New heading “Risks Related to the Merger”

New heading “Failure to complete, or delays in completing, the proposed Merger with Candid could materially and adversely affect our results of operations, business, financial results and/or stock price.”

New heading “We are substantially dependent on our remaining employees to facilitate the consummation of the Merger.”

New heading “The Exchange Ratio will not be adjusted based on the market price of our common stock, so the consideration at the closing of the Merger may have a greater or lesser value than at the time the Merger Agreement was signed.”

New heading “The Merger may be completed even though a material adverse effect may result from the announcement of the Merger, industry-wide changes and/or other causes.”

New heading “Some of our executive officers and directors have interests in the Merger that are different from our stockholders and that may influence them to support or approve the Merger without regard to the interests of our stockholders.”

New heading “Our stockholders may not realize a benefit from the Merger commensurate with the ownership dilution they will experience in connection with the Merger.”

New heading “Our equityholders will have a reduced ownership and voting interest in, and will exercise less influence over the management of, the combined company following the completion of the Merger as compared to their current ownership and voting interests in the respective companies.”

New heading “Lawsuits may be filed against us and the members of our board of directors arising out of the proposed Merger, which may delay or prevent the proposed Merger.”

New heading “During the pendency of the Merger Agreement, we may not be able to enter into a business combination with another party at a favorable price because of restrictions in the Merger Agreement, which could adversely affect their respective businesses.”

New heading “Certain provisions of the Merger Agreement may discourage third parties from submitting competing proposals, including proposals that may be superior to the arrangements contemplated by the Merger Agreement.”

New heading “If the Merger does not qualify as a reorganization under the Code, U.S. holders of our Common Stock may be taxed on the full amount of the consideration received in the Merger.”

New heading “We or Candid may waive one or more of the conditions to the Merger without recirculation of the related proxy statement/prospectus or resoliciting stockholder approval.”

New heading “Our winddown of our historical operations, the sale of assets, the suspension of development activities and the proposed Merger, resulting in the conversion of Candid into a public company, will make us subject to the SEC requirements applicable to reporting shell company business combinations. As a result, the combined company will be subject to more stringent reporting requirements, offering limitations and resale restrictions.”

New heading “Our stockholders may not receive any payment on the CVRs and the CVRs may otherwise expire valueless.”

New heading “The tax treatment of the CVRs is uncertain.”

New heading “If the Merger is not completed, our stock price may decline significantly.”

New heading “If we do not complete the Merger, we may face substantial competition for attractive counterparties for any proposed strategic transactions.”

New heading “If we do not successfully consummate the Merger or another strategic transaction, our board of directors may decide to pursue a dissolution and liquidation of our company. In such an event, the amount of cash available for distribution to our stockholders will depend heavily on the timing of such liquidation as well as the amount of cash that will need to be reserved for commitments and contingent liabilities, as to which we can give you no assurance.”

New heading “Our failure to meet the listing standards of the Nasdaq could result in the delisting of our common stock. Delisting could adversely affect the liquidity of our common stock and the market price of our common stock could decrease, and our ability to obtain sufficient additional capital to fund our operations and to continue to operate as a going concern would be substantially impaired.”

Removed heading “The FDA, EMA or other comparable foreign regulatory authorities, could require the clearance or approval of an in vitro diagnostic or companion diagnostic device as a condition of approval for any product candidate that requires or would commercially benefit from such tests, including RLYB212. Failure to successfully validate, develop and obtain regulatory clearance or approval for companion diagnostics on a timely basis or at all could harm our drug development strategy.”

Removed heading “Although RLYB212 has received FDA designation as a rare pediatric disease drug product, any marketing application we submit for RLYB212 may not qualify for issuance of a rare pediatric disease priority review voucher.”

Removed heading “If the FDA, EMA or other comparable foreign regulatory authorities approve generic versions of any of our small molecule investigational products that receive marketing approval, or such authorities do not grant our products appropriate periods of exclusivity before approving generic versions of those products, the sales of our products, if approved, could be adversely affected.”

Removed heading “We expect to expand our development, regulatory, and sales and marketing capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.”

Removed heading “Our common stock may be delisted from The Nasdaq Global Select Market, which could harm the trading price of our common stock, the liquidity of our common stock, and our ability to raise additional capital.”

Paragraph as it now reads, with added and removed wording marked:

In the United States, the CCPA imposes many obligations for the collection, processing, and sharing of personal information of California residents. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. Because we have not yet generated revenue and do not meet the CCPA’s other jurisdictional tests, we do not yet meet the applicable threshold for the CCPA to apply to our business. If our business becomes subject to CCPA in the future, it could increase our compliance costs and potential liability. Similar laws have been proposed or passed in more than half of the states in the U.S. and in the U.S. Congress. In addition, Washington state enacted the My Health, My Data Act, a health-focused consumer privacy law, which took effect in March 2024. This law imposes obligations related to the collection and sharing of certain health-related information that is not subject to HIPAA and that does not fall within certain other exceptions in the law. Other states have enacted, or are in the process of enacting, similar health-focused consumer privacy laws. Also of note, in June 2024, the Protecting Americans’ Data from Foreign Adversaries Act of 2024 took effect. This law prohibits data brokers from making available certain personally identifiable sensitive data of U.S. individuals to “foreign adversary” countries, such as the PRC, and entities controlled by such countries. Additionally, in January 2025, the U.S. Department of Justice published a final rule implementing President Biden’s Executive Order 14117, “Preventing Access to Americans’ Bulk Sensitive Personal Data and United States Government-Related Data by Countries of Concern.” This final rule prohibits certain data brokerage transactions and transactions involving certain bulk human ‘omic data, including human genomic data and biospecimens from which such data can be derived, with restricted persons and jurisdictions, such as the PRC. The final rule also places restrictions on certain vendor, employment and investment agreements with such jurisdictions. Most provisions of the final rule are scheduled to take effect in April 2025. These restrictions may affect our ability to engage in collaborations or license agreements with entities in restricted countries or with a nexus to such countries going forward. Furthermore, all fifty U.S. states, the District of Columbia, Puerto Rico, and other U.S. territories have enacted data breach notification laws that require, among other things, notifications to state governments and/or the affected individuals in the event of a data breach,breach. whichSuch laws differ from one anotheranother, and may impose significant compliance burden.

Risks Related to the Merger

Added

Failure to complete, or delays in completing, the proposed Merger with Candid could materially and adversely affect our results of operations, business, financial results and/or stock price.

Added

Any failure to satisfy a required condition to closing may prevent, delay or otherwise materially and adversely affect the completion of the Merger, which could materially and adversely affect our results of operations, business, financial results and/or stock price. We cannot predict with certainty whether or when any of the required closing conditions will be satisfied or if another uncertainty may arise and cannot assure you that the proposed Merger will be successfully consummated or that we will be able to successfully consummate the proposed Merger as currently contemplated under the Merger Agreement or at all.

Added

Even if certain of the proposals in the Merger Agreement are approved by our stockholders, specified conditions must be satisfied or, to the extent permitted by applicable law, waived to complete the Merger. We cannot assure you that all of the conditions will be satisfied or waived.

Added

Risks related to the failure to consummate, or delay in consummating, the proposed Merger with Candid include, but are not limited to, the following:

Added

•we would not realize any or all of the potential benefits of the Merger, which could have a negative effect on our results of operations, business or stock price;

Added

•under some circumstances, we may be required to pay a termination fee to Candid of $1.425 million, with expense reimbursement of up to $500,000 credited against the payment of any such termination fee;

Added

•we would remain liable for significant transaction costs, including legal, accounting, financial advisory and other costs relating to the Merger regardless of whether the Merger is consummated;

Added

•the trading price of our common stock may decline to the extent that the current market price for our common stock reflects a market assumption that the Merger will be completed;

Added

•the attention of our management and employees may have been diverted to the Merger rather than to our historical operations and the pursuit of other opportunities that could have been beneficial to us;

Added

•we could be subject to litigation related to any failure to complete the Merger;

Added

•we could potentially lose key personnel during the pendency of the Merger; and

Added

•under the Merger Agreement, we are subject to certain customary restrictions on the conduct of our business prior to completing the Merger, which restrictions could adversely affect our ability to conduct our business as we otherwise would have done if we were not subject to these restrictions.

Added

The occurrence of any of these events individually or in combination could materially and adversely affect our results of operations, business, and our common stock price, and we may lose some or all the intended benefits of the Merger.

Added

We are substantially dependent on our remaining employees to facilitate the consummation of the Merger.

Added

Our ability to consummate a strategic transaction depends upon our ability to retain our remaining employees required to consummate such a transaction, the loss of whose services may adversely impact the ability to consummate such transaction. As of December 31, 2025, we had only 14 full-time employees. Our ability to successfully complete the Merger depends in large part on our ability to retain key personnel that are necessary to maintain our operations between now and the Effective Time. Despite our efforts to retain these employees, one or more may terminate their employment with us on short notice. Our cash conservation activities may yield other unintended consequences, such as reduced employee morale, which may cause remaining employees to seek alternative employment. The loss of the services of certain employees could potentially harm our ability to consummate the Merger, to run our day-to-day business operations, as well as to fulfill our reporting obligations as a public company.

Added

The Exchange Ratio will not be adjusted based on the market price of our common stock, so the consideration at the closing of the Merger may have a greater or lesser value than at the time the Merger Agreement was signed.

Added

The Exchange Ratio will not change based on changes in the trading price of our common stock. Therefore, if before the completion of the Merger, the market price of our common stock increases from the market price on the date of the Merger Agreement, Candid stockholders could then receive merger consideration with substantially higher value for their shares of Candid common stock than the parties had negotiated when they established the Exchange Ratio. The Merger Agreement does not include a price-based termination right. Immediately after the Merger, our securityholders as of immediately prior to the Merger are expected to own approximately 3.65% of the outstanding shares of the combined company and former Candid securityholders, including purchasers in the Concurrent Financing, are expected to own approximately 96.35% of the outstanding shares of the combined company, subject to certain assumptions, including, but not limited to, (a) a valuation of us equal to $47.5 million, based on certain assumptions, including our net cash as of the closing date of the Merger being equal to $37.5 million, (b) a valuation for Candid equal to $750.0 million and (c) Candid issuing approximately $505.5 million of Candid Common Stock in the Concurrent Financing described in the related proxy statement/prospectus.

Added

The Merger may be completed even though a material adverse effect may result from the announcement of the Merger, industry-wide changes and/or other causes.

Added

In general, either we or Candid can refuse to complete the Merger if there is a Rallybio Material Adverse Effect (as defined in the Merger Agreement) or a Company Material Adverse Effect (as defined in the Merger Agreement), as applicable, between March 1, 2026, the date of the Merger Agreement, and the closing of the Merger. However, certain types of changes do not permit either party to refuse to complete the Merger, even if such change could be said to have a material adverse effect on us or Candid, including:

Added

•general business, political or economic conditions generally affecting the industry in which we or Candid operate, including with respect to the imposition of, or adjustments to, tariffs or other trade restrictions;

Added

•acts of war, the outbreak or escalation of armed hostilities, acts of terrorism, earthquakes, wildfires, hurricanes or other natural disasters, health emergencies, including pandemics and related or associated epidemics, disease outbreaks or quarantine restrictions;

Added

•changes in financial, banking or securities markets;

Added

•any change in the stock price or trading volume of our common stock (it being understood, however, that any effect causing or contributing to any change in stock price or trading volume of our common stock may be taken into account in determining whether a material adverse effect with respect to us has occurred, unless such effects are otherwise excepted from the definition of Rallybio Material Adverse Effect);

Added

•any failure by us to meet internal or analysts’ expectations or projections or the results of our operations (it being understood, however, that any effect causing or contributing to the failure of us to meet internal or analysts’ expectations or projections or the results of our operations may be taken into account in determining whether a material adverse effect with respect to us has occurred, unless such effects are otherwise excepted from the definition of Rallybio Material Adverse Effect);

Added

•any change in, or any compliance with or action taken for the purpose of complying with, any applicable law or GAAP (or interpretations of any applicable law or GAAP);

Added

•the announcement of the Merger Agreement or the pendency of the Contemplated Transactions; or

Added

•the taking of any action required to be taken by the Merger Agreement.

Added

If a material adverse change occurs with respect to either party or both parties and we and Candid still complete the Merger, the stock price of the combined company following the closing of the Merger may suffer and may reduce the value of the Merger to our stockholders.

Added

Some of our executive officers and directors have interests in the Merger that are different from our stockholders and that may influence them to support or approve the Merger without regard to the interests of our stockholders.

Added

Certain of our executive officers and directors are parties to arrangements that provide them with interests in the Merger that are different from our stockholders, including severance benefits, the acceleration of equity award vesting and continued indemnification.

Added

In addition, Robert Hopfner, a current member of our board, is affiliated with an investment fund participating in the Concurrent Financing.

Added

Our board of directors was aware of and considered these interests, among other matters, in reaching its determination (i) that the terms of the Merger Agreement and the Merger and the other Contemplated Transactions are fair to, advisable and in the best interest of us and our stockholders and (ii) to approve and declare advisable the Merger Agreement and the Contemplated Transactions, including the Merger and the issuance of shares of our common stock to the stockholders of Candid pursuant to the Merger Agreement. These interests, among other factors, may have influenced the directors and executive officers to support or approve the Merger.

Added

Our stockholders may not realize a benefit from the Merger commensurate with the ownership dilution they will experience in connection with the Merger.

Added

If the combined company is unable to realize the full strategic and financial benefits currently anticipated from the Merger, our stockholders will have experienced substantial dilution of their ownership interests without receiving any commensurate benefit, or only receiving part of the commensurate benefit to the extent the combined company is able to realize only part of the strategic and financial benefits currently anticipated from the Merger.

Added

Our equityholders will have a reduced ownership and voting interest in, and will exercise less influence over the management of, the combined company following the completion of the Merger as compared to their current ownership and voting interests in the respective companies.

Added

After the completion of the Merger, our current stockholders will own a smaller percentage of the combined company than their ownership of their respective companies prior to the Merger. Immediately after the Merger, our securityholders as of immediately prior to the Merger are expected to own approximately 3.65% of the outstanding shares of the combined company and former Candid securityholders, including purchasers in the Concurrent Financing, are expected to own approximately 96.35% of the outstanding shares of the combined company, subject to certain assumptions, including, but not limited to, (a) our valuation equal to $47.5 million, based on certain assumptions, including our net cash as of the closing date of the Merger being equal to $37.5 million, (b) a valuation for Candid equal to $750.0 million and (c) Candid issuing approximately $505.5 million of Candid Common Stock in the Concurrent Financing.

Added

Lawsuits may be filed against us and the members of our board of directors arising out of the proposed Merger, which may delay or prevent the proposed Merger.

Added

Putative stockholder complaints, including stockholder class action complaints, and other complaints may be filed against us, our board of directors, Candid, the Candid Board of directors and others in connection with the transactions contemplated by the Merger Agreement. The outcome of litigation is uncertain, and we may not be successful in defending against any such future claims. Lawsuits that may be filed against us, our board of directors, Candid, or the Candid board of directors could delay or prevent the Merger, divert the attention of our management and employees from our day-to-day business and otherwise adversely affect our financial condition.

Added

During the pendency of the Merger Agreement, we may not be able to enter into a business combination with another party at a favorable price because of restrictions in the Merger Agreement, which could adversely affect their respective businesses.

Added

Covenants in the Merger Agreement impede our ability to make acquisitions or complete other mergers, sales of assets or other business combinations pending completion of the Merger. As a result, if the Merger is not completed, the parties may be at a disadvantage to their competitors during that period. In addition, while the Merger Agreement is in effect, each party is generally prohibited from soliciting, initiating, knowingly encouraging or entering into specified extraordinary transactions, such as a merger, sale of assets or other business combination, with any third party, subject to specified exceptions, even if any such transaction could be favorable to such party’s stockholders or stockholders, as applicable.

Added

Certain provisions of the Merger Agreement may discourage third parties from submitting competing proposals, including proposals that may be superior to the arrangements contemplated by the Merger Agreement.

Added

The terms of the Merger Agreement prohibit each of us and Candid from soliciting competing proposals or cooperating with persons making unsolicited takeover proposals, except in certain limited circumstances. With respect to us, the board of directors may respond to an unsolicited competing proposal if it determines in good faith, after consultation with its outside financial advisor and outside legal counsel, that the unsolicited competing proposal constitutes, or is reasonably likely to result in, a superior competing proposal and, after consultation with its outside legal counsel, that failure to take such action would be inconsistent with the fiduciary duties of our board of directors. With respect to Candid, following receipt of a bona fide acquisition proposal by any person that the Candid Board has determined is reasonably likely to result in a superior competing proposal, Candid may solicit acquisition proposals and furnish information to, and enter into discussions with, any person (including persons not making such proposal) if the Candid Board concludes in good faith, after consultation with its outside legal counsel and financial advisor, that failure to take such action would be inconsistent with the fiduciary duties of the Candid Board.

Added

In certain circumstances, and subject to compliance with the Merger Agreement, our board of directors or the Candid Board may change its recommendation to its respective stockholders if it determines such recommendation change is required to avoid a breach of its fiduciary duties. Additionally, subject to compliance with the procedures set forth in the Merger Agreement, including paying the applicable termination fee, Candid may terminate the Merger Agreement in order to enter into an agreement with respect to a Superior Offer (as defined in the Merger Agreement).

Added

Upon termination of the Merger Agreement in certain circumstances, a termination fee of $1.425 million may be payable by us to Candid if (i)(a) the Merger Agreement is terminated because the Merger has not been consummated by the End Date or we (1) fail to obtain the requisite stockholder approval of the Rallybio Stockholder Matters or (2) breach the Merger Agreement, (b) an alternative acquisition proposal was announced or disclosed prior to such termination, and (c) within 12 months of the termination of the Merger Agreement, we enter into a definitive agreement with respect to an alternative transaction, (ii) we fail to include our board recommendation in the related proxy statement/prospectus, or (iii) our board of directors changes or withdraws its recommendation in favor of the Merger or approves an alternative transaction, or willfully and intentionally breaches its non-solicitation or certain other obligations under the Merger Agreement.

Added

Both we and Candid have also each agreed to reimburse the other party for up to $500,000 for third-party expenses, as applicable, if the Merger Agreement is terminated in certain circumstances.

Added

These termination fees and expense reimbursement provisions may discourage third parties from submitting competing proposals to us or Candid or their respective stockholders and may cause our board of directors or the Candid board, as the case may be, to be less inclined to recommend a competing proposal.

Added

If the Merger does not qualify as a reorganization under the Code, U.S. holders of our Common Stock may be taxed on the full amount of the consideration received in the Merger.

Added

Each of we and Candid intend that the Merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code. Assuming the Merger so qualifies, no gain will be recognized by U.S. holders of Candid shares will not recognize gain or loss for U.S. federal income tax purposes upon the receipt of shares of our common stock in exchange for Candid shares in the Merger. It is not, however, a condition to the parties’ obligation to complete the transactions that the Merger so qualifies. None of the parties to the Merger Agreement have sought or intend to seek any ruling from the Internal Revenue Service (“IRS”) regarding the qualification of the Merger as a reorganization within the meaning of Section 368(a) of the Code. If the Merger does not qualify for the U.S. federal income tax treatment described herein, U.S. holders of Candid shares may be taxed on any gain realized up to the full fair market value of any our Common Stock received in the Merger.

Added

We or Candid may waive one or more of the conditions to the Merger without recirculation of the related proxy statement/prospectus or resoliciting stockholder approval.

Added

Conditions to our or Candid’s obligations to complete the Merger may be waived, in whole or in part, to the extent permitted by law, in certain circumstances unilaterally or by agreement of us and Candid. In the event of a waiver of a condition, our board of directors will evaluate the materiality of any such waiver to determine whether amendment of the related proxy statement/prospectus and re-solicitation of stockholder approval is necessary.

Added

In the event that our board of directors, in its own reasonable discretion, determines any such waiver is not significant enough to require recirculation of the related proxy statement/prospectus and re-solicitation of its stockholders, it will have the discretion to complete the Merger without seeking further stockholder approval, which decision may have a material adverse effect on our stockholders. For example, if we and Candid agree to waive the requirement that the shares of our Common Stock to be issued in the Merger have been approved for listing (subject to official notice of issuance) on Nasdaq as of the closing of the Merger, and their respective boards of directors elect to proceed with the closing of the Merger, Nasdaq may notify the combined company of its determination to delist the combined company’s securities based upon the failure to satisfy the initial inclusion criteria in the Nasdaq application. The combined company may appeal the determination to a hearings panel but such appeal will not stay the suspension and delisting action and Nasdaq may notify the combined company that its common stock will be immediately suspended from trading and delisted.

Added

In addition, in order to meet the initial listing requirements of Nasdaq or as otherwise determined in the discretion of the combined company board pursuant to the terms of the Lock-Up Agreements, our board of directors or combined company board may release stockholders from their Lock-Up Agreements and waive the requirement that such Lock-Up Agreements be in full force and effect immediately following the Effective Time. Such release would increase the number of shares that may be sold in the public market immediately after the Merger and any such sales could cause the combined company’s stock price to decline.

Added

Our winddown of our historical operations, the sale of assets, the suspension of development activities and the proposed Merger, resulting in the conversion of Candid into a public company, will make us subject to the SEC requirements applicable to reporting shell company business combinations. As a result, the combined company will be subject to more stringent reporting requirements, offering limitations and resale restrictions.

Added

According to SEC guidance, the requirements applicable to reporting shell company business combinations apply to any company that sells or otherwise disposes of its historical assets or operations in connection with or as part of a plan to combine with a non-shell private company in order to convert the private company into a public one. As such, our plan to merge with Candid, resulting in the conversion of Candid into a public company, will be subject to the SEC requirements applicable to reporting shell company business combinations, which are as follows:

Added

•the combined company will need to file a Current Report on Form 8-K to report the Form 10 type information (“Super 8-K”) after closing of the Merger reflecting its status as an entity that is not a shell company;

Added

•the combined company will not be eligible to use a Form S-3 until 12 full calendar months after closing of the Merger;

Added

•the combined company will need to wait at least 60 calendar days after the filing of the Super 8-K to file a Form S-8 for any equity plans or awards, such as the 2026 Plan and the 2026 ESPP;

Added

•the combined company will be an “ineligible issuer” for three years following the closing of the Merger, which will prevent the combined company from (i) incorporating by reference in its Form S-1 filings, (ii) using a free writing prospectus or (iii) taking advantage of the well-known seasoned issuer (“WKSI”) status, even if otherwise eligible based on its public float;

Added

•investors who (i) were affiliates of Candid at the time the Merger was submitted for the vote or consent of Candid’s stockholders, (ii) receive securities of the combined company in the Merger and (iii) publicly offer or sell such securities will be deemed to be engaged in a distribution of such securities, and therefore would be underwriters with respect to resales of those securities; and

On March 1, 2026, we entered into the Merger Agreement with Candid, a clinical-stage biotechnology company advancing a leading portfolio of TCE therapeutics for autoimmune diseases, and Merger Sub, a wholly owned subsidiary of Rallybio. Upon the terms and subject to the satisfaction of the conditions described in the Merger Agreement, Merger Sub will be merged with and into Candid, with Candid surviving as a wholly owned subsidiary of Rallybio. The Merger is intended to qualify as a tax-free reorganization for U.S. federal income tax purposes.

Added

Concurrently with the execution and delivery of the Merger Agreement, certain investors entered into subscription agreements with Candid, pursuant to which such investors have agreed to purchase, immediately prior to the Merger, shares of Candid common stock representing an aggregate commitment of approximately $505.5 million in the Concurrent Financing. The shares of Candid common stock that are issued in the Concurrent Financing will be or will have the right to be, respectively, converted into shares of Rallybio Common Stock in the Merger.

Added

Subject to the terms and conditions of the Merger Agreement, at the Effective Time, (a) each then-outstanding share of common stock or preferred stock of Candid (each such share, a “Candid Share”) (excluding any share described in clauses (b) or (c) below and Candid Shares held by stockholders who have exercised and perfected appraisal rights for such shares) will be converted into the right to receive a number of shares of Rallybio Common Stock, calculated in accordance with the Exchange Ratio, (b) each Candid Share issued in the Concurrent Financing will be converted into the right to receive a number of shares of Rallybio Common Stock calculated in accordance with the Merger Agreement, (c) any Candid Shares held as treasury shares or held or owned by Rallybio, Merger Sub or any subsidiary of Rallybio or Candid immediately prior to the Effective Time will be canceled and shall cease to exist, and no consideration shall be delivered in exchange therefor. Each then-outstanding option to purchase Candid Shares will be converted into an option to purchase Rallybio Common Stock, subject to adjustment as set forth in the Merger Agreement.

Added

Under the Exchange Ratio and Concurrent Financing Exchange Ratio formulas in the Merger Agreement, immediately after the Closing, on a pro forma basis and based upon the number of shares of Rallybio Common Stock expected to be issued in connection with the Merger, pre-Merger equityholders of Candid (other than investors in the Concurrent Financing) are expected to own approximately 57.55% of the combined company, pre-Merger equityholders of Rallybio are expected to own approximately 3.65% of the combined company and the Investors in the Concurrent Financing are expected to own approximately 38.80% of the combined company (assuming proceeds from the Concurrent Financing of $505.5 million), in each case, calculated on a fully diluted basis, using the treasury stock method, and subject to certain assumptions, including (i) a valuation for Rallybio of $47.5 million (assuming Rallybio Net Cash of $37.5 million as of the Closing), (ii) a fixed valuation for Candid of $750.0 million, and (iii) the relative capitalization of Rallybio and Candid. The percentage of the combined company that each party’s equity holders will own following the Closing is subject to certain adjustments as described in the Merger Agreement, including the amount of the final Rallybio Net Cash at Closing.

Added

Immediately prior to the Effective Time, Rallybio and a rights agent are expected to enter into a CVR Agreement, pursuant to which holders of record of certain Rallybio securities as of the close of business on the last business day prior to the day on which the Effective Time occurs will receive one CVR for each outstanding share of Rallybio Common Stock, prefunded warrant, Rallybio restricted stock unit or In the Money Parent Option (as defined in the CVR Agreement) held as of such date. Pursuant to the CVR Agreement, each CVR holder will be entitled to receive their pro rata share of (i) all of the net proceeds (including cash the value of stock to the extent listed on a national exchange, at the time of disposition), if any, received by Rallybio as a result of payments made to Rallybio of any upfront, milestone, royalty and other payments received under any disposition agreement related to Rallybio’s Legacy Assets, and (ii) all of the cash proceeds, if any, received from Recursion under the Membership Interest Purchase Agreement, dated July 8, 2025, by and among Recursion, Exscientia Ventures I, Inc., Rallybio Corporation and Rallybio IPB, LLC. For a period of one year after the Closing Date, Rallybio will use commercially reasonable efforts to effect the disposition of the Legacy Assets. Such net proceeds will be subject to certain permitted deductions, including for applicable tax payments, certain expenses incurred or other liabilities borne by Rallybio or its affiliates in respect of the Legacy Assets, and losses incurred by Rallybio or its affiliates due to a third-party proceeding in connection with such disposition.

Added

We completed a confirmatory PK and PD study of RLYB116 in healthy volunteers in 2025 and reported data in the first quarter of 2026.

Added

In July 2025, we entered into a Membership Interest Purchase Agreement (the “ENPP1 Purchase Agreement”) with Recursion Exscientia Ventures I, Inc., an indirect wholly-owned subsidiary of Recursion (“Buyer”) and Rallybio IPB, LLC, a wholly-owned subsidiary of Rallybio Corporation to sell our interest in REV102, an ENPP1 inhibitor in preclinical development for the treatment of patients with HPP, to Buyer (a subsidiary of our joint venture partner Recursion) (the "JV Sale"). In connection with the JV Sale, we received a total of $20.0 million in the third quarter of 2025 including $7.5 million from an upfront payment and $12.5 million from a milestone payment related to the initiation of additional preclinical studies. We are eligible to receive a $5.0 million milestone payment in connection with the initiation of dosing in a Phase 1 clinical study, as defined in the ENPP1 Purchase Agreement and low single-digit royalties on all future net sales by Recursion of products comprising or incorporating certain compounds developed by REV-I. We may also be eligible to receive certain payments in the event of Recursion’s sale of the REV102 program.

Added

In April 2025, we announced the discontinuation of our RLYB212 program for the prevention of FNAIT based on PK data from the Phase 2 clinical trial that demonstrated an inability of the RLYB212 dose regimen to achieve predicted target concentrations, as well as the minimum target concentration required for efficacy.

RLYB212 is a monoclonal anti-HPA-1a antibody for the prevention of FNAIT, a potentially life-threatening rare hematological disease that impacts fetuses and newborns. We are currently conducting a Phase 2 clinical trial of RLYB212 in pregnant women at higher risk for HPA-1a alloimmunization and FNAIT at sites across Europe. The primary objective of this single-arm Phase 2 trial is to assess the PK and safety of RLYB212 with secondary objectives that include assessments of pregnancy and neonatal/infant outcomes, and the occurrence of emergent HPA-1a alloimmunization. Subcutaneous administration of RLYB212 will be initiated by Gestational Week 16 and will continue every four weeks through parturition.

Removed

The Phase 2 trial is designed to enroll participants in three stages: first with a sentinel pregnant woman, an initial Cohort 1 that will include three pregnant women, and a Cohort 2 that will include four pregnant women, for a total target enrollment of eight participants. A data review for participants and infants is planned prior to the initiation of each cohort. Following completion of this Phase 2 dose confirmation trial and consultation with regulatory authorities, we expect to initiate a Phase 3 registrational trial. Both the U.S. FDA and EMA have designated RLYB212 as an orphan drug. Orphan drug designation offers certain incentives including tax credits, marketing exclusivity upon marketing approval, fee waivers, and the ability to interact with both agencies to receive specialized regulatory advice and assistance.

Removed

The Phase 2 trial follows completion of two RLYB212 clinical studies: a Phase 1 first-in-human clinical study and a Phase 1b proof-of-concept clinical study. The Phase 1 first-in-human clinical study was a single-blind, placebo-controlled study that investigated the safety and PK of SC administration of RLYB212 in HPA-1a negative healthy participants. The clinical study included a single dose cohort and a multiple dose cohort. In the multiple dose cohort, subjects received SC RLYB212 or placebo every two weeks for 12 weeks. We reported results from the multi-dose cohort in the fourth quarter of 2023. The data and our clinical pharmacology modeling predictions support a once monthly dosing regimen for the Phase 2 clinical trial.

Removed

In the first quarter of 2023, we announced RLYB212 achieved proof-of-concept in the Phase 1b study. In this study, SC RLYB212 administration produced a dose-dependent, rapid and complete elimination of transfused HPA-1a positive platelets in HPA-1a negative subjects, with both dose groups meeting the pre-specified proof-of-concept criteria of ≥ 90% reduction in mean platelet elimination half-life. Mean platelet elimination half-life was 5.8 hours (0.09mg dose) and 1.5 hours (0.29mg dose) for RLYB212 compared to 71.7 hours for placebo. In both Phase 1 studies, RLYB212 was observed to be generally well-tolerated with no reports of serious or severe adverse events.

We have a prospective, non-interventional, multinational natural history study. This study is designed to screen expectant mothers presenting at gestational week 10 to 14 prenatal visit to determine the frequency of women at higher FNAIT risk among expectant mothers of different racial and ethnic characteristics, as well as the frequency of HPA-1a alloimmunization and pregnancy outcomes among these women. An additional objective of the FNAIT natural history study is to operationalize de novo the laboratory screening test paradigm for FNAIT risk and generate FNAIT laboratory test performance data for future regulatory discussions. We recently transitioned screening activities from the natural history study to the Phase 2 clinical trial where sites will continue to collect natural history data in women who do not receive RLYB212. We expect that natural history data from both the natural history study and the Phase 2 clinical trial will contribute historical control data to support a planned single-arm Phase 3 registrational clinical trial of RLYB212. As of January 31, 2025, more than 14,300 pregnant women had been screened in this study.

Removed

In April 2024, we entered into the J&J Collaboration Agreement, pursuant to which we and J&J will support the development of complementary therapeutic approaches aimed at reducing the risk of FNAIT. Under the J&J Collaboration Agreement, we will share certain aggregated, anonymized data with J&J, collected from the FNAIT natural history study and our RLYB212 Phase 2 clinical trial, where the Phase 2 data will be restricted to certain natural history data in support of the natural history study. We also agreed to disseminate information to our FNAIT study sites related to J&J’s and its affiliates’ research and development of complementary therapeutic approaches aimed at reducing the risk of FNAIT. Pursuant to the agreement, we received an upfront payment of $0.5 million from J&J. In addition, we are eligible for payments upon the achievement of certain enrollment-related events, totaling up to $0.7 million. We are also eligible to receive additional payments upon certain triggers related to the companies' FNAIT studies. In addition, we received an equity investment of $6.6 million from Johnson & Johnson Innovation – JJDC, Inc. ("JJDC"). See "Liquidity and Capital Resources - Sources of Liquidity" below. In connection with the registration requirements and the restrictions on the sale or transfer of the common stock sold, we expect to recognize up to an additional $1.2 million of revenue.

RLYB116 is an innovative, once-weekly, small volume, subcutaneously injected inhibitor of C5 in development for the treatment of patients with complement-related diseases. We have completed two Phase 1 clinical trials in healthy participants that included the study of RLYB116 as both a SAD and a MAD. After the first Phase 1 clinical trial, we completed manufacturing process enhancements that were designed to improve the tolerability of RLYB116. In 2025, we completed the confirmatory Phase 1 clinical trial evaluating the PK/PD properties of RLYB116. The confirmatory trial achieved its two key objectives including: a significant improvement in the tolerability of RLYB116 and demonstration of complete and sustained inhibition of terminal complement. These results support the study of RLYB116 as a potential best-in-class therapeutic for multiple complement mediated diseases.

Removed

We are also developing therapies that address diseases of complement dysregulation, including PNH, APS and gMG. RLYB116 is a novel, potentially long-acting, subcutaneously injected inhibitor of C5 in development for the treatment of patients with complement-related diseases. RLYB114 is a pegylated C5 inhibitor in development for complement-mediated ophthalmic disorders.

Removed

We have completed a Phase 1 clinical study in healthy participants that included the study of RLYB116 as a SAD and a MAD. The SAD portion of the RLYB116 clinical study included five cohorts with a dose ranging from 2mg up to 300mg. Data from the SAD portion of the study showed that all study participants that were administered a single 1 mL SC injection of 100 mg of RLYB116 (n=6) demonstrated a reduction in free C5 greater than 99% within 24 hours of dosing. Subcutaneously administered RLYB116 in the SAD portion of the study was observed to be generally well-tolerated at the 100 mg dose, with mild adverse events and no drug-related serious adverse events reported.

Removed

The MAD portion of the RLYB116 Phase 1 study included an adaptive single-blind design with a 4-week treatment duration to evaluate the safety, tolerability, PK, and PD of RLYB116 with multiple dose SC administration. The MAD portion of the study included four cohorts: Cohort 1 (weekly dosing of 100 mg), Cohort 2 (three doses of 100 mg the first week followed by weekly dosing), Cohort 3 (150 mg weekly dosing reduced to 125 mg weekly dosing) and Cohort 4 (75 mg twice the first week followed by 100 mg twice per week) with post-treatment / study follow-up for 10 weeks. In December 2023, we reported data from the MAD portion of the study that demonstrated a 100 mg low volume (1 mL) once-a-week dose of subcutaneously administered RLYB116 achieved sustained mean reductions in free C5 of greater than 93%, including at Day 29 with measurement prior to the last dose. The reduction from pre-treatment free C5 at 24 hours after the first dose of 100 mg was greater than 99%. RLYB116 administered in the MAD portion of the study as a 100 mg once-a-week dose was also observed to be generally well tolerated.

Removed

Based on the results of the RLYB116 Phase 1 trial, we conducted a series of biomarker characterization analyses. These analyses indicate the RLYB116 assay used to measure free C5 in the Phase 1 trial overestimated the levels of free C5 by approximately ten-fold, indicating that RLYB116 produced greater complement inhibition than initially reported. We now believe that RLYB116 has the potential to be an effective treatment for patients with a variety of complement-mediated diseases, including PNH, gMG and APS. We also completed manufacturing process enhancements with a goal of further improving the tolerability of RLYB116. Based on the results of enhanced analytical techniques, including mass spectrometry, these process enhancements have successfully further purified the RLYB116 drug substance. As a result, we believe that RLYB116 will have a favorable tolerability profile at doses at and above those evaluated in the Phase 1 MAD trial. We plan to initiate a RLYB116 confirmatory clinical PK/PD trial in the second quarter of 2025 to demonstrate improved tolerability as well as complete and sustained complement inhibition. This single-blind MAD trial will evaluate a 4-week treatment duration that will include two cohorts of eight participants each. Our current plan is that Cohort 1 will evaluate weekly dosing of 150 mg and Cohort 2 will evaluate weekly dosing of 225 mg with 10 weeks of follow-up after the conclusion of treatment.

Our collaboration with Exscientia on the discovery of a small molecule targeting an ENPP1 inhibitor for the treatment of HPP has continued after the acquisition of Exscientia by Recursion in 2024. HPP is a rare, genetic disease characterized by mutations in the ALPL gene. The ALPL gene provides instructions for making an enzyme called tissue-nonspecific alkaline phosphatase, which plays an important role in the growth and development of bones and teeth. We believe that a small molecule inhibitor of ENPP1 has the potential to bring meaningful benefit to HPP patients. In 2024, we presented data at the ASBMR from an early lead ENPP1 inhibitor, REV101, in a mouse model of later-onset HPP demonstrating a 30% reduction PPi, a key biomarker that is elevated in HPP and contributes to poor bone mineralization. Together with Recursion, we also advanced REV102, an ENPP1 inhibitor for the treatment of patients HPP to position the molecule for additional preclinical development activities in 2025.

The successful development of any product candidate is highly uncertain. If we are unable to complete the proposed transaction with Candid and continue to progress our product candidates, we will need to raise substantial additional capital in the future to fund the future development of our current programs. We intend to focus our near term research and development efforts on completing the ongoing activities and preparing our programs for a potential transaction or sale.

The successful development of our product candidates is highly uncertain. We plan to continue investing in our research and development activities for the foreseeable future as we continue the development of our product candidates and the related manufacturing processes and conduct discovery and research activities for our clinical programs. We cannot determine with certainty the timing of initiation, the duration or the completion costs of current or future clinical trials of our product candidates due to the inherently unpredictable nature of preclinical and clinical development. Clinical development timelines, the probability of success and development costs can differ materially from expectations. We anticipate that we will make determinations as to which product candidates to pursue and how much funding to direct to each product candidate on an ongoing basis in response to the results of ongoing and future clinical trials, regulatory developments, our ongoing assessments as to each product candidate’s commercial potential and the availability of capital. We will need to raise substantial additional capital in the future. Our clinical development costs are expected to increase significantly as our programs advance to later stages of development.

Risks Related to the Merger

Added

Failure to complete, or delays in completing, the proposed Merger with Avenzo could materially and adversely affect our results of operations, business, financial results and/or stock price.

Added

Any failure to satisfy a required condition to closing may prevent, delay or otherwise materially and adversely affect the completion of the Merger, which could materially and adversely affect our results of operations, business, financial results and/or stock price. We cannot predict with certainty whether or when any of the required closing conditions will be satisfied or if another uncertainty may arise and cannot assure you that the proposed Merger will be successfully consummated or that we will be able to successfully consummate the proposed Merger as currently contemplated under the Merger Agreement or at all.

Added

Even if certain of the proposals in the Merger Agreement are approved by our stockholders, specified conditions must be satisfied or, to the extent permitted by applicable law, waived to complete the Merger. We cannot assure you that all of the conditions will be satisfied or waived.

Added

Risks related to the failure to consummate, or delay in consummating, the proposed Merger with Avenzo include, but are not limited to, the following:

Added

▪we would not realize any or all of the potential benefits of the Merger, which could have a negative effect on our results of operations, business or stock price;

Added

▪under some circumstances, we may be required to pay a termination fee to Avenzo, with expense reimbursement credited against the payment of any such termination fee;

Added

▪we would remain liable for significant transaction costs, including legal, accounting, financial advisory and other costs relating to the Merger regardless of whether the Merger is consummated;

Added

▪the trading price of our common stock may decline to the extent that the current market price for our common stock reflects a market assumption that the Merger will be completed;

Added

▪the attention of our management and employees may have been diverted to the Merger rather than to our historical operations and the pursuit of other opportunities that could have been beneficial to us;

Added

▪we could be subject to litigation related to any failure to complete the Merger;

Added

▪we could potentially lose key personnel during the pendency of the Merger; and

Added

▪under the Merger Agreement, we are subject to certain customary restrictions on the conduct of our business prior to completing the Merger, which restrictions could adversely affect our ability to conduct our business as we otherwise would have done if we were not subject to these restrictions.

Added

The occurrence of any of these events individually or in combination could materially and adversely affect our results of operations, business, and our common stock price, and we may lose some or all the intended benefits of the Merger.

Added

We are substantially dependent on our remaining employees to facilitate the consummation of the Merger.

Added

Our ability to consummate a strategic transaction depends upon our ability to retain our remaining employees required to consummate such a transaction, the loss of whose services may adversely impact the ability to consummate such transaction. As of June 30, 2026, we had only 7 full-time employees. Our ability to successfully complete the Merger depends in large part on our ability to retain key personnel that are necessary to maintain our operations between now and the Effective Time. Despite our efforts to retain these employees, one or more may terminate their employment with us on short notice. Our cash conservation activities may yield other unintended consequences, such as reduced employee morale, which may cause remaining employees to seek alternative employment. The loss of the services of certain employees could potentially harm our ability to consummate the Merger, to run our day-to-day business operations, as well as to fulfill our reporting obligations as a public company.

Added

The Exchange Ratio will not be adjusted based on the market price of our common stock, so the consideration at the closing of the Merger may have a greater or lesser value than at the time the Merger Agreement was signed.

Added

The Exchange Ratio will not change based on changes in the trading price of our common stock. Therefore, if before the completion of the Merger, the market price of our common stock increases from the market price on the date of the Merger Agreement, Avenzo stockholders could then receive merger consideration with substantially higher value for their shares of Avenzo common stock than the parties had negotiated when they established the Exchange Ratio. The Merger Agreement does not include a price-based termination right. Immediately after the Merger, our securityholders as of immediately prior to the Merger are expected to own approximately 2.8% of the outstanding shares of the combined company and former Avenzo securityholders, including purchasers in the Concurrent Financing, are expected to own approximately 97.2% of the outstanding shares of the combined company, subject to certain assumptions, including, but not limited to, in each case, calculated on a fully diluted basis, using the treasury stock method, and subject to certain assumptions, including (i) a valuation for Rallybio of $15.0 million (calculated after giving effect to the expected payment of the distribution of Rallybio's pre Closing cash), (ii) a valuation for Avenzo of $300.0 million, and (iii) the relative capitalization of Rallybio and Avenzo.

Added

The Merger may be completed even though a material adverse effect may result from the announcement of the Merger, industry-wide changes and/or other causes.

Added

In general, either we or Avenzo can refuse to complete the Merger if there is a Rallybio Material Adverse Effect (as defined in the Merger Agreement) or a Company Material Adverse Effect (as defined in the Merger Agreement), as applicable, prior to the Closing. However, certain types of changes do not permit either party to refuse to complete the Merger, even if such change could be said to have a material adverse effect on us or Avenzo, including:

Added

▪general business, political or economic conditions generally affecting the industry in which Rallybio or Avenzo operate, including with respect to the imposition of, or adjustments to, tariffs or other trade restrictions;

Added

▪acts of war, the outbreak or escalation of armed hostilities, acts of terrorism, earthquakes, wildfires, hurricanes or other natural disasters, health emergencies, including pandemics and related or associated epidemics, disease outbreaks or quarantine restrictions;

Added

▪changes in financial, banking or securities markets;

Added

▪any change in the stock price or trading volume of Rallybio Common Stock (it being understood, however, that any effect causing or contributing to any change in stock price or trading volume of Rallybio Common Stock may be taken into account in determining whether a material adverse effect with respect to Rallybio has occurred, unless such effects are otherwise excepted from the definition of Rallybio Material Adverse Effect);

Added

▪any failure by Rallybio to meet internal or analysts’ expectations or projections or the results of operations of Rallybio (it being understood, however, that any effect causing or contributing to the failure of Rallybio to meet internal or analysts’ expectations or projections or the results of operations of Rallybio may be taken into account in determining whether a material adverse effect with respect to Rallybio has occurred, unless such effects are otherwise excepted from the definition of Rallybio Material Adverse Effect);

Added

▪any change in, or any compliance with or action taken for the purpose of complying with, any applicable law or GAAP (or interpretations of any applicable law or GAAP);

Added

▪the announcement of the Merger Agreement or the pendency of the Contemplated Transactions; or

Added

▪the taking of any action required to be taken by the Merger Agreement.

Added

If a material adverse change occurs with respect to either party or both parties and we and Avenzo still complete the Merger, the stock price of the combined company following the Closing may suffer and may reduce the value of the Merger to the stockholders of Rallybio, Avenzo or both.

Added

Some of our executive officers and directors have interests in the Merger that are different from our stockholders and that may influence them to support or approve the Merger without regard to the interests of our stockholders.

Added

Certain of our executive officers and directors of Rallybio are parties to arrangements that provide them with interests in the Merger that are different from our stockholders, including severance benefits, the acceleration of equity award vesting and continued indemnification. The Board was aware of and considered these interests, among other matters, in reaching its determination (i) that the terms of the Merger Agreement and the Merger and the other Contemplated Transactions are fair to, advisable and in the best interest of Rallybio and its stockholders; and (ii) to approve and declare advisable the Merger Agreement and the Contemplated Transactions, including the Merger and the issuance of shares of Rallybio common stock to the stockholders of Avenzo pursuant to the Merger Agreement.

Added

Our stockholders may not realize a benefit from the Merger commensurate with the ownership dilution they will experience in connection with the Merger.

Added

If the combined company is unable to realize the full strategic and financial benefits currently anticipated from the Merger, our stockholders will have experienced substantial dilution of their ownership interests without receiving any commensurate benefit, or only receiving part of the commensurate benefit to the extent the combined company is able to realize only part of the strategic and financial benefits currently anticipated from the Merger.

Added

Our equityholders will have a reduced ownership and voting interest in, and will exercise less influence over the management of, the combined company following the completion of the Merger as compared to their current ownership and voting interests in the respective companies.

Added

After the completion of the Merger, our current stockholders will own a smaller percentage of the combined company than their ownership of Rallybio prior to the Merger. Immediately after the Closing, on a pro forma basis and based upon the number of shares of Rallybio Common Stock expected to be issued in connection with the Merger, pre-Merger equityholders of Avenzo (other than investors in the Concurrent Financing) are expected to own approximately 56.6% of the combined company, pre-Merger equityholders of Rallybio are expected to own approximately 2.8% of the combined company and the investors in the Concurrent Financing are expected to own approximately 40.6% (assuming proceeds from the Concurrent Financing of $215.0 million), in each case, calculated on a fully diluted basis, using the treasury stock method, and subject to certain assumptions, including (i) a valuation for Rallybio of $15.0 million (calculated after giving effect to expected payment of Parent Distributions), (ii) a fixed valuation for Avenzo of $300.0 million, and (iii) the relative capitalization of Rallybio and Avenzo.

Added

The amount of the Rallybio Distributions is uncertain and may be less than currently anticipated, or the Rallybio Distributions may not be made at all.

Added

In connection with the Merger, the Board will declare one or more Rallybio Distributions payable to holders of Rallybio common stock and, if applicable, securities convertible into or exchangeable or exercisable for shares of Rallybio common stock, in an aggregate amount not to exceed the amount by which Rallybio Net Cash equals or exceeds $0. The amount of Rallybio Net Cash available for the Rallybio Distributions is subject to numerous factors, many of which are outside of our control, including the amount of our transaction expenses, the costs of any tail policy associated with our directors’ and officers’ insurance, lease termination costs, payments required to terminate existing agreements, expenses associated with the wind-down of our prior research and development activities, payroll taxes associated with the Rallybio Distributions, severance or change-in-control payments, and other accrued or contingent liabilities. We expect to continue to incur losses in future periods primarily related to the proposed Merger and, as a result, available cash and cash equivalents will continue to decrease prior to the Closing. If these expenses and liabilities are greater than currently estimated, or if unforeseen liabilities arise, the amount available for the Rallybio Distributions will be reduced accordingly. There can be no assurance that the aggregate amount of the Rallybio Distributions will equal the amount that our stockholders currently expect to receive, or that any Rallybio Distribution will be made at all.

Added

Lawsuits may be filed against us and the members of our Board arising out of the proposed Merger, which may delay or prevent the proposed Merger.

Added

Putative stockholder complaints, including stockholder class action complaints, and other complaints may be filed against us, our Board and others in connection with the transactions contemplated by the Merger Agreement. The outcome of litigation is uncertain, and we may not be successful in defending against any such future claims. Lawsuits that may be filed against us, our board, Avenzo, or the Avenzo board could delay or prevent the Merger, divert the attention of our management and employees from our day-to-day business and otherwise adversely affect our financial condition.

Added

During the pendency of the Merger Agreement, we may not be able to enter into a business combination with another party at a favorable price because of restrictions in the Merger Agreement, which could adversely affect our business.

Added

Covenants in the Merger Agreement impede our ability to make acquisitions, subject to specified exceptions relating to fiduciary duties, or complete other mergers, sales of assets or other business combinations pending completion of the Merger. As a result, if the Merger is not completed, we may be at a disadvantage to our competitors during that period. In addition, while the Merger Agreement is in effect, we are generally prohibited from soliciting, initiating, knowingly encouraging or entering into specified extraordinary transactions, such as a merger, sale of assets or other business combination, with any third party, subject to specified exceptions, even if any such transaction could be favorable to our stockholders.

Added

Certain provisions of the Merger Agreement may discourage third parties from submitting competing proposals, including proposals that may be superior to the arrangements contemplated by the Merger Agreement.

Added

The terms of the Merger Agreement prohibit us from soliciting competing proposals or cooperating with persons making unsolicited takeover proposals, except in certain limited circumstances. Our Board may respond to an unsolicited competing proposal if it determines in good faith, after consultation with its outside financial advisor and outside legal counsel, that the unsolicited competing proposal constitutes, or is reasonably likely to result in, a superior competing proposal and, after consultation with its outside legal counsel, that failure to take such action would be inconsistent with the fiduciary duties of the Board. In certain circumstances, and subject to compliance with the Merger Agreement, our Board may change its recommendation to our stockholders if it determines such recommendation change is required to avoid a breach of its fiduciary duties.

Added

Upon termination of the Merger Agreement in certain circumstances, a termination fee of $600,000 may be payable by us to Avenzo if (i)(a) the Merger Agreement is terminated because the Merger has not been consummated by the End Date (as defined in the Merger Agreement) or we (1) fail to obtain the requisite stockholder approval or (2) breach the Merger Agreement, (b) an alternative acquisition proposal was announced or disclosed prior to such termination, and (c) within 12 months of the termination of the Merger Agreement, we enter into a definitive agreement with respect to an alternative transaction or (ii) the Board of changes or withdraws its recommendation in favor of the Merger or approves an alternative transaction, or willfully and intentionally breaches its non-solicitation or certain other obligations under the Merger Agreement.

Added

We have also agreed to reimburse Avenzo for up to $750,000 for third-party expenses, as applicable, if the Merger Agreement is terminated in certain circumstances.

Added

These termination fees and expense reimbursement provisions may discourage third parties from submitting competing proposals to us or our stockholders and may cause our Board to be less inclined to recommend a competing proposal.

Added

We or Avenzo may waive one or more of the conditions to the Merger without recirculation of the related proxy statement/prospectus or resoliciting stockholder approval.

Added

Conditions to our or Avenzo’s obligations to complete the Merger may be waived, in whole or in part, to the extent permitted by law, in certain circumstances unilaterally or by agreement of us and Avenzo. In the event of a waiver of a condition, our Board will evaluate the materiality of any such waiver to determine whether amendment of the related proxy statement/prospectus and re-solicitation of stockholder approval is necessary.

Added

In the event that our Board, in its own reasonable discretion, determines any such waiver is not significant enough to require recirculation of the related proxy statement/prospectus and re-solicitation of our stockholders, it will have the discretion to complete the Merger without seeking further stockholder approval, which decision may have a material adverse effect on our stockholders. For example, if we and Avenzo agree to waive the requirement that the shares of Rallybio common stock to be issued in the Merger have been approved for listing (subject to official notice of issuance) on Nasdaq as of the Closing, and our respective boards of directors elect to proceed with the Closing, Nasdaq may notify the combined company of its determination to delist the combined company’s securities based upon the failure to satisfy the initial inclusion criteria in the Nasdaq application. The combined company may appeal the determination to a hearings panel but such appeal will not stay the suspension and delisting action and Nasdaq may notify the combined company that its common stock will be immediately suspended from trading and delisted.

Added

Our winddown of our historical operations, the sale of assets, the suspension of development activities and the proposed Merger, resulting in the conversion of Avenzo into a public company, will make us subject to the SEC requirements applicable to reporting shell company business combinations. As a result, the combined company will be subject to more stringent reporting requirements, offering limitations and resale restrictions.

Added

According to SEC guidance, the requirements applicable to reporting shell company business combinations apply to any company that sells or otherwise disposes of its historical assets or operations in connection with or as part of a plan to combine with a non-shell private company in order to convert the private company into a public one. We have taken steps to winddown our general and administrative operations that will not be needed after Closing and expect to issue the CVRs in connection with the Closing and, as such, our plan to merge with Avenzo, resulting in the conversion of Avenzo into a public company, will be subject to the SEC requirements applicable to reporting shell company business combinations, which are as follows:

Added

•the combined company will need to file a Current Report on Form 8-K to report the Form 10 type information (“Super 8-K”) after the Closing reflecting its status as an entity that is not a shell company;

Added

•the combined company will not be eligible to use a Form S-3 until 12 full calendar months after the Closing;

Added

•the combined company will need to wait at least 60 calendar days after the filing of the Super 8-K to file a Form S-8 for any equity plans or awards, such as the 2026 Plan and the 2026 ESPP;

Added

•the combined company will be an “ineligible issuer” for three years following the Closing, which will prevent the combined company from (i) incorporating by reference in its Form S-1 filings, (ii) using a free writing prospectus or (iii) taking advantage of the well-known seasoned issuer (“WKSI”) status, even if otherwise eligible based on its public float;

Added

•investors who (i) were affiliates of Avenzo at the time the Merger was submitted for the vote or consent of Avenzo’s stockholders, (ii) receive securities of the combined company in the Merger and (iii) publicly offer or sell such securities will be deemed to be engaged in a distribution of such securities, and therefore would be underwriters with respect to resales of those securities; and

Added

•Rule 144(i)(2) will limit the ability of holders of restricted securities, and any affiliates of the public company to publicly resell Rule 145(c) securities per Rule 145(d), as well as any other “restricted” or “control” securities of the combined company per Rule 144, until one year after the Form 10 information is filed with the SEC. Non-affiliate Rallybio stockholders prior to the Merger will not be subject to such restrictions on public resales of their shares.

Added

The foregoing SEC requirements will increase the combined company’s time and cost of raising capital, offering stock under equity plans, and complying with securities laws. Furthermore, such requirements will add burdensome restrictions on the resale of the combined company common stock by affiliates of Avenzo and any holders of “restricted” or “control” securities of the combined company.

Added

Our equityholders may not receive any payment on the CVRs and the CVRs may otherwise expire valueless.

Added

The right of our equityholders to receive any future payment for or derive any value from the CVRs will be contingent solely upon (i) our and Avenzo’s (or the combined company’s) ability to monetize all or any part of the Legacy Assets pursuant to one or more disposition agreements entered into within the time period specified in the CVR Agreement, and the timing and amount of the consideration received thereunder and (ii) the receipt of cash proceeds from Recursion under the ENPP1 Purchase Agreement. If we and/or Avenzo or the combined company (x) are not successful in entering into disposition agreements related to the Legacy Assets or receiving payments thereunder, or if such payments are not sufficient to result in the payment of any CVR Payments as a result of permitted deductions thereto and (y) do not receive cash proceeds from Recursion pursuant to the ENPP1 Purchase Agreement, in each case within the time period specified in the CVR Agreement, no payments will be made in respect of the CVRs, and the CVRs will expire valueless.

Reworded

On March 1, 2026, Rallybio Corporation and subsidiaries ("Rallybio", the "Company", "we", "our", or "us") entered into an Agreement and Plan of Merger and Reorganization with Candid Therapeutics, Inc ("Candid") (the "Candid Merger Agreement") pursuant to which the parties intended to undertake a business combination (the "Candid Merger").

Reworded

On May 3, 2026, Candid terminated the Candid Merger Agreement concurrently with entering into a Permitted Alternative Agreement (as defined in the Candid Merger Agreement) with UCB S.A. (“UCB”). As a result of the termination of the Candid Merger Agreement, we were paid on May 4, 2026 a $50.0 million Parent Termination Fee (as defined in the Candid Merger Agreement) and were reimbursed $0.4 million for certain expenses.

Added

Following termination of the Candid Merger Agreement, Rallybio restarted the evaluation of strategic alternatives. On May 31, 2026, Rallybio entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) with Avenzo Therapeutics, Inc.(“Avenzo”), a clinical-stage biotechnology company developing next-generation oncology therapies, pursuant to which, among other matters, Farmington Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Rallybio (“Merger Sub”), will merge with and into Avenzo with Avenzo surviving as a wholly owned subsidiary of Rallybio (such transaction, the “Merger”). In connection with the Merger, Rallybio will change its name to Avenzo Therapeutics, Inc. (together with its subsidiaries following the Merger, the “combined company”). The Merger is intended to qualify as a tax-free reorganization for U.S. federal income tax purposes. The Merger will become effective at the time the Certificate of Merger has been duly filed with the Secretary of State of the State of Delaware or such other date and time as is agreed upon by Rallybio and Avenzo and specified in the Certificate of Merger in accordance with the General Corporation Law of the State of Delaware (“DGCL”) (such date, the “Closing Date,” and such time, the “Effective Time”).

Added

In connection with the Merger, Avenzo entered into a subscription agreement (the “Subscription Agreement”) with certain investors, pursuant to which Avenzo has agreed to sell, and such investors have agreed to purchase, shares of Avenzo Common Stock for an aggregate purchase price of $215.0 million, immediately prior to the Effective Time (such transaction, the “Concurrent Financing”). The closing of the Concurrent Financing is conditioned upon the satisfaction or waiver of each of the conditions to the closing of the Merger (the “Closing”) as well as certain other conditions.

Added

Subject to the terms and conditions of the Merger Agreement, at the Effective Time, (a) each then-outstanding share of common stock or preferred stock of Avenzo (each such share, an “Avenzo Share”) (excluding any share described in clauses (b) or (c) below and Avenzo Shares held by stockholders who have exercised and perfected appraisal rights for such shares) will be converted into the right to receive a number of shares of Rallybio common stock, calculated in accordance with the Exchange Ratio as set forth in the Merger Agreement, (b) each Avenzo Share issued in the Concurrent Financing will be converted into the right to receive a number of shares of Rallybio common stock calculated in accordance with the Merger Agreement, (c) any Avenzo Shares held as treasury shares or held or owned by Rallybio, Merger Sub or any subsidiary of Rallybio or Avenzo immediately prior to the Effective Time will be canceled and shall cease to exist, and no consideration shall be delivered in exchange therefor. Each then-outstanding option to purchase Avenzo Shares will be converted into an option to purchase Rallybio common stock, subject to adjustment as set forth in the Merger Agreement.

Added

Under the Exchange Ratio formula in the Merger Agreement, upon the Closing, on a pro forma basis and based upon the number of shares of Rallybio common stock expected to be issued in connection with the Merger and the Concurrent Financing, pre-Merger equityholders of Avenzo (other than investors in the Concurrent Financing) are expected to own approximately 56.6% of the combined company, pre-Merger equityholders of Rallybio will own approximately 2.8% of the combined company and the investors in the Concurrent Financing are expected to own approximately 40.6% (assuming gross proceeds from the Concurrent Financing of $215.0 million), in each case, calculated on a fully diluted basis, using the treasury stock method, and subject to certain assumptions, including (i) a valuation for Rallybio of $15.0 million (calculated after giving effect to the expected payment of the distribution of Rallybio's pre Closing cash), (ii) a valuation for Avenzo of $300.0 million, and (iii) the relative capitalization of Rallybio and Avenzo. The percentage of the combined company that each party’s equityholders will own following the Closing is subject to certain adjustments as described in the Merger Agreement, including the amount of the final Rallybio Net Cash (as defined in the Merger Agreement) at Closing. At any time prior to the Closing, Rallybio will declare distributions (each a “Rallybio Distribution”) of Rallybio Net Cash to holders of Rallybio common stock and, if applicable, securities convertible into or exchangeable or exercisable for shares of Rallybio common stock outstanding as of the applicable record date, subject to the terms of the Merger Agreement.

Added

Immediately prior to the Effective Time, Rallybio and a rights agent (the “Rights Agent”) are expected to enter into a Contingent Value Rights Agreement (the “CVR Agreement”), pursuant to which holders of record of certain Rallybio securities as of the close of business on the last business day prior to the Closing Date will receive one contingent value right (each, a “CVR”) for each outstanding share of Rallybio common stock, pre-funded warrant, Rallybio restricted stock unit or In the Money Parent Option (as defined in the Merger Agreement) held as of such date. Pursuant to the CVR Agreement, each CVR holder will be entitled to receive their pro rata share of all of the net proceeds (including cash or the value of stock to the extent listed on a national exchange, at the time of disposition), if any, received by Rallybio as a result of payments (“CVR Payments”) made to Rallybio of (i) any upfront, milestone, royalty and other payments received under any disposition agreement related to Rallybio’s pre-Merger assets (the “Legacy Assets”), and (ii) all of the cash proceeds, if any, received from Recursion Pharmaceuticals, Inc. ("Recursion") under the Membership Interest Purchase Agreement, dated July 8, 2025, by and among Recursion, Exscientia Ventures I, Inc., Rallybio and Rallybio IPB, LLC (the “ENPP1 Purchase Agreement”). For a period of four months after the Closing Date, Rallybio will use commercially reasonable efforts to effect the disposition of the Legacy Assets with respect to a third party that Rallybio had been in discussions with regarding a disposition prior to the Closing Date, subject to certain limitations. Such net proceeds will be subject to certain permitted deductions, including for applicable tax payments, certain expenses incurred or other liabilities borne by Rallybio or its affiliates in respect of the Legacy Assets, and losses incurred by Rallybio or its affiliates due to a third-party proceeding in connection with such disposition.

Reworded

In July 2025, we entered into a Membership Interest Purchase Agreement (the “ENPP1 Purchase Agreement”) with Recursion Exscientia Ventures I, Inc., an indirect wholly-owned subsidiary of Recursion (“Buyer”) and Rallybio IPB, LLC, a wholly-owned subsidiary of Rallybio Corporation to sell our interest in REV102, an Ectonucleotide Pyrophosphatase/Phosphodiesterase 1 ("ENPP1") inhibitor in preclinical development for the treatment of patients with hypophosphatasia ("HPP"), to Buyer (a subsidiary of our joint venture partner Recursion) (the "JV Sale"). In connection with the JV Sale, we received a total of $20.0 million in the third quarter of 2025 including $7.5 million from an upfront payment and $12.5 million from a milestone payment related to the initiation of additional preclinical studies. We are eligible to receive a $5.0 million milestone payment in connection with the initiation of dosing in a Phase 1 clinical study, as defined in the ENPP1 Purchase Agreement and low single-digit royalties on all future net sales by Recursion of products comprising or incorporating certain compounds developed by RE Ventures I, LLC, a limited liability company (“REV-I”). We may also be eligible to receive certain payments in the event of Recursion’s sale of the REV102 program.

As of MarchJune 31,30, 2026, we had cash,cash and cash equivalents and marketable securities of $46.8$92.8 million. We believe that our existing cash,cash and cash equivalents and marketable securities will be sufficient to fund our operating expenses and capital expenditure requirements for at least 12 months beyond the filing of this Quarterly Report on Form 10-Q.10-Q, although we anticipate that the Merger will close prior to the end of 2026. See “—Liquidity and Capital Resources.”

We have incurred significant operating losses since inception, including netoperating losses of $8.3$5.7 million and $9.4$10.1 million for the three months ended MarchJune 31,30, 2026 and 2025, respectively and $14.4 million and $19.7 million for the six months ended June 30, 2026 and 2025, respectively. The increase in total other income of $50.0 million was a result of the termination of the Candid Merger Agreement on May 4, 2026 and payment of the related termination fee. As of MarchJune 31,30, 2026, we had an accumulated deficit of $310.3$266.6 million. These losses have resulted primarily from costs incurred in connection with research and development activities and general and administrative costs associated with our operations. We have not commercialized any products and have never generated revenue from the commercialization of any product. There can be no assurances, however, that additional funding will be available on terms acceptable to us, or at all.

In April 2024, we also entered into the JJDC Securities Purchase Agreement. Under the terms of the JJDC Securities Purchase Agreement, JJDC made an equity investment purchasing 454,545 shares of common stock with a par value of $0.0001 per share for a share purchase price of $14.56 per share which includes a 10% premium for an aggregate purchase price of $6.6 million. The JJDC Securities Purchase Agreement contains provisions related to the registration of the shares and the restriction on the sale or transfer of the shares for a period of time. We determined the J&J Collaboration Agreement and JJDC Securities Purchase Agreement represented combined agreements. In accordance with Accounting Standards Codification 606, Revenue Recognition and Accounting Standards Codification Topic 820, Fair Value Measurement, total consideration of $1.2 million for the shares of common stock from the JJDC Securities Purchase Agreement, which represents the premium of $0.7 million and discount for lack of marketability of $0.5 million, has been allocated to revenue and will bewas recognized over the two-year expected performance period. As of MarchJune 31,30, 2026, all revenue was recognized due to the performance obligations being satisfied. On April 9, 2026, the J&J Collaboration Agreement terminated upon completion of the initial term of the agreement.
