A Message from HEI to our Shareholders and the Community:
LET'S SET THE RECORD STRAIGHT
For the past several months, the shareholders of Minnesota-based HEI have been
subjected to an unfortunate and extremely expensive struggle for control of HEI
and its assets. Everything from HEI's performance and prospects to the
integrity of the Board and management has come under public attack in a series
of misleading ads and public statements by the opposition. Over the same
period, our employees, customers, suppliers, friends, community leaders, and
shareholders have endured this mischaracterization and asked why we haven't
responded in the media. The answer is commitment and responsibility.
We have a duty to focus on growing our business and providing return for our
shareholders. We continue to do so; however, we have a responsibility to set
the record straight. The charts below show HEI's achievements, its solid
financial base and its excellent prospects for the future.
