Positive Impact 4 of 5 earnings Written later

Protagonist Therapeutics reported net income of $162.8 million for the quarter ended June 30, 2026, compared with a net loss of $34.8 million a year earlier. Most of the quarter's $213.5 million in license and collaboration revenue came from $192.4 million recognized from the Takeda opt-out payment, so the result reflects a large one-time-style accounting benefit rather than the ongoing run rate. The company also said it expects research and development expense to rise significantly in the second half of 2026.
