What could move it
- An official announcement from either company would immediately settle the market; the absence of any such statement as the deadline approaches will gradually narrow the window for Yes resolution.
- Market movement will depend almost entirely on corporate announcements or credible reporting of merger discussions—structural or regulatory developments affecting either company could also influence positioning before the 2026 deadline.
