New York, Jan 27, 2026, 13:39 EST — Regular session
- Lumen shares jump roughly 7% following announcement of ISO 42001 certification
- Company says the certification applies to its AI management system deployed in internal operations
- Lumen’s earnings report on Feb. 3, released after the bell, is the next key event.
Shares of Lumen Technologies Inc (LUMN) jumped roughly 7% on Tuesday following the company’s announcement that it earned ISO 42001 certification for its artificial intelligence management system. The stock climbed 7.4% to $9.27, hitting a session high of $9.71 earlier.
The headline is crucial as companies face intensifying scrutiny over how they develop and manage AI systems, from boardrooms to regulators. For Lumen, it comes just before next week’s earnings, when investors will be looking for evidence that its AI strategy is driving more consistent demand.
Lumen announced it has earned ISO 42001 certification for its Artificial Intelligence Management System (AIMS), a standard designed to enforce controls on ethics, transparency, and risk management. “ISO 42001 certification reflects our unwavering commitment to responsible AI,” said Chief Legal Officer Mark Hacker. 1
The company clarified the certification covers its internal business processes. It added it plans to continue investing in “scalable, responsible AI” as it pushes forward with its roadmap.
For some traders, the announcement added weight to Lumen’s push to position itself as a network provider tailored for AI-driven workloads. Lumen offers fiber connectivity and related services, vying for enterprise network budgets against bigger U.S. carriers and niche operators.
Investors have been watching Lumen’s balance sheet moves closely. Earlier this month, the company announced that its Level 3 Financing unit would issue an extra $600 million in 8.5% senior notes maturing in 2036. The funds raised are earmarked for debt purchases connected to its ongoing tender offers. 2
Lumen is set to release its fourth-quarter and full-year earnings after the market closes on Feb. 3, with a conference call planned for 5 p.m. ET, the company announced. 3
Investors are focused on any updates about enterprise demand and whether AI-related traffic is driving sales growth. Cash flow and the company’s debt trajectory are also closely watched.
Lumen plans several public appearances that might offer more insight. The company confirmed it will participate in investor conferences throughout March, including those by Raymond James on March 2, Morgan Stanley on March 3, Deutsche Bank on March 10, and New Street on March 26. 4
Yet the trade can reverse quickly. ISO certification signals governance, not assured revenue, and any hint of sluggish customer spending or a weak outlook in next week’s earnings could quickly weigh on the stock.
