STANDARD LITHIUM ANNOUNCES US$50

MILLION AT-THE-MARKET EQUITY OFFERING

PROGRAM

VANCOUVER, BC, November 17, 2023 – Standard Lithium Ltd. (“Standard Lithium” or the

“Company”) (TSXV: SLI) (NYSE American: SLI), a leading near-commercial lithium company,

today announced the establishment of an “at-the-market” equity program (the “ATM Program”)

that allows the Company to issue and sell, from time to time through agents, up to US$50,000,000

(or the Canadian dollar equivalent) of its common shares (the “Offered Shares”) from treasury to

the public, at the Company’s discretion (the “Offering”).

Sales of Offered Shares, if any, under the ATM Program are anticipated to be made in

transactions that are deemed to be “at-the-market distributions” as defined in National Instrument

44-102 – Shelf Distributions and an “at the market offering” within the meaning of the U.S.

Securities Act of 1933, as amended, including sales made directly on the TSX Venture Exchange

(the “TSXV”), the NYSE American LLC (the “NYSE American”), or any other trading market for

the Offered Shares in Canada or the United States, at the prevailing market price at the time of

sale. The volume and timing of sales under the ATM Program, if any, will be determined in the

Company's sole discretion, and at the market price prevailing at the time of each sale, and, as a

result, sale prices may vary.

Distributions of the Offered Shares through the ATM Program, if any, will be made pursuant to

the terms of an “at-the-market” sales agreement (the “Sales Agreement”) between the Company

and Citigroup and Canaccord Genuity (together, the “Agents”). The ATM Program will be

effective until the issuance and sale of all of the Offered Shares issuable pursuant to the ATM

Program, unless terminated prior to such date by the Company or the Agents in accordance with

the terms of the Sales Agreement.

The Company expects to use the net proceeds of the Offering for advancement of the South West

Arkansas Project, the Lanxess Property Project, the demonstration plant, the expansion in East

Texas, for working capital and for general corporate purposes.

Listing of the Offered Shares sold pursuant to the ATM Program on the TSX Venture Exchange

and/or the NYSE American will be subject to fulfilling all applicable listing requirements.

The sale of Offered Shares through the ATM Program is being made pursuant to a prospectus

supplement dated November 17, 2023 (the “Prospectus Supplement”) to the Company’s short

form base shelf prospectus dated July 26, 2023 (the “Base Prospectus”) filed with the securities

commissions in each of the provinces and territories of Canada, and in the United States pursuant

to a prospectus supplement dated November 17, 2023 (the “U.S. Prospectus Supplement”) to

the Company’s short form base shelf prospectus contained in the Company’s effective registration
