Shareholders
Shareholders of Instal Krakow S.A.
Instal Krakow S.A. is a Warsaw Stock Exchange-listed issuer that discloses its shareholding structure through statutory notifications of shareholders holding at least 5% of votes at its General Meetings. According to the list of shareholders holding at least 5% of votes at the Annual General Meeting held on 19 June 2026 (published 22 June 2026), Piotr Juszczyk held 3,509,049 votes, representing 30.08% of the company’s total voting rights; Juroszek Holding Sp. z o.o. held 1,971,509 votes, representing 16.90% of total voting rights; and funds managed by Esaliens TFI S.A. held a combined 1,273,456 votes, representing 10.92% of total voting rights, including 686,124 votes (5.88%) attributed to the Esaliens Parasol FIO Subfundusz Akcji sub-fund. Because Polish listed issuers disclose only holdings crossing statutory notification thresholds (5% and its multiples), this overview reflects major, reportable shareholders as of the meeting date and does not represent the complete shareholder base. Combined, these disclosed holders represented roughly 64% of total voting rights, with the remainder held by smaller institutional and other investors below the notification threshold.
Ultimate beneficial ownership
No single shareholder holds a majority of Instal Krakow S.A. Piotr Juszczyk, the company’s President of the Management Board and CEO, is the largest disclosed direct holder with 30.08% of total voting rights as of 19 June 2026, a holding that exceeds the 25% voting-rights threshold generally applied under Poland’s beneficial-ownership disclosure rules. Separately, Juroszek Holding Sp. z o.o., which company registry data shows is wholly (100%) owned by Zbigniew Juroszek, held 16.90% of total voting rights as of the same date; on that ownership chain, Zbigniew Juroszek’s calculated effective indirect voting interest in Instal Krakow S.A. is approximately 16.90% (100% x 16.90%), below the 25% threshold. This overview is based on share-register and voting-rights notifications rather than a direct Central Register of Beneficial Owners (CRBR) filing.
Data availability
Shareholder disclosure for this GPW Main Market-listed company is major-shareholders-only: only holdings crossing the 5% voting-rights notification threshold are published. Zavia’s own underlying shareholder record for this company (sourced via the KRS/CRBR data provider) does not currently list any filed shareholders for this entity, so this section instead relies on the company’s statutory 5%-threshold meeting-attendance disclosures and secondary market-data aggregation, dated between 21 November 2025 and 22 June 2026.
