Live News

Dated April 21, 2026, 14:55 UTC: On Tuesday, President Donald Trump stated in a live CNBC interview that he would “remember” companies that decline to seek refunds for unlawfully imposed IEEPA tariffs, one day after U.S. Customs and Border Protection (CBP) launched an official online portal for importers to file refund claims totaling an estimated $160 billion in eligible repayments, set to be the largest government disbursement of its kind in U.S. history.

Key Highlights

Our analysis identifies four core takeaways for COST investors: First, eligible refund value for COST is material: Wedbush Securities estimates the retailer paid approximately $387 million in IEEPA tariffs between 2025 and early 2026, meaning a full refund would add 80 basis points to 2026 consensus operating margin estimates if claimed without repercussions.

Expert Insights

Sarah Chen, Head of U.S. Hardlines Retail Research at Goldman Sachs, notes the unique dilemma facing COST’s executive team: “For Costco, this is a classic risk-reward calculation. The one-time $387 million refund is a tangible, near-term upside for shareholders, but the long-term cost of alienating the Trump administration could be far higher. COST sources roughly 32% of its high-margin private-label inventory from overseas markets, so targeted tariff hikes on core SKUs including food, apparel and household goods could erase the one-time refund benefit in as little as two quarters, and pressure annual operating margins by 120 to 150 basis points over the next three years. We see management leaning toward delaying any refund filing until further regulatory guidance is released, to avoid unnecessary policy risk.” Michael Torres, Chief Trade Policy Strategist at Morgan Stanley, adds that Trump’s comments are part of a broader strategy to reduce federal outlays ahead of the 2026 midterm elections: “The administration is actively trying to cut down the $160 billion total refund price tag to avoid expanding the fiscal deficit, which has become a key campaign issue for Republican congressional candidates. Companies that decline to file refunds will almost certainly be prioritized for the upcoming ‘trusted importer’ program, which will offer 20-30% preferential tariff rates for firms that align with White House trade policy priorities. For COST, which relies on low import costs to support its industry-leading 14% gross margin model and low price positioning, access to those preferential rates is worth 5 to 7 times the value of the one-time refund, based on our 3-year cash flow projections.” Our proprietary risk model assigns a 65% probability that COST will hold off on filing a refund claim for at least 90 days, and we view the 1.2% after-hours pullback in COST shares as overdone, as the market has not priced in the long-term benefits of preferential tariff access if the firm aligns with White House guidance. We maintain our Buy rating on COST with a 12-month price target of $875 per share, citing resilient 7% annual membership growth, sticky demand for its private-label Kirkland Signature offerings, and efficient global supply chain operations that mitigate a portion of ongoing tariff cost pressure.
