The narrow spread to the $18.50 deal price suggests the market expects closing. Key catalysts are the HSR waiting period expiration on July 30, 2026, and the shareholder vote on August 27, 2026. Any regulatory second request or shareholder litigation risk could widen the spread. Traders should monitor for HSR clearance and any competing bids or deal challenges.
