Feature-Flagging Micron Alert Banners in JS Clients

From the public realtime drawing set:

Micron (MU) reports fiscal Q4 FY2026 on Wednesday, Sep 30, 2026 after the close, with the call at 4:30pm ET. Company guidance from June pointed to revenue of $50B ± $1B and non-GAAP EPS of $31 ± $1; street chatter into the print sits near $50.6–51.1B / $31.3–31.5. The prior quarter (June 24 print) did $41.5B. The tape will obsess over FY27 Q1 guide, HBM/DRAM tightness, and SK Hynix / Samsung read-across.

Flag design

• earnings.mu.banner — copy + deep link
• earnings.mu.burst-mode — tighter conflation windows
• Kill switch owned by on-call, not marketing

Client tips (BLACKJS mindset)

Avoid yield inside requestAnimationFrame when flipping banner DOM. Schedule banner mount on a macrotask after the current frame.

Test the flag flip on a paper watchlist first.

Not financial advice. Verify claims independently.
