Filtronic plc Annual Report and Accounts 2024
Dear fellow shareholder
I am pleased to report that the year ended 31 May 2024 
has been one of significant progress. We have successfully 
capitalised on the momentum built in prior years in 
bringing to market our core technology projects and 
enhanced market focus. This culminated in the business 
securing a strategic partnership with SpaceX in addition 
to numerous contract wins with key target clients including 
BAE, QinetiQ and the European Space Agency, and our 
opportunity pipeline continues to grow across our core 
markets.
These achievements have given us an excellent platform 
to deliver long-term sustainable growth and is a major 
step forward in the execution, and de-risking, of our 
wider strategy. To that end, we will not lose sight of the 
need to focus developing business opportunities in our 
core and adjacent markets. Expanding and diversifying 
our customer base remains key to growth and resilience 
planning.
Strong trading and workforce commitment in H2 enabled 
us to deliver good growth in revenue and profit with 
material improvements seen over the prior year. We have 
kept the market and investors up to date with this dynamic 
situation by upgrading market expectations via a series of 
trading updates during the course of FY2024.
These pleasing efforts and results have enabled us 
to deliver adjusted earnings before interest, taxation, 
depreciation, amortisation and share-based payments 
(“adjusted EBITDA”) of £4.9m (2023: £1.3m), and 
significantly strengthened the balance sheet and cash 
position. This underpins our ability to invest in growing the 
operational capability to match the improved orderbook 
and extend the innovation and technology road map to 
support our collective revenue growth ambitions. 
The Markets
This year we experienced our highest levels of customer 
engagement, which reflects the growing demand for 
our core capabilities and innovative products across the 
markets we serve.
The low-earth-orbit (“LEO”) space communications 
market, whilst an emerging market, continues to produce 
sizeable opportunities from a range of prospective clients. 
The success we have had in the LEO market offers not 
only the potential for transformational growth, but also 
for us to accelerate the technology we believe this sector 
will need. Initially, this is through our innovative Cerus32 
E-band product that is being actively deployed into 
ground stations of the Starlink constellation which is 
the first and only operational commercial E-band link 
in the world today. Whilst the market is currently led by 
a small number of household names, there are many 
well capitalised companies looking to participate in this 
market with the aim of providing low-cost internet to 
remote locations and direct to cell phone capability which 
will bolster the market opportunity for us to exploit. 
The aerospace and defence industry outlook remains 
strong. There is increasing global need for high 
bandwidth, fast and secure data telemetry and 
infrastructure and we continue to explore opportunities on 
land, sea and air. As well as security and defence market 
opportunities, the private network and high-speed trading 
opportunities are a meaningful part of our current and 
future portfolio.
The telecommunications infrastructure market has 
become a less dominant part of our growth plan as the 
rollout of 5G stalls in some markets, but it remains an 
important market given the leading players tend to be 
first adopters of new technology. This ‘first to market’ 
drive helps accelerate our own technology roadmap and 
positions us well in adjacent markets where the product 
offering is highly desirable with strong revenue and 
earnings potential. 
Of critical interest and relevance to new and existing 
customers is our ability to design, develop, test and 
manufacture a turn-key solution to a high-quality 
standard, at volume. 
Scaling up our business is a key focus for the year ahead 
as we keep pace with the increased rate of trading. 
Financially, the Group’s cash position provides the means 
to make meaningful prudent investments in the business 
to facilitate further growth. We are currently exploring the 
possibility of moving to a larger facility which will offer 
more manufacturing space customised to our precise 
needs with room to expand our respective teams. We 
are also mindful that well run businesses are efficient 
and protecting profit leakage is equally important. 
Recruiting additional resource into our engineering team 
will be critical in the year ahead, to not only service the 
development needs of our current programmes, with 
their new technology requirements, but the new business 
opportunities we are pursuing.

Strategic report
www.filtronic.com  Stock Code: FTC
Financial performance summary
Group sales increased in the year by 56% to £25.4m 
(FY2023: £16.3m).
The increase in sales and a stronger sales mix, with a 
lower concentration of revenue from telecommunications 
infrastructure, led to an operating profit of £3.6m (2023: 
£0.2m) and adjusted EBITDA of £4.9m (2023: £1.3m).
The Group closed the year with £7.2m of cash at bank 
(2023: £2.6m) in addition to the availability of undrawn 
working capital debt facilities in the UK (£3.0m with 
Barclays) and the USA ($4.0m with Wells Fargo).
The Group’s net cash position, including all debt except 
right of use property leases, was £5.2m at the end of the 
financial year (2023: £1.6m). Net cash including right of 
use property leases was £4.2m (2023: £0.3m). 
Dividend
As with previous years, and after continued dialogue 
with investors the Board supports the view that the long-
term interests of shareholders are better served by cash 
being retained in the business to fund future business 
development. Consequently, no dividend is proposed for 
the year (2023: £nil).
Environmental, Social and Governance 
(“ESG”)
We are committed to building a sustainable business for 
the future, delivering consistent financial returns and long-
term value for all our stakeholders. Having formalised our 
ESG strategy last year we have made appropriate and 
meaningful progress on sustainability, building on the 
three pillars of: 
•	 Sustainable commercial enterprise;
•	 Sustainable culture and organisation; and 
•	 Sustainable environmental impact. 
Full details of the ESG strategy and objectives can be 
found on the Filtronic website at https://filtronic.com/
investors/esg-strategy/ and more detail can be found in 
the Sustainability section of the Annual Report.

Filtronic plc Annual Report and Accounts 2024
Board Composition
Following Richard Gibbs’s decision to step down from his 
role as Chief Executive Officer, the Nomination Committee 
undertook a rigorous selection process to find a suitable 
candidate to drive the business through its next phase of 
growth. We were delighted to welcome Nathaniel (“Nat”) 
Edington to the Board on 13 May 2024 as the Group’s new 
Chief Executive Officer. Nat brings a wealth of experience 
and knowledge in the electronics industry and a pedigree 
of executing growth plans. I would like to take this 
opportunity, on behalf of all of us, to thank Richard for his 
hard work, leadership and dedication over the duration 
of his tenure. Through his vision and drive, Filtronic has 
established a solid platform with a much-improved 
market position.
Outlook
The demand drivers for our business, as I have outlined 
above, remain strong and the markets we serve are 
robust. We have increasing confidence in our ability 
to deliver further growth in the year ahead, but we 
recognise the need to work fast and not be complacent. 
We will be matching our resources with the enlarged 
business that we are now operating, investing in key areas 
including exceptional and experienced engineering and 
manufacturing talent, developing opportunities with 
those in the early stages of their career and leveraging 
strong commercial relationship builders to deliver greater 
customer focus and support. We have also identified the 
essential capital equipment needed to position ourselves 
to exploit the existing and new market opportunities.
I would like to finish by thanking, on behalf of the Board, 
everyone who has contributed to the Group’s success this 
year including our talented and driven employees as well 
as our discerning and demanding customers, suppliers, 
partners and shareholders.

Strategic report
www.filtronic.com  Stock Code: FTC
I am delighted to present my first Chief Executive’s review 
covering the full year results for FY2024.  Since joining 
the business, I have been hugely impressed with the 
energy and commitment of the organisation, the deep 
understanding of RF technology and the strength of 
customer relationships with the industry leaders in our 
chosen markets of LEO space, aerospace and defence 
and telecommunications infrastructure. 
The Company has delivered an excellent set of results 
for the FY2024 trading period, and we end the year with 
revenue growing by 56% to £25.4m (FY2023: £16.3m), 
ahead of market expectations. Reported adjusted 
EBITDA also exceeded market expectations at £4.9m 
(FY2023: £1.3m), based on the strength of second half 
earnings and is a testament to the controlled scaling of the 
operating cost base throughout the trading period. We 
also close the year with a growing, healthy cash balance 
of £7.2m (2023: £2.6m).
We have invested in the long-term future of the business 
by building our IP portfolio and strengthening our 
business development and engineering teams. With a 
strengthened balance sheet and a record orderbook we 
are planning for future growth, which includes looking at 
new facilities to expand our manufacturing footprint in 
Sedgefield and the continued development of our world 
class RF engineering capability. I am excited to be leading 
the business through the next exciting phase of growth. 
We are shaping the future of microwave and millimetre 
wave communications, and a growing number of 
companies are engaging our services for the design and 
manufacture of next generation communication products. 
The ability to undertake rapid cutting-edge RF design and 
scale the manufacturing of mmWave products enables 
customers to drive performance improvement and 
accelerate time to market for demanding applications. 
Our global reputation, ability to push the boundaries of 
what is possible in RF design and the service offering of 
a turnkey solution to design and manufacture remain 
the key competitive advantages that Filtronic provides to 
customers in our strategic markets.
RF design is a complex engineering discipline requiring 
a highly specialised set of design skills and deep 
understanding of analogue design principles. Critical to 
our success is the recruitment and retention of world class 
RF engineers. Filtronic has over 45 years’ experience in 
the RF market and unrivalled history of innovation and IP 
development. The ability to offer exciting careers working 
at the leading edge of RF technology with the world’s 
leading communication and aerospace companies has 
proved essential in our ability to attract the talent we need. 
We have successfully coupled our engineering 
expertise with investment in state-of-the-art production 
equipment that enables the rapid transition from product 
development to full scale manufacturing at volume. The 
addition of dedicated engineering lines to create new 
processes without disrupting mainstream operations, has 
greatly improved delivery of engineering programmes 
and allowed us to move at the speed our customers 
demand. The move to a new purpose-built manufacturing 
facility would significantly improve the efficiency of our 
manufacturing operations and enhance our ability to 
meet future scale-up opportunities.
In the last twelve months Filtronic has released several new 
high-power products for use in the telecommunications 
and LEO space market based on specific customer 
requirements. We end the year with a healthy number of 
new product developments in the engineering pipeline, 
and a well-defined technology roadmap aligned with 
both customer and future market requirements. 
Chief Executive’s review

Filtronic plc Annual Report and Accounts 2024
During my first few months in post, I have seen first-
hand the strength of relationships with Filtronic’s 
strategic customers, who are amongst the leaders in 
their respective markets. The engagement with SpaceX, 
with whom we signed a five-year Strategic Partnership 
in April 2024, demonstrates the value we bring to all of 
our clients. Leveraging our engineering capabilities, and 
the responsiveness and speed of execution to develop 
product and ramp manufacturing output quickly, we were 
able to take the Cerus 32 SSPA product from concept to 
volume production in less than six months, in this rapidly 
evolving market.
Customers and Markets
Our mission at Filtronic is to enable the future of RF, 
microwave and mmWave communications, and our focus 
markets are those that operate at the leading edge and 
offer growth potential for our products. The strategic 
markets we are serving of LEO space and aerospace and 
defence remain the focus of our investments where we can 
add significant value, and where we can realise long term 
sustainable margins and deliver shareholder value. 
The LEO space market is growing rapidly as the costs 
associated with the launch and deployment of satellite 
technology continues to dramatically reduce. Well-
funded, private corporations like SpaceX, together 
with established global aerospace contractors and 
ambitious regional start-up companies, are racing to 
build constellations of satellites that will accelerate the 
delivery of internet and ‘direct to cell’ services across 
the globe. Gateway communications between the LEO 
satellite and the ground enable convergence with the 
established terrestrial telecommunication networks, that 
in turn provide the world with high speed, low latency 
and ubiquitous connectivity. Filtronic’s leadership as a 
supplier of compact, highly integrated, and extremely 
reliable telecommunication backhaul solutions position 
us well to respond to the aggressive timelines demanded 
by the leading players in the LEO space market. The 
ability to design and build SSPAs, at multiple frequency 
bands, enabled Filtronic to win initial production orders 
with SpaceX for the deployment of the first LEO space 
E-band backhaul communication links in early 2023. 
Over the past year we have successfully built on this 
relationship to establish a Strategic Partnership to secure 
supply of E-band SSPAs and work in partnership to 
develop the technology roadmap associated with the 
Starlink constellation over the next five years. In July we 
announced our first follow-on order since announcing our 
partnership; a new contract worth $9.0m (£7.1m).
The accelerating convergence of ground-based 
telecommunications with LEO space enabled connectivity, 
will continue to drive demand for efficient use of high-
performance terrestrial telecom solutions. Increasing 
demand for high power transceiver modules and custom 
power amplifier solutions for private telecommunication 
networks, demonstrates significant adjacent market 
opportunities for Filtronic.
The aerospace and defence market has been a consistent 
long term revenue contributor to Filtronic over the years, 
and our technology is well adapted for use in electronic 
warfare (“EW”) applications associated with Active 
Electronically Scanned Array (“AESA”) radar. We have 
retained a position in the aerospace radar market with 
the supply of hybrid transmit/receive modules and highly 
customised filter designs. Whilst supply to this market 
has seen a hiatus, we remain well positioned for strategic 
airborne radar programmes that will follow in the next 
few years once procurement decisions have been made 
by several governments. In FY2024, after a long selling 
cycle, we were successful in winning contracts in both 
land-based radar and maritime radar applications 
from QinetiQ and BAE respectively. In addition to radar 
applications, we have continued to make inroads into the 
UK defence market for the supply of next generation RF 
communication products. Following an initial engagement 
with Defence Science Technology Laboratories (“DSTL”) 
for the delivery of our first battlefield communications 
product in FY2022, we were successful in winning an 
additional two DSTL programmes in FY2023 and a 
fourth programme in FY2024. Battlefield communication 
solutions are evolving quickly, with commercial space 
and telecommunication technology augmenting the 
legacy defence communication solutions. Our DSTL 
engagements will align us closer with UK MoD strategic 
requirements and ultimately provide consistent and long-
term revenue streams for highly customised products.
Outlook
We operate in a world with an ever-increasing demand 
for broadband connectivity, and with it the search for 
opportunities to open additional RF spectrum. Filtronic is 
the leader in the field of millimetre wave solutions, and we 
benefit from the fact that the expertise we offer is in short 
supply.
Filtronic’s strategic markets represent industry verticals 
that have a robust outlook and align well with the needs of 
the post-pandemic world. Public safety, mobile 
telecommunications, sovereign defence capability and 
the rapid development of LEO space networks, are 
well funded sectors that resonate with governments, 
investors, and the public at large. Alongside the growth 
opportunities for the business generated from the SpaceX 
partnership, our pipeline with other customers and in other 
focus markets is also healthy and increasing, providing 
good growth opportunities across our markets and 
customer base.

This investment in our internal capabilities will ensure 
we manage more customers, and projects with perfect 
execution. As we build the organisation, priority will be 
on building the engineering, programme management 
and commercial teams. As we execute on these key areas, 
we will ensure robust financial governance, as well as 
ensuring we remain nimble, flexible and fast moving.
The addition of a new CEO, in Nat Edington, with a track 
record in execution of growth strategies for technology 
businesses, brings a renewed energy to the business. 
This energy will be harnessed to augment the culture of 
the Group whilst providing an opportunity to review the 
strategy with a fresh perspective and new ideas.
Creating value
Our purpose and mission define our strategy and provide 
the framework in which our strategic focus lies.
Our vision is clear, to be known for enabling the future of 
RF, microwave and mmWave communication. This is a 
bold statement but one in which we firmly believe given the 
strength of our capabilities and successes in pushing the 
boundaries of technology. We have developed technology 
that have been world firsts and achieved world leading 
status with data speeds. 
Our mission is to create value for our clients through 
technology leadership. We develop the building blocks 
of core IP and then utilise this technology to create 
highly customised solutions for our core markets. Our IP 
starts with the chipsets we use in our systems which are 
developed in-house and designed to perform better than 
what is available from commercial off the shelf (“COTS”) 
products. This gives our technology a competitive 
advantage over our competitors. We then use these chips 
in our core product offering where we are seen as leaders 
in the technology with substantial know-how having 
been operating at very technically challenging frequency 
bands for over 15 years. There are design houses that 
have capability and there are manufacturers that can 
process the technology, but Filtronic can offer end-to-
end capability with turnkey solutions where we design, 
engineer and manufacture solutions.
The strategy remains focussed on organic growth 
to capitalise on opportunities in expanding markets 
including LEO space, aerospace and defence and 
telecommunications infrastructure. These are markets 
where there is significant government and industrial 
investment in the technology that the Group provides.
In the satellite communications market, we are a trusted 
partner and supplier to the space industry, as evidenced 
by our long-term agreement with the market leader, 
SpaceX. Our mmWave technology for LEO applications 
in both ground stations and payload is helping accelerate 
our customers’ entry into this market. We continue to 
penetrate and work with other leaders in this market and 
have already been successful in multiple projects with 
the European Space Agency (“ESA”), opening up future 
commercial opportunities.
Within aerospace and defence, we provide RF, microwave 
and mmWave solutions that are critical for sensing, 
protecting and communicating in areas such as Electronic 
Warfare and AESA radar. Here, military satellite 
communications is also a fast growing opportunity, and 
we are already applying our market leading components 
and subsystems in this area. We have long established 
specialised hybrid manufacturing capabilities, and this 
remains a growth area for us.
These are our two key strategic markets that we deliver 
growth by:
•	 Developing long-term customer partnerships;
•	 Encouraging innovation and advancement of 
technology;
•	 Identifying and pursuing growth opportunities in new 
and existing markets; and
•	 Developing high-quality leadership teams and a 
high-performance culture in our organisation.
We continue to support our legacy markets of 
telecommunications infrastructure and critical 
communications, and we expect these to be good 
contributors to our business for years to come, but the 
other strategic markets are now driving our growth. 
Telecommunications infrastructure will always be 
an important market for us as it drives much of the 
technology roadmap. Whilst it is very price sensitive, 
technology tends to be adopted first by this market, which 
enables adjacent market opportunities for us.
We have a well-defined, focused technology roadmap 
and strategy that will ensure we remain a key player in 
microwave and mmWave communications products 
for years to come. In order to execute these technology 
developments at pace, we also utilise the research and 
academic community along with our industrial partners, 
as an extension of our internal expertise. We have 
demonstrated the ability to have technologies available 
for key customers ahead of their requirements, and also 
influenced their product plans, which is testament to our 
deep expertise in the RF arena.
We will continue to operate as a technology and 
manufacturing company, in markets that align with 
our mission and purpose, and invest to capitalise on the 
significant levels of market demand that we are seeing in 
our opportunity pipeline.

Filtronic plc Annual Report and Accounts 2024
The business delivered a break-through set of 
results with significant improvement in revenue, 
profit and cash reflecting the successful execution 
of our strategy. The strong performance provides 
the platform to invest in the long-term growth of 
the Group with momentum building from customer 
demand and pipeline opportunities.
FY2024 saw major progress for the Group, with the 
signing of a Strategic Partnership with SpaceX offering 
potential for significant growth. Revenue growth in the 
year of 56% and adjusted EBITDA growth of 285% to 
£4.9m (2023: £1.3m) saw the Group upgrade market 
expectations a number of times in the year as trading was 
very strong in H2. Revenue growth initiatives continue to 
be the major benefactor of investment as we capitalise 
on market opportunities and deliver on key strategic 
objectives, particularly to broaden the customer base and 
increase revenue in the markets we serve. Whilst there 
have been economic headwinds in the wider economy, we 
have benefitted from operating in core markets such as 
space and aerospace and defence, that are seeing huge 
investment and are high on the priority of government 
spending plans. 
Revenue
Group revenue increased to £25.4m (2023: £16.3m) 
with the emerging market of LEO space driving much 
of the growth, mainly due to SpaceX rapidly deploying 
and expanding their Starlink constellation. As more 
subscribers are added to the network, bandwidth and 
low-latency become critical to the end-user experience 
and therefore more E-band SSPAs are needed to keep 
pace with the network rollout and new user additions. 
Whilst we announced significant order wins in the year to 
strategically important customers such as the European 
Space Agency, BAE Maritime and QinetiQ, revenue 
in FY2024 has not benefitted from any meaningful 
recognition of these contracts, which are expected to 
positively impact FY2025 and beyond.
Our LEO space customer Space X, contributed 48% of 
revenue in FY2024. We are mindful of the short-term 
consequence on customer concentration and dependency 
arising from this. The three largest customers represent 
84% of turnover (2023: 73%). However, we are confident 
that this will rebalance over time as the sector develops 
and we continue to win business in other markets. 
As expected, the 5G telecommunications infrastructure 
market has seen a slowdown in demand coupled with 
the original equipment manufacturers (“OEM”) holding 
excess inventory. This led to sales to this sector decreasing 
year-on-year by 12% but whilst the cyclical nature of the 
market meant we were down in the period, we still see this 
market as an important one for the Group, particularly 
as we continue to push the boundaries of innovation 
and technology with our customers, who are often early 
adopters of new technologies.
Sales of Xhaul products to other markets were up 77% 
on the prior year mainly due to three new customers that 
we won orders from covering a range of end markets 
including high-frequency trading platforms and private 
networks. These products are a blend of E-band 
derivative technology products that have been customised 
from our core offering and use of our highly automated 
process capability.
Aerospace and defence revenue was lower than the prior 
year by 49% due to a hiatus in supply of components to 
airborne radar systems from an established programme. 
This is a timing issue with demand expected to return 
as new aircraft orders are received. Despite this, the 
underlying fundamentals in this market remain strong and 
it is fully expected that significant growth will be delivered 
over FY2024 in the coming year based on order intake 
and opportunity pipeline. This is a key market to our 
growth plans, and we are investing to further penetrate 
within the defence primes and the Ministry of Defence 
(“MoD”). Our technology is highly relevant and the skills we 
offer are in short supply within our key target customers 
who are all expressing a need to engage with SMEs 
who can offer sovereign capability. This is supported 
by the MoD which has placed increasing importance 
on maximising small and medium sized enterprises 
(“SME”) integration into defence procurement, not only to 
invigorate the sector and shorten the supply chain, but to 
ensure the defence industry has access to the innovation 
and technologies that SMEs develop.
The legacy products supplied into the critical 
communications market saw demand return to 
normalised levels after upstream component issues within 
the system-level product last year. This resulted in an 
increase of revenue to this market of 53%. This increase 
was seen throughout the product portfolio we offer to the 
P25 network in the USA including the TTA product.

Operating costs and headcount
Operating costs increased by 25% in the year to £12.5m 
(2023: £10.0m) as investment increased to realise the 
growing opportunity pipeline. The key area of spend was 
in our engineering organisation where we increased the 
headcount, particularly in Q4, and worked with partners 
to undertake product developments on a variable cost 
basis. In addition to this, the annual bonus target was met, 
having not been achieved in the prior year, whilst we also 
increased manufacturing overhead to facilitate the rapid 
ramp of production in H2. 
As mentioned above, the annual bonus performance 
target was met in the year as the directors and key 
management were rewarded for achieving a stretch 
revenue target. This bonus will be paid in August 2024 
payroll, after publication of the audited accounts, but has 
been accrued in the FY2024 financial statements. We 
also implemented a one-off bonus in FY2024 for all of our 
employees who were not already part of a variable bonus 
scheme, based on the achievement of the same stretch 
target given the effort needed to enable the production 
ramp.
The Group’s largest overhead is salary-related costs, 
representing 67% of the operational cost base, which 
increased by 22% lifting overheads by £1.5m, accounting 
for much of the overall operating cost uplift. The mix of 
our manufacturing employees shifted from lower cost 
production operatives to higher cost specialist engineers in 
process engineering who are critical for implementing new 
products and processes. 
Engineering resource is key for our growth, and it was 
pleasing to see that we not only increased the number of 
engineers, but also the quality and quantity of candidates 
we are attracting with valuable expertise and experience, 
which has helped to significantly upskill the team from 
the prior year. This has enabled us to service a larger 
opportunity pipeline, increase the number of product 
developments for customers and expand our technology 
roadmap, to position us well to execute our strategic plans.
Given some of the changing dynamics described above, 
the headcount increased to 133 (2023: 130) at 31 May 
2024 with a mix change from manufacturing to research 
and development. An analysis of the Group’s headcount is 
presented below:

We are planning to add further business development 
resource in FY2025, to augment our direct access 
to market, whilst we also plan to bring in additional 
engineering resource to deliver scheduled programmes 
and accelerate new product delivery. Investment in 
the engineering team is critical to sustainable financial 
growth and we plan to maintain this spend at around 
13% of revenue. Given the speed of revenue growth and 
relative difficulty in recruiting RF engineers quickly, this 
number was around 11% this year (2023: 13%) despite 
an increase in engineering costs of £0.8m. Continuing 
to focus on this metric will ensure we have the resource 
in place to capitalise on growth opportunities and keep 
ahead of our competitors with the latest technology.
Where product development is customer specific, we 
seek to receive a Non-Recurring Engineering (“NRE”) 
charge to maintain a healthy flow of cash during the 
development phase of the engineering projects and 
ensure commitment from our customer. When developing 
our own technology roadmap and IP, we invested from 
our cash reserves. This was the case when we developed 
technology for the LEO space market, and we’ll develop 
further technology from our own reserves at a range of 
other frequencies in both ground station applications 
and the payload. Consequently, we capitalised £0.7m of 
development costs in the year. Further commentary on 
these capitalised development costs can be seen in the 
Research and Development section of this review.
Other costs increased in line with scaling a business 
including recruitment fees, equipment hire and insurance 
costs whilst electricity costs reflected a new fixed term 
contract having concluded the contract that was locked in 
prior to inflationary pressures in the energy industry.
The Group continues to be active in securing grant 
funding to further support growth initiatives and 
investment. We benefitted from a further £0.15m of 
grant income in the year from the Defence Technology 
Exploitation Programme (“DTEP”) and local support from 
Business Durham for the purchase of some key machinery. 
Looking forward, we are engaged in a number of open 
calls in both regional funding programmes and national 
technology grants that we hope to be awarded in the next 
year.
Adjusted EBITDA
The Group utilises an alternative performance measure 
(“APM”) to track performance of the business. This 
APM is adjusted EBITDA as it measures the quality of 
earnings without the impact of non-cash expenses such as 
depreciation, amortisation and share-based payments. 
Share-based payments have been added to the APM this 
year, having been calculated as part of IFRS2 fair value

Executive Directors and key management. More details of 
this can be found in note 30. 
Adjusted EBITDA for the year was £4.9m (2023: £1.3m) 
representing a 285% increase whilst operating profit was 
£3.6m (2023: £0.2m) representing a 1,423% uplift. This 
was the result of stronger gross profit from higher revenue, 
whilst the sales mix was also stronger due to a reduction to 
the concentration of low margin 5G telecommunications 
equipment which is a highly price sensitive market.

Taxation
A tax charge of £0.2m (2023: tax credit of £0.4m) was 
recognised in the year, as deferred tax assets were 
amended to recognise a shorter period of asset usage. 
The Group also benefits from R&D tax credits, due to 
the advancement of science and technology in the new 
products we develop, which lowers the amount of taxable 
profit on qualifying R&D activities. We also make use of 
the Annual Investment Allowance (“AIA”) which offers 
tax relief on capital expenditure purchases, and utilise 
first year allowances on capital purchases above the AIA 
threshold.
With substantial deferred tax assets, including those 
not recognised on the balance sheet, the Group will 
continue to benefit from not having a tax liability for the 
foreseeable future.
Research and development costs (“R&D”)
Total R&D costs in the year before capitalisation 
and amortisation of development costs were £2.8m 
(2023: £2.0m). The Group incurred engineering costs 
on a mixture of customer funded developments and 
progression of the technology roadmap.
The Group remains committed to investing in R&D for 
future growth and consequently measures R&D spend 
as a KPI. Key areas of spend in the year included product 
development for LEO space applications in both the 
ground station and the payload, private networks and 
aerospace and defence. The year ahead will see us 
continue to invest in the development of our own strategic 
technology roadmap and proprietary IP, enabling us to 
build long-term shareholder value in the years ahead.
Recruitment of RF engineers has been an industry-wide 
issue for some time, but we are pleased with recent 
successes in attracting new talent to the business at each 
of our three UK engineering development sites. We will 
augment this by building an organisation fit for the future, 
increasing the intake of graduate recruits and augmenting 
our apprenticeship programme.
The Group capitalises its development costs in line with 
IAS 38 as set out in note 1 to the financial statements. 
A reconciliation of R&D costs before capitalisation and 
amortisation can be seen in the table below:

When capitalising development costs, an impairment 
review is undertaken of each development programme to 
test the carrying value does not require impairment in line 
with IAS 36.
Capital expenditure and right of use assets
Capital expenditure in the year remained in line with 
the prior year, with investments focussed on automated 
test capability which enables the R&D team to engineer 
at higher frequency bands, critical for execution of the 
strategic plans. The total amount of capital purchased 
was £1.5m (2023: £1.5m).
Warranty provision
In line with industry practice, the Group provides 
warranties to customers over the quality and performance 
of the products it sells. Reflecting a full risk analysis 
of current commercial contracts at 31 May 2024, the 
warranty provision was £0.4m (2023: £0.3m).
Funding and cash flow
The Group recorded an increase in cash and cash 
equivalents to £7.2m (2023: £2.6m) at the year-end. Cash 
generated from operating activities in the year was £6.3m 
(2023: £1.0m) as adjusted EBITDA performance drove 
cash generation and customers prepaid an element of 
the contract value for product development of bespoke 
solutions.
Net cash, when including all debt except property leases 
at the end of the period, was £5.2m (2023: £1.6m), whilst 
overall net cash including property leases was £4.2m 
(2023: £0.3m). 
We also have additional cash headroom available 
through a £3.0m invoice discounting facility with Barclays 
Bank plc in the UK. We had a $4.0m invoice factoring 
facility with Wells Fargo Bank in the USA but terminated 
this agreement on 12 July 2024. Both facilities were 
undrawn at 31 May 2024 (2023: undrawn).

Going concern
In assessing going concern, the Board have considered:
•	 The principal risks faced by the Group which are 
discussed within the ‘Risk management’ section of the 
Annual Report;
•	 The financial position of the Group including forecasts 
and financial plans;
•	 The healthy cash position at 31 May 2024 of £7.2m 
(2023: £2.6m) and the additional headroom available 
through the undrawn invoice discounting facilities and 
overdraft (2023: undrawn); and
•	 Economic headwinds with the potential for customers 
to reassess their priorities, with opportunities 
postponed or curtailed.
Following the above considerations, the directors are 
satisfied that the Group has adequate financial resources 
to continue in operational existence for a period of at least 
12 months from the date of this report. Accordingly, the 
going concern basis has been adopted in the preparation 
of the Annual Report for the year ended 31 May 2024.

Approach to managing risk 
The Board is ultimately responsible for the overall risk 
management system and internal controls applied 
throughout the Group to ensure a structured and 
appropriate approach to risk is taken in line with 
strategic priorities and risk appetite. The Audit and 
Risk Committee has oversight of risk management 
and reports to the Board with its findings. The directors 
recognise that risk is inherent in any business so actively 
manages rather than eliminates risk to achieve business 
objectives which includes review of the effectiveness of 
these controls.
Risk management within the Group is managed by the 
Risk Management Committee made up predominantly 
of the Senior Leadership Team including the Executive 
Directors. 
The team is responsible for:
•	 Identifying the risk and the negative and positive 
risk circumstances;
•	 Assessing and evaluating the likelihood and impact 
of those risks;
•	 Reporting the risk; and 
•	 Managing the key risks in accordance with 
established processes under the Group’s 
operational policies and controls. 
This process includes a regular review of the Group’s 
risk register considering existing and emerging risks, 
risk scores and mitigation action plans prepared by 
risk owners to manage and reduce the risk. Reporting 
within the Group is structured so that key issues can be 
escalated rapidly through the management team to 
the Board where appropriate.

The Board recognises strong risk management is key to our success and achievement of our 
strategic objectives. A rigorous assessment of the principal risks facing the Group is regularly 
undertaken with quick and effective responses taken when needed. These principal risks carry 
financial, operational and compliance impacts including those that threaten the business model, 
strategy, future performance, solvency and liquidity. They are identified based on the likelihood of 
occurrence and the severity of impact on the Group that could result in damage to our reputation or 
business performance.

Change 
in year
Our ability to remain competitive in terms of technology 
and product design is underpinned by retaining key 
employees, talent acquisition and effective design 
methodologies.
We work closely with our customers and suppliers to gain 
a thorough knowledge of the technology being developed 
in the marketplace. We are also members of key forums 
such as The European Telecommunications Standards 
Institute (ETSI). By staying close to the market, we position 
ourselves to react quickly to any technology changes that 
develop.
When undertaking new product developments, we 
follow a process which facilitates a thorough review 
of the engineering development at various milestones 
throughout the project. This methodology is designed 
to ensure the product has no design defects, meets the 
required specification and is on time to exploit the market 
opportunity. We have a project management team to 
ensure compliance with our engineering development 
process and have plans to further strengthen this function 
in FY2025.
In order to protect our intellectual property, we maintain 
and apply for patents when appropriate and actively 
encourage innovation in our engineering team through a 
reward process.
The markets we supply into are 
time-sensitive and opportunities 
may be lost if we fail to achieve 
customer specification or meet 
the timescales required to match 
market demand. This may also 
impact on future revenue.
For products in the production 
cycle, technology insertion is often 
required as a means of achieving 
cost reductions to improve 
product margins.
Our product competitiveness is 
heavily influenced by technology 
choices at product concept stage 
and throughout the execution 
of design to product launch. If 
the technology we develop is 
inappropriate this could result in 
missed opportunities.
Failure 
to deliver 
projects on 
time or to 
specification
Our principal risks and uncertainties
In a market of rapid technology changes, it is imperative 
the Group chooses opportunities that will yield a good 
rate of return and have an extended product life. All new 
opportunities are appraised to ensure there is a good 
match between our capacity, capabilities and likely 
adoption in a growing market with a good rate of return.
The appraisal process includes regular communication 
with our customers including key members of our 
engineering teams to ensure we are developing innovative 
products that deliver the technical solutions needed by the 
market. This process also assists in the formulation of the 
technology roadmap to ensure it is aligned to the needs of 
our customers which augments the work we undertake to 
develop our own market intelligence.
With the rapid evolution of 
product technology and other 
corporate decisions, the size of 
our addressable market may 
be affected. Failure to forecast 
market movements correctly thus 
missing opportunities or wrongly 
predicting product longevity 
could impact on long-term 
revenue and profit.
Failure to 
identify 
market 
requirements
Managing new emerging risks 
We monitor new and emerging risks closely. In the year, 
we have not added recruitment to our risk register as we 
are trying to scale the business to manage a growing 
opportunity pipeline and the number of projects we are 
managing. We have downgraded the risks relating to 
semiconductor shortages as the global component crisis 
is now behind us and cost inflation which is now under 
control. Therefore, we have removed these risks from 
principal risks and uncertainties.
Risks also present opportunities as well as potential 
downside; the challenge to scale our business with 
talented people not only represents a risk, but also an 
opportunity is it builds our internal capacity and 
bandwidth to manage more projects to achieve our 
growth plans.
We have mitigating plans to cover each of the risks we 
are managing and met regularly as a Risk Management 
Committee to discuss these material  risks.
In the year ahead, our priorities are focussed on 
broadening the customer base and winning new clients 
in our strategic markets. We will also be working to 
ensure we build capacity in our engineering teams to 
minimise the risk that project timelines are not met, given 
the volume of programmes we are actively managing 
to support customers and develop our own technology 
roadmap.

Our largest customers are very successful in their 
respective markets, and each has a long-established 
relationship with Filtronic. We continue to win further 
contracts with our existing customers, including the 
strategic partnership with SpaceX, and have good 
outlook visibility as well as being actively engaged with 
them on new opportunities. 
The Group has strong account management 
strategies and mitigates this risk by working closely 
with customers, at all levels, to ensure that we are 
designed into their new products at an early stage, 
enabling us to develop products that meet their 
specifications and requirements.
We provide customers with a well-resourced 
programme and a high level of service with a focus 
on product quality and delivery which enables high 
customer retention rates. 
To broaden the customer base, we won several 
contracts with new customers in the year, including 
BAE, QinetiQ and the European Space Agency, across 
several different markets that may lead to significant 
business in the future. In the short-term the risk has 
increased due to significant order intake from SpaceX 
driving revenue growth.
Having strengthened the business development 
function in FY2024, we are looking to strengthen 
further in FY2025 in both the direct and indirect 
channels, giving confidence this risk can be reduced.
Our revenue is currently weighted 
towards our largest customers.
The loss of any of these 
customers, material reduction in 
orders from any such customer or 
the timing of customer projects 
may have a material adverse 
effect upon Filtronic’s financial 
condition. 
Reliance 
on key 
customers
The Group has a highly competitive remuneration 
package that is reflective of market conditions for key 
roles and is under review as conditions change. For an 
insight into the benefits package the Group offers please 
see the ‘Our people’ section of this report. The Group also 
operates a long-term incentive plan for key employees 
and a SAYE scheme for all UK employees. 
We continue to invest in our engineering teams to ensure 
we have engineers with the right skills to execute our 
strategy. We also provide regular communications to all 
employees through communication meetings in each 
of our business locations along with a newsletter to 
employees giving updates about business performance. 
By giving our employees an understanding of our 
strategic direction and objectives, we believe it 
enables them to make meaningful contributions to the 
achievement of our goals.
The Group is reliant on the key 
skills and knowledge of its people 
in a range of areas especially in 
the engineering function. Failure 
to recruit, develop and retain an 
appropriate number of suitably 
qualified people in critical areas 
could affect our ability to design 
new products and meet our 
customers’ needs. Due to the 
highly technical nature of our 
activities, these skills are not 
always readily available which 
could have an adverse effect on 
the Group.

Exceptional people allow us to create exceptional 
products and solutions for our customers, and the markets 
we serve. We are proud to have employees who are just 
that. Our engineering and operations teams are very 
highly regarded by both domestic and international 
customers and other stakeholders alike. 
Our workforce is exceptionally stable; we have an average 
length of service of over 8 years and an employee turnover 
rate of under 2%.
	
               
Employee Communication and Engagement
On a regular basis, management engages with our 
employees through a range of formal and informal 
channels, including briefings and memos from the 
Executive Directors, team meetings, 1-2-1’s, and online 
publications via various social media outlets. 
We consider an open and honest culture critical to success 
and continuous improvement and have an open door 
policy throughout the business to encourage informal 
conversations and accessibility. 
Through our HR system we have also enabled surveys 
covering key aspects of employment such as onboarding 
and equality, diversity and inclusion. Voluntary leavers are 
interviewed to provide an additional means of expressing 
their views enabling us to analyse data to address any 
retention issues or implement suggested improvements.
Equality, Diversity and Inclusion (“EDI”)
EDI is embedded in our culture; procedurally and 
behaviourally from recruitment, employee development, 
succession planning through to pay audits. We want to 
reflect the local communities in which we operate and the 
diversity in our workforce is largely representative of this. 
Filtronic has equal opportunity policies which form part 
of the Group’s core values and which are expected of 
employees, suppliers and other stakeholders. Our policies 
and practices emphasise the importance of treating 
people in a non-discriminatory and inclusive manner 
across the full employment life cycle. 
Our workforce gender split is, female 35%: male: 65%. 
The majority of technical and managerial positions are 
held by men. We continue to work towards addressing 
this and increasing the number of technical, managerial 
and leadership positions held by women. This is a 
challenging target as the engineering sector is still very 
much male dominated particularly in the UK,  but we 
have had success this year recruiting female engineers 
internationally. 
We are confident that our university and apprentice 
scheme partnerships  will assist us in placing more women 
into technical roles.
Employee Remuneration 
Our compensation strategy aims to attract and retain 
talent whilst promoting and rewarding sustainable 
performance and contributions at all levels of the 
organisation. The Board and the Remuneration 
Committee continually look to ensure that our 
remuneration provisions support our strategy and 
business objectives.
The market competitiveness of salaries across the 
company is assessed at local or national market level, 
dependent upon role, and is reviewed annually. A full 
salary benchmarking exercise was undertaken this 
year for all roles, with significant increases made to 
manufacturing salaries, to ensure that we recruit and 
retain the highest quality candidates in this area.
In addition to competitive salaries, we also offer a suite of 
benefits including, but not limited to, employer matched 
pension contributions plus 2%, to a maximum of 8%, long-
term incapacity benefit, 4 x base pay sum life assurance, 
childcare vouchers, cycle to work scheme, electric vehicle 
scheme and paid time off for charity work.
We love to encourage innovation within our business, the 
Technology Leadership Recognition policy aims to do 
this by recognising and rewarding innovative thinking 
and professional personal development. A number of 
awards were made in the year, under this scheme, for new 
patent applications and grants as well white papers and 
technical presentations. To complement this, we have also 
introduced a ‘Bright Ideas’ scheme managed through our 
T-card system, to broaden the reward scope for new ideas 
and continuous improvement suggestions. Vouchers are 
presented quarterly to employees with the best ideas.
We also like to reward loyalty and offer an additional 
days’ holiday every five years to a maximum of 15 years. 
After this, we gift a long service award to our employees 
recognising their commitment to the Company, and 
celebrate their commitment with an awards ceremony at 
our annual summer event.

We are extremely proud of our people and their contribution in supporting organisational performance 
and strategy.

their gross salary before tax and national insurance with no 
up-front cost, whilst also saving the planet! This will also help 
the business in striving to achieve sustainability.
What does a ‘day in the life’ look for you?
As a Management Accountant, my tasks vary based on what 
the business needs each day. At month-end, I focus on putting 
together the monthly management accounts, comparing 
actual results with forecasts, and analysing the P&L and 
Balance Sheet to present to key stakeholders.
What I enjoy most is working with the sales and production 
teams to review and fine-tune forecasts. It’s satisfying to ensure 
they’re reliable, set targets, and figure out ways to tackle any 
issues. Running the weekly sales forecast meetings leading 
up to the year-end was particularly rewarding because our 
teamwork helped us hit our target—a great win for the whole 
Filtronic team.

What do you love most about your job?
One of the aspects I love most about my job is the daily opportunity to 
learn and grow, benefiting from the knowledge and expertise of my 
colleagues. Being surrounded by experienced professionals exposes me 
to innovative solutions to design problems and challenges. This dynamic 
environment allows me to apply the theoretical knowledge from my day 
release at Sunderland University to practical situations, enhancing my 
understanding and communication skills.  I also value the collaborative 
atmosphere within the team, where my contributions are appreciated 
and my growth is encouraged. The blend of hands-on experience and 
continuous learning makes my apprenticeship incredibly fulfilling.
What was it about the Filtronic Apprentice scheme that 
attracted you?
Similar to any apprenticeship, Filtronic lured me in by the opportunity 
to work in such a unique sector of electrical engineering as not many 
people can say they contribute towards products used for satellite 
communications - something that everybody interacts with in some form. 
Further to this, the opportunity to work in a really good engineering team 
with vast knowledge, experience and feels  
like a family. Plus, working towards a degree,  
whilst working a full-time job is a real opportunity!
What tools do you use day to day?
No two days are the same in my job, day-to-day I get to use the latest CAD software and RF/microwave measurement 
hardware that we have here in the labs. I use CAD to model and analyse the predicted performance of the high-frequency 
modules we design at Filtronic. Additionally, I get to use all our top-of-the-range lab equipment, such as signal generators, 
spectrum analysers, and oscilloscopes, to measure and test prototypes of our products. I really enjoy this thorough testing 
process and getting to see something through from beginning to end. It is really satisfying to see our prototypes meet our high 
standards before they proceed to operations.
What have you learnt since working for our company?

The Group’s engagement with key stakeholder groups 
and the impact our business operations have on the local

the implementation of the Company’s Strategy and the 
Sustainability report.
The Board carefully considers stakeholder interests when making decisions on strategically important 
matters as the directors discharge their duties in alignment with Section 172.
Section 172 (1) Statement 
UK Companies Act 2006
In compliance with the 
Companies Act 2006, the Board 
are required to act in accordance 
with a set of general duties. The 
Board consider that they have 
individually and collectively 
acted in a way they consider, in 
good faith, would be most likely 
to promote the success of the 
Company.
To achieve long term success, 
the Board recognises the 
importance of building and 
maintaining relationships 
with key stakeholders as 
well as considering the likely 
consequences of its decisions in 
the long-term.
Regular updates from 
the executive Senior 
Leadership Team (“SLT”)
Throughout the year, the 
SLT updated the Board with 
information on important areas of 
business focus, in particular those 
relating to our key stakeholders. 
The SLT is made up of the Chief 
Executive Officer, Chief Financial 
Officer, Chief Commercial 
Officer, Chief Operating Officer, 
Chief Technology Officer, 
Director of Engineering, Chief 
Scientist and the Head of HR. 
They each submit a report each 
month providing comprehensive 
operational updates and progress 
against strategic milestones. 
They are periodically invited 
to board meetings to present 
this information and update 
the Board on key points. This 
ensures the Board have a good 
understanding of the priorities 
of each stakeholder group to aid 
decision making at board level.
Direct engagement of 
Board members
The Executive Directors are in 
daily contact with employees from 
across the business to understand 
key topics involving employees, 
customers and suppliers which 
are regularly shared with the 
Board. Regular reporting of 
customer engagement keeps the 
Board up to date on customer 
trends and feedback. A number 
of board members had meetings 
with shareholders during the 
year to discuss strategy, business 
performance and executive 
incentives.

How we engage
Key outcomes
Customers
The Board receives feedback from its customer facing 
teams. Each key account has a dedicated account 
management who acts as “the voice of the customer”. 
The Chief Commercial Officer briefs the Board each 
month as to how we are performing with each of our 
customers.
The Executive Directors, along with senior members of 
the sales and engineering teams will attend meetings 
with strategic-level influencers within our customer’s 
organisation.
We continually seek opportunities to collaborate at 
a product and technology strategy level with our key 
clients, but all collaborations are under Non-Disclosure 
Agreement (“NDA”) and require director-level approval.
Customer feedback is regularly sought and collected 
by the business through a wide range of channels. This 
information is processed and analysed as part of our 
business improvement initiatives.
We regularly participate in a wide range of trade 
shows, conferences and symposia. They play an 
important role in our business development planning.
 
The Executive Directors communicate with employees 
through communication sessions and town hall 
meetings to update them on the performance of the 
business and progress on key initiatives. Employees are 
encouraged to ask questions in a Q&A session at the 
end of the meetings.
The Group relies upon highly specialised skill sets 
that are in increasingly short supply. We are therefore 
continually developing our talent management 
strategy.
Increased levels of engagement with customers at 
a strategic level. A greater understanding of both 
customer and market trend requirements better 
informs the development and refinement of our own 
strategy and technology roadmap to ensure we 
support our customers to the best of our ability and 
invest in the right capability to meet their needs.
Board-level engagement with our customers helps 
convey our commitment to understand and meet their 
business needs. Having customers onsite enables 
them to see our capability and production facilities 
demonstrating our credibility as a leading technology 
company.
Disclosure of our product development and 
technology roadmaps to customers increases 
the opportunity to align our mutual interests and 
demonstrate we are the ‘go-to company’ when it 
comes to leading technology; the NDA protects our 
intellectual property interests.
Listening to the customer enables us to be more 
effective in pre-empting and meeting their evolving 
requirements. We undertook a Voice of the Customer 
(“VoC”) exercise during the year where the Marketing 
Manager spoke to 35 existing and former customers 
to gain an understanding of their customer 
experience, the positives of working with Filtronic and 
areas where we could improve. The information was 
anonymised, collated and analysed to find trends 
to identify consistent feedback. This exercise proved 
invaluable enabling the Board to use the information 
to shape the strategic plans and develop the areas of 
the business where we are able to improve customer 
satisfaction.
Attendance at trade exhibitions and conferences has 
materially increased over the last year as we have 
added more events to our roster to actively promote 
the business. This has facilitated key engagement, 
not only with prospective customers, but also having 
useful discussions with our existing clients.
Broad ranging and meaningful communication leads 
to greater transparency throughout the business and 
facilitates a more engaged, motivated and effective 
team. This is done through a range of communication 
channels including newsletters, emails to all employees 
and discussion groups with management flow down 
to employees and informal factory floor-walks.
The Group is an attractive employer, providing 
a rewarding long-term personal development 
opportunity environment, recognising and rewarding 
those that have demonstrated strong performance. 
We have also funded a number of training initiatives 
to develop our employees and enhance the skills in the 
business including the Filtronic Leadership Academy 
to upskill all  staff who have managerial responsibility.
The Board recognises its responsibility to take into consideration the needs and concerns of Filtronic’s key stakeholders 
as part of its decision-making process. The table demonstrates how the Group engages with its stakeholders and the 
outcomes of this during the year:

and offer an open-door policy to employees who 
would like to ask a question or offer a view. 
Participation in the Company Sharesave scheme.
The Chief Executive Officer and Chief Financial Officer 
hold analyst and investor meetings throughout the 
year both on request and specifically following the 
release of the annual and half year results. Feedback 
from these meetings is shared with the Board. Major 
shareholders are regularly engaged to hear their views 
on a range of issues such as strategy, remuneration 
and corporate governance.
The Annual General Meeting is our primary method 
of engagement with private investors along with the 
Annual Report. We encourage investors to attend 
and ask questions they may have. At the end of the 
meeting, the Board engage in an open and informal 
forum with attendees.
The Group’s Annual Report and Accounts is available 
to shareholders in both hard copy form and online. 
All announcements and presentations are available 
on the Company’s website whilst we also engage on 
social media platforms such as LinkedIn. There is also 
a regular newsletters which is sent to those individuals 
that signup on the company website.
The Company’s broker, Cavendish Capital Markets 
(“Cavendish”), provides briefings to the Board on 
shareholder opinions and independent feedback from 
investor meetings. Their views are sought on all market 
related matters or announcements.
Meetings are held with key suppliers at both their 
facilities and ours. This ensures a more intimate 
knowledge of each other’s capabilities and objectives 
and leads to closer alignment of values.
Our Supplier Code of Conduct is flowed down to 
our supply chain to ensure compliance with social 
responsibility and good governance policies.
A better informed and consulted workforce is more 
likely to be both better motivated and more effective.
The Group also operates a T-card system where 
employees can offer ideas for business improvements 
which are shared with the Executive Directors with the 
aim of offering feedback to those that have taking the 
time to share their views and a quarterly prize for the 
best idea. The Board have also approved an annual 
employee engagement survey to gain insight into 
employees’ thoughts and attitudes towards their work 
and overall environment.
Share scheme participation aligns the interests 
of employees with shareholders giving staff the 
opportunity to hold a stake in the company. The 
Company has a SAYE scheme in place which is open to 
all employees.
A wide range of communication channels are used 
to engage with investors during the year. Feedback 
from investors has informed the Board’s discussions 
and decisions on the Company’s strategy. All material 
information that is worthy of investor announcement 
is made available simultaneously to both shareholders 
and potential shareholders. Meetings with 
shareholders and potential investors were held during 
the year with meetings offered both in person and 
virtually.
We value the opportunity to meet with our shareholders 
and engage in an exchange of views and ideas and, 
post AGM, we review the feedback we have received. 
We were delighted to welcome shareholders to the 
2023 AGM which was physically held in Sedgefield with 
private investors encouraged to attend.
We respect that not everyone is online and continue to 
provide shareholders with a choice to receive a hard 
copy of the report.
Regular and frequent interaction between the 
Company and our broker ensures we receive regular 
guidance and remain aligned on our engagement 
with the investment community. A report collated 
by Cavendish, after the business results investor 
roadshow, giving shareholders feedback from each 
meeting is shared with the Board.
The Group’s supplier base is a key part of the 
Company’s ecosystem and effective relationships with 
our suppliers are essential to the delivery of Group 
performance. We engage with our suppliers through 
our engineering and operations team and we work 
closely with key suppliers to ensure we take advantage 
of innovative technical and commercial solutions 
in the supply chain in order to secure a competitive 
advantage. We have enjoyed meetings at a number 
of suppliers’ sites in the year, both nationally and 
internationally.
We minimise our exposure to supplier related risks 
by requiring them to adhere to our Supplier Code 
of Conduct and group policies. They are required 
to confirm they are not in conflict with these policies 
before or during engagement.

Filtronic plc Annual Report and Accounts 2024
Improving our sustainability performance plays a key role 
in the way we both run our businesses today and plan for 
the future, as we manage our ESG-related risks. We also 
recognise that our ESG credentials are an increasingly 
important factor in our ability to attract and retain first-
class people. Engaged, motivated, empowered and 
appropriately skilled employees are integral to our success.
Whilst our approach to sustainability continues to mature, 
we are committed to implementing transparent policies 
and procedures, and to fostering an inclusive culture 
across the Group where everyone does the right thing 
and takes responsibility for their actions. Increasingly this 
focus will develop from working as a trusted partner to our 
many customers and ensuring that our internal standards 
are fit for purpose, to working with our supply chain to 
ensure that they too work to the same standards. In doing 
so we will build a sustainable company of which all our 
stakeholders can be proud, now and in the future.
Our approach to sustainability
The long-term success of Filtronic can only be enhanced 
by a positive interaction with all of our stakeholders and 
therefore a positive and engaged approach to corporate 
responsibility and sustainability is important to us. Our 
approach is focused around the environment, people, 
ethics and business conduct and governance.
ESG Responsibility
Sustainability forms part of our everyday thinking, from 
how we run our business from day to day, to long-term 
strategic planning. ESG is now a regular, scheduled 
board agenda item and a 
standing agenda item for every 
meeting of the Group’s Senior 
Leadership Team.
2024 has seen us make further 
progress as we proactively 
manage our sustainability 
agenda. Focus areas included 
diversity and inclusion, 
reducing climate change, 
employee wellbeing and 
community engagement. As 
a business we are committed 
to building a sustainable 
company of which all our 
stakeholders can be proud, 
both now and in the future.
Operating our business in a way that cares for the environment and people has never been more important 
than it is today. The world is facing significant environmental and social challenges with climate change, 
environmental destruction, energy availability and increased costs of living.

on natural resources. As well as operating in compliance 
with all relevant statutory and regulatory obligations, the 
Group strives to implement environmental best practices 
throughout our activities and continually improve our

Scope 1 & Scope 2 emissions  
We are pleased to present, for the first time, our figures 
for the reporting of our Scope 1 and Scope 2 emissions, 
equating to a 35% reduction from our base year in 
FY2023. 
As a company quoted on AIM, there is no obligation to 
report on Scope 1 and Scope 2 CO2 emissions but to 
maintain a good level of transparency we are voluntarily 
disclosing information. We recognise our duty as a good 
corporate citizen, to help in the fight against climate 
change, and take this obligation seriously. We also 
understand our investors eagerness to understand how we 
are performing in our commitment to protect the planet by 
preventing pollution and minimising our impact on natural 
resources. The table below presents our Scope 1 and 
Scope 2 emissions. 
Emissions for the Group
We are at an early reporting phase in that we have not 
defined our scope or targets when comparing to ‘The 
Greenhouse Gas Protocol: A Corporate Accounting and 
Reporting Standard’ and therefore these figures are 
an early attempt to quantify our GHG emissions. We 
recognise our obligation to help with the climate crisis, 
along with the interests of our key stakeholders, and 
therefore we recognise the importance of giving visibility in 
our environmental reporting.
We intend to improve the accuracy of the numbers over 
time and will engage with a third-party consultant to take 
the relevant advice on how to refine and augment the 
approach we have taken. The numbers in the table are 
taken from our metered gas usage, reported car journeys

in STEM days involving local schools and colleges. We 
now have STEM Ambassadors employed in the business 
who are qualified to attend STEM days, representing 
Filtronic, to inspire the next generation of engineers in our 
community. We want to encourage more of our talented 
team to become STEM Ambassadors and will be rolling 
out an incentive programme across the business to 
encourage additional participation and representation.  
We also saw the first intake of apprentices on our new 
apprenticeship programme which provides quality 
employment for young people in the local community. 
We are training our apprentices through a mix of ‘on the 
job’ training and full sponsorship to degree level at local 
universities. These are fantastic opportunities for talented 
local young people to have access to a high-quality jobs 
complemented with higher education, and they in turn 
enrich our culture through diversification, new perspective 
and pure enthusiasm! We make use of the apprenticeship 
levy to help fund this initiative. Investing in this community 
helps us to build a broader and more diverse pool of talent. 
We also continued our established graduate programme 
with another successful intake this year.
We made progress in our talent acquisition strategy and 
have seen an increase in nationalities diversity, rising from 
12% to 14%. We have ensured that all of our employment 
practices and policies are female friendly and will continue 
with any positive actions possible which may further 
improve our success in increasing female representation 
throughout the business.
Recognising the extraordinary efforts of the entire Filtronic 
team to deliver revenue growth of 56%, we implemented 
a one-off bonus for all of our staff who each earned the 
equivalent of £1,000 pro rata based on service in the 
year. Ensuring our employees are paid competitively 
in recognition of their enormous value to us, is of great 
importance to our retention strategy. In the year, we gave 
a general pay award above inflation to all employees to 
recognise the importance of them to our growth ambitions 
and an inflation-busting award to our manufacturing 
operatives. This is in recognition of the skills they possess 
and to pay them a salary that keeps their salary at a 
competitive level in respect to the rest of the manufacturing 
community in the north-east of England.

Governance objectives
Filtronic have always believed that sound governance is 
fundamental to the long-term success of the Company 
and we follow the QCA Corporate Governance Code 
which gives a firm foundation for our governance 
structure. Having been listed on the London Stock 
Exchange since 1994, the business has a robust approach 
to governance, but we can always strive for improvement.
 
The Board and our management team will drive the ESG 
agenda. We recognise that good governance will be key 
to ensuring the changes are embedded throughout the 
business.
Compliance is critical to our operation, particularly as 
we supply into sensitive markets such as aerospace and 
defence , and therefore strong governance is at the heart 
of how we conduct business. 
This year we received the news that the IASME 
Governance Gold certification is awarded to the top 
3% of applicants for the IASME accreditation. This is 
something we are very proud of and demonstrates the 
quality of our cyber security credentials and robust 
governance framework that we operate. We feel this is a 
great segway into the ISO27001 accreditation that we are 
looking to commence implementing in FY2025. To test our 
cyber defences, we undertook a series of cyber security 
exercises including a regular phishing exercise to ensure 
our employees are well-educated on the latest phishing 
attacks being conducted in addition to a series of desktop 
exercises with the National Cyber Security Centre.
We also added a new policy in the year to our Group 
Policies to set our governance standard relating to Anti-
Competition and Anti-Trust following a question from a 
customer relating to our policy. We have also undertaken 
some early action following the update to the QCA 
Corporate Governance Code in 2023 which includes 
publishing our remuneration policy for the first time in this 
Annual Report and implementing annual re-election of 
directors at the AGM in October 2024.
We will continue to augment our governance standards in 
FY2025 and ensure we operate the business with an ethos 
of ‘doing the right thing’ for all of our stakeholders and the 
communities in which we conduct business.

Dear Shareholder
I am pleased to present the Filtronic plc Governance report 
for the year ended 31 May 2024.
The Board recognises the value of good corporate 
governance as the basis for promoting the long-term 
growth and sustainability of the business. Governance 
arrangements are reviewed on an ongoing basis to 
ensure they are fit for purpose and the Board continues to 
consider that the Quoted Companies Alliance Corporate 
Governance Code 2018 and the updated QCA Corporate 
Governance Code 2023 (the “Code”) provides the most 
appropriate framework for governance for the Company’s 
size and complexity. We intend to implement all of the 
recommendations in the updated version of the Code. 
Throughout the year, we complied with all principles of the 
Code except for the separation of the Company Secretary 
role which is currently undertaken by the Chief Financial 
Officer. 
The Governance report includes the Corporate 
governance statement, the Audit and Risk Committee 
report, the Nominations Committee report and the 
Directors’ remuneration report and describes how Filtronic 
has applied the main principles of the Code during the 
year. Further information on compliance can be found on 
the Filtronic website at www.filtronic.com/investors. 
I am aware that it is my responsibility to ensure that 
Filtronic has the governance arrangements in place to 
support effective leadership and promote the long-term 
success of the Company and that these arrangements are 
followed in practice. 
Jonathan Neale,  
Chairman 
29 July 2024
Corporate governance statement
Introduction
The Board acknowledges the role that the ten QCA 
Code principles has in providing structure to the Group’s 
corporate governance framework. This section explains 
how we have adopted the QCA Code, including those 
provisions where we do not currently comply.
Principle 1 – Establish a strategy and business model 
which promotes long-term value for shareholders
As explained fully within the strategic report of the Annual 
Report, our strategy is focussed around four core areas:  
•	 Space: position Filtronic in the Space market (LEO/
HAPS) by strengthening our position in the market 
having already secured a Strategic Partnership with 
SpaceX;	
•	 Defence: increasing defence project coverage with 
major customers requiring RF hybrid solutions; 
•	 Aerospace: leveraging our current relationships to 
secure a bigger role in next generation radar design;
and
•	 Telecommunications infrastructure: defending 
our current position and target new customers by 
developing the E-band roadmap to W-band with 
premium performance high power transceivers, 
active diplexer and SiP options based on inhouse 
MMIC design; 
The delivery of the strategy remains the focus of the 
Board’s attention. Our objective through the execution of 
the strategy is to deliver shareholder value and medium-
long term growth. As a Board, we will ensure that we 
continue to challenge ourselves and regularly consider 
whether we are effective in delivering this objective.
Our business model and execution of the strategy is 
underpinned by the governance framework outlined in this 
section.
Principle 2 - Seek to understand and meet 
shareholder needs and expectations
Great value is taken from maintaining open relationships 
with our shareholders and the primary point of contact 
in the Company for this function is the Chief Executive 
Officer (“CEO”), supported by the Chief Financial Officer 
(“CFO”) and the Chairman. 
The CEO and CFO undertake an extensive programme 
of individual meetings with shareholders at least twice a 
year. Additionally, the Chairman is available to speak with 
shareholders at their request. The Senior Independent 
Director is also available as an alternative communication 
channel for shareholders who may wish to raise any 
concerns. 
Presentations are also made to analysts to present 
the Group’s results. This assists with the promotion of 
knowledge of the Group in the investment marketplace 
and also helps the directors to understand the needs and 
expectations of shareholders. The Group’s website has 
a dedicated investor section to assist all shareholders. 
Investors are welcome to send any questions or queries to 
investor.relations@filtronic.com.
When the Board considers it appropriate, it consults with 
shareholders on key matters that it would like input relating 
to strategy, governance and remuneration.
Principle 3 - Take into account wider stakeholder and 
social responsibilities and their implication for long- 
term success
The Group takes its corporate social responsibility 
very seriously and is focussed on maintaining and 
strengthening effective working relationships across 
a wide range of stakeholders including shareholders, 
employees, customers and suppliers. 
Our stakeholder engagement recognises the materiality 
and impact of our stakeholders on the achievement of the 
Company’s strategy. The Section 172 (1) Statement and 
Stakeholder engagement sections within the Governance 
report provide more information on this. 
The success of the Group’s strategy is part built upon the 
Governance report

maintenance of internal and external relationships and 
good communication with stakeholders.
Principle 4 – Embedded objective risk management 
considering both opportunities and targets 
throughout the organisation
The Group faces challenges in the execution of its business 
strategy. The Board acknowledges that it has overall 
responsibility for the Group’s system of internal controls, 
which is designed to manage and mitigate rather than 
eliminate risk, and to review and monitor its effectiveness. 
The Audit and Risk Committee have been delegated 
responsibility to oversee risk management, and 
undertakes regular reviews of the Group’s risk register with 
a view to:
(i) 	 ensuring the risk register is complete, appropriate 
and up to date; 
(ii) 	 ensuring adequate processes are in place to detect 
new or emerging risks; 
(iii) 	reviewing risk exposures and any changes to the 
status of risks in the risk register; 
(iv)	 reviewing risk management assessment and 
processes; 
(v) 	 reviewing risk mitigation measures and the 
appropriateness of responses to risks; 
(vi)	 reporting its findings to the Board.  
Risk management, together with a robust set of systems 
and internal controls are well established within the 
business. The Risk Management Committee, made up 
of the Senior Leadership Team in the business, meet on a 
regular basis to maintain and review the risk register.
A comprehensive business planning process is also 
completed on an annual basis including the long-range 
plan which are reviewed and approved by the Board. This 
ensures the resources in the Group are correctly aligned 
with the business strategy. In addition, the Group conducts 
regularly re-forecasts to ensure resources are aligned to 
the ongoing needs of the business. During the year, the 
Group’s results are compared against the business plan 
which is reported monthly and discussed at each meeting 
of the Board.
Principle 5 – Maintain the board as a well-
functioning, balanced team led by the Chairman
The Board is currently comprised of:
•	 the Non-Executive Chairman; 
•	 two Executive Directors; and
•	 two Non-Executive Directors
The Non-Executive Directors are regarded by the Board 
as being independent Non-Executive Directors. 
The role of Company Secretary is currently undertaken 
by the CFO. In compliance with the Code, the Board is 
mindful of the need to develop plans to separate the roles 
of CFO and Company Secretary at an appropriate time. 
Board members are also able to take independent 
professional advice at the Company’s expense in the 
discharge of their duties.
There is a formal schedule of matters reserved for 
the Board. To enhance the Board’s communication 
with management and achieve greater operational 
transparency, senior management from the sales and 
marketing, operational and engineering organisations are 
periodically invited to the board meeting to present their 
key projects and deliverables. 
Board meetings
The Board meets each month against a defined reporting 
timetable and at times in between the scheduled meetings 
when required. Board meetings are held at the Group’s 
operational sites to enable local management teams to 
present operational and strategic programme progress 
to the Board. The Board believes this arrangement 
gives greater transparency and enhanced relationships 
between the management and the Board. During the 
year, board meetings have been held in person at the 
Sedgefield, Yeadon and Manchester sites.
Directors’ attendance FY2024
The Board normally schedules at least 10 meetings during 
the year. Last year the Board met formally 10 times.

Principle 6 – Ensure that between them directors 
have the necessary up-to-date experience, skills and 
capabilities
At present, the Board is satisfied that its overall size and 
composition reflects an appropriate balance of sector, 
financial and public markets skills and experience. The 
composition of the Board is reviewed at least annually 
by the Nominations Committee, with a view to ensuring 
it comprises the skills necessary for executing the 
Company’s strategy.
Details of each director’s skills and experience can be 
found in the directors’ biographies section. The members 
of the Board bring a range of complementary skills and 
experience from across markets in which the Group 
operates. 
Each member of the Board takes responsibility for 
maintaining their skill set, which includes formal training 
and seminars. The directors have also received briefings 
and training in respect of AIM rules compliance and 
Market Abuse Regulations. The board undertakes annual 
training on a range of subject matters that are proposed 
by the directors where they feel it would be beneficial.
When necessary, external advice is sought, on legal, HR, 
financial and governance matters. The primary sources 

Filtronic plc Annual Report and Accounts 2024
46
are the Company’s Nomad and the Company’s lawyers.
Principle 7 - Evaluate board performance based on 
clear and relevant objectives, seeking continuous 
improvements
The Board carries out an evaluation of its own 
performance at the end of each financial year, reviewing 
its performance in that year.
The Chairman and the Company Secretary prepare an 
evaluation questionnaire reflecting the considerations 
of the corporate governance code as well as significant 
events over the year. 
The performance of the Board and its Committees is 
assessed. Board members are asked to provide feedback 
for assessment by the Chairman. The combined feedback 
is discussed by the Board and actions agreed with 
progress updates during the year.
As part of the Director’s induction process the Company 
Secretary arranges an induction session with each new 
director covering such matters as:
•	 Group and organisation structure, 
•	 Filtronic’s values and group policies, 
•	 an introduction to the AIM Rules for Companies, 
•	 the QCA Code, 
•	 Market Abuse Regulation (“MAR”) and the terms of 
reference for the Board’s committees. 
Where specific training needs are identified, including as 
a result of the Board evaluation process and individual 
director appraisals, the Company will organise the 
relevant training. The Company Secretary supports the 
Chairman in addressing the training and development 
needs of directors. 
Principle 8 – Promote a corporate culture that is based on 
ethical values and behaviours
At Filtronic, we believe in collaboration, we work with our 
technology leadership clients to solve their complex RF, 
microwave and mmWave challenges. 
Our purpose and reason for being is to be the trusted 
provider of innovative RF solutions. Innovation matters to 
us, we want to push the boundaries of what is possible with 
RF communication. 
Filtronic are long-term partners in space, aerospace and 
defence, telecommunications infrastructure and critical 
communications. These effective partnerships have 
grown from having a strong value-based culture, where all 
our employees are encouraged and supported to:
•	 Act with integrity; being honest, always keeping our 
promises.
•	 Be respectful to all; it is the foundation of our culture.
•	 Strive for excellence; it is what our clients and 
colleagues expect and what we endeavour to 
deliver.
The Board monitors and promotes its corporate culture 
assisted by the SLT, which includes the Head of HR. This 
team plays a vital role in disseminating the Company’s 
shared values with its employees. The SLT holds monthly 
meetings, and its members are frequently invited to attend 
sections of the board meeting which helps the Board 
assess the Group’s culture on an ongoing basis.

processes that are fit for purpose and support good 
decision making by the Board
The Board, led by the Chairman, is committed to a high 
standard of corporate governance across the Group, 
recognising its importance in protecting shareholders’ 
interests and long-term success of the Group.
Remit of the Board
Whilst many day-to-day operational matters are 
managed by the Executive Directors and SLT, other 
matters, including those listed below, are reserved for the 
Board:
•	 Strategy and oversight of the management of the 
Group;
•	 Review of business performance and delivery of 
results;
•	 Approval of the Company and consolidated 
financial statements;
Governance report continued

Governance report
47
www.filtronic.com  Stock Code: FTC
•	 Approval of major corporate transactions and 
commitments;
•	 Succession planning (appointment/removal of 
directors, PDMRs and the Company Secretary);
•	 Approval of all terms of reference for the committees 
of the Board;
•	 Review of the Group’s overall corporate governance 
arrangements including systems of internal controls 
and risk management; and
•	 Approval of the distribution of authority.
Committees
The Board is supported by three committees: 
•	 Audit and Risk Committee;
•	 Remuneration Committee; and
•	 Nominations Committee. 
Detailed written terms of reference for each committee 
are maintained and are available to view on the company 
website. 
In addition to formal meetings, the Nominations 
Committee and Remuneration Committee also meet 
informally during the year to review and discuss board 
composition and compensation.
Principle 10 - Communicate how the Group is 
governed and is performing by maintaining a 
dialogue with shareholders and other relevant 
stakeholders
The Company is committed to open communication 
with all of its stakeholders. Communication with 
shareholders is driven primarily through:
•	 the regulatory news service (“RNS”), 
•	 the Filtronic website;
•	 the Annual General Meeting; and 
•	 meetings after the Group’s interim and full year 
preliminary accounts. 
All shareholders receive a copy of the Annual Report 
and Accounts either as hard copy or electronically 
depending on shareholder preference. Copies of 
historic annual reports and notices of general meetings 
for the last five years are available on the Filtronic 
website, as are the half-year results.
Engaging with our employees helps to ensure the 
values and culture the Board wants to promote are 
embraced throughout the Group. The Company 
encourages open two-way communication to promote 
innovative and collaborative working. Communication 
with employees takes place ordinarily through town 
hall meetings at each of the Company’s sites, the HR 
system, team meetings, health and safety meetings 
and training sessions. 
The longevity of our business can only be secured 
through maintaining and expanding our customer 
base. Communication with customers is a priority and 
is mediated through dedicated commercial managers 
and directors, overseen by the Chief Commercial 
Officer. Customers are solicited for feedback on 
products and business operations performance, 
market landscape and demand trends.
Regular contact and openness is key to maintaining 
good and stable relations with our supply chain. The 
procurement department, aided by clear website 
sections, ensures that Filtronic’ s key policies and 
values, or their equivalent, are adopted by the supply 
chain with all suppliers issued with the Filtronic Supplier 
Code of Conduct which includes, but is not limited to, 
its policies on issues such as bribery, modern slavery 
and conflict minerals. Engagement with suppliers is 
overseen by the Chief Operations Officer. 
The group policies were reviewed by the Board during 
the year and, as a priority for the business, were 
communicated, via management cascade, to all 
employees.

Dear Shareholder
I am pleased to present the Nomination Committee 
report for FY2024. 
The Nomination Committee supports the Board on 
the crucial topic of Executive and Non-Executive 
succession planning. Our principal objective as a 
Nomination Committee is to make sure the Board and 
the wider management team has individuals with the 
necessary range of skills and knowledge, and diversity of 
experiences to lead the Company and deliver the Group’s 
strategy.
The Committee plays a vital role in ensuring the 
effectiveness of the Board and its ability to deliver 
long-term success for the business, including having the 
appropriate balance of skills, experience and knowledge 
on the Board to both reflect the changing needs of the 
business and anticipate and prepare for the future.
This year the Committee continued its focus on succession 
planning with an emphasis on ensuring plans were in 
place for an orderly succession following Richard Gibbs 
advising us of his intention to retire from the Group. 
Following a rigorous search process, having appointed a 
highly reputable search firm to assist in a targeted search 
and assessment, we were delighted to unanimously 
recommend Nat Edington as the new Chief Executive 
Officer, joining the Board on 13 May 2024. Richard has 
agreed to remain with the business until 30 November 
2024 in order to facilitate an orderly transition.
The Committee also took account of the results from 
the annual board performance evaluation exercise 
conducted in June 2023. The Committee plays a key role 
in ensuring the effectiveness of the Board and its ability 
to deliver long term success for the Company. As the 
Chairman of the Committee, I review the results of this 
exercise and share the feedback with the members of 
the Board both individually to personalise the feedback 
and as a collective. Nothing significant was raised as part 
of this evaluation but some improvement actions were 
identified which are highlighted below:
•	 Succession planning which becomes more important 
as the business scales in size; and
•	 Continuing to keep under review the combined role 
of the CFO and Company Secretary with a plan to 
decouple the role at the appropriate time.
•	 A greater emphasis on the role of diversity and 
inclusion and the important role it plays in high 
performance organisations;

Governance report

In the year ahead, the Committee will continue to work 
on succession plans for the Board and key management 
and to oversee any actions coming out of the board 
effectiveness questionnaires that took place in June 2024 
to ensure they are effectively implemented.

New appointments and induction of directors 
When identifying suitable candidates for board and 
senior executive appointments, the Committee uses the 
services of external advisers to facilitate the recruitment 
search and considers candidates on merit and against 
objective criteria. The Committee recognises the value of 
a diverse board and will consider all candidates with the 
necessary capabilities in accordance with the Company’s 
policies including considerations of equality and diversity.
When a new director joins the Board a full and formal 
induction process is undertaken including a briefing 
session on AIM rules with our Nomad. The Company 
Secretary is tasked with providing the new director with: 
•	 information about the Group including board and 
committee minutes along with board papers from at

Dear Shareholder
I am pleased to present the report of the Audit and Risk 
Committee.
The Audit and Risk Committee continues to fulfil a vital 
role in the Group’s governance framework, providing 
independent challenge and oversight of the accounting, 
financial reporting and internal control processes, 
risk management, the internal audit activity and the 
relationship with the external auditor. This report outlines 
how the Committee has discharged its responsibilities 
during the year, including the onboarding of a new 
auditor. It aims to provide shareholders with a clear 
understanding of the work we have done as a committee 
to provide challenge and assurance on the integrity of 
the FY2024 Annual Report and Accounts and the Group’s 
regulatory reporting requirements as well as the key 
issues it has considered.
Meetings are generally held immediately prior to a board 
meeting to facilitate immediate and efficient reporting to 
the Board, with additional meetings where necessary. The 
Executive Directors may attend the meeting by invitation 
whilst the external auditors attend when requested, as do 
outsourced internal audit providers when used.
The Company outsources its internal audit activity to third 
parties as it is not deemed appropriate given the size 
of the Company to have its own internal audit function. 
However, the Audit and Risk Committee considers 
annually whether there is a need for an in-house internal 
audit function to be established and, were it to conclude 
that this would be more appropriate than the current 
arrangements, would recommend this to the Board. 
This year, the Committee focussed on completing the 
tender process that was undertaken in the year resulting 
in the appointment of Crowe U.K LLP (“Crowe”) as 
external auditor. The Group has worked with Crowe on 
the transition activities and has now completed the first 
year of the Group and Company audit. The Committee 
also had updates on cyber security controls which is a 
risk area that the Committee wants to keep a focus on 
although the results are very positive with a strong set of 
robust controls in place. 
The normal pattern of meetings follows the public 
reporting and audit cycle, with meetings to consider the 
external audit plan; the half year announcement and the 
full year Annual Report and Accounts, the latter with the 
external auditors’ observations and opinions. There are at 
least two additional meetings in the year to review the key 
risks within the Group, how they are managed and review 
the adequacy of the arrangements to mitigate those risks. 

Governance report
51
www.filtronic.com  Stock Code: FTC
There is also a meeting to consider the internal audit that 
has taken place in the year.
As Chair of the Committee, I maintain regular dialogue 
with the Chief Financial Officer and have direct access to 
Crowe, the Company’s external auditor. The Committee 
meets separately at least once a year with the external 
auditor without others being present to facilitate open 
discussion and the opportunity to discuss any concerns.
Next year, in addition to the normal cycle of matters 
that the Committee schedules for consideration, we are 
planning to: 
•	 Undertake an internal audit of the financial internal 
control system;
•	 Engage a cyber security specialist to once again test 
the resilience of our cyber security systems; and
•	 Continue to monitor emerging risks in the Group.
As Chair of the Audit and Risk Committee I make 
myself available at the Company’s AGM to answer any 
shareholders questions relevant to the Committee.

Activities of the Audit and Risk Committee during the year
During the year, the Audit and Risk Committee discharged its responsibilities by: 

Filtronic plc Annual Report and Accounts 2024
52
Fair, balanced and understandable
The Company’s management and the auditor confirmed 
to the Audit and Risk Committee that they were not 
aware of any material misstatements. Having reviewed 
the reports received from management and the auditor, 
the Committee is satisfied that the key areas of risk and 
judgement have been appropriately addressed in the 
financial statements and that the significant assumptions 
used in determining the value of assets and liabilities have 
been properly appraised and are sufficiently robust. 
After careful consideration of the advice of the Audit 
and Risk Committee, the Board has concluded that the 
2024 Annual Report and Accounts is fair, balanced and 
understandable and provides the necessary information 
for the Company’s shareholders to assess the Group’s risks, 
performance, business model and strategy.
Risk management and internal controls
Risk and risk management is delegated to the Audit and 
Risk Committee although the overall responsibility for the 
Group’s system of risk management and internal controls 
remains with the Board.
The Group has well established risk management and 
internal control processes that have been developed 
since Filtronic was formed in 1977. The Audit and 
Risk Committee confirms that the effectiveness of the 
system of internal control, covering all material controls 
including financial, operational, commercial and 
compliance controls and risk management systems, 
have been reviewed during the year. Further details of 
risk management can be found in the Risk management 
section of this Annual Report on page 23.
Auditor independence
Both the Audit and Risk Committee and Crowe have 
procedures in place to avoid the auditors’ objectivity and 
independence being compromised.
The Committee performs its own assessment of auditor 
independence satisfying itself on an annual basis that 
suitable policies and procedures are in place to safeguard 
the auditors’ independence and objectivity. This includes 
having regard to length of service, provision of non-audit 
services and the existence of any conflicts of interest. 
On the latter point, the Company has a policy of not 
employing anybody from the audit firm within five years 
of their departure. The auditor also has open access to 
the Chair of the Audit and Risk Committee and open lines 
of discussion with the Committee to ensure there is no 
influence by management.
Rotation of lead audit partner
As part of their review of auditor independence, Crowe 
has confirmed that it is independent of the Company 
and has complied with applicable auditing standards. 
Crowe is in its first year as auditor and therefore the 
Audit and Risk Committee report continued
Significant issue
Key accounting matters
The following key areas of risk and judgement have been identified and considered by the Audit and Risk Committee in 
relation to the business activities and financial statements of the Group and Parent Company:
Significant issue
Committee action taken
Carrying value 
of goodwill and 
other intangible 
assets
The Committee considered the judgements made in relation to the valuation methodology 
adopted by management and the model inputs used. These are set out in note 14 to the financial 
statements.  
The Committee agreed with the judgements made by management and concluded that no 
impairment of goodwill should be made in the financial statements of the Group.
Filtronic operates in an industry where developments in product technology and the highly 
customer specific nature of some inventory may result in inventory becoming slow-moving or 
obsolete. This in turn may mean that inventory cannot be sold or sales prices for such inventory are 
discounted to less than the relevant inventory’s book value.
The Committee considered a paper from management analysing this inventory by product and 
looked at projected future usage relative to current inventory on hand. It reviewed the provision for 
excess and obsolete inventory and noted that the level of provision and the methodology applied 
was appropriate and consistent.
Inventory 
valuation
Capitalisation 
and impairment 
of intangible 
development costs
The Committee considered the capitalisation of development costs and the impairment 
assessment prepared by management. It critically assessed the inputs, such as a consideration 
of the reasonableness of discount rates applied and of reviewing forecasts into individual 
development product projections.
The Group’s accounting policy for intangible assets is included within the accounting policies 
in note 1 and the components of intangible assets are set out in note 14. The products under 
development, and capitalised, are mainly mmWave technology focussing on space opportunities 
which are expected to give rise to future economic benefit. Intangible asset impairment 
calculations and sensitivities are undertaken at least annually by management.

Senior Statutory Auditor is operating in accordance with 
professional guidelines of serving no longer than five years 
to maintain independence. 
External auditor
The Committee considers that Crowe has carried out its 
duties as the auditor in a diligent and professional manner. 
In assessing the auditor’s effectiveness, the Committee:
•	 Challenged the work done by the auditor to test 
management’s assumptions and estimates in the key 
risk areas;
•	 Reviewed reports received from the auditor on these 
and other matters;
•	 Received and considered feedback from 
management; and
•	 Held private meetings with the auditor that provided 
the opportunity for open dialogue and feedback 
between the Committee and the auditor without 
management being present.
Having completed its review, the Audit and Risk 
Committee is satisfied that Crowe remained effective and 
independent in carrying out its responsibilities up to the 
date of signing this report. 
Appointment of the auditor
Crowe were appointed as external auditor to the Group 
in the year, with Michael Jayson being appointed the lead 
audit partner for FY2024.
Whistleblowing
The Group has in place a Whistleblowing policy, which 
sets out the formal process by which an employee, or other 
stakeholder, may, in confidence, raise concerns about 
possible malpractice in financial reporting, conduct or 
other matters to an identifiable whistleblowing officer.
There were no incidents or concerns raised for 
consideration during the year.
Anti-bribery
The Group has in place an Anti-Bribery policy, which 
sets its zero-tolerance position. The policy provides the 
principles for employees and other stakeholders that acts 
as guidance on how to recognise and deal with issues that 
may be considered as giving rise to bribery.
During the period there were no incidents reported that 
required consideration.

Dear Shareholder
On behalf of the Board, I am pleased to present the 
Filtronic Directors’ remuneration report for the year 
ended 31 May 2024. The report explains the work of the 
Remuneration Committee during the year and sets out the 
payments and awards made to directors. 
The recently updated QCA Code recommends that it is 
a good principle of corporate governance to establish 
a remuneration policy which aligns with the Company’s 
purpose, strategy and culture. The Company is 
committed to being transparent and demonstrating good 
governance so the remuneration policy is presented within 
this Annual Report and will put to an advisory vote at the 
AGM. 
The Remuneration Committee is committed to structuring 
the remuneration packages of Executive Directors and 
senior management that are competitive and enable the 
Group to attract, retain and motivate talented people that 
can develop and execute the Group’s strategy. To promote 
the long-term success of the Company, the Executive 
Directors incentive benefits are performance based and 
earned only subject to the satisfaction of performance 
conditions. These performance conditions are aligned 
with the interests of the shareholders. 
The Committee remains sympathetic to the increased 
cost of living our employees are under but recognises the 
pay decisions we take needs to reflect the current and 
future needs of the business. In determining pay awards, 
consideration was given to financial sustainability, 
enabling the business to produce the returns it needs 
for further investment whilst ensuring Filtronic remains 
an attractive proposition to retain and attract the talent 
needed to deliver our business strategy. Therefore, we 
undertook an external benchmarking exercise, using 
third-party experts to compare remuneration packages 
we offer against similar businesses in terms of size and 
nature. This resulted in standard salary increases being 
awarded to the Executive Directors and key management 
of 5%.
The ’Our People’ section of this Annual Report and 
Accounts offers some greater insight into some of the 
additional benefits our employees enjoy as well as some 
of the access they get to third-party services for support 
with their health and wellbeing.

Governance report

www.filtronic.com  Stock Code: FTC
The Committee reviewed the outcomes for the FY2024 
annual incentive plan with the targets being met, and 
exceeded, in the year resulting in a full payment of the 
bonus scheme. 
The Committee also considered the performance-
related bonus plan to be implemented in FY2025, to 
ensure it aligned with the interests of shareholders. As the 
Company executes on its growth plans it was concluded 
that the revenue-based metric for the incentive scheme 
remains the best metric to assess performance against 
the scheme. The incentive for FY2025 will be awarded for 
achieving stretching targets against the FY2025 strategic 
business plan. The Committee is confident this will drive 
the right behaviours in the organisation to deliver long-
term shareholder value and ultimately increased revenue 
will lead to improved levels of profit. 
To support the long-range strategic plans and further 
align the interests of the Executive Directors and key 
management with shareholders, the Committee consulted 
with our major shareholders in the year in relation to 
the Employee Share Option Plan (“ESOP”) scheme and 
performance conditions. The scheme was restructured, 
with the new performance conditions, during the year 
to increase the headroom available to grant options 
to participants, including both the CEO and CFO, that 
incentive the right behaviours and align the outcomes with 
those of the shareholders.
The main activities of the Committee in FY2024 are set 
out in the table. I hope you find this report gives a clear 
account of the Committee’s approach and remuneration 
outcomes for the year. We are committed to maintaining 
an open dialogue with shareholders with regards to 
remuneration and would welcome any comments or 
concerns, relating to this report, that shareholders may 
have.

Directors’ remuneration policy
The objective of the Directors’ remuneration policy is to 
attract, retain and incentivise a high calibre of Executive 
Director, Senior Management and Non-Executive 
Directors who can direct the business and deliver the 
Group’s core objective of growth in shareholder value, by 
building a business that is capable of delivering long-term, 
sustainable growth.
The Board has overall responsibility for the remuneration 
policy but delegates the operation of it to the 
Remuneration Committee (“the Committee”) which 
is also responsible for ensuring our reward structure 
remains both competitive in our market and aligned with 
the interests of shareholders.  It has spent a significant 
amount of time assessing the policy to ensure it aligns 
the interests of the Executive Directors and Senior 
Management with the Group’s business strategy, growth 
ambition, culture and creation of long-term shareholder 
value. It is structured in compliance with Principle 9 of the 
QCA Code and ensures that appropriate incentives are in 
place to motivate and encourage enhanced performance, 
with rewards for contribution to the success of the Group 
being given in a fair and responsible manner. It supports 
and reinforces the desired corporate culture and aims to 
promote the right behaviours and decision making within 
the organisation.
Executive Directors and Senior Management
Pay structures for the Executive Directors and Senior 
Management have been implemented to be attractive to 
attract and retain whilst being aligned with shareholders’ 
interests. To achieve this objective, remuneration 
packages are awarded with elements of fixed and 
variable pay with share incentives structured to help 
Executive Directors and Senior Management build and 
hold a meaningful shareholding in the company.
The table below summarises the key components 
of remuneration for Executive Directors and senior 
management:
Base Salary
To reflect the individual’s 
skills and experience, 
providing a competitive 
base reward to recruit 
and retain people of the 
calibre needed to develop 
and deliver the Company’s 
strategy.
Base salaries are normally 
reviewed on an annual 
basis with any changes 
effective from 1 June.
Benefits
While there is no maximum 
salary, any increase will 
typically be in line with 
those awarded to the wider 
employee population.
The Remuneration 
Committee retains 
discretion to make 
exceptional salary increases 
in circumstances that it 
considers appropriate, for 
example:
i)	 where the individual 
has been promoted or 
gains a clear increase in 
responsibility.
ii)	 aligning pay with a 
market competitive rate.
iii)	 There is a material 
change in the size 
or complexity of the 
business.
Base salary levels 
and corresponding 
increases are based on 
individual experience, 
skills and business 
performance along with 
competitiveness against 
similar companies.

Bonus
To provide an incentive to 
deliver short-term stretching 
financial performance and 
growth targets.
Targets (financial and 
non-financial) are set 
and reviewed by the 
Committee annually.
Actual bonus payable 
is determined by the 
Committee after the 
financial year-end, based 
on performance against 
these targets
All employee bonuses 
are subject to malus and 
clawback provisions.
The bonus target is 75% of 
base salary in the case of 
the CEO and 50% of the 
base salary in the case of 
the CFO.
Under the financial element 
of the annual bonus, 
threshold performance 
must be exceeded 
before any annual bonus 
becomes payable. The 
percentage payout then 
increases according to 
the level of achievement 
against targets. Bonuses 
start accruing from a 
minimum threshold at 20% 
to the maximum amount 
payable of 150% of bonus 
target for exceptional 
outperformance.
The performance

Share 
Option Plan 
(“ESOP”)
To drive and incentivise

promote share ownership by 
the Executive Directors.
The exercise price of the 
share option is generally 
set at the market price 
on the date of the grant 
other than in exceptional 
circumstances. 
Vesting of the option 
is conditional on 
achievement of pre-
defined performance 
conditions, which the 
Committee considers to be 
appropriately stretching, 
and are measured over 
multiple financial periods. 
The Committee retains 
discretion to adjust the 
choice of performance 
measures to ensure they 
continue to be linked to 
the delivery of the Group’s 
strategy.
The Committee has 
full discretion as to the 
participants of the scheme 
and the number of options 
granted to each participant.
Awards vest based on 
the achievement of 
performance measures. 
The performance criteria 
are financial and include 
measures such as share 
price growth and adjusted 
EBITDA.
The Committee has 
discretion to adjust 
outcomes to ensure that 
payments accurately 
reflect underlying business 
performance over the 
period.

Notes to the policy table
Performance measures and targets
It is the Board’s intention to reward success. Therefore, the 
aim of the variable pay structure is to reward Executive 
Directors and Senior Management over and above base 
salary for the achievement of business objectives.
Performance targets are set to be stretching but 
achievable, with regard to the particular strategic 
priorities in a given year. The Committee retains the ability 
to adjust performance measures or targets if events 
occur (such as a change in Group strategy, a material 
acquisition or a change in prevailing market conditions) 
which cause the Committee to determine that measures 
are no longer appropriate and that an amendment is 
required so that they achieve their original purpose. 
Annual bonus
The bonus criteria are selected annually to reflect the 
Group’s main KPIs for the year and are designed to 
encourage continuous performance improvement for the 
Group. 
Group financial performance targets relating to the bonus 
plan are set with reference to the Group’s annual budget, 
which is reviewed and signed off by the Board prior to the 
start of each financial year.
Share schemes
The Committee has determined that the performance 
metrics for the recently announced ESOP scheme are 
share price growth and adjusted EBITDA performance 
over three financial periods to align business performance 
with the interests of the shareholders. Minimum and upper 
targets are set for achievement where vesting will only 
materialise if the lower target is met after the three years 
otherwise the share option will lapse. On achieving the 
minimum threshold, the ESOP vests at 50% of the total 
options granted and continues to vest on a straight-line 
basis until the upper target is achieved, at which point the 
maximum ESOP potential will vest.
Limit on sale of share option
To promote share ownership of Executive Directors and 
Senior Management there is a restriction on the number 
of shares that can be sold in any six-month period to a 
maximum of 1% the total share capital of the Company.
Remuneration policy for other employees
The approach to annual salary reviews is consistent 
across the Group, with consideration given to individual 
performance, skills, experience, responsibility, group 
performance, market conditions and salaries paid by 
similar companies. Pension participation is open to all 
employees and those enrolled receive life insurance and 
income protection (long term incapacity benefit). UK 
employees are also invited to join the SAYE plan on the 
same terms as the Executive Directors.
Depending upon role and seniority, some employees may 
also benefit from private healthcare and inclusion in the 
Filtronic Annual Bonus Scheme. The level of participation 
in all bonus and ESOP schemes is determined by the 
Board via the Remuneration Committee in consideration 
of role, responsibility and individual performance 
contribution.
Consideration of AIM market practice
The Board aims to keep reward packages and policy 
in line with AIM market norms and will take soundings 
from time to time with external advisors to take account 
of changing governance requirements and tax policy in 
respect of scheme rules. 
Consideration of shareholders’ views  
The Committee considers feedback received from all 
shareholders and seeks engagement to consult with 
major shareholders on key remuneration issues. The

Committee engages proactively with shareholders and 
ensures that they are consulted in advance where there 
are any material changes to the remuneration policy or 
elements of it. During FY2024, a consultation exercise was 
undertaken with major shareholders to seek feedback on 
the proposed changes to increase the number of options 
that could be granted to the Executive Directors and 
Senior Management.
Recruitment remuneration policy
The Committee recognises the importance of attracting 
the best talent available to the Company to deliver 
company strategy and long-term shareholder value. 
The Company will, therefore, on recruitment or 
internal promotion, to Executive Director or Senior 
Management apply the remuneration policy in full. This 
includes making use of any, or all of the components of 
remuneration set out in the table above. The Committee 
retains discretionary authority to set first year annual 
bonus performance targets for new recruits different 
to those for the other participants, in order to reflect a 
commencement period after business plans have been 
set and to also offer at commencement the immediate 
participation in the ESOP scheme.
In determining appropriate remuneration for a new 
Executive Director or Senior Manager, the Committee will 
take into consideration all relevant factors including the 
quantum, nature of remuneration and jurisdiction from 
which the candidate was recruited to ensure that the pay 
arrangements are in the best interests of the Group and its 
shareholders.
The Committee may include additional elements of pay 
which it considers appropriate in circumstances which 
may include: 
•	 Interim appointments; 
•	 Non-Executive Directors taking on an executive 
function on a short-term basis; and
•	 Where the timing of the recruitment means that it 
would be inappropriate to provide a bonus or ESOP 
opportunity for the year, in which case the quantum in 
respect of the opportunity for the year of recruitment 
may be transferred to the subsequent year in order that 
reward is provided on a fair and appropriate basis.
However, the Committee’s discretion is not unlimited. 
As noted above, salary, pension and benefits will be 
provided in line with the existing policy. The Committee 
may alter the performance measures and vesting periods 
of incentive remuneration and the deferral arrangements 
for the bonus or holding period for the ESOP to reflect the 
circumstances of the recruitment. The rationale for any 
exercise of this discretion will be explained in the following 
year’s remuneration report. 
In addition to the above elements of remuneration, the 
Committee may consider it appropriate to grant an 
award under a different structure in order to facilitate the 
recruitment of an individual, to replace remuneration, 
benefits and/or incentive arrangements forfeited on 
leaving a previous employer.
External appointments
It is the Board’s policy to allow each Executive Director 
to take up one non-executive position on the board of 
another company, subject to the prior approval of the 
Filtronic Board. Any fee earned in relation to outside 
appointments is retained by the Executive Director. No 
such positions were taken by Richard Gibbs nor Michael 
Tyerman and so no such fees were paid during the current 
financial year. Nat Edington currently has two Non-
Executive roles that he held prior to joining the Company 
but this will reduce to one in line with this remuneration 
policy by the end of the H1 FY2025.

Fees
To attract and retain high 
calibre individuals who have 
the experience to conduct 
both the statutory duties of 
a director, as well as advise 
on company strategy and 
oversee its implementation.
Fee reviews are conducted 
annually at the same 
time as the Executive 
Directors on 1 June 
of each financial year 
and consider economic 
conditions, market levels 
and the time commitment 
and contribution of each 
individual as well as the 
affordability for the 
Company.
Fees are payable entirely 
in cash. 
Neither the Chairman 
nor the Non-Executive 
Directors are permitted 
to participate in the 
Company’s performance-
based incentive plans.
Increases to fee levels will 
typically be in line with 
market levels of inflation. 
In exceptional 
circumstances (eg. material 
misalignment with the 
market or a change in the 
complexity, responsibility or 
time commitment required 
to fulfil the role of Non-
Executive Director) the 
Board retains the discretion 
to make appropriate 
adjustments to fee levels to 
ensure they remain market 
competitive and fair to the 
Director.
Non-Executive Directors 
receive an additional 
fee for Chairing a board 
committee.

Exit payments
When determining any loss of office payment for a 
departing Executive Director or Senior Manager the 
Committee will ensure that a consistent approach is 
adopted so that there is no reward for poor performance 
and the liabilities of the Group are minimised where 
appropriate. 
The underlying principle to be applied is that payment to 
an individual shall be limited to their contractual 
obligations and to honour any pre-established 
commitments with the exception that, for “good leavers” 
the committee will retain discretionary authority over the 
grant of pro-rata annual bonus, SAYE and ESOP awards.
No severance payment shall be made to any employee 
who is dismissed for serious breach of contract, serious 
misconduct or any acts or omissions that bring the 
company into disrepute.

Treatment of awards
“Good leaver” including

remuneration committee decides otherwise. In 
the event of the death of a participant during the 
performance period, the award would vest in full.
Not applicable.

The directors present their report together with the 
audited consolidated financial statements for the year 
ended 31 May 2024. 
Going concern
The Group’s business, and the factors likely to affect its 
future development, performance and position are set out 
in the Strategic report.
The revenue, trading results and cash flows are explained 
in the Financial review on page 18. 
After a review of forecasts including projections of 
profitability and cash flows for the year to 31 May 2025  
and a further two years, the directors believe that the 
Group has adequate resources to continue to operate 
for the foreseeable future and that it is therefore 
appropriate  to continue to adopt the going concern basis 
of accounting in the preparation of the consolidated and 
Company financial statements. The basis of preparation, 
in note 1, provides more detail on this. 
Directors and their interests
The directors of the Company during the year, and up to 
the date of signing this report, were as follows:
Executive Directors

Nat Edington will stand for election at the Annual 
General Meeting (“AGM”), being the first one since he was

will stand for re-election annually starting at the 2024 
AGM.

liability insurance on behalf of its directors and officers in

Research and development expenditure
Research and development costs in the year are set out in 
the Financial Review on page 18.
Treasury policy
The Group’s treasury policy aims to manage the Group’s 
financial risk and to minimise the adverse effects of 
fluctuations in the financial markets on the value of 
the Group’s financial assets and liabilities, on reported 
profitability and on the cash flows of the Group. Note 35 
sets out the particular risks to which the Group is exposed, 
and how these are managed.
Significant events and future developments 
There have been no significant events since the reporting 
date. The Group’s future developments are disclosed in the 
Strategic Report on pages 3 to 41.
Share capital
The Company’s share capital consists of 0.1p ordinary 
shares. The rights and obligations attached to each share 
are equal. Each share carries the right to one vote at the 
Annual General Meeting of the Company and carries no 
right to fixed income. There are no limitations on holding 
or transfer of the shares. The Board has no powers to 
issue or buy back the Company’s shares, other than those 
approved by the shareholders at the Annual General 
Meeting held in October 2023.
Substantial shareholdings
Up to 31 May 2024, the Company had been notified, 
by shareholders, in accordance with chapter 5 of the 
disclosure and transparency rules, of the voting rights 
they held as shareholders of the Company. An analysis 
of shareholders as at 31 May 2024 (as disclosed by 
shareholders via TR1) is set out in the table below. As at 
31 May 2024, the Company had issued share capital of 
218,033,210 ordinary shares of 0.1p each.

County Durham,  
TS21 3FD. 
Full details of the business to be transacted at the meeting 
will be set out in the notice of the Annual General Meeting.
Renewal of authority to purchase the 
Company’s shares
Last year, a resolution was passed at the Annual General 
Meeting to give the Company the authority to purchase 
its own Ordinary shares on the Stock Exchange. This 
authority expires eighteen months from the passing of 
the resolution. To avoid this authority expiring during the 
next year and the need to call an extraordinary general 
meeting to renew the authority, a resolution to renew the 
authority will be requested at the Annual General Meeting 
Under the terms of the resolution to be proposed at 
the Annual General Meeting, the maximum number of 
shares which may be purchased is 10% of the issued 
ordinary share capital of the Company. The minimum 
price payable by the Company for its ordinary shares 
will be 0.1p and the maximum price will be determined 
by reference to current market prices. The authority will 
automatically expire after a period of eighteen months 
from the passing of the resolution unless renewed.
It is not the Directors’ current intention to exercise the 
power to purchase the Company’s ordinary shares, but 
they believe that under certain circumstances it would be 
in the Company’s best interests to do so.
The Directors consider the resolutions to be proposed at 
the meeting are in the best interests of the Company and 
its shareholders. Therefore, they unanimously recommend 
that all shareholders vote in favour of the resolution at the 
Annual General Meeting as they intend to do in respect of 
their beneficial holdings.
Statement of directors’ responsibilities in 
respect of the financial statements
The directors are responsible for preparing the Annual 
Report and Accounts and the financial statements in 
accordance with applicable law and regulation.
Company law requires the directors to prepare financial 
statements for each financial year. Under that law the 
directors have prepared the group and the company 
financial statements in accordance with UK-adopted 
international accounting standards.
Under company law, directors must not approve the 
financial statements unless they are satisfied that they 
give a true and fair view of the state of affairs of the group 
and company and of the profit or loss of the group for that 
period. In preparing the financial statements, the directors 
are required to:
•	 select suitable accounting policies and then apply them 
consistently;
•	 state whether applicable UK-adopted international 
accounting standards have been followed, subject to 
any material departures disclosed and explained in the 
financial statements;
•	 make judgements and accounting estimates that are 
reasonable and prudent; and
•	 prepare the financial statements on the going concern 
basis unless it is inappropriate to presume that the 
group and company will continue in business.
The directors are 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 keeping adequate 
accounting records that are sufficient to show and explain 
the group’s and company’s transactions and disclose with 
reasonable accuracy at any time the financial position of 
the group and company and enable them to ensure that 
the financial statements comply with the Companies Act 
2006.
The directors are responsible for the maintenance 
and integrity of the company’s website. Legislation in 
the United Kingdom governing the preparation and 
dissemination of financial statements may differ from 
legislation in other jurisdictions.
Directors’ confirmations
In the case of each director in office at the date the 
directors’ report is approved:
•	 so far as the director is aware, there is no relevant 
audit information of which the Group’s and Company’s 
auditors are unaware; and
•	 they have taken all the steps that they ought to have 
taken as a director in order to make themselves aware 
of any relevant audit information and to establish that 
the Group’s and Company’s auditors are aware of that 
information

Independent auditors’ report 
to the members of Filtronic plc
Opinion
We have audited the financial statements of Filtronic plc (the “Company”) and its subsidiaries (the “Group”) for the 
year ended 31 May 2024, which comprise:
•	 the Consolidated income statement and statement of comprehensive income for the year ended 31 May 2024;
•	 the Consolidated and Company balance sheets as at 31 May 2024;
•	 the Consolidated and Company statements of changes in equity for the year then ended;
•	 the Consolidated and Company cash flow statements for the year then ended; and
•	 the notes to the financial statements, including accounting policies.
The financial reporting framework that has been applied in the preparation of the financial statements is 
applicable law and UK-adopted international accounting standards.
In our opinion the financial statements:
•	 give a true and fair view of the state of the Group’s and of the Parent Company’s affairs as at 31 May 2024 and 
of the Group’s profit for the period then ended;
•	 have been properly prepared in accordance with UK-adopted international accounting standards; 
•	 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 the 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.
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’s and 
Company’s ability to continue to adopt the going concern basis of accounting included:
•	 Assessing management’s base case and severe but plausible downside cash flow forecasts, including challenging 
management on the key assumptions underpinning the models, which included sales forecasts, margin performance 
and working capital assumptions;
•	 Considering the mitigating actions included in the severe but plausible downside scenario to consider whether they 
reflected actions within management’s control, as well as any costs associated with implementing these mitigating 
actions;
•	 Reviewing historic trading results and ‘looking back’ to compare them with management’s original budget for the 
relevant period, to consider management’s historical forecasting accuracy;
•	 Testing the mathematical accuracy and integrity of management’s model;
•	 Performing additional sensitivity analysis of management’s severe but plausible case; and
•	 Considering the disclosures provided in the financial statements with respect to going concern for consistency with the 
models that were subject to audit.
Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions 
that, individually or collectively, may cast significant doubt on the Group’s and 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.
Overview of our audit approach
Materiality
In planning and performing our audit we applied the concept of materiality. An item is considered material if it could 
reasonably be expected to change the economic decisions of a user of the financial statements. We used the concept of 
materiality to both focus our testing and to evaluate the impact of misstatements identified.
Based on our professional judgement, we determined overall materiality for the Group financial statements as a whole to 
be £215,000, based on 0.85% percent of Group turnover. Materiality for the Company financial statements as a whole 
was set at £30,000 based on 0.65% of total assets.
We use a different level of materiality (‘performance materiality’) to determine the extent of our testing for the audit of 
the financial statements.  Performance materiality is set based on the audit materiality as adjusted for the judgements 

Governance report
67
www.filtronic.com  Stock Code: FTC
made as to the entity risk and our evaluation of the specific risk of each audit area having regard to the internal control 
environment. This is set at £150,500 for the group and £21,000 for the parent.
Where considered appropriate performance materiality may be reduced to a lower level, such as, for related party 
transactions and directors’ remuneration.
We agreed with the Audit and Risk Committee to report to it all identified errors in excess of £8,750. Errors below that 
threshold would also be reported to it if, in our opinion as auditor, disclosure was required on qualitative grounds.
Overview of the scope of our audit
Our group audit was scoped by obtaining an understanding of the Group and its environment, including Group-wide 
controls, and assessing the risks of material misstatements at the Group level. For the three significant components we 
identified, which are Filtronic plc, Filtronic Broadband Limited and Filtronic Wireless Inc., we performed a full scope audit 
of the complete financial information to component materiality. For the remaining components, we performed analytical 
reviews and other audit procedures on specific accounts within that component that we considered had the potential for 
the greatest impact on the significant accounts in the financial statements, either because of the size of these accounts or 
their risk profile.
The group audit team conducted the audit of all components of the business and no component auditors were used 
during the audit process.
Key Audit Matters
Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the 
financial statements of the current period and include the most significant assessed risks of material misstatement 
(whether or not due to fraud) that we identified. These matters included those 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.
This is not a complete list of all risks identified by our audit.
Our audit procedures in relation to these matters were designed in the context of our audit opinion as a whole. They were 
not designed to enable us to express an opinion on these matters individually and we express no such opinion.
Key audit matter
Carrying value of goodwill (Group)
 
 
Refer to page 77 (Key accounting matters) and note 14 to 
the financial statements.
The goodwill balance is £974,000. We focused on this 
area due to the material goodwill balance held on the 
consolidated balance sheet and the estimates and 
judgements required to determine recoverable amount.
How our audit addressed the key audit matter
We considered the carrying value of goodwill and non- 
current assets by reference to management’s value in use 
model, which was based on discounted cash flows.
We considered the carrying value of goodwill and non- 
current assets by reference to management’s value in use 
model, which was based on discounted cash flows.
We obtained and understanding of the systems and 
controls in relation to Goodwill and carried out a 
walkthrough to confirm the design and implementation of 
these controls.
We assessed management’s determination of CGUs 
against technical guidance and considered whether 
the impairment assessment was performed at the 
appropriate level, considering management’s own internal 
reporting for monitoring of goodwill.  We tested the inputs 
to the model to Board approved budgets, which included 
short and long-term growth rates. We also tested the 
integrity of the model and its mathematical accuracy.
We determined that the calculations were most sensitive 
to growth assumptions and calculated the degree to 
which these assumptions would need to move before 
any impairment was required. We assessed the short- 
term growth rate assumptions against purchase orders 
and contracts, along with available market data for the 
telecommunications infrastructure sector.

Key audit matter
Carrying value of goodwill (Group) (continued)
 
 
 
 
 
 
Capitalisation and carrying value of development costs 
Within the intangible assets held by the group (see note 
14 of the consolidated financial statements), there are 
material balances relating to internally generated, 
capitalised development costs. The process of correctly 
identifying and capitalising this development expenditure 
in the year requires the critical application of judgement 
by management, and as such is considered a key audit 
matter.
In carrying out impairment assessments there is a risk that 
the key assumptions such as revenue growth, terminal 
growth rate, variability of costs and discount rates used in 
the impairment review model are not appropriate.  
How our audit addressed the key audit matter
 
We also read the disclosures provided in the financial 
statements regarding goodwill impairment testing, 
and the associated disclosure of the critical accounting 
estimates, and found these to be appropriate.
Based on the procedures we performed we were able to 
obtain sufficient audit evidence in respect of the carrying 
value of goodwill and non-current assets.
 
We have reviewed and challenged management’s 
assessment of whether additions met the criteria 
for capitalisation and whether brought forward 
developments continued to meet the criteria for 
capitalisation.  We corroborated a sample of the amounts 
capitalised in the year to supporting documentation 
including invoices for external costs and an approximate 
evaluation of internal resource/time capitalised. We 
reviewed management’s assessment of capitalisation 
criteria in order to conclude if this was appropriate 
in accordance with IAS38.We have gained an 
understanding of the group’s process and controls around 
the capitalisation and carrying value of development 
costs.
We obtained and reviewed management’s assessment of 
indicators of impairment; management’s key estimates 
are set out within the disclosure of critical accounting 
estimates and judgements on page 81. 
We reviewed the appropriateness of the amortisation 
periods in the context of the continuing development of 
technologies which may give rise to obsolescence, and the 
expected recovery of the assets against future sales.
Other information
The directors are responsible for the other information contained within the annual report. The other information 
comprises the information included in the annual report, other than the financial statements and our auditor’s report 
thereon. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise 
explicitly stated in our report, we do not express any form of assurance conclusion thereon.
Our responsibility is to read the other information and, in doing so, consider whether the other information is materially 
inconsistent with the financial statements or our knowledge obtained in the audit or otherwise appears to be materially 
misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine 
whether 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.
Opinion on other matter prescribed by the Companies Act 2006
In our opinion based on the work undertaken in the course of our audit 
•	 the information given in the strategic report and the directors’ report for the financial year for which the financial 
statements are prepared is consistent with the financial statements; and
•	 the strategic report and the directors’ report have been prepared in accordance with applicable legal requirements.
Matters on which we are required to report by exception
In light of the knowledge and understanding of the Group and the 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 where 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

Governance report
69
www.filtronic.com  Stock Code: FTC
•	 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 the directors for the financial statements
As explained more fully in the directors’ responsibilities statement set out on page 65, 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 Parent Company’s 
ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going 
concern basis of accounting unless the directors either intend to liquidate the Group or the Parent Company or to cease 
operations, or have no realistic alternative but to do so.
Auditor’s responsibilities for the audit of the financial statements
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from 
material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. 
Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with 
ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are 
considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic 
decisions of users taken on the basis of these financial statements.
Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line 
with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The 
extent to which our procedures are capable of detecting irregularities, including fraud is detailed below:
We obtained an understanding of the legal and regulatory frameworks within which the Group and Company operates. 
We also considered and obtained an understanding of the UK legal and regulatory framework which we considered in 
this context were the Companies Act 2006 and taxation legislation.
We identified the greatest risk of material impact on the financial statements from irregularities, including fraud, to be the 
override of controls by management, misstatement of revenue and misstatement of carrying value of intangible assets 
including goodwill. Our audit procedures to respond to these risks included enquiries of management about their own 
identification and assessment of the risks of irregularities, sample testing on the posting of journals. We also reviewed and 
challenged accounting estimates and assumptions used by management for the impairment assessment of goodwill and 
intangible assets (ee Key Audit Matters above) and recognition of contract income, in order to verify that the calculations 
and models were reasonable and free of biases. 
Owing to the inherent limitations of an audit, there is an unavoidable risk that we may not have detected some 
material misstatements in the financial statements, even though we have properly planned and performed our audit in 
accordance with auditing standards. We are not responsible for preventing non-compliance and cannot be expected to 
detect noncompliance with all laws and regulations.
These inherent limitations are particularly significant in the case of misstatement resulting from fraud as this may involve 
sophisticated schemes designed to avoid detection, including deliberate failure to record transactions, collusion or the 
provision of intentional misrepresentations. A further description of our responsibilities is available on the Financial 
Reporting Council’s website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report.
Use of our report
This report is made solely to the company’s members, as a body, in accordance with Chapter 3 of Part 16 of the 
Companies Act 2006. Our audit work has been undertaken so that we might state to the company’s members those 
matters we are required to state to them in an auditor’s report and for no other purpose. To the fullest extent permitted 
by law, we do not accept or assume responsibility to anyone other than the company and the company’s members as a 
body, for our audit work, for this report, or for the opinions we have formed.

Material accounting policies
Reporting entity
Filtronic plc is a public company limited by shares registered in England and Wales, domiciled in the United 
Kingdom, and listed on AIM on the London Stock Exchange. The principal activity of the Company is design, 
development and manufacture of high performance Radio Frequency (“RF”) technology.
Basis of preparation
The Company and consolidated financial statements for the year ended 31 May 2024 have been prepared in 
accordance with UK-adopted international accounting standards and with the requirements of the Companies Act 
2006 as applicable to companies reporting under those standards.
The financial statements have been prepared under the historical cost convention except for forward foreign 
exchange contracts that are accounted for on a fair value basis.
The accounting policies have been applied consistently throughout the Group.
Going concern
In accordance with corporate governance requirements and the statement of directors’ responsibilities, and 
as disclosed in the Directors’ Report, the directors have undertaken a review of forecasts and the Group’s cash 
requirements to consider whether it is appropriate that the Group continues to adopt the going concern assumption.
At 31 May 2024, the Group had cash at bank of £7.2m and access to undrawn invoice discounting facilities of 
£3.0m and $4.0m in the UK and US respectively. Details of these facilities can be found in note 35.
As referred to in the Strategic report, the Board recognises the uncertain economic and political environment that 
the world faces and has reviewed the business outlook to reflect this uncertainty. Cash flow forecasts have been 
prepared to model various scenarios over a three-year period based on the Group’s financial and trading position, 
principal risks and uncertainties and strategic plans. 
A downside scenario was modelled, to stress-test the business forecast, where programme curtailment and/or 
delays may adversely affect forward-looking demand to levels lower than those initially modelled in the base case 
scenario including reduced demand from a major customer. 
A severe but plausible scenario was also modelled that took the downside scenario and removed a significant 
contract win that the Group expected to convert from the outlook period. 
The scenarios modelled including the severe but plausible model, demonstrate the Group has adequate cash for the 
next twelve months from the date of the approval of the accounts. 
The directors are confident that the Group and company will have sufficient funds to continue to meet their liabilities 
as they fall due for at least 12 months from the date of approval of the financial statements and therefore continue 
to adopt the going concern basis to prepare the financial statements.
Basis of consolidation and foreign currency translation
The financial statements consolidate the income statements, statement of financial position and cash flow 
statements of the Company and all of its subsidiaries.
Subsidiaries are entities controlled by the Group. The Group controls an entity when it is exposed to, or has rights 
to, variable returns from its involvement with the entity and has the ability to affect those returns through its power 
over the entity. This includes the power to govern the financial and operating policies. In assessing control, the Group 
takes into consideration potential voting rights. Subsidiaries are consolidated from the date on which control is 
transferred to the Group, and are not consolidated from the date that control ceases. Intragroup transactions and 
balances are eliminated on consolidation.
On consolidation, the financial statements of subsidiaries with a functional currency other than sterling are 
translated into sterling as follows:
•	 The assets and liabilities in their statement of financial position plus any goodwill are translated at the rate of 
exchange ruling at the statement of financial position date; and
•	 The income statements and cash flow statements are translated at the average rate of exchange each month 
in the financial year, which approximates the rate of exchange ruling at the date of the transactions. Any 
exchange difference is included in the Consolidated statement of comprehensive income.
Currency translation movements arising on the translation of the investments in foreign subsidiaries are recognised 
in the translation reserve, which is a separate component of equity.
The functional currency of each Group company is the currency of the primary economic environment in which 
the Group company operates. The financial statements are presented in sterling which is the functional and 
presentational currency of the Company.
Notes to the consolidated financial statements
for the year ended 31 May 2024

Filtronic plc Annual Report and Accounts 2024

Material accounting policies (continued) 
Transactions denominated in foreign currencies are translated into the functional currency of each Group company 
at the exchange rate ruling at the date of the transaction. Monetary assets and liabilities denominated in foreign 
currencies are translated into the functional currency at the rate of exchange ruling at the statement of financial 
position date.
Foreign exchange gains and losses arising on the settlement of such transactions and translation of monetary assets 
and liabilities are recognised in the income statement.
Revenue
IFRS 15 establishes principles for determining when and how revenue arising from contracts with customers should 
be recognised. Filtronic recognises revenue when it transfers goods or services to a customer with an amount of 
consideration expected to be received in exchange for fulfilling the performance obligation with the customer.
The Group reviews all income streams against the requirements of IFRS 15. Management undertakes an assessment 
of all contracts and revenue streams across the business using the five-step approach specified by IFRS 15: 
1)	Identify the contract(s) with the customer;
2)	Identify the performance obligations in the contract; 
3)	Determine the transaction price; 
4)	Allocate the transaction price to the performance obligations in the contract;  and
5)	Recognise revenue when (or as) a performance obligation is satisfied.
In determining the appropriate method of recognising revenue, management is required to make judgements 
as to whether performance obligations are satisfied over a period of time or at a point in time. For performance 
obligations that are satisfied over a period of time, judgements are made as to whether the output method or 
the input method is more appropriate to measure progress towards complete satisfaction of the performance 
obligation. If performance obligations are not satisfied over time, the Group recognises revenue at a point in time.
Revenue is measured at the fair value of consideration received or receivable for goods and services provided 
or performed in the normal course of business net of value added tax or sales tax. The nature of our revenue is 
disclosed below:
Revenue relating to finished goods product
Sales of finished goods product to customers are recognised when control of the product has transferred to the 
customer and the performance obligation has been satisfied at a point in time. This is usually when title passes, 
either on shipment or on receipt of goods depending on the delivery terms of the customer contract. The transaction 
price is specified in the customer contract. 
Revenue relating to non-recurring engineering (“NRE”)
NRE comprises contracts to provide engineering services, such as the design and development of a product, 
funded by the customer. The transaction price of the contract is known from inception of the contract. Each contract 
is reviewed to identify the number of distinct performance obligations and the transaction price is assigned 
accordingly, usually by the value of work performed on an output method basis; outputs are typically milestones 
within the development such as design reviews, reports and prototype products. Based on the performance of the 
obligations in the contract being met, revenue is recognised over time. If relevant, an expected loss on a contract is 
recognised immediately in the income statement.
Current tax
Current tax is the expected tax payable or receivable on the taxable income or loss for the year, using rates enacted 
or substantively enacted at the reporting date, and any adjustment to tax payable in respect of previous years.
Goodwill
Goodwill that arises upon the acquisition of subsidiaries is included in intangible assets is measured at cost less 
accumulated impairment losses. Goodwill, which is allocated to cash-generating units, is tested for impairment 
at least annually and when there is an indication of impairment. The goodwill carrying value is written down to its 
recoverable amount. An impairment loss recognised for goodwill is not reversed in a subsequent period.
On disposal of a subsidiary, the attributable amount of goodwill is included in the determination of the profit or loss 
on disposal.

Internally-generated intangible assets
All research costs are expensed as incurred.
Development costs chargeable to the customer are recognised as an expense in the same period as the associated 
customer revenue.
Development costs incurred on projects requiring product qualification tests to satisfy customer specifications 
are generally expensed as incurred, reflecting the technical risks associated with meeting the resultant product 
qualification test. 
Development costs incurred on projects are capitalised where: 
	
1)  The technical feasibility can be tested against relevant milestones;
	
2)  The probable revenue stream foreseen over the life of the resulting product can support the development; and 
	
3)  Sufficient resources are available to complete the development. 
These capitalised costs are amortised on a straight-line basis over the expected life of the associated product. The 
estimated useful lives for the current and comparative periods are:
•	 Capitalised development costs	
1 to 6 years
Other intangible assets
Other intangible assets that are acquired by the Group and have finite useful lives are measured at cost less 
accumulated amortisation and accumulated impairment losses.
Amortisation is calculated over the cost of the asset less its residual value.
Amortisation is recognised in the income statement on a straight-line basis over the estimated useful lives of 
intangible assets, other than goodwill, from the date that they are available for use, since this most closely reflects 
the expected pattern of consumption of the future economic benefits embodied in the asset.
The estimated useful lives for the current and comparative periods are as follows:
•	 Software licence	
	
	
4 to 5 years
Amortisation methods, useful lives and residual values are reviewed at each financial year end and adjusted if 
appropriate.
Impairment charges
The carrying amounts of the Group’s non-financial assets, other than inventories and deferred tax assets, are 
reviewed at each reporting date to determine whether there is any indication of impairment. If any such indication 
exists, then the asset’s recoverable amount is estimated. For goodwill and intangible assets that have indefinite 
useful lives or that are not yet available for use, the recoverable amount is estimated each year at the same time. 
The recoverable amount of an asset or cash-generating unit is the greater of its value in use and its fair value less 
costs to sell. In assessing value in use, the estimated future cash flows are discounted to their present value using a 
pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to 
the asset. In assessing the fair value less cost to sell (“FVLCTS”), an estimated market multiple is determined and 
applied to the forecast EBITDA of the cash generating unit (“CGU”).
For the purposes of impairment testing, assets that cannot be tested individually are grouped together into the 
smallest group of assets that generates cash inflows from continuing use that are largely independent of the cash 
inflows of other assets or groups of assets (the “CGU”). For the purpose of goodwill impairment testing, CGUs to 
which goodwill has been allocated are aggregated so that the level at which impairment is tested reflects the lowest 
level at which goodwill is monitored for internal reporting purposes.
An impairment loss is recognised if the carrying amount of an asset or its CGU exceeds its estimated recoverable 
amount. Impairment losses are recognised in the income statement. Impairment losses recognised in respect of 
CGUs are allocated first to reduce the carrying amount of any goodwill allocated to the units, and then to reduce 
the carrying amounts of the other assets in the unit (group of units) on a pro rata basis. An impairment loss in respect 
of goodwill is not reversed. In respect of other assets, impairment losses recognised in prior periods are assessed 
at each reporting date for any indications that the loss has decreased or no longer exists. An impairment loss is 
reversed if there has been a change in the estimates used to determine the recoverable amount. An impairment loss 
is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have 
been determined, net of depreciation or amortisation, if no impairment loss had been recognised.

Right of use assets and lease liabilities
The Group assesses whether a contract is a lease at inception of the contract. The Group recognises a right of use 
asset and a corresponding lease liability with respect to all lease arrangements in which it is the lessee, except for  
short-term leases and leases of low value assets which includes the Group’s leased office equipment such as 
printers. For these leases, the Group recognises the lease payment as an operating expense on a straight-line basis 
over the term of the lease.
The lease is initially measured at the present value of the lease payments that are not paid at the commencement 
date, discounted using the interest rate implicit in the lease or the incremental borrowing rate. This is the rate when 
it is not possible to determine the interest rate in the lease and represents what we would have to pay for a loan of 
a similar item and term of repayment. The lease liability is subsequently increased by the interest cost on the lease 
and decreased by payments made. In the event of a change in future lease payments, the lease liability will be 
remeasured and the difference recognised in the right of use asset. 
The Group remeasures the lease liability and makes a corresponding adjustment to the right of use asset whenever 
there has been a lease payment change, the lease contract is modified or any other significant event.
The right of use asset is initially measured at cost , which comprises the initial amount of the lease liability adjusted 
for any lease payments made at or before the commencement date, and subsequently at cost less accumulated 
depreciation and impairment losses. The right of use asset is depreciated over the shorter of the period of the lease 
term and useful life of the underlying asset. Where there is reasonable certainty the Group will purchase the asset at 
the end of the lease, the asset is depreciated over the useful life. The depreciation starts at the commencement date 
of the lease.
Where property leases contain a break option the value of the lease liability and right of use asset recognised on the 
statement of financial position requires judgement to determine the lease term. The Group recognises the full term 
of the lease, ignoring the break option, as invariably the option will not be exercised.
Property, plant and equipment
Property, plant and equipment are stated at cost less accumulated depreciation and less any accumulated 
impairment losses.
Depreciation is provided on a straight-line basis over the estimated useful lives of the assets as follows:
•	 Fixtures and fittings 	
		
2 to 10 years
•	 Plant and equipment 	
		
3 to 10 years
•	 Computer hardware	
		
2 to 4 years
Property, plant and equipment are tested for impairment when there is an indication of impairment. If impaired, the 
carrying values of the assets are written down to their recoverable amounts.
The gain or loss arising on disposal or scrappage of an asset is determined as the difference between the sales 
proceeds and the carrying amount of the asset and is recognised in income.
Deferred taxation
Deferred tax is the tax expected to be payable or recoverable on differences between the carrying amounts of 
assets and liabilities in the Consolidated Statement of Financial Position and the corresponding tax bases used in 
the computation of taxable profit and is accounted for using the statement of financial position liability method. 
Deferred tax liabilities are generally recognised for all taxable temporary differences and deferred tax assets are 
recognised to the extent that it is probable that taxable profits will be available against which deductible temporary 
differences can be utilised. Such assets and liabilities are not recognised if the temporary difference arises from the 
initial recognition of goodwill or from the initial recognition (other than in a business combination) of other assets 
and liabilities in a transaction that affects neither the taxable profit nor the accounting profit; or if at the time of the 
transaction, they do not give rise to equal taxable and deductible temporary differences.
The carrying amount of deferred tax assets is reviewed at each statement of financial position date and reduced to 
the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset 
to be recovered.

Material accounting policies (continued)
Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the 
asset is realised based on tax laws and rates that have been enacted or substantively enacted at the statement of 
financial position date. Deferred tax is charged or credited in the income statement, except when 
	
•	 it relates to items charged or credited in other comprehensive income, in which case the deferred tax is  
	
also dealt with in other comprehensive income;
	
•	 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 and liabilities are offset when there is a legally enforceable right to set off current tax assets 
against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the 
Group intends to settle its current tax assets and liabilities on a net basis.
Inventories
Inventories are stated at the lower of cost and net realisable value. Net realisable value is the estimated selling price 
less estimated costs of completion and sale. Inventory, including work in progress, costs comprise direct materials 
only. Cost is stated in the consolidated statement of financial position at standard cost, revalued to actual cost, 
based on a first in-first out basis.
Provision is made for obsolete, slow moving or defective materials where appropriate. This is reviewed monthly.
Trade and other receivables
Trade and other receivables are amounts due from customers for goods and services performed in the ordinary 
course of business. They are initially recorded at the transaction price and thereafter measured at amortised cost 
using the effective interest method, less an allowance for expected credit losses.
Cash and cash equivalents
For the purpose of the cash flow statement and statement of financial position, cash and cash equivalents comprise 
cash at bank and short-term bank deposits with an original maturity of three months or less.
Warranty provision
A provision is recognised in the statement of financial position when there is a present legal or constructive 
obligation as a result of a past event, and it is probable that an outflow of resources will be required to settle the 
obligation and the amount can be reliably estimated. A warranty provision is recognised when products are sold 
based on historical warranty data. The level of warranty provision required is reviewed on a product-by-product 
basis and adjusted accordingly in light of actual experience.
Dilapidations and onerous leases
A provision for dilapidations and onerous leases is recognised in the statement of financial position on a lease-by-
lease basis and is based on the Group’s best estimates of the required cost to settle the relevant obligations.
Grants
Capital-based grants, when present, are included within deferred income in the statement of financial position and 
credited to the profit and loss account over the estimated useful economic lives of the assets to which they relate.
Grants that compensate the Group for expenses incurred are recognised in the profit or loss account as other 
operating income on a systematic basis in the same periods in which the expenses are recognised.
Financial liabilities
Financial liabilities comprise interest bearing borrowings and are initially recognised at fair value and subsequently 
measured at amortised cost with any net gains or losses, including any interest expense, recognised in profit or loss.
Share capital
Ordinary shares issued are classified as share capital in equity.
Dividends 
Interim dividends are recognised in equity in the financial year they are paid. Final dividends are recognised in 
equity in the financial year they are approved by shareholders.

Share-based payments
The Group operates equity settled share option schemes, under which share options are granted to certain 
employees. The fair value of the share options at the date of grant was calculated using an option pricing model, 
taking into account the terms and conditions applicable to the option grant. 
The total amount to be expensed is determined by reference to the fair value of the options granted: 
•	 including any market performance conditions (e.g. the entity’s share price); and
•	 excluding the impact of any non-market performance vesting conditions (e.g. profitability, sales growth 
targets).
The fair value of the number of share options expected to vest was expensed in the income statement on a straight-
line basis over the expected vesting period. At each reporting period, these vesting expectations were revised as 
appropriate. A credit is made to equity equal to the share-based payment charge in the financial year.
Defined contribution pension schemes 
Defined contribution pension schemes are operated for employees. Contributions are recognised as an expense in 
the income statement as incurred.
Forward currency contracts
Forward currency contracts are held at fair value. The gain or loss on re-measurement to fair value is recognised 
immediately in the consolidated income statement.
Accounting developments and new standards
At the date of authorisation of these financial statements, new and revised standards issued but not yet effective 
are set out below. It is anticipated the adoption of these standards and interpretations in future periods will have no 
material impact on the financial statements of the Group. These have not been adopted in the Group’s accounting 
policies.
•	 Amendments to IAS 1 ‘Classification of Liabilities as Current or Non-Current’;
•	 Amendments to IAS 7 Statement of Cash Flows and IFRS 7 Financial Instruments: Disclosure: Supplier Finance 
Arrangements.
•	 Amendments to IAS 21 The Effects of Changes in Foreign Exchange Rates: Lack of Exchangeability
•	 Amendments to IAS 1 ‘Non-Current Liabilities with Covenants’ and;
•	 Amendments to IFRS 16 ‘Lease liability in a sale and lease back’.
•	 Introduction of IFRS 18 ‘Presentation and disclosure in financial statements’.
The Group is assessing the impact of these new standards and the Group’s financial reporting will be presented in 
accordance with these standards from the relevant accounting period.

Accounting estimates and judgements
The preparation of the financial statements requires the use of accounting estimates and judgements, that affect 
the application of accounting policies, which are described in note 1,  and reported amounts of assets and liabilities, 
income and expenses. The directors are required to make accounting estimates and judgements which are 
continually evaluated. They are based on historical experience and other factors, including expectations and best 
estimates of the future, that are believed to be reasonable under the circumstances. Actual results may differ from 
the expected results.
Key sources of estimation uncertainty
The key estimates concerning the future, that have a significant effect on the financial statements are considered 
below:
Investments in subsidiaries - impairment
Investments in subsidiaries are tested for impairment by reference to their recoverable amount relative to their 
carrying value. In accordance with IAS 36, recoverable amount is determined as the higher of value in use (“VIU”), 
determined based on the expected cash generated by the CGU to which the investment relates and fair value less 
costs to sell (“FVLCTS”). Both models are subject to uncertainties surrounding the EBITDA and cash flow forecasts 
being used.
The sensitivity analysis in respect of the recoverable amount of investments in subsidiaries is presented in note 4 of 
the Company accounts.
Goodwill and other intangibles - impairment
Goodwill and other intangibles are tested for impairment by reference to the expected cash generated by the cash 
generating unit (“CGU”) or group of CGUs. This is deemed to be the best approximation of value, but is subject to 
the same uncertainties as the cash flow forecast being used. The forecasts comprise forecasts of revenue, material 
costs and overhead costs based on current and anticipated market conditions that have been considered and 
approved by the Board. Whilst the Group is able to manage most of its costs, significant elements of the revenue 
forecasts are inherently linked to global demand where uncertainty about both the timing and level of growth 
remains which is a key sensitivity.
Capitalised development costs - impairment
Intangible assets include development cost assets which have been reviewed for impairment as at the reporting 
date.
The recoverable amount of each technology development project has been determined based on value in use 
calculations, using cash flow projections in line with the expected useful economic life of each asset. The value in use 
calculations are based on management approved risk-adjusted cash flow forecasts for each project and have been 
discounted using a pre-tax discount rate of 16%.
The key assumptions used in the cash flow projections relate to revenue and gross profit margin for each technology 
and are based on assumptions about expected customer demand which is inherently linked to the global demand 
for the technology under development where the timing and level of demand is subject to uncertainty. The Group 
has carried out a sensitivity analysis on the impairment tests of each of these projects, using various reasonably 
possible scenarios and concluded there to be no impairment risk.
Deferred tax asset
The recognition of deferred tax assets relating to tax losses carried forward depends on forecasts of the future 
taxable profits of the Company and its subsidiaries. The Group has assessed the recoverability of its deferred 
tax assets by reference to Board approved budgets and cash flow forecasts. These forecasts require the use of 
estimates and judgements about the future performance of the Company and its subsidiaries using the current 
order book, forecasts and market knowledge.
Deferred tax assets have been recognised within Filtronic Broadband Limited in the UK and Filtronic Wireless Inc. 
in the USA so a change to forecast customer demand in either of these subsidiaries would impact on the amount of 
deferred tax asset recognised. A 10% forecast reduction in the profitability of these subsidiaries would see deferred 
tax asset recognition reduce by an additional £314,000.

Accounting estimates and judgements (continued)
Warranty provision 
The Group makes estimates in calculating the warranty provision for existing commitments arising from past events. 
In estimating the provision, the Group makes judgements as to the quantum and likelihood of the liability arising. 
Certain provisions require more judgement than others. In particular, the warranty provision has to take account 
of future outcomes arising from past deliveries of products and services. In estimating these provisions, the Group 
makes use of management experience, precedents and any specific contract and customer information.
Critical judgements in applying the Group’s accounting policies
The critical accounting judgements in applying the Group’s accounting policies are considered below and are the 
judgements that have the most significant effect on the amounts recognised in the financial statements.
Development costs
Development costs are capitalised in accordance with the accounting policy in note 1 if it meets the criteria as per 
IAS 38. Initial capitalisation of costs is based on management’s judgement whether the criteria of IAS 38 is satisfied, 
when the technological and economical feasibility is confirmed, usually when a product development project has 
reached a defined milestone and there is commercial interest in the product. As part of this judgement process, 
management establish future demand relating to the product, evaluate the development plans to complete the 
product and establish where the development is positioned on the Group’s technology roadmap. The directors 
apply judgement in the review of costs capitalised to determine whether any impairment should be recognised. The 
directors also apply judgement in its review of impairment of its development costs and assesses this on a regular 
basis to ensure that any costs still capitalised continue to be commercially viable.

Segmental analysis
Operating segments
IFRS 8 requires consideration of the identity of the chief operating decision maker (‘CODM’) within the Group. In line 
with the Group’s internal reporting framework and management structure, the key strategic and operating decisions 
are made by the Board, who reviews internal monthly management reports, annual business plans and forecast 
information as part of this. Accordingly, the Board is deemed to be the CODM.
The CODM has identified one operating segment within the Group as defined under IFRS 8. In turn, this is the 
only reportable segment of the Group as the entities in the Group have similar products and services, production 
processes and economic characteristics. Therefore, there is no allocation of operating expenses, profit measures or 
assets and liabilities to specific commercial markets. 
Accordingly, the CODM assesses the performance of the operating segment on financial information which is 
measured and presented in a manner consistent with those in the financial statements by reference to Group results 
against budget.
The Group profit measures are operating profit and adjusted EBITDA, both disclosed on the face of the 
consolidated income statement. No differences exist between the basis of preparation of the performance 
measures used by management and the figures in the Group financial statements.
The Group has three customers representing individually over 10% of revenue each and in aggregate 84% of 
revenue. This is split as follows:
•	 Customer A	 -	 48% (2023: 12%)
•	 Customer B	 - 	19% (2023: 34%)
•	 Customer C	 - 	17% (2023: 17%)
Geographical information
In presenting information on the basis of geographical segments, segment revenue is based on the geographical 
location of customers and the nature of revenue recognised. Segment assets are based on the geographical 
location of the assets.

Goodwill and other intangibles relate to the acquisition of Isotek (Holdings) Limited. Goodwill is allocated to 
the CGUs that were expected to benefit from the synergies of the combination and which represents the lowest 
level within the Group at which the goodwill is monitored for internal management purposes. The Group tests 
goodwill annually for impairment or more frequently if there are indications that goodwill may be impaired.
The carrying value of intangible assets and goodwill has been assessed for impairment by reference to its value 
in use. Value in use was determined by discounting the future cash flows generated from the continuing use of the 
CGUs. The calculation of the value in use was based on the following key assumptions:
•	 Budgets incorporating pre-tax cash flows have been prepared to 31 May 2025 based on past experience, actual 
operating results, known future cash flows and estimates of future cash flows;
•	 Cash flows for a further four years have been prepared based on the Company’s long range plan together with 
cost inflation and additional overhead assumptions. A perpetuity factor has been applied based on the year to 
31 May 2029. A long-term growth factor of nil was applied to the perpetuity cash flows; and
•	 The Group’s pre-tax discount rate of 16% (2023:14%) was applied in determining the recoverable amount of the 
unit, being the estimated weighted average cost of capital for the CGUs.
Based on the testing above the directors do not consider any of the remaining goodwill or intangible assets to be 
impaired, even allowing for a reasonable degree of sensitivity to the underlying assumptions, including the discount 
rate.

Deferred tax
17
Deferred tax assets within the UK and the USA have been recognised as the directors consider that future taxable 
profits will be available against which they can be used. Future taxable profits are determined based on business 
plans for individual subsidiaries in the Group and the reversal of temporary differences. 
Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable 
that the related tax benefit will be realised; such deductions are reversed when the probability of future taxable 
profits improves.

The provision for warranty relates to the units sold during the last two financial years. The provision is based on 
estimates made from historical warranty data. Factors that could impact the warranty provision include the success 
of the Group’s quality initiatives as well as parts and labour costs. The provision is expected to be utilised in the next 
two financial years.

The Group leases physical facilities at its three sites in the UK and one in the USA with each of these leases requiring 
the site to be restored to its original condition. The dilapidation provision reflects management’s best estimates and 
ability to measure the likely costs that may be incurred restoring the building to its original state. Settlement will be 
made on exit from each property. There are currently no plans to leave any of the Group’s properties.

Contract liabilities are invoices raised in advance of NRE work completed for customers that will be recognised as 
income once the performance obligation of the contract has been met. The majority of NRE contracts are invoiced 
with a proportion of the contract value upfront which is recognised as revenue, over time, across the life of contract 
at each milestone based on the percentage of the overall contract value achieved at that performance obligation.
A capital grant of £150,000 was awarded in the year towards the purchase of a new die attach machine to 
support new product introductions. Capital grants are amortised over a period of up to eight years in line with the 
preparation period of the machinery.

Sharesave plans
Seven sharesave plans have been offered to employees over the years, at the date of this report. The first six of the 
schemes offered to employees have now closed. Under these plans employees who join the plan can save up to 
£500 per month for three years. The members of the plans are granted a number of share options based on the 
amount they would save over the three years. At the end of the three years, the members have a six-month period in 
which they can exercise the share options. The scheme has an exercise price calculated by reference to the average 
of the middle market closing price of the shares on AIM for the dealing day immediately prior to the plan offer date.
29
The weighted average price of the outstanding options under this scheme at 31 May 2024 was 16p (2023: 9p).

The share options expense is the fair value of the share options at the date of grant spread over the expected 
vesting period of the share options. The fair value of the share options at the date of grant was measured using the 
Black–Scholes model.
The inputs to the Black–Scholes model and the weighted average fair value of the share options granted during the 
year were as follows:
*Expected volatility is the estimate of the volatility of the share price over the expected life of the share options.

As part of the Strategic Partnership with SpaceX announced on 24 April 2024, the Company issued a total of 
21,712,109 warrants to SpaceX across two tranches, to enable SpaceX to subscribe for up to a maximum of 10% 
of the Company’s existing share capital at the time of the signed agreement, with such warrants expected to vest on 
a variable basis, with full vesting of the warrants once approximately $60m (£48m) of orders have been placed by 
SpaceX. The two warrant tranches, which are split equally, are detailed below: 
Tranche 1:	 a maximum of 5% vesting on a variable basis from order flow of the E-band SSPA platform; and
Tranche 2:	 a maximum of a further 5%, also vesting on a variable basis, for order flow of products developed at  
	
alternative frequency bands which would involve partnering with SpaceX on new product  
	
development.
Summary of warrant terms
1)	 Filtronic issued SpaceX with equity warrants up to a maximum of 5% of its share capital at the time of the 
agreement (10,856,055 warrants) and such warrants will vest based on the receipt of purchase orders against 
a staged vesting profile for E-band SSPA modules. All warrants in this tranche will fully vest once SpaceX has 
placed a minimum of $37m (£30m) of irrevocable purchase orders with Filtronic.
 2)	 Filtronic issued SpaceX with additional equity warrants up to a maximum of another 5% of its existing share 
capital (10,856,054 warrants). Such warrants will vest based on the receipt of purchase orders, against a 
staged vesting profile for SSPA modules at other operational frequency bands. The warrants in this tranche will 
fully vest on a similar profile to those in point 1.
3)	 The strike price for the warrant 33 pence, being the closing mid-market price of Filtronic’s ordinary shares of 
0.1p each on 23 April 2024, being the last business day before the Strategic Partnership contract was executed.
4) 	 SpaceX must place a minimum order value in each subsequent 12-month period from the Contract Date of 
$10m to be delivered within 12 months. SpaceX must also maintain a cadence of order flow, so that the timing 
between purchase orders does not surpass a 12 month-period. If order flow is not maintained in accordance 
with these two tests, within the 5-year warrant period, then the warrants will expire 6 months from that date.
5)	 The warrants will expire five (5) years from the date the Strategic Partnership contract was executed. The 
warrants will expire earlier if certain minimum order volumes are not met by SpaceX. Vested warrants can be 
exercised in whole (or in part, in minimum amounts of 500,000) at any time prior to their expiration, to the extent 
the agreed vesting conditions have been satisfied.
21,512,000 of the warrants are being issued utilising (to their full extent in this particular regard) the existing 
shareholder authorities granted at the Annual General Meeting of the Company held in October 2023, with the 
remaining balance (of 200,109 warrants) to be issued following the grant of similar authorities at this year’s Annual 
General Meeting.

Financial instruments
Fair value
The carrying amount of all the financial assets and liabilities approximates to their fair value at acquisition as 
described below.
Cash and cash equivalents comprise bank balances and bank deposits with a maturity of three months or less.
Trade and other receivables are all receivable in less than one year. Trade receivables are generally receivable within  
90 days.
Trade and other payables are all payable in less than one year. Trade payables are generally payable within 90 
days.
All financial assets and liabilities are held at amortised cost other than derivative financial instruments which are held 
at fair value.
Liquidity risk
The Group has cash at bank of £7.2m. 
Cash is held on bank deposit for varying periods from overnight to six months to ensure all liabilities can be met as 
they fall due. 
The Group has access to a £3.0m sales invoicing facility with Barclays Bank.
The sales invoicing facility with Barclays Bank allows the Company to borrow 70% of the UK entities’ debtors 
denominated in US dollars and sterling up to a value of £3.0m. 
The Group had a sales invoice factoring facility with Wells Fargo Bank which allowed the Company to borrow 85% 
of the US entities’ debtors denominated in US dollars up to a value of $4.0m. The arrangement was terminated 
effective from 12 July 2024.
The amount of cash available to the Group and the headroom available on debt facilities results in a low liquidity risk.
Credit risk
The exposure to credit risk is limited to the carrying amount of cash and cash equivalents and trade and other 
receivables in the statement of financial position.
The credit risk related to cash and cash equivalents is considered to be low due to the cash being held at banks with 
high credit ratings such as Barclays Bank and Wells Fargo Bank.

Credit risk is primarily related to trade receivables. The Group’s businesses are concentrated on long-term 
relationships with a small number of large and long-established OEMs. Payment terms for trade receivables range 
from prepayment terms to 90 days net. Overdue receivables are regularly monitored and appropriate action is 
taken to collect payment. The Group has historically incurred only low levels of unrecoverable receivables. Therefore 
credit risk is considered to be low.

The age of trade receivables that have not been provided for was as follows:
No expected credit loss is considered necessary in either FY2024 or FY2023.
Interest rate risk
Cash is generally held on short-term bank deposits which earn interest at variable money market deposit rates. At 
31 May 2024, there was £nil held on short-term deposit. The remaining cash in the Group is held in very low interest 
rate bank accounts. Sterling interest rates are very low and therefore interest rate risk is considered to be low.
The interest rate sensitivity of the expected annual interest income/(expense) assuming a balance on deposit or 
loan of £1,000,000 is as follows:

Foreign currency risk
The Group’s reporting currency is sterling. The functional currencies of the subsidiaries are sterling, US dollar and 
Chinese yuan.
The Group’s results and financial position are affected by fluctuations in foreign currency exchange rates.
The Group has generated a surplus of US dollars during the year due to an increasing number of projects being 
supplied in US dollars. Whilst the Group aims to maintain a natural hedge, it is not adequate to offset the exposure 
on currency risk. Therefore, the Group has used forward foreign exchange contracts to reduce the currency risk 
from surplus US dollars. The nature of the Group’s businesses means there is limited visibility of the currency 
required in US dollars. Therefore, when forward contracts are used to reduce currency risk, they are usually only for 
short periods of no more than six months. If the US dollar were to weaken significantly, this could materially reduce 
the Group’s revenue and operating profit. 
There was a forward contract in place at 31 May 2024, the fair value of the foreign currency contract was an asset 
of £40,000 (2023 : £34,000) liability.
Cash is mainly held in sterling and US dollars.

If the US dollar had been 1% stronger/weaker against sterling throughout the year ended 31 May 2024, then the 
Group operating profit would have been £184,000 higher/lower. The impact of other currencies is not material.

Capital management
The capital structure of the Group and Company consists of equity and debt. Equity comprises ordinary share 
capital and retained earnings. Debt includes sales invoice financing facilities with large banks, asset finance and 
lease liabilities.
The objective when managing capital is to safeguard the Group’s ability to continue as a going concern in order to 
maximise future returns for shareholders.
Cash flow is controlled by ongoing justification, monitoring and reporting of capital expenditure and regular 
monitoring and reporting of operational costs.

The investments in subsidiaries are assessed annually to determine if there is any indication that any of the 
investments might be impaired. The assessment of the carrying amount is derived from the higher of the value in use 
and the fair value less costs to sell. Value in use is determined by discounting the future cash flows generated from the 
continuing use of the cash generating unit (“CGU”) to which the investment relates whilst the fair value less costs to sell 
is the amount that a market participant would pay for the asset or CGU, less the costs of sale.
The carrying amount was calculated using the value in use model which returned a higher carrying value based on 
the following key assumptions:
•	Budgets incorporating post-tax cash flows have been prepared to 31 May 2025 based on past experience, actual  
	 operating results, known future cash flows and estimates of future cash flows;
• 	Cash flows for a further four years have been prepared based on the Company’s long-range plan together with 	  
	 cost inflation and additional overhead assumptions. A perpetuity factor has been applied based on the year to 31  
	 May 2029. A long-term growth factor of 5% was applied to the perpetuity cash flows; and 
• 	The CGU has a pre-tax discount rate of 16% (2023:14%) which was applied in determining the recoverable  
	 amount of the unit, being the estimated weighted average cost of capital for the CGU. 
The investments in subsidiaries are assessed annually to determine if there is any indication that any of the 
investments might be impaired. At 31 May 2024 it was identified that the investment in the CGU responsible for RF 
conditioning products would need to be impaired by £0.3m based on discounting the future cashflows following 
a review of budgets. The recoverable amount of £nil was determined based on a value-in-use calculation which 
requires the use of key assumptions. A key input of the model is the discount rate used. Therefore a +/- 1% difference 
in the discount rate would impact impairment by £249,000 on +1% and £278,000 on -1%.

Fair value
The carrying amount of all the financial assets and liabilities approximates to their fair value as described below. 
Cash and cash equivalents comprise bank balances and bank deposits with a maturity of three months or less. 
Trade and other receivables are all receivable in less than one year. 
Trade and other payables are all payable in less than one year. Trade payables are generally payable within 30 
days. 
All financial assets and liabilities are held at amortised cost.
Liquidity risk
The Company has cash at bank of £36k. Cash is held on bank deposit for varying periods from overnight to six 
months to ensure all liabilities can be met as they fall due. The amount of cash available to the Company and the 
money available in the Group results in a low liquidity risk.
Credit risk
The exposure to credit risk is limited to the carrying amount of cash and cash equivalents and trade and other 
receivables in the statement of financial position. The credit risk related to cash and cash equivalents is considered 
to be low due to the cash being held at banks with high credit ratings such as Barclays Bank.
Credit risk is primarily related to Group receivables in the form of intercompany loan arrangements. Therefore, 
credit risk is considered to be low.
The Company has no trade receivables.
Interest rate risk
Cash is generally held on short-term bank deposits which earn interest at variable money market deposit rates. 
Cash is held in low interest rate bank accounts and therefore interest rate risk is considered to be low.
Foreign currency risk
The Company’s reporting and functional currency is sterling with very limited exposure to foreign currency. 
Therefore, the Company has little foreign currency risk.
Capital management
The capital structure of the Company consists of equity and debt. Equity comprises ordinary share capital and 
retained earnings. Debt includes lease liabilities. 
The objective when managing capital is to safeguard the Company’s ability to continue as a going concern in 
order to maximise future returns for shareholders. Cash flow is controlled by ongoing justification, monitoring and 
reporting of capital expenditure and regular monitoring and reporting of operational costs.
