Why is Alvotech stock climbing today?
Alvotech (ALVO) stock rose 7% in pre-market trading after FDA approved its new manufacturing process for SIMLANDI, a biosimilar to Humira. The approval allows the company to double drug substance output per batch, freeing up capacity for other products. This follows another FDA approval in October. The S&P 500 and NASDAQ were down slightly, indicating the move was driven by company-specific news. Analysts have a 'Moderate Buy' consensus with an average price target above current levels.
