Absolutely. This should also be on the list of questions you should ask before you go to work at a startup. You probably wouldn't ask these on a first interview, but as you get close to the offer stage asking questions about money in the bank, burn rate, cash out date and such are fair game.
If the company will not answer those questions, that in itself is useful data for guiding your decision making. :)
Management should be sharing it with you at least quarterly if not monthly. Typically, I've seen it done the day after or the Friday after the most recent Board meeting.
