Linde plc (NASDAQ:LIN)

Over the five-year period, a consistent expansion of gross property, plant, and equipment (PP&E) is observed. This growth is primarily driven by increases in production plants, construction in progress, and storage tanks. However, net PP&E exhibits a more moderate growth pattern due to the offsetting effect of accumulated depreciation.

Gross PP&E Growth

Gross PP&E increased steadily from US$48.456 billion in 2021 to US$68.079 billion in 2025, representing a cumulative increase of approximately 40.5%. The most significant growth occurred between 2024 and 2025, with an increase of US$9.36 billion. Production plants consistently represent the largest component of gross PP&E, and their expansion is a key driver of the overall growth.

Individual Asset Category Trends

Production plants demonstrate a consistent upward trend, increasing from US$29.120 billion in 2021 to US$40.301 billion in 2025. Storage tanks also show consistent growth, albeit at a smaller scale, rising from US$4.441 billion to US$6.215 billion. Transportation equipment and other, and cylinders also exhibit growth, but at varying rates. Buildings experienced a slight decrease between 2021 and 2022, followed by a recovery and continued growth, but remain the smallest component. Land and improvements show minimal fluctuation throughout the period.

Construction in Progress

Construction in progress has increased significantly, from US$3.062 billion in 2021 to US$6.130 billion in 2025. This substantial increase suggests ongoing investment in future capacity expansion. The largest increase in construction in progress occurred between 2024 and 2025, indicating accelerated project development during that period.

Accumulated Depreciation

Accumulated depreciation increased consistently throughout the period, from US$22.453 billion in 2021 to US$39.819 billion in 2025. This increase is expected given the growth in gross PP&E. The rate of depreciation increase appears to be accelerating, particularly between 2023 and 2025.

Net PP&E

Net PP&E initially decreased from US$26.003 billion in 2021 to US$23.548 billion in 2022, before stabilizing and increasing to US$28.260 billion in 2025. The initial decline is attributable to the higher rate of depreciation outpacing the growth in gross PP&E. The subsequent increase in net PP&E from 2023 onwards indicates that the growth in gross PP&E is now exceeding the depreciation expense.

In summary, the company is actively investing in its asset base, with a particular focus on production plants and ongoing construction projects. While accumulated depreciation is increasing, the overall trend in net PP&E is positive, suggesting effective capital expenditure management and a growing asset base.

An increasing trend is observed across the examined metrics related to property, plant, and equipment over the five-year period. The average age ratio demonstrates a consistent rise, while the estimated total useful life and elapsed time since purchase also exhibit upward movement. This suggests a general aging of the asset base.

Average Age Ratio

The average age ratio increased from 47.43% in 2021 to 59.53% in 2025. This indicates that, as a percentage of the total asset base, a greater proportion consists of older assets over time. The rate of increase appears to be slowing, with smaller increments observed in the later years of the period.

Estimated Total Useful Life

The estimated total useful life of the assets has increased significantly, moving from 12 years in 2021 to 21 years in 2025. This could be due to several factors, including changes in accounting estimates, the acquisition of assets with inherently longer lifespans, or improvements in asset maintenance extending their usability. The most substantial increases occurred between 2022 and 2023, and again between 2024 and 2025.

Estimated Age and Remaining Life

The estimated age, representing the time elapsed since purchase, rose from 6 years in 2021 to 12 years in 2025. Concurrently, the estimated remaining life increased from 6 years to 8 years. While the age increased by 6 years, the remaining life only increased by 2 years. This suggests that the rate at which assets are being replaced or renewed is not keeping pace with the aging of the existing asset base. The difference between elapsed time and remaining life is widening, potentially indicating a need for increased capital expenditure in the future to maintain operational capacity.

Overall, the observed trends suggest a maturing asset base. Continued monitoring of these ratios, alongside capital expenditure plans, is recommended to assess the long-term sustainability of the asset portfolio and potential impacts on future financial performance.

The value of accumulated depreciation has consistently increased from 2021 to 2025, rising from US$22,453 million to US$39,819 million. Simultaneously, the gross value of property, plant, and equipment has also increased over the same period, moving from US$48,456 million to US$68,079 million. Land and improvements have remained relatively stable, with a slight increase observed from US$1,121 million in 2021 to US$1,188 million in 2025.

Average Age Ratio

The average age ratio exhibits a consistent upward trend from 47.43% in 2021 to 59.53% in 2025. This indicates that, on average, the company’s property, plant, and equipment are becoming older relative to their depreciable lives. The rate of increase slowed between 2023 and 2024 (56.74% to 58.85%) but accelerated again between 2024 and 2025 (58.85% to 59.53%).

The increasing accumulated depreciation alongside the growing gross property, plant, and equipment suggests ongoing investment in new assets, coupled with the continued depreciation of existing ones. The relatively stable value of land and improvements indicates limited activity in that specific asset category. The rising average age ratio warrants attention, as a continually aging asset base may eventually necessitate increased capital expenditure for replacements to maintain operational efficiency and avoid potential disruptions.

The acceleration in the average age ratio in the most recent period (2024-2025) could be a signal to investigate the timing of recent asset acquisitions and the depreciation methods employed. Further analysis should consider the specific composition of the asset base and the potential impact of aging assets on future maintenance costs and productivity.

Over the five-year period, property, plant and equipment, gross experienced consistent growth, increasing from US$48,456 million in 2021 to US$68,079 million in 2025. Land and improvements remained relatively stable, with a slight increase observed from US$1,121 million to US$1,188 million over the same timeframe. Depreciation expense exhibited a decreasing trend from US$3,912 million in 2021 to US$3,246 million in 2025. Notably, the estimated total useful life of the assets has increased significantly, progressing from 12 years in 2021 to 21 years in 2025.

Gross Property, Plant & Equipment

The consistent increase in gross property, plant and equipment suggests ongoing investment in fixed assets. The growth rate appears to have accelerated between 2023 and 2025, with larger absolute increases observed during those years. This could indicate a period of significant expansion or major capital projects.

Depreciation Expense

The decline in depreciation expense, despite the increasing gross value of property, plant and equipment, is a key observation. This decrease is likely attributable to the increasing estimated useful life of the assets. As the useful life extends, the annual depreciation charge is reduced, resulting in lower expense.

Estimated Useful Life

The substantial increase in estimated total useful life from 12 to 21 years is the most prominent trend. This suggests a reassessment of the expected longevity of the asset base. Potential reasons for this change include improvements in asset maintenance, technological advancements extending asset usability, or a change in accounting policies regarding useful life estimations. The lengthening useful life directly impacts the depreciation expense, reducing it over time.

The combination of increasing gross property, plant and equipment and decreasing depreciation expense, driven by the extended estimated useful life, suggests a potential improvement in asset efficiency and a reduction in the rate at which assets are expensed. Further investigation into the reasons behind the change in estimated useful life is recommended to fully understand the implications for financial reporting and asset management.

Analysis reveals a consistent increase in accumulated depreciation over the five-year period, alongside a generally decreasing trend in annual depreciation expense. The reported time elapsed since purchase also demonstrates a steady progression, indicating the aging of the asset base.

Accumulated Depreciation

Accumulated depreciation increased significantly from US$22,453 million in 2021 to US$39,819 million in 2025. This represents a cumulative increase of 77.5% over the period. The rate of increase appears to be accelerating, with larger absolute increases observed in later years, particularly between 2023 and 2025.

Depreciation Expense

Depreciation expense exhibited a downward trend, decreasing from US$3,912 million in 2021 to US$3,246 million in 2025. While fluctuations occurred, the overall direction is clearly decreasing. The decline is not linear, with a smaller decrease observed between 2024 and 2025 compared to prior years. This suggests a potential stabilization of depreciation charges.

Time Elapsed Since Purchase

The reported time elapsed since purchase increased consistently from 6 years in 2021 to 12 years in 2025. This linear progression confirms the ongoing aging of the property, plant, and equipment asset base. The increasing age, coupled with rising accumulated depreciation, suggests a potential need for future capital expenditures to replace or upgrade assets.

The combination of increasing accumulated depreciation and decreasing depreciation expense suggests that a larger proportion of the asset base is becoming fully depreciated. This could indicate a shift in the composition of the asset base, with older, fully depreciated assets comprising a greater percentage of the total. Further investigation into the nature of asset additions and disposals would be beneficial.

The net value of property, plant, and equipment exhibited volatility over the five-year period. A decrease was observed from 2021 to 2022, followed by increases in subsequent years, culminating in a notable rise from 2024 to 2025. Depreciation expense generally decreased from 2021 to 2023, then stabilized before remaining relatively consistent. Simultaneously, the estimated remaining life of these assets increased steadily throughout the period.

Net Property, Plant, and Equipment

The net book value of property, plant, and equipment decreased from US$26,003 million in 2021 to US$23,548 million in 2022, representing a decline of approximately 9.6%. This was followed by increases to US$24,552 million in 2023 and US$24,775 million in 2024. A significant increase to US$28,260 million was recorded in 2025, suggesting substantial additions or revaluations of assets during that year.

Land and Improvements

The value of land and improvements remained relatively stable, fluctuating between US$1,045 million and US$1,188 million. A slight decrease was noted from 2021 to 2022, followed by a gradual increase through 2025. This component represents a small portion of the overall property, plant, and equipment base.

Depreciation Expense

Depreciation expense decreased from US$3,912 million in 2021 to US$3,266 million in 2023, indicating a potential reduction in the depreciable base or a change in depreciation methods. The expense stabilized at US$3,226 million in 2024 and US$3,246 million in 2025, suggesting a consistent level of asset consumption during those years.

Estimated Remaining Life

The estimated remaining life of the property, plant, and equipment increased from 6 years in 2021 and 2022 to 7 years in 2023 and 2024, and further to 8 years in 2025. This increase could be attributable to several factors, including asset upgrades, improved maintenance practices extending asset usability, or a reassessment of useful lives. The lengthening of the estimated remaining life would contribute to lower annual depreciation expense, all other factors being equal.

The combination of increasing estimated remaining life and relatively stable depreciation expense suggests a potential shift in the company’s asset management strategy or a change in the composition of its asset base towards longer-lived assets. The substantial increase in net property, plant, and equipment in 2025 warrants further investigation to determine the nature of the additions or revaluations.
