Tempus AI, Inc. agreed to acquire Personalis, Inc. through a two-step merger structure. Merger Sub I will merge into Personalis, which will then merge into Merger Sub II, leaving Merger Sub II as a wholly owned subsidiary of Tempus. Personalis stockholders’ shares will be converted into the right to receive Tempus Class A common stock, with an exchange ratio based on the volume-weighted average price of Tempus Class A common stock over fifteen consecutive trading days before closing, or on per-share consideration in a specified Tempus transaction. The parties intend the deal to qualify as a tax reorganization under Section 368(a).
Closing is subject to Personalis stockholder approval, Nasdaq listing of the Tempus shares issued in the merger, effectiveness of a Form S-4 registration statement, HSR and other antitrust clearances, tax opinions, accuracy of representations, covenant compliance, and absence of specified material adverse effects. Personalis is bound by a no-shop covenant but may consider a Superior Proposal subject to notice, matching rights and, in certain cases, payment of a termination fee. Personalis may terminate if the Tempus Stock Price is below a $46.00 lower floor price during a short window before closing. If the Merger Agreement is terminated in certain circumstances, Personalis must pay Tempus a $76.8 million termination fee, and Tempus must pay Personalis a $76.8 million reverse termination fee if regulatory-related conditions fail primarily due to Tempus’ breaches and closing has not occurred by an initial outside date of April 20, 2027, subject to possible extensions.
Tempus AI, Inc. entered into a definitive agreement to acquire Personalis, Inc., valuing Personalis at an enterprise value of $1.5 billion, with shareholders receiving $16.25 per share.

The consideration is a 100% stock transaction, with Tempus able to elect cash for up to 50% of the consideration; Personalis holders will receive a floating exchange ratio of Tempus shares, capped at 0.3356 per Personalis share. The price reflects a 6% premium to the prior closing price and a 28% premium to the unaffected 30‑day VWAP. Closing is expected in late 2026 or early 2027, subject to Personalis shareholder and regulatory approvals. Personalis reported preliminary Q2 revenue of $22.4 million and 10,384 clinical tests, a 33% sequential volume increase, highlighting MRD momentum in a cited $20 billion market opportunity.
