Common Stock

Increase in Our Authorized Number of Shares

On January 1, 2022, we amended our Certificate of Incorporation to increase the number of authorized shares of our common stock from 30,000,000 to 50,000,000. We believe 50,000,000 authorized shares of common stock better aligns our capital structure with our future needs.

ATM Offering

On August 20, 2021, we entered into the Sales Agreement with the Sales Agent under which we may issue and sell up to $30.0 million from time to time under the ATM Offering. We expect to use net proceeds from the ATM Offering over time as a source for working capital and general corporate purposes. We did not sell any shares during the three months ended March 31, 2022.

Lincoln Park Capital Fund, LLC Purchase Agreement

On March 23, 2022, we entered into the Purchase Agreement with Lincoln Park, pursuant to which Lincoln Park has committed to purchase up to $15.0 million of shares (the “Purchase Shares”) of our common stock, $0.0001 par value per share, subject to the terms and conditions in the Purchase Agreement. We issued 123,609 shares of common stock (valued at $450,000) to Lincoln Park as a commitment fee in connection with entering into the Purchase Agreement and agreed to reimburse Lincoln Park $25,000 for fees incurred in connection with the Purchase Agreement. Concurrently with entering into the Purchase Agreement, we also entered into a registration rights agreement with Lincoln Park (the “Registration Rights Agreement”), pursuant to which we agreed to take certain actions relating to the registration under the Securities Act of 1933, as amended, of the offer and sale of the shares of common stock available for issuance under the Purchase Agreement.

Beginning on March 23, 2022, we have the right to present Lincoln Park with a purchase notice (a “Regular Purchase Notice”), directing Lincoln Park to purchase up to 25,000 Purchase Shares (the “Regular Purchase Amount”) provided that the closing sale price of the common stock on the purchase date is not below a threshold price set forth in the Purchase Agreement (a “Regular Purchase”). The Regular Purchase Amount may be increased to up to 75,000 shares if the closing sale price of our common stock on the applicable purchase date equals or exceeds certain higher threshold prices set forth in the Purchase Agreement. We and Lincoln Park may mutually agree to increase the Regular Purchase Amount with respect to any Regular Purchase under the Purchase Agreement, provided that Lincoln Park’s maximum committed purchase obligation under any single Regular Purchase shall not exceed $1,250,000. The above-referenced share amount limitations and closing sale price thresholds are subject to adjustment for any reorganization, recapitalization, non-cash dividend, stock split, reverse stock split or other similar transaction as provided in the Purchase Agreement. The purchase price per share for each Regular Purchase will be based on prevailing market prices of the common stock immediately preceding the time of sale as computed in accordance with the terms set forth in the Purchase Agreement. There are no upper limits on the price per share that Lincoln Park must pay for shares of common stock under the Purchase Agreement. Lincoln Park may not assign or transfer its rights and obligations under the Purchase Agreement.

The aggregate number of shares that we can issue to Lincoln Park under the Purchase Agreement may in no case exceed 3,142,430 shares (subject to proportional adjustments for stock splits, reverse stock splits and similar events as described above), which is equal to 19.99% of the outstanding shares of common stock immediately prior to the execution of the Purchase Agreement (the “Exchange Cap”), unless (i) stockholder approval is obtained to issue shares of common stock in excess of the Exchange Cap, in which case the Exchange Cap will no longer apply, or (ii) the average price of all sales of Purchase Shares to Lincoln Park under the Purchase Agreement equals or exceeds the lower of (i) the Nasdaq official closing price immediately preceding the execution of the Purchase Agreement or (ii) the arithmetic average of the five Nasdaq official closing prices for the common stock immediately preceding the execution of the Purchase Agreement, plus an incremental amount to take into account the issuance of the commitment shares to Lincoln Park under the Purchase Agreement, such that the transactions contemplated by the Purchase Agreement are exempt from the Exchange Cap limitation under applicable Nasdaq rules. In all instances, we may not sell shares of our common stock to Lincoln Park under the Purchase Agreement if it would result in Lincoln Park beneficially owning more than 9.99% of the outstanding shares of common stock.

We may terminate the Purchase Agreement at any time, at our sole discretion, without any cost or penalty, by giving one business day notice to Lincoln Park to terminate the Purchase Agreement. Lincoln Park has covenanted not to cause or engage in any manner whatsoever, any direct or indirect short selling or hedging of the common stock.

There are no limitations on use of proceeds, financial or business covenants, restrictions on future financings (other than restrictions on our ability to enter into variable rate transactions described in the Purchase Agreement), rights of first refusal, participation rights, penalties or liquidated damages in the Purchase Agreement. We may deliver Purchase Notices under the Purchase Agreement, subject to market conditions, and in light of our capital needs from time to time and under the limitations contained in the Purchase Agreement. Any proceeds that we receive under the Purchase Agreement are expected to be used for working capital and general corporate purposes.
