Kathy Warden’s career at Northrop Grumman
Kathy J. Warden joined Northrop Grumman in 2008 after holding leadership positions at companies including General Dynamics and General Electric.
At Northrop Grumman, she moved through several senior management roles. She led the company’s Information Systems business and later its Mission Systems division before becoming president and chief operating officer in January 2018.
One of her significant responsibilities during this period involved the integration of Orbital ATK, an aerospace and defense company acquired by Northrop Grumman in June 2018.
The acquisition expanded Northrop Grumman’s space and defense operations. Warden’s involvement in integrating the business illustrates the operational responsibilities she held before becoming chief executive.
She became CEO and president on January 1, 2019, followed by her appointment as board chair in August of the same year.
According to Northrop Grumman’s official leadership biography, Warden’s professional background includes corporate strategy, business operations and major organizational integration.
Her appointment history is also documented in the company’s 2026 proxy statement.
As of October 2026, Warden continues to hold Northrop Grumman’s chair, CEO and president positions.
María Asunción Aramburuzabala’s business background
María Asunción Aramburuzabala Larregui is a Mexican investor whose business career is closely associated with Grupo Modelo, the brewing company behind internationally recognized beer brands.
Her family held significant interests in Grupo Modelo. Following her father’s death in 1995, Aramburuzabala became more involved in managing the family’s business interests.
She subsequently developed Tresalia Capital, an investment organization established in 1996. Its activities have included investments in consumer businesses, technology and other sectors.
A major development in her business history came when Anheuser-Busch InBev completed its combination with Grupo Modelo on June 4, 2013, following an agreement announced in 2012.
The transaction marked a significant change in Grupo Modelo’s ownership structure, while Aramburuzabala’s investment activities extended beyond the brewing industry.
Her professional experience also includes corporate governance positions. She previously served on the boards of AB InBev and Coty, leaving those positions in 2023 and February 2025, respectively.
According to a March 2026 announcement by ITAM, where she studied public accounting, Aramburuzabala remains president of Tresalia Capital.
Her current position should not be confused with the firm’s day-to-day chief executive role. Bloomberg reported in June 2025 that former Goldman Sachs executive Rodolfo Pérez had assumed the CEO position while Aramburuzabala retained her leadership role as president or chair.
Is there a connection between Kathy Warden and María Asunción Aramburuzabala?
There is no publicly established direct relationship between Kathy Warden and María Asunción Aramburuzabala.
Their documented business activities centre on different companies, industries and professional responsibilities. Northrop Grumman’s corporate disclosures identify Warden’s leadership positions, while records from Tresalia-related business coverage, Coty and AB InBev establish Aramburuzabala’s professional background.
These records do not establish a shared board appointment, joint company, business partnership or family connection involving the two women.
That does not prove they have never met or interacted privately. It means there is no confirmed public basis for describing them as personally or professionally connected.
The meaningful comparison is between their careers. Warden advanced through corporate management before becoming the chief executive of a major American defense contractor. Aramburuzabala developed an investment business from a longstanding Mexican family enterprise.
As of October 2026, their principal professional roles remain distinct: Warden leads Northrop Grumman, while Aramburuzabala serves as president of Tresalia Capital.
