                   HEI PROVIDES BUSINESS AND FINANCIAL UPDATE

MINNEAPOLIS,  April  19, 2001 -- HEI, Inc. (Nasdaq: HEII, www.heii.com) a leader
in  the  design and manufacture of microelectronics for the hearing, medical and
communications  markets, today provided a financial update and status of actions
taken  to  address  current  business  and  economic  issues.

Due  to  the continued general economic downturn, and specifically a slowdown in
the  hearing,  RFID/Access,  and  electronic contract manufacturing markets, HEI
expects  revenue  for its fiscal third quarter to be down 5% to 10% sequentially
from  fiscal  second quarter, but 5% above third quarter a year ago. The Company
expects  a third quarter net loss of approximately 11 cents per share, including
expenses  associated  with  the  phase out of the Mexico manufacturing facility.
This facility will be completely phased out in the third quarter with profitable
programs  in  strategic  markets  being transferred to other HEI locations.  The
Company is taking this action to focus its resources as it expands its broadband
and  hearing  businesses.  For  the four quarters ended March 3, 2001, HEI would
have earned 45 cents per share if the losses associated with the Mexico facility
were  excluded, compared to a reported net income of 3 cents per share including
the  losses  associated  with  the  Mexico  facility.

The  Company  believes  that the hearing and medical markets will improve in the
fourth  quarter  of 2001.  This combined with HEI's expansion into the broadband
market  will  result  in  fourth  quarter  revenue  growth compared to the third
quarter  of  this  fiscal  year and the fourth quarter of last fiscal year.  HEI
expects  fourth quarter net income in the single digit earnings per share range,
as  well  as  significant  revenue  growth  and  improved  earnings  in  FY2002.
