Convertible Preferred Stock

8. Convertible Preferred Stock and Warrants

Convertible Preferred Stock

TransMedics, Inc. issued Series A-1 convertible preferred stock (the “Series A-1 Preferred Stock”), Series B convertible preferred stock (the “Series B Preferred Stock”), Series B-1 convertible preferred stock (the “Series B-1 Preferred Stock”), Series C convertible preferred stock (the “Series C Preferred Stock”), Series D convertible preferred stock (the “Series D Preferred Stock”), Series E convertible preferred stock (the “Series E Preferred Stock”) and Series F convertible preferred stock (the “Series F Preferred Stock”). The Series A-1 Preferred Stock, Series B Preferred Stock, Series B-1 Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E Preferred Stock and Series F Preferred Stock are collectively referred to as the “Preferred Stock”.

Immediately prior to the closing of the IPO on May 6, 2019, all of the outstanding shares of convertible preferred stock of TransMedics were converted into an aggregate of 13,119,424 shares of common stock of TransMedics Group.

Warrants

TransMedics had outstanding warrants to purchase shares of Series D Preferred Stock and Series F Preferred Stock as of December 29, 2018. The Company classified all of its preferred stock warrants as a liability on its consolidated balance sheets because the warrants were freestanding financial instruments that could require TransMedics to transfer assets upon exercise. The liability associated with each of these warrants was initially recorded at fair value upon the issuance date of each warrant and subsequently remeasured to fair value at each reporting date.

Immediately prior to the closing of the IPO on May 6, 2019, all of the outstanding preferred stock warrants of TransMedics were converted into warrants to purchase an aggregate of 64,440 shares of which warrants to purchase 50,000 shares of common stock at an exercise price of $8.75 per share expire on November 7, 2022 and warrants to purchase 14,440 shares of common stock at an exercise price of $17.47 per share have an expiration date of May 6, 2024. Upon conversion, the fair value of the warrant liability at that time was reclassified to common stock. As a result, subsequent to the closing of the Company’s IPO, the Company no longer remeasures the fair value of the warrant liability at each reporting date.
