Reverse Stock Split: What Is It, and Why Do Companies Use One?

A reverse stock split combines several existing shares into one. In a 1-for-20 split, every 20 shares become one and the price per share is multiplied by roughly 20, so the value of each holder's position is unchanged at that moment.

The most common reason is Nasdaq's $1.00 minimum bid price. Companies announce splits to lift the quoted price above that line, as several recent notices show. The split changes the share count and not the business.

Sunshine Biopharma and Top Wealth: How Do the Mechanics Play Out?

Sunshine Biopharma (NASDAQ:SBFM) reported a 1-for-20 split on Thursday, October 22, effective at market open on Monday, October 26, to regain compliance with the bid price rule. Shares were trading down 21.15% at $0.1699, which at 20 times is roughly $3.40 in advance of any post-split move, calculated. The count falls from 15,219,383 to roughly 760,969.

Top Wealth Group (NASDAQ:TWG) completed a 1-for-100 consolidation of Class A and Class B shares at the open on October 22, approved by its board and shareholders on September 29. With a market capitalization near $4.2 million, calculated from the company's figures, Shares were trading down 28.59% at $0.0482.

Hub Cyber Security (NASDAQ:HUBC) shows how repeated splits compound. It reported ratios of 1-for-50 on April 16, 1-for-20 on June 3 and 1-for-25 on September 10, a combined 25,000-to-1, calculated. The September step cut shares from roughly 44.9 million to roughly 1.8 million.

Nasdaq Rules: Which Limits Apply to a Reverse Split?

Under Nasdaq Rule 5250(e)(7), a company must file a notification form by noon Eastern at least 10 days in advance of the effective date, and Rule 5250(b)(4) requires public disclosure at least two business days in advance of. Nasdaq will not process a split that misses these steps and may halt trading.

Rule 5810(c)(3)(A)(iv) adds limits. A company that effected a reverse split in the prior one-year period, or splits with a cumulative ratio of 250-to-1 or more over two years, receives no compliance period for a bid price deficiency. Staff issues a delisting determination instead, as in the case of PomDoctor (NASDAQ:POM), which had split 1-for-18 on June 22.

The result can be a thin float. CytoSorbents (NASDAQ:CTSO) split 1-for-20 effective September 8, and Nasdaq confirmed on September 22 that the $1.00 minimum was met after 10 consecutive trading days. A free float of roughly 2.64 million shares can amplify moves in either direction.

After the Split: What Should Investors Watch Next?

The first test is whether the split-adjusted price holds above $1.00 for 10 consecutive business days. Financing near the split matters too: Sunshine Biopharma priced a $6.0 million offering at $0.55 per unit on October 8. Other compliance items may stay open, for example the market value requirement CytoSorbents must meet by December 28, 2026.
