Tivity Health Completes Acquisition of Nutrisystem

Combined Offerings Will Meet Growing Demand for Integrated Solutions to Support

Healthier Lifestyles

NASHVILLE, Tenn., March 8, 2019 – Tivity Health^®, Inc. (Nasdaq: TVTY), a leading provider of fitness and health improvement programs, today announced that it has completed its previously announced acquisition of Nutrisystem, Inc., a leading provider of weight management products and services, for approximately $1.3 billion in cash and stock. With this acquisition, Tivity Health will be unique in offering, at scale, an integrated portfolio of fitness, nutrition and social engagement solutions to support overall health and wellness.

PowerfulCalories In + Calories Out Combination

Tivity Health believes this powerfulCalories In+ Calories Outcombination will offer a holistic approach to addressing critical health needs, lowering healthcare costs, and creating additional value for shareholders, health plans, fitness partners, members and consumers. The combined company will have a footprint of more than 75 million members eligible for Tivity Health’s SilverSneakers^®, Prime^® Fitness, WholeHealth Living^™ and flip50^™ programs and millions of consumers for Nutrisystem’s Nutrisystem^®, South Beach Diet^®, and DNA Body Blueprint^™products, creating multiple opportunities to increase engagement across all brands.

“We welcome Nutrisystem’s powerful brands and talented team to the Tivity Health family. Both Nutrisystem and Tivity Health have successful track records improving health, both in the lives of consumers and health plan members, as well as in the communities where we do business. That experience, coupled with our shared commitment to our varied stakeholders, will power successful execution on the many opportunities that lie ahead,” said Donato Tramuto, Tivity Health’s Chief Executive Officer. “Since announcing the transaction, we have received overwhelmingly supportive feedback from our health plan customers, members and fitness partners about their interest in the broad array of offerings of our combined company. Our integrated approach – which addresses many of the social determinants of health fundamental to wellness – includes fitness, nutrition and social isolation, and represents a powerful offering to support healthier lifestyles, combat chronic conditions and lower medical costs. Tivity Health is now a formidable player in where the market is going – moving away from merely ‘sick care’ toward fully addressing healthcare.”

Comprehensive Integration Planning

As previously announced, Tivity Health will maintain all existing Nutrisystem brands, as well as Nutrisystem’s Fort Washington, Pennsylvania location. Dawn Zier has been named President and Chief Operating Officer of Tivity Health, reporting to Tivity Health CEO Donato Tramuto, and will join Tivity Health’s Board of Directors. She will be responsible for Tivity Health’s Healthcare and Nutrition divisions. Steve Janicak, formerly Chief Growth Officer at Tivity Health, has been named Division President, Healthcare. Keira Krausz, formerly Chief Marketing Officer at Nutrisystem, has been named Division President, Nutrition.

“Since the announcement of the transaction in December, we’ve been working on plans for a smooth integration that will allow us to quickly capture significant revenue and cost synergies across the combined company,” Zier said. “We’ve assembled a strong and experienced leadership team that will be focused on rapidly bringing an integrated suite of offerings to market. I am excited for this new chapter and strongly believe Tivity Health’s expertise in fitness and deep relationships in healthcare, combined with Nutrisystem’s nutrition and consumer engagement and marketing expertise, can change the paradigm for health and wellness and provide significant growth opportunities as we go forward.”
