HYTEK REPORTS THIRD QUARTER RESULTS

Carson City, NV – November 10, 2003 – Hytek Microsystems, Inc. (OTC Bulletin Board: HTEK) announced today unaudited results for the three and nine month periods ended September 27, 2003.

The Company incurred a net loss of $182,887, or ($0.06) per share, for the three months ended September 27, 2003, as compared to a net loss of $377,684, or ($0.12) per share, for the same period last year. Net revenues were $2.5 million for the third quarter of 2003, compared to prior year third quarter net revenues of $2.7 million.

For the first nine months of fiscal 2003, the Company had a net loss of $389,428, or ($0.12) per share, as compared to a net loss of $59,427, or ($0.02) per share, for the first nine months of fiscal 2002. Net revenues for the nine-month period in 2003 were $7.6 million, a 19% decrease from net revenues of $9.4 million for the same period in 2002.

At September 27, 2003, current backlog was approximately $5.7 million as compared to $6.5 million at June 28, 2003.

Although Hytek incurred a net loss of $182,887 for the third quarter of 2003, on a 6% decrease in revenues during that quarter, operating results were improved over the comparable period last year.

“We are continuing our internal efforts to improve operational efficiencies, add management expertise, attract new customers and expand business opportunities with existing customers,” stated John Cole, Hytek’s chief executive officer. “These are ongoing programs that generate results as changes are implemented over time. Consequently, we do not expect to see significant improvements in operating results this fiscal year.”

Founded in 1974, Hytek, headquartered in Carson City, Nevada, specializes in custom microelectronic packaging solutions for use in oil exploration, military applications, satellite systems, industrial electronics, opto-electronics and other OEM applications.
