Catasys Reports Second Quarter 2015 Financial Results

Reports Significant Growth in Enrollment, up 102% over Sequential Quarter

LOS ANGELES, August 17, 2015 -- Catasys, Inc. (OTCQB: CATS), a provider of proprietary big data-based, analytics-driven health management services to health insurers and employers, today reported second quarter financial results for the period ended June 30, 2015.

Second Quarter 2015 Financial and Operational Highlights:

Rick Anderson, President and COO said, “Our second quarter continued to generate top line growth, showing a 51% increase year-over-year. We are also pleased to report 102% sequential growth in enrollment in the second quarter of 2015 over our first quarter of 2015. Enrollment growth is anticipated to translate to increased revenue and deferred revenue in future quarters as the Company receives monthly fees or fee-for-service payments for these members throughout their term of enrollment. This was a result of expanding our OnTrak program into Illinois with a new health insurer, enrolling members suffering from anxiety disorder into our OnTrak program in Kansas and growth in enrollment for customers launched within the last year. During the quarter, we released results from a one-year retrospective cohort study in which we collaborated with Humana. The study found that our integrated substance abuse treatment program led to higher enrollment, fewer ER visits and inpatient hospitalizations and lower health care costs. Lastly, with the announcement of our warrant exchange, we eliminated an associated liability of approximately $38 million associated with those warrants. This represents an important step in moving the Company towards our goal of meeting the stockholders' equity test for listing on a national exchange. We look forward to keeping our shareholders updated on this progress.”

Second Quarter 2015 Results of Operations

For the second quarter ended June 30, 2015, total revenues increased by 51% to $472,000, compared to $312,000 for the second quarter 2014. The Company also reported $853,000 in deferred revenue, an increase of $338,000 or 65% compared to $515,000 for the first quarter of 2015. Depending on the customer, deferred revenue is either recognized over the course of the 52 week program when fees are received in advance, or annually when savings calculations are completed in cases where fees are subject to achieving savings at least equal to program fees. Catasys has been able to record its deferred revenue as actual revenue during the course of the business cycle, except for limited cases where members terminated from the program early. Total revenue increases were driven by an expansion of our customer base and health plan populations covered under our program.

The Company reported a net loss of ($587,000), or  ($0.02) per basic and diluted share for the second quarter ended June 30, 2015, compared to a net loss of ($27.4 million), or ($1.27) per basic and diluted share, for the second quarter of the prior year.

Total operating expenses for the second quarter 2015 were $2.98 million compared to $2.0 million for same quarter last year, primarily due to the higher cost of healthcare services based on increasing enrollment and non-cash general and administrative expenses.

General and administrative expense increased to $2.4 million for the three months ended June 30, 2015, compared to $1.7 million during the same period in 2014. This was primarily due to non-cash compensation expense for stock option grants to the members of the board of directors.
