NextEra shareshave stabilized at a ~5% 2029 P/E premium versus utilities peers.Initial data points for the mergerapproval are mixed. Dominion quantified 'only' ~$10 monthly residential bill credit, below the ~$30/monthJEFe we initially calculated. We have seen some opposition to the transaction on the national stagebut in Virginia somewhat positive on the margin. Adverse draft text for the VA merger review timelinewas removed in the final bill. VA Governor has shown support for Dominion by appointing Virginia utilityPresident to the Board of Virginia Tech, despite Clean Energy Virginia opposition. Looking for clues in the proxy.For Dominion shareholders, investors are focused on what partiesexpressed interest in acquiring Dominion aside from NEE. For NextEra, the focus will be on whetherNEE's forecasts supports an 8.5% EPS CAGR or better relative to the 8%+ standalone guidance.Investors are growing more comfortable with NEE valuation. With the spread compressing, the bull thesisfor D shares relies more on NEE re-rating higher from data center announcements.

Every 50bp changein FERC ROE represents ~5¢ EPS (1.4%) and 10bp FFO / Debt.VEPCO has a 10.9% base ROE whichhas elevated risk of a separate complaint; however, we believe the base ROE is solidly in the zone ofreasonableness.

We see a positive risk/reward in both deal and no-dealscenarios. Dominion benefits from the 2026 Virginia storage mandate whichleads to more capex and earnings growth. In a standalone scenario, D benefitsfrom the NEE break fee and is able to grow EPS at 8-9% vs ~6-7% on astandalone basis. The investment case is centered on Virginia data centersrequiring transmission & generation investments. The unregulated businessvalue is primarily via Millstone nuclear with upside optionality. Upside Scenario,$81, +16% Downside Scenario,$66, -5% Base Case,$79, +13% Upsidecase could be achieved via NextEraEnergy positively re-rating towards its highs of~$95-98/shfrom April-May.NEE data centerannouncements could be a catalyst for returningto the relative highs. NextEra positively re-rates to a +14% premium,our last published JEF base case. This wouldrepresent ~$96/sh for NEE and $79 for D at the0.8138 ratio. There is a $2.67/sh (4%) annualdividend payment in addition. NextEra negatively derates to its relative P/E lowsof ~5% vs utility peers. This would represent ~$81/sh for NEE and $66 for D at the 0.8138 ratio. T
