“Safe Harbor” Statement

Except for the historical statements and discussions in this press release, the company’s statements above constitute forward-looking statements within the meaning of section 21E of the Securities Exchange Act of 1934. These forward-looking statements reflect Electro Rent’s management’s views and expectations at this time with respect to future events and financial performance, based on currently available information. Forward looking statements in this press release include statements regarding the completion of the sale transaction to Platinum Equity. When used, the words “anticipate”, “believe”, “expect” and “will” and other similar expressions identify forward-looking statements. Forward-looking statements are based on assumptions about future operations and market conditions, and are subject to certain risks and uncertainties. The company believes its assumptions are reasonable; nonetheless, it is likely that at least some of these assumptions will not come true. Accordingly, Electro Rent’s actual results will differ from the outcomes contained in any forward-looking statement, and those differences could be material. Factors that could cause or contribute to these differences include, among others, those risks and uncertainties discussed in the company’s periodic reports on Form 10-K and 10-Q and in its other filings with the Securities and Exchange Commission, including: general macroeconomic conditions may not improve or may deteriorate; U.S. federal government spending with respect to defense and other research and development activities may not increase or may decline; Electro Rent may not succeed in retaining its key sales or other personnel; competition may cause the company to lower prices and margins to effectively compete; and manufacturers of test and measurement equipment may not be willing to enter reseller arrangements with Electro Rent or those agreements may not succeed to the level anticipated. Should one or more of the risks discussed, or any other risks, materialize, or should one or more of our underlying assumptions prove incorrect, the company’s actual results may vary materially from those anticipated, estimated, expected or projected. In light of the risks and uncertainties, there can be no assurance that any forward-looking statement will in fact prove to be correct. You should not put undue reliance on these statements. Electro Rent undertakes no obligation to update or revise any forward-looking statements.
