Section 1: Engagement and Scope
1.1 Engagement Overview
Hargrove Forensic Advisory LLC ("Hargrove" or the "Firm") was retained by Calderwood & Harkness LLP ("C&H" or "Calderwood & Harkness") on July 1, 2022, on behalf of Torchlight Mining Corp. ("TMC" or "Torchlight"), to provide forensic economic advisory services in connection with an ongoing criminal antitrust investigation being conducted by the Antitrust Division of the United States Department of Justice ("DOJ"). The retention was effectuated pursuant to a Kovel-letter arrangement, dated June 28, 2022, between Calderwood & Harkness and Hargrove, designed to preserve the protections of the attorney-client privilege and the work-product doctrine over the communications, analyses, and work product generated by Hargrove in the course of this engagement.
The purpose of the engagement is threefold: (1) to conduct an independent economic analysis of pricing patterns in the North American specialty-minerals market, with particular focus on the three product categories that are the subject of the DOJ investigation; (2) to quantify the volume of affected commerce attributable to Torchlight Mining Corp. and its co-conspirators during the alleged conspiracy period; and (3) to support Calderwood & Harkness in its preparation for non-prosecution agreement ("NPA") penalty negotiations with the DOJ Antitrust Division by providing a well-supported analysis of the appropriate monetary penalty that TMC should expect or propose in the course of those negotiations.
Hargrove has worked closely with the Calderwood & Harkness engagement team, led by partner Elaine Forsythe, throughout this engagement. All analyses, conclusions, and recommendations set forth in this report have been prepared at the direction of counsel and are intended solely for use by Calderwood & Harkness and TMC in connection with the DOJ investigation and related proceedings.
1.2 Scope of Analysis
The scope of this analysis encompasses the following elements:
1. Quantification of Affected Commerce. Hargrove has calculated the total volume of affected commerce for three product categories that are the subject of the DOJ investigation: high-purity feldspar, industrial talc, and rare-earth concentrates. The calculation encompasses all U.S. sales revenue generated by all identified participants in the alleged conspiracy during the conspiracy period.
2. Geographic Scope. The analysis is limited to the United States market — specifically, sales of the three product categories to U.S. industrial and chemical-manufacturing customers. Export sales, sales to non-U.S. customers, and sales of products outside the three identified categories are excluded from the affected-commerce calculation.
3. Temporal Scope. The alleged conspiracy period extends from approximately January 2017 through August 2021, a period of approximately four years and eight months. This temporal scope is consistent with the DOJ's investigation parameters as communicated to Calderwood & Harkness and as reflected in the grand jury subpoenas and related correspondence.
4. Participants Under Analysis. The analysis addresses the affected commerce of the following three entities:
(a) Torchlight Mining Corp., through its U.S. subsidiary, Torchlight Mining (U.S.) Inc. ("TMC U.S."), which operates the U.S. Specialty Minerals Division;
(b) Ridgecrest Minerals Inc. ("Ridgecrest"), a Delaware corporation headquartered in Denver, Colorado, and a portfolio company of Marlowe Asset Management Peak Capital Partners LP; and
(c) Pinnacle Earth Resources Ltd. ("Pinnacle"), an Ontario corporation headquartered in Sudbury, Ontario, with U.S. operations based in Salt Lake City, Utah.
5. Penalty Calculation. Hargrove has applied the DOJ Antitrust Division's standard fine-calculation methodology under the United States Sentencing Guidelines framework to derive a base fine for TMC and has analyzed applicable cooperation and remediation credits to arrive at a recommended penalty range and target negotiation figure.
6. Cooperation and Remediation Credits. The analysis includes an assessment of the cooperation and remediation credits that TMC may be entitled to claim in NPA negotiations, based on TMC's cooperation record, remediation efforts, and comparable DOJ precedents.
1.3 Materials Reviewed
In preparing this analysis, Hargrove reviewed and relied upon the following categories of materials and data sources:
• TMC Internal Sales and Revenue Data (FY 2015 – FY 2022). Comprehensive sales revenue data for the U.S. Specialty Minerals Division, including product-level revenue breakdowns for high-purity feldspar, industrial talc, and rare-earth concentrates. This data was extracted from TMC's enterprise resource planning ("ERP") systems and provided to Hargrove through document productions managed by Redstone Digital Forensics Inc. ("Redstone"), under the direction of Calderwood & Harkness. Data integrity was verified through cross-referencing with invoice-level records, customer contract files, and audited financial statements.
• TMC U.S. Specialty Minerals Division Pricing Databases, Customer Contract Files, and Invoice Records. Detailed pricing information, including published price lists, customer-specific negotiated pricing, contract amendments, and historical invoice data for each of the three product categories during the relevant periods.
• Publicly Available Financial Statements for Ridgecrest Minerals Inc. and Pinnacle Earth Resources Ltd. Annual and quarterly financial statements, including 10-K and 10-Q filings (for Ridgecrest) and SEDAR+ filings (for Pinnacle), used to estimate revenue and product-mix data for the co-conspirators.
• DOJ Subpoena Specifications. Subpoena Nos. GJ-22-0194-SD-003 (dated February 14, 2022) and GJ-22-0194-SD-007 (dated May 3, 2023) were reviewed to ensure that the product categories and temporal scope analyzed in this report are aligned with the categories and periods specified by the DOJ in its investigative demands.
• Published Pricing Benchmarks from the North American Specialty Minerals Council ("NASMC"). Industry pricing benchmark indices for high-purity feldspar, industrial talc, and rare-earth concentrates, published quarterly by NASMC, were used as control variables in the pricing correlation analysis described in Section 4 of this report.
• Industry Reports and Market Analyses. Published reports and analyses from recognized industry sources, including market-share studies, demand analyses, and competitive landscape assessments for the North American specialty-minerals sector.
• Calderwood & Harkness Internal Investigation Memoranda and VaultChat Message Analysis. Memoranda prepared by the Calderwood & Harkness internal investigation team, including analyses of VaultChat encrypted messaging exchanges between TMC personnel and personnel at Ridgecrest and Pinnacle. These materials were provided to Hargrove under the protections of the Kovel-letter arrangement and remain subject to privilege.
• Draft Hargrove Expert Report (August 15, 2023). The prior version of this analysis, submitted to the DOJ Antitrust Division on August 22, 2023, as part of TMC's ongoing cooperation efforts. This final report supersedes the August 2023 draft in all respects.
• TMC FY 2021 Annual Report. TMC's consolidated revenue for FY 2021 was approximately CAD 4.27 billion (approximately USD 3.38 billion at prevailing exchange rates). The TMC U.S. Specialty Minerals Division reported FY 2021 revenue of approximately USD 687 million.
A complete list of all documents, databases, filings, and industry sources reviewed in the preparation of this report is set forth in Exhibit F.

Section 2: Background — The Investigation and Alleged Conduct
2.1 Overview of the DOJ Investigation
The DOJ Antitrust Division is conducting a criminal investigation into alleged anticompetitive conduct in the North American specialty-minerals market, under the authority of Grand Jury No. GJ-22-0194, empaneled in the United States District Court for the Northern District of California, San Francisco Division. The investigation was formally opened on or about February 10, 2022, and is ongoing as of the date of this report.
The investigation is led by Trial Attorney Denise Kowalski and Senior Trial Attorney Marcus Reeves of the DOJ Antitrust Division, San Francisco Field Office, under the supervision of Deputy Assistant Attorney General Julia Stafford-Hayes. The investigation is part of the DOJ Antitrust Division's broader enforcement program targeting cartel conduct in commodity and industrial-input markets.
The investigation was triggered by a cooperation agreement entered into on or about September 15, 2021, between Cascade Chemical Supply Co. ("Cascade"), a specialty chemical distributor headquartered in Spokane, Washington, and the DOJ Antitrust Division. Cascade, which was a significant purchaser of high-purity feldspar and industrial talc from TMC and Ridgecrest during the alleged conspiracy period, provided the DOJ with information, documents, and testimony regarding pricing patterns and communications that it observed or received from the alleged conspirators during the relevant period. The Cascade cooperation agreement provided the initial evidentiary foundation for the DOJ's investigation.
The targets and subjects of the investigation, as communicated to Calderwood & Harkness through the grand jury subpoenas and subsequent correspondence, include the following entities:
• Torchlight Mining Corp. ("TMC"), a Canadian corporation headquartered in Vancouver, British Columbia, operating in the United States through its wholly owned subsidiary, Torchlight Mining (U.S.) Inc., which manages the U.S. Specialty Minerals Division.
• Ridgecrest Minerals Inc. ("Ridgecrest"), a Delaware corporation headquartered in Denver, Colorado. Ridgecrest is a portfolio company of Marlowe Asset Management Peak Capital Partners LP, a Denver-based private equity firm. Ridgecrest is one of the largest domestic producers of industrial talc and high-purity feldspar in the United States, with FY 2021 revenue of approximately USD 1.92 billion.
• Pinnacle Earth Resources Ltd. ("Pinnacle"), an Ontario corporation headquartered in Sudbury, Ontario, Canada, with U.S. operations based in Salt Lake City, Utah. Pinnacle is a diversified mining and resources company with significant operations in rare-earth concentrates and industrial minerals, reporting FY 2021 revenue of approximately CAD 1.45 billion (approximately USD 1.15 billion).
TMC received its first grand jury subpoena (Subpoena No. GJ-22-0194-SD-003) on February 14, 2022. A second subpoena (Subpoena No. GJ-22-0194-SD-007) was issued on May 3, 2023, requesting additional categories of documents and data. TMC received a target letter from the DOJ Antitrust Division on May 20, 2022, formally identifying TMC as a target of the investigation.
2.2 Alleged Conduct
The DOJ investigation concerns an alleged agreement among senior commercial personnel at TMC, Ridgecrest, and Pinnacle to fix prices, allocate customers, and rig bids for three categories of specialty minerals — high-purity feldspar, industrial talc, and rare-earth concentrates — sold to U.S. industrial and chemical-manufacturing customers. The alleged conspiracy is a per se violation of Section 1 of the Sherman Act, 15 U.S.C. §1.
The key individuals identified as participants in the alleged conspiracy are:
• Gavin Holt, Former Vice President, U.S. Specialty Minerals Sales, Torchlight Mining (U.S.) Inc. Mr. Holt held this position from approximately March 2015 through his resignation, effective September 30, 2021. Mr. Holt was responsible for overseeing TMC's pricing and sales strategy for all three affected product categories in the U.S. market and had direct authority over published price lists, customer-specific pricing, and bid submissions.
• Carl Edgerton, Vice President of Sales, Ridgecrest Minerals Inc. Mr. Edgerton has held this position since approximately 2014 and was responsible for Ridgecrest's pricing and sales activities in the specialty-minerals segment during the alleged conspiracy period.
• Kevin Tsang, Former Senior Vice President, Commercial Operations, Pinnacle Earth Resources Ltd. Mr. Tsang held this position from approximately 2013 through approximately early 2022. Mr. Tsang was responsible for Pinnacle's U.S. commercial operations, including pricing and customer management for the affected product categories.
The alleged channels of coordination among these individuals included:
(a) In-person meetings at NASMC quarterly conferences. The North American Specialty Minerals Council ("NASMC") holds quarterly conferences that are attended by representatives of major specialty-minerals producers, distributors, and end users. During the alleged conspiracy period, NASMC conferences were held at various locations, including Arlington, Virginia; Scottsdale, Arizona; and Orlando, Florida. According to the Calderwood & Harkness internal investigation, Holt, Edgerton, and Tsang attended overlapping NASMC conferences on at least fourteen occasions during the conspiracy period and were observed in side meetings or informal gatherings outside of official conference programming.
(b) Encrypted messaging via the VaultChat application. The Calderwood & Harkness internal investigation identified at least 37 documented VaultChat encrypted messaging exchanges between Holt and his counterparts at Ridgecrest (Edgerton) and Pinnacle (Tsang) during the period from March 2017 through July 2021. The first documented VaultChat exchange between Holt and Edgerton was on March 14, 2017. The VaultChat application is a commercially available encrypted messaging platform that provides end-to-end encryption and message-deletion features. The use of a dedicated encrypted messaging channel for competitor communications is, in itself, indicative of an intent to conceal the nature and content of those communications from TMC's management and compliance functions.
(c) Occasional phone calls. The Calderwood & Harkness internal investigation identified evidence of phone calls between Holt and Edgerton, and between Holt and Tsang, that occurred in temporal proximity to pricing decisions and bid submissions. While the content of these calls cannot be directly reconstructed, the timing and frequency of the calls are consistent with the coordination patterns identified in the VaultChat messages.
The alleged conspiracy period extends from approximately January 2017 through August 2021, a period of approximately four years and eight months. The approximate end of the conspiracy coincides with the initiation of the Cascade Chemical Supply Co. cooperation agreement with the DOJ in September 2021, and with Gavin Holt's resignation from TMC, effective September 30, 2021.
It is important to note for purposes of this analysis that there is no evidence that TMC's senior corporate leadership — including Chief Executive Officer Søren Dalmqvist, General Counsel Priya Anand, Board Chair Margaret Caldwell, or Audit Committee Chair Janet Moreau-Shaw — had knowledge of, authorized, or participated in the alleged conduct. The conduct is attributable primarily to a single individual, Gavin Holt, operating within his functional area of responsibility. This fact is relevant to the cooperation and remediation credit analysis set forth in Section 6 of this report.
2.3 Products at Issue
The three product categories that are the subject of the alleged conspiracy are described below:
High-Purity Feldspar. High-purity feldspar is a naturally occurring mineral used extensively in the production of glass, ceramics, and various industrial applications. It serves as a flux, reducing the melting temperature of raw materials and improving the durability and strength of finished products. TMC is among the largest North American producers of high-purity feldspar, with mining operations in several U.S. and Canadian locations. The high-purity feldspar market in North America is relatively concentrated, with TMC, Ridgecrest, and Pinnacle collectively accounting for a significant share of domestic supply to industrial and chemical-manufacturing customers.
Industrial Talc. Industrial talc is a hydrated magnesium silicate mineral used in a wide range of applications, including plastics (as a reinforcing filler and processing aid), paints and coatings (as a functional extender), ceramics, and certain pharmaceutical applications. Industrial talc is a commodity product with differentiated grades, and pricing is influenced by grade, purity, particle-size distribution, and geographic proximity of production facilities to end users. TMC, Ridgecrest, and Pinnacle are among the leading suppliers of industrial talc to U.S. industrial customers.
Rare-Earth Concentrates. Rare-earth concentrates comprise a group of minerals containing rare-earth elements that are critical inputs for electronics, permanent magnets, clean-energy technologies (including wind turbines and electric vehicle motors), and defense applications. The rare-earth concentrates market has attracted significant attention due to supply-chain concentration and national-security considerations. TMC, Ridgecrest, and Pinnacle each produce or process rare-earth concentrates for sale to U.S. customers, though the market is also subject to significant international competition, particularly from Chinese producers.
All three product categories are sold to U.S. industrial and chemical-manufacturing customers through a combination of long-term supply contracts, annual pricing agreements, spot transactions, and competitive bidding processes. The diversity of sales channels is relevant to the pricing correlation analysis set forth in Section 4 of this report.
Section 3: Methodology — Affected-Commerce Calculation
3.1 DOJ Framework for Affected Commerce
The DOJ Antitrust Division calculates monetary penalties in criminal antitrust cases using a framework rooted in the United States Sentencing Guidelines Manual ("U.S.S.G." or "Sentencing Guidelines"), specifically §2R1.1, which governs bid-rigging, price-fixing, and market-allocation offenses. Under this framework, the starting point for fine calculations is the volume of "affected commerce," which is defined as the total revenue generated by the sale of the products subject to the conspiracy, in the affected market, by all participants in the conspiracy, during the conspiracy period.
The rationale for using affected commerce as the basis for penalty calculations is grounded in the principle that the gravity of an antitrust offense is proportionate to the scale of commerce that was distorted by the anticompetitive conduct. A conspiracy affecting a larger volume of commerce is, ceteris paribus, more harmful to competition and consumers than one affecting a smaller volume, and the penalty should reflect this proportionality.
Under U.S.S.G. §2R1.1(d)(1), the base fine for an antitrust offense is ordinarily set at 20% of the volume of affected commerce. This 20% figure serves as a proxy for the estimated overcharge or anticompetitive gain attributable to the conspiracy. While the actual overcharge in any given case may be higher or lower than 20%, the Sentencing Guidelines employ this standardized percentage as a workable and predictable benchmark for penalty calculations.
DOJ policy guidance further clarifies that the affected-commerce calculation should encompass the aggregate sales of the relevant products in the affected market by all co-conspirators during the conspiracy period. For purposes of calculating a specific defendant's fine, however, the Sentencing Guidelines contemplate that the base fine may be calculated using that defendant's own share of affected commerce or the total affected commerce, depending on the circumstances. In practice, the DOJ typically calculates the base fine for each defendant using that defendant's own affected commerce — that is, the defendant's own sales of the relevant products during the conspiracy period.
This report calculates both the total affected commerce across all participants and TMC's individual share of that total, providing the DOJ with a comprehensive picture of the scope of the alleged conspiracy while focusing the penalty calculation on TMC's own sales volume.
3.2 Data Sources and Collection
The affected-commerce calculation in this report is based on the following data sources for each of the three identified participants:
TMC Data. Sales revenue data for high-purity feldspar, industrial talc, and rare-earth concentrates was extracted from the ERP systems of TMC's U.S. Specialty Minerals Division. The ERP data was supplemented and cross-referenced with invoice-level data from the Division's billing and accounts-receivable systems, as well as customer contract files maintained by the Division's commercial team. Data collection, extraction, and processing were performed by Redstone Digital Forensics Inc. ("Redstone"), under the direction of Calderwood & Harkness. Neil Ashworth, Project Director at Redstone, oversaw the data extraction and processing and provided a data-integrity certification to Hargrove on September 8, 2023. Hargrove performed independent validation procedures on the TMC data, including reconciliation of product-level revenue totals against audited financial statements for FY 2017 through FY 2021.
Ridgecrest Data. Because Hargrove did not have direct access to Ridgecrest's internal financial records, Ridgecrest's sales revenue for the three product categories was estimated using publicly available information. Ridgecrest's total annual revenue was obtained from its SEC filings (10-K annual reports and 10-Q quarterly reports). Ridgecrest reported FY 2021 total revenue of approximately USD 1.92 billion. Product-level revenue breakdowns were estimated using publicly reported segment information, supplemented by NASMC industry benchmark data and third-party market-share analyses. Hargrove notes that these estimates are subject to inherent uncertainty, and the resulting affected-commerce figures for Ridgecrest should be understood as reasonable approximations rather than precise calculations.
Pinnacle Data. Similarly, Pinnacle's sales revenue for the three product categories was estimated from publicly available financial disclosures filed with the Canadian securities regulators via the SEDAR+ system. Pinnacle reported FY 2021 total revenue of approximately CAD 1.45 billion (approximately USD 1.15 billion at prevailing exchange rates). Product-level revenue breakdowns for Pinnacle's U.S. operations were estimated using SEDAR+ filings, NASMC industry benchmarks, and third-party market-share data. As with Ridgecrest, these estimates are identified as approximations.
3.3 Product-by-Product Revenue Analysis
3.3.1 High-Purity Feldspar
TMC U.S. Sales — High-Purity Feldspar (January 2017 – August 2021):
TMC's high-purity feldspar sales grew steadily from FY 2017 through FY 2019, reflecting a combination of increased demand from glass and ceramics manufacturers and the price increases that are the subject of the pricing analysis in Section 4. The modest decline in FY 2020 is attributable in part to demand disruptions caused by the COVID-19 pandemic. The FY 2021 figure reflects only the first eight months of the fiscal year (January through August 2021), consistent with the conspiracy-period end date.
Ridgecrest Estimated U.S. Sales — High-Purity Feldspar (January 2017 – August 2021):
Based on publicly available segment disclosures and industry market-share data, Hargrove estimates that Ridgecrest's U.S. sales of high-purity feldspar during the conspiracy period totaled approximately USD 168.5 million. Ridgecrest's market share in this product category is estimated to have been slightly smaller than TMC's during the relevant period, reflecting Ridgecrest's relative production capacity and geographic footprint.
Pinnacle Estimated U.S. Sales — High-Purity Feldspar (January 2017 – August 2021):
Hargrove estimates that Pinnacle's U.S. sales of high-purity feldspar during the conspiracy period totaled approximately USD 87.3 million. Pinnacle's market position in feldspar is smaller than those of TMC and Ridgecrest, reflecting Pinnacle's primary focus on rare-earth concentrates and its more limited feldspar production capacity.
Sub-Total Affected Commerce — High-Purity Feldspar:
3.3.2 Industrial Talc
TMC U.S. Sales — Industrial Talc (January 2017 – August 2021):
TMC's industrial talc revenue followed a trajectory broadly similar to its feldspar sales, with growth in FY 2017 through FY 2019 and a pandemic-related decline in FY 2020. Industrial talc sales recovered modestly in early FY 2021, driven by demand from plastics and coatings manufacturers.
Ridgecrest Estimated U.S. Sales — Industrial Talc (January 2017 – August 2021):
Ridgecrest is one of the largest domestic producers of industrial talc. Hargrove estimates that Ridgecrest's U.S. sales of industrial talc during the conspiracy period totaled approximately USD 214.8 million. Ridgecrest's market-leading position in talc is reflected in its higher sales volume relative to TMC and Pinnacle in this product category.
Pinnacle Estimated U.S. Sales — Industrial Talc (January 2017 – August 2021):
Hargrove estimates that Pinnacle's U.S. sales of industrial talc during the conspiracy period totaled approximately USD 73.0 million. Pinnacle's talc operations are smaller in scale than its feldspar and rare-earth operations, and its U.S. market share in this category is correspondingly more modest.
Sub-Total Affected Commerce — Industrial Talc:
3.3.3 Rare-Earth Concentrates
TMC U.S. Sales — Rare-Earth Concentrates (January 2017 – August 2021):
TMC's rare-earth concentrates revenue exhibited consistent growth throughout the conspiracy period, driven by increasing demand from clean-energy and defense-sector customers. Unlike feldspar and talc, rare-earth concentrate sales were relatively resilient during the COVID-19 pandemic (FY 2020), reflecting the essential nature of these inputs in strategic supply chains. The FY 2021 figure (January through August) is disproportionately high relative to prior years, reflecting a significant price increase in rare-earth commodities during the first half of 2021.
Ridgecrest Estimated U.S. Sales — Rare-Earth Concentrates (January 2017 – August 2021):
Hargrove estimates that Ridgecrest's U.S. sales of rare-earth concentrates during the conspiracy period totaled approximately USD 140.7 million. Ridgecrest's rare-earth operations are concentrated in its western U.S. mining facilities, and the company has invested significantly in rare-earth processing capacity in recent years.
Pinnacle Estimated U.S. Sales — Rare-Earth Concentrates (January 2017 – August 2021):
Hargrove estimates that Pinnacle's U.S. sales of rare-earth concentrates during the conspiracy period totaled approximately USD 177.3 million. Pinnacle's relatively large share of the rare-earth concentrates category reflects its position as a major North American rare-earth producer, with significant U.S. customer relationships and long-term supply contracts.
Sub-Total Affected Commerce — Rare-Earth Concentrates:
3.4 Aggregate Affected-Commerce Summary
3.4.1 Total Affected Commerce — All Participants
Based on the product-by-product analysis set forth above, the total affected commerce across all three product categories, for all three identified participants, during the conspiracy period of January 2017 through August 2021, is as follows:
Total affected commerce for all participants, all product categories, January 2017 – August 2021: USD 1.34 billion (rounded).
This figure represents the aggregate U.S. sales revenue of the three product categories by all three participants during the conspiracy period. It encompasses both contract sales and spot transactions, and includes all sales to U.S. industrial and chemical-manufacturing customers.
3.4.2 TMC's Share of Affected Commerce
TMC's total affected commerce during the conspiracy period is USD 478 million, representing approximately 35.7% of total affected commerce (USD 478 million / USD 1,339.6 million ≈ 35.67%).
The following table presents TMC's affected commerce by product category and fiscal year:
For context, TMC's U.S. Specialty Minerals Division reported FY 2021 annual revenue of approximately USD 687 million. The affected product categories represent a substantial portion of the Division's revenue in any given year. The conspiracy-period figure of USD 478 million reflects cumulative sales over the approximately four-year-and-eight-month duration of the alleged conspiracy and should not be compared directly to any single-year revenue figure.
3.4.3 Co-Conspirator Shares
Ridgecrest Minerals Inc.
Ridgecrest's estimated total affected commerce during the conspiracy period is approximately USD 524.0 million, representing approximately 39.1% of total affected commerce. Ridgecrest's relative strength in industrial talc — where it holds a market-leading position — accounts for the largest share of its affected commerce.
Pinnacle Earth Resources Ltd.
Pinnacle's estimated total affected commerce during the conspiracy period is approximately USD 337.6 million, representing approximately 25.2% of total affected commerce. Pinnacle's affected commerce is driven primarily by its significant position in rare-earth concentrates, which represents the largest single component of its affected commerce.
The following table summarizes the relative market positions of the three participants during the conspiracy period:
These shares are broadly consistent with the publicly reported market positions of the three companies in the North American specialty-minerals market during the relevant period and provide a reasonable basis for the penalty calculations that follow.
Section 4: Pricing Pattern Analysis
4.1 Methodology
Hargrove conducted an econometric analysis of pricing patterns for all three product categories over the period from FY 2015 through FY 2022. The purpose of this analysis is to assess whether the pricing behavior of TMC, Ridgecrest, and Pinnacle during the alleged conspiracy period (January 2017 – August 2021) is consistent with coordinated pricing, and whether the temporal boundaries of the alleged conspiracy are supported by observable changes in pricing patterns.
The analysis encompasses three distinct periods:
(a) Pre-Conspiracy Period (FY 2015 – FY 2016): This two-year period serves as a competitive baseline, providing a reference point for pricing behavior in the absence of the alleged conspiracy.
(b) Conspiracy Period (January 2017 – August 2021): This is the period during which the alleged price-fixing, customer-allocation, and bid-rigging conduct is alleged to have occurred.
(c) Post-Conspiracy Period (September 2021 – FY 2022): This period follows the approximate end of the conspiracy and provides a basis for assessing whether pricing behavior reverted to competitive norms after the cessation of the alleged conduct.
The analysis employs the following statistical methods:
• Correlation analysis. Hargrove calculated pairwise correlation coefficients for monthly average transaction prices among TMC, Ridgecrest, and Pinnacle for each of the three product categories. Elevated correlation during the conspiracy period, relative to the pre-conspiracy and post-conspiracy baselines, would be consistent with coordinated pricing.
• Price-parallelism testing. Hargrove examined the timing and magnitude of price adjustments by each participant, looking for instances of near-simultaneous or closely sequenced price movements that deviate from patterns attributable to common cost drivers or market conditions.
• Structural break analysis. Hargrove applied Chow tests and Bai-Perron multiple structural-break tests to identify statistically significant changes in the pricing-correlation relationship at or near the beginning and end of the alleged conspiracy period. The presence of structural breaks at these temporal boundaries would provide econometric support for the DOJ's defined conspiracy period.
• Benchmark control variables. NASMC published pricing benchmarks for each of the three product categories were used as control variables to distinguish price movements driven by common market-wide factors (e.g., input-cost changes, demand shocks) from price movements attributable to coordinated conduct.
4.2 Pre-Conspiracy Period (2015–2016) — Baseline
During the pre-conspiracy period, pricing behavior among TMC, Ridgecrest, and Pinnacle exhibited characteristics consistent with competitive oligopolistic dynamics. Specifically:
• Pairwise price-correlation coefficients for the three product categories ranged from 0.42 to 0.61, indicating a moderate degree of price co-movement. This level of correlation is typical in concentrated commodity markets where producers face similar input costs, demand conditions, and macroeconomic influences.
• Price adjustments by individual competitors were observed to lag one another by an average of four to six weeks, suggesting that pricing decisions were made independently, with competitive responses following after a period of market observation. This time-lag pattern is characteristic of firms that are monitoring competitors' pricing behavior and adjusting reactively — a hallmark of competitive, rather than coordinated, behavior.
• There were no instances during the pre-conspiracy period in which all three producers implemented price changes of similar magnitude within a one-week window. The absence of simultaneous or near-simultaneous adjustments is inconsistent with direct coordination and supports the characterization of the pre-conspiracy period as a competitive baseline.
• Price movements during this period tracked closely with the NASMC benchmark indices, indicating that pricing was driven primarily by market fundamentals, including input costs and demand conditions.
4.3 Conspiracy Period (January 2017 – August 2021)
The econometric analysis reveals a statistically significant change in pricing dynamics beginning in early 2017, coinciding with the commencement of the alleged conspiracy. The key findings are as follows:
Elevated Price Correlation. Pairwise price-correlation coefficients for all three product categories increased substantially during the conspiracy period, ranging from 0.83 to 0.96 across the three product categories. This represents a statistically significant increase over the pre-conspiracy baseline (p < 0.01 for all pairwise comparisons using Fisher's z-transformation). The high degree of correlation is consistent with pricing decisions that were informed by direct communication and agreement among the participants, rather than independent decision-making in response to common market forces.
Near-Simultaneous Price Adjustments. Hargrove identified multiple instances during the conspiracy period in which TMC, Ridgecrest, and Pinnacle implemented price adjustments of similar magnitude within a narrow time window (typically zero to five business days). Specifically, Hargrove identified at least fourteen instances of near-simultaneous price adjustments across the three product categories during the conspiracy period, compared with zero such instances during the pre-conspiracy baseline. These near-simultaneous adjustments are inconsistent with the four-to-six-week lag pattern observed during the pre-conspiracy period and are consistent with the existence of a pricing agreement or information exchange.
Correlation with VaultChat Exchanges. The timing of several near-simultaneous price adjustments correlates closely with the at least 37 documented VaultChat encrypted messaging exchanges between Holt and his counterparts at Ridgecrest (Edgerton) and Pinnacle (Tsang), as identified by Calderwood & Harkness's internal investigation. These exchanges spanned the period from March 2017 through July 2021, with the first documented VaultChat exchange between Holt and Edgerton occurring on March 14, 2017. In several instances, VaultChat messages containing pricing information or references to upcoming pricing actions were followed within one to three business days by the implementation of corresponding price changes at TMC and the relevant co-conspirator.
Internal Instructions Correlated with Competitor Movements. The Calderwood & Harkness internal investigation further identified that Sandra Chu, a TMC Pricing Analyst within the U.S. Specialty Minerals Division, received instructions from Holt to adjust published price lists on at least twelve occasions during the conspiracy period. On each of these occasions, the timing and magnitude of the TMC price adjustment correlated with price movements by Ridgecrest or Pinnacle within the same narrow time window, further supporting the inference of coordination.
NASMC Conference Proximity. Hargrove analyzed the relationship between NASMC quarterly conference dates and subsequent price adjustments by the three participants. The analysis revealed that price movements implemented within two to four weeks following NASMC conference dates — at which Holt, Edgerton, and Tsang were known to have attended simultaneously on at least fourteen occasions — showed statistically significant coordination patterns. Specifically, the probability of near-simultaneous price adjustments within the four-week window following NASMC conference dates was approximately 3.7 times higher than the probability of such adjustments during other periods. This finding is consistent with the allegation that in-person meetings at NASMC conferences served as a venue for coordinating pricing decisions.
Deviation from Benchmark Indices. During the conspiracy period, the prices charged by TMC, Ridgecrest, and Pinnacle for all three product categories consistently exceeded the NASMC benchmark indices by a margin that widened over time, ranging from approximately 7% to 14% above benchmark levels. During the pre-conspiracy period, actual transaction prices had tracked the NASMC benchmarks more closely, with deviations generally in the range of 2% to 5%. This widening of the spread between actual prices and benchmark levels is consistent with a coordinated overcharge attributable to the alleged conspiracy.
4.4 Post-Conspiracy Period (September 2021 – 2022)
The pricing analysis reveals a structural break in the correlation patterns following the approximate end of the conspiracy in August 2021, coinciding with the initiation of the Cascade Chemical Supply Co. cooperation agreement with the DOJ and Gavin Holt's departure from TMC (effective September 30, 2021).
Structural Break. The Chow test and Bai-Perron structural-break tests identify statistically significant structural breaks in the pricing-correlation relationship at or near September 2021 for all three product categories (p < 0.01 for feldspar and talc; p < 0.05 for rare-earth concentrates). These structural breaks indicate that the statistical relationship governing pricing dynamics changed materially at the temporal boundary identified by the DOJ as the approximate end of the conspiracy.
Return to Competitive Patterns. Following the structural break, pairwise price-correlation coefficients declined to levels broadly consistent with the pre-conspiracy baseline, ranging from 0.38 to 0.57 across the three product categories. The time-lag pattern between competitors' price adjustments also reverted to the four-to-six-week range observed during the pre-conspiracy period, suggesting a return to independent, competitive pricing behavior.
Divergence in Pricing Strategies. In the post-conspiracy period, TMC, Ridgecrest, and Pinnacle exhibited increasingly divergent pricing strategies, with each company pursuing independent pricing paths that reflected its own cost structure, capacity utilization, and competitive positioning. This divergence stands in contrast to the tight alignment observed during the conspiracy period and supports the conclusion that the departure of Holt — the central TMC figure in the alleged conspiracy — was accompanied by a cessation of coordinated pricing behavior.
4.5 Summary of Pricing Analysis Findings
The economic evidence set forth in this section is consistent with the existence of a pricing agreement among TMC, Ridgecrest, and Pinnacle during the alleged conspiracy period of January 2017 through August 2021. Specifically:
1. Price-correlation coefficients during the conspiracy period were statistically significantly higher than during both the pre-conspiracy and post-conspiracy periods.
2. Near-simultaneous price adjustments occurred at a frequency and with a consistency that is not explained by common market forces and is correlated with documented VaultChat exchanges and NASMC conference attendance.
3. Structural-break analysis confirms that the statistical relationship governing pricing dynamics changed materially at the temporal boundaries of the alleged conspiracy.
4. The return to competitive pricing patterns in the post-conspiracy period is consistent with the cessation of coordinated conduct following Holt's departure and the initiation of the DOJ investigation.
These findings support the temporal scope defined by the DOJ (January 2017 through August 2021) and provide econometric corroboration for the existence of the alleged pricing agreement. Detailed statistical results, including correlation coefficients, test statistics, and confidence intervals, are presented in Exhibit C.
Section 5: Penalty Calculation Framework
5.1 DOJ Antitrust Division Fine Calculation Methodology
The DOJ Antitrust Division calculates monetary penalties in criminal antitrust cases using a structured methodology derived from the United States Sentencing Guidelines and internal DOJ policy. The principal elements of this methodology are as follows:
Base Fine (U.S.S.G. §2R1.1). The base fine for an antitrust offense is ordinarily calculated as 20% of the volume of affected commerce attributable to the defendant during the conspiracy period. This 20% figure is established by U.S.S.G. §2R1.1(d)(1) and serves as the standard starting point for penalty negotiations in criminal antitrust matters. The 20% figure represents a proxy for the typical competitive harm or overcharge associated with price-fixing conspiracies, although the actual overcharge in any individual case may differ. The DOJ consistently applies this 20% standard in its criminal antitrust enforcement practice.
Culpability Score Adjustments. The Sentencing Guidelines provide for adjustments to the base fine based on a culpability score that reflects both aggravating and mitigating factors. Aggravating factors that may increase the penalty include involvement of high-level personnel, prior criminal history of the organization, obstruction of justice, and tolerance of the offense by management. Mitigating factors that may reduce the penalty include timely self-reporting of the offense, full cooperation with the investigation, acceptance of responsibility, implementation of an effective compliance and ethics program, and remediation of the offense.
Cooperation Credit. The DOJ Antitrust Division has articulated policies regarding cooperation credit in criminal antitrust matters. These policies, set forth in various Deputy Assistant Attorney General speeches and policy memoranda, establish a framework under which defendants that provide timely, complete, and valuable cooperation to the DOJ may receive meaningful reductions from the base fine. The magnitude of the cooperation credit depends on a range of factors, including the timeliness of the cooperation, the volume and quality of document production, the availability of witnesses, the disclosure of internal investigation findings, and the implementation of compliance remediation.
Recent Precedents. In recent years, the DOJ Antitrust Division has resolved a number of criminal antitrust matters through NPAs and plea agreements in which the final monetary penalties reflect cooperation credits ranging from approximately 25% to 60% of the base fine, depending on the nature and extent of the defendant's cooperation and remediation efforts. A survey of comparable precedents is presented in Exhibit E and is discussed further in Section 6.6 of this report.
5.2 Base Fine Calculation — TMC
Applying the standard 20% methodology to TMC's affected commerce of USD 478 million, the base fine is calculated as follows:
Base Fine = TMC Affected Commerce × 20%
Base Fine = USD 478,000,000 × 0.20 = USD 95,600,000
The base fine of USD 95.6 million constitutes the starting point for penalty negotiations between TMC (through Calderwood & Harkness) and the DOJ Antitrust Division. This figure is subject to adjustment based on the cooperation and remediation credit analysis set forth in Section 6, as well as any additional considerations raised by the DOJ during the course of negotiations.
5.3 Statutory Maximum
For completeness, the statutory maximum penalties applicable to TMC's alleged conduct are set forth below:
Sherman Act, 15 U.S.C. §1. The Sherman Act provides for a maximum corporate fine of USD 100 million for violations of Section 1. However, this statutory maximum is subject to the alternative-fine provision of 18 U.S.C. §3571(d), which permits a fine of up to twice the gross gain derived from the offense or twice the gross loss caused to the victims of the offense, whichever is greater.
18 U.S.C. §3571(d) — Alternative Fine. Under the alternative-fine provision, the maximum fine could theoretically exceed the USD 100 million statutory cap if the DOJ can demonstrate that the gain or loss attributable to the conspiracy exceeds USD 50 million. Given the total affected commerce of USD 1.34 billion and the estimated overcharge range, it is plausible that the alternative-fine calculation could yield a figure substantially in excess of USD 100 million. However, in practice, the DOJ's standard approach to penalty calculation in NPA and plea agreement negotiations is grounded in the 20% of affected commerce methodology, and the alternative-fine provision is typically invoked only in cases where the 20% calculation yields a figure below the statutory minimum or where the DOJ seeks to impose a particularly severe penalty. In this matter, the 20% calculation yields a base fine of USD 95.6 million, which is within the USD 100 million statutory cap and is consistent with the DOJ's standard approach.
For purposes of this report, the penalty analysis proceeds from the USD 95.6 million base fine rather than from the alternative-fine maximum, as the 20% methodology is the working framework for the NPA negotiations.
Section 6: Cooperation and Remediation Credit Analysis
6.1 DOJ Cooperation Credit Framework
The DOJ Antitrust Division's policies on cooperation credit provide that defendants who cooperate with the government's investigation may receive meaningful reductions in monetary penalties. The policies recognize that cooperation by targets and subjects of antitrust investigations serves important law-enforcement objectives, including the identification of additional participants, the preservation and production of evidence, and the efficient resolution of complex investigations.
The DOJ evaluates cooperation credit based on the following factors, among others:
(a) Timeliness of cooperation. Whether the defendant commenced cooperation promptly after becoming aware of the investigation, and whether the cooperation was proactive rather than reactive.
(b) Completeness and quality of document production. Whether the defendant produced documents and data in a timely, complete, and organized manner, and whether the production was responsive to the government's requests.
(c) Availability of witnesses. Whether the defendant made current and former employees available for interviews and testimony, and whether the witnesses were cooperative and truthful.
(d) Disclosure of internal investigation findings. Whether the defendant conducted a thorough internal investigation and disclosed the findings to the DOJ, including information that was inculpatory or adverse to the defendant's interests.
(e) Compliance remediation. Whether the defendant implemented or committed to implementing meaningful reforms to its compliance program to prevent future violations.
(f) Nature and extent of the offense. Whether the defendant's conduct was attributable to a small number of individuals or reflected a broader organizational culture of non-compliance, and whether the defendant's senior leadership was involved in or aware of the conduct.
6.2 TMC's Cooperation Record
TMC's cooperation with the DOJ investigation has been substantial and timely. The key elements of TMC's cooperation record are summarized below:
Prompt Retention of Counsel. TMC engaged Calderwood & Harkness LLP on February 18, 2022, just four days after receiving the first grand jury subpoena (Subpoena No. GJ-22-0194-SD-003, dated February 14, 2022). The prompt engagement of experienced antitrust defense counsel reflects TMC's commitment to understanding and responding to the investigation in a responsible and timely manner.
Litigation Hold. A comprehensive litigation hold was issued by TMC's General Counsel, Priya Anand, on March 1, 2022, approximately two weeks after the subpoena was received. The litigation hold encompassed all potentially relevant documents and data, including electronic communications, pricing records, customer files, and trade-association materials, and was communicated to all employees in the U.S. Specialty Minerals Division and relevant corporate functions.
Document Production. TMC initiated its first rolling production of documents on April 4, 2022, approximately seven weeks after receiving the subpoena. This initial production comprised approximately 42,000 documents. Subsequent rolling productions continued on a regular cadence throughout 2022 and 2023, resulting in a cumulative production of approximately 487,000 documents by December 15, 2022 (in response to the first subpoena), plus approximately 68,000 additional documents by June 30, 2023 (in response to the second subpoena). In total, TMC has produced approximately 555,000 documents encompassing approximately 3.2 million pages. The document production was managed by Redstone Digital Forensics Inc. under the direction of Calderwood & Harkness and was organized and indexed in accordance with the DOJ's production specifications.
