Micron's $100 Billion Backlog and Index Makeover Cement a New Valuation Regime

Micron's FTSE Russell reclassification to growth index underscores record revenue, 84.9% gross margin, and $100B in long-term HBM contracts linked to AI infrastructure demand.

The reclassification of Micron Technology from a value stock to a pure growth name by FTSE Russell, effective June 29, is more than a bureaucratic re-labelling. It caps a quarter in which the memory-chip maker delivered financial results that stretch the boundaries of even the most aggressive AI-infrastructure narratives, and comes with a multi-year customer contract pipeline that Wall Street is only beginning to price in.

Micron reported revenue of $41.46 billion for its third fiscal quarter, a more than fourfold jump from the $9.30 billion recorded a year earlier. Operating cash flow surged to $25.39 billion from $4.61 billion, while GAAP net income landed at $28.24 billion, or $24.67 per diluted share. The gross margin hit 84.9%, a level that would have been unthinkable in the memory-chip industry just a few years ago. For the current period, management projects revenue of roughly $50 billion and gross margins rising to 86%.

The numbers reflect an unprecedented demand cycle for high-bandwidth memory (HBM), the specialised chips used in artificial-intelligence processors. Micron’s entire HBM allocation for 2026 is already spoken for at fixed prices, and orders for the HBM3E and HBM4 generations stretch into 2027 and 2028. The cloud segment alone contributed $13.8 billion in revenue, up 78% sequentially. CEO Sanjay Mehrotra is ploughing capital into production capacity to stay ahead of rivals snapping at Micron’s heels.

Perhaps the most telling evidence of Micron’s structural shift lies in its customer contract strategy. JPMorgan analyst Harlan Sur, who raised his price target on the stock, noted that Micron has signed 16 long-term supply agreements, up from a single five-year deal. These contracts specify price floors and cumulative minimum revenue of approximately $100 billion. The implied gross margins, according to management, exceed the peak margins of any previous memory cycle. Such commitments effectively insulate Micron from the kind of pricing volatility that once defined the sector.

The FTSE Russell reclassification locks in a new investor base. Some $12.2 trillion in assets tracks the Russell US indices, and when a company moves from value to growth, index-tied fund flows automatically follow. Micron and SanDisk were the most prominent additions to the growth segment in the annual reconstitution. The shift is especially significant because FTSE Russell has moved to a semi-annual rebalancing schedule, with the next review in December. Micron must sustain its growth metrics to hold the designation.

The stock trades at around €1,008.60, up 0.87% on the day, and has surged roughly 275% since the start of the year. The 52-week high of €1,103.80, set on June 25, sits about 9% above current levels. The relative strength index of 60.6 suggests the shares are not yet overbought, despite the rally. Meanwhile, the distance to the 200-day moving average exceeds 165%, underscoring how rapidly the company has outrun its former valuation range.

Micron ended the quarter with $30.2 billion in cash and marketable securities. It will pay a quarterly dividend of $0.15 per share on July 21. With a 16-contract revenue backlog, an index upgrade that forces fresh buying, and a product cycle that is pre-sold for years, the company now faces the challenge of delivering on expectations that have already redefined the memory industry’s financial architecture.
