Dated 2026-10-22

Why it matters: Organic requisition volume grew 14.4% in Q3, while revenue per requisition fell 4.2%. Volume growth helps offset that lower revenue per order.
Watch forOrganic requisition volume grows at least 10% from the same quarter last year.
Also watch forOrganic requisition volume is flat or falls year over year in the next reported quarter.
Why it matters: Quest signed a deal for select outreach lab assets. Closing would add customer access; a failed or delayed deal would stall that step.
Watch forQuest announces that it closed the deal for the Northeastern health system's select outreach lab assets.
Also watch forQuest announces that the deal ended, or reports that it will not close on agreed terms.
Why it matters: Quest moved Project Nova into its build phase. The first lab launch will test whether the plan stays on schedule.
Watch forQuest deploys Epic solutions in its first lab by fall 2027, as planned.
Also watch forQuest reports a delay beyond fall 2027 or cancels the first lab launch.
Why it matters: Quest raised its revenue range after strong organic growth. Meeting or beating the new low end would confirm that pace continued.
Supportive ifFull-year 2026 revenue is at least $12.065 billion, the low end of the October range.
Worry ifFull-year 2026 revenue is below $12.065 billion, or Quest cuts the range before reporting results.
