ACGL · Q4 2025 Earnings
CautiousArch Capital Group
Reported February 9, 2026
30-second summary
30-second take: Arch closed 2025 with a Q4 combined ratio of 80.6% and an 18.9% annualized operating ROE, capping a $19.9B revenue year (+13% YoY) and $9.84 of full-year operating EPS. The numbers are still excellent — but management's posture changed materially this quarter: explicit acknowledgement that "margins are definitely under pressure," reinsurance ranked only marginally ahead of insurance versus a clear lead a year ago, and a "measured optimism" framing for 2026 that walks back the offensive capital deployment language from Q3. The cycle clock has moved past 2pm, and Arch is now telling investors it will manage the down-slope rather than chase growth.

Management tone
Q1 (acquisition-defensive) → Q2 (evasive on MidCorp, defensive on cat ROEs) → Q3 (offensive, lean-in, capital deployment) → Q4 (measured optimism, cycle management, margin pressure acknowledged).
The single biggest shift is the explicit reversal on margin direction. One quarter ago management was framing Arch as "well positioned to outperform in an increasingly competitive market" and deploying $732M of buybacks during wind season as a sign of structural confidence. This quarter the language is "I think margins are definitely under pressure…on the expense side…ceding commission…going up." Two quarters ago management refused to quantify how far property cat ROEs had compressed from 30%+; this quarter they volunteered that property cat rate declines are running 10–20% at 1/1, and stated they would write that business "on a case-by-case basis" if rates fall further into the mid-teens. That is a candid concession that the highest-margin window in this cycle is now firmly behind them.
The relative ranking of segments shifted in a way that matters for capital allocation. A year ago — and as recently as Q3 — reinsurance was the clear top capital-deployment priority. This quarter, in response to a direct ranking question from Mizuho, management said reinsurance is "still ranked first but the gap has narrowed" with insurance, and that all three segments are "becoming closer in attractiveness." Combined with the Q&A disclosure that Arch is actively evaluating switching reinsurance program structures from quota share to excess of loss to retain more premium, this suggests a tactical rebalancing toward insurance retention is underway — exactly the opposite of how Arch has historically deployed incremental capital at this point in a cycle.
The cycle metaphor itself is new and pointed. "As we move past 2 p.m. on the P&C underwriting clock, it is increasingly important to focus on business that generates adequate risk-adjusted returns." Arch is now publicly framing the soft market not as a risk to manage but as the operating environment. The Q3 emphasis on "capital deployment as aggressively as possible" has been replaced by a low-90s combined ratio target framing — still strong absolute returns, but explicitly down from where they have been printing.
Hedging language returned after being notably absent in Q3. "We are starting from a position of strengths that recognize that competition is increasing," "subject to a number of risks and uncertainties," "if rates were to continue to go down…we would have to, on the case-by-case basis." For a management team whose Q3 commentary was unusually direct, the reappearance of conditional phrasing across multiple topics is itself the tone signal.

Q&A highlights
Yaron Kinar · Mizuho
Can you elaborate on retaining more premiums in 2026 given rising seeding commission rates and buyer's market conditions? Is the margin on new casualty and specialty business better than seeding at lower pricing?
Management explained they evaluate retention vs. seeding economics on a case-by-case basis. Rate increases on primary side have compounded, making primary insurance attractive. They're also considering switching reinsurance program structures from quota share to excess of loss to retain more. Multiple programs evaluated throughout year depending on market conditions.
Yaron Kinar · Mizuho
How do you rank the appetite and attractiveness of new business between the three segments (insurance, reinsurance, mortgage) in terms of capital deployment for 2026?
Reinsurance still ranked first but gap has narrowed as market compresses. Reinsurance remains very attractive but is less ahead of insurance than a year ago. Mortgage continues as steady, great source of earnings with no material change in appetite.
Matthew Heimerman · Citi
Regarding MCE re-underwriting, what are the margin consequences of shedding business? Will margins improve from non-renewals despite market changes?
Non-renewals of worst-performing business should improve margins absent other events. However, market conditions may differ from assumptions. Some programs being shed are cost-of-capital issues where capacity can be deployed elsewhere. Management expects low 90s combined ratio potentially achievable, particularly in middle market business which has held rates well.
Matthew Heimerman · Citi
Are you seeing changes to subject premium basis in reinsurance treaties that might affect demand for casualty reinsurance, or is there risk to casualty premium assumptions?
On property side, companies have revised projections downward for E&S and energy. On casualty, the reference is to insureds retaining more, but underlying business still growing, so no downward pressure expected. Management actively reviews premium projections quarterly with underwriters and seeding companies, superimposing their own views to avoid large downward adjustments.
Roland Mayer · RBC Capital Markets
What is the current carrying value of the deferred tax asset and when will there be clarification on recognizing it?
Deferred tax asset of approximately $1.2 billion as of start of 2025 was reduced by ~$100 million in 2025 and will continue amortizing in 2026. Asset may be eliminated in late Q4 2026 or early 2027 depending on Bermuda government law changes and negotiations. Recognition depends on Bermuda legislative decisions, not company control.
Answers to last quarter's watch list
What to watch into next quarter
Insurance organic growth recovery or further deceleration. Q4 came in at +2.1% YoY. Watch whether Q1 prints above +5% (suggesting the $200–300M MCE shed explains most of the deceleration) or stays in the low single digits (suggesting underlying organic growth is genuinely soft).
Reinsurance NPW direction at 1/1 renewals. Q4 reinsurance growth of +4.6% YoY masks property cat rate declines of 10–20% and rising seeding commissions. Watch whether Q1 reinsurance NPW prints negative on a reported basis or whether mix shifts (more casualty, less property) hold the headline positive.
Combined ratio trajectory toward management's low-90s framing. Combined ratio rose 80bps QoQ to 80.6% in Q4. Management told analysts to expect a low-90s combined ratio outcome over time. Watch whether Q1 prints in the low 80s (consistent with Arch's historical pattern of mild Q1 strength) or pushes into the mid-80s, signalling the cycle-down compression is arriving faster than expected.
Capital return cadence. With management's tone shifted from offensive to measured, Q1 buyback dollars vs. the Q3 $732M pace will be the cleanest test of whether the cautious posture translates into actual capital retention.
Standalone MidCorp disclosure. Three quarters of asking; still no standalone loss ratio number. Watch whether the FY2025 10-K supplemental disclosures finally quantify the convergence or whether the gap remains permanently embedded inside the consolidated print.
