Is DAR a Buy? What to Consider in 2026
Last updated June 2026
Short answer
There is no universal answer to whether DAR is a buy; it depends on your thesis, time horizon, and what you already own. Below is the case for Darling Ingredients, the main risks to weigh, where the stock trades, and a framework to decide for yourself. This is informational, not a recommendation, and Walnut is not an investment adviser.
Darling Ingredients is the world's largest publicly traded processor of animal byproducts and food waste, turning materials that would otherwise be discarded into useful ingredients and renewable energy. The company collects used cooking oil, animal fat, bone, blood, feathers, and other byproducts from meat processors, restaurants, and grocers, then renders and refines them into proteins, fats, gelatin, fertilizers, and feedstocks. Its Feed segment produces animal feed ingredients and pet-food proteins, while the Food segment, led by the Rousselot business, is a leading maker of gelatin and collagen used in pharmaceuticals, food, and health products. Darling's most prominent growth driver is Diamond Green Diesel, a renewable-diesel and sustainable-aviation-fuel joint venture with Valero that converts low-carbon fats and oils into clean transportation fuel. The company earns revenue from selling these ingredients globally and from renewable fuel volumes plus associated low-carbon credits. Darling is headquartered in Irving, Texas, and operates rendering and processing plants across the Americas, Europe, and Asia.
The case for Darling Ingredients
1. Renewable diesel and SAF.
The Diamond Green Diesel joint venture with Valero is the centerpiece growth story, converting waste fats and oils into renewable diesel and sustainable aviation fuel. As low-carbon fuel mandates and SAF demand expand, Darling's secure access to low-carbon feedstock through its global rendering network gives it a structural advantage that integrated fuel producers struggle to replicate.
2. Vertically integrated feedstock supply.
Darling's core rendering and used-cooking-oil collection network is the moat. By controlling the supply of fats and oils, it feeds its own renewable-fuel ambitions and sells surplus to others. This vertical integration protects margins when feedstock prices spike and gives the company a low-cost, hard-to-replicate position in the low-carbon-intensity feedstock chain.
3. Specialty ingredients and collagen.
The Food segment, anchored by Rousselot gelatin and collagen, serves growing pharmaceutical, nutrition, and health markets, including collagen peptides for the wellness trend. These specialty ingredients carry higher and more stable margins than commodity rendering, diversifying Darling away from volatile fuel and feed prices.
4. Circular-economy positioning.
Darling sits at the center of a circular economy, upcycling waste streams into food, feed, fertilizer, and fuel. As sustainability mandates tighten and customers seek low-carbon inputs, the company benefits from regulatory tailwinds and from being an essential outlet for byproducts the meat and food industries must dispose of.
The risks to weigh
Darling's earnings are highly exposed to volatile commodity and fuel prices, including fats, oils, soybean oil, and renewable-fuel margins. Renewable diesel economics depend heavily on government policy: blenders tax credits, the shift to producer credits, low-carbon fuel standards, and the Renewable Fuel Standard, all of which can change and compress margins. The Diamond Green Diesel venture concentrates a large share of profit in a single program. Feedstock costs can rise, SAF ramp may disappoint, and global rendering is a low-margin, capital-intensive business. The stock has been cyclical and sensitive to policy headlines and fuel-spread swings.
Valuation context (as of early 2026)
- Revenue (TTM): ~$6 billion
- Operating margin: Mid-single-digit to low-double-digit, cyclical
- EBITDA: ~$1 billion, varies with fuel margins
- Revenue growth: Cyclical, swings with commodity and fuel prices
- P/E (TTM): Moderate, volatile with earnings cycle
- Dividend yield: None (no dividend; reinvests in growth)
- Free cash flow: Variable, pressured by growth capex
- Balance sheet: Leveraged from renewable-fuel investment
Darling's valuation is cyclical and heavily tied to renewable-diesel and feedstock spreads, so reported multiples swing with the fuel-margin cycle. The market often values it on EBITDA and on the long-term earnings power of Diamond Green Diesel rather than trailing earnings. Policy shifts and fuel-spread volatility make the financial profile lumpier than a typical consumer-staples ingredient company.
How to decide for yourself
Rather than asking whether DAR is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold DAR indirectly through an index or sector ETF before adding more.
