Space stocks cash runway ranking

Most space companies still spend more cash than they bring in. Cash runway estimates how long each one could keep going on the cash it has today if it kept burning money at the same rate, before it would need to raise more by selling shares or borrowing. A short runway is one of the clearest signs that a share offering, and dilution for existing holders, may be coming.

How runway is worked out

Runway is cash and short-term investments divided by the average monthly free cash outflow over the last 12 months. Free cash flow is operating cash flow minus capital spending, taken from the figures companies tag in their 10-Q and 10-K filings.

What it leaves out

It is a rough guide, not a forecast. It ignores undrawn credit lines, money still to come from at-the-market share programmes, and large contract payments due in future. Capital spending in this industry is lumpy, so a year with a big satellite or factory build can make runway look shorter than the underlying business would suggest. A company that has just raised money will look much healthier the quarter after the cash arrives. Check the latest filing before drawing conclusions.

Companies that report in currencies other than US dollars, and those that do not file with the SEC, are not included.
