The aggregate purchase price for the repurchase is approximately $181 million, which is expected to be funded from the Company’s existing cash and cash equivalents. The transactions are expected to close on October 15, 2025. In connection with the Purchase Agreements, Mr. Ran Nussbaum and Mr. Tomer Kariv have tendered their resignations to the Board of Directors, effective immediately.

In connection with its entry into the Purchase Agreements, Keros also reported that it plans to distribute 25% of any net cash proceeds it receives on or before December 31, 2028 from its global license agreement with Takeda Pharmaceuticals U.S.A., Inc. ("Takeda") to Keros stockholders.

Following the closing of the transactions with ADAR1 and Pontifax, the Company intends to commence a tender offer for up to $194 million in value of shares of the Company’s common stock, subject to market conditions, at a purchase price of $17.75 per share in cash. The Company presently intends to commence the tender offer by the end of October 2025. The Company expects to fund the tender offer from its existing cash and cash equivalents.

"We are pleased to have reached these agreements with ADAR1 and Pontifax, and look forward to completing our capital return program in the near term. The capital return program – which includes an additional commitment to distribute future near-term Takeda proceeds – reflects our confidence in the outlook for Keros and the prospects for our key clinical program, KER-065," said Jean-Jacques Bienaimé, Chair of the Board of Directors. "With a more focused and streamlined organization, supported by a strong financial position, we are moving forward fully focused on the execution of our clinical strategy. We continue to target a first quarter 2026 start of the Phase 2 clinical trial of KER-065 in patients with Duchenne muscular dystrophy ("DMD"), subject to positive regulatory interaction, and believe Keros is well-positioned to deliver meaningful value to both patients and stockholders."

"Our engagement with the management team and Board has delivered results for all stockholders, including a commitment by Keros to return a portion of the Takeda licensing revenue directly to investors," said Daniel Schneeberger, Founder and Chief Investment Officer at ADAR1 Capital Management. "We appreciate the collaborative dialogue we have had with the Company and believe today’s announcement is a thoughtful and positive step toward enhancing long-term stockholder value."

The negotiation and approval of the repurchase transactions with ADAR1 and Pontifax were overseen by a Capital Return Committee of Keros’ Board of Directors, composed entirely of independent and disinterested directors. The Committee recommended that the full Board approve the repurchase transactions and the subsequent tender offer, which the Board approved.

The Purchase Agreements include certain customary standstill, voting and other provisions. Details of the Purchase Agreements will be filed on a Form 8-K with the U.S. Securities and Exchange Commission (the "SEC").

Goldman Sachs & Co. LLC is serving as Keros’ financial advisor, and Cooley LLP is serving as legal counsel.

The proceeds from the Series C financing will be used to expand the clinical development of TUB-040, Tubulis’ lead antibody-drug conjugate (ADC) candidate, into earlier lines of therapy and additional tumor indications. TUB-040 targets NaPi2b, an antigen that is overexpressed in ovarian cancer and lung adenocarcinomas. TUB-040 is currently being evaluated in a Phase I/IIa study (NAPISTAR1-01, NCT06303505) in patients with platinum-resistant ovarian cancer (PROC) as well as relapsed or refractory non-small cell lung cancer and was granted Fast Track designation by the U.S. FDA in June 2024. The capital will also advance Tubulis’ pipeline, including the clinical-stage ADC candidate TUB-030, several preclinical programs, and expand its proprietary ADC platform technologies to bring ADCs into novel applications.

"This landmark financing round reflects the deep conviction these global healthcare investors have in Tubulis and the disruptive potential of our ADC platforms," said Dr. Dominik Schumacher, CEO and Co-founder of Tubulis. "With TUB-040 progressing in the clinic and first data to be shared in a late-breaking oral presentation at ESMO (Free ESMO Whitepaper), we are ready to expand into earlier treatment lines, while continuing to innovate across our pipeline and technology platforms. The new funding empowers us to execute on our vision of creating truly differentiated antibody-drug conjugates that are tailored to the biology of solid tumors and can deliver superior therapeutic value to patients."

"Tubulis has distinguished itself in the ADC field with a forward-looking vision consistently backed by strong scientific data," said Nimish Shah, Partner at Venrock Healthcare Capital Partners. "The company is now positioned to translate an exceptional preclinical foundation into meaningful clinical results, with several important readouts on the horizon. As Tubulis continues to expand its pipeline and build momentum, I’m excited to partner with the leadership team and Board to advance a new generation of ADC medicines for patients."

In conjunction with the financing, Dr. Lorence Kim, Co-founder and Managing Partner at Ascenta Capital and Patrick Heron, Managing Partner at Frazier Life Sciences, will join Tubulis’ Supervisory Board. An overview of all Supervisory Board members and their biographies can be found here.

"This milestone financing is a testament to the scientific strength and executional track-record of the Tubulis team," added Dr. Christian Grøndahl, Chair of the Supervisory Board of Tubulis. "The company has built a unique ADC platform and is now working on demonstrating its clinical impact. With the backing of experienced biotech investors, Tubulis is on a path towards solidifying its position as a global leader in the ADC landscape."

On October 14, 2025 NuCana plc (NASDAQ: NCNA) ("NuCana" or the "Company") reported the publication of new data on NUC-3373. The update includes results from the NuTide:303 clinical study, published on medRxiv, the preprint server for health sciences, together with complementary preclinical findings published in the peer-reviewed journal Public Library of Science ONE (PLOS ONE).

NUC-3373, a potent thymidylate synthase inhibitor that induces DNA damage in cancer cells, has previously shown encouraging activity in combination with the PD-1 inhibitor pembrolizumab in the Phase 1/2b modular study, NuTide:303. In Module 1 of this study, 12 patients with advanced solid tumors who had exhausted all standard treatment options and had previously received PD-1 inhibitors were treated with NUC-3373 plus pembrolizumab.

Encouraging signals of durable activity were observed, including:

A 100% reduction in tumor lesion size (classified as a partial response due to the presence of non-target lesions) in a patient with urothelial carcinoma of the bladder who remained on treatment for over 15 months; and

An 81% reduction in target lesions in a patient with metastatic melanoma resistant to prior pembrolizumab therapy, who continues to remain progression-free at 23 months.

These promising clinical findings are further supported by preclinical data. The published results demonstrate that NUC-3373 in a model in vitro system:

Promotes the release of immunogenic damage-associated molecular patterns (DAMPs);

Enhances activation of first-line defense immune cells, including natural killer (NK) cells; and

In combination with a PD-1 inhibitor, enhances tumor cell death by activating lymphocytes, regardless of the tumor’s genomic stability status.

"It is becoming increasingly clear that the majority of future standards of care for advanced cancers will rely on combination regimens incorporating novel immuno-oncology backbones," said Professor David Harrison, Head of Translational Medicine at NuCana. "The combination of NUC-3373 with pembrolizumab has demonstrated both a favorable safety profile and evidence of efficacy and durable disease control in this patient cohort."

Andrew Kay, NuCana’s Executive Chairman, added: "The complementary mechanisms of action of NUC-3373 and PD-1 inhibition provide a strong rationale for synergy. We are currently evaluating optimal combinations and indications for further clinical studies of NUC-3373, while continuing to maintain our anticipated cash runway into 2029. We are committed to advancing these assets and working toward our vision of delivering significantly improved treatment outcomes for patients with cancer."
