Santander Brasil Share Swap Premium Falls From 15% to About 1.6%

Santander Brasil Share Swap Premium Falls From 15% to About 1.6%

A deal announced at a 15 percent premium is now worth barely more than the market price. The offer document says so itself.

If you hold Santander Brasil units, the Santander Brasil share swap is no longer the deal that was announced in July. A unit is a bundle of one common and one preferred share. A unit is a bundle of one common and one preferred share. The exchange ratio has not moved. The share prices have. Their moves leave very little extra value for anyone thinking of accepting.

Key Facts

  • The country — Brazil, 210 million people and the largest economy in Latin America, with a policy interest rate of 13.75 percent that makes its banks unusually profitable and its shares unusually cheap.
  • The company — Santander Brasil is the Brazilian arm of Spain’s Banco Santander, one of Brazil’s largest private banks, with 76 million customers and about 49,000 staff.
  • The background — the Spanish parent already owns about 89.7 percent of it. In July it offered to swap the remaining 10.3 percent for shares in itself, at what it called a 15 percent premium.
  • What happened — on 21 September it filed the paperwork with US and Brazilian regulators. Nothing has been approved, and no deadline has been set.
  • Why it matters now — the Brazilian shares rose 19 percent since July while the terms stayed fixed. On 15 September prices the premium was about 1.6 percent, not 15.
  • What it is not — a delisting. The prospectus says the shares keep trading in São Paulo and that holders who refuse cannot be forced out.
  • What it means for you — accepting swaps a Brazilian bank for euro exposure to a global parent. Refusing keeps the Brazilian exposure in a market with fewer buyers.

What was filed on Monday

Banco Santander, the Spanish parent, filed a Form F-4 registration statement with the US Securities and Exchange Commission on 21 September. It is marked subject to completion and has not been declared effective. On the same day Santander Brasil disclosed requests to Brazil’s securities regulator, the CVM, and to the São Paulo exchange, B3.

There are four requests. Register the Spanish parent as a foreign issuer in Category A. Register a BDR programme. Admit those BDRs to trading on B3. And register the Brazilian offer itself. A BDR, or Brazilian Depositary Receipt, is a certificate traded in São Paulo and backed by a share held abroad. Here each one represents a single new Santander share. Holders are not shareholders of the parent directly, and depend on a Brazilian depositary bank to pass on dividends and voting instructions.

None of these registrations has been granted yet. Santander’s own document says it expects to obtain them before the offer starts. Until then there is no offer to accept and no deadline to miss.

Why the Santander Brasil share swap looks different now

The terms were set on 30 July, using that day’s closing prices. Santander shares closed at 12.248 euros (about US$14.06 at that day’s rate). Santander Brasil units closed at R$25.25 (about US$4.97). The ratio of 0.4056 parent shares per unit implied R$29.04 (about US$5.72), a 15 percent premium.

Then the Brazilian shares went up. By 15 September the units were at R$30.07 (about US$5.84), while the parent rose only 3.4 percent to 12.67 euros (about US$14.62). On those prices the premium is about 1.6 percent on units and 1.4 percent on common shares. On the New York receipts it is 1.2 percent. The offer document publishes these numbers itself, and converts reais at a rate of 5.1487 to the US dollar for 15 September.

It also concedes two more. Measured over the twelve months to 30 July, the offer is a 3.6 percent discount to the average unit price. Against the high in that period it is a 22.6 percent discount. JPMorgan noted that Santander’s comparable 2014 swap offer carried an initial 20 percent premium.

The timing question analysts raised

The reference date was the day after Santander Brasil reported a weak second quarter. Recurring profit came in at R$3.0 billion (about US$583 million), down 17.6 percent on the year. The units fell 7.37 percent on the news. The premium was then struck against that lower price.

JPMorgan called the proposal disappointing next to 2014. Citi measured it against the pre-results price and put the effective premium near 5 percent. BTG Pactual said the timing clearly favours the Spanish parent, which is paying with its own richly valued shares. Banco Safra called the offer a soft anchor for the price, not the firm floor a cash offer would provide.

There is a detail on the valuation too. UBS BB, a brokerage owned by UBS and Banco do Brasil, cut its rating on the units in late August. In September Santander hired it as the independent appraiser. It delivered its report on 18 September. The prospectus states that the appraiser’s duties are owed to Santander alone. It also says the report is not a fairness opinion, an independent view that the price is fair to shareholders.

What happens if you do nothing

The offer does not take the bank private. Santander’s own release says it does not seek a delisting. The prospectus confirms that the shares and units will keep trading on B3 after completion, in its traditional segment.

More to the point, holders who refuse cannot be forced out. The registration as a listed company is not being cancelled. So the parent has no right to a squeeze-out, a forced buyout of remaining holders, or a compulsory redemption. There are no appraisal rights either, meaning no right to demand a court-set cash value. Brazilian law does not attach them to a voluntary tender offer.

What does exist is a second chance. Less than 15 percent of the shares will sit in unrelated hands after the auction. That triggers a rule giving every holder who did not tender 30 calendar days to exchange with Santander on the same terms. It is not automatic. Brazilian holders must give written notice and sign the agreement at a branch, in person or through an attorney. The ratio is not adjusted in the meantime for the Selic,Brazil’s benchmark interest rate. That is because the payment is in shares rather than cash.

Why this matters beyond the shareholder register

The parent already owns about 89.7 percent of the capital. The free float, the shares in outside hands, is roughly 10.3 percent. It is worth around R$11.5 billion (about US$2.2 billion), against a market value of R$111.4 billion (about US$21.6 billion). So the money involved is modest next to what the deal does to liquidity.

Santander Brasil trades about R$130 million (about US$25 million) a day, on a 30-day average. Itaú, Brazil’s largest private bank, trades R$1.09 billion (about US$211 million). HSBC cut the stock to hold in mid-September on that point, expecting trading liquidity to fall to minimum levels. It put its price target at R$31 (about US$6.02).

For anyone saving or investing in Brazil, that is the real consequence. Santander Brasil had 76.2 million customers and about 47,300 staff at the end of June. It becomes progressively harder to own as a Brazilian asset. Accepting swaps a bank geared to Brazilian interest rates for euro exposure to a global parent. Refusing keeps the Brazilian exposure, but in a market with fewer buyers on the other side when you want out. Neither choice is clearly right, and the shrinking premium is what makes it a choice at all rather than a windfall.

Frequently Asked Questions

What exactly is being offered for each Santander Brasil unit?

Each unit, ticker SANB11, would be exchanged for 0.4056 Banco Santander shares. They would be delivered as a BDR in Brazil or an ADS (American Depositary Share) in New York. Common and preferred shares get 0.2028 each. The ratio has not changed since it was announced on 30 July.

Will Santander Brasil be taken off the stock exchange?

No. The prospectus states the shares and units continue trading on B3 in the traditional segment after the offer. The New York receipts are different and may be delisted depending on how many holders accept.

Can I be forced to sell if most other holders accept?

No. Because the company is not cancelling its registration, there is no squeeze-out available under Brazilian law. Holders who decline also get a 30-day window after the auction to exchange on the same terms if they change their mind.

When would any of this actually happen?

No expiration date has been set, and the registrations have not been granted. Santander expects completion in the first half of 2027. Once launched, the Brazilian offer must stay open for at least 20 calendar days.
