Businesses operate "lean", and if they need more money to weather the rainy days, they can issue bonds, or ask the shareholders to inject more capital.
And to make mattes even "leaner" basically market forces pushed risk management out to "specialists" too. Underwriting, counterparty risk, credit risk, traditional insurance, "default insurance" are all just financial products now, that can be built into standard language of shipping contracts.

The tax code is set up with the assumption that corporations are pass-throughs -- they either re-invest funds or pay them out. Funds paid out are taxed as capital income by the recipient (often called "double taxation"). Corporations that sock away cash for a rainy day are viewed as evading this double taxation and are penalized rather harshly. This is another reason (but not the primary reason) why if you want to keep cash for a rainy day you need to have it overseas somewhere where the IRS can't penalize you for holding it.
Or course if that pile gets too big this won't fly.
I recall an article a few years back saying Apple is the largest hedge fund in the world, run buy a small office in Reno NV - and they had a gigantic cash reserve sitting in the bank:
So it doesn't matter if Apple has a trillion dollar in the bank just sitting. The central bank will conduct open market operations to lower the rates of credit so people/companies are incentivized to start new ventures, finally invest in upgrading their old shit, buy a house with a lower APR, etc. And similarly when Apple starts "dumping money into the economy" the Fed will promptly raise rates to keep inflation in check.
Technically for those particular shell companies, yes likely.
For the general offshore companies (like Apple's), a very big yes.
This is a very accessible and detailed paper about how FDI (foreign direct investment) through offshore companies work, and how the high-tax-regime countries benefit the most (eg. the US): https://repository.law.umich.edu/cgi/viewcontent.cgi?article...
