Baron Health Care Fund stated the following regarding Elanco Animal Health Incorporated (NYSE:ELAN) in its fourth quarter 2025 investor letter:
“We bought shares of Elanco Animal Health Incorporated (NYSE:ELAN), which sells medicines used to prevent and treat diseases in pets (cats and dogs) and farm animals (cattle, poultry, swine, and sheep). We believe Elanco operates in an attractive industry with secular growth drivers, including greater pet ownership, increased spending on pets, higher consumption of animal protein, and more focus on food safety. We believe Elanco is at an inflection point and is well positioned for consistent mid-single-digit revenue growth, margin expansion, and double-digit EBITDA and EPS growth. Elanco’s innovation portfolio is accelerating and becoming a larger percentage of the company’s revenue mix which will drive growth and gross margin expansion. Management guidance calls for $840 million to $880 million innovation revenue in 2025 (18.5% of total revenue) and $1.1 billion in 2026 (over 22% of estimated revenue), up from $461 million in 2024 (10.6% of total revenue). Key innovation products include, among others: Credelio Quattro, a monthly chewable tablet for dogs that protects against fleas, ticks, heartworms, roundworms, hookworms, and three different species of tapeworms; Zenrelia, a medicine for atopic dermatitis in dogs; Befrena, a monoclonal antibody targeting IL-31 for allergic dermatitis and atopic dermatitis, expected to launch in the first half of 2026; Bovaer, a methane-reducing feed ingredient for use in lactating dairy cattle; and Experior, a product used in cattle to reduce ammonia gas emissions. Further, the company’s innovation pipeline consists of five to six additional products expected to be approved 2026-2031 with potential unadjusted peak sales of $2 billion. The innovation portfolio generates above corporate average gross margins and should drive gross margin expansion as these products become a bigger percentage of the overall mix. Management is targeting 200-350 bps of EBITDA margin expansion from 2025-2028. Management is targeting $1 billion of cumulative free cash flow 2026-2028 which the company will use to pay down debt and lower net debt to EBITDA from 3.7 times to 3.8 times at the end of 2025 to 2.0 to2.5 times at the end of 2028. We think management’s targets could be conservative and we see long term upside in the stock.”
