Certain statements contained in this news release, as well as other information provided from time to time by Generac Holdings Inc. or its employees, may contain forward-looking statements that involve risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements. Forward-looking statements give Generac’s current expectations and projections relating to the Company’s financial condition, results of operations, plans, objectives, future performance and business. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as “anticipate,” “estimate,” “expect,” “forecast,” “project,” “plan,” “intend,” “believe,” “confident,” “may,” “should,” “can have,” “likely,” “future,” “optimistic” and other words and terms of similar meaning in connection with any discussion of the timing or nature of future operating or financial performance or other events.

Any such forward-looking statements are not guarantees of performance or results, and involve risks, uncertainties (some of which are beyond the Company’s control) and assumptions.

Although Generac believes any forward-looking statements are based on reasonable assumptions, you should be aware that many factors could affect Generac’s actual financial results and cause them to differ materially from those anticipated in any forward-looking statements, including:

  • frequency and duration of power outages impacting demand for our products;
  • fluctuations in cost and quality of raw materials required to manufacture our products;
  • availability of both labor and key components from our global supply chain, including single-sourced components, needed in producing our products;
  • the possibility that the expected synergies, efficiencies and cost savings of our acquisitions will not be realized, or will not be realized within the expected time period;
  • the risk that our acquisitions will not be integrated successfully;
  • the impact on our results of possible fluctuations in interest rates, foreign currency exchange rates, commodities, product mix, logistics costs and regulatory tariffs;
  • the duration and impact of the COVID-19 pandemic;
  • difficulties we may encounter as our business expands globally or into new markets;
  • our dependence on our distribution network;
  • our ability to invest in, develop or adapt to changing technologies and manufacturing techniques;
  • loss of our key management and employees;
  • increase in product and other liability claims or recalls;
  • failures or security breaches of our networks, information technology systems, or connected products;
  • changes in environmental, health and safety, or product compliance laws and regulations affecting our products, operations, or customer demand;

Should one or more of these risks or uncertainties materialize, Generac’s actual results may vary in material respects from those projected in any forward-looking statements. In the current environment, some of the above factors have materialized and may or will continue to be impacted by the COVID-19 pandemic, which may cause actual results to vary from these forward-looking statements. A detailed discussion of these and other factors that may affect future results is contained in Generac’s filings with the U.S. Securities and Exchange Commission (“SEC”), particularly in the Risk Factors section of the 2021 Annual Report on Form 10-K and in its periodic reports on Form 10-Q.
