| Convertible preferred stock | Convertible preferred stock During October, 2020, the Company consummated an insider-led equity financing, including the transactions contemplated by a securities purchase agreement (the “Securities Purchase Agreement”) between the Company and certain accredited and sophisticated investors (the “Purchasers”) and an exchange agreement (the “Series E Exchange Agreement”) between the Company and Cavalry Fund LP ("Cavalry"), the holder of all of the Company’s previously outstanding Series E preferred stock.
Pursuant to the Securities Purchase Agreement, the Company, in a private placement (the “Series F Private Placement”), issued and sold units (the “Series F Units”) to the Purchasers for a purchase price of $1,000 per Unit. Each Unit consisted of: (i) one share of the Company’s Series F convertible preferred stock, par value $0.001 per share (the “Series F Preferred Stock”), which is convertible into shares of the Company’s common stock, par value $0.001 per share, at a value per share of common stock of $3.00; and (ii) a warrant to purchase for a six year period such number of shares of common stock (the “Series F Warrant Shares”) into which such share of Series F Preferred Stock is convertible at an exercise price per Warrant Share of $4.50. Pursuant to the Series F Private Placement, the Company raised approximately $18.2 million in gross cash proceeds, approximately $6.5 million of which was invested by certain officers, directors, employees and associated related parties thereto of the Company. The Series F Units were recorded at fair value on the date of issuance on an as converted basis.
Concurrently with the execution of the Securities Purchase Agreement, the Company and the Purchasers entered into a registration rights agreement, (as amended by a certain first amendment, dated October 29,2020, the "Registration Rights Agreement") pursuant to which the Company filed a registration statement to register the Warrant Shares and the shares of common stock issuable upon conversion of the Series F Preferred Stock.
In connection with the consummation of the Series F Private Placement, on October 1, 2020, the Company filed with the Secretary of State of Delaware a Certificate of Designations which authorizes a total of 30,000 shares of Series F Preferred Stock and sets forth the designations, preferences, and rights of the Company's Series F Preferred Stock.
On October 1, 2020, the Company issued 14,264 Series F Units in connection with the Series F Private Placement. In addition, pursuant to the Series E Exchange Agreement, on October 1, 2020, the Company issued 3,500 Series F Units to Cavalry in exchange for all of its outstanding Series E Preferred Stock. The exchange of Series E Preferred Shares resulted in a $5.4 million gain and was recorded to Accumulated deficit on the Company's Consolidated Balance Sheets. On October 12, 2020 and October 23, 2020, the Company issued 1,106 and 2,832 Series F Units, respectively, in connection with the Series F Private Placement. In addition, on October 23, 2020, the Company issued an additional 100 shares of Series F Preferred Stock in conjunction with a marketing agreement.
The Company evaluated the conversion option within the Series F Preferred Stock on the dates of issuance to determine whether the conversion price was beneficial to the holders. The Company recorded a BCF related to the issuance of the Series F Preferred Stock. The BCF was recognized and measured by allocating a portion of the proceeds to the beneficial conversion feature, based on fair value and was recorded to Accumulated deficit on the Company's Consolidated Balance Sheets limited to the proceeds amount allocated to the instrument.
On July 1, 2021, all outstanding shares of convertible preferred stock were converted to common stock in connection with the consummation of the Company's IPO. See "Note 1 - Nature of business and summary of significant accounting policies" for additional information.
