ROCHESTER, N.Y. – October 23, 2014 – Monro Muffler Brake, Inc. (Nasdaq: MNRO), a leading provider of automotive undercar repair and tire services, today announced financial results for its second quarter ended September 27, 2014.

Second Quarter Results

Sales for the second quarter of fiscal 2015 increased 7.8% to a record $221.3 million as compared to $205.3 million for the second quarter of fiscal 2014. The total sales increase for the second quarter of $16 million was due to an increase in sales from new stores of $18.9 million, including sales from recently acquired stores of $16.5 million, offset by a comparable store sales decrease of 2%. Comparable store sales increased approximately 5% for alignments and 4% for brakes, while comparable store sales were flat for front end/shocks and decreased approximately 2% for maintenance services, 4% for tires, and 6% for exhaust.

Gross margin increased to 40.4% in the second quarter from 39.8% in the prior year, largely due to the benefit of lower material costs, partially offset by higher distribution and occupancy costs. Total operating expenses were $60.5 million, or 27.4% of sales, as compared with $57.8 million, or 28.2% of sales, for the same period of the prior year. The decrease in operating expenses as a percentage of sales reflects leverage on higher sales and the Company’s diligent cost control in the face of a difficult sales environment.

Operating income for the quarter increased 21% to $28.9 million from $23.9 million in the second quarter of fiscal 2014. Interest expense was $2.8 million as compared to $2.0 million in the second quarter of fiscal 2014.

Net income for the second quarter increased 19.6% to a record $16.3 million from $13.6 million in the prior year period. Diluted earnings per share for the quarter increased 19.0% to $.50, within the Company’s estimated range of $.50 to $.52. This compares to diluted earnings per share of $.42 in the second quarter of fiscal 2014. Net income for the second quarter reflects an effective tax rate of 38.1%, in line with the prior year period.

The Company added 42 locations during the quarter, including 35 acquired stores and seven greenfield locations, while closing five stores, ending the quarter with 1,003 stores.

John Van Heel, President and Chief Executive Officer stated, “We were able to expand operating margin by 140 basis points and increase net income by 20% as a result of significant contributions from our recent acquisitions, higher gross margins, and disciplined cost control. Despite a difficult macro-economic environment, consumers continued to turn to Monro as a trusted service provider to perform basic maintenance on their vehicles, as demonstrated by increases in key service categories this quarter, including brakes and alignments, which continued the positive trend we saw in the first quarter. For the first half of fiscal 2015, while overall traffic was up approximately 1% and comparable tire units were flat, comparable tire sales decreased 4% as consumers remained cautious and continued to trade down on higher ticket purchases. Looking forward, we expect this choppy market to continue in the short term, but remain focused on driving top-line growth and leverage through acquisitions while aggressively managing costs in order to continue to deliver strong earnings growth.”

Acquisitions Update

Monro Muffler Brake also announced today the acquisition of nine stores in the Atlanta, Georgia area, a new state for Monro, further filling in the Company’s geographic footprint in key markets. This acquisition was completed in fiscal October 2014. Additionally, in August 2014, the Company completed the previously announced acquisition of 35 The Tire Choice locations in Florida, located in major west coast and east coast Florida markets. These acquisitions provide a solid foundation for continued store

growth in these large markets. On a combined basis, the Company’s acquisitions completed to date in fiscal 2015 add 63 locations, with total annualized sales of approximately $75 million, representing approximately 9% annualized sales growth with an approximate sales mix of 60% service and 40% tires.

Company Outlook

The Company’s guidance is based on current visibility, business and economic trends, and the recently completed acquisitions. The Company now anticipates fiscal 2015 comparable store sales to be approximately flat versus the prior range of an increase of 1% to 3%. As a result primarily of the weaker sales guidance, the Company is also revising its estimated fiscal 2015 diluted earnings per share to be in the range of $1.85 to $1.95, versus its prior range of $1.95 to $2.08. This compares to diluted earnings per share of $1.67 in fiscal 2014. Compared to fiscal 2014, the revised guidance range represents an earnings per share increase of 11% to 17%, respectively, at the low and high end of the range. The estimate is based on 32.8 million weighted diluted average shares outstanding. The Company now expects its total sales for the year to be in the range of $900 to $910 million.

For the third quarter of fiscal 2015, the Company anticipates comparable store sales to be in the range of a decrease of 2% to flat versus the prior year. The Company expects diluted earnings per share for the third quarter to be between $.47 and $.52, as compared to $.47 for the third quarter of fiscal 2014, which represented a 34% increase over the third quarter of fiscal 2013. Last year’s third quarter diluted earnings per share included a benefit of $.03 resulting from favorable lease purchase accounting and tax adjustments. The Company’s guidance for the third quarter reflects current month-to-date comparable store sales trends, incremental warehousing and logistics costs related to the increase in the Company’s tire inventory in advance of potential tariffs on imported tires, and slight dilution from acquisitions completed in fiscal 2015.

Mr. Van Heel continued, “Trends to date in the third quarter have remained challenging, with month-to-date comparable store sales down approximately 1.5%. While we are cautious in our outlook regarding near term sales trends, we believe that there is potential for upside in our comparable store sales trends in the second half of the fiscal year as more consumers look to address their tire and service needs following last year’s harsh winter and an extended deferral cycle. Additionally, as a result of recent pricing increases, we anticipate that the price and mix impact on tire sales, which has pressured overall comparable store sales by approximately 1.5% in the first half of the fiscal year, will turn positive in the fourth quarter.”

Mr. Van Heel concluded, “Our long-term view of the industry and our business remains positive. We continue to leverage our competitive advantages, including our strong balance sheet and low borrowing costs, to accelerate acquisitions in light of the difficult operating environment, lock in lower product costs by purchasing ahead of a potential tariff on imported tires and leverage our scale to negotiate favorable pricing with our vendors. Our full year expectations of double-digit earnings growth and operating margin improvement of 100 to 150 basis points (excluding current year acquisitions), based on flat comparable store sales, reflects the benefits of our recent actions and flexibility of our unique business model. We remain confident in our ability to drive strong earnings growth and deliver shareholder value in all types of economic and operating environments.”
