Safety Insurance sets Nov. 3 vote on $105-a-share MAPFRE buyout

What happened

Safety Insurance Group, Inc. filed a definitive proxy statement on Sept. 14, 2026, mailing it to stockholders of record as of Sept. 8, 2026 and setting a special meeting for Nov. 3, 2026 at 1:00 p.m. Eastern Time at the company's Boston headquarters.

The filing asks stockholders to adopt the Agreement and Plan of Merger dated July 23, 2026 among Safety, MAPFRE U.S.A. Corp. and Splash Merger Sub, Inc., a wholly owned subsidiary of MAPFRE U.S.A. Corp. Under the agreement, the merger subsidiary would merge into Safety, and Safety would survive as a wholly owned direct subsidiary of MAPFRE U.S.A. Corp.

If the merger closes, each share of Safety common stock would convert into $105.00 in cash, without interest, subject to applicable withholding, unless the holder properly exercises and does not withdraw appraisal rights. The proxy states that this equals a 44.8% premium to Safety's closing price on July 22, 2026, the day before the merger agreement was signed.

Safety's board unanimously approved the merger agreement, determined it advisable and fair to stockholders, and recommends stockholders vote for the merger proposal, a non-binding advisory compensation proposal and an adjournment proposal. Safety shares closed at $103.30 on Sept. 14, 2026, down 0.12%, according to the price data.

The three votes at the special meeting

Proposal 1 is the merger proposal itself: adopting the merger agreement and approving the transactions. It requires the affirmative vote of holders of a majority of Safety's outstanding common shares entitled to vote. The proxy states that failing to vote has the same effect as voting against the merger proposal, and that for shares held in street name, the broker or nominee cannot vote without instructions from the holder.

Proposal 2 is the compensation proposal: a non-binding, advisory vote on the compensation that will or may be paid or become payable to Safety's named executive officers based on or relating to the merger.

Proposal 3 is the adjournment proposal, which would let Safety adjourn the special meeting if needed to solicit additional proxies when there are insufficient votes to approve the merger proposal, or to ensure any necessary supplement or amendment to the proxy statement reaches stockholders.

What this means

A DEFM14A is a definitive proxy statement filed under Section 14(a) of the Securities Exchange Act of 1934. "DEFM" identifies it as definitive additional materials tied to a merger, and "14A" identifies it as a proxy filing. A proxy statement is the document a public company must send stockholders before a meeting at which they vote on the company's behalf. The word "definitive" distinguishes it from the earlier preliminary version: this is the final version being mailed, after the SEC review process. It is not a report of quarterly results or a notice of a share sale; it is the formal, legally required invitation and information package for a vote. Here, the specific obligation it satisfies is the requirement to give Safety's stockholders the details of the merger, the merger agreement, the board's recommendation and the voting procedures before they are asked to approve the deal.

Safety Insurance Group is a property and casualty insurer headquartered in Boston. Through its subsidiaries it sells private passenger automobile, commercial automobile, homeowners and other personal and commercial insurance, exclusively in Massachusetts, New Hampshire and Maine. Its stock trades on the Nasdaq Global Select Market under the ticker SAFT.

A cash merger works like this: the buyer forms a shell subsidiary, that subsidiary merges into the target company, and the target survives as a subsidiary. Stockholders of the target exchange their shares for the cash price. In this case MAPFRE U.S.A. Corp. is the buyer and Splash Merger Sub, Inc. is the shell. MAPFRE U.S.A. Corp. is itself described in the filing as a property and casualty insurer offering personal and commercial coverage in the United States and an indirect subsidiary of MAPFRE S.A., a multinational insurance group headquartered in Spain.

Because the consideration is all cash, a stockholder who votes yes is agreeing to sell at $105.00 per share and will not keep an ownership stake in the surviving company. The proxy notes that a stockholder who does not vote in favor of the merger proposal and who follows the procedures described under "Appraisal Rights" can instead ask a Delaware court to determine the fair value of the shares, provided a written demand is submitted before the vote and certain requirements are met.

The proxy also notes two related steps that normally accompany a deal like this: the section on "Delisting and Deregistration of Common Stock" describes the removal of Safety's shares from Nasdaq and the end of its SEC reporting obligation once the merger closes. This is the reverse of delisting debt securities at maturity — here, the common stock itself would cease to trade because the company would become privately held by its new parent.

The filing contains the background of the merger, the board's reasons for the deal, a fairness opinion from Jefferies LLC, financing arrangements, regulatory approval requirements and the full merger agreement as Annex A. A form of voting and support agreement with certain stockholders is attached as Annex B.

Completion is not automatic. The proxy states the merger cannot be completed unless the merger proposal wins a majority of the outstanding shares, and it identifies regulatory approvals as a condition. The filing does not forecast a closing date beyond a section titled "Anticipated Date of Completion of the Merger."
