BRASTER S.A.
BRASTER Spolka Akcyjna (BRASTER S.A.) is a Polish joint-stock company registered in the National Court Register (KRS) under number 0000405201, with NIP 5213496648 and REGON 141530941. It was incorporated on 13 December 2011 and is registered at ul. Cichy Ogrod 7, Szeligi, 05-850 Ozarow Mazowiecki, Poland. The company’s KRS entry currently shows an active registration.
BRASTER S.A. develops and manufactures a medical device, marketed as BRASTER PRO, based on proprietary liquid crystal contact thermography (Continuous Liquid Crystal Film) technology. The device produces contact thermographic images of the breast that are interpreted with automated algorithms to flag potentially abnormal areas, and it is positioned as a complementary, radiation-free tool alongside standard breast-screening methods such as mammography and ultrasound. Independent pilot research published in peer-reviewed medical literature has evaluated the device’s sensitivity and specificity across different age groups.
BRASTER S.A. was previously listed on the Warsaw Stock Exchange (Gielda Papierow Wartosciowych, GPW) Main Market under ticker BRA/BRAR and ISIN PLBRSTR00014. The Polish Financial Supervision Authority (Komisja Nadzoru Finansowego, KNF) issued a decision, dated 19 September 2025, imposing an administrative penalty on the company for grossly inadequate periodic disclosures covering its 2018-2023 annual reports and complete non-publication of its interim report for the first half of 2024. Acting on this decision, the GPW Management Board (Resolution No. 1470/2025 of 24 November 2025) excluded BRASTER S.A. shares from trading on the Main Market, effective 29 November 2025.
The company has a history of financial and restructuring difficulty. An arrangement (uklad) reached in accelerated arrangement proceedings was approved by the Warsaw court on 12 October 2022, after which the "w restrukturyzacji" designation was removed from the company’s KRS entry in January 2023. That arrangement was subsequently annulled by a Warsaw court ruling on 18 April 2024, and BRASTER S.A.’s appeal against the annulment was rejected on 15 January 2025.

Shareholders
Shareholders of BRASTER S.A.
BRASTER S.A. (KRS 0000405201, NIP 5213496648, REGON 141530941) is a spolka akcyjna. The National Court Register does not record shareholders for that legal form; in Poland a registered shareholder list exists only for a spolka z ograniczona odpowiedzialnoscia. Ownership disclosure therefore rested entirely on notifications of significant holdings under the Act on Public Offering, published as company current reports while the shares traded on the Warsaw Stock Exchange Main Market.
In the 2021 financial year no shareholder held 5% or more of the votes. Notifications received on 14 March 2022 (5.08%) and 18 March 2022 (5.004%) recorded two holdings, each held by members of the company’s governing bodies, crossing it. A notification received on 16 October 2023 recorded Elzbieta Pielak holding 2,006,000 shares, 6.83% of the share capital and votes, from nil. The company’s list for the general meeting of 30 July 2024 records that holding, then 6.82% of total votes, as the only one above 5%.
Notified holdings cover only positions above the 5% threshold, not the full shareholder base. The shares were excluded from trading on the GPW Main Market with effect from 29 November 2025; notification reporting ceased and no disclosure later than 30 July 2024 exists.
Data availability
Historical. Only holdings above the statutory 5% threshold were ever published, and the most recent such disclosure is dated 30 July 2024. The company had 29,383,298 shares in issue on a share capital of PLN 2,938,329.80; the votes represented at the meeting of 30 July 2024 totalled 5,052,768, about 17% of the shares in issue, so the majority of the register of shareholders has never been disclosed.
The Centralny Rejestr Beneficjentow Rzeczywistych (CRBR) search service was queried on 30 September 2026 by NIP 5213496648 and by KRS 0000405201 for the whole period since the register opened on 13 October 2019. It returned an empty result set, but a control query for an unrelated registered company also returned an empty result set, so the query is treated as inconclusive. No beneficial owner is stated here, and this is not evidence that none is registered.

Directors and officers of BRASTER S.A.
BRASTER S.A.’s registry data lists two active officers. Dariusz Karolak holds the role of President of the Management Board (Prezes Zarzadu); external company and press sources confirm he was appointed to this position on 6 March 2020 and is a founding shareholder of the company. Dominika Grochowska is recorded as Chief Accountant. No resigned or former officers are included in the reviewed dataset, and no resignation or termination dates are recorded for either individual, so both are treated as active.
As a Polish spolka akcyjna, BRASTER S.A. is also required to maintain a supervisory board (rada nadzorcza) alongside its management board. Company announcements referenced changes to the supervisory board’s membership in 2023 and 2025, but the individual members and their appointment dates could not be independently verified from a primary source within this review and are therefore not included here.
Nationality is not disclosed in the reviewed KRS-sourced data for either officer; only a Poland correspondence country is recorded, and this should not be read as evidence of nationality or residence.
Data availability
Officer information in this profile is sourced from the Polish National Court Register (KRS) dataset and reflects current management board appointments only. Historical or resigned officer records and the current supervisory board composition are not confirmed in this dataset and are treated as partial/not disclosed.
Data-provider feed — rows as supplied to Zavia for National Court Register (KRS), including entries the profile above does not cover. These rows are not a verbatim copy of the register: they have been found to duplicate the same person under different spellings and to keep a status of Active after an appointment ended. Where they disagree with the profile above, the profile is the checked version.
Group Structure
Group structure of BRASTER S.A.
BRASTER S.A. (KRS 0000405201) is an independent entity. Its management report for the 2021 financial year, dated 2 May 2022, states that the company does not form a capital group for accounting purposes, holds no shares in any other company, is not a partner in any partnership, and that no parent entity and no entity exercising control over it exists. The same report and the register record no branches, and no consolidated financial statement has ever been filed. The plan the company described at that date, to expand into renewables, energy storage and e-mobility through companies intended to become subsidiaries, was conditional on performance of the court arrangement, and no such holding is evidenced in the register.
The company was in accelerated arrangement proceedings from 30 April 2020 until 12 October 2022, and the arrangement was subsequently annulled. As at the register state of 20 November 2025 there is no entry recording bankruptcy, liquidation or deletion, and the company remains registered; an appointed arrangement supervisor is still recorded in Division 6 alongside the company’s own bodies.
Recent structural changes
- 12 January 2023 — KRS entry no. 61 recorded the closure of the accelerated arrangement proceedings (case XVIII GR 15/20) on 12 October 2022 by approval of the arrangement, and removed the designation “w restrukturyzacji” from the registered name, which had been added by entry no. 45 on 16 September 2020. Source: KRS full extract, Divisions 1 and 6.
- 18 April 2024 — the Sad Rejonowy dla m.st. Warszawy, XVIII Commercial Division, annulled the arrangement concluded in those proceedings; the company’s appeal was dismissed by the Sad Okregowy w Warszawie, XXIII Commercial Division, on 15 January 2025. Source: BRASTER S.A. current report 2/2025 of 12 February 2025. This change is not reflected in Division 6 of the register as at 20 November 2025.
- 29 November 2025 — BRASTER S.A. shares (ISIN PLBRSTR00014) were excluded from trading on the GPW Main Market under Resolution No. 1470/2025 of the GPW Management Board of 24 November 2025, giving effect to the decision of the Komisja Nadzoru Finansowego of 19 September 2025. Source: GPW; KNF.
Data availability
Partial. No corporate ownership relationship, inbound or outbound, is evidenced by any filing, so no relationships table is published. The related parties named in the 2021 management report are companies connected to BRASTER only through individuals, not through any shareholding held by or in BRASTER, and absence of a recorded relationship is not evidence that none exists.
The register evidences the current absence of branches and of any group filing, and the company’s own last full statement on group membership is dated 2 May 2022. No annual financial statement for a period after 2021, and no management report for a period after 2022, is recorded in the register, so the position since then is not evidenced by a filing.
