Nomura Holdings Inc. is considering a sale of Laser Digital Holdings AG after losses at the crypto business pushed Nomura's European operations into a loss last year. People familiar with the matter said Nomura is discussing a sale with potential buyers, including Marex Group Ltd., which is assessing the transaction. The people said no final decision has been reached, and Nomura could sell to another buyer or retain Laser Digital. Spokespeople for Nomura and Marex declined to comment.
