Profit rising on acquisitions.

Net One Systems added network integration to SCSK's systems integration. The company describes the combination as a differentiated position as a systems and network integrator3.

Acquisitions of this kind carry integration costs. The company recorded about ¥2 billion of costs related to Net One Systems in the latest year4.

The acquisition was completed through a tender offer on 25 December 20245, a year before Sumitomo's own offer for SCSK. The sequence let SCSK complete a major deal as a listed company before its parent took it private.

The measure is SCSK's growth after the combination. Its record of 14 consecutive years of growth6 continuing through the integration would show the purchase adding rather than distracting.

Moat trajectory: Widening

The combination broadens SCSK's services.
