SERVIDYNE ANNOUNCES RESTATEMENT OF FINANCIAL RESULTS

Revising the timing of a previously recorded increase in the valuation allowance of deferred
state income tax assets; the change will reduce the Company’s year-to-date net loss from
continuing operations by $643,000, or 28%, and have no impact on the Company’s most
recent balance sheet or prior or future period cash flows.

ATLANTA — April 27, 2011 — SERVIDYNE, INC. (Nasdaq: SERV), an energy efficiency and demand response company, today reported that the Company will restate its financial results to revise the timing of a previously recorded increase in the valuation allowance on deferred state income tax assets. The financial statements covered by the restatement are included in the Company’s Form 10-K for the year ended April 30, 2010, and the Quarterly Reports on Form 10-Q for the periods ended July 31, 2010, October 31, 2010, and January 31, 2011. The expected impact will be to reduce the net loss from continuing operations for the first nine months of the current fiscal year by $643,000, and to increase the total combined net loss from continuing operations in the prior two fiscal years by the same amount. The Company plans to file the restated financial statements as promptly as practicable.

The restatement is necessitated by the Company’s determination that the valuation allowance on state deferred tax assets that was fully recorded in the fiscal third quarter ended January 31, 2011, should have been recorded beginning as of the fiscal year ended April 30, 2009, and adjusted in each subsequent fiscal period. The correction of the financial statements will have no impact on the Company’s previously reported balance sheet for the most recent quarter ended January 31, 2011, but will reduce the amount of deferred tax assets on the balance sheet for the fiscal years ended April 30, 2009, and April 30, 2010, and the fiscal quarters ended July 31, 2010, and October 31, 2010, by varying amounts.

“The accounting treatment for deferred income tax assets is complex and requires a great deal of judgment,” noted Alan R. Abrams, Chairman of the Board and Chief Executive Officer. “While it is unfortunate to have to amend our previously announced financial results, I believe that we are following a sound and conservative interpretation of the relevant standards.

“It is important to note that this correction simply involves moving a substantial majority of the non-cash income tax valuation allowance that we originally fully expensed last quarter into earlier fiscal periods, which will have no impact on our previously reported pre-tax results and no impact on our prior or future period cash flows.”

Additional information regarding the restatement will be included in a Form 8-K being filed today by the Company with the U.S. Securities and Exchange Commission.
