EXPLANATORY NOTE
This Registration Statement on Form S-8 (this “Registration Statement”) is filed for the purposes of registering 310,000 shares of common stock, par value $0.001 per share (“Common Stock”), of Atrium Therapeutics, Inc. (the “Registrant”) that may be issued pursuant to the Atrium Therapeutics, Inc. 2026 Employment Inducement Incentive Award Plan (the “Inducement Plan”).
On April 3, 2026, the board of directors of the Registrant (the “Board”) adopted the Inducement Plan pursuant to which the Registrant reserved 310,000 shares of Common Stock to be used exclusively for grants of equity-based awards to individuals who were not previously employees or directors of the Registrant, as an inducement material to the individual’s entry into employment with the Registrant within the meaning of Rule 5635(c)(4) of the Marketplace Rules of the Nasdaq Stock Market (“Rule 5635(c)(4)”). The Inducement Plan provides for the grant of equity-based awards in the form of non-qualified stock options, stock appreciation rights, restricted stock units, restricted stock awards, unrestricted stock awards, and dividend equivalent rights. The Inducement Plan was adopted by the Board without stockholder approval pursuant to Rule 5635(c)(4).

Item 3. Incorporation of Documents by Reference.
The Registrant hereby incorporates by reference into this Registration Statement the following documents filed with the SEC:
| (a) | our effective registration statement on Form 10 (File No. 001-43008), initially filed with the SEC on December 10, 2025, as amended by Amendment No. 1 as filed with the SEC on January 30, 2026, and as further amended by Amendment No. 2 as filed with the SEC on February 17, 2026 (as so amended, the “Form 10”); |

| (c) | the description of our Common Stock under the heading “Description of Securities” in the Information Statement filed as Exhibit 99.1 to the Form 10, including any amendment or report filed for the purpose of updating such description. |
In addition, all documents (other than Current Reports furnished under Item 2.02 or Item 7.01 of Form 8-K and exhibits filed on such form that are related to such items) subsequently filed with the SEC by the Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or after the date of this Registration Statement and prior to the filing of a post-effective amendment to this Registration Statement which indicates that all securities offered herein have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference in this Registration Statement and to be a part hereof from the date of filing of such documents.
Any statement contained in a document incorporated or deemed to be incorporated by reference herein shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein
or in any subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.
Under no circumstances will any information filed under current items 2.02 or 7.01 of Form 8-K be deemed incorporated herein by reference unless such Form 8-K expressly provides to the contrary.
Item 4. Description of Securities.
Not applicable.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
Section 102(b)(7) of the General Corporation Law of the State of Delaware (“DGCL”) provides that a corporation may eliminate or limit the personal liability of a director or officer to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, as applicable, provided that such provision shall not eliminate or limit the liability of a director or officer, as applicable, (i) for any breach of the director’s or officer’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director or officer derived an improper personal benefit. Our amended and restated certificate of incorporation provides for such limitation of liability. No amendment to or repeal of such provision in our amended and restated certificate of incorporation shall apply to or have any effect on the liability or alleged liability of any director or officer for or with respect to any acts or omissions of such director or officer occurring prior to such amendment or repeal.
Section 145 of the DGCL permits a corporation to indemnify any person who is or has been a director, officer, employee or agent of the corporation or who is or has been serving as director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise at the request of the corporation, against expenses (including, but not limited to, attorneys’ fees and disbursements and amounts paid in settlement or in satisfaction of judgments or as fines or penalties) actually and reasonably incurred in connection with any action, suit or proceeding, whether civil, criminal, administrative or investigative, in which he/she may be involved by reason of the fact that he/she served or is serving in these capacities, if he/she acted in good faith and in a manner he/she reasonably believed to be in or not opposed to the best interest of the corporation and, with respect to any criminal action or proceeding, had no cause to believe his/her conduct was unlawful. In the case of an action, suit or proceeding made or brought by or in the right of the corporation to procure a judgment in its favor, the corporation shall not indemnify such person in respect of any claim, issue or matter as to which such person has been adjudged to be liable to the corporation, except for such expenses as the court may allow. Any such person who has been wholly successful on the merits or otherwise with respect to any such action, suit or proceeding or with respect to any such claim, issue or matter therein, shall be indemnified against all expenses actually and reasonably incurred in connection therewith. Our amended and restated bylaws provide for the indemnification of our directors and officers to the fullest extent permitted by law.
Our amended and restated bylaws also permit us to purchase and maintain insurance on behalf of, among others, any officer, director, employee or agent of the company against any expense, liability or loss incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the company would have the power to indemnify him or her under the DGCL. We have obtained directors’ and officers’ liability insurance.
We have entered into separate indemnification agreements with our directors and executive officers, in addition to indemnification provided for in our amended and restated certificate of incorporation and amended and restated bylaws. These agreements, among other things, provide for indemnification of our directors and executive officers to the fullest extent permitted by Delaware law, including indemnification of expenses such as attorneys’ fees, judgments, fines and settlement amounts incurred by the director or executive officer in any action or proceeding, including any action or proceeding by or in right of us, arising out of the person’s services as a director or executive officer.
Item 7. Exemption from Registration Claimed.
Not applicable.
Item 8. Exhibits.
See the Exhibit Index for a list of exhibits filed as part of this Registration Statement, which Exhibit Index is incorporated herein by reference.
Item 9. Undertakings.
(a) The 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) herein 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 (15 U.S.C. 78m or 78o(d)) that are incorporated by reference in the Registration Statement.
(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 therein, 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 therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
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.
