The 3Q Team

Fully integrated M&A Consulting in Germany with legal, tax, audit, corporate finance - that's what 3Q's Consulting Services stand for

3Q|Law sees itself as part of a holistic approach to solving your problems and tasks by particularly experienced consultants who have usually gained years of experience in large international law firms, auditing and tax consulting firms, which they were then able to deepen over many more years with consulting projects and experience in medium-sized businesses. In addition, we work with the 3Q approach in a team of tax advisors, auditors, M&A advisors and corporate finance experts who, depending on the task at hand, work across disciplines and establish the necessary cross-links between the individual disciplines. Thus, as 3Q, we deliver fully integrated, holistic solutions instead of isolated solutions.

Legal Note: The team of 3Q, which is put together for the individual project and for your specific needs, is not a law firm or partnership in the legal sense, but a cooperation of independent legal entities, which are usually commissioned individually by you. This has, among other things, the great advantage that you really only have those consultants "on board" that you need for the specific task and who are best qualified "at partner level" for this task.

National and international co-operation with German M&A experts

Furthermore, 3Q Law co-operates with various national and international law and tax consulting firms, so that your interests are also optimally represented in this area.

Special consulting quality in Germany through consulting at owner and partner level

Unlike in many cases in large consulting firms, our individual project team is consistently composed of experienced practitioners at partner level. In the following, we introduce you to some of our permanent cooperation and contact partners:

German Legal advice, German M&A and succession consulting for owner-managed medium-sized businesses.

German M&A and Corporate Finance Consulting for owner-managed medium-sized businesses in Germany

Together with 3Q Law and our other transaction experts from the areas of tax and auditing, CFN Corporate Finance Nord is the ideal partner for primarily the sale but also the purchase of medium-sized companies seeking a succession solution.

M&A Consulting Germany

Whether it is a change of shareholders, a succession plan, a strategic alliance, a spin-off or a corporate crisis - such a transaction is a highly complex process in any situation, which requires not only legal and tax advice, even for smaller transactions, but also, and in particular, the advice of a corporate finance or M&A expert.

Corporate Finance Nord advises you, for example, in close coordination with legal and tax advisors, comprehensively throughout the entire sale or purchase process, e.g. with regard to 

  • Preparation of a company sale, 
  • Business Valuation,
  • Preparation of an information memorandum or sales exposé,
  • Organization of a bidding process and
  • leading the negotiation of the economic conditions
  • Transaction support and management until notarization

Transaction financing Germany

The successful completion of a transaction also requires that the necessary equity and debt capital are available to the buyer when the sale is notarized. However, the financing of such an M&A transaction typically proceeds differently than other financings, as key parameters can still change in the course of due diligence and negotiations.

When is the right time for the buyer to specifically involve its financing partners in the transaction? What is the right financing structure for the buyer? Are there public funding opportunities, who are the right financing partners? With the project experience of Corporate Finance Nord, a professional and experienced partner from 3Q is available to advise you as an acquirer on these important questions and ensure that you receive the appropriate financing.

It is also of considerable importance for the seller, already at an early stage of the sales process, that the financing efforts of the buyer lead to success with the highest possible degree of certainty. With Corporate Finance Nord's extensive practical knowledge of financing issues arising from and in connection with an M&A transaction, we can estimate the financing probability in dialogue with the acquirer and offer you, as the seller, maximum transaction security at this point as well.
