What is consulting in M&A?

Consulting in M&A is a professional service that helps companies navigate the M&A process and maximize its benefits.

M&A Consultants offer expertise and experience in various areas such as market analysis, target identification, due diligence, negotiation, and integration planning. They work with companies to understand their goals and help them achieve their objectives through the M&A process.

Consulting in M&A also helps companies identify potential risks and opportunities associated with the transaction and provides recommendations to mitigate those risks. They bring a fresh perspective and provide objective insights that help companies make informed decisions.

M&A consulting firms are a critical part of the M&A process as they provide companies with the resources and expertise necessary to succeed in a highly competitive environment. Companies that engage in M&A can benefit greatly from the expertise of consultants and increase the chances of a successful transaction.

What makes a top M&A consulting firm?

A top M&A consulting firm can help companies navigate this process and achieve their goals. But what makes a consulting firm truly "top" in the M&A space?

Investment banks

1.Goldman Sachs: A Wall Street powerhouse

Goldman Sachs, once considered an outsider among the elite investment banks of Wall Street, has risen to the top through decades of success in the 20th century. One of the defining moments in the firm's history was its role as the underwriter for the Ford Motor Company's Initial Public Offering (IPO), propelling it to the forefront of the financial industry.

Despite the challenges posed by the global pandemic in 2020, Goldman Sachs continued to demonstrate its strength as a leading investment bank. The firm advised on several deals in the technology, media, and telecommunications (TMT) sector, including the $5.3 billion acquisition of Plaid by Visa in January.

Despite a decrease in overall deal value, with $966 billion in deals closed in 2020, an 18% decrease from the previous year, Goldman Sachs remains a force to be reckoned with in the world of finance.

2. Morgan Stanley: A leader in strategic acquisitions and advisory services

Morgan Stanley entered 2020 with a continued commitment to strengthening its service portfolio through strategic in-house acquisitions. One of the most notable was the acquisition of E*Trade in February for over $13 billion. This deal provided the bank with access to five million retail investors and invaluable insights into the billions of individual trades made annually.

In addition to its successful acquisitions, Morgan Stanley also shone in its advisory role, playing a significant role in India's Reliance Industries (RIL) $5.7 billion partial buyout by Facebook during the first half of the year. These achievements are a testament to Morgan Stanley's unwavering commitment to providing exceptional services to its clients and staying at the forefront of the financial industry.

3. JP Morgan: A financial powerhouse led by CEO Jamie Dimon

With its dynamic CEO, Jamie Dimon, at the helm, JP Morgan continues to make headlines in the financial industry. In 2020, the company closed a total of 289 transactions, with a combined deal value of $772 billion.

JP Morgan's ambitions are evident as it strives to become the leading name in M&A advisory. The company recently made moves to reinforce its position by attracting some of the most well-known deal-makers in the industry.

It already leads in M&A for insurance underwriters, as demonstrated by its role as the intermediary in AXA's $15.4 billion acquisition of XL Limited in 2020. As one of the most influential players in finance, JP Morgan is a company to watch in the coming years.

4. Citi: A leading advisor in the EMEA region

Citi held an impressive 4th place on the list of leading investment banks in 2019; however, in 2020 it fell back to 6th place. The total volume of deals in which the bank was involved decreased dramatically, dropping 43% from $704 billion in 2019 to $395 billion in 2020. Despite this setback, Citi remains the number one advisor in Europe, the Middle East, and Africa (EMEA) region due to its extensive local presence.

One of the reasons for the decline in transaction volume has been the absence of "megadeals" from Citi's portfolio. Although the bank advised on four deals worth over $1 billion in 2020, there were none with a value in excess of $10 billion. Despite these challenges, Citi remains a formidable player in the world of finance and continues to offer exceptional services to its clients.

5. Bank of America: A financial institution on the rise

Bank of America is experiencing a resurgence in the financial world. Despite a 16% decrease in deal volume compared to 2019, the bank has moved up the M&A rankings for the second year in a row, rising from 5th to 4th place with $551 billion in total deal value.

One of the reasons for this upward trajectory is the bank's growing influence in the oil and gas industry. Bank of America advised on several high-value deals in 2020, including its role as advisor on IFM Investors' $11.2 billion acquisition of Buckeye Partners LP. This position as a leading player in the industry could be a major advantage for Bank of America in the years to come, as the energy sector continues to transition.

Overall, Bank of America's upward momentum is a promising sign for the future of the financial institution, and investors should keep an eye on its continued growth and success.
