FOREIGN INVESTMENT CONTROL (FIC/FDI)
Navigating foreign investment controls: a strategic and integrated approach
The multiplication of foreign investment screening regimes, their continuous expansion into new sectors, from defense throughout critical infrastructures to healthcare and new technologies, as well as increasing coordination and emulation among authorities across the European Union and beyond have made foreign investment screening processes a key element of many M&A transactions, from the perspective of transaction certainty and deal economics, along merger control and more recently the European foreign subsidies regulation.
An experienced, multidisciplinary team
Our Foreign Investment team, made up of experts in mergers & acquisitions, competition law, international trade/ sanctions and public law, mobilizes the full range of our firm's expertise to provide targeted, pragmatic advice.
Our track record in M&A and long-standing experience advising foreign investors with regard to strategic investments in France and French clients in their investments abroad allow us to anticipate and appropriately address regulatory hurdles and business impacts linked to foreign investment screening processes, be it in the context of investments primarily aimed into France or multi-jurisdictional transactions.
Expertise valued by the authorities
We maintain continuous and constructive working relations with the Office for Screening of Foreign Investments into France at the Ministry of Economy and other relevant stakeholders.. Our lawyers are regularly consulted on legislative developments, enabling us to anticipate risks and shape effective notification strategies.
A global vision of screening mechanisms
Via our closely knit network of partner firms with a truly global reach, we are fully equipped to conduct regulatory analysis and filings across any required jurisdictions (EU Member States having implemented screening mechanisms, the US (CFIUS), the UK National Security and Investment Act and beyond), either under French regulations or as lead counsel coordinating filings across all jurisdictions.
Our support also covers related issues, including national security compliance, export control/ sanctions and procurement/ government contracts.
STOCK MARKET LITIGATION
Jeantet works on behalf of its individual and corporate clients beginning at the initial AMF investigation stage, and supports them through any administrative proceedings conducted by AMF’s Board and Sanctions Committee. These proceedings are often based on a criticism with regard to the timing or quality of publicly reported information, or even the alleged existence of market abuses (dissemination of false information, insider trading violations, market manipulation, etc.)
On a broader level, we assist our clients (issuers, majority and minority shareholders, investors, company executives, financial brokers) throughout the course of any litigations featuring a “stock market” dimension, meaning those with public shareholders, shareholder disputes (abuse by majority shareholders, governance issues), and even specific regulations (takeover bids, AMF Doctrine, “golden parachutes,” etc.).
For all of these disputes, we have developed an expertise based on the decompartmentalization of jurisdictions (corporate law, stock exchange regulations, civil and/or criminal proceedings) in conjunction with the firm's other teams (financial regulation, labor law, collective proceedings). To cite one example,
we have submitted to the Constitutional Council a Priority Question of Constitutionality (QPC) based on the Declaration of the Rights of Man and of the Citizen of 1789 in a case involving the crossing of thresholds by an action in concert.
DISTRESSED M&A
The takeover of a company placed in the context of insolvency proceedings cannot be handled under M&A rules. Our cross-functional approach to cases and the expertise of our Restructuring and M&A lawyers enable us to assist our clients in dealing with these specific situations and the complex issues that arise therefrom.
CORPORATE LITIGATION
We combine our knowledge of complex transactions with a strong litigation practice and provide our support and expertise to you, executives and companies, by developing a personalized legal strategy to defend your interests.
- Conflicts between shareholders;
- Liability of directors for mismanagement;
- Post-acquisition litigation;
