Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Total Bond Market Trust (Series NAV/JAGUX) returned 6.91% for the year ended December 31, 2025. The fixed income market delivered broad gains in 2025 as attractive yields, tighter credit spreads, and strong performance across U.S. and emerging market sectors supported returns. The U.S. Federal Reserve’s three late-year rate cuts contributed to a steepening yield curve, lowering short-term yields while longer maturities rose amid fiscal and tariff related volatility, further boosting bond performance.
TOP PERFORMANCE CONTRIBUTORS
Yield positioning and interest payments | The fund was well positioned for a steepening of the yield curve which occurred during the period. Interest payments were significant contributors to return.
Fixed income securities | U.S. agency mortgage-backed securities and investment-grade corporate bonds were meaningful contributors to absolute performance.
TOP PERFORMANCE DETRACTORS
U.S. Treasuries | The fund’s portfolio allocation in U.S. Treasury securities detracted from performance on an absolute basis.
The views expressed in this report are those of the portfolio management team and are subject to change. They are not meant as investment advice.

Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Core Bond Trust (Series I/JADKX) returned 6.94% for the year ended December 31, 2025. Investment-grade fixed income bonds performed well during the period, with attractive yields, the resumption of interest rate cuts by the Federal Reserve late in the year and continued strength in U.S. economic conditions. The yield curve steepened considerably, while credit and mortgage spreads tightened on fundamental improvement and strong demand.
TOP PERFORMANCE CONTRIBUTORS
Mortgage-backed securities | Positions in agency mortgage-backed securities, including passthroughs and collateralized mortgage obligations (CMOs), were among the largest contributors to performance. Mortgage-backed securities had a strong year as lower interest rates, a steeper yield curve, and falling interest rate volatility all supported valuations and demand.
Corporate bonds | Holdings in corporate bonds across industrial, utility, and financial subsectors contributed to performance. Corporate bonds benefited from resilient economic conditions, prospects for deregulation, and strong demand from domestic and foreign investors.
TOP PERFORMANCE DETRACTORS
Long-dated Treasuries | Certain holdings in longer-dated Treasuries detracted from performance, as the yield curve steepened and long-term interest rates actually rose slightly during the period.
Oracle Corp. | Positioning in Oracle Corp. detracted as investors grew more concerned about the company’s level of investment in artificial intelligence initiatives.

The yield curve steepened considerably, while credit and mortgage spreads tightened on fundamental improvement and strong demand.
TOP PERFORMANCE CONTRIBUTORS
Mortgage-backed securities | Positions in agency mortgage-backed securities, including passthroughs and collateralized mortgage obligations (CMOs), were among the largest contributors to performance. Mortgage-backed securities had a strong year as lower interest rates, a steeper yield curve, and falling interest rate volatility all supported valuations and demand.
Corporate bonds | Holdings in corporate bonds across industrial, utility, and financial subsectors contributed to performance. Corporate bonds benefited from resilient economic conditions, prospects for deregulation, and strong demand from domestic and foreign investors.
TOP PERFORMANCE DETRACTORS
Long-dated Treasuries | Certain holdings in longer-dated Treasuries detracted from performance, as the yield curve steepened and long-term interest rates actually rose slightly during the period.
Oracle Corp. | Positioning in Oracle Corp. detracted as investors grew more concerned about the company’s level of investment in artificial intelligence initiatives.

Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Opportunistic Fixed Income Trust (Series NAV/JAEKX) returned 9.60% for the year ended December 31, 2025. Most fixed income sectors generated positive total returns during the trailing twelve months as coupon income and periods of spread tightening helped offset the impact of volatile and higher global sovereign yields in some regions. Most spread sectors produced positive excess returns over duration-equivalent government bonds, with higher-yielding and emerging market sectors leading the outperformance. Political instability and policy uncertainty were prominent, with leadership changes in France and Japan, and the US experiencing its longest government shutdown on record.
TOP PERFORMANCE CONTRIBUTORS
Duration and yield curve | At the aggregate portfolio level, duration and yield curve positioning was one of the top contributors to positive total returns overall. Currency and credit exposure were also additive to results.
Strategic sector | Positive total returns were driven by strategic sector positions. Within the strategic sector, emerging market opportunities positioning was the largest positive contributor, in particular exposure to local debt had a favorable impact.
TOP PERFORMANCE DETRACTORS
Relative value | Within the fund’s relative value theme, exposure to discretionary macro rates had a negative impact on performance.
Tactical | Our duration management strategies within the tactical return driver detracted.

Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Active Bond Trust (Series I/JAHFX) returned 7.39% for the year ended December 31, 2025. The fixed income market delivered broad gains in 2025 as attractive yields, tighter credit spreads, and strong performance across U.S. and emerging market sectors supported returns. The U.S. Federal Reserve’s three late-year rate cuts contributed to a steepening yield curve, lowering short-term yields while longer maturities rose amid fiscal and tariff related volatility, further boosting bond performance.
TOP PERFORMANCE CONTRIBUTORS
Yield positioning and interest payments | The fund was well positioned for a steepening of the yield curve which occurred during the period. Interest payments were significant contributors to return.
Fixed income assets | Agency mortgage-backed securities were meaningful contributors to absolute performance.
TOP PERFORMANCE DETRACTORS
U.S. Treasuries | The fund’s portfolio allocation in U.S. Treasury securities detracted from performance on an absolute basis.
The views expressed in this report are those of the portfolio management team and are subject to change. They are not meant as investment advice.

Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Active Bond Trust (Series NAV/JAHDX) returned 7.56% for the year ended December 31, 2025. The fixed income market delivered broad gains in 2025 as attractive yields, tighter credit spreads, and strong performance across U.S. and emerging market sectors supported returns. The U.S. Federal Reserve’s three late-year rate cuts contributed to a steepening yield curve, lowering short-term yields while longer maturities rose amid fiscal and tariff related volatility, further boosting bond performance.

Material Fund Changes
At a meeting held on September 24-26, 2024, the Board of Trustees of the Trust (the Board) approved changes to the fund’s subadvisory arrangements such that effective February 7, 2025, Western Asset Management Company, LLC was replaced by Manulife Investment Management (US) LLC as the fund’s subadvisor.
At the same meeting, the Board approved a change in the fund’s management fee schedule effective February 7, 2025 whereby the annual rate is as follows: a) 0.625% of the first $75 million of aggregate net assets; b) 0.5625% of the next $75 million of aggregate net assets; c) 0.500% of the next $350 million of aggregate net assets; d) 0.475% of the next $2 billion of aggregate net assets; and e) 0.450% of the excess over $2.5 billion of aggregate net assets. Aggregate net assets include net assets of the fund and John Hancock High Yield Fund, a series of John Hancock Bond Trust.
Effective February 7, 2025, the fund’s investment objective is as follows: The fund seeks high current income. Capital appreciation is a secondary goal.
Additionally, effective February 7, 2025, the following risks were added to the fund’s “Principal Risks” in the “Fund Summary” section of the Prospectus for the fund: Default debt risk; ESG integration risk; High portfolio turnover risk; Illiquid and restricted securities risk; Large company risk; Small and mid-sized company risk; and U.S. government agency obligations risk. Repurchase agreements risk was removed.
In connection with the Board actions described above, the principal investment strategies of the fund have been revised. The purpose of these changes was to align the fund with the investment approach of the new subadvisor. Specifically, the strategies were revised to reflect the new subadvisor’s focus on industry allocation and securities selection, deciding which types of industries to emphasize at a given time and then which individual securities to buy. This includes a top-down analysis to determine which industries may benefit from current and future changes in the economy and bottom-up research to find securities that appear comparatively undervalued.
This is a summary of certain changes to the fund since 1-1-25 . For more complete information, please refer to the fund’s prospectus. The currently effective prospectus is available at dfinview.com/johnhancock?site=funds or by calling 800-344-1029 for John Hancock Variable Annuities and 800-732-5543 for John Hancock Variable Life Insurance.

Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
High Yield Trust (Series I/JAELX) returned 7.46% for the year ended December 31, 2025. The fixed income market delivered broad gains in 2025 as attractive yields, tighter credit spreads, and strong performance across U.S. and emerging market sectors supported returns. The U.S. Federal Reserve’s three late-year rate cuts contributed to a steepening yield curve, lowering short-term yields while longer maturities rose amid fiscal and tariff related volatility, further boosting bond performance.
TOP PERFORMANCE CONTRIBUTORS
Yield positioning and interest payments | The fund was well positioned for a steepening of the yield curve which occurred during the period. Interest payments were significant contributors to return.
Fixed income securities | Holdings in high yield and investment-grade corporate bonds were meaningful contributors to performance.
TOP PERFORMANCE DETRACTORS
Bank loans | Bank loans were the only asset category that detracted from absolute fund performance.
The views expressed in this report are those of the portfolio management team and are subject to change. They are not meant as investment advice.

Material Fund Change [Text Block]
Material Fund Changes
At a meeting held on September 24-26, 2024, the Board of Trustees of the Trust (the Board) approved changes to the fund’s subadvisory arrangements such that effective February 7, 2025, Western Asset Management Company, LLC was replaced by Manulife Investment Management (US) LLC as the fund’s subadvisor.
At the same meeting, the Board approved a change in the fund’s management fee schedule effective February 7, 2025 whereby the annual rate is as follows: a) 0.625% of the first $75 million of aggregate net assets; b) 0.5625% of the next $75 million of aggregate net assets; c) 0.500% of the next $350 million of aggregate net assets; d) 0.475% of the next $2 billion of aggregate net assets; and e) 0.450% of the excess over $2.5 billion of aggregate net assets. Aggregate net assets include net assets of the fund and John Hancock High Yield Fund, a series of John Hancock Bond Trust.
Effective February 7, 2025, the fund’s investment objective is as follows: The fund seeks high current income. Capital appreciation is a secondary goal.
Additionally, effective February 7, 2025, the following risks were added to the fund’s “Principal Risks” in the “Fund Summary” section of the Prospectus for the fund: Default debt risk; ESG integration risk; High portfolio turnover risk; Illiquid and restricted securities risk; Large company risk; Small and mid-sized company risk; and U.S. government agency obligations risk. Repurchase agreements risk was removed.
In connection with the Board actions described above, the principal investment strategies of the fund have been revised. The purpose of these changes was to align the fund with the investment approach of the new subadvisor. Specifically, the strategies were revised to reflect the new subadvisor’s focus on industry allocation and securities selection, deciding which types of industries to emphasize at a given time and then which individual securities to buy. This includes a top-down analysis to determine which industries may benefit from current and future changes in the economy and bottom-up research to find securities that appear comparatively undervalued.
This is a summary of certain changes to the fund since 1-1-25 . For more complete information, please refer to the fund’s prospectus. The currently effective prospectus is available at dfinview.com/johnhancock?site=funds or by calling 800-344-1029 for John Hancock Variable Annuities and 800-732-5543 for John Hancock Variable Life Insurance.

Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Investment Quality Bond Trust (Series I/JADUX) returned 6.97% for the year ended December 31, 2025. Most fixed income sectors generated positive total returns during the year, as coupon income and periods of spread tightening helped offset the impact of volatile, and in some regions, higher global sovereign yields.
TOP PERFORMANCE CONTRIBUTORS
Yield positioning and interest payments | The portfolio’s duration positioning was the largest contributor to performance over the period. Interest payments were significant contributors to return.
Allocation to structured finance sectors | Non-agency mortgage-backed securities and commercial mortgage-backed securities were meaningful contributors.
Agency mortgage-backed securities (MBS) | Exposure to MBS passthroughs also aided results.
TOP PERFORMANCE DETRACTORS
No detractors | At a time of broadly positive performance for the world financial markets, no asset categories detracted from absolute performance.
The views expressed in this report are those of the portfolio management team and are subject to change. They are not meant as investment advice.

Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Strategic Income Opportunities Trust (Series I/JESNX) returned 7.51% for the year ended December 31, 2025. The fixed income market delivered broad gains in 2025 as attractive yields, tighter credit spreads, and strong performance across U.S. and emerging market sectors supported returns. The U.S. Federal Reserve’s three late-year rate cuts contributed to a steepening yield curve, lowering short-term yields while longer maturities rose amid fiscal and tariff related volatility, further boosting bond performance.
TOP PERFORMANCE CONTRIBUTORS
Yield positioning and interest payments | The fund was well positioned for a steepening of the yield curve which occurred during the period. Interest payments were significant contributors to return.
Fixed income securities | Both investment-grade corporate bonds and high yield corporate bonds were meaningful contributors to absolute performance.
TOP PERFORMANCE DETRACTORS
Emerging market credit | The fund's emerging market credit positions detracted from absolute performance.
Municipal bonds | Municipal bond securities also detracted from absolute performance.

Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Short Term Government Income Trust (Series I/JAJPX) returned 5.14% for the year ended December 31, 2025. The fixed income market delivered broad gains in 2025 as attractive yields, tighter credit spreads, and strong performance across U.S. and emerging market sectors supported returns. The U.S. Federal Reserve’s three late-year rate cuts contributed to a steepening yield curve, lowering short-term yields while longer maturities rose amid fiscal and tariff related volatility, further boosting bond performance.
TOP PERFORMANCE CONTRIBUTORS
Yield positioning and interest payments | The fund was well positioned for a steepening of the yield curve which occurred during the period. Interest payments were significant contributors to return.
Fixed income securities | Agency mortgage-backed securities also contributed to overall performance.
TOP PERFORMANCE DETRACTORS
U.S. Treasuries | U.S. Treasuries detracted from absolute performance.

Factors Affecting Performance [Text Block]
Management’s Discussion of Fund Performance

SUMMARY OF RESULTS
Ultra Short Term Bond Trust (Series I/JAGJX) returned 4.29% for the year ended December 31, 2025. The fixed income market delivered broad gains in 2025 as attractive yields, tighter credit spreads, and strong performance across U.S. and emerging market sectors supported returns. The U.S. Federal Reserve’s three late-year rate cuts contributed to a steepening yield curve, lowering short-term yields while longer maturities rose amid fiscal and tariff related volatility, further boosting bond performance.
