Allegion Completes Extension and

Increase of Revolving Credit Facility

DUBLIN (May 20, 2024) – Allegion plc (NYSE: ALLE), a leading global security products and solutions provider, has successfully completed the extension and increase of its existing senior unsecured revolving credit facility.

The new $750 million five-year credit facility is unsecured and has investment grade terms similar to the $500 million facility it replaces. It provides Allegion with commitments for revolving loans – a portion of which may be used for letters of credit and swingline loans. The company’s term loan facility, which had $221.9 million outstanding as of March 31, 2024, remains substantially unchanged and continues to mature on November 18, 2026.

“The new revolving credit facility supports Allegion’s already strong liquidity position and is consistent with the size of our business,” said Mike Wagnes, Allegion senior vice president and chief financial officer.

The new revolving facility, including the letters of credit and swingline loans, may be incurred in U.S. Dollars, Euros and Pounds Sterling. Commitments under the new revolving facility will terminate on May 20, 2029.
