Exhibit 99.1

NEWS RELEASE

COLUMBUS, Ohio, November 18, 2019 – Alliance Data Systems Corporation (NYSE: ADS), a leading global provider of data-driven marketing and loyalty solutions, today announced that Ralph Andretta has been named president and chief executive officer of the Company, effective February 3, 2020. Andretta joins Alliance Data from Citigroup, where he most recently served as managing director and head of its U.S. cards business. He succeeds Melisa Miller, who served in the role following the June 2019 retirement of long-time president and CEO Ed Heffernan.  Mr. Andretta will also join the Alliance Data board of directors at the time he assumes the CEO role.  Charles Horn, vice chairman of Alliance Data, will serve as acting CEO pending the effective date of Mr. Andretta’s appointment.

“As Alliance Data follows through on its business transformation, I want to thank Melisa Miller for her commitment and dedication to the Company and her invaluable contribution to the growth of our card business,” said Alliance Data Board Chairman Rob Minicucci.

“Today’s announcement reflects an opportunistic but carefully considered board decision. Earlier this year, the board initiated an executive search for a newly-created chief operating officer position. Consistent with board succession planning, the candidate selected as COO was intended to be positioned as successor to the Alliance Data CEO,” continued Minicucci.  “As board members came to know Ralph Andretta and understand the breadth and depth of his card business experience, operational leadership strength and financial expertise, it became apparent that Ralph was an exceptional fit for the immediate strategic needs of Alliance Data and the interests of its investors, clients and associates. Hence, a decision was made by the full board to appoint Ralph as the Company’s new CEO.  Pending Ralph’s arrival, Charles Horn will continue driving initiatives aimed at streamlining Alliance Data’s cost structure and operating model while overseeing the Company as acting CEO, and Melisa will serve in an advisory role during this interim period.”

Prior to his position as head of U.S. cards for Citi, Andretta held positions as head of loyalty, co-brand and product development for Citi. At Bank of America, he was a global affinity products and international card executive after spending 18 years with American Express, where Andretta’s portfolio included the U.S. consumer card business, membership rewards, insurance sales and services, global internet sales and services, product development and re-engineering.

“I am both excited and honored to take on this new role with Alliance Data,” said Ralph Andretta.  “Having worked in many capacities across major financial institutions, I recognize the uniqueness of Alliance Data’s business model, data-driven centricity and go-to-market approach.  I appreciate the board’s confidence in my abilities to lead the business, particularly during such an exciting, transformative time, and I look forward to working alongside the Company’s talented associates across its lines of business to return to consistent, sustainable earnings growth.”

The guidance provided in Alliance Data’s third quarter earnings release on October 24, 2019, remains unchanged.
