Manning & Napier, Inc. Reports Fourth Quarter and Year-End 2012 Earnings Results

FAIRPORT, NY, February 13, 2013—Manning & Napier, Inc. (NYSE: MN), (“Manning & Napier” or “the Company”) today reported 2012 fourth quarter and year-end results for the period ended December 31, 2012.

Summary Highlights

Patrick Cunningham, Manning & Napier’s Chief Executive Officer, commented, “2012 was a strong year for our investment products. Earlier in the year, we discussed certain market trends that have been working against the positioning of our portfolios and our active management approach. Our expectation was that our clients would benefit from our positioning once these headwinds began to dissipate. We saw just that in the latter half of 2012, which led to competitive absolute and relative returns for the full calendar year. The improving momentum in our short-term track record, in conjunction with our strong long-term track record, has already improved the service environment for our sales teams, and should help us return the business to a position of net inflows. We continue to believe that active management will play a critical role in meeting client objectives and their evolving needs. As such, we are making the necessary investments in our business and expanding our distribution capacity in terms of personnel, geographic focus and product diversification to ensure sustainable growth and stability for our business. Additionally, we are building track records and supporting new investment capabilities to broaden our product set coverage. With this focus, we believe we will continue to provide long-term value to our shareholders despite ongoing market uncertainties.”

Fourth Quarter 2012 Financial Review

Manning & Napier reported fourth quarter 2012 revenue of $87.1 million, an increase of 8% from revenue of $80.4 million reported in the fourth quarter of 2011, and an increase of 2% from revenue of $85.4 million reported in the third quarter of 2012. The changes in revenue resulted primarily from increases in average AUM. Average AUM for the quarter was $44.5 billion, which was a 9% and 3% increase over average AUM for the fourth quarter of 2011 and the third quarter of 2012, when average AUM was $40.7 billion and $43.2 billion, respectively. Revenue as a percentage of average AUM was 0.78% for the fourth quarter of 2012, compared with 0.79% for both the fourth quarter of 2011 and for the previous quarter.

Operating expenses were $73.9 million, or $46.7 million excluding non-cash reorganization-related share-based compensation of $27.2 million. The $46.7 million represents an increase of $6.2 million in expenses, compared with the fourth quarter of 2011, and an increase of $0.3 million in expenses compared with the third quarter of 2012, excluding reorganization-related share-based compensation. The increase in expenses in the current quarter compared with the fourth quarter of 2011 was due primarily to higher incentive compensation costs resulting from the strong absolute and relative investment performance during the fourth quarter of 2012 compared to the fourth

quarter of 2011 as well as increases in asset-based costs associated with our fund and collective products including sub-transfer agent fees, 12b-1 fees and fund fee caps.

Generally Accepted Accounting Principles (“GAAP”) based operating income was $13.2 million. Operating income, excluding non-cash reorganization-related share-based compensation, was $40.4 million for the quarter, an increase of $0.6 million over the fourth quarter of 2011 and an increase of $1.4 million from the third quarter of 2012. Operating margin, excluding non-cash reorganization-related share-based compensation expense, was 46% for the fourth quarter of 2012, compared with 50% for the fourth quarter of 2011 and 46% for the third quarter of 2012.

The Company uses economic income and economic net income to provide greater clarity regarding the cash earnings of the business by removing non-cash reorganization-related share-based compensation charges and non-cash interest expense on shares subject to mandatory redemption, as defined in the Non-GAAP Financial Measures section below. On this basis, Manning & Napier reported fourth quarter 2012 economic income of $40.5 million, compared with $40.0 million in the fourth quarter of 2011, and $39.6 million in the third quarter of 2012. Also for the fourth quarter of 2012, economic net income was $25.0 million, or $0.28 per adjusted share, compared with $24.7 million, or $0.27 per adjusted share in the fourth quarter of 2011, and $24.4 million, or $0.27 per adjusted share in the third quarter of 2012.

On a GAAP basis, net income attributable to the controlling and noncontrolling interests for the fourth quarter was $11.5 million, compared with net loss of $179.7 million in the fourth quarter of 2011 and net income of $21.1 million in the third quarter of 2012. The increase in net income compared to the fourth quarter of 2011 is attributable to the decrease in non-cash reorganization-related share-based compensation expense of $188.1 million, while the sequential decrease in net income is attributed to an increase in the non-cash reorganization-related share-based compensation expense of $9.9 million. GAAP net loss attributable to the common shareholders for the fourth quarter of $0.3 million, or $0.02 per basic and diluted share, reflects the public ownership of the Company’s subsidiary, Manning & Napier Group, LLC. The remaining ownership interest is attributed to the other members of Manning & Napier Group, LLC.

Full Year 2012 Financial Review

Manning & Napier reported 2012 revenue of $339.1 million, an increase of 3% over revenue of $330.0 million reported in 2011. The increase in 2012 was consistent with changes in average AUM, which also increased by 3% over the prior year. Revenue as a percentage of average AUM was 0.78% for the year, which is the same when compared with the prior year.

Operating expenses were $254.9 million, or $182.7 million excluding non-cash reorganization-related share-based compensation of $72.3 million. The $182.7 million represents a 5% increase from 2011, resulting from an investment in personnel related to distribution and infrastructure, coupled with increases in asset-based costs associated with our fund and collective products. GAAP-based operating income was $84.1 million for the year, and $156.4 million of operating income after excluding non-cash reorganization-related share-based compensation charges. The $156.4 million represents a $0.1 million decrease over 2011. Operating margin for 2012 year-to-date, excluding non-cash reorganization-related share-based compensation expense, was 46%, compared with 47% in 2011.

Manning & Napier reported 2012 economic income of $156.9 million, compared with $156.7 million in 2011. Also for 2012, economic net income was $96.9 million, or $1.08 per adjusted share, compared with $96.8 million, or $1.08 per adjusted share in 2011.

On a GAAP basis, net income attributable to the controlling and noncontrolling interests for 2012 was $76.4 million, compared with net loss of $106.4 million in 2011. The increase in the 2012 net income is attributed to the decrease in non-cash reorganization-related share-based compensation of $143.1 million when compared to 2011. GAAP net income attributable to the common shareholders for 2012 was $2.5 million, or $0.18 per basic and diluted share.

Assets Under Management

As of December 31, 2012, AUM was $45.2 billion, an increase of 2% from the $44.3 billion as of September 30, 2012 and 12% from the $40.2 billion as of December 31, 2011. As of December 31, 2012, the composition of the Company’s AUM was 55% in separate accounts and 45% in mutual funds and collective investment trusts, which is consistent with the composition as of September 30, 2012 and generally consistent with the AUM composition as of December 31, 2011 of 56% in separate accounts and 44% in mutual funds and collective investment trusts.

Since September 30, 2012, AUM increased by $0.9 billion, including increases of 1% in separate account AUM and 3% in mutual fund and collective investment trust AUM. The $0.9 billion increase in AUM from September 30, 2012 to December 31, 2012, was comprised of a $1.2 billion increase in market appreciation and $2.5 billion in client inflows. These increases were offset by client outflows of $2.8 billion. As it relates to the Company’s separate accounts, outflows were caused by withdrawals from existing client accounts, as the annualized separate account retention rate continues to remain at approximately 95% for 2012, which is in line with 96% for 2011.

When compared to December 31, 2011, AUM increased by $5.0 billion from $40.2 billion, including an increase of $2.0 billion, or 9%, in separate account AUM and an increase of $3.0 billion, or 17%, in mutual fund and collective investment trust AUM.

Balance Sheet Review

As of December 31, 2012, cash and cash equivalents was $108.3 million, compared with $97.0 million as of September 30, 2012. As a means to provide flexibility for possible future financing needs, we recently entered into an unsecured $10.0 million line of credit arrangement. We have not drawn down on the line of credit and we continue to have no debt outstanding.

Non-GAAP Financial Measures

To provide investors with greater insight, promote transparency and allow for a more comprehensive understanding of the information used by management in its financial and operational decision-making, the Company supplements its combined consolidated statements of income presented on a GAAP basis with non-GAAP financial measures of earnings. Please refer to the schedule in this release for a reconciliation of non-GAAP financial measures to GAAP measures.

Management uses economic income, economic net income and economic net income per adjusted share as financial measures to evaluate the profitability and efficiency of the Company’s business model. Economic income, economic net income and economic net income per adjusted share are not presented in accordance with GAAP. Economic income excludes from income before provision for income taxes:

Economic net income is a non-GAAP measure of after-tax operating performance and equals the Company’s economic income less adjusted income taxes. Adjusted income taxes are estimated assuming the exchange of all outstanding units of Manning & Napier Group, LLC into Class A common stock on a one-to-one basis. Therefore, all income of Manning & Napier Group, LLC allocated to the units of Manning & Napier Group, LLC is treated as if it were allocated to Manning & Napier and represents an estimate of income tax expense at an effective rate of 38.25% on economic income for each respective period, reflecting assumed federal, state and local income taxes.

Economic net income per adjusted share is equal to economic net income divided by the total number of adjusted Class A common shares outstanding. The number of adjusted Class A common shares outstanding for all periods presented is determined by assuming that all exchangeable units of Manning & Napier Group, LLC are converted into the Company’s outstanding Class A common stock as of the respective reporting date, on a one-to-one basis. The Company’s management uses economic net income, among other financial data, to determine the earnings available to distribute as dividends to holders of its Class A common stock and to the holders of the units of Manning & Napier Group, LLC.

Investors should consider the non-GAAP measures in addition to, and not as a substitute for, financial measures prepared in accordance with GAAP. Additionally, the Company’s non-GAAP measures may differ from similar measures used by other companies, even if similar terms are used to identify such measures.
