Sen. Markwayne Mullin sold between $50,000 and $100,000 worth of AZO — AutoZone Inc. — on Feb. 25, 2026, according to a recent congressional disclosure.
The transaction, valued at roughly $75,000 based on the midpoint of the reported range, came as shares of the Memphis-based auto parts retailer traded above $3,500. AutoZone closed recently at $3,562.85, giving the company a market capitalization of about $59.0 billion. Over the past 52 weeks, the stock has ranged from $3,210.72 to $4,388.11.

The filing lists the asset owner as “JT,” an abbreviation commonly used on congressional disclosures to denote a joint account. Lawmakers are required under the STOCK Act to report stock trades within 45 days.
Mullin, an Oklahoma Republican, has been an active market participant during his time in Congress. He has disclosed 468 trades over his career, spanning sectors from health care to industrials. The AutoZone sale represents one of his more sizable individual stock transactions this year based on reported dollar range.
AutoZone has been a standout performer in the retail sector, benefiting from steady demand for replacement auto parts and a resilient consumer repair market. The company’s shares have climbed sharply over the past several years, driven by consistent earnings growth and aggressive share repurchases. Even so, the stock remains below its 52-week high of $4,388.11.
While Mullin does not sit on a committee with direct oversight of the auto parts retail industry, he serves on the Senate Committee on Appropriations and the Senate Committee on Armed Services, among others — panels that can influence broad economic and regulatory policy affecting U.S. businesses.
AutoZone is not an uncommon holding among members of Congress. At least 25 lawmakers have reported trading the stock in recent years, placing it among a group of widely held large-cap consumer names on Capitol Hill. Investors and watchdog groups frequently track such activity through publicly available filings and databases of latest congressional trades.
The February sale came during a period of relative stability for the broader market, with retail and consumer discretionary names showing mixed performance amid shifting interest rate expectations. AutoZone’s premium share price — among the highest nominal prices on the New York Stock Exchange — can amplify the dollar value of even modest position adjustments.
Mullin has not publicly commented on the rationale behind the transaction. Congressional disclosure forms do not require lawmakers to specify whether a trade reflects profit-taking, portfolio rebalancing, or another financial decision.
With nearly 470 trades reported over his congressional career, Mullin remains one of the more active traders in the Senate — and his transactions continue to draw scrutiny from transparency advocates monitoring lawmakers’ exposure to individual equities.
