Sandisk Corporation has issued a strong warning to its shareholders, urging them to reject an unsolicited mini-tender offer from Tutanota LLC. The offer, which seeks to purchase up to 100,000 shares at $1,150 each, is roughly 17% below Thursday's closing price of $1,382.72. The company emphasized that the bid represents less than 0.07% of its outstanding common stock as of April 24, and cautioned that accepting could result in selling shares well below current market value.
This mini-tender offer is set to expire at 5:00 p.m. Eastern on May 20, unless extended by Tutanota. Sandisk noted that the offer includes a condition requiring Sandisk shares to close above $1,150 on the final trading day before expiration. Additionally, Tutanota retains the right to extend the deadline in increments of 45 to 180 days, potentially delaying payment to shareholders. The company clarified that it has no affiliation with Tutanota and advised shareholders who have not yet responded to simply refrain from taking any action. Those who have already tendered their shares still have time to withdraw before the offer expires.
Mini-tender offers, which target less than 5% of a company's shares, often bypass the rigorous disclosure and regulatory scrutiny required for larger tender offers. The Securities and Exchange Commission (SEC) has previously warned investors to carefully evaluate such offers before agreeing to sell, as they can be structured to take advantage of market conditions.
The warning comes amid a period of significant growth for Sandisk, driven by surging demand for AI memory chips. The company's shares have rallied sharply following its separation from Western Digital in February 2025, when it began trading as an independent public company on Nasdaq under the ticker SNDK. Sandisk has pivoted from its traditional role as a consumer flash drive maker to a key player in the AI infrastructure market, with its NAND flash memory increasingly used in data centers for AI workloads.
Sandisk reported robust fiscal third-quarter results, with revenue of $5.95 billion—nearly double the previous quarter—and GAAP net income of $3.62 billion. Data-center revenue surged 233% sequentially. For the fourth quarter, the company forecasts revenue between $7.75 billion and $8.25 billion. As of April 3, Sandisk reported $41.6 billion in remaining performance obligations, largely from long-term customer contracts, though only about 15% is expected to be recognized as revenue in the coming year.
CEO David Goeckeler has emphasized the company's goal of stabilizing the memory sector's notorious boom-bust cycles. In a recent interview with Reuters, he stated, “The bane of this industry has been the boom-bust cycle. We want consistent, predictable economics.”
The memory market faces potential disruptions from a looming strike at Samsung Electronics' union in South Korea, planned to begin May 21. Analysts at NH Investment & Securities noted rising concerns over delivery reliability and the possibility that rivals could benefit from the uncertainty. JPMorgan estimated the strike could impact Samsung's operating profit by 21 trillion to 31 trillion won. For Sandisk, tighter supply could boost prices, but also inject additional volatility into a sector already racing to meet AI-driven demand.
Sandisk also faces execution risks. Its latest 10-Q filing warns that missing delivery targets under long-term contracts could lead to price cuts, penalties, or loss of contracts. Conversely, customers backing out on purchase commitments could force Sandisk to sell inventory at steep discounts, impacting margins.
For now, shareholders are focused on the immediate concern: Tutanota's unsolicited, below-market offer. The broader debate for SNDK stock remains centered on whether AI-driven demand can sustain memory prices and support the stock's recent rally.
