⚠ A 31% Premium Needs GrowthModerate threat

Sumitomo Corporation (8053) — threat to the moat

Sumitomo paid a 31% premium for SCSK, and the first quarter delivered 14% of the year's plan.

Sumitomo offered ¥5,700 a share for SCSK, 30.76% above the closing price of ¥4,359 on 27 October 20251. Its initial proposal had been ¥5,0502.

The price rose once before it was accepted.

A premium of that size assumes that SCSK's growth continues and that full ownership adds value, through cost savings or closer work with Sumitomo's other businesses. SCSK's record, 14 consecutive years of growth in profit and revenue3, supports the first. The second has to be earned.

The Digital AI segment's profit plan for the current year is ¥53.0 billion against ¥35.3 billion4. In the first quarter it earned ¥7.4 billion, 14% of the plan5.

The initial proposal of ¥5,050 was a premium of 10.62%6. Raising it to ¥5,700 added about ¥100 billion to the cost of the 154.7 million shares sought78. That increase has to be earned back from SCSK's growth and from whatever Sumitomo can do with full control that it could not do with half.

The measure is the segment's progress. A first half well below 40% of the plan would say the growth assumed in the price is late.
