The playbook
The rationale that repeats.
Three patterns show up across NEXTERA ENERGY's deal book — what the team buys, how it pays, and how it integrates. The patterns are the throughline; the individual deals below are the evidence.
01
Acquisition criteria
Bolt-on regulated franchises around the Florida core.
NextEra's clearest completed M&A is buying rate-regulated utilities adjacent to Florida Power & Light: Florida City Gas (~$530M) and Gulf Power closed out of the ~$6.475 billion all-cash Southern Company package. Management framed these as 'attractive electric and natural-gas franchises' that complement existing Florida operations and were expected to be immediately accretive to earnings.

02
Capital deployment
Big regulated-utility merger bids that regulators blocked.
The Constellation Energy merger of equals (2005), the Hawaiian Electric acquisition (2014) and the ~$18.7 billion Oncor / Energy Future Holdings bid (2016) were all announced as transformational, and all three were abandoned — Constellation by mutual termination in 2006, Hawaiian Electric and Oncor after state utility commissions rejected them. The pattern shows NextEra repeatedly reaching for large regulated platforms but facing acute regulatory and political execution risk.

03
Integration approach
All-stock structures for scale, cash for tuck-ins.
The largest combinations — Constellation, Hawaiian Electric and the 2026 Dominion Energy deal — were structured as stock-for-stock exchanges keyed to fixed ratios (1.444x, 0.2413x and 0.8138x respectively), preserving balance-sheet capacity, while the franchise tuck-ins (Florida City Gas, Gulf Power) were all-cash. Across the deals management consistently cited scale-driven capital, operating and financing efficiencies as the rationale.

NextEra agreed to combine with Dominion Energy, the Virginia-based regulated utility serving customers in Virginia, North Carolina and South Carolina, in a two-step merger (Merger Sub Corp into Dominion, then the survivor into LLC Sub). The companies described the combination as creating the world's largest regulated electric utility business by market capitalization, with a combined rate base of about $138 billion expected to grow ~11% through 2032 and operations more than 80% regulated.
Why it was attractive
01Adds a large
02growing regulated rate base in four of the fastest-growing U.S. states and an offshore-wind platform
03lifting combined operations to more than 80% regulated
Capabilities acquired

This is a historic moment for our two companies and for the states we are privileged to serve. Electricity demand is rising faster than it has in decades. Projects are getting larger and more complex. Customers need affordable and reliable power now, not years from now. We are bringing NextEra Energy and Dominion Energy together because scale matters more than ever — not for the sake of size, but because scale translates into capital and operating efficiencies.
John KetchumChairman, President and CEO, NextEra Energy
The Dominion Energy name isn't changing, nor is how we operate locally, serve our customers or engage with the community. The same leaders and the same teams customers know and trust will continue serving Virginia, North Carolina and South Carolina.

NextEra completed the acquisition of the outstanding common shares of the entity that owns Florida City Gas under a stock purchase agreement with NUI Corporation and Southern Company Gas, affiliates of The Southern Company, for approximately $530 million in cash.

On July 29, 2018, NextEra Energy, Inc. completed the previously announced acquisition of the outstanding common shares of the entity that owns Florida City Gas (FCG) under a stock purchase agreement with NUI Corporation and Southern Company Gas, affiliates of The Southern Company, for approximately $530 million in cash.
NextEra EnergyForm 8-K (Item 2.01), filed July 30, 2018
NextEra agreed to acquire 100% of the equity of reorganized Energy Future Holdings (EFH) and Energy Future Intermediate Holding Company (EFIH) — the indirect owner of about 80.03% of Oncor Electric Delivery Company, the largest regulated electric distribution and transmission system in Texas — as part of EFH's Chapter 11 plan of reorganization. NextEra later raised its commitment to acquire additional minority Oncor interests (see Texas Transmission Holdings). The deal was ultimately rejected by the Public Utility Commission of Texas in 2017 and abandoned.
Why it was attractive
01Oncor is the largest regulated electric T&D system in Texas — a large
02stable
03rate-regulated asset base
04acquiring it out of bankruptcy offered a path to certainty of value for creditors
Capabilities acquired
regulated electric transmission and distribution across Texas (Oncor)
We are pleased by today's bankruptcy court ruling and view it as an important next step in the process to acquire Oncor.
Jim RoboChairman and CEO, NextEra Energy
Alongside the Oncor/EFH transaction, NextEra and its wholly owned subsidiary WSS Acquisition Company (TTHC Merger Sub) entered into an agreement with Texas Transmission Holdings Corporation (TTHC) and certain TTHC stockholders (Cheyne Walk Investment Pte Ltd, Borealis Power Holdings Inc. and others) to acquire the remaining minority ownership interest in Oncor that NextEra would not obtain through the EFH transaction. It was abandoned when the broader Oncor acquisition was rejected by Texas regulators.
Why it was attractive
01Would have given NextEra full ownership of Oncor rather than the ~80% available via EFH
Capabilities acquired
minority equity interest in Oncor Electric Delivery Company
NextEra entered into an Agreement and Plan of Merger with Hawaiian Electric Industries (HEI), the parent of Hawaii's largest electric utilities serving Oahu, Maui and Hawaii Island. Before the merger, HEI would distribute its American Savings Bank subsidiary to HEI shareholders (the Bank Spin-Off); in the merger each HEI share would convert into 0.2413 NEE shares. The deal was rejected by the Hawaii Public Utilities Commission in 2016 and terminated.
Why it was attractive
01HEI's regulated Hawaiian electric utilities offered an isolated
02high-renewable-penetration grid where NextEra's renewable and operating expertise was positioned as a fit
Capabilities acquired
regulated electric utility operations across the Hawaiian islands
FPL Group (NextEra's predecessor) entered into an agreement and plan of merger with Constellation Energy Group and Constellation's subsidiary CF Merger Corporation to create what the companies described as the nation's largest competitive energy supplier and second-largest electric utility portfolio, a combined company with about $28 billion market capitalization, $27 billion in annual revenues and $57 billion in total assets, to be named Constellation Energy. FPL Group and Constellation terminated the merger in October 2006.
Why it was attractive
01Constellation paired a regulated utility (BGE) with one of the largest competitive/merchant energy businesses
02complementing FPL Group's regulated Florida utility and growing merchant fleet
Capabilities acquired
regulated electric utilities (Florida Power & LightBaltimore Gas and Electric) plus competitive/merchant generation and energy marketing
It brings together two strong, successful industry leaders with extensive and complementary assets and skill sets, combining the best of the regulated utility and competitive energy sectors.
