Fourth Quarter Results

With the possibility of a "double dip" recession, together with various concerns regarding the European debt crises showing signs of diminishing, investor confidence returned to lead the stock market to a significant fourth quarter recovery. The Growth Fund fully participated in this turnaround, showing a total investment return of 13.5%, which compared favorably with fourth quarter returns of 12.8% for the Dow Jones Industrial Average and 11.8% for the benchmark Standard & Poor's 500 Index. A peer group universe of similar multi-cap core funds shown in the Wall Street Journal experienced a lesser 10.8% average return.

Recently reported fourth quarter Gross Domestic Product figures showed an improved 2.8% gain (preliminary basis) although inventory spending accounted for a significant portion of the gain. Consumer spending showed an encouraging 2.0% increase along with a 4.7% boost in exports. Government spending continued to be a drag on the economy, experiencing a 4.6% rate of decline. Inflation remained well contained with government figures showing only a modest 0.7% rise in a price index for personal consumption expenditures. Corporate profits continued to increase with a better than expected "high single digit" rate indicated by reported results for S&P 500 companies.

With inflation seemingly well under control, the Federal Reserve has continued to aggressively pursue a stimulative monetary policy in an attempt to "jump start" the economy. As a result, interest rates at both the short and long end of the rate curve have remained at historically low levels during the quarter. Moreover, credit spreads have also generally narrowed because of a shortage of new financing supply.

The strength in the stock market during the final quarter reflected a growing level of confidence in future earnings growth along with historically low interest rates and reasonable valuation levels. This combination of factors resulted in a willingness on the part of investors to take on more risk by buying issues more cyclical in nature as well as issues of more volatile small-cap companies. Conversely, the more stable, lower risk issues in sectors such as consumer staples, health care and utilities underperformed by comparison. Among individual holdings in the Fund, Stratasys (+64.0%), SurModics (+61.1%), MTS Systems (+33.0%), Fastenal (+31.0%) and H. B. Fuller (+26.8%) performed the best, while Baxter Int'l (-11.9%), NVE Corp. (-8.5%), St. Jude Medical (-5.2%), Zimmer Holdings (-0.1%) and Techne (+0.4%) fared the worst.

TO OUR SHAREHOLDERS (continued)

2011 in Review

Over the past year, the stock market was characterized by high volatility with alternating periods of both strength and weakness, depending on changing investor perceptions of the European financial crisis and its effect on the U. S. economy. The Growth Fund ended the year with a modestly positive investment return of 0.7% compared to higher returns of 8.4% for the DJIA and 2.1% for the benchmark S&P 500. However, the Fund performed somewhat better than most of its peers, as shown by an average negative return of -2.7% for a universe of comparable multi-cap core funds in the Wall Street Journal.

Even though the economy showed some pick-up in the fourth quarter, the year as a whole proved to be quite disappointing with only a 1.7% (preliminary basis) rate of growth. This represented a slippage from a 3.0% rate of growth in 2010. Like the fourth quarter, most of the full year strength came from consumer spending and export growth partially offset by a weakness in government spending. Corporate profits are believed to have again increased at a "double digit " rate similar to the previous year, in response to such factors as continuing productivity improvement, higher foreign profits and currency translation gains.

Future Outlook

While some of the fourth quarter economic strength seems likely to spillover into 2012, the outlook for the full year appears anything but clear. Such factors as the presidential election, continuing uncertainties in Europe and rising tensions in the Middle East should all serve to temper one's optimism for the coming twelve month period. Moreover, historically high debt levels will continue to restrain government spending again during the coming year and beyond. On the other hand, prospects for consumer spending may be somewhat brighter if the employment situation continues to improve. In addition, any improvement in the long-depressed housing picture could increase confidence and further help the outlook for consumer spending. However, even with an improved outlook for consumer spending, it seems difficult to build a case for economic growth much beyond 2% over the foreseeable future, barring a major change in the outlook for such issues as taxes, health care costs and the trend in government regulation.

The outlook for corporate profit growth seems likely to be somewhat better than that for the overall economy in light of such factors as cost cutting, productivity improvement programs and participation in faster growing foreign markets. Also, earnings on a per share basis should continue to benefit from significant corporate buyback programs arising from record cash flow and balance sheet liquidity.

TO OUR SHAREHOLDERS (continued)

Because of such factors as election year politics, a low rate of inflation and slow economic growth, the Federal Reserve seems unlikely to change its very stimulative monetary policy any time soon, resulting in a continuation of historically low interest rate levels. In fact, the Fed has recently suggested that its accommodative policy could remain in place for as long as two or more years. This seems to imply that the Fed is also looking for a period of continuing below normal growth over the immediate future.

Finally, prospects for the stock market appear to be somewhat better than the overall outlook for the U. S. economy. Because of relatively low valuation levels (13x estimated 2012 earnings for the S&P 500) along with historically low interest rates, the stock market seems to be already discounting many of the challenges now facing the economy. In addition, relatively high and rising dividend yields continue to make stocks look more attractive relative to fixed income investment alternatives.

NOTES TO FINANCIAL STATEMENTS December 31, 2011

Note 1 – Organization and Significant Accounting Policies

The Mairs and Power Growth Fund, Inc. (the Fund) is registered under the Investment Company Act of 1940 (as amended) as a diversified, no-load, open-end management investment company. The objective of the Fund is to provide shareholders with a diversified portfolio of common stocks, which have the potential for above-average, long-term appreciation. Effective January 1, 2012, the Fund completed a reorganization into a newly formed series of the Mairs and Power Funds Trust, a Delaware statutory trust (the Trust), which is known as the Mairs and Power Growth Fund series of the Trust.

Significant accounting policies of the Fund are as follows:

Security Valuations

Security valuations for Fund investments are furnished by independent pricing services that have been approved by the Fund's Board of Directors (the Board). Investments in equity securities are valued at the NASDAQ Official Closing Price if readily available for such securities on each business day. Other equity securities traded in the over-the-counter market and listed equity securities for which no sale was reported on that date are stated at the last quoted bid price. Debt obligations with 60 days or less remaining until maturity may be valued at their amortized cost, which approximates fair value.

Securities for which prices are not available from an independent pricing service, but where an active market exists, are valued using market quotations obtained from one or more dealers that make markets in the securities or from a widely used quotation system. When market quotations are not readily available, or where the last quoted sale price is not considered representative of the value of the security if it were to be sold on that day, the security will be valued at fair value as determined in good faith by the Fair Value Committee appointed by the Board, pursuant to procedures approved by the Board. Factors that may be considered in determining the fair value of a security are fundamental analytical data relating to the security, the nature and duration of any restrictions on the disposition of the security, and the forces influencing the market in which the security is purchased or sold. As of December 31, 2011, no securities in the Fund were valued using this method.

Fair Valuation Measurements

The Fund has adopted authoritative fair valuation accounting standards which establish a definition of fair value and set out a hierarchy for measuring fair value. These standards require additional disclosures about the various inputs and valuation techniques used to develop the

NOTES TO FINANCIAL STATEMENTS (continued) December 31, 2011

Note 1 – Organization and Significant Accounting Policies (continued)

measurements of fair value and changes in valuation techniques and related inputs during the period. These inputs are summarized in the three broad levels listed below:

• Level 1 – Quoted prices in active markets for identical securities.

• Level 2 – Other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.).

• Level 3 – Significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments).

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. All of the inputs used to value the Fund's investments as of December 31, 2011 were classified as Level 1. For detail of investments by major industry classification, please refer to the Schedule of Investments. There were no transfers between levels during the period. The Fund did not hold any Level 3 investments at either December 31, 2011 or December 31, 2010, therefore, a rollforward of Level 3 investments is not required.

On May 12, 2011, the Financial Accounting Standards Board (FASB) issued an Accounting Standard Update (ASU) No. 2011-04 modifying FASB Accounting Standards Codification (ASC) Topic 820, Fair Value Measurements and Disclosures. At the same time, the International Accounting Standards Board (IASB) issued International Financial Reporting Standard (IFRS) 13, Fair Value Measurement. The objective by the FASB and IASB is convergence of their guidance on fair value measurements and disclosures. Specifically, the ASU requires reporting entities to disclose i) the amounts of any transfers between Level 1 and Level 2, and the reasons for the transfers, ii) for Level 3 fair value measurements, a) quantitative information about significant unobservable inputs used, b) a description of the valuation processes used by the reporting entity and c) a narrative description of the sensitivity of the fair value measurement to changes in unobservable inputs if a change in those inputs might result in a significantly higher or lower fair value measurement. The effective date of the ASU is for interim and annual periods beginning after December 15, 2011. At this time, management is evaluating the implications of this guidance and the impact it will have on the financial statement amounts and footnote disclosures, if any.

Security Transactions and Investment Income

Security transactions are recorded on the date on which securities are purchased or sold. Dividend income and corporate action transactions are recorded on the ex-dividend date and

NOTES TO FINANCIAL STATEMENTS (continued) December 31, 2011

Note 1 – Organization and Significant Accounting Policies (continued)

interest income is recorded on an accrual basis. Realized gains and losses are reported on an identified cost basis.

Income Taxes

The Fund is a "regulated investment company" as defined in Subtitle A, Chapter 1, Subchapter M of the Internal Revenue Code (the Code), as amended. No provision has been made for federal income taxes as it is the intention of the Fund to comply with the provisions of the Code applicable to regulated investment companies and to make distributions of income and realized gains sufficient to relieve it from all or substantially all excise and income taxes.

As of December 31, 2011, the Fund did not have any tax positions that did not meet the "more-likely-than-not" threshold of being sustained by the applicable tax authority. Generally, tax authorities can examine all tax returns filed for the last three years.

On December 22, 2010, the Regulated Investment Company Modernization Act of 2010 (the Act) was enacted, which changed various technical rules governing the tax treatment of regulated investment companies. The changes are generally effective for taxable years beginning after the date of enactment. One of the more prominent changes addresses capital loss carryforwards. Under the Act, the Fund will be permitted to carry forward capital losses incurred in taxable years beginning after the date of enactment for an unlimited period. However, any losses incurred during those future taxable years will be required to be utilized prior to the losses incurred in pre-enactment taxable years, which carry an expiration date. As a result of this ordering rule, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital loss carryforwards will retain their character as either short-term or long-term capital losses rather than being considered all short-term as permitted under previous regulation. As of December 31, 2011, the Fund does not have any capital loss carryforwards.

Basis of Presentation

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (GAAP) requires management to make estimates and assumptions that affect the reported amount of net assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported results of operations during the reporting period. Actual results could differ from those estimates.

issued. This evaluation did not result in any subsequent events that necessitated recognition or disclosures.

Note 2 – Related-Party Transactions

Investment Management and Fund Administration Fees

Mairs and Power, Inc. (the Adviser) provides investment management and fund administration services to the Fund under written agreements approved by the Board. The Fund is charged an investment management fee paid to the Adviser computed at an annual rate of 0.60% of daily net assets up to $2.5 billion and 0.50% of daily net assets in excess of $2.5 billion. The fund administration fee paid to the Adviser is computed at an annual rate of 0.00375% of daily net assets. For the year ended December 31, 2011, the Fund incurred $75,852 in administration fees from the Adviser, and as of December 31, 2011, had an accrued liability of $6,241 for administration fees payable to the Adviser. Effective January 1, 2012, the fund administration fee paid to the Adviser will be computed at an annual rate of 0.00281% of daily net assets.

Pursuant to a sub-administration agreement between the Fund and U.S. Bancorp Fund Services, LLC (USBFS), the Fund is charged a sub-administration fee paid to USBFS. For the year ended December 31, 2011, the Fund incurred $199,393 in sub-administration fees from USBFS, and as of December 31, 2011, had an accrued liability of $29,619 for sub-administration fees payable to USBFS.

Contributions from Adviser

During the year ended December 31, 2010, the Fund received two contributions from the Adviser related to prospect services and other expenses paid by the Fund from 1980 to 2009, which were in violation of the Investment Company Act of 1940.

NOTES TO FINANCIAL STATEMENTS (continued) December 31, 2011

Note 3 – Indemnifications

In the normal course of business, the Fund enters into contracts that contain general indemnifications to other parties. The Fund's maximum exposure under these contracts is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, based on experience, the Fund expects the risk of loss to be remote.

Note 4 – Distributions Paid, Distributable Earnings and Investment Transactions

Net investment income and net realized gains (losses) may differ for financial reporting and tax purposes because of temporary or permanent book/tax differences. To the extent these differences are permanent, reclassifications are made to the appropriate equity accounts in the period that the difference arises.

Additionally, GAAP requires that certain components of net assets relating to permanent differences be reclassified between financial and tax reporting. These reclassifications have no effect on net assets or net asset value per share. On the Statement of Assets and Liabilities, the following reclassifications were made for the year ended December 31, 2011:

Undistributed Net Investment Income				Undistributed Net Realized Gain (Loss)
	($166,984	)		$	166,984

Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from U.S. generally accepted accounting principles. In addition, due to the timing of dividend distributions, the fiscal year in which the amounts are distributed may differ from the year that the income or realized gains (losses) were recorded by the Fund.

The tax character of distributions paid during the years ended December 31, 2011 and December 31, 2010, were as follows:

	2011		2010
Distributions paid from:
Ordinary income	$	27,997,862	$	25,157,413
Long-term capital gains		25,518,401		26,917,941
	$	53,516,263	$	52,075,354

The Fund designated as long-term capital gain dividend, pursuant to Internal Revenue Code Section 852(b)(3), the amount necessary to reduce the earnings and profits of the Fund related to net capital gain to zero for the tax year ended December 31, 2011.

NOTES TO FINANCIAL STATEMENTS (continued) December 31, 2011

Note 4 – Distributions Paid, Distributable Earnings and Investment Transactions (continued)

At December 31, 2011, the components of accumulated earnings (losses) on a tax basis was as follows:

Cost of investments	$	1,356,190,122
Gross unrealized appreciation	$	766,509,980
Gross unrealized depreciation		(148,139,890	)
Net unrealized appreciation	$	618,370,090
Undistributed ordinary income	$	376,379
Undistributed long-term capital gains		188,763
Total distributable earnings	$	565,142
Total accumulated earnings	$	618,935,232

The difference between book basis and tax basis unrealized appreciation is attributable primarily to the tax deferral of losses on wash sales.

Purchases and sales of investment securities, excluding government securities, short-term securities and temporary cash investments, during the year ended December 31, 2011, aggregated $55,675,201 and $93,130,892, respectively. No purchases and sales of government securities occurred during the period.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors
Mairs and Power Growth Fund, Inc.

We have audited the accompanying statement of assets and liabilities of the Mairs and Power Growth Fund, Inc. (the Fund), including the schedule of investments, as of December 31, 2011, and the related statement of operations for the year then ended, the statements of changes in 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. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits 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 and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2011, by correspondence with the custodian and brokers. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of the Mairs and Power Growth Fund, Inc. at December 31, 2011, the results of its operations for the year then ended, the changes in its 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 U.S. generally accepted accounting principles.

FUND EXPENSES (unaudited)

As a shareholder of the Fund, you incur ongoing expenses for the operation of the Fund (e.g., asset-based charges, such as investment management fees). The Fund is a "no-load" mutual fund. As a result, shareholders pay no commissions, fees, or expenses associated with sales representatives or sales charges.

This example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds. The table below reports the Fund's expenses during the period July 1, 2011 through December 31, 2011 and includes the costs associated with a $1,000 investment.

Actual Expenses

The first line in the table below may be used to estimate the actual expenses you paid over the reporting period. You can do this by dividing your account value by $1,000 and multiplying the result by the expense shown in the table below. For example, if your account value is $8,600, divided by $1,000 = $8.60. Multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period." By doing this you can estimate the expenses you paid on your account during this period.

Hypothetical Example

The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expenses and an assumed return of 5% per year before expenses, which is not the Fund's actual return. The results may be used to provide you with a basis for comparing the ongoing costs of investing in the Fund with the costs of investing in 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 this hypothetical example may not be used to estimate the actual ending account balance or expenses you paid during the period.

	Beginning Account Value 07/01/2011		Ending Account Value 12/31/2011		Expenses Paid During Period *
Actual return	$	1,000.00	$	952.40	$	3.59
Hypothetical assumed 5% return	$	1,000.00	$	1,021.53	$	3.72

* The Fund's expenses are equal to the Fund's annualized expense ratio for the most recent six-month period of 0.73%, multiplied by the average account value over the Fund's second fiscal half-year, multiplied by the number of days in the Fund's second fiscal half-year (184 days), divided by 365 days.

No such tax related non-audit services were performed in the fiscal year ending December 31, 2011.
