No. I think they have will need to raise debt. Not saying it will happen, but it might.
By way of comparison, TDG is very proactive. They raised debt, and said it was insurance against a longer downturn. I like that strategy: raise debt when it’s available, not when you need it. I still don’t understand why HEI hasn’t done this. Maybe their covenants are too restrictive, or their cash burn much smaller than TDG.
I think it is because they have the non-aerospace business that is producing cash still so not necessary. TDG has a lot of leverage - wouldn't you rather a fresh balance sheet if this is becomes a prolong contraction? Management is surely in talks with banks regularly, I would feel pretty confident they could easily get financing if needed even in a pretty dire scenario.
Heico management has said at least a couple times that for the right opportunity(ies), they'd be ready to lever up 6-7x (iirc), as long as they knew they'd be able to delever relatively quickly after that.
