Card Y1-A: The Renewal Cohort That Shouldn't Be Slipping#
The latest internal membership-quality report, circulated to Vachris and Millerchip only last week, flags an early signal that has not yet shown up in the headline 92.3% renewal rate. Among Executive members who joined in the 2021–2022 surge cohort — the pandemic-era sign-ups now hitting their fourth renewal — the auto-renew opt-out rate is running approximately 180 basis points above prior cohorts at the equivalent tenure. The drop is concentrated in two demographics: members under 35 in dense urban markets (where the warehouse is a 30+ minute drive) and members in households with GLP-1 prescriptions (lower trip frequency, smaller basket). The aggregate effect on FY26 renewal is modest — perhaps 30–40 bps headwind — but the trajectory is real. The membership team's preliminary recommendation is a digital-experience investment targeted at this cohort. The merchandising team's preliminary recommendation is to do nothing and let the data mature another two quarters.
What this signals: The membership compact is not as bulletproof as the public number suggests, and the obvious remedies (more app, more digital, more delivery) are exactly the moves that risk eroding the warehouse-trip economics that drive the rest of the renewal base.
Card Y1-B: What Kirkland Could Actually Be#
A Wholesale Industries strategy memo prepared for the board's January offsite — never released externally — models what Kirkland Signature revenue could look like under three scenarios by FY30: base case ($110B, current trajectory), accelerated case ($140B, deeper apparel/electronics/supplements penetration plus selective international SKU expansion), and aggressive case ($170B, including a meaningful private-label push into beauty, OTC health, and pet). The accelerated case requires a step-change in product-development cadence — current Kirkland item launch timelines run 14–22 months from concept to shelf; the memo argues vendor-partnered AI in formulation, packaging design, and consumer testing could compress this to 6–9 months without quality compromise. The capex ask is modest by Costco standards. The cultural ask is larger: it requires buyers to share more decision authority with analytics teams, which two senior merchandising VPs have already pushed back on.
What this signals: The largest unrealized AI lever in the company is private-label velocity, not customer-facing technology — but capturing it requires breaking a buyer-led culture that has been one of Costco's structural advantages.

Card Y2-A: The Vendor Quiet Quit#
Three of Costco's top-15 branded CPG vendors have, in the last 90 days, materially reduced the depth of their joint-business-planning engagement. They are still present, still shipping, still negotiating annual programs — but the executive-level strategic conversations (new-item roadmaps, exclusive packaging, promotional calendars) have thinned noticeably. Internal hypothesis: these vendors are reallocating senior commercial bandwidth toward retail-media-funded relationships with Walmart, Amazon, and Kroger, where the marketing dollars they spend translate directly into measurable shelf and digital placement. Costco's deliberate non-pursuit of retail media means there is no equivalent currency. One vendor's category lead said it plainly to your SVP of Foods last month: "We love Costco. We just have to spend our time where the scoreboard moves." The merchandising response options on the table range from indifference (the model still works) to a targeted Kirkland substitution program in the categories where engagement has thinned most.
What this signals: The decision not to build a retail media network has a quiet cost that is now starting to show up — and the most natural counter-move (faster Kirkland substitution) accelerates a dynamic that further reduces branded-vendor leverage, with second-order effects on the treasure-hunt assortment.
Card Y2-B: The Activist Letter That Hasn't Been Sent Yet#
Millerchip's office received a courtesy heads-up from a major sell-side analyst that a well-known activist fund has been building a position over the last two quarters and has commissioned a detailed strategic review of Costco's "underutilized" assets. The review reportedly focuses on three areas: (1) a premium membership tier at a $200+ price point with faster e-commerce, exclusive products, and member health services; (2) monetization of first-party member data through a Costco-branded ad network limited to on-property and digital placements; (3) a partial spin or IPO of Costco Logistics. The fund has not filed and has not requested a meeting. The analyst's read is that they will go public within 6–9 months if Costco does not pre-empt with a credible "modernization without rupture" narrative. The board's standing posture on activist pressure has been polite refusal, but two newer directors have privately asked whether the premium-tier idea, specifically, deserves a fresh look.
What this signals: External pressure is building on exactly the adjacencies Costco has historically declined, and the question is no longer whether the pressure exists but whether to absorb it, pre-empt it with a narrow modernization move, or hold the line and accept the activist fight when it comes.
