FRAUD ALERT - VIGILANCE REQUESTED

The Sienna Investment Managers Group would like to draw your attention to the risk of identity usurpation by fraudsters inciting individual investors to invest in fraudulent financial investments. The companies of the Sienna Investment Managers Group do not approach individual investors directly and therefore we ask you to exercise the utmost vigilance by not responding to any investment solicitations via e-mail, telephone calls or social networking/instant messaging. If you have made a payment to a scammer, contact your bank immediately to block the transfer or request the return of the funds paid. You can report these practices via the government website: www.internet-signalement.gouv.fr

Investing in European sovereignty

Scroll

«  European sovereignty does not mean taking power away from states, but giving it back to Europe ».

In a context of intense geopolitical tensions, rapid technological advances, and disruptions in supply chains, Europe can no longer be content with a mere role as arbitrator. It must become an active player again. Investing in European sovereignty means choosing a model that protects our citizens, enhances our capacity for innovation, and strengthens our energy, technological, and industrial autonomy. It enables our companies, SMEs, mid-sized enterprises, and large groups to develop concrete solutions to meet the challenges of tomorrow.

Because sovereignty is not a step backward but a real lever for progress, it is time to decide, protect, and invest together to build a more resilient, ambitious, and forward-looking Europe.
