How this year-over-year comparison is scoped
The comparison uses consecutive CMS program years only (current = prior + 1) from the manufacturer General Payments summary and excludes research and ownership or investment records. Non-consecutive year pairs are not shown as year-over-year change. This General Payments figure is not the all-tracks company total in the hero.
CMS source labels for this exact identifier: PY2022: EISAI INC.PY2023: EISAI INC.PY2024: Eisai Inc.. Matching identifiers support a bounded record comparison; a label difference would be reported as unresolved rather than treated as a corporate event.
