4. Average maintenance capital expenditure over a business/industry cycle: 5-Year Average Maintenance Capital Expenditure = $24 Mil
It is usually best to take a long-term average of maintenance capital expenditure. Ideally this would be as long as 10 years and include at least one economic downturn. However, since many companies do not have as long as 10-year history, here GuruFocus uses the latest 5 years data to do the calculation. To smooth out unusual years but reflect recent developments, we take an average of the 5 year maintenance capital expenditure.
The following shows how to get maintenance capital expenditure.
First, calculate the revenue change regarding to the previous year. If the revenue decreased from the previous year, then the Maintenance Capital Expenditure = Capital Expenditure (positive).
Second, if the revenue increased from the previous year, then calculate the percentage of Net PPE as of corresponding Revenue.
Growth Capital Expenditure = Percentage of Property, Plant and Equipment as of corresponding Revenue * Revenue Increase
Third, calculate Capital Expenditure (positive) - Growth Capital Expenditure.
If [Capital Expenditure (positive) - Growth Capital Expenditure] was negative, then the Maintenance Capital Expenditure = Capital Expenditure (positive).
If [Capital Expenditure (positive) - Growth Capital Expenditure] was positive, then the Maintenance Capital Expenditure = Capital Expenditure (positive) - Growth Capital Expenditure.
Fourth, get the average of the 5 years maintenance capital expenditure.
SIA Engineering Co's 5-Year Average Maintenance Capital Expenditure = $24 Mil
5. "Change In Working Capital" is from cashflow statement. SIA Engineering Co's Change In Working Capital for the trailing twelve months (TTM) ended in Mar. 2026 was $-61 Mil.
Note: GuruFocus' Change in Working Capital is provided by Morningstar.
