UnitedHealth says it’s working with feds on Medicare probe

UnitedHealth Group is responding to requests from the Department of Justice regarding its Medicare Advantage business, the company disclosed in a regulatory filing Thursday morning.

Before this, the company had proactively reached out to the government after The Wall Street Journal reported that it was being probed. UnitedHealth is now “complying with formal criminal and civil requests” from the DOJ.

“The Company is committed to maintaining the integrity of its business practices and serving as reliable stewards of American tax dollars,” it said in the filing.

The company’s insurance arm, UnitedHealthcare, offers Medicare Advantage, a program where those eligible for government healthcare can get it through a private company and the government reimburses most of the bill. But according to previous reporting from the Journal, which appears to have sparked the DOJ probe, the company often overdiagnoses patients on the program to trigger larger payments from the government.

UnitedHealth fell 4% in premarket trading. It’s down more than 40% for the year.

The confirmation of the investigation adds to UnitedHealth’s growing list of issues.

The head of its insurance arm, Brian Thompson, was killed in Manhattan in December in a high-profile shooting. The company ousted its CEO in May amid reports of increased scrutiny from the government. And the probes confirmed on Thursday are in addition to last year’s antitrust investigation into the company.

Planet Labs slips after big post-earnings gain

Smallish midcap satellite imagery and data company Planet Labs is giving back a chunk of the nearly 50% gain it racked up after posting earnings early Monday.

No tears, though: the shares, which seem to have a fairly robust retail following, are still up roughly 340% over the past 12 months.

CoreWeave soars as Microsoft’s deal with Nebius shows unrelenting demand for AI compute

CoreWeave is soaring as Microsoft’s $17.4 billion deal with Nebius shows the immense value and continued demand for all parts of the AI data center ecosystem.

One additional reason for CoreWeave’s jump may be that its pending acquisition of AI data center infrastructure company Core Scientific looks like a great deal compared to Microsoft’s renting of (more broad and advanced) AI data center capacity from Nebius.

CoreWeave’s all-stock deal to buy Core Scientific was initially valued at ~$9 billion, but with the subsequent decline in its shares, it’s worth about 40% less. And in purchasing Core Scientific, CoreWeave is saving $10 billion in what it would have paid the company to lease data center infrastructure over the next 12 years.

As it stands, Microsoft is getting about 300 megawatts in data center power capacity from Nebius, while Core Scientific boasts that its footprint is in excess of 1,300 megawatts. So, on the surface, it looks like an absolute steal for CoreWeave.

But again, this is not an apples-to-apples comparison; not all access to AI computing infrastructure is created equal.

There are differences in the type of AI infrastructure provided by the two: Nebius owns GPUs, while Core Scientific doesn’t, and what it provides in the software layer isn’t offered by Core Scientific as a stand-alone entity. This is the difference between the “full stack” approach (Nebius) and a “colocation” approach (Core Scientific).

That being said, CoreWeave’s acquisition of Core Scientific, once completed, will make the combined entity’s business model look more like Nebius’ model, which, as Microsoft just told us, is something that top hyperscalers are willing to pay a pretty penny for.

UNH rises after preliminary data shows most Medicare Advantage enrollees will be on more lucrative, top-rated plans

UnitedHealth rose more than 4% in premarket trading on Tuesday after the company disclosed that it expects the majority of its Medicare Advantage enrollees will be on plans rated four stars or higher in 2026.

Though the data is only preliminary, about 78% of UNH’s Medicare Advantage members are in plans rated four stars or higher, the company said in a regulatory filing Tuesday morning. On Monday, the company said it plans to reiterate its full-year guidance when it meets with investors this week.

Insurance companies that provide government-sponsored plans, like Medicare Advantage, have struggled this year amid unexpected rising costs. Plans that are rated four stars or higher earn bonus payments and are typically more lucrative for healthcare insurance providers.

Retail darling Planet Labs soars on earnings pop for second straight quarter

Planet Labs, which operates a network of satellites that record data, images, and information about the Earth, surged more than 40% after reporting better-than-expected quarterly numbers before the open of trading Monday.

It was the second straight quarter when the money-losing company’s quarterly update generated a massive market reaction. The stock jumped nearly 50% after numbers came out in June.

The company, which went public via SPAC in 2021, raised its full-year revenue guidance and notched its second straight quarter of positive free cash flow. Analysts and investors watch free cash flow closely as it can signal when a company’s business is starting to become more durable.

While the company is small — roughly $2.5 billion in market cap — it has posted pretty serious gains, rising almost 300% the past 12 months. Planet Labs also appears to have a fairly large retail shareholder base.

Just 57% of its float is in the the hands of institutional investors, according to FactSet data. That’s roughly the same as other retail favorites such as Palantir, though Planet Labs is no where near as highly valued as the defense data and AI software company led by CEO Alex Karp.
