Item 7.01. Regulation FD Disclosure.

On May 18, 2026, representatives of the Company will make a presentation to investors using slides containing the information attached to this Current Report on Form 8-K as Exhibit 99.1 (the “Investor Presentation”) and incorporated herein by reference.

The Investor Presentation includes financial information not prepared in accordance with generally accepted accounting principles (“Non-GAAP Financial Measures”). A reconciliation of the Non-GAAP Financial Measures to financial information prepared in accordance with generally accepted accounting principles (“GAAP”), as required by Regulation G, is included within Exhibit 99.1 to this Current Report on Form 8-K. The Company is providing disclosure of the reconciliation of reported Non-GAAP Financial Measures used in the Investor Presentation, among other places, to its comparable financial measures on a GAAP basis. The Company believes that the Non-GAAP Financial Measures provide investors additional ways to view our operations, when considered with both our GAAP results and the reconciliation to net income and net cash provided by operating activities, which we believe provide a more complete understanding of our business than could be obtained absent this disclosure. We believe the Non-GAAP Financial Measures also provide investors a useful tool to assess shareholder value.

By filing this Current Report on Form 8-K and furnishing the information contained herein, the Company makes no admission as to the materiality of any information in this report that is required to be disclosed solely by reason of Regulation FD.

The information contained in the Investor Presentation is summary information that is intended to be considered in the context of the Company's Securities and Exchange Commission (“SEC”) filings and other public announcements that the Company may make, by press release or otherwise, from time to time. The Company undertakes no duty or obligation to publicly update or revise the information contained in this report, although it may do so from time to time as its management believes is warranted. Any such updating may be made through the filing of other reports or documents with the SEC, through press releases or through other public disclosure.

The information presented in Item 7.01 of this Current Report on Form 8-K and Exhibit 99.1 shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, unless the Company specifically states that the information is to be considered “filed” under the Exchange Act or specifically incorporates it by reference into a filing under the Securities Act of 1933, as amended, or the Exchange Act.

Forward-Looking Statements This presentation includes "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995 and other applicable federal securities laws. All statements that are not historical facts are forward-looking statements. Forward looking statements can be identified through the use of words such as "estimate," "project," "intend," "expect," "believe," "should," "anticipate," "hope," "optimistic," "plan," "outlook," "should," "could," "may" and similar expressions. The forward-looking statements are subject to certain risks and uncertainties, including without limitation those identified below, which could cause actual results to differ materially from historical results or those anticipated. Readers are cautioned not to place undue reliance on these forward-looking statements. The following factors could cause actual results to differ materially from historical results or those anticipated: adverse economic conditions, including risks relating to the impact and spread of and the government’s response to pandemics; inability to weather an economic downturn; the impact of competitive products and pricing; product demand and acceptance risks; raw material and other increased costs, including the impact of tariffs; raw material availability; financial stability of the Company’s customers; customer delays or difficulties in the production of products; loss of consumer or investor confidence; employee relations; ability to maintain workforce by hiring trained employees; labor efficiencies; risks associated with acquisitions; environmental issues; negative or unexpected results from tax law changes; inability to comply with covenants and ratios required by the Company’s debt financing arrangements; and other risks detailed from time-to-time in Ascent Industries Co.'s Securities and Exchange Commission filings, including our Annual Report on Form 10-K, which filings are available from the SEC. Ascent Industries Co. assumes no obligation to update any forward-looking information included in this release. Non-GAAP Financial Information Financial statement information included in this earnings release includes non-GAAP (Generally Accepted Accounting Principles) measures and should be read along with the accompanying tables which provide a reconciliation of non-GAAP measures to GAAP measures. Adjusted EBITDA is a non-GAAP financial measure that the Company believes is useful to investors in evaluating its results to determine the value of a company. An item is excluded in the measure if its periodic value is inconsistent and sufficiently material that not identifying the item would render period comparability less meaningful to the reader or if including the item provides a clearer representation of normalized periodic earnings. The Company excludes in Adjusted EBITDA two categories of items: 1) Base EBITDA components, including: interest expense, income taxes, depreciation and amortization, and 2) Material transaction costs including: goodwill impairment, asset impairment, gain on lease modification, stock-based compensation, non-cash lease cost, acquisition costs and other fees, shelf registration costs, loss on extinguishment of debt, retention costs and restructuring & severance costs from net income. Management believes that these non-GAAP measures are useful because they are key measures used by our management team to evaluate our operating performance, generate future operating plans and make strategic decisions as well as allow readers to compare the financial results between periods. Non-GAAP measures should not be considered as an alternative to any measure of performance or financial condition as promulgated under GAAP, and investors should consider the Company's performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial condition of the Company. Non-GAAP measures have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for analysis of the Company's results or financial condition as reported under GAAP.
