Dr. Lukas Breitfeld Breitfeld Hess & Partner AG Talstrasse 62 8001 Zürich, Switzerland
Dear Dr. Breitfeld:
Re: Acquisition of Luminex Systems Holdings Inc. by Ardent Apex Holdings Inc. — EU Foreign Subsidies Regulation Notification (Regulation (EU) 2022/2560); EU FSR Case No. FSR.M.2025-0412
1. Introduction and Purpose
Calderwood & Harkness LLP represents Ardent Capital Partners III LP ("Ardent Capital" or the "Buyer"), a Delaware limited partnership headquartered at 399 Park Avenue, 42nd Floor, New York, NY 10022, in connection with the proposed acquisition (the "Transaction") of Luminex Systems Holdings Inc. ("Luminex Holdings" or the "Target"), a Delaware corporation with operational headquarters at 2100 Reston Gateway Drive, Suite 800, Reston, VA 20191. As you are aware from prior correspondence and discussions, the Transaction has significant cross-border regulatory implications, including under the European Union's Foreign Subsidies Regulation.
The purpose of this letter is to instruct Breitfeld Hess & Partner AG ("Breitfeld Hess"), as the Buyer's Swiss and EU local counsel, to prepare, finalize, and submit an EU Foreign Subsidies Regulation notification (the "FSR Notification") to the European Commission (the "Commission") pursuant to Regulation (EU) 2022/2560 of the European Parliament and of the Council of December 14, 2022, on foreign subsidies distorting the internal market (the "EU FSR" or the "Regulation"), and specifically Article 21 thereof, which governs the notification obligations applicable to concentrations meeting the thresholds set forth in Article 20 of the Regulation.
This instruction letter supplements and should be read in conjunction with our prior instruction letter dated April 4, 2025, pursuant to which we instructed Breitfeld Hess to prepare and file notifications with the Swiss Financial Market Supervisory Authority ("FINMA"), the State Secretariat for Economic Affairs ("SECO"), and the Swiss Competition Authority ("COMCO") (Swiss Competition Authority File No. 32-0973). We request that Breitfeld Hess coordinate the preparation of the FSR Notification with the Swiss filings to ensure consistency in the description of the parties, the transaction structure, competitive dynamics, and revenue and market share data across all regulatory submissions.
The target filing date for the FSR Notification is April 11, 2025. Given the compressed timeline, we respectfully request that Breitfeld Hess prioritize allocation of resources to the preparation of this filing and promptly advise us of any anticipated difficulties in meeting this deadline.
The responsible partner at Calderwood & Harkness for M&A matters relating to this Transaction is James Prentice. Antitrust and competition matters are coordinated by Elaine Forsythe, Specialist Partner, Antitrust & Competition. The working associate contact at Calderwood & Harkness for purposes of the FSR Notification is Megan Chu, who may be reached at mchu@calderwoodharkness.com and +1 (212) 555-0194. All working-level communications regarding the FSR Notification should be directed to Megan Chu, with copies to James Prentice and Elaine Forsythe as appropriate.
2. Transaction Overview
We provide below an overview of the Transaction for purposes of preparing the FSR Notification. Additional detail, including the fully executed transaction documents, is provided in the enclosures to this letter and will be supplemented as needed during the drafting process.
2.1 Structure. The Transaction is structured as a reverse triangular merger under the Delaware General Corporation Law ("DGCL"). The merger mechanics are as follows:
(a) Ardent Apex Holdings Inc. ("Apex Holdings"), a Delaware corporation incorporated on March 5, 2025, is the acquisition vehicle established for purposes of the Transaction. Apex Holdings is wholly owned by Ardent Capital Partners III LP.
(b) Ardent Apex Merger Sub Inc. ("Merger Sub"), a newly formed Delaware corporation incorporated on March 7, 2025, is a wholly owned direct subsidiary of Apex Holdings. Merger Sub was formed solely for the purpose of effecting the merger contemplated by the Transaction.
(c) Pursuant to the Agreement and Plan of Merger (described in Section 2.3 below), Merger Sub will merge with and into Luminex Systems Holdings Inc. (the "Merger"), with Luminex Holdings surviving the Merger as a wholly owned subsidiary of Apex Holdings.
(d) As a result of the Merger, the separate corporate existence of Merger Sub will cease, and Luminex Holdings will continue as the surviving corporation (the "Surviving Corporation"), with all of its assets, liabilities, and operations intact.
(e) Apex Holdings is, in turn, wholly owned by Ardent Capital Partners III LP. Accordingly, upon consummation of the Merger, Luminex Holdings will be an indirect wholly owned subsidiary of Ardent Capital Partners III LP.
The reverse triangular merger structure preserves Luminex Holdings' corporate existence, contractual relationships, governmental permits, and regulatory authorizations, including those held by its EU subsidiaries, which is of particular relevance for the continuity of operations in the European market.
2.2 Consideration and Valuation
The financial terms of the Transaction are as follows:
(a) Aggregate equity value: $2,800,000,000 (two billion eight hundred million United States dollars), payable in cash, except for management rollover equity of $405,020,000, as further described below.
(b) Per-share merger consideration: $20.00 per share, calculated on the basis of approximately 140,000,000 fully diluted shares of Luminex Holdings common stock (including vested and unvested options and restricted stock units, subject to customary adjustments).
(c) Enterprise value / revenue multiple: 5.75x, based on Luminex's consolidated revenue of $487,000,000 for the fiscal year ended December 31, 2024.
(d) Enterprise value / EBITDA multiple: 22.99x, based on Luminex's adjusted EBITDA of $121,800,000 for the fiscal year ended December 31, 2024.
The all-cash structure (with the exception of the management rollover) is relevant to the FSR analysis because the Transaction will not involve the issuance of equity securities on any EU-regulated market. Nevertheless, the sources and application of funds, including debt financing and co-investment commitments, are subject to detailed disclosure in the Form FS-CO, as discussed in Section 5.2 below.
2.3 Key Transaction Documents and Dates
The following key transaction documents have been executed or are in effect:
The Outside Date for consummation of the Merger is September 10, 2025, which is subject to automatic extension to December 10, 2025 in the event that the sole unsatisfied closing condition as of the initial Outside Date is the receipt of required regulatory approvals (including, without limitation, approvals under the HSR Act, CFIUS, the EU FSR, the German Act Against Restraints of Competition, and applicable Swiss regulatory processes). The estimated closing date, assuming timely receipt of all regulatory clearances, is Q3 2025 (July–August 2025).
2.4 Selling Shareholders
The current ownership of Luminex Holdings and the expected Transaction proceeds are as follows:
(a) Ridgeline Growth Equity Fund II LP (a Delaware limited partnership; 52% ownership of Luminex Holdings), headquartered at 200 Clarendon Street, 52nd Floor, Boston, MA 02116; Managing Partner: Jonathan Ashford. Expected proceeds: $1,456,000,000.
(b) Meridian Venture Partners IV LP (a Delaware limited partnership; 20% ownership of Luminex Holdings), headquartered at 600 Montgomery Street, Suite 2800, San Francisco, CA 94111; Managing Partner: Claire Fujimoto. Expected proceeds: $560,000,000.
(c) Management and employee shareholders (aggregate 28% ownership of Luminex Holdings), with aggregate consideration of $784,000,000, of which $405,020,000 will be in the form of rollover equity in Apex Holdings and $378,980,000 will be paid in cash. The principal management shareholders include:
(i) Dr. Stefan Kessler, Chief Executive Officer (8.5% ownership);
(ii) Annelise Gruber, Chief Financial Officer (4.2% ownership); and
(iii) Dr. Markus Vogt, Chief Technology Officer (3.8% ownership).
The management rollover equity arrangement is relevant to the FSR Notification to the extent it reflects the post-closing ownership structure and the alignment of management incentives, which may inform the Commission's assessment of the acquiring group's governance and control dynamics.
3. EU FSR Jurisdictional Thresholds Analysis
3.1 Applicable Legal Framework
The EU Foreign Subsidies Regulation — Regulation (EU) 2022/2560 of the European Parliament and of the Council of December 14, 2022, on foreign subsidies distorting the internal market — establishes a comprehensive framework for the European Commission to investigate and, where necessary, address distortive foreign subsidies affecting the EU's internal market. The Regulation has been in force since July 12, 2023, with the notification obligations for concentrations becoming effective on October 12, 2023.
Article 20 of the Regulation sets forth the mandatory notification thresholds applicable to concentrations, and Article 21 establishes the notification procedure. The notification must be submitted using Form FS-CO, as specified in Commission Implementing Regulation (EU) 2023/1441 of July 10, 2023, which lays down detailed rules on the form, content, and procedural aspects of notifications under the EU FSR.
We analyze each of the two jurisdictional thresholds below and provide our preliminary assessment. We request that Breitfeld Hess confirm and refine this analysis as part of the draft FSR Notification.
3.2 Threshold 1: EU Turnover of the Acquired Undertaking
Under Article 20(3)(a) of the Regulation, the first threshold requires that the acquired undertaking — that is, the Luminex group (Luminex Systems Holdings Inc. and all of its subsidiaries) — generated combined aggregate EU-wide turnover of at least €500,000,000 in the preceding financial year.
Luminex's principal operations are organized through the following entities, which are relevant to the EU turnover calculation:
(a) Luminex Systems GmbH (Leopoldstrasse 120, 80802 Munich, Germany; Commercial Register No. HRB 247891 at the Munich Local Court): Luminex's primary EU operating subsidiary, responsible for sales, customer support, implementation, and certain product development activities across the DACH region and broader European markets. Luminex Systems GmbH reported 2024 German-attributed revenue of approximately €67,000,000. This figure represents revenue booked through the German entity and does not capture the full scope of Luminex's EU revenues, which include direct sales from the parent entities to EU-domiciled customers.
(b) Luminex Systems AG (Bahnhofstrasse 71, 8001 Zürich, Switzerland; Commercial Register No. CHE-284.391.057): Luminex's original Swiss parent entity, which continues to serve as the operational headquarters for European commercial activities. We note that Switzerland is not a member of the European Union or the European Economic Area, and therefore Swiss-attributed revenue does not directly count toward the €500,000,000 EU turnover threshold. However, Luminex Systems AG may book revenue from EU-domiciled customers that should be allocated to the relevant EU member states for purposes of the threshold calculation.
(c) Luminex Systems UK Ltd. (14 Broadwick Street, London W1F 8HN, England; Companies House No. 12847362): Luminex's UK subsidiary, which principally serves UK-domiciled customers. Following the United Kingdom's withdrawal from the European Union, UK-attributed revenue is excluded from the EU turnover calculation. However, to the extent Luminex Systems UK Ltd. serves customers in EU member states (e.g., Ireland), those revenues should be allocated to the relevant member states.
Based on information available to us, Luminex's global revenue breakdown for fiscal year 2024 is approximately as follows:
We note that the DACH region encompasses Switzerland, which is not an EU member state. For purposes of the EU turnover threshold, it will be necessary to disaggregate Swiss revenue from German and Austrian revenue and to include revenue from Nordic EU member states (Sweden, Finland, Denmark) and any other EU member states (France, the Netherlands, Italy, etc.) served directly or indirectly by Luminex group entities.
Our preliminary estimate, based on Luminex's geographic revenue breakdown and an assumed EUR/USD exchange rate of approximately 1.08, is that the Luminex group's aggregate EU-wide turnover exceeds the €500,000,000 threshold when all EU member state revenues are properly aggregated across the entire Luminex group (including revenues booked by Luminex Systems AG, Luminex Systems GmbH, and Luminex Systems Holdings Inc. to EU-domiciled customers). However, this estimate requires verification against Luminex's audited financial statements.
Action Item for Breitfeld Hess: We request that Breitfeld Hess confirm the precise EU turnover allocation based on Luminex's audited consolidated financial statements for fiscal year 2024 (auditors: Hargrove Thornton LLP; Lead Audit Partner: Margaret Dawson), which are enclosed herewith as Enclosure 7. To the extent additional revenue allocation data is required from Luminex, we will coordinate with Luminex's counsel (Caldwell, Raines & Sheppard LLP) as described in Section 6.3 below.
3.3 Threshold 2: Foreign Financial Contributions
Under Article 20(3)(b) of the Regulation, the second threshold requires that at least two of the undertakings concerned — or, in the case of an acquisition of sole control, the acquiring undertaking and the acquired undertaking — received aggregate foreign financial contributions exceeding €50,000,000 from third countries in the three preceding calendar years (i.e., calendar years 2022, 2023, and 2024).
"Foreign financial contributions" are broadly defined under Article 3(2) of the Regulation and encompass, inter alia:
(a) transfers of funds or liabilities (such as capital injections, grants, loans, loan guarantees, fiscal incentives, the setting off of operating losses, compensation for financial burdens imposed by public authorities, debt forgiveness, debt-to-equity swaps, or reschedulings);
(b) the foregoing of revenue that is otherwise due (such as tax exemptions, preferential tax rulings, or the granting of special or exclusive rights without adequate remuneration); and
(c) the provision of goods or services, or the purchase of goods or services.
Critically, the definition of "third country" encompasses any country other than an EU member state, including the United States, Switzerland, Singapore, the United Kingdom, and any other jurisdiction in which the parties to the Transaction or their affiliates operate or from which they receive financial contributions.
We identify the following principal areas of potential foreign financial contributions:
A. Ardent Capital Partners III LP — Limited Partner Capital Commitments
Ardent Capital Partners III LP is a 2023 vintage fund with aggregate committed capital of approximately $12.5 billion. Ardent Capital Management LLC, the fund's investment manager, manages approximately $31.4 billion in aggregate assets under management across four flagship funds and co-investment vehicles. The fund's limited partner base includes sovereign wealth funds and state-affiliated pension funds from non-EU jurisdictions. To the extent capital commitments from these limited partners constitute "foreign financial contributions" within the meaning of Article 3(2) of the Regulation — an issue on which we request Breitfeld Hess's analysis — the aggregate amount of such contributions will substantially exceed the €50,000,000 threshold.
B. Co-Investors
The Transaction involves equity co-investments from two co-investors:
(i) Northvale Sovereign Holdings Ltd. (Cayman Islands exempted limited company; registered office: PO Box 309, Ugland House, George Town, Grand Cayman; contact: Ahmad Al-Rashid, Head of Direct Investments) — $200,000,000 co-investment commitment. Given the designation "Sovereign" in the entity name and the potential for state-affiliated ownership, we consider it likely that Northvale's co-investment will be characterized as a foreign financial contribution under the Regulation. We request Breitfeld Hess's detailed analysis on this point, including whether the co-investment constitutes a contribution "by a third country" or an entity that is "directly or indirectly attributable to a third country" within the meaning of Article 3(2).
(ii) Summit Ridge Capital Partners LP (161 North Clark Street, Suite 4700, Chicago, IL 60601; contact: Karen Lindstrom) — $100,000,000 co-investment commitment. Summit Ridge appears to be a private capital fund without apparent sovereign affiliation, but its limited partner base should be verified for any state-affiliated investors.
C. Government Subsidies, Grants, Tax Incentives, and Preferential Financing
Both the Ardent Capital group (including portfolio companies) and the Luminex group may have received foreign financial contributions in the form of government subsidies, grants, tax credits, economic development incentives, or preferential tax rulings during the three-year lookback period. In particular:
(i) Ardent Capital's portfolio companies, including Vectis Solutions LLC (4000 Shoreline Court, Suite 300, South San Francisco, CA 94080; CEO: Michael Parekh; EIN: 82-4910337), may have received U.S. federal or state government grants, subsidies, R&D tax credits, or other financial contributions.
(ii) Luminex group entities may have received Swiss cantonal or federal tax rulings benefiting Luminex Systems AG, Singapore tax incentives benefiting Luminex Systems Pte. Ltd. (including potential pioneer industry or development and expansion incentives administered by the Singapore Economic Development Board), and U.S. federal or state economic development incentives benefiting Luminex Systems Holdings Inc.
D. Aggregate Assessment
Based on the foregoing, we are confident that the aggregate foreign financial contributions received by the undertakings concerned during calendar years 2022, 2023, and 2024 will exceed the €50,000,000 threshold, triggered principally by the sovereign wealth fund and state-affiliated limited partner capital commitments in Ardent Capital Partners III LP and the Northvale Sovereign Holdings Ltd. co-investment.
Action Item for Breitfeld Hess: We instruct Breitfeld Hess to compile a detailed inventory of all foreign financial contributions (as defined under Article 3(2) of the Regulation) received by Ardent Capital Partners III LP, Ardent Apex Holdings Inc., the co-investors (Northvale Sovereign Holdings Ltd. and Summit Ridge Capital Partners LP), and their respective controlled entities during calendar years 2022, 2023, and 2024. This inventory should include, for each identified contribution:
(a) capital commitments and drawdowns from non-EU sovereign wealth and state-affiliated limited partners in Ardent Capital Partners III LP and predecessor funds;
(b) any government subsidies, grants, tax incentives, R&D credits, or preferential financing received by Ardent Capital's portfolio companies (including, without limitation, Vectis Solutions LLC and Vectis GmbH);
(c) financial contributions from non-EU state entities to co-investors, with particular focus on Northvale Sovereign Holdings Ltd. and its ultimate beneficial ownership and state affiliations; and
(d) any other transfers, forgone revenues, or goods/services transactions falling within the broad definition of Article 3(2).
3.4 Conclusion on Jurisdictional Thresholds
Based on our preliminary analysis, both jurisdictional thresholds under Article 20(3) of the Regulation are expected to be satisfied. Accordingly, the Transaction is subject to mandatory notification to the European Commission under Article 21 of the Regulation, and the Transaction may not be consummated prior to the Commission's clearance decision or the expiry of the applicable review periods. We request that Breitfeld Hess confirm this jurisdictional assessment in the draft FSR Notification.
4. Parties to the Notification
4.1 Notifying Party
The notifying party for purposes of the FSR Notification is:
Ardent Apex Holdings Inc. A Delaware corporation Employer Identification Number (EIN): 93-2178435 Date of Incorporation: March 5, 2025 Registered Agent: National Registered Agents of Delaware, Inc., 160 Greentree Drive, Suite 101, Dover, DE 19904
Apex Holdings is acting as the direct acquisition vehicle for the Transaction and will be the entity that, following consummation of the Merger, directly holds 100% of the equity of the Surviving Corporation (Luminex Systems Holdings Inc.).
Apex Holdings is in turn wholly owned by its ultimate parent:
Ardent Capital Partners III LP A Delaware limited partnership Employer Identification Number (EIN): 87-3941026 Principal Office: 399 Park Avenue, 42nd Floor, New York, NY 10022 General Partner: Ardent Capital GP III LLC (a Delaware limited liability company) Managing Partners: Theodore "Ted" Hargrove and Victoria Langford
For purposes of Form FS-CO, the notifying party should be identified as Ardent Apex Holdings Inc., acting through its ultimate parent entity Ardent Capital Partners III LP. The full organizational structure of the Ardent Capital group, including all fund vehicles, general partner entities, Apex Holdings, and Merger Sub, is set forth in the organizational chart enclosed as Enclosure 2.
4.2 Target Undertaking
The target undertaking is:
Luminex Systems Holdings Inc. A Delaware corporation Employer Identification Number (EIN): 86-2547193 Date of Incorporation: June 14, 2021 Registered Agent: Capitol Corporate Services, Inc., 1675 South Ashbury Asset Advisors, Suite B, Dover, DE 19901 Operational Headquarters: 2100 Reston Gateway Drive, Suite 800, Reston, VA 20191
We note that Luminex Systems Holdings Inc. was created in 2021 as part of a corporate reorganization in which the legacy Swiss parent entity, Luminex Systems AG (Swiss Aktiengesellschaft; Commercial Register No. CHE-284.391.057), established a U.S. holding company structure. As a result of that reorganization, Luminex Systems Holdings Inc. is the ultimate parent of the Luminex group for purposes of this Transaction, notwithstanding that Luminex Systems AG historically served — and in operational terms continues to serve — as the center of European commercial activities.
The key EU subsidiaries of the Luminex group to be identified in the Form FS-CO are:
(a) Luminex Systems GmbH (Leopoldstrasse 120, 80802 Munich, Germany; Commercial Register No. HRB 247891 at the Munich Local Court) — the principal EU operating subsidiary.
(b) Luminex's EU customer base extends beyond Germany to include Austria and the DACH region, Nordic EU member states (Sweden, Denmark, Finland), and additional EU markets served through direct sales and distribution arrangements.
For completeness, the following non-EU subsidiaries should also be disclosed in the organizational chart accompanying the notification:
(c) Luminex Systems AG (Bahnhofstrasse 71, 8001 Zürich, Switzerland; Commercial Register No. CHE-284.391.057) — Swiss entity.
(d) Luminex Systems UK Ltd. (14 Broadwick Street, London W1F 8HN, England; Companies House No. 12847362) — UK entity.
(e) Luminex Systems Pte. Ltd. (Singapore; Unique Entity Number 201924781K) — Singapore entity.
4.3 Seller Entities (for Informational Disclosure)
While the selling shareholders are not notifying parties, they should be identified in the Form FS-CO for informational purposes in accordance with the Commission's guidance:
(a) Ridgeline Growth Equity Fund II LP (52% ownership of Luminex Holdings);
(b) Meridian Venture Partners IV LP (20% ownership of Luminex Holdings); and
(c) Management and employee shareholders (28% ownership of Luminex Holdings), as detailed in Section 2.4 above.
5. Scope of Information Required for Form FS-CO
We set forth below the principal categories of information required for Form FS-CO and our guidance on the content to be included in each section. Breitfeld Hess should use this as a framework for preparing the draft notification, supplemented by the Commission's Implementing Regulation and any informal guidance received through pre-notification contacts with the Commission's FSR Unit.
5.1 Section A — General Information
Section A of Form FS-CO requires comprehensive identification of the parties and their corporate structures. The following should be included:
(a) Corporate structure charts for both the Ardent Capital group and the Luminex group. For the Ardent Capital group, the chart should include all fund vehicles (Ardent Capital Partners I LP through Ardent Capital Partners III LP and associated co-investment vehicles), the general partner and management entities (Ardent Capital GP III LLC, Ardent Capital Management LLC), Ardent Apex Holdings Inc., and Ardent Apex Merger Sub Inc. For the Luminex group, the chart should include Luminex Systems Holdings Inc. (U.S. parent), Luminex Systems AG (Swiss entity), Luminex Systems GmbH (German subsidiary), Luminex Systems UK Ltd. (UK subsidiary), and Luminex Systems Pte. Ltd. (Singapore subsidiary). Organizational charts for both groups are enclosed as Enclosure 2.
(b) Identification of all controlled undertakings with EU activities. In addition to Luminex Systems GmbH, which is the principal EU operating entity of the Luminex group, the notification should identify Vectis Solutions LLC (4000 Shoreline Court, Suite 300, South San Francisco, CA 94080; CEO: Michael Parekh; EIN: 82-4910337) as a portfolio company of the Ardent Capital group (acquired through Ardent Capital Partners II LP). Vectis Solutions LLC operates a German subsidiary, Vectis GmbH, which reported 2024 German-attributed revenue of approximately €12,000,000. Vectis GmbH's EU activities must be disclosed as part of the Ardent Capital group's EU footprint.
(c) Contact details, legal representatives, and authorized agents for all parties.
5.2 Section B — Description of the Concentration
Section B requires a detailed description of the concentration, including the legal structure, economic rationale, financing arrangements, and timetable. The following content should be included:
Transaction Structure: The notification should describe the reverse triangular merger mechanics under the DGCL, as summarized in Section 2.1 above, with particular attention to the resulting control structure (Ardent Capital Partners III LP → Ardent Apex Holdings Inc. → Luminex Systems Holdings Inc. (as Surviving Corporation) → all Luminex subsidiaries).
Sources and Uses: The notification should include a detailed sources and uses summary, which we set forth below:
Sources of Funds:
Uses of Funds:
We note that the modest difference between total sources and total uses reflects rounding and estimates for transaction expenses and financing fees, which are subject to final adjustment at closing. Breitfeld Hess should present the sources and uses in a manner consistent with the requirements of Form FS-CO and reconcile any differences in the final draft.
Financing Structure: The notification should describe in detail the financing arrangements for the Transaction:
(a) Senior Secured Credit Facility: Aggregate commitments of $1,400,000,000, consisting of:
(i) Term Loan B: $1,200,000,000 at a floating rate of SOFR plus 475 basis points, with a seven-year maturity; and
(ii) Revolving Credit Facility: $200,000,000 at a floating rate of SOFR plus 425 basis points, with a five-year maturity.
Administrative Agent and lead arranger: Stonebridge Credit Partners LLC. Co-lenders include Birchwood Capital Finance LLC ($350,000,000 hold amount) and Ironvale Credit Fund III LP ($250,000,000 hold amount). The commitment letter is enclosed as Enclosure 3 (Ref. SC-2025-0312-AC, dated March 8, 2025).
(b) Subordinated Notes: $300,000,000 principal amount of subordinated notes to be issued to Crestline Mezzanine Partners II LP, bearing interest at 11.5% per annum (PIK toggle), with an eight-year maturity and 2.0% warrant coverage on the equity of Ardent Apex Holdings Inc. The Subordinated Note Purchase Agreement is enclosed as Enclosure 6.
Assessment of Debt Financing as Foreign Financial Contributions: A critical question for the FSR Notification is whether the debt financing constitutes, in whole or in part, a "foreign financial contribution" under Article 3(2) of the Regulation. While arm's-length commercial lending by private financial institutions would not ordinarily constitute a foreign financial contribution, the analysis may differ if any of the lending institutions — Stonebridge Credit Partners LLC, Birchwood Capital Finance LLC, or Ironvale Credit Fund III LP — have themselves received state support from non-EU third-country governments that could be attributed to their lending activities. We request that Breitfeld Hess analyze this issue and advise on the appropriate disclosure in the Form FS-CO.
5.3 Section C — Foreign Financial Contributions
Section C is the critical section of the Form FS-CO and will require the most substantial analytical effort from Breitfeld Hess. This section must contain a detailed inventory of all foreign financial contributions within the meaning of Article 3(2) of the Regulation, covering the three-year lookback period (calendar years 2022, 2023, and 2024).
The inventory should be organized by the following categories:
(i) Direct financial contributions from third-country governments or public entities to Ardent Capital and its affiliates. This includes any grants, subsidies, loan guarantees, preferential financing, tax credits, or other financial transfers received directly by Ardent Capital Partners III LP, Ardent Capital GP III LLC, Ardent Capital Management LLC, Ardent Apex Holdings Inc., or any of Ardent Capital's controlled portfolio companies from governments of non-EU countries, including federal, state, and local government entities in the United States, as well as government entities in any other jurisdiction in which Ardent Capital or its portfolio companies operate.
(ii) Financial contributions channeled through sovereign wealth fund and state-affiliated pension fund limited partners. Capital commitments and drawdowns from limited partners in Ardent Capital Partners III LP (and, to the extent relevant, predecessor funds) that are sovereign wealth funds, state-owned investment vehicles, or state-affiliated pension funds. The Commission has indicated that capital contributions from entities that are directly or indirectly attributable to a third-country government may constitute foreign financial contributions for purposes of the Regulation. We request Breitfeld Hess's analysis on the treatment of passive limited partner capital commitments in this context, including any relevant Commission guidance or decisional practice.
(iii) Financial contributions to Northvale Sovereign Holdings Ltd. As noted in Section 3.3 above, Northvale Sovereign Holdings Ltd. is a Cayman Islands exempted limited company with a co-investment commitment of $200,000,000. Given the entity's apparent sovereign affiliations, the Commission is likely to scrutinize the source of Northvale's capital. The notification should disclose Northvale's ownership structure, any government affiliations, and the nature and source of the funds committed to the co-investment. We are separately requesting this information from Ahmad Al-Rashid, as described in Section 6.2 below.
(iv) Subsidies, tax credits, grants, or preferential loans received by Luminex group entities from non-EU third countries. This category includes, without limitation:
• U.S. federal or state economic development incentives received by Luminex Systems Holdings Inc. or its U.S. operations (including any grants, tax abatements, or workforce development incentives related to the Reston, Virginia headquarters);
• Swiss cantonal or federal tax rulings benefiting Luminex Systems AG (including any special tax arrangements under the applicable cantonal tax regime in Zürich);
• Singapore tax incentives benefiting Luminex Systems Pte. Ltd. (including any pioneer industry incentives, development and expansion incentives, or other preferential tax treatments administered by the Inland Revenue Authority of Singapore or the Singapore Economic Development Board); and
• Any research and development tax credits or innovation grants received by Luminex group entities in any non-EU jurisdiction.
(v) Financial contributions to Vectis Solutions LLC or its subsidiaries. As an Ardent Capital portfolio company with EU activities (through Vectis GmbH in Germany), any foreign financial contributions received by Vectis Solutions LLC or its controlled entities must be disclosed. This includes U.S. federal or state R&D tax credits, Small Business Innovation Research ("SBIR") grants, or other government funding.
For each identified foreign financial contribution, the notification must include:
• the amount of the contribution;
• the identity of the granting authority (including the country and level of government);
• the date or dates of the contribution;
• the legal basis for the contribution;
• a description of the nature and purpose of the contribution; and
• an assessment of whether the contribution constitutes a "subsidy" within the meaning of Article 3(1) of the Regulation (i.e., a financial contribution that confers a benefit on an undertaking).
The three-year lookback period covers calendar years 2022, 2023, and 2024. Breitfeld Hess should apply the aggregation methodology set forth in the Commission's guidance documents and the Implementing Regulation, including the applicable de minimis thresholds and the methodology for attributing contributions to the undertakings concerned.
5.4 Section D — Internal Market Effects
Section D of Form FS-CO requires an analysis of whether any identified foreign financial contribution has or could have distortive effects on the EU internal market in connection with the concentration. The analysis should address the following:
Relevant Product Market: The primary product market relevant to the Transaction is enterprise SaaS, and more specifically, procurement-automation SaaS and enterprise resource planning ("ERP") platforms. Luminex's flagship product, the "Luminex One" platform, is a cloud-based procurement-automation solution that enables enterprise customers to manage sourcing, supplier relationship management, contract lifecycle management, and spend analytics. The platform competes with products offered by Ostrander Industries, Pemberton & Co. (now Ostrander Equity Partners), Meridian Corporation, Halcyon Holdings, and other providers in the enterprise procurement technology space.
Geographic Market: The relevant geographic market for purposes of the FSR analysis is at least EU-wide, and potentially broader (EEA-wide or global), depending on the Commission's market definition. Luminex serves EU customers across the DACH region (approximately 35% of global revenue, excluding Switzerland), the Nordics, and other EU member states.
Competitive Landscape and Combined Market Shares: The FSR Notification should include an assessment of the competitive dynamics in the relevant market, with particular attention to the combined position of Luminex and Vectis Solutions LLC (an Ardent Capital portfolio company that also operates in the procurement-automation SaaS space). Based on available market data:
• Luminex holds an estimated ~18% share of the EU procurement-automation SaaS market;
• Vectis Solutions LLC holds an estimated ~7% share of the EU procurement-automation SaaS market; and
• The combined post-Transaction share would be approximately ~25% of the EU procurement-automation SaaS market.
These market share figures should be consistently presented across the FSR Notification, the Bundeskartellamt filing, and the HSR notification, and we request Breitfeld Hess to coordinate with Wendt Schäfer Rechtsanwälte PartG mbB and Elaine Forsythe's team to ensure alignment.
Assessment of Distortive Effects: It is our preliminary assessment that the Transaction is unlikely to result in distortive effects from foreign subsidies within the meaning of the Regulation. The principal foreign financial contributions identified in the analysis — limited partner capital commitments from sovereign wealth and state-affiliated pension funds — represent passive financial investments made on commercial terms and do not constitute targeted subsidies designed to distort competition in the EU procurement-automation SaaS market. The Commission's guidance distinguishes between foreign financial contributions that are commercial in nature and those that constitute state aid–like distortive subsidies, and we believe the former characterization applies here.
Nevertheless, the notification should address the Commission's potential concerns comprehensively and in good faith, and should include a robust analysis demonstrating the absence of distortive effects. We request Breitfeld Hess to develop this analysis, potentially with the assistance of an external economic consultant if the Commission indicates that a quantitative assessment would be expected.
5.5 Section E — Commitments (if applicable)
At this stage, we do not anticipate that Ardent Capital will offer any commitments or remedial measures in connection with the FSR Notification. However, we request that Breitfeld Hess advise on:
(a) the types of remedial measures or commitments the Commission could request if it determines that the Transaction raises concerns regarding distortive foreign subsidies and opens an in-depth investigation under Article 25 of the Regulation;
(b) any precedents from the Commission's early decisional practice under the FSR that may be informative regarding the scope and nature of potential commitments; and
(c) the procedural framework for offering commitments, including the applicable deadlines and the interaction between commitments offered during the preliminary review period and those offered during an in-depth investigation.
This analysis should be provided in the form of a separate advisory memorandum to Calderwood & Harkness, rather than included in the FSR Notification itself.
6. Information Gathering and Document Requests
The preparation of the FSR Notification will require the collection of substantial information and documents from multiple parties. We outline below the information requests that are being made to each relevant party, and the role of Breitfeld Hess in processing and incorporating this information into the notification.
6.1 From Ardent Capital
Calderwood & Harkness will coordinate directly with Ardent Capital Partners III LP to obtain the following information and documents. The principal contacts at Ardent Capital are Theodore "Ted" Hargrove (Managing Partner), Victoria Langford (Managing Partner), and David Ng (Chief Financial Officer). We expect to transmit the relevant materials to Breitfeld Hess promptly upon receipt.
(a) Fund formation documents for Ardent Capital Partners III LP and predecessor funds (Ardent Capital Partners I LP and Ardent Capital Partners II LP), including the limited partnership agreement, subscription documents, and side letter agreements, to the extent relevant for identifying sovereign wealth and state-affiliated limited partners.

6.2 From Co-Investors
We are separately requesting information from the Transaction's co-investors, and we ask Breitfeld Hess to follow up directly with these parties' counsel to the extent necessary for the FSR Notification:
(a) Northvale Sovereign Holdings Ltd.: We are requesting that Ahmad Al-Rashid, Head of Direct Investments, provide comprehensive details regarding Northvale's ownership structure, its direct and indirect affiliations with any government or state-owned entity, and any financial contributions received from third-country public entities during the lookback period. Given the significance of Northvale's co-investment for the FSR analysis, this information is critical and should be obtained as promptly as possible.
(b) Summit Ridge Capital Partners LP: We are requesting that Karen Lindstrom provide similar disclosure regarding Summit Ridge's ownership structure, any government affiliations, and the composition of its limited partner base, with particular attention to any sovereign wealth or state-affiliated investors.
6.3 From Luminex (via Seller's Counsel)
Information regarding foreign financial contributions received by the Luminex group will be obtained through Luminex's legal counsel, Caldwell, Raines & Sheppard LLP (contacts: Patricia Okonkwo, Partner, and Daniel Feinberg, Associate). Calderwood & Harkness will submit the information request to Caldwell Raines under the terms of the cooperation covenant in the Merger Agreement. We request the following:
(a) Details of any non-EU government subsidies, grants, tax incentives, or other financial contributions received by any Luminex group entity during calendar years 2022, 2023, and 2024.
(b) Specific information regarding Singapore tax incentives for Luminex Systems Pte. Ltd. (UEN 201924781K), including any pioneer industry incentives, development and expansion incentives, or other preferential tax treatments, with the amounts, granting authorities, legal bases, and dates of each incentive.
(c) Details of any Swiss cantonal or federal tax rulings applicable to Luminex Systems AG (CHE-284.391.057), including any advance rulings or agreements with the Zürich cantonal tax authorities providing for a reduced effective tax rate, and the estimated annual benefit of such rulings during the lookback period.
(d) U.S. federal or state economic development incentives received by Luminex Systems Holdings Inc. or any U.S.-based Luminex entity, including any Virginia-based incentive programs, R&D tax credits, or workforce development grants.
(e) A revenue breakdown by EU member state for each of the three preceding fiscal years (2022, 2023, and 2024), in sufficient detail to calculate the aggregate EU turnover of the Luminex group for purposes of the Threshold 1 analysis in Section 3.2 above.
6.4 From Vectis Solutions LLC
As an Ardent Capital portfolio company with EU activities, Vectis Solutions LLC must be included in the foreign financial contributions inventory. We are requesting the following information from Michael Parekh (CEO, Vectis Solutions LLC):
(a) Details of any government grants, subsidies, R&D tax credits, SBIR grants, or other financial contributions received by Vectis Solutions LLC or any of its subsidiaries (including Vectis GmbH in Germany) during calendar years 2022, 2023, and 2024.

7. Timeline and Review Periods
7.1 Filing Timeline
The target filing date for the FSR Notification is April 11, 2025. This date has been previously discussed between our respective teams and is now confirmed. Given the compressed timeline — three business days from the date of this letter — we emphasize the importance of prioritizing the preparation of the draft Form FS-CO and request that Breitfeld Hess allocate the necessary resources to ensure timely completion.
We request that Breitfeld Hess confirm whether pre-notification contacts with the European Commission's DG Competition, FSR Unit, have been initiated or are advisable in advance of the April 11 filing date. Pre-notification discussions can be valuable in ensuring that the Commission considers the notification substantially complete upon receipt, thereby accelerating the commencement of the formal review period. If pre-notification contacts have not yet been initiated, please advise on the feasibility and desirability of an informal approach to the FSR Unit prior to filing.
7.2 Review Periods Under the FSR
The Commission's review of the FSR Notification will proceed according to the following statutory timetable:
(a) Preliminary review period: 25 business days from the date the notification is deemed complete by the Commission (Article 24(1) of the Regulation). Assuming the notification is deemed complete promptly after the April 11 filing, the preliminary review period would expire approximately mid-May 2025. During this period, the Commission will assess whether the Transaction raises prima facie concerns regarding distortive foreign subsidies.
