There are no formal limits on how many times a company can perform reverse stock splits, but there are practical limits. The company must maintain at least 500,000 outstanding shares to stay listed on the NASDAQ and 200,000 to stay on the NYSE. Each reverse split reduces the number of shares a company has. Companies may conduct their splits using any ratio, but to achieve compliance with NASDAQ, share prices must stay above $1 for at least 10 days.
