Industry Context

The biopharmaceutical industry is highly capital-intensive, with significant funding required for research, development, clinical trials, and commercialization of new therapies. Public offerings like Insmed's are a common mechanism for companies in this sector to raise substantial capital to advance their pipelines and bring new treatments to market, especially for serious diseases with high unmet needs. This offering positions Insmed to continue investing in its diverse portfolio of approved and investigational medicines, aligning with the industry's focus on innovation and expansion.

Comparison to Industry Standards

• Capital raises of this magnitude are typical for biopharmaceutical companies with late-stage clinical assets and commercial products, as R&D and market launch costs are substantial.
• The granting of a 30-day option to underwriters for additional shares is a standard practice in underwritten public offerings, allowing for price stabilization and additional capital if demand is strong.
• The stated use of proceeds for R&D, pre-commercial, and commercialization activities is consistent with how biopharma companies typically deploy capital raised through equity offerings, focusing on pipeline progression and market penetration for key products like ARIKAYCE and brensocatib.

Stakeholder Impact

• Shareholders: Experience dilution due to the issuance of new common stock, potentially impacting earnings per share and ownership percentage.
• Company: Strengthened financial position to fund critical research and development, accelerate commercialization efforts, and pursue business expansion activities.
• Employees: Continued investment in R&D and commercialization may lead to job stability and potential growth opportunities within the company.
• Customers/Patients: Increased funding for drug development could lead to new or improved therapies becoming available, particularly for serious diseases.

Next Steps

• Consummation of the sale and purchase of the Firm Shares pursuant to the Underwriting Agreement on June 13, 2025, subject to customary closing conditions.
• Potential exercise of the underwriters' 30-day option to purchase up to an additional 1,171,875 shares of common stock.
• Continued research and development of brensocatib, treprostinil palmitil inhalation powder (TPIP), INS1201, and other pre-clinical product candidates.
• Pre-commercial and commercialization activities related to brensocatib, if approved.
• Further commercialization and development of ARIKAYCE.
• Listing of the newly issued Securities on the Nasdaq Global Select Market.
