The midpoint of the company's revenue forecast was below what analysts had been modeling

Sandisk's stock was falling on Wednesday afternoon.

Shares of Sandisk were set to extend their declines after the memory-chip maker's guidance for the September quarter missed Wall Street's high expectations.

Sandisk $(SNDK)$ set September-quarter revenue guidance between $10.3 billion and $10.8 billion, which at the midpoint was below the FactSet consensus for $10.8 billion. The company's outlook for adjusted earnings per share was between $44 and $46, while consensus expectations called for $44.72.

Sandisk's stock was down about 5.3% in after-hours trading Wednesday after having closed down 5.4% in the regular session.

For the June quarter, Sandisk reported revenue of $8.97 billion, up 51% sequentially, and ahead of the $8.48 billion analysts tracked by FactSet had been looking for. Adjusted earnings of $39.25 per share also topped estimates for $34.96.

Sandisk CEO David Goeckeler said in a statement that the company had established its data-center business "as a key growth pillar" and deepened partnerships with customers in the fiscal year that just finished. "Our technology and products are well positioned to create value for our customers and generate growing and durable free cash flow," he added.

The company's data-center business saw revenue of $2.97 billion for the quarter, above estimates for $2.74 billion and up 103% from a year ago. Edge revenue of $5.43 billion also beat expectations for $4.46 billion. Sandisk's consumer segment recorded $556 million in revenue, far below the consensus for $874 million, and down 32% from the previous year.

Ahead of the report, Wedbush analyst Matt Bryson said he was expecting a significant beat from Sandisk given strong demand in its end markets and the company's "willingness to lead the industry in raising price to optimize" its gross margin.

Looking forward, Bryson said in a note that he sees Sandisk's earnings momentum continuing through fiscal years 2027 and 2028 as new chip capacity will be limited before the latter part of next year. Additionally, Sandisk's new multiyear customer agreements, which it introduced in April, offer more stability in pricing, he said.

In the most recent quarter, Goeckeler said Sandisk had signed five more new business model agreements with customers, including three with new customers and two expanding on agreements it has already made.

Altogether, the eight agreements have a minimum expected revenue of $93.3 billion at floor pricing, the company said.

Goeckeler said on the company's March-quarter earnings call that the agreements are "backed by firm financial commitments," and would improve the company's earnings.
