Mirenco Improves Financial Performance

RADCLIFFE, Iowa--Feb. 2, 20058, 2005--Mirenco, Inc., (OTCBB:MREO) reports a loss of 9 cents per share for the fiscal year ending December 31, 2004 compared to a loss of 12 cents for the fiscal year ending December 31, 2003. The fourth quarter of 2004 resulted in a loss of 1 cent per share versus 3 cents for the same period the previous year. These results are subject to the completion of the audit being conducted by Mirenco's auditors; Stark, Winter, Schenkein & Co., LLP.

"The narrowing of the loss is significant because it demonstrates that through our plan of redirecting costs to our marketing efforts; which is now generating a sales stream and reducing research, development and administrative costs, we are moving closer to breakeven and profitability," says Rich Musal, Mirenco's Chief Operating Officer and Chief Financial Officer. "We have increased our sales commitments for 2005 significantly since the fourth quarter of last year and by controlling our costs and continually increasing sales through the acceptance of our products, we will quickly close the distance to profitability."

"We had to prove the capability of our products to our customers in the underground mining and truck fleet markets. We have turned the corner in doing so as demonstrated by attracting new clients including; Wells Blue Bunny, Holiday Express and Abbott Labs. This makes our products much more attractive to distributors and national accounts. We have begun the evaluation stages with customers in both the distributor and national account categories recently and are seeking more opportunities at these levels," Musal stated.
