Letter to Stockholders

Dear Stockholders,

We are pleased to invite you to the 2026 Annual Meeting of Stockholders of Ranger Energy Services, Inc. (the “Annual Meeting”), which will be held virtually on May 15, 2026, at 10:00 a.m. Central Daylight Time. The Company has elected to hold the Annual Meeting in a virtual format to facilitate convenient and accessible participation by its stockholders.

2025 Performance Highlights

2025 was a year of meaningful progress for Ranger Energy Services. Against the backdrop of a dynamic operating environment, we delivered strong financial results, advanced our strategic priorities, expanded market leadership, and returned significant capital to stockholders while maintaining the balance sheet strength and financial discipline that supports our long‑term strategy.

Key Achievements:

•Financial Performance: We delivered another strong year of performance with full year revenue of $546.9 million, full year net income of $12.3 million, Adjusted EBITDA 1 of $73.2 million, Net Cash from Operating Activities of $69.0 million, and Free Cash Flow 1 of $42.9 million.

•Market Leadership: We acquired American Wells Services in November 2025, making us the largest well-services provider in the Lower 48. This transaction expands our customer relationships with blue‑chip operators and adds high‑margin complementary service lines, including tubing rentals and inspection, chemicals, and mixing plant services.

•Innovation and Technology: We delivered the industry’s first ECHO hybrid electric rigs, which are engineered to operate with zero emissions when connected to well‑site power. These rigs incorporate electric drivetrains, regenerative braking and battery recharging, modular architecture, and real‑time diagnostics that are integrated with our proprietary digital platforms.

•Capital Returns: We returned over 40% of 2025 Free Cash Flow to investors through dividends and share repurchases, far exceeding our minimum commitment of 25%.

•Safety: We continue to invest in our TANGO operations platform, Human Performance training and our Overwatch AI‑enabled safety system, which enhance operational visibility, efficiency, and safety performance across our fleet.

Looking Ahead

Ranger enters 2026 with a stronger platform, expanded capabilities, and a clear strategic roadmap. Our production‑focused portfolio, disciplined financial approach, and continued investment in technology and safety position us well to generate durable cash flows and attractive returns across commodity cycles. We remain focused on executing our strategy with discipline and integrity, always with the objective of creating long‑term value for our stockholders.

On behalf of the Board of Directors and the entire Ranger Energy Services team, thank you for your continued confidence and support.

Sincerely,

Stuart N. Bodden

President and Chief Executive Officer

Ranger Energy Services, Inc.
