Yuan Zhi's questions to RadNet (RDNT) leadership

Question · Q3 2025

Yuan Zhi asked for clarification on the digital health revenue outlook for Q4 after the iCAD acquisition, specifically if it would be flat or decreasing year-over-year, and requested comments on PET/CT volume growth from oncology versus Alzheimer's, including preparations for new agent launches in 2026.

Answer

Mark Stolper, EVP and CFO, clarified that RadNet did not imply a decrease in digital health revenue, having increased guidance by $5 million, with iCAD contributing $3.9 million in Q3, and expects strong Q4 performance. He explained that PET/CT growth is significantly driven by PSMA prostate imaging (12% of volume) and amyloid brain studies (8% of volume), both underutilized. He also noted that several novel radioactive tracers in final clinical trials are expected to further boost nuclear medicine and PET/CT utilization in the coming years.

Question · Q2 2025

Yuan Zhi from B. Riley Securities inquired about the supply-demand dynamics and pricing sensitivity in the nuclear medicine market, and asked for the conventional nuclear power order growth rate when excluding SMRs.

Answer

CEO Tom Logan described the nuclear medicine market as strong, driven by the 'Theranostic revolution,' with improving margins from both pricing power and a favorable mix shift to software. CFO Brian Schopfer addressed the order question by stating that while not providing a precise number due to lumpiness, year-to-date order growth in nuclear power remains positive even excluding SMRs. He emphasized that the segment's double-digit revenue growth is the most encouraging sign, as it contains very little SMR contribution.

Yuan Zhi's questions to Verastem (VSTM) leadership

Question · Q2 2025

Yuan Zhi asked about the role of free samples in the initial launch ramp and the expected out-of-pocket costs for patients on commercial and Medicare insurance.

Answer

President and CEO Dan Paterson clarified that there are no "free samples" but a patient assistance program for bridging insurance approval, which has seen very little use. He stated the most used program is co-pay assistance, which results in zero out-of-pocket costs for the majority of commercial patients. For Medicare patients, the annual out-of-pocket limit applies.

Yuan Zhi's questions to OCX leadership

Question · Q1 2025

Asked about the standard testing frequency for transplant rejection, the testing frequency in the company's trial, and the clinical utility and subsequent treatment pathway for detecting subclinical rejection.

Answer

The current market average is about 2.3-2.5 tests per patient under management. The company's clinical trial uses a single time point for its primary endpoint. The key benefit of detecting subclinical antibody-mediated rejection (ABMR) is that effective treatments (like anti-CD38 drugs) are now available, making early diagnosis actionable to prevent graft loss. The test can also monitor treatment response and recurrence.
