After reports of possible new searches in the case of the pharmaceutical company “FARMACEL,” businessman Serhiy Dyadechko has again come into focus. An analysis of state and international registries showed that the former co-owner of Rodovid Bank remains a participant in Ukrainian companies alongside sanctioned Denis Horbunenko and Dmitry Yehorenko, who was convicted in the Rodovid Bank case; he controls businesses in the United Kingdom, Cyprus, and offshore jurisdictions, and companies linked to him appear in criminal proceedings concerning Donbasenergo, the Arsenal plant, LLC NIKO and other high-profile cases. The StopKor team traced what Dyadechko’s business network actually looks like and what connections he has.
The story around the Ukrainian pharmaceutical manufacturer FARMACEL has taken a new turn. According to information published by StopKor, new searches and the issuing of suspicions may take place in the case soon, and among the potential beneficiaries of the procedural actions they name businessman Serhiy Dyadechko.
This new escalation of the conflict once again drew attention to Dyadechko, whose name has featured for many years in high-profile banking, financial, and corporate scandals.
From tax inspector to banker and businessman
Serhiy Dyadechko’s career began far from big business. In 1996 he graduated from the Donetsk Polytechnic Institute with a degree in Computer Engineering and Informatics, and three years later he obtained a second higher education in Accounting and Auditing. His first job was with the tax service. In 1996–2000 Dyadechko worked at the Donetsk tax inspectorate, where he rose to the position of chief inspector of the Tax Investigations Department of the regional State Tax Administration.
After leaving public service he moved to the private sector, trading in metal, coal, and mining equipment. That period became the starting point for his subsequent career in the financial sector.
In 2004 Dyadechko, together with a group of business partners including Denis Horbunenko, Dmitry Yehorenko and the Bubka brothers, became a co-owner of Donetsk Perkombank. The financial institution was later renamed Rodovid Bank, where he held executive positions and was mentioned as one of the co-owners and vice presidents.
The next step was founding his own bank. In 2007 Dyadechko established the bank Soyuz, becoming its sole owner.
In 2016 the National Bank of Ukraine decided to liquidate the financial institution. The businessman appealed the decision in court and achieved partial satisfaction of his claims.
Alongside his banking activities Dyadechko actively invested in sports. He was president and owner of the basketball club Donetsk,
founded the international fund Dyadechko Sport Fund, and after moving to Monaco in 2012 became one of the executives of the basketball club Monaco. And in 2022 he sold AS Mona46, 4% to Russian businessman Oleksiy Fedorichev, while retaining the position of vice president of the club for sports operations.
At the same time Dyadechko continues to present himself as a patron and philanthropist who supports the development of professional basketball and sports initiatives.
Sanctioned partners, offshore entities and criminal proceedings: a business profile of Serhiy Dyadechko
Despite relocating to Monaco, Serhiy Dyadechko did not sever ties with Ukrainian business. Data from the Unified State Register indicate that he remains a co-owner of at least two companies — LLC UKRBUSINESSRESOURCE and LLC RB CAPITAL-GROUP. What draws attention is not so much their existence as the circle of people with whom the businessman continues to do business.
In both companies Dyadechko’s partners are former co-owners and executives of Rodovid Bank, Denis Horbunenko and Dmitry Yehorenko. The first is currently under sanctions by the National Security and Defense Council and the United Kingdom, Ukrainian media report. British authorities have stated that Horbunenko may have facilitated money laundering and acted in the interests of Dmytro Firtash during his work at Rodovid Bank.
Equally notable is Dmitry Yehorenko. The former chairman of Rodovid Bank has been declared internationally wanted by Interpol.
The proceedings concerned crimes under Part 5 of Article 191 and Part 1 of Article 366 of the Criminal Code of Ukraine. Open sources also reported that the investigation linked him to the misappropriation of 18,45 million UAH from Rodovid Bank, in which former MP Oleksandr Shepelev was implicated. On 9 April, the High Anti-Corruption Court sentenced Yehorenko in absentia to ten years in prison with confiscation of all property of the former chairman of the board of JSC Rodovid Bank, but exempted him from serving the sentence due to statute-of-limitations expiration, LIGA.net reported.
Another co-founder of LLC RB CAPITAL-GROUP is Serhiy Bubka.
According to Russian state registries, he remains a co-owner of the companies Firma Montblanc and Sporting Club of Serhiy Bubka, registered in occupied Donetsk.
According to their tax reports, in 2025 alone these enterprises paid over 16 million rubles to the budget of the Russian Federation.
Among companies linked to Serhiy Dyadechko special attention falls on LLC NIKO — a pharmaceutical manufacturer for which he is listed as the ultimate beneficiary in state registers. According to open sources, the enterprise is undergoing bankruptcy proceedings and in 2024 lost its license to import medicinal products.
At the same time, in recent years the company has repeatedly appeared in criminal proceedings. In cases No. 761/12254/19 and No. 761/6517/19 law enforcement investigated possible tax evasion by officials of LLC NIKO on an especially large scale (Part 3 of Article 212 of the Criminal Code of Ukraine). According to the investigation, the enterprise imported products through the British company Devolia Estate LLP at inflated prices, and the price difference was transferred to the accounts of LLC Krastus under assignment-of-claim agreements.
Another proceeding (No. 760/30574/18) concerned possible evasion of unified social contribution payments. According to investigators, during 2017 — the first quarter of 2018 officials of the enterprise did not pay over 1,9 million UAH in unified social contributions despite sufficient funds on the company’s bank accounts.
In 2023 the name LLC NIKO again appeared in criminal case materials, this time after a high-profile incident at a Dnipro hospital. According to case No. 204/12098/23, after procedures using intravenous anesthesia nine patients, including children, developed severe complications such as shock and multiple organ failure. In the investigation, authorities examined a possible link between these outcomes and the use of the drug Emeton produced by LLC NIKO.
Among assets connected to Serhiy Dyadechko are not only banks and financial companies. State registries also list him as a co-owner of the agricultural cooperative named after O. Kobylianska in Chernivtsi region, whose main activity is growing cereals, legumes and oilseeds. Attention is drawn not only to the composition of the founders but to the cooperative’s land bank. State registries show that the cooperative owns 132 land plots and two real estate objects in Chernivtsi region.
Co-owners of the cooperative along with Dyadechko include Olena Pavlina — a former assistant to MPs from the Party of Regions who in 2010 was elected to the Kyiv regional council from that political force,
and also Oleksandr Votintsev — a former assistant to a Member of Parliament from the Party of Regions.
Another asset in which Dyadechko remains a participant is PJSC ZNVKIF “Ukrainian Project Investments” — a corporate investment fund that has been repeatedly mentioned in criminal case materials.
In particular, in case No. 752/5804/23 the investigation is probing the possible misappropriation of 532 million UAH from PJSC Donbasenergo, 25% of whose shares are state-owned. According to the case materials, the funds were moved under the guise of repaying a loan under an agreement of 2013 with PJSC ZNVKIF “Ukrainian Project Investments”. The claim rights were repeatedly transferred between related structures through factoring agreements and securities transactions, after which the money, according to investigators, ended up in individuals’ accounts.
In addition, the fund’s securities are mentioned in two other criminal cases. In case No. 405/7891/15-k law enforcement investigated possible financing of the terrorist organization “DPR”. According to the investigation, officials of LLC Charnokit used, among other things, securities issued by PJSC ZNVKIF “Ukrainian Project Investments” in schemes the proceeds of which may have been directed to financially support illegal armed groups. The investigation also alleged that certain companies made payments to the so-called “Ministry of Revenues and Duties of the DPR.”
In another proceeding — No. 405/6829/15-k — investigators examined LLC Charnokit for possible evasion of over 4,1 million UAH in taxes. According to law enforcement, the scheme included the use of companies with signs of fictitiousness, arranging the export of crushed stone to Russia, unjustified formation of tax credit and understating payments for subsoil use. Materials of this case also mention securities transactions linked to the Ukrainian Project Investments fund.
Another asset for which Serhiy Dyadechko is listed as the ultimate beneficiary in state registers is LLC ISV-INVEST — a construction company whose founders include the international company ADELIS INC., registered in the Seychelles. As media write, this company is included in a list of offshore firms.
The company’s name also repeatedly appeared in criminal case materials related to the divestment of state property. In proceeding No. 42017000000001215 investigators are probing possible complicity in the embezzlement of property on an especially large scale and abuse of power. According to the investigation, officials of the Corporation NVO Arsenal, LLC SKAYNET Ltd and LLC NOVA TOR concluded a series of transactions that resulted in state real estate objects that were not subject to privatization being alienated to private companies. Among the acquirers of the property investigators name LLC ISV-INVEST, LLC OST ENERGY GROUP, LLC MIRRA DEVELOPMENT and a number of other enterprises.
Another proceeding — No. 62019100000001928 — concerns the possible unlawful alienation of the property complex of SE Plant Arsenal in the Pecherskyi district of Kyiv. According to investigators, the complex with an area of almost 5 thousand sq. m was removed from state ownership at an undervalued price. One of its objects — building No. 47 (the cooling tower) — as a result of these operations passed into the ownership of LLC ISV-INVEST.
In addition, the company appears in criminal proceeding No. 22015101110000029 along with LLC PATRIOT HOLDING, PJSC ZNVKIF “Ukrainian Project Investments” and LLC INVESTBUDKAPITAL, which indicates an intersection of these structures in a single investigation. At the center of these episodes is also the Corporation NVO Arsenal. Investigators consider its officials participants in the scheme to alienate state property. Separately, the military prosecutor’s office investigated another criminal proceeding (No. 42017000000001891), which concerned possible abuse of office by officials of SE Plant Arsenal during fulfillment of a state defense order. According to the case materials, the Corporation NVO Arsenal received a contract to perform R&D work “Rokach A” to modernize the Shilka anti-aircraft system, but transferred a significant portion of the work to private structures including LLC SKAYNET LTD and PJSC Mirrad. Law enforcement believes such actions caused losses to the state of about 23 million UAH.
Attention is also drawn to the composition of participants of the Corporation NVO Arsenal. In 2016–2017 years among the co-founders was the company LLC ALTERNATIVA PLUS, whose owner in various years was Russian Federation citizen Vagif Aliyev, and until April 2022 he was a beneficiary of the Corporation NVO Arsenal.
Some business assets linked to Serhiy Dyadechko are registered not only to him personally but to his wife, Olha Dyadechko. Several companies overlap with known business partners of the entrepreneur, offshore structures and enterprises that have appeared in criminal cases. Thus, Olha Dyadechko is a co-owner of LLC ISV-INVEST — a company whose ultimate beneficiary is also listed as Serhiy Dyadechko. The enterprise is registered in Donetsk, and among its participants, in addition to Olha Dyadechko, are Serhiy Nuzbrokh and Oksana Mykhailychenko. According to open sources, Nuzbrokh is included in the Myrotvorets database and is wanted for Part 1 of Article 263 of the Criminal Code of Ukraine (illegal handling of weapons).
The asset list also includes LLC PATRIOT HOLDING, which was already mentioned among companies that featured in several criminal proceedings. In addition, Olha Dyadechko is a participant in LLC KD ENERGY 2. State registries show the enterprise is part of the group of companies of Denis Horbunenko — a long-time business partner of Serhiy Dyadechko who is under sanctions by the National Security and Defense Council of Ukraine and the United Kingdom.
Another company — LLC PTK VELES — is again registered to the offshore company ADELIS INC., registered in the Seychelles.
According to archival data, in 2011–2013 the enterprise carried out foreign trade operations with the Russian Federation.
From London to offshore jurisdictions: Serhiy Dyadechko’s international companies
State and international corporate registries contain information about Serhiy Dyadechko’s participation in a number of foreign companies. The majority of such companies are registered in the United Kingdom. In particular, Serhiy Dyadechko is still listed as director of TOOLEY CONTRACTORS LIMITED and TOOLEY PROPERTY COMPANY LIMITED.
He was appointed to those positions on 29 February 2008. Until May 2023 he was also a person of significant control (PSC) in TOOLEY PROPERTY COMPANY LIMITED, after which control over the company passed to Yevhen Dyadechko. According to the British registry, the latter is registered in Monaco at 23 Boulevard de Belgique, L’Oiseau Bleu — the same address that Serhiy Dyadechko lists in his corporate documents.
Another British company is ASHBURG VENTURES CORP. LIMITED. Since July 2022 Dyadechko has been its director and simultaneously the person controlling over 75% of the company’s shares. Company documents also list his country of residence as Monaco.
Corporate links are also traced in Cyprus. In the local registry Serhiy Dyadechko is listed as director of KD ENERGY HOLDING LIMITED, KD 2 ENERGY HOLDING LIMITED and VOIDANCE PROJECT LTD.
Offshore structures are of particular interest. In the ICIJ Offshore Leaks international database, compiled from the Panama Papers documents, Serhiy Dyadechko is listed as a shareholder of five companies registered in the British Virgin Islands: Mayfield Capital Trading Limited, Winterbourne Assets Limited, Holywell Estate Limited, Fleetside Services Limited and Hullbrook Limited.
In addition, in December 2007 a company DYADIMMO S.A. was registered in Luxembourg, which is also associated with Serhiy Dyadechko.
Thus, open international registries indicate that Serhiy Dyadechko’s corporate links span several foreign jurisdictions — from the United Kingdom and Cyprus to Luxembourg and the British Virgin Islands.
From the bankruptcy of NIKO to ties with the Russian Federation: what else is associated with Serhiy Dyadechko
Serhiy Dyadechko’s name has for many years regularly appeared in investigative journalism and Ukrainian media publications. Recently media attention focused on the situation around the pharmaceutical manufacturer FARMACEL. UNIAN reported searches at the enterprise and the company’s statements about alleged pressure in the bankruptcy procedure of LLC NIKO — a company previously led by Serhiy Dyadechko. OBOZ.UA, in turn, wrote that the bankruptcy proceedings for NIKO were opened in spring 2026, and one of the creditors was LLC Skhid Finance, whose banking license was later revoked by the National Bank of Ukraine.
The outlet characterized the situation as a conflict that went beyond an ordinary commercial dispute.
Earlier, several media outlets published materials about NIKO’s activities. For example, Gordon.ua reported that the enterprise, whose owner was named as Tamara Dyadechko — Serhiy Dyadechko’s mother — and related companies Donbasspharm and Nikafarm allegedly continued producing medicines in Makiivka after the occupation, were registered with the so-called DPR authorities and sold products in Ukraine. In connection with this, MP Yuriy Bereza appealed to the SBU and the Prosecutor General’s Office to check possible financing of terrorism.
The media space has also repeatedly mentioned episodes from Serhiy Dyadechko’s own history. LB.ua reported that in 2012 a banker's car was shot at in Sofiyivska Borshchahivka near Kyiv. Dyadechko himself, his driver and a passerby were wounded in the attack, and law enforcement opened a criminal case for attempted murder. Two years later Dzerkalo Tyzhnia published a statement by Dyadechko in which he claimed that former MP Oleksandr Shepelev allegedly prepared a renewed attempt due to a fabricated criminal case in Russia. These claims remained the businessman’s personal position.
Many journalistic materials have focused on the history of Rodovid Bank. Over the years media, citing investigation materials and NABU, reported on the possible embezzlement of 35 billion UAH from the bank through loans to related structures. Serhiy Dyadechko publicly denied any involvement in illegal schemes.
Journalists have also scrutinized his international ties. Football24 reported that in early 2022 Dyadechko sold nearly half of the shares of basketball club Monaco to Russian businessman Oleksiy Fedorichev. Despite the change in ownership structure, Dyadechko remained vice president of the club for basketball operations. The outlet also linked the club’s subsequent financial problems to that deal.
To clarify the situation, the StopKor team sent inquiries regarding the activities of Serhiy Dyadechko and companies associated with him. In particular, a request was sent to the National Bank of Ukraine about the history of the banks associated with Serhiy Dyadechko, the circumstances of Rodovid Bank’s operations and the bank Soyuz, as well as information about regulatory decisions and measures concerning these institutions.
An inquiry was sent to the Security Service of Ukraine regarding possible checks and information that may relate to the activities of the persons and companies mentioned in the material, including possible national security risks.
A request was sent to the National Anti-Corruption Bureau of Ukraine regarding possible criminal proceedings and investigations involving Serhiy Dyadechko or companies linked to him.
The StopKor editorial team is currently awaiting responses from state authorities.
Recall that the StopKor team wrote about Pavlo Zhuryl’s gambling empire and about how sports clubs, a charitable fund, fuel business and state tenders ended up in the orbit of people from Kostyantyn Havrylenko’s circle
