Golden Minerals to Effect 1-for-25 Reverse Stock Split

GOLDEN, Colo.--(BUSINESS WIRE)--May 30, 2023--Golden Minerals Company (“Golden

Minerals,” “Golden” or the “Company”) (NYSE-A: AUMN and TSX: AUMN) announced today

that at its annual meeting of stockholders held on May 26, 2023, its stockholders approved a

reverse stock split of the Company’s common stock. On February 24, 2023, the Company’s

board of directors approved a reverse stock split to be effected at a ratio of between 1-for-2

shares and 1-for-25 shares, with the split ratio to be decided by the board subsequent to

stockholder approval. The board today announced it has selected a reverse stock split ratio of 1-

for-25 shares.

On or around May 30, 2023, the Company will file an amendment to its Amended and Restated

Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware to

effect the reverse stock split. The reverse stock split will become effective on Friday, June 9,

2023, at 12:01 am EDT. Trading of the shares of the Company’s common stock on a split-

adjusted basis will begin simultaneously on the NYSE American and Toronto Stock Exchange

under the new CUSIP 381119403 on June 9, 2023.

When the reverse stock split becomes effective, every 25 shares of the Company’s issued shares

of common stock will be combined into one share of common stock without any action on the

part of the Company or its stockholders. This will reduce the number of issued and outstanding

shares of common stock from approximately 178 million shares to approximately 7.1 million

shares. Proportionate adjustments will also be made to the number of shares issuable upon the

exercise or vesting of all then-outstanding warrants and restricted stock units, which will result in

a proportional decrease in the number of shares of common stock reserved for issuance upon

exercise or vesting of such warrants and restricted stock units.

The reverse stock split will affect all stockholders uniformly and, as of the effective date, each

stockholder will own a reduced number of shares of common stock. Percentage ownership

interests, voting rights and other rights and preferences will not be affected, except to the extent

that the reverse stock split will result in fractional shares. As a result of the reverse stock split,

any stockholder who would otherwise be entitled to a fractional share of common stock will have

their shares rounded up to the next whole number of shares.

The number of shares of common stock reserved for issuance under Golden Minerals’ equity

compensation plans, including the 2023 Equity Incentive Plan approved by stockholders on May

26, 2023, will be reduced proportionately. In addition, the total number of shares of common

stock that the Company is authorized to issue under its Amended and Restated Certificate of

Incorporation, as amended, will be reduced from 350 million to 28 million.

Stockholders who hold their shares through an intermediary such as a bank, broker or other

nominee account should not need to take any action and should see the effect of the reverse stock

split reflected in their accounts on or after June 9, 2023. These beneficial stockholders are

encouraged to follow up with their intermediary with any questions. Stockholders who hold their

shares in book-entry form under the direct registration system with the Company’s transfer

agent, Computershare, will not need to take any action and will see the effect of the reverse stock

split reflected in their accounts on or after June 23, 2023. Stockholders who hold paper

certificates will receive a Letter of Transmittal from Computershare, which when completed and

submitted to Computershare will enable them to exchange their old paper certificates for a book-

entry direct registration account representing the post-reverse stock split number of shares of

common stock they hold. No new paper certificates will be issued.
