Three and Nine Months ended September 30, 2004 and 2003
(unaudited)

(1) Organization and Description of Business

     Calamos Asset Management, Inc., together with its subsidiaries (CAM), completed an initial public offering of its Class A common stock on November 2, 2004. On October 15, 2004, Calamos Family Partners, Inc. (formerly known as Calamos Holdings Inc.), (CFP) contributed all of its assets and liabilities, including all equity interests in its wholly-owned subsidiaries, to Calamos Holdings LLC (Holdings) in exchange for 96,800,000 of the membership units of Holdings. On November 2, 2004, CAM applied the net proceeds of its initial public offering to acquire membership units in Holdings and became the sole manager of Holdings. As the sole manager of Holdings, CAM is conducting the business previously conducted by CFP. For more information regarding the initial public offering and the reorganization undertaken in connection therewith (the Reorganization), see CAM’s Registration Statement on Form S-1 (File No. 333-117847) (the Registration Statement) filed with the Securities and Exchange Commission (SEC).

     In these notes to the consolidated financial statements, unless the context otherwise requires, references to “the Company” refer to (1) CFP, its consolidated subsidiaries and their predecessor companies before consummation of the Reorganization, and (2) CAM and its consolidated subsidiaries, including Holdings and the subsidiaries of Holdings, after consummation of the Reorganization. Unless the context otherwise requires:

     The consolidated financial statements included in this report reflect the operations of CFP and its wholly-owned subsidiaries: CAL, CFS, CPM and CPL, prior to the consummation of the Reorganization.

     CAL, an investment adviser registered with the SEC under the Investment Adviser’s Act of 1940, serves as an investment adviser to individual and institutional investors. CAL also provides investment management services to the Calamos Family of Funds (the Funds) and to Calamos Convertible Opportunities and Income Fund, Calamos Convertible and High Income Fund and the Calamos Strategic Total Return Fund (the Closed-end Funds), closed-end funds listed on the New York Stock Exchange.

     CPL is an investment adviser that provides investment management services primarily to alternative investment products.

-6-

     CFS, a broker-dealer registered with the SEC under the Securities Exchange Act of 1934, is (1) the sole distributor of the Funds, (2) an introducing broker-dealer in the purchase and sale of securities and security options, and (3) an introducing broker-dealer in the purchase and sale of securities and security options for the Funds.

     CPM provides real estate investment services. Before consummation of the Reorganization, CPM provided property management services primarily for properties owned by CFP.

(2) Summary of Accounting Policies

   Unaudited Interim Financial Statements

     The interim financial statements as of September 30, 2004 and for the three and nine months ending September 30, 2003 and September 30, 2004 are unaudited. In the opinion of management, such information contains all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the financial condition and results of operations. The results for the interim periods ended September 30 are not necessarily indicative of the results to be obtained for a full fiscal year. As a “C” corporation, CAM will be subject to taxes that apply to “C” corporations that are not reflected in these financial statements. In addition, CAM’s employee compensation and benefit expense as well as certain other operating expenses will differ from CFP’s historical expenses as a result of CAM’s public company status. These financial statements should be read in conjunction with the consolidated financial statements included in the Registration Statement.

   Principles of Consolidation

     The consolidated financial statements included in this report present the financial statements of CFP and its four wholly-owned subsidiaries prior to the Reorganization, and its majority interest in Calamos Hedge Fund, L.P. for the Statement of Financial Condition dated December 31, 2003. All significant intercompany balances and transactions have been eliminated in consolidation.

   Cash and Cash Equivalents

     All highly liquid financial instruments with maturities of three months or less from date of purchase, consisting primarily of investments in money market funds, commercial paper and U.S. government securities, are classified as cash equivalents in the Company’s financial statements.

   Receivables from Customers

     Receivables from customers represent balances arising from contractual investment advisory services provided to separate account customers. During each of the periods presented, bad debt expense and allowance for doubtful accounts were insignificant.

  Investment Securities

     The Company carries its investments at fair value for both trading securities and available-for-sale securities. For a substantial majority of the Company’s investments, fair values are determined based upon market prices. If quoted market prices are not available, the Company uses matrix, model or other similar pricing methods to determine fair value. For the periods presented, non-readily marketable securities represent less than one percent of all investment securities. The Company records investment securities on a trade date basis.

     Because CFS is a registered broker-dealer, the Company is required to classify securities owned by CFS as trading securities. The Company also classifies securities held by Calamos Hedge Fund, L.P. as trading securities. Unrealized gains and losses on trading securities and on partnership units are included in net investment gain (loss) in the statement of income for all periods presented.

     The Company records all securities owned by CAL and CPM as available-for-sale under SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities, as the company does not intend to sell these securities in the near term. Unrealized gains and losses on available-for-sale securities are excluded from earnings and are reported as a separate

-7-

component of stockholders’ equity until realized. Realized gains and losses from the sale of available-for-sale securities are determined on a specific identification basis.

     On a quarterly basis, the Company conducts regular reviews to assess whether other-than-temporary impairment exists. Changing economic conditions, global changes, regional changes, or changes related to specific issuers or industries, could adversely affect these values.

   Property and Equipment

     Property and equipment are recorded at cost less accumulated depreciation. Depreciation is provided on a straight-line basis over the estimated useful lives of the assets, ranging from 3 years to 39 years. Leasehold improvements are amortized over the shorter of their estimated useful lives or the remaining term of the lease.

   Debt Issue Costs

     Deferred debt issuance costs are included in other assets in accordance with APB 21, Interest on Receivables and Payables and amortized on a straight-line basis over the related term of the debt. In accordance with EITF 95-13, Classification of Debt Issue Costs in the Statement of Cash Flows, the deferred costs are classified as a financing activity in the statement of cash flows.

   Equity Incentive Plan

     The Company established a long-term equity appreciation unit plan (EAU Plan) for select individuals of the Company. The Company accounted for the EAU Plan using the accounting methods prescribed by Financial Accounting Standards Board Financial Interpretation No. 28, Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans, an interpretation of APB Opinions No. 15 and 25 (FIN 28), and its related interpretations. In accordance with FIN 28, compensation expense was accrued over the periods in which employees perform services. As such, changes in the aggregate unit value, multiplied by the ratio of actual to total number of service periods in the vesting period were recorded as an increase or decrease to expense in the current period.

   Revenue Recognition

     The Company earns revenue by providing investment management services to open-end and closed-end mutual funds and to separate accounts. This revenue is earned pursuant to the terms of the underlying advisory contract and is based on a contractual investment advisory fee applied to the assets in each portfolio. Any fees collected in advance are deferred and recognized over the period earned. Performance-based advisory fees earned from certain separate accounts are recognized annually upon completion of the contract year and based upon either (1) the positive difference between the investment returns on a client’s portfolio compared to a benchmark index or (2) the absolute percentage of gain in the client’s account.

     Distribution and underwriting fees consist primarily of Rule 12b-1 distribution and/or service fees from the Funds, contingent deferred sales charges (CDSC) on the redemption of fund shares and sales charges that are primarily earned on the distribution of mutual fund shares. 12b-1 fees are accrued monthly as services are performed and are based on the average daily assets of the funds. CDSC fees are recorded on a trade date basis when earned, and sales charges are recorded on the settlement date. The use of settlement date rather than trade date does not have a material effect on the Company’s financial statements.

     Investment and other income includes investment gains (losses), interest and dividend income, and gain on sale of real estate. Dividend and interest income are recognized when earned.

   Deferred Sales Commissions

     Deferred sales commissions are commissions advanced by the Company on the sale of Class B and Class C shares of the Funds. Deferred commissions are amortized on a straight-line basis over the period in which 12b-1 fees are received. Because 12b-1 fees cease upon redemption of shares, amortization expense is accelerated when shares are redeemed resulting in the reduction of the deferred acquisition cost asset. These redemptions result in an amortization period not to exceed 12 months for Class C shares and 96 months (8 years) for Class B shares.

-8-

     The Company evaluates the carrying value of its deferred sales commissions on a quarterly basis. In its impairment analysis, the Company compares the carrying value of the deferred sales commission asset to the undiscounted cash flow expected to be generated by the asset over its remaining useful life to determine whether impairment has occurred. If the carrying value of the asset exceeds the undiscounted cash flow, the asset is written down to fair value based on discounted cash flows. Impairment adjustments are recognized in the statement of income as a component of amortization of deferred sales commissions. As of each reporting period presented, the Company determined that no impairment of the deferred commission asset existed.

   Income Taxes

     During the periods presented, the Company had elected to be taxed as an “S” corporation under the Internal Revenue Code. Therefore, the income and expenses of the Company were included in the income tax returns of the Company’s stockholders. The Company was subject to Illinois replacement tax and other state income taxes. Replacement taxes are recorded as income taxes in the consolidated statement of income.

   Investments in Partnerships

     The Company has an interest in Calamos Multi-Strategy, L.P. (Multi-Strategy) which is accounted for using the equity method and is carried at the net asset value of the partnership units held by the Company.

   Earnings per Share

     Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of shares of common stock outstanding during each year. Shares issued during the year are weighted for the portion of the year that they were outstanding. Diluted earnings per share is equivalent to basic earnings per share because there are no common stock equivalents outstanding during any period presented.

   Use of Estimates in the Preparation of Financial Statements

     Management of the Company has made a number of estimates and assumptions relating to the reporting of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities to prepare these consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. Actual results could differ from those estimates.

(3) Earnings Per Share

     Earnings per share is presented on the Company’s historical basis of 3,953 Class A Voting Common Stock shares and 16,047 Class B Non-voting Common Stock shares. In addition, we have provided earnings per share for the periods ending September 30, 2004, based upon 96,800,000 outstanding membership units of Holdings after giving effect to the Reorganization.

(4) Recently Issued Accounting Pronouncements

     In January 2003, the Financial Accounting Standards Board (FASB) issued Interpretation (FIN) No. 46, Consolidation of Variable Interest Entities (FIN 46), which establishes guidance for consolidation of variable interest entities that function to support the activities of the primary beneficiary. FIN 46 requires a variable interest entity to be consolidated by a company if that company is subject to a majority of the risk of loss from the variable interest entity’s activities or is entitled to receive a majority of the entity’s residual returns. In general, a variable interest entity is a corporation, partnership, trust or any other legal structure used for business purposes that either (a) does not have equity investors with voting rights, or (b) has equity investors that do not provide sufficient financial resources for the entity to support its activities. FIN 46 also requires various disclosures about variable interest entities that a company is not required to consolidate but in which it has a significant variable interest.

     In December 2003, the FASB further revised FIN 46 through FIN No. 46R, Consolidation of Variable Interest Entities (FIN 46R). FIN 46R changes the effective date of FIN 46 for certain entities and makes other significant changes to FIN 46 based on implementation issues that arose during 2003. Application of FIN 46R is required for period ending after December 15, 2003 for all interests in special purpose entities and for period ending after March 15, 2004, for interest in other entities.

-9-

     In assessing if Multi-Strategy is a variable interest entity (VIE), the criteria in paragraph 5 of FIN 46R must be evaluated. In general terms, FIN 46R indicates: if a) the total equity investment at risk is not sufficient for an entity to finance it activities, b) if the group of equity investors of an entity lacks certain characteristics of a controlling financial interest, or c) the voting rights of the equity investors are not proportionate to their returns and substantially all of the entity’s activities either involve or are conducted on behalf of one investor, that entity is considered a VIE, and is subject to consolidation according to the provisions of FIN 46R. The Company determined that such criteria in paragraph 5 of FIN 46R have not been met and Multi-Strategy is therefore not considered a VIE. Accordingly, the Company has determined that Multi-Strategy is a voting interest entity. The Company accounts for its investment in Calamos Multi-Strategy L.P. in accordance with SOP 78-9. Consistent with others in the industry, the Company has historically relied primarily on redemption rights of the limited partners to meet the “important rights” requirement of SOP 78-9. In light of current accounting developments regarding what constitutes “important rights” (including open EITF Issue 04-5 — Investor’s Accounting for an Investment in a Limited Partnership When the Investor is the Sole General Partner and the Limited Partners Have Certain Rights), the Company amended its limited partnership agreements in 2004 to incorporate additional rights, namely to replace the general partner by a simple majority vote of the limited partners. These amendments allow the Company to continue to account for its general partnership interests in the Multi-Strategy on the equity method of accounting and not consolidate it into its results.

(5) Subsequent Events

     As of September 30, 2004, the Company’s business was conducted by CFP, which is wholly-owned by members of the Calamos family and Calamos family trusts. On October 15, 2004, CFP contributed all of its assets and liabilities, including all of the equity interests in its wholly-owned subsidiaries, to Holdings in exchange for 100% of the membership units in Holdings. This transaction established Holdings as the owner and operator of the business conducted by CFP and its subsidiaries.

     On November 2, 2004, CAM closed its initial public offering of 20.0 million shares of common stock at $18 per share and received proceeds, net of the underwriting discount, of $335.7 million. On November 8, 2004, CAM sold an additional 3.0 million shares of common stock pursuant to the exercise of the underwriters’ over-allotment option and received proceeds, net of the underwriting discount, of $50.4 million. CAM used $50.0 million of the proceeds to purchase 3.0 million newly issued membership units directly from Holdings and $332.6 to purchase 20.0 million membership units ($3.0 million of which were purchased in connection with the over-allotment option) in Holdings from CFP. In connection with its initial acquisition of membership units, CAM became the sole manager of Holdings and is conducting the business previously conducted by CFP and its subsidiaries.

     As sole manager of Holdings, CAM operates and controls all of the business and affairs of Holdings and consolidates the financial results of Holdings. In light of Calamos Family Partners, Inc.’s and John P. Calamos, Sr.’s 77.0% ownership interest in Holdings (the Calamos Family Interests), the Company will reflect such ownership interest as a minority interest in its statement of financial condition and statement of income. Net profits or losses and distributions of Holdings are allocated and made to its members pro rata in accordance with the percentages of their respective equity interests. Accordingly, net profits or losses of Holdings are currently allocated, and distributions of Holdings are made, 23.0% to CAM and 77.0% to the Calamos Family Interests. The Company’s historical results will be those of CFP, as its predecessor company. As a result, the Company’s net income, after excluding the Calamos Family Interests, will represent 23.0% of Holdings’ net income, and similarly, outstanding shares of CAM’s Class A common stock will represent 23.0% of the outstanding membership units of Holdings.

     After the pricing of the initial public offering, the Company granted awards of 1,356,137 restricted stock units (RSUs) with an aggregate value of $24.4 million and 727,728 options with an aggregate exercise price of $13.1 million to certain employees pursuant to the Calamos Asset Management, Inc. Incentive Compensation Plan. Certain of these awards replaced all outstanding Equity Appreciation Unit (EAU) awards previously made under the Calamos Family Partners’ Equity Appreciation Units Plan, which was subsequently terminated. The Company will record compensation expense of $3.7 million during the fourth quarter relating to the change in value of the EAUs. The RSUs and option awards are subject to various vesting schedules and will fully vested within six years of the grant date.

     In October 2004, the Company entered into a lease with 2020 Calamos Court LLC, an entity wholly-owned by the shareholders of CFP, with respect to the new corporate headquarters being constructed for its occupancy. The lease was assigned by CFP to Holdings as part of the Reorganization. The term of the lease, and rent under the lease, will commence on the first day of the first month after which Holdings receives possession of the leased premises, which is expected to be in mid-2005, and ends on May 31, 2025. Monthly base rent initially will be $237,183 through May 1, 2006 and will increase by 3% annually, beginning June 1, 2006, for the remaining term of the lease. Minimum base rent payments over the life of the lease will be $76,478,460. In general, Holdings may not terminate the lease unless a casualty, condemnation or material temporary taking affects all or a substantial portion of the leased premises.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

     In the following sections of this report, unless the context otherwise requires, references to “we,” “us,” “our” and “our company” refer to (1) Calamos Family Partners, Inc. (formerly known as Calamos Holdings, Inc.), a Delaware corporation, its subsidiaries and their predecessor companies before consummation of the reorganization undertaken in connection with our initial public offering, which we refer to as the “Reorganization,” and (2) Calamos Asset Management, Inc., a Delaware corporation, and its consolidated subsidiaries, including Calamos Holdings LLC and the subsidiaries of Calamos Holdings LLC, after consummation of the Reorganization. Unless the context otherwise requires:

General

     We provide investment advisory services through our subsidiaries to institutions and individuals, managing $33.2 billion in client assets at September 30, 2004. Our operating results fluctuate primarily due to changes in the total value and composition of our assets under management which are, and will continue to be, significantly influenced by purchases and redemptions of shares of open-end funds and other investment products as well as fluctuations in financial markets around the world that result in appreciation or depreciation of assets under management. The value and composition of our assets under management and our ability to continue to attract clients also depends on a variety of factors including the education of our clients about our investment philosophy, the delivery of best-in-class service, the relative investment performance of our investment products as compared to competing offerings, the competitive conditions in the mutual fund, asset management and broader financial services sectors, investor sentiment and confidence, and our decision to close strategies when deemed in the best interests of our clients.

     We market our investment strategies to our clients through a variety of products designed to suit their individual investment needs. We currently offer the following six types of mutual fund and separate account investment products:

-11-

     The following table details our assets under management at September 30, 2003 and 2004.

     Our revenues are substantially comprised of investment management fees earned under contracts with the mutual funds and separate accounts managed by our subsidiaries. Our revenues are also comprised of distribution and underwriting fees, including asset based distribution and/or service fees received pursuant to Rule 12b-1 plans. Investment management fees and distribution and underwriting fees may fluctuate based on a number of factors, including the total value of our assets under management, market appreciation or depreciation, and the level of net purchases and redemptions, which represent the sum of new client assets, additional funding from existing clients, withdrawals of assets from and termination of client accounts and purchases and redemptions of mutual fund shares. The mix of assets under management among our investment products also has an impact on our revenues, as some products carry different fees than others.

     Our largest operating expense is employee compensation and benefits expense, which includes salaries, incentive compensation and related benefits costs. Expenses related to the distribution of mutual funds, including rule 12b-1 payments and amortization of deferred sales commissions for open-end mutual funds, are also significant. Operating expenses may fluctuate due to a number of factors, including variations in staffing and compensation, changes in distribution expense as a result of fluctuations in mutual fund sales and market appreciation or depreciation, and depreciation and amortization relating to capital expenditures incurred to maintain and enhance our administrative and operating services infrastructure.

Reorganization and Holding Company Structure

     As of September 30, 2004, our business was conducted by Calamos Family Partners, Inc. (formerly known as Calamos Holdings, Inc.), which is wholly-owned by members of the Calamos family and Calamos family trusts. On October 15, 2004, Calamos Family Partners, Inc. contributed all of its assets and liabilities, including all of the equity interests in its wholly-owned subsidiaries, to Calamos Holdings LLC in exchange for 100% of the membership units in Calamos Holdings LLC. This transaction established Calamos Holdings LLC as the owner and operator of the business conducted by Calamos Family Partners, Inc. and its subsidiaries.

     On November 2, 2004, we closed our initial public offering of 20.0 million shares of Class A common stock and received proceeds, net of the underwriting discount, of $335.7 million. On November 8, 2004, we sold an additional 3.0 million shares of common stock pursuant to the exercise of the underwriters’ over-allotment option and received proceeds, net of the underwriting discount, of $50.4 million. We used $50 million of the proceeds to purchase 3.0 million newly issued membership units directly from Calamos Holdings LLC and $332.6 to purchase 20.0 million membership units ($3.0 million of

-12-

which were purchased in connection with the over-allotment option) in Calamos Holdings LLC from Calamos Family Partners, Inc. In connection with our initial acquisition of membership units, we became the sole manager of Calamos Holdings LLC and are conducting the business previously conducted by Calamos Family Partners, Inc. and its subsidiaries.

     As sole manager of Holdings, we operate and control all of the business and affairs of Calamos Holdings LLC and consolidate the financial results of Calamos Holdings LLC. In light of Calamos Family Partners, Inc.’s and John P. Calamos, Sr.’s 77.0% ownership interest in Calamos Holdings LLC, we will reflect such ownership interest as a minority interest in our statement of financial condition and statement of income. Net profits or losses and distributions of Calamos Holdings LLC are allocated and made to its members pro rata in accordance with the percentages of their respective equity interests. Accordingly, net profits or losses of Calamos Holdings LLC are currently allocated, and distributions of Calamos Holdings LLC are made, 23.0% to us and 77.0% to Calamos Family Partners, Inc. and John P. Calamos, Sr. in the aggregate. Our historical results will be those of Calamos Family Partners, Inc., as our predecessor company. As a result, our net income, after excluding the minority interest of Calamos Family Partners, Inc. and John P. Calamos, Sr., will represent 23.0% of Calamos Holdings LLC’s net income, and similarly, outstanding shares of our Class A common stock will represent 23.0% of the outstanding membership units of Calamos Holdings LLC.

Operating Results

     Three Months Ended September 30, 2004 Compared to Three Months Ended September 30, 2003

     Assets Under Management

     Assets under management were $33.2 billion at September 30, 2004, an increase of $13.0 billion, or 65%, from $20.2 billion at September 30, 2003. At September 30, 2004, our assets under management consisted of 69% mutual funds and 31% separate accounts, as compared to 59% mutual funds and 41% separate accounts at September 30, 2003.

     Mutual fund net purchases were $1.3 billion for the three months ended September 30, 2004, a decrease of $0.4 billion, or 26%, from $1.7 billion for the prior year period. Open-end mutual fund purchases were $1.2 billion for the three months ended September 30, 2004, unchanged from the prior year period. The period over period decrease was mainly attributable to $0.5 billion of closed-end fund assets added in July 2003 which did not occur in the three months ended September 30, 2004. Our ability to consummate closed-end fund offerings is dependent on market demand causing our net purchases of closed-end funds to vary period to period. We intend to monitor the market and, consistent with our business strategy, pursue opportunities as they present themselves. Separate account net purchases were $317.3 million for the three months ended September 30, 2004,

-13-

an increase of $172.4 million, from $144.9 million for the prior year period. Although our convertible strategy was closed to new accounts in mid-2003, sales of equity separate accounts resulted in the overall increase in net purchases.

  Revenues

     Total revenues were $81.2 million for the three months ended September 30, 2004, an increase of $36.6 million, or 82%, from $44.6 million for the three months ended September 30, 2003. The increase was due to increases in both investment management fees and distribution and underwriting fees.

     Investment management fees were $55.8 million for the three months ended September 30, 2004, an increase of $25.8 million, or 86%, from $30.0 million for the prior year period as a result of a $12.9 billion increase in average assets under management. The overall growth in investment management fees was due primarily to an increase in mutual fund investment management fees, which increased to $43.4 million for the three months ended September 30, 2004 from $20.3 million for the prior year period. Open-end fund investment management fees increased to $31.3 million for the three months ended September 30, 2004 from $17.0 million for the prior year period as a result of an increase in open-end fund average assets under management of $7.7 billion. Closed-end fund investment management fees increased to $12.1 million for the three months ended September 30, 2004 from $3.3 million for the prior year period as a result of an increase in closed-end fund average assets under management of $3.6 billion. Investment management fees as a percentage of average assets under management increased to an annualized rate of 0.70% for the three months ending September 30, 2004 from an annualized rate of 0.63% for the prior year period as mutual fund assets under management, which generally carry higher investment management fees than separate accounts, increased as a percentage of total assets under management.

     Distribution and underwriting fees were $24.8 million for the three months ended September 30, 2004, an increase of $10.2 million, or 70%, from $14.6 million for the prior year period primarily due to an increase in sales of open-end funds and an $11.3 billion increase in average open-end mutual fund assets under management.

     Other revenues were $0.6 million for the three months ended September 30, 2004 comprised primarily of $0.6 million of portfolio accounting fees earned from mutual funds based on an agreement beginning April 1, 2004.

  Operating Expenses

      Operating expenses were $45.8 million for the three months ended September 30, 2004, an increase of $21.5 million, or 89%, from $24.3 million for the three months ended September 30, 2003. The increase was mainly due to increases in employee compensation and benefits and distribution expenses.

     Employee compensation and benefits increased by $8.6 million primarily due to increased salary and benefits expense of $2.5 million and incentive compensation expense of $4.5 million. We expect our employee compensation and benefits

-14-

expenses to increase as we expand our alternative investment business. Distribution expense increased by $6.7 million, or 108%, primarily due to growth of average open-end fund assets under management, as well as the aging of Class C shares of our open-end funds. Class C share assets do not generate distribution expense in the first year following their sale because we retain the Rule 12b-1 fees during that first year to offset the upfront commissions that we pay. However, Class C share assets do generate a distribution expense in subsequent years as we pay the Rule 12b-1 fees to the selling firms. We expect distribution expense to increase to the extent mutual funds sales and assets under management continue to grow. Amortization of deferred sales commissions increased by $2.4 million, or 46%, primarily due to the $15.7 million, or 36%, increase in the deferred commission asset resulting from the additional commissions advanced on purchases of Class B and C shares of the open-end funds. Marketing and sales promotion expenses increased by $1.4 million primarily due to an increase of $1.0 million in supplemental compensation payments to third-party selling agents, which we expect to increase to the extent our funds gain assets and further recognition. General and administrative expenses increased by $2.4 million, or 126%, principally due to increased occupancy, travel and recruiting costs of $ 1.6 million as a result our increased staffing levels. As a public company, we expect to incur increased general and administrative expenses such as professional fees, directors and officers insurance and public company compliance costs.

   Other Income (Expense), Net

     Other income (expense), net was a net expense of $1.6 million for the three months ended September 30, 2004 compared to a net expense of $5,000 for the three months ended September 30, 2003. This increase in expense was attributable to an increase in interest expense resulting from our issuance in April 2004 of $150.0 million aggregate principal amount of Senior Unsecured Notes due 2011 with a fixed rate of 5.24%.

   Net Income

     Net income totaled $33.1 million for the three months ended September 30, 2004 as compared to $20.0 million for the three months ended September 30, 2003, an increase of 66%.

   Income Taxes

-15-

     During both three-month periods our business was operated as an “S” corporation. As a result, income taxes during these periods are not indicative of our expected future income taxes. We currently operate as a “C” corporation and as such will be subject to taxes applicable to “C” corporations in the future.

     Nine Months Ended September 30, 2004 Compared to Nine Months Ended September 30, 2003

   Assets Under Management

     Assets under management were $33.2 billion at September 30, 2004, an increase of $13.0 billion, or 65%, from $20.2 billion at September 30, 2003.

     Mutual fund net purchases were $8.1 billion for the nine months ended September 30, 2004, an increase of $3.4 billion, or 74%, from $4.7 billion for the prior year period. The increase in mutual fund net purchases was principally attributable to a closed-end fund offering during the nine months ended September 30, 2004, with $3.3 billion in closed-end fund assets under management added during that period as compared to $1.3 billion added for the nine months ended September 30, 2003. Our ability to consummate closed-end fund offerings is dependent on market demand causing our net purchases of closed-end funds to vary period to period. We intend to monitor the market and, consistent with our business strategy, pursue opportunities as they present themselves. In addition, open-end fund net purchases increased to $4.8 billion for the nine months ended September 30, 2004 from $3.4 billion for the prior year period mainly due to sales of the Calamos Growth Fund and Calamos Growth and Income Fund. Separate account net purchases were $627 million for the nine months ended September 30, 2004, an increase of $171.6 million, from $455.8 million for the prior year period primarily due to purchases of our equity strategies.

   Revenues

     Total revenues were $220.7 million, for the nine months ended September 30, 2004, an increase of $111.8 million, or 103%, from $108.9 million for the nine months ended September 30, 2003. The increase was due to increases in both investment management fees and distribution and underwriting fees. We expect revenues to increase through 2005 as we earn investment management fees on the significant amount of assets under management added over the twelve months ended September 30, 2004.

-16-

     Investment management fees were $148.5 million for the nine months ended September 30, 2004, an increase of $74.9 million, or 102%, from $73.7 million for the prior year period as a result of a $12.9 billion increase in average assets under management. The overall growth in investment management fees was due primarily to an increase in mutual fund investment management fees, which increased to $113.6 million for the nine months ended September 30, 2004 from $46.9 million for the prior year period. Open-end fund investment management fees increased to $86.7 million for the nine months ended September 30, 2004 from $40.6 million for the prior year period as a result of an increase in open-end fund average assets under management of $7.7 billion. Closed-end fund investment management fees increased to $26.9 million for the nine months ended September 30, 2004 from $6.3 million for the prior year period as a result of an increase in closed-end fund average assets under management of $3.0 billion. Separate account investment management fees increased by $8.2 million to $34.9 million on an increase in average assets under management of $1.8 billion to $9.6 billion. Investment management fees as a percentage of average assets under management increased to an annualized rate of 0.68% for the nine months ended September 30, 2004 from an annualized rate of 0.60% for the prior year period as mutual fund assets under management, which generally carry higher investment management fees than separate accounts, increased as a percentage of total assets under management.

     Distribution and underwriting fees were $70.6 million for the nine months ended September 30, 2004, an increase of $35.5 million, or 102%, from $35.0 million for the prior year period primarily due to an increase in sales of the open-end funds and a $7.7 billion increase in average open-end fund assets under management.

     Other revenues were $1.6 million for the nine months ended September 30, 2004 including $1.2 million of portfolio accounting fees earned from our mutual funds.

     Operating Expenses

     Operating expenses were $127.9 million for the nine months ended September 30, 2004, an increase of $63.6 million, or 99%, from $64.3 million for the nine months ended September 30, 2003. The increase was primarily due to increases in employee compensation and benefits expense, distribution expense and a one-time marketing and sales promotion expenses.

     Employee compensation and benefits, increased by 90% to $45.2 million primarily due to increased staffing levels, increased compensation rates, including accrued annual bonuses, and increased costs associated with our equity appreciation unit plan. Distribution expense increased by $20.2 million, or 141%, primarily due to growth of average open-end fund assets under management, as well as the aging of Class C shares of our open-end funds. Class C share assets do not generate distribution expense in the first year following their sale because we retain the Rule 12b-1 fees during that first year to offset the upfront commissions that we pay. However, Class C share assets do generate a distribution expense in subsequent years as we pay the Rule 12b-1 fees to the selling firms. We expect distribution expense to increase to the extent mutual fund sales and assets under management continue to grow. Amortization of deferred sales commissions increased by $8.0 million, or 58%, primarily due to the $15.7 million, or 36%, increase in the deferred commission asset resulting from the additional commissions advanced on purchases of Class B and C shares of the open-end funds. Marketing and sales promotion expenses increased by $9.5 million primarily due to an increase of $9.1 million in supplemental compensation payments to third-party selling agents. This increase is largely attributable to a $6.0 million one-time fee to underwriters in connection with a closed-end fund offering during the period. General and administrative expenses increased by $4.4 million, or 71%, predominantly as a result of increased occupancy, travel, professional and business services of $3.2 million as a result of our increased staffing levels.

-17-

   Other Income (Expense), Net

     Other income (expense), net was a net expense of $1.0 million for the nine months ended September 30, 2004 as compared to a net expense of $41,000 for the nine months ended September 30, 2003. Investment and other income for the nine months endings September 30, 2004 included a gain of approximately $2 million related to the distribution of all of our real estate assets consisting of our existing and future corporate headquarters and related property and equipment. The gain was offset by an increase in interest expense attributable to our issuance in April 2004 of $150.0 million aggregate principal amount of Senior Unsecured Notes due 2011 with a fixed rate of 5.24%.

   Net Income

     Net income totaled $90.3 million for the nine months ended September 30, 2004 as compared to $43.8 million for the nine months ended September 30, 2003, an increase of 106%.

   Income Taxes

     During both nine month-periods our business was operated as an “S” corporation. As a result, income taxes during these periods are not indicative of our expected future income taxes. We currently operate as a “C” corporation and as such will be subject to taxes applicable to “C” corporations in the future.

Liquidity and Capital Resources

     Our working capital requirements historically have been met through cash generated by our operations and bank borrowings, as well as our issuance during 2004 of $150.0 million aggregate principal amount of Senior Unsecured Notes due 2011.

     The following tables summarize key statement of financial condition data relating to our liquidity and capital resources.

-18-

     Net cash provided by operating activities was $93.6 million for the nine months ended September 30, 2004, an increase of $73.4 million from $20.2 million for the nine months ended September 30, 2003 with an increase in net income of $46.4 million being the largest contributor to this increase. We expect that operating cash flows will serve as our primary source of working capital for the near future.

     The payment of deferred sales commissions by us to financial intermediaries who sell Class B and C shares of the open-end funds we manage is a significant use of our operating cash flows. Use of cash for deferred sales commissions increased by $2.5 million to $31.9 million for the nine months ended September 30, 2004 from $29.4 million for the nine months ended September 30, 2003. We expect that the payment of deferred sales commissions will continue to increase in the future to the extent sales of Class B and C shares of open-end funds continue to increase. The amortization of deferred sales commissions will similarly be affected.

     Investing activities consist primarily of investments in products that we sponsor and of the purchase of furniture, fixtures and equipment. Net cash used in investing activities increased to $56.7 million for the nine months ended September 30, 2004 from $5.9 million for the nine months ended September 30, 2003 as a result of investment in products managed by us of $47.2 million and increases in furniture, fixtures and equipment to support our increasing staffing levels. We anticipate increasing the future level of investments in products managed by us and expect to use a portion of our net proceeds from our initial public offering to seed new products, including open-end funds and alternative investments.

     Net cash provided by financing activities was $74.5 million for the nine months ended September 30, 2004 as compared to net cash used in financing activities of $13.1 million for the nine months ended September 30, 2003. The change resulted from the issuance of $150.0 million aggregate principal amount of Senior Unsecured Notes, offset by the repayment of $30.4 million of bank and mortgage debt and a $20.8 million increase in distributions to owners, including distributions for their “S” corporation tax liabilities.

     On April 29, 2004, we issued $150.0 million aggregate principal amount of 5.24% Senior Unsecured Notes due April 29, 2011. We used a portion of those net proceeds to repay and terminate a credit facility of approximately $30.0 million, which we entered into during 2002, primarily to finance our payment of deferred sales commissions with respect to open-end funds. We currently fund the payment of deferred sales commissions from operating cash flows and expect to continue to do so in future periods.

     Our total capital at September 30, 2004 was $234.3 million and was comprised of $84.3 million of stockholder equity and $150.0 million of debt under our Senior Unsecured Notes. We expect that in the future, our cash and liquidity requirements will be met primarily through cash generated by operations.

Critical Accounting Policies and Estimates

     The preparation of our consolidated financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under current circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily available from other sources. We evaluate our estimates on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions.

     Accounting policies are an integral part of our consolidated financial statements. A thorough understanding of these accounting policies is essential when reviewing our reported results of operations and our financial position. Management believes that the critical accounting policies and estimates discussed below involve additional management judgment due to the sensitivity of the methods and assumptions used.

   Deferred Sales Commissions

     Deferred sales commissions are commissions advanced by us on the sale of Class B and Class C shares of the open-end funds. Deferred sales commissions are amortized on a straight-line basis over the period in which 12b-1 fees are received. Because 12b-1 fees cease upon redemption of shares, amortization expense is accelerated when shares are redeemed, resulting in the reduction of the deferred sales commission asset. These redemptions result in an amortization period not to exceed 12 months for Class C shares and 96 months (8 years) for Class B shares.

     We evaluate the carrying value of our deferred sales commissions for impairment purposes on a quarterly basis. Significant assumptions utilized by us to estimate future average assets under management include expected future market performance and redemption rates. Market performance assumptions are selected using expected average market returns based on long-term historical returns for each asset class held within the fund. Future redemption assumptions were determined by using the actual redemption rates that each fund experienced over the prior twenty-four month period. These assumptions are reviewed and updated quarterly, or monthly when events or changes in circumstances occur that could significantly increase the risk of impairment of the asset. Estimates of undiscounted future cash flows and the remaining life of the deferred sales commission asset are made from these assumptions.

     If we determine that the deferred sales commission asset is not recoverable, an impairment condition would exist and a loss would be measured as the amount by which the recorded amount of the asset exceeds its estimated fair value. If the carrying value of the deferred sales commission asset exceeds the undiscounted cash flow, the asset is written down to fair value based on discounted cash flows. Impairment adjustments are recognized in the statement of income as a component of amortization of deferred sales commissions. As of each reporting period presented, we determined that no impairment of the deferred commission asset existed, but due to the volatility of the capital markets and the changes in redemption rates, we are unable to predict whether or when future impairment of the deferred sales commission asset might occur.

Equity Incentive Plan

     We established a long-term equity appreciation unit plan (EAU Plan) for select individuals employed by us. We accounted for the EAU Plan using the accounting methods prescribed by Financial Accounting Standards Board Financial Interpretation No. 28, Accounting for Stock Appreciation Rights and Other Variable Stock Option or Award Plans, an interpretation of APB Opinions No. 15 and 25 (FIN 28), and its related interpretations. In accordance with FIN 28, compensation expense was accrued over the periods in which employees perform services. As such, changes in the aggregate unit value, multiplied by the ratio of actual to total number of service periods in the vesting period were recorded as an increase or decrease to expense in the current period.

     The value of the EAU at the valuation date was derived from an equally weighted calculation based on multiples of assets under management, revenue and EBITDA, defined as net income plus interest expense, income taxes and fixed asset depreciation, excluding amortization of deferred sales commissions. We use industry multiples provided by independent third party sources in computing the values.

Recently Issued Accounting Pronouncements

     In January 2003, the Financial Accounting Standards Board (FASB) issued Interpretation (FIN) No. 46, Consolidation of Variable Interest Entities (FIN 46), which establishes guidance for consolidation of variable interest entities that function to support the activities of the primary beneficiary. FIN 46 requires a variable interest entity to be consolidated by a company if that company is subject to a majority of the risk of loss from the variable interest entity’s activities or is entitled to receive a majority of the entity’s residual returns. An entity that consolidates a variable interest entity is called the primary beneficiary of that entity. In general, a variable interest entity is a corporation, partnership, trust or any other legal structure used for business purposes that either (a) does not have equity investors with voting rights, or (b) has equity investors that do not provide sufficient financial resources for the entity to support its activities. FIN 46 also requires various disclosures about variable interest entities that a company is not required to consolidate but in which it has a significant variable interest.

     In December 2003, the FASB further revised FIN 46 through FIN No. 46R, Consolidation of Variable Interest Entities (FIN 46R). FIN 46R changes the effective date of FIN 46 for certain entities and makes other significant changes to FIN 46 based on implementation issues that arose during 2003. Application of FIN 46R is required for periods ending after December 15, 2003 for all interests in special purpose entities and for periods ending after March 15, 2004 for interest in other entities.

     We have an investment in Calamos Multi-Strategy, L.P., a private investment partnership managed by one of our subsidiaries. In assessing if Calamos Multi-Strategy, L.P. is a variable interest entity (VIE), the criteria in paragraph 5 of FIN 46R must be evaluated. In general terms, FIN 46R indicates: if (a) the total equity investment at risk is not sufficient for an entity to finance it activities, (b) if the group of equity investors of an entity lacks certain characteristics of a controlling financial interest, or (c) the voting rights of the equity investors are not proportionate to their returns and substantially all of the entity’s activities either involve or are conducted on behalf of one investor, that entity is considered a VIE and is subject to consolidation according to the provisions of FIN 46R. Accordingly, we determined that such criteria in paragraph 5 of FIN 46R have not been met and the partnership is therefore not considered a VIE.

     We have determined that Calamos Multi-Strategy, L.P., in which Calamos Financial Services holds a general partnership interest, is a voting interest entity. We account for our investment in Calamos Multi-Strategy, L.P. in accordance with AICPA Statement of Position No. 78-9. Consistent with others in the industry, we have historically relied primarily on redemption rights of the limited partners to meet the “important rights” requirement of SOP 78-9. In light of current accounting developments regarding what constitutes “important rights” (including open EITF Issue 04-5 — Investor’s Accounting for an Investment in a Limited Partnership When the Investor is the Sole General Partner and the Limited Partners Have Certain Rights), we amended our limited partnership agreements in 2004 to incorporate additional rights, namely to replace the general partner by a simple majority vote of the limited partners excluding related parties. These amendments will allow us to continue to account for our general partnership interests in the Calamos Multi-Strategy, L.P. on the equity method of accounting and not consolidate it into our results.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

     Our exposure to market risk is directly related to the role of our subsidiaries as investment advisers for the mutual funds and separate accounts they manage. A significant majority of our revenue, approximately 95% for the nine months ended September 30, 2004, is derived from investment advisory, distribution and portfolio accounting agreements with the mutual funds and separate accounts. Under these agreements, the fees we receive are typically based on the market value of the assets under management. Accordingly, a decline in the prices of securities generally may cause our revenue and income to decline by causing the value of the assets we manage to decrease or by causing our clients to withdraw funds in favor of investments that they perceive as offering greater opportunity or lower risk.

     In addition, a decline in the prices of securities may present market conditions that could preclude us from increasing assets under management and prevent us from realizing higher fee revenue associated with such growth.

     We are also subject to market risk due to a decline in the prices of investment securities. We own investment securities primarily comprised of mutual funds managed by Calamos Advisors. At September 30, 2004, the fair value of these investment securities was $58.7 million. Assuming a 10% increase or decrease in the value of these investments, the fair value would increase or decrease by $5.9 million at September 30, 2004. On April 29, 2004, we issued $150 million of Senior Unsecured Notes due April 29, 2011 to various note purchasers in a private placement. These notes have a fixed interest rate of 5.24%, and consequently, we do not believe that these notes have any interest rate risk. Due to the nature of our business, we believe that we do not face any material credit risk, inflation, interest rate or foreign currency rate risk.

Item 4. Controls and Procedures.

     Our management, including our principal executive and principal financial officers, has evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2004, and has concluded that such disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms.

     Our management, including our principal executive and principal financial officers, has evaluated any changes in our internal control over financial reporting that occurred during the quarterly period ended September 30, 2004, and has concluded that there was no change during the quarterly period ended September 30, 2004 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings.

     In the normal course of business, we may be subject to various legal proceedings from time to time. Currently, there are no legal proceedings pending against us or any of our subsidiaries.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

     (a) In July 2004, upon our incorporation, we issued 100 shares of common stock to Calamos Holdings, Inc. in exchange for $1.00. In connection with our initial public offering, in October 2004 each of those shares of common stock was changed into and reclassified as a share of our Class B common stock. Each share of our Class B common stock is convertible at the option of the holder into one share of our Class A common stock. Any shares of Class B common stock transferred to a person other than a member of the Calamos family or any entity controlled by one or more members of the Calamos family shall automatically convert to shares of our Class A common stock upon such disposition. If the number of outstanding shares of our Class B common stock plus the number of membership units in Calamos Holdings LLC and shares of Class A common stock owned by the holders of the Class B common stock falls below 15% of the total number of outstanding membership units in Calamos Holdings LLC, then all outstanding shares of our Class B common stock shall automatically convert into our Class A common stock.

     (b) The effective date of our registration statement filed on Form S-1 under the Securities Act of 1933 (File No. 333-117847) relating to our initial public offering of shares of Class A common stock was October 27, 2004. A total of 23,000,000 shares of the our Class A common stock were registered, and all shares were sold. The joint bookrunning managers for the offering were Citigroup Global Markets Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated.

     The offering commenced on October 27, 2004 and has been completed. The offering price per share was $18.00 resulting in gross offering proceeds to us of $414,000,000. The underwriting discount was $27,945,000, none of which was paid to our affiliates. We incurred approximately $3.2 million of other expenses in connection with the offering. The net proceeds to us totaled approximately $383.3 million.

Item 3. Defaults Upon Senior Securities.

Item 5. Other Information

UNAUDITED PRO FORMA FINANCIAL INFORMATION

     The following unaudited pro forma condensed consolidated financial statements have been derived by applying pro forma adjustments to our historical consolidated financial statements included in this report.

     The adjustments necessary to fairly present the unaudited pro forma condensed consolidated financial statements are based on available information and assumptions that we believe are reasonable. The unaudited pro forma condensed consolidated statements of income and financial condition are presented for illustrative purposes only and do not purport to represent our consolidated results of operations or financial position that would actually have occurred had the transactions referred to below been consummated on January 1, 2004 for the consolidated statement of income and on September 30, 2004 for the consolidated statement of financial condition, or to project our consolidated results of operations or financial position for any future date or period.

-23-

     The unaudited pro forma condensed consolidated income statement for the nine months ended September 30, 2004 give pro forma effect to the Reorganization, including (1) the “Real Estate Distribution,” by which Calamos Family Partners, 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, Calamos Property Holdings LLC, (2) the “Formation Transaction,” by which Calamos Family Partners, Inc. established Calamos Holdings LLC as a Delaware limited liability company and contributed all of its assets and liabilities, including all equity interests in its wholly-owned subsidiaries, to Calamos Holdings LLC in exchange for all of the membership units of Calamos Holdings LLC and (3) the consummation of our initial public offering and our application of a portion of the net proceeds from the offering to purchase newly issued membership units in Calamos Holdings LLC and the remaining net proceeds to purchase membership units in Calamos Holdings LLC from Calamos Family Partners, Inc., in each case as though such transactions had occurred at the beginning of such periods. The unaudited pro forma consolidated statement of financial condition as of September 30, 2004 gives pro forma effect to the transactions described above as if they had occurred on September 30, 2004, except that it does not give pro forma effect to the Real Estate Distribution, as such distribution occurred on June 30, 2004 and is already reflected in our historical results as of September 30, 2004.

     As a result of the Reorganization, we became the sole manager of Calamos Holdings LLC, and, together with its direct and indirect subsidiaries, are conducting the business formerly conducted by the subsidiaries of Calamos Family Partners, Inc. As sole manager of Calamos Holdings LLC, we operate and control all of the business and affairs of Calamos Holdings LLC and consolidate the financial results of Calamos Holdings LLC with ours. In light of Calamos Family Partners, Inc.’s and John P. Calamos, Sr.’s 77.0% aggregate ownership interest in Calamos Holdings LLC, we reflect such ownership interest as a minority interest in our statement of financial condition and statement of income. Our historical results are those of Calamos Family Partners, Inc., as our predecessor company. As a result, our net income, after excluding Calamos Family Partners, Inc.’s and John P. Calamos, Sr.’s minority interest, represents 23.0% of Calamos Holdings LLC’s net income, and similarly, outstanding shares of our Class A common stock represent 23.0% of the outstanding membership units of Calamos Holdings LLC.

     Read this unaudited pro forma condensed consolidated financial information together with the other information contained in this report, including “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and our unaudited interim consolidated financial statements and the notes thereto.
