In a filing disclosed on January 16th, Senator Markwayne Mullin (R-Oklahoma) reported purchasing between $15,001 and $50,000 of Costco Wholesale shares on December 29th. This transaction adds to his portfolio activity on that date, which included similar-sized purchases in major names such as Deere & Company, Hilton Worldwide, RTX, Coca-Cola and Elevance Health. Mullin’s entry into Costco stock underscores growing confidence among policymakers in the retailer’s membership-driven business model and long-term growth prospects.

Costco’s quarter ended December 3rd delivered earnings per share of $4.34, outperforming the consensus by $0.07, while revenue reached $67.31 billion—an 8.3% year-over-year increase and $0.28 billion above estimates. Net margin stood at 2.96% and return on equity at 29.35%. The board declared a quarterly dividend of $1.30 per share (a 5.20 annualized payout), reflecting a payout ratio of 27.85%, with record holders as of January 30th to receive the payment on February 13th.

Costco reported 81.4 million membership accounts at quarter end, up 5.2% year-over-year, driven by strong renewal rates and international warehouse openings. Analysts cite resilient same-store sales—7.0% growth in December following 5.9% and 5.3% gains in fiscal years 2025 and 2024—and improving momentum indicators as catalysts for further upside. However, the shares trade at a premium P/E multiple near 52x, placing sensitivity on any deceleration in sales or margin expansion, even as consensus forecasts call for mid-single-digit revenue growth and low-double-digit EPS gains in fiscal 2026.
