Item 8.01 Other Events.

As previously disclosed, on August 2, 2026, Integer Holdings Corporation, a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement,” and the transactions contemplated thereby, the “Transaction”), by and among the Company, Armstrong Parent, Inc., a Delaware corporation (“Parent”), and Armstrong Bidco, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”). Pursuant to the Merger Agreement, and upon the terms and subject to the conditions therein, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent. Parent and Merger Sub are each affiliates of investment funds managed by Kohlberg Kravis Roberts & Co. L.P., a leading global investment firm.

On September 30, 2026, the Company issued a press release announcing that it had received early termination of the waiting period with respect to the consummation of the Merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”). The receipt of early termination of the waiting period under the HSR Act with respect to the consummation of the merger satisfies one of the conditions to the closing of the transactions contemplated by the Merger Agreement, which remains subject to other customary closing conditions, including approvals under certain other applicable antitrust and foreign direct investment laws. The Merger is expected to close by the end of calendar year 2026. A copy of the release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The special meeting of the Company’s stockholders to approve the Merger is scheduled for October 21, 2026, beginning at 9:00 a.m. Central Time. The board of directors of the Company unanimously recommends that stockholders of the Company vote “FOR” the merger agreement proposal and “FOR” each of the other proposals described in the Definitive Proxy Statement, filed with the SEC on September 14, 2026.

Cautionary Statement Regarding Forward-Looking Statements

Some of the statements contained in this communication and other written and oral statements made from time to time by us and our representatives are not statements of historical or current fact. As such, they are “forward-looking statements” within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act, and are subject to the safe harbor created thereby under the Private Securities Litigation Reform Act of 1995. We have based these forward-looking statements on our current expectations, and these statements are subject to known and unknown risks, uncertainties and assumptions. Forward-looking statements include, but are not limited to, statements relating to: our goals, plans, and strategic initiatives; long-term growth prospects; maximizing value for our stockholders; and other events, conditions or developments that will or may occur in the future; and timing of any of the foregoing. You can identify forward-looking statements by terminology such as “may,” “will,” “should,” “could,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “projects,” “forecast,” “outlook,” “assume,” “potential” or “continue” or variations or the negative counterparts of these terms or other comparable terminology. These statements are only predictions and are no guarantee of future performance, and investors should not place undue reliance on forward-looking statements as predictive of future results. Actual events or results may differ materially from those stated or implied by these forward-looking statements. In evaluating these statements and our prospects, you should carefully consider the factors set forth below. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by these cautionary factors and to others contained throughout this communication.

Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements regarding the transactions contemplated by the Agreement and Plan of Merger, by and among the Company, Parent and Merger Sub. All such forward-looking statements are based upon current plans, estimates, expectations, opportunities and ambitions that are subject to risks, uncertainties, assumptions, and other important factors, many of which are beyond the control of the Company, that could cause actual results to differ materially from those expressed in such forward-looking statements. Key factors that could cause actual results to differ materially include, but are not limited to, the expected timing and likelihood of completion of the Transaction, including the timing, receipt and terms and conditions of any required governmental and regulatory approvals; the occurrence of any event, change or other circumstances that could give rise to the termination of the Transaction; the possibility that the Company’s stockholders may not approve the Transaction; the risk that the parties may not be able to satisfy the conditions to the Transaction in a timely manner or at all; risks related to disruption of management time from ongoing business operations due to the Transaction; the risk that any announcements relating

to the Transaction could have adverse effects on the market price of the Company’s common stock; the risk that the Transaction and its announcement could have an adverse effect on the parties’ business relationships and business generally, including the ability of the Company to retain customers and retain and hire key personnel and maintain relationships with their suppliers and customers, and on their operating results and businesses generally; the risk of unforeseen or unknown liabilities; customer, stockholder, regulatory and other stakeholder approvals and support; the risk of unexpected future capital expenditures; the risk of potential litigation relating to the Transaction that could be instituted against the Company or its directors and/or officers; the risk associated with third-party contracts containing material consent, anti-assignment, transfer or other provisions that may be related to the Transaction which are not waived or otherwise satisfactorily resolved; significant costs, or expenses incurred in connection with the Transaction; Parent’s ability to obtain the necessary financing arrangements set forth in the commitment letters received in connection with the Transaction; certain restrictions contained in the Agreement and Plan of Merger that may impact the Company’s ability to pursue certain business opportunities or strategic transactions; the risk of various events that could disrupt operations, including pandemics, epidemics or other public health crises or severe weather (such as droughts, floods, avalanches and earthquakes), cybersecurity attacks, security threats and governmental response to them, and technological changes; the risks of labor disputes, changes in labor costs and labor difficulties; and the risks resulting from other effects of industry, market, economic, legal or legislative, political or regulatory conditions outside of the Company’s control. All such factors are difficult to predict and are beyond our control, including those detailed in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2025, which was filed with the SEC on February 23, 2026, the Company’s quarterly report on Form 10-Q for the fiscal quarter ended July 3, 2026, which was filed with the SEC on August 4, 2026 and other documents subsequently filed by the Company with the SEC. The Company’s forward-looking statements are based on assumptions that the Company believes to be reasonable but that may not prove to be accurate. Other unpredictable factors not discussed in this communication could also have material adverse effects on forward-looking statements. The Company does not assume an obligation to update any forward-looking statements, except as required by applicable law. These forward-looking statements speak only as of the date hereof.
