Chris,

the floor is yours.

Thank you, Chris. Good afternoon, everyone, and thank you for joining us today. 374 Water is an industrial technology and services company focused on transforming the waste management landscape. Our proprietary air flow system offers a groundbreaking solution for the destruction of solid and liquid organic waste, both non-hazardous and hazardous, across municipal, federal, and industrial sectors. Our technology not only eliminates waste but also generates safe, dischargeable water, mineral byproducts, bent gas, and recoverable thermal energy. We are targeting $450 billion waste destruction and management market that is increasingly demanding sustainable next generation solutions. Our air flow system is uniquely positioned to meet this need, offering a scalable, modular, and customizable platform that can replace or augment conventional, often inefficient, waste management approaches. We've built a flexible commercial model that includes waste destruction as a service, capital sales, and leases, allowing us to address diverse customer needs and to drive adoption across market segments. With a growing backlog and revised sales pipeline, our goal is to convert opportunities into revenue for the coming months. Based on our current trajectory, discussions with potential partners, and market demand, we believe we are on a path towards achieving $250 to $500 million in annual revenue in five years. As a reminder, our mission is to help create and preserve a clean and healthy environment to sustain life. Moving on to our operational highlights and business updates for 2025 year to date, I would like to discuss some of the team's accomplishments this year, building on the foundational steps we took in 2024 to position the company for long-term success. In Q1, we continue to ruggedize and optimize our AS system, upgrading our pre- and post-treatment systems, and further refining and expanding our destruction capabilities across solid and liquid waste. We made great progress in Orlando with the initial phase of our deployment focused on demonstrating the effectiveness of our air flow system, destroyed AFFF firefighting foam, granular activated carbon, and ion exchange resins. The test results achieved north of 99.99%, PFAS elimination across these waste streams, reinforcing the efficacy of our solution, further supporting our launching of waste destruction services. Supercritical water oxidation technology has also gained further validation, having been named by the EPA as an emerging PFAS destruction technology. We also secured a waste destruction services contract with the University of North Carolina at Chapel Hill Collaboratory to destroy AFFF firefighting foam on behalf of the state. If we are awarded additional materials, this multi-phase contract could be worth north of five million in future revenues to our company. And we also continue to advance partner negotiations with RCRA Part B treatment, storage, and disposal facility operators to establish regional waste destruction service operations across North America. During Q2, we signed a waste destruction services term sheet with Crystal Clean, a leading provider of specialized environmental and waste management solutions to commercial and industrial end markets, to conduct operations at their RCRA Part B DSDS facility in Ohio. We also shifted our focus to our 90-day biosolids destruction campaign in Orlando, which unlocks meaningful revenue. Our main focus here has been improving run duration and system reliability, particularly on components outside of the reactive. All improvements identified are being made to the AS units slated to be shipped to OC-SAN, which is in line with our mutual agreement. While we still plan to begin mobilizing equipment to OC-SAN in June, full system installation is likely to be delayed by a few months to complete further upgrades to the AS system and as OC-SAN secures requisite permits. Finally, we will be deploying an AS-6 unit to Detroit, Michigan in partnership with Arcadis for a DOD demonstration. We believe these activities have actively de-risked our business and placed us on the path to achieving material waste destruction service revenue in the future. To support our growth, we've also strengthened our leadership team and board of directors. We welcomed Raj Malkhote as chief technology officer whose global engineering expertise will be instrumental in driving continuous product innovation and commercialization. Raj has already hit the ground running and he is having a materially positive impact. Steve Jones, former CEO of Cavanta, has joined our board of directors. His strong background in leadership positions in environmental services, corporate governance, and commercial strategy are valuable assets to the company. Additionally, we appointed James Polowski as an advisor and he has also been appointed for election as a director at our annual meeting. Mr. Polowski brings extensive executive experience from Veolia, North America, and environmental services, as well as DuPont, which will be invaluable to our company growth. We believe our technology has the potential to deliver scalable commercial grade waste destruction solutions which would set us apart in a fragmented and outstated waste treatment industry. Our product roadmap includes four distinct air school models, each designed to address a range of customer requirements with varying needs. These include our ultra-mobile AS1, the mobile AS6, the semi-permanent AS30, and our high capacity customizable AS100 plus, which will be designed for large-scale site specific deployments. Currently, we are close to completing the manufacturing of our AS1 and AS6 units to meet existing contracts and scheduled demonstrations. In parallel, we are designing our AS30 for potential production beginning this year, and we are progressing long sales cycle high value opportunities for our AS100 plus units with municipal customers. We believe we're at a pivotal inflection point in the commercialization of our business. We are tracking multiple near-term opportunities for AS capital sales and leases, as well as other waste destruction service opportunities in 2025. We look forward to sharing material updates on these opportunities as we advance them throughout the year. Let me now provide a high-level overview of our current and near-term operational footprint. Today, we operate facilities in Florida and North Carolina. In the near term, we are preparing to deploy air school systems to four key locations. Orange County Sanitation District in California, Queen Earth in Detroit, Michigan for the DIU-DOD initiative focused on commercial-scale PFAS destruction solutions for military and federal installations, Peterson Space Base in Colorado. Finally, we have signed a non-binding term sheet to establish our first waste destruction service operations at Crystal Clean's Ohio TSDF facility. Our waste destruction services term sheet with Crystal Clean is based on a revenue sharing and system hosting model. When the full agreement is finalized, Crystal Clean will not only host our air school system at the ERIKRA Part B TSDF in Oregon, Ohio, but also provide waste hauling, processing, storage, and other services. In addition, the term sheet contemplates that we will jointly and individually market waste destruction services to municipal, federal, and industrial customers. We are very excited to work with Crystal Clean in the near future. We were also selected to participate in a highly anticipated Department of Defense initiative focused on commercial-scale PFAS solutions for military and federal installations, and will be mobilizing to Detroit shortly. As previously noted, we have already demonstrated the effectiveness and adaptability of our air school technology for federal agencies on the majority of the waste stream we will be processing in Detroit. We believe our system is poised to provide a permanent solution for federal agencies here. In addition, the government has indicated the Detroit DIU demonstration should unlock the federal government and military's golden ticket, enabling them to directly contract with Arcadis and 374 Water without going through lengthy competitive bid processes. As you can imagine, we are quite excited about the potential here. Further, in March, we secured a contract with the state of North Carolina to destroy AFFF under the state's Responsible Firefighting Foam Management Act. We are proud to be supporting this important initiative through a partnership with the University of North Carolina at Chapel Hill Collaboratory, one of the most ambitious state-led PFAS destruction efforts to date. The initial phase of the program targets the treatment of 1,000 gallons of AFFF with a phase expansion plan that could scale to as much as 29,000 gallons. This effort positions 374 Water as a leader in PFAS remediation and sets the stage for future large-scale environmental cleanup projects. Let's now turn to our -to-market strategy and commercial momentum. Our approach is intentionally diversified and focused on well-established end markets that require advanced waste destruction solutions like our AirSquo system. We offer customers multiple procurement options to meet varying operational and budgetary needs, including capital purchases, leases, and waste destruction services. We're seeing strong interest from municipal officials, many of whom are eager to begin waste destruction operations and are evaluating both capital purchase, lease, and waste destruction service models. On the federal side, the U.S. government has made significant commitments to the removal and destruction of PFAS and other canada nets from military and civilian facilities. With hundreds of millions of dollars already appropriated for this effort, we believe 374 Water is well positioned to compete for and secure a meaningful share of this work. We also continue to ramp up efforts to capture industrial waste destruction opportunities, which we see as a significant and growing revenue stream. Most recently, the U.S. EPA announced new major actions to combat PFAS contamination, underscoring the federal government's commitment to safeguard public health, preventing PFAS from entering drinking water systems, and holding polluters responsible. We believe the EPA's stance on PFAS provides positive tailwinds for our Air Squill platform. We are also advancing strategic partnership discussions with multiple other TSDS to establish on-site waste destruction services operations. In addition to our Krista Terms Sheet, our internal goal is to finalize one or more additional TSDS definitive agreements yet this year. Our team continues to actively pursue and expand these commercial channels, and we look forward to updating you on our progress in the quarters ahead. We've discussed the clear and growing market demand for our Air Squill waste destruction technology. As we look ahead, we believe we are entering a pivotal phase for scaling our technology and the business. Again, our growth strategy is driven by a mix of capital equipment sales, leases, and waste destruction services. We intend to capture this growth through strategic partnerships, continued market development, and geographic expansion across our core municipal, federal, and industrial verticals with an initial focus on the U.S. market. Looking to the remainder of 2025, we have line of sight to generate $4-6 million in revenue. Based on current and anticipated future demand, we believe we are on a credible path to achieving -$500 million in annual revenue in five years. With that, I'll now turn the call over to Russ McQuine, our Chief Financial Officer, to walk through our financial results for the first quarter of 2025.

Thank you, Chris. For the three months ended March 31, 2025, the company generated revenue of $543,000 compared to $315,000 in the prior year quarter. The company's business has been focused on the development and commercialization of our air-sclosed systems. Revenue is primarily attributable to equipment manufacturing services, demonstrations, and from treatability study services. During the first quarter, we completed a full-scale demonstration for a customer resulting in an increase in our services revenue of $376,000 offset by a decrease in equipment manufacturing revenue of approximately $162,000. Total operating expenses increased 106% to $3.9 million for the three months ended March 31, 2025, compared to $1.9 million in the prior year quarter. The increase was primarily due to an increase in professional fees of $0.5 million, an increase of $0.9 million in general and administrative expenses, and an increase in compensation and related expenses of $0.6 million. The increase in our professional fees are primarily non-recurring expenses related to the settlement of a legal matter and recruiting fees related to the increase in headcount. The increases in general and administrative expenses and compensation expenses stem from increased stock-based compensation, continued efforts to establish our executive team, as well as the relocation of our manufacturing facility and continued commercialization and growth efforts. Net loss for the three months ended March 31, 2025, was $3.7 million as compared with $2.0 million in the prior year quarter. Cash and cash equivalents as of March 31, 2025, was $6.9 million as compared to $10.7 million as of December 31, 2024. As of March 31, 2025, working capital was $8.7 million compared to $11.7 million as of March 31, 2024. Based upon our current cash position, we project to have adequate cash to support our 2025 business plans. We are reviewing capital opportunities and are in active discussions with possible strategic partners to support our business growth. I will now hand the call back to Chris for his comments.

Thank you, Russell. As we look ahead to the remainder of 2025, we are building on the solid groundwork laid in 2024 to transition 374Water into a high-growth company generating material revenue. Our mission is clear to provide scalable, effective waste destruction solutions for markets that urgently need them. The demand for advanced environmental technologies is accelerating, and we believe 374Water is uniquely positioned for leadership in this sector. Our air-screw technology directly addresses a critical global challenge, which is the safe, scalable destruction of waste streams. We are targeting large, underserved markets, namely municipal, federal, and industrial, where traditional waste destruction solutions are no longer sufficient. Our strategy to create a national network of TSBS facilities is sound and will enable us to unlock material contracts. Regulatory momentum, particularly around PFAS and other contaminants, is creating tailwinds that reinforce the need for our solution. Our system is scalable and customizable, enabling us to serve a wide range of customers and waste profiles. Our commercial model is flexible, with options for waste destruction services, capital sales, and leases, providing multiple revenue streams, and we believe we have a growing pipeline of real waste destruction services, capital sale, and lease opportunities to support our near and long-term revenue targets. Taken together, we believe these pillars position us for strong, sustainable growth. We are executing against a clear roadmap, expanding our team, and strategically deploying capital. We believe 2025 will be a breakout year as we move towards growth and long-term market leadership. We continue to see the potential to drive meaningful environmental impact while disrupting industries, and we are energized by the opportunities ahead and grateful for your continued support. With that, I'd like to thank everyone for joining us today. I will now hand the call over to the operator to begin our question and answer session. Operator, please go ahead.

Thank you. To ask a question, you may press star, then one. If you're using a speakerphone, please pick up your handset before pressing the keys. To remove yourself from the queue, you may press star, then two. At this time, we will pause momentarily to assemble our

call.

Please go ahead.

Good afternoon, gentlemen, and congratulations on all the milestones in the quarter. The Crystal Clean deal really caught my eye. You mentioned you expect one more perhaps in balance of the year. Do you have a forecast for what a typical destruction as a service deal would generate in revenue?

Hey, Michael, thanks so much for being on the call and for the question. I'll let Russell address the economics. To put a finer point on the TSDF side, we are in discussions with multiple different TSDF players across the United States and in advanced discussions there. The goal ultimately is to set up regional facilities to cover the entire United States. Those are the ongoing conversations. Crystal Clean, a wonderful organization. They have additional RCRA TSDF facilities coming online shortly as well. Again, there's a lot of work going on in that realm right now and we're very excited about it. To the economics, Russell, could you address that?

Thank you, Chris and Michael, thank you for the question. The revenue potential will of course depend on the type of material being processed and the size of the AirSquare unit. We expect to initially start with an AirSquare 6 and then our plans would be going forward to increase that capacity with our AirSquare 30 unit. On the AirSquare 30, we project that the revenue potential for that unit will be between $12 and $20 million on an annual basis depending upon the type of material being processed and the related utilization. That's what we're excited about this opportunity to launch and continue to grow our waste destruction service business.

Thank you, that's a big number. Looking at other high leverage opportunities, when do you think the Department of Defense demo was expected to wrap up?

That's a several month process. We'll be mobilizing there shortly, starting to mobilize in June, be on site in July, and then we have a number of months to complete those demonstrations. I think what's important there is that we've already done all of those demonstrations for the military, for the federal government. This is hopefully the last step in that process to again secure that opportunity to bid directly on very large scale contracts. The other gating item for us there was having a RCRA permitted site, TSDF facility, and we are solving that issue as well. I think we are collectively very excited about the future there and doing more for the government, for the military.

Great, and if I could just wrap up with one last question. The aqueous foam destruction for North Carolina, when would that be expected to start and finish?

We're actually in the process of arranging to pick up the initial 1,000 gallons of that and we will be starting within the next month or so on that work.

Terrific. Thanks again and congrats on the quarter.

Thank

you.

Thank you. As a reminder, to ask a question, you may press star spin one on your telephone keypad.

I'm seeing no further questions at

this time. I would now like to turn the call back over to Mr. Gannon for his closing remarks.

Great, thanks so much operator. I'd like once again to thank everyone for joining our conference call today and we look forward to continuing to update you on our go forward progress and growth. If you have any additional questions, please reach out to MZ group as an initial step. That concludes our first quarter 2025 update call. Thank you everybody and I look forward to talking to you again very shortly.

The conference is now concluded. Thank you for your participation. You may now disconnect your lines.
