What Happened?
Arista Networks (ANET) closed at $206.55 on September 25, 2026, 1.88% below its record close of $210.50 on August 12. At Citi’s Global TMT Conference on September 10, CFO Chantelle Breithaupt was asked how far along the current deferred-revenue cycle is. She said the cloud cycle “was about 3 years” and added, “We’re in, I would say, going into year 2.5 to 3 on AI proper from a materiality perspective.”
Arista joined the S&P 100 on September 21 in a rebalance that also added three other companies, and the stock rose 3.05% that session, according to TradingKey. Breithaupt argued “this cycle could be longer.” Her remarks, archived in Arista’s investor relations materials, tie that case to products outside 2026 guidance.
Scale-Up Ethernet Is Out of 2026 Guidance, With Revenue Expected in 2028
Breithaupt said “we have 0 in our guidance and 0 revenue for Arista for scale up in ’26,” and “’28 is when we get the revenue there.” Tyson Lamoreaux, Senior Vice President of Cloud and AI Networking, put early XPO deployments in the second half of 2027, “really ramping in ’28,” with a co-packaged optics ramp probably 12 months behind that. These are management plans, not booked orders.
Enterprise could stretch the cycle further. Lamoreaux cited “Mythos and Glasswing,” Anthropic’s vulnerability-hunting AI model and security initiative, and “an ever-increasing rate of security vulnerability discovery.” Breithaupt said enterprises new to Arista have approached it “ahead of their refresh” so they only have to patch once, and she put campus revenue on a path from $800 million in 2025 to $1.25 billion in 2026.
Arista also plans to revise its $105 billion market-size estimate from October 2025, “hopefully” later in 2026. Since June 30, consensus revenue for 2027 has risen around 13% to about $16.2 billion, and the 2028 estimate has climbed around 14% to about $19.8 billion.

Q2 Free Cash Flow Fell Even as Revenue Rose 37.69%
Q2 free cash flow of $1,053.3 million missed the Street by 17.15% and fell 10.44% year over year, even as revenue rose 37.69%. It followed $1,639.0 million in Q1, so one quarter is not yet a trend. Reported sales can also lag the cycle, since Breithaupt said “some of these deployments can take 18 months to 24 months until we hit the acceptance criteria.”
Arista’s one price increase earlier in 2026 targeted memory-heavy products to “at least keep us margin neutral,” Breithaupt said, adding, “We’re not looking to accrete margin.” She said fab capacity and memory look sorted through 2027, while parts such as PCBs and capacitors remain “whack-a-mole.”
At an NTM P/E ratio of 44.47x, against 20.73x for Cisco (CSCO) and 34.36x for Ciena (CIEN), the stock already prices in much of a longer cycle. CEO Jayshree Ullal also filed a Form 144 on September 25, giving notice of a proposed sale of 62,622 shares valued at about $13.2 million. The notice does not confirm a completed sale.

The TIKR mid case is a scenario built on stated assumptions. It reaches around $428 by December 31, 2030, a total return near 107%, or about 19% a year over 4.3 years. Over its 2025-to-2035 forecast window, it assumes revenue growth around 19% a year and a net margin near 41%, close to the 41.5% Arista earned over the past year, so margins must hold rather than expand.
The two growth drivers are scale-up Ethernet from 2028 and security-driven enterprise refreshes. The primary risk is timing: a cycle that peaks before scale-up revenue arrives would make the model’s roughly flat P/E assumption hard to defend from today’s premium.
Growth has room to beat the mid case, since ~19% sits below Street consensus for each year from 2026 through 2029, though the 2029 estimate rests on four analysts. A cycle that ends on the cloud cycle’s roughly three-year schedule would cut growth and the multiple at once.
Conclusion
Arista’s third-quarter report, expected in early November, is the next test. Management guided to about $3.3 billion in revenue and a 48% to 49% non-GAAP operating margin. Free cash flow back above Q2’s $1,053.3 million would support a cycle running past year three. A fourth-quarter outlook below the Street’s roughly $3.6 billion would point to one closer to the cloud cycle’s length.
