Analyzing Domino's Strategies for Market Share Growth in Q1 2026

Key factors behind SEIC’s strong sales momentum in Q1 2026

SEI described Q1 2026 sales momentum as the result of repeatable execution across core growth engines (not a one-off market tailwind), and backed that claim with unusually strong and high-quality “sales events” performance. Specifically, SEI delivered $67 million of net sales events in Q1, including $57 million recurring revenue and $10 million professional services, which exceeded its prior quarterly record by more than 40%. ¹

Below are the main drivers SEI cited for that momentum.

1) Investment Manager Services (IMS): enterprise outsourcing “big deals” driving recurring wins

SEI’s largest sales engine in Q1 was Investment Manager Services, contributing more than $50 million of net sales events, and SEI said these were driven by large enterprise mandates and that “portions of these wins accounted for just over half” of total IMS sales events. ²

Management also emphasized that these Q1 sales events reflect the initial phase of multiple enterprise-level mandates with first-time outsourcers—the “big deals” it had been discussing—and that these relationships are designed to expand over time as the client deepens the partnership and progresses with fundraising/new product launches. ¹

Further reinforcing competitiveness and pipeline strength, management said SEI won 2 of the largest and most complex alternative managers in the entire industry, with moves from in-sourcing to outsourcing, and that these were “extremely competitive” bake-offs lasting over a full year. ³ SEI also characterized the pipeline as strong by noting it is “talking to 20 of the top 50 alternative managers right now” and expects sales events to continue to trend up year-over-year. ³

2) Professional Services: earlier, more strategic engagement with faster revenue realization and improving margins

SEI attributed sales momentum in Professional Services not just to demand, but to a change in sales “playbook”: clients are engaging SEI earlier, and SEI is now leading with enterprise capabilities rather than only leading with platform change initiatives. ⁴

SEI also said Professional Services helps explain both growth and margin expansion, and that Q1 execution showed judicious deal selection—management said new Professional Services contracts are coming with higher margin—and pointed to the role of GCC initiative and SaaS expense discipline. ⁵

Separately, SEI linked sales-event timing to revenue recognition by saying it is playing a more active role in client implementations, which creates less lag time between contract wins and revenue recognition. ⁶

In Q1, management quantified the sales-event contribution from Professional Services as $10 million of professional services within the total $67 million sales events. ¹ It also highlighted additional Professional Services-related international engagement: management said more than 1/3 of Professional Services sales events generated internationally in Q1 and that it began building out its Singapore presence as part of global expansion. ⁷

3) Asset Management: strong inflow-related sales events, especially ETFs/SMAs/custody-only

SEI tied overall sales momentum to Asset Management activity, describing Q1 as the strongest sales events quarter in several years. ² It stated this was driven by growing demand for ETFs, SMAs, and custody-only platform offerings. ²

It quantified flow momentum as approximately $1.5 billion of net inflows in Q1, and separately described market/discretion factors affecting outflows (institutional outflows of less than $1 billion, “almost entirely” from a defined benefit client annuitization following funding objectives). ⁸ Management indicated that, based on pipeline visibility, it expected improved flow performance over the remainder of the year. ⁸

4) International traction: professional services scaling outside the U.S.

SEI specifically called out international execution as a sales driver, emphasizing disciplined operations outside the U.S. with accountability for growth, margins, and capital deployment. ⁷

Concretely, SEI reported more than 1/3 of Professional Services sales events were international in Q1, and it referenced continued expansion via its Singapore presence. ⁷

Additionally, management said Professional Services demand is building in the international market as well, noting (in a Q&A) that internationally, 1/3 of Professional Services wins came in the U.K. market. ⁴

5) Higher-quality, repeatable execution across the “5 strategic pillars”

SEI framed Q1 sales momentum as validation of its strategy laid out at Investor Day, stating the quarter was “decisive validation” of the five strategic pillars rather than an anomaly. ¹

While the call covers multiple pillars, the sales-momentum implications are clearest in pillars tied to (a) IMS outsourcing demand, (b) Professional Services enterprise engagements, (c) margin discipline and operating model improvements, and (d) international expansion. ^{1 7}

Management also explicitly distinguished Q1’s sales events as progress in core engines rather than a single market tailwind or discrete event, stating this “distinction matters” because it supports confidence the result is not a one-off. ¹

6) Partnership/integration ecosystem expansion supporting pipeline durability (Stratos and IBM)

SEI pointed to ecosystem depth and infrastructure/automation initiatives as supporting the durability and scalability of growth engines that produce sales events.

• Stratos integration: SEI said Q1 included its first full quarter with Stratos, which “strengthen[s] the overall reach and relevance of our platforms,” and management characterized Stratos integration as well underway with workstreams focused on scalable infrastructure and building a centralized investment hub. ^{7 9}
• IBM partnership: SEI cited a partnership with IBM as reinforcing infrastructure modernization, automation, and responsible AI deployment, described as accelerating the enterprise excellence direction. ⁹

While these are not sales-event counts themselves, SEI explicitly tied operational execution and enterprise partnerships to the ability to deliver consistently and build capacity for growth—mechanisms that management said underpin sales momentum. ^{9 10}

Summary

SEI’s strong Q1 2026 sales momentum is best explained by a combination of:

1. IMS enterprise outsourcing “big deals” producing unusually high recurring and total sales events, including highly competitive wins of top alternative managers with long bake-offs and a large active pipeline. ^{1 2 3}
2. Professional Services benefiting from earlier and more strategic enterprise engagement, faster implementation-to-revenue linkage, international scaling, and higher-margin contract mix and expense discipline. ^{4 6 5 7}
3. Asset Management delivering its best sales-events quarter in several years, driven by demand for ETFs/SMAs/custody-only, supported by about $1.5B net inflows and improving expected flow performance. ^{2 8}
4. A strategy-backed, repeatable execution framework across five strategic pillars, with supporting ecosystem partnerships (e.g., Stratos, IBM) aimed at scaling and durability. ^{1 7 9}

All of these factors together supported record-setting net sales events in Q1 (up to $67M total, and >40% above the prior quarterly record). ¹
