Insperity shares plunged 23.3% post-earnings, as investors reacted negatively to weak paid worksite employee metrics and a cautious outlook for the remainder of the year. Deceleration in core unit growth and visibility on future improvement appeared to disappoint, overshadowing modest progress in margins.

• Paid worksite employees averaged 303,049 in Q1 2026, a 1% decrease year-over-year, landing at the low end of guidance; new client sales-related worksite employees declined 7%.
• Gross profit fell 3% to $302 million, though showing improvement relative to Q4 2025’s steeper decline.
• Gross profit per worksite employee was $332/month, slightly above forecast, primarily due to lower benefit costs.
• Adjusted EPS of $1.31 declined 17% from Q1 2025, partially driven by a higher effective tax rate (41% vs. 29% last year).
• Management emphasized cautiousness around full-year outlook, citing the impact of ongoing margin recovery efforts and delayed net hiring within the client base.
