3. Description of the MNE Group's Business(es)
3.1 Overview of Halcyon Group Business
The Halcyon Group is a global semiconductor company engaged in the design, development, fabrication, and distribution of advanced-node semiconductor wafers and singulated die. HSAG is a vertically integrated semiconductor manufacturer, performing both the front-end wafer fabrication (foundry operations) and the back-end assembly, test, and packaging functions at its facilities in Germany. The Group specializes in advanced process technology nodes, including 7-nanometer ("7nm"), 5-nanometer ("5nm"), and 3-nanometer ("3nm") fabrication processes.
The Group's semiconductor products serve three principal end markets:
•  Automotive Semiconductors: The Halcyon Group supplies advanced semiconductor components for automotive applications, including advanced driver-assistance systems (ADAS), vehicle electrification (power management ICs, battery management systems), in-vehicle networking, and infotainment systems. The automotive segment represents the Group's largest revenue contributor and is characterized by long product qualification cycles and multi-year supply agreements with major automotive OEMs.
•  Industrial Internet of Things (IoT): The Group provides semiconductors for industrial automation, smart manufacturing, edge computing, and sensor applications. The Industrial IoT segment benefits from growing demand for high-performance, low-power semiconductor solutions in industrial environments.
•  Data-Center Applications: The Group supplies advanced semiconductor products for hyperscale data centers, including high-performance computing (HPC) accelerators, networking components, and memory interface ICs. This segment has experienced rapid growth driven by artificial intelligence (AI) training and inference workloads.
The Halcyon Group operates a vertically integrated business model in which HSAG performs wafer fabrication at its German facilities and distributes finished products through regional subsidiaries. HSI serves as the primary distribution channel for the North American market, purchasing semiconductor wafers and die from HSAG and reselling finished products to unrelated US customers. HSJ and HSC perform analogous distribution and sales support functions in Japan and China, respectively.
As of December 31, 2024, the Halcyon Group employed approximately 22,400 individuals worldwide, of whom approximately 14,600 (approximately 65%) were based in Germany at HSAG's Dresden and Chemnitz facilities. The Group's global workforce includes semiconductor process engineers, design engineers, R&D scientists, manufacturing technicians, sales and marketing professionals, and corporate support staff.
For FY 2024, the Halcyon Group reported the following consolidated financial results:
•  Consolidated Revenue: €8,740,000,000
•  Consolidated EBITDA: €2,620,000,000 (EBITDA margin: 30.0%)
•  Consolidated Operating Income (EBIT): €1,570,000,000 (EBIT margin: 18.0%)
These results reflect the Group's strong competitive position in the advanced semiconductor fabrication market and its ability to generate significant operating margins through a combination of technology leadership, operational efficiency, and long-term customer relationships.
3.2 Important Drivers of Business Profit
The profitability of the Halcyon Group is driven by several interrelated factors that reflect the Group's competitive advantages, the capital-intensive nature of advanced semiconductor fabrication, and the dynamics of the global semiconductor industry:
Advanced Process Technology Leadership. HSAG is among a limited number of semiconductor companies worldwide capable of manufacturing at the most advanced process nodes (3nm and below). The ability to fabricate at these nodes requires significant accumulated know-how, specialized equipment, and years of iterative process development. This technology leadership enables HSAG to command premium pricing, achieve higher yields over time, and attract customers with demanding performance requirements.
High Barriers to Entry. The semiconductor fabrication industry is characterized by extraordinarily high barriers to entry. The construction of a single advanced-node fabrication facility requires capital expenditures typically exceeding €5 billion, with lead times of three to five years from groundbreaking to high-volume production. These barriers limit the number of competitors capable of operating at the technology frontier and confer significant competitive advantages upon incumbents such as HSAG.
Long-Term Supply Agreements. The Halcyon Group benefits from long-term supply agreements with major automotive OEMs and hyperscale data-center operators. These agreements, which typically span three to seven years, provide revenue visibility, reduce demand volatility, and enable efficient capacity planning. The qualification processes for automotive-grade semiconductors, in particular, create substantial switching costs for customers, further reinforcing the durability of customer relationships.
Significant R&D Investment. The Halcyon Group invested €1,420,000,000 in research and development during FY 2024, representing approximately 16.2% of consolidated revenue. This investment supports the ongoing development of next-generation process technologies (including 2nm and sub-2nm nodes), the enhancement of existing process capabilities, and the creation of new design libraries and intellectual property. A subset of this R&D expenditure — specifically, €998,200,000 in Qualified CSA R&D Costs — is attributable to the joint next-generation process development activities conducted under the Cost Sharing Arrangement between HSAG and HSI, as further described in Section 4 of this Master File.
Operational Efficiency and Yield Optimization. HSAG has developed proprietary fabrication yield optimization techniques and process recipes that enable it to achieve industry-leading yields on advanced-node wafers. These yield improvements translate directly into lower unit costs and higher gross margins, representing a critical source of competitive advantage.
3.3 Supply Chain Description
The Halcyon Group's global supply chain operates as a hub-and-spoke model, with HSAG serving as the central manufacturing and intellectual property hub and regional subsidiaries performing distribution and customer-facing functions in their respective markets. The supply chain can be described as follows:
Manufacturing (HSAG — Germany). HSAG fabricates semiconductor wafers at its three fabs in Dresden (Fab 1 and Fab 2) and Chemnitz (Fab 3). The fabrication process involves hundreds of individual processing steps, including photolithography, etching, deposition, ion implantation, and chemical-mechanical planarization. Following wafer fabrication, HSAG performs wafer testing, die singulation (dicing), and in certain cases, assembly and packaging at its German facilities. HSAG sources raw materials — including silicon wafers, photomasks, specialty chemicals, and process gases — from unrelated third-party suppliers.
Intercompany Supply (HSAG → HSI, HSJ, HSC). Finished semiconductor wafers and singulated die are sold intercompany from HSAG to HSI under the Master Intercompany Supply Agreement, which was originally executed effective January 1, 2019 and was subsequently amended on July 1, 2022. Similar intercompany supply arrangements govern the flow of goods from HSAG to HSJ and HSC for their respective markets. The transfer prices for intercompany tangible goods transactions are set in accordance with the Group's transfer pricing policies, as further described in Sections 6 and 7 of this Master File.
Distribution and Resale (HSI — United States). HSI purchases finished and packaged semiconductors from HSAG and resells them to unrelated US customers, including automotive OEMs, electronic component distributors, and hyperscale data-center operators. HSI performs marketing, order management, customer service, technical support, and limited design support functions in connection with these resale activities. HSI does not perform wafer fabrication or semiconductor manufacturing.
Distribution and Customer Support (HSJ — Japan; HSC — China). HSJ performs distribution, marketing, and customer support functions for the Japanese market, analogous to HSI's role in the United States. HSC performs sales representation, customer support, and limited design adaptation functions for the Greater China market, operating in a commissionnaire-type capacity.
Summary of Principal Intercompany Transaction Categories (US-Germany Supply Chain). The three principal categories of intercompany transactions in the US-Germany supply chain, which are the focus of this Master File and the bilateral APA proceedings, are as follows:
1.  Tangible Goods (Wafer/Die Sales): HSAG sells finished semiconductor wafers and singulated die to HSI under the Master Intercompany Supply Agreement.
2.  Royalties (IP License): HSI pays a running royalty to HSAG under the IP License Agreement for the right to use HSAG's proprietary semiconductor process technology, design libraries, and related intangibles in connection with HSI's US distribution and design support activities.
3.  Cost-Sharing Contributions (R&D CSA): HSI makes cost-sharing contributions to HSAG under the Cost Sharing Arrangement in respect of joint development of next-generation 2nm and sub-2nm process technology.
3.4 Principal Geographic Markets Served
The Halcyon Group serves customers in all major semiconductor end markets worldwide. The principal geographic markets, as defined by the location of the Group's third-party customers, are as follows:
North America (through HSI). North America is the Halcyon Group's largest single market by revenue. In FY 2024, HSI generated third-party revenue of $4,120,000,000 from sales to unrelated US customers. Key customer segments in North America include automotive OEMs headquartered in Michigan and the broader Midwest, hyperscale data-center operators concentrated in the Western United States, and electronic component distributors serving a diverse range of end markets. The North American market accounted for a significant portion of the Group's consolidated revenue in FY 2024.

HSAG sells a substantial volume of semiconductor products directly to European customers, including major automotive OEMs headquartered in Germany, France, and the broader European Union. European sales are conducted primarily from HSAG's headquarters in Dresden and do not involve intercompany transactions with regional subsidiaries. European revenue represents a significant portion of consolidated revenue and benefits from the Group's proximity to the European automotive industry's engineering and procurement centers.
Japan (through HSJ). HSJ distributes semiconductor products to Japanese customers, including automotive OEMs, industrial electronics manufacturers, and consumer electronics companies. The Japanese market is a mature and technologically sophisticated semiconductor market, requiring local-language technical support and customer relationship management.
China (through HSC). HSC provides sales representation and customer support for the Greater China market, facilitating sales between HSAG and Chinese customers. The Chinese semiconductor market has experienced significant growth in recent years, driven by demand in automotive electrification, telecommunications infrastructure, and consumer electronics.
3.5 Key Competitors
The Halcyon Group operates in the advanced semiconductor fabrication industry, which is characterized by a limited number of competitors capable of manufacturing at the most advanced process nodes. The competitive landscape includes both integrated device manufacturers (IDMs) that design and fabricate their own semiconductors and pure-play foundry operators that fabricate semiconductors on behalf of fabless design companies.
Competition in the advanced semiconductor fabrication market is driven primarily by process technology capability (i.e., the ability to manufacture at the smallest process nodes), fabrication yield, manufacturing capacity, customer relationships, and total cost of ownership for the customer. The industry is characterized by cyclicality in demand, particularly in the automotive and industrial segments, where end-market production volumes are sensitive to macroeconomic conditions. The capital intensity of advanced semiconductor fabrication — with single-fab construction costs exceeding €5 billion and equipment lead times of 18 to 24 months — creates significant barriers to entry and limits the number of viable competitors at the technology frontier.
The Halcyon Group's competitive position is strengthened by its vertically integrated business model, its portfolio of proprietary process technology IP, its long-term relationships with major automotive OEMs and hyperscaler customers, and its significant and sustained investment in R&D. The Group's ability to offer automotive-grade reliability and quality, combined with advanced-node manufacturing capability, differentiates it from competitors that may offer either automotive-grade legacy-node products or advanced-node products for non-automotive applications, but not both.

The vast majority of the Group's R&D activities are centralized in Germany, conducted under the direction of HSAG's Chief Technology Officer, Dr. Hendrik Möller, at the Dresden and Chemnitz facilities. HSAG's R&D organization encompasses process technology development (including the development of new and improved fabrication processes at each technology node), design library development (including the creation of proprietary standard cell IP, I/O libraries, and design kits), and fundamental materials science and device physics research.
In FY 2024, the Halcyon Group's total R&D expenditure amounted to €1,420,000,000, representing approximately 16.2% of consolidated revenue. This investment underscores the Group's commitment to maintaining and extending its technology leadership at the most advanced process nodes.
HSAG's IP exploitation strategy involves licensing certain intangible property to its regional subsidiaries to enable them to perform their local distribution, marketing, and design support functions. Specifically, HSAG licenses proprietary semiconductor process technology, design libraries, and related intangibles to HSI under the IP License Agreement (effective January 1, 2019), to HSJ under a separate licensing arrangement for the Japanese market, and to HSC under a similar arrangement for the Chinese market. The licensing arrangements with HSJ and HSC are not within the primary scope of this Master File.
In addition to the licensing of existing intangibles, HSI participates in the co-development of next-generation process technology through the Qualified Cost Sharing Arrangement (effective July 15, 2018). Under the CSA, HSI makes periodic cost-sharing contributions to HSAG in exchange for the right to exploit the jointly developed intangible property in the North American market. The CSA is described in detail in Section 4.3.2 below.
4.2 List of Intangibles and Intangible Owners
The following table summarizes the principal categories of intangible property held within the Halcyon Group, together with the legal and economic owner of each:
The relative value of the intangible property held within the Halcyon Group is overwhelmingly concentrated in HSAG. HSAG's process technology IP, design libraries, patents, and trade secrets represent the Group's core value-driving intangibles, enabling the design and fabrication of advanced-node semiconductor products that command premium pricing in the global market. By contrast, the marketing intangibles held by HSI — while commercially relevant to HSI's distribution activities in North America — are of modest value relative to HSAG's technology intangibles and are largely derivative of the value created by HSAG's underlying process technology.
4.3 Description of Important Intangible Transactions
4.3.1 IP License Agreement (HSAG → HSI)
Effective January 1, 2019, HSAG entered into an IP License Agreement with HSI pursuant to which HSAG licenses to HSI certain proprietary semiconductor process technology, design libraries, and related intangible property for use in HSI's distribution and design support activities in the United States. The principal terms of the IP License Agreement are as follows:
•  Licensor: HSAG
•  Licensee: HSI
•  Licensed Intangibles: Proprietary semiconductor process technology (7nm, 5nm, and 3nm), design libraries (standard cell IP, I/O libraries, design kits), and related technical documentation and know-how
•  License Scope: Non-exclusive license to use the licensed intangibles in connection with HSI's distribution, marketing, and design support activities in the United States and its territories
•  Royalty Rate: 6.0% running royalty on IP-attributable revenues, payable quarterly in arrears
•  IP-Attributable Revenue Calculation: The royalty is calculated on the IP-attributable share of HSI's net US revenues, determined as 18.1% of HSI's third-party net revenue. This percentage reflects the portion of HSI's revenue attributable to the exploitation of the licensed intangibles, as determined through a functional analysis and allocation methodology specified in the IP License Agreement.
•  FY 2024 Royalty Payments: €68,400,000 (approximately $70,500,000 at the weighted average payment-date EUR/USD exchange rate of 1.0307)
The calculation of the FY 2024 royalty payment is as follows:
•  HSI's FY 2024 net US revenue: $4,120,000,000
•  IP-attributable share of net US revenue: 18.1%
•  IP-attributable revenue: $4,120,000,000 × 18.1% = $745,720,000
•  Royalty rate: 6.0%
•  Royalty in USD terms: $745,720,000 × 6.0% = $44,743,200
•  EUR-denominated contractual amount: €68,400,000 (reflecting the currency mechanics specified in the IP License Agreement, under which the royalty is invoiced in EUR based on applicable exchange rates at the time of each quarterly payment)
The arm's-length nature of the 6.0% royalty rate is supported by a Comparable Uncontrolled Transaction ("CUT") analysis based on eight comparable license agreements identified in the Clearpoint Royalty Database and public SEC filings. The interquartile range ("IQR") of royalty rates for the comparable agreements is 3.5% to 8.2%, with a median of 5.6%. The 6.0% royalty rate falls within this IQR and is further corroborated by a residual profit split analysis. Detailed benchmarking results are provided in the US and German Local Files and are summarized in Appendix C to this Master File.
4.3.2 Cost Sharing Arrangement (HSAG & HSI)
Effective July 15, 2018, HSAG and HSI entered into a Cost Sharing Arrangement (the "CSA") for the joint development of next-generation 2nm and sub-2nm semiconductor fabrication process technology. The CSA is structured as a Qualified Cost Sharing Arrangement under Treasury Regulation § 1.482-7.
The principal terms and features of the CSA are as follows:
•  Participants: HSAG and HSI
•  Subject Matter: Joint development of next-generation 2nm and sub-2nm process technology, including process integration, device engineering, photolithography advances, and related design library development
•  HSI's Anticipated Benefit Share: 22.5%, reflecting HSI's proportionate anticipated benefit from the exploitation of the jointly developed intangible property in the North American market. The anticipated benefit shares are determined using the income method, based on projected revenue and profitability attributable to the exploitation of the CSA-developed intangibles in each participant's geographic territory.
•  HSAG's Anticipated Benefit Share: 77.5%, reflecting HSAG's proportionate anticipated benefit from exploitation in all markets other than North America (principally Europe, Japan, and China)
•  FY 2024 Total Qualified R&D Costs: €998,200,000 (a subset of HSAG's total R&D expenditure of €1,420,000,000, encompassing those R&D costs directly attributable to the joint next-generation process development activities covered by the CSA)
•  HSI's FY 2024 Cost-Sharing Contribution: €998,200,000 × 22.5% = €224,600,000 (approximately $231,300,000)
•  Benefit Share Review: The anticipated benefit shares are subject to review and adjustment on a triennial basis, in accordance with the terms of the CSA and the requirements of Treasury Regulation § 1.482-7
Platform Contribution Transaction (PCT). At the inception of the CSA on July 15, 2018, HSI made a buy-in payment (Platform Contribution Transaction) to HSAG of $312,500,000. The PCT payment compensated HSAG for HSI's acquisition of the right to participate in the CSA and to exploit the pre-existing intangible property (including process technology and design library IP) that was made available as a platform for the joint development activities under the CSA.
The PCT payment was valued using the income method, consistent with Treasury Regulation § 1.482-7(g)(4). The valuation was performed by Stonebridge Valuation Partners LLC (Marcus Reinhardt, Managing Director; office: 200 Park Avenue, Suite 1510, New York, NY 10166). The key parameters of the PCT valuation were:
•  Valuation method: Income method
•  discount rate: 11.8% (weighted average cost of capital, adjusted for risk)
•  Projection period: 15 years
•  Projected cash flows attributable to the exploitation of pre-existing intangibles in the North American market
The PCT payment and the ongoing cost-sharing contributions are documented in the CSA agreement and are further analyzed in the US and German Local Files.
4.4 Transfer Pricing Policies for Intangibles
The transfer pricing policies for intangible property transactions within the Halcyon Group are designed to ensure compliance with the arm's-length principle, as articulated in Article 9 of the OECD Model Tax Convention, the OECD Transfer Pricing Guidelines (2022 edition), and the applicable domestic transfer pricing rules of each relevant jurisdiction.
Royalty Rate (IP License Agreement). The 6.0% running royalty rate under the IP License Agreement is established at arm's length based on a CUT analysis employing eight comparable license agreements. The comparable agreements were identified through a systematic search of the Clearpoint Royalty Database and public SEC filings for technology license agreements in the semiconductor industry and analogous capital-intensive technology sectors. The interquartile range of royalty rates for the comparable agreements is 3.5% to 8.2%, with a median of 5.6%. The contractual royalty rate of 6.0% falls within this range. The CUT analysis is corroborated by a residual profit split analysis, which confirms that the allocation of residual profits between HSAG (as the owner of core technology intangibles) and HSI (as a limited-risk distributor/design support entity) is consistent with the arm's-length standard.
Cost-Sharing Contributions (CSA). HSI's cost-sharing contributions are determined based on the anticipated benefit share methodology prescribed by Treasury Regulation § 1.482-7. The income method is used to determine the anticipated benefit shares of each participant, based on projected revenue and profitability attributable to the exploitation of the CSA-developed intangibles in each participant's geographic territory. The anticipated benefit shares are reviewed and, if appropriate, adjusted on a triennial basis.
Detailed economic analyses supporting these transfer pricing policies are provided in the US and German Local Files and in the economic reports prepared by Meridian Economics GmbH. Appendix C to this Master File provides a summary of the key benchmarking results. Cross-reference is also made to the APA application, which will present these analyses in the context of the proposed bilateral APA.
5. MNE Group's Intercompany Financial Activities
5.1 Description of How the MNE Group Is Financed
The Halcyon Group's financing structure reflects the central role of HSAG as the Group's principal operating entity and primary source of capital. HSAG raises capital through the public equity markets (as a company listed on the Frankfurt Stock Exchange/XETRA) and through the European debt capital markets. HSAG's access to the capital markets is supported by its investment-grade credit profile, strong cash flow generation, and the visibility of its revenue streams from long-term supply agreements.
HSI maintains a $600,000,000 revolving credit facility with Ridgeline National Bank (the "HSI Revolver"). Ridgeline National Bank serves as the administrative agent for the facility, with Daniel Furlong as the senior relationship manager (headquarters: 401 South Tryon Street, Charlotte, NC 28202). The HSI Revolver is utilized by HSI for working capital and operational needs, including the financing of trade receivables and inventory in connection with its US distribution activities. The HSI Revolver is a third-party facility between HSI and Ridgeline National Bank; it does not involve any intercompany guarantee or credit support from HSAG.
Importantly, there are no intercompany financing arrangements of significance between HSAG and HSI. HSI does not borrow from HSAG, and HSAG does not provide intercompany loans, guarantees, or other credit support to HSI in connection with HSI's US operations. This financing structure is consistent with the characterization of HSI as a limited-risk distributor that maintains its own independent access to third-party financing for its working capital requirements.
HSJ and HSC are financed through a combination of HSAG intercompany loans and local credit facilities. The intercompany loans to HSJ and HSC are de minimis relative to the Group's consolidated financial position and are not material to the transfer pricing analysis of the US-Germany controlled transactions that are the focus of this Master File.
5.2 Identification of MNE Group Members Providing Central Financing Functions
HSAG Group Treasury, headquartered in Dresden, performs the Group's centralized financing functions, including:
•  Centralized cash pooling across the Group's European entities
•  Foreign exchange hedging and currency risk management
•  Capital allocation and investment planning
•  Management of the Group's external financing relationships (bank credit facilities, debt issuances, and equity capital markets activities)
HSAG's CFO, Margarethe Stein, oversees the Group's financial strategy, including capital structure decisions, dividend policy, and the allocation of capital among the Group's operating entities and R&D programs. The Group Treasury function is staffed by approximately 35 professionals based in Dresden.
5.3 Intercompany Financial Transactions
During FY 2024, there were no material intercompany loans or other intercompany financing transactions between HSAG and HSI. The principal intercompany financial flows between HSAG and HSI arise from the tangible goods transactions (wafer/die sales), royalty payments (IP License Agreement), and cost-sharing contributions (CSA) described in Sections 4 and 6 of this Master File. These intercompany trade receivables and payables are settled on standard 60-day payment terms in accordance with the applicable intercompany agreements.
The following exchange rates were used in connection with the FY 2024 intercompany transactions:
•  Average 2024 EUR/USD exchange rate: 1.0896 — used for the annual conversion of intercompany tangible goods purchases (wafer/die sales) denominated in EUR to USD equivalents for financial reporting purposes
•  Weighted average payment-date EUR/USD rate (royalty payments): 1.0307 — used for the conversion of quarterly royalty payments, reflecting the actual EUR/USD exchange rates at the time of each quarterly payment
Further detail on the exchange rates used and the sources and methodology for exchange rate determinations is provided in Appendix F to this Master File.
5.4 Transfer Pricing Policies for Financial Transactions
Given the absence of material intercompany financing transactions between HSAG and HSI, there are no significant transfer pricing implications arising from financial transactions in the US-Germany context. Trade payables between HSAG and HSI are settled at contractual terms (60 days), which are consistent with prevailing market practice for intercompany trade payables between affiliated entities in the semiconductor industry.
Intercompany financing to HSJ and HSC — consisting of intercompany loans extended by HSAG to fund local working capital requirements — is priced at arm's length based on the credit quality of the borrower entity and comparable market interest rates for loans of similar tenor, currency, and credit risk profile. The intercompany financing to HSJ and HSC is not within the scope of the bilateral US-Germany APA and is documented separately in the relevant Local Files for those jurisdictions.
6. MNE Group's Intercompany Transactions — Summary
6.1 Summary of Controlled Transactions (US-Germany)
The following table summarizes the FY 2024 intercompany transaction flows between HSAG and HSI, which comprise the controlled transactions that are the focus of this Master File and the bilateral APA proceedings:
The aggregate intercompany transaction volume of approximately €1.28 billion (approximately $1.28 billion at average exchange rates) represents the totality of controlled transactions between HSAG and HSI for FY 2024. These transactions are governed by three intercompany agreements described in Section 6.2 below and are priced in accordance with the transfer pricing methods summarized in Section 6.3 below.
6.2 Intercompany Agreements Governing Controlled Transactions
The controlled transactions between HSAG and HSI are governed by the following intercompany agreements, each of which has been executed between HSAG and HSI and is maintained in the Group's transfer pricing documentation files:
1.  Master Intercompany Supply Agreement (HSAG–HSI): Effective January 1, 2019; amended July 1, 2022. This agreement governs the sale of semiconductor wafers and singulated die from HSAG to HSI, including pricing mechanisms, delivery terms, quality standards, warranty provisions, and settlement terms.
2.  IP License Agreement (HSAG–HSI): Effective January 1, 2019. This agreement governs the license of proprietary semiconductor process technology, design libraries, and related intangibles from HSAG to HSI, including the royalty rate, the definition of IP-attributable revenues, payment terms, and the scope of the licensed rights.
3.  Cost Sharing Arrangement (HSAG–HSI): Effective July 15, 2018. This agreement governs the joint development of next-generation 2nm and sub-2nm process technology, including the determination of anticipated benefit shares, the calculation and payment of cost-sharing contributions, the Platform Contribution Transaction, and the triennial review of benefit shares.
Summaries of the key terms of each agreement are provided in Appendix B to this Master File. Copies of the executed agreements are available for review by the relevant tax authorities upon request, subject to the confidentiality protections described in Section 1.4 of this Master File.
6.3 Transfer Pricing Methods — Overview
The following table summarizes the transfer pricing methods applied to each category of controlled transaction between HSAG and HSI:
Tangible Goods — TNMM/CPM. The Transactional Net Margin Method ("TNMM"), equivalent to the Comparable Profits Method ("CPM") under US Treasury Regulations, has been selected as the most appropriate transfer pricing method for the tangible goods (wafer/die sales) transactions between HSAG and HSI. HSI has been identified as the tested party, as it is the least complex party to the controlled transaction and performs routine distribution functions. The profit level indicator ("PLI") is HSI's operating margin on net resales. The benchmarking study identifies 17 comparable companies that perform distribution functions in the semiconductor and electronic components industries, using financial data from FY 2020 through FY 2024 (five-year weighted average). The interquartile range of operating margins for the comparable companies is 2.8% to 6.1%, with a median of 4.4%.
Royalties — CUT. The Comparable Uncontrolled Transaction ("CUT") method has been selected as the most appropriate transfer pricing method for the royalty payments under the IP License Agreement. The CUT analysis identifies eight comparable license agreements from the Clearpoint Royalty Database and public SEC filings, involving the licensing of semiconductor or analogous technology intangibles. The interquartile range of royalty rates for the comparable agreements is 3.5% to 8.2%, with a median of 5.6%. The CUT analysis is corroborated by a residual profit split analysis.
Cost Sharing — Income Method. HSI's cost-sharing contributions under the CSA are determined using the income method prescribed by Treasury Regulation § 1.482-7. The anticipated benefit shares are calculated based on projected revenue and profitability attributable to the exploitation of the CSA-developed intangibles in each participant's territory. HSI's anticipated benefit share is 22.5%, reflecting its proportionate anticipated benefit from North American exploitation rights.
6.4 Arm's-Length Results — FY 2024 Snapshot
The following summarizes the arm's-length results of the Halcyon Group's US-Germany controlled transactions for FY 2024:
HSI Operating Margin (TNMM/CPM):
HSI's FY 2024 operating margin on net resales was 4.80%, calculated as follows:
•  HSI FY 2024 operating income: $197,800,000
•  HSI FY 2024 net revenue (third-party US sales): $4,120,000,000
•  Operating margin: $197,800,000 ÷ $4,120,000,000 = 4.80%
HSI's operating margin of 4.80% falls within the interquartile range of 2.8% to 6.1% established by the benchmarking study of 17 comparable companies and is slightly above the median of 4.4%. This result confirms that HSI's operating profitability is consistent with the arm's-length standard for a limited-risk distributor and design support entity.
HSAG Royalty Rate (CUT):
The 6.0% royalty rate under the IP License Agreement falls within the interquartile range of 3.5% to 8.2% established by the CUT analysis of eight comparable license agreements and is slightly above the median of 5.6%. This result confirms that the royalty rate is consistent with the arm's-length standard for a technology license of comparable scope and value.
HSI Cost-Sharing Percentage (Income Method):
HSI's cost-sharing percentage of 22.5% is consistent with the anticipated benefit share analysis, which allocates costs in proportion to the projected economic benefits each participant is expected to derive from the CSA-developed intangibles. The benefit shares were last reviewed and confirmed in FY 2024 in connection with the scheduled triennial review.
6.5 Transactions with Other Group Entities (HSJ, HSC)
In addition to the controlled transactions between HSAG and HSI described above, the Halcyon Group maintains intercompany transactions between HSAG and its other subsidiaries:
HSAG–HSJ (Japan). HSAG sells semiconductor wafers and die to HSJ under a separate intercompany supply agreement. HSJ performs distribution, marketing, and customer support
