                 HEI ANNOUNCES FIRST QUARTER FISCAL 2005 RESULTS

      -- Revenues grow 29% over first quarter of fiscal 2004

      -- Operations return to profitability

      -- Nasdaq continued listing requirements satisfied

    MINNEAPOLIS, Feb. 3 /PRNewswire-FirstCall/ -- HEI, Inc. (Nasdaq: HEIIE)
( http://www.heii.com ) today announced results for its first quarter of
fiscal 2005, which ended November 27, 2004.

    Net sales for the first quarter of fiscal 2005 were $14.1 million, a 29%
improvement over sales of $10.9 million reported in the first quarter of
fiscal 2004.  The Company reported net income of $415,000 or $0.05 per share
in the first quarter this year as compared to a loss of $1,253,000 or ($0.18)
per share last year.

    "We are extremely pleased to be able to report to our shareholders that
our efforts over the past two years are beginning to show positive results,"
said Mack Traynor, Chief Executive Officer and President.  "While I am very
happy with the growth in our sales levels, I am particularly pleased that the
changes in our manufacturing processes and procedures have enabled us to more
efficiently manufacture and ship more products in the quarter.  This has
resulted in a substantial improvement in our gross profit margins from 10% in
the first quarter last year to 21% in the first quarter this year.  As a
result, we are able to report an operating profit for the quarter."

    Traynor added, "We continue to work diligently to build on these positive
developments.  In addition to the operational improvements, we have taken a
number of actions over the past several months to strengthen our balance sheet
and financial position.  We ended the quarter with $300,000 of cash and
$2.7 million outstanding on our expanded credit facility.  As we previously
disclosed, in January our credit agreement was amended to increase our
borrowing capacity from $4.0 million to $5.0 million, subject to availability
based on accounts receivable."

    Traynor continued, "The Company will be filing its Form 10-Q for the
quarter ended November 27, 2004 later today.  We are currently awaiting the
decision from our January 20, 2005 hearing before a Nasdaq Listing
Qualifications Panel, and we believe that the filing of the Form 10-Q will
demonstrate our compliance with all requirements for continued listing on The
Nasdaq National Market."  The Company plans to make a further announcement
upon receipt of the Panel's decision, which will include the expected date for
removal of the "E" from the Company's trading symbol.

    "The results we achieved in the first quarter represent only one step in
our long-term plan for the continued growth and profitability of HEI.  I want
to thank all of our employees for all their hard work over the past two years
to get us to this point.  I also want to thank our customers, vendors and
shareholders for their continued support," concluded Mr. Traynor.

    The Company will hold a conference call to discuss the Company's operating
results and business strategies on Thursday, February 3, 2005 at 4:00 p.m.
Eastern Time (3:00 p.m. Central Time).  This call is being web-cast and can be
accessed via the HEI web site at http://www.heii.com .  The call will be
recorded and be available after the call at this same location on the web
