On December 22, 2022, the Company received a written notice from Nasdaq that the Company was eligible for a second 180 calendar day compliance period, or until June 19, 2023, in order to regain compliance with the $1.00 minimum bid price requirement. Nasdaq’s determination to grant the second compliance period was based on the Company meeting the continued listing requirement for market value of publicly held shares and all other applicable requirements for initial listing on The Nasdaq Capital Market, with the exception of the minimum bid price requirement, and the Company’s written notice of its intention to cure the deficiency during the second compliance period by effecting a reverse stock split, if necessary.

The Company anticipates that its shares of common stock and warrants will continue to be listed and traded on The Nasdaq Capital Market during the compliance period ending June 19, 2023. In order to achieve compliance with the minimum closing bid price requirement, the Company filed a proxy statement with the SEC to hold a special meeting of stockholders on May 26, 2023 to seek stockholder approval to approve an amendment to the Company’s Certificate of Incorporation to effect a reverse stock split of the issued and outstanding shares of the Company’s common stock at a split ratio of up to a maximum of a 1-for-10 split, as determined by the Board of Directors in its sole discretion. However, there can be no assurance that the Company will be successful in obtaining stockholder approval and will thus be able to regain compliance with the minimum closing bid price requirement by June 19, 2023, in which case the Company anticipates Nasdaq would provide a notice to the Company that its shares of common stock and warrants are subject to delisting, and the Company’s common shares and warrants would then be delisted. Even if the Company is able to achieve compliance with Nasdaq’s minimum closing bid price requirement, there can be no assurances that the Company will be able to maintain compliance with Nasdaq’s other continued listing requirements.

Operating results for the interim periods presented are not necessarily indicative of the results to be expected for a full fiscal year. The consolidated balance sheet at December 31, 2022 has been derived from the Company’s audited consolidated financial statements at such date.

The condensed consolidated financial statements and related notes have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the financial statements and other information included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as filed with the SEC.

Nasdaq Notification of Failure to Satisfy a Continued Listing Rule

The Company’s common stock and the warrants are traded on The Nasdaq Capital Market under the symbols “LIXT” and “LIXTW”, respectively.

On June 24, 2022, the Company received a written notice (the “Notice”) from The Nasdaq Stock Market LLC (“Nasdaq”) that the Company had not been in compliance with the minimum bid price requirement set forth in Nasdaq Listing Rule 5550(a)(2) for a period of 30 consecutive business days. Nasdaq Listing Rule 5550(a)(2) requires listed securities to maintain a minimum closing bid price of $1.00 per share, and Nasdaq Listing Rule 5810(c)(3)(A) provides that a failure to meet the minimum closing bid price requirement exists if the deficiency continues for a period of 30 consecutive business days. The Notice had no immediate effect on the listing of the Company’s common stock on The Nasdaq Capital Market.

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company was provided a compliance period of 180 calendar days from the date of the Notice, or until December 21, 2022, to regain compliance with the minimum closing bid price requirement. On December 22, 2022, the Company received a written notice from Nasdaq that the Company was eligible for a second 180 calendar day compliance period, or until June 19, 2023, in order to regain compliance with the $1.00 minimum bid price requirement. Nasdaq’s determination to grant the second compliance period was based on the Company meeting the continued listing requirement for market value of publicly held shares and all other applicable requirements for initial listing on The Nasdaq Capital Market, with the exception of the minimum bid price requirement, and the Company’s written notice of its intention to cure the deficiency during the second compliance period by effecting a reverse stock split, if necessary.

The Company can generally achieve compliance with the minimum closing bid price requirement if the minimum closing bid price of the Company’s common stock is at least $1.00 per share for a minimum of 10 consecutive business days during the 180-day compliance period. However, under certain circumstances, Nasdaq can extend this 10-day trading period up to a maximum of 20 days. The Company anticipates that its shares of common stock and warrants will continue to be listed and traded on The Nasdaq Capital Market during the compliance period ending June 19, 2023.

In order to achieve compliance with the minimum closing bid price requirement, the Company filed a proxy statement with the SEC to hold a special meeting of stockholders on May 26, 2023 to seek stockholder approval to approve an amendment to the Company’s Certificate of Incorporation to effect a reverse stock split of the issued and outstanding shares of the Company’s common stock at a split ratio of up to a maximum of a 1-for-10 split, as determined by the Board of Directors in its sole discretion. However, there can be no assurance that the Company will be successful in obtaining stockholder approval and will thus be able to regain compliance with the minimum closing bid price requirement by June 19, 2023, in which case the Company anticipates Nasdaq would provide a notice to the Company that its shares of common stock and warrants are subject to delisting, and the Company’s common shares and warrants would then be delisted.

Even if the Company is able to achieve compliance with Nasdaq’s minimum closing bid price requirement, there can be no assurances that the Company will be able to maintain compliance with Nasdaq’s other continued listing requirements.
