Mairs & Power is announcing two updates to the Mairs & Power Growth Fund that reflect recent regulatory requirements and the firm’s long‑term succession planning. These include a return to the Fund’s original name, the Mairs & Power Fund, and upcoming portfolio management changes. 
 

Fund Name Update

1958 Prospectus

The Mairs & Power Growth Fund will return to its original name, the Mairs & Power Fund, effective April 30, 2026.

 This name change enables the Fund to align with recent amendments to the U.S. Securities and Exchange Commission’s (SEC) “Names Rule,” which requires funds whose names suggest a particular investment focus, such as “growth”, to invest at least 80 percent of their assets in investments consistent with that focus under normal market conditions. This update reflects regulatory requirements only.
 
The Fund’s investment objective, philosophy, and disciplined investment process remain unchanged. Shareholders do not need to take any action as a result of the name change, which is not an exchange or taxable event. The Fund will continue to trade under the same ticker (MPGFX) and CUSIP (89834G711).
 

While the Fund has long focused on investing in high‑quality, growing companies, its disciplined, company‑first approach has never been limited to a single investment style.

 “Our holdings are united not by any one style, but by a straightforward investment strategy focused on durable competitive advantages, the ability to grow faster than the broader market, management teams with a demonstrated record of thoughtful capital allocation and execution, and reasonable valuation levels,” said Andrew (Andy) R. Adams, Chief Investment Officer (CIO) of Mairs & Power. “Removing ‘Growth’ from the Fund’s name allows us to continue investing as we always have.”
 The Fund will continue its multi‑cap approach, focused on growth at a reasonable price, while balancing risk and return through disciplined valuation.
 

Portfolio Management Update

As part of Mairs & Power’s long‑term succession planning, portfolio management updates for the Mairs & Power Fund (formerly the Growth Fund) will take effect June 30, 2026.
    • Pete Johnson will become Lead Manager
    • Andy Adams will transition to Co‑Manager and continue as CIO
    • Chris Strom will join the Fund as Co‑Manager, while continuing as Co‑Manager of the Mairs & Power Small Cap Fund

He has worked alongside previous Mairs & Power Fund lead managers, Bill Frels, Mark Henneman, and Adams. From the beginning of his time at Mairs & Power, Johnson has served as a member of the firm's investment committee, progressively advancing to more senior roles on the investment team and researching companies to provide buy, hold, and sell recommendations.

 

Christopher Strom 270x300Christopher (Chris) D. Strom joined the firm in 2017 and brings deep research experience, including identifying investments that have grown from small‑cap holdings into the Fund’s multi‑cap portfolio. Adding Chris to the Mairs & Power Fund team will further enhance research capacity and his continued role with the Small Cap Fund helps support continuity across strategies. 

 

 

Andy Adams 270x300Andrew (Andy) R. Adams  has served as a manager on the Mairs & Power Fund since 2015 and a lead manager since 2019, while also serving as CIO since 2018. Transitioning to Co-Manager allows Andy to remain actively involved in the Fund, support Pete and Chris in their new roles, and dedicate additional focus to firmwide investment leadership, including the thoughtful evaluation of new technologies that support the investment process. 

 

 

As Minnesota’s oldest investment firm under continuous private ownership and management, Mairs & Power employs a deliberate and disciplined succession planning process designed to ensure continuity in its investment philosophy while supporting the long-term development of its investment professionals. 

A Long-Standing Approach

2026 ProspectusThe Mairs & Power Fund name carries historical significance. The Fund was launched November 11, 1958, to be accessible to investors that did not meet the firm’s individually managed account minimum but wanted the Mairs & Power investing strategy. It was among the first 100 such funds in the United States. In 1962, the name changed to the Mairs & Power Growth Fund. Returning to the original name reflects both the Fund's heritage and its long-standing investment philosophy.

Over 68 years of the Fund’s existence and through six lead managers, the Fund has maintained its long term, bottom-up (company-first) investment approach focused on identifying companies with above-average growth potential, durable competitive advantages, and attractive returns on invested capital, purchased at reasonable valuations. In 2012, Morningstar recognized Fund managers, Bill Frels and Mark Henneman (current Chair Emeritus), as Morningstar’s Domestic Stock Manager of the Year.

Today, the Fund is led by Adams and Johnson, with Strom to join in June. They are supported by an Investment Committee of 17 other investment professionals whose collective knowledge and research inform the Fund’s investments. The Fund follows a multi-cap approach, investing in a concentrated portfolio of 46 stocks in small-cap, mid-cap, and large-cap companies.

As of March 31, 2026, assets under management for the Fund are $5.0 billion.
