Animal health company Zoetis reported second-quarter fiscal year 2026 revenue of $2.5 billion, flat compared to the same period last year, with organic operational revenue decreasing by 1%. The company lowered its full-year revenue forecast from $9.68-$9.96 billion to $9.12-$9.32 billion, and now expects organic operational revenue to decline by 1%-3%, a reversal from its previous expectation of 2%-5% growth. Adjusted diluted earnings per share (EPS) guidance was also reduced from $6.85-$7.00 to $6.15-$6.25. The pressure on performance is primarily due to weak demand in the U.S. companion animal market, though growth in livestock and international markets provided resilience.
