SEMCO ENERGY, INC.
DIRECT STOCK PURCHASE
AND
DIVIDEND REINVESTMENT PLAN
SUPPLEMENT TO
PROSPECTUS DATED DECEMBER 22, 1999
SEMCO Energy, Inc. is changing its Direct Stock Purchase and Dividend
Reinvestment Plan ("DRIP") to provide for weekly purchases of common stock.
Currently, Norwest Bank uses Participants' optional cash payments to purchase
stock only once a month. Starting June 5, 2000, Norwest will make stock
purchases weekly. Therefore, Participants' cash payments will be invested
approximately four times a month, on the first business day of each week or as
soon thereafter as feasible.
This change does not affect the reinvestment of cash dividends.
This change also does not affect the method of determining the price paid
for stock. As before, if Norwest Bank purchases common stock on the open market
or in private transactions, the price paid by Participants will be the average
price paid by Norwest. If Norwest purchases common stock directly from SEMCO,
the price paid by Participants will be the average of the closing prices on the
New York Stock Exchange on the three trading days preceding the purchase.
This change will make it easier for Norwest Bank to purchase shares of
SEMCO's common stock and cause Participant cash payments to be invested more
frequently. A cash payment will be refunded if a request is received by Norwest
at least one full business day prior to the first business day of the week in
which the cash payment would have been invested.
Investment statements will be mailed weekly.
The most recent DRIP Prospectus is dated December 22, 1999. Please keep
this letter with that DRIP Prospectus for future reference.
If you have any concerns with this change, you may contact Norwest Bank at
1-877-536-3549 or 1-651-450-4064 between 7:00 a.m. and 7:00 p.m. Central Time.
