---

Boyd Gaming Corporation (the "Company") recently experienced a cybersecurity incident in which an unauthorized third party accessed our internal IT system. The cybersecurity incident has had no impact on the Company's properties or business operations.

Upon detecting the incident, the Company promptly took steps to respond to the incident with the assistance of leading external cybersecurity experts and in cooperation with federal law enforcement authorities.

The Company has determined that the unauthorized third party removed certain data from the Company's IT systems, including information about employees and a limited number of other individuals. The Company is notifying impacted individuals and has or will notify its various regulators and other governmental agencies as required.

As of the date of this filing, the Company believes that the incident will not have a material adverse effect on the Company's financial condition or results of operations. The Company maintains a comprehensive cybersecurity insurance policy, which we expect will cover costs associated with incident response and forensic investigations, as well as business interruptions, legal actions and regulatory fines, if any, subject to policy limits and deductibles.

The information included in Item 7.01 of this Current Report on Form 8-K 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 other filing under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in any such filing.

Such statements contain words such as "may," "will," "might," "expect," "believe," "anticipate," "could," "would," "estimate," "continue," "pursue," or the negative thereof or comparable terminology, and may include (without limitation) information regarding the Company's expectations, goals or intentions regarding future performance. These forward-looking statements are based on the current beliefs and expectations of management and involve risks and uncertainties that could cause actual results to differ materially from those expressed in the forward-looking statements. Many of these risks and uncertainties relate to factors that are beyond Boyd Gaming's ability to control or estimate precisely.

Factors that might cause the Company's actual results to differ materially from those anticipated in forward-looking statements include, but are not limited to: the Company's ongoing assessment of the impacts of the cybersecurity incident, including the Company's potential discovery of additional information related to the incident in connection with its investigation or otherwise; the Company's expectations regarding its ability to contain and remediate the cybersecurity incident; the impact of the cybersecurity incident on the Company's relationships with customers, employees, and governmental regulators; the legal, reputational, and financial risks resulting from the cybersecurity incident, including as may arise from any potential regulatory inquiries and/or litigation to which the Company may become subject in connection with the incident; remediation and other additional costs that may be incurred by the Company in connection with the investigation and remediation of the incident; and the risks discussed under the heading "Risk Factors" and in other sections of the Company's Annual Report on Form 10-K, its Quarterly Reports on Form 10-Q, and in the Company's other current and periodic reports filed from time to time with the SEC. The reader is cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this release.
