COMPANY: Sigma Lithium Corporation│NASDAQ: SGMLINDUSTRY: Diversified Metals and Mining We are short Sigma Lithium Corporation (“Sigma” or the “Company”) because Brazilian courtrecords reveal material undisclosed litigation and regulatory enforcement actions by state andfederal prosecutors, millions of dollars of undisclosed creditor lawsuits, and a bombshell technicalreport alleging that safety is so compromised as to risk impairing the future operation andeconomic viability of the mine. PRICE (AS OF CLOSE2/25/2026)USD 16.37MARKET CAPUSD 1.8 BN First,Brazilian litigation records and filingsreveal a bombshell technical report prepared by aBrazilian mining engineering firm in 2025. The technical report alleges that Sigma deviated fromits mine plan and built pit walls so dangerously steep that it created a “high potential for loss of human life,” threatening the safety of workers and the economic viability of the mine. By our read of the analysis, the engineersallege thatSigma sacrificed the mine’s future—and worker safety—to flatter short-term profits. Satellite imagery, reviewed by independent mining experts we retained to corroborate the technical report, found the analysisand allegations credible. We suspect that the alleged safety issues at the mine could explain, in part, the unexpected departure ofthe mining contractor late last year. The mining contractor left the project at the beginning of the rainy season in October 2025,when the technical report alleges worker safety was most at risk. If true, we are skeptical that the mine will fully restart and if itdoes, we think it is highly unlikely that it will continue to operate without interruption, regulatory scrutiny or restriction. Sigma has no margin for error:at last report, it had very little cash, a massive and growing payables balance, and large debtscoming due. Yet undisclosed lawsuits and creditor judgments suggest that Sigma’s liquidity crisis is far worse than investors areled to believe. According to undisclosed Brazilian legal filings and news articles, Sigma’s formermining contractor filed asealed lawsuit against Sigmain São Paulo, and Sigma reportedly owes it R$115 million ($22 million USD). We also discoveredan undisclosed $2 million judgment against Sigma as well as Brazilian legal filings indicating over a dozen additional creditorshave sued Sigma or registered formal debt collection protests against the Company. We also found an undisclosed lawsuit fromDecember 2025,filed by Brazilian state prosecutorsalleging systematicenvironmental and social harm from its mine in Minas Gerais. Remarkably, state prosecutors are seeking not only an injunction,remediation and mining restrictions butprosecutors are asking the court to freeze over $9 million in Sigma’s bank accountbecause they fear that Sigma’s financial condition has so deteriorated that it will not have the money to pay for remediation anddamages.This undisclosed litigation is live, and a ruling from the court on emergency measures is possible any day. Compounding pressure on Sigma,Brazilian federal prosecutorsissued formal “Recomendações” (essentially demand letters)to Brazil’s mining and environmental agencies in September 2025, recommending that the regulatory agenciesreview, suspend,and annul Sigma’s mining authorization. To our knowledge, Sigma has not disclosed any of these highly material lawsuits,prosecutorial or regulatory actions to investors, despite their obvious materiality. Together these undisclosed lawsuits paint a dire picture of a company facing a toxic combination of safety allegations andexistential legal threats from a combination of federal and state prosecutors, creditors and suppliers.Failing to disclose thesematerial liabilities is consistent with a Company that appears to be in disarray: Sigma has had5 CFOs in 3 years, and repeatedindependent director resignations.We struggle to remember any public company that has churned through as many CFOs insuch a short time that did not ultimately collapse. 1.Bombshell Technical Report Alleges Sigma So Deviated From the Mine Plan that it Impaired the Viability ofthe Mine And Created High Potential for Loss of Human Life.A 2025 technical report (the “Chiavini Report”)prepared by a mine engineering firm that examined Grota do Cirilo on behalf of a litigant in a shareholder lawsuitconcluded that Sigma deviated from its approved mine plan in ways that created pit walls so dangerously steep thatthere is a “high potential for loss of human life,”threatening the safety of workers and “considerable economiclosses.”We suspect that steeper walls gave Sigma faster access to the ore body and allowed it to avoid the costs ofstripping more benches. By our read of the Chiavini Report, it is reasonable to conclude thatSigma sacrificed themine’s future—and worker safety—to flatter short-term profits. We purchased satellite images of the mine and asked independent mining experts to review the analysis andconclusions in the techn
