Some year end ticker changes:
- CYBN — Rebranded + ticker changed + exchange move. Cybin transferred its U.S. listing from NYSE American to Nasdaq and began trading under HELP (doing business as Helus Pharma) on January 5, 2026; CYBN stopped trading as that symbol. ( Business Wire)
- CVAC — Acquired / going dark. CureVac was acquired into the BioNTech group; trading was suspended and CureVac requested Nasdaq delisting via Form 25 (company expects delisting to be effective January 16, 2026), so CVAC is being retired. ( curevac.gcs-web.com)
- WMT — Exchange move (ticker unchanged). Walmart transferred its listing from NYSE to Nasdaq Global Select Market; it started trading on Nasdaq on December 9, 2025 and kept ticker WMT. ( Walmart Inc.)
- SNV — Merged / delisted. Synovus completed its merger with Pinnacle; legacy SNV was delisted and the combined company trades on NYSE as PNFP starting January 2, 2026. ( pnfp.com)
- LEU — Uplisted (ticker unchanged). Centrus moved from NYSE American to the NYSE; trading on NYSE began December 4, 2025 and it kept ticker LEU. ( investors.centrusenergy.com)
- SPR — Acquired / delisted. Boeing completed its acquisition of Spirit AeroSystems on December 8, 2025; SPR ceased as a standalone listed company. ( Boeing Investors)
- QS — Exchange move (ticker unchanged). QuantumScape transferred from NYSE to Nasdaq; NYSE trading ended December 22, 2025 and Nasdaq trading began December 23, 2025, still as QS. ( SEC)
- SCS — Acquired / delisted. Steelcase was acquired by HNI and became a wholly owned subsidiary; NYSE filed to remove SCS from listing (and Steelcase terminated SEC registration), so SCS is gone. ( Stock Titan)
If your system keys symbols as EXCHANGE:TICKER, the “still-alive” ones likely broke because the exchange changed (WMT, QS, LEU).
