Mumbai, Sept 30: US-listed stocks saw some sharp moves on Tuesday as investors responded to a mix of earnings updates, buyout announcements, new contracts and business partnerships. Carnival shares climbed following its latest earnings update, while SoundThinking surged after news of a proposed buyout. BIO-key also recorded a strong gain after announcing new partnerships. Elsewhere, several companies moved on developments ranging from infrastructure deals and strategic investments to corporate actions and IPO plans. The varied price movements reflected how individual company announcements continued to drive trading activity across different sectors. 

Carnival Shares Jump Over 12% as Earnings Beat and 2027 Bookings Lift Sentiment 

Carnival Corporation’s (NYSE: CCL) shares rose sharply on Tuesday after the cruise operator reported stronger-than-expected third-quarter results and highlighted record booking levels for 2027. The company reported adjusted earnings of $1.43 per share, above the analyst estimate of $1.35, while revenue reached $8.44 billion, exceeding the $8.39 billion consensus. 

The company also raised its full-year adjusted net income outlook by more than $150 million from its June guidance, despite an additional $150 million in fuel costs. Record net yields, higher customer deposits and record booked occupancy and pricing for 2027 added to the positive market response. 

Carnival shares opened at $24.39 on September 29, compared with the previous session’s close of around $22.14, indicating a strong gap-up following the earnings announcement. As of 10:53 a.m. ET, the stock was trading at $24.93, up $2.79, or 12.53%. The stock had touched an intraday high of $25.16 and a low of $24.00 so far. 

The move represents a marked shift from the previous session, when Carnival closed at $22.14 after declining 0.49%.  

SoundThinking Shares Surge 50.82% After Transom Capital Acquisition Deal 

SoundThinking (Nasdaq: SSTI) shares surged 50.82% on Tuesday after the company agreed to be acquired by Transom Capital Group for $8.00 per share in upfront cash, plus a non-transferable contingent value right (CVR) worth up to an additional $3.00 per share. The transaction could therefore provide total consideration of up to $11.00 per share, subject to the CVR conditions. 

The $8.00 upfront payment represents a 46% premium to SoundThinking’s September 28 closing price of $5.47, while the maximum $11.00 consideration would represent a 101% premium. The CVR payments are linked to 2027 revenue milestones for the company’s ShotSpotter and SafePointe products. 

SSTI shares opened at $8.30 on September 29, compared with the previous session’s close of approximately $5.47. The stock climbed to an intraday high of $8.43 and touched a low of $8.24. 

As of 12:15 p.m. ET, SoundThinking was trading at $8.25, up approximately 50.82% from the previous close. The shares remained above the transaction’s $8.00 upfront cash consideration during the reported session. 

The transaction has received support agreements from shareholders representing approximately 33% of SoundThinking’s outstanding shares, while the company expects the deal to close in the fourth quarter of 2026, subject to customary conditions. Following completion, SoundThinking is expected to become privately held and cease trading on Nasdaq. 

BIO-key Shares Surge 71.53% as UAE-Saudi Arabia Partnership Puts BKYI in Focus 

BIO-key International has entered into a strategic partnership with Dubai-based Al Majlis Group to pursue identity security opportunities across government and private-sector organisations in the UAE and Saudi Arabia. The agreement combines Al Majlis Group’s regional relationships with BIO-key’s biometric identity and access management technology. 

The announcement triggered a sharp move in BIO-key International (NASDAQ: BKYI) shares during Tuesday’s session. The stock was trading at around $2.89, up 71.53% from the previous close of $1.68, based on market data available at around 12:21 p.m. ET. The shares opened at $3.37 and had so far traded between an intraday high of $4.66 and a low of $2.76. 

The wide trading range indicates significant volatility following the partnership announcement. BKYI had closed at $1.68 on Monday after trading between $1.65 and $1.96 during that session. 

Under the partnership, the companies will initially approach selected government and private-sector organisations in the two Gulf markets. BIO-key said its technology supports cloud and on-premises deployments and currently secures access for more than 40 million users. 

However, the companies did not disclose contract values, customer commitments or expected revenue from the arrangement. As a result, the commercial impact will depend on whether the initial engagement leads to customer deployments and revenue.

CarMax Shares Rise as Earnings Beat Estimates and Buyback Plans Support Market Response 

CarMax (NYSE: KMX) shares moved higher on Tuesday after the used-car retailer reported stronger-than-expected fiscal 2027 second-quarter earnings and revenue. Adjusted earnings per share came in at $1.16, well above the analyst consensus of $0.73, while revenue increased 19.5% year over year to $7.88 billion, compared with expectations of $7.03 billion. 

The earnings report also showed a 13.8% increase in used retail vehicle sales to 227,391 units, while comparable-store used unit sales rose 13%. However, gross profit per retail used vehicle declined by $111 to $2,105, reflecting pricing actions taken to support sales volumes. CarMax Auto Finance income increased 32.1% to $135.6 million, while the company said it remains on track for $200 million in exit-rate SG&A savings by the end of fiscal 2027. 

CarMax shares opened at $60.40, compared with the previous session’s close of approximately $56.76. The stock subsequently climbed to an intraday high of $63.67 and touched a low of $59.69. 

As of 10:55 a.m. ET, CarMax was trading at $60.90, up approximately 7.30% from the previous close. The intraday move indicates that the stock initially extended its gains after the earnings announcement before trading below its session high. 

The company also said it plans to resume share repurchases at a modest level during the third quarter, after no buybacks in the latest quarter. CarMax is scheduled to provide a broader strategic update on November 3.  

Uranium Energy Shares Fall Despite Revenue Beat as Quarterly Loss Widens 

Uranium Energy Corp. (NYSE American: UEC) reported a fourth-quarter fiscal 2026 adjusted loss of $0.07 per share, wider than the Zacks consensus estimate of a $0.04 loss. The company nevertheless exceeded revenue expectations, reporting $17.05 million in quarterly revenue, compared with the consensus estimate and zero revenue in the year-ago period. 

The results came alongside higher production and a weighted average realised uranium price of $93.13 per pound, according to the company. Uranium Energy also said it had expanded production across two mines during fiscal 2026. 

Despite the revenue beat and operational updates, Uranium Energy shares were trading lower during Tuesday’s session. The stock opened at $9.91, compared with the previous session’s close of approximately $10.01. It reached an intraday high of $9.94 and fell to a low of $8.98. 

As of 12:12 p.m. ET, UEC was trading at $9.10, down around 1.03% from the previous close. The stock’s intraday movement shows that the shares initially traded close to the previous session’s level before coming under pressure. 

Uranium Energy’s fiscal 2026 results therefore produced a mixed market response, with the revenue improvement and production expansion occurring alongside a larger-than-expected adjusted loss.  

One and One Green Technologies Shares Rise After Revenue and Profit Growth 

One and One Green Technologies (Nasdaq: YDDL) reported stronger first-half 2026 results, with revenue increasing 18.7% to $33.38 million and net income rising 17.4% to $4.49 million. Copper alloy revenue increased 38.9% to $25.71 million, helping offset lower aluminium revenue during an equipment upgrade. 

The company also reported a decline in gross margin to 21.73% from 25.32%, while total material shipped fell 10.4%. Management said aluminium processing resumed in July following the upgrade. 

YDDL shares were trading higher during Tuesday’s session following the results. The stock opened at $1.41, compared with the previous session’s close of approximately $1.40. It reached an intraday high of $1.44 and touched a low of $1.40. 

As of 11:53 a.m. ET, One and One Green Technologies shares were trading at $1.44, up approximately 2.86% from the previous close. The stock therefore remained near the upper end of its intraday range during the reported session. 

The company also reported stronger liquidity, with cash and cash equivalents of $2.71 million as of June 30, compared with $957,285 at the end of 2025. Management expects its upgraded processing lines and a new metals recovery line to support operations in the second half of 2026.

As of the latest available market data, Corning was trading at $157.35, up $5.76, or 3.80%, from the previous close. The stock therefore remained higher following news of the AT&T agreement. 

AT&T shares, meanwhile, were trading at $24.77, down 0.50% from the previous close of $24.90. AT&T reiterated the financial outlook and capital allocation plan provided with its second-quarter 2026 results, which incorporates the financial impact of the agreement.

Summit Therapeutics shares rose after AstraZeneca agreed to invest $2 billion in the drugmaker to collaborate on cancer treatments.

AstraZeneca shares also gained 1.6% to a two-month high in London trading, according to Reuters. Analysts cited the transaction as providing Summit with additional capital and clinical capabilities, while giving AstraZeneca access to a VEGF-bispecific cancer treatment approach. 

The companies also plan to conduct trials combining ivonescimab with multiple AstraZeneca cancer medicines. Financial and commercial outcomes will depend on the progress of these clinical programmes and the results of subsequent development activities.

The offering includes participation from new and existing institutional investors, including Eventide Asset Management, Janus Henderson Investors, Ridgeback Capital Investments and Wellington Management. J.P. Morgan is serving as the sole book-running manager.

VerifyMe has implemented a 1-for-10 reverse stock split of its common stock, effective at 12:01 a.m. ET on 29 September 2026. Shares began trading on Nasdaq on a post-split basis under the existing VRME ticker. Under the split, every 10 shares of issued and outstanding common stock were combined into one share.

The company said the split does not change each stockholder’s percentage ownership interest. Fractional shares resulting from the transaction are being rounded up to the nearest whole share. 

VerifyMe’s new CUSIP is 92346X305, while the par value remains $0.001 per share. Exercise prices and share amounts associated with outstanding warrants and equity awards have also been adjusted proportionately.

QumulusAI Shares Fall 13.34% Despite $240.9 Million Nvidia GPU Contracts 

QumulusAI shares fell in Tuesday’s trading despite the company announcing $240.9 million in new three-year contracts for Nvidia Blackwell B300 GPUs. The agreements cover more than 2,000 GPUs and expand relationships with two AI inference customers first established in July 2026. 

QumulusAI (NASDAQ: QMLS) was trading at $6.21 at around 12:54 p.m. ET on Tuesday, 29 September, down 13.34% from the previous close of approximately $7.17.

The shares had gained about 15% in premarket trading before reversing lower after the market opened. 

The larger agreement is valued at $211.9 million over three years and covers an AI inference platform deploying large language models and other applications. The customer’s total commitments to QumulusAI now exceed $283 million, with capacity targeted for delivery in early 2027. 

A second contract worth $29.1 million over three years is with a generative-AI inference platform serving developers and enterprises. Its total commitments to QumulusAI now exceed $61 million, with capacity expected in December 2026. 

Extension options could raise the combined potential value of the agreements to $401.6 million over five years. QumulusAI said the contracts allow it to deploy GPUs against signed customer commitments rather than forecasts.

Certain options and restricted stock awards would also be converted into cash, while options and warrants with exercise prices at or above $2.00 would be cancelled without consideration. 

Stockholders representing approximately 75% of the company’s voting power have approved the merger by written consent, satisfying one of the closing conditions.

Roze AI Shares Set to Begin Nasdaq Trading Under RZAI on 29 September 

Roze AI Inc. has announced that its common shares are expected to begin trading on the Nasdaq Capital Market under the ticker symbol RZAI on 29 September 2026. The commencement of trading is connected with the company’s direct listing of its common shares on Nasdaq. 

Based in Vancouver, British Columbia, Roze AI describes itself as a disaster-focused artificial intelligence company developing technologies designed to assess fire risks before an incident occurs and support preventive responses. 

Its technology includes Fire 4Cast, an AI-based fire-forecasting system designed to provide early fire-risk information for safety management. The company’s Disaster AI Platform (DAP) uses data collected through sensors installed in buildings, together with facility information, to calculate a Fire Risk Index. 

Fire 4Cast uses the resulting index to provide information intended to support preventive action. The system is designed to assess conditions at a facility and identify potential fire risks before an event occurs. 

Roze AI CEO Young Jin Cho said the Nasdaq listing marks the next stage for the company and acknowledged employees, shareholders and partners involved in developing its technology. According to the company, its team has spent years developing systems that combine sensor data and AI to assess fire risks. 

Following the expected start of trading, Roze AI said it plans to continue developing its technology and evaluate opportunities to introduce its systems to international markets. The company did not provide specific details on planned international launches or commercial timelines. 

Oura Postpones $2.2 Billion US IPO as Market Volatility Weighs on New Listings 

Smart-ring maker Oura has postponed its planned US initial public offering, becoming the latest high-profile company to delay a listing amid changing market conditions. The company had been expected to price the offering on 29 September and begin trading on Nasdaq on Wednesday. 

Oura and some existing investors had marketed 50 million shares at an indicated price range of $40 to $44 each. At the top of the range, the offering would have raised approximately $2.2 billion and valued Oura at about $15.6 billion on a fully diluted basis. 

Reuters reported that the IPO market has faced renewed uncertainty following higher bond yields, concerns about potential further Federal Reserve rate increases and investor scrutiny of spending on artificial intelligence infrastructure and elevated growth-company valuations. 

Oura’s offering had reportedly attracted orders equivalent to around four times the shares available. The company had planned to sell 13.5 million shares, while existing shareholders, including Forerunner Ventures and Lifeline Ventures, were expected to sell 36.5 million shares. 

Founded more than a decade ago in Finland, Oura has helped expand the smart-ring market with devices that track metrics including sleep, activity and heart-related measurements. The company said it is profitable and forecast fiscal 2026 revenue to increase 90% year-on-year. 

Oura CEO Tom Hale said the company intends to choose the timing of its IPO while continuing to pursue its business opportunities. The company also reported 5.7 million paid members following the launch of its Oura Ring 5. 

US-listed stocks recorded mixed movements on 29 September 2026 as investors responded to a range of company-specific developments. Carnival and SoundThinking advanced following stronger earnings and a proposed acquisition, respectively, while Corning gained after announcing a major fibre agreement with AT&T. Other stocks also moved sharply on contracts, partnerships, corporate actions and financial results. However, positive announcements did not always translate into gains, as seen with QumulusAI and Uranium Energy.
