On June 9, POET Technologies fell 8.55% in regular trading, trading at $11.21/share, with trading volume of $103 million.

On the news front, the company violated a confidentiality agreement by disclosing client contract amounts and details, prompting major customer Marvell Technology to cancel a significant order. This development poses a material impact on the company's fundamentals. As a small-cap stock, the loss of a single large-client order significantly undermines POET's revenue outlook. Marvell Technology fell 5.04% in sympathy within the optical communications sector.

The contract breach reportedly involved unauthorized disclosure of specific deal terms, resulting in Marvell's decision to terminate the order entirely rather than seek monetary damages. For POET, which had recently secured major commercial agreements to accelerate monetization of its Optical Interposer platform, this setback reverses a key growth catalyst. Additionally, the company continues to face headwinds from multiple securities class action lawsuits filed by law firms and share dilution effects from prior large-scale financing activities, further pressuring market sentiment.
