Item 8.01. Other Events.

On October 4, 2022, Sonnet BioTherapeutics Holdings, Inc. (the “Company,” “we” or “us”) issued a press release announcing that on October 3, 2022, the Company received a letter from The Nasdaq Stock Market LLC (“Nasdaq”) stating that because the Company’s shares had a closing bid price at or above $1.00 per share for a minimum of 10 consecutive business days, the Company’s stock had regained compliance with the minimum bid price requirement of $1.00 per share for continued listing on the Nasdaq Capital Market, as set forth in Nasdaq Listing Rule 5550(a)(2), and that the matter is now closed. A copy of the Company’s press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

As previously reported, on August 22, 2022, the Company received notice (the “Notice”) from Nasdaq advising the Company that it is not in compliance with the minimum stockholders’ equity requirement for continued listing on The Nasdaq Capital Market. Nasdaq Listing Rule 5550(b)(1) requires companies listed on The Nasdaq Capital Market to maintain stockholders’ equity of at least $2,500,000 (the “Stockholders’ Equity Requirement”). In the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2022, the Company reported stockholders’ equity of $764,205, which is below the Stockholders’ Equity Requirement for continued listing. Additionally, the Company did not meet either of the alternative Nasdaq continued listing standards under the Nasdaq Listing Rules, market value of listed securities of at least $35 million, or net income of $500,000 from continuing operations in the most recently completed fiscal year, or in two of the three most recently completed fiscal years.

The Notice had no immediate effect on the listing of the Company’s common stock and the Company’s common stock continues to trade on The Nasdaq Capital Market under the symbol “SONN,” subject to the Company’s compliance with the other continued listing requirements.

Pursuant to the Notice, Nasdaq has given the Company 45 calendar days, or until October 6, 2022, to submit to Nasdaq a plan to regain compliance. If the Company’s plan is accepted, Nasdaq may grant an extension of up to 180 calendar days from the date of the Notice to evidence compliance.

The Company is currently evaluating various courses of action to regain compliance and plans to timely submit its plan to Nasdaq to regain compliance with the Stockholders’ Equity Requirement. There can be no assurance that the Company’s plan will be accepted or that if it is, the Company will be able to regain compliance. If the Company’s plan to regain compliance is not accepted, or if it is and the Company does not regain compliance within 180 days from the date of Nasdaq’s letter, or if the Company fails to satisfy another Nasdaq requirement for continued listing, Nasdaq could provide notice that the Company’s common stock will become subject to delisting. In such event, Nasdaq rules would permit the Company to appeal the decision to reject the Company’s proposed compliance plan or any delisting determination to a Nasdaq Hearings Panel. The hearing request would stay any suspension or delisting action pending the conclusion of the hearing process and the expiration of any additional extension period granted by the panel following the hearing.

We are not currently in compliance with the continued listing requirements for the Nasdaq Capital Market. If we do not regain compliance and continue to meet the continued listing requirements, our common stock may be delisted from the Nasdaq Capital Market, which could affect the market price and liquidity for our common stock and reduce our ability to raise additional capital.

Our common stock is listed on the Nasdaq Capital Market. In order to maintain that listing, we must satisfy minimum financial and other requirements including, without limitation, the Stockholders’ Equity Requirement.

The Company intends to monitor its stockholders’ equity and may, if appropriate, consider implementing available options to regain compliance with the Stockholders’ Equity Requirement. There can be no assurance that we will be able to regain compliance with the Stockholders’ Equity Requirement or maintain compliance even if we implement an option that regains our compliance.

If we fail to regain compliance with the Stockholders’ Equity Requirement or to meet the other applicable continued listing requirements for the Nasdaq Capital Market in the future and Nasdaq determines to delist our common stock, the delisting could adversely affect the market price and liquidity of our common stock and reduce our ability to raise additional capital. In addition, if our common stock is delisted from Nasdaq and the trading price remains below $5.00 per share, trading in our common stock might also become subject to the requirements of certain rules promulgated under the Exchange Act, which require additional disclosure by broker-dealers in connection with any trade involving a stock defined as a “penny stock” (generally, any equity security not listed on a national securities exchange or quoted on Nasdaq that has a market price of less than $5.00 per share, subject to certain exceptions).
