Strategic Priorities

Technology & Innovation Investment:

Intellectual Property Management: In April 2025, GSK and Pfizer finalized a global settlement concerning RSV patents, securing a royalty stream for GSK on sales of Abrysvo, demonstrating effective IP strategy execution.

6. Market Position & Outlook

GSK is well-positioned to capitalize on demographic trends driving healthcare demand, with a strong portfolio addressing aging populations, infectious disease prevention, and cancer treatment. The company's first-mover advantage in RSV vaccines and robust oncology pipeline provide multiple growth drivers.

GSK Financial Outlook & Targets
Metric 2024 Actual 2025 Guidance 2026+ Targets
Turnover Growth 3.46% 3-5% Sustained mid-single digit
Core Operating Profit Growth - 6-8% Double-digit CAGR to 2026
New Product Sales ~£3B Growing >£12B by 2026
Total Sales Target £31.4B £32B+ >£40B by 2031

Key Growth Drivers:

  1. Arexvy Market Expansion: Continued rollout in international markets and potential expansion to younger age groups
  2. Oncology Portfolio Growth: Blenrep expansion into earlier lines of therapy and new combination regimens
  3. Respiratory Franchise: Nucala COPD approval and depemokimab launch
  4. Pipeline Execution: 14 multi-blockbuster candidates advancing toward market
  5. Emerging Markets: Geographic expansion in high-growth regions

Risk Factors: Key risks include regulatory delays, competition from other RSV vaccines (Abrysvo, mResvia), pricing pressure in key markets, and potential pipeline setbacks. The company also faces ongoing litigation exposure, including the Zantac cases that impacted 2024 results.

Investment Thesis: GSK offers a compelling combination of established vaccine leadership, innovative pipeline assets, and strong financial returns. The company's focus on specialty medicines and vaccines positions it well for sustainable growth, while its commitment to R&D ensures continued innovation. The successful launch of Arexvy validates GSK's ability to deliver breakthrough medicines addressing significant unmet medical needs.
