• 公司董事会于2026年2月27日决议行使提前赎回权，赎回全部发行在外的“海优转债”。

3. 赎回价格及详细计算

赎回价格按照面值加当期应计利息，共101.2625元/张。应计利息的计算方式为：

• 票面利率：1.60%（2025年6月23日至2026年6月22日）
• 计息天数：288天（自2025年6月23日至2026年4月7日）
• 应计利息=100×1.60%×288/365 ≈ 1.2625元/张

4. 税务处理

• 个人投资者（含证券投资基金）须缴纳20%利息所得税，税后实际派发赎回金额为101.0100元/张。
• 居民企业自行纳税，实际派发赎回金额为101.2625元/张（税前）。

5. 影响及风险提示（对股价可能造成影响的重要信息）

• 赎回触发，转债市场将迎来流动性窗口，短期内有可能对转债价格和正股价格产生波动。
• 目前可转债二级市场价格（2026年3月20日收盘价为114.664元/张）远高于赎回价格（101.2625元/张），持有人若未及时转股或卖出，可能面临较大损失。
• 持有转债但未解除质押或冻结的投资者，需尽快解除，否则将被强制赎回，无法转股。
• 若投资者不符合科创板投资者适当性要求，转债无法转股，只能按赎回价格被强制赎回，存在损失风险。

特别提醒： “海优转债”持有人应在最后交易日前卖出或在最后转股日前完成转股操作，否则将被强制赎回，并可能承受价格差异带来的损失。

6. 投资者操作建议

• 建议投资者密切关注赎回进度和窗口期，及时决策，降低不必要损失。
• 有质押或被冻结情况的投资者，须尽快解除相关限制。

HIUV to Redeem and Delist “HIUV Convertible Bonds” – Urgent Notice for Investors

[March 23, 2026, Shanghai] Shanghai HIUV New Materials Co., Ltd. (Stock code: 688680, Bond code: 118008) announced its second notice regarding the redemption and delisting of “HIUV Convertible Bonds”. The company will exercise its right to redeem all outstanding convertible bonds early, and these bonds will be delisted from the Shanghai Stock Exchange on April 7, 2026. This move is significant for convertible bond holders and shareholders, with the following arrangements and risk warnings:

1. Redemption Arrangements and Key Dates

• Redemption Record Date: April 3, 2026
• Redemption Price: RMB 101.2625 per bond (including accrued interest)
• Redemption Payment Date: April 7, 2026
• Last Trading Day: March 31, 2026
• Last Conversion Day: April 3, 2026
• Delisting Date: April 7, 2026

Important Notice: As of market close on March 20, 2026, only 7 trading days remain until the last trading day and 10 days until the last conversion day. Investors must complete conversion or sell their bonds before these deadlines to avoid forced redemption and potential losses.

2. Redemption Clause Triggered – Background

• The company’s A-share price closed at no less than 130% of the conversion price (RMB 60.84/share) on 15 trading days between Jan 22 and Feb 27, 2026, triggering the conditional redemption clause.
• The board resolved on Feb 27, 2026, to exercise the early redemption right and redeem all outstanding “HIUV Convertible Bonds”.

3. Redemption Price and Calculation

The redemption price is par plus accrued interest, totaling RMB 101.2625 per bond. Accrued interest calculation:

• Coupon Rate: 1.60% (from June 23, 2025 to June 22, 2026)
• Days Counted: 288 (from June 23, 2025 to April 7, 2026)
• Accrued Interest = 100 × 1.60% × 288 / 365 ≈ RMB 1.2625 per bond

4. Tax Treatment

• Individual investors (including funds) pay 20% income tax on interest; net redemption received is RMB 101.0100 per bond.
• Resident enterprises handle their own taxes; gross redemption is RMB 101.2625 per bond.
• Qualified foreign institutional investors (QFII, RQFII) are temporarily exempt from enterprise income tax and VAT; gross redemption is RMB 101.2625 per bond.

5. Impact and Risk Warnings (Material for Share Price)

• Redemption will affect bond market liquidity and may cause short-term volatility in both bond and underlying stock prices.
• The current secondary market price (RMB 114.664 per bond as of March 20, 2026) is much higher than the redemption price (RMB 101.2625 per bond). Failure to sell or convert in time can cause significant losses.
• Bondholders with pledged or frozen bonds must lift such restrictions before the deadline, or they will be forcibly redeemed and unable to convert.
• If holders do not meet STAR Market investor suitability requirements, the bonds cannot be converted and will be redeemed at the redemption price, which may result in losses.

Special Reminder: Bondholders should sell or convert their bonds before the last trading or conversion date to avoid forced redemption and potential losses due to the price gap.

6. Investor Recommendations

• Monitor redemption progress and deadlines closely to avoid unnecessary losses.
• Clear any pledges or freezes on bonds promptly.
