Zero-Coupon CB Wave Reshapes Korean Biotech Financing

The Korean biotech sector is experiencing a surge in zero-interest convertible bond issuances, with investors choosing to forgo coupon income entirely in exchange for exposure to clinical-stage upside. According to Seoul Economic Daily, this "issuer-led market" is particularly favoring companies with high-momentum pipelines and credible licensing-out track records.
D&D Pharmatech's 226.5 billion won CB issuance stands out as the largest single biotech financing deal in Korea this year. The deal reflects growing investor confidence in the company's clinical assets and its potential to execute global out-licensing agreements. Across the broader market, combined zero-interest CB issuances over the past six months have reached 1.1 trillion won, underscoring how entrenched this fundraising model has become.

Genomics-focused startup Threebillion is also participating in this financing wave. The company, known for rare disease diagnostics using AI-assisted genomic sequencing, is reportedly tapping CB markets as it advances its clinical programs.
GLP-1 Boom Disrupts Korean Clinic Economics
Separately, a report published within the past 48 hours by NewsSpace highlights how the meteoric rise of GLP-1 receptor agonist drugs — including Novo Nordisk's Wegovy and Eli Lilly's Mounjaro — is directly affecting the profitability of clinics in Korea that specialize in related metabolic and weight-management treatments. The GLP-1 market's explosive growth is forcing domestic healthcare providers to adapt their business models in response to rapidly shifting patient demand.
