Pinned straw:
There could be some adverse timings in a single quarter. Perhaps there were some lumpy sales receipts in the prior quarter with suppliers getting paid in this quarter.
Nevertheless, last time I looked, UBI needed about $2.7M / qtr to break even and this is trending in the wrong direction.
At the last qtr burn rate they are out of cash in two quarters. If we add back the one-offs, they've got 3 quarters to make good, ie end of calendar 2024 else need a CR. That's why the SP tumbled. They can't afford another bad quarter and the chance of a really good one seems remote.
