These companies operate in different sectors (PAHC (Healthcare) and NEOG (Healthcare) and IDXX (Healthcare) and TSN (Consumer Defensive) and ZTS (Healthcare)), which means they face different economic cycles, regulatory environments, and macro sensitivities — making direct comparison nuanced.

PAHC, TSN, ZTS pay a dividend while NEOG, IDXX do not, making them suitable for different income and tax situations.
