Exhibit 99.1

ACTUANT PROVIDES QUARTERLY IMPACT OF NEW STOCK OPTION

ACCOUNTING RULE; ANNOUNCES INVESTOR CONFERENCE AND

FILING OF SHELF REGISTRATION STATEMENT

MILWAUKEE, WI, July 15, 2005 — Actuant Corporation (NYSE: ATU) provided today the quarterly impact of the adoption of the provisions of Financial Accounting Standards Board Statement No. 123R, “Accounting for Stock Based Compensation.” The Company had previously announced its intention to adopt the new accounting standard in the fourth quarter of fiscal 2005 using the modified retrospective method. Under this adoption method, the first three quarters of fiscal 2005 will be restated in future filings to reflect expense for stock based compensation as required under the new rule. The total estimated impact of the new accounting rule for the twelve months ended August 31, 2005 is a $2.7 million non-cash reduction to net income or a $0.09 per share reduction in diluted earnings per share (“EPS”). The quarterly impact of the adoption of this new accounting rule on previously reported results is reflected on the schedules attached to this press release.

In an unrelated matter, the Company announced that it has filed a universal shelf registration statement on Form S-3 with the Securities and Exchange Commission. Once declared effective by the Securities and Exchange Commission, the shelf registration statement will permit Actuant to sell, in one or more offerings, common stock, preferred stock, debt securities, stock purchase contracts and units, depositary shares and warrants, or any combination of the foregoing in an aggregate amount of up to $900 million. Robert C. Arzbaecher, President and CEO of Actuant commented, “While we have no immediate plans to draw funding from the new shelf registration, its existence allows us additional flexibility to pursue our growth initiatives. Any new funding under the registration statement will require the prior approval of our Board of Directors.”

The Company also announced that it will be hosting an investor conference at The Waldorf=Astoria^® hotel in New York City on the afternoon of August 4, 2005. For more information on the conference, or to make a reservation, please contact Ann Ertl at (414) 247-5241 or ann.ertl@actuant.com.
