In September, CSL applied to ASX for quotation of 834,408 additional ordinary shares.

Key Catalysts to Watch

• Continuation of plasma collections growth supporting CSL Behring's Revenue outlook

• Pipeline updates from the Garadacimab (HAEGARDA) and CSL112 programs

• Integration progress and synergy realisation from the Vifor Pharma acquisition

• Any revisions to FY2027 Earnings guidance from management

Risks

• Currency headwinds as the majority of revenue is earned in USD and EUR

• Competition in the immunoglobulin market from global biosimilar entrants

• Regulatory delays affecting pipeline candidates

• Ongoing cost pressure from plasma collection operations

Conclusion

CSL remains one of the highest-quality businesses listed on the ASX, with a diversified global portfolio and a track record of consistent earnings growth.
