Why is the CSL share price in the red?
There is no price-sensitive news out of CSL this morning, so it's safe to say the stock is falling simply because it's gone ex-dividend.
It's normal for an ASX share to fall on its ex-dividend date because it's no longer trading with the next dividend entitlement attached.
With the official earnings season now over, CSL is one of more than 35 ASX shares going ex-dividend this week.
Here's what CSL will pay.
What is the CSL dividend?
CSL shares will pay a final unfranked dividend of US$1.62, or about AU$2.46 per share, on 3 October.
The CSL share price was smashed after the company released its FY25 report on 19 August.
The stock fell almost 20% to a six-year low within two days.
The CSL share price was among the biggest fallers post-results during earnings season.
CSL reported a 5% revenue rise to US$15.6 billion and a 17% increase in net profit after tax (NPAT) to US$3 billion for FY25.
Investors were rattled by CSL management's wide-ranging strategy to restructure the business.
This included the surprise demerger of the Seqirus vaccines division. It will be listed as a separate entity on the ASX in FY26.
Some investors have lost faith in CSL as it deals with multiple headwinds, particularly in terms of research and development (R&D).
The failure of the CSL112 heart drug during trials, falling vaccine rates post-COVID, weakness in the Behring blood plasma business, and lacklustre results from Vifor, the nephrology business acquired for US$11.7 billion in 2021, have all had an impact.

The buyback began last Thursday.
According to yesterday's buyback update, CSL has already repurchased almost 400,000 shares.
