REVOLVING CREDIT FACILITY

HOUSTON - March 5, 2025 - VAALCO Energy, Inc. (NYSE: EGY; LSE: EGY) ("Vaalco" or the "Company") announced that it has entered into a new revolving credit facility ("the new facility") with an initial commitment of $190 million and the ability to grow to $300 million, led by The Standard Bank of South Africa Limited, Isle of Man Branch with other participating banks and financial partners.  This new facility, which is subject to customary administrative conditional precedents, replaces the Company's existing undrawn revolving credit facility that was provided by Glencore Energy UK Ltd.  The Company arranged the new facility primarily to provide short-term funding that may be needed from time-to-time to supplement its internally generated cash flow and cash balance as it executes its planned investment programs across its diversified asset base over the next few years.

Key terms include:

•     Six-year term with facility amortization to begin on September 30, 2026;

•     Initial commitment of $190 million with the ability to grow to $300 million through a $110 million accordion;

•     Amounts drawn bear interest of 6.5% plus SOFR until the Côte d'Ivoire Floating Production Storage and Offloading vessel ("FPSO") Dry Dock Refurbishment Project is completed;

•     Interest rate will decrease to 6.0% plus SOFR once the FPSO project is completed;

•     Undrawn available amounts incur a fee of 35% of margin per annum and undrawn unavailable amounts incur a fee of 20% of margin per annum, with semi-annual borrowing base redeterminations; and

•     Secured with Vaalco's Gabon, Egypt and Côte d'Ivoire assets.

"Closing this new credit facility will supplement our internally generated cash flow and cash balance to assist in funding our robust organic growth projects," said George Maxwell, Vaalco's Chief Executive Officer. "With $190 million in initial commitment and the ability to grow to $300 million, this facility enables us to fund any short-term capital funding needs that may occur as we execute the significant growth projects across our assets over the next couple of years. We appreciate the support shown by our lending group which we believe affirms the strength of our diverse asset base. We are excited about the major projects that we have planned which are expected to deliver a step-change in organic growth across our portfolio."

The Company entered into the new facility with The Standard Bank of South Africa Limited, Isle of Man Branch as the lead bank on the facility. Other participants include Rand Merchant Bank, The Mauritius Commercial Bank Limited and Glencore Energy UK Ltd.
