Pursuant to the Company's amended and restated certificate of incorporation, the Company is authorized to issue two classes of stock; common stock and preferred stock. At December 31, 2024, the total number of shares of capital stock the Company was authorized to issue was 205,000,000 of which 200,000,000 was common stock and 5,000,000 was preferred stock. All shares of common and preferred stock have a par value of $0.001 per share.

AlmataBio Transaction

On March 27, 2024, in conjunction with the acquisition of AlmataBio, the Company issued former AlmataBio stockholders (i) 171,605 shares of the Company’s common stock, and (ii) 2,412 shares of the Company’s Series C Preferred Stock. Upon Company stockholder approval, which was obtained on August 13, 2024, and subject to beneficial ownership limitations, 2,063 shares of the Series C Preferred Stock issued to the former AlmataBio stockholders automatically converted into 2,062,930 shares of common stock. Refer to Note 3 - Asset Acquisition for more information regarding the acquisition and refer to sub-header “Series C Preferred Stock” within the “March 2024 Financing” section below for more information regarding the Series C Preferred Stock.

March 2024 Financing

On March 28, 2024, the Company closed a private placement investment in which the investors received (i) 19,946 shares of non-voting convertible Series C Preferred Stock, and (ii) warrants to purchase up to an aggregate of 11,967,526 shares of Avalo’s common stock (or a number of shares of Series C Preferred Stock convertible into the number of shares of common stock the warrant is then exercisable into), resulting in upfront gross proceeds of $115.6 million. Net proceeds were $108.1 million after deducting transaction costs of $7.5 million. The Company received an additional $69.4 million of gross proceeds upon the full exercise of the warrants in the fourth quarter of 2024. Net proceeds were $67.6 million after deducting $1.7 million of transaction costs. Both the private placement and warrant exercise transaction costs were expensed within other income (expense), net for the year ended December 31, 2024. Upon Company stockholder approval, which was obtained on August 13, 2024, and subject to beneficial ownership limitations, 6,585 shares of Series C Preferred Stock issued pursuant to the financing automatically converted into 6,585,314 shares of common stock. Additionally, the Company issued 781,259 shares of common stock and 11,186.267 shares of Series C Preferred Stock as a result of the warrant exercises in the fourth quarter of 2024. Each share of Series C Preferred Stock is convertible into 1,000 shares of common stock, subject to beneficial ownership limitations.

Warrants on common stock or Series C Preferred Stock issued in March 2024 Financing

The warrants were exercisable via gross physical settlement for $5.796933 per underlying share of common stock (or a number of shares of Series C Preferred Stock convertible into the number of shares of common stock the warrant is then exercisable into). The warrants were fully exercised in the fourth quarter of 2024. The warrants included anti-dilution protection provisions.

The Company determined that the warrants did not satisfy the conditions to be accounted for as equity instruments. As the warrants did not meet the equity contract scope exception, the Company classified the warrants as a derivative liability upon issuance. The initial measurement of the warrants at fair value exceeded the proceeds received such that the difference between the initial fair value
of the warrants and net upfront cash proceeds was recognized in the income statement as a loss. Subsequently, the warrants were carried at fair value with changes in fair value recognized in the Company’s consolidated statements of operations and comprehensive loss until exercised. Upon exercise of the warrants in the fourth quarter of 2024, the warrant liability was valued at $73.3 million. The settlement of the $73.3 million warrant liability and related share issuance proceeds of $69.4 million resulted in a $142.7 million impact to additional-paid-in-capital in the fourth quarter of 2024. The classification of the Series C Preferred Stock in permanent equity is discussed below within the “Series C Preferred Stock issued in the AlmataBio Transaction, March 2024 Financing and upon Warrant Exercises.”

The valuation of the warrants was considered under Level 3 of the fair value hierarchy due to the need to use assumptions in the valuation that are both significant to the fair value measurement and unobservable. Refer to Note 6 - Fair Value Measurements for additional information regarding the settlement and valuation of the warrant liability.

Series C Preferred Stock issued in the AlmataBio Transaction, March 2024 Financing and upon Warrant Exercises

As of December 31, 2024, the Company had 5,000,000 shares of Preferred Stock authorized, of which 34,326 have been designated as Series C Preferred Stock. As of December 31, 2024, there were 24,896 shares of Series C Preferred Stock outstanding. The Series C Preferred Stock has a par value of $0.001 per share. The Series C Preferred Stock has no voting rights, no liquidation preference, and are not redeemable. In the event of any liquidation, dissolution or winding up of the Company, holders of Series C Preferred Stock are entitled to be paid out of the assets with the Company legally available for distribution to its stockholders on an as-converted and pari-passu basis with common stock. The Series C Preferred Stock is subject to broad-based weighted average anti-dilution protection for certain issuances of common stock and securities convertible into common stock. The Series C Preferred Stock is entitled to receive dividends equal to and in the same form, and in the same manner, based on the then-current conversion ratio as dividends actually paid on shares of the common stock, when, as and if such dividends are paid on shares of the common stock.

As a result of a contract amendment in the fourth quarter of 2024, the Series C Preferred Stock met equity classification and was recognized as a component of permanent stockholders’ equity within additional paid-in-capital. Prior to the contract amendment, the Series C Preferred Stock was contingently redeemable outside the control of the Company such that the Series C Preferred Stock was recognized outside of permanent equity. As of December 31, 2024, the remaining 349 shares of Series C Preferred Stock held by the former AlmataBio stockholders, with a carrying value of $1.7 million, was reclassified into permanent equity on the consolidated balance sheet. Additionally, the 11,186.267 shares of Series C Preferred Stock issued as a result of the warrant exercises in the fourth quarter of 2024 with a carrying value of $133.0 million, were recognized as a component of permanent stockholders’ equity within additional paid in capital on the Company’s consolidated balance sheet.

No amounts were allocated to the Series C Preferred Stock issued pursuant to the March 2024 Financing because the initial fair value of the warrants exceeded gross proceeds received for the issuance of the private placement bundle that included both Series C Preferred Stock and warrants.

Series D and Series E Preferred Stock issued in the March 2024 Financing

As a condition to the March 2024 Financing, a single share of Series D Preferred Stock and a single share of Series E Preferred Stock were issued to two institutional investors that participated in the private placement. Both the Series D and the Series E Preferred Stock have a par value and liquidation preference of $0.001 per share. The Series D and Series E Preferred Stock do not have voting rights, are not entitled to dividends, and are not convertible into common stock. Each of the holders of the Series D and Series E Preferred Stock have the option to require the Company to redeem their shares at a price equal to the par value at any time. The Company retains the right to redeem the Series D and Series E Preferred Stock at a price equal to the par value if the holder owns less than a certain threshold of the Company’s outstanding common stock. Although the Series D and Series E Preferred Stock do not provide the holders with substantive economics, the Series D and Series E Preferred Stock were issued solely to allow for the institutional investors to appoint a director to the Company’s board of directors. Given the Series D and Series E Preferred Stock are redeemable at par value outside the control of the Company, they are recognized outside of permanent equity.

At-the-Market Offering Program

On May 4, 2023, the Company entered into an “at-the-market” sales agreement (the “Sales Agreement”) with Oppenheimer & Co. Inc. (“Oppenheimer”), pursuant to which the Company may sell from time to time, shares of its common stock having an aggregate offering price of up to $9,032,567 through Oppenheimer. In August 2023, the Company and Oppenheimer entered into an amendment to the Sales Agreement (the “Amended Sales Agreement”) to increase the aggregate offering amount under the Sales Agreement to $50,000,000 inclusive of shares sold prior to the amendment. During the year ended December 31, 2023, the Company sold
approximately 0.7 million shares under the ATM program for net proceeds of approximately $32.5 million. There were no sales under the ATM program during the year ended December 31, 2024.

Exchange Agreement

In May of 2023, the Company entered into an exchange agreement (the “Exchange Agreement”) with entities affiliated with Venrock Healthcare Capital Partners (“Venrock”), pursuant to which the Company exchanged an aggregate of 5,417 shares of the Company’s common stock, par value $0.001 per share, owned by Venrock, for pre-funded warrants (the “Exchanged Warrants”) to purchase an aggregate of 5,417 shares of common stock (subject to adjustment in the event of stock splits, recapitalization and other similar events affecting common stock), with an exercise price of $0.24 per share.

The Exchange Warrants were exercisable at any time, except that the Exchange Warrants would not be exercisable by Venrock if, upon giving effect immediately prior thereto, Venrock would beneficially own more than 9.99% of the total number of issued and outstanding Avalo common stock, which percentage could change at the holders’ election to any amount less than or equal to 19.99% upon 61 days’ notice to the Company. Venrock exercised the Exchanged Warrants in full in September 2023.

In accordance with ASC 505, Equity, in the second quarter of 2023, the Company recorded the retirement of the common stock exchanged as a reduction of common shares outstanding and a corresponding impact to additional paid-in-capital and accumulated deficit at the fair value of the Exchange Warrants on the issuance date. The Exchange Warrants were classified as equity in accordance with ASC 480, Distinguishing Liabilities from Equity, and the fair value of the Exchange Warrants was recorded as a credit to additional paid-in-capital and is not subject to remeasurement. The Company determined that the fair value of the Exchange Warrants is substantially similar to the fair value of the retired shares on the issuance date due to the negligible exercise price for the Exchange Warrants.

Q1 2023 Financing

On February 7, 2023, the Company closed an underwritten public offering of 15,717 shares of its common stock and warrants to purchase up to 15,717 shares of common stock, at a combined price to the public of $955 per share and warrant, resulting in net proceeds of approximately $13.7 million, after deducting the underwriting discounts and commissions and offering expenses payable by us. The warrants were immediately exercisable at an exercise price of $1,200 per share and were exercisable for one year from the issuance date, or February 2024. Prior to their expiration in February 2024, none of the warrants were exercised. Armistice, who was a significant stockholder of the Company at the time of the financing, participated in the offering by purchasing 1,875 shares of common stock and 1,875 warrants, on the same terms as all other investors. Certain affiliates of Nantahala Capital Management LLC and Point72 Asset Management, L.P., which each beneficially owned greater than 5% of the Company’s outstanding common stock at the time of the offering, participated in the offering on the same terms as all other investors.

The warrants were classified as a component of permanent stockholders’ equity within additional paid-in capital. The warrants were equity classified because they (i) were freestanding financial instruments that are legally detachable and separately exercisable from the equity instruments, (ii) were immediately exercisable, (iii) did not embody an obligation for the Company to repurchase its shares, (iv) permitted the holders to receive a fixed number of shares of common stock upon exercise, (v) were indexed to the Company’s common stock and (vi) met the equity classification criteria. In addition, such warrants did not provide any guarantee of value or return.
