Prosper Stars & Stripes stated the following regarding Accelerant Holdings (NYSE:ARX) in its third quarter 2025 investor letter:

“Accelerant Holdings (NYSE:ARX) was the largest detractor in the long book during the third quarter of 2025. The company operates a specialty insurance marketplace connecting Managing General Agents (“MGAs”), the supply, and risk capital providers, the demand. Accelerant provides operational and regulatory support with a five-year commitment of table underwriting capacity to MGAs. And for risk capital providers, the company provides cost effective access to a diversified portfolio of small commercial specialty premiums. Revenue growth is primarily a function of Exchange Written Premiums (“EWPs”). It is presented as a low-risk model with recurring revenues. ARX was a recent IPO with growth opportunities due to its recent track record and potential of the business model. Despite pre-releasing most of its first quarter as a public company, the full report detailed a few items that investors took issue with. Specifically, questions about a large contribution to growth from a related party was concerning and the stock fell. We exited our position noting increased risks and that the company did not handle its initial phase as a public company well.”
