MAIRS & POWER FUNDS MARKET COMMENTARY (unaudited)

June 30, 2014

While the pace of the economic recovery was somewhat better than expected during the quarter, we continued to keep our primary focus on the long-term fundamental attributes that make companies profitable. While attentive, we are not swayed by the macro-economic details underpinning global market events. By emphasizing the long-term view, we can make the subtle, opportunistic adjustments to company positions over time that keep portfolio turnover low and tax consequences in check. Our first mutual fund, the Mairs & Power Growth Fund, founded in 1958, provides a good illustration of this approach, which is employed by the Mairs & Power Balanced and Mairs & Power Small Cap Funds as well. Portfolio turnover for the Growth Fund, compared to its peers, the Morningstar U.S. Large Cap Blend category, was substantially lower for each of the past 10 years. As a result, the Fund's annual realized taxable capital gains exceeded $1.00 per share in only two of the past 10 years.

As measured by the S&P 500 Index, the stock market advanced 5.23% for the quarter ending June 30, 2014. The market's strength occurred against a mixed backdrop characterized by a downbeat adjustment to the Gross Domestic Product (GDP) (a key barometer of economic health), a rekindling of the war in Iraq, and hints that higher inflation and rising yields might be just around the corner.

The quarter's biggest economic news was the unexpectedly sharp downward revision of the first quarter's GDP growth rate from -1% to -2.9%. Like a house guest who won't leave, the effects of winter's record cold snap endured and played a major role in depressing the benchmark growth measure, which opened up questions about the long-term hardiness of the U.S. recovery.

Meanwhile, as the Iraq war began appearing on the front pages again, the markets experienced some déjà vu: Would this be like 2003 all over again, when America first conquered Baghdad? The answer turned out to be a "no." Shrugging off short-term inflationary fears from rising energy prices, the markets behaved with much more equanimity than they did 11 years ago when America's energy independence goals were still far in the future. Instead, our energy selections were able to benefit from new access to cheaper domestic oil reserves as well as growing demand for improved technologies related to fracking.

Concerns about rising yields and the inflation rate were short-lived as well. Analysts found their expectations subverted when the benchmark 10-year Treasury rate declined from a high of more than 2.80% earlier in the quarter to 2.53% by the end of the period, and the Barclays Government/Credit Bond Index gained 1.92%. Elsewhere, the Federal Reserve (Fed) continued to dial back its monthly bond purchases by an additional $10 billion more per month. In short, the combined threats of the seemingly everlasting Polar Vortex, the Iraq war and inflationary fears could not dampen investor enthusiasm for stocks during the second quarter.

Future Outlook

Everybody likes a winner. And, if the stock market was any gauge during the second quarter, there was a lot to like. Stocks extended their winning streak for the sixth consecutive quarter, as measured by the Standard & Poor's 500 Index – a phenomenon surpassed only six other times since 1928. After such historic gains, though, should cautious investors grow concerned about the second half of the year? We don't think so. Successful investment approaches never depend on the positive or negative market performance of any single quarter. At Mairs & Power, we base our portfolio decisions on the facts about companies, not the markets. In particular, we endeavor to identify and invest in those companies that have shown their ability to achieve consistent, above-average growth from a position of demonstrable and durable competitive advantage.

Looking toward year-end, we will continue to closely evaluate corporate earnings and revenue against the multiples we view to be still slightly above historical levels. The price/earnings (P/E) multiple of the S&P 500 Index, a key gauge of corporate earnings health, stood just above its long term average of around 15.5 at quarter-end, almost exactly where it ended the first quarter. This is further proof to us that stock prices

MAIRS & POWER FUNDS MARKET COMMENTARY (unaudited) (continued)

continue to be influenced more by actual, organic company earnings and revenue growth than by the Federal Reserve's waning stimulus program.

While we believe economic conditions appear sufficiently strong to support this current, positive earnings trend, a market correction in the near term would not surprise us. The advantages of investing in well-diversified portfolios, rebalanced regularly, provide one of the better, more reliable routes for meeting long-term goals regardless of the quarter. By focusing our attention on companies and how they perform, we remain confident in our ability to identify, over the course of a full market cycle, those proﬁtable, well-managed ﬁrms likely to outperform their competitors regardless of marketplace events.

To Our Shareholders: June 30, 2014

For the second quarter and six months ending June 30, 2014, the Mairs & Power Growth Fund gained 2.87% and 4.18% respectively, underperforming its benchmark, the S&P 500 Index, which gained 5.23% and 7.14%, and the Lipper Multi Cap Core, its peer group, at 4.52% and 6.25%, for the periods.

The world's leading supplier of energy industry technology solutions, Schlumberger, was a top contributor to performance for both the past quarter and the past six months through June 30, gaining 20.97% and 30.90%, respectively. America's move to greater energy independence that began more than a decade ago has continued to benefit firms like Schlumberger whose businesses are concentrated in the area of oil and gas exploration. Many factors, however, like global economics and shifting political allegiances can affect both energy prices and exploration budgets. Since 2008, Schlumberger has endeavored to temper the impact of such cyclical influences through major investments in technology innovations, product reliability and better processes. As it gains market share, Schlumberger continues to hold leading market positions in proprietary software, patents, and major equipment.

Freight shipper and global supply chain consultant C.H. Robinson Worldwide, Inc. gained 21.76% and 9.34% respectively for the second quarter and first six months, and was a strong contributor to Fund performance. The firm's efforts to better service high-end customers resulted in a favorable report in the first quarter and helped reverse a lackluster, two-year performance trend. As the requirement for "just-in-time" freight delivery becomes increasingly important to a company's profitability, customers will turn to third-party logistics firms like C.H. Robinson to coordinate shipments and generate the information customers need in real time to manage their inventories and deliveries.

Healthcare company Medtronic, Inc. also contributed to performance, gaining 3.61% and 11.10% for the second quarter and first six months, respectively. Pending a shareholder vote later this year or in 2015, however, Medtronic is expected to merge with medical device supplier Covidien Plc and change its legal domicile to Ireland. Once completed, the merger will create a taxable event for Fund shareholders who will realize a long-term capital gain estimated at $60 million or $1.50 a share. We also anticipate the Fund may realize another $1.50 per share in non-Medtronic capital gains by year-end. As you know, Mairs & Power is committed to a policy of low portfolio turnover, and reduced tax exposure; and we consider this tax event to be an

anomaly. Through our long-term approach, we make adjustments to company positions over time that keep portfolio turnover low and tax consequences in check. The Fund, founded in 1958, actually provides a good illustration of this approach. Compared to its Morningstar U.S. Large Cap Blend category, portfolio turnover for the Fund was substantially lower for each of the past 10 years, while realized annual taxable capital gains exceeded $1.00 per share in only two of the past 10 years.

The largest detractor from performance during the quarter was Cray Inc., a major super computer manufacturer. However, given our long-term view of the company, we took advantage of this attractive valuation to increase our position. A number of other industrial companies in our portfolio detracted from performance, including Toro Company, a major provider of landscape maintenance equipment. Due, in part, to last winter's unseasonably cold weather, the firm lowered earnings expectations. Prior to the disappointing earnings report, we had scaled back our position somewhat, while retaining the firm as a top 10 holding based on our conviction that Toro's strong product lineup is likely to deliver revenue growth later in the year. We continue to be enthusiastic about the long-term prospects of three other industrial companies, Pentair, Graco and 3M. Portfolio adjustments are part of our overall strategy; to keep portfolio turnover low, while still taking advantage of opportunities when the market presents them to us.

MAIRS & POWER BALANCED FUND (unaudited)

To Our Shareholders: June 30, 2014

For the second quarter and six months ending June 30, 2014, the Mairs & Power Balanced Fund gained 3.82% and 5.92% respectively, in line with its benchmark composite index (60% S&P 500 Index and 40% Barclays Government/Credit Bond Index), which gained 3.90% and 5.90% for the periods.

The pace of the economic recovery continued steadily through the first half of the year. It seems a little surprising that it was only 12 months ago last May when the market went into full flight to safety mode after the Federal Reserve (Fed) announced it would scale back the stimulus policy of quantitative easing (QE) sometime in the fall of 2013. All in all, the market stayed in a cool, calm and collected mood during the first half of the year and took war, stimulus tapering, hints of inflation and rising yields in stride.

In general, our selections in energy and higher dividend stocks benefited the portfolio. America's move to greater energy independence which began more than a decade ago has continued to benefit firms like Schlumberger whose businesses are concentrated in oil and gas exploration. Accordingly, Schlumberger proved to be a top contributor to Fund performance for both the past quarter and the past six months through June 30, and gained 20.97% and 30.90%, respectively. Since 2008, Schlumberger has made major investments in technology innovations, product reliability and better processes. As it gains market share, the firm continues to hold leading market positions in proprietary software, patents, and major equipment.

Another strong contributor to performance in the first half of the year was global supply chain consultant C.H. Robinson Worldwide, Inc., which gained 21.76% and 9.34% respectively for the second quarter and first six months. The firm's efforts to better service high-end customers resulted in a favorable report in the first quarter and helped reverse a downbeat, two-year performance trend. At its attractive levels of value, we continued to add to our position in C.H. Robinson during the first half of the year.

Healthcare company Medtronic, Inc. also contributed to performance, gaining 3.61% and 11.10% for the second quarter and first six months, respectively. Pending a shareholder vote either later this year or in 2015, however, Medtronic is expected to merge with medical device supplier Covidien Plc and change its legal domicile to Ireland. Once completed, the merger will create a taxable event for Fund shareholders who will realize a long-term capital gain estimated at $5.5 million or $0.75 a share. As always, Mairs & Power is committed to a policy of low portfolio turnover, and low exposure to taxable gains; we view this tax event as an anomaly.

Performance detractors included Pentair, IBM and Target. However, we did not trim any of our positions as we continue to view these selections favorably over the long-term.

MAIRS & POWER BALANCED FUND (unaudited) (continued)

On the income side, we saw our companies increase their dividends at a rate that outpaced the dividend for our benchmark through the first half of the year. Additionally, interest rates generally declined, especially bonds with durations of 10 years and beyond on the Treasury curve. Overall, bond prices improved during the first half of the year. Accordingly, we maintained a concentration in investment-grade bonds with longer durations as we saw a tightening in yield spreads in the U.S. Government sector. We still think more may be gained on the fixed income side as the Federal Reserve continues to taper back on quantitative easing. For investors who prefer a single vehicle that can straddle the equity and fixed income markets to take advantage of growth opportunities as well as favorable movements in the debt markets, we believe the Mairs & Power Balanced Fund continues to offer an effective way to do so.

MAIRS & POWER SMALL CAP FUND (unaudited)

To Our Shareholders: June 30, 2014

The Mairs & Power Small Cap Fund turned in a solid performance for the first half of the year returning 5.61% compared to 3.22% for its benchmark, the S&P SmallCap 600 Index. For the same period, the Lipper Small Cap Core Funds Index, its peer group, returned 3.83%. Additionally, for the quarter, the Fund gained 2.30%, outperforming its benchmark at 2.07% and slightly lagging the Lipper peer group at 2.57%.

It's encouraging to see the Fund continue to make up lost ground on the index after last year's modest underperformance, and continue to perform well relative to its peers. By design, sector allocation had little impact on relative performance. In keeping with Mairs & Power's approach, it was individual stock selection that once again drove outperformance in the first half. The portfolio benefited as oil prices moved up sharply and our comparative overweight to that sector contributed to relative performance. Additionally, an underweight in the consumer discretionary sector helped performance, as the sector is actually down so far this year. Conversely, while we believe in the long-term potential in many industrial companies, they detracted slightly from relative performance as that sector overall increased only slightly for the year.

Past performance is no guarantee of future results.

Small cap stocks lagged behind larger cap stocks in the first half of 2014. This underperformance brought small cap valuations down a bit relative to large cap stocks. However, there continues to be more of a premium for small companies than historically has been the case. We believe this is justified based on the underlying revenue and earnings growth prospects for smaller companies.

Gentherm, a manufacturer of automobile seat heating and cooling equipment, contributed the most to outperformance for the six-month and second-quarter periods, through June 30, returning 65.80% and 28.02%, respectively. Gentherm continues to benefit from increased inclusion of its products on Original Equipment Manufacturer (OEM) auto platforms as well as from other applications of its proprietary technology (consider how welcome heated seats would have been during Minnesota's brush with the Polar Vortex last winter). The password authentication hardware and software firm Vasco Data Security also contributed heavily to performance for both the six-month and second-quarter periods, returning 50.06% and 53.85%, respectively. Having an already strong European consumer banking presence, Vasco has now started to make inroads into the U.S. market. Every day, new headlines trumpeting widespread data vulnerabilities help to drive up greater demand for this firm's products.

In contrast, the radiation detection firm Landauer proved to be the biggest laggard in the first half of the year. However, a number of recent regulatory changes that address shortfalls in U.S. hospital radiation monitoring appear likely to provide the company with an opportunity to turn their stock performance around.

Portfolio additions during the second quarter included United Fire Group, a company based in Cedar Rapids, Iowa that writes property and casualty insurance, life insurance, and offers annuities. With a strong history of conservative underwriting, this steady performer grew its Return on Equity (ROE) 10% last year, while its stock traded at a discount to book value – considered a rare event at current valuations. Another aspect we like about this company is that its management goes out of its way to tell potential investors that, while they must report their results quarterly, they manage their company for the much longer term; music to our ears.

All investments have risks. The Small Cap Fund is designed for long-term investors. Equity investments are subject to market fluctuations, and the Fund's share price can fall because of weakness in the broad market, a particular industry, or specific holdings. Investments in small and midcap companies generally are more volatile. International investing risks include among others political, social or economic instability, difficulty in predicting international trade patterns, taxation and foreign trading practices, and greater fluctuations in price than United States corporations. The Fund may invest in initial public offerings by small cap companies, which can involve greater risk than investments in companies that are already publicly traded.

Return on Equity (ROE) is the amount of net income returned as a percentage of shareholders equity. Return on equity measures a corporation's profitability by revealing how much profit a company generates with the money shareholders have invested.

Lipper Small Cap Core Funds Index is an unmanaged index considered representative of small-cap core funds tracked by Lipper. It is not possible to invest directly in an index.

The S&P SmallCap 600 Index is an index of small company stocks managed by Standard & Poor's that covers a broad range of small cap stocks in the United States. The index is weighted according to the market capitalization and covers about 3-4% of the total market for equities in the United States. It is not possible to invest directly in an index.

NOTES TO FINANCIAL STATEMENTS (unaudited) June 30, 2014

Note 1 – Organization and Significant Accounting Policies

The Mairs & Power Funds Trust (the Trust) is a no-load, diversified, open-end management investment company registered under the Investment Company Act of 1940, as amended (the 1940 Act). Mairs & Power Growth Fund (the Growth Fund), Mairs & Power Balanced Fund (the Balanced Fund), and Mairs & Power Small Cap Fund (the Small Cap Fund) (individually a Fund and collectively the Funds) are series within the Trust. The objective of the Growth Fund is to provide shareholders with a diversified portfolio of common stocks, which have the potential for above-average, long-term appreciation. The objectives of the Balanced Fund are to provide shareholders with regular current income, the potential for capital appreciation and a moderate level of risk by investing in a diversified portfolio including bonds, preferred stocks, common stocks, and other securities convertible into common stock. The objective of the Small Cap Fund is to seek above-average, long-term appreciation.

Significant accounting policies of the Funds are as follows:

Security Valuations

Security valuations for the Funds' investments are furnished by independent pricing services that have been approved by the Trust's Board of Trustees (the Board). Investments in listed equity securities are valued at the last quoted sale price on the securities exchange on which such securities are principally traded or 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 valued at the last quoted bid price. Debt obligations exceeding 60 days to maturity are valued by an independent pricing service. The pricing services may employ methodologies that utilize actual market transactions, broker-dealer supplied valuations, or other formula-driven valuation techniques. These techniques generally consider overall market conditions and such factors as yields or prices of bonds of comparable quality, type of issue, coupon, maturity and ratings. Debt obligations with 60 days or less remaining until maturity may be valued at their amortized cost, which approximates market.

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. When market quotations are not readily available, or when 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 June 30, 2014, no securities in the Funds were valued using this method.

Fair Valuation Measurements

The Trust 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 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 Funds' own assumptions in determining the fair value of investments).

NOTES TO FINANCIAL STATEMENTS (unaudited) (continued) June 30, 2014

Note 1 – Organization and Significant Accounting Policies (continued)

The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The following is a summary of the inputs used to value the net assets of each Fund as of June 30, 2014:

	Growth Fund		Balanced Fund		Small Cap Fund
Level 1*	$	4,260,510,495	$	428,673,489	$	140,855,029
Level 2**		-		229,829,708		-
Level 3		-		-		-
Total	$	4,260,510,495	$	658,503,197	$	140,855,029

* All Level 1 investments are equity securities (common stocks and preferred stocks and securities) and short-term investments.

** All Level 2 investments are fixed income securities, excluding preferred securities.

For detail of securities by major sector classification for the Funds, please refer to the Schedules of Investments.

The Funds had no transfers amongst levels during the period and did not hold any Level 3 investments at either June 30, 2014 or December 31, 2013.

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

Income Taxes

Each Fund is a "regulated investment company" as defined in Subtitle A, Chapter 1, Subchapter M of the Internal Revenue Code, as amended (the Code). No provisions have been made for federal income taxes as it is the intention of each 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 June 30, 2014, the Trust 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 or, for the Small Cap Fund, all tax returns filed since commencement of operations.

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.

In preparing these financial statements, the Funds have evaluated events and transactions for potential recognition or disclosure through the date the financial statements were available to be issued. This evaluation did not result in any subsequent events that necessitated recognition or disclosures.

NOTES TO FINANCIAL STATEMENTS (unaudited) (continued) June 30, 2014

Note 2 – Related-Party Transactions

Common expenses incurred by the Trust are allocated among the Funds based on their relative assets. Fund specific expenses are charged directly to the Fund that incurred the expense.

Investment Management and Fund Administration Fees

Mairs and Power, Inc. (the Adviser) provides investment management services to the Funds under a written agreement (the Management Agreement) approved by the Board.

Pursuant to the Management Agreement, the Adviser is paid a monthly fee on average daily net assets at the following annual rates:

	Growth Fund			Balanced Fund			Small Cap Fund*
Up to $2.5 Billion		0.60	%		0.60	%		0.90	%
Over $2.5 Billion		0.50	%		0.60	%		0.90	%

The Adviser provides fund administration services to the Funds under a written fund administration servicing agreement approved by the Board. The fund administration fee paid to the Adviser is computed at an annual rate of 0.00281% of average daily net assets. Fund administration fees incurred for the six months ended June 30, 2014 and fund administration fees payable to the Adviser as of June 30, 2014 were as follows:

	Growth Fund		Balanced Fund		Small Cap Fund
Fund administration fees incurred	$	56,567	$	8,346	$	1,757
Fund administration fees payable		9,748		1,495		314

Pursuant to a sub-administration agreement between the Funds and U.S. Bancorp Fund Services, LLC (USBFS), the Funds are charged a sub-administration fee paid to USBFS. Sub-administration fees from USBFS incurred for the six months ended June 30, 2014 and sub-administration fees payable to USBFS as of June 30, 2014 were as follows:

	Growth Fund		Balanced Fund		Small Cap Fund
Sub-administration fees paid	$	305,818	$	26,610	$	7,220
Sub-administration fees payable		148,992		22,803		3,518

* The Adviser has agreed to waive the Small Cap Fund's investment management and fund administration fees and reimburse expenses to the extent necessary to prevent total annual fund operating expenses (excluding interest, taxes, brokerage commissions, Acquired Fund Fees and Expenses, other investment-related costs and other extraordinary expenses, such as litigation and other expenses not incurred in the ordinary course of the Small Cap Fund's business) from exceeding 1.25% of daily net assets through April 30, 2015. The Adviser cannot terminate this arrangement before that date without the agreement of the Board.

Trustees' Compensation

The Funds pay compensation to the disinterested Trustees of the Trust. The Funds do not pay remuneration to officers or to Trustees who are officers, directors or employees of the Adviser.

Note 3 – Indemnifications

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

NOTES TO FINANCIAL STATEMENTS (unaudited) (continued) June 30, 2014

Note 4 – Distributions Paid, Distributable Earnings and Investment Transactions

Net investment income and net realized capital 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.

Distributions to shareholders are determined in accordance with income tax regulations that may differ from GAAP, and due to the timing of the 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 each Fund.

The tax character of distributions paid during the six months ended June 30, 2014 and the fiscal year ended December 31, 2013, were as follows:

Six months ended June 30, 2014
Distributions paid from:	Growth Fund		Balanced Fund		Small Cap Fund
Ordinary income	$	28,364,825	$	7,041,475	$	-
Long-term capital gains		947,458		-		-
Total distributions paid	$	29,312,283	$	7,041,475	$	-
Year ended December 31, 2013
Distributions paid from:	Growth Fund		Balanced Fund		Small Cap Fund
Ordinary income	$	41,523,920	$	11,171,731	$	287,673
Long-term capital gains		50,378,427		718,476		1,497,354
Total distributions paid	$	91,902,347	$	11,890,207	$	1,785,027

Ordinary income distributions include net short-term capital gains. The Funds designate the long-term capital gains presented above as capital gains dividends under the Internal Revenue Code.

At December 31, 2013, the components of accumulated earnings (losses) on a tax basis were as follows:

	Growth Fund			Balanced Fund			Small Cap Fund
Cost of investments	$	2,084,675,163		$	428,826,291		$	86,222,918
Gross unrealized appreciation	$	1,913,311,633		$	143,023,727		$	26,428,872
Gross unrealized depreciation		(38,648,912	)		(12,587,187	)		(507,308	)
Net unrealized appreciation	$	1,874,662,721		$	130,436,540		$	25,921,564
Undistributed ordinary income	$	-		$	72,872		$	-
Undistributed long-term capital gains		947,485			266			-
Total distributable earnings	$	947,485		$	73,138		$	-
Other accumulated earnings		-			-			(291,791	)
Total accumulated earnings	$	1,875,610,206		$	130,509,678		$	25,629,773

The difference between book basis and tax basis unrealized appreciation is attributable primarily to the tax deferral of losses on wash sales and the tax cost basis adjustment due to receipt of return of capital distributions from certain investments.

FUND EXPENSES (unaudited)

As a shareholder of the Funds, you incur two types of costs: (1) transaction costs including redemption fees and (2) ongoing expenses for the operation of the Funds (e.g., asset-based charges, such as investment management fees). The Funds are "no-load" mutual funds. 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 Funds and to compare these costs with the ongoing costs of investing in other mutual funds. The table below reports the Funds' expenses during the period January 1, 2014 through June 30, 2014 and includes the costs associated with a $1,000 investment.

Actual Expenses

The first line in the tables 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 tables below provides information about hypothetical account values and hypothetical expenses based on the Funds' actual expenses and assumed returns of 5% per year before expenses, which are not the Funds' actual returns. The results may be used to provide you with a basis for comparing the ongoing costs of investing in the Funds with the ongoing costs of investing in other funds. To do so, compare these 5% hypothetical examples with the 5% hypothetical examples that appear in the shareholder reports of other funds.

BOARD OF TRUSTEES' APPROVAL OF INVESTMENT ADVISORY CONTRACT (unaudited)

The Board of Trustees (the Trustees) unanimously approved the Agreement for Investment Counsel Service (the Advisory Contract) between Mairs & Power Funds Trust (the Trust) on behalf of the Mairs & Power Growth Fund (the Growth Fund), the Mairs & Power Balanced Fund (the Balanced Fund) and the Mairs & Power Small Cap Fund (the Small Cap Fund) (each, a Fund and together, the Funds) and Mairs and Power, Inc. (the Adviser) at a meeting of the Board of Trustees held on May 12, 2014. In evaluating the Advisory Contract, the Trustees took into account their cumulative experience with the Adviser and their ongoing review and discussion with the Funds' portfolio managers at meetings throughout the year.

In preparation for the May 12, 2014 meeting, the Adviser provided the Trustees with extensive materials that are relevant to the Trustees' consideration of the Advisory Contract. As part of their discussion at the May 12 meeting, the independent Trustees discussed the materials and the proposed renewal of the Advisory Contract in executive session with legal counsel present, but with no representatives of the Adviser being present. In reaching their decision to renew the Funds' Advisory Contract with the Adviser, the Trustees considered all factors they believed to be relevant. Each of these factors and the conclusions reached by the Trustees with respect to these factors helped form the basis for the decision to renew the Advisory Contract with the Adviser and are discussed below. In their deliberations, the Trustees did not identify any single factor as determinative.

Nature, Extent and Quality of Services

With respect to the quality and extent of the Adviser's services provided to the Funds, the Trustees noted the Funds' solid performance records over the applicable periods, as discussed in more detail below under "Investment Performance." The Trustees considered the Adviser's extensive experience as an investment adviser and the services it would continue to provide the Funds and their shareholders under the Advisory Contract. They noted the Adviser's succession planning for the portfolio managers of the Growth and Balanced Funds, with Mark L. Henneman and Ronald L. Kaliebe being named lead portfolio managers of the Growth Fund and Balanced Fund, respectively, effective

BOARD OF TRUSTEES' APPROVAL OF INVESTMENT ADVISORY CONTRACT (unaudited) (continued)

July 1, 2013 in preparation for the retirement of William B. Frels at the end of 2014. The Trustees considered the Adviser's disciplined investment decision-making process, including its emphasis on Midwest stocks and generally low portfolio turnover. The Trustees also took into account other components of the services provided by the Adviser to the Funds, such as monitoring compliance with applicable requirements under the securities laws, service provider oversight, the Adviser's distribution strategy, the Adviser's risk management system and results of the most recent compliance review. The Trustees concluded that overall they were satisfied with the nature, extent and quality of services provided by the Adviser under the Advisory Contract.

Investment Performance

In reviewing the Funds' performance, the Trustees considered the information provided in connection with the May 12, 2014 Board meeting, noting that they also receive detailed performance information at each regular Board meeting during the year. At the May 12, 2014 meeting, the Trustees considered the investment results for the Funds compared to those mutual funds with similar investment objectives as determined by Morningstar, a representative peer group of funds with similar investment objectives and strategies as determined by the Adviser and to each Fund's respective performance benchmarks. With respect to the Growth Fund and the Balanced Fund, the Trustees reviewed comparative performance information for the one-, five-, ten-year and since-inception periods ending December 31, 2013. The Trustees noted that the investment performance of the Growth Fund and the Balanced Fund was in line with or exceeded the average return of the relevant peer groups and benchmark indices over most of those time periods. With respect to the Small Cap Fund, the Trustees reviewed comparative performance information for the one-year and since-inception periods ended December 31, 2013. The Trustees noted that the Small Cap Fund's performance has exceeded its peer group average during those periods and also exceeded the Morningstar category average for the past one-year period. The Small Cap Fund trailed the benchmark index for the past one-year period but outperformed the benchmark index for the since-inception period. Based upon their review, the Trustees concluded that each Fund's investment performance has been satisfactory.

Management Fees

In evaluating the level of the management fees paid to the Adviser, the Trustees considered both the amount of the fees and the overall expenses of the Funds, compared to those of other similar mutual funds, as well as the quality and quantity of advisory and other services provided by the Adviser. The Trustees noted that the management fees paid to the Adviser by the Growth Fund and the Balanced Fund are either below or in line with the average fees for Morningstar's respective peer group for each Fund and for the peer group of competitive funds identified by the Adviser. Additionally, the Trustees noted that the Balanced Fund's and Growth Fund's total expense ratios are below the average total expense ratios of funds in their Morningstar peer groups and the competitive funds identified by the Adviser. With respect to the Small Cap Fund, the Trustees noted that while the management fee was above the Morningstar and peer group averages, the Fund's total expense ratio was below the Morningstar and peer group averages. The Trustees also considered the Adviser's agreement to waive fees and reimburse the Small Cap Fund's expenses through April 30, 2015 to the extent necessary to limit the annual operating expenses of the Fund for each fiscal year, as a percentage of the Fund's average daily net assets, to 1.25%.

The Trustees then reviewed the fees the Adviser charges its non-mutual fund advisory clients, including retirement funds, other institutional clients and individuals (Advisory Clients) with investment objectives similar to those of the Growth Fund and Balanced Fund, noting that none of the Advisory Clients currently is invested in a small cap investment mandate. The Adviser provided the Trustees with information about the new fee schedule for Advisory Clients opening accounts after April 1, 2014 and the differences in the scope of services provided to its Advisory Clients compared with the scope of those it provides to the Funds. Management noted that the level of investment decision-making is considerably higher with respect to the Funds, because cash flows result in purchase and sale decisions being made by the Adviser virtually every trading day. Other services provided by the Adviser to the Funds include certain administrative services, oversight of the Funds' other service providers, trustee support and

BOARD OF TRUSTEES' APPROVAL OF INVESTMENT ADVISORY CONTRACT (unaudited) (continued)

providing office facilities and Fund officers. Having considered all of these factors, the Trustees concluded that the Funds' management fees are fair and reasonable for the services provided.

Costs of Services Provided and Profitability to the Adviser

At the request of the Trustees, the Adviser provided information regarding the Adviser's overall profitability as well as the allocation of profitability between Advisory Clients and the Funds. The profitability of the mutual fund business was further broken down among the Growth, Balanced and Small Cap Funds, as applicable. The Trustees reviewed the Adviser's financial assumptions and methods of expense allocation used. The Trustees noted that the profitability calculation includes fees received by the Adviser under both the Administrative Servicing Agreement and the Advisory Contract. The Trustees believe that the Adviser should be entitled to earn a reasonable level of profit for the services it provides to the Funds. The Trustees also reviewed the Adviser's financial condition and determined it to be sound. Based on their review, the Trustees concluded that the Adviser's level of profitability from its relationship with the Funds is reasonable.

Other Benefits

The Trustees considered the benefits to the Adviser from soft dollar arrangements whereby the Adviser receives proprietary investment research services from broker-dealers that execute the Funds' purchases and sales of securities. As a general matter, the research services received from broker-dealers are used to service all accounts that invest in equity securities. The Trustees received and reviewed information concerning the Funds' brokerage commissions and allocation of Fund brokerage. The Trustees recognized that the Adviser's profitability would be lower if it did not receive proprietary research for soft dollars in connection with the Funds' brokerage activity. In addition, the Trustees considered that the Adviser's Advisory Clients benefit from access to and research obtained from brokers executing trades on behalf of the Funds. While difficult to measure, the Trustees concluded that the benefits the Adviser receives in this way is fairly modest, given the Funds' relatively low portfolio turnover rates and the research capability that the Adviser itself maintains. The Trustees noted that the Adviser derives reputational benefits from its association with the Funds as well. The Trustees considered the nature and amount of fees paid by the Funds for administrative services provided by the Adviser under the Fund Administration Servicing Agreement. The Trustees concluded that the other benefits realized by the Adviser from its relationship with the Funds were reasonable.

Economies of Scale

The Trustees reviewed the extent to which economies of scale may be realized as the Funds increase in size. The Trustees noted the recent asset growth in each of the Funds. The Trustees noted that the Adviser's approach has been to keep costs to the Funds as low as reasonably possible, including management fee levels. At the same time, the Adviser believes, and the Trustees concur, that it is entitled to earn reasonable returns on its mutual fund business. The Adviser acknowledged that while it is difficult to pinpoint the economies of scale to be realized by the Funds at any particular asset level, there is no question that such economies exist. Accordingly, the Adviser, under the terms of the Advisory Contract for the Growth Fund, established a breakpoint at the $2.5 billion asset level. The breakpoint reduces the management fee applicable to assets managed in excess of $2.5 billion from 60 basis points (0.6 of 1%) to 50 basis points (0.5 of 1%). The Trustees reaffirmed their conclusion that establishing this breakpoint at $2.5 billion forms a reasonable basis for having management fee levels reflect economies of scale for the benefit of Growth Fund shareholders. The Adviser believes, and the Trustees concur, that the consideration of establishing a breakpoint at certain asset levels would be an appropriate way for the Adviser to share its economies of scale in the event that the Balanced and Small Cap Funds were to grow their assets substantially. With respect to the Balanced Fund, considering its current level of assets and low management fee, the Trustees concluded that the absence of breakpoints in the Fund's management fee is reasonable at this time. With respect to the Small Cap Fund, considering its current level of assets and the Adviser's agreement to waive fees and reimburse the Fund's expenses pursuant to the expense waiver agreement mentioned above, the Trustees concluded that the absence of breakpoints in the Fund's management fee is reasonable at this time.
