By the numbers

Tivity's top-line performance improved nicely in the first quarter. Revenue jumped 43% year over year to $214.1 million. Analysts estimated that the company's revenue for the first quarter would come in at $153.92 million.

The company announced GAAP net income of $4.2 million, or $0.10 per share, in the first quarter. This represented an 80% decrease from GAAP earnings of $21.3 million, or $0.49 per diluted share, reported in the same quarter of 2018.

On a non-GAAP adjusted basis, Tivity's net income in the first quarter was $21.9 million, or $0.51 per share. This reflected a 3% increase from the prior-year period adjusted net income of $21.3 million, or $0.49 per share. Wall Street analysts estimated that Tivity would post earnings of $0.53 per share in the quarter.

Behind the numbers

Tivity's healthcare segment generates the lion's share of its revenue. Sales for the segment increased by 4.4% year over year to $156.5 million in the first quarter. This rise was driven by an increase in higher Prime Fitness subscriptions and more SilverSneakers visits.

The company also now has a nutrition segment, which includes products and solutions from the legacy Nutrisystem business. Tivity's acquisition of Nutrisystem closed in March. The company reported revenue for the nutrition segment of $57.6 million during the 24-day period between March 8, 2019, and March 31, 2019.

Tivity Health's GAAP earnings plunged from the prior-year period due to significantly higher spending levels. The company's operating expenses increased across the board. However, Tivity's non-GAAP adjusted earnings figures looked much better because they excluded costs related to the acquisition of Nutrisystem.

Looking ahead

Tivity expects that revenue for full-year 2019 will be between $1.15 billion and $1.18 billion. The company anticipates GAAP earnings per share (EPS) of $1.35 to $1.67, with adjusted non-GAAP EPS between $2.24 and $2.52.

CEO Donato Tramuto said that the company plans to "leverage Nutrisystem's media and marketing expertise to further increase enrollment and engagement in SilverSneakers and Prime Fitness." CFO Adam Holland added that integration efforts should enable Tivity to remain on track in achieving cost synergies this year between $9 million and $12 million.

Tramuto also noted that Medicare Advantage plans will soon be available to "provide coverage for a wider variety of benefits that are not primarily health-related." This could boost Tivity's revenue in future quarters.
