Cyclerion Announces Definitive Agreement for Zagociguat and CY3018

Certain Cyclerion shareholders and new investors have agreed to invest $81M to launch a new company targeting diseases of mitochondrial dysfunction

Cyclerion to receive $8M in cash and 10% equity in the new company in exchange for its zagociguat and CY3018 assets

Definitive agreement signing triggers previously announced $5M equity investment in Cyclerion

CAMBRIDGE, Mass., May 11, 2023 — Cyclerion Therapeutics, Inc. (Nasdaq: CYCN) announced today that it has signed a definitive agreement with a new private company (“NewCo”) to sell two of its sGC stimulator assets in exchange for cash and equity ownership. Investors in NewCo have agreed to invest $81M to develop zagociguat (previously CY6463) to treat MELAS* and other diseases associated with mitochondrial dysfunction and advance CY3018.

Under the terms of the asset purchase agreement, Cyclerion will receive an $8M cash payment at closing, reimbursement for all expenses related to zagociguat and CY3018 for the period between the signing and closing of the transaction, and 10% equity ownership in NewCo that is subject to anti-dilution protection through $100M in post-money valuation.  Cyclerion will also have additional future equity purchase rights in NewCo. Current Cyclerion shareholders including Invus and CEO Peter Hecht are participating in the capitalization of NewCo. They are joined in the NewCo investor syndicate by Venrock, J Wood Capital and Sanofi Ventures.  The transaction is subject to approval by Cyclerion shareholders. Each of the current Cyclerion investors who are participating in the NewCo capitalization have agreed to vote their Cyclerion shares in favor of the transaction.  Following the closing, NewCo will be solely responsible for all activities and expenses related to developing and commercializing zagociguat and CY3018.

Signing of the definitive agreement triggered the previously announced $5M equity investment by CEO Peter Hecht. This investment will take place on May 19, 2023, and Hecht will receive a mix of common stock and nonvoting convertible preferred stock of Cyclerion at a minimum purchase price of $0.434 per share, subject to adjustment for any reverse stock split or similar event.

“We are pleased to see our zagociguat and CY3018 assets attracting the capital and capabilities they will need to continue their development in mitochondrial and CNS diseases.  Over the past 12 months, our board, management and advisors have carried out an exhaustive and thorough process to evaluate all available opportunities to maximize the value of our assets for our shareholders in this exceptionally challenging capital market while advancing potentially life-changing medicines to patients,” said Errol De Souza, Chair of the Board at Cyclerion “With this transaction, we believe these compounds will receive the focus they deserve, and Cyclerion shareholders will be able to benefit from future value creation via Cyclerion’s equity position in the new company without any go-forward operational or financial obligations for these programs."

Stifel is acting as financial advisor to Cyclerion; Hughes Hubbard & Reed LLP is serving as legal counsel to the Board and the Company.

About Cyclerion Therapeutics

Cyclerion Therapeutics is a clinical-stage biopharmaceutical company on a mission to develop treatments for serious diseases.

Exhibit 99.2

Cyclerion Announces Corporate Updates and Q1 2023 Financial Results

Definitive agreement reached with new company (“NewCo”) established by certain Cyclerion shareholders and new investors

Cyclerion to receive $8M in cash and 10% equity in NewCo in exchange for its zagociguat and CY3018 assets

Definitive agreement signing triggers previously announced $5M equity investment in Cyclerion

Cyclerion CEO Peter Hecht Ph.D. to lead NewCo while continuing to serve on the Cyclerion board as one of the company’s largest shareholders

Biopharma executive Errol De Souza Ph.D. elected as chair of the Cyclerion board

CAMBRIDGE, Mass., May 11, 2023 — Cyclerion Therapeutics, Inc. (Nasdaq: CYCN) today announced corporate updates and first quarter 2023 financial results.

Definitive Agreement Signed

On May 11, 2023 Cyclerion entered into a definitive agreement to sell two of its sGC* stimulator assets, zagociguat (formerly CY6463) and CY3018, to a new private company (“NewCo”) formed by certain current Cyclerion shareholders and new investors who have agreed to invest $81M to advance these assets. Under the terms of the agreement, Cyclerion will receive an $8M cash payment at closing, reimbursement for all expenses related to zagociguat and CY3018 for the period between signing and closing of the transaction, and 10% equity ownership in NewCo that is subject to anti-dilution protection through $100M in post-money valuation.  Cyclerion will also have additional future equity purchase rights in NewCo.  The transaction is subject to approval by Cyclerion shareholders and, once completed, will enable the assets to be developed in NewCo with the capital and capabilities to advance them while giving Cyclerion shareholders the opportunity to participate in future value creation without having the obligation to make direct investments and take on the risk of these early-stage programs.

Go Forward Strategy

Previously, Cyclerion out-licensed the peripherally active sGC stimulator praliciguat to Akebia Therapeutics, Inc. (“Akebia”), a leading biopharmaceutical company focused on kidney disease. Under the terms of that agreement, the Company is eligible to receive up to $585M in development, regulatory, and commercialization milestones, as well as sales-based royalties. Cyclerion retains full rights to olinciguat, an oral, once-daily, peripheral sGC stimulator, that has shown a favorable safety and tolerability profile, drug characteristics, and dose-dependent pharmacological activity in several placebo controlled clinical studies.  Olinciguat has a strong patent estate with intellectual property exclusivity to the late 2030s.  sGC stimulators are now approved for PAH** and HFrEF*** (both multibillion dollar opportunities).  In similar fashion to today’s transaction and the Akebia license, Cyclerion intends to identify a partner with deep cardiovascular experience to maximize olinciguat’s value while minimizing distraction and operating expense.

These external development deals make up a growing diverse portfolio of upside value for our shareholders and the potential for non-dilutive funds from upfront and milestone payments and/or monetization of equity positions and royalties. The externalization of the initial sGC assets means that Cyclerion now has the opportunity to bring in new assets to develop using its highly efficient and externalized model. The Company will initially target assets in the CNS therapeutic area that are at a later stage of development and can be advanced to approval more quickly.

Upon approval of the current transaction by Cyclerion shareholders, Peter Hecht will transition out of his Cyclerion CEO role and join NewCo as its CEO. Dr. Hecht, a major Cyclerion shareholder, will continue to serve as a Cyclerion Director.  Cyclerion has initiated a search to bring in a new leader to drive the company’s strategy going forward.

Board of Directors

Current independent board member Errol De Souza has been elected to serve as the chair of the Cyclerion Board effective immediately. Dr. De Souza is a seasoned R&D and business leader with broad experience - from large pharma to start ups - in the discovery and development of therapeutics for the treatment of CNS disorders.

“I am excited to have a unique platform from which to exercise my passion for finding underappreciated and undervalued neuro assets.  I’ve been fortunate to have had multiple successful opportunities to uncover important neuro therapies through approval that are having profound impacts on patients’ lives, and I’ve done so in a variety of circumstances, including small biotechs” said Errol De Souza, Chair of the Cyclerion Board of Directors. “I am looking forward to the opportunity to take learnings from each of those and apply them to Cyclerion alongside a group of supportive, long-term, core investors.”

ADv Study Results

Cyclerion recently completed the analysis of its signal-seeking clinical study of zagociguat for the potential treatment of Alzheimer’s disease with vascular pathology (ADv) (NCT04798989). This exploratory, randomized, placebo-controlled, study of oral once-daily zagociguat was designed to evaluate safety, tolerability, and pharmacokinetics as well as explore the impact on biomarkers and cognitive performance over a twelve-week dosing period. The total number of participants in the study was capped at 12 participants due to challenges associated with enrollment. Data from this study show that the safety and tolerability profile of once-daily zagociguat was consistent with prior studies. Given the small number of participants Cyclerion is unable to draw any conclusions from the data generated in the study.

Equity Investment

Signing of the definitive agreement today triggered the previously announced $5M equity investment by CEO Peter Hecht. This investment will take place on May 19, 2023 and Hecht will receive a mix of common stock and nonvoting convertible preferred stock of Cyclerion at a minimum purchase price of $0.434 per share, subject to adjustment for any reverse stock split or similar event.  The proceeds from this investment and the $8M upfront from the sale of zagociguat and CY3018 are expected to support ongoing operations for at least 12 months post-closing of the transaction.
