Ltd. through Establishment of a Joint Holding Company by Means of Share Transfer
Riken Corporation (hereinafter “Riken”) and Nippon Piston Ring Co., Ltd. (hereinafter “NPR”) hereby announce that,based on a Memorandum of Understanding concerning a business merger signed by the two companies on July 27, 2022
(hereinafter the “Memorandum of Understanding”), and subject to approval at shareholders’ meetings of both companies andthe approval of relevant authorities, etc., the two companies have resolved in meetings of their respective Board of Directors
convened today to enact a joint share transfer (hereinafter the “Share Transfer”) to establish (hereinafter the “Consolidation”)
NPR-RIKEN CORPORATION (hereinafter the “Joint Holding Company”), which will become a wholly owning parent
company of both companies effective October 2, 2023 (hereinafter the “Effective Date”). Moreover, the two companies have
today signed a consolidation agreement (hereinafter the “Consolidation Agreement”) grounded in a spirit of equality and1have jointly prepared a share transfer plan (hereinafter the “Share Transfer Plan”) to effect the share transfer, with details as
follows.

1. Background to and purpose of the Consolidation(1) Background to the Consolidation
Riken was established in 1927 in order to commercialize the research of RIKEN (the Institute of Physical andChemical Research), and has contributed to the development of the global automotive industry for over 90 years
through its continued study of surface treatment, processing, and materials technologies for piston rings (thecompany’s primary focus) and other parts.
Since its establishment in 1934, NPR has contributed to the development of motorization worldwide throughthe provision of high-performance, high-quality piston rings, valve seat inserts, camshafts, and other parts
primarily for use in internal combustion engines, manufactured using its own original techniques and technologies.
The automotive industry is undergoing a remarkable transformation that is said to occur only once every 100
years, and the market for engine parts is becoming clearly more challenging. However, although environmental
issues are attracting attention around the world, for the time being, the internal combustion engine will remain the
primary form of power train and both companies believe that it is their mission to develop eco-friendly engine
parts. At the same time, the companies believe it is necessary to think outside of the realm of internal combustionrelated parts and increase investment in SDGs, ESG, decarbonization, and other new areas in line with global
trends.
As the first step in development for the future, the two companies realize the need to utilize the brands they havenurtured over the years and to harness their integrated governance to promote management resource allocation andcultivate future core businesses. This will make it possible to achieve major synergy as the companies accelerate
their efforts to achieve decarbonization, and thereby allow them to evolve into a completely new business entity
capable of achieving sustainable growth and increasing corporate value.
As noted in the press release “Conclusion of a Memorandum of Understanding concerning Consolidation
through the establishment of a joint holding company (stock transfer) between Riken and NPR” dated July 27,
2022, the two companies have already discussed and examined the establishment of a Joint Holding Company bymeans of a joint share transfer based on the Memorandum of Understanding and the execution of a Consolidation.
Today, adhering to that spirit of equality, the two companies have reached a final agreement and concluded a
Consolidation Agreement under the conviction that the Consolidation is the optimal choice for the shareholders,
employees, and all stakeholders of both companies.
As noted in the press release “Notice Regarding the Schedule for the Consolidation of Riken and NPR Co.,
Ltd.,” dated November 28, 2022, due to the time and other factors required for the review of the businesscombination by the Fair Trade Commission as a prerequisite for the Consolidation, the date of the Consolidation
had been unscheduled. However, the companies submitted a notification to the Fair Trade Commission dated April
19, 2023 in accordance with the provisions of Article 15-3, paragraph 2 of the Act on Prohibition of Private
Monopolization and Maintenance of Fair Trade, and, as noted in the press release “Notice Regarding Result of the
Fair Trade Commission Review of Consolidation by Riken and NPR,” dated May 8, 2023, they have received anotice dated May 2, 2023 to the effect that the Fair Trade Commission will not issue a cease and desist order.

management resources to achieve desired synergistic effects as detailed below. By doing so, the companies seek tostrengthen the profitability of their existing businesses centered on automobile engine parts, while also
accelerating their efforts toward the creation of next-generation core products and new products in non-automotive2

engine component fields including marine vessels, hydrogen, new energy projects, thermal engineering,
electromagnetic compatibility projects, metal powder injection molded parts, medical equipment, axial gap motors(disk-shaped, thin, high-torque motors), and other fields. The two companies aim to evolve into a new company
that will lead the world in globally developing distinctive functional parts and key components through thecompanies’ proprietary technologies, further enhancing each company’s corporate value.
(i) Reinforcement of existing businesses through the reallocation of management resources, and early
development of products that will form the core of future businessIn recent years, companies in the automobile industry have been compelled to improve their technicalcapabilities and reform their organizations in response to CASE, MaaS, and other new fields of development.
Riken and NPR, too, in collaboration with research bodies and other external organizations, face the need tosecure resources to create proprietary innovation and to nurture talent that will serve as sources ofdifferentiation. Through the Consolidation, the companies aim to achieve the following:
Strengthening of cash flow creation capabilities in existing businesses

including adjustment of capital investment priorities, optimization of production over a wide range, andimproved centralization and effectiveness of development themes. Through such efforts, the companies willachieve improved profitability and strengthened cash flow creation capabilities while meeting customers’
expectations for the supply of high-quality, low-cost products.
Future core businesses and the creation of new products
Increasing business efficiency in the above-mentioned areas will enable integration of resources that had
been dedicated to the development of products for internal combustion engines and allow for a bold shift
toward future core businesses and the creation of new products. The companies will accelerate effective
investment in effective new product development, promote reciprocal integration of technologies andcorporate bases, and accelerate the development of new products that offer high added value and costcompetitiveness.
(ii) Strengthening of capabilities to respond to an increasingly decarbonizing society
Amid the global movement toward the decarbonization of society, both companies face a need to respondto global environmental issues. By bringing together and expanding their product and production
technologies, the two companies will advance their technologies in the environmental field and accelerate thedecarbonization of products. At the same time, they will aggressively work to reduce carbon dioxide
emissions throughout the supply chain and actively contribute to the creation of a sustainable society.
(iii) Reduction of costs through shared use of infrastructure and other resources
By enhancing productivity throughout the supply chain (from purchasing and production to sales), reducing
external outflow costs through standardization of internal manufacturing in both companies, reducing
procurement costs through joint purchasing, and eliminating duplication of systems and indirect operations toraise efficiency, the companies aim to enhance operational efficiency and cut costs to secure competitive
advantages.
(iv) Reduction of manufacturing costs by enhancing production efficiency through shared product integration, andtimely and appropriate fulfillment of supply responsibilities
Harnessing their technologies and infrastructures, the two companies will engage in unconventional sharedutilization of factories and optimization of production hubs, with the goal of significant productivity
improvements, enhanced capability for offering high-quality products, and reduction of fixed costs. Through3

the establishment of a sustainable production system, the companies will also fulfill their responsibilities tosupply products to customers in a timely and appropriate manner.

(2) Matters related to calculation(i) Names of valuation bodies, and their relationships with listed companies and with the two companies
Neither IR Japan nor Nomura Securities is a related party of Riken or NPR, nor does either have any
material interest of note with regard to the Share Transfer.
(ii) Overview of calculations
IR Japan calculated the Share Transfer Ratio in accordance with the market share price averaging method,
given that shares of both Riken and NPR are listed on the Tokyo Stock Exchange Prime Market and a market
share price exists for each. IR Japan also performed calculations using the comparable multiple valuation
method due to the facts that multiple listed companies exist that are comparable to Riken and NPR and that
analogizing stock prices through comparable company valuation is possible, and further performed

6

calculations using the discounted cash flow method (hereinafter “DCF method”) in order to reflect the state of
future business activities in the evaluation.
The results of calculations using the methods are as follows. The calculated range for share transfer ratio
below notes the calculated range for shares of the Joint Holding Company to be allocated per share ofcommon stock of NPR when two shares of common stock of the Joint Holding Company is allotted per shareof common stock of Riken.

With regard to the market share price averaging method, setting July 26, 2022, the business day prior to
July 27, 2022 (the date on which conclusion of the Memorandum of Understanding was announced), as
calculation reference date (i), calculation was performed of the closing stock price on calculation reference
date (i), the average closing stock price for the one-month period from June 27, 2022 to calculation reference
date (i), the average closing stock price for the three-month period from April 27, 2022 to calculationreference date (i), as well as the average closing stock price for the six-month period from January 27, 2022 to
calculation reference date (i); and, setting May 22, 2023 as calculation reference date (ii), calculation was
performed of the closing price on calculation reference date (ii), the average closing stock price for the onemonth period from April 24, 2023 to calculation reference date (ii), the average closing stock price for thethree-month period from February 24, 2023 to calculation reference date (ii), as well as the average closing
stock price for the six-month period from November 24, 2022 to calculation reference date (ii).
In calculating the above share transfer ratio, IR Japan used information provided by both companies,
publicly available information, etc., doing so under the assumption that all of the materials, information, etc.
are accurate and complete and without conducting independent verification of the accuracy or completenessof these. With regard to the assets and liabilities of the two companies and their affiliates (including financial
derivatives, off-the-book assets and liabilities, and other contingent liabilities), independent valuation,
appraisal, or assessment was not performed, including analysis and valuation of individual assets andliabilities, and appraisal and assessment by a third party was not requested. IR Japan’s calculation of the sharetransfer ratio incorporates information and economic conditions up to the date of May 22, 2023. Financial
projections and other forward-looking information concerning Riken was rationally prepared on the basis ofbest-effort and good-faith forecasts and judgments currently available to the management of Riken. Financial
projections and other forward-looking information concerning NPR was rationally examined and confirmedon the basis of best-effort and good-faith forecasts and judgments currently available to the management of
NPR. IR Japan’s calculation of the Share Transfer Ratio assumes that the financial status of Riken and of
NPR will change in line with these forecasts.
The business plans of Riken and NPR, used by IR Japan as premises for calculation under the DCF
method, do not incorporate synergies resulting from the Consolidation. The business plans of Riken and NPR
for the period from the fiscal year ending March 31, 2024 to the fiscal year ending March 31, 2026, used by
IR Japan as premises for calculation under the DCF method, include fiscal years in which significant
fluctuations in profit are anticipated. Specifically, Riken is expected to achieve a significant increase in profit
for the fiscal year ending March 31, 2025, mainly attributable to passing through of increases in procurement
costs, such as raw material costs, energy prices, and outsourcing costs, to sales prices, and corporate efforts
such as rationalization activities. Moreover, NPR is expected to achieve a significant increase in profit for the
fiscal year ending March 31, 2024, with a contribution to earnings form the passing through of procurement
costs to sales prices and corporate efforts.

With regard to the market share price averaging method, setting July 26, 2022, the business day prior to
July 27, 2022 (the date on which conclusion of the Memorandum of Understanding was announced), as
calculation reference date (i), calculation was performed of the closing stock price on calculation reference
date (i), the average closing stock price for the five-day period from July 20, 2022 to calculation reference
date (i), the average closing stock price for the one-month period from June 27, 2022 to calculation reference

calculation reference date (i); and, setting May 22, 2023 as calculation reference date (ii), calculation was
performed of the closing price on calculation reference date (ii), the average closing stock price for the fiveday period from May 16, 2023 to calculation reference date (ii), the average closing stock price for the onemonth period from April 24, 2023 to calculation reference date (ii), the average closing stock price for thethree-month period from February 24, 2023 to calculation reference date (ii), as well as the average closing
stock price for the six-month period from November 24, 2022 to calculation reference date (ii).
In calculating the above share transfer ratio, Nomura Securities used information provided by bothcompanies, publicly available information, etc., doing so under the assumption that all of the materials,
information, etc. are accurate and complete and without conducting independent verification of the accuracy
or completeness of these. With regard to the assets and liabilities of the two companies and their affiliates(including financial derivatives, off-the-book assets and liabilities, and other contingent liabilities),
independent valuation, appraisal, or assessment was not performed, including analysis and valuation ofindividual assets and liabilities, and appraisal and assessment by a third party was not requested. Nomura
Securities’ calculation of the share transfer ratio incorporates information and economic conditions up to thedate of May 22, 2023. Financial projections and other forward-looking information concerning NPR was
rationally prepared on the basis of best-effort and good-faith forecasts and judgments currently available to the
management of NPR. Financial projections and other forward-looking information concerning Riken wererationally examined and confirmed on the basis of best-effort and good-faith forecasts and judgments
currently available to the management of Riken. Nomura Securities’ calculation of the Share Transfer Ratio
assumes that the financial status of NPR and of Riken will change in line with these forecasts.
The business plans of NPR and Riken, used by Nomura Securities as premises for calculation under the
DCF method, do not incorporate synergies resulting from the Consolidation. The business plan of NPR fromthe fiscal year ending March 31, 2024 to the fiscal year ending March 31, 2026, used by Nomura Securities as8

premises for calculation under the DCF method, includes a business year in which a significant increase inprofit is anticipated. Specifically, in the fiscal year ending March 2024, a significant year-on-year increase inprofit is expected as the company’s efforts to pass though procurement costs to sales prices contribute toearnings. Furthermore, the business plan of Riken from the fiscal year ending March 31, 2024 to the fiscal
year ending March 31, 2026, used by Nomura Securities as premises for calculation under the DCF method,
includes a business year in which a significant increase in profit is anticipated. Specifically, in the fiscal year
ending March 31, 2025, Riken is projected to achieve a significant increase in profit from the previous fiscal
year, mainly attributable to the passing through of increases in procurement costs, such as raw materials costs,
energy prices, and outsourcing costs, to sales prices and corporate efforts such as rationalization activities.
(3) Matters concerning application for listing of the Joint Holding Company
Riken and NPR plan to apply for a new listing (technical listing) on the Tokyo Stock Exchange Prime Market
for shares of the established Joint Holding Company. The date of listing is scheduled for October 2, 2023, theregistration date for establishment of the Joint Holding Company.
Through the Share Transfer, Riken and NPR will become wholly owned subsidiaries of the Joint Holding
Company, and, in accordance with the listing of the Joint Holding Company, are scheduled to be delisted effective
September 28, 2023. If listing of the Joint Holding Company is approved, the shareholders of Riken and NPR will
be able to trade shares of the Joint Holding Company granted through the Share Transfer on the Tokyo Stock
Exchange.
Common stock of NPR is currently listed on the Tokyo Stock Exchange Prime Market. As the stock does notmeet the criterion for market capitalization of tradable stock included among the criteria for maintaining listing insaid market, on November 29, 2021 the company submitted a Plan for Meeting the Criteria for Maintenance ofListing in the New Market Segment (hereinafter the “Plan”) and has been subjected to the application of interim
measures. It is assumed at present that the market capitalization of tradable stock of the Joint Holding Company
scheduled to be listed will satisfy the above criteria. While the Plan is on hold pending the condition that the above
technical listing application is approved by the Tokyo Stock Exchange, the company will continue striving toenhance its corporate value in accordance with the aims of the plan.
