I don’t see any rseason the time frame will change split or no split, just like the time frame to making earnings will be the same either way. I’ve had several stocks I own split with no affect to the P/E. I don’t expect a reverse split, for good reasons to change market cap, earnings, time to earnings or P/E in any any meaningful way.
Investors, especially retail investors don’t look at just share price to determine if a stock is over or under valued. Actual market cap vs potential market cap will be a big focus until the mine is in production, then P/E will factor in heavily.
Dividend payouts, if any are also unaffected by a split or reverse split since they are paid out with earnings per share.
