The merger provides a clear value creation path through substantial cost synergies and vertical integration. Traders should monitor regulatory developments (antitrust reviews in US, EU, and other jurisdictions) and shareholder vote timelines. The long close timeline (first half 2027) introduces execution risk; any delays or regulatory pushback could pressure the spread. Watch for potential competing bids given the strategic value of the combined assets.
