What Is Property, Plant & Equipment (PP&E)?
PP&E covers the physical assets a company uses to operate over many years rather than sell to customers. Factories, office buildings, land, manufacturing equipment, delivery fleets, and store fixtures all qualify. Because these assets provide benefits over long periods, their cost is capitalized onto the balance sheet when purchased instead of being expensed immediately, then depreciated over their useful lives.
Companies report the figure two ways. Gross PP&E is the original historical cost of everything still owned, while net PP&E subtracts accumulated depreciation, the total depreciation recorded since each asset was placed in service. Net PP&E is the number that appears on the face of the balance sheet, and land is the notable component that is never depreciated because it does not wear out.
How PP&E Moves Through the Statements
The standard roll-forward is Ending Net PP&E = Beginning Net PP&E + Capital Expenditures − Depreciation − Net Book Value of Disposals. Capex, found in the investing section of the cash flow statement, adds to the balance, while depreciation, a non-cash expense on the income statement, steadily reduces it. If a company starts the year with $800 million of net PP&E, spends $150 million on capex, and records $100 million of depreciation, it ends at $850 million.
PP&E can also fall through impairments when an asset's carrying value is no longer recoverable, and it changes in acquisitions when acquired assets are written up to fair value. In models, analysts typically forecast capex as a percentage of revenue and depreciation off the existing and new asset base, making the PP&E schedule one of the key supporting schedules linking the statements.
Why It Matters in Practice
PP&E intensity shapes a company's entire financial profile. Railroads, utilities, telecom carriers, and semiconductor manufacturers hold tens of billions of dollars of PP&E and must reinvest heavily just to maintain capacity, which suppresses free cash flow. Asset-light businesses like software firms convert far more of their earnings into cash. Comparing capex to depreciation is a quick check on whether a company is growing its asset base or letting it shrink.
In interviews, PP&E anchors classic questions such as walking through a $10 increase in depreciation or explaining how buying equipment with debt flows through the statements. It also matters for valuation: lenders view PP&E as collateral, and metrics like return on invested capital hinge on how productively a company sweats these assets.
