    Talos farmed into Repsol's Block 29 development offshore Mexico, taking a 50% working interest for a contingent $30 million payment at final investment decision plus a $20 million exploration-well cost carry. The block holds the Polok and Chinwol discoveries - over 200 million barrels of oil equivalent of gross recoverable resource - envisioned as an FPSO-based hub, extending Talos's long-running Mexican offshore exploration story (which began with the Zama discovery and Block 31 stake years earlier) alongside its newly announced Gulf of America bolt-on acquisition.

    Talos issued $800 million of new 8.000% notes due 2034, using part of the proceeds to redeem its existing 9.000% notes at a premium and the rest to help fund the pending Shell Offshore (Na Kika/Coulomb) acquisition - another step down in borrowing costs as the company keeps refinancing into cheaper debt.

  3. 30 June

    Talos agreed to another major Gulf acquisition, teaming with a Ridgewood Energy affiliate to buy Shell Offshore's deepwater Na Kika and Coulomb assets for $1.7 billion total. Talos's 50% share costs about $850 million: it becomes operator of the Coulomb field and takes a 25% interest in the BP-operated Na Kika platform and satellite fields (subject to BP's right to preferentially buy that piece itself), continuing its strategy of scaling up through Gulf of Mexico deepwater consolidation after EnVen and QuarterNorth.

    Talos fully replaced its original 2018 JPMorgan credit agreement with a new Amended and Restated Credit Agreement, holding the borrowing base and commitments at $700 million but extending the maturity out to January 2030 (subject to an earlier springing maturity if its 9.000% 2029 notes aren't refinanced in time).

    Talos's lenders cut its borrowing base and total credit commitments from $1.5 billion to $925 million, and added a new rule requiring two-thirds lender approval for further draws if total exposure ever reaches $800 million - a tightening signal following the QuarterNorth-driven expansion.

    Talos closed the QuarterNorth acquisition on March 4, 2024, issuing 24.35 million shares and paying about $1.27 billion cash, and expanded its board to nine members with QuarterNorth designee Joseph A. Mills joining - Talos's second major debt-and-equity-funded Gulf of Mexico acquisition in just over a year, continuing its consolidation strategy after EnVen.

  6. 7 Feb

    Talos issued new senior notes to fund part of the QuarterNorth cash payment and to redeem both its existing 12.00% notes and the 11.75% notes it had assumed from EnVen - consolidating its debt at lower rates (9.000% and 9.375%, per the later closing filings) in one move. If the QuarterNorth deal fell through by May 31, 2024, $340 million of the new notes would have to be redeemed immediately.

    Less than a year after closing EnVen, Talos announced another major Gulf of Mexico acquisition: a $1.29 billion deal for QuarterNorth Energy, paid in 24.8 million shares plus about $965 million cash. The deal adds roughly 30,000 barrels/day of high-margin, mostly-operated, oil-weighted production and 69 million barrels of proved reserves, with management targeting $50 million of annual synergies and a leverage ratio at or below 1.0x by year-end 2024.

    Talos closed the EnVen acquisition on February 13, 2023, issuing the 43.8 million shares and $212.5 million cash and assuming $257.5 million of EnVen's 11.75% notes. As part of closing, Talos declassified its board (moving to annual elections by 2025), Riverstone-affiliated director Robert Tichio resigned under the sponsors' support agreement, and two EnVen-designated directors (Shandell Szabo and Richard Sherrill) joined an expanded eight-member board - the last of the original 2018 sponsor-controlled board structure giving way to a more independent one.

    Talos sent shareholders the final proxy for a February 8, 2023 special meeting to vote on the EnVen merger agreed September 21, 2022. EnVen holders would get 43.8 million Talos shares plus $212.5 million in cash (subject to adjustment). Shareholder approval is needed because the share issue exceeds NYSE's 20% threshold. Riverstone affiliates, holding about 15% of the votes, have agreed to vote in favor. The meeting also covers board and bylaw changes, including declassifying the board by the 2025 annual meeting, which are not conditions to the merger. This continues the serial acquisition strategy and the unwinding of sponsor governance rights.

  2. 28 Oct

    Talos registered the shares for its purchase of EnVen Energy, another Gulf of Mexico operator: EnVen's owners take 43.8 million Talos shares plus $212.5 million in cash, the share leg big enough to force a New York Stock Exchange shareholder vote. The same meeting carries unrelated proposals to rewrite Talos's charter and bylaws, and the merger agreement sets break fees of $42.5 million payable by Talos and $28.0 million by EnVen.

  3. 22 Sept

    Talos signed the definitive merger agreement to acquire EnVen Energy: EnVen holders get 43.8 million Talos shares plus $212.5 million cash and will own about 34% of the combined company (Talos shareholders 66%), EnVen gets board representation, and Talos launched a consent solicitation on its own notes to permit assuming EnVen's debt. The deal adds about 24,000 barrels/day of high-margin, oil-weighted, mostly-operated deepwater production and roughly doubles Talos's operated deepwater facility footprint, with management guiding to $30 million of annual synergies and a post-deal net debt ratio under 0.8x.

  4. 22 Sept

    Talos announced a $1.1 billion deal to acquire EnVen Energy, a private deepwater Gulf of Mexico operator, for 43.8 million Talos shares plus $212.5 million cash - a transaction management said would boost production 40%, add oil-weighted deepwater assets, and be immediately accretive and de-leveraging.

    Talos's original 2018 sponsor board structure began unwinding: Apollo's three board designees resigned and Apollo's governance rights under the founding Stockholders Agreement were terminated entirely, with the board no longer fixed at ten members. Riverstone, the other founding sponsor, retains its board and voting arrangements.

    As commodity prices recovered, Talos extended its credit facility maturity to November 2024 and got its borrowing base raised to $950 million from a twelve-bank lending syndicate, with drawn borrowings already falling as free cash flow improved - a sharp turnaround from the prior year's distressed 12% notes. The company also disclosed it was building a new Gulf Coast carbon capture and storage business alongside its oil and gas operations.

    With oil markets still reeling from 2020, Talos issued $500 million of new 12.00% second-priority secured notes due 2026 - a high coupon reflecting the distressed financing environment E&P companies faced coming out of the pandemic price crash.

On the same day it amended its JPMorgan-led credit facility: the borrowing base fell from $1.15 billion to $985 million (with a possible further cut of up to $60 million if the deal does not close by the outside date), interest margins rose 0.25%, and new hedging and anti-cash-hoarding terms were added.

    Talos Energy, Inc. was born on paper: a new holding company (Sailfish Energy Holdings, to be renamed Talos Energy) filed to combine bankruptcy-emerged Stone Energy Corporation with privately-held, Apollo- and Riverstone-backed Talos Energy LLC. Stone shareholders would get one new-Talos share per Stone share and end up owning 37% of the combined company, with Talos's private owners holding the other 63% - creating what the filing calls a premier offshore-focused Gulf of Mexico E&P.
