BIO-key® Reports Fourth Quarter and Full Year 2009 Financial Results

WALL, N.J., March 25 /PRNewswire-FirstCall/ BIO-key International, Inc. (OTC Bulletin Board: BKYI), a leader in biometric identification solutions, today reported selected financial results for the fourth quarter and full year ended December 31, 2009. These results reflect the sale of its Law Enforcement Division, which was completed on December 8, 2009. For clarity and consistency, the data presented in this press release includes the results of the Company’s fingerprint-based Biometrics Division for the fourth quarter and the full year, with the Law Enforcement Division presented as discontinued operations.

Fourth Quarter Revenue and Income

Revenues from operations for the quarter ended December 31, 2009 was $1,014,052, a revenue increase of 93% from that reported in the third quarter of 2009.

Gross margin was 90% for the fourth quarter of 2009, compared to 63% for the third quarter of 2009.

The continuing operations loss in the quarter ended December 31, 2009 was reduced to a net loss of ($188,496) compared to a loss of ($794,172) for the quarter ended September 30, 2009.

Net income for the quarter ended December 31, 2009 was $4.4 million, including a $4.5 million gain from the sale of the Law Enforcement Division and income of $105,735 from discontinued operations.

Full Year 2009 Revenue and Income

Revenues from operations for the year ended December 31, 2009 was $2.4 million, a revenue decrease of 30% from the year ended December 31, 2008. The 2008 results reflected revenues from a large project for the FBI. Excluding that transaction, revenues grew year over year by 71%.

Gross margin was 79% for 2009, compared to 90% for 2008. Adjusting for the large project for the FBI, gross margin improved from approximately 76% in 2008.

The continuing operations loss in 2009 was ($2.5 million) compared to a loss of ($1.7 million) in 2008.

Net income for the full year ended December 31, 2009 was $4.7 million compared to net income of $0.1 million for 2008. The significant increase in year over year net income is attributable to the gain from the sale of the Law Enforcement Division.

2009 Balance Sheet

Profitable combined continuing and discontinued operations and the gain on the sale of the Law Enforcement Division provided the company with sufficient cash flow to retire $7.5 million of its outstanding preferred stock.

The company ended 2009 with substantial liquidity of approximately $800,000 in cash and about $850,000 in receivables. Further, the company’s remaining outstanding preferred stock is approximately $1 million less than the notes receivable owed to the company.

For the first time since the early years of the company’s inception, the company achieved a positive stockholders equity.

Management Discussion

Commenting on the fourth quarter and full year, Mike DePasquale, BIO-key CEO said, “We are thrilled that we were able to complete and profitably close the sale of our Law Enforcement business enabling us to dramatically improve and strengthen our Balance Sheet; and providing us with the resources to focus on our high-margin, high-growth leadership biometrics business.”

“I am particularly pleased with the strong revenue results of our fourth quarter biometrics business which nearly doubled in the fourth quarter from the preceding quarter. With 90% gross margins and continued cost discipline, we have calculated a break even profitability model of about $1 million dollars a quarter. This will give us the opportunity to grow profits as our revenue increases.“
