Dear Sirs/Madams,ENEOS NUC Corporation

Increase in Production Capacity ofExtra High Voltage and High Voltage Power Cable Insulation
ENEOS NUC Corporation (Representative Director and President: Eiichiro Kitahara) is pleased toannounce that we are investing in a compound production facility that will increase our annual
production capacity of XLPE Power Cable Insulation and Semiconductive Power Cable Shields foruse in insulating extra high voltage and high voltage power cables to roughly 30,000 tons starting fromDecember 2023.

Solar power generation, offshore wind power generation, and other renewable energy sources arebeing introduced through plans to decarbonize and initiatives aimed at achieving SDGs in nations
around the world, especially in Europe, and development of these energy sources has accelerated inrecent years. Against this backdrop, there is expected to be a worldwide increase in demand for extra
high voltage and high voltage power cables for use as transmission lines, and accompanying this, there
is also a rapid increase in demand for XLPE Power Cable Insulation for use on underground powertransmission lines. In addition, inter-regional power transmission networks are already underconstruction in Europe, and future networks are being considered in Japan and other parts of Asia, sodemand for power transmission lines is also expected to further increase.
For society as well, these power lines are an important element of infrastructure. They require anextremely high level of reliability, and Japanese technology is highly regarded as among the best inthe world.
For more than 30 years, we have been developing, producing and selling XLPE Power Cable
Insulation for use on extra high voltage and high voltage underground power lines, an importantelement of infrastructure, and we were the first in the world to begin selling XLPE Power Cable
Insulation for 500kV underground power transmission lines, the highest AC voltage. We are highly
regarded as a top-class manufacturer by power line companies around the world due to the excellent
quality and performance of our products as well as our track record in long-term use.
Due to year after year of R&D and quality improvement in addition to our track record ofachievements, our XLPE Power Cable Insulation is held in high regard globally as one of the highestclass materials in the world for its excellent insulating properties, extremely high level of cleanliness,and excellent power cable possibility, and it is used on extra high voltage and high voltage power
cables in many countries, primarily in Asia. In recent years, we have also received requests from
European power cable manufacturers for deliveries of this material.
In order to meet this growing demand for our XLPE Power Cable Insulation, which is backed byrequests for increased supply from major power cable companies around the world, we have decided
to open the most up-to-date facility to increase our production capacity of XLPE Power Cable
Insulation for use on extra high voltage and high voltage power cables to roughly 30,000 tons annually.
The new facility is an investment of roughly 12 billion yen, and we plan to construct it within thegrounds of our Kawasaki Plant. The new facility will be completed in July 2023, and product sales arescheduled to commence from December 2023.
Centered on this expansion of facilities and our XLPE Power Cable Insulation for use on DCextra high voltage and DC high voltage power cables, which we released commercially in 2020, wewill play an important role in the XLPE Power Cable Insulation market in Japan, in Asia, and in theworld. We aim to contribute to the construction of future social infrastructure by continuing to deeply
examine supply systems in line with advancing technical developments and market growth.
In addition, as a member of the ENEOS Group, we are promoting business activities based on
special technological products. We expect that this expansion of facilities will greatly contribute to thespread of renewable energy sources, which are on the rise worldwide.
