Exhibit 99.2

Subject: Postponement of Record Date and Stockholder Meeting Date for Sale of OEM Business

Dear Colleagues,

The transaction for the sale of the OEM business is still targeted to close in the second quarter of 2020, subject to meeting all customary closing conditions and receiving approval from RTI’s shareholders. Today, we announced our decision to postpone the record date and stockholder meeting date for this transaction; the new dates will be determined soon. In the meantime, we continue to make progress on ensuring both the Spine and OEM businesses are well-positioned for continuity, autonomy and future growth.

We expect to have more information to share in March on key topics such as org charts for both companies, confirmation and clarity on employee benefit programs and a new company name for Spine.

Thank you again for all you have done over to get us to this point in RTI’s transformation. We have much to look forward to as we progress throughout the year.

Sincerely,

Camille
