Apologies, I’m a former partner but have a soft spot for y’all and was curious about the question: how long could Starbucks last, based on public info, with paying folks full time but stopping bringing in money? This is information that I think is more useful for y’all than it is for the wider audience of the main sub so here goes:

Starbucks 10-k is here: https://s22.q4cdn.com/869488222/files/doc_financials/2019/2019-Annual-Report.pdf

Starbucks' total operating expenses are $22,728.7M(illion) for 2019, down to $22,533.6M once you take out restructuring and depreciation and amortization expenses. That means the company burns about $394.88M/week to operate the business (probably low, but we're going quick and dirty here). If they were to suspend operations at corporate stores and STOP paying baristas, that would go down pretty significantly, but we're looking at how long they could pay y'all and not operate the stores, so we'll ignore that (it's more an interesting question for the corporate types).

Cash and Cash equivalents in September was $2,686.6M.

Licensed Store Revenue and Other Revenue (bottled drinks, packaged coffee, etc etc, lots of licensing) combined are $$4,964.2M, or $95.47M/week. Other Revenue alone is $2,089.2M/year or $40.18M/week.

Now the fun bits. If we assume all revenue ceases and Starbucks is just using Cash on hand to operate, they could possibly operate about 6 weeks with the stores closed based on these numbers (you can only round down, here). If licensed stores remained open (no determination on if y'all would be paid, that's different balance sheets, sorry) and/or licensed store revenue is not much impacted by a shut down (what the current plan seems to be), Starbucks could stretch paying rent and employees out to about 9 weeks. Assuming licensed stores close (more likely IMO) you'd be talking about 7 weeks of being able to operate.
I'm skipping pretty much all of the subtleties of the statements, here. I suspect that the amount of time they could sustain ceasing ops would be less without taking out some kind of loan to pay for it (and lots of corporate lending is getting shut down right now).

What this current scheme looks like from the outside is them trying to stretch that period: they can comfortably (sort of) manage pay for that long but they’re hedging their bets because, like every company right now, they’re expecting this to last into the summer. I haven’t dug into the quarterlies but I suspect their cash is usually a bit higher riding into this time of year, so they might be able to sustain that for longer.
