The two broad functions
Investment banks help clients raise capital and advise on major corporate transactions. Capital-raising work includes equity and debt offerings, private placements, and other financing. Advisory work includes acquisitions, sales, divestitures, restructurings, defenses, and strategic reviews.
A universal bank may also contain commercial banking, markets, research, asset management, wealth management, transaction banking, and other businesses. Those divisions can collaborate with investment banking but have different clients, products, revenue, and regulations.
Coverage and product groups
Industry coverage groups organize around sectors such as technology, healthcare, industrials, consumer, energy, financial institutions, real estate, or media. They maintain client relationships and understand sector economics.
Product groups specialize in transaction types or financing: mergers and acquisitions, equity capital markets, debt capital markets, leveraged finance, restructuring, or sponsor coverage. Some banks combine responsibilities differently, and regional offices may not contain every group.
The transaction lifecycle
A client question can begin as: Should we buy a competitor? Sell a division? Raise debt? Issue equity? Refinance? Separate a business? The bank analyzes alternatives, prepares valuation and financing work, creates client materials, coordinates internal approvals, and, if mandated, executes the process with lawyers, accountants, investors, lenders, regulators, and counterparties.
How banks earn fees
Advisory fees can include retainers, milestone payments, and success fees. Underwriting economics can include discounts or spreads. Financing and markets businesses can earn interest, trading, or arrangement revenue under their own structures. The economics and conflicts should be understood at a high level without assuming every engagement is paid identically.
What junior bankers produce
Analysts and associates build and update:
- company and industry profiles;
- valuation and financial models;
- pitch books and board materials;
- buyer, seller, lender, or investor lists;
- transaction timelines and process trackers;
- diligence and data-room materials;
- public and private information analyses;
- internal approval materials;
- offering and transaction documents with advisers.
The work combines finance, research, writing, coordination, checking, and version control.
Group differences
M&A can be highly transaction-mechanics and valuation intensive. Capital-markets groups focus on investor demand, issuance, pricing, and market conditions. Leveraged finance focuses on debt capacity and execution. Restructuring focuses on liquidity, claims, legal process, and stakeholder negotiation. Coverage teams develop sector knowledge and can work across products.
A candidate should understand the actual office and group rather than rely on a permanent org chart, because banks reorganize and responsibilities overlap.
