Have to agree. I factored in a 35% increase in cash receipts, but was met with +25%.
One thing i perhaps haven't taken account of is growing receipts from a commercialized Indonesia. In the past Q2 - Q4 has been relatively flat after a step change in Q1. Perhaps the growing Indonesian revenue & receipts will prop up these quarters a little more?

In any case, i'm in the same boat as you - it's tight.... very tight. They keep guiding to EBITDA positive - but that's not the number that keeps you solvent - its the cash balance, and that one i don't have turning positive till 2021 (unless a bunch of oppies get excercised or Indonesia revenue ramps up considerably).
