Generac Holdings scores just 1/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.

Approach 1: Generac Holdings Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a company might be worth by projecting future cash flows and discounting them back to today using a required rate of return. It is essentially asking what all those future dollars are worth in today’s money.

For Generac Holdings, the latest twelve month Free Cash Flow stands at about $291.6 million. The 2 Stage Free Cash Flow to Equity model used here relies on analyst estimates for the next few years, then extends those projections further out. By 2030, projected Free Cash Flow is $910.1 million, with a full set of annual estimates and extrapolations out to 2035 provided by Simply Wall St.

Running these cash flows through the DCF model results in an estimated intrinsic value of about $244.61 per share, compared with the current share price of around $218. That implies the stock is about 10.7% undervalued based on this approach.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Generac Holdings is undervalued by 10.7%. Track this in your watchlist or portfolio, or discover 54 more high quality undervalued stocks.

Approach 2: Generac Holdings Price vs Earnings

For a profitable company, the P/E ratio is a useful way to think about what you are paying for each dollar of earnings. A higher P/E can reflect stronger growth expectations or lower perceived risk, while a lower P/E can point to more modest growth assumptions or higher risk.

Generac Holdings currently trades on a P/E of 80.31x. That sits above the Electrical industry average P/E of 34.07x and also above the peer group average of 45.15x. On the surface, this suggests the market is placing a richer price on Generac’s earnings than on many of its industry peers.

Simply Wall St’s Fair Ratio aims to refine that comparison. It estimates what a P/E might look like after adjusting for factors such as earnings growth, profit margins, industry, market cap and specific risks. Because it folds these elements into a single number, it can be more tailored than a simple peer or industry comparison.

For Generac Holdings, the Fair Ratio is 42.01x, which is materially lower than the current P/E of 80.31x. On this basis, the shares screen as expensive relative to what the Fair Ratio suggests.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Generac Holdings Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so meet Narratives, a simple way for you to write the story behind your numbers by linking what you believe about Generac’s future revenue, earnings and margins to a financial forecast, a fair value estimate and then comparing that fair value to today’s share price.

On Simply Wall St’s Community page, Narratives are an accessible tool used by millions of investors that stay current as new news, earnings and guidance are incorporated. This means your view on Generac can adjust as the facts change without you rebuilding a model from scratch.

For example, one Generac Narrative might lean toward the bearish fair value of about US$197 with assumptions closer to the more cautious analysts. Another could line up with the bullish fair value of about US$300 that reflects a stronger view on data center demand and margins. By comparing each Narrative’s fair value to the current market price you can decide whether the story you agree with points to the shares looking expensive, cheap or roughly in line with your expectations.

For Generac Holdings, we will make it really easy for you with previews of two leading Generac Holdings Narratives:

Start with the bullish case, which builds on stronger growth and margin assumptions. Then contrast it with the more cautious bear case to see which set of expectations feels closer to your view of how the business could develop.

Fair value in this bullish narrative: US$300.00 per share.

Implied discount to that fair value at the last close of US$218.38: about 27.2% undervalued.

Revenue growth assumption used: 15.47% per year.

• Assumes Generac’s data center and international businesses scale meaningfully, with capacity investments helping those segments play a much larger role in revenue and earnings by 2029.
• Builds in improving profitability, with margins rising as home standby generators, dealer network effects and higher margin connected services like ecobee and remote monitoring contribute more.
• Accepts material risks around regulation, cleaner technologies and competition, but concludes that the upside from data centers, outages and electrification can still support the higher fair value.

Fair value in this bearish narrative: US$197.00 per share.

Implied premium to that fair value at the last close of US$218.38: about 10.9% overvalued.

Revenue growth assumption used: 13.22% per year.

• Assumes that grid upgrades, renewables and storage gradually reduce the need for traditional generators, which pressures some of Generac’s most profitable product lines.
• Builds in lower future margins than the bullish view, reflecting competition, possible product obsolescence and ongoing regulatory and cost pressures in diesel and backup power.
• Recognizes data center and connected device opportunities, but treats them as not sufficient to offset the risks to core generator demand at the current share price.

The key takeaway is that both narratives use explicit assumptions for revenue growth, margins, valuation multiples and discount rates, but they reach very different conclusions about where fair value sits relative to today’s price. Your own stance on how far and how fast data centers, grid reliability, clean energy and regulation evolve will determine which of these stories feels closer to the version of Generac Holdings you want to anchor your expectations to.

Once you have that, you can use Narratives to fine tune the inputs, track updates over time and see how changes in the story affect the gap between your fair value and the market price.
