Key Points
• Durable earnings floor supported by a ~£6.0b contractual service margin (CSM) balance and recurring investment spreads, underpinning £1.0b of adjusted operating profit even during periods of softer new-business premiums.
• Conservative investment portfolio where core assets are predominantly investment-grade and secured, supported by substantial holdings of government bonds and cash.
• Solid credit profile with manageable leverage and healthy coverage, backed by ample total liquidity against a well-staggered debt maturity profile.
About Rothesay
Rothesay Limited (“Rothesay” or the “Group”) is the UK’s largest specialist pensions insurer, built to write bulk purchase annuities (BPAs): taking defined-benefit pension liabilities off corporate balance sheets via “buy-ins” and “buy-outs.” As of 31 December 2025, it manages £73.5b in assets, securing the pensions of around one million people and paying roughly £360m in benefits each month. We note that the financials throughout this article are for Rothesay Limited, the consolidated group, while the bonds covered later are issued by its wholly owned subsidiary, Rothesay Life PLC (Issuer). Accordingly, we view the credit quality of the issuer and group as broadly aligned.
Do note that Rothesay is a privately held entity that only reports its financials on a semi-annual basis (first half ending 30 June and for the full year ending 31 December). Ownership is concentrated and high-quality: GIC (Singapore’s sovereign wealth fund) holds 50.2%, and MassMutual (a private insurance company with AA+ credit ratings) holds 47.6%, with equal governance rights and a stated commitment to provide primary capital for material growth. We think these two deep-pocketed, long-term owners with no near-term exit incentive help mitigate the group’s status as a private company.
FY25 recap: a quiet year on top, a resilient one underneath
Two engines drive Rothesay’s result, and FY25 (ending 31 December 2025) is best read by taking each in turn.
The first is the insurance service result. When Rothesay writes a BPA, accounting rules require the expected profit to be deferred within the contractual service margin (CSM) and released gradually as insurance services are delivered over the life of the contract, which for pension annuities can span 20 to 40 years. Accordingly, earnings from this segment track the pace of CSM release rather than new business activity alone.
For FY25, the insurance service result declined 16.5% YoY to £581m from £696m in FY24, driven by three modest movements rather than any structural deterioration. The largest was a small reduction in its scheduled CSM release (-£36m), though we note this likely reflects timing effects rather than franchise erosion. We note that the net CSM balance grew slightly over the year from £5.9b to £6.0b, suggesting the pipeline of locked-in future earnings remains intact and is being steadily replenished. A slightly weaker experience margin (-£16m) and higher reinsurance costs as Rothesay transferred more longevity risk off its books (-£65m) account for the remainder. Overall, the insurance service result saw a slight step down, but the underlying picture is stable, as seen in the modest increase in CSM balance.
The second is the investment side, the more market-sensitive of the two engines and where FY25 diverged sharply from the prior year. Unlike the insurance service result, this segment moves with interest rates and credit spreads, resulting in potentially more volatile annual figures. What matters is the net position after asset and liability movements offset each other. In FY25, net insurance and investment results rose to £2.1b in FY25, up from £0.8b in FY24. The improvement largely reflects a more favourable rate and spreads in the UK Gilts environment in FY25 compared to FY24, when sharp increases in gilt yields generated larger adverse movements. Combined with the insurance service result, this carried pre-tax profit to £1.2b (FY24: £113m).
In our view, the composition matters more than the headline. Adjusted operating profit, which strips out volatile economic movements and is the more reliable measure of Rothesay’s underlying earning capacity, eased to £1.0b (FY24: £1.8b). This primarily reflects a weaker new business CSM additions (£5.2b for FY25 compared to £15.7b in FY24) following the deliberately lighter deal year. That said, we point to net CSM balance modest YoY growth, MCEV (Market Consistent Embedded Value) increase to £8.0b (FY24: £7.7b), and positive operating cash generation of £477m (FY24:- £113m). Together, we think FY25 saw more disciplined expansion, and the overall (in-force) insurance book remains solid.
Costs stayed contained. Operating expenses of £210m (2024: £84m) reflect investment in new platforms and lending but remain modest against £4.7b of insurance revenue; after tax, profit for the year was £902m (FY24: £81m).
Looking ahead, management seems cautiously optimistic, describing its 2026 new business pipeline as healthy, with £2b of new business already locked in, implying an annual run-rate of £8.0b, reflecting a recovery from FY25 slowdown. The market backdrop supports this: UK pensions are expected to continue de-risking transactions in 2026, and market volumes are projected to range £350–550b over the next decade, leaving a healthy runway for Rothesay.
Durable earnings floor underpinned by the release of CSM and excess returns on long-duration assets
Rothesay’s adjusted operating profit is more visible and stable than it might appear for an insurer of its scale, given that it rests on two largely contracted sources rather than solely depending on underwriting new deals each year.
First, as highlighted earlier, whenever Rothesay writes a BPA, the expected profit is not booked upfront but locked inside the CSM. This liability is then slowly released as income gradually over the lifetime of the contract, which for pension annuities can be 20 to 40 years. Think of it like a very long pipeline of pre-earned income. Every year, a portion of that locked-in profit flows through to the P&L — regardless of whether Rothesay writes a single new deal. As seen in Chart 1 below, the net CSM stood at £6b as of the end of 31 December 2025, with a long visible release schedule. With over £3.0b slated to be released beyond the decade, Rothesay’s net CSM provides a high-quality anchor to operating profit that is insulated from new-business underwriting swings.
Next, the group invests premiums into higher-yielding, long-dated assets (bonds primarily) matched against its long-dated pension liabilities, earning a spread between asset yields and the rates implicit in those liabilities. However, as adjusted operating profit strips out mark-to-market movements, this volatility does not flow through to the underlying earnings measure that we can focus on. What does flow through is the recurring, locked-in element of the spread, contributing to the stability of adjusted operating profit. Together with the CSM release, this is why Rothesay’s operating earnings hold up even when new business premiums and market conditions can be volatile. As seen in Chart 2 below, adjusted operating profit over the last four years has been solidly positive, and has ranged between £1.0b and £1.8b since FY23.
Looking ahead, with a large scheduled CSM released profile, underpinned by a net CSM balance that rose slightly YoY to £6.0b, both earnings volatility and uncertainty are materially reduced. While a pickup in new business premiums, with sensible margins, would be nice, we remain comfortable with Rothesay’s earnings capacity even in the event of softer 2026 new business volumes.

A high-quality investment portfolio anchors Rothesay’s asset base
At first glance, Rothesay’s balance sheet shows £124.5b of investments, but the figure that really matters is smaller. Around £51b reflects accounting gross-up from derivatives and financing transactions: mainly £39.4b of derivatives and about £11.5b of short-term financing positions, each matched by an offsetting liability and designed to be largely self-cancelling (see Table 1 below). Strip those out, and the core portfolio backing the pensions is £73.5b of bonds, secured loans, and cash. Given that this is the pool that carries the risk, our analysis will focus on this smaller figure.
These derivatives are hedges rather than speculative positions. Rothesay uses interest-rate, inflation and currency swaps to make its assets behave more like its long-dated pension liabilities. As a result, movements in asset values are largely offset by corresponding changes in liabilities. The positions appear large because accounting rules require them to be reported on a gross basis rather than netted. The one real consequence of running such a book is liquidity — when rates move sharply, Rothesay must post cash collateral quickly, which is why it deliberately holds around £37b of government bonds and cash that can be turned into cash at short notice.
The £73.5b that remains is high quality and well secured (look at chart 3 below for a full breakdown). By external agency ratings measure, roughly 85.7% is investment grade, with a 14% unrated portion and negligible sub-investment-grade holdings of £78m (~0.1% of the book). The unrated portion is not risky credit — it is Rothesay's mortgage and property lending, written at conservative loan-to-values (new lifetime LTV ~29%), which agencies simply do not rate. Applying Rothesay's internal ratings to these positions lifts the investment-grade share to ~97%, with more than half rated AAA or AA, consisting mainly of UK government bonds and high-grade corporate bonds.
We flag a portfolio risk for completeness. Beyond government bonds and plain corporate credit, Rothesay holds infrastructure debt, mortgage lending, and property-backed assets — less liquid instruments whose valuations rely on internal assumptions and cashflow modelling rather than observable market prices. These are predominantly Level 3 assets on the balance sheet, and their share grew year-on-year, which modestly increases valuation and assumption risk.
Overall, we take comfort in the conservatism of the portfolio: high credit quality, secured low-LTV lending, assets matched to liabilities, and a deep buffer of cash and government bonds. We note that a 1% move in benchmark interest rates shifts equity by under £0.9b, and a 1% widening in credit spreads by around £0.8b. Both are well covered by the group’s £5.4b of surplus capital, leaving a comfortable cushion even before accounting for the fact that, with assets and liabilities matched, Rothesay would not be forced to sell into a falling market. Looking forward, we expect the portfolio to remain defensively positioned and see neither a market shock nor a sudden collateral call as likely to threaten solvency.

Solid credit profile with decent coverage and strong capitalisation
Overall, Rothesay has a solid credit profile and is well-capitalised. Its Solvency II surplus stood at around £5.4b as of 31 December 2025, equivalent to a Solvency Capital Requirement (SCR) coverage of 246%, providing 146 percentage points of headroom against the regulatory threshold. As seen in Table 2 below, coverage has gradually eased over the last three years, reflecting new business written and interest-rate moves rather than any stress, and remains well above management’s target operating range of 140%-160%.
Leverage is moderate: total borrowings £2.7b represent roughly 30% of its own eligible funds. Liquidity is ample with cash of £277m as of 31 December 2025, backed by a £750m undrawn committed revolving credit facility, giving Rothesay a total available liquidity of £1.0b. The business is also self-funding: positive operating cash flow of £477m in FY25 provides another form of support for the group’s liquidity profile.
As seen in chart 4 below, Rothesay’s debt maturity profile is well staggered with no refinancing wall and only one near-term bond maturity–the £500m of Tier 2 notes due in July 2026. Refinancing risk appears limited given the modest maturity size, available liquidity, and Rothesay’s strong capital position.
Finally, Rothesay’s interest coverage (adjusted operating profit / annual gross interest on borrowings) ratio is healthy at 6.3x, although we note this represents a step down compared to FY24’s 11x. This reflects the normalisation of operating profit from an exceptionally strong 2024 rather than any rise in borrowing cost or leverage.

Overall, we think Rothesay has a solid investment-grade credit profile, being rated A2 (Moody’s) and A+ (Fitch). The group’s earnings combine a stable, contracted core that is the relatively predictable CSM release, with a more volatile investment return that moves with rates and spreads and anchors the group's debt servicing capacity. We also point to Rothesay’s modest leverage (~30%) and healthy interest coverage ratios (6.3x), alongside a well-spread-out debt maturity profile, that support its credit profile. Looking ahead, we expect Rothesay’s credit profile to remain stable.
Crucially, all of Rothesay's debt is subordinated and ranks behind policyholders, absorbing losses ahead of them. Investors should note two key structural risks. First, Tier 2 coupons will be deferred (on a cumulative basis) and principal repayment may be suspended if Rothesay breaches its SCR or if making payment would cause it to do so. We view this as remote given 246% SCR coverage and a ~£5.4b surplus. Second, Restricted Tier 1 (RT1) securities carry fully discretionary, non-cumulative coupons and can be written down if SCR coverage falls below a predefined trigger (~75% of SCR). While remote at current capitalisation, this is the key risk RT1 investors are compensated for.
Investors should also be mindful of extension risk. Unlike bank Tier 2, insurer Tier 2 receives no regulatory capital amortisation ahead of maturity under Solvency II, meaning Rothesay has no capital-driven incentive to call early. Any call decision is therefore economic rather than regulatory, subject to PRA approval, and bonds should be assessed on their reset economics rather than assumed to be called at the first opportunity.
In Table 3 above, we highlight a couple of Rothesay’s outstanding bonds for consideration: the bullet bonds offer yields-to-worst ranging from 5.56% (USD) to 6.21% (GBP), with 3.0 years and 8.0 years to call. Against comparable US/UK treasuries, we find an attractive yield spread of 130+bps. As seen in the Bloomberg chart below, against comparable public financial peers, these issues (turquoise and pink dots) provide a decent yield pickup. We also highlight one outstanding perpetual: this issue provides a yield-to-worst of 7.06%, with 8.98 years to call. We think this yield premium partly reflects Rothesay’s status as a private company, which results in less frequent public disclosure compared to its public peers.
Investors who are comfortable with lower reporting frequency over the year can consider these outstanding bonds for their attractive yield, backed by Rothesay’s solid credit profile.
