unauthorized access technical

"identified unauthorized access to certain Company systems"

Entry into computer systems, networks, facilities, or data by people who do not have permission to be there—whether by hacking, stolen credentials, bypassing locks, or improper insider activity. For investors, unauthorized access matters because it can lead to stolen customer or financial data, operational shutdowns, regulatory fines, and damage to reputation—like someone breaking into a locked file cabinet and taking sensitive documents, which can reduce a company’s value and increase costs.

exfiltrated technical

"investigation has found that certain files were exfiltrated from the affected systems"

cybersecurity incidents technical

"scope, nature, and impacts of the cybersecurity incidents described herein"

Cybersecurity incidents are events where unauthorized parties disrupt, access, alter, steal, or lock an organization's digital systems, networks, or data — examples include hacking, ransomware attacks, data breaches, and denial-of-service outages. They matter to investors because, like a physical break-in for a storefront, such incidents can interrupt business operations, trigger remediation costs, regulatory fines, legal claims, and reputational harm, all of which can affect revenue, expenses, and public market valuations.

forward-looking statements regulatory

"contains forward-looking statements regarding future events that are subject to the safe harbor"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements regarding future events that are subject to the safe harbor created under the Private Securities Litigation Reform Act of 1995 and other safe harbors under the Securities Act of 1933 and the Securities Exchange Act of 1934. All statements other than statements of historical fact are statements that could be deemed forward-looking statements. These statements are based on current information, beliefs, assumptions and expectations about the matters reported herein. Words such as “expects,” “anticipates,” “projects,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “continues,” “potential,” “may,” “could” and “will,” and variations of such words and similar expressions are intended to identify such forward-looking statements, however, the absence of the foregoing words or expressions does not mean that a statement is not forward-looking. Our actual findings could differ materially from those anticipated in these forward-looking statements as a result of various factors. Forward-looking statements may include, among other things, statements relating to the scope, nature, and impacts of the cybersecurity incidents described herein, the Company’s response thereto and other future events.

The following important factors and uncertainties, among others, could cause actual results to differ materially from those described in the forward-looking statements: the results of the Company’s ongoing investigation and analysis of the scope and details of the cybersecurity incidents and the potential discovery of new and additional information related thereto; the Company’s expectations regarding its ability to contain and remediate the cybersecurity incidents, including the success of containment and remediation activities to date; any unauthorized release of the Company’s data, including third-party data held by the Company, or the use of any such data for fraudulent purposes; potential loss or destruction of Company data or adverse impacts to the Company’s operations; the impact of the cybersecurity incidents on the Company’s relationships with customers, employees, governmental regulators, and other stakeholders; diversion of management’s attention from the Company’s operations to addressing the cybersecurity incidents; the legal, reputational, and financial risks resulting from the cybersecurity incidents, including those that may arise from any potential regulatory inquiries and/or litigation to which the Company may become subject in connection with the incidents; other reputational risk related to the cybersecurity incidents; regulatory scrutiny of the cybersecurity incidents; risks related to the availability of the Company’s insurance coverage for losses and costs associated with the cybersecurity incidents; and remediation and other additional costs that may be incurred by the Company in connection with the investigation and remediation of the incidents. Readers are cautioned that these forward-looking statements are not guarantees of future events or outcomes and they should not be unduly relied on, as they are based on information available to the Company and on management’s current beliefs and expectations as of the date of this Current Report on Form 8-K and are therefore inherently uncertain and subject to risks, uncertainties, and assumptions that are difficult to predict, including those identified in our filings with the Securities and Exchange Commission, including the risk factors contained in our most recent Annual Report on Form 10-K. We undertake no obligation to revise or update any forward-looking statements, including to reflect events or circumstances occurring after the date of the filing of this report, except to the extent required by law.
