Thank you, Joe. Good morning, everyone. We're pleased to have you join us on this call, and your continued support is greatly valued. Before we delve into the numbers, I would like to highlight that I'm pleased with our quarterly results and the positive momentum we are building. The market is sending clear signals. Our customers are looking for more assets that protect marine environments, collect essential ocean data, and enhance national security. We are converting our pipeline of opportunities into backlog and revenues, as seen with recent wins like the NOAA IDIQ. We believe we are well-positioned to translate this momentum into profitable growth and value for our shareholders. Let's talk about some recent developments.
On September 1, 2023, we secured 3 significant 3-year Indefinite Delivery, Indefinite Quantity contracts, with a total contract value expected to be in the $ millions from the National Oceanic and Atmospheric Administration. These projects emphasize our commitment to marine conservation and research. In August, we celebrated the opening of our marine robotics production facility in Richmond, California. This event showcased our dedication to innovation, particularly in autonomous vehicles and wave energy buoys, supporting America's energy, independence, and national security. In August, we achieved a milestone by demonstrating the Wave Adaptive Modular Vehicle attaching itself remotely to a buoy. This accomplishment showcases our advanced autonomous capabilities and opens doors to various maritime applications. During the quarter, we continued our work with the U.S. government agency, supporting autonomous vehicle demonstrations for a range of services.
We also continued our work with the Department of Energy, related to the full-scale operations of the MOSWEC System . We are enthusiastic about future partnerships, reinforcing our commitment to both the commercial and security sectors. Our opportunity pipeline continues to grow. In addition to putting down $several million from this into purchase orders, we've also continued to add to the top of the pipeline, with it currently sitting above $78 million, for a net gain exceeding $11 million in just the first few months of the fiscal year. We're continuing to grow our revenues and our gross profit margins are increasing. Our strategy is working, and we see additional opportunity for multi-system orders on the horizon. Now, before we dive into the financial highlights, I would like to introduce our CFO, Bob Powers.
Bob will provide you with more detailed information about our financial performance in Q1 fiscal 2024.
Thanks, Philipp. Let's begin with revenue. In Q1 2024, our revenues reached $1.3 million, marking a significant increase compared to the $700,000 reported in Q1 2023. This was our highest quarterly revenue figure in over 7 years and continues the traction gain during fiscal 2023. This growth can be attributed to our strong performance in WAM-V sales, revenue generated from our DOE contract, and the delivery of our strategic consulting services. Our gross profit for Q1 2024 stood at $700,000, a substantial improvement compared to the Q1 2023 figure, which showed a gross profit of $200,000. This improvement is primarily attributed to our unmanned vehicles business, particularly the higher-margin WAM-V leasing business and our strategic consulting services.
I am enthused about the progress we've made in this area and the expansion of the progress made in fiscal 2023. Our operating expenses for Q1 2024 amounted to $8.1 million, reflecting our investment in both personnel and systems to support the growth Philipp and I discussed previously. As for our net result, we reported a net loss of $7 million for Q1 2024, compared to a net loss of $5.9 million for Q1 2023. We continue to manage our costs tightly, making targeted investments in the personnel and structure needed to support our strategy and plans for growth. On the balance sheet front, our combined cash, unrestricted cash, cash equivalents, and short-term investments as of July 31, 2023, totaled $26.7 million.
Notably, we continue to maintain a debt-free balance sheet with no bank debt in our financial structure. In terms of cash flow, the net cash used in operating activities for Q1 2024 amounted to $8 million. This primarily reflects our net loss and the payout of employment bonuses accrued during fiscal year 2023. In addition, our autonomous vehicles business continues to exceed our expectations, resulting in the payment of the earn-out accrued during fiscal 2023. Finally, you will note that our inventory balance increased by approximately $700,000 to $1.7 million. This investment in inventory was necessary in order to satisfy growing backlog, as well as our planned growth in revenue for fiscal 2024. That covers our financial update.
Before we enter Q&A, I'd like to remind everyone that the purpose of today's call is to discuss our Q1 of fiscal 2024, 2024 results, as well as our financial outlook. As we head into the Q&A, we ask that you limit your questions to these topics. Thank you.

Well, thank you. Good morning, everyone. Hey, Phil, could you expand a little bit on those NOAA contracts? I'm trying to understand the nature of them. Sounds like they came through very quickly. I don't know if they're in the backlog or not, but how does this affect two things? One, are there going to be renewable recurring revenue, I should say, from these? And two, what are the implications for other applications with NOAA? I mean, is this like a pilot or something that would have long legs to it or is this more of a one-off type of purchase?
Sean, thanks for dialing in, and thank you for the question. Yeah, the NOAA contracts are what the government refers to as IDIQs, Indefinite Delivery, Indefinite Quantity. These are three-year contracts that have a ceiling attached to them, and in the non-governmental commercial world, you essentially can consider them very similar to master services agreements with a ceiling that have call-off orders attached to them. There's an agreed rate sheet that we've got in place with NOAA. We've been awarded three of these. So these are specifically for vehicles that are provided on leases with day rates and operators. And the way we framed the statement, I think is entirely accurate. These aren't for demonstrations.
This is for NOAA to use these vehicles within a specific line office to do specific jobs, be that around, you know, weather observations, be that around, you know, sea monitoring, or be that around illegal fisheries activities. It is part of the U.S. government's continued effort to increase the number of unmanned and uncrewed surface vehicles that are in operations around the United States. So we're very excited about these, because these are true commercial contracts with commercial terms that give us some clarity over real opportunities over the next three years to provide vehicles on a call-off basis.
It's kind of the OPT's first big commercial contract, right? If I'm understanding this correctly, deployment and operations for 2 years, this is not the pilot, this is a real application. And is that the first one we've had just like this, that's kind of reaching an inflection point, or have you had similar types before?
So I think certainly from a, you know, NOAA perspective and from our vehicle perspective, this is the first time that our vehicles have been under long-term commercial call-off contracts with the government. In governmental terms, these sort of fall under what the government would term COCO, Contractor-Owned Contractor-Operated type offerings. So yeah, we're very excited about this because on the basis of this, it enables us to expand the offering, provide our vehicles into additional parts of the U.S. government and monetize the lease fleet on day rates.
Great. Thank you. I'll step back in queue.
Thank you. We've reached the end of our question and answer session. I'd like to turn the floor back over to management for any further closing comments.
Thank you for your participation and for being shareholders and stakeholders in OPT. We never take any of you for granted, and we continue to work towards value enhancement for all of our shareholders and all of our employees. Thank you.
Thank you. That does conclude today's teleconference and webcast. You may disconnect your line at this time and have a wonderful day. We thank you for your participation today.
