Keysight's orders grew 56% on the AI buildout, and its stock still fell 8.7% in a week

Keysight▼−2.19% — Keysight, down 2.19 percent today Technologies used Open Compute Project week, the open-hardware community's annual summit in San Jose, to launch four validation platforms in three days↗, machines built to prove the next doubling of AI network speed before anyone deploys it ¹²⁶⁷. NVIDIA▼−0.38% — NVIDIA, down 0.38 percent today, the AI chipmaker, plus Credo▼−3.11% — Credo, down 3.11 percent today, which sells cables that link AI racks, and Synopsys▼−4.07% — Synopsys, down 4.07 percent today, a chip-design software and silicon-IP company, put their names on the gear ¹²⁶. The market's answer landed on October 15, when the shares fell 4.3% to $342.08, an 8.7% drop for the week ⁴.

The machines that grade the fabric

The centerpiece, AresONE Plus 1600GE, packs eight OSFP1600 ports, a pluggable-module standard carrying 1.6 terabits a second, into a 2U chassis, about nine centimetres of rack height, driving 12.8 terabits of line-rate traffic, which Keysight calls an industry first ¹⁷. NVIDIA builds the network gear; Keysight builds the machines that prove the gear works before it ships. Gilad Shainer, NVIDIA's senior vice president of networking, said Spectrum-X AI fabrics get tested on Keysight platforms "before deployment, reducing time to market" ¹.

Credo validates its active electrical cables on FITS-16CH, an error tester with 16 channels in each direction, twice the density of the old box ². Synopsys ran its PCIe 7.0 designs, the rack-scale interconnect that doubles to 128 gigatransfers per second, through Keysight's new protocol tester ⁶.

The orders already arrived

Fiscal third-quarter revenue, for the period ended July 31, was $1.846 billion, up 36.5% from a year earlier, on filings ⁸⁹. Orders grew 56% year over year, management said on the August 18 earnings call↗ ⁵. Earnings of $3.07 a share beat the $2.48 consensus ⁸. Revenue has risen every quarter since mid-2024, from $1.22 billion to $1.85 billion ⁹.

Priced like a winner, sold by insiders

The case for the stock is orders compounding faster than revenue; the case against is a price that already assumes they keep compounding. Keysight trades at 47.1 times trailing earnings against a five-year median of 30.8, after a 68% run this year, and GuruFocus↗, a stock-analysis site, puts its model's fair value at $225.99, with the shares 51% above it ⁴. Insiders sold $33.4 million of stock over 12 months and bought none; the same screen still scores the company's financial health 84 out of 100 ⁴.

Also on October 15, Keysight filed the annual UK takeover-code confirmation↗ that it kept the post-offer promises made for Spirent Communications, the London-listed company its cash offer absorbed when the scheme became effective on October 15, 2025 ³.

What November 23 decides

Management guided fourth-quarter earnings to $3.34 to $3.40 a share↗, on a full year near $11.46 ⁸. Results land November 23 ⁵. Watch whether orders keep compounding near 56% year over year, and whether that guidance holds once the fiscal fourth quarter is booked ⁵⁸. The comparison stops being easy from there: the quarter that ended in January was already growing 23% ⁹.
