FOR IMMEDIATE RELEASE

MONRO MUFFLER BRAKE, INC. PROVIDES BUSINESS UPDATE

AND ANNOUNCES CONFERENCE CALL AND WEBCAST OF FISCAL 2017 FOURTH

QUARTER RESULTS

ROCHESTER, N.Y. – May 4, 2017 – Monro Muffler Brake, Inc. (Nasdaq: MNRO), a leading provider of automotive undercar repair and tire services, today provided a business update for its fiscal 2017 fourth quarter ended March 25, 2017 and guidance for its full year fiscal 2018.

For the fourth quarter of fiscal 2017, total sales were approximately $252 million, a 10% increase over sales in the prior year quarter of $229 million, despite an 8% decline in comparable store sales and one less selling day in the quarter. As a result of the comparable store sales decline, the Company now expects diluted earnings per share for the fourth quarter to be $.29. The decline in comparable store sales was largely driven by a decline in tires sales, particularly in the Northeast and North central regions of the country, which were negatively impacted by weather.

For fiscal 2017, total sales were $1.022 billion, an 8% increase over sales in the prior year of $944 million, despite a comparable store sales decline of 4.3%. The Company now expects diluted earnings per share for fiscal 2017 of $1.85.

During the fourth quarter of fiscal 2017, the Company completed the previously announced acquisition of 16 Car-X stores in Illinois and Iowa, which represent annualized sales of approximately $15 million.

John Van Heel, President and Chief Executive Officer stated, “We believe our fiscal 2017 comparable store sales decline is a reflection of the negative impact of unseasonable weather on our business, as well as the challenging economic conditions facing our customers. In fiscal 2017, we continued to leverage our increasing scale to lower our tire costs, while effectively controlling our operating expenses. In this difficult environment, we also capitalized on attractive acquisition opportunities, completing transactions representing approximately $150 million in annualized sales or 16% annualized sales growth. Quarter-to-date in fiscal 2018, our comparable store sales have improved and are up approximately 3%. We expect these early, positive trends, combined with contributions from our recent acquisitions and an extra week in fiscal 2018, to be positive drivers of earnings in the new fiscal year.”

Based on current visibility and recently completed acquisitions, the Company anticipates that its fiscal 2018 diluted earnings per share will be between $2.10 to $2.30, which represents an increase of 14% to 24%, over the prior fiscal year. The guidance is based on an expected fiscal 2018 comparable store sales increase of 2% to 4% on a 52-week basis (4% to 6% including an extra week in the fourth quarter). This guidance reflects the estimated impact of higher tire selling prices related to expected tire cost increases. Fiscal 2018 diluted earnings per share guidance also includes approximately $.10 of contribution from the 53^rd week and $.15 to $.19 in accretion from recent acquisitions.

The Company will release its complete fourth quarter and full year fiscal 2017 earnings on May 18, 2017. The Company will host a conference call and audio webcast on Thursday May 18, 2017 at 11:00 a.m. Eastern Time.
