FOR IMMEDIATE RELEASE

Morningstar, Inc. Reports Second-Quarter 2013 Financial Results, Announces Operating Segment Change

CHICAGO, July 24, 2013—Morningstar, Inc. (NASDAQ: MORN), a leading provider of independent investment research, today announced its second-quarter 2013 financial results. The company reported consolidated revenue of $175.4 million in the second quarter of 2013, a 5.7% increase from $166.0 million in the second quarter of 2012. Consolidated operating income was $43.6 million in the second quarter of 2013, an increase of 6.0% compared with $41.1 million in the same period a year ago. Net income was $31.1 million, or 66 cents per diluted share, in the second quarter of 2013, compared with $27.9 million, or 56 cents per diluted share, in the second quarter of 2012. In May, Morningstar acquired an additional 76% of Morningstar Sweden AB to become sole owner. The company recorded a non-cash gain of $3.7 million, which increased net income for the quarter by 5 cents per diluted share.

Excluding acquisitions, divestitures, and foreign currency translations, revenue rose 6.6% in the second 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.

In the first six months of 2013, consolidated revenue was $344.3 million, an increase of 5.4% compared with $326.7 million in the same period in 2012. Consolidated operating income was $84.1 million in the first half of 2013, an increase of 17.6% compared with $71.5 million in the same period a year ago. Net income was $60.7 million, or $1.30 per diluted share, in the first half of 2013, compared with $48.0 million, or 95 cents per diluted share, in the same period in 2012.

Joe Mansueto, chairman and chief executive officer of Morningstar, said, “We had another solid quarter, with organic revenue growth of 6.6%, primarily driven by Morningstar Direct, Morningstar Managed Portfolios, and Retirement Solutions. Morningstar Data and Morningstar Advisor Workstation also had strong gains. Revenue for Investment Advisory Services was down year over year, but was higher than in the first quarter of this year.”

He added, “During the quarter, we significantly expanded our equity coverage with the launch of quantitative ratings and reports for 28,000 companies globally, and we introduced the next generation of Morningstar Retirement Manager, our advice and managed account platform for retirement plan participants. We held our 25th annual investment conference in Chicago, as well as conferences in London, Paris, Sydney, and Toronto. We became sole owners of Morningstar Sweden. And, we’re proud to report that Morningstar topped all firms in The Wall Street Journal’s “Best on the Street” analyst survey with 13 winners—eight of whom ranked number one.”

Operating Segment Change: Morningstar also announced that it will begin reporting in one operating segment to reflect its shift to a more centralized organizational structure. Morningstar will continue to report revenue for its Information and Investment Management product groups. The changes were effective July 1, 2013, and the company will begin reporting its financial results based on the new operating segment when it issues its third-quarter earnings press release.

International Operations: Revenue from international operations was $49.1 million in the second quarter of 2013, an increase of 2.2% from the same period a year ago. Excluding acquisitions, divestitures, and foreign currency translations, international revenue rose 5.0% in the second quarter. International revenue excluding acquisitions, divestitures, and foreign currency translations is a non-GAAP measure; the accompanying financial tables contain a reconciliation to international revenue.

Operating Income: Consolidated operating income was $43.6 million in the second quarter of 2013, a 6.0% increase from the same period in 2012. Operating expense rose $7.0 million, or 5.6%, in the second quarter of 2013. In the first six months of 2013, consolidated operating income rose 17.6% to $84.1 million compared with $71.5 million in the first half of 2012. Operating expense rose $4.9 million, or 1.9%, in the first half of 2013.

The largest factors behind the operating expense increase were salary expense, which rose $2.8 million, or approximately 4.8%, and bonus expense, which rose $2.2 million, or 30.1% in the second quarter of 2013. Of the increase in salary expense, approximately $1.5 million resulted from moving up the timing of

annual salary adjustments to April, from July previously. Salary increases made in July 2012 also contributed to the higher salary expense. The bonus expense increase mainly reflects the comparison from unusually low expense in the second quarter of 2012. Within operating expense, these salary and bonus items had the largest effect on the development and general and administrative cost categories. Morningstar reviews and updates its bonus expense quarterly based primarily on its expectations for full-year revenue and operating income metrics relative to internal targets. Also contributing to the increase was depreciation expense, which rose $1.3 million, or 27.7%, in the quarter, primarily driven by amortization of software development costs and higher capital expenditures for computer software in the United States.

Operating margin was 24.8% in the second quarter of 2013, in line with the same period in 2012. In the first six months of 2013, operating margin was 24.4%, compared with 21.9% in the first six months of 2012. Lower salary expense as a percentage of revenue contributed approximately 1.2 percentage points to the margin improvement in the first half of 2013.

The company had approximately 3,425 employees worldwide as of June 30, 2013, compared with 3,495 employees as of Dec. 31, 2012 and 3,490 employees as of June 30, 2012.

Effective Tax Rate: Morningstar’s effective tax rate in the second quarter of 2013 was 33.9%, compared with 34.6% in the same period in 2012. Year to date, the company’s effective tax rate was 31.8% compared with 35.3% in the first half of 2012. The decreases primarily reflect reductions in valuation allowances and, for the year-to-date period, adjustments to certain deferred income tax benefits.

Free Cash Flow: Morningstar generated positive free cash flow of $48.7 million in the second quarter of 2013, reflecting cash provided by operating activities of $58.5 million and $9.8 million of capital expenditures. Free cash flow rose by $8.5 million compared with the second quarter of 2012 as cash provided by operating activities rose $9.3 million, primarily because of the positive cash flow effect of operating assets and liabilities and the timing of income tax payments.

In the first six months of 2013, Morningstar generated free cash flow of $66.2 million, reflecting cash provided by operating activities of $85.1 million and capital expenditures of $18.9 million. Cash provided by operating activities in the first six months of 2013 increased $30.3 million, reflecting higher net income (adjusted for non-cash items), a $6.3 million decrease in bonuses paid in the first quarter of 2013, and a $6.9 million decrease in cash paid for taxes. Capital expenditures rose $1.0 million.

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 June 30, 2013, Morningstar had cash, cash equivalents, and investments of $314.8 million, compared with $321.4 million as of Dec. 31, 2012. In the first six months of 2013, the company used $53.9 million of cash for its share repurchase program and approximately $11.1 million of cash for the Sweden share acquisition. Of the $500 million authorized under the share repurchase program, Morningstar has purchased a total of 5.8 million shares for $352.9 million as of June 30, 2013. The company expects to pay approximately $5.8 million for its regular quarterly dividend on July 31, 2013.

Operating Segment Performance

Investment Information Segment: The largest products and services in this segment based on revenue are Morningstar® Data; Morningstar® Advisor WorkstationSM (including Morningstar Office); Morningstar DirectSM; and Morningstar.com®, including Premium Memberships and Internet advertising sales.

·                  Revenue was $141.4 million in the second quarter of 2013, up 5.0% from $134.7 million in the prior-year period. Morningstar Direct was the main contributor to organic revenue growth and Morningstar Data, Morningstar Advisor Workstation, and Morningstar.com also experienced growth. Licenses for Morningstar Direct rose 19.0% to 8,055. Revenue for Morningstar.com rose primarily because of higher advertising sales in the United States; U.S. Premium Membership subscriptions declined 2.0% to 123,881.

·                  Operating income was $44.8 million in the second quarter of 2013, compared with $43.0 million in the same period in 2012. Operating expense in this segment increased $4.8 million, or 5.3%, primarily because of higher bonus expense and salary expense.

·                  Operating margin declined slightly to 31.7% in the second quarter of 2013 versus 31.9% in the prior-year period.

Investment Management Segment: The largest products in this segment based on revenue are Investment Advisory Services; Retirement Solutions, including Advice by Ibbotson® and Morningstar® Retirement ManagerSM; and Morningstar® Managed PortfoliosSM.

·                  Revenue was $34.0 million in the second quarter of 2013, an 8.9% increase from $31.2 million in the same period in 2012. The main contributors to revenue growth were Morningstar Managed Portfolios and Retirement Solutions, reflecting market performance, asset inflows, and new clients. These revenue increases were partially offset by lower revenue for Investment Advisory Services. The variable annuity industry now represents 10% of revenue in this segment.

·                  Assets under advisement and management for Investment Advisory Services were $101.4 billion as of June 30, 2013, compared with $138.1 billion as of June 30, 2012, a decrease of $36.7 billion, or 26.6%.

A change in the scope of services Morningstar provides to an existing client during the fourth quarter of 2012 lowered assets under advisement by $45.9 billion. This portfolio represented 33.2% of Morningstar’s Investment Advisory Services assets under advisement and management as of June 30, 2012.

·                  Assets under management and advisement for Retirement Solutions were $55.9 billion as of June 30, 2013, versus $41.7 billion as of June 30, 2012.

·                  Operating income was $16.5 million in the second quarter of 2013, an increase of 22.6% compared with the second quarter of 2012. Operating expense in the segment was $17.5 million, a decrease of $0.3 million compared with the second quarter of 2012. Operating margin was 48.6% in the second quarter of 2013 versus 43.2% in the prior-year period because revenue growth exceeded the growth in operating expense.

Intangible Amortization and Corporate Depreciation Expense: Morningstar does not allocate expense for intangible amortization or corporate depreciation to its operating segments. Intangible amortization was $5.3 million in the second quarter of 2013, a decrease of $0.6 million compared with the same period in 2012. Corporate depreciation expense was $3.6 million in the second quarter, an increase of $1.2 million compared with the same period in 2012.

Corporate Unallocated: This category includes costs related to corporate functions, including general management, information technology used to support corporate systems, legal, finance, human resources, marketing, and corporate communications. It also includes capitalization of internal product development costs. Costs in this category were $8.9 million, an increase of $1.8 million, or 25.8%. Higher professional fees and salary expense both contributed to the increase.

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 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.
