The uncertainties over the emergence and spread of the conflict have caused market volatility worldwide. Antin and its portfolio companies have no direct or indirect exposure to the conflict in Russia and Ukraine and have no physical locations in those regions. Antin also has no fund investors based in Russia or Ukraine. Antin will continue to monitor the situation and potential effects it may have on the business and its portfolio companies.
