WASHINGTON, D.C. — (July 31, 2013) — The Advisory Board Company (NASDAQ: ABCO) today announced financial results for the quarter ended June 30, 2013, which is the first quarter of its 2014 fiscal year. Revenue for the quarter increased 18.3% to $123.2 million, from $104.1 million for the quarter ended June 30, 2012. Contract value increased 15.6% to $475.8 million as of June 30, 2013, up from $411.6 million as of June 30, 2012. For the quarter ended June 30, 2013, net income attributable to common stockholders was $3.7 million, or $0.10 per diluted share, compared to net income attributable to common stockholders of $3.8 million, or $0.11 per diluted share, for the quarter ended June 30, 2012. For the quarter ended June 30, 2013, adjusted EBITDA was $22.5 million, up from $20.2 million for the quarter ended June 30, 2012. Adjusted net income for the quarter ended June 30, 2013 was $11.4 million, or $0.31 per diluted share, compared to $11.1 million, or $0.31 per diluted share, for the quarter ended June 30, 2012. Adjusted EBITDA, adjusted net income, and non-GAAP earnings per diluted share are all non-GAAP financial measures.

Robert Musslewhite, Chairman and Chief Executive Officer of The Advisory Board Company, commented, “Our continued strong performance this quarter is due to the superior value we provide to our members through our comprehensive portfolio of offerings, outstanding member service, and excellent product quality.  Our health care and higher education members face tremendous complexity due to demographic shifts, revenue pressure, a new value orientation, and business model transformations.  It is a testament to the work that we do that we are their partner of choice as they seek both to enhance performance in the current environment and to set strategy to succeed in the future.”  

Mr. Musslewhite continued, “I am also pleased to announce today the launch of the Student Success Performance Program, our first renewable software-based program for the higher education market.  With national five-year graduation rates barely above 50% and public and private funders demanding better performance, improving student success is a top priority for colleges and universities.  Leveraging the most innovative ideas from higher education and other industries, the Student Success Performance Program combines technology, research, and predictive analytics to help institutions positively inflect outcomes with at-risk and off-path students.”

Mr. Musslewhite concluded, “The program is off to a good start, with a robust charter membership that includes Rutgers University, Indiana University, University of Missouri, University of North Florida, and Georgia State University.  We are excited about the growth potential of software-based memberships for the higher education market, and we view this launch as the first step in leveraging the platform that our research has created to build a business serving colleges and universities with our software and analytics.”

Acquisition

The Company announced the acquisition as of July 8, 2013 of a technology firm to supplement its existing physician referral programs. Mr. Musslewhite commented, “We are always looking for new product offerings to supplement our portfolio of software-based tools and to contribute to our medium- and longer-term growth. Physician referrals continues to be an important issue for our members, who seek solutions that are valuable not only under today’s fee-for-service reimbursement structures but also under the integrated, risk-based models of care that are likely to become increasingly prevalent in the future.  We expect that this acquisition will complement and bolster our work with the large and growing Crimson Market Advantage membership and will support future new product launches in this space.”

Outlook for Calendar Year 2013 

The Company is updating its revenue guidance for calendar year 2013 to a range of approximately $500 million to $505 million, from a previous range of $495 million to $505 million.  The Company is also updating its guidance for calendar year 2013 adjusted EBITDA and non-GAAP earnings per diluted share to reflect the impact of the recent acquisition.  The Company expects calendar year 2013 adjusted EBITDA to be in a range of approximately $87.5 million to $92.5 million, from a previous range of $90 million to $95 million, and non-GAAP earnings per diluted share to be in a range of approximately $1.15 to $1.25, from a previous range of $1.18 to $1.28.  For calendar year 2013, the Company expects share-based compensation expense to be approximately $17.5 million, and amortization of acquisition-related intangible assets to be in a range of $7 million to $8 million.  For fiscal year 2014, the Company expects an effective tax rate in a range of approximately 38% to 39%. The Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013 contains information on how we calculate adjusted EBITDA and non-GAAP earnings per diluted share.

Non-GAAP Financial Measures

This press release and the accompanying tables present information about the Company’s adjusted EBITDA, adjusted net income, and non-GAAP earnings per diluted share, which are non-GAAP financial measures provided as a complement to the results provided in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The term “adjusted EBITDA” for the three months ended June 30, 2013 and 2012 refers to net income attributable to common stockholders before adjustment for the items set forth in the first table. The term “adjusted net income” for the three months ended June 30, 2013 and 2012 refers to net income attributable to common stockholders excluding the net of tax effect of the items set forth in the second table below. The term “non-GAAP earnings per diluted share” for the three months ended June 30, 2013 and 2012 refers to earnings per diluted share excluding the net of tax effect of the items set forth in the third table below.

A reconciliation of the foregoing historical non-GAAP financial measures to the most directly comparable historical GAAP financial measures is provided below for each of the periods indicated. It is not practicable to provide a reconciliation of forecasted adjusted EBITDA or non-GAAP earnings per diluted share to the most directly comparable GAAP financial measures because certain items required for the forecast of such GAAP financial measures, including fair value adjustments to acquisition-related earn-out liabilities, equity in loss of unconsolidated entity, and gains and losses on investment in common stock warrants, cannot reasonably be estimated or predicted at this time.
