Key Takeaways for Investors

Underlying performance strengthened: Accident-year ex-cat loss ratio improved to 63.0% vs 65.9% YOY; Insurance combined ratio near break-even (99.5%), indicating better core underwriting despite cats .
Cat losses drove the beat/miss narrative: $56.4mm cat losses (9.4 points) hit margins; still much improved from the exceptional 2017 cat season, supporting YOY ratio improvement .
Margin optics distorted by non-recurring costs: $38.6mm Apollo advisor fees and $11.1mm OEE costs elevated expense ratio (41.9%) and G&A (25.7% vs 17.0% YOY); normalize these for core margin view .
Net written premium and retention fell on purpose: Increased quota shares lowered retention (66.3%) and NWP (-4.7% YOY), reducing volatility and cat exposure at the cost of near-term net growth .
Balance sheet and investment steady: Investment income $48.0mm, book yield 2.67% with AA- credit quality; diluted BVPS $37.46 (down YOY on losses/unrealized AFS marks) .
Transaction path is a key catalyst: Apollo deal “on track” to close H1 2019; governance/leadership transition in motion; watch regulatory approvals and closing conditions (including cat-loss thresholds and ratings maintenance) for timing risk .
Near-term trading: Headlines around cat loss development, non-recurring cost cadence, and merger milestones likely drive sentiment; medium-term thesis hinges on OEE savings realization and continued improvement in accident-year loss ratios .
