INTERNAL MEMORANDUM

July 20, 2025

I. Executive Summary

This memorandum assesses whether Pinnacle Market Group Inc. ("Pinnacle" or "PMG") qualifies for the traditional failing-firm defense under Section 7 of the Clayton Act, 15 U.S.C. § 18, and, alternatively, whether Pinnacle's deteriorating competitive position supports a "weakened competitor" or "flailing firm" argument that materially diminishes the anticompetitive potential of Cascade Retail Holdings Inc.'s ("Cascade" or "CRH") proposed $4.7 billion acquisition of Pinnacle. The analysis is conducted in the context of the Federal Trade Commission's ("FTC" or "Commission") challenge to the merger, presently pending before the Honorable Richard A. Johannsen in the Western District of Washington and before the Commission on an administrative complaint.

Bottom-Line Conclusion. Pinnacle does not satisfy the strict three-pronged failing-firm defense. Specifically, Pinnacle is not facing imminent business failure: it generated $11.4 billion in gross merchandise volume ("GMV") and $1.82 billion in net revenue in FY2024, maintains approximately 185,000 active sellers, and carried a pre-announcement market capitalization of approximately $3.9 billion. The company has not exhausted reorganization alternatives, has not engaged restructuring advisors, and has not filed for bankruptcy. Moreover, the sale process conducted by Ridgeline Capital Partners generated interest from multiple potential acquirers, and the record does not clearly establish that no alternative, less-anticompetitive purchaser existed. Accordingly, none of the three traditional prongs of the failing-firm defense can be established to the satisfaction of a court.

However, Pinnacle's competitive trajectory — marked by dramatically decelerating GMV growth (from 28% year-over-year ("YoY") in FY2022 to 9% YoY in FY2024) and sharply rising seller churn (from 12% in FY2022 to 21% in FY2024) — supports a powerful alternative argument that the merger's anticompetitive potential is materially reduced because Pinnacle's future competitive significance is substantially diminished. Under the analytical framework established by the Supreme Court in United States v. Fenmore Industries, 415 U.S. 486 (1974), and applied by the D.C. district court in FTC v. Arch Coal, Inc., 329 F. Supp. 2d 109 (D.D.C. 2004), Pinnacle's historical 30.1% market share (under the FTC's proposed relevant market) significantly overstates the company's future ability to compete. This evidence directly undermines the FTC's prima facie case and reduces both the likely magnitude of any anticompetitive effect and the forward-looking concentration metrics on which the Commission relies.

Recommendation. We should pursue the weakened/flailing firm argument as a secondary defense pillar alongside the primary market definition and efficiencies defenses in the Memorandum in Opposition to the FTC's Motion for Preliminary Injunction (due August 11, 2025). The strict failing-firm defense should be reserved in our pleadings for completeness — it has already been asserted as an affirmative defense in Cascade's answer — but it should not be featured prominently at the September 8, 2025 preliminary injunction hearing before Judge Johannsen. Leading with an aggressive failing-firm defense that cannot be sustained risks undermining Cascade's broader credibility and may be perceived as inconsistent with the procompetitive narrative that frames our primary defense theories.

This memorandum should be read in conjunction with the Efficiencies Defense Memorandum (dated July 18, 2025, from A. Liu to E. Nguyen), the Market Definition Analysis Memorandum (dated July 10, 2025, from E. Nguyen to Howard Bellamy), and the Memorandum on the Preliminary Injunction Standard Under Section 13(b) (dated July 5, 2025, from E. Nguyen to H. Bellamy).

II. Background

A. Transaction Overview

On March 14, 2025, Cascade Retail Holdings Inc. and Pinnacle Market Group Inc. executed an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which CRH Merger Sub Inc., a wholly owned subsidiary of Cascade formed for the purpose of the transaction, will merge with and into Pinnacle, with Pinnacle surviving as a wholly owned subsidiary of Cascade. The transaction is structured as an all-cash reverse triangular merger. The transaction was publicly announced on March 17, 2025, when Cascade and Pinnacle each filed a Form 8-K with the Securities and Exchange Commission disclosing the material terms of the Merger Agreement.

The aggregate consideration payable to Pinnacle shareholders is approximately $4.7 billion, calculated as $26.85 per share multiplied by 175,047,319 shares of Pinnacle common stock outstanding. This per-share price represents a premium of approximately 20.4% over Pinnacle's unaffected closing price of $22.30 on March 7, 2025 — the last trading day before market speculation regarding a potential transaction began to affect Pinnacle's stock price.

Cascade is financing the transaction through a combination of $1.9 billion in cash on hand and $2.8 billion in borrowings under a senior secured Term Loan B facility committed by Whitmore National Bank, N.A. pursuant to a commitment letter dated March 12, 2025. In addition, Cascade has secured a $500 million revolving credit facility, which is expected to remain undrawn at closing and is available for post-closing working capital purposes and integration expenditures.

Pinnacle retained Ridgeline Capital Partners, a San Francisco-based investment bank, as its financial advisor for the transaction. Nadine Vasquez, Managing Director at Ridgeline, led the engagement. Cascade retained Mercer Hollis & Co. of New York as its financial advisor. Transaction counsel for Cascade is Harmon Ridgeway & Strauss LLP, with Phillip Strauss serving as lead M&A partner.

The parties filed their pre-merger notification under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, 15 U.S.C. § 18a, on April 2, 2025 (Transaction No. HSR-20250402-0347). The FTC issued a Second Request for additional information and documentary material on May 7, 2025 (File No. 251-0089). Cascade certified substantial compliance with the Second Request on June 10, 2025.

The Merger Agreement provides for an outside date of March 14, 2026, subject to extension to June 14, 2026 if the sole unsatisfied closing condition as of March 14, 2026 is the receipt of antitrust clearance. The agreement further provides for a reverse termination fee of $282 million (approximately 6% of deal value), payable by Cascade to Pinnacle in the event the transaction fails to close due to the failure to obtain required antitrust approvals. Pinnacle is obligated to pay a company termination fee of $164.5 million (approximately 3.5% of deal value) if it terminates the Merger Agreement to accept a superior proposal or under certain other circumstances specified in the agreement.

B. FTC Challenge

On June 20, 2025, the FTC issued an administrative complaint (Docket No. 9438) challenging the proposed acquisition under Section 7 of the Clayton Act, 15 U.S.C. § 18. Three days later, on June 23, 2025, the Commission filed a complaint in the United States District Court for the Western District of Washington, Seattle Division, seeking a temporary restraining order and preliminary injunction pursuant to Section 13(b) of the FTC Act, 15 U.S.C. § 53(b), to prevent consummation of the merger pending resolution of the administrative proceeding. The district court action was assigned Case No. 2:25-cv-01087-RAJ and is before the Honorable Richard A. Johannsen.

The Commission authorized the filing of the complaint by a 3–2 vote, reflecting significant internal disagreement regarding the merits of the challenge. The identity and reasoning of the dissenting commissioners may be relevant to our defense strategy, and their dissenting statements — to the extent they have been made public — should be reviewed for language that may support the weakened-competitor argument or otherwise undercut the majority's theory of competitive harm.

The FTC's litigation team is led by Claire Dunmore, Lead Trial Attorney in the Bureau of Competition's Mergers IV Division. She is supported by Samuel Ortega, Senior Trial Counsel, and Rebecca Yun, Staff Attorney. Dr. Nathaniel Hargrove of the Bureau of Economics serves as the staff economist for the matter.

The FTC alleges that the relevant product market is "online marketplace platform services for third-party sellers in the United States." Within this market, the Commission alleges the following market shares based on GMV:

Based on these market shares, the FTC calculates a pre-merger Herfindahl-Hirschman Index ("HHI") of 2,361, a post-merger HHI of 2,856, and a delta (increase) of 495. These figures place the transaction well above the presumption thresholds established in the 2023 Merger Guidelines, which treat mergers resulting in a post-merger HHI above 2,500 with a delta above 200 as presumptively anticompetitive.

Judge Johannsen has scheduled the evidentiary hearing on the FTC's motion for preliminary injunction to begin September 8, 2025, with an estimated duration of five court days. Cascade's opposition to the preliminary injunction motion is due August 11, 2025.

C. Pinnacle Market Group — Company Profile

Pinnacle Market Group Inc. is a Delaware corporation headquartered at 500 East 6th Street, Suite 800, Austin, Texas 78701. The company was founded in 2014 by Rajiv Chandravar (Co-Founder and Chief Executive Officer) and Lena Kowalski (Co-Founder and Chief Product Officer). Thomas Breck serves as Chief Financial Officer, and Anita Suresh serves as General Counsel. Pinnacle completed its initial public offering on the Nasdaq Stock Market on September 18, 2020, under the ticker symbol PMGI.

Pinnacle operates an online marketplace platform that connects independent sellers with consumers across a range of product categories, including home goods, artisanal products, specialty foods, fashion, and consumer electronics. The platform serves as an intermediary, providing sellers with storefronts, payment processing, search and discovery tools, and logistics integration while offering consumers a curated marketplace experience. Pinnacle generates revenue primarily through commissions on transactions completed on its platform, commonly referred to as a "take rate."

For FY2024 (the fiscal year ending December 31, 2024), Pinnacle reported approximately 185,000 active sellers, $11.4 billion in GMV, and $1.82 billion in net revenue, reflecting a take rate of approximately 16%. The company's pre-announcement market capitalization — calculated based on 175,047,319 shares outstanding and the unaffected closing price of $22.30 as of March 7, 2025 — was approximately $3.9 billion.

Pinnacle's independent auditor is Kessler Fong Accounting Group LLP of Dallas, Texas. In connection with this litigation, Pinnacle is represented by Whitfield, Greer & Tanaka LLP, with Diana Whitfield (Lead Partner) and Kenneth Oshiro (Senior Associate) based in Austin, Texas, leading the defense effort on Pinnacle's behalf.

III. Legal Framework

A. The Traditional Failing-Firm Defense

The failing-firm defense has its origins in the Supreme Court's decision in International Shoe Co. v. FTC, 280 U.S. 291 (1930), in which the Court recognized that a merger with a failing company is not properly condemned under the antitrust laws because the competitive conditions in the market would deteriorate regardless of whether the merger proceeds. The rationale underlying the defense is fundamentally one of causation: if the acquired firm would exit the market irrespective of the merger, then the merger does not cause the diminution of competition that Section 7 of the Clayton Act is designed to prevent.

The modern articulation of the failing-firm defense was established by the Supreme Court in Citizen Publishing Co. v. United States, 394 U.S. 131 (1969). Under Citizen Publishing, the defense requires the merging parties to establish three elements:

1. Imminent Business Failure. The acquired firm faces the grave probability of a business failure. Its resources must be so depleted and its prospects for rehabilitation so remote that the firm is on the verge of financial collapse. It is not sufficient that the firm is merely experiencing competitive difficulties, declining profitability, or adverse market trends; the standard requires a showing of imminent insolvency or the functional equivalent thereof.

2. No Reasonable Prospect of Successful Reorganization. The firm has no reasonable prospect of successfully reorganizing its affairs, including through proceedings under Chapter 11 of the Bankruptcy Code. This prong requires the firm to demonstrate that reorganization — whether through bankruptcy, operational restructuring, asset sales, or other alternatives — would not preserve the firm as a viable competitive entity.

3. No Alternative Less-Anticompetitive Purchaser. The firm has made good-faith but unsuccessful efforts to elicit reasonable alternative offers from other potential purchasers that would pose a less severe threat to competition than the proposed acquirer. This prong ensures that the acquired firm has exhausted less anticompetitive transactional alternatives before resorting to a merger that raises significant competitive concerns.

The Department of Justice and the Federal Trade Commission have recognized the failing-firm defense in successive iterations of the Horizontal Merger Guidelines. The current Guidelines acknowledge the defense but describe it as "rarely" applicable, emphasizing that all three prongs must be satisfied and that the burden of proof falls squarely on the merging parties. The Guidelines further note that a company is not considered to be "failing" merely because it has experienced declining revenues, reduced profitability, or competitive difficulties; rather, the defense contemplates a firm that is genuinely unable to meet its financial obligations in the near term.

The allocation of the burden of proof to the defendants is well-established and has been applied consistently across federal circuits. The applicable standard of proof is somewhat less settled. Several circuits have required clear and convincing evidence, while others apply a preponderance-of-the-evidence standard. For present purposes, we note that this case is venued in the Western District of Washington and that the Ninth Circuit has not definitively resolved the question. However, under either standard, the evidence must be substantial, and courts have uniformly applied the defense with considerable strictness.

Key precedents illustrating the defense's demanding requirements include FTC v. Warner Communications, in which the court emphasized the high evidentiary bar the defense imposes, and California v. Sutter Health System, in which the court applied the defense narrowly and found it unsatisfied despite evidence of the acquired firm's financial difficulties. The consistent theme in the case law is that the failing-firm defense is an exceptional doctrine that applies only in extraordinary circumstances.

B. The "Weakened Competitor" / "Flailing Firm" Alternative

Distinct from the strict failing-firm defense is the "weakened competitor" or "flailing firm" argument — a broader analytical framework that does not require a showing of imminent business failure but instead challenges the inferential value of historical market share data as a predictor of future competitive significance. The weakened-competitor argument operates within the competitive effects analysis rather than as a standalone affirmative defense. Its core contention is that where one of the merging firms is a declining competitive force — losing customers, market share, or competitive capabilities — the merger's likely anticompetitive effects are diminished because the acquired firm's historical market share overstates its future importance to competition.

The Horizontal Merger Guidelines recognize this concept as a relevant factor in assessing competitive effects. The Guidelines observe that a firm's current market position may not reflect its future competitive significance if the firm is experiencing a sustained decline in competitive vitality. In such circumstances, the Guidelines contemplate that the merger's likely effect on competition may be less than what concentration statistics alone would suggest.

The seminal precedent for this analytical approach is the Supreme Court's decision in United States v. Fenmore Industries, 415 U.S. 486 (1974). In Severin Holdings, the Court evaluated a merger between coal producers and held that the acquired firm's historical market share — measured by past production — was a misleading indicator of its future competitive significance because the firm's coal reserves were largely committed under long-term contracts, leaving it with little capacity to compete for new business. The Court articulated the principle that the proper inquiry under Section 7 is not the firm's past competitive position but rather its "future ability to compete." Where evidence demonstrates that a firm's competitive resources are depleted or declining, market share data drawn from historical periods will overstate the merger's competitive impact.

The Severin Holdings framework was applied with particular force in FTC v. Arch Coal, Inc., 329 F. Supp. 2d 109 (D.D.C. 2004). In Arch Coal, the FTC sought a preliminary injunction against a coal industry merger, and the court denied the request in part because the evidence demonstrated that the target firm's competitive position was declining. The court credited the defendants' showing that the target's market share overstated its future competitive significance and concluded that the FTC had not established a likelihood of success on the merits. Critically, the Arch Coal court reached this conclusion without requiring the defendants to satisfy the strict three-pronged failing-firm defense. The weakened-competitor analysis operated independently as a challenge to the FTC's prima facie case.

Additional support for the weakened-competitor framework can be found in FTC v. Tronox Ltd., where the court applied a weakened-competitor analysis in assessing the future competitive significance of the target firm. While the court in Tronox ultimately credited the FTC's challenge, the decision acknowledged the analytical validity of the weakened-competitor framework and engaged with the defendants' evidence on the point.

The weakened-competitor argument does not require the merging parties to satisfy the three prongs of the failing-firm defense. It is not a substitute for or lesser version of the failing-firm defense but rather a distinct analytical tool that challenges the FTC's reliance on historical market share data. Courts considering the weakened-competitor argument have examined a range of indicators, including:

• Declining sales volumes and revenue

• Loss of customers, suppliers, or — in the marketplace context — sellers

• Departure of key personnel, particularly in technology, engineering, and senior leadership roles

• Technological obsolescence or failure to keep pace with competitors' innovations

• Inability to attract new capital investment or rising cost of capital

• Competitive entry by stronger or more innovative rivals

• Erosion of the firm's competitive advantages or differentiating features

The application of the weakened-competitor framework to two-sided marketplace platforms presents a particularly compelling dynamic. In a two-sided marketplace, the platform's value to each side of the market is a function of participation on the other side: sellers are attracted by the presence of a large and active buyer base, and buyers are attracted by a broad and diverse selection of sellers and products. These cross-platform network effects create a virtuous cycle when the platform is growing — more sellers attract more buyers, which in turn attracts more sellers. However, the same dynamic operates in reverse when the platform is contracting. Declining seller participation reduces product selection, which reduces buyer traffic, which further diminishes seller returns and accelerates seller departures. This negative feedback loop — sometimes described as a "death spiral" dynamic — means that the loss of competitive vitality in a marketplace platform can be self-reinforcing and difficult to reverse, amplifying the significance of the weakened-competitor evidence.

It should be noted that the weakened-competitor argument is most effective when deployed in combination with other defense theories. Where the defendants can also challenge the FTC's market definition (demonstrating that the relevant market is broader than the FTC alleges), establish cognizable merger-specific efficiencies, and show ease of competitive entry, the weakened-competitor evidence provides an additional — and often independently sufficient — basis for rebutting the government's prima facie case.

C. Relationship to Section 13(b) Preliminary Injunction Standard

The procedural posture of this matter warrants particular attention to the standard governing the FTC's motion for preliminary injunction. Under Section 13(b) of the FTC Act, 15 U.S.C. § 53(b), the Commission is entitled to a preliminary injunction upon demonstrating (1) a likelihood that it will succeed on the merits of its Section 7 claim in the administrative proceeding, and (2) that the equities tip in favor of injunctive relief. This standard is less demanding than the traditional four-factor preliminary injunction test applied in private litigation; in particular, the FTC is not required to demonstrate irreparable harm as a separate element. Nonetheless, the court retains discretion to weigh the equities, including the public interest in permitting or prohibiting the transaction.

The weakened-competitor evidence is relevant to both prongs of the Section 13(b) analysis. With respect to the likelihood of success, the evidence directly undermines the FTC's ability to prove a Section 7 violation. The Commission's case rests on the premise that the merger of two significant marketplace competitors — yielding a combined market share of 38.3% — will substantially lessen competition. But if Pinnacle's 30.1% share is declining and likely to continue declining, the merger does not eliminate a competitive force of the magnitude the FTC alleges. The forward-looking competitive significance of the acquired firm is materially less than its historical market share suggests, and the FTC's prima facie case is correspondingly weaker.

With respect to the equities, the weakened-competitor evidence demonstrates that blocking the merger may not serve the public interest. If Pinnacle continues to decline independently — losing sellers, losing market share, and potentially entering a negative-feedback-loop dynamic — the ultimate result for consumers and sellers may be worse than permitting the merger to proceed. Consumers face a diminished marketplace experience as Pinnacle's product selection narrows, and sellers face reduced returns as Pinnacle's buyer traffic declines. The merger offers an alternative future in which Cascade's resources and infrastructure are deployed to stabilize and revitalize Pinnacle's marketplace, preserving competitive options for consumers and sellers. This equity consideration should be presented to Judge Johannsen as a complement to the merits arguments.

For a more detailed treatment of the Section 13(b) standard and its application to the facts of this case, we refer to the Memorandum on the Preliminary Injunction Standard Under Section 13(b) (dated July 5, 2025, from Elliot Nguyen to Howard Bellamy).

IV. Analysis of the Traditional Failing-Firm Defense as Applied to Pinnacle

A. Prong 1: Imminent Business Failure

Assessment: NOT MET.

The first prong of the failing-firm defense requires a showing that the acquired firm faces the "grave probability of a business failure" — that its resources are so depleted and its prospects for rehabilitation so remote that it is on the verge of ceasing to operate as a going concern. This prong sets an extraordinarily high bar, and Pinnacle does not clear it.

Pinnacle's FY2024 financial results, while reflecting significant deceleration from prior years, do not remotely suggest imminent business failure. The company generated $11.4 billion in GMV and $1.82 billion in net revenue during FY2024. It maintained approximately 185,000 active sellers on its platform and continued to process millions of consumer transactions. While operating margins have compressed — a trend we discuss in greater detail in Section V.D below — the company remains profitable and is not generating negative cash flow on an overall basis. Pinnacle is not insolvent, is not in default on any material financial obligations, and is not unable to meet its liabilities as they come due.

The company's pre-announcement market capitalization of approximately $3.9 billion further undermines any claim of imminent failure. The public equity markets — while imperfect — reflect the consensus assessment of informed investors regarding a company's financial viability and future prospects. A company valued at nearly $4 billion by the public markets is not, by any reasonable measure, on the brink of business failure.

It is true that Pinnacle's growth has decelerated dramatically, from 28% YoY GMV growth in FY2022 to 9% YoY in FY2024. This deceleration is significant and forms the foundation of our weakened-competitor argument. But deceleration is not decline, and decline is not failure. Pinnacle is still growing — albeit slowly and below the industry average — and growth, even diminished growth, is fundamentally inconsistent with the concept of imminent business failure.

The FTC will undoubtedly argue that a company generating $1.82 billion in annual revenue, supporting 185,000 active sellers, and carrying a $3.9 billion market capitalization cannot credibly claim to be on the verge of failure. This argument has substantial force, and we would be ill-advised to contest it aggressively. Attempting to portray Pinnacle as imminently failing would lack evidentiary support and would invite skepticism from Judge Johannsen at a critical juncture in the proceedings.

Conclusion on Prong 1: Pinnacle is not on the verge of imminent business failure. This prong of the failing-firm defense is not satisfied.

B. Prong 2: Inability to Reorganize Successfully

Assessment: NOT MET.

The second prong requires a showing that the acquired firm has no reasonable prospect of successful reorganization, including through Chapter 11 proceedings. The purpose of this prong is to ensure that the acquired firm has explored all viable alternatives to a potentially anticompetitive merger before invoking the failing-firm defense as a justification for the transaction.

There is no evidence in the record that Pinnacle has explored or is unable to pursue reorganization. The company has not filed for bankruptcy, has not engaged restructuring advisors (so far as our diligence has revealed), and continues to operate its marketplace platform in the ordinary course of business. Pinnacle has not announced layoffs, facility closures, or other operational restructuring measures of the type that would ordinarily precede or accompany a reorganization effort.

Moreover, Pinnacle retains meaningful financial resources that could be deployed to fund a turnaround strategy. The company has cash reserves on its balance sheet, access to its existing credit facilities, and publicly traded equity that could be used to raise additional capital. Pinnacle's stock, while trading at a discount from its post-IPO highs, remains actively traded on the Nasdaq Stock Market and could serve as a basis for secondary offerings or other capital-raising transactions.

We also note that Lena Kowalski, Pinnacle's Co-Founder and Chief Product Officer, has reportedly spearheaded internal product redesign initiatives aimed at stemming seller churn and improving platform competitiveness. While these initiatives have not yet reversed the negative trends — seller churn continued to rise in FY2024 — the existence of internal turnaround efforts undercuts any argument that reorganization is not a reasonable prospect. The FTC would point to these very initiatives as evidence that Pinnacle has viable alternatives to the merger.

Conclusion on Prong 2: This prong is not satisfied. Pinnacle has not exhausted — or even seriously explored — reorganization alternatives, and its financial position permits such exploration.

C. Prong 3: No Alternative Less-Anticompetitive Purchaser

Assessment: LIKELY NOT MET (but the evidence is more nuanced than the first two prongs).

The third prong requires a showing that the acquired firm made good-faith but unsuccessful efforts to elicit reasonable alternative offers from purchasers that would pose a less severe threat to competition. This prong is designed to ensure that the acquired firm has not simply accepted the most lucrative bid without regard to the antitrust implications, and that no less anticompetitive alternative exists.

The facts relating to this prong are more nuanced than those relating to the first two prongs. Under the Merger Agreement, Pinnacle conducted a sale process advised by Ridgeline Capital Partners, with Nadine Vasquez serving as Managing Director on the engagement. Our understanding from transaction counsel at Harmon Ridgeway & Strauss LLP is that the sale process generated indications of interest from several potential acquirers. Cascade's all-cash offer at $26.85 per share — representing a 20.4% premium to Pinnacle's unaffected stock price — was ultimately determined by Pinnacle's board of directors to be the highest and most certain bid.

The Merger Agreement includes a company termination fee of $164.5 million (3.5% of deal value) applicable if Pinnacle terminates the agreement to accept a superior proposal. The existence of this "fiduciary out" provision — standard in public company mergers — indicates that the parties contemplated the possibility that an alternative acquirer might emerge and structured the agreement to permit Pinnacle's board to accept a superior offer if one materialized, subject to the payment of the termination fee.

However, to satisfy the third prong of the failing-firm defense, Cascade would need to demonstrate more than that it was the highest bidder. It would need to show that no less anticompetitive alternative purchaser was available — for example, a purchaser that does not operate in the online marketplace space and whose acquisition of Pinnacle would therefore not raise the same horizontal overlap concerns. The record may not support this showing. If the sale process attracted interest from financial buyers (private equity firms) or strategic acquirers outside the marketplace sector, and if those parties declined to bid at levels comparable to Cascade's offer, the analysis becomes more favorable. But if such parties were never seriously solicited, or if they were never given a meaningful opportunity to submit proposals, the prong is unlikely to be met.

One potential argument is that any alternative purchaser with meaningful marketplace or e-commerce operations would present substantially similar antitrust concerns, and that a pure financial buyer was not willing to pay a premium comparable to Cascade's offer. This argument has some surface appeal — financial buyers typically cannot match the synergy-driven valuations offered by strategic acquirers — but it requires further factual development. We would need to review the sale process materials prepared by Ridgeline Capital Partners and interview relevant participants to determine the identity and nature of the parties contacted, the bids (if any) received, and the reasons those bids were rejected or not pursued.

Conclusion on Prong 3: The evidence is mixed and probably insufficient to meet the defendants' burden. While the sale process generated some competitive interest, the record does not clearly establish that no less anticompetitive alternative was available. Further factual development is warranted, but this prong should not be relied upon as a basis for asserting the failing-firm defense at the PI hearing.

D. Overall Conclusion on the Failing-Firm Defense

The traditional failing-firm defense is not viable for Pinnacle under the current facts. Pinnacle is not facing imminent business failure, has not exhausted reorganization alternatives, and the record does not clearly establish the absence of a less anticompetitive alternative purchaser. All three prongs of the defense — as articulated in Citizen Publishing and consistently applied by the courts — remain unsatisfied.

We recommend that the failing-firm defense be preserved in our answer and pleadings. It has already been asserted as an affirmative defense in Cascade's answer to the FTC's complaint, and withdrawing it could be construed as a concession. However, we should not feature it prominently at the PI hearing and should not devote significant space to it in the Memorandum in Opposition to the FTC's motion for preliminary injunction.

There are two significant risks associated with leading with the failing-firm defense at the PI hearing. First, if the court rejects the argument — as it almost certainly would on the current record — the rejection may undermine our credibility on other, more viable defense theories. Judges are sensitive to overreaching, and presenting an argument that the evidence cannot support invites the court to view the rest of our defense with heightened skepticism. Second, the failing-firm defense is in some tension with Cascade's stated procompetitive rationale for the merger. Cascade's narrative — articulated in public filings, press releases, and the testimony we intend to present — is that the acquisition will create a stronger, more innovative marketplace platform that will enhance competition with Vertex Commerce and other rivals. Characterizing Pinnacle as a "failing" firm undercuts this narrative and may confuse the court about the nature of the competitive benefits Cascade expects to achieve.

We also flag a practical coordination concern. Any characterization of Pinnacle as a "failing" firm will be sensitive for Pinnacle's management, particularly Co-Founder and CEO Rajiv Chandravar and CFO Thomas Breck. Both individuals are expected to serve as fact witnesses at the PI hearing, and both may resist testimony that paints Pinnacle in such stark terms. Founder pride, concern about employee morale, and potential liability concerns (including securities law exposure if the merger does not close and Pinnacle's stock price is affected by courtroom characterizations of the company's viability) all counsel in favor of careful coordination with Diana Whitfield at Whitfield, Greer & Tanaka regarding the scope and tenor of any failing-firm-related testimony. We recommend discussing this topic at the next weekly joint defense coordination call.

V. Analysis of the "Weakened Competitor" / "Flailing Firm" Argument

While the traditional failing-firm defense is unavailable, the evidence of Pinnacle's competitive deterioration supports a distinct and powerful argument that the merger's anticompetitive potential is materially diminished because Pinnacle's future competitive significance is substantially less than its historical market share suggests. This section analyzes the evidence supporting the weakened-competitor argument in detail.

A. Pinnacle's Decelerating Growth

The most striking feature of Pinnacle's recent competitive trajectory is the dramatic deceleration of its GMV growth. Over the past three fiscal years, Pinnacle's YoY GMV growth rate has declined precipitously:

Several features of this trajectory are particularly noteworthy. First, the deceleration is not merely a one-year anomaly but a persistent and accelerating trend spanning three consecutive fiscal years. Pinnacle's growth rate declined by ten percentage points from FY2022 to FY2023 and by an additional nine percentage points from FY2023 to FY2024. If this trend continues — and the evidence discussed in subsequent sections suggests it will — Pinnacle's growth could approach zero or turn negative within one to two years.

Second, Pinnacle's revenue growth mirrors the GMV deceleration and is constrained by a stable take rate of approximately 16%. Because Pinnacle's primary revenue stream is commissions charged as a percentage of GMV, revenue growth is mechanically linked to GMV growth. The stability of the take rate limits Pinnacle's ability to offset GMV deceleration through pricing — raising the take rate would likely accelerate seller departures, while reducing it would compress margins further.

Third, and critically, Pinnacle's growth rate must be assessed in the context of the broader market. The overall U.S. e-commerce market generated approximately $757 billion in total GMV in 2024 and has been growing at approximately 12–14% YoY. Pinnacle's 9% GMV growth in FY2024 thus falls materially below the industry average. This means that Pinnacle is not merely growing more slowly — it is losing market share on an organic basis. Every quarter that Pinnacle grows below the market rate, its relative competitive position erodes further.

The competitive implications of this deceleration are particularly significant in the context of the FTC's proposed relevant market. The FTC alleges that Pinnacle holds a 30.1% share of "online marketplace platform services for third-party sellers in the United States." But if Pinnacle's growth rate has fallen below the industry average and continues to decelerate, that 30.1% share represents a snapshot of Pinnacle's historical position — not a reliable predictor of its future competitive significance. Just as the Supreme Court recognized in Severin Holdings that a coal company's depleted reserves made its historical production-based market share a misleading indicator of its future ability to compete, Pinnacle's decelerating growth makes its current market share a misleading indicator of its future competitive importance.

The competitive pressures driving Pinnacle's deceleration are both structural and firm-specific. On the structural side, the U.S. marketplace sector is maturing, and the intense growth that characterized the post-pandemic period (2020–2022) has given way to a more competitive environment in which established platforms compete vigorously for seller and buyer participation. On the firm-specific side, Pinnacle faces increasingly effective competition from Vertex Commerce Inc. (which holds a 35.7% share and continues to grow robustly), Nomad Shops LLC (14.6% share, with a strong brand identity among artisan and small-business sellers that directly competes with Pinnacle's core demographic), and new entrants including Brevity Social Commerce Inc. (launched 2023) and Trove Marketplace Inc. (launched 2024). We discuss these competitive dynamics in greater detail in Section V.C below.

B. Escalating Seller Churn

If decelerating GMV growth is the most visible symptom of Pinnacle's competitive weakening, escalating seller churn is the most ominous. Seller churn — the rate at which active sellers depart or become inactive on the platform over a given period — is a critical leading indicator of platform health in a two-sided marketplace, and Pinnacle's churn data reveals a deeply concerning trend.

A 21% annual seller churn rate means that Pinnacle is losing approximately one in every five active sellers each year. At 185,000 active sellers, this translates to approximately 38,850 sellers who departed or became inactive on the platform during FY2024. That Pinnacle's total active seller count has nonetheless continued to increase slightly — from approximately 175,000 in FY2022 to approximately 185,000 in FY2024 — indicates that the company has been acquiring new sellers at a rate sufficient to offset departures. But this replacement dynamic is unsustainable: the cost of acquiring new sellers is rising (as the most attractive sellers have already been solicited by competing platforms), and the quality of replacement sellers may be lower than that of departing sellers.

The sources of seller churn are varied but point consistently to the intensifying competitive pressure Pinnacle faces:

• Migration to Vertex Commerce. Vertex's 35.7% market share and extensive buyer base make it an attractive alternative for high-volume sellers seeking maximum transaction volume and exposure. Vertex has invested heavily in logistics infrastructure and AI-driven seller tools that reduce seller costs and improve the selling experience. Sellers who previously maintained a presence on both Vertex and Pinnacle are increasingly concentrating their activity on Vertex and reducing or eliminating their Pinnacle presence.

• Migration to Nomad Shops. Nomad Shops has cultivated a strong brand identity among artisan, handmade, and small-business sellers — the very demographic that formed the core of Pinnacle's original value proposition. Nomad's seller-centric tools, lower take rates for qualifying sellers, and marketing focused on the artisan community have attracted sellers away from Pinnacle in the home goods, artisanal products, and specialty foods categories that Pinnacle historically dominated.

• Direct-to-Consumer Channels. An increasing number of sellers are investing in their own direct-to-consumer e-commerce capabilities, using tools provided by companies such as Dunmore Services Inc. and Granite Harbor Services Inc. to establish independent online storefronts. This trend reduces sellers' dependence on marketplace platforms generally and diminishes the pool of sellers available to Pinnacle.

• Social Commerce. The emergence of social commerce platforms — most notably Brevity Social Commerce Inc. (launched 2023 in Los Angeles) — represents a new competitive paradigm in which commerce is integrated directly into social media environments. Sellers, particularly in fashion and lifestyle categories, are finding that social commerce platforms offer superior buyer engagement and lower customer acquisition costs. Pinnacle has been slow to adapt to this trend, and sellers are shifting activity accordingly.

The multi-homing dynamic further compounds the significance of the churn data. Many online sellers list their products on multiple marketplace platforms simultaneously, allocating their time, inventory, and marketing spend across platforms based on relative returns. In a multi-homing environment, churn does not necessarily mean that a seller exits e-commerce entirely; more commonly, it means the seller drops one or more platforms while retaining others. The acceleration of Pinnacle's churn rate suggests that sellers who previously maintained a Pinnacle presence as part of a multi-platform strategy are now choosing to drop Pinnacle — indicating that Pinnacle is increasingly the marginal platform in sellers' multi-homing calculus.

The impact of seller churn on Pinnacle's competitive position is amplified by the cross-side network effects inherent in a two-sided marketplace. When sellers depart Pinnacle, the platform's product selection narrows. A narrower product selection reduces consumer utility, which in turn reduces consumer traffic to the platform. Reduced consumer traffic diminishes the returns to remaining sellers, who then face an incentive to redirect their own activity to more heavily trafficked platforms. This creates a negative feedback loop — a vicious cycle that can be extremely difficult to arrest once it reaches a critical threshold. While we do not assert that Pinnacle has yet entered a terminal "death spiral," the trajectory of the data suggests that the company may be approaching a tipping point beyond which the feedback dynamic becomes self-reinforcing.

We have requested that Brindoval Analytics LLC — specifically Dr. Priya Ramanathan and Dr. Lucas Engström — obtain access to Pinnacle's internal seller-level data to model churn drivers in greater detail and to quantify the expected trajectory of seller departures absent the merger. This data will be critical for Dr. Ramanathan's expert report (due August 18, 2025) and for the testimony we intend to present at the PI hearing. We are coordinating with Kenneth Oshiro at Whitfield, Greer & Tanaka on data access under the Joint Defense and Common Interest Agreement executed July 1, 2025.

C. Competitive Pressures and Market Entry

Pinnacle's deceleration and seller churn must be understood in the context of the broader competitive landscape, which has evolved significantly since Pinnacle's founding in 2014 and its IPO in 2020. The market for online marketplace platform services is increasingly crowded, and Pinnacle faces competitive threats from multiple directions.

Vertex Commerce Inc. (San Jose, CA). Vertex is the largest platform in the FTC's alleged relevant market, holding a 35.7% market share by GMV. The company is well-capitalized, publicly traded, and has invested aggressively in logistics infrastructure (including a network of fulfillment centers), artificial intelligence-driven seller tools, and consumer-facing features that enhance the shopping experience. Vertex's scale advantages are significant: its large buyer base attracts sellers, and its extensive seller base attracts buyers, creating the kind of virtuous network-effects cycle that Pinnacle has struggled to maintain. Vertex is gaining market share from Pinnacle, particularly among high-volume sellers who prioritize reach and transaction volume.

Nomad Shops LLC (Brooklyn, NY). Nomad holds a 14.6% market share and has established itself as the platform of choice for artisan, handmade, and small-business sellers. Nomad's brand resonates with consumers who value authenticity, craftsmanship, and the "shop small" ethos. Critically, Nomad's target seller demographic overlaps substantially with Pinnacle's core seller base. Pinnacle's early advantage in categories like artisanal products, specialty foods, and handmade home goods — the categories on which the company built its reputation and differentiated itself from Vertex — is being eroded by Nomad's focused competitive strategy. As Nomad continues to invest in seller tools, marketing, and category expansion, Pinnacle's historical competitive moat in these categories grows narrower.

Brevity Social Commerce Inc. (Los Angeles, CA). Brevity launched in 2023 and represents a new competitive paradigm in online commerce. The platform integrates commerce directly into social media environments, leveraging influencer partnerships, user-generated content, and social graph data to drive discovery and purchases. Brevity's model is particularly appealing to younger consumers (Gen Z and younger Millennial demographics) and to sellers in fashion, beauty, and lifestyle categories. Pinnacle has been slow to adopt social commerce features and has lost ground among sellers who find Brevity's model more effective at driving engagement and sales. While Brevity's current market share is small (it falls within the "all others" category at 11.4% combined), its growth trajectory and disruptive potential merit close attention.

Trove Marketplace Inc. (Chicago, IL). Trove launched in 2024 and has differentiated itself through a technology-first approach, offering lower take rates to sellers and a streamlined onboarding process. Trove's competitive strategy is explicitly designed to attract sellers from established platforms by reducing the commission burden that sellers face. While Trove is in its early stages and its long-term viability is uncertain, its entry is indicative of the dynamism and contestability of the marketplace sector.

These competitive developments are relevant to the weakened-competitor analysis in two ways. First, they explain why Pinnacle's competitive position is deteriorating. Pinnacle is not weakening in a vacuum; it is weakening because it faces increasingly effective competition from established rivals (Vertex, Nomad) and innovative new entrants (Brevity, Trove). Second, they demonstrate that the market is dynamic and contestable — a point that reinforces the ease-of-entry defense and suggests that competitive conditions will continue to evolve regardless of whether the Cascade-Pinnacle merger proceeds.

It is also worth noting that the FTC's own complaint acknowledges Vertex Commerce's 35.7% market share — larger than Pinnacle's 30.1% and substantially larger than the combined Cascade-Pinnacle share of 38.3%. Under the FTC's own market definition, Vertex would remain the largest platform post-merger and would continue to provide a strong competitive constraint on the combined entity. This fact, combined with the evidence of Pinnacle's weakening, significantly diminishes the merger's competitive significance.

D. Financial and Operational Indicators of Weakening

Beyond the top-line GMV and seller churn metrics, additional financial and operational indicators point to Pinnacle's diminishing competitive vitality.

Margin Compression. Pinnacle's operating margins have compressed over the past several fiscal years. While we do not yet have access to the granular financial data necessary to quantify the margin decline with precision — a request for this data is pending with Pinnacle's counsel — the general trend is apparent from Pinnacle's public SEC filings and investor presentations. Margin compression reflects a combination of factors: rising seller acquisition costs (as Pinnacle must spend more to replace churning sellers), increasing investment in logistics and technology (necessary to maintain competitive parity with Vertex), and the inability to raise the take rate without accelerating seller departures. As margins compress, Pinnacle's ability to fund innovation and competitive investment is diminished, creating a further drag on the company's competitive trajectory.

Stock Price Decline. Pinnacle's stock price has declined significantly from its post-IPO highs. The company completed its IPO on September 18, 2020, at a time of significant investor enthusiasm for e-commerce platforms (buoyed in part by the COVID-19 pandemic's acceleration of online shopping trends). By March 7, 2025 — the last trading day before the merger was leaked to the market — Pinnacle's stock had declined to $22.30 per share. While stock price movements reflect a multitude of factors (including macroeconomic conditions, interest rate changes, and sector-wide valuation compression), the sustained decline in Pinnacle's stock price is consistent with the broader evidence of the company's weakening competitive position and reflects market skepticism about Pinnacle's standalone trajectory.

R&D Investment. Pinnacle's R&D spending as a percentage of revenue may be declining or stagnant, limiting the company's ability to innovate and maintain competitive parity with rivals who are investing more aggressively in platform technology, AI capabilities, and seller tools. We are working to confirm this hypothesis with data from Pinnacle's audited financial statements (audited by Kessler Fong Accounting Group LLP of Dallas, Texas) and internal financial reports. If confirmed, this trend would provide additional support for the argument that Pinnacle's competitive capabilities are diminishing.

Key Talent Departures. We have received anecdotal reports of departures by key personnel from Pinnacle's engineering and product development teams. In the technology sector, talent departures — particularly of senior engineers, product managers, and data scientists — can be both a symptom and a cause of competitive decline. Talented employees are attracted to companies with strong growth trajectories and innovative cultures; when a company's competitive position deteriorates, its most talented employees are often the first to leave, depriving the company of the human capital necessary to reverse the decline. We are working to confirm these reports through diligence and coordination with Whitfield, Greer & Tanaka.

Potential Testimony of Thomas Breck. Thomas Breck, Pinnacle's CFO, may be an effective witness on these financial and operational indicators at the PI hearing. Breck can speak credibly to the company's financial trajectory, the competitive pressures it faces, and the challenges of sustaining growth and investment in an increasingly competitive marketplace environment. His testimony can contextualize the quantitative data — the GMV deceleration, the margin compression, the churn metrics — within a narrative of competitive weakening, without requiring him to characterize Pinnacle as a "failing" firm. This is an important distinction: the weakened-competitor argument does not require any Pinnacle witness to testify that the company is failing or on the verge of collapse. It requires only that the evidence show Pinnacle's competitive significance is declining — a characterization that Breck should be willing to support.

E. Application of the *Severin Holdings* and *Arch Coal* Frameworks

The evidence of Pinnacle's competitive deterioration maps directly onto the analytical frameworks established by the Supreme Court in Severin Holdings and applied by the D.C. district court in Arch Coal.

Under Severin Holdings, the relevant inquiry is whether market share data accurately reflects a firm's "future ability to compete." The Supreme Court held that where a firm's competitive resources are depleted or declining, historical market shares overstate the anticompetitive effect of a merger involving that firm. The Court emphasized that Section 7 of the Clayton Act is concerned with the probable future effects of a merger on competition, not merely with the mathematical rearrangement of historical market share figures. Where the evidence demonstrates that a firm's competitive position is eroding — for reasons independent of the merger — the market share statistics on which the government relies lose much of their probative force.

Under Arch Coal, the D.C. district court applied the Severin Holdings framework in denying the FTC's motion for preliminary injunction against a coal industry merger. The court credited the defendants' evidence that the target firm's competitive significance was declining — that its reserves, contracts, and market position were deteriorating — and concluded that the FTC had not established a likelihood of success on the merits. Critically, the court reached this conclusion without requiring the defendants to satisfy the strict three-pronged failing-firm defense. The weakened-competitor analysis operated independently as a basis for rebutting the FTC's prima facie case.

Applied to Pinnacle, these frameworks support the following argument:

Pinnacle's 30.1% market share — the figure on which the FTC's concentration analysis and competitive effects theory depend — overstates Pinnacle's future competitive significance because:

1. Growth is decelerating and has fallen below the industry average. Pinnacle's GMV growth declined from 28% YoY in FY2022 to 9% YoY in FY2024, while the broader U.S. e-commerce market grew at 12–14% YoY. This means Pinnacle is losing market share on an organic basis and is likely to continue doing so.

2. Seller churn is accelerating, eroding the two-sided network effects that sustain platform competitiveness. Pinnacle's seller churn rate nearly doubled from 12% in FY2022 to 21% in FY2024, indicating that sellers are increasingly choosing to leave the platform in favor of competitors. In a two-sided marketplace, seller departures reduce product selection, which reduces buyer traffic, which further reduces seller returns — a negative feedback dynamic that accelerates competitive erosion.

3. Competitors and new entrants are gaining ground. Vertex Commerce (35.7% share) continues to grow robustly, Nomad Shops (14.6% share) is directly eroding Pinnacle's position in its core artisan and specialty categories, and new entrants like Brevity Social Commerce and Trove Marketplace are introducing innovative competitive models that Pinnacle has been slow to adopt.

4. The trajectory is clear and is likely to continue. The data suggest that Pinnacle's market share will continue to erode absent the merger. The deceleration in growth and the acceleration in churn are not one-time events but persistent, multi-year trends driven by structural competitive forces.

The implication for the FTC's case is profound. Even if the FTC's narrow market definition ("online marketplace platform services for third-party sellers in the United States") is accepted for purposes of analysis, the merger's competitive impact is substantially overstated. One of the merging parties — the larger of the two, in fact — is a weakening player whose market share would decline regardless of the transaction. The concentration statistics on which the FTC relies (post-merger HHI of 2,856, delta of 495) are premised on the assumption that Pinnacle will maintain its current 30.1% market share. If that share is projected to decline significantly — as the evidence strongly suggests — the forward-looking HHI delta would be materially smaller, and the merger would fall closer to or below the presumption thresholds in the Merger Guidelines.

This argument dovetails with — and reinforces — the broader market definition argument presented in the Market Definition Analysis Memorandum (dated July 10, 2025). If the relevant market is properly defined as "all e-commerce retail" rather than the FTC's artificially narrow "online marketplace platform services" market, the combined Cascade-Pinnacle share is approximately 7.3% of total U.S. e-commerce GMV of $757 billion. At that level of concentration, the weakened-competitor evidence becomes almost superfluous — the merger would not raise competitive concerns under any plausible analytical framework. But even under the FTC's narrow market definition, the weakened-competitor evidence provides a strong independent basis for challenging the Commission's prima facie case.

F. Counterarguments and Risks

Any credible analysis of a defense theory must confront the strongest counterarguments the opposing party is likely to advance. We identify the following anticipated FTC responses and associated risks.

FTC Response: Pinnacle Is Not Failing and Remains a Significant Competitive Force. The FTC will argue that Pinnacle, with $11.4 billion in GMV, $1.82 billion in net revenue, and 185,000 active sellers, is far from a weakened competitor. The Commission will emphasize that deceleration is not decline and that Pinnacle remains one of the two largest platforms in the alleged relevant market. The FTC will note that Pinnacle continues to acquire new sellers (its total active seller count increased from approximately 175,000 to approximately 185,000 over the 2022–2024 period), continues to grow (albeit at a slower rate), and continues to generate positive revenue and earnings.

This argument is the strongest the FTC will advance on this point, and we must be careful not to overstate the weakened-competitor narrative. Our argument is not that Pinnacle is irrelevant or that it has already ceased to be a competitive force. Our argument is more nuanced: that Pinnacle's historical market sha

INTERNAL MEMORANDUM
July 20, 2025
I. Executive Summary
This memorandum assesses whether Pinnacle Market Group Inc. ("Pinnacle" or "PMG") qualifies for the traditional failing-firm defense under Section 7 of the Clayton Act, 15 U.S.C. § 18, and, alternatively, whether Pinnacle's deteriorating competitive position supports a "weakened competitor" or "flailing firm" argument that materially diminishes the anticompetitive potential of Cascade Retail Holdings Inc.'s ("Cascade" or "CRH") proposed $4.7 billion acquisition of Pinnacle. The analysis is conducted in the context of the Federal Trade Commission's ("FTC" or "Commission") challenge to the merger, presently pending before the Honorable Richard A. Johannsen in the Western District of Washington and before the Commission on an administrative complaint.
Bottom-Line Conclusion. Pinnacle does not satisfy the strict three-pronged failing-firm defense. Specifically, Pinnacle is not facing imminent business failure: it generated $11.4 billion in gross merchandise volume ("GMV") and $1.82 billion in net revenue in FY2024, maintains approximately 185,000 active sellers, and carried a pre-announcement market capitalization of approximately $3.9 billion. The company has not exhausted reorganization alternatives, has not engaged restructuring advisors, and has not filed for bankruptcy. Moreover, the sale process conducted by Ridgeline Capital Partners generated interest from multiple potential acquirers, and the record does not clearly establish that no alternative, less-anticompetitive purchaser existed. Accordingly, none of the three traditional prongs of the failing-firm defense can be established to the satisfaction of a court.
However, Pinnacle's competitive trajectory — marked by dramatically decelerating GMV growth (from 28% year-over-year ("YoY") in FY2022 to 9% YoY in FY2024) and sharply rising seller churn (from 12% in FY2022 to 21% in FY2024) — supports a powerful alternative argument that the merger's anticompetitive potential is materially reduced because Pinnacle's future competitive significance is substantially diminished. Under the analytical framework established by the Supreme Court in United States v. Fenmore Industries, 415 U.S. 486 (1974), and applied by the D.C. district court in FTC v. Arch Coal, Inc., 329 F. Supp. 2d 109 (D.D.C. 2004), Pinnacle's historical 30.1% market share (under the FTC's proposed relevant market) significantly overstates the company's future ability to compete. This evidence directly undermines the FTC's prima facie case and reduces both the likely magnitude of any anticompetitive effect and the forward-looking concentration metrics on which the Commission relies.
Recommendation. We should pursue the weakened/flailing firm argument as a secondary defense pillar alongside the primary market definition and efficiencies defenses in the Memorandum in Opposition to the FTC's Motion for Preliminary Injunction (due August 11, 2025). The strict failing-firm defense should be reserved in our pleadings for completeness — it has already been asserted as an affirmative defense in Cascade's answer — but it should not be featured prominently at the September 8, 2025 preliminary injunction hearing before Judge Johannsen. Leading with an aggressive failing-firm defense that cannot be sustained risks undermining Cascade's broader credibility and may be perceived as inconsistent with the procompetitive narrative that frames our primary defense theories.
This memorandum should be read in conjunction with the Efficiencies Defense Memorandum (dated July 18, 2025, from A. Liu to E. Nguyen), the Market Definition Analysis Memorandum (dated July 10, 2025, from E. Nguyen to Howard Bellamy), and the Memorandum on the Preliminary Injunction Standard Under Section 13(b) (dated July 5, 2025, from E. Nguyen to H. Bellamy).
II. Background
A. Transaction Overview
On March 14, 2025, Cascade Retail Holdings Inc. and Pinnacle Market Group Inc. executed an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which CRH Merger Sub Inc., a wholly owned subsidiary of Cascade formed for the purpose of the transaction, will merge with and into Pinnacle, with Pinnacle surviving as a wholly owned subsidiary of Cascade. The transaction is structured as an all-cash reverse triangular merger. The transaction was publicly announced on March 17, 2025, when Cascade and Pinnacle each filed a Form 8-K with the Securities and Exchange Commission disclosing the material terms of the Merger Agreement.
The aggregate consideration payable to Pinnacle shareholders is approximately $4.7 billion, calculated as $26.85 per share multiplied by 175,047,319 shares of Pinnacle common stock outstanding. This per-share price represents a premium of approximately 20.4% over Pinnacle's unaffected closing price of $22.30 on March 7, 2025 — the last trading day before market speculation regarding a potential transaction began to affect Pinnacle's stock price.
Cascade is financing the transaction through a combination of $1.9 billion in cash on hand and $2.8 billion in borrowings under a senior secured Term Loan B facility committed by Whitmore National Bank, N.A. pursuant to a commitment letter dated March 12, 2025. In addition, Cascade has secured a $500 million revolving credit facility, which is expected to remain undrawn at closing and is available for post-closing working capital purposes and integration expenditures.
Pinnacle retained Ridgeline Capital Partners, a San Francisco-based investment bank, as its financial advisor for the transaction. Nadine Vasquez, Managing Director at Ridgeline, led the engagement. Cascade retained Mercer Hollis & Co. of New York as its financial advisor. Transaction counsel for Cascade is Harmon Ridgeway & Strauss LLP, with Phillip Strauss serving as lead M&A partner.
The parties filed their pre-merger notification under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, 15 U.S.C. § 18a, on April 2, 2025 (Transaction No. HSR-20250402-0347). The FTC issued a Second Request for additional information and documentary material on May 7, 2025 (File No. 251-0089). Cascade certified substantial compliance with the Second Request on June 10, 2025.
The Merger Agreement provides for an outside date of March 14, 2026, subject to extension to June 14, 2026 if the sole unsatisfied closing condition as of March 14, 2026 is the receipt of antitrust clearance. The agreement further provides for a reverse termination fee of $282 million (approximately 6% of deal value), payable by Cascade to Pinnacle in the event the transaction fails to close due to the failure to obtain required antitrust approvals. Pinnacle is obligated to pay a company termination fee of $164.5 million (approximately 3.5% of deal value) if it terminates the Merger Agreement to accept a superior proposal or under certain other circumstances specified in the agreement.
B. FTC Challenge
On June 20, 2025, the FTC issued an administrative complaint (Docket No. 9438) challenging the proposed acquisition under Section 7 of the Clayton Act, 15 U.S.C. § 18. Three days later, on June 23, 2025, the Commission filed a complaint in the United States District Court for the Western District of Washington, Seattle Division, seeking a temporary restraining order and preliminary injunction pursuant to Section 13(b) of the FTC Act, 15 U.S.C. § 53(b), to prevent consummation of the merger pending resolution of the administrative proceeding. The district court action was assigned Case No. 2:25-cv-01087-RAJ and is before the Honorable Richard A. Johannsen.
The Commission authorized the filing of the complaint by a 3–2 vote, reflecting significant internal disagreement regarding the merits of the challenge. The identity and reasoning of the dissenting commissioners may be relevant to our defense strategy, and their dissenting statements — to the extent they have been made public — should be reviewed for language that may support the weakened-competitor argument or otherwise undercut the majority's theory of competitive harm.
The FTC's litigation team is led by Claire Dunmore, Lead Trial Attorney in the Bureau of Competition's Mergers IV Division. She is supported by Samuel Ortega, Senior Trial Counsel, and Rebecca Yun, Staff Attorney. Dr. Nathaniel Hargrove of the Bureau of Economics serves as the staff economist for the matter.
The FTC alleges that the relevant product market is "online marketplace platform services for third-party sellers in the United States." Within this market, the Commission alleges the following market shares based on GMV:
Based on these market shares, the FTC calculates a pre-merger Herfindahl-Hirschman Index ("HHI") of 2,361, a post-merger HHI of 2,856, and a delta (increase) of 495. These figures place the transaction well above the presumption thresholds established in the 2023 Merger Guidelines, which treat mergers resulting in a post-merger HHI above 2,500 with a delta above 200 as presumptively anticompetitive.
Judge Johannsen has scheduled the evidentiary hearing on the FTC's motion for preliminary injunction to begin September 8, 2025, with an estimated duration of five court days. Cascade's opposition to the preliminary injunction motion is due August 11, 2025.
C. Pinnacle Market Group — Company Profile
Pinnacle Market Group Inc. is a Delaware corporation headquartered at 500 East 6th Street, Suite 800, Austin, Texas 78701. The company was founded in 2014 by Rajiv Chandravar (Co-Founder and Chief Executive Officer) and Lena Kowalski (Co-Founder and Chief Product Officer). Thomas Breck serves as Chief Financial Officer, and Anita Suresh serves as General Counsel. Pinnacle completed its initial public offering on the Nasdaq Stock Market on September 18, 2020, under the ticker symbol PMGI.
Pinnacle operates an online marketplace platform that connects independent sellers with consumers across a range of product categories, including home goods, artisanal products, specialty foods, fashion, and consumer electronics. The platform serves as an intermediary, providing sellers with storefronts, payment processing, search and discovery tools, and logistics integration while offering consumers a curated marketplace experience. Pinnacle generates revenue primarily through commissions on transactions completed on its platform, commonly referred to as a "take rate."
For FY2024 (the fiscal year ending December 31, 2024), Pinnacle reported approximately 185,000 active sellers, $11.4 billion in GMV, and $1.82 billion in net revenue, reflecting a take rate of approximately 16%. The company's pre-announcement market capitalization — calculated based on 175,047,319 shares outstanding and the unaffected closing price of $22.30 as of March 7, 2025 — was approximately $3.9 billion.
Pinnacle's independent auditor is Kessler Fong Accounting Group LLP of Dallas, Texas. In connection with this litigation, Pinnacle is represented by Whitfield, Greer & Tanaka LLP, with Diana Whitfield (Lead Partner) and Kenneth Oshiro (Senior Associate) based in Austin, Texas, leading the defense effort on Pinnacle's behalf.
III. Legal Framework
A. The Traditional Failing-Firm Defense
The failing-firm defense has its origins in the Supreme Court's decision in International Shoe Co. v. FTC, 280 U.S. 291 (1930), in which the Court recognized that a merger with a failing company is not properly condemned under the antitrust laws because the competitive conditions in the market would deteriorate regardless of whether the merger proceeds. The rationale underlying the defense is fundamentally one of causation: if the acquired firm would exit the market irrespective of the merger, then the merger does not cause the diminution of competition that Section 7 of the Clayton Act is designed to prevent.
The modern articulation of the failing-firm defense was established by the Supreme Court in Citizen Publishing Co. v. United States, 394 U.S. 131 (1969). Under Citizen Publishing, the defense requires the merging parties to establish three elements:
1. Imminent Business Failure. The acquired firm faces the grave probability of a business failure. Its resources must be so depleted and its prospects for rehabilitation so remote that the firm is on the verge of financial collapse. It is not sufficient that the firm is merely experiencing competitive difficulties, declining profitability, or adverse market trends; the standard requires a showing of imminent insolvency or the functional equivalent thereof.
2. No Reasonable Prospect of Successful Reorganization. The firm has no reasonable prospect of successfully reorganizing its affairs, including through proceedings under Chapter 11 of the Bankruptcy Code. This prong requires the firm to demonstrate that reorganization — whether through bankruptcy, operational restructuring, asset sales, or other alternatives — would not preserve the firm as a viable competitive entity.
3. No Alternative Less-Anticompetitive Purchaser. The firm has made good-faith but unsuccessful efforts to elicit reasonable alternative offers from other potential purchasers that would pose a less severe threat to competition than the proposed acquirer. This prong ensures that the acquired firm has exhausted less anticompetitive transactional alternatives before resorting to a merger that raises significant competitive concerns.
The Department of Justice and the Federal Trade Commission have recognized the failing-firm defense in successive iterations of the Horizontal Merger Guidelines. The current Guidelines acknowledge the defense but describe it as "rarely" applicable, emphasizing that all three prongs must be satisfied and that the burden of proof falls squarely on the merging parties. The Guidelines further note that a company is not considered to be "failing" merely because it has experienced declining revenues, reduced profitability, or competitive difficulties; rather, the defense contemplates a firm that is genuinely unable to meet its financial obligations in the near term.
The allocation of the burden of proof to the defendants is well-established and has been applied consistently across federal circuits. The applicable standard of proof is somewhat less settled. Several circuits have required clear and convincing evidence, while others apply a preponderance-of-the-evidence standard. For present purposes, we note that this case is venued in the Western District of Washington and that the Ninth Circuit has not definitively resolved the question. However, under either standard, the evidence must be substantial, and courts have uniformly applied the defense with considerable strictness.
Key precedents illustrating the defense's demanding requirements include FTC v. Warner Communications, in which the court emphasized the high evidentiary bar the defense imposes, and California v. Sutter Health System, in which the court applied the defense narrowly and found it unsatisfied despite evidence of the acquired firm's financial difficulties. The consistent theme in the case law is that the failing-firm defense is an exceptional doctrine that applies only in extraordinary circumstances.
B. The "Weakened Competitor" / "Flailing Firm" Alternative
Distinct from the strict failing-firm defense is the "weakened competitor" or "flailing firm" argument — a broader analytical framework that does not require a showing of imminent business failure but instead challenges the inferential value of historical market share data as a predictor of future competitive significance. The weakened-competitor argument operates within the competitive effects analysis rather than as a standalone affirmative defense. Its core contention is that where one of the merging firms is a declining competitive force — losing customers, market share, or competitive capabilities — the merger's likely anticompetitive effects are diminished because the acquired firm's historical market share overstates its future importance to competition.
The Horizontal Merger Guidelines recognize this concept as a relevant factor in assessing competitive effects. The Guidelines observe that a firm's current market position may not reflect its future competitive significance if the firm is experiencing a sustained decline in competitive vitality. In such circumstances, the Guidelines contemplate that the merger's likely effect on competition may be less than what concentration statistics alone would suggest.
The seminal precedent for this analytical approach is the Supreme Court's decision in United States v. Fenmore Industries, 415 U.S. 486 (1974). In Severin Holdings, the Court evaluated a merger between coal producers and held that the acquired firm's historical market share — measured by past production — was a misleading indicator of its future competitive significance because the firm's coal reserves were largely committed under long-term contracts, leaving it with little capacity to compete for new business. The Court articulated the principle that the proper inquiry under Section 7 is not the firm's past competitive position but rather its "future ability to compete." Where evidence demonstrates that a firm's competitive resources are depleted or declining, market share data drawn from historical periods will overstate the merger's competitive impact.
The Severin Holdings framework was applied with particular force in FTC v. Arch Coal, Inc., 329 F. Supp. 2d 109 (D.D.C. 2004). In Arch Coal, the FTC sought a preliminary injunction against a coal industry merger, and the court denied the request in part because the evidence demonstrated that the target firm's competitive position was declining. The court credited the defendants' showing that the target's market share overstated its future competitive significance and concluded that the FTC had not established a likelihood of success on the merits. Critically, the Arch Coal court reached this conclusion without requiring the defendants to satisfy the strict three-pronged failing-firm defense. The weakened-competitor analysis operated independently as a challenge to the FTC's prima facie case.
Additional support for the weakened-competitor framework can be found in FTC v. Tronox Ltd., where the court applied a weakened-competitor analysis in assessing the future competitive significance of the target firm. While the court in Tronox ultimately credited the FTC's challenge, the decision acknowledged the analytical validity of the weakened-competitor framework and engaged with the defendants' evidence on the point.
The weakened-competitor argument does not require the merging parties to satisfy the three prongs of the failing-firm defense. It is not a substitute for or lesser version of the failing-firm defense but rather a distinct analytical tool that challenges the FTC's reliance on historical market share data. Courts considering the weakened-competitor argument have examined a range of indicators, including:
• Declining sales volumes and revenue
• Loss of customers, suppliers, or — in the marketplace context — sellers
• Departure of key personnel, particularly in technology, engineering, and senior leadership roles
• Technological obsolescence or failure to keep pace with competitors' innovations
• Inability to attract new capital investment or rising cost of capital
• Competitive entry by stronger or more innovative rivals
• Erosion of the firm's competitive advantages or differentiating features
The application of the weakened-competitor framework to two-sided marketplace platforms presents a particularly compelling dynamic. In a two-sided marketplace, the platform's value to each side of the market is a function of participation on the other side: sellers are attracted by the presence of a large and active buyer base, and buyers are attracted by a broad and diverse selection of sellers and products. These cross-platform network effects create a virtuous cycle when the platform is growing — more sellers attract more buyers, which in turn attracts more sellers. However, the same dynamic operates in reverse when the platform is contracting. Declining seller participation reduces product selection, which reduces buyer traffic, which further diminishes seller returns and accelerates seller departures. This negative feedback loop — sometimes described as a "death spiral" dynamic — means that the loss of competitive vitality in a marketplace platform can be self-reinforcing and difficult to reverse, amplifying the significance of the weakened-competitor evidence.
It should be noted that the weakened-competitor argument is most effective when deployed in combination with other defense theories. Where the defendants can also challenge the FTC's market definition (demonstrating that the relevant market is broader than the FTC alleges), establish cognizable merger-specific efficiencies, and show ease of competitive entry, the weakened-competitor evidence provides an additional — and often independently sufficient — basis for rebutting the government's prima facie case.
C. Relationship to Section 13(b) Preliminary Injunction Standard
The procedural posture of this matter warrants particular attention to the standard governing the FTC's motion for preliminary injunction. Under Section 13(b) of the FTC Act, 15 U.S.C. § 53(b), the Commission is entitled to a preliminary injunction upon demonstrating (1) a likelihood that it will succeed on the merits of its Section 7 claim in the administrative proceeding, and (2) that the equities tip in favor of injunctive relief. This standard is less demanding than the traditional four-factor preliminary injunction test applied in private litigation; in particular, the FTC is not required to demonstrate irreparable harm as a separate element. Nonetheless, the court retains discretion to weigh the equities, including the public interest in permitting or prohibiting the transaction.
The weakened-competitor evidence is relevant to both prongs of the Section 13(b) analysis. With respect to the likelihood of success, the evidence directly undermines the FTC's ability to prove a Section 7 violation. The Commission's case rests on the premise that the merger of two significant marketplace competitors — yielding a combined market share of 38.3% — will substantially lessen competition. But if Pinnacle's 30.1% share is declining and likely to continue declining, the merger does not eliminate a competitive force of the magnitude the FTC alleges. The forward-looking competitive significance of the acquired firm is materially less than its historical market share suggests, and the FTC's prima facie case is correspondingly weaker.
With respect to the equities, the weakened-competitor evidence demonstrates that blocking the merger may not serve the public interest. If Pinnacle continues to decline independently — losing sellers, losing market share, and potentially entering a negative-feedback-loop dynamic — the ultimate result for consumers and sellers may be worse than permitting the merger to proceed. Consumers face a diminished marketplace experience as Pinnacle's product selection narrows, and sellers face reduced returns as Pinnacle's buyer traffic declines. The merger offers an alternative future in which Cascade's resources and infrastructure are deployed to stabilize and revitalize Pinnacle's marketplace, preserving competitive options for consumers and sellers. This equity consideration should be presented to Judge Johannsen as a complement to the merits arguments.
For a more detailed treatment of the Section 13(b) standard and its application to the facts of this case, we refer to the Memorandum on the Preliminary Injunction Standard Under Section 13(b) (dated July 5, 2025, from Elliot Nguyen to Howard Bellamy).
IV. Analysis of the Traditional Failing-Firm Defense as Applied to Pinnacle
A. Prong 1: Imminent Business Failure
Assessment: NOT MET.
The first prong of the failing-firm defense requires a showing that the acquired firm faces the "grave probability of a business failure" — that its resources are so depleted and its prospects for rehabilitation so remote that it is on the verge of ceasing to operate as a going concern. This prong sets an extraordinarily high bar, and Pinnacle does not clear it.
Pinnacle's FY2024 financial results, while reflecting significant deceleration from prior years, do not remotely suggest imminent business failure. The company generated $11.4 billion in GMV and $1.82 billion in net revenue during FY2024. It maintained approximately 185,000 active sellers on its platform and continued to process millions of consumer transactions. While operating margins have compressed — a trend we discuss in greater detail in Section V.D below — the company remains profitable and is not generating negative cash flow on an overall basis. Pinnacle is not insolvent, is not in default on any material financial obligations, and is not unable to meet its liabilities as they come due.
The company's pre-announcement market capitalization of approximately $3.9 billion further undermines any claim of imminent failure. The public equity markets — while imperfect — reflect the consensus assessment of informed investors regarding a company's financial viability and future prospects. A company valued at nearly $4 billion by the public markets is not, by any reasonable measure, on the brink of business failure.
It is true that Pinnacle's growth has decelerated dramatically, from 28% YoY GMV growth in FY2022 to 9% YoY in FY2024. This deceleration is significant and forms the foundation of our weakened-competitor argument. But deceleration is not decline, and decline is not failure. Pinnacle is still growing — albeit slowly and below the industry average — and growth, even diminished growth, is fundamentally inconsistent with the concept of imminent business failure.
The FTC will undoubtedly argue that a company generating $1.82 billion in annual revenue, supporting 185,000 active sellers, and carrying a $3.9 billion market capitalization cannot credibly claim to be on the verge of failure. This argument has substantial force, and we would be ill-advised to contest it aggressively. Attempting to portray Pinnacle as imminently failing would lack evidentiary support and would invite skepticism from Judge Johannsen at a critical juncture in the proceedings.
Conclusion on Prong 1: Pinnacle is not on the verge of imminent business failure. This prong of the failing-firm defense is not satisfied.
B. Prong 2: Inability to Reorganize Successfully
Assessment: NOT MET.
The second prong requires a showing that the acquired firm has no reasonable prospect of successful reorganization, including through Chapter 11 proceedings. The purpose of this prong is to ensure that the acquired firm has explored all viable alternatives to a potentially anticompetitive merger before invoking the failing-firm defense as a justification for the transaction.
There is no evidence in the record that Pinnacle has explored or is unable to pursue reorganization. The company has not filed for bankruptcy, has not engaged restructuring advisors (so far as our diligence has revealed), and continues to operate its marketplace platform in the ordinary course of business. Pinnacle has not announced layoffs, facility closures, or other operational restructuring measures of the type that would ordinarily precede or accompany a reorganization effort.
Moreover, Pinnacle retains meaningful financial resources that could be deployed to fund a turnaround strategy. The company has cash reserves on its balance sheet, access to its existing credit facilities, and publicly traded equity that could be used to raise additional capital. Pinnacle's stock, while trading at a discount from its post-IPO highs, remains actively traded on the Nasdaq Stock Market and could serve as a basis for secondary offerings or other capital-raising transactions.
We also note that Lena Kowalski, Pinnacle's Co-Founder and Chief Product Officer, has reportedly spearheaded internal product redesign initiatives aimed at stemming seller churn and improving platform competitiveness. While these initiatives have not yet reversed the negative trends — seller churn continued to rise in FY2024 — the existence of internal turnaround efforts undercuts any argument that reorganization is not a reasonable prospect. The FTC would point to these very initiatives as evidence that Pinnacle has viable alternatives to the merger.
Conclusion on Prong 2: This prong is not satisfied. Pinnacle has not exhausted — or even seriously explored — reorganization alternatives, and its financial position permits such exploration.
C. Prong 3: No Alternative Less-Anticompetitive Purchaser
Assessment: LIKELY NOT MET (but the evidence is more nuanced than the first two prongs).
The third prong requires a showing that the acquired firm made good-faith but unsuccessful efforts to elicit reasonable alternative offers from purchasers that would pose a less severe threat to competition. This prong is designed to ensure that the acquired firm has not simply accepted the most lucrative bid without regard to the antitrust implications, and that no less anticompetitive alternative exists.
The facts relating to this prong are more nuanced than those relating to the first two prongs. Under the Merger Agreement, Pinnacle conducted a sale process advised by Ridgeline Capital Partners, with Nadine Vasquez serving as Managing Director on the engagement. Our understanding from transaction counsel at Harmon Ridgeway & Strauss LLP is that the sale process generated indications of interest from several potential acquirers. Cascade's all-cash offer at $26.85 per share — representing a 20.4% premium to Pinnacle's unaffected stock price — was ultimately determined by Pinnacle's board of directors to be the highest and most certain bid.
The Merger Agreement includes a company termination fee of $164.5 million (3.5% of deal value) applicable if Pinnacle terminates the agreement to accept a superior proposal. The existence of this "fiduciary out" provision — standard in public company mergers — indicates that the parties contemplated the possibility that an alternative acquirer might emerge and structured the agreement to permit Pinnacle's board to accept a superior offer if one materialized, subject to the payment of the termination fee.
However, to satisfy the third prong of the failing-firm defense, Cascade would need to demonstrate more than that it was the highest bidder. It would need to show that no less anticompetitive alternative purchaser was available — for example, a purchaser that does not operate in the online marketplace space and whose acquisition of Pinnacle would therefore not raise the same horizontal overlap concerns. The record may not support this showing. If the sale process attracted interest from financial buyers (private equity firms) or strategic acquirers outside the marketplace sector, and if those parties declined to bid at levels comparable to Cascade's offer, the analysis becomes more favorable. But if such parties were never seriously solicited, or if they were never given a meaningful opportunity to submit proposals, the prong is unlikely to be met.
One potential argument is that any alternative purchaser with meaningful marketplace or e-commerce operations would present substantially similar antitrust concerns, and that a pure financial buyer was not willing to pay a premium comparable to Cascade's offer. This argument has some surface appeal — financial buyers typically cannot match the synergy-driven valuations offered by strategic acquirers — but it requires further factual development. We would need to review the sale process materials prepared by Ridgeline Capital Partners and interview relevant participants to determine the identity and nature of the parties contacted, the bids (if any) received, and the reasons those bids were rejected or not pursued.
Conclusion on Prong 3: The evidence is mixed and probably insufficient to meet the defendants' burden. While the sale process generated some competitive interest, the record does not clearly establish that no less anticompetitive alternative was available. Further factual development is warranted, but this prong should not be relied upon as a basis for asserting the failing-firm defense at the PI hearing.
D. Overall Conclusion on the Failing-Firm Defense
The traditional failing-firm defense is not viable for Pinnacle under the current facts. Pinnacle is not facing imminent business failure, has not exhausted reorganization alternatives, and the record does not clearly establish the absence of a less anticompetitive alternative purchaser. All three prongs of the defense — as articulated in Citizen Publishing and consistently applied by the courts — remain unsatisfied.
We recommend that the failing-firm defense be preserved in our answer and pleadings. It has already been asserted as an affirmative defense in Cascade's answer to the FTC's complaint, and withdrawing it could be construed as a concession. However, we should not feature it prominently at the PI hearing and should not devote significant space to it in the Memorandum in Opposition to the FTC's motion for preliminary injunction.
There are two significant risks associated with leading with the failing-firm defense at the PI hearing. First, if the court rejects the argument — as it almost certainly would on the current record — the rejection may undermine our credibility on other, more viable defense theories. Judges are sensitive to overreaching, and presenting an argument that the evidence cannot support invites the court to view the rest of our defense with heightened skepticism. Second, the failing-firm defense is in some tension with Cascade's stated procompetitive rationale for the merger. Cascade's narrative — articulated in public filings, press releases, and the testimony we intend to present — is that the acquisition will create a stronger, more innovative marketplace platform that will enhance competition with Vertex Commerce and other rivals. Characterizing Pinnacle as a "failing" firm undercuts this narrative and may confuse the court about the nature of the competitive benefits Cascade expects to achieve.
We also flag a practical coordination concern. Any characterization of Pinnacle as a "failing" firm will be sensitive for Pinnacle's management, particularly Co-Founder and CEO Rajiv Chandravar and CFO Thomas Breck. Both individuals are expected to serve as fact witnesses at the PI hearing, and both may resist testimony that paints Pinnacle in such stark terms. Founder pride, concern about employee morale, and potential liability concerns (including securities law exposure if the merger does not close and Pinnacle's stock price is affected by courtroom characterizations of the company's viability) all counsel in favor of careful coordination with Diana Whitfield at Whitfield, Greer & Tanaka regarding the scope and tenor of any failing-firm-related testimony. We recommend discussing this topic at the next weekly joint defense coordination call.
V. Analysis of the "Weakened Competitor" / "Flailing Firm" Argument
While the traditional failing-firm defense is unavailable, the evidence of Pinnacle's competitive deterioration supports a distinct and powerful argument that the merger's anticompetitive potential is materially diminished because Pinnacle's future competitive significance is substantially less than its historical market share suggests. This section analyzes the evidence supporting the weakened-competitor argument in detail.
A. Pinnacle's Decelerating Growth
The most striking feature of Pinnacle's recent competitive trajectory is the dramatic deceleration of its GMV growth. Over the past three fiscal years, Pinnacle's YoY GMV growth rate has declined precipitously:
Several features of this trajectory are particularly noteworthy. First, the deceleration is not merely a one-year anomaly but a persistent and accelerating trend spanning three consecutive fiscal years. Pinnacle's growth rate declined by ten percentage points from FY2022 to FY2023 and by an additional nine percentage points from FY2023 to FY2024. If this trend continues — and the evidence discussed in subsequent sections suggests it will — Pinnacle's growth could approach zero or turn negative within one to two years.
Second, Pinnacle's revenue growth mirrors the GMV deceleration and is constrained by a stable take rate of approximately 16%. Because Pinnacle's primary revenue stream is commissions charged as a percentage of GMV, revenue growth is mechanically linked to GMV growth. The stability of the take rate limits Pinnacle's ability to offset GMV deceleration through pricing — raising the take rate would likely accelerate seller departures, while reducing it would compress margins further.
Third, and critically, Pinnacle's growth rate must be assessed in the context of the broader market. The overall U.S. e-commerce market generated approximately $757 billion in total GMV in 2024 and has been growing at approximately 12–14% YoY. Pinnacle's 9% GMV growth in FY2024 thus falls materially below the industry average. This means that Pinnacle is not merely growing more slowly — it is losing market share on an organic basis. Every quarter that Pinnacle grows below the market rate, its relative competitive position erodes further.
The competitive implications of this deceleration are particularly significant in the context of the FTC's proposed relevant market. The FTC alleges that Pinnacle holds a 30.1% share of "online marketplace platform services for third-party sellers in the United States." But if Pinnacle's growth rate has fallen below the industry average and continues to decelerate, that 30.1% share represents a snapshot of Pinnacle's historical position — not a reliable predictor of its future competitive significance. Just as the Supreme Court recognized in Severin Holdings that a coal company's depleted reserves made its historical production-based market share a misleading indicator of its future ability to compete, Pinnacle's decelerating growth makes its current market share a misleading indicator of its future competitive importance.
The competitive pressures driving Pinnacle's deceleration are both structural and firm-specific. On the structural side, the U.S. marketplace sector is maturing, and the intense growth that characterized the post-pandemic period (2020–2022) has given way to a more competitive environment in which established platforms compete vigorously for seller and buyer participation. On the firm-specific side, Pinnacle faces increasingly effective competition from Vertex Commerce Inc. (which holds a 35.7% share and continues to grow robustly), Nomad Shops LLC (14.6% share, with a strong brand identity among artisan and small-business sellers that directly competes with Pinnacle's core demographic), and new entrants including Brevity Social Commerce Inc. (launched 2023) and Trove Marketplace Inc. (launched 2024). We discuss these competitive dynamics in greater detail in Section V.C below.
B. Escalating Seller Churn
If decelerating GMV growth is the most visible symptom of Pinnacle's competitive weakening, escalating seller churn is the most ominous. Seller churn — the rate at which active sellers depart or become inactive on the platform over a given period — is a critical leading indicator of platform health in a two-sided marketplace, and Pinnacle's churn data reveals a deeply concerning trend.
A 21% annual seller churn rate means that Pinnacle is losing approximately one in every five active sellers each year. At 185,000 active sellers, this translates to approximately 38,850 sellers who departed or became inactive on the platform during FY2024. That Pinnacle's total active seller count has nonetheless continued to increase slightly — from approximately 175,000 in FY2022 to approximately 185,000 in FY2024 — indicates that the company has been acquiring new sellers at a rate sufficient to offset departures. But this replacement dynamic is unsustainable: the cost of acquiring new sellers is rising (as the most attractive sellers have already been solicited by competing platforms), and the quality of replacement sellers may be lower than that of departing sellers.
The sources of seller churn are varied but point consistently to the intensifying competitive pressure Pinnacle faces:
• Migration to Vertex Commerce. Vertex's 35.7% market share and extensive buyer base make it an attractive alternative for high-volume sellers seeking maximum transaction volume and exposure. Vertex has invested heavily in logistics infrastructure and AI-driven seller tools that reduce seller costs and improve the selling experience. Sellers who previously maintained a presence on both Vertex and Pinnacle are increasingly concentrating their activity on Vertex and reducing or eliminating their Pinnacle presence.
• Migration to Nomad Shops. Nomad Shops has cultivated a strong brand identity among artisan, handmade, and small-business sellers — the very demographic that formed the core of Pinnacle's original value proposition. Nomad's seller-centric tools, lower take rates for qualifying sellers, and marketing focused on the artisan community have attracted sellers away from Pinnacle in the home goods, artisanal products, and specialty foods categories that Pinnacle historically dominated.
• Direct-to-Consumer Channels. An increasing number of sellers are investing in their own direct-to-consumer e-commerce capabilities, using tools provided by companies such as Dunmore Services Inc. and Granite Harbor Services Inc. to establish independent online storefronts. This trend reduces sellers' dependence on marketplace platforms generally and diminishes the pool of sellers available to Pinnacle.
• Social Commerce. The emergence of social commerce platforms — most notably Brevity Social Commerce Inc. (launched 2023 in Los Angeles) — represents a new competitive paradigm in which commerce is integrated directly into social media environments. Sellers, particularly in fashion and lifestyle categories, are finding that social commerce platforms offer superior buyer engagement and lower customer acquisition costs. Pinnacle has been slow to adapt to this trend, and sellers are shifting activity accordingly.
The multi-homing dynamic further compounds the significance of the churn data. Many online sellers list their products on multiple marketplace platforms simultaneously, allocating their time, inventory, and marketing spend across platforms based on relative returns. In a multi-homing environment, churn does not necessarily mean that a seller exits e-commerce entirely; more commonly, it means the seller drops one or more platforms while retaining others. The acceleration of Pinnacle's churn rate suggests that sellers who previously maintained a Pinnacle presence as part of a multi-platform strategy are now choosing to drop Pinnacle — indicating that Pinnacle is increasingly the marginal platform in sellers' multi-homing calculus.
The impact of seller churn on Pinnacle's competitive position is amplified by the cross-side network effects inherent in a two-sided marketplace. When sellers depart Pinnacle, the platform's product selection narrows. A narrower product selection reduces consumer utility, which in turn reduces consumer traffic to the platform. Reduced consumer traffic diminishes the returns to remaining sellers, who then face an incentive to redirect their own activity to more heavily trafficked platforms. This creates a negative feedback loop — a vicious cycle that can be extremely difficult to arrest once it reaches a critical threshold. While we do not assert that Pinnacle has yet entered a terminal "death spiral," the trajectory of the data suggests that the company may be approaching a tipping point beyond which the feedback dynamic becomes self-reinforcing.
We have requested that Brindoval Analytics LLC — specifically Dr. Priya Ramanathan and Dr. Lucas Engström — obtain access to Pinnacle's internal seller-level data to model churn drivers in greater detail and to quantify the expected trajectory of seller departures absent the merger. This data will be critical for Dr. Ramanathan's expert report (due August 18, 2025) and for the testimony we intend to present at the PI hearing. We are coordinating with Kenneth Oshiro at Whitfield, Greer & Tanaka on data access under the Joint Defense and Common Interest Agreement executed July 1, 2025.
C. Competitive Pressures and Market Entry
Pinnacle's deceleration and seller churn must be understood in the context of the broader competitive landscape, which has evolved significantly since Pinnacle's founding in 2014 and its IPO in 2020. The market for online marketplace platform services is increasingly crowded, and Pinnacle faces competitive threats from multiple directions.
Vertex Commerce Inc. (San Jose, CA). Vertex is the largest platform in the FTC's alleged relevant market, holding a 35.7% market share by GMV. The company is well-capitalized, publicly traded, and has invested aggressively in logistics infrastructure (including a network of fulfillment centers), artificial intelligence-driven seller tools, and consumer-facing features that enhance the shopping experience. Vertex's scale advantages are significant: its large buyer base attracts sellers, and its extensive seller base attracts buyers, creating the kind of virtuous network-effects cycle that Pinnacle has struggled to maintain. Vertex is gaining market share from Pinnacle, particularly among high-volume sellers who prioritize reach and transaction volume.
Nomad Shops LLC (Brooklyn, NY). Nomad holds a 14.6% market share and has established itself as the platform of choice for artisan, handmade, and small-business sellers. Nomad's brand resonates with consumers who value authenticity, craftsmanship, and the "shop small" ethos. Critically, Nomad's target seller demographic overlaps substantially with Pinnacle's core seller base. Pinnacle's early advantage in categories like artisanal products, specialty foods, and handmade home goods — the categories on which the company built its reputation and differentiated itself from Vertex — is being eroded by Nomad's focused competitive strategy. As Nomad continues to invest in seller tools, marketing, and category expansion, Pinnacle's historical competitive moat in these categories grows narrower.
Brevity Social Commerce Inc. (Los Angeles, CA). Brevity launched in 2023 and represents a new competitive paradigm in online commerce. The platform integrates commerce directly into social media environments, leveraging influencer partnerships, user-generated content, and social graph data to drive discovery and purchases. Brevity's model is particularly appealing to younger consumers (Gen Z and younger Millennial demographics) and to sellers in fashion, beauty, and lifestyle categories. Pinnacle has been slow to adopt social commerce features and has lost ground among sellers who find Brevity's model more effective at driving engagement and sales. While Brevity's current market share is small (it falls within the "all others" category at 11.4% combined), its growth trajectory and disruptive potential merit close attention.
Trove Marketplace Inc. (Chicago, IL). Trove launched in 2024 and has differentiated itself through a technology-first approach, offering lower take rates to sellers and a streamlined onboarding process. Trove's competitive strategy is explicitly designed to attract sellers from established platforms by reducing the commission burden that sellers face. While Trove is in its early stages and its long-term viability is uncertain, its entry is indicative of the dynamism and contestability of the marketplace sector.
These competitive developments are relevant to the weakened-competitor analysis in two ways. First, they explain why Pinnacle's competitive position is deteriorating. Pinnacle is not weakening in a vacuum; it is weakening because it faces increasingly effective competition from established rivals (Vertex, Nomad) and innovative new entrants (Brevity, Trove). Second, they demonstrate that the market is dynamic and contestable — a point that reinforces the ease-of-entry defense and suggests that competitive conditions will continue to evolve regardless of whether the Cascade-Pinnacle merger proceeds.
It is also worth noting that the FTC's own complaint acknowledges Vertex Commerce's 35.7% market share — larger than Pinnacle's 30.1% and substantially larger than the combined Cascade-Pinnacle share of 38.3%. Under the FTC's own market definition, Vertex would remain the largest platform post-merger and would continue to provide a strong competitive constraint on the combined entity. This fact, combined with the evidence of Pinnacle's weakening, significantly diminishes the merger's competitive significance.
D. Financial and Operational Indicators of Weakening
Beyond the top-line GMV and seller churn metrics, additional financial and operational indicators point to Pinnacle's diminishing competitive vitality.
Margin Compression. Pinnacle's operating margins have compressed over the past several fiscal years. While we do not yet have access to the granular financial data necessary to quantify the margin decline with precision — a request for this data is pending with Pinnacle's counsel — the general trend is apparent from Pinnacle's public SEC filings and investor presentations. Margin compression reflects a combination of factors: rising seller acquisition costs (as Pinnacle must spend more to replace churning sellers), increasing investment in logistics and technology (necessary to maintain competitive parity with Vertex), and the inability to raise the take rate without accelerating seller departures. As margins compress, Pinnacle's ability to fund innovation and competitive investment is diminished, creating a further drag on the company's competitive trajectory.
Stock Price Decline. Pinnacle's stock price has declined significantly from its post-IPO highs. The company completed its IPO on September 18, 2020, at a time of significant investor enthusiasm for e-commerce platforms (buoyed in part by the COVID-19 pandemic's acceleration of online shopping trends). By March 7, 2025 — the last trading day before the merger was leaked to the market — Pinnacle's stock had declined to $22.30 per share. While stock price movements reflect a multitude of factors (including macroeconomic conditions, interest rate changes, and sector-wide valuation compression), the sustained decline in Pinnacle's stock price is consistent with the broader evidence of the company's weakening competitive position and reflects market skepticism about Pinnacle's standalone trajectory.
R&D Investment. Pinnacle's R&D spending as a percentage of revenue may be declining or stagnant, limiting the company's ability to innovate and maintain competitive parity with rivals who are investing more aggressively in platform technology, AI capabilities, and seller tools. We are working to confirm this hypothesis with data from Pinnacle's audited financial statements (audited by Kessler Fong Accounting Group LLP of Dallas, Texas) and internal financial reports. If confirmed, this trend would provide additional support for the argument that Pinnacle's competitive capabilities are diminishing.
Key Talent Departures. We have received anecdotal reports of departures by key personnel from Pinnacle's engineering and product development teams. In the technology sector, talent departures — particularly of senior engineers, product managers, and data scientists — can be both a symptom and a cause of competitive decline. Talented employees are attracted to companies with strong growth trajectories and innovative cultures; when a company's competitive position deteriorates, its most talented employees are often the first to leave, depriving the company of the human capital necessary to reverse the decline. We are working to confirm these reports through diligence and coordination with Whitfield, Greer & Tanaka.
Potential Testimony of Thomas Breck. Thomas Breck, Pinnacle's CFO, may be an effective witness on these financial and operational indicators at the PI hearing. Breck can speak credibly to the company's financial trajectory, the competitive pressures it faces, and the challenges of sustaining growth and investment in an increasingly competitive marketplace environment. His testimony can contextualize the quantitative data — the GMV deceleration, the margin compression, the churn metrics — within a narrative of competitive weakening, without requiring him to characterize Pinnacle as a "failing" firm. This is an important distinction: the weakened-competitor argument does not require any Pinnacle witness to testify that the company is failing or on the verge of collapse. It requires only that the evidence show Pinnacle's competitive significance is declining — a characterization that Breck should be willing to support.
E. Application of the *Severin Holdings* and *Arch Coal* Frameworks
The evidence of Pinnacle's competitive deterioration maps directly onto the analytical frameworks established by the Supreme Court in Severin Holdings and applied by the D.C. district court in Arch Coal.
Under Severin Holdings, the relevant inquiry is whether market share data accurately reflects a firm's "future ability to compete." The Supreme Court held that where a firm's competitive resources are depleted or declining, historical market shares overstate the anticompetitive effect of a merger involving that firm. The Court emphasized that Section 7 of the Clayton Act is concerned with the probable future effects of a merger on competition, not merely with the mathematical rearrangement of historical market share figures. Where the evidence demonstrates that a firm's competitive position is eroding — for reasons independent of the merger — the market share statistics on which the government relies lose much of their probative force.
Under Arch Coal, the D.C. district court applied the Severin Holdings framework in denying the FTC's motion for preliminary injunction against a coal industry merger. The court credited the defendants' evidence that the target firm's competitive significance was declining — that its reserves, contracts, and market position were deteriorating — and concluded that the FTC had not established a likelihood of success on the merits. Critically, the court reached this conclusion without requiring the defendants to satisfy the strict three-pronged failing-firm defense. The weakened-competitor analysis operated independently as a basis for rebutting the FTC's prima facie case.
Applied to Pinnacle, these frameworks support the following argument:
Pinnacle's 30.1% market share — the figure on which the FTC's concentration analysis and competitive effects theory depend — overstates Pinnacle's future competitive significance because:
1. Growth is decelerating and has fallen below the industry average. Pinnacle's GMV growth declined from 28% YoY in FY2022 to 9% YoY in FY2024, while the broader U.S. e-commerce market grew at 12–14% YoY. This means Pinnacle is losing market share on an organic basis and is likely to continue doing so.
2. Seller churn is accelerating, eroding the two-sided network effects that sustain platform competitiveness. Pinnacle's seller churn rate nearly doubled from 12% in FY2022 to 21% in FY2024, indicating that sellers are increasingly choosing to leave the platform in favor of competitors. In a two-sided marketplace, seller departures reduce product selection, which reduces buyer traffic, which further reduces seller returns — a negative feedback dynamic that accelerates competitive erosion.
3. Competitors and new entrants are gaining ground. Vertex Commerce (35.7% share) continues to grow robustly, Nomad Shops (14.6% share) is directly eroding Pinnacle's position in its core artisan and specialty categories, and new entrants like Brevity Social Commerce and Trove Marketplace are introducing innovative competitive models that Pinnacle has been slow to adopt.
4. The trajectory is clear and is likely to continue. The data suggest that Pinnacle's market share will continue to erode absent the merger. The deceleration in growth and the acceleration in churn are not one-time events but persistent, multi-year trends driven by structural competitive forces.
The implication for the FTC's case is profound. Even if the FTC's narrow market definition ("online marketplace platform services for third-party sellers in the United States") is accepted for purposes of analysis, the merger's competitive impact is substantially overstated. One of the merging parties — the larger of the two, in fact — is a weakening player whose market share would decline regardless of the transaction. The concentration statistics on which the FTC relies (post-merger HHI of 2,856, delta of 495) are premised on the assumption that Pinnacle will maintain its current 30.1% market share. If that share is projected to decline significantly — as the evidence strongly suggests — the forward-looking HHI delta would be materially smaller, and the merger would fall closer to or below the presumption thresholds in the Merger Guidelines.
This argument dovetails with — and reinforces — the broader market definition argument presented in the Market Definition Analysis Memorandum (dated July 10, 2025). If the relevant market is properly defined as "all e-commerce retail" rather than the FTC's artificially narrow "online marketplace platform services" market, the combined Cascade-Pinnacle share is approximately 7.3% of total U.S. e-commerce GMV of $757 billion. At that level of concentration, the weakened-competitor evidence becomes almost superfluous — the merger would not raise competitive concerns under any plausible analytical framework. But even under the FTC's narrow market definition, the weakened-competitor evidence provides a strong independent basis for challenging the Commission's prima facie case.
F. Counterarguments and Risks
Any credible analysis of a defense theory must confront the strongest counterarguments the opposing party is likely to advance. We identify the following anticipated FTC responses and associated risks.
FTC Response: Pinnacle Is Not Failing and Remains a Significant Competitive Force. The FTC will argue that Pinnacle, with $11.4 billion in GMV, $1.82 billion in net revenue, and 185,000 active sellers, is far from a weakened competitor. The Commission will emphasize that deceleration is not decline and that Pinnacle remains one of the two largest platforms in the alleged relevant market. The FTC will note that Pinnacle continues to acquire new sellers (its total active seller count increased from approximately 175,000 to approximately 185,000 over the 2022–2024 period), continues to grow (albeit at a slower rate), and continues to generate positive revenue and earnings.
This argument is the strongest the FTC will advance on this point, and we must be careful not to overstate the weakened-competitor narrative. Our argument is not that Pinnacle is irrelevant or that it has already ceased to be a competitive force. Our argument is more nuanced: that Pinnacle's historical market sha
