Amy Marlyse Plato joined Motiva in January 2020 as Motiva's Executive Vice President, General Counsel, Secretary, and Business Compliance Officer. Since then, she has been instrumental in aligning Motiva's legal obligations with its business compliance activities.

To further manage Motiva's reputational risks, streamline responsibilities, and ensure important checks-and-balances are in place among the various roles involved in Motiva's external stakeholder engagement, Amy's role has expanded over the course of her tenure with Motiva. She is currently responsible for Legal; Compliance; Tax Advisory and Planning; Stakeholder Relations, including Environmental, Social, and Governance (ESG) and Product Compliance and Stewardship; Public Affairs, including Communications and Social Responsibility and Community Affairs; and Records Management.

At Motiva, Amy has been responsible for delivering key transactions that are positioning the company to be agile as it strives to be the world’s safest and most profitable downstream company and an integral part of Aramco’s Downstream business. In 2022 she oversaw the acquisition of Motiva Trading LLC by a newly formed subsidiary of Aramco Trading Company and in 2023 oversaw the sale of Motiva’s 25 clean product terminals to Global Partners LP.  

Prior to joining Motiva, Amy served as primary corporate counsel for Aramco Services Company's (ASC) subsidiary Saudi Refining, Inc. (SRI) in conjunction with SRI's distribution of assets and liabilities out of its joint venture with Shell and Motiva. Her expertise comes from the 17 years spent as a litigation partner, trying complex commercial cases to juries and arbitral panels ― including claims of bank fraud, securities fraud, and RICO ― before moving into complex transactions such as mergers and acquisitions, divestitures, and dissolutions. She has also managed corporate governance issues and overseen federal regulatory filings for ASC and its affiliates.

Amy received her Bachelor of Arts from Dartmouth College and her Juris Doctorate from The University of Texas School of Law. She is licensed to practice in the state of Texas and before the U.S. Supreme Court, U.S. Courts of Appeals for the Fifth, Eighth, and Federal Circuits, as well as the U.S. District Courts of the Northern, Eastern, Southern, and Western Districts of Texas.
