• Simply Wall St currently gives Green Plains a 5 out of 6 valuation score. The sections ahead will compare different valuation methods, followed by a more complete way to think about what the stock might be worth.

Approach 1: Green Plains Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a company could be worth by projecting its future cash flows and discounting them back to today. It links the share price to the cash the business is expected to generate over time.

For Green Plains, the model used is a 2 Stage Free Cash Flow to Equity approach, based on cash flow projections in $. The latest twelve month free cash flow is about $46.8 million. Analyst estimates feed into forecasts such as $144.4 million of free cash flow in 2026 and $225.2 million in 2027, and Simply Wall St extends these out to around $610.1 million in 2035 using its own assumptions.

When all those projected cash flows are discounted back and combined with a terminal value, the DCF model suggests an intrinsic value of about $167.56 per share. Compared with the recent share price of $15.41, this indicates that, within this framework, the stock appears 90.8% undervalued.

Result: UNDERVALUED (within this DCF framework)

Our Discounted Cash Flow (DCF) analysis suggests Green Plains is undervalued by 90.8%. Track this in your watchlist or portfolio, or discover 60 more high quality undervalued stocks.

Approach 2: Green Plains Price vs Sales

For companies where current earnings are not a clean guide, price based on sales can be a useful cross check because revenue is often more stable than profit. The multiple investors are willing to pay for each dollar of sales usually reflects what they expect for growth and how much risk they are taking on, so a higher P/S ratio is often linked to higher growth expectations or lower perceived risk, and vice versa.

Green Plains currently trades on a P/S ratio of 0.51x. That compares with an Oil and Gas industry average P/S of 1.99x and a peer group average of 0.72x, so the stock is trading below both of those benchmarks.

Simply Wall St also calculates a Fair Ratio of 0.62x for Green Plains. This is a proprietary estimate of what the P/S ratio might be given factors such as the company’s growth profile, profit margins, size, industry and specific risks. That makes it a more tailored yardstick than a simple comparison to peers or the broad industry, which may not share the same mix of risks and business characteristics.

Set against the current 0.51x P/S, the 0.62x Fair Ratio points to Green Plains looking undervalued on this measure.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Green Plains Narrative

Earlier it was mentioned that there is an even better way to understand valuation. Narratives bring this to life by letting you attach a clear story about Green Plains to the numbers you think are reasonable for future revenue, earnings, margins and a fair value estimate.

A Narrative connects three pieces in one place: the company story, a forward looking financial forecast and the fair value that results from those assumptions. This helps you see how a view about policy risk, execution or demand translates into a concrete number.

On Simply Wall St, Narratives sit in the Community page and are used by many investors as a tool to compare their own fair value to the current share price and consider whether Green Plains appears more like a potential opportunity or a potential risk.

Because Narratives update when new information comes in, such as earnings results or policy news affecting clean fuel credits, your fair value view can adjust without needing to rebuild every model from scratch.

For Green Plains today, one Narrative anchors on a fair value of US$10 and another on US$19. This highlights how different investors can look at the same business, use different assumptions about growth, margins and P/E multiples, and arrive at very different conclusions about what the shares are worth.

For Green Plains however we will make it really easy for you with previews of two leading Green Plains Narratives:

Fair value in this bullish Narrative: US$19.00 per share.

At the last close of US$15.41, this view implies the shares are about 18.9% below that fair value.

Revenue growth assumption in this Narrative: 20.8% a year.

• Focuses on expanding premium low carbon production, higher margin coproducts and process improvements that could lift earnings power.
• Assumes cost reductions and an efficiency focused culture support stronger margins and potentially higher EBITDA multiples.

At the last close of US$15.41, this view implies the shares are about 54.1% above that fair value.

Revenue growth assumption in this Narrative: 21.0% a year.

• Points to volatile commodity markets, heavy capital spending and execution risk on large projects as sources of earnings and cash flow uncertainty.
