Tempus AI slides after missing Q4 EBITDA target

Cancer diagnostics company and sometimes retail shareholder favorite Tempus AI reported soft Q4 adjusted EBITDA numbers late Tuesday, sending shares lower in the after-hours session. 

It reported: 

  • Q4 revenue of $367.2 million vs. FactSet’s expectation of $362.8 million.

  • An adjusted loss per share of $0.04 vs. the $0.04 loss estimated.

  • Adjusted EBITDA of $12.9 million vs. expectations for $22 million, per FactSet.

Since going public in June 2024, Tempus has been a volatile stock that has both doubled — and cratered — on multiple occasions. That spectacle has at times captured the attention of retail traders who’ve tried to ride the waves.

Of late, the wave has been breaking bad, with shares down more than 30% since the stock hit a record high on October 8, 2025

Still, the company is now adjusted EBITDA positive. That, CEO Eric Lefkofsky told us last year, is the first milestone on Tempus’ journey to profitability, a mark that analysts think will take until at least next year for the company to hit.

Lucid reports Q4 earnings miss, revenue beat

Luxury EV maker Lucid reported its fourth-quarter earnings after the bell Tuesday. Shares fell more than 6% in after-hours trading.

The company posted an adjusted loss of $3.08 per share, wider than the $2.63 loss expected by analysts polled by FactSet. Lucid booked $522.7 million in revenue, beating the consensus estimate of $459.5 million.

Lucid issued a full-year 2026 production outlook of between 25,000 to 27,000 vehicles, representing 40% to 51% growth from 2025’s figures. Lucid downwardly revised its full-year 2025 production numbers from 18,378 to 17,840 vehicles due to internal validation issues.

The company maintained the timeline of its unnamed midsize SUV due to begin production later this year. That schedule puts it close to rival Rivian’s planned second-quarter release of its R2 SUV.

Lucid did not issue an update to its ongoing CEO search. The company has been led by interim CEO Marc Winterhoff for the past year, after it abruptly announced in its fourth-quarter 2024 report that then CEO Peter Rawlinson would step aside.

The stock has fallen to all-time lows this month and is down 98% from its high in 2021. Last week, the company announced it would lay off 12% of its US workforce in an effort to improve profitability.

Sandisk sinks more as product release underwhelms market

Sandisk’s online event marking its one-year anniversary since being spun off from Western Digital seems to be something of a damp squib.

The shares, already down a fair bit following the Citron Research short announcement, fell further after the company announced an upgrade to its consumer solid state memory drives alongside a YouTube-based presentation aimed at highlighting all the things one might do with, well, access to additional digital storage.

The stock — which is still up more than 150% in 2026 — was down more than 7% shortly after the company’s post at 2 p.m. ET. That was in stark contrast to the bump software stocks were riding following Anthropic’s product announcement earlier on Tuesday.

Sandisk slides on Citron short announcement

Sandisk’s roughly 1,200% run-up over the last year — it was spun off from Western Digital exactly a year ago — took a breather early Tuesday, after well-known stuff-stirrer Citron Research, short seller Andrew Left’s firm, announced it was short the stock.

In a post on X, Citron suggested that while Sandisk has benefited from the parabolic price increase for memory chips, it’s only a matter of time before giant contract chip manufacturers like Samsung Electronics and TSMC turn on the taps:

“The market is pricing SanDisk like it’s $NVDA. There’s one problem: NVIDIA has a moat. SanDisk sells a commodity. We’ve seen this movie before 2008, 2012, 2018. It’s never different this time. Memory is a cycle, and cycles peak.”

That’s true historically speaking, but Wall Street seems to see the memory price spike continuing for at least a couple more years. Analysts have ratcheted up their earnings expectations over the next few years, in line with the guidance Sandisk issued in its latest earnings report. And shorting a stock with this much momentum — it’s up more than 150% this year alone! — is treacherous indeed.

Citron Research on X: "Citron is Short $SNDK — They Don't Ring a Bell at the Top We don't need Anthropic to announce they're making NAND. Samsung is already the 800-pound gorilla...

Citron Research on X: "Citron is Short $SNDK — They Don't Ring a Bell at the Top We don't need Anthropic to announce they're making NAND. Samsung is already the 800-pound gorilla, and they've been running this playbook for 30 years. While TV pundits pound the table herding retail into cattle cars," / X
