Pipeline & Strategic Developments

• ARO-PNPLA3 siRNA Asset:
  • Licensed from Arrowhead Pharmaceuticals for global rights. Targets patients homozygous for PNPLA3 mutation, which is highly prevalent among Hispanic populations and represents about 30% of MASH patients with moderate to advanced fibrosis (F2/F3).
  • Phase 1 trial data show up to 46% reduction in liver fat (MRI-PDFF) at 12 weeks post-single high dose in PNPLA3 I148M homozygous patients.
• Expansion with Six Preclinical siRNA Programs:
  • Acquired global rights in February 2026, targeting genetically validated drivers of MASH. Preclinical development ongoing.
  • Strategy aims for combination therapies leveraging Rezdiffra’s efficacy and genetically targeted approaches.
• Upcoming Clinical Milestones:
  • MGL-2086 (oral GLP-1) Phase 1 trial set for Q2 2026.
  • Ervogastat/resmetirom drug-drug interaction study to start in Q4 2026.
• Intellectual Property: Patent protection for Rezdiffra expected to last until 2045, supporting long-term leadership in MASH therapies.

Scientific & Market Leadership

• Only FDA and European Commission approved liver-directed therapy for MASH with moderate to advanced fibrosis.
• Ongoing Phase 3 trial for Rezdiffra in compensated MASH cirrhosis (F4c).
• Real-world efficacy data and cardiovascular risk reduction: Secondary analysis from MAESTRO-NASH/NAFLD1 shows Rezdiffra lowers Lp(a) and LDL-C, supporting its potential to reduce cardiovascular risk independently of statin use.

Risks and Considerations for Shareholders

• Net loss widened significantly due to investment in pipeline expansion and commercial activities.
• High investment in R&D and SG&A may continue as the company pursues strategic growth and new product launches.
• Cash position remains strong, but declined from year-end 2025, reflecting aggressive investment in pipeline and commercial expansion.
• Potentially price-sensitive news:
  • Blockbuster sales performance for Rezdiffra, rapid patient adoption, and market expansion could drive share value higher.
  • Strategic pipeline additions, especially the clinical-stage siRNA asset targeting PNPLA3, open new patient segments and strengthen Madrigal’s competitive position.
  • One-time business development expenses may impact short-term earnings but are likely to be viewed as investments for long-term growth.
  • Patent protection until 2045 provides extended exclusivity, potentially boosting investor confidence.
• Forward-looking statements are subject to risks including regulatory approvals, commercial success, clinical trial outcomes, and competitive trends.

Upcoming Shareholder Events

• Madrigal will host a webcast and conference call to review financial and business updates. Archived webcast will be available on the company website.
• Significant scientific presentations at the EASL Congress (May 27-30, 2026) may further bolster market confidence.

Conclusion

Madrigal Pharmaceuticals delivered exceptional revenue growth and patient expansion for Rezdiffra in Q1 2026, solidifying its leadership in the rapidly growing MASH market. Strategic pipeline additions, especially the siRNA assets, and continued investment in commercialization and R&D are notable for long-term value creation. While net losses widened due to aggressive investment, the strong cash position and patent protection until 2045 strengthen the company’s outlook. With favorable market dynamics and multiple clinical milestones ahead, these developments are highly relevant for shareholders and may materially impact share price.
