POET TECT ( $POET Tech(POET.US)) is a classic case of a single executive ruining the company.

The story is that last week, $POET Tech(POET.US)'s CFO publicly mentioned in an interview: "We are a supplier to Marvell," and even detailed the optical source orders and their uses.

The market interpreted this as positive at the time, and $POET Tech(POET.US)'s stock price surged.

However, #Marvell, which had just acquired Celestial AI, turned around and notified POET TECT to cancel all purchase orders, citing "leakage of confidential information."

$POET Tech(POET.US) confirmed the news in an announcement today, and its stock price naturally crashed 40%.

Confidentiality is a hard rule in the high-tech industry. Major clients fear their supply chains being known by competitors, which affects pricing power. They generally require strategic secrecy, thus forcing suppliers to "keep quiet."

POET's CFO's public interview essentially revealed the "cannot disclose" content from the contract. No wonder Marvell took the opportunity to cancel all orders.
