BUY $1,001 - $15,000 — Costco Wholesale Corporation - Common Stock

⚠️ PRESIDENTIAL ACTION: Presidential Memorandum signed 7/30/2026: "Presidential Determination Pursuant to Section 101 of the Defense Production Act of 1950, as Amended". This DPA action will boost investment and production in domestic critical mineral recycling and processing, likely increasing stock valuations for pure-play recovery companies and defense contractors reliant on secure rare-earth magnet supplies, while potentially raising costs for import-dependent manufacturers.

Congressional Legislation Affecting Costco Wholesale Corporation ($COST)

The Food Date Labeling Act of 2025 (S.2541) standardizes voluntary date labels but carries no appropriations, is in early-stage committee, and imposes only trivial one-time compliance costs on grocery retailers and food distributors. Near-term market impact is negligible. Real market data shows KR down -6.27% and WMT up +5.1% over 30 days, driven by macro factors entirely unrelated to this procedural bill.

Minimal one-time label redesign cost; Kirkland's already standardized packaging approach reduces implementation friction.

S2541

The Reclaim Trade Powers Act (HR2459) has been introduced in the House and referred to the Ways and Means Committee. It would repeal the President's authority to impose temporary tariffs of up to 15% to address balance-of-payments deficits. At this early procedural stage with zero markup or Senate action, there is no direct, measurable market impact.

HR2459

The Stop Price Gouging in Grocery Stores Act of 2026 (S.3892), introduced in the Senate on February 12, 2026, proposes price controls and a ban on surveillance-based pricing for retail food stores. This early-stage bill threatens to compress margins for traditional grocers like Kroger ($KR) and Walmart ($WMT) by capping price increases and restricting data-driven pricing tools, while Costco ($COST) faces minimal disruption due to its existing low-markup model.

Costco operates on a famously low-margin model (max 14% markup on brand, 15% on Kirkland) with membership fees driving profit. The bill's 120% of average price threshold closely aligns with Costco's existing pricing philosophy, making it the least operationally disrupted player.

S3892
