The Oklahoma Republican disclosed the transaction in a periodic filing required under the STOCK Act, which mandates lawmakers report stock trades within 45 days. Based on the disclosure range, the value of the sale is estimated at roughly $75,000.

AutoZone is one of the largest U.S. retailers of aftermarket automotive parts and accessories, serving both do‑it‑yourself consumers and professional repair shops through thousands of locations. The Memphis‑based company has built a reputation among investors for steady same‑store sales growth and an aggressive share repurchase strategy that has helped drive its stock price into the thousands per share.
Shares recently traded around $3,562, giving the company a market capitalization near $59 billion. The retailer benefits from long‑term trends tied to the aging U.S. vehicle fleet: when consumers keep cars longer, demand for replacement parts and maintenance products typically rises.
A popular name among lawmakers
Mullin is not alone on Capitol Hill in trading the stock. Disclosure data show at least 23 members of Congress have reported transactions involving AutoZone at various points, underscoring the company’s visibility among investors tracking consumer spending and automotive repair demand.
AutoZone’s business model is closely linked to everyday economic conditions. When new vehicle prices rise or interest rates make car financing more expensive, many consumers opt to repair existing vehicles rather than replace them—supporting sales for retailers like AutoZone.
The company has also expanded its commercial delivery network for professional repair shops, a segment that has become an increasingly important growth driver. Analysts frequently monitor the firm’s same‑store sales, operating margins, and buyback pace as signals of operational efficiency.
Mullin’s role on Capitol Hill
Mullin serves on several influential Senate committees, including the Senate Committee on Appropriations, the Senate Armed Services Committee, the Senate Committee on Health, Education, Labor, and Pensions, and the Senate Committee on Indian Affairs. The Appropriations panels he sits on oversee major federal spending areas ranging from defense to health and education programs.
While those assignments do not directly oversee the auto‑parts retail industry, they place Mullin at the center of debates over federal spending, labor policy, and broader economic conditions that can shape consumer behavior.
The Feb. 25 AutoZone transaction is one of 73 trades Mullin has reported during his congressional career. Congressional trading activity across both chambers continues to draw scrutiny from watchdog groups and voters, with lawmakers’ financial disclosures frequently tracked through databases of the latest congressional trades.
For investors, AutoZone remains a closely watched retail bellwether tied to the durability of consumer repair spending—and the willingness of Americans to keep older cars on the road.
