Plexus Holdings PLC ('Plexus' or 'the Company')

Sale of Wellhead Exploration for Jack-Up Applications Business to TechnipFMC and Circular re: General Meeting

Plexus Holdings PLC, the AIM quoted oil and gas engineering services business and owner of the proprietary POS-GRIP® friction-grip method of wellhead engineering, is pleased to announce the sale of its wellhead exploration equipment and services business for Jack-Up applications (the 'Jack-up Business') to FMC Technologies Limited ('TFMC'), a subsidiary of TechnipFMC (Paris:FTI)(NYSE:FTI) one of the leading oil & gas service and equipment companies (the 'Disposal'). In addition and as part of the Transaction, Plexus, Plexus' subsidiary POSL and TFMC will also be entering into a Collaboration Agreement ('CA') which establishes a framework to work together both on the development of existing POS-GRIP IP for applications outside of jack-up exploration, as well as future new technologies.

The Disposal follows the signing of a conditional Business Purchase Agreement ('BPA') by Plexus, POSL and TFMC. Under the terms of the BPA, the Plexus Group will receive an initial gross cash consideration of £15,000,000, subject to certain adjustments, with an additional sum of up to £27,500,000 payable dependent on the future performance of the Jack-up Business during a three-year earn-out period. The earn-out has the potential to increase the total cash consideration to £42,500,000.

The Disposal is in line with Plexus' strategy of increasing industry awareness of its POS-GRIP friction grip technology by initially focusing on proving the superior qualities of its equipment within the jack-up wellhead exploration market, where to date its technology has been deployed on hundreds of wells worldwide, before targeting other markets such as surface production, subsea and de-commissioning. The Board of Plexus believes that the Disposal represents a significant milestone for the Company as it demonstrates the attractiveness of POS-GRIP technology.

To facilitate a smooth transition of the Jack-up Business, the parties will enter into a Transitional Services Agreement through which the Plexus Group will provide certain services to TFMC on a transitional basis. At the same time, Plexus and TFMC have also agreed to enter into two Licence Agreements, one royalty free and the other royalty bearing, which deliver to TFMC the necessary IP which is held by the Company and which relates to the Jack-up Business.

Circular re: General Meeting

Pursuant to Rule 15 of the AIM Rules, the Disposal is deemed to constitute a disposal resulting in a fundamental change of business, and is therefore conditional on the consent of Shareholders being obtained at a General Meeting. The Company will shortly post a circular ('Circular') and Notice of General Meeting ('GM') to all shareholders. An extract of the Circular appears below.

Plexus' CEO Ben Van Bilderbeek, said: 'I am pleased to announce this important transaction with TechnipFMC, one of the world's foremost oil and gas service companies. I believe that the Disposal and Collaboration Agreement with TechnipFMC opens up new opportunities for our technology. TechnipFMC is acquiring a business which has supplied a wide range of blue chip operators of the calibre of BP, Centrica, ENI, Maersk, Royal Dutch Shell, Statoil, and Total with wellheads for use on hundreds of wells worldwide and which already has a strong market reputation in the UKCS and ECS, particularly for HP/HT applications. Going forwardthere are numerous opportunities for the application of POS-GRIP technology and encouragingly, as the recent contract win from Centrica for the supply of surface production application equipment demonstrates, we are already making progress in this regard.'We look forward to working closely with TechnipFMC to ensure the earn-out period is as successful as possible for both companies and also under the Collaboration Agreement with the potential to further develop our existingPOS-GRIP IP for applications outside of the Jack Up exploration business. I will be working hard as CEO of Plexus with my team to grow the business and repeat the past success we have enjoyedinraising standards for HP/HT exploration wellheads in the wider energy sector, as well as focusing on generating shareholder value.'

TechnipFMC's President of Surface Technologies business Richard Alabaster, said:'I am very pleased that we have reached this agreement, which fits within TechnipFMC Surface Technologies' strategy to extend and strengthen our position in exploration-drilling products and services while leveraging our global field presence. It also enhances TechnipFMC's capability in HP/HT applications.'

Proposed Disposal of Plexus' Jack-up Exploration Drilling Equipment and Services Business and Notice of General Meeting

1. INTRODUCTION

The Company has agreed the sale of its wellhead exploration equipment and services business for Jack-up applications (the 'Jack-up Business') to FMC Technologies Limited ('TFMC'), a subsidiary of TechnipFMC one of the leading oil & gas service and equipment companies in the world with a market capitalisation of approximately US$12.5 billion (Paris:FTI) (NYSE:FTI). This follows the signing of a Business Purchase Agreement by Plexus, Plexus subsidiary POSL and TFMC. Under the terms of the BPA, on Completion, the Plexus Group will receive an initial gross cash consideration of £15,000,000, subject to certain adjustments, with an additional sum of up to £27,500,000 payable dependent on the future performance of the Jack-up Business during a three-year earn-out period. The earn-out, which has the potential to increase the total cash consideration to £42,500,000, allows Plexus to benefit from any growth in activity in the jack-up exploration market during the period, as well as TFMC's extensive global presence.

The Disposal of the Jack-up Business is in line with Plexus' strategy to increase industry awareness of its POS-GRIP friction grip technology by initially focusing on proving the superior qualities of its equipment in the jack-up exploration market, where to date its technology has been deployed on hundreds of wells worldwide, before targeting other markets such as surface production wellheads, subsea wellheads and de-commissioning. The Board of Plexus believes that the Disposal represents a significant milestone for the Company as it demonstrates the attractiveness of POS-GRIP technology. Following Completion, Plexus will focus on establishing its technology and equipment in other markets, and in this regard the Board believes that the recent announcement of a contract with Centrica for the supply of surface production application equipment is particularly encouraging.

In line with this objective and as part of the Transaction, Plexus and TFMC will also be entering into a Collaboration Agreement which establishes a framework to work together both on the development of existing POS-GRIP IP for applications outside of jack-up exploration, as well as on future new technologies. The Collaboration Agreement provides for the formation of a joint steering committee comprising representatives of Plexus and TFMC, who will be able to explore potential areas of future collaboration. This proposed future collaboration will therefore provide a platform from which the Company can seek to further develop and commercialise its POS-GRIP technology across a range of other applications.

At the same time Plexus and TFMC have agreed to enter into two Licence Agreements, one royalty free and the other royalty bearing, which deliver to TFMC the necessary IP which is held by the Company and which relates to the divested Jack-up Business.

To facilitate a smooth transition of the Jack-up Business, the parties will be entering into a Transitional Services Agreement through which the Plexus Group will provide certain services to TFMC on a transitional basis. TFMC will also enter into a sub-lease on one of the two main Plexus buildings in Aberdeen.

As the Jack-up Business accounted for approximately 99.7 per cent. of the Company's total revenues in the year ended 30 June 2016, pursuant to Rule 15 of the AIM Rules, the Disposal is deemed to constitute a disposal resulting in a fundamental change of business, and is therefore conditional on the consent of Shareholders being obtained at the General Meeting.

The purpose of the Circular is to provide Shareholders with further information on the Transaction, the Resolution, details of the Company's ongoing business and strategy, and the reasons why the Directors consider that the Transaction is in the best interests of the Company and its Shareholders as a whole.

The Directors unanimously recommend that shareholders vote in favour of the Resolution to be proposed at the General Meeting.

2. BACKGROUND TO AND REASONS FOR THE TRANSACTION

Introduction

AIM-traded oil and gas engineering services company Plexus has developed a range of products and applications based on its patent-protected POS-GRIP friction-grip method of wellhead engineering. Included among these are the Company's POS-GRIP friction-grip exploration wellhead equipment and associated tooling. Up until now, the Company's core business has been the rental of this equipment to major oil and gas operators for use on jack-up exploration wells around the world, particularly for High Pressure/High Temperature ('HP/HT') applications. To date, Plexus wellheads have been used on hundreds of wells operated by a customer base, which includes blue-chip customers such as BP, Centrica, Maersk, Royal Dutch Shell, Statoil, and Total.

IP-led

Since it was established, Plexus has focused on being an innovative, IP-led company built around its proprietary POS-GRIP technology. POS-GRIP was designed to address a number of limitations associated with conventional wellhead technology particularly in terms of 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 anticipates, in due course and even more significantly, subsea. Thanks to POS-GRIP, Plexus has successfully raised wellhead test standards to equal or exceed those of premium couplings and there are numerous applications and products which the Board believes could benefit from the POS-GRIP method of engineering now and in the future.

The Company has invested in research & development and IP development in a wide range of areas and applications outside jack-up exploration, including surface production and subsea wellhead equipment, as well as proprietary connector technology. This suite of new products and applications has grown significantly and now, following a Joint Industry Project, includes: the Python™ Subsea Wellhead (a new standard for subsea wellheads - supported by BG, Royal Dutch Shell, Wintershall, Maersk, Total, Tullow Oil, eni, Senergy, and Oil States Industries Inc); the development and launch 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 new Well Tree product.

Strategy: initial focus on jack-up exploration before wider roll-out

Plexus found the oil & gas sector to be resistant to new technology and experienced push back from industry participants at the early stage of introducing POS-GRIP technology. As a consequence, Plexus took the decision to initially apply POS-GRIP technology to jack-up exploration drilling, in order to showcase and prove the technology and obtain industry acceptance, before developing and commercialising a wider range of products based on its POS-GRIP technology. The dynamics of exploration drilling enabled the Company to avoid the relatively high and often fixed costs of becoming a manufacturer, allowing Plexus to build a wellhead inventory which could be rented out to customers on a temporary basis for use on exploration drilling projects.

The Company established its position in the UKCS and ECS and became a provider of jack-up exploration drilling equipment and services, particularly for HP/HT applications. Notably, Plexus was awarded last year a £3.3m contract from Total offshore Norway for an Ultra-HP/HT exploration well called Solaris, which is believed to be one of the highest pressure wells ever drilled in the North Sea. The technical success in the North Sea has enabled Plexus to demonstrate and prove the superior qualities of its POS- GRIP technology to the wider industry.

In the period from 2005 to 2015, Plexus expanded its focus 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 wellhead exploration equipment into the Russian Federation and the other CIS states' oil and gas markets. The Company's international expansion contributed to record revenue, EBITDA, profit before tax and profit after tax being generated in the year to June 2015.

The Company's strong performance at that time was delivered despite the onset of significant challenges to the oil and gas sector, culminating in 2015 with a significant fall in the oil price from circa US$120 to US$30. As has been well documented, the sector-wide decline has continued, resulting in a sharp decline in exploration drilling activity and a dramatic reduction in capex spending across the industry. Notwithstanding this, Plexus continued to pursue its objective of developing the Company into a leading international wellhead engineering company supplying the best in class and safest wellhead equipment across exploration, production and subsea arenas, utilising its proprietary patented POS-GRIP method of engineering. Even during challenging trading conditions new customers in new territories were secured.

Favourable long terms trends

The Directors believe that long term trends within the wider oil and gas industry provide a favourable backdrop for the Company's strategy, specifically the increasing importance of gas in the hydrocarbon energy mix due to its increased accessibility and certain environmental benefits when compared to dirtier fossil fuels, such as coal and oil. For targeted reductions of CO2 emissions to be met across the globe, it is widely believed a move from dirtier fossil fuels such as coal to cleaner hydrocarbons is required. According to the BP Energy Outlook 2017, gas is the fastest growing fuel, with its share in primary energy increasing as it overtakes coal to be the second-largest fuel source by 2035 and supplies of LNG are on course to increase by 50 per cent. between 2014 and 2021. Plexus is well placed to capitalise on these trends as it believes it has the best metal to metal sealing system technology available for gas and as a result its equipment is ideally suited to the high pressures and high temperatures associated with such wells. This was demonstrated by the previously mentioned £3.3m contract from Total E&P Norge AS to supply the Solaris exploration well, a technically challenging Ultra HP/HT well offshore Norway.

Reasons for the Transaction

The growing awareness and recognition of the advantages of POS-GRIP technology, in particular for exploration wellheads, has resulted in ongoing interest and support for POS-GRIP technology from the oil & gas industry. Plexus has always worked collaboratively with the industry to convey the benefits of its technology and this approach has facilitated a relationship with TFMC which, following an extended period of due diligence, has culminated in the proposed Transaction.

In light of the significant challenges currently facing the oil & gas sector, the Board has carefully considered the timing of the Transaction and has concluded that, whilst the Company could choose to wait for the exploration sector to return to previous activity levels before redeploying its existing wellhead inventory, the timing of a recovery is uncertain. In May 2017, the Company announced that the challenging trading conditions in the sector, which have had a material impact on the performance of Plexus' core business of renting its proprietary exploration wellhead equipment, had continued in the second half of the last financial year ending June 2017. While a number of specific opportunities were being pursued in the North Sea and overseas, some of these were taking longer than anticipated to conclude as operators continue to show caution when committing to new capex and projects. It is therefore taking longer than expected to deliver on Plexus' strategy to materially expand into major markets beyond the UKCS.

The Directors believe that to conclude the Transaction at this time is advantageous to Plexus for a number of reasons. TFMC is recognised as one of the leading oil & gas service and equipment companies in the world and the Board strongly believes that TFMC will be able to use its global reach and infrastructure to grow the Jack-Up Business effectively. The Transaction also facilitates an ongoing collaboration with TFMC through the establishment of a joint steering committee that will be set up in the context of a Collaboration Agreement, which the Board believes will have the potential to enable Plexus to unlock further value of its proprietary POS-GRIP technology for the benefit of all Shareholders.

The Board of Plexus believes that to have now reached a point where the Transaction can be concluded is a significant milestone for the Company. Acceptance by the industry of the Company's POS-GRIP technology was the original strategic objective of building up the Jack-up Business and to that end it has delivered.

Under the terms of the Transaction, a three year earn-out period will provide Plexus with both earn-out revenues from the Jack-up Business and time to actively pursue additional opportunities with new and existing product lines, either on its own or with partners. The Royalty Licence will provide Plexus with an additional revenue stream based on the net sales prices of the specified M2S Crossover Production and completion equipment and the Tersus-PCT Riser Tieback equipment.

Whilst the Board anticipates that lower levels of activity in the oil and gas sector will continue, and that the timing of a recovery is difficult to predict, it is encouraging for the earn-out mechanism that there are clear signs of an improvement in exploration activity levels during the current financial year.

4. ONGOING STRATEGY FOR THE COMPANY

The Company is proprietary technology driven and its extensive patent protected IP and know-how has been successfully deployed in hundreds of wells around the world. Its superior performance, safety and operational advantages have given it an enviable position in the niche jack-up exploration market, and the Directors believe that this success could be extended to the wider energy sector including production, subsea, geothermal and fracking applications based on its POS-GRIP technology.

In line with this, the Company announced last month that it had been awarded a contract with Centrica North Sea Limited to supply its POS-GRIP 'HG' 10,000psi adjustable production wellhead for a gas production well in the UK Southern North Sea. Plexus had previously supplied Centrica with equipment for a number of exploration wells in the North Sea. This was particularly encouraging for the Company, as 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.

Outside of the Jack-Up Business, Plexus will continue to target international customers in other territories including Gulf of Mexico, India, Middle East and Russia, where it is thought there will be opportunities due to ongoing and planned drilling activity. The recent award of an exploration contract with new customer Rosneft Vietnam, a subsidiary of leading Russian oil and gas company, Rosneft is anticipated to help raise the profile of Plexus with Rosneft and other operators in Russia (which is a territory that Plexus has retained the rights to). Furthermore, the Board believes that OPEC and non-OPEC producers will want to see a return to stability and a higher oil price that can support necessary investment and planned capex, which should create additional opportunities for Plexus worldwide.

Being IP-led, Plexus does not have to support significant manufacturing operations. The Company remains in a robust financial position, with reduced capital spending commitments alongside a strong cash position and debt free balance sheet following the implementation of cash conservation measures over the last 24 months including a series of cost cutting initiatives. Despite this Plexus has continued to protect and progress the existing range of future opportunities, including continued investment in on-going research & development and POS-GRIP product extensions at a time when the industry continues to actively pursue innovative cost saving disciplines and safety driven technologies. The Company is continuously developing new technology and even when earlier patents expire the Company has an extensive body of knowledge and know-how.

The Directors will remain with the Company and a team with experience across all functions of the existing business, from engineering, research & development, technicians, quality control, HSE, project management, procurement will be retained and will enable the remaining operations to continue following completion of the Transaction and the transfer of relevant Jack-Up Business personnel from Plexus to TFMC.

The focus of the business following Completion will be:

1. Continued operation of remaining business, contracts and products

The Company will continue to focus on current projects which are not part of the Transaction, and will pursue the development of opportunities with existing products such as POS-GRIP 'HG' production wellheads.

2. Maximisation of Earn-out from the Jack-Up Business

The Company intends to prioritise the maximisation of earn-out revenues from the Jack-Up Business through the provision of, inter alia, sales and technical support to TFMC.

3. Work with TFMC through the scope of the Collaboration Agreement and the joint steering committee on key POS-GRIP products

The Company and TFMC have reviewed certain topics that can be suited for joint work under the Collaboration Agreement. Should discussions progress this could lead to further commercial IP led opportunities.

4. Design/Development of new and existing POS-GRIP products/applications

The Company has identified a number of products and applications which it believes would benefit from the integration of POS-GRIP technology. The Company intends to selectively apply its resources to capitalise on these opportunities, examples of which include:

· Existing applications of POS-GRIP 'HG' Wellheads, such as HP/HT Production Wellheads and Adjustable Production Wellheads

· New applications of POS-GRIP 'HG' Wellheads and other IP, such as land wellheads, fracking heads, geothermal systems and well abandonment and decommissioning

· Existing applications for the Python subsea wellheads system, such as Deepwater exploration drilling, and HP/HT production

· Further developments around the Python subsea system, such as Annulus Access capability and subsea Xmas Trees.

5. Research & Development

Plexus has always been an innovative IP-led business and the Board intends to devote appropriate resources to continue its ongoing innovative and proprietary technology driven approach.

5. USE OF PROCEEDS

Following completion, the Plexus Group will receive an initial payment of £15,000,000, subject to a number of adjustments described in paragraph 7 below including a deduction for expected refurbishment costs of £835,656, which along with the Plexus Group's existing cash resources of circa £7,000,000, will fund the following activities of the Plexus Group:

· commercialisation of existing and new products and technologies;

· working capital to fund new growth phase;

· expansion of engineering capabilities; and

· on-going Research & Development.

In addition to the above, the Board intends to assess the on-going capital requirements of the business and if appropriate may consider paying a proportion of the proceeds to Shareholders by way of a special dividend. The Board expects to reach a decision on this within six months of Completion and a further update will be made in due course.

Collaboration Agreement

The Company and POSL and TFMC will enter into a Collaboration Agreement on Completion which focuses on future research and development collaborations between the parties with the objective of finding new and revolutionary ways in which to apply alternative technologies to make petroleum and gas equipment safer and more efficient. The Company anticipates that the Collaboration Agreement will help identify where current technology is reaching its limitations and is no longer able to manage the increasing challenges found in the sector. The Company has introduced friction grip technology to the oilfield and applied this in ways that have significant potential for reducing risk and cost. By working in conjunction with TFMC, the Collaboration Agreement will help to identify other spaces where the application of this technology can lead to similar improvements.

The Collaboration Agreement will continue for an initial term of five years and thereafter, shall be automatically renewed without limit of period unless terminated by either the Company or TFMC giving no less than six months' notice. The Collaboration Agreement can be terminated by either party if the other party materially breaches the Collaboration Agreement, the BPA, the Royalty Free Licence or the Royalty Licence or, if the other party is subject to an insolvency procedure.

Transitional Services Agreement

The Company and POSL, pursuant to the TSA, have agreed, subject to Completion, to provide certain services on a transitional basis to TFMC and TFMC has agreed to provide certain services to the Company. The TSA will commence on the date of Completion and will continue until the earlier of (i) the longest period of time for which a service is to be provided (as specified in the TSA) or (ii) the third anniversary of Completion, subject to an extension period of 6 months to the periods set out in (i) and (ii) as agreed between the parties.

Following the first anniversary of the date of Completion, TFMC may opt to terminate the TSA, and any service provided by Plexus, upon giving Plexus six months written notice of its intention to do so. Either party may terminate the TSA if the other party fails to make payment due under the terms of the TSA or if the other party becomes insolvent, commits a material breach of the TSA which is not remedied, is subject to a change in control.
