Nonrecourse Related-Party Promissory Notes As of December 31, 2020, the Company had promissory notes from certain of the Company’s executive officers, as well as a founding employee and an executive chairman. The promissory notes, which were issued to the Company by the related parties as consideration for the exercise of stock options, were considered nonrecourse notes for accounting purposes. The loans were secured by the shares of Hims Class A common stock held by the individuals. There were 16,345,627 shares of Hims Class A common stock securing the related-party promissory notes as of December 31, 2020. The related-party promissory notes bore interest between 2.2% and 3.0% per annum. The loans were due upon the earliest of (1) ten years from the debt issuance date, (2) a liquidation of the Company, or (3) six months following an initial public offering pursuant to an effective registration statement under the Securities Act of 1933, as amended. Prepayment of principal and interest could be made at any time without penalty. The nonrecourse related-party promissory notes are not given accounting effect until the notes are repaid in full as the underlying stock options are not considered exercised for accounting purposes. As of December 31, 2020, the total outstanding balance under these promissory notes was $7.2 million. In connection with the Merger, the obligations due under all nonrecourse related-party promissory notes were satisfied through the receipt of $1.2 million in the aggregate and the forfeiture of an aggregate 370,734 shares of Hims Class A common stock. The related-party promissory notes were settled within additional paid-in capital on the condensed consolidated balance sheet.

Under the terms of the vendor service agreement with the third party, the purchasers were granted a put right entitling them to sell the shares to the Company at $6.11 per share for a period of six months. The put right expired on March 23, 2020 without the purchasers exercising their rights to sell the shares to the Company. The Company recorded stock-based compensation expense associated with the transaction of $3.0 million.
