   THE BI-WEEKLY BOTTOM LINE

   A Broad Two-Week Drawdown Meets a Live Bid for Auction Liquidity

   Summarizes the two-week period: a broad decline across covered names alongside a live tender offer in auction liquidity.

   We saw 31 of the 40 covered names fall over the two weeks, with a median move of -7.3% against a +0.8% return for the S&P 500 — a broad, not concentrated, decline. The period's clearest transaction signal was Copart's tender offer for ACV Auctions, a live bid for auction liquidity inside the covered set. Dispersion widened at the edges: Xometry returned +21.3% while EverQuote fell -22.6%. Our standing valuation frame — a 9.1x CY2027E EV/EBITDA median with a 15.5x Premium tier — held steady, so we read this period as a mark reset rather than a change to the underlying frame.

Driver attributions use calibrated language and are NeuraCap reads of the recorded evidence. Online Marketplaces Bi-Weekly Update | September 14–28, 2026 | Confidential | Not investment advice Sources & methodology 2 1 31 of 40 Covered Names Fell; The Median Move Was -7.3% The covered set moved down together over the two-week period while the S&P 500 returned +0.8%. Direction was broad rather than concentrated in one model. 2 A Tender Offer, Not a Rumour, Was the Period's Transaction News Copart, Inc. (CPRT) announced on Sep 17 that a wholly owned subsidiary commenced a tender offer to acquire ACV Auctions Inc. (ACVA). That puts a live bid on adjacent remarketing liquidity inside the covered set. 3 Dispersion Widened at Both Ends of the Set Xometry, Inc. (XMTR) returned +21.3% while EverQuote, Inc. (EVER) returned -22.6%. Roblox Corporation (RBLX) at -18.4% and ThredUp Inc. (TDUP) at -18.8% sat well below the median. 4 The Standing Valuation Frame Did Not Change This Period NeuraCap's standing sector view carries a 9.1x CY2027E EV/EBITDA median with the Premium tier at 15.5x. On our read, the period's moves are a mark reset against that frame rather than a change to it. +21.3% Best mover — Xometry, Inc. (XMTR) worst: EVER -22.6% · 9 up / 31 down of 40 covered -7.3% Sector median two-week return vs S&P 500 +0.8% 2 Transactions agreed in the two-week period from company announcements; not yet in the precedent record 1 Company filings in the window 8-K events read for driver attribution

   PUBLIC MARKET MOVERS

   The Drawdown Was Broad, but the Biggest Moves Had Names Attached

   Details the size and distribution of individual stock price moves against a sector median of -7.3% and a materiality bar of ±11.4%.

   Moves this period were broad, but the largest ones carried recorded catalysts. Against a sector median of -7.3% and a materiality bar of ±11.4%, several names moved well beyond that threshold in both directions. We link each outsized move to the filings or headlines recorded in the window, and where no driver is recorded, we say so plainly. That distinction is what tells you which moves are explained by evidence and which are still open questions.

Calibrated language throughout — NeuraCap reads, not asserted causation. Online Marketplaces Bi-Weekly Update | September 14–28, 2026 | Confidential | Not investment advice Sources & methodology 3 Bi-Weekly return per company · teal above zero, amber below · sector median -7.3% EverQuote, Inc. (EVER) -22.6% No notable in-window news was identified that clearly explains the move. The -22.6% return sat well below the sector median move of -7.3%. The period's widest single decline landed on a Discount-tier name, where the valuation base gives less cushion. UNEXPLAINED Xometry, Inc. (XMTR) +21.3% Shares moved following the Sep 15 announcement by Xometry, Inc. (XMTR) of an expanded procurement-integration partnership that places its marketplace inside customers' existing eProcurement systems Embedding into buyer procurement systems is a claim on repeat order flow, not a one-off demand push. COMPANY-SPECIFIC ThredUp Inc. (TDUP) -18.8% Shares moved following the Sep 27 report that ThredUp Inc. (TDUP) executives described a record second quarter across buyers, sellers, orders and revenue while flagging a shift toward more price-sensitive shopper behaviour. Record buyer and order counts do not settle the question when shopper price sensitivity is rising. COMPANY-SPECIFIC Roblox Corporation (RBLX) -18.4% The most likely driver was the Sep 28 broker downgrade to Underperform with a $38 price target, reported alongside a 6% decline to $43.72. Earlier in the window a target raise to $48 accompanied a 10% gain to $49. Premium-tier platforms carry the widest swing when the view on the earnings path is contested. COMPANY-SPECIFIC

   MAJOR NEWS & INDUSTRY CATALYSTS

   What Companies Did: One Acquisition Agreement, One Integration, One Legal Overhang

   Reviews the two-week period's three highest-impact company events: one acquisition agreement, one integration, and one legal overhang.

   Three events carried the most weight this period: an acquisition agreement, an integration, and a legal overhang. Each links back to its underlying filing or article, and every 'why it matters' line is our read of that record. We rank sources in a fixed order — SEC filings, press releases, then established outlets — so you know exactly what stands behind each claim. That ordering is what lets you act on this page with confidence.

"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. Online Marketplaces Bi-Weekly Update | September 14–28, 2026 | Confidential | Not investment advice Sources & methodology 4 Sep 15 · NEWS · Business Wire DoorDash agrees a strategic partnership and will acquire a campus dining business DoorDash, Inc. (DASH) is buying supply in a defined category rather than bidding for generic demand. Campus dining brings a concentrated, repeat-frequency buyer base into an existing local-commerce funnel. Category-specific supply density remains the asset large platforms are willing to pay for. Sep 15 · NEWS · GlobeNewsWire Xometry expands its procurement integration so buyers can order inside their own systems Sitting inside a customer's eProcurement workflow raises switching costs and supports order frequency without added paid acquisition. It is an owned-demand move in a business-to-business marketplace. In business-to-business marketplaces, workflow integration is the practical route to repeat buyer frequency. Sep 14 · NEWS · GlobeNewsWire Alibaba investors are pointed to an October 5, 2026 lead plaintiff deadline in a securities suit A pending securities class action is a live disclosure item for Alibaba Group Holding Limited (BABA), a Core-tier name. Litigation status is standard diligence ground for any cross-border marketplace reference set. Legal overhang sits alongside operating metrics when buyers underwrite cross-border platforms. Sep 14 · NEWS · Newsfile Corp A second firm flags the same October 5, 2026 lead plaintiff date for Alibaba shareholders Repeat notices show the claim is being actively organised rather than fading. For the sector, it keeps an unresolved item attached to one of the group's largest names. Unresolved claims stay in the file until they are settled or dismissed. Sep 14 · NEWS · GlobeNewsWire Another reminder lands on the Alibaba class action lead plaintiff deadline The volume of notices in a single window is itself observable: the matter is at the stage where investor participation is being assembled. It is a status marker, not an outcome. Period news flow can be dominated by process steps rather than operating developments. Sep 15 · NEWS · PRNewsWire A firm says it is investigating the allegations behind the Alibaba securities claim An investigation notice records that allegations are being examined; it does not establish them. On NeuraCap's read, the relevance here is timing and disclosure, not any conclusion on merit. Distinguish an announced investigation from a finding when reading platform legal news.

   M&A & STRATEGIC ACTIVITY

   Copart Puts a Live Tender Offer on the Table for ACV Auctions

   Presents Copart's tender offer for ACV Auctions against a backdrop of 40 recorded precedent transactions.

   Copart has put a live tender offer on the table for ACV Auctions, the period's one agreed transaction by company announcement. We size it against a precedent set of 40 recorded deals, using LTM multiples at announcement where disclosed. Our read on why the deal happened is exactly that — a read of the recorded evidence, not old transactions re-presented as news. For anyone tracking vehicle remarketing, this is a fresh, testable data point.

Online Marketplaces Bi-Weekly Update | September 14–28, 2026 | Confidential | Not investment advice Sources & methodology 5 AGREED IN THE PERIOD — FROM COMPANY ANNOUNCEMENTS Sep 17 · ACV Auctions Inc. (ACVA) ACV Auctions Inc. (ACVA) sits on the receiving end of a commenced tender offer from Copart, Inc. (CPRT) A vertical consolidator is reaching for adjacent auction liquidity in the same category. The record also carries a law firm's stated review of the price and process of the proposed sale, so terms will be tested before any close. Sep 17 · Copart, Inc. (CPRT) Copart, Inc. (CPRT) commences a tender offer through a wholly owned merger subsidiary to acquire ACV Buyer appetite for remarketing liquidity is live rather than theoretical. On NeuraCap's read, the logic points to demand-funnel integration and transaction and condition data rather than cost self-help. 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 the Period Changes for Operators, Buyers and Advisors

   Translates the period's evidence into implications for operators, acquirers and advisors.

   For owners and operators, a broad mark reset puts more weight on operating metrics — liquidity, take rate, retention, and contribution profit per order — rather than on the public marks themselves. For acquirers, Copart's commenced tender offer for ACV Auctions adds a live, testable reference point in vehicle remarketing where precedent transactions had been the main guide. For advisors, the clearest story to lead with is the split between the broad mark reset and the one concrete transaction in the window. These are our observations on the recorded evidence, not recommendations.

   Sources, Methodology and Important Notice

   Explains the sources and methodology behind every figure and claim in this update.

   Every figure in this update links back to the record it was taken from — filings, press releases and established outlets. We hold to a fixed reliability order and never draw on video or social platforms. That discipline is what lets you trust the numbers on every prior 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. Online Marketplaces 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. 3 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_20260929T121802Z_478_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.
