Generac Reports Record First Quarter 2021 Results

2021 outlook substantially increased due to broad-based strength across the business driven by further acceleration of residential product demand, recovering C&I markets, and strong operational execution

WAUKESHA, WISCONSIN (April 29, 2021) – Generac Holdings Inc. (NYSE: GNRC) (“Generac” or the “Company”), a leading global designer and manufacturer of energy technology solutions and other power products, today reported financial results for its first quarter ended March 31, 2021 and provided an update on its outlook for the full year 2021.

First Quarter 2021 Highlights

“Our first quarter results continue to demonstrate the power of Generac's business model and the fantastic execution by our team as our revenue grew at a tremendous 70% rate to over $800 million, driving a significant increase in adjusted EBITDA margins. The revenue performance represents an all-time record despite the seasonally lower first-quarter time period,” said Aaron Jagdfeld, President and Chief Executive Officer. “Growth was broad based led by a dramatic increase for home standby generators that more than doubled compared to prior year given the powerful mega trends that are driving incredible demand for these products.”

Jagdfeld continued, “Shipments of our PWRcell® energy storage systems also grew at a significant rate as compared to the prior year, and with the considerable momentum we have in the marketplace, we are increasing our outlook for these products for the remainder of the year. Shipments of C&I products returned to growth in the quarter, increasing at a strong rate as demand is recovering at a faster pace than previously expected across a number of markets and geographies. With the impact from the major outages in Texas along with further capacity expansion actions for home standby, and with demand strengthening broadly across the rest of the business, we are substantially increasing our full year revenue and earnings outlook for 2021.”

Additional First Quarter 2021 Consolidated Highlights

Gross profit margin improved 370 basis points to 39.9% compared to 36.2% in the prior-year first quarter. The increase was primarily driven by favorable sales mix from significantly higher shipments of residential products, along with improved pricing and overhead absorption from higher sales volumes. These favorable impacts were partially offset by the onset of higher input costs primarily relating to raw materials, labor, freight and logistics costs.

Operating expenses increased $23.2 million, or 21.2%, as compared to the first quarter of 2020. The increase was primarily driven by higher variable expenses from the significant increase in sales volumes, higher employee costs and incentive compensation, and the impact of acquisitions. These increases were partially offset by a reduction in controllable operating expenses.

Provision for income taxes for the current year quarter was $35.4 million, or an effective tax rate of 19.1%, as compared to $9.4 million, or a 17.9% effective tax rate, for the prior year. The increase in effective tax rate was primarily due to the significant increase in the mix of domestic pretax income in the current year.

Business Segment Results

Domestic Segment

Domestic segment sales increased 84.2% to $692.7 million as compared to $376.0 million in the prior year quarter, with the impact of acquisitions contributing approximately 2.0% of the revenue growth for the quarter. The core sales growth was primarily driven by a significant increase in shipments of residential products highlighted by home standby and portable generators. In addition, PWRcell® energy storage systems experienced healthy growth as the Company continues to expand in the clean energy market, and shipments of chore products also improved at a strong rate as compared to the prior year. This was supplemented by a return to growth for C&I products which was led by a substantial increase in shipments to telecom national account customers compared to the prior year.

Adjusted EBITDA for the segment was $207.1 million, or 29.9% of net sales, as compared to $82.8 million in the prior year, or 22.0% of net sales. This margin increase was driven by favorable sales mix, improved pricing and higher operating leverage from the substantial revenue growth for the segment during the quarter.

International Segment

International segment sales increased 14.8% to $114.7 million as compared to $99.9 million in the prior year quarter. Core sales, which excludes the favorable impact of currency, increased 9.6% compared to the prior year. The growth for the segment was due to an increase in market activity primarily in the European region that is now recovering from the impact of the COVID-19 pandemic which began during the first quarter of the prior year.

Adjusted EBITDA for the segment, before deducting for noncontrolling interests, was $7.1 million, or 6.2% of net sales, as compared to $3.3 million, or 3.3% of net sales, in the prior year. The improvement in margin was due to the combination of favorable sales mix, improved operating leverage on the higher sales volumes, and a reduction in certain controllable operating expenses.

Updated 2021 Outlook

The major outages in Texas during the first quarter have led to an acceleration in demand and backlog for home standby generators from the already elevated levels that existed prior to this event. This has resulted in a further increase in capacity expansion plans and is leading to a significant increase in the shipment outlook for these products for the full-year 2021. Also contributing to the improved outlook for residential products is a notable increase in portable generator shipments, along with higher demand for PWRcell® energy storage systems due to further progress in building out distribution partners in this overall expanding market. The outlook for C&I products has also improved considerably due to a broad based rebound in demand highlighted by a significant pickup in activity from telecom national account customers, and overall stronger outlooks for domestic and international markets.

As a result of these factors, the Company is increasing its full-year 2021 net sales growth guidance to now be approximately 40 to 45% compared to the prior year, which includes only approximately 2% of favorable impact from acquisitions and foreign currency. This is an increase from the as-reported growth guidance of 25 to 30% previously expected.

Net income margin, before deducting for non-controlling interests, is now expected to be approximately 16.0 to 17.0% for the full-year 2021, which is an increase from the prior expectation of between 15.0 to 16.0%. The corresponding adjusted EBITDA margin is now expected to be approximately 24.5 to 25.5%, which is an increase from the 24.0 to 25.0% previously expected.

Operating and free cash flow generation is still expected to be strong, with the conversion of adjusted net income to free cash flow expected to be approximately 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 and adjusted EBITDA margin 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 noncontrolling 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 noncontrolling 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.
