Catalent Completes Repricing and Extension of Credit Agreement

SOMERSET, N.J., October 18, 2017 — Catalent, Inc. (“Catalent”) (NYSE: CTLT), the leading global provider of advanced delivery technologies and development solutions for drugs, biologics, and consumer health products, today announced that its wholly owned subsidiary, Catalent Pharma Solutions, Inc. (the “Catalent Operating Subsidiary”), has completed an amendment to its senior secured credit facilities to lower the interest rate on its U.S. dollar-denominated and euro-denominated term loans and its revolving loans. The new applicable rate for U.S. dollar-denominated term loans is LIBOR (subject to a floor of 1.00%) plus 2.25%, which is 0.50% lower than the previous rate, and the new applicable rate for euro-denominated term loans is LIBOR (subject to a floor of 1.00%) plus 1.75%, which is 0.75% lower than the previous rate. The new applicable rate for revolving loans is initially LIBOR plus 2.25%, which is 1.25% lower than the previous rate, and such rate can additionally be reduced to LIBOR plus 2.00% in future periods based on a measure of the Catalent Operating Subsidiary’s total leverage ratio.

The maturity date for the term loans and revolving loans was also extended by three years.

The amendment includes a prepayment premium of 1.00% in the event of another repricing event (as defined in the amendment) on or before the six-month anniversary of the amendment. There is no change to the financial covenants as a result of this repricing amendment.
