The estimates stopped moving a month ago
The skeptic case is that the easy math is behind it. Estimates for 2026 and 2027 sat unchanged through the 30 days to mid-October even as the stock rallied, and consensus models revenue growth of 42.1% this year slowing to 18.2% next 3. At 30.2 times forward earnings against an industry average of 22.1, the stock-research firm Zacks cut its own rating from Buy on October 5 to Sell on October 12 36.
Insiders sold $43.2 million of stock in 90 days, including a $25.8 million sale by executive chairman Brian Lane 1. Morgan Stanley's−0.76% — Morgan Stanley, down 0.76 percent today October survey of chief information officers sharpens the question: 43% of them have pulled some 2027 server spending into 2026, and more than 70% expect hardware budgets to flatten or decline by 2028 7. That survey polls hardware buyers, not construction clients, so it is adjacent evidence rather than proof.
Two readings settle it on Thursday
The bullish case still has Wall Street's backing: ten analysts rate the stock Moderate Buy with a mean target of $2,082.86, above the share price 1. Buy ratings have also come from a Seeking Alpha columnist and the Indonesian investing platform Pluang, and management said in July that hyperscaler demand showed no sign of slowdown 896.
Thursday turns on two readings: sequential backlog, up about 13% last quarter, and management's 2027 language, with same-store growth, which excludes acquisitions, guided to the mid-to-high 30s 3. Holders benefit if backlog is still accelerating and management defends 2027; anyone buying at 30 times earnings pays if bookings flatten 3. If the print disappoints, analysts will not raise those frozen 2027 estimates, and a 30-times multiple on halved growth compresses toward the industry's 22 3.
