Federal regulators are pumping the brakes on T-Mobile's proposed mega-merger with Sprint, with the FCC saying it needs more time to review newly-submitted information.

• What matters: Both companies are brushing off the slowdown, claiming that they always expected approval to drag, but they both implied that this was a regulatory slam dunk when first announcing the deal in April. That they felt compelled to produce and deliver new and deeper models suggests they know there's still some reflexive resistance to letting the nation's #3 and #4 wireless carriers merge.
• What doesn't matter: That the FCC paused the 180-day "shot clock," which is just an informal, non-binding period.
• Remember that DOJ will also have its say on this, in addition to the FCC. Axios' Kim Hart emails: "The deal will be a big test case for antitrust enforcers, particularly after the DOJ lost its case to block AT&T-Time Warner. Unlike that one, this is a horizontal deal that would remove a direct competitor from the market and could have direct price impact-- a key metric in these sorts of reviews."
• Go deeper: Sprint and T-Mobile's pitch to D.C.

• New firm alert: Steve Glickman, a former economic advisor to President Obama, has launched a new consulting firm called Develop, which will advise investors who want to participate in low-income "opportunity zones." More from Bloomberg:

The opportunity-zone breaks were one of the lesser-known provisions of the federal tax overhaul signed into law in December, but they’ve sparked a tremendous amount of interest. They’re especially attractive to firms seeking to redeploy capital gains. Investors start by plowing those proceeds into “opportunity funds,” deferring taxes until 2026. If the funds buy and hold qualifying assets for at least five years, investors can reduce the tax they pay on appreciation or eventually eliminate it altogether.

• IC-ohhhh: A federal judge in Brooklyn yesterday refused to dismiss a case brought against the founder of a cryptocurrency, who tried arguing that the tokens weren't securities.

• Cryptocurrency companies are getting their own D.C. lobbying group, as companies like Coinbase and Circle reportedly have helped create something called the Blockchain Association.

• Leaving it on the table: Cadbury is stockpiling chocolate — both ingredients and finished product — in case there is a hard Brexit, per the Times of London.

NIO, a Chinese electric car company whose backers include Baidu and Tencent, raised at least $1 billion in an IPO that priced at $6.25 per share (low end of range). The company will trade on the NYSE with an initial market cap of $6.4 billion, while Morgan Stanley was lead underwriter.

• Why it's the BFD: Because it successfully got out in an environment where shares of both automakers and Chinese tech companies are under pressure. Yes it priced low, but that's as much a reflection on the bankers as the company, and a $1 billion public float shouldn't be downplayed.
• Bottom line: NIO may someday become a rival to Tesla, but so far it makes Elon Musk's manufacturing output look prodigious. The Chinese upstart only began making deliveries this past June, with fewer than 2,000 vehicles shipped through the end of August.
