Accelerant Holdings (ARX) – Insider Ownership Update
COO Matthew David Sternberg filed an amended Form 3 reporting one derivative position: an employee stock option covering 884,464 Class A shares at an exercise price of $19.31. Twenty-five percent vested after one year; the remaining 75 % vest in 6.25 % quarterly tranches over the next three years. The option expires 09/01/2033. The amendment corrects the 07/23/2025 filing, which overstated the share count by one share and understated the exercise price by $0.01. No non-derivative holdings were disclosed, and the filing does not alter share count, dilution, or cash flow for existing investors.
Accelerant Holdings (ARX) – Form 3/A: Director Paul Christopher Little discloses ownership of a single stock-option grant covering 165,831 Class A shares with a $19.31 exercise price. Twenty-five percent vests after one year; the remaining 75% vests in 6.25% quarterly installments over the next three years, contingent on continued service. This amendment corrects the prior Form 3 filed 23 Jul 2025, reducing the option by one share and increasing the exercise price by $0.01. No other equity positions or material changes are reported.
Accelerant Holdings (ARX) Form 4 filing: Co-founder & CEO Jeffrey L. Radke was granted 8,279,552 stock options on 23 Jul 2025 at an exercise price of $21 per Class A common share. The options expire on 23 Jul 2035.
Vesting schedule: 25 % vests on 23 Jul 2026; the remaining 75 % vests in 6.25 % quarterly tranches through 23 Jul 2029, subject to continuous service. Following the grant, Radke beneficially owns the full 8.28 M derivative securities directly.
Take-aways for investors: the award is sizable and represents future dilution if exercised, but it strengthens management-shareholder alignment and serves as a long-term retention incentive for the CEO.
On 07/23/2025, Co-Founder & Chief Underwriting Officer Francis James O’Neill received a stock option covering 882,611 Class A common shares of Accelerant Holdings (ARX) at an exercise price of $21, as disclosed in a Form 4 filed 07/25/2025.
Vesting terms tie the award to long-term service: 25% vests on 07/23/2026 and the remaining 75% vests in 6.25% quarterly installments through 07/23/2029. The award is coded “A,” indicating a grant with no cash payment or share sale. O’Neill now beneficially owns 882,611 derivative securities, all held directly.
The grant increases potential dilution if exercised but aligns executive compensation with future share-price performance by requiring four years of continued service before full vesting.
Accelerant Holdings (ARX) filed a Form 4 indicating that Co-Founder, Director and Head of Distribution Christopher Lee-Smith received a new stock-option grant on 23 Jul 2025.

After the transaction, Lee-Smith beneficially owns 2,746,261 derivative securities; no non-derivative share movement was disclosed.
