Maximus: How a Welfare-Reform Contractor Became a Publi...

This is one profile in a set on cleared and government contractors and how their founders turn a company into a fortune. The other profiles here end in a sale or a roll into a private equity platform. This one does not. Maximus was founded fifty years ago, went public almost thirty years ago, and has never been taken private, rolled up, or sold. It is the third path this series has found, the founder who kept the company, took it public, and let it compound in plain sight on the open market. It is also the most morally complicated of the three, because the thing it compounds on is the operation of the American safety net.

The twelve-thousand-dollar home business

Maximus began in 1975 at a kitchen-table scale. David V. Mastran, a former federal official who had worked on welfare and health programs inside the government, could not find a private company that understood those programs well enough to make them run efficiently, so he quit and started one, beginning with 12,000 dollars and working alone out of his home. The business he built did an unglamorous thing that turned out to be enormous: it helped state and local governments actually administer welfare and Medicaid, the enrollment, the eligibility checks, the paperwork of the safety net.

The company caught the wave of the 1990s welfare-reform push, and in 1997 Mastran took it public on the New York Stock Exchange under the ticker MMS. The initial offering priced at 16 dollars a share and raised about 84 million dollars, and it netted the founder personally almost 25 million dollars, with other executives sharing another 20 million. That is the first lesson of this series, visible at the very start of the company's public life. Mastran did not draw a salary until the business was worth something and then collect a paycheck. He built an asset and sold a slice of it to the public, and the slice he kept kept compounding.

Growth by acquisition, and the turn toward Washington

For its first few decades Maximus was mostly a state-and-local company, running Medicaid and welfare programs for individual states. What turned it into a federal heavyweight was a burst of acquisitions in the space of a few years, each one buying a deeper position inside Washington.

It bought Acentia, a federal civilian and health technology firm, for 300 million dollars in cash in 2015. Three years later it made the move that reshaped it, buying the United States Federal Citizen Engagement Centers business from General Dynamics for 400 million dollars. That deal mattered because it made Maximus the prime contractor, rather than a subcontractor, on the call centers behind 1-800-MEDICARE and the Affordable Care Act marketplace, two of the highest-volume phone lines in the federal government. Then, in 2021, it acquired three things at once: the federal division of a firm called Attain for 430 million dollars, the disability-exam company Veterans Evaluation Services for 1.4 billion dollars, its largest deal ever, and the servicing of millions of federal student loans handed off from Navient, which it now runs under the brand Aidvantage. In about six years the company had rebuilt itself around the federal government.

The front door to the safety net

Line up what Maximus does today and a single description covers almost all of it: it is the government's outsourced front door to the safety net. When a person calls Medicare, applies for Medicaid, gets a disability exam for the Veterans Affairs department, or dials the number for their federal student loan, there is a good chance the person or system answering works for Maximus.

The anchor is a single contract. In 2022 Maximus won the CMS Contact Center Operations award, worth about 6.6 billion dollars over as long as ten years, which runs both the Medicare and the marketplace lines and handles at least 35 million inquiries a year. On the state side it calls itself the largest provider of health enrollment services in the country, and management has pointed to a roughly 60 percent share of the market for administering Medicaid eligibility and enrollment. The whole business now runs to 5.43 billion dollars in revenue for fiscal 2025 across about 37,200 employees, split into three segments, with United States federal work the largest at roughly 56 percent, state and local services next at about 32 percent, and the shrinking international business the rest.

That concentration is the risk hiding inside the growth story. The company's own annual report notes that roughly 55 percent of revenue comes from the federal government and about one fifth from a single federal agency, with 60 percent riding on its ten largest contracts. A company that started life spread across fifty statehouses is now bound tightly to Washington and, in particular, to the health agencies.

The public compounder

Here is the part that earns Maximus its place in a series about building wealth, and the way it differs from its neighbors. The founders in Built to Be Bought get rich by selling to a private equity firm and rolling their equity into the next platform, where the payoff is carried interest and a second sale. Maximus never did that. It has no private equity sponsor, it pays no carry, and despite fifty years and a five-billion-dollar revenue base, it has never been taken private or forced into a fight with an activist investor. Its wealth is the plain public-market kind. The stock has split more than once, the company has paid a dividend since 2005 and returned hundreds of millions of dollars through buybacks in fiscal 2025 alone, and it pays its executives substantially in shares. A founder started with 12,000 dollars, sold the public a piece at 16 dollars a share, and let the rest ride for a working lifetime. That is a slower and less glamorous machine than the private equity roll, but it is the same underlying idea, ownership of an asset that compounds, run in daylight instead of inside a fund.

The lightning rod

Because Maximus makes its money operating the safety net, it draws fire that a quiet engineering shop never would, and an honest profile has to sit with that. The important discipline here is attribution, because a great deal of the worst press attached to the company actually belongs to its predecessors.

The sharpest ongoing fight is over labor. The Communications Workers of America has been trying since 2017 to unionize the roughly ten thousand people who staff the Medicare and marketplace call centers, a workforce that is overwhelmingly women and heavily women of color, and it has run repeated strikes, the largest in November 2023 with about 700 workers walking out. Starting pay on those lines rose over the decade from around 9 dollars an hour to about 17.75 dollars, with the union pressing for 25. The most inflammatory number in that fight, a claim of 100 million dollars in suppressed wages, is an allegation the union made against General Dynamics, the prior contractor, not against Maximus, and the confirmed government finding was far smaller. Overseas, in the United Kingdom, Maximus took over the government's disability health assessments from Atos in 2015 and expanded into personal-independence-payment assessments in 2023. That system is genuinely troubled, with roughly two-thirds of decisions appealed to a tribunal getting overturned, but the most cited tragedies, including the death that a coroner first linked to a fit-for-work ruling, trace to assessments Atos performed before Maximus ever held the contract. The failure is better understood as systemic to the outsourced-assessment model than as uniquely Maximus's doing. Likewise, the 1.7 billion dollar settlement and lifetime servicing ban that make headlines in student loans belong to Navient, not to the Aidvantage operation Maximus inherited, though Aidvantage drew its own two-million-dollar federal penalty for botched billing statements after the 2023 repayment restart.

There are real marks on the company's own record too. A 2023 breach of the MOVEit file-transfer tool exposed the data of somewhere between 8 and 11 million people and cost tens of millions to remediate. Maximus paid 30.5 million dollars in 2007 over Medicaid billing in the District of Columbia and 8 million dollars in 2025 to settle allegations that it manipulated call-quality scores on the 2020 Census. And in 2025, as Congress passed a law adding Medicaid work requirements, Democratic senators went after Maximus by name as the contractor that stands to profit as millions lose health coverage, quoting the company's own investor pitch that more frequent eligibility checks could actually raise its call volume. That is the uncomfortable core of the business: it can be paid more when the safety net is made harder to navigate.

One expectation worth correcting, because it cuts the other way. Given how federal Maximus has become, you might assume the 2025 government-efficiency cutting hit it hard. It did not. Management put the direct effect at a few million dollars against a five-billion-dollar base, the stock reached an all-time high in January 2026 before falling about 40 percent by that summer on worries about flat revenue rather than budget cuts. Entitlement work, it turns out, is stickier than discretionary contracting.

The ledger reading

Set the three profiles side by side and this series has now found three ways to end up on the ownership side of the line. PeopleTec sold the company to its own employees. Amentum let private equity buy it, bolt on, and float it. Maximus did the oldest and simplest thing of all: a founder built an asset, took it public, and never let go, and it compounded for fifty years through dividends and buybacks and a rising share count of value. The mechanics are the cleanest illustration in the whole series of why owning beats earning, the argument underneath The W-2 Trap.

But Maximus also supplies the sharpest version of the tension that book is named for. The wealth that compounded for the owners was generated, in large part, by the labor of people on 9-to-18-dollar-an-hour phone lines, the workers the union has spent eight years trying to organize. The founder converted his hours into an asset. The people answering the Medicare calls are still selling theirs. That gap, between the person who owns the compounding thing and the person whose wages fund it, is the entire subject of this series, and nowhere is it drawn more plainly than inside the company that runs the safety net.
