FOR IMMEDIATE RELEASE

REV Group, Inc. Reports Strong Third Quarter 2017 Results, Reaffirms Full-Year 2017 Guidance

REV also Announces Collaboration with Ford, Official Award of the Los Angeles County Transit Bus Contract, and Acquisition of AutoAbility

Milwaukee, Wis.—(BUSINESS WIRE)—

REV Group, Inc. (NYSE: REVG) today reported results for the three months ended July 29, 2017 (“third quarter 2017”). Consolidated net sales in the third quarter of 2017 were $595.6 million, growing 12.8% over the three months ended July 30, 2016 (“third quarter 2016”). This increase was driven by strong growth in the Fire & Emergency and Recreation segments, offset slightly by the impact of a chassis recall, which delayed shipments in both the Fire & Emergency and Commercial segments. The sanctioned repair for these recalled chassis is being implemented and the impacted REV vehicle conversions will be shipped in REV’s fourth quarter. Year-to-date consolidated net sales were $1.6 billion for the nine months ended July 29, 2017, which was an increase of 14.7% over the first nine months of fiscal 2016.

The Company’s third quarter 2017 net income was $15.2 million, or $0.23 per diluted share. Adjusted Net Income¹ for the third quarter 2017 was $21.9 million, or $0.33 per diluted share, which grew 36.3% compared to $16.0 million, or $0.31 per diluted share, in the third quarter 2016 (third quarter 2017 diluted earnings per share is calculated using 14.0 million more shares outstanding than the prior year quarter). Net income for the first nine months of 2017 was $8.7 million, or $0.14 per diluted share due to several one-time expense items, the largest of which related to our IPO and subsequent debt refinancings. Year-to-date Adjusted Net Income¹ was $46.7 million for the first nine months of 2017 compared to $34.2 million for the first nine months of 2016, which represents an increase of 36.4% resulting from higher earnings from operations as well as lower interest expense.

Adjusted EBITDA¹ in the third quarter 2017 was $45.5 million, representing growth of 35.9% over Adjusted EBITDA of $33.5 million in the third quarter 2016. A number of factors including increased vehicle sales, ongoing procurement and production cost optimization initiatives, strategic pricing actions, and the impact of acquisitions drove the higher Adjusted EBITDA in the quarter. For the nine months ended July 29, 2017, consolidated Adjusted EBITDA was $104.1 million, which reflects a 28.8% increase over the same period in 2016.

REV Group, Inc. President and CEO, Tim Sullivan said, “We are pleased to report our third straight quarter of strong earnings as a public company. The quarter was one of significant progress where we both delivered significant growth in net sales and EBITDA as well as made anticipated progress on many of our longer-term growth strategies in parts and service, operational and commercial excellence, new product introductions, and value creating capital allocation. Both our Fire & Emergency and Recreation segments performed very well this quarter and continue to have strong outlooks. Within our Commercial segment, we are continuing our focus on driving profitability and we are encouraged by growth in our backlog over last quarter as well as the LA County win, which will benefit future fiscal years. We expect this segment to return to growth in the fourth quarter. The supplier-initiated chassis recall during our third quarter shifted revenues out a bit, however we nevertheless performed strongly against our consolidated EBITDA expectations for the quarter due to the strength of our Fire & Emergency and Recreation segments. Looking ahead to the fourth quarter, parts to repair the vehicles impacted by the chassis recall are now available and we are again able to ship the impacted vehicles.” In addition, Sullivan stated, “Through the first nine months of the year, we are on track with our expectations for full-year 2017 earnings and therefore we are reaffirming previous guidance for the full year. In summary, it was a strong quarter and we continue to make incremental progress towards our enterprise-wide EBITDA margin goal as well as our organic and inorganic growth objectives.”

REV Group also reported that effective September 5, 2017, REV established a collaborative connection with Ford Motor Company dealers to provide our dealers with a complete catalog of genuine Ford chassis parts through its REV Parts Division to all of REV’s dealers. This access to Ford parts cataloging information allows REV dealers to order genuine Ford chassis parts through REV’s online parts system for a complete range of REV vehicle brands built on Ford chassis. REV Group, Inc. President and CEO, Tim Sullivan commented, “Our connection with Ford Motor Company dealers to provide genuine OEM-certified chassis parts is a key step towards our broader strategy of achieving our commitment to offer our dealers and end-user customers industry-leading OEM parts quality and availability.”

REV Group Segment Highlights

Fire & Emergency – Fire & Emergency (“F&E”) segment net sales were $262.1 million for the three months ended July 29, 2017, an increase of $43.9 million, or 20.1%, from $218.1 million for the three months ended July 30, 2016. Net sales of fire apparatus increased due to increased unit sales in the segment’s existing fire businesses, sales from the acquisition of Ferrara in April 2017, and a greater mix of higher content fire vehicles, compared to the prior year period. Net sales of ambulances increased compared to the prior year period due to increased unit volumes and a greater mix of higher content Type I and Type III vehicles. Excluding the impact of the Ferrara acquisition, F&E net sales increased 6.1% in the third quarter 2017 versus the third quarter 2016.

F&E net sales for the first nine months of 2017 were $666.5 million, which was an increase of 27.2% over $524.0 million for the same period in 2016. F&E backlog at the end of the third quarter 2017 was up 5.4% to $580.6 million compared to $550.8 million at the end of fiscal year 2016. Excluding the impact of acquisitions year-to-date, F&E segment net sales increased 5.8% in the first nine months of 2017 compared to the same period in 2016.

F&E segment Adjusted EBITDA² was $29.1 million in the third quarter 2017 which represented growth of 52.4% compared to $19.1 million in the third quarter 2016. F&E Adjusted EBITDA growth was driven by increased vehicle sales, procurement and productivity initiatives, pricing actions, operational improvements at KME, and the impact of the acquisition of Ferrara. Excluding the impact of Ferrara, third quarter Adjusted EBITDA increased 42.8% in 2017 versus the third quarter of 2016. Third quarter 2017 F&E Adjusted EBITDA margin was 11.1% of net sales compared to 8.7% in the third quarter 2016 partially due to the benefit from the integration initiatives at KME, among other items.

Year-to-date 2017 Adjusted EBITDA in the F&E segment increased 25.7% to $70.2 million versus $55.9 million for the first nine months of 2016. Excluding the impact of acquisitions year-to-date, F&E segment Adjusted EBITDA increased 19.9% in 2017 compared to 2016.

Commercial – Commercial segment net sales for the third quarter 2017 were $154.4 million, which were down 15.6% compared to the prior year period. This decrease was driven by lower sales in certain of our bus product categories impacted by the aforementioned chassis recall and more generally, as we continue to be more selective about which sales opportunities we pursue. We are also still scaling up our mobility product lines after a production plant relocation in that product segment.

Net sales in the Commercial segment for the first nine months of 2017 were $444.2 million versus $499.8 million in the first nine months of 2016, which was a decrease of 11.1%. Commercial backlog grew in the third quarter 2017 by 5.8% to $254.8 million at July 29, 2017, compared to the end of the second quarter 2017, and grew 12.7% from the end of 2016. We have seen a significant increase in backlog in our Commercial segment this quarter as we start to see the benefits of our newly rolled out Platinum Dealer program, among other initiatives, and this backlog does not yet include any impact of the Los Angeles County transit bus contract award described in this release.

Commercial segment Adjusted EBITDA was $12.9 million in the third quarter 2017 compared to $17.1 million in the third quarter 2016. Adjusted EBITDA margin was 8.3% of net sales in the third quarter 2017 compared to 9.3% in the third quarter 2016. Adjusted EBITDA and Adjusted EBITDA margin declined in the third quarter of 2017 primarily due to the net sales decline described above.

Year-to-date 2017 Adjusted EBITDA in the Commercial segment decreased 4.2% to $35.7 million from $37.3 million in the first nine months of 2016, but Adjusted EBITDA margin as a percent of net sales for the first nine months of 2017 was 8.0% compared to 7.5% for the first nine months of 2016.

Subsequent to the end of the third quarter, the Los Angeles County Metropolitan Transportation Authority officially awarded REV’s subsidiary, Eldorado National California (“ENC”), the contract to supply 295 40-foot CNG powered transit buses. The contract also includes a provision for an additional 305 buses, for a total of 600 buses over a 5-year period. Along with related optional vehicle features, spare parts and training, this full contract is expected to be worth over $400 million in revenue over the contract period. This award was previously announced but was subject to certain administrative processes, including an award protest. These processes are now completed resulting in the award of the final contract and purchase order to ENC for the first 295 buses.

The Commercial segment also announced the acquisition of AutoAbility on September 6^th, 2017. AutoAbility is a best-in-class mobility van “upfitter” that specializes in the manufacture of rear-access, wheelchair-accessible vehicles. AutoAbility is headquartered in Clarkston, MI and is supported by a network of 56 dealers in 74 locations throughout the United States. AutoAbility has annual revenue of approximately $8 million.

Recreation – The Recreation segment grew net sales to $177.9 million in the third quarter 2017, representing an increase of 39.9% over the prior year period. Recreation segment sales growth was partially driven by the acquisition of Renegade RV (“Renegade”) and Midwest Automotive Designs (“Midwest”) which were completed on December 30, 2016 and April 13, 2017, respectively. Recreation net sales excluding the acquisitions of Renegade and Midwest increased 9.3% during the quarter due to increased unit sales volumes and higher average selling prices. In addition to the growth in unit sales for the segment’s Class A coaches, the segment is also benefiting from expansion of its Class C line of products as well as overall growth in its end markets.

Recreation net sales for the nine months ended July 29, 2017 were $470.9 million, which was an increase of 31.7% over net sales of $357.5 million for the first nine months of fiscal 2016. Excluding acquired companies, year-to-date Recreation net sales increased 13.0% compared to the same period in 2016. Recreation segment backlog at the end of the third quarter 2017 was $116.2 million, which was up 44.4% from $80.4 million at the end of fiscal year 2016 and up 3.1% sequentially from $112.7 million at the end of the second quarter 2017.

Recreation segment Adjusted EBITDA grew 99.4% in the third quarter 2017 to $11.7 million compared to $5.8 million in the third quarter 2016. Adjusted EBITDA margin in the third quarter grew 195 basis points to 6.5% of net sales compared to 4.6% in the third quarter 2016. The strong expansion in profitability is attributable to reduced discounting and continued benefit from our ongoing procurement, cost of quality and other operating initiatives. Excluding the impact of acquisitions, Recreation Adjusted EBITDA in the third quarter 2017 increased 35.4% compared to the third quarter 2016.

Year-to-date 2017 Adjusted EBITDA in the Recreation segment was $21.7 million, which was a 216.8% increase versus the first nine months of 2016. Adjusted EBITDA in the Recreation segment, excluding the acquisitions of Renegade and Midwest increased 118.6% in the first nine months of 2017 compared to the same period in 2016.

Working capital, liquidity and capital allocation – Net working capital³ for the Company at July 29, 2017 was $358.1 million compared to $187.3 million at the end of fiscal 2016. This increase versus prior fiscal year-end includes the impact of the acquisitions of Renegade, Midwest and Ferrara and also represents a normal seasonal increase in net working capital consistent with prior years. Cash and equivalents totaled $14.1 million at the end of the third quarter 2017. Net debt at the end of the third quarter 2017 was $286.0 million (net of deferred financing costs) and the Company had $115.9 million available under its ABL revolving credit facility as of July 29, 2017. Consistent with prior years seasonality, the Company expects net working capital to meaningfully decrease in the fourth quarter. Capital expenditures in the third quarter and year-to-date through July 29, 2017 were $12.7 million and $49.9 million, respectively.

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

Fiscal 2017 Full Year Guidance – “We are reaffirming our REV Group full-year 2017 outlook as we head into our fourth quarter. We expect full-year 2017 revenues of $2.3 to $2.4 billion and Adjusted EBITDA of $157 to $162 million. We are also reaffirming our expectation for full year 2017 net income to be in the range of $36 to $39 million,” said Sullivan. “This outlook does not include any impact from potential additional future acquisitions or the pro forma impact of any acquisitions prior to their purchase by REV Group.”

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.
