Key Dates and Disclosure Events Shareholders Need to Know: From Phantom Deals to a 36.8% Stock Collapse, the SES AI Timeline Exposes an Escalating Pattern of Alleged Misrepresentation
NEW YORK, May 20, 2026 /PRNewswire/ -- Levi & Korsinsky, LLP encourages investors who suffered losses in SES AI Corporation (NYSE: SES) to contact the firm.

Levi, Esq. at jlevi@levikorsinsky.com or (212) 363-7500.
SES shares lost $0.63 per share, a 36.8% single-day decline, closing at $1.08 on March 5, 2026 after corrective disclosures shattered the narrative the Company had built over the preceding fourteen months. The window to apply for lead plaintiff closes on June 26, 2026.
Chronology of Material Events
The securities action against SES AI traces a series of dated events that, the lawsuit contends, collectively reveal how a misleading growth story was constructed and ultimately collapsed.
January 29, 2025 — The AISPEX Announcement
SES AI issued a press release touting a non-binding MOU with AISPEX targeting up to $45 million in battery energy storage revenue. As alleged, AISPEX lacked meaningful crypto mining operations in Texas. A subsequent investigation found its listed headquarters occupied by a different company, surrounded by shipping containers.
February 25, 2025 — Q4 2024 Earnings Call and Data Blanket Claims
Management promoted a "significant purchase order" with Data Blanket for drone batteries at 63% gross margins. The complaint recounts that Data Blanket is a small startup with only a handful of employees and no import records showing receipt of SES products. SES mentioned this deal in SEC filings only once, immediately before launching a $150 million ATM offering.
September 18, 2025 — UZ Energy Acquisition Closes
SES announced the $25.5 million acquisition of Shenzhen UZ Energy, describing it as positioning the Company in the "global $300 billion ESS market." As detailed in the action, UZ Energy had minimal U.S. presence and its related entity's registered agent had settled a case alleging participation in a billion-dollar Ponzi scheme.
October 14, 2025 — Hisun Joint Venture Term Sheet
The Company announced a 90%-owned joint venture with Hisun New Energy Materials to commercially supply electrolytes discovered by its Molecular Universe platform. The lawsuit chronicles that Hisun's planned Texas manufacturing facility remained undeveloped swampland, its corporate address was a residential home, and it appeared to have only one U.S. employee.
November 17, 2025 and January 22, 2026 — Insider Sales
The Company's Chief Science Officer sold 250,000 shares on each date, collecting $497,500 and $590,000 respectively, totaling over $1 million in proceeds before corrective disclosures.
December 9, 2025 — Wolfpack Research Report
A short-seller report alleged SES had announced "phantom deals," promoted an AI product that was a "ChatGPT wrapper," and engaged in circular transactions to fabricate revenue. The report included site visit photographs of AISPEX's ramshackle headquarters and Hisun's undeveloped swampland.
March 4, 2026 — The Q4 2025 Earnings Revelation
After market close, SES disclosed that logistics constraints had pushed $1.5 million of revenue into 2026 and issued 2026 guidance of $30 million to $35 million, falling approximately 32% to 42% below the $51.67 million analyst consensus. Shares collapsed 36.8% the following morning.
