Not all cash is fungible for CapEx. For instance, much of that might hypothetically be held in an offshore account. Building a datacenter with it would trigger unfavorable VAT or sales tax or something... Hypothetically...

High cap companies use debt for this: bank loan is located in the market where it's needed most, and the debt is serviced by interest earned from securities in other markets. The net taxes are a small percent (think 3%) relative to simply transferring funds within the company. Yes, this is the low effective tax rate the EU is quite upset about.

Other reasons for not touching their holdings usually have a similar explanation. The securities are fungible for accounting purposes but not fungible enough for actual day-to-day operations. Result: securities get "stranded" and the large company grows a hedge fund appendage.

Yeah, for profitable companies, debt is a strategic tool not a desperate act. It more about orchestrating around the money that is soft locked somewhere else.
