Item 1.01

Entry into a Material Definitive Agreement.

Agreement and Plan of Merger

On October 31, 2023, Aileron Therapeutics, Inc., a Delaware corporation (“Aileron” or the “Company”), acquired Lung Therapeutics, Inc., a Texas corporation (“Lung”), pursuant to that certain Agreement and Plan of Merger, dated October 31, 2023 (the “Merger Agreement”), by and among Aileron, AT Merger Sub I, Inc., a Delaware corporation and a wholly owned subsidiary of Aileron (“First Merger Sub”), AT Merger Sub II, LLC, a Delaware limited liability company and wholly owned subsidiary of Aileron (“Second Merger Sub”), and Lung. Pursuant to the Merger Agreement, First Merger Sub merged with and into Lung, pursuant to which Lung was the surviving entity and became a wholly owned subsidiary of Aileron (the “First Merger”). Immediately following the First Merger, Lung merged with and into Second Merger Sub, pursuant to which Second Merger Sub was the surviving entity (the “Second Merger,” together with the First Merger, the “Merger”). The Merger is intended to qualify as a tax-free reorganization for U.S. federal income tax purposes.

Under the terms of the Merger Agreement, at the closing of the Merger, Aileron issued to the stockholders of Lung 344,566 shares of the common stock of Aileron, par value $0.001 per share (the “Common Stock”), and 20,140 shares of newly designated Series X Preferred Stock (as described below). In addition, Aileron assumed (i) all Lung stock options immediately outstanding prior to the First Merger, each becoming an option for Common Stock subject to adjustment pursuant to the terms of the Merger Agreement, and (ii) all warrants exercisable for Lung common stock immediately outstanding prior to the First Merger, each becoming a warrant to purchase Common Stock, subject to adjustment pursuant to the terms of the Merger Agreement. Immediately following the closing of the Merger, Aileron had 4,885,733 shares of Common Stock issued and outstanding.

Reference is made to the discussion of the Series X Preferred Stock in Item 5.03 of this Current Report on Form 8-K, which is incorporated into this Item 1.01 by reference.

Pursuant to the Merger Agreement, Aileron has agreed to hold a stockholders’ meeting no later than 120 days after the date on which the closing of the Merger occurs to submit the following matters to its stockholders for their consideration and approval by the holders of Common Stock (the “Requisite Stockholder Approval”): (i) the approval of the conversion of the Series X Preferred Stock issued pursuant to the Merger Agreement and the Purchase Agreement (as described below) into shares of Common Stock in accordance with Nasdaq Listing Rule 5635(a) (the “Conversion Proposal”) and (ii) if deemed necessary or appropriate by Aileron or as otherwise required by law or contract, the approval of an amendment to the certificate of incorporation of Aileron to authorize sufficient shares of Common Stock for the conversion of the Series X Preferred Stock issued pursuant to the Merger Agreement and the Purchase Agreement and/or to effectuate a reverse stock split (the “Charter Amendment Proposal”). In connection with these matters, Aileron intends to file with the U.S. Securities and Exchange Commission (the “SEC”) a proxy statement and other relevant soliciting and disclosure materials.

The Board of Directors of Aileron (the “Board”) approved the Merger Agreement and the related transactions, and the consummation of the Merger was not subject to approval of the Aileron stockholders.

The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The Merger Agreement has been included to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about Aileron or Lung. The Merger Agreement contains representations, warranties and covenants that Aileron and Lung made to each other as of specific dates. The assertions embodied in those representations, warranties and covenants were made solely for purposes of the Merger Agreement between Aileron and Lung and may be subject to important qualifications and limitations agreed to by Aileron and Lung in connection with negotiating its terms, including being qualified by confidential disclosures exchanged between the parties in connection with the execution of the Merger Agreement. The representations and warranties may be subject to a contractual standard of materiality that may be different from what may be viewed as material to investors or securityholders, or may have been used for the purpose of allocating


risk between Aileron and Lung rather than establishing matters as facts. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Aileron’s public disclosures. For the foregoing reasons, no person should rely on the representations and warranties as statements of factual information at the time they were made or otherwise.

Support Agreements

In connection with the execution of the Merger Agreement, Aileron and Lung entered into stockholder support agreements (the “Support Agreements”) with certain of Aileron’s directors and officers and its principal stockholder prior to the closing of the Merger. The Support Agreements provide that, among other things, each such director, officer or stockholder has agreed to vote or cause to be voted all of the shares of Common Stock owned by him, her or it in favor of the Conversion Proposal and any Charter Amendment Proposal at any Aileron stockholders’ meeting or any adjournment or postponement thereof, or in connection with any written consent of the stockholders of Aileron, in connection therewith.

The foregoing description of the Support Agreements does not purport to be complete and is qualified in its entirety by reference to the form of the Support Agreement, which is provided as Exhibit A to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.

Lock-up Agreements

Concurrently and in connection with the execution of the Merger Agreement, those individuals who will be serving as an officer or as a director of Aileron immediately after the Merger and the directors and officers and the majority shareholder of Lung immediately prior to the Merger entered into lock-up agreements with Aileron, pursuant to which each such director, officer or stockholder will be subject to a 180-day lockup on the sale or transfer of shares of Common Stock or any securities convertible into or exercisable or exchangeable for shares of Common Stock (including without limitation, shares of Common Stock or such other securities which may be deemed to be beneficially owned by each such director, officer or stockholder in accordance with the rules and regulations of the SEC and securities of Aileron which may be issued upon exercise of an option to purchase shares of Common Stock or a warrant to purchase shares of Common Stock) that are currently held by each such director, officer or stockholder at the closing of the Merger and hereafter owned by each such director, officer or stockholder, including those shares issued in the Merger, subject to certain customary exceptions (the “Lock-up Agreements”).

The foregoing description of the Lock-up Agreements does not purport to be complete and is qualified in its entirety by reference to the form of the Lock-up Agreement, which is provided as Exhibit B to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.

Private Placement and Stock and Warrant Purchase Agreement

Immediately following the closing of the Merger, on October 31, 2023, Aileron entered into a Stock and Warrant Purchase Agreement (the “Purchase Agreement”) with a group of accredited investors (the “Investors”) led by Bios Partners, the majority shareholder of Lung prior to the closing of the Merger, and including Nantahala Capital, as well as additional undisclosed investors. Pursuant to the Purchase Agreement, Aileron agreed to issue and sell (i) an aggregate of approximately 4,707 shares of Series X Preferred Stock, and (ii) warrants (the “Warrants”) to purchase up to an aggregate of 2,353,500 shares of Common Stock (the “Warrant Shares”), for an aggregate purchase price of approximately $18.0 million, which includes the conversion of certain convertible promissory notes in the aggregate principal amount of approximately $1.6 million issued by Lung to Bios Partners prior to the Merger at a 10% discount to the per share price of the Series X Preferred Stock (collectively, the “Financing”). The closing of the Financing is expected to occur on November 2, 2023 (the “Financing Closing Date”).

Subject to stockholder approval, each share of Series X Preferred Stock is convertible into 1,000 shares of Common Stock, as described below. The preferences, rights and limitations initially applicable to the Series X Preferred Stock are set forth in the Certificate of Designation (as described below).


Reference is made to the discussion of the Series X Preferred Stock issued in the Financing in Item 3.02 of this Current Report on Form 8-K, which is incorporated into this Item 1.01 by reference.

The foregoing summary of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the Purchase Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K.

Warrants

The exercise price of the Warrants is $4.89 per share, subject to certain price and share adjustments, including for stock splits, stock dividends, recapitalizations, subdivisions, combinations, reclassifications, noncash distributions and cash dividends. The Warrants will be exercisable any time after the later of May 2, 2024 and the date the Requisite Stockholder Approval is obtained and on or prior to May 2, 2027. Payment for Warrant Shares upon exercise of the Warrants may be (i) in cash or (ii) in the event that there is no registration statement available for the resale of Warrant Shares, by cashless exercise.

Under the terms of the Warrants, the Company shall not effect the exercise of any portion of any Warrant, and a holder shall not have the right to exercise any portion of any Warrant, to the extent that after giving effect to such exercise, the holder (together with its affiliates and any other persons acting as a group together with the holder or any of its affiliates), would beneficially own in excess of a percentage elected by the holder up to 19.99% of the number of shares of Common Stock outstanding immediately after giving effect to such exercise, as such percentage ownership is determined in accordance with the terms of the Warrants. However, any holder may, upon written notice to Aileron, increase or decrease such percentage to any other percentage not in excess of 19.99%; provided that any increase or decrease in such percentage will not be effective until 61 days after such notice is delivered to Aileron.

The foregoing summary of the Warrants does not purport to be complete and is qualified in its entirety by reference to the form of Warrant, which is filed as Exhibit 4.1 to this Current Report on Form 8-K.

Registration Rights Agreement

On the Financing Closing Date, pursuant to the Purchase Agreement, Aileron intends to enter into a Registration Rights Agreement (the “Registration Rights Agreement”) with the Investors. Pursuant to the Registration Rights Agreement, Aileron has agreed to prepare and file a resale registration statement with the SEC within 90 calendar days following the closing of the Financing (the “Filing Deadline”). Aileron will use its commercially reasonable best efforts to cause this registration statement to be declared effective by the SEC within 30 calendar days of the Filing Deadline (or within 60 calendar days in the event the SEC reviews and has comments to the registration statement).

Aileron has also agreed, among other things, to indemnify the Investors, their officers, directors, agents, partners, members, managers, stockholders, affiliates and employees under the registration statement from certain liabilities and pay all fees and expenses (excluding any underwriting discounts and selling commissions and all legal fees and expenses of legal counsel for the Investors, except for reasonable and documented fees and expenses in an amount not to exceed $30,000 of the Investors that hold a majority in interest of the registrable securities in connection with the review of the registration statement) incident to Aileron’s obligations under the Registration Rights Agreement.

The foregoing summary of the Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the form of Registration Rights Agreement, which is filed as Exhibit 10.2 to this Current Report on Form 8-K.

 

Item 2.01

Completion of Acquisition or Disposition of Assets.

On October 31, 2023, Aileron completed its acquisition of Lung. The information contained in Item 1.01 of this Current Report on Form 8-K regarding the acquisition of Lung is incorporated by reference into this Item 2.01. Aileron is currently in the process of evaluating the accounting treatment of the Merger.


Item 3.02

Unregistered Sales of Equity Securities.

The shares of Series X Preferred Stock and Warrants issued in the Financing (collectively, the “Private Placement Securities”) were offered and sold in transactions exempt from registration under the Securities Act, in reliance on Section 4(a)(2) thereof and/or Regulation D thereunder, in each case as transactions by an issuer not involving a public offering. Each of the Investors is an “accredited investor,” as defined in Regulation D, and is acquiring the Private Placement Securities for investment only and not with a view towards, or for resale in connection with, the public sale or distribution thereof, and appropriate legends have been affixed to the Private Placement Securities.

Pursuant to the Merger Agreement, Aileron issued shares of Common Stock and Series X Preferred Stock (the “Merger Shares”, and together with the Private Placement Securities, the “Securities”). The Merger Shares were issued in transactions exempt from registration under the Securities Act, in reliance on Section 4(a)(2) as a transaction not involving a public offering.

The information contained in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.02.

The Securities have not been registered under the Securities Act and such Securities may not be offered or sold in the United States absent registration or an exemption from registration under the Securities Act and any applicable state securities laws. Neither this Current Report on Form 8-K nor any of the exhibits attached hereto is an offer to sell or the solicitation of an offer to buy shares of Common Stock or any other securities of Aileron.

 

Item 4.01

Changes in Registrant’s Certifying Accountant

On October 30, 2023, Aileron dismissed its independent registered public accounting firm, PricewaterhouseCoopers LLP (“PwC”), effective immediately upon the closing of the Merger. Aileron dismissed PwC as PwC had advised Aileron that it would no longer be independent following the closing of the Merger.

The report of PwC to Aileron’s financial statements for the fiscal years ended December 31, 2022 and 2021 included in Aileron’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, did not contain an adverse opinion or a disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope or accounting principle. The report included an explanatory paragraph indicating that there was substantial doubt about Aileron’s ability to continue as a going concern.

During the years ended December 31, 2022 and 2021, and the subsequent interim period from January 1, 2023 to October 30, 2023, there were:

(i) no “disagreements” (as that term is defined in Item 303(a)(1)(iv) of Regulation S-K and the related instructions) between Aileron and PwC on any matter of accounting principles or practices, financial statement disclosure, or audit scope or procedures, which disagreements, if not resolved to PwC’s satisfaction, would have caused PwC to make reference in connection with its opinion to the subject matter of the disagreement, and

(ii) no “reportable events,” as that term is described in Item 304(a)(1)(v) of Regulation S-K and the related instructions.

Aileron has provided PwC with a copy of the disclosures made in this Item 4.01, prior to its filing and requested, in accordance with applicable practices, that PwC furnish a letter addressed to the SEC stating whether it agrees with the statements made herein. PwC furnished the letter to Aileron on October 31, 2023, a copy of which is filed as Exhibit 16.1 to this Current Report on Form 8-K.

Aileron has not yet appointed a replacement independent registered public accounting firm. Once a new independent registered public accounting firm has been appointed, Aileron will announce the appointment by filing a Current Report on Form 8-K with the SEC.


Item 5.02

Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On October 30, 2023, the Board approved the appointment of Brian Windsor, Ph.D., age 57, to President and Chief Operating Officer of Aileron, effective as of the consummation of the Merger.

Prior to becoming President and Chief Operating Officer, Dr. Windsor served, since July 2013, as President, Chief Executive Officer and a director of Lung. From September 2019 to March 2022, Dr. Windsor served as a director and the Chief Science Officer of TFF Pharmaceuticals, Inc.

Upon Dr. Windsor’s appointment as President and Chief Operating Officer of Aileron, Dr. Windsor entered into Aileron’s standard form of indemnification agreement, a copy of which was filed as Exhibit 10.12 to Amendment No. 1 to Aileron’s Registration Statement on Form S-1 (File No. 333-218474) filed with the SEC on June 19, 2017. Pursuant to the terms of this agreement, Aileron may be required, among other things, to indemnify Dr. Windsor for some expenses, including attorney’s fees, judgments, fines and settlement amounts incurred by him in any action or proceeding arising out of his service as an officer of Aileron.

There is no arrangement or understanding between Dr. Windsor and any other person pursuant to which he was elected as an officer of Aileron. Dr. Windsor has no family relationship with any of the executive officers or directors of Aileron. There are no transactions and no proposed transactions between Dr. Windsor and Aileron that would be required to be disclosed pursuant to Item 404(a) of Regulation S-K.

The foregoing summary of the Windsor Employment Agreement, the February Windsor Letter Agreement and the October Windsor Letter Agreement does not purport to be complete and is qualified in its entirety by reference to the Windsor Employment Agreement, the February Windsor Letter Agreement and the October Windsor Letter Agreement, which are filed as Exhibit 10.3, Exhibit 10.4 and Exhibit 10.5 to this Current Report on Form 8-K, respectively.

Resignation of Directors

On October 31, 2023, immediately prior to the Effective Time, Jeffrey A. Bailey, Chairman of the Board, Jodie P. Morrison and William T. McKee resigned from the Board.

In accordance with the Merger Agreement, on October 30, 2023, the Board decreased the size of the Board by one member, effective as of the Effective Time, such that the number of directors that comprised the full Board was six (6), and elected William C.

Prior to ReViral, from September 2018 to September 2019, Mr. Musso was the Chief Financial Officer and Treasurer at Peloton Therapeutics Inc., a company focused on the development of novel small molecule therapeutic candidates for the treatment of cancer. While at Peloton, Mr. Musso helped to prepare the company for an initial public offering until the company was acquired by Merck & Co. in July 2019. Prior to Peloton, from November 2014 to August 2018, Mr. Musso served as the Chief Financial Officer and Treasurer at Bellicum Pharmaceuticals, Inc., a public biotechnology company focused on discovering and developing novel, controllable cellular immunotherapies for various forms of cancer.

Item 5.03

Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On October 31, 2023, Aileron filed a Certificate of Designation of Preferences, Rights and Limitations of the Series X Preferred Stock with the Secretary of State of the State of Delaware (the “Certificate of Designation”) in connection with the Merger and the Financing referenced in Item 1.01 above. The Certificate of Designation establishes the rights of the shares of Series X Non-Voting Convertible Preferred Stock, par value $0.001 per share (the “Series X Preferred Stock”), which is intended to have economic rights equivalent to the Common Stock, but has only limited voting rights.

Holders of Series X Preferred Stock are entitled to receive dividends on shares of Series X Preferred Stock equal, on an as-if-converted-to-Common-Stock basis, and in the same form as dividends actually paid on shares of the Common Stock. Subject to stockholder approval of the Conversion Proposal, the Series X Preferred Stock is convertible into Common Stock at rate of 1,000 shares of Common Stock for every one share of Series X Preferred Stock that is converted. Except as otherwise required by law, the Series X Preferred Stock does not have voting rights. However, as long as any shares of Series X Preferred Stock are outstanding, Aileron will not, without the affirmative vote of the holders of a majority of the then outstanding shares of the Series X Preferred Stock, (i) alter or change adversely the powers, preferences or rights given to the Series X Preferred Stock or alter or amend the Certificate of Designation, amend or repeal any provision of, or add any provision to, the Certificate of Incorporation or by-laws of the Company, or file any articles of amendment, certificate of designations, preferences, limitations and relative rights of any series of preferred stock, if such action would adversely alter or change the preferences, rights, privileges or powers of, or restrictions provided for the benefit of the Series X Preferred Stock, (ii) issue further shares of Series X Preferred Stock or increase or decrease (other than by conversion) the number of authorized shares of Series X Preferred Stock, or (iii) enter into any agreement with respect to any of the foregoing. Additionally, the approval of the holders of a majority of the Series X Preferred Stock is required for certain change of control transactions, provided that this approval right will terminate upon stockholder approval of the Conversion Proposal. The Series X Preferred Stock does not have a preference upon any liquidation, dissolution or winding-up of Aileron.

Following stockholder approval of the Conversion Proposal, (i) effective as of 5:00 p.m. (Eastern time) on the fourth business day after the date on which such stockholder approval is received, each share of Series X Preferred Stock then outstanding automatically converts into 1,000 shares of Common Stock, and (ii) at any time thereafter at the option of the holder thereof, into 1,000 shares of Common Stock, in the case of each of (i) and (ii) subject to certain beneficial ownership limitations, including that a holder of Series X Preferred Stock is prohibited from converting shares of Series X Preferred Stock into shares of Common Stock if, as a result of such conversion, such holder (together with its affiliates and any other persons acting as a group together with the holder or any of its affiliates) would beneficially own more than a specified percentage (to be initially set at 19.99% and thereafter adjusted by the holder to a number not to exceed 19.99%) of the total number of shares of Common Stock issued and outstanding immediately after giving effect to such conversion.


The foregoing description of the Series X Preferred Stock does not purport to be complete and is qualified in its entirety by reference to the Certificate of Designation, a copy of which is filed as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated herein by reference.

 

Item 7.01

Item 8.01

Other Events.

As of September 30, 2023 on a pro forma basis to give effect to the receipt of gross proceeds of the Financing, Aileron and Lung’s combined cash and cash equivalents was approximately $29.0 million. Based on Aileron’s current operating plan, Aileron estimates that these cash resources will enable Aileron to fund its operating expenses and capital expenditure requirements as currently planned into the fourth quarter of 2024. Aileron has based this estimate on assumptions that may provide to be wrong, and Aileron could use its available capital resources sooner than it currently expects.
