Rhea-AI Filing Summary

Sandisk Corporation is alerting stockholders to an unsolicited “mini-tender” offer by Tutanota LLC to purchase up to 100,000 shares of Sandisk common stock at $1,150.00 per share. These shares represent less than 0.07% of Sandisk’s common stock as of April 24, 2026.

The offer price is conditioned on Sandisk’s closing share price exceeding $1,150.00 on the last trading day before expiration, which Sandisk explains would result in a below-market price unless the condition is waived. Sandisk does not endorse the offer, is not affiliated with Tutanota, and recommends that stockholders do not tender their shares.

Stockholders who have already tendered may withdraw their shares any time before the offer’s scheduled expiration at 5:00 p.m. Eastern Time on May 20, 2026, as described in Tutanota’s documents. Sandisk’s press release also points to SEC and industry guidance warning investors about risks associated with mini-tender offers.

"unsolicited “mini-tender” offer by Tutanota LLC (“Tutanota”) to purchase up to 100,000 shares"
A mini-tender offer is a proposal to buy a relatively small slice of a company’s outstanding shares, typically under the regulatory threshold that triggers full public-offer rules. It matters to investors because these offers usually come with fewer disclosure and procedural protections than large takeovers, can be made at prices below current market value, and may temporarily restrict or complicate your ability to sell—think of it as an unsolicited small buyout attempt that lacks the safeguards of a full-scale offering.

Sandisk Recommends Stockholders Reject “Mini-Tender” Offer by Tutanota LLC

MILPITAS, Calif. - May 14, 2026 - Sandisk Corporation (Nasdaq: SNDK) (“Sandisk”) today announced that it recently became aware of an unsolicited “mini-tender” offer by Tutanota LLC (“Tutanota”) to purchase up to 100,000 shares of Sandisk’s common stock at an offer price of $1,150.00 per share. The shares subject to Tutanota’s offer represent less than 0.07% of Sandisk’s common stock as of April 24, 2026.

The offer price of $1,150.00 per share is conditioned upon, among other things, the closing price per share of Sandisk’s common stock exceeding $1,150.00 per share on the last trading day before the offer expires. This means that unless this condition is waived by Tutanota, Sandisk stockholders who tender their shares in the offer will receive a below-market price. Tutanota can extend the offer for successive periods of 45 to 180 days, in which case payment would be delayed beyond the scheduled expiration. Stockholders who have already tendered their shares may withdraw them at any time by providing notice in the manner described in the Tutanota offering documents prior to the expiration of the offer, which is currently scheduled for 5:00 p.m., Eastern Time, on Wednesday, May 20, 2026, unless extended. Sandisk recommends that stockholders who have not responded to Tutanota’s offer take no action.

Sandisk does not endorse Tutanota’s unsolicited mini-tender offer and is not affiliated or associated in any way with Tutanota, its mini-tender offer, or the offer documentation.

Tutanota has made similar unsolicited mini-tender offers for stock of other public companies. As Tutanota’s mini-tender offer is for less than five (5) percent of Sandisk’s outstanding shares, it is not subject to many of the disclosure and procedural requirements of Securities and Exchange Commission (“SEC”) rules that are designed to protect investors. The SEC has cautioned investors about mini-tender offers, noting that “some bidders make mini-tender offers at below-market prices, hoping that they will catch investors off guard if the investors do not compare the offer price to the current market price.” The SEC’s guidance to investors on mini-tenders is available at https://www.sec.gov/investor/pubs/minitend.htm.

Sandisk encourages brokers and dealers, as well as other market participants, to review the SEC’s letter regarding broker-dealer mini-tender offer dissemination and disclosures at https://www.sec.gov/divisions/marketreg/minitenders/sia072401.htm and the NASD Notice to Members 99-53 issued in July 1999 regarding guidance to members forwarding mini-tender offers to their customers, which can be found at https://www.sec.gov/divisions/marketreg/minitenders/sia072401.htm.

Stockholders should obtain current market quotations for their shares, consult with their broker or financial advisor, and exercise caution with respect to Tutanota’s mini-tender offer.

Sandisk requests that a copy of this news release be included with all distributions of materials relating to Tutanota’s mini-tender offer related to Sandisk’s common stock.

FAQ

What unsolicited mini-tender offer is Sandisk (SNDK) warning about?

Sandisk is warning stockholders about an unsolicited mini-tender offer from Tutanota LLC to buy up to 100,000 Sandisk shares at $1,150.00 per share. The company states it does not endorse the offer and is not affiliated with Tutanota or its offer documents.

How large is the Tutanota mini-tender offer relative to Sandisk (SNDK) shares?

Tutanota’s mini-tender seeks up to 100,000 Sandisk common shares, representing less than 0.07% of Sandisk’s outstanding stock as of April 24, 2026. This small size keeps the offer below certain SEC disclosure and procedural requirements that typically apply to larger tender offers.

Why does Sandisk say the Tutanota mini-tender could be below market price?

The $1,150.00 per-share offer is conditioned on Sandisk’s closing share price exceeding $1,150.00 on the last trading day before expiration. Sandisk explains that, unless Tutanota waives this condition, stockholders tendering shares would receive a price below the then-current market price.

When does the Tutanota mini-tender offer for Sandisk (SNDK) stock expire?

The mini-tender offer is currently scheduled to expire at 5:00 p.m. Eastern Time on Wednesday, May 20, 2026, unless Tutanota extends it or terminates it earlier. Sandisk notes that Tutanota can extend the offer in 45- to 180-day periods, delaying payment accordingly.

Can Sandisk (SNDK) stockholders withdraw shares already tendered to Tutanota?

Yes. Sandisk states that stockholders who have already tendered shares to Tutanota may withdraw them at any time before the offer expires. Withdrawals must follow the procedures described in Tutanota’s offering documents for the mini-tender offer.

What guidance does Sandisk reference about mini-tender offers?

Sandisk cites SEC guidance warning that some mini-tender bidders offer below-market prices, potentially catching investors off guard. It directs investors, brokers, and dealers to specific SEC and NASD resources that discuss mini-tender offer dissemination, disclosures, and best practices when forwarding such offers to customers.
