POET Technologies Faces Fraud Investigation After Shares Plunge 49 Percent
Boston, Monday, 27 April 2026.
On April 27, 2026, POET Technologies’ shares plummeted 49 percent after a major client canceled orders, prompting a critical securities fraud investigation that highlights significant risks for tech investors.
The Catalyst Behind the Collapse
The immediate trigger for the massive sell-off occurred when Marvell Technology Inc., which had recently acquired Celestial AI, provided written notice on April 23, 2026, canceling its purchase orders with POET Technologies [1]. This development was a devastating blow, as POET had previously touted initial production orders from Celestial AI dating back to April 2023 [1]. The market reaction on Monday, April 27, 2026, was swift and brutal. POET shares trended down by 48.35 percent intraday, opening near $9.57 and ultimately closing at $7.79 [2]. This represented a catastrophic collapse of -49.742 percent from its intraday peak of $15.50 just days prior on April 24 [2].
Fundamentals Versus Meme Momentum
Beneath the surface of POET’s recent stock surges lay a highly speculative financial foundation. The company reported roughly $1.1 million in revenue against cumulative losses of approximately $76.8 million [2]. While the firm maintains a 100 percent gross margin and holds about $40 million in cash with a current ratio of roughly 2.2, it suffers from negative cash flow and a staggering price-to-sales ratio exceeding 2,100x [2]. Such metrics highlight a severe disconnect between the company’s market capitalization and its actual operational output.
Falling Behind in the AI Optics Race
POET had been attempting to position itself within the booming artificial intelligence infrastructure market, currently assembling approximately 1,000,000 optical devices per month with ambitions to scale up to 10,000,000 units [3]. Yet, even before the catastrophic order cancellation, POET was vastly underperforming its sector peers. While POET’s stock had risen 272 percent over the past year, competitors such as Applied Optoelectronics (AAOI) and Lumentum Holdings (LITE) surged by 1,168 percent and 1,400 percent, respectively [3].
Legal Repercussions and Next Steps
The stark contrast between POET’s promotional momentum and its fundamental reality is now the focal point of Block & Leviton’s legal inquiry [1][2]. The securities class action firm, which has a history of recovering billions of dollars for defrauded investors, is rigorously probing the timeline and disclosures surrounding the Celestial AI contract cancellation [1]. The core of the investigation will likely center on when POET executives knew about the deteriorating relationship with Marvell Technology and whether that material information was delayed or withheld from the public markets [alert! ‘Specific focus of the investigation is inferred based on standard securities fraud probes regarding undisclosed material information’].
