P ROPRIETARY M ETHO D OF 
F RICTION GRIP ENGINEERING

Plexus HG® technology, is a simple scientific 
method of design for metal interface seals, used to 
permanently contain METHANE GAS in wellheads, 
throughout the life of a producing well.

The seal system comprises of multiple integral 
radiused bump rings, which interact directly with 
the wellhead bore, to halve the number of leak paths 
past the annulus, using a series of redundant gallery 
seals. A preload above yield is carefully delivered 
and recorded by the externally controlled horizontal 
deflection of the housing wall against solid hanger 
bodies, thereby equally distributing perimeter 
stress, in compliance with the principles of Hertzian 
Stress Theory (HST).

The system stays permanently rigid, guarantees 
life-cycle integrity and is maintenance-free, using 
re-usable components. By matching materials at the 
seal interface, bi-metallic corrosion is prevented and 
multiple metal seals are used to anticipate the pace 
of chemical degradation, throughout field-life.

Wellheads

Production wellheads, both surface and subsea 
have all benefitted from POS-GRIP. Casing 
and tubing hangers can be gripped, but 
POS-GRIP can also be used to support 
wearbushings, BOP test tools and seal 
sleeves.

Connectors

POS-GRIP is ideal for high integrity, low 
fatigue connector applications. Wellhead 
connectors, riser connectors, subsea jumper 
connectors, pipeline connectors, and even 
vessel mooring connectors can benefit from 
the simplicity of POS-GRIP.

Metal-to-metal sealing

Wellheads and connectors can both benefit 
from the direct contact created when the 
POS-GRIP metal to metal HG® seal is 
activated.

Operational Overview 

Revenue streams are derived from the direct rental and sale of Plexus products together with the licencing of the 
Plexus’ POS-GRIP® method of friction-grip engineering technology to third parties, including SLB (previously 
Schlumberger). The strategy is to establish the Company’s proprietary and patented leak-proof wellhead systems, 
applications and specialist engineering solutions across the oil and gas industry, whilst helping to meet ESG and 
net zero goals by offering ‘through the BOP’ (Blow out Preventer) wellhead designs, and leak-proof seals capable 
of maintaining their integrity for the life of the well thereby avoiding costs associated with maintenance and well 
shut ins.

Chief Executive Ben Van Bilderbeek said: 

“During the year to 30th June 2023, the Group made a loss before tax of £4.23m compared to a loss in the prior 
year of £5.56m. Although revenues were lower than the prior year, the board’s focus on reversing these losses and 
the decisions taken as part of the revised strategy has begun to have a positive impact with significantly increased 
revenues and a return to profitability anticipated for the 2023/24 financial year. Current activities are centred around 
our re-entry into the drilling from Jack-up rigs exploration rental wellhead business, sale of surface production 
wellheads  and  the  provision  of  special  solutions  and  applications  to  operators,  for  example  in  the  Plug  and 
Abandonment (‘P&A’) market sector. At the same time, we are developing our licensee relationship with SLB 
where we have licenced certain surface production wellhead IP and technology. 

Looking at the macroeconomic and oil and gas (‘O&G’) sector backdrop, the clock is ticking as the world looks to 
achieve its 2030-2050 net zero goals. While the shift from an established fossil-fuel intensive hydrocarbon-based 
energy system to one that will focus on renewables and nuclear is irrefutably the right path forward, at the same 
time reality must prevail as it is becoming increasingly clear that O&G will for decades continue to play a key role 
in the energy mix until various complex cost and infrastructure challenges are overcome, including the establishment 
of robust and reliable critical supply chains. Importantly, natural gas is recognised as the key transition hydrocarbon, 
and Plexus’ proprietary wellhead and HG® seal designs have a unique role to play in terms of their capability of 
delivering leak-proof performance and solutions for the smaller molecules and higher pressure and temperatures 
associated with gas exploration and production drilling. Emphasising the gas opportunity, the CEO of Baker Hughes 
in an interview with the Financial Times earlier this month declared that there is a long lifeline for natural gas and 
LNG and went one step further when he said that: “If you look at affordability, security and sustainability, natural 
gas and LNG is not just a transition fuel but a destination fuel”. 

BP believes that investment in O&G production will be needed for the next 30 years to avoid energy shortages and 
fluctuating prices, while the International Energy Agency (‘IEA’) suggests that although oil, gas and coal are on 
course to hit a peak in the next few years, having held a circa 80% share of the global energy mix for decades, they 
will continue to be just above 60% of the mix by 2050. The IEA’s Oil 2023 report forecasts demand to grow to 
105.7mn barrels per day in 2028 – a new global high, and 6% more than 2022 levels. Sentiment in the sector is 
therefore becoming more positive with Wood Mackenzie predicting that offshore exploration and drilling activity 
will grow 20% by 2025. 

At the same time as O&G demand remains strong, there are clear signs of intensifying pressure to decarbonise, 
and  the  O&G  industry  is  inevitably  coming  under  increased  scrutiny  to  drastically  reduce  its  future  carbon 
emissions. Consequently, it is now readily understood that whilst O&G production and consumption continues, it 
needs to be as green as possible in terms of reduced emissions (which are often unintentional leaks), especially 
regarding methane which is so much more harmful to the environment than CO2. 

The US is leading this charge: Administrator Michael Regan at the Environmental Protection Agency (‘EPA’) 
recently said that no O&G infrastructure was “getting out of jail free” under pending methane rules. Meanwhile, 
California is looking to pass legislation that will require companies to report carbon emissions from supply chains 
or risk being excluded from the market; this mandate is the first of its kind in the US, but other states and countries 
are likely to follow suit. Such legislation according to reports seek to use consumer protection, racketeering, product 
liability and other laws to seek damages to pay for climate related costs. The product liability category is particularly 
relevant  for  Plexus  as  we  believe  that  our  leak-proof  wellhead  equipment  seals  can  perform  in  a  way  that 
conventional  equipment  and  seals  cannot  for  scientifically  verifiable  reasons,  thereby  protecting  both  the 
environment and the operator. 

Plexus has always argued and continues to argue that leak prevention is so much more effective than after the event 
questionable leak ‘cures’, and I must believe that at some stage where an E&P company is faced with the choice 
between specifying a conventional wellhead design with leak history, versus a proven design with no leak history 
that our time will come. A further incentive for such developments apart from O&G companies simply being 
motivated to do the ‘right thing’ by selecting equipment that can help deliver emission reduction, are powerful 
pending financial incentives such as President Joe Biden’s Inflation Reduction Act which will introduce a charge 
of $900 USD per tonne of methane emitted in 2024, rising to $1,500 USD per tonne in 2026. 

Bearing in mind that our proven long term leak-proof metal sealing technology for gas service wellheads has been 
around for many years, it begs the question as to why preventing leaks from wellhead annular seals has not been 
made a priority, and why the focus continues to be on monitoring and cure rather than prevention?

Our explanation is simple, and twofold: 

1.

2.

Historically, I believe that the O&G industry has been conditioned to ‘accept’ that all wellhead systems have 
a point at which internal annular seals fail and that the need to re-energise seals is considered an unavoidable 
aspect of regular field maintenance requirements rather than being seen as a design flaw. 

In the early days, the focus on hydrocarbon exploration and production was on oil and as such, the equipment 
was  designed  for  oil,  which  has  larger  molecules  and  is  easier  to  contain  than  gas. Therefore,  because 
conventional gas wellhead equipment evolved rather than was designed with a leak- proof purpose in mind, 
the compromises that have always existed I believe have now become maintenance items, and therefore 
continue today. 

Consequently, although over the years we have worked on some very exciting, extreme wellhead pressure and 
temperature contracts and specialised projects, our technology has not yet broken into the volume mainstream. 

However, with the support of various forward-thinking international conglomerates, which recognise the value and 
unique capabilities of our technology, including SLB (previously Schlumberger), and with market sentiment moving 
in our favour as companies look for new ideas and opportunities to cut carbon emissions, I believe that Plexus will 
benefit accordingly. 

Positively, Plexus’ traditional home market, the North Sea, is beginning to see a revival after a severe downturn 
around 2015 which massively impacted the wider industry and Plexus, as we had been dependant on exploration 
drilling activity. While the UK Continental Shelf (‘UKCS’) is perhaps inevitably facing a “natural long-term 
decline”  as  suggested  by  Offshore  Energies  UK  director  Mike  Tholen,  awareness  is  growing  that  if  it  isn’t 
replenished with exploration activity, the UK will have no choice but to increase its reliance on imports, which in 
turn is a threat to the UK’s energy security. This will further exacerbate the emissions issue given O&G production 
closer to home is a far greener option than shipping products such as liquified natural gas (‘LNG’) from across 
the Atlantic. 

Accordingly, in July 2023, the UK Government committed to granting 100 plus new licences to extract O&G from 
the North Sea and bolster its energy security. In September 2023, Britain’s largest undeveloped oil field, Rosebank, 
was approved for drilling by the government regulator with production scheduled to begin by 2027, which is a 
strong indication of the change in sentiment. Furthermore, in October 2023 it was announced that a further twenty-
seven licences for O&G production have been granted, and Energy Secretary Claire Coutinho could not have put 
it better when she said, “As recognised by the independent Climate Change Committee, we’ll continue to need 
O&G over the coming decades as we deliver net zero. It’s therefore common sense to reduce our reliance on foreign 
imports and use our own supply – it’s better for our economy, the environment and our energy security”. Having 
re-entered the Jack-up exploration rental wellhead market with SLB equipment and sales support, we are well 
positioned to support such opportunities, in addition to the sale of production wellheads, P&A and special projects 
where unique POS-GRIP solutions can be developed. 

We  have  also  been  looking  at  options  to  apply  our  patented  method  of  friction-grip  engineering  to  other 
decarbonising emerging industries such as carbon capture and storage (‘CCS’), hydrogen, geothermal and offshore 
wind engineering challenges. In line with this, our R&D team based in Aberdeen continue to design and develop 
new products that support the needs of existing and potential customers. 

Another key target market is global offshore decommissioning. Valued at US$5.25 billion in 2021, this sector is 
forecast to grow at a CAGR of 7.6% to $10.07 billion in 2030 (source: Polaris Market Research). With around 
2,100 North Sea wells expected to be decommissioned over the next decade – around 200 per year – at an average 
cost of £7.8m per well, it is hardly surprising that a third of the spend is in Europe. Once again, the market is being 
driven by the rising focus on initiatives to lower climate-warming emissions. 

With this background, we were delighted to have won a purchase order for P&A equipment and services from 
Oceaneering International Services Limited at the end of the last financial year (June 2022). This successful project, 
which generated revenue of circa £850,000 for Plexus during the 2023 calendar year, was approximately 70% 
higher than original estimates. We envisage that this successful project will lead to other similar work in the North 
Sea and internationally both with Oceaneering and other customers Indeed post period end we announced two P&A 
related projects in the North Sea involving the rental of our Exact adjustable wellhead system, the most recent 
being for Neptune Energy UK announced in November 2023. 

In summary, our Company’s future success remains our key focus. At the same time we can help to address society’s 
demands for O&G operators to be responsible players through the supply of our unique technology which can 
contribute to achieving emission reduction targets, As a major shareholder in Plexus my interests are clearly aligned

with all our shareholders, and my confidence in the future was evidenced during the year by my provision of a 
£1.5m convertible loan, and a £700,000 loan. Although there is still some debate about the extent of the impact 
humanity has on global warming, the current 1.5-degree centigrade cap will be bolstered by better technology, and 
in this respect I have no doubt that Plexus’ proprietary POS-GRIP IP and its wellhead equipment designs will 
achieve the recognition they deserve, and I look forward to reporting further progress over the coming months.

Plexus Holdings plc Annual Report 2023

Chairman’s Statement 

Overview 

Plexus is a technology and engineering driven business centred on the rental and sale of wellhead equipment for 
exploration and production O&G drilling and P&A markets. Historically, the industry has developed over many 
decades what Plexus terms conventional wellhead design and sealing solutions, and in many parts of the world the 
lowest technical requirement available at the cheapest price prevails when it comes to equipment selection and 
tender  outcomes.  Conversely,  Plexus  has  always  pushed  for  ways  to  significantly  enhance  the  safety  and 
performance of products offered and which we maintain result in a significantly improved value proposition for 
the end user, especially when considered over the life of a well where expensive remedial work and shut ins leading 
to lost production are concerned. 

With strong and in many cases regulatory demands being made on the industry to reduce or avoid completely 
methane emissions, the main component of natural gas, leak-proof wellhead performance should be increasingly 
demanded, and we believe that this lies behind the recognition we have received from licensees for our technology. 
Plexus’ proprietary products are invariably protected by patented IP, such as POS-GRIP technology applications 
and “HG” metal-to-metal seals. The Company has demonstrated over many years that its products and technology 
perform over a wide range of products and applications whilst at the same time delivering green ESG and net zero 
compliant  features  in  relation  to  being  “through  the  BOP”  and  most  importantly  offering  leak-proof  sealing 
throughout the life of a well. 

As well as supporting licensees where the goal is to deploy the Plexus technology on a worldwide basis in markets 
that Plexus is best placed to reach through its licencee partners, the Company continues to pursue surface and 
subsea wellhead opportunities organically. In addition to this, Plexus is now gaining traction in the pursuit of rental 
opportunities in the Jack-up exploration wellhead business following a licensing deal with SLB, which enables 
Plexus to offer both Exact exploration wellhead and Centric mudline suspension systems. 

Business progress 

The Group’s revenues decreased in the 12 months to 30 June 2023 to £1.49m (2022: £2.31m), with a reduced loss 
before tax of £4.23m compared to loss of £5.56m in the prior year. Importantly, £3.64m of revenues are included 
in deferred income and will be recognised in the 2023/24 financial year. 

The global outlook for growth in O&G activities is now stronger than it has been for many years resulting in a 
pickup in activity across our core markets – exploration drilling, development wells and the P&A market. In the 
North Sea, where the reduction in activity was particularly pronounced over the past few years, the higher O&G 
prices, and the growing support for O&G development over the longer term as part of a more realistic net zero 
transition timetable, have resulted in a number of orders and increased tender opportunities. 

The most significant contract win was the special project announced in March 2023 to supply POS-GRIP “HG” 
wellhead system and sealing technology for a specialised subsea application. The value of this contract was 
increased post year end from c.£5m to c.£8m in August 2023, which indicates the importance of the project and 
the capabilities of our uniquely enabling technology. Such projects are not routine business, and given the success 
in delivering this equipment, management believe this will further enhance the reputation and reach of the Company 
and should help with securing more standard and routine work amongst the other operators involved. 

A major order from Oceaneering for P&A work was completed during the year, with Plexus products delivering 
uniquely enabling methods of safely abandoning old wells. The project was successfully completed with both the 
equipment and the Plexus project team performing well, and the contract delivering significantly more revenue 
than originally anticipated with a final value of c.£850,000. The Plexus products used in this project, together with 
Plexus’ other equipment suitable for P&A work whether from floating vessels or Jack-up rigs, will hopefully see 
an increase in similar project work arising. 

The August 2021 Exact Adjustable Wellhead licence agreement with SLB enabled Plexus’ to re-enter the Jack-up 
exploration rental wellhead market with the proven Exact and Centric wellhead and mudline suspension products. 
Since then, much work has gone on improving the product range and investing capital in building an initial rental 
wellhead inventory. This agreement has now started to generate sales opportunities with two contracts announced 
in October and November 2023, which use Exact wellhead equipment and associated tools. The rental package is 
highly versatile and can be deployed in several applications from Jack-up rigs, including P&A work, exploration 
and appraisal wells, and pre-drilling of production wells, and we are excited about creating this opportunity to

Chairman’s Statement continued

capitalise on the strong reputation that we had built up in the rental exploration wellhead equipment sector prior to 
selling the previous division to TFMC in 2018. 

With Plexus established reputation in Jack-up exploration drilling and mudline suspension systems, alongside 
having knowledge of a number of the legacy wells in the North Sea and worldwide, there is plenty of scope for 
gaining contracts in this growing space over the coming years as they are now being considered for re-entry and 
permanent decommissioning. 

The Company’s 49% investment in its associate company Kincardine Manufacturing Services Limited (“KMS”) 
was deemed to be non-core during the year. As a result, a £0.7m loan arrangement was entered into with Ben van 
Bilderbeek  related  entities  as  announced  in  September  2023,  which  at  the  same  time  granted  two  option 
arrangements whereby the loan can be converted into 70% of Plexus’ 49% shareholding in KMS, with a second 
option for the balance of 30% of the 49% shareholding for an additional £0.3m. Assuming the two options are 
exercised then it is believed that the £1m of additional funds are better deployed within Plexus and to support 
current  growth  plans. Although  KMS  experienced  an  upturn  in  business  following  the  end  of  the  Covid-19 
pandemic, dividends have continued not to be declared which further supported the decision to potentially monetise 
the Plexus KMS shareholding. In the period, Plexus’ share of KMS’ profits led to a credit of £0.18m to the statement 
of comprehensive income. As required under IAS36 an impairment review was undertaken, which concluded that 
no impairment charge was required. At the reporting date the investment in KMS has been reallocated under IFRS 
5 to current asset and has been presented as asset held for sale. 

Plexus’ family of proprietary intellectual property (“IP”) continues to underpin the value and potential of the 
business as evidenced by the ongoing development of products and associated equipment which have enabled the 
c. £8m special project announced during the year, together with innovative P&A solutions contract wins. The IP 
suite consists of a mix of patents, confidential test results and analysis methods, as well as field experience and 
importantly in-depth product know-how which cannot be easily replicated. A key over riding feature of our Plexus 
HG seal designs is their ability to provide leak-proof performance solutions, and this capability was recognised by 
the LSE in 2021 with the accreditation of the Green Economy Mark. Although product patents do expire over time, 
ongoing R&D and proprietary technical innovations continue to protect Plexus and licenced products. In addition, 
new Method Patents for POS-GRIP are ongoing, and are anticipated to give Plexus and its licensees further 
protection of the POS-GRIP method for another 20 years in the UK and worldwide. 

Staff 
On behalf of the Board, I would once again like to thank all our employees for their dedication and hard work 
during the year. Although it was another challenging period as evidenced by the financial results, I am confident 
that the anticipated increase in exploration and production drilling activity which we are already beginning to see 
the  benefits  of  in  the  current  year  will  be  positive  for  our  staff,  and  for  future  employment  opportunities 
within Plexus. 

Outlook 
As governments worldwide look to deliver clean transitions away from hydrocarbons, there has been a tightening 
of climate policies clamping down on O&G practices which is forcing the industry into change. While there has 
undoubtedly been a level of ‘greenwashing,’ ultimately the industry is now moving in the right direction, with new 
sustainable methods and equipment being encouraged, developed and employed to address regulatory demands for 
emissions reductions, particularly in relation to methane. 

In conjunction with these important developments, there is a growing realisation that demand for O&G will, as 
Mike Sommers, the President, and CEO of the American Petroleum Institute, recently wrote in a letter to the 
Financial Times “… remain massive for decades to come”. Furthermore, Mr. Sommers wrote that the “… proper 
focus should therefore be on smart policies that focus on innovations to produce that energy cleaner, safer and more 
efficiently.” We see POS-GRIP as falling clearly into the innovation category. 

7

Plexus Holdings plc Annual Report 2023

Chairman’s Statement continued

We see such developments, including the drive to reduce emissions throughout the supply chain, as opening a new 
chapter in Plexus’ story, particularly as I believe our technology has been several steps ahead of the rest of the 
industry having delivered leak-proof wellhead integrity solutions for over 20 years including its HG wellhead metal 
annular seals. 

With our experienced team of engineers and service personnel based in Aberdeen, and a growing range of products 
that offer multiple benefits and advantages to the O&G industry in terms of improved safety, functionality, and 
cost and time savings, Plexus is well positioned for growth. This includes organic growth in the UK, specialised 
projects in the exploration rental and surface production wellhead sectors, growing P&A activities, and opportunities 
across the wider global market through licencing partnerships such as the SLB licence (recently extended for a 
further six years). 

Specifically in the UK, it is now being recognised that the reliance on imported gas, such as from the US and Qatar 
and the resultant implications for energy security is something that urgently needs addressing. Such considerations 
were brought into sharp focus with the terrorist attack on Israel in October, and it is no coincidence that the CEO 
of Baker Hughes in a recent interview with the Financial Times said that he sees geopolitical risks being at their 
highest level in half a century. However, encouragingly for the North Sea, Andy Brooks the NSTA Director of New 
Ventures recently stated that: “Oil and gas currently meets three-quarters of the UK’s energy needs and projections 
suggest they will both play an important role in the energy mix for decades to come”, a premise that is supported 
by the UK having a significant volume of unsanctioned, discovered resources as well as a wealth of infrastructure. 
For these reasons we believe there are clear growth prospects in the UKCS and the ECS for ‘closer to home’ new 
wells  and  associated  leak-proof  solutions,  as  well  as  opportunities  arising  in  alternative  energy  markets  and 
applications, and Plexus expects to be able to benefit accordingly. 

In closing, I would like to take this opportunity to thank the Board, management team and staff for their continued 
hard work and support over the course of the year. I look forward to working with them all in the year ahead, as we 
focus on delivering on our overriding objective which remains to generate increasing value for all our shareholders.

Strategic Report 

Principal Activity 

The Group markets oil and gas industry wellhead and associated equipment that utilises its patented friction grip 
method of engineering known as POS-GRIP Technology. This involves squeezing one tubular member against 
another within the elastic range to effect gripping between the components and can also set metal-to-metal seals, 
known as “HG”® Seal Technology. This superior method of load support and sealing for wellheads offers several 
important and unique advantages to operators, particularly for HP/HT surface and subsea production applications, 
P&A and special applications, and can include improved technical leak-proof performance, improved integrity of 
metal-to-metal  seals,  significant  installation  time  savings,  reduced  operating  and  maintenance  costs  and 
enhanced safety. 

The Company has developed a range of products based on this technology, and is focused on pursuing surface 
production, P&A, subsea and geothermal wellhead opportunities, as well as connectors and the subsea market. 
Plexus has also re-entered the rental exploration wellhead from Jack-up rigs market through a licence arrangement 
with SLB for Exact adjustable wellhead systems and Centric Mudline tooling and this is the main focus for Plexus 
over the coming years and where Plexus’ past reputation and success in this market can be leveraged. 

In addition to Plexus’ organic activities, the Company pursues licencing opportunities and is supporting SLB, with 
a  POS-GRIP  “HG”  wellhead  licence,  a  non-exclusive  licence  for  the  development  of  conventional  and 
unconventional oil and gas surface production wellheads. SLB is carrying out a testing programme, which is near 
completion, based around its own wellhead designs incorporating the POS-GRIP method; after some delays, SLB 
is expected to commercialise new products developed with the technology in the coming months. 

Business review 
A review of the development and performance during the year consistent with the size and complexity of the 
business together with commentary on future developments including the main trends and factors likely to affect 
the business is given in the Chairman’s Statement on page 6. Where guidelines make reference to the provision of 
key performance indicators, the directors are of the opinion certain financial and non-financial indicators included 
in the highlights on page 1, and the Directors’ Report on page 20 meet this requirement. The Directors have provided 
a description of the principal risks and uncertainties facing the Group on page 14. 

Financial Results 

Statement of Comprehensive Income 
Revenue 
Revenue for the year was £1,487k, a decrease from £2,306k in the previous year. Importantly, deferred income 
includes £3,637k of revenues that will be recognised in the following financial year. 

Margin 
Gross margin increased to 73.1% (compared to 64.7% in the previous year). The increase in margin is largely driven 
by higher margins achieved on rental incomes which make up a higher proportion of sales income in the current 
year compared to the prior year. 

Overhead expenses 
Administrative expenses have decreased compared to the prior year with expenditure of £5,348k (2022: £5,784k). 

Continuing salary and benefit costs remain the largest component of administrative expenses at £2,930k compared 
to £2,863k in the prior year. 

Non-recurring item 
The statement of comprehensive income includes a fair value adjustment on an asset, which was held for sale, of 
£50k, relating to the write-down in a building’s value to its fair value prior to its sale in February 2023. 

Loss Before Tax 
Loss before tax of £4,228k compared to a loss in the prior year of £5,556k.

Adjusted EBITDA 
The Directors use, amongst other things, Adjusted EBITDA on continuing operations as a non-GAAP measure to 
assess the Group’s financial performance. The Directors consider Adjusted EBITDA on continuing operations, 
which approximates the operational cash generated by, or used in the business, to be the most appropriate measure 
of the underlying financial performance of the Group in the period. 

Adjusted EBITDA on continuing operations for the year was a loss of £2,451k, compared to a loss of £2,780k in 
the previous year. Adjusted EBITDA on continuing operations is calculated as follows: 

Operating loss
Add back: 
–Depreciation
–Amortisation

Tax 
The Group shows a total income tax credit of £213k for the year compared to a tax credit of £1,901k for the 
prior year. 

Investments 
In December 2018, Plexus acquired a 49% shareholding in Kincardine Manufacturing Services Limited (“KMS”), 
for a consideration of £735k plus associated legal fees of £50k. At the year-end, a share in profit of associate of 
£182k (2022: profit £111k) has been recognised. No dividends were declared or received. Following an impairment 
review no impairment charge was recognised in the year (2022: £109k). The investment in KMS meets the criteria 
outlined in IFRS 5 and has been reallocated as an asset held for sale. 

EPS 
The Group reports basic loss per share of 4.00p compared to a loss per share of 7.42p in the prior year. 

Statement of Financial Position 
Intangible Assets and Intellectual Property (“IP”) 
The net book value of intangible assets was £8,731k, a decrease of 5% from £9,165k last year. This movement 
represents investment of £516k less the annual amortisation charge of £950k. 

Plexus owns an extensive range of IP which includes many registered patents and trademarks across a number of 
jurisdictions, and actively works to develop and protect new methods and applications. In addition to registered IP, 
Plexus has developed over many years a vast body of specialist know-how in relation to the POS-GRIP friction 
grip method of engineering and related activities. Plexus is also currently pursuing the registration of Method 
Patents, which would further extend the scope of current patent protections. 

The loss in the year and the market capitalisation of the Company being less than the carrying value of the assets 
are indicators of impairment. Following a thorough review, including a discounted cashflow model which has 
included cashflows for 20 years, the Directors have concluded no impairment of IP is required. Therefore, the 
Directors consider the current carrying values to be appropriate.

Strategic Report continued

Research and Development (“R&D”) 
R&D expenditure including patents increased from £447k in 2022 to £516k in 2023. Continued investment in R&D 
demonstrates the Group is protecting, developing, and broadening the range of proprietary POS-GRIP friction-grip 
method of engineering applications, related IP, and Plexus products. 

Tangible Assets 
The net book value of property, plant and equipment including items at the year-end was £1,404k compared to 
£821k last year. Capital expenditure on tangible assets increased to £890k compared to £253k in the prior year. 

Cash and Cash Equivalents 
Net cash at the year-end was £1,449k (cash and cash equivalents of £1,449k with no bank borrowings) compared 
to net cash of £1,882k (cash and cash equivalents of £5,840k less the bank Lombard facility of £3,958k) in the 
prior year, reflecting a net cash outflow for the year of £433k 

The decrease in bank borrowing represents full repayment of the bank Lombard facility which had a balance of 
£3.96m at 30 June 2022. 

It should also be noted that the Group has financial asset investments with a value of £nil (2022: £0.10m) at the 
reporting date. 

The expected future cash inflows and the cash balances held are anticipated to be adequate to meet current on-going 
working capital, capital expenditure, R&D, and project related commitments. 

Dividends 
The Company has not paid any dividends in the year and does not propose to pay a final dividend at this time. 
Whilst the Company remains committed to distributing dividends to its shareholders when appropriate, the Directors 
believe that it is prudent to suspend the payment of dividends in light of the ongoing capital and operational 
requirements of the business. 

Operations 
Progress has continued during the year with the Company’s strategy to build a portfolio of revenue streams based 
on its POS-GRIP technology and associated products and services. 

The Company’s primary focus continues to be the marketing of its POS-GRIP-enabled products and supporting 
licensees  of  the  technology,  as  well  as  the  re-entry  to  the  rental  exploration  market  with  its  non-POS-GRIP 
equipment designs. Plexus continues to supply surface production wellheads and is also pursuing supplemental 
business opportunities relating to well abandonment and decommissioning, which are anticipated to be growth 
areas as the world’s older producing oil and gas fields, such as in the North Sea, come to the end of their lives. 

Plexus continued to invest in R&D during the year, with significant focus on optimising the Exact rental exploration 
wellhead product range for the current market, and also to complete product development and testing required for 
the Oceaneering decommissioning work and the forthcoming specialised project. R&D remains an important 
operational activity and further develops the value of our IP and ability to extend the range of applications of POS-
GRIP technology. Innovation in the oil and gas industry continues to be an essential part of developing both cost 
saving initiatives and ever safer drilling methods, particularly in relation to greener leak-proof technologies and 
equipment, and the Board is confident that Plexus can continue to play an important role in delivering such solutions 
whilst raising wellhead standards to a level that conventional technology cannot reach, such as passing test standards 
equivalent to those used for premium couplings. 

Staff  at  the  end  of  June  2023  (excluding  non-executive  directors)  comprised  of  36  employees,  including 
1 international employee, with a weighted average total of 36 in the current year and 35 in the prior year. 

Staff development remains a significant focus with the completion of a comprehensive evaluation and revision of 
the in-house training modules to ensure they continue to provide the necessary underpinning knowledge and skills 
which is required of those fulfilling technical roles. 

The  Company  continues  to  maintain  the  OPITO  accreditation  for  its  competency  management  system,  with 
continual  developments  and  improvements  to  the  process,  ensuring  a  robust  assessment  of  employees  in 
safety-critical roles. 

11

Plexus Holdings plc Annual Report 2023

Strategic Report continued

Health and Safety continues to be a pivotal part of the business and remains at the centre of everything we do. 
Plexus remains fully committed to continually improving safety standards and the safety culture across the business. 
This is reflected in the business being once again lost time injury (“LTI”) free this year. Plexus has now passed its 
eighth anniversary of this milestone in September 2023. 

Plexus continues to comply with the requirements of the API Q1/ISO 9001 and ISO 45001 standards to include the 
retention of both API 6A and 17D Licences. These accreditations demonstrate Plexus’ capability and determination 
to operate under the highest standards. Post period end API conducted an audit with 1 minor finding, resulting in 
Plexus retaining their accreditation. 

The IT Department provides technology leadership for Plexus, including governance, information security, software 
development and expertise in deploying modern information technologies to improve company efficiency. Plexus 
has continued to develop its in-house systems to ensure the Group is able to react swiftly to changing market 
requirements, and constantly review the Company’s IT infrastructure. No significant IT infrastructure projects were 
undertaken in the year. 

Strategy and Future Developments 

Technology 
Plexus’ proprietary POS-GRIP technology involves applying compressive force to the outside of a wellhead or 
pipe, to flex it inwards. As the bore of the vessel moves inwards, it makes contact with an inner pipe (or hanger) 
on the inside. Sufficient contact force is generated to hold the inner member in place through friction between the 
two components, whilst at the same time creating a superior metal-to-metal seal. There are numerous advantages 
associated with being able to connect two tubular members without the need for threads or rotation. The Company’s 
strategy is primarily focused on delivering the highest standard of wellhead and associated Plexus products design 
for the upstream oil and gas markets around the world. These have already proved to be uniquely advantageous in 
terms of safety features, operational efficiency, and cost savings, especially for HP/HT applications. The Company 
is now focused on replicating this past success in the exploration drilling from Jack-up rigs sector, as well as other 
wellhead  and  related  markets  including  surface  production,  subsea,  plug  &  abandonment,  gas  storage  and 
geothermal, together with other initiatives such as a POS-GRIP Crown Plugs and POS-GRIP Lateral Trees. Plexus’ 
re-entry  into  the  exploration  rental  wellhead  for  the  Jack-up  drilling  market  will  be  built  on  non-POS-GRIP 
technology but with specific benefits and features including “through the BOP” safety features. 

POS-GRIP wellhead designs deliver many advantages over conventional “slip and seal” and “mandrel hanger” 
wellhead technologies for surface exploration and land and platform production applications. These include larger 
metal-to-metal  “HG”  seal  contact  areas,  virtual  elimination  of  movement  between  parts,  fewer  components, 
simplified design and assembly, enhanced corrosion resistance, simpler manufacture, long term integrity, annulus 
management, and reduced installation and maintenance costs. Plexus’ HG seals offer leak preventative capabilities 
for the life of the well which is a key consideration when addressing Net Zero and ESG responsibilities, especially 
where methane emissions are concerned. 

Plexus’ POS-GRIP enabled product suite also includes the innovative Python® Subsea Wellhead as well as the 
POS-SET Connector® for use in the growing decommissioning market. We believe the Python subsea wellhead 
has tremendous potential as it can eliminate the need for wear bushings, pack-offs, lock-rings, and lockdown sleeves, 
whilst delivering instant rigid lock-down in all directions, and is fully reversible for ease of workover, side-tracking, 
or abandonment. These design simplifications and features not only reduce the risk of installation problems and 
safety issues, they also significantly reduce installation time and the number of trips that are needed such that it 
has been independently estimated that over ten days of time savings per well can be achieved in deep-water under 
certain conditions which, depending on water depth, Plexus estimates could result in a saving of over $10m for the 
operator. The POS-SET Connector, which is designed to re-connect to bare conductor pipe for well re-entry or 
permanent abandonment operations, creates a solid connection with reliable sealing directly against the pipe, and 
retains bend and load capabilities at 80% of pipe strength. The Directors believe that such features mean that Plexus’ 
wellhead equipment sets and delivers a superior standard. Apart from the operational time savings and related safety 
benefits, at an engineering level the Company has demonstrated that its technology can raise and even exceed the 
integrity of wellhead testing and sealing to that of premium couplings, which supports its claim that wellheads no 
longer need to be the weak link in the well architecture chain.

POS-GRIP friction-grip technology has wide ranging applications both within and outside the oil and gas industry. 
As POS-GRIP is a method of engineering as opposed to a product in its own right, there is an opportunity for the 
technology to improve the performance of conventional products. The Company will look to integrate POS-GRIP 
so that the range of benefits, together with “HG” metal-to-metal sealing can be realised organically or in conjunction 
with partners, including licensees. In line with this strategy, in November 2020 Plexus entered into a licence 
agreement with Cameron International Limited, which grants the Schlumberger (‘SLB’) group company a non-
exclusive licence to use the POS-GRIP and HG® metal-to-metal seal method of wellhead engineering for the 
development of conventional and unconventional oil and gas surface production wellheads. The scope of this licence 
was further expanded in December 2021, and subsequently in May 2023 was extended for a further period of six 
years. SLB continues to make good progress with the engineering and testing programme of their new wellhead 
design which will incorporate Plexus technology. The programme has taken longer than originally anticipated, and 
therefore marketing and sales activity by SLB to its customers should begin in the first half of 2024 calendar year. 

In addition to POS-GRIP Technology, Plexus is now re-entering the Jack-up exploration rental wellhead market 
with SLB’s Exact and Centric wellhead and mudline suspension products. These products are tried and tested, and 
well suited to the exploration market as they are “through the BOP” products which deliver crucial time savings 
and safety benefits over conventional wellhead products. As the exploration market rebounds in the North Sea, 
especially following the recent issue of new licence, as well as internationally, these products, combined with 
Plexus’ experience and reputation in this sector means that we are well placed to win a significant share of the 
work now beginning to be planned, and where the Company is seeing a number of contract opportunities arise. 

Business Model and Markets 
The Company is proprietary technology driven and its extensive patent protected IP and many years’ worth of 
specialist  know-how  has  been  successfully  deployed  in  hundreds  of  wells  around  the  world.  Its  superior 
performance, safety and operational advantages led to the Company becoming established initially as a leading 
equipment and services provider to the niche Jack-up exploration rental wellhead market. The Directors believe 
that this success can over time be replicated and extended to the wider and much larger energy sectors including 
surface production, subsea, geothermal, and fracking applications based on its POS-GRIP technology. In addition 
to this there is a surge in interest in subsurface storage wells for gas, CO2, and hydrogen, for which POS-GRIP 
technology is also ideally placed to address the need for leak-proof equipment designs. 

Plexus  has  a  good  reputation  for  offering  the  agility  and  customer  focus  required  to  succeed  in  the  Jack-up 
exploration rental wellhead market, and so the licence agreement with SLB to allow Plexus to re-enter this market 
with field proven products is welcome and is anticipated to see an addition to revenues as global exploration activity 
increases. Importantly SLB are also referring potential order enquiries to Plexus which is a further route to market. 

An emerging market sector where Plexus’ technology is beginning to gain traction is ‘special solutions’ where the 
Company’s innovative IP and product designs and applications can prove uniquely beneficial. A key special project 
contract of this nature was announced in March 2023 with a value of c. £5m and was subsequently increased by a 
further c. £3m in August 2023, and may increase further. 

Strategy 
Plexus’ long-term goal is to establish POS-GRIP technology as a new industry standard for wellhead and metal 
sealing designs, whilst continuing to develop new Plexus products, which can also offer multiple benefits and 
advantages to the industry in terms of improved safety, functionality, and cost and time savings. An example of 
such extensions for POS-GRIP technology is the Company’s connector technology, which is ideal for high integrity, 
low fatigue applications. The Directors believe wellhead connectors, riser connectors, subsea jumper connectors, 
pipeline connectors, tether tensioners and even vessel mooring connectors can all benefit from the simplicity of 
the POS-GRIP method of engineering. 

The Company has taken on the SLB Exact adjustable wellhead and Centric mudline suspension products. It has 
been  necessary  to  invest  time  and  money  into  building  an  initial  rental  inventory  to  create  capacity  to  meet 
anticipated demand. This has resulted in initial orders for P&A and decommissioning work associated with this 
equipment. We expect that the increase in activity and revenue from this business will be positive and will also 
allow Plexus to re-engage with customers at the exploration stage, which then has the potential to lead to follow 
on production and subsea opportunities. 

13

Plexus Holdings plc Annual Report 2023

Strategic Report continued

As the world and the oil and gas industry strives to implement a range of ESG compliant initiatives, particularly in 
relation to achieving net zero, Plexus believes that its technology can make a valuable contribution in terms of its 
leak-proof sealing capabilities, and its ‘through the BOP’ wellhead designs. 

Key Performance Indicators 

The Directors monitor the performance of the Group by reference to certain financial and non-financial key 
performance indicators. The financial indicators include revenue, adjusted EBITDA, profit and loss, earnings per 
share, cash balances, and working capital resources and requirements. The analysis of these is included in the 
financial results section of this report. Non-financial indicators include Health and Safety statistics, R&D activity, 
equipment utilisation rates, geographical diversity of revenues and customers, the level of ongoing customer interest 
and support, geopolitical considerations such as emissions concerns and awareness, effectiveness of various research 
and development initiatives, for example, in relation to new patent activity and inventions, and appropriate employee 
headcount numbers and turnover rates. The non-financial key performance indicators are included within the 
strategic report on page 9. 

Principal Risks and Risk Management 

There are a number of potential risks and uncertainties that could have an impact on the Group’s performance 
which include the following. 

(a) Political, legal, and environmental risks 

Plexus aims to participate in a global market where the exploration and production of oil and gas reserves, 
and even the access to those reserves can be adversely impacted by changes in political, operational, and 
environmental circumstances. This has for example been evidenced by the impact of the war in Ukraine, 
ongoing Russian sanctions, and the recent terrorist activity against Israel. The current global political and 
environmental landscape, particularly in relation to climate change issues and net zero goals, and the relentless 
plan  to  move  away  from  hydrocarbons  to,  for  example  renewables,  continues  to  demonstrate  how  any 
combination of such factors can generate risks and uncertainties that can undermine commercial opportunities 
and trading conditions. Some risks are of course unforeseen, and one such significant risk took the form of 
the global pandemic caused by COVID-19 which materialised in 2020 and where its social and economic 
impact continues to be felt today. Although Plexus has taken all reasonable steps to mitigate the effects of 
this risk, both economic and to the health and well-being of our employees, customers, and suppliers by 
complying with legislation and taking measures to ensure business continuity, the negative impact has clearly 
been felt. Such risks also extend to legal and regulatory issues, and it is important to understand that these 
can change at short notice. For example, ongoing and future changes to oil and gas industry windfall taxes 
may have an adverse impact on investment levels, as of course does a country’s decision-making process in 
relation to granting new exploration and production drilling opportunities. To help address and balance such 
risks, the Group where possible seeks to broaden its geographic footprint and customer base, as well as actively 
looking to forge commercial relationships with large industry players, and potential licencees. 

The Company continues to closely monitor the potential impact and risks of the UK’s exit (“Brexit”) from 
the European Union (“EU”). This includes assessing and monitoring the potential impact of the introduction 
of trade tariffs and the potential supply chain disruption that could result from increased customs checks at 
borders and related matters which are being indicated for 2024. Plexus has an IP-led business model, which 
provides it with operational flexibility and the ability to respond to and mitigate some of the potential impacts 
of the different scenarios resulting from the UK’s exit from the EU. In the meantime, Plexus has amongst 
other activities obtained an Economic Operator Registration and Identification (“EORI”) number to enable 
the Company to continue to import and export with the EU. 

(b) Oil and Gas Sector Trends 

It is readily understood that the world continues to move away from coal as part of the COP21 as well as the 
COP26 and COP 27 pronouncements, together with other climate change objectives in relation to the ongoing 
need to urgently reduce CO2 and CH4 (methane) emissions. Importantly legislation is now beginning to be 
introduced which can impose large fines on companies that do not control their emissions, particularly methane 
and such developments logically suggest that E&P operators should be more interested than ever before in 
preventative leak solutions rather than temporary ‘cures.’ However, the commercial and environmental 
dynamics between traditional hydrocarbons in terms of coal, oil and gas is not the only trend to consider. 

Plexus Holdings plc Annual Report 2023

14

Strategic Report continued

New technologies, particularly in relation to renewables such as wind and solar, alternative energies and 
developments such as the increasing use of electric vehicles and corresponding improvements in battery 
storage life, and wave energy, could all in the future prove very disruptive to the traditional oil and gas industry 
and the corresponding demand for exploration and production equipment and services. However, it is also 
now clearly recognised that the world will continue to need hydrocarbons as an energy and materials source, 
and in particular gas for decades to come, and indeed currently global demand for hydrocarbons is forecast 
to continue to grow for the foreseeable future. It should be noted that the adverse climate change impact of 
methane compared to CO2 is now better understood by environmentalists, regulators and the oil and gas 
industry and that it is essential that methane wellhead leaks are prevented whenever and wherever possible. 
The impending Methane Emissions Reduction Act in the US and similar legislation being progressed in 
Europe demonstrate regulations are increasingly becoming more stringent. 

(c) Technology 

Having originally proved the superior qualities of POS-GRIP technology within the Jack-up rental wellhead 
exploration market which culminated in the sale of that business to FMC Technologies Limited, a subsidiary 
of TechnipFMC (Paris:FTI, NYSE:FTI) (jointly “TFMC”), in early 2018, the Company has focused on 
establishing its technology and equipment in other markets including surface production wellheads, subsea 
and de-commissioning, both organically and through licence partners. Plexus has since re-entered the rental 
exploration wellhead market with non-POS-GRIP designed equipment following a licence agreement with 
SLB in August 2021. Further, in November 2020 Plexus entered into a licence agreement with Cameron 
International Limited, which grants the SLB group company a non-exclusive licence to use the POS-GRIP 
and HG® metal-to-metal seal method of wellhead engineering for the development of conventional and 
unconventional oil and gas surface production wellheads. The scope of this licence was further expanded in 
December 2021, and was subsequently extended by a further six years in May 2023. 

(d) Competitive risk 

The Group operates in highly competitive markets and often competes directly with large multi-national 
corporations who have greater resources and are more established, and who are more resilient to extended 
adverse trading conditions. This risk has become more concentrated over recent years as a result of the large 
oil service company competitors and the target customer base becoming even larger and more influential 
through a series of mergers and acquisitions. The major oil service and equipment company consolidations 
have therefore magnified such issues as competitors reduce in number but increase in size, influence, and 
reach. Unforeseen product innovation or technical advances by competitors could adversely affect the Group, 
and lead to a slower take up of the Group’s proprietary technology. To mitigate this risk, Plexus has an active 
R&D programme, and maintains an extensive suite of patents and trademarks, and actively continues to 
develop and improve its IP, including adding to its existing extensive ‘know-how’ to ensure that it continues 
to be able to offer unique superior wellhead design solutions. 

(e) Operational 

Plexus, like many other oil service companies, had to make significant reductions in its workforce numbers 
over the past few years as a result of a volatile oil price and market challenges and a corresponding reduction 
in drilling activity and related levels of capex spend. These adverse trading conditions were magnified since 
early 2020 by the Covid-19 pandemic, which in turn coincided with an acceleration in the world’s clearly 
expressed desire to reduce its dependence on hydrocarbons, particularly following the start of the war in 
Ukraine in February 2022. However, there are now encouraging signs of a global pick up in drilling activity, 
although it is possible that the industry and Plexus could experience difficulties in rehiring past or new 
employees and which could deprive Plexus of the key personnel necessary for expanding operational activities, 
as well as R&D initiatives, at the rate that may be required. To help mitigate this risk, Plexus has developed 
effective recruitment and training procedures, which combined with the appeal of working in a company with 
unique technology and engineering solutions will hopefully help to mitigate such risks. In addition, there are 
signs that certain pressure groups such as Just Stop Oil and Extinction Rebellion are increasing their level of 
activity, and this may also impact on oil and gas investment and drilling activities, at least in the West.

(f) Going Concern, liquidity, and finance requirements 

In  an  economic  and  global  geopolitical  climate  that  in  many  ways  remains  uncertain,  it  has  become 
increasingly possible for potential sources of finance to be closed to businesses for a variety of reasons that 
have not historically been an issue. Some of these may even relate to the lender itself in terms of its own 
capital ratios and lending capacity where financial pressures and constraints can apply. Also, Plexus’ smaller 
market cap can be a negative factor if consideration is given to raising additional funds in the public markets. 
Furthermore, a number of large and influential institutions have actively divested oil and gas investments and 
declared that further investments and funding will not be made available for oil and gas projects as a result 
of climate change concerns and as part of the move to net zero. Positively however there are signs that the 
capital markets are once again opening up to oil services companies should raising capital be necessary. The 
Group undertakes cashflow forecasting throughout the year to ensure the going-concern assumption is still 
appropriate. The recent raising of funds from convertible loans, and the sale of Treasury shares is an example 
of this and helps to ensure the Group has adequate working capital headroom to see it through the next 
12 months. However as disclosed in note 1b the group is reliant on raising additional funding, an event that 
was indicated at the time the convertible loan arrangements were entered into in October 2022, and there can 
be no certainty regarding the timing and quantum of future funding and therefore this indicates a material 
uncertainty which may cast significant doubt regarding the Group’s ability to continue as a going concern. 

(g) Credit 

The main credit risk is attributable to trade receivables. Where the Group’s customers are large international 
oil and gas companies the risk of non-payment is significantly reduced, and therefore is more likely to be 
related to client satisfaction and potentially in a volatile world trade sanction issue. Where smaller independent 
oil and gas companies are concerned, credit risk can be a factor. Customer payments can potentially involve 
extended periods of time especially from countries where exchange control regulations can delay the transfer 
of funds outside those countries. As Plexus begins to establish international licensee relationships there may 
be instances whereby certain capital and royalty payments could be due some way into the future and as such 
greater credit risk than exists under normal payment terms could apply. The Group’s exposure to credit risk 
is monitored continuously, and to date its collections record has been extremely reliable. 

(h) Risk assessment 

The Board has established an on-going process for identifying, evaluating, and managing the more significant 
risk areas faced by the Group. One of the Board’s control documents is a detailed “Risks assessment & 
management document,” which categorises risks in terms of – business (including IT), compliance, finance, 
cash, debtors, fixed assets, other debtors/prepayments, creditors, legal, and personnel. These risks are assessed 
and updated as and when appropriate and can be associated with a variety of internal and external sources 
including  regulatory  requirements,  disruption  to  information  systems  including  cyber-crime,  control 
breakdowns and social, ethical, environmental and health and safety issues. 

(i) COVID-19 

Although the regulations around COVID-19 were relaxed in 2022, Plexus continues to place the health and 
safety of its employees as its highest priority and in line with this has implemented various protocols. The 
Board continuously monitors the situation, should Government guidance change.

Section 172 Statement  

This section serves as the section 172 statement and should be read in conjunction with the full Strategic Report 
and the Corporate Governance Report. Section 172 of the Companies Act 2006 requires directors to take into 
consideration the interests of stakeholders in their decision making. The Directors continue to have regard to the 
interests of the Company’s employees and other stakeholders, including shareholders, customers and suppliers, 
Licence Partners and the community and environment, through positive engagement and when making decisions. 
Acting in good faith and fairly between members, the Directors consider what is most likely to promote the success 
of the Company for its members in the long term and to protect the reputation of the Company. 

Shareholders 
Plexus seeks to develop an investor base of long-term shareholders that are aligned to our strategy, whether 
institutional or private retail investors. By communicating our strategy and objectives, we seek to maintain continued 
support from our investor base. Such opportunities have been made more challenging by the financial performance 
of Plexus over the past few years, and the resultant decline in the size of the market cap of the business. However, 
now that positive news flow is beginning to be generated the Directors believe that a fresh approach can be made 
to the investment community both to existing and new potential shareholders in conjunction with its advisors. 
Important issues include financial stability and the strength of the balance sheet, and protecting and strengthening 
the value of our intellectual property. Engagement with shareholders is a key element to this objective and methods 
of engagement are detailed in the Corporate Governance Report on pages 23 to 35, although over the past years, 
as a result of the Covid pandemic’s impact on working practices, such interactions in common with many other 
businesses have lessened. Encouragingly there are signs that “normal” interaction levels will begin to reassert 
themselves.  During  the  year,  the  Finance  Director  supported  by  other  members  of  the  executive  team,  the 
Company’s  broker,  and  the  Investor  Relations  advisor,  engaged  where  possible  with  investors  by  email, 
presentations, direct conversations, and ad-hoc meetings. The Company also continues to update its website to 
provide investors and other stakeholders with access to information about the Company. The website includes 
details of the LSE “Green Economy Mark” status, which was awarded in July 2021, and associated NetZero 
commentary. During the year, several key decisions were made by the Board, including the raising of funds through 
the issue of £1.55m of Convertible Loan Notes; the sale of a leasehold interest along with associated leasehold 
liabilities  for  £1m  cash  and  post  year  the  entering  into  loan  agreements  with  a  total  of  £700k. All  of  these 
fund-raising related decisions are aimed at increasing shareholder value. 

Employees 
The Group’s UK staff are engaged by the Company’s subsidiary Plexus Ocean Systems Limited based in Aberdeen, 
Scotland. Being a relatively small company with just over 30 employees largely operating in one location, there is 
a high level of visibility regarding employee engagement and satisfaction. The Company is engaged with a specialist 
firm of benefits advisers who can offer a comprehensive service to employees as well as to the Company. The 
Company consults with employees on matters of competency, training, and health and safety as detailed in the 
Corporate Governance Report on pages 23 to 35. During the year, the Company successfully achieved eight 
continuous years with no Lost Time Incidents (LTI’s) and this successful safety culture has continued beyond that 
anniversary to the date of writing. 

Customers and Suppliers 
The Company is committed to acting ethically and with integrity in all business dealings and relationships. Fostering 
good business relationships with key stakeholders including customers and suppliers is important to the Company’s 
success. The Board seeks to implement and enforce effective systems and controls to ensure its supply chain is 
maintaining the highest standard of business conduct in line with best practice including in relation to anti-bribery 
and modern slavery. 

Licence Partners 
The  Company  engages  with  Licence  Partners  in  a  way  that  follows  the  same  principles  as  those  applied  to 
relationships with other customers and suppliers. Additionally, the Company engages with its Licence Partners to 
support their efforts to achieve commercial success by holding as and when required technical workshops, technical 
training, and data transfer. Following the announcement in November 2020 of entering into a non-exclusive surface 

17

Plexus Holdings plc Annual Report 2023

Strategic Report continued

wellhead licencing agreement with Cameron (SLB) and the extension of this agreement in December 2021, regular 
Teams meetings and occasional face to face meetings have been held as part of the process of transferring Plexus’ 
relevant IP so that Cameron can design and develop its own low-cost wellhead with POS-GRIP technology inside. 
In May 2023 SLB exercised its option to extend its non-exclusive licence agreement with Plexus for an additional 
six years effective from November 2023. 

Community and Environment 
The Company has minimal environmental impact in the localities in which it operates. This clearly helps the 
Company meet its corporate objectives in this regard but is never taken for granted. In the year under review, the 
Company met its target for waste management and in general continues to operate in a manner that is open, honest, 
and socially responsible.

Research and development 
The Group actively engages in various on-going research and development initiatives designed to expand and 
develop the range of commercial applications deriving from its proprietary technology, including an in-house R&D 
engineering team. For the year, R&D expenditure including capitalised wage and salary costs totalled £0.52m 
(2022: £0.45m). 

Results and dividends 
The results for the year show a loss before taxation of £4.23m (2022: loss £5.56m) and is set out on page 47. The 
directors do not recommend the payment of a final dividend for the year ended 30 June 2023 (2022: nil). 

Corporate governance 
This is the subject of a separate report set out on page 23. This is an expanded report following the adoption of the 
Quoted Companies Alliance Corporate Governance Code in line with the AIM Rules of the London Stock Exchange 
that require all AIM-listed companies to adopt a recognised corporate governance code against which they must 
comply or explain why there is any divergence in complying with that code. 

Related party transactions 
Details of related party transactions are set out in Note 29 in the financial statements. 

Financial instruments and risk management 
The Group maintains a commercial objective of contracting in sterling whenever possible. In circumstances where 
this is not possible, the Group converts foreign currency balances into sterling on receipt so far as they will not be 
used for future payments in the foreign currency. The Group maintains risk management policies which are set out 
in more detail in Note 25 to the accounts. 

Streamlined Energy and Carbon Reporting Summary 
The Group is below the threshold to report on its Greenhouse gas emissions and energy consumption. 

Subsequent events 
In September 2023 Plexus entered into a £200,000 loan with the Company’s CEO, Ben van Bilderbeek, and a 
£500,000 loan with Plexus Property International Limited (“PPI”), a company owned and controlled by OFM 
Limited a company in turn controlled by the van Bilderbeek family and related trusts. The Loans accrue interest at 
a rate of 8 per cent per annum and the balance, plus any interest accrued, is repayable after 12 months. Alongside 
the loan agreements, the Company has also entered into Primary and Secondary call option agreements with Ben 
van Bilderbeek and PPI. These option agreements provide the Lenders with the right to exercise an option to have 
their portion of the Loans repaid in shares owned by Plexus Ocean Systems Limited in Kincardine Manufacturing 
Services Limited, a precision engineering company in which Plexus holds a 49% interest following an investment 
in December 2018 

In October 2023 Plexus sold 2,750,000 of the shares held in treasury at an average price of 19.97 pence per share, 
which raised gross proceeds of £549,230. 

Going concern 
The directors, having made appropriate enquiries, believe that the Group will continue in operational existence for 
the foreseeable future and it is appropriate to continue to adopt the going concern basis in preparing the financial 
statements. As disclosed in note 1 (b) the group is reliant on raising additional funding, an event that was indicated 
at the time the convertible loan arrangements were entered into in October 2022 and there can be no certainty

Corporate Governance

Chairman’s Introduction 

Plexus’ long-term goal is to establish POS-GRIP friction grip technology as a superior industry standard for wellhead 
and metal sealing systems, whilst continuing to develop a range of POS-GRIP based products, which can also offer 
multiple benefits and advantages to the industry in terms of improved safety, functionality, and cost and time 
savings. Key to this is the Board working to ensure the Company is managed for the long-term benefit of all 
shareholders, by effective and efficient decision making which may only happen where a culture of corporate 
governance is engendered. 

Plexus remains committed to a culture built on its objectives of developing the products described above for the 
stated purposes, and its strategic aims and business model are consistent with that culture. The Board promotes a 
healthy culture within the business by actively encouraging a collegiate manner of working amongst all staff. It 
monitors and assesses the culture from time to time through contact as appropriate with staff at all levels which it 
is able to do because of the relatively small number of staff Plexus employs. The Board also has the benefit if 
required of feedback from the annual personal development appraisal reviews which all staff are required to 
complete. 

The Board has adopted the Quoted Companies Alliance Corporate Governance Code in line with the AIM Rules 
of the London Stock Exchange that require all AIM companies to adopt a recognised corporate governance code 
against which they must comply or explain why there is any divergence in complying with that code. The Board 
considers Plexus complies in all material respects with the principles of the QCA Corporate Governance Code 
although  as  indicated  in  the  summary  below,  the  adoption  of  certain  informal  procedures  rather  than  formal 
procedures to reflect the size of the Company and the composition of the Board, does not constitute full compliance 
in all respects. The disclosures made within the principles comprising the QCA Corporate Governance Code are 
anticipated to evolve over time. 

Principle 1: Establish a strategy and business model which promotes long-term value for shareholders 
Plexus has developed a range of products and applications based on its patent-protected POS-GRIP friction-grip 
method of wellhead engineering. The Company is focused on commercialising this technology and equipment in 
a range of sectors including surface production wellheads, subsea and de-commissioning, both organically and 
through licence partners. In line with this strategy, in November 2020 Plexus entered into a licence agreement with 
Cameron  International  Limited,  which  granted  the  SLB  group  company  a  non-exclusive  licence  to  use  the 
POS-GRIP and HG metal-to-metal seal method of wellhead engineering for the development of conventional and 
unconventional oil and gas surface wellheads. The scope of this licence was extended in December 2021, and in 
May 2023 SLB exercised its option to extend the licence agreement for an additional six years effective from 
November 2023. 

In August 2021 Plexus took the opportunity to re-enter the exploration rental wellhead market from Jack-up rigs 
market which it had previously been successful in before selling the division (with the exception of Russia and the 
CIS) to TechnipFMC in February 2018. This activity is being built around non-POS-GRIP technology with bespoke 
Plexus design features, and “through the BOP” for enhanced safety. Shortly after the beginning of the conflict in 
Ukraine, all licensed activities in Russia and the CIS were suspended indefinitely. 

Since it was established, Plexus has focused on being an innovative, IP-led company mainly built around its 
proprietary POS-GRIP technology. POS-GRIP was designed to address limitations associated with conventional 
wellhead technology particularly regarding long-term metal sealing and has subsequently raised standards for 
HP/HT wellhead applications. POS-GRIP enables Plexus to provide operators with superior solutions, offering 
unique safety and operational advantages, while at the same time delivering significant time and cost savings on 
the surface and, the Board in due course anticipates moving into the subsea sector. Plexus has successfully raised 
wellhead test standards to equal or exceed those of premium couplings and there are numerous applications and 
products beyond Jack-up exploration drilling which the Board believes could benefit from the POS-GRIP method 
of engineering now and in the future. 

The Company has, over many years, invested, and indeed continues to invest in R&D and IP development and 
areas and applications outside of Jack-up exploration wellheads, including in addition to surface production and 
subsea wellhead equipment, proprietary connector technology. This suite of new products and applications has 
grown significantly and includes: the Python Subsea Wellhead (a new standard for subsea wellheads – where a JIP 
was supported by BG, Royal Dutch Shell, Wintershall, Maersk, Total, Tullow Oil, Eni, Senergy, and Oil States 

23

Plexus Holdings plc Annual Report 2023

Corporate Governance continued

Industries  Inc);  the  development  of  the  POS-SET  Connector®  (“POS-SET”)  product  for  the  growing 
de-commissioning and abandonment market; development of HP/HT dual marine barrier risers to provide an 
efficient, safe and cost-effective solution for use on Jack-up rigs; an innovative HP/HT Tie-Back connector product 
and a Well Tree product. Plexus is also assessing opportunities in geothermal drilling and for gas storage. 

Prior to the sale of the POS-GRIP Jack-up rental wellhead business to TFMC, Plexus successfully expanded its 
focus as part of its strategy to raise the awareness of its superior technology with contracts extending to Asia, 
Australia, China, Egypt, Middle East, Russia, and West Africa from the UKCS, and in the process became a supplier 
to a wide customer base, including blue-chip customers. An Asian business hub was established to increase the 
supply of POS-GRIP wellhead equipment and services to the Australian, Brunei, Indonesian, Malaysian, Thai, and 
Singaporean oil and gas exploration and production markets. Strategic licence agreements were pursued, including 
in 2016 with Gusar, and Konar, two independent Russian oil and gas equipment manufacturers, for the rental, 
manufacture, and servicing of Plexus’ Jack-up drilling exploration wellhead equipment into the Russian Federation 
and the other CIS states’ oil and gas markets. The licencing relationship with Gusar is outside of the business 
activities that were sold to TFMC. However, as noted above, all activities in Russia and the CIS have been suspended 
indefinitely following the start of the war in Ukraine. 

The Company continues to face a number of key challenges although the combination, nature, and scale of these 
continues to ebb and flow. For example, although the previously volatile oil price had been stabilising to a degree 
it is once again facing a period of uncertainty following recent terrorist activity against the State of Israel. Should 
there be further polarization between the West, and Russia and China in relation to energy supplies it is likely that 
additional exploration and production expenditure will be necessary. In addition it must not be forgotten that the 
ongoing conflict in Ukraine continues to cause Russian oil and gas supply interruptions and sanction driven 
constraints which have recently been extended by the US, and the need and desire to replace Russian hydrocarbons 
continues to gain pace whether through alternative means such as LNG, or through renewables and a fast growing 
interest in nuclear power, especially the possibilities of mini nuclear reactors. 

Plexus’ long-term goal is to establish POS-GRIP technology as a superior industry standard for wellhead and 
leak-free metal sealing designs, whilst continuing to develop new products, which can also offer multiple benefits 
and advantages to the industry in terms of improved safety, functionality, and cost and time savings. An example 
of such extensions for POS-GRIP technology is the Company’s connector technology, which is ideal for high 
integrity, low fatigue applications. The Directors believe wellhead connectors, riser connectors, subsea jumper 
connectors, pipeline connectors, tether tensioners and even vessel mooring connectors can all benefit from the 
simplicity of the POS-GRIP method of engineering. 

Production wellheads are required for the entire field life, and the size of the market for production wellheads is 
many times that of Jack-up exploration wells. At the same time as the exploration and production market recovers 
there is a major shift from coal and even oil to cleaner natural gas production, whether pipeline gas or LNG. This 
should be a positive trend for Plexus as it is widely recognised that gas leaks are very damaging to the atmosphere 
in terms of climate change, particularly with regard to the impact of methane on the environment, and therefore 
the need for superior and reliable long-term metal-to-metal leak-free sealing technology and integrity has never 
been greater. 

In terms of performance, the Board monitors the Group by reference to certain financial and non-financial key 
performance indicators. The financial indicators include revenue and margins, overhead expenses, EBITDA, profit 
and loss, earnings per share and both fixed and working capital resources and requirements. Non-financial indicators 
include  Health  and  Safety  statistics,  employee  welfare,  geographical  diversity  of  revenues  and  customers, 
geopolitical considerations, effectiveness of various research and development initiatives, for example, in relation 
to new patent activity and inventions and appropriate employee headcount numbers and turnover rates. The key 
performance indicators of the Group are currently focused on both financial and non-financial key performance 
indicators such as cash resources, research and development activities and commercialization objectives, including 
licencing initiatives. Over time, as financial key performance indicators such as revenue streams become more 
established it may be that for example licence income rather than sales revenue becomes more relevant. 

2: Seek to understand and meet shareholder needs and expectations 
The Company remains committed to dialogue and communications with its shareholders to ensure that its strategy, 
business  model  and  performance  are  understood  by  the  market,  particularly  in  relation  to  the  capabilities  of 
Company’s proprietary IP and special solutions which Plexus believes are becoming more widely recognised. 
Understanding what analysts and investors think about Plexus, and helping these audiences understand our business, 
is part of moving our business forward and we welcome dialogue with the market with the support of our broker 

Plexus Holdings plc Annual Report 2023

24

Corporate Governance continued

Cavendish Capital Markets Limited (formerly Cenkos Securities plc) and Investor Relations advisors St Brides 
Partners.  Such  communications  when  and  where  appropriate  include  investor  presentations,  RNS  updates, 
responding to specific phone calls and emails, ad hoc meetings as required and results period meetings, and our 
regular reporting. The Company also maintains a dedicated email address which investors can use to contact the 
Company  which  is  displayed  on  the  website  together  with  the  Company’s  address  and  phone  number  – 
http://www.plexusplc.com/contact-us 

As the Company is too small to have a dedicated investor relations department, the Finance Director is primarily 
responsible for reviewing communications received from members, and in conjunction as necessary with the CEO 
and if appropriate the Board, before determining the most appropriate response. 

Responses to shareholders are typically sent by email or letter in a timely manner. 

Private shareholders 
Our AGM is the main forum for dialogue with private shareholders. The Notice of Meeting is sent to shareholders 
at least 21 days before the meeting. The chairs of the Board and all committees, together with all other Directors, 
whenever possible attend the AGM and are available to answer questions raised by shareholders. Time is set aside 
specifically to allow such questions from attending members to any board member. For each vote, the number of 
proxy votes received for, against and withheld is announced at the meeting. The results of the AGM are subsequently 
published  on  the  Company’s  corporate  website  under  the  Stock  Exchange  (RNS)  Announcements  tab  – 
https://www.plexusplc.com/rns/. However, in 2020 and 2021 as a direct result of the Covid-19 pandemic, the 
Company held “closed” annual general meetings where only a quorum of members was present in a compliant and 
secure arrangement. The Company returned to holding a regular AGM in 2022. 

Institutional shareholders 
The Directors where possible seek to build relationships with institutional shareholders, as well as long term private 
investors who continue to remain supportive of the Company and its strategy. Shareholder relations are managed 
primarily by the CEO and Finance Director, and supported by the Technical Director, as appropriate. The CEO and 
Finance Director make presentations as and when required to institutional shareholders and analysts following the 
release of the full-year and half-year results. 

The Board as a whole is kept informed as necessary of the views and concerns of major shareholders and is aware 
that a number of investors and sources of finance have actively begun to move away from investing in oil and gas 
related companies. However, the Board believes that as the Company’s technology can claim to be greener than 
conventional wellhead designs in terms of its leak-proof sealing capabilities, that a case can be made for investing 
in the technology not just on superior technology grounds, but also on green ones. In addition, there are signs that 
the capital markets are beginning to open up to the oil and gas sector. Any significant investment reports from 
analysts are also circulated to the Board. The Non-Executive Chairman and Non-Executive Directors are available 
to meet with major shareholders if required to discuss issues of importance to them. 

3: Take into account wider stakeholder and social responsibilities and their implications for 
long-term success 
In December 2021 Plexus entered into an expanded licencing agreement with SLB, and in August 2021re-entered 
the exploration wellhead market in conjunction with SLB by way of a licence. Despite Plexus’ strategy continuing 
to evolve around such different ways of exploiting its proprietary POS-GRIP IP, the key stakeholders (both internal 
and external) and the way we engage with them has not changed. Stakeholders continue to consist of shareholders, 
employees, suppliers, customers, licensees, and advisers. 

Engaging with all our stakeholders as constructively as possible is important to Plexus, and we understand that 
good relations and sound business practices and principles all contribute to helping make a business a success. 
Feedback from shareholders is responded to where possible through interaction via letters, emails, phone calls, 
meetings, and the AGM. 

Where necessary the Board is updated on stakeholder engagement feedback should any issues arise, to stay abreast 
of stakeholder insights into what matters most to them and our business, and to enable the Board to understand and 
consider such issues in relevant decision-making. Aside from our shareholders, suppliers and customers, our 
employees are one of our most important stakeholder groups, and the Board monitors relevant employee issues 
through regular operating company operations reports.

Corporate Governance continued

Employees 
Plexus is a non-discriminatory employer which aims to eliminate unfair discrimination, harassment, victimisation 
and bullying. The Group is committed to ensuring that all individuals are treated fairly, with respect and are valued 
irrespective of disability, race, gender, health, social class, sexual preference, marital status, nationality, religion, 
employments status, age or membership or non-membership of a trade union. 

Staff and staff development continues to be important to the Group. To achieve this, the Group operates in-house 
training and accredited competency programmes ensure that necessary skill levels are maintained. 

Additionally, competency across the business has continued to evolve and broaden; particularly within workshop 
and office-based staff areas. The workshop competency system has been developed under the OPITO standards 
with a view to being accredited by OPITO. The office-based competency system has been developed under the 
OPITO standard as it is a concise system that supports the requirements of ISO9001:2015, for which Plexus has 
received and retains APIQR certification. 

Importantly  Health  and  Safety  is  an  operational  area  for  employee  stakeholders  where  Plexus  remains  fully 
committed to delivering the highest practical safety standards in everything we do. The Group continues to maintain 
a positive safety culture which is aligned with our Company Safety Values and are pleased to report our HSE culture 
remains strong across the business, and this is reflected by our LTCF and TRCF percentages both being zero, with 
no major findings during our most recent LRQA certification surveillance audits set against the ISO 45001:2018 
standard. 

Suppliers 
The Plexus business model has been built around the conscious decision of not having its own manufacturing 
facilities,  and  thereby  avoids  incurring  fixed  overheads  associated  with  such  activities.  This  means  that 
manufacturing is sub-contracted to carefully selected and assessed manufacturers and machine shops who must 
operate to prescribed high standards and requirements for delivering Plexus’ products’ high-quality threshold levels. 
Such relationships are of course important to Plexus and tend to be of a long-term nature reflecting the professional 
manner in which business is conducted. 

Customers 
We continue to seek opportunities for continual improvement regarding our relationships with customers, and our 
Business Management System complies with the ISO 45001 standard, demonstrating our commitment to attain 
and sustain the highest standards possible and allow us to respond quickly to client demands. 

Quality also remains a key focus in the delivery of our products and services demonstrated by the initial accreditation 
of API Q1 certification in February 2020 along with ISO 45001 certification in January 2022. Both of which are 
audited circa every two years to ensure Plexus are working to these accreditations. 

Modern Slavery 
In light of the ongoing activities and resultant human misery that have brought about the Modern Slavery Act 2015, 
a review of the requirements was carried out and a focus group was formed (HR, Executive Assistant, Contracts & 
Supply Chain) to create a Business Code of Conduct, Supplier Code of Conduct, Modern Slavery Statement and 
Whistleblowing procedure suitable for the business needs. Plexus takes such matters seriously, and it is considered 
good practice that Plexus manages its supply chain in line with the Modern Slavery Act to support the legislative 
requirement placed on the majority of our clients. In addition, these business tools have proven to be relevant for 
tendering processes as companies’ awareness levels about this pernicious crime increase. 

4: Embed effective risk management, considering both opportunities and threats, throughout 
the organisation 
Audit, risk and internal control 
Financial controls 
The Company has an established framework of internal financial controls. These are reviewed by the Executive 
Management, the Audit Committee and the Board as part of an ongoing assessment of significant risks by category 
facing the Company. 

The Group continues not to have an internal audit programme due to the small size of the administrative function 
and the level of Director review and authorisation of transactions. 

Plexus Holdings plc Annual Report 2023

26

Corporate Governance continued

The Board is responsible for reviewing and approving overall Company strategy, approving revenue and capital 
budgets and plans, and for determining the financial structure of the Company including treasury, tax and relevant 
dividend policy. Monthly results and variances from plans and forecasts are reported to the Board as part of the 
Board meeting procedures. In addition, the Board has a formal schedule of matters reserved for its decision which 
includes the setting of Company goals, objectives, budgets and other plans. All directors have access to independent 
professional  advice  at  the  Company’s  expense,  if  required,  as  well  as  to  the  advice  and  services  of  the 
company secretary. 

The Audit Committee assists the Board in discharging its duties regarding the interim and full year results, financial 
statements, accounting policies, and operational and financial controls. Duties include: 

(A)

to consider and recommend to the Board the approval of the appointment of the external auditors of the 
Company, the audit fee and other external remuneration of the auditors, and any questions of resignation or 
dismissal; 

(B)

to ensure the independence and objectivity of the external auditors. 

(C)

(D)

to discuss with the external auditors before each annual audit commences the nature and scope of the audit, 
and other relevant matters; 

to review the half year and annual financial statements before submission to the Board, focusing particularly 
on: 

(1)

any changes in accounting policies and practices; 

(2) major judgmental areas; 

(3)

(4)

(5)

(6)

significant adjustments resulting from the audit; 

the going concern assumption; 

compliance with accounting standards; and 

compliance with legal requirements. 

(E)

to discuss problems and reservations arising from final audits, interim reviews or otherwise (if any), and any 
matters the external auditors may wish to discuss (in the absence of the executive directors where necessary); 

(F)

to review management’s letter of representation; 

(G)

to review the nature and extent of non-audit services provided by the external auditors (if any) and be satisfied 
that the auditors’ independence and objectivity is maintained; 

(H)

to keep under review the effectiveness of the Company’s internal controls and risk management systems; 

(I)

(J)

to undertake an annual assessment of internal controls and risk management; 

to review the Company’s statement on internal control systems prior to endorsement by the Board; 

(K)

to consider the major findings of any internal investigations and management’s response; 

(L)

to review any internal audit programme and ensure that it is adequately resourced (currently not applicable); 

(M)

to consider other topics, as defined by and referred to the Audit Committee by the Board; and 

(N)

to review the Company’s arrangements for its employees to raise concerns, in confidence, about possible 
wrongdoing in financial reporting or other matters. The Committee shall ensure that these arrangements allow 
proportionate and independent investigation of such matters and appropriate follow up action. 

Risk assessment & management controls 
The Board recognises that maintaining sound controls and discipline is key to managing the downside risks to our 
plan. The Board has ultimate responsibility for the Group’s internal controls and for reviewing their effectiveness. 
However, any such system of internal control can provide only reasonable, but not absolute, assurance against 
material misstatement or loss. The Board considers that the internal controls in place, as summarised and explained 
below are appropriate for the size, complexity and risk profile of the Group. The principal elements of the Group’s 
internal control system include: 

l Management of the day-to-day activities of the Group by the Executive Directors; 

27

Plexus Holdings plc Annual Report 2023

Corporate Governance continued

l An organisational structure with defined levels of responsibility, which promotes responsible decision-making 

and implementation while minimising risks; 

l A comprehensive annual budgeting process producing an income statement, balance sheet and cash flow, which 

are approved by the Board; 

l Detailed monthly reporting of performance against budget; 
l Control over key areas such as capital expenditure authorisation and banking facilities; and 
l The Group continues to review its system of internal control to ensure compliance with best practice, while also 
having regard to its size and the resources available. As part of such controls the Company maintains a “Risk 
assessment & management document” which reviews as necessary both financial and non-financial controls 
areas and risks including Business (including IT); Compliance; Finance; Cash; Debtors; Fixed Assets; Other 
Debtors/Pre-payments; Creditors; Legal and Personnel. Such risks are assessed and reviewed, and changes made 
where appropriate. The key elements of the non-financial controls are set out below. 

Standards and policies 
The Board is committed to maintaining appropriate standards for the Company’s business activities and ensuring 
that these standards are set out in written policies. Key examples of such standards and policies include the ‘Anti 
Modern Slavery Policy’ and ‘Employee Code of Conduct’. Operating procedures for control of operations are 
clearly documented and set out in operation manuals where a key emphasis is on the Company actively assessing 
and minimising health and safety risks in all areas of the business and educating the workforce to provide as safe 
a working environment as possible. Managers are responsible for the implementation of these procedures and 
compliance is monitored. 

Approval process 
Material contracts are required to be reviewed by a senior Director of the Company and where necessary reviewed 
by external legal Counsel. 

Code of Conduct 
Our internal Code of Conduct includes guidance to employees on business integrity, anti-bribery, gifts, intellectual 
property and design rights. 

Legal controls 
Contracting with customers that include large international oil companies inevitably requires the entering into at 
times complex contracts where the need to address such issues as limitation of liability need careful review and 
negotiation.  The  Company’s  commercial  personnel  have  full  access  to  external  legal  advice  to  ensure  that 
appropriate steps are taken to help mitigate the damage that can result from poorly negotiated contracts. 

5: Maintain the board as a well-functioning, balanced team led by the chair. 
The Board currently comprises the Non-Executive Chairman, J. Jeffrey Thrall; three Executive Directors comprising 
Ben van Bilderbeek (CEO), Graham Stevens (FD); and Craig Hendrie (Technical Director); and two Non-Executive 
Directors, Kunming Liu and Charles Jones; and a Company Secretary (non-director) is in attendance at board meetings. 

The Audit Committee comprises two Non-Executive Directors, J. Jeffrey Thrall and Charles Jones and is scheduled 
to meet twice a year. It is the Audit Committee’s role to provide formal and transparent arrangements for considering 
how  to  apply  financial  reporting  and  internal  controls,  whilst  maintaining  an  appropriate  relationship  with  the 
independent auditors of the Group. In order to comply with best practice that at least one member has relevant financial 
experience, the Chairman of the Board sits on the Audit Committee. The Audit Committee review the Group’s policy 
on auditor rotation. The current auditors have served for 17 years and there are no current plans to retender. 

The Remuneration Committee comprises two Non-Executive Directors, J. Jeffrey Thrall and Charles Jones and 
meets when required. It is the Remuneration Committee’s role to set remuneration packages for individual Directors. 
Where necessary the Remuneration Committee obtains advice and research material from external remuneration 
specialists. There was no requirement for the Remuneration Committee to meet during the year as currently it is 
not felt appropriate to consider annual reviews or bonus arrangements. 

The Board considers that the Non-Executive Directors bring an independent judgement to bear, although it is 
recognised that factors such as length of service and shareholdings can have an impact. The Board is satisfied that 
it has a suitable balance between independence on the one hand, and knowledge of the Company on the other, to 

Plexus Holdings plc Annual Report 2023

28

Corporate Governance continued

enable it to discharge its duties and responsibilities effectively. In view of the specialist nature of the Company’s 
technology and IP, knowledge gained over time is considered an important part of the non-Executives understanding 
and therefore contribution to the business. 

All Directors are encouraged to apply their independent judgement and to challenge all matters, whether strategic 
or operational. 

During the last financial year eight Board meetings took place (including Board Committee meetings, but excluding 
meetings of the Audit Committee, and as disclosed above, the Remuneration Committee did not meet during the 
last financial year), and key Board activities as listed below are included but are not exclusive: 

l Discussed strategic priorities 
l Discussed the Group’s financial strength and strategy, including capital investments, shareholder returns and 

the dividend policy 

l Reviewed the performance of the Company’s licensees 
l Discussed actual and potential M&A activity 
l Discussed the internal risk management and assessment report 
l Reviewed feedback where relevant from shareholders post full and half year results 

Details of the dates of meetings during the last financial year of the Board, Board Committee, and Audit Committee, 
together with attendees are set out in the tables below. 

All members of the Board are expected to attend all scheduled main Board meetings whenever possible, but for 
practical purposes, the completion of the interim or full year accounts, or certain corporate transactions are delegated 
to a committee of the board to which all directors are entitled to attend by whatever practical means possible. The 
directors receive timely notice of each meeting along with an agenda and supporting papers which they review in 
advance of each meeting. 

Directors’ conflicts of interest 
The Company has effective procedures in place to monitor and deal with conflicts of interest. The Board is aware 
of the other commitments and interests and if necessary, the relevant Board member will recuse themselves from 
the matter at hand so as to avoid any conflicts for the individual or the Company. 

Executive Directors and Non-Executive Directors are expected to be available in person or virtually, and to have 
spent sufficient time studying all papers relevant to the regular meetings. Additionally, they are required to similarly 
attend meetings whenever required where non-routine course of business activity is going on, such as the Board 
approval of the expanded Licence Agreement with Cameron in November 2021, and the Jack-up Exploration 
Wellhead Licence Agreements in August 2021 and the recent decision to place a quantity of Treasury Shares. 

The executive members of the Board have considered the independence of their non-executive colleagues and have 
concluded they remain independent in the context that they provide independent oversight of the Company removed 
from day-to-day operations and constructively challenge the executive members of the Board.

In addition to the meetings specified above, the directors passed Directors’ Resolutions in Writing pursuant to 
Article 103 of the Company’s Articles of Association on the following dates in lieu of meetings being held: 

15 February 2023 
22 August 2023 
28 September 2023 

As already disclosed above, the Remuneration Committee did not meet during the last financial year. 

6: Ensure that between them the Directors have the necessary up-to-date experience, skills and capabilities 
The  Board  is  satisfied  that,  between  the  Directors,  it  has  an  effective  and  appropriate  balance  of  skills  and 
experience, including in the areas of finance, governance, commercial experience, public markets, oil and gas 
industry, and international trade. All Directors receive regular and timely information on the Group’s operational 
and financial performance. Relevant information is circulated to the Directors in advance of Board and Committee 
meetings. The business reports regularly on its headline performance against its agreed budget, and the Board 
reviews updates on performance and any significant variances are reviewed at each Board meeting. Directors’ 
Service contracts are available for inspection at the Company’s registered office and at the AGM. Further details 
of the Directors’ experience and skills are set out on page 19 of this report. 

The Directors are experienced in their own fields, and they act on their own initiative in ensuring they remain up 
to date in their respective skills where relevant by being members of relevant professional organisations, attending 
seminars  and  conferences,  attending  continuing  professional  development  courses  to  maintain  any  current 
accreditation and approaching the Company to arrange training where and if it is considered appropriate. The Board 
does not at the current time undertake specific due diligence on or carry out a formal review of an individual 
Director’s skills and training but is comfortable with such experience being appropriate from regular engagement 
and dialogue with each Director. No such review is anticipated at the current time. 

All Directors retire by rotation at regular intervals in accordance with the Company’s Articles of Association. 

Appointment, removal and re-election of Directors 
The Board makes decisions regarding the appointment and removal of Directors. As and when necessary suitable 
candidates are identified and put forward for consideration and additionally external views are sought, and, if 
relevant, background checks are undertaken in addition to any regulatory checks that are required. The process is 
formal and transparent, and consideration is given to what skills the candidate brings to the Board and how they 
will work and fit in with other Board members. The Company’s Articles of Association require that one-third of 
the Directors must stand for re-election by shareholders annually in rotation and that any new Directors appointed 
during the year must stand for re-election at the AGM immediately following their appointment. Graham Stevens 
and Charles Jones will retire by rotation this year, and being eligible, will offer themselves for re-election. 

Independent advice 
All Directors can take independent professional advice in the furtherance of their duties, if necessary, at the 
Company’s expense. In addition, the Directors have direct access to the advice and services of the Company 
Secretary, whose role is to consider compliance with primarily the Companies Act 2006 along with all other relevant 
legislation, the Finance Director, and the Company’s nominated adviser. 

The Company has not had to engage external advisers to the Board other than its usual professional advisers during 
the normal course of business. 

Plexus Holdings plc Annual Report 2023

Corporate Governance continued

The Company out-sources the company secretarial duties and responsibilities to a firm of professional company 
secretaries, (“the Out-Sourced Provider”), which engagement is overseen by the Finance Director. In addition to 
the routine company secretarial compliance work, the Out-Sourced Provider fulfils a wide-ranging support role to 
the FD on matters pertaining to the Companies Act, regulatory matters, transactional support, and ad hoc assistance 
generally. Its services are also available to any other board director who may wish to make an approach for 
independent advice which the Out-Sourced Provider strives to deliver in an impartial manner. 

7: Evaluate board performance based on clear and relevant objectives, seeking continuous 
improvement 
On an informal basis the Chairman Jeff Thrall and CEO Ben van Bilderbeek monitor the individual contributions 
of each of the members of the team to ensure that: 

l Their contribution is relevant and effective; 
l That they are committed; 
l Where relevant, they have maintained their independence; and 
l The skills of the board members are appropriate for the size and complexity of the Group. 

The responsibilities of the Chairman and CEO are summarised below: - 

The Chairman’s primary responsibility is to lead the Board effectively and to oversee the adoption, delivery and 
communication of the Company’s corporate governance model. The Chairman has sufficient separation from the 
day-to-day business to be able to make independent decisions. The Chairman is also responsible for making sure 
that the board agenda concentrates on the key issues, both operational and financial, including reviews of the 
Company’s strategy and its overall implementation. 

The CEO is responsible for the delivery of the business model within the timetable agreed by the Board. Keeps the 
Chairman and Board up to date with operational performance, risks and other issues to ensure that the business 
remains aligned with the agreed strategy. 

Because of the relative size of the Company, the composition of the Board and the level of experience of each 
Board member, the Company has not adopted a formal board evaluation process although keeps the topic under 
review and would conduct an assessment of the effectiveness of the whole Board’s performance if it were considered 
beneficial. 

The Board is mindful of the subject of succession planning, although has yet to adopt a formal process. At the 
present time, any succession planning deemed necessary would be carried out on an ad hoc basis. The Board keeps 
this subject under review. The Board is aware of the current shareholding structure and the significance of the 
founder’s  shareholding  and  is  always  mindful  of  the  need  to  balance  the  interests  of  all  shareholders  and 
stakeholders alike. 

8: Promote a corporate culture that is based on ethical values and behaviours 
The culture of the Group is to treat all of our customers, suppliers, shareholders and staff fairly and with respect 
and to be responsive and professional in all that we do whilst at all times being aware of the critical nature of the 
industry we operate in and the importance of monitoring and managing a range of risks that include political, legal, 
environmental, IP infringement, competitive risk, operational, liquidity and financial requirements, and credit. 

The risk assessment of such areas is an ongoing process, and the Board has established a process for identifying, 
evaluating and managing the more significant risk areas faced by the Group. One of the Board’s control documents 
is a detailed “Risks assessment & management document” which categorises risks in terms of – Business (including 
IT), Compliance, Finance, Cash, Debtors, Fixed assets, other Debtors/prepayments, Creditors, Legal, and Personnel. 
These risks are assessed and updated on a regular basis and can be associated with a variety of internal and external 
sources  including  regulatory  requirements,  disruption  to  information  systems  including  cyber-crime,  control 
breakdowns and social, ethical, environmental and health and safety issues. 

The Company ensures that ethical values and behaviours are recognised and respected by the adoption of appropriate 
policies which all members of staff are required to read and have ready access e.g., Code of conduct; anti-bribery 
and corruption policy, HR policy etc.

Prior to the start of each financial year, a schedule of Key Dates for that year’s Board and associated meetings is 
compiled to align as far as reasonably practicable with the Company’s financial calendar, while also ensuring an 
appropriate spread of meetings across the financial year. 

The Key Dates schedule is updated throughout the year as necessary. This may be supplemented by additional 
meetings as and when required, for example in relation to corporate activity. Alternatively, as had happened on 
three occasions during the year for practical reasons, the directors passed Directors’ Resolutions in Writing pursuant 
to the Company’s Articles of Association without formal meetings being held. The Board and its Committees receive 
appropriate and timely information prior to each meeting; a formal agenda is produced for each meeting, and Board 
and  Committee  papers  are  distributed  several  days  before  meetings  take  place. Any  Director  may  challenge 
Company proposals and decisions are taken democratically after discussion. Any Director who feels that any 
concern remains unresolved after discussion may ask for that concern to be noted in the minutes of the meeting, 
which are then circulated to all Directors. Any specific actions arising from such meetings are agreed by the Board 
or if relevant by a committee, and then followed up by the Company’s management. 

Roles of the Board, Chairman and Chief Executive Officer 
The Board is responsible for the long-term success of the Company. There is a formal schedule of reserved Board 
matters, and it is responsible for overall Group strategy; approval of major investments (whether Capex or Opex); 
approval of the annual and interim results; annual budgets; dividend policy; and Board structure. It also monitors 
the exposure to key business risks. There is a clear division of responsibility at the head of the Company. The 
Chairman is responsible for running the business of the Board and for reviewing appropriate strategic focus and 
direction. The Chief Executive Officer is responsible for proposing the strategic focus to the Board, implementing 
it once it has been approved and overseeing the management of the Company through the Executive Team. 

All  Directors  receive  regular  information  on  the  Group’s  operational  and  financial  performance.  Relevant 
information is circulated to the Directors in advance of meetings. The business regularly reports on its headline 
performance against its agreed budget, and the Board reviews updates on performance and any significant variances 
are reviewed at each Board meeting. Senior executives below Board level attend Board meetings where appropriate 
to present business updates. 

Executive Team 
The Executive Team consists of Ben van Bilderbeek (CEO), Graham Stevens (CFO) and Craig Hendrie (Technical 
Director), with input from the subsidiary company Directors and teams, all of which are full-time staff members 
and are responsible for the day-to-day management of the Group’s businesses and its overall trading, operational 
and financial performance in fulfilment of that strategy, as well as plans and budgets approved by the Board of 
Directors. They in conjunction with the Board manage and oversee key risks, and where appropriate management 
development. Graham Stevens is responsible for overseeing shareholder communications, and Craig Hendrie leads 
on R&D and engineering development activities. The Chief Executive Officer reports to the plc Board on issues, 
progress  and  recommendations  for  change.  The  controls  applied  by  the  Executive  Team  to  financial  and 
non-financial matters are set out earlier in this document 

Board Committees 
The Board is supported by the Audit Committee and where necessary the Remuneration Committee. Each committee 
has access to such resources, information and advice as it deems necessary, at the cost of the Company, to enable 
each committee to discharge its duties. The duties of the Audit Committee have been outlined in the detail on 
Principle 4 in this report.

and referred to the Remuneration Committee by the Board 

The governance framework is subject to review on an ongoing basis. No changes to the governance framework are 
currently planned. 

10: Communicate how the company is governed and is performing by maintaining a dialogue with 
shareholders and other relevant stakeholders 
The Company communicates with shareholders through Regulatory News Service announcements, the Annual 
Report and Accounts, full-year and half-year announcements, the Annual General Meeting (AGM), and when 
required one-to-one meetings with existing or potential institutional new shareholders. 

Most day-to-day shareholder interaction and communication is the responsibility of the CEO and the CFO. 

A  range  of  corporate  information  (including  all  Company  announcements)  is  also  available  to  shareholders, 
investors, and the public on the Company’s corporate website, www.plexusplc.com 

The Board receives when relevant, updates on the views of shareholders through briefings and reports from the 
Company’s brokers, Cavendish Capital Markets Limited. 

The Company communicates with institutional investors through briefings with management. In addition, analysts’ 
notes and brokers’ briefings are reviewed to achieve a wide understanding of investors’ views. 

Regular and open communication is encouraged between all layers of management to ensure that any issues or 
concerns can be raised.

The Company announces the results of all votes on resolutions proposed at any general meeting of the members of 
the Company by releasing a RNS to the London Stock Exchange immediately upon the conclusion of the meeting. 
It has not had occasion to announce where a significant proportion of votes (e.g., 20% or more of independent 
votes) has been cast against any particular resolution, although intends to include this information in the future, 
should such an occasion arise, including a summary of the actions it would take to understand the reasons behind 
such a voting result. The Company maintains on its website an increasing library of documents including all circulars 
to  shareholders,  RNS  news  releases  and  historic  documents  which  the  Board  considers  adequate  –

Audit Committee Report

Introduction 
This report details how the Audit Committee (“the Committee”) has met its responsibilities under its terms of 
reference. The Committee is a sub-committee of the Board and has the responsibility for reviewing and, where 
appropriate, recommending the approval of the Annual Reports and Accounts and interim financial statements by 
the  Board  with  whom  ultimate  responsibility  for  their  approval  rests.  The  Committee  does  not  believe  it  is 
appropriate  to  have  an  internal  audit  function  at  this  point  in  time  as  the  Group  is  relatively  small  and  not 
sufficiently complex. 

Members 
The members of the Audit Committee are Jerome Jeffrey Thrall (Chairman) and Charles Jones. The Executive 
Directors and the external auditors attend the meetings by invitation. The Board considers that the Committee has 
an appropriate and experienced blend of commercial, financial and industry expertise to enable it to fulfil its duties, 
and that the Committee Chairman has appropriate recent and relevant financial experience. 

Committee Meetings 
The Committee met twice during the year to 30 June 2023. One meeting related to the 2021-22 Annual Report and 
Accounts, and the second meeting was to review and sign off the 2022 Interim Financial Statements. The external 
auditors attended both meetings. 

Role and Responsibilities 
The Board has established an Audit Committee and set clear Terms of Reference so as to monitor the integrity of 
the Group’s financial statements and the effectiveness of the Group’s internal financial controls. 

The Terms of Reference are reviewed annually and amended where appropriate. During the year the Committee 
worked with management, the external auditors, and other members of the senior management team in fulfilling 
these responsibilities. The Committee considers financial reporting and internal controls. It also reviews the scope 
and results of the external audit and the independence and objectivity of the auditors. It meets at least twice a year 
and reviews the interim and annual financial statements before they are submitted for approval by the Board upon 
its recommendation. The Committee considers annually whether the auditors remain independent for the purposes 
of the audit and whether a separate internal audit function is required. As referenced above, the Committee does 
not believe it is appropriate to have an internal audit function at this time. 

The Committee report deals with the key duties and areas in which it plays an active role and has responsibility. 
These duties and areas include the following: 

Financial reporting and related primary areas of judgement; 
The external audit process; 

i)
ii)
iii) Risk management and internal controls; 
iv) Whistleblowing procedures 
v)

Consider and approve the appointment of the external auditors of the Company, the audit fee and other fees 
for non-audit related services; 

vi) Ensure the independence and objectivity of the external auditors; and 
vii) Review the external auditor’s management representations letter and management’s response. 

Annual Report and Accounts 
General 
The Committee has satisfied itself that the 2022-23 Annual Report and Accounts have been prepared in accordance 
UK-adopted international accounting standards, are fair, balanced and provide the information necessary for 
shareholders to assess the Group’s performance, business model and strategy. The Committee reviewed the key 
risk areas as identified in the Audit Plan document including revenue recognition and management override of 
controls. The Committee understands that the auditors have followed their procedures for reviewing these risks 
and have undertaken detailed testing as appropriate. 

In preparing the financial statements for the period, the main area requiring the exercise of management judgement, 
or a high degree of estimation was the valuation, and possible impairment, of intangibles. This was discussed with 
the auditor. The Committee, having reviewed management’s assessment of impairment, concluded that the relevant 
value in use was above the carrying value of the assets and hence no impairment provision was required. Further 

Plexus Holdings plc Annual Report 2023

information on the methodology and assumptions used in the valuation of intangible assets and the assessment of 
impairment thereof is given in notes 1.g and 1.h to the consolidated accounts on page 53, and in the Parent, company 
accounts on page 80. 

Going Concern 
The Committee reviewed the going concern paper prepared by management including detailed monthly financial 
forecasts, which included the twelve months from the date of signing the financial statements for 2022-23 and 
included related assumptions, risks and opportunities, sensitivities, areas for mitigation and contingency plans. 
Based on this review, the Committee has a reasonable expectation that the Group has adequate resources to continue 
in operational existence for the foreseeable future, being the period of twelve months from the date of signing the 
financial statements for 2022-23. Accordingly, the Committee concluded that it is appropriate to adopt the going 
concern basis in preparing the annual financial statements. The Committee agreed the group is reliant on raising 
additional funding, an event that was indicated at the time the convertible loan arrangements were entered into in 
October 2022, and there can be no certainty regarding the timing and quantum of future funding and therefore 
concur with management’s assessment that this indicates a material uncertainty which may cast significant doubt 
regarding the Group’s ability to continue as a going concern and this is adequately disclosed in note 1b. 

Internal Control Systems 
The Committee ensures that it monitors internal control systems reporting by the auditors and that there are no issues. 

Risk Management 
The Board has established an on-going process for identifying, evaluating and managing the more significant risk 
areas faced by the Group. One of the Board’s control documents is a detailed “Risks assessment & management 
document” which categorises risks in terms of – Business (including IT), Compliance, Finance, Cash, Debtors, 
Fixed Assets, Other debtors/prepayments, Creditors, Legal, and Personnel. These risks are assessed and updated 
when  necessary  and  can  be  associated  with  a  variety  of  internal  and  external  sources  including  regulatory 
requirements, disruption to information systems including cyber-crime, control breakdowns and social, ethical, 
environmental and health and safety issues. Further details on the Principal Risks and Risk Management may be 
found in the Strategic Report on page 9 of the financial statements. 

Board Conduct and Effectiveness Review 
As reported in the Corporate Governance section of the financial statements because of the relative size of the 
Company, the composition of the Board and the level of experience of each Board member, the Company has not 
adopted a formal whole board evaluation process although keeps the topic under review and would conduct one if 
it were considered necessary. 

The Board is mindful of the subject of succession planning, although has yet to adopt a formal process and, the 
Company  having  been  in  transition  since  the  disposal  of  the  rental  wellhead  Jack-up  business  in  2018,  any 
succession planning deemed necessary would be carried out on an ad hoc basis. The Board keeps this subject under 
review. The Board is aware of the current shareholding structure and the importance of the founder’s shareholding 
and is always mindful of the need to balance the interests of all shareholders and stakeholders alike. 

Auditor Independence 
The Committee satisfied itself on the auditors’ independence. The Group’s auditors Crowe UK LLP rotate the audit 
engagement partner every five years to ensure independence. 

Whistleblowing 
The Committee had no whistleblowing incidents reported directly or indirectly during the year to 30 June 2023. 

The Report of the Audit Committee was approved by a Committee of the Board of Directors on and signed on its 
behalf by: 

Jerome J Thrall 
Chairman of the Audit Committee

Remuneration Committee Report 

Introduction 
Companies trading on AIM are not required to provide a formal remuneration report. However, in line with current 
best practice this report provides information to enable a greater level of understanding as to how Directors’ 
remuneration is determined. 

The Remuneration Committee of the Board is responsible for considering Directors’ remuneration packages. The 
Committee comprises two Non-Executive Directors J. Jeffrey Thrall and Charles Jones. There was no requirement 
for the Remuneration Committee to meet during the last financial year. 

Remuneration policy 
The Group’s policy is to attract, retain and motivate high calibre executives capable of achieving the Group’s 
objectives. Executive Directors receive salaries, annual bonuses (as and when appropriate), medical cover, and 
pension scheme contributions. 

The Committee determines the policy of the overall remuneration package for Executive Directors and other senior 
executives. Basic salaries and benefits of all employees are normally reviewed every year, and the Group and the 
Committee as part of this process may seek advice from external remuneration consultants as and when appropriate. 
In reviewing salaries, consideration is given to personal performance, the Group’s overall performance and external 
comparative information. 

An annual performance or transaction related bonuses may be payable to Executive Directors and senior staff, and 
when appropriate an exercise is undertaken, again in conjunction where appropriate with external remuneration 
consultants to look at market comparisons, benchmarks, relative performance as well as consideration of strategic 
progress in addition to simply financial ones. Comparator group analysis includes oil and gas exploration companies 
with broadly similar market capitalisations and numbers of employees, as well as oil and gas service companies 
where, although the market capitalisation range is wide, it is still relevant as these are the sort of companies with 
which Plexus may compete for talent. 

Service contracts 
The Executive Directors have service agreements with the Company dated 25 November 2005 subject to termination 
upon twelve months’ notice being given by either party. 

Pensions 
The  Group  offers  a  contributory  group  stakeholder  pension  scheme,  into  which  the  Group  makes  matching 
contributions up to a pre-agreed level of base salary; the scheme is open to Executive Directors and permanent 
employees. Directors may alternatively choose to have contributions paid into existing personal pension plans, or 
to receive salary in lieu. 

Non-executive Directors 
The Non-Executive Chairman, J. Jeffrey Thrall, entered into a Letter of Appointment with the Company dated 
25 November 2005 for an initial term through to the first AGM and having been re-elected as a director either party 
can terminate upon three months’ notice being given. The subsequently appointed Non-Executive Directors, Charles 
Jones and Kunming Liu, entered into their Letters of Appointment with the Company dated 18 September 2014, 
and 17 December 2015 respectively, and having been re-elected as a director at the first respective AGM following 
their appointment, are subject to the same termination conditions as those applicable to Mr Thrall.

No non-executive share options have been granted, forfeited or exercised during the years to 30 June 2023 and 
2022. 

No options are expected to lapse at the AGM. 

On 9 July 2015 the Board of Plexus approved certain amendments to the rules of the Plexus Holdings plc 2005 
Share Option Scheme (the “Plan”) such that the Company is permitted to extend the exercise period for options 
granted under the Plan by a further ten years. On 9 July 2015 the directors approved an amendment to the rules of 
the scheme such that the Company is permitted to extend the exercise period for options granted under the scheme 
by a further ten years. Subsequently on 8 June 2017, 13 December 2019 and 25 March 2021 the Company entered 
into deeds of amendment with Ben van Bilderbeek, Graham Stevens, Craig Hendrie, and eleven employees in 
respect of options granted to them on 20 June 2007 and 17 December 2009 and 25 March 2011 under the scheme, 
to extend the exercise period by ten years, subject to all other terms of the scheme rules. 

The lowest mid-market price of the Company’s shares in the year to 30 June 2023 was 1.63p on the 12th and 13th 
of January 2023. The high price in the period to 30 June 2023 was 4.52p on 6th March 2023. The mid-market price 
on 30 June 2023 was 2.80p. 

The 6-year history of the share price on reporting date (30 June) is as follows, 2023: 2.80p, 2022: 2.80p, 2021: 
13.25p, 2020:14.00p, 2019: 40.50p and 2018: 46.90p. 

Total staff remuneration costs for the year, as set out in note 5 was £2.93m (2022: £2.86m). This compares to 
distributions to shareholders of nil (2022: £nil).

Statement of Directors’ Responsibilities

The directors are responsible for preparing the Directors’ Report, Strategic Report and the financial statements in 
accordance with applicable law and regulations. 

Company law requires the directors to prepare financial statements for each financial year. Under that law the 
directors have elected to prepare the group and parent company financial statements in accordance with UK-adopted 
international accounting standards. Under company law the directors must not approve the financial statements 
unless they are satisfied that they give a true and fair view of the state of affairs of the Company and of the Group 
and of the profit or loss of the Group for that period. In preparing these financial statements, the directors are 
required to: 

l

l

l

l

select suitable accounting policies and then apply them consistently; 
make judgements and accounting estimates that are reasonable and prudent; 
state whether applicable accounting standards have been followed, subject to any material departures disclosed 
and explained in the financial statements; 
prepare the financial statements on the going concern basis unless it is inappropriate to presume that the 
Group and the parent company will continue in business. 

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the 
Company’s transactions and disclose with reasonable accuracy at any time the financial position of the Company 
and enable them to ensure that the financial statements comply with the Companies Act 2006. They have a general 
responsibility for taking such steps as are reasonably open to them to safeguard the assets of the Group and to 
prevent and detect fraud and other irregularities. 

The directors are further responsible for ensuring that the Strategic Report and the Report of the Directors and other 
information included in the Annual Report and Financial Statements is prepared in accordance with applicable law 
in the United Kingdom. 

The directors are responsible for the maintenance and integrity of the corporate and financial information included 
on  the  Group’s  website  (www.plexusplc.com).  The  work  carried  out  by  the  auditors  does  not  involve  the 
consideration of these matters and, accordingly, the auditors accept no responsibility for any changes that may have 
occurred in the accounts since they were initially presented on the website. Legislation in the UK governing the 
preparation and dissemination of financial statements may differ from legislation in other jurisdictions.

Plexus Holdings plc Annual Report 2023

Independent Auditor’s Report to the Shareholders of Plexus Holdings plc

Opinion 
We have audited the financial statements of Plexus Holdings plc (the “Parent Company”) and its subsidiaries (the 
“Group”) for the year ended 30 June 2023, which comprise: 

l the Group statement of comprehensive income for the year ended 30 June 2023; 
l the Group and Parent Company statements of financial position as at 30 June 2023; 
l the Group and Parent Company statements of changes in equity for the year then ended; 
l the Group and Parent Company statements of cash flows for the year then ended; and 
l the notes to the financial statements, including significant accounting policies. 

The financial reporting framework that has been applied in the preparation of the financial statements is applicable 
law and UK-adopted international accounting standards. 

In our opinion the financial statements: 

l give a true and fair view of the state of the Group’s and of the Parent Company's affairs as at 30 June 2023 and 

of the Group’s loss for the period then ended; 

l have been properly prepared in accordance with UK-adopted international accounting standards;  
l 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. 

Material uncertainty related to going concern 
We draw attention to note 1(b) in the financial statements, which indicates that the Group and Parent Company 
will require further funding to continue its operations and meet its obligations. As stated in note 1(b), these events 
or conditions, along with the other matters as set forth in note 1(b), indicate that a material uncertainty exists that 
may cast significant doubt on the Group’s and Parent Company’s ability to continue as a going concern. Our opinion 
is not modified in respect of this matter. 

In auditing the financial statements, we have concluded that the directors’ use of the going concern basis of 
accounting in the preparation of the financial statements is appropriate. Our evaluation of the directors’ assessment 
of the Group’s and Parent Company’s ability to continue to adopt the going concern basis of accounting included  

l We obtained management’s going concern assessment, which covered a period up to 30 November 2024 and 

tested the mathematical accuracy of the model;  

l We challenged management over the level of certainty over revenues that were included;  
l Following this challenge, management prepared a stress-tested scenario that included only currently contracted 
revenues. This comprised income from the significant contract originally announced to the market in March 
2023, and the two contracts announced to the market in October and November 2023. 

l The stress test scenario included a requirement to raise funds in order to maintain sufficient cash levels for the 
going concern period. If this action was not successful, the Group and Parent Company would not have sufficient 
cash balances to meet their obligations during the going concern period. 

l We reviewed the disclosures made in the financial statements relating to going concern and agreed these to be 

consistent with the assessment and our conclusions 

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

Overview of our audit approach 

Materiality 
In planning and performing our audit we applied the concept of materiality. An item is considered material if it 
could reasonably be expected to change the economic decisions of a user of the financial statements. We used the 
concept of materiality to both focus our testing and to evaluate the impact of misstatements identified. 

Based on our professional judgement, we determined overall materiality for the Group financial statements as a 
whole to be £200,000 (2022: £275,000), based on 5% percent of Group loss before tax. Materiality for the Parent 
Company financial statements as a whole was set at £80,000 (2022: £65,000) based on a percentage of loss 
before tax. 

We use a different level of materiality (‘performance materiality’) to determine the extent of our testing for the 
audit of the financial statements.  Performance materiality is set based on the audit materiality as adjusted for the 
judgements made as to the entity risk and our evaluation of the specific risk of each audit area having regard to the 
internal control environment. This is set at £140,000 (2022: £192,500) for the group and £56,000 (2022: £45,500) 
for the parent. 

Where considered appropriate performance materiality may be reduced to a lower level, such as, for related party 
transactions and directors’ remuneration. 

We agreed with the Audit Committee to report to it all identified errors in excess of £10,000 (2022: £13,750). Errors 
below  that  threshold  would  also  be  reported  to  it  if,  in  our  opinion  as  auditor,  disclosure  was  required  on 
qualitative grounds. 

Overview of the scope of our audit 
Our Group audit was scoped by obtaining an understanding of the Group and its environment, including the Group’s 
system of internal control and assessing the risks of material misstatement in the financial statements. We also 
addressed the risk of management override of internal controls, assessing whether there was evidence of bias by 
the directors that may have represented a risk of material misstatement. 

The Group and its subsidiaries are accounted for from one central operating location, the Group’s registered office. 
There are two significant components in the Group: the Parent Company and Plexus Ocean Systems Limited. These 
two entities were subject to full scope audits by ourselves.  

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

We set out below, together with the material uncertainty related to going concern above, those matters we considered 
to be key audit matters. 

This is not a complete list of all risks identified by our audit.

Key audit matter

How the scope of our audit addressed the key audit 
matter 

1. Impairment of intangible assets, including goodwill  
(notes 10 and 11 
The Group carries intangible assets and goodwill at a 
net book value of £9.5 million (2022: £9.9 million). 
This balance is primarily represented by intellectual 
property, patent and other development expenditure. 

Management prepare annual impairment calculations 
to assess the carrying value of intangible assets as set 
out in the accounting policy in notes 1g and 1h to the 
financial statements. 

The performance of the impairment review requires 
management  to  make  a  number  of  judgements  and 
assumptions. 

As a result, we identified the impairment of intangible 
assets, including goodwill, as a key audit matter. 

2. Carrying value of Parent Company investments  
in subsidiaries and intercompany receivables  
(parent company note 5) 
The carrying value of investments in subsidiaries in the 
Parent Company financial statements at 30 June 2023 
was £8.3m (2022: £8.3m). Intercompany receivables 
were fully written off to a value of £nil during the year 
(2021: intercompany receivables of £7.5m). The value 
of these investments are almost entirely dependent on 
the successful trading of the subsidiary Plexus Ocean 
Systems Limited, utilising the IP included as intangible 
assets in the Group financial statements. 

l We evaluated, in comparison to the requirements set 
out in IAS 36, management’s assessment (based on 
value in use) as to whether goodwill or other intangible 
assets were impaired.  

l We  challenged,  the  key  estimates  included  in 
management’s  value  in  use  model,  including  the 
discount  rate  and  growth  rates.  This  included 
comparison to external benchmarks. 

l Sensitivity analysis was performed by management on 
the  key  assumptions  such  as  the  discount  rate  to 
identify those assumptions to which that the goodwill 
or intangible asset valuation was highly sensitive.  
l We have applied further sensitivities over the discount 
rate and growth rate and challenged management on 
the likelihood of such a scenario occurring, and on 
what remedial actions would be taken.  

l We  also  evaluated  whether  information  existed  in 
relation to the fair value less costs to sell, that would 
support the recoverable value of the assets. 

l We held discussions with management to determine 
whether indicators of impairment existed in relation to 
these balances and concurred with their conclusion that 
an impairment review was required due to the level of 
year  end  market  capitalisation  of  the  Group  in 
comparison to the investment carrying value.  

l In  assessing  whether  impairment  was  required,  our 
work was substantially the same as described above in 
the impairment consideration of the intangible assets, 
as the recoverability of the investment values is closely 
linked to these assets. 

3. Revenue recognition (notes 1d and 2) 
Revenue  is  recognised  in  accordance  with  the 
accounting policy set out in the financial statements. 

The  principal  income  stream  during  the  period  was 
revenue from rental of equipment. 

The principal area of risk was considered to be cut off, 
being that revenue is recognised in the correct period; 
and existence, being the judgement that performance 
obligations  have  been  met  and  so  revenue  should 
be recognised. 

l We assessed that the accounting policy conformed with 
the requirements of IFRS15 and tested its application to 
a  sample  of  contracts,  including  the  significant  new 
contract announced to the market in March 2023.  
l We performed cut off testing by tracing a sample of 
transactions  pre  and  post  year  end  to  evidence  of 
whether  performance  obligations  had  been  met,  to 
ensure revenue is being recorded in the correct period.  
l A  sample  of  revenue  transactions  were  verified  to 
supporting invoices, delivery confirmation, and traced 
through to receipt of cash.

Our audit procedures in relation to these matters were designed in the context of our audit opinion as a whole. They 
were not designed to enable us to express an opinion on these matters individually and we express no such opinion. 

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

Our responsibility is to read the other information and, in doing so, consider whether the other information is 
materially inconsistent with the financial statements or our knowledge obtained in the audit or otherwise appears 
to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are 
required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, 
based on the work we have performed, we conclude that there is a material misstatement of this other information, 
we are required to report that fact. We have nothing to report in this regard. 

Opinion on other matter prescribed by the Companies Act 2006 
In our opinion based on the work undertaken in the course of our audit  
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. 

Matters on which we are required to report by exception 
In light of the knowledge and understanding of the Group and the Parent Company and their environment obtained 
in the course of the audit, we have not identified material misstatements in the strategic report or the directors’ report. 
We have nothing to report in respect of the following matters where 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 the directors for the financial statements 
As explained more fully in the directors’ responsibilities statement set out on page 41, the directors are responsible 
for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for 
such internal control as the directors determine is necessary to enable the preparation of financial statements that 
are free from material misstatement, whether due to fraud or error. 

In preparing the financial statements, the directors are responsible for assessing the Group’s and Parent Company’s 
ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the 
going concern basis of accounting unless the directors either intend to liquidate the Group or the Parent Company 
or to cease operations, or have no realistic alternative but to do so. 

Auditor’s responsibilities for the audit of the financial statements 
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from 
material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. 
Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with 
ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error 
and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the 
economic decisions of users taken on the basis of these financial statements.

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in 
line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including 
fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below: 

l We obtained an understanding of the legal and regulatory frameworks that are applicable to the Group, and the 
procedures in place for ensuring compliance. The most significant regulations identified were compliance with 
the Companies Act 2006 and the AIM rules. Our work included direct enquiry of the directors, who oversee all 
legal proceedings, reviewing Board minutes and inspection of correspondence and accreditation renewals. 

l We communicated the relevant laws and regulations identified to all members of the engagement team, and 
remained alert to any indication of non compliance with laws and regulations, or potential fraud, throughout our 
audit work. 

l As part of our audit planning process we assessed the different areas of the financial statements, including 
disclosures, for the risk of material misstatement. This included considering the risk of fraud where direct enquiries 
were made of management and those charged with governance concerning both whether they had any knowledge 
of actual or suspected fraud and their assessment of the susceptibility of fraud. We considered the risk was greater 
in areas that involve significant management estimate or judgement. Based on this assessment we designed audit 
procedures  to  focus  on  the  key  areas  of  estimation  or  judgement,  this  included  specific  testing  of  journal 
transactions, both at the year end and throughout the year. 

l We used data analytic techniques to identify any unusual transactions or unexpected relationships, including 

considering the risk of undisclosed related party transactions.  

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

Use of our report 
This report is made solely to the company’s members, as a body, in accordance with Chapter 3 of Part 16 of the 
Companies Act 2006. Our audit work has been undertaken so that we might state to the company's members those 
matters we are required to state to them in an auditor's report and for no other purpose. To the fullest extent permitted 
by law, we do not accept or assume responsibility to anyone other than the company and the company's members 
as a body, for our audit work, for this report, or for the opinions we have formed.

Notes to the Consolidated Financial Statements

1.

Summary of significant accounting policies 
The following accounting policies have been applied consistently in dealing with items which are considered 
material in relation to the financial information. 

Basis of preparation 

a.
The consolidated financial statements have been prepared in accordance with UK-adopted international 
accounting standards and interpretations issued by the UK Endorsement Board and are in accordance with 
the Companies Act 2006. 

There are a number of standards, amendments to standards, and interpretations which have been issued by 
the UKEB that are effective in future accounting. The Directors’ have assessed the impact of these standards 
and do not expect any significant impact to the Group on their adoption. 

The Group financial statements are presented in sterling and all values are rounded to the nearest thousand 
pounds except where otherwise indicated. 

The financial information has been prepared under the historical cost convention except where fair value 
adjustments are required. 

Going concern 

b.
At the year end, the Group had cash and cash equivalents of £1.45m, with no bank borrowings. Since the 
year end the group has raised £0.7m through a loan facility and a further £0.5m from the sale of treasury 
shares. Both transactions are detailed in note 30. The Group’s financial risks and the management of capital 
risks are set out in Note 25 to the Financial Statements. 

After careful enquiry and review of available financial information, including multi-scenario projections and 
cash flows for the period to 30 November 2024 (which included a severe, but plausible downside scenario), 
the  Directors  consider  it  appropriate  to  continue  to  adopt  the  going  concern  basis  of  accounting  in  the 
preparation of the consolidated and company financial statements. However, in each scenario noted above, 
the group is reliant on a future funding event and failure to secure funding would have a material impact on 
the group. There can be no certainty regarding the timing and quantum of such future funding and therefore 
this indicates a material uncertainty which may cast significant doubt regarding the Group’s ability to continue 
as a going concern. The financial statements do not include the adjustments that would result if the Group 
and the company were unable to continue as a going concern 

Notwithstanding the above management are confident regarding the ability of the group to secure a future 
funding  event  due  its  recent  successful  sale  of  treasury  shares  (see  note  30)  and  the  current  market 
capitalisation of the group. 

Basis of consolidation 

c.
The Group’s financial statements consolidate the financial statements of Plexus Holdings plc and the entities 
it controls (its subsidiaries) and are drawn up to 30 June each year. Control comprises the power to govern 
the financial and operating policies of the investee so as to obtain benefit from its activities and is achieved 
through direct and indirect ownership of voting rights, currently exercisable or convertible potential voting 
rights. Subsidiaries are consolidated from the date of their acquisition, being the date on which the Group 
obtains control, and continue to be consolidated until the date that such control ceases. The financial statements 
of subsidiaries are prepared for the same reporting year as the parent company, using consistent accounting 
policies. All intercompany balances and transactions, including unrealised profits arising from intra group 
transactions, have been eliminated in full. Unrealised losses are eliminated unless the transaction provides 
evidence of an impairment of the asset transferred. 

Within twelve months of the date of acquisition of a subsidiary undertaking a re-assessment is made of the fair 
value of the assets and liabilities acquired in order to assess any provisional values used in initial accounting. 

51

Plexus Holdings plc Annual Report 2023

Notes to the Consolidated Financial Statements continued

1.

Summary of significant accounting policies (continued) 
The financial statements of the Company and its subsidiaries are prepared in sterling (the functional currency), 
which is the currency that best reflects the economic substance of the underlying events and circumstances 
relevant to the Group. Transactions and balances in foreign currencies are converted into sterling in accordance 
with the principles set forth by IAS 21 (“The Effects of Changes in Foreign Exchange Rates”). Accordingly, 
transactions and balances have been converted as follows: 

l Monetary assets and liabilities – at the rate of exchange applicable at the reporting date; and 

l

Income and expense items – at exchange rates applicable as of the date of recognition of those items. 
Exchange gains and losses are recognised in the consolidated statement of comprehensive income. 

Revenue 
d.
Sale of equipment 
The Group sells a range of equipment derived from its proprietary technology, spares and ancillary equipment. 
Revenue from the sale of equipment is recognised when performance obligations are met. This is considered 
to be on acceptance of the equipment by the customer. Invoicing and subsequent payment follow the transfer 
of ownership. 

Rental income 
The Group rents out equipment to customers. Revenue from rental contacts, all of which are short term, is 
recognised in the statement of comprehensive income on a straight-line basis as the performance obligations 
are satisfied over time. Rental income is invoiced on a monthly basis. Milestone payments received on rental 
contracts are recognised as contract liabilities, with recognition of revenue being deferred until performance 
obligations are met. 

Service and engineering income 
The Group provides Field Service Technicians to its customers, on daily rate basis. Revenue from service 
contracts is recognised on a performance basis as work is undertaken. Customers are invoiced following 
receipt of a signed field service ticket. Engineering work can operate on a similar basis or on a pre-agreed 
price for a specified scope of work and be invoiced on completion. 

Royalty income 
The Group has licensing agreements which are subject to royalty payments. Royalty income is recognised 
under the terms and conditions of the underlying licensing agreement, and revenue is recognised when 
performance obligations as specified in each royalty agreement are satisfied.. 

Rebillable income 
The Group passes on third party costs to customers at cost plus mark-up where applicable. The level of mark-
up is specified in the underlying contract with the customer. Revenue is invoiced and recognised, along with 
the associated expenditure in the period in which it relates. 

Cost of sales 

e.
Cost of sales includes salary and related costs for service personnel, depreciation, refurbishment costs on 
rental assets and other costs which are directly attributable to revenue generating projects. 

Income taxes and deferred taxation 

f.
The income tax credit for the period comprises current and deferred tax. Tax is recognised in the income 
statement, except to the extent that it relates to items recognised in other comprehensive income or directly 
in  equity.  In  this  case,  the  tax  is  also  recognised  in  other  comprehensive  income  or  directly  in  equity, 
respectively. 

The current income tax credit is calculated on the basis of the tax laws enacted or substantively enacted at the 
reporting date in the countries where the Company and its subsidiaries operate and generate taxable income. 
Management periodically evaluates positions taken in tax returns with respect to situations in which applicable 
tax regulation is subject to interpretation. It establishes provisions where appropriate on the basis of amounts 
expected  to  be  paid  to  the  tax  authorities.  Deferred  income  tax  is  recognised  on  temporary  differences 
arising  between  the  tax  bases  of  assets  and  liabilities  and  their  carrying  amounts  in  the  consolidated 
financial statements. 

Plexus Holdings plc Annual Report 2023

52

Notes to the Consolidated Financial Statements continued

1.

Summary of significant accounting policies (continued) 
Deferred income tax is determined using tax rates (and laws) that have been enacted or substantively enacted 
by the reporting date and are expected to apply when the related deferred income tax asset is realised, or the 
deferred income tax liability is settled. 

Deferred income tax assets are recognised only to the extent that it is probable that future taxable profit will 
be available against which the temporary differences can be utilised. 

As set out in note 22 the Group operates a share option scheme. Where the market price of the shares at the 
year-end exceeds the option price there is a potential tax deduction. This is treated as a deferred tax asset. 
The portion of the expected future tax deduction which is less than or equal to the associated cumulative 
IFRS2 charge is recognised in the income statement. The balance of the credit is recognised directly in equity. 

Goodwill 

g.
Purchased goodwill (representing the excess of the fair value of the consideration given over the fair value 
of the separable assets acquired) arising on business combinations in respect of acquisitions is capitalised. 

Goodwill is not amortised; it is measured at cost less any accumulated impairment losses. Goodwill is 
reviewed for impairment at least annually. 

Goodwill is monitored by management at the operating segment level. All goodwill has been allocated to the 
single operating segment, which is considered to be a group of similar cash generating units (CGU’s) for 
impairment purposes. 

Intangible assets and amortisation 

h.
Patents are recorded initially at cost and amortised on a straight-line basis over 20 years which represents the 
life of the patent. The Group operates a policy of continual patent enhancement in order that technology 
enhancements and modifications are incorporated within the registered patent, thereby protecting the value 
of technology advances for a full 20-year period. 

Intellectual Property rights are initially recorded at cost and amortised over 20 years on a straight-line basis. 
The technology defined by the Intellectual Property is believed to be able to generate income streams for the 
Group for many years; key Intellectual Property is protected by patents; the lowest common denominator in 
terms of economic life of the intangible assets is the life of the original patents and therefore the life of the 
Intellectual Property has been matched to the remaining life of the patents protecting it. 

Development expenditure is capitalised in respect of development of patentable technology at cost including 
an allocation of own time when such expenditure is incurred on separately identifiable technology and its 
future recoverability can reasonably be regarded as assured. Any expenditure carried forward is amortised 
on a straight-line basis over its useful economic life, which the directors consider to be 20 years. 

Computer software is amortised over 2 to 5 years on a straight-line basis. 

In all cases the amortisation period represents the expected useful life of the asset. 

Amortisation is charged to the Administrative Expenses line of the Statement of Comprehensive Income. 

Expenditure on research and development, which does not meet the capitalisation criteria, is written off to 
the Statement of Comprehensive Income in the period in which it is incurred. 

The  carrying  value  of  intangible  assets  is  reviewed  on  an  on-going  basis  by  the  directors,  and  where 
appropriate, provision is made for any indication of impairment in value. Where impairment arises, the 
recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). 
Where it is not possible to estimate the recoverable amount of an individual asset, an estimate is made of the 
recoverable amount of the cash-generating unit to which the asset belongs. 

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

Notes to the Consolidated Financial Statements continued

1.

Summary of significant accounting policies (continued) 
amount of an asset is estimated to be less than its carrying amount, the carrying amount of the asset is reduced 
to its recoverable amount. 

Any impairment loss would be recognised immediately in the Statement of Comprehensive Income. 

Property, plant and equipment 

i.
Property, plant and equipment are stated at cost less accumulated depreciation. Cost represents the cost of 
acquisition or construction, including the direct cost of financing the acquisition or construction until the 
asset  comes  into  use.  Depreciation  is  provided  to  write  off  the  cost  or  valuation  of  property,  plant  and 
equipment less the estimated residual value by equal instalments over their estimated useful economic lives 
as follows: 

         Buildings                                Over  the  remaining  life  of  the  lease  on  the  land  on  which  the  building  is 

         Tenant improvements             Over the remaining life of the lease of the relevant building 
         Equipment                              7% – 50% per annum 
         Motor vehicles                        20% per annum 

constructed 

The expected useful lives and residual values of property, plant and equipment are reviewed on an annual 
basis and, if necessary, changes in useful life or residual value are accounted for prospectively. 

The carrying value of property, plant and equipment is reviewed for impairment whenever events or changes 
in circumstances indicate the carrying value may not be recoverable. 

An item of property, plant and equipment is derecognised upon disposal or when no future economic benefits 
are expected to arise from the continued use of the asset. Any gain or loss arising on derecognition of the 
asset (calculated as the difference between the net disposal proceeds and the carrying amount of the item) is 
included in the Statement of Comprehensive Income in the period the item is derecognised. 

l

IFRS 5 sets out the criteria for designating an asset as held for sale 
l Management must be committed to a plan to sell the asset; 
An active program to find a buyer must have been initiated; 
The asset must be actively marketed for sale at a price reasonable to its current fair value; 
The sale is expected to be completed within 1 year from the date of classification; 
Significant changes to the plan are unlikely. 

l

l

l

Should the above criteria be met the asset, or group of assets, is reclassified to current assets, at the lower of 
its carrying amount and its fair value less costs to sell. 

Cash and cash equivalents 

j.
Cash and cash equivalents comprise cash balances and call deposits. Bank overdrafts that are repayable on 
demand form an integral part of the Group’s cash management and are included as a component of cash and 
cash equivalents for the purpose of the statement of cash flows. 

Foreign currencies 

k.
Transactions in foreign currencies are recorded using the rate of exchange ruling at the date of the transaction. 
Monetary assets and liabilities denominated in foreign currencies are translated using the rate of exchange 
ruling at the statement of financial position date and the gains or losses on translation are included in the 
Statement of Comprehensive Income. The functional currency of the Group is pounds sterling. 

Leases 

l.
Short-term and low value rentals are charged to the Statement of Comprehensive Income on a straight-line 
basis over the period of the lease. 

A lessee will be required to recognise assets and liabilities for all leases with a term of more than 12 months 
(unless the underlying asset is of low value) and is required to present depreciation of leased assets separately 
from interest on lease liabilities in the consolidated statement of comprehensive income. 

The right of use asset is initially measured at cost and is subsequently measured at cost less accumulated 
depreciation and impairment and adjusted for any amendment to the lease liability. The lease liability is initially

Summary of significant accounting policies (continued) 
measured at the present value of the lease payments due at inception, and is subsequently adjusted for lease 
payments and interest, or any amendment to the lease liability. 

The Group has taken the exemptions where applicable for low value and short-term leases. A lessor will 
continue to classify its leases as operating leases or financing leases, and to account for those two types of 
leases separately. 

Inventory 

m.
Inventory is stated at the lower of cost and net realisable value. Cost is determined on a first in first out basis 
and includes all direct costs incurred and attributable production overheads. Net realisable value is based on 
estimated selling price allowing for all further costs to completion and disposal. 

Pensions 

n.
The Group offers a contributory Group stakeholder pension scheme, into which the Group will make matching 
contributions up to a pre-agreed level of base salary; the scheme is open to executive directors and permanent 
employees. Directors may choose to have contributions paid into personal pension plans. Payments to the 
defined contribution retirement benefit plans are recognised as an expense when the employees have rendered 
service entitling them to contributions. 

Classification of financial instruments issued by the Group 

o.
In accordance with IAS 32, financial instruments issued by the Group are treated as equity (i.e., forming part 
of shareholders’ funds) only to the extent that they meet the following two conditions: 

(a)

they include no contractual obligations upon the Company (or Group as the case may be) to deliver 
cash or other financial assets or to exchange financial assets or financial liabilities with another party 
under conditions that are potentially unfavourable to the Company (or Group); and 

(b) where the instrument will or may be settled in the Company’s own equity instruments, it is either a non-
derivative  that  includes  no  obligation  to  deliver  a  variable  number  of  the  Company’s  own  equity 
instruments or is a derivative that will be settled by the Company exchanging a fixed amount of cash or 
other financial assets for a fixed number of its own equity instruments. 

To the extent that this definition is not met, the proceeds of issue are classified as a financial liability. Where 
the instrument so classified takes the legal form of the Company’s own shares, the amounts presented in these 
financial statements for called up share capital and share premium account exclude amounts in relation to 
those shares. 

Finance payments associated with financial liabilities are dealt with as part of finance charges. Finance 
payments associated with financial instruments that are classified as part of shareholders’ funds (see dividends 
policy), are dealt with as appropriations in the reconciliation of movements in shareholders’ funds. 

Share based payments 

p.
The Group issues share options to directors and employees, which are measured at fair value at the date of 
grant. The fair value of the equity settled options determined at the grant date is expensed on a straight-line 
basis over the vesting period based on an estimate of the number of options that will actually vest. The Group 
has adopted a Stochastic model to calculate the fair value of options, which enables the Total Shareholder 
Return (TSR) performance condition attached to the awards to be factored into the fair value calculation. 

q. Management of capital 
The Group’s capital is comprised of share capital, shares held in treasury and retained earnings. (Notes 20 
and 21). 

The Group’s objective when managing capital is to safeguard its ability to continue as a going concern so 
that it can continue to provide returns to shareholders. 

The Group sets the amount of capital in proportion to its assessment of the risks that it faces. The Group 
manages the capital structure and adjusts it in the light of changes in economic conditions and the risk 
characteristics of the underlying assets. In order to maintain or adjust the capital structure the Group may 
adjust the value of dividends paid or issue new equity.

Associates 

r.
Associates are initially recognized at cost, including any directly attributable acquisition cost. Associates are 
accounted for using the equity method. Under this method, the investment is initially recognized at cost, and 
adjustments are made to the carrying amount to reflect the investor’s share of the associate’s profit or loss 
and other comprehensive income. Dividends received from associates reduce the carrying amount of the 
investment. If there is an indication of impairment, the carrying amount of the investment is assessed, and 
any impairment loss is recognized in the income statement. 

Convertible loans 

s.
Convertible loans are initially recognised at their fair value, which includes any directly attributable transaction 
costs. The loan notes can be settled in cash, with an additional 20% redemption interest on the principal 
amount or converted into new shares where the principal amount will be settled at a 20% discount to the share 
price paid by investors in a qualifying financing event. The 20% is representative of a 25% redemption period 
that will be accrued over the life of the convertibles. 

Should the qualifying event occur causing conversion to shares prior to the maturity date, the carrying amount 
of the Convertible Loan Note will be derecognised and shares arising on conversion of the notes shall be 
issued and allotted by the company on the conversion date. The remaining redemption premium will be 
recognised as a debit to the income statement upon conversion. 

Significant judgements made by management 

t.
Estimates and judgements are continually evaluated and are based on historical experience and other factors, 
including expectations of future events that are believed to be reasonable under the circumstances. 

The principal areas in which significant judgements have been made by management are as follows: 

(a)

In assessing the intangibles assets for impairment, the directors have applied judgment when preparing 
projections of future revenues expected to be derived from exploiting the Group’s intangible assets in 
future periods as part of their consideration of impairment. The core technology has proven commercial 
value, despite the recent trading losses made. The projections for future application are subject to a 
significant degree of judgement. 

(b) The directors have applied judgement when considering the recognition of a deferred tax asset in relation 
to future utilisation of trading losses. That recognition is predicated on a judgement in relation to the 
probable extent that sufficient taxable profit will be available against which the unused tax losses can 
be utilised. In arriving at that judgement, the directors have adopted modelling based on approved 
budgets for the next 12 months, and modelling for an additional two years, and applied estimates and 
assumptions consistent with those set out in note 11 in relation to expectation of future developments, 
sales models and growth rates. 

(c)

Judgement was used to conclude whether the investment in associate met the criteria of IFRS 5 as being 
held for sale, at the balance sheet date. On the basis the asset is available for sale in its present condition 
and management were committed to a plan to sell the asset to an identified buyer at an appropriate 
valuation by December 2023 the asset sale was considered highly probably and the criteria set out in 
IFRS 5 had been met. 

Key assumptions and sources of estimation 

u.
The life of the Group’s Intellectual Property is estimated with reference to the lifespan of the patents which 
help protect the knowledge and the Group’s ability to generate income from it. Changes to these estimates 
can result in significant variations in the carrying value and amounts charged to the consolidated statement 
of comprehensive income in specific periods. 

When measuring goodwill and intangible assets for impairment a range of assumptions are required and these 
are detailed in the Goodwill and Intangible Asset notes 1g and 1h and note 11 to the financial statements. 
When reviewing the Intellectual Property (“IP”) for impairment a multi scenario model is employed which 
includes an organic sales model and a licensing model for the two main stands of IP, Conventional and 
Deepwater. A number of assumptions and judgements are used in the modelling, including assumed growth 
rates, cost inflation and salary inflation. A sensitivity analysis is applied to the modelling including flexing 

Plexus Holdings plc Annual Report 2023

Notes to the Consolidated Financial Statements continued

1.

Summary of significant accounting policies (continued) 

the weight average cost of capital and revenue growth rate. In all scenarios the discounted cash flows are in 
excess of the carrying values of the IP. 

Provisions requiring management estimates and judgements: A provision has been made against slow moving 
inventory based upon historical experience of the viability of the older parts as technological improvements 
are made. Changes to these estimates can result in significant variations in the carrying value and amounts 
charged to the consolidated statement of comprehensive income in specific periods. 

In forming their assessment of going concern, the Directors prepare budgets and forecasts, which include 
multi-scenario modelling. The main area of estimation within the modelling is revenue levels. The Directors 
estimate revenues based on their current expectation from contracted works and other projects considered 
very likely to proceed. These are sensitised for more severe scenarios, to ensure that the Group has enough 
cash headroom to ensure the going-concern assumption is appropriate. Refer to going concern disclosure at 
note 1b.

Segment Reporting 
The Group derives revenue from the sale of its POS-GRIP technology and associated products, the rental of 
equipment utilising the POS-GRIP technology and service income principally derived in assisting with the 
commissioning and on-going service requirements of our equipment. These income streams are all derived 
from the utilisation of the technology which the Group believes is its only segment. 

Per IFRS 8, the operating segment is based on internal reports about components of the group, which are 
regularly reviewed and used by the board of directors being the Chief Operating Decision Maker (“CODM”). 

All of the Group’s non-current assets are held in the UK.

As outlined in the accounting policy (note 1f) deferred tax assets are recognised only to the extent that it is 
probable that future taxable profit will be available. The deferred tax asset relates to losses to the value of the 
deferred tax losses and is reviewed at the end of each reporting period. The Group has previously recognised 
a deferred tax asset based upon its mid-term forecast profitability. On the basis losses have not been utilised in 
the current financial year management consider that the probable threshold is not met and have released the 
asset  to  the  extent  there  are  not  sufficient  taxable  temporary  differences.  Once  this  threshold  can  be 
demonstrated an asset will be recognised. At 30 June 2023 the Group has tax losses available of £24.5m (2022: 
£21.5m).

from the directors’ knowledge and experience. 

Management have determined the CGUs by identifying separate strands of intellectual property which can be

Intangible Assets (continued) 
When assessing the carrying value of the Group’s assets the key assumptions on which the valuation is based 
are that: 

l

l

l

Industry acceptance will result in continued growth of the business above long-term industry growth rates 
Management considers this to be appropriate for a new technology gaining industry acceptance, 

Prices will rise with inflation, 

Costs,  in  particular  direct  costs  and  staff  costs  are  based  on  past  experiences,  and  management’s 
knowledge of the industry, 

These assumptions were determined from the directors’ knowledge and experience. 

The value in use calculation is based on cash flow forecasts derived from the most recent financial model 
information available. Although the Group’s technology is proven and has proven commercial value the 
exploitation  of  opportunities  beyond  the  rental  wellhead  exploration  equipment  services  market  are  at  a 
relatively early stage and the commercialisation process is expected to be a long term one. Based on the level 
secured income for the next financial year, management expect this will lead to a wider uptake and acceptance 
of the of the technology. The cash flow forecasts therefore extend to 2043 to ensure the full benefit of all current 
projects is realised. The rationale for using a timescale up to 2043 with growth projections which increase in 
the first five years and decline thereafter, is that as time progresses, Plexus expects to gain an increasing foothold 
in the surface, subsea and other equipment markets, including the recent re-entry into the Jack-up exploration 
rental wellhead sector. As the Group is starting from a base point of trading the growth rates are expected to be 
high in the initial years (varying from 50% to 400% depending on the model employed) then in later years 
where the technology becomes established the expected rate of growth declines (varying from 5% to 10 
depending on the model employed). 

The key assumptions used in these calculations include discount rate (10.87%), revenue projections, growth 
rates, expected gross margins and the lifespan of the Group’s technology. 

Management estimates the discount rates using pre-tax rates that reflect current market assessments of the time 
value of money and risks specific to the Group and the markets in which it operates. Revenue projections, 
growth rates, margins and technology lifespans are all estimated based on the latest business models and the 
most recent discussions with customers, suppliers and other business partners. 

Management regularly assesses the sensitivity of the key assumptions, including a sensitivity analysis, and the 
probability that any of them would change to the degree that the carrying value would exceed the recoverable 
amount. It would require significant adjustments to key assumptions before the goodwill and other intangibles 
would be impaired. 

Patent  and  other  development  costs  are  internally  generated  Note  1h  provides  additional  information  on 
intangible assets.

During the year the Directors were committed to a plan to sell the Group’s investment in associate (note 13), 
this along with the other recognition criteria included within “IFRS 5, Non-current assets held for sale and 
discontinued operations” including the asset being available for immediate sale in its present condition and 
the sale is considered to be highly probable meant the asset has been presented as an asset held for sale.  

The  asset  held  for  sale  in  the  prior  year  relates  to  a  property  that  was  sold  on  28  February  2023  for  a 
consideration of £1.05m. The Group had agreed a sale in principle in the prior year. The building was 
previously marketed for sale. In line with IFRS5 the asset was held for sale at the lower of its carrying value 
and fair value. A further fair value adjustment of £50k to reduce the carrying value of the asset to its fair value 
has been recognised in the current financial year.

22. Share based payments 

Share options have been granted to subscribe for ordinary shares, which are exercisable between 2023 and 
2031 at prices ranging from £0.385 to £1.18. At 30 June 2023 there were 3,577,899 options outstanding. 

The Company has an unapproved share option scheme for the directors and employees of the Group. Options 
are exercisable at the quoted mid-market price of the Company’s shares on the date of grant. The options may 
vest in three equal portions, at the end of each of three assessment periods, provided that the option holder is 
still  employed  by  the  Group  at  vesting  date  and  that  the Total  Shareholder  Return  (TSR)  performance 
conditions are satisfied. Options that do not meet the TSR criteria at the first available vesting date may vest 
at the end of the complete assessment period, provided that the compounded TSR performance is met over 
the complete assessment period. Vested but unexercised options ordinarily expire on the tenth anniversary of 
the date of grant. The options are equity settled. 

On 9 July 2015, the directors approved an amendment to the rules of the scheme such that the Company is 
permitted  to  extend  the  exercise  period  for  options  granted  under  the  scheme  by  a  further  ten  years. 
Subsequently on 8 June 2017, 13 December 2019 and 25 March 2021 the Company entered into deeds of 
amendment with Ben van Bilderbeek, Graham Stevens, Craig Hendrie, and eleven employees in respect of 
options granted to them on 20 June 2007 and 17 December 2009 and 25 March 2011 under the scheme, to 
extend the exercise period by ten years, subject to all other terms of the scheme rules. 

Details of the share options outstanding during the year are as follows:

25. Financial Instruments and risk management 

Treasury management 
The Group’s activities give rise to a number of different financial risks: market risk (including foreign currency 
exchange risk and interest rate risk), credit risk and liquidity risk. The Group’s management regularly monitors 
the risks and potential exposures to which the Group is exposed and seeks to take action, where appropriate, 
to minimise any potential adverse impact on the Group’s performance. 

Risk management is carried out by Management in line with the Group’s Treasury policies. The Group’s 
Treasury policies cover specific areas, such as foreign exchange risk, interest rate risk and investment of excess 
cash. The Group’s policy does not permit entering into speculative trading of financial instruments and this 
policy has been applied throughout the year. 

(a) Market risks 

(i)

Foreign currency exchange risk 

The Group is exposed to foreign exchange risk arising from various currencies. In order to protect the 
Group’s statement of financial position from movements in exchange rates, the Group converts foreign 
currency balances into sterling on receipt so far as they will not be used for future payments in the 
foreign currency. 

The Group carefully monitors the economic and political situation in the countries in which it operates 
to ensure appropriate action is taken to minimise any foreign currency exposure. 

The Group’s main foreign exchange risk relates to movements in the sterling/US dollar and sterling/euro 
exchange rates. Movements in these rates impact the translation of US dollar and euro denominated net 
assets. Outstanding debts are in GBP and USD, minimal cash is held in foreign currency. Therefore, the 
Group has minimal foreign exchange risk for the reporting period.

Notes to the Consolidated Financial Statements continued

25. Financial Instruments and risk management (continued) 

(ii)

Interest rate risk 

The Group has historically financed its operations through a mixture of retained profits and bank 
borrowings. The Group borrows in sterling at floating rates of interest. 

The Group is also exposed to interest rate risk on cash held on deposit. The Group’s policy is to maximise 
the return on cash deposits whilst ensuring that cash is deposited with a financial institution with a credit 
rating of ‘AA’ or better. 

During the year-end, the Lombard facility was repaid in full, resulting in the Group having no bank 
borrowings which significantly minimises interest rate risk. 

(b) Credit risk 
The Group’s credit risk primarily relates to its trade receivables. Responsibility for managing credit risks lies 
with the Company’s management. 

The Group applies the IFRS 9 simplified approach to measure expected credit losses for all trade receivables 
and contract assets. To measure the expected credit losses, trade receivables and contract assets have been 
grouped based on shared credit risk characteristics and the number of days past due. The expected loss rates 
are based on payment profiles of sales and the corresponding historical credit losses experienced within this 
period. The amount of expected credit losses is updated at each reporting date to reflect changes in credit risk 
since initial recognition of the respective financial instrument. 

The investment portfolio consists of funds invested in high-yield bonds with reputable financial institutions. 
The Company do not consider the investment portfolio presents a credit risk. 

A  customer  evaluation  is  typically  obtained  from  an  appropriate  credit  rating  agency.  Where  required, 
appropriate trade finance instruments such as letters of credit, bonds, guarantees and credit insurance will be 
used to manage credit risk. 

The Group’s major customers are typically large companies which have strong credit ratings assigned by 
international  credit  rating  agencies.  Where  a  customer  does  not  have  sufficiently  strong  credit  ratings, 
alternative forms of security such as the trade finance instruments referred to above may be obtained. The 
Group’s customer base is concentrated on a few major companies. 

Management review trade receivables across the Group based on receivable days’ calculations to assess 
performance. There is significant management focus on receivables that are overdue. All receivables are with 
large corporations with good credit history with which the entity has not experienced any recoverability issues 
in the past. Individual trade receivables and contract assets are written off when management deem them not 
to be collectible. A bad debt provision of £277k has been in place since the prior year in relation to LLC 
Gusar, which cannot currently be settled while current economic sanctions remain in place. 

Amounts deposited with banks and other financial institutions also give rise to credit risk. This risk is managed 
by limiting the aggregate amount of exposure to any such institution by reference to their rating and by regular 
review of these ratings. The possibility of material loss in this way is considered unlikely. 

The currency composition of trade receivables at the year-end was:

(c) Liquidity risk 
The Group has historically financed its operations through equity financing and bank borrowings. The Group 
has continued with its policy of ensuring that there are sufficient funds available to meet the expected funding 
requirements of the Group’s operations and investment opportunities. The Group monitors its liquidity position 
through cash flow forecasting. Based on the current outlook the Group has sufficient funding in place to meet 
its future obligations.

The  Group  has  classified  its  financial  instruments  into  the  three  levels  prescribed  under  the  accounting 
standards. The definition of the levels is as follows. 

Level 1: The fair value of financial instruments traded in active markets (such as publicly traded derivatives, 
and trading and available-for-sale securities) is based on quoted market prices at the end of the reporting period. 
The quoted market price used for financial assets held by the Group is the current bid price. These instruments 
are included in level 1.

Notes to the Consolidated Financial Statements continued

25. Financial Instruments and risk management (continued) 

Level  2:  The  fair  value  of  financial  instruments  that  are  not  traded  in  an  active  market  (for  example, 
over-the-counter derivatives) is determined using valuation techniques which maximise the use of observable 
market data and rely as little as possible on entity-specific estimates. If all significant inputs required to fair 
value an instrument are observable, the instrument is included in level 2. 

Level 3: If one or more of the significant inputs is not based on observable market data, the instrument is 
included in level 3. This is the case for unlisted equity securities. 

Non-current assets (note 16) meet the level 1 criteria and have been recorded in the statement of financial 
position at fair value. As at 30 June 2023 the fair value of the financial assets held by the Group are £nil 
(2022: £101k).  

The interest rate and currency profiles of the Group’s financial liabilities at 30 June 2023 are as follows:

In October 2022 Plexus raised £1,550,000 through the issue of 1,550,000 convertible loan notes. The loan 
notes are non-interest bearing and have a maturity date being 24 months after issue.  

The loan notes can be settled in cash, with an additional 20% redemption interest on the principal amount or 
converted into new shares where the principal amount will be settled at a 20% discount to the share price paid 
by investors in a qualifying financing even. The 20% discount noted about equates to a 25% premium on the 
principal amount. Therefore, a redemption premium of £387,500 will be recognised over the two-year term. 
At the reporting date finance costs include £152k in relation to the accrued redemption premium.

Notes to the Parent Company Financial Statements

1.

Summary of significant accounting policies 
The following accounting policies have been applied consistently in dealing with items which are considered 
material in relation to the financial information. 

Basis of preparation 

a.
The  Company’s  financial  statements  have  been  prepared  in  accordance  with  UK-adopted  international 
accounting standards and interpretations issued by the UK Endorsement Board and are in accordance with 
the Companies Act 2006. 

There are a number of standards, amendments to standards, and interpretations which have been issued by 
the UKEB that are effective in future accounting. The Directors’ have assessed the impact of these standards 
and do not expect any significant impact to the Company on their adoption. 

The Company financial statements are presented in sterling and all values are rounded to the nearest thousand 
pounds except where otherwise indicated. 

The financial information has been prepared under the historical cost convention except where fair value 
adjustments are required. 

Income taxes and deferred taxation 

b.
The income tax expense for the period comprises current and deferred tax. Tax is recognised in the income 
statement, except to the extent that it relates to items recognised in other comprehensive income or directly 
in  equity.  In  this  case,  the  tax  is  also  recognised  in  other  comprehensive  income  or  directly  in  equity, 
respectively. 

The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at 
the reporting date in the countries where the Company and its subsidiaries operate and generate taxable 
income. Management periodically evaluates positions taken in tax returns with respect to situations in which 
applicable tax regulation is subject to interpretation. It establishes provisions where appropriate on the basis 
of amounts expected to be paid to the tax authorities. 

Deferred income tax is recognised on temporary differences arising between the tax bases of assets and 
liabilities and their carrying amounts in the consolidated financial statements. 

Deferred income tax is determined using tax rates (and laws) that have been enacted or substantively enacted 
by the reporting date and are expected to apply when the related deferred income tax asset is realised, or the 
deferred income tax liability is settled. 

Deferred income tax assets are recognised only to the extent that it is probable that future taxable profit will 
be available against which the temporary differences can be utilised. 

As set out in note 22 of the Group accounts, the Company operates a share option scheme. Where the market 
price of the shares at the year-end exceeds the option price there is a potential tax deduction. This is treated 
as a deferred tax asset. The portion of the expected future tax deduction which is less than or equal to the 
associated cumulative IFRS2 charge is recognised in the income statement. The balance of the credit is 
recognised directly in equity. 

Intangible assets and amortisation 

c.
Patents are recorded initially at cost and amortised on a straight-line basis over 20 years which represents the 
life of the patent. The Group operates a policy of continual patent enhancement in order that technology 
enhancements and modifications are incorporated within the registered patent, thereby protecting the value 
of technology advances for a full 20-year period. 

Intellectual Property rights are initially recorded at cost and amortised over 20 years on a straight-line basis. 
The technology defined by the Intellectual Property is believed to be able to generate income streams for the 
Group for many years; key Intellectual Property is protected by patents; the lowest common denominator in 
terms of economic life of the intangible assets is the life of the original patents and therefore the life of the 
Intellectual Property has been matched to the remaining life of the patents protecting it.

1.

Summary of significant accounting policies (continued) 
Development expenditure is capitalised in respect of development of patentable technology at cost including 
an allocation of own time when such expenditure is incurred on separately identifiable technology and its 
future recoverability can reasonably be regarded as assured. Any expenditure carried forward is amortised 
on a straight-line basis over its useful economic life, which the directors consider to be 20 years. 

Amortisation is charged to the Administrative Expenses line of the Statement of Comprehensive Income. 

Expenditure on research and development, which does not meet the capitalisation criteria, is written off to 
the Statement of Comprehensive Income in the period in which it is incurred. 

The  carrying  value  of  intangible  assets  is  reviewed  on  an  on-going  basis  by  the  directors  and,  where 
appropriate, provision is made for any impairment in value. It would require a substantial movement (over 
100%) in the assumptions employed in valuations before there would be any impairment to intangible assets. 

Potential impairment of intangible assets has been reviewed and is outlined in note 1h in the Group accounts, 
with no impairment required. 

Investments 

d.
The investment in subsidiary undertakings is stated at cost less provision for impairment. Cost is the amount 
of  cash  paid  or  the  fair  value  of  the  consideration  given  to  acquire  the  investment.  Income  from  such 
investments is recognised only to the extent that the Company receives distributions from accumulated profits 
of the investee company arising after the date of acquisition. 

Potential impairment of investments and the intangible assets each subsidiary undertaking holds has been 
reviewed and is outlined in note 1h in the Group accounts, with no impairment required. The impairment 
modelling is based on long-term modelling of the Group’s IP, to evidence that no impairment in investments 
is required. 

Cash and cash equivalents 

e.
Cash and cash equivalents comprise cash balances and call deposits. Bank overdrafts that are repayable on 
demand form an integral part of the Company’s cash management and are included as a component of cash 
and cash equivalents for the purpose of the statement of cash flows. 

Foreign currencies 

f.
Transactions in foreign currencies are recorded using the rate of exchange ruling at the date of the transaction. 
Monetary assets and liabilities denominated in foreign currencies are translated using the rate of exchange 
ruling at the statement of financial position date and the gains or losses on translation are included in the 
Statement of Comprehensive Income. 

Pensions 

g.
The Group offers a contributory Group stakeholder pension scheme, into which the Group will make matching 
contributions up to a pre-agreed level of base salary; the scheme is open to executive directors and permanent 
employees. Directors may choose to have contributions paid into personal pension plans. 

Dividends 

h.
Dividends are recognised when they become legally payable. In the case of interim dividends to equity 
shareholders,  this  is  when  they  are  paid.  In  the  case  of  final  dividends,  this  is  when  approved  by  the 
shareholders at the AGM. Dividends unpaid at the statement of financial position date are only recognised as 
a liability at that date to the extent that they are appropriately authorised and are no longer at the discretion 
of  the  Company.  Unpaid  dividends  that  do  not  meet  these  criteria  are  disclosed  in  the  notes  to  the 
financial statements.

Summary of significant accounting policies (continued) 

Classification of financial instruments issued by the Group 

i.
In accordance with IAS 32, financial instruments issued by the Group are treated as equity (i.e., forming part 
of shareholders’ funds) only to the extent that they meet the following two conditions: 

(a)

they include no contractual obligations upon the Company (or Group as the case may be) to deliver 
cash or other financial assets or to exchange financial assets or financial liabilities with another party 
under conditions that are potentially unfavourable to the Company (or Group); and 

(b) where the instrument will or may be settled in the Company’s own equity instruments, it is either a 
non-derivative that includes no obligation to deliver a variable number of the Company’s own equity 
instruments or is a derivative that will be settled by the Company exchanging a fixed amount of cash or 
other financial assets for a fixed number of its own equity instruments. 

To the extent that this definition is not met, the proceeds of issue are classified as a financial liability. Where 
the instrument so classified takes the legal form of the Company’s own shares, the amounts presented in these 
financial statements for called up share capital and share premium account exclude amounts in relation to 
those shares. 

Finance payments associated with financial liabilities are dealt with as part of finance charges. Finance 
payments associated with financial instruments that are classified as part of shareholders’ funds (see dividends 
policy), are dealt with as appropriations in the reconciliation of movements in shareholders’ funds. 

Share based payments 

j.
The Company issues share options to directors and employees, which are measured at fair value at the date 
of grant. The fair value of the equity settled options determined at the grant date is expensed on a straight-line 
basis over the vesting period based on an estimate of the number of options that will actually vest. The Group 
has adopted a Stochastic model to calculate the fair value of options, which enables the Total Shareholder 
Return (TSR) performance condition attached to the awards to be factored into the fair value calculation. 

Key assumptions and sources of estimation 

k.
The estimated life of the Company’s Intellectual Property is estimated with reference to the lifespan of the 
patents which protect the knowledge and their forecast income generation. 

When measuring Intellectual Property for impairment a range of assumptions are required and these are 
detailed in the Intangible Assets note above. 

The recoverability of loan between parent company and subsidiary is a key estimate. Recoverability is based 
on future financial performance. 

2.

Profit for the year 
As permitted by section 408 of the Companies Act 2006, the parent company’s Statement of Comprehensive 
Income has not been included in these financial statements. The parent company’s loss after tax for the year 
was £8,757k (2022: loss of £13,527k). The Company had revenue of £nil for the financial year (2022: £277k).

Prepayments relate to prepaid amounts for services to be consumed over the next 12 months. 

The recoverability of all receivables has been assessed. The receivables due from group companies was 
forgiven at the reporting date, due to a low chance of recoverability, resulting in a write-off of £7.48m.

The Company’s activities give rise to a number of different financial risks: market risk (including foreign 
currency exchange risk and interest rate risk), credit risk and liquidity risk. The Company’s management 
regularly monitors the risks and potential exposures to which the Company is exposed and seeks to take 
action, where appropriate, to minimise any potential adverse impact on the Company’s performance. 

Risk management is carried out by Management in line with the Company’s Treasury policies. The Company’s 
Treasury policies cover specific areas, such as foreign exchange risk, interest rate risk and investment of 
excess cash. The Company’s policy does not permit entering into speculative trading of financial instruments 
and this policy has been applied throughout the year. 

Foreign currency exchange risk 

(a) Market risks 
(i)
The Company is exposed to foreign exchange risk arising from various currencies. In order to protect the 
Company’s statement of financial position from movements in exchange rates, the Company converts foreign 
currency  balances  into  sterling  on  receipt  so  far  as  they  will  not  be  used  for  future  payments  in  the 
foreign currency. 

The Company carefully monitors the economic and political situation in the countries in which it operates to 
ensure appropriate action is taken to minimise any foreign currency exposure. 

Interest rate risk 

(ii)
The Company is also exposed to interest rate risk on cash held on deposit. The Company’s policy is to 
maximise the return on cash deposits whilst ensuring that cash is deposited with a financial institution with 
a credit rating of ‘AA’ or better.

11. Financial instruments and risk management (continued) 

(b) Credit risk 
The  Company’s  credit  risk  primarily  relates  to  its  inter-company  loans  and  inter-company  receivables. 
Management have reviewed the recoverability of intercompany loan balances at the reporting date, this has 
resulted  in  a  write-off  of  £nil  (2022:  £nil)  charged  in  the  year  from  the  assessment  of  credit  losses  on 
Group balances. 

Amounts deposited with banks and other financial institutions also give rise to credit risk. This risk is managed 
by limiting the aggregate amount of exposure to any such institution by reference to their rating and by regular 
review of these ratings. The possibility of material loss in this way is considered unlikely. 

(c) Liquidity risk 
The Company has historically financed its operations through equity finance and the flow of inter¬company 
loan repayments. The Company has continued with its policy of ensuring that there are sufficient funds 
available  to  meet  the  expected  funding  requirements  of  the  Company’s  operations  and  investment 
opportunities. The Company monitors its liquidity position through cash flow forecasting. Based on the current 
outlook the Company has sufficient funding in place to meet its future obligations.

Limited a company in turn controlled by the van Bilderbeek family and related trusts., (together, the “Loans”). 
The Loans accrue interest at a rate of 8 per cent. per annum and the balance, plus any interest accrued, is 
repayable after 12 months. Alongside the loan agreements, the Company has also entered into Primary and a 
Secondary call option agreements with Ben van Bilderbeek and PPI. These option agreements provide the 
Lenders with the right to exercise an option to have their portion of the Loans repaid in shares owned by Plexus 
Ocean Systems Limited in Kincardine Manufacturing Services Limited, a precision engineering company in 
which Plexus holds a 49% interest following a strategic investment in December 2018. 

In October 2023 Plexus sold 2,750,000 of the shares held in treasury at an average price of 19.97 pence per 
share, to raise gross proceeds of £549,230.

POS-GRIP friction-grip technology is based 

on a very simple concept. A compressive 

force is applied on the outside of a wellhead 

or pipe, to flex it inwards. As the bore of 

the vessel moves inwards, it makes contact 

with an inner pipe (or hanger) on the inside. 

Sufficient contact force is generated to fix 

the inner member (hanger) in place through 

friction between the two components.

In wellheads, POS-GRIP can replace the 

conventional load shoulder or slips to 

provide an improved hanger support 

mechanism.

Utilising our patented POS-GRIP technology, 

we are continually developing new wellhead 

equipment to meet our customers’ 

requirements, delivering solutions for 

the surface, subsea and decommissioning 

markets.

P OS-G RIP APPLICATIONS

Wellheads

Production wellheads and surface subsea 

have all benefitted from POS-GRIP. Casing and 

tubing hangers can be gripped, but POS-GRIP 

can also be used to support wearbushings, 

BOP test tools and seal sleeves.

Connectors

POS-GRIP is ideal for high integrity, low 

fatigue connector applications. Wellhead 

connectors, riser connectors, subsea jumper 

connectors, pipeline connectors, and even 

vessel mooring connectors can benefit from 

the simplicity of POS-GRIP.

Metal-to-metal sealing

Wellheads and connectors can both benefit 

from the direct contact created when the 

POS-GRIP metal to metal HG® seal is activated, 

delivering an unrivalled gas-proof seal.
