CHICAGO — Two months into his tenure as chief executive officer of Archer Daniels Midland Co., Juan Luciano is not afraid to shake things up. Mr. Luciano on March 2 unveiled a number of changes to the company’s management makeup.

“To accelerate the execution of our strategic plans, we need teams that can quickly flex and form to identify and capture opportunities, focus on what matters, deliver results, and then re-form to address the next set of opportunities,” Mr. Luciano said. “To that end, I have formed some new teams and expanded the responsibilities of some key leaders.”

Ray G. Young has been named executive vice-president; he remains the company’s chief financial officer and will add responsibility for oversight of ADM’s business in Asia. He joined ADM in 2010 following a 24-year tenure with General Motors Co., during which he held executive leadership positions in finance, general management, planning and operations on four continents.

“Ray’s exceptional insight into the region will allow him to assist Ismael Roig, the president of ADM Asia-Pacific, and our other regional leaders as they accelerate our Asia strategy,” Mr. Luciano said.

Mark A. Bemis, senior vice-president, will become president, North America, and chair a new Geographic Council that brings together ADM’s regional presidents to ensure the company is leveraging best practices across each geography. He joined ADM in 1983 and has held a number of positions, including president of ADM’s Corn Processing business, president of ADM’s Cocoa, Milling, and Financial Services businesses, and vice-president and general manager for ADM Cocoa North America. In addition, he has held various merchandising and management positions in the company’s Agricultural Services, Malt, Corn Processing, and Oilseeds Processing businesses. He became a vice-president of the company in 2005 and a senior vice-president in 2010.

“Our geography leaders will help our businesses achieve strong P/L performance by providing them with efficient regional S.G.&A. cost positions — through optimal organizational design — and by presenting good growth opportunities for business consideration,” Mr. Luciano said. “As president, North America, Mark will be responsible for finding new pockets of growth in the U.S. and expanding our presence in Mexico and Canada. Mark has just led our Corn team to some of its highest performance on record and, with his deep knowledge of the company’s businesses and operations, he is uniquely suited to perform these roles.”

Christopher M. Cuddy will become president of ADM’s Corn Processing business unit. Previously, Mr. Cuddy was president, Sweeteners and Starches, in ADM’s Corn Processing business unit. He joined ADM in 1998 and has held a variety of merchandising and management roles prior to leading the sweeteners and starches group, including president, Almidones Mexicanos, SA de CV (Almex), an ADM joint venture based in Guadalajara, Mexico. Before that, Mr. Cuddy was vice-president, ADM Corn Processing. From 2000 to 2004, he was North American sales manager, ADM BioProducts. He began his career with the company as a senior commodity trader with ADM Grain.

“Chris has a great track record of success within Corn, with the vision and initiative to take on challenges and deliver results,” Mr. Luciano said. “Mark and Chris have been a strong team, and I know they will work together very successfully to accomplish a smooth transition.”

Todd Werpy will take on an expanded role as chief technology officer. Previously, Dr. Werpy was ADM’s senior vice-president of research and development. Prior to joining ADM in 2007, he spent 15 years at Pacific Northwest National Laboratory, where he was responsible for research and business development for new chemicals and chemical intermediates from renewable feedstocks. Dr. Werpy developed the catalytic technology being commercialized by ADM for the conversion of glycerin and sorbitol to propylene glycol. He holds 30 U.S. patents in the area of catalysis and chemical conversion of biomass to chemicals. He was selected as the recipient of the 2015 American Chemical Society Award for Affordable Green Chemistry.

“Todd will expand his work to ensure that technology delivers cost improvements and competitive advantage, and that we deliver on the strong pipeline of improvement projects,” Mr. Luciano said. “As chief technology officer, he will also ensure we have the right focus and resources to support the rejuvenation of our product mix through product innovations across our value chain — a key driver of organic growth.”

Vikram Luthar has been named senior vice-president of strategy. Mr. Luthar also is chief financial officer for the company’s Corn business unit and an officer of the corporation. Previously, he was ADM’s group vice-president of finance, with oversight of ADM’s global treasury and credit operations. He joined ADM in 2004 as vice-president and treasurer. Prior to that, he spent 11 years with General Motors Co., serving in various treasury and corporate finance positions in the United States and Asia.
