| Item 3.01. | Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing. |
As previously reported, on August 24, 2022,
Humanigen, Inc. (the “Company”) received a letter from the Listing Qualifications Department (the “Nasdaq Staff”)
of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that it was not in compliance with Nasdaq Listing Rule 5550(a)(2),
as the minimum bid price of the Company’s common stock had been below $1.00 per share for 30 consecutive business days. In accordance
with Nasdaq Listing Rule 5810(c)(3)(A), the Company was granted a period of 180 calendar days, or until February 20, 2023, to regain compliance
with the minimum bid price requirement.
As previously reported, on October 3, 2022,
the Company received a letter from the Nasdaq Staff notifying the Company that it was not in compliance with Nasdaq Listing Rule 5550(b)(2),
as the Company’s market value of listed securities (“MVLS”) had been below the required minimum of $35 million for 30
consecutive business days. In accordance with Nasdaq Listing Rule 5810(c)(3)(C), the Company was granted a period of 180 calendar days,
or until April 3, 2023, to regain compliance with the minimum MVLS requirement.
As previously reported, on February 21, 2023, the Company received
a letter from the Nasdaq Staff notifying the Company that because it had not regained compliance with the minimum bid price requirement
as of February 20, 2023, and was not eligible for a second 180 day extension period, the Company’s securities would be suspended
from trading on and delisted from The Nasdaq Capital Market, unless the Company timely requested a hearing before a Nasdaq Hearings Panel
(the “Panel”) to appeal Nasdaq’s delisting determination. The Nasdaq Staff’s letter also specifically noted that
the Company does not comply with the stockholders’ equity initial listing requirement for the Nasdaq Capital Market.
As previously reported, the Company timely requested a hearing before
the Panel to appeal Nasdaq’s delisting determination, which such hearing was scheduled for April 6, 2023 (the “Hearing”).
On April 5, 2023, prior to the Hearing, the Company
received a letter from the Nasdaq Staff notifying the Company that it had not regained compliance with the minimum MVLS requirement as
of April 3, 2023 and that this deficiency would serve as an additional basis for delisting the Company’s securities from Nasdaq.
The Nasdaq Staff’s letter also informed the Company that the Panel would consider, and the Company should address, this additional
deficiency at the Hearing.
At the Hearing held before the Panel on April 6, 2023, the Company
outlined its plans for regaining compliance with the minimum bid price requirement, the minimum MVLS requirement, and other applicable
requirements for listing on the Nasdaq Capital Market, and requested a 180-day extension, until August 21, 2023, to regain compliance
with all applicable requirements.
A decision from the Panel is expected within 30 days. The suspension
and delisting of the Company’s common stock from The Nasdaq Capital Market has been stayed pending completion of the hearing process
and the expiration of any extension period that may be granted by the Panel, not to exceed 180 days from February 21, 2023. There can
be no assurance that the Company will be granted an extension to regain compliance or, if granted, that the Company will regain compliance
with the minimum bid price requirement, the minimum MVLS requirement or other Nasdaq listing requirements within the extended compliance
period.
