These statements are based on management’s current expectations, but are subject to risks and uncertainties, many of which are outside of our control, and could cause future events or results to materially differ from those stated or implied in the forward-looking statements, including: (1) UWMC’s ability to successfully implement strategic decisions and product launches; (2) UWMC’s dependence on macroeconomic and U.S. residential real estate market conditions, including changes in U.S. monetary policies that affect interest rates and inflation; (3) UWMC’s reliance on its warehouse and MSR facilities and the risk of a decrease in the value of the collateral underlying certain of its facilities causing an unanticipated margin call; (4) UWMC’s ability to sell loans in the secondary market; (5) UWMC’s dependence on the government-sponsored entities such as Fannie Mae and Freddie Mac; (6) changes in the GSEs, FHA, USDA and VA guidelines or GSE and Ginnie Mae guarantees; (7) our ability to comply with all rules and regulations in connection with the launch of our internal servicing and the new risks that may be presented as a result of the transition; (8) UWMC’s dependence on Independent Mortgage Advisors to originate mortgage loans; (9) UWMC’s ability to successfully implement strategies to increase cash flow and reduce preferred; (10) UWMC’s inability to continue to grow, or to effectively manage the growth of its loan origination volume; (11) UWMC’s ability to successfully implement its new hedging policy; (12) UWMC’s ability to continue to comply with the complex state and federal laws, regulations or practices applicable to mortgage loan origination and servicing in general; and (13) other risks and uncertainties indicated from time to time in our filings with the Securities and Exchange Commission including those under “Risk Factors” therein. UWMC further wishes to caution readers that certain important factors may have affected and could in the future affect UWMC’s results and could cause actual results for subsequent periods to differ materially from those expressed in any forward-looking statement made by or on behalf of UWM. The information provided in this presentation is provided as of the date hereof, and UWMC undertakes no obligation to update such information or forward-looking statements to reflect events or circumstances after the date of this presentation. This presentation includes certain non-GAAP financial measures, including Adjusted EBITDA, non-funding debt and non-funding debt to equity ratio. We define Adjusted EBITDA as earnings before interest expense on non-funding debt, provision for income taxes, depreciation and amortization, adjusted to exclude stock-based compensation expense, the change in fair value of MSRs due to valuation inputs or assumptions, gains or losses on other interest rate derivatives, the impact of non-cash deferred compensation expense, the change in fair value of the Public and Private Warrants, the non-cash income/expense impact of the change in the Tax Receivable Agreement liability, the change in fair value of retained investment securities, and acquisition related expenses (net of recoveries) as we believe these adjustments are not indicative of our performance or results of operations. Adjusted EBITDA includes interest expense on funding facilities, which are recorded as a component of interest expense, as these expenses are a direct operating expense driven by loan origination volume. By contrast, interest expense on non-funding debt is a function of our capital structure and is therefore excluded from Adjusted EBITDA. We define “Non-funding debt” as the total of senior notes, lines of credit, borrowings against investment securities, equipment note payable, and finance leases and the “Non-funding debt to equity ratio” as total non-funding debt divided by the total equity. Management believes that these non-GAAP metrics provide useful information to investors. This measure is not a financial measure calculated in accordance with GAAP and should not be considered as a substitute for revenue, net income, or any other operating performance measure calculated in accordance with GAAP and may not be comparable to a similarly titled measure reported by other companies. See Appendix for reconciliation for each non-GAAP measure used in this presentation to the most directly comparable GAAP measure.

KEY INVESTMENT HIGHLIGHTS 3 UWM is at an inflection point—repositioning the business for long-term, through-the-cycle success ⚫ Clear 2030 roadmap: Management is focused on defined objectives that pair operational performance with balance sheet and capital structure improvements ⚫ Sustained market leadership: UWM remains the leading wholesale platform, protecting and extending broker-channel leadership through scale, service, and execution—not simply relying on a rate-driven cycle ⚫ Cycle-resilient earnings power: The business has demonstrated an ability to operate profitably through a challenging mortgage backdrop, underscoring durability and operating leverage as volumes normalize ⚫ Preferred reduction is paramount: Paying down the Oaktree preferred and improving common equity economics remains a core priority, with a deliberate path to simplification over time while maintaining leverage ratios ⚫ Multiple prudent levers: Progress can be driven via internally generated capital, balance sheet optimization, selective financing actions, and other tools—without waiting for a major market turn ⚫ Stable financial policy: Capital management is anchored in prudent leverage targets, meaningful cushion to key constraints, and durable access to liquidity to support growth and navigate volatility ⚫ Upside optionality, not a prerequisite: A more favorable rate environment would be a tailwind and can drive outsized returns—but success for common equity holders is not predicated on rates improving

 
UWM THEN AND NOW 4 THEN NOW Volume Growth and market share expansion were primary strategic priorities, supporting the continued scaling of the platform Focuses on extending broker-channel leadership while balancing growth with profitability, returns, and capital efficiency Leverage Leverage levels reflected the growth priorities and evolving capital allocation strategy Leverage is managed within a defined target framework designed to maintain flexibility and provide a cushion to key thresholds KPIs Investor communication often highlighted market share growth, production volume, and platform expansion Greater emphasis on durable earnings power, returns, cash generation, and long-term shareholder value creation Distributions Capital returns remained an important component of shareholder value creation, alongside continued investment in the business Capital allocation is increasingly focused on strengthening liquidity, retaining earnings, and supporting long-term compounding Hedging Hedging activity evolved alongside significant changes in market conditions and portfolio composition Hedging is positioned as a more targeted and programmatic function, aligned with a stable and disciplined risk framework

RATE CYCLES CREATE DISTINCT ORIGINATION AND SERVICING EARNINGS DYNAMICS 9 Low-Interest Rate Environment High-Interest Rate Environment Refinance activity moderates, resulting in lower industry origination volumes 1 2 Origination Volume MSR Valuation MSR Strategy Earnings Mix Conditional Prepayment Rate (CPR) Shifts toward servicing income and the value of existing MSR assets Typically increases as expected loan lives and cash flows are extended Elevated MSR valuations create opportunities to selectively monetize servicing assets Typically declines as fewer borrowers have an incentive to refinance Increased refinance activity typically drives higher origination volumes Shifts towards origination revenue, gain on sale income, and recapture Typically decreases as higher expected prepayments shorten duration of cash flows Retention of servicing assets may be more attractive when MSR valuations are under pressure Typically increases as borrowers refinance into lower rates UWM is positioned to benefit from both low- and high-rate environments through a combination of origination scale, servicing cash flows, and MSR optionality

Figures represent actual 1st lien mortgage originations during the year as reported by IMF. 2. Based on IMF and FHFA data and annualized by multiplying 2026 first-half actuals by two. 3. The figures contained on this slide are illustrative only. Actual results may vary, and these variations may be material. Nothing in this presentation should be regarded as a representation that these figures will be achieved, and UWM undertakes no obligation to update these figures. Gain-on-sale held constant at 1H’26 annualized rate for illustrative purposes, but historically higher volume typically results in higher gain-on-sale, while lower volume typically results in lower gain-on-sale 4. Actuals represent 1-month CPR on 30-Yr MBS. Each year taken as the 12-month average CPR as reported by Fannie Mae and Freddie Mac for 30-Yr MBS across all coupons. 5. Our belief is that the 1H’26 annualized decline in market share compared to 2025 is largely attributable to a faster loan closing rate at UWM compared to the broader industry.

MULTIPLE PATHWAYS EXIST TO REDUCE PREFERRED BALANCE OVER TIME 12 ⚫ UWM's earnings profile provides a meaningful source of internally generated capital to support future preferred redemptions ⚫ Suspension of the historical common dividend allows a greater portion of earnings to be retained and deployed toward balance sheet optimization ⚫ Preferred redemption premiums accrue over time and do not require annual cash payments Retained earnings1 ⚫ Cash exercise of outstanding warrants could generate a meaningful source of capital as equity value appreciates ⚫ Exercise of the $2 and $6 warrant tranches would provide incremental proceeds that could be deployed toward preferred redemptions ⚫ Warrant proceeds could represent an additional source of balance sheet flexibility alongside retained earnings and debt capacity Warrant exercise2 ⚫ Pro forma capitalization provides meaningful capacity within the Company's targeted leverage framework of <2.0x net non- funding debt-to-equity ⚫ Existing balance sheet flexibility creates the ability to refinance portions of the preferred with lower-cost capital over time ⚫ Growth in common equity would further expand potential debt capacity while maintaining a conservative leverage profile Unsecured debt3 UWM's earnings power, balance sheet flexibility, and potential warrant proceeds provide multiple avenues to reduce preferred balance without relying on a significant improvement in mortgage market conditions
