Chairman’s statement
Introduction
I am extremely pleased with the performance of CML over 
the last few years, and my colleagues throughout the whole 
Group should be justly proud of their achievements against a 
very challenging backdrop. This has been a transformational 
time for the Company, set against a period of numerous macro 
headwinds including COVID-19, Brexit, the conflict in Ukraine 
and increased economic and geopolitical uncertainty. It is 
therefore encouraging to see the business moving forward in 
such a positive manner. 
The communications semiconductor market is one in which 
we have operated for over 50 years. It is a market we 
understand, where we have good customer relationships and 
see tremendous growth opportunities, as explained within 
the Strategic Report that follows. I am pleased to report that 
our strategy of concentrating our efforts on this market and 
expanding the sub-sectors we address is working well. Our focus 
on organic growth supplemented with appropriate acquisitions 
is beginning to yield the anticipated results.
We are still in the process of securing the exciting opportunity for 
the proposed acquisition of Microwave Technology, Inc (“MwT”) 
which we announced on 17 January 2023. This is currently 
subject to the US regulatory clearance process, and we are in 
the final stages. Once completed, we will have substantially 
expanded the Group’s product portfolio, strengthened and 
enhanced our support resources and increased our R&D 
capabilities. Additionally, this will add to the Group’s expertise 
through expanding our system level understanding, product 
manufacturing and packaging techniques, allowing us to 
capitalise on the market opportunity more effectively.
Results
Our financial focus is on constantly improving results in a number 
of areas, including revenues, operating profit, balance sheet 
strength and cash. While it is pleasing to show significant pre‑tax 
profit growth in the income statement, we strongly believe that 
it is the operating profit line (excluding exceptional items) which 
most effectively demonstrates how the underlying business is 
performing. Exceptional items tend to be non‑recurring, such 
as this year’s profit on the disposal of excess land. That said, this 
extra profit is an important supplement to the progress being 
made and is obviously cash generative.
I am delighted with the strong organic growth achieved this 
year. Revenues increased 22% year-on-year to £20.64m (FY22: 
£16.96m), reflecting good progress across the established 
product range alongside the newer products which are already 
starting to make meaningful progress. 
The gross profit margin was maintained on the revenue increase 
but with inflationary pressures, a general increase in global 
business activity levels and acquisition related costs, expenses 
increased. Profit from operations before exceptional items 
increased to £2.93m (FY22: £1.21m), an advance of 142%. The 
growth in profit before tax to £5.22m (FY22: £1.74m) was assisted 
by the completion on the sale of the first parcel of excess land 
at Oval Park, yielding a £2.06m profit and occurring just prior to 
the year-end. Adjusted EBITDA improved 37% to £5.90m (FY22: 
£4.31m). Despite the share buyback programme and dividend 
payments, net assets per share grew 7% to 319.65p (FY22: 
299.81p) and the Group’s cash position remained healthy at 
£22.6m with no debt (FY22: £25.04m).
Our focus on organic growth supplemented 
with appropriate acquisitions is beginning to 
yield the anticipated results.

Property
Following our announcement on 17 February 2023 regarding 
the grant of planning permissions on excess land at the 
Group’s Essex Headquarters site, Oval Park, as stated in the 
results section, I am pleased to note that we completed 
the sale of the first parcel of land just prior to the year end. 
Following this transaction, circa 15 acres remain available for 
disposal.
Additionally, the Group has commercial property in Fareham, 
Hampshire, that is excess to operational needs and therefore 
held for sale. Negotiations are currently in progress regarding 
this site. 
The Board’s objective of raising cash from its excess property 
interests remains important as this will help to yield funds for 
future acquisition opportunities and/or allow the return of 
additional monies to shareholders. I must again stress these 
property transactions are separate from, and additional to, 
the Group’s planned operational profits growth.
Share Buyback and dividend
Through the year, £3.65m net was spent on the share 
buyback programme (£4.77m purchased net of £1.12m 
issued in satisfaction of employee share options) and, 
following the financial year end in April, a further £1.75m 
was spent on an additional buyback. This shows the Board’s 
continued commitment to returning funds to shareholders 
and enhancing earnings where possible.
The Board continues to maintain its progressive dividend 
policy whilst ensuring it has adequate cash to cover its 
growth objectives, including strong R&D investments, and 
the completion of the MwT acquisition. The interim dividend 
was increased from 4p to 5p per share and the Board is 
recommending an increased final dividend of 6p per share, 
taking the full year dividend to 11p per share (FY22: 9p per 
share). This is an increase for the full year dividend of 22% 
and reflects the Board’s confidence in the future. Subject 
to shareholder approval, the dividend will be paid to 
shareholders on 18 August 2023 whose names appear on the 
register at close of business on 4 August 2023.

ESG
The Company has an Environment, Social and Governance 
(“ESG”) strategy that is supporting sustainable and inclusive 
economic growth. We believe that it is important to focus our 
efforts on areas where our actions can “make a difference”, 
rather than simply paying lip service to the topic. Full 
disclosure of how we address this subject can be found in the 
Group’s Annual Report and Accounts. 
Employees
Clearly the life blood and success of any company is 
attributable to its workforce, and on behalf of the Board 
I would like to thank every one of our employees for their 
energy, enthusiasm and commitment which is evident to 
all and much appreciated.
Outlook
As a business, we are confident that the strategy we 
are following is going to yield the sustainable long-term 
growth we are looking to achieve and these results are a 
clear endorsement of this. That said, it is important not to 
underestimate the ongoing challenges facing the Group, 
not only within our market sector, but the global economy 
in general. 
Whilst headwinds do persist, I believe the Group is well 
placed to navigate these challenges effectively and 
continue our growth trajectory. 
We have exciting opportunities ahead of us, an expanding 
product line and a robust ongoing R&D programme. 
In addition to this, we have the planned assimilation of 
MwT into the Group with the expected benefits from the 
combined business helping to expand expertise, increase 
operational efficiencies and scale alongside the market. 
Whilst this will be another busy year for the Group, we look 
to the future with confidence that further progress will be 
made against our strategic objectives.

Strategic pillars
Strategic focus
The Group’s strategic focus is to deliver 
technologically innovative, market-leading solutions 
through timely and effective market research and 
engineering development, focusing our resources 
effectively to enhance our customer relationships.
We seek to expand our total addressable market 
through existing customer proliferation and new 
customer adoption in current and adjacent 
market areas.
We grow customer share and expand the 
customer base through R&D investments that 
increase the functionality that our integrated 
circuits (ICs) deliver within the customers’ end 
product. This includes growing the product portfolio 
to include ICs with performance characteristics 
intended to widen the addressable market.
Cascaded strategy
The Group puts the customer at the heart of 
everything we do. By focusing on their aims, 
we ensure that we never lose sight of what’s 
important. It is a fabless semiconductor company 
with worldwide reach and operations.
•	 Partner with our customers to solve 
technology problems in voice and data 
communication applications.
•	 Leverage our world-beating systems 
and IC design knowledge to provide 
innovative solutions.
•	 Prioritise our customers’ needs, ensuring we 
remain vigilant in designing products and 
capabilities that support their objectives.
We have three key principles behind executing our strategy:
Quality 
Superiority and excellence are 
important definitions of quality 
within our organisation and 
are widely applicable across 
numerous activities. Whether it is 
product design, manufacturing, 
selling or stakeholder relationship 
management, we strive to be a 
quality company operating with the 
high levels of business acumen and 
ethical practices that the business 
was founded on.
2
Support 
Superlative customer support is part 
of CML’s DNA. It is a key trait that 
customers associate us with; and 
an important factor in customers’ 
decision‑making process to 
select us as a long‑term supplier 
and partner. A thorough “system 
knowledge” of the end‑application 
within the markets that we address 
underpins our long‑standing 
reputation.
3
Innovation 
Technical innovation is a 
fundamental contributor to the 
Group’s success. Our marketing 
and engineering personnel 
collaborate to define and deliver 
compelling, commercially 
attractive semiconductor 
solutions. Our extensive and 
growing silicon and software IP 
portfolio can be combined using 
optimal partitioning for a specific 
end market to achieve the right 
balance between performance 
and cost.
With the launch of the SµRF product 
range, we are creating a strong 
product portfolio to address the 
5G, Satellite and IoT markets. We 
are continually evolving to enable 
the Group to expand into new

Principal risks and uncertainties
The principal risks and uncertainties facing the Group are:
Key risks of a financial nature
Foreign exchange
With the majority of the Group’s earnings being linked to the US Dollar, a decline in this currency will have a direct effect on revenue, although since the 
majority of the cost of sales are also linked to the US Dollar, this risk is reduced at the gross profit line. 
Customer dependency
The Group has a very diverse customer base generally, however in certain market sectors, key customers can represent a significant amount of revenue. Key 
customer relationships are closely monitored; however, changes in buying patterns of key customers could have an adverse effect on the Group’s performance.
Supply chain dependency, interruption 
and cost inflation
The Group has a number of key supplier relationships, which are closely maintained to minimise the impact from any potential supply chain disruption. 
Some of the raw materials used within the Group’s semiconductor products are sole sourced from highly specialised suppliers on a global basis. To partially 
mitigate unexpected but temporary raw material delivery delays, an appropriate level of excess inventory is held. If a key raw material supplier was unable to 
continue supply on a permanent basis, then the Group would need to invest the R&D effort and associated costs to replace the supplier, subject to that being 
considered commercially viable. 
Supplier prices, currency exchange rates and gross margins are continually monitored which can lead to pricing adjustments with customers.
IT system – failure or malicious damage
The Group has a standardised systematic approach to maintaining and operating its IT systems globally consisting of an internal team supported by a number 
of world class external partners. The backup and recovery of its global IT systems has been real-time tested. The threat from malicious cyber activity is an 
ever‑increasing risk with awareness and responsibility at Board level and appropriate investments being made.
Cost-of-living crisis
During 2023, a cost-of-living crisis has been triggered due to the combined impact of COVID-19 and the various economic effects of the Russian invasion 
of Ukraine. Rising energy prices and supply chain dependency are contributing to significant price inflation and associated rises in interest rates. The Group 
understands that this is impacting all aspects of day-to-day living and placing real pressure on the current market and are continuing to monitor the impact.
Key risks of a non‑financial nature
Customer product demand
The Group is a small player operating in a highly competitive global market that is undergoing continual and geographical change. The Group’s ability 
to respond to many competitive factors including, but not limited to, pricing, technological innovations, product quality, customer service, raw material 
availabilities, manufacturing capabilities and employment of qualified personnel will be key in the achievement of its objectives. The Group’s ultimate 
success will depend on the demand for its customers’ products, since the Group is a component supplier.
Legal requirements
A substantial proportion of the Group’s revenue and earnings are derived from outside the UK and so the Group’s ability to achieve its financial objectives 
could be impacted by risks and uncertainties associated with local legal requirements (including the UK’s withdrawal from the European Union, or “Brexit”), 
political risk, the enforceability of laws and contracts, changes in the tax laws, terrorist activities, natural disasters or health epidemics.
Understanding of the development, 
performance or position of the 
Company’s business
The Directors do not believe that environmental matters (including the impact of the Company’s business on the environment), details of the Company’s 
employees (including gender) and social, community and human rights issues are needed for an understanding of the development, performance or 
position of the Company’s business and accordingly have not included these within the Strategic Report, but have added these to the Directors’ Report 
and Environment, social and governance sections of this Annual Report.

Group Managing Director’s review
Introduction
For the year to 31 March 2023, our ambition was to deliver 
a firm improvement in the Group’s financial and operational 
performance. It is very satisfying to report that those objectives 
were accomplished despite a challenging macroeconomic 
backdrop and prolonged electronic component supply chain 
challenges amongst the Group’s customer base.
According to a number of industry commentators, the 
semiconductor market as a whole grew by 3-4% for the 
calendar year to December 2022, with the second half weaker 
than the first. In comparison, the Group’s full year revenues to 
31 March 2023 advanced by 22% with the second six-month 
period delivering a stronger performance than the first. This 
highlights the resilience of the Group’s end markets where 
the focus is currently weighted towards industrial and critical 
communications application areas in contrast to the memory, 
personal computer and consumer markets which tend to 
exhibit more volatility.
The improvement in profitability for the year is further 
validation of the Group’s pivotal decision to divest our 
Storage Division in 2021 in favour of an increased focus 
on global communications markets, with expansion into 
end‑applications requiring microwave and millimetre wave 
(mmWave) products a key major objective.
Good progress is being made in this area, with the Group 
continuing to invest heavily in research and development 
activities targeted at products for application areas that are 
expected to drive growth over the coming years, along with 
the investment in the personnel and equipment required for 
the business to maintain a competitive edge.
Strategy
The Group’s vision is to be the first-choice semiconductor 
partner to technology innovators, together transforming how 
the world communicates.
Our focus is on the definition, development and marketing 
of standard Integrated Circuit (“IC”) products that deliver 
compelling technical and commercial benefits to our 
customers. In turn, our customers utilise these solutions to 
develop and subsequently market end-products that are 
essential for the efficient and reliable transportation of voice 
and/or data across a predominantly wireless medium.
The global communications market is huge, with a myriad of 
end-application areas ranging from mobile/cellular networks 
to precise positioning systems to short-range remote-control 
devices. Within this vast landscape of opportunity, CML is 
actively participating in a number of sub-markets that play 
to our strengths and have excellent growth potential on 
a sustainable basis. These markets include mission critical 
communications, wireless networks and satellite, Industrial 
Internet of Things (“IIoT”) and more recently, broadcast radio. 
The addressable market in terms of semiconductor content 
easily exceeds $1 billion.
Continued investment in research and development is 
essential to allow CML to take full advantage of the large 
market opportunity available. The Group’s product portfolio 
is evolving to support customer requirements for size, cost 
and performance enhancements whilst also encompassing 
new technologies that will permit entry into markets that were 
previously not addressable.
Subject to unforeseen circumstances the period to 
31 March 2024 is expected to be a further year of improvement, 
with solid growth in revenues and operational profitability.

Strategy continued
Our strategy for allocating capital to R&D comprises four main 
areas of investment; “Defend & Grow” revenues in core CML 
markets, expand into adjacent markets (SµRF product range), 
innovative product initiatives aimed at new high-growth 
markets and an element of internal research and innovation 
that could benefit any or all of the aforementioned categories. 
Markets
The mission critical communications sector is a multi-billion 
dollar market that is estimated to grow at a CAGR of close 
to 9% over the next five years. Applications include public 
safety, government agencies, transportation, energy 
and utilities, mining and others. Growth is being driven by 
the increased adoption from energy and utility sectors, 
rising investment by defence sectors and trends within 
the transportation industry where real-time data is being 
used to support dynamic decision-making. Mission critical 
communications has been a cornerstone of CML’s global 
business for many years and the year under review was no 
exception. An overall increase in revenues from the Group’s 
top customers who are active in this sector contributed well 
to the Group’s underlying performance. Outside of mission 
critical end markets, revenues from customers producing 
similar products for industrial and commercial business users, 
also grew well and overall, the two sectors combined to 
deliver a very pleasing performance across the year. 
One area where the Group sees great potential is the rapid 
development of 5G and satellite-based communications. 
Advancements in this area are propelling us towards a 
future where faster, cheaper, and more accessible internet 
connectivity becomes a reality for all. 5G’s high‑speed, 
low‑latency capabilities, combined with satellite technology’s 
wide coverage and reach, enable a bridging of the 
digital divide, connecting remote regions, enabling faster 
communication and empowering industries. To build this 
new reality, a vast 5G network of base stations, small cells 
and other mmWave infrastructure will be required. 
Using our expertise in advanced compound semiconductor 
IC design, CML has begun producing high performance 
RFICs and MMICs that are relatively simple to use from a 
customer perspective, but have the technical characteristics 
and commercial competitiveness required to be successful 
in these mass-market applications areas. FY23 represented 
the first full year period of availability for a number of new 
products that are marketed under CML’s SµRF brand. Prior 
year product releases have started generating income 
and, over time, the flow of revenue from this portfolio of IC’s 
is expected to constitute a very sizeable proportion of the 
Group’s total revenues. 
CML has a long history in supporting IIoT & M2M applications, 
with decades of experience in helping to solve customers’ 
design problems. Our semiconductor solutions include 
off‑the‑shelf baseband modem ICs, offering engineers 
a fast time to market by avoiding unnecessary software 
development. 
These products typically provide high performance with 
relatively low-power consumption and are highly integrated, 
targeting application areas including M2M, automatic meter 
reading (“AMR”), advanced metering infrastructure (“AMI”), 
asset tracking and, more recently, RFID. Combined product 
shipments into the Group’s top customers active in these 
sectors was slightly weaker than the prior year due in part 
to the unusual purchasing patterns that some customers 
employed whilst navigating through their own supply chain 
disruptions across the last two years.
Towards the end of the financial year, a key R&D initiative 
that fits the “innovative product for new high-growth markets” 
category reached the stage of development whereby 
it could be released to early adopters. This new product 
represents a first for CML in that it paves the way for entry into 
the broadcast radio market which, although invented more 
than 100 years ago, remains a highly important media. In 
many parts of the world radio remains the method whereby 
large populations get their trusted news and information and 
in times of natural disaster provides a vital service when other 
infrastructure has been compromised.

Markets continued
Digital Radio Mondiale (“DRM”) is a digital radio broadcast 
standard that has been adopted for wide area broadcasting 
in China, India and Pakistan whilst being targeted for 
deployment in several other emerging nations in the near 
term. In India, near national area coverage is achieved 
from 35 transmitting sites. The DRM service provides high-
quality stereo audio across long distances and wide areas. 
DRM is an “open standard” to ensure a wide diversity of 
equipment, receivers, and IP suppliers. The radio spectrum is 
a limited natural resource, DRM uses that resource more cost 
effectively than analogue or other digital broadcast methods 
whilst the infrastructure required for DRM is both low cost and 
low power – offering a 10:1 power consumption advantage 
over equivalent analogue FM transmissions.
Current DRM IC solutions are targeted at the automotive 
market where low-power operation is less of a necessity and 
they are therefore not well suited to portable receivers. CML 
has developed a highly integrated Software Defined Radio 
(“SDR”) tuner IC targeted at the market for DRM receivers. 
To complement the IC, CML has worked with Cambridge 
Consultants Limited to produce a miniature module, seen as a 
core component to implement a full DRM capable broadcast 
receiver covering all transmission bands. The IC will be sampled 
during the first half of this financial year with full launch of the 
module planned for the second half.
The Group’s market exposure is evolving in tandem with a 
number of new and emerging growth sectors that have 
something in common, a fundamental need for semiconductor 
solutions that CML has the inherent capability to produce. 
Operations
During the year, the Group formally launched seven new 
products to market. The majority of these are for use in 
microwave or mmWave applications across a number of the 
previously mentioned market sectors. Customer adoption 
of the Group’s products marketed under the SµRF brand 
continues to gather pace, and progress during the first full year 
of production has been very encouraging.
One of our guiding principles is to foster a culture of quality 
with a sense of urgency. Operationally, the CML team 
continued to excel in that regard, despite the increased 
demands that an ongoing and rapid expansion of the product 
range places upon personnel and systems. Our future success 
depends upon the skills and dedication of our employees, and 
it is important to recognise the exceptional efforts being made 
by the whole team in that regard. 
The growing product range, coupled with a simultaneous 
expansion into new and adjacent market sectors places a 
great deal of emphasis on ensuring that the Group’s routes 
to market remain appropriate for the direction of travel that 
the business is taking. The process is one of evolution and 
refinement over time, and during the year, a number of 
enhancements were made, including territorial changes within 
Europe and new partners in the Americas and South Africa. 
Following travel and tradeshow restrictions due to the 
pandemic, the Company participated at a number of trade 
shows relevant to the sectors and industries being targeted. 
These included European Microwave week (London), 
IMS2022 (Denver) and BES Expo (New Delhi). These activities 
have led to an increase in associated costs that is further 
explained in the financial review that follows. However, they 
are an important ingredient for success given the strategy 
being followed and another year of strong investment is 
planned. 
The Group’s orderbook climbed significantly across the last two 
and a half years as customers placed longer term scheduled 
orders amidst concerns about the general supply situation 
for semiconductors that was extensively reported on at the 
time. It is apparent that the supply situation has improved and 
some customers are becoming more relaxed about product 
availability leading to adjustments to their ordering patterns. 
The Group’s order book remains healthy, at a level more than 
double that prior to the pandemic and stretching well into 
2024. A ‘new normal’ will be established following the unusual 
market dynamics of the last three years and the growth of the 
customer base as we continue to expand into wider markets.
Acquisition of Microwave Technology, Inc
On 17 January 2023 we announced the entering of a 
definitive agreement to acquire Silicon Valley based 
semiconductor company Microwave Technology, Inc. (MwT). 
Founded in 1982, MwT is a recognised leader in the design, 
manufacturing and marketing of GaAs and GaN based 
MMICs, Discrete Devices, and Hybrid Amplifier Products for 
commercial wireless communication, defence, space, and 
medical (MRI) applications.
The proposed acquisition expands the Group’s product 
portfolio, strengthens its support resources and increases its 
R&D capabilities. MwT’s products are complementary to CML’s 
and the majority of its focus and client concentration remains 
within the USA. The CML Board believes there is a significant 
opportunity to increase market share by internationalising 
MwT’s products. 
Currently, the transaction remains subject to US regulatory 
approval. Expectations were for the transaction to complete 
during the first half of 2023, however, the nature of the 
technology that MwT possesses along with the constitution of 
its customer base has necessitated extended discussions with 
the relevant US authorities whose remit it is to protect national 
security interests. Whilst a definitive date for completion is not 
yet available, we are in regular contact with the relevant 
departments and expect a conclusion to be reached in the 
coming weeks. A further announcement will be made at the 
appropriate time.

Outlook
Market expansion through the addition of microwave/
millimetre wave ICs to the Group’s product portfolio is now 
delivering tangible results, with good growth expected for 
the year ahead. A high level of R&D investment continues to 
ensure the Group is well placed to capture new opportunities 
within the markets that dominate the current revenue stream, 
whilst making appropriate investment into exciting new 
markets with strong growth potential. 
Clearly the world has its issues, not least geo-political 
uncertainties, an inflationary environment and economic 
uncertainty. Whilst remaining mindful of the backdrop and 
risk-aware, CML is focused on growth, with a confidence 
supported by our resilient existing markets, a healthy 
orderbook and an evolving presence in new and emerging 
growth sectors.
As is evident, the business continues to make good progress 
and has the appropriate blend of experience, enthusiasm 
and skills to continue to achieve its objectives. Subject to 
unforeseen circumstances the period to 31 March 2024 is 
expected to be a further year of improvement, with solid 
growth in revenues and operational profitability.
Financial review
Revenue
Group full year revenues of £20.64m (FY22: £16.96m) slightly 
exceeded market expectations that had been raised at 
the time of the interim results, after factoring in the positive 
momentum being achieved. This increase in revenues 
represented growth of 22% over the prior year and was 
assisted by a foreign exchange tailwind. Currency effects are 
less pronounced at the gross profit level where the Group has 
a somewhat natural hedge, due to a significant amount of 
raw material procurement being conducted in US Dollars.
The revenue advances were broad-based across the 
three main geographical areas addressed, with the Far 
East (+25%) and Americas (+35%) delivering the strongest 
gains and Europe 8% higher. It is important to note that 
annual revenue comparisons by region can be misleading 
because customers can and do alter their manufacturing 
locations periodically. From a customer perspective, close 
to 80% of the top 25 customers grew their business with 
CML year‑on‑year with the dominant sectors addressed 
encompassing narrowband voice communications and 
mission critical data applications.
Gross profit
Gross profit for the year was £15.61m (FY22: £12.80m), 
representing a 21% increase. This is a pleasing outcome 
given the raw material price rises encountered and the 
need to impose increased prices across the Group’s product 
range on more than one occasion. At the start of the year, 
higher inventory costs were anticipated, and allowances 
were factored into managements’ growth expectations, 
nevertheless, the operational teams responsible deserve 
much credit for achieving the targeted outcome.
Distribution and administration costs
D&A expenses increased by 9% to £12.64m (FY22: £11.56m). 
One driver was the resumption of certain business activities such 
as travel, marketing and exhibition costs as countries around the 
world eased their COVID-19 restrictions. There was an increased 
need to support the workforce in navigating a high inflationary 
period through a combination of salary rises and cost of living 
payments, whilst higher energy prices, acquisition related costs 
and the amortisation of development costs also added to the 
overall increase.
The Group continued with a strong level of R&D investment 
focused at capitalising on the secular growth expected from the 
market and application areas being targeted. R&D expenditure 
for the year was slightly up in absolute terms at £5.13m (FY22: 
£4.79m) but expressed as a percentage of sales, fell to 25% 
(FY22: 28%). Of this amount, £0.68m was expensed (FY22: £1.26m) 
with the balance capitalised under the Group’s research and 
development policy.
Operating profit
As per the previous financial year, a strong sales performance 
supported by stable gross margins drove the Group’s profit 
from operations before exceptional items to £2.93m (FY22: 
£1.21m) with other operating income contributing £0.20m 
(FY22: £0.08m). This results in a doubling of the operating 
margin before exceptional items to 14% (FY22: 7%) and is 
particularly pleasing given the industry-specific headwinds 
over recent years along with the prevailing inflationary climate.
Profit before tax
Excluding the exceptional profit realised from the sale of 
excess land at the Group’s Oval Park Headquarters, profit 
before tax and exceptional items improved by 77% to £3.16m 
and included net finance and other income of £0.23m (FY22: 
£0.57m).
As reported in recent years, the Group has been actively 
engaging with the local authority and interested parties to 
obtain planning permission on and subsequently dispose 
of excess land at the CML Group headquarters in Essex, 
UK. During the period leading up to the financial year end, 
detailed planning permission was obtained on two separate 
parcels of land along with outline planning permission 
for a business park on a third plot. One land parcel was 
successfully divested during March 2023 and the profit from 
that transaction amounted to £2.06m. While there is no 
certainty on the timing for realising value from the remaining 
excess land, the Company continues to engage with 
interested parties and currently expects to conclude the 
disposals during the next twelve months.
The total profit before tax recorded for the year was £5.22m 
(FY22: £1.74m).
Profit after tax
The Group continued to benefit from the R&D tax credit 
scheme that has existed for some years in the UK. For the year 
under review, tax assessed for the period is lower than the 
19% standard rate of corporation tax in the UK, providing an 
effective tax rate of 7.8%.

EPS
Excluding the exceptional property transaction previously 
mentioned, fully diluted earnings per share for the year 
climbed by 161% to 19.20p (FY22: 7.35p). When profits from 
the land sale are included, diluted earnings per share 
equated to 29.93p (FY22: 7.35p).
Dividend
The Board is proposing a final dividend of 6p (FY22: 5p), giving 
a full year dividend of 11p (FY22: 9p) as communicated In the 
Chairman’s Statement.
Cash
The Group’s cash reserves as at 31 March 2023 were £22.26m, 
including short-term cash deposits of £1.22m. This represents 
a reduction of £2.78m from the prior year equivalent date 
(31 March 2022: £25.04m) primarily due to R&D cash spend 
of £5.13m, net share buybacks totalling £3.65m, dividend 
payments of £1.59m and a £0.93m investment in capital 
equipment. Whilst the total net cash inflow from operating 
activities was £5.41m and from investing activities the sale of 
land at £2.50m. 
Inventories
Raised inventory levels have been an intentional element 
of the Group’s approach to addressing semiconductor 
supply chain disruptions that have been a feature in recent 
years and in support of an expanding product range. 
At 31 March 2023, inventories were valued at £2.43m (FY22: 
£2.26m) with 38% being held as raw material (FY22: 39%) and 
the balance either work In progress or as finished goods.
Pension schemes
The Group operates several pension schemes globally, 
mostly of a defined contribution nature. In the UK, the 
Company historically operated a defined benefit scheme 
that was closed to new members on 1 April 2002 and to 
future accruals in 2009. The funding position of this scheme 
improved through the year when calculated under IAS 
19 methodology, with a deficit of £1.20m being recorded 
(2022: £2.44m).
Separately, the most recent actuarial estimate carried out 
by an independent professionally qualified actuary, as at 
31 March 2023 and based upon existing funding principles, 
indicated a net pension surplus with the funding level at 
112%. 2023 is an actuarial valuation year with the formal 
triennial valuation not expected to be published until 
early 2024. 
All administrative expenses of running the scheme are 
met directly by the scheme along with pension protection 
fund levies.

More recently, Environmental concerns have risen to the 
fore and companies are being challenged more and more 
to embrace and act upon policies that reduce the impact 
the business has on the Environment. Similar ethical principles 
apply – CML endeavours to do things responsibly. We are 
committed to an annual improvement process whereby 
we will tell stakeholders what we do and where we are 
addressing relevant areas for improvement.
The Group’s aim is to minimise its environmental impact 
and to implementing environmental best practices where 
appropriate. We conduct our operations in a manner that is 
expected to achieve the following environmental objectives.
•	 Comply with/or exceed the requirements of the 
relevant environmental legislation governing the 
business operations.
•	 To use energy and water resources efficiently for the 
purpose.
•	 Minimise waste production, as far as is reasonable and 
practical, and to control the treatment and disposal of 
waste produced.
During the year, as part of our implementation we:
•	 promoted environmental awareness using 
biodegradable packing materials; and
•	 continued to minimise waste through reuse and 
recycling.
Climate change
We are aware of the ongoing impact of climate change, 
which brings serious environmental, economic and social 
challenges. Technology and innovation play a critical role 
in helping to sustain our planet, address environmental 
challenges, create efficiencies and respond to the needs of 
stakeholders.
We are continually seeking ways to reduce our environmental 
footprint through efficient energy use and responsible use of 
materials. In particular, we are focused on reducing climate 
risks related to our direct climate footprint and the emissions 
from our own operations.

To combat the growth of greenhouse gas (GHG) emissions, 
the Board continues to develop a range of carbon‑reduction 
initiatives to manage global operations effectively and 
efficiently.
We have targeted a series of initiatives to improve energy 
usage, including:
•	 successful installation of solar panels at our UK head 
office at Oval Park, Langford, saving an average 
of 166,000 kWh each year, further installation of 
solar panels is planned for the current year which is 
estimated to save a further 66,000 kWh each year with 
an overall estimated average saving of 232,000 kWh 
each year;
•	 switched to LED lighting at our Langford premises, with 
an estimated energy saving of £15,000; 
•	 successful installation of BMS system has enabled us to 
reduce the run times of our plant through optimisation, 
leading to a usage saving of 104,000 kWh per year; 
and
•	 offering electric vehicle charging at our Langford site 
and providing bike storage across all our UK sites.
We recognise the importance of reporting against Scopes 1 
and 2 emissions and to help improve our carbon accounting 
for Scope 3 emissions in the future, we are committed 
to continuously reviewing our data collection processes 
to become better informed. This will help to reduce the 
upstream and downstream impact of those emissions in 
the future. 
As well as improving efficiency in energy consumption, we 
are also aiming to increase our contribution to the circular 
economy through increased recycling and reducing waste. 
Consumption of water on our sites is low and we have 
extraction rights for use on our land at Langford. Much 
of the waste that we generate is tied to our offices and 
manufacturing facilities.
Resource efficiency
Our facilities are equipped with recycling sites for paper and 
plastic and we encourage the conservation of water and 
other resources. 
We encourage employees to recycle. As a company, 
we ensure all our general waste is sorted into recyclable 
and non-recyclable items by our refuse collectors, where 
it is taken to a materials recovery facility, separated and 
recycled accordingly. We also have dedicated cardboard 
and paper waste collection points. 
At the materials recovery facility, non-recyclable waste is 
shredded and used as refuse-derived fuel. 
Supply chain
We continue to work with suppliers to strengthen our 
supply‑side capabilities as global sustainability challenges 
grow. We are continually assessing our design and 
manufacturing processes to minimise the consumption of 
resources through energy efficiency and reducing waste.

People
Our goal is to cultivate a diverse and respectful work environment 
where employees can thrive and innovate.
We support all our employees with the successful implementation of 
our guiding principles in their daily work, development and training. 
Diversity
For us, the acceptance and inclusion of employees of all 
backgrounds, without discrimination is a key asset since it 
acknowledges the individual strengths of each employee 
and the potential they bring.
Growth (based on FTE)
Our workforce grew by 5% year-on-year, reflecting our 
continual ability to attract high calibre people to the Group 
and retain them.
Within the principles, we have a clear strategic focus on 
strong business ethics, a passion for excellence and listening 
and engaging with our colleagues on improving our ways of 
working, which support the business to drive a more diverse 
and inclusive workplace.
We view the social aspect of running a business as ‘common 
sense’. Simply put, we look after our employees, we pay 
suppliers fairly and we focus on the long term. If we did not, 
then we would not have a sustainable business. We also 
try to play an active role by supporting organisations that 
benefit the local community. We did not have a name for 
that before – now it is the ‘S’ in the Environmental, Social and 
Governance (ESG) agenda.
Human capital
We continue to build a safe working environment to attract 
and retain a skilled global workforce that is diverse and 
inclusive, helping to drive innovation and sustainability.

Employee health, safety and wellness
Employee wellbeing remains an important focus for the 
Group and the health and wellbeing of staff make a 
vital contribution to sustained success, evidenced by 
our low rates of work-related ill health, low staff turnover 
and staff absences. The Group recorded no work-related 
fatalities and a low incidence of lost time due to injury and 
absenteeism.
During 2023, we had two minor incidents and no significant 
injuries across all our businesses. All incidents are followed up 
with changes to procedures and/or training of our employees 
as appropriate to prevent recurrence.
Cost-of-living crisis
During 2023, a cost-of-living crisis has been triggered due 
to the combined impact of COVID-19 and the various 
economic effects of the Russian invasion of Ukraine. 
During these uncertain times, the Group has supported 
employees globally through a mixture of salary increases 
and cost-of-living payments.
Development and training
We are committed to enhancing our human capital through 
excellent recruitment, staff retention, succession planning 
and staff development.
Valuing and enhancing the development of employees is 
important and we encourage the training of all employees to 
maintain high professional standards and inspire innovation, 
and we support them in developing their individual skills.
We are developing our initiatives to enhance and record 
staff training and development programmes focusing on 
management development and approaches. 
Environment, social and governance continued
Staff benefits
Various benefits in relation to pensions and healthcare in line with local employment standards are offered to employees.
Following a Company-wide review during the year, our employees continue to be paid above the National Living Wage 
and we follow local and national minimum wage values globally.
Workforce inclusion
As a Group, we encourage people from all backgrounds to thrive and achieve their full potential. We understand that 
inclusivity should be included in everyday practice and encourage employees to be curious, communicate and learn 
from others. 
Our work environment is a place where everyone can thrive without discrimination or harassment. We offer a supportive 
environment, with a diverse workforce, whom we support and listen to.
Providing an excellent workplace is evidenced through employees having long staff tenure and low staff turnover.
Our average length of service is 19 years, with 43% of our team having worked for our businesses for more than ten years.
Staff turnover has always been low and in 2023 was 6.67% of our workforce, below the UK average. We calculate this 
figure as the number of leavers in the year (excluding any retirements) divided by the average annual number of staff.

Prosperity
Sustainability not only creates opportunities in the application of our products that provide 
critical solutions for environmental or social impact, but also in the way we do business and 
interact with our employees, suppliers, communities and wider society.
Innovation
Technical innovation is a strategic pillar and is a fundamental 
contributor to the Group’s success. 
Digital technology trends are transforming the world at an 
accelerated pace and communication and connectivity 
will be fuelled by, amongst other things, 5G adoption. These 
trends are the building blocks for an increasingly smart and 
connected world.
CML requires constant innovation in order to respond to 
changes in market fundamentals and wider society. This 
innovation is also fostered through diverse perspectives 
and is imperative for value creation, for the benefit of all 
stakeholders.
Successful innovation through research and development 
(R&D) is the heart of our business, leading to new products 
and improvements to existing ones, which we seek to protect 
through our intellectual property (IP). CML continues to make 
significant investments in R&D. 
Our IP portfolio includes patents, copyrights, trademarks and 
other rights within professional and industrial voice and data 
communications products.

Giving back to communities
Trust and respect are part of the Company’s core values 
and we value the importance of giving back to our local 
communities. 
We encourage our employees to support charitable causes 
and make an impact within the communities by aiming to 
foster a sense of local and social inclusivity. Being based in a 
community environment, we aim to help local communities 
and support groups as much as possible.
We continue to offer our support where we believe a 
difference can be made but are aware that there is 
always room for improvement and the possibility to offer 
more support.
Collaboration
We are collaborating with others to influence 
industry‑wide improvements.
We are proud to be members of the International Association 
of Marine Aids to Navigation and Lighthouse Authorities 
(IALA) the Digital Radio Mondiale (DRM) Consortium and the 
European Telecommunications Standards Institute (ETSI).
IALA encourages its members to 
work together in a common effort to 
harmonise Marine Aids to Navigation 
worldwide and to ensure that the 
movements of vessels are safe, 
expeditious and cost-effective while 
protecting the environment.
DRM is the universal, openly 
standardised digital broadcasting 
system for all broadcasting 
frequencies. DRM digital radio can 
save broadcasters up to 80% in energy 
and maintenance costs.
Several Group employees sit on 
technical committees that form ETSI, 
a European Standards Organization 
(ESO), which is recognised as the 
regional standards body dealing with 
telecommunications, broadcasting 
and other electronic communications 
networks and services.
Local community and government
As part of our ongoing engagement and discussion with the 
local community, we have been engaged with Langford 
and Ulting Parish Council and Maldon District Council for the 
redevelopment of Oval Park. 
With the granted planning permission we believe that Oval 
Park will provide a significant economic impact to the 
Maldon District, the transformation of the brownfield site will 
bring jobs to the area along with the relocation of two world 
leading organisations.

Greenhouse gas reporting methodology
The above greenhouse gas emissions data is reported using an operational control approach to define our organisational boundary, which meets the definitional requirements of the 
regulations in respect of those emissions for which we are responsible; Scope 1 being emissions from combustion of fuel and refrigerant gas losses, and Scope 2 being electricity (from 
location‑based calculations), heat, steam and cooling purchased for the Group’s own use. This includes all material emission sources which we deem ourselves to be responsible for. Scope 3 
has not been reported upon as this is not applicable to our Group. 
The tables above demonstrate that absolute emissions have decreased by 30.16%; the Group continues to review its carbon footprint and introduce measures to reduce this going forward.

Section 172 statement
We believe that effective 
engagement with our 
stakeholders is fundamental to 
maximising value and securing 
our long‑term success.
Section 172 of the Companies Act 2006
The Board acknowledges that there is a legal 
requirement for the Company to report on 
how the Board and its Committees have 
considered the requirements of Section 
172 of the Companies Act 2006 in their 
decision‑making.
We set out our key stakeholder groups, their 
material issues and how we engage with 
them. Each stakeholder group requires a 
tailored engagement approach to foster 
effective long-term success and maintain 
mutually beneficial relationships.
Our strategy has identified addressable 
markets, including a number of key growth 
areas such as critical infrastructure (public 
utilities, smart grid, RFID), 5G (repeaters, 
small/picocells, fixed wireless access, 
distributed antenna systems) and satellite 
communications (terminals, broadband 
access). As a result, the Group’s annual 
addressable market has increased 
substantially and the Group’s return on 
investment (ROI) profile relating to R&D 
expenditure is evolving as the full benefit 
of the expanded strategy and related 
performance enhancements take hold. 
Overall, the Group’s resulting ROI profile is now 
a “blended” approach, improving the timing 
for a return on the investments being made.

Corporate governance statement
Introduction
In this statement we explain the key features of the Group’s corporate governance framework and how it complies with the ten principles of the QCA Code.
01.
Establish a strategy and business model 
which promote long-term value for 
shareholders
The Group’s vision is to be the first-choice semiconductor partner to technology innovators, together transforming how the world communicates.
The focus is on our customers’ success by delivering advantages through the improved functionality and performance of class-leading IC solutions. R&D activity 
is targeted at developing the product portfolio to support emerging and evolving customer requirements for size, cost and performance whilst striving to remain 
our customers’ first-choice supplier within their advanced communication platforms.
Continued investment in growth development across all markets with a clear pipeline of future products and business opportunities to drive organic growth.
02.
Seek to understand and meet 
shareholders’ needs and expectations
The Group Managing Director is the principal spokesperson for engagement with shareholders. The Executive Chairman is present at interim and full-year 
briefings and is otherwise available to discuss any matters of concern with shareholders and stakeholders alike. Communication is with all shareholders, 
including investors, fund managers, the media and other interested parties. Briefings are held with investors and analysts following the announcement of 
half‑year and preliminary results along with other ad-hoc meetings throughout the year.
03. 
Take into account wider stakeholder 
and social responsibilities and their 
implications for long-term success
By understanding our stakeholders, the Board can discuss the potential impact of our decisions on each group, ensuring that we consider their needs and concerns.
The Company’s key stakeholder groups are:
•	 shareholders;
•	 employees;
•	 customers;
•	 suppliers; and
•	 local government and communities.
Shareholders: We engage with shareholders through our reports, regular news releases, website, Annual General Meeting, investor presentations and 
one‑on‑one meetings.
Employees: We have an open, collaborative and inclusive structure and engage regularly with our employees. We try to foster a suitable environment to allow 
them to realise their full potential.
Customers: We work closely with our customers to develop a deep understanding of their business, giving us the ability to anticipate and respond to their 
needs and foster long-term relationships.
Suppliers: We engage with our suppliers regularly to ensure our quality and commercial objectives are met. We strive to maintain continuity of supply through 
varying global economic and market conditions.
Local government and communities: We attend a variety of regional business meetings throughout the year and attend council events linked to the local 
community and work with local educational establishments and offer funding for research projects.
Social responsibility: As a Board, our intention is to behave responsibly and to ensure that management operate the business in a responsible manner, 
operating with high standards of business conduct and good governance that reflects our responsible behaviour, and our shareholders will benefit from the 
delivery of the long-term plan.
04. 
Embed effective risk management, 
considering both opportunities and 
threats, throughout the organisation
The Board has established Audit and Remuneration Committees and, as part of its leadership and control of the Company, the Board has specific items 
reserved for its consideration which include business strategy, financial performance, acquisitions, divestments and major capital investment.
The Audit Committee is responsible for ensuring the financial performance of the Group is properly measured and reported, and for reviewing reports from 
auditors relating to the Group accounts and the Group’s internal control systems.

05.
Maintain the Board as a 
well‑functioning, balanced team 
lead by the chair
The Group is led and controlled by an effective and entrepreneurial Board that comprises two Executive Directors and two Non‑Executive Directors. 
The Executive Chairman is primarily responsible for the running of the Board and the Group Managing Director is the Chief Operating Decision Maker with 
responsibility for the day‑to‑day running of the Group and for implementing Group strategy. 
The Board’s activities are supported by its Nomination, Audit and Remuneration Committees.
The Board and its Committees receive high quality, accurate and timely information on a regular basis. The Board meets formally a minimum of four times per year.
All the Directors have appropriate skills and experience for the roles they perform at the Company, including as members of Board Committees. All Directors 
are subject to re‑appointment at the first AGM after their appointment and, thereafter, apart from the Group Managing Director, one‑third of the remaining 
Directors shall retire by rotation at the AGM.
The Company is satisfied that the current Board is sufficiently resourced to discharge its governance obligations on behalf of all stakeholders and will consider 
the requirement for additional Executive and Non-Executive Directors as the Company fulfils its growth objectives.
Board meetings: The Board meets against a defined reporting timetable and at times in between the scheduled meetings when required. The Board meets 
formally a minimum of four times per year. During the year ended 31 March 2023, twelve Board meetings were held where all Directors in post participated 
(2022: 15).
06.
Ensure that between them the Directors 
have the necessary up-to‑date 
experience, skills and capabilities
The evaluation of the Board, collective skills and its performance, along with that of the individual members, is considered on an ongoing basis considering 
the needs of the Company and its stakeholders. New appointments are led by the Group Managing Director and considered by the whole Board acting as 
the Nominations Committee.
07.
Evaluate the Board performance based 
on clear and relevant objectives, 
seeking continuous improvement
The Board evaluates its own performance regularly. Annually the Remuneration Committee evaluates performance as part of the review of remuneration and 
discretionary bonus awards.
The Board and the Remuneration Committee evaluate the Board performance, including, but not limited to, collective skills. Its performance along with that of 
the individual members is considered on an ongoing basis considering the needs of the Company.

Promote a corporate culture that 
is based on ethical values and 
behaviours
The Board along with the Senior Management team define the core Vision, Values and Guiding Principles of CML Microsystems Plc which supports the 
objectives of the Company.
09.
Maintain governance structures and 
processes that are fit for purpose and 
support good decision-making by 
the Board
The Company’s Corporate Governance Statement as set out in its 2023 Annual Report and Accounts explains the structures which are in place at Board and 
Committee level and how these interact, including the roles individual Directors fulfil on the Board.
The organisational structure is kept under continual review and evolves as the needs of the business change to fulfil its growth objectives.
Although the Board delegates some matters to its Committees (Remuneration and Audit), as part of its leadership and control of the Company, the Board has 
specific items reserved for its consideration which include business strategy, financial performance, acquisitions, divestments and major capital expenditure.

Introduction
This report has been voluntarily prepared in accordance with the regulations regarding 
Directors’ remuneration report. As in previous years, the shareholders will be asked to approve 
the Directors’ Remuneration Report at the forthcoming AGM of the Company at which the 
financial statements will be approved. Approval sought for this will have advisory status. The 
remuneration policy as set out in this report is considered at each AGM and voted upon by 
the shareholders. There are no changes deemed necessary to the current arrangements. 
There has been no change in remuneration policy during 2023.
Consideration of employment conditions elsewhere in the Group
In setting the policy for Directors, the Remuneration Committee is mindful of the Group’s 
objective to reward all employees fairly according to their role, experience and performance. 
In setting the policy for Directors’ remuneration, the Committee considers the pay and 
employment conditions of the other employees within the Group. No formal consultation has 
been undertaken with the Group’s employees in drawing up this policy.
The Committee has not used formal comparison measures.
Directors’ remuneration report
Remuneration Committee
The Board has established a Remuneration Committee that currently comprises Nigel Clark 
(Committee Chairman), Geoff Barnes and Chris Gurry. The Board acknowledge that it is a 
departure from the QCA code for Executives to be members of the Committee. No member 
of the Remuneration Committee participates in deciding their personal remuneration 
package. During the year ended 31 March 2023, there was one meeting (2022: two 
meetings) where all Directors in post participated.
Remuneration policy
Set out in the following table is the Group’s policy on Directors’ remuneration. In setting the 
policy, the Remuneration Committee has taken into account:
•	 the need to attract, retain and motivate individuals of a calibre who will ensure 
successful leadership and management of the Company;
•	 the Group’s general aim in seeking to reward all employees fairly according to the 
nature of their role;
•	 the need to align the interests of the shareholders as a whole with the long‑term growth 
of the Group;
•	 the need to be flexible and adjust with operational changes throughout the term of this 
policy;
•	 the size and nature of the business; and
•	 knowledge of general pay levels within the Company’s peer group and similarly sized 
companies.
The Committee takes into account the pay and employment conditions of the wider 
employee population across the Company when setting Executive Director remuneration 
and considered that as context when reviewing the policy. While the Committee has 
not consulted employees directly in the remuneration policy for Executive Directors, the 
Committee is made aware of information such as workforce demographics, diversity 
initiatives, training programmes, engagement levels and cultural initiatives, as well as the 
remuneration principles and policies that apply to the wider workforce. It is expected that 
future salary increases for Executive Directors will be in line with the general employee 
population, except in exceptional circumstances.
The remuneration of the Non‑Executive Directors is determined by the Board and takes into 
account additional remuneration for services outside the scope of the ordinary duties of 
Non‑Executive Directors.

The Company has no long‑term incentive plans for Directors and no separate share option scheme exists solely for Executive Directors; therefore, they only participate in share option plans 
that are eligible to all employees. The Committee believes that share option schemes for all employees maximise shareholder value over time and therefore no specific performance 
conditions attach to the number of options granted to Executive Directors on an individual basis.

Policy on payment for loss of office
There are no contractual provisions that could impact on a termination payment. Termination 
payments will be calculated in accordance with the existing contract of employment 
or service contract. It is the policy of the Remuneration Committee to issue employment 
contracts to Executive Directors with normal commercial terms and without extended terms 
of notice which could give rise to an extraordinary termination payment.
Directors’ service contracts
Chris Gurry is employed by the Company under a written contract of employment that 
provides for termination by either party giving twelve months’ notice. Nigel Clark is employed 
by the Company under a written service contract that provides for termination by either party 
giving six months’ notice.
Jim Lindop has a service contract effective from 1 April 2022 and Geoff Barnes has a service 
contract effective from 1 April 2021. All Directors are subject to re‑appointment at the first 
AGM after their appointment and, thereafter, apart from the Group Managing Director, 
one‑third of the remaining Directors retire by rotation at the AGM in line with the Company’s 
Articles of Association.
Directors’ notice periods are set in line with market practice and of a length considered 
sufficient to ensure an effective handover of duties should a Director leave the Company.
Approach to recruitment remuneration
All appointments to the Board are made on merit. The components of the remuneration 
package (for a new Director recruited within the life of the approved remuneration policy) 
would comprise of a base salary, pension, benefits, annual bonus and an opportunity to be 
granted share options. The approach with any appointment is detailed in the policy table. 
The Company aims to attract appropriately skilled and experienced individuals offering a 
level of remuneration that, in the opinion of the Remuneration Committee, is not excessive 
but fair.
Consideration of shareholder views
No shareholder views have been taken into account when formulating this policy. In 
accordance with the regulations, an ordinary resolution for approval of this policy will be put 
to the shareholders at the AGM on 9 August 2023.
This section of the Directors’ Remuneration Report sets out the remuneration paid in 2023 and 
the proposed remuneration for 2024. This section will be put to an advisory shareholder vote 
at the 2023 AGM. During the year, the remuneration policy operated as intended. Sections

Share options (audited) continued
Depending on the share option scheme, options are granted at an exercise price not less

Directors’ report
The Directors submit their report and Group financial 
statements for the year ended 31 March 2023 in addition to 
the Directors’ Remuneration Report on pages 40 to 46. 
The Directors referred to on page 34 all served throughout the 
year ended 31 March 2023.
Corporate governance statement 
The Group follows the Quoted Companies Alliance 
Corporate Governance Code 2018 (the “Code”), 
details of which can be found on pages 36 to 39.
Going concern
The Group’s business activities, performance, position and 
risks are set out in this Annual Report and Accounts. The 
financial position of the Group, its cash flows, liquidity position, 
borrowing facilities and the use of financial instruments and 
policies relating thereto are detailed in the notes to the 
financial statements. The report also includes details of the 
Group’s risk mitigation and management.
Given the nature of the markets we operate within, 
we anticipate our end customers being insulated from a 
consumer downturn to some extent, although the roll-out 
of some of the new products may be delayed, dampening 
demand for our semiconductors. Even in these difficult times, 
we still maintain the belief that the Group is well placed to 
move positively forward in the medium to long term. This 
belief is underpinned by a strong balance sheet and no debt, 
along with a product portfolio that addresses markets that 
have a positive outlook.
After making enquiries, the Directors have a reasonable 
expectation that the Company and the Group have 
adequate resources to continue in operational existence for 
the foreseeable future. Accordingly, they continue to adopt 
the going concern basis in preparing the Annual Report and 
Accounts.
Principal activities
The Group designs, manufactures and markets a range of 
semiconductor products for use in global communications 
industries.
Business review and future developments
The Strategic Report on pages 01 to 32 provides an analysis of 
the business of the Group along with the development and 
performance of the business during the year and the position 
at the year end along with future developments. A range of 
performance measures to monitor and manage the business 
are discussed within the Strategic Report on page 11.
The Group’s business activities, performance, position 
and risks are set out in this Annual Report and Accounts. 
The financial position of the Group, its cash flows, liquidity 
position, borrowing facilities and the use of financial 
instruments and policies relating thereto are detailed in the 
notes to the financial statements. The report also includes 
details of the Group’s risk mitigation and management.
Results
The results for the Group for the current and comparative 
periods are discussed in the Financial Review section of 
the Group Managing Director’s Review within the Strategic 
Report, as required by legislation.
Dividends
An interim dividend of 5p per 5p ordinary share was paid 
on 16 December 2022 to shareholders on the Register on 
2 December 2022.
The Directors are proposing to pay a final dividend of 6p 
per 5p ordinary share, taking the total dividend amount in 
respect of the year ended 31 March 2023 to 11p (2022: 9p 
total dividends). 
Post balance sheet events
In April 2023 the Company put in place a share buyback 
programme of £1,750,000 for the principal purpose of 
reducing the issued share capital of the Company.
On 17 January 2023, CML Microsystems Plc entered into 
a definitive agreement to acquire a Silicon Valley based 
semiconductor company, Microwave Technology, Inc (MwT), 
which is subject to US regulatory clearance process. 
Research and development
The Group actively reviews developments in its markets with 
a view to taking advantage of the opportunities available 
to maintain and improve its competitive position. This action 
involves the design and development of hardware and 
firmware for the semiconductor environment.
Strategic Report
Greenhouse gas emissions, energy consumption and energy 
efficiency are detailed in the Environment, social and 
governance section on page 29 and future developments 
in the Group Managing Director’s Review on page 13. 
In accordance with Section 414C (11) of the Companies 
Act 2006, these have been included in the Strategic Report.

Significant agreements – change of control
There are no agreements to which the Company is party that take effect, alter or terminate 
upon a change of control of the Company following a takeover bid, other than Director 
share options.
Payment of payables
It is the Company’s policy to negotiate payment terms with its suppliers in all sectors and 
to ensure that they know the terms on which payment will take place when the business is 
agreed. It is our policy to abide by these terms. The Company is not a trading entity and as 
such has no trade payables outstanding at the end of the financial year; the Company’s 
practice in respect of the year with regard to its payment of creditors has been 30 days 
(2022: 30 days). The Group’s general policy is to pay all creditors in a period between 
30 and 45 days.

The above interests in the ordinary share capital of the Company are beneficial. Details of 
the Directors’ interests in options granted over ordinary shares are disclosed in the Directors’ 
Remuneration Report. There have been no changes in the Directors’ interests in shares 
between 1 April 2023 and 20 June 2023. With the exception of Directors’ service contracts, 
there are no contracts of significance in which the Directors have an interest.
Third-party indemnity provision for Directors
The Company currently has in place and has done for the whole of the year ended 
31 March 2023, Directors’ and officers’ liability insurance for the benefit of all Directors of 
the Company.
Annual General Meeting
The notice of the Annual General Meeting sets forth resolutions for the customary ordinary 
business resolutions 1 to 7 and special business comprising one ordinary resolution 8 and three 
special resolutions, 9, 10 and 11, relating to the following matters:
Special business ordinary resolutions
•	 To renew the authority for the Company to allot relevant securities.
Special business special resolutions
•	 To disapply the pre‑emption provisions of the Companies Act 2006.
•	 To disapply the pre-emption provisions of the Companies Act 2006 for the purposes of 
financing an acquisition or capital investment. The Prospectus Rules were amended in 
July 2017 whereby a Prospectus is not required for additional shares being issued as part of 
an acquisition where those shares are below 20% of the total equity holding less treasury 
shares. Accordingly, the numbers in this resolution are revised to provide for the additional 
flexibility afforded by this amendment.
•	 To renew the authority to the Company to make market purchases of its own shares.
Capital risk management
The Company only has one class of share, as detailed in note 27. Although no specific 
basis, such as the gearing ratio, is used to monitor the capital, the Group’s objectives when 
managing capital are to safeguard the Group’s ability to continue as a going concern in 
order to provide returns for shareholders and benefits for other stakeholders.
In order to maintain or adjust the capital structure, the Group may adjust the amount of 
dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets to 
reduce debt.

Internal control and risk management systems in relation to the process 
of preparing consolidated accounts
The Board has delegated to the Audit Committee the responsibility for monitoring the 
effectiveness of the systems of risk management and for overseeing the system of internal 
controls to ensure these are appropriate to the business environments in which the Company 
operates. 
The elements of the internal control system are aimed at ensuring the accuracy and reliability 
of consolidated financial reporting and guarantee that business transactions are recognised 
in full and at the proper time in accordance with statutory regulations and CML Microsystems 
Plc’s Articles of Association. Furthermore, they ensure that inventory counts are carried out 
correctly and that assets and liabilities are accurately recognised, measured and disclosed 
in the consolidated financial statements. The systems also ensure that the accounting 
documents provide reliable, comprehensible information.
The controlling activities to ensure the accuracy and reliability of the accounting include 
analytical reviews as well as the execution and control of important and complex 
transactions by different people. The separation of administrative, executive, accounting 
and authorisation functions and their performance by different individuals (dual signatures) 
reduces the risk of fraud.
Internal guidelines also govern specific formal requirements made of the consolidated 
financial statements. Establishing the group of consolidated companies is defined in detail, 
as are the components of the reports to be drawn up by the Group companies and their 
transmission to the central consolidation system. 
The formal requirements relate to the mandatory use of a standardised and complete set of 
reporting forms and a uniform account framework for the Group. The internal guidelines also 
include concrete instructions on presenting and carrying out netting procedures within the 
Group and confirming the resulting account balances.
At Group level the specific control activities to ensure the accuracy and reliability of 
consolidated financial reporting include the analysis and, if necessary, restatement of 
separate financial statements prepared by Group companies, taking into account the 
auditor’s report and meetings held to discuss them. 
Statement as to disclosure of information to the auditor
The Directors who were in office on the date of approval of these financial statements have 
confirmed that, as far as they are aware, there is no relevant audit information of which the 
auditor is unaware.
Each of the Directors have confirmed that they have taken all the steps that they believe they 
ought to have taken as Directors in order to make themselves aware of any relevant audit 
information and to establish that it has been communicated to the auditor.
Auditor
A resolution to re-appoint BDO LLP, as auditor of the Company will be put to the members at 
the forthcoming Annual General Meeting.

Directors’ report
Financial statements
Other information

The Directors are responsible for preparing the Annual Report 
and the financial statements in accordance with applicable law 
and regulations. 
Statement of Directors’ responsibilities 
in respect of the financial statements
Company law requires the Directors to prepare financial statements for each financial year. 
Under that law the Directors are required to prepare the Group and Company financial 
statements in accordance with UK adopted international accounting standards. Under 
company law the Directors must not approve the financial statements unless they are satisfied 
that they give a true and fair view of the state of affairs of the Group and Company and of 
the profit or loss of the Group for that period. 
In preparing these financial statements, the Directors are required to:
•	 select suitable accounting policies and then apply them consistently;
•	 make judgements and accounting estimates that are reasonable and prudent;
•	 state whether they have been prepared in accordance with UK adopted international 
accounting standards subject to any material departures disclosed and explained in the 
financial statements; and
•	 prepare the financial statements on the going concern basis unless it is inappropriate to 
presume that the Group and the Company will continue in business.
The Directors are responsible for keeping adequate accounting records that are sufficient 
to show and explain the Company’s transactions and disclose with reasonable accuracy 
at any time the financial position of the Company and enable them to ensure that the 
financial statements comply with the requirements of the Companies Act 2006. They are also 
responsible for safeguarding the assets of the Company and hence for taking reasonable 
steps for the prevention and detection of fraud and other irregularities.
Website publication
The Directors are responsible for ensuring the Annual Report and the financial statements

Opinion on the financial statements
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 March 2023 and of the Group’s profit for the year then 
ended;
•	 the Group financial statements have been properly prepared in accordance with UK 
adopted international accounting standards;
•	 the Parent Company financial statements have been properly prepared in accordance 
with UK adopted international accounting standards and as applied in accordance with 
the provisions of the Companies Act 2006; and
•	 the financial statements have been prepared in accordance with the requirements of the 
Companies Act 2006.
We have audited the financial statements of CML Microsystems Plc (the ‘Parent Company’) 
and its subsidiaries (the ‘Group’) for the year ended 31 March 2023 which comprise the 
Consolidated income statement, the Consolidated statement of total comprehensive 
income, the Consolidated statement of financial position, the Consolidated and Company 
cash flow statements, the Consolidated statement of changes in equity, the Company 
statement of financial position, the Company statement of changes in equity and notes to 
the financial statements, including a summary of significant accounting policies. The financial 
reporting framework that has been applied in their preparation is applicable law and UK 
adopted international accounting standards and, as regards the Parent Company financial 
statements, as applied in accordance with the provisions of the Companies Act 2006.
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 believe that the audit evidence we have obtained is sufficient and appropriate to 
provide a basis for our opinion. 
Independence
We remain independent of the Group and the Parent Company in accordance with the 
ethical requirements that are relevant to our audit of the financial statements in the UK, 
including the FRC’s Ethical Standard as applied to listed entities, and we have fulfilled our 
other ethical responsibilities in accordance with these requirements. 
Conclusions relating to going concern
In auditing the financial statements, we have concluded that the Directors’ use of the going 
concern basis of accounting in the preparation of the financial statements is appropriate. 
Our evaluation of the Directors’ assessment of the Group and the Parent Company’s ability to 
continue to adopt the going concern basis of accounting included:
•	 Obtaining the Directors’ cash flow forecasts and evaluating the key assumptions in respect 
of revenue growth, gross profit margins, cash generation and the potential impact of key 
provisions with reference to our knowledge of the business, its historical performance and 
results;
•	 Checking the mathematical accuracy of forecasts and critically assessing the integrity of 
the forecast model by analysing the assumptions and data verifying the information to 
supporting documentation, along with confirming its consistency with approved forecasts;
•	 Evaluating sensitivity analysis and reverse stress tests prepared by the Directors in relation to 
the Group’s cash flow forecasts by checking that the stress tests left the Parent Company 
and Group in a positive cash position whilst considering the likelihood of the stressed 
scenarios occurring. The analysis considered reasonably possible adverse effects that 
could arise as well as a stress test to consider the level of future revenue reduction the 
Group could support; and
•	 Considering the adequacy of disclosures in the financial statements to check they are in 
accordance with the directors going concern assessment.
Based on the work we have performed, we have not identified any material uncertainties 
relating to events or conditions that, individually or collectively, may cast significant doubt on 
the Group and the Parent Company’s ability to continue as a going concern for a period of 
at least twelve months from when the financial statements are authorised for issue. 
Our responsibilities and the responsibilities of the Directors with respect to going concern are 
described in the relevant sections of this report.

(2022: 5% of Profit before tax)
An overview of the scope of our audit
Our Group audit was scoped by obtaining an understanding of the Group and its 
environment, including the Group’s system of internal control, and assessing the risks of 
material misstatement in the financial statements. We also addressed the risk of management 
override of internal controls, including assessing whether there was evidence of bias by the 
Directors that may have represented a risk of material misstatement.
The Group operates through a number of legal entities, which form reporting components, 
consistent with those included in Note 18. CML Microsystems Plc, CML Microcircuits UK Limited, 
and Wuxi Sicomm Technologies, Inc are significant components and were subject to full 
scope audits. 
The audit of Wuxi Sicomm Technologies, Inc. included the audit of its subsidiary entity, 
Shanghai Futiake Investment Consulting Co., Ltd which is a non-significant component. 
CML Microcircuits (USA) Inc. and CML Microcircuits (Singapore) Pte Limited also constitute 
significant components. Balances and transactions have been audited to component 
materiality as the entities were considered part of the same significant component that 
contains CML Microcircuits (UK) Limited due to the trading relationship between the 
entities. PRFI Limited was considered to be a non-significant component and was subject 
to desktop review procedures. All audits and desktop review procedures were completed 
by BDO LLP except for the audit and agreed upon procedures of the sub-group headed 
by Wuxi Sicomm Technologies, Inc., which was completed by non-BDO member firm local 
component auditors. 
Our involvement with component auditors
For the work performed by component auditors, we determined the level of involvement 
needed in order to be able to conclude whether sufficient appropriate audit evidence has 
been obtained as a basis for our opinion on the Group financial statements as a whole. 
Our involvement with component auditors included the following:
•	 Audit scoping and planning meeting with local component auditors held remotely; 
•	 Provision of group engagement instructions for the year ending 31 December 2022, 
being the component financial year end, containing information on the significant risks 
at group and component level, materiality calculations, summary of significant audit and 
accounting issues, specific procedures and communications required and considerations 
in respect of laws and regulations, fraud and irregularities;
•	 Provision of agreed upon procedures to be performed by the component auditors 
covering the period from 1 January 2023 to 31 March 2023 and as at 31 March 2023;
•	 Remotely attending audit progress meeting with local component auditors;
•	 Review of group reporting information provided;
•	 Remote review of component auditors audit file and results of agreed upon procedures 
performed; and
•	 Remotely attending audit completion meeting with local component auditors.
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, including those which had the greatest effect on: the overall audit strategy, 
the allocation of resources in the audit, and directing the efforts of the engagement team. 
These matters were addressed in the context of our audit of the financial statements as a 
whole, and in forming our opinion thereon, and we do not provide a separate opinion on 
these matters.

Key audit matter 
How the scope of our audit addressed the key audit matter
Intangible assets – 
Capitalised development 
costs 
The group’s accounting 
policy is described in note 
1f with information relating 
to critical accounting 
judgements being given 
in 1r. Further analysis of the 
Group’s development costs is 
included in note 15 
The Group has significant amounts 
capitalised as development costs as it 
has continued to develop its product 
portfolio. There is a risk over whether 
costs have been correctly capitalised in 
accordance with accounting standards 
and there is a degree of Management 
judgement involved in determining the 
appropriate point at which costs can 
be determined as development costs 
as opposed to research costs. Further 
to this, there is a risk that the internally 
generated intangibles useful economic 
life is inappropriate.
We considered this to be a key 
audit matter due to the volume of 
expenditure and judgement involved as 
noted above. 
Our audit procedures included the following: 
•	 Reviewing management’s Review of Accounting Treatment for Research and Development Costs workpaper against the key 
criteria of IAS 38 Intangible Assets with regards to the capitalisation of internally generated intangible assets and scrutinising 
management’s accounting policies regarding the capitalisation of development costs and the useful economic life over 
which they are amortised.
•	 Holding discussions with management and other key members of staff outside of the finance team to gain an understanding 
as to what products are being developed. 
•	 Obtaining an understanding of the internal costs that are being capitalised and assessing whether these are in line with 
IAS 38, specifically considering the percentage at which payroll costs are being capitalised and whether this percentage is 
appropriate based on their job role and actual work performed on a daily basis.
•	 Agreeing a sample of employees whose payroll costs have been capitalised back to underlying employment contract, 
checking the job description is consistent with a systems or test engineer.
•	 Assessing the key assumption that a percentage of costs incurred by each cost centre should be capitalised by tracing 
a sample of these costs back to supporting documentation and checking that it was appropriate to capitalize these in 
accordance with the requirements of the applicable accounting standards. 
•	 Critically assessing the key assumption that the development costs should be amortised over a period of six years from when 
the product is in use by reviewing management’s assessment of the useful economic life together with the revenue generation 
profile for a sample of products.
Key observations:
Based on the procedures performed, we found management’s judgements and estimates used in the capitalisation of 
development costs to be appropriate and in line with the requirements of IAS 38.
Carrying value of goodwill
The group’s accounting 
policy is described in note 1e 
with information relating to 
the key sources of estimation 
uncertainty being given in 
1r. Further analysis of the 
Group’s goodwill is included 
in note 13. 
The Group has recognised £7.429m 
in respect of goodwill arising on 
consolidation. 
Management and the Board are 
required to perform an impairment 
review which would indicate whether 
the carrying value of the goodwill 
at 31 March 2023 is impaired. 
Management is required to include 
appropriate disclosure in the financial 
statements in relation to key estimates 
and judgements. 
Due to the materiality of the goodwill 
and the sensitivity of the inputs into the 
impairment review we considered this 
to be a key audit matter.
Our audit procedures included evaluating Management’s impairment assessment. In doing so, our procedures included 
the following:
•	 Assessing the integrity of the model by considering whether the methodology applied in the annual impairment testing was 
consistent with the requirements of accounting standards.
•	 Reviewing management’s impairment assessment based on our knowledge of the Group’s business, performance to date 
and from discussions with management. 
•	 Reviewing and challenging the assumptions underpinning the forecasts and the other inputs into the value‑in-use model, 
including considering the historical accuracy of previous forecasts. This included assessing the appropriateness of the discount 
rate applied, which was done with the assistance of our internal valuations experts, as well as revenue growth rates, expected 
profit margins and terminal value;
•	 Assessing the appropriateness of the different scenarios used by management in assessing of the recoverability of goodwill;
•	 Performing our own sensitivity analysis in respect of discount rates and revenue growth rates using this to challenge 
Management’s sensitivity assessments, as well as comparing the related disclosures to the relevant accounting standards.
Key observations:
We found Management’s conclusion that the goodwill is not impaired at 31 March 2023 to be acceptable and the impact 
of sensitivities appropriately disclosed.

Our application of materiality
We apply the concept of materiality both in planning and performing our audit, and in evaluating the effect of misstatements. We consider materiality to be the magnitude by which 
misstatements, including omissions, could influence the economic decisions of reasonable users that are taken on the basis of the financial statements. 
In order to reduce to an appropriately low level the probability that any misstatements exceed materiality, we use a lower materiality level, performance materiality, to determine the extent 
of testing needed. Importantly, misstatements below these levels will not necessarily be evaluated as immaterial as we also take account of the nature of identified misstatements, and the 
particular circumstances of their occurrence, when evaluating their effect on the financial statements as a whole. 
Based on our professional judgement, we determined materiality for the financial statements as a whole and performance materiality as follows:

Rationale for the

Adjusted profit before tax is 
considered an appropriate 
benchmark as it is the key 
performance measure used by 
stakeholders to assess the Group’s 
performance. We have excluded the 
exceptional items relating to the profit 
on sale of land as this is a transaction 
outside the normal course of business. 
We consider the use of profit before 
tax to be the most appropriate 
benchmark as this is a key 
statutory performance measure 
for stakeholders based on market 
practice and investor expectations 
and is reflective of the changing 
market sentiment in respect of 
alternate performance measures.

Group materiality for Group reporting

Our application of materiality continued
Component materiality
For the purposes of our Group audit opinion, we set materiality for each significant 
component of the Group based on a percentage of between 33% and 95% (2022: 64% and 
95%) of Group materiality dependent on the size and our assessment of the risk of material 
misstatement of that component. Component materiality ranged from £51,000 to £147,000 
(2022: £55,000 to £81,000). In the audit of each component, we further applied performance 
materiality levels of 65% (2022: 60%) of the component materiality to our testing to ensure that 
the risk of errors exceeding component materiality was appropriately mitigated.
Reporting threshold 
We agreed with the Audit Committee that we would report to them all individual audit 
differences in excess of £2,900 (2022: £1,700). We also agreed to report differences below this 
threshold that, in our view, warranted reporting on qualitative grounds.
Other information
The directors are responsible for the other information. The other information comprises the 
information included in the Annual Report and Accounts 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 course of the audit, or 
otherwise appears to be materially misstated. If we identify such material inconsistencies or 
apparent material misstatements, we are required to determine whether this gives rise to a 
material misstatement in the financial statements themselves. If, based on the work we have 
performed, we conclude that there is a material misstatement of this other information, we 
are required to report that fact.
We have nothing to report in this regard.
Other Companies Act 2006 reporting
Based on the responsibilities described below and our work performed during the course 
of the audit, we are required by the Companies Act 2006 and ISAs (UK) to report on certain 
opinions and matters as described below.
Strategic report and 
Directors’ report 
In our opinion, based on the work undertaken in the course of 
the audit:
•	 the information given in the Strategic report and 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.
In the light of the knowledge and understanding of the 
Group and Parent Company and its environment obtained 
in the course of the audit, we have not identified material 
misstatements in the strategic report or the Directors’ report.
Matters on which we are 
required to report by 
exception
We have nothing to report in respect of the following matters 
in relation to which the Companies Act 2006 requires us to 
report to you if, in our opinion:
•	 adequate accounting records have not been kept by the 
Parent Company, or returns adequate for our audit have 
not been received from branches not visited by us; or
•	 the Parent Company financial statements are not in 
agreement with the accounting records and returns; or
•	 certain disclosures of Directors’ remuneration specified by 
law are not made; or
•	 we have not received all the information and explanations 
we require for our audit.

Responsibilities of Directors
As explained more fully in the Statement of Directors’ responsibilities, the Directors are 
responsible for the preparation of the financial statements and for being satisfied that they 
give a true and fair view, and for such internal control as the Directors determine is necessary 
to enable the preparation of financial statements that are free from material misstatement, 
whether due to fraud or error.
In preparing the financial statements, the Directors are responsible for assessing the Group’s 
and the Parent Company’s ability to continue as a going concern, disclosing, as applicable, 
matters related to going concern and using the going concern basis of accounting unless the 
Directors either intend to liquidate the Group or the Parent Company or to cease operations, 
or have no realistic alternative but to do so.
Auditor’s responsibilities for the audit of the financial statements
Our objectives are to obtain reasonable assurance about whether the financial statements 
as a whole are free from material misstatement, whether due to fraud or error, and to issue an 
auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, 
but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always 
detect a material misstatement when it exists. Misstatements can arise from fraud or error 
and are considered material if, individually or in the aggregate, they could reasonably be 
expected to influence the economic decisions of users taken on the basis of these financial 
statements.
Extent to which the audit was capable of detecting irregularities, including fraud
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:
Non-compliance with laws and regulations
•	 We gained an understanding of the legal and regulatory framework applicable to the 
Group and the components within the group and the industry in which they operate, 
through discussion with management and the Audit Committee and our knowledge of the 
industry; 
•	 We focussed on significant laws and regulations that could give rise to a material 
misstatement in the financial statements, including, but not limited to, the Companies 
Act 2006, UK adopted international accounting standards, the Bribery Act 2010, and tax 
legislation including local taxation and employment law as applicable in component 
jurisdictions in USA, Singapore and China;
•	 We made enquiries of management of whether any correspondence from any relevant 
authorities had been received;
•	 We reviewed the financial statement disclosures and agreed these to supporting 
documentation;
•	 We reperformed tax calculations in respect of corporation tax, employment tax and sales 
tax in each jurisdiction;
•	 We involved tax specialists in the audit of UK corporation tax calculations and disclosures; 
and
•	 We considered compliance with these laws and regulations through discussions with 
management and the Audit Committee. Our procedures also included reviewing minutes 
from board meetings of those charged with governance to identify any instances of 
non‑compliance with laws and regulations.

Auditor’s responsibilities for the audit of the financial statements continued
Fraud
We assessed the susceptibility of the financial statements to material misstatement, including 
fraud. Our risk assessment procedures included:
•	 Assessing the susceptibility of the Group’s financial statements to material misstatement as 
an engagement team, including how fraud might occur throughout the group including 
the parent company and components, by considering industry, legal and external factors 
relevant to the Group; and
•	 Obtaining an understanding of the processes and controls that the group has established 
to address risks identified or that otherwise seek to prevent, deter or detect fraud. 
Based on our risk assessment, we considered the areas most susceptible to fraud in relation 
to the group to be judgements included within the capitalisation of development costs, 
managements impairment reviews of goodwill, management override and revenue 
recognition around the year end.
Our procedures in respect of the above included:
•	 With regard to the fraud risk in management override in controls, our procedures included 
targeting journal transactions with specific criteria, with a focus on large or unusual 
transactions based on our knowledge of the business and agreeing these to supporting 
documentation;
•	 With regard to fraud in revenue recognition, we tested the year end cut off for a 
sample of transactions chosen from the nominal ledger from either side of the year end 
and confirmed the appropriate recognition of the corresponding revenue through to 
supporting documentation;
•	 With regard to the capitalisation of development costs, we reviewed key estimates and 
judgements applied by management to assess their appropriateness (Refer to the key 
audit matters section of our report); and
•	 With regard to the impairment reviews of goodwill we reviewed key estimates and 
judgements applied by management to assess their appropriateness (Refer to the key 
audit matters section of our report).
We also communicated relevant identified laws and regulations and potential fraud risks 
to all engagement team members including component engagement teams who were 
all deemed to have appropriate competence and capabilities and remained alert to any 
indications of fraud or non-compliance with laws and regulations throughout the audit. 
For component engagement teams, we also reviewed the results of their work performed 
in this regard.
Our audit procedures were designed to respond to risks of material misstatement in the 
financial statements, recognising that the risk of not detecting a material misstatement due 
to fraud is higher than the risk of not detecting one resulting from error, as fraud may involve 
deliberate concealment by, for example, forgery, misrepresentations or through collusion. 
There are inherent limitations in the audit procedures performed and the further removed 
non-compliance with laws and regulations is from the events and transactions reflected in the 
financial statements, the less likely we are to become aware of it.
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 Parent Company’s members, as a body, in accordance with 
Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that 
we might state to the Parent Company’s members those matters we are required to state 
to them in an auditor’s report and for no other purpose. To the fullest extent permitted by 
law, we do not accept or assume responsibility to anyone other than the Parent Company 
and the Parent Company’s members as a body, for our audit work, for this report, or for the 
opinions we have formed.

Notes to the financial statements 
for the year ended 31 March 2023
1 Accounting policies
The following accounting policies have been used 
consistently in dealing with items which are considered 
material in relation to the financial statements.
a) Basis of accounting and preparation
The Group and Company financial statements have been 
prepared in accordance with UK adopted International 
Accounting Standards and are in conformity with the 
requirements of the Companies Act 2006. 
The financial statements have been prepared under the 
historical cost convention with the exception of investment 
properties that are carried at valuation. 
The financial statements have been prepared on a 
going concern basis as the Directors have a reasonable 
expectation that the Group and Company have adequate 
resources to continue in operational existence for the 
foreseeable future.
The Group’s presentational currency is Sterling and the 
Company’s functional currency is Sterling and figures are 
rounded to the nearest thousand pounds.
Going concern 
The Group’s business activities, performance, position and 
risks are set out in this Annual Report and Accounts. The 
financial position of the Group, its cash flows, liquidity position, 
borrowing facilities and the use of financial instruments and 
policies relating thereto are detailed in the notes to the 
financial statements. The report also includes details of the 
Group’s risk mitigation and management.
At 31 March 2023, the Group had cash and fixed term 
deposits balances of £22.26m and external debt only in 
relation to its lease liabilities of £1.05m. 
The Directors have reviewed the detailed financial 
projections for the period ending 31 March 2024 including 
sensitivity analysis and reverse stress test, as well as the 
business plan and cash flows for the twelve months from date 
of sign off. In addition, they have considered the principal 
risks faced by the Group, the ongoing potential impact of 
COVID-19, the war in Ukraine and the Group’s significant 
financial headroom and are satisfied that the Group has 
adequate financial resources to continue in operational 
existence for the foreseeable future, a period of at least 
twelve months from the date of approval of this report. 
Accordingly, they continue to adopt the going concern basis 
in preparing the Annual Report and Accounts.
b) Basis of consolidation
These financial statements incorporate the financial 
statements of the Company and its subsidiary undertakings 
using the acquisition method of accounting. The results of 
acquired subsidiary undertakings are included from the 
date of acquisition. No income statement is presented for 
CML Microsystems Plc as provided by Section 408 of the 
Companies Act 2006. 
A subsidiary is defined as a company over which the Group 
has control. The Group controls an entity where the Group 
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. Dormant subsidiaries 
are not included in the consolidated financial statements on 
the basis that they are not material to the Group.
c) Segmental reporting
The Group is focused for management purposes on one 
primary reporting segment, being the semiconductor 
segment, with similar economic characteristics, risks and 
returns, and the Directors therefore consider there to be one 
business segment classification. 
d) Revenue
IFRS 15 establishes principles for determining when and 
how revenue arising from contracts with customers 
should be recognised. The Group recognises revenues 
from semiconductor products at the point of satisfaction 
of its performance obligation and at a determined 
transaction price. 
The Group reviews all income streams against the 
requirements of IFRS 15. An assessment of all contracts and 
revenue streams is undertaken across the Group 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 
obligation in the contract; and
5.	 recognise revenue when (or as) a performance obligation 
is satisfied.
In determining the appropriate method of recognising 
revenue, the Group 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 on 
the basis of contract completion. 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 the consideration 
receivable excluding discounts, rebates, Value Added 
Tax and other sales taxes or duties. The Group has a sales 
and returns agreement with a small number of distributors. 
Estimated returns from distributors are not recognised as 
revenue. Other income such as interest earned and property 
income is recognised as earned.

d) Revenue continued
Revenue relating to semiconductor products
Revenues are recognised when goods have been 
despatched to the customer and it is probable that the 
Group will collect the consideration. Product sales meet 
the definition of a distinct service whereby the associated 
revenue is to be recognised at a point in time, evidenced 
by the despatch of the products to the customer, ie. when 
control passes to the customer. Pricing is fixed and 
determinable pursuant to agreeing upon pricing lists that 
establish stand-alone selling prices. 
Revenue relating to design and development
Revenue is recognised over the period of the contract on the 
basis of percentage contract completion which determines 
the point of satisfaction of its performance obligation and at 
a determined transaction price at a point in time.
e) Intangibles
Goodwill
Goodwill represents the excess of the cost of an acquisition 
over the fair value of the Group’s share of the net identifiable 
assets of the acquired subsidiary at the date of acquisition. 
Goodwill was recognised for the Sicomm acquisition in 
August 2016 and PRFI Limited acquired in March 2020. 
Goodwill is reviewed annually for impairment by comparing 
its carrying value to the value-in-use of the cash generating 
unit; any resultant impairment being charged through the 
Consolidated Income Statement. 
Other intangibles
Externally acquired intangible assets have been recognised 
in accordance with the provisions of IFRS 3 Business 
Combinations in relation to the acquisition of Sicomm and 
PRFI Limited. The other intangibles were deemed to be:
Brands
A brand is defined as a way of how our customers identify our 
business.
Customer relationships
Customer relationships are defined by the methods the 
Company uses to engage with its customers and improve 
the customer experience.
Intellectual property
Intellectual property relates to the intangible assets created 
such as information, ideas, designs and automated 
processes.
These acquired intangibles have been amortised in 
accordance with the following: 
•	 brands – ten years from date of acquisition;
•	 customer relationships – six to nine years from date of 
acquisition; and
•	 intellectual property – ten years from date of acquisition.
The amortised useful life was determined by:
•	 brands – based upon the asset’s relative importance 
to the business and consistent with the range of life 
expectancy identified in the process and previous 
transactions;
•	 customer relationships – based upon the remaining life of 
customer relationships expected to match the product’s life 
cycle which commonly lasts between six to nine years; and
•	 Intellectual property – based upon historical data that 
technology is intended to be used for ten years from 
acquisition. 
Intellectual property and software
The Group is progressively implementing an Enterprise 
Resource Planning system across all companies within the 
Group business functions. The purchased intangible will be 
amortised over its useful economic life of 15 years from its 
date of implementation. 
The Group has also purchased a licence for the use of 
external software for vocoder purposes. This has been 
capitalised as an intangible asset and amortised over ten 
years in line with acquired intellectual property rights above.
Amortisation of all the above intangible assets is recognised 
on consolidation and reported in distribution and 
administration costs in the Consolidated Income Statement. 
f) Research and development
Development expenditures that satisfy the recognition 
criteria as set out in IAS 38 Intangible Assets are shown at 
historical cost less accumulated amortisation since they have 
a finite useful life. In determining the period over which the 
carrying value of the intangible fixed assets are amortised, 
the Group is required to consider the likely period over which 
the developed products are likely to generate economic 
benefits. Amortisation is calculated in line with economic 
benefit commencing when the product is in use. From the 
date amortisation commences, the straight-line method 
is applied to the cost of the development over a period 
of six years, representing the period over which economic 
benefit is derived from developed products, and is charged 
to administration costs in the income statement. Research 
and other development expenditures that fall outside the 
scope of IAS 38 are charged to the income statement when 
incurred. An internally generated intangible asset arising from 
the Group’s business development is recognised only if all of 
the following conditions are met:
•	 an asset is created that can be identified;
•	 it is probable that the asset created will generate future 
economic benefits;
•	 the development cost of an asset can be measured 
reliably;
•	 the product or process is technically and commercially 
feasible; and
•	 sufficient resources are available to complete the 
development and to either sell or use the asset.

g) Property, plant and equipment and investment 
property
All property, plant and equipment, other than investment 
properties, are stated at historical cost. Depreciation is 
provided on all property, plant and equipment other than 
freehold land and investment properties at rates calculated 
to write each asset down to its estimated residual value over 
its expected useful life, as follows:
•	 freehold and long leasehold premises
2% straight line 
•	 short leasehold improvements	

period of the lease 
•	 plant and equipment 
16.67% straight line and 

25% straight line
•	 plant	 	

4% straight line
•	 motor vehicles 	
25% straight line
Investment properties are stated at their fair values and 
are revalued annually by the Directors and every third 
year by an independent chartered surveyor on an open 
market basis. No depreciation is provided on freehold 
investment properties or on leasehold investment properties. 
In accordance with IAS 40 Investment Properties, gains and 
losses arising on revaluation of investment properties are 
shown in the income statement.
h) Taxation
The tax expense represents the sum of the tax currently 
payable, adjustments in respect of prior years and deferred 
tax. The tax currently payable is based on taxable profit for 
the year. Taxable profit differs from net profit as reported in 
the income statement because it excludes items of income 
or expense that are taxable or deductible in other years and 
it further excludes items that are never taxable or deductible. 
The Group’s liability for current tax is calculated by using tax 
rates that have been enacted or substantively enacted by 
the year end.
Deferred tax is the tax expected to be payable or 
recoverable on differences between the carrying amount 
of assets and liabilities in the financial statements and 
the corresponding tax bases used in the computation of 
taxable profit and is accounted for using the balance sheet 
liability method. Deferred tax liabilities are 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 tax profit nor 
the accounting profit. Deferred tax liabilities are recognised 
for taxable temporary differences arising on investments in 
subsidiaries except where the Group is able to control the 
reversal of the temporary differences and it is probable that 
the temporary difference will not reverse in the foreseeable 
future. Deferred tax is calculated at the tax rates that are 
expected to apply to the period when the asset is realised, 
or the liability is settled, based upon tax rates that have been 
enacted or substantively enacted by the year end. Deferred 
tax is charged or credited in the income statement, except 
when it relates to items credited or charged directly to equity, 
in which case the deferred tax is also dealt with in equity.
i) Inventories
Inventories are valued on a first‑in, first‑out basis and 
are stated at the lower of cost and net realisable value. 
In respect of work in progress and finished goods, cost 
comprises direct materials, direct labour and a proportion of 
overhead expenses appropriate to the business. 
j) Foreign currencies
Assets and liabilities denominated in foreign currencies are 
translated at the rates of exchange ruling at the year end. 
Transactions in foreign currencies are recorded at the rates 
ruling at the date of the transactions. All differences are 
recognised in the income statement. The financial statements 
of the overseas subsidiaries are translated into Sterling 
at the average rate of exchange for the period for the 
income statement and at the closing rate for the statement 
of financial position. Translation differences are dealt with 
through the foreign exchange reserve in shareholders’ equity. 
The Group decided to deem the cumulative amount of 
exchange differences arising on consolidation of the net 
investments in subsidiaries at 1 April 2004 to be zero.
k) Investments in subsidiary undertakings
Investments are stated at cost less any provision for 
diminution in value. Investments in subsidiary undertakings are 
reviewed for impairment on an annual basis.
l) Cash and cash equivalents
Cash and cash equivalents include cash in hand, deposits 
held at call with banks, other short‑term highly liquid 
investments with original maturities of three months or less and 
bank overdrafts where there is a set‑off arrangement with the 
bank. Other bank overdrafts are shown within borrowings in 
current liabilities on the statement of financial position.

m) Employee benefits – pension obligations
Group companies operate both defined benefit and defined 
contribution pension schemes. The schemes are funded 
through payments to funds administered separately by 
trustees and these are determined by periodic actuarial 
calculations in respect of the defined benefit pension 
schemes. The liability recognised in the statement of financial 
position in respect of the defined benefit pension schemes 
is the present value of the defined benefit obligation at 
the year end less the fair value of the scheme assets. 
Independent actuaries using the projected unit method 
calculate the defined benefit obligation annually. 
The current service cost, which is the increase in the present 
value of the retirement benefit obligation resulting from 
employee service in the current year, and gains and losses on 
settlements and curtailments, which arise on transactions that 
eliminate part or all of the benefits provided or when there 
are amendments to terms such that a significant element of 
future service will no longer qualify for benefits or will qualify 
only for reduced benefits, are included within operating profit 
in the Consolidated Income Statement. Past service credits/
costs are those service credits/costs in relation to prior years’ 
service costs as a result of changes of future benefits earned 
by members. Past service credits/costs are recognised 
immediately in the Consolidated Income Statement.
Re-measurement of the UK defined benefit scheme due 
to actuarial gains and losses from experience adjustments 
and changes in actuarial assumptions is immediately 
recognised in other comprehensive income and charged or 
credited directly to equity. For defined contribution schemes, 
contributions are recognised as an employee benefit 
expense in the Consolidated Income Statement when they 
are due.
n) Employee benefits – share‑based payments
Share options which are equity settled are valued using the 
Black‑Scholes model. The fair value at the date of the grant 
is charged to the income statement over the vesting period 
of the share‑based payment scheme. The value of the 
charge is adjusted to reflect expected and actual levels of 
options vesting.
Cancelled or settled options are accounted for as an 
acceleration of vesting. The unrecognised grant date fair 
value is recognised in the profit or loss in the year that the 
options are cancelled or settled.
o) Government grants
Government grants receivable to assist the Group with 
costs in respect of development work are credited against 
capitalised development costs or capitalised property, plant 
and equipment so as to match them with the expenditure 
to which they relate. Other grants that are not of a capital 
nature are credited to the income statement as part of 
other operating income. Grants are only recognised when 
all conditions of the grant have been complied with and are 
matched to the expenditure to which they relate.
p) Leases
Group as a lessee
Right-of-use assets
A right-of-use asset is recognised at commencement of 
the lease and initially measured at the amount of the lease 
liability, plus any incremental costs of obtaining the lease and 
any lease payments made at or before the leased asset is 
available for use by the Group.
The right-of-use asset is subsequently measured at cost 
less accumulated depreciation and any accumulated 
impairment losses. The depreciation methods applied 
are as follows:
•	 leased property 
over the term of the lease
•	 leased vehicles 
over the term of the lease
Lease liabilities
On commencement of a contract (or part of a contract) 
which gives the Group the right to use an asset for a period of 
time in exchange for consideration, the Group recognises a 
right-of-use asset and a lease liability unless the lease qualifies 
as a “short-term” lease or a “low-value” lease.
Initial measurement of the lease liability
The lease liability is initially measured at the present value 
of the lease payments during the lease term discounted 
using the interest rate implicit in the lease, or the incremental 
borrowing rate if the interest rate implicit in the lease cannot 
be readily determined. 
The lease term is the non-cancellable period of the lease 
plus extension periods that the Group is reasonably certain to 
exercise and termination periods that the Group is reasonably 
certain not to exercise.
Lease payments include fixed payments, less any lease 
incentives receivable, variable lease payments dependent 
on an index or a rate (such as those linked to LIBOR and any 
future agreements linked to SONIA) and any residual value 
guarantees. Variable lease payments are initially measured 
using the index or rate when the leased asset is available 
for use.
Subsequent measurement of the lease liability
The lease liability is subsequently increased for a constant 
periodic rate of interest on the remaining balance of the 
lease liability and reduced for lease payments.
Interest on the lease liability is recognised in profit or loss. 
Variable lease payments not included in the 
measurement of the lease liability as they are not 
dependent on an index or rate, are recognised in profit 
or loss in the period in which the event or condition that 
triggers those payments occurs.

p) Leases continued
Group as a lessor
Leases of property, plant and equipment where the 
Group has substantially all the risk and rewards of 
ownership are classified as operating leases. Rental 
income under these leases is credited to the income 
statement on a straight‑line basis and any contingent 
rents are recognised as income in the period to which 
they relate.
q) Dividends
Dividend distributions to the Company’s shareholders 
are recognised as a liability in the Group’s financial 
statements in the period in which the dividends are 
approved by the Company’s shareholders.
r) Critical accounting judgements and key sources 
of estimation uncertainty
The preparation of consolidated financial statements 
under IFRS requires the Group to make estimates and 
assumptions that affect the application of policies 
and reported amounts. Estimates and judgements 
are continually evaluated and are based on historical 
experience and other factors, including expectations 
of future events that are believed to be reasonable 
under the circumstances. The resulting accounting 
estimates and assumptions will, by definition, seldom 
equal the related actual result. The amortisation period 
of development costs, the assumptions made (for 
example mortality, inflation and discount rates) for the 
UK defined benefit pension scheme and the impairment 
of goodwill are considered to be critical accounting 
estimates and judgements; details of which are referred 
to in this accounting policies note, sections e, f, h, m and 
t. Deferred tax assets are only recognised when there is a 
reasonable expectation of recovery.
Critical accounting judgements
The following are the critical judgements, apart from 
those involving estimations (which are dealt with 
separately below), that the Directors have made in the 
process of applying the Group’s accounting policies and 
that have the most significant effect on the amounts 
recognised in the financial statements.
•	 Research and development  
– capitalisation of development costs 
Distinguishing whether development expenditure satisfies 
the recognition requirements for the capitalisation of 
development costs requires the exercise of judgement.
	
In satisfying the recognition requirements for development 
costs a number of judgement factors include future 
demand and the resource necessary to finalise the 
development roadmap over the next few years. This 
is necessary as the economic success of any product 
development is uncertain and may be subject to 
future technical problems at the time of recognition. 
Judgements are based on the information available at 
each balance sheet date. All internal activities relating to 
research and development are continuously monitored by 
the Group. 
•	 Research and development  
– amortisation and impairment 
The Group exercises judgement concerning the 
future in assessing the carrying amounts of capitalised 
development costs. The criteria IAS 38 has been applied 
in considering the future economic benefit as a result of 
investment.
	
The annual impairment review resulted in the carrying 
costs of the development expenditure needing an 
impairment of £Nil for the year (2022: £123,000). The 
impairment is based upon an updated judgement that 
a product previously deemed viable is now unlikely 
to be released. The product remains as part of the 
Group’s development, with final viability of the product 
expected to be confirmed within the next twelve months. 
Should the outcome be successful and the updated 
assessment be that the product is viable, the impairment 
would be reversed.

r) Critical accounting judgements and key sources 
of estimation uncertainty continued 
Key sources of estimation uncertainty
•	 Impairment of goodwill  
An annual review is carried out (as set out in note 13) 
as to whether the current carrying value of goodwill is 
impaired. Detailed calculations are performed based on 
(i) discounting expected pre-tax cash flows of the relevant 
cash generating units and discounting these at an 
appropriate discount rate; and/or (ii) the comparison of 
carrying value to the fair value less cost of disposal of the 
cash generating unit; the determination of these factors 
requires the exercise of judgement.
•	 UK defined benefit pension scheme 
Actuarial assumptions are made in valuing future benefit 
pension obligations (as set out in note 26). The principal 
significant assumptions relate to the rate of inflation, the 
discount rate and life expectancy of members. Estimates 
are used for these factors in determining the pension costs 
and liabilities in the financial statements.
•	 Overhead absorption 
Estimates are made of the level of overhead absorbed 
against inventory at the year-end date. The Group has an 
overhead absorption rate which is applied consistently 
throughout the year; due to the nature of trends and 
customer requirements there is an estimate in determining 
the cost in the financial statements.
•	 Recognition of deferred tax assets 
The extent to which deferred tax assets can be recognised 
is based on an assessment of probabilities that future 
taxable incomes in jurisdictions will be available against 
which the deductible temporary differences and tax loss 
carry-forwards can be utilised in the future.
s) Financial instruments
(i) Recognition of financial instruments
Financial assets and financial liabilities are recognised when 
the Company becomes party to the contractual provisions of 
the instrument.
(ii) Financial assets
Initial and subsequent measurement of financial assets
(a) Trade, Group and other receivables 
Trade receivables are initially measured at their transaction 
price. Group and other receivables are initially measured 
at fair value plus transaction costs. Receivables are held to 
collect the contractual cash flows which are solely payments 
of principal and interest. 
Receivables are subsequently measured at amortised 
cost using the effective interest rate method. Receivables 
are reviewed annually for impairment and an impairment 
charge recognised where identified. Historic, current, and 
forward‑looking information is considered annually in our 
review of the requirement to include an estimated credit 
loss provision.
(iii) Financial liabilities and equity
Financial liabilities and equity instruments are classified 
according to the substance of the contractual arrangements 
entered into. An equity instrument is any contract that 
evidences a residual interest in the assets of the Company 
after deducting all of its liabilities.
Initial and subsequent measurement of financial liabilities
(a) Trade, Group, lease liabilities and other payables 
Trade, Group, lease liabilities and other payables are initially 
measured at fair value, net of direct transaction costs, and 
subsequently measured at amortised cost.
(b) Bank overdrafts and loans 
Bank overdrafts are initially measured at fair value, and are 
subsequently measured at amortised cost. Finance charges, 
including premiums payable on settlement or redemption, 
are recognised in profit or loss over the term of the loan using 
an effective rate of interest.
(c) Equity instruments 
Equity instruments issued by the Company are recorded at 
fair value on initial recognition net of transaction costs. 
(iv) Derecognition of financial assets (including write‑offs) 
and financial liabilities
A financial asset (or part thereof) is derecognised when 
the contractual rights to cash flows expire or are settled, or 
when the contractual rights to receive the cash flows of the 
financial asset and substantially all the risks and rewards of 
ownership are transferred to another party. When there is no 
reasonable expectation of recovering a financial asset it is 
derecognised. The gain or loss on derecognition of financial 
assets measured at amortised cost is recognised in profit 
or loss.
A financial liability (or part thereof) is derecognised when the 
obligation specified in the contract is discharged, cancelled 
or expires. Any difference between the carrying amount of 
a financial liability (or part thereof) that is derecognised and 
the consideration paid is recognised in profit or loss.

t) Impairment of property, plant and equipment 
(including right-of-use assets), development costs and 
intangible assets other than goodwill
At each year end, the Group reviews the carrying amounts 
of its non-current assets with finite useful lives to determine 
whether there is any indication that those assets have 
suffered an impairment loss. If such indications exist, the 
recoverable amount of the asset is estimated in order to 
determine the extent of any impairment loss. Where the asset 
does not generate cash flows that are independent from 
other assets, the Group estimates the recoverable amount 
of the cash generating unit to which the asset belongs. 
An intangible asset with an indefinite useful life is tested for 
impairment annually and whenever there is an indication 
that an asset may be impaired. The recoverable amount is 
the higher of fair value less costs to sell and value‑in-use. 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 risks specific to the asset. 
If the recoverable amount of an asset (or cash generating 
unit) is estimated to be less than its carrying amount, the 
carrying amount of the asset (or cash generating unit) is 
reduced to its recoverable amount. An impairment loss is 
recognised as an expense immediately, unless the relevant 
asset is carried at a revalued amount, in which case the 
impairment loss is treated as a revaluation decrease until the 
associated revaluation reserve is extinguished.
u) Provisions
Provisions are recognised when the Group has a present 
obligation as a result of a past event which it is probable 
will result in an outflow of economic benefits that can 
be reliably estimated. Provisions are discounted where 
material to do so. 
v) Share capital
Ordinary shares are classified as equity. Incremental costs 
directly attributable to the issue of new shares or options 
are shown in equity as a deduction, net of tax, from the 
proceeds. 
Where the Company has purchased its own equity share 
capital, the consideration paid, including directly attributable 
incremental costs, is deducted from retained earnings until 
the shares are cancelled. On cancellation, the nominal value 
of the shares is deducted from share capital and the amount 
is transferred to the capital redemption reserve. 
w) Acquisitions
The acquisition of subsidiaries is accounted for using the 
acquisition method. The cost of acquisition is measured at 
the aggregate of the fair values, at the date of change of 
control, of assets given, liabilities incurred or assumed, and 
equity instruments issued by the Group in exchange for 
control of the acquiree, plus any costs relating to the issue 
of debt or equity securities. Any costs directly attributable to 
the business combination are expensed to the Consolidated 
Income Statement. The acquiree’s identifiable assets, 
liabilities and contingent liabilities are recognised at their fair 
value at the acquisition date. 
Goodwill arising on acquisition is recognised as an asset and 
initially measured at cost, being the excess of the cost of the 
business combination over the Group’s interest in the net 
fair value of the identifiable assets, liabilities and contingent 
liabilities recognised. If, after reassessment, the Group’s 
interest in the net fair value of the acquiree’s identifiable 
assets, liabilities and contingent liabilities exceeds the cost 
of the business combination, the excess is recognised 
immediately in profit or loss. 
x) Discontinued operations
A discontinued operation is a component of the 
consolidated entity that has been disposed of or is classified 
as held for sale and that represents a separate major line 
of business or geographical area of operations, is part of a 
single co-ordinated plan to dispose of such a line of business 
or area of operations, or is a subsidiary acquired exclusively 
with a view to resale. The results of discontinued operations 
are presented separately in the Consolidated Income 
Statement. 
y) Adoption of International Accounting Standards
New standards, amendments and interpretations 
The Group has applied all IFRSs that are effective for the 
years ended 31 March 2023 and 31 March 2022. Adoption of 
new standards had no impact on the financial statements.
New standards, amendments and interpretations not 
yet adopted
At the date of authorisation of these financial statements, 
the following standards and interpretations that are relevant 
to the Group, which have not been applied in these financial 
statements, were in issue but not yet effective.

2 Segmental analysis
Reported segments and their results, in accordance with IFRS 8, are based on internal management reporting information that is regularly reviewed by the Chief Operating Decision Maker 
(Chris Gurry). The measurement policies the Group uses for segmental reporting under IFRS 8 are the same as those used in its financial statements.
The Group is focused for management purposes on one operating segment, which is reported as the semiconductor segment, with similar economic characteristics, risks and returns, and the 
Directors therefore consider there to be one single segment, being semiconductor components for the communications industry.

In accordance with IFRS 15, within the Group’s one operating segment there is revenue of £20,643,000 (2022: £16,964,000) made up of revenue from semiconductor products of £19,551,000 
(2022: £15,909,000) and revenue from design and development services of £1,092,000 (2022: £1,055,000), as detailed in the Group’s revenue recognition policy (see note 1d).
The Group does not have any contract assets as at 31 March 2023 (2022: £Nil at 31 March) from semiconductors as it does not fulfil any of its performance obligations in advance of 
invoicing to its customer. The Group has contract assets of £363,000 as at 31 March 2023 (2022: £157,000 at 31 March) from design and development. The Group, however, does have 
contractual balances in the form of trade receivables. See note 20 for disclosure of this. The Group does not have any contractual liabilities as at 31 March 2023 (£Nil at 31 March 2022) 
from semiconductors as all performance obligations are performed in advance. The Group has contract liabilities of £17,000 as at 31 March 2023 (2022: £Nil at 31 March) from design and 
development.
The Group expects that all contractual costs capitalised or any outstanding performance obligations will be completed within the next twelve months.

A deferred tax charge of £348,000 was recognised on an actuarial gain of £1,393,000 on a 
retirement benefit net obligation being recognised in the year in the Consolidated Statement 
of Total Comprehensive Income (2022: deferred tax charge of £827,000 on an actuarial 
gain of £3,307,000 on a retirement benefit net obligation and a deferred tax charge on 
remeasurement of deferred tax balances of £345,000 led to a net deferred tax charge of 
£482,000). Deferred tax assets have only been recognised on partial losses to the extent that 
these losses utilised are deemed recoverable.
The Finance Bill 2021 provides that the main rate of corporation tax be increased from 19% 
to 25% with effect from 1 April 2023. The Directors therefore consider it appropriate to use 25% 
as the rate deferred tax should be provided for. Further details of the effects can be found in 
note 25.

The goodwill relates to (i) Sicomm group of companies £5,898,000 which is held in RMB, upon 
Group consolidation is therefore subject to foreign exchange between periods; and (ii) PRFI 
£1,531,000.
Annual impairment testing
Goodwill is not amortised under IFRS but instead tested annually for impairment. An 
annual impairment review is carried out in accordance with the accounting policies set out in 
note 1, namely: the Group reviews the carrying amounts of its goodwill to determine whether 
there is any indication that those assets have suffered an impairment loss. The recoverable 
amount of the asset is estimated in order to determine the extent of any impairment loss. 
Where the asset does not generate cash flows that are independent from other assets, the 
Group estimates the recoverable amount of the cash generating unit to which the asset 
belongs. The recoverable amount is the higher of fair value less costs to sell and value-in-use. 
Goodwill and other intangibles are allocated to cash generating units, which represent the 
appropriate level that those cash generating units are monitored for internal management 
purposes. In assessing value-in-use, the estimated future cash flows are discounted to their 
present value utilising a pre‑tax discount rate that reflects current market assessments of the 
time value of money and risks specific to the asset, in addition to the basis of the weighted 
average cost of capital for the Group. 
Projections are based on budgets for year one and cash flow projections for the following 
four years’ extrapolations using growth rates and terminal cash flows considered to be in line 
with the economic environment in which the cash generating unit operates, past and current 
local management experience. In accordance with IAS 36 Impairment of Assets, growth 
rates do not exceed the long‑term average growth rates for the industry in that jurisdiction. 
If the recoverable amount of the cash generating unit is estimated to be less than its carrying 
amount, the carrying amount of the cash generating unit is reduced to its recoverable 
amount. An impairment loss is recognised as an expense immediately, unless the relevant 
asset is carried at a revalued amount, in which case the impairment loss is treated as a 
revaluation decrease until the associated revaluation reserve is extinguished.
Evaluation of Sicomm goodwill and PRFI goodwill 
The recoverable amount of Sicomm and PRFI related goodwill is determined using the 
value‑in-use methodologies. For Sicomm related goodwill, the pre-tax discount rate used 
was 18.44% and growth rates vary from 5% to 7.5% over a five‑year prospective period and 
long‑term growth rate is 5% (2022: pre-tax discount rate used was 13.11% and growth rates 
vary from 7.5% to 10%) and for PRFI related goodwill, the pre-tax discount rate used was 
18.21% and growth rates of 4% per year for a five‑year prospective period and long term 
growth rate is 4% (2022: pre-tax discount rate used was 12.99% and growth rates of 3%). 
Management consider these key assumptions do not differ from past experience or external 
sources of information.

Sensitivity analysis
For the value-in-use methodology in respect of the Sicomm impairment review, the key assumptions are growth rates and discount rate. Long‑term growth rates would have to average 2.8% 
(2022: 7.3%) or pre‑tax discount rates move to 22% (2022: 13.67%) for carrying value to be impacted by any impairment. Sensitivity analysis of these key assumptions is built into our annual 
impairment testing modelling and a decrease in the long-term growth rate of 1.5% (2022: 0.7%) would lead to an impairment. In respect of the PRFI impairment review, the key assumptions 
are growth rates and discount rate. Growth rates in years 2-5 and the long-term growth rate would have to be less than 2.2% (2022: 1.0%) or pre-tax discount rates move to 19.28% (2022: 
17.19%) or carrying value to be impacted by any impairment. Sensitivity analysis of these key assumptions is built into our annual impairment testing modelling.

No government grants have been credited to the cost of development in arriving at the net 
book value at the year end (2022: £Nil).
The annual impairment review resulted in the carrying costs of the development expenditure 
needing an impairment of £Nil for the year (2022: £123,000). Impairment losses are included in 
the distribution and administration costs in the Group’s income statement.

Investment properties were measured at current market valuation. No depreciation is 
provided on freehold investment properties or on long leasehold investment properties. 
In accordance with IAS 40, gains and losses arising on revaluation of investment properties 
are shown in the income statement. The open market valuation of investment properties 
recognised is £Nil (2022: £Nil). Investment properties held for sale is £1,975,000 (2022: 
£1,975,000). 
The value of the investment properties were they to be held at historic cost would be 
£1,492,000 (2022: £1,492,000). 
The Group/Company does not incur significant costs not otherwise recharged to its tenants 
for its investment properties.
Valuations were based on what is determined to be the highest and best use. When 
considering the highest and best use the Directors considered, on a property-by-property 
basis, its actual and potential uses which are physically, legally and financially viable. Where 
the highest and best use differed from the existing use, the valuer considered the cost and 
likelihood of achieving and implementing this change in arriving at its valuation.
The methods of fair value measurement are classified into a hierarchy based on the reliability 
of the information used to determine the valuation, as follows:
•	 level 1: valuation based on inputs on quoted market prices in active markets;
•	 level 2: valuation based on inputs other than quoted prices included within level 1 that 
maximise the use of observable data directly or from market prices or indirectly derived 
from market prices; and
•	 level 3: where one or more inputs to valuations are not based on observable market data. 
The investment property was reclassified on 31 March 2022 as held for sale as the property 
became vacant with no prospective tenant in place and is held based upon the current 
market valuation methodology. The property is currently expected to sell within the next 
twelve months.

Disclosure of foreign currency risk is provided in note 22. Cash, cash equivalent and fixed term deposits as per the Statement of Cash Flows includes cash on deposit and cash at bank 
totalling for the Group £21,041,000 (2022: £19,084,000) and the Company £17,762,000 (2022: £15,744,000). There is an unlimited cross guarantee between the parent company and the two

22 Financial instruments
Financial instruments
The Group’s financial instruments can comprise cash balances, overdraft facilities and items such as trade receivables and trade payables and leased liabilities that arise directly from its 
operations. The overall objective of the Board is to reduce risks where possible within a competitive, dynamic and flexible trading environment. 
Capital market risk is discussed below. The risks arising from the Group’s financial instruments are interest rate risk, liquidity risk and foreign currency risk. The policies for managing these risks 
are summarised below and have been applied throughout the year. 
Credit and cash flow risk
The Group has little exposure to credit and cash flow risk. It is, and has been throughout the year under review, the Group’s policy that no trading in financial instruments shall be undertaken. 
The maximum credit exposure of financial instruments within the scope of IFRS 9 Financial Instruments, without taking account of collateral, is represented by the carrying amount for trade 
receivables, other receivables and cash and cash equivalents included in the Statement of Financial Position. Credit risk on cash and cash equivalents is managed by depositing funds with 
high rated banks.
Capital market risk
The Board considers capital to be the carrying amount of equity and debt. The Group presently does not have any external debt with the exception to right-of-use assets. Its overall capital 
objective is, in the light of changes in economic conditions, to maintain a strong and efficient capital base to support the Group’s strategic growth objectives, provide progressive returns to 
shareholders and safeguard the Group’s status as a going concern. 
Interest rate and liquidity risk
Cash balances are placed so as to maximise interest earned while maintaining the liquidity requirements of the business. 
The Directors regularly review the placing of cash balances. A significant movement in LIBOR or the transition to SONIA would be required to have a material impact on the cash flow of the 
Group. The gross overdraft facility provided by the Group’s principal bankers is £500,000 (2022: £400,000), and US$100,000 (2022: US$100,000), and is subject to renewal annually.

Foreign currency risk
The Group has overseas subsidiary operations in the US, China and Singapore. As a result, the Group’s Sterling Statement of Financial Position could be affected by movements in the US 
Dollar, Chinese Renminbi and Singapore Dollar to Sterling exchange rates. At 31 March 2023, the Group had cash and cash equivalents denominated in foreign currencies of approximately 
£5.3m (2022: £3.6m), of which approximately 81% (2022: 52%) was denominated in US Dollars, 19% in Chinese Renminbi (2022: 47%) and 1% (2022: 1%) in Singapore Dollars. As national currency 
of China, the Chinese Renminbi is subject to foreign exchange controls made by that country. The effects of foreign exchange recognised in the income statement amounted to a loss of 
£(10,000) (2022: gain of £44,000).

Trade and other receivables are all due within six months.
At 31 March 2023, £727,000 (2022: £483,000) of trade receivables were denominated in Sterling, £680,000 (2022: £470,000) in US Dollars, and £Nil in Chinese Renminbi (2022: £16,000). 
The Directors consider that the carrying amount of trade and other receivables approximate to their fair value. Cash, cash equivalents and deposits of £22,259,000 (2022: £25,042,000) 
comprise cash and short‑term deposits held by the Group treasury function. The carrying amount of these assets approximates to their fair values. 
Impairment of financial assets
The Group and Company’s credit risk management practices and how they relate to the recognition and measurement of expected credit losses is set out below.
Definition of default
The loss allowance on all financial assets is measured by considering the probability of default.
Receivables are considered to be in default when the principal or any interest is significantly more than the associated credit terms past due, based on an assessment of past payment 
practices and the likelihood of such overdue amounts being recovered.

Determination of credit-impaired financial assets
The Group and Company considers financial assets to be “credit-impaired” when the following events, or combinations of several events, have occurred before the year end:
•	 significant financial difficulty of the counterparty arising from significant downturns in operating results and/or significant unavoidable cash requirements when the counterparty has 
insufficient finance from internal working capital resources, external funding and/or Group support;
•	 a breach of contract, including receipts being more than materially past due; or
•	 it becoming probable that the counterparty will enter bankruptcy or liquidation.
Write-off policy
Receivables are written off by the Group when there is no reasonable expectation of recovery, such as when the counterparty is known to be going bankrupt, or into liquidation or 
administration. Receivables will also be written off when the amount is more than materially past due.
Impairment of trade receivables
The Group and Company calculates lifetime expected credit losses for trade receivables using a portfolio approach. Receivables are grouped based on the credit terms offered and the 
type of product sold. The probability of default is determined at the year end based on the ageing of the receivables and historical data about default rates on the same basis. That data is 
adjusted if the Group and Company determines that historical data is not reflective of expected future conditions due to changes in the nature of its customers and how they are affected by 
external factors such as economic and market conditions.
The average credit period was 25 days (2022: 22 days). There were no impairment losses recognised on any financial assets measured at amortised cost at 31 March 2023 (2022: £Nil). 
Based on the profile of the Group and Company’s trade receivables, history of bad debts and looking forward to future events which may affect recoverability of receivables, no loss 
allowance provision has been recognised. At 31 March 2023, of the £1,405,000 (2022: £969,000) trade receivables outstanding, they were all within 0‑60 days (2022: all within 0-60 days).

At 31 March 2023, the total financial liabilities consisted of £1,584,000 (2022: £1,865,000) denominated in Sterling, £1,114,000 (2022: £545,000) in US Dollars, and £294,000 in Chinese Renminbi 
(2022: £314,000). 
The maturity of the gross contractual undiscounted cash flows due on the Group’s and Company’s financial liabilities with the exception of lease liabilities are all less than six months. 
Group financial liabilities totalling £1,841,000 (2022: £2,256,000) and Company financial liabilities totalling £486,000 (2022: £487,000) equal the gross contractual cash flows. The gross 
contractual cash flows relating to lease liabilities for the Group total £1,166,000 (2022: £540,000) with £248,000 (2022: £216,000) within twelve months and £918,000 (2022: £279,000) greater than 
twelve months.
Sensitivity analysis
Foreign currency sensitivity
The following table details the Group’s sensitivity to a 10% change in exchange rates against the Sterling equivalents. The sensitivity analysis of the Group’s exposure to foreign exchange risk 
at the reporting date has been determined based on the change taking place at the beginning of the financial year and held constant throughout the reporting period. There is no foreign 
exchange risk in relation to the Company.

The Group and Company closely monitors its access to bank and other credit facilities in comparison to its outstanding commitments on a regular basis to ensure that it has sufficient funds to 
meet the obligations of the Group as they fall due.
The Board receives regular forecasts that estimate the cash flows over the next twelve months, so that management can ensure that sufficient financing is in place as it is required. 
Detailed analysis of the debt facilities held and available to the Group are disclosed in this note above.

25 Deferred tax continued
The financial statements include a deferred tax asset of £766,000 (2022: £1,550,000) of which £162,000 (2022: £798,000) arises as a result of trading losses. In accordance with the requirement 
of IAS 12 Income Taxes, the Directors have considered the likely recovery of this deferred tax asset. The Directors have taken into account expected future taxable profits and expect an 
improvement in profitability and profits in future periods and that this will be sustained. Accordingly, the Directors have satisfied themselves that it is appropriate to recognise the above 
deferred tax asset. The deferred gain of £348,000 (2022: deferred gain of £827,000) relates to the retirement benefit obligation (see note 26). The Directors consider the deferred tax asset 
relating to the retirement benefit obligation to be recoverable on the basis that the deficit is a long‑term liability that will be satisfied from future profitability.
The Finance Bill 2021 provides that the main rate of corporation tax be increased from 19% to 25% with effect from 1 April 2023. The Directors therefore consider it appropriate to use 25% as the 
rate deferred tax should be provided for.
In accordance with the requirement of IAS 12 Income Taxes, the Directors have considered the likely recovery of any deferred tax asset as part of this process. 
26 Retirement benefit obligations
Explanation of current pension schemes in operation worldwide – defined contribution schemes
The Group operates several pension schemes, mostly of a defined contribution nature, around the world. Today, the majority of the Group’s employees are members of defined contribution 
schemes. All schemes are operated by trustees, independent of operation by the Group and Company. The Trustees are responsible for the operation and governance of the schemes. 
Defined contribution pension schemes pay fixed contributions from Group companies (where applicable) to employees’ individual investment funds. There is therefore no further liability on the 
Group balance sheet relating to defined contribution pension schemes. For the defined contribution schemes operated throughout the Group the employer contributions are generally up to 
6% (2022: 6%) of eligible salary but are subject to minimum employee contributions. 
Explanation of UK defined benefit pension scheme (closed to new members on 1 April 2002)
Following the triennial valuation of the defined benefit scheme as at 31 March 2020, the Group considers that the contribution rates set at the last valuation date are sufficient to eliminate 
the deficit over the agreed period and that regular contributions, which are based on service costs, will not increase significantly. The defined benefit scheme returned to surplus as at 
31 December 2020.

26 Retirement benefit obligations continued
Details from this point to the end of this note relate to the UK defined benefit scheme only.
This part of the note therefore details the financial and demographic assumptions made in 
estimating the defined benefit obligation, together with an analysis of the components of the 
pension liability. The Consolidated Financial Position therefore includes a retirement benefit 
liability which is the expected future cash flows to be paid out by the UK defined benefit 
scheme, offset by assets held by that scheme to meet those liabilities. 
Historically, the majority of the Group’s employees in the UK were members of a defined 
benefit scheme (which is governed by the UK Pensions Regulator) that was closed to new 
members on 1 April 2002 and with effect from 31 March 2009 future pension accrual ceased 
for the remaining active members. Under the UK defined benefit pension scheme’s trust deed 
the Company has the authority to appoint up to two‑thirds of the Trustees. Currently there are 
one member‑appointed Trustee and two Company‑appointed Trustees. The Trustees of this 
defined benefit pension scheme are also responsible for the scheme’s investment strategy, 
as well as the operation and governance of that scheme.
The total contributions to the schemes over the year were:

In relation to the UK defined contribution scheme, the Group had outstanding contributions

administrative expenses are discussed further below in this note. 
Triennial actuarial funding valuation and IAS 19 Employee Benefits accounting valuation
The pension scheme is subject to a full actuarial valuation every three years using assumptions 
agreed between the Trustees and the Company. The latest available triennial actuarial 
funding valuation of the defined benefit scheme in the UK was prepared as at 31 March 2020. 
The purpose of this valuation is to design a funding plan to ensure that the pension scheme 
has sufficient funds available to meet future defined benefit payments. This most recent 
triennial actuarial valuation carried out by an independent professionally qualified actuary, 
as at 31 March 2020, resulted in a net pension (deficit) of £2,242,000 (1 April 2017: net pension 
surplus of £1,890,000). The market value of the assets of the scheme as at 31 March 2020 
was £19,144,000 (1 April 2017: £19,490,000) and the actuarial valuation showed that these 
assets had insufficient coverage at 90% (1 April 2017: 111%) of the benefits which accrued to 
members, after allowing for expected future increases in these benefits. 
The main actuarial assumptions used were allowance for future investment returns; ie. the 
discount rate, of 3.65% p.a. both before and after retirement; pensions accrued prior to 
6 April 1997 and after April 2005 will increase in payment at 3% p.a. compound; pensions 
accrued between 6 April 1997 and 6 April 2005 will increase in payment at 5% p.a.; ie. in line 
with RPI subject to a minimum 3% p.a.; pensions accrued between 6 April 2005 and 31 March 
2009 will increase in payment at 3% p.a. compound and early leaver revaluations will be at 
2.85% p.a.
The valuation calculated under the funding valuation basis of £2,242,000 pension deficit 
above is different to the accounting valuation presented in the Group Consolidated Financial 
Position, which shows a net pension liability of £1,204,000. Differences arise between the 
funding valuation and accounting valuation, mainly due to the use of different assumptions 
in valuing the liabilities in accordance with the accounting standard IAS 19 Retirement 
Benefits, together with any changes in market conditions between the two valuation dates 
of 31 March 2020 and 31 March 2023. Therefore, for funding valuation purposes the liabilities 
are determined based on assumptions set by the Trustees following consultation with the 
Company and the scheme actuaries. For example, the discount rate used for the most recent 
funding valuation is based on a 3.65% discount rate, whereas in the financial statements the 
liabilities are determined in accordance with IAS 19 and this accounting valuation uses a 
discount rate predicated on high quality (AA) corporate bond yields of an appropriate term 
equating to 4.8%. 
Funding of the defined benefit scheme is agreed with the Trustees following each triennial 
actuarial valuation and the following funding agreement has been put in place from 
1 April 2021 until the earlier of any revised settlement arising from the next triennial valuation 
or by 31 March 2024 (“future revised date”); all administration expenses of running the 
scheme are met directly by the scheme and all PPF levies (and any minor scheme expenses 
eg. Pensions Regulator levies) will be paid from the scheme and will not be reimbursed by 
the employer. The employer made a one-off advance contribution of £225,000 towards the 
running expenses in the year to 31 March 2022. The next triennial actuarial funding valuation 
will be as at 31 March 2023.
The net pension liability recognised in these consolidated financial statements has been 
calculated reflecting the most recent accounting valuation under IAS 19 to reflect the assets 
and liabilities of the scheme as at 31 March 2023, using assumptions further in this note. 
As at the last valuation date, the present value of the defined benefit obligation included 
approximately £9,364,000 (2022: £13,891,000) relating to deferred members and £7,565,000 
(2022: £9,620,000) relating to pension members.

Risk management
The cost of the UK defined benefit pension scheme depends on a number of assumptions of 
future events. Future contribution requirements may emerge if those estimated assumptions 
are not borne out in practice or if different assumptions are agreed. Specific risks mitigated 
by the Trustees where possible in the investment strategy include: any changes in future 
expectations of price inflation, including reducing real rates of return; changes in the discount 
rate used to value the pension liabilities; interest rate risk on pension asset matching liabilities 
held; the return on assets being different to that assumed; concentration of plan assets in 
equities versus liquidity risk of holding assets which may be difficult to sell; counterparty credit 
risk including, but not limited to, fund manager risk; currency risks where investments are held 
in overseas markets via pooled investment vehicles; impact of bond rate on liabilities held; 
any movements in asset values not matched by similar movements in the value of liabilities, 
perhaps caused by pricing risks; and any unanticipated changes in life expectancy which 
may have a bearing on the size of the scheme liabilities. The investment strategy for the 
defined benefit pension scheme is discussed further in this note.

The return on plan assets excluding net interest was £(3,122,000) (2022: £573,000). The 
interest income on plan assets is calculated using the assets, market conditions and the 
long‑term expected rate of interest set at the start of the accounting period. The Company 
has contributed £Nil (2022: £Nil) as contributions to the CML Microsystems Plc Retirement 
Benefits Scheme and expects to contribute £Nil in the next accounting year.

Note: all assets listed above have a quoted market price in an active market or have been independently priced 
and reconciled to the underlining market prices and are valued using their bid values in accordance with IAS 19. 
The pension scheme no longer invests in bonds or property following a change in investment strategy. 
The Trustees’ investment strategy has the objectives to generate an appropriate level of 
investment returns to improve the financial position of the scheme (thereby improving security 
for its members); to manage cash flow requirements to ensure there are sufficient assets and 
cash flows available (to pay for member benefits as they arise); and to protect the financial 
position (in so doing limiting the scope for adverse investment experience impacting on 
members). The Trustees’ strategic asset allocation is determined after considering written 
advice from the investment advisor and is designed to strike the appropriate balance 
between these objectives. Liability matching assets are selected by the Trustees having 
regard to the nature of the scheme’s liability profile and are expected to react to changes 
in market conditions in a similar way to liabilities. Growth assets are expected to deliver 
long‑term returns in excess of liability growth. Current allocations are 17% of liability matching 
assets and 83% growth assets but this is monitored and rebalanced at the discretion of the 
Trustees and, moreover, on a day-to-day basis management of the assets delegated to the 
investment managers who have knowledge and experience for managing the investments. 
The Trustees, in conjunction with the investment advisor, regularly review each of the 
investment managers to ensure that the managers remain competent and assets continue 
to be managed in accordance with the managers’ mandates (the scheme objectives being 
implemented within an acceptable level of risk). 
Assets are held predominantly on regulated markets, as so defined in legislation. Any 
investments that do not trade on regulated markets are kept to a prudent level. To ensure 
the safekeeping of assets, ownership and day-to-day control of the assets is undertaken 
by custodian organisations which are independent of the sponsoring employer and the 
investment managers. Where pooled investment vehicles are used, the custodians will 
typically be appointed by the investment manager.

Options are granted with a fixed exercise price equal to the market price of the shares under option at the date of the grant. The contractual life of an option is ten years. Awards under the 
share option scheme are typically for all employees throughout the Group. Options granted under the share option scheme become exercisable on the third anniversary of the grant date. 
Options were valued using the Black‑Scholes model. The share option charge for the year was £234,000 (2022: £98,000). 
The fair value per option granted and the assumptions used in the calculation are as follows:
