OWINGS MILLS, Md., November 5, 2015 – Medifast, Inc. (NYSE: MED), leading United States manufacturer and provider of clinically proven weight-loss and healthy living products and programs, today reported financial results for the third quarter ended September 30, 2015.

“Our top line results, solid gross margin expansion and expense leverage enabled us to generate earnings above our guidance for the third quarter,” said Michael C. MacDonald, Medifast Chairman and Chief Executive Officer. “We are pleased with the sequential improvement in our business and our meaningful progress to advance the growth and simplification of Take Shape For Life. Moving forward, our team remains focused on executing our strategic initiatives as we improve the efficiency across our differentiated sales channels to help drive higher revenues and profitability long-term.”

Third Quarter 2015 Results

Results from Continuing Operations

Income from continuing operations was $5.4 million, or $0.45 per diluted share, compared to $5.3 million, or $0.42 per diluted share, for the third quarter of 2014.

For the third quarter, Medifast net revenue from continuing operations decreased 4% to $65.9 million from net revenue of $69.0 million in the third quarter of 2014.

Revenue in the direct sales channel, Take Shape for Life, was $49.9 million in the third quarter of 2015, and this was consistent with the prior year third quarter. This is the third straight quarterly improvement in the quarterly year over year revenue trend and, in fact, the first quarter with flat to positive sales since Q4 2013 for Take Shape For Life.

The total number of active earning Health Coaches in the third quarter was 12,000 as compared to 12,400 in the third quarter of 2014. On a sequential basis, the number of active earning Health Coaches in the third quarter of 2015 increased by approximately 200 Health Coaches when compared to the second quarter of 2015. The average revenue per active earning Health Coach for the quarter was $4,145 as compared to $4,025 in third quarter of 2014.

The Company's Medifast Direct channel revenue decreased 16% to $11.2 million, compared to $13.4 million in the third quarter of 2014.  Revenue decreased year-over-year as new customer acquisition continues to be challenging. Advertising expense in the quarter was down 30% in part to align spending with the early October launch of the Medifast Achieve Plan.

Revenue in the Franchise Medifast Weight Control Centers channel decreased 5% to $4.0 million from $4.2 million in the third quarter of last year. The decrease in revenue was primarily driven by fewer franchise centers in operation during the period and a slight decrease in sales per center. There were 62 franchise centers in operation at the end of third quarter 2015 compared to 69 centers at the end of the same period last year.

In the third quarter, the Wholesale channel revenue decreased to $0.8 million, compared to $1.5 million in the same period last year. This decrease was due to the loss of certain accounts resulting from Medifast enforcement of business partner compliance requirements.

Gross profit for the third quarter of 2015 was $49.2 million, compared to $50.7 million in the third quarter of 2014. The Company's gross profit as a percentage of net revenue increased 110 basis points to 74.6% from 73.5% in the third quarter of 2014. The increase from the prior year was primarily the result of price increases taken earlier this year and improved manufacturing and shipping efficiencies recognized during the quarter.

Selling, general and administrative expenses (“SG&A”) decreased $2.9 million to $41.2 million compared to $44.1 million in the third quarter of 2014. As a percentage of net revenue, SG&A expense decreased 150 basis points to 62.5% versus 64.0% in the third quarter of 2014.

Sales and marketing expense decreased $1.4 million in the third quarter of 2015 compared to the third quarter of 2014, primarily driven by a reduced advertising spend and a decrease in expenses associated with the Take Shape For Life® annual convention.

The third quarter 2015 effective tax rate was 33.4% compared to 29.7% in the third quarter of 2014. This increase was due to the decrease in permanent differences primarily driven by lowering the benefits of the domestic manufacturing deduction and research and development credits taken in the prior year.

Discontinued Operations

As previously disclosed, the Company exited the Medifast Weight Control Center corporate model with the sale of 41 centers to existing franchise partners (24 centers were sold in June 2014 and the remaining 17 centers were sold in December 2014) and the closure of the remaining 34 corporate centers. For the third quarter of 2015, corporate-owned Medifast Weight Control Centers had income from discontinued operations, net of tax, of $0.1 million.

Balance Sheet 

The Company's balance sheet remains strong with stockholders' equity of $86.8 million and working capital of approximately $63.3 million as of September 30, 2015.  Cash, cash equivalents, and investment securities increased $13.9 million to $66.5 million compared to $52.6 million at December 31, 2014.

The Company repurchased 261,211 shares of common stock for $7.2 million during the third quarter as part of its current share repurchase authorization. The Company has authorization to repurchase a total of approximately 850,000 shares. The Company remains free of interest bearing debt.

Outlook

The Company expects fourth quarter 2015 net revenue from continuing operations to be in the range of approximately $60.5 to $63.5 million and earnings per diluted share from continuing operations in the range of $0.31 to $0.35 per diluted share.

For fiscal year 2015, the Company now expects revenue from continuing operations to be in the range of $272.0 to $275.0 million and earnings per diluted share from continuing operations in the range of $1.72 to $1.76 per diluted share. The fiscal year 2015 guidance assumes a 34% to 35% effective tax rate.

Fiscal year guidance excludes expenses resulting from 13D filings.
