Rhea-AI Filing Summary

Avalo Therapeutics entered into an exchange agreement with an accredited investor to swap 4,294.675 shares of its Series C preferred stock for 4,294.675 shares of newly created Series C-1 preferred stock. The new Series C-1 is economically similar but removes a restriction so the investor’s beneficial ownership cap can be increased from 4.99% to 9.99% of common stock, subject to a Beneficial Ownership Limitation. After the exchange, 4,085.379 Series C preferred shares remain outstanding.

The company designated the Series C-1 in its charter, with each Series C-1 share initially convertible into 1,000 common shares, featuring no voting rights, parity in dividends and liquidation, and broad-based weighted average anti-dilution protection. Avalo also amended employment agreements for its CEO, CFO, CMO and Chief Business Officer, enhancing severance and change-in-control protections, including up to 18 months of salary for the CEO on certain terminations, cash severance of 1.0x–1.5x salary plus 1.0x target bonus around a change in control, COBRA premium coverage, accelerated equity vesting, and a Section 280G cutback so payments stay just below excise-tax levels if that yields a higher after-tax amount.

Insights

Avalo restructures a preferred class and enriches executive change-in-control protections.

Avalo Therapeutics creates Series C-1 preferred stock to replace 4,294.675 Series C shares for one accredited investor, lifting that holder’s potential beneficial ownership cap to 9.99%, while keeping conversions subject to a Beneficial Ownership Limitation and parity in dividends and liquidation rights.

Each Series C-1 share converts into 1,000 common shares and carries broad-based weighted average anti-dilution protection, which can amplify dilution for common shareholders if new equity is issued below prior pricing. The lack of voting rights and ownership cap partially constrain governance influence despite higher potential economic exposure.

Executive employment amendments increase certainty of payouts on terminations and change in control events through 12–18 months of salary, target bonus multiples, equity acceleration and COBRA coverage, subject to a Section 280G cutback to avoid excise taxes. These protections may modestly raise potential transaction costs in a sale scenario but clarify economics for leadership if a change in control occurs.

Beneficial Ownership Limitation financial
"conversion of the Series C-1 Preferred Stock will be subject to the Beneficial Ownership Limitation."
A beneficial ownership limitation is a rule that caps the percentage of a company’s shares an investor can be treated as owning or controlling for voting, regulatory or tax purposes. It matters to investors because it can restrict how many shares a person or group can buy or vote, affect takeover chances, and influence share liquidity and value — like a speed limit that prevents any single driver from taking over the whole road.
Change in Control financial
"In the event of a termination without Cause or For Good Reason in the period beginning three months prior to a Change in Control"
A "change in control" occurs when the ownership or management of a company shifts significantly, such as through a merger, acquisition, or sale of a large part of its assets. This change can impact how the company is run and may influence its future direction. For investors, it matters because it can affect the company's stability, strategy, and value, often signaling potential changes in investment risk or opportunity.
broad-based weighted average anti-dilution protection financial
"The Series C-1 Preferred Stock is subject to broad-based weighted average anti-dilution protection"
Certificate of Designation regulatory
"the Company filed a Certificate of Designation to its Amended and Restated Certificate of Incorporation"
A certificate of designation is a formal document that spells out the specific rights and rules attached to a particular class or series of stock, usually preferred shares. Think of it as a rulebook or menu that lists dividend terms, liquidation priority, conversion or redemption rights and any special voting protections; investors use it to judge how much income, control or downside protection those shares will provide compared with other securities.
Section 280G of the Internal Revenue Code financial
"calculated in a manner consistent with Section 280G of the Internal Revenue Code of 1986, as amended"
COBRA election financial
"upon timely COBRA election, the Company-paid portion of his or her health coverage premiums"

Item 3.02    Unregistered Sales of Equity Securities.

On June 11, 2026, Avalo Therapeutics, Inc. (the “Company”) entered into an exchange agreement (the “Exchange Agreement”) with an accredited investor to exchange 4,294.675 outstanding shares of the Company’s outstanding Series C non-voting convertible preferred stock, $0.001 par value per share (the “Series C Preferred Stock”) for 4,294.675 shares of the Company’s newly created Series C-1 non-voting convertible preferred stock, $0.001 par value per share (the “Series C-1 Preferred Stock”), such exchange, the “Exchange”. The purpose of the Exchange is to provide the investor with a class of preferred stock identical to the current Series C Preferred Stock other than the removal of the restriction applicable to the investor in the Series C Preferred Stock preventing the investor from increasing its beneficial ownership limit from 4.99% of the Company’s common stock to 9.99% of the Company’s common stock.

Upon the closing of the Exchange, 4,085.379 shares of Series C Preferred Stock will remain outstanding.

The securities described above will not be registered under the Securities Act of 1933, as amended (the “Securities Act”), or the securities law of any state, and will be exchanged in reliance on the exemptions from registration under the Securities Act afforded by Section 3(a)(9) and Section 4(a)(2) thereunder.

Item 3.03    Material Modification to rights of Security Holders.

To the extent required by Item 3.03 of this Form 8-K, the information contained in Item 3.02 of this Form 8-K is incorporated herein by reference.

Item 5.02    Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On June 12, 2026 (the “Effective Date”), the Company entered into amendments to employment agreements with Garry A. Neil, M.D., the Company’s Chief Executive Officer, Christopher Sullivan, the Company’s Chief Financial Officer, Mittie Doyle, M.D., FACR, the Company’s Chief Medical Officer and Taylor Boyd, Chief Business Officer (together, the “Employment Agreement Amendments”).

The Employment Agreement Amendments amend the provisions of the employment agreements with each of Dr. Neil, Mr. Sullivan, Dr. Doyle and Mr. Boyd that relate to potential payments and benefits in connection with certain employment terminations and a change in control. These provisions, as amended by the Employment Agreement Amendments, are summarized below:

In the event of a termination without Cause or for Good Reason: Each of Dr. Neil, Mr. Sullivan, Dr. Doyle and Mr. Boyd will be entitled to (i) twelve (12) months of his or her respective base salary as in effect immediately prior to such termination (or, in the case of Dr. Neil, eighteen (18) months), payable in substantially equal installments over the applicable severance period; (ii) if not yet paid, any unpaid bonus for the fiscal year preceding the year in which such termination occurs, based upon the achievement of Company goals as determined by the Compensation Committee of the Company’s Board of Directors, payable when such annual bonuses are paid to other executive employees of the Company; (iii) the annual bonus earned for the fiscal year in which such termination occurs, based upon the achievement of Company goals as determined by the Compensation Committee of the Company’s Board of Directors, prorated to reflect his or her completed days of employment during such year, payable when such annual bonuses are paid to other executive employees of the Company (but in no event later than March 15 of the calendar year following the year in which the termination occurs), and (iv) upon timely COBRA election, the Company-paid portion of his or her health coverage premiums during the applicable severance period.

In addition, consistent with the terms of the employment agreements prior to the Employment Agreement Amendments and solely with respect to options granted prior to the Effective Date, such options will vest in full as of such termination, and all vested options held as of the date of termination will remain exercisable thereafter for a period of twelve (12) months in the case of Dr. Neil and Mr. Sullivan and six (6) months in the case of Dr. Doyle and Mr. Boyd.

In the event of a termination without Cause or For Good Reason in the period beginning three months prior to a Change in Control and ending on the twelve month anniversary following a Change in Control): In lieu of the benefits provided above, each of Dr. Neil, Mr. Sullivan, Dr. Doyle and Mr. Boyd will be entitled to (i) the sum of (A) 1.0x of his or her respective base salary as in effect immediately prior to such termination (or, in the case of Dr. Neil, 1.5x) and (B) 1.0x of his or her annual target bonus in the year of termination; (ii) if not yet paid, any
1


unpaid bonus for the fiscal year preceding the year in which such termination occurs, based upon the achievement of Company goals as determined by the Compensation Committee of the Company’s Board of Directors, payable when such annual bonuses are paid to other executive employees of the Company; (iii) full acceleration of all outstanding and unvested time-based equity awards, which will become fully vested and exercisable or nonforfeitable as of the later of (A) the date of termination or (B) the effective date of a general release in favor of the Company, and any vested options shall remain exercisable for twelve (12) months in the case of Dr. Neil and Mr. Sullivan and six (6) months in the case of Dr. Doyle and Mr. Boyd; (iv) the annual bonus earned for the fiscal year in which such termination occurs, based upon the achievement of Company goals as determined by the Compensation Committee of the Company’s Board of Directors, prorated to reflect his or her completed days of employment during such year, payable when such annual bonuses are paid to other executive employees of the Company (but in no event later than March 15 of the calendar year following the year in which the termination occurs); and (v) upon timely COBRA election, the Company-paid portion of his or her health coverage premiums during the applicable severance period. The payments pursuant to clauses (i)-(ii) will be made promptly after the closing of the Change in Control or his or her termination, whichever is later.

Notwithstanding anything to the contrary in the employment agreement, the Company’s Fourth Amended and Restated 2016 Equity Incentive Plan (as amended), or applicable award agreement, in the event of a Change in Control, all outstanding and unvested time-based equity awards held by such executive immediately prior to the Change in Control (including any replacement, substitute or successor awards issued in respect thereof in connection with the Change in Control), to the extent not previously vested in accordance with their terms or clause (iii) above, shall become fully vested and exercisable or nonforfeitable (as applicable) upon the first anniversary of the Change in Control, provided that such executive remains continuously employed by the Company or its successor through such first anniversary.

280G Limitation: In the event any compensation, payment or distribution by the Company to each of Dr. Neil, Mr. Sullivan, Dr. Doyle and Mr. Boyd, or for their respective benefit, whether paid or payable or distributed or distributable pursuant to the terms of their respective employment agreements, as amended, or otherwise, calculated in a manner consistent with Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), and the applicable regulations thereunder (the “Aggregate Payments”), would be subject to the excise tax imposed by Section 4999 of the Code, then the Aggregate Payments shall be reduced (but not below zero) so that the sum of all of the Aggregate Payments shall be $1.00 less than the amount at which each of Dr. Neil, Mr. Sullivan, Dr. Doyle and Mr. Boyd become subject to the excise tax imposed by Section 4999 of the Code; provided that such reduction will only occur if it would result in the executive receiving a higher After Tax Amount (as defined in the respective Employment Agreement Amendment (i.e., the Aggregate Payments net of all applicable taxes, determined using the highest applicable marginal tax rates)) than what such executive would receive if the Aggregate Payments were not subject to such reduction.

The foregoing description of the Employment Agreement Amendments is qualified in its entirety by reference to the A&R Employment Agreements, copies of which are filed as Exhibit 10.1, Exhibit 10.2, Exhibit 10.3 and Exhibit 10.4 to this current report on Form 8-K and are incorporated by reference herein.

Item 5.03    Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year

On June 11, 2026, in connection with the Exchange, the Company filed a Certificate of Designation to its Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Designation”), with the Secretary of State of the State of Delaware for the purpose of designating the Series C-1 Preferred Stock.

Each share of Series C-1 Preferred Stock is initially convertible into 1,000 shares of Common Stock, subject to adjustment as described below. No fractional shares will be issued upon conversion; rather any fractional share will be rounded up to the next whole share.

In all cases, conversion of the Series C-1 Preferred Stock will be subject to the Beneficial Ownership Limitation. The “Beneficial Ownership Limitation” prevents the conversion of any portion of a holder’s Series C-1 Preferred Stock if such conversion would cause the holder, together with its affiliates, to beneficially own more than 9.99% of the outstanding shares of Common Stock after giving effect to the conversion.

Except as required by the Delaware General Corporation Law and the Certificates of Designation, the Series C-1 Preferred Stock has no voting rights. The Series C-1 Preferred Stock is entitled to receive dividends (on an as-if-converted-to-Common-Stock basis) equal to and in the same form as dividends (other than dividends in the form of Common Stock)
2


actually paid on shares of the Common Stock when, as and if declared by the Board (other than dividends in the form of Common Stock).

The Series C-1 Preferred Stock ranks in parity with the Series C Preferred Stock and Common Stock as to dividends, distributions of assets upon liquidation, dissolution or winding up of the Company, whether voluntarily or involuntarily.

The Series C-1 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 foregoing description of the Series C-1 Preferred Stock is qualified in its entirety by reference to the full text of the Series C-1 Certificate of Designation, a copy of which is attached hereto as Exhibit 3.1 and is incorporated herein by reference.

FAQ

What did Avalo Therapeutics (AVTX) change with the Series C-1 preferred stock?

Avalo created Series C-1 preferred stock and exchanged 4,294.675 existing Series C shares for 4,294.675 Series C-1 shares. Each Series C-1 share converts into 1,000 common shares, has no voting rights, and includes broad-based weighted average anti-dilution protection and a Beneficial Ownership Limitation.

How does the Beneficial Ownership Limitation work for AVTX Series C-1 preferred?

The Beneficial Ownership Limitation prevents any holder’s Series C-1 conversion from pushing its beneficial ownership above 9.99% of Avalo’s outstanding common stock. Conversions that would exceed this threshold are blocked, limiting concentration while still allowing significant economic exposure for the investor involved in the exchange.

How many Avalo Series C preferred shares remain outstanding after the exchange?

After exchanging 4,294.675 Series C preferred shares for an equal number of Series C-1 shares, Avalo states that 4,085.379 Series C preferred shares remain outstanding. These remaining Series C shares continue under their existing terms, while the exchanged shares now follow the new Series C-1 designation.

What severance benefits do Avalo executives receive upon termination without cause?

If terminated without cause or resigning for good reason, Avalo’s CEO receives 18 months of base salary, while the CFO, CMO and Chief Business Officer each receive 12 months. They also receive prior-year unpaid bonuses if earned, a prorated current-year bonus, COBRA premium coverage, and extended option exercisability.

How do Avalo’s change-in-control provisions work for top executives?

If termination without cause or for good reason occurs from three months before to 12 months after a change in control, executives receive 1.0x salary plus 1.0x target bonus, or 1.5x salary for the CEO. They also get full acceleration of time-based equity and COBRA coverage during the severance period.

What is the Section 280G excise tax limitation in Avalo’s executive agreements?

If aggregate change-in-control payments would trigger Section 4999 excise taxes, Avalo will reduce executives’ payments so total benefits are $1 below the tax threshold, but only when this yields a higher after-tax amount. This approach balances maximizing net pay with avoiding costly excise taxes on excess parachute payments.
