m&a financial

"M&A advisory, and proprietary deal origination capabilities"

M&A, short for mergers and acquisitions, involves one company combining with or purchasing another company to grow, streamline operations, or gain competitive advantages. For investors, M&A activity can signal potential for increased value, new opportunities, or changes in market dynamics, making it an important factor to watch in the business landscape.

View in glossary

growth equity financial

"including growth equity, crossover rounds, and buyouts"

Growth equity is a type of investment where outside investors provide capital to established, revenue-generating companies to accelerate expansion—think of giving a proven small business funds to open many new locations. Investors usually take a minority stake and aim to profit as the company grows in value without changing its core control. For investors, growth equity balances higher return potential than safe bonds with lower risk than early-stage startups, affecting valuation, ownership dilution and future exit prospects.

crossover rounds financial

"including growth equity, crossover rounds, and buyouts"

A crossover round is a late-stage private financing in which investors who normally buy public company shares—such as mutual funds, hedge funds, or other institutional asset managers—participate alongside traditional venture or private equity backers. These rounds typically occur in the months before an initial public offering and can be structured as equity or convertible securities; they let public-market investors build a position in a private company ahead of the IPO and often serve to validate the company’s readiness for public markets. The term principally applies to private, pre-IPO financings and not to routine follow-on financings of already public companies.

private placements financial

"institutional private placements, merger and acquisition"

Private placements are sales of a company’s securities—such as shares or bonds—directly to a small group of selected investors rather than to the general public. Think of it like a private sale to a few buyers who negotiate terms, and it matters to investors because it changes a company’s cash position, can dilute existing ownership, alter control or voting power, and may affect share liquidity and market value when those securities eventually reach public markets.
