Item 8.01. Other Events.

On September 6, 2013, Chesapeake Lodging Trust (the “Trust”) and Chesapeake Lodging, L.P. (the “Operating Partnership”) entered into separate On Demand Sales Agreements (the “Sales Agreements”) with each of Robert W. Baird & Co. Incorporated and JMP Securities LLC (each, an “Agent” and together, the “Agents”), to permit the Trust to issue and sell up to $100.0 million in the aggregate of its common shares of beneficial ownership (the “Shares”) through a continuous at-the-market offering or other methods (the “ATM program”). Through the date of this Current Report, sales of Shares under the ATM program have totaled approximately $24.0 million.

In accordance with SEC rules promulgated under the Securities Act of 1933, as amended (the “Act”), the Trust’s registration statement on Form S-3 (File No. 333-183280) under which the Shares were originally registered for sale under the Act will expire in September 2015. Although the Trust has no present plans to sell Shares pursuant to the ATM program, on September 4, 2015, the Trust, the Operating Partnership and each Agent amended the respective Sales Agreements (each an “Amendment” and collectively, the “Amendments”) to preserve the Trust’s ability to sell the remaining approximately $76.0 million of Shares available to be sold under the ATM program pursuant to the Trust’s automatic shelf registration statement on Form S-3 (File No. 333-198558) (the “2014 Registration Statement”) rather than pursuant to the Trust’s expiring registration statement on Form S-3. A prospectus supplement is also being filed today to permit the continuation of the ATM program pursuant to the 2014 Registration Statement. No additional Shares are being registered for sale pursuant to the ATM program, nor are any changes to its terms being implemented at this time.

This Current Report shall not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

The Amendments are filed as Exhibits 1.3 and 1.4 to this Current Report. The description of the Amendments does not purport to be complete and is qualified in its entirety by reference to the Amendments filed as exhibits hereto and incorporated by reference herein.

Item 9.01. Financial Statements and Exhibits.
