Octave Specialty Group, Inc.
A specialty property-and-casualty insurer, it pairs a distribution arm that places premiums across niche insurance lines with Everspan, a program carrier that works with managing general agents and is rated A- by A.M. Best. It began in 1971 as the American Municipal Bond Assurance Corporation (Ambac), a bond insurer that survived the 2008 crisis, then rebranded as Octave in 2025 after selling its legacy financial guarantee business. Its name borrows the musical octave, chosen to suggest distinct businesses working together in harmony.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: -17.5K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
