HIGHLIGHTS 

• Bank of America Research identified 50 companies, amongst all stocks in its coverage universe, which are enablers across scarcity themes in a wide range of sectors that will require transformative solutions including technology, circular economy, and natural capital.
• The report themed "The World Is Not Enough – Scarcity Primer" is accompanied by a recommendation of "50 Stocks For 10 Scarcity Themes". 
• The report identifies the acceleration of technology and sustainability trends as key drivers of increased demand for lithium, identifying the short- and long-term supply risks of the metal from EV battery demand. 
• Sigma Lithium Co-CEO Ana Cabral-Gardner will present at two upcoming conferences starting on the week of February 28, 2022 in the United States: Bank of America Global Agriculture & Materials Conference and BMO Global Metals & Mining Conference. She will be available for "in-person" investor meetings. 

Sigma Lithium Corporation (NASDAQ: SGML) (TSXV: SGML) ("Sigma Lithium" or the "Company"),  dedicated to powering the next generation of electric vehicles with environmentally sustainable and high-purity lithium, was recognized as a top 50 stock in Bank of America Securities Global Research: 50 Stocks for 10 Scarcity Themes.

The report highlights Sigma as one of only a few projects expected to supply additional lithium to the global markets in the near term, therefore 100% exposed to the thematic of the report. Sigma Lithium owns and operates the Grota do Cirilo Project in Brazil and is currently in construction of its "Greentech" commercial production plant. For over 3 years, the Company has been producing lithium concentrate on a demonstration pilot scale at the site. Additionally, it can produce a lithium product with a low environmental footprint as it utilizes hydroelectric power, dry-stacks its tailings, recycles the vast majority of its water, and operates without hazardous chemicals in a flotation circuitry.

Ana Cabral-Gardner, co-CEO of Sigma says: "As a lithium material pure-play, producing battery grade green and sustainable lithium, Sigma Lithium is fully driven by the lithium market and EV growth. As EV demand and battery production expand, the market value of lithium, which was just $27bn in 2020, is set to increase multiple times. However, supply & demand dislocation risk is already impacting lithium prices. Keeping both raw material mining and battery manufacturing capacity in lockstep with demand is challenging given the long lead times to bring new mining capacity online, often taking over 10 years". 

Sigma Speaks at Upcoming Investor Conferences.

On Wednesday, March 2^nd, 2022, at 11:30 a.m. Cabral-Gardner will present at the Bank of America Securities 2022 Global Agriculture and Materials Conference on the lithium market and growing global demand.

Cabral-Gardner will also present at the BMO 31^st Global Metals & Mining Conference on Tuesday, March 1^st, 2022 at 2:45 pm ET on the growing demand for lithium and how projects such as Sigma can play a key role in the energy transition and the future of clean mobility. The live presentation will be available at https://bmo.qumucloud.com/view/2022-gmm-sigma-lithium.

Ana Cabral-Gardner will be available "in-person" for one-on-one meetings throughout the BMO conference from Monday, February 28^th and at the Bank of America conference from Wednesday, March 2^nd. Investors should contact their Bank of America Securities or BMO representatives.
