Rising Dragon Acquisition Corp.

This filing is material because the company has already secured shareholder approval for a business combination with HZJL and has an effective F-4 registration statement, but has been unable to close. The sponsor has been depositing monthly extension fees (on Jan 14, Feb 5, Mar 15, and Apr 15, 2026) to keep the SPAC alive through May 15, 2026. The current filing asks public shareholders to approve a further extension to October 15, 2027, which would give the sponsor up to 15 more months to close the HZJL deal. If not approved, the company states it will liquidate, returning trust proceeds to public shareholders. The filing also reveals significant redemption pressure: 5.7 million shares were tendered for redemption in connection with the earlier business combination vote. The trust value per share ($10.63) is far above the current trading price ($7.63), creating a strong economic incentive for further redemptions. Major institutional holders include Karpus Management (12.38%), Polar Asset Management (8.40%), RiverNorth Capital (8.32%), and others.

Without approval, RDAC may be forced to liquidate the trust and redeem public shares, ending the SPAC. The extension gives RDAC more time to close the HZJL business combination, which was already approved by shareholders in November 2025 but has not yet closed. The trust per-share value is approximately $10.896 (based on user data, not in filing), and the outcome affects redemption rights and the potential for the deal to complete.

This filing mechanically bridges the gap to May 15, 2026, using sponsor and target-designee capital to fund a short-term extension without diluting existing equity or altering the underlying merger terms. Crucially, the accompanying exhibits include a trust waiver stating that neither SZG Limited nor Aurora Beacon LLC holds any right, title, or claim to the monies in the trust account—which was initially established at US$57,787,500 pursuant to the investment management trust agreement dated October 10, 2024 with Continental Stock Transfer & Trust Company. This explicitly shields public stockholders' redemption value from these specific debt instruments. Beyond the extension mechanics and lender waivers, the filing discloses no new claims regarding customers, revenue, market size, strategy, technology, partnerships, litigation, or further personnel changes. The transaction is governed by New York law, with exclusive jurisdiction in New York courts.

The SPAC executed its business combination and extension votes, resulting in massive redemptions that depleted roughly 76% of outstanding public shares. It is now relying on monthly extension payments from sponsor and target designee to stay alive until April 15, 2026. Cash outside trust is nearly zero. The merger with HZJL Cayman Limited, valued at $350 million consideration, must close by the deadline or the SPAC liquidates.

This filing directly alters the redemption timeline and trust mechanics by depositing $200,000 into the trust account—initially established at US$57,787,500 per the prospectus referenced in the notes—to secure an extension through April 15, 2026. It signals continued deal progress toward the January 27, 2025 merger agreement with HZJL Cayman Limited, as the target's designated party is actively participating in the financing arrangement alongside the sponsor. The $10.00 conversion provision locks in a specific equity conversion metric for the lender-parties, establishing a defined participation floor independent of prevailing market prices. Crucially, Section 13 of the promissory notes explicitly waives any payee claim against the trust account itself, limiting recourse to assets held outside the trust, thereby preserving public shareholder redemption protections while aligning sponsor and target incentives through convertible debt rather than immediate equity dilution. The governing law and exclusive jurisdiction for any dispute are specified as New York courts.

The extension moves the firm deadline for either consummating the referenced merger or triggering a dissolution/redemption event to February 15, 2026, directly setting the next horizon for public shareholder redemption calculations. The sponsor and the merger counterparty each contributed $50,000 (a combined $100,000) to fund the extension, signaling continued intent to proceed while revealing the necessity of working capital injections to maintain operations past the original term. Because the notes carry zero interest, convert exclusively to IPO-equivalent units at $10.00 per unit only upon a successful transaction, and become uncollectible if terminated or unsuccessful, the sponsor and target absorb full downside risk on these funds, preventing dilution of public trust balances or senior claim encroachment. By contractually waiving recourse to the trust account, the payees preserve existing per-share trust value math for redeeming shareholders. Investors monitoring the redemption calendar should mark February 15, 2026 as the binding cutoff and watch for subsequent filings indicating whether the January 27, 2025 merger agreement advances toward closing or dissolves.

Correcting the extension fee establishes the exact monthly deduction from the trust account, preserving transparency around how the trust value of $10.896275879576413 will compound or erode under the extended timeline ending 2027-10-15. Publishing the precise tender counts quantifies shareholder exit activity immediately prior to the business combination and extension approval votes, signaling near-term trust liquidity requirements and confirming the SPAC remains in SEARCHING status as it prepares for the next corporate actions.

The registrant's filing documents a sharp contraction in the sponsor's mandatory monthly trust funding obligation, dropping to a fixed $2,703.69 per month due to the lower post-redemption share base. Investors tracking sponsor conduct and trust mechanics should note that while the dollar cost to extend the SEARCHING status decreased substantially, the fee structure is now directly tied to future redemption activity, meaning extension costs will continue to decline if additional shares are tendered prior to liquidation or a business combination. The filing confirms the Company retained shareholder authorization to extend the deadline outward through the approved monthly increments, preserving the existing redemption calendar framework while altering the economic terms of continued survival. The document contains no operational claims, revenue metrics, customer disclosures, market analysis, technology updates, partnership announcements, or litigation reports; it focuses exclusively on corporate governance actions, trust account administration, and shareholder voting outcomes.

The filing material alters the timeline and economics governing RDAC’s survival. According to the Board, approving the amendment provides the Sponsor—a Cayman Islands LLC ultimately controlled by a PRC resident—with a financial incentive to continuously fund extensions, thereby preserving the estimated $16.5 million market value of its 1,437,500 founder shares (originally purchased for $25,000) and the approximate $3.4 million value of its 254,375 private units (purchased for $2,543,750). If unapproved, the Company states it will be forced to cease operations within ten business days, redeem 100% of public shares, and dissolve, extinguishing sponsor equity and ending the HZJL merger pathway outlined in the September 26, 2025 Form F-4. Shareholders must now choose between retaining their segregated positions for the HZJL transaction or exercising the Dec 10, 2025 tender deadline for direct trust payouts. Furthermore, the disclosure emphasizes regulatory headwinds, noting that most directors and officers are PRC citizens or residents, which triggers potential CFIUS scrutiny under FIRRMA for any U.S.-target combination and heightens the risk of being deemed an unregistered investment company under the Investment Company Act of 1940 if extension proceeds exceed thresholds.

The filing confirms shareholder approval of the merger structure outlined in the January 27, 2025 Merger Agreement and referenced proxy statement (filed September 26, 2025, mailed September 29, 2025), which structures the combination through Xpand Boom Technology Inc. (PubCo) and Xpand Boom Solutions Inc. merging into HZJL Cayman Limited. Per the Company's disclosure, Bin Xiong, Wei Lin Yu, Jun Gang Wang, Jun Chen Sun, and Ye Liu were approved to serve on the PubCo board. The filing contains no claims regarding customers, revenue, market size, strategy, technology, partnerships, or litigation. The substantial redemption volume directly impacts post-combination capital availability, while the absence of extension filings or sponsor conduct modifications indicates the transaction proceeds on schedule under existing terms.

Reducing the extension cost lowers the financial friction for the Sponsor to preserve deal timelines while waiting to finalize the pending two-step merger with HZJL Cayman Limited, whose Form F-4 registration statement was declared effective September 26, 2025. The Board emphasizes that approving the amendment gives public shareholders additional time to capture the anticipated benefits of the combination, noting the Sponsor controls roughly 22.56% of issued shares and holds founder shares acquired for $25,000 and private units purchased for $2,543,750 that would be forfeited upon dissolution. Conversely, the filing warns that PRC citizenship among the Sponsor and executive team subjects potential targets to expanded CFIUS review under FIRRMA, while a 1% U.S. federal excise tax on stock repurchases could erode trust balances, meaning a failure to consummate the business combination by the Extended Date triggers liquidation procedures where only public shareholders receive pro rata trust distributions and insider interests expire worthless.

The filing confirms a signed business combination target (HZJL) at $350 million consideration. Trust value growth boosts redemption price. Sponsor is extending additional loans to keep SPAC afloat. Going concern risk remains if deal fails to close by deadline.

The one-month postponement materially resets the liquidity event horizon for public investors, extending the window to exercise redemption rights at the prevailing trust account value per share by exactly thirty days. According to the filing, the delay is intended solely to provide additional time to review the proxy materials supplemented on September 26, 2025, and to cast votes. By preserving the September 11, 2025 record date and maintaining the HZJL Cayman Limited merger structure, management signals operational continuity despite scheduling adjustments. Public shareholders must coordinate with transfer agent Continental Stock Transfer & Trust Company, LLC (Attn: Mark Zimkind) to certify share delivery before November 18, 2025, to preserve exit options. Contact Wenyi Shen at hywincapital.cn and proxy solicitor Advantage Proxy, Inc. are designated for logistical inquiries. Beyond the mechanical schedule shift, the filing contains no new revenue forecasts, customer concentrations, technology roadmaps, or litigation disclosures, relying instead on standard forward-looking statements disclaimers issued by the registrant.

Shareholders face a firm deadline to deliver signed written redemption demands and transfer shares physically or electronically via DTC to Continental Stock Transfer & Trust Company by November 18, 2025, two business days before the rescheduled vote. The board warns that beneficial owners holding RDAC Units must separate component shares sufficiently early to accommodate mailing or electronic withdrawal timelines, noting that failure to separate in a timely manner will likely prevent redemption exercise. Deal progress rests on cross-conditioned merger approvals: proposal 2 (acquiring HZJL Cayman Limited through Xpand Boom Solutions Inc.'s Merger Sub) requires approval of proposals 1 and 3, while proposal 1 (reincorporating into Xpand Boom Technology Inc./PubCo) depends on proposal 2. If either foundational merger fails, the Business Combination will not consummate. Unless the combination closes by January 15, 2026 (or extends to July 15, 2026, if the charter is amended), the company plans to dissolve and liquidate. The filing introduces five proposed post-combination directors (Bin Xiong, Wei Lin Yu, Jun Gang Wang, Jun Chen Sun, and Ye Liu) subject to shareholder ratification. Chairman Lulu Xing and the board unanimously recommend voting 'FOR' each proposal.

This filing materially shifts the SPAC exit timeline by advancing the final redemption submission window by exactly 30 days, giving public shareholders a fixed deadline of November 18, 2025, to opt out before the HZJL Cayman Limited merger vote. The Company attributes the administrative delay solely to granting additional review time for the definitive proxy statement supplemented on September 26, 2025, rather than pending target diligence or valuation adjustments. The document discloses zero financial metrics, customer bases, market positioning claims, technology disclosures, or sponsor conduct indicators; all substantive assertions are confined to procedural mechanics, the physical meeting venue at Loeb & Loeb LLP, 345 Park Avenue, New York, NY 10154, and designated contacts at Continental Stock Transfer & Trust Company, LLC and proxy solicitor Advantage Proxy, Inc. Chief Executive Officer Lulu Xing signed the report on October 15, 2025.

This filing communicates the definitive redemption deadline and trust value, which are critical for shareholders deciding whether to redeem or hold. It also details the sponsor's significant financial incentive to close the deal (founder shares worth ~$17.56 million vs. $25,000 investment), potential dilution to non-redeeming shareholders, and material risks related to the PRC holding company structure (CSRC filing, cybersecurity review, PCAOB access). These factors directly affect the redemption decision and post-combination investment outlook.

The filing confirms the ongoing business combination process with HZJL, the trust value per share exceeding the initial $10.05, and the company's limited cash runway outside the trust. The deadline to complete a business combination is January 14, 2026, with possible extension to July 2026. The sponsor continues to provide working capital support.

The Merger Agreement with HZJL provides a specific transaction for shareholders to evaluate. The trust value per share ($10.14) exceeds the IPO price of $10.05, reflecting accrued interest. The material financial updates include the trust value, working capital, and the auditor's going concern qualification. The deadline for completing a business combination is January 14, 2026 (initial), extendable to July 15, 2026.

Because the text reports zero operational, financial, or structural metrics, it carries no immediate implication for shareholder redemption behavior, trust distribution timing, or business combination execution. No assertions regarding customer bases, revenue streams, total addressable market, strategic direction, intellectual property, vendor alliances, legal exposures, or executive appointments are attributed to any individual or entity within the excerpt.

This is the definitive agreement for RDAC's initial business combination, setting the key financial and structural terms. Investors can now evaluate the target (HZJL) and the deal mechanics including the $350 million enterprise value, the trust per share of approximately $10.896 (derived from the trust amount and shares outstanding), and the substantial reliance on Chinese regulatory approvals (CSRC, ODI filings) which present execution risk. The earn-out structure provides upside if revenue targets are met. The lock-up and board control terms are standard but shift control to HZJL. No redemption mechanics or deadline for a shareholder vote are provided yet; those will appear in the proxy statement. The disclosure of the trust amount confirms the SPAC has sufficient funds to satisfy potential redemptions.

This is the first definitive transaction agreement for RDAC, moving it from a searching SPAC to a signed combination with a China-based provider of online branding, software, and supply chain services for local lifestyle businesses. It establishes the deal consideration, earn-out structure, governance (HZJL designates the post-closing board, including Bin Xiong), lock-ups, regulatory conditions including PRC/CSRC requirements, and termination mechanics. The agreement also states RDAC had at least $57,787,500 in its trust account as of signing, giving public holders a basis for evaluating the proposed redemption dynamics relative to trust value.

For investors holding RDACU, the press release establishes a definitive administrative action window requiring brokers to contact Continental Stock Transfer & Trust Company to bifurcite positions prior to the December 2, 2024 trading split. Mechanically, this creates distinct price discovery vehicles for the equity and warrant-like instruments, altering portfolio liquidity and delta exposure. From a SPAC tracking perspective, the filing confirms the entity remains in the pre-combination search phase, with no advancement toward a target announcement, redemption trigger event, or trust distribution timeline. The absence of operational disclosures leaves investors waiting for subsequent merger-related filings to assess capital deployment progress.

This is RDAC's first quarterly report, establishing baseline financials and confirming the SPAC's capital structure and trust value. Investors can track the redemption deadline (January 15, 2026, extendable to July 15, 2026) and the trust per-share value. The report also provides details on sponsor conduct and the company's search status.

For investors tracking redemption mechanics, the trust now holds exactly $57,787,500, securing a baseline distribution floor of $10.05 per redeemable share plus unallocated interest, with the underwriters contractually waiving their right to the $1,868,750 deferred commission in a liquidation scenario to protect per-share payout value. However, only $690,469 in operating cash remains on the balance sheet against $33,257 in accrued liabilities and $1,868,750 in deferred debt, requiring strict capital conservation during the business combination search. Each unit carries rights that automatically convert to one-tenth of an ordinary share upon consummation, even if underlying shares are redeemed, altering the post-combination share count for participants. Because the auditor attached a going concern qualification directly tied to the January 14, 2026 expiration, public shareholders face binary timing risk: management must identify a target meeting NASDAQ’s 80% fair market value threshold before dissolution, or trigger mandatory pro-rata redemptions. The filing notes an accumulated deficit of $(1,211,713) and zero operating revenues through the balance sheet date, confirming the entity remains in a pre-revenue formation stage with no defined geographic or sector focus for the acquisition target.

What changed: Quarterly Report (Form 10-Q) for the period ended June 30, 2026. Trust value per share increased from $10.56 at Dec 31, 2025 to $10.90 at June 30, 2026 due to interest earned, but absolute trust balance fell from $44.4M to $18.4M due to large redemptions: 1,903,823 shares redeemed at ~$10.83 on May 29, 2026 and 611,850 shares at ~$10.83 on June 3, 2026, totaling $27.3M withdrawn. The business combination deadline was extended seven times to August 15, 2026, with the last two monthly deposits of $55,637 each funded by the sponsor and the target's designee via convertible promissory notes. The merger agreement with HZJL Cayman Limited ($350M consideration) remains pending, subject to shareholder and regulatory approvals. The working capital deficit widened to $1.33M, with only $8,695 cash outside trust. The company disclosed substantial doubt about its ability to continue as a going concern. Why it matters: The filing highlights a rapidly depleting trust account and an imminent August 15, 2026 deadline. With minimal cash and a working capital deficit, the SPAC is at high risk of liquidation if the HZJL merger fails to close. Heavy redemptions signal waning public confidence. Sponsor and target are funding extensions with convertible notes, indicating ongoing commitment but also financial strain. The going concern disclosure underscores the urgency for investors monitoring the deal's completion.

What changed: A Schedule 13G — a statutory beneficial ownership report filed by UBS Group AG disclosing its equity stake in Rising Dragon Acquisition Corp. The filing segment identifies UBS Group AG as the reporting holder and references filing sequence identifier [0001610520-26-000100]. The excerpt does not contain share quantities, percentage thresholds, acquisition dates, acquisition prices, or a statement of purpose, so no measurable change in holding size or voting influence is documented in the supplied text. Why it matters: This 13G confirms institutional capital placement but does not intersect SPAC execution mechanics. The disclosure makes no reference to the trust account, redemption option pricing, any proposed amendment to lengthen the 2027-10-15 business combination window, or modifications to sponsor promissory notes, founder shares, or compensation arrangements. Because UBS Group AG did not disclose aggregate share counts, acquisition methods, or intent to influence management, the report does not signal near-term negotiation leverage, dilution events, or shifts in sponsor conduct that would alter shareholder redemption calculus. UBS Group AG attributes all reporting obligations and positional disclosures in this filing exclusively to itself as the beneficial owner.

What changed: A Form 8-K current report and supporting exhibits disclosing the entry into a material definitive agreement regarding promissory notes, alongside the creation of direct financial obligations. Per the filing executed by Chief Executive Officer Lulu Xing, Rising Dragon Acquisition Corp. reports issuing two unsecured promissory notes on June 15, 2026, each with a principal amount of $27,818.5, and a third note on July 15, 2026, with a principal amount of $55,637.41. The payees are identified as the sponsor (Aurora Beacon LLC) and SZG Limited, the designated representative of HZJL Cayman Limited, the counterparty to a merger agreement dated January 27, 2025. The registrant states the notes bear no interest, mature upon closing of the business combination, and may be converted at the holder’s election into private units identical to the IPO units at a price of $10.00 per unit. The company asserts the proceeds have been deposited into the trust account specifically to extend the business combination completion window until August 15, 2026. The exhibits further reference the trust account being initially established for an amount of US$57,787,500 pursuant to a prospectus dated October 10, 2024. Why it matters: This document directly alters the redemption deadline framework by confirming a funded extension to August 15, 2026, which halts the clock on automatic liquidation and redemptions until that date. Mechanically, the extension is financed through credit instruments rather than immediate cash draws, preserving working capital while satisfying the trust deposit requirement. For investors tracking deal progress, the filing confirms active engagement with the HZJL Cayman Limited merger pathway but provides no updates on target operations, valuation, management retention, regulatory approvals, or projected revenue or market size. The conversion feature noted in the notes carries potential dilution implications for the public share count post-combination. Absent any commercial or operational disclosures, the substantive takeaway is purely structural: the timeline has been pushed out by the registered period via sponsored and affiliate-backed debt funding, and the trust retains its protected status pending the new deadline.

What changed: Routine compliance exhibit: SEC Schedule 13G/A beneficial ownership report. The filing lists Rivernorth Capital Management, LLC as a reporting holder, but the provided text contains no numerical disclosures, transaction dates, or percentage calculations to detail any change in beneficial ownership. Why it matters: Because the document is limited to identifying the reporting entity without disclosing position sizes, acquisition costs, or voting agreements, it carries no implications for redemption deadlines, trust value preservation, extension approvals, deal advancement, or sponsor conduct. No other substantive matters—including customer relationships, revenue streams, market positioning, strategic initiatives, technological assets, partnership arrangements, litigation exposures, or executive personnel—are attributed to any party within the excerpt.

What changed: A Schedule 13G/A amended beneficial ownership report, classified as a routine SEC compliance exhibit submitted to disclose institutional shareholding status. The filing text identifies Karpus Management, Inc. as the reporting entity submitting an amendment to its Schedule 13G. The document contains no language addressing redemption deadlines, trust value movements, extension proposals, target acquisition progress, or sponsor conduct. Per the filing, there is no alteration to the stated SPAC mechanics; it functions purely as a regulatory shareholder registry update. Why it matters: This routine compliance exhibit does not impact trust account administration, redemption pricing, merger timelines, or sponsor obligations. Because the excerpt provides only the filing designation, the accession number [0001072613-26-000564], and the reporting holder’s name, it carries no substantive claims regarding customers, revenue, market size, strategy, technology, partnerships, litigation, or personnel. Attributed entirely to the filing, it confirms ongoing regulatory reporting by Karpus Management, Inc. but introduces no new terms, financial metrics, or procedural shifts relevant to investor exit rights or deal execution.

What changed: This document IS a Form 8-K Current Report functioning as a routine compliance exhibit and governance filing that records shareholder voting results, adopts a second amended and restated memorandum and articles of association, and executes a trust agreement amendment. Per the filing, shareholders approved at an extraordinary general meeting held on May 28, 2026 amendments to the company’s governing documents and investment management trust agreement. The registered change extends the combination period by fifteen one-month increments from July 15, 2026 to October 15, 2027. Following the shareholder vote, 1,903,823 ordinary shares were tendered for redemption. Based on the reduced post-redemption share count, the registrant states the monthly extension fee is fixed at $75,828.46 for each one-month extension, effectively replacing the previously contractual lesser-of-$100,000-per-month-or-$0.033-per-remaining-share formula. Voting tallies reported by the company show 3,266,304 shares voted FOR and 641,515 AGAINST on the charter amendment; 3,266,800 FOR and 640,922 AGAINST on the trust amendment; and 3,266,787 FOR and 641,030 AGAINST on the adjournment resolution. Of the 5,951,030 ordinary shares entitled to vote as of the May 1, 2026 record date, 3,907,845 cast ballots, representing 65.67% of outstanding voting power. Why it matters: The extension mechanically pushes the liquidation and redemption deadline to October 15, 2027, resetting the countdown for public holders tracking termination risk. By locking in a post-redemption sponsor deposit of $75,828.46 per month instead of the prior variable rate, the filing establishes a predictable monthly cash drain on the trust account that compounds through the final 15-month runway, directly impacting future per-share redemption valuations. The document contains no commercial claims regarding customer contracts, revenue streams, target identification, market size projections, strategic technology roadmaps, partnership pipelines, or pending litigation. Corporate governance disclosures identify Aurora Beacon LLC as the sponsor, Continental Stock Transfer & Trust Company as the trustee, and Lulu Xing as the signing Chief Executive Officer. The company’s principal executive office is listed at No. 604, Yixing Road, Wanbolin District, Taiyuan City, Shanxi Province, People’s Republic of China. While the filing provides no deal progress metrics, it materially alters the trust depletion schedule and sponsor funding obligation, making it a critical reference for investors monitoring extension viability, redemption timing, and capital preservation through the new October 2027 cutoff.

What changed: SEC Form 8-K Current Report (Items 1.01 and 2.03) classifying two unsecured promissory notes as material definitive agreements and direct financial obligations. Per the May 26, 2026 Form 8-K filed by Rising Dragon Acquisition Corp. and signed by Chief Executive Officer Lulu Xing, the company executed two promissory notes on May 15, 2026, each with a principal amount of $50,000, issuing one to sponsor Aurora Beacon LLC and the other to SZG Limited, the designee of HZJL Cayman Limited (the counterparty to the previously announced January 27, 2025 merger agreement). The notes bear zero interest, mature upon the initial business combination, and include a conversion feature allowing holders to exchange them for IPO-identical units at a price of $10.00 per unit. According to the filing, the combined proceeds were deposited into the trust account to extend the business combination completion window until June 15, 2026. The notes further disclose that the trust account was initially established at US$57,787,500 pursuant to an investment management trust agreement dated October 10, 2024. Under Section 1 of Exhibits 10.1 and 10.2, the notes terminate and require zero repayment if the merger agreement terminates under section 13.2(a) or if the business combination fails to close prior to the Closing Date for reasons not attributable to the maker. Why it matters: This filing materially shifts the SPAC’s governance and liquidity timeline by moving the mandatory liquidation and redemption cutoff to June 15, 2026, extending the window during which public shareholders may evaluate the proposed transaction or exercise redemption rights. Routing the $100,000 combined note principal into the trust rather than operating accounts preserves the per-share redemption floor while conditionally waiving repayment if the sponsor or merger counterparty walks away under the specified termination clauses. The conversion right establishes a predictable dilution pathway tied to the $10.00 unit price, and the default provisions in Sections 6 and 7 grant lenders immediate repayment rights upon insolvency, bankruptcy, or failure to satisfy principal within five business days past maturity. Investors tracking deal progress should note that the filing explicitly ties the lender’s financial exposure to the successful consummation of the HZJL Cayman Limited combination, meaning trust solvency and shareholder redemption calculations remain contingent on meeting the June 15, 2026 benchmark.

What changed: Schedule 13G – beneficial ownership report. The filing text lists AQR Capital Management, LLC, AQR Capital Management Holdings, LLC, and AQR Arbitrage, LLC as reporting entities. It provides no information regarding redemption windows, trust account allocations, extension procedures, target identification status, or sponsor fiduciary actions. As a routine compliance exhibit aggregating equity stakes, it updates public ownership registers without disclosing position sizes, purchase dates, or disposition plans that would alter shareholder liquidity expectations. Why it matters: Because the document contains no statements about customer contracts, revenue streams, total addressable markets, intellectual property, commercial partnerships, legal proceedings, or leadership changes, investors cannot extract operational or financial indicators from this submission. The absence of quantitative disclosures or forward-looking commentary means the filing does not shift redemption calculus, trigger warrant repricing events, or signal imminent business combinations. Institutional ownership updates remain informational rather than transactional until accompanied by share counts, cost bases, or Schedule 13D amendments.

What changed: A joint filing statement pursuant to Rule 13D-1(k)(1) incorporated as an exhibit to a Schedule 13G/A. The document discloses no changes or updates regarding redemption deadlines, trust value, extensions, target deal progress, or sponsor conduct. According to the filing, Kerry Propper and Antonio Ruiz-Gimenez 'hereby consent and agree to the joint filing of Schedule 13G... together with any or all amendments thereto, when and if required' for Rising Dragon Acquisition Corp. common stock. The parties also specify that this joint filing arrangement may be terminated by either undersigned individual 'upon written notice or such lesser period of notice as the undersigned may mutually agree.' Why it matters: Investors tracking SPAC mechanics and corporate substance should note this filing contains zero claims about customers, revenue, market size, strategy, technology, partnerships, litigation, or personnel. Per the explicit text, the only substantive content is the administrative consent between Kerry Propper and Antonio Ruiz-Gimenez to share 13G reporting obligations for RDAC shares. No trust account data, liquidation timelines, acquisition milestones, or sponsorship actions are reported.

What changed: Schedule 13G/A — a routine SEC compliance exhibit amending a beneficial ownership report under Section 13(d), filed by Rivernorth Capital Management, LLC. The supplied text identifies Rivernorth Capital Management, LLC as the reporting holder for a Schedule 13G/A dated 2026-05-15 but provides no amendment details, aggregate share quantities, ownership percentages, acquisition or disposition dates, or purpose statements. Accordingly, the excerpt contains no updates that affect the SPAC’s $10.896275879576413 trust per share, no information regarding the 2027-10-15 business combination deadline, no commentary on extension voting, redemption flows, or sponsor conduct, and no record of any transaction that would shift beneficial ownership thresholds or alter public float composition. Why it matters: Without Item 4 source-of-funds language, current aggregate holdings, or transaction timestamps, the filing does not indicate whether Rivernorth Capital Management, LLC increased, decreased, or maintained its position relative to the five percent reporting trigger. The absence of share counts or date stamps prevents assessment of institutional accumulation or distribution, meaning the document cannot inform redemption timing, proxy timelines, or deal viability. No claims regarding customers, revenue, market size, strategy, technology, partnerships, litigation, or personnel are present, so the document bears no substantive operational or financial commentary beyond identifying the reporting entity.
