Transaction Details

Crystal Clean's Board of Directors has unanimously approved the merger agreement and recommends that Crystal Clean shareholders vote in favor of the transaction.

The transaction is expected to close in the fourth quarter of 2023, subject to customary closing conditions, including approval by Crystal Clean shareholders and the expiration of the waiting period under the Hart-Scott-Rodino (HSR) Antitrust Improvements Act of 1976. Upon completion of the transaction, Crystal Clean will become a privately held company and shares of Crystal Clean common stock will no longer be listed on the Nasdaq Stock Exchange or trade in any other public market.

Fully committed debt financing in support of the transaction is being provided by Jefferies Finance LLC and Sumitomo Mitsui Banking Corporation. The merger is not subject to any financing condition.

Additionally, The Heritage Group and its affiliates, which collectively hold 26.70% of the Crystal Clean common shares, and Brian Recatto, who holds 3.23% of the Crystal Clean common shares, have each entered into a voting and support agreement with JFLCO pursuant to which each has committed to vote all of its Crystal Clean common shares in favor of the transaction.

The merger agreement provides for a "go-shop" provision under which Crystal Clean and its Board of Directors may actively solicit, receive, evaluate and potentially enter negotiations with parties that offer alternative proposals during a 35-day period following the execution date of the definitive agreement, expiring at 11:59 p.m. Eastern Time on August 23, 2023.
