Why is Adaptive Biotechnologies Corporation Common Stock (ADPT) stock moving?

Adaptive reported Q3 2026 results on Nov 4 with revenue of $83.9M, which beat the roughly $71.6M consensus, and MRD revenue rose 28% (44% excluding milestones). The company reached total profitability for the quarter, with adjusted EBITDA of $14.3M and free cash flow of $7.7M, and raised full-year MRD revenue guidance to $276M-$286M, implying 30%-35% growth. Adjusted EPS of $(0.13) missed the $(0.10) estimate, and reported headline revenue fell 11% year over year because of Genentech Agreement timing. Clinical and guideline news is supportive: NCCN added an MRD framework for multiple myeloma including annual maintenance testing, and IMWG introduced a cure definition that requires MRD negativity, and a MolDX technical assessment is pending for an additional Medicare bundle. Guggenheim kept its Buy rating and lifted its target to $34 on Nov 10. Price action fits this story: the stock rose from $24.41 (Oct 22) to a $28.37 close on Oct 28, dipped to $25.06 after heavy volume on Oct 30 and Nov 2, rallied into earnings and through Nov 9 (+8.1% on 2.83M shares, close $30.26), then eased to $29.36 on Nov 10 after an intraday high of $30.81. A Telo Genomics comparative study is a competitive watch item, and the immune medicine separation remains open.

News behind the analysis

About Adaptive Biotechnologies Corporation Common Stock

Healthcare · Diagnostics & Research (immune-medicine biotech)

Adaptive Biotechnologies is a Seattle company that reads the genetic sequences of immune cells (T-cell and B-cell receptors) to diagnose and track disease. Its main product, the clonoSEQ test, uses this technology to detect minimal residual disease (MRD): tiny amounts of cancer left in patients with blood cancers such as multiple myeloma, leukemia and lymphoma.

How it makes money

Most revenue comes from its MRD business. That includes clonoSEQ tests billed to Medicare and private insurers, plus MRD testing sold to drug companies for their clinical trials. MRD revenue is guided at about $276–286M for 2026 (roughly 30–35% growth), and the company delivered about 40,000 clonoSEQ tests in Q3 2026. A smaller Immune Medicine unit earns money from drug-discovery partnerships, most notably a collaboration with Genentech that has paid milestone fees. Total revenue was about $277M in 2025. The company had its first profitable quarters recently (Q3 2025 and Q3 2026) but has a long history of losses. It also carries $345M of convertible notes issued in 2026.
