ROCHESTER, N.Y. – May 18, 2017 – Monro Muffler Brake, Inc. (Nasdaq: MNRO), a leading provider of automotive undercar repair and tire services, today provides financial results for its fourth quarter and fiscal year ended March 25, 2017, as well as details pertaining to its fiscal 2018 guidance, both of which are consistent with the Company’s recent business update.

Fourth Quarter Results

Sales for the fourth quarter of fiscal 2017 increased 10.0% to $252.0 million, as compared to $229.0 million for the fourth quarter of fiscal 2016. The total sales increase for the fourth quarter of $23.0 million was due to sales from new stores of $40.8 million, including sales from recent acquisitions of $35.1 million, partially offset by a comparable store sales decrease of 8.0%, versus an increase of 0.5% in the prior year period. There was one less selling day in the current year quarter. Comparable store sales declined approximately 1% for brakes, 6% for maintenance services, 7% for front end/shocks, 8% for alignments and 11% for tires.

Gross margin decreased 310 basis points to 37.0% in the fourth quarter from 40.1% in the prior year period, primarily due to the impact of sales mix from recent acquisitions and deleverage from negative comparable store sales. On a comparable store basis, gross margin declined 40 basis points due to deleverage. Total operating expenses increased by $7.7 million to $73.1 million, or 29.0% of sales, as compared to $65.4 million, or 28.6% of sales in the prior year period. The dollar increase represents expenses from 89 net new stores as compared to the same period last year. On a comparable store basis, total operating expenses declined slightly from the prior year period due to diligent cost control.

Operating income was $20.1 million, or 8.0% of sales, as compared to $26.5 million, or 11.6% of sales in the prior year period. Interest expense was $5.5 million as compared to $4.5 million for the fourth quarter of fiscal 2016.

Net income for the fourth quarter of fiscal 2017 was $9.7 million, as compared to $13.9 million in the same period of the prior year. Diluted earnings per share for the quarter were $.29, as compared to diluted earnings per share of $.42 in the fourth quarter of fiscal 2016. Net income for the fourth quarter of fiscal 2017 reflects an effective tax rate of 34.5%, as compared to 36.5% in the prior year period.

During the fourth quarter of fiscal 2017, the Company opened 24 Company-operated locations and closed four locations, ending the quarter with 1,118 Company-operated stores. In fiscal 2017, the Company opened 105 Company-operated locations, of which 30 were greenfield locations.

Fiscal Year Results

Net sales for fiscal 2017 increased 8.3% to $1.022 billion as compared to $943.7 million for fiscal 2016. The total sales increase of $77.9 million for the fiscal year was due to an increase in sales from new stores of $124.3 million, including sales from recent acquisitions of $102.5 million, partially offset by a 4.3% comparable store sales decline versus flat comparable store sales in the prior fiscal year. Comparable store sales decreased approximately 2% for tires, 4% for maintenance services, 6% for alignments, 8% for brakes and 10% for front end/shocks.

Gross margin declined 200 basis points to 38.9% for fiscal 2017 from 40.9% in the prior fiscal year, largely due to the impact of sales mix from recent acquisitions and de-leverage from negative comparable store sales. On a comparable store sales basis, gross margin declined by 20 basis points.

Total operating expenses were $280.5 million, or 27.5% of sales, for fiscal 2017, as compared to $265.1 million, or 28.1% of sales, for the prior fiscal year. The dollar increase represents expenses from 89 net new stores as compared to fiscal 2016. Operating income for fiscal 2017 was $116.4 million, or 11.4% of sales, as compared to $120.6 million, or 12.8% of sales in fiscal 2016. Operating margin declined as a result of deleverage caused by negative comparable store sales and dilution from fiscal 2017 acquisitions. Interest expense was $19.8 million in fiscal 2017 as compared to $15.5 million in fiscal 2016.

Net income for fiscal 2017 was $61.5 million or $1.85 per diluted share, as compared to net income of $66.8 million, or $2.00 per diluted share in fiscal 2016.

John Van Heel, President and Chief Executive Officer stated, “The combination of unseasonable weather and a difficult consumer spending environment resulted in a decline in our comparable store sales, which reduced our profits for the fourth quarter and the full fiscal year. As we enter the first quarter of fiscal 2018, our comparable store sales have improved and are up quarter-to-date, led by higher average ticket. Comparable store sales for fiscal April increased approximately 3% and are up approximately 2% month-to-date in fiscal May. Thus far in the first quarter, on a comparable store basis, we are also realizing higher margins in both our tire and service categories.”

Acquisitions Update

In fiscal March 2017, the Company completed the previously announced acquisition of 16 stores from a Car-X franchisee, including 13 locations in Illinois and three in Iowa. These stores are expected to add approximately $15 million in annualized sales, representing an expected sales mix of 75% service and 25% tires, and will continue to operate under the Car-X brand.

The Company’s acquisitions completed in fiscal 2017 are expected to add $150 million in annualized sales and represent 16% in annualized sales growth over fiscal 2016. Additionally, fiscal 2017 acquisitions are expected to increase the Company’s tire purchases by approximately 25% over fiscal 2016, expanding both the Company’s tire assortment and cost competitiveness.

Cash Dividend Increased 6%

The Company also announced today that its Board of Directors has approved a $.01 increase in the Company’s cash dividend for the first quarter of fiscal year 2018 to $.18, which translates to an annual rate of $.72 per share and represents an increase of $.04 per share or 5.9% as compared to the total dividends paid in fiscal 2017.

The Company has increased its cash dividend 12 times during the 12 years since a cash dividend was first issued. 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 $.18 per share for the first quarter of fiscal 2018 will be payable on June 12, 2017 to shareholders of record as of June 2, 2017.

Company Outlook

Based on current visibility, business and economic trends, and recently completed acquisitions, the Company anticipates fiscal 2018 sales to be in the range of $1.125 billion to $1.155 billion, an increase of 10% to 13% over fiscal 2017 sales. Fiscal 2018 sales guidance assumes a comparable store sales increase of 2% to 4% on a 52-week basis (4% to 6% including an extra week in the fourth quarter).

Fiscal 2018 diluted earnings per share are expected to be in the range of $2.10 to $2.30, which represents an increase of 14% to 24% over fiscal 2017. This estimate is based on 33.4 million diluted weighted average shares outstanding. At the midpoint, this guidance represents an increase in operating margin of 70 basis points. The guidance includes approximately $.10 of contribution from the 53^rd week and $.15 to $.19 in accretion from recent acquisitions. This guidance also reflects the estimated impact of higher tire selling prices related to expected tire cost increases.

For the first quarter of fiscal 2018, the Company anticipates sales to be in the range of $270.0 million to $275.0 million and comparable store sales to increase 2.0% to 3.0%, as compared to a 6.9% decline in the prior fiscal year period. The Company expects diluted earnings per share for the first quarter to be in the range of $.52 to $.56, as compared to $.50 in the first quarter of fiscal 2017.

Mr. Van Heel concluded, “Following a year of significant acquisitions, we are entering fiscal 2018 well positioned to benefit from these recent transactions and improving sales trends, which we expect to be driven in part by higher tire average ticket. Looking ahead, we are optimistic about the opportunities we see to complete additional acquisitions, continue our greenfield expansion and benefit over the next several years from the growth in the number of vehicles six years old and older, which represent our core customer. The increase in our cash dividend announced today, the twelfth increase in 12 years, reflects the Board’s continued confidence in Monro’s long-term strategic plan and commitment to increasing shareholder returns.”
