Tempus AI (TEM) Stock Price Performance: Last 30 Days vs. Quarter
Over the last 30 days, TEM advanced roughly 70%, from a closing price of $41.55 on July 29, 2026, to $70.69 on August 27, 2026. The move was concentrated in mid-August, when the shares surged more than 20% in a single session following the Merck–Moderna oncology readout.
The last quarter tells a more volatile story. From roughly $51 in late May 2026, the stock first rallied toward $61.60 in early July, then pulled back about 33% to its late-July low near $41.55, and finally rebounded to $70.69 by late August—a net gain of roughly 38% over the period. This choppy pattern reflects shifting sentiment across AI and healthcare technology names.
What Drove TEM Stock Price in the Last 30 Days
The dominant catalyst was oncology news rather than a company-specific earnings event. On August 19, 2026, Merck (MRK) and Moderna (MRNA) announced that their Phase 3 INTerpath-001 trial of the personalized mRNA cancer therapy V940 combined with Keytruda met its recurrence-free survival endpoint in melanoma. Because Tempus's pending acquisition of Personalis (PSNL) brings in-house the sequencing platform that has supported the V940 program, investors interpreted the result as validation of the deal, sending TEM up about 24%.
Regulatory momentum added support. Tempus received FDA clearance for Tempus ECG-PH, an AI tool that flags signs of pulmonary hypertension from standard ECGs—its third cardiovascular clearance—and earlier secured FDA approval for its tumor-only xT CDx companion diagnostic, which enables unified Advanced Diagnostic Laboratory Test pricing and an estimated $85 million in annual revenue uplift beginning in 2027. BTIG analyst Mark Massaro also raised his price target on the stock to $80 from $70, citing the sequencing opportunity tied to the cancer-vaccine program.
Fundamentals underpinned the advance. In its second-quarter report, Tempus posted revenue of $382.5 million, up 22% year over year, achieved its first quarterly GAAP net profit of $5.6 million, and raised full-year 2026 revenue guidance to $1.595–$1.605 billion.
What Drove TEM Stock Performance Over the Last Quarter
The quarterly trend was shaped by a mix of operational execution and shifting risk appetite. Tempus announced its agreement to acquire Personalis for $1.5 billion in July, positioning the company to internalize MRD testing and next-generation sequencing. During the quarter it also delivered strong second-quarter results, raised guidance, completed a $460 million zero-coupon convertible-note offering, and expanded its data business with agreements including AstraZeneca and BioNTech, while data licensing and modeling revenue grew 36% year over year.
The mid-quarter pullback reflected profit-taking and broader volatility in richly valued AI and healthcare technology stocks, along with investor concerns about dilution and integration risk tied to the Personalis transaction. The August recovery, in turn, was driven by the clinical validation of that acquisition and by a series of regulatory milestones.

TEM Stock Forecast Drivers: What Investors Should Watch Next
Investors will be watching the integration of Personalis, a transaction expected to close in late 2026 or early 2027, along with the ramp of MRD testing, which reached roughly 9,000 tests in the second quarter, up 38% sequentially. Reimbursement developments will also matter: the migration of Tempus's solid-tumor DNA portfolio to ADLT pricing, the anticipated FDA decision on its xF liquid biopsy assay in the latter half of 2027, and broader payer coverage could all influence revenue and margins. Competitive dynamics in genomics and diagnostics, including progress from Guardant Health (GH) and Natera (NTRA), and any dilution or financing considerations tied to the acquisition remain key factors for investors to monitor.
