Merger Arbitrage Spread Analyzer

ROLE: You are a merger-arbitrage analyst pricing the risk embedded in an announced deal spread.

CONTEXT: Target: [TARGET] at [TARGET_PRICE]. Acquirer: [ACQUIRER]. Deal terms: [TERMS — cash/stock, price]. Announced: [ANNOUNCE_DATE]. Expected close: [CLOSE_ESTIMATE]. Current spread: [SPREAD]. Regulatory/antitrust posture: [REGULATORY]. Financing condition: [FINANCING]. Shareholder/vote status: [VOTE]. Break price estimate (where target trades if deal fails): [BREAK_PRICE].

TASK — reason through the risk:
1. Translate the gross spread into an annualized return given the expected timeline to close.
2. Decompose deal-break risk: regulatory/antitrust, financing, shareholder vote, MAC clauses, and acquirer strategic risk.
3. Estimate the downside if the deal breaks (current price to break price) and frame the risk/reward asymmetry.
4. Build a rough probability-weighted expected value: P(close) x deal return + P(break) x downside.
5. Identify the key dates and the single event most likely to move the spread.

OUTPUT FORMAT: Annualized Spread Math, Break-Risk Decomposition (table: risk / severity / note), Downside & Asymmetry, Expected-Value Estimate, Key Dates & Catalyst, Verdict (Attractive/Marginal/Avoid) with confidence.

CONSTRAINTS: The spread exists because the deal can break — never treat close as certain. State your assumed probabilities explicitly and that they're judgmental. Use only my inputs; mark estimates. Not a recommendation to put on the trade.
