How much will AI spending inflate hyperscaler depreciation expenses?
Core argument: Morgan Stanley's Accounting & Tax desk calculates that Oracle's $4bn 2025 depreciation charge could reach $56bn by 2029, equivalent to 28% of the revenue consensus expects for that year.
Because tech companies rarely break out depreciation in their income statements, analysts often take a blunt approach and model the effect through cash flow, then fiddle with their operating margin estimates until everything hangs together. During periods of high investment in assets whose useful lives are very different, namely GPUs and warehouses, the analyst has a very high chance of being wrong. Morgan Stanley’s Accounting & Tax desk, led by analyst Todd Castagno, takes a more granular approach. The team splits hyperscaler capex into AI and non AI, smooths out construction-in-progress costs, and allocates the expected lease expenses to property. The team assumes GPUs have a useful life of up to six years and that warehouses will last for 15 years. Based on Morgan Stanley’s calculations, Alphabet’s depreciation expense could quadruple by its 2028 year-end. Oracle’s 2025 depreciation charge of $4bn might balloon to $56bn by 2029, which would be equivalent to 28% of revenue expected by the consensus. Unless forecasts move significantly higher, depreciation will soon come to dominate total expenses.
