Diamond Green Diesel becoming profitable and generating US$107.4 million in equity income in Q1 2026 gave Darling Ingredients a very different earnings profile compared with the year before. Holding Darling Ingredients from the start of the year would have returned 48.8%, including dividends. If you had put fresh money into the shares on 1 January 2026, what exactly did you need to believe about fat prices, policy support, and upcycled waste demand before that turnaround hit the headlines?
If the move has made Darling Ingredients harder to judge, start where the gap is still open and scan 32 high quality undervalued stocks.
The shares cost US$36 at the start of the period, and anyone buying Darling Ingredients then was really choosing between two very different stories.
The bullish narrative pointed to a Fair Value of US$60, a price level justified by its own assumptions, built on confidence that decarbonization policy and demand for domestic fats would support higher feedstock pricing and stronger earnings power.
The bearish view put Fair Value at US$34, again purely as the price its thesis implied, and focused on regulatory uncertainty around RINs and small refinery exemptions as a risk that could keep renewable fuel margins under pressure.
Diamond Green Diesel turning profitable and delivering US$107.4 million of equity income in Q1 2026 backed the bullish Darling Ingredients story on policy support, fat pricing, and renewable fuel demand. Q3 2026 results added weight, with revenue rising from US$1,563.97 million to US$1,791.12 million and net income climbing from US$19.36 million to US$266.99 million. The net margin shift from 1.2% to 14.9% strongly supported the optimistic case.
The key lesson travels well. When a thesis hinges on better margins from policy and product mix, focus on reported net margin and segment EBITDA, not just headline revenue. For another ingredients or biofuel group, test whether higher feedstock prices and regulatory support are actually showing up as sustained profitability, not just one strong quarter.
Darling Ingredients now trades at US$55.99, after a 48.8% total return from the start of the year. The analyst consensus Narrative on Simply Wall St sees Fair Value above that level, built on policy support, mix improvement and cash generation rather than a single volume story.
For anyone paying today’s price, the key question is whether renewable diesel and SAF margins, collagen economics and efficiency gains can keep supporting the earnings power that Narrative assumes. The supported business assumption that would have to hold is that these margin drivers stay intact rather than being eroded by policy or commodity shifts.
"The current valuation implies that the market already prices in continued strong margins, delivery of the targeted $4 to $6 billion of free cash flow in 2026 to 2030 and meaningful capital returns, which together would need to justify a bullish view that Darling Ingredients is undervalued."

After watching Darling Ingredients lean into waste, you might ask what balances that exposure. One possible answer already sits in your kitchen cupboard.
Packaged food giants often depend on steady cash generation and entrenched brands. That approach can feel dull compared with renewable diesel excitement.
Yet brand owners investing in marketing, product quality and efficiency address a different challenge. They work to keep everyday staples relevant without pulling their businesses apart.
When a mature food group protects its payout and reinvests in operations, it fills a different role beside Darling Ingredients. That contrast can subtly change how you think about resilience.
That argument has a Narrative and a number behind it. → See the company one Narrative values 39% above its price
