STANDARD LITHIUM ESTABLISHES AT-THE-
MARKET EQUITY OFFERING PROGRAM UNDER
BASE SHELF PROSPECTUS
VANCOUVER, BC, August 10, 2026 – Standard Lithium Ltd. (“Standard Lithium ” or the
“Company”) (TSXV: SLI) (NYSE American: SLI), a leading near-commercial lithium development
company, today announced the establishment of an “at-the-market” equity program (the “ATM
Program”) under its base shelf prospectus dated July 30, 2025, 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”).
The Company previously registered the offer and sale of up to US$50,000,000 of its common
shares (the “Current Offered Shares ”) under a prior prospectus supplement dated August 8,
2025 (the “Current Prospectus Supplement”) to the Company’s Base Prospectus (as defined
below) filed in Canada, and in the United States, under a prior prospectus supplement dated
August 8, 2025 to the Company’s Registration Statement (as defined below) (the “Current ATM
Program”), in accordance with the terms of an “at-the-market” sales agreement dated August 8,
2025 (the “2025 Sales Agreement”) among the Company and Canaccord Genuity and Evercore
ISI (the “Agents”). As of August 7, 2026, the Company has offered and sold 8,978,213 Current
Offered Shares for aggregate offering proceeds of US$36,012,156, resulting in US$13,987,844
of Current Offered Shares available for issuance under the Current ATM Program. The Company
intends to continue to utilize the Current ATM Program until the earlier of (i) all shares subject to
the Current Prospectus Supplement having been sold in accordance with the terms thereof, and
(ii) the termination of the 2025 Sales Agreement in accordance with its terms, following which the
Company will offer and sell the Offered Shares pursuant to this 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”) among the Company
and 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 in
accordance with the terms of the Sales Agreement.
The Company expects to use the net proceeds of the Offering to fund ongoing work programs to
advance the South West Arkansas Project towards a Final Investment Decision (“FID”) and
construction, for exploration, leasehold acquisition, and development activities in East Texas,
including specifically at the Franklin Project, for working capital and for general corporate
purposes.
Listing of the Offered Shares sold pursuant to the ATM Program on the TSXV 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 August 10, 2026 (the “Prospectus Supplement”) to the Company’s short form
base shelf prospectus dated July 30, 2025 (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 August 10, 2026 (the “U.S. Prospectus Supplement”) to the
