Generac Reports Second Quarter 2017 Results

Strong shipments of home standby generators and domestic mobile products lead to overall solid organic sales growth over the prior year

WAUKESHA, WISCONSIN, (August 2, 2017) – Generac Holdings Inc. (NYSE: GNRC) (“Generac” or the “Company”), a leading global designer and manufacturer of power generation equipment and other engine powered products, today reported financial results for its second quarter ended June 30, 2017.

Second Quarter 2017 Highlights    

“We are pleased with our second quarter results with strong organic sales growth compared to the prior year leading to an improvement in overall operating earnings and cash flow,” said Aaron Jagdfeld, President and Chief Executive Officer. “Shipments of home standby generators in particular were very strong in the quarter as higher power outage activity and targeted marketing in the first half drove increased activations as every region in the US experienced solid double digit growth year over year. Demand for our mobile products domestically also continued to be much stronger as compared to the prior-year, as our rental equipment customers further replaced and upgraded their fleets during the quarter.”

Additional Second Quarter 2017 Consolidated Highlights

Residential product sales increased 9.0% to $198.1 million as compared to $181.7 million in the prior year. Commercial & Industrial (C&I) product sales improved 8.9% to $170.8 million as compared to $156.7 million in the prior year.

Gross profit margin was 34.0% compared to 33.8% in the prior-year second quarter. The prior year included $3.4 million of expense relating to the purchase accounting adjustment for the step-up in value of inventories relating to the Pramac acquisition. Excluding the impact of these expenses, gross margin in the prior year was 34.7%. The pro-forma decline in gross margin as compared to the prior year was due to a number of factors including higher commodity prices seen in prior quarters and, to a lesser extent, certain plant consolidation costs.

Operating expenses increased $2.1 million, or 2.6%, as compared to the second quarter of 2016. The increase was primarily driven by the addition of recurring operating expenses associated with the Motortech acquisition.

Cash flow from operations was $60.2 million as compared to $59.1 million in the prior year, and free cash flow was $53.7 million as compared to $52.2 million in the same period last year. The increases in cash flow were primarily driven by higher operating earnings in the current-year quarter, partially offset by a smaller benefit from working capital reduction during the current year.

Business Segment Results

Domestic Segment

Domestic segment sales increased 6.7% to $305.9 million as compared to $286.7 million in the prior-year quarter. The current-year second quarter experienced strong growth in shipments of home standby generators and mobile products. This strength was partially offset by a decline in residential portable sales due to excess levels of field inventory during the current-year quarter along with new product placement with certain retail customers in the prior-year quarter.

Adjusted EBITDA for the segment was $64.2 million, or 21.0% of net sales, as compared to $57.4 million in the prior year, or 20.0% of net sales. Adjusted EBITDA margin in the current year was positively impacted by improved overall leverage of fixed operating expenses on the organic increase in sales, partially offset by unfavorable impact from higher commodity prices seen in prior quarters.

International Segment

International segment sales, primarily consisting of C&I products, increased 10.9% to $89.5 million as compared to $80.7 million in the prior-year quarter. The increase was primarily due to the contribution from the recent acquisition of Motortech, which closed on January 1, 2017.

Adjusted EBITDA for the segment, before deducting for non-controlling interests, was $6.0 million, or 6.7% of net sales, as compared to $6.6 million, or 8.2% of net sales, in the prior year. The decline in adjusted EBITDA margin as compared to the prior year was primarily due to unfavorable foreign currency impacts and sales mix, along with higher commodity prices and increased overall operating expenses including the expansion of branch operations. These impacts were partially offset by the addition of the Motortech acquisition.

2017 Outlook Update

The Company is increasing its prior guidance for revenue growth for full-year 2017, which is primarily due to an improved outlook for domestic mobile products, as well as higher international segment sales from a stronger Euro relative to the U.S. dollar. Full year net sales are now expected to increase between 6 to 8% as compared to the prior year, with core organic growth of between 2 to 3%. As a result of an unfavorable shift in sales mix and foreign currency impacts, the Company is revising its prior guidance for net income and adjusted EBITDA margins for the full year 2017. Net income margins, before deducting for non-controlling interests, are now expected to be between 7.0 to 7.5%, while adjusted EBITDA margins, also before deducting for non-controlling interests, are now expected to be approximately 18.5% for the full year 2017.

The top-line guidance assumes no material changes in the current macroeconomic environment and also assumes a power outage severity level for the remainder of the year similar to that experienced during 2016 excluding the impact of Hurricane Matthew. Operating and free cash flow generation is expected to seasonally increase during the second half, with the conversion of adjusted net income expected to be over 90% for the full year.

Reconciliations to GAAP Financial Metrics

Adjusted EBITDA

The computation of adjusted EBITDA attributable to the Company is based on the definition of EBITDA contained in Generac's credit agreement dated as of May 31, 2013, as amended. To supplement the Company's condensed consolidated financial statements presented in accordance with U.S. GAAP, Generac provides a summary to show the computation of adjusted EBITDA, which excludes the impact of non-controlling interests, taking into account certain charges and gains that were recognized during the periods presented.

Adjusted Net Income

To further supplement Generac's condensed consolidated financial statements presented in accordance with U.S. GAAP, the Company provides a summary to show the computation of adjusted net income attributable to the Company. Adjusted net income attributable to the Company is defined as net income before non-controlling interests and provision for income taxes adjusted for the following items: cash income tax expense, amortization of intangible assets, amortization of deferred financing costs and original issue discount related to the Company's debt, intangible impairment charges, certain transaction costs and other purchase accounting adjustments, losses on extinguishment of debt, business optimization expenses, certain other non-cash gains and losses, and adjusted net income attributable to non-controlling interests.

Free Cash Flow

In addition, we reference free cash flow to further supplement Generac's condensed consolidated financial statements presented in accordance with U.S. GAAP. Free cash flow is defined as net cash provided by operating activities less expenditures for property and equipment and is intended to be a measure of operational cash flow taking into account additional capital expenditure investment into the business.

The presentation of this additional information is not meant to be considered in isolation of, or as a substitute for, results prepared in accordance with U.S. GAAP.  Please see our SEC filings for additional discussion of the basis for Generac's reporting of Non-GAAP financial measures, which includes why the Company believes these measures provide useful information to investors and the additional purposes for which management uses the non-GAAP financial information.
