HMS HOLDINGS CORP. REPORTS SECOND QUARTER 2014 RESULTS

·                  GAAP EPS of $0.07 and Adjusted EPS of $0.14 per share

·                  Medicaid Coordination of Benefits Revenue Up 9% y/y

·                  Commercial Market Revenue Up 14% y/y

·                  State Government Market Revenue Up 4% y/y

·                  Operating Expenses Declined 5% y/y

·                  Non-Medicare RAC Revenue Growth and Margin Expansion on Track to Meet Previously Announced Full-Year Projections

IRVING, TEXAS, August 8, 2014—HMS Holdings Corp. (NASDAQ: HMSY) today announced financial results for its second quarter ended June 30, 2014. Net income for the quarter was $6.0 million or $0.07 per fully diluted share, compared to net income of $3.4 million or $0.04 per fully diluted share in the prior quarter and $10.4 million or $0.12 per fully diluted share in the prior year second quarter. Adjusted EPS was $0.14, compared to $0.11 in the prior quarter and $0.20 in the prior year second quarter.  Revenue increased 8% to $112.6 million compared to revenue of $104.7 million in the prior quarter.  Revenue for the same period one year ago was $125.8 million.

“Our solid second quarter results reflect the positive effects of Medicaid expansion, increasing demand for our cost containment services and further operating expense savings,” said Bill Lucia, President and CEO. “A strong first half of 2014 reinforces our belief that we can achieve the previously announced margin expansion of 5-6% and revenue growth of 10-11% in our non-Medicare RAC business.”

The Company saw an increase of 1.5 million new Medicaid lives in its client eligibility data this quarter, a direct result of the expansion attributable to the Affordable Care Act. This increase generated revenue growth both in the state government and commercial markets and also in the Medicaid Coordination of Benefits product line, which increased 9% over the same period a year ago and 16% over the prior quarter.

“Strong sales performance, together with the growth in Medicaid lives in the quarter, resulted in a 14% increase in commercial market revenue over the same period last year and 20% over the prior quarter,” said Doug Williams, President of Commercial Markets. Revenue in the Company’s state government market grew 4% year over year and 6% over the prior quarter, despite the continued shift of lives into managed care.

“The prolonged re-procurement of the Medicare RAC contract continues to negatively impact total revenue, but we are increasingly enthusiastic about the growth opportunities in front of us in our state government and commercial markets during the balance of this year and beyond,” said

Lucia. “We are executing on our strategic plan in order to achieve our 2014 revenue growth and margin expansion targets, and we remain hopeful that the new Medicare RAC contracts will be awarded by CMS in the near future,” concluded Lucia.

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.
