Costco's Q1 FY2025 Filing: The Membership Model Powers On

Costco's quarterly SEC filing for Q1 FY2025 (ended November 24, 2024) reveals a retail operation firing on all cylinders. While competitors struggle with traffic and margin pressure, Costco's unique membership-based model continues delivering consistent growth.

Quarterly Financial Highlights

The 10-Q and the December 12 earnings release present strong headline numbers:

Net Sales: $60.99 billion (up 7.5% year-over-year)
Membership Fees: $1.17 billion (up 7.8%)
Operating Income: $2.20 billion (3.5% of total revenue)
Net Income: $1.80 billion
Comparable Sales: +5.2% (US and Total Company)

The membership fee line deserves special attention. No merchandise cost sits against membership fees, so that revenue flows almost entirely to the bottom line, and it grew faster than net sales (7.8% against 7.5%).

Understanding Costco's Business Model

Costco operates differently from traditional retailers. The membership model creates unique economics:

Membership Revenue

138.8 million cardholders worldwide, 77.4 million of them paid members
Renewal rates: 92.8% (US/Canada), 90.4% (worldwide)
Fee increase ($5 for Gold Star, $10 for Executive) effective September 1, 2024, in the U.S. and Canada
Revenue recognized ratably over 12-month membership period

Merchandise Strategy

Gross margin of just 11.28% of net sales in the quarter
Low prices drive traffic; membership fees generate profit
Limited selection: fewer than 4,000 active SKUs per warehouse, well below other broadline retailers, per the fiscal 2024 10-K

This model creates a virtuous cycle: low prices drive membership, membership fees fund operations, consistent experience drives renewals.

Comparable Sales Breakdown

The earnings release breaks out comparable sales by region and for e-commerce, both as reported and excluding gasoline and foreign exchange:

United States

Comparable sales: +5.2% (+7.2% excluding gasoline and FX)

Canada

Comparable sales: +5.8% (+6.7% excluding gasoline and FX)

Other International

Comparable sales: +4.7% (+7.1% excluding gasoline and FX)

E-commerce

Comparable sales: +13.0% (+13.2% excluding gasoline and FX)

The 10-Q credits the comparable sales gain to increased shopping frequency and a slightly higher average ticket. While many retailers see declining visits offset by higher average tickets (inflation-driven), Costco is growing both metrics. More members are shopping more frequently.

Category Performance

Net sales by merchandise category, from Note 9 of the 10-Q:

Foods and Sundries: $25.1 billion (41% of net sales)
Non-Foods: $16.2 billion (27%)
Fresh Foods: $8.2 billion (13%)
Warehouse Ancillary and Other Businesses: $11.5 billion (19%)

Ancillary and other sales slipped by less than 1%, per the 10-Q, while core merchandise categories grew 10%. Gasoline did the damage: a 12% drop in the average price per gallon cut net sales by $908 million, even though Costco sold about 1% more gallons. Management still calls gas a traffic driver.

Membership Fee Economics

The membership fee increase took effect September 1, 2024, in the U.S. and Canada, and it barely shows yet. Fees are recognized ratably over the year, so the 10-Q calls the first-quarter impact immaterial:

Gold Star: $65 annually (was $60)
Executive: $130 annually (was $120)
Executive members were ~46% of paid members but drove ~73% of worldwide net sales in fiscal 2024, per the 10-K

Per the 10-K, management expects the fee changes to add approximately $370 million of revenue over two years, $190 million of it in fiscal 2025 and mostly in the back half. Renewal rates above 90% point to pricing power, though the 10-Q's trailing calculation covers renewals seven to eighteen months back, before anyone paid the new fee.

Expansion and Capital Investment

Costco's growth strategy focuses on new warehouse openings:

Warehouses opened Q1: 7 new locations, including one relocation
Total warehouses: 897 worldwide as of the December 12 earnings release (617 in the U.S. and Puerto Rico, 280 elsewhere)
Pipeline: 22 more openings planned for the rest of fiscal 2025, including two relocations
Capital expenditure plan: approximately $5.0 billion for fiscal 2025, with $1.26 billion spent in Q1

Per the 10-Q, comparable sales and the 26 net new warehouses opened since the end of Q1 FY2024 drove the $4.27 billion net sales gain. The same filing warns that new warehouses start out less profitable than established ones, and that openings in markets Costco already serves cannibalize sales at its existing warehouses.

Margin Analysis

Costco's intentionally low margins distinguish it from competitors:

Gross Margin: 11.28% of net sales (up 24 basis points; up 7 excluding gasoline price deflation)
SG&A Ratio: 9.59% of net sales (up 14 basis points; flat excluding gasoline price deflation)
Operating Margin: 3.53% of total revenue

That thin merchandise margin is the strategy. By taking minimal margin on merchandise and relying on membership fees for profit, Costco creates a value proposition competitors struggle to match.

The filing notes the July 2024 wage increase weighed on SG&A, and management says it pays much of its workforce better than the industry average. It ties that pay to lower employee turnover and higher productivity.

E-Commerce Growth

E-commerce comparable sales rose 13.0% (13.2% excluding gasoline and FX), per the earnings release, and e-commerce was about 7% of net sales in fiscal 2024, per the 10-K. The 10-K and 10-Q also track a wider digital footprint:

Digitally originated sales: about 9% of fiscal 2024 net sales, counting e-commerce and business delivery along with travel and same-day grocery
Online assortment: 9,000 to 10,000 SKUs, more than double the in-warehouse count
Online membership sales: the 10-Q flags that these typically renew at a lower rate

Costco's e-commerce approach is pragmatic: enhance the membership value rather than chase pure-play competitors on convenience.

Balance Sheet Strength

The filing confirms Costco's fortress balance sheet:

Cash and equivalents: $10.9 billion
Merchandise inventories: $21.0 billion
Total long-term debt: $5.9 billion (including current portion)
Total equity: $24.5 billion

With debt-to-equity of 0.24x and substantial cash, Costco has flexibility for expansion, special dividends, and opportunistic investments.

Visualizing Costco's Profit Flow

A Sankey diagram of Costco's income statement reveals the unique business model visually. Sankify's chart merges Net Sales and Membership Fees into Total Revenue. Then the squeeze starts. Merchandise Costs take most of the total, leaving a narrow Gross Margin band that pays for SG&A before Operating Income passes through interest and tax on its way to Net Income.

Hover over the Membership Fees ribbon, then the Operating Income node, and you see why renewal rates matter so much. Per the 10-Q, $1.17 billion of fees equal 53% of the quarter's $2.20 billion operating income.

Investment Implications

Costco's Q1 filing reinforces the investment thesis:

Strengths

Traffic growth demonstrates value proposition resonance
Fee increase revenue still to come, mostly in the back half of fiscal 2025
International expansion providing growth runway
Balance sheet supports continued investment

Risks to Monitor

Wage inflation pressure on SG&A
Consumer discretionary spending sensitivity
E-commerce competitive dynamics
Warehouse real estate availability

For long-term investors, Costco's SEC filings consistently demonstrate the durability of the membership model. In a retail environment full of disruption, Costco's value proposition and operational execution stand out. The quarterly 10-Q confirms the model continues working as designed.
