Forward-Looking Statements

This Current Report on Form 8-K only speaks at the date hereof and contains, and related discussions may contain, “forward- looking statements” within the meaning of U.S. federal securities laws. These statements include descriptions regarding the intent, belief, estimates, assumptions or current expectations of Aurora, Better or their respective officers with respect to the consolidated results of operations and financial condition, future events and plans of Aurora and Better. These forward-looking statements may be identified by a reference to a future period or by the use of forward-looking terminology. Forward-looking statements are typically identified by words such as “expect”, “believe”, “foresee”, “anticipate”, “intend”, “estimate”, “goal”, “strategy”, “plan”, “target” and “project” or conditional verbs such as “will”, “may”, “should”, “could” or “would” or the negative of these terms, although not all forward-looking statements contain these words. Forward-looking statements by their nature address matters that are, to different degrees, uncertain. Forward-looking statements are not historical facts, and are based upon management’s current expectations, beliefs, estimates and projections, and various assumptions, many of which are inherently uncertain and beyond Aurora’s and Better’s control. Such expectations, beliefs, estimates and projections are expressed in good faith, and management believes there is a reasonable basis for them. However, there can be no assurance that management’s expectations, beliefs, estimates and projections will be achieved, and actual results may differ materially from what is expressed in or indicated by the forward-looking statements. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by an investor as, a guarantee, an assurance, a prediction, or a definitive statement of fact or probability. Better is experiencing significant changes within the mortgage lending and servicing ecosystem which have magnified such uncertainties. In the past, actual results have differed from those suggested by forward-looking statements and this may happen again.

Important factors that could cause actual results to differ materially from those suggested by the forward-looking statements include, but are not limited to, Better’s performance, capabilities, strategy, and outlook; our expectations regarding the sustainability of Better’s rapid growth and its ability to manage its growth effectively; the demand for Better’s solutions and products and services, including the size of Better’s addressable market, market share, and market trends; Better’s ability to operate under and maintain Better’s business model; Better’s ability to develop and protect its brand; our expectations regarding financial performance including Better’s operational and financial targets; our estimates regarding expenses, future revenue, capital requirements and Better’s need for additional financing; the degree of business and financial risk associated with certain of Better’s loans; the high volatility in, or any inaccuracies in the estimates of, the value of Better’s assets; any changes in macro-economic conditions and in U.S. residential real estate market conditions, including changes in prevailing interest rates or monetary policies and the effects of the ongoing COVID-19 pandemic; Better’s expectations regarding the impact of the COVID-19 pandemic on Better’s business including on the volume of consumers refinancing existing loans, Better’s ability to produce loans, liquidity and employees; Better’s competitive position; Better’s ability to improve and expand its information technology and financial infrastructure, security and compliance requirements and operating and administrative systems; Better’s future investments in its technology and operations; Better’s intellectual property position, including its ability to maintain, protect and enhance Better’s intellectual property; the need to hire additional personnel and Better’s ability to attract and retain such personnel; Better’s ability to obtain additional capital and maintain cash flow or obtain adequate financing or financing on terms satisfactory to us; the effects of Better’s existing and future indebtedness on its liquidity and Better’s ability to operate our business; our expectations concerning relationships with third parties; Better’s plans to adopt the secured overnight financing rate (“SOFR”); the impact of laws and regulations and Better’s ability to comply with such laws and regulations including laws and regulations relating to fair lending, real estate brokerage matters, title and settlement services, consumer protection, advertising, tax, title insurance, loan production and servicing activities, data privacy, and anti-corruption; any changes in certain U.S. government-sponsored entities and government agencies, including Fannie Mae, Freddie Mac, Ginnie Mae and the FHA; Aurora’s expectations regarding the period during which we will qualify as an emerging growth company under the JOBS Act; the increased expenses associated with being a public company; and Better’s anticipated use of existing resources and the proceeds from the Business Combination.

There may be other risks not presently known to us or that we presently believe are not material that could also cause actual results to differ materially. Analysis and opinions contained in this communication may be based on assumptions that, if altered, can change the analysis or opinions expressed. In light of the significant uncertainties inherent in the forward-looking statements included in this communication, the inclusion of such forward-looking statements should not be regarded as a representation by us or any other person that the objectives and plans set forth in this report will be achieved, and you are cautioned not to place substantial weight or undue reliance on these forward-looking statements. These forward-looking statements speak only as of the date they are made and, Aurora and Better each disclaims any obligation, except as required by law, to update or revise forward-looking statements, whether as a result of new information, future events or otherwise.
