no question - for example,
if you have a company with 100,000 shares outstanding and the stock is valued at $2 = $200,000 market cap.
a 1 for 10 reverse would net 10,000 shares @ $20. same market cap. nothing changes.
but if you have round ups, more shares are created depending on how much was rounded and and by how many share holders. if 50 stockholders had 100 pre split and retained 100 shares due to the 100 share min roundup the number of shares is now greater than 10,000. for simplicity lets say that bumps up the shares outstanding to 14,500. price drops to the $13's to maintain the same market cap.
that is why is asked about your $45 number given nobody can truly know without access to the roundup information.
there are numerous holders of 1 share odd lots. whether there is enough round up to skew the split i do not know.
