Rallybio Corporation (RLYB) approved a one-for-two reverse stock split, expected to take effect at 12:01 a.m. Eastern Time on November 20, 2026.
Before the merger, issued and outstanding common shares are expected to decrease from approximately 5.6 million to approximately 2.8 million. The split will not change the authorized share count or the $0.0001 par value per share; shares underlying pre-funded warrants and equity awards, and equity plan reserves, will be adjusted proportionately under their applicable terms. Holders otherwise entitled to fractional shares will receive cash based on the fair market value of the fraction, using the closing price on the effective date. After applicable Nasdaq approvals and merger closing, Rallybio plans to change its name to Avenzo Therapeutics, Inc. and trade under the symbol AVZO.
Rallybio Corp (RLYB) and Avenzo Therapeutics, Inc. postponed the closing of their merger, which Rallybio had anticipated for November 6, 2026, subject to outstanding closing conditions. The parties said certain conditions related to listing Rallybio shares following the closing were not satisfied and that they would continue seeking the applicable listing approvals. Farmington Merger Sub, Inc. is also a party to the merger agreement.
Because the closing was postponed, Rallybio did not deposit funds for the previously announced cash distribution with Computershare on November 5, 2026. The distribution’s previously announced payment date and ex-dividend date may be delayed. Rallybio said it would provide further updates as it deems appropriate or necessary under applicable law and regulations.
Rallybio Corp. stockholders approved the merger-related issuance of common stock to Avenzo securityholders, which will represent more than 20% of shares outstanding immediately before the merger and result in a change of control. The merger is expected to close November 6, 2026, subject to satisfaction or waiver of outstanding closing conditions.
Stockholders also approved a reverse split ranging from 1-for-2 to 1-for-9, with the final ratio to be mutually determined by Rallybio and Avenzo; neither intends to effect it before merger closing. They approved changing the company name to Avenzo Therapeutics, Inc. and increasing authorized common stock from 200,000,000 to 500,000,000 shares. The 2026 equity plan’s initial reserve is 18% of post-merger common stock issued and outstanding; the employee stock purchase plan’s initial limit is 1% of shares issued and expected to be outstanding immediately after the merger. Both plans are contingent on closing.
Rallybio set an aggregate $83.6 million cash distribution, or $13.90 per share, for stockholders and pre-funded warrant holders of record November 5, 2026, subject to due-bill procedures. The due-bill period runs through the close of trading November 6, and the transfer agent is expected to begin payments November 13.
Rallybio Corp. (RLYB) declared a special cash distribution estimated at $82.7 million, or $13.56 per share, for stockholders and pre-funded warrant holders. The estimate is based on the company’s good-faith calculation of net cash above $0 under the merger agreement; the actual distribution may be higher or lower. Payment is conditioned on receipt of the Required Company Stockholder Vote at the annual meeting scheduled for November 4, 2026.
The record date is November 5, 2026, subject to change based on the stockholder meeting date. The company plans to deposit the actual distribution with its transfer agent that day, with payment scheduled for November 13, 2026. The merger with Avenzo Therapeutics, Inc. is expected to close on or about November 6, subject to stockholder approval and satisfaction or waiver of the merger agreement’s conditions. The expected November 4–6 due-bill period means sellers deliver the distribution to buyers of shares traded during that period.
Rallybio Corp (RLYB) reported a change in the work arrangement of its Chief Financial Officer, Jonathan LieberSeptember 15, 2026base salary of $420,000Avenzo Therapeutics, Inc.May 31, 2026
Rallybio Corporation announced a definitive agreement to acquire Avenzo Therapeutics in an all‑stock reverse‑triangular merger combined with a $215.0 million concurrent private financing. Avenzo will become a wholly owned Rallybio subsidiary, and the combined company is expected to be renamed Avenzo Therapeutics and trade on Nasdaq as “AVZO.”
Based on an implied valuation of $15.0 million for Rallybio and $300.0 million for Avenzo and assuming Rallybio distributes substantially all pre‑closing net cash, pre‑transaction Rallybio equityholders are expected to own about 2.8% of the combined company and pre‑transaction Avenzo equityholders, including financing investors, about 97.2%, on a fully diluted treasury‑stock basis.
Rallybio stockholders will also receive contingent value rights tied to potential future proceeds from legacy asset dispositions. The combined company expects its cash at closing, including the $215.0 million financing, to fund operations into late 2028 and advance four clinical‑stage oncology programs through multiple Phase 1 updates and the start of several Phase 2 studies.
Rallybio Corporation’s planned merger with Candid Therapeutics will not proceed after Candid ended their agreement and signed a Permitted Alternative Agreement with UCB S.A. Instead of completing the transaction, Rallybio is entitled to receive a $50,000,000 Parent Termination Fee from Candid under the merger terms.
Rallybio, Candid and UCB also signed a waiver on May 1, 2026 that adjusts certain notice rights, allows payment of the termination fee and expense reimbursements on the first business day after termination, and includes broad mutual releases of claims related to the merger agreements and contemplated transactions. Rallybio plans to withdraw its previously filed Form S-4 registration statement.
Rallybio Corporation reported that Chief Medical Officer Steven Ryder, M.D., who has served in that role since January 2019, has left the company effective immediately. His departure occurs as Rallybio pursues a pending business combination with Candid Therapeutics, Inc. under a previously announced merger agreement.
Under a new separation agreement, Dr. Ryder will receive severance payments and benefits consistent with a termination by Rallybio without cause, as outlined in his existing employment agreement. After the closing of the Candid merger and related change of control, he is entitled to additional severance owed for a without-cause termination following a change of control, reduced by the initial severance amounts already paid.
Rallybio states that Dr. Ryder’s restricted stock, stock options and other equity awards will remain outstanding and may continue to vest according to the merger agreement. These awards will remain exercisable until 90 days following the closing of the merger, providing a limited post-closing window for exercise.
Rallybio Corporation agreed to merge with clinical-stage biotech Candid Therapeutics in a stock deal that will leave Candid’s investors owning the vast majority of the combined company. A concurrent private financing will provide $505.5 million of new capital to support Candid’s T‑cell engager pipeline for autoimmune diseases.
Based on agreed valuations and assuming Rallybio net cash of $37.5 million, pre‑transaction Rallybio holders are expected to own about 3.65% of the combined company, while Candid holders (including new investors) will own about 96.35%. The new entity will be renamed Candid Therapeutics, Inc. and is expected to trade on Nasdaq under ticker “CDRX”.
Rallybio stockholders will receive contingent value rights tied to cash proceeds from dispositions of Rallybio’s legacy assets. Closing requires shareholder approvals, an effective Form S‑4, completion of at least $200 million of the financing, Nasdaq listing approvals and antitrust clearance, among other customary conditions. Rallybio also reports it has regained compliance with Nasdaq’s minimum bid price rule following a 1‑for‑8 reverse stock split.
Rallybio Corporation approved and scheduled a 1-for-8 reverse stock split of its common stock. The split will become effective at 12:01 a.m. Eastern Time on February 6, 2026, after which the stock will trade on a post-split basis under a new CUSIP.
Stockholders approved the amendment at a special meeting, with 34,507,021 votes in favor, 464,514 against, and 11,939 abstentions. As of the December 30, 2025 record date, 42,243,774 shares were outstanding and entitled to vote, and 34,983,474 shares were represented, constituting a quorum.
Rallybio Corporation (RLYB) furnished an 8-K stating it issued a press release announcing financial results for the quarter ended September 30, 2025. The press release is included as Exhibit 99.1.
The company noted that the information in Item 2.02, including Exhibit 99.1, is furnished and not deemed “filed” under the Exchange Act, which limits potential liability and incorporation by reference unless specifically stated.
Rallybio Corporation received an additional grace period from Nasdaq to fix a share price problem that threatens its stock market listing. After its common stock traded below the required $1.00 minimum closing bid price for 30 straight business days and failed to recover by the initial August 25, 2025 deadline, Nasdaq approved the company’s transfer from the Nasdaq Global Select Market to the Nasdaq Capital Market.
The transfer took effect at the opening of business on August 29, 2025, and the stock continues to trade under the symbol “RLYB”. Rallybio now has until February 23, 2026 to regain compliance with Nasdaq’s bid price rule. The company plans to monitor its share price and is considering options to restore compliance, including a potential reverse stock split if needed.
If Rallybio does not meet the minimum bid price requirement by the new deadline, Nasdaq may move to delist the stock, although the company would have the right to appeal that decision to a Nasdaq Hearings Panel.
Rallybio Corporation (NASDAQ: RLYB) has divested its 50 % ownership in RE Ventures I, LLC (the ENPP1 joint venture) to Recursion Pharmaceuticals for immediate and potential future consideration.
- Initial consideration: Recursion issued 1,457,952 Class A shares (VWAP $5.1442) valued at $7.5 million on 8 July 2025.
- Make-whole mechanism: If Rallybio’s net proceeds from selling the Initial Shares differ from $7.5 million, the party benefiting must true-up the difference in cash.
- Contingent equity: Upon achievement of specified development milestones for the ENPP1 compound, Rallybio may receive additional shares worth up to $12.5 million, with the same make-whole feature.
- Milestone & royalty stream: The agreement grants Rallybio undisclosed cash milestone payments and low-single-digit royalties on future net sales of ENPP1-related products.
- Following the sale, the ENPP1 JV becomes an indirect wholly-owned subsidiary of Recursion; Rallybio relinquishes all equity interest.
The transaction strengthens Rallybio’s liquidity with $7.5 million in equity that can be monetised, de-risks ongoing ENPP1 development costs, and leaves upside through contingent consideration and royalties. However, future value now depends on milestones achieved by Recursion, and Rallybio forgoes direct participation in the JV’s long-term upside.
