Amphastar Pharmaceuticals' third quarter results for 2025 came in ahead of Wall Street's revenue and profit expectations, despite essentially flat sales compared to the prior year. The quarter was shaped by strong performances from proprietary products BAQSIMI and Primatene MIST, both of which saw double-digit sales growth. Management attributed this momentum to enhanced commercial execution and expanded marketing partnerships. At the same time, the company faced pronounced margin pressure, primarily due to a sales mix shift, pricing declines, and increased competition in legacy products. CFO William Peters pointed to higher operating costs and a litigation provision that weighed on profitability, noting, “cost control measures were implemented to mitigate the impact of pricing pressures.”

While we enjoy listening to the management's commentary, our favorite part of earnings calls are the analyst questions. Those are unscripted and can often highlight topics that management teams would rather avoid or topics where the answer is complicated. Here is what has caught our attention.
