On my estimates they have $500k-$1m in the bank currently. They have further payouts to make for the DLA acquisition in October this year (granted that is some time away). They will need $1-$2m to fund the international sales and marketing for ES2.0, and further capital to fund ongoing development of ES (Es2.0 will become ES2.5, 3.0, etc). They also need capital to fund the contract wins. ES2.0 pulls in data from monitoring equipment that is very expensive. Some clients have this equipment already while others will need to purchase it, on some occasions this will be an upfront cost to PEH (though lease arrangements may be entered in to), in government contracts like the WestConnex deal the gov may assist in the funding of the hardware.

The SP may keep rocketing, and for holders I hope it does (I may become a holder again soon) but I'm not sure why you think they aren't in need of capital.
