Safety Insurance Group to Be Acquired by MAPFRE U.S.A. Corp. for $105 Per Share in All-Cash Merger

Merger Agreement Terms and Consideration Structure

Safety Insurance Group has agreed to merge with a subsidiary of MAPFRE U.S.A. Corp. under a definitive merger agreement executed on July 23, 2026. Pursuant to the transaction, each outstanding share of Company Common Stock will be converted into the right to receive $105.00 in cash, without interest, at the effective time of the merger. The disclosure states that the merger will result in Safety Insurance Group becoming a wholly-owned direct subsidiary of MAPFRE U.S.A. Corp., with the surviving corporation to be named as such after the merger closes.

The all-cash consideration of $105.00 per share applies to all outstanding shares of Company Common Stock, excluding dissenting shares, treasury stock held by the company, and shares owned by MAPFRE U.S.A. Corp., Splash Merger Sub, Inc., or any other parent subsidiary. The filing indicates that no interest will be paid on the merger consideration, and the consideration will be paid by the surviving corporation on the closing date of the transaction.

Board Approval and Shareholder Recommendation

The board of directors of Safety Insurance Group has unanimously determined that the merger agreement and related transactions are advisable and fair to the company and its stockholders. The filing indicates that the board has approved and declared the merger agreement advisable, and has resolved to recommend that the company's stockholders adopt the merger agreement and approve the underlying transactions. The board has further directed that the merger agreement be submitted to shareholders for their adoption and approval.

The unanimous board recommendation represents a significant endorsement of the transaction from the company's fiduciary leadership. The announcement states that the board determined the merger agreement and transactions are in the best interests of the company and its shareholders, supporting the submission of the deal to a stockholder vote for final approval before closing can occur.

Treatment of Restricted Stock Awards and Performance Share Awards

Under the merger agreement, all outstanding company restricted stock awards (Company RSAs) that are not vested as of immediately prior to the effective time will become fully vested upon the merger closing. Holders of these awards will receive cash consideration equal to the product of the $105.00 per share merger consideration multiplied by the number of shares subject to the cancelled RSA. The surviving corporation will pay this amount on the closing date, subject to required withholding deductions. Additionally, the company will pay each RSA holder an amount equal to all accrued and unpaid cash dividends that would have been paid on the underlying shares from the grant date through the effective time, less required withholding.

Performance share awards (Company PSAs) will also become fully vested upon closing, with any applicable performance conditions deemed satisfied at the performance levels specified in the company's disclosure schedules. Holders will receive cash consideration equal to the merger consideration multiplied by the applicable number of shares subject to the PSA. Like RSA holders, PSA holders will receive payment for accrued and unpaid cash dividends that would have been paid on the earned shares from the grant date through the effective time, subject to required withholding. The filing states that the surviving corporation and Parent will not assume any PSAs or substitute similar awards.

Conduct of Business Covenants During Interim Period

The merger agreement includes customary covenants governing the conduct of Safety Insurance Group's business during the interim period between the execution of the agreement and the completion of the merger. The company has agreed to conduct its business and that of its subsidiaries in the ordinary course in all material respects and to use commercially reasonable efforts to preserve its business organizations intact, maintain the availability of key employees, and preserve material business relationships and goodwill with third parties having significant dealings with the company or its subsidiaries.

The company is prohibited from engaging in certain specified actions during the interim period unless the actions are expressly required or permitted by the merger agreement, required by applicable law, disclosed in the disclosure schedules provided to Parent at execution, or consented to in writing in advance by Parent, such consent not to be unreasonably withheld, conditioned, or delayed. This covenant structure is designed to maintain the company's operational and financial stability pending merger closing.

Restrictions on Solicitation of Alternative Transactions

The merger agreement includes customary "no-shop" restrictions that generally prohibit Safety Insurance Group and its representatives from soliciting proposals relating to alternative acquisition transactions, participating in discussions or negotiations with third parties regarding such transactions, providing information to other parties with the intent to encourage or facilitate alternative acquisitions, or approving or entering into letters of intent or similar contracts relating to alternative transactions. These restrictions are subject to customary exceptions and compliance with specified procedures in the merger agreement.

The company has agreed to cease and cause the termination of any existing discussions or negotiations regarding alternative acquisition transactions. These provisions are designed to prevent the company from shopping the deal or entertaining competing offers once the agreement has been executed, thereby protecting MAPFRE U.S.A. Corp.'s investment in pursuing the transaction through regulatory approval and closing.

Regulatory Approvals and Closing Conditions

The completion of the merger is subject to customary closing conditions, including approval by holders of a majority of the voting power of the outstanding shares of Company Common Stock entitled to vote on the merger. The filing indicates that the transaction also requires expiration or termination of waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and approval by the Massachusetts Commissioner of Insurance. Additional governmental approvals are required as specified in the merger agreement, and the transaction is conditioned on the absence of legal restraints that would prevent closing.

The disclosure indicates that MAPFRE U.S.A. Corp. and Splash Merger Sub are subject to additional customary closing conditions beyond those applicable to the company. Both parent and the company have agreed to cooperate with each other and use reasonable best efforts to take or cause to be taken all actions necessary, proper, or advisable, subject to certain exceptions, to consummate the merger and obtain the regulatory approvals required for completion.

Representations, Warranties, and Cooperation Obligations

The merger agreement includes customary representations, warranties, and covenants from both the company and the parent regarding the transaction. These provisions establish factual and legal baselines for the transaction and define the obligations of each party during the period between signing and closing. The representations and warranties cover standard matters typically found in acquisition agreements of this nature and scope, and they are subject to the disclosure schedules provided by the company to Parent concurrently with execution of the merger agreement.

Both parties have committed to cooperate and use reasonable best efforts to take actions necessary to consummate the transaction. The merger agreement specifies that Parent and the company will work together to obtain required regulatory approvals, subject to certain specified exceptions. These cooperation obligations ensure that both sides are motivated to work toward a successful closing of the transaction once all conditions have been satisfied.

Strategic Significance and Market Position

The acquisition of Safety Insurance Group by MAPFRE U.S.A. Corp. represents a significant consolidation within the insurance industry. MAPFRE U.S.A. Corp. is acquiring Safety Insurance Group as a wholly-owned direct subsidiary, indicating a full integration of the company's operations into the parent's corporate structure. The all-cash merger consideration of $105.00 per share provides shareholders with a defined exit opportunity and eliminates uncertainty regarding the company's future as an independent public company.

Safety Insurance Group operates as an insurance provider, and the acquisition by MAPFRE U.S.A. Corp., part of the larger MAPFRE insurance group, suggests a strategic expansion of MAPFRE's U.S. insurance operations. The transaction is expected to close pending completion of regulatory review processes, including approval from the Massachusetts Commissioner of Insurance, which reflects the insurance sector's regulatory environment.

Path to Closing and Shareholder Approval

The transaction is expected to advance toward closing following the board's unanimous approval and recommendation. Shareholders of Safety Insurance Group will be required to vote to adopt the merger agreement and approve the underlying transaction. The filing indicates that approval by holders of a majority of the voting power of outstanding shares entitled to vote is a condition to closing. Once shareholder approval is obtained, the transaction will proceed to satisfy regulatory conditions, including Hart-Scott-Rodino antitrust clearance and approval from the Massachusetts Commissioner of Insurance.

The immediate share price impact was not clear from available public information at the time of the filing. Investors should monitor announcements regarding the scheduled shareholder meeting, where the merger will be voted upon, as well as regulatory filings and updates regarding the status of required approvals. The company and MAPFRE U.S.A. Corp. will need to navigate the regulatory approval process and satisfy all closing conditions before the transaction can be completed.

Employee Equity Considerations and Dividend Treatment

Employees and other equity holders at Safety Insurance Group with restricted stock awards and performance share awards will receive specified cash consideration as part of the merger. All outstanding RSAs and PSAs not vested prior to the effective time will become fully vested upon closing, eliminating the risk that equity holders will forfeit unvested awards. The treatment of equity awards is designed to ensure that existing employees and equity holders are made whole through full acceleration and cash settlement of their awards.

In addition to the merger consideration for RSAs and PSAs, the filing specifies that holders will receive payment for all accrued and unpaid cash dividends that would have been paid on the underlying shares had they been outstanding from grant date through the effective time. This dividend treatment is subject to required withholding deductions and represents a comprehensive approach to compensating equity holders for all economic benefits they would have received had the company remained independent through the expected vesting periods and dividend payment dates.
