02What each reported, and what the analysts said the market wanted

ServiceNow said it beat the high end of its guidance on every top-line and profit measure: revenue rose 20.5% to US$4,106m and adjusted earnings were US$1.00 a share.1 CNBC reported revenue roughly in line with the US$4.10bn analysts expected (LSEG) and earnings two cents short of a US$1.02 forecast.10 Contracted revenue for the next twelve months (cRPO) grew 20.5% to US$13.65bn; ServiceNow guided its growth to 18.5% for the December quarter.1 Citi’s Tyler Radke told CNBC the market “wanted to see something a little bit sooner” from its AI investments, and that “you got to wait until next year to really see that inflection”.10

Fortinet grew revenue 20% to US$2.08bn and billings 29%, and raised its full-year revenue guidance.2 Product revenue grew 37% to US$765m, after 52% in the June quarter; service revenue grew about 13%, and Fortinet cut its full-year service guidance to US$5.150–5.170bn from US$5.180–5.220bn.23 Calcalist reported services at US$1.31bn against a US$1.33bn estimate, and quoted Wells Fargo on “the narrower-than-usual gap” between results and expectations: billings beat by about 2%, against 11% in the June quarter.11 TIKR reported that BofA cut the stock to Neutral from Buy over a “disappointing slowdown”.12

Intel grew revenue 21% to US$16.5bn, with Data Center and AI up 78% to US$7.3bn; its finance chief said revenue, gross margin and earnings per share “exceeded guidance”. It forecast US$15.0–16.0bn of revenue for the December quarter and adjusted earnings of US$0.25 a share, and David Zinsner said: “we see the PC slowdown continuing at least through the first half of next year”.5 Sharecast reported the forecast as “well below analyst expectations of $0.43 and $17.1bn”.13

Tenable grew 9.5% to US$276.4m, said it exceeded “every one of our guided metrics” and raised its full-year outlook.4 Its shares opened 6.1% lower on 29 October and closed 6.28% higher.9 We found no named analyst explaining the turn. Microsoft, Alphabet and Amazon are in our piece on cloud growth.

Tenable, the slowest grower of the seven, was the only one to close higher the session after its results

03What a falling share price changes for a buyer

The share price measures what investors expect next; the release shows the business today. ServiceNow generated US$822m of free cash flow in the quarter and holds US$29.7bn of contracted revenue not yet recognised.1 Fortinet generated US$865m of free cash flow and added US$1.2bn to its buyback authorisation.2 Intel generated US$5.1bn of cash from operations.5 None of that changed on 29 or 30 October.

What to watch. ServiceNow’s 18.5% cRPO guidance, Fortinet’s December-quarter revenue range of US$2.155–2.245bn and Intel’s US$15.0–16.0bn are the numbers the next results will be measured against, from late January.125 Whether the market’s fall on 30 October continues is a separate question that no one quoted here answered.
