From my understanding this means that palantir has enterred a new agreement where it can loan up to 500 million total, 400 million from existing lenders and 100 million from new or existing lenders. Simultaneously they paid off their prior 200 million loan and are currently debt less. What this means is that this is nothing more than a mere updating ofa lending agreement, allowing them to borrow more than what they were previously allowed for future growth. With interest rates rising soon, especially with unemployment datatrending positively,securing greater sources of cash flows earlier might prove a smart move to secure more growth funds if necessary at a cheaper cost. This is completely my opinion and may be wrong.
