Arch Capital Group Ltd. (ACGL) - Canvas Business Model: Value Propositions

Highly diversified risk portfolio, stabilizing earnings across market cycles

The core value Arch Capital Group Ltd. offers is a highly diversified underwriting platform-Insurance, Reinsurance, and Mortgage Insurance-that smooths out the inevitable volatility of the risk business. This approach delivers superior, stable returns by allowing capital to be dynamically allocated to the hardest (most profitable) markets. The proof is in the underwriting results: for the third quarter of 2025, the consolidated combined ratio (a key measure of underwriting profitability where a number below 100% means a profit) was an exceptional 79.8%.

This translates directly into shareholder value. For Q3 2025, the company delivered after-tax operating income of $1.0 billion, representing an 18.5% annualized operating return on average common equity. That's a strong signal of cycle management at work.

• Underwriting income rose 62% to $871 million in Q3 2025.
• The combined ratio excluding catastrophes was still a strong 80.5%.
• Net income available to common shareholders reached $1.3 billion.

Specialty P&C capacity for complex, hard-to-place risks

Arch Capital Group Ltd. is a market-maker in specialty property and casualty (P&C) risks, providing capacity for complex, unique exposures that standard carriers avoid. This focus on specialty lines allows for higher pricing power and better risk-adjusted returns. In the Insurance segment, gross premiums written (GPW) rose 9.7% in the third quarter of 2025, reflecting successful integration of the MCE Acquisition and strong pricing.

The Reinsurance segment is a major profit driver in this area, especially in property catastrophe and specialty lines. Here's the quick math: Reinsurance underwriting income soared to $482 million in Q3 2025, a massive increase of 223.5% year-over-year, and its combined ratio strengthened to an excellent 76.1%. This shows Arch is defintely capturing the upside in the hard reinsurance market.

Mortgage insurance capital relief for government-sponsored enterprises (GSEs)

The Mortgage segment provides a counter-cyclical and capital-efficient value proposition, primarily through private mortgage insurance (MI) and credit risk transfer (CRT) solutions. For US Government-Sponsored Enterprises (GSEs) like Fannie Mae and Freddie Mac, Arch's MI and CRT transactions provide essential credit protection and regulatory capital relief, effectively transferring risk from the taxpayer to the private market.

While the mortgage market saw some headwinds, with Q3 2025 gross premiums written dipping slightly to $330 million, the strategic value remains paramount. Arch is a key participant in GSE CRT programs and also provides Significant Risk Transfer (SRT) transactions to European banks, offering them regulatory capital relief on large portfolios of mortgage and SME loans.

Efficient use of third-party capital to reduce volatility and grow fee income

Arch Capital Group Ltd. uses its underwriting expertise to manage capital from third-party investors, primarily through Insurance-Linked Securities (ILS) and other structured reinsurance vehicles. This strategy is a two-fold value proposition: it reduces Arch's own balance sheet volatility by offloading peak risks, and it generates stable, fee-based income from managing that capital.

The dynamic capital management is evident in how the firm allocates and returns capital. In the third quarter of 2025 alone, Arch repurchased approximately $732 million of its common stock, demonstrating a commitment to capital efficiency and shareholder returns. The use of vehicles like Bellemeade Re, a mortgage insurance-linked notes program, shows a continuous effort to optimize capital structure by transferring risk to the capital markets.

Financial security and timely claims payment based on strong ratings

For clients and brokers, the ultimate value proposition is Arch Capital Group Ltd.'s financial strength to pay claims, especially after major loss events. This financial security is validated by its strong credit ratings from major agencies, which are paramount in the insurance and reinsurance world.

As of late 2025, Arch's key operating subsidiaries maintain superior financial strength ratings, underscoring their ability to honor their obligations. The company's total capitalization stood at approximately $26.4 billion as of September 30, 2025.

Rating Agency	Financial Strength Rating (FSR)	Outlook
S&P Global Ratings	AA-	Stable
A.M. Best	A+ (Superior)	Stable
Moody's	A1	Stable

This strong capital base and rating profile ensure that Arch is a reliable counterparty for its clients, whether they are a large corporation seeking specialty insurance or a global reinsurance buyer.

Arch Capital Group Ltd. (ACGL) - Canvas Business Model: Customer Relationships

High-touch, long-term relationships with key global brokers and ceding companies

Arch Capital Group Ltd. maintains a highly personal and strategic relationship model with its distribution partners-the global brokers and ceding companies (insurers who transfer risk). This isn't a transactional, low-touch model; it's built on deep, long-term engagement, which is essential for placing complex specialty insurance and reinsurance risks.

We don't sell policies directly to the public. Instead, our focus is on supporting these third-party partners who distribute our products. To ensure quality and transparency, we provide them with detailed online resources, including guidance on Product Governance and Fair Value Assessments, which helps them meet regulatory standards and deliver better outcomes to the end policyholder. This high-touch approach helps drive our Insurance segment's growth, which saw a 9.7% increase in gross premiums written in the 2025 third quarter, reflecting the strength of these distribution channels.

Dedicated underwriting teams providing customized risk solutions

The core of the relationship is the expertise we bring to the table. Our underwriters and risk analysts are not just quoting prices; they are highly skilled professionals who possess deep industry knowledge. This allows us to move beyond standard products and provide truly tailored insurance solutions that address the nuanced risk management needs of our clients.

This dedication to customized risk assessment is what differentiates us in the specialty markets. It's a consultative relationship, not a simple vendor-client one. Our disciplined underwriting approach is a hallmark of our performance, helping us achieve a consolidated combined ratio of 79.8% in the third quarter of 2025.

Direct engagement with GSEs (Fannie Mae, Freddie Mac) in mortgage segment

In the Mortgage segment, our customer relationship is direct, high-level, and regulatory-focused, primarily with Government-Sponsored Enterprises (GSEs) like Fannie Mae and Freddie Mac. We are a leading provider of U.S. mortgage insurance and a key participant in their mortgage Credit Risk Transfer (CRT) programs, a relationship we've maintained since their inception in 2013. This relationship involves continuous, direct engagement as an investor and advisor in various structures and transactions.

This direct channel with the GSEs is critical for the scale of our mortgage business. Even with a slight decline in gross premiums written in the mortgage segment by 2.7% in Q3 2025, reflecting a market slowdown, the underlying quality remains strong, with better-than-expected cure rates contributing to favorable prior-year loss reserve development.

Investor relations for third-party capital partners, focusing on transparency

A significant customer group is our third-party capital partners, who invest in our reinsurance vehicles. For them, the relationship is managed through a robust Investor Relations framework that prioritizes transparency and consistent communication. We treat this capital base as a strategic resource.

We provide regular, detailed financial supplements and host webcasts for our quarterly earnings, like the one for Q3 2025, to keep these partners fully informed. Our total capital stood at approximately $26.4 billion as of September 30, 2025, which underscores the importance of maintaining an open, high-trust relationship with all capital providers, including our common shareholders for whom we repurchased approximately $732 million of common stock in Q3 2025.

Customer Segment	Primary Relationship Type	Key 2025 Q3 Metric Impact
Global Brokers & Ceding Companies	High-Touch, Consultative Partnership	Insurance Segment GPW up 9.7%
GSEs (Fannie Mae, Freddie Mac)	Direct, Strategic, Regulatory-Focused	Mortgage Segment GPW down 2.7%
Third-Party Capital Partners	Transparent Investor Relations	Total Capital at $26.4 billion

Digital portals for efficient policy administration in certain segments

While the front-end relationship is high-touch with brokers, the back-end is supported by efficient digital tools. We use technology to streamline policy administration and claims processing, providing a self-service component to our partners. This hybrid model allows our underwriting teams to focus on complex risk selection-the value-add-while digital channels handle the volume and speed of administrative tasks.

We defintely provide online resources and guidance for our distributors and brokers, which is a form of self-service support for compliance and operational efficiency. This focus on operational efficiency is part of how we manage costs, even as our underwriting expense ratio rose slightly to 34.4% in the 2025 third quarter, partly due to acquisition-related costs.

The relationship strategy is simple: high-value service for complex risk, high-efficiency tools for routine work.

Arch Capital Group Ltd. (ACGL) - Canvas Business Model: Channels

You're looking at Arch Capital Group Ltd.'s channels, and what you need is a clear map of how this $26.4 billion capital powerhouse actually gets its specialty products to market. The takeaway is that Arch employs a highly diversified, multi-channel strategy-using traditional brokers for scale, direct relationships for complex risks, and proprietary digital platforms and capital markets vehicles for efficiency and risk transfer. It's a classic three-pillar approach: Insurance, Reinsurance, and Mortgage Insurance, each with its own distinct distribution engine.

Global insurance and reinsurance brokerage houses (primary distribution)

The vast majority of Arch's Insurance and Reinsurance business flows through the world's major global insurance and reinsurance brokers. Think of these brokers as your primary sales force, giving Arch immediate, worldwide reach without the massive overhead of a fully direct sales model. This channel is defintely the engine for the Reinsurance segment, which operates in most major global insurance centers, offering treaty and facultative property and casualty reinsurance.

For the Insurance segment, products move through a network of licensed independent producers and brokers. This is how Arch distributes a wide range of specialty risk solutions globally from its operations in North America, Europe, and Australia. The relationship is collaborative, not adversarial; Arch works closely with its brokers and insureds to craft solutions for complex risks.

Direct relationships with large corporate clients for specialty insurance

For the most complex, hard-to-place risks, a direct channel is often the most efficient. Arch Insurance maintains direct relationships with large corporations, professional firms, and financial institutions, particularly for excess and specialty coverage. For example, Arch Insurance Bermuda directly underwrites Specialty Casualty, Executive Assurance, and Professional Liability on an excess basis for large commercial and financial companies worldwide. This direct access allows for superior underwriting control and customization on high-value policies.

In the U.S., Arch also utilizes specialized affiliates like Arch Underwriters Inc. (AUI) to manage and distribute certain programs, such as Middle Market Commercial and Entertainment products, which acts as a hybrid channel combining agency distribution with direct underwriting oversight.

Mortgage insurance distributed directly to lenders and GSEs

The Mortgage segment, Arch MI, operates a highly focused, technology-driven distribution model centered on the U.S. housing finance system. The channel is essentially a direct-to-business (B2B) model, providing private mortgage insurance (MI) directly to mortgage lenders and the Government-Sponsored Enterprises (GSEs)-Fannie Mae and Freddie Mac.

This distribution is facilitated by proprietary digital platforms, making the process fast and integrated. Here's the quick math on their digital tools:

• RateStar: This is Arch MI's preferred risk-based MI pricing platform, allowing lenders to get quotes instantly.
• CONNECT: Lenders use this secure platform to order MI and service their policies.

Arch MI is also a leading participant in the GSEs' Credit Risk Transfer (CRT) reinsurance transactions, continuously participating in these programs since their inception in 2013. This dual-pronged approach-insuring loans for lenders and reinsuring risk for the GSEs-is a key competitive advantage.

Arch Capital Management's proprietary funds and sidecars for capital markets access

Arch has a sophisticated channel to bring third-party capital (investor money) directly into its reinsurance business, which is a form of capital management (Insurance-Linked Securities, or ILS). This is a crucial channel for managing risk aggregation and increasing underwriting capacity without diluting shareholder equity.

The primary platform for this is Arch Fund Management, established in Bermuda in 2025 to consolidate its third-party capital offerings. The main vehicle is the Voussoir Re Ltd. sidecar, a collateralized reinsurance special purpose insurer (SPI). This sidecar issues preferred shares, such as the Series 2025-3 preferred shares issued in March 2025, to institutional investors, effectively channeling investor funds to back Arch's reinsurance risks, primarily in the property catastrophe arena.

Regional offices worldwide to service local market needs

While technology and brokers handle the transaction volume, Arch's physical presence is critical for local underwriting expertise and claims service. As of early 2025, Arch Capital Group operates globally from more than 60 offices across North America, Europe, Asia, and Australia. This network ensures that the specialty underwriting teams have the local knowledge to price and manage risks effectively in diverse regulatory and market environments.

To be fair, the distribution mix is always shifting based on market cycles; if reinsurance rates spike, Arch can quickly deploy more capital through its broker and sidecar channels. If competition heats up in a specialty line, they can lean on their direct relationships and regional offices to maintain margin.

2025 Key Financial Metric (Q3 & FY Forecast)	Value/Amount	Context/Channel Relevance
After-Tax Operating Income (Q3 2025)	$1.0 billion	Indicates strong profitability across all three underwriting channels (Insurance, Reinsurance, Mortgage).
Consolidated Combined Ratio (Q3 2025)	79.8%	A measure of underwriting efficiency; a sub-100% ratio means the core insurance/reinsurance channels are profitable.
Book Value Per Common Share (Sept 30, 2025)	$62.32	Reflects shareholder value growth, supported by disciplined underwriting across all distribution channels.
Estimated Full-Year 2025 Adjusted EPS	$8.42	Analyst consensus forecast for the full fiscal year, demonstrating expected strong performance from all segments.
Total Capital (Sept 30, 2025)	$26.4 billion	The financial strength underpinning the capacity offered through all broker, direct, and capital markets channels.

Your next step is to map the premium volume growth from the Q4 2025 report against these specific channels to see which one is driving the most near-term growth.

Arch Capital Group Ltd. (ACGL) - Canvas Business Model: Customer Segments

You're looking at Arch Capital Group Ltd. (ACGL), and the first thing to grasp is that their customer base is not a single, monolithic group. It's a highly specialized, three-pronged attack across Insurance, Reinsurance, and Mortgage. This diversification is key to their stability, especially when one market softens.

In short, Arch Capital Group Ltd. targets sophisticated entities-other insurance companies, large corporations, and institutional investors-who need to offload or transfer massive, complex risks. The total trailing twelve-month (TTM) revenue as of September 30, 2025, sat at approximately $19.543 billion, which shows the scale of the risk they are taking on behalf of these customers. [cite: 6 in first search]

Global insurance and reinsurance companies (ceding companies)

This segment represents the core of their Reinsurance business. These customers are other primary insurers-like State Farm or Allstate-who transfer a portion of their own risk portfolio to Arch Capital Group Ltd. to manage their capital and exposure to large, catastrophic events (like hurricanes or major earthquakes). They are the ceding companies (the ones ceding, or giving up, the risk).

The Reinsurance segment is a major revenue driver, though it saw a pullback in Q3 2025 due to disciplined underwriting. Gross premiums written (GWP) for the Reinsurance segment in the second quarter of 2025 were about $3.2 billion, but GWP then fell 9.0% in the third quarter of 2025 as Arch Capital Group Ltd. chose to walk away from less-attractive specialty line transactions.

• Primary Need: Catastrophe protection and capital relief.
• Key Lines: Property catastrophe, casualty, marine, and aviation.
• 2025 Trend: Lower GWP in Q3 2025 reflects a refusal to chase lower pricing.

Large commercial and industrial enterprises seeking specialty P&C coverage

These customers are the direct clients of the Insurance segment, which focuses on specialty property and casualty (P&C) lines-the complex, non-standard risks that mass-market insurers avoid. Think of a major construction firm needing liability coverage for a skyscraper project, or a hospital system needing medical professional liability (malpractice) insurance.

This segment has been a clear growth engine, fueled partly by the acquisition of the U.S. MidCorp and Entertainment insurance businesses from Allianz. The Insurance segment's GWP in Q2 2025 was approximately $2.7 billion, and it continued a strong trajectory with GWP increasing 9.7% in Q3 2025. [cite: 4 in first search, 3 in first search]

Customer Type	Example Coverage	Q3 2025 GWP Growth
Large Commercial/Industrial	Excess casualty, Directors' & Officers' (D&O) liability	9.7% increase [cite: 3 in first search]
Healthcare Systems	Medical professional liability, general liability
Specialty Programs	Commercial automobile, inland marine

Mortgage lenders and financial institutions requiring credit risk transfer

This is the customer base for the Mortgage segment, primarily focused on providing private mortgage insurance (MI) in the U.S. and internationally. Their direct customers are mortgage lenders (like banks and non-bank originators) who need to protect themselves against borrower default risk, especially on low-down-payment loans, to comply with capital requirements (Private Mortgage Insurer Eligibility Requirements, or PMIERs). The Mortgage segment's GWP in Q2 2025 was about $323 million, though it declined 2.7% in Q3 2025 due to lower U.S. premium volume. [cite: 4 in first search, 8 in first search]

The key for these customers is efficient credit risk transfer (CRT). Arch Capital Group Ltd. provides them with a capital cushion, allowing them to originate more mortgages while managing regulatory requirements.

High-net-worth individuals and small businesses (indirectly via primary insurers)

While Arch Capital Group Ltd. doesn't typically sell policies directly to a homeowner or a small business owner, these are the ultimate insured parties whose risks they assume. This relationship is indirect, flowing through the primary insurers that are Arch Capital Group Ltd.'s direct customers in the Insurance and Reinsurance segments.

For example, a small business buying a commercial auto policy from a primary insurer is ultimately covered by Arch Capital Group Ltd. if that primary insurer has a reinsurance treaty with them. This indirect exposure is a significant part of the overall risk pool, even if the transaction is B2B (business-to-business).

Institutional investors (pension funds, sovereign wealth) seeking uncorrelated returns

This is the capital markets customer base, which is distinct from the traditional insurance customers. These investors-pension funds, sovereign wealth funds, and specialist insurance-linked securities (ILS) funds-provide capital to Arch Capital Group Ltd.'s risk transfer vehicles, like Bellemeade Re, in exchange for returns that are uncorrelated (meaning they don't move in tandem) with the broader stock or bond markets.

Here's the quick math: Arch Capital Group Ltd. recently closed the Bellemeade Re 2025-1 Ltd. issuance in November 2025, securing $199.3 million in capital markets backed mortgage reinsurance from these institutional investors. This capital acts as collateral to cover potential mortgage losses, offering the investors a fixed return for taking on that specific credit risk. This is a defintely smart way to utilize third-party capital without it sitting on their balance sheet.

Arch Capital Group Ltd. (ACGL) - Canvas Business Model: Cost Structure

Arch Capital Group Ltd.'s cost structure is fundamentally a function of its underwriting risk and its strategic push for efficiency, but the single largest driver of cost is always claims, or net losses. For the first nine months of 2025, the company's cost profile was clearly impacted by significant catastrophe events, even as its core underwriting expenses remained tightly managed.

You need to see the cost structure not just as a set of numbers, but as a reflection of the company's disciplined underwriting culture-they spend money to get the right risk, not just any risk. This cost discipline is visible in the consistently low combined ratio (a key measure of underwriting profitability) excluding major catastrophes and prior-year reserve releases, which hovered around 80.8% across the first three quarters of 2025. That's a very strong number.

Net losses and loss adjustment expenses (largest component)

This is the dominant and most volatile cost component for any insurer and reinsurer, covering the actual claims paid and the expense of investigating and settling those claims. While Arch Capital Group is known for its cycle management, 2025 saw some near-term volatility due to specific events.

The first half of the year was hit hard by the California wildfires, which drove the pre-tax current accident year catastrophic losses (net of reinsurance) to $547 million in the first quarter alone. This is the kind of near-term risk you must map. However, the third quarter was relatively quiet, with catastrophe losses dropping to just $72 million, demonstrating the segment's natural variability. On the positive side, the company continued to benefit from strong prior-year reserve development (releasing reserves previously set aside for claims that turned out to be lower than expected), totaling $409 million across the first three quarters of 2025.

Cost Component (Pre-Tax, Net of Reinsurance)	Q1 2025 (USD millions)	Q2 2025 (USD millions)	Q3 2025 (USD millions)	Q1-Q3 2025 Total (USD millions)
Current Accident Year Catastrophic Losses	$547	$154	$72	$773
Favorable Prior Year Loss Reserve Development	$167	$139	$103	$409

Policy acquisition costs (broker commissions and premium taxes)

Policy acquisition costs-the commissions paid to brokers and agents for bringing in business, plus premium taxes-are a major variable cost tied directly to premium volume. Arch Capital Group's strategy is to grow premiums while keeping this cost ratio stable or improving it, which they have largely done through their recent acquisitions and organic growth.

The underwriting expense ratio, which includes both acquisition costs and general administrative costs, was tightly controlled, averaging around 33.8% for the Insurance segment across the first three quarters of 2025. The consolidated underwriting expense ratio for Q3 2025 was 28.4%. This efficiency is partly a result of the 2024 acquisition of the U.S. middle market and entertainment businesses, which added premium volume without a proportional increase in operating expenses, leading to a 40 basis-point reduction in the other operating expense ratio in Q2 2025.

General and administrative expenses (salaries, IT, office costs)

These are the fixed and semi-variable costs that keep the lights on and the business running, including salaries, rent, and technology spend. Arch Capital Group is not a low-cost volume player; it is an underwriting-focused business, so it invests in top-tier talent and sophisticated systems. This is a cost center, but it's also a key strategic resource.

The company is seeing some operational leverage (increased premium without equal cost increase) from integrating its acquired businesses. The reduction in the other operating expense ratio in Q2 2025, partly due to leveraging existing IT and management infrastructure, shows this. You're seeing strategic cost containment, not just cost cutting.

Interest expense on debt and preferred shares

As a financially-leveraged entity, Arch Capital Group has costs associated with its debt and hybrid capital instruments. The company's long-term debt and capital lease obligation stood at approximately $2.73 billion as of September 2025, which is a manageable amount given its equity base.

The interest expense on this debt for the third quarter of 2025 was reported as $37 million. Additionally, the company is committed to paying dividends on its preferred shares, such as the Series F and Series G Non-Cumulative Preferred Shares, which carry dividend rates of 5.45% and 4.55%, respectively, as of early 2025. These are fixed financing costs that must be serviced regardless of underwriting performance.

Significant investment in underwriting talent and technology infrastructure

This is where Arch Capital Group's cost structure reveals its long-term strategy. The company views its investment in people and tech as a competitive necessity, not just an expense.

The costs here are embedded in the general and administrative expenses, but the strategic intent is clear:

• Advanced Analytics: Maintain a competitive edge through advanced analytics capabilities, which is crucial for pricing complex risks accurately and managing its diversified portfolio.
• Strategic Tech Investments: The company has made investments in external technology platforms, specifically targeting 'Internet First Insurance Platforms' like The Guarantors and Reserv, showing a willingness to spend capital to stay current on distribution and risk modeling technology.
• Talent Integration: The integration of acquired businesses, like the MidCorp and entertainment unit, is a major cost in the near-term (integration costs) but a long-term investment in specialized underwriting talent and market access.

Finance: Track the combined ratio ex-cat and ex-prior year development quarterly; if it rises above 82.0% in Q4 2025, you defintely need to review the underlying acquisition and G&A spend for bloat.

Arch Capital Group Ltd. (ACGL) - Canvas Business Model: Revenue Streams

Arch Capital Group Ltd. (ACGL) generates its revenue primarily through a powerful combination of underwriting profits from its diversified insurance segments and a growing, high-quality investment portfolio. The core takeaway is that the vast majority of cash flow comes from Net Earned Premiums, but the stability and growth of Net Investment Income are defintely critical to overall profitability.

Your revenue streams are not just about volume; they're about the quality and predictability of the cash flow, and Arch Capital has built a model where underwriting and investing work in tandem. For the twelve months ending September 30, 2025, the company's total revenue was a substantial $19.543 billion.

Net Earned Premiums from P&C, Reinsurance, and Mortgage segments

Net Earned Premiums (NEP) represent the revenue generated from the portion of insurance and reinsurance coverage for which the risk period has expired. This is the largest and most foundational revenue stream for Arch Capital. The company's scale is significant, with Estimated 2025 Gross Written Premiums (GWP)-the total premiums before reinsurance ceded-projected to be around $19.5 billion, reflecting strong market pricing and new business opportunities, particularly in the Property and Casualty (P&C) segments.

The segmentation of these premiums shows where Arch Capital is prioritizing capital deployment. You can see the strength of the underwriting engine in the Q3 2025 Net Earned Premiums of $4.29 billion.

Segment	Q3 2025 Net Premiums Earned (NEP)	Q3 2025 Segment Growth (YoY)	Key Driver
Insurance (P&C)	$1.969 billion	11.6%	MCE Acquisition and rate increases.
Reinsurance	Not explicitly stated (Segment NEP grew 6.5%)	6.5%	Hard market conditions, rate changes, and new business.
Mortgage	$281 million (Q2 2025)	-9.0% (Q2 2025 YoY decline)	Lower U.S. monthly and single premium volume.

Net investment income from the managed portfolio

Net Investment Income (NII) is the predictable, recurring revenue generated from the company's substantial investment portfolio, primarily composed of fixed-income securities. With interest rates remaining elevated, this stream has become a significant and growing contributor to overall profit. The pre-tax NII for the third quarter of 2025 was $408 million, following a Q2 2025 result of $405 million.

Here's the quick math: just the Q2 and Q3 2025 NII alone totals $813 million, demonstrating the power of a large, high-quality asset base in a higher-rate environment. The NII growth is primarily a function of strong operating cash flows, which are then reinvested at higher yields, increasing the average invested assets.

Fee income from managing third-party capital vehicles (Arch Capital Management)

A more strategic, less volatile revenue component comes from Arch Capital Management (ACM), which manages third-party capital (capital provided by outside investors) in insurance-linked securities (ILS) and other specialty vehicles. This revenue is recorded as 'Equity in net income of investments accounted for using the equity method' and represents management and performance fees.

This fee-based income is valuable because it requires less of Arch Capital's own balance sheet capital, essentially allowing the company to earn a return on underwriting expertise. The income from this stream was $134 million in Q3 2025 and $162 million in Q2 2025.

• Q3 2025 Equity Method Income: $134 million
• Q2 2025 Equity Method Income: $162 million
• This stream helps diversify revenue away from pure underwriting risk.

Realized and unrealized gains on investments, though volatile

Realized and unrealized gains (or losses) on the investment portfolio provide the final, most volatile, but sometimes most significant, revenue component. These gains result from selling investments for a profit (realized) or from changes in the market value of investments still held (unrealized). This stream is highly dependent on financial market movements, especially for the company's equity securities and derivatives.

While you can't rely on it quarter-to-quarter, it can provide a major boost. For example, Arch Capital reported net realized gains of $210 million in Q3 2025, a solid increase from the Q3 2024 figure of $169 million. In the prior quarter, Q2 2025, net realized gains were even higher at $229 million.
