Protagonist Therapeutics posts Q3 earnings beat and launches $300 M share repurchase

Protagonist Therapeutics reported third‑quarter GAAP earnings of $3.07 per share on revenue of about $274 million, both above analyst forecasts. Net income was $220 million. The company also announced FDA approval of its MIMRYLO product and authorized a $300 million share‑repurchase program. Shares slipped 1.8% in after‑hours trading.

The earnings beat may support the new $300 million repurchase plan, which could provide price support for the stock. However, the modest after‑hours price decline signals that investors are weighing the results against expectations.
