Thermo Fisher Scientific ( TMO) is a staple name in laboratories across the globe - the firm supplies a massive catalog of scientific instruments, laboratory equipment, and consumables to customers in the life-science, health care and environmental science industries. In all, Thermo Fisher boasts more than 350,000 customers spread all over the globe. TMO's business differs from, say, an office supply company because the firm's offerings reach far higher up the value chain -- TMO isn't merely a supplier, it also develops the scientific instruments that it sells. The firm's high-end mass spectrometry equipment, for example, leads the industry in sales, giving TMO a big advantage in selling the more commoditized consumables that it offers. International sales are a big opportunity for TMO as firms in other countries ramp up their laboratory presence. Because Thermo Fisher already owns inroads into markets like China and India, it's among the best positioned to supply those markets. Thermo Fisher's balance sheet has a reasonable amount of leverage for a firm that operates in a capital-intense business. More importantly, TMO throws off significant cash from its operations, enabling it to build up a $1 billion safety net.
