An investment bank or an investment banking division is essentially a corporate adviser, acting as an interface between companies and investment markets. The aim is to be the client’s most valued adviser and, as a result of that, deliver and execute deals for them (eg mergers, acquisitions, financing or IPOs). For example, an investment banking team might advise one bank on the acquisition of another.
They would carry out financial and strategic analysis, advise on how to bid for and pay for the bank, offer judgement on the price and advise on how to communicate all of this to the public markets. Investment bankers must be good communicators who are very client-focused and able to offer valuable expertise. Investment banking can also be known as corporate finance.
