Item 7.01 Regulation FD Disclosure.

On January 15, 2026, Allegro MicroSystems, Inc. (the “Company”) completed the allocation of a $285 million U.S. dollar-denominated first lien term facility maturing in October 2030 (the “Refinancing and Repricing Facility”). The applicable interest rate margin for term loans is expected to be (i) 1.75% for term loans bearing interest at a rate based on the secured overnight financing rate and (ii) 0.75% for term loans bearing interest at the base rate. The Company intends to use the proceeds of the Refinancing and Repricing Facility at closing to refinance in full the Company’s existing term loans.

The final terms of the potential refinancing and the Refinancing and Repricing Facility will be disclosed upon completion of the transaction. The foregoing transactions are subject to customary conditions and are expected to close in January 2026. However, there can be no assurance that the Company will be able to successfully complete the transaction on the terms described above, or at all.

The information in this Item 7.01 shall not be deemed “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, nor shall it be deemed to be incorporated by reference into any filing of the Company under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except as expressly set forth by specific reference in such filing.

Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Securities Act, and Section 21E of the Exchange Act. All statements, other than statements of historical facts, contained in this Current Report on Form 8-K, including statements regarding the Refinancing and Repricing Facility, are forward-looking statements. These statements involve known and unknown risks, uncertainties and other important factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements.

Without limiting the foregoing, in some cases, you can identify forward-looking statements by terms such as “aim,” “may,” “will,” “should,” “expect,” “exploring,” “plan,” “anticipate,” “could,” “intend,” “target,” “project,” “would,” “contemplate,” “believe,” “estimate,” “predict,” “potential,” “seek,” or “continue” or the negative of these terms or other similar expressions, although not all forward-looking statements contain these words. No forward-looking statement is a guarantee of future results, performance or achievements, and one should avoid placing undue reliance on such statements.

Forward-looking statements are based on our management’s current expectations, beliefs and assumptions and on information currently available to us. Such beliefs and assumptions may or may not prove to be correct. Additionally, such forward-looking statements are subject to a number of known and unknown risks, uncertainties and assumptions, and actual results may differ materially from those expressed or implied in the forward-looking statements due to various factors, including, but not limited to, those identified in Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended March 28, 2025, filed with the U.S. Securities and Exchange Commission (the “SEC”) on May 22, 2025, as any such factors may be updated from time to time in our Quarterly Reports on Form 10-Q and our other filings with the SEC. Moreover, we operate in an evolving environment. New risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties.

You should read this Current Report on Form 8-K and the documents that we reference completely and with the understanding that our actual future results may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements. All forward-looking statements speak only as of the date of this Current Report on Form 8-K, and except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements, whether as a result of any new information, future events, changed circumstances or otherwise.
