Ulta Beauty, Inc. (ULTA) shares jumped sharply in premarket trading Friday after the beauty retailer delivered third-quarter results that handily beat expectations and raised its full-year earnings outlook. When a company surprises Wall Street by that much, investors tend to notice.

The numbers tell the story: Ulta Beauty reported quarterly earnings of $5.14 per share, crushing the analyst estimate of $4.54 by 13.27%, according to Benzinga Pro. Revenue came in at $2.858 billion, topping the Street estimate of $2.72 billion and marking a solid increase from $2.53 billion in the same period last year. That's the kind of beat that gets rewarded quickly.

Ulta Beauty (ULTA) shares climbed 5.7% to $564.16 in premarket action, adding to what's been a volatile year for the retailer.

But Ulta wasn't alone in making big moves before the market opened. Here's a look at 19 other stocks experiencing significant premarket swings.

The Big Winners

Lion Group Holding Ltd. (LGHL) rocketed 57.3% to $6.89 in premarket trading. The stock had fallen more than 15% on Thursday after the company announced a $10 million private placement aimed at funding Bitcoin acquisition. Apparently, investors had second thoughts overnight.

SMX (Security Matters) Public Limited Company (SMX) surged 42.9% to $201.47 in premarket trading, continuing its momentum after a 141% jump on Thursday. The company held its annual general meeting in Dublin earlier this week, where shareholders voted on 16 proposals. All 16 were approved by a majority, with 347,442 ordinary shares represented at the meeting, according to a Form 6-K filed with the Securities and Exchange Commission Wednesday.

Inno Holdings Inc. (INHD) rose 37.3% to $0.1907 in premarket trading, though no specific catalyst was immediately apparent for the move.

Akanda Corp. (AKAN) gained 30.1% to $1.23 in premarket trading after shareholders approved a share consolidation proposal, according to an SEC filing submitted Tuesday. Share consolidations—reverse splits, in other words—don't always get this kind of reception, but markets can be unpredictable.

SciSparc Ltd. (SPRC) rose 23.2% to $2.18 in premarket trading, building on a roughly 4% gain from Thursday.

Concord Medical Services Holdings Limited (CCM) gained 17.5% to $4.17 in premarket trading, bouncing back after a 6% decline on Thursday.

Rubrik, Inc. (RBRK) rose 16.5% to $82.10 in premarket trading after the data security company reported third-quarter results that beat both earnings and sales estimates. It's always nice when you exceed expectations on both lines.

Zumiez Inc. (ZUMZ) jumped 14.1% to $31.10 in premarket trading after the action sports retailer reported strong results for the third quarter and issued an encouraging fourth-quarter sales outlook. Positive guidance tends to help.

The Cooper Companies, Inc. (COO) gained 13.4% to $87.35 in premarket trading after the medical device company reported better-than-expected fourth-quarter financial results and issued fiscal 2026 guidance above estimates.

The Decliners

Sportsman's Warehouse Holdings Inc. (SPWH) tumbled 18.8% to $1.99 in premarket trading after reporting third-quarter results that apparently disappointed investors.

Protara Therapeutics Inc. (TARA) declined 14.3% to $5.89 in premarket trading after the biotech company announced the pricing of a $75 million public offering. New share offerings tend to dilute existing shareholders, which explains the market's reaction.

Rich Sparkle Holdings Ltd. (ANPA) fell 11% to $19.50 in premarket trading, giving back some of Thursday's more than 40% surge.

VCI Global Ltd. (VCIG) dipped 10.3% to $1.05 in premarket trading. VCI Global (VCIG) shares had jumped 23% on Thursday after the company approved the spin-off of its V Capital Consulting unit at a $168 million valuation.

Agencia Comercial Spirits Ltd. (AGCC) dipped 9.8% to $8.01 in premarket trading after surging 24% on Thursday.

Hewlett Packard Enterprise Co. (HPE) fell 9.2% to $20.80 in premarket trading after the tech company reported mixed fourth-quarter financial results and issued weak first-quarter sales guidance. When you miss on guidance, the market tends to punish you for it.

Polyrizon Ltd. (PLRZ) fell 8.5% to $13.27 in premarket trading, pulling back after a 105% jump on Thursday. Polyrizon had shared new preclinical data Wednesday showing its proprietary naloxone hydrogel adheres to nasal tissue longer than an approved and marketed intranasal naloxone spray product.

SentinelOne Inc. (S) fell 8% to $15.61 in premarket trading after the cybersecurity company reported third-quarter financial results and narrowed its fiscal 2026 sales guidance below estimates.

Oklo Inc. (OKLO) dipped 6.6% to $104.30 in premarket trading after the nuclear energy company entered into an equity distribution agreement to offer up to $1.5 billion of common stock. That's a substantial potential dilution.

DocuSign Inc. (DOCU) fell 5.5% to $67.21 in premarket trading following the release of third-quarter results.
