Notice Concerning Execution of Basic Agreement on Business Integration of

Minebea Co., Ltd. and MITSUMI ELECTRIC CO., LTD.

Minebea Co., Ltd. (“Minebea”) and MITSUMI ELECTRIC CO., LTD. (“MITSUMI”) resolved at their respective meetings of their board of directors held today to enter into a basic agreement (the “Basic Agreement”) to proceed with a discussion and consideration of a business integration (the “Business Integration”) based on the spirit of equal partnership, as follows. 

1.  Background and Purpose of the Business Integration

(1) Background of the Business Integration

Minebea was incorporated in 1951 as Japan’s first specialized manufacturer of miniature ball bearings, and since then, it has manufactured large numbers of bearings and other high-quality and high-precision parts.  In recent years, it has also manufactured and sold liquid crystal backlights employed in smartphones, lighting devices and other products.  Furthermore, it has adopted five principles as its corporate motto, which are to “be a company where our employees are proud to work,” “earn and preserve the trust of our valued customers,” “respond to our shareholders’ expectations,” “work in harmony with the local community” and “promote and contribute to global society.”  Under this corporate motto, Minebea’s basic management principle has been to fulfill its social responsibilities to the various stakeholders—such as shareholders, business partners, local communities, employees and society—and maximize its corporate value.  In accordance with this management principle, the Minebea Group sees as its challenge working to boost the earnings capacity of its existing lines while developing new high-value-added products, and leveraging the wealth of experience it has gained in manufacturing, sales, engineering and development as well as the commitment to restructuring its business portfolio, encompassing the hybrid component business that is driven by its combined technological strengths in electronic devices and components as well as machined components, in order to provide flexible prices and meet the needs of its customers.  The Minebea Group seeks to actively work on restructuring its business portfolio and increasing corporate value via M&As and alliances.  At the same time it seeks to focus on establishing large-scale overseas mass production facilities as well as R&D capabilities in light of regional risk assessment findings.

MITSUMI was established in 1954 as a manufacturer of electronic components, such as coils and transformers.  Since then, starting from the introduction of Polyvaricons (variable condenser) to the world in 1955, it has developed world-leading technical capabilities and has offered high-precision, high-quality electronic components with stable performance, excellent reliability and durability for cutting-edge electronic components all over the world during various periods of history. Currently, it manufactures and sells electrical and communication equipment, such as mechanism components, semiconductor devices, power supply parts, high-frequency devices and optical devices, for various electronic devices and products, such as data communication devices, automobiles, healthcare and consumer electronics, other leisure devices, televisions and digital cameras. Recently, in the electronic component industry, the market for data communication devices, such as smartphones and tablet PCs, has been growing and the in-car product market has continued to expand due to increasing installations of electrical devices in automobiles, while the market for PCs, digital cameras and leisure-related products have been sluggish. In such environment, MITSUMI has been competing based on its high technological skills, such as the world’s first mass production of high-performance actuators for cameras, secondary battery-related semiconductors and charger adapters, and creating seeds of various new businesses, but MITSUMI recognizes that its business challenge is a shortage of management resources for the expansion of existing businesses and expansion into new businesses.

Both companies had considered business alliance, including integration with other companies, in order to realize further continuous growth and acceleration of development, as well as addressing their respective challenges in their business areas with the aim of enhancing performance and improving corporate value.  As a result, both companies came to recognize that despite both operating in a similar industry, they were not competing much against each other but rather had different sources of competitiveness, and that they would be able to generate significant synergies in terms of mass production, sales, procurement and product development through full-scale collaboration.  In particular, the companies believe that linking MITSUMI’s various developing technologies and products to Minebea’s in-house manufactured assembly equipment, mold design, manufacturing capacity and mass-production capacity of overseas factories would likely lead to expansion of customer base and sales, reduction of manufacturing cost, the introduction of innovative products, provision of innovative solutions and other benefits.  Under such circumstances, both companies came to share a common perception through mutual discussions that, in order to maximize their corporate value, it would be in the best course of action to aim to become a genuine solutions company by combining analog and digital technologies.  Both companies therefore agreed to proceed with a discussion and consideration towards the realization of a business integration based on the spirit of equal partnership.

(2) Purpose of the Business Integration

Through the Business Integration, the two companies will aim to become a genuine solutions company by realizing synergies of integration described below, and will further improve their corporate value as an electro mechanics solutions company.

(i) Growth and evolution of business portfolio

The two companies will aim for growth by increasing cross-selling, such as the strengthening of customer base through the expansion of sales of MITSUMI’s in-car products into Minebea’s sales channel.  The two companies will also aim for strategic evolution of the business portfolio that captures the needs of the IoT era by concentrating resources in the high-end and niche markets as well as combining MITSUMI’s product portfolio comprising input, conversion and control devices, such as switches, sensors and connectors, and Minebea’s product portfolio comprising output devices, such as motors and actuators.

(ii) Enhancement of cost competitiveness and capacity to generate cash flow by optimizing manufacturing structure and bases

The two companies will aim for enhancement of cost competitiveness and capacity to generate cash flow by achieving lower fixed costs through, among others, significant improvement in productivity by reallocating manufactured goods and by reducing variable costs through the promotion of large-scale and joint procurement of materials and parts, as well as by proceeding with the mutual utilization of each other’s factories and optimization of manufacturing bases of Minebea and MITSUMI.

(iii) Enhancement of development capabilities and provision of solutions

The two companies will aim for a corporate structure that enhances their development capabilities that enable them to create unique products and provides solutions by gathering both companies’ technological capabilities, such as expansion of Minebea’s smart city business through the application of MITSUMI’s wireless technology, use of MITSUMI’s power source technology in SALIOT (Smart Adjustable Light for IoT), utilization of SALIOT as a surveillance camera that employs MITSUMI’s camera module and image processing technology, sharing of both companies’ motor technologies and generation of synergistic effects resulting therefrom, development of the HUD (Head-Up Display) system that combines Minebea’s glass technology (J3DD) – such as microoptical element technology and concave mirrors – and MITSUMI’s MEMS-type PGU (Picture Generation Unit), and expansion of business to robot-related products and other high-value-added product areas through the application of Minebea’s molds and high-precision processing technology to MITSUMI’s products.

2.  Outline of the Business Integration

(1) Method of the Business Integration

Minebea and MITSUMI will conduct a share exchange (the “Share Exchange”) subject to obtaining the approval of shareholders of MITSUMI at its general meeting of shareholders to be held in December 2016 and obtaining regulatory approvals required for the Business Integration and other requirements. Specifically, shareholders of MITSUMI will be allotted shares of Minebea (whose company name is planned to be changed to MINEBEA MITSUMI Inc. (“MINEBEA MITSUMI”) subject to obtaining the approval of shareholders of Minebea).

The two companies plan to conduct, as soon as reasonably possible after the effective date of the Share Exchange, a reorganization, including shifting

MINEBEA MITSUMI to a holding company structure in which MITSUMI will remain a corporate entity, by, among others, transferring  MINEBEA MITSUMI’s existing business through a company split to MITSUMI or MINEBEA MITSUMI's wholly-owned subsidiary to be newly established.  The two companies will continually discuss and determine the details, including specific method of reorganization and timing, by taking into account how they can maximize synergy effects and optimize the management structure for the business following the Business Integration.

Additionally, if it is found through due diligence and other similar work to be conducted in the future that practical problems will occur in connection with utilizing the share exchange method, the two companies may use an alternative method based on mutual discussion and consideration.

(*1) The company name will be changed from Minebea Co., Ltd. subject to obtaining the approval of shareholders of Minebea.

(*2) The companies are planning to shift MINEBEA MITSUMI to a holding company structure in which MITSUMI will remain a corporate entity by, among others, transferring MINEBEA MITSUMI’s existing business through a company split to MITSUMI or MINEBEA MITSUMI’s wholly-owned subsidiary to be newly established.
