1 / 7 · ENERGY › ENERGY › OIL AND GAS EXPLORATION AND PRODUCTION

Executive summary

Every covered producer fell over the two weeks, with a median move of -7.3% against a +1.6% S&P 500, while buyers still closed two acquisitions and Expand Energy priced $500,000,000 of senior notes. The evidence points to a market pricing risk broadly across the set rather than name by name, even as deal and financing activity stayed live through the drawdown.

Key findings

All 51 covered names fell; median move -7.3% vs S&P 500 +1.6%
Steepest declines hit smaller, discount-tier producers in the set
BKV closed Barnett assets; Talos closed a Gulf of America bolt-on
Expand Energy priced $500,000,000 of 5.650% notes; debt markets stayed open

THE BI-WEEKLY BOTTOM LINE
A Uniform Drawdown in the Shares, Steady Clearing in the Asset Market
Summarizes the two-week period: a uniform decline in covered share prices alongside two closed acquisitions.
Every one of the 51 names we cover fell over the period, for a median move of -7.3%, while the S&P 500 returned +1.6% — the direction was set across the whole set, not by any single name. At the same time, two acquisitions closed: BKV Corporation's purchase of Barnett Shale assets and Talos Energy's Gulf of America bolt-on. Expand Energy also priced $500,000,000 of 5.650% senior notes, showing that debt capital stayed open for scaled balance sheets. So what: pricing reset broadly even as deal and financing markets kept functioning — the two aren't the same signal.

The direction was set across the whole covered set rather than by individual names. 2 Two Acquisitions Closed While Prices Reset BKV Corporation (BKV) completed its purchase of Barnett Shale upstream, midstream and carbon capture assets on Sep 15, and Talos Energy Inc. (TALO) completed a Gulf of America deepwater bolt-on on Sep 22. Buyers kept transacting through the drawdown. 3 Debt Capital Stayed Open for Scaled Balance Sheets Expand Energy Corporation (EXE) priced $500,000,000 of 5.650% senior notes due 2031 on Sep 15. Balance sheet capacity through the cycle remains one of the sector's clearest separators. 4 The Standing Band Was Not Rearranged by the Move Our standing view prices the set around a CY2027E median of 4.2x EV / EBITDA, with Premium at 6.1x and Discount at 2.7x. This period's selling reached every covered name, with the deepest cuts in Discount-tier producers. -0.2% Best mover — TotalEnergies SE (TTE) worst: ANNA -20.1% · 0 up / 51 down of 51 covered -7.3% Sector median two-week return vs S&P 500 +1.6% 2 Transactions agreed in the two-week period from company announcements; not yet in the precedent record 3 Company filings in the window 8-K events read for driver attribution

PUBLIC MARKET MOVERS
The Steepest Cuts Landed on Smaller and Discount-Tier Producers
Ranks share-price moves across the covered set and shows the steepest declines concentrated in smaller, discount-tier producers.
The sector median move was -7.3% against a materiality bar of +11.0%, and the cuts were steepest among smaller and discount-tier producers. We only attach a driver where a filing or headline in the window supports it; where none is recorded, we say so. So what: separating uniform market repricing from company-specific catalysts helps you know which names warrant a fresh look versus which simply moved with the tape.

UNEXPLAINED Matador Resources Company (MTDR) -15.7% No notable in-window news was identified that clearly explains the move. Matador Resources Company (MTDR), a Discount-tier name in our standing view, fell -15.7% against a -7.3% median for the covered set. A scaled Permian operator moving with the set shows the repricing was broad, not selective. UNEXPLAINED Sable Offshore Corp. (SOC) -19.5% No notable in-window news was identified that clearly explains the move. Sable Offshore Corp. (SOC) fell -19.5% over the two-week period, well beyond the -7.3% median for the covered set. Discount-tier names absorbed the largest declines in a window where every covered name fell. UNEXPLAINED Mach Natural Resources LP (MNR) -16.7% No notable in-window news was identified that clearly explains the move. Mach Natural Resources LP (MNR) fell -16.7%, against a -7.3% median for the covered set, with its largest single day on Sep 15 at -10.3%.

MAJOR NEWS & INDUSTRY CATALYSTS
Operators Traded Assets, Funded Debt and Refreshed Leadership
Lists the two-week period's highest-impact operator events across asset sales, debt financing and leadership changes.
Operators used the window to trade assets, fund debt and refresh leadership — each event here links back to its underlying filing or article. Expand Energy's $500,000,000 note pricing at 5.650% stands out as evidence that capital markets stayed open through the drawdown. So what: these events are the operational signals worth tracking even while share prices moved as one block.

Oil and Gas Exploration and Production Bi-Weekly Update | September 14–28, 2026 | Confidential | Not investment advice Sources & methodology 4 Sep 16 · NEWS · PRNewsWire Chord Energy agreed to sell its entire non-operated Marcellus position. Non-operated, fragmented working interests are a drag on upstream value; pruning them concentrates capital on operated acreage. The agreement also shows the asset market clearing for gas-weighted non-operated packages. Public operators are still selling non-core positions to fund core development. Sep 15 · 8-K · SEC EDGAR Ecopetrol said a board member will step down, effective September 15, 2026. Board composition at a Core-tier name shapes how the price deck, the capital budget and reserve replacement choices get approved. Governance changes precede capital allocation changes more often than they follow them. Sep 15 · 8-K · SEC EDGAR Ecopetrol's acting CEO retired and the board promoted its finance chief into the role. A finance-led appointment at a Core-tier producer is the kind of signal that usually points to discipline on spend and balance sheet. NeuraCap read: watch the next capital budget for confirmation. Leadership seats decide the reinvestment rate long before the drill bit does. Sep 15 · NEWS · Business Wire TotalEnergies signed a three-year partnership to build AI models for reservoir and geoscience work. Subsurface interpretation feeds type curve, spacing and cycle-time assumptions, which is where drilling economics are actually decided. Subsurface edge is being bought as well as built. Sep 15 · NEWS · Business Wire Credit ratings were withdrawn on a BP captive insurance subsidiary after its dissolution. This is a housekeeping step in BP p.l.c. (BP)'s insurance structure rather than a change to the asset base or capital plan. Not every symbol-linked headline touches upstream operations. Sep 15 · NEWS · GlobeNewsWire Expand Energy priced $500,000,000 of 5.650% senior notes due 2031. A Core-tier gas producer clearing a benchmark-size note offering while the whole covered set fell says debt capital stayed available to scaled balance sheets. Funding access separated the larger balance sheets from the rest this period.

M&A & STRATEGIC ACTIVITY
Buyers Closed on Barnett and Gulf of America Assets Through the Drawdown
Details the M&A activity that closed or was announced in the period against the backdrop of 40 recorded precedent deals.
Two deals were agreed or closed by company announcement during the window: BKV Corporation's completed purchase of Barnett Shale assets and Talos Energy's completed Gulf of America bolt-on. These sit against a precedent set of 40 recorded deals we track for multiple context. So what: buyers kept transacting through the price drawdown, which tells you the asset market and the equity market are reading the cycle differently right now.

BKV Corporation (BKV), a Premium-tier name in our standing view, added operated scale and integrated gathering in a basin it already works. Terms were not disclosed, so the record gains a transaction without a public price. Sep 22 · Talos Energy Inc. (TALO) Talos Energy closed a bolt-on acquisition of Gulf of America deepwater oil assets. Talos Energy Inc. (TALO) sits in the Discount tier of our standing view, and the completion shows smaller operators still adding liquids-weighted production through the asset market rather than only through the drill bit. Terms and multiples enter the precedent record once the filing is processed; the reference set alongside is unchanged. 40 Recorded precedent transactions the reference set buyers and sellers price against

WHAT IT MEANS
What a One-Way Period and Two Closings Change for You
Translates the period's price move and two closings into implications for operators, acquirers and advisors.
For owners and operators, cost and decline discipline matter most when every name in the set moves together. For acquirers, the reference set gained two closings — BKV on Barnett and Talos on Gulf of America — plus Chord Energy's agreed sale of its non-operated Marcellus position. So what: for advisors, the story to lead with is what closed, not where prices landed, because the closings are the harder evidence.

SOURCES & METHODOLOGY Sources, Methodology and Important Notice How this bi-weekly update is built and what each kind of statement rests on · September 14–28, 2026 · market data through 2026-09-28 Every figure in this update links to the record it was taken from; the publishers and filings drawn on for the period are listed above. Oil and Gas Exploration and Production Bi-Weekly Update | September 14–28, 2026 | Confidential | Not investment advice 7 OBSERVED DATA Bi-Weekly stock moves are computed close-to-close over the stated window from the platform’s price series. Deal records, values and multiples come from the platform’s transaction record (SEC 8-K extractions) exactly as recorded; each figure links to its citation. Treasury rates come from the platform’s Treasury series and are shown only when the 10-year moved at least ten basis points over the window (it did not in this window, so no rate figures appear). UNIVERSE QUALITY The update universe is the platform’s approved company set for this sector, subject to a $100M market-cap floor so small, loosely related names cannot dominate the statistics. No covered name fell below the floor in this window. EVENTS & NEWS Company events are in-window 8-K filings; news items are publisher-sourced headlines fetched for the window (and any externally supplied items, marked as such). Operational and strategic developments (deals, partnerships, launches, expansion, guidance, leadership, regulatory outcomes) are shown first; capital-return mechanics and conference appearances are limited to one each. Every event links to its source. The deck never asserts an event that has no linked record. SOURCE HIERARCHY News is admitted in a fixed order of reliability: SEC filings first, then company press releases and investor-relations communications, then transaction documents, then established outlets (Reuters, CNBC, The Wall Street Journal, Barron’s and peers). Video and social platforms — including YouTube — are never used as sources. DRIVER ATTRIBUTION A stock move is linked to an event only when the event falls inside the window, and only in calibrated language ("the move appears to reflect…", "shares moved following…"). Where no driver is recorded, the page says so and compares the move to the sector median instead. ANALYTICAL INTERPRETATION "Why it matters", "why the deal happened" and the what-it-means page are NeuraCap analytical views drawn from the recorded evidence, and are labeled as such. INHERITED CONTEXT The standing sector view (thesis, valuation lens, sector median and tiering) is inherited from the NeuraCap sector study run_20260928T084245Z_302_prod (market data as of 2026-09-28) — distilled, never re-derived. That report’s own sources page governs its content; this update reads the period against it. IMPORTANT NOTICE This report is informational only. It is not investment advice, not a recommendation to buy or sell any security, and not an offer of any kind. Readers should perform their own diligence before acting on anything described here.

Sources and methodology

The universe is the 51 listed companies whose core business is Oil and Gas Exploration and Production under NeuraCap's industry classification, subject to a $100M market-capitalisation floor so that very small, loosely related names cannot dominate the movers and statistics.

Window and company universe

How the moves and statistics are computed

Each company's period move is the change in closing price from the last close before the window to the last close inside it (close-to-close). The sector median is the median of those moves across the covered names; the index return is computed the same way for the S&P 500 over the same dates. The largest single-day move inside the window is shown for each mover. Movers are the largest gainers and losers by period move; the attribution cards prefer movers whose in-window record explains the move. Movers carry the valuation tier assigned in the standing sector study (the latest NeuraCap sector outlook) where that study rated them.

Events, news and how a move is attributed

Company events are the 8-K filings made inside the window; news items are publisher-sourced headlines for the window, admitted in a fixed order of reliability: SEC filings first, then company press releases and investor-relations communications, then established outlets (Reuters, CNBC, The Wall Street Journal, Barron's and peers). Video and social platforms are never used. A move is linked to an event only when the event falls inside the window and only in calibrated language; where nothing in the record explains a move, the update says so rather than speculating. Every event links to its source.

Transactions in the window and the trailing record

Transactions are taken from SEC filings by announcement date; 0 were announced inside the window. The trailing record of 40 recorded transactions provides the reference multiples (EV over last-twelve-month revenue or EBITDA at announcement, as disclosed). A value whose own citation describes something other than the price paid is not shown as the deal value; transactions where the acquirer and the target are the same entity are treated as reorganisations and excluded.

Sources

Prices and index levels are market data through September 28, 2026; filings are the companies' SEC filings on EDGAR; press releases are the companies' own; other news items are from the established outlets named on each card; Treasury yields are published by the U.S. Department of the Treasury. Every figure and every event in the update links to its record.

Interpretation and important notice

'Why it matters', 'why the deal happened' and the what-it-means page are NeuraCap analytical views drawn from the recorded evidence, labelled as such. The update is informational: it is not investment advice, not a recommendation to buy or sell any security and not an offer of any kind.

This report is published for information only. It is not a recommendation to buy or sell any security, an offer or solicitation, an appraisal or a fairness opinion, and no fiduciary relationship is created by reading it. Multiples that fail NeuraCap’s plausibility gates are excluded and never plotted. See the full methodology and the disclaimer.
