Signify Health (SGFY) 8-K Entry into a Material Definitive Agreement

Exhibit 99.6

Subject: Signify-CVS Health Announcement

Signifiers,

I hope you’ve had the chance to read Kyle’s “Exciting Company News” email. This is a tremendous opportunity for all of us at Signify Health, and I hope you are as excited as I am.

Joining CVS Health will open significant new opportunities for our Home & Community Services business, and specifically for our MECs.

CVS Health sees our home health platform as the foundation for future expansion of the company’s home health care delivery. Together, we will be able to design new care models that will combine CVS Health’s resources with Signify’s capabilities, analytics and technology to deliver on our promise to expand our health service offerings and to help patients navigate to the best site of care. The work you do to engage members and support our network providers is essential to our ability to realize this tremendous opportunity.

I want to reassure you that Signify Health will operate as a distinct, payor-agnostic business within CVS Health, led by members of Signify Health’s current management team. So, for us, it is business as usual, and we should remain focused on our work and delivering an excellent experience to our members, just as you do everyday.

We anticipate widespread media coverage of this announcement and some of the members you talk with every day may ask you about it. If you are asked about the news, please let them know how excited Signify Health is to become part of CVS Health and that we believe this will allow us to have a bigger impact on healthcare in the future. Please also affirm that nothing is changing related to their In-Home Evaluation and that we will continue to be able to serve them. To ensure consistent messaging to our members, you will be receiving an updated script Tuesday morning with these points.

You are at Signify at an exciting time, and I couldn’t be prouder of you and everything our HCS team has achieved. As part of CVS Health, we will be able to make a difference in even more patients’ lives. Thank you for all you have done to get us to this point, and for all that I know you will do as we move ahead.
