AI Hardware Stocks Face Investor Scrutiny Amid Valuation Pressures
6/28/2026, 8:03:50 PM
Earnings Highlights and Stock Reactions
Cerebras Systems reported Q1 2026 revenue of $193 million, a 94 % year-over-year increase, and an operating loss of $3.5 million, far narrower than the $19.3 million loss a year earlier. Despite beating the $181 million consensus, the shares fell nearly 12 % after the release, driven by management’s guidance that margins would dip to 38-41 % (down from 47 % in Q1) as the company rents, rather than sells, systems to fulfill a $20 billion OpenAI contract.
Micron Technology posted fiscal-2026 third-quarter revenue of $41.5 billion, up 94 % YoY and above the $33.5 billion forecast. The company’s adjusted gross margin remained strong, and it highlighted multiyear strategic customer agreements that lock in roughly $100 billion of revenue.
In contrast, Nvidia and Broadcom shares have each slipped about 9 % over the past month, while Nokia’s stock surged 133 % to roughly $14 after a $1 billion AI-RAN partnership with Nvidia.
Background & Context
The AI boom has spurred unprecedented capital outlays for chips, memory, and networking equipment. Investors initially rewarded rapid revenue growth, but rising inflation, potential Federal Reserve rate hikes, and the high price-to-sales multiples of many AI hardware firms have prompted a reassessment of long-term profitability.
Data & Statistics
- Cerebras: Q1 2026 revenue $193 M (+94 % YoY); operating loss $3.5 M; adjusted gross-margin guidance 38-41 %.
- Micron: Q3 FY2026 revenue $41.5 B (+94 % YoY); P/S ratio 74 vs. sector average ~10.
- Nokia: Stock up 133 % to $14; partnership valued at $1 B.
- Nvidia market cap >$4.7 T; trailing P/E 86, forward P/E 36.
- Core inflation 3.4 % in May 2026, highest since Oct 2023.
Official Statements & Responses
Cerebras management said the temporary margin decline reflects a strategic shift to renting capacity for OpenAI, with an expectation to revert to higher-margin sales later in the year. Micron’s CEO Sanjay Mehrotra emphasized record-level investment in technology and multiyear strategic customer agreements to “significantly enhance the durability and predictability” of financial performance. Nokia’s partnership with Nvidia will embed ARC-Pro processors into its 5G gear, enabling AI inferencing at cell towers and supporting future 6G networks. European investors such as Eleva Capital’s Stephane Deo view AI-related capital spending by hyperscalers as “someone else’s sales,” while Calibrate Management’s Michela Ferrulli notes that “Nvidia gets the headlines, ABB gets the purchase orders.”
Criticism & Opposition
Analysts highlight the premium valuations of AI chip stocks—Cerebras trades at a trailing P/S of 74, and Nvidia’s forward P/E exceeds 30—as a risk if AI infrastructure spending slows. Concerns about inflation-driven rate hikes and the possibility that “hundreds of billions of dollars being poured into AI may never translate into profits” have led some investors to shift toward lower-priced, lower-risk assets.
Conflicting Reports & Gaps
While Micron and Nokia report robust revenue growth and bullish outlooks, Cerebras, Nvidia, and Broadcom experience share-price declines, reflecting divergent market expectations about the durability of AI spending. No consensus exists on the timing or magnitude of a potential slowdown.
