• Lawsuit Type: Securities Class Action

Introduction

A securities class action was filed on July 23, 2026 in the United States District Court for the District of Columbia against Cogent Communications Holdings, Inc., founder, Chief Executive Officer, and Chairman David Schaeffer, and Chief Financial Officer Thaddeus G. Weed. The lawsuit is brought on behalf of investors who purchased Cogent common stock between February 29, 2024 and May 1, 2026.

The case centers on a business Cogent portrayed as the engine of its post-acquisition future: optical wavelength services built on the former Sprint wireline network acquired from T-Mobile. According to the complaint, defendants told investors that Cogent had a large and growing backlog of wavelength opportunities, that customer demand was stronger than expected, and that the company remained positioned to meet ambitious revenue and margin targets while continuing its long-running dividend policy.

As the complaint alleges that these issues and related risks were revealed or materialized through later disclosures and market events, including earnings releases, credit-rating actions, the forced sale of pledged shares, and the dividend cut, CCOI shares fell from a Class Period high of more than $86 to less than $17.

Backdrop and Business Context

Cogent Communications was founded in August 1999 in Washington, D.C. by David Schaeffer. Its founding premise was blunt: treat bandwidth like a commodity, build or acquire high-capacity network assets, and sell internet connectivity at scale. The company grew out of the post-dot-com telecom wreckage by buying distressed fiber and ISP assets, including PSINet and Allied Riser, and eventually became a public company trading under CCOI. A later transformative event came in May 2023, when Cogent acquired T-Mobile's former Sprint wireline business for $1, adding long-haul fiber, technical sites, customer relationships, and a new strategic push into optical wavelength services.

Cogent is a facilities-based Tier 1 internet service provider that sells recurring connectivity services to businesses, carriers, content providers, and bandwidth-intensive customers. Its core offerings include dedicated internet access, IP transit, private network services, optical wavelength and transport, Ethernet transport, IPv4 address leasing, and colocation. The company serves corporate customers in office buildings, net-centric customers such as carriers and content platforms, and enterprise accounts that often require multi-site connectivity. Web research indicates Cogent reported approximately $975.8 million in full-year 2025 service revenue and employed roughly 1,900 people in recent filings.

The wavelength opportunity placed Cogent into a highly competitive long-haul transport market against long-established network operators with established customer bases and wavelength-service capabilities. The Sprint wireline acquisition gave Cogent a broader North American footprint, but it also brought integration work, data center enablement, provisioning demands, debt, and customer-conversion risk. According to the complaint, that dependency became central to the alleged fraud: Cogent's turnaround thesis required wavelength demand to translate into paying customers, yet defendants allegedly overstated the quality and convertibility of the backlog.

Promises Made vs. Reality

Throughout the class period, Cogent presented its optical wavelength business as the growth lever that would make the Sprint wireline acquisition work. On February 29, 2024, Schaeffer told investors that Cogent had generated $3.3 million of wavelength revenue in the prior quarter, had 667 installed wavelengths, and had a sales and provisioning funnel of more than 2,300 orders. He emphasized that the backlog had "more than doubled sequentially" and said the company expected continued acceleration in order value based on conversations with customers and information from its sales force.

The message continued in May 2024. Schaeffer acknowledged longer provisioning cycles but characterized the repurposing of the network as progressing well and described "a significant backlog and funnel of over 2,400 wavelength opportunities." He also claimed demand for the relevant routes and data centers was "stronger than we had initially expected," while reiterating confidence that the wavelength business could reach a $500 million run rate by May 2028. The complaint alleges this framing reassured investors that Cogent's newly acquired assets were attracting real customer demand, even though many purported orders allegedly were not likely to become paid installations.

By August and November 2024, the numbers grew larger. Schaeffer stated that wavelength revenue would "materially accelerate starting in early 2025" after network integration and optimization, and he reported a backlog and funnel of more than 2,700 unique wavelengths. In November 2024, he increased the stated backlog to more than 3,400 wavelength opportunities. Although he cautioned that Cogent was "not sure all of these orders will, in fact, be installed," the complaint alleges defendants failed to disclose that the vast majority of the backlog was vulnerable to falling out and that customer readiness was far weaker than the company's public narrative suggested.

The dividend story ran alongside the wavelength story. Cogent's 2023 annual report and subsequent quarterly filings, signed by the Individual Defendants, stated that based on current circumstances the company planned to continue its dividend policy. The filings also asserted that cash on hand, operating cash flow, and cash from the IP Transit Services Agreement with T-Mobile would be adequate to meet working capital, capital expenditures, debt service, dividend payments, and other cash requirements if Cogent executed its business plan. The complaint alleges those statements were misleading because Cogent lacked the business fundamentals and financial capacity to maintain its long-standing dividend policy if the wavelength ramp failed.

The disclosures came in stages. In February 2025, Cogent revealed that its backlog had declined from 3,400 to 2,700 after management removed 1,500 stale orders, and wavelength connection growth slowed sharply. In May 2025, Schaeffer admitted that 90% of the previously cited 3Q24 backlog had "fell out" and that this result was "as expected." In August 2025, Cogent reported weak wavelength installs, rising leverage, and several hundred provisioned wavelengths that were not being billed because customers were not accepting service. In November 2025, Cogent cut its quarterly dividend from $1.015 to $0.02, ending a 52-quarter streak of dividend increases. Later disclosures in February and May 2026 further undermined the backlog narrative, including Cogent's decision to stop reporting specific backlog numbers and Schaeffer's acknowledgement that customers were pushing out acceptance of wavelengths.

As alleged in the complaint, defendants' public statements created an impression of durable wavelength demand, credible backlog conversion, attainable long-term targets, and dividend sustainability, while concealing that the backlog was largely unlikely to become paying business, that many customers were unable or unwilling to accept delivery, that Cogent was not on track to achieve its revenue and margin targets, and that Schaeffer's pledged shares created an undisclosed risk of forced sales if Cogent's stock price fell.

Investor Harm and Market Reaction

The first alleged corrective disclosure came on February 27, 2025, when Cogent revealed that the wavelength backlog had fallen from 3,400 to 2,700 after management removed 1,500 stale orders. Investors also saw that wavelength customer connection growth had slowed from 287 net additions in 3Q24 to 77 net additions in 4Q24. CCOI fell $7.65 per share, or 10%, that day on abnormally high volume.

The pressure intensified on May 8, 2025, when Cogent disclosed only $7.1 million in wavelength revenue and made additional admissions about backlog conversion. The complaint highlights Schaeffer's acknowledgement that 90% of the previously cited 3Q24 backlog had fallen out. CCOI declined $3.91 per share, or 7%, on abnormally high volume.

The August 2025 disclosures brought a sharper reaction. Cogent added only 147 net wavelength connections in 2Q25, reported higher leverage, and told investors that several hundred wavelengths had been provisioned but were not being billed because customers had not accepted service. CCOI fell $8.54 per share, or 19%, on August 7, 2025 and another $4.72 per share, or 13%, on August 8, 2025. The complaint alleges the harm was magnified when lenders seized and sold 2.66 million pledged shares of Schaeffer's Cogent stock for $82.5 million.

The largest later decline followed Cogent's November 2025 announcement that it had cut its quarterly dividend by 98% and paused stock buybacks. From November 5, 2025 to November 13, 2025, CCOI fell from $38.30 to $16.68, a $21.62 per-share decline, or 56%. Additional declines followed the February 2026 and May 2026 disclosures, with the stock ultimately closing at $16.37 on May 4, 2026, more than 80% below the Class Period high of more than $86 per share.

Litigation & Procedural Posture

The complaint asserts claims under Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 against all defendants, and Section 20(a) control-person claims against all defendants based on the alleged conduct of Cogent and the Individual Defendants.

Defendants: Cogent Communications Holdings, Inc.; Founder, Chief Executive Officer, and Chairman of the Board David Schaeffer; and Chief Financial Officer Thaddeus G. Weed.

Scienter allegations center on defendants' alleged knowledge of, or reckless disregard for, the true state of Cogent's optical wavelength business, backlog conversion, customer demand, leverage, and dividend sustainability. The complaint alleges the Individual Defendants had access to internal data, customer information, provisioning status, SEC reporting controls, and core operational metrics, and that the wavelength business was central to Cogent's turnaround plan. The complaint also cites Schaeffer's pledged shares, alleged forced sales, more than $170 million of stock sales during the Class Period, statements about customer communications, and the departure of Cogent's Vice President of Global Sales and Chief Revenue Officer; no confidential witnesses are cited.

Procedurally, the case is at the complaint-filing stage and seeks certification of a class of all persons who purchased or otherwise acquired Cogent common stock during the Class Period and were damaged. Defendants are expected to respond to the complaint, and any motion to dismiss would likely test whether plaintiffs adequately plead falsity, scienter, loss causation, and damages under the Exchange Act. Lead plaintiff submissions are due September 21, 2026.
