Mergers and acquisitions

Deloitte helps companies and investment funds in the different phases of acquiring a company or selling a business division. Its services are customized to meet the specific needs of each company, with an emphasis on an industry or sector to help define strategies, achieve objectives and identify opportunities.

Deloitte also helps with due diligence services, involving analysis of the target company’s operations and informing the buyer about possible threats and opportunities related to the structure of the transaction and its future operations.

Bringing organizations together through mergers and acquisitions, or carving them out through separations and divestitures, are among the most complex business activities an organization will undertake. The transformational results from a successful transaction can be game-changing—while the risks associated with underperformance or failure are sure to keep executives up at night.

When the stakes are this high, there’s no reason to leave anything to chance. With more than 6,000 M&A professionals in over 150 countries, Deloitte is uniquely placed to advise strategic corporate buyers and private equity investors throughout the entire M&A deal lifecycle. Our range of services and solutions address your integration, consolidation and separation needs throughout the lifecycle of the transaction.

Enhance your competitive advantage before, during, and after the transaction with the power of Deloitte’s proprietary M&A analytics platform iDeal. Its rich data provides deeper intelligence for better-informed decision-making during the due-diligence, negotiation, and post-deal phases.

Whether your organization is focused on tactical growth, business rationalization, or cost reduction, our strategies and solutions are designed to generate maximum value for the business and its shareholders.

Leveraging our professionals’ industry-leading knowledge and powerful, data-driven insights, Deloitte’s M&A Strategy & Diligence service will guide you through the key business and risk-management processes, before, during and after a transaction.

Our Strategic Cost Transformation service helps organizations identify and realize sustainable cost efficiencies across the enterprise in times of restructuring and reorganization. Deloitte’s deep sector experience, enhanced by impactful data analysis, enables clients to derive optimal value from the transaction.

Our professionals will also strategize, design, and implement end-to-end solutions for successful transactions, from advance-planning to post-transaction restructuring. They’ll help you drive performance and results in every key M&A-related function: project management, commercial activity optimization, operations and supply chain, IT systems, human capital management, and finance activities.

Past as prologue

What past M&A trends can tell us about the future.

Acquisition of companies or businesses can be the ideal strategy to accelerate growth of an organization and add value to shareholder equity. However, choosing the acquisition target improperly or not having the qualifications necessary to conduct the process can turn a large opportunity into a problem.

Deloitte assistance in acquisition processes includes multidisciplinary and integrated services that address all phases of the transaction life cycle, with support of local and international specialists in the various stages of the process, allowing identification and anticipation of issues critical to transaction success.


Deloitte consultants help define a merger and acquisition (M&A) strategy that evaluates the constantly changing scenario of the client’s industry, customers and competition to identify growth opportunities and targets aligned with the company’s strategy.


From an appropriate evaluation of the target company to financial, accounting, tax, labor, commercial and operational due diligence, through assistance with tax planning and financing option structuring, Deloitte’s consultants have experience and knowledge to help ensure a successful operation.


Integration of a recently-acquired business represents a number of challenges with costs, deadlines and risks of operating breakdowns. Deloitte has specialists for your "first day," who plan all stages of integration in detail and guide your company through implementation. It is always important to remember that completing an acquisition is not only the end of a successful transaction, but the start of the new phase of a larger and more complex company.
