Item 7.01 Regulation FD Disclosure.

In response to questions it has received, LabCorp(R) (NYSE: LH) announced that it has been notified by Retrieval-Masters Creditors Bureau, Inc. d/b/a American Medical Collection Agency (AMCA) about unauthorized activity on AMCA’s web payment page (the AMCA Incident). According to AMCA, this activity occurred between August 1, 2018, and March 30, 2019. AMCA is an external collection agency used by LabCorp and other healthcare companies. LabCorp has referred approximately 7.7 million consumers to AMCA whose data was stored in the affected AMCA system. AMCA’s affected system included information provided by LabCorp. That information could include first and last name, date of birth, address, phone, date of service, provider, and balance information. AMCA’s affected system also included credit card or bank account information that was provided by the consumer to AMCA (for those who sought to pay their balance). LabCorp provided no ordered test, laboratory results, or diagnostic information to AMCA. AMCA has advised LabCorp that Social Security Numbers and insurance identification information are not stored or maintained for LabCorp consumers.

AMCA has informed LabCorp that it is in the process of sending notices to approximately 200,000 LabCorp consumers whose credit card or bank account information may have been accessed. AMCA has not yet provided LabCorp a list of the affected LabCorp consumers or more specific information about them.

AMCA has indicated that it is continuing to investigate this incident and has taken steps to increase the security of its systems, processes, and data. LabCorp takes data security very seriously, including the security of data handled by vendors. AMCA has informed LabCorp that it intends to provide the approximately 200,000 affected LabCorp consumers with more specific information about the AMCA Incident, in addition to offering them identity protection and credit monitoring services for 24 months. LabCorp is working closely with AMCA to obtain more information and to take additional steps as may be appropriate once more is known about the AMCA Incident.

In response to initial notification of the AMCA Incident, LabCorp ceased sending new collection requests to AMCA and stopped AMCA from continuing to work on any pending collection requests involving LabCorp consumers.
