Exciting News: Creating a New Leader in Spine and Orthopedics

October 11, 2022

Today is an exciting day for our company! This morning we announced an agreement to merge with SeaSpine, creating a leading global spine and orthopedics company.

SeaSpine is a global medical technology company focused on surgical solutions for the treatment of spinal disorders. You may be familiar with their Flash™ Navigation System with 7D technology and biologics solutions, among other cutting-edge technologies. I have spent a great deal of time with the SeaSpine team in the weeks leading up to this announcement, and it is clear that we share not just common business views, but a deep belief in our people.

So, why SeaSpine?

In short, we are confident Orthofix and SeaSpine are terrific partners. This combination brings together two highly complementary businesses to create new opportunities for both companies – and for our collective teams.

Indeed, with the impressive capabilities from both organizations, we can reach new heights of innovation and market leadership greater than either company could achieve on its own.

What happens next?

It is important to recognize that our announcement today is just the first step toward officially joining with SeaSpine.

We expect the transaction to close in the first quarter of 2023, following approval by both companies’ shareholders and customary closing conditions and regulatory approvals. Until then, Orthofix and SeaSpine remain separate companies, operating independently and as usual; there will be no negative impact to compensation and benefit plans. We must stay focused on executing against Orthofix’s current business objectives and day-to-day roles and responsibilities.

In the coming weeks, we will form teams to develop plans around how best to bring our companies together. These teams will include representatives from both companies. We are committed to ensuring a seamless integration after closing and will keep you updated as this planning progresses.

Leadership & Headquarters

I am honored to share that, upon closing, I will serve as Executive Chairman of the new combined company’s Board of Directors.

Keith Valentine, President and Chief Executive Officer of SeaSpine, will become President and CEO and Director on the Board of the combined company. Keith is an industry veteran, having worked in spine medtech for almost three decades, including at NuVasive, ORATEC Interventions and Medtronic. He has an outstanding record of driving innovation and a deep appreciation for teamwork – both within the company and in partnership with surgeons.

As Executive Chairman of the Board of Directors, I look forward to working closely with Keith to help guide the combined company’s strategy and its execution in the years ahead.

Additional members of our combined Board and leadership team will be announced at a later time and are expected to reflect talent from both organizations.

The combined company will be headquartered in Lewisville, Texas. This location will conduct general business, product development, medical education and manufacturing. The combined company will retain primary offices in Carlsbad, CA, with a focus on spinal product innovation and surgeon education, and in Verona, Italy with an emphasis on product innovation, production, and medical education for Orthopedics. Current facilities in Irvine, CA, Toronto, Canada, Sunnyvale, CA, Wayne, PA, Olive Branch, MS, Maidenhead UK, Munich, Germany, Paris, France and Sao Paulo, Brazil will also be retained.

Town Hall & Additional Information

I look forward to talking more about our merger at a Town Hall at 9:00 a.m. CT today. A meeting invite will follow shortly.

In the meantime, attached to this email is an infographic discussing the combination and an FAQ to address initial questions.

Thank You

It is due to our employees’ many contributions that we are able to take this step from a position of strength. On behalf of the entire leadership team, I thank you again for your dedication to our vision and mission and for continuing to help propel our success with SeaSpine after our merger closes.

Sincerely,

Jon Serbousek

Combination with SeaSpine – Message from Kevin Kenny

October 11, 2022

Team:

We made a significant positive announcement today about the future of our organization. I am very excited about our merger with SeaSpine and the opportunities it creates for the Company overall and our Spine Business Unit.

This combination will enable us to improve more patient lives and provide additional surgeon and hospital partners broader procedural solutions with cutting-edge technology. The two organizations product lines are highly complementary, and together we will have a leading spine offering and one of the broadest biologics portfolios available.

The Bone Growth Therapy business has been such an important aspect of Orthofix’s history, growth, and profitability. You should know that BGT will remain a key component of our growth plan in the new company as well. Indeed, we expect to use the financial strength and flexibility we will have after the merger closes to invest in BGT and build upon our leadership. Given the breadth and complementary nature of the Orthofix and SeaSpine portfolios, of which BGT is a significant part, we see tremendous opportunities for cross-selling across product lines, surgeon relationships and geographies in both the spine and global orthopedics channels.

In short, this merger creates significant upside for the Company and for the Spine Business Unit. However, we will not officially join with SeaSpine in the near term. The transaction is not expected to close until the first half of 2023. So, while it is good for us all to be excited, it is essential to stay focused and execute with a mindset of business as usual. We must continue to operate as independent organizations and to execute on our commercial initiatives and product innovation strategy focused on collaboration with surgeons and innovation.

I will continue to keep you updated as we progress on merger milestones in the coming months. In the meantime, thank you for your dedication and hard work in helping to drive Orthofix’s success.

Sincerely,

/s/ Kevin Kenny
