For Immediate Release

PORTLAND, Maine – May 14, 2025 – ImmuCell Corporation (Nasdaq: ICCC) (“ImmuCell” or the “Company”), a growing animal health company that develops, manufactures and markets scientifically proven and practical products that improve the health and productivity of dairy and beef cattle, today announced its unaudited financial results for the quarter ended March 31, 2025.

Product Sales Highlights:

Preliminary, unaudited product sales for the first quarter of 2025 were first reported on April 8, 2025. There are no changes to those figures.

Management’s Discussion:

“Product sales during the first quarter of 2025 of $8.1 million set a record high for us, beating the previous record set during the fourth quarter of 2024,” commented Michael F. Brigham, President and CEO of ImmuCell. “We also set a quarterly record for net income, which totaled approximately $1.4 million, beating the previous record of $584,000 set during the first quarter of 2017.”

“As we continue to manufacture at our new, higher level of production output, we are working to reduce the backlog of orders and improve our gross margin,” continued Mr. Brigham. “The 42% gross margin recorded during the first quarter of 2025 represented an improvement over the gross margin of 37% recorded during fourth quarter of 2024.”

“As our contract manufacturer continues to work to resolve inspectional observations at their facilities, we are moving ahead with Investigational Product use of Re-Tain® to collect market feedback about product performance in the field over the second half of 2025,” concluded Mr. Brigham. “At the same time, we are reducing product development expenses and exploring potential strategic options for our technology.”

Non-GAAP Financial Measures:

Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position or cash flow that either excludes or includes amounts that are not normally included in or excluded from the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP measures included in this press release should be considered in addition to, and not as a substitute for or superior to, the comparable measure prepared in accordance with GAAP. We believe that considering the non-GAAP measure of Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) assists management and investors by looking at our performance across reporting periods on a consistent basis excluding certain charges from our reported net income (loss). Adjusted EBITDA is calculated and reconciled to the most comparable GAAP financial measure in the following table:

Cash payments to satisfy debt repayment obligations and to make capital expenditure investments are other uses of cash that are not included in the calculation of EBITDA, which management also considers when assessing its cash flows.
