NUA Strategy for Utility Company Employees (Duke Energy, NextEra, Exelon, AEP, Southern Company)

Long-tenure utility employees are natural NUA candidates. Thirty-year careers at regulated electric and gas utilities produce employer stock positions with cost basis from an era when these companies traded at a fraction of today's prices — generating federal tax savings of $50,000 to $150,000+ on a well-structured NUA election. But the sector has three complications that generalist advisors routinely miss: the Exelon/Constellation Energy spin-off trap (where the most dramatically appreciated shares — CEG, now around $250/share — are not employer securities and cannot be NUA'd), the Duke Energy/Progress Energy merger basis chain (where Progress Energy shareholders received Duke shares at an adjusted ratio and need separate basis verification), and defined benefit pension income that fills ordinary income brackets before the cost basis distribution hits — determining whether the basis lands at 12%, 22%, or 24%. The federal savings are real and often large; the analysis just requires more care than a generalist brings to a standard IRA rollover conversation.

Why utilities employees are NUA candidates

Several structural features of long-tenure utility careers produce favorable NUA conditions:

• Career-long employment with employer match in company stock. Regulated electric and gas utilities are among the most stable employers in the country. Engineers, lineworkers, plant operators, regulatory staff, and corporate employees routinely complete 25–35 year careers at a single company. Employer match contributions made in the 1990s and 2000s — when utility stocks traded at significantly lower prices — can produce 3:1 to 8:1+ appreciation ratios on the blended cost basis by the time of retirement.
• Predictable retirement timing creates a planning window. Unlike tech or financial-sector employees who may face involuntary separation, utility employees often retire on a planned schedule — frequently at age 58–63 with full pension vesting. This predictability enables multi-year NUA pre-planning: verifying cost basis, structuring the distribution year, and timing the election to minimize bracket exposure before Social Security and RMDs add to income.
• DB pensions create the bracket-stacking variable. Most major regulated utilities maintain defined benefit pension plans for long-tenure employees. Pension income is fixed, begins on day one of retirement, and fills the lower ordinary income brackets before the NUA cost basis distribution adds to them. Understanding where the cost basis distribution lands — and timing NUA relative to pension income, Social Security, and RMDs — determines whether the basis is taxed at 12%, 22%, or 24%, and whether the 0% or 15% LTCG bracket applies to post-distribution tranche selling.
• State tax landscape varies significantly. Utility companies are geographically concentrated — Duke Energy in the Carolinas, NextEra in Florida and the Midwest, Exelon in the Mid-Atlantic and Illinois, AEP in Ohio and Texas, Southern Company in Georgia and Alabama. Florida and Texas residents capture the full federal NUA advantage with no state income tax. Ohio, Virginia, Illinois, and Georgia residents get federal-only benefit, since those states tax long-term capital gains as ordinary income.

Major utilities 401(k) plans

Plan structure, recordkeeper, and employer stock options change. Verify with your current HR benefits portal or Summary Plan Description before making any distribution decisions. Confirm in writing that the plan allows in-kind distribution of employer stock to a taxable brokerage account — this is not universal.

Exelon: the Constellation Energy spin-off trap

Of all the corporate events in the regulated utility sector in recent years, the Exelon/Constellation Energy separation on February 1, 2022, creates the most consequential NUA planning complication — and the one most likely to catch a generalist advisor off guard.

What happened in the spin-off

On February 1, 2022, Exelon Corporation completed the separation of its competitive nuclear generation and energy marketing business into a new, standalone public company: Constellation Energy Corporation (NASDAQ: CEG). Exelon distributed one share of CEG for every three shares of EXC held as of the record date — a distribution ratio of 0.333333 CEG shares per EXC share. The distribution was structured as a tax-free spin-off for U.S. federal income tax purposes under IRC §355.¹

After the separation, Exelon retained the regulated utility businesses (ComEd in Illinois, PECO in Pennsylvania, BGE in Maryland, Pepco in D.C./Maryland, Delmarva Power, and Atlantic City Electric). Constellation became an independent nuclear and power generation company focused on carbon-free electricity — a separate entity from Exelon for all purposes, including corporate identity.

The NUA eligibility question for Exelon employees

As a result of the spin-off, Exelon employees who held EXC shares in their 401(k) on the record date now hold both EXC and CEG shares inside their plan. The NUA eligibility test under IRC §402(e)(4) requires that the stock distributed in-kind must be "employer securities" — stock of the employer or a member of the same controlled group. Exelon employees' employer is Exelon Corporation. Constellation Energy Corporation is a completely separate, independent company after the spin-off.

Practical result:

• EXC shares in the 401(k): Employer securities for Exelon employees. Eligible for NUA election. ✓
• CEG shares in the 401(k): NOT employer securities for Exelon employees. Cannot be NUA'd. Must be rolled to an IRA or treated as a regular distribution. ✗

Basis allocation between EXC and CEG

Because the Exelon spin-off was tax-free, the original EXC cost basis must be allocated between the continuing EXC shares and the new CEG shares received, based on relative fair market values on the distribution date. The IRS allocation method (per Treas. Reg. §1.358-2) uses FMVs of each company's shares on the distribution date.

At the February 1, 2022 distribution, approximate opening prices were:

• Post-spin EXC: approximately $41–$44/share (3 shares per original lot)
• CEG received: approximately $20/share (1 share per 3 original EXC shares)

For every 3 original EXC shares with blended basis of, say, $150 (i.e., $50/share average pre-spin):

• Value of 3 continuing EXC shares at ~$42: $126 → 86.3% of total value → EXC basis allocation: $129.45 ($43.15/share)
• Value of 1 CEG share at $20: $20 → 13.7% of total value → CEG basis allocation: $20.55/share

The result: post-spin EXC shares may have a basis close to or above their current market price (~$46.60), producing a very modest or zero NUA opportunity on EXC alone. The CEG shares have a low allocated basis (~$20/share) but a 12.5:1 appreciation ratio — and that appreciation is not accessible via NUA. Exelon employees should model the EXC-only NUA case carefully against a baseline rollover before making any distribution decisions, and understand that the CEG position requires separate planning (Roth conversion opportunities, tranche selling, charitable giving) entirely outside the NUA framework.

Duke Energy: Progress Energy merger basis

Duke Energy completed its merger with Progress Energy, Inc. on July 2, 2012, creating the largest regulated electric utility in the United States.² For former Progress Energy employees who became Duke Energy employees, the merger exchange ratio and its interaction with NUA basis records requires attention.

The exchange ratio

Under the merger agreement, each share of Progress Energy common stock was converted into 0.87083 shares of Duke Energy common stock. This ratio reflects an adjustment for the one-for-three reverse stock split of Duke Energy shares that took effect immediately prior to the merger close (without the reverse split, the original agreement called for 2.6125 Duke shares per Progress share). The merger was structured as a tax-free reorganization under IRC §368, meaning Progress Energy shareholders generally carry over their Progress Energy cost basis — allocated proportionally — into the Duke shares received.³

What this means for former Progress Energy employees

• Duke shares received at merger carry Progress Energy basis. If a Progress Energy employee had employer match contributions at, for example, an average basis of $40/share in Progress Energy stock, the basis in the Duke shares received at the 0.87083 exchange ratio is $40 ÷ 0.87083 = approximately $45.93/share in Duke shares. Duke Energy (DUK) currently trades around $115–$125/share (verify current price before modeling), producing a 2.5:1 to 2.7:1 ratio on those legacy Progress Energy lots.
• Contributions made directly in Duke stock after the merger carry the Duke stock price at contribution as basis — no merger conversion needed. These are straightforward lot-by-lot calculations.
• Recordkeeper data gaps are possible. The merger happened over 12 years ago, and multiple plan transitions since then may mean the lot-level basis for pre-merger Progress Energy lots is incomplete or estimated. Request the full basis report from Fidelity and verify that the per-lot data explicitly reflects the pre-merger Progress Energy basis (divided by 0.87083 to convert to Duke-share basis), not just an estimated blended figure.

NextEra Energy: the Florida advantage

NextEra Energy (NYSE: NEE) — parent company of Florida Power & Light (FPL) and Gulf Power (now FPL) — is the largest regulated utility in the United States by market capitalization. Long-tenure FPL employees who have accumulated NEE shares through employer match contributions over 25–35 year careers in Florida are among the strongest NUA candidates in the utility sector for a simple reason: Florida has no state income tax, meaning the entire NUA advantage — both the ordinary income tax savings on the cost basis and the LTCG treatment on the appreciation — accrues without state tax erosion.

Stock history and basis context

NextEra Energy completed a 4-for-1 stock split in October 2020. Employees who contributed before the split should note that their per-share basis in plan records may be stated pre-split (divide by 4 for the post-split equivalent) or may already be adjusted — confirm with Fidelity. NEE currently trades around $87–$88/share (July 2026).⁴

On a post-split basis, FPL Group / NextEra match contributions made in the early 2000s carry a basis in the $10–$20/share range, producing 4:1 to 8:1+ ratios at current prices. Contributions made in the 2010–2015 window carry basis in the $25–$45/share range, producing 2:1 to 3.5:1 ratios. The blended ratio for a 35-year employee depends heavily on the distribution of contribution dates and the plan's historical investment allocation to company stock.

FPL plan mechanics (Fidelity)

The NextEra Energy 401(k) Savings Plan is administered by Fidelity NetBenefits. In-kind NEE stock distributions for NUA require calling Fidelity Workplace Investing — not initiating a distribution through the self-service online portal, which defaults to cash liquidation. Request lot-level basis from the NetBenefits portal before the call, and confirm that the distribution specialist can initiate an in-kind transfer to a Fidelity taxable brokerage account.

For the full Fidelity call process, December 31 same-year lump-sum deadline mechanics, and 1099-R Box 6 verification, see Fidelity NUA Distribution Mechanics.

AEP, Southern Company, Dominion, and ConEd

American Electric Power (AEP)

AEP is a major employer across Ohio, West Virginia, Michigan, Indiana, Kentucky, Virginia, Oklahoma, Texas, Louisiana, and Arkansas. The company's operations span both states with no income tax (Texas) and states that tax LTCG as ordinary income (Ohio at approximately 3.5%–3.99%, West Virginia, Virginia). AEP employees in Texas — specifically AEP Texas and Southwestern Electric Power Company operations — capture the full federal NUA advantage with no state income tax erosion, an identical benefit to Florida FPL employees.

AEP's 401(k) plan is administered through Empower. For in-kind distribution mechanics, see Empower NUA Distribution Mechanics. AEP maintains a defined benefit pension for eligible employees, creating the bracket-stacking consideration described in the DB pension section below.

Southern Company

Southern Company (Georgia Power, Alabama Power, Gulf Power, Mississippi Power, and Southern Company Gas) is a major long-tenure employer in the Southeast. The company's 401(k) is administered through Alight Solutions. Georgia (approximately 5.39% on all income) and Alabama (approximately 5% on all income) tax long-term capital gains as ordinary income, meaning Southern Company employees capture federal-only NUA benefit.

Southern Company acquired AGL Resources (Atlanta Gas Light parent) in July 2016 for $66 per share in cash — a fully cash transaction that did not involve SO stock issuance. Former AGL employees who joined Southern Company Gas as employees after the acquisition would have SO stock in their plan from contributions made post-2016, with basis from the SO price at contribution. There is no pre-2016 AGL basis carrying forward into SO shares — AGL shareholders received cash, not stock.⁵

For Alight-specific in-kind distribution mechanics, see Alight NUA Distribution Mechanics.

Dominion Energy

Dominion Energy (Virginia Power, North Carolina Power) is a major long-tenure employer in Virginia and North Carolina. Virginia taxes long-term capital gains as ordinary income at rates up to 5.75%, eliminating the state NUA advantage for Dominion employees. North Carolina's flat income tax rate has been declining (approximately 3.99% in 2026) and applies equally to LTCG and ordinary income — again, federal-only NUA benefit. Dominion's 401(k) plan is administered through Fidelity NetBenefits. See Fidelity NUA Distribution Mechanics for the in-kind transfer process.

Consolidated Edison (ConEd)

ConEd is the regulated utility serving New York City and Westchester County. It is a major employer of IBEW Local 1-2 and other union workers with very long service — careers of 30–40 years are common. New York State tax rates on ordinary income and capital gains are among the highest in the country (top state rate 10.9%), and New York City residents pay an additional local income tax of up to 3.876%. Both state and city treat long-term capital gains as ordinary income. ConEd employees in New York City capture federal-only NUA benefit and should model whether the federal savings — on a position with a favorable ratio — exceed the transaction complexity. For positions with 5:1+ ratios and large balances, the federal savings are still substantial even without state benefit.

DB pension income stacking

Most major regulated utilities have maintained defined benefit pension plans for long-tenure employees — often the single most important factor in timing the NUA election correctly. Pension income creates the bracket-stacking problem: it fills your lower ordinary income brackets before the NUA cost basis distribution adds to them, potentially pushing the cost basis into the 22%–24% bracket rather than the 12% bracket a pension-free retiree would face.

The strategic response:

• Time the NUA election to Year 1 of retirement — before Social Security begins, before RMDs begin. In many utility careers, the pension begins immediately at retirement. The pre-SS, pre-RMD window is usually 2–6 years wide (retiring at 60–63 with SS delayed to 66–70). This is the narrowest income window you will have in retirement.
• Model the bracket ladder explicitly. If pension income is $55,000 and standard deduction (MFJ 2026) is $30,000, your taxable income before the cost basis hit is $25,000 — you still have roughly $72,000 of the 12% bracket and the full 22% bracket remaining. A $120,000 cost basis distribution with a $55K pension would land mostly in the 22% bracket — far better than the 37% rate it might face as a forced RMD in a high-income later year.
• Post-distribution LTCG harvest window depends on total income. With pension income filling the lower brackets, the 0% LTCG bracket ($98,900 taxable income threshold for MFJ in 2026) may be partially consumed, but significant 15% bracket room often still exists — especially before Social Security and RMDs activate.
• Coordination with IRMAA matters. Pension income that already pushes MAGI close to the first IRMAA tier ($212,000 MFJ in 2026 for a two-year-prior-year spike) means the cost basis distribution year may trigger Medicare surcharges for the two subsequent years. Pre-NUA IRMAA modeling should be done alongside the bracket analysis. See NUA and IRMAA.

Utility employees who have no DB pension (newer hire classes at some companies have shifted to enhanced 401(k) matching instead) face a simpler calculation: Year 1 of retirement with minimal other ordinary income is an ideal environment for the cost basis hit.

State tax table for utilities employees

See NUA and State Taxes for a complete analysis of how state treatment changes the NUA vs. rollover breakeven and which states change the minimum viable appreciation ratio.

Worked example: 35-year NextEra Energy engineer in West Palm Beach, FL

Profile: Maria, age 63, retiring from NextEra Energy (Florida Power & Light division) after 35 years as an electrical engineer at the West Palm Beach operations center. Married filing jointly; spouse has $25,000/year in part-time income. Florida resident — no state income tax.

Retirement accounts and pension:

• NextEra Energy 401(k) via Fidelity: 8,000 NEE shares
• Plan cost basis (lot-level, requested from Fidelity): $22/share blended average (contributions concentrated 1995–2012, pre-split equivalent basis in the $7–$15/share range; higher-basis post-split contributions from 2013–2020)
• Total FMV at $88/share: $704,000
• Total cost basis: $176,000 (8,000 × $22)
• NUA amount: $528,000
• Appreciation ratio: 4:1
• Other: $320,000 in Roth IRA (from prior Roth conversions during low-income years); no traditional IRA
• NextEra Energy Pension Plan: $55,000/year (beginning immediately at retirement)

Retirement Year 1 income (Social Security delayed to age 67): Pension $55,000 + spouse income $25,000 = $80,000 gross. Standard deduction MFJ 2026: $30,000. Taxable income before NUA: $50,000.⁶

NUA tax cost in distribution year:

• Cost basis $176,000 added to existing $50,000 of taxable income = $226,000 total ordinary income.
• At 2026 MFJ brackets, the $176,000 basis distribution falls roughly in the 22%–24% range after the first $50K of existing income uses up the 12% bracket space. Estimated federal ordinary income tax attributable to the cost basis: approximately $38,000–$40,000.
• Florida state tax: $0 (no state income tax).
• Total distribution-year federal tax on cost basis: approximately $39,000.

NUA appreciation tax when sold (tranche selling scenario):

• Maria sells $60,000 of NEE stock per year from the taxable brokerage account — well below the 15% LTCG threshold for MFJ ($614,950 combined income in 2026), and managed to stay below the NIIT threshold ($250,000 MFJ) by coordinating with pension income and SS when it starts.⁷
• $528,000 NUA ÷ $60,000/year ≈ 9 years of tranche selling
• At 15% federal LTCG: $528,000 × 15% = $79,200 total LTCG tax
• Florida state tax: $0
• Total NUA path tax (federal only): approximately $118,200

IRA rollover alternative:

• $704,000 rolled to IRA, distributed over retirement as ordinary income at RMD-driven rates. In higher-income years (post-SS age 67, post-RMD age 73), taxable ordinary income from pension + SS + NEE IRA RMDs likely averages in the 22%–28% bracket range.
• At 25% blended average: $704,000 × 25% = $176,000 federal ordinary income tax
• Florida state tax: $0
• Total IRA rollover tax (federal only): approximately $176,000

Federal NUA advantage: approximately $57,800. Even with no state tax advantage (both paths pay $0 to Florida) and a 4:1 ratio that is modest by industry standards, the NUA election converts $528,000 of appreciation from future ordinary income at 25% blended to LTCG at 15% today — saving nearly $58,000 in lifetime federal taxes. If Maria's income management allows some LTCG to fall in the 0% bracket in the pre-SS years (taxable income below $98,900 MFJ in 2026), the savings increase further. The Roth IRA provides tax-free supplemental income in high-income years without adding to MAGI.

When NUA wins for utilities employees

• Long tenure at NextEra, Duke, AEP, or Southern Company with contributions concentrated in the 1990s–early 2000s. A 35-year career with employer match running through the low-price eras of the 1990s and the 2007–2012 market trough can produce blended ratios of 4:1 to 8:1 — enough to produce $50,000–$120,000 in federal savings even with pension income filling the lower brackets.
• Florida or Texas operations. No state income tax means the full federal NUA advantage — both the ordinary income savings on the cost basis and the LTCG treatment on the appreciation — is retained. Ohio, Virginia, Illinois, and Georgia employees still benefit federally but should verify that the federal savings exceed the transaction complexity.
• Pre-Social Security, pre-RMD timing window. Retiring at 60–63 with pension income beginning immediately but SS delayed to 67–70 gives a 4–7 year window where income is relatively low. Using this window to execute NUA (pay basis at lower bracket) and begin tranche selling (harvest NUA appreciation at 15% or 0% LTCG while income is below the threshold) captures the maximum lifetime benefit.
• Estate planning hold. Utility employees holding NEE, DUK, or SO after an NUA distribution who plan to hold the stock until death benefit from a step-up in basis on post-distribution appreciation for heirs, while the NUA layer itself is IRD. Very large positions intended for charitable gifting or estate transfer can make the hold-to-death strategy superior to immediate sale. See NUA and Estate Planning.

When NUA doesn't help for utilities employees

• Exelon employees with only CEG shares worth NUA'ing. As described above, CEG shares in a 401(k) are not employer securities for Exelon employees and cannot be NUA'd regardless of the extraordinary appreciation. If the EXC shares (the only eligible shares) have little appreciation after the spin-off basis allocation, the NUA case may be weak or nonexistent.
• Low appreciation ratio. Utility stocks are regulated, steady earners — they typically don't produce 15:1 or 20:1 ratios. For employees with contributions concentrated in recent years (basis close to current price), NUA's breakeven may not be reached. A 2:1 or better ratio is typically the minimum threshold; below that, the cost basis ordinary income hit often exceeds the LTCG savings on the appreciation.
• Very high pension income pushing basis into 37% bracket. A utility retiree with a generous pension (say, $120,000/year from a 35-year DB plan) may have little remaining lower-bracket room for the cost basis distribution. If the cost basis distribution lands at 32%–37%, it is far less advantageous compared to rolling the stock to an IRA where eventual distributions would face similar rates.
• No in-kind distribution in plan document. Some utility 401(k) plans limit investment options or restrict in-kind employer stock distributions — particularly at smaller municipal utilities or rural co-ops. This must be confirmed in writing from the plan administrator before any distribution paperwork is signed.
• IRA rollover already executed. Rolling employer stock to an IRA permanently eliminates the NUA election under IRC §402(e)(4)(B). For utility employees with large, low-basis NEE or DUK positions, this mistake can cost $40,000–$100,000+ in foregone tax savings. See Should You Roll Over Company Stock?

Questions to ask your plan administrator

1. Does my plan allow in-kind distribution of employer stock shares to a taxable brokerage account? (Confirm this in writing — it is not guaranteed in all utility plans, and some plans hold employer stock in unitized fund form that must be converted to individual shares first.)
2. Can you provide lot-level cost basis for my employer stock — each contribution date, number of shares acquired, and cost per share? (Ask specifically whether the data reflects pre-merger basis allocation for Progress Energy employees now holding Duke shares, or pre-spin basis allocation for Exelon employees.)
3. Are there both EXC and CEG shares in my account? (For Exelon employees: explicitly confirm which shares are EXC vs. CEG, and their respective lot-level basis.)
4. What is the complete lump-sum distribution procedure? What other plan assets must be distributed in the same tax year to satisfy the IRC §402(e)(4) lump-sum requirement?
5. Is there a December 31 deadline for completing the full lump-sum distribution if I initiate the in-kind stock transfer in Q4?
6. How does the 20% mandatory withholding on the cost basis portion work — and can I fund it from outside the plan to avoid liquidating shares?
