Second-Quarter Business Highlights:
•SEI delivered strong second-quarter results, with diluted EPS of $1.59 and adjusted diluted EPS of $1.66. On an adjusted basis, EPS increased 38% relative to the prior year, driven by strong revenue growth, margin expansion, and a 3% reduction in share count from SEI’s share repurchase program.
•Second quarter net sales events totaled $43.5 million, bringing year-to-date sales events to $110.6 million. Recurring sales events totaled $32.6 million during the quarter.
◦Private Banks generated $10.1 million of sales events, reflecting continued demand across SEI’s capabilities. Private Banking sales activity was driven by new regional banking client wins, the conversion of clients from TRUST 3000® to the SEI Wealth PlatformSM, and continued momentum for professional services.
◦Investment Managers led the quarter with $32.0 million of sales events. Approximately half came from new client wins, including continued contribution from the two large relationships announced last quarter. The remainder was driven primarily by expanded relationships with existing clients and professional services activity associated with implementing several significant wins announced over the last year. Approximately three-quarters of sales events came from alternative investments.
◦Advisors and Institutional generated negative $2.8 million of net sales events. Sales activity in newer product categories, including ETFs and SMAs, continued during the quarter, though those products generally carry lower fee rates than traditional mutual funds.
•Consolidated revenues and operating income increased by 15% and 33%, respectively, from Q2 2025. On an adjusted basis, operating income increased by 36% with adjusted operating margins increasing to 32%, up 5 percentage points from Q2 2025. Revenue increased by $82.0 million, while expenses increased by $33.6 million, reflecting strong operating leverage despite continued investment across the business.
◦Private Banking revenue increased 11% and operating profit increased 39% versus Q2 2025, as strong sales execution over the past year continued to translate into financial performance.
◦Investment Managers revenue increased 17% and operating profit increased 25% versus Q2 2025 as sales momentum translated into financial performance. Operating margin increased to 40%.
◦Investment Advisors revenue increased 30% and operating profit increased 22% versus the prior year, benefiting from higher market values and the contribution from Stratos. Excluding Stratos, Advisors margins increased by over three percentage points from Q2 2025.
◦Institutional Investors revenue increased 1% versus Q2 2025, while operating profit declined 2%, reflecting continued investment in sales and leadership initiatives.
•Ending assets under administration increased 5% during the quarter, driven by the funding of alternative mandates and market appreciation for traditional mandates. Ending assets under management increased 9.5% to $606.7 billion, driven by strong market appreciation.
•LSV generated $2.0 billion of net inflows during the quarter, driven primarily by the funding of a large new mandate. Combined with market appreciation, total LSV assets increased by nearly $17 billion during the quarter. LSV investment performance remained strong. Performance fees totaled approximately $17 million during the quarter, of which approximately $6.5 million was attributable to SEI.
•During the quarter, SEI repurchased 1.3 million shares of common stock for $112.4 million at an average price of $86.92 per share.

Non-GAAP Information & Reconciliations
(In thousands, except per share data) (Unaudited)
We present certain non‑GAAP financial measures to supplement the consolidated financial statements prepared in accordance with GAAP. Management believes these measures provide useful information to investors by enhancing the understanding of our core operating performance and facilitating comparisons across reporting periods. These non‑GAAP measures are also used by our management to evaluate operating results, allocate resources, and assess performance against strategic objectives.
These non-GAAP financial measures should be viewed in addition to, and not as a substitute for, reported results prepared in accordance with GAAP.
The following schedules reconcile U.S. GAAP financial measures to non-GAAP financial measures for the three and six months ended June 30, 2026 and 2025:

(A) This non-GAAP adjustment removes incremental and directly attributable costs incurred to execute acquisitions, such as third-party advisory, legal, accounting, valuation, and due diligence. For 2025, this non-GAAP adjustment consisted of the legal costs, advisory fees, and due diligence fees in relation to the Stratos acquisition. Management believes adjusting for these charges helps the reader's ability to understand our core operating results and increases comparability quarter to quarter.
(B) This non-GAAP adjustment removes the impact of amortization expense associated with acquired intangible assets (e.g., customer relationships, technology, trade names). This non-GAAP adjustment removes only amortization recorded in the current period related to acquired intangibles from prior acquisitions. The non-GAAP adjustments in 2026 include the amortization of the acquired intangibles from the Stratos acquisition, which closed in December 2025. Management included the Stratos related amortization expense net of the 42.5% NCI adjustment for the adjusted EPS calculation. However, this adjustment is not inclusive of the NCI portion for adjusted operating margin. The associated revenues are not adjusted. Management believes adjusting for these charges helps the reader's ability to understand our core operating results and increases comparability quarter to quarter.
(C) This non-GAAP adjustment removes realized gains on the sale of assets owned or entities under our control, out of the normal course of business. In 2025, the adjustment consisted of the realized gain from the sale of Family Office Services (FOS). Management believes adjusting for these gains helps the reader's ability to understand our core operating results and increases comparability quarter to quarter.
(D) This non-GAAP adjustment removes individually significant litigation settlements and insurance proceeds. In 2026, this non-GAAP adjustment was related to litigation settlements. In 2025, this non-GAAP adjustment consisted of a $4.5M settlement related to a vendor matter. Management included both of these transactions as non-GAAP adjustments since they were both out of the normal course of business. Management believes adjusting for these items helps the reader's ability to understand our core operating results and increases comparability quarter to quarter.
(E) Income tax effects are presented as a separate reconciling item (not netted within each adjustment). For performance measures, the tax effect reflects current and deferred tax expense commensurate with the adjusted measure of profitability. The methodology used (e.g., statutory rate, effective rate, or discrete item approach) is consistently applied. All of the above items use a systematic approach.

In some cases you can identify forward-looking statements by terminology, such as "may," "will," "expect," "believe," ”remain” and "continue" or "appear." Our forward-looking statements include our current expectations as to: • the impact, if any, that our activation and execution of our strategic goals will have on our financial results; • whether the investments we have made in the future of our business will become meaningful contributors to our next phase of growth; • the expansion of private markets into retail and retirement channels and the degree to which we will benefit from this expansion, if any; • the degree to which our strategic and tactical direction will make our asset management business stronger and more competitive; • the benefits to us and our clients of embedding Artificial Intelligence into our workflows; • our ability to expand our client opportunities into larger, more strategic, enterprise-wide engagements; • our ability to win large opportunities that leverage existing capabilities, require less incremental investment and contribute more quickly to financial results; • our level of engagement with the largest and most sophisticated firms in our target markets; • our ability to convert sales events into revenue as well as the speed of this conversion; • the benefits, if any, of our operating discipline and cost controls; • the repeatability of our sales success; • the contributions to revenue from two large Investment Manager Services relationships announced last year; • the durability of and growth in demand for alternative investments; • the success of our re-contracting activity; • the repeatability of our quarterly results; • our ability to consistently execute against our strategy; • strength of the sales momentum in our businesses and whether this momentum will continue; • our strategic priorities and focus; • how we will use and deploy our capital and the reasons for our capital allocation methodologies; • the opportunities for us in the area of Artificial Intelligence and the effect our investments and experiments in Artificial Intelligence will expand our addressable markets; • the level of demand for outsourcing, investment advice and the margin sensitivity of these services; • the benefits that we and our stakeholders will receive as a consequence of our partnership with Stratos Wealth Management; • the potential consequences resulting from our exposure to private credit and the demand for our services from our private credit clients; • our 2026 priorities and commitment to these priorities; • the market dynamics affecting our businesses; • our ability to improve our consolidated margins • our ability to deliver strong financial performance and fund future growth initiatives • our growth outpacing our expenses; • the expansion of our enterprise engagement; • the robustness of activity in our IMS business; • the revenue we derive from alternative investment mandates; • the strength of our pipelines; • the level at which we return capital to shareholders and repurchase our stock; • the demand for our products and services; and • our ability to deliver long-term value for clients, employees and shareholders. You should not place undue reliance on our forward-looking statements, as they are based on the current beliefs and expectations of our management and subject to significant risks and uncertainties, many of which are beyond our control or are subject to change. Although we believe the assumptions upon which we base our forward-looking statements are reasonable, they could be inaccurate. Some of the risks and important factors that could cause actual results to differ from those described in our forward-looking statements can be found in the "Risk Factors" section of our Annual Report on Form 10-K for the year ended Dec. 31, 2025, filed with the Securities and Exchange Commission. Past performance does not guarantee future results. Safe Harbor Statement 2 SEI Earnings PresentationQ2 2026
