Tempus AI
Sequences cancer tumours to tell a doctor which drugs a patient's tumour may respond to, then licenses the anonymised results to drugmakers designing trials.
The scores
Growth3/4 ↓
Not 4: the 83.4% of 2025 was bought, the data line leans on a related party, and Q2 2026 grew 21.6% with nothing acquired.
Business quality3/4 →
Not 4: the network is the largest of its kind, but its only quantified outcomes are the company's own and rivals ship today.
Financial position3/4 ↑
Not 4: it is not net cash and operations still consume cash. Not 2: nothing matures before 2030 and cash interest is close to nothing.

Beat the consensus profit figure in all eight quarters since listing and raised the 2026 guide, but two years is too short to score higher.
Per share capture2/4 ↓
Share-based pay is 14.6% of revenue, three acquisitions were share-funded, and a fourth adds a tenth to a sixth more. No buyback offsets it.
Potential2/4 →

The Verdict
We rate Tempus unattractive. It runs one of America's largest cancer-testing laboratories, and every test also feeds a data library drugmakers pay to use. The business is mixed: much of last year's growth was bought, and a quarter of the data sales come from a company its own founder chairs. The price needs sales to roughly triple by 2029 at a profit margin Tempus has never earned, so it is full, not cheap. As a bet it is fragile: if management's plan works, the shares would be worth only a little more than today; if it fails, about half is left.
The long caseMost cancer patients still get no genomic test, so testing has room to spread, and every test adds data drugmakers pay for; Tempus must turn that into profit.
The evidence under this - 8 claims
- Caris, the closest listed comparison, already earns a positive operating margin on the same kind of business, so the required margin is not unheard of in this industry.
- Gross margin is above 64% and rising, so the margin has to come from operating leverage rather than from pricing, and the company's adjusted profit measure has improved in each of the last several quarters.
- 2026-09-26editedre-struck on the pack refreshed 26 September 2026: the price rose from the $66.17 close of 24 August to $85.01, so enterprise value per dollar of sales is $10.99 rather than $8.70 and the margin the price needs on 2029 revenue is about 25% rather than 20%
- Q2 2026 grew 21.6%, below that rate, and the hereditary half of diagnostics grew 5%.
- The chief executive attached no volume assumption to the figure, and the chief financial officer said on the same call that nothing about volume was implied by it.
- A Medicare list price is not what Tempus is paid across its tests: the average reimbursement was about $1,600 in 2025 (C17) and it had been paid on only about 55% of the oncology tests it ran in 2023 and 2024 (C18).
- The liquid biopsy has no approval yet and he said the timing is 'unknown' between the third and fourth quarter of 2027; neither figure appears in any filing or in the guide.
The company
When someone is diagnosed with cancer, the oncologist has to choose a treatment. Tempus reads the DNA and RNA of the tumour and sends back a report naming the drugs and trials that tumour is likely to respond to. Its main test won FDA approval in 2023.
It sequenced about 367,500 cancer samples in 2025, against 170,300 cases at Caris, a rival. About 205 sales representatives sell into more than 5,000 hospitals and clinics.
The evidence under this - 5 claims
How it makes money
Two ways. Medicare or an insurer pays for each test, about $1,600 on average in 2025, although Tempus was paid on only about 55% of the tests it ran in 2023 and 2024.
Each test also yields an anonymised record linking the tumour to the patient's treatment and outcome, which drugmakers license in bulk. Data and applications brought in $93.2M in the June quarter.
The evidence under this - 4 claims
Where the money comes from, stream by stream
| Stream | Share of sales (FY2025) | How it earns it |
|---|---|---|
| Oncology and other testing | 46.6% | Tumour sequencing and other cancer tests ordered by doctors, paid by Medicare, insurers and drugmakers; the data the business licenses comes from these tests. |
| Hereditary testing | 28.5% | Inherited cancer-risk and rare-disease tests from Ambry, bought in 2025, ordered mainly by genetic counsellors and paid by insurers. |
| Data and applications | 24.9% | Licences of de-identified patient data to drugmakers, plus trial matching and algorithms; a quarter of it in 2026 came from a related party. |
Who runs it
Eric Lefkofsky founded Tempus in 2015 and still runs it; James Rogers has run its finances since 2021. Lefkofsky owns about a fifth of the shares but controls the vote through special shares. Most executive pay rides on sales growth, counting companies bought, and on the share price; nothing rewards cash or profit per share. In 2025 the board paid most of a bonus whose profit goal was missed.
The evidence under this - 4 claims
Since the record date he has sold 700,000 shares under a Rule 10b5-1 plan (C42), and 10,000,000 of the Class A shares sit in a family trust his wife administers, so his economic stake is smaller than the voting figure suggests.
The committee's stated reason has a basis: it says adjusted EBITDA would have been positive without the costs of acquisitions that were not planned when the goal was set.
Revenue growth is measured on reported revenue, so acquired revenue such as Ambry's counts toward the goal; nothing in the plan pays on cash flow, operating profit or revenue per share.
Why it wins, and who could beat it
Why customers come back
The two halves feed each other. Every test adds a record; links into more than 5,000 hospitals and clinics let Tempus join it to what happened to the patient; drugmakers pay for that joined record; and their money funds the software in the report that brings doctors back.
On the company's own measures, data customers spent 26% more in 2025 than in 2024, and 87% of doctors who have ordered more than five tests are still ordering a year later.
The evidence under this - 3 claims
- The measure is the company's own, defined over the data-licensing product alone rather than over all data revenue, and it is disclosed only in a release rather than in an audited filing.
- Roughly a quarter of the data line is a related party whose spending rose sharply in the same period, so part of the increase is spending the chief executive sits on both sides of.
- The measure counts only doctors who already ordered more than five tests, which selects for the ones least likely to leave; nothing is disclosed about the ones who ordered fewer.
- None of Caris, Guardant or NeoGenomics publishes a comparable figure, so it cannot be checked against a rival and is not audited.
The threat
Roche owns the two biggest rivals, Foundation Medicine in testing and Flatiron Health in cancer data, and neither publishes accounts. Caris sells the same tissue report. The subtler threat is Tempus's own making: it delivered an AI cancer model to AstraZeneca, and its risk factors warn that a drugmaker with a model may stop licensing data.
The evidence under this - 4 claims
- AstraZeneca has published nothing confirming delivery or acceptance, so the only account of it is the seller's.
- The company's own risk factors say a completed model could reduce a customer's need to keep licensing data, so delivery is not unambiguously good news for the line it sits in.
- The same arrangement pays Tempus now: AstraZeneca paid a $35M fee and Pathos owes $200M of licence fees, and Tempus keeps a licence to use the finished model.
- Data-licensing revenue grew 36% in Q2 2026 while the model was being built, so no substitution is visible in the line yet.
The rivals: CAI, AZN, NTRA, MYGN, NEO, WGS, GH, IQV, ICLR, and 1 more that is private, in-house or listed abroad.

How big it could get
How big this could get
About 2.11 million Americans will be diagnosed with cancer in 2026. At about $1,600 a test, one test each would be about $3.4B a year. Testing is still rare: 91.4% of Medicare cancer patients from 2016 to 2023 had no genomic test at all.
The evidence under this - 3 claims
Who has signed
AstraZeneca has committed at least $220M through December 2026, rising to $320M through 2028 if it chooses. Pathos AI, chaired by Tempus's founder, owes $200M over three years and may pay half in its own private shares. Other signed data contracts held more than $1.1B at the end of 2025, but customers can cancel for convenience.
The evidence under this - 4 claims
- The extension is AstraZeneca's option and not Tempus's, so the largest named commitment in the file expires inside the horizon unless a customer chooses otherwise.
- Management said on the Q1 2026 call that it has a long history of renewing these agreements at or above where they historically stood; that is a statement about the past and about the company's own reading of it.
The results
The numbers
Sales grew 50% over the twelve months to Jun 2026, slower than the 83% in the year to Dec 2025.
Operating margin is −20%, up from −37% in the year to Dec 2023.
Yearly sales growth has ranged from +30% to +83% over the last 3 years.
Shareholders' money lost 67% a year, up from −89% in the year to Dec 2025.
It used $263M of cash over the last twelve months, so the $600M it holds lasts about 2.3 years at that pace.
The share count rose 189% in 3.5 years, and pay in shares costs 13% of sales.

What growth costs
For years, growing made Tempus less loss-making: research and overhead costs grew slower than sales, helped by a large purchase. In the past year that stopped. Overhead and pay in shares grew as fast as sales or faster, so the loss from running the business got slightly wider rather than narrower.
The evidence under this - 3 claims
2024 is distorted by $534.1M of stock pay recognised at the listing, and the 2025 fall in cost per dollar is partly the Ambry purchase, which added revenue faster than it added research spending.
The last report (30 Jul)
Quarter ended June 2026, filed figures.
The second quarter of 2026 showed the growth without acquisitions: sales up 21.6% to $382.5M. Data and applications grew 28.0%, but a quarter of that line in the first half came from Pathos.
Tempus reported a $5.6M profit, yet it lost $75.9M from operations, more than a year earlier; the profit came from paper gains on shares it holds in Recursion and Personalis. The full-year forecast needs second-half growth of 23.2% to 24.7%.
What it did to the thesisIt confirmed real growth, but also the objection behind the Unattractive view: the operating loss widened, the reported profit came from paper gains on shares it holds, and a large slice of data revenue came from a related party. The forecast still needs faster growth than this quarter delivered.
The quarter in detail
Sales growth from the previous quarter, filed figures.
Earnings per share $-0.04 against $-0.14 expected; $0.03 as filed, the gap being what the company adds back.
The evidence under this - 6 claims
- Data revenue is back-weighted to the second half by the budgeting cycles of pharmaceutical customers, which the 10-Q states plainly, so the shape is normal for this company.
- Roughly $200M of new data bookings were signed in Q2 2026 alone, and the company entered the year with about $350M of contracted value already earmarked for 2026.
What management did with the money
It is buying Personalis for about $1.5B, mostly in its own shares: about 17.9 million new shares at the 25 September price, up to 31.5 million if its price falls, adding 9.9% to 17.3% to the count. Staff were paid $106.8M in stock in the first half, and $1.17B of convertible debt sits against $599.6M of cash.
Insiders in 2026Q2: 14 purchases and 28 sales, from their Form 4 filings.
The evidence under this - 4 claims
- 2026-09-25editedThe S-4 read in full: the terms are restated from the filing rather than the release - the 12.2% Tempus already owns, the $48.42 floor below which the ratio stops rising, and the closing conditions and fees.
- Tempus may pay up to half in cash and told Personalis it wanted that election to control dilution; at the full half the new shares halve, but the cash, about $762M, is more than the $599.6M of cash Tempus held at 30 June 2026, and the S-4 names equity or equity-linked offerings among the ways it could be paid for.
- The count is set by the average price in the 15 trading days before closing, not by any day's close; Tempus closed below $46.00 in late July, so the whole range is live.
- 2026-09-26editedre-struck at the 25 September 2026 close of $85.01 on the refreshed pack, from $82.24 on 24 September: about 17.9 million new shares rather than 18.5 million, 9.9% rather than 10.2%; the ceiling at the fixed ratio is unchanged
The price, and where we disagree
In short. Full. Priced as the platform it may become, not the laboratory-and-data business it is: that needs far bigger sales and a profit margin Tempus has never earned, both at once.
The shares jumped 21% on 19 August on a vaccine result from Merck and Moderna, not on anything Tempus published. Since then two filings have cut the other way: Recursion, a data customer with no tie to management, cut its yearly fee from $42M to $14M, and Tempus's own projections have Personalis losing money until 2030.
The next test is the September-quarter results on November 3.
The evidence under this - 3 claims
- Under the old terms Recursion could terminate for convenience after three years on payment of an early termination fee, so the second $42M was never firm; the new $42M across three years cannot be walked away from.
- At least $4M of each yearly fee is now payable in cash, where the old fees could be paid entirely in Recursion shares (C08).
- The chief executive said on 15 September that the gap to Personalis's $758M is almost entirely the assumed price per test and that Tempus chose to be conservative, so the projections may understate the business.
- Adjusted EBITDA here excludes stock-based pay, and the projections were prepared before signing and are not updated for anything since.
- Tempus's own adviser valued Personalis at $17.00 to $28.55 a share on these projections, above the $16.25 paid, but only because they turn cash-positive in 2034: $556M out from 2026 to 2033 against $2,693M in from 2034 to 2040.
- 2026-09-25editedThe rest of the S-4 read: the note that it was unread is replaced, and the adviser's valuation of these same projections is added as counter-evidence.
How we read the multiple
Counting its debt, buyers pay about $11 for each $1 of Tempus's yearly sales. Rivals' middle is about $7.50, and most of them keep more gross profit per dollar of sales.
To justify that price, Tempus needs:
- About $3.1B of sales in 2029. This year's forecast is about $1.6B.
- About 25 cents of operating profit on each of those dollars, a margin it has never earned.
- This year it expects only about $65M of profit, and that on a measure that leaves out pay in shares.
Against its own history. Too short a public record for its own past to say much. The comparison that carries information is against the rivals its annual report names.
The evidence under this - 4 claims
- Caris, the closest listed comparison, already earns a positive operating margin on the same kind of business, so the required margin is not unheard of in this industry.
- Gross margin is above 64% and rising, so the margin has to come from operating leverage rather than from pricing, and the company's adjusted profit measure has improved in each of the last several quarters.
- 2026-09-26editedre-struck on the pack refreshed 26 September 2026: the price rose from the $66.17 close of 24 August to $85.01, so enterprise value per dollar of sales is $10.99 rather than $8.70 and the margin the price needs on 2029 revenue is about 25% rather than 20%
- The company has raised this guide once already and has beaten the consensus profit figure in each of its eight quarters as a listed company.
- The same measure was negative $7.4M for the whole of 2025, so the guide asks for a $72M swing in one year.
- 2026-09-26editedre-read on the pack refreshed 26 September 2026: still dearer than the middle, 11.0 against a median of 7.45 on enterprise value to sales, third dearest of seven
- 2026-09-26editedre-read on the pack refreshed 26 September 2026: gross margin still second lowest of the seven; Neogenomics, now priced on its profit measures, was already in this comparison

The bet: what it pays if it works
Even if this works, the shares look expensive. The best case we can defend is management's own plan: sales growing by about a quarter each year to 2028, helped by higher test prices and faster data sales. At what rival labs are worth for their sales, that would still be worth only a little more than today's price.
If it fails, a real testing business remains, but its growth looks like its rivals' and a quarter of its data sales come from a company its own chief executive chairs.

A rival-commissioned study sizes US therapy selection near two million profiles a year by 2029; at 35% Tempus tests 700,000, which with flat hereditary and data at 25% a year is about $2.7 billion of revenue. On that forecast, $2.70B pays 1.3× from today's value: an Expensive bet on the market case.
To pay 2× (a Fair bet) it would need about $4.08B of revenue (about 2.3M clinical tests performed); to pay 5× (a Cheap bet), about $10.20B of revenue (about 6.1M clinical tests performed), at the same multiple.

Where we disagree with the market
The AI-native precision-medicine platform: data licensing compounds, the network widens the lead, and 25% growth runs for years.
The growth is slower and lower in quality than the headline: bought in 2025, partly related-party in the data line, slowing elsewhere.
Seeing that takes reading: a related-party note, and one sentence in a February release separating 83.0% reported growth from 33.5% without the acquisition.
We are wrong if data licensing grows above 30% without Pathos, test volume holds above 30% growth, and AstraZeneca extends to 2028.
What analysts say, and the evidence
The evidence under this - 5 claims
- Q2 2026 grew 21.6%, below that rate, and the hereditary half of diagnostics grew 5%.
- The chief executive attached no volume assumption to the figure, and the chief financial officer said on the same call that nothing about volume was implied by it.
- The extension is AstraZeneca's option and not Tempus's, so the largest named commitment in the file expires inside the horizon unless a customer chooses otherwise.
- Management said on the Q1 2026 call that it has a long history of renewing these agreements at or above where they historically stood; that is a statement about the past and about the company's own reading of it.
What could go wrong, and how we would know
The risks
- A renewal that decides the case. AstraZeneca's agreement ends on 31 December 2026, and extending it is AstraZeneca's choice.
- Revenue from the founder's company. Pathos supplied 24.2% of the data line in the first half, and may pay up to half its fees in private shares.
- Its own model as competitor. A drugmaker that owns a model trained on Tempus data may stop licensing the data.
- Getting paid. Tempus was paid on only about 55% of its cancer tests, and Medicare pays nationally only for FDA-approved uses.
The evidence under this - 7 claims
- The extension is AstraZeneca's option and not Tempus's, so the largest named commitment in the file expires inside the horizon unless a customer chooses otherwise.
- Management said on the Q1 2026 call that it has a long history of renewing these agreements at or above where they historically stood; that is a statement about the past and about the company's own reading of it.
- The same arrangement pays Tempus now: AstraZeneca paid a $35M fee and Pathos owes $200M of licence fees, and Tempus keeps a licence to use the finished model.
- Data-licensing revenue grew 36% in Q2 2026 while the model was being built, so no substitution is visible in the line yet.
What we still do not know
- Whether AstraZeneca extends its agreement to 2028.
- How many new shares the Personalis deal creates; that depends on Tempus's price before it closes.
- Whether the $80M to $100M the chief executive expects from Medicare pricing arrives. It is in no filing and not in the forecast.
The evidence under this - 3 claims

- Tempus may pay up to half in cash and told Personalis it wanted that election to control dilution; at the full half the new shares halve, but the cash, about $762M, is more than the $599.6M of cash Tempus held at 30 June 2026, and the S-4 names equity or equity-linked offerings among the ways it could be paid for.

Since we wrote this
- 26 OctNewsBristol and Pathos data deals add $192.5M, $55M of it related-party. View heldTempus signed $192.5M of data agreements with Bristol Myers Squibb and Pathos (8-K, 23 October); European IVDR certification for the xR test.
- 5 OctThesis reviewThe bet now names what it ridesThe owner asked that every bet name the macro trend behind it, after BWXT's bet was missing its chief executive's case for nuclear over gas.
- 4 OctThesis reviewOwner's checklist: revenue streams, cost of growth, management, catalystsThe owner's checklist found the method silent on who runs the company, what growth costs, where the money comes from and what is dated ahead; this pass fills those four blocks from the proxy and filings.
- 26 SepThesis reviewRelated-party share put at 24.2% of data line; view heldThe summary of what would change our view said a tenth of the data line came from Pathos, the chief executive's other company. The filing gives 24.2% in the first half, double a year earlier.
- 26 SepThesis reviewShares up 28%; the price now needs a 25% marginA data fix refreshed the numbers. At $85.01 the price needs about a 25% operating margin by 2029, not 20%, against a best of minus 16.7%, and the rivals' comparison is unchanged.
- 25 SepNewsPersonalis deal adds a tenth to a sixth more shares. View heldThe full merger filing changes how much of the company each holder keeps, not what the company earns, so the per-share objection sharpens and the view stands.
- 24 SepNewsA data customer cut its fee; Personalis loses money. View heldRecursion, a customer with no tie to management, cut its yearly fee by two thirds, and Tempus's own plan has Personalis losing money until 2030. Both sharpen the objection.
- 25 AugThesis writtenUnattractive, medium convictionWritten after a 54.2% rise in twenty trading days, much of it on another company's vaccine trial result.
