Exhibit 99.1

Actuate to Appeal Nasdaq Notice

    SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--June 3,
2003--Actuate Corporation (Nasdaq: ACTUE), the world leader in
scalable Business Intelligence Applications, today announced that
following the delayed filing of its Quarterly Report on Form 10-Q for
the first quarter of 2003, it received a Nasdaq Staff Determination on
May 27, 2003 indicating that Actuate has failed to comply with
Marketplace Rule 4310(c)(14) which requires the timely filing of
quarterly and annual reports with the Securities and Exchange
Commission and therefore is subject to delisting from the Nasdaq
National Market. Actuate has requested a hearing before a Nasdaq
Listings Qualification Panel to review the Staff Determination. During
the appeal process, Actuate's securities will continue to be listed on
the Nasdaq with the fifth character "E" appended, which temporarily
changes Actuate's trading symbol from ACTU to ACTUE.
    Actuate's Audit Committee and independent auditors are in the
process of completing an accounting review of selected sales
contracts. Actuate's management is working closely with the company's
independent auditors to expedite the filing of the company's 10-Q.
