On November 26, 2018, People’s United Financial, Inc. (“People’s United”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with BSB Bancorp, Inc. (“BSB Bancorp”). The Merger Agreement provides that upon the terms and subject to the conditions set forth therein, BSB Bancorp will merge (the “Merger”) with and into People’s United, with People’s United as the surviving corporation. At the effective time of this Merger (the “Effective Time”), each outstanding share of BSB Bancorp common stock, par value $0.01 per share (“BSB Bancorp Common Stock”), will be converted into the right to receive 2.0 shares (the “Exchange Ratio”) of People’s United common stock, par value $0.01 per share (“People’s United Common Stock”).

At the Effective Time, each outstanding option granted by BSB Bancorp to purchase shares of BSB Bancorp Common Stock under the BSB Bancorp stock incentive plans (the “BSB Bancorp Options”), whether vested or unvested, will be cancelled and converted automatically into the right to receive a number of shares of People’s United Common Stock equal to the quotient of (i) the product of (A) the number of shares of BSB Bancorp Common Stock subject to such BSB Bancorp Option multiplied by (B) the excess, if any, of (1) the product of (x) the Exchange Ratio and (y) the People’s United Share Closing Price (as defined below) (the “Per Share Stock Consideration”) over (2) the exercise price per share of BSB Bancorp Common Stock subject to such BSB Bancorp Option, divided by (ii) the average closing price of the People’s United Common Stock for the five full trading days preceding the effective date of the Merger (the “People’s United Share Closing Price”), net of applicable tax withholdings.

Furthermore, at the Effective Time, each other outstanding equity-based award granted by BSB Bancorp under the BSB Bancorp stock incentive plans that is not a BSB Bancorp Stock Option (the “Other BSB Bancorp Equity Awards”), whether vested or unvested, will be cancelled and converted automatically into the right to receive a number of shares of People’s United Common Stock equal to the product of (i) the number of BSB Bancorp Common Stock subject to such Other BSB Bancorp Equity Award multiplied by (ii) the Exchange Ratio, net of applicable tax withholdings.

Following the Merger, Belmont Savings Bank, a Massachusetts-chartered savings bank and a wholly owned subsidiary of BSB Bancorp, will merge with and into People’s United Bank, National Association, a national banking association and a wholly owned subsidiary of People’s United, with People’s United Bank, National Association surviving.

The Merger Agreement contains customary representations and warranties from both People’s United and BSB Bancorp, and each party has agreed to customary covenants, including, among others, covenants relating to the conduct of BSB Bancorp’s and People’s United’s businesses during the interim period between the execution of the Merger Agreement and the Effective Time and, in the case of BSB Bancorp, its obligation to call a meeting of its stockholders to adopt the Merger Agreement, its obligation, subject to certain exceptions, to recommend that its stockholders approve the Merger Agreement and the Merger, and its non-solicitation obligations relating to alternative acquisition proposals.

The completion of the Merger is subject to customary conditions, including, among others, (1) the approval of the Merger by the holders of BSB Bancorp Common Stock, (2) authorization for listing on NASDAQ Global Select Market of the shares of People’s United Common Stock to be issued in the Merger, (3) the effectiveness of the registration statement on Form S-4 for the People’s United Common Stock to be issued in the Merger, (4) the absence of any order, injunction or other legal restraint preventing the completion of the Merger or making the consummation of the Merger illegal and (5) the receipt or waiver of required regulatory approvals, including the approval of the Board of Governors of the Federal Reserve System, the Office of the Comptroller of the Currency and the Massachusetts bank regulatory authorities. Each party’s obligation to complete the Merger is also subject to certain additional customary conditions, including (i) subject to certain exceptions, the accuracy of the representations and warranties of the other party, (ii) performance in all material respects by the other party of its obligations under the Merger Agreement and (iii) receipt by such party of an opinion from its counsel to the effect that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

The Merger Agreement provides certain termination rights for both People’s United and BSB Bancorp and further provides that a termination fee of $12.5 million will be payable by BSB Bancorp to People’s United upon termination of the Merger Agreement under certain circumstances.

The Merger Agreement was unanimously approved by the boards of both People’s United and BSB Bancorp.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached hereto as Exhibit 2.1 and is incorporated herein by reference. The representations, warranties and covenants of each party set forth in the Merger Agreement have been made only for purposes of, and were and are solely for the benefit of the parties to, the Merger Agreement, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between People’s United and BSB Bancorp instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Accordingly, the representations and warranties may not describe the actual state of affairs at the date they were made or at any other time, and investors should not rely on them as statements of fact. In addition, such representations and warranties (1) will not survive consummation of the Merger, unless otherwise specified therein, and (2) were made only as of the date of the Merger Agreement or such other date as is specified in the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding People’s United or BSB Bancorp, their respective affiliates or their respective businesses. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding People’s United, BSB Bancorp, their respective affiliates or their respective businesses, the Merger Agreement and the Merger that will be contained in, or incorporated by reference into, the Registration Statement on Form S-4 that will include a proxy statement of BSB Bancorp and a prospectus of People’s United, as well as in the Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and other filings that each of People’s United and BSB Bancorp make with the Securities and Exchange Commission (the “SEC”).
