Analyst · H.C. Wainright
Thank you, Jim. Good morning, everyone. This is my third earnings call since joining Energy Focus in September of 2022, and what a ride this has been thus far. My main objective since joining the company has been to bring it back to its core of -- markets of military maritime in commercial and industrial lighting and control products, secure necessary equity capital via a strategic investment, work through significant supply chain constraints in our legacy inventory position and massive cost-cutting and rightsizing to propel the company forward into the future.
In my first call, I have stated that I was cautiously optimistic that I would be able to show progress in 6 months' time. I believe that the first quarter 2023 results that I'm sharing today are delivering on that promise to do more with less sales are beginning to rebound while operating costs have plummeted. Although I have my sight on the company's strategy aligned with much higher goals, today's results show the beginning signs of what I expect this progress towards a brighter future for EFOI.
We started the year off with a critical win in January of 2023, where we were able to secure a strategic investment from Sander Electronics. In addition to funding provided by this investment, we welcomed our new Chairman of the Board, Jay Huang, who has brought with him expertise in manufacturing, electronics industry knowledge and excitement around product development back to the organization. We are also excited to have Mr. Wen-Jeng Chang join the Board this quarter and look forward to his contributions as an experienced financial and transactional adviser.
The funding provided by the Sander investment has contributed to approximately $4.8 million in balance sheet improvements in Q1, including over $3 million in fresh capital, plus $1.7 million in debt to equity conversions. We utilized the funds to restructure our outstanding credit facilities and unsecured bridge debt to reduce borrowing costs and push out cash obligations so that our operational cash flow can be utilized for operating the business.
To recap, these improvements include a paydown of $1 million in conjunction with a restructuring of our secured inventory line through Crossroads Financial that will reduce our overall cost of this facility in 2023, a paydown of $500,000, plus exchanging another $250,000 for common stock and restructuring our payment schedule out into 2024 with our outstanding bridge note held by Streeterville Financial, and agreed termination on our accounts receivable lending facility, a conversion of primarily related party promissory notes totaling $1.5 million to common stock reducing future cash burn and additional private placements to 2 of our directors totaling an additional $955,000 during the quarter. The improvements made early in the quarter allowed us to focus on the business and set a positive tone with employees and customers to kick off the year.
Noncompliance with NASDAQ continued listing requirements, and the risk of delisting has been a looming dark cloud over EFOI for the last few quarters. Although there might not have been a direct question regarding this on the last call, I did want to speak to this today. As disclosed earlier in the month, after an appearance before a NASDAQ hearing panel in April, NASDAQ has conditionally granted our request for continued listing. The results we are sharing with you today and the balance sheet improvements I have just spoken about will satisfy the first condition of the plan we had laid out of the meeting with the NASDAQ, the continued listing requirement of a minimum of $2.5 million stockholder equity requirement.
The second condition of our continued listing compliance plan, to regain compliance with NASDAQ minimum $1 bid price requirement. As we have laid out in our proxy statement, we seek to gain stockholder approval of a reverse stock spread at the upcoming 2023 Annual Meeting of Stockholders on June 15. If you are a stockholder listening today, I encourage you to review the materials and vote yes on this proposal. We continue to believe that the liquidity offers our stockholders of remaining listed on NASDAQ is worthwhile and believes the reverse split will enable us to regain compliance with NASDAQ's requirements.
Although the sales for the first quarter continue to lag behind my long-term expectations for the business, we have shown improvement over the previous quarter with a smaller staff and no significant changes in available existing inventory as we continue to primarily sell through on-hand material, in particular, on the commercial side. Nonetheless, the existing -- the exciting piece for me is that we have continued to build a backlog of orders on both the military and commercial sides of our business in addition to generating a larger pipeline of revenues for the future.
Our customer base is anxiously awaiting the arrival of fresh stock of RedCap, our emergency backup LED tube product in addition to our power line control EnFocus switches. Both products have faced significant supply chain challenges that we have successfully navigated in Q1 and have orders placed with arrival dates we expect beginning later this quarter and continuing in future periods.
Additionally, we have been able to focus our development work on new products, including our recently announced LED mobile light tower retrofit product and our gallium nitride, or GaN, power supply products. In future periods, I look forward to making more announcements on new and exciting innovations that drive revenues with both lighting controls and energy solutions product spaces.
Innovation has been the lifeblood that has driven the EFOI success. Putting a troubled past in the rearview mirror and driving towards the success of the future is what I am determined to do. These results are only the start of the new road ahead.
Let me now review our Q1 financial results. We had net sales of $0.9 million for the first quarter of 2023, a decrease of 54.9% compared to sales of $1.2 million in the first quarter of 2022. This is driven by lower sales volumes and market adjusted pricing on the commercial side, and there was also $0.3 million of deferred military revenue recognized in Q1 of 2022.
First quarter 2023 net sales in military products were $0.6 million, which is up $0.3 million or 48% when compared to $0.3 million of sales in the fourth quarter of 2022. This reflects a renewed focus on military sales after the strategic hire made in mid-2022. Bear in mind that the sales cycle for military maritime products are dependent on many factors, including government funding, U.S. Navy award and new ship construction schedules and the timing of vessel maintenance schedules. So this quarter is really the beginning of those renewed sales efforts.
Sales of our commercial products were approximately $0.3 million or 34.5% of total net sales for the first quarter of 2023, down $813,000 as compared to first quarter of 2022. Commercial sales increased $260,000 over the prior quarter on a sequential basis. Volatility in our supply chain continued to be reflected in these results as we are primarily selling through on-hand legacy inventory while we rebuild our supply of our strongest sellers in higher-margin proprietary products like RedCap and EnFocus. However, our focus on sales execution and strategy has slowly started to improve our position in the commercial market and primed the relationships for expected inventory.
Gross profit for the first quarter of 2023 was $16,800 compared to gross loss of $25,700 in the first quarter of 2022. As a percentage of revenue, gross margin was 1.8% in the first quarter of 2023 compared to negative 1.3% in the first quarter of 2022. The year-over-year increase in gross margin was primarily driven by lower cost of sales, favorable product mix as well as the impact from prior year inventory impairment adjustments. As compared to fourth quarter of 2022, gross margin rebounded significantly from a negative margin of 35.8% dragged down in the prior quarter by low sales volume and poor product mix.
Adjusting gross profit margins for excess and obsolete, in-transit and net realizable value inventory reserve and scrap and write-offs related to our inventory reduction project contributed to the non-GAAP adjusted gross loss of 0.3% for the first quarter of 2023 compared to a gross profit margin of 5% in the first quarter of 2022. Sequentially, adjusted gross loss improved compared to an adjusted gross loss of 55.8% in the fourth quarter of 2022.
Operating expenses in the first quarter of 2023 were $1.2 million compared to $2.6 million in the first quarter of 2022. The decrease was primarily attributable to lower SG&A expenses due to significantly decreased payroll and payroll-related expenses.
Loss from operations in the first quarter of 2023 was $1.2 million, an increase over the prior year comparable quarter loss amount of $2.6 million. Loss from operations also decreased $821,000 as compared to the prior quarter.
Net loss was $1.3 million or $0.08 per share of common stock for the first quarter of 2023 as compared with a net loss of $2.8 million or $0.44 per share of common stock in the prior year comparable quarter.
Adjusted EBITDA, a non-GAAP measure, which excludes depreciation and amortization, interest expense, stock-based compensation and other nonrecurring charges and/or sources of income, such as incentive compensation, was a loss of $1.8 million for the first quarter of 2023 compared with a loss of $2.6 million in the first quarter of 2022. The improved adjusted EBITDA loss from the first quarter of 2023 was primarily due to significant cost reductions.
Now I'd like to turn to the balance sheet. Cash was $301,000 as of March 31, 2023, as compared to $52,200 as of December 31, 2022. As of March 31, 2023, the company had a total availability of $401,000, which consisted of $301,000 of cash and additional borrowing availability of $100,000 under its credit facility. This compares to total availability of $107,000 as of December 31, 2022.
As a reminder, total availability is a non-GAAP measurement of our access to cash at any given point in time, and we believe is a much more relevant metric than simply looking at cash balance or even net debt on the balance sheet. During the first quarter of 2023, we reduced the maximum availability on our inventory lending facility to $500,000 and agreed with our receivables lender to terminate our accounts receivable lending facility. Excess borrowing availability on our credit facilities represents the difference between the maximum borrowing capacity of the credit facilities and our actual borrowings under these credit facilities.
During the first quarter of 2023, cash used in operations was $1.2 million as accounts receivable grew with increased sales. Our net inventory balance of $4.9 million as of March 31, 2023, decreased from the $5.5 million balance at December 31, 2022, as we sold through on-hand inventory. Net excess and obsolete reserve adjustments during the quarter were not significant due to the levels of inventory reserve adjustments that were taken in prior periods.
With that, I will make a few closing comments. Once again, the results that were delivered today are just the beginning of a turnaround for Energy Focus. Although there is a tremendous amount of work still to be done, I believe that our biggest hurdles are behind us, and our team is focused back on sales, new product development and innovation. I look forward to sharing this journey with you next quarter.
With that, we would like to open the call to questions. Operator?
