Hexadite Case
Background
Valuation for transfer pricing and taxation purposes has shifted from a routine compliance exercise into potential future high-stakes litigation. Global tax authorities have increasingly identified technical pitfalls in how multinational enterprises (MNEs) value intercompany transactions. In practice, a variety of commonly observed valuation assumptions are now primary targets for tax authorities’ challenges.
Scrutiny is often most intense when a corporate group undergoes structural changes such as the transfer of Intangible Property (IP) or the relocation of business units. The challenge from tax authorities typically follows a hierarchical approach, beginning with a critique of the valuation methodology itself. Authorities will question whether a Cost, Market, or Income approach (or a hybrid of these) is most appropriate based on the specific facts and circumstances of the case.
Once the methodology is established, the focus shifts to specific components of the financial modeling. This involves a detailed review of the projections and forecast parameters, discount rates, and warranted adjustments, among others.
A Recent Challenge involving Methodology – Some Important Aspects
Tax authorities often favor the Discounted Cash Flow (DCF) method, as its forward-looking nature captures the full scope of future earning potential and therefore, higher taxable value. Conversely, taxpayers generally prefer the Comparable Uncontrolled Price (CUP) method, particularly when a recent market transaction provides a verifiable price point that mitigates the subjectivity inherent in long-term forecasts, albeit there might be a need to adjust those references to the facts of the analyzed transaction.
In fact, even if the methodological framework is agreed upon between the taxpayer and the tax authority, issues will arise in its application. In the Hexadite versus Tel Aviv 3 Tax Assessor (2025) ruling, both parties agreed on using a Comparable Uncontrolled Price (CUP) method with an internal comparable (essentially a precedent transaction approach). However, the central conflict involved its application for valuing the functions, assets, and risks that were transferred to Microsoft following the acquisition of Hexadite (a cybersecurity startup).
The tax authority argued that the market price was merely a starting point (i.e., a base reference warranting upward adjustments) and sought to increase the taxable base by applying a tax gross-up, effectively treating the value as a net value that needed to be increased for future tax liabilities. Furthermore, they argued that “holdback payments” promised to the founders (sellers) were part of the purchase price for the business itself (i.e., negotiated as part of the compensation for transferring the business). Conversely, the taxpayer defended the CUP method, arguing that the acquisition price was an all-inclusive market benchmark and the adjustments over this price were not applicable. The taxpayer maintained that a tax gross-up was economically redundant in a real-world transaction and that the holdbacks were compensation for future labor, or retention bonuses, rather than payments for the business.
The court’s decision provided a middle ground. On the core issues, it supported the methodological framework but ruled in favor of the taxpayer on the gross-up issue, agreeing that when using the market reference, the market price already reflects all economic factors, including taxes (meaning, an after-tax comparison). However, the court sided with the tax authority on the holdbacks; essentially, these payments were negotiated (and set) as part of the purchase agreement, hence they constituted (delayed) payment for the business’s value rather than a deductible operating expense.
