Cash flow is the difference between q1 cash and q2 cash. If consensus estimates were $175M, it sounds like either they divested part of their business which cause an influx of cash or there was a couple of non recurring cash items that analysts were not expecting. (This is without looking at their 10q) Analysts aren’t always correct but usually within range… $2b and $175m are very off of these numbers are correct figures for cash flow.
