Item 1.01Entry into a Material Definitive Agreement.

On September 24, 2026, Century Casinos, Inc. (the “Company”) entered into a Share Purchase Agreement (the “Purchase Agreement”), by and among Century Resorts Management GmbH (“Seller”), a subsidiary of the Company, the Company, Racing Entertainment Centre Holdings Inc. (“Purchaser”), and Highfield Investment Group Inc. (“Highfield”), which is the parent of the Purchaser, pursuant to which the Company agreed to sell the racing and gaming operations of Century Mile Racetrack and Casino in Edmonton, Alberta, Canada (“Century Mile”) and Century Downs Racetrack and Casino in Calgary, Alberta, Canada (“Century Downs” and, together with Century Mile, the “Properties”), for approximately $16.4 million (subject to adjustment based on the Properties' working capital at closing), subject to the conditions and terms set forth therein. The Company owns all of the issued and outstanding shares of Century Mile Inc. and 75% of the issued and outstanding shares of United Horsemen of Alberta Inc. (“Century Downs”); noncontrolling partners of United Horsemen of Alberta Inc. own the remaining 25% of Century Downs.

The real estate underlying the Properties is owned by subsidiaries of VICI Properties Inc. (“VICI”) and is leased to the operating companies under the Company's existing triple-net master lease agreement (the “Master Lease”). In connection with the closing of the transaction, subsidiaries of the Company and VICI will amend the Master Lease to remove the Properties, and Highfield will become the new tenant of the Properties and be responsible for the associated rent obligations going forward. With the removal of the Properties from the Master Lease, the Company's annual rent will be reduced by approximately $7.5 million (based on USD CAD exchange rate of 0.7074 as of September 27, 2026). The Company intends to use the proceeds from the transaction to reduce its indebtedness.

The Purchase Agreement contains customary representations, warranties, covenants and indemnities by the parties to such agreement and is subject to customary closing conditions, including, among other things, (i) the receipt of applicable gaming regulatory approvals, (ii) the accuracy of the respective parties' representations and warranties, subject to customary qualifications, and (iii) material compliance by the parties with their respective covenants and obligations. In addition, the Purchase Agreement contains certain termination rights, including by either party in the event the closing has not occurred within 365 days of the date of the Purchase Agreement, subject to the terms and conditions set forth therein. The transaction is expected to close in the fourth quarter of 2026 or the first quarter of 2027.

The summary of the Purchase Agreement in this Current Report on Form 8-K is qualified by reference to the full text of the Purchase Agreement, which is included as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.

The Purchase Agreement has been attached as an exhibit to this report to provide investors and security holders with information regarding its terms. It is not intended to provide any other information about the Company or its subsidiaries and affiliates. The representations, warranties and covenants contained in the Purchase Agreement were made only for purposes of such agreement and as of specific dates, are solely for the benefit of the parties to the Purchase Agreement, may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Purchase Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the parties that differ from those applicable to investors. Investors should not rely on the representations, warranties or covenants or any description thereof as characterizations of the actual state of facts or condition of the Company or any of its subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Purchase Agreement, which subsequent information may or may not be fully reflected in public disclosures by the Company or its subsidiaries or affiliates.

Item 7.01 Regulation FD Disclosure.

On September 28, 2026, the Company issued a press release announcing the entry into the Purchase Agreement. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

The information in this Item 7.01, including Exhibit 99.1 attached hereto, is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference into any filing

under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.
