Midland, Michigan-based Dow Chemical Co. (NYSE: DOW – $53.60) has hired Morgan Stanley to sell its Angus Chemical and AgroFresh units, two specialty chemical divisions, which could bring the company about $2 billion. Dow has been shedding non-core businesses in an effort to concentrate on higher-margin products such as agriculture, plastics, films and other performance chemicals. Separately, Dow’s Microbial Control unit has entered into a commercial agreement with food safety company Xgenex LLC, for U.S. sales of Dow’s sanitization system for food processing and packaging environments. Dow’s Advanced Oxidation System – Certified Whole Room Sanitization – aims to reduce and control pathogens on surfaces and in the air. The system, developed specifically for the food industry, creates ozone vapor on demand using ambient air and water. Shares of DOW have good total return potential for the pull to late decade. This should be supported by healthy growth in share earnings in the coming years aided by a $4.5 billion buyback program and with moderate top line improvements. The shares also carry a well covered annual dividend of $1.48 per share, yielding 2.8%, at current levels.
