About SRT Marine Systems plc 
Our technologies and 
products enable our 
customers to solve important 
maritime issues such as 
navigation safety, national 
security, sustainable fishing 
and environment protection. 
Every day, hundreds of thousands of marine stakeholders 
across the world, from boat owners and operators to 
national coast guards, security and safety agencies and 
fishery regulators rely upon SRT developed and supplied 
products and systems to provide them with the data, 
insight and operational tools they need to effectively and 
efficiently fulfil their objectives. 
Our products range from digital navigation safety 
transceivers, which are fitted to boats and buoys and 
enable them to instantly see and identify each other with 
dramatic enhancements in navigation safety and a key 
enabler in the coming autonomous era, to national scale 
integrated maritime surveillance systems that are able to 
simultaneously track, identify and characterise hundreds 
of thousands of targets in real time and enable authorities 
to effectively securitise their sovereign waters and manage 
national fishing activities sustainably. 
The digitising of the marine domain is in its early stages, 
and through years of strategic technology, product and 
market investment, SRT has become an established 
global leader and is now in a position to maximise the 
opportunities that the continuing development of this 
substantial market of over 30 million vessels will yield.

Annual Report and Financial Statements | 2024
SRT Marine Systems plc
Chairman’s Statement
The financial period has been one of significant investment 
in our technologies, products and capacity in preparation to 
simultaneously support multiple substantial system projects 
and launch our NEXUS marine VHF/AIS radio system. These 
investments place SRT in a transformational situation for the 
new financial year and the years ahead.
Previously expected substantial revenues from new 
system contracts and our new NEXUS transceiver will now 
commence in the new financial year which has resulted in 
our revenues for the extended 15 month financial period, 
ending 30 June 2024, being much lower than expected at 
£14.8m (2023: £30.5m) of which transceivers generated 
£13.3m and systems £1.5m. Gross profit margin was 
28% (2023: 36%) with the reduction due to an increase in 
system project costs associated with project finalisation 
and warranty and support activities. Combined with the 
additional necessary preparation investments for multiple 
new system projects, this has resulted in a loss after tax 
of £13.7m (2023: profit £0.1m). As at period ended 30 
June 2024, cash was £2.8m (March 2023: £2.2m). As at 
period ended 30 June 2024, cash was £2.8m (March 2023: 
£2.2m). Following the period end, we are in the process of 
finalising a significant financing transaction which includes 
an equity fund raise of £8.5m that will go for shareholder 
approval in early December.
Our transceivers business is the global leader in digital 
maritime navigation safety transceivers. These are used 
by boats, both commercial and leisure, and on marine 
infrastructure such as buoys, to enable automated 
communication and enhance navigation safety day and 
night and in all weathers. Revenues for the 15-month period 
were £13.3m, generating a gross profit margin of 49%. 
We are pleased to report that following the Covid supply 
chain issues which caused our cost and consequently 
sales prices to spike, normality has returned resulting in 
both average cost and selling prices reducing, along with 
normalised margins and manufacturing lead times. 
We distribute our transceiver products via a growing global 
network of approximately 5,000 value added resellers 
(VARs) as well as direct to end users, both under our 
own brands and as an OEM supplier under their brands. 
This is a hugely valuable network which provides us with 
global market penetration and therefore during the period 
we have continued to take care of this network through 
improving product training and knowledge and preparing 
them for the coming launch of NEXUS.
In our vessel transceivers business, we primarily sell AIS 
navigation devices. The long-term underpinning demand 
drivers for these are well established with a steady 
build up of regulations around the world, coupled with a 
standardisation of AIS as an important navigation system 
when vessels are first bought. During the period we saw 
sales in our OEM business fall, due to the reduction in 
brand-new boat purchases which is the primary source of 
new business for ‘packaged’ branded marine electronics 
systems. We expect to see a further fall and then 
stabilisation in the new year reflecting the reduced market 
demand for new boats. However, in the retro-fit market, we 
saw volumes increase with revenues about the same as 
the previous year due to the per unit price normalisation 
following the Covid spike. We expect to see the trend of 
increasing volumes and therefore revenues continue in 
future years as more and more boat owners fit and use AIS. 
Our DAS transceivers division provides specialist digital 
Aids to Navigation transceivers which are used on buoys 
and other marine infrastructure to digitally mark them 
and enable enhanced navigation safety and autonomy. 
With most of the world’s navigation infrastructure still 
being analogue we see a substantial and long-term 
market opportunity in which we have invested heavily 
to develop the necessary technology, products and 
market distribution. Our focus has been to work with our 
distribution network and relevant waterway authorities 
to develop DAS deployment strategies and sales 
opportunities. We are starting to see the fruits of this 
strategy with revenues for the 15-month financial period 
amounting to £2.4m (year to 31 March 2023: £1.2m), whilst 
maintaining a healthy 81% gross profit margin. Looking 
to the future, for the first time we now have an identified 
sales order pipeline which we are targeting and believe we 
will continue to see this segment grow from its current low 
base.

Annual Report and Financial Statements | 2024
SRT Marine Systems plc
Development wise, our focus has been the completion 
of NEXUS which is a new combined voice and data (VHF/
DSC/AIS) marine communications transceiver system, 
with innovative mobile device integration and functionality. 
This takes us into a new and significant marine electronics 
market segment. I am pleased to report that NEXUS has 
entered pre-production and is in its final phases of user 
testing and refinement. Following a soft launch in 2023 
to some of our dealer network, for the first time we have 
a forward order book for a new product. In November 
2024, NEXUS was officially launched under the em-trak 
brand as the X100. Our global VAR network enables us to 
achieve global market presence instantly with shipping to 
commence during early 2025. 
As a new product we will cautiously limit initial sales in 
order to garner early user feedback and implement market 
derived ideas before ramping production. Therefore, whilst 
market indications suggest strong demand, during the 
initial 6 to 12 months, we will control sales. 
Our systems business delivers sophisticated maritime 
surveillance, intelligence and management systems to 
national agencies such as Coast Guards, Border Agencies 
and Fishing Authorities worldwide. Under our Sovereign 
Partnership program we have built relationships with four 
countries in Asia and the Middle East and completed 
projects worth £50m, and have a further £320m of 
contracts signed which are now starting. Looking to next 
year and beyond we have a growing pipeline of prospective 
new contract opportunities with both existing and new 
customers which today is valued at approximately £1.2bn. 
We believe this global market is at the start of its growth 
and development on the basis that in the future most 
countries with a coastline and sovereign marine areas 
will want to have independent next generation maritime 
surveillance capabilities.
We had expected some of the £320m of new contracts 
to commence during the current financial period, and 
therefore took action to prepare. This has entailed the 
forward purchase of certain equipment ready to ship 
against early contractual milestone, and the build-up of 
additional implementation capacity.  However, due to 
unexpected extended customer contract administrative 
processes the commencement of these contracts was 
delayed into the new financial year. As of the publication 
of this report, we have commenced work on our recently 
announced $213m contract with the Kuwait Ministry 
of Interior and are pleased to advise that the final 
administrative processes on the other contracts are 
nearly complete and thus expect work to commence 
at the beginning of the second half of the new financial 
year. Whilst the combination of increased overheads and 
delayed revenues has resulted in a significant loss for the 
period, these extensive preparations have placed us in 
a good position to successfully implement these multiple 
system projects within the expected two year time frame. 
During the period we also continued to progress 
discussions with many new opportunities in our Validated 
Sales Pipeline (VSP) which stands at an estimated £1.2bn. 
We expect several of these to convert into contract during 
2025 and further conversions, and new additions thereafter. 
It is clear to us that we are now entering a new phase of 
significant growth driven by these existing contracts, 
follow on contracts and new ones we expect to convert. 
This is the result of many years of investments in our core 
technologies, products and capacity to successfully deliver. 
During the period, we completed several equity raises – 
in June 2023 we completed a raise of £5.4m followed by 
a further £10.5m in December 2023, with Ocean Infinity 
strategically acquiring a stake in SRT and we are starting 
to leverage our respective complementary products and 
technologies. In November 2024, we successfully raised 
a further £8.5m, with Ocean Infinity increasing their stake 
in SRT and a representative will join our board once the 
necessary shareholder approvals are obtained for this 
transaction. This last transaction is expected to complete 
in early December 2024. These transactions have provided 
us with the working capital to sustain our product and 
market investments and be in the strong position we 
are in today with £320m of contracts and the capacity 
and capability to deliver to the standards and timescales 
expected by our customers. 
Outlook
Our strategy has been all about investing in technologies 
and products based upon our expectation that the global 
marine market for a new generation of digital navigation 
and surveillance will be very significant. This has entailed 
a long and continuous period of heavy investment in order 
for us to have the products and develop the market. We 
now have the products, the global distribution and signed 
contracts of over £320m, along with a significant pipeline 
of future opportunities. This places us in an excellent 
position to start to realise favourable financial performance 
in the new year and consistently in the following years. 
In the immediate two years we will be executing on our 
existing contracts and pushing forward with growing our 
transceiver business through our 5,000 VARs. Furthermore, 
we expect this to be augmented by conversions from 
our £1.2bn pipeline of new contract opportunities. We 
therefore believe the coming years will be transformational.

Annual Report and Financial Statements | 2024
SRT Marine Systems plc
Strategic Report
for the 15 months ended 30 June 2024
The directors present their strategic report for the 
15 months ended 30 June 2024.
Business review
The principal activity of the SRT Marine Systems plc, 
“the Group”, is the development and supply of integrated 
maritime surveillance, monitoring, management and 
safety systems used by coast guards, fishery authorities, 
infrastructure and vessel owners for the purposes of 
managing and controlling their maritime domain.
The financial Key Performance Indicators (KPIs) used by 
the Board to monitor progress are revenue growth, gross 
margin, profit before tax and cash flow. These are used 
because they best indicate performance against the 
Group’s strategic objective of delivering profitable growth 
which in turn will drive shareholder value. Non-financial KPIs 
used include status of customer and development projects 
against milestone targets. Performance against these 
metrics has been discussed in the Chairman’s Statement 
on pages 6–7. 
Principal risks and uncertainties
The key risks and uncertainties faced by the Group are:
Nature of systems customers 
These customers tend to be governments and thus can 
be subject to significant risk, including but not limited to 
the forecasting of project commencement dates and 
project delivery schedules, political and financial change 
and uncertainty, sudden cancellation and or changes to 
contracts without the possibility for redress, negotiation 
and or compensation. Furthermore, payment terms are 
frequently extended and variable and in the event of non-
payment may not be collectable.
The Group seeks to manage this risk by obtaining a deep 
understanding of our markets, end customers and local 
partners which is achieved through extensive and close 
co-operation.
System execution risk
The implementation of a system contract contains a wide 
range of execution risks including on time delivery of the 
Group’s system and products to the desired customer 
specification and quality levels. These risks are mitigated 
through forming long-term partnerships with local 
installation partners and investing in customer support and 
system project delivery teams. 
Attracting and retaining employees with 
appropriate skills 
The Group’s ability to execute its strategy is dependent 
on the skills and abilities of its staff and without these 
appropriate skills the Group risks not being able to 
effectively deliver its products and systems to its 
customers. The Group manages this risk by undertaking 
ongoing initiatives to foster good staff engagement, by 
investing in its HR function and ensuring that remuneration 
packages are competitive in the market.
Dependence on manufacturers, suppliers and 
service providers
The Group does not engage in its own manufacturing 
processes and relies on a limited number of manufacturers 
and suppliers. This includes reliance on installation 
partners for its systems business projects. The Group 
mitigates this risk by its supply chain team visiting its 
manufacturing partners on a regular basis together with 
other key suppliers to foster good relationships, address 
operation concerns and devise strategic plans to ensure 
the enduring prosperity of the partnership. The systems 
delivery team communicate with its in-country installation 
partners on a very regular basis to ensure a collaborative 
approach and that common goals are established and 
achieved for the successful delivery of customer projects.

SRT Marine Systems plc
Section 172 (1) Statement
Each individual director must act in the way he considers, 
in good faith, would be the most likely to promote the 
success of the Group for the benefit of its members as a 
whole, and in doing so have regard to:
•	
long-term consequences of any decisions
•	
the interests of the Group’s employees
•	
the need to foster business relationship with suppliers, 
customers and others
•	
the impact of the Group’s operations on the 
community and the environment
•	
the need to maintain a reputation for high standards of 
business conduct and act fairly between members of 
the group
Key issues 
Key issues include the investment and delivery of key 
projects in the systems business in overseas territories. 
In all evaluations the need to foster important business 
relationships with customers and local in country suppliers 
are key considerations which we manage by visiting them 
face to face on a regular basis regardless of where they are 
located. During the period, we have completed a full social 
and environmental assessment for one of our systems 
projects and will use this as a template for future project 
assessments. We continue to maintain our anti bribery and 
corruption policy. This shows our continued endeavour for 
high standards of business conduct, health and safety and 
environmental compliance. 
Furthermore, the interests of our employees continues to 
be of paramount importance with the business having now 
transitioned to a flexible hybrid work location operating 
model to ensure the welfare of our employees. During the 
period, we have further invested in our human resources 
function and will intend to continue to implement further 
improvements over the coming year.
Stakeholders
Key stakeholders include shareholders, employees, 
customers and suppliers.
Methods of engagement
The Group uses a range of methods of engagement with 
stakeholders, ranging from formal structures to personal 
engagement. Shareholders are updated regularly on 
business activities via investor roadshows, quarterly on-line 
web casts, one on one communication with the executive 
directors and AGM presentations. 
The Group’s flat management structure allows personal 
interaction at all levels which facilitates communication 
within the organisation as well as externally with customers 
and suppliers. An “open door” culture is operated with all 
stakeholders. Employees have regular personal interaction 
with their line managers and the executive directors have 
annual targets set, against which formal assessments of 
performance is reviewed. All key suppliers and customers 
are personally met in order that business relationships can 
be fostered.
Investing for the future
We acknowledge that our chosen market places are still 
in their early stages and as a result we need to continue to 
invest in our organisation in order to meet the challenges 
that a growing market will bring. This will involve adding 
to our existing product and system portfolio as well as 
evolving our current technology offerings which is further 
discussed in the Chairman’s Statement.
Approved by the Board of Directors and signed on behalf of 
the Board on 29 November 2024.

Annual Report and Financial Statements | 2024
SRT Marine Systems plc
Statement of Directors’ Responsibilities 
in respect of the accounts
The directors are responsible for preparing the Strategic Report, 
Directors’ Report and the financial statements in accordance with 
applicable law and regulations.
Company law requires the directors to prepare financial 
statements for each financial year. Under that law the 
directors have elected to prepare the Group and parent 
Company financial statements in accordance with 
UK-adopted international accounting standards. 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 Company and 
of the Group and of the profit or loss of the Group for 
that period. In preparing these financial statements, the 
directors are required to:
•	
select suitable accounting policies and then apply 
them consistently;
•	
make judgments and accounting estimates that are 
reasonable and prudent;
•	
state whether UK-adopted international accounting 
standards have been followed subject to any material 
departures disclosed and explained in the financial 
statements; and
•	
prepare the financial statements on the going concern 
basis unless it is inappropriate to presume that the 
Company will continue in business.
The directors are responsible for keeping adequate 
accounting records that are sufficient to show and explain 
the Company’s transactions and disclose with reasonable 
accuracy at any time the financial position of the Company 
and enable them to ensure that the financial statements 
comply with the Companies Act 2006. They are also 
responsible for safeguarding the assets of the Group and 
Company and hence for taking reasonable steps for the 
prevention and detection of fraud and other irregularities. 
The directors are also responsible for ensuring that they 
meet their responsibilities under the AIM Rules.
The directors are responsible for the maintenance and 
integrity of the corporate and financial information included 
on the Company’s website. Legislation in the United 
Kingdom governing the preparation and dissemination of 
financial statements may differ from legislation in other 
jurisdictions.

Corporate Governance Report
for the 15 months ended 30 June 2024
The directors recognise the importance of, and are committed to, high 
standards of corporate governance. AIM companies are required to 
apply a recognised corporate governance code. 
Of the three widely recognised formal codes, the directors 
have decided to adhere to the Quoted Companies 
Alliance’s Corporate Governance code for small and 
mid-size quoted companies. The Group’s compliance with 
this code is summarised below and can be found in full on 
the Group’s website at: www.srt-marine.com/corporate-
governance.
Business model and strategy
SRT is a global leader in the provision of maritime domain 
awareness (MDA). Our products are used by mariners, 
infrastructure owners, coast guards and fishing authorities 
to enhance safety, security and management efficiency of 
maritime regions.
SRT’s strategy and business model is to address MDA 
market segments using a small set of innovative core 
technologies and products and systems which can 
be combined and customised into multiple product 
configurations and types each of which address different 
MDA market segments.
The key risks and challenges faced by the Group are set 
out in the Strategic Report on pages 8–9.
Risk management
The Board is responsible for the systems of internal control 
and risk management and reviewing their effectiveness. 
Furthermore, through the activities of the Audit Committee 
the effectiveness of these internal controls is considered 
annually.
A comprehensive budgeting process is completed once a 
year and is reviewed and approved by the Board. Revised 
forecasts are also produced on a monthly basis. The 
Group’s results, compared with the budget and forecast are 
reported to the Board on a monthly basis. 
Within the scope of the annual audit, specific financial risks 
are evaluated in detail, including those in relation to revenue 
recognition, recoverability of receivables and stock and 
intangibles valuation. 
SRT has published a share dealing policy on its intranet to 
seek the necessary approval from directors should they, or 
their families, plan to trade in the Group’s equities.
The Board of Directors
The members of the Board have a collective responsibility 
and legal obligation to promote the interests of the Group 
and are collectively responsible for defining corporate 
governance arrangements. Ultimate responsibility for the 
quality of, and approach to, corporate governance lies with 
the chair of the Board. 
The Board consists of seven directors of which four are 
executive and three are independent non-executives. The 
Board is satisfied that at present it has a suitable balance 
between independence on the one hand and knowledge of 
the company on the other.
During the 15 months ended 30 June 2024, there were six 
Board meetings and calls. Each director attended all the 
meetings and calls during the period, except Jean Francois 
Bonnin who missed one meeting.
The Board has an agenda of items to consider at each 
meeting subdivided into the key activities of the business, 
namely operations, product management, project delivery, 
sales and marketing and financial matters. Prior to the 
Board meeting a board pack of information is compiled by 
the executive directors and circulated around the Board 
together with the minutes from the previous meeting 
for approval and the monthly management accounts. 
The Board believes that the composition and breadth of 
experience of the board are appropriate for the Group at 
present and that its blend of relevant experience, skills and 
personal qualities and capabilities is sufficient to enable it 
to successfully execute its strategy. All Directors receive 
regular and timely information on the Group’s operational, 
sales and financial performance.
Biographies of the Board are set out in the Corporate 
Governance section of the Group’s website.

SRT Marine Systems plc
The Board is supported by three committees: audit, 
remuneration and nomination. 
Audit Committee
The Audit Committee comprises of Simon Barrell 
(Chairman) and Kevin Finn. It meets at least twice per 
year. The Audit Committee reviews the effectiveness of 
the internal controls of the business, as well as any key 
judgements made in the preparation of the interim and 
annual accounts and the effectiveness of the internal 
financial management. The audit planning meeting took 
place on 16 August 2024 and the meeting to review 
feedback from the 2024 audit took place on 28 November 
2024. 
Remuneration Committee
The Remuneration Committee comprises Simon Rogers 
(Chairman), Kevin Finn and Simon Barrell; it meets at least 
once a year. During the period, the Committee met to 
discuss the remuneration of the Executive Directors. The 
remuneration policy for Directors is set by the Board and 
is described below. It is determined by the Remuneration 
Committee within the framework of this policy. The 
remuneration of the Executive Directors is determined by 
the Remuneration Committee which consists entirely of 
Non-Executive Directors. The Remuneration Committee 
consults with Simon Tucker, the Group Chief Executive 
Officer, as appropriate with regard to its proposals relating 
to the remuneration of the Executive Directors.
The policy of the Remuneration Committee is to review 
the Executive Directors’ remuneration based on market 
practice within the Group’s market sector. The Group 
wishes to attract, motivate and retain key executives. 
Accordingly, its policy is to design remuneration packages 
which, through an appropriate combination of basic salary, 
performance related bonuses, share options, pension 
arrangements and certain benefits, reward executives fairly 
and responsibly for their individual contributions, whilst 
linking their potential earnings to the performance of the 
Group as a whole. The overall package, which is reviewed at 
least annually may contain the following elements:
a)	
Basic salaries
Basic salaries for Executive Directors are reviewed 
annually by the Remuneration Committee and are set 
at levels which reflect their performance and degree of 
responsibility.
b)	
Enterprise Management Incentive Share Option 
Scheme
The Group has had in place, since November 2005, 
an enterprise management incentive share option 
scheme under which awards are met at the discretion 
of the Remuneration Committee. The share options 
held by the Directors are set out in note 3.
c)	
Performance-related bonus 
The Remuneration Committee can award discretionary 
bonuses, which are linked to the achievement of 
demanding individual, business and corporate 
objectives.
d)	
Pension allowance
Simon Tucker elected not to join the Group’s Money 
Purchase Pension Scheme and in compensation for 
this the Remuneration Committee agreed to pay him 
the amount that the Group would have paid to the 
pension scheme on his behalf, for him to invest as he 
wishes.
e)	
Other benefits
Other benefits include private health insurance.
f)	
Non-Executive Directors
The Non-Executive Directors are independent 
of management and have no relationship which 
could materially interfere with the exercise of their 
independent judgement. The remuneration of the 
Non-Executive Directors is decided by the Executive 
Directors. 
Nomination Committee 
The Nomination Committee comprises Kevin Finn 
(Chairman) and Simon Rogers. The Nomination Committee 
met during the year to discuss the appointment of new 
members of the senior management team.
Corporate culture
The Board aims to lead by example and do what is in the 
best interests of the Company. It seeks to maintain the 
highest level of integrity in the conduct of the Group’s 
operations. An open culture is encouraged within the 
Group, with regular communication to staff regarding 
progress and staff feedback sought on a regular basis. 
Given the nature of the customers and markets within our 
systems business, a strict anti-bribery and corruption 
policy is operated to ensure that business dealings are 
carried out to the highest ethical standards.

SRT Marine Systems plc
Independent Auditor’s Report to the 
Members of SRT Marine Systems plc
Opinion
We have audited the financial statements of SRT Marine 
Systems plc (the ‘parent company’) and its subsidiaries 
(the ‘group’) for the 15 month period ended 30 June 2024 
which comprise the Consolidated Statement of Profit or 
Loss and Other Comprehensive Income, the Consolidated 
and Company Statements of Financial Position, the 
Consolidated and Company Statements of Cash Flows, 
the Consolidated and Company Statements of Changes in 
Equity, and the notes to the financial statements, including 
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 30 June 2024 and of the group’s loss for 
the period 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 as applied in 
accordance with the provisions of the Companies Act 
2006; and
•	
the financial statements have been prepared in 
accordance with the requirements of the Companies 
Act 2006.
Basis for opinion
We conducted our audit in accordance with International 
Standards on Auditing (UK) (ISAs (UK)) and applicable law. 
Our responsibilities 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 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. 
Our approach to the audit
Of the group’s ten reporting components, we subjected 
four to audits for group reporting purposes. Of the 
remainder, we performed analysis at a group level to re 
examine our assessment that there were no significant 
risks of material misstatements within these components, 
of which five were dormant and one is immaterial. 
The components within the scope of our work covered 
100% of group revenue, 100% of group loss before tax, 
and 100% of group net assets. 
The group audit team visited the premises where the 
parent and the two UK components are located. Video 
and telephone conference meetings were held with 
the component auditors in Ireland. At these visits and 
meetings, the group audit team discussed the component 
auditors’ risk assessments and planned audit approach. In 
addition to these planned visits and meetings, the group 
audit team sent detailed instructions to the component 
audit team and reviewed their audit findings. Once the audit 
work was completed, the findings reported to the group 
audit team were discussed in more detail, and any further 
work required by the group audit team was then performed 
by the component auditor. 
Key audit matters
Key audit matters are those matters that, in our 
professional judgment, 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) we identified, 
including those which had the greatest effect on: the 
overall audit strategy; the allocation of resources in the 
audit; and directing the efforts of the engagement team. 
These matters 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.

Description of risk
How the matter was addressed in the audit
Intangible 
fixed assets: 
Development 
costs – 
Group only
The group capitalises qualifying 
development costs as 
intangible fixed assets, which 
are material to the consolidated 
accounts. Over recent years, 
there has been a continued 
increase in the carrying value of 
the group’s development costs.
The audit risk is considered 
significant, given the stringent 
requirements that must be 
met to capitalise these costs 
and the judgment that can 
sometimes be needed in 
identifying which costs qualify 
for capitalisation. 
In addition, the value to the 
group of these costs, once 
capitalised, presents an area of 
audit risk, given the uncertainty 
and value of future sales, 
and the projected future life 
of the intangible asset and 
amortisation period assigned. 
There is also judgement 
as to the most appropriate 
amortisation period to apply to 
these assets.
The main procedures performed on the recognition and valuation 
assessments, including areas where we challenged management 
were as follows:
•	
Obtaining and agreeing the breakdown of intangible assets by 
ongoing/finalised projects to note 9 in the financial statements.
•	
Assessing the most significant costs capitalised per each project 
at period end against the stringent recognition criteria of IAS 38 
and corroborating the explanations received from management 
with information obtained elsewhere, such as corroborating sales 
levels on the projects for which amortisation is being charged to 
work performed on the respective sales area.
•	
Substantive testing of a sample of costs capitalised during the 
period by agreeing to supporting documents and assessing them 
against the recognition criteria of IAS 38.
•	
Reviewing the amortisation charged during the period, 
to ensure it has been calculated in accordance with the 
Group’s amortisation policy, and consideration of whether 
the amortisation period is appropriate for the specific costs 
capitalised.
•	
Reviewing management’s assessment of the value of the 
intangible assets against the impairment indicators of IAS 36.
•	
Reviewing and challenging the impairment review conducted to 
ensure the value of intangible assets not yet in use were more 
than covered by the recoverable amount. 
•	
Considering the appropriateness of the disclosures made in 
note 1 and note 9 in the financial statements in respect of these 
assets and the accompanying judgements.
Inventory 
valuation – 
Group only 
As product development 
continues the risk of 
obsolescence of inventories 
increases. Furthermore, the 
expected high levels of stock 
for current and anticipated 
contracts further increases the 
audit risk around valuation of 
stock items.
The main procedures performed on our review of inventory valuation, 
including areas where we challenged management, were as follows:
•	
Obtaining and agreeing detailed breakdowns of all inventory 
balances reported at the period end to note 13 in the financial 
statements.
•	
Substantive testing of a sample of inventory cost, agreeing the 
valuation of inventory to supporting purchase invoices.
•	
Substantive testing of a sample of inventory held to assess 
whether it is valued at the lower of cost and net realisable value, 
considering sales made post period end and sales agreements 
entered into which support the carrying value.
•	
Review slow moving items of stock and assess whether any 
provision should be made.
•	
Considering the appropriateness of the disclosures made in note 
1 and note 13 in the financial statements in respect of these 
assets and the accompanying judgements.

matter
Description of risk
How the matter was addressed in the audit
Revenues 
– for Group 
only
As shown within accounting 
policies note 1 on pages 29 and 
30, and note 2, the Group has a 
number of revenue streams in 
its subsidiary companies. Under 
auditing standards, there is a 
presumed significant fraud risk 
associated with the recognition 
of revenues, and we considered 
the risk to be most significant 
for systems contracts spanning 
the period end. We have noted 
a significant decrease in the 
level of revenues from the 
systems division in the current 
year. The systems contracts is 
where there can be judgement 
required as to what the 
performance obligations are 
and whether these have been 
met.
The main procedures performed on our review of the recognition of 
revenues, including areas where we challenged management, were as 
follows:
•	
Obtaining and agreeing detailed breakdowns of all revenue 
streams reported in the period into note 2 in the financial 
statements.
•	
Substantive testing of a sample of revenue transactions to 
invoices and receipt of monies from customer. 
•	
Substantive testing of a sample of revenue transactions around 
the period end to ensure revenues have been reported in the 
correct period.
•	
Reviewing the assessment made by management over the 
identification of performance obligations in the Group’s systems 
contracts, the revenue attributed to these performance 
obligations, and consideration of which performance obligations 
had been satisfied by the period end.
•	
Considering the appropriateness of the disclosures made in note 
1 and note 2 in the financial statements in respect of revenues.
Emphasis of Matter – recoverability of 
intangible assets, investment value, 
intercompany debtors, goodwill and inventory
We draw attention to note 1 in the financial statements 
concerning key sources of estimation uncertainty, and 
specifically the recoverability of £6.4m of intangible assets 
in the transceivers business; £634k of goodwill and £1.5m 
of inventory held on the Group statement of financial 
position; £35m of investment value and intercompany 
debtor of £5.3m on the statements of financial position of 
the Company.
As described in Note 1 – Critical accounting judgements 
and key sources of estimation uncertainty – the 
recoverability of investment value, intercompany debtors, 
goodwill and inventory are dependent on significant 
contracts being signed, delivered and cash collected, 
the timing of which is not certain. The recoverability of 
intangible assets are dependant on sales of the marine 
technology products being delivered and cash collected, 
the timing and actuality of which is not certain. The 
financial statements do not reflect any impairment that 
may be required if the above Group assets totalling, £8.5m 
or the above Company assets totalling £40.3m are not 
recoverable. Our opinion is not modified in respect of this 
matter.
Our application of materiality
The materiality for the group financial statements as 
a whole (“group FS materiality”) was set at £354k. This 
has been determined with reference to the benchmark 
of the group’s average revenues over the current 15 
month period and previous 2 years, given the significant 
fluctuations, which we consider to be one of the principal 
considerations for members of the company in assessing 
the group’s performance.  Group FS materiality represents 
2% of the group’s average revenues over the current 15 
month period and previous 2 years. The Group’s turnover 
is incurred in a non-linear manner with revenue recognised 
from systems projects not being incurred in regular 
intervals. Systems projects are normally installed over 
a 2-3 year period with the timing of revenue recognition 
being uncertain and often shifting dependent upon the 
specific operational aspects of each project. We therefore 
consider an averaged revenue approach to be appropriate 
for benchmarking materiality as this normalises revenue 
trends within the group on a rolling basis.
The materiality for the parent company financial 
statements as a whole (“parent FS materiality”) was set at 
£283k. This has been determined with reference to the 
benchmark of the parent company’s Gross assets as it 
exists only as a holding company for the group and carries 
on no external trade in its own right. Parent FS materiality 
represents 2% of the parent company’s gross assets as 
presented on the face of the parent company statement of

Annual Report and Financial Statements | 2024
SRT Marine Systems plc
financial position, capped at the performance materiality of 
the Group. 
Performance materiality for the group financial statements 
was set at £283k, being 80% of group FS materiality, for 
purposes of assessing the risks of material misstatement 
and determining the nature, timing and extent of further 
audit procedures.  We have set it at this amount to reduce 
to an appropriately low level the probability that the 
aggregate of uncorrected and undetected misstatements 
exceeds group FS materiality.  We judged this level to be 
appropriate based on our understanding of the group and 
its financial statements, as updated by our risk assessment 
procedures and our expectation regarding current period 
misstatements including considering experience from 
previous audits. It was set at 80% to reflect the previous 
experience of few audit adjustments, management’s 
cooperative attitude to adjusting differences if discovered 
and level of estimation and judgement in the financial 
statements.  
Performance materiality for the parent company financial 
statements was set at £184k , being 65% of parent FS 
materiality for purposes of assessing the risks of material 
misstatement and determining the nature, timing and 
extent of further audit procedures. We have set it at this 
amount due to the presence of multiple areas of complexity 
in the context of the parent entity that require higher 
levels of judgement. Further, we have set it at this amount 
to reduce to an appropriately low level the probability 
that the aggregate of uncorrected and undetected 
misstatements exceeds parent FS materiality and also the 
group materiality.  We judged this level to be appropriate 
based on our understanding of the company and its 
financial statements, as updated by our risk assessment 
procedures and our expectation regarding current period 
misstatements, including considering experience from 
previous audits. 
Conclusions relating to going concern
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. 
Our evaluation of the directors’ assessment of the group 
and parent company’s ability to continue to adopt the 
going concern basis of accounting included:
•	
challenging the assumptions used in the forecasts 
prepared by management for the financial years 
ending 2025 and 2026; 
•	
comparing the forecast results to those actually 
achieved in the 2025 financial period so far;
•	
agree contract sales forecasts into signed contract 
where available; 
•	
considering the Group’s funding position, cash 
requirements and access to loan facilities; and
•	
considering the sensitivity of the assumptions and 
reassessing headroom after sensitivity.
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 and 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.
Other information
The other information comprises the information included 
in the Annual Report and Financial Statements, 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 course of 
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 this gives rise to 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.

SRT Marine Systems plc
Opinions on other matters prescribed by the 
Companies Act 2006
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 period 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.
Matters on which we are required to report by 
exception
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.
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.
Responsibilities of directors
As explained more fully in the directors’ responsibilities 
statement set out on page 11, 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. 
The extent to which our procedures are capable of 
detecting irregularities, including fraud, is detailed 
below. Irregularities, including fraud, are instances of 
non-compliance with laws and regulations. We design 
procedures in line with our responsibilities, outlined above, 
to detect material misstatements in respect of irregularities, 
including fraud. 
We obtain a general understanding of the group’s legal 
and regulatory framework through enquiry of management 
in respect of their understanding of the relevant laws and 
regulations. We also drew on our existing understanding of 
the group’s industry and regulation.
We understand that the group complies with requirements 
of the framework through:
•	
The establishment of a testing department to ensure 
all Automatic Identification Systems (AIS) product 
approval requirements are met.
•	
Engaging external experts to ensure the Group remains 
in line with regulatory expectations and is aware of any 
updates to legislation.
•	
Given the management structure and reporting lines, 
any litigation or claims would come to the Directors’ 
attention and are considered at board meetings.
In the context of the audit, we considered those laws and 
regulations which determine the form and context of the 
financial statements, which are central to the group’s ability 
to conduct its business and where failure to comply could 
result in material penalties. We have identified the following 
laws and regulations as being of significance in the context 
of the group:

the preparation and presentation of the financial 
statements
•	
AIM rules and the UK Market Abuse Regulation
•	
Bribery Act 2010
•	
Health and safety regulations
We performed the following specific procedures to gain 
evidence about compliance with the specific laws and 
regulations defined above:
•	
Inspected the monthly board meeting minutes to 
ensure there are no reports of non-compliance
•	
Reviewed legal expense accounts to identify any 
potential legal issues which may indicate instances of 
non-compliance
•	
Inquired with lawyers as to the status of any potential 
or actual claims
•	
Reviewed the bribery policy to understand and 
consider how this supports the prevention of 
instances of bribery occurring within the group
The senior statutory auditor led a discussion with 
senior members of the engagement team regarding the 
susceptibility of the group’s financial statements to material 
misstatement, including how fraud might occur. The key 
areas identified as part of this discussion were:
•	
Manipulation of the financial statements through the 
posting of manual journals
•	
Valuation of stock and intangible assets where 
estimates are made by management
•	
Incorrect recognition of revenues, especially on the 
Group’s systems contracts
The procedures we carried out to gain evidence in the 
above areas included:
•	
Testing a sample of manual journals back to supporting 
documentation
•	
Testing a sample of capitalised development costs 
back to supporting documentation and confirming 
that they are capital in nature (see Key Audit Matter 
regarding Intangible Assets for further detail)
•	
Testing the cost and net realisable value of a sample of 
stock lines to ensure that they are valued correctly (see 
Key Audit Matter regarding inventory for further detail)
•	
Testing the basis on which revenues have been 
reported on the Group’s systems contracts, by 
reference to the requirements of IFRS 15
Overall, the senior statutory auditor was satisfied that 
the engagement team collectively had the appropriate 
competence and capabilities to identify or recognise 
irregularities. In particular, both the senior statutory auditor 
and the audit manager have a number of years’ experience 
in dealing with companies in the technology development 
sector and those with cross-border activities, and also with 
companies listed on the AIM market of the London Stock 
Exchange.
A further description of our responsibilities is 
available on the FRC’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 parent 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 parent 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 parent company 
and the parent company’s members as a body, for our audit 
work, for this report, or for the opinions we have formed.

Annual Report and Financial Statements | 2024
SRT Marine Systems plc
Notes to the Accounts for the 
15-Month Period Ended 30 June 2024
1. Accounting policies
SRT Marine Systems plc is a public limited Company, 
limited by shares, incorporated in England and Wales. It 
is listed on the AIM. The address of the registered office 
is Wireless House, Westfield Industrial Estate, Midsomer 
Norton, Bath BA3 4BS. The nature of the Group’s 
operations and its principal activities are noted in the 
Chairman’s Statement and Strategic Report. The principal 
accounting policies are summarised below. They have all 
been applied consistently throughout the period covered 
by these financial statements.
Basis of preparation
The financial statements have been prepared in 
accordance with UK-adopted international accounting 
standards. The financial statements have been prepared 
under the historical cost convention.
Basis of consolidation
The Group financial statements incorporate the financial 
statements of the Company and entities controlled by the 
Company prepared to 30 June in the current period. During 
the period, the Company changed its year end from 31 
March to 30 June. An investor controls an investee if the 
investee has all of the following: power over the investee; 
exposure or rights, to variable returns from its involvement 
with the investee; and the ability to use its power over the 
investee to affect the amount of the investor’s returns. All 
intra-Group transactions and balances and any unrealised 
gains and losses arising from intra-Group transactions 
are eliminated in preparing the consolidated financial 
statements.
Going concern 
The Group’s business activities, together with the key 
factors likely to affect its future development, profitability, 
cash flows, liquidity position, borrowing facilities and 
financial position are outlined within the Chairman’s 
Statement, Strategic Report and the financial statements. 
The directors have prepared the financial statements on 
the going concern basis, which assumes that the systems 
business will generate sufficient future recoverable income.
The level of future income to be generated is dependent 
on the timing of the awarding and execution of contracts 
and cash receipts from the Group’s systems business. 
Two significant systems contracts have now been 
awarded to the Group and these are expected to generate 
material cash receipts in the next 12 months although the 
Directors recognise that it is very difficult to predict the 
exact timing of these cash receipts. In order to mitigate 
the potential impact on cash flows, the Group completed 
financing exercises during the period and is in the process 
of finalising an additional equity raise subsequent to the 
year end, with shareholder approval being sought in early 
December. The directors do not consider there to be any 
significant uncertainty in the approval being obtained.
The Directors believe they have a reasonable basis to 
conclude that the Group and Company have adequate 
resources to continue in operational existence for the 
foreseeable future and for this reason, the directors 
continue to adopt the going concern basis in preparing 
the financial statements. The financial statements do not 
include any adjustments that would result if the company 
was unable to continue as a going concern. 
Business combinations and goodwill
Business combinations are accounted for using the 
acquisition method as at the acquisition date, which is the 
date on which control is transferred to the Group. 
The consideration transferred for the acquisition of a 
subsidiary is the fair values of the assets transferred, the 
liabilities incurred and the equity interests issued by the 
Group. The consideration transferred includes the fair 
value of any asset or liability resulting from a contingent 
consideration arrangement. Identifiable assets acquired 
and liabilities and contingent liabilities assumed in the 
business combination are measured initially at their fair 
values at the acquisition date. 
Critical accounting judgements and key 
sources of estimation uncertainty 
The preparation of financial statements in conformity 
with generally accepted accounting practice requires 
management to make estimates and judgements that 
affect the reported amounts of assets and liabilities as 
well as the disclosure of contingent assets and liabilities at 
the year-end date and the reported amounts of revenues 
and expenses during the year. Estimates and judgements 

www.srt-marine.com
30 June 2024
28
Annual Report and Financial Statements | 2024
SRT Marine Systems plc
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.
Judgements
•	
Development costs capitalised as intangible assets
Management exercises judgement in determining 
whether the costs can be capitalised, and this is 
done by reference to a number of criteria as set out 
in these accounting policies. During the 15 month 
period ended 30 June 2024, the Group has capitalised 
development costs of £5,732,755 (Year ended 31 
March 2023: £4,795,292).
•	
Determination of performance obligations 
For the purposes of recognising revenue, management 
has exercised judgement in considering the 
performance obligations in its long-term contracts 
to be building a monitoring system, delivering and 
installing transceivers and providing services such as 
data, training, warranty and support. 
•	
Allocation of transaction price
The allocation of the total price to performance 
obligations is done, where possible, on the basis of 
relative stand-alone selling prices, which may need 
to be estimated as some performance obligations 
are never, in practice, sold on their own. Management 
exercises judgement to determine the best approach 
for allocating the transaction price to performance 
obligations where relative stand-alone prices are not 
readily available as some of the contracts are highly 
bespoke. The residual method of allocation of the 
transaction price is used when stand-alone prices are 
not available.
•	
Revenue recognition method for performance 
obligations where satisfaction is over time
The Group uses either output methods or input 
methods to measure the progress towards completion 
of a performance obligation satisfied over time, 
depending on which method is considered to depict 
the entity’s performance. Output methods recognise 
revenue on the basis of direct measurement of the 
value to the customer of the goods or services 
transferred to date relative to the remaining goods 
or services promised under the contract. The output 
method used by the Group is based on milestones 
reached. Most contracts which use the output method 
are installed over a 2-3 year period. Input methods 
recognise revenue on the basis of the entity’s 
efforts or inputs to the satisfaction of a performance 
obligation relative to the total expected inputs to 
the satisfaction of that performance obligation. The 
input method used by the Group is based on costs 
incurred to date relative to total expected costs, which 
requires significant judgement. Contracts can be highly 
bespoke and hence historical cost information is not 
always useful in estimating future costs. The Group’s 
policies for the recognition of revenue and profit are 
set out in the revenue recognition policy on page 30.
•	
Determination of the lease term
Rental contracts are typically made for fixed periods 
but may have extension options. In these cases, 
significant judgement is required to ascertain the 
correct lease term. When assessing whether the Group 
is reasonably certain to exercise the option to extend 
the lease, the directors consider all relevant facts and 
circumstances (both monetary and non- monetary) 
that create an economic incentive for them to exercise 
or not exercise that option. They also include any 
expected changes in facts and circumstances from 
the commencement date until the exercise date of that 
option.
•	
Amortisation of development costs
Management consider the amortisation period of 
each development cost asset based on the revenue 
generating life of each asset, currently considered to 
be five years. Where an asset is not ready for use at 
the year end and therefore has not been amortised, 
management perform impairment reviews based upon 
anticipated future cash flows as detailed in the going 
concern section of this note.
Key sources of estimation uncertainty
•	
Impairment of property, plant and equipment
Management tests property, plant and equipment 
for impairment if and when indicators of impairment 
arise. Where such an indication exists, management 
estimates the fair value less costs to sell of the assets 
based on the net present value of future cash flows. 
The directors have considered whether there are any 
indicators of impairment to the carrying amount of 
property, plant and equipment of £1,131,528 (2023: 
£1,256,223). The unpredictability of cash flows in the 
Group’s system business has resulted in the existence 
of an impairment indicator which has been considered 
by the directors. Whilst recognising the challenges in 
forecasting these cash flows, the directors consider 
that they have used a reasonable basis to forecast the 
timing of these cash receipts.
•	
Impairment of intangible assets
Management tests intangible assets for impairment if 
and when indicators of impairment arise. Where such 
an indication exists, management estimates the fair 
value less costs to sell of the assets based on the 
net present value of future cash flows. The directors 
have considered whether there are any indicators of 

30 June 2024
29
www.srt-marine.com
Annual Report and Financial Statements | 2024
SRT Marine Systems plc
impairment to the carrying amount of intangible assets 
of £14,170,410 (2023: £11,756,717) including goodwill 
of £633,645 (2023: £633,645). The variability of trading 
conditions in the Group’s system business has resulted 
in the existence of an impairment indicator which has 
been considered by the directors. The Group has 
signed some significant contracts, a significant portion 
of which are expected to be invoiced in the next 3 
accounting periods. The key sensitivity to the cash 
flows associated with the contracts is the timing and 
collection of cash, based on achieving milestones. A 
delay in excess of 12 months in the invoicing of these 
milestones could lead to a potential impairment of the 
intangible assets. Included in the above are £6.4m of 
pre-revenue products in the transceivers business 
where, as a result, these uncertainties are heightened. 
The recoverability of these assets is dependent on 
the sales of the marine technology products being 
delivered and cash collected, the timing and actuality 
is not certain. Whilst recognising the challenges in 
forecasting these cash flows, the directors consider 
that they have used a reasonable basis to forecast the 
timing of these cash receipts.
•	
Valuation of inventory
Inventory is held at the lower of cost and net realisable 
value and is held for the Group’s transceiver business 
£2,893,793 and its systems business £5,157,106. 
If transceiver inventory is held for a long period of 
time or relates to a product line that is superseded, 
then the net realisable value is brought into question. 
Management perform a review of any such inventory 
and provides accordingly thereby seeking to 
ensure that the value at which inventories are held 
is appropriate. Systems inventory is reviewed for 
provision based on the assessment of sales patterns 
which can be unpredictable in their timing and hence 
difficult to forecast. The total provision at 30 June 
2024 amounted to £967,889 (2023: £764,271).
•	
Recoverability of inventory
Management recorded inventory at the lower of cost 
and net realisable value, and in making this assessment 
has given particular regard to inventory with a value 
of £1,534,501 (2023: £192,182) that is held for 
anticipated contracts, against which no provision is 
maintained. The realisation of this value is dependent 
on significant contracts being signed, delivered and 
cash collected. Whilst the directors are confident that 
the contracts will be secured to realise this value, there 
remains uncertainty in this regard.
•	
Investments 
The company accounts include an investment 
in subsidiaries balance of £35,024,253 (2023: 
£20,924,253) and inter-company receivable balances 
of £5,258,783 (2023: £973,983). Management tests 
investments for impairment if and when indicators of 
impairment arise. The unpredictability of cash flows 
in the Group’s system business has resulted in the 
existence of an impairment indicator which has been 
considered by the directors. The recoverability of these 
assets is dependent on significant contracts being 
signed, delivered and cash collected with the projects 
arm of the Group, the timing of which is not certain. 
The sensitivities to these cash flows are considered in 
the impairment of intangible assets uncertainty. Whilst 
recognising the challenges in forecasting these cash 
flows, the directors consider that they have used a 
reasonable basis to forecast the timing of these cash 
receipts. When undertaking this assessment, the 
directors have adopted a pre-tax discount rate of 20% 
and a terminal growth rate of 2%.
Research and development
Research expenditure is written off to profit or loss in the 
year in which it is incurred. Development expenditure is 
capitalised and amortised over the period during which the 
Company is expected to benefit, currently considered to 
be five years. This cost is included as part of administrative 
expenses within profit or loss.
Development expenditure capitalised represents time 
spent by Company employees, sub-contractor costs, and 
any other directly attributable costs incurred in creating the 
asset for the purposes intended by management, valued 
at cost. In recognising such development costs as assets 
consideration is given to each of the following:
•	
The technological feasibility of completing the asset so 
that it may be used or sold 
•	
The intention and ability to use or sell the asset
•	
How the asset will generate future probable economic 
benefits, for example by demonstrating that there is a 
market for the asset’s output
•	
Availability of adequate technical, financial and other 
resources to complete the development and to use 
the asset
•	
The ability to measure reliably the expenditure on the 
asset during its development.
Once management is satisfied that the above criteria are 
met the development costs are carried as assets. The 
amortisation periods of each of the assets is five years, 
as this is considered to be the revenue generating life 
of each asset. This period is subject to annual review by 
management. The AIS technology assets have between 
3 and 60 months of amortisation remaining.

Revenue recognition 
Revenue is recognised in accordance with the transfer 
of promised goods or services to customers (i.e. when 
the customer gains control of the good/service) and is 
measured as the consideration which the Group expects 
to be entitled to in exchange for those goods or services. 
Consideration is typically fixed on the agreement of a 
contract. Payment terms are agreed on a contract-by-
contract basis. 
Contracts include promises to transfer goods and/or 
services to a customer (i.e. “performance obligations”) 
which are typically indistinct and hence are accounted for 
together in a single performance obligation. Where multiple 
performance obligations exist within one contract, the 
transaction price is allocated between each performance 
obligation on the basis of past experience, with reference 
to stand-alone selling prices of each component, and 
where appropriate by using the residual method approach.
A good or service is distinct if the customer can benefit 
from the good or service on its own or together with other 
resources that are readily available to the customer and 
the entity’s promise to transfer the good or service to the 
customer is separately identifiable from other promises in 
the contract.
The group recognises revenue when (or as) it satisfies a 
performance obligation by transferring a promised good or 
service to a customer. A performance obligation is satisfied 
over time when the vendor’s performance creates an 
asset under the control of the customer and the customer 
has an obligation to pay the vendor for performance to 
date, or when the customer simultaneously receives and 
consumes the benefits from the performance obligation. 
The group recognises revenue from the sale of support 
services, maintenance and training over the time period to 
which the services provided relate, as this is considered 
the best indicator of when the customer receives and 
consumes the benefit of the service. 
The group recognises revenue from the sale of maritime 
system solutions over the time as the monitoring system 
and transceivers are installed on the customer’s territory 
and therefore the asset is deemed under the customer’s 
control. The Group uses either output methods or input 
methods to measure the progress towards completion of a 
performance obligation satisfied over time, depending on 
which method is considered to faithfully depict the entity’s 
performance.
Output methods recognise revenue on the basis of direct 
measurement of the value to the customer of the goods 
or services transferred to date relative to the remaining 
goods or services promised under the contract. The 
output method used by the Group companies is based on 
milestones reached. Input methods recognise revenue on 
the basis of the entity’s efforts or inputs to the satisfaction 
of a performance obligation relative to the total expected 
inputs to the satisfaction of that performance obligation. 
The input method used by the Group is based on costs 
incurred to date. 
If revenue is recognised over a period of time, the Group 
presents as a contract asset the gross amount due from 
customers for contract work for all contracts in progress 
for which costs incurred plus recognised profits (less 
recognised losses) exceeds progress billings. Progress 
billings not yet paid by customers and retentions are 
included within ‘trade and other receivables’. The Group 
presents as a liability the gross amount due to customers 
for contract work for all contracts in progress for which 
progress billings exceed costs incurred plus recognised 
profits (less recognised losses). Contract asset and liability 
balances fluctuate due to the timing and mix of contracts 
held across the Group.
The group recognises revenue from the sale of goods and 
licenses at the point in time that goods are transferred to 
a customer, which is the point in time that the customer 
gains control of the goods. This is due to the nature 
of goods being fairly standardised and hence specific 
contract accounting does not apply.
Contracts are deemed to be complete, and hence 
performance obligations fully satisfied, post customer 
acceptance of the goods. Amounts disclosed as current 
deferred income reflect revenue that will be recognised on 
performance obligations that will be satisfied within a year. 
The aggregate amount of the transaction price allocated 
to the performance obligations that are unsatisfied, or 
partially unsatisfied, as of the end of the reporting period 
is £ nil (2023: £3,829,403). This amount will be recognised 
over the remaining life of the contract.
Property, plant and equipment
All property, plant and equipment are valued at net book 
value, being the cost less accumulated depreciation 
and any impairment losses where there is an impairment 
recognised. Depreciation is provided on cost in equal 
annual instalments over the estimated useful lives of the 
assets concerned. Annual lives of 3-4 years are used for 
owned plant and equipment. All right of use assets are 
depreciated in equal instalments over the remaining term 
of the lease.

Taxation 
Where an income tax credit arises, this represents the sum 
of the tax currently receivable and deferred tax. Current tax 
is based on taxable profits for the year using tax rates and 
laws that have been enacted or substantively enacted by 
the statement of financial position date. 
Deferred tax is provided for on a full provision basis on all 
temporary differences, which have arisen but not reversed 
at the statement of financial position date. Temporary 
differences represent the accumulated differences 
between the carrying amounts of assets and liabilities in 
the financial statements and the corresponding tax bases 
used in the computation of taxable profit. Deferred tax is 
calculated at the tax rates that are expected to apply when 
the related deferred tax balance is settled. Deferred tax is 
charged or credited to profit or loss, except when it relates 
to items charged or credited directly to equity in which 
case the deferred tax is also dealt with in equity. Deferred 
tax assets are recognised to the extent that it is probable 
that there will be suitable taxable profits from which the 
future reversal of the underlying temporary differences can 
be deducted.
Pension costs
Contributions to defined contribution schemes are 
recognised on an accrual basis in accordance with the 
rules of the scheme.
Foreign currencies
Transactions denominated in a foreign currency are 
translated into sterling at the rate of exchange ruling at 
the date of the transaction. At the statement of financial 
position date, monetary assets and liabilities denominated 
in foreign currency are translated at the rate ruling at that 
date. All exchange differences are dealt with in profit or 
loss.
Inventories
Inventories and work in progress are stated at the lower 
of cost and net realisable value. Cost comprises direct 
materials and other subcontracted manufacturing costs. 
The costs of finished products are expensed to profit 
or loss to match against the corresponding revenues 
from those products. Net realisable value represents 
the estimated selling price less all estimated costs of 
completion and costs to be incurred in marketing, selling 
and distribution. Provision is made against slow moving 
and obsolete inventories to ensure the value at which 
inventories are held in the statement of financial position is 
reflective of anticipated future sales patterns.
Share based payments
The Group operates an equity settled share-based 
compensation plan whereby the Company grants share 
options to employees of all Group companies. The fair 
values of the options granted under this plan are calculated 
using an appropriate valuation model which takes into 
account assumptions about future events and market 
conditions. Further details are provided in note 19.
The cost of equity-settled transactions is recognised, 
together with a corresponding increase in equity, over 
the period in which the performance and/or service 
condition are fulfilled, ending on the date on which the 
relevant employees become fully entitled to the award. 
The cumulative expense recognised for equity-settled 
transactions at each reporting date, until the vesting date, 
reflects the extent to which the vesting period has expired 
and the Directors’ best estimate of the number of equity 
instruments that will ultimately vest.
In making this judgement consideration must be made 
as to the likely number of shares that will vest, and the fair 
value of each award granted. The fair value is determined 
using a valuation model, which is dependent on further 
estimates, including the Group’s future dividend policy, 
employee turnover, the timing with which options will be 
exercised and the future volatility in the price of the Group’s 
shares. Such assumptions are based on publicly available 
information and reflect market expectations. 
Financial instruments 
Financial assets and financial liabilities are recognised 
in the statement of financial position when the Group 
becomes a party to the contractual provisions of the 
instrument.
Trade receivables and contract assets
Trade receivables are held in order to collect the 
contractual cash flows and are initially measured at the 
transaction price as defined in IFRS 15, as the contracts of 
the Group do not contain significant financing components. 
Impairment losses are recognised based on 12 month 
expected credit losses in profit or loss. The Group does 
business and extends credit based on an evaluation of the 
customers’ financial condition, generally without requiring 
collateral. Exposure to losses on receivables is expected 
to vary by customer due to the financial condition of 
each customer. The Group monitors exposure to credit 
losses and maintains allowances for anticipated losses 
considered necessary under the circumstances. As of 
30 June 2024, there was a provision of £705,562 held as 
an allowance for doubtful accounts, see note 14 for 
further detail.

Annual Report and Financial Statements | 2024
SRT Marine Systems plc
Other receivables are held in order to collect the 
contractual cash flows and accordingly are measured at 
initial recognition at fair value, which ordinarily equates 
to cost and are subsequently measured at cost less 
impairment due to their short-term nature. A provision for 
impairment is established based on 12 month expected 
credit losses unless there has been a significant increase 
in credit risk when lifetime expected credit losses are 
recognised. The amount of any provision is recognised in 
profit or loss.
Cash and cash equivalents
Cash and cash equivalents comprise cash held by the 
Group and short term bond deposits with an original 
maturity of three months or less.
Borrowings
Interest-bearing loans and overdrafts are recorded initially 
when the proceeds are received. Finance charges are 
accounted for at amortised cost using the effective interest 
rate method.
Trade payables
Trade payables are non-interest bearing and are initially 
measured at their fair value and subsequently at their 
amortised cost.
Leases
Right of use assets and lease liabilities are recognised and 
measured in accordance with IFRS 16.
A right of use asset and a lease liability has been 
recognised for all leases except leases of low value assets, 
which are considered to be those with a fair value below 
£5,000, and those with a duration of 12 months or less. 
The right-of-use asset has been measured at cost, which 
is made up of the initial measurement of the lease liability, 
any initial direct costs incurred by the Group, an estimate of 
any costs to dismantle and remove the asset at the end of 
the lease, and any lease payments made in advance of the 
lease commencement date.
The Group will depreciate the right-of-use assets on a 
straight-line basis from the lease commencement date to 
the earlier of the end of the useful life of the right-of-use 
asset or the end of the lease term. Where impairment 
indicators exist, the right of use asset will be assessed for 
impairment.
The lease liabilities are measured at the present value of 
the lease payments due to the lessor over the lease term, 
discounted using the interest rate implicit in the lease if 
that rate is readily available or the Group’s incremental 
borrowing rate.
After initial measurement, any payments made will reduce 
the liability and the interest accrued will increase it. Any 
reassessment or modification will lead to a remeasurement 
of the liability. In such case, the corresponding adjustment 
will be reflected in the right-of-use asset, or profit or loss if 
the right-of-use asset is already reduced to zero.
On the statement of financial position, right-of-use assets 
have been included in property, plant and equipment.
Changes in accounting policies and 
disclosures
New and amended standards adopted by the Group
The new and amended standards and interpretations 
applicable to the group for the first time this year have not 
had a material impact on the disclosure, or the amounts 
reported in the financial statements.
New standards and interpretations 
not yet adopted 
During the next financial year, there will be amendments 
to IAS 1 Presentation of Financial Statements and IAS 8 
Accounting Policies, Changes in Accounting Estimates 
and Errors in relation to the definition of material. 
The amendments are likely to require some reduced 
disclosures in the financial statements.
The directors have considered the other new and amended 
standards and interpretations effect next year and are 
satisfied that these will not have a material impact on the 
Group.

2. Revenue and segment information 
Business and geographical segments 
The directors have given due consideration to the 
requirements of IFRS 8 and the components of the Group 
which management use to make decisions about operating 
matters and internal reports that are regularly reviewed by 
the chief operating decision maker, which is considered to 
be the board of directors. 
As in previous years, it has been concluded by 
management and the Board that the organisation is 
structured as a single business segment, the Marine 
technology business. The Marine technology business 
is the segment which provides solutions to solve the 
problem of maritime domain awareness, both products and 
systems and which reflects the results presented in the 
primary statements. Individual contracts are specifically 
considered by management and the board if their 
magnitude is considered significantly large to warrant such 
consideration.
From a geographical perspective, the Group earns revenue 
from a number of countries as set out below:

Included within revenue is one customer (2023: three) with 
an amount exceeding 10% of the Group’s total revenue. 
In the current period, the largest customer was from the 
UK, with sales amounting to £2,492,475. (2023 – the 
largest customer was from the Middle East with sales of 
£12,401,520, the second largest from the Philippines with 
sales of £5,560,413 and the third largest from Belgium 
with sales of £4,144,748). All sales were within the Marine 
technology business segment. 
Revenue from the Group’s customers in the Middle East 
and the Philippines is recognised over time whilst all other 
revenue is recognised at a point in time.

Options expiring August 2026
Those options granted to S Tucker, N Peniket and R Hurd 
at an exercise price of 0.1p and an expiry date of August 
2026 vest in three equal tranches dependent on the 
Company’s share price. The first tranche vests when the 
share price has exceeded 50p. This occurred during the 
year ended 31 March 2017 and so the first tranche has 
vested and is exercisable. The second and third tranches 
vest on the same basis but with thresholds of 75p and 
£1.25 which have not yet been met and as such are not 
exercisable.
Options expiring May 2030
Those options granted to N Peniket, R Hurd and JF Bonnin 
at an exercise price of 0.1p and an expiry date of May 
2030 vest based on four equal tranches dependant on the 
Company’s share price exceeding 75p, £1.25, £1.50 and 
£2.00. Irrespective of these share price targets, 10% vest 
after 2 years and a further 25% after 5 years from the date 
of grant. Furthermore, options were granted to K Finn and 
S Barrell with the same vesting criteria but with an exercise 
price of 32.5p. As at period end, the 2 year vesting criteria 
has been met and therefore 10% of those options have 
vested and are exercisable. No other vesting criteria has 
been met and as such the remaining 90% of those options 
have not yet vested and are not exercisable. 
Options expiring May 2032
During the previous year, 2,500,000 options were granted 
to S Tucker at an exercise price of 0.1p and an expiry date 
of May 2032. These options vest in five equal tranches 
dependent on the Company’s share price exceeding £1.25, 
£1.50, £2.00, £2.50 and £3.00. The vesting criteria have not 
been met and as such those options have not yet vested 
and are not exercisable.
An insurance premium of £28,021 (2023: £28,000) was 
paid in respect of directors’ and officers’ liability. Retirement 
benefits are accruing to two directors (2023: two) under 
the money purchase pension scheme.

The current year rate of 25% arises from changes to legislation enacted during 2021. The main rate 
of corporation tax in the UK increased from 19% to 25% with effect from 1 April 2023. In June 2023 
Finance Act (No.2) 2023 was substantively enacted in the UK, introducing a global minimum effective 
tax rate of 15% in line with the OECD Pillar Two model rules. The legislation implements a domestic 
top-up tax and a multinational top-up tax, effective for periods starting on or after 31 December 2023. 
The new rules are not expected to have a material impact on the Company’s operations or results.

8. Company loss for the financial year
The Company has taken advantage of the exemption under Section 408 of the Companies Act 2006 not to publish 
its individual income statement. The loss for the 15 month period ended 30 June 2024, dealt with in the financial 
statements of the Company, was £2,476,590 (Year ended March 31 2023: loss £1,699,238). The Company made 
no gains or losses which would be reported in other comprehensive income in the 15 month period ended 30 June 
2024 and year ended 31 March 2023 and therefore the Company has not published its individual Statement of 
Comprehensive Income.

Goodwill acquired in a business combination is allocated, at 
acquisition, to the Marine Cash generating unit (CGU) which 
is the sole CGU.
The recoverable amount of the goodwill has been 
determined based on a value in use calculation. That 
calculation uses cash flow projections covering a five-year 
period, a terminal growth rate of 2% and a pre-tax discount 
rate of 20% that reflect current market assessments of the 
time value of money and the risks specific to the market in 
which the Marine CGU operates.
The main assumption in the cash flow projections is the 
budgeted sales which have been determined using in-
house estimates based upon detailed discussions with 
the Group’s customers and risk discounts applied where 
necessary. Sensitivities to these cash flows are considered 
in note 1.
Management has concluded, based on its forecasts and 
the net present value of its forecast future cash flows, that 
there is no recognised impairment. None of the goodwill is 
expected to be tax deductible. 
Development costs in respect of assets not in use are 
subject to an impairment review using the same cash flow 
assumptions as above.

As at 30 June 2024, the Group had a balance of £949,115 (2023: £949,115) 
which was held in a restricted bank account by the Group’s bankers. This 
balance is being held as security against any possible liability arising from a 
performance bond issued by the bank to the Group’s customer on one of its 
systems projects. The Group does not expect any liabilities to arise on this 
project and thus the cash to be returned on completion in the year ended

As at 30 June 2024 trade receivables and contract asset balances of £372,801 
(2023: £380,070) were past due but not impaired. The ageing analysis of these trade 
receivables is set out below. The Company applies the IFRS 9 simplified approach 
to measuring expected credit losses using a lifetime expected credit loss for trade 
receivables. To measure expected credit losses on a collective basis, trade receivables 
are grouped based on the percentage of sales made to the customer group and each 
is allocated a similar credit risk. No ECL provision has been raised as it has not been 
deemed material.

The group has long-term property leases with a total value of £641,916 and with maturity 
dates varying between 1 and 5 years. Furthermore, it has leases on office equipment with 
a value of £95,185 with maturity dates varying between less than one year and 2 years. 
The company has long-term property leases with a total value of £230,049 and with a 
maturity date of 5 years. Furthermore, it has leases on office equipment with a value of 
£94,773 with maturity dates varying between less than 1 year and 2 years.
The Company holds leases for five buildings and for office equipment. These leases are 
reflected in the statement of financial position as a right-of-use asset and a lease liability. 
The company classifies its right of use assets in a consistent manner to its property, plant 
and equipment. The early termination clauses within all but one lease have expired. The 
remaining lease with an early termination clause is not anticipated to be exercised.
Each lease generally imposes a restriction that, unless there is a contractual right for the 
Company to sublet the asset to another party, the right-of-use asset can only be used by 
the Company. Leases may only be cancelled by incurring a substantive termination fee. 
The Company must keep the buildings in a good state of repair and return the properties 
in their original condition at the end of the lease. Further, the Company must insure right-
of-use assets and incur maintenance fees on such items in accordance with the lease 
contracts.
The interest charged on leases for the 15-month period ended 30 June 2024 has been 
disclosed in note 5. The depreciation charged on leases for the 15-month period ended

19. Share based payment 
The Company operates an Enterprise Management Incentive share option scheme and a 
Non-Enterprise Management Incentive scheme for directors and employees. The general 
terms of the schemes are that awards are made once an employee has completed a 
minimum of six months’ service with the Group. The awards made to employees are at 
the discretion of the Management Team and those to the directors at the discretion of the 
Remuneration Committee.
The options are expected to vest over a period of up to four years and the maximum 
exercise period for the options is ten years from the date of grant. Upon vesting the options 
are equity settled. Details of the share options outstanding during the year and previous 
year are as follows:

The value of the options granted during the period have been measured by using the Black 
Scholes pricing model as adjusted where applicable for market-based performance criteria. 
The inputs into the Black Scholes model included expected lives of up to 4 years as well as 
the relevant share price, exercise price, volatility and risk-free rate at the date of grant. The 
options granted during the year had exercise prices of 0.1p and a share price on the date of 
issue ranging from 42p–51.5p.
Expected volatility was determined by referencing volatility data received and using 
historical data for similar sized companies over the previous five years and amounted to 
approximately 60% for the grants made during the period. Risk free rates were determined 
using government bonds and amounted to between 3.4% and 4.6%. The expected dividend 
yield was 0%.

23. Basic and diluted (loss) / earnings per share
The basic loss per share has been calculated on the loss after taxation of £13,653,819 (2023: profit 
£69,520) divided by the weighted number of ordinary shares in issue of 202,114,658 (2023: 180,961,021). 
During the current period, the Group incurred a loss after taxation and therefore there is no dilution of the 
impact of the share options granted.
During the previous year the calculation of diluted earnings per share has been calculated on profit after 
taxation of £69,520. It assumes conversion of all potentially dilutive ordinary shares, all of which arise 
from share options. A calculation is performed to determine the number of shares that could have been 
acquired at fair value, based upon the monetary value of subscription rights to outstanding share options. 
The number of dilutive shares under option was 1,958,724 and the weighted average number of ordinary 
shares for the purposes of dilutive earnings per share was 182,919,745.

24. Financial instruments
The Group and Company’s financial instruments comprise 
cash and cash equivalents, borrowings, lease liabilities 
and items such as trade payables and trade receivables 
which arise directly from its operations. The main purpose 
of these financial instruments is to provide finance for the 
Group and Company’s operations.
The Group and Company’s operations expose it to a variety 
of financial risks including credit risk, interest rate risk and 
foreign currency exchange rate risk. Given the size of the 
Group and Company, the directors have not delegated 
the responsibility of monitoring financial risk management 
to a sub-committee of the board. The policies set by the 
board of directors are implemented by the Group’s finance 
department. 
Credit risk
The Group’s credit risk is primarily attributable to its 
trade receivables and accrued income balances. The 
Company had no trade receivables at 30 June 2024 (2023: 
£nil). The Group has implemented policies that require 
appropriate credit checks on potential customers before 
sales are made. The amount of exposure to any individual 
counterparty is subject to a limit, which is reassessed 
annually by each subsidiary’s management team. The 
carrying amount of financial assets represents the 
maximum credit exposure. 
The maximum credit exposure as at the reporting date was:

At 30 June 2024, The Company has cash and cash 
equivalents of £187,670 (31 March 2023: £26,135) and no 
trade receivables.
Interest rate risk
The Group and Company have interest bearing assets and 
liabilities which comprise of cash and cash equivalents and 
short and medium term loans (note 16) and lease liabilities 
(note 17) which earn or incur interest at a fixed rate. The 
Group and Company have not entered into any derivative 
transactions during the period under review.
The Group and Company’s cash and cash equivalents 
earned interest at a variable rate totalling £44,073 (2023: 
£351) during the period. Interest payable on the short 
and medium term loans at a variable rate amounted to 
£1,208,402 (2023: £742,660) for the Group and Company 
together with interest on lease liabilities of £44,688 (2023: 
£38,887). 
Liquidity risk
The Group maintains a mixture of long-term and short-term 
debt finance that is designed to ensure it has sufficient 
available funds for operations and future expansion 
opportunities. The Group monitors its levels of working 
capital to ensure that is can meet its debt repayments as 
they fall due. Debt maturity is disclosed in note 16. Trade 
and other payables are due on 30 days as standard.
Foreign currency exchange rate risk
The Group is exposed to foreign currency exchange rate 
risk as a result of trade payables and trade receivables 
which will be settled in US Dollars, Euros, Saudi Riyal and 
Philippine Peso. The Company had no material exposure 
to foreign exchange risk. During the year the Group did 
not enter into any arrangements to hedge this risk, as the 
directors did not consider the exposure to be significant. 
The Group will review this policy as appropriate in the 
future. 	
The Group’s currency exposure comprises monetary 
assets and liabilities that are denoted in currencies 
other than sterling, principally those denominated in 
US Dollars, Euro, Saudi Riyals and Philippine Peso. Such 
transactions give rise to net currency gains and losses 
recognised in profit or loss. At the period end this exposure 
comprised £1,099,438 (2023: £1,843,107) of assets 
denominated in US Dollars, £320,153 (2023: £415,529) 
of assets denominated in Euros, and £60,018 (2023: 
£1,253,209) of assets denominated in Philippine Peso 
and £737,251(2023: £3,451,384) of assets denominated 
in Saudi Riyal. Furthermore, the Group at period end had 
£970,816 (2023: £975,524) of liabilities denominated in US 
Dollars, £46,729 (2023: £78,976) of liabilities denominated 
in Euros, £43,459 (2023: £75,095) of liabilities denominated 
in Philippine Peso and £230,422 (2023: £3,804,665) of 
liabilities denominated in Saudi Riyal.

The Group’s objectives when managing capital are to 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 to shareholders. The Group 
defines capital as being share capital plus reserves which 
amounted to £12,053,172 at 30 June 2024 (31 March 
2023: £10,307,619). The Board of Directors monitors the 
level of capital as compared to the Group’s long-term 
debt commitments and adjusts the ratio of debt to capital 
as is determined to be necessary, by issuing new shares, 
reducing or increasing debt paying dividends. The Group is 
not subject to any externally imposed capital requirements, 
except as disclosed in note 16.
26. Financial commitments

27. Subsequent events
On 28th October, an existing shareholder, Ocean Infinity 
provided a $21.4m guarantee to enable the Group to 
issue a performance bond of a similar value in respect of a 
project contract worth $213m which was signed on 30th 
October 2024. This guarantee was initially provided as a 
cash loan of $21.4m at an interest rate of 0.75% per month. 
This loan is expected to be repaid when the guarantee is 
replaced with a bank guarantee on Ocean Infinity’s behalf 
which will then in turn be replaced by using a combination 
of SRT’s own cash resources and the UKEF export 
guarantee program. In return for providing this guarantee, 
Ocean Infinity is being granted 20,000,000 warrants* at a 
strike price of 35p, with an exercise period of 3 years.

number of financing and refinancing exercises as set out 
below:
•	
The Group has drawn down an aggregate of £5m 
of loan notes from its secured note programme as

The Group has raised an aggregate of £8.5m (before 
expenses) through the issue of 24,285,713 new 
ordinary shares*.

Annual General Meeting, provided that each proxy is 
appointed to exercise the rights attached to a different 
share or shares held by that shareholder. A proxy does 
not need to be a shareholder of the Company. If you 
are appointing more than one proxy you will need to 
state clearly on each form of proxy the number of 
shares in relation to which the proxy is appointed, and 
ensure that, taken together, the numbers of shares 
stated on the forms of proxy do not exceed your 
holding.
2.	
A form of proxy for use in connection with the Annual 
General Meeting is enclosed with the document of 
which this notice forms part. Completion and return 
of a form of proxy will not prevent a shareholder from 
attending and voting at the Annual General Meeting. 
Addresses (including electronic addresses) in this 
document are included strictly for the purposes 
specified and not for any other purpose.
3.	
To appoint a valid proxy or proxies shareholders 
must complete: (a) a form of proxy, sign it and return 
it, together with the power of attorney or any other 
authority under which it is signed, or a notarially 
certified copy of such authority, to the Company 
Secretary at the Company’s offices, or (b) a CREST 
Proxy Instruction (see note 4 below) in each case no 
later than 48 hours before the time fixed for holding the 
meeting or any adjournment thereof.
4.	
CREST members who wish to appoint a proxy 
or proxies through the CREST electronic proxy 
appointment service may do so for the Annual General 
Meeting and any adjournment(s) of the meeting by 
using the procedures described in the CREST Manual. 
CREST Personal Members or other CREST sponsored 
members and those CREST members who have 
appointed any voting service provider(s) should refer 
to their CREST sponsor or voting service provider(s), 
who will be able to take the appropriate action on their 
behalf.
In order for a proxy appointment or instruction made 
using the CREST service to be valid, the appropriate 
CREST message (a “CREST Proxy Instruction”) must be 
properly authenticated in accordance with Euroclear 
UK & International Limited’s specifications and must 
contain the information required for such instructions, 
as described in the CREST Manual. The message, 
regardless of whether it constitutes the appointment 
of a proxy or an amendment to the instruction given 
to a previously appointed proxy must, in order to 
be valid, be transmitted so as to be received by the 
Company’s agent by the latest time for receipt of proxy 
appointments set out in paragraph 3 above.
For this purpose, the time of receipt will be taken to 
be the time (as determined by the timestamp applied 
to the message by the CREST Applications Host)

from which the Company’s agent is able to retrieve 
the message by enquiry to CREST in the manner 
prescribed by CREST. After this time any change of 
instructions to proxies appointed through CREST 
should be communicated to the appointee through 
other means. CREST members and, where applicable, 
their CREST sponsors or voting service providers 
should note that Euroclear UK & International Limited 
does not make available special procedures in 
CREST for any particular messages. Normal system 
timings and limitations will therefore apply in relation 
to the input of CREST Proxy Instructions. It is the 
responsibility of the CREST member concerned to 
take (or, if the CREST member is a CREST personal 
member or sponsored member or has appointed any 
voting service provider(s), to procure that his CREST 
sponsor or voting service provider(s) take(s)) such 
action as is necessary to ensure that a message is 
transmitted by means of the CREST system by any 
particular time. In this connection, CREST members 
and, where applicable, their CREST sponsors or voting 
service providers are referred, in particular, to those 
sections of the CREST Manual concerning practical 
limitations of the CREST system and timings.
The Company may treat as invalid a CREST Proxy 
Instruction in the circumstances set out in Regulation 
35(5)(a) of the Uncertificated Securities Regulations 
2001.
5.	
Pursuant to regulation 41 of the Uncertificated 
Securities Regulations 2001 (as amended), only those 
shareholders included in the register of members of 
the Company at 6.00 p.m. January 21st 2025 or, if the 
meeting is adjourned, in the register of members at 
6.00 p.m. on the day which is two days before the day 
of any adjourned meeting, excluding any part of a day 
which is not a working day, will be entitled to attend and 
to vote at the Annual General Meeting in respect of 
the number of shares registered in their names at that 
time. Changes to entries on the share register after 
6.00 p.m. on January 21st, 2025 or, if the meeting is 
adjourned, in the register of members after 6.00 p.m. 
on the day which is two days before the day of any 
adjourned meeting, excluding any part of a day which 
is not a working day, will be disregarded in determining 
the rights of any person to attend or vote at the Annual 
General Meeting.
6.	
In order to facilitate voting by corporate 
representatives at the meeting, arrangements 
will be put in place at the meeting so that: (a) if a 
corporate shareholder has appointed the chairman 
of the meeting as its corporate representative with 
instructions to vote on a poll in accordance with the 
directions of all of the other corporate representatives 
for that shareholder at the meeting, then on a poll 
those corporate representatives will give voting 
directions to the chairman and the chairman will vote 
(or withhold a vote) as corporate representative in 
accordance with those directions; and (b) if more than 
one corporate representative for the same corporate 
shareholder attends the meeting but the corporate 
shareholder has not appointed the chairman of the 
meeting as its corporate representative, a designated 
corporate representative will be nominated, from those 
corporate representatives who attend, who will vote 
on a poll and the other corporate representatives will 
give voting directions to that designated corporate 
representative. 
7.	
As of December 4th 2024, being the latest practicable 
date prior to the publication of this document, 
the Company’s issued share capital consists of 
249,862,656 ordinary shares of 0.1 pence each with 
each share carrying the right to one vote. 
Explanatory Notes for 
Shareholders
The notice of the Annual General Meeting of the 
Company to be held at 11.00 a.m. on January 23rd 
2025, is set out on pages 55–58 of the annual report and 
accounts. The following notes provide an explanation 
as to why the resolutions set out in the notice are to 
be put to shareholders. Resolutions 1 to 7 are ordinary 
resolutions. These resolutions will be passed if more than 
50% of the votes cast for or against are in favour.
Resolution 1 – Directors’ report and audited 
accounts for 15 months ended 30 June 2024
The directors are required by the Companies Act 2006 to 
present to the shareholders of the Company at a general 
meeting the audited accounts and the reports of the 
directors and auditors for the 15 months ended 30 June 
2024. The report of the directors and the audited accounts 
have been approved by the directors, and the report of 
the auditors has been approved by the auditors, and both 
reports are contained in the Company’s Annual Report and 
Accounts.
Resolution 2 – Reappointment of auditors
The Companies Act 2006 requires that auditors be 
appointed at each general meeting at which accounts 
are laid, to hold office until the next such meeting. 
This resolution seeks shareholder approval for the 
reappointment of CLA Evelyn Partners Limited. The Audit 
Committee keeps under review the independence and

objectivity of the external auditors. After considering 
relevant information the Audit Committee recommended to 
the board of directors that CLA Evelyn Partners Limited be 
reappointed.
This resolution proposes the reappointment of CLA Evelyn 
Partners Limited as auditors of the Company. 
Resolution 3 – Auditors’ remuneration
This resolution gives authority to the directors to determine 
the remuneration of CLA Evelyn Partners Limited as 
auditors of the Company.
Resolutions 4, 5 & 6 – Directors’ re-election and 
reappointment
Neil Peniket and Simon Rogers will retire at this year’s 
Annual General Meeting and offer themselves for 
re-election. 
The articles of association of the Company require that 
any director not otherwise required to retire from office 
at an annual general meeting shall do so unless he was 
appointed or reappointed as a Director at either of the last 
two annual general meetings before that meeting. Oliver 
Plunkett, having been appointed as a new non-executive 
director of the Company following the conclusion of the 
Company’s general meeting held in connection with the 
fundraising in December 2024, will therefore retire at this 
year’s Annual General Meeting and offer himself up for 
reappointment. 
Resolution 7 – Authority to allot shares
The Companies Act 2006 provides that the directors 
may only allot shares or grant rights to subscribe for 
or to convert any security into shares if authorised by 
shareholders to do so. Resolution 7 will, if passed, authorise 
the directors to allot shares up to a maximum nominal 
amount of £83,288.
It is accordingly proposed that the directors be granted 
general authority at any time prior to the date falling 
15 months after the passing of the resolution, or, if earlier, 
at the conclusion of the Company’s next Annual General 
Meeting, to allot shares up to an aggregate nominal 
amount of £83,288, which represents an amount which 
is approximately equal to one-third of the issued ordinary 
share capital of the Company as at the date of the notice 
of Annual General Meeting. Passing this resolution will 
give the directors flexibility to act in the best interests of 
shareholders, when opportunities arise, by issuing new 
shares. The directors have no current plans to make use of 
this authority.
Resolution 8 is a special resolution. This resolution 
will be passed if not less than 75% of the votes cast 
for and against are in favour.
Resolution 8 – Disapplication of pre-emption rights
The Companies Act 2006 requires that, if the Company 
issues new shares, or grants rights to subscribe for or 
to convert any security into shares, for cash or sells 
any treasury shares, it must first offer them to existing 
shareholders in proportion to their current holdings. If 
passed, resolution 8 will authorise the directors to issue 
shares for cash and/or sell shares from treasury (if any are 
so held) up to an aggregate nominal amount of £24,986 
(representing approximately 10% of the Company’s issued 
share capital as at the date of the notice of Annual General 
Meeting) without offering them to shareholders first, and 
will also modify statutory pre-emption rights to deal with 
legal, regulatory or practical problems that may arise on a 
rights or other pre-emptive offer or issue. If passed, this 
authority will expire at the same time as the authority to 
allot shares given pursuant to resolution 7. The Company 
does not at present hold any shares in treasury.
