Bellum Medical is not currently listed and is not a Fortune 500 company. The Fortune 500 requires all companies on the list to publish their financial data and submit some or all of their figures to a government agency. Figures are based on individual company reports, with comparisons based on the previous year's figures as originally reported. Since the vast majority of unlisted companies do not release their financial figures to the public, the vast majority of companies on the table are listed. But there are still exceptions such as State Grid and Petroleos de Venezuela.
Founded in 1839 and headquartered in Melsungen, Germany, Beltronic is one of the world's largest suppliers of specialized medical equipment, pharmaceutical products, and surgical medical devices.
