Type two powerful women leaders into a search box and you expect to find a shared board, a shared deal, or at least a shared stage. With Kathy Warden and Maria Asuncion Aramburuzabala, there is almost nothing shared at all, and that near-empty result is itself the story. One is the chief executive who runs Northrop Grumman, one of America’s largest defense contractors, building bombers and missiles. The other is the Mexican heiress who turned a beer fortune into a multi-billion dollar family investment office. They work on different continents, in different industries, in different currencies of power. What links them is a search query, a leadership list, and a question no existing page answers properly: who is richer, and by how much?
This article is the first paired piece about them that answers that question with labeled numbers instead of dodging it. It starts with the connection truth, then gives you the comparison you actually came for, with every figure sourced and every estimate labeled as an estimate.
A note on photos before we start: the images in this article are illustrative stock photos. They are not photographs of Kathy Warden or Maria Asuncion Aramburuzabala, and no caption here should be read as suggesting otherwise.
Are They Connected? The Honest Answer First
No. There is no documented personal relationship, partnership, shared company, shared board seat, joint deal, or meeting between Kathy Warden and Maria Asuncion Aramburuzabala. Warden’s boards are Northrop Grumman, Merck, Catalyst, the Greater Washington Partnership, and the Federal Reserve Bank of Richmond. Aramburuzabala’s boards were Grupo Modelo, AB InBev until 2023, and Coty until 2023. There is zero overlap. Their industries do not touch: American defense and aerospace on one side, Mexican beer and diversified investment on the other. Anyone who tells you they are partners, or related, or business allies, is inventing a story to fill a keyword.
The One Link Between Kathy Warden and Maria Asuncion Aramburuzabala
The only shared appearance found anywhere is list-based, and this article will say so plainly rather than dress it up. Both women appear on the 2023 House of Rose list of inspirational women in leadership across the Americas, published by FairPlayTalks in January 2023. That is a list, not a relationship. They appear separately on it, for separate achievements, in separate countries. There is no company bridge here like the 1997 Microsoft and Comcast investment in an earlier article in this series. There is no deal, no board, no event that ties them. The honest version of this pairing is a contrast, not a connection, and the rest of this article is built on that contrast.
Who Is Kathy Warden?
Kathy Warden was born around 1970 in Smithsburg, Maryland, and she was the first person in her family to go to college. She earned a bachelor’s degree in computer information systems from James Madison University in 1992 and an MBA from George Washington University in 1999. She spent nearly a decade at General Electric in commercial industries, held leadership roles at General Dynamics and Veridian, and worked as a principal in a venture internet firm before joining Northrop Grumman in 2008.
From Smithsburg to the Chief Executive’s Chair
Warden climbed through Northrop’s operating side: president of the Mission Systems and Information Systems sectors, then president and chief operating officer, then a seat on the Northrop board in 2018. She became chief executive and president on January 1, 2019, succeeding Wes Bush, and added the chairman’s role on August 1, 2019. She still holds all three titles in 2026, confirmed by October 2026 coverage and the company’s third quarter 2026 earnings call. Outside Northrop she sits on Merck’s board, joined March 16, 2020, chairs Catalyst and the Greater Washington Partnership, and has chaired the Federal Reserve Bank of Richmond’s board. Her honors include the Deming Cup for Operational Excellence in 2022, a Yale Legend in Leadership Award, CNBC Changemaker status in 2025, and a place at number 68 on Fortune’s Most Powerful Women list in 2025.
The 2026 Defense Boom
Warden’s 2026 is a year of record orders and expensive programs. Northrop reported third quarter 2026 revenue of $11.1 billion, up 7 percent year on year, a record backlog of $110 billion with a book-to-bill ratio of 1.5, and raised its 2026 sales forecast to as much as $44.25 billion. Full year 2025 revenue was about $42 billion with about 95,000 to 100,000 employees and net earnings of $4.18 billion. The company’s market value was about $78.2 billion at a share price of $557.54 on October 30, 2026.
The programs behind those numbers are the ones that dominate her tenure. The B-21 Raider stealth bomber was unveiled in December 2022 and first flew in November 2023, but it has cost Northrop dearly: a $1.56 billion loss provision in the fourth quarter of 2023 plus $477 million more in the first quarter of 2025, even as 2026 federal funding of $4.5 billion was approved to speed production. The Sentinel intercontinental ballistic missile program saw its cost rise 81 percent over the original $77.7 billion estimate, according to the Pentagon in July 2024, survived a formal review, and is now targeted for a first flight in 2027. In October 2026 Northrop definitized 12 additional Virginia-class submarine propulsion shipsets, adding $1.4 billion to backlog. The company also contributed to the James Webb Space Telescope and integrated the Orbital ATK acquisition. Warden’s job is to turn that backlog into profit while the big programs keep testing her margins.
Who Is Maria Asuncion Aramburuzabala?
Maria Asuncion Aramburuzabala Larregui was born on May 2, 1963, in Mexico City, and is known to friends as Marisun. She studied accounting at ITAM, the Instituto Tecnologico Autonomo de Mexico. Her grandfather Felix Aramburuzabala co-founded Grupo Modelo in 1925 in Mexico City after emigrating from the Basque Country, and the company behind Corona beer became one of Mexico’s great family businesses. Her father Pablo Aramburuzabala was Grupo Modelo’s executive vice president. When he died of cancer in 1995 at age 63, there was no finalized succession plan, and his 32-year-old daughter, raising two young sons, walked into a boardroom fight over the family stake.
The 1995 Inheritance Crisis
Aramburuzabala became vice chair of Grupo Modelo in 1996 and spent the following years defending and consolidating the family’s position. The decisive moment came in June 2013, when AB InBev bought the remaining 50 percent of Grupo Modelo for about $20 billion. She helped convince other shareholders to approve the deal after AB InBev raised its offer, and the family pocketed at least $3 billion through Grupo Modelo stake sales, according to Bloomberg. She used part of the proceeds to buy AB InBev shares and joined its board, alongside Valentin Diez Morodo, another Modelo co-founder descendant. She stepped down from the AB InBev board and from Coty’s board, both in 2023, and now focuses on her investment office plus her hobbies, which include travel, animal photography, and deep-sea diving.
Tresalia: From Beer Money to a Diversified Fortune
In 1996, the same year she became Grupo Modelo’s vice chair, Aramburuzabala founded Tresalia Capital with her mother and sister. The name comes from “Tres Aliadas,” three allies. She ran it as chief executive from 1996, and in recent years she has stepped back from day-to-day duties while keeping the chair role. Rodolfo Perez, a former Goldman Sachs banker recruited about three years before mid-2025, succeeded her as chief executive. Other senior hires include Antonio Gonzalez Anaya, a former Credit Suisse banker, as head of research during the pandemic, and Bruce Zimmerman, a former chief investment officer of Ray Dalio’s family office, as investment director in 2024. Succession planning is now explicit: Bloomberg’s June 30, 2025 piece frames it as making sure the 1995 crisis does not repeat, and her elder son Pablo is a managing director at Tresalia overseeing private equity.
Tresalia’s portfolio shows how far the money has traveled from beer. It has invested in Grupo Televisa, Tory Burch, Casper, KIO Networks, the data center company it backed from founding and agreed to sell to I Squared Capital in 2021, Abilia, its real estate arm behind the Parques Polanco development in Mexico City, Kraft Heinz, JAB Holding, Artega Motors, Kavak, and Luuna. That diversification is the whole point of the office: a single-industry inheritance, spread across industries and countries over thirty years, so that no single crisis can repeat 1995.

Kathy Warden Net Worth: Salary, Stock, and the Tracker Problem
Warden’s wealth has no authoritative total, but the stale tracker pages, CEO.wiki’s $60 million as of December 2024 and HousingMarketNews’ about $45 million, sit far below what her 2026 filings support.
The anchor comes from Hargreaves Lansdown director-dealings data based on FactSet. Her reported share counts sit in the roughly 176,000 to 197,000 range across early 2026 filings: 190,778 shares remaining after a February 11, 2026 tax-related sale at $678.83, and 176,460 after a February 6, 2026 sale at $709.49. At the October 30, 2026 price of $559.25, that is roughly $98 million to $110 million in stock alone. At February 2026 prices it is roughly $120 million to $140 million. The counts vary by filing and tranche, so this article gives a range, not one number. She sold about $20.2 million of stock in early 2026, including a largest single sale of $14.18 million, 20,000 shares at a $708.82 average, filed February 10, 2026, plus tax-related sales. Those are normal executive sales, not a signal of anything.
Her documented pay is $22.5 million for 2023, per CEO.wiki. Fidelity’s key-personnel table lists a salary of $1.84 million and total compensation of $25.36 million, but the snippet does not state the year, so this article presents it as Fidelity’s listed figure, not as a dated proxy figure. On August 19, 2026, Northrop granted her a one-time performance-based award of 35,910 market stock units, paying out 0 to 150 percent based on absolute stock price performance through December 31, 2031, zero if the stock falls more than 25 percent, 150 percent if it rises at least 50 percent, with the target requiring at least 10 percent appreciation, per the August 21, 2026 8-K as summarized by TradingView. Put it together and the honest 2026 figure is about $100 million to $140 million, holdings anchored, before cash, prior sales, and unvested awards, and no authoritative total exists.
Warden’s Holdings at Late-October Prices
At late-October 2026 prices of $557 to $559, Warden’s disclosed Northrop stake is worth about $96 million to $110 million, on disclosed counts of about 172,000 to 197,000 shares. Finnhub’s October 30, 2026 close for Northrop (NOC) is $557.54 with a market cap of about $78.2 billion. A February 11, 2026 report of her February 6, 2026 sale of 20,000 shares at $705.84 to $711.14 leaves her stake at 171,602.4 shares. Across 2026 prices, her headline range is about $95 million to $140 million: February 2026 prices of $678 to $709 support the top end, and late-October prices support the low end.
Maria Asuncion Aramburuzabala Net Worth: A Family Fortune, Honestly Labeled
Aramburuzabala’s wealth is far better documented, but it carries a label that matters. Forbes’ 2026 Billionaires List, published March 10, 2026, puts her at $9.3 billion, rank number 372 in the world, the only Mexican woman on the list and Mexico’s richest woman. Forbes’ real-time tracker on October 30, 2026, still showed $9.3 billion, rank number 392. The Bloomberg Billionaires Index, in its first-time valuation on June 30, 2025, put her at $8.2 billion, the second-richest woman in Latin America after Chile’s Iris Fontbona. LatiNation in 2025 put her at $9 billion, up $2.7 billion in a single year. The trajectory is the story: about $5.6 billion in 2021 to $9.3 billion in 2026.
The older figures still circulating need to be labeled as stale, not repeated as current. Celebrity Net Worth’s $5.6 billion was last updated in February 2021. Memesita’s $6.3 billion dates to April 2025 and predates the Forbes 2026 jump. One site’s year table projecting $7.5 billion for 2025 is unsourced projection, not reporting. This article rejects those as current figures and anchors on Forbes 2026 and Bloomberg 2025.
One more honesty point, and it is important. Forbes lists the fortune as “Maria Asuncion Aramburuzabala and family.” That means $9.3 billion is a family fortune, not a purely personal bank balance. The family’s money is managed through Tresalia, the succession is being planned in public, and the figure belongs to the family office as much as to one woman. This article keeps that label attached every time the number appears.
The Verdict: Who Is Richer, and by How Much?
Maria Asuncion Aramburuzabala, by an enormous margin. On the best-grounded figures, about $9.3 billion against Warden’s holdings-anchored roughly $95 million to $140 million, she is roughly 65 to 100 times richer. Against the stale $45 million to $60 million tracker figures for Warden, the gap stretches further, up to about 150 to 200 times. The fair headline is that Aramburuzabala is richer by roughly 65 to 100 times on current filings, with the caveat that her figure is a family fortune estimate and Warden has no authoritative total. Unlike the close calls in some earlier articles in this series, this one is not close at all. It is nearly two orders of magnitude, and no honest reading of the filings closes it.
Hired Executive Versus Born Heiress: Two Routes to the Top
This is the most useful contrast in the whole comparison, and no competitor page writes about it, because no paired page exists at all. Warden took the hired route: the first person in her family to go to college, a decade at General Electric, leadership roles at two more contractors, then eighteen years climbing inside Northrop Grumman, from sector president to the chief executive’s chair. Her wealth is professional equity, accumulated one vesting cycle at a time, with no family block and no inheritance. Her risk is the job itself: her fortune depends on Northrop’s share price and on staying in a role where the board can replace her.
Aramburuzabala took the inheritance route, and it was not the easy version of it. She did not receive a fortune in an envelope. She received a contested stake, a dead father’s unfinished succession plan, two young sons, and a boardroom fight, at age 32. Her wealth is family equity, defended first, then sold at the right moment in 2013, then diversified through Tresalia over thirty years so that no single industry could take it away again. Her risk is different: a family fortune must survive generations, tax, and the next succession, which is exactly why she is planning this one in public. One route rewards persistence inside a company. The other rewards survival inside a family. Both arrived at the top of business in the Americas, but only one of them arrived a billionaire, many times over.
What Each Is Doing in 2026
Warden’s 2026 is a year of backlog and big bets. The record $110 billion backlog, the B-21 production ramp with its $4.5 billion in 2026 federal funding, the Sentinel program pushing toward a 2027 first flight, and the October 2026 Virginia-class propulsion order all sit on her desk at once. The August 2026 performance stock award ties her own pay to Northrop’s share price through 2031, which means her fortune now rises or falls with the same programs she is defending. The open question is whether the backlog converts into profit fast enough to satisfy investors who have watched the B-21 and Sentinel costs climb. In February 2026, Northrop and Poland’s Niewiadow-PGM entered a framework agreement to make 155-millimetre artillery shells in Poland, with no financial details disclosed.
Aramburuzabala’s 2026 is a year of handing over. She remains Tresalia’s chair while Perez runs the office day to day, her elder son Pablo works inside it as a managing director over private equity, and the succession plan Bloomberg described in 2025 moves from paper to practice. She stepped off the AB InBev and Coty boards in 2023, and the office she built from beer money now invests across media, real estate, data centers, and consumer brands. The open question is whether the second generation keeps the fortune growing or merely preserves it, and the answer will take a decade to see. Forbes’ 2026 profile notes that Aramburuzabala continues preparing the next generation to participate in the family business future.

What is the connection between Kathy Warden and Maria Asuncion Aramburuzabala?
There is no personal or business connection. No shared company, shared board seat, joint deal, or meeting has been documented.

Maria Asuncion Aramburuzabala, by an enormous margin. On the best-grounded figures, her roughly $9.3 billion against Warden’s roughly $95 million to $140 million puts her about 65 to 100 times richer, and the fair headline range is roughly 65 to 100 times on current filings.
What is Kathy Warden’s net worth?
There is no authoritative total. Tracker pages give $45 million to $60 million, but those figures look stale against her 2026 filings. Her documented Northrop stock holdings alone are worth roughly $98 million to $140 million depending on date and share price, so the honest 2026 range is about $100 million to $140 million, holdings anchored, before cash, prior sales, and unvested awards.

Her documented pay is $22.5 million for 2023, per CEO.wiki. Fidelity’s key-personnel table lists a salary of $1.84 million and total compensation of $25.36 million, but the snippet does not state the year, so it should not be quoted as a dated proxy figure. In August 2026 she also received a one-time performance stock award of 35,910 market stock units tied to Northrop’s share price through 2031.
How did Maria Asuncion Aramburuzabala become a billionaire?
She inherited a stake in Grupo Modelo, the Corona beer company her grandfather co-founded, defended it after her father’s death in 1995 left no succession plan, helped approve AB InBev’s roughly $20 billion purchase of the remaining half of Grupo Modelo in 2013, and diversified the proceeds through her family investment office, Tresalia Capital, over thirty years.
What is Tresalia Capital?
Tresalia Capital is the family investment office Aramburuzabala founded in 1996 with her mother and sister. The name comes from “Tres Aliadas,” three allies. It invests the Grupo Modelo fortune across media, real estate, data centers, and consumer brands, and it is now planning its own succession to the next generation.
What happened to Grupo Modelo?
AB InBev bought the remaining 50 percent of Grupo Modelo in June 2013 for about $20 billion, completing its ownership of the Corona brewer. The Aramburuzabala family pocketed at least $3 billion through Grupo Modelo stake sales, according to Bloomberg, and Aramburuzabala used part of the proceeds to buy AB InBev shares and join its board.
Did Maria Asuncion Aramburuzabala sell Corona?
In effect, yes, as part of the family. The 2013 AB InBev deal transferred the remaining half of Grupo Modelo, Corona’s brewer, to AB InBev. The family kept wealth from the sale, not control of the brewery, and Aramburuzabala later stepped off AB InBev’s board in 2023.

Yes, Forbes’ 2026 list puts her at $9.3 billion, the only Mexican woman on the list, with the fortune labeled as hers and her family’s.
Is the wealth gap between Warden and Aramburuzabala narrowing?
No, on current filings it is roughly 65 to 100 times, and it stretches further against stale tracker figures for Warden.
Final Thoughts
If you came here expecting a partnership, a rivalry, or a secret deal, the honest answer is emptier and more useful than that: two women at the top of business in the Americas, on the same leadership list in 2023, with nothing else in common. But the comparison still teaches something worth keeping, because the gap between them is the whole story of how wealth works in 2026. One fortune was earned inside a company, one vesting cycle at a time, and it stops growing the day the job ends. The other fortune was inherited in a crisis, defended in a boardroom, sold at the right moment, and diversified for thirty years, and it keeps growing whether its owner works another day or not.
That distinction is the filter to use the next time a net worth headline flashes a single confident number at you. Ask where the money came from. If it came from a job, expect tens or hundreds of millions and a paper trail of proxies and filings. If it came from a family company sold at the right time, expect billions and a family office quietly planning the next succession. Either way, the number is an estimate, and the honest pages are the ones that say so, the way this one just did.
