Watch Items from the Filing
Q3 other expense of $32.5M reflects a one-time charge under the Stratos Second Stage termination agreement, which depressed net income growth to 4%.
Stratos contributed $126.7M of nine-month revenue but also $20.1M of acquired intangible amortization, weighing on Investment Advisors margins.
Rubicon litigation remains pending; SPTC estimates approximately $13,500 of client assets directed to the Orchard Park entity, with losses unlikely to exceed that amount if the defense fails.
Company repurchased 2.0M shares for about $215M in Q3 and an additional $800M buyback authorization was approved October 20, 2026.
