Poet Technologies Stock Plunges 47% After Marvell Cancels AI Orders

Poet Technologies stock plunged more than 47% in a single session after the company disclosed that Marvell Technology had cancelled key purchase orders tied to an artificial intelligence partnership, marking one of the steepest declines in the company’s trading history, according to MarketWatch.

The sharp selloff erased gains from a recent rally that had pushed the stock to a multiyear high of $15.50 just days earlier, underscoring the volatility surrounding AI-linked semiconductor plays and the sensitivity of valuations to partnership developments.

Poet Technologies Stock Performance and Market Reaction

Shares of Poet Technologies fell more than 47% following the disclosure, representing a record-breaking drop for the company. The selloff came abruptly after a strong upward movement in the previous week, when investor optimism around artificial intelligence demand had driven the stock to its highest level in years.

The sudden reversal reflects how quickly sentiment can shift in high-growth technology segments, particularly when dependent on a limited number of strategic partnerships or customers.

Marvell Technology’s stock also declined, falling 3.71% during the same period, indicating broader investor concern over the implications of the development across the semiconductor and AI supply chain ecosystem.

The decline followed Poet Technologies’ announcement that Marvell had cancelled all purchase orders associated with the company’s collaboration involving Celestial AI. The cancellation notice was formally issued on April 23.

Marvell, which recently acquired Celestial AI, cited alleged breaches of confidentiality by Poet Technologies as the reason for terminating the agreements. The cancellation effectively ends a key commercial relationship tied to AI-related product development and deployment.

The termination of these orders represents a significant setback for Poet Technologies, as the partnership had been positioned as a critical component of its growth strategy within the artificial intelligence infrastructure market.

Impact on AI and Semiconductor Positioning

The development highlights the risks associated with emerging AI supply chains, where companies often rely on a small number of high-value contracts to drive revenue growth and investor confidence.

Poet Technologies had been benefiting from increased market attention on AI hardware and optical interconnect solutions, which are seen as essential for scaling data center performance. The cancelled orders, however, raise questions about the company’s near-term commercial pipeline and execution capabilities.

Marvell’s acquisition of Celestial AI further complicates the situation, as it consolidates control over the partnership ecosystem and allows the larger chipmaker to reassess supplier relationships and strategic priorities.

The nearly 50% decline in Poet’s share price reflects heightened investor sensitivity to governance issues, particularly those involving confidentiality and contractual compliance. Allegations of breaches can significantly alter the risk perception of a company, even in the absence of detailed disclosures.

The episode also illustrates the broader volatility in technology equities linked to artificial intelligence, where valuations can be driven as much by expectations and partnerships as by current financial performance.

Market participants have increasingly scrutinised smaller semiconductor and AI infrastructure firms for their dependency on a narrow client base, making them vulnerable to abrupt changes in business relationships.

Recent Trading Context and Outlook

Prior to the announcement, Poet Technologies had experienced a rapid surge in its share price, reflecting strong investor interest in companies positioned within the AI ecosystem. The rally pushed the stock to a multiyear high of $15.50, indicating elevated expectations for future growth.

The subsequent collapse highlights the fragile nature of such momentum-driven gains, particularly when tied to unconfirmed or evolving commercial arrangements.

As of the latest update, the company has not disclosed additional financial details regarding the value of the cancelled purchase orders or the potential impact on revenue. The absence of such data leaves uncertainty around the scale of the financial implications.

The situation remains fluid, with investors closely monitoring any further disclosures from both Poet Technologies and Marvell Technology regarding contractual obligations, potential disputes, or alternative partnerships.
