Mia Ihamuotila

Legal Tech & Design Lawyer

I specialise in data protection, legal technology and legal design and co-lead our legal technology and design team. My team produces innovative solutions that improve the quality and efficiency of legal services. As a lawyer, I am innovative and creative, focusing on change management and the implementation of new perspectives and practices, such as user-centricity and artificial intelligence, in our field.

I graduated from the University of Helsinki in the spring of 2024. During my studies, I worked in law firms and as a consultant in legal technology and legal design and also managed client projects. My master’s thesis dealt with the interpretation of data protection legislation and the comprehensibility, transparency and user-centricity of privacy statements and was based on empirical research and user experiences. My research showed that comprehensibility and transparency increase thanks to design methods.

I actively participate in the development of our business, project management and innovation processes. I speak at national and international legal innovation conferences, through which I have gained extensive insights into the topics. Additionally, I have acquired expertise in the fields of design, psychology and information processing.

My team also includes legal technology trainees, with whom we take care of our digital tools. Our team’s tasks include document automation and training our staff in the use of legal technology.

In my work, I particularly enjoy being involved in developing new solutions that meet the changing needs of the business. I am social and cooperative, and I value close and interdisciplinary collaboration both within the organisation and with external stakeholders. It is important to me to be part of a dynamic and forward-looking work community where we can create meaningful changes together.

We advised Aktia Bank Plc on the issuance of an EUR 80 million Additional Tier 1 (AT1) bond. The bond pays a fixed interest rate of 6.75 per cent semi-annually. The bond is perpetual, and Aktia has the right to redeem or repurchase it in accordance with the terms of the bond, subject to certain conditions. The bond was issued on 1 April 2026.

The EU Follow-on prospectus was introduced on 5 March 2026 with an update to the Prospectus Regulation (EU) No. 2017/1129. The EU Follow-on prospectus is a new type of prospectus that can be used, among others, by issuers whose securities have been admitted to trading on a regulated market continuously for at least the 18 months preceding the offer to the public or the admission to trading on a regulated market of the new securities. A follow-on prospectus is simpler than a so-called traditional prospectus, and it is intended to avoid repeating information that the issuer has already disclosed. Nordea Bank Abp acts as the sole structuring advisor for the issue of the Notes. Nordea Bank Abp, Danske Bank A/S and ABN Amro Bank N.V. act as the lead managers for the issue of the Notes.
