ROCHESTER, N.Y. – July 20, 2017 – Monro Muffler Brake, Inc. (Nasdaq: MNRO), a leading provider of automotive undercar repair and tire services, today provided financial results for its first quarter ended June 24, 2017.

First Quarter Results

Sales for the first quarter of fiscal 2018 increased 18.4% to $278.5 million, as compared to $235.3 million for the first quarter of fiscal 2017. The total sales increase for the first quarter of $43.2 million was due to sales from new stores of $41.5 million, including sales from recent acquisitions of $34.8 million and a comparable store sales increase of 1.4%, as compared to a decrease of 6.9% in the prior year period. Comparable store sales increased approximately 6% for brakes, 3% for front end/shocks, were flat for tires and maintenance services and decreased approximately 2% for alignments.

Gross margin decreased 120 basis points to 40.5% in the first quarter from 41.7% in the prior year period, primarily due to the impact of sales mix from recent acquisitions. On a comparable store basis, gross margin increased approximately 110 basis points largely due to the benefit of lower material costs as a percentage of sales. Total operating expenses increased by $12.4 million to $79.1 million, or 28.4% of sales, and remained flat as a percentage of sales compared to the same period last year.

The year-over-year dollar increase represents expenses from 55 net new stores and fees related to the management transition. On a comparable store basis, excluding management transition costs, total operating expenses increased approximately $2.9 million, primarily due to increases in performance-based store manager compensation and advertising expense.

Operating income was $33.7 million, or 12.1% of sales, or 12.4% excluding management transition costs, as compared to $31.3 million, or 13.3% of sales in the prior year period. Interest expense was $5.7 million as compared to $4.5 million for the first quarter of fiscal 2017.

Net income for the first quarter of fiscal 2018 was $17.6 million, as compared to $16.8 million in the same period of the prior year. Diluted earnings per share for the quarter were $.53, or $.55 when adjusting for $.02 per share in management transition costs, achieving the higher end of the Company’s guidance range of $.52 to $.56. This compares to diluted earnings per share of $.50 in the first quarter of fiscal 2017 and represents a 10% increase in earnings per share year-over-year. Net income for the first quarter of fiscal 2018 reflects an effective tax rate of 37.2%, as compared to 37.9% in the prior year period.

During the first quarter of fiscal 2018, the Company opened seven and closed six Company-operated locations, ending the quarter with 1,119 Company-operated stores.

John Van Heel, President and Chief Executive Officer stated, “We are pleased to report that the outperformance of our recent acquisitions and positive comparable store sales in the first quarter, combined with our continued focus on margin improvement, enabled us to deliver earnings per share at the high end of our guidance range, when adjusting for management transition costs. These positive trends have continued into July with an increase in comparable store sales of approximately 1.5% quarter-to-date and higher margins in both our tire and service categories.”

Acquisitions Update

The Company also announced today that it has signed definitive agreements to acquire 20 stores, including eight from an existing Car-X franchisee. These stores fill-in the existing markets of Michigan, Illinois and Indiana and are expected to add approximately $13 million in annualized sales, representing a sales mix of 95% service and 5% tires. Twelve of these stores will operate under the Monro name and the remaining eight will continue to operate under the Car-X brand. The acquisitions are expected to close in the second quarter of fiscal 2018 and be breakeven to diluted earnings per share in fiscal 2018.

Leadership Transition

As previously announced on June 28, 2017, the Company’s Board of Directors elected Brett Ponton as Monro’s next President and Chief Executive Officer. Mr. Ponton will join Monro as President on August 1, 2017 and assume the role of Chief Executive Officer on October 2, 2017. Mr. Ponton will succeed John Van Heel, who will serve as an advisor to Monro until March 31, 2018. Lead director Robert Mellor was also elected as independent Chairman of the Board of Directors, as Robert Gross, prior Executive Chairman, will retire from the Board and the Company at the conclusion of the annual shareholder meeting on August 15, 2017.

Company Outlook

Based on current visibility, business and economic trends, and recently completed and announced acquisitions, the Company anticipates fiscal 2018 sales to be in the range of $1.135 billion to $1.155 billion, an increase of 11% to 13% as compared to fiscal 2017 sales. In light of comparable store sales trends fiscal year-to-date, guidance for fiscal 2018 comparable store sales has been revised to an increase in the range of 1.5% to 2.5% on a 52-week basis (3.5% to 4.5% including an extra week in the fourth quarter), as compared to prior guidance of an increase of 2.0% to 4.0% on a 52-week basis (4% to 6% including an extra week in the fourth quarter).

The Company has also updated its fiscal 2018 diluted earnings per share guidance to be in the range of $2.05 to $2.20, to reflect $0.06 in incremental costs related to the management transition and the revised comparable store sales guidance. This compares to previous guidance of $2.10 to $2.30. The diluted earnings per share guidance continues to include approximately $.10 of contribution from the 53^rd week, $.15 to $.19 in accretion from recent acquisitions and is based on 33.4 million diluted weighted average shares outstanding. At the midpoint of the range, the revised guidance represents a 15% increase in diluted earnings per share, as compared to $1.85 in fiscal 2017.

For the second quarter of fiscal 2018, the Company anticipates sales to be in the range of $278 million to $285 million, representing an increase of 13% to 16%, over sales of $246 million in the second quarter of fiscal 2017. Fiscal 2018 second quarter sales guidance is based on a comparable store sales increase of 1.0% to 2.5%, as compared to a 4.3% decline in the prior year period. The Company expects diluted earnings per share for the second quarter to be in the range of $.52 to $.56, which includes $.02 of management transition costs and assumes slight accretion from recent acquisitions. This compares to diluted earnings per share of $.53 in the second quarter of fiscal 2017.

Mr. Van Heel concluded, “I am confident that our team will be able to effectively leverage Monro’s unique business model and capitalize on the significant opportunities for profitable growth both organically and through accretive acquisitions and greenfield expansion. The outlook for the industry remains positive, with the total vehicles in operation, particularly those six years old and older, set to grow significantly over the next several years. Going forward, the Company is well positioned to build on this strong foundation and deliver value to our customers, associates and shareholders.”
