## Overview

Sigma Lithium Corp is a U.S.-listed lithium mining company centered on the Grota do Cirilo operation in Minas Gerais, Brazil. It produces lithium oxide concentrate for industrial and battery-material customers and integrates mining with downstream processing at its Greentech Industrial Plant.

## Products & services

• Lithium oxide concentrate production
• Mining and ore beneficiation
• Greentech industrial processing
• Sustainable lithium materials supply
• Mine development and operations in Brazil

- **Lithium oxide concentrate** (85%) — Industrial-grade lithium concentrate produced at the Grota do Cirilo complex for battery supply chains.
- **Mining and beneficiation services** (10%) — Extraction, ore handling, and processing activities that prepare ore for concentrate production.
- **Sustainability-led processing** (5%) — Water reuse, zero toxic chemicals, zero tailings, and renewable-power operations embedded in the plant design.

- Lithium oxide concentrate production
- Mining and ore beneficiation
- Greentech industrial processing
- Sustainable lithium materials supply
- Mine development and operations in Brazil

## Customers

Sigma Lithium sells into the battery materials and industrial minerals supply chain, where buyers need high-purity lithium feedstock for downstream conversion. Its customer base is primarily global producers and processors that use lithium oxide concentrate as an input to battery chemicals and related industrial applications.

- **Battery materials producers** (primary) — Buy lithium oxide concentrate for conversion into battery chemicals and cathode supply chains.
- **Lithium chemical processors** (primary) — Purchase concentrate as a feedstock for downstream chemical refining and industrial processing.
- **Industrial minerals customers** (secondary) — Use lithium-bearing materials in industrial applications where secure supply is important.
- **Global trading counterparties** (secondary) — Trade or off-take lithium materials tied to international demand and logistics.

- Battery-material producers buying lithium feedstock
- Chemical processors converting concentrate into lithium products
- Industrial minerals buyers needing stable supply
- International counterparties seeking Brazil-origin lithium
- Institutional investors indirectly exposed through listed shares

## Geography

The company's operating footprint is centered in Brazil, where Grota do Cirilo and the Greentech Industrial Plant are located in Minas Gerais. Capital markets presence spans the United States, Canada, Brazil, and Australia, reflecting a multinational shareholder and listing base rather than a multi-country mining network.

- Brazil is the core operating base for mining and processing
- Minas Gerais hosts the Grota do Cirilo complex
- United States is a key capital markets location
- Canada and Brazil support existing listings and investor access
- Australia broadens exposure to Asia-Pacific mining investors

## Strategy

Sigma Lithium’s strategy is built around industrial-scale lithium production from a Brazil-based asset with integrated processing and sustainability features. The company also uses international capital markets to broaden ownership and support its growth profile, while maintaining a supply position tied to battery materials demand.

- **Expand and stabilize lithium production** (medium-term) — Higher and more consistent output supports supplier relevance in battery materials markets.
- **Preserve sustainability-led operating model** (long-term) — Water reuse, renewable power, and low-waste processing help differentiate the product and support permitting and community acceptance.
- **Broaden global capital markets access** (short-term) — Multiple listings increase visibility and improve access to institutional investors in lithium markets.

- Scale production from the Grota do Cirilo complex
- Keep processing integrated with mining operations
- Market sustainability as a supply-chain differentiator
- Broaden investor access across global exchanges
- Support long-term lithium supply security

## Risks

The company is exposed to lithium price volatility, operating concentration in a single Brazilian asset, and permitting/community relations that can affect mine continuity. As a mining company, it also faces execution risk in production scaling, country-level political and regulatory risk, and financial reporting complexity from estimates and internal control matters.

- **Lithium price volatility** [high] — Revenue and cash generation depend on a commodity with cyclical pricing and changing market balances.
- **Single-asset operating concentration** [high] — Operations are centered on the Grota do Cirilo complex, so any disruption has outsized impact.
- **Permitting and community relations** [high] — Mining and industrial processing require local approvals and social license to operate.
- **Political and regulatory risk in Brazil** [medium] — A changing regulatory or political environment can affect mining operations and export logistics.
- **Internal control and reporting risk** [medium] — The company disclosed material weaknesses and remediation efforts, which can affect financial reporting reliability.

- Lithium prices can swing sharply and affect revenue visibility
- Single-asset concentration increases operational dependence on Brazil
- Permitting and community support are critical for continuity
- Political and regulatory risk exists in the operating jurisdiction
- Internal control weaknesses and estimates can affect reporting quality

## Accounting

As a mining company, Sigma Lithium’s reported results depend on estimates for reserves, mine lives, depreciation, and asset carrying values. The company also highlighted material weaknesses in internal control over financial reporting, making controls, judgments, and remediation progress especially important for investors.

- **Reserve and mine-life estimates** — Can materially change operating profit and asset carrying values
- **Impairment testing** — Can trigger non-cash write-downs
- **Internal control over financial reporting** — Raises scrutiny over controls, estimates, and disclosures
- **IFRS financial instruments** — May change presentation and note detail for financial assets and liabilities

- Mine-life and reserve estimates affect depreciation and asset values
- Impairment testing matters for large mining and processing assets
- Internal control remediation can affect reporting reliability
- IFRS judgments may affect valuation and classification of financial assets
- Mining costs and production timing can create quarter-to-quarter volatility
