Atlas fully redeems its Series H preferred, ending future dividends on this class.

Atlas Corp. is calling all outstanding 7.875% Series H preferred shares at $25.00 per share, with the redemption effective on October 30, 2025. Holders also receive a final regular cash dividend of $0.492188 per share, covering dividends accrued up to but not including the redemption date. This is a standard par redemption structure for exchange-listed preferred shares.

Once the redemption is completed, the Series H preferred will no longer be outstanding and will cease accruing dividends, removing this security from the company’s capital stack. Income-focused investors in this series receive cash back at par plus the final dividend, while any future preferred income from Atlas would depend on other existing or potential securities, which are not described in this excerpt.
