REPORT TO STOCKHOLDERS. {LOGO} IRONWOOD FUNDS IRONWOOD SERIES TRUST ------------------------- IRONWOOD ISABELLE SMALL COMPANY STOCK FUND Semi-Annual Report June 30, 2006 IRONWOOD ISABELLE SMALL COMPANY STOCK FUND TABLE OF CONTENTS SHAREHOLDER LETTER ........................................................ 2 PORTFOLIO OF INVESTMENTS .................................................. 7 STATEMENT OF ASSETS AND LIABILITIES ....................................... 10 STATEMENT OF OPERATIONS ................................................... 11 STATEMENTS OF CHANGES IN NET ASSETS ....................................... 12 FINANCIAL HIGHLIGHTS ...................................................... 14 NOTES TO FINANCIAL STATEMENTS ............................................. 18 IRONWOOD ISABELLE SMALL COMPANY STOCK FUND SHAREHOLDER LETTER To our Valued Shareholders: My letter to you this period will be relatively short and hopefully to the point. After what, in our view, was a stellar first quarter, the small cap markets almost immediately faced a blizzard of conflicting macro factors, the uncertainty of which caused a near full about face in performance. After gaining some 13.93% through the end of March, the Russell 2000 Index, which is the Ironwood Isabelle Small Company Stock Fund's (the "Fund") benchmark, declined 5.02% through the end of June and at this writing in mid-August, has given back nearly all of its gains for the year to date. Despite our emphatic assertions that the research process is indeed working and that your portfolio remains well-constructed for the future, these difficult times have had an adverse effect on Fund performance, as well. The Fund's Investment Shares declined by 9.09% for the quarter, lagging the benchmark, though still out performing it for the six month period ended June 30 at 8.70%, versus 8.21% for the benchmark. We have written extensively over the past two years about our efforts at intensifying the research effort and focusing the portfolio. I will not harp on that subject again, as we believe the process is working as it should, and will continue to benefit the Fund over the long term. That said, some discussion as to why the Fund underperformed during the last quarter is in order. What we want here is to help you understand what we believe occurs during periods of market instability and how we react, or do not react, in those situations. We can analyze and rationally address a change in fundamentals for a given company. For example, if we can determine that a company's fortunes are about to turn down, we would expect its economic fundamentals to decline as well, which would most likely not bode well for the stock price of the company, prompting us to sell out of the position ahead of the turmoil. What we cannot well address, especially in the short run, is the excess downward price movement created in small cap stocks resulting from fear or uncertainty which destroys investor confidence. Once again the threat of war, terrorism, runaway energy prices, and inflation, appeared to have all contributed to just such a change in sentiment in the 2nd quarter. During these periods, when relative safety is sought, entire sectors of the market can be 2 abandoned without regard to company fundamentals. Moreover, in our experience, small cap stocks tend to suffer disproportionately to their size and relative liquidity in such circumstances. During the second quarter, as these uncertainties became increasingly visible, your Fund's portfolio, from a market sense, reacted accordingly. Small caps were hit the hardest of all stock groups, and the fact that the portfolio includes a number of smaller, less liquid names, and is involved in some economic sectors such as biotechnology and basic industries that for a period of time have been abandoned by investors, are in our judgment why the Fund underperformed the far more broad Russell 2000 Index for the period. What to do? As we have said in the past, with proper research and investment thesis intact, for a given stock, we believe the thing to do is sit tight. We are long-term investors. We are always looking for new ideas and if because of those same difficult market conditions, we can find a company that is a victim of an overreaction such that the long term value proposition appears to us better than for one of our existing holdings, we will make a change, but only if our analysis and valuation warrant it. Despite the turbulence, during the quarter, there was activity in the Fund's portfolio. We exited five positions, while making four new investments. Two of the five sales, corporate travel consultant Navigant International (NASDAQ: FLYR) and apparel manufacturer Russell Corp (NYSE: RUS), were precipitated by merger activity, and though the buy out prices in both cases were less than we would have liked, a respectable return was made in each. Sterling Construction (NASDAQ: STRL went from what, in our judgment, was a quite undervalued to a clearly overvalued stock within six months, producing a nice gain (50%+) in the process. Neopharm (NASDAQ: NEOL) was one biotechnology instance where we decided to take advantage of the adverse market conditions, at least from a tax-loss perspective, recognizing that significant clinical trials news on the company's promising treatment for brain cancer would not be forthcoming for several months at best. Finally, Hudson Highland Group (NASDAQ: HHGP), a provider of temporary and permanent professional staffing, was both a new purchase and a sale in the quarter. While the potential for this company might have been tremendous, it quickly became apparent to us that the change in environment we were expecting was not developing, but actually becoming worse. 3 The new additions to the portfolio are faring better, as we would expect. The largest of these, Bausch and Lomb (NYSE: BOL) is well known as a provider of eye care products. The news that its ReNu with MoistureLoc contact lens cleaner poses a higher risk for a potentially blinding fungal infection caused shares to fall by more than 40%, and is precisely why we are invested in the company, as we believe that those fears were largely overdone and the company has acted responsibly by removing it from distribution. NovaGold (NYSE:NG) is a precious metals mining company that to us represents a bargain. Its gold reserves are valued at just $40 per ounce, by far the lowest of any significant developer in North America, and a mere fraction of the $600+ per ounce for gold sold on the spot market. Finally, we have reinitiated a position in smart-card developer and security software provider Actividentity (NASDAQ: ACTI), formerly called Activcard. This firm struggled to execute on its strategy, but the new CEO, Jason Hart, seems to have put his house in order, underscoring his conviction with repeated large purchases of stock. With second half of the year upon us, we reiterate that despite added near-term volatility, which we appreciated in the first quarter but loathed in the second, we are comfortable with the construction of the Fund's portfolio and the process responsible for building it. With those thoughts in mind but cognizant of the near-term uncertainties that could pose continued problems ahead, we remain confident in the capability of your Fund to deliver satisfactory results.

The Trust is registered under the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund offers two classes of shares, Investment Shares and Institutional Shares (collectively, the "Shares"), each of which has equal rights as to class and voting privileges. The Investment Shares have exclusive voting rights with respect to its distribution plan pursuant to Rule 12b-1 under the 1940 Act ("12b-1 Plan") and are subject to 12b-1 Plan expenses. The Fund commenced operations on March 9, 1998 (March 27, 1998 for the Institutional Shares). The investment objective of the Fund is to seek capital appreciation by investing primarily in relatively undervalued common stocks of domestic small companies. The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The policies are in conformity with accounting principles generally accepted in the United States of America for investment companies. A. SECURITY VALUATION. Exchange traded securities and over-the-counter securities listed on the NASDAQ National Market System for which market quotations are readily available are valued using the last reported sales price or the NASDAQ Official Closing Price ("NOCP"), provided by independent pricing services as of the close of trading on the New York Stock Exchange (normally 4:00 p.m. Eastern time), on each Fund business day. In the absence of a sale or NOCP, such securities are valued at the mean of the last bid and asked price. Non-exchange traded securities for which quotations are available are generally valued at the mean between the current bid and asked prices. Debt securities may be valued at prices supplied by the Fund's pricing agent based on broker or dealer supplied valuations or matrix pricing, a method of valuing securities by reference to the 18 IRONWOOD ISABELLE SMALL COMPANY STOCK FUND NOTES TO FINANCIAL STATEMENTS JUNE 30, 2006 - (Unaudited), (Continued) value of other securities with similar characteristics, such as rating, interest rate and maturity. Money market instruments that mature in sixty days or less may be valued at amortized cost. The Fund values securities at fair value pursuant to procedures adopted by the Trust's Board of Trustees (the "Board") if (1) market quotations are insufficient or not readily available; or (2) the Adviser believes that the prices or values available are unreliable. Fair valuation is based on subjective factors and as a result, the fair value price of an asset may differ from the asset's market price and may not be the price at which the asset may be sold. Fair valuation could result in a different net asset value ("NAV") than a NAV determined by using market quotes. B. INVESTMENT INCOME AND SECURITIES TRANSACTIONS. Securities transactions are accounted for on the date the securities are purchased or sold (trade date). Cost is determined and gains and losses are based on the identified cost basis for both financial statement and federal income tax purposes. Dividend income is reported on the ex-dividend date. Interest income and expenses are accrued daily. C. NET ASSET VALUE PER SHARE. Net Asset value per share of each class of shares of the Fund is determined daily as of the close of trading on the New York Stock Exchange by dividing the value of the total assets, less liabilities attributable to that class, by the number of outstanding shares of that class. The net asset value of the classes may differ because of different fees and expenses charged to each class. D. FEDERAL INCOME TAXES. The Trust intends to continue to qualify each year as a regulated investment company by complying with all requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies including, among other things, distributing substantially all of its earnings to its shareholders. Therefore, no federal income tax provision is required. The characterization of distributions to shareholders for financial reporting purposes is determined in accordance with federal income tax rules. 19 IRONWOOD ISABELLE SMALL COMPANY STOCK FUND NOTES TO FINANCIAL STATEMENTS JUNE 30, 2006 - (Unaudited), (Continued) For the year ended December 31, 2005, the Fund reclassified $967,078 to decrease accumulated net realized gain and $967,078 to increase accumulated net investment loss. The reclassification has no impact on the net asset value of the Fund and is primarily due to net operating losses. As of December 31, 2005, distributable earnings on a tax basis were as follows: Undistributed Ordinary Income $ 396,919 Undistributed Long-Term Gain 1,790,685 Unrealized Appreciation (Depreciation) 15,743,489 ------------- Total $ 17,931,093 ============= E. INCOME AND EXPENSES. Expenses directly attributable to a particular class are charged directly to such class. In calculating 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 on the proportion of net assets of each class at the beginning of that day. F. REPURCHASE AGREEMENTS. The Fund may invest in repurchase agreements. The Fund will require the financial institution with which the Fund enters into a repurchase agreement to maintain collateral at all times with a value equal to the amount the Fund paid for the securities. In the event of default, the Fund may have difficulties disposing of such securities. G. DISTRIBUTIONS TO SHAREHOLDERS. The Fund will distribute substantially all of its net investment income and capital gains, if any, at least annually. Distributions to shareholders are recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States of America. 20 IRONWOOD ISABELLE SMALL COMPANY STOCK FUND NOTES TO FINANCIAL STATEMENTS JUNE 30, 2006 - (Unaudited), (Continued) H. NEW ACCOUNTING PRONOUNCEMENTS. In June 2006, the Financial Accounting Standards Board issued Financial Interpretation No. 48, "Accounting for Uncertainty in Income Taxes" (the "Interpretation"), which is effective for fiscal years beginning after December 15, 2006 and is to be applied to all open tax years as of the effective date. This Interpretation prescribes a minimum threshold for financial statement recognition of the benefit of a tax position taken or expected to be taken in a tax return, and requires certain expanded disclosures. Management has recently begun to evaluate the application of the Interpretation to the Fund, and has not at this time determined the impact, if any, resulting from the adoption of this Interpretation on the Fund's financial statements. I. USE OF ESTIMATES. In preparing financial statements in conformity with generally accepted accounting principles, management makes estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. NOTE 2 - PURCHASES AND SALES OF SECURITIES Purchases and sales of securities, other than short-term investments, aggregated $67,655,950 and $41,721,909, respectively, for the six months ended June 30, 2006. NOTE 3 - ADVISORY FEES, SERVICING FEES, AND OTHER TRANSACTIONS WITH RELATED PARTIES INVESTMENT ADVISER - Ironwood Investment Management, LLC (formerly known as Ironwood Capital Management) ("Ironwood") serves as the investment adviser for the Fund pursuant to an investment advisory agreement (the "Agreement"). Under the terms of the Agreement, Ironwood receives an investment advisory fee from the Fund, accrued daily and paid monthly, at an annual rate of 1.00% of the average daily net assets of the Fund. Pursuant to the terms of the 21 IRONWOOD ISABELLE SMALL COMPANY STOCK FUND NOTES TO FINANCIAL STATEMENTS JUNE 30, 2006 - (Unaudited), (Continued) Agreement, Ironwood is obligated for as long as the Agreement remains in effect, to limit total annual Fund operating expenses, including its investment advisory fee, to 1.95% of the average daily net assets annually for the Investment Shares and 1.70% of the average daily net assets annually for the Institutional Shares, and to waive such fees and reimburse expenses to the extent that they exceed these amounts. For the six months ended June 30, 2006, advisory fees of $3,402 were waived by Ironwood. INVESTMENT ADVISORY CONTRACT APPROVAL - On January 24, 2006, Ironwood consummated a transaction (the "Transaction") with MB Investment Partners, Inc. and MB Investment Partners and Associates LLC ("MBIPA"), pursuant to which MBIPA acquired Ironwood. The Transaction resulted in a change in control of Ironwood and an assignment and automatic termination of the Investment Advisory Agreement between Ironwood and the Trust, on behalf of the Fund (the "Agreement"), pursuant to the terms of the Agreement. On October 17, 2005, the Trust's Board of Trustees (the "Board") approved an Interim Investment Advisory Agreement between the Trust, on behalf of the Fund, and Ironwood (the "Interim Agreement"). The Interim Agreement became effective upon closing of the Transaction and remained in effect until April 18, 2006, at which time the Fund's shareholders approved, at a special meeting, a new investment advisory agreement (the "New Agreement," and, collectively with the Interim Agreement and the Agreement, the "Advisory Agreements") between Ironwood and the Trust, on behalf of the Fund, also approved by the Board on October 17, 2005. The terms, including without limitation the advisory fee, of each of the Advisory Agreements, are the same in all material respects, except with respect to those terms related to duration of each Advisory Agreement, and execution and termination dates. The basis of the Board's approval of both the Interim Agreement and New Agreement is set forth in the Fund's Annual Report dated December 31, 2005. 22 IRONWOOD ISABELLE SMALL COMPANY STOCK FUND NOTES TO FINANCIAL STATEMENTS JUNE 30, 2006 - (Unaudited), (Continued) ADMINISTRATION AND OTHER SERVICES - Citigroup Fund Services, LLC, through its various affiliates ("Citigroup"), provides administration, portfolio accounting and transfer agency services to the Fund. In addition, the Fund has entered into separate service and operating agreements with Charles Schwab & Co., Inc. ("Schwab") and Fidelity Capital Markets ("FCM"), whereby Schwab and FCM make shares of the Fund available to their clients in exchange for a servicing fee. These fees are included as part of the Transfer Agency fees on the statement of operations. For the six months ended June 30, 2006, the Fund was reimbursed expenses of $39,457 by FCM. The custodian, Fifth Third Bank (the "Custodian"), has agreed to compensate the Fund and decrease custody fees for interest on any cash balances left uninvested. For the six months ended June 30, 2006, the Fund was reimbursed expenses of $607 by the Custodian. DISTRIBUTOR - Foreside Fund Services, LLC is the Fund's distributor (the "Distributor). The Distributor is not affiliated with the Adviser or Citigroup or its various affiliates. The Distributor receives no compensation from the Fund for its distribution services. Under a Compliance Services Agreement with the Trust, the Distributor provides a Chief Compliance Officer to the Trust as well as certain additional compliance support functions. No trustee, officer or employee of Ironwood, or Citigroup, or any affiliate thereof, receives any compensation from the Trust for serving as a Trustee or officer of the Trust. NOTE 4 - LINE OF CREDIT The Fund has entered into a line of credit agreement with the Custodian to be used for temporary purposes, primarily for financing redemptions. The agreement provides that the Fund may borrow up to $5,000,000. The aggregate outstanding principal amount of all loans may not exceed $5,000,000. Interest is charged to the Fund, based on its borrowings, at a 23 IRONWOOD ISABELLE SMALL COMPANY STOCK FUND NOTES TO FINANCIAL STATEMENTS JUNE 30, 2006 - (Unaudited), (Continued) rate equal to the rate of interest on overnight facilities which the Custodian is offering to other borrowers and potential borrowers of comparable financial condition on the business day that a loan is made pursuant to the agreement. During the six months ended June 30, 2006, the Fund was charged $150 from borrowings under the line of credit. As of June 30, 2006, the Fund had no loans outstanding under the line of credit. NOTE 5 - DISTRIBUTION PLAN The Trustees of the Fund have adopted a 12b-1 Plan with respect to the Investment Shares pursuant to Section 12(b) of the 1940 Act and Rule 12b-1 thereunder, which permits the Fund to pay certain expenses associated with the distribution of its Investment Shares. Under the 12b-1 Plan, the Fund compensates the Distributor, at a fee calculated at an annual rate of up to 0.25% of the value of the average annual net assets attributable to the Investment Shares for distribution expenses borne, or paid to others, by the Distributor. For the six months ended June 30, 2006, the Fund incurred $94,078 in distribution costs for Investment Shares. NOTE 6 - PAYMENTS BY AFFILIATE & OTHER SERVICE PROVIDER For the year ended December 31, 2005, Citigroup reimbursed the Fund to offset an accounting error. As a result, the Fund reimbursed the shareholders who placed trades during the re-evaluation period. In order to compensate the Fund for the overstated number of shares issued to subscribing shareholders during the reevaluation period, Citigroup reimbursed the Fund for the dollar value of these shares. This amount is reflected as payment by other service provider on the Statements of Changes in Net Assets. This payment had no effect on the total return of the Fund. 24 IRONWOOD ISABELLE SMALL COMPANY STOCK FUND NOTES TO FINANCIAL STATEMENTS JUNE 30, 2006 - (Unaudited), (Continued) NOTE 7 - PROXY VOTING INFORMATION A description of the policies and procedures that the Fund uses to determine how to vote proxies relating to securities held in the Fund's portfolio is available, without charge and upon request, by calling (800) 472-6114 and on the SEC's website at www.sec.gov. The Fund's proxy voting record for the twelve-month period ended June 30, is available, without charge and upon request, by calling (800) 472-6114, on the Fund's website www.ironwoodfunds.com and on the SEC's website at www.sec.gov. NOTE 8 - AVAILABILITY OF QUARTERLY PORTFOLIO SCHEDULES The Fund files its complete schedule of portfolio holdings with the SEC for the first and third quarters of each fiscal year on Form N-Q. The Fund's Forms N-Q are available, without charge and upon request, on the SEC's website at www.sec.gov. or may be reviewed and copied at the SEC's Public Reference Room in Washington, D.C. Information on the operation of the Public Reference Room may be obtained by calling (800) SEC-0330. NOTE 9 - SHAREHOLDER EXPENSES As a shareholder of the Fund, you incur ongoing costs, including management fees and distribution fees with respect to Investment Shares and other Fund expenses. This example is intended to help you understand these costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The following example is based on $1,000 invested at the beginning of the period and held for the entire period from January 1, 2006 through June 30, 2006. 25 IRONWOOD ISABELLE SMALL COMPANY STOCK FUND NOTES TO FINANCIAL STATEMENTS JUNE 30, 2006 - (Unaudited), (Continued) ACTUAL EXPENSES - The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. 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 in the first line under the heading "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES - The second line of the table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing cost of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of other funds. Please note that expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs. 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. In addition, if these transactional costs had been included, your costs would have been higher. 26 IRONWOOD ISABELLE SMALL COMPANY STOCK FUND NOTES TO FINANCIAL STATEMENTS JUNE 30, 2006 - (Unaudited), (Continued) BEGINNING ENDING EXPENSES ACCOUNT VALUE ACCOUNT VALUE PAID DURING JANUARY 1, 2006 JUNE 30, 2006 PERIOD* --------------- ------------- ------- INVESTMENT SHARES Actual $ 1,000.00 $ 1,086.95 $ 9.73 Return Hypothetical Return $ 1,000.00 $ 1,015.47 $ 9.39 INSTITUTIONAL SHARES Actual $ 1,000.00 $ 1,089.24 $ 8.75 Return Hypothetical Return $ 1,000.00 $ 1,016.41 $ 8.45 - ---------------- * Expenses are equal to the Fund's annualized expense ratios of 1.88% and 1.69% for Investment Shares and Institutional Shares, respectively, multiplied by the average account value over the period, multiplied by the number of days in most recent fiscal half-year/365 (to reflect the half-year period).
