T-Mobile and Sprint, respectively the third and fourth largest wireless carriers in the U.S., are nearing a merger agreement, undisclosed sources told Reuters Friday. A due diligence period would follow the finalization of the agreement’s terms, but the companies expect a deal by October, according to Reuters’ source.

In August, Reuters says, Sprint CEO Marcelo Claure said an announcement regarding merger talks would come in “the near future.”

The merger proposal would be the first one “with significant antitrust risk” to be submitted to the Federal Trade Commission since President Donald Trump took office, Reuters notes. The President was elected on a platform that included the deregulation of the business environment.

Mayoshi Son, the founder of Japanese venture capital firm SoftBank, which controls the Sprint Corporation, met with Trump in late December, just after the former tycoon won the election.

Son found Trump’s business policy potentially favorable for SoftBank, and promised to invest $50 billion in the U.S. economy and to create 50,000 jobs.

A merger proposal would evince Son’s confidence that the regulatory environment has become laxer since Sprint and T-Mobile abandoned a merger proposal in 2014 amidst pressure from the FTC.

Indeed, the FTC might be more receptive to a transformative merger in the telecom industry now than it was three years ago. Earlier this year, Reuters says, FTC Chairman Ajit Pai said “effective competition [exists] in the marketplace for mobile wireless services.” Thursday, the agency will vote on whether to submit Pai’s report on the state of competition in the wireless services market to the U.S. Congress, which requires such a report annually.

But, the terms of the new merger will likely be less advantageous for Son and Sprint than those reached in 2014. Under the previous deal, Sprint would have controlled the combined company, while T-Mobile’s parent company, Deutsche Telecom, would have become a minority shareholder.

Over the past three years, though, T-Mobile has outperformed Sprint. Accordingly, the terms of the new agreement will likely flip, Reuters’ source said. Deutsche Telecom and T-Mobile stockholders would own a majority of the combined enterprise, while SoftBank and the rest of Sprint’s shareholders would have a minority stake.

T-Mobile CEO John Legere, who took the reins in 2012 and has guided the company’s surge, will likely run the combined company.

The merged enterprise would have 130 million subscribers, Reuters notes, making it the United States’ third-largest wireless carrier, behind AT&T, which had 136.5 million subscribers as of July, and Verizon, which reported 147.2 million subscribers that same month.

Sprint’s market cap of approximately $34 billion, combined with T-Mobile’s $53 billion figure, would give the new company a value of around $87 billion. AT&T’s market cap is about $237 billion; Verizon’s exceeds $205 billion.

Sprint reported annual revenue of $33.3 billion for fiscal 2016, which ended March 31. T-Mobile posted $37.2 billion in annual revenue for calendar 2016. So, the combined company would likely generate over $70 billion annually.

Verizon posted consolidated revenues of $126 billion and wireless revenues of $89.2 billion in 2016. AT&T’s figure came in at $163 billion.

Analysts say the Sprint/T-Mobile merger provides ample opportunity to cut expenses as well.

In their bid for regulatory approval, the companies will likely emphasize that the combined company would create jobs by making investments in the development of 5G, the next generation of mobile internet connectivity.

But the merger will also precipitate layoffs as the new company consolidates its corporate structure, Roger Entner of Recon Analytics told Reuters.

According to Reuters, Sprint briefly pursued a merger with Charter Communications earlier this year.

The FTC continues to review another potential consolidation in the industry: AT&T’s proposed $85.4-billion acquisition of Time Warner.

Sprint shares jumped six percent Friday; T-Mobile stock rose 1.06 percent.
