Allstream Insiders Summary

Talos Energy has signed a definitive agreement with Shell Offshore to jointly acquire producing deepwater oil and gas interests in the Mississippi Canyon area of the Gulf of America alongside an affiliate of Ridgewood Energy Corporation.

The buyers’ total unadjusted consideration is $1.7 billion, with Talos responsible for $850 million before purchase-price adjustments. Talos expects its cash payment at closing to be approximately $450 million to $500 million, excluding its deposit, after applying estimated cash generated by the acquired interests since the transaction’s July 1, 2025 effective date. The final amount remains subject to the actual closing date and contractual adjustments.

If the full transaction closes as proposed, Talos would receive:

• A 50% working interest and operatorship in the Coulomb field.
• A 25% non-operated working interest in the BP-operated Na Kika platform.
• A 25% non-operated working interest in the Kepler, Ariel, Fourier and Herschel fields associated with Na Kika.

The interests Talos proposes to acquire produced approximately 16,000 barrels of oil equivalent per day (boe/d) during the first quarter of 2026 and were approximately 77% oil. Talos attributes approximately 23 million barrels of oil equivalent (MMBoe) of proved reserves and 10 MMBoe of probable reserves to its proposed interests, net of plugging and abandonment obligations.

The acquisition has not closed. Completion is expected by the end of 2026, subject to regulatory and customary conditions. BP also holds a 30-day preferential right covering the Na Kika interests. If BP exercises that right, Talos would acquire Coulomb but not the proposed Na Kika and associated-field interests.

What Talos Energy Is Proposing to Acquire

Shell currently owns the entire Coulomb tieback and a 50% non-operated interest in Na Kika and the four named fields. Under the purchase agreement, Talos and Ridgewood would each acquire one-half of Shell’s divested interests. That would leave Talos and Ridgewood with 50% each in Coulomb and 25% each in the Na Kika interests, while BP would retain its existing 50% Na Kika position and operatorship.

The transaction does not make Talos the operator of Na Kika. Talos would operate Coulomb and participate as a non-operating partner in the BP-led Na Kika assets.

Na Kika Is the Producing Hub for the Acquired Fields

Na Kika is a deepwater semi-submersible production platform that began operating in 2003. The platform serves as the host for production from multiple Mississippi Canyon fields, including Kepler, Ariel, Fourier and Herschel.

Coulomb began production in 2005 as a subsea tieback to Na Kika. Although Talos would become operator of the Coulomb field under the proposed transaction, Coulomb’s production remains physically linked to the BP-operated host platform.

That relationship creates two distinct operational roles. Talos would control field-level decisions for its operated Coulomb interest, while BP would continue managing the Na Kika host and the associated BP-operated fields. Development, maintenance and production plans involving the shared infrastructure would continue to require coordination among the owners and operator.

Shell described Na Kika as its only non-operated Gulf of America platform. BP owns the remaining 50% working interest and operates the facility.

The Proposed Interests Add Oil-Weighted Production and Reserves

Talos reported that its proposed interests averaged approximately 16,000 boe/d during the first quarter of 2026, with oil representing about 77% of production.

The reserve estimates net to Talos are:

• 23 MMBoe of proved reserves.
• 10 MMBoe of probable reserves.
• 33 MMBoe of combined proved and probable reserves based on the disclosed categories.

Talos said the figures are based on an NSAI year-end 2025 reserves report and are net of plugging and abandonment obligations. Reserve estimates remain subject to reservoir performance, commodity conditions, future development decisions and the final assets transferred at closing.

These production and reserve figures apply specifically to the interests Talos proposes to acquire. They are not Talos company-wide operating totals. They also assume BP does not exercise its preferential purchase right over the Na Kika interests.

Talos’s Consideration Is Part of a $1.7 Billion Joint Purchase

The SEC filing identifies an unadjusted aggregate purchase price of $1.7 billion for the interests being purchased jointly from Shell. Talos and Ridgewood are each responsible for an unadjusted $850 million share if all assets transfer.

Talos placed $42.5 million in escrow when the agreement was signed. That deposit will be credited toward the amount due at closing.

Because the transaction has an economic effective date of July 1, 2025, cash generated by the assets between that date and closing is expected to reduce Talos’s final payment. Talos currently estimates a closing payment of approximately $450 million to $500 million, excluding the deposit. That range assumes an estimated closing date and should not be presented as the final purchase price until the acquisition closes and adjustments are completed.

If BP exercises its preferential right, the Na Kika interests would be removed from the transaction and the purchase price would be reduced by their allocated value. The public disclosures do not provide a separate value for Coulomb or for each Na Kika field.

BP’s Preferential Right Could Change the Asset Package

BP has a 30-day preferential purchase right over Shell’s interests in the Na Kika platform and the Kepler, Ariel, Fourier and Herschel fields. The right does not apply to Coulomb.

There are therefore two possible asset outcomes:

1. BP does not exercise the right: Talos acquires a 50% operated interest in Coulomb plus 25% non-operated interests in Na Kika and the four associated fields.
2. BP exercises the right: Talos acquires the 50% operated Coulomb interest, while the Na Kika interests are excluded and Talos’s purchase price is reduced.

Until the preferential-right period expires and closing is confirmed, the full Na Kika package should be described as proposed rather than acquired.

The acquisition is also subject to government approvals, applicable antitrust waiting periods, the accuracy of contractual representations and satisfaction of other closing conditions. Talos and Shell expect closing by the end of 2026, but the purchase agreement provides no assurance that every condition will be completed on that schedule.

Infrastructure-Led Exploration Could Extend the Asset Life

Talos identified infrastructure-led exploration, or ILX, as a central source of future upside. ILX targets prospects that may be developed through existing platforms, pipelines and subsea systems rather than requiring a new standalone production facility.

Talos said it sees a pathway for operated development activity associated with the acquisition to compete for capital beginning in 2027. The most direct operated position would be Coulomb, while any new Na Kika-hosted development would require coordination with BP and the other platform owners.

The acquisition announcement does not name an ILX prospect, disclose recoverable-resource estimates, provide a well count, assign capital or establish drilling and first-production schedules. It therefore signals a future development inventory without sanctioning a specific project.

Shell will retain conditional economic interests tied to future activity, including overriding royalties on production from certain new leases using the Na Kika platform. Those provisions reinforce the possibility of new tiebacks but do not establish that a particular well or field has reached final investment decision.

Buyers Will Assume Decommissioning Responsibilities

Shell said the transaction includes the buyers’ assumption of certain decommissioning obligations and related security requirements. Those obligations can include future well plugging and abandonment, subsea equipment removal and facility retirement responsibilities allocated under the purchase agreement and applicable regulations.

Talos’s disclosed reserve estimates are net of plugging and abandonment. The companies have not published an asset-by-asset decommissioning schedule, execution budget or contractor plan.

The transaction also preserves Shell Trading US Company’s offtake rights for Na Kika and Coulomb under agreements negotiated with the buyers. Those commercial arrangements affect how production will be marketed after closing but do not change BP’s platform operatorship or Talos’s proposed field interests.

What the Acquisition Could Mean for Offshore Contractors

The immediate transaction is an ownership change, not a new offshore construction award. Talos’s planned ILX and field-life-extension work could eventually create activity across:

• Subsurface imaging and reservoir evaluation.
• Deepwater drilling and completion services.
• Subsea trees, controls, manifolds and flowlines.
• Tieback engineering and installation.
• Platform modifications and brownfield integration.
• Inspection, maintenance and production optimization.
• Well intervention and workover services.
• Plugging, abandonment and decommissioning scopes.

Allstream Perspective

The proposed acquisition gives Talos two different forms of deepwater exposure: an operated position in the Coulomb field and non-operated participation in the BP-run Na Kika production hub. That combination adds current oil-weighted production while positioning Talos to evaluate future tiebacks around established Mississippi Canyon infrastructure.

The most important unresolved issue is BP’s preferential purchase right. Exercising it would materially narrow the Talos package to Coulomb and reduce the purchase price. Closing and the final asset composition must therefore be confirmed before the transaction is treated as complete.

For the offshore supply chain, the near-term event is the ownership transition. The longer-term opportunity depends on whether Talos advances the identified ILX inventory into named wells, subsea tiebacks and platform modifications beginning in 2027 or later. None of those development projects has yet been sanctioned in the public acquisition materials.
