Wall Street Journal: DowDuPont Inc. today raised its forecast for cost savings from its push to divide itself into three companies and updated its timeline to complete the process. The chemical giant, formed from the August merger of DuPont Co. and Dow Chemical Co., said it expects moves to cut jobs and change its facility footprint to save $3.3 billion in annual costs, up from its previous guidance of $3 billion. Its plan to split into three companies — which will be focused on specialty-chemical products, materials and agriculture — was supposed to take up to two years. Today, the company said the process will take 14 to 16 months. The ag company to be created would include Johnston-based DuPont Pioneer.
