NEXA · Nexa Resources S.A.

Current Thesis

Nexa Resources' thesis is a Boliden-linked minority tender that delivers cash consideration above the September reference close; completion on the announced terms would validate it, while a weekly close below $11 would invalidate the market case. The transaction framework remains the central story from the September note, but the adjusted reference close was $13.01 on 2026-09-18, versus $13.80 on 2026-09-04. Those observations establish weaker price support; they do not establish that the transaction is failing.

The agreement announced on 2026-08-27 exchanges Votorantim's 64.68% controlling interest for newly issued Boliden shares. The subsequent minority tender uses the same 0.250 exchange ratio and Boliden's preceding 20-day volume-weighted average price. The announcement-implied $15.29 per Nexa share is therefore a historical valuation, not a fixed cash entitlement. Nexa transaction disclosure, 2026-08-27.

As an inference, the narrative is maturing — the definitive agreement dates to 2026-08-27, while the 2026-09-18 reference close remains below the September note's reference price. The available evidence does not establish expanding participation. The case succeeds if the announced transaction produces a completed minority tender above $13.01 before the published price invalidation fires; the evidence supports medium conviction because the controlling seller is committed but approvals, timing and cash consideration remain unresolved.

Bullish and bearish views on Nexa Resources S.A.

The model's bull view on Nexa Resources S.A. (NEXA), in brief: The controlling seller has committed. Nexa's 2026-08-27 disclosure identifies a definitive agreement covering Votorantim's 64.68% interest. This removes uncertainty over that seller's willingness to transact, although completion remains conditional. Nexa disclosure. Minority… The bear view: The cash amount remains variable. The 2026-08-27 terms link minority consideration to Boliden's share price before closing. A final tender price at or below the 2026-09-18 Nexa close of $13.01 would defeat the positive-convergence case even if the transaction completed. Nexa… Both cases follow in full.

Bull Case

• The controlling seller has committed. Nexa's 2026-08-27 disclosure identifies a definitive agreement covering Votorantim's 64.68% interest. This removes uncertainty over that seller's willingness to transact, although completion remains conditional. Nexa disclosure.
• Minority consideration has a mechanism. The 2026-08-27 agreement provides for a voluntary cash tender following closing, with consideration linked to the 0.250 exchange ratio and Boliden's pricing window. This supports a transaction-convergence thesis; termination or removal of the tender obligation would break it. Nexa disclosure.
• Reported earnings support standalone value. Nexa's 2026-08-05 second-quarter release reported revenue of US$908 million, up 28% year over year, and net income of US$98 million versus US$13 million a year earlier. These are operating results, not evidence of a guaranteed equity floor.

Bear Case

• The cash amount remains variable. The 2026-08-27 terms link minority consideration to Boliden's share price before closing. A final tender price at or below the 2026-09-18 Nexa close of $13.01 would defeat the positive-convergence case even if the transaction completed. Nexa disclosure.
• Approvals remain conditions to completion. Boliden's 2026-08-27 announcement requires shareholder authorization for the consideration shares, Nexa shareholder approval of a replacement board, and regulatory approvals. A rejected authorization or announced failure of a required approval would break the completion thesis. Boliden announcement.
• Operating momentum is uneven. The second-quarter operating figures cited in the 2026-09-05 coverage put Aripuanã zinc output at 8,800 tonnes and average utilization at 71%, below the first-quarter production record of 13,000 tonnes. A subsequent quarter below those second-quarter readings would weaken the operating recovery supporting standalone value.

Setup & Price Structure

Measured as of 2026-09-18, the adjusted daily close was $13.01, the trailing three-month price change was negative 5.8%, and the shares stood 21.4% below the supplied 52-week high of $16.55. The 14-day relative strength index was 47.0. These readings do not demonstrate an accelerating momentum leg.

The $11 level remains the research boundary associated with the April breakout area in the 2026-09-05 published note. It is a thesis threshold, not a newly measured moving average or evidence that support has been retested successfully. The supplied observations are insufficient to establish a new base.

For positioning, Boliden's 2026-08-27 announcement reported 35.32% of Nexa shares held by minority investors. That describes ownership concentration; it does not measure speculative crowding. Current short interest, fund flows, moving-average distance and a representative retail-sentiment sample are missing, so no crowding conclusion is supported. Boliden announcement.

Catalyst Calendar (next 30 days)

• 2026-09-20 through 2026-10-20: No company-confirmed transaction event date was established in the reviewed disclosures. The ~2026-09-30 extraordinary general meeting estimate in the 2026-09-05 note remains unconfirmed and is not treated as a scheduled catalyst.
• 2027-03-31, guided-quarter endpoint: Boliden's 2026-08-27 announcement expects closing during the first quarter of 2027; this date marks the end of that window, not a scheduled closing day. Closing starts the contractual minority-tender timetable of 30 days, or 60 days in specified circumstances. A revised timetable beyond that quarter would invalidate the announced timing assumption. Boliden announcement.

What Would Change Our Mind

Loss of the April breakout area would end the published market case: a weekly close below $11 is the observable invalidation. That boundary is retained from the 2026-09-05 research framework and does not predict whether the legal transaction eventually closes.

The transaction case would also fail if the agreement were terminated, a required approval were definitively refused, or the completed minority tender paid no more than the 2026-09-18 reference close of $13.01. Conversely, disclosed approvals and tender documents establishing consideration above that reference would strengthen the case; completion and payment would settle it. These tests follow the conditional tender structure announced on 2026-08-27.

Correlation Notes

This is a single-name transaction setup. The 2026-08-27 tender formula creates direct economic exposure to Boliden's share price during the pricing window and to the Swedish-krona translation into US dollars. That contractual linkage is not a measured daily-return correlation. Boliden announcement.

Standalone operating exposure remains relevant: Nexa's 2026-08-05 results reported stronger revenue, while the second-quarter Aripuanã figures showed lower zinc output than the first-quarter record. No matched return series for Nexa, Boliden, zinc or currencies is supplied, so neither a correlation coefficient nor a claim of one-for-one tracking is supported.
