- Generic Approval: Health Canada approved the first generic versions of Ozempic from Dr. Reddy's Laboratories on April 28, followed by another from Apotex, marking the beginning of increased market competition.
- Market Impact Assessment: Analyst Evan Seigerman noted that these new generics could lead to a decline in international revenue for semaglutide, although the impact on the U.S. market is expected to be limited due to competition from Eli Lilly's Mounjaro.
- Novo's Response Strategy: Emil Kongshøj Larsen, EVP of International Operations at Novo Nordisk, stated that the impact of generics is anticipated to be in the low single digits, highlighting the strong uptake of their savings card strategy in Canada.
- Pricing Policy Change: Canadian policy mandates a 65% price cut to Novo's list price once three generic competitors enter the market, which will significantly influence their future market strategy.

- International Market Expansion: Mounjaro generated $4.2 billion in U.S. sales, up 59%, while international sales skyrocketed from $1.2 billion to $4.4 billion, primarily due to its inclusion in China's National Reimbursement Drug List, indicating strong global growth potential.
