Amprius Technologies Receives Continued Listing Standard Notice from NYSE

Amprius Technologies, Inc. ("Amprius" or the "Company") (NYSE: AMPX), a leader in next-generation lithium-ion batteries with its Silicon Anode Platform, received a notice (the “Notice”) from the New York Stock Exchange (“NYSE”) on September 19, 2024 that it is not in compliance with the continued listing criteria under Section 802.01C of the NYSE Listed Company Manual (the “Listing Rule”), because the average closing price of the Company's common stock was less than $1.00 over a consecutive 30 trading-day period. The Notice is a notice of deficiency, not delisting, and does not currently affect the listing or trading of the Company’s common stock on the NYSE.

Under the Listing Rule, the Company has six months from its receipt of the non-compliance notice to cure the deficiency and regain compliance by having a closing price of at least $1.00 per share on the last trading day of any calendar month during the six-month cure period and an average closing share price of at least $1.00 over the 30 trading-day period ending on the last trading day of that month or the last trading day of the cure period.

The Company intends to remain listed on the NYSE and is considering all available options to regain compliance with the NYSE’s continued listing standards. The NYSE notice has no immediate impact on the listing of the Company’s common stock, which will continue to be listed and traded on the NYSE during such cure period, subject to the Company’s compliance with other NYSE continued listing standards.

Furthermore, the Notice is not anticipated to impact the ongoing business operations of the Company or its reporting requirements with the U.S. Securities and Exchange Commission (“SEC”).
