News & information

Hamburg, 17 November 2025. The Hamburg-based corporate group Münchmeyer Petersen & Co. (MPC), whose roots date back to 1846, is launching the capital markets boutique Münchmeyer Petersen Capital Markets (MPCM). The new Hamburg-based entity positions itself as a partner to medium-sized entrepreneurs and companies in all capital-market-related matters while also offering investors access to investment opportunities in small and mid-sized companies (SMID caps).

Expertise for the Mittelstand

A key element of the new unit’s initial setup is the acquisition of Warburg Research GmbH—one of the leading research houses for German small- and mid-cap companies. This unit will form the nucleus of MPCM’s research capabilities and will be strategically aligned with the positioning of the new company following the planned closing at the end of November.

MPCM positions itself as a modern capital markets boutique: in addition to in-depth analysis, it offers tailored solutions for equity and debt financing (Equity and Debt Capital Markets, ECM/DCM) for medium-sized companies, as well as direct access to investors and markets. MPCM is led by Ebrahim Attarzadeh, who brings extensive leadership experience in investment banking—among other roles, as CEO of MainFirst Bank AG and later CEO of Stifel Europe Bank AG—in addition to his own entrepreneurial background. Co-Managing Director will be Felix Pröfrock, currently Head of Capital Markets at M.M.Warburg & CO (“MMW”), who will be particularly responsible for the primary market business in equities and bonds. In addition to its headquarters in Hamburg, MPCM will initially have a branch office in Frankfurt and plans to open additional offices over time.

Driving force for the capital market

“Entrepreneurial drive has been the hallmark of MPC for nearly 200 years. From our own experience, we know how important the capital market can be for medium-sized companies and what opportunities it can offer both for the company and for investors. With MPCM, we are reviving the concept of a traditional merchant bank and combining it with our own DNA: entrepreneurial, independent, technology-driven—and grounded in the values that have guided our group for generations,” says Dr. Axel Schroeder, Managing Partner of MPC.

“We are pleased that the extensive expertise of our subsidiary Warburg Research GmbH in the small- and mid-cap segment will now find a new home at Münchmeyer Petersen Capital Markets. In addition, the sale to the MPC Group creates a ‘Hamburg solution’ that strengthens the Hamburg financial center,” says Stephan Schrameier, Board Member of M.M.Warburg & CO. The private bank is sharpening its strategic focus on private banking and financing and is therefore withdrawing from the institutional capital markets business. “We thank both the colleagues at Warburg Research and Mr. Pröfrock for their commitment to M.M.Warburg & CO and wish them all the best for the future,” Schrameier adds.

In the course of 2026, the new owner intends to rename the company, which will then no longer carry the “Warburg” name.
