How a Photonics Company's Internal Failures Allegedly Destroyed Its Most Important Customer Relationship

A photonic chip packaging company cannot grow without protecting the confidential relationships that generate its revenue. POET Technologies designs optical interposer solutions for AI and data center applications. The complaint recounts that the Company generated just $2.3 million in total revenue since 2020, making every customer relationship existentially important. The lawsuit contends that internal controls failed at two critical junctures: managing confidential customer information and accurately assessing international tax obligations.

The Alleged NDA Breach That Ended the Celestial AI Revenue Stream

As detailed in the action, the Company's CFO appeared in a public social media interview on April 21, 2026 and disclosed specific purchase order details, shipping timelines, and the supplier relationship with Marvell Semiconductor (which had acquired Celestial AI). The filing states that this disclosure directly violated confidentiality obligations. On April 23, 2026, Marvell provided written notice that POET had breached its NDA. By April 27, 2026, every purchase order from Celestial AI was cancelled.

Alleged Internal Controls Failures by the Numbers

• The Company's sole meaningful near-term revenue source, Celestial AI purchase orders first disclosed in April 2023, was destroyed by the alleged NDA breach
• POET reported a net loss equal to negative 5,858% of its $2.3 million cumulative revenue since 2020
• Shares outstanding surged 303% from 38 million to 153 million between late 2022 and early 2026, underscoring the Company's dependence on equity raises rather than product sales
• The 2025 Annual Report's SOX certifications attested to disclosure of all fraud and material changes to internal controls, yet the lawsuit chronicles that management failed to prevent confidential information from being broadcast on social media
• POET's own risk factor language acknowledged the Company "may be treated as a PFIC," yet the complaint alleges this disclosure materially understated the likelihood and consequences

The Tax Compliance Gap

Separately, the action claims POET's internal processes failed to accurately assess and disclose the severity of its Passive Foreign Investment Company status. It is alleged that the 2025 Annual Report used hedging language ("we believe that we may be treated as a PFIC") when the Company's financial profile, dominated by passive income with negligible operating revenue, made PFIC classification near-certain. U.S. shareholders face punitive tax rates and compounding IRS interest when holding PFIC shares without proper elections.
