What Is POET Technologies' Investment Narrative?

To own POET Technologies today, you have to believe that its optical interposer platform will eventually translate a long list of partnerships into meaningful, higher-margin revenue, despite the company’s tiny US$1.07 million sales base and ongoing losses. Before the latest headlines, the story leaned heavily on fast forecast revenue growth, collaborations with names like Lite-On and Lessengers, and a recent US$150 million equity raise to fund that ramp. The sudden cancellation of Celestial AI orders by Marvell and the new class action suit now cut more directly into the near term thesis, because they touch both commercial execution and governance. Short term, that makes future design wins, customer concentration and disclosure practices just as important as technology milestones and new product demos.

However, one governance issue in particular could have implications investors should be aware of. Our valuation report here indicates POET Technologies may be overvalued.
