A company sufficiently large enough for such an amount to not be a big deal will have a money disbursal process nobody understands enough to make a one time transaction of that size in a reasonable amount of time.
Maybe a company so large it can’t track its own finances is too large to be responsible for its obligations and should be held to standards at least as strict as its less capable business and human peers. And I’m an Apple fan to be clear. But their wealth is the opposite of an excuse.
It isn’t that finances aren’t tracked. They are tracked and audited and the audits are audited and there are many safeguards in place so that money doesn’t leak out and the knowledge for that operation is specialized, so much so that entire departments handle only part of the process and can’t just talk to one another due to the “segregation of duties” the auditors want. A company that decided to incentivize bug bounty like Google got support for the program on high and all the wheels of the org went to work to create policy, procedure, forms, auditor review, SARBOX compliance, etc and payouts will move like any other invoice. A company where some mid rank sees a need for such a program but doesn’t get full organizational alignment will be stuck with a pre-broken unreliable process.
That's still an organization that's too large or mismanaged to be trusted. We trust people who are capricious with their personal finances far less. A large organization with wealth impossible to humans but systems failing them and everyone else who depends on it... is a large corporation with wealth that has no excuse for not solving it.
That's not an excuse. It's just a blunt explanation. Out of the ordinary processes can only proceed so quickly in the presence of massive bureaucracy.
Finance can always be subverted by management, but it has to be a priority.
