Because they moved some costs out of the operating expenses and into investing activities. Those expenses are R&D in nature and are expected to be offset every year by the R&D rebate (a good chunk of it). The next 4C should show a receipt of circa $1.5mio from such rebate for FY24. If they operate at a too tight runway, they may need to borrow against future R&D receivables.
Also, the cash position used in these calcs does not consider the "net client book", and should be $4.8mio instead.
If you take the above into consideration, the runway was a lot tighter, circa 2.5 quarters. But they are following the conventions of this report, not doing anything wrong and the R&D rebate receipt will extend it.
This 4C will somehow "reset" the financials: R&D rebate received, consolidation of Limepay acquisition, validation or not of the announced progress with CC. Very difficult to predict. I fear the Limepay acquisition will not be positive to the bottom line. If it was, SPX would not have been able to acquire it. And I just ignore any new revenues announcement until I see them confirmed in 4C.
If we fast forward 8 months, the options expiring in August look under water. At which stage does this impact their financial risk management? Something for the new CFO...
