4	Assumptions

4.1	For the purposes of this opinion we have assumed (without making any independent investigation):

	(a)	the genuineness of all signatures (including but not limited to digital signatures), the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, conformed or photostatic copies and the authenticity of the originals of such latter documents;

	(b)	that, for any digital signature, such signature was in fact affixed to the relevant document by the individual authorised to do so;

	(c)	that, other than under the laws of Sweden, each of the Corporate Documents, constitute valid and legally binding obligations on the parties thereto and are enforceable by the parties thereto under all applicable laws and in all applicable jurisdictions and, insofar as any such obligation is to be performed in any jurisdiction other than Sweden, its performance will not be illegal or ineffective by virtue of the laws of that jurisdiction;

	(d)	that the consent, permit or license of any third person, authority or governmental agency outside Sweden which is required in relation to the execution and delivery of the Corporate Documents and the performance and observation of the terms thereof by the parties and the creation of the security pursuant to the Corporate Documents, has been obtained at the date of this opinion;

5	Legal Opinions

5.1	Based upon the foregoing, and subject to the qualifications set out below and any matters not disclosed to us in writing, it is our opinion that under Swedish law:

	(a)	The Company is a public limited liability company (Sw. publikt aktiebolag) registered and validly existing under the laws of Sweden;

	(b)	The Shares will be validly issued, fully paid for and non-assessable when (i) the Company has taken all necessary actions to issue the Shares in accordance with the terms of the 2023 Incentive Plan, the Warrants or the 2026 Incentive Plan, as applicable, (ii) the Shares have been properly subscribed for, (iii) the Shares have been properly allotted by the board of directors of the Company, (iv) the Company has received in full all amounts payable for such Shares, and (v) the Shares have been registered with the SCRO.

6	Qualifications

	The qualifications to which this opinion is subject are as follows:

6.1	no opinion is expressed as to the enforceability in Swedish courts of any judgement rendered in any jurisdiction outside Sweden. The availability in Swedish courts of equitable remedies, such as injunction and specific performance, is restricted under the laws of Sweden;

6.2	any legal proceedings in the courts of Sweden will be conducted in Swedish and a court or enforcement authority in Sweden may require, as a further condition for admissibility and/or enforceability, the translation into Swedish of any relevant document and assistance from Swedish authorities in the service of process in connection with foreign proceedings might require the observance of certain procedural and other regulations;

6.3	the Corporate Documents and this opinion are expressed in the English language whilst addressing and explaining institutions and concepts of the laws of Sweden; and such institutions and concepts may be reflected in or described by the English language only imperfectly; and we express no opinion on how the courts of Sweden would construe contractual language expressed in English where the contract would be subject to the laws of Sweden. However, we believe that such courts would pay attention to the meaning and import in the laws of any pertinent jurisdiction in which the English language is normally or habitually employed of the expressions used in construing what the parties intended to put in writing for the purposes of the laws of Sweden;

6.4	pursuant to judicial precedent and general principles of Swedish company law, a Swedish limited liability company may not validly assume contractual liability (whether in the form of indemnity obligations or otherwise) in relation to a shareholder (or any person who might be equated with a shareholder) where such liability pertains to an acquisition or subscription of shares or other financial instruments issued by the company;

6.5	it is in no event possible under Swedish law to enforce obligations or have recourse to remedies against a non-performing obligor under an agreement, without requesting the assistance of the Enforcement Service Authority (Sw. Kronofogdemyndigheten) and/or the courts of Sweden, and it will in all such cases be necessary to file the relevant documentation in order to enforce obligations or have recourse to remedies;

6.6	the enforcement of the rights of a party under an agreement may be limited by general and special time-bar provisions or by failure to pursue the claim timely or in a correct manner (laches);

6.7	we express or imply no opinion of any laws other than the laws of Sweden as currently applied by the Swedish courts and regulatory agencies, and have made no investigation of any other laws which may be relevant to the Corporate Documents or the opinion given by us; in particular, we express no opinion on European Community law as it affects any jurisdiction other than Sweden; and

6.8	this opinion is strictly limited to the matters stated herein and is not to be read as extending by implication to any other matters in connection with the Corporate Documents.

7	Benefit, Reliance and Governing Law

7.1	This opinion letter is for your benefit in connection with the Registration Statement and may be relied upon by you and by persons entitled to rely upon it pursuant to the applicable provisions of the Act.

7.2	We are not responsible for, and have not provided, any advice on the legal effect of the assumptions, limitation and qualifications set out in this opinion. Persons entitled to rely on this opinion should obtain their own legal advice on the effect, completeness and extent of application of those assumptions, limitations and qualifications.

7.3	This opinion is rendered in Sweden and shall be governed by and construed in accordance with the substantive laws of Sweden in force as at the date of this opinion.

We hereby consent to the filing of this opinion letter as Exhibit 5.1 to the Registration Statement and the references to this firm in the sections of the Registration Statement entitled “Legal Matters.” In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Act or the rules and regulations of the Commission thereunder.
