Commenting on the annual results, Robert Lyne, Chief Executive Officer of PureTech, said:
“2025 was a year of continued progress for PureTech, as we built on the strength of our portfolio and took important steps to sharpen our strategic focus. We have refined how we deploy capital and scale our programs, with an emphasis on advancing therapeutic candidates through key value-inflection points and leveraging external investment to support later-stage development. This approach enables us to operate with greater discipline and efficiency while maintaining meaningful long-term exposure to the value we create.
“Alongside these efforts, we have continued to advance our portfolio. During the year, we advanced deupirfenidone to Phase 3 readiness in idiopathic pulmonary fibrosis through our Founded Entity Celea Therapeutics (Celea). I’m pleased to note that Celea has secured sufficient non-binding commitments from external investors, in addition to participation from PureTech, such that the fundraising is substantially complete, subject to continued negotiations. Whilst mindful of macro factors, Celea is targeting to close the financing by early in the third quarter of 2026. The financing is intended to support the Phase 3 SURPASS-IPF trial, which Celea expects to commence in close proximity to closing the financing.
“We also reported positive clinical results from LYT-200 in relapsed/refractory myeloid malignancies and, with these data in hand, intend to pursue external financing for Gallop Oncology to support its next phase of development, with an initial focus on relapsed/refractory high-risk myelodysplastic syndrome. Additionally, Seaport Therapeutics continued to advance its neuropsychiatric pipeline, including encouraging initial results from one of two ongoing clinical trials initiated in 2025, and filed a registration statement with the United States Securities and Exchange Commission for a potential initial public offering, though the timing, number of shares to be offered, and the price range for the offering has not yet been determined.
“We are also focused on ensuring that the value we create is more clearly reflected for shareholders. Our model has historically generated meaningful returns through a combination of equity ownership and non-dilutive economics, and we believe our continued progress positions us to deliver this more consistently over time. Critically, following the completion of Celea's financing, we expect to reduce our operational burn significantly compared to our historical run rate, with a lower and more predictable cost base going forward. This will be driven in part by the transition of the Celea team and related development activities into the externally funded Founded Entity, reducing operating costs at the PureTech hub.
“As part of this broader focus on efficiency and alignment, we have announced our intention to voluntarily delist our American Depositary Shares from Nasdaq and concentrate our listing on the London Stock Exchange, where the substantial majority of trading volume and liquidity in our shares has consistently occurred. We believe this step simplifies our structure and reduces cost and administrative burden for the business, whilst retaining our primary London listing, providing access to both the UK and global investment community.
“Together, these actions are intended to create a leaner, more focused business. As part of this approach, we will look to return a greater proportion of future cash generation to shareholders, particularly in the event of any outsized returns, whilst maintaining appropriate operational runway.
“Looking ahead, our priorities remain clear. We are focused on advancing our most promising programs with urgency and discipline. At the same time, we will continue to invest in our innovation engine to generate the next wave of Founded Entities, while maintaining a thoughtful approach to capital allocation.
“PureTech was founded on the belief that innovative science and disciplined capital allocation can work hand in hand to deliver meaningful impact. As we move forward with greater focus and clarity, we believe we are well positioned to translate that approach into sustained value for both patients and shareholders.”

Letter from the Chair
Strengthening Our Foundation for Sustainable Value Creation
With a refreshed strategic focus, we have sharpened our hub-and-spoke model to more effectively advance differentiated programs through our Founded Entities, while cultivating the next wave of innovation with increased discipline.
2025 marked a defining year for PureTech, as we sharpened our strategic focus, strengthened our leadership, and positioned the Company for a new phase of disciplined value creation. Building on more than two decades of translating breakthrough science into value, we have taken important steps to align our model, portfolio, and governance with the opportunities ahead.
At the core of this progress is a renewed clarity around our differentiated hub-and-spoke model. By advancing programs through our Founded Entities, we are enhancing capital efficiency, reducing risk concentration, and accelerating paths to value realization. This approach reflects a more disciplined approach to portfolio management while preserving the scientific ambition that has long defined PureTech.
A key milestone in the year was the appointment of Robert Lyne as Chief Executive Officer in December 2025, following his tenure as Interim CEO. After a thorough and deliberate process, the Board unanimously concluded that Rob is the right leader to guide PureTech through this next phase. His deep understanding of our model, combined with a strong track record of aligning scientific innovation with disciplined execution, positions the Company to deliver on its strategic priorities with clarity and focus.
Under Rob’s leadership, we are sharpening operational execution across the portfolio while maintaining our capital-efficient approach. During the year, we continued to advance key programs and support our Founded Entities in attracting external capital, reinforcing the strength and scalability of our model. These efforts underscore our ability to translate scientific insight into meaningful progress for patients while creating long-term value for shareholders.
