Sunrise Capital II’s Outsourcing Investments, Inc. acquires HamaEngineering Co., Ltd.



Tokyo – Wednesday, 28 February, 2018 – CLSA Capital Partners, the asset management business of CLSA, is pleased to announce that Sunrise Capital II’s (“Sunrise II”) portfolio company, Outsourcing Investments, Inc. (“OSI” or the “Company”), has acquired 100% of the shares of HamaEngineering Co., Ltd. (“HamaEngineering”).  Sunrise II has been the sole shareholder of OSI since its investment on 7 October, 2016.

OSI is a staffing services conglomerate headquartered in Yokohama, Japan and mainly providing tech-oriented services to blue-chip domestic manufacturers.  The Company is comprised of various subsidiaries, each exhibiting their own unique strengths. Through pursuing group-wide synergies across its subsidiaries, OSI has been able to strategically develop its business. Since its inception in 2005, OSI has continued to expand its service line-up and has been able to achieve high and sustainable growth by meeting a wide spectrum of client staffing needs. In addition, following the Global Financial Crisis, the Company has been successful in establishing a solid business foundation through diversifying the industries in which it sources its clients, enhancing its domestic-demand driven businesses and cultivating new businesses.

Since its establishment in Fukuoka prefecture in 1999, HamaEngineering has been a niche top-player specializing in the outsourcing of maintenance services for semiconductor manufacturing equipment. HamaEngineering is well regarded by clients for its strength in training skilful multi-engineers capable of handling sophisticated multi-stage production processes and various types of equipment.

Following the acquisition, OSI will be able to offer further high value-added services as a “one-stop” channel to clients in the semiconductor industry. Equally, HamaEngineering will be able to utilize OSI’s hiring and client network as well as the Company resources to enhance its hiring capability and improve operational efficiency. In the longer term, HamaEngineering will aim to provide more value-added services in upstream processes in the semiconductor business segment through further enhancing its technical capabilities and ultimately establishing itself as a “de facto standard”.

OSI aims to pursue the continuous growth of HamaEngineering while respecting its existing corporate culture. Following the transaction, HamaEngineering will retain its current CEO, Mr. Hideyo Hamamachi, and the existing management team and there will be no material change to HamaEngineering’s current business operations and company name.

Sunrise II highly values the synergies between OSI and HamaEngineering and their combined growth potential. Going forward, Sunrise II intends to provide full support to OSI and HamaEngineering in order to enhance both companies’ management framework and maximize the corporate and shareholder value.
