Global law firm DLA Piper announced the strategic appointment of two partners to its Financial Regulatory and Capital Markets practices. Cathrine Foldberg Møller has joined the firm’s Luxembourg office, while Mark Brown has joined the firm’s London office, strengthening the firm’s capabilities across key European financial hubs.
Møller joins from Simmons & Simmons, where she led the Regulatory practice and built a pan-European financial services regulatory advisory practice. Her client base includes financial institutions, insurance companies, fintech firms, and crypto-asset service providers, as well as other financial-sector participants.
Her practice focuses on traditional banking and payment services, investment activities, product regulation, and financial promotion. She advises clients across major regulatory frameworks, including MiFID, CRD6, Crowdfunding, PSD3, DORA, and MiCA, as well as tokenisation, licensing, and perimeter issues. With extensive relationships with regulators and experience in financial services transactions, she advises clients navigating evolving regulatory frameworks and market developments.
Brown brings more than two decades of experience advising companies on structured products, derivatives, and securities lending, as well as regulatory advisory and bank reorganization projects. His work includes M&A mandates, ESG policy development, and complex cross-border legal matters. Prior to joining the firm, Brown spent many years as a partner at Linklaters and most recently served at the UK’s Financial Conduct Authority as a Policy Technical Specialist within the Infrastructure and Exchanges Directorate – Capital Markets Group and the Sustainable Finance Division.
His career also includes work across multiple international markets, including Tokyo and Hong Kong, before returning to London. At DLA Piper, he will help strengthen the firm’s structured finance and derivatives capabilities.
The hires form part of a broader expansion within the firm’s Financial and Capital Markets practices. In recent months, DLA Piper has added several partners globally and advised major clients across large financing and capital markets transactions, including advising Banco Santander on a EUR1.4 billion warehouse financing facility for Klarna, assisting Astra Partners in securing a EUR340 million financing facility, and advising Danaher Corporation on a CHF1.25 billion bond offering.
