The Company anticipates a start date of November 1, 2025 for Mr. te Boekhorst.

Mr. te Boekhorst is currently an Operating Partner at ARCHIMED, a global investment firm focused on human and animal healthcare industries, and serves as Chair of the Board of SeqCenter, a Next Generation Sequencing laboratory located in Pittsburgh, PA, where he previously served as CEO.

At IDEXX, Mr. te Boekhorst led M&A activities consolidating the livestock diagnostics segment, and as Senior VP he grew the livestock and dairy diagnostics, water safety testing, and human diagnostics divisions. He launched and grew multiple innovations for dairy and beef producers worldwide to drive customer and shareholder value. Early in his career, Mr. te Boekhorst worked for the Boston Consulting Group and received an MBA from Cornell University.

"Change is good, and handing off leadership to Olivier at this time is an exciting next step for the Company," said Michael F. Brigham, the Company's current President and CEO. "Olivier brings to the Company a depth of experience and industry contacts that we expect will be very valuable as we work to grow First Defense^® sales with our increased production capacity now successfully in place, and progress next steps for Re-Tain^®."

"I am excited to join the ImmuCell organization as President and CEO at this pivotal time, with exciting opportunities for First Defense^® and Re-Tain^® ahead of us," commented Mr. te Boekhorst. "ImmuCell has a unique opportunity to improve farm animal welfare and contribute to the sustainability of the dairy and beef industries by offering solutions that address scours and mastitis without traditional antibiotics. I am impressed with the ImmuCell team, and I look forward to working with them to create value for customers and stockholders."

After Mr. te Boekhorst's start date, Mr. Brigham will serve as Special Advisor to the CEO for at least two months, to help assure a smooth transition. Mr. Brigham also will continue to serve on the Company's Board of Directors until the next Annual Meeting of Stockholders and looks forward to continued Board service thereafter subject to re-election by stockholders.

The terms of Mr. te Boekhorst's employment include two initial awards of stock options as inducement grants under terms approved by Company's Compensation and Stock Option Committee. The first award was a non-qualified stock option to purchase 76,673 shares of common stock of the Company, granted on September 16, 2025. That award will terminate and never become exercisable unless Mr. te Boekhorst commences employment with the Company by November 30, 2025 at the latest. The second award (for up to an additional 85,000 shares, subject to adjustment) is to be made through a grant after commencement of employment and will consist of a mix of incentive stock options and non-qualified stock options. All of these stock options will carry a 10-year term from the date of grant. Each grant will vest in three equal increments, on the first, second, and third anniversaries of their respective dates of grant. The options granted September 16, 2025 have a stated exercise price of $5.90 per share. The options to be granted after commencement of employment will have a stated exercise price equal to the closing price of the Company's common stock on the date of grant.
