Regulation FD Disclosure (Form 8-K)

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.
