Five Investor Relations Practitioners in GovCon


Five Investor Relations Practitioners in GovCon

The role of investor relations has been rapidly evolving due to regulatory updates, new technologies and an unpredictable market. As MZ Group pointed out, new digitalization trends have forced investor relations professionals to adapt their communication styles to meet the demands of their growing audiences.  

In addition, investors have more prominently been pushing environmental, social and corporate governance agendas in an effort to better foster sustainability and ethicality. It is the investor relations practitioner's responsibility to maintain the ties between his company and its most important stakeholders.  

The Potomac Officers Club – a division of Executive Mosaic – features five executives leading the investor relations practices at some of the most prominent government contracting companies.
