Assets Under Management Increase to a Record $21.7 Billion

Quarterly Net Inflows Total $1.1 Billion

Dallas, TX, April 29, 2015 – Westwood Holdings Group, Inc. (NYSE: WHG) today reported first quarter 2015 revenues of $29.6 million, a 14% increase compared to revenues of $25.9 million in the first quarter of 2014. First quarter 2015 net income and diluted earnings per share (“Diluted EPS”) were $5.6 million and $0.71, respectively, and included Woodway transaction costs, net of tax, of $0.5 million, which negatively impacted Diluted EPS by approximately $0.06. Net income and Diluted EPS were $5.6 million and $0.72, respectively, in the first quarter of 2014.

First quarter 2015 non-GAAP Economic Earnings and Non-GAAP Economic Earnings per share (“Economic EPS”) were $9.4 million and $1.20, respectively, and included Woodway transaction costs, net of tax, of $0.5 million, which negatively impacted Economic EPS by approximately $0.06. Non-GAAP Economic Earnings and Economic EPS were $9.2 million and $1.18, respectively, in the first quarter of 2014.

Highlights and significant items related to our first quarter 2015 results include:

• Revenues increased 14% to $29.6 million compared to the same period last year.

• Assets under management (“AUM”) reached a record level of $21.7 billion, with positive quarterly net inflows of $1.1 billion. Assets under advisement, for which we provide portfolio design and oversight, totaled $479 million.

• Net inflows into The Westwood Funds^® family of mutual funds totaled $456 million, representing an organic growth rate of over 12% from year-end. The Funds now account for approximately 20% of our overall AUM.

• Increased diversification in AUM by investment strategy, with 5 strategies individually exceeding $1 billion in AUM.

• Our Westwood Global and Emerging Markets team has surpassed $4.5 billion in AUM, less than three years since inception.

• Non-US clients represent approximately 20% of AUM, up from 3% in 2009.

On April 1, 2015, Westwood successfully completed the acquisition of Woodway Financial Advisors, which will substantially broaden the geographic reach of our Trust business. Woodway’s financial results will be consolidated into Westwood’s financial results beginning in the second quarter of 2015. Additionally, Woodway’s AUM will be included in Westwood’s AUM at that time.

Brian Casey, Westwood’s President & CEO, commented, “We are pleased with the continued strong demand for our Emerging Markets and Income Opportunity strategies, which drove significant net inflows for the quarter and helped push AUM to a record $21.7 billion. We are also very pleased with the successful closing of the Woodway acquisition and look forward to partnering with the Woodway team to provide exceptional service in the growing Houston market.”

Westwood’s Board of Directors today declared a quarterly cash dividend of $0.50 per common share, payable on July 1, 2015 to stockholders of record on June 12, 2015. At quarter-end, Westwood had $84 million in cash and investments, stockholders’ equity of $109 million, and no debt.

As supplemental information, we are providing non-GAAP performance measures that we refer to as Economic Earnings and Economic Earnings per share (or Economic EPS). We provide these measures in addition to, not as a substitute for, net income and earnings per share, which are reported on a GAAP basis. Management reviews Economic Earnings and Economic EPS to evaluate Westwood’s ongoing performance, allocate resources, and review dividend policy. We believe that these non-GAAP performance measures, while not substitutes for GAAP net income or earnings per share, are useful for both management and investors when evaluating Westwood’s underlying operating and financial performance and its available resources. We do not advocate that investors consider these non-GAAP measures without considering financial information prepared in accordance with GAAP.

We define Economic Earnings as net income plus non-cash equity-based compensation expense, amortization of intangible assets and deferred taxes related to goodwill. Although depreciation on fixed assets is a non-cash expense, we do not add it back when calculating Economic Earnings because depreciation charges represent an allocation of the decline in the value of the related assets that will ultimately require replacement. In addition, we do not adjust Economic Earnings for tax deductions related to restricted stock expense or amortization of intangible assets. Economic EPS represents Economic Earnings divided by diluted weighted average shares outstanding.
