The acquisition has successfully closed and OneOncology is now a part of Cencora effective February 2, 2026. While we officially joined the Cencora family on February 2, 2026, any integration activities will be evaluated, determined, and communicated over time.

Cencora has maintained a longstanding partnership with OneOncology, and this transaction enables us to enhance our support for community-based specialty care. This collaboration is consistent with our strategy, as providers increasingly seek partners who can manage operational complexities while upholding physician autonomy and prioritizing patient care. Through our relationship with Cencora, we are positioned to more effectively serve independent oncology and urology physicians, improve the provider experience, and support improved patient outcomes and access to care.

A joint Integration team made up of key personnel from both OneOncology and Cencora is leading a thoughtful, deliberate integration of OneOncology into Cencora. The team will centrally coordinate integration direction and planning, partnering with leaders across OneOncology to execute functional, commercial, and cross-functional workstreams in a way that preserves what is already working and enhances OneOncology capabilities only where it adds clear value as OneOncology continues to scale through ongoing practice growth.

Jason Dinger, President, MSO will oversee Cencora’s MSO strategy and businesses. Together Jason and Dr. Jeff Patton, CEO of OneOncology, will work to drive growth and new opportunities for our combined organizations.

OneOncology will continue to operate with a physician-centric model—that is core to its value and success. The goal of this partnership is not to change what makes OneOncology unique, but to protect and strengthen the physician-first culture that already exists. OneOncology MSO employees are central to the success of this partnership, and stability is a priority. In the near term, nothing changes in day-to-day operations. Teams will operate as they do today.

The integration process will focus on aligning systems, processes, and teams where appropriate, with an emphasis on a strong partnership between OneOncology and Cencora. You can expect open communication, support, and collaboration, and we will share regular updates so you understand how any changes may impact your work.

For now, our ask to everyone is to continue focusing on what you’ve always done – executing and delivering exceptional care and support for your team members, physicians and patients. We will be operating business as usual for the foreseeable future and will share updates throughout the integration process as they are solidified.

Similar to OneOncology, Cencora shares aligned values that are focused on creating healthier outcomes.

We don’t take our position in the center of healthcare lightly – it is a privilege and a responsibility that fuels our commitment to excellence. It also propels us to always seek and define what’s next. Our focus on a growth mindset and innovation was something we also saw across OneOncology, and together we look forward to what we can accomplish in the year(s) ahead.

OneOncology is joining Cencora, an organization committed to our purpose: We are united in our responsibility to create healthier futures. Our enterprise purpose is what fuels our 51,000+ team members around the globe—because we understand the importance and significance of what we do every day and the impact that it has on patients, animals and communities around the world.

For decades, Cencora has maintained a focus on the growth of our specialty business and a commitment to ensuring the vitality of specialty care in local communities.

Following the acquisition of Retina Consultants of America in 2025, Cencora’s investment in OneOncology is a natural step forward allowing us to continue our focus on specialty care, offering physicians the services and solutions they need to effectively manage their practices.

We will be operating business as usual for the foreseeable future. Any changes to systems or workflows that may occur as we integrate will enhance the care you provide, and physician leaders will have a voice in shaping our future state. We will share regular updates as this work progresses.

No. There are currently no plans to change the OneOncology or practice branding at this time.

We will work with the OneOncology and Cencora leadership teams to provide regular and consistent updates so you can learn more about Cencora through your existing communication channels. In the meantime, if you’d like to learn more, you can visit our website at: www.cencora.com

You can also visit our LinkedIn page for more regular updates about events, thought leadership, and milestones across the company: www.linkedin.com/company/cencoraglobal

There are no anticipated changes to salary, benefits, or retirement savings plans at this time.

Yes. You will continue to use Workday as your HR system, and nothing is changing at this time. This partnership will enable us to identify opportunities to enhance HR capabilities and systems in the future.

There are no planned reductions due to the acquisition. It is the intention of Cencora to grow the business.

Yes — there are no plans at this time to change email addresses or replace laptops. We will continue operating business as usual for the foreseeable future.

Cencora’s vision for OneOncology is to grow together over time through a long-term MSO strategy focused on strengthening community-based specialty care. As Cencora’s MSO platform is still new, we see this as an evolution, one where we bring enterprise scale, capabilities, and operational support, while also learning from OneOncology’s experience and leadership in physician-led oncology care.

Cencora’s goal is to support OneOncology in a way that preserves clinical independence, strengthens practice sustainability, expands access and innovation in community settings, and helps build a more connected, scalable, and resilient model for the future. In short, this is a long-term partnership centered on mutual learning, physician autonomy, and better patient care.

At this time, there are no immediate changes to employees’ day-to-day work. The expectation is to continue business as usual and stay focused on delivering exceptional care and support to team members, physicians, and patients. There are no planned changes to current roles, responsibilities, workflows, or reporting structures.

OneOncology is joining Cencora because the organizations share aligned values, including a commitment to healthier outcomes, excellence, innovation, and a growth mindset. Together, we can better serve independent oncology and urology physicians by helping address the growing complexity of running a practice while preserving clinical autonomy and a patient-first approach. Building on OneOncology’s strong growth in recent years, this combination will enhance the provider experience and help improve patient outcomes and access to care.

Additional partnership updates and how OneOncology, Cencora, and affiliated entities fit together will be shared as they become available here on our partnership microsite.

At this time there are no planned changes to jobs or reporting structures. What we shared in February remains true: Cencora’s intention is to grow the business, not reduce it.

At this time, no changes to systems, IT, training, or integration processes have been finalized. OneOncology and Cencora teams are working together to assess potential improvements as part of the discovery process, which is expected to continue through the summer. Updates will be shared as they become available.

We’ve heard the feedback and are taking steps to improve communication and transparency. Over the summer, in addition to this partnership microsite, the team will begin sharing a quarterly newsletter with updates. The microsite will be kept up to date with the latest need-to-know information, and employees are encouraged to bookmark it for easy access.

Cencora brings the potential for greater scale, broader capabilities, and additional resources to support employees, practices, and patients over time. We are still in the early stages of identifying and realizing the full synergies and opportunities of the partnership, but we are confident that meaningful benefits will take shape over time, including stronger support for practices, enhanced capabilities and tools, shared best practices, and ultimately a positive impact for patients. Team members are encouraged to continue sharing questions through the microsite at any time.
