IMNN split history picture
Imunon (IMNN) has 2 splits in our IMNN split history database. The first split for IMNN took place on July 25, 2025. This was a 1 for 15 reverse split, meaning for each 15 shares of IMNN owned pre-split, the shareholder now owned 1 share. For example, a 1000 share position pre-split, became a 66.6666666666667 share position following the split. IMNN's second split took place on August 07, 2025. This was a 115 for 100 split, meaning for each 100 shares of IMNN owned pre-split, the shareholder now owned 115 shares. For example, a 66.6666666666667 share position pre-split, became a 76.6666666666667 share position following the split.

When a company such as Imunon splits its shares, the market capitalization before and after the split takes place remains stable, meaning the shareholder now owns more shares but each are valued at a lower price per share. Often, however, a lower priced stock on a per-share basis can attract a wider range of buyers. If that increased demand causes the share price to appreciate, then the total market capitalization rises post-split. This does not always happen, however, often depending on the underlying fundamentals of the business. When a company such as Imunon conducts a reverse share split, it is usually because shares have fallen to a lower per-share pricepoint than the company would like. This can be important because, for example, certain types of mutual funds might have a limit governing which stocks they may buy, based upon per-share price. The $5 and $10 pricepoints tend to be important in this regard. Stock exchanges also tend to look at per-share price, setting a lower limit for listing eligibility. So when a company does a reverse split, it is looking mathematically at the market capitalization before and after the reverse split takes place, and concluding that if the market capitilization remains stable, the reduced share count should result in a higher price per share.

Looking at the IMNN split history from start to finish, an original position size of 1000 shares would have turned into 76.6666666666667 today.
