  Content	Sigma Lithium Corporation (NASDAQ: SGML, TSXV: SGML) is back on traders' radar this Monday, with the stock ripping higher in premarket trading as investors react to a powerful mix of macro lithium news, fresh institutional buying and the company's latest Q3 2025 results. Sigma Lithium is one of today's standout premarket gainers in the U.S. market. On StockAnalysis' premarket movers list, SGML is up around 35% to $8.20 , with more than 12 million shares changing hands before the opening bell. [1] to , with more than changing hands before the opening bell. RTT News' 'Morning Market Movers' report also flags Sigma Lithium as a notable premarket gainer, showing the stock up 23% at $7.47 as of 7:15 a.m. ET. [2] as of 7:15 a.m. ET. ChartMill's premarket screen shows an even stronger move at one snapshot in time, with SGML indicated up about 39–40%, trading in the mid‑$8 range. [3] These sharp moves come after SGML closed last session at $6.06 (Friday), already up about 2.7% on heavy volume of 8.29 million shares—more than double its recent average of 3.85 million. [4] In other words: the rally started Friday on earnings and institutional headlines, and is accelerating this morning as the broader lithium sector catches a bid. Today's move in SGML is not happening in isolation. Lithium producers globally are climbing after a bullish demand forecast out of China. A syndicated article originally carried by Stocktwits and MENAFN reports that lithium stocks rallied premarket after a major Chinese producer, Ganfeng Lithium Group, sounded an upbeat note on future demand: [5] The most‑active lithium carbonate futures contract on the Guangzhou Futures Exchange jumped about 9% and closed limit‑up around 95,200 yuan (≈$13,400) per tonne . contract on the jumped about around . Ganfeng's chairman Li Liangbin told an industry conference he expects lithium demand to grow roughly 30% in 2026 , and said that if growth reaches 40% , prices could climb toward 150,000–200,000 yuan per tonne. told an industry conference he expects , and said that if growth reaches , prices could climb toward per tonne. Li also warned that supply may struggle to keep up with demand in the short term despite a current surplus of about 200,000 tonnes this year. The same piece notes that Albemarle and Lithium Americas were up modestly in early trading, while Sigma Lithium 'jumped over 17%' as part of the sector-wide rally. [6] McKinsey research cited in the article projects global battery demand climbing from roughly 1,970 GWh in 2025 to about 3,910 GWh by 2030, with AI data centers and stationary storage joining electric vehicles as major consumers—an important backdrop for Sigma's long‑term narrative. [7] Underneath today's fast price action is a very specific corporate story. On November 14, Sigma Lithium released its Q3 2025 results. The company reported: [8] Net revenue: $28.5 million, up 69% quarter‑over‑quarter and 36% year‑over‑year . $28.5 million, up and . Sales volume: 48.6 kt of spodumene concentrate, up 21% vs. Q2 , though still down 15% from Q3 2024. 48.6 kt of spodumene concentrate, up , though still down from Q3 2024. Average net realized price:$586 per tonne, a 40% QoQ and 61% YoY increase as the company leaned on provisional pricing and client partnerships to capture favorable swings in lithium prices. However, profitability remains a challenge: EBITDA: –$6.2 million, an improvement from –$17.1 million in Q2 but still firmly negative. [9] –$6.2 million, an improvement from in Q2 but still firmly negative. Q3 margins were weighed down by lower production, higher cash costs (cash cost + royalties rose to $543/t, +23% QoQ), and the tail end of operational disruptions. A key reason for soft production metrics in Q3: Sigma temporarily shut down mining at its flagship Grota do Cirilo operation in Brazil. According to commodity intelligence group Argus , Sigma phased down mining in late September and fully shut the mine in October 2025 to upgrade equipment and change contractors, resulting in a 36% QoQ and 27% YoY drop in Q3 production to 44,000 tonnes and no exports in October . [10] , Sigma phased down mining in late September and to upgrade equipment and change contractors, resulting in a in Q3 production to and . Operations resumed in early November, with management guiding to a return to normal output within 2–3 weeks and targeting around 73,000 tonnes in Q1 2026, slightly above the comparable period this year. [11] The company frames the shutdown as a necessary reset to align the mine with its upgraded 'Greentech 3.0' industrial plant, which has been delivering recoveries above 70% since early 2025. [12] One of Sigma Lithium's more eye‑catching moves this quarter is its plan to monetize lithium‑rich tailings, which it brands as 'middlings.' From the Q3 release and subsequent coverage: [13] The company plans to sell 950,000 tonnes of dry, solid by‑products containing roughly 1–1.3% lithium to buyers in China. of dry, solid by‑products containing roughly to buyers in China. Sigma has quoted pricing around $120 per tonne , implying roughly $33 million of potential incremental revenue in Q4 2025. , implying roughly of potential incremental revenue in Q4 2025. About 100,000 tonnes are already stocked at the port of Vitória and another 850,000 tonnes sit at the mine, with shipping costs estimated at $40/t and $85/t, respectively. Management argues that monetizing middlings, combined with higher plant recoveries and the mining upgrades, should boost cash generation just as lithium sentiment appears to be stabilizing. Sigma Lithium's balance sheet has been under close watch all year, and Q3 results didn't change that. From the company's own release plus MarketBeat's earnings coverage: [14] Cash and equivalents (Sept. 30, 2025): $6.1 million, plus about $20 million in trade receivables, for $26.1 million in near‑term liquidity. $6.1 million, plus about in trade receivables, for in near‑term liquidity. By mid‑November, Sigma reports converting receivables into $21 million in cash and capturing an additional ~$8 million on settled receivables as prices moved in its favor, bringing available cash to roughly $29 million . [15] in cash and capturing an on settled receivables as prices moved in its favor, bringing available cash to roughly . Short‑term trade finance debt: Reduced to $37 million , down about 38% through 2025, as the company focuses on deleveraging expensive working‑capital lines. [16] Reduced to , down about through 2025, as the company focuses on deleveraging expensive working‑capital lines. Total debt: About $161.9 million, down slightly from Q2. [17] MarketBeat's fundamental snapshot highlights ongoing financial stress: Debt‑to‑equity: ~ 1.26 ~ Quick ratio: 0.39; current ratio: 0.60 0.39; 0.60 Net margin: roughly –35.7%; ROE: about –47%. [18] In short: liquidity has improved versus mid‑year, especially with the middlings sale and receivables conversion, but Sigma remains highly leveraged and not yet profitable. Today's news flow isn't just about lithium futures and premarket screens. There's also a fresh sign of institutional interest. In a new filing‑driven note published November 17, MarketBeat reports that Waratah Capital Advisors Ltd.: [19] Increased its Sigma Lithium position by 93% in Q2 , buying an additional 109,530 shares. , buying an additional 109,530 shares. Now holds 227,330 SGML shares, about 0.20% of the company, valued near $1.02 million at the time of filing. Waratah joins a list of hedge funds and asset managers that have been building or initiating positions in Sigma, including Woodline Partners, Amundi, Aberdeen and Nuveen, among others. Altogether, MarketBeat estimates that institutional and hedge‑fund ownership is roughly 64.9% of the float. [20] Given the stock's volatility and year‑to‑date drawdown, some investors will see this as a vote of confidence that the worst of the operational reset could be behind the company—though the positions are still relatively small compared with Sigma's total market value. If you look at different data providers today, you'll see two very different snapshots of analyst sentiment on Sigma Lithium. A fresh article on Sete News, also dated November 17, summarizes 'Wall Street's leading experts' on SGML: [21] It counts 15 analysts covering the stock: 9 with Buy ratings 5 with Hold ratings 1 with a Sell covering the stock: The 12‑month price target range is $7 to $10, with an average around $8.5, implying about 40% upside from Friday's close (~$6.06) if those targets are met. Sete also notes: Trailing twelve‑month EPS of roughly –$0.31 , with next‑year EPS estimates around +$0.21 and an average EPS forecast of $0.05 for the next quarter . , with and an average EPS forecast of . That implies very rapid earnings growth on paper—though those forecasts clearly assume a successful production ramp and firm lithium prices. By contrast, MarketBeat's coverage of Sigma's Q3 earnings and today's Waratah filing paints a more skeptical picture: [22] It characterizes consensus as a 'Sell' rating, with an average price target around $7 . rating, with an average price target around . Recent moves include: Bank of America cutting the stock from Buy to Neutral and setting a $7 target. Zacks downgrading SGML to a 'Strong Sell.' Weiss Ratings assigning a 'Sell (D‑)' score. Wall Street Zen lowering its view from 'Hold' to 'Sell.' Cormark upgrading to a 'Moderate Buy,' a rare bright spot among the ratings. The takeaway: opinion is sharply divided. Some data sources emphasize the growth story and potential upside to price targets, while others highlight execution risk, balance‑sheet pressure and a difficult year for the stock. Even with today's jump, Sigma Lithium is still digging out of a deep performance hole. Sete News' performance breakdown as of Friday shows: [23] 1‑week: + 13.9% + 1‑month: – 10.6% – 3‑month: – 6.1% – 6‑month: – 7.9% – 1‑year: – 46.0% – Year‑to‑date: –55.4% Key trading stats: Friday high/low: $6.55 / $5.29, on 8.29 million shares. [24] $6.55 / $5.29, on shares. 52‑week range:$4.25 – $14.77, underscoring just how far the stock has fallen from its highs. [25] Today's premarket spike into the high‑$7s / low‑$8s, if sustained, will improve those short‑term performance numbers, but SGML would still be trading at a steep discount to its 52‑week high and well below the levels seen during the peak of lithium enthusiasm. Beyond short‑term trading, Sigma continues to pitch itself as a strategic, ESG‑focused supplier of lithium for the global energy transition. According to company and PRNewswire disclosures: [26] Sigma currently produces about 270,000 tonnes of lithium oxide concentrate per year (≈ 37–40k t LCE ) at its Greentech Industrial Plant in Brazil. (≈ ) at its in Brazil. The company is constructing a second plant that would bring total capacity up to around 520,000 t of concentrate (≈ 77–80k t LCE ) annually once complete. that would bring total capacity up to (≈ ) annually once complete. The Greentech 3.0 upgrade has already delivered recoveries above 70%, but mining operations had to be upgraded to keep pace—hence the Q3 shutdown and restart now underway. Sigma also emphasizes its 'Quintuple Zero' Green Lithium branding—zero coal power, zero tailings dams, zero potable water use, zero hazardous chemicals and zero lost‑time accidents—as a differentiator for automakers and battery makers sensitive to ESG credentials. [27] On October 17, 2025, Sigma Lithium announced that its U.S.‑listed shares were included in the Morgan Stanley National Security Stock Index, a thematic index tracking companies viewed as strategically important to national security and supply‑chain resilience. [28] The index includes a roster of other critical‑materials and energy names—from Albemarle and Freeport‑McMoRan to Cameco, MP Materials and Tesla—highlighting how lithium and broader battery supply chains are increasingly being treated as strategic assets. Putting today's numbers together: Ticker: SGML (NASDAQ, TSXV) SGML (NASDAQ, TSXV) Friday close: $6.06 [29] $6.06 Premarket (various feeds): mid‑ $7s–$8s , up roughly 23–35% at different timestamps.

[35] about shares outstanding and in the public float. Short interest (Oct 31, 2025): roughly 10.6 million shares, indicating a significant bearish bet against the stock. [36] For investors and industry watchers following Sigma Lithium after today's explosive premarket move, a few key storylines stand out: Execution on the mine restart and ramp‑up Can Sigma return production to targeted levels in Q4 and Q1 2026 without further disruptions? [37] Monetization of middlings and cash generation Will the $33 million tailings sale to Chinese buyers close on the expected timeframe and pricing, and how much of that flows straight into strengthening the balance sheet? [38] Lithium price trajectory Ganfeng's forecast and the Guangzhou futures spike suggest sentiment may be turning, but lithium has been a volatile market; sustained price support is crucial for Sigma's margins. [39] Analyst and institutional behavior Does today's move trigger more rating changes, new coverage or further buying (or selling) from institutions beyond Waratah and the current hedge‑fund base? [40] Any update on long‑running strategic review / M&A chatter Sigma has explored strategic alternatives in the past, and market participants continue to speculate about potential interest from automakers or battery giants, especially as the company positions itself as a green, strategic‑materials supplier.
