Clearwater Analytics Holdings, Inc. (CWAN) had itself a morning in premarket trading, jumping roughly 8% after landing what you might call a pretty substantial deal.

The news? A consortium of private equity heavyweights, led by Permira and Warburg Pincus, announced they're buying the investment and accounting software company for approximately $8.4 billion, including debt. That's the kind of Sunday announcement that makes Monday morning a lot more interesting for shareholders.

Clearwater Analytics shares climbed 7.6% to $23.93 in premarket trading as investors digested the buyout news.

But Clearwater wasn't alone in making waves before the opening bell. Here's a look at the other stocks putting up notable moves in premarket action.

The Gainers

Autozi Internet Technology (Global) Ltd. (AZI) surged 60% to $4.00 in premarket trading. The company continued its Friday rally after announcing that its strategic investor confirmed a $90 million initial equity investment. Friday alone saw shares jump 64%, so the momentum appears to be holding.

Datavault AI Inc. (DVLT) surged 34.8% to $1.31 in premarket trading. The catalyst? Datavault AI announced the issuance of two foundational U.S. patents advancing blockchain-driven content licensing and tokenized monetization. Patent news doesn't always move the needle this much, but apparently these ones caught investors' attention.

Vision Marine Technologies Inc. (VMAR) rose 30.3% to $0.3270 in premarket trading. Vision Marine Technologies announced the closing of a public offering on Friday, which typically dilutes existing shareholders but also brings fresh capital to the company.

Sidus Space, Inc. (SIDU) rose 20.7% to $1.40 in premarket trading, building on Friday's 35% surge. The momentum train is clearly still rolling for this one.

Hycroft Mining Holding Corporation (HYMC) gained 14.2% to $18.77 in premarket trading after posting a 7% gain on Friday. Another case of Friday's winners keeping the party going.

Tharimmune, Inc. (THAR) gained 14.2% to $2.65 in premarket trading after adding around 5% on Friday.

Creative Media & Community Trust Corporation (CMCT) shares jumped 13.2% to $3.61 in premarket trading after gaining 7% on Friday.

Digital Ally, Inc. (DGLY) rose 10.4% to $0.80 in premarket trading, bouncing back after falling 11% on Friday. A nice reversal for anyone who bought the Friday dip.

ABIVAX Société Anonyme (ABVX) gained 10.2% to $126.64 in premarket trading.

The Losers

Luminar Technologies, Inc. (LAZR) fell 54.8% to $0.2728 in premarket trading, giving back most of Friday's spectacular 175% rally. The whipsaw makes sense when you remember that Luminar announced last week it's entering voluntary Chapter 11 bankruptcy proceedings to pursue court-supervised sale processes for its core businesses. Friday's surge was likely speculative trading on potential asset sales, but the reality of bankruptcy appears to be setting back in.

Mint Incorporation Limited (MIMI) fell 14.4% to $0.41 in premarket trading, cooling off after jumping more than 75% on Friday.

Amesite Inc. (AMST) tumbled 12.8% to $2.32 in premarket trading after gaining more than 15% on Friday. Another case of Friday's gains getting trimmed on Monday morning.

Culp, Inc. (CULP) fell 10.1% to $3.11 in premarket trading. Culp recently reported mixed second-quarter financial results, which apparently didn't inspire confidence among early-morning traders.

Rising Dragon Acquisition Corp. (RDAC) declined 9.5% to $9.42 in premarket trading. The company announced a trust amendment reducing its monthly extension fee, which you'd think might be viewed positively, but the market had other ideas.

Hyperscale Data, Inc. (GPUS) fell 9.2% to $0.2335 in premarket trading after announcing an "at-the-market" offering of common stock. Dilution worries tend to weigh on shares, and this case was no exception.

DBV Technologies S.A. (DBVT) dipped 8.3% to $20.88 in premarket trading after gaining more than 5% on Friday.

Vivakor, Inc. (VIVK) shares dipped 7.8% to $0.0688 in premarket trading.

CureVac N.V. (CVAC) dipped 3.6% to $4.01 in premarket trading after declining 3% on Friday, extending its losing streak.

Regencell Bioscience Holdings Limited (RGC) fell 3% to $19.25 in premarket trading after gaining 5% on Friday.

Premarket trading can be a wild ride, with lower volume often amplifying moves in both directions. Whether these gains and losses hold once regular trading begins is anyone's guess, but it's certainly setting up for an interesting opening bell.
