FOR IMMEDIATE RELEASE

REV GROUP, INC. REPORTS FISCAL 2018 THIRD QUARTER RESULTS

Milwaukee, Wis.—(BUSINESS WIRE) — REV Group, Inc. (NYSE: REVG), a manufacturer of industry-leading specialty vehicle brands, today reported results for the three months ended July 31, 2018 (“third quarter 2018”). Consolidated net sales in the third quarter 2018 were $597.7 million, representing growth of 0.4% over the three months ended July 29, 2017 (“third quarter 2017”). The Company’s third quarter 2018 net income was $18.3 million, or $0.28 per diluted share, representing net income growth of 20.4% compared to the third quarter 2017. Adjusted Net Income² for the third quarter 2018 was $24.7 million, or $0.38 per diluted share, an increase of 12.8% compared to $21.9 million, or $0.33 per diluted share, in the third quarter 2017. Adjusted EBITDA² in the third quarter 2018 was $47.6 million, $2.1 million better than the third quarter 2017. The Company ended the quarter with total backlog of $1,276.0 million, up 0.4% sequentially, representing growth in line with historical seasonality of its businesses, and up 34.1% versus third quarter 2017.

“The availability of commercial chassis was a bigger headwind in the third quarter than previously anticipated, and we now don’t anticipate a return to normalcy until the end of the calendar year. In addition, during the quarter we experienced a significant lengthening of other material lead times creating additional production inefficiencies. Together these issues delayed product shipments beyond the quarter within all three of our segments and we expect this to continue through the fourth quarter,” commented Tim Sullivan, CEO REV Group. “In addition, certain business units including our Class A RV, specialty products, and parts business have underperformed our targets and we are taking specific actions to address these areas. We believe the material and chassis availability issues can be resolved by calendar year end. More importantly, we were able to largely mitigate the impacts of cost inflation and preserve margins in the quarter through price increases and our previously announced cost reductions.”

Mr. Sullivan added, “We remain encouraged by continued strength of orders for most of our product categories and our resulting backlogs at the end of the quarter. We have not changed our long-term objectives and believe in our opportunities for continued margin expansion in fiscal 2019 and beyond despite the current supply chain issues. In addition, our leadership position in our markets remains strong. We expect to close the year with good momentum going into fiscal 2019 supported by strong backlogs and a reduced cost infrastructure. We will continue to evaluate opportunities to drive increased returns to shareholders in the upcoming quarter and in the next fiscal year and beyond. In the third quarter 2018 we repurchased $40.7 million of our shares and our board of directors recently increased our share repurchase authorization by an additional $50 million, for a total of $55 million remaining under board authorizations.

REV Group Segment Highlights

Fire & Emergency Segment

Fire & Emergency (“F&E”) segment net sales were $238.9 million in the third quarter 2018, a decrease of $23.2 million, or 8.9%, from $262.1 million in the third quarter 2017. The decrease in net sales was primarily due to chassis supply disruptions which resulted in lower ambulance unit shipments for the quarter as well as by the timing of fire truck shipments compared to the prior year period. F&E backlog at the end of the third quarter 2018 was up 2.7% to $606.5 million compared to $590.3 million at the end of fiscal year 2017, and down per normal seasonality from $633.8 million at the end of the second quarter 2018.

F&E segment Adjusted EBITDA was $25.3 million in the third quarter 2018, a decrease of $3.7 million, or 12.8%, from $29.0 million in the third quarter 2017. The decrease in Adjusted EBITDA was due to decreased gross profit driven by a decrease in ambulance shipments partially offset by favorable selling, general and administrative expenses. Third quarter 2018 F&E segment Adjusted EBITDA margin was 10.6% of net sales compared to 11.1% in the third quarter 2017 and up sequentially from 8.6% in the second quarter 2018.

Mr. Sullivan commented, “Our backlog is healthy, and we expect to continue benefiting from positive macro trends that are driving demand for our Fire & Emergency products. We also remain encouraged by our opportunity to drive margin expansion in fiscal 2019 and over the long-term in this segment, as we anticipate profitability levels of acquired businesses will continue to improve and our recent pricing actions will offset to a greater degree our material cost increases. We believe the chassis and material lead time issues which impacted our third quarter and will continue to impact the segment in the fourth quarter should result in future earnings and cash generation when delayed shipments are fulfilled.”

Commercial Segment

Commercial segment net sales were $157.6 million in the third quarter 2018, an increase of $3.2 million, or 2.1%, from $154.4 million in the third quarter of 2017. The increase in net sales was due primarily to an increase in shuttle bus, school bus, mobility van and terminal truck units sold compared to the prior year period. Commercial sales were also negatively impacted by chassis availability in the quarter, specifically in our Bus division. Commercial backlog at the end of the third quarter was $420.0 million, an increase of 14.6% compared to $366.4 million at the end of fiscal year 2017, and up 5.7% from $397.2 million at the end of the second quarter 2018.

Commercial segment Adjusted EBITDA was $11.8 million in the third quarter 2018, a decrease of $1.1 million, or 8.5%, from $12.9 million in the third quarter 2017. This decrease was primarily due to mix as a result of reduced volumes of product lines such as transit bus units sold compared to the prior year. In addition, our specialty product lines underperformed our expectations and we are taking actions to address the underlying issues. Adjusted EBITDA margin was 7.5% of net sales in the third quarter 2018 compared to 8.4% in the third quarter 2017 and up sequentially from 6.0% in the second quarter 2018.

Mr. Sullivan commented, “We’re maintaining strong market share in school buses and have begun participating in more commercial bus activity recently. We were pleased to see sequential margin improvement in the segment during the quarter despite complications related to the availability of certain commercial chassis. We also expect the return to prior year and greater product sales volumes of both transit buses and commercial school buses in fiscal 2019 which will provide a significant tailwind to our Commercial segment profitability.”

Recreation Segment

Recreation segment net sales were $197.3 million in the third quarter 2018, an increase of $19.4 million, or 10.9%, from $177.9 million in the third quarter 2017. The increase in net sales was due to net sales attributable to our recent acquisition of Lance and increases in net sales across our brand line-up except for Class A motorhomes, which declined compared to the prior year period due to a strategic reduction in the number of models produced and the timing of new model year introductions this fiscal year. Excluding the impact of net sales from Lance, Recreation segment net sales decreased by $15.2 million compared to the prior year period, as a result of the reduction in Class A unit volume. Sales for all other Recreation segment product categories were up in the third quarter 2018 by double-digit percentages versus the same period in the prior year. Recreation segment backlog at the end of the third quarter 2018 was $249.5 million, which was up 72.3% from $144.8 million at the end of fiscal year 2017, and up 4.2% from the end of the second quarter 2018.

Recreation segment Adjusted EBITDA was $17.9 million in the third quarter 2018, an increase of $6.2 million, or 53.0%, from $11.7 million for the third quarter 2017. The increase in Adjusted EBITDA was due to the impact of the acquisition of Lance and increased profitability at our Midwest and Renegade businesses along with our Goldshield fiberglass business. Adjusted EBITDA margin improved by 250 basis points to 9.1% of net sales in the third quarter 2018 compared to 6.6% in the third quarter 2017 and up from 6.4% in the second quarter of 2018. Excluding the impact of the acquisition of Lance, Recreation segment Adjusted EBITDA increased 7.3% in the third quarter 2018 compared to the prior year period.

Mr. Sullivan commented, “We were pleased with our ability to drive margin improvement across our Recreation business lines during the third quarter despite ongoing efforts to reposition our Class A product portfolio. The strength of recent acquisitions continues to improve profitability of this segment but also highlights the benefits of our overall acquisition growth strategy. We believe the diversification of our Recreation segment will continue enabling us to participate in the stronger areas of this market and further broaden our product portfolio and value proposition for dealer partners. Additionally, we expect the Lance acquisition to help accelerate the pace of profitability improvement in the segment over the course of the next several quarters.”

Working Capital, Liquidity, and Capital Allocation

Net working capital³ for the Company at July 31, 2018 was $434.8 million compared to $299.7 million at the end of fiscal year 2017 and $358.1 million in the prior year quarter. The increase in working capital versus the prior year quarter was due to the impact of the Lance acquisition, indirect impact from the chassis availability and material lead time issues and higher seasonal fourth quarter production and shipment expectations. Per our normal seasonality, we expect net working capital to be a source of cash in our fiscal fourth quarter.

Cash and equivalents totaled $14.7 million at July 31, 2018. Net debt⁴ at July 31, 2018 was $427.0 million. As of July 31, 2018, the Company had $119.4 million available under its ABL revolving credit facility. Capital expenditures in the third quarter 2018 were $8.2 million compared to $11.8 million in the prior year quarter. During the quarter the Company repurchased a total of 2,475,967 of its own shares for $40.7 million, an average repurchase price of $16.42 per share. To date the company has repurchased a total of 2,714,514 shares for a total of $45.5 million. Shares outstanding as of July 31, 2018 were 63,191,445.

Outlook

REV has revised its full-year 2018 outlook to reflect lower-than-expected third-quarter performance and a continuation of negative factors that impacted sales and earnings during the prior two quarters through the end of the fiscal year. The Company now expects full-year 2018 results in the following ranges:

Mr. Sullivan commented, “We are disappointed with our financial results through the first three quarters of this year and our expectations today for the full fiscal year. We are focused on quickly addressing the issues which have impacted our financial performance this year and remain steadfast regarding our opportunity to grow our sales and earnings in fiscal 2019 and over the long term. The supply chain imbalances that have developed this year and were triggered by the tariff discussions will take months to work through the system, but they are not permanent, and we are very bullish on our long-term prospects. Fiscal 2019 is setting up to be a strong year, especially with the rebound we foresee in some of the higher margin businesses that have experienced lower volumes this fiscal year.”

Quarterly Dividend

Our board of directors declared a quarterly dividend for our third quarter of 2018, payable on November 30, 2018, to holders of record on October 31, 2018, 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.

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. Adjusted Net Income represents net income as adjusted for certain after-tax, non-recurring, one-time and other adjustments which we believe are not indicative of our underlying operating performance as well as for the add-back of non-cash intangible asset 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.
