Exhibit (a)(5)(C)

Subject: Castlight Health and Vera Whole Health to Combine, Creating Pioneer Company to Scale Value Based Care in Commercial Market.

Hello/Dear [__]

I’m reaching out to share exciting news –

Castlight Health and Vera Whole Health are combining to scale value-based care within the Commercial Market.

This transaction, which is expected to close 1Q2022, has the potential to transform how patients access and engage with care, how providers deliver care, and how employers and other purchasers pay for care. And it dramatically enhances our ability to reduce total cost of care while improving the social, mental, and physical health of our patients.

Vera will continue delivering industry-leading advanced primary care, and will combine Castlight’s industry-leading digital navigation and engagement capabilities.

Can we have a conversation about how our combined company will be able to help you improve health outcomes and reduce your total cost of care? I’d love to speak with you.
