Hunterbrook: CSG Paid ~€18M to Unwind a Stake Sale That Generated €410K, With the Counterparty Linked to the Intermediary Behind Nearly a Fifth of Its Entire Backlog

The Vývoj Martin reacquisition is the financial anomaly that anchors the report: CSG's prospectus records a €24.4 million payment to regain a Slovak subsidiary stake that had generated only €410,000 when sold in 2021, implying a net outflow of roughly €17.9 million – with no counterparty named and the IFRS 3 fair-value disclosure listing CSG's pre-existing shares as zero despite prior filings valuing them at roughly €18 million. The Singapore counterparty, RDBSG, lists human resource consultancy as its business and a coworking space as its address; its sole proprietor also owned an entity previously named Republikorp Project Management Services. That name connects to Norman Joesoef's Republikorp, which Hunterbrook identifies as the central conduit for CSG's Indonesia business – a $300 million armored vehicle deal and a $2.5 billion air-defense package announced weeks after the IPO, together representing nearly a fifth of CSG's €15 billion backlog. CSG's own subsidiary explicitly named Indonesia as the buyer of a matching air-defense system in 2022, and CSG's annual reports identified Indonesia as the only material Southeast Asian customer. Nobody at CSG, Republikorp, or Irwan Bin Omar responded to repeated requests for comment.

Thesis

Hunterbrook alleges CSG paid roughly €18 million in cash to reverse a Slovak subsidiary stake sale that originally generated only €410,000, with the counterparty appearing linked to Republikorp — the intermediary the report identifies as the conduit for nearly a fifth of CSG's total backlog.

• The Buried Buyback: CSG's 728-page IPO prospectus records a €24.4 million acquisition of Vývoj Martin on page 374, with no counterparty named. Slovak statutory filings show the entity being bought back from was RDBSG, a Singapore company that had paid only €410,000 of an agreed €5.85 million purchase price in 2021 before the deal was canceled — yet CSG's prospectus records a net cash outflow of approximately €17.9 million on the reacquisition.
• Mystery Counterparty: RDBSG is registered in Singapore as providing "human resource consultancy services," has no website, and lists an address matching a coworking space. Its sole proprietor is Irwan Bin Omar, who also owned an entity called Republikorp Project Management Services Pte. Ltd., later renamed Research and Development Innovations.
• Accounting Anomaly: CSG's IFRS 3 disclosure lists the value of its pre-existing shares in Vývoj Martin as zero on the "Investment value as of the control acquisition" line, even though prior CSG disclosures indicated those shares were worth roughly €18 million as of 2023. JP Krahel, chair of Loyola University Maryland's accounting department, told Hunterbrook that IFRS 3 requires disclosure of the fair market value of pre-existing ownership at the moment control is acquired, making the zero entry inconsistent with standard treatment — implying either an unexplained impairment or a presentation of the transaction as a fresh acquisition.
• "Southeast Asia" Means Indonesia: CSG announced a $300 million armored vehicle deal thirteen days after its IPO and a $2.5 billion air-defense package two months later, both to unnamed customers in "Southeast Asia." CSG's own subsidiary Excalibur International explicitly named Indonesia as the buyer of a medium-range air-defense system in 2022 that Hunterbrook argues matches the system described in the April announcement. CSG's 2023 and 2024 annual reports identified Indonesia as the only Southeast Asian country material enough to name specifically.
• Republikorp as Central Conduit: Virtually all of CSG's Indonesia business appears to flow through Republikorp, founded by Norman Joesoef. Deals documented in the report include: a 122-rocket-launcher contract between Excalibur Army and Republikorp; Indonesian press reports linking Republikorp to Fiocchi Munizioni on ammunition production; and an alleged 2023 Indonesian foreign ministry document, posted to a Facebook group for military enthusiasts, summarizing strategic agreements between Republikorp and Excalibur International facilitated by the Indonesian government.
• The Joesoef Network: Norman Joesoef founded Republikorp in 2013 after studying in Prague, reportedly inspired by a colleague working in a European defense conglomerate. He appears, based on social media evidence cited by Hunterbrook, to be the son of Harsha Edwana Joesoef — founder of Indonesian logistics group RPX and Indonesia's ambassador to Slovakia from 2009 to at least 2012. Republikorp's listed address matches RPX's Jakarta headquarters. The familial and diplomatic ties are circumstantial but place the intermediary directly in the Czech-Slovak-Indonesian orbit surrounding CSG.
• Backlog Concentration Risk: The $300 million and $2.5 billion deals together represent nearly a fifth of CSG's €15 billion backlog. More than half the backlog is ammunition-related, meaning the Indonesia-linked contracts could amount to nearly half of CSG's non-ammunition backlog — concentrated in one country and, the report alleges, one intermediary.
• Fighter Jet Controversy: In 2023, Excalibur International brokered a $792 million transfer of 12 used Qatari fighter jets to Indonesia — implying $66 million per jet for aircraft Qatar had once offered for free. Indonesian outlet Ceri reported Republikorp served as intermediary, citing defense ministry officials. A separate report alleged a 7% kickback worth approximately $55.4 million to then-defense minister Prabowo Subianto, including a $20 million upfront payment. Prabowo's campaign denied the allegation as fake news. Indonesia later canceled the jet deal citing budget limitations. Hunterbrook states it could not independently corroborate the kickback claims or related investigative referrals.

Notable Details

• The reacquisition implies a potential return of more than 4,000% on RDBSG's €410,000 outlay — if the roughly €18 million cash outflow went to the same party that originally paid only the deposit.
• When a Hunterbrook reporter called CSG's spokesperson after emails went unanswered, the spokesperson said "Please communicate in written form" and, when pressed, hung up. Nobody at CSG, Republikorp, Norman Joesoef, or Irwan Bin Omar responded to repeated requests for comment.
• A regional defense outlet reported military enthusiasts spotted a tactical ballistic missile system mounted on 8×8 Tatra trucks at an Indonesian army base in Borneo in 2025 — consistent with Hunterbrook's claim that deliveries under the 2022 air-defense agreement have already begun.
• Indonesian Antara News reported in 2018 that CSG CEO Michal Strnad pledged to invest $100 million in an Indonesian industrial park to be headed by Norman Joesoef as CEO of "Czechoslovak Group Indonesia." References to that entity later disappeared; Hunterbrook argues Republikorp subsequently emerged as the apparent independent intermediary in its place.
• Beyond Indonesia, the only other Southeast Asian deal Hunterbrook identified at remotely comparable scale was a 2022–2023 subcontract for 10 armored vehicles supplied to the Philippines through Elbit Systems — making CSG's "Southeast Asia" framing appear to rest almost entirely on one market.

"The bottom line is, according to the accounting, CSG seems to have spent about 18 million euros as part of a deal to buy back shares it had sold for just 410,000 euros three years prior."
