When a government contractor can't protect tax returns, don't be surprised when the government stops contracting with them. That's essentially what happened Monday when Treasury Secretary Scott Bessent announced his department was cutting ties with Booz Allen Hamilton Holding Corp. (BAH), the management consulting firm that employed someone who leaked Donald Trump's tax returns to the media.

The Breach That Kept On Giving
The Treasury Department pulled the plug on all 31 separate contracts with Booz Allen, representing $4.8 million in annual spending and $21 million in total obligations. The reason? A spectacular failure to safeguard sensitive taxpayer information that resulted in one of the more brazen IRS data breaches in recent memory.
Between 2018 and 2020, Charles Littlejohn, a Booz Allen employee working on IRS contracts, systematically stole and leaked confidential tax returns belonging to hundreds of thousands of taxpayers. The IRS determined that approximately 406,000 taxpayers had their information compromised. Littlejohn eventually pleaded guilty to felony charges for disclosing confidential tax information without authorization and received a five-year prison sentence.
Among those affected were President Donald Trump and several other wealthy individuals, whose tax returns made their way to media outlets. It's the kind of breach that doesn't exactly inspire confidence in a firm's data security protocols.
Bessent positioned the decision as part of a larger Trump administration effort to clean house among government contractors. "President Trump has entrusted his cabinet to root out waste, fraud, and abuse," he said, calling the cancellation "an essential step to increasing Americans' trust in government."
The Treasury chief argued that Booz Allen "failed to implement adequate safeguards to protect sensitive data," including "the confidential taxpayer information it had access to through its contracts with the Internal Revenue Service." Hard to argue with that assessment when a former employee walked off with 406,000 tax returns.
Market Punishment Doesn't Always Match the Crime
Here's the interesting part: Treasury contracts account for just a tiny sliver of Booz Allen's business. The firm reported $12 billion in fiscal year 2025 revenue and maintains $38 billion in order backlogs. Losing $21 million in total obligations shouldn't move the needle much.
Yet Booz Allen's stock plunged 8.12% on Monday, closing at $93.93. Markets sometimes react to the headline risk and reputational damage rather than the immediate financial impact. When your firm becomes synonymous with "leaked the president's tax returns," other government agencies might start reconsidering their relationship with you too.
The stock already had some technical headwinds, with weak scores on momentum, value, and quality metrics, though it showed favorable price trends in the short and medium terms before Monday's selloff.
