Bigbank Fortifies Capital with Strategic €3M AT1 Bond Placement

TALLINN, ESTONIA – February 12, 2026 – Bigbank AS, an Estonian-owned commercial bank, has successfully raised EUR 3 million through a targeted private placement of Additional Tier 1 (AT1) bonds, a move that enhances its capital structure as it pursues an ambitious growth strategy across Europe.

The bank announced that the offering consisted of 30 notes, each with a nominal value of 100,000 euros, which were allocated to just two investors. This discreet but significant transaction underscores continued investor confidence and provides the financial institution with a stronger buffer to support its expanding operations.

Understanding the Instrument: A Look at AT1 Bonds

The choice of an Additional Tier 1 instrument is a highly strategic one for any financial institution. Born from the regulatory overhaul following the 2008 global financial crisis, AT1 bonds are a specialized form of capital designed to bolster a bank's resilience. Governed by Basel III and European Banking Authority (EBA) guidelines, these instruments serve as a crucial loss-absorbing cushion.

Unlike traditional debt, AT1 bonds are perpetual, meaning they have no fixed maturity date. They are designed to absorb losses during times of severe financial stress. If a bank’s core capital ratio—its Common Equity Tier 1 (CET1)—falls below a predetermined trigger point, these bonds can be automatically written down or converted into equity. This mechanism protects depositors and prevents the need for taxpayer-funded bailouts by forcing the bank's creditors to share in the losses.

For investors, this inherent risk is balanced by a significantly higher yield compared to more senior bank debt. However, the coupon payments are discretionary and non-cumulative, meaning the bank can skip them without triggering a default, particularly if it is not meeting profitability or capital thresholds. This makes them a high-risk, high-reward asset class, typically attracting sophisticated institutional investors and high-net-worth individuals who understand the complex risk profile. Bigbank's ability to place these instruments, even in a targeted manner, signals access to this specialized corner of the capital markets.

Balancing Growth Ambitions with Financial Prudence

This EUR 3 million capital injection arrives at a pivotal moment for Bigbank. The institution is in the midst of a multi-year strategy aimed at transforming from a consumer loan specialist into a full-service digital bank. This includes expanding into everyday banking with current accounts and payment services, as well as growing its mortgage and corporate loan portfolios across its nine operating countries.

This growth has been rapid. The bank's total assets have swelled from EUR 2.78 billion at the end of 2024 to EUR 3.2 billion by November 2025, with its loan portfolio showing similar momentum. While expansion is key to its strategy, it also brings heightened regulatory scrutiny and risk management challenges.

Rating agency Moody's has taken note of this trajectory. In June 2024, it downgraded Bigbank's long-term deposit rating to Ba1 from Baa3, citing concerns over aggressive growth, a corresponding deterioration in asset quality, and declining profitability metrics. The agency later revised its outlook on the rating to negative in May 2025, signaling continued pressure.

Against this backdrop, the AT1 issuance can be seen as a proactive measure to fortify its capital base. While EUR 3 million is a modest sum compared to its total equity of EUR 298 million, it specifically strengthens the Additional Tier 1 layer, which is a critical component of its total loss-absorbing capacity. This follows a similar, smaller AT1 issuance of EUR 2.54 million in September 2025, indicating a consistent effort to optimize its capital structure and build buffers that can support its balance sheet growth in a prudent manner.

The Strategic Logic of a Private Placement

Opting for a private placement with only two investors, rather than a broad public offering, carries its own strategic logic. This targeted approach allows for faster execution, discretion, and the ability to negotiate terms directly with investors who have a deep understanding of the bank's credit story and the nature of AT1 instruments.

For the issuer, it avoids the complexities and costs of a public listing while securing capital from committed partners. For the two investors involved, it provides an opportunity to secure a significant allocation of a high-yielding instrument that may not be available on the open market. This approach is particularly suitable for smaller, specialized issuances where the cost of a public offering might be prohibitive.

The transaction also reflects broader trends in the European financial markets. The appetite for AT1 bonds has remained remarkably robust, even after the market was shaken by the write-down of Credit Suisse's AT1 bonds in 2023. European banks issued a record volume of over $45 billion in new AT1s in 2024, driven by investors' search for yield in a world of strong bank fundamentals. While much of this activity involved refinancing by large institutions, the continued demand creates opportunities for banks of all sizes, like Bigbank, to tap this market for strategic funding.

This successful placement demonstrates that even with a non-investment-grade rating and a negative outlook, Bigbank's growth narrative and financial profile remain compelling to sophisticated investors willing to take on calculated risk for attractive returns. It reinforces the bank's position as a dynamic player in the Baltic financial sector, capable of leveraging complex financial tools to fuel its long-term vision of becoming a leading digital financial service provider in its core markets.
