Filing Reveals Potential 9.1% Stake for SK hynix in Penguin Solutions
Key Facts
SK hynix disclosed beneficial ownership of 9.1% in Penguin Solutions in a Schedule 13D filed with the U.S. Securities and Exchange Commission, through 6,096,103 common shares that may be acquired upon conversion of preferred stock. The filing, published on November 3, 2026, reveals an investment linked to a convertible instrument, not a direct purchase of common shares in the market. The preferred stock belongs to SHIFTIX1, an indirectly owned, wholly owned subsidiary of HYAICO, a subsidiary in which SK hynix holds a majority stake. The disclosed percentage is therefore tied to conversion rights into common shares, while ownership of the preferred stock remains with SHIFTIX1. The filing places the transaction in the context of the companies' commercial relationship and also gives it governance implications.
The ownership percentage was calculated based on 60,616,641 Penguin Solutions common shares outstanding on October 26, 2026, plus the shares that could be issued upon conversion of the preferred stock. This means the percentage includes shares that may be acquired in the future and does not, on its own, describe holdings of common shares outstanding on that date. According to the filing, SHIFTIX1 purchased the preferred stock from Astra AI Infra for $377,162,666 in cash on October 29. The purchase was made under a stock transfer agreement dated July 27, 2026. These dates show a sequence that began with the transfer agreement, followed by the transfer of the preferred stock and then the disclosure of beneficial ownership.
The preferred stock had an aggregate liquidation preference of $200 million on October 29, 2026, while the initial conversion price was set at $32.80784 per share, according to the U.S. Securities and Exchange Commission. These values are subject to adjustment under the terms set out in the filing, so the applicable conversion price may change. The preferred stock carries cumulative dividends at an annual rate of 6%, payable quarterly in cash or shares, at Penguin Solutions' election and subject to the specified terms. This periodic return adds a financial dimension to the investment alongside the ability to convert the shares into common equity. The instrument thus combines dividends and conversion rights, with its details governed by the terms of issuance.
The investor's rights extend beyond the financial terms: an investors' agreement gives SK hynix and its affiliates the right to nominate one director to Penguin Solutions' board as long as their holdings represent at least 5% of the outstanding common shares. If the board has 12 or more members, the agreement allows them to nominate two directors. This right remains tied to maintaining the specified ownership threshold, according to the Schedule 13D. The agreement also gives investors the right to participate in new securities offerings, subject to its terms. These arrangements provide channels for participation in governance and financing, alongside the economic exposure arising from the convertible preferred stock.
The transaction follows a strategic collaboration announced by Penguin Solutions, SK Telecom and SK hynix on January 9, 2025, to develop and deliver comprehensive solutions for AI data centers. SK hynix said the collaboration includes work to develop next-generation memory products for data centers, with the aim of strengthening its competitiveness in high-bandwidth memory. The collaboration places the two companies within a joint effort to develop infrastructure related to AI data centers. In its fiscal 2026 results, Penguin Solutions reported sales of $1.73 billion, up 26% year over year. The company also said in October that it had won six new AI data center infrastructure customers during the fiscal fourth quarter, including four emerging cloud service providers.
Penguin Solutions raised its fiscal 2027 outlook to sales growth of about 40%, with a margin of 10 percentage points, and forecast GAAP diluted earnings per share of $3.50. The outlook puts the company's future performance in the context of its expansion in AI infrastructure, also reflected in its wins of new customers during the fiscal fourth quarter. The mandatory conversion terms allow the company to force conversion only after the second anniversary of December 13, 2026. This requires the volume-weighted average price to equal or exceed 150% of the applicable conversion price during any period of 15 consecutive trading sessions. Investors may convert the preferred stock at any time, while automatic conversion remains subject to those timing and price conditions.
