• In late April 2026, Marvell Technology cancelled purchase orders tied to POET Technologies’ work with Celestial AI, citing alleged breaches of confidentiality obligations.

What Is POET Technologies' Investment Narrative?

To own POET Technologies today, you have to believe its Optical Interposer platform can eventually translate a growing list of collaborations into meaningful, recurring revenue, despite the company still generating only about US$1.07 million in sales and a US$62.96 million loss in 2025. The Marvell cancellation is a sharp reminder that the near term story is still about proof-of-execution, customer diversification and access to capital, rather than steady fundamentals. In the short run, investors will likely focus on whether POET can firm up other commercial relationships, such as with Lite-On and Lessengers, and convert OFC 2026 product demos into tangible orders that offset the setback. At the same time, the recent 47 percent single-day share price drop crystallizes key risks around contract concentration, volatility and further equity dilution if cash needs rise.

But this dependence on a few counterparties is something investors should be very aware of. Our expertly prepared valuation report on POET Technologies implies its share price may be too high.
