Series A Convertible Preferred Stock Series A Convertible Preferred Stock
On April 1, 2024, the Company entered into an Investment Agreement (the “Investment Agreement”) with certain affiliates of Perceptive Advisors LLC (“Perceptive”) and certain other investors (each, an “Investor” and collectively, the “Investors”), relating to the issuance and sale of 150,000 shares of a new series of the Company’s Series A Convertible
Preferred Stock, par value $0.001 per share, titled the “Series A Convertible Preferred Stock” (the “Convertible Preferred Stock”), for an aggregate purchase price of $147.8 million, net of $2.3 million of issuance costs, or $1,000 per share (the “Issuance”). The Issuance closed on April 15, 2024.
The Company determined the obligation to issue 150,000 shares of Convertible Preferred Stock to Perceptive and Investors in the future at a set price represented a forward contract which was required to be accounted for at fair value. The fair value of the forward contract was measured as the difference between the fair value of the Convertible Preferred Stock, as determined using a binomial lattice valuation model, and the consideration payable to the Company. The assumptions used in the binomial lattice model include: (1) the Company’s common stock price on the issuance and settlement dates; (2) the Conversion Price as of $48.00 as per the Agreement; (3) a 20-year term to maturity; (4) an estimate of the Company’s credit risk-adjusted discount rate; and (5) volatility. The fair value of the forward contract upon issuance was determined to be $0. Upon closing, the value of the forward contract was determined to be $8.9 million and the fair value of the Convertible Preferred Stock was determined to be $141.1 million.
The Company classifies its Convertible Preferred Stock outside of stockholders’ equity as the redemption of such shares is outside the Company’s control. The Company did not adjust the carrying values of the Convertible Preferred Stock to redemption value as the shares are not probable of becoming redeemable as of March 31, 2026.
On December 4, 2025, and in accordance with the terms described below, a holder of the Company's Series A Convertible Preferred Stock exercised their right to convert 17,500 shares of Series A Convertible Preferred Stock to common shares. Each of the 17,500 shares of Series A Convertible Preferred Stock converted to 20.8333 shares of common stock, resulting in a total of 364,582 shares of common stock. The Company reclassified the carrying value of the converted shares of $17.2 million from Series A convertible Preferred Stock to common stock and additional paid in capital, for this non-cash financing event.

On January 26, 2026, and in accordance with the terms described below, the same holder exercised its right to convert another 17,500 shares of Series A Convertible Preferred Stock to common shares. Each of the 17,500 preferred shares converted to 20.8333 shares of common stock, resulting in a total of 364,582 shares of common stock. The Company reclassified the carrying value of the converted shares of $17.4 million from Series A convertible Preferred Stock to common stock and additional paid in capital, for this non-cash financing event.

The Convertible Preferred Stock has the following rights and privileges:
Liquidation:
The Convertible Preferred Stock will rank senior to the Company’s common stock with respect to the distribution of assets upon the Company’s liquidation, dissolution or winding up.
Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary (“Liquidation”), each holder of Convertible Preferred Stock shall be entitled to receive payment for the greater of (i) 1.75 multiplied by the sum of the Liquidation Preference (i.e., Initial Liquidation Preference of $1,000 per share plus Paid-in-Kind (“PIK”) Dividends) plus unpaid Regular Dividends (to the extent such accumulated and unpaid Regular Dividends are not included in such Liquidation Preference) or (ii) the amount such holder would have received if the Convertible Preferred Stock were fully converted to common stock. If the assets available for distribution are not sufficient to pay the holders of the Convertible Preferred Stock pursuant to the preceding sentence, the assets will be distributed ratably to the holders of the Convertible Preferred Stock.
Voting:
Holders of the Convertible Preferred Stock have the right to vote with the holders of common stock on each matter submitted for a vote on an as-converted basis, subject to the terms of the Convertible Preferred Stock as specified in the Amended and Restated Certificate of Designations.
The holders of the Convertible Preferred Stock shall also have certain protective voting rights. Specifically, as long as the Convertible Preferred Stock are outstanding, each of the following events require at least a two thirds affirmative vote of the Convertible Preferred Stock holders: (a) any amendment or modification of the Certificate of Incorporation to authorize or create, or to increase the authorized number of shares of, any class or series of Dividend Parity Stock, Liquidation Parity Stock, Dividend Senior Stock or Liquidation Senior Stock, (b) any amendment,
modification, repeal or waiver of any provision of the Certificate of Incorporation or the Amended and Restated Certificate of Designations that adversely affects the rights, preferences, privileges or powers of the Convertible Preferred Stock, (c) increase or decrease the number of authorized shares of Convertible Preferred Stock or issue additional shares of Convertible Preferred Stock, (d) the Company’s consolidation or combination with, or merger with or into, another Person, or any binding or statutory share exchange or involving the Convertible Preferred Stock, in each case unless: (i) the Convertible Preferred Stock either (x) remains outstanding after such consolidation, combination, merger, share exchange or reclassification; or (y) is converted or reclassified into, or is exchanged for, or represents solely the right to receive, preference securities of the continuing, resulting or surviving Person of such consolidation, combination, merger, share exchange or reclassification, or the parent thereof; (ii) the Convertible Preferred Stock that remains outstanding or such preference securities, as applicable, have rights, preferences and voting powers that, taken as a whole, are not materially less favorable to the Holders or the holders thereof, as applicable, than the rights, preferences and voting powers, taken as a whole, of the Convertible Preferred Stock immediately before the consummation of such consolidation, combination, merger, share exchange or reclassification; and (iii) the issuer of the Convertible Preferred Stock that remains outstanding or such preference securities, as applicable, is a corporation duly organized and existing under the laws of the United States of America, any State thereof or the District of Columbia that, if not the Company, will succeed to the Company under the Amended and Restated Certificate of Designations and the Convertible Preferred Stock.
Redemption:
The Company has the right to redeem all Convertible Preferred Stock after the Redemption Trigger Date, which is the fifth anniversary of the Initial Issue Date of April 15, 2024. The amount payable on the redemption date is equal to the Liquidation Preference (i.e., Initial Liquidation Preference of $1,000 per share plus PIK Dividends) plus any unpaid Regular Dividends (to the extent such accumulated and unpaid Regular Dividends are not included in such Liquidation Preference).
If a change of control occurs, each holder shall have the right to require the Company to repurchase all, or any whole number of shares that is less than all, of the holder’s Convertible Preferred Stock at an amount equal to 1.75 multiplied by the sum of the Liquidation Preference (i.e., Initial Liquidation Preference of $1,000 per share plus PIK Dividends) plus any unpaid Regular Dividends (to the extent such accumulated and unpaid Regular Dividends are not included in such Liquidation Preference). As of March 31, 2026, the Company did not adjust the carrying value of the Convertible Preferred Stock to its redemption value, since a change of control was determined to be not probable.
Dividends:
After the second anniversary, dividends on the Convertible Preferred Stock accrue quarterly, at a 6% annual rate, and if not paid out in cash before the quarter end, will become PIK Dividends and added to the liquidation preference, or original issue price plus PIK Dividends. Since dividends do not commence until the second anniversary of the Issuance, the Convertible Preferred Stock is considered increasing rate preferred stock. Accordingly, the Company accretes the dividends, using the effective interest method, from Issuance to the first contractual call date, April 15, 2029. The Company accrued dividends of $1.1 million and $1.3 million for the three months ended March 31, 2026 and March 31, 2025, as a reduction to Additional Paid-In Capital and an increase to the carrying value of Convertible Preferred Stock. The carrying value of Convertible Preferred Stock as of March 31, 2026 and December 31, 2025 is $114.7 million and $131.0 million, respectively.
Conversions:
Holders of Convertible Preferred Stock have the option to convert any number of whole shares at any time. The conversion is based on the sum of the Liquidation Preference plus unpaid Dividends divided by the $48.00 Conversion Price. Given the Initial Liquidation Preference of $1,000, each share of Convertible Preferred Stock would be convertible into 20.8333 shares of common stock, prior to any adjustments such as PIK Dividends, unpaid Dividends, stock splits, or voluntary conversion rate increases. Upon conversion, cash will be paid in lieu of any fractional share of common stock. However, based on certain restrictions on the conversion of the Convertible Preferred Stock specified in the Amended and Restated Certificate of Designations, a holder of Convertible Preferred Stock is not entitled to effect a conversion of any portion of its shares of Convertible Preferred Stock, or to vote in its capacity as a holder of shares of Convertible Preferred Stock with respect to matters submitted to holders of the common stock if, after giving effect to such conversion, that holder would beneficially own in excess of 4.99%, in the case of one holder, or 9.99%, in the case of the other holder, of the number of shares of common stock outstanding immediately after giving effect to such exercise.
On May 7, 2024, the Company filed an Amended and Restated Certificate of Designations in respect of the Convertible Preferred Stock containing certain technical amendments to the terms of the Convertible Preferred Stock. The amendments contained in the Amended and Restated Certificate of Designations (x) limited the voting rights of the Convertible Preferred Stock to 24.9438 shares of the Company’s common stock per $1,000 liquidation preference of Convertible Preferred Stock and (y) eliminated a 1% step up in the interest rate that otherwise would have applied in the unlikely event that the Company was required to obtain and failed to obtain stockholder approval for certain conversion shares underlying the Convertible Preferred Stock.
On February 26, 2026, the Company filed with the Securities Exchange Commission (the “SEC”) a registration statement on Form S-3ASR containing a prospectus covering the resale from time to time by the Investors of up to an aggregate of 2,395,831 shares of common stock, to satisfy registration rights that the Company granted to such stockholders in connection with the Issuance.

The Company has 10,000,000 shares of Preferred Stock authorized, of which 150,000 shares are designated for the Series A Convertible Preferred Stock.
