Smith Investment Company proposes restructuring
of holdings in A. O. Smith Corporation

Milwaukee, Wis. –– Smith Investment Company (SMIC - PK) announced today that it has made a proposal to restructure its holdings in A. O. Smith Corporation (AOS - NYSE). The proposed transaction would result in the shareholders of Smith Investment having direct ownership of the same number and type of A. O. Smith shares currently held by Smith Investment. Smith Investment’s common stock has been valued at a significant discount to the underlying value of the A. O. Smith shares held by Smith Investment. The proposed transaction is intended to allow Smith Investment’s shareholders to realize the underlying value of Smith Investment’s holdings in A. O. Smith and provide enhanced liquidity to Smith Investment’s shareholders.

Pursuant to the proposed transaction, Smith Investment would be merged with a newly formed subsidiary of A. O. Smith. In the merger, Smith Investment’s common stock would be exchanged for newly issued shares of A. O. Smith’s class A common stock and common stock. It is intended that this exchange would be non-taxable to the shareholders of Smith Investment. Because the total number and type of A. O. Smith shares issued in the proposed transaction would equal the number and type of A. O. Smith shares currently held by Smith Investment, there would be no net change to the number of outstanding A. O. Smith shares. Prior to the merger, Smith Investment intends to distribute in a taxable transaction substantially all of its assets (other than its holdings in A. O. Smith) to the shareholders of Smith Investment. The proposal also contemplates that, prior to the merger, substantially all of Smith Investment’s pre-closing liabilities would be discharged or assumed by the entity or entities in which Smith Investment’s distributed assets are held.

A special committee comprised of two independent directors from Smith Investment’s board of directors recommended the making of the proposal. The Smith Investment special committee was formed to consider possible transactions on behalf of the shareholders of Smith Investment other than certain members of the Smith family and trusts for the benefit of certain members of the Smith family. The Smith Investment special committee has engaged independent financial and legal advisors to assist it in completing its review. Smith Investment’s board of directors has agreed that it will not approve any transaction without the prior recommendation of the Smith Investment special committee.

Before recommending the proposal, the Smith Investment special committee consulted with certain Smith Investment shareholders holding in the aggregate a majority of Smith Investment’s common stock. These shareholders separately indicated to the Smith Investment special committee that they would support a transaction on substantially the terms proposed. These shareholders also separately indicated to the Smith Investment special committee that they would not support any alternative transaction that resulted in a sale of Smith Investment or otherwise eliminated or limited the dual class voting structure at A. O. Smith.

Smith Investment indicated that the proposal is preliminary, and remains subject to negotiation of definitive documentation and approval of the Smith Investment special committee and board of directors. The proposal also requires the approval of the A. O. Smith board of directors. A. O. Smith has not yet had an opportunity to respond to the proposal. There can be no assurance that the proposed transaction or any other transaction will result from the proposal. Except if required by applicable law, Smith Investment does not intend to comment further on the proposal unless and until a definitive agreement with respect to a proposed transaction has been reached.
