FOR IMMEDIATE RELEASE

Morningstar, Inc. Reports Fourth-Quarter, Full-Year 2013 Financial Results

CHICAGO, Feb. 12, 2014—Morningstar, Inc. (NASDAQ: MORN), a leading provider of independent investment research, today announced its fourth-quarter and full-year 2013 financial results. The company reported consolidated revenue of $180.5 million in the fourth quarter of 2013, a 5.8% increase from $170.6 million in the fourth quarter of 2012. Consolidated operating income was $41.9 million in the fourth quarter of 2013, an increase of 6.7% compared with $39.3 million in the same period a year ago. Net income from continuing operations was $31.3 million, or 68 cents per diluted share, in the fourth quarter of 2013, compared with $27.8 million, or 58 cents per diluted share, in the fourth quarter of 2012.

Excluding acquisitions, divestitures, and foreign currency translations, revenue rose 5.5% in the fourth quarter of 2013. Revenue excluding acquisitions, divestitures, and foreign currency translations (organic revenue) is a non-GAAP measure; the accompanying financial tables contain a reconciliation to consolidated revenue.

For the year ended Dec. 31, 2013, consolidated revenue was $698.3 million, an increase of 6.1% compared with $658.3 million in 2012. Consolidated operating income was $170.7 million in 2013, an increase of 13.3% compared with $150.7 million in 2012. Net income from continuing operations was $123.5 million, or $2.66 per diluted share, in 2013, compared with $102.9 million, or $2.10 per diluted share, in 2012.

Joe Mansueto, chairman and chief executive officer of Morningstar, said, “Despite a few headwinds, we had decent growth for the year, driven by strong results for Morningstar Direct, Morningstar Data, Morningstar Managed Portfolios, and Retirement Solutions. We had higher operating expense in the fourth quarter because of a step up in hiring as well as additional legal and professional fees. Overall, though, we’re pleased with organic revenue growth for the year and our prospects as we continue to focus on widening Morningstar’s economic moat.”

Mansueto outlined some of the company’s 2013 key accomplishments and challenges:

Accomplishments:

·                  Morningstar Managed Portfolios and Retirement Solutions showed year-over-year asset growth of approximately 55% and 40%, respectively. Assets under management for Morningstar Managed Portfolios were approximately $7.3 billion as of Dec. 31, 2013, up from $4.7 billion as of Dec. 31, 2012. Assets under management and advisement for Retirement Solutions were approximately $65.6 billion as of Dec. 31, 2013 versus $47.2 billion as of Dec. 31, 2012.

·                  Although growth was slightly lower versus previous years, licenses for Morningstar Direct rose 15.2% to 8,514 globally.

·                  We launched Morningstar® for iPad®, a comprehensive mobile offering that helps investors monitor the markets, track their portfolios, and research investments using Morningstar data and analysis.

·                  We’re seeing signs of increased engagement among individual investors. After five years of declines, we saw a slight increase in U.S. Premium Membership subscriptions.

·                  Our research innovations continue to gain traction. We topped all firms in The Wall Street Journal’s 21st annual “Best on the Street” analysts survey with 13 winners—eight of whom ranked number one in their respective industries. We also rolled out quantitative ratings and reports for approximately 28,000 equities globally, and we introduced the Morningstar® Analyst Rating™ for target-date funds.

·                  We increased our quarterly dividend by 36% from 12.5 cents to 17 cents per share. We returned $17.4 million to shareholders through dividends and $153.5 million through stock buybacks, while maintaining our strong balance sheet.

Challenges:

·                  We’re still developing the next-generation software for our investment research platforms, and the initiative has taken longer than expected.

·                  We moved to a more centralized organizational structure and made other changes to better serve our core customer groups. Adjusting to our new structure took time and focus throughout the company during the year.

·                  Companies that offer variable annuities have continued to face difficult market conditions, which has prompted some of our clients to begin managing their fund-of-funds portfolios in-house instead of using outside subadvisors. Because of this trend, our Investment Advisory revenue was about $7.2 million lower in 2013 versus 2012, and assets under advisement for these services were down $10.8 billion over the same period.

·                  Despite margin improvement for the year, operating expense rose during the fourth quarter.

·                  Even though equity markets were significantly stronger in 2013, many of our clients remained cautious about spending.

Financial Highlights

·                  Investment information revenue was $143.3 million in the fourth quarter of 2013, an increase of 4.1% from $137.7 million in the fourth quarter of 2012. Morningstar DirectSM and Morningstar® Data were the largest contributors to revenue growth. Morningstar® Advisor WorkstationSM (including Morningstar OfficeSM) also contributed to the revenue increase, which was partially offset by lower revenue for Morningstar® Principia®.

·                  Investment management revenue was $37.2 million in the fourth quarter of 2013, an increase of 12.9% from $32.9 million in the fourth quarter of 2012. The main contributors to revenue growth were Morningstar® Managed PortfoliosSM and Retirement Solutions, reflecting strong market performance and asset inflows.

·                  Operating margin was 23.2% in the fourth quarter of 2013, up from 23.0% in the same period in 2012. Salary expense rose $3.7 million in the fourth quarter compared with the prior-year period. A $3.1 million increase in professional fees (including legal expense) also contributed to the growth in operating expense for the quarter. Morningstar’s fourth-quarter 2012 results included $3.2 million of additional stock-based compensation expense for accelerated vesting of restricted stock issued to a former executive. For the full year, operating margin was 24.4%, compared with 22.9% in 2012.

·                  In the fourth quarter of 2013, the company increased its share repurchase authorization by $200 million. Morningstar ended the year with 45.0 million shares outstanding and $250.2 million remaining for share repurchases under its buyback program.

·                  The company generated positive free cash flow of $48.8 million in the fourth quarter of 2013 and $153.1 million for the full year. Free cash flow is a non-GAAP measure; the accompanying financial tables contain a reconciliation to cash provided by operating activities. Morningstar defines free cash flow as cash provided by or used for operating activities less capital expenditures.

·                  As of Dec. 31, 2013, Morningstar had cash, cash equivalents, and investments of $298.6 million. The company expects to make annual bonus payments of approximately $40 million in the first quarter of 2014, compared with $36 million in the first quarter of 2013.

Caution Concerning Forward-Looking Statements

This press release contains forward-looking statements as that term is used in the Private Securities Litigation Reform Act of 1995. These statements are based on our current expectations about future events or future financial performance. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, and often contain words such as “may,” “could,” “expect,” “intend,” “plan,” “seek,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” or “continue.” These statements involve known and unknown risks and uncertainties that may cause the events we discuss not to occur or to differ significantly from what we expect. For us, these risks and uncertainties include, among others, general industry conditions and competition, including current global financial uncertainty; the impact of market volatility on revenue from asset-based fees; damage to our reputation resulting from claims made about possible conflicts of interest; liability for any losses that result from an actual or claimed breach of our fiduciary duties; financial services industry consolidation; liability related to the storage of personal information about our users; a prolonged outage of our database and network facilities; challenges faced by our non-U.S. operations; the availability of free or low-cost investment information; and liability and/or damage to our reputation as a result of some of our currently pending litigation. A more complete description of these risks and uncertainties can be found in our filings with the Securities and Exchange Commission, including our Annual Report on Form 10-K for the year ended December 31, 2012. If any of these risks and uncertainties materialize, our actual future results may vary significantly from what we expected. We do not undertake to update our forward-looking statements as a result of new information or future events.

Non-GAAP Financial Measures

To supplement Morningstar’s consolidated financial statements presented in accordance with U.S. Generally Accepted Accounting Principles (GAAP), Morningstar uses the following measures considered as non-GAAP by the U.S. Securities and Exchange Commission: free cash flow, consolidated revenue excluding acquisitions and foreign currency translations (organic revenue), and international revenue excluding acquisitions and foreign currency translations. These non-GAAP measures may not be comparable to similarly titled measures reported by other companies.

Morningstar presents free cash flow solely as supplemental disclosure to help investors better understand how much cash is available after Morningstar spends money to operate its business. Morningstar uses free cash flow to evaluate its business. Free cash flow should not be considered an alternative to any measure required to be reported under GAAP (such as cash provided by (used for) operating, investing, and financing activities). For more information on free cash flow, please see the reconciliation from cash provided by operating activities to free cash flow included in the accompanying financial tables. Morningstar presents consolidated revenue excluding acquisitions and foreign currency translations (organic revenue) and international revenue excluding acquisitions and foreign currency translations because the company believes these non-GAAP measures help investors better compare period-to-period results. For more information, please see the reconciliation provided in the accompanying financial tables.

All dollar and percentage comparisons, which are often accompanied by words such as “increase,” “decrease,” “grew,” “declined, “or “was similar” refer to a comparison with the same period in the previous year unless otherwise stated.

In addition, we took this opportunity to revise our revenue by product structure to better represent how management internally reviews and evaluates product revenue and performance. The most significant revision is that Morningstar Data now excludes Morningstar Commodity Data. We have reclassified the prior-year information to reflect these changes.
