Depends on how the warrants were set up originally. I assume they will be adjusted for any splits. If not, as soon as the split is realized, they'll be in the money! TedJ usually has a handle on these types of details. Perhaps he will help out us lay people. ;)
OK let’s take an example with our current warrants which run now about 50 cents, plus or minus. By 2022 we can purchase one share at $4 by exercising one warrant.. With the r/s what will we have???
