How Do These Events Affect Cisco Systems, Inc.'s Financial History?
Acquisitions and disposals break the comparison from one year to the next. Growth in fiscal 2024 and the year after mixes the existing business with what was bought or sold, so the 10-K's discussion of results, which usually separates the two, says more than the headline growth rate in those years.
Each year shows the revenue from the latest 10-K that reported it, so a year a company later restated can differ from the figure it first published, and most companies moved to a new revenue tag after the 2018 change in revenue accounting.
