 Strategic Report     10/11

Despite a volatile economic background and 
residual COVID disruption SDI achieved another 
record year, by a wide margin. The Group’s 
business model has again shown resilience in these 
challenging times, enabling the Group to grow sales 
and profits both as the wider economy entered 
the COVID-related recession and as it returned to 
more normal times. The Group added two new 
businesses during the year while existing businesses 
within the Group also performed well, with another 
year of strong organic growth.

ensure the Group has a good level 
of funding available for acquiring 
new companies, as well as investing 
in our existing companies and 
technologies.

Full-year Revenues of £49.7m have 
increased by 41.6% from 2021 and 
Adjusted Profit before Tax at £11.8m 
is up 58.9% from the previous year. 
Reported Profit before Tax has 
increased by 75.1% to £9.9m. This 
performance has been achieved 
through an exceptional 21.6% 
organic sales growth, demonstrating 
again continued commercial 
demand for the niche technologies 
SDI provides. Particularly of note, 
Atik Cameras delivered further 
growth with increased deliveries 
of specialised cameras providing 
the sensor function for PCR DNA 
amplifiers, and Astles Control 
Systems enjoyed record sales of 
control instrumentation for the 
beverage-can-making process. 
Further growth was generated by 
the newly acquired businesses and 
by the full year contributions of 
Monmouth Scientific and Uniform 
Engineering acquired in 2021.

Overall gross margin was slightly 
down on last year (63.8% compared 
with 65.2%) due to the increased mix 
this year of Monmouth Scientific and 
Uniform Engineering sales which 
are at lower than our average gross 

margin. We have generally been 
able to pass through increasing 
raw material costs. Our overheads 
have increased compared with 
last year given an increase in sales 
activity and selected investments to 
facilitate growth. Our experienced 
business managers remain focused 
on delivering products and 
services that represent good value 
to our customers while earning 
an appropriate return for our 
shareholders.

Cash flow has also been excellent, 
and metrics relating to returns on 
capital employed are also at record 
high levels.

Performance

On 5 January 2022, we completed 
the acquisition of Scientific Vacuum 
Systems (“SVS”), a UK manufacturer 
of physical vapour deposition 
equipment. On 24 March 2022 
SDI acquired Safelab Systems 
(“Safelab”), a UK manufacturer of 
fume cupboards. These businesses 
will be operated separately from 
our existing businesses. While SVS’s 
technology and markets served 
are mostly unrelated to our current 
portfolio, Safelab operates in a 
market with which we were already 
familiar. Both, however, fit perfectly 
within our acquisition criteria, and 
have become part of our Sensors 
and Control segment. Additionally, 
in August 2021 Monmouth Scientific 
acquired the trade and assets of the 
Clean Tent business of Moorfield 
Nanotechnology, for consideration 
of £150,000. Total consideration 
for the acquisitions is forecast to 
be approximately £12.0m, net of 
cash. We warmly welcome our new 
colleagues to the SDI Group.

These acquisitions were funded 
from cash and existing debt facilities. 
Both companies are profitable and 
contribute to earnings immediately, 
and indeed have performed very 
well since joining the Group. SDI’s 
continuing strong cash generation, 
along with its borrowing facilities, 

SDI Group plc Annual Report 2022

Strategy

The Group’s successful buy and 
build strategy is unchanged. We 
will continue to seek targeted 
acquisitions, funded by earnings 
and cash flows from our existing 
businesses where possible. The 
Group’s policy is to acquire small/
medium-sized companies within 
the science and technology sectors 
with a manufacturing bias. We seek 
to acquire businesses with high-
quality, niche technologies that have 
sustainable profits and cash flows and 
the potential to grow. 

We continue to service many sectors 
with SDI products, particularly in the 
life sciences and medical sectors. Our 
exposure to discretional consumer 
spending is limited. Our sales directly 
to government entities are not 
high, but government spending in 
healthcare and scientific research 
underpins a significant portion of 
our sales. Demand for Atik cameras 
for use in the fight against the 
COVID-19 pandemic continued 
strongly throughout this financial 
year and remains robust into the new 
financial year. We are confident that 
the demand related to the current 
pandemic will be replaced over time 
by demand for similar products in the 
broader life sciences domain.

To ensure we maintain the right level 
of operating capital and funding 
available for acquisitions, the Board 
has again decided not to pay a 
dividend this financial year but will 
keep this under review.

Corporate Governance

The Board takes its governance 
responsibilities very seriously. Our 
approach to our wide range of 
responsibilities is set out in the 
Corporate Governance section of 
our Annual Report, and as we grow, 
we expect to continuously improve 
governance towards the best practices 
required of a larger company. 

Further detail on Corporate 
Governance is available on the 
Group’s website www.sdigroup.com/
investors/governance

The Board, in common with our 
wider team and other stakeholders, 
is determined that the Group play its 
part in addressing climate change, 
and indeed that we reap the benefits 
of being part of the solution. We wish 
to avoid, however, both pointless 
box-ticking, where possible, and 
exaggerated claims. We are proud of 
the actions taken so far, and our focus 
is on taking tangible steps to reduce 
our carbon footprint and that of our 
products and services.

Board

Outlook

The Board of Directors remained 
unchanged throughout the year. 
Our CFO Jon Abell advised in 
January that he wished to retire in 
the Summer of 2022, and the Board 
followed a thorough process led by 
the Nomination Committee, leading 
to the hiring of Ami Sharma as his 
successor starting in August. Jon’s 
contribution to the development and 
growth of the SDI Group over his 
tenure has been fundamental. 

Isabel Napper has also decided to 
step down as non-executive director, 
which will be in August 2022 and the 
hiring process to find a replacement 
is well advanced. We wish Jon and 
Isabel all the best for the future.

Team

SDI now employs over 400 staff 
across its companies. Their skills and 
experience are key to the long-term 
sustainability of our businesses. To 
deliver another record year would 
not have been possible without their 
hard work and flexible approach as 
we return back towards normality. 
We operate with caution and 
discipline to protect our teams 
of employees and we offer our 
appreciation and thanks to them 
for their hard work and dedication 
throughout the year.

Over the last seven years, since 
the Group’s buy and build strategy 
gathered pace, the Group has 
grown its turnover from £8.4m 
to £49.7m and its reported profit 
before tax from £0.5m to £9.9m, 
through the excellent execution of 
a proven value-creating business 
model. While increasing shareholder 
returns consistently and substantially, 
we have also built capacity and 
capability to enable future growth.

The key growth drivers within our 
business remain organic growth 
and growth through acquisition. 
The Group is in a very strong 
financial position and has the 
resources and flexibility to support 
these key drivers. While mindful of 
the potential for further macro-
economic turbulence and despite a 
challenging external environment, 
FY2023 has begun well.

cancellations, face-to-face customer 
access difficulties and ongoing supply 
chain challenges, with difficulties 
in accessing some components at 
any cost and large price increases 
demanded for others in short supply. 
Customers resumed buying, and 
while the exceptional demand at 
MPB and Monmouth Scientific was 
no longer there, demand for cameras 
supplied into the PCR testing market 
remained high.

Against this background, I am 
pleased to report that our very 
flexible structure and the dedication 
of our staff across the Group have 
allowed us to maintain our growth 
rate, already strong in 2020-21 and 
previously, and we are reporting 
again record financial results.

Revenues and Profit

Overall revenues grew by 41.6%, of 
which 21.6% was organic growth 
and 20.0% was from the full year 
impact of the 2020-21 acquisitions 
of Monmouth Scientific and 
uniform Engineering and from the 
contributions of Scientific Vacuum 
Systems and Safelab acquired in 
the year. Adjusted Operating Profit 
grew by 56.8%, mainly resulting 
from the organic sales growth.

SDI’s digital imaging segment 
delivered 36.1% organic sales 
growth, with revenues at £21.5m 
and Adjusted Operating Profit at 
£8.5m, up 64.6%. At Atik Cameras, 
sales of cameras for PCR machines, 
previously expected to be essentially 
one-off due to COVID-19 demand, 
increased further, and in fact they 
are now expected to continue at 
least for the first half of 2022-23.  
At the same time, demand from our 
other camera customers has been 
recovering over the course of the 
year. Graticules Optics also achieved 
record sales, while sales at Synoptics 
were flat overall but 3% higher than 
in 2019-20.

The sensors and control segment 
grew sales by 46.0%, to £28.2m. 
Organic growth was 9.7%, and 
the remaining 36.3% growth was 
from the acquisitions of last year 
and this year. Adjusted Operating 
Profit grew 19.4% to £5.2m. Astles 
Control Systems grew substantially 
over the previous year, with a 
partial recovery of its global service 
revenue and very strong sales of 
equipment into new aluminium can 
production lines (linked to a slow 
transition away from plastic bottles). 
Sales of scientific and industrial 
chillers at ATC and of chemical 
sensors at Sentek saw good growth 
(last year they were flat on the 
previous year). MPB sales were 
slightly lower, without the benefit 
of sales of flowmeters for medical 
ventilators but were 13% higher 
than in 2019-20. Sales at Chell 
Instruments were also lower than in 
2020-21 when they benefited from 
a large equipment order received 
pre-pandemic. The level of sales 
at Monmouth Scientific, acquired 
in December 2020, continued at 
a high level, although the mix in 
demand has shifted away from 
standard biological safety cabinets 
(used to ensure operator safety 
and reduce contamination in 
COVID-19 test equipment) towards 
a more normal mix of custom/
modular fume cupboards, laminar 
flow cabinets and cleanrooms. 
Both Scientific Vacuum Systems 
(acquired in January 2022) and 
Safelab Systems (acquired in March 
2022) delivered revenues and 
profits which were consistent with 
our modelling at the time of their 
acquisitions.

Basic earnings per share increased 
by 56.5% from 4.81p to 7.53p; fully 
diluted earnings per share also 
improved by 57.9% to 7.23p  
(2021: 4.58p). 

Mike Creedon

Our financial year from May 2021 to 
April 2022 coincided with the second 
year of the COVID-19 pandemic, 
under which most restrictions to 
normal life and work were lifted in 
the UK (with limited and temporary 
restrictions put back in place for the 
milder Omicron wave), and from 
February 2022 the start of the Ukraine 
conflict (which has had limited impact 
on the Group). 

In the previous year (2020-21), 
while all of our businesses had 
remained in production throughout, 
with some exceptions where their 
customers reduced their purchases, 
and all businesses had to cope with 
uncertainty, logistics challenges, 
employee safety and well-being 
concerns, and travel restrictions. The 
exceptional cases, notably at our MPB 
and Atik Camera businesses, and at 
Monmouth Scientific (acquired in 
December 2020), had additionally the 
welcome challenge of significantly 
increased demand for products 
related to the diagnosis and treatment 
of COVID-19. 

This financial year (2021-22) was 
thus characterised by a substantial 
progression towards normality, 
although certainly tempered by 
persistent travel restrictions (especially 
outside of Europe), trade fair

safety in their manufacturing facilities 
and their businesses to thrive. 

This year we have focused much 
attention on embedding last year’s 
acquired businesses into the Group, 
and we have acquired two additional 
high-quality and profitable UK-
based businesses, extending our 
technology and customer base and 
providing further scope for future 
organic growth.

On 5 January 2022, the Group 
acquired 100% of the share capital of 
Scientific Vacuum Systems Limited 
(“SVS”), for total consideration 
estimated at £5.5m, of which £4.5m 
has been paid in cash and the 
remaining £1.0m is contingent on 

SVS achieving expected profit for 
the year to 30 September 2022. 
On the date of the acquisition, 
SVS had £1.25m of cash in 
hand. SVS specialises in custom 
Physical Vapour Deposition (PVD) 
systems for the deposition of 
thin film coatings typically on 
semiconductor wafers, for use in 
scientific research, industrial and 
semiconductor manufacturing 
applications, and is the market 
leader in the manufacture of 
production sputter coaters for 
premium brand razor blade 
coating. SVS brings considerable 
technology and engineering 
expertise to the Group in high 
vacuum and PVD applications, 
as well as blue chip customers, 
and may be a springboard for 
future acquisitions. SVS is based in 
Finchampstead, Berkshire.

On 24 March 2022, the Group 
acquired 100% of the share 
capital of Safelab Systems Limited 
(“Safelab”) for £8.5m (including 
£0.2m in SDI Group shares, £5.9m 
in cash paid before the year end 
and £2.4m in cash paid after the 
year end). On the date of the 
acquisition, Safelab had £0.8m 
of cash in hand. The company 
owns its main manufacturing 
building valued at £1.4m. Safelab 
produces high specification fume 

cupboards and similar cabinets, 
for both commercial and research 
laboratories and with a special focus 
on the education sector which 
requires versatile and fully featured 
ducted cabinets often specified in 
newly built or refurbished laboratory 
facilities. Safelab is based in Weston-
Super-Mare. The acquisition follows 
the Group’s December 2020 
acquisition of Monmouth Scientific 
which manufactures clean rooms, 
fume cabinets and safety cabinets 
and is based in Bridgwater. The 
Group will maintain the identity 
and autonomy of both companies 
in their current locations, but the 
businesses are actively seeking and 
finding areas of co-operation to 
reduce costs and enhance their 
total customer offer. Our Uniform 
Engineering business is a supplier 
of sheet metal fabrications to both 
Monmouth Scientific and to Safelab.

We have funded the cash elements 
paid for both acquisitions from our 
existing cash resources and from our 
revolving credit facility with HSBC 
UK Bank. The acquired companies 
contributed £1.7m of revenues to 
the Group this year and as expected, 
both acquisitions have been earnings 
enhancing to the Group in 2021-22 
immediately following initial 
acquisition-related costs.

We have a clear development strategy and our success comes from  
our culture, which fosters creativity, teamwork and co-operation

...with the Right 
  People, Products  
  & Performance

Operations

We have now learnt to live with the 
pandemic, and although enhanced 
safety measures are still in place 
and some staff work some of their 
days from home, our focus across 
the Group is very much on working 
closely together and with our 
customers to build for the future.

In common with manufacturing 
industry across the world, and 
perhaps especially in the UK 
following Brexit, the pandemic 
is causing supply chain issues to 
all of our businesses, and a tight 
labour market is further forcing 
cost increases which have recently 
been compounded by the impact of 
Russia’s invasion of Ukraine. We have 
been delighted with the response 
from our businesses’ management 
and staff who have worked tirelessly 
to find solutions to component 
shortages, and the results can be 
seen in our record levels of sales and 
profit. We now look forward to an 
expansion of new product launch 
activity, by our customers and by our 
own businesses, and we believe this 
brings the Group new opportunities 
to gain market share following a 
period in which the focus has been 
on supplying existing products.

Our rolling programme of 
upgrading manufacturing facilities 
across the Group continued 
with the completion in March of 
the consolidation of Monmouth 
Scientific’s production and 
administration activities from several 
buildings to a single purpose-
built site in Bridgwater, the start 
of a substantial refurbishment of 
the Graticules Optics factory in 
Tonbridge, and the doubling of 
engineering and manufacturing 
space at Astles Control Systems 
in Princes Risborough. Such 
investments typically have a very 
good payback, as they are justified 

by the capacity increase but bring 
many other benefits including 
efficiency, staff comfort, product 
quality and image.

While face-to-face sales activity, 
including trade fairs and exhibitions, 
remained difficult (although it 
has picked up substantially in the 
last couple of months), we have 
continued to make good progress 
with website enhancement, on-line 
sales, virtual selling techniques and 
social media activity, and we have 
been able to leverage our capability 
across the Group.

During the 2020-21 year at 
Atik Cameras, we strengthened 
the management team at both 
company sites, near Norwich for 
overall business management, 
sales and marketing and research 
and development, and near Lisbon, 
Portugal, for manufacturing, 
logistics, account management 
and finance. During the 2021-22 
year, we have further developed the 
organisation so that all invoicing to 
customers is now direct from our 
Portuguese operation and the UK 
organisation provides management, 
sales and marketing and R&D 
services to Portugal. This has been 
very well received by customers.

When acquiring businesses, it is 
imperative for us that they have a 
strong management team usually 
led by the founder of the business. 
This year two of our managing 
directors decided to step down 
but I am pleased to say, still 
continue in consultancy roles. Steve 
Chambers, one of the founders of 
Atik Cameras, stepped down at the 
beginning of April 2022. He was 
replaced by Panos Kapetanopoulos, 
who was the R&D director. David 
Pomeroy decided to step down 
in December 2021 at Monmouth 
Scientific and was replaced by 
Alan Holcombe, who also remains 

Managing Director at Uniform 
Engineering. I wish Panos and Alan 
well in their new roles and am certain 
they can be successful with the 
support of the SDI directors and their 
fellow subsidiary directors.

Cash and Liquidity

SDI has a strong balance sheet with 
current year-end gross cash at more 
than £5.1m, and £16.0m of undrawn 
bank facility, which remains available 
(unless extended) until November 
2024. The Group therefore has 
sufficient funds that can be used, with 
its steady cash flow, to acquire new 
companies and invest in our current 
portfolio of profitable businesses. 

Trading Outlook

Our businesses remain busy, and 
several are operating at full capacity 
with their current staffing. Finding 
good staff and circumventing supply 
chain issues are now part of daily 
business, and our managers have 
demonstrated their ability to solve 
these challenges and more.

We have budgeted for organic 
growth, and, although mindful of a 
possible consumer-led recession 
and levels of inflation that have been 
absent for many years, we have had 
a good start to the 2022-23 financial 
year and are confident that we can 
continue to trade profitably over the 
coming months.

The market for acquisitions appears 
buoyant, and SDI expects to acquire 
additional businesses in the 2022-23 
financial year.

Chief Financial Officer’s Report 

 Strategic Report     18/19

SDI Group revenues for the year were £49.7m, 
compared with £35.1m in 2020-21, an increase 
of 41.6%. Sales growth from acquired businesses, 
including sales of Monmouth Scientific and 
of Uniform Engineering in the periods to their 
acquisition anniversaries and post-acquisition sales 
of Scientific Vacuum Systems and Safelab Systems, 
contributed £7.0m, while organic sales growth 
was £7.6m or 21.6%. This builds on top of organic 
sales growth in 2020-21 of 19%.

Gross profit increased to £31.7m 
(2021: £22.9m), with margin 
reduced to 63.8% (2021: 65.2%) 
due to significant product mix 
changes including lower than 
average gross margins at recently 
acquired companies.

Operating profit for the year was 
£10.2m (2021: £5.9m) and Adjusted 
Operating Profit (AOP) was £12.1m 
(2021: £7.7m) before reorganisation 
costs, share-based payments, 
acquisition costs and amortisation 
of acquired intangible assets,  
an increase of 56.8%. Significant 
drivers of the increase were the 
organic sales increase, plus the 
added contributions of the  
acquired businesses.

Investment in R&D

Under IFRS we are required to 
capitalise certain development 
expenditure, and in the year ended 
30 April 2022, £0.4m (2021: £0.4m) 
of cost was capitalised. Much of the 
work of our growing R&D teams 
does not qualify for capitalisation 
and is charged directly to expense. 
Amortisation for 2022 were £0.4m 
(2021: £0.4m). The carrying value of 
the capitalised development at 30 
April 2022 was £0.9m (2021: £1.0m) 
to be amortised over 3 years.

Reorganisation

The Board carried out a thorough 
review of the operations and cost 
structure of the Group and this 
gave rise to £0.1m (2021: £0.1m) 
of reorganisation costs in the year, 
which should bring benefits in the 
current year.

Acquisition Costs

The Group incurred costs of £0.3m 
(2021: £0.2m) in relation to stamp 
duty, legal fees, and other advisor 
remuneration for the acquisitions 
completed in the year.

Financing

Financing costs totalled £0.3m 
(2021: £0.3m), including interest 
costs estimated within leases.

Taxation

Taxation charge for the year was 
£2.3m (2021: £0.9m). Included in the 
charge is £0.7m representing  
the increase in net deferred tax 
liabilities due to the enacted change 
in UK taxation rates (from 19% to 
25%) in force from March 2023.  
The remainder of the increase 
results mostly from increased 
profitability. Excluding the rate 
change on the deferred tax position 
the net tax rate was 16.3% (2021: 
16.6%). The Group continues to 
benefit from R&D tax credits.

Revenue and Profits

From the outset of the COVID-19 
pandemic, in 2020-21, our Atik 
Cameras business received 
substantial orders from an existing 
OEM customer for cameras 
designed into the customer’s 
PCR instrument. At the time, we 
considered these to be one-off 
orders, and we viewed follow-on 
orders from the same customer  
in the same light. Further and larger 
orders have followed in the 2021-22 
year, and sales are continuing at a 
high rate in 2022-23. The expansion 
of Atik Cameras sales represents 
a large proportion of the Group’s 
organic sales growth in both 
years. We can no longer consider 
these sales to be one-off, but it 
is also prudent to assume that at 
some point the demand for PCR 
instruments will normalise at a  
lower level. However, having 
demonstrated the efficacy and 
competitiveness of its camera, we 
also expect Atik to successively 
pursue a wider market for its 
products. Organic growth from 
other portfolio companies  
averaged 9%.

Sales 2022

Our investment in fixed assets 
increased to £1.4m (2021: £0.6m) 
with significant investments in 
company-owned fixtures to our 
new leased building at Monmouth 
Scientific and at Graticules Optics.

As in prior years, our biggest 
investment was in the acquisition 
of new businesses, with £12.0m 
deployed on a cash-free basis 
(including contingent consideration) 
of which £0.2m in shares (2021: 
£6.6m of which £0.2m in shares). 
At the end of the year contingent 
consideration of £3.4m was 
outstanding (2021: £2.35m), of 
which £2.4m has been paid since 
the end of the year to the sellers 
of Safelab Systems and £1.0m 
remains outstanding relating to the 
acquisition of SVS, to be settled after 
30 September 2022.

Funding

Our investments were financed out 
of our own cash flow, except for 
the issue of 117,716 shares valued at 
£200,000 as part payment for our 
Safelab Systems acquisition. Having 
started the year with net cash of 
£0.7m (£3.8m of cash less £3.1m of 
bank loans) we closed the year with 
net cash of £1.1m (£5.1m of cash less 
£4.0m of bank loans).

On 1 November 2021 we renewed 
and expanded our committed loan 
facility with HSBC from £7.4m to a 
£20m revolving loan facility, with 
a further accordion option of an 
additional £10m (at the discretion 
of HSBC), and with repayment date 
of November 2024 extendable for 
two further years. The new facility 
has been tailored to our business 
model with fewer restrictions on 
acquisitions and allows for higher 
leverage if necessary.

Earnings per Share

Diluted earnings per share for the 
Group was 7.23p (2021: 4.58p). 
Adjusted diluted EPS, an alternative 
performance measure which 
excludes certain non-cash and 
non-recurring expenses was 8.71p 
(2021: 5.97p), an increase of 45.8%.

Cash Flow and Working 
Capital

During the year the Group 
generated cash from operations  
of £14.7m (2021: £11.7m). In the 
prior year, we benefited from an 
increase of £3.2m in customer 
advanced payments received, 
largely related to COVID-19 related 
contracts in Atik. The balance of 
these is £1.5m lower at 30 April 
2022 compared with a year ago. 

Taxes paid have increased to £1.3m 
(2021: £1.2m). The lower payments, 
relative to £2.5m taxes charged to 
the income statement, result partly 
from the tax deductions available 
to the Group on exercise by 
directors and employees of share 
options. As noted above, taxes on 
the income statement also include 
a £0.7m non-cash charge to 
update deferred tax balances to the 
enacted future UK tax rate of 25%.

Strategy & Key Performance Indicators

 Strategic Report     20/21

Key Performance Indicators

A range of financial key performance 
indicators are monitored for each 
business and for the Group as a whole 
on a monthly basis against budget 
and over time by the Board and by 
management, including order pipeline, 
revenue, gross profit, costs, adjusted 
operating profit, and cash. 

In support of our acquisition strategy 
as outlined above, we monitor our 
acquisition pipeline, including any 
prospects that fail to progress. Post-
acquisition, the Board discusses 
integration progress, and monitors 
financial performance against our 
initial plans. Over a longer period, we 
monitor the return on total invested 
capital of all of our businesses.

The Board regularly discusses progress 
in all major research and development 
and other projects with project and 
business leaders, including with respect 
to cost, timelines and adherence to the 
projects’ initial objectives.

Additionally, the Board reserves a 
specific agenda item for discussion of 
health and safety and other employee 
welfare-related issues.

SDI Group is an AIM-quoted group 
specialising in the acquisition 
and development of a portfolio 
of companies that design and 
manufacture products for use in 
digital imaging and sensing and 
control applications in science, 
technology and medical markets. 
Corporate expansion is being 
pursued, both through organic 
growth within its subsidiary 
companies and through the 
acquisition of high-quality 
businesses with established 
reputations in global markets.

The Board believes there are many 
businesses operating within the 
market, a number of which have 
not achieved critical mass, and that 
presents an ideal opportunity for 
consolidation. This strategy will 
be primarily focused within the 
UK but, where opportunities exist, 
acquisitions in Europe and the 
United States and elsewhere will also 
be considered, particularly if these 
also enable geographic expansion of 
our existing businesses. 

We intend to continue to buy stand-
alone businesses as well as smaller 
entities and technology acquisitions 
which bolt onto our existing ones. 
Our track record over the last eight 
years has been good, with fifteen 
businesses acquired across our 
digital imaging and sensors and 
controls segments.

An important element of our 
strategy is that we are known to be a 
good acquirer, able to help sellers to 
achieve a sale quickly and easily, and 
without surprises.

We keep a lean headquarters, and 
our businesses are run by seasoned 
local management with broad 
discretion within defined limits. 
Our aim is to grow them, profitably, 
and we seek to provide them with 
the resources necessary to grow. 
Acquired businesses often find that 
they can grow faster within the SDI 
Group than they were prepared to 
do under private ownership, and 
they are able to learn from and share 
experience with other companies in 
the Group.

Our current businesses fall broadly 
into two segments, which we call 
Digital Imaging and Sensors & 
Control, and within these groupings 
there are significant commonalities 
of applications, industries served and 
technologies employed. This provides 
additional opportunity for knowledge 
sharing, which we encourage.

Growth in revenues and profit 
within our businesses depends on 
both technology advancement 
and seeking new customers, often 
by expanding geographical reach, 
and the Board sees geographical 
expansion as a driver of organic 
growth for the future.

By lowering the cost of capital 
of businesses we acquire and 
by facilitating their profitable 
growth, our business model has 
demonstrated that it can provide 
good returns to shareholders and 
can be scaled into the future.

Section 172(1) Report

 Strategic Report     22/23

Statement by the directors in 
performance of their statutory  
duties in accordance with s172(1)  
of the Companies Act 2006

When making decisions, the directors 
of SDI Group plc must act in the way 
they consider, in good faith, would be 
most likely to promote the success 
of the Company for the benefit of its 
members as a whole (having regard  
to the stakeholders and matters set 
out in s172(1)(a-f) of the Companies 
Act 2006). 

The directors are committed to 
developing the Group to create value 
for shareholders over the long term 
and believe that attention to the 
interests of all stakeholders will  
provide the best platform for  
sustained value creation.

Here we provide some detail regarding 
our engagement with key stakeholders, 
our understanding of their interests, 
and our actions and decisions taken 
which may affect them.

Shareholders and their 
Representatives

SDI Group plc is quoted on the AIM 
market and has shareholders ranging 
from investment funds and high net 
worth individuals to retail investors, 
directors and employees and 
former employees. All shareholders 
are entitled to share equally in the 
Group’s success, and we aim to 
provide all with the information they 
need to understand the progress of 
their investment. We believe that a 
mixed shareholder base provides 
benefits to all in maintaining liquidity 
in the shares.

In addition to public announcements 
made, directors meet from time 
to time with some of the Group’s 
larger shareholders and potential 
shareholders to discuss the state of 
the Group, usually following annual 
or interim results announcements 
and with the presence of our 
Nominated Advisor. These meetings 
are important in providing large 
investors with comfort for their 
investment decisions and are 
for many a requirement prior 
to investing. These meetings 
may be held face-to-face or by 
videoconference.

In recent years, we have provided 
via a videoconference platform the 
same presentation to members of 
the public, with the opportunity 
to ask questions of the presenting 
directors, and this has enjoyed 
a good level of attendance. We 
also welcome requests from all 
shareholders to speak with directors, 
and we will usually be able to 
accommodate that.

These meetings do not give 
attendees any insider information 
and presentations made are excerpts 
from publicly available documents 
such as this Annual Report. 

Directors may occasionally consult 
with some of our larger shareholders 
on matters of executive benefits, to 
ensure that these are aligned with 
the expectations of the market.

The directors keep the payment of  
a dividend under review. We are 
aware that different shareholders 
(and current non-shareholders) may 
have different dividend appetites,  
and we cannot please everyone.  
Our judgement to date has been 
that, as a growth company with 
a track record of creating value 
through acquisitions, funds were 
better reserved for investment. 

Customers and Suppliers

SDI Group is organised as a 
constellation of individual operating 
businesses, each with its own 
general management, and customer 
and supplier bases. Our engagement 
with customers and suppliers 
generally takes place within those 
businesses. Some customers and 
suppliers are common to several 
of our businesses, although we 
may deal with different divisions 
of the same group. The directors 
encourage our businesses to deal 
correctly with their customers and 
suppliers, and to look for long-
term relationships that can add 
value to all parties. Our businesses 
report on key relationships to our 
executive directors and in their 
reports to the wider Board, and we 
look for opportunities to expand our 
relationships with good customers 
and suppliers across the Group. 
During the course of the COVID-19 
pandemic, the Group took specific 
care to pay its suppliers to agreed 
terms in order to provide certainty 
during the pandemic.

We aim to develop new products 
and technologies that satisfy future 
customer needs and provide the 
highest quality and most reliable 
products for the markets we serve.

Employees

Acquisition Partners

For SDI Group, acquisitions are not 
one-time events, but a repeatable 
process. We seek to make the 
process as easy as possible for 
sellers and for their advisors to 
realise their goals. Our management 
of the businesses post-acquisition 
is also a key factor in enhancing our 
reputation as a good acquirer. By 
treating sellers openly and fairly, and 
by executing on our commitments, 
we seek to remain the acquirer of 
choice for businesses that will fit well 
into the Group. 

Our business is built on the hard 
work, knowledge, skills and 
experience of staff across the 
Group. We expect them to go the 
extra mile in looking after our other 
stakeholders, and they do so. Our 
commitment is to look after them 
fairly, both in economic terms and 
in providing a stimulating working 
environment where they can use and 
develop their capabilities to the full. 

Executive directors of SDI Group 
engage with employees across the 
Group during regular visits to all 
locations, and the Board’s policy is 
to rotate its meetings around the 
locations so that all directors can 
meet with staff. The Board receives 
monthly reports from the Group’s 
operating businesses which include 
sections on staffing matters and 
reserves specific agenda slots for 
staff and health and safety matters at 
each regular meeting. 

Key staff remuneration, and 
remuneration policy for the wider 
Group, is decided by directors, 
and our aim is to pay people 
competitively and provide additional 
reward for exceptional performance. 

The culture at SDI Group, as 
experienced by our staff, is 
generally that of a successful 
small business, which is the recent 
history of each of our operating 
businesses. As part of the SDI Group, 
however, opportunities for career 
development and learning from 
other businesses can be enhanced, 
and we look for ways to develop 
our staff across the Group. Staff in 
our operating businesses are also 
interested and informed about the 
activities and performance of the 
wider Group.

Principal Risks & uncertainties

Sustainability is at the core of all that we do

SDI Group is here for the long term. 
Our directors expect it will long 
outlast them, and our owners should 
know that most of its value lies 
beyond the forecastable horizon. 
We believe that our business 
model can progress and develop 
indefinitely, subject to our nurturing 
the stakeholders that help make 
us successful. We would like those 
stakeholders to remain with us for a 
long time on our journey.

Consequently, sustainability is not just 
on our agenda, it is our agenda.

The Environment

SDI Group recognises that the 
significant environmental challenges 
facing the world, including man-
made climate change, deforestation 
and habitat loss, and water quality and 
availability, must be addressed by all 
businesses worldwide. We understand 
that our trading activities have an 
environmental impact and that we 
must make real changes to reduce 
any negative impact.

SDI’s current businesses are not big 
polluters, and we do not expect 
to acquire businesses that have a 
significant carbon footprint, in keeping 
with our sustainability agenda. At 
the same time, we believe that our 
businesses can and do contribute 
to reducing society’s environmental 
impact by providing technological 
products that are more accurate, 
consume less energy and other 
inputs, and enable better science than 
those available in the past. We can be 
proud of the portfolio, but we must 
continue to innovate.

In keeping with our devolved 
operating model, our actions to 
mitigate, improve and innovate our 
environmental impact take place 
within our businesses, which respond 
to the demands of the markets 

they operate in, to their customers, 
their employees and their local 
communities, all of whom have a stake 
in a more sustainable future. Initiatives 
implemented in the last year have 
included the installation of solar panels 
at Monmouth Scientific’s new factory.

SDI operates a flat structure, and we 
do not currently attempt to track and 
consolidate environmental KPIs across 
the group as this would be a significant 
escalation of reporting requirements 
for little, if any, environmental impact. 
Our HQ role is one of encouragement 
and idea-sharing, and of approving 
investments whose sustainability 
impact may not be fully quantified 
financially. This may have to change 
in the future if SDI is covered by 
additional reporting requirements.

Social Matters

SDI Group seeks to provide, in its 
businesses, a challenging, enjoyable, 
safe and caring environment for 
its employees, so that they can 
contribute, develop and remain with 
the Group for the long term.

We comply with all relevant 
legislation, obviously including:

l  Health and safety, where the Board 
reviews monthly reports from all of 
its businesses to ensure root causes 
of any issues are addressed.

l  Anti-bribery and corruption. The 
Group operates on an ethical basis 
in all of its activities and takes all 
reasonable steps to ensure bribery 
and corruption are prevented by 
those working for the Company or 
associated with it, including third 
parties and agents.

l  Equal opportunities. SDI Group 

is a committed equal opportunity 
employer. We endeavour to treat 
all employees equally and fairly and 
encourage them to apply these 

principles themselves. We support 
staff training, appraisals and 
personal development and we 
seek to maintain a good working 
environment. We use professional 
advisors to ensure our personnel 
practices are up to date with legal 
requirements.

l  Disabilities. The Group gives 
full and fair consideration to 
applications for employment 
from disabled persons where 
the requirements of the job 
can be adequately fulfilled by a 
handicapped or disabled person. 
Employees who become disabled 
are provided, where practicable, 
with continuing employment 
under normal terms and 
conditions and are provided with 
training and career development 
where appropriate.

l  Modern slavery and human 

trafficking. The Group does not 
tolerate any kind of coercive 
labour practices and strictly 
adheres to standards required 
under all relevant employment 
legislation.

We are mindful that the way we 
operate our existing businesses and 
treat our employees influences our 
attractiveness as an acquirer of new 
businesses, and provides a strong 
differentiator against competing 
trade or financial bidders.

Governance

Governance matters are discussed 
as required in the relevant section 
of this report. The Group’s aim is to 
always act responsibly, ethically and 
in the protection of shareholders’ 
and other stakeholders’ interests, and 
to continue to review and evolve its 
governance processes as it grows 
in advance of expectations without 
simply ticking the box.

The following represent, in the 
opinion of the Board, the principal 
risks and uncertainties of the business. 
It is not a complete list of all the risks 
and uncertainties, and the priority, 
impact and likelihood may change 
over time.

Acquisitions
Acquisitions are a key element of our 
strategy, and the failure to identify and 
prosecute acquisition opportunities 
would impact future growth in 
profit and share price. The Group 
spends significant time and energy in 
identifying acquisition opportunities 
and receives suggestions from various 
sources as well as directly or through 
our own businesses and management. 
These are carefully filtered, and the 
most attractive ones are managed to a 
possible successful conclusion.

An additional important risk is that 
an acquisition does not provide the 
financial return expected. The Group’s 
disciplined due diligence process  
helps to avoid this, but the Group 
is also able to marshal resources 
in support of an acquired entity’s 
management team to help them 
improve performance as necessary.

Dependence on key distributors  
and OEM customers
Failure to effectively manage 
our distribution channels could 
damage customer confidence and 
adversely affect our revenues and 
profits. Additionally, in several of our 
businesses, significant amounts of our 
sales are to a small number of OEM 
customers, and any reduction in their 
end product sales or in our share of 
their purchases would impact our 
revenues and profits.

In order to mitigate this risk the Group 
dedicates significant resource to 
maintaining close relationships with 
our distributors and OEM customers, 
including at Group level, and we aim to 
provide them with products and service 
that match their needs.

Competition and technological  
obsolescence
Competition from direct competitors or 
third-party technologies could impact 
upon our market share and pricing. 

In order to mitigate this risk the Group 
continues to invest in researching its 
markets and continues to offer new 
products in response to changing 
customer preferences. In addition, 
the Group invests in research and 
development to maintain its  
competitive advantage.

Supply chain failures
Recent events including Brexit, the 
COVID-19 pandemic and the Russian 
invasion of Ukraine have combined to 
make supply chain robustness a key 
competitive advantage. There may be 
further logistical disruptions resulting 
from the reconfiguration of borders, 
possibly combined with other supply 
chain disturbances due to the COVID-19 
pandemic, shipping issues, ransomware 
and geopolitical events.

The Group has taken appropriate steps 
to minimise disruption, including some 
expansion of stocks, and has cooperated 
with customers to ensure continuity 
of their supply chain. The Group has 
also conducted a detailed review of the 
robustness of cyber security measures 
which has resulted in investment in  
more robust systems and procedures.

Recruitment and staffing
If the Group fails to recruit and retain 
individuals with the appropriate skills  
and experience its performance may 
suffer. To ensure the Group retains the 
highest calibre staff it has implemented  
a number of schemes designed to  
retain key individuals, both financial and 
non-financial, including bonuses and 
share option schemes.

COVID-19
The effects of COVID-19 have reduced 
over recent months but this is not 
uniform across the world and there is 
a risk that future developments do not 
follow the same course as those seen in 

earlier phases, and that sales orders 
are reduced, production operations 
are disrupted, or supplies of key 
components are interrupted.

Over the course of last year and 
2020-21, each of SDI’s businesses has 
been profitable and cash-generative, 
and this suggests that the business 
model of SDI Group is resilient to 
similar risks. The Group remains alert 
to continuing risks.

Currency and foreign exchange
As with the majority of international 
companies, the Group’s UK and 
overseas businesses purchase goods 
and services and sell some of their 
products in non-functional currencies. 
Where possible, the Group nets such 
exposures or keeps this exposure to 
a minimum. The Group’s principal 
exposure is to US Dollar and Euro 
currency fluctuations against Pound 
Sterling, and in both currencies, we 
sell more than we purchase and we 
have a higher level of debtors than 
creditors. This typically means that 
a relative devaluation of the Pound 
results in exchange gains and an 
improvement in competitiveness, 
whereas a revaluation has the 
opposite effects. 

We have never hedged our exposure 
using financial derivative products, 
but we do have some activity in both 
Europe and USA, including a factory in 
Portugal, which acts a partial natural 
hedge. However, we have established 
a procedure for the approval of simple 
hedging transactions if conditions 
require them. We keep cash balances 
in Euros and Dollars to a minimum 
and may take out loans under our 
revolving credit facility in Euros and 
Dollars, to reduce our net exposure 
to those currencies. If the Pound 
strengthens significantly, we will 
review all opportunities to realign our 
costs to the changed circumstances.

Liquidity
A review of the Group’s exposure to 
liquidity risk is provided in note 26.

responsibility for conducting Board meetings and making sure that there is effective and timely communication to our 
shareholders. In my role as Chair, I also provide advice, counsel and support to the executive.

The 2018 QCA Corporate Governance Code

The AIM Rule 26 introduced during our 2019 year requires the Group to follow a recognised corporate code of 
governance. The Board, after due consideration, agreed to follow the 2018 QCA Corporate Governance Code after 
concluding that it was the one best suited to SDI’s business, aims and ambitions. The Board believes that the Group 
complies with the Code, but is committed to continuously improving its governance over time.

Here we explain how we implement the 10 principles of the QCA Corporate Governance Code in practice.

7

Principle

Commentary

The Board has a shared view of SDI’s purpose, business model and 
strategy. Our vision is to develop our existing technologies and to grow 
through strategic acquisitions. We believe that acquiring companies 
which complement the capabilities within SDI will promote organic 
growth and give us the opportunity to explore challenges and new 
markets within the fast-evolving science and technology sectors.

3   

Taking account of 
wider stakeholder and 
social responsibilities 
and their implications 
for long-term success

Responsibility for shareholder liaison rests principally with our CEO 
supported by our CFO. However, all our Board members attach a 
high degree of importance to providing shareholders with clear and 
transparent information on the Group’s activities, strategy and  
financial position. 

Details of all 
shareholder 
communications  
are provided on  
our website

The Board holds meetings with institutional investors and other large 
shareholders following the release of the interim and financial results, 
and in recent years has also presented to smaller shareholders and the 
general public using the same material with opportunity to ask questions 
and provide feedback to the Board. 

We regard our Annual General Meeting as a good opportunity to  
engage directly with shareholders through a question-and-answer 
session. We provide the market and shareholders with the results of  
AGM and GM voting via RNS and other communication channels 
including the Group’s website.

SDI’s vision involves encouraging our subsidiary businesses to work 
together to help advance medical and scientific knowledge, increase the 
technical capabilities of industry and ultimately improve the standard of 
living of the population as a whole.

As well as that overarching purpose, the Board recognises that  long-
term business success relies on good relations with a range of different 
stakeholder groups both internal and external such as staff, suppliers  
and customers. 

We also seek to understand the impact our business activities have on  
the communities in which we operate and consider our corporate  
social responsibilities and how these issues are integrated into our  
long-term strategy. 

We encourage feedback from all our stakeholders and where appropriate 
use that feedback to shape our future direction e.g., new methods or 
product offerings.

Maintaining the Board 
as a well-functioning,

Commentary

We have addressed the principal risks we face by the appointment of an 
experienced executive team supported by experienced non-executive 
directors and a team of appropriately qualified professional advisers.

Our executive directors are closely involved in the day-to-day operations of 
the Group and of our operating subsidiaries and report to the Board in detail 
at regular intervals. Relevant papers are distributed to members of the Board 
in advance of Board and Committee meetings. Detailed financial reports of 
the Group’s financial performance are also provided on a regular basis. 

Our directors’ knowledge and understanding of the Group is further 
enhanced by on-site visits to operational units; directors also receive 
presentations from senior management on the performance and strategies 
of their business units. 

We have included in our strategy meetings with our operating subsidiaries 
a specific agenda item on risk management, to understand individual 
business risks and to confirm appropriate mitigating actions.

Directors also have the contractual right to take independent professional 
advice on any matter – at SDI’s expense – if they deem it necessary in 
order to carry out their responsibilities.

Our Board consists of two executive directors (CEO and CFO) together with 
the Chairman and two independent non-executive directors. We believe 
this to be a good balance for a business of our size. Due to their working 
backgrounds and professional experience the non-executive directors 
provide a solid foundation for good corporate governance for the Group. 
They are also independent of management and ensure that no individual or 
group dominates the Board’s decision-making process. 

To ensure the Board functions well, our non-executive directors are 
requested to attend eleven Board and Board Committee meetings per year. 
They are also required to be available at other times between meetings 
when necessary for face-to-face and phone/web meetings. We also hold 
an annual strategy meeting at which directors’ attendance is mandatory. 
Each non-executive director must demonstrate that they have sufficient 
time to devote to our business.

To support the Board, we have put in place Audit, Remuneration and 
Nomination Committees all of which have agreed formal terms of reference.

Ensuring the directors 
have the necessary 
up-to-date experience 
skills and capabilities

Our directors have been chosen because of the skills and experience they 
offer. Of our five directors one is female and four are male. All have listed 
company experience and one was the CEO of an investment bank, three 
are accountants, one a lawyer. 

Our directors attend industry and regulatory learning and networking 
events in order to keep up to date with relevant developments.

Directors are presented

Evaluate Board 
performance 
based on clear and 
relevant objectives, 
seeking continuous 
improvement

We undertake annual monitoring of personal and corporate performance. 
The responsibility for assessing and monitoring the performance of the 
executive directors lies with the independent non-executive directors. 

Agreed personal objectives and targets are set each year for the executive 
directors and performance measured against these metrics.

Again this year we performed a formal Board evaluation process. The 
process was led by our Chairman assisted by the Chair of the Nominations 
Committee and required directors to answer a set of questions setting out 
their views on the effectiveness of the Board and on the value of their Board 
contributions. The results of that assessment process were used by the 
Chairman to facilitate discussions with each individual director and with the 
Board as a whole. The questions were based around issues arising from the 
ten principles of the QCA Code and the results have assisted in continuing 
our focus on strategy and risk management.

Commentary

Further Information

We believe it is the responsibility of the Board and senior leaders to 
ensure that the culture of our organisation is based on ethical values and 
behaviours. As well as leading by example, our ethics-based culture is 
promoted through our business behaviours, decisions, processes and 
operations, as well as the management of the risk of ethical misconduct.  

In addition, we have mechanisms to support high ethical standards –  
e.g., for raising concerns and reporting misconduct. We also aim to 
include ethical criteria in recruitment and in performance appraisals and 
have detailed policies relating to important issues such as discrimination, 
harassment, bribery and corruption, and conflicts of interest. We expect  
all our staff to adhere to these high standards. 

We are keen to invest in our people not just our companies. With that 
in mind we seek to make our workplaces a better environment and to 
encourage all our staff to undergo relevant training and development.

Our non-executive directors scrutinise the performance of  
management against the Group’s objectives and also monitor the  
reporting of performance.

The Board has considered mechanisms by which the business and the 
financial risks facing the Group are managed and reported to the Board. 
The principal business and financial risks have been identified and control 
procedures implemented. The Board acknowledges its responsibility for 
reviewing the effectiveness of the systems that are in place to manage risk. 

To achieve this aim the Board has a formal schedule of matters specifically 
reserved to it for decisions including the approval of annual and interim 
results and recommendation of dividends, approval of annual budgets, 
approval of larger capital expenditure and investment proposals, review of 
the overall system of internal control and risk management and review of 
corporate governance arrangements. 

Other responsibilities are delegated to the Board Committees, being the 
Audit, Remuneration and Nomination committees, which as explained 
in section 5 above operate within clearly defined terms of reference, and 
which report back to the Board.

We have set out in section 2 above how we maintain a regular dialogue 
with our shareholders including welcoming all shareholders to our AGMs. 

Reports of the Board 
committees are also 
presented on pages  
32-33 in this Report.

meetings can be found

Corporate Governance Statement (continued)

Governance Report      30/31

The Board

The Board comprises the Chairman, two Executive Directors and two Non-Executive Directors. The Non-Executive 
Directors are considered to be independent, provide a solid foundation for good corporate governance for the Group, 
and ensure that no individual or group dominates the Board’s decision-making process. The Non-Executive Directors are 
independent of management. Each Non-Executive Director must continue to demonstrate that they have sufficient time to 
devote to the Company’s business and attendance at Board and Committee meetings is summarised later in this report.

The Non-Executive Directors constructively challenge and assist in developing the strategy of the Group using their 
experience and knowledge of acquisition targets and fundraising. They scrutinise the performance of management against 
the Group’s objectives and also monitor the reporting of performance. The Board is provided with regular and timely 
information on the financial performance of the Group as a whole, together with reports on trading matters, markets and 
other relevant matters.

There are clearly defined roles for the Chairman and CEO. The Chairman is responsible for leadership of the Board, 
ensuring effectiveness of the Board in all aspects, conducting Board meetings and the effective and timely communication 
of information to shareholders. The Chairman is able to provide advice, counsel and support to the Chief Executive. The 
Chief Executive has direct charge of the Group’s day-to-day activities and sets the operating plans and budgets required to 
deliver the agreed strategy. The Chief Executive is also responsible for ensuring that the Group has in place appropriate risk 
management and control mechanisms.

The Board is collectively responsible for the performance of the Group and is responsible to shareholders for proper 
management of the Group. A statement of Directors’ responsibilities is given on page 36 and a statement on going 
concern is given on pages 37-38.

The Board has a formal schedule of matters specifically reserved to it for decisions including the approval of annual and 
interim results and recommendation of dividends, approval of annual budgets, approval of larger capital expenditure 
and investment proposals, review of the overall system of internal control and risk management and review of corporate 
governance arrangements. Other responsibilities are delegated to the Board Committees, being the Audit, Remuneration 
and Nomination committees, which operate within clearly defined terms of reference, and which report back to the Board.

Relevant papers are distributed to members in advance of Board and Committee meetings. Directors’ knowledge and 
understanding of the Group is enhanced by visits to the operations and by receiving presentations by senior management 
on the results and strategies of the business units. Directors may take independent professional advice on any matter at 
the Company’s expense if they deem it necessary in order to carry out their responsibilities. The Company has secured 
appropriate insurance cover for Directors and Officers.

Board Committees

The following committees deal with specific aspects of the Group’s affairs.

Audit Committee
The Audit Committee, which is chaired by D. Tilston and has I. Napper as the other member, meets not less than twice 
annually and more frequently if required. 

The Board considers that both members of the Audit Committee have recent and relevant financial experience and 
an understanding of accounting and financial issues relevant to the industries in which SDI Group operates. The 
Committee provides a forum for reporting by the Group’s external auditors. Where appropriate meetings are also 
attended by the Chairman and executives at the invitation of the Committee.

nomination Committee
This Committee is chaired by Isabel Napper and has David Tilston as its other member and meets at least once per 
annum. Where appropriate meetings are also attended by the Chairman, the CEO and the CFO at the invitation of  
the Committee.

The Nomination Committee focuses on evaluating the Board of Directors, examining the skills and characteristics 
which are needed in Board candidates, and on succession issues. Its principal focus during the last financial year was 
in continuing to assist the Chairman with the Board evaluation process as set out in Principle 7 of our Governance 
Statement (page 28) and in leading the process of recruitment for the CFO following Jon Abell’s announcement of his 
intended retirement.

Attendance at Board and Committee Meetings

The members’ attendance at Board and Committee meetings during the year is disclosed in the table below. Ken Ford 
retired from the Remuneration Committee at the start of the year.

Conformance with Best Practice

The Board has reviewed its composition against certain non-statutory “best practice” guidelines and makes the  
following observations:

That remuneration of non-executive directors should be with basic fees only (excluding historical, one-off options 
grants if the quantum is not considered material)

–  The Group awarded one-time share option awards on appointment in 2017 and 2018 to its current non-executive 

directors, and these were considered at the time to be not material, although they became more valuable over time. 
These have since been exercised, and the Board does not expect to make further awards to non-executive directors. 
The Board therefore considers its non-executive directors to be independent of management and expects them to 
exercise their independence to the fullest extent.

That the remuneration committee should not include non-independent or executive members

–  Ken Ford has retired from the remuneration committee, and therefore all members are independent.

That the Company Secretary should not be an executive director

–  The Board members have significant external Board of Directors’ experience and are aware that they may seek 

independent professional advice at the company’s expense to discharge their duties. The Board believes that the 
company is currently best served by combining the roles of CFO and Company Secretary, in the interests of efficiency 
and cost. This will be reviewed on appointment of a new CFO in replacement of Jon Abell who is retiring.

A report of the Audit Committee is provided on page 32.

The Board expects to keep any such matters under at least annual review.

Remuneration Committee
A report of the Remuneration Committee and the Directors’ remuneration report can be found on pages 33-35.

Report of the Audit Committee

Report of the Remuneration Committee

     32/33

I am pleased to present the Audit 
Committee report for the year 
ended 30 April 2022. 

Composition of the 
Committee 

The Committee consists of myself 
(as Chairman) and Isabel Napper. 
The Chairman, Executive Directors 
and Group Financial Controller may 
be invited to attend Committee 
meetings if required. During the 
year, the Committee met four times, 
to approve the audit plan, review 
the audit conclusions and interim 
findings and to consider other 
matters delegated to the Committee. 
The Board is satisfied that I, as 
Chairman of the Committee, 
have recent and relevant financial 
experience. I am a Chartered 
Accountant; I have served as 
Group Finance Director in several 
quoted companies and have prior 
experience as an Audit Committee 
Chairman. I report the Committee’s 
activities at Board meetings and 
the minutes of each meeting are 
made available to all members 
of the Board. The Committee 
has satisfactorily completed a 
self-assessment exercise on its 
effectiveness using externally 
sourced material.

l  manage the relationship with 
the Group’s external Auditor 
and review their suitability and 
independence; 

l  negotiate and approve the external 
Auditor’s fee, the scope of their 
audit and terms of engagement; 

l  advise on the appointment of 

external Auditors and to review and 
monitor the extent of the non-
audit services undertaken by the 
Group’s external Auditor; 

l  review of the risk management and 

internal control systems; 

l  review the assessment of going 

concern; and 

l  assess the need for an internal 

audit function.

Role of the External Auditor 

The Committee monitors the 
relationship with its external Auditor, 
Grant Thornton UK LLP, to ensure 
that auditor independence and 
objectivity are maintained. As part 
of its review the Committee has 
established a policy in respect of 
the provision of non-audit services 
by the external Auditor which it 
monitors. No issues impacting 
upon the Auditor’s independence 
were observed or brought to the 
Committee’s attention.

Responsibilities 

Audit Process 

The Committee’s main duties are to: 

l  ensure the integrity of the financial 

statements (including annual 
and interim accounts and results 
announcements); 

l  review significant financial 

reporting judgements and the 
application of accounting policies 
thereon; 

l  ensure the Annual Report and 

Accounts are fair, balanced and 
understandable and recommend 
their approval to the Board;

The external Auditor prepares an 
audit plan for its review of the full 
year financial statements. The audit 
plan sets out the scope of the audit, 
specific areas of risk to target and the 
audit timetable. This plan is reviewed 
and agreed in advance by the 
Committee. Following completion of 
audit fieldwork the Auditor presented 
their findings to the Committee for 
discussion, including accounting 
judgements undertaken in respect of 
various matters including acquisition 
accounting and research and 
development capitalisation.

Internal Audit 

At present the Group does not have 
a formal internal audit function and 
the Committee will keep this matter 
under review as the Group’s  
activities expand.

Risk Management and 
Internal Controls 

The Corporate Governance 
Statement on pages 27-31 explains 
 the measures taken to embed 
effective risk management 
throughout the Group which is 
dependent upon the close 
involvement of the executive directors 
in the day-to-day operations of the 
Group, the strength of subsidiary 
management teams and reporting 
from the operating subsidiaries. The 
Group Financial Controller reports 
to the Committee on any internal 
controls’ weaknesses identified 
during his visits to subsidiaries. 
The Committee is responsible for 
reviewing the risk management 
and internal control framework and 
ensuring that it operates effectively. 
The Committee has reviewed the 
framework by (a) receiving papers 
and discussing oversight practices 
with the Group CEO, Group CFO and 
Group Financial Controller and (b) 
receiving a report from the external 
auditors on observations made during 
their audits of operating subsidiaries 
and determined that it remains 
appropriate for the Group’s current 
scale of operations.

David Tilston
Chairman 
Audit Committee  
21 July 2022

On behalf of the Board, I am 
pleased to present the report of the 
Remuneration Committee for the 
year ended 30 April 2022.

is simple and straightforward so 
that there is a clear link between 
Group performance and executive 
remuneration.

The Committee is chaired by myself 
and has David Tilston as its other 
member. Other regular attendees, 
at the invitation of the Committee, 
include the Chairman, the CEO and 
the CFO.

We meet as a Committee at least 
two times every year and our role 
is to determine the Group’s policy 
for executive remuneration and the 
individual remuneration packages 
for executive directors together 
with other designated senior 
management. A particular function 
of the Committee is the approval 
of all awards of share options to 
directors and staff. The Committee’s 
terms of reference are available on 
the Group’s website.

In setting the Group’s remuneration 
policy, the Committee considers 
a number of factors including the 
following: 

l  Salaries and benefits available 

to executive directors of 
comparable companies; 

l  The need to both attract and 

retain executives of appropriate 
calibre; and 

l  The continued commitment 
of executives to the Group’s 
profitable growth and sustainable 
development through 
appropriate incentive schemes 
(including the award of shares 
and share options). 

Remuneration of Executive 
Directors 

Consistent with this policy, the 
benefit packages awarded to our 
executive directors comprise a mix 
of basic salary and performance-
related remuneration aimed at 
incentivising executive behaviour 
to achieve the Group’s goals. We 
are keen to ensure that the package 

The remuneration packages cover 
the following elements: 

l  Base salary: the Remuneration 
Committee sets base salaries 
to reflect the responsibilities 
and the skills, knowledge and 
experience of the individual and 
the complexity of the role; 

l  Bonus Scheme: the executive 

directors are eligible to 
receive a bonus dependent 
on both individual and Group 
performance as determined by 
the Remuneration Committee. 
This has been capped at 50% of 
the individual’s salary; 

l  Long-Term Incentive Plan shares: 

the executive directors are 
eligible to receive share options, 
related to Group performance 
under the terms of a long-term 
incentive scheme determined by 
the Remuneration Committee; 

l  Equity: share options awarded as 

appropriate; and 

l  Group contribution into a 

personal pension scheme, life 
assurance, and private medical 
insurance. 

The CEO and CFO are engaged 
under separate contracts which 
require a notice period of six 
months given at any time by the 
Group or the individual. 

During the 2021-22 year, the 
Committee engaged remuneration 
consultants to benchmark the 
compensation of the executive 
directors, following several years 
of significant growth of the Group 
under current management and 
a period under the COVID-19 
pandemic during which the Group’s 
performance had been strong 
but compensation increases had 
been limited. It was decided to 

award salary increases in a phased 
approach, with an interim increase 
awarded in January 2022 and 
further adjustments expected in 
2022-23. The need to review in 
2022-23 the levels of all elements 
of the remuneration packages 
for the CEO and CFO has also 
been informed by the recruitment 
process for a replacement for  
Jon Abell as CFO.   

The details of the those awards 
already made under the LTIP 
scheme are set out in the 
Remuneration Report on  
pages 34-35.

Remuneration of Chairman 
and non-Executive Directors 

The fees paid to the non-executive 
directors are determined by the 
Board. The non-executive directors 
each received a single award of 
share options on appointment 
in 2017 and 2018, but these 
have since been exercised. The 
Chairman has participated until 
now in the Group’s LTIP scheme. 
The Chairman and non-executive 
directors do not receive any other 
forms of benefits such as medical 
insurance or pension. 

The Chairman and the non-
executive directors are engaged 
under service contracts each of 
which provide that notice of three 
months can be given at any time by 
the Group or the individual.

Long-Term Incentive Plan (“LTIP”)
This LTIP was introduced in December 2018 to provide an effective mechanism for senior executives to participate in 
the company’s equity, aligning their interests with those of the shareholders. The LTIP scheme overall has a duration of 
ten years and provides for a maximum of 10% of the company’s equity to be granted (under all schemes) to executives 
in that period, subject to performance conditions which are set for each award. Awards under the scheme in previous 
years have been made in December 2018 and in March 2020.

An award was made on 01 October 2021 with performance conditions based for 50% on the growth in fully-diluted 
Earnings Per Share in the three years starting 1 May 2021 and for 50% on the total shareholder return over three years 
for SDI shareholders compared with a basket of twenty comparable companies. Subject to the rules of the LTIP, vesting 
is on the third anniversary of the date of grant, to the extent that the performance conditions are met, with a minimum 
holding period of four years including the vesting period. 

The directors participating in the scheme at the date of this report and their maximum respective entitlements under the 
scheme to shares in SDI Group plc are as follows:

Directors’ Report 

Governance Report     36/37

Directors’ Responsibilities Statement

The directors are responsible for preparing the Annual Report comprising Strategic Report, Governance Report and 
the Financial Statements in accordance with applicable law and regulations.

Company law requires the directors to prepare financial statements for each financial year. Under that law the 
Directors have to prepare consolidated financial statements in accordance with applicable law and international 
accounting standards in conformity with the requirements of the UK-adopted international accounting standards 
and have elected to prepare separate parent company financial statements in accordance with United Kingdom 
Generally Accepted Accounting Practice (United Kingdom Accounting Standards and applicable laws, including 
FRS101 Reduced Disclosure Framework). Under company law the directors must not approve the financial statements 
unless they are satisfied that they give a true and fair view of the state of affairs of the Group and the Company and 
the profit or loss of the Company and the Group for that period. In preparing these financial statements, the directors 
are required to:

l  select suitable accounting policies and then apply them consistently

l  make judgements and accounting estimates that are reasonable and prudent

l  state whether applicable international accounting standards in conformity with the requirements of the UK-

adopted international accounting standards have been followed, subject to any material departures disclosed and 
explained in the Group and parent company financial statements respectively

l  prepare the financial statements on the going concern basis unless it is inappropriate to presume that the 

Company or the Group will continue in business.

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the 
Group’s transactions and disclose with reasonable accuracy at any time the financial position of the Group and enable 
them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for 
safeguarding the assets of the Group and hence for taking reasonable steps for the prevention and detection of fraud 
and other irregularities.

The directors confirm that:

Directors

The directors who served during the year are set out below. 

K Ford  |  M Creedon  |  I Napper  |  D Tilston  |  J Abell

The interests of the directors and their families in the share capital of the Company are shown in the directors’ 
remuneration report on page 34-35.

The appointment and replacement of directors of the Company is governed by its Articles of Association and the 
Companies Act 2006. The Articles of Association may be amended by special resolution of the shareholders.

The Company must have a minimum of two directors holding office at all times. There is no maximum number of directors. 
The Company may by ordinary resolution, appoint any person to be a director. The Board may appoint a person who is 
willing to act as director, either to fill a vacancy or as an addition to the Board. A director appointed in this way may hold 
office only until the dissolution of the next Annual General Meeting unless he or she is reappointed during the meeting.

Directors’ Indemnities

The directors have the benefit of an indemnity from the Company in respect of liabilities incurred as a result of their 
office. This indemnity is provided under the Company’s Articles of Association and satisfies the indemnity provisions of 
the Companies Act 2006. The Company has taken out an insurance policy in respect of those liabilities for which the 
directors may not be indemnified. Neither the indemnity nor the insurance provides cover in the event that a director is 
proved to have acted dishonestly or fraudulently.

Power Of Directors

The directors are responsible for the management of the business of the Company and may exercise all powers of the 
Company subject to applicable legislation and regulation and the Memorandum and Articles of Association.

At the Annual General Meeting held on 21 September 2021, the directors were given the power to:

l  Allot ordinary shares up to an aggregate nominal value of £330,000;

l  Issue equity securities for cash, otherwise than to existing shareholders in proportion to their existing 

l  so far as each director is aware there is no relevant audit information of which the Group’s auditor is unaware; and

shareholdings, up to an aggregate nominal value of £49,500.

l  the directors have taken all steps that they ought to have taken as directors in order to make themselves aware of 

any relevant audit information and to establish that the Group’s auditor is aware of that information.

The directors are responsible for the maintenance and integrity of the corporate and financial information included 
on the Group’s website. Legislation in the United Kingdom governing the preparation and dissemination of financial 
statements may differ from legislation in other jurisdictions. 

Group Results 

The Group’s profit for the year after taxation amounted to £7.5m (2021: £4.7m) and has been transferred to reserves.

All KPIs and risks are disclosed in the Strategic Report on pages 20 and 25. 

The Board does not recommend the payment of a dividend. 

Similar powers will form part of the resolutions to be put to the forthcoming AGM expected to be held on  
21 September 2022.

Going Concern

The consolidated financial statements have been prepared on a going concern basis. The Group’s business activities, 
together with the factors likely to affect its future development, performance and position are set out within this 
Strategic report. The financial position of the Group, its cash flows, and liquidity position are provided in the financial 
statements on pages 54-57.

The Group ended 2022 with net cash of £1.1m compared to £0.7m at 30 April 2021 and generated cash from operations 
of £14.7m. This cash generation arose from the strong performance of the Group’s principal operating companies, 
enabled by 21.6% organic growth, and was mostly deployed in acquiring profitable businesses. In addition, the Group 
also increased its borrowing facilities on 01 November 2021 to £20m and extended the repayment date to November 
2024, providing the Group with greater certainty over long-term liquidity. An amount totalling £4m is currently drawn 
down under this facility (see note 20).

Going Concern (continued)

Substantial Shareholdings

The Board have considered the ongoing impacts of the Covid-19 pandemic and the war in Ukraine, including their 
effects on the wider economy. The Group is in a strong financial position with high cash balances and available 
facilities, sufficient headroom on all covenants associated with the debt, good profitability and a strong future  
order book, enabling it to face any reasonable likely challenge of the continued uncertain global economic 
environment. The Board has reviewed forecasts for the period to 31 October 2024, including severe downside 
scenarios which the Board considers extremely unlikely and would not cause any significant challenges to the 
Group’s continued existence. 

The Board therefore have a reasonable expectation that the Group has adequate resources to continue in  
operational existence for the foreseeable future and therefore continue to adopt the going concern basis in  
preparing the Annual Report and Accounts.

Post Balance Sheet Events

There are no events to note.

Research and Development

Each of the Group’s businesses devotes appropriate resources to maintaining and expanding its competitive position 
by researching and developing new products and processes as well as updating existing products. 51 employees  
were employed for development activities in the year (2021: 42).

Future Development

The directors expect that the Group will continue to execute its strategy of acquiring and managing niche  
technology businesses.

Structure of Share Capital

As at 30 April 2022 the Company’s authorised share capital was £10,000,000 comprising 1,000,000,000 ordinary 
shares of 1p each. As at 30 April 2022 the Company had 102,199,676 (2021: 98,408,164) ordinary shares in issue  
with a nominal value of 1p each.

Corporate Governance

Corporate Governance is discussed on pages 27-31. 

Financial Risk Management Objectives and Policies

Financial risk management objectives and policies are discussed in note 26.

Employee Engagement with other Stakeholders

The company engages with its employees and other stakeholders as disclosed in the Section 172(1) statement on 
pages 22-23.

Health and Safety Policies

The Group is committed to conducting its business in a manner which ensures high standards of health and safety  
for its employees, visitors and general public. It complies with all applicable and regulatory requirements.

Streamlined Energy and Carbon Reporting (“SECR”)

The Group does not report under SECR as none of its subsidiary undertakings are large companies. The parent 
company is exempt from reporting as it is a low energy user consuming less than 40MWh per annum.

As of 21 July 2022 the Company is aware of the following shareholders who hold an interest of 3% or more in the 
Company’s ordinary share capital.

Report of the Independent Auditor
to the members of the SDI Group plc

 Financial Statements     40/41

Opinion

Our opinion on the financial statements is unmodified

We have audited the financial statements of SDI Group plc (the ‘parent company’) and its subsidiaries (the 
‘Group’) for the year ended 30 April 2022, which comprise the Consolidated Income Statement & Statement 
of Comprehensive Income, the Consolidated Balance Sheet, the Consolidated Statement of Cash Flows, 
the Consolidated Statement of Changes in Equity, the notes to the Consolidated Financial Statements 
including a summary of significant accounting policies, the Company Balance Sheet, the Company Statement 
of Changes in Equity, and the notes to the Company Financial Statements including a summary of significant 
accounting policies. The financial reporting framework that has been applied in the preparation of the Group 
financial statements is applicable law and UK-adopted international accounting standards. The financial reporting 
framework that has been applied in the preparation of the parent company financial statements is applicable 
law and United Kingdom Accounting Standards, including Financial Reporting Standard 101 ‘Reduced Disclosure 
Framework’ (United Kingdom Generally Accepted Accounting Practice).

In our opinion:

  l  the financial statements give a true and fair view of the state of the Group’s and of the parent company’s  

  affairs as at 30 April 2022 and of the Group’s profit for the year then ended;

  l  the Group financial statements have been properly prepared in accordance with UK-adopted international  

  accounting standards;

  l  the parent company financial statements have been properly prepared in accordance with United Kingdom  

  Generally Accepted Accounting Practice; and

  l  the financial statements have been prepared in accordance with the requirements of the Companies 

  Act 2006.

Basis for Opinion

We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law.  
Our responsibilities under those standards are further described in the ‘Auditor’s responsibilities for the audit of the 
financial statements’ section of our report. We are independent of the Group and the parent company in accordance  
with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC’s 
Ethical Standard as applied to listed entities, and we have fulfilled our other ethical responsibilities in accordance with 
these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a  
basis for our opinion.

Conclusions Relating to Going Concern 

We are responsible for concluding on the appropriateness of the directors’ use of the going concern basis of accounting 
and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may 
cast significant doubt on the Group’s and the parent company’s ability to continue as a going concern. If we conclude 
that a material uncertainty exists, we are required to draw attention in our report to the related disclosures in the financial 
statements or, if such disclosures are inadequate, to modify the auditor’s opinion. Our conclusions are based on the audit 
evidence obtained up to the date of our report. However, future events or conditions may cause the Group or the parent 
company to cease to continue as a going concern.

Extent of Management Judgement

High

Our evaluation of the directors’ assessment of the 
Group’s and the parent company’s ability to continue to 
adopt the going concern basis of accounting included: 

l  obtaining management’s base case forecasts 

covering the period to 31 October 2024, assessing 
how these forecasts were compiled and assessing 
their appropriateness by applying sensitivities to the 
underlying assumptions, which we also challenged; 

l  assessing the accuracy of management’s forecasting 
by comparing the reliability of past forecasts to past 
actual results;

l  obtaining management’s downside scenarios prepared 

to assess possible risks to going concern, and 
management’s mitigating actions; and 

l  assessing the adequacy of related disclosures within 

High

the Annual Report 2022.

In our evaluation of the directors’ conclusions, we

considered the inherent risks associated with the Group’s 
Statement

and the parent company’s business model including effects 

arising from macro-economic uncertainties such as the 
Ukraine crisis and Covid-19, we assessed and challenged the 
reasonableness of estimates made by the directors and the 
related disclosures and analysed how those risks might affect 
the Group’s and the parent company’s financial resources or 
ability to continue operations over the going concern period.

Based on the work we have performed, we have not 
identified any material uncertainties relating to events 
or conditions that, individually or collectively, may cast 
significant doubt on the Group’s and the parent company’s 
ability to continue as a going concern for a period of at 
least twelve months from when the financial statements are 
authorised for issue.

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 Results/
Key Observations

Our auditor’s report for the year ended 30 April 2021 included one key 
audit matter that has not been reported a key audit matter in our current 
year’s report. This relates to going concern, which has no longer been 
assessed as a significant risk.

We performed an audit of the financial information using component materiality (full-scope audit) for the parent 
company, SDI Group plc, and four other significant components of the Group. This gave coverage of 74% of the 
Group’s total assets, 54% of the Group’s revenue and 73% of the Group’s profit before tax.

Materiality

We performed an audit of one or more account balances, classes of transactions or disclosures of the component 
(specific-scope audit) for the eight non-significant UK Group components. This gave additional coverage of 23% of  
the Group’s total assets, 40% of the Group’s revenue and 25% of the Group’s profit before tax.

Analytical procedures were performed for all other components of the Group that were neither significant nor material. 

There were no changes to the audit approach from the prior year.

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

Improper Revenue Recognition

We identified improper revenue recognition as one 
of the most significant assessed risks of material 
misstatement due to fraud. 

There is an underlying incentive for performance to 
be inflated through inaccurate revenue recognition. 
This risk is therefore judged to be due to fraud.

The Group has recognised revenue of £50m (2021: 
£35m) in its consolidated income statement during 
the year, which is comprised of revenue from sales 
of goods and income from service contracts.

As the Group’s revenue comprises various 
individually material streams which are either 
recognised at a point in time or over time in 
accordance with IFRS 15 ‘Revenue from Contracts 
with Customers’, the risk that revenue may be 
improperly recognised has been identified as a 
significant risk. This significant risk was pinpointed to 
transactions that did not follow the normal business 
process for certain subsidiaries, or for a single 
contract which was highly material in relation to one 
subsidiary, or for service contracts the significant risk 
was pinpointed to the last quarter of the year where 
the risk of incomplete deferred income was greatest.

In responding to the key audit matter, we performed 
the following audit procedures: 
l obtained an understanding of the process followed 
for the recognition of revenue and tested the design 
and implementation of relevant controls. From the 
work performed, we noted two significant control 
deficiencies in relation to service revenue at the 
component Monmouth Scientific Limited, and as a 
result, we extended our detailed testing in this area 
to address the increased level of risk;

l  assessed whether the revenue recognition 

accounting policy for each type of revenue  
was consistent with IFRS 15 and testing that  
these policies were followed through our 
substantive tests;

l  performed data analytics procedures designed 

to highlight any unusual transactions or postings 
recorded in revenue, which were then all subject  
to detailed testing;

l  tested a sample of revenue transactions in respect 
of sale of goods and agreeing them to a cash 
receipt or proof of delivery to check that the sale  
did occur;

l  tested a sample of revenue transactions in respect 

of contract income for services by obtaining 
supporting documentation to prove occurrence, 
recalculating the revenue recognised, and assessing 
the appropriateness of any deferred or accrued 
income at year end; and

l  agreed a sample of transactions before and after the 
year end to supporting documentation to determine 
whether transactions had been recorded in the 
correct period.

Valuation of Intangible Assets on 
Recognition of Acquired Businesses

We identified the valuation of intangible assets 
on recognition of acquired businesses as one 
of the most significant assessed risks of material 
misstatement due to error.

There is a risk that the intangible assets, including 
goodwill, are not recognised in accordance with 
IFRS 3 ‘Business Combinations’.

Specifically, there is significant judgement and 
complexity associated with the allocation of excess 
consideration over net assets acquired between 
separable intangible assets and remaining goodwill. 

Due to the inherent uncertainty and key 
assumptions involved in management’s calculation 
of the valuation of acquired intangible assets, we 
determined the risk to be a significant risk.

In responding to the key audit matter, we  
performed the following audit procedures:

 l assessed the Group’s accounting for 

acquisitions to check whether it was in  
accordance with the Group’s financial reporting 
framework, including IFRS 3;

l  assessed the consideration for the acquisitions, 

including work around any deferred or  
contingent consideration;

l  used our auditor’s expert to assess the 

appropriateness of the valuation methodology 
used by management, including the methodology 
adopted for identifying separate intangible 
assets distinct from goodwill and assessing the 
appropriateness of discount rates and growth  
rates applied;

l  evaluated the acquisition workings prepared by 
management and checking its mathematical 
accuracy; and

l  challenged the assumptions used in the valuation 
models, to assess whether they are reasonable  
and consistent with our knowledge of the  
acquired businesses.

Impairment of intangible assets in 
relation to the Monmouth CGu

In responding to the key audit matter, we performed 
the following audit procedures:

We identified the risk of impairment in relation to 
the Monmouth CGU as one of the most significant 
assessed risks of material misstatement due to error.

 l obtained an understanding of the process followed 

for the impairment assessment and tested the 
design and implementation of relevant controls; 

This is due to the Monmouth CGU having the lowest 
headroom and the level of management judgement 
and assumptions required to perform the annual 
impairment test required under IAS 36 ‘Impairment 
of Assets’. As a result, there is a risk that the carrying 
value of the CGU may exceed its recoverable 
amount and therefore be subject to impairment.

Relevant Disclosures in the Annual 
Report 2022

l  Financial statements: 

Note 10, Intangible Assets. 

l  obtained management’s model to identify the key 
assumptions and assess the arithmetical accuracy 
of the model. The assumptions identified have been 
challenged and corroborated by the audit team 
to ensure they are reasonable and in line with the 
requirements of IAS 36; 

l  used an auditor’s expert to recalculate a range 

for the discount rate applied and to confirm the 
reasonableness of key inputs and assumptions used 
in management’s model, which led to a change in 
management’s base case model; 

l  assessed the impairment review prepared by 

management, mainly through the use of applying 
sensitivities; and

l  performed sensitivity analyses on the key assumptions 

and inputs into the value in use calculations.

Key Observations

Based on our audit work, there is no material 
impairment of the Monmouth CGU, but there are 
reasonably possible changes in assumptions which 
could cause an impairment. These have been 
appropriately disclosed by management in the 
financial statements.

We did not identify any key audit matters relating to the audit of the parent company.

Our Application of Materiality

We apply the concept of materiality both in planning and performing the audit, and in evaluating the effect of identified 
misstatements on the audit and of uncorrected misstatements, if any, on the financial statements and in forming the 
opinion in the auditor’s report.

Materiality was determined as follows:

Materiality Measure Group

Parent Company

Materiality for 
financial statements 
as a whole

We define materiality as the magnitude of misstatement in the financial statements that, 
individually or in the aggregate, could reasonably be expected to influence the economic 
decisions of the users of these financial statements. We use materiality in determining the 
nature, timing and extent of our audit work.

Materiality  
threshold

£503,000, which is 5% of the Group’s profit 
before tax at the planning stage of the audit. 

£377,000, which is 2% of the parent company’s 
total assets at the planning stage of the audit, 
capped due to the aggregate of the Group’s 
significant component materialities exceeding 
the firm’s permitted multiple.

Significant 
judgements 
made by auditor 
in determining 
materiality

In determining materiality, we made the 
following significant judgements:

In determining materiality, we made the 
following significant judgements: 

l  Profit before tax is considered the most 

appropriate benchmark because the Group 
is a commercially focused organisation and 
profit before tax is a key financial measure 
for the directors and the shareholders.

l  We used a measurement percentage of 5% 
as the Group’s profit before tax is relatively 
stable and therefore we have used the top 
of the firm’s permissible range.

Materiality for the current year is higher than 
the level that we determined for the year 
ended 30 April 2021 to reflect the improved 
trading performance this year.

l  An asset-based benchmark was 
considered the most appropriate 
benchmark because the parent company 
is a holding company. This was changed 
from 10% of profit before tax in the prior 
year because total assets is a more  
relevant benchmark for a parent company 
that does not trade in its own right.

l  We used a measurement percentage of 2% 
as the parent company’s total assets are 
relatively stable and therefore we have used 
the top of the firm’s permissible range.

Materiality for the current year is higher than 
for the year ended 30 April 2021 to reflect 
the change in benchmark and measurement 
percentage from 10% of the parent company’s 
profit before tax last year, as noted above.

Performance 
materiality used to 
drive the extent of 
our testing

We set performance materiality at an amount less than materiality for the financial 
statements as a whole to reduce to an appropriately low level the probability that the 
aggregate of uncorrected and undetected misstatements exceeds materiality for the  
financial statements as a whole.

Performance 
materiality  
threshold

£377,000, which is 75% of financial  
statement materiality.

£283,000, which is 75% of financial 
statement materiality.

We performed a risk-based audit that requires an understanding of the Group’s and the parent company’s business and 
in particular matters related to:

understanding the group, its components, and their environments, including group-wide controls

l  the engagement team obtained an understanding of the Group and its environment, including Group-wide controls, 

and assessed the risks of material misstatement at the Group level;

l  the engagement team obtained an understanding of the Group’s organisational structure and considered its effect 

on the scope of the audit, identifying that the Group financial reporting system is centralised;

Identifying significant components 

l  Significant components were identified through assessing their relative share of key financial metrics including 

revenue, profit before tax, fixed assets, current assets and current liabilities.

Type of work to be performed on financial information of parent and other components (including how it addressed 
the key audit matters)

l  We identified five significant components within the Group and performed a full scope audit on the financial 

information of each. Our work on these significant components included the areas of focus identified as key audit 
matters above.

l  We performed an audit of one or more account balances, classes of transactions or disclosures of the component 

(specific-scope audit) for the eight non-significant UK Group components. 

l  Analytical procedures were performed for insignificant components.

Other Information

The directors are responsible for the other information. The other information comprises the information included 
in the Annual Report 2022, 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. 

In connection with our audit of the financial statements, our responsibility is to read the other information and, 
in doing so, consider whether the other information is materially inconsistent with the financial statements or 
our knowledge obtained in the audit or otherwise appears to be materially misstated. If we identify such material 
inconsistencies or apparent material misstatements, we are required to determine whether there is a material 
misstatement of the financial statements or a material misstatement of the other information. If, based on the work 
we have performed, we conclude that there is a material misstatement of this other information, we are required to 
report that fact. 

We have nothing to report in this regard.

Our opinion on other matters prescribed by the Companies Act 2006 is unmodified

In our opinion, based on the work undertaken in the course of the audit:

  l  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

  l  the strategic report and the directors’ report have been prepared in accordance with applicable 

legal requirements.

Matter on which we are required to report under the Companies Act 2006
In the light of the knowledge and understanding of the Group and the parent company and 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:

l  a 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

l  the parent company financial statements are not in agreement with the accounting records and returns; or

l  certain disclosures of directors’ remuneration specified by law are not made; or

l  we have not received all the information and explanations we require for our audit.

Responsibilities of directors for the financial statements
As explained more fully in the directors’ responsibilities statement, 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.

A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting 
Council’s website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor’s report.

Explanation as to what extent the audit was considered 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. 
Owing to the inherent limitations of an audit, there is an unavoidable risk that material misstatements in the financial 
statements may not be detected, even though the audit is properly planned and performed in accordance with ISAs (UK). 

The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below: 

l  We obtained an understanding of the legal and regulatory frameworks that are most applicable to the Group and 

the parent company and determined the most significant are those that relate to the financial reporting framework, 
being the Companies Act 2006 and UK-adopted international accounting standards for the Group, and the 
Companies Act 2006 and FRS 101 ‘Reduced disclosure framework’ for the parent company, together with relevant 
tax compliance regulations. In addition, we concluded that there are certain other significant laws and regulations 
that may have an effect on the determination of the amounts and disclosures in the financial statements, being laws 
and regulations relating to health and safety, employee matters, and bribery and corruption practises. 

l  We obtained an understanding of how the Group and the parent company are complying with legal and regulatory 
frameworks by making enquiries of management, those responsible for legal and compliance procedures and the 
company secretary. We corroborated our enquiries through our review of Board minutes and papers provided to the 
Audit Committee.

l  We enquired of management and the Audit Committee about the Group’s policies and procedures relating to the 
identification, evaluation and compliance with laws and regulations and the detection and responsible to the risks  
of fraud and the establishment of internal controls to mitigate risks related to fraud or non-compliance with laws  
and regulations.

l  We assessed the susceptibility of the Group’s financial statements to material misstatement, including how fraud 

might occur, by evaluating management’s incentives and opportunities for manipulation of the financial statements. 
This included the evaluation of the risk of management override of controls. We determined that the principal risks 
were in relation to areas of increased management judgement, specifically share-based payments, acquisition 
accounting and the impairment of intangible assets, all of which could be impacted by management bias, as well as 
the risk of fraud through the use of journal entries that increase revenues.

l  Audit procedures performed by the engagement team included: 

–  Identifying and assessing the design and implementation of controls management has in place to prevent and 
  detect fraud;

–  Obtaining an understanding of how those charged with governance considered and addressed the potential for  
  management override of controls or other inappropriate influence over the financial reporting process; 

–  Identifying and testing journal entries, in particular any journal entries posted with unusual account 
  combinations; and 

–  Challenging assumptions and judgements made by management in its significant accounting estimates. 

l  These audit procedures were designed to provide reasonable assurance that the financial statements were free 
from fraud or error. The risk of not detecting a material misstatement due to fraud is higher than the risk of not 
detecting one resulting from error and detecting irregularities that result from fraud is inherently more difficult than 
detecting those that result from error, as fraud may involve collusion, deliberate concealment, forgery or intentional 
misrepresentations. Also, the further removed non-compliance with laws and regulations is from events and 
transactions reflected in the financial statements, the less likely we would become aware of it.

Reporting Entity

SDI Group plc, a public limited company, is the Group’s ultimate parent. It is registered and 
domiciled in England and Wales. The consolidated financial statements of the Group for the  
year ended 30 April 2022 comprise the Company and its subsidiaries (together referred to  
as the “Group”). The details of subsidiary undertakings are listed in note 4 to the Company  
Financial Statements.

Basis of Preparation

The consolidated financial statements have been prepared and approved by the directors in 
accordance with International accounting standards in conformity with the requirements of  
the Companies Act 2006. The consolidated financial statements have been prepared under the 
historical cost convention as modified by the recognition of certain financial instruments at  
fair value.

The principal accounting policies of the Group are set out below. 

The consolidated financial statements are presented in British pounds (£), which is also the 
functional currency of the ultimate parent company. All values are rounded to the nearest 
thousand (£’000) except where otherwise indicated.

Going concern
The consolidated financial statements have been prepared on a going concern basis. The Group’s 
business activities, together with the factors likely to affect its future development, performance 
and position are set out within this Strategic report. The financial position of the Group, its cash 
flows, and liquidity position are provided in the financial statements on pages 54-57.

The Group ended 2022 with net cash of £1.1m compared to £0.7m at 30 April 2021 and generated 
cash from Operations of £14.7m. This cash generation arose from the strong performance of the 
Group’s principal operating companies, enabled by 21.6% organic growth, and was mostly 
deployed in acquiring profitable businesses. In addition, the Group also refinanced its borrowing 
facilities on 01 November 2021, extending the loan facility to £20m and the repayment date to 
November 2024, providing the Group with greater certainty over long-term liquidity. An amount 
totalling £4m is currently drawn down under this facility (see note 20).

The Board have considered the ongoing impacts of the Covid-19 pandemic and the war in Ukraine, 
including their effects on the wider economy. The Group is in a strong financial position with high 
cash balances and available facilities, sufficient headroom on all covenants associated with the 
debt, good profitability and a strong future order book, enabling it to face any reasonable likely 
challenge of the continued uncertain global economic environment. The Board has reviewed 
forecasts for the period to 31 October 2024, including severe downside scenarios which the Board 
considers extremely unlikely and would not cause any significant challenges to the Group’s 
continued existence. 

The Board therefore have a reasonable expectation that the Group has adequate resources to 
continue in operational existence for the foreseeable future and therefore continue to adopt the 
going concern basis in preparing the Annual Report and Accounts.

Changes in accounting policies
At the date of approval of these financial statements, certain new standards, amendments to and 
interpretations of existing standards have been published but are not yet effective. None of these 
pronouncements have been adopted early by the Group, and they have not been disclosed as they 
are not expected to have a material impact on the Group’s financial statements. Management 
anticipates that all pronouncements will be adopted for the first period beginning on or after their 
effective date.

Accounting judgements and estimates
The preparation of financial statements requires management to make judgements, estimates and 
assumptions that affect the application of policies and reported amounts of assets, liabilities, 
income and expenses. These judgements and estimates are based on management’s best 
knowledge of the relevant facts and circumstances, having regard to prior experience, but actual 
results may differ from the amounts included in the consolidated financial statements. 

Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting 
estimates are recognised in the period in which the estimate is revised and in any future periods 
affected. Information about significant areas of estimation uncertainty and critical judgements in 
applying accounting policies that have the most significant effect on the amount recognised in the 
financial statements are described in the following notes:

Judgements in applying accounting policies
Intangibles – development costs
The Group is required to capitalise any development costs that meet the criteria as per IAS 38.  
(See Research and Development accounting policy, page 61 and in note 10). The point at which 
development costs meet the criteria for capitalisation is critically dependent on management’s 
judgement of the point at which technical feasibility is demonstrable. The carrying value of 
development assets also depends on management’s ability to demonstrate the future economic 
benefits they will deliver. This judgement requires assumptions about factors outside the business’s 
control such as medium-term economic conditions, technological developments and market 
changes. The Group tests annually whether the capitalised development costs have been impaired 
by reference to expected future generation of cash from the technologies developed and the 
timing of when these will be released. 

Sources of estimation uncertainty
Fair value assessments of business combinations 
Following an acquisition, management makes an assessment of the fair value of all assets and 
liabilities acquired, including intangible assets and goodwill. The valuation process requires a 
number of estimates to be made, including an estimate of any earnout cash payment which is 
contingent on specific performance targets being met. For details of assumptions, see note 29.

Carrying value of goodwill and other intangible assets
The impairment analysis of intangible assets is based upon future discounted cash flows and a 
number of assumptions are made to estimate the future cash flows expected to arise from the cash 
generating unit as well as a suitable discount rate in order to calculate present value. Factors like 
lower than anticipated sales and resulting decreases of net cash flows and changes in discount 
rates could lead to impairment. For details of assumptions see note 10.

Principal Accounting Policies 

The principal accounting policies adopted are consistent with those of the annual financial 
statements for the year ended 30 April 2021. 

Basis of consolidation
Subsidiaries are entities controlled by the Group where control is the power to govern the financial 
and operating policies of an entity so as to obtain benefits from its activities. The financial 
statements of subsidiaries are included in the consolidated financial statements from the date that 
control commences until the date that control ceases. The subsidiaries financial statements have 
been prepared in accordance with FRS 101.

Intra group balances and any unrealised income and expenses arising from intra group transactions 
are eliminated in preparing the consolidated financial statements.

Business combinations
Business combinations are accounted for using the acquisition method under the revised  
IFRS 3 Business combinations. The consideration transferred by the Group to obtain control of a 
subsidiary is calculated as the sum of the acquisition-date fair value of assets transferred, liabilities 
incurred, and the equity interests issued by the Group, which includes the fair value of any asset or 
liability arising from a contingent consideration agreement. Acquisition costs are expensed within 
administration expenses as incurred. The Group recognises identifiable assets acquired and 
liabilities assumed including contingent liabilities in a business combination regardless of whether 
they have been previously recognised in the acquiree’s financial statements prior to the acquisition. 
Assets acquired and liabilities assumed are generally measured at their acquisition-date fair values. 

Foreign currency
Transactions entered into by Group entities in a currency other than the functional currency  
of the company which incurred them are recorded at the rate of exchange at the time of the 
transaction. Monetary assets and liabilities denominated in foreign currencies at the balance sheet 
date are reported at the rates of exchange prevailing at that date. Exchange differences arising on 
the retranslation of unsettled monetary assets and liabilities are recognised immediately in the 
income statement.

For the purpose of presenting the consolidated financial statements the assets and liabilities of  
the Group’s overseas operations are translated using exchange rates prevailing on the balance 
sheet date. Exchange differences on net assets arising from this policy are recognised in other 
comprehensive income and accumulated in the foreign exchange reserve; such translation 
differences are reclassified from equity to profit or loss as a reclassification adjustment in the  
period in which the foreign operation is disposed of.

Income and expense items of overseas operations are translated at exchange rates approximating 
to those ruling when the transactions took place. 

Property, plant and equipment
Property, plant and equipment is stated at cost, less accumulated depreciation. Depreciation is 
charged to the income statement on a straight-line basis over the estimated useful lives of each 
part of property, plant and equipment to write down the cost of the asset to its residual value. 

The estimated useful lives are as follows:

Motor vehicles
Computer equipment
Tools and other equipment
Furniture, fixtures and fittings
Building and leasehold improvements

3 years
3 years 
3 years 
5 years 
Over the lease term 

Goodwill
Goodwill represents the excess of the fair value of the consideration transferred over the Group’s 
interest in the net fair value of the identifiable assets, liabilities and contingent liabilities of the 
acquiree. When the excess is negative, it is recognised immediately in the income statement as a 
gain from a bargain purchase. Goodwill is reviewed for impairment annually or more frequently if 
events or changes in circumstances indicate that the carrying value may be impaired. Goodwill is 
also reviewed for impairment immediately following an acquisition. The impairment of goodwill is 
based upon value in use, determined using estimated future discounted cash flows.

Research and development
Expenditure on research activities undertaken with the prospect of gaining new scientific or 
technical knowledge and understanding is recognised in the income statement as an expense  
as incurred.

Expenditure on development activities, whereby research findings are applied to a plan or design 
for the production of new or substantially improved products and processes, is capitalised if the 
following conditions are met:

l  Completion of the intangible asset is technically feasible so that it will be available for use or sale;

l  The Group intends to complete the intangible assets and use or sell it;

l  The Group has the ability to use or sell the intangible asset;

l  The intangible asset will generate probable future economic benefits. Among other things, 

this requires that there is a market for the output from the intangible asset or the intangible asset 
itself, or, if it is to be used internally, the asset will be used for generating such benefits; and

l  The expenditure attributable to the intangible asset during its development can be 

measured reliably.

The expenditure capitalised includes direct cost of material, direct labour and an appropriate 
proportion of overheads. Other development expenditure is recognised in the income statement 
as an expense as incurred. Capitalised development is stated at cost less accumulated amortisation 
and impairment losses.

Amortisation is charged to the income statement on a straight-line basis over the estimated useful 
lives of intangible assets. Amortisation is shown within administrative expenses in the income 
statement. The estimated useful lives of current development projects are three years. Until 
completion of the project the assets are subject to impairment testing.

Other intangible assets
Intangible assets acquired as part of an acquisition of a business are capitalised separately from 
goodwill providing the assets are separable or they arise from contractual or other legal rights and 
their fair value can be measured reliably. The fair value of intangible assets in a business 
combination includes the value of any tax benefit.

Intangible assets with a finite life are amortised over their useful economic lives. Amortisation is 
recognised in the income statement within administrative expenses on a straight-line basis over the 
estimated useful lives of intangible assets, other than goodwill, from the date that they are available 
for use.

Principal Accounting Policies (continued) 

Impairment
The carrying amounts of the Group’s non-financial assets, other than inventories and deferred tax 
assets, are reviewed at each reporting date to determine whether there is any indication of 
impairment. If any such indication exists, then the asset’s recoverable amount is estimated. For 
intangible assets that have indefinite lives or that are not yet available for use, the recoverable 
amount is estimated at each reporting date.

The recoverable amount of an asset is the greater of its value in use and its fair value less costs to 
sell. In assessing value in use, the estimated future cash flows are discounted to their present value 
using a pre-tax discount rate that reflects current market assessments of the time value of money 
and the risks specific to the asset.

For the purpose of assessing impairment, assets are grouped at the lowest levels for which there 
are largely independent cash flows (cash-generating units). As a result, some assets are tested 
individually for impairment, and some are tested at cash-generating unit level. 

Goodwill is allocated to those cash-generating units or groups of cash-generating units that are 
expected to benefit from synergies of the related business combination, typically the Group’s 
operating segments, which represent the lowest level within the Group at which management 
monitors goodwill. 

An impairment loss is recognised if the carrying amount of an asset exceeds its recoverable 
amount. Impairment losses are recognised in the income statement. Impairment losses for cash-
generating units reduce first the carrying value of any goodwill allocated to that cash generating 
unit. Any remaining impairment loss is charged pro rata to the other assets in the cash-generating 
unit. With the exception of goodwill, all assets are subsequently reassessed for indicators that an 
impairment loss previously recognised may no longer exist.

Any impairment in respect of goodwill is not reversed. Impairment losses on other assets 
recognised in prior periods are assessed at each reporting date for any indications that the loss has 
decreased or no longer exists. An impairment loss is reversed if there has been a change in the 
estimates used to determine the recoverable amount. An impairment loss is reversed only to the 
extent that the asset’s carrying amount does not exceed the carrying amount that would have been 
determined, net of depreciation or amortisation, if no impairment had been recognised.

Inventories
Inventories are measured at the lower of cost and net realisable value. The cost of inventories 
comprises all costs of purchase, costs of conversion and other costs incurred in bringing the 
inventories to their location and condition at the balance sheet date. Items are valued using the first 
in, first out method. When inventories are used, the carrying amount of these inventories is 
recognised as an expense in the period in which the related revenue is recognised. Provisions for 
write-down to net realisable value and losses of inventories are recognised as an expense in the 
period in which the write-down or loss occurs.

Cash and cash equivalents
Cash and cash equivalents comprise cash balances and deposits which are subject to an 
insignificant risk of changes in value.

Borrowings
Borrowings are recognised initially at fair value, net of transaction costs incurred. Borrowings are 
subsequently stated at amortised cost. Any difference between the proceeds and the redemption 
value is recognised in the income statement over the period of the borrowings using the effective 
interest method. Borrowings are classified as current liabilities unless the Group has an 
unconditional right to defer settlement of the liabilities for at least 12 months after the balance 
sheet date. 

Equity
Equity comprises the following:

l  “Share capital” represents the nominal value of equity shares

l  “Merger reserve” represents the difference between the parent company’s cost of investment 

and the subsidiary’s share capital and share premium where a group reorganisation qualifies as a 
common control transaction.

l  “Share premium account” represents the excess over nominal value of the fair value of 

consideration received for equity shares, net of expenses of the share issue.

l  “Share-based payment reserve” represents equity-settled share-based employee remuneration 

until such share options are exercised. The equity component of convertible loan stock, if any, is 
also included. On conversion of the loan stock the equity component is transferred into the 
retained earnings reserve. 

l  “Foreign exchange reserve” represents the differences arising from translation of investments in 

overseas subsidiaries.

l  “Retained earnings” represents retained profits. 

Contributions to pension schemes
Defined Contribution Scheme
Obligations for contributions for defined contribution plans are recognised as an expense in the 
income statement when they are due.

Financial assets
The Group’s financial assets comprise trade receivables, other receivables, cash and cash 
equivalents. Trade and other receivables are recognised and carried at the original invoice amount 
less a provision for the expected credit loss. Management have adopted the simplified model to 
determine the expected credit loss on trade receivables and uses historical experience of losses 
applied to the specific circumstances of the receivable, including trading history with the debtor 
and period overdue to determine the need for and amount of any provision to cover expected 
future losses. Uncollectable amounts are written off to the Income Statement when identified. 

Financial liabilities
Financial liabilities are obligations to pay cash or other financial assets and are recognised when the 
Group becomes a party to the contractual provisions of the instrument. The Group’s financial 
liabilities comprise trade payables, other payables, other loans and bank borrowings. All financial 
liabilities are measured at fair value plus transaction costs on initial recognition and subsequently 
are measured at amortised cost. Contingent consideration assumed in a business combination is 
measured initially at fair value through profit and loss in the income statement at the acquisition 
date and any contingent liability is classified as a liability within the balance sheet.

Financial Statements     64/65

Principal Accounting Policies (continued)   

Revenue recognition
In accordance with IFRS 15 ‘Revenues from Contracts with Customers’, revenue is measured by 
reference to the fair value of consideration received or receivable by the Group, excluding value 
added tax (or similar local sales tax), in exchange for transferring the promised goods or services to 
the customer. The consideration is allocated to each separate performance obligation that is 
identified in a sales contract, based on stand-alone selling prices. Sales of instruments and spare 
parts, and sales of services, such as non-specialised installation or maintenance work, are assessed 
to be separate performance obligations.

Revenue is recognised when (or as) the Group satisfies the identified performance obligation. For 
sales of instruments and spare parts, the performance obligation is satisfied at a point in time; for 
revenue from services, the performance obligation is satisfied over time. As the period of time 
between payment and performance is less than one year, the Group does not adjust revenue for 
the effects of financing.

Revenue from sales of instruments and spare parts is recognised at the point at which the 
customer obtains control of the asset. This is usually when the customer receives the goods or 
when goods are collected by the customer. Revenue from installations is recognised at the point 
which the installation is completed. For large, complex instruments which require highly specialised 
installation, revenue from both the instrument and installation is recognised at the point which 
installation is completed.

Revenue from maintenance work relates to service visits carried out on equipment provided to 
customers whereby the performance obligation is to carry out service visits over a period of time.  
It is a separate, distinct, individually identified performance obligation and is recognised straight-
line over the length of the service contract being provided as this reflects the inputs and efforts 
(service employees) which are expended evenly throughout the performance period (length of t 
he contract). 

Leased assets
The Group makes the use of leasing arrangements principally for the provision of the main 
warehouse and related facilities, office space, IT equipment and motor vehicles. The rental 
contracts for offices are typically negotiated for terms of between 5 and 20 years and some of 
these have extension terms. Lease terms for office fixtures and equipment and motor vehicles  
have lease terms of between 6 months and 5 years without any extension terms. The Group does 
not enter into sale and leaseback arrangements. All the leases are negotiated on an individual basis 
and contain a wide variety of different terms and conditions such as purchase options and 
escalation clauses.

The Group assesses whether a contract is or contains a lease at inception of the contract. A lease 
conveys the right to direct the use and obtain substantially all of the economic benefits of an 
identified asset for a period of time in exchange for consideration.

Measurement and recognition of leases as a lessee
At lease commencement date, the Group recognises a right-of-use asset and a lease liability  
in its consolidated statement of financial position. The right-of-use asset is measured at cost, 
which is made up of the initial measurement of the lease liability, any initial direct costs incurred 
by the Group, an estimate of any costs to dismantle and remove the asset at the end of the lease, 
and any lease payments made in advance of the lease commencement date (net of any 
incentives received).

The Group depreciates the right-of-use asset on a straight-line basis from the lease commencement 
date to the earlier of the end of the useful life of the right-of-use asset or the end of the lease term. 
The Group also assesses the right-of-use asset for impairment when such indicators exist.

At the commencement date, the Group measures the lease liability at the present value of the lease 
payments unpaid at that date, discounted using the Group’s incremental borrowing rate because as 
the lease contracts are negotiated with third parties it is not possible to determine the interest rate 
that is implicit in the lease. 

The incremental borrowing rate is the estimated rate that the Group would have to pay to borrow 
the same amount over a similar term, and with similar security to obtain an asset of equivalent 
value. This rate is adjusted should the lessee entity have a different risk profile to that of the Group. 

Lease payments included in the measurement of the lease liability are made up of fixed payments 
(including in substance fixed), variable payments based on an index or rate, amounts expected to 
be payable under a residual value guarantee and payments arising from options reasonably certain 
to be exercised.

Subsequent to initial measurement, the liability will be reduced by lease payments that are 
allocated between repayments of principal and finance costs. The finance cost is the amount that 
produces a constant periodic rate of interest on the remaining balance of the lease liability. 

The lease liability is reassessed when there is a change in the lease payments. Changes in lease 
payments arising from a change in the lease term or a change in the assessment of an option to 
purchase a leased asset. The revised lease payments are discounted using the Group’s incremental 
borrowing rate at the date of reassessment when the rate implicit in the lease cannot be readily 
determined. The amount of the remeasurement of the lease liability is reflected as an adjustment to 
the carrying amount of the right-of-use asset. The exception being when the carrying amount of 
the right-of-use asset has been reduced to zero then any excess is recognised in profit or loss.

To respond to business needs particularly in the demand for office space, the Group will enter into 
negotiations with landlords to either increase or decrease available office space or to renegotiate 
amounts payable under the respective leases. In some instances, the Group is able to increase 
office capacity by taking additional floors available and therefore agrees with the landlord to pay  
an amount that is commensurate with the stand-alone pricing adjusted to reflect the particular 
contract terms. In these situations, the contractual agreement is treated as a new lease and 
accounted for accordingly.

In other instances, the Group is able to negotiate a change to a lease such as reducing the amount 
of office space taken, reducing the lease term or by reducing the total amount payable under the 
lease. Both of which were not part of the original terms and conditions of the lease. In these 
situations, the Group does not account for the changes as though there is a new lease. Instead,  
the revised contractual payments are discounted using a revised discount rate at the date the 
parties agree to the modification. For the reasons explained above, the discount rate used is the 
Group’s incremental borrowing rate determined at the modification date, as the rate implicit in  
the lease is not readily determinable.

The remeasurement of the lease liability is dealt with by a reduction in the carrying amount of the 
right-of-use asset to reflect the full or partial termination of the lease for lease modifications that 
reduce the scope of the lease. Any gain or loss relating to the partial or full termination of the lease 
is recognised in profit or loss. The right-of-use asset is adjusted for all other lease modifications.

Taxation
Income tax expense comprises current and deferred tax.

The tax currently payable is based on the taxable profit for the year. Current tax is recognised in 
profit or loss, except that current tax relating to items recognised in other comprehensive income 
is recognised in other comprehensive income and current tax relating to items recognised directly 
in equity is recognised in equity. Taxable profit differs from 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.

Principal Accounting Policies (continued) 
Taxation (continued) 
Deferred tax is recognised on differences between the carrying amounts of assets and liabilities in 
the financial statements and the corresponding tax bases used in the computation of taxable profit 
It is accounted for using the balance sheet liability method. However, deferred tax is not provided 
on the initial recognition of goodwill, or on the initial recognition of an asset or liability unless the 
related transaction is a business combination or affects tax or accounting profit. 

Deferred tax on temporary differences associated with investments in subsidiaries is not provided  
if reversal of these temporary differences can be controlled by the Group or it is probable that 
reversal will not occur in the foreseeable future. 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 the temporary difference can be utilised.

The carrying value of deferred tax asset is reviewed at each balance sheet date and reduced to the 
extent that it is no longer probable that sufficient taxable profits will be available to allow part or all 
of the assets to be recovered.

Deferred tax is calculated using tax rates that are enacted or substantively enacted at the balance 
sheet date. Deferred tax is charged or credited to the income statement, except when it relates  
to items charged or credited directly to equity, in which case the deferred tax is also dealt with in 
equity. Deferred tax relating to items recognised in other comprehensive income is recognised  
in other comprehensive income.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off 
current tax assets against current tax liabilities and when they relate to income taxes levied by  
the same taxation authority and the Group intends to settle its current tax assets and liabilities on  
a net basis.

Segment reporting
The Group identifies operating segments based on internal management reporting that is regularly 
reviewed by the chief operating decision maker. The chief operating decision maker is the 
Executive Board of Directors.

Provisions
Provisions are recognised when present obligations as a result of a past event will probably lead to 
an outflow of economic resources from the Group and the amounts can be estimated reliably. 

A provision for warranties is recognised when the underlying products are sold. The provision is 
based on historical warranty data and a weighting of possible outcomes against their associated 
probabilities.

Share-based payments
SDI Group plc regularly issues share options to employees. The fair value of the award granted is 
recognised as an employee expense within the Income Statement with a corresponding increase in 
equity. The fair value is measured at the grant date and allocated over the vesting period based on 
the best available estimate of the number of share options expected to vest. Estimates are 
subsequently revised if there is any indication that the number of share options expected to vest 
differs from previous estimates. 

The fair value of the grants is measured using the Black-Scholes model or a Monte Carlo simulation 
as appropriate, taking into account the terms and conditions upon which the grants were made. 

Alternative Performance Measures 

4

The Group uses Adjusted Operating Profit, Adjusted Profit Before Tax, Adjusted Diluted EPS and Net 
Operating Assets as supplemental measures of the Group’s profitability and investment in business-
related assets, in addition to measures defined under IFRS. The Group considers these useful due to 
the exclusion of specific items that are considered to hinder comparison of underlying profitability 
and investments of the Group’s segments and businesses and is aware that shareholders use these 
measures to evaluate performance over time. The adjusting items for the alternative measures of 
profit are either recurring but non-cash charges (share-based payments and amortisation of 
acquired intangible assets) or exceptional items (reorganisation costs and acquisition costs).

The following table is included to define the term Adjusted Operating Profit:

Adjusted Operating Profit has been defined in note 4. 

Analysis of amortisation of acquired intangible assets has been included separately as the  
Group considers it to be an important component of profit which is directly attributable to  
the reported segments.

The Other category includes costs which cannot be allocated to the other segments and  
consists principally of Group head office costs.

Financial Statements     72/73

Share-based employee remuneration
The company has two active EMI option schemes, “approved” and “unapproved”, which share 
similar features, but may be treated differently regarding taxation of the option holder. Both 
schemes have been approved by shareholders in general meetings. The approved scheme has 
been approved by HM Revenue & Customs. The options can be exercised three years after the 
share options are granted. Upon vesting, each option allows the holder to purchase one ordinary 
share. The options lapse if share options remain unexercised after a period of 10 years after the 
date of grant or if the employee leaves. During the year, 791,000 of such options were granted 
under these schemes, at exercise prices ranging from £1.650 to £1.740. The weighted average 
remaining contractual life of all outstanding options under these schemes is 6.35 years.

In addition, in December 2018, a Long-Term Incentive Plan (LTIP) was approved by the Board  
of Directors. Under the terms of the grant, a proportion of the options will vest after three years, 
depending on a) the ranking of Total Shareholder Return (TSR) to Group shareholders compared 
with a basket of twenty comparator companies, and b) the earnings per share growth for the 
Group over the three-year period. The exercise price for these options is 1p each, being the 
nominal value of SDI shares.

A summary of options outstanding currently is as follows:

In accordance with IFRS 2, share-based compensation expense is calculated on the issue of  
share options. For options under the LTIP scheme vesting based on TSR, a Monte Carlo  
simulation performed is used to value the compensation expense. For the other options issued 
during the year, the compensation expense was valued using the Black Scholes model, with the 
following inputs:

l  interest rate  1%-1.8%

l  volatility  46%-48%

l  expected life of option  3 years.

The charge for the year ended 30 April 2022 was £313k (2021: £305k).

The Group takes advantage of the enhanced tax deductions for Research and Development 
expenditure in the UK and expects to continue to be able to do so. 

The UK Finance Act 2021 which was substantively enacted on 24 May 2021 included provisions to 
increase the corporation tax rate to 25% effective from 1 April 2023 and this rate has been applied 
when calculating the deferred tax at the year end.

Capitalised development costs include amounts totalling £31k (2021: £429k) relating to incomplete 
projects for which amortisation has not yet begun.

Goodwill relates to various acquisitions and has been allocated to each cash generating unit as 
appropriate. The cash generating units used to test impairment are generally the individual 
acquired businesses, or, where these have been operationally merged with others, the resulting 
merged businesses. Goodwill is not amortised but tested for impairment annually with the 
recoverable amount being determined from value in use calculations. Goodwill has been allocated 
for impairment testing to each Cash Generating Unit (CGU), as follows:

Synoptics
Atik
Graticules
Sentek
Astles Control Systems
Applied Thermal Control
MPB Industries
Chell Instruments
Monmouth Scientific incorporating Uniform Engineering and

The individual impairment assessments for the cash generating units were based on value-in-use 
calculations covering a five-year forecast followed by an extrapolation of expected cash flows to 
perpetuity using a long-term growth rate of 2%.

Right-of-Use Leased Assets

A risk-adjusted, pre-tax discount rate of 13.6% (2021: 13.7%) which was judged to be appropriate for 
each of the CGUs given that they operate in similar markets and the risk profiles are similar. 
Management’s key assumption for all cash generating units and resulting cash flows is to maintain 
market share in their markets. 

The Directors have concluded that Goodwill is not impaired for any of the cash generating units. 
They have further considered the sensitivity of the key assumptions which were most sensitive to 
changes, including reduced growth rates and operating margins, and increased discount rates.  
The Growth rates are based on economic data for the wider economy and represent a prudent 
expectation of growth. 

Management has performed a sensitivity analysis for the Monmouth Scientific CGU for which with 
the base assumptions there is a 13% headroom of value in use above carrying cost of the CGU, and 
for which reasonably possible, but not probable, changes in the key assumptions could give rise to 
an impairment. 

If any one of the following occurred, the headroom would disappear:

l  discount rate increased to from 13.6% to 15.1%

l  sales volume reduced by 3.5%, with no action on costs

l  operating margins reduced by 1.8% 

The average remaining amortisation period of intangible assets excluding Goodwill is 10.1 years 
(2021: 7.8 years).

The Group has leases for the main factory buildings and offices, and for some vehicles and 
equipment. With the exception of short-term leases and leases of low-value underlying assets, 
each lease is reflected on the balance sheet as a right-of-use asset and a lease liability. Variable 
lease payments which do not depend on an index or a rate are excluded from the initial 
measurement of the lease liability and asset. The Group classifies its right-of-use assets in a 
consistent manner to its property, plant and equipment (see note 12).

Each lease generally imposes a restriction that, unless there is a contractual right for the Group to 
sublet the asset to another party, the right-of-use asset can only be used by the Group. Leases are 
either non-cancellable or may only be cancelled by incurring a substantial termination fee. For 
leases over office buildings and factory premises the Group must keep those properties in a good 
state of repair and return the properties in their original condition at the end of the lease. 
Furthermore, the Group must insure items of plant and machinery and incur maintenance fees on 
such items in accordance with the lease contracts.

The lease liabilities are secured by the related underlying assets. Total contractual undiscounted 
lease liabilities at 30 April 2022 were as follows:

Within one year
Within two to five years
After five years

During the previous year, the Group was committed to a long-term lease of the new custom-built 
factory building at Monmouth Scientific and the total commitment at that date was £4.6m. The 
building was occupied during the current year and the liabilities and assets were recognised in line 
with this.

Lease payments not recognised as a liability
The Group has elected not to recognise a lease liability for short term leases (leases with an 
expected term of 12 months or less) or for leases of low value assets. Payments made under such 
leases are expensed on a straight-line basis. In addition, certain variable lease payments are not 
permitted to be recognised as lease liabilities and are expensed as incurred.

Deferred tax assets are recognised for tax losses available for carrying forward to the extent that the 
realisation of the related tax benefit through future taxable profits is probable. The Group did not 
recognise deferred tax assets of £260k (2021: £198k) in respect of losses. These losses are all pre-1 
April 2017 and therefore cannot be offset against trading profits of the same trade post 1 April 2017. 
Total losses (provided and unprovided) totalled £1.3m (2021: £1.5m). 

The Group benefits from tax deductions related to actual gains made by employees on exercise of 
share options, which are different, in both magnitude and timing, from the share-based payments 
expense recorded in the Group’s Income Statement (for which no tax deduction is received).  
A deferred tax asset is recorded for the tax deductions expected to result from future share option 
exercises, based on the calculated earned gains inherent in share options outstanding at period 
end, at the current enacted tax rate. To the extent that the deductible employee gains exceed the 
recorded share-based payments, the excess of the associated current or deferred tax is recognised 
directly in equity. Tax deductions totalling £357k (2021: £1,438k) have been recognised directly  
in equity.

Accruals and deferred income includes an amount of £5,533k (2021: £3,875k) in respect of 
contract liabilities for revenues relating to performance obligations expected to be satisfied within 
the next 12 months. The contract liabilities balance has increased during the year principally due  
to contract liabilities of acquired subsidiaries. All the prior year contract liabilities of £3,875k were 
recognised as revenue during the current year.

At the end of the year, contingent consideration of £961k was outstanding in relation to the 
acquisition of Scientific Vacuum Systems Limited, and still remains outstanding. Deferred 
consideration of £2,344k was outstanding in relation to the acquisition of Safelab Systems Limited, 
which has since been paid to the sellers.

All amounts are short-term. The carrying values are considered to be a reasonable approximation 
of fair value.

In addition, some of the unimpaired trade receivables are past due at the reporting date. There are 
no indications that financial assets past due but not impaired are irrecoverable.

The Directors consider that the carrying amount of trade and other receivables approximates to 
their fair value.

Warranties of between one and three years are given with the sales of products. There are potential 
costs associated with the repair of goods under these warranties which could occur at any time 
over the next three years of which the level of costs is uncertain. The warranty provision is based 
on the historical cost of warranty repairs over the last three years, and it is expected that the 
majority of this expenditure will be incurred in the next financial year. During the year the Group 
acquired Scientific Vacuum Systems Limited and as part of these acquisition, dilapidations of £30k 
have been provided for.

Bank finance relates to amounts drawn down under the Group’s bank facility with HSBC Bank plc, 
which is secured against all assets of the Group. Until 01 November 2021, the facility consisted of  
a revolving facility of £5.0m and an amortising facility which reduced in quarterly instalments from 
£4.8m when it was taken out in November 2019 to zero by November 2024, when the agreement 
was due to expire. On 01 November 2021 the Group renewed and expanded its committed loan 
facility with HSBC to £20m, with a further accordion option of an additional £10m (at the discretion 
of HSBC), and with repayment date of November 2024 extendable for two further years. The 
revolving facility is available for general use. The facility has covenants relating to leverage (net debt 
to EBITDA) and interest coverage.

During the year 3,673,796 Ordinary shares of 1p were issued due to the exercise of options and 
117,716 Ordinary shares of 1p were issued to part fund the acquisition made during the year.  
The 3,673,796 options had an exercise price ranging from £0.010 to £1.740. The Group received 
£651k cash for the option exercises as well as offsetting £200k against the acquisition of Safelab 
Systems Limited. The £851k consideration received was allocated £38k to share capital and £813k 
to share premium. 

Earnings Per Share 

The calculation of the basic earnings per share is based on the profits attributable to the 
shareholders of SDI Group plc divided by the weighted average number of shares in issue during 
the period. All profit per share calculations relate to continuing operations of the Group.

Basic earnings per share:
  – Year ended 30 April 2022

Performance guarantees totalling £32k (2021: £32k) are held by the bank. These would become 
payable by the Group if, once the customer has placed an order, the Group fails to deliver goods to 
the customer.

Financial Risk Management Objectives and Policies

Financial instruments
The Group uses various financial instruments, including loans and leasing arrangements, and has 
certain assets and liabilities which are denominated in foreign currencies. The main purpose of the 
financial instruments is to raise finance for the Group’s operations. The existence of these financial 
instruments and other financial assets and liabilities exposes the Group to a number of financial 
risks, primarily interest rate risk and currency risk. 

Interest rate risk
The Group finances its operations through a mixture of retained profits, short-term and long-term 
bank borrowings, and shareholders’ equity. The Group has an exposure to interest rate fluctuations 
on its borrowings which are generally linked to SONIA. An increase in SONIA of 1% would result in 
an increase in interest costs of approximately £40k (2021: £31k) annually, based on the loan 
outstanding at 30 April 2022.

Currency risk
A significant proportion of the Group’s monetary assets (principally bank balances and trade 
receivables) and liabilities (principally borrowings) are denoted in Dollars and Euros but held in 
entities with Sterling as the functional currency. An adverse movement in exchange rates could 
lead to losses on these positions. As at 30 April 2022 an adverse movement in the dollar of 5% 
would result in a reduction in the Group’s equity and profit or loss of £49k (2021: £62k). An adverse 
movement in the Euro of 5% would result in a reduction in the Group’s equity and profit or loss of 
£115k (2021: £64k).

The carrying amount of the Group’s Dollar and Euro-denominated monetary assets with a differing 
functional currency at the reporting date is as follows:

US Dollars
Euros

 Assets

2022
 £’000

1,035
2,416

2021
 £’000

1,303
1,354

In addition to this, significant proportions of the Group’s revenue, purchases and overhead costs 
are transacted in foreign currencies, mainly Dollars and Euros. The Group does not attempt to 
hedge its exposure using derivative instruments.

Credit risk
The Group’s exposure to credit risk is limited to the carrying amount of cash deposits and trade  
and other receivables recognised at the balance sheet date of £12,669k (2021: £10,757k). Risks 
associated with cash deposits are limited as the banks used are reputable with quality external 
credit ratings.

The principal credit risks lie with trade receivables. In order to manage credit risk credit limits are 
set for customers based on a combination of payment history and third-party credit references. 
Details of overdue trade receivables are provided below. All of the receivables have been reviewed 
for potential credit losses, and expected credit loss has been estimated, as set out in note 16.  
The simplified approach has been adopted to calculate the level of expected credit loss provision  
in the year with a 30% allowance applied to those debtors due between 90 days and 120 days and 
a 70% allowance applied to those debtors greater than 120 days old.

Liquidity risk
Liquidity risk is that the Group might be unable to meet its obligations and arises from trade and 
other payables. The Group manages liquidity risk by maintaining adequate reserves and banking 
facilities and by continuously monitoring forecasts and actual cash flows. 

The Group’s financial liabilities have contractual maturities as summarised below:

Capital Management Policies and Procedures

The Group’s capital management objectives are:

l  to ensure the Group’s ability to continue as a going concern; and

l  to provide an adequate return to shareholders; and

l  to be in a position to make acquisitions (‘buy and build’ strategy)

The Group monitors capital by tracking and forecasting its Debt-to-EBITDA ratio as required by its 
bank facility covenant. The Group has historically acquired companies using a combination of cash 
on hand, increased borrowing, issue of shares to the sellers, and new equity share placings, taking 
care to retain adequate liquidity reserves.

The Group has not paid dividends but will keep its dividend policy under review.

On 5 January 2022, the Company acquired 100% of the share capital of Scientific Vacuum Systems 
Limited, a company incorporated in England and Wales, for a consideration payable in cash, 
including an earnout element dependent on financial performance to September 2022.

Group’s profit before tax for the period between the date of acquisition and the balance sheet date, 
not including £133k of acquired intangible asset amortisation.

If the acquisition of Scientific Vacuum Systems Limited had been completed on the first day of the 
financial year, the additional impact on group revenues for the period would have been £1,499k 
and the additional impact on group profit would have been approximately £437k, before additional 
£267k of amortisation expense.

The goodwill of £2,444k arising from the acquisition relates to the assembled workforce and to 
expected future profitability, synergy and growth expectations.

Financial Statements     88/89

Safelab Systems Limited contributed £522k revenue and approximately £98k to the Group’s profit 
before tax for the period between the date of acquisition and the balance sheet date, not including 
£68k of acquired intangible asset amortisation.

If the acquisition of Safelab Systems Limited had been completed on the first day of the financial 
year, the additional impact on group revenues for the period would have been £4,730k and the 
additional impact on group profit would have been approximately £713k, before additional £342k 
of amortisation expense.

The goodwill of £3,561k arising from the acquisition relates to the assembled workforce and to 
expected future profitability, synergy and growth expectations.

Management performed a detailed review of the acquired intangible assets, and recognised 
acquired customer relationships, tradename and order book. The customer relationships intangible 
asset was valued using a multi-period excess earnings methodology. The estimated fair value of 
the customer relationships therefore reflects the present value of the projected stream of cash 
flows that are expected to be generated by existing customers going forwards, net of orders on 
hand at the date of acquisition. Key assumptions are the discount rate and attrition rate. Values of 
14.8% and 20% were selected.

A total of 117,716 shares were issued for consideration for £200k.

The deferred tax liability has been calculated on the amortisable intangible assets using the current 
enacted statutory tax rate of 25%.

The last financial year for Safelab Systems Limited before the acquisition closed was to 28 February 
2022. The current financial year has been extended by two months to April 2023 to align with that 
of SDI Group plc.

Business Combinations (continued) 

A third party performed a detailed review of the acquired intangible assets and recognised acquired 
customer relationships and order book. The customer relationships intangible asset was valued 
using a multi-period excess earnings methodology. The estimated fair value of the customer 
relationships therefore reflects the present value of the projected stream of cash flows that are 
expected to be generated by existing customers going forwards, net of orders on hand at the date 
of acquisition. Key assumptions are the discount rate and attrition rate. Values of 16.7% and 10% 
were selected.

The deferred tax liability has been calculated on the amortisable intangible assets using the current 
enacted statutory tax rate of 25%.

The last financial year for Scientific Vacuum Systems Limited before the acquisition closed was to 
30 September 2021. The current financial year has been shortened by five months to April 2022 to 
align with that of SDI Group plc.

On 24 March 2022, the Company acquired 100% of the share capital of Safelab Systems Limited,

Notes to the Company Financial Statements  
for the year ended 30 April 2022

1 

Principal Accounting Policies 

Basis of preparation
The separate financial statements were prepared in accordance with Financial Reporting Standard 
101 Reduced Disclosure Framework. The financial statements are prepared under the historical 
cost convention.

Disclosure exemptions adopted
In preparing these financial statements the Company has taken advantage of all disclosure 
exemptions conferred by FRS 101. Therefore, these financial statements do not include:

l  A statement of cash flows and related notes

l  The requirements of IAS 24 related party disclosures to disclose related party transactions entered 

between two or more members of the group as they are wholly owned within the group.

l  Disclosure of key management personnel compensation

l  Capital management disclosures 

l  Presentation of comparative reconciliation of the number of shares outstanding at the beginning 

and at the end of the period

l  The effect of future accounting standards not adopted

l  Certain share-based payment disclosures

l  Disclosures in relation to impairment of assets

l  Financial instrument disclosures under IFRS 9

Investments
SDI Group plc qualifies for merger relief under Companies Act 2006 s612 and has recorded the 
investment in Synoptics Limited at the nominal value of the shares issued, less provision for 
impairment. The shares issued on acquisition of Opus Instruments Limited also qualified for merger 
relief under Companies Act 2006 s612 and so the premium has been classified as a merger relief 
reserve. All other investments are recorded at cost, less any provision for impairment.

Other intangible assets
Intangible assets acquired as part of an acquisition of a business are capitalised separately from 
goodwill providing the assets are separable or they arise from contractual or other legal rights and 
their fair value can be measured reliably. The fair value of intangible assets in a business 
combination includes the value of any tax benefit.

Share options
SDI Group plc regularly issues share options to employees, including to employees of subsidiary 
companies. The fair value of the employee services received in exchange for the grant of options is 
recognised as an expense which is written off to the income statement over the vesting period of 
the option. The amount to be expensed is determined by reference to the fair value of the options 
at the grant date adjusted for the number expected to vest. The expense relating to these options is 
recognised in the relevant subsidiary company income statement. The carrying value of the 
investment in those subsidiaries is increased by an amount equal to the value of share-based 
payment charge attributable to the option holders in the respective subsidiaries. 

Taxation
Deferred tax is recognised on differences between the carrying amounts of assets and liabilities in 
the financial statements and the corresponding tax bases used in the computation of taxable profit 
It is accounted for using the balance sheet liability method. However, deferred tax is not provided 
on the initial recognition of goodwill, or on the initial recognition of an asset or liability unless the 
related transaction is a business combination or affects tax or accounting profit. 

Financial Statements     92/93

Deferred tax on temporary differences associated with investments in subsidiaries is not provided  
if reversal of these temporary differences can be controlled by the Group or it is probable that 
reversal will not occur in the foreseeable future. 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 the temporary difference can be utilised.

The carrying value of deferred tax asset is reviewed at each balance sheet date and reduced to the 
extent that it is no longer probable that sufficient taxable profits will be available to allow part or all 
of the assets to be recovered.

Deferred tax is calculated using tax rates that are enacted or substantively enacted at the balance 
sheet date. Deferred tax is charged or credited to the income statement, except when it relates to 
items charged or credited directly to equity, in which case the deferred tax is also dealt with in 
equity. Deferred tax relating to items recognised in other comprehensive income is recognised in 
other comprehensive income.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current 
tax assets against current tax liabilities and when they relate to income taxes levied by the same 
taxation authority and the Group intends to settle its current tax assets and liabilities on a net basis.

Financial instruments
Financial liabilities and equity instruments are classified according to the substance of the 
contractual arrangements entered into. An equity instrument is any contract that results in a residual 
interest in the assets of the Company after deducting all of its financial liabilities. Equity instruments 
do not include a contractual obligation to deliver cash or other financial asset to another entity.

Any instrument that does have the obligation to deliver cash or another financial asset to another 
entity is classified as a financial liability. Financial liabilities are presented under creditors on the 
balance sheet.

Pension
The pension costs charged against profits represent the amount of the contribution’s payable to 
the defined contribution scheme in respect of the accounting period.

Borrowings
Borrowings are recognised initially at fair value, net of transaction costs incurred. Borrowings are 
subsequently stated at amortised cost. Any difference between the proceeds and the redemption 
value is recognised in the income statement over the period of the borrowings using the effective 
interest method. Borrowings are classified as current liabilities unless the Group has an 
unconditional right to defer settlement of the liabilities for at least 12 months after the balance 
sheet date. 

Equity
Equity comprises the following:

l  “Share capital” represents the nominal value of equity shares

l  “Merger relief reserve” represents the difference between the parent company’s cost of 

investment and the subsidiary’s share capital and share premium where a group reorganisation 
qualifies as a common control transaction.

l  “Share premium account” represents the excess over nominal value of the fair value of 

consideration received for equity shares, net of expenses of the share issue.

l  “Share-based payment reserve” represents equity-settled share-based employee remuneration 

until such share options are exercised. The equity component of convertible loan stock, if any, is 
also included. On conversion of the loan stock the equity component is transferred into the 
retained earnings reserve. 

l  “Retained earnings” represents retained profits.

Deferred tax assets are recognised for tax losses available for carrying forward to the extent that the 
realisation of the related tax benefit through future taxable profits is probable. The Group did not 
recognise deferred tax assets of £260k (2021: £198k) in respect of losses. Total losses (provided and 
unprovided) totalled £1.3m (2021: £1.5m). These losses are all pre-1 April 2017 and therefore 
cannot be offset against trading profits of the same trade post 1 April 2017.

The deferred tax asset relates to tax deductions for share options as they are exercised.

Bank finance relates to amounts drawn down under the Group’s bank facility with HSBC Bank plc, 
which is secured against all assets of the Group. Until 01 November 2021, the facility consisted of a 
revolving facility of £5.0m and an amortising facility which reduced in quarterly instalments from 
£4.8m when it was taken out in November 2019 to zero by November 2024, when the agreement 
was due to expire. On 01 November 2021 the Group renewed and expanded its committed loan 
facility with HSBC to £20m, with a further accordion option of an additional £10m (at the discretion 
of HSBC), and with repayment date of November 2024 extendable for two further years. The 
revolving facility is available for general use. The facility has covenants relating to leverage (net debt 
to EBITDA) and interest coverage.
