ImmuCell Announces Financial Results for Third Quarter of 2007

PORTLAND, ME--(Marketwire - November 2, 2007) - ImmuCell Corporation (NASDAQ: ICCC) today announced the results of its operations for the three and nine month periods ended September 30, 2007.

For the three month period ended September 30, 2007, product sales decreased by 7%, or $76,000, to $983,000 in comparison to the same period in 2006. For the nine month period ended September 30, 2007, product sales increased by 1%, or $36,000, to $3,283,000 compared to the same period in 2006.

During the third quarter of 2007, ImmuCell announced that Pfizer Animal Health elected to terminate its product development and marketing agreement covering Mast Out® and return the product rights to ImmuCell. As a result of this termination, the Company recognized the remaining deferred income from non-refundable milestone payments received from Pfizer and wrote off the remaining unamortized cost of technology rights acquired in November 2004. This resulted in a net increase to income before income taxes of approximately $602,000 during the third quarter of 2007, with no impact on cash.

Including the impact of the accounting described above, the Company reported income before income taxes of $605,000 during the three month period ended September 30, 2007 in comparison to $291,000 during the same period in 2006. The Company recognized income before income taxes of $1,029,000 during the nine month period ended September 30, 2007 compared to $832,000 during the same period in 2006.

The Company reported net income of $354,000 ($0.12 per diluted share) during the three month period ended September 30, 2007 in comparison to $171,000 ($0.06 per diluted share) during the same period in 2006. The Company recognized net income of $590,000 ($0.19 per diluted share) during the nine month period ended September 30, 2007 compared to $492,000 ($0.16 per diluted share) during the same period in 2006.

"Sales of our lead product, First Defense®, increased by 3% during the first nine months of the year," said Michael F. Brigham, President and CEO. "Excluding non-cash amortization expense related to an intangible technology asset, product development expenses increased by 43%, or $78,000, during the third quarter of 2007 compared to the same period in 2006, principally reflecting our initial efforts to fund the development of Mast Out® internally."

Cash, cash equivalents and short-term investments decreased by 18%, or $1,186,000, to $5,428,000 at September 30, 2007 as compared to $6,614,000 at December 31, 2006. The decrease was largely due to an ongoing effort to become compliant with current Good Manufacturing Practices (cGMP) regulations. Shareholders' equity increased by 7%, or $630,000, to $9,962,000 at September 30, 2007 as compared to $9,332,000 at December 31, 2006. The Company had 2,892,000 shares of common stock outstanding as of September 30, 2007.
