Certain matters discussed within or in connection with these materials may contain “forward-looking statements” as defined in federal securities laws, which are subject to risks and uncertainties and are based on Texas Capital’s current estimates or expectations of future events or future results. These statements are not historical in nature and can generally be identified by such words as “believe,” “expect,” “estimate,” “anticipate,” “plan,” “may,” “will,” “intend” and similar expressions. A number of factors, many of which are beyond our control, could cause actual results to differ materially from future results expressed or implied by such forward-looking statements. These risks and uncertainties include, but are not limited to, the credit quality of our loan portfolio, general economic conditions in the United States and in our markets, including the continued impact on our customers from volatility in oil and gas prices, expectations regarding rates of default and loan losses, volatility in the mortgage industry, our business strategies and our expectations about future financial performance, future growth and earnings, the appropriateness of our allowance for loan losses and provision for credit losses, the impact of changing regulatory requirements and legislative changes on our business, increased competition, interest rate risk, new lines of business, new product or service offerings and new technologies. These and other factors that could cause results to differ materially from those described in the forward-looking statements, as well as a discussion of the risks and uncertainties that may affect our business, can be found in our Annual Report on Form 10-K and in other filings we make with the Securities and Exchange Commission.

2019 Outlook Business 2019 Outlook v. 2018 Results Comments & Changes since April 17, Driver 2019 Decreased from mid to high-single digit Average LHI Mid-single digit percent growth percent growth Average LHI – Mortgage Low to mid-twenties percent growth Increased from high-teens percent growth Finance Loans held for $2.5 billion average - sale (MCA) Average Increased from high-single digit percent Low-double digit percent growth Deposits growth Net Revenue High-single digit percent growth - Net Interest 3.35% to 3.45% Decreased from 3.60% to 3.70% Margin Provision Mid to high $80 million level - Expense Increased from mid-single digit percent NIE Mid to high-single digit percent growth growth Efficiency Ratio Low-50s - 12

Long-term Outlook Financial Goals ROA > 1.3% ROCE > 15% Efficiency Ratio < 50% Key Assumptions • Continuation of current economic conditions, allowing the Bank to capitalize on Inflection Point initiatives of growing higher return businesses and deepening client relationships • Despite more potential volatility in provision, NCOs remain 20-25 bps of average total LHI • Mortgage Finance brand strengthens and relationships expand, allowing the Bank to focus on serving high-value clients and maximizing returns • Lower-cost, lower-beta deposit verticals achieve growth and ROI targets and mitigate any earnings impacts caused by rate volatility • Product enhancements and expanded offerings improve non-interest income contribution to total revenue, even amidst ex- liquidity NIM expansion • Internal investments yield efficiency benefits and allow Bank to maintain moderate overhead growth over the horizon • Bank remains committed to efficient use of shareholder capital and maintaining liquidity at appropriate levels 13

Closing Comments • Focus on delivering premier client experience to our clients and being deliberate in our prospecting of new client relationships • Slight decrease in LHI in Q2-2019, primarily from expected runoff in leveraged lending portfolio • Taking advantage of outsized growth in mortgage finance in seasonally strong quarter with additional volumes from lower long-term rates; Q3-2019 volumes expected to be equally as strong • Seeing progress with deposit initiatives as well as growth in our existing client base • Confirming annual guidance on loan loss provisioning despite Q2-2019 provisions primarily related to energy, and not leveraged portfolio • Targeted approach in slowing pace of operating expenses is working, as we continue to be opportunistic with hiring and improving efficiencies through technology and better processes 14
