IRVING, TX., November 8, 2013—HMS Holdings Corp. (NASDAQ: HMSY) today announced financial and operating results for the third quarter of 2013.

Q3 2013 Financial Summary

For the quarter ended September 30, 2013, HMS reported revenue of $127.8 million, an increase of 12.8% compared to revenue of $113.2 million for the same period a year ago. Net income for the quarter was $11.5 million or $0.13 per fully diluted share compared to net income of $10.5 million or $0.12 per fully diluted share for the same period a year ago. Adjusted EPS for both the current and prior year quarter was $0.20.  The company also incurred $4.2 million in non-recurring legal and restructuring charges in the quarter, which has a $0.03 negative impact on both GAAP and adjusted EPS.

For the nine months ended September 30, 2013, HMS reported revenue of $370.2 million, an increase of 8.7% compared to revenue of $340.6 million for the same period a year ago. Net income for the nine months ended September 30, 2013 was $28.9 million or $0.32 per fully diluted share compared to net income of $30.5 million or $0.35 per fully diluted share for the same period a year ago. Adjusted EPS decreased 5.2% year over year to $0.55.

“Our third quarter results demonstrate a continued resumption of growth across our products and markets as we and our clients prepare for full implementation of the ACA in 2014,” said Bill Lucia, Chief Executive Officer. “While this translates to year over year improvements in our performance, it is clear that our full year growth will not be as strong as we had anticipated. As a result, we are tightening 2013 revenue guidance to the lower end of our original guidance of $495.0 to $525.0 million to a range of $495.0 to $510.0 million. Due to lower than anticipated revenues and certain one-time charges in the quarter, we are also revising fully diluted GAAP EPS to $0.44-$0.51 from $0.57-$0.63 and adjusted EPS to $0.75- $0.82 from $0.89-$0.95.”

Lucia added, “HMS would typically provide initial 2014 guidance this quarter. However, the impending Medicare RAC procurement and the ongoing audit scope and rule changes by CMS create a wide range of negative outcomes with probabilities that are so varied that we cannot provide meaningful guidance for 2014 until CMS has clarified its intentions related to the Medicare RAC procurement and program.  We now expect to provide full year guidance at the time of our February 2014 earnings call.”

“The Medicare RAC contract aside, we expect that 2014 will bring sizeable and long-term opportunities to our business,” remarked Lucia. “We believe that the ACA-driven growth in Medicaid and managed care programs, as well as our increasing presence in the commercial market, position us for a return to robust growth and enhanced profitability across the core of our business.”

Use of Non-GAAP Financials

This press release includes presentations of earnings before interest, taxes, depreciation and amortization (EBITDA) and adjusted EBITDA.  Adjusted EBITDA represents EBITDA adjusted for stock-based compensation expense.  EBITDA is a measure commonly used by the capital markets to value enterprises.  EBITDA is a non-GAAP financial measure and is reconciled to income before income taxes, which the Company’s management believes to be the most comparable generally accepted accounting principles (“GAAP”) measure.  Adjusted EBITDA results are calculated by adjusting GAAP income before income taxes to exclude the effects of depreciation, amortization of intangible assets, stock-based compensation expense, and net interest expense.

This press release also includes presentations of adjusted EPS. Adjusted EPS represents EPS adjusted for stock-based compensation expense and amortization of intangibles and for the related taxes for these adjustments. Adjusted EPS is a non-GAAP financial measure and is reconciled to EPS, which the Company’s management believes to be the most comparable GAAP measure.

The Company uses these non-GAAP financial measures for internal management purposes, when publicly providing guidance on possible future results, and as a means to evaluate period-to-period comparisons.  The Company’s management believes that these non-GAAP financial measures are a common measure used by investors and analysts to evaluate its performance.  These non-GAAP financial measures are used in addition to and in conjunction with results presented in accordance with GAAP and reflect an additional way of viewing aspects of the Company’s operations that, when viewed with GAAP results and the accompanying reconciliations to corresponding GAAP financial measures, provides a more complete understanding of the results of operations and trends affecting the Company’s business.  These non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, income before income taxes in accordance with GAAP.
