Leszek Sulewski's questions to ANI PHARMACEUTICALS (ANIP) leadership

Question · Q2 2025

Les Sulewski asked for clarification on what drove the significant increase in Cortrophin's guidance since the last update and how ANI outpaced competitor growth. He also inquired about the new product cadence for generics, potential FDA approval delays, and Cortrophin's supply chain capacity.

Answer

President, Director & CEO Nikhil Lalwani attributed the raised guidance to several factors outperforming expectations, including the rapid impact of the sales force expansion, acceleration in new indications, and strong uptake of the prefilled syringe. He reiterated a focus on market growth over market share. Regarding generics, he noted strong R&D execution with no material FDA delays and an expected continued cadence of new launches.

Question · Q1 2025

Leszek Sulewski asked about the trend in naive patient adoption for Cortrophin, the target patient for the prefilled syringe, and its margin impact. He also inquired about the 2025 gross margin outlook, the size of the Medicare Part B patient subset for ILUVIEN, the risk if foundation funding does not return, and whether sales force turnover impacted Cortrophin.

Answer

President and CEO Nikhil Lalwani and CFO Stephen Carey responded. Lalwani noted the naive prescriber base continues to grow and the prefilled syringe is a convenience option with limited near-term margin impact. Carey reiterated the full-year gross margin guidance of 63-64%. Lalwani added that if foundation support for the impacted Medicare Part B patients does not return, ILUVIEN sales would likely trend toward the lower end of its guidance range. He also confirmed the sales force turnover tempered Cortrophin's potential growth but the new team will benefit both products.

Leszek Sulewski's questions to biote (BTMD) leadership

Question · Q2 2025

Les Sulewski of Truist Securities asked about the primary drivers of the higher-than-expected clinic attrition, questioning if the adoption of GLP-1s was a contributing factor or if the causes were more internal. He also requested details on the company's longer-term initiatives.

Answer

CEO Bret Christensen responded that the company views GLP-1s as complementary, not a cause of attrition. He attributed the procedure revenue headwinds to two main internal disruptions: the launch of the CDSS software in Q3 2024, which distracted the sales team, and the subsequent organizational restructuring in May 2025. Christensen emphasized that while these actions were necessary for long-term growth, they created short-term slowdowns and the company is still feeling their effects.
