NOTICE OF CHANGE TO VIRTUAL MEETING FORMAT FOR THE
ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON JUNE 2, 2021
To our stockholders:
In response to the continued public health concerns regarding in-person gatherings as a result of the ongoing COVID-19 pandemic and to continue to support the health and well-being of its stockholders, directors, and employees, NOTICE IS HEREBY GIVEN that the format of the 2021 annual meeting of stockholders of SeaSpine Holdings Corporation (the "Company") has been changed to a meeting conducted in a virtual-only format, solely by means of remote communication, instead of an in-person meeting. The annual meeting will continue be held on Wednesday, June 2, 2021 at 7:00 a.m. Pacific Time. However, it will no longer be held at the Company’s principal executive offices located at 5770 Armada Drive, Carlsbad, California 92008, but instead will be held virtually, with attendance only via the internet. Stockholders will not be able to attend the annual meeting in person.
As described in the previously-distributed proxy materials for the annual meeting, you are entitled to vote at the annual meeting if you held shares of the Company’s common stock as of the close of business on April 5, 2021, the record date for the annual meeting. The items of business to be presented at the annual meeting are the same as set forth in the Company's Notice of 2021 Annual Meeting of Stockholders and Proxy Statement dated April 21, 2021 previously mailed or made available to stockholders entitled to notice of and to vote at the annual meeting. The proxy card, voting instruction form or notice of internet availability included with your previously-distributed proxy materials will not be updated to reflect the change in format of the meeting.

We encourage you to access the meeting in advance of the designated start time.
Voting Prior to or During the Annual Meeting. You may vote prior to the annual meeting via the original proxy card or pursuant to the instructions for submitting your proxy via the internet or telephone that were included in the previously-distributed proxy materials.
