Citigroup Withdraws as Major Shareholder in Boss Energy Following Securities Lending Agreement Adjustments

Boss Energy’s Position in Australia’s Uranium Industry

Boss Energy Ltd is a publicly listed Australian company focused on uranium exploration and development, contributing to the global nuclear fuel supply chain. The company’s uranium projects align with Australia’s expanding role as a supplier of nuclear fuel to international markets. As global demand for uranium rises amid renewed interest in nuclear energy as a low-carbon power source, Boss Energy has attracted investor attention for its exposure to this commodity cycle.

Listed on the Australian Securities Exchange, Boss Energy is a significant player in the local mining sector and offers investors access to uranium price movements and project development outcomes. Its focus on uranium exploration positions it centrally within Australia’s efforts to meet growing global nuclear fuel needs, especially given heightened energy security and climate change considerations driving nuclear power adoption worldwide.

Citigroup’s Shareholding Reductions Across Multiple Entities

The reduction in substantial shareholding involved several Citigroup entities. Citibank N.A. Sydney Branch decreased its relevant interest by 386,671 fully paid ordinary shares, while Citigroup Global Markets Inc reduced its holdings by 700,000 shares. Additionally, Citigroup Global Markets Limited lowered its relevant interest by 82,533 shares. These coordinated decreases indicate a systematic unwinding of Citigroup’s securities positions in Boss Energy across its global legal entities.

Conversely, Citigroup Global Markets Australia Pty Limited increased its relevant interest by 86,412 shares through ordinary market transactions. The net effect of these adjustments resulted in Citigroup no longer qualifying as a substantial shareholder in Boss Energy. This rebalancing reflects strategic portfolio changes and modifications to the financial arrangements underpinning Citigroup’s major shareholding in the uranium company.

Impact of Securities Lending Agreements on Shareholding Changes

The shareholding shifts stemmed from changes in securities lending agreements between Citigroup entities and counterparties. Citibank N.A. Sydney Branch, Citigroup Global Markets Inc, and Citigroup Global Markets Limited all adjusted their holdings in line with obligations to return securities under standardised lending frameworks including AMSLA (Australian Master Securities Lending Agreement), GMSLA (Global Master Securities Lending Agreement), and MSLA (Master Securities Lending Agreement).

These agreements operate under industry-standard terms granting both lenders and borrowers early recall rights. Importantly, borrowers retained full voting rights over loaned securities during the lending period. The return dates for borrowed securities remain unspecified, indicating indefinite lending subject to recall provisions embedded in the master agreements.

Specific Shareholding Adjustments on 23 July 2026

On 23 July 2026, four transactions collectively led to Citigroup ceasing to be a substantial shareholder in Boss Energy. Citibank N.A. Sydney Branch, acting as an agent lender, reduced its relevant interest by 386,671 shares. Simultaneously, Citigroup Global Markets Inc lowered its holdings by 700,000 shares under securities lending return obligations.

Citigroup Global Markets Limited also decreased its relevant interest by 82,533 shares, while Citigroup Global Markets Australia Pty Limited increased its relevant interest by 86,412 shares through routine market activity. These coordinated changes resulted in a net reduction surpassing the 5% substantial shareholder threshold, prompting Citigroup’s exit from substantial shareholder status.

Securities Lending Agency Agreements and Recall Rights

Citigroup’s shareholding was supported by Securities Lending Agency Agreements (SLAA) alongside the master loan agreements. Under these arrangements, Citibank N.A. Sydney Branch acted as agent lender with authority limited to securities defined in the SLAA. The agent lender’s activities were governed by lender-imposed restrictions including designated accounts, lendable limits, acceptable collateral, and cash reinvestment policies.

Both lenders and borrowers held early recall rights under AMSLA and GMSLA terms; however, mutual agreements typically discouraged early recalls or sales during the loan term, ensuring stability. This framework allowed flexibility to address significant market or circumstance changes while maintaining predictable lending arrangements.

Regulatory Disclosure Timeline and Compliance

Citigroup’s cessation as a substantial shareholder triggered regulatory notification requirements under Section 671B of the Corporations Act. The initial substantial holding notice was provided to Boss Energy on 24 July 2026, one day after the shareholding reduction. The formal cessation notice was submitted on 27 July 2026, fulfilling disclosure obligations.

This timeline aligns with standard Australian Securities Exchange procedures for reporting substantial shareholder changes. Boss Energy received the notification and is responsible for assessing any further disclosure requirements under ASX Listing Rules or the Corporations Act.

Unchanged Associate Status in Shareholding Structure

The company confirmed no changes occurred in associate status related to the shareholding adjustments. No individuals or entities became or ceased to be associates of Citigroup entities, nor did any association nature change concerning voting interests in Boss Energy during this period. The "N/A" notation in the association section confirms these were direct changes to Citigroup’s relevant interests without involving related party restructurings.

This indicates the shareholding reduction resulted solely from securities lending position adjustments without alterations to corporate relationships or ownership patterns. Citigroup Global Markets Australia Pty Limited and related entities remained the primary parties responsible for the changes.

Global Citigroup Entities and Their Locations

The shareholding changes involved four Citigroup legal entities operating from multiple global financial centres. Citibank N.A. Sydney Branch and Citigroup Global Markets Australia Pty Limited are based at Two Park, 2 Park Street, Sydney, NSW 2000, Australia. Citigroup Global Markets Inc is located at 388 Greenwich Street, New York, NY 10013, USA. Citigroup Global Markets Limited operates from Citigroup Centre, Canary Wharf, 33 Canada Square, London, E14 5LB, UK.

This geographic diversity illustrates Citigroup’s integrated global securities and lending operations managing stakes in an Australian-listed company. The update was issued on behalf of Citigroup Global Markets Australia Pty Limited by Ji Hyun Kim, with contact number +61 2 8225 2489, designating the Australian entity as the primary regulatory liaison.

Consequences for Boss Energy’s Shareholder Composition and Outlook

Citigroup’s exit as a substantial shareholder marks a significant shift in Boss Energy’s shareholder register. Previously, Citigroup entities collectively held 5% or more of the company’s voting shares. Falling below this threshold may influence ownership dynamics, corporate governance, and future capital strategies, as major institutional investors often play crucial roles in these areas.

Investors should consider that Citigroup’s shareholding reduction likely reflects portfolio rebalancing via securities lending adjustments rather than fundamental concerns about Boss Energy’s operations. Nonetheless, the departure of a major shareholder could impact share liquidity, price behavior, and the company’s capacity to raise capital for ongoing uranium project development. Stakeholders are advised to monitor for further disclosures regarding strategic implications of this shareholder change.
