Diluted Income Per Share Increased 10% to $0.54 for Third Quarter 2018

Company Expects to Achieve Full Year 2018 Revenue, Diluted Income Per Share and Adjusted EBITDA Guidance Ranges

Board Authorizes New $75 Million Stock Repurchase Program

Fort Washington, PA—October 30, 2018—Nutrisystem, Inc. (Nasdaq: NTRI), a leading provider of health and wellness and weight management products and services including Nutrisystem® and South Beach Diet® brands, today reported financial results for the quarter and nine months ended September 30, 2018.  

Dawn Zier, President and Chief Executive Officer, stated, “I’m pleased we delivered year-over-year growth in the third quarter and adjusted EBITDA and earnings per share are aligned with expectations. South Beach growth remains strong and, most importantly, we see a clear path to return the Nutrisystem brand to growth in 2019.” 

Ms. Zier added, “During the second half of the year we’re focused on positioning our company for a return to meaningful growth in 2019. We’re doing this in three primary ways and have arrived at the proof points that give us confidence that our plans will deliver that. First, our innovation efforts are centered around personalized nutrition and flexibility to better engage with consumers both at the start and throughout their journey to optimal health. Second, our new creative for 2019 supports our evolving brand promise, resonates well with consumers, and we’re seeing early evidence that our creative approach will drive response and engagement. And finally, we’re actively refining our media deployment strategy to expand reach, grow digital, and increase marketing efficiency. We’re excited about our future.”

The following are key financial highlights for the period. Reconciliations of certain GAAP to non-GAAP measures are provided later in this press release.

Third Quarter 2018 Compared to Third Quarter 2017

Mike Monahan, Chief Financial Officer, commented, “Our third quarter and year-to-date results demonstrate the strength of our business model as we continued to generate increased free cash flow. Our strong balance sheet has allowed us to repurchase $26.3 million of stock in the first nine months of this year, and as of September 30, 2018, we had approximately $92.6 million in cash and cash equivalents and short-term investments, and no long-term debt. The Board of Directors has authorized a new $75 million buyback program set to expire October 2020. We will continue to utilize our balance sheet to enhance the long-term value of our company.”

In preparation of 2019, the Company has made some deliberate decisions around media deployment and media mix in the second half of the year that have had a small impact on current year revenue but position the Company more strongly for the new year. Reconciliations of certain GAAP to non-GAAP measures are provided later in this press release.

Non-GAAP Financial Measures  

Within this press release, the Company makes reference to a non-GAAP financial measure (adjusted EBITDA) which has a directly comparable GAAP financial measure (net income). EBITDA is defined as net income excluding interest, income taxes and depreciation and amortization. Adjusted EBITDA is defined as EBITDA excluding non-cash employee compensation expense and transaction costs related to stockholder cooperation agreement. The Company excludes non-cash employee compensation expense because it is a non-cash expense that is not reflective of the ongoing cash expense of the Company. The Company excludes the transaction costs as the matter was resolved and is not reflective of the ongoing operations of the Company. Adjusted EBITDA is provided so that investors have the same financial data that management uses to assess the Company’s operating results

with the belief that it will assist the investment community in properly assessing the ongoing performance of the Company for the periods being reported and future periods. The presentation of this additional information is not meant to be considered a substitute for measures prepared in accordance with GAAP.
