Creating a New Leader in Spine and Orthopedics

October 11, 2022

SeaSpine Distributors,

Today is an exciting day for Seaspine! This morning we announced an agreement to merge with Orthofix, creating a leading global spine and orthopedics company. See the joint Press Release here.

Orthofix is a global medical technology company with two strategic business units – Orthofix Spine and Orthofix Orthopedics—dedicated to developing, manufacturing, and distributing diverse product lines in more than 60 countries worldwide. They are the number #1 prescribed bone growth stimulator in the U.S., and the only company with a cervical indication, and you may have heard of their next generation differentiated artificial cervical disc which is a leader in the motion preservation segment.

Orthofix, like SeaSpine, is committed to improving patients’ lives and delivering innovative, quality-driven solutions that empower physicians and healthcare organizations to cost effectively meet the evolving clinical needs of their patients every day. It is clear we share not just common business goals, but a deep belief in our people, partners, and the patient lives’ that we improve.

Why Orthofix?

In short, we are confident Orthofix and SeaSpine are strong, committed partners. This combination brings together two highly compelling and complementary businesses to create new opportunities for our company – and for our sales and distributor partners around the globe.

What happens next?

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, SeaSpine and Orthofix will remain and continue to operate as separate companies. We must stay focused on executing against our current business objectives and strategy in day-to-day roles and responsibilities.

Leadership & Locations

Looking ahead to the closing, I am honored to share that I will become CEO of the combined company. Jon Serbousek, Director, President and CEO of Orthofix, will become Executive Chairman of the Board of the combined company. Additional leaders will be announced in the near future 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 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.

Thank You

On behalf of the entire leadership team, I thank you again for your partnership, and the continued opportunity to partner with you throughout this transition and in the future.

Stronger together,

KV

This report contains statements which, to the extent they are not statements of historical or present fact, constitute “forward-looking statements” under the securities laws. From time to time, oral or written forward-looking statements may also be included in other information released to the public. These forward-looking statements are intended to provide Orthofix’s and SeaSpine’s respective management’s current expectations or plans for our future operating and financial performance, based on assumptions currently believed to be valid. Forward-looking statements can be identified by the use of words such as “believe,” “expect,” “expectations,” “plans,” “strategy,” “prospects,” “estimate,” “project,” “target,” “anticipate,” “will,” “should,” “see,” “guidance,” “outlook,” “confident,” “on track” and other words of similar meaning. Forward-looking statements may include, among other things, statements relating to future sales, earnings, cash flow, results of operations, uses of cash, tax rates, R&D spend, other measures of financial performance, potential future plans, strategies or transactions, credit ratings and net indebtedness, other anticipated benefits of the proposed merger, including estimated synergies and cost savings resulting from the proposed merger, the expected timing of completion of the proposed merger, estimated costs associated with such transaction and other statements that are not historical facts. All forward-looking statements involve risks, uncertainties and other factors that may cause actual results to differ materially from those expressed or implied in the forward-looking statements. For those statements, we claim the protection of the safe harbor for forward-looking statements contained in the U.S. Private Securities Litigation Reform Act of 1995. Such risks, uncertainties and other factors include, without limitation: (1) the effect of economic conditions in the industries and markets in which Orthofix and SeaSpine operate in the U.S. and globally and any changes therein, including financial market conditions, fluctuations in commodity prices, interest rates and foreign currency exchange rates, and the levels of market demand in the health care segments in which our products are purchased and utilized; (2) challenges in the development, regulatory approval, commercialization, reimbursement, market acceptance, performance and realization of the anticipated benefits of new products of the combined company; (3) the scope, nature, impact or timing of the proposed merger, including among other things the integration of the businesses and realization of synergies and opportunities for growth and innovation and incurrence of related costs and expenses; (4) future levels of indebtedness, capital spending and research and development spending; (5) future availability of credit and factors that may affect such availability, including credit market conditions and our capital structure; (6) delays and disruption in delivery of materials and services from suppliers; (7) cost reduction efforts and restructuring costs and savings; (8) new business and investment opportunities; (9) the ability to realize the intended benefits of organizational changes; (10) the anticipated benefits of diversification and balance of operations across product lines, regions and industries; (11) the effect of changes in political conditions in the U.S. and other countries in which Orthofix, SeaSpine and the businesses of each operate, including the effect of changes in U.S. healthcare policies, on general market conditions in the near term and beyond; (12) the effect of changes in tax, regulatory and other laws and regulations in the U.S. and other countries in which Orthofix, SeaSpine and the businesses of each operate; (13) negative effects of the announcement or pendency of the proposed merger on the market price of Orthofix and/or SeaSpine’s respective common stock and/or on their respective financial performance; (14) the ability of the parties to receive the required regulatory approvals for the proposed merger (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the transaction) and approvals of Orthofix’s and SeaSpine’s shareholders and to satisfy the other conditions to the closing of the merger on a timely basis or at all; (15) the occurrence of events that may give rise to a right of one or both of the parties to terminate the merger agreement; (16) risks relating to the value of the Orthofix shares to be issued in the proposed merger, significant transaction costs and/or unknown liabilities; (17) the possibility that the anticipated benefits from the proposed merger cannot be realized in full or at all or may take longer to realize than expected, including risks associated with third party contracts containing consent and/or other provisions that may be triggered by the proposed transaction; (18) risks associated with transaction-related litigation; (19) the possibility that costs or difficulties related to the integration of Orthofix’s and SeaSpine’s operations will be greater than expected; (20) the ability of the combined company to retain and hire key personnel; (21) the intended qualification of the merger as a tax-free reorganization to Orthofix and SeaSpine shareholders for U.S. federal income tax purposes; and (22) the impact of the proposed merger on the respective businesses of Orthofix and SeaSpine. There can be no assurance that the proposed merger will in fact be consummated in the manner described or at all.
