Manning & Napier, Inc. Reports First Quarter 2015 Earnings Results

FAIRPORT, NY, April 29, 2015 - Manning & Napier, Inc. (NYSE: MN), (“Manning & Napier” or “the Company”) today reported 2015 first quarter results for the period ended March 31, 2015.

Summary Highlights

Patrick Cunningham, Manning & Napier’s Chief Executive Officer, commented, “Manning & Napier has remained consistent in its investment philosophy for nearly 45 years, but we continually challenge our personnel to improve execution to meet the investment objectives of our clients in an ever-changing environment. As a result, we recently named Ebrahim Busheri as the new Director of Investments, a role he also held at Manning & Napier in the late 1990’s into the early 2000’s. I am excited to have Ebrahim in this role and his leadership and tenacity have already led to structural enhancements. Most notably, we have modified the structure of several of our investment decision-making teams, shifting from larger teams to teams of four senior individuals per core-portfolio. We believe these changes have already sharpened our focus, while maintaining our ability to be nimble, which has been a key contributor to our success in the past. These changes have also allowed us to promote strong performers within our Research team. Continuous improvement is a necessity in our business and I am confident that these enhancements, as well as a continued focus on finding solutions for our clients, will continue to deliver better results for our clients in the months and years to come.”

First Quarter 2015 Financial Review

Manning & Napier reported first quarter 2015 revenue of $90.4 million, a decrease of 8% from revenue of $98.5 million reported in the first quarter of 2014, and a decrease of 8% from revenue of $98.3 million reported in the fourth quarter of 2014. The changes in revenue resulted primarily from changes in average AUM. Average AUM for the quarter was $47.1 billion, an 8% and 5% decrease over average AUM for the first quarter of 2014 and the fourth quarter of 2014, when average AUM was $51.1 billion and $49.5 billion, respectively. Revenue as a percentage of average AUM was 0.78% for the first quarter of 2015, compared to 0.78% and 0.79% for the first quarter of 2014 and fourth quarter of 2014, respectively.

The Company completed the service and performance-based vesting of pre-initial public offering ownership interests in 2014 and as such, no longer records non-cash reorganization-related share based compensation expense. Beginning with the period ending March 31, 2015, economic income is equivalent to income before provision for income taxes. Refer to the Non-GAAP Financial Measures section below for additional details.

Operating expenses for the first quarter 2015 were $52.6 million. The $52.6 million is a decrease of $3.7 million, or 6%, in operating expenses compared with the first quarter of 2014, and a decrease of $2.2 million, or 4%, in operating expenses compared with the fourth quarter of 2014, excluding non-cash reorganization-related share-based compensation for the prior quarters. The expense decrease in the current quarter compared to the first quarter of 2014 was due primarily to lower incentive compensation costs for our analyst team resulting from investment performance during the respective periods. The expense decrease in the current quarter compared to the first quarter and fourth quarter of 2014 was also driven by a decrease in distribution, servicing and custody expenses. As a percentage of revenue, compensation and related costs for the first quarter of 2015 were 30%, compared with 30% for the first quarter of 2014 and 27% for the fourth quarter of 2014. Distribution, servicing and custody expenses for the first quarter of 2015 decreased by $1.6 million, or 9%, compared to the first quarter of 2014, and decreased by $2.0 million, or 11%, compared to the fourth quarter of 2014, while average mutual fund and collective trust AUM decreased by 10% and 8% for the respective periods.

Operating income was $37.8 million for the quarter, a decrease of $4.4 million, or 10%, from the first quarter of 2014 and a decrease of $5.7 million, or 13%, from the fourth quarter of 2014, excluding non-cash reorganization-related share-based compensation for the prior quarters. Operating margin was 42% for the first quarter of 2015, compared with 43% for the first quarter of 2014 and 44% for the fourth quarter of 2014.

Non-operating income was $0.8 million for the quarter, compared to non-operating income of $2.4 million and a loss of $0.2 million reported in the first quarter of 2014 and fourth quarter of 2014, respectively. Non-operating income reported in the first quarter of 2014 was primarily attributable to $2.1 million of income resulting from a decrease in the amounts payable under the tax receivable agreement driven by enacted changes in tax laws during the first quarter of 2014, which reduced expected tax benefits and subsequent payment of such benefits under the tax receivable agreement. Excluding the impact from these tax law changes, the increase in non-operating income is primarily due to the performance on investments held by the Company to provide initial cash seeding for product development purposes.

As defined in the Non-GAAP Financial Measures section below, the Company used economic income for periods prior to the first quarter of 2015 and continues to use economic net income to provide greater clarity regarding the cash earnings of the business. On this basis, Manning & Napier reported first quarter 2015 income before taxes of $38.6 million compared with economic income of $44.7 million in the first quarter of 2014, a 14% decrease, and economic income of $43.3 million in the fourth quarter of 2014, a 11% decrease. Also for the first quarter of 2015, economic net income was $24.3 million, or $0.28 per adjusted share, compared with $27.6 million, or $0.31 per adjusted share, in the first quarter of 2014 and $26.7 million, or $0.30 per adjusted share, in the fourth quarter of 2014.

On a GAAP basis, net income attributable to the controlling and noncontrolling interests for the first quarter of 2015 was $36.1 million, compared with net income of $17.6 million in the first quarter of 2014 and net income of $68.5 million in the fourth quarter of 2014. GAAP net income attributable to the common shareholders for the first quarter of 2015 was $3.3 million, or $0.24 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.

Assets Under Management

As of March 31, 2015, AUM was $45.6 billion, a decrease of 5% from the $47.8 billion as of December 31, 2014 and a decrease of 13% from the $52.2 billion as of March 31, 2014. As of March 31, 2015, the composition of the Company’s AUM was 55% in separate accounts and 45% in mutual funds and collective investment trusts, compared to 53% and 52% in separate accounts and 47% and 48% in mutual funds and collective investment trusts as of December 31, 2014 and March 31, 2014, respectively.

Since December 31, 2014, AUM decreased by $2.2 billion, including decreases of 1% in separate accounts and 9% in mutual funds and collective investment trusts AUM. The $2.2 billion decrease in AUM from December 31, 2014 to March 31, 2015 was attributable to net client outflows of $2.6 billion offset by market appreciation and other changes of $0.4 billion. The net client outflows of $2.6 billion consisted of net client outflows for both the mutual funds and collective investment trusts products and separate accounts of $2.2 billion and $0.4 billion, respectively. The annualized separate account retention rate is 95% for the first quarter of 2015, compared to 92% for the full year 2014.

When compared to March 31, 2014, AUM decreased by $6.6 billion from $52.2 billion, including a decrease of $2.1 billion, or 8%, in separate account AUM and a decrease of $4.5 billion, or 18%, in mutual fund and collective investment trust AUM. The $6.6 billion decrease in AUM from March 31, 2014 to March 31, 2015 was attributable to net client outflows of $6.0 billion, as well as market depreciation and other changes of $0.6 billion. The net client outflows of $6.0 billion consisted of $2.4 billion of net outflows for separate accounts, and $3.6 billion of net outflows for mutual funds and collective investment trusts.

Balance Sheet

As of March 31, 2015, cash and cash equivalents were $80.4 million, compared with $125.0 million as of December 31, 2014. The decrease in cash and cash equivalents during the quarter is primarily due to the purchase and retirement of Class A units of Manning & Napier Group, LLC for approximately $36.3 million in connection with the Company’s annual exchange of units as announced on March 30, 2015.

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 used economic income and continues to use economic net income and economic net income per adjusted share as financial measures to evaluate the profitability and efficiency of the Company’s business. Economic income, economic net income and economic net income per adjusted share are not presented in accordance with GAAP.

Economic income prior to the first quarter of 2015, excluded from income before provision for income taxes the reorganization-related share-based compensation, which resulted 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, other than William Manning, were modified such that 85% of their pre-IPO ownership interests were subject to service and performance-based vesting through 2014. Beginning with the period ending March 31, 2015, economic income is equivalent to 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 37.0% on income before taxes for the first quarter of 2015 and 38.25% on economic income for the first and fourth quarters of 2014, 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 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.
