HEI, INC. ANNOUNCES THIRD QUARTER FISCAL YEAR 2002 RESULTS

REPORTS THIRD QUARTER PROFIT

MINNEAPOLIS, June 20, 2002 — HEI, Inc. (Nasdaq: HEII, www.heii.com) today announced financial results for its third quarter ended June 1, 2002. Net sales for the third quarter were $8,500,000 as compared to $10,331,000 for the third quarter of the previous year, and up 9% from second quarter net sales of $7,795,000. Net income for the third quarter was $115,000, or 2 cents per share fully diluted, compared to a net loss of $652,000, or 13 cents per share fully diluted for the same period a year ago, and a net loss of $310,000 or 5 cents per share fully diluted for second quarter.

“In the third quarter HEI returned to profitability earning 2 cents per share, which is consistent with our previous guidance. We had a higher value mix of products, improved yields, and strong expense controls as shown by overhead and operating expense reductions,” said Don Reynolds, President and Chief Operating Officer of HEI, Inc. “Third quarter gross margins increased to 25% as compared to 16% for the third quarter of the previous year, and 20% for the second quarter of this year,” added Mr. Reynolds.

“Based on bookings early in the quarter, it looks as though fourth quarter sales may be down slightly from the third quarter and similar to the fourth quarter of the previous year. We continue to see new program wins in the medical and hearing markets, and anticipate sales growth in these markets as we move into fiscal year 2003,” said Anthony Fant, Chairman and Chief Executive Officer of HEI, Inc. “Our new products and the proprietary technology we’ve invested in over the past year continue to gain acceptance in the broadband fiber-optic and wireless communications markets. We are confident that HEI is positioned to deliver products to the leaders in these industries as growth in the telecommunications markets return. Our goal is to remain profitable as we continue to bring new products to each of our focus markets,” Mr. Fant added.
