TOLLGRADE REPORTS SECOND QUARTER 2010 RESULTS

TOP LINE GROWTH AND A RETURN TO PROFITABILITY

PITTSBURGH, PA August 3, 2010 — Tollgrade Communications, Inc. (NASDAQ: TLGD), a leading supplier of network service assurance test products and solutions, today reported revenue of $11.5 million and net income of $1.2 million or $0.10 per share for the second quarter ended June 30, 2010. Revenue and net income increased by approximately $0.9 million and $2.7 million compared to the second quarter of 2009 representing increases of 8% and 181%, respectively. The results for the second quarter of 2010 also include the effects of net severance charges of approximately $0.6 million which were primarily associated with the departure of the Company’s former chief executive officer.

“We took action to realign our business beginning in the fourth quarter of 2009 and accelerated our efforts to significantly reduce operating costs during the first quarter of 2010. Our reduced operating cost structure had a major impact on our ability to report a profit during the second quarter of 2010, and we believe these actions have positioned the Company to sustain profitability in the future and to be more competitive in the marketplace, helping us to drive top line growth. Our primary focus continues to be on our installed customer base and securing revenue from existing and new customer projects as well as long term maintenance agreements. We are committed to delivering the highest levels of service to our customers and we are confident that our reduced operating cost structure has not affected our ability to continue to deliver the level of service our customers have come to expect,” said Edward Kennedy, President and Chief Executive Officer.

Mr. Kennedy added, “We have recently finalized a nine month maintenance contract extension with a major European service provider and are in the process of finalizing a new multi-year maintenance contract with another major European provider. Currently, we have multiple customer trials underway that we believe will create revenue opportunities in the second half of 2010 and in 2011. Our workforce is energized and committed to achieving our goals and driving shareholder value.”

As of June 30, 2010, our cash and short-term investments position was $64.1 million compared to $66.0 million at December 31, 2009. The decrease of $1.9 million primarily reflects cash used for severance payments as well as the timing of accounts receivable collections. As of the end of July, our cash and short-term investment position was approximately $66.6 million.

Third Quarter 2010 Outlook

“We expect revenue to be in the range of $11 million to $13 million for the third quarter of 2010. We believe our collective revenue opportunities and our reduced cost structure will position the Company to sustain profitability and provide greater returns to our shareholders,” said Mr. Kennedy.
