SDI Group plc 
Strategic Report 2023

Chairman’s Statement 
for the year ended 30 April 2023 

”I am pleased to report that SDI has delivered 
another record year in terms of revenues 
and adjusted EBIT. This was despite a volatile 
economic environment, with high inflation, a 
tight labour market and an unpredictable supply 
chain. Our agile business model, which involves 
smaller niche autonomous businesses operating 
in a multitude of markets, gives us the ability to 
respond quickly to market movements and is a 
strength during periods of economic turbulence.“

KEN FORD

Performance

The Group continues to deliver on 
its buy and build strategy, adding two 
new businesses during the financial 
year whilst most existing businesses 
within the Group also performed well.

On 29 July 2022, we completed 
the acquisition of LTE Scientific 
Limited (‘LTE’), a UK company which 
specialises in the design, manufacture 
and servicing of sterilizers, 
decontamination and thermal 
processing equipment, used in the 
life science and medical sectors. On 
21 October 2022, the Group acquired 
Fraser Anti-Static Techniques Limited 
(‘FAST’), a leading UK manufacturer of 
anti-static products which eliminate, 
clean, generate or measure static 
electricity in a variety of industries 
including plastics, packaging and 
printing, amongst others. FAST’s 
technologies and markets are 
unrelated to our current portfolio. 
However, LTE operates in a market 
with which we are already familiar. 
Both companies fit perfectly within 
our acquisition criteria and have 
become part of our Sensors and 
Control segment.  

These businesses will be operated 
separately from our existing 
businesses. We warmly welcome our 
new colleagues to the SDI Group.

Adjusted profit before tax at £11.8m 
remained the same as the previous 
year. Adjusted operating profit 
improved by 5.8% to £12.8m. 

These acquisitions were funded  
from existing cash resources and 
debt facilities. Both companies  
have performed well since joining 
the Group.

The Group reported full year  
revenues of £67.6m, an increase 
of 36.0% from FY22 (£49.7m). 
SDI benefitted from a full year’s 
contribution from both Scientific 
Vacuum Systems (acquired January 
2022) and Safelab Systems (March 
2022) as well as the FY23 acquisitions 
noted above. Atik Camera’s one-off 
business with an overseas OEM for 
PCR cameras generated £8.5m of 
revenues in FY23, compared with 
£10.9m in FY22. This business came 
to an end in February 2023 and as 
previously announced there are 
unlikely to be any further contracts 
with this customer. Group organic 
revenue growth for the year was 
0.9%, and excluding the one-off 
contracts and the impact of FX, SDI 
generated 6.4% organic growth.

As you will read elsewhere in this 
report, we have written off the 
Monmouth Scientific and Uniform 
Engineering goodwill and £0.3m of 
the two businesses’ intangible assets. 
The total non-cash impairment 
charge, net of applicable deferred tax, 
is £3.4m whilst the gross impairment 
charge is £3.5m. Whilst this is not 
ideal, we remain confident in 
Monmouth’s future prospects. Its net 
profit margins have reduced  
following the end of the pandemic, 
however the business has remained 
profitable and has a capable new 
management team. 

The impairment, together with higher 
intangible amortisation and interest 
charges, has meant the statutory 
operating profit has reduced from 
£10.2m in FY22 to £6.8m this year. 
Statutory profit before tax has 
reduced from £9.9m last year to 
£5.8m in FY23.

Strategy

We 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 and strong 
existing management teams that have 
sustainable profits and cash flows and 
the potential to grow. 

We continue to service many sectors 
and geographies with SDI products, 
particularly in the industrial products, 
life sciences and medical sectors. Our 
exposure to discretionary consumer 
spending is limited and our sales 
directly to government entities are 
not high. And whilst not immune to 
economic conditions, we benefit 
from structural tailwinds in a number 
of our businesses.

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 have 
started to take tangible steps in 
the last six months to evaluate our 
environmental, social and  
governance (‘ESG’) position. This is 
outlined further in the ESG section  
of the annual report.

SDI is often asked about its head office 
structure. This has been in place over 
the last decade, but at the same time, 
both the CEO and myself have worked 
in close tandem when evaluating 
potential acquisitions. We have an 
experienced Board, all of whom have 
significant M&A knowledge, and 
this has been strengthened over the 
financial year. However, the Board 
is very aware of SDI’s resourcing 
structure and continues to evaluate 
whether additional skill sets are 
required to continue growth, both 
organically and through acquisition. 

Board

Outlook

The Group has added two high quality 
businesses to the portfolio in FY23. 
We continue to execute our proven 
value-creating business model by 
investing in capacity and capability 
to enable organic growth amongst 
our portfolio of businesses, as well as 
buying and building where acquisition 
opportunities present themselves.

Against the backdrop of an uncertain 
economic environment, the portfolio 
effect of a group of agile businesses 
operating in multiple markets  
remains an effective strategy in 
delivering organic growth. We will 
continue to build through acquisition, 
and we will look to unlock synergies 
within our portfolio of businesses. 
While we are mindful of the 
challenging external environment, we 
remain optimistic for the year ahead 
and we expect to deliver FY24 results 
in line with expectations.

Ken Ford
Chairman 
7 August 2023

Our new CFO, Ami Sharma, joined 
the Board in August 2022 taking 
over from Jon Abell, who retired in 
September after a handover period. 

We are also pleased to welcome both 
Andrew Hosty and Louise Early to 
the Board as non-executive directors 
this year. Andrew joined in August 
and Louise started in February. Both 
Andrew and Louise have had lengthy 
careers in decentralised industrial 
companies, and we are already seeing 
the benefits of their experience.

Team

SDI employs over 500 people across 
its companies. It has been another 
challenging year for the Group 
and its employees. COVID has not 
completely gone away. Recruitment 
challenges, an unpredictable supply 
chain as well as inflation have made 
the business environment tricky to 
navigate for our staff. On behalf of the 
Board, I would offer our appreciation 
and thanks for all our employees’ 
dedication and efforts throughout 
the year. I would also like to thank the 
wider head office team including CFO 
Ami Sharma and our Group Financial 
Controller for their efforts over the 
last year. Our employees’ skills and 
experience are key to the long-term 
sustainability of our businesses.

Brexit and COVID-19 have 
heavily impacted upon our 
last three years of trading. 
The pandemic created both 
challenges and opportunities 
for the Group and active 
management has allowed 
the Group to generate very 
strong revenues and profits, 
with the last of the Atik sales 
of cameras for PCR machines 
being despatched to China in 
February 2023. The Group’s 
future organic growth rates 
are expected to normalise to 
within the 5%-10% range in 
the absence of exceptional 
revenues and profits. 

Brexit has impacted upon the 
Group, with delays exporting to and 
importing from Europe often causing 
disruption, but we are now seeing 
this as less of an issue. As with all 
UK companies, both staffing and 
inflation have had an impact on our 
businesses but staff recruitment is 
improving with few open vacancies 
remaining. We have passed on price 
increases from our supply chain to 
our customers with some success.

Revenues and Profits

Overall revenues grew by 36.0%, 
of which 35.1% was from the full 
year impact of the FY22 acquisitions 
of Scientific Vacuum Systems and 
Safelab Systems and from the 
contributions of LTE Scientific and 
Fraser Anti-Static Techniques, both 
of which were acquired in the year.  
Adjusted operating profit grew  
by 5.8%.

Atik Cameras experienced a surge 
in one-off demand in respect of 
cameras for PCR machines over the 
last three years. This demand  
peaked over FY22 and reduced by 
£2.4m in FY23.  

mIKE CREEDON

Excluding this one-off business, Atik 
Camera’s revenues grew by 37%, and 
SDI’s Digital Imaging segment as 
a whole grew revenues by 16.4%. 
On a reported basis, the Digital 
Imaging segment revenues declined 
by 2.9%, with revenues at £20.9m 
and adjusted operating profit at 
£6.9m (down 19.2%). Graticules 
Optics sales were not as strong as 
in the previous year where record 
sales were achieved, however trading 
remained robust in FY23, while sales 
at Synoptics were broadly flat.

The Sensors and Control segment 
grew sales by 65.8% to £46.7m. 
Organic growth was 3.8%, and the 
remaining 62.0% growth was from 
the FY22 and FY23 acquisitions. 
Adjusted operating profit grew 
55.1% to £8.0m. 

There are eleven companies in the 
Sensors and Control division and 
several have made outstanding 
contributions to the Group this 
year. Our recent acquisitions, LTE 
Scientific (‘LTE’) and Fraser Anti-Static 
Techniques (‘FAST’), have performed 
well since joining the Group.  

Safelab Systems (acquired in March 
2022) also delivered revenues and 
profits which were higher than 
expected. Applied Thermal Control 
achieved record sales of scientific 
and industrial chillers and Sentek had 
record chemical sensor revenues. 

Monmouth Scientific was acquired 
in December 2020, when COVID-19 
was driving strong revenues and 
profits for the business. Revenue 
mix has shifted away from standard 
biological safety cabinets back 
towards more custom/modular fume 
cupboards, laminar flow cabinets and 
cleanrooms. This has necessitated a 
change in Monmouth’s logistics, as 
the number of units to commission 
at a site has declined despite overall 
sales remaining high. Furthermore, 
the business has needed more 
engineers to commission units in 
a very tough labour market. All of 
this has taken time to implement. 
Monmouth also moved to a new 
purpose-built leased facility in April 
2022, which was capitalised at a 
cost of £4.6m on balance sheet 
in accordance with IFRS 16. The 
costs of this brand-new leased site 

were higher than anticipated. The 
combination of the aforementioned 
factors has had an impact on 
Monmouth’s trading results. This 
has led to an impairment, the details 
of which are provided in the Chief 
Financial Officer’s report. 

Adjusted fully diluted earnings per 
share increased by 3.6% from 8.71p 
to 9.02p. Reported diluted earnings 
per share decreased as a result of  
the impairment of Monmouth/
Uniform intangibles by 48.8% from 
7.23p to 3.72p.

Acquisitions 

Since February 2015 we have 
acquired 17 businesses within the 
UK. Many have achieved significant 
organic growth over the years with 
SDI’s investment. An example of 
this would be Sentek, which was 
acquired in October 2015. At the 
time of acquisition, its sales were 
£2.5m and the business recorded 
profits of £0.5m. In FY23 Sentek had 
a record-breaking year, achieving 
sales of c.£5m and operating profit 
of c.£1m. As a Group employing 
a buy and build strategy, finding 
businesses with niche capabilities is 
the key to our success. SDI maintains 
its reputation as a supportive owner, 
investing in our people and facilities, 
as well as trusting the subsidiary 
management teams with their day-
to-day operations. 

However, if a subsidiary does not 
achieve long-term growth, an 
impairment of intangible assets may 
happen. Sadly, this is the case with 
Monmouth Scientific. The company 
has been profitable but not at the 
levels required to maintain the levels 
of intangible assets held on the 

Balance Sheet. We have taken steps 
to improve performance and are 
hopeful that the company can attain 
the profits levels that determined the 
original goodwill valuation.

We are pleased to have acquired two 
high-quality and profitable UK-based 
businesses over the last financial 
year, extending the technology 
within the Group as well as our 
customer base. It is expected that 
these two acquisitions will provide 
further scope for future organic 
growth and provide a base to acquire 
further businesses within these 
technology sectors.

On 1 August 2022, the Group 
announced that it had acquired 
100% of the share capital of LTE. 
Total consideration was £5.4m and 
this included £1.65m of freehold 
property and £2.6m of cash. LTE 
manufactures and services sterilizers, 
decontamination and thermal 
processing equipment, used in the life 
science and medical sectors. LTE fits 
within SDI’s target acquisition profile: 
complementary technology and 
products with capable management 

teams in place and ability to grow 
under SDI ownership. LTE is based in 
Greenfield, Oldham.

On 22 October 2022, the Group 
announced the acquisition of FAST 
for £16.9m. This included £1.76m of 
freehold property and £4.1m of cash 
immediately prior to the acquisition (at 
time of acquisition this being £1.0m of 
cash and £3.1m loaned to SDI Group). 
FAST is one of the world’s leading 
static control and generation solutions 
to OEMs, end users and distributors 
of machinery and materials around 
the world. The business is based in 
Bampton, Devon with sales offices 
in Germany and China. One of the 
positive aspects of this acquisition is 
that it gives SDI a base in China that 
could provide an opportunity for our 
other subsidiary brands to expand into 
this particular market.

We have funded both acquisitions 
from our existing cash resources 
and from our revolving credit facility 
with HSBC UK Bank. The acquired 
companies contributed £11.2m of 
revenues to the Group this year and 
both acquisitions have been earnings 
enhancing to the Group in FY23.

Operations

As the number of manufacturing 
businesses increases within the 
Group, the opportunity for synergies 
is developing across several business 
units. It has been encouraging to 
see lines of communication opening 
between our laboratory products 
businesses; Safelab Systems, 
Monmouth Scientific, LTE and 
Synoptics in particular. We have seen 
them consolidate product lines into 
a single SDI Group tender, giving 
the target customer a full turnkey 
solution. We would look for this to 
continue in future years.

As in previous years SDI has 
continued to invest in the 
improvement of its current product 
range, as well as developing new 
products and technologies. We 
are also looking to improve our 
manufacturing facilities to increase 
capacity but also to provide a better 
service to our customers.

We have invested in the acquisition 
of a CNC milling machine for 
the Atik facility in Lisbon. A CNC 
machine supports rapid turnaround 
of prototypes. The machine has 

several other uses. It de-risks our 
supply chain as it provides cover for 
a particular single source Portuguese 
supplier, and it can be used for 
low volume production to cover 
gaps when we have issues with 
other suppliers. We will also use the 
machine to produce simple, low 
volume parts that can be expensive to 
buy externally, without disturbing the 
flow of the main site operations.

Other investments include laser 
etching machines for each of MPB 
Industries, Scientific Vacuum Systems 
and Graticules Optics. These can 
be used in many applications but 
Scientific Vacuum Systems, as a 
recent example, have added QR 
codes to each part (of which there 
were many thousand items) within a 
sputter coater for a premium brand 
razor blade manufacturer to enable 
the customer to purchase spare parts 
via an easily accessible format.

Our rolling programme of upgrading 
manufacturing facilities across 
the Group continues with the 
refurbishment of the Graticules 
Optics factory in Tonbridge, which 
started in 2021 and is nearing 

completion. Sentek increased 
capacity by building a mezzanine 
floor and creating a new room for 
engineering. These investments will 
bring a capacity increase as well as 
improving efficiency, staff comfort, 
product quality and image.

We have also created a forum for 
marketing teams to share best 
practice. Initiatives include more 
effective social media usage and the 
use of artificial intelligence.

As we mentioned at the half year, in-
person trade fairs and exhibitions have 
re-started in FY23 and several of our 
businesses have attended them, with 
positive feedback received. Examples 
include ACHEMA (Berlin), Analytica 
(Frankfurt) and VISION (Stuttgart). 
Direct face to face meetings with 
customers, an effective method 
of launching new products, have 
become routine once again.

The economic backdrop does 
remain a concern. There is a threat 
of recession in the UK and the Bank 
of England has been raising interest 
rates continuously over recent 
months to try and tame inflation. 
We have not seen a high interest 
rate environment for some time and 
SDI will experience higher interest 
charges on its debt. Inflation will also 
remain a concern. However, SDI 
has started the FY24 financial year 
well and we are confident that we 
can continue to trade profitably and 
generate free cash flow over  
the coming financial year.

Mike Creedon
Chief Executive Officer 
7 August 2023

Whilst staff turnover generally remains 
low, we continue to experience a tight 
labour market. We have managed to 
fill most, but not all, skilled vacancies 
relatively quickly. Cost increases, in 
relation to materials, have generally 
been passed on to customers.

Trading Outlook

Our businesses are currently 
performing well and SDI continues 
to invest to support organic growth. 
We expect to deliver FY24 revenues 
and profits in line with market 
expectations. 

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. Supply 
chain delays were prevalent in the first 
half of FY23. These still exist but have 
eased somewhat in recent months.

The market for acquisitions appears 
buoyant, and SDI expects to acquire 
additional businesses in the FY24 
financial year.

for the year ended 30 April 2023

Ken Ford
Jon Abell

SDI Group revenues 
increased by 36.0%, from 
£49.7m in FY22 to £67.6m 
in FY23. The two new 
acquisitions in the year, 
Fraser Anti-Static Techniques 
(‘FAST’) and LTE Scientific 
(‘LTE’), together with the 
prior year acquisitions, 
Scientific Vacuum Systems 
and Safelab Systems (prior to 
the acquisition anniversaries) 
contributed £17.5m in 
additional turnover.

Revenue and Profits

From the outset of the COVID-19 
pandemic in FY21, our Atik Cameras 
business received substantial orders 
from one customer for cameras 
designed into an OEM’s PCR 
equipment. Revenues in FY23 relating 
to this represented £8.5m (FY22: 
£10.9m). Excluding this ‘one-off’ 
business, organic revenue growth 
was 6.4% on a constant currency 
basis; 7.2% in absolute terms (£2.8m). 
Encouragingly, Atik Camera’s business 
grew organically by 37% when this 
‘one-off’ business is excluded.

Gross profit increased to £42.8m 
(FY22: £31.7m) whilst margin was 
marginally down to 63.3% (FY22: 
63.8%) with the acquisitions having 
slightly lower gross margins than the 
Group average. On a like-for-like basis 
(including prior year acquisitions from 
the anniversary of the acquisition), 
gross margins increased compared 
to FY22, which was pleasing. 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 and marketing activity. 

Adjusted operating profit improved 
to £12.8m (FY22: £12.1m) being 
operating profit before the 
impairment charge, share-based 
payments, acquisition costs, 
reorganisation costs (in FY22 only), 
and amortisation of acquired 
intangible assets, an increase of 5.8%. 

Reported operating profit reduced  
to £6.8m (FY22: £10.2m) because of 
the gross impairment charge of  
£3.5m against the Monmouth and 
Uniform CGU (see below) and a  
£0.7m increase in amortisation of 
intangible assets relating to the four 
most recent acquisitions.

Impairment

SDI acquired Monmouth Scientific 
Limited (‘Monmouth’) and Uniform 
Engineering (‘Uniform’) in December 
2020 and January 2021 respectively. 
These two companies work very 
closely together and are regarded as 
one cash generating unit.  
Accounting standards require 
companies to evaluate annually 
whether the future cash flows (‘value 
in use’) exceed the value of acquired 
goodwill, intangible and other fixed 
assets and working capital. 

SDI Group plc 
Governance Report 2023 

19

prepared on a pre IFRS 16 basis, 
the impairment would have been 
approximately £1m less.

The £3.5m gross impairment 
includes the entire Monmouth 
goodwill balance of £3.0m and all 
the Uniform goodwill of £0.2m. The 
balance represents an impairment 
of £0.1m of Uniform and £0.2m of 
Monmouth customer relationships 
respectively. At the year end, 
Monmouth retains £1.6m of 
customer relationships/trade names 
as intangible assets. Uniform has no 
intangible assets remaining. 

Uniform is a key service provider 
to Monmouth, and also sells to 
Safelab Systems. In FY23, c.50% of 
Uniform’s sales were to Monmouth 
and Safelab Systems, with the 
remainder of sales external to the 
Group. Monmouth and Uniform 
on a combined basis, as a single 
cash generating unit (‘CGU’) have 
been profitable within the Group 
since acquisition and are forecast 
to continue to be profitable in FY24 
and beyond.

Monmouth’s performance in 
FY23 was impacted by the factors 
described in the Chief Executive 
Officer’s report including the annual 
costs relating to the purpose-
built facility which started from 
March 2022. The impairment 
review calculation has also been 
affected by the current higher 
interest rate environment increasing 
the weighted cost of capital in 
the calculation. Therefore, we 
have impaired a total of £3.5m 
of Monmouth and Uniform’s 
goodwill and intangible assets. 
The impairment review calculation 
includes the costs of Monmouth’s 
premises prepared on an IFRS 16 
basis; had the calculation been

SDI Group plc 
Strategic Report 2023

Chief Financial Officer’s Report continued 

Interest Payable

Interest charges for the year 
increased to £1.0m (FY22: £0.3m). 
This increase was due to the higher 
levels of debt through the year as  
well as rising interest rates.

Taxation

The taxation charge for the year was 
£1.9m (FY22: £2.3m) representing a 
tax effective rate of 33.2% compared 
to 23.7% in FY22. The tax effective rate 
for both FY23 and FY22 include one-
off factors which will not repeated: 
the impairment of intangibles not 
being deductible for tax purposes 
in FY23 and the inclusion last year 
of a deferred tax adjustment to 
align certain deferred tax assets and 
liabilities to 25%. Excluding these  
one-off adjustments results in an 
effective rate of tax of 20.7% (FY22: 
16.3%). The Group continues to 
benefit from R&D tax credits.

Earnings per Share

Adjusted diluted EPS, an alternative 
performance measure which 
excludes certain non-cash and 
non-recurring expenses was 9.02p 
(FY22: 8.71p), an increase of 3.6%. 
As a result of the impairment charge 
noted above, the diluted earnings 
per share for the Group reduced to 
3.72p (FY22: 7.23p).

Intangible Assets  
(excluding R&D)

Intangible assets increased by a net 
£5.3m from £36.0m to £41.3m at 
the end of FY23. Gross intangible 
assets (excluding R&D) grew by 
£10.8m with the two acquisitions in 
FY23 contributing to £10.5m of the 
increase. £1.8m of amortisation was 
charged in the period (FY22: £1.1m) 
against customer relationships, trade 
names and other intangible assets 
as well as the impairment charge of 
£3.5m noted above.

The £10.5m in increased intangible 
cost was split as follows: £1.4m 
relates to LTE and £9.1m to the 
acquisition of FAST. Goodwill rose 
by £5.5m before the impairment 
charge: LTE contributed £0.7m and 
FAST £4.8m. Customer relationships, 
trade names and other intangibles 
cost increased by £5.0m before the 
impairment charge: LTE represented 
£0.7m and FAST £4.3m.

Investment in R&D

Under IFRS we are required to 
capitalise certain development 
expenditure, and in the year ended 
30 April 2023, £0.3m (FY22: £0.4m) 
of cost was capitalised. Much of 
the work of our R&D teams does 
not qualify for capitalisation and 
is charged directly to expense. 
Amortisation for 2023 was £0.5m 
(FY22: £0.4m). The carrying value  
of the capitalised development at  
30 April 2023 was £0.7m (FY22: 
£0.9m) to be amortised over 3 years.

Cash Flow and Working 
Capital

Cash generated from operations 
reduced to £10.9m (FY22: £14.7m). 
The reduction was due to a £2.9m 
build-up of inventories and a £3.5m 
reduction in customer advances, 
offset by a £2.7m reduction in 
debtors. £2.1m of the inventory 
build-up was to mitigate against the 
impact of component shortages 
and the balance related to Scientific 
Vacuum Services building a 
sputtering machine for a large 
OEM customer, which will become 
revenues in FY24. The £3.5m 
reduction in customer advances was 
due to £2.7m in COVID related cash 
flow at Atik received in prior years 
and £0.8m from a pre-acquisition 
advance at LTE. 

Taxes paid have increased to £2.2m 
(FY22: £1.3m). This included £0.4m  
of FY22 tax relating to acquisitions. 

Our investment in fixed assets 
totalled £1.1m (FY22: £1.4m) which 
included investments in machinery  
at Atik Cameras.

Acquisition of new businesses 
remains our largest cash outlay, with 
£18.7m deployed on a cash-free 
basis (FY22: £11.0m of which £0.2m 
was in shares). A further £2.4m 
was paid in relation to prior period 
deferred consideration. At the end 
of the year contingent consideration 
of £1.0m was outstanding (FY22: 
£3.4m) relating to the acquisition of 
SVS, which is to be settled over FY24 
pending assessment of the relevant 
earn-out conditions.

Funding

The Group acquired two businesses 
over the period, funded through 
additional debt.

Net debt (excluding lease liabilities), 
or bank debt less cash, was £13.3m 
at the end of the year, compared to a 
net cash position at the beginning of 
the year of £1.1m. This represents a 
net debt: EBITDA ratio of 0.9x, which 
is well within the ceiling provided by 
our bank facility. On 30 November 
2022, the Group reached agreement 
with HSBC to exercise £5m of an 
available £10m accordion option, 
which increased the committed 
loan facility from £20m to £25m. 
The balance of the accordion option 
(£5m) remains available to the Group 
(at the discretion of HSBC) for future 

exercise. In March 2023, HSBC approved 
an extension of the repayment date 
by one year to November 2025. The 
revolving credit facility can be extended 
for a further year at HSBC’s discretion.  
At the end of the financial year the 
Group had drawn down £16m of its 
revolving credit facility (FY22: £4m), 
leaving £9m in headroom (excluding the 
additional £5 million accordion option).

The Group has an unstretched balance 
sheet and has sufficient access to funds, 
alongside its steady cash flow, to acquire 
new companies and invest in our current 
portfolio of businesses.

SDI Group plc 
Strategic Report 2023

Strategy 

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 seven 
years has been good, with seventeen 
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. The 
ability to generate synergies has 
increased as the Group has grown in 
scale and SDI has acquired businesses 
in closely related segments.

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.

order pipeline, revenue, gross 
profit, costs, adjusted operating 
profit, and free cash flow.

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.

Additionally, the Board reserves 
specific agenda items for discussion 
of environment, social and 
governance matters, health and 
safety and other employee  
welfare-related issues.

SDI Group plc 
Strategic Report 2023

Section 172(1) Report

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.

SDI Group plc 
Strategic Report 2023 

25

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. 
Staff in our operating businesses are 
also interested and informed about 
the activities and performance of the 
wider Group.

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.

We have recently adopted several 
policies which should enhance the 
governance around our supply chain. 
A Group Modern Slavery policy has 
been approved alongside a Child 
and Forced Labour policy. The 
geographic split of our supply chain 
suggests that the risk profile for such 
issues is low, but we consider this 
a positive step which will improve 
engagement with our suppliers. 

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

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.

Environmental, Social & Governance

Maximising Positive Impact 

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.

SDI Group plc 
Strategic Report 2023 

27

SDI Group recognises that the 
significant environmental challenges 
facing the world, including man-
made climate change, deforestation 
and habitat loss, and freshwater 
depletion, 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 externalities of 
our operations.

SDI’s current businesses have 
only minimal direct impacts on 
the environment, as they are not 
involved in heavily polluting industries. 
Furthermore, 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 negative impacts, 
maximise positive impacts, and 
innovate solutions to challenges 
take place within our businesses. 
These organisations 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.

FY23 Progress

We consider that a thorough 
understanding of our current ESG 
position is a critical first step towards 
making and quantifying progress over 
the coming years. As a result, we have 
completed a benchmarking/gap 

analysis exercise with our thirteen 
trading companies that currently 
comprise the Group. This exercise 
uncovered a number of areas that SDI 
Group companies already excel in, as 
well as areas in which there is room 
for improvement. 

The Group has already made 
significant strides towards social 
sustainability, with robust terms of 
employment and systems in place 
that protect employees’ rights 
and promote their wellbeing. The 
Group is, however, at the start of its 
journey in terms of several areas of 
environmental sustainability, such as 
quantifying and reducing greenhouse 
gas emissions. The operations of 
SDI Group’s are unlikely to pose 
significant threats to the environment, 
but we understand the need for 
further analysis to better understand 
and mitigate environmental impacts 
where they do arise. 

FY24 Plan

This year, we are undertaking an 
ambitious program of sustainability 
initiatives. For the first time, we will 
be quantifying the carbon footprints 
(Scopes 1, 2, and key categories of 3) 
for all Group companies. We will  
start with collecting data for FY23  
and then will look to extend the 
scope and quality of our data 
collection processes for FY24.

Using this baseline, we will perform 
scenario modelling to analyse 
different potential pathways to  
reduce our emissions and consider 
various policies that will enable us  
to reach reduction targets. The 
outputs of these efforts will feed  
into the creation of a robust longer-
term strategy.

We will compile an action plan to 
enable us to meet our emissions 
reduction goals and continue to 
engage and support all subsidiary 
companies on their ESG journey. 

We will close out FY24 with another 
ESG screening exercise, aiming to 
measure progress to date and set 
further targets in line with an ever-
increasing level of ambition. 

We have formalised key policies in 
the realms of ethical conduct and 
social/environmental sustainability, 
including policies addressing 
modern slavery; diversity, equity, 
and inclusion; and child labour. SDI 
Group has, naturally, always acted in 
an ethical manner and complied with 
all relevant legislation, with ethics 
policies and environmental/social 
safeguards in place since the Group’s 
inception. The standardisation 
and expansion of these policies at 
Group level is intended to streamline 
Group processes for addressing 
these concerns and underscore our 
continuing commitment to ethical 
conduct. 

People

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.

Naturally, we comply with all  
relevant legislation, including:

l  Health and safety regulation. 
The Board reviews monthly 
reports from all of its businesses  
to ensure root causes of any  
issues are addressed (see our 
Health and Safety policy on the 
following page).

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 Group 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, fairly 
and encourage them to apply 
these principles themselves. We 
are committed to paying a fair 
wage for their work. 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. To reinforce our 
existing policies, we have recently 
approved a separate Diversity, 
Equity and Inclusion policy and an 
Ethics policy (see right). 

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 (see DEI section right).

l  Modern slavery and human 

trafficking. The Group has recently 
adopted a Child and Forced 
Labour policy and a Group Modern 
Slavery policy. Whilst the individual 
members of the Group are not 
within the scope of the Modern 
Slavery Act, we are committed 
to identifying Modern Slavery 
risks across our supply chain, 
which include slavery, human 
trafficking, child labour and forced/
compulsory labour and to ensure 
that there is no Modern Slavery 
within its principal supply chains.

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.

Diversity, Equity and Inclusion (DEI)
To strengthen our commitment to 
equal opportunities, we have recently 
approved a separate DEI policy. This 
policy commits SDI to the elimination 
of unlawful and unfair discrimination 
and values the differences that diversity 
brings. The Group will not discriminate 
because of age; disability; gender; 
marital status; pregnancy; race  
religion; sex; sexual orientation. 

This policy applies equally to the 
treatment of any third party who 
interacts with SDI Group Plc.

SDI values the diverse nature of 
people, and the Group has a zero 
tolerance policy on harassment and 
discrimination. We all have a duty to 
act in accordance with this policy  
and treat colleagues with dignity at 
all times. We will not tolerate 
discriminatory practices or behaviours.

We will undertake an exercise to 
collect data over the next twelve 
months to enable us to report some 
further statistics to illustrate the 
diversity of our workforce.

Ethics policy
Whilst equal opportunities have been 
long been part of the Group ethos (and 
included within our staff handbook), 
we have approved a separate ethics 
policy which expects all employees 
and third parties acting for and on 
behalf of our Group to observe the 
highest standards of ethics, integrity 
and self-respect at all times and for 
the duration of their relationship with/
employment by the Group.

We have considered our values, for 
the first time, this year. It is expected 
that these will be developed further 
over the forthcoming year.

Health and safety 
Health and safety is of high 
importance to the Group and a key 
priority for our management teams. 
Our employees must be and feel 
safe at work and we therefore aim 
to provide a safe and comfortable 
working environment for them. The 
Group encourages all of its subsidiary 
companies to seek continuous 
improvement and promote a strong 
health and safety culture. 

The Group routinely monitors 
health and safety adherence across 
our businesses. As we operate a 
decentralised structure, performance 
is monitored at a Group level with 
each trading subsidiary directly 
responsible for compliance with local 
health and safety regulations. We 
have also instituted a Group-wide 
regular independent health and safety 
review, which assesses compliance 
and provides local management with 
feedback to continually improve 
health and safety. 

Planet

Individual companies have 
made efforts to minimise their 
consumption of natural resources. 
For example, Atik Cameras in 
Portugal and Monmouth Scientific 
have installed solar panels to reduce 
their energy demands. A number of 
businesses, such as Graticules, Atik 
Cameras (Portugal) and Monmouth 
already recycle 80% or more of 
their waste. Astles, Atik Cameras 
(Portugal), Graticules and Scientific 
Vacuum Systems, have all sourced 
over 40% of their energy from 
renewable sources.

and improve patient safety. This, in 
turn, contributes to advancements 
in scientific development, medical 
treatments and procedures.

Sentek produce a number of different 
types of sensors. Products supplied 
into the medical industry are integral 
for routine blood analysis work and 
assist in diagnostics, supporting patient 
care day to day. Other sensors are 
used in identifying changes in water 
quality to help provide clean, fresh 
drinking water to households. Sentek’s 
products also support pharmaceutical 
companies as they develop drugs to 
improve people’s lives.

MPB Industries manufacture a 
range of variable area flowmeters for 
liquid and gas applications. MPB’s 
flowmeters are used in human and 
veterinary medical anaesthesia, water 
treatment to ensure safe drinking 
water for communities, as well as 
pollution/air quality measurement.

Governance

The Board has set official goals 
around developing the Group’s ESG 
strategy and refining relevant targets 
and this was reflected in the personal 
objectives given to the executive 
directors. The Board has been kept up 
to date monthly over FY23 as we have 
made progress in developing the ESG 
agenda. Over FY24, it is to become 
a quarterly standing agenda item 
to ensure continued focus on and 
commitment to sustainability. 

The Group will additionally include 
ESG considerations as a key part of our 
annual strategic planning processes. 

Several businesses monitor non-GHG 
emissions as a routine, including 
SVS, Safelab Systems, Graticules and 
Monmouth. We have proactively 
investigated our businesses’ 
proximity to ecological protection 
areas and found no risk of potential 
encroachment.

Many SDI businesses make products 
that have a positive impact for the 
environment and society. 

Monmouth Scientific’s products 
include fume cupboards which are 
focused on the recirculation of air in a 
laboratory by using activated carbon 
and HEPA filters. These products have 
low energy demands when compared 
to traditional fume extraction systems, 
which often extract pollutants into the 
atmosphere and necessitate greater 
temperature control measures as 
heating/cooling is lost to the outside.

Applied Thermal manufactures and 
supplies a range of chillers, coolers 
and heat exchangers used within the 
scientific instrument support market. 
Their products have been used to help 
develop and manufacture vaccines 
during COVID-19 and are included 
in MRI machines and equipment that 
is used for cancer therapy. Applied 
Thermal’s products reduce water 
consumption, and the company is 
developing a range of chillers that use 
refrigerants with much lower global 
warming potential than conventional 
alternatives. Applied Thermal’s chillers 
are already designed to a very high 
standard and do not leak refrigerants. 

Safelab Systems produce fume 
cupboards that provide a safe 
environment for lab users. Their 
products can reduce GHGs via the 
use of filtered fume cupboards, 
which recirculate the air back into the 
room. This also reduces the volume 
of air ducted out to the atmosphere, 
reducing the amount of energy needed 
to air condition the interior spaces. 

Atik Cameras has produced a high 
volume of specialist cameras over 
recent years that were used in PCR 
machines. These products were in 
the vanguard of the battle against 
COVID-19, particularly in China. 
Atik produces a variety of specialist 
cameras that are used in different 
applications such as sky surveillance 
equipment to look for sky objects/
debris and predicting weather. One 
particular range of cameras are 
included within gel-doc machines 
used in medicine and other life 
science related research.

Synoptics, based in Cambridge, has a 
Synbiosis division which designs and 
manufactures instrumentation for 
the Microbiology sector, which allow 
scientists to rapidly count bacteria to 
speed up the quality control process 
in the food and pharma sectors. 
The equipment can also be used to 
measure zones of inhibition which is 
essential in vaccine production. 

The company’s Syngene division 
designs and manufactures molecular 
imaging equipment (gel-doc 
machines) that advances molecular 
science in vaccine research, health 
and the pharmaceutical sector.

The company’s Fistreem division 
designs and manufactures 
instrumentation for water distillation. 
These systems can be used in all 
industries and cuts down the use of 
single-use plastics by distilling water 
on demand.

LTE Scientific produce a range 
of autoclave ovens, which play 
a crucial role in healthcare and 
medical research by providing a 
reliable method of sterilisation by 
effectively killing microorganisms and 
pathogens. LTE’s products are used 
in hospitals, research laboratories, 
clinics, and dental surgeries to sterilize 
instruments and supplies. Autoclaves 
help in areas of scientific research, 
prevent the spread of infections

Principal Risks & Uncertainties

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

Risk status: Unchanged

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

Risk status: Unchanged

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

Risk status: Unchanged

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

Risk status: Unchanged

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 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. We have also invested in 
software which aids procurement of 
electronic parts globally.

Recruitment and Staffing

Risk status: Unchanged

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

Risk status: Reduced

The effects of COVID-19 have 
reduced over the last year but not 
completely gone away. There  
have been instances of COVID  
outbreaks disrupting operations, 
requiring re-instatement of social 
distancing protocols. 

The Group remains alert to 
continuing risks.

Currency and Foreign 
Exchange

Risk status: Unchanged

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 not historically 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.

Cyber

Risk status: Increased

This risk is included for the first time. 
The risk of cyber-attacks has increased 
in recent times.

Group and operating business 
management depend critically on 
timely and reliable information from 
their IT systems to run their businesses 
and serve their customers’ needs.

If an internal failure or external attack 
occurs there is a potential for a loss of 
digital intellectual property/data and/
or the ability to operate systems. The 
resultant loss of information or the 
ability to continue operations may lead 
to financial and reputational damage. 

The decentralised nature of the Group, 
including stand-alone IT systems for 
each business, limits the potential 
impact to any individual business and 
minimises cross-contamination risk. 
There is good support and back-up 
built into local IT systems.

The Group has also conducted a 
detailed review of the robustness 
of cyber security measures for both 
existing businesses and acquisitions 
which has resulted in investment in 
more robust systems and procedures. 

Inflation risk

Risk status: Increased

This risk is included for the first 
time. Significant or unexpected 
cost increases by suppliers due 
to the pass through of higher 
commodity prices or other price 
increases, higher trade tariffs and/or 
foreign currency fluctuations, could 
adversely impact profits if businesses 
are unable to pass on such cost 
increases to customers.

A number of characteristics of the 
Group’s businesses moderate the 
impact of this. SDI has a variety of 
businesses which operate in different 
sectors with different characteristics 
and across several geographic 
markets. Many businesses offer 
specialised products and services, 
which are often specific to their 
application, increasing customers’ 
switching costs. Our businesses are 
often agile, able to redesign to take 
cost out of the supply chain to help 
maintain margin. 

Group management remain alert to 
the ongoing nature of this risk.

Liquidity

Risk status: Unchanged

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

Corporate Governance Statement

Chairman’s Introduction

As Chairman I am responsible for the leadership of the Board and for ensuring the Board’s effectiveness. I also have the 
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.

1  

A strategy and business 
model which promotes 
long-term value for 
shareholders

2 

Understanding and 
meeting shareholder 
needs and expectations

3 

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

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.

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. 

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.

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 three 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 board and committee meetings during the 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.

Our directors have been chosen because of the skills and experience they 
offer. Of our six directors one is female and five are male. All have listed 
company experience and one was the CEO of an investment bank, one  
was a COO of a listed business, one has significant marketing and 
commercial experience and three are accountants.

Biographies of the 
Directors are presented 
on pages 32-33 in this

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

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.

The Board

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 (page 35) operate within clearly defined terms of reference, and 
which report back to the Board.

We have set out in section 2 (page 34) how we maintain a regular dialogue  
with our shareholders including welcoming all shareholders to our AGMs.

The Board comprises the Chairman, two Executive Directors and three 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 43 and a statement on going concern  
is given on page 45.

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 David Tilston and has Andrew Hosty and Louise Early as other members,  
meets not less than twice annually and more frequently if required. 

The Board considers that David Tilston has 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.

A report of the Audit Committee is provided on page 39.

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. The Nomination Committee was involved in the recruitment 
of Andrew Hosty and Louise Early, our recently appointed non-executive directors, over the last financial year. It also met 
to recruit a new Chief Financial Officer to replace Jon Abell, who retired in 2022. 

The Nomination Committee continued to assist the Chairman with the board evaluation process as set out in Principle 7 
of our Governance Statement above.

Conformance with Best Practice

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

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

– Ken Ford has retired from the Remuneration Committee; 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.

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

I am pleased to present the Audit 
Committee report for the year 
ended 30 April 2023. 

Composition of the 
Committee 

The Committee consists of myself 
(as Chairman), Andrew Hosty 
and Louise Early. 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 am Audit Committee 
Chairman of two other AIM-listed 
companies. 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 will 
complete a self-assessment exercise 
on its effectiveness using externally 
sourced material after the Annual 
Report has been signed.

Responsibilities 

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;

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.

Audit Process 

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, impairment charges 
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 34-38 
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 as it continues to evolve 
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 FC 
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.

Report of the Remuneration Committee

Directors’ Remuneration Report

Remuneration Committee

On behalf of the Board, I am 
pleased to present the report of the 
Remuneration Committee for the 
year ended 30 April 2023.

The Committee is chaired by myself 
and has David Tilston and Louise Early 
as its other members. 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. In 2023 we met 5 
times, 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 
is simple and straightforward so 
that there is a clear link between 
Group performance and executive 
remuneration.

My predecessor as Remuneration 
Committee chair undertook a 
benchmarking exercise to consider 
executive compensation. A third-
party specialist consultancy was 
retained to assess the remuneration 
package for the Chief Executive 
and to consider the package to 
offer potential CFO candidates. 
The purpose of the exercise was to 
enable the company to retain and 
attract the best quality executives 
to support SDI as it continues 
to grow. In addition, executive 
compensation decisions were 
informed by feedback received 
during the recruitment of our new 
CFO. As a result of all this, several 
changes were made, including an 
increased to basic salaries, and these 
are outlined below.

The revised remuneration packages 
covered the following elements: 

l  Base salary: the Remuneration 

Committee updated the executive 
directors 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 
was increased to (and capped) 
at 100% of the individual’s salary 
(previously 50%); 

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. This has increased  
from 50% to 100% of salary. 

l  Equity: share options awarded as 

appropriate; and 

l  Group or cash 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. 

The details of the awards already 
made under the LTIP scheme are set 
out in the Remuneration Report on 
page 42.

Remuneration of Chairman 
and Non-Executive Directors 

The fees paid to the non-executive 
directors are determined by the 
Board. The Chairman has historically 
participated in the Group’s LTIP 
scheme however this is no longer 
the case. 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, March 2020 and in October 2021.

An award was made on 25 October 2022 with performance conditions based for 50% on the growth in fully diluted 
Earnings Per Share in the three years starting 1 May 2022 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:

On 19 March 2023, 96% of the options awarded under the scheme in March 2020 vested and the remaining 4% had 
lapsed as they related to a director who had left during the period.

The above table is a subset of the share option table on the previous page.

The market price of the company’s shares at the end of the financial year was 176p and ranged from 144p to 200p  
during the year. The exercise price of the ordinary options ranges from £0.172 to £1.740, and of LTIP options is £0.010.

In March 2023, the Remuneration Committee reviewed and made minor updates to the rules of the 2018 LTIP Scheme  
to further align them to best and market practice where relevant.

Directors’ Responsibilities Statement

The directors are responsible for preparing the Annual Report comprising Directors’ Report, 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 the consolidated financial statements in accordance with UK adopted international accounting standards 
and with those parts of the Companies Act 2006 applicable to companies reporting under IFRS 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 and profit or loss of the Company and 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 UK adopted international accounting standards and with those parts of the Companies 

Act 2006 applicable to companies reporting under IFRS for the parent company have been followed, subject to any 
material departures disclosed and explained in the financial statements

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

will continue in business.

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the 
company’s transactions and disclose with reasonable accuracy at any time the financial position of the company and 
enable them to ensure that the financial statements and the Directors’ Remuneration report comply with the Companies 
Act 2006 and Article 4 of the IAS Regulation. They are also responsible for safeguarding the assets of the company and 
hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

The directors confirm that:

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

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 preparing the annual report in accordance with applicable law and regulations. Having 
taken advice from the Audit Committee, the directors consider the annual report and the financial statements, taken as a 
whole, provides the information necessary to assess the company’s performance, business model and strategy and is fair, 
balanced and understandable. 

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

To the best of our knowledge:

l  the group financial statements, prepared in accordance with UK adopted international accounting standards and with 
those parts of the Companies Act 2006 applicable to companies reporting under IFRS, give a true and fair view of the 
assets, liabilities, financial position and profit or loss of the group and the undertakings included in the consolidation 
taken as a whole; and 

l  the group financial statements, prepared in accordance with United Kingdom Generally Accepted Accounting Practice 

give a true and fair view of the assets, liabilities, financial position and profit or loss of the parent company; and 

l  the Strategic Report and Directors’ Report include a fair review of the development and performance of the business 

and the position of the company and the undertakings included in the consolidation taken as a whole, together with a 
description of the principal risks and uncertainties that they face.

All KPIs and risks are disclosed in the Strategic Report on page 23 and 30-31. 

The Board does not recommend the payment of a dividend. 

Directors

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

K Ford

The interests of the directors and their families in the share capital of the Company are shown in the directors’ 
remuneration report on pages 41-42.

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 2022, the directors were given the power to:

l  Arrange for the Company to purchase its own shares in the market up to a limit of approximately 10% of its issued 

share capital;

l  Allot ordinary shares up to an aggregate nominal value of £340,000;

We have reviewed the latest Pre-Emption Group Statement of Principles 2022 in preparation of the forthcoming AGM 
expected to be held on 29 September 2023.

 In line with the latest Statement of Principles, the directors will be seeking shareholder approval to:

 l Arrange for the Company to purchase its own shares in the market up to a limit of approximately 10% of its issued 

share capital;

l  Allot ordinary shares and disapply the statutory pre-emption rights in accordance with the latest Investment 

Association Share Capital Management Guidelines published in February 2023 and Pre-Emption Group Statement  
of Principles.

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 62-65.

The Group ended FY23 with net debt of £13.3m compared to a net cash position of £1.1m as at 30 April 2022 and 
generated free cash flow (before acquisition consideration) of £6.4m. Free cash flow was lower than FY22 due to a £3.5m 
unwind of previous customer advances received and a £2.9m increase in inventories, £0.8m of which was for Scientific 
Vacuum Services to build a sputtering machine for a customer and the rest to mitigate against component shortages. This 
was offset by a £2.7m reduction in debtors. On 30 November 2022, the Group reached agreement with HSBC to exercise 
£5m of an available £10m accordion option, which increased the committed loan facility from £20m to £25m. £16m 
was drawn down under this facility at the year-end (see note 22). In March 2023, HSBC approved an extension of the 
repayment date by one year to November 2025. This provides the Group with greater certainty over long-term liquidity. 

The Board has considered the potential of a downturn given the current economic environment. The Group is in a strong 
financial position with available facilities, sufficient headroom on all covenants associated with the revolving credit facility, 
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, evaluated 
a severe downside scenario and performed a sensitivity analysis, all of which the Board considers extremely unlikely. In 
the event of a more severe scenario (without applying any mitigations), only the interest cover covenant would come 
under stress. However, mitigations would be obviously applied should this unlikely scenario present itself, such as (but not 
restricted to) further cost cutting, sale and leaseback of freehold property and potential disposal of assets. This 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. 65 employees were 
employed for development activities in the year (2022: 51).

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

shareholdings, up to an aggregate nominal value of £51,100.

Future Development

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

SDI Group plc 
Report of the Independent Auditor

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

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 2023, which comprise the consolidated income statement and 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 notes to the 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 2023 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.

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 30 April 2025, assessing 
how these forecasts were compiled and assessing 
their appropriateness by applying sensitivities to the 
underlying assumptions, which we also challenged; 

l  obtaining management’s downside scenario, which 
reflects management’s assessment of uncertainty 
and the mitigating actions in place, and evaluating 
the assumptions regarding reduced trading levels 
under this scenario;

SDI Group plc 
Report of the Independent Auditor

disclosures and analysed how those risks might affect  
the Group’s and the parent company’s financial  
resources or ability to continue operations over the  
going concern period. 

In auditing the financial statements, we have concluded 
that the directors’ use of the going concern basis of 
accounting in the preparation of the financial  
statements is appropriate. 

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

Our responsibilities and the responsibilities of the  
directors with respect to going concern are described  
in the relevant sections of this report.

l  obtaining management’s reverse stress test, which 

reflects management’s assessment of an implausible 
scenario of how the base case scenario can be broken, 
which would result in a material uncertainty related to 
going concern, and assessing whether this represents an 
implausible scenario; 

l  evaluating the accuracy of management’s historical 
forecasting and the impact of this on management’s 
assessment; and

l  assessing the appropriateness of disclosures in respect 
of going concern made in the financial statements.

In our evaluation of the directors’ conclusions, we 
considered the inherent risks associated with the Group’s 
and the parent company’s business model including 
effects arising from macro-economic uncertainties such 
as the crisis in Ukraine and inflationary environment in 
the UK, we assessed and challenged the reasonableness 
of estimates made by the directors and the related

Our auditor’s report for the year ended 30 April 2022 included no key audit 
matters that have not been reported as key audit matters in our current  
year’s report.

We performed an audit of the financial information of components using component materiality (full-scope audits) of 
the financial statements of the parent Company, SDI Group plc, and of the financial information of five other significant 
components of the Group, and specified audit procedures on the financial information of six components (specified 
audit procedures), to gain sufficient appropriate audit information at Group level. 

This gave coverage of 77% of the Group’s revenue and 84% of the Group’s profit before tax before the impairment of 
intangible assets. All other components of the Group were selected as ‘neither significant nor material’, and analytical 
procedures were performed.

The type of work performed on components changed from prior year due to changes in the Group.

Key Audit Matter – Group

How our scope addressed the matter – Group

Occurrence of Revenue

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

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

The group has recognised revenue of £67.6m  
(2022: £49.7m) during the year, which is  
comprised of revenue from sales of goods and 
income service contracts.

The group’s revenue comprises several individually 
material streams recognised either at a point in 
time or over time in accordance with International 
Financial Reporting Standard (IFRS) 15 ‘Revenue from 
Contracts with Customers’.

The significant risk was pinpointed to:

l  transactions that did not follow the normal 
business process for certain subsidiaries;

l  a contract which was highly material to a 

subsidiary and the group; and

l  estimates involved in recognising revenue 
overtime in relation to open contracts.

Relevant Disclosures in the Annual Report 
and Accounts 2023

l  Financial statements: Note 3, Principal Accounting 

policies and Note 5, Segmental Analysis 

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

l  assessing whether the revenue recognition 

accounting policy for each type of revenue was 
consistent with IFRS 15 and checked that these 
policies were applied correctly for the revenue items 
selected for testing.

For transactions not following normal business 
processes:

l  performing audit data analytics procedures to 

identify unexpected transactions impacting the 
revenue cycle, which were then tested; and

l  testing the occurrence of revenue arising from the 
sale of goods by selecting a sample of transactions 
throughout the year and agreeing them supporting 
documentation.

For a material contract:

l  testing 100% of the transactions for the contract in 
the year, obtaining the proof of despatch, invoice 
and cash received, and assessed whether this was in 
line with the contract terms and our expectations. 

For revenue overtime with unfulfilled performance 
obligations:

l  testing the occurrence of revenue arising 

from service contracts by selecting a sample 
of transactions and agreeing the revenues to 
supporting evidence, recalculating the revenue 
recognised, and assessing the appropriateness of 
any accrued or deferred income balance at the  
year end.

Key Observations

Based on our audit work, we identified an adjustment 
to revenue of £1.5m which has been posted by 
management. The adjustment related to amendment 
to accounting for contracts from over-time to 
point in time recognition basis. No further material 
misstatements were noted in respect of revenue 
recognised in the year nor any instances of revenue 
not being recognised in accordance with the group’s 
accounting policies.

Valuation of Intangible Assets on 
Recognition of the Acquired Businesses

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

The group acquired two businesses in the year –  
LTE Scientific Limited and Fraser Anti-Static 
Techniques Limited. At 30 April 2023, the group 
recognised £10.4m of intangibles relating to the 
acquired businesses.

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

In addition, there is significant management 
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 identified 
the risk as a significant risk. 

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

l  assessing the group’s accounting for acquisitions to 

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

l  obtaining the sale purchase agreements for 

each acquisition, to ensure the completeness of 
consideration recorded by management;

l  obtaining supporting purchase price allocations, 

prepared by management or their expert to support 
the valuation of intangible assets acquired;

l  considering the competency of experts used by 
management to determine the fair value of  
intangible assets to be recognised;

l  evaluating management’s considerations as to the 
nature of the separately identified intangibles, and 
challenged whether any other intangible assets 
should have been separately identified. 

l  Evaluating the acquisition accounting documents 
prepared by management for the two acquisitions 
made in the year, and evaluating the assets 
recognised at fair value, considering if the fair value 
uplifts are appropriate.

l  recalculating the fair value of consideration paid in 
respect of both acquisitions to determine whether 
these have been accurately recorded; and

l  using an 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 assessed the appropriateness of 
discount rates and growth rates applied.

Combinations

Our Results

Based on our audit work, we did not identify any 
material misstatements in the valuation of intangible 
assets on recognition of the acquired businesses. 

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

l  obtaining and assessed the mathematical accuracy 

of management’s impairment model;

l  corroborating and challenged management’s key 
assumptions to ensure they are reasonable and in 
line with the requirements of IAS 36;

l  using an auditor’s expert to assess and challenge 

management on the appropriateness of the discount 
rate applied, by calculating an appropriate discount 
rate and applying sensitivities;

l  performing sensitivity analysis on other key 
assumptions in the impairment model; and

l  Challenging management on disclosures regarding 

goodwill impairment.

Carrying Value of Intangible Assets 
(including Goodwill) in Relation to the 
Monmouth CGU

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

In accordance with International Accounting 
Standard (IAS) 36 ‘Impairment of Assets’, an annual 
impairment review is required to be performed by 
management to determine whether the carrying 
value of goodwill and intangible assets with an 
indefinite useful life is appropriate.

The goodwill of the Monmouth CGU was determined 
to be fully impaired by management as at 30 April 
2023, resulting in an exceptional charge of £3.5m 
(2022: £nil) which included an element allocated to 
other intangible assets. 

The impairment review is performed by comparing 
the carrying value of the identified cash generating 
unit with the recoverable amount, being the higher of 
value in use or fair value less costs to sell.

Management’s assessment of the potential 
impairment incorporates significant judgements. Due 
to the inherent uncertainty, we identified the risk of 
impairment of intangible assets as a significant risk.

Our Results

Based on our audit work, we agree with 
management’s assessment that Monmouth CGU  
has been impaired based on its discounted future  
cash flows.

We did not identify any key audit matters relating to the audit of the financial statements 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:

Parent Company

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

£480,000, which is approximately 5% of the 
group’s profit before tax before exceptional 
items at the fieldwork stage of the audit. 

£312,000, which is 2% of the parent  
company’s total assets, capped at 65% of 
group materiality.

Significant 
judgements made 
by auditor in 
determining the 
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, as this is a key 
performance indicator used by the business.

l  A measurement percentage was chosen 
which reflected our knowledge of the 
business from prior year audits and aligns 
with our firm’s methodology.

l  An asset-based benchmark was 
considered the most appropriate 
benchmark because the parent company  
is a holding company and does not trade.

l  We used a measurement percentage of 

2% of total assets, which was then capped 
at 65% of group materiality.

Materiality for the current year is lower than the 
level that we determined for the year ended 
30 April 2022 to reflect the decrease in profit 
before tax before exceptional items this year.

Materiality for the current year is lower than  
the level that we determined for the year 
ended 30 April 2022 to reflect a lower cap  
due to aggregate component materialities 
reaching the firm’s permitted threshold.

Significant revisions 
to the materiality 
threshold that were 
made as the audit 
progressed.

We calculated materiality as £517,000 at 
the planning stage of the audit based on 
the estimated profit before tax. As the 
profit before tax was significantly lower at 
the fieldwork stage, we chose to re-assess 
materiality and revised our procedures 
accordingly. 

The final profit included an adjustment for an 
impairment of goodwill as described in the 
KAM section above. We chose not to revise 
our materiality once the final profit before tax 
was known and we consider the impairment 
to be an exceptional item.

We calculated materiality as £285,000 at 
the planning stage of the audit based on the 
estimated total assets. This was re-assessed 
at the fieldwork stage based on the revision 
to group profit before tax, and no change  
was required to our audit procedures. 

We chose not to revise our materiality once 
the final amount for total assets was known.

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

Significant 
judgements 
made by auditor 
in determining 
the performance 
materiality

£336,000, which is 70% of financial  
statement materiality.

£234,000, which is 75% of financial  
statement materiality.

In determining performance materiality, we 
made the following significant judgements:

identified within the parent company audit 
in the prior year.

Therefore we elected to set 75% as our 
performance materiality threshold.

Significant revisions 
of performance 
materiality threshold 
that were made as 
the audit progressed

We calculated performance materiality at the 
planning stage of the audit to be £361,000 
based on 70% of the financial statement 
materiality. Performance materiality was 
re-assessed at the fieldwork stage, based on 
the revision to financial statement materiality. 
No changes were made to the measurement 
percentage used as a result of revised figures.

We calculated performance materiality at the 
planning stage of the audit to be £213,000, 
based on 75% of planning materiality. 
Performance materiality was re-assessed at 
the fieldwork stage, based on the revision to 
financial statement materiality. No changes 
were made to the measurement percentage 
used as a result of revised figures.

Specific materiality

We determine specific materiality for one or more particular classes of transactions, account 
balances or disclosures for which misstatements of lesser amounts than materiality for the 
financial statements as a whole could reasonably be expected to influence the economic 
decisions of users taken on the basis of the financial statements.

Specific materiality

We determined a lower level of specific 
materiality for the following areas:

An Overview of the Scope of Our Audit

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

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

SDI Group plc 
Report of the Independent Auditor

57

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

l  Performance of full scope audits of the financial information of SDI Group plc, Atik Cameras Limited, Perseu Comercio 
de Equipamento Para Informatic E Astronomica SA, Fraser Anti-static Techniques Limited, LTE Scientific Limited, and 
Monmouth Scientific Limited. These full-scope audits included all of our audit work on the identified key audit matters 
as described on the previous page.

l  Specified audit procedures were performed on the financial information of the following components: Astles  

Control Systems Limited, Chell Instruments Limited, Safelab Systems Limited, Scientific Vacuum Systems Limited,   
Sentek Limited, and Applied Thermal Control Limited; 

l  Analytical procedures were performed on the financial information of all other components using group materiality;  and

l  Testing performed covered 78% of group revenue, either through full-scope or specified audit procedures, and 

84% of profit before tax.

Performance of our audit
During our audit, all procedures over the full-scope audits, specified audit procedures and analytical review, were 
performed by the group engagement team, aside from the full-scope testing of Perseu Comercio de Equipamento  
Para Informatic E Astronomica SA, which was performed using a separate engagement team consisting of staff from a 
Grant Thornton International Limited member firm.

In the current year, the group engagement team made site visits to all significant components and entities which were 
subject to specified audit procedures.

Communication with component auditors
The group engagement team communicated with one overseas component auditor, in order to perform a full-scope 
audit, throughout the stages of their work, from planning, through fieldwork and as part of the concluding procedures.

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

and IT general controls, and assessed the risks of material misstatement at the group level; 

Changes in approach from previous period
Due to changes in the group, including acquisitions in the year, the type of work performed at components changed.

l  All financial reporting is based in the UK, other than for Perseu Comercio de Equipamento Para Informatic E 

Astronomica SA, which is based in Portugal. Each subsidiary has an accounting function which reports to the  
UK-based group finance team; and

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 process is centralised.

Identifying significant components

l  Significant components were identified through assessing their relative share of the key financial metrics including 
revenue and profit before tax. These metrics were used to identify components classified as ‘individually financially 
significant to the group’ and a full-scope audit was performed.

l  Other components were selected where we determined there to be a specific risk profile within those components 
and were included in the scope of our group audit procedures to provide sufficient coverage for the group’s results. 
For these components, specified audit procedures were performed.

l  All other components of the group were selected as ‘neither significant nor material’, and analytical procedures 

were performed.

Other Information

The other information comprises the information included in the financial statements, other than the financial statements 
and our auditor’s report thereon. The directors are responsible for the other information contained within the financial 
statements. Our opinion on the financial statements does not cover the other information and, except to the extent 
otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon. 

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

We have nothing to report in this regard.

Report of the Independent Auditor

Report of the Independent Auditor continued

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 their environment obtained in 
the course of the audit, we have not identified material misstatements in the strategic report or the directors’ report. 

Matters on which we are required to report by exception
We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to 
report to you if, in our opinion:

l  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
As explained more fully in the directors’ responsibilities statement set out on page 43, 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.

SDI Group plc 
Report of the Independent Auditor

Irregularities, including fraud, are instances of non-compliance with laws and regulations. The extent to which our 
procedures are capable of detecting irregularities, including fraud, is detailed below: 

l  We obtained an understanding of the legal and regulatory frameworks that are most applicable to the group and the 
parent company and the industry that they operate. We determined the most significant are those that relate to the 
financial reporting framework, being UK-adopted international accounting standards for the group, United Kingdom 
Generally Accepted Accounting Practice (for the parent company) and the Companies Act 2006, together with  
relevant tax compliance regulations, and other laws and regulations in areas where components operate. 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 practices. 

l  We inquired of management, the finance team, and the board of directors about the group’s and parent 

company’s policies and procedures relating to:

  l   The identification, evaluation, and compliance with laws and regulations;

  l   The detection and response of risks to fraud; and

  l   The establishment of internal controls to mitigate risks of fraud and non-compliance with laws and regulations.

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

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. Audit procedures performed by  
the engagement team to address these risks included: 

  l  Identifying and assessing the design and implementation of controls management has in place to prevent and 

   detect fraud;

  l  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; 

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

  l  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; 

l  The engagement partner’s assessment of the appropriateness of the collective competence and capabilities of the 

engagement team included consideration of the engagement team’s: 

  l  understanding of, and practical experience with, audit engagements of a similar nature and complexity, through  

   appropriate training and participation;

  l  knowledge of the industry in which the group and the parent company operate; and

  l  understanding of the legal and regulatory frameworks applicable to the group and the parent company. 

l  We communicated relevant laws and regulations and potential fraud risks to all engagement team members. We 
remained alert to any indications of fraud or non-compliance with laws and regulations throughout the audit.

l  We inquired of the component auditor to request details of any instances of non-compliance with laws and regulations 

that could give rise to a material misstatement of the group financial statements.

Notes to the Consolidated Financial Statements

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	2023	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	in	accordance	with	UK	adopted	
international	accounting	standards	and	with	those	parts	of	the	Companies	Act	2006	applicable		
to	companies	reporting	under	IFRS.	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	62-65.

The	Group	ended	FY23	with	net	debt	(excluding	lease	liabilities)	of	£13.3m	compared	to	a	net	cash	
position	of	£1.1m	as	at	30	April	2022	and	generated	free	cash	flow	(before	acquisition	consideration)	
of	£6.4m.	Free	cash	flow	was	lower	than	FY22	due	to	a	£3.5m	unwind	of	customer	advances	
received	in	previous	periods	and	a	£2.9m	increase	in	inventories	–	to	mitigate	against	component	
shortages	and	build	an	asset	for	shipping	to	a	customer	in	FY24.	This	was	offset	by	a	£2.7m	
reduction	in	debtors.	On	30	November	2022,	the	Group	reached	agreement	with	HSBC	to	exercise	
£5m	of	an	available	£10m	accordion	option,	which	increased	the	committed	loan	facility	from	£20m	
to	£25m.	£16m	was	drawn	down	under	this	facility	at	the	year-end	(see	note	22).	In	March	2023,	
HSBC	approved	an	extension	of	the	repayment	date	by	one	year	to	November	2025.	This	provides	
the	Group	with	greater	certainty	over	long-term	liquidity.	

The	Board	has	considered	the	potential	of	a	downturn	given	the	current	economic	environment.	
The	Group	is	in	a	strong	financial	position	with	available	facilities,	sufficient	headroom	on	all	
covenants	associated	with	the	revolving	credit	facility,	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,	
evaluated	a	severe	downside	scenario	and	performed	a	sensitivity	analysis,	all	of	which	the		
Board	considers	extremely	unlikely.	In	the	event	of	a	more	severe	scenario	(without	applying		
any	mitigations),	only	the	interest	cover	covenant	would	come	under	stress.	However,	mitigations	
would	be	obviously	applied	should	this	unlikely	scenario	present	itself,	such	as	(but	not	restricted	to)	
further	cost	cutting,	sale	and	leaseback	of	freehold	property	and	potential	disposal	of	assets.		
This	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.

The	company	has	changed	its	accounting	policy	regarding	the	accounting	for	deferred	and	
contingent	consideration	which	are	now	accounted	for	on	an	accruals	rather	than	cash	basis	as	
detailed	in	note	13	of	the	company	accounts.

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
Pension scheme
The	liabilities	in	respect	of	the	defined	benefit	pension	scheme	are	calculated	by	qualified	actuaries	
and	received	by	the	Group.	The	principal	uncertainty	lates	to	the	estimation	of	the	discount	rate,	life	
expectations	of	scheme	members,	future	investment	yields	and	general	market	conditions	for	factors	
such	as	inflation	and	interest	rates.	The	specific	assumptions	adopted	are	disclosed	in	detail	in	note	8.	

There	are	no	key	assumptions	concerning	future,	and	other	key	sources	of	estimation	uncertainty		
at	the	reporting	date	that	have	a	significant	risk	of	causing	a	material	misstatement	to	the	carrying	
amounts	of	assets	and	liabilities	within	the	financial	year.

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	31.

Carrying value of goodwill and other intangible assets
The	impairment	analysis	of	intangible	assets	is	based	upon	the	higher	of	fair	value	less	costs	to	sell	
(where	there	is	reliable	data)	and	future	discounted	cash	flows.	In	the	case	of	the	latter,	several	
assumptions	are	made	to	estimate	the	future	cash	flows	expected	to	arise	from	the	cash	generating	
unit	as	well	as	a	suitable	discount	rate	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	11.	

Assessment of the percentage of completion of long-term contract
The	Group’s	revenue	recognition	policy,	which	is	set	out	in	note	3,	requires	forecasts	to	be	made		
of	the	outcomes	of	long-term	contracts.	This	requires	estimates	of	labour	hours	and	rates,	and	
material	costs	to	determine	forecast	costs	to	completion	and	therefore	revenue	recognition	on	
each	long-term	contract.	Where	actual	costs	incurred	differ	to	forecast	costs,	or	where	forecast	
cost	estimates	change,	the	assessment	of	the	percentage	of	completion	of	long-term	contracts		
will	be	affected	and	therefore	revenue	and	profit	or	losses	recognised	impacted.

Principal Accounting Policies

The	principal	accounting	policies	adopted	are	consistent	with	those	of	the	annual	financial	
statements	for	the	year	ended	30	April	2022.	

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.	Freehold	property		
is	shown	at	historical	cost	less	accumulated	depreciation.	Depreciation	is	charged	to	the	income	
statement	on	a	straight-line	basis	over	the	estimated	useful	lives,	as	follows:

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

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

The	asset’s	residual	values	and	useful	lives	are	reviewed,	and	adjusted	is	appropriate,	at	each	balance	
sheet	date.	An	asset’s	carrying	amount	is	written	down	immediately	to	its	recoverable	amount	when	
an	indicator	of	impairment	is	identified.	Gains	and	losses	on	disposals	are	determined	by	comparing	
proceeds	with	carrying	amount.	These	are	included	in	the	income	statement.

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.

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	 “Merger	relief	reserve”	represents	the	premium	on	shares	issued	for	an	investment	in	a	subsidiary	

which	has	been	classified	as	a	merger	relief	reserve	instead	of	share	premium.

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

in	overseas	subsidiaries.

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	 “Non-controlling	interest”	represents	the	proportionate	share	of	the	identifiable	net	assets	
on	acquisition	and	subsequent	share	of	result	following	this	of	any	subsidiary	where	the	
shareholdings	held	by	the	Parent	Company	is	less	than	100%.

l	 “Retained	earnings”	represents	retained	profits.	Under	Portuguese	law,	a	portion	of	their	retained	
earnings	must	be	transferred	to	a	legal	reserve	each	year,	and	as	such	this	is	not	distributable.

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.

Defined benefit plans
Under	the	Group’s	defined	benefit	plans,	the	amount	of	pension	benefit	that	an	employee	will	
receive	on	retirement	is	defined	by	reference	to	the	employee’s	length	of	service	and	final	salary.	
The	legal	obligation	for	any	benefits	remains	with	the	Group,	even	if	plan	assets	for	funding	the	
defined	benefit	plan	have	been	set	aside.	Plan	assets	may	include	assets	specifically	designated		
to	a	long-term	benefit	fund	as	well	as	qualifying	insurance	policies.

The	liability	recognised	in	the	consolidated	statement	of	financial	position	for	defined	benefit		
plans	is	the	present	value	of	the	defined	benefit	obligation	(DBO)	at	the	reporting	date	less	the		
fair	value	of	plan	assets.

Management	estimates	the	DBO	annually	with	the	assistance	of	independent	actuaries.		
This	is	based	on	standard	rates	of	inflation,	salary	growth	rate	and	mortality.	Discount	factors		
are	determined	close	to	the	end	of	each	annual	reporting	period	by	reference	to	high	quality	
corporate	bonds	that	are	denominated	in	the	currency	in	which	the	benefits	will	be	paid	and		
have	terms	to	maturity	approximating	the	terms	of	the	related	pension	liability.

Service	cost	on	the	Group’s	defined	benefit	plan	is	included	in	employee	benefits	expense.	
Employee	contributions,	all	of	which	are	independent	of	the	number	of	years	of	service,	are	treated	
as	a	reduction	of	service	cost.	Net	interest	expense	on	the	net	defined	benefit	liability	is	included		
in	finance	costs.	Gains	and	losses	resulting	from	remeasurements	of	the	net	defined	benefit		
liability	are	included	in	other	comprehensive	income	and	are	not	reclassified	to	profit	or	loss	in	
subsequent	periods.

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.

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	goods,	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	goods	is	recognised	mainly	at	a	point	in	time,	at	which	the	customer	obtains	
control	of	the	asset,	however	there	are	some	instances	across	the	Group	where	revenue	is	
recognised	over	time.	Such	products	have	been	determined	to	be	bespoke	in	nature,	with	no	
alternative	use.	Where	there	is	also	an	enforceable	right	to	payment	for	work	completed,	the	criteria	
for	recognising	revenue	over	time	have	been	deemed	to	have	been	met.	Revenue	is	recognised		
on	an	input	basis	as	work	progresses	and	progress	is	measured	with	reference	to	the	actual	costs	
incurred	as	a	proportion	of	the	total	costs	expected	to	be	incurred	under	the	contract.	

This	is	not	a	significant	part	of	the	Group’s	business	as	for	the	most	part,	where	goods	are	bespoke	
in	nature,	it	is	the	Group’s	judgement	that	the	products	can	be	broken	down	to	standard	component	
parts	with	little	additional	cost	and	therefore	has	an	alternative	use,	or	there	is	no	enforceable	right	
to	payment	for	work	performed.	In	these	cases,	the	judgement	is	made	that	the	requirements	for	
recognising	revenue	over	time	are	not	met	and	revenue	is	recognised	when	control	of	the	finished	
product	passes	to	the	customer.

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	the	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	currently	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.

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.

Investments
An	associate	is	an	entity	over	which	the	Group	is	in	a	position	to	exercise	significant	influence,	but	
not	control	or	joint	control,	through	participation	in	the	financial	and	operating	policy	decisions	of	
the	investee.	Significant	influence	is	the	power	to	participate	in	the	financial	and	operating	policy	
decisions	of	the	investee	but	without	control	or	joint	control	over	these	policies.	The	results	and	
assets	and	liabilities	of	associates	are	incorporated	in	these	financial	statements	using	the	equity	
method	of	accounting.	Investments	in	associates	are	carried	in	the	Consolidated	Balance	Sheet	at	
cost	as	adjusted	by	post-acquisition	changes	in	the	Group	share	of	the	net	assets	of	the	associate.	
Losses	of	an	associate	in	the	excess	of	the	Group’s	interest	in	that	associate	(which	includes	any	
long-term	interests	that,	in	substance,	form	part	of	the	Group’s	net	investments	in	the	associate)	are	
recognised	only	to	the	extent	that	the	Group	has	incurred	legal	or	constructive	obligations	or	made	
payments	on	behalf	of	the	associate.

Any	excess	of	the	cost	of	acquisition	over	the	Group’s	share	of	the	fair	value	of	the	identifiable	net	
assets	of	the	associate	at	the	date	of	acquisition	is	recognised	in	goodwill.	The	goodwill	is	included	
within	the	carrying	value	of	the	investment	and	is	assessed	for	impairment	as	part	of	that	investment.	
Any	deficiency	of	the	cost	of	the	acquisition	below	the	Group’s	share	of	the	fair	values	of	the	
identifiable	net	assets	of	the	associate	at	the	date	of	acquisition	(i.e.,	discount	on	acquisition)	is	
credited	in	profit	and	loss	in	the	year	of	acquisition.	Where	a	Group	company	transacts	with	an	
associate	of	the	Group,	profits	and	losses	are	eliminated	to	the	extent	of	the	Group’s	interest	in	the	
relevant	associate.	Losses	may	provide	evidence	of	an	impairment	of	the	asset	transferred	in	which	
case	appropriate	provisioning	is	made	for	impairment.

Where	the	Group	disposes	of	its	entire	interest	in	an	associate,	a	gain	or	loss	is	recognised	in	the	
income	statement	on	the	difference	between	the	amount	received	on	the	sale	of	the	associate	less	
the	carrying	value	and	costs	of	disposal.

Alternative Performance Measures

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).	Some	items,	e.g.,	impairment	of	intangibles	are	both	non-cash	and	exceptional.

Health	and	Fistreem,	the	Atik	brands	Atik	Cameras,	Opus	and	Quantum	Scientific	Imaging,	and	
Graticules	Optics.	These	businesses	share	significant	characteristics	including	customer	application,	
technology,	and	production	location.	Revenues	derive	from	the	sale	of	instruments,	components	for	
OEM	customers’	instruments,	from	accessories	and	service	and	from	licence	income.

The	Sensors	&	Control	segment	combines	our	Sentek,	Astles	Control	Systems,	Applied	Thermal	
Control,	Thermal	Exchange,	MPB	Industries,	Chell	Instruments,	Monmouth	Scientific,	Uniform	
Engineering,	Scientific	Vacuum	Systems,	Safelab	Systems,	LTE	Scientific	and	Fraser	Anti-Static	
Techniques	businesses.	All	of	these	businesses	provide	products	that	enable	accurate	control	of	
scientific	and	industrial	equipment.	Their	revenues	also	derive	from	the	sale	of	instruments,	major	
components	for	OEM	customers’	instruments,	and	from	accessories	and	service.

The	Board	of	Directors	reviews	operational	results	of	these	segments	on	a	monthly	basis	and	
decides	on	resource	allocations	to	the	segments	and	is	considered	the	Group’s	chief	operational	
decision	maker.

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,	609,200	of	such	options	were	granted	under	these	schemes,		
at	exercise	prices	ranging	from	£1.565	to	£1.630.	The	weighted	average	remaining	contractual	life		
of	all	outstanding	options	under	these	schemes	is	5.47	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	 0%

l	 volatility	 47%-50%

l	 expected	life	of	option	 3	years.

The	charge	for	the	year	ended	30	April	2023	was	£351k	(2022:	£313k).	

During	the	year,	the	Group	acquired	LTE	Scientific	Limited	which	already	operated	a	defined	benefit	
pension	scheme	at	the	point	of	acquisition.	The	pension	surplus	has	not	been	recognised	as	the	
Group	does	not	have	an	unconditional	right	to	benefit	therefrom.

Defined benefit plan
The	Group	operates	a	funded	pension	plan	in	the	UK.	The	plan	operates	on	a	defined	benefit	basis	
and	benefits	ceased	to	accrue	with	effect	from	30	June	1997.

The	plan	exposes	the	Group	to	actuarial	risks	such	as	investment	risk,	longevity	risk	and	inflation	risk:

l	 Investment	risk	–	Investment	risk	–	The	plan	assets	at	30	April	2023	are	heavily	equity	related.

l	 Longevity	risk	–	The	Group	is	required	to	provide	benefits	for	life	for	the	members	of	the	

defined	benefit	liability.	Increase	in	the	life	expectancy	of	the	member	will	increase	the	defined	
benefit	liability.

l	 Inflation	risk	–	A	significant	proportion	of	the	defined	benefit	asset	is	linked	to	inflation.	An	increase	

in	the	inflation	rate	will	increase	the	Group’s	liability.	A	portion	of	the	plan	assets	are	inflation-
linked	debt	securities	which	will	mitigate	some	of	the	effects	of	inflation.

Based	on	historical	data,	the	Group	expects	contributions	of	£nil	to	be	paid	for	2024.

The	asset	not	recognised	for	the	Group’s	defined	benefit	obligation	(‘DBO’)	is	represented	net	of	
plan	assets	in	accordance	with	IAS	19.131(a)	and	(b).	It	consists	of	the	following	amounts:

These	assumptions	were	developed	by	management	with	the	assistance	of	independent	actuaries.	
Discount	factors	are	determined	close	to	each	period-end	by	reference	to	market	yields	of	high-
quality	corporate	bonds	that	are	denominated	in	the	currency	in	which	the	benefits	will	be	paid	and	
that	have	terms	to	maturity	approximating	to	the	terms	of	the	related	pension	obligation.	Other	
assumptions	are	based	on	current	actuarial	benchmarks	and	management’s	historical	experience.

The	present	value	of	the	DBO	was	measured	using	the	defined	accrued	benefit	method.

The	weighted	average	duration	of	the	defined	benefit	obligation	at	30	April	2023	is	13	years.

Plan assets
Plan	assets	do	not	comprise	any	of	the	Group’s	own	financial	instruments	or	any	assets	used	by	Group	
companies.	All	equity	and	debt	instruments	have	quoted	prices	in	active	markets	(Level	1).	Fair	values	
of	real	estate	investments	do	not	have	quoted	prices	and	have	been	determined	based	on	professional	
appraisals	that	would	be	classified	as	Level	3	of	the	fair	value	hierarchy	as	defined	in	IFRS	13.

Defined benefit plan expenses
Amounts	not	recognised	in	profit	or	loss	related	to	the	Group’s	defined	benefit	plans	are	as	follows:

Amounts	not	recognised	in	other	comprehensive	income	related	to	the	Group’s	defined	benefit

The	income	of	£219k	resulting	from	the	remeasurement	of	the	defined	benefit	liability/asset	is	
included	in	the	consolidated	statement	of	other	comprehensive	income	within	items	that	will	not	be	
reclassified	subsequently	to	profit	or	loss.

Changes in the significant actuarial assumptions
The	calculation	of	the	net	defined	benefit	asset	is	sensitive	to	the	significant	actuarial	assumptions	
mentioned	above.	The	following	table	summarises	the	effects	of	changes	in	these	actuarial	
assumptions	on	the	defined	benefit	liability	at	30	April	2023:

Discount	rate	0.5%	pa	lower
Inflation	rate	0.5%	pa	higher

The	present	value	of	the	defined	benefit	obligation	has	been	calculated	with	the	same	method	
(defined	accrued	benefit)	as	the	defined	benefit	obligation	recognised	in	the	consolidated	statement	
of	financial	position.	The	sensitivity	analyses	are	based	on	a	change	in	one	assumption	while	not	
changing	all	other	assumptions.	This	analysis	may	not	be	representative	of	the	actual	change	in	the	
defined	benefit	obligation	as	it	is	unlikely	the	change	in	any	of	the	assumptions	would	occur	in	
isolation	of	one	another	as	some	of	the	assumptions	are	correlated.

Capitalised	development	costs	include	amounts	totalling	£243k	(2022:	£31k)	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:

During	the	year,	Goodwill	was	tested	for	impairment	in	accordance	with	IAS	36.	The	recoverable	
amount	of	the	Group’s	Goodwill	was	assessed	by	reference	to	the	Value-In-Use	(“VIU”)	calculations	
derived	from	3-year	budgeted	cash	flows	and	2	years	of	extrapolated	cash	flows	using	inflationary	
growth	rates	(2%	to	10%	p.a.).	This	is	equivalent	to	a	5-year	forecast	period,	which	is	the	maximum	
period	expected	unless	a	longer	period	is	justifiable.	Management’s	key	assumption	for	all	cash	
generating	units	and	resulting	cash	flows	is	to	maintain	market	share	in	their	markets.	Thereafter,		
the	VIU	is	based	on	estimated	long-term	growth	(“LTG”)	rates	of	2%	(2022:	2%).

A	risk-adjusted,	pre-tax	discount	rate	of	17.0%	(2022:	13.6%)	was	used	for	all	companies	except		
for	the	Monmouth	Scientific	incorporating	Uniform	Engineering	and	Moorfield	Technology	
(‘Monmouth	Scientific’),	Synoptics	and	LTE	Scientific	CGUs,	where	a	risk-adjusted,	pre-tax	discount	
rate	of	15.33%	was	adopted.	This	latter	rate	was	judged	to	be	appropriate	for	the	Monmouth	
Scientific,	Synoptics	and	LTE	Scientific	CGUs	as	their	asset	structures	(i.e.,	weight	of	the	fixed	assets	
vs	the	VIU/carrying	value)	differ	from	those	observed	for	the	Group	and	other	CGUs.	As	a	significant	
part	of	the	CGU	value	could	be	securitised	and	financed	by	debt	(building,	plant	and	equipment),	
these	particular	CGUs	are	deemed	to	have	a	lower	weighted	average	cost	of	capital	(WACC).

The	Directors	have	concluded	that	an	impairment	totalling	£3.5m	has	arisen	in	relation	to	
Monmouth	Scientific’s	goodwill	and	intangible	assets,	which	has	been	subsequently	recognised		
in	the	Consolidated	income	statement	and	statement	of	comprehensive	income	as	an	exceptional	
item.	Approximately	£1m	of	the	impairment	is	caused	by	IFRS	16	not	permitting	leased	buildings		
to	be	revalued	during	the	lease	in	the	absence	of	a	rent	renegotiation.

The	£3.5m	impairment	includes	the	entire	goodwill	balance	of	£3.2m	and	£0.3m	of	customer	
relationships.	At	the	year	end,	£1.6m	of	customer	relationships/trade	names	remains	as		
intangible	assets.	

No	other	impairments	have	been	recognised	across	any	other	CGUs.

The	Directors	have	further	considered	the	sensitivity	of	the	key	assumptions	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	Fraser	Anti-Static	Techniques	CGU,	for	
which	a)	there	is	a	1%	headroom	above	carrying	cost	of	the	CGU,	based	on	the	VIU	applying	the	
base	assumptions	and	b)	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	
become	de	minimis:

l	 discount	rate	increased	to	from	17%	to	17.2%

l	 sales	volume	reduced	by	0.5%,	with	no	action	on	costs

l	 operating	margins	reduced	by	0.5%

The	average	remaining	amortisation	period	of	intangible	assets	excluding	Goodwill	is	8.1	years	
(2022:	10.1	years).

On	21	October	2022,	the	Company	acquired	100%	of	the	share	capital	of	Fraser	Anti-Static	
Techniques	Limited,	a	company	incorporated	in	England	and	Wales.	Fraser	Anti-Static	Techniques		
in	turn	owned	100%	of	the	share	capital	of	Fraser	Elektrostatik	GmbH,	a	company	incorporated	in	
Germany,	and	70%	of	the	share	capital	of	Shanghai	Fraser	Static	Technology	Co.,	Ltd,	a	company	
incorporated	in	China.	The	other	30%	of	Shanghai	Fraser	Static	Technology	Co.,	Ltd	is	owned	by	
management,	based	in	China,	which	has	been	accounted	for	as	an	associated	undertaking	in	the	
year.	The	results	and	assets	and	liabilities	of	this	associate	are	incorporated	in	these	financial	
statements	using	the	equity	method	of	accounting.

The	Group	has	leases	for	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	13).

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	2023	were	as	follows:

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	(2022:	£260k)	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	£1.0m	(2022:	£1.3m).	

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.	Deferred	tax	deductions	totalling	£117k	(2022:	£357k)	have	been	recognised	directly	in	equity.

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.

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	£5,533k	were	recognised	as	
revenue	during	the	current	year.

At	the	end	of	the	year,	contingent	consideration	of	£961k	remains	outstanding	in	relation	to	the	
acquisition	of	Scientific	Vacuum	Systems	Limited.	

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

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

expenditure	will	be	incurred	in	the	next	financial	year.

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.	On	1	November	2021	the	Group	renewed	and	
expanded	its	committed	loan	facility	with	HSBC	to	£20m,	with	an	accordion	option	of	an	additional	
£10m	and	with	a	termination	date	of	1	November	2024	extendable	for	two	further	years.	On	30	
November	2022,	the	Group	reached	agreement	with	HSBC	to	exercise	£5m	of	an	available	£10m	
accordion	option,	which	increased	the	committed	loan	facility	from	£20m	to	£25m.	The	balance	of	
the	accordion	option	(£5m)	remains	available	to	the	Group	(at	the	discretion	of	HSBC)	for	future	
exercise.	On	29	March	2023	the	termination	date	was	extended	by	a	further	year	to	1	November	
2025.	This	is	extendable	by	another	year	at	HSBC’s	discretion.	The	revolving	facility	is	available	for	
general	use.	The	facility	has	covenants	relating	to	leverage	(net	debt	to	EBITDA)	and	interest	cover.

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	£160k	(2022:	£40k)	annually,	based	on	the	loan	
outstanding	at	30	April	2023.	

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	2023	an	adverse	movement	in	the	dollar	of	5%		
would	result	in	a	reduction	in	the	Group’s	equity	and	profit	or	loss	of	£51k	(2022:	£49k).	An	adverse	
movement	in	the	Euro	of	5%	would	result	in	a	reduction	in	the	Group’s	equity	and	profit	or	loss	of	
£94k	(2022:	£115k).	An	adverse	movement	in	Chinese	Yuan	of	5%	would	result	in	a	reduction	in		
the	Group’s	equity	and	profit	or	loss	of	£24k	(2022:	£nil).

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

US	Dollars

2022

2,416
–

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	currently	
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	£16,711k	(2022:	£12,650k).		
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	18.		
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.

The	assets	and	liabilities	acquired	were	as	follows:

LTE	Scientific	Limited	contributed	£6,193k	revenue	and	approximately	£525k	to	the	Group’s	profit	
before	tax	for	the	period	between	the	date	of	acquisition	and	the	balance	sheet	date,	not	including	
£95k	of	acquired	intangible	asset	amortisation.

If	the	acquisition	of	LTE	Scientific	Limited	had	been	completed	on	the	first	day	of	the	financial		
year,	the	additional	impact	on	group	revenues	for	the	period	would	have	been	£1,636k	and	the	
additional	impact	on	group	profit	would	have	been	approximately	£93k,	before	additional	£32k		
of	amortisation	expense.

The	goodwill	of	£676k	arising	from	the	acquisition	relates	to	the	assembled	workforce	and	to	
expected	future	profitability,	synergy	and	growth	expectations.

A	third-party	expert	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	14.7%	and	15%		
were	selected.

The	last	financial	year	for	LTE	Scientific	Limited	before	the	acquisition	completed	was	to		
31	December	2021.	LTE	Scientific’s	current	financial	year	has	been	extended	by	four	months		
to	April	2023	to	align	with	that	of	SDI	Group	plc.

On	21	October	2022,	the	Company	acquired	100%	of	the	share	capital	of	Fraser	Anti-Static	
Techniques	Limited,	a	company	incorporated	in	England	and	Wales,	for	a	consideration	payable		
in	cash.

Fraser	Anti-Static	Techniques	Limited	contributed	£4,966k	revenue	and	approximately	£930k	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	Fraser	Anti-Static	Techniques	Limited	had	been	completed	on	the	first	day	of		
the	financial	year,	the	additional	impact	on	group	revenues	for	the	period	would	have	been	£4,695k	
and	the	additional	impact	on	group	profit	would	have	been	approximately	£671k,	before	additional	
£152k	of	amortisation	expense.

The	goodwill	of	£4,824k	arising	from	the	acquisition	relates	to	the	assembled	workforce	and	to	
expected	future	profitability,	synergy	and	growth	expectations.

A	third-party	expert	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	8.5%		
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	Fraser	Anti-Static	Techniques	Limited	before	the	acquisition	closed	was	to	
30	November	2021.	Its	current	financial	year	has	been	extended	by	five	months	to	April	2023	to	
align	with	that	of	SDI	Group	plc.

Notes to the Company Financial Statements  

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.	

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	reserve	relief”	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	Company	
did	not	recognise	deferred	tax	assets	of	£260k	(2022:	£260k)	in	respect	of	losses.	Total	losses		
(provided	and	unprovided)	totalled	£1.0m	(2022:	£1.3m).	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.

All	debtors	fall	due	within	one	year	of	the	balance	sheet	date.	No	provisions	are	made	for		
inter-group	debtors	as	the	credit	risk	is	not	thought	to	be	significant.

Related Party Transactions 

Transactions	with	directors	are	disclosed	within	the	Directors’	Remuneration	Report	and	note	7		
to	the	consolidated	financial	statements.	The	Company	is	not	required	to	disclose	transactions	with	
its	wholly	owned	subsidiaries.

Prior Year Restatement 

As	a	result	of	a	change	in	accounting	policy,	a	prior	year	restatement	has	been	made	to	account		
for	deferred	consideration	on	an	accruals	basis.	As	a	result	of	this	restatement,	the	investments	and	
other	creditors	balances	in	the	year	ended	30	April	2022	have	increased	by	£3,348k,	from	£36,651k	
to	£39,999k.	The	previously	reported	profits	of	£7,443k	and	net	assets	of	£30,869k	are	unchanged.

Ultimate Controlling Party 

The	Directors	believe	that	there	is	no	overall	controlling	party.

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.	On	1	November	2021	the	Group	renewed	and	
expanded	its	committed	loan	facility	with	HSBC	to	£20m,	with	an	accordion	option	of	an		
additional	£10m	and	with	a	termination	date	of	1	November	2024	extendable	for	two	further	years.	
On	30	November	2022,	the	Group	reached	agreement	with	HSBC	to	exercise	£5m	of	an	available	
£10m	accordion	option,	which	increased	the	committed	loan	facility	from	£20m	to	£25m.	The	
balance	of	the	accordion	option	(£5m)	remains	available	to	the	Group	(at	the	discretion	of	HSBC)		
for	future	exercise.	On	29	March	2023	the	termination	date	was	extended	by	a	further	year	to		
1	November	2025.	This	is	extendable	by	another	year	at	HSBC’s	discretion.	The	revolving	facility		
is	available	for	general	use.	The	facility	has	covenants	relating	to	leverage	(net	debt	to	EBITDA)		
and	interest	cover.
