Convertible bond restructuring reduces dilution; Bernstein maintains Outperform rating on Horizon Robotics

Overview

This report focuses on the convertible bond restructuring announced by Horizon Robotics on July 23, 2026, and its expanded L3/L4 autonomous driving cooperation with Volkswagen. Bernstein views both developments positively: the convertible bond restructuring avoids the dilution and selling pressure that could have arisen under the original arrangement for the portion exceeding VW's 9.9% ownership threshold, while lowering financing costs through a new zero-coupon convertible bond; on the cooperation side, VW's commitment to the L3/L4 project validates the commercial value of Horizon Robotics' full-stack autonomous driving technology.

Core views

The report's core view is that the market may have misread the transaction's impact, as reflected in the 3.8% decline after the announcement. Under the original CLA arrangement, about 716mn shares exceeding VW's 9.9% threshold could have been placed with financial investors, resulting in about 4.9% potential dilution and selling pressure; after the restructuring, the excess shares are replaced with a new CB, whose potential dilution is about 3.9%, equivalent to a reduction of about 1.0 percentage point in dilution. Meanwhile, the old interest-bearing CB is replaced by a zero-coupon, zero-yield CB, which is expected to save about USD 20Mn in interest expenses.

Analysis framework

The report uses event-driven and transaction-structure analysis, comparing the original CLA terms, revised equity capital changes, cash payments, implied buyback discount, interest savings, and the new CB terms, while also assessing the investment implications in conjunction with how VW's L3/L4 cooperation validates Horizon Robotics' technological moat and business model. In terms of valuation, Bernstein applies a 10.3x EV/Sales multiple to its 2BF (2H27-1H28) sales forecast of RMB 11.5Bn to derive a target price of HKD 10.

Methodology notes

• Valuation methodsEV/Sales multiple method

  The report states that the HKD 10 target price is based on 10.3x EV/Sales, corresponding to a 2BF (2H27-1H28) sales forecast of RMB 11.5Bn.

• Capital structure analysisConvertible bond dilution scenario comparison

  Comparing the impact of the original conversion arrangement versus the post-restructuring new CB arrangement on equity dilution, interest costs, and selling pressure

  The report compares about 4.9% potential dilution under the original CLA with about 3.9% potential dilution under the new CB, concluding that dilution is reduced by about 1.0 percentage point.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Horizon Robotics (9660.HK)

  Core covered name

  Strengths

  Convertible bond restructuring reduces dilution and interest costs; cooperation with VW validates L3/L4 autonomous driving technology; commercialization paths include BPU, algorithm IP, standardized chips, full-stack solutions, and JV.

  Weaknesses

  The post-announcement share price decline suggests the market may still have concerns about the transaction structure; the business still depends on smart driving penetration and delivery pace from major customers.

  Comparison

  Compared with the original CLA arrangement, the new structure reduces potential dilution with a higher conversion price and a zero-coupon CB, while also reducing the selling pressure from potential placements to financial investors in the near term.

  Risks

  Smart driving penetration falls short of expectations, OEM in-house development gains a higher-than-expected share, or shipments/deployments by major customers are delayed.

• Volkswagen / CARIAD / VOW.DE

  Strategic partner and related party to the convertible bond

  Strengths

  Extended the lock-up period for all holdings by 12 months and expanded L3/L4 cooperation, reinforcing the signal of long-term partnership.

  Weaknesses

  Execution of the cooperation still depends on VW China's autonomous driving architecture, CARIZON licensing, and the deployment progress of follow-up vehicle models.

  Comparison

  Instead of potentially handling the excess shares through third parties, the parties moved to reduce dilution and selling pressure through an amended CLA and a new CB arrangement.

  Risks

  If initial L3 deliveries or L4 application rollouts progress more slowly than the target timetable, it could pressure the validation effect of the cooperation and commercialization expectations.

Impact & implications

The investment implication of this transaction is that it simultaneously improves the capital structure, reduces potential dilution, weakens short-term selling pressure, and signals deeper cooperation with VW. Bernstein believes this supports shareholder value protection and also shows that even as OEMs strengthen in-house development, Horizon Robotics can remain commercially relevant through underlying technology, chips, algorithm IP, full-stack solutions, and JVs.

Risks

• The increase in smart driving penetration may fall short of expectations.
• OEM in-house autonomous driving solutions may gain a higher-than-expected share.
• Shipments or deployments by major customers may be delayed, causing revenue growth to miss expectations.
• The new CB may still create about 3.9% potential dilution if converted in the future.

What to watch

• Follow-up milestones in the L3/L4 autonomous driving projects between VW and Horizon Robotics, especially the initial L3 delivery in 2H27.
• Commercial execution after CARIZON obtains licensing for Horizon Robotics' AI foundation model, C7H SoC architecture, and GAIA world model data platform.
• Changes in the premium of the new CB conversion price of HKD 5.55 relative to the share price and the potential conversion risk.
• Whether the market reassesses the positive impact of the convertible bond restructuring on dilution, selling pressure, and interest expenses.
