Here are 3-5 expected drivers of future revenue growth for Darling Ingredients (DAR) over the next 2-3 years:

1. Resilience and Growth in Core Ingredients Business: Darling Ingredients' CEO consistently emphasizes the strength and resilience of its diversified core ingredients business, particularly within the Feed and Food segments. This segment is supported by sustained global demand, with strong performance noted in Q3 2025. The company expects its Feed segment to remain consistent or slightly improve, and its Food segment is anticipated to rebound as global collagen demand strengthens.
2. Expansion into High-Growth Specialty Food Ingredients: The company is strategically expanding its presence in high-growth, high-margin specialty ingredients. The Nextida joint venture, which combines Darling Ingredients' and Tessenderlo Group's collagen and gelatin segments, is specifically expected to broaden Darling's product portfolio with items like collagen and functional peptides, driving Food segment EBITDA growth starting in 2026.
3. Growing Demand for Sustainable Aviation Fuel (SAF): Despite facing regulatory headwinds in the broader renewable fuels sector, the ongoing demand for Sustainable Aviation Fuel (SAF) is a significant future growth driver. Darling Ingredients started up one of the world's largest SAF units in Port Arthur, Texas, in Q4 2024, and a positive renewable fuels policy outlook is expected to support future growth in this area.
4. Monetization of Production Tax Credits (PTCs): While not direct revenue, the monetization of Production Tax Credits (PTCs) is expected to significantly bolster Darling Ingredients' financial position. The company anticipates selling an additional $125-175 million in PTCs by the end of 2025, with a robust market and strong buyer demand. This enhances profitability and can support further investments in growth initiatives.
5. Strategic Acquisitions and Operational Efficiency: Darling Ingredients has a history of integrating acquisitions globally to position itself for future growth and adapt to market dynamics. Furthermore, the company maintains a strong focus on optimizing operational efficiency and cost management across its segments, which contributes to margin improvement and overall financial health, indirectly supporting revenue growth by enhancing competitiveness and profitability.
