Executive Summary / Key Takeaways

• Outsourcing Megatrend Driving Record Sales: SEI is capitalizing on a fundamental shift as asset managers and banks move from in-house operations to integrated platforms, generating nearly $130 million in net sales events for 2024 (almost double 2022 levels) and surpassing $100 million year-to-date through Q3 2025.
• Capital Allocation as a Competitive Weapon: The company returned $775 million to shareholders over the trailing twelve months (reducing shares outstanding by over 7%) while simultaneously funding strategic investments like the $527 million Stratos partnership and $29 million LifeYield acquisition, demonstrating disciplined deployment of its $793 million cash hoard.
• Margin Expansion Trajectory: Operating margins hit 28.5% in Q1 2025, the highest level in three years, driven by platform scalability and the high-margin Integrated Cash Program, though management expects near-term pressure from growth investments.
• Technology Moat Deepening: The SEI Wealth Platform and new SEI Scope platform, combined with AI/tokenization initiatives in "early innings," position SEI to capture more wallet share as clients consolidate vendors.
• Key Risks to Monitor: UK regulatory scrutiny of SIEL restricting new client agreements, persistent LSV outflows from active manager headwinds, and execution risk on large alternative manager conversions could pressure the growth narrative.

Setting the Scene: From Asset Servicer to Platform Provider

SEI Investments Company, founded in 1968 and headquartered in Oaks, Pennsylvania, has evolved from a traditional investment administrator into a technology platform provider serving the $100+ trillion global asset servicing market. The company operates through four core segments: Investment Managers (outsourced operating platforms for asset managers), Private Banks (investment processing for banks and trust institutions), Investment Advisors (platforms for RIAs), and Institutional Investors (OCIO solutions). This structure positions SEI at the intersection of wealth management, retirement services, and investment operations.

The industry is experiencing a structural inflection point. Asset managers, particularly in alternatives, are abandoning in-house administration due to complexity and cost pressures. Banks are rethinking operating models, seeking to outsource non-core functions. This creates a powerful tailwind for SEI's integrated platform approach. The competitive landscape includes custody giants like State Street (STT) and BNY Mellon (BK) with scale advantages, technology providers like SS&C Technologies (SSNC) with acquisition-driven portfolios, and asset managers like T. Rowe Price (TROW) with proprietary fund offerings. SEI's differentiation lies in its advisor-centric technology stack and end-to-end ecosystem, enabling materially lower implementation costs and faster deployment for mid-market clients versus the higher-touch, scale-dependent services of custody banks.

Technology, Products, and Strategic Differentiation

The SEI Wealth Platform (SWP) represents SEI's primary moat, offering an integrated technology stack that combines investment processing, data analytics, and client experience tools. Unlike competitors' fragmented solutions, SWP provides end-to-end processing with significantly higher efficiency in data integration and compliance. This translates to superior recurring revenue (over 90% of total) and faster innovation cycles, supporting pricing power and customer loyalty.

The new SEI Scope platform, launched in Q3 2025 for the Investment Managers segment, extends this advantage by addressing specific needs of alternative asset managers. Capitalized software development of $22.8 million in the first nine months of 2025, with $14.5 million allocated to SWP enhancements and $8.3 million to SEI Scope, demonstrates continued investment in platform differentiation. The Integrated Cash Program exemplifies SEI's ability to monetize its infrastructure, generating $62.3 million in revenue during the first nine months of 2025 (up from $30.4 million in 2024) by earning 370 basis points while paying investors 55 basis points. This 315 basis point spread creates a high-margin revenue stream that competitors cannot easily replicate.

The December 2024 acquisition of LifeYield for $29 million plus contingent consideration integrates tax-smart technology into the Investment Advisors segment, enhancing SEI's value proposition for RIAs focused on tax optimization. Management describes the company as being in the "early innings of AI and tokenization," applying AI to internal workflows and advancing tokenization pilots with partners. While still nascent, these initiatives could drive future efficiency gains and scalability, further widening the moat against legacy providers.

Financial Performance & Segment Dynamics: Evidence of Platform Value

SEI's Q3 2025 results provide compelling evidence of the platform transformation thesis. Revenue reached $579 million, with EPS hitting $1.30—an all-time high for the company, excluding one-time items. This performance was broad-based, with the Investment Managers segment posting record sales and the Investment Advisors segment delivering 16% revenue growth.

The Investment Managers segment generated $207 million in revenue (up 12% year-over-year) with a 39% operating margin, driven by surging demand for outsourcing from alternative asset managers. Approximately two-thirds of Q3 sales came from client expansions and two-thirds from alternative managers, indicating both deepening relationships and new client acquisition. The segment's pipeline includes large alternative managers new to outsourcing, with clarity expected in early 2026 due to deal complexity. This validates SEI's leading market position with alternatives, which accounted for nearly 70% of segment revenue in 2024.

Investment Advisors delivered $147 million in revenue (up 16%) with a 46% operating margin, benefiting from market appreciation and the Integrated Cash Program. The cash program contributed $10 million to operating profit versus the prior year, demonstrating its margin-accretive nature. Net inflows into separately managed account programs and strategist programs offset outflows from mutual funds, showing successful execution of the strategy to shift resources toward higher-margin, tax-sensitive products.

Private Banks posted $144 million in revenue (up 4%) with a 16% operating margin. The segment secured a $13 million win with a super-regional U.S. bank for a comprehensive transformation initiative, affirming SEI's pivot to leadership in the regional bank segment. However, a contract loss in Q3—identified as a risk since 2022 due to the client's strategic shift—offset some gains. Management emphasized this was a one-off event, not a trend, with modest financial impact as fee conversions occur over multiple years.

Institutional Investors reported flat revenue of $72 million with a stable 47% operating margin. The segment achieved its largest mandate win to date: a multibillion-dollar fixed income assignment for a state government client, demonstrating SEI's ability to compete for specialized mandates despite structural headwinds from corporate defined benefit plan terminations.

The LSV asset management affiliate remains a headwind, with earnings declining to $94.3 million in the first nine months of 2025 (from $102.4 million in 2024) due to negative cash flows and client losses. Nearly $3 billion in net outflows in Q3 mirrored the first-half pace, reflecting industry-wide pressures on active managers. While market appreciation partially offset outflows, LSV's performance fees are expected to moderate from 2024's $21 million level.

Capital allocation excellence shines through the financials. SEI returned $775 million to shareholders over the trailing twelve months via buybacks, reducing shares outstanding by over 7%. The company ended Q3 with $793 million in cash and no net debt, while maintaining a $500 million credit facility with $495 million available. This financial strength funds both growth investments and returns of capital, a rare combination in the asset servicing industry.

Outlook, Guidance, and Execution Risk

Management's guidance reveals confidence tempered by realism. SEI expects to return 90-100% of free cash flow to shareholders, primarily through buybacks, while maintaining excess cash to fund the Stratos acquisition. The initial closing of the $527 million investment for a 57.5% stake in Stratos Wealth Holdings is expected in late 2025 or early 2026, with put/call options to acquire 100% over 72 months. This partnership aims to integrate Stratos' client-centric model with SEI's technology, custody, and investment management capabilities, potentially adding tens of millions in revenue from future M&A activity.

Margin expansion remains a priority, but management acknowledges near-term pressure. The Investment Managers segment faces costs layering on as quickly as revenue as SEI staffs for larger client conversions, with margins expected to remain flat or experience a slight downtick into 2026. This reflects a deliberate choice to prioritize growth over short-term margin maximization. As CFO Sean Denham stated, "If that required us to take the margins down a little bit in IMS, we would be more focused on SEI's margins and what we would do in other units to make sure SEI's margins continue to grow and expand."

The Integrated Cash Program's benefit is expected to moderate in 2025 as clients explore alternative cash options and short-term interest rates decline. Paul Klauder noted that for every 25 basis point rate cut, SEI typically reduces the investor yield by 15 basis points while taking a 10 basis point hit to its spread, though a floor exists. This headwind is manageable given the program's relatively small size but will pressure advisor segment margins.

Institutional headwinds from defined benefit plan terminations are expected to persist through 2025. Elevated interest rates make it advantageous for plans to annuitize liabilities, creating ongoing pressure on assets under management. This structural challenge is partially offset by wins in specialized mandates but remains a drag on segment growth.

Risks and Asymmetries: What Could Break the Thesis

The UK Financial Conduct Authority's supervisory review of SEI Investments Europe Limited (SIEL) presents a material regulatory risk. Since July 2024, SIEL has faced a two-stage review of its governance and control environment. As of February 2025, SIEL is restricted from entering new client agreements or launching new propositions without FCA consent if these require material changes or significant senior management engagement. While management believes remediation actions will address concerns, the restriction could slow European growth and increase compliance costs. The direct and indirect costs of responding to regulatory activities are uncertain but could be material.

LSV's persistent outflows represent a structural vulnerability. The affiliate experienced nearly $3 billion in net outflows in Q3 2025, consistent with the first-half pace. This reflects broader industry pressures on active asset managers as investors shift to passive strategies. While LSV's long-term performance remains strong on three- and five-year bases, the trend threatens a key earnings contributor. Performance fees, which reached $21 million for SEI's share in 2024, are expected to moderate, creating a headwind of several million dollars annually.

Execution risk on large alternative manager deals could pressure margins and reputation. SEI is engaging with large alternative asset managers new to outsourcing, with deals expected to close in early 2026 due to their size and complexity. These conversions require significant upfront investment in staffing and technology. If the pace of wins accelerates as anticipated, near-term margins could suffer. As Ryan Hicke noted, "As we win new business, we must augment our teams and the associated costs ahead of onboarding a client on time and on budget. As a result, the expense hits the income statement before revenue."

The Private Banks contract loss, while described as a one-off event, reveals client concentration risk. The client represented a strategic shift away from the bank trust model, a risk SEI had identified since 2022. Sanjay Sharma emphasized this was the first loss in over three years and not a trend. However, it highlights that large client relationships can unwind due to strategic changes beyond SEI's control, potentially impacting multi-year revenue streams.

Valuation Context: Positioning Relative to Cash Generation

At $81.00 per share, SEI trades at a market capitalization of $10.01 billion with an enterprise value of $9.22 billion, reflecting its net cash position. The stock's valuation multiples suggest a market that recognizes the company's cash-generative capabilities but remains cautious about growth sustainability.

SEI's price-to-free-cash-flow ratio of 16.11x and price-to-operating-cash-flow ratio of 14.80x position it attractively relative to peers. SS&C Technologies trades at 16.28x free cash flow but with a higher P/E of 25.37x, reflecting its acquisition-driven growth model and higher debt load (debt-to-equity of 0.97 versus SEI's 0.01). State Street's P/E of 12.65x appears cheaper but includes banking operations with different capital requirements and regulatory burdens. BNY Mellon's P/E of 16.32x and negative enterprise value (due to net cash) reflect its custody-focused model with lower growth prospects. T. Rowe Price's P/E of 11.18x reflects its pure asset management exposure and sensitivity to active manager headwinds.

SEI's operating margin of 27.65% and profit margin of 31.09% exceed SS&C's 23.32% and 13.86%, demonstrating superior operational efficiency. The company's return on equity of 29.28% significantly outpaces custody banks (STT: 11.15%, BK: 12.15%) and approaches T. Rowe Price's 18.67% despite a more diversified business model. This reflects SEI's ability to generate high returns without excessive leverage.

The balance sheet provides strategic flexibility that competitors cannot match. With $793 million in cash, no long-term debt, and a $500 million credit facility, SEI can fund the $527 million Stratos investment while maintaining its aggressive buyback program. The company's 18.05% payout ratio leaves ample room for dividend growth, while the 1.23% dividend yield supplements the primary capital return mechanism of share repurchases.

Conclusion: Platform Moat Meets Capital Discipline

SEI Investments has engineered a compelling investment case at the intersection of two powerful themes: a technology platform transformation capturing the outsourcing megatrend, and capital allocation excellence that systematically returns value to shareholders. The record sales momentum—nearly $130 million in 2024 and over $100 million year-to-date—demonstrates that asset managers and banks are consolidating vendors and choosing SEI's integrated platforms. This is translating into margin expansion, with operating margins reaching 28.5% in early 2025, the highest level in three years.

The central thesis hinges on execution of large alternative manager conversions and resolution of regulatory overhang in the UK. If SEI can convert its strong pipeline of large alternative managers while maintaining its "enterprise-first mindset" of investing ahead of growth, the platform moat will deepen and margins can expand further. The Stratos partnership, while dilutive to cash in the near term, positions SEI to capture advisor consolidation trends and provides a vehicle for future M&A.

For investors, the key variables are the pace of outsourcing adoption in alternatives, the trajectory of LSV outflows, and the timeline for lifting FCA restrictions on SIEL. The stock's valuation at 16x free cash flow appears reasonable for a company generating 29% returns on equity with a net cash balance sheet. If SEI executes on its platform strategy while maintaining its disciplined capital returns, the combination of recurring revenue growth and aggressive share repurchases could drive meaningful per-share value creation even in a challenging market environment.
