Calamos Asset Management, Inc. Reports Strong Results
For Fourth Quarter and Full Year 2004

•   Assets under management climbed 59 percent to $38.0 billion at year-end 2004 versus 2003

•   Pro forma diluted earnings per share were 25 cents for the fourth quarter of 2004 and nearly doubled for 2004 versus 2003, to 79 cents per share

•   Net income was $4.0 million for the two months from the initial public offering (IPO) closing date through year-end

•   Mutual fund net purchases were $9.8 billion, a 49 percent increase over 2003

     NAPERVILLE, Ill., Jan. 31, 2005 – Calamos Asset Management, Inc. (Nasdaq: CLMS) reported strong results for the fourth quarter and full year 2004, led by a 59 percent increase in assets under management at the end of 2004 versus 2003.

     The company had $38.0 billion in assets under management at Dec. 31, 2004, a 14 percent increase from $33.2 billion at Sept. 30, 2004. This asset growth contributed to a 71 percent increase in revenues for the fourth quarter of 2004 versus the same period of 2003, to $91.4 million. The largest component of revenues, investment management fees, climbed 76 percent to $62.2 million for the fourth quarter of 2004 as compared with the year-earlier period.

     Operating income improved 71 percent to $40.6 million for the fourth quarter of 2004 versus the same period of 2003, reflecting higher revenues. Operating margin was 44.4 percent for the 2004 quarter. The company reported $4.0 million in net income from Nov. 2 through Dec. 31, 2004, reflecting its performance after the closing of its initial public offering (IPO). Management believes that pro forma results provide a more meaningful basis for period-to-period comparisons of the company’s results. These pro forma results give effect to the company’s 2004 reorganization, including its IPO, as if it had occurred at the beginning of each period presented.^{1, 2, 3} In addition, pro forma diluted earnings per share reflect the effect of exchanging all membership interests in Calamos Holdings LLC not held by the company for Class A shares of the company. For the fourth quarter of 2004, pro forma diluted earnings per share rose 79 percent to 25 cents, versus 14 cents of pro forma diluted earnings per share for the year-earlier period.

     “As of year-end 2004, 97 percent of our open-end rated fund assets had an overall rating of four or five stars from Morningstar. We believe our solid portfolio performance led to strong net inflows this past quarter,” said John P. Calamos, Sr., chairman and chief executive officer.

Notes to Unaudited Consolidated Condensed Statements of Income

The unaudited condensed consolidated pro forma statements of income for Calamos Asset Management, Inc. and Calamos Family Partners, Inc. for the years ended Dec. 31, 2004 and 2003 and for the three months ended Dec. 31, 2004 and 2003 give effect to the reorganization described in the company’s Registration Statement on Form S-1 (File No. 333-117847) filed with the U.S. Securities and Exchange Commission. The reorganization includes (1) the Real Estate Distribution, whereby Calamos Family Partners, Inc. (formerly known as Calamos Holdings Inc.), distributed its interest in all of its owned real estate assets to its stockholders, who contributed those assets to a new limited liability company; (2) the Formation Transaction, whereby on Oct. 15, 2004, Calamos Family Partners, Inc. contributed all of its assets and liabilities, including all equity interests in its wholly owned subsidiaries, to Calamos Holdings LLC in exchange for 96,800,000 of the membership units of Calamos Holdings LLC; and (3) the consummation of the company’s IPO and use of the net proceeds to acquire membership units in Calamos Holdings LLC. The pro forma statements give effect to the reorganization as if it had occurred at the beginning of each period presented. The most significant pro forma adjustments relate to the minority interest of Calamos Family Partners, Inc. and to income taxes, as Calamos Family Partners, Inc. historically operated as an S corporation. Management believes that pro forma results provide a more meaningful basis for period-to-period comparisons of the company’s results. For more information, see the company’s Registration Statement on Form S-1.

On Nov. 2, 2004, the company became the sole manager of Calamos Holdings LLC and is now conducting the business previously conducted by Calamos Family Partners, Inc. Accordingly, reported results for the periods from Jan. 1, 2004 through Nov. 1, 2004 and Oct. 1, 2004 through Nov. 1, 2004 reflect the operations for Calamos Family Partners, Inc. and its subsidiaries. Reported results for the period from Nov. 2, 2004 through Dec. 31, 2004 reflect the results of operations for Calamos Asset Management, Inc.

1   Represents an adjustment to increase Calamos Asset Management, Inc.’s minority interest allocation to 77.0 percent. Minority interest was determined by multiplying the combined income before minority interest and taxes by Calamos Family Partners, Inc.’s and John P. Calamos, Sr.’s 77.0 percent aggregate ownership. The minority interest adjustment is presented based on the combined income for the periods presented.

2   Reflects the impact of federal and state income taxes on the income allocated from Calamos Holdings LLC to Calamos Asset Management, Inc. Historically, Calamos Family Partners, Inc. operated as an “S” corporation and was not subject to U.S. federal and certain state income taxes, but was subject to Illinois replacement taxes. The amount of pro forma adjustment was determined by eliminating the Illinois replacement tax and applying the combined projected federal corporate income tax rate and applicable state tax rates to income before income taxes.

3   Represents the adjustment related to the Real Estate Distribution based on actual amounts recorded during the periods presented.

4   Represents 23,000,000 shares of Class A common stock, which represents 23.0 percent of the outstanding shares after the offering. In addition to shares of Class A common stock, there are 100 shares of Class B common stock outstanding.

5   Diluted shares outstanding for each period presented represent our weighted average Class A common stock after giving effect to the offering as of the beginning of each period presented. The diluted shares outstanding are calculated: (a) including the effect of outstanding restricted stock unit and option awards and (b) assuming Calamos Family Partners, Inc. and John P. Calamos, Sr. exchanged all of their membership units in Calamos Holdings LLC for, and converted all outstanding shares of our Class B common stock into, shares of our Class A common stock, in each case on a one-for-one basis. In calculating diluted earnings per share an effective tax rate of 39.89 percent was applied to income before minority interest and income taxes.

6   Gives effect to the recharacterization of compensation in the form of equity distributions to owners in the amount of $0.4 million and $1.6 million for the three months ended and twelve months ended December 31, 2004, respectively.

7   Includes $3.7 million of investment income, less: $1.3 million of interest expense and $1.3 million of minority interest related to the consolidation of the Calamos Equity Opportunities Fund L.P. for the period November 2, 2004 to December 31, 2004.
