Company snapshot
CareDx provides diagnostic solutions for transplant patients and caregivers, which include donor-derived cell-free DNA tests, gene expression tests (AlloMap Heart), and transplant patient management software. The company generates revenue through direct sales and third-party distributors, offering both testing services and software products to healthcare providers and transplant centers.
What this transaction means for investors
The shares Hanna Jr. sold were part of a Rule 10b5-1 plan, under which the sales were planned in advance. He sold another 10,156 shares a week earlier under the same plan, which was $214,292 at the time. Regardless, those sales shouldn’t affect investors’ decision to purchase the stock.
On Jan. 12, 2026, CareDx announced its preliminary fourth-quarter results for FY 2025, reporting Q4 revenue of $108 million, 25% year-over-year, beating analyst expectations. It expects its testing services to grow strongly and record revenue throughout 2026, including its AlloSure Kidney solution, which can detect early signs of potential transplant rejection or injury in kidney transplant patients. The other testing service it’s going to lean on is AlloMap Heart, which essentially uses the same concept but for the heart.
After an underwhelming performance in 2025, CareDx’s stock rose approximately 9% in January 202. But for long-term investment potential, CareDx will have to deliver strong results for its testing solutions.
