Keysight's Orders Jump 56% as AI Data Centers and Defense Spending Drive Demand

Keysight Technologies (NYSE: KEYS) just posted numbers that validate the AI infrastructure story with actual orders, not marketing promises.

The company's fiscal third-quarter 2026 orders hit $2.091 billion, up 56% year over year, according to TradingView. Revenue came in at $1.846 billion, up 36%. The Communications Solutions Group grew 43%. Electronic Industrial Solutions grew 21%.

Orders outpaced revenue by roughly $245 million, meaning demand is building faster than Keysight can ship product.

Demand Is Outrunning Supply

Chief Financial Officer Neil Dougherty told investors at a Truist investor conference that Keysight remains constrained more by supply than by demand, according to MarketBeat. Revenue booked outside the company's typical order-to-revenue window was approaching $100 million, Dougherty said, and the company is expanding manufacturing capacity, supplier agreements and component sourcing to catch up.

Wireline orders, the segment tied directly to AI data-center buildouts, more than doubled year over year. Commercial Communications revenue rose 56% to $1.006 billion, TradingView reported. Keysight finished the quarter with a record backlog.

Kailash Narayanan, senior vice president and president of Keysight's Communication Solutions Group, said the biggest AI-related contributors right now are speed transitions and system-level emulation, according to MarketBeat. Keysight is already seeing traction in 1.6-terabit networking technology while 3.2-terabit research is underway. Silicon photonics remains mostly an R&D opportunity the company expects to scale in coming years.

"Our customers' innovation cadence is increasing," Narayanan said, pointing to a rising number of product configurations as data rates climb from 100 gigabits per second toward 800.

Defense and Aerospace Growing Too

Aerospace, defense and government revenue rose 14% to $339 million, TradingView reported. Test and measurement gear for defense programs isn't glamorous, but it represents steady, government-funded demand tied to national security priorities rather than speculative tech spending.

Dougherty and other executives also pointed to 6G, semiconductor testing and software-defined vehicles as future growth drivers, according to Yahoo Finance. The company expects 6G-related acceleration in the first half of 2028 and says it plans to keep investing while targeting incremental margins of at least 40% once growth tops 5%.

On the automotive side, Keysight is working with the Centre for Assuring Autonomy at the University of York on methods to validate AI in software-defined vehicles and generate auditable safety evidence, according to Simply Wall St. That ties into Keysight's push toward recurring software revenue, though Simply Wall St noted automotive itself remains a "challenging" end market that management has flagged directly.

The Skeptic's Case

The strongest pushback isn't that Keysight's numbers are fake. AI infrastructure spending is a cycle, and cycles turn.

Simply Wall St laid out the concern plainly: tariffs, supply chain disruption and any cooling in AI infrastructure spending could pressure margins and expose Keysight to more volatile demand. A separate, more cautious analyst model cited by Simply Wall St puts 2029 revenue at roughly $9.2 billion and earnings at $2.7 billion, below the consensus figures of $10.4 billion in revenue and $2.8 billion in earnings. That represents a real disagreement among forecasters, not noise.

Hyperscalers and neoclouds pouring money into data centers today doesn't guarantee they keep pouring money in at the same pace in 2027 or 2028. Narayanan himself said hyperscalers represent a relatively small share of Keysight's direct revenue but drive several times that level of demand through their supplier ecosystems, according to MarketBeat. This means Keysight's fortunes are tied to decisions made several links up the AI supply chain, not decisions Keysight controls.

What Comes Next

Keysight guided fourth-quarter fiscal 2026 revenue to a range of $1.930 billion to $1.950 billion, according to TradingView. Whether that guidance holds, and whether the record backlog actually converts into shipped, billed revenue on schedule, is the next test.

Keysight's shares were up 1.07% as of Friday's close, according to Yahoo Finance. The company also continues expanding internationally, including in India, where Director of Marketing Sadaf Siddiqui told tele.net that Keysight is positioning itself as a design and test partner for India's 5G, 6G, AI and semiconductor ambitions, building on decades of legacy presence from HP and Agilent.

The open question for investors isn't whether AI demand is real. The orders prove that. It's whether Keysight can build enough supply fast enough to keep converting that backlog before the cycle, if it turns, catches up with them.
