I. Executive Summary
This memorandum analyzes the Swiss federal anticipatory withholding tax (Verrechnungssteuer) implications arising from the acquisition by Ardent Capital Partners III LP ("Ardent Capital" or the "Buyer") of Luminex Systems Holdings Inc. (the "Target" or "Luminex Holdings") and, in particular, the ongoing Swiss withholding tax consequences applicable to the Target's Swiss subsidiary, Luminex Systems AG ("Luminex AG"), a Swiss Aktiengesellschaft registered in the Canton of Glenrock Assurance (Commercial Register No. CHE-284.391.057), with its registered office and principal place of business at Bahnhofstrasse 71, 8001 Zürich, Switzerland.
Ardent Capital, a Delaware limited partnership headquartered at 399 Park Avenue, 42nd Floor, New York, NY 10022, is acquiring Luminex Holdings for an aggregate equity value of $2,800,000,000 (the "Transaction") by means of a reverse triangular merger under the Delaware General Corporation Law. Pursuant to the Agreement and Plan of Merger executed on March 24, 2025 (the "Merger Agreement"), Ardent Apex Merger Sub Inc. ("Merger Sub"), a newly formed Delaware corporation, will merge with and into Luminex Holdings, with Luminex Holdings surviving as a wholly owned subsidiary of Ardent Apex Holdings Inc. ("Apex Holdings"), itself wholly owned by Ardent Capital. The Transaction is expected to close in the third quarter of 2025 (July–August 2025), subject to satisfaction of regulatory and other closing conditions.
Following the closing of the Transaction, the relevant ownership chain for Swiss withholding tax purposes will be as follows:
Ardent Capital Partners III LP (Delaware LP) → Ardent Apex Holdings Inc. (Delaware corporation, EIN 93-2178435) → Luminex Systems Holdings Inc. (Delaware corporation, EIN 86-2547193) → Luminex Systems AG (Swiss AG, CHE-284.391.057)
Key Conclusions. Our principal conclusions, which are discussed in detail in the body of this memorandum, may be summarized as follows:
1. Statutory Withholding Rate. Under the Federal Act on Anticipatory Tax (Verrechnungssteuergesetz, VStG), dividends and deemed dividend distributions (verdeckte Gewinnausschüttungen) from Luminex AG to its direct parent, Luminex Holdings, are subject to Swiss federal anticipatory withholding tax at the statutory rate of 35% on the gross dividend amount.
2. Treaty Reduced Rate. The Convention between the United States of America and the Swiss Confederation for the Avoidance of Double Taxation with Respect to Taxes on Income, signed October 2, 1996, as amended by the Protocol signed September 23, 2009 (the "Treaty"), provides for a reduced withholding rate of 5% on dividends paid to a qualifying U.S. corporate shareholder that directly holds at least 10% of the voting power of the distributing Swiss company. Because Luminex Holdings (a Delaware corporation and U.S. tax resident) will directly hold 100% of Luminex AG post-closing, the 10% voting-power threshold is clearly satisfied, and the 5% reduced rate should be available — provided that Luminex Holdings satisfies the limitation-on-benefits ("LOB") requirements of Article 22 of the Treaty.
3. LOB Risk. The primary risk to the availability of the 5% treaty rate is the LOB ownership test under Article 22(2)(e) of the Treaty. The presence of Northvale Sovereign Holdings Ltd., a Cayman Islands exempted limited company, as a direct co-investor in Apex Holdings (approximately 6.9% of equity), together with the as-yet-unconfirmed residency composition of Ardent Capital's underlying limited partners, creates uncertainty as to whether more than 50% of the beneficial owners of Luminex Holdings are "equivalent beneficiaries" within the meaning of the Treaty. We recommend obtaining detailed LP composition data from Ardent Capital promptly to resolve this question.
4. Structuring Recommendations. We provide below a series of pre-closing and post-closing structuring recommendations designed to (a) ensure treaty eligibility under the LOB provisions, (b) maximize the use of the notification procedure (Meldeverfahren) in lieu of actual withholding, (c) leverage capital contribution reserve distributions under the Kapitaleinlageprinzip (capital contribution principle), and (d) prioritize non-dividend cash repatriation methods (royalties, management fees, intercompany loan repayments) to minimize Swiss withholding tax leakage in the post-closing period.
5. Significance for Deal Economics. The difference between the 35% statutory rate and the 5% treaty rate represents a tax savings of $30 per $100 of dividends repatriated from Switzerland. Given the post-closing debt-service requirements associated with the $1,200,000,000 Term Loan B and $300,000,000 subordinated notes at the Apex Holdings / Luminex Holdings level, minimizing Swiss withholding tax on cash repatriation from Luminex AG is critical to the Transaction's financial model and cash-flow projections.
This analysis has been prepared in coordination with Breitfeld Hess & Partner AG (Dr. Lukas Breitfeld, lead partner), the Buyer's Swiss local counsel, located at Talstrasse 62, 8001 Zürich, Switzerland, and Pendleton & Associates LLP (Richard Chow, Engagement Partner), the Buyer's tax and accounting advisor, located at 30 Rockefeller Plaza, Suite 2600, New York, NY 10112. We have relied upon factual information provided by Ardent Capital's deal team (Ted Hargrove, Victoria Langford, and David Ng), the Target's management (Dr. Stefan Kessler, CEO, and Annelise Gruber, CFO), and the due diligence materials assembled in the virtual data room maintained by Luminex Holdings' financial advisor. Where we have identified open factual questions material to the analysis, we have noted them in Section XII (Open Items and Next Steps) below.
II. Background and Transaction Structure
A. Transaction Overview
On March 24, 2025, Ardent Capital entered into the Merger Agreement providing for the acquisition of Luminex Holdings for an aggregate equity value of $2,800,000,000, representing $20.00 per share on approximately 140,000,000 fully diluted shares of Luminex Holdings common stock. The Transaction is structured as a reverse triangular merger in which Ardent Apex Merger Sub Inc., a Delaware corporation incorporated on March 7, 2025 (EIN 93-2178502), will merge with and into Luminex Holdings, with Luminex Holdings surviving as the surviving corporation and a wholly owned subsidiary of Apex Holdings. Apex Holdings is a newly formed Delaware corporation incorporated on March 5, 2025 (EIN 93-2178435), and is itself wholly owned by Ardent Capital.
The reverse triangular merger structure was selected in order to preserve the continuity of Luminex Holdings' corporate existence (and, critically, its existing contractual relationships, regulatory authorizations, and subsidiary ownership), while effecting a change of control at the shareholder level. Upon the effective time of the merger, all outstanding shares of Luminex Holdings common stock (other than shares held by management rollover participants, shares held in treasury, and dissenting shares, if any) will be cancelled and converted into the right to receive the $20.00 per share merger consideration in cash. Management rollover participants will contribute a portion of their merger consideration to Apex Holdings in exchange for equity interests therein, as described in Section II.D below.
The Transaction is subject to customary closing conditions, including (a) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (which has been filed and is pending as of the date of this memorandum), (b) clearance or non-prohibition under the Swiss Cartel Act and applicable EU and foreign antitrust/competition regimes, (c) resolution of any CFIUS review (a voluntary joint notice was filed on April 4, 2025, Tracking No. CFIUS-2025-0087), (d) the absence of any material adverse effect, and (e) the delivery of customary closing certificates, legal opinions, and other deliverables. The estimated closing date is in the third quarter of 2025 (July–August 2025).
B. Luminex Corporate Structure Relevant to Swiss WHT
Luminex Systems AG is a Swiss Aktiengesellschaft organized under the laws of Switzerland. It was originally incorporated as the ultimate parent entity of the Luminex group of companies and, prior to a corporate reorganization completed in 2021, served as the top-level holding and operating company. In 2021, the Luminex group underwent a reorganization pursuant to which Luminex Systems Holdings Inc. was incorporated in the State of Delaware (on June 14, 2021, EIN 86-2547193) and became the new top-level holding company of the group by means of a share exchange agreement under which each share of Luminex AG was exchanged on a 1:1 basis for a share of Luminex Holdings common stock. Following the 2021 reorganization, Luminex AG became a direct, wholly owned subsidiary of Luminex Holdings.
Luminex AG is the primary operating entity of the Luminex group and owns, directly or through its subsidiaries, the intellectual property, customer relationships, and operational infrastructure that form the core of the group's enterprise software business. The principal direct and indirect subsidiaries of Luminex AG include:
• Luminex Systems GmbH — organized under the laws of Germany, with its registered office in Munich (Handelsregister: HRB 247891, Amtsgericht München); serves as the group's central European operations hub for the DACH region;
• Luminex Systems UK Ltd. — incorporated in England and Wales (Company No. 12847362); serves UK and Nordic markets;
• Luminex Systems Pte. Ltd. — incorporated in Singapore (UEN 201924781K); serves Asia-Pacific markets; and
• Luminex Systems Inc. ("Luminex US") — incorporated in the State of Delaware; serves the North American market. Although Luminex US is a sister subsidiary of Luminex AG under Luminex Holdings (i.e., Luminex US is a direct subsidiary of Luminex Holdings, not of Luminex AG), the intercompany IP licensing arrangements between Luminex AG and Luminex US are relevant to the transfer pricing and deemed dividend analysis discussed in Section VII below.
From a financial perspective, Luminex AG generated total global revenue of approximately $487,000,000 in the fiscal year ended December 31, 2024, of which approximately $441,000,000 was annual recurring revenue ("ARR") and approximately $46,000,000 was professional services revenue. Adjusted EBITDA for the same period was approximately $121,800,000, representing a margin of approximately 25.0%. The group's key geographic markets, as a percentage of total revenue, break down as follows: DACH region (35%), North America (40%), United Kingdom and Nordics (15%), and Asia-Pacific (10%). The group employs approximately 4,200 employees globally across its offices in Glenrock Assurance, Munich, London, Singapore, and the United States.
C. Pre-Closing Ownership of Luminex AG
Prior to the closing of the Transaction, the equity ownership of Luminex Holdings (and, indirectly, Luminex AG) is as follows:
At the effective time of the merger, the shares held by Ridgeline Growth Equity Fund II LP and Meridian Venture Partners IV LP will be cancelled and converted into the right to receive the per-share merger consideration of $20.00 in cash. Management rollover participants will contribute a portion of their merger consideration as described below.
D. Post-Closing Ownership Chain for Swiss WHT Purposes
Following the closing of the Transaction, the ownership chain relevant to the Swiss anticipatory withholding tax analysis will be as follows:
Ardent Capital Partners III LP (Delaware LP) → Ardent Apex Holdings Inc. (Delaware corporation) → Luminex Systems Holdings Inc. (Delaware corporation, surviving entity) → Luminex Systems AG (Swiss AG)
The relevant dividend flow for Swiss withholding tax purposes is:
Luminex AG → Luminex Holdings → Apex Holdings → Ardent Capital
For purposes of the LOB analysis discussed in Section V below, the equity capitalization of Apex Holdings is of particular importance. The post-closing equity holders of Apex Holdings are expected to be as follows:
The total equity capitalization of Apex Holdings is expected to be approximately $2,901,000,000 (including the full face value of the management rollover), with the balance of the $2,800,000,000 purchase price (plus transaction fees and expenses) funded through a combination of the Term Loan B ($1,200,000,000) and the subordinated notes ($300,000,000). The equity / debt split implies a leverage ratio of approximately 5.1x on a total debt / 2024 Adj. EBITDA basis, which is relevant to the post-closing cash-flow analysis and debt-service requirements discussed in Section VII.D below.
III. Swiss Federal Anticipatory Withholding Tax — Statutory Framework
A. Legal Basis
The Swiss federal anticipatory tax (Verrechnungssteuer) is governed by the Federal Act on Anticipatory Tax (Bundesgesetz über die Verrechnungssteuer, VStG) of October 13, 1965 (as amended), together with its implementing ordinance (Verrechnungssteuerverordnung, VStV). The anticipatory tax is a federal tax administered and collected by the Swiss Federal Tax Administration (Eidgenössische Steuerverwaltung, SFTA / ESTV) and constitutes one of Switzerland's principal withholding tax mechanisms applicable to investment income derived by both Swiss and non-Swiss residents.
The VStG establishes the statutory framework for the imposition, collection, and refund of the anticipatory tax. The tax is characterized as a "security tax" (Sicherungssteuer) designed to ensure that investment income (including dividends, interest on certain Swiss-source debt instruments, and certain insurance payments) is properly reported for Swiss income tax purposes. For Swiss-resident recipients who properly declare the income, the anticipatory tax is fully creditable against cantonal and federal income tax liabilities or refundable. For non-resident recipients, the anticipatory tax serves as a final withholding tax, subject to reduction or refund under applicable double taxation treaties.
B. Scope and Applicability
Under Article 4(1)(b) of the VStG, the anticipatory tax is imposed on income from movable capital (Ertrag beweglichen Kapitalvermögens), including, without limitation, dividends and other profit distributions paid by Swiss-resident companies to their shareholders. The term "income from movable capital" is broadly construed and encompasses both actual distributions (cash dividends, stock dividends, and other declared distributions) and deemed distributions (verdeckte Gewinnausschüttungen), including constructive dividends arising from transactions between a Swiss company and related parties that deviate from arm's-length terms.
For purposes of the Transaction, the Swiss anticipatory tax is applicable to distributions made by Luminex Systems AG to its direct parent, Luminex Systems Holdings Inc., whether in the form of actual cash dividends or deemed dividends arising from intercompany transactions. Because Luminex AG is a Swiss-resident Aktiengesellschaft and Luminex Holdings is its sole shareholder, any dividend or deemed dividend from Luminex AG to Luminex Holdings falls squarely within the scope of the VStG.
C. Statutory Rate
The statutory rate of the Swiss anticipatory tax on income from movable capital (including dividends) is 35% on the gross amount of the distribution, as set forth in Article 13(1)(a) of the VStG. The tax is collected at source: the distributing company (here, Luminex AG) is obligated to withhold the 35% tax from the gross dividend amount and remit the withheld amount to the SFTA within 30 days of the date on which the dividend becomes due and payable (Article 16(1)(c) VStG). Failure to withhold and remit the tax on a timely basis may result in default interest and penalties.
It is important to emphasize that the 35% rate applies to the gross amount of the dividend, not the net amount. Thus, on a gross dividend of CHF 100 (or the equivalent in another currency), Luminex AG would be required to withhold CHF 35 and pay only CHF 65 to Luminex Holdings (absent application of a treaty-reduced rate or the notification procedure, as discussed in Sections IV and VI below).
D. Taxable Events Relevant to This Transaction
The following categories of taxable events under the VStG are relevant to the Transaction and the post-closing operation of the Luminex group:
1. Actual Dividends. Cash distributions from Luminex AG to Luminex Holdings constitute the most straightforward form of taxable event under the VStG. Post-closing, Ardent Capital will likely require Luminex AG to declare and pay dividends to Luminex Holdings as part of the group's cash repatriation strategy to service debt at the Apex Holdings and Luminex Holdings levels. Any such actual dividend will be subject to the 35% statutory rate (subject to treaty reduction to 5%, as discussed in Section IV).
2. Deemed Dividends (*verdeckte Gewinnausschüttungen*). Under Swiss tax law, transactions between Luminex AG and related parties (including Luminex Holdings, Luminex US, and other group entities) that deviate from arm's-length terms may be recharacterized as deemed profit distributions from Luminex AG to its shareholder. The categories of transactions most likely to give rise to deemed dividend risk in this context include:
(a) Intercompany IP licensing arrangements. Luminex AG currently licenses its intellectual property to Luminex US at a royalty rate of 4.5% of U.S. net revenues. The proposed post-closing restructured rate is 6.0% of U.S. net revenues, per the transfer-pricing benchmark study prepared by Pendleton & Associates LLP. If the Swiss tax authorities determine that the royalty rate (whether at the current 4.5% level or the proposed 6.0% level) is below arm's length — meaning that Luminex AG is not receiving adequate compensation for the value of its intellectual property — the shortfall could be treated as a deemed dividend from Luminex AG to Luminex Holdings, triggering the 35% anticipatory tax on the deemed amount (subject to treaty reduction). Conversely, if the rate is above arm's length, the excess could be recharacterized as a hidden capital contribution (verdeckte Kapitaleinlage) from Luminex US to Luminex AG, which carries different tax consequences but does not trigger Swiss anticipatory tax.
(b) Management fees and cost-sharing arrangements. Post-closing, Apex Holdings or Luminex Holdings may charge management fees or allocate shared costs to Luminex AG for centralized group services (e.g., finance, HR, legal, IT). If such fees exceed arm's-length levels, the excess may be recharacterized as a deemed dividend from Luminex AG.
(c) Intercompany loans at non-arm's-length interest rates. If post-closing intercompany financing is extended to or from Luminex AG at interest rates that deviate from arm's length, the Swiss tax authorities may impute a deemed dividend (in the case of below-market interest on loans from Luminex AG to related parties) or a deemed hidden capital contribution (in the case of above-market interest on loans to Luminex AG). The SFTA publishes annual safe-harbor interest rates for intercompany loans denominated in various currencies, and adherence to these rates is strongly recommended.
(d) Post-merger restructuring transactions. Post-closing upstream cash sweeps, distributions to fund debt service on the $1,200,000,000 Term Loan B and $300,000,000 subordinated notes, and other restructuring transactions involving Luminex AG's cash or assets could give rise to deemed dividend treatment if not structured on arm's-length terms. In particular, any cash or asset extraction from Luminex AG that is not supported by adequate consideration (e.g., a bona fide intercompany loan or arm's-length fee arrangement) risks being treated as a constructive distribution.
3. Liquidation Surplus. Upon any future liquidation or dissolution of Luminex AG, the excess of the liquidation proceeds distributed to Luminex Holdings over the paid-in capital (Nennwert and qualifying capital contribution reserves) of Luminex AG would be treated as a taxable distribution subject to the 35% anticipatory tax (subject to treaty reduction). While there is no current plan to liquidate Luminex AG, this taxable event is noted for completeness and should be borne in mind in connection with any future restructuring of the group.
4. Capital Reduction / Share Buyback. If Luminex AG were to undergo a capital reduction or repurchase its own shares from Luminex Holdings, the portion of the payment exceeding the par value (Nennwert) of the shares cancelled or repurchased would be treated as a deemed dividend subject to the 35% anticipatory tax. However, distributions out of qualifying capital contribution reserves (Reserven aus Kapitaleinlagen) are exempt from the anticipatory tax under the Kapitaleinlageprinzip (capital contribution principle), as discussed in Section VIII below.
E. Notification Procedure vs. Payment Procedure
Under the standard procedure, Luminex AG would withhold the full 35% anticipatory tax from any dividend payment to Luminex Holdings, remit the withheld amount to the SFTA, and Luminex Holdings would then apply for a refund of the treaty-rate reduction (i.e., refund of 30% if entitled to the 5% treaty rate). This refund process can take between 6 and 18 months, depending on the complexity of the application and the SFTA's processing backlog.
As an alternative, Swiss law provides a notification procedure (Meldeverfahren) under which, in lieu of actual withholding and refund, the distributing Swiss company may simply notify the SFTA of the dividend distribution and pay only the reduced treaty-rate amount (or no amount, if full relief is available). The notification procedure is available in the following principal contexts:
(a) Intra-group dividends among Swiss-resident entities: Under Article 20 VStV, Swiss corporate shareholders holding at least 20% of the capital of the distributing company may utilize the notification procedure for dividends received from Swiss subsidiaries, subject to SFTA approval.
(b) Treaty-entitled non-resident shareholders: For dividends paid to non-resident corporate shareholders that are entitled to a reduced treaty rate, the SFTA may authorize the notification procedure on a case-by-case basis, thereby allowing the distributing company to pay only the treaty-reduced amount at source. This is the relevant scenario for dividends from Luminex AG to Luminex Holdings.
The availability of the notification procedure for Luminex Holdings as a U.S. resident corporate shareholder is discussed in greater detail in Section VI below.
IV. U.S.-Switzerland Income Tax Treaty — Reduced Withholding Rate
A. Applicable Treaty Provisions
The withholding tax treatment of dividends paid by Luminex AG to Luminex Holdings is governed by the Convention between the United States of America and the Swiss Confederation for the Avoidance of Double Taxation with Respect to Taxes on Income, signed at Washington, D.C. on October 2, 1996, and entered into force on January 19, 1998, as amended by the Protocol signed on September 23, 2009, and entered into force on September 20, 2019 (the "Treaty"). The Treaty is in full force and effect as of the date of this memorandum.
The principal Treaty provisions relevant to this analysis are:
• Article 10 (Dividends): Governs the withholding tax treatment of dividends paid by a resident of one Contracting State (Switzerland) to a resident of the other Contracting State (United States).
• Article 22 (Limitation on Benefits): Contains the LOB provisions that restrict the availability of Treaty benefits to persons who satisfy specified qualifying tests, designed to prevent treaty shopping.
• Article 3 (General Definitions) and Article 4 (Resident): Define the terms "resident," "company," and other key concepts relevant to the application of Article 10.
• Article 25 (Mutual Agreement Procedure): Provides for resolution of disputes regarding the application of the Treaty between the competent authorities of the two Contracting States.
A summary of the relevant text of Articles 10 and 22 is provided in Appendix A to this memorandum.
B. Treaty Rate for Dividends
Article 10(2) of the Treaty provides for the following withholding tax rates on dividends:
(a) 5% of the gross amount of the dividends if the beneficial owner is a company (other than a partnership) that directly holds at least 10% of the voting power of the company paying the dividends (Article 10(2)(a)); and
(b) 15% of the gross amount of the dividends in all other cases (Article 10(2)(b)).
Application to the Transaction. Following the closing of the Transaction, Luminex Systems Holdings Inc. (a Delaware corporation and a resident of the United States for purposes of the Treaty) will directly hold 100% of the issued and outstanding share capital of Luminex Systems AG. This 100% direct holding clearly satisfies the 10% voting-power threshold specified in Article 10(2)(a). Accordingly, the applicable Treaty rate for dividends paid by Luminex AG to Luminex Holdings is 5%, provided that Luminex Holdings qualifies as the "beneficial owner" of the dividends (discussed in Section IV.C below) and satisfies the LOB requirements of Article 22 (discussed in Section V below).
It should be noted that the 5% rate under Article 10(2)(a) is available only to a "company (other than a partnership)." Because Luminex Holdings is a Delaware corporation (and not a partnership or other fiscally transparent entity), this requirement is satisfied. By contrast, if the direct shareholder of Luminex AG were a partnership (such as Ardent Capital itself, which is a Delaware limited partnership), the 5% rate would not be available under Article 10(2)(a), and the analysis would be significantly more complex. The interposition of Luminex Holdings (a corporation) between Ardent Capital and Luminex AG is therefore structurally advantageous for Swiss withholding tax purposes.
C. Beneficial Ownership Requirement
Article 10(2) of the Treaty conditions the reduced withholding rate on the requirement that the recipient of the dividends be the "beneficial owner" thereof. The concept of beneficial ownership is intended to exclude from treaty benefits persons who are mere agents, nominees, or conduit entities that receive dividends on behalf of, or are obligated to pass dividends through to, a third party.
Analysis. Luminex Holdings satisfies the beneficial ownership requirement for the following reasons:
• Luminex Holdings is the direct, registered, and beneficial holder of 100% of the share capital of Luminex AG. It is not acting as an agent, nominee, or trustee for any other person in holding such shares.
• Dividends received by Luminex Holdings from Luminex AG will be received for Luminex Holdings' own account and will become part of Luminex Holdings' general corporate funds.
• Luminex Holdings is not contractually obligated, under any back-to-back arrangement or similar obligation, to pass through the dividends to a specific third party that would not itself be entitled to the 5% treaty rate.
Consideration of upstream Distributions. We have considered whether the fact that, post-closing, dividends received by Luminex Holdings from Luminex AG may be further upstreamed to Apex Holdings (and from Apex Holdings to Ardent Capital) to service the group's acquisition debt could affect Luminex Holdings' status as the "beneficial owner" of the Swiss-source dividends. In our view, it does not. The mere fact that a corporate shareholder uses its after-tax income (including dividends received from subsidiaries) to pay its own obligations (including intercompany dividends to its parent) does not strip it of beneficial ownership, provided that the shareholder has legal and economic discretion over the receipt and use of the income and is not acting as a mere conduit pursuant to a prearranged pass-through arrangement with a non-qualifying person. Here, Luminex Holdings will have corporate-level discretion to determine the timing and amount of any upstream distributions to Apex Holdings, and the ultimate flow of funds to Ardent Capital occurs through ordinary corporate dividend mechanics, not through a contractual conduit arrangement. Accordingly, we conclude that Luminex Holdings' beneficial ownership of dividends from Luminex AG should be respected.
Nevertheless, we note that the SFTA has in certain cases scrutinized the beneficial ownership of intermediate holding companies in leveraged acquisition structures, particularly where the intermediate entity has no independent substance or activity apart from holding the shares of the Swiss target. To mitigate any residual risk, we recommend that Luminex Holdings maintain adequate corporate substance (board meetings, corporate records, independent decision-making regarding dividends) and that any upstream distributions from Luminex Holdings to Apex Holdings be made pursuant to separate, properly documented board resolutions, independent of the dividend declarations by Luminex AG.
D. Comparison to Statutory Rate
The following table summarizes the Swiss withholding tax savings achieved through application of the Treaty reduced rate:
Significance for Deal Model. The post-closing cash repatriation strategy from Luminex AG — necessary to fund debt service on the Senior Secured Credit Facility ($1,200,000,000 Term Loan B, priced at SOFR + 475 basis points, with an estimated all-in borrowing cost of approximately 9.0–9.5% per annum based on current forward SOFR curves) and the subordinated notes ($300,000,000, at 11.5% PIK toggle) — depends critically on minimizing Swiss withholding tax leakage. At an illustrative annual dividend of CHF 50,000,000 from Luminex AG:
• At the 35% statutory rate: CHF 17,500,000 withheld; CHF 32,500,000 received by Luminex Holdings.
• At the 5% treaty rate: CHF 2,500,000 withheld; CHF 47,500,000 received by Luminex Holdings.
• Annual savings: CHF 15,000,000 (approximately $17,250,000 at a CHF/USD exchange rate of 1.15).
Over the projected five-year hold period typical for Ardent Capital's fund investments, the cumulative savings could be material, on the order of $75,000,000 to $100,000,000 or more depending on the actual dividend amounts. The availability of the 5% treaty rate is therefore a significant economic driver of the Transaction.
V. Limitation-on-Benefits (LOB) Analysis
A. Purpose of LOB Article
Article 22 of the Treaty contains the limitation-on-benefits ("LOB") provisions, which serve as an anti-treaty-shopping mechanism. The LOB article ensures that the benefits of the Treaty (including the reduced 5% withholding rate on dividends under Article 10) are available only to bona fide residents of the United States (or Switzerland) and not to persons who have established entities in one of the Contracting States primarily for the purpose of obtaining treaty benefits to which they would not otherwise be entitled.
This is the critical gating analysis for the Transaction. If Luminex Holdings does not satisfy at least one of the LOB tests set forth in Article 22, the 5% reduced rate under Article 10(2)(a) will be unavailable, and dividends paid by Luminex AG to Luminex Holdings will be subject to the full 35% statutory rate. The financial consequences of such an outcome would be severe, as set forth in Section IV.D above.
B. Relevant LOB Tests Under Article 22
Article 22 provides several alternative tests, any one of which, if satisfied, entitles the taxpayer to Treaty benefits. We analyze below each test that is potentially applicable to Luminex Holdings.
1. Publicly Traded Company Test (Article 22(2)(c))
Under Article 22(2)(c), a company is entitled to Treaty benefits if its principal class of shares is regularly traded on a recognized stock exchange. The recognized stock exchanges for U.S. purposes include, among others, the New York Stock Exchange, the NASDAQ Stock Market, and any exchange registered with the Securities and Exchange Commission as a national securities exchange.
Analysis. Luminex Holdings is a privately held Delaware corporation. Its shares are not listed on any stock exchange and are not regularly traded in any established securities market. Following the closing of the Transaction, Luminex Holdings will continue to be privately held as a wholly owned subsidiary of Apex Holdings.
Conclusion. The publicly traded company test is not satisfied. This test is inapplicable.
2. Ownership and Base Erosion Test (Article 22(2)(e) — Derivative Benefits)
Article 22(2)(e) of the Treaty provides an alternative LOB test commonly referred to as the "ownership and base erosion" test or the "derivative benefits" test. This test has two prongs, both of which must be satisfied:
Ownership Prong. More than 50% of the aggregate vote and value of Luminex Holdings' shares must be owned, directly or indirectly, by persons who are themselves "equivalent beneficiaries." An "equivalent beneficiary" is generally defined as a resident of the United States or a resident of a third state that has an income tax treaty with Switzerland providing for a withholding rate on dividends that is equal to or lower than the rate provided under Article 10(2)(a) of the U.S.-Switzerland Treaty (i.e., 5% or lower).
Base Erosion Prong. Less than 50% of Luminex Holdings' gross income must be paid or accrued, directly or indirectly, to persons who are not residents of the United States in the form of payments that are deductible for U.S. income tax purposes (other than arm's-length payments in the ordinary course of business for goods or services and payments in respect of financial obligations to banks that are not related persons).
We analyze each prong in turn.
a. Ownership Prong Analysis. The ownership prong requires a look-through analysis of the ultimate beneficial ownership of Luminex Holdings. Because Luminex Holdings will be 100% owned by Apex Holdings, the analysis effectively looks through to the equity holders of Apex Holdings.
The post-closing equity capitalization of Apex Holdings is summarized in Section II.D above. For LOB purposes, the residency and "equivalent beneficiary" status of each equity holder (or, in the case of fiscally transparent entities such as limited partnerships, the underlying investors therein) must be determined. The following analysis addresses each major equity holder:
(i) Ardent Capital Partners III LP (approximately 24.9% of Apex Holdings equity). Ardent Capital is a Delaware limited partnership. For LOB purposes, a limited partnership is a fiscally transparent entity, and it is therefore necessary to "look through" the partnership to its underlying limited partners to determine their residency and equivalent-beneficiary status. Ardent Capital Partners III LP is a large institutional private equity fund (Fund III, vintage 2023, with total committed capital of $12.5 billion). Its limited partner base is understood to include a broad mix of institutional investors, including U.S. public and corporate pension funds, university endowments, foundations, sovereign wealth funds (including certain state-affiliated investment vehicles from the Middle East, Southeast Asia, and Northern Europe), insurance companies, and funds of funds.
The critical question is: what percentage of Ardent Capital's limited partners (by capital contribution) are residents of the United States or residents of third states that have qualifying tax treaties with Switzerland providing a 5% or lower dividend withholding rate? If, for example, a significant portion of Ardent Capital's LP base consists of sovereign wealth funds or government-affiliated entities from jurisdictions that do not have qualifying treaties with Switzerland (or that do not qualify as "equivalent beneficiaries" under the Treaty), this could reduce the share of Luminex Holdings' ultimate beneficial ownership attributable to equivalent beneficiaries below the 50% threshold.
We do not currently have detailed LP composition data for Ardent Capital Partners III LP. We understand from preliminary discussions with the Ardent deal team that a substantial majority of the fund's limited partners are U.S.-resident institutional investors, but this has not been confirmed with specificity. Obtaining this data is the single most important open item for the LOB analysis.
(ii) Management Rollover Participants (approximately 14.5% of Apex Holdings equity). The management rollover participants include Dr. Stefan Kessler (CEO, 8.5% of pre-closing Luminex Holdings shares), Annelise Gruber (CFO, 4.2%), Dr. Markus Vogt (CTO, 3.8%), and other management employees (11.5%). Of these, Dr. Kessler, Ms. Gruber, and Dr. Vogt are understood to be Swiss tax residents, while the remaining management employees are a mix of U.S. and non-U.S. residents. For LOB purposes, Swiss-resident individuals are residents of a Contracting State and therefore qualify as equivalent beneficiaries with respect to the U.S.-Switzerland Treaty. The U.S.-resident management participants likewise qualify. Non-U.S., non-Swiss management participants would need to be analyzed on a case-by-case basis to determine whether they are residents of third states with qualifying treaties.
For purposes of the ownership prong, the management rollover equity (approximately 14.5% of Apex Holdings) is likely attributable to equivalent beneficiaries, given that the principal rollover participants (Kessler, Gruber, and Vogt) are Swiss residents and the remaining management employees are predominantly U.S. or Swiss residents. However, this should be confirmed with specificity.
(iii) Northvale Sovereign Holdings Ltd. (approximately 6.9% of Apex Holdings equity). Northvale Sovereign Holdings Ltd. is a Cayman Islands exempted limited company. The Cayman Islands does not have an income tax treaty with Switzerland, and a Cayman Islands entity is therefore not an equivalent beneficiary for purposes of the LOB ownership test. This means that Northvale's 6.9% interest in Apex Holdings is attributable to a non-equivalent beneficiary, and this portion of the ownership chain counts against Luminex Holdings for LOB purposes.
We understand from Ardent Capital's deal team that Northvale is a direct-investment vehicle affiliated with a sovereign wealth fund. The identity and jurisdiction of the underlying sovereign wealth fund principal have not been confirmed for purposes of this analysis. Even if the underlying beneficial owner of Northvale is a government entity of a jurisdiction that has a qualifying treaty with Switzerland (e.g., certain Gulf states), the look-through analysis would need to be confirmed, and the interposition of the Cayman Islands vehicle may itself present difficulties depending on the applicable LOB look-through rules.
(iv) Summit Ridge Capital Partners LP (approximately 3.4% of Apex Holdings equity). Summit Ridge is a Delaware limited partnership. As with Ardent Capital, it is necessary to look through Summit Ridge to its underlying limited partners. We do not currently have LP composition data for Summit Ridge. Given the relatively small percentage of equity (3.4%), this is a secondary concern, but should be confirmed.
(v) Crestline Mezzanine Partners II LP (2.0% of Apex Holdings fully diluted equity via warrants). Crestline is a Delaware limited partnership. The warrants are not currently exercised, and Crestline's equity interest on a fully diluted basis is 2.0%. As with Ardent Capital and Summit Ridge, a look-through to Crestline's underlying limited partners would be required. Crestline is also the counterparty to the $300,000,000 subordinated notes, a fact that is relevant to the base erosion analysis discussed below.
Intermediate Analysis. Based on the available information, the ownership prong analysis is as follows:
To satisfy the ownership prong, more than 50% of the aggregate vote and value of Luminex Holdings must be attributable to equivalent beneficiaries. Taking into account Northvale's 6.9% non-qualifying interest, the remaining holders must collectively account for more than approximately 56.9% of the equity that is attributable to equivalent beneficiaries (i.e., 50% ÷ 93.1% of total equity attributable to potentially qualifying holders). If Ardent Capital's LP base is predominantly U.S.-resident (which is the expected case for a large U.S. institutional fund), and if the management rollover participants are confirmed as predominantly U.S./Swiss residents, the ownership prong should be satisfiable. However, if a significant portion of Ardent Capital's LPs are non-U.S., non-treaty-country investors (e.g., sovereign wealth funds from jurisdictions without qualifying treaties with Switzerland), the analysis becomes tighter.
Sensitivity Analysis. As an illustrative example, assume the following:
• 75% of Ardent Capital's LP capital commitments are attributable to U.S.-resident LPs (equivalent beneficiaries): 75% × 24.9% = 18.7%
• 100% of management rollover is attributable to equivalent beneficiaries: 14.5%
• 75% of Summit Ridge's LP capital is U.S.-resident: 75% × 3.4% = 2.6%
• 75% of Crestline's LP capital is U.S.-resident: 75% × 2.0% = 1.5%
• Northvale: 0% (not an equivalent beneficiary)
• Total equivalent beneficiary percentage: approximately 37.3% — this would not satisfy the 50% threshold.
This illustrative example demonstrates that the LOB analysis is sensitive to the residency composition of Ardent Capital's LP base. Even if a substantial majority of Ardent Capital's LPs are U.S. residents, the combination of Northvale's non-qualifying interest and the look-through analysis could result in a borderline outcome. Conversely, if 90%+ of Ardent Capital's LPs are U.S. residents:
• 90% × 24.9% = 22.4%
• Management rollover: 14.5%
• 90% × 3.4% = 3.1%
• 90% × 2.0% = 1.8%
• Total: approximately 41.8% — still below 50%.
This analysis reveals a structural challenge: even if all fund LPs are 100% U.S. resident, the aggregate equivalent-beneficiary percentage is:
• 24.9% + 14.5% + 3.4% + 2.0% = 44.8%
• Plus any portion of Northvale that might qualify through look-through: up to 6.9%
• Maximum: 51.7% — barely above 50%, and only if all fund LPs, management participants, and (somehow) Northvale qualify.
This is a close case that warrants careful analysis and, potentially, structural adjustments. The key variable is the computation methodology: whether the ownership test is applied at the Apex Holdings level (direct parent of Luminex Holdings) or at the Luminex Holdings level itself. Because Luminex Holdings is 100% owned by Apex Holdings, and Apex Holdings is the entity whose ownership composition is in question, the look-through is effectively to the equity holders of Apex Holdings. Under the Treaty, the ownership prong requires that more than 50% of the "aggregate vote and value" of the shares of Luminex Holdings be owned by equivalent beneficiaries. Since Apex Holdings holds 100% of Luminex Holdings, the question is whether Apex Holdings itself is an equivalent beneficiary, or whether the look-through goes further up the chain to Apex Holdings' equity holders. Under the derivative benefits provisions, the look-through extends to the ultimate beneficial owners. This means the percentages calculated above are the relevant figures.
Recommendation. We strongly recommend the following actions:
(i) Obtain LP composition data. Ryan Kowalski should coordinate with Ted Hargrove and Victoria Langford at Ardent Capital to obtain a detailed breakdown of Fund III's limited partners by jurisdiction of tax residence, including the percentage of capital commitments attributable to U.S.-resident LPs, treaty-country LPs, and non-treaty-country LPs. This is the single most time-sensitive action item.
(ii) Model equivalent-beneficiary percentages. Upon receipt of the LP data, coordinate with Pendleton & Associates LLP (Richard Chow) to model the precise equivalent-beneficiary ownership percentage under various scenarios.
(iii) Consider structural adjustments. If the analysis reveals that the ownership prong is not satisfied or is borderline, consider the following structural options:
• Restructuring Northvale Sovereign Holdings Ltd.'s investment through a U.S. Blocker corporation (a newly formed Delaware C-corporation that would be a U.S. tax resident and therefore an equivalent beneficiary). This would convert Northvale's 6.9% non-qualifying interest into a qualifying interest. However, U.S. Blocker structures carry their own tax costs (corporate-level U.S. income tax on blocker income) and should be evaluated in consultation with Northvale's advisors.
• Ensuring that the management rollover participants who are Swiss-resident individuals (Dr. Kessler, Ms. Gruber, Dr. Vogt) are treated as equivalent beneficiaries under the Treaty's reciprocal provisions. Because these individuals are Swiss residents, they are residents of one of the Contracting States and should qualify, but this should be confirmed with Dr. Breitfeld.
• If necessary, seeking a competent authority determination under Article 22(6) as a backstop (discussed in Section V.B.4 below).
b. Base Erosion Prong Analysis. The base erosion prong requires that less than 50% of Luminex Holdings' gross income be paid or accrued, directly or indirectly, to persons who are not residents of the United States in the form of payments that are deductible for U.S. tax purposes. The purpose of this prong is to ensure that the treaty claimant is not a mere conduit that receives income from Switzerland and then distributes it, through deductible payments, to non-U.S. persons.
Analysis. Luminex Holdings' principal income will consist of dividends received from Luminex AG and dividends or other income from Luminex US (its other direct subsidiary). Its principal deductible payments are expected to include:
• Interest on intercompany notes. If Apex Holdings borrows from third-party lenders and on-lends to Luminex Holdings (or if Luminex Holdings directly borrows), interest payments would be deductible. The third-party lenders — Stonebridge Credit Partners LLC, Birchwood Capital Finance LLC, Ironvale Credit Fund III LP, and Crestline Mezzanine Partners II LP — are all Delaware entities and therefore U.S. residents. Payments to U.S.-resident lenders do not erode the base for LOB purposes.
• Management fees. If Luminex Holdings pays management fees to Ardent Capital or to Apex Holdings' management company, such payments would be to U.S.-resident entities and would not count toward base erosion.
• Intercompany IP royalties. Post-closing, royalties will flow from Luminex US to Luminex AG (not from Luminex Holdings to Luminex AG). Because the royalty payments are made by Luminex US, not by Luminex Holdings itself, they should not be included in the Luminex Holdings base erosion analysis. However, if the analysis were applied on a consolidated or look-through basis (which is not the standard interpretation but has been considered by some commentators), the royalty payments to Luminex AG (a Swiss entity) could be relevant. We do not believe this is the correct interpretation under the Treaty, but flag it as a secondary consideration.
Preliminary Conclusion. Based on the foregoing, the base erosion prong is likely satisfied, as Luminex Holdings is not expected to make significant deductible payments to non-U.S. persons. The principal deductible payments (debt service) will flow to U.S.-resident lenders. This conclusion is subject to verification of the actual payment flows and deduction structures implemented post-closing.
3. Active Trade or Business Test (Article 22(2)(d))
Article 22(2)(d) provides that a resident of a Contracting State is entitled to Treaty benefits with respect to an item of income if the resident is engaged in the active conduct of a trade or business in that state (other than the business of making or managing investments, unless such activities constitute banking, insurance, or securities dealing) and the income is derived "in connection with" or is "incidental to" that trade or business.
Analysis. Luminex Holdings is an intermediate U.S. holding company whose primary activity is holding the shares of Luminex AG and Luminex US. It does not directly employ personnel or conduct operating activities. Standing alone, the "holding company" function would not ordinarily constitute an "active trade or business" for purposes of Article 22(2)(d), as the making and managing of investments is expressly excluded.
However, the question arises whether Luminex Holdings' holding activity may be considered "active" when viewed in the context of its wholly owned subsidiary, Luminex US, which conducts substantial U.S. operations. Luminex US employs approximately 1,650 employees in the United States, generates approximately $194,800,000 in annual revenue (approximately 40% of the group's global revenue), and maintains offices, customer relationships, and operational infrastructure in the United States. The dividends from Luminex AG are derived in connection with the Luminex group's global enterprise software business, of which the U.S. operations are a substantial component.
The Treaty and the Technical Explanation thereto suggest that the "active trade or business" test should be applied with reference to the substance and scope of the U.S. activities relative to the Swiss activities from which the income is derived. The "substantiality" requirement — i.e., the requirement that the U.S. trade or business be substantial relative to the activity in Switzerland that generated the income — may be satisfied here, given that 40% of global revenue is U.S.-sourced. However, the application of this test to a holding company that does not itself directly conduct the trade or business (but instead conducts it through a subsidiary) involves factual uncertainty and interpretive risk.
Preliminary Conclusion. The active trade or business test may be satisfied based on a look-through to the substantial U.S. operations of Luminex US, but this conclusion involves factual analysis and some degree of legal risk. Given the uncertainty, our preference is to rely primarily on the ownership and base erosion test under Article 22(2)(e) rather than the active trade or business test. We would consider the active trade or business test as a secondary or supporting argument.
4. Competent Authority Determination (Article 22(6))
As a fallback, Article 22(6) of the Treaty provides that if a resident of a Contracting State does not satisfy any of the objective LOB tests, that resident may request a determination from the competent authority of the other Contracting State that it is entitled to Treaty benefits. In the case of Luminex Holdings, this would involve a request to the Swiss competent authority (the SFTA), potentially in coordination with the U.S. competent authority (the Internal Revenue Service, Large Business and International Division).
This procedure is discretionary — the competent authority is not obligated to grant Treaty benefits merely because a request is made. The determination is typically based on an assessment of whether the establishment, acquisition, and maintenance of the entity in question, and the conduct of its operations, have or had as one of their principal purposes the obtaining of Treaty benefits. In practice, competent authority determinations can take 12 to 24 months (or longer) and involve significant procedural burden, including the preparation and submission of detailed factual submissions, financial information, and legal analysis.
Recommendation. We do not recommend relying on the competent authority determination as the primary LOB strategy. It should be reserved as a backstop in the event that (a) the ownership and base erosion test cannot be satisfied, (b) the active trade or business test is determined to involve unacceptable risk, and (c) structural adjustments (such as the Northvale blocker) are not feasible. If a competent authority request becomes necessary, it should be prepared in coordination with Dr. Breitfeld and filed as early as possible following closing to minimize the period of uncertainty.
C. LOB Conclusion and Risk Assessment
Primary LOB Test. Our recommendation is to rely on the ownership and base erosion test under Article 22(2)(e) as the primary basis for establishing Luminex Holdings' entitlement to the 5% treaty rate.
Key Risk Factor. The principal risk to the LOB analysis is the ownership prong, which is driven by two factors:
(i) The presence of Northvale Sovereign Holdings Ltd. (Cayman Islands) as a direct co-investor in Apex Holdings, holding approximately 6.9% of equity. Because the Cayman Islands does not have a qualifying tax treaty with Switzerland, Northvale is not an equivalent beneficiary, and its interest counts against Luminex Holdings for LOB purposes.
(ii) The residency composition of Ardent Capital Partners III LP's limited partner base. Given Ardent Capital's $12.5 billion fund (Fund III, vintage 2023) with a broad institutional LP base including sovereign wealth funds and state-affiliated pension funds from various jurisdictions, the percentage of LP capital attributable to equivalent beneficiaries (U.S. residents and treaty-country residents) is the critical unknown variable. Until detailed LP composition data is obtained and analyzed, we cannot definitively conclude that the ownership prong is satisfied.
Structural Mitigation. If the LP composition data reveals that the ownership prong is not satisfied or is borderline, we recommend the following structural adjustments:
(a) Restructuring Northvale's investment through a U.S. Blocker corporation to convert its 6.9% non-qualifying interest into a qualifying interest.
(b) Confirming that Swiss-resident management rollover participants (Kessler, Gruber, Vogt) qualify as equivalent beneficiaries under the Treaty.
(c) To the extent that Ardent Capital's LP base includes investors from third countries that have qualifying treaties with Switzerland (e.g., certain EU member states, the United Kingdom, Japan, Canada, Australia), confirming that such investors qualify as equivalent beneficiaries.
(d) As a last resort, pursuing a competent authority determination under Article 22(6).
Base Erosion Prong. The base erosion prong is preliminarily assessed as satisfied, subject to verification of actual payment flows post-closing.
VI. Notification Procedure (*Meldeverfahren*) for Intergroup Dividends
A. Overview
Under the VStG and applicable SFTA Circular Letters, Swiss corporate taxpayers may, under certain conditions, report (rather than withhold and refund) the anticipatory tax on dividends paid to qualifying recipients. This notification procedure (Meldeverfahren) is an important administrative simplification that avoids the cash-flow burden of actual withholding at 35% followed by a lengthy refund process.
In the domestic context, the notification procedure is available under Article 20 of the VStV for dividends paid by a Swiss subsidiary to a Swiss parent holding at least 20% of the capital of the subsidiary. In the cross-border context, the notification procedure may be available for dividends paid to treaty-entitled non-resident shareholders, subject to SFTA approval.
For purposes of this Transaction, Luminex Holdings will directly hold 100% of Luminex AG's share capital — far exceeding the 20% ownership threshold. The critical question is whether the notification procedure is available for dividends paid by Luminex AG to Luminex Holdings as a non-resident (U.S.) corporate shareholder.
B. Application for Notification Procedure Under Treaty
For treaty-entitled non-resident corporate shareholders, the notification procedure is applied for using Form 823B (application for notification of dividends paid by a Swiss subsidiary to a U.S. parent corporation). The Form 823B is filed with the SFTA and requires the following information, among other things:
• Identity of the distributing Swiss company (Luminex AG) and the recipient U.S. parent (Luminex Holdings);
• Confirmation of the direct and indirect ownership chain;
• Confirmation that the U.S. parent is the beneficial owner of the dividends;
• Confirmation that the U.S. parent is entitled to Treaty benefits (including satisfaction of the LOB requirements);
• The applicable Treaty-reduced rate (5%); and
• Supporting documentation, including certificates of tax residence, articles of incorporation, ownership charts, and other materials as required by the SFTA.
The application must be approved by the SFTA before the notification procedure may be used. The SFTA typically reviews the application and issues a decision within three to six months, although processing times can vary. If the application is approved, the SFTA will issue a ruling authorizing Luminex AG to apply the notification procedure for a specified period (typically three years, renewable). Under the notification procedure, Luminex AG would not actually withhold the full 35% tax; instead, it would notify the SFTA of the dividend distribution and remit only the 5% treaty-rate amount (or, in certain cases, apply the notification procedure without any payment if the SFTA grants full relief on a recurring basis, which is less common for non-resident shareholders).
C. Timing and Procedural Requirements
The notification-procedure application should be submitted well in advance of any post-closing dividend distributions from Luminex AG to Luminex Holdings. We recommend coordinating with Breitfeld Hess & Partner AG (Dr. Lukas Breitfeld) to prepare the application promptly following the closing of the Transaction, with the goal of having the SFTA approval in hand before the first planned dividend distribution.
If the application is still pending at the time of the first dividend distribution, Luminex AG will be required to withhold at the full 35% statutory rate and remit the withheld amount to the SFTA. Luminex Holdings would then need to file a refund claim for the excess withholding (35% − 5% = 30%) with the SFTA. Based on current SFTA processing times, the refund process can take 6 to 18 months, during which period the excess withholding represents a cash-flow cost to the group. This cash-flow burden should be factored into the post-closing dividend planning and debt-service cash-flow model.
To mitigate this risk, we recommend:
(a) Preparing the Form 823B application in draft form prior to closing, so that it can be filed immediately upon closing;
(b) Deferring any dividend distributions from Luminex AG until the notification-procedure approval is obtained, to the extent consistent with the group's debt-service and cash-flow requirements;
