new large 
or business critical suppliers. 
Administrative rationalisation 
The Group regularly reviews and closes dormant legal entities 
to reduce administrative costs. During 2024 two entities were 
dissolved and some administrative functions were integrated 
across the Consultancy Division to improve operational efficiencies 
and governance. The Group also rationalises its property portfolio 
where appropriate to reduce overheads and increase efficiencies.

Risk 2: Flood & heat disruption in supply chain 
Physical climate-related risks could impact the Group’s suppliers. 
Some components used in the Frontier business are specialised 
and supply cannot easily be switched out for alternatives. 
Therefore, weather disruption to suppliers in this business could 
severely impact the supply chain and the Group’s ability to fulfil 
customer contracts. 
The Frontier business uses seven key suppliers across nine sites 
for the supply of components, outsourced manufacturing and 
logistics. These sites are located in mainland China, Hong Kong, 
South Korea, Singapore and the Philippines and have been 
assessed for physical climate-related risks as follows:
•	
There is a high risk of heat stress for four supplier sites 
which continues under the RCP 8.5 scenario for 2030, 
2050 and 2100 and for one supplier site under the RCP 8.5 
scenario for 2100 (the latter being a logistics provider for 
which alternatives are readily available). This is expected 
be a limited risk as staff are not working outside. During 
the year, Frontier sought to engage with these suppliers to 
understand any issues associated with the risk of heat stress 
and their potential mitigations but has been unable to obtain 
detailed information. Any new information received will be 
kept under review. All nine of the supplier sites (three being 
logistics providers) have a high precipitation stress risk which 
continues under the RCP 8.5 scenario for 2030, 2050 and 
2100. As the risk is already high and the suppliers have been 
able to operate under these conditions, it is assumed that the 
risk is manageable. Similarly, the tropical cyclone risk for two 
supplier sites is already high and appears manageable.
•	
Three supplier sites (two being logistics providers) have 
current high or extreme flood risk. During the year Frontier 
sought to investigate the potential impacts of floods on these 
suppliers and understand what safeguards they have in place, 
but has been unable to obtain detailed information. Any new 
information received will be kept under review.
•	
The analysis of supplier sites also investigated fire stress, sea 
level rise and drought stress of which there was no impact. 
The Frontier business contributed approximately 11% of the 
Group’s revenue in 2024 and disruption in the supply chain could 
result in serious loss if not mitigated. While options for alternative 
suppliers in the region which are not impacted by similar risks may 
be limited, these are kept under review.

Group-wide
The following two climate-related scenarios, published by the 
International Energy Agency (‘IEA’), have been used to assess the 
Group’s transition risks: 
A.	
Net Zero 2050 (‘NZE’): an ambitious scenario which sets out a 
pathway for the global energy sector to achieve net zero CO2 
emissions by 2050. 
B.	
Stated Policies Scenario (‘STEPS’): a scenario which represents 
the roll forward of already announced policy measures. This 
scenario outlines a combination of physical and transitions 
risk impacts as temperatures rise by around 2.5°C by 2100 
from pre-industrial levels, with a 50% probability. This 
scenario is included as it represents a base case pathway with 
a trajectory implied by today’s policy settings.
Risk 3: Carbon pricing in operations & value chain
For the Group’s operational emissions (scope 1 and 2), carbon 
pricing risks represent a risk of higher energy prices. For the 
Group’s principal value chain (upstream scope 3) emissions, 
carbon pricing mechanisms could result in higher costs of 
purchased goods or in-bound transportation. 
The IEA forecasts that carbon prices (US$/tCO2e) relevant to the 
Group are projected to increase from $140/t in 2030 to $250/t in 
2050 under the NZE scenario and from $90/t in 2030 to $113/t 
in 2050 under the STEPS scenario. The impact of this has been 
assessed as follows:
•	
Scope 1 and 2 emissions: The forecast carbon prices have 
a minor impact in both the NZE and STEPS scenarios when 
applied to the Group’s reported operational emissions for 
2024 (see the Energy and greenhouse gas (‘GHG’) reporting 
section on page 13). This does not take account of any future 
mitigation actions or material changes to the business and 
assumes that the full impact of carbon prices is passed onto 
the Group. 
•	
	Scope 3 emissions: This is the second year of the Group’s 
reporting on its emissions and energy usage and the 
reporting includes limited scope 3 emissions (see the Energy 
and greenhouse gas (‘GHG’) reporting section on page 13). 
Since the Group’s full scope 3 emissions footprint has not yet 
been calculated, the full financial impact of the forecast carbon 
prices cannot be assessed at this stage. It is also uncertain 
how and when carbon prices will be imposed in the value 
chain and how much will be passed on to the Group. However, 
the Group’s current view is that the impact of carbon pricing 
in the value chain is likely to be minor. As the sophistication of 
the Group’s scope 3 emissions reporting increases, a clearer 
insight will develop into the impact on the Group and how this 
may be mitigated. 
Given its nature, there is limited scope for the Group to manage 
this risk but it will be kept under review.
Other risks and opportunities have been assessed according 
to the TCFD guidance including increased costs for critical raw 
materials, technological redundancy of equipment, reputational 
risk due to projects in high environmental impact sectors and 
products that reduce energy usage. However, these have been 
deemed to be immaterial to the Group. 
Science Group will continue to develop its analysis as new data 
becomes available, both internally and externally, and will continue 
to monitor climate exposures and action plans through the 
Group’s risk management framework. Details of the physical and 
transition risks and opportunities identified are outlined below.

CMS2 business – Portsmouth site
Frontier suppliers in Asia 
The Group’s site portfolio has been assessed for physical climate-
related risks using geospatial risk modelling software and it was 
determined that the overall risk is limited. The Group’s small 
office locations were excluded as, in the event of site-related or 
commuting-related disruption, relevant staff would be able to 
work from home limiting the loss of business productivity. 
Of the Group’s three largest sites (Cambridge, Epsom and 
Portsmouth), only the Portsmouth manufacturing site has any 
associated physical risks. 
The Intergovernmental Panel on Climate Change (‘IPCC’) 
has developed a suite of scenarios that represent the future 
pathways of carbon in the atmosphere. Each of these is titled as 
a Representative Concentration Pathway (‘RCP’). The following 
three IPCC climate-related scenarios have been used to assess the 
Group’s physical climate-related risks: 
A.	
RCP 2.6: a climate-positive pathway, likely to keep global 
temperature rise below 2°C by 2100. CO2 emissions start 
declining by 2020 and go to zero by 2100. 
B.	
RCP 4.5: an intermediate and probable baseline scenario, 
more likely than not to result in global temperature rise 
between 2°C and 3°C, by 2100 with a mean sea level rise 35% 
higher than that of RCP 2.6. Many plant and animal species 
will be unable to adapt to the effects of RCP 4.5 and higher 
RCPs. Emissions peak around 2040, then decline.
C.	
RCP 8.5: a bad case scenario where global temperatures rise 
between 4.1°C to 4.8°C by 2100. This scenario is included for 
its extreme impacts on physical climate risks as the global 
response to mitigating climate change is limited. 
Risk 1: Storm and flood disruption
The Group’s Portsmouth site is the manufacturing facility for 
the CMS2 business and includes an industrial unit with a large 
factory floor located in the middle of a commercial estate. The 
site is currently subject to extreme exposure risk to flood due to 
a 1 in 100 years storm surge risk and an extreme risk of sea level 
rise under the RCP 8.5 scenario in 2100, and therefore the risk of 
flooding continues into the future. The Group is not aware of any 
incidents or insurance claims related to such events during the 
last 10 years. Floods can be difficult to predict so this risk will be 
actively monitored. The risk is well known and Portsmouth Council 
is investing to improve sea defences which will assist in protecting 
the Portsmouth site into the longer term. 
The CMS2 business contributed approximately 23% of the Group’s 
revenue in 2024. Although disruption from weather events may 
be covered by insurance, any requirement for the business to 
move locations, an inability to operate at full capacity or a lack of 
manufacturing equipment and facilities could result in significant 
delays to fulfilling customer contracts and possible damage to 
CMS2’s reputation. CMS2 has a long track record and a strong 
market position which may protect the division from customer 
switching although this could change in the longer term. Two 
servers are housed at the Portsmouth site. The risk of disruption 
to the CMS2 business’s IT infrastructure as a result of flooding is 
mitigated by daily back ups both locally and to servers at another 
Group site. 
The Board has considered mitigating the risk of storm and flood 
disruption more broadly by relocating the manufacturing facility 
to higher ground. However, the existing site lease continues until 
2033 and it would cost an estimated £4.5-£5.0 million to relocate 
now (including ongoing existing lease costs as well as rental and 
fit out costs for a new site). The Board does not consider this to be 
an economically viable option given the size of the CMS2 business 
and the cost and likelihood of the current climate-related risk. 
When the existing lease expires the Board currently expects to 
relocate the CMS2 business at that stage to mitigate the longer 
term risks. More generally, these risks are mitigated by the Group’s 
insurance policies which include cover for property damage and 
business interruption.

Risk 4: Reputational risk linked to sustainability  
performance & reporting
There is an increasing trend of investors incorporating 
sustainability criteria into their assessments. The Group has not 
experienced adverse investor interaction on climate change to 
date although ESG has been a topic of discussion with some 
investors. The Group’s bank loan and debt facilities are not tied to 
sustainability criteria and no negative feedback has been received 
from the Group’s banks. 
The Consultancy Division sees some customer’s incorporating 
climate-related and other ESG topics into supplier questionnaires 
although this has had no significant impact to date. 
There are limited opportunities to mitigate this risk but the Group 
will keep sustainability performance and reporting under close 
review.

Opportunity 1: Market opportunities 
It is anticipated that demand for sustainability-related services 
will grow as customers continue to adapt to climate change 
and mitigate their climate risks. Science Group’s cross-divisional 
sustainability practice seeks to take advantage of this opportunity 
by supporting customers with management and strategy services, 
sustainable innovation and product stewardship. The Group 
has seen an increased focus on sustainability in both the R&D 
Consultancy business, which supports customers’ exploration of 
possible scientific and technological solutions to climate-related 
challenges, and the Regulatory & Compliance business where 
sustainability concerns are driving a desire to reduce chemical 
usage and identify less harmful alternatives. For more information 
see the Sustainability services section on page 14. 
Opportunity 2: Operational opportunities
The Group has already implemented many renewable energy and 
energy reduction initiatives in its offices (see the Energy efficiency 
section on page 14). Similarly, water consumption and waste have 
a minimal impact as the majority of the Group’s sites are offices. 
However, there is still opportunity for incremental improvements 
to resource efficiencies and these will continue to be explored. The 
CMS2 manufacturing site in Portsmouth has not yet been formally 
assessed for energy reductions and may represent the greatest 
opportunity in this area.
Non-Financial and Sustainability Information Statement continued
Metrics and Targets
The Board does not consider that climate-related risks currently 
pose a significant risk to the Group’s business. However, during 
2024 the Group considered appropriate metrics to track 
identified climate-related risks and opportunities. Initial metrics 
to be tracked are set out below. At present the Group has not 
established targets associated with these metrics. 
Climate-related risk/opportunity
Metric
Opportunity: reduction of energy 
usage at UK sites
Assessment of energy 
usage and emissions 
(‘SECR’)
Opportunity: provision of 
sustainability-related consultancy 
services
Revenue generated from 
relevant projects
The Group will continue to review its metrics, and any potential 
targets, on an annual basis and may adapt these metrics or adopt 
new metrics and/or targets as its governance and assessment of 
climate-related risks and opportunities evolves. 
The Group reports on its scope 1, 2 and limited scope 3 emissions 
for the second time for the year ended 31 December 2024. This 
is included in the Energy and greenhouse gas (‘GHG’) reporting 
section on page 13. Science Group recognises the requirements 
of all businesses to contribute to the UK’s 2050 net zero 
ambitions. While in its first year of SECR reporting, the Group 
reported on the mandatory scope 3 emissions, the Group has 
built on this as its data collection and reporting processes evolve 
and flight emissions data is therefore included within scope 3 
reporting this year and in the restated 2023 assessment results. 
Science Group will continue to explore calculating additional scope 
3 emissions in future reports.

Purchase of own shares
At the AGM on 18 June 2024 shareholders approved a resolution 
for the Company to buy back up to 10% of its own shares. This 
resolution remains valid until the conclusion of the next Annual 
General Meeting in 2025 or 30 June 2025 if earlier. As at the date 
of this report, the Company has bought back 1,096,794 shares 
pursuant to this authority. Throughout 2024 the Company bought 
back a total of 1,080,507 shares at a cost of £5.0 million pursuant 
to both the 2024 AGM authority and the equivalent authority 
approved at the 2023 AGM. The nominal value of the share 
purchased was £10,805. For further information refer to Note 22.
Since October 2024, the Company’s buyback programme has 
been delegated to Panmure Liberum Limited on a discretionary 
basis, based on parameters defined by the Board at certain 
windows.
Employees
The average number of persons, including Directors, employed 
by the Group and their remuneration is set out in Note 8 to the 
Financial Statements.
Statement on engagement with employees 
The Board recognises the importance of engagement with 
employees and considers the current balance of engagement to 
be appropriate and reasonable given the size of the Group. 
At a Group level, employees are provided with information on 
matters of concern to them through the Group’s intranets, 
human resources (‘HR’) policies, direct updates from the HR 
team, and formal and informal meetings with line managers 
and senior managers. Individual businesses manage their own 
internal communications delivered across a variety of channels 
as appropriate. These include regular town hall meetings and 
presentations where employees have the opportunity to ask 
questions. The Executive Directors contribute to business 
management team meetings and away days as appropriate. 
Executive Directors regularly visit UK sites to engage directly with 
local management teams and employees in person, and work 
closely with Managing Directors. Employee communications are 
also made by Executive Directors through direct all-employee 
emails and update presentations.
The Group also implements a range of practices, policies and 
procedures to enable effective engagement with employees 
including mentoring, training and development programmes, 
appraisal processes and the Group’s whistleblowing policy. 
Engagement with the Group’s strategy, performance and values 
is encouraged through reward payments made under the 
Group’s bonus and profit share schemes and other discretionary 
incentives and, for more senior grades, the award of share 
options.
Statement on engagement with customers, suppliers  
and others
Engagement with customers, suppliers and other stakeholders 
in the business is an important factor in ensuring the successful 
implementation of the Group’s strategy. 
Engagement with customers and suppliers usually takes place 
at an individual business and project level. Where appropriate, 
the relevant management teams engage with customers over 
long-term or strategic programmes of work to foster strong 
relationships and enable the Group to understand customers’ 
initiatives and priorities.
The development and maintaining of relationships with 
customers is taken into account in key account management, 
the development and improvement of service offerings, the 
ongoing review and strengthening of the Group’s Quality 
Assurance procedures, and the maintenance of ISO 9001 (Quality 
Management Systems), ISO 13485 (Quality Management Systems 
for Medical Devices) and ISO 17025 (Testing and Calibration 
Laboratories) certifications in relevant businesses. In relation to 
suppliers, the need for good business relationships is considered 
when reviewing key and critical supplier lists, inventory purchasing 
and supplier payment terms. 
Disabled persons 
The Company gives full and fair consideration to suitable 
applications for employment from disabled persons where a 
disabled person can adequately fulfil the requirements of the role. 
Where an employee of the Company becomes disabled during 
the course of their employment the Company would seek to 
arrange appropriate further training for the employee, and make 
reasonable adjustments to the employee’s working environment, 
where it is possible for the employee to continue fulfilling the 
requirements of their role. Employees with a disability are eligible 
to participate in career development opportunities across the 
Company including training and promotion opportunities.

Adoption of recognised corporate governance code
The Board has previously adopted the Financial Reporting 
Council’s UK Corporate Governance Code July 2018 which is 
applicable for the year ending 31 December 2024. With effect 
from 1 January 2025, the Company is operating pursuant to 
Financial Reporting Council’s UK Corporate Governance Code 
January 2024. The Company’s statement of compliance and 
associated disclosures are available on the Investor information 
pages of the Company’s website.
Board of Directors
At 31 December 2024 the Board comprised an Executive Chair 
(part-time), Group Managing Director, Group Finance Director, 
and two independent Non-Executive Directors. All Directors bring 
a wide range of skills and international experience to the Board. 
The Non-Executive Directors hold meetings without the Executive 
Chair, Group Managing Director and Group Finance Director 
present if appropriate.
The Executive Chair is primarily responsible for the working of the 
Board of Science Group plc and the Group corporate strategy. 
High-level strategic decisions are discussed and taken by the full 
Board. Investment decisions (above a de minimis level) are taken 
by the full Board. Operational decisions are taken by the Executive 
Board members, Managing Directors and other senior managers 
within the frameworks approved in the annual financial plan and 
Board-approved authorisation levels.
The Board met 20 times during 2024 (2023: 13). The Board 
regulations define a framework of high-level authorities that map 
the structure of delegation below Board level, as well as specifying 
issues which remain within the Board’s preserve. 
The Board typically holds ten regular meetings a year to consider 
a formal schedule of matters including the operating performance 
of the business and to review Science Group’s financial plan and 
business model. Other meetings are held on an ad hoc basis as 
the need arises.
Non-Executive Directors are appointed for a three year term after 
which their appointment may be extended by mutual agreement 
after due consideration by the Nomination Committee of the 
Board. In accordance with the Company’s Articles of Association, 
the longest serving Director (from their last appointment) must 
retire at each Annual General Meeting and each Director must 
retire in any three year period, so that over a three year period 
all Directors will have retired from the Board and been subject to 
shareholder re-election.
All Directors have access to the advice and services of the 
Company Secretary and other independent professional advisers 
as required. Non-Executive Directors have access to key members 
of staff and are entitled to attend management meetings in order 
to familiarise themselves with all aspects of Science Group.
It is the responsibility of the Executive Chair and the Company 
Secretary to ensure that Board members receive sufficient and 
timely information regarding corporate and business issues to 
enable them to discharge their duties.
Relations with shareholders
The Directors seek to establish and maintain a mutual 
understanding of objectives between Science Group and its major 
shareholders by meeting to discuss long-term issues and receive 
feedback, communicating regularly throughout the year and 
issuing trading or business updates as appropriate. 
Engagement with shareholders is primarily via trading updates 
and other important information through announcements made 
via a regulatory news service and the Science Group website. 
During 2024 the Company issued two trading updates in addition 
to the Preliminary and Interim Results statements. Regular 
updates are also made to the Investor section of the Science 
Group website. The 2023 annual report was made available to all 
shareholders together with the notice of the 2024 Annual General 
Meeting. All shareholders were invited to attend the AGM and had 
the opportunity to ask questions of the Directors. 
Remuneration strategy
Science Group operates in a competitive market. If Science 
Group is to compete successfully, it is essential that it attracts, 
develops and retains high quality staff. Remuneration policy has 
an important part to play in achieving this objective. Science 
Group aims to offer its staff a remuneration package which is 
both competitive in the relevant employment market and which 
reflects individual performance and contribution. For 2024, in 
addition to base salary, benefits included pension contributions, 
healthcare and life assurance benefits, Group bonus and profit 
share schemes, additional bonus schemes based on achievement 
of billed hours targets for certain businesses within the Group, 
a commission scheme for sales people and, where appropriate, 
share options.
Board Committees
The Board maintains three standing committees, being the Audit, 
Remuneration and Nomination Committees. The minutes of all 
sub-committees are circulated for review and consideration by 
all relevant Directors, supplemented when appropriate by oral 
reports from the Committee Chairs at Board meetings.
The Board does not conduct a formal performance evaluation of 
the Directors nor do the independent Non-Executive Directors 
formally appraise the Executive Chair. The Board conducts an 
annual internal evaluation of the Board and its committees, the 
results of which are reviewed and discussed by the Board. Due to 
the small size of the Board this annual evaluation, together with 
regular informal performance evaluations of Directors and the 
Executive Chair by the Board, is considered sufficient.
Audit Committee
The Audit Committee is chaired by Peter Bertram and comprises 
Peter Bertram and Susan Clement Davies. The Audit Committee 
met 4 times during 2024 (2023: 3). It considers the findings 
from the Company’s auditors and tax advisors. Further details 
on the Audit Committee are provided in the Report of the Audit 
Committee on page 27. 
Remuneration Committee
The Remuneration Committee is chaired by Susan Clement 
Davies and comprises Susan Clement Davies and Peter Bertram. 
The Remuneration Committee met 13 times during 2024 (2023: 
8). It may take advice from time to time from external advisers 
but did not do so in 2024. Further details on the Remuneration 
Committee are provided in the Report of the Remuneration 
Committee on page 26.

Report of the Remuneration Committee
The Remuneration Committee is chaired by Susan Clement Davies 
and comprises Susan Clement Davies and Peter Bertram.
The Remuneration Committee monitors the remuneration policies 
of Science Group to ensure that they are consistent with Science 
Group’s business objectives. Its terms of reference include 
the recommendation and execution of policy on Director and 
Executive management remuneration and for reporting decisions 
made to the Board. The Remuneration Committee determines 
the individual remuneration package of the Executive Chair and 
Executive Directors, and also reviews remuneration packages for 
all senior employees of Science Group. This responsibility includes 
pension rights and any other compensation payments including 
bonus and profit share payments and share option awards. The 
Remuneration Committee’s remuneration practices do not include 
engagement with employees regarding Executive remuneration. 
The Remuneration Committee recognises that incentivisation of 
staff is a key issue for Science Group, which depends on the skill 
of its people for its success. The Remuneration Committee seeks 
to incentivise employees by linking individual remuneration to 
individual performance and contribution, and to Science Group 
results. During the year, the Remuneration Committee approved 
grants of share options and confirmed Group profit related 
bonus and profit share schemes for the Company for 2024. The 
Remuneration Committee also approved a number of individual 
discretionary bonuses and a festive winter bonus of £200 per 
person. All such payments are pro-rated for part time staff and, 
where appropriate, localised for employees outside of the UK.
The aim of the Board and the Remuneration Committee is to 
maintain a policy that:
•	
establishes a remuneration structure that will attract, retain 
and motivate Executives, senior managers and other staff of 
appropriate calibre.
•	
rewards Executives and senior managers according to both 
individual and Group performance.
•	
establishes an appropriate balance between fixed and variable 
elements of total remuneration, with the performance-related 
element forming a potentially significant proportion of the 
total remuneration package.
•	
aligns the interests of Executives and senior managers with 
those of shareholders through the use of performance-related 
rewards and share options in Science Group.
From time to time the Remuneration may obtain market data 
and information as appropriate when making its comparisons 
and decisions and is sensitive to the wider perspective, including 
pay and employment conditions elsewhere in Science Group, 
especially when undertaking salary/remuneration reviews. 
The Company is not required to, and does not, engage with 
shareholders regarding its remuneration policy. The remuneration 
policies operated as intended during the year.
Employee remuneration can include the following elements:
•	
basic salary: normally reviewed annually and set to reflect 
market conditions, personal performance and benchmarks in 
comparable companies. A limited interim review is normally 
undertaken each year reflecting the accelerated progress 
that more junior grades may require as they rapidly gain 
experience.
•	
annual Group performance-related bonus or profit share: 
Executives, managers and eligible employees receive 
annual bonus or profit share payments related to company 
performance. The bonus scheme includes a claw back 
mechanism in certain circumstances. The Executive Chair 
does not participate in the Group annual performance-related 
bonus scheme but the Remuneration Committee may at its 
sole discretion award a bonus if appropriate.
•	
billed hours bonus: employees in certain businesses 
participate in additional bonus schemes based on 
achievement of billed hours targets.
•	
commission: some employees in sales roles participate 
in commission schemes based on revenue received from 
relevant sales. These employees are not eligible for the Group 
bonus or profit share schemes.
•	
benefits: benefits include medical insurance, income 
protection, life assurance and pension contributions. The 
Executive Chair does not receive these benefits.
•	
share options: share option grants are normally reviewed 
annually and granted on a discretionary basis by the 
Remuneration Committee. The Executive Chair has excluded 
himself from all such awards since 2010.
Full details of each Director’s remuneration package and their 
interests in shares and share options can be found in Note 9 to 
the Financial Statements. There are no elements of remuneration, 
other than basic earnings, which are treated as being pensionable.
Share option plans
The Company’s current unapproved Performance Share 
Plan (‘PSP’) was adopted by the Company and approved by 
shareholders in 2022 on broadly equivalent terms to its previous 
PSP. All options granted under a PSP scheme are issued at the 
nominal share price. The Remuneration Committee approves any 
options granted. 
Directors are entitled to participate in Science Group’s share 
option schemes. It is the policy of Science Group to grant share 
options to Executive Directors and key employees as a means of 
encouraging ownership and providing incentives for performance. 
Independent Non-Executive Directors do not participate in Science 
Group’s share option schemes. The only share options granted 
to the Executive Chair, which occurred in 2010, were specifically 
approved by shareholders and he excludes himself from annual 
awards.
Director contracts and remuneration
The Executive Directors have employment contracts that contain 
notice periods of six months. Non-Executive Directors’ service 
contracts may be terminated on three months’ notice. There are 
no additional financial provisions for termination.
The Executive Chair and Non-Executive Directors receive a fixed 
salary. The Executive Chair does not participate in the Group 
bonus scheme but, if appropriate, the Remuneration Committee 
may award a discretionary bonus. Remuneration of the Executive 
Directors (excluding the Executive Chair) follows a simple structure 
of base salary, bonus and long term incentives using share 
options, including under the Enhanced Executive Incentive (‘EEI’) 
addendum to the PSP plan that was approved by shareholders at 
the 2022 AGM. The Executive Chair is not formally excluded from 
the share option plan but has declined awards of share options 
since 2010.
The market price of the shares at 31 December 2024 was 453.0 
pence (2023: 392.0 pence). The highest and lowest price during 
the year was 492.0 pence and 373.0 pence respectively.
Report of the Audit Committee
The Audit Committee is chaired by Peter Bertram and comprises 
Peter Bertram and Susan Clement Davies. Other Directors and 
relevant senior managers attend by invitation.
The Audit Committee provides a mechanism through which the 
Board can maintain the integrity of the financial statements of 
Science Group (including financial reporting policies) and any 
formal announcements relating to Science Group’s financial 
performance, review Science Group’s internal financial controls 
and Science Group’s internal control and risk management 
systems, and make recommendations to the Board in relation 
to the appointment of the external auditor, their remuneration 
both for audit and non-audit work, the nature, scope and results 
of the audit and the cost effectiveness and the independence 
and objectivity of the auditors. The Group does not maintain 
a separate internal audit function but the Group finance team 
undertakes regular reviews of key controls and processes. A 
recommendation regarding the auditors is put to shareholders for 
their approval in general meetings.
Provision is made by the Audit Committee to meet the auditors 
at least twice a year including at least one meeting without any 
Executive Directors present.
Financial reporting and significant financial matters 
In carrying out its duties, the Audit Committee is required to 
assess whether suitable accounting policies have been adopted 
and to challenge the robustness of significant management 
judgements reflected in the financial results. This is performed 
through discussions at Audit Committee meetings where the 
Group Finance Director explains any changes to accounting 
policies and describes any significant management judgements 
made. In addition, the Audit Committee reviews the year end 
Report to the Audit Committee from the external auditors which 
details its work performed and findings from the annual audit.
During the year, the Audit Committee considered the following key 
financial matters in relation to the Group’s financial statements 
and disclosures, with input from the external auditor:
Going concern – The going concern assertion has a significant 
impact on the basis of preparation of the financial statements. 
The Audit Committee reviewed the business plan presented by 
management for the financial year ending 31 December 2024 
and considered the key assumptions made by management. The 
Audit Committee challenged management on the assumptions 
in the plan and consequently considered them appropriate. The 
Audit Committee received the business plan cash flow which 
covered the period to the end of June 2026 and considered the 
associated assumptions, which were concluded to be appropriate. 
The business plan also considered compliance with the banking 
covenants.
The Group Finance Director performed a sensitivity analysis 
to assess the amount of headroom available in the event of a 
downside event occurring. The analysis considered the likelihood 
of a scenario where covenants would be breached. The conclusion 
was that the Group would continue to have sufficient cash 
resources in order to meet its liabilities as they fall due.
Carrying value of goodwill and acquisition related intangible 
assets – The value of the goodwill and acquisition related 
intangible assets is supported by a value in use model prepared 
by management. This is based on cash flows extracted from the 
Group’s financial plan which has been approved by the Board. 
The Group Finance Director communicated the key assumptions 
within the value in use model and the Audit Committee concurred 
with management’s conclusion that the carrying value of these 
assets was fully supported.
Risk of fraud within revenue recognition – Revenue is the most 
material balance in the Consolidated Income Statement and 
accordingly there is a rebuttable presumption that there is a fraud 
risk surrounding revenue. There is presumed to be an incentive 
to manipulate revenue in a manner that inflates the group profit, 
particularly around the year-end period. The risk is higher for 
those businesses which undertake fixed price work, in particular 
the CMS2 and TPG Services businesses.
Project managers carefully monitor the revenue recognised 
against projects and are accountable for the progress of projects. 
The Group Finance Director reviews the revenue recognised and 
accrued income balances on a monthly basis and investigates any 
unusual amounts recognised against projects. Collectively these 
processes would identify any unwarranted revenue recognised. 
No instances of fraudulent revenue recognition have been noted 
from these monitoring procedures in the current year. In the 
event of any significant issues arising the Group Finance Director 
would raise with the Chair of the Audit Committee and the Board. 
Whilst the Audit Committee is satisfied with management’s 
response to the risk this incentive represents, the Committee 
provides regular challenge to the Executive Directors. The 
Audit Committee fully reviews the Auditor’s Report (particularly 
in relation to revenue matters) and seeks to ensure that any 
recommendations are quickly implemented and that subsequent 
compliance is monitored.

Recoverability of investments in subsidiaries of Science Group 
plc – The value of investments in subsidiaries is supported by a 
value in use model prepared by management. This was based 
on cash flows extracted from the Group’s financial plan which 
has been approved by the Board. The Group Finance Director 
communicated the key assumptions within the value in use 
model and the Audit Committee concurred with management’s 
conclusion that the carrying value of these assets was fully 
supported.
Internal controls
In applying the principle that the Board should maintain a sound 
system of internal control to safeguard shareholders’ investments 
and Science Group’s assets, the Directors recognise that they have 
overall responsibility for ensuring that Science Group maintains 
systems to provide them with reasonable assurance regarding 
effective and efficient operations, internal control and compliance 
with laws and regulations and for reviewing the effectiveness 
of that system. However, there are inherent limitations in any 
system of control and accordingly even the most effective system 
can provide only reasonable and not absolute assurance against 
material misstatement or loss. The system is designed to manage 
rather than eliminate the risk of failure to achieve the business 
objectives.
Science Group has established procedures necessary to 
implement the guidance on internal control issued by the FRC 
Guidance on Audit Committees 2014. This includes identification, 
categorisation and prioritisation of critical risks within the business 
and allocation of responsibility to its Executives and senior 
managers.
The key features of the internal control system are 
described below:
Control environment – Science Group is committed to high 
standards of business conduct and seeks to maintain these 
standards across all of its operations. There is a whistleblowing 
policy in place for the reporting and resolution of suspected 
fraudulent activities. There is a continual review of payment 
processes, authorisation levels for expenditure, and awareness 
raising of the risks of fraudulent activities. Science Group has 
an appropriate organisational structure for planning, executing, 
controlling and monitoring business operations in order to 
achieve its objectives.
Risk identification – Corporate and operational managers are 
responsible for the identification and evaluation of key risks 
applicable to their areas of business. These risks are assessed on 
a continual basis and may be associated with a variety of internal 
and external sources, including infringement of IP, sales channels, 
investment risk, staff retention, disruption in information systems, 
natural catastrophe and regulatory requirements.
Information systems – Group businesses participate in 
operational/strategy reviews and annual plans. The Board actively 
monitors performance against the financial plan. Forecasts and 
operational results are consolidated and presented to the Board 
on a regular basis. Through these mechanisms, performance is 
continually monitored, risks identified in a timely manner, their 
financial implications assessed, control procedures re-evaluated 
and corrective actions agreed and implemented.
Main control procedures – Science Group has implemented 
control procedures designed to ensure complete and accurate 
accounting for financial transactions and to limit the exposure to 
loss of assets and fraud. Measures taken include segregation of 
duties, as far as reasonably practicable.
Monitoring and corrective action – There are procedures in place 
for monitoring the system of internal financial controls.
This process, which operates in accordance with the FRC 
Guidance, was maintained throughout the financial year, and has 
remained in place up to the date of the approval of these financial 
statements. The Board, via the Audit Committee, has reviewed 
the systems and processes in place in meetings with the Group 
Finance Director and Science Group’s auditors during 2024. No 
internal audit function is operated outside of the systems and 
processes in place as the Board considers that Science Group is 
currently too small for a separate function, although this remains 
under regular review. The Board considers the internal control 
system to be appropriate for the Group.
Auditors
Grant Thornton UK LLP was reappointed at the AGM on 18 June 
2024. The Audit Committee considers the independence of the 
auditors as part of considering their annual reappointment.
During the year ended 31 December 2024, a Grant Thornton 
International member firm in Hong Kong provided low value tax 
compliance services to a subsidiary within the Group at a time 
when Grant Thornton International should not have provided any 
non-audit services. The Audit Committee is satisfied this was a 
one-off incident and Grant Thornton is not currently providing any 
other non-audit services. 
Report of the Nomination Committee
The Nomination Committee is chaired by Martyn Ratcliffe and 
comprises Martyn Ratcliffe, Peter Bertram and Susan Clement 
Davies.
The Nomination Committee’s primary function is to make 
recommendations to the Board on all new appointments and 
reappointments and also to advise generally on issues relating 
to Board composition and balance. The Committee seeks input 
from all Directors regarding nominations for Board positions. All 
Board appointments have to be ratified at a General Meeting of 
the Company.
The Nomination Committee does not believe that it is appropriate 
to set any specific targets with regards to diversity, including 
gender. The Committee believes that the search for Board 
candidates should be conducted, and appointments made, 
on merit, against objective criteria but with due regard for the 
benefits of diversity on the Board. Given the small size of the 
Board and infrequency of Board appointments, the Company does 
not have a fixed process for seeking new candidates. However, 
where appropriate, this may include appointing an external search 
agency to assist with recruitment.

Directors’ Responsibilities
The Directors are responsible for preparing the Annual Report 
and the Group and parent Company financial statements in 
accordance with applicable law and regulations. The Directors 
consider that the Annual Report and financial statements, taken 
as a whole, are fair, balanced and understandable, and provide 
the information necessary for shareholders to assess the Group’s 
position, performance, business model and strategy.
Company law requires the Directors to prepare Group and parent 
Company financial statements for each financial year. As required 
by the AIM Rules of the London Stock Exchange they are required 
to prepare the Group financial statements in accordance with 
International Financial Reporting Standards (‘IFRS’) as adopted by 
the UK and applicable law and have elected to prepare the parent 
Company financial statements on the same basis.
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 their 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 
and reliable.
•	
state whether they have been prepared in accordance with 
IFRS as adopted by the UK.
•	
assess the Group and parent Company’s ability to continue as 
a going concern, disclosing, as applicable, matters related to 
going concern.
•	
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 confirm that they consider it appropriate to 
adopt the going concern basis of accounting in preparing the 
Annual Report and financial statements.
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 
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 and a Directors’ 
Report 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.

Independent auditor’s report to the members of Science Group plc 
Our opinion on the financial statements is unmodified
We have audited the financial statements of Science Group plc (the ‘parent company’) and its subsidiaries (the ‘group’) for the year ended 
31 December 2024, which comprise the Consolidated Income Statement, the Consolidated Statement of Comprehensive Income, the 
Consolidated Statement of Changes in Shareholders’ Equity, Company Statement of Changes in Shareholders’ Equity, the Consolidated 
and Company Balance Sheets, the Consolidated and Company Statements of Cash Flows and Notes to the Financial Statements, 
including a summary of significant accounting policies. The financial reporting framework that has been applied in their preparation is 
applicable law and UK-adopted international accounting standards and, as regards the parent company financial statements, as applied 
in accordance with the provisions of the Companies Act 2006. 
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 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) (‘ISA’ (UK)) and applicable law. Our responsibilities under 
those standards are further described in the ‘Auditor’s responsibilities for the audit of the financial statements’ section of our report. We are 
independent of the group and the parent company in accordance with the ethical requirements that are relevant to our audit of the financial 
statements in the UK, including the FRC’s Ethical Standard as applied to listed entities, and we have fulfilled our other ethical responsibilities 
in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis 
for our opinion.
Other matters – Non-audit services provided by member forms
During the year ended 31 December 2024, a Grant Thornton International member firm in Hong Kong provided tax compliance services 
in May to August 2024, to a non-significant controlled undertaking of the group, which are prohibited in accordance with the Financial 
Reporting Council’s Ethical Standard. We identified these prohibited services through our audit procedures. Appropriate safeguards have 
been put in place to mitigate the impact these prohibited services would have had on our independence, such that we could conclude that 
these services were inconsequential to our audit of the group’s financial statements.
Conclusions relating to going concern
We are responsible for concluding on the appropriateness of the directors’ use of the going concern basis of accounting and, based on the 
audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the group’s 
and the parent company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw 
attention in our report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify the auditor’s 
opinion. Our conclusions are based on the audit evidence obtained up to the date of our report. However, future events or conditions may 
cause the group or the parent company to cease to continue as a going concern.
Our evaluation of the directors’ assessment of the group’s and the parent company’s ability to continue to adopt the going concern basis of 
accounting included:
•	
obtaining and assessing management’s paper and assessment of going concern, including forecasts covering the period to 30 June 2026 
and testing the mathematical accuracy of forecasts, as approved by the board;
•	
performing arithmetical accuracy procedures on each of management’s forecast scenarios, including forecast liquidity and covenant 
calculations;
•	
assessing the robustness and accuracy of forecasts prepared by comparison to forecasts made in prior periods, including assessing 
management’s historic ability to forecast, in light of our understanding of the group’s operations;
•	
assessing the reasonableness of the key assumptions applied in management’s forecasts by comparing to external market data and 
historic performance;
•	
assessing forecast compliance with financial covenants within the group’s facilities for the period to 30 June 2026, and assessing the 
headroom available to the group in the forecast period;
•	
assessing reverse stress tests performed by management and determining if they are plausible; 
•	
considering post balance sheet events, and their impact on management’s forecast scenarios; and
•	
assessing the appropriateness of disclosures in respect of going concern made in the financial statements.

Materiality
Key Audit
Matters
Scoping
Overall materiality: 
Group: £744,000 which represents 5.0% of the group’s profit 
before tax.
Parent company: £1,609,200, which represents 1.9% of the parent 
company’s net assets. 
Key audit matters were identified as: 
•	
Valuation of existing goodwill (group) and investments (parent 
company) (same as previous year); and
•	
Occurrence of revenue from fixed price over-time contracts in 
Critical Maritime Systems & Support Limited (‘CMS2’) and TPG 
Services Limited (‘TPG Services’) (same as previous year).
Our auditor’s report for the year ended 31 December 2023 included 
one key audit matter that has not been reported as a key audit 
matter in our current year’s report. This related to the valuation of 
acquired intangibles arising from the TP Group acquisition in early 
2023. Given the one-off nature of the transaction, we no longer 
consider this to be a key audit matter.
We performed audits of the financial information of 4 components 
using component performance materiality, and specified audit 
procedures on the financial information of 7 components, to gain 
sufficient appropriate audit evidence at group level. 
This gives a coverage of 83% of the group’s total revenue, and 70% of 
the group’s profit before tax.
We performed analytical procedures at group level using group 
materiality for all 9 other components of the group.
The type of work performed on components changed from the 
prior year. Due to changes in the composition of the group, we have 
increased our scope on one component from analytical procedures 
at group to specified audit procedures, and on one component from 
specified audit procedures to an audit of the component’s financial 
information.
In our evaluation of the directors’ conclusions, we considered the inherent risks associated with the  group’s and the parent company’s 
business model including effects arising from macro-economic uncertainties such as the conflicts in Ukraine and the Middle East, the recent 
inflationary environment, and the impact of recent US government economic policies.  We assessed and challenged the reasonableness of 
estimates made by the directors and the related disclosures and analysed how those risks might affect the group’s and the parent company’s 
financial resources or ability to continue operations over the going concern period.  
In auditing the financial statements, we have concluded that the directors’ use of the going concern basis of accounting in the preparation of 
the financial statements is appropriate. 
Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or 
collectively, may cast significant doubt on the group’s and the parent company’s ability to continue as a going concern for a period of at least 
twelve months from when the financial statements are authorised for issue.
Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report.

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

How our scope addressed the matter – Group and parent company
Valuation of existing goodwill (group) and investments 
(parent company) 
We identified the carrying value of goodwill, and the associated 
investment value in the parent company, as one of the most 
significant assessed risks of material misstatement due to fraud 
and error. 
We have pinpointed the significant risk in relation to the carrying 
value of goodwill (group) and investment (parent company) to 
the Frontier Smart Technologies CGU (‘Cash Generating Unit) and 
the TPG Services CGU. There is an incentive and opportunity to 
overstate the value of these CGUs due to their recent performance 
and their significance to the group.
This is due to there being significant judgement and uncertainty in 
management’s forecasted growth beyond 2024, and the headroom 
over the carrying value of the CGUs being more sensitive to 
changes in management’s assumptions regarding the future 
performance of the CGUs. 
Under International Accounting Standard (‘IAS’) 36 ‘Impairment 
of Assets’, management is required to assess at the end of each 
reporting period whether there is any indication that an asset may 
be impaired and to perform an annual assessment whether the 
group’s goodwill within a CGU is impaired. 
The process for assessing whether impairment of assets exists 
under IAS 36 is complex, and therefore required significant auditor 
attention. 
Management prepares models to calculate the value in use 
through forecasting cash flows relating to each CGU, applying 
an appropriate discount rate and, other assumptions. These are 
all highly judgemental and can therefore be subject to error. The 
selection of certain inputs into the cash flow forecasts can also 
significantly impact the results of the impairment assessment. 
In responding to the key audit matter, we performed the following 
audit procedures:
•	
Evaluated the design and implementation of relevant controls 
around the process of preparing an impairment assessment by 
performing a walkthrough;
•	
Tested the accuracy of management’s forecasting through a 
comparison of prior forecasts to actual data;
•	
Obtained management’s assessment over carrying value and value 
in use and assessed management’s identification of CGUs against 
the requirements of IAS 36;  
•	
Assessed the mathematical accuracy of the impairment model and 
the methodology applied by management for consistency with the 
requirements of IAS 36;
•	
Checked the consistency between the figures in the impairment 
model to the consolidated budget evaluated as part of our work 
performed on the going concern basis of preparation;
•	
Challenged management on their methods and assumptions 
including, but not limited to, short- and long-term growth rates, 
future profitability, discount rates, and capital expenditure and 
working capital assumptions, ensuring these are reasonable and 
supported by data. 
•	
Engaged our internal valuations team (auditor experts) to challenge 
the methodology and key assumptions used before forming an 
opinion on the weighted average cost of capital (‘WACC’) rates and 
long-term growth rates used in management’s model;
•	
Assessed the actual performance of the CGUs between the 
impairment assessment date and signing of the financial 
statements to understand the consistency or otherwise between 
post-assessment trading and management’s forecasts thereof;
•	
Assessed the sensitivities applied by management, and performed 
auditor sensitivities to understand the impact of any reasonably 
possible change in assumptions and evaluate the headroom 
available to assess whether goodwill or investment balances could 
be impaired; and
•	
Assessed the adequacy of the group’s disclosures, including a 
review of the plausible downside scenarios shown at Note 14 & 
16 with response to the carrying value of goodwill and investment 
held in the parent company.

Key Audit Matter – Group
How our scope addressed the matter – Group
Occurrence of revenue from fixed price over-time contracts in 
CMS2 and TPG Services 
We identified the occurrence of revenue arising from fixed price 
over-time contracts in CMS2 and TPG Services as one of the most 
significant assessed risks of material misstatement due to fraud 
and error.
Under ISA (UK) 240 there is a rebuttable presumed risk that revenue 
may be misstated due to the improper recognition of revenue. 
Revenue in CMS2 and TPG Services from over-time contracts 
totalled £33.4m in the period. We pinpointed the significant risk to 
contracts which exhibited certain qualitative and quantitative risk 
criteria. 
Management continues to apply the provisions of ‘IFRS’ 15 ‘Revenue 
from Contracts with Customers’. Revenue is recognised based on 
stage of completion measured in reference to costs incurred as a 
proportion of total costs (‘input method’). Stage of completion is 
therefore based on actual costs incurred to date over estimated 
costs to complete. 
The estimation of costs to complete is inherently complex and 
significant management judgment is required.  
In responding to the key audit matter, we performed the following 
audit procedures:
•	
Assessed the design effectiveness of controls in respect of 
revenue recognition by performing walkthroughs;
•	
Obtained managements accounting papers for those identified 
as high risk and review the revenue recognition against the 
identified contract terms;
•	
Performed substantive testing on those contracts assessing the 
appropriateness of revenue recognised in the year;
•	
Made inquiries of project managers to obtain an understanding 
of the performance of the contract throughout the period and at 
period end;
•	
Obtained comfort over accuracy of management’s forecasting, 
and completeness of forecast costs by:
–	
Obtaining evidence of milestones being met and checking 
whether costs to achieve milestone are in line with forecasts;
–	
Inquiring with project managers - to assess current status 
of open projects and to identify whether there have been 
any significant changes in budget, and whether they expect 
remaining costs to be in-line with forecasts post year-end.
–	
Assessing post year-end costs incurred and updated 
forecasts; and
–	
Assessing the group’s historical forecasting accuracy by 
comparing prior estimated costs to complete to actual costs 
incurred and actual margin achieved when the contracts were 
completed during the current period;
•	
Assessed the treatment of liquidated damages, or similar 
contract terms, for the sample of contracts reviewed to determine 
whether any required constraint of variable consideration had 
been applied;
•	
Recalculate a sample of accrued and deferred income to 
determine whether any revenue accruals and deferrals have been 
appropriately made;
•	
In addressing the significant risk on manipulation of project costs 
we have performed a journals procedure to test the re-allocation 
of costs between project codes;
•	
Tested a sample of costs incurred to corroborative support such 
as purchase orders, subcontractor agreements, good received 
notes and purchase invoices, as appropriate, to determine if 
these were valid project costs, allocated to the correct project, 
and that the value of revenue recognised was therefore 
appropriate in relation to the stage of completion; and
•	
Assessed the accounting policy and adequacy of the disclosures 
against the requirements of IFRS 15, and the disclosure made 
in respect of key judgments and estimates involved in long term 
contract accounting.

Our results
Our audit procedures did not identify any material misstatements 
related to the occurrence of revenue from fixed price over-time 
contracts in CMS2 and TPG Services. 
Our application of materiality
We apply the concept of materiality both in planning and performing the audit, and in evaluating the effect of identified misstatements on 
the audit and of uncorrected misstatements, if any, on the financial statements and in forming the opinion in the auditor’s report.
Materiality was determined as follows:
Materiality measure
Group
Parent Company
Materiality for financial statements 
as a whole
We define materiality as the magnitude of misstatement in the financial statements that, 
individually or in the aggregate, could reasonably be expected to influence the economic decisions 
of the users of these financial statements. We use materiality in determining the nature, timing and 
extent of our audit work.
Materiality threshold
£744,000 (2023: £619,000), which represents 
5.0% (2023: 5.0%) of profit before tax.
£1,609,200 (2023: £557,100), which represents 
1.9% (2023: 0.7%) of the parent company’s net 
assets. 
Significant judgements made by 
auditor in determining  materiality
In determining materiality, we made the 
following significant judgements: 
•	
We have selected profit before tax as the 
most appropriate benchmark because the 
group is a commercially focused organisation 
and profit before tax is a key financial 
measure for the shareholders, and is a 
generally accepted audit benchmark.
•	
A performance-based measurement 
percentage of 5.0% was chosen, which 
reflects our knowledge of the business 
from prior audits, and aligns with our firm’s 
methodology.
Materiality for the current year is higher than 
the level that we determined for the year ended 
31 December 2023 to reflect the higher profit 
before tax in the year.
In determining materiality, we made the 
following significant judgements:
•	
We have selected net assets as the most 
appropriate benchmark as the parent 
company is a non-trading entity, and holds 
investments in other group trading entities.
•	
1.9% was considered to be an appropriate 
percentage based on our knowledge of the 
business from prior year audits and aligns 
with our firm’s methodology as applied in the 
financial year under audit. 
•	
For group audit purposes, we capped 
materiality at 55% of group materiality based 
on the component’s significance within 
the group, as the materiality based on net 
assets was higher than group performance 
materiality. 
Performance materiality used to 
drive the extent of our testing
We set performance materiality at an amount less than materiality for the financial statements as a 
whole to reduce to an appropriately low level the probability that the aggregate of uncorrected and 
undetected misstatements exceeds materiality for the financial statements as a whole.
Performance materiality threshold
£558,000 (2023: £433,300), which is 75% (2023: 
70%) of financial statement materiality.
The range of component performance 
materialities used across the group was 
£279,000 to £391,000.
£1,206,750 (2023: £389,970), which is 75% (2023: 
70%) of financial statement materiality. Parent 
company component performance materiality 
has been capped at an amount less than 
group performance materiality for group audit 
purposes. 
Significant judgements made by 
auditor in determining performance 
materiality
In determining performance materiality, we 
made the following significant judgements:
•	
Whether there were any significant 
adjustments made to the group financial 
statements in prior years; and
•	
Whether there were any significant control 
deficiencies identified in prior years.
In determining component performance 
materiality, we made the following significant 
judgements:
•	
Extent of disaggregation of financial 
information across components, including 
the relative risk and size of a component to 
the group.
For each component in scope for our group 
audit, we allocated a performance materiality 
that is less than our overall group performance 
materiality. 
In determining performance materiality, we 
made the following significant judgements:
•	
Whether there were any significant 
adjustments made to the group financial 
statements in prior years; and
•	
Whether there were any significant control 
deficiencies identified in prior years.

Specific materiality
We determine specific materiality for one or more particular classes of transactions, account

statements as a whole could reasonably be expected to influence the economic decisions of users 
taken on the basis of the financial statements.

Communication of misstatements 
to the audit committee
We determine a threshold for reporting unadjusted differences to the audit committee.
Threshold for communication
£37,200 (2023: £30,950), which represents 
5% of financial statement materiality, and 
misstatements below that threshold that, in our 
view, warrant reporting on qualitative grounds.
£80,500 (2023: £27,800), which represents

materiality and the threshold for communication to the audit committee.

Overall materiality – Parent 
An overview of the scope of our audit
We performed a risk-based audit that requires an understanding of the group’s and the parent company’s business and in particular matters 
related to:
Understanding the group, its components, their environments, and its system of internal control including common controls
We obtained an understanding of the group and its environment, including group-wide controls and IT general controls; and assessed the 
risks of material misstatement at a group level.
All financial reporting is based in the UK. Each division has an accounting function which reports to the divisional management in addition to 
the group finance team. 
In assessing the risk of material misstatement of the group financial statements, we considered the transactions undertaken by each entity 
and therefore where the focus of our work was required.
Identifying components at which to perform audit procedures
We identified components at which to perform further audit procedures by considering: 
•	
components which included an individual risk of material misstatement to the group financial statements; this included considering the 
nature of the individual components and circumstances during the period. Individual risks of material misstatement included, but were 
not limited to, revenue recognition where revenue is recognised over time, occurrence and accuracy of revenue, valuation of goodwill 
and management override of controls;
•	
components which contained a nature and/or size of classes of transactions, account balances or disclosures which were deemed 
material to the group opinion.
In addition, components were identified for further audit procedures to obtain sufficient appropriate audit evidence for significant classes of 
transactions, account balances and disclosures, or for unpredictability. 
Type of work to be performed on financial information of parent and other components (including how it addressed the key audit matters)
We performed audits of the component financial information for Sagentia Limited, Frontier Smart Technologies Limited, TPG Services Limited 
and Critical Maritime Systems & Support Limited. These audits of component financial information included all of our audit work on the 
identified key audit matters as described above. 
Specified audit procedures were performed on the financial information of the following components: Science Group Plc, Quadro Epsom 
Limited, Quadro Harston Limited, Leatherhead Research Limited, Technology Sciences Group Consulting Limited, Technology Sciences Group 
Inc and Osprey Consulting Services Limited.
Analytical procedures were performed on the financial information of all other components using group materiality.
Performance of our audit
During our audit, all audit procedures over full-scope audits, specified audit procedures and analytical procedures, were performed by the 
group engagement team, and the use of staff from Grant Thornton International Limited member firms to observe physical stock counts at 
overseas locations. Onsite visits were made to United Kingdom based sites by the group engagement team throughout the audit process. 
The group has a set of centralised controls, performed by the group finance team based in the UK. We have assessed the design and 
implementation of group wide controls, acquiring corroborating evidence of the process. Additionally, we have obtained a sufficient 
understanding of relevant controls over their consolidation process, and IT environment for in-scope components. All components subject to 
audit procedures report in the UK.
Further audit procedures performed on components subject to specific scope and specified procedures may not have included testing of all 
significant account balances of such components, but further audit procedures were performed on specific accounts within that component 
that we, the group auditor, considered had the potential for the greatest impact on the group financial statements either due to risk, size or 
coverage. 
The components within the scope of further audit procedures accounted for the following percentages of the group’s results, including the

Changes in approach from previous period
The approach to the audit has changed from the previous year. An audit of component financial information has been performed for Frontier 
Smart Technologies Limited due to their share of revenue and profit before tax within the group. We have changed the level of our audit 
procedures on Osprey Consulting Services Limited from analytical procedures performed at group level to specified audit procedures to 
ensure sufficient testing coverage across the group. The scoping on TP Group Limited has changed from specified audit procedures to 
analytical procedures performed at a group level as this component is no longer of a specific nature or size in the context of the group as 
a whole. One component was dissolved in the year, reducing the number of components subject to analytical procedures performed at a 
group level.

Independent auditor’s report to the members of Science Group plc continued
Other information
The other information comprises the information included in the annual report, other than the financial statements and our auditor’s report 
thereon. The directors are responsible for the other information contained within the annual report. Our opinion on the financial statements 
does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of 
assurance conclusion thereon. 
Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent 
with the financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If we identify such 
material inconsistencies or apparent material misstatements, we are required to determine whether there is a material misstatement in the 
financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other 
information, we are required to report that fact. 
We have nothing to report in this regard.
Our opinion on other matters prescribed by the Companies Act 2006 is unmodified
In our opinion, based on the work undertaken in the course of the audit:
•	
the information given in the strategic report and the directors’ report for the financial year for which the financial statements are 
prepared is consistent with the financial statements; and
•	
the strategic report and the directors’ report have been prepared in accordance with applicable legal requirements.
Matter on which we are required to report under the Companies Act 2006
In the light of the knowledge and understanding of the group and the parent company and their environment obtained in the course of the 
audit, we have not identified material misstatements in the strategic report or the directors’ report. 
Matters on which we are required to report by exception
We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us 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 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. 
Corporate governance statement
We have reviewed the directors’ statement in relation to going concern, longer-term viability and that part of the Corporate Governance 
Statement relating to the group’s compliance with the provisions of the UK Corporate Governance Code specified for our review by the 
Listing Rules.
Based on the work undertaken as part of our audit, we have concluded that each of the following elements of the Corporate Governance 
Statement is materially consistent with the financial statements or our knowledge obtained during the audit:
•	
the directors’ statement with regards to the appropriateness of adopting the going concern basis of accounting and any material 
uncertainties identified;
•	
the directors’ explanation as to their assessment of the group’s prospects, the period this assessment covers and why the period is 
appropriate;
•	
the director’s statement on whether they have a reasonable expectation that the group will be able to continue in operation and meet its 
liabilities;
•	
the directors’ statement on fair, balanced and understandable; 
•	
the board’s confirmation that it has carried out a robust assessment of the emerging and principal risks;
•	
the section of the annual report that describes the review of the effectiveness of risk management and internal control systems; and
•	
the section describing the work of the audit committee.
Responsibilities of directors
As explained more fully in the directors’ responsibilities statement set out on page 29, the directors are responsible for the preparation of 
the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine is 
necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.
In preparing the financial statements, the directors are responsible for assessing the group’s and the parent company’s ability to continue 
as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the 
directors either intend to liquidate the group or the parent company or to cease operations, or have no realistic alternative but to do so.
Auditor’s responsibilities for the audit of the financial statements
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, 
whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, 
but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. 
Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be 
expected to influence the economic decisions of users taken on the basis of these financial statements.
Irregularities, including fraud, are instances of non-compliance with laws and regulations. The extent to which our procedures are capable of 
detecting irregularities, including fraud, is detailed below: 
•	
We obtained an understanding of the legal and regulatory frameworks applicable to the parent company and the group and industry in 
which they operate. We determined that the following laws and regulations were most significant: UK-adopted international accounting 
standards, the Companies Act 2006, the UK Corporate Governance Code 2018 and the relevant tax compliance regulations in the 
jurisdictions in which the group operates; 
•	
We inquired of management, the finance team, legal counsel and the board of directors about the group’s and parent company’s policies 
and procedures relating to: 
–	
The identification, evaluation and compliance with laws and regulations; 
–	
The detection and response to risks of fraud; and 
–	
The establishment of internal controls to mitigate risks related to fraud or non-compliance with laws and regulations. 
•	
We obtained an understanding of the group’s policies and procedures implemented to prevent and detect non-compliance with laws 
and regulations by inquiry of management, those responsible for legal and compliance procedures including the company secretary. We 
corroborated our inquiries through our reading of board meeting minutes; 
•	
We assessed the susceptibility of the parent company’s and group’s financial statements to material misstatement, including how fraud 
might occur. Audit procedures performed by the group engagement team;
–	
identifying and assessing the design and implementation of controls management has in place to prevent and detect fraud and the 
adequacy of procedures for authorisation of transactions and internal review procedures; 
–	
challenging assumptions and judgements made by management in its significant accounting estimates, including utilisation of 
valuation specialists to review management’s impairment calculation; and 
–	
identifying and testing journal entries, in particular large or unusual journals
•	
These audit procedures were designed to provide reasonable assurance that the financial statements were free from fraud or error. The 
risk of not detecting a material misstatement due to fraud is higher than the risk of not detecting one resulting from error and detecting 
irregularities that result from fraud is inherently more difficult than detecting those that result from error, as fraud may involve collusion, 
deliberate concealment, forgery or intentional misrepresentations. Also, the further removed non-compliance with laws and regulations 
is from events and transactions reflected in the financial statements, the less likely we would become aware of it;
•	
It is the engagement partner’s assessment that the audit team collectively had the appropriate competence and capabilities to identify or 
recognise non-compliance with laws and regulations based on understanding of, and practical experience with audit engagements of a 
similar nature and complexity through appropriate training and participation; 
•	
We communicated relevant laws and regulations and potential fraud risks to all engagement team members and remained alert to any 
indications of fraud or non-compliance with laws and regulations throughout the audit. None of the matters relating to non-compliance 
with laws and regulations were determined as key audit matters; 
A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council’s website at: 
www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report.
Use of our report
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 and Company Statement of Cash Flows continued
For the year ended 31 December 2024
1. General information
Science Group plc (the ‘Company’) together with its subsidiaries (‘Science Group’ or the ‘Group’) is an international science & technology 
consultancy and systems organisation. The Group and Company Financial Statements of Science Group plc were prepared under the 
International Financial Reporting Standards (‘IFRS’) as adopted by the UK in conformity with the requirements of the Companies Act 2006 and 
have been audited by Grant Thornton UK LLP. Accounts are available from the Company’s registered office; Harston Mill, Harston, Cambridge, 
CB22 7GG.
The Company is incorporated and domiciled in England and Wales under the Companies Act 2006 and has its primary listing on the 
Alternative Investment Market of the London Stock Exchange (SAG.L). The value of Science Group plc shares, as quoted on the London Stock 
Exchange on 31 December 2024, was 453.0 pence per share (31 December 2023: 392.0 pence per share).
These Consolidated Financial Statements have been approved for issue by the Board of Directors on 21 March 2025.
Alternative performance measures (APM)
The Group uses alternative non-Generally Accepted Accounting Principles performance measures which are not defined within IFRS and 
may not be comparable across companies, as management believe these measures enable management and stakeholders to assess 
the underlying trading performance of the business as they exclude certain items that are considered to be significant in nature and/or 
quantum.
The APMs are consistent with how the businesses’ performance is planned and reported within the internal management reporting to the 
Board. The appropriateness of the APMs are kept under review by the Audit Committee. The key APMs that the Group uses and explanations 
on how they are calculated are set out below:
(a) Adjusted Operating Profit
The Group calculates this measure by adjusting to exclude certain items from operating profit namely: amortisation of acquisition related 
intangible assets, acquisition integration costs, share-based payment charges and other specified items that meet the criteria to be adjusted.
The criteria for the adjusted items in the calculation of adjusted operating profit is operating income or expenses that are material and 
either arise from an irregular and significant event or the income/cost is recognised in a pattern that is unrelated to the resulting operational 
performance. Materiality is defined as an amount which would reasonably be expected to influence the economic decisions of the users 
of these financial statements. Acquisition integration costs include all costs incurred directly related to the restructuring, relocation and 
integration of acquired businesses. Adjustments for share-based payment charges occur because: once the cost has been calculated, the 
Directors cannot influence the share-based payment charge incurred in subsequent years; it is understood that many investors/analysts 
exclude the cost from their valuation analysis of the business; and the value of the share option to the employee differs considerably in value 
and timing from the actual cash cost to the Group.
The calculation of this measure is shown on the Consolidated Income Statement.
(b) Adjusted Earnings Per Share
The Group calculates this measure by dividing adjusted profit after tax by the weighted average number of shares in issue and the 
calculation of this measure is disclosed in Note 12. The tax rate applied to calculate the tax charge in this measure is the tax at the blended 
corporation tax rate across the various jurisdictions for the year which is 23.3% (2023: 24.1%) which results in a comparable tax charge year 
on year.
(c) Net Funds
The Group calculates this measure as the net of cash and cash equivalents – Group cash and Borrowings. Client registration funds are 
excluded from this calculation because these monies are for the purpose of payment of registration fees to regulatory bodies. This cash is 
separately identified for reporting purposes and is unrestricted. This measure is calculated as follows:

The Directors believe that disclosing these alternative performance measures enhances shareholders’ ability to evaluate and analyse the 
underlying financial performance of the Group. Specifically, the adjusted operating profit measure is used internally in order to assess 
the underlying operational performance of the Group, aid financial, operational and commercial decisions and in determining employee 
compensation. The adjusted EPS measure allows the shareholder to understand the underlying value generated by the Group on a per 
share basis. Net funds represent the Group’s cash available for day-to-day operations and investments. As such, the Board considers these 
measures to enhance shareholders’ understanding of the Group results and should be considered alongside the IFRS measures.

2. Summary of significant accounting policies
The principal accounting policies applied in the preparation of these consolidated financial statements are set out below. These policies have 
been consistently applied to all of the years presented, unless otherwise stated.
2.1 Basis of preparation
The consolidated and Company financial statements of Science Group have been prepared under the historical cost convention, as modified 
by the revaluation of certain financial instruments at fair value. The financial statements are prepared under IFRS as adopted by the UK in 
conformity with the requirements of the Companies Act 2006.
Of the new standards and interpretations effective for the year ended 31 December 2024, there was no impact on the presentation of the 
financial statements of Science Group.
As set out in the Climate-Related Financial Disclosures the climate-related risks and opportunities and exposure faced by the Group at 
the lower end of scale. These risks and opportunities have been considered as part of the Directors’ assessment of going concern and 
impairment and are not considered to be material risks.
No income statement is presented for the Company as provided by Section 408 of the Companies Act 2006. The Company’s profit for the 
financial period after tax, determined in accordance with the Act, was £13,141,000 (2023: £6,096,000).
Going concern 
The Directors have undertaken a comprehensive going concern review. In adopting the going concern basis for preparing these 
Consolidated Financial Statements, the Directors have undertaken a review of the Group’s cash flows forecasts and available liquidity, 
along with consideration of the principal risks and uncertainties over an 18-month period to September 2026. Recognising the challenges 
of reliably estimating and forecasting the impact of external factors on the Group, the Directors have considered two forecasts in the 
assessment of going concern, along with a likelihood assessment of these forecasts being:
•	
Base case, which reflects the Directors’ current expectations of future trading; and
•	
Severe but plausible downside forecast which envisages a ‘stress’ or ‘downside’ situation.
For the severe but plausible downside forecast the assumptions include:
•	
A revenue reduction of 20% across all businesses (although due to diversification this is highly unlikely) 
•	
A more limited reduction in the costs
•	
A reduction of discretionary bonuses across the Group 
After reviewing the current liquidity position and the cash flow forecasts modelled under both the base case and stressed downside, the 
Directors consider that the Group has sufficient liquidity to continue in operational existence for a period of at least 18 months from the date 
of this report and are satisfied that it is appropriate to adopt the going concern basis of accounting in preparing the Consolidated Financial 
Statements.
In reaching these conclusions the Directors noted that the Group had a cash balance at 31 December 2024 of £38.6 million (excluding client 
registration funds) and net funds of £26.8 million, together with the undrawn Revolving Credit Facility (‘RCF’) of £25.0 million.
On 19 March 2025 the Group announced it had agreed new banking facilities with Lloyds Bank plc. The existing Term Loan and RCF 
were scheduled to expire in September 2026 and December 2026 respectively. There are two new Term Loans for a combined value of 
£12.0 million, each for 10 years expiring in March 2035. Each loan is secured solely and individually against the Group’s freehold properties: 
one loan to the property in Harston, near Cambridge, and, a second, independent loan to the property in Epsom, Surrey. The new, increased 
RCF is for £30.0 million, for a period of 5 years expiring in March 2030, an increase of £5.0 million over the 2021 RCF. The RCF also has a 
£10.0 million accordion, a further increase of £5.0 million over the 2021 RCF. The RCF is currently undrawn and therefore no covenants apply.
2.2 Changes in accounting policies
The accounting pronouncements which have become effective from 1 January 2024 and have therefore been adopted do not have a 
significant impact on the Group’s financial results or position.
2.3 Standards, IFRICs and other guidance applicable

2.5 Basis of consolidation
The basis of consolidation is set out below:
Subsidiaries – subsidiaries are entities controlled by Science Group. The Group controls an entity when it is exposed to, or has rights to, 
variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. The financial 
statements of subsidiaries are included in the consolidated financial statements from the date on which control commences until the date on 
which control ceases.
Investment in subsidiaries – in the Company accounts, investments in subsidiaries are stated at cost less any provision for impairment 
where appropriate.
Business combinations – the acquisition of subsidiaries is accounted for using the acquisition method. The cost of the acquisition is 
measured at the aggregate of the fair values, at the date of exchange, of assets given and liabilities incurred or assumed in exchange for 
control. The acquired Company’s identifiable assets, liabilities and contingent liabilities that meet the conditions for recognition under IFRS 3 
Business Combinations are recognised at their fair value at the acquisition date. Acquisition expenses are expensed as incurred.
Interests in equity-accounted investees – Associates are those entities in which the Group has significant influence, but not control or 
joint control, over the financial and operating policies. Interests in associates are accounted for using the equity method. They are initially 
recognised at cost, which includes transaction costs. Subsequent to initial recognition, the consolidated financial statements include the 
Group’s share of the profit or loss and other comprehensive income of equity-accounted investees, until the date on which significant 
influence ceases. The carrying value of the associate investment would not be impaired to the extent it is exceeded by the share of 
accumulated losses in associate. 
2.6 Segment reporting
Under IFRS 8, the accounting policy for identifying segments is based on the internal management reporting information that is regularly 
reviewed by the Chief Operating Decision Makers (‘CODMs’), being the Executive Board. The CODMs monitor the performance of these 
operating segments as well as deciding on the allocation of resources to them. 
The Group results are presented across 4 reporting Segments, determined by management based on the nature of the products and 
services provided: Consultancy Services, Systems – Submarine Atmosphere Management, Systems – Audio Chips and Modules, and Freehold 
Properties. Corporate costs, including the PLC costs and one-off costs relating to M&A activity, are not allocated to the Segments and are 
reported separately. This provides transparency and facilitates shareholder analysis of the component parts of the Group. 
The Consultancy Services Segment comprises the Research & Development, Regulatory & Compliance and Defence & Aerospace Practices. 
The Systems Businesses comprises Submarine Atmosphere Management (Critical Maritime Systems & Support (‘CMS2’)), which designs, 
develops and manufactures submarine atmosphere systems for the Defence sector; and, Audit Chips and Modules (Frontier Smart 
Technologies (‘Frontier’)), which is a provider of DAB/DAB+ radio semi-conductors/modules.
2.7 Intangible assets
All intangible assets, except goodwill, are stated at cost less accumulated amortisation and any accumulated impairment losses.
Goodwill – goodwill represents the amount by which the fair value of the cost of a business combination exceeds the fair value of net assets 
acquired. Goodwill is not amortised and is stated at cost less any accumulated impairment losses.
The recoverable amount of goodwill is tested for impairment annually or when events or changes in circumstance indicate that it might 
be impaired. Impairment charges are deducted from the carrying value and recognised immediately in profit or loss. For the purpose 
of impairment testing, goodwill is allocated to each of the Group’s cash generating units expected to benefit from the synergies of the 
combination. If the recoverable amount of the cash generating unit is less than the carrying amount of the unit, the impairment loss is 
allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit pro-rata on the 
basis of the carrying amount of each asset in the unit. An impairment loss recognised for goodwill is not reversed in a subsequent period.

2.7 Intangible assets
Acquisition related intangible assets – net assets acquired as part of a business combination includes an assessment of the fair value of 
separately identifiable acquisition related intangible assets, in addition to other assets, liabilities and contingent liabilities purchased. These 
are amortised over their useful lives which are individually assessed. The estimated useful economic life for acquired intangible assets, 
customer contracts and relationships are between 5 and 12 years. The assets are assessed on an annual basis for impairment and amortised 
over its remaining economic useful life. See Note 14 for further details.
2.8 Research and development expenditure
Expenditure on research activities is recognised in profit or loss as incurred.
Development expenditure is capitalised only if the expenditure can be measured reliably, the product or process is technically and 
commercially feasible, future economic benefits are probable, and the Group intends to and has sufficient resources to complete 
development and to use or sell the asset. Otherwise, it is recognised in profit or loss as incurred. Subsequent to initial recognition, 
development expenditure is measured at cost less accumulated amortisation and any accumulated impairment losses.
Any tax credit receivable under either the R&D Expenditure Credit scheme (‘RDEC’) or the Small or Medium-sized (‘SME’) scheme is treated 
as a taxable credit and included in the Group’s taxable income in accordance with IAS 12 Income Taxes. The credit is first used to offset the 
Group’s corporation tax liability for the same accounting period. After accounting for tax, the net benefit of the RDEC or SME schemes is 
recognised in the tax line.
2.9 Property, plant and equipment
Land and buildings as shown in the Notes to the Financial Statements comprise offices and laboratories at Harston Mill, Harston, Cambridge, 
UK and at Great Burgh, Epsom, UK. Land and buildings are shown at historical cost less accumulated depreciation. Historical cost includes 
expenditure that is directly attributable to the acquisition of the items.
Subsequent costs are included in the asset’s carrying amount or recognised as a separate asset, as appropriate, only when it is probable that 
the future economic benefit associated with the item will flow to Science Group and the cost of the item can be measured reliably. All other 
repairs and maintenance are charged to the income statement during the financial period in which they are incurred.
Land is not depreciated. Depreciation on all other property, plant and equipment is calculated using the straight-line method to allocate their 
cost less their residual values over their estimated useful lives, as follows:
Buildings		
	
25 years 
Furniture and fittings	
3-5 years 
Equipment	
	
3 years
The asset’s residual values and useful lives are reviewed, and adjusted if appropriate, at each balance sheet date. An asset’s carrying amount 
is written down immediately to its recoverable amount, when an indicator of impairment is identified. Gains and losses on disposals are 
determined by comparing proceeds with carrying amount. These are included in the income statement.
2.10 Cash and cash equivalents
Cash and cash equivalents comprise cash on hand and demand deposits, together with other short-term highly liquid investments (maturing 
not greater than 3 months) from the date of acquisition that are readily convertible into known amounts of cash which are subject to an 
insignificant risk of changes in value. Bank overdrafts are included in liabilities. 
2.11 Inventories
Inventories are stated at the lower of cost and net realisable value. Costs includes all cost incurred in bringing each product to its present 
location and condition, which comprises the cost of direct materials and third party charges. Net realisable value is the estimated selling 
price in the ordinary course of business less any applicable selling expenses.
2.12 Trade and other receivables
Trade and other receivables are carried at original invoice amount and are subsequently held at amortised cost less provision for 
impairment. The Group makes use of a simplified approach in accounting for trade and other receivables as well as contract assets and 
records the loss allowance as lifetime expected credit losses. These are the expected shortfalls in contractual cash flows, considering the 
potential for default at any point during the life of the financial instrument. The Group uses its historical experience, external indicators and 
forward-looking information to calculate the expected credit losses. The movement in the provision is recognised in the Consolidated Income 
Statement.
2.13 Trade and other payables
Trade and other payables are initially recognised at original invoice amount or transaction price and subsequently measured at amortised 
cost using the effective interest method.
2.14 Provisions
A provision is recognised if, as a result of a past event, the Group has a present legal or constructive obligation that can be estimated reliably, 
and it is probable that an outflow of economic benefits will be required to settle the obligation. 
Dilapidation provisions are recognised when the Group has an obligation to rectify, remove improvements, repair or reinstate the leased 
premises to a certain condition in accordance with the lease agreement. The provision is measured at the present value of the estimated cost 
of rectifying, repairing, or reinstating the leased premises at a specified future date. 
Provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects current market assessments of the 
time value of money and the risks specific to the liability. The unwinding of the discount is recognised as a finance cost.
2.15 Borrowings
Borrowings are recognised initially at fair value, net of transaction costs incurred. Borrowings are subsequently stated at amortised cost; any 
difference between the proceeds (net of transaction costs) and the redemption value is recognised in the income statement over the period 
of the borrowings using the effective interest method.
Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least 12 
months after the balance sheet date.
2.16 Financial instruments
(a) Classification
The Group classifies its financial assets in the following measurement categories:
(i)	
those to be measured subsequently at fair value (either through other comprehensive income, or through profit or loss), and
(ii)	
those to be measured at amortised cost.
The classification depends on the Group’s business model for managing the financial assets and the contractual terms of the cash flows.
For assets measured at fair value, gains and losses will either be recorded in profit or loss or other comprehensive income. For investments 
in debt instruments, this will depend on the business model in which the investment is held. For investments in equity instruments that are 
not held for trading, this will depend on whether the group has made an irrevocable election at the time of initial recognition to account for 
the equity investment at fair value through other comprehensive income.
(b) Measurement
At initial recognition, the Group measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit 
or loss, transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at 
fair value through profit or loss are expensed in profit or loss.
(c) Impairment 
The Group assesses, on a forward-looking basis, the expected credit losses associated with its debt instruments carried at amortised 
cost and FVOCI. The impairment methodology applied depends on whether there has been a significant increase in credit risk. For trade 
receivables, the Group applies the simplified approach permitted by IFRS 9, which requires expected lifetime losses to be recognised from 
initial recognition of the receivables. The Group recognises loss allowances for expected credit losses (‘ECLs’) on financial assets measured at 
amortised cost, debt investments measured at FVOCI and contract assets (as defined in IFRS 15).
The Group measures loss allowances at an amount equal to lifetime ECL, except for other debt securities and bank balances for which credit 
risk (i.e. the risk of default occurring over the expected life of the financial instrument) has not increased significantly since initial recognition, 
which are measured as 12-month ECL. Loss allowances for trade receivables and contract assets are always measured at an amount equal to 
lifetime ECL.
When determining whether the credit risk of a financial asset has increased significantly since initial recognition and when estimating ECL, 
the Group considers reasonable and supportable information that is relevant and available without undue cost or effort. This includes 
both quantitative and qualitative information and analysis, based on the Group’s historical experience and informed credit assessment and 
including forward-looking information.
Measurement of ECLs
ECLs are a probability-weighted estimate of credit losses. Credit losses are measured as the present value of all cash shortfalls (i.e. the 
difference between the cash flows due to the entity in accordance with the contract and the cash flows that the Group expects to receive). 
ECLs are discounted at the effective interest rate of the financial asset.
Credit-impaired financial assets
At each reporting date, the Group assesses whether financial assets carried at amortised cost and debt securities at FVOCI are credit 
impaired. A financial asset is ‘credit-impaired’ when one or more events that have a detrimental impact on the estimated future cash flows of 
the financial asset have occurred.
Write-offs
The gross carrying amount of a financial asset is written off (either partially or in full) to the extent that there is no realistic prospect of 
recovery.
(d) Derivative financial instruments and hedge accounting
Derivative financial instruments are accounted for at fair value through profit or loss except for derivatives designated as hedging 
instruments in cash flow hedge relationships, which require a specific accounting treatment. To qualify for hedge accounting, the hedging 
relationship must meet all of the following requirements:
•	
there is an economic relationship between the hedged item and the hedging instrument,
•	
the effect of credit risk does not dominate the value changes that result from that economic relationship,
•	
the hedge ratio of the hedging relationship is the same as that resulting from the quantity of the hedged item that the entity actually 
hedges and the quantity of the hedging instrument that the entity actually uses to hedge that quantity of hedged item, and
•	
At inception, there is formal designation and documentation of the hedging relationship.
The Group has entered into currency exchange instruments which have been designated as hedging instruments in cash flow hedge 
relationships. These arrangements have been entered into to mitigate foreign currency exchange risk arising from certain highly probable 
sales transactions denominated in foreign currency.

2.16 Financial instruments continued
(d) Derivative financial instruments and hedge accounting continued
In order to address interest rate risk, the Group has entered into phased interest rate swaps in order to fully hedge the loan borrowings. The 
interest rate swaps have been designated as hedging instruments in cash flow hedge relationships because the critical terms of the interest 
rate swaps entered exactly match the terms of the hedged item. 
All derivative financial instruments used for hedge accounting are recognised initially at fair value and reported subsequently at fair value in 
the Consolidated Balance Sheet.
To the extent that the hedge is effective, changes in the fair value of derivatives designated as hedging instruments in cash flow hedges 
are recognised in other comprehensive income and included within the cash flow hedge reserve in equity. Any ineffectiveness in the hedge 
relationship is recognised immediately in profit or loss.
At the time the hedged item affects profit or loss, any gain or loss previously recognised in other comprehensive income is reclassified from 
equity to profit or loss and presented as a reclassification adjustment within other comprehensive income. However, if a non-financial asset 
or liability is recognised as a result of the hedged transaction, the gains and losses previously recognised in other comprehensive income are 
included in the initial measurement of the hedged item. In the event that the currency exchange instrument is exercised in any month the 
gain is recognised as revenue.
If a forecast transaction is no longer expected to occur, any related gain or loss recognised in other comprehensive income is transferred 
immediately to profit or loss. If the hedging relationship ceases to meet the effectiveness conditions, hedge accounting is discontinued and 
the related gain or loss is held in the equity reserve until the forecast transaction occurs.
2.17 Equity
Equity comprises the following:
Share capital represents the nominal value of equity shares net of incremental costs directly attributable to the issue of new shares or 
options, net of tax.
Share premium represents the excess over nominal value of the fair value of consideration received for equity shares net of expenses of the 
share issue.
Treasury shares represent Company shares purchased directly by the Company to satisfy obligations under employee share incentive 
obligations.
Merger reserve is a reserve which reflects historical business combinations where merger relief was obtained. 
Translation reserve represents the foreign currency differences arising on translating foreign operations into the presentational currency of 
the Group.
Cash flow hedge reserve represents the outstanding notional amount of cash flow hedges, net of deferred tax, at the balance sheet date.
Retained earnings represent retained profits.
Where the Company purchases the Company’s equity share capital into treasury (treasury shares), the consideration paid, including any 
directly attributable incremental costs (net of income taxes) is deducted from equity attributable to the Company’s equity holders until the 
shares are cancelled, reissued, or disposed of. Where such shares are subsequently sold or reissued, including settlement of employee share 
incentive obligations, any consideration received, net of any directly attributable incremental transaction costs, and the related income tax 
effects are included in equity attributable to the Company’s equity holders. The credit for proceeds received is restricted to the purchase 
price of the treasury shares with the difference between prices paid for treasury shares and proceeds received taken to share premium. 
Where such shares are subsequently cancelled, the movement is recognised directly in equity with no gain or loss recognised in profit 
or loss.
2.18 Revenue recognition
The Group’s revenue arises from the following segments: 
Consultancy Services comprises the Research & Development, Regulatory & Compliance and Defence & Aerospace Practices. 
Systems – Submarine Atmosphere Management comprises the Critical Maritime Systems & Support (‘CMS2’) Business, which designs, 
develops and manufactures submarine atmosphere systems for the Defence sector; and 
Systems – Audio Chips and Modules comprises the Frontier Business, which is a provider of DAB/DAB+ radio semi-conductors/modules.
To determine whether to recognise revenue, the Group follows a 5-step process:
1	
Identifying the contract with a customer
2	
Identifying the performance obligations
3	
Determining the transaction price
4	
Allocating the transaction price to the performance obligations
5	
Recognising revenue when/as performance obligation(s) are satisfied.
(a) Consultancy Services
The Group has consultancy services contracts with clients. For each contract, performance obligations are identified, and the contract is 
assessed to be either a time and materials or a fixed price basis contract. 
Consultancy Services (Time and Materials contracts)
Revenue from providing consultancy services on a time and materials basis is recognised as the services are provided, on the basis of time 
worked at an hourly or daily rate and as expenses for materials are incurred.
Estimates of revenues or extent of progress toward completion are reviewed regularly and, where necessary, revised. Any resulting increases 
or decreases in estimated revenues are reflected in profit or loss in the period in which the circumstances that give rise to the revision 
become known by management.
The customer pays for the value of services provided based on an invoicing and payment schedule. If the services rendered by the Group at 
the reporting date exceed the payments received to date, an asset is recognised, within:
•	
trade receivables, if the sales invoice has been raised and an unconditional right to receive consideration exists;
•	
unbilled invoices on contracts, if the services rendered have not been invoiced but where an unconditional right to receive consideration 
exists;
•	
amounts recoverable on contract if the services rendered have not been invoiced and no unconditional right to receive consideration 
exists.
Consultancy Services (Fixed Price contracts)
The Group provides fixed price regulatory and compliance services to US customers, to support in the renewal of licenses and product 
registrations with US state regulatory authorities. Customers simultaneously receive and consume the benefits provided by each individual 
renewal. Revenue from these contracts is recognised using an output method based on the number of renewals completed and submitted 
during the reporting period based on the average revenue per renewal.
The Group receives cash from clients which are pass through funds solely for the purpose of payment of registration fees to regulatory 
bodies and for which no revenue is recognised.
Where the contract is advisory, technical or project management, the customer receives and consumes the benefits of the service as the 
Group performs. Revenue is recognised overtime, using an input basis, based on costs incurred compared to total contract costs. Costs are 
only included in the measurement of progress towards satisfying the performance obligation where there is a direct relationship between 
the input and the satisfaction of the performance obligation.
For contracts where the Group becomes entitled to invoice customers based on achieving a series of performance related milestones, at the 
point a customer is invoiced, any amount previously recognised as amounts due from contract customers is reclassified to trade receivables. 
If the milestone payment exceeds the revenue recognised to date under the cost-to-cost method, then the Group recognises a contract 
liability for the difference. There is not considered to be any significant financing components as the period between recognition of revenue 
and milestone payment is always less than one year.
(b) Design and Manufacture of Submarine Atmosphere Systems
The Group’s operations generate revenues through both the design and manufacture of submarine atmosphere systems.
The Group determines the transaction price based on the consideration to which the Group expects to be entitled in a contract with a 
customer. Where the amount of consideration is variable (e.g. due to trade discounts, late delivery penalties and other similar items) the 
Group includes the variable consideration in the transaction price only to the extent that it is highly probable that a significant reversal in the 
amount of cumulative revenue recognised will not occur.
The Group recognises revenue when it transfers control of a product or service to a customer as more fully explained below.
The Group designs and manufactures mission-critical systems under long-term contracts with customers. The promises in these contracts 
include the design and manufacture of systems for delivery to the customer and standard assurance warranties. The promises in these 
contracts are combined as a single performance obligation because the customer cannot benefit from the promises on their own, and 
they are not separately identifiable in the context of the contract. In some instances, the contract will also include a promise to install the 
equipment at the customer site. Where installation is included in the contract, this is not generally considered a separate performance 
obligation as the promise is not separately identifiable in the context of the contract.
On inception of each contract, the Group assesses whether ongoing contractual obligations represent a distinct performance obligation. 
If the performance obligation is considered distinct e.g. relates to the delivery of more than one main system to separate boats, each main 
system for each separate boat is treated as a separate performance obligation and revenue recognised under a separate Project Code. 
Where it is multiple systems for a single boat, this is considered to be a single performance obligation and revenue is recognised under a 
single Project Code.
The systems that are designed and manufactured are bespoke for each customer and do not have an alternative use to the Group.
Over time revenue recognition
For fixed price contracts within this category, where the Group has an enforceable right to payment for performance completed to date, 
being recovery of costs incurred in satisfying the performance obligation plus a reasonable profit margin, the performance obligation is 
satisfied over time. The measurement of progress towards complete satisfaction of the performance obligation is measured using the input 
method, based on costs incurred compared to total contract costs.

2.18 Revenue recognition continued
(b) Design and Manufacture of Submarine Atmosphere Systems continued
For contracts billed on a time-and-materials basis, the measurement of progress towards complete satisfaction of the performance 
obligation is measured using the output method (consistent with the time and materials incurred). Under IFRS15.B16, the Group recognises 
revenue in line with amounts it has the right to invoice.  See Note 28 for critical accounting estimates and judgements in relation to certain 
contracts within this category.
Costs are only included in the measurement of progress towards satisfying the performance obligation where there is a direct relationship 
between the input and the satisfaction of the performance obligation. Full costs to complete, including Labour and material costs are 
considered the most faithful depiction of progress as this most accurately reflects the value provided to the customer. The Group designs 
and manufactures bespoke systems with the time allocated to projects of engineers and technicians, as well as bespoke materials procured 
from suppliers which can take a number of months to be manufactured and delivered to the Group.
The Group does not incur costs in respect of the components whilst they are being manufactured by the supplier. It is only once the goods 
are delivered and accepted by the Group that costs associated with the materials are incurred and revenue is recognised. Where payments 
on account are made to the supplier which are in nature milestone payments, these are not considered to be reflective of costs incurred to 
date by the supplier in the manufacturing of the components. Material costs are recognised at an amount equal to the cost of the good used 
to satisfy the performance obligation.
For contracts where the Group becomes entitled to invoice customers based on achieving a series of performance related milestones, at the 
point a customer is invoiced, any amount previously recognised as amounts due from contract customers is reclassified to trade receivables. 
If the milestone payment exceeds the revenue recognised to date under the cost-to-cost method, then the Group recognises a contract 
liability for the difference. 
There is not considered to be any significant financing components as the period between recognition of revenue and milestone payment is 
always less than one year.
Point in time revenue recognition
For contracts where the Group does not have an enforceable right to payment for performance completed to date, being recovery of 
costs incurred in satisfying the performance obligation plus a reasonable profit margin, revenue is recognised at a point in time. For these 
contracts, revenue is recognised at the point of customer delivery (as defined in each specific contract) of the system, as this is the point at 
which the customer is in control of the deliverable, has the risks and rewards of ownership and the Group has a present right for payment for 
the deliverable. 
Some contracts will include:
•	
a promise to store the equipment or an option to purchase storage services at a future date. Storage services are provided in the period 
between acceptance of the equipment by the customer and shipping. Where storage services are provided, this is considered a separate 
performance obligation, and/or
•	
extended service warranties which are a separate performance obligation. 
For storage services, the customer receives and consumes the benefit over the storage period. The performance obligation is satisfied over 
time. Revenue is recognised on an output basis, based on daily rate for the period of storage.
For extended warranties, the customer receives and consumes the benefit of the warranty over the extended warranty period. The 
performance obligation is satisfied over time, based on straight line recognition over the period of the warranty, which is used to measure 
progress towards complete satisfaction of the extended warranty performance obligation. 
For the supply of consumables, the customer receives the benefit of the service on delivery (as defined in the contract) of the consumable. 
This is the point at which the customer is in control of the deliverable, has the risks and rewards of ownership and the Group has a present 
right for payment for the deliverable. Where the Group resells consumables products to customers an assessment is made as to whether the 
Group is acting as a principal or agent. 
There have been no situations identified, based on these assessments, where the directors have concluded the Group is acting as an agent 
rather than a principal based on the following indicators:
•	
the Group has control of the goods prior to them being transferred to the customer,
•	
the Group is deemed to have control where the Group holds the responsibility of designing and manufacturing the items and is 
therefore primarily responsible for fulfilling the promise to provide the goods,
•	
the Group holds the inventory risk before goods are transferred to the customer,
•	
the Group has discretion in establishing the price for the goods.
Payment terms under these contracts are typically 30 days.
Parts management – The Group has a parts management contract, whereby the Group manages the parts supply chain for a customer. This 
contract contains two performance obligations being asset availability, and supply of consumables.
In terms of asset availability, the Group’s performance does not create an asset with an alternative use to the Group and the Group has an 
enforceable right to payment for performance completed to date, being recovery of costs incurred in satisfying the performance obligation 
plus a reasonable profit margin. The customer also simultaneously receives and consumes the benefits of the asset availability service as 
the Group performs. Revenue is recognised as a provision of assets are provided and control passes to the customer on the sale of the 
goods. Where it is concluded that the customer has material rights under the contract for asset availability service then this will be assessed 
in measuring progress towards complete satisfaction of the performance obligation that depicts the Group’s performance in providing the 
asset availability service to the customer. 
The contract price for asset availability includes variable consideration in the form of rebates based on achievement of KPI’s within the 
contract. The expected value approach, which is based on the sum of probability weighted amounts for a range of possible outcomes, has 
been used to estimate the transaction price. The variable consideration is trued up at the end of each reporting period to reflect changes in 
the period and conditions that exist at the period end.
For the supply of consumables, revenue is recognised at a point in time because the customer receives the benefit of the service on delivery 
(as defined in the contract) of the consumable. This is the point at which the customer is in control of the deliverable, has the risks and 
rewards of ownership and the Company has a present right for payment for the deliverable. 
Payment terms under these contracts are typically 30 days. 
Maintenance of equipment – The Group has contracts for the maintenance and servicing of customer vessels with a 12-month assurance 
warranty. These contracts contain a single promise and performance obligation. These assurance-type warranties are not considered to be 
performance obligations, so revenue is not allocated to them. The estimated costs of serving these warranties are recognised as provisions 
under IAS 37 ’Provisions, Contingent Liabilities and Contingent Assets’.
The performance of the Group enhances the vessels, which are controlled by the customer, as the Group performs. Customers 
simultaneously receive and consume the benefits of the enhancements. Revenue is recognised over time. The Group uses an input method, 
based on labour hours, costs incurred and materials, to measure complete satisfaction of the performance obligation. Costs are only 
included in the measurement of progress towards satisfying the performance obligation where there is a direct relationship between the 
input and the satisfaction of the performance obligation. 
Payment terms under these contracts are typically 30 days.
(c) Subscription Income
The Group has membership subscription contracts with customers. Subscription income for membership services provided over an annual 
contractual period is recognised in the income statement on a straight-line basis over the period of the contract.
(d) Product and Associated Revenue
The Group supplies audio chips and modules to customers based on purchase orders received from customers. Revenue is recognised upon 
the transfer of control of promised products or services and for the majority of revenue, transfer of control occurs once the product has been 
collected, as the terms are ex-works. For smart radio products, ongoing IT infrastructure services are provided over a period of time in order 
for the consumer to use the full functionality of the end product. When such services have been identified as both capable of being distinct 
and separately identifiable from the related tangible product, the associated revenue allocated to such services is recognized over time. 
Where there are separate performance obligations in a contract (being the product and the ongoing IT infrastructure services), it has been 
determined that directly observable prices do not exist for these performance obligations, therefore the transaction price is calculated as the 
expected cost plus a margin. 
Revenue is recorded net of sales tax and relevant sales incentives when the performance conditions are met. Sales incentives are rebates 
offered to customers and paid based on total sales made to respective customers each year. The rebates are estimated on a regular basis by 
using the most likely amount method. The rebates will be accrued only to the extent that it is highly probable that a significant reversal in the 
amount of cumulative revenue recognised will not occur. To the extent unpaid, the rebate liability is presented under accruals.
The Group recognises contract liabilities for consideration received in respect of unsatisfied performance obligations and reports these 
amounts as trade and other payables in the statement of financial position. Similarly, if the Group satisfies a performance obligation before it 
receives the consideration, the Group recognises as trade and other receivables in its statement of financial position.
2.19 Foreign currency
(a) Functional and presentation currency – items included in the financial statements of each of Science Group’s entities are measured 
using the currency of the primary economic environment in which the entity operates (‘the functional currency’). The Consolidated Financial 
Statements are presented in Sterling, which is the Group’s functional and presentation currency.
(b) Transactions and balances – foreign currency transactions are translated into the functional currency using the exchange rates prevailing 
at the dates of the transactions. Foreign exchange gains and losses resulting from the settlement of such transactions and from the 
translation at year end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in the income 
statement.
In respect of translation differences on non-monetary items, items held at cost are translated at the exchange rate at the date of transaction.

2.19 Foreign currency continued
(c) Group companies – the results and financial position of all Science Group entities (none of which has the currency of a hyperinflationary 
economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows:
(i)	
assets and liabilities for each balance sheet presented are translated at the closing rate at the date of that balance sheet.
(ii)	
income and expenses for each income statement are translated at average exchange rates (unless this average is not a reasonable 
approximation of the cumulative effect of the rates prevailing on the transaction dates, in which case income and expenses are 
translated at the dates of the transactions).
(iii)	 all resulting exchange differences are recognised as a separate component of equity.
(iv)	 on disposal of a foreign subsidiary the accumulated translation differences recognised in equity are reclassified to profit or loss and 
recognised as part of the gain or loss on disposal.
2.20 Employee benefits
(a) Post employment benefit plans
The Group provides post-employment benefits through various defined contribution plans.
Defined contribution plans
The Group pays fixed contributions into independent entities in relation to several retirement plans and insurances for individual employees. 
The Group has no legal or constructive obligations to pay contributions in addition to its fixed contributions, which are recognised as an 
expense in the period that related employee services are received.
(b) Share-based compensation
Science Group operates an equity-settled, share-based compensation plan, awarding options to certain employees. More details on the 
scheme are reported in Note 22. The fair value of the employee services received in exchange for the grant of the options is recognised as 
an expense. The total amount to be expensed over the vesting period is determined by reference to the fair value of the options granted, as 
calculated by using an appropriate valuation method. 
The Black-Scholes model excludes the impact of any non-market vesting conditions (for example profitability and sales growth targets). 
The Monte Carlo and Binomial Option Pricing models incorporate any market performance conditions. Non-market vesting conditions are 
included in assumptions about the number of options that are expected to become exercisable. 
The Group has the following plans.
•	
The Performance Share Plan (‘PSP’): Targets are set on EPS over three years, with options valued using the Binomial Option Pricing model.
•	
The Enhanced Executive Incentive Addendum: Options for directors and senior managers with vesting conditions based on the share 
price, valued using the Monte Carlo model.
At each balance sheet date, the Group revises its estimates of the number of options that are expected to become exercisable. It recognises 
the impact of the revision of original estimates, if any, in the income statement, and a corresponding adjustment to equity over the remaining 
vesting period. The proceeds received net of any directly attributable transaction costs are credited to share capital (nominal value) and 
share premium when the options are exercised.
The employer’s NIC liability on vested share options, or the proportion that have vested, is recognised as a provision. As the employee is 
contractually responsible for the Employer’s NIC on any share options exercised (and is required to remit this sum to the Group prior to the 
share options being exercised) a corresponding current asset is recognised.
The share-based compensation charge in the Group accounts is based only on those option holders employed directly by the Group.
(c) Termination benefits
Termination benefits are payable when employment is terminated before the normal retirement date, or whenever an employee accepts 
voluntary redundancy in exchange for these benefits. Science Group recognises termination benefits at the earlier of when the Group can no 
longer withdraw the offer of the termination benefit and when the Group recognises any related restructuring costs.
(d) Profit-sharing and bonus plans
Science Group recognises a liability and an expense for bonuses and/or profit-sharing, based on the incentive plans approved by the 
Remuneration Committee. Science Group recognises a liability where contractually obliged or where there is a past practice that has created 
a constructive obligation.
(e) Sales commission
Science Group operates a sales commission scheme for relevant sales staff. A liability and expense is recognised based on sales made 
by employees who are eligible for the scheme, and is calculated using the commission scheme rules. Sales commission is typically paid 
quarterly. As the amortisation period of such costs, if capitalised, would be less than one year, the Group makes use of the practical 
expedient in IFRS 15 and expenses them as incurred.
2.21 Taxation
The tax expense for the period comprises current and deferred tax. Tax is recognised in the income statement, except to the extent 
that it relates to items recognised in other comprehensive income, or directly in equity. In this case, the tax is also recognised in other 
comprehensive income or directly in equity, respectively.
Income tax is provided at amounts expected to be paid (or recovered) using the tax rates and laws of the relevant countries that have been 
enacted or substantively enacted by the balance sheet date.
Deferred income tax is provided, using the liability method, on temporary differences arising between the tax bases of assets and liabilities 
and their carrying amounts in the consolidated financial statements. However, if the deferred income tax arises from goodwill, the initial 
recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither 
accounting nor taxable profit nor loss, it is not accounted for. Deferred income tax is determined using tax rates (and laws) that have been 
enacted or substantively enacted by the balance sheet date and are expected to apply when the related deferred income tax asset is 
realised, or the deferred income tax liability is settled.
Deferred income tax assets are recognised to the extent that it is probable that future taxable profit will be available against which the 
temporary differences can be utilised.
Deferred income tax is provided on temporary differences arising on investments in subsidiaries, except where the timing of the reversal of 
the temporary difference is controlled by Science Group, and it is probable that the temporary difference will not reverse in the foreseeable 
future.
The Group performed a reasonable estimate of all amounts involved to determine the R&D tax credits to be recognised in the period to 
which it relates.
2.22 Leases
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 the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract 
conveys the right to control the use of an identified asset, the Group uses the definition of a lease in IFRS 16.
(a) As a lessee
The Group has leases, principally for office space, in the UK, Europe, North America and China. Office rental contracts are typically 
negotiated for terms ranging from 2 and 10 years with some including extension options. The Group does not enter into sale and leaseback 
arrangements. None of the leases included residual value guarantees or purchase options. All the leases are negotiated on an individual 
basis and contain different terms and conditions such as break clauses, rent reviews and extensions. At commencement or on modification 
of a contract that contains a lease component, the Group allocates the consideration in the contract to each lease component on the basis of 
its relative stand-alone prices. However, for the leases of property the Group has elected not to separate non-lease components and account 
for the lease and non-lease components as a single lease component.
The Group recognises a right-of-use asset and a lease liability at the lease commencement date. The right-of-use asset is initially measured 
at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, 
plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset 
or the site on which it is located, less any lease incentives received.
The right-of-use asset is subsequently depreciated using the straight-line method from the commencement date to the end of the lease 
term, unless the lease transfers ownership of the underlying asset to the Group by the end of the lease term or the cost of the right-of-
use asset reflects that the Group will exercise a purchase option. In that case the right-of-use asset will be depreciated over the useful life 
of the underlying asset, which is determined on the same basis as those of property and equipment. In addition, the right-of-use asset is 
periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.
The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted 
using the interest rate implicit in the lease or, if that rate cannot be readily determined, being the rate of interest which a lessee would have 
to pay to borrow the funds necessary to obtain an asset, obtained from various external financing sources and makes certain adjustments to 
reflect the terms of the lease and type of the asset leased.
The Group determines its incremental borrowing rate as a lessee by obtaining interest rates from various external financing sources and 
makes certain adjustments to reflect the terms of the lease and type of the asset leased.
As of the balance sheet date, there are no leases that have been committed to but have not yet commenced.
Lease payments included in the measurement of the lease liability comprise the following:
•	
fixed payments, including in-substance fixed payments.
•	
variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date.
•	
amounts expected to be payable under a residual value guarantee.
•	
the exercise price under a purchase option that the Group is reasonably certain to exercise, lease payments in an optional renewal 
period if the Group is reasonably certain to exercise an extension option, and penalties for early termination of a lease unless the Group 
is reasonably certain not to terminate early.
The lease liability is measured at amortised cost using the effective interest method. It is remeasured when there is a change in future lease 
payments arising from a change in an index or rate, if there is a change in the Group’s estimate of the amount expected to be payable under 
a residual value guarantee, if the Group changes its assessment of whether it will exercise a purchase, extension or termination option or if 
there is a revised in-substance fixed lease payment. In general the Group assumes that leases will run to the end of the break period.

2.22 Leases continued
(a) As a lessee continued
When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the right-of-use asset or is 
recorded in profit or loss if the carrying amount of the right-of-use asset has been reduced to zero.
The Group presents right-of-use assets that do not meet the definition of investment property in ‘property, plant and equipment’ and 
associated lease obligations in ‘lease liabilities’ in the Consolidated Balance Sheet.
Short-term leases and leases of low-value assets
The Group has elected not to recognise right-of-use assets and lease liabilities for leases of low-value assets and short-term leases, including 
IT equipment. The Group recognises the lease payments associated with these leases as an expense on a straight-line basis over the lease 
term. The total expense for short-term leases and leases with low-value assets for the year ended 31 December 2024 was £0.1 million (2023: 
£0.1 million). 
(b) As a lessor
At inception or on modification of a contract that contains a lease component, the Group allocates the consideration in the contract to each 
lease component on the basis of their relative standalone prices.
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, the Group makes an overall assessment of whether the lease transfers substantially all of the risks and rewards incidental to ownership 
of the underlying asset. If this is the case, then the lease is a finance lease; if not, then it is an operating lease. As part of this assessment, the 
Group considers certain indicators such as whether the lease is for a major part of the economic life of the asset.
The Group recognises lease payments received under operating leases as income on a straight-line basis over the lease term.
2.23 Dividends paid
Dividends are recognised as a liability in the period in which the shareholders’ right to receive payment has been established.
2.24 Dividend income
Dividend income is recognised when the right to receive payment is established.
3. Financial risk management
3.1 Financial risk factors
Science Group’s activities expose it to a variety of financial risks: market risk (including currency risk and fair value interest risk), credit risk, 
liquidity risk and cash flow interest rate risk. Science Group’s overall financial risk management programme focuses on the unpredictability of 
financial markets and seeks to minimise potential adverse effects on Science Group’s financial performance. Science Group uses derivative 
financial instruments to hedge certain risk exposures.
(a) Foreign currency sensitivity
Science Group operates internationally and is exposed to foreign exchange risk arising from various currency exposures, primarily with 
respect to the US Dollar and Euro. Foreign exchange risk arises from commercial transactions, recognised assets and liabilities.
To manage the Group’s foreign exchange risk arising from commercial transactions, recognised assets and liabilities, entities in Science 
Group may use forward contracts and other instruments. The Group acquired a currency exchange instrument to cap the US Dollar/GBP 
rate in relation to the Consultancy Services segment US Dollar revenue through to the end of 2024. The instrument is a US Dollar/GBP cap 
set at $1.25/£1 which applies to $1.0 million per month. In the event that the exchange rate moves above $1.25/£1 at set monthly dates 
the Consultancy Services segment was guaranteed to receive £0.8 million for $1.0 million. Similar instruments have also been acquired in 
relation to 2025 covering $1.0 million per month at a blended rate of $1.275/£1 (see Note 24). Foreign exchange risk arises when commercial 
transactions and recognised assets and liabilities are denominated in a currency that is not the entity’s functional currency. The Group 
finance function is responsible for managing the net position in each foreign currency primarily by selling monies held in currency into GBP 
on a regular basis. 
Science Group has certain investments in foreign operations, whose net assets are exposed to foreign currency translation risk. Foreign 
currency denominated financial assets and liabilities, translated into GBP at the closing rate, are as follows:

financial assets and financial liabilities and the US Dollar/GBP exchange rate and Euro/GBP exchange rate. It assumes a 10.0% change of 
the US Dollar/GBP exchange rate as at 31 December 2024 (2023: +/-10.0%). A 10.0% change is considered for the Euro/GBP exchange rate 
(2023: +/-10.0%). If the GBP had strengthened against the US Dollar and Euro by 10.0% (2023: 10.0%) respectively then this would have had 
the following impact:

For a 10.0% weakening of GBP against the relevant currency, there would be a comparable but opposite impact on the Consolidated Income 
Statement and equity.
The Company did not hold any material financial assets or liabilities in foreign currencies at the start nor end of the year.
The currency rate movements against the US Dollar and Euro at year end compared to the previous year end were 1.7% (2023: -5.2%) 
and -4.9% (2023: -2.3%) respectively. Exposures to foreign exchange rates vary during the year depending on the volume and value of 
transactions.
(b) Interest rate risk
Science Group manages its longer-term cash flow interest rate risk by using floating-to-fixed interest rate swaps. Such interest rate swaps 
have the economic effect of converting borrowings from floating rates to fixed rates. Generally, Science Group raises long-term borrowings 
at floating rates and swaps them into fixed rates that are lower than those available if Science Group borrowed at fixed rates directly. Under 
the interest rate swaps, Science Group agrees with other parties to exchange, at specified intervals (typically quarterly), the difference 
between fixed contract rates and floating rate interest amounts calculated by reference to the agreed notional principal amounts.
Science Group’s bank borrowings and its interest rate profile are as follows:
Group

13,000

SONIA+2.6%
SONIA+2.6%
For benchmark rates of interest, Science Group refers to SONIA. The bank loan is secured via a fixed charge over certain assets of Science 
Group and is repayable as disclosed in Note 23. Terms and conditions of the interest rate swaps are as disclosed in Note 23. The interest 
rate swaps mature in accordance with the repayment profile of the loan: £0.8 million in September 2025 and the balance of £11.0 million in 
September 2026. Given the interest rate swaps in place there is no exposures to interest rate movements to P&L and an immaterial impact 
to equity. If the SONIA rate goes up by 25 basis points, it is estimated that the net impact to equity would be approximately £37,000 (2023: 
£64,000).
(c) Credit risk analysis
Science Group has policies in place to ensure that sales are made to clients with an appropriate credit history. Derivative counterparties 
and cash transactions are limited to high-credit-quality financial institutions although counterparty risk is not negligible. Science Group has 
policies that limit the amount of credit exposure to any financial institution. Science Group’s exposure to credit risk is limited to the carrying 
amount of financial assets recognised at the balance sheet date, as summarised below:

3.1 Financial risk factors continued
(c) Credit risk analysis continued
Science Group monitors defaults of customers and other counterparties identified either individually or by group and incorporates this 
information into its credit risk controls. Where available at reasonable cost, external credit ratings and/or reports on customers and other 
counterparties are obtained and used. Science Group’s policy is to deal only with creditworthy counterparties or to require settlement in 
advance, although there can be no certainty that counterparty creditworthiness will be maintained. Cash balances are held with more than 
one creditworthy institution.
Management reviews the credit status of the financial institutions with whom it holds its deposits. Science Group’s management considers 
that all in relation to the above financial assets the expected credit losses are considered to be insignificant. An analysis of trade and other 
receivables that are considered to be impaired are disclosed in Note 18. None of Science Group’s financial assets are secured by collateral 
nor other credit enhancements.
(d) Liquidity risk analysis
Science Group manages its liquidity needs by monitoring scheduled debt servicing payments for long-term financial liabilities as well as cash 
outflows due in day-to-day business. Liquidity needs are monitored on a weekly and monthly basis. Long-term liquidity needs for a quarterly 
and semi-annual period are reviewed monthly.
Science Group maintains cash to meet its liquidity requirements in interest bearing current accounts.

3.2 Fair value estimation
Financial assets and liabilities measured at fair value in the balance sheet are grouped into three levels based on the significance used in 
measuring the fair value of the financial assets and liabilities. The fair value hierarchy has the following levels:
•	
level 1 – quoted prices (unadjusted) in active markets for identical assets or liabilities
•	
level 2 – inputs other than quoted market prices included within level 1 that are observable for an asset or liability, either directly (i.e. as 
prices) or indirectly (i.e. derived from prices)
•	
level 3 – input for the asset or liability that are not based on observable market data (unobservable inputs)
The level within which the financial asset or liability is determined is based on the lowest level of significant input to the fair value 
measurement.
The Group has measured the interest rate swaps and the currency exchange instruments in non-current financial instruments and 
current financial instruments in the Consolidated Balance Sheet respectively at fair value under level 2. The Group’s finance team performs 
valuations of financial items for financial reporting purposes, including level 2 fair values, in consultation with third party valuation specialists 
for complex valuations. Valuation techniques are selected based on the characteristics of each instrument, with the overall objective of 
maximising the use of market-based information. These contracts have been fair valued using observable interest rates and exchange rates 
corresponding to maturity of the contract. The effects of non-observable inputs are not significant for both instruments. 
The Group has the following financial assets and liabilities. IFRS 13 requires disclosure of the fair value measurements for each instrument 
using the fair value hierarchy levels as below:

3.3 Capital management
The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern in order to provide returns 
for shareholders and benefits for other stakeholders and to maintain an optimal structure to reduce the cost of capital and to provide funds 
for merger and acquisition activity. The Group primarily views its capital as being its shareholders’ funds, net funds (being Group cash less 
borrowings) and the freehold properties at Harston Mill and Great Burgh.

4. Segment information
The Consultancy Services Segment comprises the Research & Development, Regulatory & Compliance, and Defence & Aerospace Practices. 
The Systems – Submarine Atmosphere Management Segment comprises the Critical Maritime Systems & Support (‘CMS2’) Business, which 
designs, develops and manufactures submarine atmosphere systems for the Defence sector. The Systems – Audio Chips and Modules 
Segment comprises the Frontier Business, which is a provider of DAB/DAB+ radio semi-conductors/modules.
The Group’s segmental reporting shows the performance of the operating businesses separately from the value generated by the Group’s 
significant freehold property assets and the corporate costs. The Consultancy Services Segment consists of three Practices: (i) Research & 
Development, (ii) Regulatory & Compliance and (iii) Defence & Aerospace. Financial information is provided to the Chief Operating Decision 
Makers (‘CODMs’) in line with this structure: the Consultancy Services Segment; the two Systems Businesses (Submarine Atmosphere 
Management and Audio Chips and Modules); the Freehold Properties and Corporate costs.  
The Consultancy Services Practices are aggregated into one Consultancy Services Segment because the Practices provide similar consultancy 
services and share economic characteristics, including the timing of revenue recognition, the nature of performance obligations, and the 
nature of costs incurred in the provision of said performance obligations. The CODM reviews this Segment as a whole. This aggregation does 
not impact the user’s ability to understand the entity’s performance, its prospects for future cash flows or the user’s decisions about the 
entity as a whole as it is a fair representation of the performance of each service line.
Consultancy Services revenue includes all consultancy fees and other revenue includes recharged materials and expenses relating directly 
to Consultancy Services activities. Systems - Submarine Atmosphere Management revenue includes the development, manufacture and 
support of specialist systems for submarine atmosphere management, used in the UK and international naval defence markets. Systems - 
Audio Chips and Modules revenue includes sales of chips and modules which are incorporated into digital radios. The Freehold Properties 
Segment includes the results for the two freehold properties owned by the Group. Income is derived from third party tenants from the 
Harston Mill site and from internal businesses which have been charged fees at an arm’s length market rental rate for their utilised property 
space and associated costs. Corporate costs include PLC/Group costs.
The segmental analysis is reviewed to operating profit. Other resources are shared across the Group.

*	 An amount of £2,408,000, previously disclosed under ‘Amount recoverable on contracts’ within ‘Trade and other receivables’ is now presented under ‘Unbilled invoices on contracts’ (Note 
18) reflecting a correction in the presentation to align with the nature of the balances, which are uninvoiced but where an unconditional right to receive consideration exists. The 2023 
‘Amount recoverable on contracts’ included in ‘Trade and other receivables’ has been restated from £6,708,000 to £4,300,000.
*    An amount of £1,881,000, previously disclosed under ‘Contract liabilities’ within ‘Trade and other payables’ is now presented under ‘Client registration funds on account’ (Note 20). The 
2023 ‘Contract liabilities’ included in ‘Trade and other payables’ has een restated from £17,550,000 to £15,669,000.
The amounts recoverable on contracts primarily relate to the Group’s rights to consideration for work performed but not billed at the 
reporting date. The amounts recoverable on contracts are transferred to receivables when the rights to receive cash become unconditional, 
i.e. when the Group has fulfilled all the performance obligations and an invoice is issued to the customer.
The contract liabilities primarily relate to the advance consideration received from customers (Note 20). The remainder represents revenue 
to be recognised over time as the work is performed. The balance of £2.9 million (2023: £1.9 million) that relates to pass through fees which 
represent advance payments for registration fees to be paid to regulatory bodies is excluded as these balances are not recognised as 
revenue (Note 20).

(2,095)
The adjustments in prior years are due to estimation differences related to the tax charge. In 2024, the Group opted to use tax losses sooner 
than anticipated, resulting in a higher than normal current tax adjustment offset by a matching deferred tax adjustment.
The corporation tax on Science Group’s profit before tax differs from the theoretical amount that would arise using the blended corporation 
tax rate across the various jurisdictions applicable to profits/(losses) of the consolidated companies of 23.3% (2023: 24.1%) as follows:

£0.7 million (2023: £0.5 million). The Group performed a reasonable estimate of all amounts involved to determine the R&D tax credits to  
be recognised in the period to which it relates.

At 31 December 2024, Science Group had £21.4 million (2023: £29.3 million) of tax losses, the largest component of which related to Frontier 
(£16.8 million (2023: £19.2 million)). Of the Frontier losses balance, £7.0 million (2023: £9.1 million) is recognised as a deferred tax asset 
which is anticipated to be used to offset future taxable profits. The balance of £9.8 million (2023: £10.1 million) has not been recognised as 
a deferred tax asset due to the uncertainty in the timing of utilisation of these losses. Aside from these amounts, the Group has other tax 
losses of £4.6 million (2023: £4.2 million) unrecognised as a deferred tax asset due to the low probability that these losses will be utilised. 
Factors affecting future tax charges 
Deferred tax assets and liabilities were calculated at the substantively enacted corporation tax rates in the respective jurisdictions, taking into 
account the impact of any known future changes.

Impairment review of goodwill
The Group tests goodwill annually for impairment or more frequently if there are indications that goodwill might be impaired. The 
recoverable amounts of the Cash Generating Units (‘CGUs’) are determined from value in use. (CGUs are a description of the smallest 
identifiable group of assets that generate cash inflows (such as a whether it is a product line, a business operation or a reportable segment 
as defined in IFRS8)). The key assumptions for the value in use calculations are those regarding the discount rates, profit margins, and rates 
of growth or decline in revenue.
The Group prepares the cash flow forecasts derived from the most recent annual financial plan approved by the Board and extrapolates 
cash flows for the following four years based on forecast rates of growth or decline in revenue by the CGU. Beyond 5 years cash flows were 
extrapolated using a terminal growth rate of 2.5% based on historic average inflation rates.
The Group monitors its post-tax weighted average cost of capital and those of its competitors using market data. In considering the discount 
rates applying to CGUs, the Directors have considered the relative sizes, risks and the inter-dependencies of its CGUs. The impairment 
reviews use a discount rate adjusted for pre-tax cash flows and are included in the table above.
The revenue growth rates vary by CGU and are included in the relevant CGU section below:
R&D Consultancy CGU
Based on an average revenue growth rate over the next 5 years of 5.1%, the net present value of future cash flows exceeds the carrying value 
of the CGU, as such no impairment has been recorded.
A sensitivity analysis using reasonably possible changes in key assumptions has been performed. None of these changes result in the value 
of goodwill allocated to R&D Consultancy being in excess of its recoverable amount and therefore no sensitivity analysis is presented.
Leatherhead Research CGU
Based on an average revenue growth rate over the next 5 years of 2.5%, the net present value of future cash flows exceeds the carrying value 
of the CGU, as such no impairment has been recorded.
A sensitivity analysis using reasonably possible changes in key assumptions has been performed. None of these changes result in the value 
of goodwill allocated to Leatherhead Research being in excess of its recoverable amount and therefore no sensitivity analysis is presented.
When assessing the recoverability of the Epsom freehold property, this has been reviewed as part of the Leatherhead CGU. The Leatherhead 
Food Research business uses the Epsom property for office and kitchen space. There were no recoverability issues raised as part of this review.
TSG America CGU
Based on an average revenue growth rate over the next 5 years of 4.1%, the net present value of future cash flows exceeds the carrying value 
of the CGU, as such no impairment has been recorded.
A sensitivity analysis using reasonably possible changes in key assumptions has been performed. None of these changes result in the value 
of goodwill allocated to TSG America being in excess of its recoverable amount and therefore no sensitivity analysis is presented.
TSG Europe CGU
Based on an average revenue growth rate over the next 5 years of 4.3%, the net present value of future cash flows exceeds the carrying value 
on the CGU, as such no impairment has been recorded.
A sensitivity analysis using reasonably possible changes in key assumptions has been performed. None of these changes result in the value 
of goodwill allocated to TSG Europe being in excess of its recoverable amount and therefore no sensitivity analysis is presented.
Frontier Smart Technologies Group CGU
Based on an average revenue growth rate over the next 5 years of 13.8% , the net present value of future cash flows exceeds the carrying 
value of the CGU, and as such no impairment has been recorded.
A sensitivity analysis using reasonably possible changes in key assumptions has been performed. None of these changes result in the value 
of goodwill allocated Frontier Smart Technologies being in excess of its recoverable amount, as such no impairment has been recorded.
CMS2 CGU
Based on an average revenue growth rate over the next 5 years of 2.9%, the net present value of future cash flows exceeds the carrying value 
of the CGU, as such no impairment has been recorded.
A sensitivity analysis using reasonably possible changes in key assumptions has been performed. None of these changes result in the value 
of goodwill allocated to CMS2 being in excess of its recoverable amount and therefore no sensitivity analysis is presented.
TPG Services CGU
Based on an average revenue growth rate over the next 5 years of 2.8%, and gross margin improvement of 6.3% from that achieved in 
2024, the net present value of future cash flows exceeds the carrying value of the CGU by £5.7 million and as such no impairment has been 
recorded.
There has been management action in TPG Services to reduce some legacy, low margin defence revenue contracts.  This has led to an 
overall forecast decrease in revenue within the CGU, with the intention of improving future margin.  The forecast expects margin to improve, 
however should the transition be slower or less effective than anticipated, revenue and margin may not be at the levels forecast (which may 
in turn lead to a potential impairment).  
Sensitivity analysis using reasonably possible changes in key assumptions has been performed. With all other base forecast assumptions 
remaining constant, a sensitivity was modelled where no gross margin improvement was achieved over the forecast period.  In this case, 
the business would need to achieve a compound annual revenue growth rate of 10.3% (from a conservative 2025 forecast) to avoid a 
potential impairment position. Alternatively, a sensitivity was modelled where revenue and the other forecast base assumptions remained 
constant, showing that a 6% increase in gross margin (on 2024) would be needed to avoid a potential impairment position. In both modelled 
scenarios, there would be further actions management could take to maintain and improve margin.

Freehold land and buildings include two properties in the UK.
The Epsom property is held at cost less accumulated depreciation. Included within land and buildings for the Group is freehold land to the 
value of £500,000 (2023: £500,000) which has not been depreciated.  During the year ended 31 December 2016, the property was brought 
into use from which point depreciation commenced. This property was acquired solely for the use of Science Group. This property was last 
formally valued by BNP Paribas Real Estate in December 2023 to a range of between £3.9 million (subject to the assumption of full vacant 
possession) and £7.6 million (under a sale and leaseback scenario).
The Harston property is held at cost less accumulated depreciation. Included within land and buildings for the Group is freehold land to 
the value of £1,360,000 (2023: £1,360,000) which has not been depreciated.  Cumulative interest capitalised up to 31 December 2003 was 
£340,000.  No further interest has been capitalised.  The Harston property was last formally valued during December 2023 by BNP Paribas 
Real Estate. Under the assumptions used, including tenant covenant strength and market rents, the indicative valuation range for the 
property was between £13.0 million (subject to the assumption of full vacant possession) and £24.0 million (under a sale and leaseback 
scenario).
The Epsom and Harston buildings are depreciated using the straight-line method to allocate their cost less their residual values over their 
estimated useful lives of 25 years. The residual values of the properties are based on estimates of the amounts the Group would receive 
currently for the properties if they were already of an age and in the condition expected at the end of their useful lives. The residual values 
are reviewed annually to ensure that they do not exceed the estimated market values of the properties.
The Harston property generated third party rental and associated income of £633,000 (2023: £819,000). Of this income, £363,000 (2023: 
£481,000) was rental income and £270,000 (2023: £338,000) was associated income. Associated income includes, but is not limited to, 
utilities, cleaning, and general maintenance.
The total space on the Harston site available for business use is 97,000 sq. ft. Of this space, the average total space let to third parties during 
2024 was 15,100 sq. ft. (2023: 21,000 sq. ft.). The leases to tenants are typically for between 24 and 60 months term and normally have a 
termination notice period of 3 to 12 months. An average of 47,800 sq. ft. (2023: 47,800 sq. ft.) was used by the Group during the year for 
its business activities including office space and laboratory space and 22,800 sq. ft. are common areas. The remaining space of 5.400 sq. ft. 
(2023: 5,400 sq. ft.) was vacant during the year.
Given the continuing rental values and occupancy rates the Directors do not believe that the combined carrying value of the Harston and 
Epsom properties of £20.8 million (2023: £21.0 million) is significantly different to its fair value. 
The Term Loan with Lloyds Bank plc is secured on the Harston and Epsom properties. 
Science Group plc, the Company, had fixed assets with a net book value of £306,000 at 31 December 2024 (£29,000 at 31 December 2023).
Residual values have been estimated for the Epsom and Harston properties based on estimates of the amounts the Group would receive 
currently for the properties if they were already of an age and in the condition expected at the end of their useful lives. The residual values 
are reviewed annually to ensure that they do not exceed the estimated market values of the properties. The property book values have been 
considered in comparison to third party valuation reports as well as value in use to the Group. Taking into account these valuation indicators, 
the Directors are comfortable the book values are appropriately stated and hold up to a robust level of sensitivity stress testing. 
On 19 March 2025 a refinancing of the existing Term Loan which is supported by the Epsom and Harston properties was announced. Further 
details can be found in Note 29.

*	 Capital contributions to subsidiaries are in relation to share-based payment charges for employees of the subsidiaries.
**	From August 2021, the Group commenced on-market purchases of shares in TP Group plc, increasing its shareholding to 29.21% as at 31 December 2022. The Group held an associate 
shareholding in TP Group plc until 26 January 2023, at which point Science Group plc acquired the remaining shares in TP Group plc and it became a subsidiary undertaking. 
For the period from 1 January 2023 to 26 January 2023, when TP Group plc was an associate undertaking, it had revenue from continuing 
operations of £2,574,000 and there was a loss in the period of £859,000. Science Group plc’s share of associate loss in this short period was 
£169,000. 
The investment in Frontier Smart Technologies Limited, is held at a carrying value of £13.7 million (2023: £13.5 million). In 2023, Frontier 
Smart Technologies Limited was impacted by the economic downturn in consumer electronics, compounded by overstocking in the 
distribution channel related to the post-Covid supply chain imbalances. There was a partial recovery for Frontier Smart Technologies 
Limited in 2024 and future forecast cash flows for this investment assume this to continue.  When assessing for impairment, management 
considered the possibility of a slower than anticipated market recovery. If compound revenue growth is 3.7% less than forecast, an 
impairment of the investment would arise. There would however be further actions management could take to maintain and improve 
margin. This is in respect of Science Group plc Company only and would have no impact on the Group results.

The Group applies the IFRS 9 simplified model of recognising lifetime expected credit losses for all trade receivables and amounts 
recoverable on contracts as these items do not have a significant financing component. 
The ECLs are based on the payment profile for sales over the past 48 months before 31 December 2024 and 31 December 2023 respectively 
as well as the corresponding historical credit losses during that period. The historical ECLs are adjusted to reflect current and forwarding 
looking macroeconomic factors affecting the customer’s ability to settle the amount outstanding.
Trade receivables and amounts recoverable on contracts are written off (i.e. derecognised) when there is no reasonable expectation of 
recovery. 
In relation to amounts owed by Group Undertakings, based on historical experience and informed credit assessment, the ECL is not material.

Dilapidation provisions have been recognised at the present value of the expected obligation. These discounts will unwind to their 
undiscounted value over the remaining lives of the leases via a finance charge within the Income Statement.
The average remaining life of the leases as at 31 December 2024 is 3.5 years (2023: 2.7 years).
The restructuring provision relates to the costs associated with the closure of some non-trading Group entities.
Legal provisions reflect the best estimate of the future cost of responding to potential legal claims.
The other provision relates to a provision for the employer’s NIC liability on share options that have vested (or the proportion that have 
vested). As the employee is contractually responsible for the employer’s NIC on any share options exercised and is required to remit this sum 
to the Company prior to the share options being exercised, a corresponding asset is recognised in current assets. It also includes provisions 
made in respect of product and services deliveries that include warranty provisions.

sums of cash consideration in any future business acquisitions, and in limited circumstances to satisfy shareholder demand which market 
liquidity is unable to meet. No dividend or other distribution may be made to the Company in respect of the treasury shares. 
The total charge relating to employee share-based payment plans, all of which related to equity-settled share-based payment transactions,

The Group has an employee share option scheme which awards options to certain employees. The Performance Share Plan (‘PSP’) sets the 
target based on EPS over 3 years. The vesting period is 3 or 5 years. The Enhanced Executive Incentive Addendum (‘EEI’) options are for 
Directors and senior managers. The vesting conditions for these awards is based on the share price. The vesting period for these awards is 
5 years.
During the year ended 31 December 2024, share options were issued under the PSP and EEI.
The options outstanding at 31 December 2024 had a weighted average contractual life of 8.0 years (2023: 8.0 years).
Included within the total outstanding options at 31 December 2024 are 404,490 options which are exercisable (2023: 414,990). The weighted 
average exercise price of exercisable options at the end of the year was 1.0 pence (2023: 1.0 pence).
Options exercised during the year had a weighted average share price at the date of exercise of 421.0 pence (2023: 400.0 pence).
Exercise of an option is subject to continued employment and normally lapses upon leaving employment.
The fair values of options granted under the PSP in 2024 were determined using a variation of the Binomial Option Pricing model that 
takes into account factors specific to the share incentive plans including performance conditions. The performance conditions have been 
incorporated into the measurement by means of actuarial modelling. One vesting condition attached to options granted in the year is such 
that 100% of the options vest dependent on the Company achieving earnings per share targets. For options granted in the year, a risk-free 
rate of 4.29% and a dividend yield factor of 1.91% has been used. The share price on the date the options were granted was 419.0 pence. 
The other principal assumptions used in the valuation are set out in the table below
The fair values of options granted under the EEI in 2024 were determined using the Monte Carlo valuation model that takes into account 
factors specific to the share incentive plans including performance conditions. The performance condition attached to options granted in the 
year is such that 100% of the options vest dependent on the Company achieving a share price hurdle target. The performance condition has 
been incorporated into the measurement by means of actuarial modelling. For options granted in the year, a risk-free rate of 3.73% and a 
dividend yield factor of 1.74% has been used for the options issued. The share price on the date the options were granted was 461.0 pence. 
The other principal assumptions used in the valuation are set out in the table below. The underlying expected volatility was determined by 
reference to historical data of the Company’s shares over the vesting period.

Science Group plc, the Company, had no bank borrowings at the start nor the end of the year.
During the year ended 31 December 2016, the Group entered into a 10-year fixed Term Loan of £15.0 million which is secured on the 
freehold properties of the Group and on which interest is payable based on SONIA plus 2.6% margin. During the year ended 31 December 
2019, the Group increased this existing loan by £4.8 million to £17.5 million on similar terms. The repayment profile of the loan is £1.2 million 
per annum over the term with the remaining balance repaid on expiry of the loan in 2026. Costs directly associated with entering into the 
loan (including the loan increase), have been offset against the balance outstanding and are being amortised over the period of the loan.
During the year ended 31 December 2020, the Group drew a further £1.5 million of loan funds from the £17.5 million existing loan 
agreement. This was on similar terms and with no change to the loan repayment profile (i.e. the quarterly repayments remained the same 
and the loan balance remains payable on 30 September 2026). Costs directly associated with entering into the additional loan have been 
offset against the balance outstanding and are being amortised over the period of the loan. 
At 31 December 2024, the amount outstanding on the Term Loan was £11.8 million (2023: £13.0 million). 
The carrying amount of the Term Loan is considered to be a reasonable approximation of the fair value.

(b) Revolving Credit Facility
In December 2021 Science Group plc signed a Revolving Credit Facility (‘RCF’) with Lloyds Bank plc in order to provide additional capital 
resources to enable the execution of the Group’s acquisition strategy. The RCF is for up to £25.0 million, with an additional £5.0 million 
accordion option. The original agreement was for a term of four years, however an option to extend the term by an additional year was taken 
by the Group in December 2023 (meaning the term end date is now December 2026). The margin on drawn sums is 3.3% over the Sterling 
Overnight Index Average (‘SONIA’) and is 1.1% per annum on undrawn amounts. Drawn amounts are secured on the Group’s assets by 
debentures. The RCF is in addition to the Group’s existing Term Loan.

(b) Revolving Credit Facility continued
The RCF has two financial covenants with which the Group needs to comply if the facility is drawn: (i) the Group’s net leverage, as defined 
as the net debt divided by the rolling 12 month EBITDA, should not exceed 2.5; and (ii) the Group’s interest cover, as defined as the rolling 
12 month EBITDA divided by the rolling interest payments on all borrowings, should not be less than 4.0. Reporting is on a 6 monthly basis 
unless the net leverage exceeds 2, in which case reporting moves to quarterly until net leverage returns to below 2 again. For the term of the 
RCF, the previous covenants for the Term Loan are superseded by the covenants of the RCF and will not apply.

On 19 March 2025 a refinancing of the existing RCF was announced. Further details can be found at Note 29.
(c) Hedge accounting 
In order to address interest rate risk, the Group entered into phased interest rate swaps in order to fully hedge the loan resulting in a 10-
year fixed effective interest rate of 3.5%. The interest rates on the swaps range from 0.4% to 1.3% which when combined with the margin on 
the loan economically fix the finance cost at 3.5%. 
Hedge effectiveness is determined at inception of the hedge relationship and at every reporting period end through the assessment of the 
hedged items and hedging instrument to determine whether there is still an economic relationship between the two. The critical terms of 
the interest rate swaps entered into exactly match the terms of the hedged item. As such the economic relationship and hedge effectiveness 
are based on the qualitative factors and the use of a hypothetical derivative where appropriate. 
Hedge ineffectiveness may arise where the critical terms of the forecast transaction no longer meet those of the hedging instrument, 
however the hedged items and the hedging instrument relationship matches one to one. For example, if the payment of the loan and the 
interest are transacted at different times, the hedge will become ineffective however the timing of the payments are within the control of 
the Group. All derivative financial instruments used for hedge accounting are recognised initially at fair value and reported subsequently 
at fair value in the consolidated statement of financial position. To the extent the hedge is effective, changes in the fair value of derivatives 
designated as hedging instruments in cash flow hedges are recognised in other comprehensive income and included within the cash flow 
hedge reserve in equity. Any ineffectiveness in the hedge relationship is recognised immediately in profit or loss. At the time the hedged item 
affects profit or loss, any gain or loss previously recognised in other comprehensive income is reclassified from equity to profit or loss and 
presented as a reclassification adjustment within other comprehensive income. If a forecast transaction is no longer expected to occur, any 
related gain or loss recognised in other comprehensive income is transferred immediately to profit or loss. If the hedging relationship ceases 
to meet the effectiveness conditions, hedge accounting is discontinued, and the related gain or loss is held in the equity reserve until the 
forecast transaction occurs. 
The Group has adopted hedge accounting for the interest rate swaps under IFRS 9 Financial Instruments, and the loss on change in fair 
value of the interest rate swaps of £0.3 million (2023: loss of £0.5 million) was recognised in other comprehensive income. The fair value of 
the swap at 31 December 2024 was an asset of £0.6 million (2023: asset of £0.9 million).
The effects of the interest rate swaps on the Group’s financial position and performance are as follows:

The notional amount on the interest rate swaps reduces in line with the repayment of the Term Loan, so an effective hedge remains 
throughout the term of the loan. There are 4 active swaps in place at 31 December 2024, totalling £11.8 million. Of this total, £0.8 million will 
mature in September 2025 and the remaining balance of £11.0 million will mature in September 2026.

The interest rate swaps are used to mitigate interest rate risk (see Note 23).
The Group uses currency exchange instruments to mitigate foreign exchange rate exposure arising from highly probable forecast sales in US 
Dollars. 
Hedge effectiveness is determined at inception of the hedge relationship and at every reporting period end through the assessment of the 
hedged items and hedging instruments to determine whether there is still an economic relationship between the two.
The critical terms of the currency exchange instruments exactly match the terms of the hedged item. As such the economic relationship and 
hedge effectiveness are based on the qualitative factors and the use of a hypothetical derivative where appropriate.
Hedge ineffectiveness may arise where the critical terms of the forecast transaction no longer meet those of the hedging instrument, for 
example if there was a change in the timing of the forecast sales transactions from what was initially estimated or if the volume of currency in 
the hedged item was below expectations leading to over-hedging.
The hedged items and the hedging instrument are denominated in the same currency and as a result the hedging ratio is always one to one.
All derivative financial instruments used for hedge accounting are recognised initially at fair value and reported subsequently at fair value in 
the consolidated statement of financial position.
To the extent the hedge is effective, changes in the fair value of derivatives designated as hedging instruments in cash flow hedges are 
recognised in other comprehensive income and included within the cash flow hedge reserve in equity. Any ineffectiveness in the hedge 
relationship is recognised immediately in the income statement.
At the time the hedged item affects profit or loss, any gain or loss previously recognised in other comprehensive income is reclassified from 
equity to profit or loss and presented as a reclassification adjustment within other comprehensive income.
If a forecast transaction is no longer expected to occur, any related gain or loss recognised in other comprehensive income is transferred 
immediately to profit or loss. If the hedging relationship ceases to meet the effectiveness conditions, hedge accounting is discontinued, and 
the related gain or loss is held in the equity reserve until the forecast transaction occurs.

b. Leases as lessor
The Group leases out some of the Harston site to third parties on leases which normally have a termination notice period of 3 to 6 months 
and typically for a 36-month term.
The leases are classified as operating leases from a lessor perspective because they do not transfer substantially all the risk and rewards to 
the ownership of the assets. Note 15 sets out information about the Harston leases and rental income recognised by the Group during the 
periods presented.
The following table sets out a maturity analysis of lease payments, showing the undiscounted lease payments to be received after the 
reporting date.

28. Critical accounting estimates and judgements
Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of 
future events that are believed to be reasonable under the circumstances. Science Group makes estimates and assumptions concerning the 
future. The resulting accounting estimates will, by definition, seldom equal the related actual results. The estimates and assumptions that 
have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are 
discussed below.
(a) Critical accounting estimate
Assessment of the percentage of completion of long-term contracts
The Group’s revenue recognition policy, which is set out in Note 2.18, requires forecasts to be made of the outcomes of long-term design 
and manufacture contracts. This requires estimates of labour hours and rates, and material costs to determine forecast costs to completion 
and therefore revenue recognition on each long-term contract. Where actual costs incurred differ to forecast costs, or where forecast cost 
estimates change, the assessment of the percentage of completion of long-term contracts will be affected and therefore revenue and profits 
or losses recognised impacted. Estimates are reviewed regularly throughout the contract life and adjustments are made based on the latest 
available information.
As at 31 December 2024, at the Group level, the amounts due from contract customers and amounts due to contract customers amounted 
to £4,283,000 and £17,863,000 respectively as set out in Note 5 although only the ‘Systems – Submarine Atmosphere Segment’ undertakes 
material long-term contracts.
As at 31 December 2024, the amounts due from contract customers and amounts due to contract customers in respect of the Systems 
– Submarine Atmosphere Management Segment amounted to £3,783,000 and £4,381,000 respectively. Given the nature of long-term 
contracts undertaken by the business, the Forecast Costs to Complete (‘FCC’) are closely monitored with weekly and monthly project review 
meetings. In the event that FCC were 10% higher than forecast at 31 December 2024 the revenue and adjusted operating profit for the year 
ended 31 December 2024 would have been £333,000 lower.
Assessment of contracts subject to Ministry of Defence ('MOD') audit
It should be also noted that revenue recognisable on work performed under MOD procurement contracts is subject to audit of rates 
applied for each year by MOD’s audit team. The Group judgement is not to recognise any non-finalised uplifts until the audit has been fully 
completed as it is substantive in nature, and the outcome could lead to significantly different rates being applied through contract pricing 
methodology. As a result of the substantive audits being complete, there may be a one-off adjustment to the revenue recognised in respect 
of these projects. 
The Group has considered the nature of the estimates involved in deriving these balances and concluded that it is possible that outcomes 
within the next financial year may be different from the assumptions applied at 31 December 2024, which could require a material 
adjustment to revenue and profits or losses recognised and the carrying amounts of the related assets and liabilities in the next financial 
year.  
Impairment of non-financial assets and goodwill
In assessing impairment, the Group estimates the recoverable amount of each asset or cash generating unit based on expected future 
cash flows and uses an interest rate to discount them. Estimation uncertainty relates to assumptions about future operating results and the 
determination of a suitable discount rate (see Note 14). 
(b) Significant accounting judgement
Accounting for freehold property at Harston Mill
Science Group owns and maintains the freehold property at Harston Mill for use in the supply of its business services and for administrative 
purposes. Whilst there is remaining space on site not required to fulfil these activities, Science Group lets out space to third party tenants. 
The revenues and costs attributable to this activity are disclosed as third party property income activities within the business segment 
disclosures. It is not accounted for as an investment property, the reasons being:
(i)	
the third party leases include the use of common areas and because of this the areas that are leased to third parties could not be sold 
separately.
(ii)	
the leases normally have notice periods of no more than six months giving Science Group the flexibility to start using the areas if 
required, i.e., the leased areas are not held for capital appreciation or a return of investment through rental income.
Further information about the space let out to third party tenants is included in Note 15.
Recognition of deferred tax assets
The Group recognises deferred tax assets on carried forward unused tax losses to the extent that it is probable future taxable profits will be 
available against which the tax losses can be utilised. 
At 31 December 2024, the Group has recognised deferred tax assets amounting to £1.8 million (2023: £3.6 million) related to tax losses 
carried forward (see Note 11). The deferred tax asset value is based upon an estimate of the next 2 years of respective taxable profits (or a 
longer period where the use of losses is less restrictive), this being the period over which the Group has reasonable confidence in estimating 
future taxable profits that meet the evidence requirement for deferred tax asset recognition purposes. 
29. Post balance sheet events
Investment in Ricardo plc
On 28 February 2025 the Group announced an investment in Ricardo plc. Over the period 16 February 2025 to 27 February 2025, the Group 
acquired 5.3 million shares in Ricardo plc equivalent to 8.5% of the voting rights. These shares were acquired at a total cost of £12.2 million 
(including brokerage fees) at an average cost of 231 pence per share.  
Share purchases continued and by 19 March 2025 the Group had increased its shareholding to 10.1 million shares, equivalent to 16.2% of 
the voting rights. The total cost of shares acquired to date was £23.3 million (including brokerage fees). This investment was funded from the 
Group’s existing cash resources.
The Group will engage with the Ricado plc board and its major shareholders in relation to managing this investment.
Refinancing of existing bank facilities
On 19 March 2025 the Group announced it had agreed new bank borrowing facilities with Lloyds Bank plc. The existing Term Loan and RCF 
were scheduled to expire in September 2026 and December 2026 respectively. 
There are now two new Term Loans for a combined value of £12.0 million, each for 10 years expiring in March 2035. Each loan is secured 
solely and individually against the Group’s freehold properties: one loan to the property in Harston, near Cambridge, and, a second, 
independent loan to the property in Epsom, Surrey. 
The new, increased RCF is for £30.0 million, for a period of 5 years expiring in March 2030, an increase of £5.0 million over the 2021 RCF. The 
RCF also has a £10.0 million accordion, a further increase of £5.0 million over the 2021 RCF. The RCF is currently undrawn and therefore no 
covenants apply.
