CSL resets around plasma as Vifor shrinks
CSL is a steady plasma business recovering from a costly reset, with $7.1 billion of FY26 impairments and a modest FY27 outlook. The plasma side looks stable, but growth depends on cutting collection costs and replacing Vifor's lost sales under a new chief executive.

5/10 Neutral view
The plasma business still generates cash, but a $2.6 billion loss, a guidance cut, shrinking Vifor and a pipeline the chair says did not deliver weigh heavily.

Opinion only. The Investor Rank is aibio.space's opinion of the company's business position, drawn from the public sources on this page. It is not a recommendation to buy, sell or hold any security and it is not investment advice. It does not consider the share price, valuation or your circumstances, and it can change at any time. Payments from companies never affect it. How the rank works.
- Technology
- Mature plasma platform. Immunoglobulin, albumin and clotting factors drive most sales, with newer drugs Hemgenix and Andembry growing from a small base.
- Odds
- Thin pipeline. The chair said CSL's R&D did not deliver, and the newest program, lixudebart, is in phase 2.
- Balance sheet
- Solid cash generation. Operating cash flow was $3.5 billion in FY26 and leverage 1.8 times, enough to fund the dividend and an A$1.1 billion buyback.
- Main risk
- Shrinking Vifor and policy pressure. Vifor revenue is guided down about 25% in FY27, and U.S. pricing agreements cap future launch prices.
- Watch next
- Leadership and margins. The Oct. 27 AGM, Deborah Waterhouse's start on Feb. 1, 2027 and progress on plasma collection costs.
