Growth against the P/E multiple. Up and to the right is cheaper and faster — the quality-growth idea in one picture. Points beyond the axis are pinned to the edge and marked off-scale rather than allowed to compress everything else.

Utilities - Regulated Electric · $79.76 · beta 0.59
Why now
Utilities - Regulated Electric · market cap $80.2b. 16% off the 52-week high of $94.64. Revenue -7% — in contraction; any catalyst that reverses this triggers re-rating. 5 sell-side analysts publish a mean 1-yr target of $90.89 (implying +14% upside).
Moat
Net margin 16% beats the market median by a meaningful margin — the company is keeping more of every revenue dollar than the average S&P constituent. $80.2b market cap gives the company enough scale to absorb fixed costs that subscale competitors can't, without yet being so large that growth has to come from acquisition.
Risk
Revenue contracting -7% — the operational turn is not yet visible in the top line. Dividend payout 71% of earnings on a 4.0% yield — distribution coverage is thin; one earnings stumble could force a dividend cut. ROE 8% is below the long-run sustainable threshold of ~10% — capital efficiency would need to improve for the equity base to compound at the market rate.
VSTVistra Corp.
Utilities - Independent Power Producers · $136.21 · beta 1.43
Why now
Utilities - Independent Power Producers · market cap $45.7b. Down 38% from 52-week high of $219.82 — deep drawdown territory. Revenue growing +19%, comfortably above the S&P median. PEG 0.41 — paying under fair value for the growth rate. 18 sell-side analysts rate this a Strong Buy with a mean 1-yr target of $219.72 (implying +61% upside).
Moat
ROE 40% — top-decile capital efficiency. Either pricing leverage, low capital intensity, or aggressive buybacks; the durability story depends on which. FCF converts 102% of net income — earnings translate cleanly into cash, a sign that working capital and capex are well-disciplined.
Risk
D/E 3.73 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer. Down 38% from the 52-week high — the market is pricing in something the screen can't see; verify the bear case before sizing up. Beta 1.43 implies above-market volatility — position-size to the drawdowns this name will produce in a market correction, not to its bull-case return.

Where NGG and VST diverge

On the headline score the gap is 16.2 points in favor of VST. They get there differently, though — each leads on a different pillar, so the better pick depends on which you weight.

Pillars run 0–100 against sector peers, so a score is a statement about a company relative to its own industry rather than to the other name here. A wide Value gap usually means the market already prices the difference in quality or growth — which is the trade-off this comparison comes down to.
