FOR IMMEDIATE RELEASE

REV Group. Inc. Reports Fiscal First Quarter 2017¹ Results and Provides Full-Year Guidance

Milwaukee, Wis.—(BUSINESS WIRE)—

REV Group, Inc. (NYSE: REVG) today reported results for the three months ended January 28, 2017 (“first quarter 2017”). Consolidated net sales in the first quarter of 2017 were $442.9 million, growing 18.8% over the three months ended January 30, 2016 (“first quarter 2016”). The increase was driven predominately by strong growth in the Fire & Emergency and Recreation segments. REV Group also had strong growth in first quarter 2017 in aftermarket parts sales, which grew 10.4% over first quarter 2016 as the Company continues to execute on its growth strategies.

The Company’s first quarter 2017 net loss was $13.3 million, or ($0.26) per diluted share. The first quarter 2017 net loss was negatively impacted by a number of one-time items which included a $25.5 million before-tax stock compensation charge, due to our initial public offering (“IPO”), for stock options awarded prior to the IPO. REV Group’s IPO took place on January 27, 2017 and closed on February 1, 2017. Adjusted Net Income for the first quarter 2017 was $5.7 million, or $0.11 per diluted share, compared to $3.9 million, or $0.07 per diluted share, in the first quarter fiscal 2016.

Adjusted EBITDA in the first quarter 2017 was $21.1 million, representing growth of 40.4% over Adjusted EBITDA of $15.0 million in the first quarter 2016. The increase in Adjusted EBITDA was driven by a number of factors including higher vehicle sales, strong aftermarket parts sales, lower discounts for certain vehicle categories, and ongoing procurement and production cost optimization efforts.

REV Group, Inc. President and CEO, Tim Sullivan said “We are pleased to report strong results for our initial quarter as a public company. Our first quarter 2017 results demonstrate solid execution of the ongoing plan to scale our 27 market-leading specialty vehicle brands and meet our long-term target of generating company-wide Adjusted EBITDA margins of 10%. Our strategic efforts to increase profitability were evident in our results. Sales growth was driven by strong end-market demand, gains in market share and our new product initiatives. Our strong results serve as a testament to the hard work of our employees who are executing our strategies on a daily basis.”

REV Group Segment Highlights

Fire & Emergency – Fire & Emergency (“F&E”) net sales for the first quarter 2017 were $185.4 million representing growth of 44.4% over the prior year period. Sales growth was driven, in part, by the acquisition of Kovatch Mobile Equipment (“KME”) in April of 2016. Excluding the results of KME, F&E segment revenues grew 16.5% over the prior year period primarily resulting from strong growth in ambulance vehicle sales and higher sales generated at our F&E Regional Technical Centers (“RTC”). F&E backlog at the end of the first quarter 2017 was up 4.8% to $577.1 million compared to $550.8 million at the end of fiscal year 2016.

F&E segment adjusted EBITDA³ was $16.7 million in the first quarter 2017 which was a growth of 9.0% compared to $15.3 million in the first quarter 2016. F&E Adjusted EBITDA was driven during the first quarter 2017 by higher vehicle sales, and growth in RTC and aftermarket parts revenues. First quarter F&E Adjusted EBITDA margin was 9.0% of net sales compared to 11.9% in the first quarter 2016. The decline in margin percentage is attributable to the impact of the KME acquisition. We are pleased to report that we are on schedule with the KME integration and plan to increase KME profitability as the year progresses and in line with our E-ONE brand over time.

Commercial – Commercial segment net sales for the first quarter 2017 were $130.2 million, which were down 7.3% compared to the prior year period. This decrease was in line with our expectations driven by lower sales in certain product categories as we are focusing on sales mix and are being more selective about which sales opportunities we pursue. End markets in all our Commercial product categories remain strong and growing versus the prior year. Commercial segment backlog grew slightly to $227.5 million from $226.1 million at the end of fiscal year 2016.

Commercial segment Adjusted EBITDA was $8.2 million in the first quarter 2017 compared to $5.2 million in the first quarter 2016, which is growth of 57.9% year-over-year. Adjusted EBITDA margin was 6.3% of net sales in the first quarter 2017 compared to 3.7% in the first quarter 2016. Adjusted EBITDA growth in the first quarter 2017 was strong for all Commercial product categories, with segment profitability improvement during the quarter driven by less discounting, lower fixed costs, procurement and product initiatives, and growing aftermarket parts revenues.

Recreation – The Recreation segment grew first quarter 2017 net sales to $128.9 million, representing growth of 21.0% over the prior year period. Segment growth was partially driven by the acquisition of Renegade RV (“Renegade”) which was completed on December 30, 2016. Revenue growth excluding Renegade was also strong at 16.1% as the RV end markets continue to grow and the segment benefited from the growth of its Class C line of products which were reintroduced in the middle of 2016. Recreation segment backlog at the end of the first quarter 2017 was $107.7 million, which was up 33.9% from $80.4 million at the end of fiscal year 2016. Excluding the backlog from the newly acquired Renegade, Recreation backlog at the end of the first quarter was down 9.0% versus the prior fiscal year-end.

Recreation segment Adjusted EBITDA grew in the first quarter 2017 to $2.8 million compared to a loss of $1.8 million in the first quarter 2016. Adjusted EBITDA margin in the first quarter was 2.2% of net sales compared to negative 1.7% in the first quarter 2016. The strong 390 basis point expansion in profitability is attributable to lower discounting, a higher mix of Class A diesel units and benefits from our ongoing procurement and operating initiatives.

Working capital, liquidity and capital allocation – Net working capital⁴ for the Company at January 28, 2017 was $251.6 million compared to $187.3 million at the end of fiscal 2016. This represents a normal seasonal increase in net working capital consistent with prior years. Cash and equivalents totaled $15.1 million at the end of the first quarter 2017. Total debt at the end of the first quarter 2017 was $336.0 million and the Company had $134.2 million available under its existing credit facility as of January 28, 2017.

Subsequent to the end of the first quarter, the Company completed its initial public offering and used the net proceeds of $254.4 million to pay off the remaining outstanding balance of its Senior Notes, including accrued interest and call premium, and a portion of the then outstanding borrowings on its revolving credit facility. Net debt outstanding on the Company’s revolving credit facility at the end of the first quarter 2017, assuming the use of IPO proceeds to pay-down debt, was approximately $83.0 million. First quarter capital expenditures of $18.6 million were greater than the expected quarterly run rate for the rest of the year as spending was front-end loaded for the current year. The Company expects full fiscal year 2017 capital expenditures to approximate $40 to $45 million.

Quarterly Dividend – Our board of directors declared a quarterly dividend for our second quarter of fiscal 2017, payable on May 31, 2017, to holders of record on April 30, 2017, in the amount of $0.05 per share of common stock, which represents $0.20 per share of common stock on an annualized basis.

Fiscal 2017 Full Year Guidance – “Today we introduce our REV Group full-year fiscal 2017 outlook for net sales and Adjusted EBITDA. We expect full-year fiscal 2017 revenues of $2.225 to $2.325 billion, net income of $40 to $43 million and Adjusted EBITDA of $150 to $155 million,” said Sullivan. “This outlook does not include any impact from potential future acquisitions.”

The Company’s policy will be to update or affirm its full year financial guidance on a quarterly basis going forward.

Note Regarding Non-GAAP Measures

The Company reports its financial results in accordance with U.S. generally accepted accounting principles (“GAAP”). However, management believes that the evaluation of our ongoing operating results may be enhanced by a presentation of Adjusted EBITDA and Adjusted Net Income, which are non-GAAP financial measures. Adjusted EBITDA represents net income before interest expense, income taxes, depreciation and amortization as adjusted for certain non-recurring, one-time and other adjustments which we believe are not indicative of our underlying operating performance and Adjusted Net Income represents net income as adjusted for certain after-tax, non-recurring, one-time and other adjustments which the Company believes are not indicative of its underlying operating performance as well as for the add-back of certain non-cash intangible amortization and stock-based compensation.

The Company believes that the use of Adjusted EBITDA and Adjusted Net Income provide additional meaningful methods of evaluating certain aspects of its operating performance from period to period on a basis that may not be otherwise apparent under GAAP when used in addition to, and not in lieu of, GAAP measures. A reconciliation of Adjusted EBITDA and Adjusted Net Income to the most closely comparable financial measures calculated in accordance with GAAP is included in the financial appendix of this news release.
