Chart Industries (NYSE: GTLS) sets terms for Series B preferred stock conversion

Rhea-AI Filing Summary

Chart Industries, Inc. will complete the previously disclosed mandatory conversion of its 6.75% Series B Mandatory Convertible Preferred Stock on December 15, 2025, the mandatory conversion date. Under the certificate of designations, each preferred share outstanding on that date will automatically convert into 7.0520 shares of common stock, based on the average trading price of the common shares over the 20 trading days ending on December 11, 2025. Each NYSE-traded depositary share (GTLS.PRB), which represents a 1/20th interest in a preferred share, will therefore convert into 0.3526 shares of common stock.

The conversion will occur automatically, without any action required from holders, and investors of record at the close of business on the conversion date will receive the related common shares. No fractional common shares will be issued; any fractional amounts will be paid out in cash as provided in the governing terms. Trading in the depositary shares on the New York Stock Exchange is expected to be suspended before the market opens on the conversion date, and the depositary shares are expected to be delisted afterward.

Insights

Capital structure and equity securities analyst

Chart is converting its Series B preferred into common stock and delisting the related depositary shares.

Chart Industries confirms the mechanics of the mandatory conversion of its 6.75% Series B Mandatory Convertible Preferred Stock. On December 15, 2025, each preferred share will convert into 7.0520 shares of common stock, with each GTLS.PRB depositary share, representing 1/20th of a preferred share, converting into 0.3526 common shares. The conversion rate is based on the arithmetic average of the daily volume-weighted average price of the common stock over the 20 trading days ending on December 11, 2025, as specified in the certificate of designations.

This event simplifies the company’s equity stack by eliminating the preferred layer tied to GTLS.PRB and replacing it with common equity, while settling any fractional common shares in cash. Trading in the depositary shares is expected to be suspended before the conversion date and the depositary shares are expected to be delisted from the NYSE thereafter. The overall impact on investors depends on the number of preferred and depositary shares held and how the added common shares are valued relative to existing holdings.

Item 8.01 Other Events

As previously disclosed, on December 15, 2025 (the “Mandatory Conversion Date”), each outstanding depositary share (NYSE: GTLS.PRB) (each, a “Depositary Share”) of Chart Industries, Inc. (the “Company”), representing a 1/20th interest in a share of the Company’s 6.75% Series B Mandatory Convertible Preferred Stock (the “Mandatory Convertible Preferred Stock”), will automatically convert into shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”).

Under the applicable certificate of designations (the “Certificate of Designations”), unless earlier converted in accordance with its terms, each outstanding share of Mandatory Convertible Preferred Stock will automatically convert on the Mandatory Conversion Date into a number of shares of Common Stock at the “Mandatory Conversion Rate”, which is based on the arithmetic average of the daily volume-weighted average price of the Common Stock over the 20 consecutive trading day period ending on, and including, December 11, 2025 (the “Final Averaging Period”). Following completion of the Final Averaging Period, the Company determined, in accordance with the Certificate of Designations, that each share of Mandatory Convertible Preferred Stock outstanding on the Mandatory Conversion Date will automatically convert into 7.0520 shares of Common Stock (and, correspondingly, each Depositary Share outstanding on the Mandatory Conversion Date will automatically convert into 0.3526 shares of Common Stock).

The automatic conversion of the Depositary Shares on the Mandatory Conversion Date will occur without any action on the part of holders of Depositary Shares. Holders of Depositary Shares as of the close of business on the Mandatory Conversion Date will be entitled to receive the shares of Common Stock issuable upon conversion of such Depositary Shares.

No fractional shares of Common Stock will be issued in connection with the conversion. Any resulting fractional share will be settled in cash in an amount determined in accordance with the Certificate of Designations.

Trading in the Depositary Shares on the New York Stock Exchange (“NYSE”) is expected to be suspended prior to the opening of trading on the Mandatory Conversion Date, and the Depositary Shares are expected to subsequently be delisted.
