Ryder System, Inc. announced the appointment of John J. Diez to Executive Vice President and Chief Financial Officer. Diez succeeds Scott T. Parker, who resigned from his position to pursue other opportunities and will remain with Ryder through June 4, to ensure a smooth transition.

Diez, most recently President of Ryder’s Fleet Management Solutions (FMS) business, will oversee all of Ryder’s financial management functions including finance and accounting, treasury, tax, audit, corporate strategy and investor relations.

During his 20-year tenure at Ryder, Diez has held a variety of senior operational and financial management roles with increasing responsibility. Prior to serving as president of Ryder’s FMS business, he was president of the company’s Dedicated Transportation Solutions (DTS) business unit where he led strong revenue growth and improved business returns. In addition, Diez has extensive industry and finance experience, having served as Ryder’s Senior Vice President of Field Finance, CFO for the FMS business segment, Senior Vice President of Asset Management, and Assistant Controller for the company. Prior to joining Ryder in 2002, Diez began his career in the audit practice of KPMG LLP. Diez is a licensed Certified Public Accountant.

As part of this organizational change, Tom Havens, most recently Senior Vice President and Global Chief of Operations for the FMS business since 2012, has been named president of Ryder’s FMS business unit. With this promotion, Havens joins Ryder’s executive leadership team and reports to Ryder Chairman and Chief Executive Officer Robert E. Sanchez.

Havens is a 28-year veteran of Ryder. Over the course of his Ryder career, he has held a variety of positions of increasing responsibility, including Head Of Operations for Ryder’s west region, General Manager for FMS in Canada, Vice President of Asset Management and Vehicle Sales, and numerous positions in the rental organization where he started as a rental representative in 1993.

“I am pleased we were able to fill these critically important and strategic roles with extremely talented business leaders from within the company,” said Sanchez. “Both John and Tom have strong track records in understanding the unique needs of our company, while delivering transformational finance and business performance results.”

“On behalf of Ryder, I would like to thank Scott for his passion and drive for our financial performance, positioning us well for the future,” added Sanchez. “We wish him all the best in his future endeavors.”
