8. Stockholders’ Equity
Under its certificate of incorporation, the Company was authorized to issue up to 200,000,000 shares of common stock as of December 31, 2021 and December 31, 2020. The Company also was authorized to issue up to 5,000,000 shares of preferred stock as of December 31, 2021 and December 31, 2020. The Company is required, at all times, to reserve and keep available out of its authorized but unissued shares of common stock sufficient shares to effect the conversion of the shares of the preferred stock and all outstanding stock options and warrants.
Registered Underwritten Public Offering
In August 2020, the Company closed a registered underwritten public offering of 25,000,000 shares of its common stock, including the full exercise of a 30 day option to purchase additional shares which we granted to the underwriters, at a public offering price of $2.30 per share. This transaction resulted in net proceeds to the Company of approximately $53.7 million, after deducting underwriting discounts and commissions and offering expenses.
On April 17, 2019, the Company entered into a Common Stock Sales Agreement with H.C. Wainwright & Co., LLC, or Wainwright, pursuant to which the Company may offer and sell through Wainwright, from time to time at the Company’s sole discretion, shares of its common stock, having an aggregate offering price of up to $50.0 million, or the HCW ATM Program. Sales of the shares of common stock are deemed to be “at-the-market offerings,” as defined in Rule 415 under the Securities Act. In December 2020, the Company and Wainwright entered into Amendment No. 1 to Common Stock Sales Agreement, or the Amendment, to amend the Common Stock Sales Agreement to, among other things, update the reference to the registration statement pursuant to which the shares of common stock may be sold and to include an additional $50.0 million of shares of common stock in the HCW ATM Program. For the year ended December 31, 2021, the Company issued and sold approximately 4.3 million shares of common stock under the HCW ATM Program. The net offering proceeds to the Company in 2021 for sales under the HCW ATM Program were approximately $7.9 million after deducting related expenses, including commissions. As of December 31, 2021, there was approximately $41.9 million remaining available for future issuances under the HCW ATM Program.
Registered Direct Offering and Concurrent Warrant Issuance
In January 2019, the Company entered into securities purchase agreements with two institutional investors wherein the Company agreed to sell to the investors an aggregate of 10,000,000 shares of its common stock, at an offering price of $1.00 per share, in a registered direct offering. The net proceeds to the Company from the offering were $9.2 million, after deducting fees and the expenses of the placement agent. Pursuant to a letter agreement dated January 28, 2019, the Company engaged Wainwright to act as its exclusive placement agent in connection with the issuance and sale of the shares. The Company paid Wainwright 7.0% of the aggregate gross proceeds in the offering and $50,000 for certain expenses, and it issued warrants to purchase 500,000 shares of common stock to certain designees of Wainwright. These warrants have a term of five years, are immediately exercisable and have an exercise price of $1.25 per share. During the year ended December 31, 2020, 327,500 of these warrants were exercised in a cashless exercise for 201,925 common shares. The warrants are classified as equity and were recorded at fair value as of the date of issuance on the Company’s Consolidated Balance Sheets and no further adjustments to their valuation are made. The letter agreement also includes indemnification obligations of the Company and other provisions customary for transactions of this nature.
Equity Incentive Plans
In 2008, the Company adopted the 2008 Equity Incentive Plan, as amended on February 29, 2008, January 7, 2010, July 8, 2010, December 10, 2010, June 23, 2011 and June 17, 2013, collectively, the 2008 Plan, that authorized the Company to grant restricted stock and stock options to eligible employees, directors and consultants to the Company.
In 2013, the Company adopted the 2013 Equity Incentive Plan, as amended on May 14, 2014, collectively, 2013 Plan. The 2013 Plan became effective upon the Company’s entry into the underwriting agreement related to its IPO in January 2014 and, as of such date, no further grants were permitted under the 2008 Plan. The 2013 Plan provides for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance-based stock awards and other forms of equity compensation (collectively, stock awards), all of which may be granted to employees, including officers, non-employee directors and consultants of the Company. Additionally, the 2013 Plan provides for the grant of cash and stock-based performance awards. The 2013 Plan contains an “evergreen” provision, pursuant to which the number of shares of common stock available for issuance under the plan automatically increases on January 1 of each year beginning in 2015.
On December 15, 2016, the Company adopted the Trevena, Inc. Inducement Plan, or the Inducement Plan, effective January 1, 2017, pursuant to which the Company reserved 500,000 shares of the Company’s common stock for issuance under the Inducement Plan. The Plan provides for nonqualified stock options and restricted stock unit awards. The only persons eligible to receive grants of awards under the Inducement Plan are individuals who satisfy the standards for inducement grants under Nasdaq Marketplace Rule 5635(c)(4) and the related guidance under Nasdaq IM 5635-1, including individuals who were not previously an employee or director of the Company or are following a bona fide period of non-employment, in each case as an inducement material to such individual’s agreement to enter into employment with the Company.
Under all Plans, the amount, terms of grants and exercisability provisions are determined by the board of directors or its designee. The term of the options may be up to 10 years, and options are exercisable in cash or as otherwise determined by the board of directors or its designee. Vesting generally occurs over a period of not greater than four years. For performance-based stock awards, the Company recognizes expense when achievement of the performance condition is probable, over the requisite service period.
The estimated grant-date fair value of the Company’s share-based awards is amortized on a straight-line basis over the awards’ service periods. Share-based compensation expense recognized was as follows (in thousands):
A summary of stock option activity and related information from January 1, 2020 through December 31, 2021 follows:
The aggregate intrinsic value of the options exercisable as of December 31, 2021 was zero, based on the difference between the Company’s closing stock price of $0.58 and the exercise price of each stock option.
The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock options at the grant date. The Black-Scholes model requires the Company to make certain estimates and assumptions, including estimating the fair value of the Company’s common stock, assumptions related to the expected price volatility of the Company’s stock, the period during which the options will be outstanding, the rate of return on risk-free investments and the expected dividend yield for the Company’s stock.
The per-share weighted average grant date fair value of the options granted to employees and directors during the years ended December 31, 2021 and 2020 was estimated at $1.25 and $1.48 per share, respectively, on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:
The weighted average valuation assumptions were determined as follows:
The Company elects to record forfeitures upon occurrence, rather than utilizing an estimate.
As of December 31, 2021, there was $6.0 million of total unrecognized compensation expense related to unvested stock options that will be recognized over the weighted average remaining period of 2.97 years.
Restricted Stock Units
RSU-related expense is recognized on a straight-line basis over the vesting period. Upon vesting, these awards may be settled on a net-exercise basis to cover any required withholding tax with the remaining amount converted into an equivalent number of shares of common stock.
There were 466,059 shares of common stock underlying vested RSUs that were withheld during the year ended December 31, 2021, based on the value of the RSU awards as determined by the Company’s closing stock price on the applicable vesting date. The shares withheld for taxes are again available for issuance under the plan.
The following is a summary of changes in the status of non-vested RSUs from January 1, 2020 through December 31, 2021:
For the years ended December 31, 2021 and 2020, the Company recorded $1.8 million and $1.1 million, respectively, in stock-based compensation expense related to RSUs, which is reflected in the statements of operations and comprehensive loss.
As of December 31, 2021, there was $6.2 million of total unrecognized compensation expense related to unvested RSUs that will be recognized over the weighted average remaining period of 3.38 years.
