Research period review: 31st edition (2020/2021) 

In the research period, the banking and finance team represented lenders in real estate, corporate and sustainability financing. It also represented distressed companies in refinancings and financial restructurings. In financial services regulatory, the team advised clients in the banking and financial services industry on regulatory matters related to FINMA, investment fund structuring, FinIA, FinSA and cryptocurrency.

The capital markets practice mainly worked on debt, equity and structured finance and securitizations transactions, acting for issuers. Debt transactions include covered, high yield, green and investment grade bond issuances. Equity transactions include rights offerings, IPOs, buybacks, public offerings, at the market offerings, capital increases and tender offerings.

In M&A, the team represented both buy and sell side in strategic and private equity acquisitions. Though the team is able to complete transactions across a wide variety of industries, banking, healthcare and technology were big industries during the research period.

The restructuring and insolvency team acted for mostly creditors, but also debtors in out of court restructurings and bankruptcy and insolvency filings.

In terms of lateral moves, partner Katja Schott joined the M&A practice from Wenger Plattner.
