THE GAMCO GROWTH FUND ANNUAL REPORT DECEMBER 31, 2005 TO OUR SHAREHOLDERS, The Sarbanes-Oxley Act requires a Fund's principal executive and financial officers to certify the entire contents of the semi-annual and annual shareholder reports in a filing with the Securities and Exchange Commission on Form N-CSR. This certification would cover the portfolio manager's commentary and subjective opinions if they are attached to or a part of the financial statements. Many of these comments and opinions would be difficult or impossible to certify. Because we do not want our portfolio managers to eliminate their opinions and/or restrict their commentary to historical facts, we have separated their commentary from the financial statements and investment portfolio and have sent it to you separately. Both the commentary and the financial statements, including the portfolio of investments, will be available on our website at www.gabelli.com/funds. Enclosed are the audited financial statements and the investment portfolio as of December 31, 2005 with a description of factors that affected the performance during the past year. PERFORMANCE DISCUSSION The year was similar to 2004. Strong earnings overcame Fed interest rate increases, natural disasters and soaring energy prices to lift stocks higher. Returns were strong in energy and materials related issues and varied widely across and within other sectors. For the year, large-cap growth stocks staged a comeback of sorts, and we fully participated in the market's advance. We were fortunate to have a number of holdings perform well, especially in the energy, healthcare, information technology and materials areas. For the 12 months ended December 31, 2005, the Fund returned 10.30% compared to 4.91% for the S&P 500 and 5.26% for the Russell 1000 Growth Index. For the year, energy was far and away the top performing sector, according to Standard & Poor's, with the sector returning 29.1%. The next best sector was Utilities, with a gain of 12.8%, a group we did not participate in. Our relatively good results were driven by strong energy and materials holdings, along with exceptional returns from certain healthcare and information technology stocks. Our top-performing holding was healthcare services company Express Scripts Inc. (+119%), followed by Burlington Resources Inc. (+98%), Suncor Energy Inc. (+78%), Google Inc. (+71% from purchase price during year) and Genentech Inc. (+70%). Other winners were Allegheny Technologies Inc. (+67%), Transocean Inc. (+64%), Whole Foods Market Inc. (+62%), Alcon Inc. (+61%) and Devon Energy Corp. (+61%). These companies all had robust earnings gains in 2005, which propelled their shares higher. Our weakest holdings for the year were Dell Inc. (-29%), Sysco Corp. (-19%), Zimmer Holdings Inc. (-16%), Biomet Inc. (-16%), Harley-Davidson Inc. (-15%), Electronic Arts Inc. (-15%), News Corp. (-14%), UPS Inc. (-12%), Wal-Mart Stores Inc. (-11%) and Cisco Systems Inc. (-11%). There is no real theme here as these companies were for the most part grappling with different issues. The weakest S&P industry sector was telecommunication services, which fell 9.0%. Our performance was helped by the absence of investments in this sector. Sincerely yours, /s/ Bruce N. Alpert Bruce N.

All mutual funds have operating expenses. As a shareholder of a fund, you incur ongoing costs, which include costs for portfolio management, administrative services, and shareholder reports (like this one), among others. Operating expenses, which are deducted from a fund's gross income, directly reduce the investment return of a fund. When a fund's expenses are expressed as a percentage of its average net assets, this figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your Fund and to compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period shown and held for the entire period. The Expense Table below illustrates your Fund's costs in two ways: ACTUAL FUND RETURN: This section provides information about actual account values and actual expenses. You may use this section to help you to estimate the actual expenses that you paid over the period after any fee waivers and expense reimbursements. The "Ending Account Value" shown is derived from the Fund's ACTUAL return during the past six months, and the "Expenses Paid During Period" shows the dollar amount that would have been paid by an investor who started with $1,000 in the Fund. You may use this information, together with the amount you invested, to estimate the expenses that you paid over the period. To do so, simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number given for your Fund under the heading "Expenses Paid During Period" to estimate the expenses you paid during this period. HYPOTHETICAL 5% RETURN: This section provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio. It assumes a hypothetical annualized return of 5% before expenses during the period shown. In this case - because the hypothetical return used is NOT the Fund's actual return - the results do not apply to your investment and you cannot use the hypothetical account value and expense to estimate the actual ending account balance or expenses you paid for the period. This example is useful in making comparisons of the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in shareholder reports of other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs such as sales charges (loads), redemption fees, or exchange fees, if any, which are described in the Prospectus. If these costs were applied to your account, your costs would be higher. Therefore, the 5% hypothetical return is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. The "Annualized Expense Ratio" represents the actual expenses for the last six months and may be different from the expense ratio in the Financial Highlights which is for the year ended December 31, 2005.

ORGANIZATION. The GAMCO Growth Fund (the "Fund"), formerly The Gabelli Growth Fund, was organized on October 24, 1986 as a Massachusetts business trust. The Fund is a diversified open-end management investment company registered under the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund's primary objective is capital appreciation. The Fund commenced investment operations on April 10, 1987. 2. SIGNIFICANT ACCOUNTING POLICIES. The preparation of financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements. SECURITY VALUATION. Portfolio securities listed or traded on a nationally recognized securities exchange or traded in the U.S. over-the-counter market for which market quotations are readily available are valued at the last quoted sale price or a market's official closing price as of the close of business on the day the securities are being valued. If there were no sales that day, the security is valued at the average of the closing bid and asked prices or, if there were no asked prices quoted on that day, then the security is valued at the closing bid price on that day. If no bid or asked prices are quoted on such day, the security is valued at the most recently available price or, if the Board of Trustees (the "Board") so determines, by such other method as the Board shall determine in good faith, to reflect its fair market value. Portfolio securities traded on more than one national securities exchange or market are valued according to the broadest and most representative market, as determined by Gabelli Funds, LLC (the "Adviser"). Portfolio securities primarily traded on foreign markets are generally valued at the preceding closing values of such securities on their respective exchanges or if after the close of the foreign markets, but prior to the close of business on the day the securities are being valued, market conditions change significantly, certain foreign 8 THE GAMCO GROWTH FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) ================================================================================ securities may be fair valued pursuant to procedures established by the Board. Debt instruments with remaining maturities of 60 days or less that are not credit impaired are valued at amortized cost, unless the Board determines such amount does not reflect the securities' fair value, in which case these securities will be valued at their fair value as determined by the Board. Debt instruments having a maturity greater than 60 days for which market quotations are readily available are valued at the average of the latest bid and asked prices. If there were no asked prices quoted on such day, the security is valued using the closing bid price. Futures contracts are valued at the closing settlement price of the exchange or board of trade on which the applicable contract is traded. Securities and assets for which market quotations are not readily available are valued at their fair value as determined in good faith under procedures established by and under the general supervision of the Board. Fair valuation methodologies and procedures may include, but are not limited to: analysis and review of available financial and non-financial information about the company; comparisons to the valuation and changes in valuation of similar securities, including a comparison of foreign securities to the equivalent U.S. dollar value ADR securities at the close of the U.S. exchange; and evaluation of any other information that could be indicative of the value of the security. FOREIGN SECURITIES. The Fund may directly purchase securities of foreign issuers. Investing in securities of foreign issuers involves special risks not typically associated with investing in securities of U.S. issuers. The risks include possible revaluation of currencies, the ability to repatriate funds, less complete financial information about companies and possible future adverse political and economic developments. Moreover, securities of many foreign issuers and their markets may be less liquid and their prices more volatile than those of securities of comparable U.S. issuers. FOREIGN TAXES. The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests. SECURITIES TRANSACTIONS AND INVESTMENT INCOME. Securities transactions are accounted for on the trade date with realized gain or loss on investments determined by using the identified cost method. Interest income (including amortization of premium and accretion of discount) is recorded on the accrual basis. Premiums and discounts on debt securities are amortized using the yield to maturity method. Dividend income is recorded on the ex-dividend date except for certain dividends which are recorded as soon as the Fund is informed of the dividend. DETERMINATION OF NET ASSET VALUE AND CALCULATION OF EXPENSES. Certain administrative expenses are common to, and allocated among, various affiliated funds. Such allocations are made on the basis of each fund's average net assets or other criteria directly affecting the expenses as determined by the Adviser pursuant to procedures established by the Board. In calculating net asset value ("NAV") per share of each class, investment income, realized and unrealized gains and losses, redemption fees, 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. Distribution expenses are borne solely by the class incurring the expense. CUSTODIAN FEE CREDITS. When cash balances are maintained in the custody account, the Fund receives credits which are used to offset custodian fees. The gross expenses paid under the custody arrangement are included in custodian fees in the Statement of Operations with the corresponding expense offset shown as "custodian fee credits". 9 THE GAMCO GROWTH FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) ================================================================================ DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS. Dividends and distributions to shareholders are recorded on the ex-dividend date. Distributions to shareholders are based on ordinary income and long-term capital gains as determined in accordance with Federal income tax regulations, which may differ from income and capital gains as determined under U.S. generally accepted accounting principles. These differences are primarily due to differing treatments of income and gains on various investment securities held by the Fund, timing differences, and differing characterizations of distributions made by the Fund. These book/tax differences are either temporary or permanent in nature. To the extent these differences are permanent, adjustments are made to the appropriate equity accounts in the period when the differences arise. These reclassifications have no impact on the NAV of the Fund and the calculation of net investment income per share in the Financial Highlights excludes these adjustments. For the year ended December 31, 2005, reclassifications were made to decrease accumulated net investment loss by $6,096,798, with an offsetting adjustment to additional paid-in capital. No distributions were made in the fiscal years ended December 31, 2005 and 2004. PROVISION FOR INCOME TAXES. The Fund intends to continue to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"). It is the policy of the Fund to comply with the requirements of the Code applicable to regulated investment companies and to distribute substantially all of its net investment company taxable income and net capital gains. Therefore, no provision for Federal income taxes is required. At December 31, 2005, the difference between book basis and tax basis unrealized appreciation was primarily attributable to the tax deferral of losses on wash sales. As of December 31, 2005, the components of accumulated earnings/(losses) on a tax basis were as follows: Accumulated capital loss carryforward ................. $(1,052,343,474) Net unrealized appreciation ........................... 158,514,873 --------------- Total accumulated loss ................................ $ (893,828,601) =============== At December 31, 2005, the Fund has net capital loss carryforwards for Federal income tax purposes of $1,052,343,474, which are available to reduce future required distributions of net capital gains to shareholders. $701,151,305 of the loss carryforward is available through 2010; $350,050,494 is available through 2011; and $1,141,675 is available through 2012. For the year ended December 31, 2005 the Fund utilized capital loss carryforwards of $110,960,677. The following summarizes the tax cost of investments and related unrealized appreciation/depreciation at December 31, 2005: GROSS GROSS NET UNREALIZED UNREALIZED UNREALIZED APPRECIATION/ COST APPRECIATION DEPRECIATION (DEPRECIATION) ---- ------------ ------------ -------------- Investments ............... $985,697,488 $194,206,472 $(35,691,599) $158,514,873 3. INVESTMENT ADVISORY AGREEMENT. The Fund has entered into an investment advisory agreement (the "Advisory Agreement") with the Adviser which provides that the Fund will pay the Adviser a fee, computed daily and paid monthly, at the annual rate of 1.00% of the value of its average daily net assets. In accordance with the Advisory Agreement, the Adviser provides a continuous investment program for the Fund's portfolio, oversees the administration of all aspects of the Fund's business and affairs, and pays the compensation of all Officers and Trustees of the Fund who are affiliated persons of the Adviser. 10 THE GAMCO GROWTH FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) ================================================================================ 4. DISTRIBUTION PLAN. The Fund's Board has adopted a distribution plan (the "Plan") for each class of shares pursuant to Rule 12b-1 under the 1940 Act. Gabelli & Company, Inc. ("Gabelli & Company"), an affiliate of the Adviser, serves as distributor of the Fund. Under the Class AAA, Class A, Class B, and Class C Share Plans, payments are authorized to Gabelli & Company at annual rates of 0.25%, 0.25%, 1.00%, and 1.00%, respectively, of the average daily net assets of those classes, the annual limitations under each Plan. Such payments are accrued daily and paid monthly. 5. PORTFOLIO SECURITIES. Purchases and proceeds from the sales of securities for the year ended December 31, 2005, other than short-term securities, aggregated $493,884,741 and $925,954,385, respectively. 6. TRANSACTIONS WITH AFFILIATES. During the year ended December 31, 2005, the Fund paid brokerage commissions of $17,000 to Gabelli & Company. During the year ended December 31, 2005, Gabelli & Company informed the Fund that it received $1,575 from investors representing commissions (sales charges and underwriting fees) on sales and redemptions of Fund shares. The cost of calculating the Fund's NAV per share is a Fund expense pursuant to the Advisory Agreement between the Fund and the Adviser. During the year ended December 31, 2005, the Fund reimbursed the Adviser $45,000 in connection with the cost of computing the Fund's NAV, which is included in miscellaneous expenses in the Statement of Operations. 7. LINE OF CREDIT. The Fund has access to an unsecured line of credit of up to $25,000,000 from the custodian for temporary borrowing purposes. Borrowings under this arrangement bear interest at 0.75% above the Federal Funds rate on outstanding balances. During the year ended December 31, 2005 there were no borrowings from the line of credit. 8. SHARES OF BENEFICIAL INTEREST. The Fund currently offers four classes of shares -- Class AAA Shares, Class A Shares, Class B Shares, and Class C Shares. Class AAA Shares are offered only to investors who acquire them directly from Gabelli & Company or through selected broker/dealers without a sales charge. Class A Shares are subject to a maximum front-end sales charge of 5.75%. Class B Shares are subject to a contingent deferred sales charge ("CDSC") upon redemption within six years of purchase and automatically convert to Class A Shares approximately eight years after the original purchase. The applicable CDSC is equal to a declining percentage of the lesser of the NAV per share at the date of the original purchase or at the date of redemption, based on the length of time held. Class C Shares are subject to a 1% CDSC for one year after purchase. Class B Shares are available only through exchange of Class B Shares of other funds distributed by Gabelli & Company. The Board has approved Class I Shares which have not been offered publicly. Effective June 15, 2005, the Fund imposed a redemption fee of 2.00% on Class AAA Shares, Class A Shares, Class B Shares, and Class C Shares that are redeemed or exchanged on or before the seventh day after the date of a purchase. (From November 1, 2004 through June 14, 2005, the Fund imposed a redemption fee on shares that were redeemed or exchanged within the sixtieth day after the date of a purchase.) The redemption fee is deducted from the proceeds otherwise payable to the redeeming shareholders and is retained by the Fund. The redemption fees retained by the Fund during the years ended December 31, 2005 and December 31, 2004 amounted to $25,950 and $6,601, respectively. 11 THE GAMCO GROWTH FUND NOTES TO FINANCIAL STATEMENTS (CONTINUED) ================================================================================ The redemption fee does not apply to shares purchased through programs that the Adviser determined to have appropriate short-term trading policies in place. Additionally, certain recordkeepers for qualified and non-qualified retirement plans that could not collect the redemption fee at the participant level due to systems limitations have received an extension to implement such systems. Transactions in shares of beneficial interest were as follows: YEAR ENDED YEAR ENDED DECEMBER 31, 2005 DECEMBER 31, 2004 ---------------------------- ---------------------------- SHARES AMOUNT SHARES AMOUNT ----------- ------------- ----------- ------------- CLASS AAA CLASS AAA ---------------------------- ---------------------------- Shares sold ....................................... 4,243,927 $ 113,064,508 7,724,349 $ 191,537,714 Shares redeemed ...................................

INDEMNIFICATIONS. The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. 10. OTHER MATTERS. The Adviser and/or affiliates have received subpoenas from the Attorney General of the State of New York and the Securities and Exchange Commission (the "SEC") requesting information on mutual fund trading practices involving certain funds managed by the Adviser. GAMCO Investors, Inc., the Adviser's parent company, is responding to these requests for documents and testimony. On a separate matter, in September 2005, the Adviser was informed by the staff of the SEC that the staff may recommend to the Commission that an administrative remedy and a monetary penalty be sought from the Adviser in connection with the actions of two of seven closed-end funds managed by the Adviser relating to Section 19(a) and Rule 19a-1 of the 1940 Act. These provisions require registered investment companies to provide written statements to shareholders when a dividend is made from a source other than net investment income. While the two closed-end funds sent annual statements and provided other materials containing this information, the funds did not send written statements to shareholders with each distribution in 2002 and 2003. The Adviser believes that all of the funds are now in compliance.

These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at December 31, 2005 by correspondence with the custodian, provide a reasonable basis for our opinion.

The Audit Committee ("Committee") of the registrant is responsible for pre-approving (i) all audit and permissible non-audit services to be provided by the independent auditors to the registrant and (ii) all permissible non-audit services to be provided by the independent auditors to the Adviser, Gabelli Funds, LLC, and any affiliate of Gabelli Funds, LLC ("Gabelli") that provides services to the registrant (a "Covered Services Provider") if the independent auditors' engagement related directly to the operations and financial reporting of the registrant. The Committee may delegate its responsibility to pre-approve any such audit and permissible non-audit services to the Chairperson of the Committee, and the Chairperson must report to the Committee, at its next regularly scheduled meeting after the Chairperson's pre-approval of such services, his or her decision(s). The Committee may also establish detailed pre-approval policies and procedures for pre-approval of such services in accordance with applicable laws, including the delegation of some or all of the Committee's pre-approval responsibilities to the other persons (other than Gabelli or the registrant's officers). Pre-approval by the Committee of any permissible non-audit services is not required so long as: (i) the aggregate amount of all such permissible non-audit services provided to the registrant, Gabelli and any Covered Services Provider constitutes not more than 5% of the total amount of revenues paid by the registrant to its independent auditors during the fiscal year in which the permissible non-audit services are provided; (ii) the permissible non-audit services were not recognized by the registrant at the time of the engagement to be non-audit services; and (iii) such services are promptly brought to the attention of the Committee and approved by the Committee or Chairperson prior to the completion of the audit.

(h) The registrant's audit committee of the board of directors has considered whether the provision of non-audit services that were rendered to the registrant's investment adviser (not including any sub-adviser whose role is primarily portfolio management and is subcontracted with or overseen by another investment adviser), and any entity controlling, controlled by, or under common control with the investment adviser that provides ongoing services to the registrant that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X is compatible with maintaining the principal accountant's independence.
