Underlying net income(1) of $1,047 million increased $31 million or 3% from prior year, driven by:

Business Group Highlights

Asset Management: A global leader in both public and alternative asset classes through MFS and SLC Management

Asset Management underlying net income of $350 million increased $6 million or 2% from prior year, driven by:

•MFS(1) down $1 million (down $3 million on a U.S. dollar basis): A decrease in net investment income mostly offset by higher fee income from higher average net assets ("ANA"). Pre-tax net operating profit margin(2) was 39.2% for Q3'25, compared to 40.5% in the prior year.

•SLC Management up $7 million: Higher net seed investment income and fee-related earnings. Fee-related earnings(2) increased 8% driven by capital raising partially offset by higher expenses. Fee-related earnings margin(2) was 26.0% for Q3'25, compared to 24.2% in the prior year.

Reported net income of $316 million decreased $328 million or 51% from prior year, driven by the prior year decrease in SLC Management's estimated acquisition-related liabilities(3).

Foreign exchange translation led to an increase of $3 million in underlying net income and reported net income, respectively.

Total AUM(2) at Q3'25 was $1,176 billion (Q3'24 - $1,103 billion), consisting of $917 billion (US$659 billion) in MFS (Q3'24 - $873 billion and US$645 billion, respectively) and $259 billion in SLC Management (Q3'24 - $230 billion). Total Asset Management net inflows of $4.0 billion in Q3'25 (Q3'24 - net outflows of $17.4 billion) reflected SLC Management net inflows of $5.2 billion (Q3'24 - net inflows of $1.7 billion) from capital raising, partially offset by MFS net outflows of $1.2 billion (US$0.9 billion) (Q3'24 - net outflows of $19.1 billion and US$14.0 billion, respectively) from retail net outflows reflecting continued uncertainty in equity markets mostly offset by institutional net inflows.

BentallGreenOak ("BGO") closed its inaugural Canadian Value-Add Real Estate Strategy fund during the third quarter, raising $247 million. This fund positions BGO to capitalize on growth opportunities in Canada’s top real estate sectors by offering a differentiated investment strategy, reflecting BGO’s deep roots and long-standing commitment to the Canadian real estate market. BGO also launched BGO DataCenters, its European Hyperscale investment and development platform, focused on delivering customized sustainable, hyperscale, and AI-optimized digital infrastructure across Europe, meeting growing demand in one of real estate’s fastest-growing sectors.

InfraRed Capital Partners entered into a definitive agreement to acquire Rogers Communications’ data centre business to expand its footprint in Canada’s digital infrastructure market, capitalizing on rising demand for secure and reliable data centre services.

Canada: A leader in health, wealth, and insurance

Canada underlying net income of $422 million increased $47 million or 13% from prior year, driven by:

•Asset management & wealth up $19 million: Improved credit experience and higher fee income driven by higher AUM reflecting market movements.

•Group - Health & Protection up $25 million: Business growth, favourable insurance experience, and improved credit experience.

•Individual - Protection up $3 million: Higher investment earnings.

•Lower earnings on surplus primarily reflecting lower net interest income from lower surplus asset balances and rates.

Reported net income of $414 million increased $32 million or 8% from prior year, driven by the increase in underlying net income and favourable ACMA impacts, partially offset by market-related impacts reflecting unfavourable real estate experience and less favourable interest rate impacts.

Canada's sales(4):

•Asset management gross flows & wealth sales of $4 billion were up 9%, driven by higher mutual fund sales in Individual Wealth and higher rollover volumes in Group Retirement Services ("GRS") reflecting strong member deposits, partially offset by lower defined benefit solution sales in GRS.

•Group - Health & Protection sales of $98 million were down 21%, reflecting timing of large case sales.

•Individual - Protection sales of $130 million were up 16%, driven by higher non-participating life sales and increases across SLFD(5) and third-party channels.

Sun Life Global Investments ("SLGI") marked its 15-year anniversary of helping Canadians grow and protect their wealth. SLGI launched its first ETF Series in Q3'25, providing investors and advisors with more ways to access the deep specialized portfolio management expertise of MFS, SLC Management, and Crescent Capital Group LP.

EARNINGS NEWS RELEASE Sun Life Financial Inc. Third Quarter 2025 3

In Individual Insurance, we maintained a market leadership position(1) for discrete Q2’25 and year-to-date, driven by strong performance in non-participating products, including critical illness, which grew 31% in Q3'25 compared to the prior year. We continue to transform our insurance business by increasing digital processes and automation, including enhancements to our Underwriting Decision Algorithm. These efforts have reduced underwriting cycle times by 30% since the start of the year, enabling faster decisions and a more seamless Client experience.

U.S.: A leader in health and benefits

U.S. underlying net income of US$107 million decreased US$54 million or 34% ($147 million decreased $72 million or 33%) from prior year, driven by:

•Group - Health & Protection down US$64 million: Reflecting lower Group Benefits and Dental results. Group Benefits results were driven by unfavourable medical stop-loss insurance experience and unfavourable long-term disability experience in employee benefits. Dental results were driven by higher utilization rates and the prior year impact of a retroactive premium payment.

•Individual - Protection up US$10 million: Improved credit experience and higher investment earnings.

Reported net income of US$72 million decreased US$178 million or 71% ($98 million decreased $241 million or 71%) from prior year, reflecting unfavourable ACMA impacts and the decrease in underlying net income, partially offset by market-related impacts driven by improved real estate experience.

Foreign exchange translation led to an increase of $1 million in underlying net income and reported net income, respectively.

U.S. group sales of US$273 million were up 25% ($375 million, up 25%), primarily driven by higher large case sales in employee benefits and higher Dental sales.

In Dental, our strong sales pipeline has produced several contract implementations and new contract wins during the quarter that will give more than 2.3 million new members access to the dental care and coverage they need.

In employee benefits, we expanded our Family Leave Insurance offering to three additional states. In total, Sun Life now offers family leave services to employers in 24 states through statutory and voluntary programs, representing more than 57% of the U.S. population.

Asia: A regional leader focused on fast-growing markets

Asia underlying net income of $226 million increased $56 million or 33% from prior year, driven by:

•Asset management & wealth up $1 million: In line with the prior year.

•Individual - Protection(2) up $55 million: Continued strong sales momentum and in-force business growth across most markets, favourable mortality experience in International, and higher contributions from our India joint venture, partially offset by unfavourable credit experience.

Reported net income of $373 million increased $341 million from prior year, driven by a gain from increased ownership interest in Bowtie, favourable ACMA impacts, and the increase in underlying net income. Market-related impacts were in line with prior year as improved interest rate impacts were mostly offset by unfavourable other market-related impacts and less favourable equity market impacts.

Foreign exchange translation led to an increase of $1 million in underlying net income and an increase of $4 million in reported net income.

Asia's sales(3):

•Individual sales of $857 million were up 39%, driven by higher sales in:

◦Hong Kong from growth across all channels;

◦International from the broker channel;

◦the Philippines from agency and bancassurance channels; and

◦Indonesia and India primarily from the bancassurance channel.

•Asset management gross flows & wealth sales of $2 billion were up 15%, driven by higher fixed income fund sales in India and Mandatory Provident Fund ("MPF") sales in Hong Kong, partially offset by lower money market and fixed income fund sales in the Philippines.

New business CSM of $322 million in Q3'25 was up from $267 million in the prior year, driven by higher sales and profit margins partially offset by unfavourable business mix in Hong Kong.

We are dedicated to empowering advisors with centralized resources and AI-powered support for routine tasks and queries. In Hong Kong, our new Advisor Workbench streamlines multiple applications into a single, efficient platform.

In Sun Life Philippines, we have been recognized as the top Million Dollar Round Table ("MDRT")(4) company in the country for 2025, with 444 advisors qualifying, affirming our leadership in the Philippine life insurance industry and our commitment to excellence through the Most Respected Advisor program.

Underlying net income by Business Types

Sun Life has a diversified mix of businesses and our earnings by business type supports the analysis of our results:

•Asset management & wealth(1): Sun Life’s asset management & wealth businesses generate fee income and/or spread on investment products.

•Group - Health & Protection: Group businesses provide health and protection benefits to employer and government plan members. The products generally have shorter-term coverage periods, and more frequent repricing. The revenues are driven by premiums for coverage provided as well as fee-based earnings (i.e., Administrative Services Only plans, and dental fees).

•Individual - Protection: Generally, individual protection businesses have a longer-term profitability profile and are more sensitive to experience trends. The premiums include a margin for providing protection and are invested to earn a return over the expected amounts required to fulfill insurance liabilities.

The following provides an overview of the business types in Sun Life's business segments/business groups:

(1)Effective Q1'25, the Wealth & asset management business type was renamed to Asset management & wealth.

Quarterly Comparison - Q3'25 vs. Q3'24

Underlying net income(1) of $1,047 million increased $31 million or 3%, driven by:

•Asset management & wealth(1) up $26 million: Improved credit experience and higher fee income from higher AUM in Canada, and higher net seed investment income in SLC Management.

•Corporate expenses & other(1)(2) $(6) million increase in net loss reflecting timing of strategic investment spend.

(1)Refer to section N - Non-IFRS Financial Measures in this document for a reconciliation between reported net income and underlying net income.

10 Sun Life Financial Inc. Third Quarter 2025 MANAGEMENT'S DISCUSSION AND ANALYSIS

Reported net income of $1,106 million decreased $242 million or 18%, driven by:

•The prior year decrease in SLC Management's estimated acquisition-related liabilities(1);

•Unfavourable ACMA(2) impacts; and

•Market-related impacts reflecting unfavourable other market-related impacts, primarily from Asia, and real estate experience(3), partially offset by favourable interest rate impacts; partially offset by

•A gain from increased ownership interest in Bowtie(4); and

•The increase in underlying net income.

Foreign exchange translation led to an increase of $5 million in underlying net income and an increase of $8 million in reported net income.

Underlying ROE was 18.3% and reported ROE was 19.3% (Q3'24 - 17.9% and 23.8%, respectively).

1.Market-related impacts

Market-related impacts represent the difference between actual versus expected market movements(5). Market-related impacts resulted in a decrease of $14 million to reported net income, reflecting unfavourable real estate experience partially offset by favourable equity market and interest rate impacts.

2.Assumption changes and management actions

The net impact of assumption changes and management actions was a decrease of $13 million to reported net income and includes methods and assumptions changes on insurance contracts as well as related impacts. These included unfavourable impacts from model refinements across all business groups, expense updates mainly in Asia, and policyholder behaviour updates in Canada, partially offset by favourable financial updates in Canada and Asia, and mortality updates in Canada. For additional details refer to "Assumption Changes and Management Actions by Type" in section E - Contractual Service Margin in this document.

3.Other adjustments

Other adjustments increased reported net income by $86 million, driven by:

•A gain from increased ownership interest in Bowtie; partially offset by

•DentaQuest acquisition, integration and restructuring costs and amortization of acquired intangible assets; and

•Changes in SLC Management's acquisition-related liabilities(6).

4.Experience-related items

In the third quarter of 2025, notable experience items included:

•Favourable mortality experience primarily in Asia and Canada;

•Unfavourable morbidity experience across U.S. Dental, U.S. medical stop-loss, and U.S. employee benefits, largely offset by favourable morbidity experience in Canada;

•Net credit was unfavourable primarily from Asia; and

•Other experience was favourable primarily from the U.S. and Canada.

5.Income taxes

The statutory tax rate is impacted by various tax items, such as lower taxes on income subject to tax in foreign jurisdictions, tax-exempt or low-taxed investment income, and other sustainable tax benefits.

The Q3'25 effective income tax rate(7) on underlying net income and reported net income was 19.4% and 18.0% respectively.

6.Impacts of foreign exchange translation

Foreign exchange translation led to an increase of $5 million in underlying net income and an increase of $8 million in reported net income.

(1)There were no changes in estimated future payments for options to purchase the remaining ownership interests of SLC Management affiliates in Q3’25 (Q3'24 - a decrease of $334 million).

(2)Assumption Changes and Management Actions ("ACMA").

(3)Real estate experience reflects the difference between the actual value of real estate investments compared to management's longer-term expected returns supporting insurance contract liabilities ("real estate experience").

(4)On July 15, 2025, we acquired an additional interest in Bowtie Life Insurance Company Limited ("Bowtie"), which increased our ownership interest, excluding dilution, by approximately 11% and resulted in a total ownership interest of 55.8%. Total consideration was cash of $55 million. Our previously held interest in Bowtie was remeasured to its fair value, which resulted in a gain of $176 million recognized in reported net income in Q3'25 ("gain from increased ownership interest in Bowtie"). For additional information, refer to Note 3 of our Interim Consolidated Financial Statements for the period ended September 30, 2025.

(5)Except for risk free rates which are based on current rates, expected market movements are based on our medium-term outlook which is reviewed annually.

(6)Amounts relate to acquisition costs for our SLC Management affiliates, BentallGreenOak, Crescent Capital Group LP and Advisors Asset Management, Inc, which include the unwinding of the discount for Other financial liabilities.

(7)Our effective income tax rate on reported net income is calculated using Total income (loss) before income taxes, as detailed in Note 9 in our
Interim Consolidated Financial Statements for the period ended September 30, 2025. Our effective income tax rate on underlying net income is calculated using pre-tax underlying net income, as detailed in section N - Non-IFRS Financial Measures in this document, and the associated income tax expense.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Third Quarter 2025 11

Year-to-Date Comparison - Q3'25 vs. Q3'24

Underlying net income of $3,107 million increased $216 million or 7%, driven by:

•Asset management & wealth up $105 million: Higher fee-related earnings from catch-up fees and strong performance of net seed investment income in SLC Management, and higher fee income in Canada and Asia driven by higher AUM, partially offset by a decease in net investment income in MFS(1).

•Group - Health & Protection up $10 million: Business growth and favourable insurance experience in Canada, and higher U.S. Dental results, were mostly offset by lower U.S. Group Benefits results primarily driven by unfavourable medical stop-loss insurance experience and less favourable long-term disability experience in employee benefits.

•Individual - Protection(2) up $94 million: Business growth and higher contributions from joint ventures in Asia, and higher investment earnings in Asia and Canada, partially offset by higher expenses primarily reflecting continued investments in the business, and unfavourable credit experience, in Asia.

•Corporate expenses & other(2) $7 million decrease in net loss primarily driven by timing of strategic investment spend, and lower incentive compensation, partially offset by lower investment income from lower surplus asset balances.

Reported net income of $2,750 million decreased $62 million or 2%, driven by:

•The prior year decrease in SLC Management's acquisition-related liabilities(3);

•Prior year gains on partial sale of ABSLAMC(4) and the early termination of a distribution agreement in Asset Management;

•An impairment charge of $61 million on a customer relationship intangible asset from the early termination of a U.S. group dental contract; and

•Unfavourable ACMA impacts; partially offset by

•The increase in underlying net income;

•A gain from increased ownership interest in Bowtie; and

•A prior year restructuring charge of $108 million in Corporate(5).

•Market-related impacts were in line with the prior year as favourable interest rate impacts and improved real estate experience were offset by unfavourable other market-related impacts driven primarily across Asia and Canada, and unfavourable equity market impacts.

Foreign exchange translation led to an increase of $53 million in underlying net income and an increase of $56 million in reported net income.

Underlying ROE was 17.8% and reported ROE was 15.8% (2024 - 17.2% and 16.8%, respectively).

1.Market-related impacts

Market-related impacts represent the difference between actual versus expected market movements(6). Market-related impacts resulted in a decrease of $202 million to reported net income, reflecting unfavourable real estate experience and unfavourable other market-related impacts primarily from Asia, partially offset by favourable interest rate impacts.

2.Assumption changes and management actions

The net impact of assumption changes and management actions was a decrease of $14 million to reported net income and includes methods and assumptions changes on insurance contracts as well as related impacts. These included various small enhancements for the first six months of 2025, and for additional details on Q3'25 ACMA, refer to "Assumption Changes and Management Actions by Type" in section E - Contractual Service Margin in this document.

3.Other adjustments

Other adjustments decreased reported net income by $141 million, driven by:

•DentaQuest acquisition, integration and restructuring costs and amortization of acquired intangible assets;

•An impairment charge of $61 million on a customer relationship intangible asset from the early termination of a U.S. group dental contract; and

•Changes in SLC Management's acquisition-related liabilities(7); partially offset by

•A gain from increased ownership interest in Bowtie.

(1)MFS Investment Management ("MFS").

(3)There were no changes in estimated future payments for options to purchase the remaining ownership interests of SLC Management affiliates in Q3’25 (Q3'24 - a decrease of $334 million).

(4)To meet regulatory obligations, on March 21, 2024, we sold 6.3% of our ownership interest in Aditya Birla Sun Life AMC Limited (“partial sale of ABSLAMC”), generating a gain of $84 million. As a result of this transaction, our ownership interest in ABSLAMC was reduced from 36.5% to 30.2% for gross proceeds of $136 million. Subsequently, on May 31, 2024, we sold an additional 0.2% of our ownership interest.

(5)A restructuring charge of $108 million (pre-tax $138 million) recorded in Q2'24 reflecting actions taken to improve financial discipline and productivity, consistent with our Client Impact Strategy, supporting our Medium-Term Financial Objective for underlying EPS growth ("prior year restructuring charge in Corporate"). We expect these actions to result in annual savings of approximately $200 million (pre-tax) by 2026.

(6)Except for risk free rates which are based on current rates, expected market movements are based on our medium-term outlook which is reviewed annually.

(7)Amounts relate to acquisition costs for our SLC Management affiliates, BentallGreenOak, Crescent Capital Group LP and Advisors Asset Management, Inc, which include the unwinding of the discount for Other financial liabilities.

12 Sun Life Financial Inc. Third Quarter 2025 MANAGEMENT'S DISCUSSION AND ANALYSIS

4. Experience-related items

Notable experience items in the current year included:

•Favourable mortality experience primarily in Asia and Canada;

•Unfavourable morbidity experience in U.S. Dental and U.S. medical stop-loss, largely offset by favourable morbidity experience in Canada;

•Unfavourable expense experience largely in the U.S., Canada and Asia; and

•Other experience was favourable primarily from the U.S., Canada, and Asia.

5.Income taxes

The statutory tax rate is impacted by various items, such as lower taxes on income subject to tax in foreign jurisdictions, tax-exempt or low-taxed investment income, and other sustainable tax benefits.

Global Minimum Tax ("GMT") rules applied to Sun Life effective January 1, 2024:

•Canadian GMT legislation requires the ultimate parent entity of a group to pay top-up tax, on a jurisdiction-by-jurisdiction basis, on profits of its subsidiaries that are taxed below 15%. Some jurisdictions have enacted a Qualifying Domestic Minimum Top-Up Tax ("QDMTT") which requires the GMT top-up tax to be paid locally rather than to the ultimate parent entity's jurisdiction.

•In response to the GMT rules, Bermuda enacted a Corporate Income Tax ("CIT") regime, including a corporate income tax rate of 15%, which applies to Sun Life effective January 1, 2025. The Bermuda CIT is not a QDMTT for the purposes of GMT. Top-up tax may still be payable by the ultimate parent entity under the Income Inclusion Rule ("IIR"), depending on the effective tax rate in Bermuda.

•Other Sun Life subsidiaries that are currently subject to a statutory tax rate or to a tax regime that could result in taxing profits at a rate below 15% include those in Hong Kong and Ireland, which have both enacted a QDMTT.

•For additional information, refer to Note 9 in our Interim Consolidated Financial Statements for the period ended September 30, 2025.

The effective income tax rate(1) for the current year on underlying net income and reported net income was 18.8% and 19.1%, respectively.

6. Impacts of foreign exchange translation

Foreign exchange translation led to an increase of $53 million in underlying net income and an increase of $56 million in reported net income.

(1)Our effective income tax rate on reported net income is calculated using Total income (loss) before income taxes, as detailed in Note 9 in our
Interim Consolidated Financial Statements for the period ended September 30, 2025. Our effective income tax rate on underlying net income is calculated using pre-tax underlying net income, as detailed in section N - Non-IFRS Financial Measures in this document, and the associated income tax expense.

Total asset management gross flows & wealth sales increased $20.2 billion or 48% from prior year ($19.7 billion(1) or 47%(1), excluding foreign exchange translation).

•Asset Management gross flows increased $19.1 billion(1) or 53%(1), from higher gross flows in MFS and SLC Management.

•Canada asset management gross flows & wealth sales increased $0.3 billion or 9%, driven by higher mutual fund sales in Individual Wealth and higher rollover volumes in Group Retirement Services ("GRS") reflecting strong member deposits, partially offset by lower defined benefit solution sales in GRS.

•Asia asset management gross flows & wealth sales increased $0.3 billion(1) or 17%(1), driven by higher fixed income fund sales in India and Mandatory Provident Fund ("MPF") sales in Hong Kong, partially offset by lower money market and fixed income fund sales in the Philippines.

Total group health & protection sales increased $53 million or 12% from prior year ($50 million(1) or 11%(1), excluding foreign exchange translation).

•Canada group sales decreased $26 million or 21%, reflecting timing of large case sales.

•U.S. group sales increased $72 million(1) or 25%(1), primarily driven by higher large case sales in employee benefits and higher Dental sales.

Total individual protection sales increased $257 million or 35% from prior year ($254 million(1) or 35%(1), excluding foreign exchange translation).

•Canada individual sales increased $18 million or 16%, driven by higher non-participating life sales and increases across SLFD(2) and third-party channels.

◦Hong Kong from growth across all channels;

◦International from the broker channel;

◦the Philippines from agency and bancassurance channels; and

◦Indonesia and India primarily from the bancassurance channel.

New business CSM represents growth derived from sales activity in the period. The impact of new insurance business drove a $446 million increase in CSM, compared to new business CSM of $383 million in the prior year, driven by strong profit margins and sales partially offset by unfavourable business mix in Asia, primarily in Hong Kong.

Total CSM ended Q3'25 at $14.4 billion, an increase of $1.0 billion or 8% for the first nine months of 2025.

•Organic CSM movement was driven by the impact of new insurance business, reflecting strong profit margins and sales in Asia, primarily in Hong Kong, and individual protection sales in Canada.

•Unfavourable insurance experience in Canada partially offset by Asia.

•Favourable impact of markets and other driven by interest and equity experience.

•Impact of change in assumptions include the favourable impact of mortality updates in Canada and model refinements across all business groups, partially offset by unfavourable policyholder behaviour and expense updates.

•Unfavourable currency impacts in Asia and the U.S.

16 Sun Life Financial Inc. Third Quarter 2025 MANAGEMENT'S DISCUSSION AND ANALYSIS

Assumption Changes and Management Actions by Type

The impact on CSM of ACMA is attributable to insurance contracts and related impacts under the general measurement approach ("GMA") and variable fee approach ("VFA"). For insurance contracts measured under the GMA, the impacts flow through the CSM at locked-in discount rates. For insurance contracts measured under the VFA, the impact flows through the CSM at current discount rates.

The following table sets out the impacts of ACMA on our reported net income and CSM in the third quarter of 2025.


As at September 30, 2025
($ millions)	Reported net income impacts (After-tax)(1)(2)	Deferred in CSM (Pre-tax)(2)(3)(4)	Comments
Mortality/morbidity	14	276	Updates to reflect mortality and morbidity experience in all jurisdictions. The largest item was a favourable mortality update mainly to Group Retirement Services and Individual Wealth in Canada.
Policyholder behaviour	(16)	(143)	Updates to reflect lapse and policyholder behaviour in all jurisdictions. The largest items were adverse lapse and policyholder behaviour in Individual Insurance in Canada and in Vietnam in Asia.
Expense	(29)	(86)	Updates to expenses in all jurisdictions.
Financial	48	4	Updates to various financial-related assumptions.
Modelling enhancement and other	(30)	88	Various enhancements and methodology changes. The largest items were the net favourable impacts of refinements in Hong Kong and International in Asia.
Total impact of change in assumptions	(13)	139

(1)In this document, the reported net income impact of ACMA is shown in aggregate for Net insurance service result and Net investment result, and excludes amounts attributable to participating policyholders.

(2)CSM is shown on a pre-tax basis as it reflects the changes in our insurance contract liabilities, while reported net income is shown on a post-tax basis to reflect the impact on capital.

(3)The impact of change in assumptions in the CSM rollforward of $119 million is comprised of $(6) million for the three months ended March 31, 2025 from various small enhancements, $(14) million for the three months ended June 30, 2025 from various small enhancements, and $139 million for the three months ended September 30, 2025, as referenced in the table above.

(4)Total impact of change in assumptions represents a non-IFRS financial measure for amounts deferred in CSM. For more details, see section

1. Life Insurance Capital Adequacy Test

The Office of the Superintendent of Financial Institutions has developed the regulatory capital framework referred to as the Life Insurance Capital Adequacy Test for Canada. LICAT measures the capital adequacy of an insurer using a risk-based approach and includes elements that contribute to financial strength through periods when an insurer is under stress as well as elements that contribute to policyholder and creditor protection wind-up.

SLF Inc. is a non-operating insurance company and is subject to the LICAT guideline. Sun Life Assurance, SLF Inc.'s principal operating life insurance subsidiary, is also subject to the LICAT guideline.

SLF Inc.'s LICAT ratio of 154% as at September 30, 2025 increased two percentage points compared to December 31, 2024, driven by organic capital generation, net of shareholder dividend payments, and subordinated debt issuance, mostly offset by share buybacks and M&A(1) activity.

Sun Life Assurance's LICAT ratio of 138% as at September 30, 2025 decreased eight percentage points compared to December 31, 2024, driven by organic capital generation, net of dividend payments to SLF Inc., M&A activity, and market impacts.

The Sun Life Assurance LICAT ratios in both periods are well above OSFI's supervisory ratio of 100% and regulatory minimum ratio of 90%.

2. Capital

Our total capital consists of subordinated debt and other capital instruments, CSM, equity in the participating account and total shareholders' equity which includes common shareholders' equity, preferred shares and other equity instruments, and non-controlling interests. As at September 30, 2025, our total capital was $47.8 billion, an increase of $1.9 billion compared to December 31, 2024. The increase to total capital included reported net income of $2,750 million, an increase of $1,040 million in CSM, the issuance of $1,000 million principal amount of Series 2025-1 Subordinated Unsecured 4.14% Fixed/Floating Debentures, which is detailed below, net unrealized gains on FVOCI assets of $241 million, and non-controlling interests of $221 million reflecting our increased ownership interest in Bowtie(1). This was partially offset by the payment of $1,465 million of dividends on common shares of SLF Inc. ("common shares"), a decrease of $1,315 million from the repurchase and cancellation of common shares, which is detailed below, and unfavourable impacts from foreign exchange translation of $590 million included in other comprehensive income (loss) ("OCI").

In Q3'25, organic capital generation(2) was $624 million, which measures the change in capital, net of dividends, above LICAT requirements excluding the impacts of markets and other non-recurring items. Organic capital generation was driven by growth in underlying net income and new business CSM.

Our capital and liquidity positions remain strong with a LICAT ratio of 154% at SLF Inc., a financial leverage ratio of 21.6%(2) and $2.1 billion in cash and other liquid assets(2) as at September 30, 2025 in SLF Inc.(3) (December 31, 2024 - $1.4 billion).

Capital Transactions

On June 30, 2025, 2,664,916 of the 4,982,669 Class A Non-cumulative Floating Rate Preferred Shares Series 9QR (the "Series 9QR Shares") were converted into Class A Non-Cumulative Rate Reset Preferred Shares Series 8R (the "Series 8R Shares") on a one-for-one basis and 1,400 of its 6,217,331 Series 8R Shares were converted into Series 9QR Shares on a one-for-one basis. As a result, as of June 30, 2025, SLF Inc. has 8,880,847 Series 8R Shares and 2,319,153 Series 9QR Shares issued and outstanding.

On September 11, 2025, SLF Inc. issued $1 billion principal amount of Series 2025-1 Subordinated Unsecured 4.14% Fixed/Floating Debentures due 2037. The net proceeds will be used for general corporate purposes, which may include supporting the acquisition of SLF Inc.'s remaining interests in the SLC Management affiliates BentallGreenOak and Crescent Capital Group LP, investments in subsidiaries, repayment of indebtedness and other strategic investments.

Normal Course Issuer Bids

On August 29, 2024, SLF Inc. commenced a normal course issuer bid, which was in effect until June 6, 2025 (the "2024 NCIB").

On June 4, 2025, SLF Inc. announced that OSFI and the Toronto Stock Exchange (“TSX”) had approved its previously announced early renewal of its normal course issuer bid. As of June 4, 2025, SLF Inc. had purchased on the TSX, other Canadian stock exchanges and/or alternative Canadian trading platforms 14,429,085 of the 15,000,000 common shares that it was authorized to repurchase under the 2024 NCIB. Under SLF Inc.'s renewed normal course issuer bid (the "2025 NCIB"), it is permitted to purchase up to 10,570,915 common shares, being equal to the remaining 570,915 common shares that it had not repurchased under the 2024 NCIB plus an additional 10,000,000 common shares. The 2025 NCIB commenced on June 9, 2025 and will continue until May 21, 2026 or such earlier date as SLF Inc. may determine. Any common shares purchased by SLF Inc. pursuant to the 2025 NCIB will be cancelled or used in connection with certain equity settled incentive arrangements.

Shares purchased and subsequently cancelled under both bids were as follows:

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Third Quarter 2025 21

Profitability

Quarterly Comparison - Q3'25 vs. Q3'24

Asset Management underlying net income of $350 million increased $6 million or 2%, driven by:

•MFS down $1 million (down $3 million on a U.S. dollar basis): A decrease in net investment income mostly offset by higher fee income from higher average net assets ("ANA"). Pre-tax net operating profit margin(1) was 39.2% for Q3'25, compared to 40.5% in the prior year.

•SLC Management up $7 million: Higher net seed investment income and fee-related earnings. Fee-related earnings(1) increased 8% driven by capital raising partially offset by higher expenses. Fee-related earnings margin(1) was 26.0% for Q3'25, compared to 24.2% in the prior year.

Reported net income of $316 million decreased $328 million or 51%, driven by the prior year decrease in SLC Management's estimated acquisition-related liabilities(2).

Foreign exchange translation led to an increase of $3 million in underlying net income and reported net income, respectively.

Year-to-Date Comparison - Q3'25 vs. Q3'24

Asset Management underlying net income of $1,001 million increased $68 million or 7% driven by:

•MFS up $1 million (down $16 million on a U.S. dollar basis): The impacts from favourable foreign exchange translation were offset by a decrease in net investment income.

•SLC Management up $67 million: Higher fee-related earnings and strong performance of net seed investment income. Fee-related earnings(1) increased 29% driven by strong capital raising and higher catch-up fees, partially offset by higher expenses.

Reported net income of $896 million decreased $306 million or 25%, driven by the prior year decrease in SLC Management's estimated acquisition related liabilities(2) , a prior year gain on the early termination of a distribution agreement, and market-related impacts in SLC Management, partially offset by the increase in underlying net income and fair value changes in MFS shares owned by management.

Foreign exchange translation led to an increase of $22 million in underlying net income and an increase of $26 million in reported net income.

Growth

Asset Management AUM of $1,175.8 billion increased $54.4 billion or 5% from December 31, 2024, driven by:

•Net asset value changes of $80.2 billion; partially offset by

•Net outflows of $20.4 billion; and

•Client distributions of $5.4 billion.

MFS' AUM increased US$52.8 billion or 9% from December 31, 2024, driven by:

•The increase in asset values from higher equity markets of US$76.1 billion partially offset by net outflows of US$23.3 billion.

In Q3'25, 66%, 25%, and 29% of MFS' U.S. retail mutual fund assets ranked in the top half of their Morningstar categories based on ten-, five- and three-year performance, respectively.

SLC Management's AUM increased $8.8 billion or 4% from December 31, 2024, driven by:

•Net inflows of $12.3 billion and asset value changes of $1.9 billion, partially offset by Client distributions of $5.4 billion.

•Net inflows were comprised of capital raising and Client contributions, totaling $24.2 billion, partially offset by outflows of $11.9 billion.

SLC Management's FE AUM increased $6.7 billion or 3% from December 31, 2024, driven by:

•Net inflows of $19.1 billion partially offset by Client distributions of $10.0 billion and asset value changes of $2.4 billion.

•Net inflows were comprised of capital deployment and Client contributions, totaling $28.7 billion, partially offset by outflows of $9.6 billion.

Profitability

Quarterly Comparison - Q3'25 vs. Q3'24

Underlying net income of $422 million increased $47 million or 13%, driven by:

•Asset management & wealth up $19 million: Improved credit experience and higher fee income driven by higher AUM reflecting market movements.

•Group - Health & Protection up $25 million: Business growth, favourable insurance experience, and improved credit experience.

•Individual - Protection up $3 million: Higher investment earnings.

•Lower earnings on surplus primarily reflecting lower net interest income from lower surplus asset balances and rates.

Reported net income of $414 million increased $32 million or 8%, driven by the increase in underlying net income and favourable ACMA impacts, partially offset by market-related impacts reflecting unfavourable real estate experience and less favourable interest rate impacts.

Year-to-Date Comparison - Q3'25 vs. Q3'24

Underlying net income of $1,177 million increased $90 million or 8%, driven by:

•Asset management & wealth up $17 million: Higher fee income driven by higher AUM reflecting market movements, and improved credit experience, partially offset by lower investment earnings reflecting relatively lower yields on investment contracts.

•Group - Health & Protection up $57 million: Business growth and favourable insurance experience.

•Individual - Protection up $16 million: Higher investment earnings and favourable insurance experience.

•Lower earnings on surplus primarily reflecting lower net interest income from lower surplus asset balances and rates.

Reported net income of $1,095 million increased $131 million or 14% driven by the increase in underlying net income and favourable ACMA impacts. Market-related impacts were in line with the prior year as favourable interest rate impacts were mostly offset by unfavourable other market-related impacts.

Growth

Quarterly Comparison - Q3'25 vs. Q3'24

Canada's sales included:

•Asset management gross flows & wealth sales of $4.1 billion were up 9%, driven by higher mutual fund sales in Individual Wealth and higher rollover volumes in GRS reflecting strong member deposits, partially offset by lower defined benefit solution sales in GRS.

•Group - Health & Protection sales of $98 million were down 21%, reflecting timing of large case sales.

•Individual - Protection sales of $130 million were up 16%, driven by higher non-participating life sales and increases across SLFD and third-party channels.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Third Quarter 2025 23

Year-to-Date Comparison - Q3'25 vs. Q3'24

Profitability

Quarterly Comparison - Q3'25 vs. Q3'24

Underlying net income of US$107 million decreased US$54 million or 34%, driven by:

•Individual - Protection up US$10 million: Improved credit experience and higher investment earnings.

Reported net income of US$72 million decreased US$178 million or 71%, reflecting unfavourable ACMA impacts and the decrease in underlying net income, partially offset by market-related impacts driven by improved real estate experience.

Foreign exchange translation led to an increase of $1 million in underlying net income and reported net income, respectively.

Year-to-Date Comparison - Q3'25 vs. Q3'24

Underlying net income of US$401 million decreased US$50 million or 11%, driven by:

•Group - Health & Protection down US$48 million: Lower Group Benefits results driven by unfavourable medical stop-loss insurance experience and less favourable long-term disability experience in employee benefits, partially offset by higher Dental results. Higher Dental results were driven by Medicaid repricing, prior year impacts, and higher fee income and management actions, while results continue to reflect higher utilization rates.

•Individual - Protection down US$2 million: In line with the prior year.

Reported net income of US$275 million decreased US$137 million or 33%, driven by unfavourable ACMA impacts, the decline in underlying net income, and an impairment charge of US$45 million on a customer relationship intangible asset from the early termination of a U.S. group dental contract, partially offset by favourable market related impacts. Market-related impacts were driven by improved real-estate experience and favourable interest rate impacts, partially offset by unfavourable equity market impacts.

Foreign exchange translation led to an increase of $16 million in underlying net income and an increase of $13 million in reported net income.

Growth

Quarterly Comparison - Q3'25 vs. Q3'24

U.S. group sales of US$273 million were up 25%, primarily driven by higher large case sales in employee benefits and higher Dental sales.

Year-to-Date Comparison - Q3'25 vs. Q3'24

U.S. group sales of US$622 million were up 3%, primarily driven by higher large case sales in employee benefits and higher Dental sales, partially offset by lower medical stop-loss sales in Group Benefits reflecting pricing discipline in a competitive market.

Profitability

Quarterly Comparison - Q3'25 vs. Q3'24

Underlying net income of $226 million increased $56 million or 33%, driven by:

•Asset management & wealth up $1 million: In line with the prior year.

•Individual - Protection(1) up $55 million: Continued strong sales momentum and in-force business growth across most markets, favourable mortality experience in International, and higher contributions from our India joint venture, partially offset by unfavourable credit experience.

Reported net income of $373 million increased $341 million, driven by a gain from increased ownership interest in Bowtie, favourable ACMA impacts, and the increase in underlying net income. Market-related impacts were in line with prior year as improved interest rate impacts were mostly offset by unfavourable other market-related impacts and less favourable equity market impacts.

Foreign exchange translation led to an increase of $1 million in underlying net income and an increase of $4 million in reported net income.

Year-to-Date Comparison - Q3'25 vs. Q3'24

Underlying net income of $629 million increased $103 million or 20%, driven by:

•Asset management & wealth up $20 million: Higher fee income primarily driven by higher AUM reflecting market movements and net inflows.

•Individual - Protection(1) up $83 million: Continued strong sales momentum and in-force business growth across most markets, higher contributions from joint ventures, and higher investment earnings, partially offset by higher expenses primarily reflecting continued investments in the business, unfavourable credit experience, and lower earnings on surplus primarily reflecting realized losses.

Reported net income of $637 million increased $219 million or 52%, driven by a gain from increased ownership interest in Bowtie, the increase in underlying net income, favourable ACMA impacts, and the prior year impact of a Pillar Two global minimum tax adjustment(2), partially offset by a prior year gain on partial sale of ABSLAMC and unfavourable market-related impacts. The market-related impacts were primarily from unfavourable other market-related and equity market impacts, partially offset by improved interest rate impacts and real estate experience.

Foreign exchange translation led to an increase of $15 million in underlying net income and reported net income, respectively.

(1)Effective Q1'25, Regional office expenses & other was moved to the Individual - Protection business type, reflecting a reporting refinement. Prior period amounts reflect current presentation.

H. Investments

Total general fund invested assets of $197.3 billion as at September 30, 2025, were up $7.5 billion from December 31, 2024. The increase was primarily from general operating activities and net fair value growth from changes in interest rates and credit spreads, partially offset by unfavourable impacts from foreign exchange translation. Our general fund invested assets are well-diversified across investment types, geographies and sectors with the majority of our portfolio invested in high quality fixed income assets.

The following table sets out the composition of our general fund invested assets(1):


	September 30, 2025		December 31, 2024
($ millions)	Carrying value	% of Total carrying value	Carrying value	% of Total carrying value
Cash, cash equivalents and short-term securities	12,911	7%	13,873	7%
Debt securities	85,358	43%	81,955	43%
Equity securities	12,104	6%	9,974	5%
Mortgages and loans	59,859	30%	57,619	31%
Derivative assets	1,588	1%	1,971	1%
Other invested assets	16,268	8%	15,135	8%
Investment properties	9,250	5%	9,290	5%
Total invested assets	197,338	100%	189,817	100%

(1)The values and ratios presented are based on the fair value of the respective asset categories. Generally, the carrying values for invested assets are equal to their fair values. For invested assets supporting insurance contracts, in the event of default, if the amounts recovered are insufficient to satisfy the related insurance contract liability cash flows that the assets are intended to support, credit exposure may be greater than the carrying value of the assets.

1. Debt Securities

The debt securities portfolio is actively managed through a regular program of purchases and sales aimed at optimizing yield, quality, and liquidity, while ensuring that it remains well-diversified and duration-matched to insurance contract liabilities. As at September 30, 2025, with the exception of certain countries where we have business operations, including Canada, the United States, the United Kingdom and the Philippines, our exposure to debt securities from any single country did not exceed 1% of total invested assets.

Debt Securities by Geography

The carrying value of our debt securities by geographic location is presented in the following table.


	September 30, 2025				December 31, 2024
($ millions)	FVTPL debt securities	FVOCI debt securities	Total	% of Total	FVTPL debt securities	FVOCI debt securities	Total	% of Total
Debt securities by geography:
Canada	35,428	3,554	38,982	46%	34,472	3,614	38,086	46%
United States	23,137	6,354	29,491	34%	20,986	6,486	27,472	34%
Europe	4,306	1,434	5,740	7%	4,145	1,664	5,809	7%
Asia	7,110	967	8,077	9%	6,891	950	7,841	10%
Other	1,875	1,193	3,068	4%	1,612	1,135	2,747	3%
Total debt securities	71,856	13,502	85,358	100%	68,106	13,849	81,955	100%

Our gross unrealized losses as at September 30, 2025 for FVTPL and FVOCI debt securities were $5,792 million and $278 million, respectively (December 31, 2024 - $6,775 million and $508 million, respectively). The decrease in gross unrealized losses was largely due to the impact from declining interest rates.

Debt Securities by Credit Rating

Debt securities with a credit rating of "A" or higher represented 76% of the total debt securities as at September 30, 2025 (December 31, 2024 - 75%). Debt securities with a credit rating of "BBB" or higher represented 99% of total debt securities as at September 30, 2025 (December 31, 2024 - 99%).

(1)The geographic location for mortgages is based on the location of the property and for loans it is based on the country of the creditor's parent.

Mortgage Portfolio

As at September 30, 2025, we held $14.1 billion of mortgages (December 31, 2024 - $14.4 billion). Our mortgage portfolio consists entirely of commercial mortgages, as presented in the following table.


	September 30, 2025			December 31, 2024
($ millions)	Insured	Uninsured	Total	Insured	Uninsured	Total
Mortgages:
Retail	—	2,318	2,318	—	2,567	2,567
Office	—	2,454	2,454	—	2,633	2,633

% of Total mortgages	25%	75%	100%	25%	75%	100%

Our mortgage portfolio consists entirely of commercial mortgages, including retail, office, multi-family, and industrial properties. As at September 30, 2025, 31% of our commercial mortgage portfolio consisted of multi-family residential mortgages; there are no single-family residential mortgages. Our uninsured commercial portfolio had a weighted average loan-to-value ratio of approximately 54% as at September 30, 2025 (December 31, 2024 - 54%). While we generally limit the maximum loan-to-value ratio to 75% at issuance, we may invest in mortgages with a higher loan-to-value ratio in Canada if the mortgage is insured by the Canada Mortgage and Housing Corporation ("CMHC"). The estimated weighted average debt service coverage for our uninsured commercial portfolio is 1.76 times. Of the $3.4 billion of multi-family residential mortgages in the Canadian commercial mortgage portfolio, 92% were insured by the CMHC.

As at September 30, 2025, we held $45.7 billion of loans (December 31, 2024 - $43.2 billion). Private placement loans provide diversification by type of loan, industry segment and borrower credit quality. The private placement loan portfolio consists of senior secured and unsecured loans to large- and mid-market corporate borrowers, securitized lease/loan obligations secured by a variety of assets, and project finance loans in sectors such as power and infrastructure.

As at September 30, 2025, our impaired mortgages and loans, net of allowances for losses, were $22 million (December 31, 2024 - $30 million).

3. Derivatives

The values associated with our derivative instruments are presented in the following table. Notional amounts serve as the basis for payments calculated under derivatives contracts and are generally not exchanged.


($ millions)	September 30, 2025	December 31, 2024
Net fair value asset (liability)	(430)	(106)
Total notional amount	83,142	74,954
Credit equivalent amount(1)	1,200	1,347
Risk-weighted credit equivalent amount(1)	26	30

(1)Amounts presented are net of collateral received.

The net fair value of derivatives was a liability of $430 million as at September 30, 2025 (December 31, 2024 - liability of $106 million). The decrease in net fair value was driven by a decrease in interest rate contracts primarily due to upward shift in Canadian yield curves for longer maturing deals and a decrease in foreign exchange contracts due to relative downward shifts in interest rates curves.

28 Sun Life Financial Inc. Third Quarter 2025 MANAGEMENT'S DISCUSSION AND ANALYSIS

The total notional amount of our derivatives increased to $83.1 billion as at September 30, 2025 (December 31, 2024 - $75.0 billion). The change in notional amount is mainly attributable to an increase in interest rate contracts used for duration matching and replication of fixed income exposure.

4. Investment Properties

As at September 30, 2025, we held $9.3 billion of investment properties (December 31, 2024 - $9.3 billion). Declines in market value and unfavourable impacts from foreign exchange translation were offset by net property purchases in Canada.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Third Quarter 2025 29


I. Risk Management

We have established a Risk Management Framework to assist in identifying, measuring, managing, monitoring and reporting risks. The Risk Management Framework covers all risks and these have been grouped into six major categories: market, insurance, credit, business and strategic, operational and liquidity risks. Through our enterprise risk management processes, we oversee the various risk factors identified in the Risk Management Framework and provide reports to senior management and to the Board Committees at least quarterly. Our enterprise risk management processes and risk factors are described in our 2024 Annual MD&A.

This section includes our disclosure on market risks and should be read in conjunction with our unaudited Interim Consolidated Financial Statements for the quarter ended September 30, 2025. When referring to segregated funds in this section, it is inclusive of segregated fund guarantees, variable annuities and investment products.

Equity Risk

Equity risk is the potential for financial loss arising from declines or volatility in public or private equity market prices. We are exposed to equity risk from a number of sources.

We generate revenue in our asset management businesses and from certain protection and wealth contracts where fees are levied on account balances that are affected directly by equity market levels. Accordingly, we have further exposure to equity risk as adverse fluctuations in the market value of such assets will result in corresponding adverse impacts on revenue, income, the contractual service margin, and capital. In addition, declining and volatile equity markets may have a negative impact on sales and redemptions (surrenders) in these businesses, and this may result in further adverse impacts on net income, the contractual service margin, and capital.

A portion of our exposure to equity risk arises in connection with benefit guarantees on segregated fund products, some participating insurance contracts, some adjustable insurance contracts, and some universal life contracts. These benefit guarantees may be triggered upon death, maturity, withdrawal or annuitization. The cost of providing these guarantees is uncertain and depends upon a number of factors, including general capital market conditions, our hedging strategies, policyholder behaviour and mortality experience, each of which may result in negative impacts on net income, the contractual service margin, and capital.

We also have direct exposure to equity markets from the investments supporting other general account liabilities, surplus, and employee benefit plans. These exposures fall within our risk-taking philosophy and appetite, and are therefore generally not hedged.

Interest Rate and Spread Risk

Interest rate and spread risk includes the potential for financial loss arising from changes in the value of insurance and investment contract liabilities and financial assets due to changes or volatility in interest rates or spreads. In practice, when asset cash flows and the policy obligations they support are not matched, this may result in the need to either sell assets to meet policy payments and expenses or reinvest excess asset cash flows in unfavourable interest rate or credit spread environments. This risk is managed in our asset-liability management program. Details of the asset-liability management program are discussed under the heading "Market Risk Management Strategies" in section K - Risk Management in the 2024 Annual MD&A.

Our primary exposure to interest rate and spread risk arises from insurance and investment contracts that contain guarantees in the form of minimum crediting rates, maximum premium rates, settlement options, guaranteed annuitization options and minimum benefits. If investment returns fall below guaranteed levels, we may be required to increase liabilities or capital in respect of these contracts. The guarantees attached to these products may be applicable to both past premiums collected and future premiums not yet received. Segregated fund contracts provide benefit guarantees that are linked to underlying fund performance and may be triggered upon death, maturity, withdrawal or annuitization. Exposure to guarantees is managed within our risk appetite limits through our asset-liability management program, which may include the use of hedging strategies utilizing interest rate derivatives such as interest rate floors, swaps, futures and swaptions. The impact of these guarantees on net income, contractual service margin, and capital are included in the disclosed market risk sensitivities.

Significant changes or volatility in interest rates or spreads could have a negative impact on sales of certain protection and wealth products, and adversely impact the expected pattern of redemptions (surrenders) on existing policies.

•Increases in interest rates or widening credit spreads may increase the risk that policyholders will surrender their contracts, potentially forcing us to liquidate assets at a loss. While we have established hedging programs in place and our protection and wealth products often contain surrender mitigation features, these may not be sufficient to fully offset the adverse impact of changes in interest rates or spreads.

•Declines in interest rates or narrowing spreads can result in compression of the net spread between interest earned on investments and interest credited to policyholders, increased asset calls, mortgage and structured security prepayments, and net reinvestment of positive cash flows at lower yields, and therefore can adversely impact our profitability and financial position.

•Negative interest rates may additionally result in losses on our cash and short-term deposits and low or negative returns on our fixed income assets impacting our profitability.

•A sustained low interest rate environment may additionally adversely impact our net income, CSM, capital, and our ability to implement our business strategy and plans. This may be realized through lower sales, less profitable new business, changes in the pattern of redemptions on existing policies, among other impacts.

We also have direct exposure to interest rates and spreads from investments supporting other general account liabilities, surplus and employee benefit plans. Higher interest rates or wider spreads will reduce the value of our existing assets. Conversely, lower interest rates or a narrowing of spreads will result in reduced investment income on new fixed income asset purchases. These exposures fall within our risk-taking philosophy and appetite and are therefore generally not hedged.

30 Sun Life Financial Inc. Third Quarter 2025 MANAGEMENT'S DISCUSSION AND ANALYSIS

Real Estate Risk

Real estate risk is the potential for financial loss arising from fluctuations in the value of, or future cash flows from, our investments in real estate. We are exposed to real estate risk and may experience financial losses resulting from the direct ownership of real estate investments or indirectly through fixed income investments secured by real estate property, leasehold interests, ground rents, and purchase and leaseback transactions.

Real estate price risk may arise from external market conditions, inadequate property analysis, inadequate insurance coverage, inappropriate real estate appraisals, or from environmental risk exposures.

We hold real estate investments that support general account liabilities and surplus, and fluctuations in value will affect our net income, CSM, and capital. A material and sustained increase in interest rates may lead to deterioration in real estate values.

Foreign Currency Risk

Foreign currency risk is the result of mismatches in the currency of our assets and liabilities (inclusive of capital), and cash flows. This risk may arise from a variety of sources such as foreign currency transactions and services, foreign currency hedging, investments denominated in foreign currencies, investments in foreign subsidiaries and net income from foreign operations. Changes or volatility in foreign exchange rates, including a change to currencies that are fixed in value to another currency, could adversely affect our net income, contractual service margin and capital.

As an international provider of financial services, we operate in a number of countries, with revenues and expenses denominated in several local currencies. In each country in which we operate, we generally maintain the currency profile of assets to match the currency of liabilities and required capital. This approach provides an operational hedge against disruptions in local operations caused by currency fluctuations. Foreign currency derivative contracts such as currency swaps and forwards are used as a risk management tool to manage the currency exposure in accordance with our Asset Liability Management Policy. As at September 30, 2025 and December 31, 2024, the Company did not have a material foreign currency risk exposure.

Changes in exchange rates can affect our net income and surplus when financial results in functional currencies are translated into Canadian dollars. Net income earned outside of Canada is generally not currency hedged and a weakening in the local currency of our foreign operations relative to the Canadian dollar can have a negative impact on our net income reported in Canadian currency. A strengthening in the local currency of our foreign operations relative to the Canadian dollar would have the opposite effect. Regulatory capital ratios could also be impacted by changes in exchange rates.

Inflation Risk

Inflation risk is the potential for financial loss arising from changes in inflation rates. This risk results from insurance contract liabilities that are linked to market measures of inflation such as the Consumer Price Index. The primary sources for this risk exposure are from certain group and retail annuity contracts and group long term disability contracts. In these contracts, the annuity and disability benefit payments may be linked to an indexing formula containing an inflation price index. Benefit payments linked to inflation indices may also include various caps, floors and averaging mechanisms that vary across product designs.

Exposure to inflation risk is managed within our asset-liability management program, primarily by investing in inflation linked assets to match liability exposures.

i. Market Risk Sensitivities

We utilize a variety of methods and measures to quantify our market risk exposures. These include duration management, key rate duration techniques, convexity measures, cash flow gap analysis, scenario testing, and sensitivity testing of earnings and regulatory capital ratios versus risk appetite limits.

The measurement of liabilities and assets are affected by the level of equity market performance, interest rates, credit and swap spreads and other market risk variables. The following sections set out the estimated immediate impact on, or sensitivity of, our net income(1), contractual service margin, OCI and SLF Inc.'s LICAT ratio to certain instantaneous changes in market variables as at September 30, 2025 and December 31, 2024.

The estimated sensitivities in the tables below reflect the impact of market movements on insurance contracts and investment contracts, assets backing insurance contracts, assets backing investment contracts, assets backing the surplus segment, and seed investments in our asset management subsidiaries.

Net income sensitivities to equity and real estate market movements are driven primarily by changes in the value of investments backing general account liabilities and surplus. Net income sensitivities to interest rates and spreads are driven by the net impact on liabilities and the assets backing them. Lower interest rates or a narrowing of spreads will result in increased liabilities for insurance contracts, offset by increased values of the assets backing general account liabilities. Higher interest rates or a widening of spreads will result in decreased liabilities for insurance contracts, offset by decreased values of the assets backing general account liabilities. Further detail on the impact of changes or volatility in market prices on assets and liabilities is provided under the headings "Equity Risk", "Interest Rate and Spread Risk", and "Real Estate Risk" above.

OCI sensitivities are impacted by changes in the market value of assets classified as FVOCI. The market value of FVOCI fixed income assets, which are held primarily backing surplus, investment contracts and CSM liabilities, increases with lower interest rates or a narrowing of spreads, and decreases with higher interest rates or widening of spreads.

(1)Net income in section I - Risk Management in this document refers to common shareholders' net income.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Third Quarter 2025 31

As these market risk sensitivities reflect an instantaneous impact on net income, CSM, OCI and SLF Inc.'s LICAT ratio, they do not include impacts over time such as the effect on fee income in our asset management businesses.

Refer to Additional Cautionary Language and Key Assumptions Related to Sensitivities in this section for important additional information regarding these estimates.

1. Private and Public Equity Market Sensitivities

The following table sets out the estimated immediate impact on, or sensitivity of, our net income, CSM, OCI and SLF Inc.'s LICAT ratio to certain instantaneous changes in public or private equity market prices as at September 30, 2025 and December 31, 2024. The sensitivities shown outline the impact of the same percentage increase or decrease applied to each of private equity and public equity. About 60% of our expected net income sensitivity to changes in equity markets is driven by investments in private equity.

(1)Interest rate sensitivities assume a parallel shift in assumed interest rates across the entire yield curve as at September 30, 2025 and December 31, 2024 with no change to the ultimate risk-free rate. Variations in realized yields based on factors such as different terms to maturity and geographies may result in realized sensitivities being significantly different from those illustrated above. Sensitivities include the impact of re-balancing interest rate hedges for hedging programs at 10 basis point intervals (for 50 basis point changes in interest rates).

(2)The market risk sensitivities include the estimated impact of our hedging programs in effect as at September 30, 2025 and December 31, 2024, and include new business added and product changes implemented prior to such dates.

(4)The market risk OCI sensitivities exclude the impact of changes in the defined benefit obligations and plan assets.

(5)The LICAT sensitivities illustrate the impact on SLF Inc. as at September 30, 2025 and December 31, 2024. The sensitivities reflect the worst scenario as at September 30, 2025 and assume that a scenario switch does not occur in the quarter. LICAT ratios are rounded in increments of 0.5%.

The above sensitivities were determined using a 50 basis point change in interest rates and 10% and 25% changes in our equity markets because we believe that these market shocks were reasonably possible as at September 30, 2025. Significant changes in market variables may result in other than proportionate impacts on our sensitivities.

3. Credit Spread and Swap Sensitivities

The following tables set out the estimated immediate impact on, or sensitivity of, our net income, CSM, OCI and SLF Inc.'s LICAT ratio to certain instantaneous changes in credit spreads and our net income, CSM, and OCI to certain changes in swap spreads as at September 30, 2025 and December 31, 2024.

LICAT Interest Rate Scenario Switch

The LICAT interest rate risk is assessed under four different interest rate scenarios, and the scenario leading to the highest capital requirement is chosen as the worst scenario for each geographic region as defined by the LICAT guideline. Changes and interaction between the level and term movements in interest rates and credit spreads can shift the interest rate scenario applied in the LICAT calculation causing a discontinuity where capital requirements change materially. In 2020, OSFI updated the LICAT guideline for interest rate risk requirements for participating businesses to be smoothed over six quarters. As a result, the actual impact to the LICAT ratio from participating businesses in any quarter will reflect the scenarios from current quarter as well as the prior five quarters and switching between the scenarios would have the effect of offsetting the previous impacts over time. It should be noted that switching of the scenario can also change the direction of our sensitivities.

For SLF Inc., assuming no further scenario switches, no additional LICAT ratio impact is expected over the next five quarters.

For Sun Life Assurance, assuming no further scenario switches, there is an additional four percentage point decrease to the LICAT ratio impact expected over the next five quarters.

5. Additional Cautionary Language and Key Assumptions Related to Sensitivities

Our market risk sensitivities are measures of our estimated change in net income, OCI, CSM and LICAT ratio for changes in market risk variables described above, based on market risk variables and business in force as at the reporting date. These sensitivities are calculated independently for each risk factor, generally assuming that all other risk variables stay constant. The sensitivities do not take into account indirect effects such as potential impacts on goodwill impairment or valuation allowances on deferred tax assets.

We have provided measures of our net income sensitivity to instantaneous changes in equity markets, interest rates, credit spreads, swap spreads, real estate price levels, and capital sensitivities to changes in equity price levels, interest rates and credit spreads. The LICAT ratio and CSM sensitivities are non-IFRS financial measures, and for additional information, see section N - Non-IFRS Financial Measures in this document. The cautionary language which appears in this section is applicable to all net income, CSM, OCI and LICAT ratio sensitivities.

Actual results can differ materially from these estimates for a variety of reasons, including differences in the pattern or distribution of the market shocks, the interaction between these risk factors, model error, or changes in other assumptions such as business mix, effective tax rates, policyholder behaviour, currency exchange rates and other market variables relative to those underlying the calculation of these sensitivities. The extent to which actual results may differ from the indicative ranges will generally increase with larger movements in risk variables. Our sensitivities as at December 31, 2024 have been included for comparative purposes only.

Sensitivities to interest rates and credit spreads assume a parallel shift in assumed interest rates across the entire yield curve or a parallel shift in the indicated spreads across the entire term structure, with no change to the ultimate risk-free rate or ultimate liquidity premium. Realized sensitivities may be significantly different from those illustrated based on factors such as different terms to maturity, geographies, asset classes and derivative types, and ratings.

The sensitivities reflect the composition of our assets and liabilities as at September 30, 2025 and December 31, 2024, respectively. Changes in these positions due to new sales or maturities, asset purchases/sales, or other management actions could result in material changes to these reported sensitivities. In particular, these sensitivities reflect the expected impact of hedging activities based on the hedging programs in place as at the respective calculation dates. The actual impact of hedging activity can differ materially from that assumed in the estimated sensitivities due to ongoing hedge re-balancing activities, changes in the scale or scope of hedging activities, changes in the cost or general availability of hedging instruments, basis risk (i.e., the risk that hedges do not exactly replicate the underlying portfolio experience), model risk, and other operational risks in the ongoing management of the hedge programs or the potential failure of hedge counterparties to perform in accordance with expectations.

The sensitivities are based on methods and assumptions in effect as at September 30, 2025 and December 31, 2024, as applicable. Changes in the regulatory environment, assumptions or methods used to measure assets and liabilities after those dates could result in material changes to the estimated sensitivities. Changes in market risk variables in excess of the changes illustrated may result in other than proportionate impacts.

The sensitivities reflect the CSM as at September 30, 2025 and December 31, 2024. For insurance contracts measured using the VFA, where the change in the effect of the time value of money and financial risk not arising from the underlying items adjusts the CSM, changes in the CSM balance will affect the sensitivity of income to changes in market risk variables.

Our LICAT sensitivities may be non-linear and can change due to the interrelationship between market rates and spreads, actuarial

assumptions and our LICAT calculations.

34 Sun Life Financial Inc. Third Quarter 2025 MANAGEMENT'S DISCUSSION AND ANALYSIS

For the reasons outlined above, our sensitivities should only be viewed as indicative estimates of the underlying sensitivities of each factor under these specialized assumptions, and should not be viewed as predictors of our future income, OCI, CSM or capital. Given the nature of these calculations, we cannot provide assurance that actual impacts will be consistent with the estimates provided.

Information related to market risk sensitivities should be read in conjunction with the information contained in section N - Accounting and Control Matters - 1 - Critical Accounting Policies and Estimates in the 2024 Annual MD&A. Additional information on market risk can be found in Note 6 of the 2024 Annual Consolidated Financial Statements and the Risk Factors section in the 2024 AIF.

Total revenue	12,421	9,199	15,333	32,971	31,124

Total revenue decreased $2.9 billion compared to the prior year, primarily driven by lower net investment income from fair value changes of invested assets, partially offset by higher insurance revenue. Foreign exchange translation led to a $63 million increase in revenue. By business group, total revenue reflected lower net investment income from fair value changes of invested assets in Canada, the U.S., and Asia, partially offset by higher insurance revenue primarily in Asia, Canada and the U.S.

Total revenue increased $1.8 billion in the first nine months of 2025 compared to the same period in 2024, primarily driven by higher insurance revenue. Foreign exchange translation led to a $562 million increase in revenue. By business group, revenue reflected higher insurance revenue primarily in the U.S., Canada and Asia. Higher net investment income in Asia and the U.S. was offset by lower net investment income from fair value changes of invested assets, in Canada.

2. Changes in the Statements of Financial Position and in Shareholders' Equity

Total general fund assets were $230.0 billion as at September 30, 2025 (December 31, 2024 - $221.9 billion), primarily driven by general operating activities and net fair value growth from changes in interest rates and credit spreads, partially offset by unfavourable impacts from foreign exchange translation.

The net liabilities balance for insurance contracts issued(1) was $153.8 billion as at September 30, 2025 (December 31, 2024 - $146.9 billion), primarily driven by insurance finance income and expenses, and cash flows, partially offset by foreign currency translation.

Total shareholders' equity, including preferred shares and other equity instruments, is $25.1 billion as at September 30, 2025
(December 31, 2024 - $25.6 billion). The change in total shareholders' equity included:

(i)common share dividend payments of $1,465 million;

(ii)a decrease of $1,315 million from the repurchase and cancellation of common shares; and

(iii)unfavourable impacts from foreign exchange translation of $590 million included in OCI; partially offset by

(iv)total shareholders' net income of $2,809 million, before preferred share dividends of $59 million; and

(v)net unrealized gains on FVOCI assets of $241 million.

As at October 24, 2025, SLF Inc. had 557,419,086 common shares, 2,959,752 options to acquire SLF Inc. common shares, and 52,200,000 Class A Shares outstanding.

Our operating activities generate cash flows which include net premiums, net investment income, fee income, and the sale and maturity of investments. They are the principal source of funds to pay for policyholder claims and benefits, commissions, operating expenses, and the purchase of investments. Cash flows used in investing activities primarily include transactions related to associates, joint ventures and acquisitions. Cash flows provided by and used in financing activities largely reflect capital transactions including payments of dividends, the issuance and repurchase of shares, as well as the issuance and retirement of debt instruments and preferred shares.

Q3'25 cash flows used in financing activities were lower year-over-year driven by the issuance of $1 billion principal amount of Series 2025-1 Subordinated Unsecured 4.14% Fixed/Floating Debentures, and the prior year included the redemption of $750 million principal amount of Series 2019-1 Subordinated Unsecured 2.38% Fixed/Floating Debentures.

Second Quarter 2025

Underlying net income of $1,015 million increased $15 million or 2%, driven by:

•Asset management & wealth was in line with the prior year as higher fee-related earnings in SLC Management reflecting strong capital raising, and higher fee income in Asia from higher AUM, was offset by lower fee income in MFS from lower ANA, and lower investment contributions from lower yields.

•Group - Health & Protection up $21 million: Improved U.S. Dental results primarily reflecting Medicaid repricing, higher fee income and management actions, and favourable mortality experience in Canada.

•Individual - Protection down $33 million: Higher expenses in Asia primarily reflecting continued investments in the business, and unfavourable mortality experience in Canada and the U.S., partially offset by business growth in Asia.

•Corporate expenses & other $27 million decrease in net loss primarily driven by timing of strategic investment spend, and lower incentive compensation.

Reported net income of $716 million increased $70 million or 11% from prior year, driven by a prior year restructuring charge of $108 million in Corporate and the increase in underlying net income partially offset by an impairment charge of $61 million on a customer relationship intangible asset from the early termination of a U.S. group dental contract and unfavourable other market-related impacts driven across Asia and Canada, partially offset by favourable interest rate impacts primarily from non-parallel curve changes in Canada, and improved real estate experience.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Third Quarter 2025 37

First Quarter 2025

Underlying net income of $1,045 million increased $170 million or 19% from prior year, driven by:

•Asset management & wealth up $79 million: Higher fee-related earnings from catch-up fees and strong performance of net seed investment income in SLC Management, and higher fee income in Canada and Asia.

•Group - Health & Protection up $50 million: Business growth and favourable protection experience in Canada primarily from morbidity and mortality experience, and higher U.S. Dental results, partially offset by moderately unfavourable morbidity experience in U.S. medical stop-loss.

•Individual - Protection up $55 million: Business growth and higher contributions from joint ventures in Asia, and improved protection experience in Canada largely from mortality experience.

•Corporate expenses & other $(14) million increase in net loss primarily reflecting lower investment income from surplus assets.

Reported net income of $928 million increased $110 million or 13% from prior year, driven by the increase in underlying net income, market-related impacts primarily reflecting improved real estate experience and favourable interest rate impacts partially offset by unfavourable equity market impacts, and fair value changes in MFS shares owned by management, partially offset by prior year gains on partial sale of ABSLAMC and the early termination of a distribution agreement in Asset Management.

Fourth Quarter 2024

Underlying net income of $965 million decreased $18 million or 2%, driven by:

•Asset management & wealth up $47 million: Higher fee income in Asset Management, Canada, and Asia, partially offset by lower net investment results in Canada.

•Group - Health & Protection down $99 million: Unfavourable morbidity experience in U.S. medical stop-loss and less favourable morbidity experience in Canada, partially offset by business growth in Canada.

•Individual - Protection up $55 million: Improved protection experience in Asia and Canada and higher contributions from joint ventures in Asia.

•Corporate expenses & other $(21) million increase in net loss primarily reflecting higher expenses largely from continued investments in our Asia businesses and incentive compensation in Asia.

Reported net income of $237 million decreased $512 million or 68%, driven by lower tax-exempt investment income of $234 million in Corporate, an impairment charge of $186 million on an intangible asset related to bancassurance in Vietnam reflecting updates resulting from changes in regulatory and macro-economic factors, and a non-recurring provision in U.S. Dental, partially offset by market-related impacts primarily reflecting improved real estate experience.

Third Quarter 2024

Underlying net income of $1,016 million increased $86 million or 9%, driven by:

•Asset management & wealth up $17 million: Higher fee income in Asset Management, Asia, and Canada, partially offset by unfavourable credit experience in Canada.

•Group - Health & Protection up $60 million: Strong business growth in U.S. Group Benefits and Canada, higher fee-based income in Canada, and improved group life mortality experience in the U.S., partially offset by lower U.S. Dental results.

•Individual - Protection up $9 million: Business growth in Asia and Canada partially offset by unfavourable mortality experience in Asia.

•Corporate expenses & other were in line with prior year.

Reported net income of $1,348 million increased $477 million or 55%, driven by a decrease in SLC Management's estimated acquisition-related liabilities and the increase in underlying net income. Favourable equity market impacts and improved real estate experience were offset by interest rate impacts.

Second Quarter 2024

Underlying net income of $1,000 million increased $80 million or 9%, driven by:

•Asset management & wealth up $36 million: Higher fee income in Asset Management, Canada, and Asia, partially offset by higher expenses in Asset Management.

•Group - Health & Protection down $55 million: Lower results in U.S. Dental primarily reflecting the impact of Medicaid redeterminations and related claims following the end of the Public Health Emergency, less favourable morbidity experience in Canada, and unfavourable morbidity experience in U.S. medical stop-loss, partially offset by strong business growth in U.S. Group Benefits and Canada.

•Individual - Protection up $82 million: Business growth in Asia and Canada, and favourable mortality experience in Canada and the U.S.

•Corporate expenses & other $17 million decrease in net loss driven by lower operating expenses and financing costs.

Reported net income of $646 million decreased $14 million or 2%. Financial discipline remains core to our Client Impact Strategy and business. In Q2'24, we recorded a restructuring charge of $138 million (post-tax $108 million) reflecting actions taken to improve productivity and drive earnings growth at the higher-end of our Medium-Term Financial Objectives. We expect these actions to result in annual savings of approximately $200 million (pre-tax) by 2026. The restructuring charge is offset by the increase in underlying net income; and market-related impacts primarily reflecting interest rates and real estate investments.

38 Sun Life Financial Inc. Third Quarter 2025 MANAGEMENT'S DISCUSSION AND ANALYSIS

First Quarter 2024

Underlying net income of $875 million decreased $20 million from prior year, driven by:

•Asset management & wealth down $3 million: Higher fee income offset by higher expenses in Asset Management, as well as lower net seed investment income in SLC Management.

•Group - Health & Protection down $23 million: Less favourable morbidity experience in U.S. medical stop-loss and lower results in U.S. Dental primarily reflecting the impact of Medicaid redeterminations following the end of the Public Health Emergency, partially offset by strong revenue growth in U.S. Group Benefits, and business growth and improved disability experience in Canada.

•Individual - Protection down $13 million: Lower earnings due to the sale of Sun Life UK partially offset by business growth in Asia.

•Corporate expenses & other $19 million decrease in net loss driven by lower financing costs.

Reported net income of $818 million increased $12 million from prior year, driven by the gains on partial sale of ABSLAMC and the early termination of a distribution agreement in Asset Management, largely offset by the prior year gain on sale of the sponsored markets business in Canada, fair value changes in MFS shares owned by management, and the decrease in underlying net income. Unfavourable real estate experience was mostly offset by favourable interest rate impacts.

Fourth Quarter 2023

Underlying net income of $983 million increased $91 million or 10% from prior year, driven by:

•Asset management & wealth up $27 million: Higher Asset Management fee-related earnings and higher investment income driven by volume growth and an increase in yields.

•Group - Health & Protection up $44 million: Business premium growth in the U.S. and Canada, improved disability experience in Canada, and higher investment contributions in the U.S., partially offset by lower results in U.S. Dental.

•Individual - Protection up $53 million: Business growth reflecting good sales momentum in Asia, and higher investment contributions in Canada, partially offset by lower earnings due to the sale of Sun Life UK.

•Corporate expenses & other $(33) million increase in net loss driven by higher operating expenses reflecting business growth and continued investments in the business, partially offset by a lower effective tax rate.

•Higher earnings on surplus primarily driven by higher net interest income and lower realized losses.

Reported net income of $749 million decreased $416 million or 36%, driven by unfavourable market-related impacts primarily reflecting interest rates and real estate experience, the prior year impact of the Canada Tax Rate Change, and fair value changes in MFS shares owned by management; partially offset by the increase in underlying net income, the impact of the Bermuda Corporate Income Tax Change; and lower DentaQuest integration costs.

2. Underlying Net Income and Underlying EPS

Underlying net income is a non-IFRS financial measure that assists in understanding Sun Life's business performance by making certain adjustments to IFRS income. Underlying net income, along with common shareholders’ net income (Reported net income), is used as a basis for management planning, and is also a key measure in our employee incentive compensation programs. This measure reflects management's view of the underlying business performance of the company and long-term earnings potential. For example, due to the longer term nature of our individual protection businesses, market movements related to interest rates, equity markets and investment properties can have a significant impact on reported net income in the reporting period. However, these impacts are not necessarily realized, and may never be realized, if markets move in the opposite direction in subsequent periods or in the case of interest rates, the fixed income investment is held to maturity.

Underlying net income removes the impact of the following items from reported net income:

•Market-related impacts reflecting the after-tax difference in actual versus expected market movements, including:

i)Net interest impact from risk-free rate, credit spread, swap spread movements, and other impacts, reflecting accounting mismatches between assets and liabilities:

a.Differences arising from fair value changes(1) of fixed income assets (including derivatives) measured at FVTPL supporting insurance contracts, compared to fair value changes of the liabilities(2);

b.Fair value changes of fixed income assets (including derivatives) measured at FVTPL supporting our investment contract liability and surplus portfolios(3); and

c.Tax-exempt investment(4) income above or below expected long-term tax savings relating to our Canadian multi-national insurance operations.

ii)Non-fixed income investments where the weighted average expected return is approximately 2% per quarter, including:

a.Equity investments (including derivatives) supporting insurance contracts and surplus portfolios; and

b.Investment properties supporting insurance contracts and surplus portfolios.

•ACMA – captures the impact of method and assumption changes, and management actions on insurance and reinsurance contracts.

•Other adjustments:

i)MFS shares owned by management – this adjustment removes the change in fair value and other activity related to MFS common shares owned by management.

ii)Acquisition, integration, and restructuring – expense and income related to acquisition or disposal of a business. Also includes expenses related to restructuring activities.

iii)Intangible asset amortization – removes the amortization expense associated with finite life intangible assets arising from acquisitions or business combinations excluding amortization of software and distribution agreements.

iv)Other – represents items that are unusual or exceptional in nature which management believes are not representative of the long-term performance of the Company.

Underlying EPS (diluted). This measure is used in comparing the profitability across multiple periods and is calculated by dividing underlying net income by weighted average common shares outstanding for diluted EPS, excluding the dilutive impact of convertible instruments. For additional information about the underlying net income, see above. For additional information about the composition of the EPS, please refer to Note 13 of our Interim Consolidated Financial Statements for the period ended September 30, 2025. For additional information about the SLEECS, please refer to Note 12 of our 2024 Annual Consolidated Financial Statements.

(1)For fixed income assets, Underlying Net Income includes credit experience from rating changes on assets measured at FVTPL, and the ECL impact for assets measured at FVOCI.

(2)Underlying net income is based on observable discount curves and exchange rates at the beginning of the period.

(3)Underlying net income for earnings on surplus includes realized gains (losses) on fixed income assets classified as FVOCI.

(4)Q4'24 balances are isolated in Other within Other adjustments.

(5)Q2'24 includes a restructuring charge of $108 million in the Corporate business group.

(6)To meet regulatory obligations, in Q1'24, we sold 6.3% of our ownership interest in ABSLAMC, generating a gain of $84 million. As a result of the transaction, our ownership interest in ABSLAMC was reduced from 36.5% to 30.2% for gross proceeds of $136 million. Subsequently in Q2'24, we sold an additional 0.2% of our ownership interest.

(7)On July 15, 2025, we acquired an additional interest in Bowtie Life Insurance Company Limited ("Bowtie"), which increased our ownership interest, excluding dilution, by approximately 11% and resulted in a total ownership interest of 55.8%. Total consideration was cash of $55 million. Our previously held interest in Bowtie was remeasured to its fair value, which resulted in a gain of $176 million recognized in reported net income in Q3'25 ("gain from increased ownership interest in Bowtie"). For additional information, refer to Note 3 of our Interim Consolidated Financial Statements for the period ended September 30, 2025.

(8)Includes an impairment charge of $61 million on a customer relationship intangible asset from the early termination of a U.S. group dental contract.

(1)In this document, the reported net income impact of ACMA excludes amounts attributable to participating policyholders and includes non-liability impacts. In contrast, the Interim Consolidated Financial Statements for the period ended September 30, 2025 (Note 10.B.v of the 2024 Annual Consolidated Financial Statements) shows the pre-tax net income impacts of method and assumption changes, and CSM Impacts include amounts attributable to participating policyholders.

Taxes related to underlying net income adjustments may vary from the expected effective tax rate range reflecting the mix of business based on the Company's international operations and other tax-related adjustments.

3. Additional Non-IFRS Financial Measures

Management also uses the following non-IFRS financial measures:

After-tax profit margin for U.S. Group Benefits. This ratio expresses U.S. Group Benefits underlying net income as a percentage of net premiums. It assists in explaining our results from period to period and measures profitability. This ratio is calculated by dividing underlying net income (loss) by net premiums for the trailing four quarters. There is no directly comparable IFRS measure.

Assets under administration (in SLC Management). AUA represents Client assets for which Sun Life provides administrative services. In Asset Management, AUA includes assets distributed mostly by SLC Management's affiliate, Advisors Asset Management, Inc. There is no directly comparable IFRS measure.

Assets under management. AUM is a non-IFRS financial measure that indicates the size of our Company's assets across asset management, wealth, and insurance. There is no standardized financial measure under IFRS. In addition to the most directly comparable IFRS measures, which are the balance of General funds and Segregated funds on our Statements of Financial Position, AUM also includes Third-party AUM and Consolidation adjustments. "Consolidation adjustments" is presented separately as consolidation adjustments apply to all components of total AUM.

AUM not yet earning fees. This measure represents the committed uninvested capital portion of total AUM not currently earning management fees. The amount depends on the specific terms and conditions of each fund. There is no directly comparable IFRS measure.

Capital raising. This measure consists of increases in SLC Management's commitments from fund raising activities for all real estate, infrastructure and alternative credit Clients excluding leverage. Investment-grade fixed income capital raising consists of sales made to new Clients. There is no directly comparable IFRS measure.

Cash and other liquid assets. This measure is comprised of cash, cash equivalents, short-term investments, and publicly traded securities, net of loans related to acquisitions and short-term loans that are held at SLF Inc. (the ultimate parent company), and its wholly owned holding companies. This measure is a key consideration of available funds for capital re-deployment to support business growth.


($ millions)	As at September 30, 2025	As at December 31, 2024
Cash and other liquid assets (held at SLF Inc. and its wholly owned holding companies):

(1)Includes publicly traded bonds.

(2)Includes exchange traded fund ("ETF") Investments.

(3)Includes drawdowns from credit facilities to manage timing of cash flows.

Constant currency. We remove the impacts of foreign exchange translation from certain IFRS and non-IFRS measures to assist in comparing our results from period to period. The impacts of foreign exchange translation is approximated by using the foreign exchange rates in effect during the comparative period, using the average or period end foreign exchange rates, as appropriate.

MANAGEMENT'S DISCUSSION AND ANALYSIS Sun Life Financial Inc. Third Quarter 2025 45

CSM Movement Analysis includes certain non-IFRS financial measures, detailed below, and also presents certain measures on a net basis to reflect how the business is managed, compared to a gross basis in the Consolidated Financial Statements. Examples include i) The impacts of insurance contracts issued is presented net of reinsurance; ii) Impact of new business is presented net of acquisition expense gain/loss; and iii) Certain methodology changes are presented as an impact of change in assumptions, whereas the Consolidated Financial Statement presentation is a contract modification.

•Organic CSM Movement is comprised of the Impact of new insurance business, Expected movements from asset returns & locked-in rates, Insurance experience gains/losses, and CSM recognized for services provided.

•Impact of new insurance business on CSM, also referred to as "new business CSM", represents growth from sales activity in the period, including individual protection sales (excluding joint ventures), and defined benefit solutions and segregated fund wealth sales in Canada. New business CSM is presented net of acquisition expense gain/loss.

•Expected movements from asset returns & locked-in rates applies to variable fee approach ("VFA") and general measurement approach ("GMA") contracts. For VFA contracts, this component of the CSM movement analysis is comprised of two factors: (i) the expected return on underlying assets and (ii) the measurement of financial guarantees. The difference between actual and expected results are reported as the impact of markets. For GMA contracts, this component of the CSM includes the accretion of the CSM balance at locked-in rates, which refer to the term structure associated with locked-in discount rates, set when the insurance contract was sold or on transition to IFRS 17. Average locked-in rates increase with the passage of time on in-force business and new business added at current rates.

•Impact of markets & other includes the difference between actual and expected movement for VFA contracts for: (i) the return on underlying assets and (ii) the measurement of financial guarantees. Also includes other amounts excluded from Organic CSM Movement.

•Insurance experience gains/losses represents the current period impacts of insurance experience, resulting in a change in future cash flows that adjust CSM.

•Impact of change in assumptions represents the future period impacts of changes in fulfilment cash flows that adjust CSM.

•CSM market sensitivities. CSM market sensitivities are non-IFRS financial measures for which there are no directly comparable measures under IFRS so it is not possible to provide a reconciliation of these amounts to the most directly comparable IFRS measures.

Deployment. This measure represents the amount of capital that has been invested in the period, including leverage where applicable. Deployment also includes capital committed in infrastructure deals to be invested in specific assets. There is no directly comparable IFRS measure.

Drivers of Earnings. The Drivers of Earnings ("DOE") analysis provides additional detail on the sources of earnings, primarily for protection and health businesses, and explains the actual results compared to the longer term expectations. The DOE is presented on a reported and underlying common shareholders' basis. Within the net insurance service result, the underlying DOE provides detail on expected insurance earnings, impact of new insurance business and experience gains (losses). Within the net investment result, the underlying DOE provides detail on expected investment earnings, credit experience, earnings on surplus, and joint ventures & other. For more information, refer to the headings "Underlying net income and Underlying EPS", "Earnings on surplus", "Notable items attributable to reported and underlying net income", in this document.

Certain amounts in the DOE are presented on a net basis to reflect how the business is managed, compared to a gross basis in the Consolidated Financial Statements. Examples include: i) Net investment result and Other expenses of the Asset Management operating segment are combined with Fee Income to report the net contribution to earnings; ii) Income for fee-based businesses is reported net of the associated expenses; iii) Carried interest in SLC Management within Fee Income excludes the carried interest that Sun Life does not participate in economically, and nets the non-controlling interest portion of the carried interest against fee income and expenses of consolidated funds; iv) Net investment results include assets returns net of the crediting rate for investment contract liabilities and the unwinding of and changes in the discount rate for insurance contract liabilities; v) Earnings on surplus reflects net spread earned from investment strategies; and vi) Earnings attributable to the participating account are excluded.

Earnings on Surplus. This component of the Drivers of Earnings represents the net income earned on a company’s surplus funds. Earnings on Surplus is comprised of realized gains on fair value through other comprehensive income assets, as well as net investment returns on surplus, such as investment income, gains (losses) on seed investments and investment properties mark-to-market, and also includes impacts from derivatives, currency and other items.

Experience-related items attributable to reported net income and underlying net income. These notable items attributable to reported net income and underlying net income are components of the Drivers of Earnings represents gains and losses that are due to differences between the actual results during the reporting period and management’s estimate of the expected longer-term returns on assets and liabilities (i.e. expected insurance earnings and expected investment earnings) at the start of the reporting period.

Fee earning AUM. FE AUM consists of assets managed by SLC Management, which are beneficially owned by Clients, on which we earn management fees for providing investment management, property management or advisory-related services. There is no directly comparable IFRS measure.

Fee-related earnings and Operating income. Fee-related earnings represent profitability of SLC Management's fee-related portfolios, and is calculated as Fee-related revenue less Fee-related expenses. Operating income represents profit realized from our business operations, and is calculated as the sum of Fee-related earnings, Investment income (loss) and performance fees, and Interest and other. Fee-related revenue represents all fee income, with the exception of performance fees, generated from third-party investors. Fee-related expenses represent all expenses directly related to generating fee revenue from third-party investors. Investment income (loss) and performance fees represent total income or loss from our seed investments, net of the related expenses. Interest and other represents performance fee compensation, our net interest income or expense and income from managing the General Account assets.

46 Sun Life Financial Inc. Third Quarter 2025 MANAGEMENT'S DISCUSSION AND ANALYSIS

Fee-related earnings and Operating income are non-IFRS financial measures within SLC Management's Supplemental Income Statement, which enhances the comparability of SLC Management's results with publicly traded alternative asset managers. For more details, see our Supplementary Financial Information package for the quarter.

The following table provides a reconciliation from Fee-related earnings and Operating income to SLC Management's Fee income and Total expenses based on IFRS.

(1)Includes Interest and other - fee income, Investment income (loss) and performance fees - fee income, and Other - fee income.

(2)Excludes the income and related expenses for certain property management agreements to provide more accurate metrics on our fee-related business.

(3)Includes Interest and other, Placement fees - other, Amortization of intangibles, Acquisition, integration and restructuring, and Other - expenses.

(4)Investment income (loss) and performance fee in SLC Management's Supplemental Income Statement relates to the underlying results of our seed investments. As such, we have excluded non-underlying market-related impacts as well as the gains or losses of certain non-seed hedges that are reported under Net investment income (loss) under IFRS. The reconciliation is as follows (amounts have been adjusted for rounding):

Financial leverage ratio. This ratio is an indicator of the Company's balance sheet strength measured by its proportion of capital qualifying debt in accordance with OSFI guidelines. This is calculated as the ratio of total debt plus preferred shares to total capital including the contractual service margin net of taxes, where debt consists of all capital-qualifying debt securities. Capital-qualifying debt securities consist of subordinated debt and innovative capital instruments. The CSM is included net of taxes because debts are repaid and serviced from available after-tax funds.

Impacts of foreign exchange translation. To assist in comparing our results from period-to-period, the favourable or unfavourable impacts of foreign exchange translation are approximated using the foreign exchange rates, in effect during the comparative period, for several IFRS and Non-IFRS financial measures using the average or period end foreign exchange rates, as appropriate. Items impacting a reporting period, such as Revenue, Expenses, and Reported net income (loss) in our Consolidated Statements of Operations, as well as underlying net income (loss), and sales, are translated into Canadian dollars using average exchange rates for the appropriate daily, monthly, or quarterly period. For Assets and Liabilities in our Consolidated Statements of Financial Position, as well as the AUM and certain components of the Drivers of Earnings disclosure, period-end rates are used for currency translation purposes.

LICAT market sensitivities. LICAT market sensitivities are non-IFRS financial measures for which there are no directly comparable measures under IFRS so it is not possible to provide a reconciliation of these amounts to the most directly comparable IFRS measures.

Organic capital generation. This supplementary financial measure provides a view of the Company’s ability to generate excess capital under the normal course of business, excluding non-recurring items; where excess capital is defined as LICAT Available Capital and Surplus Allowance above LICAT Base Solvency Buffer at target ratio, as defined and calculated under OSFI-mandated guideline. This amount is determined as follows: underlying net income and organic CSM movement net of shareholder dividends and change in base solvency buffer for new business and aging of in-force. This amount excludes non-recurring impacts to available capital or base solvency buffer from markets, assumption changes, management actions, and other non-underlying items.

Pre-tax fee related earnings margin. This ratio is a measure of SLC Management's profitability in relation to funds that earn recurring fee revenues, while excluding investment income and performance fees. The ratio is calculated by dividing fee-related earnings by fee-related revenues and is based on the last twelve months. There is no directly comparable IFRS measure.

Pre-tax net operating margin. This ratio is a measure of the profitability and there is no directly comparable IFRS measure. For MFS, this ratio is calculated by excluding MFS shares owned by management and certain commission expenses that are offsetting. These commission expenses are excluded in order to neutralize the impact these items have on the pre-tax net operating margin and have no impact on the profitability of MFS. For SLC Management, the ratio is calculated by dividing the total operating income by fee-related revenue plus investment Income (loss) and performance fees, and is based on the last twelve months.

(1)Other includes accounting basis differences, such as sub-advisory expenses and product allowances.

(2)Excluding non-controlling interest. For more information on MFS shares owned by management, see the heading Underlying Net Income and Underlying EPS.

Return on equity. IFRS does not prescribe the calculation of ROE and therefore a comparable measure under IFRS is not available. To determine reported ROE and underlying ROE, respectively, reported net income (loss) and underlying net income (loss) is divided by the total weighted average common shareholders’ equity for the period. The ROE provides an indication of the overall profitability of the Company. The quarterly ROE is annualized.

Sales and flows. Asset Management gross flows includes funds from retail and institutional Clients; SLC Management gross flows include capital raising, such as uncalled capital commitments and fund leverage. Asset Management net flows consist of gross flows less gross outflows; SLC Management's net flows do not include Client distributions from the sale of underlying assets in closed-end funds. In Canada and in Asia, net sales consist of asset management gross flows & wealth sales less redemptions. In Canada, asset management gross flows & wealth sales consist of sales in Group Retirement Services (excluding retained sales) and Individual Wealth; group - health & protection sales consist of workplace benefits sold by Sun Life Health; and individual - protection sales refer to individual insurance sales. In the U.S., group - health & protection sales consist of sales by Group Benefits and Dental. In Asia, asset management gross flows & wealth sales consist of Hong Kong asset management gross flows & wealth sales, Philippines mutual fund sales, asset management gross flows & wealth sales by our India and China joint ventures and associates, and Aditya Birla Sun Life AMC Limited's equity and fixed income mutual fund sales based on our proportionate equity interest, including sales as reported by our bank distribution partners; individual - protection sales consist of the individual insurance sales, by our subsidiaries and joint ventures and associates, based on our proportionate equity interest, in the Philippines, Indonesia, India, China, Malaysia, Vietnam, International, Hong Kong and Singapore. Asia also has group - health & protection sales in the Philippines, Hong Kong and our joint ventures. To provide greater comparability across reporting periods, we exclude the impacts of foreign exchange translation from sales and gross flows. There is no directly comparable IFRS measure.

Third-party AUM. Third-party AUM is composed of retail, institutional, and other third-party assets, which includes general fund and segregated fund assets managed by our joint ventures. In Asset Management, third-party AUM includes Client assets for retail and institutional Clients, as well as capital raising, such as uncalled commitments and fund leverage in SLC Management. In Canada, third-party AUM includes Client assets in retail mutual fund products of Sun Life Global Investments. In Asia, third-party AUM includes Client assets in Hong Kong managed fund products, International asset management & wealth products, Philippines mutual and managed fund products, Aditya Birla Sun Life AMC Limited equity and fixed income mutual fund products, Sun Life Everbright Asset Management products and our joint ventures’ general fund and segregated fund assets based on our proportionate equity interest. There is no directly comparable IFRS financial measure.

Total weighted premium income ("TWPI"). This measure consists of 100% renewal premiums, 100% of first year premiums, and 10% of single premiums. In contrast to sales, which only includes premiums from new business, TWPI includes renewal premiums, reflecting the strength of the in-force block and providing a better understanding of both new and existing business. There is no directly comparable IFRS measure.

Underlying dividend payout ratio. This is the ratio of dividends paid per share to diluted underlying EPS for the period. The ratio is utilized during the medium-term capital budgeting process to inform our planned capital initiatives. We target an underlying dividend payout ratio of between 40% and 50% based on underlying EPS. For more information, see section J - Capital and Liquidity Management in the 2024 Annual MD&A.

Underlying effective tax rate. This measure is calculated using the pre-tax underlying net income and the income tax expense associated with it. Our statutory tax rate is normally reduced by various tax benefits, such as lower taxes on income subject to tax in foreign jurisdictions, a range of tax-exempt investment income, and other sustainable tax benefits. Our effective tax rate helps in the analysis of the income tax impacts in the period.

INTERIM CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Condensed Notes to the Interim Consolidated Financial Statements

(Unaudited, in millions of Canadian dollars, except for per share amounts and where otherwise stated. All amounts stated in U.S. dollars are in millions.)

1. General Information

Description of Business

Sun Life Financial Inc. ("SLF Inc.") is a publicly traded company domiciled in Canada and is the holding company of Sun Life Assurance Company of Canada ("Sun Life Assurance"). SLF Inc. and its subsidiaries are collectively referred to as "us", "our", "ours", "we", or "the Company".

Our Interim Consolidated Financial Statements and condensed notes have been prepared in accordance with International Accounting Standard ("IAS") 34 Interim Financial Reporting as issued by the International Accounting Standards Board ("IASB"). We have used accounting policies which are consistent with the accounting policies described in our 2024 Annual Consolidated Financial Statements, except as updated in Note 2 below. Our Interim Consolidated Financial Statements should be read in conjunction with our 2024 Annual Consolidated Financial Statements, as interim financial statements do not include all the information required in the annual consolidated financial statements which were prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the IASB.

2. Changes in Accounting Policies

Our material accounting policies and future changes in accounting policies that are not yet effective for us are disclosed in Notes 1 and 2 of our 2024 Annual Consolidated Financial Statements.

Other Changes in Accounting Policy

We have changed our accounting policy for certain joint ventures to disaggregate insurance finance income or expenses between net income and other comprehensive income ("OCI"). For these joint ventures, insurance finance income or expenses on our insurance contract liabilities were previously recorded through net income, while the corresponding invested assets were previously recorded at fair value through OCI ("FVOCI"). The invested assets and insurance contract liabilities are managed together and presenting insurance finance income or expenses through OCI reduces accounting mismatch. We account for these joint ventures using the equity method of accounting, whereby we recognize our share of net income in Net investment income (loss) in our Consolidated Statements of Operations and our share of OCI in our Consolidated Statements of Comprehensive Income (Loss). The impact of this change is not material to our share of net income or OCI in any individual prior period. We have processed an adjustment to increase opening Retained earnings by $213 and decrease Accumulated other comprehensive income by $213 retroactively to January 1, 2024.

3. Acquisition

Bowtie Life Insurance Company Limited

On July 15, 2025, we acquired an additional interest in Bowtie Life Insurance Company Limited ("Bowtie"), which increased our ownership interest, excluding dilution, by approximately 11% and resulted in a total ownership interest of 55.8%. Total consideration was cash of $55. Our previously held interest in Bowtie was remeasured to its fair value of $224, which resulted in a pre-tax gain of $176. The gain was recognized in Net investment income (loss) on the Consolidated Statements of Operations.

Bowtie is a Hong Kong-based virtual insurer with a prominent position in medical insurance, and will form part of our Asia business segment. The acquisition reinforces our long-term partnership with Bowtie, and is aligned with our strategy to enhance insurance accessibility.

The fair values of the identifiable assets and liabilities acquired were:


As at July 15, 2025
Intangible assets and Goodwill(1)	$	448
Net assets	60
Deferred tax liabilities	(8)
Total identifiable net assets at fair value	500
Non-controlling interests(2)	(221)
Existing ownership interest remeasured to fair value	(224)
Total consideration	$	55

(1) Goodwill primarily reflects the expected growth of the business. Goodwill is not tax deductible.

(2) We have elected to measure Non-controlling interests ("NCI") at fair value for this acquisition.

We have a contractual obligation to purchase existing equity from Bowtie's management, employees, and existing shareholders within six months of the acquisition date. A $14 liability, measured at fair value, was recognized in Other liabilities and offset by a reduction to Retained earnings.

Sun Life Financial Inc.

Third Quarter 2025

4. Segmented Information

We have five reportable business segments: Canada, United States ("U.S."), Asset Management, Asia, and Corporate. These business segments operate in the financial services industry and reflect our management structure and internal financial reporting. Asset Management includes the results of our MFS Investment Management ("MFS") and SLC Management business units. Corporate primarily includes our Corporate Support operations, which have investment income, expenses, capital, and other items not allocated to our other business groups.

Revenues from our business segments are derived primarily from life and health insurance, investment management and annuities, and mutual funds. Revenues not attributed to the strategic business units are derived primarily from Corporate investments and earnings on capital.

The expenses in each business segment may include costs or services directly incurred or provided on their behalf at the enterprise level. For other costs not directly attributable to one of our business segments, we use a management reporting framework that uses assumptions, judgments, and methodologies for allocating overhead costs and indirect expenses to our business segments.

Intersegment transactions consist primarily of internal financing agreements which are measured at fair values prevailing when the arrangements are negotiated. Intersegment investment income consists primarily of interest paid by U.S. to Corporate. Intersegment fee income is primarily asset management fees paid by our business segments to Asset Management. SLC Management collects fee income and incurs the operational expenses associated with the management of the general fund assets. Intersegment transactions are eliminated in the Consolidation adjustments column in the following tables.

Management considers its external Clients to be individuals and corporations. We are not reliant on any individual Client as none is individually significant to our operations.

Collateralized Loan Obligations Structure

Crescent Capital Group LP ("Crescent"), a subsidiary within our Asset Management business segment, issues and manages CLOs. Each CLO is a special purpose vehicle that owns a portfolio of investments, consisting primarily of senior secured loans, and issues various tranches of senior and subordinated notes to third parties for the purpose of financing the purchase of those investments. Assets of the special purpose vehicle, the senior secured loans, are included in Other financial invested assets and the associated liabilities, the senior and subordinated notes issued to third parties, are included in Other liabilities in our Consolidated Statements of Financial Position.

As at September 30, 2025, the carrying value of the assets related to CLOs are $6,305 (December 31, 2024 — $5,356), which consists of cash and accounts receivable of $805 (December 31, 2024 — $679) and loans of $5,500 (December 31, 2024 — $4,677). These underlying loans are mainly below investment grade.

As at September 30, 2025, the carrying value of the liabilities related to CLOs are $5,909 (December 31, 2024 — $5,028). Our maximum contractual exposure to loss related to the CLOs is limited to our investment of $314 (December 31, 2024 — $263) in the most subordinated tranche. The net unrealized loss incurred to date is $90.

5.A.ii Non-Financial Invested Assets

As at September 30, 2025, the carrying value and fair value of investment properties was $9,250 (December 31, 2024 — $9,290) and $9,250 (December 31, 2024 — $9,290), respectively.

(1) Included in Net investment income (loss) in our Consolidated Statements of Operations for Total invested assets measured at fair value.

(2) Total gains and losses in net income (loss) and OCI are calculated assuming transfers into or out of Level 3 occur at the beginning of the period. For an asset or liability that transfers into Level 3 during the reporting period, the entire change in fair value for the period is included in the table above. For transfers out of Level 3 during the reporting period, the change in fair value for the period is excluded from the table above.

(3) Investment properties included in net income is comprised of fair value changes on investment properties of $(94) and $(141) for the three and nine months ended September 30, 2025, respectively (September 30, 2024 — $(17) and $(285), respectively), net of amortization of leasing commissions and tenant inducements of $9 and $28 for the three and nine months ended September 30, 2025, respectively (September 30, 2024 — $22 and $41, respectively). As at September 30, 2025, we have used assumptions that reflect known changes in the property values including changes in expected future cash flows.

(4) Transfers into Level 3 occur when the inputs used to price the assets and liabilities lack observable market data, and as a result, no longer meet the Level 1 or 2 definitions at the reporting date. Transfers out of Level 3 occur when the pricing inputs become more transparent and satisfy the Level 1 or 2 criteria and are primarily the result of observable market data being available at the reporting date, thus removing the requirement to rely on inputs that lack observability.

(5) Foreign currency translation relates to the foreign exchange impact of translating Level 3 assets and liabilities of foreign subsidiaries from their functional currencies to Canadian dollars.

Total fee income		$	2,259		$	2,142		$	6,634		$	6,231

Distribution fees and Fund management and other asset-based fees are primarily earned in the Asset Management segment. Administrative service and other fees are primarily earned in the Canada and U.S. segments. The fee income by business segment is presented in Note 4.

9. Income Taxes

The Company’s effective income tax rate is generally lower than our statutory income tax rate of 27.8% due to various tax benefits, such as lower taxes on income subject to tax in foreign jurisdictions and a range of tax-exempt or low-taxed investment income.

Our effective income tax rate for the three and nine months ended September 30, 2025 was 18.0% and 19.1% compared to 13.1% and 17.8% for the three and nine months ended September 30, 2024. The effective income tax rate for the three and nine months ended September 30, 2025 was higher than the effective income tax rate for the three and nine months ended September 30, 2024, primarily due to lower tax-exempt or low-taxed investment income, which is partially offset by lower Global Minimum Tax ("GMT") expense in 2025.

In our Consolidated Statements of Operations, Income tax expense (benefit) has the following components:


	For the three months ended						For the nine months ended
	September 30 2025			September 30 2024			September 30 2025			September 30 2024

Current income tax expense (benefit)		$	361		$	339		$	851		$	852
Deferred income tax expense (benefit)		(101)			(124)			(151)			(184)
Total income tax expense (benefit)		$	260		$	215		$	700		$	668

The IASB issued amendments to IAS 12 Income Taxes in May 2023, which provided a mandatory temporary exception to the recognition and disclosure of information about deferred taxes relating to GMT, and we have applied this temporary exception. Our deferred taxes will not reflect impacts of GMT while the mandatory exception is applicable. The GMT rules applied to us effective January 1, 2024. The Canadian GMT legislation requires the ultimate parent entity of a group to pay top-up tax, on a jurisdiction-by-jurisdiction basis, on profits of its subsidiaries that are taxed below 15%. Some jurisdictions have enacted a Qualifying Domestic Minimum Top-Up Tax ("QDMTT") which requires the GMT top-up tax to be paid in the local jurisdiction rather than to the ultimate parent entity's jurisdiction. In response to the GMT rules, Bermuda enacted a Corporate Income Tax ("CIT") regime, including a corporate income tax rate of 15%, which applies to us effective January 1, 2025. The Bermuda CIT is not a QDMTT for the purposes of GMT. Top-up tax may still be payable by the ultimate parent entity under the Income Inclusion Rule, depending on the effective tax rate in Bermuda. Our other subsidiaries that are currently subject to a statutory tax rate or to a tax regime that could result in taxing profits at a rate below 15% include those in Hong Kong and Ireland, which have both enacted a QDMTT. Current income tax expense (benefit) for the three and nine months ended September 30, 2025 includes GMT income tax expense of $20 and $13. (September 30, 2024 — $34 and $64).

We renewed the NCIB to purchase up to 15 million of our common shares which commenced on August 29, 2024 and, was in effect until June 6, 2025 (the "2024 NCIB"). We repurchased approximately 14.4 million common shares under the 2024 NCIB. In June 2025, we renewed the NCIB to purchase up to 10.6 million common shares (the "2025 NCIB", and together with the 2024 NCIB, the "NCIBs"), representing an additional 10 million common shares approved by OSFI and the Toronto Stock Exchange (the "TSX"), and the remaining approximately 0.6 million common shares that we had not repurchased under the 2024 NCIB. The 2025 NCIB commenced on

June 9, 2025 and will continue until, at the latest, May 21, 2026.

We implemented an automatic repurchase plan with our designated broker in order to facilitate purchases of common shares under the NCIBs. Under the automatic repurchase plan, our designated broker is able to purchase common shares pursuant to the NCIBs at times when we ordinarily would not be active in the market due to applicable securities laws or self-imposed blackout periods. Any common shares purchased by us pursuant to the NCIBs will be cancelled or used in connection with certain equity settled incentive arrangements.

For the nine months ended September 30, 2025, we purchased and cancelled an aggregate of approximately 16.0 million common shares (September 30, 2024 — 8.5 million common shares) at an average price per share of $81.81 (September 30, 2024 — $71.00) for a total amount of $1,315 (September 30, 2024 — $606) under the NCIBs and incurred tax on net repurchases of equity of $25 (September 30, 2024 — $12). The total amount paid to purchase the shares pursuant to the NCIBs and the tax incurred is recorded in our Consolidated Statements of Changes in Equity. The amount allocated to Common shares is based on the average cost per common share and the amount paid above the average cost is allocated to Retained earnings.

10.B.ii Preferred Shares and Other Equity Instruments

On June 30, 2025, 2.7 million of the 5.0 million Class A Non-Cumulative Floating Rate Preferred Shares Series 9QR (the "Series 9QR Shares") were converted into Class A Non-Cumulative Rate Reset Preferred Shares Series 8R (the "Series 8R Shares") on a one-for-one basis. As a result, as of June 30, 2025, SLF Inc. has approximately 8.9 million Series 8R Shares and 2.3 million Series 9QR Shares issued and outstanding.

10.B.iii Other Capital Transactions

On September 11, 2025, SLF Inc. issued $1,000 principal amount of Series 2025-1 Subordinated Unsecured 4.14% Fixed/Floating Debentures due 2037. The net proceeds will be used for general corporate purposes, which may include supporting the acquisition of our remaining interests in the SLC Management subsidiaries BentallGreenOak LP and Crescent, investments in subsidiaries, repayment of indebtedness, and other strategic investments.

15. Legal and Regulatory Proceedings

We are regularly involved in legal actions, both as a defendant and as a plaintiff. Legal actions naming us as a defendant ordinarily involve our activities as a provider of insurance protection and wealth management products, as an investor and investment advisor, and as an employer. In addition, government and regulatory bodies in Canada, the U.S., the United Kingdom, and Asia, including federal, provincial, and state securities and insurance regulators, tax authorities, and other government authorities, from time to time, make inquiries and require the production of information or conduct examinations or investigations concerning our compliance with tax, insurance, securities, and other laws.

Provisions for legal proceedings related to insurance contracts, such as for disability and life insurance claims and the cost of litigation, are included in Insurance contract liabilities in our Consolidated Statements of Financial Position. Other provisions are established outside of the Insurance contract liabilities if, in the opinion of management, it is both probable that a payment will be required and a reliable estimate can be made of the amount of the obligation. Management reviews the status of all proceedings on an ongoing basis and exercises judgment in resolving them in such manner as management believes to be in our best interest.

Our significant legal proceedings and regulatory matters are disclosed in Note 22.G of our 2024 Annual Consolidated Financial Statements. There have been no significant updates to such legal and regulatory proceedings.
