ROCHESTER, N.Y. – July 23, 2015 – Monro Muffler Brake, Inc. (Nasdaq: MNRO), a leading provider of automotive undercar repair and tire services, today announced financial results for its first quarter ended June 27, 2015.

First Quarter Results

Sales for the first quarter of fiscal 2016 increased 8.7% to $236.5 million as compared to $217.5 million for the first quarter of fiscal 2015. The total sales increase for the first quarter of $19.0 million was due to an increase in sales from new stores of $25.2 million, including sales from recently acquired stores of $23.1 million, partially offset by a comparable store sales decrease of .4%. Comparable store sales increased approximately 8% for alignments and were flat for tires and brakes. Comparable store sales decreased approximately 2% for maintenance services and exhaust and 3% for front end/shocks.

Gross margin increased to 42.2% in the first quarter from 41.4% in the prior year, largely due to the benefit of lower material costs as a percentage of sales and increased payroll efficiency. Total operating expenses were $66.1 million, or 28.0% of sales, as compared with $60.6 million, or 27.9% of sales, for the same period of the prior year. The increase in operating expenses as a percent of sales reflects costs associated with Monro’s fiscal 2015 and 2016 acquisitions, largely offset by focused cost control.

Operating income for the quarter increased 14.3% to $33.6 million from $29.4 million in the first quarter of fiscal 2015. Interest expense was $3.4 million as compared to $2.1 million in the first quarter of fiscal 2015.

Net income for the first quarter increased 11.0% to a record $18.8 million from $16.9 million in the prior year period. Diluted earnings per share for the quarter increased 9.6% to $.57, achieving the midpoint of the Company’s estimated range of $.55 to $.59. Earnings per share are net of approximately $.01 of due diligence costs related to completed and potential acquisitions. This compares to diluted earnings per share of $.52 in the first quarter of fiscal 2015. Net income for the first quarter of fiscal 2016 reflects an effective tax rate of 38.0% as compared with 38.1% for the prior year period.

The Company opened four locations and closed four locations during the first quarter, ending the quarter with 999 company operated stores and 145 franchised Car-X stores.

John Van Heel, President and Chief Executive Officer stated, “I am pleased to report that our continued focus on margin improvement and diligent cost control, combined with the outperformance of our recent acquisitions, allowed us to report an 11% increase in net income and 70 basis points of operating margin expansion. Our team’s strong execution and Monro’s ability to drive lower costs, coupled with the success of our recent acquisitions, further demonstrate that our business model is working. We were also encouraged to see that following a slow start to the first quarter, comparable store sales improved, turning slightly positive in May and June and increasing approximately 2% month-to-date in July on positive traffic trends. Overall, we remain confident in our business model and in our ability to increase our market share and deliver strong overall sales and earnings growth, in both strong and weak markets.”

Acquisitions Update

Monro Muffler Brake, Inc. announced today that it has signed definitive agreements to acquire 31 stores in New York, Pennsylvania, and Massachusetts. Twenty seven of these stores are located in central New York and Pennsylvania and will be rebranded as Mr. Tire stores, allowing the Company to fill in existing markets where it currently operates Monro Brake & Tire locations. This acquisition, which is expected to be completed in mid-August, significantly increases Monro’s market share in these markets, demonstrating the advantages of Monro’s two-brand strategy. The remaining four stores are located in

Massachusetts and will operate as Monro Brake & Tire locations. The Company completed the acquisition of these stores in July 2015. Combined, these 31 acquired stores are expected to add approximately $31 million in annualized sales, representing a sales mix of 60% service and 40% tires. These acquisitions are expected to be slightly dilutive to earnings per share in the second quarter, but breakeven in fiscal 2016, as cost synergies are expected to be realized more quickly due primarily to the Company’s ability to leverage existing distribution in these markets.

In April 2015, Monro Muffler Brake completed the previously announced acquisition of the Car-X brand, a chain of 146 franchised locations operating in ten states, three of which are new states for Monro. As previously announced, the Company expects Car-X to be slightly accretive to earnings per share in fiscal 2016.

Company Outlook

Based on current visibility, business and economic trends, and the recently completed and pending acquisitions, the Company now anticipates fiscal 2016 sales to be in the range of $950 to $970 million versus the previous guidance range of $935 to $955 million. The fiscal 2016 sales guidance reflects a comparable store sales increase of 1% to 3%. The Company continues to expect fiscal 2016 diluted earnings per share to be in the range of $2.00 to $2.20, as compared to $1.88 in fiscal 2015, representing earnings per share growth of 6% to 17% year-over-year on top of a 40% increase in the prior two years. Fiscal 2016 earnings per share guidance assumes $.12 to $.17 in contribution from recent acquisitions. This estimate is based on 33.1 million weighted diluted average shares outstanding.

For the second quarter of fiscal 2016, the Company anticipates sales to be in the range of $233 to $237 million and comparable store sales to increase 1% to 3%. The Company expects diluted earnings per share for the second quarter to be between $.54 and $.59, as compared to $.50 in the prior year period. The second quarter fiscal 2016 earnings per share guidance assumes slight dilution from higher due diligence costs related to potential transactions and includes $.02 of annual director stock option grants.

Mr. Van Heel concluded, “We are encouraged by our significant operating margin expansion, the successful integration of our recent acquisitions and the rebound in July’s comparable store sales. As we move forward, we will continue to actively manage our business through this choppy environment to drive strong bottom line results. We are also pleased by the acquisitions we’ve completed and announced already this year. Looking ahead, we remain very encouraged by the opportunities we see to complete additional accretive acquisitions in fiscal 2016. Overall, we are confident that our long-term strategic plan and the flexibility of our business model will continue to deliver increased market share and shareholder returns.”
