Costco Wholesale Corp. (NASDAQ:COST)

The financial data indicates a period of sustained and accelerating expansion in the company's physical asset base from 2021 through 2026. Total gross property and equipment increased consistently, growing from 37,658 million US$ in 2021 to 56,612 million US$ by 2026, representing a total increase of approximately 50.3% over the analyzed period.

Fixed Asset Composition and Trends

Buildings and improvements constitute the largest portion of the asset base, rising from 19,139 million US$ in 2021 to 27,775 million US$ in 2026. Land holdings followed a similar upward trajectory, increasing from 7,507 million US$ to 11,265 million US$, suggesting a strategic focus on securing new sites for expansion. Equipment and fixtures also experienced steady growth, starting at 9,505 million US$ and reaching 14,850 million US$ by the end of the period.

Capital Investment Pipeline

Construction in progress remained relatively stable between 2021 and 2024, fluctuating between 1,266 million US$ and 1,582 million US$. However, a significant upward shift occurred in the final two years, with values rising to 1,882 million US$ in 2025 and peaking at 2,722 million US$ in 2026. This trend suggests a substantial ramp-up in new facility development or major renovations toward the end of the period.

Depreciation and Net Asset Valuation

Accumulated depreciation and amortization grew from 14,166 million US$ in 2021 to 20,979 million US$ in 2026. Despite this increase, the ratio of accumulated depreciation to gross property and equipment remained stable at approximately 37%, indicating a consistent asset replacement cycle and a balanced relationship between new acquisitions and asset aging.

Net Book Value Growth

The net book value of property and equipment demonstrated a strong positive trend, increasing from 23,492 million US$ in 2021 to 35,633 million US$ in 2026. This growth in net assets confirms that capital expenditures consistently outpaced depreciation expenses throughout the six-year window, resulting in a significant increase in the company's total invested capital in tangible assets.

The average age ratio exhibits a period of moderate growth followed by a sustained downward trajectory over the analyzed six-year period. The ratio initially climbed from 46.98% in August 2021 to a peak of 47.97% in September 2023, before entering a consistent decline that resulted in a value of 46.26% by August 2026.

Asset Aging Phase (2021-2023)

An upward trend is observed during the first three years, where the ratio increased by 99 basis points. This movement indicates that accumulated depreciation grew at a slightly faster rate than the acquisition of new gross fixed assets, suggesting a period of asset aging.

Asset Renewal Phase (2023-2026)

Following the 2023 peak, a steady decrease in the ratio is evident. The decline to 46.26% by August 2026 suggests an acceleration in capital expenditures and the integration of newer property, plant, and equipment into the balance sheet, thereby lowering the average age of the asset base.

Stability and Volatility

The overall variance remains constrained within a narrow range of approximately 1.71 percentage points. This stability indicates a disciplined and consistent capital replacement cycle, avoiding drastic shifts in the composition of the asset portfolio.

A consistent expansion of the physical asset base is evident, characterized by steady growth in both gross property and equipment and total land holdings over the analyzed period. Gross property and equipment increased from 37,658 million US dollars in 2021 to a projected 56,612 million US dollars by 2026. This upward trajectory is mirrored in land acquisitions, which rose from 7,507 million US dollars to 11,265 million US dollars in the same timeframe, signaling a sustained commitment to footprint expansion.

Accumulated Depreciation and Asset Aging

Accumulated depreciation and amortization show a continuous linear increase, rising from 14,166 million US dollars in 2021 to 20,979 million US dollars by 2026. This growth is consistent with the natural aging of the asset portfolio and the systematic allocation of costs over the useful lives of the equipment and buildings.

Average Age Ratio Trends

The average age ratio remained relatively stable between 2021 and 2023, peaking at 47.97% in September 2023. Following this peak, a gradual downward trend is observed, with the ratio decreasing to 47.78% in 2024 and further declining to a projected 46.26% by August 2026.

Investment Velocity and Asset Modernization

The decline in the average age ratio starting in 2024 indicates that the pace of new capital expenditures is outpacing the rate of depreciation. This suggests a period of intensified asset modernization or rapid expansion, where the addition of new, non-depreciated assets is reducing the overall weighted average age of the depreciable asset base.

Overall, the data reflects a strategic balance between maintaining existing infrastructure and aggressive investment in new capacity. The shift from a rising to a falling average age ratio suggests a transition toward a younger asset profile, which may potentially reduce future maintenance requirements and improve operational efficiency.
