POET Technologies stock fell more than 46% after Marvell Technology cancelled all purchase orders tied to Celestial AI, citing alleged violations of POET's confidentiality obligations.
On April 23, POET got a formal notice from Marvell, which said POET had wrongly shared details about the purchase orders and shipping information, breaking confidentiality rules. Some of the canceled orders included early production units that had already been mentioned in a press release from April 2023.
