Yes, worries about artificial intelligence can hurt Cisco's stock price, and they already have: Cisco Systems ($CSCO) closed at $101.61 on November 2, 2026, down 14.2% from $118.39 on October 9 and 21.8% below its June 4 closing high of $130.00. But the damage so far is sentiment, not the business. Cisco's fiscal 2026, which ended July 25, brought revenue of $63.3 billion, up 11.8%, and net income of $13.3 billion, up 30.3%, according to its annual report. The real test is the November 18 earnings report, because at roughly 30 times last year's earnings the stock now needs results, not reassurance. Our earlier look at Cisco's August earnings disappointment showed how quickly the market punishes a near miss.

What the AI warnings are actually about

The warnings hitting technology stocks this autumn are mostly about valuation and money flows, not about Cisco's products. In October, headlines compared today's AI leaders with the dot-com era. A Bank of America note reported on October 16 compared Nvidia, Micron and Broadcom with Cisco after the 2000 bust, and strategist Tom Lee pointed on October 24 to a setup he likened to Cisco's 1997 sell-off, while arguing the AI decline was nearing its end.

That history is why Cisco keeps appearing in the argument. It was the networking giant of the late 1990s, and its name has become shorthand for a great company bought at the wrong price. When investors start asking whether AI spending is a bubble, the comparison gets made, and Cisco's own shares get swept into the selling.

The fear has two parts. One is that companies spending heavily on AI data centers will slow that spending. The other is that the stocks already price in years of growth. Cisco is exposed to the first through its networking orders and to the second through its multiple.

How far Cisco has fallen, and against what

Cisco's drop has been steeper than the broad market's but in line with the technology-heavy Nasdaq-100 fund. All prices below are daily closes from Nasdaq.com data.

• Cisco: $110.29 on October 28 to $101.61 on November 2, down 7.9%.
• Invesco QQQ Trust ($QQQ): $725.61 to $681.09 over the same days, down 6.1%.
• SPDR S&P 500 ETF ($SPY): $772.31 to $752.10, down 2.6%.

Cisco is trading like an AI stock in a sell-off. Its numbers look more like those of a mature company with a growing AI business attached, and the gap between the two is the question investors have to answer.

What Cisco's fiscal 2026 numbers show

Cisco's annual report on Form 10-K, filed with the SEC on September 2, 2026, covers the year ended July 25, 2026:

• Revenue: $63.33 billion, up from $56.65 billion, a gain of 11.8%.
• Net income: $13.27 billion, up from $10.18 billion, a gain of 30.3%.
• Cash from operations: $14.18 billion. Capital spending was $1.41 billion, leaving about $12.77 billion of free cash flow.
• Diluted shares: 3.987 billion on average, down from 4.062 billion two years earlier.

Net income divided by diluted shares gives about $3.33 of earnings per share for the year. At the November 2 close of $101.61, that is a price of roughly 30.5 times trailing earnings: $101.61 ÷ $3.33 = 30.5. For comparison, Arista Networks ($ANET), a networking company closely tied to AI data centers, traded at about 53 times trailing earnings on the same day, according to Finnhub data.

So Cisco is not priced like the most aggressive AI names. It is also far from cheap for a company growing revenue in the low double digits. A multiple of 30 assumes the earnings growth continues.

Where the AI risk actually sits in Cisco's business

For Cisco, the AI trade cuts both ways. Data center builders buy its switches, routers and optics, so a slowdown in AI spending would hit orders. At the same time, a large share of Cisco's revenue comes from networking, security and software sold to businesses and governments, customers whose budgets do not rise and fall with one data center builder's plans.

That mix is the main reason Cisco is less exposed than a pure AI supplier. It is also why the stock rose with the AI trade: investors priced in a share of that boom. If the boom cools, Cisco can lose the premium without losing the business. That is the most likely form of damage from AI warnings: a lower multiple rather than a collapse in profits.

A quick way to see the sensitivity is to hold earnings steady and change the multiple.

• At 30.5 times $3.33: about $101.6, the November 2 close.
• At 25 times $3.33: about $83.3, or 18% lower.
• At 20 times $3.33: about $66.6, or 34% lower.

These are not forecasts. They show how much of the price rests on the market's willingness to pay for growth, and why a mood change can matter more than a quarter's numbers.

The November 18 report is the next test

Cisco is scheduled to report its first quarter of fiscal 2027 on November 18, 2026. Analysts' consensus, as compiled by Finnhub, calls for earnings of about $1.35 a share on revenue of about $18.48 billion.

Three things will matter more than the headline beat or miss:

• Orders from AI infrastructure customers. Any sign of slower data center spending would feed the very fear driving the sell-off.
• Guidance for the full year. A cut would confirm the warnings. A raise would test them.
• Margins. Higher component costs or price pressure would hit the earnings the multiple depends on.

Analyst sentiment going in is constructive: of 35 analysts tracked by Finnhub in November, 6 rate Cisco a strong buy, 17 a buy and 12 a hold, with none at sell. That consensus can change quickly after a report, as August showed.

What a cautious investor can do

For a conservative investor, the practical questions are position size and patience. Cisco's dividend and buybacks give it a cushion many AI stocks lack, which we work through in Cisco's dividend and buyback math. It does not make the shares immune to a sentiment-driven decline.

If you own Cisco, check how large it has become in your portfolio after the gains of the past year, and decide in advance what result on November 18 would change your view. If you are thinking of buying, the sell-off has lowered the multiple, but a reasonable approach is to wait for the report rather than guess at it.

FAQ

Why did Cisco stock fall in late October 2026?

Cisco fell with the wider sell-off in AI-linked technology shares, from $118.39 on October 9 to $101.61 on November 2. The decline followed the sector, not a change in Cisco's reported results.

Is Cisco an AI stock?

Partly. It sells networking equipment used in AI data centers, but a large share of its revenue comes from networking, security and software sold to businesses and governments. That makes it less exposed to an AI slowdown than suppliers who sell mostly to data center builders.

What is Cisco's P/E ratio now?

About 30.5 times trailing earnings at the November 2, 2026 close, using fiscal 2026 net income of $13.27 billion and 3.987 billion diluted shares.

When does Cisco report earnings next?

Cisco is scheduled to report its fiscal first quarter of 2027 on November 18, 2026.
