8. Derivative Liabilities

The Company accounted for the Series F Warrants, Series G Warrants and the Series H Warrants in accordance with ASC 815-10. Since the Company was required to purchase its Series F Warrants, Series G Warrants and Series H Warrants for an amount of cash equal to $36.00, $22.00 and $10.66, respectively, for each share of Common Stock (the "Minimum Value") they are recorded as liabilities at the greater of the Minimum Value or fair value. They are marked to market each reporting period through the Consolidated Statement of Operations.

On the respective closing dates of June 28, 2018 and May 12, 2019, respectively, the derivative liabilities related to the Series G Warrants and Series H Warrants were recorded at an aggregate fair value of $1,628,113. Given that the fair value of the derivative liabilities was less than the net proceeds, the remaining proceeds were allocated to Common Stock and additional paid-in-capital.

On March 10, 2023, Arch Therapeutics, Inc. entered into exchange agreements (the “Exchange Agreements”) with each holder (the “Warrantholders”) of the Company’s outstanding Series G Warrants to purchase shares of the Company’s common stock, par value $0.001 per share at an exercise price of $140.00 per share and the Company’s outstanding Series H Warrants to purchase shares of Common Stock at an exercise price of $80.00 per share. Pursuant to the Exchange Agreements, the Warrantholders exchanged 34,013 Series G Warrants for 3,402 shares of Common Stock and 43,077 Series H Warrants for 8,617 shares of Common Stock.

During the three and nine months ended June 30, 2023, $0 and $1,158,197, respectively was recorded to gain on extinguishment of derivative liability for the exchange of the Series G warrants and Series H warrants and $49,278 was recorded as part of shareholder’s deficit. During the three and nine months ended June 30, 2022, $0 and $1,000,000, respectively was recorded to decrease the fair value of derivative liability related to the expired Series F warrants.
