(PITTSBURGH, Pa., April 27, 2006) — Federated Investors, Inc.

These results include net earnings of $2.8 million or $0.03 per share classified as income from discontinued operations related to the sale of the company’s trade-clearing operation. This sale, to be completed over a series of closings, began in Q1 2006 and is expected to be substantially complete by the end of Q2 2006. Federated’s Q1 2006 results also include a pre-tax charge of $2.0 million or $0.01 net per share for severance expense and $1.3 million pre-tax or $0.01 net per share in stock-based compensation expense resulting from the required adoption of SFAS 123(R). In addition, revenues were reduced by $1.0 million pre-tax or $0.01 net per share from the impact of advisory fee reductions implemented on Jan. 1, 2006.

Federated’s income from continuing operations was $0.43 per diluted share for the quarter ended March 31, 2006 compared with $0.06 per share for the same quarter last year. Income from continuing operations was $46.1 million for Q1 2006 compared to $6.8 million for Q1 2005.

Federated’s total managed assets were $217.5 billion at March 31, 2006, up $38.5 billion or 22 percent from $179.0 billion at March 31, 2005 and up $4.1 billion or 2 percent from the $213.4 billion reported at Dec. 31, 2005. Through its mutual funds and separately managed accounts, Federated managed $53.9 billion in equity and fixed-income assets as of March 31, 2006, a 1 percent increase from $53.2 billion as of March 31, 2005. Average managed assets for Q1 2006 were $217.5 billion, up $38.1 billion or 21 percent from $179.4 billion reported for Q1 2005 and up $7.4 billion or 4 percent from $210.1 billion in average managed assets reported for Q4 2005.

Federated’s board of directors declared a quarterly dividend of $0.18 per share, an increase of 20 percent from $0.15 per share last quarter. The dividend is payable on May 15, 2006 to shareholders of record as of May 8, 2006. During Q1 2006, Federated purchased 632,607 shares of class B common stock for $22.9 million.

Federated’s equity assets were $31.6 billion at March 31, 2006, up $3.3 billion or 12 percent from $28.3 billion at March 31, 2005 and up $1.8 billion or 6 percent from $29.8 billion at Dec. 31, 2005. Federated’s top selling equity mutual funds on a net basis were: Federated Kaufmann Small Cap Fund, Federated Kaufmann Fund, Federated Strategic Value Fund and Federated Muni and Stock Advantage Fund. Federated continued to grow assets through strategic acquisitions in Q1 2006 as Federated Mid-Cap Index Fund acquired $218 million in assets from the Mason Street Index 400 Fund and Federated Kaufmann Fund acquired $158 million in assets from the Wayne Hummer Growth Fund.

Federated’s fixed-income assets were $22.3 billion at March 31, 2006, down $2.6 billion or 10 percent from $24.9 billion at March 31, 2005 and down $0.7 billion or 3 percent from $23.0 billion at Dec. 31, 2005. Federated’s top selling fixed-income mutual funds on a net basis were: Federated Total Return Government Fund, Federated Total Return Bond Fund and Federated Intermediate Government/Corporate Fund.

Money market assets in both funds and separate accounts were $163.6 billion at March 31, 2006, up $37.9 billion or 30 percent from $125.7 billion at March 31, 2005 and up $3.0 billion or 2 percent from $160.6 billion at Dec. 31, 2005. Money market mutual fund assets increased to $146.0 billion at the end of Q1 2006, up 33 percent from $109.9 billion at March 31, 2005 and up slightly from $145.3 billion Dec. 31, 2005.

Financial Summary

For Q1 2006, revenue increased $36.9 million or 18 percent to $238.8 million as compared to $201.9 million for the same quarter last year, primarily due to Federated’s acquisition of Alliance Capital Management L.P.’s cash management business in 2005 and to organic growth in money market assets. Higher equity assets also led to the increase in revenue, partially offset by lower fixed income assets. Revenue for Q1 2006 included the impact of $1.0 million in advisory-fee reductions implemented Jan. 1, 2006 related to the company’s settlement with the New York State Attorney General. For Q1 2006, Federated derived 47 percent of its revenue from money market assets, 38 percent from equity assets, 14 percent from fixed-income assets and 1 percent from other products.

Operating expenses for Q1 2006 of $164.6 million decreased by $8.7 million or 5 percent from $173.3 million for Q1 2005. Marketing and distribution expense was affected primarily by higher expenses related to the Alliance acquisition.

Discontinued operations for Q1 2006 reflects $1.0 million or $0.01 per share of primarily after-tax operating income related to Federated’s trade-clearing operation, which the company began to divest in Q1 2006, and $1.8 million or $0.02 per share for the reversal of a tax-valuation allowance for the portion of Federated’s capital loss carryforwards that will likely be realized as a result of the capital gain expected on the sale of the trade-clearing operation.
