   ANCHOR BANCORP WISCONSIN INC. ANNOUNCES FOURTH QUARTER AND FISCAL YEAR END
                                    EARNINGS

    MADISON, Wis., May 22 /PRNewswire-FirstCall/ -- Anchor BanCorp Wisconsin
Inc. (Nasdaq: ABCW) announced net income of $11.5 million for the quarter ended
March 31, 2006, and net income of $44.7 million for the twelve-month period
ended March 31, 2006. This compares to net income for the same quarter of the
previous fiscal year of $16.8 million and net income for the previous full
fiscal year of $48.3 million, which included a one-time gain of $5.4 million
after tax from the sale of part of our California real estate development
project during the fourth fiscal quarter of 2005.

    Diluted earnings per share were $.53 for the quarter ended March 31, 2006,
as compared to $.74 for the same quarter last year, which included a one-time
gain of .24 per share from the sale of part of our California real estate
development project. Diluted earnings per share were $2.03 for the twelve- month
period ended March 31, 2006, which compares to $2.10 for the same twelve-month
period last year.

    "Despite less favorable interest rate conditions for consumers than in the
past several years, we had strong asset growth of 5.5 percent and an overall
growth of 5.8% in loans, including a 22.3 percent growth in our mortgage-
related securities," said Douglas J. Timmerman, President. "We also experienced
a 5.8 percent growth in deposits for the fiscal year as consumers responded to
rising investment yields."

    "Our focus on managing margins while driving growth continues to pay off,"
added Timmerman. "Our interest rate spread increased from 3.19 percent to 3.23
percent for the quarter ended March 31, 2006, and from 3.16 percent to 3.25
percent for the twelve-month period ended March 31, 2006." Net interest margin
increased from 3.29 percent to 3.35 percent and from 3.27 percent to 3.36
percent for the same periods last year. An increase of 78 basis points for the
quarter ended March 31, 2006 and 64 basis points for the fiscal year in the
yield on earning assets contributed to the growth in net interest margin.

    During the quarter the board of directors approved a dividend of $.16 per
share payable to shareholders of record as of April 28, 2006. This represents an
18.5 percent increase from the same period in the prior fiscal year of $.135 per
share.
