Puma Biotechnology (NASDAQ: PBYI) was added to the Nasdaq Biotechnology Index (NBI) at the close of trading on December 19, 2025, following a formal announcement on December 23, 2025. The NBI tracks the performance of biotechnology and pharmaceutical companies listed on Nasdaq and requires a minimum market capitalization of $200 million, an average daily trading volume of 100,000 shares, and at least one year of public trading. Puma’s inclusion confirms that it has met these thresholds and positions the company alongside peers such as Amgen and Biogen.
The move is a strategic milestone that expands Puma’s exposure to institutional investors and index‑tracking funds. By being part of the NBI, the company gains automatic inclusion in portfolio rebalancing strategies that follow the index, potentially increasing demand for its shares and improving liquidity. Management highlighted that the inclusion reflects sustained commercial execution, profitability, and clinical progress, underscoring the company’s growth trajectory.
Financially, Puma reported a net income of $8.8 million in Q3 2025, down from $20.3 million in Q3 2024, but the company’s cash position remained robust at $94.4 million as of September 30, 2025. Revenue from the flagship product NERLYNX rose 10.5% year‑over‑year to $49.2 million in Q2 2025, driven by strong demand in the extended adjuvant HER2‑positive breast cancer market. The company’s investigational drug alisertib continues to advance, with Phase II trials in small cell lung cancer and breast cancer progressing under FDA orphan drug designation. These clinical developments reinforce the company’s pipeline strength and support the market’s confidence reflected in the index inclusion.
Management emphasized that the NBI addition is “an important recognition of Puma’s continued commercial execution, profitability, and clinical progress.” The company’s CEO, Alan H. Auerbach, noted that sustained demand for NERLYNX and the advancing alisertib program are key drivers of the milestone, and that the inclusion will help broaden the investor base and support future growth initiatives.
While specific market reaction data is not available, the inclusion is expected to be viewed positively by investors who track the NBI, as it signals that Puma meets the rigorous criteria for market capitalization, liquidity, and public trading history. The event also aligns with the company’s broader strategy of expanding its commercial footprint and advancing its pipeline, positioning Puma for continued growth in the biotechnology sector.
