How have CSL Ltd's (CSL) revenue, margins and earnings per share trended over the past decade?
CSL Ltd's revenue has grown from $6.1B in FY2016 to $15.4B in FY2025, a roughly 2.5-times increase, with the largest single-year gains recorded in FY2023, when revenue rose to $13.2B from $10.5B, and again in FY2025, when it advanced to $15.4B from $14.7B in FY2024.
Margins have moved within a fairly contained but declining range over time. Gross margin rose from 48.0% in FY2016 to a peak of 56.1% in FY2021, before settling at 51.5% in FY2025. Operating margin followed a similar rise-then-fade pattern, peaking at 28.9% in FY2019 and finishing at 19.2% in FY2025, while net margin peaked around 23.1% in FY2020-FY2021 and ended FY2025 at 19.5%, after a low of 16.7% in FY2023.
Diluted earnings per share rose from $2.68 in FY2016 to $6.18 in FY2025 but did not climb in a straight line — it reached $5.24 in FY2021, slipped to $4.80 in FY2022, jumped to $6.89 in FY2023 even as the diluted share count grew only modestly to 482.2 million, then fell back to $5.45 in FY2024 before recovering to $6.18 in FY2025.
