Item 1.01. Entry into a Material Definitive Agreement.

On January 15, 2015 (the “Signing Date”), Westwood Holdings Group, Inc. (“Westwood”) entered into a definitive agreement to acquire Woodway Financial Advisors, A Trust Company (“Woodway”). The acquisition will occur pursuant to a Reorganization Agreement and Agreement and Plan of Merger (the “Merger Agreement”), by and among Westwood, Westwood Trust, a Texas trust association wholly-owned by Westwood (“Westwood Trust”), Woodway and shareholders of Woodway. Woodway is a private wealth and trust company based in Houston, Texas and manages over $1.6 billion in private wealth client assets and has 27 employees. Based on information provided by Woodway, its fiscal 2014 revenues and earnings before income taxes, depreciation and amortization are estimated to be approximately $10.4 million and $5.2 million, respectively.

Woodway will merge with Westwood Trust, with Westwood Trust being the surviving entity (the “Merger”). Each membership interest in Woodway will be converted into the right to receive the merger consideration from Westwood. The total merger consideration is (i) $32 million, subject to adjustment for the amount of Woodway’s working capital at closing, and subject to reduction for Woodway’s outstanding indebtedness and unpaid transaction expenses as of closing, and (ii) an Earn-Out Amount equal to annualized revenue from the post-closing business of Woodway for the twelve month period following the effective time of the Merger (the “Earn-Out Period”), adjusted for clients or accounts that have terminated, and capped at $15 million (the “Earn-Out Amount”).

Approximately 73% of the total merger consideration will be paid in cash. The remaining 27% will be paid through the issuance of shares of Westwood common stock. The number of shares of Westwood common stock comprising the stock portion of the initial merger consideration payable at closing will be determined by dividing the dollar amount of the portion of such payment consisting of Westwood common stock by the average closing price of Westwood common stock over the 15 business days prior to the Signing Date. The number of shares of Westwood common stock comprising the stock portion of the Earn-Out Amount will be determined by dividing the dollar amount of such payment consisting of Westwood common stock by the average closing price of Westwood common stock for the last 30 days of the Earn-Out Period.

The shares of Westwood common stock issued pursuant to the Merger will be issued only to “accredited investors” within the meaning of Regulation D promulgated under the Securities Act of 1933 (the “Securities Act”). No public offering of securities is contemplated.

The Merger Agreement contains customary representations, warranties and covenants by the parties, as well as indemnification rights of both parties. Subject to customary loss baskets and caps, breach of the representations, warranties or covenants of Woodway or the Woodway Shareholders may be recouped or set off against the Earn-Out Amount.

Each of the board of directors of Westwood, Westwood Trust and Woodway have approved the Merger and Merger Agreement. The Merger is subject to approval by the shareholders of Woodway. Woodway shareholders holding greater than 99% of the voting capital stock of Woodway have executed irrevocable proxies in favor of the Merger. The Merger is subject to the approval of the Texas Department of Banking.

The completion of the Merger is subject to customary closing conditions, including the absence of any material adverse effect on the business and operations of Woodway.

The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto, and is incorporated into this report by reference. The Merger Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about Westwood or Woodway. In particular, the assertions embodied in the representations and warranties contained in the Merger Agreement are qualified by information in a confidential disclosure schedule provided by Woodway to Westwood in connection with the signing of the Merger Agreement (the “Disclosure Schedule”). The Disclosure Schedule contains information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Merger Agreement.

- 2 -

Moreover, certain representations and warranties in the Merger Agreement were used for the purpose of allocating risk between Westwood and Woodway rather than establishing matters as facts. Accordingly, you should not rely on the representations and warranties in the Merger Agreement as characterizations of the actual state of any facts about Westwood or Woodway.

Item 3.02. Unregistered Sales of Equity Securities.

As described in Item 1.01 above, Westwood has entered into the Merger Agreement pursuant to which Westwood will issue shares of its common stock as part of the consideration upon consummation of the Merger. The number of shares of Westwood common stock comprising the stock portion of the initial merger consideration payable at closing will be determined by dividing the dollar amount of the portion of such payment consisting of Westwood common stock by the average closing price of Westwood common stock over the 15 business days prior to the Signing Date. The number of shares of Westwood common stock comprising the stock portion of the Earn-Out Amount will be determined by dividing the dollar amount of the portion of such payment consisting of Westwood common stock by the average closing price of Westwood Common Stock for the last 30 days of the Earn-Out Period.

The issuance and sale of the shares of Westwood common stock is exempt from registration under Section 4(a)(2) of the Securities Act because the transaction does not involve a public offering. Westwood has not engaged in general solicitation or advertising with regard to the issuance and sale of the Westwood common stock to be issued in the Merger.
