The membership model is the paramount driver of profitability, enabling Costco to offer industry-leading prices on goods and services, which in turn drives member loyalty and growth.
Aggressive investment in digital channels—from the mobile app and e-commerce to same-day delivery partnerships—is critical for long-term growth, even if it introduces challenges like lower initial renewal rates for online sign-ups.
The Kirkland Signature private label is a key strategic asset that provides a 15-20% value proposition over national brands, drives sales growth faster than the company average, and helps mitigate tariff impacts.
A steady, calculated pace of global warehouse expansion (28-30+ new units per year) is essential, requiring creative real estate solutions to penetrate dense, high-value urban markets.
Maintaining price leadership is non-negotiable; this involves passing savings from lower commodity costs and reduced tariffs directly to members to reinforce trust and value.
Q1 2026
Millerchip reports strong Q1 results with 8.2% net sales growth and 20.5% e-commerce growth. He forecasts a $6.5 billion CapEx for the fiscal year and anticipates a 'potential slight decline' in renewal rates due to a mix shift towards online sign-ups.
February 2026
During the Q2 call, Millerchip details February's performance, noting a 7.9% increase in total company comparable sales. He specifies that performance was affected by both a positive 0.5% impact from the Lunar New Year and store closures due to severe weather in the U.S. Northeast.
Q2 2026
Reports accelerated growth with 9.1% net sales growth and 22.6% digital sales growth. He confirms the previously anticipated renewal rate dip, with the U.S. and Canada rate falling 10 basis points, which he attributes to the online member trend. He reiterates the $6.5 billion CapEx forecast.
Fiscal Year 2026 Outlook
Across both earnings calls, Millerchip maintains a consistent outlook for FY2026, including a $6.5 billion capital expenditure plan and the opening of 28 net new warehouses.
Future Outlook (post-Q2 2026)
Millerchip outlines a long-term strategy that includes accelerating new warehouse openings to over 30 per year, developing a retail media business, and working with AI companies to enhance product visibility in next-generation shopping tools.
▶Digital Acceleration and E-commerce Integration
Millerchip consistently highlights the rapid growth of Costco's digital channels, with e-commerce sales, website traffic, and app usage all increasing significantly. He emphasizes that digitally-enabled sales are outpacing warehouse growth and that new initiatives like personalized recommendation carousels are already driving hundreds of millions in sales.
Costco is successfully translating its warehouse value proposition to the digital realm, but this strategic shift introduces new challenges, such as managing the lower renewal rates associated with younger, digitally-acquired members.
▶Membership as the Core Economic EngineApr 2026
The foundation of Millerchip's financial reporting is the strength of the membership model. He details consistent quarter-over-quarter growth in total paid members, executive memberships, and high-margin membership fee income, which increased by over 13% in both Q1 and Q2.
The predictable, high-margin revenue from membership fees provides Costco with a significant competitive advantage, allowing it to absorb commodity price fluctuations and offer aggressively low prices on goods, reinforcing member loyalty.
▶Strategic Expansion and Operational Innovation
Millerchip outlines a clear plan for physical growth, targeting 28 new warehouses in FY2026 and over 30 annually in subsequent years. He also discusses innovative approaches to expansion, such as using creative real estate models with parking decks and residences in dense urban markets like Los Angeles.
Despite its massive scale, Costco is not resting on its laurels and is actively pursuing both geographic expansion and in-store technological efficiencies, like automated pay stations, to drive future growth and improve the member experience.
▶Proactive Management of Macroeconomic HeadwindsApr 2026
Millerchip provides transparent commentary on external economic factors, including the impact of gas price deflation, foreign exchange rates, and commodity costs on sales and margins. He also details Costco's mitigation strategies for tariffs, such as shifting production and focusing on the Kirkland Signature brand, and acknowledges geopolitical risks in the Middle East.
Millerchip's detailed discussion of macroeconomic factors demonstrates a sophisticated approach to risk management that aims to protect the company's value proposition for members while navigating a complex global environment.
