Arista Networks Inc. (NYSE:ANET)

Property, plant, and equipment exhibited a general upward trend over the five-year period from 2021 to 2025. This growth was driven primarily by increases in equipment and machinery, and construction-in-process. However, the rate of growth varied significantly across different asset categories and experienced a notable acceleration in the final year of the period.

Land

The value of land increased steadily from US$40.145 million in 2021 to US$47.300 million in 2025, representing a cumulative increase of approximately 17.8%. The growth rate appears relatively consistent year-over-year.

Equipment and Machinery

Equipment and machinery demonstrated the most substantial growth, increasing from US$90.915 million in 2021 to US$188.300 million in 2025. This represents a cumulative increase of over 107%. Growth was particularly strong between 2022 and 2023, and again between 2024 and 2025, suggesting significant investment in this area.

Computer Hardware and Software

Computer hardware and software also increased consistently, rising from US$44.083 million in 2021 to US$66.200 million in 2025, a cumulative increase of approximately 50%. The rate of increase slowed slightly between 2024 and 2025.

Furniture and Fixtures

Furniture and fixtures remained relatively stable, fluctuating slightly between US$3.575 million and US$3.700 million. This suggests limited investment in this asset category during the period.

Leasehold Improvements

Leasehold improvements increased from US$30.502 million in 2021 to US$38.400 million in 2025, representing a cumulative increase of approximately 25.9%. Growth was moderate and consistent throughout the period.

Construction-in-Process

Construction-in-process exhibited the most dramatic change. Starting at US$2.378 million in 2021, it increased significantly to US$107.900 million in 2025. This substantial increase indicates a major ongoing construction project nearing completion, or the initiation of several large projects. The majority of the increase occurred between 2024 and 2025.

Gross Property and Equipment

Gross property and equipment increased substantially, from US$211.657 million in 2021 to US$451.800 million in 2025, a cumulative increase of over 113%. This growth mirrors the increases observed in equipment and machinery and construction-in-process.

Accumulated Depreciation

Accumulated depreciation increased consistently throughout the period, from US$133.023 million in 2021 to US$248.700 million in 2025. This is expected given the increase in the overall asset base. The rate of increase in accumulated depreciation generally tracked the growth in gross property and equipment.

Net Property and Equipment

Net property and equipment increased from US$78.634 million in 2021 to US$203.100 million in 2025. While generally trending upward, net property and equipment decreased slightly between 2023 and 2024, before experiencing a significant increase in 2025, driven by the substantial increase in construction-in-process.

The significant increase in construction-in-process in 2025 warrants further investigation to understand the nature and expected timeline for completion of these projects. The overall trend suggests a period of substantial investment in property, plant, and equipment, which is expected to contribute to future operational capacity.

The analysis of property, plant, and equipment reveals evolving characteristics regarding asset age and useful life estimations. The average age ratio demonstrates fluctuation over the observed period, while estimations of total useful life and remaining life also exhibit changes. These shifts warrant further investigation to understand their implications for future capital expenditure and depreciation expense.

Average Age Ratio

The average age ratio decreased from 77.56% in 2021 to 74.56% in 2022, indicating a relative shift towards newer assets within the asset base. A slight increase to 76.76% occurred in 2023, followed by a more pronounced rise to 80.94% in 2024. However, a significant decrease to 61.48% is observed in 2025. This substantial decline suggests a considerable influx of new assets or a re-evaluation of asset ages during that year.

Estimated Total Useful Life

The estimated total useful life remained constant at 8 years from 2022 through 2024. Prior to this, in 2021, the estimated total useful life was 9 years. A notable increase to 13 years is recorded in 2025. This lengthening of the estimated useful life could reflect improvements in asset durability, changes in usage patterns, or a revised depreciation policy.

Estimated Age and Remaining Life

The estimated age, representing the time elapsed since purchase, remained stable at 6 years from 2022 to 2024, following an initial value of 7 years in 2021. In 2025, the estimated age increased to 8 years. Correspondingly, the estimated remaining life was consistently 2 years from 2021 to 2024, before increasing to 5 years in 2025. The concurrent increase in both estimated age and remaining life in 2025 is directly linked to the extended total useful life estimation.

The interplay between these ratios suggests a potential pattern of asset replacement or revaluation. The increase in estimated useful life in 2025, coupled with the decrease in the average age ratio, indicates a possible modernization of the asset base or a change in how asset lives are determined. Continued monitoring of these trends is recommended to assess the long-term impact on the company’s financial position.

An examination of the presented financial information reveals trends in accumulated depreciation, gross property and equipment, land holdings, and the average age ratio over a five-year period. Accumulated depreciation consistently increased throughout the period, rising from US$133,023 thousand in 2021 to US$248,700 thousand in 2025. Gross property and equipment also exhibited an upward trend, more than doubling from US$211,657 thousand in 2021 to US$451,800 thousand in 2025, with a significant increase between 2024 and 2025. Land holdings experienced moderate growth, increasing from US$40,145 thousand in 2021 to US$47,300 thousand in 2025. The average age ratio fluctuated during the period, initially decreasing slightly before increasing and then decreasing substantially in 2025.

Accumulated Depreciation

Accumulated depreciation demonstrated a consistent year-over-year increase throughout the observed period. This suggests a continuous utilization and consumption of the company’s fixed assets. The rate of increase appeared relatively stable until 2025, where the increase was notably higher than previous years, potentially reflecting increased asset utilization or new asset additions.

Gross Property and Equipment

Gross property and equipment showed a strong upward trajectory, indicating substantial investment in fixed assets. The most significant increase occurred between 2024 and 2025, suggesting a period of considerable capital expenditure. This expansion in gross property and equipment is a key driver of the increasing accumulated depreciation.

Land Holdings

Land holdings experienced a modest, but consistent, increase over the five-year period. The growth rate was significantly lower than that of gross property and equipment, indicating that land acquisition was not a primary focus of capital allocation during this time. The relatively stable land value suggests it is held for long-term strategic purposes.

Average Age Ratio

The average age ratio exhibited volatility. It initially decreased from 77.56% in 2021 to 74.56% in 2022, then increased to 80.94% in 2024. A substantial decrease to 61.48% was observed in 2025. This significant drop in 2025, coinciding with the largest increase in gross property and equipment, suggests a substantial influx of newer assets, effectively lowering the overall average age of the asset base. The ratio’s fluctuations indicate changes in the composition and age distribution of the company’s fixed assets.

Property and equipment, gross, increased steadily from 2021 to 2025, exhibiting significant growth between 2024 and 2025. Land values also increased consistently over the period, though at a slower rate. Depreciation expense demonstrated an increasing trend from 2021 to 2024, followed by a decrease in 2025. A notable shift occurred in the estimated total useful life of the assets during the analyzed timeframe.

Property and Equipment, Gross

The gross value of property and equipment increased from US$211.657 million in 2021 to US$451.800 million in 2025. The largest single-year increase occurred between 2024 and 2025, suggesting substantial investment in assets during that period. This growth could indicate expansion, modernization, or acquisitions.

Land

Land values rose from US$40.145 million in 2021 to US$47.300 million in 2025. The increases were relatively consistent year-over-year, indicating a steady, though modest, investment in land.

Depreciation Expense

Depreciation expense increased from US$19.500 million in 2021 to US$34.000 million in 2024, reflecting the growing asset base. However, a decrease to US$30.900 million was observed in 2025. This decrease, coupled with the significant increase in gross property and equipment, suggests a change in depreciation methods or asset composition.

Estimated Total Useful Life

The estimated total useful life of the assets decreased from 9 years in 2021 to 8 years from 2022 to 2024. This reduction could be due to technological obsolescence, changes in usage patterns, or a revised assessment of asset longevity. A substantial increase to 13 years was then recorded in 2025. This significant change warrants further investigation as it will materially impact future depreciation expense and reported earnings. The increase in estimated useful life in 2025 may be related to the assets acquired in that year, or a company-wide reassessment of asset lives.

The combination of increasing gross property and equipment, fluctuating depreciation expense, and a significant change in estimated useful life in the final year suggests a dynamic asset management strategy and potentially a shift in the company’s investment profile. The increase in useful life in 2025 should be examined in conjunction with the substantial increase in gross property and equipment to understand its full implications.

Accumulated depreciation consistently increased from 2021 to 2025, indicating a continued recognition of the cost of assets over their useful lives. Depreciation expense also exhibited an overall upward trend during the same period, though with some fluctuation. The reported time elapsed since purchase provides context for these depreciation patterns.

Accumulated Depreciation Trend

Accumulated depreciation rose from US$133,023 thousand in 2021 to US$248,700 thousand in 2025. This represents a substantial increase over the five-year period, suggesting a significant portion of the asset base has been depreciated. The rate of increase appears to have slowed slightly between 2024 and 2025.

Depreciation Expense Trend

Depreciation expense increased from US$19,500 thousand in 2021 to US$34,000 thousand in 2024, demonstrating a considerable rise in the annual depreciation charge. However, in 2025, depreciation expense decreased to US$30,900 thousand. This decrease could be due to several factors, including asset disposals, changes in the asset base, or adjustments to estimated useful lives.

Time Elapsed Since Purchase

The reported time elapsed since purchase remained at 6 years from 2022 through 2024. This suggests a concentrated period of asset acquisition around 2018-2019. In 2025, the time elapsed increased to 8 years, potentially indicating a more recent wave of asset purchases or the aging of the existing asset base. The consistency for three years followed by an increase warrants further investigation into capital expenditure patterns.

The relationship between accumulated depreciation and depreciation expense is as expected; as assets age, the annual depreciation expense generally increases until a significant portion of the asset's cost has been allocated. The decrease in depreciation expense in 2025, coupled with the increase in time elapsed since purchase, suggests a potential shift in the company’s asset profile or depreciation methods.

Property and equipment, net, increased from 2021 to 2023, experienced a slight decrease in 2024, and then a substantial increase in 2025. Land values have consistently increased over the five-year period. Depreciation expense has generally trended upward, with a slight decrease observed in the most recent year. A significant change is noted in the estimated remaining life of the property, plant, and equipment.

Property and Equipment, Net

The net value of property and equipment increased from $78.634 million in 2021 to $101.580 million in 2023, representing a compound annual growth rate of approximately 14.8%. A minor decrease to $98.845 million was observed in 2024, followed by a considerable increase to $203.100 million in 2025. This substantial increase in 2025 warrants further investigation to determine the underlying cause, such as significant acquisitions or capital expenditures.

Land

Land values have shown consistent growth, increasing from $40.145 million in 2021 to $47.300 million in 2025. The annual increases have been relatively modest, suggesting a steady, rather than rapid, appreciation in land value.

Depreciation Expense

Depreciation expense has generally increased over the period, rising from $19.500 million in 2021 to $34.000 million in 2024. However, a decrease to $30.900 million was recorded in 2025. This decrease could be attributable to a change in the asset base, a revision of depreciation methods, or the impact of the extended estimated remaining life.

Estimated Remaining Life

The estimated remaining life of the property, plant, and equipment remained constant at 2 years from 2021 to 2024. A notable increase to 5 years is observed in 2025. This extension of the estimated useful life will have a significant impact on future depreciation expense, reducing the annual charge and increasing the net book value of the assets. The reason for this change should be examined, as it could reflect improvements to the assets, a reassessment of their useful life, or a change in accounting policy.

The combination of the increased net property and equipment value in 2025 and the extended estimated remaining life suggests a potentially significant impact on future financial performance and reported asset values. Further investigation into the specific events driving these changes is recommended.
