Short T1 Energy – Part 3 of The Whistleblower Series – The Accounting – “Cooking The Books” + Stashing Product at a Secret Warehouse - Fuzzy Panda Research

An internal spreadsheet shows a further $60.5M, roughly one-third of Q1 2026 revenue, also recognized as bill-and-hold.

A whistleblower says T1 Energy booked solar-panel revenue while storing the supposedly sold panels in a newly leased 420,000-square-foot warehouse just a one-minute drive from its Texas factory, because customers did not want them. The warehouse, verified through Texas Department of Licensing and Regulation records, was never disclosed in T1's filings. Behind it sits a broader pattern of late manual journal entries, unsupported bookings, a Protiviti consultant allegedly walking back a fraud warning to KPMG, and mounting internal alarm that expected government cash for 45X tax credits never arrived. Fuzzy Panda Research, which holds a short position, alleges T1's books are not accurate and that the company's reported revenue cannot be trusted.

Thesis

Fuzzy Panda Research alleges that T1 Energy is manipulating its financial statements through unsupported bill-and-hold revenue, late manual journal entries, and compromised internal controls, while concealing inventory and a liquidity problem tied to unrecovered 45X tax credit cash.

• Secret Inventory Warehouse: T1 allegedly leased a previously undisclosed 420,000-square-foot warehouse across the street from its G1 factory in Wilmer, Texas in Q1 2026. Verified through Texas Department of Licensing and Regulation records, the site is a one-minute drive from the factory; Google Street View from April shows semi-trucks making deliveries. No lease disclosure appears in T1's filings. A whistleblower alleges T1 is using the "pleasant run location" to store undelivered bill-and-hold solar panels for which revenue has already been recognized.
• $130M Post-Close Revenue Entry: A January 21, 2026 internal email from former Chief Accounting Officer Denise Cruz allegedly directed the G1 accounting team to book more than $130 million of revenue approximately three weeks after fiscal year-end. T1's 10-K reports $134.4 million of Q4 2025 bill-and-hold revenue from related party Trina Solar. The whistleblower says the initial estimate in Cruz's email was $136.5 million, and that no invoices supported the transaction.
• Unsupported Q1 Bill-and-Hold Continuation: An internal spreadsheet titled "Q1 2026 Revenue Support" shows approximately $60.5 million tied to a "TUS Bill-and-hold" account, which Fuzzy Panda estimates as roughly one-third of total Q1 2026 revenue. T1's Q1 filings did not disclose additional bill-and-hold revenue outstanding. Accounts receivable increased in Q1 when, if prior-period bill-and-hold inventory had shipped to customers, it should have decreased.
• Protiviti Entering Entries Without Support: The whistleblower states T1 routinely used Protiviti, a third-party internal audit consulting firm and Robert Half subsidiary, to input journal entries directly into its books and records, including entries worth hundreds of millions of dollars. Quoted whistleblower statements say T1 management sent Protiviti consultants entries "to move millions of dollars with no support," and that Protiviti consultants had stopped asking for proper backup documentation.
• FY2025 Entries Changed 4.5 Months After Year-End: Internal emails show T1 pushing a Protiviti consultant to rush through 13 journal entries in 30 minutes on April 22, 2026. The report interprets these as changes to "Period 13" FY2025 entries, meaning prior-year financials were allegedly still being altered roughly 4.5 months after fiscal year-end. The whistleblower said such entries would normally be handled by full-time T1 employees such as the plant controller.
• KPMG Audit Fraud Warning Allegedly Walked Back: During T1's FY2025 audit, KPMG circulated a survey asking employees and Protiviti consultants whether they were aware of inappropriate journal entry activity, entries without adequate support, or management override of controls. The whistleblower alleges one Protiviti consultant answered yes and initially told KPMG that fraud was possibly occurring. A Protiviti manager allegedly then intervened and coached the consultant to soften the statement. KPMG passed the FY2025 audit.
• 45X Tax Credit Cash Not Received: The whistleblower says T1 expected government cash for 45X tax credits around April 15, 2026, but the money did not arrive. Internally, management was described as "sweating bullets," and quoted statements say the company did not know where it would get money to meet payroll. Euclid Transactional, the insurer T1 allegedly purchased to cover the 45X credits, was also said by a senior T1 Treasury employee to not be paying out.
• Dissenters Removed and Silenced: Former CAO Denise Cruz and G1 Plant Controller Rusty Williams were both fired in February 2026. The whistleblower says both received severance packages with NDAs, and that other accounting department members also left after raising concerns. T1's 8-K for Cruz's departure did not state that her termination was not due to disagreements with the company. The whistleblower says T1 went through more than 8 to 10 Protiviti consultants in roughly one year, with those who asked questions reassigned or let go.

Catalysts

• Next quarterly filing (Q1 2026 10-Q): Whether T1 discloses the warehouse lease and any additional bill-and-hold revenue will either validate or directly contradict the report's core claims. Absence of disclosure would intensify the case.
• 45X tax credit cash receipt, expected around April 15, 2026 (now overdue per the whistleblower): Any public update on whether the credits have been monetized, or any disclosure of the Euclid Transactional insurance dispute, could move the stock significantly, particularly if liquidity is confirmed to be strained.
• Potential accounting restatement (no date specified): The report argues that unsupported Q4 2025 and Q1 2026 bill-and-hold entries and late FY2025 journal entry changes could require a restatement; any auditor or audit committee action would be a major catalyst.
• Auditor or regulatory action following alleged KPMG survey warning (timing unspecified): If KPMG, the PCAOB, or the SEC opens an inquiry into the journal entry practices or audit process described in the report, that development would significantly escalate the situation.
• Euclid Transactional insurance dispute resolution (timing unspecified): A confirmed refusal by Euclid to pay on T1's 45X tax credit insurance would directly confirm a portion of the liquidity concern and could trigger disclosure obligations.
• Fuzzy Panda's upcoming Part 5 (no date specified): The report references a forthcoming installment alleging proof that U.S. tax credits are flowing to China. Publication would add a new dimension to the case and likely draw regulatory attention.

Company Response

The source report does not indicate that T1 Energy was asked for comment, and no company response is mentioned.

Notable Details

• Internal emails on April 22, 2026 showed T1 pushing a Protiviti consultant to rush through 13 journal entries in 30 minutes. The report interprets these as retroactive changes to FY2025 figures, applied 4.5 months after the fiscal year had closed.
• The whistleblower says T1's accounting system, emails, and invoices were effectively operated in Chinese and built to mirror Trina Solar's own K2 software, with workorders closed by Trina personnel who do not speak English. The whistleblower's words: "Trina built our Oracle to match with their K2."
• A Protiviti consultant who initially told KPMG that fraud was possibly occurring in T1's books allegedly softened that statement after a Protiviti manager intervened. Fuzzy Panda notes that Protiviti is not regulated by the PCAOB or the SEC, unlike an external auditor.
• The whistleblower says T1 churned through more than 8 to 10 Protiviti consultants in roughly one year. Consultants who asked questions were described as either reassigned or fired, and quoted whistleblower language says "the consultants are just wanting to quit left and right."
• T1's insurance provider for its 45X tax credits, Euclid Transactional, is allegedly not paying out on claims. A senior T1 Treasury employee reportedly confirmed to staff that Euclid "has NOT been paying out T1's tax credit insurance."

"Our accounting, if you were to pull our books, are not accurate. I can 100% tell you today they're not accurate."

A whistleblower with direct access to T1's internal records and accounting processes made this statement, which Fuzzy Panda Research cites as the clearest summary of its core allegation.
