[FWP] Bank of Nova Scotia Free Writing Prospectus

Rhea-AI Filing Summary

The Bank of Nova Scotia (BNS) has filed an Issuer Free Writing Prospectus for a new structured note offering, the Performance Leveraged Upside SecuritiesSM (PLUS), linked to the EURO STOXX 50® Index (SX5E). The notes are senior unsecured debt under the bank’s Senior Note Program, Series A. Each PLUS has a stated principal of $1,000, an issue price of $1,000, and requires a minimum purchase of one unit. They are expected to price on 17 July 2025, settle on 22 July 2025, and mature on 4 November 2026 (≈ 16-month tenor), subject to standard market-disruption adjustments.

Payment at maturity is entirely contingent on the index performance:

• Upside: 300% leveraged participation when the final index value exceeds the initial value, capped at a 21.40 % maximum gain (maximum payment = $1,214).
• Downside: full 1-for-1 exposure to negative index moves; investors can lose up to their entire principal.

There is no periodic interest and the notes will not be listed on any exchange. Initial estimated value on the pricing date is projected at $941–$971, reflecting upfront fees (dealer commission $22.50 per note) and hedging costs. All cash flows are subject to BNS’s credit risk.

The filing highlights extensive risk factors, including: lack of principal protection, liquidity constraints, limited secondary market making, potential conflicts of interest from BNS/SCUSA hedging, sensitivity to non-U.S. market movements, and uncertain Canadian & U.S. tax treatment. Investors are directed to review the preliminary pricing supplement and related prospectus documents on the SEC’s EDGAR site (CIK 0000009631) before investing.

Positive

• 300 % leverage on positive EURO STOXX 50 returns offers enhanced upside versus direct index investment, up to a 21.4 % cap.
• Short 16-month tenor provides defined investment horizon and quicker capital turnover compared with typical 3-5-year structured notes.

Negative

• No principal protection; investors can lose 100 % of capital if the index falls 100 %.
• Maximum gain capped at 21.4 %, limiting participation in strong bull markets.
• Unsecured debt status exposes holders to Bank of Nova Scotia credit risk.
• Limited liquidity; notes will not be exchange-listed and dealer market-making is discretionary.

Insights

Structured-Products Analyst

TL;DR: BNS launches capped-return EURO STOXX 50 note; high leverage but full downside risk, limited impact on bank fundamentals.

The PLUS provide 3× upside exposure, yet gains stop at 21.4 %. With no coupon, investors rely solely on final index level, accepting complete capital risk. Estimated fair value (≈ 94–97 % of face) implies an upfront cost of 3–6 %, typical for retail-targeted structured notes. From a credit perspective, issuance marginally extends BNS’s unsecured debt stack but is immaterial relative to its multi-billion funding base; therefore, I view the news as neutral to the equity and credit thesis. For buyers, the instrument may appeal in moderately bullish but range-bound scenarios; however, the capped upside versus unbounded downside tilts the risk-reward unfavorably if the index underperforms.

Risk Analyst

TL;DR: Product carries full market and issuer credit risk; liquidity and valuation transparency are limited.

The note embeds significant tail risk: every 1 % decline in SX5E cuts redemption value by 1 %, with no floor. Secondary trading depends on SCUSA discretion, often at steep discounts to theoretical value. The 300 % leverage heightens volatility of mark-to-market pricing, potentially triggering early losses for investors who exit before maturity. Conflicts of interest exist because BNS and affiliates hedge the exposure and act as calculation agent. From a systemic viewpoint, issuance size is small; thus, market impact is negligible, leading to a neutral impact rating.
