This notice provides information about a recent incident involving potential unauthorized access to personal information
related to certain current and former patients of United Medical Doctors (“UMD”). Protecting the confidentiality,
privacy, and security of the information entrusted to us is a top priority, and we are acting quickly and diligently to
address this matter.

What Happened? On or about March 31, 2026, UMD detected suspicious activity on its network consistent with a
cybersecurity event. UMD conducted an investigation into this activity and discovered that unauthorized access to its
systems occurred at varying times between December 12, 2025, and March 31, 2026. During this time, the unauthorized
user gained access to and/or acquisition of certain files within UMD’s environment. UMD is now reviewing these files
to understand whether any sensitive information related to individuals may be contained therein.

What information was involved? The information involved in this event is currently unknown.

What are we doing? The confidentiality, privacy, and security of information within our care is among UMD’s highest
priorities. In addition to directly notifying potentially impacted individuals of this event, UMD is notifying appropriate
governmental regulators of this event.

What can you do? We encourage potentially impacted individuals to remain vigilant against incidents of identity theft
and fraud by reviewing your account statements and monitoring your free credit reports for suspicious activity and to
detect errors. Individuals may contact the three major credit reporting agencies for advice on how to obtain free credit
reports and how to place fraud alerts and security freezes on credit files. The relevant contact information is below.

For more information. If you have questions, or need assistance, please call (844) 403-4512, Monday through Friday
from 8:00 a.m. to 4:00 p.m. Central Time. You may also write to UMD at 5601 Executive Dr Suite 250, Irving, TX

Monitor Your Accounts. Under U.S. law, a consumer is entitled to one free credit report annually from each of the three
major credit reporting bureaus, Equifax, Experian, and TransUnion. To order a free credit report, visit
www.annualcreditreport.com or call, toll-free, 1-877-322-8228. Consumers may also directly contact the three major
credit reporting bureaus listed below to request a free copy of their credit report.

Consumers have the right to place an initial or extended “fraud alert” on a credit file at no cost. An initial fraud alert is a
1-year alert that is placed on a consumer’s credit file. Upon seeing a fraud alert display on a consumer’s credit file, a
business is required to take steps to verify the consumer’s identity before extending new credit. If consumers are the
victim of identity theft, they are entitled to an extended fraud alert, which is a fraud alert lasting seven years. Should
consumers wish to place a fraud alert, please contact any of the three major credit reporting bureaus listed below.

As an alternative to a fraud alert, consumers have the right to place a “credit freeze” on a credit report, which will prohibit
a credit bureau from releasing information in the credit report without the consumer’s express authorization. The credit
freeze is designed to prevent credit, loans, and services from being approved in a consumer’s name without consent.
However, consumers should be aware that using a credit freeze to take control over who gets access to the personal and
financial information in their credit report may delay, interfere with, or prohibit the timely approval of any subsequent
request or application they make regarding a new loan, credit, mortgage, or any other account involving the extension of
credit. Pursuant to federal law, consumers cannot be charged to place or lift a credit freeze on their credit report. To
request a credit freeze, individuals may need to provide some or all of the following information:

1. Full name (including middle initial as well as Jr., Sr., II, III, etc.);
2. Social Security number;
3. Date of birth;
4. Addresses for the prior two to five years;
5. Proof of current address, such as a current utility bill or telephone bill;
6. A legible photocopy of a government-issued identification card (state driver’s license or ID card, etc.); and
7. A copy of either the police report, investigative report, or complaint to a law enforcement agency concerning identity theft if they are a victim of identity theft.

Should consumers wish to place a credit freeze or fraud alert, please contact the three major credit reporting bureaus listed below:

Additional Information Consumers may further educate themselves regarding identity theft, fraud alerts, credit freezes, and the steps they can take to protect your personal information by contacting the consumer reporting bureaus, the Federal Trade Commission, or their state Attorney General. The Federal Trade Commission may be reached at: 600 Pennsylvania Avenue NW, Washington, D.C. 20580; www.identitytheft.gov; 1-877-ID-THEFT (1-877-438-4338); and TTY: 1-866- 653-4261. The Federal Trade Commission also encourages those who discover that their information has been misused to file a complaint with them. Consumers can obtain further information on how to file such a complaint by way of the contact information listed above. Consumers have the right to file a police report if they ever experience identity theft or fraud. Please note that in order to file a report with law enforcement for identity theft, consumers will likely need to provide some proof that they have been a victim. Instances of known or suspected identity theft should also be reported to law enforcement and the relevant state Attorney General. This notice has not been delayed by law enforcement.
