Hisamitsu Pharmaceutical Co. said it expects to be taken private in a management buyout that values the Japanese maker of pain-relief patches at about ¥457 billion ($2.9 billion).

The offer price of ¥6,082 a share is a roughly 35% premium to Hisamitsu’s unaffected closing price on Monday, before Bloomberg reported that the company was considering a buyout.
