DAR vs VLO: How Darling Ingredients and Valero Energy Compare (2026)

Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. DAR and VLO share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined DAR and VLO exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

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.

Valero Energy is the largest independent petroleum refiner in the world, operating 15 refineries across the United States, Canada, and the United Kingdom with a combined throughput capacity of roughly 3.2 million barrels per day. Unlike an integrated major, Valero does not produce much of its own crude oil, so it makes money on the spread between the cost of crude and the price of refined products like gasoline, diesel, and jet fuel (the refining margin, or crack spread). It reports three segments: Refining, which is the core profit engine; Renewable Diesel, run through the Diamond Green Diesel joint venture with Darling Ingredients; and Ethanol, from a network of corn ethanol plants.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• DAR drivers: Renewable diesel and SAF; Vertically integrated feedstock supply.
• VLO drivers: Scale in refining and record throughput; Heavy capital returns to shareholders.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Darling's earnings are highly exposed to volatile commodity and fuel prices, including fats, oils, soybean oil, and renewable-fuel margins. For VLO, valero's earnings are highly cyclical and depend on refining crack spreads, which can collapse quickly when product demand weakens or new refining capacity comes online, as shown by the net loss it reported in the first quarter of 2025.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick DAR if you believe its drivers more; VLO if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the DAR and VLO guides.

DAR. 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.

VLO. Valero swung from a Q1 2025 net loss to about $1.3 billion of net income in Q1 2026 as refining margins recovered, and full-year 2025 net income was roughly $2.3 billion (about $3.3 billion adjusted). At a share price near $290 and a market cap around $86 billion, the stock trades near 20 times trailing earnings, though refiner multiples are noisy because earnings gyrate with the margin cycle.

Headline figures (approximate, early 2026): DAR shows 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; VLO shows revenue (ttm) ~$130 billion, net income (fy2025) ~$2.3 billion ($7.57 EPS), adjusted eps (fy2025) ~$10.61, q1 2026 net income ~$1.3 billion ($4.22 EPS).

DAR and VLO are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
