ENVX Tumbles After Hours On Smartphone Battery Qualification Timeline Concerns

• Talluri acknowledged that the qualification process has taken longer than expected.
• He further noted encouraging results in energy density, fast charging, and safety, with longer-term cycle-life testing still ongoing.
• The company provided second-quarter guidance of $8.0 million to $9.0 million in revenue and adjusted net loss per share of $0.13 to $0.17.

Shares of Enovix Corporation (ENVX) fell 12% after hours on Wednesday, as investors appeared disappointed by the firm’s smartphone battery qualification timelines despite first-quarter earnings beating Wall Street expectations.

The silicon battery cell maker’s CEO Raj Talluri said smartphones remain the company’s top priority as it works to finish qualification with its lead customer and prepare for commercial production in the demanding consumer electronics market.

The company has reached a key milestone by agreeing with its lead smartphone customer on a new testing framework designed specifically for its silicon batteries. Talluri added that the second smartphone customer also agrees that the old industry testing standard is not suitable for silicon technology, and the two sides are discussing a replacement framework.

Talluri acknowledged that the qualification process has taken longer than expected. He further noted encouraging results in energy density, fast charging, and safety, with longer-term cycle-life testing still ongoing. Beyond smartphones, the company’s defense business continues to show strong commercial momentum, and its battery for smart eyewear has entered early production, Talluri said.

ENVX Q1 Earnings

On Wednesday, Enovix reported first-quarter 2026 revenue of $7.6 million, a 49% increase from $5.1 million in the year-ago period, driven by higher shipments in defense and industrial markets.

Looking Ahead

The company provided second-quarter guidance of $8.0 million to $9.0 million in revenue, in line with an expected $8.57 million, and adjusted net loss per share of $0.13 to $0.17, lower than the loss of $0.20 expected by Wall Street. Capital expenditures are expected to range between $9.0 million and $13.0 million, the firm said.
