On April 30, 2025, Nine Energy Service, Inc. (the “Company”) received written notification (the “Price Criteria Notice”) from the New York Stock Exchange (the “NYSE”) that the Company is not in compliance with Section 802.01C of the NYSE Listed Company Manual because the average closing share price of the Company’s common stock, par value $0.01 per share (the “Common Stock”), was less than $1.00 over a consecutive 30 trading-day period.

The Company plans to notify the NYSE within the required timeframe that it intends to cure the stock price deficiency and regain compliance. Under the NYSE’s rules, the Company can regain compliance at any time within the six-month period following receipt of the Price Criteria Notice if on the last trading day of any calendar month during the six-month cure period the Common Stock has a closing share price of at least $1.00 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.

The Company intends to consider all available options to cure the deficiency and regain compliance, including, but not limited to, a reverse stock split, subject to stockholder approval no later than at the Company’s next annual meeting of stockholders, if necessary to cure the stock price non-compliance. Under the NYSE’s rules, if the Company determines that it will cure the stock price deficiency by taking an action that will require stockholder approval, the Company must obtain the stockholder approval by no later than its next annual meeting of stockholders and implement the action promptly thereafter, and the price condition will be deemed cured if the price promptly exceeds $1.00 per share and the price remains above that level for at least the following 30 trading days.

The Price Criteria Notice is separate from the previously disclosed notice of noncompliance that the Company received from the NYSE on October 21, 2024 due to the Company’s average global market capitalization falling below $50,000,000 over a trailing consecutive 30 trading-day period while its stockholders’ equity was less than $50,000,000. In accordance with applicable NYSE procedures, the Company developed and submitted a plan to the NYSE demonstrating how it intends to regain compliance with the market capitalization and stockholders’ equity continued listing standard within 18 months of the Company’s receipt of such notice, which was reviewed and accepted by the Listings Operations Committee of the NYSE. If the Company does not regain compliance with such continued listing standard by April 21, 2026, or does not make progress consistent with such plan, the NYSE may initiate proceedings to delist the Common Stock. The NYSE may also commence accelerated delisting action if the Common Stock trades at an “abnormally low” price or if the Company’s average market capitalization falls below $15 million over a 30 trading-day period.

A delisting of the Common Stock from the NYSE could negatively impact the Company as it would likely reduce the liquidity and market price of the Common Stock and thus (i) reduce the number of investors willing to hold or acquire the Common Stock, which would negatively impact the Company’s ability to raise equity financing, and (ii) impair the Company’s ability to provide equity incentives to its employees.

The Price Criteria Notice has no immediate impact on the listing of the Common Stock, which will continue to be listed and traded on the NYSE during this period, subject to the Company’s compliance with the other listing requirements of the NYSE. The Common Stock will continue to trade under the symbol “NINE” with an added designation of “.BC” to indicate that the Company currently is not in compliance with the NYSE’s continued listing requirements. The “.BC” indicator will be removed if and when the Company regains compliance with the NYSE’s continued listing standards. If the Company is unable to regain compliance, the NYSE will initiate procedures to suspend and delist the Common Stock.

The foregoing contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Exhibit 99.1

Nine Energy Service, Inc. Receives Notice from NYSE Regarding

Continued Listing Requirements

HOUSTON – Nine Energy Service, Inc. (“Nine” or the “Company”) (NYSE: NINE) announced today that, on April 30, 2025, the Company was notified by the New York Stock Exchange (“NYSE”) of its noncompliance with Section 802.01C of the NYSE Listed Company Manual because the average closing price of its common stock had fallen below $1.00 per share over a period of 30 consecutive trading days.

Under the NYSE’s rules, the Company can regain compliance with the minimum share price requirement at any time within the six-month period following receipt of the NYSE notification if on the last trading day of any calendar month during the six-month cure period, the Company’s common stock has (i) a closing price of at least $1.00 per share and (ii) an average closing price of at least $1.00 per share over the 30 trading-day period ending on the last trading day of such month.

The Company’s Board of Directors is reviewing all available alternatives to regain compliance with the NYSE’s minimum share price requirement, including, but not limited to, a reverse stock split, subject to stockholder approval no later than at the Company’s next annual meeting of stockholders, if necessary to cure the stock price non-compliance. Under the NYSE’s rules, if the Company determines that it will cure the stock price deficiency by taking an action that will require stockholder approval, the Company must obtain the stockholder approval by no later than its next annual meeting of stockholders and implement the action promptly thereafter, and the price condition will be deemed cured if the price promptly exceeds $1.00 per share and the price remains above that level for at least the following 30 trading days.

During the cure period, subject to the Company’s compliance with other NYSE continued listing requirements, shares of the Company’s common stock will continue to be traded on the NYSE under the symbol “NINE” with an added designation of “.BC” to indicate that the Company currently is not in compliance with the NYSE’s continued listing requirements. If the Company is unable to regain compliance, the NYSE will initiate procedures to suspend and delist the Company’s common stock.

The NYSE notification does not affect the Company’s business operations or its Securities and Exchange Commission reporting requirements and does not result in a default under any of the Company’s material debt agreements.
