Constellation Brands Falls on Guidance, SpaceX Debt Plan Weighs on Premarket
Constellation Brands shares fell 4.9% in premarket trading after the company's fiscal second-quarter 2027 results beat on earnings and revenue but its full-year profit outlook came in below analyst expectations. The company reported adjusted earnings of $3.74 per share, above consensus estimates of roughly $3.55 to $3.61, while net sales rose 6% year over year to $2.63 billion, topping the $2.54 billion estimate, but its reaffirmed fiscal 2027 adjusted EPS guidance of $11.20 to $11.90 carried a midpoint of $11.55, below the analyst consensus of about $11.72. Beer volumes remained weak, with Modelo Especial depletions down roughly 2% and Corona Extra down about 5%, bringing total beer depletions down 0.6% for the quarter, and the company also announced the acquisition of SpikedAde, a vodka-based, zero-sugar ready-to-drink beverage brand, for $75 million upfront plus up to $278 million in contingent payments over five years. Elsewhere in premarket trading, Intel shares rose 1% to around $113.50 after Elon Musk said TSMC will not own or operate the planned Terafab AI chip complex in Texas, easing concerns Intel could lose its role in the project, while Sigma Lithium shares surged nearly 5.9% after a Brazilian Federal Court of Appeals granted emergency suspensive relief upholding its environmental licenses at the Grota do Cirilo complex in Minas Gerais. Space Exploration Technologies shares slid 1.9% after a report said the company is seeking to raise $40 billion in debt to fund a massive Nvidia AI chip order, consisting of roughly $10 billion in bank loans and $30 billion in investment-grade bonds, with Apollo Global Management expected to lead the deal and Pimco among the lenders in early discussions.

Sigma Lithium shares rise after court upholds environmental licenses
A Federal Court of Appeals upheld Sigma Lithium Corporation's environmental licenses, allowing the company to resume mining-industrial operations. The decision overturned a September 8 emergency ruling by a local federal judge in Teofilo Otoni that had suspended those licenses, with Senior Federal Judge Mônica Sifuentes granting Sigma Lithium an emergency motion for suspensive relief on the grounds that a prolonged stoppage would cause significant negative economic impact in the Vale do Jequitinhonha region. Sigma Lithium reaffirmed guidance to scale annualized production of lithium oxide concentrate to 330,000 tonnes by year-end 2027, saying it needs no additional capacity beyond its existing Mine 1 capacity in the South Pit operations and its Cleantech Industrial Plant. The court noted the company supports approximately 19,000 direct and indirect jobs and around 80,000 family members across 12 municipalities. The original suspension stemmed from a lawsuit filed by Ngolo, an association acting for local Quilombola communities, though the government official registry showed no Quilombola heritage descendant houses within a 12 km radius of the Grota do Cirilo Project when its current licenses were issued and operations began in 2023.
Brazilian Congresswoman Welcomes Suspension of Sigma Lithium's Environmental Permits
Federal Deputy Célia Xakriabá publicly welcomed the Minas Gerais state government's decision on Thursday, the 24th, to suspend five environmental operating licenses held by Sigma Lithium. The permits were suspended by the State Environmental Foundation, known as Feam, in compliance with a Federal Court injunction issued on September 4th that nullified the environmental licenses and mandated a total halt to all extraction and pit activities at the Grota do Cirilo project. The suspension follows a formal criminal complaint filed last week by Deputy Xakriabá and fellow Federal Deputy Duda Salabert with the Federal Public Prosecutor's Office and the Federal Police, demanding urgent intervention over evidence that Sigma unlawfully maintained mining operations in defiance of the federal injunction. The congresswoman also criticized Sigma's prominent presence at New York Climate Week, where a company executive is scheduled to ring the Nasdaq closing bell, calling it a severe contradiction for a mining company to present itself as a pillar of the sustainable economy while local communities report human rights violations and defiance of judicial orders. The Baú and Piauí Poço Dantas Quilombola communities in the municipalities of Araçuaí and Itinga, within the Jequitinhonha Valley, continue to report severe environmental degradation and mobility restrictions caused by the Grota do Cirilo operational footprint, and Sigma is alleged to have breached a separate injunction tied to a Conduct Adjustment Agreement requiring vital road access for local families.

Brazilian Judge Suspends Sigma Lithium's Grota do Cirilo Licenses
A Brazilian federal judge ordered the immediate suspension of all environmental licenses held by Sigma Mineração S.A., the operating subsidiary of Sigma Lithium Corporation, for the Grota do Cirilo project, halting mining activities under a September 4 preliminary order following a civil action by the Federation of Quilombola Communities of Minas Gerais. The dispute centers on whether the project lies within the area of influence of the Baú Quilombola Community and therefore required free, prior and informed consultation, with the judge citing studies placing the community's territory approximately 2.7 kilometers from the project's directly affected area, within the 8-kilometer presumptive regulatory impact radius under Interministerial Ordinance No. 60/2015. The court ordered independent georeferencing and barred Minas Gerais and its environmental agency from issuing new licenses, amendments or corrective approvals until community-protection requirements are completed. The suspension is material because Grota do Cirilo is Sigma Lithium's only productive asset, with annualized nameplate capacity of approximately 330,000 metric tons of lithium oxide concentrate, and the company is targeting 240,000 metric tons over 12 months and 330,000 metric tons in fiscal 2027. Local reporting said the court-appointed expert would have 45 days to submit the mapping, and the order follows a July operational pause that ended only after an August state agreement with Minas Gerais.

Sigma Lithium Reports Record Q2 Revenue and Margins
Sigma Lithium reported record second-quarter 2026 results, with net sales revenue of $54.7 million, up 223.9% year over year, and an adjusted EBITDA margin of 47.0%, the highest in company history. Lithium oxide concentrate production reached 35,400 tonnes, a 52% increase from the first quarter, driven by the ramp-up of mining operations. The company realized a net lithium price of $2,089 per ton for SC5, a 17% sequential increase, while plant gate cost fell 36% to $401 per ton and CIF cost decreased 33% to $452 per ton. Sigma Lithium also reduced total debt by 25% over the last year and held $16.7 million in cash as of June 30, 2026, with management projecting an additional $60 million in cash inflows during the third quarter. The company maintained its Plant 1 twelve-month forward guidance of 240,000 tonnes, with the ramp-up timeline pushed forward by three months due to a temporary suspension, and raised its fiscal 2027 production guidance to 330,000 tonnes for Plant 1, exceeding nominal capacity due to improvements in the reprocessing circuit.
Sigma Lithium Corporation shares rose 2.85% to close at $10.48, outperforming the S&P 500's 0.89% gain. The stock has fallen 23.38% over the past month, underperforming the Basic Materials sector's 8.24% decline and the S&P 500's 0.63% loss. Analysts expect the company to report earnings of 15 cents per share on revenue of $54 million in its upcoming release, representing year-over-year growth of 188.24% and 219.72% respectively. Full-year consensus estimates stand at $1.15 per share on revenue of $342 million, marking increases of 355.56% and 210.88% from the prior year. Sigma Lithium carries a Zacks Rank of 3, or Hold, and trades at a forward price-to-earnings ratio of 8.86, a discount to the industry average of 15.4.
Sigma Lithium is generating enough cash to fully repay a $100 million debt facility by year-end, Co-Chair Marcelo Paiva said Friday in a Bloomberg interview. The loan, which accounts for the bulk of Sigma's $134 million in debt as of March 31, matures around December, four years after it was signed with the Brazilian miner's United Arab Emirates-based shareholder Synergy Capital. Paiva told Bloomberg that the company is producing and generating cash, and that the loan carries a high borrowing cost so there is no interest in renewing. Sigma's Grota do Cirilo complex is one of the world's largest hard-rock lithium deposits, and second-quarter production exceeded guidance by 6 percent despite an equipment upgrade. The company reported negative free cash flow in the first quarter but has since benefited from advance payments under lithium concentrate sales agreements, with cash reaching $28 million as of May 15, its highest level since the end of 2024.
Sigma Lithium exceeded its second-quarter production guidance by 6%, delivering 35,000 metric tons of high-grade lithium concentrate compared to its previous expectation of 33,000 tons. The company attributed the performance to the successful execution of a comprehensive mining upgrade following a primarization of its mining operations, while its Cleantech industrial plant achieved 70% recovery of lithium from spodumene ore and a roughly 20% yield. Sigma Lithium also reached a full operating run rate during the quarter from its expanded mining fleet, supported by an optimized mine plan and enhanced operational execution. The company stated that its mining operations team demonstrated readiness to supply raw materials for a second Cleantech industrial plant within 12 months and potentially a third.

Sigma Lithium Corporation announced that a Court of Appeal Judge in the Court of Justice of Minas Gerais overturned a previous lower court ruling that included a potential $10 million legal collateral requirement. The court requested that the company support the appointment of an independent technical advisory firm to assess and monitor the impact of its operations on residents in the municipalities of Aracuai and Itinga. Sigma Lithium welcomed the assessment process, stating that the independent review would provide an opportunity to establish factual information regarding operational impacts. Separately, the company reported filing one year of externally verified environmental monitoring data covering the 12 months through May 2026, which demonstrated compliance with dust, noise, and vibration standards.
