ROCHESTER, N.Y. – May 22, 2014 – Monro Muffler Brake, Inc. (NASDAQ: MNRO), a leading provider of automotive undercar repair and tire services, today announced financial results for its fourth quarter and fiscal year ended March 29, 2014.

Fourth Quarter Results

Sales for the fourth quarter of fiscal 2014 increased 3.7% to a record of $203.2 million as compared to $195.9 million for the fourth quarter of fiscal 2013. The sales increase for the fourth quarter was due primarily to an increase in sales from newly acquired stores, offset by a comparable store sales decrease of 1.3%. Comparable store sales were relatively flat for the maintenance and exhaust categories, and decreased approximately 2% for tires, brakes and alignments, and 3% for front end/shocks.

Gross margin improved 190 basis points to 37.9% in the fourth quarter from 36.0% in the prior year due to reduced material costs and payroll control. Total operating expenses were $55.6 million, or 27.4% of sales, as compared with $55.1 million, or 28.1% of sales, for the same period of the prior year. The decrease in operating expenses as a percent of sales is due to leverage from higher overall sales and focused cost control, partially offset by higher utilities due to the more severe winter weather.

Operating income for the quarter increased 38.4% to $21.4 million from $15.5 million in the fourth quarter of fiscal 2013. Interest expense was $2.4 million as compared to $3.1 million in the fourth quarter of fiscal 2013.

Net income for the fourth quarter increased 46.5% to a record $11.9 million from $8.1 million in the prior year period. Diluted earnings per share for the quarter increased 44.0% to $.36, and exceeded the Company’s estimated range of $.32 to $.35. This compares to diluted earnings per share of $.25 in the fourth quarter of fiscal 2013. Net income for the fourth quarter reflects an effective tax rate of 37.6% as compared with 34.8% for the prior year period.

The Company opened four and closed two locations during the fourth quarter, ending the quarter with 953 stores.

Fiscal Year Results

Net sales for fiscal 2014 increased 13.6% to $831.4 million from $732.0 million for fiscal 2013. The total sales increase for the fiscal year of $99.4 million was due to an increase in sales from recently acquired stores, partially offset by a .5% decrease in comparable store sales.

Gross margin improved 50 basis points to 38.5% for fiscal 2014 as compared to 38.0% in the prior year due to reduced product costs, payroll control, and leverage of distribution and occupancy costs, which more than offset a sales mix shift to the lower margin tire category, related primarily to recently acquired stores.

Total operating expenses were $224.6 million, or 27.0% of sales, for fiscal 2014, as compared with $204.4 million, or 27.9% of sales, for the prior fiscal year. The year-over-year decrease in operating expenses, as a percentage of sales, of 90 basis points, is due to leverage from higher overall sales and focused cost control. Operating income for the year increased 29.4% to $95.3 million from $73.7 million in fiscal 2013. Interest expense was $9.5 million in fiscal 2014 as compared to $7.2 million in fiscal 2013.

Net income for fiscal 2014 increased 27.9% to $54.5 million, or $1.67 per diluted share. This compares to net income of $42.6 million, or $1.32 per diluted share, for fiscal 2013.

John Van Heel, President and Chief Executive Officer stated, “We are very pleased with our team’s ability to deliver earnings results ahead of expectations for the fourth quarter due to 1% higher comparable store tire units, improved margins, our ongoing focus on cost control and continued outperformance of our recent acquisitions. While we were hopeful that consumer spending would have been stronger, we were encouraged that we ended fiscal 2014 with positive traffic driven by an increase of 1% in comparable store oil change and tire units for the year, demonstrating that customers are continuing to service their vehicles at our stores. At the same time, we experienced some weather-related disruption to our business in the fourth quarter, while throughout the fiscal year, we saw customers continue to delay purchases and trade down from higher cost tires and automotive maintenance and repair purchases. Notably, customer acceptance of our expanded tire offerings, and our execution on our recent acquisitions, were better than planned and drove our significant increase in operating margin for the quarter and the year. Overall, we ended fiscal 2014 strongly positioned to continue leveraging our flexible business model and pursuing our disciplined acquisition strategy. We remain confident in our ability to further increase our market share and deliver strong sales and earnings growth in both strong and weak environments.”

Cash Dividend Increased 18%

The Company also today announced that its Board of Directors has approved a $.02 increase in the Company’s cash dividend for the first quarter of fiscal year 2015 to $.13, which translates to an annual rate of $.52 per share and represents an increase of $.08 per share or 18% from the dividends paid in fiscal 2014. The cash dividend is payable quarterly to shareholders of record on the Company’s outstanding shares of common stock including the shares of common stock to which the holders of the Company’s Class C Convertible Preferred Stock are entitled. The dividend of $.13 per share for the first quarter of fiscal 2015 will be payable on June 12, 2014 to shareholders of record as of June 2, 2014.

Acquisitions Update

Monro Muffler Brake also announced today that it has signed definitive agreements to acquire 21 stores that are expected to generate approximately $16 million in annualized sales. The acquisition of these stores allows the Company to extend its geographic footprint into Michigan, a new state for the Company, with 19 stores which will operate under the Monro Brake & Tire brand. The remaining acquired stores fill in an existing market. These acquisitions are expected to add approximately 2% annualized sales growth on top of the Company’s over 30% acquisition sales growth achieved in the 11 deals closed in fiscal 2013 and 2014. The transactions are expected to close this quarter.

Company Outlook

Based on current visibility, business and economic trends, and the acquisitions we expect to complete in our first quarter, the Company anticipates fiscal 2015 sales to be between $875 and $905 million. Comparable store sales in fiscal 2015, which now include the acquisitions made in fiscal 2013, are anticipated to increase in the range of 1% to 4%. Fiscal 2015 diluted earnings per share are expected to be in the range of $1.95 to $2.15, an increase of 17% to 29% as compared to $1.67 diluted earnings per share in fiscal 2014. The estimate is based on 32.8 million weighted average shares outstanding.

For the first quarter of fiscal 2015, the Company anticipates comparable store sales to increase in the range of 2% to 3%. The Company expects diluted earnings per share for the first quarter to be between $.52 and $.55, with the fiscal 2015 acquisitions slightly dilutive, as compared to $.42 for the first quarter of fiscal 2014. First quarter comparable store sales to date are up 2%, on top of a 3% increase for the same period in the first quarter of fiscal 2014, due to positive oil change and tire units and strength in our service business.

Mr. Van Heel concluded, “Our long-term outlook for the industry and company remains positive. We are pleased that severe winter weather experienced across our markets and our strong customer relationships are driving increased traffic and required repairs early this fiscal year. We continue to actively manage our business in this environment, where we see the consumer continue to trade down and allocate spending to essential needs. We are also pleased that our expanded tire assortment continues to provide value to consumers and, at the same time, drives increased profitability in our business. Our acquisitions continue to outperform and we expect the transactions we have completed in the past two fiscal years to be significantly accretive to earnings. We look forward to the contributions from the acquisition of the 21 stores we announced today. In addition, we remain very encouraged by the opportunities we see to complete further acquisitions in the near future and expect this year to be strong for acquisition growth. Finally, the increase in our cash dividend announced today, which is the ninth increase in the last nine years, reflects the Board’s continued confidence in Monro’s long-term strategic plan and commitment to increasing shareholder returns.”
