“Dear Fellow Indonesia Energy Shareholders:

We are pleased to share an important update in the evolution of Indonesia Energy Corporation’s corporate vision, one that reaffirms our commitment to the future of Indonesia and complements our company’s role in supporting energy, resources, and sustainable growth for this dynamic region.

Since our inception, IEC has remained committed to delivering energy security through our oil and gas exploration and production activities. While these core operations will continue to be a fundamental part of our strategy, we recognize that the definition of energy must evolve to meet the demands of a changing world, particularly in Indonesia.

The time has come for IEC to expand our vision beyond traditional hydrocarbons and embrace a broader, more sustainable portfolio. This strategic focus will position IEC to unlock new value, enhance resilience, and capitalize on emerging opportunities in sectors that are inherently interconnected with energy.

INDONESIA ENERGY: The Energy Driving Indonesia’s Future

Indonesia, the world’s fourth most populous nation, is undergoing a demographic, economic, and technological transformation. With over 280 million people, nearly 70% under the age of 45, and an economy that has grown around 5% annually, the nation is on a clear path to becoming a growing force on the world stage.

The government of Indonesia’s “Golden Indonesia 2045” vision aspires to position Indonesia among the world’s top five economies. To achieve this, the country is focusing on three fundamental pillars: energy, technology, and food security—the very elements that define human civilization and economic success.

For IEC to play an important role in this transformation, we must recognize that energy is more than just oil and gas—it is the foundation of all progress. Throughout history, economies have grown, industries have thrived, and societies have advanced by harnessing energy in its many forms. But at its core, all energy that drives life and industry can be traced back to a single source—the Sun. From oil and gas to wind, hydropower, and even the food we eat, nearly all forms of energy originate from the Sun’s immense power. Fossil fuels are simply solar energy stored in organic matter over millions of years, while bioenergy, agriculture, and even wind patterns exist because of the Sun’s influence. Hydropower is made possible by the water cycle, driven by solar radiation. In essence, the energy that sustains economies, fuels innovation, and supports communities is a continuous transformation of sunlight into different usable forms.

There are few exceptions, including deep geothermal energy, nuclear power, and tidal forces, which arise from the Earth’s internal heat, atomic forces, and the gravitational pull of the Moon and Sun. Yet, for nearly everything else, it is the Sun that provides the energy that shapes our world.

This perspective reinforces IEC’s evolving mission. We are not just an oil and gas company; we are part of the larger system that transforms energy into progress, innovation, and prosperity in Indonesia. Our role is to harness and direct this energy—where it is needed most—to power Indonesia’s future. By embracing a new definition of energy, IEC is positioning itself at the heart of Indonesia’s transformation into a global economic power. As the country continues to grow, innovate, and secure its future, IEC will be there—as the energy that enables this progress.

This is just the beginning of an exciting new chapter for IEC. Our evolving corporate vision will seek to accomplish three main goals:

Meanwhile, even as we are contemplating our expansion, this week we will be providing important updates on our key oil and gas assets, including an approximate 60% increase in proved reserves in our Kruh Block and the exciting results from a just competed geochemical survey on our potential billion-barrel equivalent Citarum Block, where we have a path to potentially move directly to drilling operations.

We remain excited about our business and the future of Indonesia, so stay tuned for more details. Thank you as always for your continued trust and support,

Sincerely,

Dr Wirawan Jusuf, Chairman & CEO

Frank Ingriselli, President

James Huang, Director and Chief Investment Officer”

Indonesia Energy Provides Update on Operations and Reserves and Planned Drilling During the Remainder of 2025

2024 investments in seismic and other work and Kruh contract extension increased reserves at Kruh Block by over 60%

JAKARTA, INDONESIA AND DANVILLE, CA, Tuesday, May 27, 2025 - Indonesia Energy Corporation (NYSE American: INDO) (“IEC”), an oil and gas exploration and production company focused on Indonesia, today provided an update on IEC’s planned drilling activity for the second half of 2025.

During 2024, IEC scaled back drilling activity at its Kruh Block asset and invested in seismic and other exploration work intended to maximize the prospects for new drilling. With that work now completed, new drilling is expected to commence at Kruh Block in the second half of 2025, as IEC plans to drill at least one new well this year as part of its multi-year program to drill 18 new wells at Kruh Block.

In its recently filed Annual Report on Form 20-F, IEC updated its proved gross reserves at Kruh Block, noting that IEC’s proved reserves increased over 60% to approximately 3.3 million barrels as a result of the additional seismic and other work conducted in 2024 and the 5-year contract extension granted in late 2023 by the Indonesian government.

Mr. Frank Ingriselli, IEC’s President, commented “We are pleased that our investments in Kruh Block and the 3D seismic work we have now completed resulted in a 60% increase in our proved gross reserves (even without any additional drilling activity). After attending meetings with the technical and operating teams in Jakarta and meetings with the drilling and operating teams in Sumatra, we are finalizing the drilling plans for later this year. With a successful result from our next well, we are hopeful that a further increase in reserves will be forthcoming. We believe our seismic data in hand will make our drilling even more effective and help us maximize the returns from this important asset”

More information regarding IEC’s planned drilling activities and reserve details for the Kruh Block and the Citarum Block can be found in IEC’s Annual Report on Form 20-F which was filed last month with the Securities and Exchange Commission and is available on IEC’s website at: https://ir.indo-energy.com/sec-filings/

Exhibit 99.3

Indonesia Energy Provides Update on Recently Completed Operations on the Citarum Block

Geochemical survey completed confirming gas and oil presence in previous discoveries which will be the target of first well to be drilled by IEC at Citarum

JAKARTA, INDONESIA AND DANVILLE, CA, Thursday, May 29, 2025 - Indonesia Energy Corporation (NYSE American: INDO) (“IEC”), an oil and gas exploration and production company focused on Indonesia, today announced encouraging results from a regional geochemical survey conducted between September 2024 and March 2025 at IEC’s 195,000 acre Citarum Block which confirms the prospectivity of the key areas of this important asset.

A detailed analysis of 135 soil samples taken from Citarum Block pursuant to an export license granted by the Indonesian government was performed by the Geochemical Exploration Services Company of Denver, Colorado. The conclusion of this detailed analysis confirmed the presence of hydrocarbons in the Pasundan-1 well, the Jatayu-1 well and the Jonggol area. IEC believes that these results significantly reduces the risk of hydrocarbon exploration and positively confirms the ultimate development and exploitation at the Citarum Block.

This valuable analysis, when combined with all the previous data that IEC has on the Citarum Block, will potentially allow IEC to bypass the need to do any more seismic work on the block and allow IEC to move directly to the drilling phase.

The Citarum Block operates under a “gross split” regime pursuant to IEC’s contract with the Indonesian government for this asset. The effect of this is that once Citarum commences production, IEC will be entitled to at least 65% of the natural gas produced. Another benefit for IEC is that the next well it drills at Citarum (which would represent IEC’s initial drilling at Citarum) will be considered an “exploitation” well, meaning IEC will have the right to produce and commercialize any oil and gas discovered from this well without delays which were previously anticipated.

Mr. Frank Ingriselli, IEC’s President, commented “We are excited about the significant results from this geochemical operation on our Citarum Block which we believe could provide a shortcut to drill our first well at this important asset and immediately begin production without the need to conduct seismic or drill an exploration well. This will move us potentially closer to realizing the value from Citarum which has prospective oil-equivalent resources of over one billion barrels.”
