Braskem’s October 16 Share Tender Offers Debentures, Not Cash

Braskem shareholders face an unusual decision on October 16: a B3 auction that could transfer as many as 235.4 million shares to Shine I FIP, with payment made in debt securities rather than cash.

For every Braskem share tendered, the bidder is offering two first-series debentures and one second-series debenture issued by NSP Investimentos, the former controlling shareholder that is in judicial recovery. Each debenture has a face value of R$3.08, giving the package a combined nominal value of R$9.24 per Braskem share.

That face value should not be mistaken for a cash price. The offer document itself says the securities’ real economic value is difficult to determine and estimates that it is likely to be much lower than face value because recovery remains highly uncertain. That distinction is the central issue for investors considering the transaction.

What the Braskem tender covers

The unified offer combines a mandatory bid for common shares following a change of control with a voluntary offer for preferred shares. It can cover up to 12,907,078 common shares, 222,004,480 Class A preferred shares and 478,790 Class B preferred shares—a maximum of 235,390,348 shares in total.

If every eligible share is tendered, the bidder would distribute 470,780,696 first-series debentures and 235,390,348 second-series debentures. At stated face value, that is about R$2.18 billion of securities. The notice is explicit, however, that no cash amount was assigned to the consideration when the control transaction was negotiated.

The offer follows the April 17, 2026 judicial share-purchase agreement through which Shine acquired control-related shares from NSP Investimentos. Brazilian takeover rules and Braskem’s bylaws require the follow-on offer to eligible minority holders.

Why the debenture structure matters

A debenture is a debt security: its value depends on the issuer’s ability and obligation to repay, not only on the number printed on its face. Here, the securities mature in 2090—or earlier after a specified default event—and pay 0.1% a year, with monetary adjustment under the terms described in the notice.

The issuer and its parent, Novonor, are both tied to court-supervised restructuring processes. The offer notice says the public information available on the debt issuer is limited and warns Braskem holders to investigate the securities before deciding whether to participate.

This makes the transaction materially different from a conventional tender in which investors compare a fixed cash price with the market price. Shareholders instead have to assess credit risk, restructuring outcomes, liquidity and the practical value of securities received through Brazil’s over-the-counter B3 segment.

Auction timetable and eligibility

The auction is scheduled for 3:00 p.m. Brasília time on Friday, October 16, 2026. Settlement is due by October 21. Investors must use a broker able to operate in both B3’s listed and over-the-counter segments, and they must complete the broker’s qualification process by the deadline described in the offer notice.

The offer is directed to eligible Braskem shareholders able to participate in Brazil. U.S. persons cannot take part, and other non-resident investors must comply with the laws that apply to them. The auction can be followed through the BRKM3L, BRKM5L and BRKM6L codes.

If the transaction leaves less than 15% of a relevant share class in public circulation, additional sell-out rights may apply under the procedures and dates in the notice. The filing also allows certain post-auction sales through November 16.

Why Braskem’s ownership matters beyond the stock market

Braskem describes itself as the largest thermoplastic-resin producer in the Americas, with more than 20 million tonnes of annual capacity across resins and other chemicals and customers in more than 70 countries. Its polyethylene, polypropylene, PVC and chemical products feed packaging, construction, automotive, consumer-goods and industrial supply chains.

The October tender does not itself change factory output or customer contracts. But it is an important next step in Braskem’s ownership transition, and the unusual consideration exposes how the restructuring of its former controlling group still intersects with one of the Americas’ largest plastics producers.

What happens next

The immediate test is how many minority holders qualify and choose to tender on October 16. Any amendment, postponement or change to the consideration must be disclosed through the formal channels set out in the notice.

The transaction should therefore be read as an open tender process, not a completed acquisition of all remaining shares. Investors considering participation should use the full official notice and their own legal, tax and financial advice; this article is reporting, not an investment recommendation.
