Bond issuer A2A fails to meet SLB's set target, instigating a 25 basis points coupon increase
In the realm of sustainable finance, the impact of missed targets on corporate bond coupon rates has become a significant concern, particularly as the EU Green Bond Regulation introduces higher transparency and compliance standards. This article explores the case of A2A, an Italian multi-utility company that issued a Sustainability-Linked Bond (SLB) in 2022, and the broader market context and insights that can be gleaned from other SLB issuers.
A2A, a pioneer in sustainable finance, issued both a European Green Bond and sustainability-linked bonds. While the focus has been on A2A’s European Green Bond, the SLB market offers valuable insights, as specific coupon step-up data for A2A’s SLB is not readily available.
When an issuer misses a sustainability target linked to an SLB, the coupon rate typically increases, a financial disincentive to encourage compliance with sustainability goals. For instance, the Italian oil major Eni faces a potential cumulative coupon step-up of €48.75 million across several SLBs if its targets are missed.
The introduction of the EU Green Bond Regulation increases the scrutiny and consequences for missed targets. Major institutional investors and central banks are tilting their portfolios towards firms with stronger sustainability credentials. For example, the European Central Bank now reinvests maturing corporate bond proceeds towards companies with lower greenhouse gas emissions.
A2A missed a renewable energy target associated with its 2022 SLB. The missed target triggered a 25bps step-up in the bond's coupon rate. AFII's head of research, Josephine Richardson, noted early signs of A2A missing the target and highlighted A2A's strategy updates in early 2024 that were on track to undershoot the renewable energy target of the bond in question.
The market's awareness and efficiency in pricing in missed targets are increasing. The pricing in of missed targets and the imposition of costs on companies like A2A is arguably linked to the credibility and ambition of SLB targets. In 2023, another Italian energy company, Enel, also missed its SLB target, and markets responded with price shifts reflecting the coupon rate increases for ten SLBs (AFII research).
The timing issue affecting the SLB market prices in the consequence of a missed SLB target is becoming more apparent as the market matures and evolves. The report's auditor statement for A2A was dated 31 March 2025, and the annual coupon is paid on 16 March, implying that the higher coupon will only accrue by that date next year.
The SLB market's maturing efficiency is demonstrated by the market's response to A2A and Enel's missed SLB targets. A2A's chief financial officer, Luca Moroni, stated that the issuance confirmed A2A as a reference institution in the development of sustainable finance instruments.
In conclusion, missed green bond or SLB targets have a clear and immediate financial impact on corporate bond coupon rates, increasing borrowing costs for issuers through predefined step-up mechanisms. The evolution of green and sustainability-linked bond markets signals a sustained shift toward greater accountability, transparency, and financial consequences for issuers regarding their environmental performance. The NZI Charities and Endowments Summit, held in London on 12/06/2026, will undoubtedly continue discussions on these pressing issues in sustainable finance.
Science and environmental science have gained significant importance in the context of sustainable finance, particularly as they relate to climate-change and corporate sustainability targets. For instance, the pricing of missed targets in Sustainability-Linked Bonds (SLBs) is influenced by the extent of a company's progress towards its environmental goals, as demonstrated by A2A's experience in 2022 when a missed renewable energy target triggered a 25bps step-up in the bond's coupon rate. This highlights the business implications of environmental performance in the finance sector.
