I think not (rather, it depends), if they listed the day after say receiving a wire transfer of the amount, their NAV would only be higher by the $500M, so in a sensible world, investors would be buying the cash along with other assets essentially. This wouldn't pump up the fair value, as there would be a dilution (or likely anti-dilution) aspect to the NAV of each share post the transaction.
If on the other hand, they were to find immediate use for that amount, they could justify it being put into tangible and intangible assets whose fair value is higher than book value. Though since the grandparent poster states that they already make $250M in revenue, if they are making a net profit, the cash will only be useful in the medium to long-term for expansion.
