Tilson Technology Management has filed for Chapter 11 bankruptcy.

In an announcement last week, Tilson, a developer of fiber and wireless networks, said it has made the bankruptcy filing following the abrupt cancellation of one of its client’s contracts.

Tilson's financial troubles began earlier this year when Gigapower - the company’s largest client, formed out of a joint venture between telecommunications giant AT&T Inc. and BlackRock - terminated nearly all of its construction projects with Tilson, including all construction in Arizona, plus nearly all of the remaining construction work in Las Vegas.

As reported by Wireless Estimator, Tilson had invoiced roughly $20 million in change orders that went unpaid. This caused Gigapower to “terminate for convenience” on April 29, 2025.

Founded in 1996, Maine-based Tilson has more than 1,000 employees and serves both the public and private sectors.

In the announcement last week, Tilson said the Chapter 11 in the US Bankruptcy Court for the District of Delaware gives the company its best chance for long-term success.

The company said that it has received a commitment for $37.5 million in debtor-in-possession financing from its existing lenders to support operations throughout the Chapter 11 process.

Tilson said it aims to complete the restructuring "as quickly as possible," and expects to emerge from Chapter 11 as a "financially stronger company in the third or fourth quarter of 2025."

"Our core business is strong, but we need to reset after one client’s failure to manage its relationships with its host communities and pay us for the work we performed materially changed our revenue expectations,” said Darrell Ingram, CEO of Tilson.

“The steps we’re taking today represent a new beginning, not an end,” Ingram added. “We are fortunate that our lenders continue to believe in our business and support us financially, so we can overcome this setback and create a strong financial future for our company."

Following the company's filing last week, two former Tilson employees filed a class‐action adversary complaint against the company.

Plaintiffs Jeffrey Hals of Arizona and Charles Mamala Jr. of Nevada allege that Tilson, without warning, furloughed and then terminated more than 50 workers at its Chandler, Arizona, and Las Vegas, Nevada, facilities. The two state that this was done without providing the 60 day advance notice that the statute requires.
