Management Commentary

In our Semi-Annual Report to Shareholders, we asserted that the value of the companies in the Growth Fund had increased while their share prices did not. To follow up on that thesis, it is interesting to note that from January 1, 2005 to December 15, 2005, the earnings of the companies in the Growth Fund portfolio increased approximately 13% more than their stock price. We believe this shows there is appreciation potential in these stocks.

Why has the Fund’s portfolio trailed its benchmark? There are a few reasonable answers. First, our holdings today are predominately larger companies, including Wal-Mart, Viacom, Microsoft, Exxon, First Data and Citigroup. Investors, particularly pension funds and foundations, have looked in the rear view mirror and determined that the returns of large companies have been poor during the last few years and have decided to reallocate over $1 trillion to hedge funds and private equity (LBO) funds. These funds invest predominately in areas other than the large capitalization stocks, and there has not been enough money coming from other sources to offset this change in investment style. According to Morningstar, companies with market values over $100 billion declined an average of 2% in 2005.*

Second, investors appear to be less risk-adverse today: Lower quality investments are selling at premiums to high quality investments.** This is an unusual situation and one which we did not expect. Generally speaking, our investment style attempts to protect principal in tough economic times, but may underperform in periods of rapid economic expansion.

In addition, the Fund owned a number of stocks whose fundamentals disappointed both us and the market. These include Fifth Third Bank, Pfizer, Fannie Mae, the entire “old media” sector and Tyco International. Further, the Fund’s Exxon and Chevron holdings had good appreciation, but less than the smaller oil producers, despite record earnings. Many of these companies are selling at historically low valuations and we believe they have strong likelihoods of turning themselves around.

This year we sold our positions in Hewlett Packard, Office Depot, Paychex and State Street, after very large gains. In their places, we added positions in Disney and eBay and increased our stakes in Wal-Mart and Tyco. Each of these new positions was purchased when we felt the stock was quite depressed and selling at attractive valuations.

As we previously noted, we believe the Fund is positioned to protect principal if the consumer begins to save more and spend less. With a -1.5% savings rate in September,*** a record low, and the $600 billion that consumers have borrowed against their homes this year to fund spending (roughly 7% of consumer spending), it is clear that the theory of “a penny saved is a penny earned” is not in vogue. As interest rates on mortgages and energy prices increase, the housing market begins to level off, and job and wage growth remains relatively modest, we see little likelihood of a strong economy next year. We are beginning to feel like the boy that cried wolf because this process has taken far longer than we envisioned. However, we believe a consistent investment style is in the Fund’s best long term interest.

BOND FUND INVESTMENT REVIEW

November 30, 2005

Portfolio Manager

     John W. Thompson, CFA

Performance

The Thompson Plumb Bond Fund produced a total return of 0.29% for the fiscal year ended November 30, 2005, as compared to 1.63% for its benchmark, the Lehman Brothers Intermediate Government/Credit Index. During 2005, short-term interest rates continued to increase, but yield spreads remained narrow throughout most of the year. This increase in short-term interest rates caused the market value of most of the Bond Fund’s holdings to experience price depreciation.

Management Commentary

The Bond Fund established its investment thesis for 2005 with the expectation that the economy would remain strong and that interest rates would increase as the Federal Reserve tightened monetary policies to combat inflationary pressures from higher energy and commodity costs. During 2005, the Bond Fund maintained a shorter maturity in the portfolio. However, the Bond Fund’s shorter maturity structure had a negative effect on the portfolio as short-term interest rates increased more than long-term rates during the year. The Fund was also negatively impacted by its holdings in Adelphia Communications bonds losing principal due to a declining cable property value.

During 2005, we initiated an investment program to move the composition of the Fund to a mix of higher quality corporate bonds and U.S. Government securities. Because yield spreads are narrow and higher yields are now available on high-quality debt instruments, there is not sufficient return on low-quality bonds to compensate shareholders for the credit risk of lower-quality securities.

We expect that in 2006, short-term interest rates will gradually increase. Also, we expect long-term interest rates to rise moderately over the next couple of years. This will reduce the attractiveness of longer maturity bonds. While the Federal Reserve has increased short-term interest rates thirteen times during the past two years, it is still unclear if those rate increases are sufficient to keep the inflation rate below 2 to 2.5%. Interest rate increases have had the desirable effect of strengthening the dollar and maintaining the flow of foreign investment into this country.

We expect to see the monetary authorities continue to step on the economic brake because the large fiscal stimulus produced by the large Federal budget deficit historically has been the source of inflationary pressures. The scarcity of worldwide energy reserves is likely to keep energy prices high and will add costs to transportation and raw materials, such as chemical feedstocks.

The Thompson Plumb Bond Fund will be positioned in a cautious, conservative mix of bonds until we are able to see an advantage in moving to a more aggressive posture.

Investments in debt securities typically decrease in value when interest rates rise.

FUND EXPENSE EXAMPLES

November 30, 2005

Example

As a shareholder of Thompson Plumb Funds, you incur two types of costs: (1) transaction costs, including redemption fees; and (2) ongoing costs, including management fees and other Fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in a Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period from June 1, 2005 to November 30, 2005.

Actual Expenses

The first line of the table below under each Fund provides information about actual account values and actual expenses for such Fund. 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 entitled “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 below under each Fund provides information about hypothetical account values and hypothetical expenses based on such 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 balances or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in each Fund and other funds. To do so, compare the 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the 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 redemption fees. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

	Beginning		Ending		Expenses Paid During
	Account Value		Account Value		Period*
	06/01/05		11/30/05		06/01/05-11/30/05
Thompson Plumb Growth Fund
Actual	$	1,000.00	$	1,017.74	$	5.51
Hypothetical (5% return before expenses)	$	1,000.00	$	1,019.54	$	5.52
Thompson Plumb Bond Fund
Actual	$	1,000.00	$	992.99	$	4.00
Hypothetical (5% return before expenses)	$	1,000.00	$	1,020.99	$	4.05

* Expenses are equal to the annualized expense ratio for each Fund (Growth Fund: 1.09%; Bond Fund: 0.80%), multiplied by the average account value over the period, multiplied by 183/365 (to reflect the one-half year period).

For more information, please refer to the Funds’ prospectus.

NOTES TO FINANCIAL STATEMENTS

November 30, 2005

NOTE 1 — ORGANIZATION

Thompson Plumb Funds, Inc. (the “Company”) is a Wisconsin corporation registered under the Investment Company Act of 1940, as amended (the “1940 Act”), as an open-end, diversified management investment company.

The Company consists of separate mutual funds series (the “Funds”): Thompson Plumb Growth Fund (the “Growth Fund”) and Thompson Plumb Bond Fund (the “Bond Fund”). The assets and liabilities of each Fund are segregated and a shareholder’s interest is limited to the Fund in which the shareholder owns shares.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies followed by the Funds in the preparation of their financial statements.

SECURITY VALUATION — Each Fund’s investments are valued at their market prices (generally the last reported sales price on the exchange where the securities are primarily traded or, for Nasdaq listed securities, at their Nasdaq Official Closing Prices) or, where market quotations are not readily available or are unreliable, at fair value as determined in good faith pursuant to procedures established by the Funds’ Board of Directors (the “Funds’ Board”). Market quotations for the common stocks in which the Funds invest are nearly always readily available; however, market quotations for debt securities are often not readily available. Fair values of debt securities are typically based on valuations published by an independent pricing service, which uses various valuation methodologies such as matrix pricing and other analytical pricing models as well as market transactions and dealer quotations. Debt securities with remaining maturities of 60 days or less are valued at amortized cost basis.

When a security is “fair valued,” consideration is given to the facts and circumstances relevant to the particular situation, including a review of various factors set forth in the pricing procedures adopted by the Funds’ Board. Fair value pricing is an inherently subjective process, and no single standard exists for determining fair value. Different funds could reasonably arrive at different values for the same security.

SECURITIES TRANSACTIONS AND INVESTMENT INCOME — Investment securities transactions are accounted for on the trade date. Gains or losses realized on sales of securities are determined by comparing the identified cost of the security lot sold with the net sales proceeds. Discounts/premiums on debt securities purchased are accreted/amortized over the life of the respective securities on the same basis for book and tax purposes. Dividend income is recorded on the ex-dividend date. Interest income is recorded as earned.

VARIABLE-RATE DEMAND NOTES — The Funds invest in short-term, variable-rate demand notes, which are unsecured instruments. The Funds may be susceptible to credit risk with respect to these instruments to the extent the issuer defaults on its payment obligation.

PERMANENT BOOK AND TAX DIFFERENCES — Generally accepted accounting principles require that permanent financial reporting and tax differences relating to shareholder distributions be reclassified in the capital accounts.

EXPENSES — Each Fund is charged for those expenses that are directly attributed to it. Expenses that are not readily identifiable to a specific Fund are generally allocated among the Funds in proportion to the relative sizes of the Funds.

USE OF ESTIMATES — The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.

DISTRIBUTIONS TO SHAREHOLDERS — Distributions to shareholders from net investment income and realized gains on securities for the Growth Fund normally are declared on an annual basis. Bond Fund distributions to shareholders from net investment income normally are declared on a quarterly basis, and distributions to shareholders from realized gains on securities normally are declared on an annual basis. Distributions are recorded on the ex-dividend date.

FEDERAL INCOME TAXES — No provision has been made for federal income taxes since the Funds have elected to be taxed as regulated investment companies and intend to distribute substantially all income to shareholders and otherwise comply with the provisions of the Internal Revenue Code applicable to regulated investment companies.

DIRECTED BROKERAGE ARRANGEMENTS — The Funds have directed brokerage arrangements with Fidelity Capital Markets, BNY Brokerage and Trade Manage Capital, Inc. Upon purchase and/or sale of the investment securities at best

17

NOTES TO FINANCIAL STATEMENTS (Continued)

November 30, 2005

execution, the Funds pay brokerage commissions to Fidelity Capital Markets, BNY Brokerage and Trade Manage Capital, Inc. These commission payments generate non-refundable cumulative credits, which are available to pay certain expenses of the Funds. For the year ended November 30, 2005, the Growth Fund expenses were reduced by $60,228 through these direct brokerage credits. These credits reduced the ratio of expenses to average net assets by 0.01% for the Growth Fund for the year ended November 30, 2005.

LINE OF CREDIT — The Funds have established a line of credit (“LOC”) with U.S. Bank N.A. which expires November 15, 2006, used for temporary liquidity needs. The LOC is used primarily to finance redemption payments. Each of the individual Funds borrowing under the LOC are limited to either 5% of the market value of the Fund’s total assets or any explicit borrowing limits imposed by the Board, whatever is less. As of November 30, 2005, the limits established by the Board are: Growth Fund — $20,000,000 and Bond Fund — $1,000,000. The LOC was drawn upon during the year; however, as of November 30, 2005, there were no borrowings by the Funds outstanding under the LOC. The following table shows the average balance, average interest rate and interest expense incurred by the Funds on borrowings under the LOC for the year ended November 30, 2005.

	Average		Average			Interest
Fund	Balance		Interest Rate			Expense
Growth Fund	$	1,108,685		6.06	%	$	66,865

GUARANTEES AND INDEMNIFICATIONS — In the normal course of business, the Funds enter into contracts with service providers that contain general indemnification clauses. The Funds’ maximum exposure under these arrangements is unknown as this would involve future claims against the Funds that have not yet occurred. Based on experience, the Funds expect the risk of loss to be remote.

NOTE 3 — INVESTMENT ADVISORY AND ADMINISTRATIVE AND ACCOUNTING SERVICES AGREEMENTS AND OTHER TRANSACTIONS WITH AFFILIATES

The Investment Advisory Agreement pursuant to which Thompson Investment Management LLC (“TIM”) is retained by the Funds provides for compensation to TIM (computed daily and paid monthly) at the following annual rates: for the Growth Fund — 1.00% of the first $50 million of average daily net assets, and 0.90% of average daily net assets in excess of $50 million; and for the Bond Fund — 0.65% of the first $50 million of average daily net assets, and 0.60% of average daily net assets in excess of $50 million.

Pursuant to an Administrative and Accounting Services Agreement, TIM Holdings, Inc., (an affiliate of TIM) maintains the Funds’ financial records in accordance with the 1940 Act, prepares all necessary financial statements of the Funds and calculates the net asset value per share of the Funds on a daily basis. As compensation for its services, each Fund pays TIM Holdings, Inc. a fee computed daily and payable monthly at the annual rate of 0.15% of net assets up to $30 million, 0.10% of the next $70 million of net assets, and 0.025% of net assets in excess of $100 million, with an annual minimum fee of $30,000 per Fund. The calculations of daily net asset value are subcontracted to U.S. Bancorp Fund Services, resulting in fees paid by TIM Holdings, Inc. in the amounts of $123,823 and $30,000, for the Growth Fund and Bond Fund, respectively for the year ended November 30, 2005.

The Advisor is contractually bound to waive management fees and/or reimburse expenses incurred by the Bond Fund through March 31, 2006 so that the annual operating expenses of the Bond Fund do not exceed 0.80% of average daily net assets.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of Thompson Plumb Funds, Inc.

In our opinion, the accompanying statements of assets and liabilities, including the schedules of investments, and the related statements of operations and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of Thompson Plumb Growth Fund and Thompson Plumb Bond Fund (constituting the Thompson Plumb Funds, Inc., hereafter referred to as the “Funds”) at November 30, 2005, and the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as “financial statements”) are the responsibility of the Funds’ 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 auditing standards generally accepted in the United States of America, which 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 November 30, 2005 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

Board Approval of Investment Advisory Agreement

The Investment Company Act of 1940, as amended, requires that the annual renewal of the advisory agreements be approved by the vote of a majority of the Board of Directors who are not parties to the advisory agreements or “interested persons” of the investment company (as that term is defined in the Investment Company Act of 1940) (the “Independent Directors”), cast in person at a meeting called for the purposes of voting on such approval. At its meeting held November 14, 2005, the Independent Directors of the Thompson Plumb Funds, Inc. (“Thompson Plumb”) approved the investment advisory agreement (the “Advisory Agreement”) between Thompson Plumb and Thompson Investment Management LLC (the “Advisor”) with respect to the Thompson Plumb Growth Fund and Thompson Plumb Bond Fund (the ”Funds”).

The Directors’ approval was based on their consideration and evaluation of a variety of factors, including: (1) the nature, extent and quality of the services provided by the Advisor; (2) the performance of each Fund in comparison to a peer group of mutual funds; (3) the management fees and the total operating expenses of each Fund, including comparative information with respect to a peer group of mutual funds; (4) the profitability of the Advisor; and (5) the extent to which economies of scale may be realized as each Fund grows.

To facilitate the evaluation of the foregoing factors for the Advisory Agreement, the Advisor provided various materials and information to the Board, including:

• A memo from the Advisor recommending that the Board approve the Advisory Agreement, outlining information regarding the services provided by the Advisor, describing the Advisor’s investment philosophy, providing the biographies of the portfolio managers for the Funds, explaining any significant changes in the Advisor that occurred during the last year, describing the facilities and systems used by the Advisor to provide management services, outlining Fund sales and redemptions during the last year, explaining Fund performance, describing management fees, and explaining the Advisor’s profitability;

• A copy of the Advisory Agreement dated January 16, 2004, between Thompson Plumb, on behalf of the Growth and Bond Funds, and the Advisor;

• A copy of the Advisor’s current Form ADV;

26

ADDITIONAL INFORMATION(Continued)

• A Section 15(c) Report prepared by Lipper, Inc. comparing the expenses and performance of the Funds against peer groups and standardized indices; and

• A memorandum from legal counsel to the Directors, which outlined the duties and responsibilities of the Directors in connection with approval of investment advisory agreements and summarized relevant case law on this issue.

Throughout the review and approval process, the Independent Directors were represented by independent legal counsel.

After reviewing and discussing this information, and taking into account other information routinely provided to the Board at its regular quarterly meetings throughout the year regarding the quality of the services provided by the Advisor, including investment management, portfolio trading and compliance functions, the performance of the Funds, regulatory compliance issues and related matters, the Independent Directors concluded that:

• The management fees paid to the Advisor are comparable to those paid by other funds in Thompson Plumb’s peer group. Although the Growth Fund’s management fee is slightly higher than the median of its peer group, the Board found the fee to be reasonable in light of the services provided. Based on this comparison and a review of the factors described above, the Board found the management fees to be fair and reasonable.

• The nature, extent and quality of the services provided by the Advisor are appropriate for the investment objectives and programs of each of the Funds and are acceptable. The Advisor has appropriate and sufficient knowledge and experience in order to manage the Funds. In particular, the Board concluded that the Advisor employs experienced personnel and obtains necessary resources in order to properly manage the Funds and obtains additional personnel and resources when necessary. In addition, the Advisor is committed to the proper management and success of the Funds;

• The investment performance of the Growth and Bond Funds have been acceptable as measured by relative performance and in comparison to the performance of funds in their peer groups. Although the recent performance of the Growth Fund has been lagging, the long-term performance for both Funds has been acceptable;

• The total expenses of the Funds, including expenses waivers for the Bond Fund, are reasonable;

• The level of profitability realized by the Advisor from its services to the Funds are reasonable based on a comparison of the profitability of a group of other mutual fund advisors and in comparison to the profitability of services provided by the Advisor to separately managed clients; and

• The breakpoints that exist for the Funds are reasonable. At this time, the Funds’ breakpoints provide for a fair sharing of any economies of scale that may be realized as the Funds’ assets grow. However, the Board decided to review this matter at such time as the Fund’s assets significantly increase.

The Board compared the management fees paid by the Funds with the schedule of fees charged by the Advisor to other institutional accounts, as disclosed in its Form ADV, and concluded that the management fees were reasonable in consideration of the level of services provided to the Funds.

Based on the factors and conclusions discussed above, the Board, including all of the Independent Directors, approved the Advisory Agreement.
