Welcome to our dedicated page for Atlas Corporation SEC filings (Ticker: ATCO), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
The SEC filings page for Atlas Corp. (ATCO) provides access to the company’s regulatory disclosures as a foreign private issuer and former New York Stock Exchange registrant. Atlas has filed reports under the Securities Exchange Act of 1934, including Form 6-K current reports, Form 25 notifications of removal from listing and Form 15 certifications of termination of registration and suspension of reporting obligations.
For investors analyzing capital structure and security status, several filings are particularly relevant. A Form 25 submitted by the New York Stock Exchange identifies Atlas Corp. as issuer and relates to the removal from listing and/or registration of its 7.875% Cumulative Redeemable Perpetual Preferred Shares – Series H. This filing documents the delisting of that preferred series from the exchange.
Subsequent Form 6-K reports describe preferred share redemptions. One Form 6-K details the completion of the redemption of all issued and outstanding Series H preferred shares at a fixed redemption price per share, with regular dividends accrued up to but not including the redemption date paid separately in cash. These filings help holders of preferred shares understand the terms and timing of redemptions.
Atlas’s Form 15 (15-12G) filing is another key document. In it, the company certifies the termination of registration of its common shares, Series D preferred shares, Series H preferred shares and 7.125% senior notes due 2027 under Section 12(g) of the Exchange Act, and suspends its duty to file reports under Sections 13 and 15(d). The filing notes that there was one holder of record as of the certification date, signaling a change in Atlas’s public reporting status.
Earlier, a press release tied to the acquisition of Atlas by Poseidon Acquisition Corp. explains that, upon consummation of the merger, Atlas requested the suspension of trading of its common shares on the NYSE, described as a delisting. While this information appears in a press release rather than a specific SEC form in the provided data, it complements the formal filings by outlining the transaction that preceded the Form 15 and delisting actions.
On this filings page, users can review Atlas’s Form 6-K reports for detailed descriptions of preferred share redemptions, examine the Form 25 for information on the delisting of Series H preferred shares, and consult the Form 15 to understand the termination of registration and suspension of reporting obligations. AI-powered tools on the platform can help summarize these documents, highlight the sections dealing with security status, redemption terms and reporting changes, and clarify the implications for holders of Atlas’s common shares, preferred shares and notes.
