Taiwanese tech giant Foxconn on Thursday reported a record net profit for the third quarter, as the global buildout of data centres fuels demand for the AI servers needed to operate them.The world's largest electronics contract manufacturer has gone beyond making low-margin iPhones to producing AI servers for US tech titan Nvidia, as well as electric vehicles and robots.Its shares and those of other tech firms plunged last week on concerns that the Democrats' sweep of Congress in the US midterms would allow them to ramp up AI regulation and slow the data centre expansion.Foxconn partner Nvidia has also weighed on sentiment, with US media reporting the company's board is preparing to oust CEO Jensen Huang after revelations of his extramarital affairs, including with an alleged Chinese spy.Foxconn said net profit for July-September hit NT$77.5bn ($2.4bn), up 34% on-year.The result beat estimates of NT$70.3bn in a Bloomberg survey of analysts.Revenue for the three months was up 39 % at NT$7.7tn.Chief Financial Officer David Huang said Foxconn's "third-quarter revenue, operating income, net income, and earnings per share all reached record quarterly highs"."AI servers have become Foxconn's most important growth driver," Chairman Young Liu told a briefing.Looking ahead, he said "we remain very confident in next year's operations and believe growth will continue".But he warned of stubborn bottlenecks in the AI and consumer electronics supply chains, with overall demand "still expected to outpace supply heading into next year".That will mean "tight supply-demand conditions may persist for some time", he said.Foxconn has a longstanding partnership with Nvidia. In one of their collaborations, the companies are working to build an "AI factory supercomputer" in Taiwan.Governments and tech giants have been pouring huge sums into building data centres that can train and run AI tools such as chatbots, image generators and agents that can execute tasks.The buildout has turbocharged business for Foxconn — which makes the servers used in the centres — but any slowdown could potentially hurt the company's bottom line.In the short term, Liu said Foxconn did not "anticipate much of an impact" on demand for data centres and computing power as a result of the "midterm elections and certain industry shifts"."Over the long term, however, policy changes and some of the recent variables emerging in the market will require us to closely monitor just how significant the impact will be," he said.Data centres require large amounts of electricity, placing increased pressure on grids often still reliant on fossil fuels.In many cases, they also ramp up strain on water resources used to cool computing equipment.A backlash is growing worldwide against their environmental impacts, and there are also concerns over noise, pollution, their appearance and how many jobs the facilities actually create. TelefonicaSpanish telecoms giant Telefonica reported on Thursday a return to profit and a reduction of its debt in the year to September thanks notably to its core markets in Spain and Brazil.The group posted earnings of €464mn ($515mn) for the first nine months of the year, rebounding from steep losses of more than €1bn in the period last year.Revenue to September rose 2.8% to €24.8bn.Alongside Britain and Germany, Spain and Brazil are Telefonica's core markets after a strategic shift that saw it divest from Latin America in a bid to boost profitability.The company also announced on Thursday that it had cut its debt by 10.8% to €25.1bn by the end of September, its largest reduction since 2021.In 2025, Telefonica's losses ballooned to €4.32bn, mainly due to restructuring costs as it announced a plan to cut around 5,000 jobs and pull out of fiercely competitive Latin American markets.Telefonica chairman Marc Murtra said the "solid results" showed that the transformation plan "is proving its effectiveness and allows us to be more ambitious". BurberryBurberry returned to profit in its first half, the British luxury fashion label said Thursday, thanks to progress in its cost-cutting plan launched two years ago.Net profit stood at £6mn ($8mn) in the six months to the end of September, compared with a loss of £26mn a year earlier, Burberry said in an earnings statement.Revenue rose 6% to £1.1bn, and the company's shares jumped more than 7% in early deals on the London stock exchange.Burberry began a turnaround plan at the end of 2024 aiming to boost sales and cut costs as the global luxury sector suffers from weaker demand in China.Under chief executive Joshua Schulman, Burberry has refocused on its staple outerwear, including its famed trench coats, in a bid to improve its fortunes.Comparable retail sales grew 4% in the first half, lifted by sales in its key China market and in the Americas."The CEO is now over two years into his tenure and has injected a breath of fresh air into the brand's fortunes," said Richard Hunter, head of markets at Interactive Investor.He said the company's "strategy is gaining momentum as the brand increasingly resonates with the Gen Z cohort", while noting "the transformation is still in its early stages, and that of course the fashion industry can be a fickle business."China is a key market for the luxury sector, but as the country's post-pandemic recovery continues to struggle, consumption has flagged, sending jitters across the globe.AllianzGerman insurance giant Allianz on Wednesday raised its 2026 earnings outlook after reporting a record core profit for the first nine months of the year.The group raised the upper end of its target range for underlying profit to around €18.6bn ($20.6bn).Previously the insurer had guided for core profit of €17.4bn, plus or minus €1bn.In preliminary results, Allianz said it had booked a record core profit of €14.1bn in the first nine months of 2026, up around 8% from the previous year.The company will release full results for the first nine months of the year and the third quarter on Thursday. CoreWeaveCoreWeave beat Wall Street estimates for quarterly revenue on Tuesday, driven by strong demand for its cloud services, easing recent concerns around the durability of AI infrastructure demand amid its mounting debt load.The company reported revenue of $3.66bn for the third quarter ended September, up from $1.37bn a year earlier, compared with analysts' average estimate of $3.55bn, according to data compiled by LSEG.CoreWeave's stock has crashed more than 40% in the past month as the company emerged as the focal point of growing fears about a potential AI bubble, with investors fretting about heavy borrowing to fund purchases of chips, land and energy for AI data centers that generate little return until they are leased.The $27bn Nvidia-backed AI cloud company has never turned a profit, according to data compiled by LSEG, and had more than $50bn in debt as of June.Yields on CoreWeave's 2030 bonds are currently at about 15.2%, while its five-year credit-default swaps — a measure of perceived default risk — trade at 1,135 points.The selloff triggered a broader crisis of confidence in AI stocks, a sentiment amplified after the Democrats' sweeping win in the US midterms, as investors assess the potential for tighter regulation in America's data-center build-out.Recent earnings reports from hyperscalers also hinted at delays in data-center projects and a slower ramp in spending. Among CoreWeave's stacked roster of customers are Microsoft, Meta, OpenAI and Anthropic.CoreWeave operates about 52 data centers globally supported by advanced Nvidia chips and has a global active capacity of over 1.7 gigawatts — or enough power to supply more than 1.2mn US homes.Some analysts have said financing concerns about CoreWeave are overblown, citing its execution and financing track record. SiemensGerman engineering giant Siemens posted record annual profit on Thursday and said it saw growth ahead as the artificial intelligence boom sweeps up European companies in its supply chain.US tech giants such as Microsoft and Meta have together invested hundreds of billions of dollars in AI data centres, boosting the fortunes of companies like Siemens that make much of the electrical and cooling equipment needed to operate the sites.Swiss competitor ABB in October posted order growth of 40% for the three months to end-September, while France's Schneider Electric in the same month said sales growth over the period had beaten expectations.Reporting results for its fiscal year to end-September, Siemens said its core industrial profit, which strips out some effects such as last year's sale of motor-maker Innomotics, rose 13% to €13.3bn ($14.7bn) for the year.Siemens said it expected further growth in the current business year, guiding for sales growth of between nine and 11% across the company as well as broadly stable or higher profit margins at its two biggest divisions.In the longer term, Siemens said it was now targeting sales growth of between seven and 11% a year, up from six to nine, as well as annual earnings per share growth of at least 10 %, up from single-digit growth."Fiscal 2026 was an outstanding year for Siemens," CEO Roland Busch said in a statement. "We are providing an ambitious outlook for fiscal 2027 and are raising our group-level mid-term targets."For the fourth quarter, orders — an indicator of future sales — at Siemens' smart infrastructure business rose 40% to €8.67bn, helped by "numerous larger contract wins from data centre customers", Siemens said.Orders at Siemens' digital industries division, which makes software for engineering and automation, rose 16 % over the same period to €6.41bn.Under Busch, Siemens has pivoted towards higher-margin software products in recent years as part of its "Industrial AI" strategy.
