Manning & Napier, Inc. Reports Second Quarter 2013 Earnings Results

FAIRPORT, NY, July 31, 2013—Manning & Napier, Inc. (NYSE: MN), (“Manning & Napier” or “the Company”) today reported 2013 second quarter results for the period ended June 30, 2013.

Summary Highlights

Patrick Cunningham, Manning & Napier’s Chief Executive Officer, commented, “We have continued to execute on our strategic objectives while experiencing consistent interest in our investment solutions from clients and prospects. In spite of continuing strong levels of gross inflows resulting from new accounts and client contributions, the second quarter witnessed outflows that outpaced inflows concentrated in platform business and U.S. Equity products. With more than 40 years of experience, we’ve seen firsthand how major points of inflection in the market can represent opportunities for active managers to achieve strong excess returns. Our long-term track records have been built upon taking advantage of the biases that can be created in extreme market environments. We continue to stay close to our clients and true to our investment discipline as this is core to delivering on expectations to our clients and shareholders.”

Second Quarter 2013 Financial Review

Manning & Napier reported second quarter 2013 revenue of $93.0 million, an increase of 14% from revenue of $81.5 million reported in the second quarter of 2012, and an increase of 3% from revenue of $90.3 million reported in the first quarter of 2013. The changes in revenue resulted primarily from increases in average AUM. Average AUM for the quarter was $47.8 billion, which was a 12% and 1% increase from the second quarter of 2012 and the first quarter of 2013, when average AUM was $42.8 billion and $47.2 billion, respectively. Revenue as a percentage of average AUM was 0.78% for the second quarter of 2013 compared with 0.76% for the second quarter of 2012 and 0.78% for the previous quarter.

Operating expenses were $71.6 million, or $48.8 million, excluding non-cash reorganization-related share-based compensation of $22.8 million. The $48.8 million represents an increase of $4.5 million in operating expenses compared with the second quarter of 2012, and a decrease of $1.7 million in operating expenses compared with the first quarter of 2013, excluding reorganization-related share-based compensation. The expense increase in the current quarter compared to the second quarter of 2012 was due primarily to increases in asset-based costs associated with our fund and collective products including sub-transfer agent fees and 12b-1 fees, coupled with an investment in personnel related to distribution and infrastructure. The expense decrease when compared to the first quarter of 2013 was primarily attributable to lower incentive compensation costs resulting from higher absolute and relative investment performance in the previous quarter.

Generally Accepted Accounting Principles (“GAAP”)-based operating income was $21.4 million. Operating income, excluding non-cash reorganization-related share-based compensation, was $44.2 million for the quarter, an increase of $7.0 million over the second quarter of 2012 and an increase of $4.4 million from the first quarter of 2013. Operating margin, excluding non-cash reorganization-related share-based compensation expense, was 48% for the second quarter of 2013, compared with 46% for the second quarter of 2012 and 44% for the first quarter of 2013.

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, as defined in the Non-GAAP Financial Measures section below. On this basis, Manning & Napier reported second quarter 2013 economic income of $44.0 million compared with $36.7 million in the second quarter of 2012 and $40.1 million in the first quarter of 2013. Also for the second quarter of 2013, economic net income was $27.2 million, or $0.30 per adjusted share, compared with $22.7 million, or $0.25 per adjusted share, in the second quarter of 2012 and $24.8 million, or $0.28 per adjusted share, in the first quarter of 2013.

On a GAAP basis, net income attributable to the controlling and noncontrolling interests for the second quarter was $18.6 million compared with net income of $9.5 million in the second quarter of 2012 and net income of $16.4 million in the first quarter of 2013. GAAP net income attributable to the common shareholders for the second 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.

Six-months ended June 30, 2013 Financial Review

Manning & Napier reported 2013 year-to-date revenue of $183.2 million, an increase of 10% from revenue of $166.5 million reported in 2012. The increase in 2013 was consistent with changes in average AUM, which increased by 11% 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 $143.7 million, or $99.2 million, excluding non-cash reorganization-related share-based compensation of $44.6 million. The $99.2 million represents an increase of $9.6 million from 2012, due to increases in asset-based costs associated with our fund and collective products, coupled with higher incentive compensation costs resulting from the strong absolute and relative investment performance for the six-months ended June 30, 2013 compared to the prior year. GAAP-based operating income was $39.5 million for the year, and $84.0 million of operating income after excluding non-cash reorganization-related share-based compensation charges. The $84.0 million represents a $7.0 million increase over 2012. Operating margin for 2013 year-to-date, excluding non-cash reorganization-related share-based compensation expense, remained consistent with the prior year at 46%.

Manning & Napier reported 2013 year-to-date economic income of $84.1 million, compared with $76.8 million in 2012. Also for the six-months ended June 30, 2013, economic net income was $51.9 million, or $0.58 per adjusted share, compared with $47.4 million, or $0.53 per adjusted share in 2012.

On a GAAP basis, net income attributable to the controlling and noncontrolling interests for the six-months ended June 30, 2013 was $35.0 million, compared with net income of $43.9 million in 2012. The decrease in the 2013 net income is mainly attributed to an increase in non-cash reorganization-related share-based compensation of $16.8 million when compared to 2012. GAAP net income attributable to the common shareholders for the six-months ended June 30, 2013 was $0.6 million, or $0.04 per basic and diluted share.

Assets Under Management

As of June 30, 2013, AUM was $46.3 billion, a decrease of 4% from the $48.1 billion as of March 31, 2013 and an increase of 9% from the $42.4 billion as of June 30, 2012. As of June 30, 2013, the composition of the Company’s AUM was 54% in separate accounts and 46% in mutual funds and collective investment trusts, which is generally consistent with the composition of 55% and 56% in separate accounts and 45% and 44% in mutual funds and collective investment trusts as of March 31, 2013 and June 30, 2012, respectively.

Since March 31, 2013, AUM decreased by $1.8 billion, including decreases of 5% in separate accounts and 1% in mutual fund collective investment trust AUM. Of the $1.8 billion decrease in AUM from March 31, 2013 to June 30, 2013, 82% or $1.4 billion, of the decrease was driven by net client outflows. The remaining 18% of the decrease was due to market depreciation. As it relates to the Company’s separate accounts, outflows were due to both withdrawals from existing clients and cancellations. The annualized separate account retention rate is 92% for 2013 compared to the 2012 full year retention rate of 95%.

When compared to June 30, 2012, AUM increased by $3.9 billion from $42.4 billion, including an increase of $1.2 billion, or 5%, in separate account AUM and an increase of $2.7 billion, or 14%, in mutual fund and collective investment trust AUM.

Expense Classification Changes

As described in our press release on May 1, 2013, this earnings release reflects the change in presentation of 12b-1 distribution and servicing fees and sub-custodian fees from other operating expenses to distribution, servicing and custody expenses. The Company changed its presentation to more appropriately reflect the nature of these as distribution and asset-based. This reclassification had no impact on previously reported total operating expenses, net income or financial position and does not represent a restatement of any previously published financial results.

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 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 the reorganization-related share-based compensation, which results in non-cash compensation expense reported over the vesting period. Upon the consummation of the initial public offering, the vesting terms related to the ownership of its employees were modified, including the Company’s named executive officers, other than William Manning. Such individuals were entitled to 15% of their pre-IPO ownership interests upon the consummation of the offering, and 15% of their pre-IPO ownership interests over the subsequent three years. The remaining ownership interests are subject to performance-based vesting over such three-year period. Such vesting terms will not result in an increase to the number of outstanding shares of the Company’s Class A common stock or the adjusted share count. As a result of such vesting requirements, the Company will recognize non-cash compensation charges through 2014.

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 weighted average adjusted Class A common shares outstanding. The number of weighted average adjusted Class A common shares outstanding for all periods presented is determined by assuming the weighted average exchangeable units of Manning & Napier Group, LLC and unvested Restricted Stock Units (RSUs) 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.
