SEI Investments slides as revenue miss outweighs margin gains after Q1 results

SEICSEIC

SEI Investments shares fell about 3% on April 24, 2026, as investors digested a Q1 revenue miss despite strong profit growth. The company reported Q1 revenue of $622.2 million versus $633.2 million expected, while adjusted EPS rose to $1.44.

1. What’s moving the stock

SEI Investments (SEIC) is trading lower on April 24, 2026, as the market focuses on a top-line shortfall from this week’s quarterly report. SEI posted first-quarter revenue of $622.2 million, below the $633.2 million consensus cited in earnings recaps, even as profitability improved meaningfully.

2. The numbers investors are reacting to

For the quarter ended March 31, 2026, SEI reported diluted EPS of $1.40 and adjusted EPS of $1.44. Operating margin expanded to 30% (32% on an adjusted basis), reflecting faster growth in operating income than revenue and continued operating leverage.

3. Why the reaction is negative today

After an initial post-earnings reaction earlier in the week, Friday’s pullback looks like a reassessment of growth quality: strong margins and EPS can support valuation, but a revenue miss can raise questions about near-term net flows, fee growth, and the pace at which sales wins translate into sustained revenue. The stock’s decline suggests investors are prioritizing evidence of durable top-line acceleration over incremental profitability gains.
