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

Ninth Well Order Signed with Det norske - Norway

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 that it has received its ninth purchase order ('PO') since 2012 from Det norske oljeselskap ASA ('Det norske') to supply surface wellhead and mudline equipment services for the Langfjellet standard pressure exploration well on the Norwegian Continental Shelf, offshore Norway. The value of this order is estimated at approximately £0.6 million with revenues expected to commence in August 2016.

Under the terms of the PO, Plexus will supply its 18-3/4" 15M surface wellhead and mudline system. The well will be drilled using the Maersk Interceptor Jackup (XLE) class rig, which is expected to take circa 40 days.

Plexus' CEO Ben Van Bilderbeek said, "This agreement follows swiftly on the heels of our recent Russian strategic initiative aimed at expanding our offering into new territories. Whilst global markets, including Russia and China, are expected to play a key role in Plexus' growth strategy, our dominant position in the North Sea jack-up exploration sector and its scope for generating future business opportunities should not be ignored in view of the many billions of barrels of oil and gas equivalent that are still to be extracted. We value Det norske's business and hope to be working with them in the North Sea for many years to come as we continue to position ourselves throughout the current down cycle to become a leading supplier of superior, best in class wellhead and mudline suspension equipment for exploration and production applications across the world."

NOTES:

Plexus Holdings PLC

Plexus Holdings PLC, which began trading on AIM in December 2005, is an oil and gas engineering and services business, which supplies wellhead and mudline suspension equipment together with associated equipment and services for exploration and production applications. Based in Aberdeen, with offices in London, Cairo, Kuala Lumpur, Singapore and a presence in Houston, Texas, it has developed and patented a friction-grip method of engineering for oil and gas field wellheads and connectors, POS-GRIP®, which involves deforming one tubular member against another to effect gripping and sealing.

The Company plans to accelerate the roll out of POS-GRIP wellhead equipment as a superior alternative to current technology and for it to become the future industry standard for wellhead design. In particular, the technology has advantages in High Pressure/High Temperature (HP/HT) and Extreme HP/HT (X-HP/HT) oil and gas environments, for which there is growing global demand and where Plexus is being increasingly recognised as the supplier of choice.

To date, POS-GRIP wellhead systems have been used or selected to be used in over 350 oil and gas wells by international companies including ADTI, AGR, Apache Energy Australia, BHP Billiton, BG International, BP, Brunei Shell Petroleum, Cairn Energy, Centrica, ConocoPhillips, Dana Petroleum, Dubai Petroleum, ENI, GDF SUEZ, Global Santa Fe, Maersk, Niko Resources, Petro-Canada Trinidad & Tobago, Premier Oil Norge, Red Sea Petroleum Operating Company, Repsol, RWE, Senergy Limited, Shell China, Shell Egypt, Statoil, Silverstone Energy, Talisman Energy, Total, Tullow Oil, and Wintershall.

Importantly, the Company is focussed on extending its proprietary POS-GRIP technology into an increasing number of subsea applications. In line with this, in March 2011 the Company launched a Joint Industry Project ('JIP') initiative to develop a new subsea wellhead design, the 'Python Subsea Wellhead' utilising its friction-grip technology in collaboration with key oil and gas operators and service companies. BG, Royal Dutch Shell, Wintershall, Maersk, TOTAL, Tullow Oil, ENI, Senergy, ADTI and Oil States Industries Inc. The JIP is nearing completion with final qualification testing of all key features of the product under way, and the resultant Python Subsea Wellhead design will include a combination of key features never before seen in a subsea wellhead which include being rated to 15,000 psi, 4,000,000 pounds of 'instant' casing lockdown capacity, and importantly rigid metal annular seal technology qualified to match the performance of premium connectors. The building of a single string Python Subsea Wellhead system prototype commenced in February, and was launched at the SPE Offshore Europe Exhibition and Conference in Aberdeen ('OE2015') in September 2015.

Plexus is an innovative technology company always looking for opportunities to apply its proprietary POS-GRIP friction grip method of engineering to new products both within and outside the oil and gas industry. For example Plexus have recently completed a JIP in conjunction with Maersk to develop a downhole HPHT Tieback connector which for the first time allows the reconnection of production casing to HPHT exploration and production wells. In addition the Company has developed and qualified a new product called POS-SET Connector™ which is designed to re-establish a connection onto rough conductor casing previously cut above the seabed to facilitate tieback or abandonment operations. The market for permanent plugging and abandonment of wells is increasing in the North Sea and beyond, and could be an important new revenue stream for the Company.
