Index Rebalance

Naturgy Energy Group SA / Index Rebalance

<ul>
<li>Following the June IBEX review, Naturgy’s free-float coefficient rises from 20% to 60%, potentially increasing its benchmark weight from roughly 0.6% to around 1.8%.</li>
<li>We estimate incremental IBEX-linked demand of €180–300m for Naturgy, versus €30–55m for Indra and €10–20m for Solaria, based on benchmark rebalancing requirements.</li>
<li>The IBEX 35 composition remains unchanged, but the coefficient revisions create a meaningful rebalance. For passive investors, the June review is primarily a Naturgy event.</li>

Following the June IBEX review, Naturgy’s free-float coefficient rises from 20% to 60%, potentially increasing its benchmark weight from roughly 0.6% to around 1.8%.
We estimate incremental IBEX-linked demand of €180–300m for Naturgy, versus €30–55m for Indra and €10–20m for Solaria, based on benchmark rebalancing requirements.
The IBEX 35 composition remains unchanged, but the coefficient revisions create a meaningful rebalance. For passive investors, the June review is primarily a Naturgy event.


IBEX Review: Naturgy Emerges as the Main Beneficiary

<ul>
<li>CVC exits Naturgy completely via €3.1bn ABB; investable float rises toward 47%, completing the transition from constrained utility to fully benchmark-relevant large-cap.</li>
<li>3-Month ADTV reaches €62m versus €13–15m historically, supporting higher MSCI and IBEX 35 weights, tighter spreads, stronger ETF replication and larger passive ownership.</li>
<li>We estimate total passive and index-sensitive demand could now reach €350–475m, while dividend yields of 6.3–6.7% continue providing valuation support after the placement discount.</li>
</ul>


CVC exits Naturgy completely via €3.1bn ABB; investable float rises toward 47%, completing the transition from constrained utility to fully benchmark-relevant large-cap.
3-Month ADTV reaches €62m versus €13–15m historically, supporting higher MSCI and IBEX 35 weights, tighter spreads, stronger ETF replication and larger passive ownership.
We estimate total passive and index-sensitive demand could now reach €350–475m, while dividend yields of 6.3–6.7% continue providing valuation support after the placement discount.


Naturgy: CVC Exit Completes Float Reset as Index Weight Upside Accelerates

Event-Driven

<ul>
<li>Criteria raises stake to 28.5% via BlackRock ABB, absorbing 2.5% of the block and confirming strategic support while lifting Naturgy’s free float to ~33.3%, versus ~11% before the 2025 auto-OPA.</li>
<li>Float expansion remains ongoing rather than exhausted. Criteria’s partial participation suggests disciplined accumulation, leaving room for further supply absorption should CVC (13.8%) ultimately pursue an exit.</li>
<li>At 33.3% float, Naturgy’s index relevance continues to rise; a full CVC exit could lift float toward ~47%, materially increasing float-adjusted market cap and reinforcing the €250–350m passive demand envelope.</li>

Float expansion remains ongoing rather than exhausted. Criteria’s partial participation suggests disciplined accumulation, leaving room for further supply absorption should CVC (13.8%) ultimately pursue an exit.
At 33.3% float, Naturgy’s index relevance continues to rise; a full CVC exit could lift float toward ~47%, materially increasing float-adjusted market cap and reinforcing the €250–350m passive demand envelope.


Naturgy: Criteria Raises Stake to 28.5% as Float Expands

<ul>
<li>BlackRock’s full exit removes the most visible overhang, while structurally higher free float (potentially ~35–40%) repositions Naturgy from index eligibility repair to sustained weight expansion across MSCI and Ibex benchmarks.</li>
<li>Three-Month ADTV of €31.55m confirms a durable liquidity reset, materially improving block absorption capacity and supporting potential €250–350m passive inflows under higher float-adjusted index weight scenarios.</li>
<li>At €24.78, Naturgy trades on ~12x forward earnings with 7.2–7.8% dividend yields, providing downside protection as index-driven reweighting and shareholder normalisation underpin a €27.50 target.</li>
</ul>

Naturgy: From Overhang to Index Weight Expansion

<ul>
<li>Naturgy's float rises to 28.8% after stake shifts by BlackRock, Criteria, and CVC–Alba; MSCI and Ibex index weights set to increase, with passive flows and liquidity surging.</li>
<li>3-Month ADTV jumps to &gt;€45M, more than tripling YoY, reinforcing Naturgy’s visibility in tracker portfolios and enabling higher lendable supply for ETFs and Delta One desks.</li>
<li>Criteria likely buyer up to 29.9%; CVC’s revised pact signals exit intent. Combined with IFM’s known interest, shareholder churn may boost volume and support short-term re-rating.</li>
