- 02THE BI-WEEKLY BOTTOM LINE
Operators Who Turned Construction into Running Capacity Pulled Away from the Rest of The
This slide summarizes the two-week period's market moves, the leading and lagging names and the sector's key takeaways.
Across the eleven names we track, six moved lower and the median return came to -6.6%, trailing the S&P 500's +1.6% over the same window. Montauk Renewables, Inc. (MNTK) was the standout, up +32.0%, while AleAnna, Inc. (ANNA) was the weakest name at -20.1%. The gap between these two names shows that commissioned, running capacity is being rewarded more than construction-stage progress. For owners and operators, the message is clear: converting build-out into operating output is what the market is paying for right now.

(MNTK), a Premium-tier name in NeuraCap's tiering, rose +32.0% over the window, with +26.3% of that coming on its strongest single day. 3 AleAnna Was the Weakest Name in the Set AleAnna, Inc. (ANNA) fell -20.1%, well below the -6.6% median for the covered names. 4 Bloom Energy Litigation Dominated the Period's News Flow All eight curated items in the window concern the same securities class action against Bloom Energy Corporation (BE), including allegations that sourcing disclosures conflicted with a stated no-China supply chain. +32.0% Best mover — Montauk Renewables, Inc.

- 03PUBLIC MARKET MOVERS
Startup Execution and Disclosure Credibility Set the Two Extremes
This slide ranks the covered names' share-price moves for the two-week period against the sector median and the S&P 500.
Startup execution and disclosure credibility set the two extremes this period, with the sector median move at -6.6% against a materiality bar of 15.2% on a sector-relative basis. Montauk Renewables, Inc. (MNTK) rose +32.0%, with +26.3% of that move landing in a single strongest day, while AleAnna, Inc. (ANNA) fell -20.1%. The S&P 500 returned +1.6% over the same window, so the covered set trailed the broad market at the median. We read this spread as evidence that the market is pricing execution and disclosure quality name by name, not the sector as a whole.

(MNTK) +32.0% Shares moved following Montauk Renewables' announced opening of its Turkey, North Carolina facility in Sampson County; the available evidence suggests the market read newly commissioned biomethane capacity as concrete operating progress. Capacity that is running, not capacity that is planned, is what the market paid for this period. COMPANY-SPECIFIC AleAnna, Inc. (ANNA) -20.1% No notable in-window news was identified that clearly explains the move. At -20.1%, AleAnna finished far below the -6.6% median for the covered set.

- 04MAJOR NEWS & INDUSTRY CATALYSTS
One Name, One Story: Bloom Energy's Legal Overhang Owns the Window
This slide covers the two-week period's highest-impact news, dominated by litigation involving Bloom Energy Corporation (BE).
One name owns this window: every curated item concerns the same securities class action against Bloom Energy Corporation (BE), including allegations that sourcing disclosures conflicted with a stated no-China supply chain. We treat these as recorded filings and news links, not as a verdict on the underlying claims. For clients tracking supply-chain disclosure risk, this cluster of coverage is a signal to revisit how sourcing claims are worded and evidenced elsewhere in the sector. The concentration of news on one name also means the rest of the sector traded on price action alone, with little competing headline risk.

"Why it matters" lines are NeuraCap reads; each event links to its source. Sources are admitted in a fixed reliability order (SEC filings, press releases, established outlets); video and social platforms are never used. Renewable Fuels and Biofuels Bi-Weekly Update | September 14–28, 2026 | Confidential | Not investment advice Sources & methodology 4 Sep 15 · NEWS · Newsfile Corp Bloom Energy faces a further investor class-action notice as the lead plaintiff deadline nears NeuraCap's read: a live securities claim sits next to every funding and offtake conversation a capital-intensive producer is running, whatever the case's eventual outcome. Counterparty diligence in this sector now reaches disclosure history, not just plant performance. Sep 14 · NEWS · GlobeNewsWire Bloom Energy is named in a securities fraud lawsuit covering purchases over a defined class period The claim targets what investors were told rather than how the assets perform, which is a different risk from spread or credit-price exposure. Statements about supply chains carry the same weight as statements about output in this sector. Sep 14 · NEWS · GlobeNewsWire Bloom Energy investors are reminded of the approaching lead plaintiff deadline in the pending action Repeated notices through the window kept one company's legal position, rather than sector operating news, at the top of the period's flow. When litigation owns the news flow, operating progress elsewhere gets less airtime. Sep 14 · NEWS · Newsfile Corp Bloom Energy carries a pending securities class action through to the close of the period An unresolved claim is a known, dated item that buyers and lenders can price; NeuraCap's read is that it becomes a standing diligence question until it is cleared. Dated legal milestones are easier for counterparties to underwrite than open-ended uncertainty. Sep 14 · NEWS · GlobeNewsWire Bloom Energy shareholders are alerted again to the class action ahead of the filing deadline The volume of separate notices shows how much attention a single disclosure question can pull toward one name in a sector otherwise focused on capacity and credits. Attention is finite; a legal story crowds out the operating story for the whole peer group. Sep 15 · NEWS · GlobeNewsWire Bloom Energy's securities class action deadline falls inside the reporting window The deadline landing in-window is why the item recurred so often; it marks a procedural step rather than any change in the company's operations. Procedural legal dates can dominate a period's headlines without changing plant-level fundamentals.
- 05M&A & STRATEGIC ACTIVITY
A Quiet Two Weeks for Signings Leaves the Standing Marks in Place
This slide reviews the two-week period's M&A activity, noting no new signings against the standing set of 40 precedent transactions.
No new transactions were signed in this window, leaving the reference set anchored to the 40 precedent transactions already in the record. NeuraCap's CY2027E sector median of 7.8x EV/EBITDA remains the standing mark against which any future deal will be measured. A quiet two weeks for signings does not change the multiples buyers and sellers are working from; it simply means the existing marks stayed in place. For acquirers, this is a moment to revisit the precedent set and tiering rather than wait for a new print to reset expectations.

The reference set therefore still rests on the 40 precedent transactions already in the record, against NeuraCap's standing CY2027E sector median of 7.8x EV / EBITDA.

- 06WHAT IT MEANS
What a Two-Week Period Without Signings Still Tells You
This slide translates the two-week period's evidence into implications for owners, acquirers and advisors.
For owners and operators, commissioned capacity was the period's reward, with Montauk Renewables, Inc. (MNTK) up +32.0% after moving a project from build to running. For acquirers, the reference set did not change: with no transactions signed, the 40 precedent transactions and NeuraCap's tiering remain the marks, running from a Discount range below 6.2x to a Premium range at 8.7x and above with a 9.7x median. For advisors, the clearest evidence points to leading with commissioning progress and disclosure quality, given the Bloom Energy Corporation (BE) news cluster. Together these observations argue for treating capacity delivery and disclosure clarity as the two levers most visibly priced by the market right now.

FOR ADVISORS Lead with Commissioning Progress and Disclosure Quality The period's clearest evidence is a Premium-tier name rewarded after announcing a facility opening, and a full window of news flow tied to one securities class action at Bloom Energy Corporation (BE).

Every figure in this update links back to the filing, price record or transaction it was taken from, and the underlying publishers and filings for the period are listed on this page.

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. Renewable Fuels and Biofuels 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. 2 names below the floor were excluded from movers and statistics for 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_20260928T074200Z_315_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.

The universe is the 11 listed companies whose core business is Renewable Fuels and Biofuels 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.

(FF), Gevo, Inc. (GEVO), Green Plains Inc. (GPRE), Montauk Renewables, Inc.

Window and company universe
This update covers Renewable Fuels and Biofuels over the 14-day window September 14–28, 2026; market data runs through September 28, 2026. The universe is the 11 listed companies whose core business is Renewable Fuels and Biofuels 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. Companies covered: Aemetis, Inc. (AMTX), AleAnna, Inc. (ANNA), Bloom Energy Corporation (BE), Babcock & Wilcox Enterprises, Inc. (BW), Clean Energy Fuels Corp. (CLNE), FutureFuel Corp. (FF), Gevo, Inc. (GEVO), Green Plains Inc. (GPRE), Montauk Renewables, Inc. (MNTK), REX American Resources Corporation (REX), Valero Energy Corporation (VLO). 2 names below the floor were excluded from the statistics: OPAL, SCAG.
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.
