Nasdaq Notice of Failure to Comply with Continued Listing Standards

On July 2, 2026, Hongli Group Inc. (the “Company”) (Nasdaq: HLP) received a deficiency letter (the “Notice”) from the Nasdaq Listing Qualifications Department (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”). The Notice informed the Company that, based upon the closing bid price of the Company’s Class A ordinary shares (“Class A Ordinary Shares”) over the 30 consecutive business day period between May 19, 2026 and July 1, 2026, the Company is not in compliance with the requirement to maintain a minimum bid price of $1.00 per Class A Ordinary Share for continued listing on The Nasdaq Capital Market, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”).

The Notice has no immediate effect on the continued listing status of the Class A Ordinary Shares on The Nasdaq Capital Market. The Company has been provided a compliance period of 180 calendar days from the date of the Notice, or until December 29, 2026, to regain compliance pursuant to Nasdaq Listing Rule 5810(c)(3)(A). If at any time before December 29, 2026, the closing bid price of the Class A Ordinary Shares reaches or exceeds $1.00 per share for a minimum of 10 consecutive business days, the Staff will provide written notification that the Company has achieved compliance with the Minimum Bid Price Requirement, and the matter would be resolved. If the Company chooses to implement a reverse stock split, it must complete the split no later than ten business days prior to December 29, 2026, in order to regain compliance.

If the Company does not regain compliance with the Minimum Bid Price Requirement during the initial 180 calendar day period, the Company may be eligible for additional time for compliance. To qualify, the Company will be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the Minimum Bid Price Requirement, and will need to provide written notice of its intention to cure the deficiency during the second compliance period, by effecting a reverse stock split, if necessary. If the Company meets these requirements, Nasdaq will inform the Company that it has been granted an additional 180 calendar days. However, if it appears to Staff that the Company will not be able to cure the deficiency, or if the Company is otherwise not eligible, Nasdaq will provide notice that its securities will be subject to delisting.

The Company intends to actively monitor the closing bid price of the Class A Ordinary Shares and will evaluate available options to regain compliance with the Minimum Bid Price Requirement. However, there can be no assurance that the Company will regain compliance during the initial 180-day compliance period, secure a second compliance period or maintain compliance with the other Nasdaq Listing Rules.

On July 9, 2026, the Company issued a press release disclosing its receipt of the Notice, a copy of which is attached to this Form 6-K as Exhibit 99.1.
