Horizon Oil Ltd (ASX:HZN) has moved decisively into a controlling position in Cue Energy Resources Limited after confirming it has secured a 52.21% relevant interest in the target company. The development marks a critical threshold in its off-market takeover bid and effectively places the transaction in its final stage, with the offer now declared “best and final” in terms of consideration.

The takeover structure combines both Equity and cash components, with eligible Cue shareholders entitled to receive 0.5625 Horizon Oil shares and A$0.008 in cash per Cue share. The offer is scheduled to close on 19 June 2026, subject to any extension or Withdrawal.

Market Control Reached as Acceptance Levels Cross Threshold

Horizon Oil’s announcement confirms that it has surpassed the 50.1% minimum acceptance condition, giving it a controlling stake in Cue Energy on an undiluted basis. With 366,496,315 Cue shares now held or controlled, the company has effectively secured majority ownership under Australian takeover thresholds.

This level of acceptance typically shifts a takeover from a contestable phase into a consolidation phase, where remaining procedural conditions and minority Shareholder acceptances determine final completion outcomes.

The company has also indicated that regulatory approval conditions have now been satisfied, removing one of the key execution risks that often remains late in takeover processes. As a result, the focus now shifts primarily to remaining acceptances and settlement mechanics rather than deal approval uncertainty.

“Best and Final” Declaration Signals Limited Pricing Flexibility

A central feature of the latest announcement is Horizon Oil’s declaration that its offer consideration is now “best and final.” This means the current offer structure will not be improved unless a competing or superior proposal emerges for Cue Energy.

In takeover situations, such declarations are typically used to provide price certainty to the market and encourage remaining shareholders to accept without delay. However, they also signal that upward price revisions are unlikely in the absence of external competitive pressure.

At present, Horizon Oil has stated it is not aware of any competing bid or alternative proposal for Cue Energy. This reduces the likelihood of bidding tension emerging before the offer closes.

The structure of the consideration—part scrip and part cash—also introduces exposure for Cue shareholders to Horizon Oil’s post-transaction share price performance, rather than a fully cash-exit outcome.

Deal Progression Reflects Near-Complete Execution

The takeover has progressed through multiple regulatory and procedural milestones, including the satisfaction of conditions relating to petroleum approvals in New Zealand and the Northern Territory. With these approvals now confirmed, Horizon Oil has effectively cleared most external regulatory hurdles associated with the Acquisition.

The remaining steps primarily involve acceptance processing and settlement mechanics ahead of the scheduled closing date.

The company has also disclosed that pre-bid arrangements involving a significant block of Cue shares are expected to complete shortly after the Offer Period ends, provided the transaction is declared unconditional. This further reinforces the trajectory toward full or near-full control.

Implications of Majority Ownership Without Full Compulsory Acquisition

While Horizon Oil has secured majority ownership, it has not yet confirmed whether it will reach the compulsory acquisition threshold required to fully absorb remaining minority shareholders. This distinction is important for market Liquidity and post-takeover share structure.

If the threshold is not reached, Cue Energy may continue to trade with a reduced free float, which can affect liquidity conditions for remaining shareholders. Reduced trading volumes can also lead to wider spreads and less price discovery efficiency in secondary markets.

Horizon Oil has highlighted this risk explicitly, noting that minority shareholders who do not accept the offer may face reduced liquidity and potential difficulty in selling their shares at prevailing market prices.

Such outcomes are common in partial takeover scenarios where majority control is achieved without full acquisition of remaining shares.

Strategic Rationale Behind Control Acquisition

From a strategic perspective, Horizon Oil’s acquisition of Cue Energy aligns with broader consolidation trends within the Upstream oil and gas sector. The transaction increases Horizon Oil’s exposure to Cue’s asset base while potentially enhancing operational scale and portfolio Diversification.

The combination of scrip-based consideration and control acquisition suggests a long-term integration approach rather than a purely financial acquisition. By offering Horizon Oil shares as part of the consideration, the structure also allows Cue shareholders to retain exposure to the combined entity’s future performance.

The acquisition also reflects a broader trend in energy markets where mid-tier producers seek scale efficiencies and improved Capital market positioning through consolidation.

Market Positioning and Sector Context

Within the ASX-listed energy sector, takeover activity has been influenced by fluctuating Commodity prices, capital discipline requirements, and the need for operational scale in upstream Assets. Horizon Oil’s move to consolidate ownership in Cue Energy fits within this environment of selective M&A activity focused on portfolio strengthening.

While the announcement does not include valuation commentary, the completion of majority control reduces transaction uncertainty and shifts attention toward integration outcomes and future production alignment.

Investors will likely monitor post-transaction Capital Structure impacts, particularly given the scrip component of the consideration, which introduces ongoing exposure to Horizon Oil equity performance.

Completion Timeline and Next Steps

The offer is scheduled to close at 7:00pm (Sydney time) on 19 June 2026. Remaining Cue shareholders must accept within this window, as acceptance will not be possible after the offer period expires unless extended.

With regulatory conditions now largely satisfied and majority acceptance achieved, the transaction is positioned in its final execution phase. The primary remaining variables are additional acceptances and administrative settlement processes.

Horizon Oil has encouraged remaining shareholders to accept the offer without delay, citing the absence of competing proposals and the current control position.

Conclusion

Horizon Oil’s takeover of Cue Energy has reached a decisive stage, with majority ownership secured and the offer declared best and final. The transaction now appears firmly positioned for completion, subject primarily to remaining acceptances and procedural closure. While full compulsory acquisition has not yet been confirmed, the attainment of 52.21% control significantly reduces uncertainty around deal completion. The coming weeks will determine whether Horizon Oil consolidates full ownership or proceeds with Cue Energy operating under a reduced free float structure within its broader energy portfolio.
