PRIVILEGED AND CONFIDENTIAL — ATTORNEY WORK PRODUCT
CALDERWOOD & HARKNESS LLP 599 Lexington Avenue, 38th Floor New York, NY 10022
MEMORANDUM
PRIVILEGE DESIGNATION: This memorandum is protected by the attorney-client privilege and attorney work product doctrine. It contains confidential legal analysis and strategic advice prepared in anticipation of adversarial proceedings and negotiations with the IRS Advance Pricing and Mutual Agreement Program ("APMA") and, through the competent authority process, the German Bundeszentralamt für Steuern ("BZSt"). This memorandum reflects the mental impressions, conclusions, opinions, and legal theories of attorneys at Calderwood & Harkness LLP. Do not distribute outside Calderwood & Harkness LLP without the express authorization of Leonard Cross. Any inadvertent disclosure does not constitute a waiver of any applicable privilege.
I. Purpose and Scope of This Memorandum
This memorandum sets forth Calderwood & Harkness LLP's ("C&H") recommended negotiation strategy for the bilateral Advance Pricing Agreement ("APA") to be pursued on behalf of Halcyon Semiconductor Inc. ("HSI," EIN 84-2917630) and its parent, Halcyon Semiconductor AG ("HSAG," Steuernummer 203/118/04527), with the Internal Revenue Service Advance Pricing and Mutual Agreement Program ("IRS APMA") and, through the bilateral competent authority mechanism under Article 25 of the US-Germany Income Tax Treaty, the German Bundeszentralamt für Steuern ("BZSt").
The formal APA application — consisting of IRS Form 14661 (Advance Pricing Agreement Request) and all supporting economic analyses, functional analyses, intercompany agreements, and financial documentation — is targeted for filing with IRS APMA on July 7, 2025. The parallel German APA application, to be prepared and submitted by our coordinating German counsel, Kettner Pflüger Rechtsanwälte, is targeted for submission to the BZSt on August 15, 2025. This staggered filing approach is consistent with standard bilateral APA practice and allows sufficient time for coordination between the US and German applications.
The bilateral APA will seek coverage for three categories of covered intercompany transactions between HSAG and HSI:
(a) Tangible Goods (Wafer/Die Sales): Intercompany sales of semiconductor wafers and die from HSAG to HSI under the Master Intercompany Supply Agreement;
(b) Royalties (IP License): Royalty payments from HSI to HSAG under the IP License Agreement for the right to use HSAG's proprietary semiconductor process technology, design libraries, and related intangible property; and
(c) Cost-Sharing Contributions (R&D CSA): HSI's cost-sharing payments under the Qualified Cost Sharing Arrangement for the joint development of next-generation semiconductor process technology.
The proposed APA term encompasses five prospective tax years (January 1, 2025 through December 31, 2029), together with a rollback request covering three prior tax years (January 1, 2022 through December 31, 2024), for a total covered period of eight tax years. This eight-year coverage period is intended to provide meaningful transfer pricing certainty for both HSAG and HSI across the full spectrum of intercompany transactions and to eliminate the risk of double taxation on approximately €1.28 billion in annual aggregate intercompany flows.
This memorandum addresses the following strategic elements of the bilateral APA negotiation:
(a) Our proposed opening positions for each of the three covered transaction categories, including the transfer pricing methods, profit level indicators, benchmarking results, and proposed arm's-length ranges;
(b) Anticipated pushback scenarios from IRS APMA and the BZSt, drawing on our experience with semiconductor industry APAs, the specific feedback received during the pre-filing conference with IRS APMA held on May 19, 2025, and informal intelligence from Kettner Pflüger regarding BZSt expectations;
(c) Defined fallback and concession parameters for each transaction, including hard floors and ceilings beyond which we should not concede without further client authorization;
(d) Critical assumption design — the factual predicates that will underpin the APA and the negotiation strategy for ensuring that the critical assumption set is sufficiently broad to accommodate the inherent cyclicality of the semiconductor industry without being so narrow as to create premature cancellation triggers; and
(e) Overall strategy for managing the bilateral negotiation dynamic between IRS APMA and the BZSt, including coordination protocols with Kettner Pflüger, timeline expectations, and internal consistency analysis across the three covered transactions.
Throughout this memorandum, we reference the pre-filing conference with IRS APMA held on May 19, 2025, and the summary memorandum prepared by Leila Nazari following that conference (the "Pre-Filing Conference Memorandum," dated May 22, 2025, Matter No. 1032-00006, Bates Nos. SC-PF-0001 through SC-PF-0019), which captured the IRS's preliminary feedback and areas of focus. The pre-filing conference was attended by Leonard Cross, Leila Nazari, and Dr. Annika Breitner (Meridian Economics GmbH), on behalf of the applicants, and by IRS APMA Team Leader Jennifer Liu and Senior Economist Mark Holloway, on behalf of the Service.
II. Background Summary
A. Parties and Relationships
Halcyon Semiconductor AG ("HSAG") is a German Aktiengesellschaft publicly listed on the Frankfurt Stock Exchange (XETRA: HSA; ISIN DE000HSA0017). HSAG's registered office is located at Halcyon-Allee 12, 01099 Dresden, Saxony, Germany. HSAG is the ultimate parent entity of the Halcyon group and serves as the group's primary research and development center, intellectual property owner, and semiconductor manufacturer.
HSAG designs and manufactures advanced-node semiconductor wafers across three process technology generations — 7nm, 5nm, and 3nm — at fabrication facilities in the German states of Saxony and Chemnitz. Specifically, HSAG operates Fab 1 and Fab 2 at the Industriepark Klotzsche in Dresden, and Fab 3 at the Technologiepark Chemnitz. These fabrication facilities represent billions of euros in cumulative capital investment and employ highly specialized engineering and manufacturing personnel. HSAG is also engaged in the development of next-generation 2nm and sub-2nm process technologies at its advanced research center co-located at the Dresden campus.
For the fiscal year ended December 31, 2024 ("FY 2024"), HSAG reported consolidated revenue of €8.74 billion, EBITDA of €2.62 billion (representing a 30.0% EBITDA margin), and EBIT of €1.57 billion (representing an 18.0% EBIT margin). HSAG employs approximately 22,400 persons globally, of which approximately 14,600 are based in Germany. The group's senior management team includes: Dr. Klaus-Dieter Wehrheim (Chief Executive Officer), Margarethe Stein (Chief Financial Officer), Dr. Erwin Fassbinder (Senior Vice President, Group Tax), and Dr. Hendrik Möller (Chief Technology Officer).
Halcyon Semiconductor Inc. ("HSI") is a Delaware C-corporation and a wholly owned subsidiary of HSAG. HSI serves as the exclusive United States distributor, marketing entity, and design-support operation for Halcyon products in the North American market. HSI's principal office is located at 8700 Parmer Lane, Building 4, Austin, Texas 78729. HSI also maintains a design center at 2455 Augustine Drive, Suite 300, Santa Clara, California 95054, and regional sales offices in Southfield, Michigan and Beaverton, Oregon. The Austin office houses HSI's executive team, finance, supply chain management, and customer service operations. The Santa Clara design center provides application-specific design support to HSI's major customers, including layout optimization, performance characterization, and customer integration services.
For FY 2024, HSI reported revenue of $4.12 billion in third-party US sales, cost of goods sold ("COGS") of $3.38 billion, and operating income of $197.8 million, representing an operating margin of 4.80%. HSI employs approximately 2,850 persons. HSI's senior management team includes: Victor Almeida (President), Priya Raghavan (Vice President, Tax), and Thomas Kuroda (Vice President, Supply Chain).
Affiliated entities not within the scope of the APA include Halcyon Semiconductor Japan K.K. ("HSJ," based in Tokyo) and Halcyon Semiconductor (Shanghai) Co., Ltd. ("HSC," based in Shanghai). HSJ and HSC serve as distribution and customer support entities for the Japanese and Greater China markets, respectively. While HSAG has intercompany transactions with both HSJ and HSC, these transactions are addressed through separate local transfer pricing documentation and are not included in the bilateral APA request. To the extent that IRS APMA inquires about these entities during the examination phase, we should be prepared to describe their functional profiles and confirm that their transfer pricing is managed independently.
B. Covered Transactions and Aggregate Intercompany Flows (FY 2024)
The bilateral APA covers three categories of intercompany transactions between HSAG and HSI. The aggregate annual intercompany flows across these three categories are substantial, totaling approximately €1.28 billion (approximately $1.39 billion) for FY 2024. Each covered transaction is described below with relevant financial details.
1. Tangible Goods (Wafer/Die Sales): HSAG to HSI
Under the Master Intercompany Supply Agreement (originally effective January 1, 2019; amended July 1, 2022, to reflect updated pricing terms and product specifications), HSAG manufactures and sells semiconductor wafers and die to HSI for resale to third-party customers in the North American market. HSI purchases finished wafers and die on an FOB shipping point basis from HSAG's Dresden and Chemnitz fabrication facilities. HSI bears inventory risk from the point of shipment and extends credit terms to its third-party customers. The intercompany transfer price is set on a quarterly basis using an internal pricing formula tied to standard cost plus a markup, subject to annual true-up.
For FY 2024, intercompany tangible goods sales from HSAG to HSI totaled €987.6 million (approximately $1.076 billion at the FY 2024 average EUR/USD exchange rate of 1.0896). This represents the single largest intercompany flow between HSAG and HSI and constitutes approximately 77% of total aggregate intercompany flows.
2. Royalties (IP License): HSI to HSAG
Under the IP License Agreement (effective January 1, 2019), HSAG licenses to HSI the right to use HSAG's proprietary semiconductor process technology, design libraries, process design kits ("PDKs"), and related intangible property for the purpose of marketing and selling Halcyon products in the North American market. The license is exclusive to HSI within the United States and non-exclusive elsewhere. HSI pays HSAG a running royalty calculated as 6.0% of HSI's IP-attributable revenues. The IP-attributable revenue base is defined in the IP License Agreement as the portion of HSI's net third-party revenues that are directly attributable to the use of HSAG's licensed intangible property, as determined by a revenue attribution methodology set forth in Schedule B to the agreement.
For FY 2024, royalty payments from HSI to HSAG totaled €68.4 million (approximately $70.5 million at the weighted average payment-date EUR/USD exchange rate of 1.0307). HSI's IP-attributable revenue base for FY 2024 was $745.7 million, representing approximately 18.1% of HSI's $4.12 billion in total net revenues.
3. Cost-Sharing Contributions (R&D CSA): HSI to HSAG
Under the Qualified Cost Sharing Arrangement ("CSA," effective July 15, 2018), HSAG and HSI jointly bear the costs of developing next-generation semiconductor process technology, specifically 2nm and sub-2nm process R&D. HSI's cost-sharing percentage is 22.5%, reflecting the proportion of total anticipated benefits from the jointly developed intangible property that is attributable to exploitation in the North American market (HSI's designated territory under the CSA).
At inception of the CSA on July 15, 2018, HSI made a Platform Contribution Transaction ("PCT") buy-in payment of $312.5 million to HSAG to compensate HSAG for making its pre-existing semiconductor process technology platform available as a foundation for the joint R&D activities. The PCT was valued by Stonebridge Valuation Partners LLC (Marcus Reinhardt, Managing Director; office at 200 Park Avenue, Suite 1510, New York, NY 10166), using the income method with a discount rate of 11.8% and a 15-year projection period, consistent with the requirements of Treas. Reg. § 1.482-7(g)(4).
For FY 2024, total qualified R&D costs under the CSA were €998.2 million (a subset of HSAG's total R&D expenditure of €1.42 billion; the difference reflects R&D activities outside the scope of the CSA, such as maintenance R&D for existing process nodes). HSI's share was €224.6 million (22.5% × €998.2 million), or approximately $231.3 million at the applicable exchange rate.
4. Aggregate Intercompany Flows (FY 2024)
The aggregate annual intercompany flows for FY 2024 across the three covered transaction categories are summarized below:
The substantial scale of these intercompany flows — approximately €1.28 billion annually — underscores the importance of obtaining bilateral APA coverage to provide transfer pricing certainty and eliminate double taxation risk.

D. Key Legal and Regulatory Framework
The bilateral APA will be governed by the following legal and regulatory framework:
Treaty Basis: The bilateral APA is pursued under Article 25 (Mutual Agreement Procedure) of the Convention between the United States of America and the Federal Republic of Germany for the Avoidance of Double Taxation and the Prevention of Fiscal Evasion with Respect to Taxes on Income and Capital and to Certain Other Taxes, signed June 29, 2006 (the "US-Germany Income Tax Treaty"). Article 25(3) specifically authorizes the competent authorities to resolve difficulties or doubts arising as to the interpretation or application of the Treaty and to consult together to eliminate double taxation in cases not provided for in the Treaty.
US Procedural Authority: Revenue Procedure 2015-41, 2015-35 I.R.B. 263, which sets forth the requirements, procedures, and general guidelines for APAs administered by IRS APMA, including procedures for bilateral and multilateral APAs, rollback provisions, and critical assumption frameworks.
US Substantive Standards: IRC § 482 and the regulations thereunder, including: Treas. Reg. § 1.482-1 (general principles and arm's length standard); Treas. Reg. § 1.482-3 (methods for determining taxable income in connection with a transfer of tangible property); Treas. Reg. § 1.482-4 (methods for determining taxable income in connection with a transfer of intangible property); Treas. Reg. § 1.482-5 (comparable profits method); Treas. Reg. § 1.482-6 (profit split method); Treas. Reg. § 1.482-7 (methods to determine taxable income in connection with a cost sharing arrangement); and Treas. Reg. § 1.482-9 (methods to determine taxable income in connection with a controlled services transaction). In addition, Treas. Reg. § 1.6662-6 governs transfer pricing penalty considerations and reasonable cause/good faith defenses, including the penalty protection afforded by an APA.
German Substantive Standards: Section 1 of the Außensteuergesetz ("AStG") (Foreign Tax Act), which sets forth Germany's arm's-length standard for transfer pricing between related parties; Sections 90(3) and 162(3)–(4) of the Abgabenordnung ("AO") (Fiscal Code), which impose documentation requirements for cross-border intercompany transactions; and the Gewinnabgrenzungsaufzeichnungsverordnung ("GAufzV") (Transfer Pricing Documentation Ordinance), which prescribes the form and content of transfer pricing documentation in Germany.
OECD Guidance: The OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations (2022 edition), which both the IRS and BZSt reference as interpretive guidance in applying the arm's-length standard. The OECD Guidelines provide authoritative commentary on the selection and application of transfer pricing methods, comparability analysis, and the treatment of intangibles and cost contribution arrangements.
E. Pre-Filing Conference Takeaways (May 19, 2025)
As summarized in the Pre-Filing Conference Memorandum dated May 22, 2025, the pre-filing conference with IRS APMA on May 19, 2025 yielded the following key observations:
General receptivity. IRS APMA expressed general receptivity to the bilateral approach and the proposed APA term (five prospective years plus three rollback years). Team Leader Jennifer Liu confirmed that APMA has resources available to handle a bilateral APA of this scope and complexity and did not raise any threshold objections to the proposed covered transactions or the bilateral structure. This is a positive indicator of the Service's willingness to engage constructively with the application.
CUT comparability concern. IRS APMA raised questions regarding the comparability of the uncontrolled license agreements used to benchmark the royalty rate. Senior Economist Mark Holloway specifically noted concern about technology vintage — whether certain comparable license agreements involve older or more mature semiconductor IP that may not be reasonably comparable to HSAG's cutting-edge 3nm/5nm/7nm process technology — and geographic scope — whether certain CUT agreements involve worldwide or multi-jurisdictional licenses as opposed to the US-only scope of the HSAG-HSI license. Mr. Holloway indicated that the IRS would expect detailed comparability analysis for each comparable agreement. This feedback is significant and is addressed in detail in Section IV below.
PCT valuation methodology. IRS APMA requested additional detail on the CSA Platform Contribution Transaction ("PCT") valuation methodology and the underlying assumptions used in the 2018 Stonebridge Valuation Partners income method analysis. Ms. Liu indicated that the IRS would expect to review the complete valuation report, including the discount rate derivation, the revenue and cost projection inputs, and the basis for the 15-year projection period. This area of focus is addressed in detail in Section V below.
Rollback consistency. IRS APMA expressed standard interest in the feasibility of the rollback request and, specifically, the consistency between the proposed APA methodology and HSI's filed return positions for the three rollback tax years (2022, 2023, and 2024). Ms. Liu indicated that rollback would be considered only if the APA terms are consistent with the transfer pricing positions reflected on HSI's original tax returns for those years, and that any inconsistencies would need to be reconciled through amended returns.
CPM/TNMM acceptance. IRS APMA did not raise any outright objections to the proposed use of the Comparable Profits Method ("CPM") / Transactional Net Margin Method ("TNMM") for the tangible goods transaction with HSI as the tested party. This is consistent with our expectation, as the CPM/TNMM with the US distributor as tested party is a well-established methodology in the semiconductor industry and has been accepted by IRS APMA in numerous prior APAs.
III. Negotiation Strategy — Tangible Goods (Wafer/Die Sales)
A. Proposed Opening Position
The tangible goods transaction — intercompany sales of semiconductor wafers and die from HSAG to HSI — is the largest of the three covered intercompany flows, representing approximately 77% of total aggregate intercompany transactions. The transfer pricing methodology and arm's-length range for this transaction will have the most direct and significant impact on the allocation of taxable income between the United States and Germany.
Transfer Pricing Method. We propose the Transactional Net Margin Method ("TNMM") as described in Chapter II of the OECD Transfer Pricing Guidelines (2022 ed.), which corresponds to the Comparable Profits Method ("CPM") under Treas. Reg. § 1.482-5. The TNMM/CPM is the most reliable method for this transaction because: (i) HSI performs limited-risk distribution functions that are well-benchmarked against comparable independent distributors; (ii) the intercompany tangible goods are not subject to reliable CUP analysis due to the proprietary and highly differentiated nature of HSAG's semiconductor products; and (iii) the resale price method is difficult to apply reliably because there are no comparably situated semiconductor distributors purchasing identical products from unrelated suppliers. The selection of TNMM/CPM is consistent with the "best method rule" under Treas. Reg. § 1.482-1(c) and with the hierarchy-neutral approach of the OECD Guidelines.
Tested Party. HSI is proposed as the tested party for the TNMM/CPM analysis. HSI is the least complex entity in the controlled transaction and the entity for which the most reliable comparable data can be identified. HSI functions as a limited-risk distributor: it performs distribution, marketing, application-specific design support, and customer service functions; it holds limited intangible property (principally customer relationships and marketing know-how developed in the ordinary course of distribution activities); it bears inventory risk (from FOB shipping point) and credit risk (extending payment terms to third-party customers); but it does not bear significant market risk, technology risk, or manufacturing risk. HSAG, by contrast, is the complex, IP-rich manufacturer and developer with significant unique and valuable intangible property, making it a poor candidate for TNMM/CPM testing due to the lack of reliable comparables.
Profit Level Indicator ("PLI"). The proposed PLI is operating margin on net third-party resales (operating income divided by net revenue from third-party sales). Operating margin is the most commonly used PLI for distribution entities and provides a reliable measure of the distributor's routine return for its distribution functions and risks. We considered, and rejected, the Berry ratio (gross profit divided by operating expenses) as the primary PLI because HSI's operating expenses include significant cost elements (SG&A, design support center costs, and allocated CSA contributions) that are not proportional to its distribution intensity, making the Berry ratio a less reliable indicator. We also considered, and rejected, return on assets because HSI's asset base includes significant intercompany receivables and inventory holdings that create comparability challenges with the benchmark set.
Benchmark Set. Meridian Economics GmbH conducted a comprehensive benchmarking search using the Fenmore Services Inc. database, supplemented by SEC filing review, to identify comparable North American semiconductor distributors. After applying quantitative and qualitative screening criteria — including industry classification (SIC codes 5065 and 5045, supplemented by NAICS 423690 and 423430), functional comparability (distribution, marketing, limited or no manufacturing, limited or no proprietary IP), geographic focus (primarily North American operations), size criteria (annual revenue of $100 million to $15 billion), and data availability (at least three years of audited financial data) — Meridian identified a final set of 17 comparable companies. Financial data for these companies was collected for fiscal years 2020 through 2024, providing a five-year data window that captures a full semiconductor industry cycle (including the COVID-19 demand surge of 2020–2021, the supply chain disruptions of 2022, the inventory correction of 2023, and the AI-driven recovery of 2024).
Proposed Arm's-Length Range (Interquartile Range). Based on the five-year weighted average operating margins of the 17 comparable companies, the interquartile range ("IQR") is:
• 25th percentile: 2.8% operating margin
• Median (50th percentile): 4.4% operating margin
• 75th percentile: 6.1% operating margin
HSI's Actual Result. HSI's FY 2024 operating margin was 4.80%, which falls within the IQR and is slightly above the median of 4.4%. HSI's operating margins for the three rollback years were: FY 2022: 3.92%; FY 2023: 4.15%; FY 2024: 4.80%. All three years fall within the proposed IQR, and the three-year weighted average (FY 2022–2024) of approximately 4.31% is also within range and close to the median.
Opening Position. Our opening position is that the full interquartile range of 2.8% to 6.1% should be accepted as the arm's-length range for purposes of the APA, and that HSI's results should be tested against this range on a multi-year weighted average basis (specifically, a three-year rolling weighted average). As long as HSI's three-year rolling weighted average operating margin falls within the IQR, no adjustment should be required. If the three-year rolling weighted average falls outside the IQR, HSI would make a compensating adjustment to bring its result to the median (4.4%).
B. Anticipated IRS Pushback Scenarios
Based on our experience with IRS APMA in semiconductor industry APAs and the pre-filing conference feedback, we anticipate the following areas of IRS pushback on the tangible goods transaction:
1. Narrowing the range. IRS APMA frequently seeks a narrower arm's-length range than the full IQR, or alternatively, proposes a single-point target with a tolerance band. We should expect the IRS to propose collapsing the arm's-length range to a narrower band centered around the median — for example, 3.5% to 5.5% operating margin, or even tighter. There is also a meaningful possibility that the IRS will insist on a single-point target (the median of 4.4%) with a defined tolerance band (e.g., ±0.5 or ±1.0 percentage points), rather than accepting the full IQR as the arm's-length range. In bilateral APAs, point targets with tolerance bands are somewhat more common than full IQR ranges, because they simplify the bilateral negotiation and reduce the scope for disputes during the compliance phase.
2. Comparable selection challenges. IRS APMA will conduct its own review of the 17-comparable set and may challenge the inclusion or exclusion of specific companies. We should anticipate that the IRS will issue Information Document Requests ("IDRs") seeking the detailed financial statements, segment data, and business descriptions for each comparable company, as well as a complete description of Meridian's screening methodology, including the precise quantitative filters applied at each stage and the qualitative reasons for any manual exclusions. The IRS may argue that certain comparables are not sufficiently similar in terms of product mix (e.g., distributors of commodity semiconductor components versus advanced-node wafers), customer concentration, or risk profile. Conversely, the IRS may propose the inclusion of additional companies that Meridian excluded, potentially broadening or shifting the range.
3. Single-year versus multi-year testing. IRS APMA may prefer annual compliance testing rather than the multi-year rolling weighted average that we propose. Annual testing is administratively simpler from the IRS's perspective and ensures that the arm's-length standard is satisfied in each tax year. However, annual testing creates significant volatility risk in the semiconductor industry, where operating margins can fluctuate substantially from year to year due to cyclical demand patterns, inventory dynamics, foreign exchange movements, and new product introduction timing. If FY 2023's industry-wide inventory correction had depressed HSI's margin below the floor in a single year, annual testing would have required an adjustment even though the multi-year average remained well within range.
4. Alternative profit level indicator. While operating margin is our proposed PLI, the IRS may suggest a Berry ratio (gross profit divided by operating expenses) or return on operating assets as a cross-check or alternative PLI. The Berry ratio may be raised particularly if the IRS questions the reliability of operating margin for distributors carrying significant inventory — the argument being that inventory-intensive distributors may have low operating margins even when earning an adequate return on their invested capital. Return on assets may be proposed if the IRS views HSI's working capital investment (receivables, inventory) as a significant risk factor warranting asset-based return analysis. We should be prepared to address these alternatives, though we believe operating margin is the most reliable PLI for the reasons stated above.
5. Comparability adjustments. IRS APMA routinely requests comparability adjustments to the benchmark set to improve the reliability of the comparison. The most commonly requested adjustments include: (a) working capital adjustments to account for differences in accounts receivable, inventory, and accounts payable levels between HSI and the comparable companies; (b) accounting consistency adjustments to normalize for differences in depreciation methods, revenue recognition policies, or expense classification; and (c) risk adjustments to account for differences in the risk profiles of the comparable companies relative to HSI. Meridian Economics has pre-computed working capital adjustments to the comparable set; these adjustments shift the IQR upward by approximately +0.2% to +0.4% (i.e., the adjusted IQR would be approximately 3.0% to 6.5%).
6. BZSt coordination — tested party selection. While IRS APMA is unlikely to propose HSAG as the tested party (as this would be inconsistent with standard US practice for limited-risk distributor APAs), the BZSt may prefer TNMM analysis with HSAG as the tested party, which is more consistent with German transfer pricing documentation practice under the GAufzV. If the BZSt independently advocates for HSAG as the tested party during the competent authority negotiations, this would create a fundamental methodological divergence between the US and German positions that could significantly complicate the bilateral process. We must manage this risk proactively through close coordination with Kettner Pflüger to ensure that the German APA application presents HSI as the tested party from the outset, or at minimum, presents HSAG-tested-party analysis only as a corroborative cross-check.
C. Fallback Positions and Concession Parameters
Our concession strategy for the tangible goods transaction is structured in tiers, with clearly defined floors and ceilings:
Primary concession. We are willing to accept a tighter interquartile range centered around the median of 4.4%. An acceptable narrowed range would be approximately 3.5% to 5.5% operating margin. This range still encompasses HSI's FY 2024 actual result of 4.80% and provides sufficient breathing room for cyclical fluctuations. Importantly, the 3.5% floor would not have been breached in any of the rollback years (FY 2022: 3.92%; FY 2023: 4.15%), providing consistency across the entire proposed APA coverage period.
Secondary concession. If IRS APMA insists on a point estimate with a tolerance band rather than a range, we propose a target of 4.4% (the median) with a tolerance band of ±1.0 percentage point (i.e., an effective range of 3.4% to 5.4%), tested on a three-year rolling weighted average basis. The three-year rolling average testing mitigates the year-to-year volatility that would otherwise make a point-target approach unworkable in the semiconductor industry. If the three-year rolling weighted average falls outside the tolerance band, HSI would make a compensating adjustment to bring its result to the target (4.4%).
Hard floor. We should not accept a range or target that would result in HSI's operating margin falling below 2.5% in any given year or on a multi-year average basis. An operating margin below 2.5% is inconsistent with HSI's functions and risks as a limited-risk distributor performing distribution, marketing, design support, and customer service activities. A margin below this level would imply that HSI is earning less than its routine return, allocating an unreasonable share of residual profit to HSAG. Moreover, a target or range floor below 2.5% would almost certainly not be accepted by the BZSt, as it would imply an excessive allocation of US taxable income to HSAG's account. If the IRS proposes a range floor below 2.5%, we should request a recess and consult with the client before responding.
Hard ceiling. We should not accept a range or target with an upper bound above 7.0%. An operating margin above 7.0% would allocate excessive residual profit to HSI relative to its limited functions, assets, and risks, and would correspondingly reduce HSAG's German taxable income. This would create strong German competent authority resistance and could jeopardize the bilateral APA. The 7.0% ceiling also exceeds the 75th percentile of the benchmark set (6.1%), making it difficult to support from an economic analysis perspective.
Multi-year versus single-year testing. We strongly prefer three-year rolling weighted average testing given the inherent cyclicality of the semiconductor industry. If IRS APMA insists on annual testing, we should seek a compensating/year-end adjustment mechanism that allows HSI to bring its results within range through a year-end transfer price adjustment, rather than a structure in which a single-year deviation from the range constitutes a compliance failure triggering penalties or APA cancellation. The compensating adjustment should be due within 90 days of the filing of HSI's federal income tax return for the applicable year.
Working capital adjustments. We are prepared to accept reasonable working capital adjustments to the comparable set. Meridian Economics has pre-computed adjusted results for all 17 comparables using the standard working capital adjustment methodology (adjusting for differences in accounts receivable, inventory, and accounts payable levels, using the one-year Treasury bill rate as the imputed financing cost). These adjustments shift the IQR upward by approximately +0.2% to +0.4%, which would nominally benefit our position by raising the comparable range. However, we should be aware that the IRS may apply its own working capital adjustment methodology that yields different results. We are comfortable defending our adjustment methodology, as it is based on standard industry practice and has been accepted by IRS APMA in prior engagements.
D. Tactical Considerations
Several tactical considerations should guide our approach to the tangible goods negotiation:
Lead with HSI's characterization. The strength of our position rests on the characterization of HSI as a limited-risk distributor — an entity that performs routine distribution, marketing, design support, and customer service functions; holds limited intangible property; and bears limited risk relative to the principal/entrepreneur entity (HSAG). This characterization is well-established in IRS case law (including Harborview Corporation, Inc. v. Commissioner, T.C. Memo. 2016-112, and subsequent proceedings), the Treasury Regulations, and the OECD Guidelines. We should lead with a compelling functional analysis that clearly delineates HSI's limited functions, assets, and risks from HSAG's entrepreneurial activities.
Emphasize benchmark robustness. The 17-comparable set represents a robust and well-screened benchmark for North American semiconductor distributors. The five-year data window (FY 2020–2024) captures a full industry cycle, reducing the impact of cyclical distortions. We should emphasize the consistency of the screening methodology, the breadth of the comparable set (17 companies is a strong sample size for semiconductor distribution), and the stability of the IQR across the five-year data period.
Resist HSAG as tested party. If the IRS — or, more likely, the BZSt through the competent authority process — proposes HSAG as the tested party, we should resist firmly. HSAG is the complex, IP-rich entity with significant unique and valuable intangible property (proprietary semiconductor process technology, design libraries, patents, trade secrets, and accumulated manufacturing know-how). Testing HSAG would require either a comparable profit split or a residual profit split analysis, both of which introduce substantially more subjectivity and are more difficult to benchmark reliably. The use of HSAG as tested party would also be inconsistent with the overwhelming weight of IRS APMA practice for limited-risk distributor structures in the semiconductor industry.
Coordinate with Kettner Pflüger on tested party. It is essential that we coordinate with Dr. Tobias Kettner and Friederike Lang at Kettner Pflüger to ensure that the BZSt does not independently advocate for HSAG as the tested party during the competent authority negotiations. If the BZSt takes a position that HSAG should be tested, and the IRS has already accepted HSI as the tested party, this would create a bilateral impasse that could significantly delay APA execution. Dr. Kettner should be advised to present the German APA application with HSI as the tested party, or at minimum, with an HSAG-tested analysis presented only as a corroborative cross-check rather than a primary methodology.
IV. Negotiation Strategy — Royalties (IP License)
A. Proposed Opening Position
The royalty transaction — HSI's payment to HSAG for the right to use HSAG's proprietary semiconductor process technology, design libraries, and related intangible property — is the covered transaction most likely to generate significant IRS scrutiny, based on the feedback received during the pre-filing conference. The royalty pricing directly affects the allocation of returns from intellectual property between the United States and Germany and therefore implicates the core transfer pricing policy interests of both IRS APMA and the BZSt.
Transfer Pricing Method. We propose the Comparable Uncontrolled Transaction ("CUT") method under Treas. Reg. § 1.482-4(c) as the primary transfer pricing method for the royalty transaction, corroborated by a residual profit split analysis under Treas. Reg. § 1.482-6 as a secondary method. The CUT method is the most direct application of the arm's-length standard for intangible property licensing transactions and is generally regarded as the most reliable method when sufficiently comparable uncontrolled transactions can be identified. The residual profit split analysis serves as a confirmation that the royalty, in combination with the other intercompany prices, produces an economically coherent allocation of total profits between HSAG and HSI that is consistent with each party's relative contributions.
Tested Transaction. The tested transaction is HSI's royalty payment to HSAG for the right to use HSAG's proprietary semiconductor process technology, design libraries, process design kits, and related intangibles in connection with the marketing and sale of Halcyon products in the North American market.
Benchmark Set. Meridian Economics GmbH conducted a comprehensive search for comparable uncontrolled license agreements involving semiconductor intellectual property. The search utilized two primary sources: (i) the Clearpoint Royalty Database (a subscription database maintained by Meridian Economics), which contains detailed information on technology licensing agreements filed with the SEC, reported in patent litigation, or otherwise publicly available; and (ii) a supplemental review of SEC filings (10-K, 10-Q, 8-K, and proxy statements) of publicly traded semiconductor companies that disclosed royalty rates in connection with licensing transactions. After applying comparability screening criteria — including industry (semiconductor), type of IP (process technology, design libraries), payment structure (running royalty based on revenue), licensee function (distribution, marketing, design support), and date range (agreements executed or renewed after 2010) — Meridian identified a final set of eight comparable uncontrolled license agreements.
Proposed Arm's-Length Range (IQR). Based on the royalty rates observed in the eight CUT agreements, the interquartile range is:
• 25th percentile: 3.5% royalty rate on IP-attributable revenues
• Median (50th percentile): 5.6% royalty rate on IP-attributable revenues
• 75th percentile: 8.2% royalty rate on IP-attributable revenues
HSAG's Contractual Rate. The contractual royalty rate under the HSAG-HSI IP License Agreement is 6.0% on IP-attributable revenues, which falls within the IQR and is positioned slightly above the median of 5.6%.
Opening Position. Our opening position is that the 6.0% royalty rate is arm's length, as supported by the full CUT IQR of 3.5% to 8.2%. The 6.0% rate is well-established in the IP License Agreement (effective since January 1, 2019), has been consistently applied across all tax years including the rollback period, and falls within the range of rates observed in comparable arm's-length license agreements. We submit that the full IQR should be accepted as the arm's-length range, with the 6.0% contractual rate confirmed as the specific rate for purposes of the APA.
B. Anticipated IRS Pushback Scenarios
Based on the pre-filing conference feedback and our experience with IRS scrutiny of semiconductor IP royalties, we anticipate the following areas of IRS pushback:
1. CUT comparability challenges. As expressly flagged at the pre-filing conference, IRS Senior Economist Mark Holloway raised concerns about the comparability of certain CUT agreements in the benchmark set. Two specific dimensions of comparability concern were identified. First, technology vintage: certain of the eight CUT agreements may involve licensing of older or more mature semiconductor process technologies (e.g., 28nm or 14nm node technology) that may not be reasonably comparable to HSAG's cutting-edge 3nm, 5nm, and 7nm process technology. The IRS may argue that licenses for more advanced technology should command higher royalty rates, reflecting the greater R&D investment and market value of the underlying IP. Second, geographic scope: certain CUT agreements may involve worldwide or multi-jurisdictional licenses, whereas the HSAG-HSI license is limited to the US market. The IRS may argue that a US-only license should command a lower rate (reflecting a smaller territory) or, conversely, a higher rate (reflecting the premium value of the US market for semiconductor products). The direction of the IRS's geographic scope argument is difficult to predict and may depend on the specific CUTs under discussion.
2. Narrowing the CUT range. IRS APMA may seek to exclude certain CUTs from the benchmark set, particularly those at the extremes of the range (the 3.5% low outlier and the 8.2% high outlier), thereby tightening the IQR. If the IRS successfully challenges the comparability of the extreme observations, the resulting narrowed IQR could shift the median and alter the arm's-length positioning of the 6.0% contractual rate. We should be prepared for a scenario in which the IRS argues for a benchmark set of five or six CUTs (rather than eight), with a correspondingly tighter range.
3. Preference for profit-based corroboration. IRS APMA may insist on greater reliance on the residual profit split analysis as a primary (rather than merely corroborative) method, particularly if CUT comparability is successfully challenged. The IRS has increasingly favored profit-based methods for intangible property transactions involving unique and valuable IP, following the OECD's 2017 BEPS guidance on hard-to-value intangibles (Chapter VI of the OECD Guidelines). If the IRS determines that none of the CUT agreements is sufficiently comparable to serve as a reliable benchmark, the IRS may propose that the residual profit split be elevated to the primary method, with the CUTs serving only as a corroborative cross-check.
4. IP-attributable revenue base. The royalty is computed on HSI's IP-attributable revenues ($745.7 million in FY 2024, representing 18.1% of HSI's $4.12 billion in net revenues). The IRS may challenge the computation of the IP-attributable revenue base — specifically, the revenue attribution methodology set forth in Schedule B to the IP License Agreement. If the IRS contends that a broader share of HSI's revenues is attributable to HSAG's licensed IP (e.g., arguing that the IP-attribution ratio should be 25% or 30% rather than 18.1%), the effective royalty burden on HSI increases even at the same nominal rate. An increase in the IP-attribution ratio from 18.1% to 25.0%, for example, would increase the royalty payment from $70.5 million to approximately $97.5 million at the 6.0% rate, a 38% increase. This is a potentially significant area of IRS focus.
5. BZSt position. We anticipate that the BZSt will advocate for a royalty rate at or above 6.0% to ensure adequate compensation to HSAG as the IP owner and developer. HSAG invests approximately €1.42 billion annually in total R&D and is the entity that developed the licensed intangible property through decades of cumulative investment and innovation. From the BZSt's perspective, a royalty rate that under-compensates HSAG for this investment would improperly erode the German tax base. Dr. Kettner has indicated informally that the BZSt will likely push for a rate of 6.0% or higher, which aligns with our opening position and creates a natural tension in the bilateral dynamic that may work in our favor if the IRS pushes the rate downward.
6. Interaction with CSA. IRS APMA may question whether the royalty and the CSA together create a double charge for IP rights — that is, whether HSI is paying both a royalty for existing IP (through the IP License Agreement) and cost shares for future IP (through the CSA) that is duplicative of or overlapping with the licensed technology. This concern arises because the CSA covers development of "next-generation" 2nm and sub-2nm process technology, which builds upon and advances the existing 7nm, 5nm, and 3nm technology that is the subject of the royalty. The IRS may argue that some portion of the royalty compensates HSAG for technology that also serves as the platform for the CSA development activities, resulting in an economic overlap. This concern must be addressed through clear contractual delineation and a detailed technology scope memorandum.
C. Fallback Positions and Concession Parameters
Primary concession. We are willing to accept a royalty rate anywhere within the range of 5.0% to 7.0%. This range brackets the median (5.6%) and our proposed contractual rate (6.0%) and provides room for bilateral negotiation. A rate within this range is defensible under the CUT analysis (within the IQR of 3.5% to 8.2%), consistent with the residual profit split corroboration, and acceptable to both the IRS (which benefits from a lower rate that allocates more income to HSI) and the BZSt (which benefits from a higher rate that compensates HSAG). We do not anticipate that either authority would object to a rate within this range.
Hard floor: 5.0% royalty rate. We should not accept a royalty rate below 5.0%. A rate below 5.0% would be inconsistent with the weight of the CUT evidence, would under-compensate HSAG for its massive IP investment (total R&D of €1.42 billion in FY 2024), and would almost certainly be rejected by the BZSt. A rate below 5.0% would also fall below the median of the CUT benchmark set (5.6%), requiring an affirmative justification for a below-median result that would be difficult to provide given the advanced nature of HSAG's technology.
Soft ceiling: 7.5%. While a royalty rate above 6.0% allocates additional income to Germany and is therefore generally favorable from HSAG's perspective, a rate above 7.5% would begin to squeeze HSI's operating margin below the CPM/TNMM arm's-length range for tangible goods, creating internal consistency issues between the royalty and the tangible goods pricing. Specifically, a 1.0% increase in the royalty rate reduces HSI's operating margin by approximately 0.18 percentage points (based on the IP-attributable revenue base of $745.7 million relative to HSI's total revenues of $4.12 billion). A rate of 7.5% (1.5 percentage points above the contractual 6.0%) would reduce HSI's operating margin by approximately 0.27 percentage points, which alone is manageable, but when combined with potential concessions on the CSA benefit share, could push HSI below the CPM/TNMM floor.
CUT comparability defense. We are prepared to provide detailed additional comparability analysis for each of the eight CUT agreements to address the technology vintage and geographic scope concerns raised by the IRS at the pre-filing conference. Meridian Economics has prepared detailed comparability matrices for each agreement, analyzing: (a) technology vintage (process node generation, date of technology development, remaining useful life); (b) geographic scope (territory covered by the license); (c) exclusivity (exclusive vs. non-exclusive rights); (d) sublicensing rights (right to grant sublicenses); (e) payment terms (running royalty vs. hybrid, minimum royalty obligations); and (f) ancillary rights (access to updates, technical support, derivative works). These matrices will be included in the APA application economic analysis appendix and should demonstrate that the eight CUT agreements, while not identical to the HSAG-HSI license, are sufficiently comparable after reasonable adjustments to provide reliable benchmarks.
IP-attributable revenue base. We maintain the 18.1% IP-attribution ratio as our primary position. This ratio is derived from the revenue attribution methodology in Schedule B to the IP License Agreement, which distinguishes between revenues attributable to HSAG's licensed technology and revenues attributable to HSI's own distribution, marketing, and customer service efforts. If the IRS challenges the 18.1% ratio, we are prepared to present a range analysis showing IP-attribution ratios of 15% to 25% and demonstrating that the 6.0% royalty rate remains arm's length across this range of reasonable revenue base assumptions. At a 15% attribution ratio, the effective royalty (as a percentage of total HSI revenue) would be 0.9%; at a 25% attribution ratio, it would be 1.5%. Both results are within the range observed for comparable semiconductor distributor structures.
Profit split corroboration. The residual profit split analysis prepared by Meridian Economics confirms that the 6.0% royalty, combined with the tangible goods transfer pricing, allocates routine returns to HSI and residual returns to HSAG in a manner consistent with each party's relative contributions of functions, assets, and risks. Specifically, the residual profit split analysis allocates approximately 82% of combined residual profits to HSAG and 18% to HSI, which is directionally consistent with the parties' relative intangible contributions. If the CUT analysis is impaired by comparability challenges, we are prepared to present the residual profit split analysis as a more prominent secondary method — or, if necessary, a co-primary method — to corroborate the royalty rate.
D. Tactical Considerations
The royalty transaction is the area of greatest IRS focus based on the pre-filing conference feedback, and our preparation for this aspect of the negotiation should be correspondingly thorough.
Comparability matrices. The pre-filing conference expressly flagged CUT comparability as a key IRS concern. We should prepare a comprehensive comparability matrix for each of the eight CUT agreements, to be included in the APA application economic analysis appendix. Each matrix should address the technology vintage, geographic scope, exclusivity, sublicensing rights, and payment terms for the CUT agreement and compare these factors to the corresponding terms of the HSAG-HSI license. Where differences exist, the matrix should identify the direction and estimated magnitude of any comparability adjustment.
Method flexibility. We should be prepared to shift from CUT primary / profit split corroborative to residual profit split primary / CUT corroborative if the IRS definitively rejects the reliability of the CUT analysis. This shift can be presented as a pragmatic accommodation of the IRS's concerns, rather than a concession of principle. The key is to ensure that, regardless of which method is designated as "primary," the resulting royalty rate remains within our acceptable range of 5.0% to 7.0%.
Consistency and rollback. The 6.0% royalty rate was established in the IP License Agreement effective January 1, 2019, and has been consistently applied in all tax years since inception, including the three rollback years (2022–2024). This consistency is a significant strength of our position for purposes of the rollback request. We should emphasize to the IRS that the royalty rate has been stable, has been reported on HSI's filed returns, and is supported by contemporaneous transfer pricing documentation.
BZSt alignment. Dr. Kettner has indicated informally that the BZSt will likely push for a royalty rate of 6.0% or higher. This is consistent with our opening position and provides a natural counterweight to any IRS effort to reduce the rate below 6.0%. We should coordinate with Kettner Pflüger to ensure that the German APA application presents a strong defense of the 6.0% rate and that the BZSt's position is communicated to IRS APMA through the competent authority channel at the appropriate time.
Royalty/CSA interaction. To address the potential double-charge concern, we should prepare a detailed delineation memorandum that clearly distinguishes between the intangible property covered by the royalty (pre-CSA technology: existing 7nm, 5nm, and 3nm process technology) and the intangible property covered by the CSA (post-CSA development: next-generation 2nm and sub-2nm process technology). The delineation should be supported by a technology timeline showing the distinct development periods, patent filings, and product generations associated with each set of intangibles.
V. Negotiation Strategy — Cost Sharing Arrangement (R&D CSA)
A. Proposed Opening Position
The Cost Sharing Arrangement is the most technically complex of the three covered transactions and, together with the royalty, is the area of greatest potential IRS scrutiny. The CSA involves both ongoing cost-sharing payments (which are relatively straightforward in principle) and a substantial Platform Contribution Transaction ("PCT") buy-in payment (which involves a complex income-method valuation that IRS APMA has expressly flagged for additional review).
Transfer Pricing Method. We propose the income method for determining anticipated benefit shares, as prescribed by Treas. Reg. § 1.482-7(g)(4). Under the income method, each participant's cost-sharing percentage reflects the proportion of total anticipated economic benefits from the jointly developed intangible property that is attributable to that participant's designated exploitation territory. The income method uses projected revenue and cost data to estimate the present value of each participant's anticipated benefits, with the cost-sharing percentages set equal to each participant's proportionate share of total anticipated benefits.
HSI's Anticipated Benefit Share. HSI's anticipated benefit share under the CSA is 22.5%, reflecting the proportion of total anticipated benefits from the jointly developed intangible property (next-generation 2nm and sub-2nm semiconductor process technology) attributable to exploitation in the North American market — HSI's designated territory under the CSA. The remaining 77.5% of anticipated benefits is attributable to HSAG's exploitation territories (Europe, Middle East, Africa, and Asia-Pacific). The 22.5% share was determined at the inception of the CSA in July 2018, based on a forward-looking analysis of projected revenues, costs, and profitability in each territory over the useful life of the jointly developed intangible property.
Triennial Review. We propose that the anticipated benefit shares be reviewed triennially during the APA term (i.e., at the end of 2027 and again at the end of 2030, if the APA term extends to 2029 plus rollback). If the triennial review reveals that actual results have materially diverged from the projections underlying the benefit share determination — specifically, if the actual benefit share ratio differs from the projected ratio by more than 3.0 percentage points — the parties would adjust the benefit shares prospectively. This mechanism provides flexibility to address shifts in market dynamics while avoiding the instability of annual benefit share recalculations.
Platform Contribution Transaction. At the inception of the CSA on July 15, 2018, HSI made a PCT buy-in payment of $312.5 million to HSAG. This payment compensated HSAG for making its pre-existing semiconductor process technology platform (comprising process technology for nodes at 7nm and above, design libraries, process design kits, accumulated manufacturing know-how, and related intangible property) available as a foundation for the joint R&D activities under the CSA. The PCT was valued by Stonebridge Valuation Partners LLC (Marcus Reinhardt, Managing Director; office at 200 Park Avenue, Suite 1510, New York, NY 10166) using the income method with the following key assumptions:
• discount rate: 11.8% (weighted average cost of capital derived from a comparable companies analysis of publicly traded semiconductor manufacturers, adjusted for the risk profile of the pre-existing platform contributions);
• Projection period: 15 years (reflecting the estimated useful economic life of the pre-existing platform technology as a foundation for next-generation R&D);
• Revenue projections: Based on Halcyon's internal strategic plan as of Q2 2018, with independent reaso
