Mirion Technologies Plummets 9.7% on $585M Nuclear Acquisition Amid Revised Guidance

Summary
• MIR shares plunge 9.7% to $22.205, erasing $2.4B of market cap
• $585M all-cash Paragon acquisition sparks liquidity concerns
• Organic revenue guidance cut to 4.5%-6.0% for FY2025
• Options volatility surges with 20+ contracts trading at 46%-74% IV

Mirion Technologies (MIR) is under pressure as a $585 million all-cash acquisition of Paragon Energy Solutions collides with revised revenue guidance. The stock has cratered from its $25.00 open to a 52-week low of $22.12, trading at 89% of its 200-day moving average. With 3.5 million shares changing hands—1.6x its 20-day average—the market is pricing in execution risks for the nuclear-focused industrial play.

Nuclear Expansion Sparks Liquidity Jitters
The 9.7% selloff follows Mirion's $585 million acquisition of Paragon Energy Solutions, a $150M revenue nuclear component supplier. While the deal promises $10M in synergies and 18x EBITDA multiple, the all-cash structure—funded by a Goldman Sachs bridge loan—has triggered liquidity concerns. Mirion's cash balance of $262.6M now faces pressure to fund the acquisition while maintaining operations. The company's revised 4.5%-6.0% organic growth guidance (down from 5%-7%) highlights softness in non-nuclear segments, compounding investor anxiety about capital allocation discipline.

Options Playbook: Capitalizing on Volatility and Technical Levels
• 200-day average: 18.11 (below) • RSI: 70.0 (overbought) • MACD: 0.90 (bullish) • Bollinger Bands: 19.31-25.39

Key technical levels suggest a volatile near-term path. The 200-day MA at $18.11 acts as critical support, while the 2025-10-17 options chain offers strategic entry points. Two standout options:

• MIR20251017P22.5 (Put): $22.50 strike, 46.8% IV, 0.149 gamma, 0.0397 theta, 228.57% price change
• MIR20251017C22.5 (Call): $22.50 strike, 46.8% IV, 0.149 gamma, 0.0397 theta, -60.78% price change

Under a 5% downside scenario to $21.10, the put option would yield $1.40/share (22.50-21.10) while the call would expire worthless. The put's 228.57% price change ratio indicates strong short-term volatility, amplified by its 0.149 gamma sensitivity to price swings. The call's -60.78% price change suggests aggressive bearish positioning, but its 0.149 gamma offers potential for rapid premium erosion if the stock stabilizes. Aggressive bulls may consider MIR20251017C22.5 into a bounce above $22.50, while bears should watch the 200-day MA for a potential short entry.

If you would like to change any assumption (e.g. add stop-loss / take-profit, hold for N days, or use intraday prices), just let me know and we can re-run.Please open the panel to see the detailed return curve, trade list, and performance statistics.

Critical Crossroads: Liquidity, Guidance, and Volatility
Mirion stands at a pivotal juncture as its nuclear expansion strategy faces immediate liquidity and execution tests. The 9.7% selloff has created a technical divergence between short-term bullish indicators and deteriorating fundamentals. Investors should monitor the $22.50 psychological level and the 200-day MA at $18.11 as critical decision points. With Caterpillar (CAT) down 0.3% as the sector leader, industrial machinery investors must weigh Mirion's unique nuclear exposure against broader sector weakness. A breakdown below $22.50 could trigger a cascade of put options activity, while a rebound above $25.00 might reinvigorate the acquisition thesis. Position sizing should reflect the high volatility and leverage ratios in the options chain.
