ROCHESTER, N.Y. — January 28, 2010 — Monro Muffler Brake, Inc. (Nasdaq: MNRO), a leading provider of automotive undercar repair and tire services, today announced record financial results for its fiscal 2010 third quarter ended December 26, 2009.

Third Quarter Results

Sales for the third quarter of fiscal 2010 increased 28.7% to a record $152.7 million compared to $118.7 million for the third quarter of fiscal 2009. Sales were driven largely by strong in-store sales execution across all categories and increased store traffic. Comparable store sales increased 7.2%, on top of a 5.9% comparable store sales increase in the third quarter of the prior year, and in-line with the Company’s previously estimated range of 6% to 8%. By category, comparable store sales increased approximately 13% for alignments, 11% for shocks, 10% for tires, 8% for exhaust, 6% for brakes, and 3% for maintenance services.

The total sales for the quarter included an increase in sales from new stores of $28.8 million. The 26 Autotire stores acquired in June 2009 contributed $8.6 million of the increase, and the 45 Midwest Tire and Tire Warehouse stores acquired in September and October 2009, respectively, contributed $18.7 million of the increase.

Gross margin was 38.3% in the third quarter compared to 38.1% in the prior year quarter and reflects previously implemented price increases, improved labor productivity and leveraging of fixed occupancy costs included in cost of sales. These factors were offset by a continued sales mix shift toward lower margin tire sales mostly driven by the addition of the 71 recently acquired tire stores.

Total operating expenses were $44.3 million, or 29.0% of sales, compared with $35.3 million, or 29.7% of sales, for the same period of the prior year and reflect leveraging of the cost structure on increased sales. Operating income for the quarter increased 43.7% to $14.3 million from $9.9 million in the third quarter of fiscal year 2009. Interest expense was $1.0 million, down from $1.5 million in the prior year’s third quarter.

Net income for the third quarter increased 41.8% to a record $7.9 million compared to $5.6 million for the prior year period. Diluted earnings per share for the quarter increased 35.7% to $.38, above the Company’s previously estimated range of $.32 to $.35, and compared to diluted earnings per share of $.28 in the third quarter of fiscal 2009. Net income for the third quarter reflects an effective tax rate of 40.7% compared with 34.2% for the prior year period. Pre-tax income for the third quarter increased to a record $13.3 million, a 57.1% increase over the prior year period.

The Company added 42 locations through acquisitions and closed one location during the quarter, ending the third quarter of fiscal 2010 with 780 stores.

First Nine Month Results

For the nine-month period, net sales increased 16.3% to a record $417.4 million from $359.0 million in the same period of the prior year. Net income for the first nine months of fiscal 2010 increased 29.8% to a record $27.3 million, or $1.33 per diluted share, compared with $21.0 million, or $1.05 per diluted share in the comparable period of fiscal 2009.

Robert G. Gross, Chairman and Chief Executive Officer stated, “We are very pleased that the momentum we built over the last two years has continued into the second half of fiscal 2010. Our strong results for the third quarter demonstrate that we continue to gain market share and capitalize on favorable macro economic factors, most importantly, continued weak new vehicle sales and dealer closings. Additionally, we are very encouraged by our recent opportunistic, value-added acquisitions, all of which have been accretive to earnings from the start. During the quarter, we continued to focus on our store

execution and to invest in advertising and employee training. These initiatives, coupled with our strong reputation as a trusted service provider, have us on track for our ninth straight year of same store sales increases, with an increase of approximately 7% for the third quarter and year-to-date.”

Company Outlook

Based on year-to-date performance and current business and economic trends, the Company anticipates fourth quarter comparable store sales growth to be in the range of 5% to 7% and diluted earnings per share to be in the range of $.20 to $.23, compared to $.15 for the fourth quarter of fiscal 2009.

For fiscal 2010, the Company continues to expect comparable store sales growth of 6% to 7%. The Company now expects total fiscal 2010 sales in the range of $555 million to $561 million compared to $476 million last year. The Company raised its estimated range for fiscal 2010 diluted earnings per share to $1.53 to $1.56 from its previously estimated range of $1.44 to $1.48, and $1.20 last year. The estimate is based on 20.6 million weighted average shares outstanding.

Mr. Gross concluded, “We have continued to execute well against our business strategy and remain optimistic as we head into the fourth quarter. Our January comparable store sales increased approximately 9%, on top of a very strong 14.6% last January. We are extremely pleased with the performance of our recent acquisitions, which also provide us with an opportunity to convert 53 service stores in New England to our Black Gold format over the next three months. Additionally, we would hope to close acquisition deals by the end of this quarter that would add approximately $20 million in annual sales. As we look to the fourth quarter, we continue to view the current trends in our industry, our business and acquisition opportunities favorably, and are excited about what fiscal year 2011 will bring.”
