CALAMOS, SR. PHOTO) Dear Shareholder: Thank you for your interest in the Calamos Family of Funds, as we welcome the opportunity to be a part of your long-term financial plan. Inside this semi-annual report you will find performance, sector allocation, holdings and financial highlights for all of Calamos Investment Trust portfolios, including the newest portfolio, the Calamos International Growth Fund. Here at Calamos Investments, we manage all of our funds to seek solid long-term risk-adjusted performance. One of the keys to our investment process is to concentrate not on short-term market fluctuations, but to position our portfolios for where we believe the market is headed, not where it has been. Although our family of funds range from more aggressive to more conservative investment approaches, each portfolio's holding is assessed on its potential downside versus its upside, and then adjusted when necessary in anticipation of our economic and market outlook. Currently, we believe that we are in the middle phase of the economic cycle, and have strived to position each portfolio for a period of slow, but stable growth, generally favoring higher quality, often larger-sized companies. We consider our communications to shareholders to be a critical part of our customer service orientation and urge you to review the quarterly fund reviews and market commentaries for further information regarding our outlook and positioning. Remember that our Web site (www.calamos.com) can provide you with market updates, current fund performance, portfolio information and more. For example, we have recently added a tax center to assist you as tax season approaches. The center includes fund income and capital gain distributions, qualified dividend data, a tax calendar and a guide to tax forms. All data will be updated for 2005 as it becomes available. If you have any questions about your account or investment, you can contact your financial advisor, visit us at www. calamos.com or contact a Calamos Client Service Representative at 800.582.6959 Monday thorough Friday, 8 a.m. to 6 p.m (Central Time). Once again, thank you for your confidence in Calamos Investments and the Calamos Family of Funds. We look forward to being part of your long-term investment plan in the months and years ahead. Sincerely, /s/ JOHN P. CALAMOS, SR. - ------------------------------------- JOHN P. CALAMOS, SR.

Morningstar ratings are for Class A shares; the other classes may have different performance characteristics. For each U.S.-domiciled fund with at least a three year history, Morningstar calculates a Morningstar Rating(TM) based on a Morningstar risk-adjusted return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive five stars, the next 22.5% receive four stars, the next 35% receive three stars, the next 22.5% receive two stars and the bottom 10% receive one star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) 2 SEMIANNUAL REPORT Calamos Growth Fund Calamos Growth Fund AVERAGE ANNUAL TOTAL RETURN+ 10 YEARS OR 1 YEAR 3 YEARS 5 YEARS @SINCE INCEPTION load-adjusted load-adjusted load-adjusted load-adjusted ------------- ------------- ------------- ---------------- CLASS A SHARES - Inception 9/4/90 16.07% 10.57% 19.59% 17.66% 3.18% 2.18% 20.66% 20.07% CLASS B SHARES - Inception 9/11/00 15.21 10.21 18.70 17.99 4.20 3.86 4.30@ 4.13@ CLASS C SHARES - Inception 9/3/96 15.19 14.19 18.70 18.70 2.71 2.71 19.87@ 19.87@ CLASS I SHARES - Inception 9/18/97 16.37 NA 19.89 NA 3.92 NA 17.68@ NA PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE RESULTS.

Morningstar ratings are for Class A shares; the other classes may have different performance characteristics. For each U.S.-domiciled fund with at least a three year history, Morningstar calculates a Morningstar Rating(TM) based on a Morningstar risk-adjusted return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive five stars, the next 22.5% receive four stars, the next 35% receive three stars, the next 22.5% receive two stars and the bottom 10% receive one star.

For each U.S.-domiciled fund with at least a three year history, Morningstar calculates a Morningstar Rating(TM) based on a Morningstar risk-adjusted return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive five stars, the next 22.5% receive four stars, the next 35% receive three stars, the next 22.5% receive two stars and the bottom 10% receive one star.

MORNINGSTAR RATING(TM) * * * * overall among 63 convertible funds A SHARES CCVIX INCEPTION June 21, 1985 As of 09/30/2005, Morningstar rated the Calamos Convertible Fund two stars for three years, four stars for five years and five stars for 10 years out of 63, 56 and 33 convertible funds, respectively. Morningstar ratings are for Class A shares; the other classes may have different performance characteristics. For each U.S.-domiciled fund with at least a three year history, Morningstar calculates a Morningstar Rating(TM) based on a Morningstar risk-adjusted return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive five stars, the next 22.5% receive four stars, the next 35% receive three stars, the next 22.5% receive two stars and the bottom 10% receive one star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) 16 SEMIANNUAL REPORT Calamos Convertible Fund Calamos Convertible Fund AVERAGE ANNUAL TOTAL RETURN+ 10 YEARS OR 1 YEAR 3 YEARS 5 YEARS @SINCE INCEPTION -------------------- --------------------- -------------------- --------------------- load-adjusted load-adjusted load-adjusted load-adjusted ------------- ------------- ------------- ------------- CLASS A SHARES - Inception 6/21/85 8.04% 2.92% 12.94% 11.12% 4.02% 3.02% 11.51% 10.96% CLASS B SHARES - Inception 9/11/00 7.25 2.25 12.09 11.29 5.46 5.13 6.02@ 5.86@ CLASS C SHARES - Inception 7/5/96 7.25 6.25 12.10 12.10 3.40 3.40 10.60@ 10.60@ CLASS I SHARES - Inception 6/25/97 8.27 NA 13.22 NA 4.25 NA 10.09@ NA PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE RESULTS.

MORNINGSTAR RATING(TM) *** overall among 252 conservative allocation funds A SHARES CVSIX INCEPTION September 4, 1990 As of 09/30/2005, Morningstar rated the Calamos Market Neutral Fund two stars for three years, four stars for five years, and four stars for 10 years out of 252, 165 and 66 conservative allocation funds, respectively. Morningstar ratings are for Class A shares; the other classes may have different performance characteristics. For each U.S.-domiciled fund with at least a three year history, Morningstar calculates a Morningstar Rating(TM) based on a Morningstar risk-adjusted return measure that accounts for variation in a fund's monthly performance (including the effects of sales charges, loads and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of funds in each category receive five stars, the next 22.5% receive four stars, the next 35% receive three stars, the next 22.5% receive two stars and the bottom 10% receive one star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) 18 SEMIANNUAL REPORT Calamos Market Neutral Fund Calamos Market Neutral Fund AVERAGE ANNUAL TOTAL RETURN+ 10 YEARS OR 1 YEAR 3 YEARS 5 YEARS @SINCE INCEPTION -------------------- -------------------- -------------------- -------------------- load-adjusted load-adjusted load-adjusted load-adjusted ------------- ------------- ------------- ------------- CLASS A SHARES - Inception 9/4/90 1.76% -3.05% 5.28% 3.58% 5.22% 4.20% 8.55% 8.03% CLASS B SHARES - Inception 9/11/00 1.07 -3.52 4.52 3.67 5.07 4.75 5.23@ 5.08@ CLASS C SHARES - Inception 2/16/00 1.01 0.10 4.50 4.50 4.68 4.68 5.60@ 5.60@ CLASS I SHARES - Inception 5/10/00 2.06 NA 5.57 NA 5.48 NA 6.31@ NA PERFORMANCE DATA QUOTED REPRESENTS PAST PERFORMANCE, WHICH IS NO GUARANTEE OF FUTURE RESULTS. Current performance may be lower or higher than the performance quoted. The principal value and investment return of an investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. Performance of the Market Neutral Fund includes the effects of an overpayment of dividends and/or capital gains distributions to shareholders of certain share classes of the Fund (and a corresponding capital contribution by Calamos Asset Management, Inc., the predecessor to Calamos Advisors LLC), which increased certain return figures. + Average annual total return measures net investment income and capital gain or loss from portfolio investments as an annualized average assuming reinvestment of dividends and capital gains distributions. Performance shown reflects the effects of an expense reimbursement that improved results and was in effect until March 31, 2000. Load-adjusted returns are adjusted for the maximum front-end sales load of 4.75% for Class A shares and returns for Class B and C shares have been adjusted for the contingent deferred sales charge (CDSC).

Calamos Market Neutral Fund SEMIANNUAL REPORT 19 Expense Overview As a shareholder of a mutual fund, you incur two types of costs. You incur: 1) Transaction costs, including sales charges or loads, on purchase payments, or other distributions. 2) Ongoing costs, including management fees, distribution and/or service (12b-1) fees and other fund expenses. The examples in this report are based on an investment of $1,000 made at the beginning of the period and held for the entire period from April 1, 2005 to September 30, 2005. It is intended to help you understand the ongoing cost associated with investing in each mutual fund and to compare these costs with the ongoing costs of investing in other mutual funds. There are two parts of each Fund's chart: ACTUAL In this part of the chart, you'll see the actual expenses you would have on a $1,000 investment made at the beginning of the period and held for the entire period in each fund from April 1, 2005 to September 30, 2005, the period covered by this report. This chart also shows the actual returns, after expenses, you would have earned during that time. This chart can help you estimate your own expenses. For example, if you invested $8,600 in Class A shares of the fund, simply divide $8,600 by $1,000, then multiply that result by the figure in the "Actual Expenses per $1,000" row. (In this example, you would multiply 8.6 by the figure.) HYPOTHETICAL In this part of the chart, you'll see the hypothetical expenses you would have paid on $1,000 investment from April 1, 2005 to September 30, 2005, and the hypothetical returns, after expenses, you would have earned during that time. The Securities and Exchange Commission (SEC) has established the guidelines for this chart, including the 5% annual return before expenses, which is what you'll see in the chart. Note that this chart will not help you determine your own expenses, but will help you compare expenses of the fund you own to the expenses of another fund since the information for that fund should be calculated using the same assumptions. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not include any transactional costs, such as sales charges (loads), redemption fees or exchange fees. Therefore, the second line of the table is useful in comparing ongoing costs only and will not help you determine the relative total costs of owning different funds.

accompanying Notes to Financial Statements 60 SEMIANNUAL REPORT Statements of Changes in Net Assets NOTES TO FINANCIAL STATEMENTS (UNAUDITED) NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION. CALAMOS INVESTMENT TRUST, a Massachusetts business trust organized December 21, 1987 (the "Trust"), consists of nine series, CALAMOS Growth Fund, CALAMOS Blue Chip Fund, CALAMOS Value Fund, CALAMOS International Growth Fund, CALAMOS Global Growth and Income Fund, CALAMOS Growth and Income Fund, CALAMOS High Yield Fund, CALAMOS Convertible Fund, and CALAMOS Market Neutral Fund (the "Funds"). Each fund is registered under the Investment Company Act of 1940 as a diversified, open-end management investment company. The Trust currently offers Class A, Class B, Class C and Class I shares of each of the Funds. The CALAMOS Convertible Fund and CALAMOS Market Neutral Fund are closed to all new investments, subject to the exceptions enumerated in the Prospectus. PORTFOLIO VALUATION. In computing the net asset value of the Funds, portfolio securities that are traded on a securities exchange in the United States, except an option security, are valued at the last reported sale price as of the time of valuation, or lacking any current reported sale at the time of valuation, at the mean between the most recent bid and asked quotations. Each option security traded on a securities exchange in the United States is valued at the last current reported sale price as of the time of valuation if the last current reported sale price falls within the consolidated bid/ask quote for the option security. If the last current reported sale price as of the time of valuation does not fall within the consolidated bid/ask quote for the option security, the security is valued at the mid-point of the consolidated bid/ask quote for the option security. Each security traded in the over-the-counter market and quoted on the NASDAQ National Market System, is valued at the NASDAQ Official Closing Price ("NOCP"), as determined by NASDAQ, or lacking an NOCP, the last current reported sale price as of the time of valuation by NASDAQ, or lacking any current reported sale on NASDAQ at the time of valuation, at the mean between the most recent bid and asked quotations. Each over-the-counter option that is not traded through the Options Clearing Corporation is valued by the counterparty, or if the counterparty's price is not readily available then by using the Black-Scholes method. Each other security traded over-the-counter is valued at the mean between the most recent bid and asked quotations. Short-term securities with maturities of 60 days or less are valued at amortized cost, which approximates market value. When market quotations are not readily available or when the valuation methods mentioned above are not reflective of the fair value of the security, the security is priced at a fair value following procedures and/or guidelines approved by the Board of Trustees, which may include utilizing a systematic fair valuation model provided by an independent pricing system. The Funds' may also use fair value pricing, if the value of a security it holds is, pursuant to Board of Trustees' guidelines, materially affected by events occurring before the Funds' pricing time but after the close of the primary market or exchange on which the security is traded. These procedures may utilize valuations furnished by pricing services approved by the Board of Trustees, which may be based on market transactions for comparable securities and various relationships between securities that are generally recognized by institutional traders, a computerized matrix system, or appraisals derived from information concerning the securities or similar securities received from recognized dealers in those securities. When fair value pricing is employed, the value of the portfolio security used to calculate the Funds' net asset value may differ from quoted or official closing prices. Securities that are principally traded in a foreign market are valued at the last current sale price at the time of valuation or lacking any current or reported sale, at the time of valuation, at the mean between the most recent bid and asked quotations as of the close of the appropriate exchange or other designated time. Trading in securities on European and Far Eastern securities exchanges and over-the-counter markets is normally completed at various times before the close of business on each day on which the New York Stock Exchange ("NYSE") is open. Trading of these securities may not take place on every NYSE business day. In addition, trading may take place in various foreign markets on Saturdays or on other days when the NYSE is not open and on which the Fund's net asset value is not calculated. As stated above, if the market prices are not readily available or are not reflective of the fair value of the security, the security will be priced at a fair value following procedures approved by the Board of Trustees. In light of the judgment involved in fair value decisions, there can be no assurance that a fair value assigned to a particular security is accurate. Notes to Financial Statements SEMIANNUAL REPORT 61 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) INVESTMENT TRANSACTIONS AND INVESTMENT INCOME. Short-term investment transactions are recorded on a trade date basis. Long-term investment transactions are recorded on a trade date plus one basis, except for fiscal quarter ends, which are recorded on trade date. Net realized gains and losses from investment transactions are reported on an identified cost basis. Interest income is recognized using the accrual method and includes accretion of original issue and market discount and amortization of premium. Dividend income is recognized on the ex-dividend date, except that certain dividends from foreign securities are recorded as soon as the information becomes available. FOREIGN CURRENCY TRANSLATION. Except for securities of foreign issuers valued by a pricing service, values of investments and other assets and liabilities denominated in foreign currencies are translated into U.S. dollars using a rate quoted by a major bank or dealer in the particular currency market, as reported by a recognized quotation dissemination service. The Funds do not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments. Reported net realized foreign currency gains or losses arise from disposition of foreign currency, foreign currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amounts of dividends, interest and foreign withholding taxes recorded on the Funds' books on the transaction date and the U.S. dollar equivalent of the amounts actually received or paid. Net unrealized foreign exchange gains and losses arise from changes (due to the changes in the exchange rate) in the value of foreign currency and other assets and liabilities denominated in foreign currencies held at period end. OPTION TRANSACTIONS. For hedging and investment purposes, the Funds may purchase or write (sell) put and call options. One of the risks associated with purchasing an option among others, is that each Fund pays a premium whether or not the option is exercised. Additionally, each of the Funds bear the risk of loss of premium and change in market value should the counterparty not perform under the contract. Put and call options purchased are accounted for in the same manner as portfolio securities. The cost of securities acquired through the exercise of call options is increased by premiums paid. The proceeds from securities sold through the exercise of put options are decreased by the premiums paid. When a Fund writes an option, an amount equal to the premium received by a Fund is recorded as a liability and is subsequently adjusted to the current value of the option written. Premiums received from writing options that expire unexercised are treated by a Fund on the expiration date as realized gains from investments. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or, if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a written call option is exercised, the premium is added to the proceeds from the sale of the underlying security or currency in determining whether a Fund has realized a gain or loss. If a written put option is exercised, the premium reduces the cost basis of the securities purchased by a Fund. A Fund as writer of an option bears the market risk of an unfavorable change in the price of the security underlying the written option. ALLOCATION OF EXPENSES BETWEEN CLASSES. Expenses directly attributable to a Fund are charged to that Fund; other expenses of the Trust are allocated proportionately among each of the Funds within the Trust in relation to the net assets of each Fund or on another reasonable basis. Expenses directly attributable to a particular class of a Fund are charged directly to such class. In calculating the net asset value per share of each class, investment income, realized and unrealized gains and losses and expenses other than class specific expenses are allocated daily to each class of shares based upon the proportion of net assets of each class at the beginning of each day plus current day fund share activity. USE OF ESTIMATES. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates. INCOME TAXES. No provision has been made for income taxes because the Trust's policy is to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code and distribute to shareholders substantially all of its taxable income and gains. 62 SEMIANNUAL REPORT Notes to Financial Statements NOTES TO FINANCIAL STATEMENTS (UNAUDITED) Dividends and distributions paid to shareholders are recorded on the ex-dividend date. The amount of dividends and distributions from net investment income and net realized capital gains is determined in accordance with federal income tax regulations, which may differ from U.S. generally accepted accounting principles. To the extent these "book/tax" differences are permanent in nature such amounts are reclassified within the capital accounts based on their federal tax-basis treatment. These differences are primarily due to differing treatments for foreign currency transactions, contingent payment debt instruments and methods of amortizing and accreting on fixed income securities. The Funds also may treat a portion of the proceeds from each redemption of capital shares as a distribution of taxable net investment income and/or realized capital gain. Financial records are not adjusted for temporary differences. INDEMNIFICATIONS. Under the Funds' organizational documents, its Officers and Trustees are indemnified against certain liabilities arising out of the performance of their duties to the Funds. In addition, in the normal course of business, the Trust enters into contracts that provide general indemnifications to other parties. Each Funds' maximum exposure under these arrangements is unknown as this would involve future claims that may be made against each Fund that have not yet occurred. However, the Funds have not had prior claims or losses pursuant to these contracts and expect the risk of loss to be remote. NOTE 2 - INVESTMENT ADVISER AND TRANSACTIONS WITH AFFILIATES OR CERTAIN OTHER PARTIES Pursuant to an investment advisory agreement with Calamos Advisors LLC ("Calamos Advisors"), each Fund pays a monthly investment advisory fee based on the average daily net assets of each Fund, computed as follows: The Growth and Income Fund, Convertible Fund, and Market Neutral Fund fees are at the annual rate of 0.75% of the first $500 million of average daily net assets, 0.70% of the next $500 million of average daily net assets, 0.65% of average daily net assets in excess of $1 billion. The High Yield Fund fee is at the annual rate of 0.75% of the Fund's average daily net assets. The Growth Fund pays a fee at the annual rate of 1.00% of the first $500 million of the Growth Fund's average daily net assets, .90% of the next $500 million of average daily net assets, ..80% of the next $5 billion of average daily net assets (average daily net assets in excess of $1 billion to $6 billion), .78% of the next $5 billion of average daily net assets (average daily net assets in excess of $6 billion to $11 billion), .76% of the next $5 billion of average daily net assets (average daily net assets in excess of $11 billion to $16 billion), .74% of the next $5 billion of average daily net assets (average daily net assets in excess of $16 billion to $21 billion), .72% of the next $5 billion of average daily net assets (average daily net assets in excess of $21 billion to $26 billion) and .70% of average daily net assets in excess of $26 billion. The Blue Chip Fund, Value Fund, and Global Growth and Income Fund fees are at the annual rate of 1.00% of each Fund's average daily net assets. The International Growth Fund pays a fee based on average daily net assets of the Fund that is accrued daily and paid on a monthly basis, except for the performance fee, which will be accrued and paid on a monthly basis beginning in March 2006. The performance adjustment equally increases or decreases the management fee, on a monthly basis, by 1/12 of 0.03% of the Fund's average daily net assets for each full 1% increment amount by which the Fund outperforms or underperforms the MSCI EAFE Growth Index ("Index") on an annualized basis, respectively. The base fee is at the annual rate of 1.00% of the first $500 million of International Growth Fund's average daily net assets, 0.95% of the next $500 million of average daily net assets, 0.90% of the next $5 billion of average daily net assets (average daily net assets in excess of $1 billion to $6 billion), 0.88% of the next $5 billion of average daily net assets (average daily net assets in excess of $6 billion to $11 billion), 0.86% of the next $5 billion of average daily net assets (average daily net assets in excess of $11 billion to $16 billion), 0.84% of the next $5 billion of average daily net assets (average daily net assets in excess of $16 billion to $21 billion), 0.82% of the next $5 billion of average daily net assets (average daily net assets in excess of $21 billion to $26 billion) and 0.80% of average daily net assets in excess of $26 billion. The performance adjustment rate is calculated by comparing over the performance period the Fund's performance to that of the Index. The performance period for International Growth Fund commenced at the beginning of its first full month of operation and will eventually include 36 months. Starting with twelfth month, the performance adjustment takes effect. Each month subsequent to the twelfth month, new month is added to the performance period until the performance period includes 36 months. Thereafter, the performance period consists of the most recent month plus the previous 35 months. Notes to Financial Statements SEMIANNUAL REPORT 63 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) The performance comparison is made at the end of each month. The maximum annualized performance adjustment rate is +/-0.30% of International Growth Fund's average daily net assets over the performance period. The performance adjustment rate is divided by twelve and multiplied by the Fund's average daily net assets over the performance period, and the resulting dollar amount is then added to or subtracted from the base fee. CALAMOS ADVISORS may receive a positive performance adjustment even if the Fund has a negative return over a performance period if it otherwise outperforms the Index during that period. Calamos Advisors receives a fee payable monthly at the annual rate of 0.0175% on the first $1 billion of combined assets; 0.0150% on the next $1 billion of combined assets; and 0.0110% on combined assets above $2 billion for financial accounting services. For purposes of this calculation combined assets means the net assets of Calamos Investment Trust, Calamos Advisors Trust, and the managed net assets of Calamos Convertible and High Income Fund, Calamos Strategic Total Return Fund, and Calamos Convertible Opportunities and Income Fund. Financial accounting services include, but are not limited to, the following: managing expenses and expense payment processing; monitoring the calculation of expense accrual amounts; calculating, tracking, and reporting tax adjustments on all assets and monitoring trustee deferred compensation plan accruals and valuations. The Funds pay their pro rata share of the financial accounting services fee payable to Calamos Advisors based on average net assets of the Funds. Effective August 1, 2005, the Trust began reimbursing the advisor for compensation paid to the Chief Compliance Officer of the Trust. This compensation is reported as part of "Other" expenses on the Statement of Operations. Calamos Advisors has contractually agreed to limit the annual ordinary operating expenses of each Fund, as a percentage of the average daily net assets of the particular class of shares, to 1.75% for Class A shares, 2.50% for Class B shares, 2.50% for Class C shares, and 1.50% for Class I shares through August 31, 2006. As of September 30, 2005, there were no expenses waived or absorbed. As Distributor, CALAMOS FINANCIAL SERVICES LLC ("CFS") assumed all expenses of personnel, office space, office facilities and equipment incidental to such service. Each Fund has adopted a Distribution Plan pursuant to Rule 12b-1 under the Investment Company Act of 1940 whereby the Fund pays to CFS an annual distribution and/or service fee of 0.25% of the average daily net assets of the Fund's Class A shares and an annual service fee of 0.25% and an annual distribution fee of 0.75% of the average daily net assets of the Fund's Class B shares and Class C shares. CFS also receives a sales commission and/or an underwriting fee on certain sales of each Fund's Class A shares. During the six months ended September 30, 2005, CFS received commissions and distribution fees of $2,211,818, $15,820, $15,355 $41,446, $61,291, $881,282 and $31,533 from the sale of shares of Growth Fund, Blue Chip Fund, Value Fund, International Growth Fund, Global Growth and Income Fund, Growth and Income Fund and High Yield Fund, respectively. Furthermore, pursuant to an agreement with US Bancorp Fund Services, LLC, the Funds' transfer agent ("US Bancorp"), CFS provides certain shareholder administrative services to US Bancorp. Effective as of September 1, 2005, CFS will receive an annual fee of $175,000, paid in monthly installments, for providing of these services. Also, US Bancorp pays license fees to unaffiliated third parties for CFS' utilization of certain transfer agent and phone systems in the providing of these services. The fees paid to CFS and the payment of license fees to third parties are borne by US Bancorp. The Funds have not assumed or incurred any additional expenses in connection with CFS providing these services to US Bancorp and the transfer agency fees payable by the Funds to US Bancorp have not increased as a result thereof. Certain officers and trustees of the Trust are also officers and directors of CFS and Calamos Advisors. All officers and affiliated trustees serve without direct compensation from the Trust. The Funds' Statement of Additional Information contains additional information about the Funds' trustees and is available upon request without charge by calling our toll free number (800) 582-6959. Certain affiliates of the advisor hold material investments in the Funds. As of September 30, 2005 affiliates of the advisor held 15%, 17% and 49% of the outstanding shares for the Blue Chip Fund, Value Fund and International Growth Fund, respectively. The Trust has adopted a deferred compensation plan (the "Plan"). Under the Plan, a trustee who is not an "interested person" of Calamos Advisors and has elected to participate in the Plan (a "participating trustee") may defer receipt of all or a portion of his compensation from the Trust. The deferred compensation payable to the participating trustee is credited to the trustee's deferral account as of the business day such compensation would have been paid to the participating trustee. The value of a participating trustee's deferred 64 SEMIANNUAL REPORT Notes to Financial Statements NOTES TO FINANCIAL STATEMENTS (UNAUDITED) compensation account at any time is equal to what would be the value if the amounts credited to the account had instead been invested in shares of one or more of the Funds of the Calamos Investment Trust as designated by the trustee. Thus, the value of the account increases with contributions to the account or with increases in the value of the measuring shares, and the value of the account decreases with withdrawals from the account or with declines in the value of the measuring shares. If a participating trustee retires, the trustee may elect to receive payments under the plan in a lump sum or in equal installments over a period of five years. If a participating trustee dies, any amount payable under the Plan will be paid to the trustee's beneficiaries. Deferred compensation investments of $38,429 for the Growth Fund, $13,360 for the Blue Chip Fund, $21,263 for the Value Fund, $4,289 for the International Growth Fund, $23,751 for the Global Growth and Income Fund, $28,421 for the Growth and Income Fund, $23,636 for the High Yield Fund, $24,543 for the Convertible Fund and $23,871 for the Market Neutral Fund are included in "Other assets" on the Statements of Assets and Liabilities at September 30, 2005. Each Fund's obligation to make payments under the Plan is a general obligation of that Fund and is included in "Accounts payable and accrued liabilities" on the Statement of Assets and Liabilities at September 30, 2005.

A Fund may sell a security it does not own in anticipation of a decline in the fair value of that security. When a Fund sells a security short, it must borrow the security sold short and deliver it to the broker-dealer through which it made the short sale. Dividends paid on securities sold short are disclosed as an expense on the statement of operations. A gain, limited to the price at which the Fund sold the security short, or a loss, unlimited in size, will be recognized upon the termination of a short sale. So long as the short position is open, the Fund must adjust daily the value of the segregated account so that the amount deposited in it, plus any amount deposited with the broker as collateral, will equal the current market value of the security sold short. However, the value of the segregated account may not be reduced below the point at which the segregated account, plus any amount deposited with the broker, is equal to the market value of the securities sold short at the time they were sold short. NOTE 6 - FORWARD FOREIGN CURRENCY CONTRACTS Each Fund may engage in portfolio hedging with respect to changes in currency exchange rates by entering into foreign currency contracts to purchase or sell currencies. A forward foreign currency contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated forward rate. Risks associated with such contracts include, among other things, movement in the value of the foreign currency relative to the U.S. dollar and the ability of the counterparty to perform. The net unrealized gain, if any, represents the credit risk to the Fund on a forward foreign currency contract. The contracts are valued daily at forward exchange rates and an unrealized gain or loss is recorded. The Fund realizes a gain or loss upon settlement of the contracts. The counterparty to all forward foreign currency contracts at September 30, 2005, was a multinational bank. Notes to Financial Statements SEMIANNUAL REPORT 67 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) As of September 30, 2005, the Global Growth and Income Fund had the following open forward foreign currency contracts: SETTLEMENT LOCAL CURRENT UNREALIZED DATE CURRENCY VALUE GAIN (LOSS) ---------- ------------- ---------- ----------- SHORT CONTRACTS Australian Dollar 10/27/05 14,065,000 10,711,965 $(100,097) Brazilian Real 10/27/05 2,377,000 1,059,593 (104,973) British Pound Sterling 10/27/05 15,970,000 28,151,156 (199,852) Canadian Dollar 10/27/05 2,195,000 1,890,350 (106,667) Euro 10/27/05 46,735,000 56,235,741 487,229 Hong Kong Dollar 10/27/05 62,255,000 8,014,212 (4,724) Hungarian Forint 10/27/05 895,210,000 4,306,578 120,813 Indonesian Rupiah 10/27/05 208,700,000 4,748,536 28,168 Japanese Yen 10/27/05 6,635,885,000 58,633,999 985,540 Singapore Dollar 10/27/05 2,800,000 1,657,033 33,013 Swedish Krona 10/27/05 29,575,000 3,822,638 (31,214) Swiss Franc 10/27/05 32,595,000 25,246,004 201,697 Taiwanese Dollar 10/27/05 323,830,000 9,779,643 412,370 ---------- $1,721,303 As of September 30, 2005, the Convertible Fund had the following open forward foreign currency contracts: SETTLEMENT LOCAL CURRENT UNREALIZED DATE CURRENCY VALUE GAIN (LOSS) ---------- ------------- ----------- ----------- SHORT CONTRACTS British Pound Sterling 10/27/05 11,700,000 $20,624,203 $(145,796) Euro 10/27/05 8,720,000 10,492,686 84,500 Swiss Franc 10/27/05 40,510,000 31,376,457 226,266 --------- $ 164,970 NOTE 7 - SYNTHETIC CONVERTIBLE SECURITIES The Funds may establish a "synthetic" convertible instrument by combining separate securities that possess the economic characteristics similar to a convertible security, i.e., fixed-income securities ("fixed-income component") and the right to acquire equity securities ("convertible component"). The fixed-income component is achieved by investing in non-convertible, fixed income securities such as bonds, preferred stocks and money market instruments. The convertible component is achieved by investing in warrants or options to buy common stock at a certain exercise price, or options on a stock index. In establishing a synthetic instrument, the Funds may pool a basket of fixed-income securities and a basket of warrants or options that produce the economic characteristics similar to a convertible security. Within each basket of fixed-income securities and warrants or options, different companies may issue the fixed-income and convertible components, which may be purchased separately and at different times. The Funds may purchase synthetic securities created by other parties, typically investment banks, including convertible structured notes. Convertible structured notes are fixed-income debentures linked to equity. Convertible structured notes have the attributes of a convertible security; however, the investment bank that issued the convertible note assumes the credit risk associated with the investment, rather than the issuer of the underlying common stock into which the note is convertible. Purchasing synthetic convertible securities may offer more flexibility than purchasing a convertible security. Different companies may issue the fixed-income and convertible components, which may be purchased separately and at different times. 68 SEMIANNUAL REPORT Notes to Financial Statements NOTES TO FINANCIAL STATEMENTS (UNAUDITED) NOTE 8 - SECURITIES LENDING For the six months ended September 30, 2005 the Funds loaned certain of its securities to broker-dealers and banks. Any such loan must be continuously secured by collateral in cash or cash equivalents maintained on a current basis in an amount at least equal to the market value of the securities loaned by the Funds. The Funds continue to receive the equivalent of the interest or dividends paid by the issuer on the securities loaned and also receive an additional return that may be in the form of a fixed fee or a percentage of the collateral. The Funds may pay reasonable fees to persons unaffiliated with the Funds for services in arranging these loans. The Funds have the right to call the loan and obtain the securities loaned at any time on notice of not more than five business days. The Funds do not have the right to vote the securities during the existence of the loan but could call the loan in an attempt to permit voting of the securities in certain circumstances. Upon return of the securities loaned, the cash or cash equivalent collateral will be returned to the borrower. In the event of bankruptcy or other default of the borrower, the Funds could experience both delays in liquidating the loan collateral or recovering the loaned securities and losses, including (a) possible decline in the value of the collateral or in the value of the securities loaned during the period while the Funds seek to enforce its rights thereto, (b) possible subnormal levels of income and lack of access to income during this period, and (c) the expenses of enforcing their rights. In an effort to reduce these risks, Calamos Advisors LLC and the security lending agent will monitor the creditworthiness of the firms to which the Fund lends securities. At September 30, 2005, the Growth Fund, Blue Chip Fund, Value Fund, Global Growth and Income Fund, Growth and Income Fund, High Yield Fund, and Convertible Fund had securities valued at $2,411,009,112, $21,908,497, $20,505,763, $40,303,258, $676,068,329, $44,737,085, and, $179,084,825, respectively, on loan to broker-dealers and banks and Growth Fund, Blue Chip Fund, Value Fund, Global Growth and Income Fund, Growth and Income Fund, High Yield and Convertible Fund had $2,451,221,285, $22,489,467, $21,163,297, $41,175,859, $693,063,438, $45,865,015 and $183,084,217, respectively, in cash collateral. NOTE 9 - REDEMPTION FEE A redemption of Class A, Class B, Class C and Class I shares of a Fund (except shares purchased with reinvested dividends or distributions) held for five days or less may be subject to a redemption fee of 2% of the redemption proceeds that will be deducted from those proceeds. The redemption fee is intended to deter short-term trading. The redemption fee is also intended to offset portfolio transaction costs, market impact, and other costs associated with short-term trading. If the shares redeemed were purchased on different days, the shares held shortest will be redeemed first for purposes of determining whether the redemption fee applies. The redemption fee is not a sales charge; it is retained by the Fund and reflected as an addition to paid in capital and does not benefit the Funds Advisor or any other third party.

Management Agreement The Board of Trustees of Calamos Investment Trust oversees the management of each of the Funds, and, as required by law, determines annually whether to continue the Trust's management agreement with Calamos Advisors under which Calamos Advisors serves as the investment manager and administrator for the Trust and each of the Fund's. In connection with their most recent consideration of that agreement, the Trustees received and reviewed information provided by Calamos Advisors in response to detailed requests of the Independent Trustees and their independent legal counsel and discussed with representatives of Calamos Advisors' the operations of the Funds and the nature and quality of the advisory and other services provided by Calamos Advisors to the Funds. The Trustees also received and reviewed a memorandum from counsel to the Independent Trustees regarding the Trustee's responsibilities in evaluating the management agreement. In the course of their consideration of the agreement the Independent Trustees were advised by their counsel, and in addition to meeting with management of Calamos Advisors they met separately in executive session with their counsel. At a meeting on June 30, 2005, based on their evaluation of the information referred to above and other information, the Trustees determined that the overall arrangements between the Funds and Calamos Advisors were fair and reasonable in light of the nature and quality of the services provided by Calamos Advisors and its affiliates, the fees charged for those services and other matters that the Trustees considered relevant in the exercise of their business judgment. At that meeting the Trustees, including all of the Independent Trustees, unanimously approved continuation of the management agreement through August 1, 2006, subject to earlier termination as provided in the agreement. In considering the continuation of the management agreement, the Trustees reviewed and analyzed various factors that they determined were relevant, including the factors described below, none of which by itself was considered dispositive. However, the material factors and conclusions that formed the basis for the Trustees' determination to approve the continuation of the management agreement are discussed separately below. NATURE, QUALITY AND EXTENT OF SERVICES The Trustees reviewed the nature, extent and quality of Calamos Advisors' services to the Funds, taking into account the investment objective and strategy of each Fund and the knowledge of the Trustees gained from their regular meetings with management on at least a quarterly basis. In addition, the Trustees reviewed Calamos Advisors' resources and key personnel, especially those who provide investment management services to the Funds. The Trustees also considered other services provided to the Funds by Calamos Advisors, such as managing the execution of portfolio transactions and the selection of broker-dealers for those transactions, serving as the Funds' administrator, monitoring adherence to the Funds' investment restrictions, producing shareholder reports, providing support services for the Board and Board committees, communicating with shareholders and overseeing the activities of other service providers, Trustee Approval of Management Agreement SEMIANNUAL REPORT 103 Trustee Approval of Management Agreement including monitoring compliance with various Fund policies and procedures and with applicable securities laws and regulations. The Trustees concluded that the nature and extent of the services provided by Calamos Advisors to each Fund were appropriate and consistent with the terms of the management agreement, that the quality of those services had been consistent with or superior to quality norms in the industry and that the Funds were likely to benefit from the continued provision of those services. They also concluded that Calamos Advisors had sufficient personnel, with the appropriate education and experience, to serve the Funds effectively and had demonstrated its continuing ability to attract and retain well qualified personnel. PERFORMANCE OF THE FUNDS The Trustees considered the performance results for each of the Funds over various time periods. They reviewed information comparing each Fund's performance with the performance of comparable funds and peer groups identified by Lipper Inc., an independent provider of investment company data, and with the Fund's benchmark. The Trustees noted that the long-term performance of each Fund that had been in operation for more than two years compared favorably with its relevant peer group and benchmark, with each of the Funds, except Value Fund, placing in the top quintile in relation to its peer group for the five year performance period, and with Value Fund, due to its inception date, placing in the top quintile in relation to its peer group for the three year performance period. Blue Chip Fund and International Growth Fund had commenced operations in December 2003 and March 2005, respectively, and thus did not have long-term performance records. The Trustees concluded that, although past performance is not necessarily indicative of future results, the Funds strong longer term performance was an important factor in the Trustees' evaluation of the quality of services provided by Calamos Advisors under the management agreement. COSTS OF SERVICES AND PROFITS REALIZED BY CALAMOS ADVISORS The Trustees examined information on fees and expenses of each Fund in comparison to information for other comparable funds as provided by Lipper. Also, the Trustees reviewed information on fees and expenses for additional funds identified by Calamos Advisors. The Trustees noted that both the contractual rates of management fees and the actual management fees after fee waivers for most of the Funds were greater than the median management fees of the respective Lipper peer groups. They also noted, however, that the overall expense ratios of most of the Funds were below or not appreciably higher than the median expense ratios of their respective peer groups. The Trustees considered the methodology used by Calamos Advisors in determining compensation payable to portfolio managers, the very competitive environment for investment management talent, and the competitive market for mutual funds in different distribution channels. 104 SEMIANNUAL REPORT Trustee Approval of Management Agreement Trustee Approval of Management Agreement The Trustees reviewed information on the profitability of Calamos Advisors in serving as each Fund's investment manager and of Calamos Advisors and its affiliates in all of their relationships with each Fund, as well as an explanation of the methodology utilized in allocating various expenses among the Funds and other business units. The Trustees recognized that profitability comparisons among fund managers are difficult because very little comparative information is publicly available and profitability of any manager is affected by numerous factors, including the organizational structure of the particular manager, the types of funds and other accounts it manages, possible other lines of business, the methodology for allocating expenses and the manager's capital structure and cost of capital. However, based on the information available and taking those factors into account, the Trustees concluded that the profitability of Calamos Advisors regarding each Fund in relation to the services rendered was not unreasonable. The Trustees also reviewed Calamos Advisors' management fees for its institutional separate accounts and for its subadvised funds (for which Calamos Advisors provides portfolio management services only). Although in most instances its sub-advisory, and in many instances its institutional separate account, fees for various investment strategies are lower than the management fees charged to the Funds with corresponding strategies, the Trustees noted that Calamos Advisors performs significant additional services for the Funds that it does not provide to those other clients, including administrative services, oversight of the Funds' other service providers, trustee support, regulatory compliance and numerous other services. Finally, the Trustees considered the financial condition of Calamos Advisors, which they found to be sound. The Trustees concluded that the management fees and other compensation payable by the Funds to Calamos Advisors and its affiliates were reasonable in relation to the nature and quality of the services to be provided, taking into account the fees charged by other advisors for managing comparable mutual funds with similar strategies and the fees Calamos Advisors charges to other clients. The Trustees also concluded that the Funds' estimated overall expense ratios, taking into account quality of services provided by Calamos Advisors, the investment performance of the Funds' and the expense limitations agreed to by Calamos Advisors, were also reasonable. ECONOMIES OF SCALE The Trustees noted that the advisory fee schedule for each Fund except Blue Chip Fund, Global Growth and Income Fund, High Yield Fund and Value Fund contains breakpoints that reduce the fee rate on assets above specified levels. The Trustees received and discussed information concerning whether Calamos Advisors realizes economies of scale as a Fund's assets increase. The Trustee Approval of Management Agreement SEMIANNUAL REPORT 105 Trustee Approval of Management Agreement Trustees also considered Calamos Advisors' agreement to reimburse each of the Funds for any ordinary operating expenses (excluding 12b-1 fees) for a fiscal year above 1.50% of average net assets, subject, in the case of International Growth Fund, to an upward or downward adjustment of such limitation for any period equal to the performance fee adjustment applicable to that Fund for the period. The Trustees concluded that the fee schedule for each Fund currently in effect represents an appropriate sharing of economies of scale at current asset levels, but concluded to continue their periodic consideration of economies of scale. OTHER BENEFITS TO CALAMOS ADVISORS The Trustees also considered benefits that accrue to Calamos Advisors and its affiliates from their relationship with the Funds. The Trustees concluded that, other than the services to be provided by Calamos Advisors and its affiliates pursuant to the management agreement and the fees payable by the Funds therefor, the Funds and Calamos Advisors may potentially benefit from their relationship with each other in other ways. Recognizing that an affiliate of Calamos Advisors serves the Funds as distributor and receives compensation from the Funds for its services to the Funds, the Trustees determined that such compensation was fair and reasonable. The Trustees also considered Calamos Advisors' use of commissions to be paid by the Funds on their portfolio brokerage transactions to obtain proprietary research products and services benefiting the Funds and/or other clients of Calamos Advisors. The Trustees concluded that Calamos Advisors' use of "soft" commission dollars to obtain research products and services was consistent with regulatory requirements and is beneficial to the Funds. They concluded that, although Calamos Advisors derives or may derive additional benefits through the use of soft dollars from the Funds portfolio transactions, the Funds also benefit from the receipt of research products and services to be acquired through commissions paid on the portfolio transactions of other clients of Calamos Advisors. They also concluded that the Funds success could attract other business to Calamos Advisors or its other funds and that Calamos Advisors' success could enhance its ability to serve the Funds. After full consideration of the above factors as well as other factors that were instructive in analyzing the management arrangements, the Trustees, including all of the Independent Trustees, concluded that the continuation of the management agreement was in the best interest of each Fund and its shareholders. 106 SEMIANNUAL REPORT Trustee Approval of Management Agreement This page intentionally left blank.
