What Management Said

Here are the key debates and direct quotes from Arch Capital Group's Q4 2025 earnings call:

Property Catastrophe Reinsurance Pricing, ROE Thresholds, and Growth Appetite

Sentiment: Positive

"Overall, I think we still like the the the cat business we we we wrote at one one... we we we were able to, you know, retain most of our renewals... but if rates were to continue to to go down you know, in the mid teens, you know, we we we we we will have to on the case by case basis, you know, realize where it makes sense and where where where it doesn't." — Nicolas Papadopoulo
"On January 1, property cat and more generally, short-tail excess of loss renewals were highly competitive with rates down 10 to 20%... Despite these headwinds, our underwriting teams performed well, leveraging the strengths of our platform to source a handful of new opportunities. These opportunities will reduce the negative top-line impact from the rate pressure." — Nicolas Papadopoulo

Capital Management, Share Repurchases, and “Excess Capital” in a Slowing Market

Sentiment: Positive

"Share buybacks are, I think, certainly, as we said, like a good way to return capital... we don't set a target that not like we're we're saying we're gonna return x dollars by the end of the year, but you know... given the the market environment we're in, I think we should expect us to to be pretty active on the share buybacks throughout the year." — François Morin
"If we're not growing... their our capital needs should remain relatively flat, and every dollar of, you know, income that we generate technically could be you know, creating more excess capital... if the opportunity is there to buy back you know, more than you would know, you see us saw us buyback last year, for example, we're happy to do that." — François Morin

Casualty Reinsurance Conditions, Margins Under Pressure, and Growth vs Discipline

Sentiment: Mixed

"On the casualty side... on the primary side, feel that rates are still know, we are still getting more rate than trend... but when we look at specifically at the reinsurance, I think the we've seen, you know, there's there's there's a there's a lot of supply... and the ability or the willingness of the the selling companies to to retain more of the business... so that that that is another layer of a competition there." — Nicolas Papadopoulo
"We we we believe that we we can find ways to to continue to track attractive attractive market, but, yes, the margin mean, they were very high, but the the margins are definitely under pressure." — Nicolas Papadopoulo

Segment‑Level Growth Priorities: Reinsurance vs Insurance vs Mortgage

Sentiment: Positive

"No question that reinsurance has been you know, the last couple of years, definitely, you know, the you know, a very attractive market for us... As the market comes down, it's I think it's it's it's a less, you know, ahead of the others, I would say... if I had to rank them today, I'd say, yeah, reinsurance to me is still ahead, but you know, the gap has narrowed." — François Morin
"Mortgage... we love it. Right? I mean, just a great business. It's it's steady. It's been a great source of earnings for us... the fact that the reinsurance market is is compressing a little bit, I think, just brings all three segments a bit closer to each other." — François Morin

Insurance Segment: MCE Acquisition Re‑underwriting, Program Non‑renewals, and Margin Impact

Sentiment: Positive

"There was definitely some business that came with the acquisition primarily in, in the form of programs that we identified that were gonna be nonrenewed. We've we've done that work that will start to really [hit] our top line in 2026... depending on market conditions, can offset some of that reduction by growth in the truly the middle market business that we we have on the books." — François Morin
"Some of the program we've shared are actually cat exposed. So, you know, the the the upfront the upfront result may have looked okay, but we think it's a it's a bad allocation of capital, and we can get better return by deploying that capacity elsewhere... overall, I think we we still, you know, thinking that the business could run-in... in the low nineties." — Nicolas Papadopoulo
