Generac Reports Second Quarter 2018 Results

Record second quarter results driven by strong, broad-based demand and margin growth; Raising outlook for 2018

WAUKESHA, WISCONSIN (August 1, 2018) – 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, 2018.

Second Quarter 2018 Highlights

“Our second quarter results further demonstrate the tremendous earnings power of Generac as solid execution across our entire business helped drive a 300 basis point expansion in EBITDA margins over the prior year,” said Aaron Jagdfeld, President and Chief Executive Officer. “We continue to see robust demand across all of our end markets and geographies, with particular strength coming from residential products as power outages over the last twelve months have been well above the long-term average. Global interest for our C&I mobile and stationary products has also been strong primarily driven by an increase in telecom, healthcare and other large projects, as well as the continued investment in fleet equipment by our rental account customers. Lastly, on June 1^st, we closed on the acquisition of Selmec, further expanding our presence in the important Latin American backup power market.”

Additional Second Quarter 2018 Consolidated Highlights

Residential product sales increased 24.1% to $246.4 million as compared to $198.5 million in the prior year. C&I product sales increased 26.9% to $215.6 million as compared to $169.9 million in the prior year, with core sales growth of approximately 21%.

Gross profit margin improved 190 basis points to 35.6% as compared to 33.7% in the prior-year second quarter. The increase reflected better leverage of fixed manufacturing costs on the significant increase in sales, a more favorable pricing environment, and focused initiatives to improve margins. These items were partially offset by general inflationary pressures from higher commodities, currencies, wages and logistics costs.

Operating expenses increased $9.7 million, or 11.9%, as compared to the second quarter of 2017. The increase was primarily driven by higher variable operating expenses given the higher sales volumes, an increase in employee costs including additional incentive compensation, and increased International operating expenses given the stronger Euro. These items were partially offset by lower promotional costs as well as lower intangible amortization expense.

Consolidated Adjusted EBITDA, before deducting for non-controlling interests, improved to $102.2 million, or 20.7% of net sales, as compared to $69.7 million, or 17.7% of net sales, in the prior year.

Cash flow from operations was $50.7 million as compared to $59.5 million in the prior-year second quarter, and free cash flow was $45.9 million as compared to $53.7 million in the same quarter last year. The year-over-year decline in second quarter cash flow reflected increased working capital investment driven by organic sales growth and the replenishment of inventory levels in anticipation of the summer storm season.

The current year earnings per share calculation of $0.82 includes the impact of a $2.3 million adjustment to increase the value of the redeemable noncontrolling interest for the Pramac acquisition, resulting in a $0.04 reduction in earnings per share. Under U.S. GAAP accounting rules, any adjustments to the redemption value are recorded directly to retained earnings. However, the redemption value adjustments are required to be reflected in the earnings per share calculation as detailed in the accompanying reconciliation schedules.

On January 1, 2018, the Company adopted Accounting Standards Update 2014-09, Revenue from Contracts with Customers, and all related amendments, commonly known as the “new revenue recognition standard”. The full retrospective method was elected under this standard, which requires application to all periods presented. As a result, the prior-year 2017 results have been restated accordingly. However, the adoption of this standard did not have a material impact on the Company’s financial statements.

Business Segment Results

Domestic Segment

Domestic segment sales increased 24.8% to $381.0 million as compared to $305.4 million in the prior-year quarter. The current-year quarter continued to experience strong growth in shipments of home standby and portable generators and also benefitted from robust C&I shipments driven by mobile products fleet replacement and strength in stationary generators through national accounts. Increased service part sales also contributed to the year-over-year growth.

Adjusted EBITDA for the segment was $90.6 million, or 23.8% of net sales, as compared to $63.7 million in the prior year, or 20.9% of net sales. Adjusted EBITDA margin in the current year benefitted from improved overall operating leverage on the higher organic sales volumes, a favorable pricing environment, lower promotional costs, and focused margin improvement initiatives. These benefits were partially offset by an increase in employee costs, including higher incentive compensation, and general inflationary pressures.

International Segment

International segment sales increased 27.3% to $113.9 million as compared to $89.5 million in the prior-year quarter, including $4.0 million of contribution from the Selmec acquisition. Core sales growth was approximately 16%, primarily due to broad-based growth of C&I products across Europe, Asia and Latin America.

Adjusted EBITDA for the segment, before deducting for non-controlling interests, improved to $11.6 million, or 10.2% of net sales, as compared to $6.0 million, or 6.7% of net sales, in the prior year. The improvement was primarily due to increased leverage of fixed operating costs on the higher organic sales and favorable mix. These favorable impacts were partially offset by higher commodity prices, along with the expansion of certain branch operations.

Updated 2018 Outlook

The Company is increasing its prior guidance for revenue growth for full-year 2018 due to improving end-market conditions and the closing of the Selmec acquisition. Full year net sales are now expected to grow between 13 to 14% over the prior year, which is an increase from the 6 to 8% growth previously expected. Core sales growth is expected to be approximately 10%, which is an increase from the 5 to 6% growth previously expected. This top-line guidance assumes no “major” outage events and a baseline power outage severity level similar to the longer-term average for the remainder of the year. Should the baseline power outage environment in 2018 be higher, or if there is a “major” event during the year, the Company could exceed these expectations.

Given the increase in net sales guidance, net income margins, before deducting for non-controlling interests, are now expected to be approximately 10.5% for the full-year 2018, which is an increase from the 9.5 to 10.0% guidance previously expected. Adjusted EBITDA margins, also before deducting for non-controlling interests, are now expected to be approximately 20.0% for the year, up from the prior 19.0 to 19.5% guidance.

Operating and free cash flow generation is expected to remain strong, with the conversion of adjusted net income to free cash flow still forecasted to be over 90%.

Non-GAAP Financial Metrics

Core Sales

The Company references core sales to further supplement Generac's condensed consolidated financial statements presented in accordance with U.S. GAAP. Core sales excludes the impact of acquisitions and fluctuations in foreign currency translation. Management believes that core sales facilitates easier and more meaningful comparison of net sales performance with prior and future periods.

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, plus proceeds from beneficial interests in securitization transactions, 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.
