FOR IMMEDIATE RELEASE

Morningstar, Inc. Reports First-Quarter 2014 Financial Results

CHICAGO, April 23, 2014—Morningstar, Inc. (NASDAQ: MORN), a leading provider of independent investment research, today announced its first-quarter 2014 financial results. The company reported consolidated revenue of $181.2 million, a 7.3% increase from $168.9 million in the first quarter of 2013. Consolidated operating income was $38.5 million, down 5.0% from $40.6 million in the same period a year ago. Net income was $26.4 million, or 58 cents per diluted share, in the first quarter of 2014, compared with $29.6 million, or 63 cents per diluted share, in the first quarter of 2013.

Excluding acquisitions and a slight negative effect from foreign currency translations, revenue rose 6.9% in the first quarter of 2014. Revenue excluding acquisitions and foreign currency translations (organic revenue) is a non-GAAP measure; the accompanying financial tables contain a reconciliation to consolidated revenue.

Joe Mansueto, chairman and chief executive officer of Morningstar, said, “Organic revenue growth picked up slightly in the first quarter of 2014, and we continued investing in our existing business as well as in a number of promising initiatives. We hired about 200 new employees year over year, including for product and technology roles in the United States as well as data analysts based in India. While these investments added to our operating expense for the quarter, we see many opportunities to build shareholder value over the long term.”

Financial Highlights

Revenue and Key Operating Metrics

·                  Investment information revenue was $141.3 million, a 4.6% increase from $135.1 million in the first quarter of 2013. Morningstar Data, Morningstar Direct, and Morningstar Advisor Workstation were the main contributors to revenue growth. These positive results were partially offset by a $2.3 million revenue decline for Principia. The company has been migrating Principia clients to Morningstar Advisor Workstation and other Morningstar products and expects to continue supporting clients using Principia until the end of 2014.

·                  Investment management revenue was $39.9 million, an 18.1% increase from $33.8 million in the first quarter of 2013. Retirement Solutions and Morningstar Managed Portfolios were the main contributors to revenue growth, and revenue for Investment Advisory services was up slightly versus the same period of 2013.

·                  Consolidated operating income was $38.5 million in the first quarter of 2014, a 5.0% decrease from the same period in 2013. Operating expense rose $14.3 million, or 11.2%, in the first quarter of 2014, mainly because of higher salary and other compensation-related expense from additional headcount.

·                  Operating margin was 21.3% in the first quarter of 2014, down from 24.0% in the same period in 2013.

Cash Flow and Balance Sheet

·                  Morningstar generated negative free cash flow of $8.9 million in the first quarter of 2014, reflecting positive cash provided by operating activities of $11.9 million less $20.8 million of cash used for capital expenditures. 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. The company made bonus payments of $39.8 million in the first quarter of 2014, compared with $36.6 million in the first quarter of 2013. Morningstar typically pays annual bonuses in the first quarter. As a result, first-quarter operating cash flow tends to be lower compared with subsequent quarters.

·                  As of March 31, 2014, cash, cash equivalents, and investments totaled $264.0 million, compared with $298.6 million as of Dec. 31, 2013. Of the $700 million authorized under its share repurchase program, Morningstar had purchased a total of 7.4 million shares for $471.5 million as of March 31, 2014. In the first quarter of 2014, Morningstar repurchased approximately 280,000 shares for $21.7 million.

·                  On April 1, 2014, the company used approximately $28 million in cash to acquire ByAllAccounts, Inc., a provider of innovative data aggregation technology for financial applications, to enhance many of its key solutions across core customer groups, particularly offerings that support an advisor’s workflow.

·                  The company expects to pay approximately $7.6 million for its regular quarterly dividend on April 30, 2014.

Comparability of Year-Over-Year Results

Several items affected the comparability of first-quarter 2014 results versus the same period in 2013:

·                  Morningstar moved to a more centralized organizational structure in 2013. As a result, approximately 180 net positions shifted from the general and administrative and sales and marketing categories to cost of revenue. For the first quarter of 2014 compared with the same period in 2013, changes related to the company’s more centralized organizational structure added approximately $7 million of compensation expense to cost of revenue. At the same time, these changes reduced compensation expense in the sales and marketing and general and administrative expense categories by approximately $4 million and $3 million, respectively.

·                  As a result of a change in accounting estimate involving revenue recognition for certain investment management contracts with minimum fee features, Morningstar recognized an additional $1.7 million of investment management revenue in the first quarter of 2014 that will not recur in future quarters.

2

·                  During the first quarter of 2014, commission expense rose $2.9 million compared with the prior-year period, mainly because of a change to the company’s sales commission structure that requires a different accounting treatment. Morningstar now expenses sales commissions as incurred instead of amortizing them over the term of the underlying contracts. The company continues to amortize the prepaid commission balance from the previous commission structure and expensed an additional $2.7 million of commission cost in the quarter. Morningstar expects to incur additional commission expense for the next several quarters because of this change.

Operating Highlights

·                  Licenses for Morningstar Direct rose 15.5% to 8,858.

·                  Assets under management and advisement for Retirement Solutions were approximately $68.0 billion as of March 31, 2014, versus $51.9 billion as of March 31, 2013. Assets under management and advisement for Morningstar Managed Portfolios were approximately $7.8 billion as of March 31, 2014, compared with $5.3 billion as of March 31, 2013. Both product lines benefited from strong market performance and asset inflows.

·                  Companies that offer variable annuities have continued to face difficult market conditions, which has prompted some of Morningstar’s clients to begin managing their fund-of-funds portfolios in-house instead of using outside subadvisors. Because of this trend, Investment Advisory assets under advisement as of March 31, 2014 were $12.0 billion lower versus the same date in 2013.

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.
