POET Technologies Inc

POET Technologies has seen its stock fall roughly 29% over the past month, driven by multiple lawsuits regarding the company's tax status and the cancellation of purchase orders by Marvell associated with Celestial AI. Earlier in May, the stock was trading near an all-time high of around $20, and Wall Street still expects more than 100% upside over the next 12 months. In the same month, the company signed a supply agreement with Lumilens to jointly develop an Electrical-Optical Interposer, a new optical interconnect technology aimed at solving a growing bottleneck in AI infrastructure. As part of the deal, Lumilens placed an initial $50 million purchase order with POET, with the potential to grow to over $500 million over five years, and POET granted Lumilens warrants to purchase shares.
