POET market cap halves after CFO unauthorized Marvell order disclosure triggers $5M cancellation

The U.S. equity market recently shed its sluggishness to reach new highs, with AI-related equities leading the charge as NVIDIA achieved a market capitalization of $5.26 trillion. Sectors including optoelectronics, power chips, and HBM memory experienced significant appreciation, mirroring the cryptocurrency market's dynamic where small-cap stocks surged from single digits to tens of dollars based on compelling narratives.

However, this trend faced a violent correction with POET, a Toronto-based firm specializing in Optical Interposers, which serves as a critical substrate for interconnecting electronic and photonic chips on silicon wafers. This technology is a highlighted layer in the NVIDIA-Marvell co-packaged optics roadmap, enabling lightning-fast data transmission between GPUs in AI data centers. Despite the technical promise, POET's financial reality remained stark, with full-year 2025 revenue of $1.07 million against a net loss 5858 times that figure. Cumulative revenue from 2020 to present totaled only $2.34 million, while capital raises via additional offerings reached nearly $538 million, causing a 303% share dilution from 38 million to 153 million shares. Data compiled by Woofun AI shows that despite these fundamentals, the stock surged 847% from $0.93 in early 2024 to $8.82 in October 2025, fueled by Korean retail investors touting it as a hidden gem in KakaoTalk groups.

The narrative unraveled on April 14 when short-seller Wolfpack Research released a report alleging stock promotion and tax misclassification. The report detailed how POET paid LFG Equities $95,000 to subcontract YouTube influencers, resulting in three videos reaching 760,000 subscribers posing as independent investors.

Concurrently, a Cayman fund, MMCAP, executed a discounted private placement at $5.50 per share on October 7, 2025, only to sell approximately 5.8 million shares within 24 hours, reducing its stake from 16.2% to 9.99%. Wolfpack analysis of 41 similar small-cap stocks revealed a median price drop of 92% from highs. More critically, the firm argued POET qualified as a Passive Foreign Investment Company (PFIC) under U.S. tax law, given that 80.9% of its 2025 income derived from passive sources like interest, with $4.55 million in interest income versus $1.07 million in operating revenue. With $313 million in cash representing over 95% of assets, the PFIC classification would force retail investors to pay a 37% tax on annual paper gains. Woofun AI notes that the timing was strategic, with the report released just 28 hours before the April 15 tax deadline, forcing POET to acknowledge its PFIC status and announce a domicile relocation from Canada to the U.S.

The situation escalated unexpectedly on April 21 when POET CFO Thomas Mika appeared in a Stocktwits video interview to refute the short-seller report. Mika labeled the short sellers "maggots" and asserted the company held $430 million in cash with real customers. In a pivotal moment, he personally confirmed a $5 million purchase order from Celestial AI, a division of Marvell, with shipments scheduled to begin that quarter. The market reacted instantly, with POET surging 19.32% on April 21 and another over 20% in pre-market trading on April 22. Influencer Serenity posted on X that the confirmation of a direct Marvell supply relationship prompted a market reassessment of POET's position in the optical communication roadmap.

However, this unilateral disclosure violated standard semiconductor industry confidentiality agreements, which strictly govern the sharing of customer roadmaps, order amounts, and specifications to protect downstream bargaining power. Woofun AI analysis suggests that such breaches are often fatal to supplier relationships in the tightly integrated AI hardware ecosystem.

On April 23, Marvell formally notified POET in writing that all purchase orders were canceled due to the breach of confidentiality obligations, including initial volume production orders dating back to April 2023. This single interview effectively wiped out a three-year partnership. Despite receiving the cancellation notice on April 23, POET failed to disclose the material event promptly as required by public company regulations. The stock dropped 8% at the open on April 23, interpreted by the market as a normal correction, and rose another 28% on April 24. Throughout the weekend, retail investors remained optimistic, unaware that the order had been formally voided. The company remained silent for nearly four trading days until April 27, a delay that Critini Research analyst Jukan noted could expose the firm to litigation from shareholders who bought at the peak. On Monday pre-market, the disclosure of the order cancellation sent shockwaves through the market, revealing that Celestial AI had terminated all agreements citing the violation of confidentiality regarding shipment details.

The market reaction was severe and immediate. At the opening bell on April 27, POET plummeted nearly 46%, followed by a further 10% drop in after-hours trading, evaporating almost half of its market value in a single day. Serenity observed that Marvell's cancellation logic extended beyond the confidentiality breach; POET's role involved encapsulating lasers from other manufacturers into Marvell's silicon photonics, a segment vulnerable to vertical integration. Marvell could have directly procured from laser suppliers like Lumentum and handled packaging internally, using the confidentiality incident as a catalyst to accelerate this strategic shift. The true message conveyed was that Marvell no longer required POET's services. The sharp decline also dragged down upstream supply chain peers, with laser suppliers SIVE, LITE, and LPTH collectively falling as the market re-evaluated the sector's beta exposure. This episode underscores a recurring pattern in the U.S. stock market where companies replicate crypto trading strategies: riding trends, crafting narratives, engaging KOLs, inflating prices, and dumping shares under the guise of negative news. The CFO's rant against short sellers ultimately attracted lawsuits and secured a victory for the shorts, highlighting the fragility of governance in speculative AI small-caps.
