What are the key drivers and restraints affecting its financial trajectory?

Drivers:

  • Increasing demand for oral contraceptives driven by global population growth.
  • Rising awareness and acceptance of hormonal methods.
  • Prescription data showing steady increases in contraceptive use among reproductive-age women.
  • Expanding insurance coverage in developed markets.

Restraints:

  • Patent expiry approaching in 2028.

The initial growth phase is driven by increased adoption in North America and Europe, followed by penetration in Asian markets. Post-2028, revenue is expected to decline due to generic competition unless new indications or formulations are introduced.
