The brief
- 2025 revenue was about USD 1.27B (+83%, helped by buying Ambry Genetics); 2026 guidance USD 1.595-1.605B.
- FDA approved its 648-gene xT CDx test for tumour-only use in May 2026, on top of the 2023 tumour-plus-normal approval.
- Agreed in July 2026 to buy Personalis, maker of a cancer-recurrence blood test, for about USD 1.5B.
Technical approach
Sequence the tumour, report the options
Tissue and blood tests read hundreds of cancer genes and flag mutations that match approved drugs or open trials for that patient.
Every test feeds a data library
De-identified test results are joined with treatment and outcome records, then licensed to drug makers for research and trial design.
Models trained on that library
Tempus builds AI tools, such as Paige Predict for pathology slides and an oncology foundation model built with AstraZeneca and Pathos.
From diagnosis to relapse
Hereditary tests (Ambry) and blood tests for leftover cancer (Personalis's NeXT Personal) extend coverage before and after treatment.
