I. Executive Summary
The purpose of this memorandum is to analyze the scope and practical implications of the intellectual property transfer restrictions contained in the executed National Security Agreement, designated NSA-2024-0019 and dated January 19, 2024 (the "NSA"), on the ability of Halcyon Semiconductor Aktiengesellschaft ("HSAG") to leverage the intellectual property portfolio of Marlowe Asset Management Photonics Inc. ("VPI") following the closing of HSAG's acquisition of VPI, which is currently targeted for February 9, 2024. This memorandum is being circulated promptly following execution of the NSA to ensure that HSAG and its advisors have a comprehensive understanding of the operative restrictions before closing occurs and before any post-closing integration activities are initiated.
The NSA was executed among four parties: (i) Halcyon Semiconductor Aktiengesellschaft, a German stock corporation (Aktiengesellschaft) organized under the laws of the Federal Republic of Germany; (ii) Halcyon US Holdings Inc., a Delaware C-corporation formed on June 5, 2023, as the acquisition vehicle for the transaction; (iii) Marlowe Asset Management Photonics Inc., a Delaware C-corporation incorporated on February 14, 2009, the target company; and (iv) the United States of America, acting through the Department of the Treasury, the Department of Defense, and the Department of Energy, each in its capacity as a CFIUS monitoring agency. The NSA imposes significant and, in certain cases, severe constraints on the transfer of intellectual property from VPI to HSAG and its affiliates, as well as on cross-border research and development collaboration between VPI and HSAG's non-U.S. operations.
Key Conclusion. HSAG will face material restrictions on integrating VPI technology into its commercial semiconductor product lines. These restrictions are most acute with respect to: (a) ITAR-controlled defense articles falling within Category XI(a)(3) of the United States Munitions List; (b) items classified under Export Administration Regulations ECCNs 3A001, 3A991, and 3E001; and (c) government-funded inventions subject to Bayh-Dole Act march-in rights under 35 U.S.C. § 203. The restrictions are compounding in nature — they interact with, and are reinforced by, the Technology Control Plan set forth in NSA Annex B (the "TCP"), the cybersecurity and data segregation requirements set forth in NSA Annex D (implementing NIST Special Publication 800-171), and the governance structures established through the Government Security Committee under NSA Annex C.
The IP transfer restrictions established by the NSA can be organized into five categories of impact, ranging from most restrictive to least restrictive:
(a) Complete Prohibition on Transfer. Classified information and classified IP developed under VPI's SECRET-level defense contracts are subject to an absolute prohibition on transfer to any HSAG personnel, regardless of nationality or location. HSAG board designees are also barred from access.
(b) Transfers Requiring Prior U.S. Government Authorization. ITAR-controlled unclassified technical data and EAR-controlled dual-use technology may not be transferred to non-U.S. persons — including HSAG parent company personnel and HSAG affiliates worldwide — without prior written authorization from the Department of State's Directorate of Defense Trade Controls ("DDTC") or the Department of Commerce's Bureau of Industry and Security ("BIS"), as applicable.
(c) Transfers Requiring Government Security Committee Approval. Government program proprietary information that is not export-controlled but is designated as sensitive under the TCP requires prior approval from the Government Security Committee ("GSC") before any transfer to HSAG entities.
(d) Transfers Permissible Under Defined Protocols. A limited subset of VPI's commercial and non-controlled intellectual property may be shared with HSAG, provided that TCP classification procedures are completed and all data flows through the approved information gateway between VPI and HSAG IT systems.
(e) Compliance Enforcement. Violations of the NSA's IP transfer restrictions may result in civil penalties of up to $250,000 per violation per day under NSA Section 12.3, injunctive relief sought by the U.S. government, or — in the case of material or repeated violations — mandated divestiture of VPI by HSAG. These penalties are in addition to any sanctions that may be imposed under ITAR or EAR for unauthorized exports.
Ongoing compliance monitoring will be conducted by Whitmore Compliance Group LLC (principal: Gerald Whitmore, former Deputy Assistant Director, Counterintelligence Division, Federal Bureau of Investigation), which has been designated as the third-party monitor under NSA Section 11. The monitor will conduct annual compliance audits and report directly to CFIUS monitoring agencies, including the Defense Counterintelligence and Security Agency ("DCSA"), the Department of the Treasury, the Department of Defense, and the Department of Energy. The cost of the third-party monitor is $1.2 million per annum, payable quarterly in installments of $300,000, and is borne exclusively by HSAG, subject to annual adjustment based on the Consumer Price Index.
This memorandum should be read in conjunction with the following related memoranda previously circulated or under preparation by this firm: (i) VPI Patent Portfolio Summary & Valuation Considerations; (ii) Government Rights in Subject Inventions Memo; (iii) Trade Secret Protection Assessment; (iv) ITAR/EAR Classification Review Memorandum; and (v) NSA Summary & Compliance Obligations Memo to Client.
II. Background
A. Transaction Overview
On June 10, 2023, HSAG executed a Stock Purchase Agreement (the "SPA") to acquire 100% of the outstanding equity of VPI. The transaction structure and principal commercial terms are as follows:
Acquirer. Halcyon Semiconductor Aktiengesellschaft, a publicly traded stock corporation (Aktiengesellschaft) listed on the Frankfurt Stock Exchange (XETRA: HLC), with a market capitalization of approximately €14.8 billion as of June 1, 2023. HSAG is headquartered at Industriestraße 44, 01099 Dresden, Saxony, Federal Republic of Germany. The company is led by Chief Executive Officer Dr. Maximilian Ehrhardt and reported fiscal year 2022 revenue of €6.12 billion and EBITDA of €1.37 billion. HSAG is a global semiconductor company with significant operations in Europe, the United States, and Asia, including design centers, wafer fabrication facilities, and assembly and test operations in multiple jurisdictions.
Acquisition Vehicle. Halcyon US Holdings Inc., a Delaware C-corporation formed on June 5, 2023, specifically for the purpose of this acquisition. Halcyon US Holdings Inc. is a wholly owned subsidiary of HSAG and will serve as the direct parent of VPI following the closing.
HSAG's Existing U.S. Operations. Prior to this acquisition, HSAG maintained U.S. operations through Halcyon US Inc., a fabless semiconductor design center located at 11501 Alterra Parkway, Suite 300, Austin, Texas 78758. Halcyon US Inc. employs approximately 320 engineers and support staff and does not hold a facility security clearance or engage in any classified work for the U.S. government. Halcyon US Inc.'s primary activities involve the design of power management integrated circuits and radio frequency front-end modules for commercial applications.
Target. Marlowe Asset Management Photonics Inc., a Delaware C-corporation incorporated on February 14, 2009, headquartered at 7400 Ridgeline Parkway, Colorado Springs, Colorado 80919. VPI operates a wafer fabrication facility at 9200 Innovation Boulevard, Albuquerque, New Mexico 87113, consisting of a 45,000-square-foot gallium nitride on silicon carbide (GaN-on-SiC) fabrication facility. The Albuquerque facility maintains a Facility Security Clearance at the SECRET level, with CAGE Code 7VK92. VPI is led by Chief Executive Officer Dr. Nathan Trevorrow and reported fiscal year 2022 revenue of $287.4 million and EBITDA of $61.2 million. VPI employs 486 individuals, of whom 212 hold active U.S. government security clearances at the SECRET level or above — representing approximately 43.6% of the workforce.
Purchase Price. The aggregate consideration for the transaction is $1.42 billion on a cash-free, debt-free basis, with a net working capital target of $34.6 million, subject to customary post-closing adjustments. In addition, HSAG has agreed to an earnout of up to $85 million, consisting of $50 million payable upon achievement of calendar year 2024 revenue targets and $35 million payable upon achievement of calendar year 2025 revenue targets, each as defined in the SPA. The maximum aggregate consideration payable by HSAG is therefore $1.505 billion.
Closing. Closing of the transaction is currently targeted for February 9, 2024, subject to satisfaction of all remaining closing conditions, including effectiveness of the NSA and receipt of the CFIUS safe-harbor letter.
B. VPI intellectual Property Portfolio Summary
VPI's intellectual property portfolio is central to the strategic rationale for this transaction and is the subject of the NSA restrictions analyzed in this memorandum. The portfolio consists of the following:
Patents. VPI holds 47 granted United States patents and has 12 patent applications pending before the United States Patent and Trademark Office. The granted patents are concentrated in three principal patent families:
(i) GaN-on-SiC Epitaxial Growth Process. This family comprises 8 patents (U.S. Patent Nos. 9,XXX,001 through 9,XXX,008) with the earliest priority date in 2012. These patents cover VPI's proprietary processes for growing high-quality gallium nitride epitaxial layers on silicon carbide substrates, which form the foundation of VPI's GaN power amplifier manufacturing capability. The patented processes address nucleation layer control, buffer layer engineering, and defect density optimization.
(ii) HEMT Gate Structure Optimization. This family comprises 19 patents (U.S. Patent Nos. 10,XXX,101 through 10,XXX,119) with the earliest priority date in 2015. These patents cover VPI's innovations in high electron mobility transistor (HEMT) gate structures, including field plate geometries, gate recess engineering, and passivation techniques that improve power density, thermal management, and reliability at high frequencies. Several patents in this family incorporate classified subject matter and are the subject of secrecy orders.
(iii) mmWave Broadband Matching Network. This family comprises 20 patents (U.S. Patent Nos. 11,XXX,201 through 11,XXX,220) with the earliest priority date in 2018. These patents cover VPI's proprietary designs for broadband impedance matching networks operating in the millimeter-wave (mmWave) frequency bands, which enable wideband GaN power amplifier modules for radar, electronic warfare, satellite communications, and 5G applications. As with the HEMT gate structure family, certain patents in this family are associated with classified programs.
Trade Secrets. VPI maintains 31 formally registered internal trade secrets, identified and catalogued pursuant to VPI's Trade Secret Management Program. These trade secrets primarily encompass: (a) proprietary GaN epitaxial growth recipes, including specific temperature profiles, gas flow ratios, and timing sequences used in metalorganic chemical vapor deposition (MOCVD) processes; and (b) die-level reliability screening processes, including burn-in protocols, parametric screening criteria, and accelerated life test methodologies developed to meet stringent military specification requirements.
Government-Funded IP. Of VPI's 47 granted U.S. patents, 23 were developed in whole or in part under U.S. government-funded contracts. These patents constitute "subject inventions" within the meaning of the Bayh-Dole Act (35 U.S.C. §§ 200–212) and are subject to the government's retained rights, including a nonexclusive, nontransferable, irrevocable, paid-up license to practice each invention, as well as the government's march-in rights under 35 U.S.C. § 203. Additional disclosure and reporting obligations are imposed under DFARS 252.227-7038 (Patent Rights — Ownership by the Contractor (Large Business)).
Export-Controlled Products and Technology. VPI's products and technical data include items classified as ITAR Category XI(a)(3) defense articles under the United States Munitions List, as well as items classified under EAR ECCNs 3A001 (certain microwave or millimeter-wave integrated circuits), 3A991 (electronic devices not controlled by 3A001), and 3E001 (technology for the development or production of commodities controlled by 3A001). VPI is registered with the Directorate of Defense Trade Controls under Registration No. M-24817.
C. CFIUS Process and NSA Context
The CFIUS review and NSA negotiation process proceeded as follows:
HSAG and VPI filed a voluntary joint notice with CFIUS on July 14, 2023, pursuant to Section 721 of the Defense Production Act of 1950, as amended (50 U.S.C. § 4565), and 31 C.F.R. Part 800. The filing was assigned CFIUS Case No. CFIUS-023-07-3841. CFIUS accepted the joint notice and commenced its initial 45-day review period on July 21, 2023. Upon expiration of the initial review period, CFIUS initiated a 45-day investigation on September 4, 2023, reflecting the complexity of the national security issues presented by the transaction.
On October 20, 2023, CFIUS communicated to the parties four preliminary national security concerns. While the full substance of these communications is addressed in our separate NSA Summary & Compliance Obligations Memo, the concerns included, most relevantly for present purposes, a specific concern regarding the potential transfer of ITAR-controlled and EAR-controlled technology from VPI to non-U.S. persons associated with HSAG's German parent company and its global affiliates. CFIUS identified the risk that VPI's advanced GaN semiconductor technology — developed under classified and unclassified U.S. government contracts — could be transferred, directly or indirectly, to foreign persons or entities in a manner that would undermine U.S. national security interests, compromise the integrity of U.S. defense supply chains, or provide adversary nations with access to critical technologies.
Following identification of these concerns, the parties entered into NSA negotiations with CFIUS and the relevant monitoring agencies from November 9, 2023, through December 15, 2023. These negotiations involved extensive discussions regarding the scope of technology transfer restrictions, the structure and composition of the Government Security Committee, the requirements of the Technology Control Plan, cybersecurity and data segregation mandates, personnel continuity requirements, and the appointment and authority of the third-party monitor. The final NSA was executed on January 19, 2024, and a safe-harbor letter was issued by CFIUS on January 26, 2024, confirming that CFIUS has concluded all action with respect to the transaction.
For purposes of the Foreign Ownership, Control, or Influence ("FOCI") mitigation framework administered by DCSA under the National Industrial Security Program Operating Manual (NISPOM), the NSA functions as a Security Supervision Agreement ("SSA")-equivalent, governing HSAG's oversight of VPI while preserving VPI's facility security clearance and ability to perform classified work for the U.S. government.
D. HSAG's Planned Technology Integration Objectives
Understanding HSAG's strategic rationale for the VPI acquisition and its planned post-closing integration activities is essential context for assessing the practical impact of the NSA's IP transfer restrictions.
HSAG's stated strategic rationale for acquiring VPI is to gain access to VPI's GaN-on-SiC power amplifier technology for integration into HSAG's commercial product lines, particularly its 5G telecommunications infrastructure products and its automotive power semiconductor products. HSAG has identified GaN technology as a critical growth area for the semiconductor industry, with applications in 5G base station power amplifiers, automotive radar systems, satellite communication terminals, and electric vehicle power conversion. HSAG's existing semiconductor design capabilities are concentrated in silicon (Si) and silicon-germanium (SiGe) technologies; VPI's GaN-on-SiC expertise would provide HSAG with a compound semiconductor platform that it has not previously possessed.
HSAG's planned post-closing integration activities include:
(i) Joint R&D collaboration between HSAG's semiconductor design centers in Dresden, Germany, and Austin, Texas, and VPI's engineering teams in Colorado Springs, Colorado, and Albuquerque, New Mexico, focused on the development of next-generation GaN power devices for commercial 5G infrastructure applications.
(ii) Transfer of VPI's GaN-on-SiC process knowledge and design methodologies to HSAG's existing design teams to enable development of new commercial GaN product lines for automotive radar and power conversion.
(iii) Cross-pollination of VPI's GaN-on-SiC expertise with HSAG's established silicon and SiGe semiconductor design capabilities, with the goal of developing integrated multi-technology solutions combining compound and conventional semiconductor technologies.
(iv) Potential future expansion of GaN manufacturing capacity at HSAG's European fabrication facilities, leveraging VPI's process technology.
As discussed in detail in Sections IV and V below, many of these integration objectives are materially constrained or entirely foreclosed by the NSA's IP transfer restrictions, at least in the near to medium term. The remainder of this memorandum is devoted to a detailed analysis of which integration activities are feasible, which are constrained, and what practical pathways may be available to HSAG to achieve its strategic objectives within the framework established by the NSA.
III. Overview of NSA IP Transfer Restriction Framework
This section provides an overview of the three principal structural elements of the NSA that, together, establish the comprehensive framework governing the transfer of VPI intellectual property to HSAG and its affiliates: (i) the core prohibition on technology transfer set forth in NSA Section 6; (ii) the Technology Control Plan set forth in NSA Annex B, which operationalizes the Section 6 prohibition through detailed procedures; and (iii) the data segregation and cybersecurity requirements set forth in NSA Annex D, which establish the technical infrastructure within which compliant information sharing must occur. These three elements are mutually reinforcing and must be understood as a unified system rather than as independent obligations.
A. Core Prohibition — NSA Section 6 (Technology Transfer)
NSA Section 6, titled "Technology Transfer," establishes the foundational prohibition governing the transfer of VPI intellectual property to HSAG and its affiliates. The provision is drafted broadly and is intended to capture all potential channels through which controlled technology could flow from VPI to non-U.S. persons associated with HSAG.
Prohibition. Section 6 prohibits the transfer of "Controlled Technical Data" (as defined in NSA Annex A — see Appendix A to this memorandum) from VPI to any "non-U.S. person," which term is defined to include: (a) all HSAG parent company personnel, regardless of their physical location; (b) employees of Halcyon US Inc. (Austin, Texas) who are not U.S. persons as defined under ITAR (22 C.F.R. § 120.62) and EAR (15 C.F.R. § 772.1); and (c) any HSAG affiliate worldwide, including all foreign subsidiaries, joint ventures, and representative offices. No transfer of Controlled Technical Data may occur without prior written authorization from the U.S. government, obtained through the appropriate regulatory channel (DDTC for ITAR-controlled data, BIS for EAR-controlled data, or the GSC for other categories of controlled information).
Definition of "Controlled Technical Data." The term "Controlled Technical Data" is defined in NSA Annex A to encompass the following categories:
(i) All technical data controlled under the International Traffic in Arms Regulations (ITAR), 22 C.F.R. Parts 120–130, including but not limited to defense articles, defense services, and technical data as defined in 22 C.F.R. § 120.33;
(ii) All technology and software controlled under the Export Administration Regulations (EAR), 15 C.F.R. Parts 730–774, including technology and software classified under any Export Control Classification Number (ECCN) on the Commerce Control List;
(iii) All classified information at any level of classification (CONFIDENTIAL, SECRET, TOP SECRET, or any compartmented or special access program information);
(iv) All VPI-designated proprietary information relating to government programs, including but not limited to contract performance data, test results, quality assurance methodologies, and manufacturing process information that, while not export-controlled or classified, is identified by VPI's Government Security Committee as sensitive to U.S. national security interests.
Scope of "Transfer." Critically, Section 6 defines "transfer" broadly to include all forms of communication or disclosure, whether physical, electronic, verbal, visual, or constructive. This definition specifically encompasses "deemed exports" within the meaning of EAR § 734.13, which treats the release of controlled technology to a foreign national within the United States as an export to that person's country of nationality or most recent country of citizenship. Accordingly, even the disclosure of controlled VPI technical data to a non-U.S. person physically present in the United States — for example, an HSAG German national employee temporarily stationed at VPI's Colorado Springs headquarters — constitutes a "transfer" subject to the Section 6 prohibition and requiring prior government authorization.
No Intra-Corporate Exception. The NSA does not contain any exception for intra-corporate transfers within the HSAG corporate group. This is a significant feature of the restriction framework: the fact that VPI will be a wholly owned subsidiary of HSAG (through Halcyon US Holdings Inc.) following the closing does not create any presumptive right to share controlled VPI technology within the HSAG group. Each proposed transfer must be evaluated and authorized independently under the applicable regulatory regime.
B. Technology Control Plan (NSA Annex B) Interaction
The Technology Control Plan, set forth in NSA Annex B, operationalizes the NSA Section 6 prohibition through a detailed system of information classification, access controls, and transfer procedures. The TCP is the primary mechanism through which day-to-day compliance with the IP transfer restrictions will be managed.
Information Classification System. The TCP establishes five categories for the classification of all VPI technical data and information:
(i) Classified Information. All information bearing a classification marking (CONFIDENTIAL, SECRET, TOP SECRET, or above) and all information associated with special access programs. Subject to the most restrictive access and transfer controls under the NISPOM and applicable security classification guides.
(ii) ITAR-Controlled Unclassified Information. All unclassified technical data, defense articles, and defense services subject to the International Traffic in Arms Regulations. Subject to DDTC export licensing requirements for any transfer to non-U.S. persons.
(iii) EAR-Controlled Unclassified Information. All unclassified technology and software subject to the Export Administration Regulations and classified under any ECCN on the Commerce Control List. Subject to BIS export licensing requirements, with potential applicability of license exceptions depending on the specific ECCN, destination, end-use, and end-user.
(iv) Government Program Proprietary Information. Unclassified, non-export-controlled information that relates to government programs and is designated by the GSC as sensitive to national security interests. This category encompasses a range of information that, while not legally controlled under ITAR or EAR, is treated as restricted under the NSA due to its nexus with U.S. government defense programs.
(v) Commercial/Non-Controlled Information. Information that is not classified, not export-controlled, not government-funded, and not designated as government program proprietary. This category represents VPI's purely commercial technical data and know-how with no nexus to defense programs or government funding.
Distinct Transfer Rules. Each of the five categories carries distinct rules governing access, transfer, and documentation. As will be discussed in detail in Section IV below, the practical effect of these tiered restrictions is that the vast majority of VPI's most commercially valuable intellectual property falls within Categories (i) through (iii), where transfer to HSAG is either absolutely prohibited or conditioned on prior government authorization that may be difficult or time-consuming to obtain.
Technology Classification Guide. The TCP requires VPI to develop, maintain, and regularly update a Technology Classification Guide (the "TCG") that identifies and classifies all VPI technical data by category. The TCG serves as the authoritative reference for determining whether any particular piece of VPI information may be shared with HSAG and, if so, under what conditions. As discussed in Section VIII.A below, completion of the TCG is the essential first step in the post-closing compliance process and should be prioritized.
Government Security Committee Authority. The TCP assigns exclusive authority over TCP administration for Categories (i) through (iv) to the Government Security Committee. The GSC is composed of three Security Board Members: Col. (Ret.) Bryce Hendrickson, who also serves as VPI's Facility Security Officer; Adrienne Delacroix; and the independent Security Director. The GSC functions as the decision-making body for all questions relating to the classification of VPI information, the review of proposed transfers of controlled information, and the administration of access controls. HSAG's designees on the reconstituted VPI board of directors do not have authority over TCP matters, nor do they have access to classified or controlled information held by VPI.
C. Data Segregation Requirements (NSA Annex D)
NSA Annex D establishes comprehensive cybersecurity and data segregation requirements designed to prevent unauthorized flows of VPI technical data to HSAG's global network. These requirements create the technical infrastructure within which all IP transfer compliance must operate.
Network Segregation. VPI's information technology systems — including all servers, workstations, data storage devices, and network infrastructure — must be physically and logically separated from HSAG's global corporate network. There shall be no shared cloud infrastructure, no common email domains, no shared network drives, no collaborative platforms (including but not limited to Northgate Data Systems, Meridian Solutions, Aldermere Systems, or equivalent systems), and no integrated enterprise resource planning (ERP) systems between VPI and any HSAG entity. This prohibition extends to all HSAG affiliates worldwide, including Halcyon US Inc. in Austin, Texas.
Information Gateway. Any electronic communication of non-controlled technical information between VPI and HSAG must pass through a defined "information gateway" that is administered by VPI's Facility Security Officer, Col. (Ret.) Bryce Hendrickson, and reviewed by the GSC. The information gateway is a controlled and monitored data transfer mechanism designed to ensure that only information properly classified as commercial/non-controlled (TCP Category (v)) — or information for which appropriate government authorization has been obtained — is transmitted from VPI's IT environment to HSAG's IT environment. All transfers through the information gateway are logged, and logs are subject to review by the third-party monitor during annual compliance audits.
Cybersecurity Standards. VPI's IT systems must comply with the cybersecurity requirements set forth in NIST Special Publication 800-171 (Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations). Compliance with NIST SP 800-171 is a condition of VPI's continued eligibility to perform on U.S. government contracts involving Controlled Unclassified Information (CUI) and is independently required by DFARS 252.204-7012.
Penetration Testing and Incident Reporting. VPI must engage a qualified third-party cybersecurity firm to conduct annual penetration testing of VPI's IT systems, with results reported to DCSA and the third-party monitor. Any cybersecurity incident involving potential unauthorized access to, or exfiltration of, controlled technical data must be reported to DCSA within 72 hours of discovery. The 72-hour reporting requirement is in addition to any other incident reporting obligations imposed by applicable federal regulations or government contract clauses.
The cumulative effect of these data segregation requirements is that VPI and HSAG will operate as distinct and separate entities from an information technology perspective for the foreseeable future. Even for commercial information that is not subject to substantive transfer restrictions, the administrative burden of routing all communications through the information gateway adds friction and delay to inter-company collaboration.
IV. Analysis by IP Category
This section analyzes the NSA's IP transfer restrictions as applied to each of the five categories of VPI intellectual property established by the TCP. For each category, we address the scope of IP falling within the category, the applicable transfer restrictions, the practical implications for HSAG's integration objectives, and any potential pathways for achieving authorized transfers.
A. Category 1: Classified Information and Related IP
Scope. This category encompasses all intellectual property associated with VPI's classified programs at the SECRET level and above. This includes all inventions, technical data, trade secrets, manufacturing process information, test data, and design specifications generated under VPI's classified contracts with the U.S. Department of Defense and other government agencies. Given the nature of VPI's defense business — which involves the design and manufacture of advanced GaN HEMT modules for some of the most sensitive U.S. military radar, electronic warfare, and missile defense systems — a significant and commercially valuable portion of VPI's IP portfolio falls within this category.
Applicable Contracts. VPI's classified programs include, but are not limited to, the following:
•  U.S. Army PEO IEW&S: Design and manufacture of GaN HEMT power amplifier modules for the AN/TPS-80 Ground/Air Task-Oriented Radar (G/ATOR) program, with a current contract backlog of $52.3 million.
•  Air Force Research Laboratory (AFRL): Development of next-generation millimeter-wave (mmWave) GaN power amplifiers for advanced electronic warfare and sensing applications, with a current contract backlog of $41.7 million.
•  Missile Defense Agency (MDA): Development and production of GaN-based transmit/receive (T/R) modules for phased array radar systems used in missile defense applications, with a current contract backlog of $38.9 million.
•  Ironclad Defense Systems Inc. (Subcontract — USN NAVSEA): Supply of GaN power amplifier assemblies as a subcontractor to Ironclad Defense Systems Inc. in support of U.S. Navy surface combatant radar programs administered by the Naval Sea Systems Command, with a current contract backlog of $34.1 million.
The aggregate backlog of VPI's classified programs is approximately $167 million, representing a substantial portion of VPI's forward revenue pipeline.
Transfer Restriction: Absolute Prohibition. The NSA imposes an absolute prohibition on the transfer of classified information and classified IP to any HSAG personnel, whether such personnel are U.S. persons or non-U.S. persons. This prohibition extends to HSAG's designees on the reconstituted VPI board of directors, who are specifically barred from access to classified information under the GSC charter (NSA Annex C). There is no mechanism within the NSA, the NISPOM, or any other regulatory framework for authorizing HSAG parent company access to VPI's classified IP. The classified IP remains under the exclusive control of the GSC and may be accessed only by VPI personnel holding the requisite security clearances and need-to-know authorization.
Facility Access. HSAG personnel may not access VPI classified facilities, including clean room Sections C-7 through C-12 of the Albuquerque fabrication facility, without prior approval from both DCSA and the GSC. As a practical matter, such approval is extremely unlikely to be granted for the purpose of technology access or R&D collaboration. Facility access approvals, if granted at all, would be limited to narrowly defined administrative purposes and would not entail access to classified technical data or manufacturing processes.
Practical Impact. HSAG will have no visibility into VPI's classified IP and cannot leverage it for any commercial application or any non-U.S. government application. This IP will remain within VPI, accessible only to cleared VPI employees operating under GSC direction. From HSAG's perspective, the classified IP is a "black box" — it generates revenue through VPI's government contract performance, but its substantive content is entirely inaccessible to HSAG's commercial R&D teams. HSAG's valuation of VPI should account for this reality: while the revenue stream from classified programs flows to HSAG as VPI's ultimate parent, the underlying technology cannot be leveraged for broader commercial purposes.
Patent Implications. Portions of VPI's patent portfolio incorporate classified subject matter, particularly certain patents within the HEMT gate structure optimization family (U.S. Patent Nos. 10,XXX,101 through 10,XXX,119) and the mmWave broadband matching network family (U.S. Patent Nos. 11,XXX,201 through 11,XXX,220). While the issued patents themselves are public documents, the underlying classified technical details — including classified embodiments, classified test data, and classified application-specific design information — cannot be discussed or shared with HSAG technical personnel. Some patents in these families may also be subject to secrecy orders issued by the U.S. Patent and Trademark Office under 35 U.S.C. § 181, which would impose additional restrictions on disclosure.
B. Category 2: ITAR-Controlled Unclassified IP
Scope. This category encompasses VPI products and technical data that are classified as ITAR Category XI(a)(3) defense articles under the United States Munitions List (USML), along with related manufacturing processes, design specifications, test data, and technical know-how. VPI's registration with the Directorate of Defense Trade Controls under Registration No. M-24817 reflects the scope of its ITAR-controlled activities. The ITAR-controlled portion of VPI's IP portfolio is extensive, encompassing a substantial majority of VPI's commercially valuable technology. Based on our review, we estimate that approximately 40% of VPI's 47 granted patents and approximately 20 of VPI's 31 registered trade secrets fall within this category.
Transfer Restriction. ITAR Section 127.1 (22 C.F.R. § 127.1) prohibits the export of defense articles, defense services, and related technical data to any non-U.S. person without prior authorization from the DDTC. The NSA reinforces this statutory and regulatory prohibition by incorporating it as a specific NSA obligation, meaning that a violation of ITAR export controls in the VPI context simultaneously constitutes a violation of the NSA, exposing HSAG to the NSA's independent penalty and enforcement mechanisms in addition to ITAR penalties.
VPI currently holds three active DSP-5 (permanent export license) authorizations for deliveries of specific GaN power amplifier products to NATO allies, specifically the United Kingdom and Australia. These existing licenses, however, do not authorize any transfers to HSAG's German operations or to any HSAG affiliate, and they require amendment to reflect the change of ownership of VPI. We have separately advised VPI on the required license amendment notifications to DDTC, which should be filed promptly following the closing. There is no existing Technical Assistance Agreement (TAA) or Manufacturing License Agreement (MLA) in place between VPI and HSAG or between VPI and any German entity that would cover the transfer of VPI's ITAR-controlled technology to HSAG.
Process for Obtaining Authorization. To transfer ITAR-controlled VPI technology to HSAG's German operations or to non-U.S. person employees of any HSAG entity, HSAG would need to pursue one of the following authorization pathways:
(i) Individual DSP-5 Licenses. HSAG could apply for individual DSP-5 permanent export licenses for each specific item of ITAR-controlled technology to be transferred. DSP-5 applications typically require 30 to 120 days for processing, but processing times for GaN defense technology transfers to foreign persons may be significantly longer due to the sensitivity of the technology and the heightened scrutiny applied to such applications. The outcome of any particular DSP-5 application is uncertain, and there is no guarantee that DDTC will approve a license for the transfer of defense-derived GaN amplifier technology to a German parent company.
(ii) Technical Assistance Agreement (TAA). Alternatively, HSAG could negotiate a TAA with DDTC that would provide a broader framework for ongoing technical data sharing and technical assistance between VPI and HSAG. A TAA is typically more appropriate than individual DSP-5 licenses when a sustained program of technology collaboration is contemplated. However, TAA negotiations can be lengthy (6 to 18 months is not uncommon for technology of this sensitivity), and the terms ultimately approved by DDTC may be significantly more restrictive than HSAG would prefer.
"Deemed Export" Considerations. The deemed export rule under ITAR (22 C.F.R. § 120.17, as recently renumbered) provides that any disclosure of ITAR-controlled technical data to a non-U.S. person within the United States constitutes an export to that person's country of nationality or most recent country of citizenship. This rule has direct and immediate relevance for HSAG's U.S. operations: any non-U.S. person employees at Halcyon US Inc. in Austin, Texas, or at VPI itself, may not receive access to ITAR-controlled VPI technical data without prior DDTC authorization. This is not merely a theoretical concern — Halcyon US Inc. in Austin employs engineers of various nationalities, and any exposure of non-U.S. person employees to ITAR-controlled VPI data would constitute an unauthorized export.
Impact on HSAG Integration Plans. The ITAR restrictions impose a material constraint on HSAG's ability to incorporate VPI's defense-derived GaN amplifier designs into its commercial product development. HSAG's stated objective of using VPI's GaN-on-SiC amplifier technology as the basis for commercial 5G base station power amplifiers and automotive radar products depends on access to the underlying design data, manufacturing process specifications, and performance optimization techniques that are, in large part, ITAR-controlled. Without DDTC authorization — which is uncertain in scope and timing — HSAG cannot share this technology with its R&D teams in Dresden or with non-U.S. person engineers at any location.
Trade Secrets. VPI's 31 registered internal trade secrets — primarily proprietary GaN epitaxial growth recipes and die-level reliability screening processes — largely overlap with ITAR-controlled technology. The epitaxial recipes define the specific process parameters for growing GaN layers used in defense-grade HEMT devices, and the reliability screening processes were developed to satisfy military specification requirements (e.g., MIL-PRF-38535 and MIL-STD-883). Sharing these trade secrets with HSAG's non-U.S. R&D teams is prohibited without prior DDTC authorization, and the extreme sensitivity of these processes makes it unlikely that blanket authorization would be granted.
C. Category 3: EAR-Controlled Dual-Use IP
Scope. This category encompasses VPI technical data and technology classified under Export Administration Regulations ECCNs 3A001 (certain microwave or millimeter-wave discrete devices and integrated circuits), 3A991 (electronic devices not controlled by 3A001 but still subject to EAR controls), and 3E001 (technology for the development or production of equipment controlled by, inter alia, ECCN 3A001). This includes design specifications for dual-use GaN components that have both defense and commercial applications, such as wideband GaN power amplifiers designed for both military radar and commercial 5G base station platforms, and broadband matching networks applicable to both electronic warfare and satellite communication systems. We estimate that approximately 25% of VPI's patent portfolio and approximately 6 of its 31 trade secrets fall primarily within this category.
Transfer Restriction. The export or re-export of EAR-controlled technology to HSAG personnel in Germany requires an export license issued by the Bureau of Industry and Security (BIS) unless an applicable license exception is available. The EAR regime is generally less restrictive than ITAR for transfers to NATO allies and Country Group B destinations (which includes Germany), but the dual-use nature of the technology and the specific ECCNs involved may limit the availability of license exceptions.
License Exception Analysis. We have conducted a preliminary analysis of the license exceptions potentially applicable to transfers of VPI's EAR-controlled technology to HSAG in Germany:
(i) License Exception TSR (Technology and Software under Restriction), 15 C.F.R. § 740.6. This exception may be available for certain transfers of ECCN 3E001 technology to Germany as a Country Group B destination, provided that the technology is not for military end-use or military end-users and does not involve certain specified restrictions. For VPI's commercially oriented GaN technology that has been independently classified under ECCN 3E001 (as distinct from technology that is also ITAR-controlled), License Exception TSR may provide a viable pathway for sharing certain design data with HSAG's German R&D teams without a specific BIS license. However, the applicability of TSR must be evaluated on a case-by-case basis, taking into account the specific technology parameters, the intended end-use, and any applicable restrictions under the relevant reasons for control.
(ii) License Exception TMP (Temporary Imports, Exports, Re-exports, and Transfers (In-Country)), 15 C.F.R. § 740.9. This exception has limited applicability in the context of sustained R&D collaboration, as it is designed for temporary technology transfers and requires that the technology be returned or otherwise disposed of within specified time limits.
(iii) Other Exceptions. We have also considered License Exception GOV (15 C.F.R. § 740.11), License Exception RPL (15 C.F.R. § 740.10), and License Exception STA (15 C.F.R. § 740.20), but none of these are broadly applicable to the contemplated technology transfers.
HSAG China Operations — Enhanced Scrutiny Risk. In assessing the likelihood of obtaining BIS export licenses for VPI technology transfers, we note that HSAG maintains operations in China through Halcyon Semiconductor (Shanghai) Co., Ltd., which generated revenue of approximately $81.4 million in fiscal year 2022, representing approximately 1.3% of HSAG's total revenue. While HSAG's China operations involve exclusively consumer-grade power management integrated circuits with no GaN or defense-related activities, the existence of an HSAG affiliate in China could create "red flags" in the license application review process. BIS examines the full corporate structure of the applicant when evaluating export license applications, and the presence of a Chinese subsidiary may trigger enhanced due diligence or delay in processing. We recommend that any BIS license applications clearly address the nature and scope of HSAG's China operations and include representations regarding the absence of any diversion risk.
Practical Pathway. For dual-use VPI technology eligible for license exceptions (particularly License Exception TSR), HSAG may be able to share certain commercially oriented GaN design data with its German R&D teams without obtaining specific BIS licenses. However, each proposed transfer must be preceded by a review against the TCP Technology Classification Guide to confirm the applicable ECCN classification and to verify that the technology does not contain ITAR-controlled elements that would preclude reliance on an EAR license exception. Additionally, any transfer of EAR-controlled technology, even under a license exception, must pass through the TCP information gateway and may require GSC review depending on the specific circumstances.
For technology that does not qualify for a license exception, HSAG must submit a license application to BIS, with typical processing times of 60 to 120 days. The outcome of such applications is generally favorable for transfers of dual-use semiconductor technology to NATO ally destinations, but case-specific factors — including the military potential of the specific technology, the end-use application, and the overall national security assessment — will determine the result.
Impact Assessment. The EAR restrictions impose a moderate constraint on HSAG's technology integration plans. Unlike the ITAR restrictions (which create a near-total bar absent specific government authorization), the EAR regime offers more realistic pathways for authorized technology sharing with HSAG's German operations. However, the process is not automatic — it requires careful classification analysis, potential license applications, and coordination with the GSC and TCP procedures. HSAG should expect that meaningful R&D collaboration involving EAR-controlled VPI technology will require 2 to 6 months to initiate through the proper channels, and ongoing collaboration will be subject to continuing compliance obligations.
D. Category 4: Government Program Proprietary IP (Uncontrolled but Sensitive)
Scope. This category encompasses VPI technical information that is not classified, not export-controlled under ITAR or EAR, but nevertheless relates to government programs and has been designated by the GSC as sensitive. Examples include unclassified contract performance data, testing methodologies developed with government funding, quality assurance processes specific to defense applications, and manufacturing process optimizations funded under government contracts but not separately controlled under export regulations. This category is significant because it captures a range of information that might otherwise appear to be freely shareable but is, under the NSA, subject to GSC oversight and approval requirements. We estimate that approximately 10% of VPI's patent portfolio falls primarily within this category.
NSA Restriction. The TCP designates this information as "Government Program Proprietary" and subjects it to GSC oversight. Any transfer of Government Program Proprietary information to HSAG requires prior written approval from the GSC. The GSC has discretion to approve, deny, or impose conditions on proposed transfers. GSC approval decisions are not subject to appeal to HSAG and may be overridden only by the CFIUS monitoring agencies.
Bayh-Dole Considerations. As noted in Section II.B, 23 of VPI's 47 granted U.S. patents were developed under U.S. government-funded contracts and constitute "subject inventions" under the Bayh-Dole Act. Even where such inventions are unclassified and not subject to export controls — i.e., where they fall into Category 4 rather than Categories 1 through 3 — the Bayh-Dole Act imposes several significant restrictions on VPI's (and by extension, HSAG's) freedom to exploit the technology:
(i) Government License. Under 35 U.S.C. § 202(c)(4), the government retains a nonexclusive, nontransferable, irrevocable, paid-up license to practice or have practiced each subject invention on behalf of the United States throughout the world. This license cannot be waived by VPI or HSAG and ensures that the government's ability to use the technology is not affected by the change of ownership.
(ii) Reporting and Disclosure Obligations. The Bayh-Dole Act and implementing regulations (37 C.F.R. Part 401), as supplemented by DFARS 252.227-7038, impose ongoing obligations to disclose subject inventions to the government, to elect title within specified time periods, and to report on the utilization of subject inventions through the iEdison system. We have confirmed, through a separate Government Rights in Subject Inventions Memo, that VPI's iEdison reporting obligations are current. HSAG must ensure that these obligations continue to be satisfied post-closing.
March-In Rights. Under 35 U.S.C. § 203, the federal government may exercise "march-in rights" — compelling the contractor to grant licenses to the government or third parties — if any of the following conditions is met:
(a) The contractor (VPI) or its assignee has not taken, or is not expected to take within a reasonable time, effective steps to achieve practical application of the subject invention;
(b) Action is necessary to alleviate health or safety needs which are not reasonably satisfied by the contractor or its assignee;
(c) Action is necessary to meet requirements for public use specified by federal regulations and such requirements are not reasonably satisfied by the contractor or its assignee; or
(d) The preference for U.S. manufacturing under 35 U.S.C. § 204 has been violated, i.e., the contractor has not agreed that any product embodying the subject invention will be manufactured substantially in the United States.
Manufacturing Preference. 35 U.S.C. § 204 requires that any products embodying government-funded subject inventions, or produced through the use of government-funded subject inventions, be manufactured substantially in the United States. This provision directly affects HSAG's potential plans to transfer VPI manufacturing processes to its European fabrication facilities. If HSAG were to move production of government-funded VPI inventions from VPI's Albuquerque fab to HSAG's Dresden fab, or to any other non-U.S. facility, this could constitute a violation of the § 204 manufacturing preference and trigger the government's march-in rights under § 203(a)(4). While waivers of the § 204 preference are theoretically available under 35 U.S.C. § 204(b), such waivers are granted only upon a showing that reasonable but unsuccessful efforts have been made to grant licenses to potential U.S. manufacturers or that domestic manufacture is not commercially feasible — a standard that would be difficult to meet given HSAG's existing U.S. manufacturing capability at VPI's Albuquerque facility.
Impact. Even where VPI technology is not export-controlled, the government funding restrictions imposed by the Bayh-Dole Act limit HSAG's freedom to move VPI R&D activities or manufacturing processes offshore. HSAG must maintain domestic manufacturing of products embodying government-funded inventions and must continue to satisfy all Bayh-Dole reporting and utilization requirements. The GSC's oversight authority over Government Program Proprietary information adds an additional layer of restriction that does not apply to purely commercial technology.
E. Category 5: Commercial / Non-Controlled IP
Scope. This category encompasses VPI technical data and know-how that is not classified, not export-controlled under ITAR or EAR, not developed with government funding, and not designated by the GSC as government program proprietary. This is the most permissive category, but it is also the narrowest in scope. Based on our analysis of VPI's IP portfolio — including a review of the government funding status of each patent, the export classification of each product family, and the relationship of each trade secret to government programs — we estimate that a relatively small portion of VPI's intellectual property falls into this purely commercial category: approximately 8 to 12 of VPI's 47 granted patents and 3 to 5 of VPI's 31 registered trade secrets.
The patents and trade secrets in this category relate primarily to VPI's non-defense commercial product designs, specifically commercial-grade 5G RF front-end components that were designed and developed without government funding and without reliance on ITAR-controlled or classified technology. These include certain lower-frequency GaN power amplifier designs for commercial cellular infrastructure and certain substrate preparation techniques developed for VPI's commercial product lines.
NSA Restriction. The NSA does not impose a specific prohibition on the intra-group sharing of commercial, non-controlled VPI intellectual property. However, the TCP requires that all VPI technical data be classified under the Technology Classification Guide before any transfer occurs, and all electronic communications of VPI technical data to HSAG entities must pass through the approved information gateway between VPI and HSAG IT systems, administered by VPI's FSO and subject to GSC oversight.
Practical Freedom. HSAG has the most latitude with respect to this category. Following proper classification of specific items of VPI technical data as commercial/non-controlled under the TCG, HSAG may share this IP with its global R&D teams, including teams in Dresden, Germany, subject to the following conditions:
(i) The TCP classification review must be completed and documented for each item of technical data before transfer;
(ii) All electronic data transfers must flow through the approved information gateway;
(iii) No controlled technical data may be inadvertently commingled with commercial data in the transfer; and
(iv) The transfer must be logged and documented for audit purposes.
Classification Risk. A critical caveat applies to this category: the boundary between EAR-controlled technology and non-controlled technology in the GaN semiconductor space is narrow and, in some cases, ambiguous. GaN technology has significant dual-use potential, and parameters such as operating frequency, power density, and efficiency that may differentiate controlled from non-controlled items can be difficult to assess definitively for design-stage technology. Misclassification — inadvertently treating EAR-controlled technology as non-controlled — would constitute a violation of both the EAR and the NSA, potentially exposing HSAG to penalties under both regimes. The annual compliance audits conducted by Whitmore Compliance Group will specifically scrutinize the accuracy of TCG classification decisions, and any pattern of misclassification would be reported to CFIUS monitoring agencies as a compliance deficiency.
HSAG should take a conservative approach to classification decisions and, in cases of doubt, should treat technology as EAR-controlled and pursue the appropriate licensing pathway rather than risk an inadvertent violation. Calderwood & Harkness is available to assist with specific classification determinations as they arise.
V. Specific Constraints on HSAG's Planned R&D Integration
Building on the category-by-category analysis in Section IV, this section addresses the NSA's impact on each of HSAG's four principal planned R&D integration activities.
A. Cross-Border R&D Collaboration Between VPI and HSAG Dresden
HSAG's Planned Model. HSAG's integration plan contemplates establishing joint R&D teams comprising VPI engineers in Colorado Springs and Albuquerque and HSAG engineers in Dresden, Germany, working collaboratively on the development of next-generation GaN power devices for commercial 5G infrastructure applications. This model envisions shared access to design databases, joint simulation and modeling activities, collaborative design reviews, and regular exchange of technical data between the two locations.
NSA Impact. This collaboration model is effectively prohibited in its contemplated form under the NSA restrictions. Specifically:
(i) Controlled Technical Data. To the extent that the GaN power device technology under development involves controlled technical data — which, given VPI's IP portfolio composition, is the likely case for the vast majority of VPI's GaN technology — the cross-border sharing of design data, simulation results, and manufacturing process information with HSAG's Dresden engineers is prohibited absent prior government authorization through DDTC (for ITAR-controlled data) or BIS (for EAR-controlled data). As discussed in Section IV.B and IV.C, obtaining such authorization is uncertain and time-consuming.
(ii) Data Segregation. NSA Annex D's data segregation requirements prevent VPI and HSAG from using shared computational tools, simulation platforms, or design databases. The prohibition on shared cloud infrastructure, collaborative platforms, and integrated ERP systems means that even if certain technology transfers were authorized, the technical infrastructure for seamless real-time collaboration does not exist and cannot be created under the current NSA framework.
(iii) TCP Controls. All technical data flowing from VPI to HSAG must pass through the TCP information gateway, which is administered by VPI's FSO and reviewed by the GSC. This gateway operates as a bottleneck through which each data transfer is individually evaluated for compliance. The gateway process is incompatible with the kind of fluid, real-time collaboration contem
