| (1) | Pursuant to Rule 416(a) under the Securities Act of 1933, as amended (the “Securities Act”), this Registration Statement shall also cover any additional shares of Common Stock (“Common Stock”) of Silverback Therapeutics, Inc. (the “Registrant”) that become issuable under the Registrant’s 2016 Equity Incentive Plan, as amended (the “Prior Plan”), the Registrant’s 2020 Equity Incentive Plan (the “2020 Plan”), or the Registrant’s 2020 Employee Stock Purchase Plan (the “2020 ESPP”) by reason of any stock dividend, stock split, recapitalization or other similar transaction. |
| (2) | Represents shares of Common Stock reserved for issuance upon the exercise of outstanding stock options granted under the Prior Plan. No additional stock awards will be granted under the Prior Plan and the shares that remain available for the issuance of awards under the Prior Plan as of immediately prior to December 3, 2020 (the “Prior Plan Pool”), plus any shares subject to outstanding stock options or other stock awards granted under the Prior Plan that, on or after December 3, 2020, terminate or expire prior to exercise or settlement, are not issued because the award is settled in cash, are forfeited because of the failure to vest, or are reacquired or withheld (or not issued) to satisfy a tax withholding obligation or the purchase or exercise price (such shares, the “Prior Plan Returning Shares”), will become available for the grant of stock awards under the 2020 Plan. |
| (3) | Estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(h)(1) of the Securities Act. The proposed maximum aggregate offering price per share and proposed maximum aggregate offering price for the 3,624,721 shares of Common Stock reserved for issuance upon the exercise of outstanding stock options granted under the Prior Plan are calculated using a weighted-average exercise price of $3.45 per share. |
| (4) | Represents the sum of (1) 4,132,681 new shares, plus (2) an additional number of shares not to exceed 3,692,040 shares, which number of shares includes (i) the Prior Plan Pool and (ii) the Prior Plan Returning Shares. See footnote (2) above. The 2020 Plan provides that an additional number of shares will automatically be added to the shares authorized for issuance under the 2020 Plan on January 1st of each calendar year, from January 1, 2021 through January 1, 2030. The number of shares added each year will be equal to: (a) 5.0% of the total number of shares of capital stock of the Registrant outstanding on December 31st of the preceding calendar year; or (b) a lesser number of shares of Common Stock as the Registrant’s board of directors (the “Board”) may designate no later than December 31st of the immediately preceding year. |
| (5) | Estimated in accordance with Rule 457(h) solely for the purpose of calculating the registration fee on the basis of $21.00 per share, which is the initial public offering price per share of Common Stock set forth on the cover page of the Registrant’s prospectus dated December 3, 2020 relating to the Registrant’s initial public offering. |
| (6) | Represents 350,000 shares of Common Stock reserved for future grant under the 2020 ESPP. The 2020 ESPP provides that an additional number of shares will automatically be added to the shares authorized for issuance under the 2020 ESPP on January 1st of each calendar year, from January 1, 2021 through January 1, 2030. The number of shares of Common Stock added each year will be equal to the lesser of: (a) 1.0% of the total number of shares of capital stock outstanding on December 31st of the preceding calendar year; (b) 700,000 shares; or (c) such lesser number of shares of Common Stock as the Board may designate prior to the applicable January 1st. |
| (7) | Estimated in accordance with Rule 457(h) solely for the purpose of calculating the registration fee on the basis of $17.85 per share, which is 85% of the initial public offering price per share of Common Stock set forth on the cover page of the Registrant’s prospectus dated December 3, 2020 relating to the Registrant’s initial public offering. |

The Registrant hereby incorporates by reference into this Registration Statement the following documents previously filed by the Registrant with the Securities and Exchange Commission (“SEC”):
(a) The Registrant’s prospectus dated December 3, 2020 and filed on December 4, 2020 pursuant to Rule 424(b) under the Securities Act of 1933, as amended (the “Securities Act”), which contains audited financial statements for the Registrant’s latest fiscal year for which such statements have been filed, relating to the registration statement on Form S-1 originally filed on November 10, 2020, as amended (File No. 333-250009).
(c) The description of the Registrant’s Common Stock contained in the Registrant’s registration statement on Form 8-A filed on December 1, 2020 (File No. 001-39756) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), including any amendment or report filed for the purpose of updating such description.
All documents, reports and definitive proxy or information statements filed pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act after the date of this Registration Statement and prior to the filing of a post-effective amendment which indicates that all securities offered hereby have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference into this Registration Statement and to be a part hereof from the date of filing of such documents; provided, however, that documents, reports and definitive proxy or information statements, or portions thereof, which are furnished and not filed in accordance with the rules of the SEC shall not be deemed incorporated by reference into this Registration Statement. Any statement contained in a document incorporated or deemed to be incorporated herein by reference shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement herein or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or supersedes that statement. Any such statement so modified or superseded shall not constitute a part of this Registration Statement, except as so modified or superseded.
ITEM 4. DESCRIPTION OF SECURITIES.
Not applicable.
ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.
Not applicable.
ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
As permitted by Section 102 of the Delaware General Corporation Law, the Registrant has adopted provisions in its amended and restated certificate of incorporation and amended and restated bylaws that limit or eliminate the personal liability of its directors for a breach of their fiduciary duty of care as a director. The duty of care generally requires that, when acting on behalf of the corporation, directors exercise an informed business judgment based on all material information reasonably available to them. Consequently, a director will not be personally liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability for:
| • | any breach of the director’s duty of loyalty to the Registrant or its stockholders; |
| • | any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law; |
| • | any act related to unlawful stock repurchases, redemptions or other distributions or payment of dividends; or |
| • | any transaction from which the director derived an improper personal benefit. |
These limitations of liability do not affect the availability of equitable remedies such as injunctive relief or rescission. The Registrant’s amended and restated certificate of incorporation also authorizes the Registrant to indemnify its officers, directors and other agents to the fullest extent permitted under Delaware law.
As permitted by Section 145 of the Delaware General Corporation Law, the Registrant’s amended and restated bylaws provide that:
| • | the Registrant may indemnify its directors, officers and employees to the fullest extent permitted by the Delaware General Corporation Law, subject to limited exceptions; |
| • | the Registrant may advance expenses to its directors, officers and employees in connection with a legal proceeding to the fullest extent permitted by the Delaware General Corporation Law, subject to limited exceptions; and |
| • | the rights provided in the Registrant’s bylaws are not exclusive. |
The Registrant’s amended and restated certificate of incorporation and its amended and restated bylaws provide for the indemnification provisions described above and elsewhere herein. The Registrant has entered or will enter into, and intends to continue to enter into, separate indemnification agreements with its directors and officers that may be broader than the specific indemnification provisions contained in the Delaware General Corporation Law. These indemnification agreements generally require the Registrant, among other things, to indemnify its officers and directors against certain liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct. These indemnification agreements also generally require the Registrant to advance any expenses incurred by the directors or officers as a result of any proceeding against them as to which they could be indemnified. These indemnification provisions and the indemnification agreements may be sufficiently broad to permit indemnification of the Registrant’s officers and directors for liabilities, including reimbursement of expenses incurred, arising under the Securities Act.
The Registrant has purchased and currently intends to maintain insurance on behalf of each and every person who is one of its directors or officers against any loss arising from any claim asserted against him or her and incurred by him or her in any such capacity, subject to certain exclusions.
ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.
Not applicable.
ITEM 8. EXHIBITS.
ITEM 9. UNDERTAKINGS.
(a) The undersigned Registrant hereby undertakes:
| (1) | To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: |
| (i) | To include any prospectus required by Section 10(a)(3) of the Securities Act; |
| (ii) | To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement; |
| (iii) | To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; |
Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the Registration Statement is on Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the SEC by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement; and
| (2) | That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. |
| (3) | To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. |
| (b) | The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. |
| (c) | Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. |
Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Seattle, State of Washington, on December 4, 2020.
