Exelon

2000

Biggest isn’t safest — Exelon’s scale came from mergers, not reliability.

Exelon is a textbook example of regulatory scale without operational rigour: it grew to dominate U.S. regulated electricity delivery through mergers, then faced repeated enforcement actions for environmental and nuclear safety failures.

    The merger that defined scale

    The 2016 Pepco merger made Exelon the largest regulated U.S. utility by customers and revenue.

  2. 2:33
    The spin-off that redefined scope

    In 2022, Exelon spun off its generation business — Constellation Energy — separating regulated delivery from unregulated power production.

  3. 4:24
    Penalties for routine failures

    Exelon paid fines for sulfur dioxide over-emissions in 2005 and for permitting sleeping security guards at Peach Bottom in 2009.

  4. 5:56
    Delayed disclosure, not isolated incident

    Exelon withheld disclosure for four years — until 2006 — of tritium spills from Braidwood Nuclear Generating Station occurring over a decade.

The written brief1 min read

What the company or idea is

Exelon is an American public utility formed in 2000 by merger, headquartered in Chicago, operating six regulated electric utilities.

How it actually makes money

Exelon makes money by charging regulated rates for electricity delivery through six state-regulated utilities across multiple states.

What works

The 2016 Pepco merger delivered scale: Exelon became the largest regulated U.S. utility by customer count (10 million) and revenue.

What does not

Its nuclear operations have repeatedly failed basic safety and transparency standards: delayed tritium leak disclosures, on-duty sleeping guards, and emissions violations show systemic compliance failures.

What to take from it

Growth via acquisition — especially the 2016 Pepco merger — built market dominance without improving operational discipline or accountability.

Is it worth your time

Yes — as a case study in how scale, regulatory capture, and operational risk compound in vertically structured utilities.

MeituanWang Xing · 2010Meituan is a Chinese technology company headquartered in Beijing that operates a platform for local services, including on‑demand food delivery, in‑store services, consumer reviews under Dazhong Dianping, hotel and travel bookings, and instant retail. It monetises through fees on its platform, taking a commission on food delivery orders and charging merchants for booking and in‑store services. Meituan’s rapid user growth is driven by its extensive coverage of local services, its integration of food delivery, in‑store services, and hotel bookings creating a one‑stop shop, and its large merchant base of 14.5 million active merchants providing network effects. Meituan faces regulatory scrutiny in China, its 2021 post by Wang Xing triggered a 7.1 % share plunge and anti‑monopoly investigation, and the company has been subject to scrutiny by Beijing Municipal Human Resources and Social Security Bureau. Meituan demonstrates the power of a diversified local‑services platform, its ability to scale across cities and internationally shows the importance of network effects, and its regulatory challenges highlight the need for compliance awareness. Meituan offers a case study in rapid scaling and diversification, but its regulatory risks caution investors.
