$WRB – Second Large Open-Market Buy From the Same 10% Holder

Another notable insider-related disclosure just hit at W. R. Berkley Corp. ($WRB).

Following the $42.5M open-market purchase disclosed earlier, Mitsui Sumitomo Insurance Co., Ltd. already a ~10% owner has returned with a second, larger add.

Latest transaction details:
• Buyer: Mitsui Sumitomo Insurance Co., Ltd.
• Shares purchased: 879,573
• Average price: $70.53
• Capital deployed: ~$62M
• Transaction type: Open market

Zooming out, this reads as repeat accumulation by the same control-capital holder, stepping back in at higher prices rather than waiting for a pullback.

Taken together, Mitsui Sumitomo has now deployed over $100M into $WRB in relatively short order.

Same buyer.
Larger size.
Higher prices.
