All right. Thanks, Natalya. Good afternoon. We generated solid revenue growth and achieved profitability for 2020, despite the impacts of COVID-19 on our treatment segment. We attributed these results to the strength in our nuclear services segment and our ability to maintain field operations throughout the pandemic. I'm very proud of the fact that Perma-Fix successfully implemented our revised COVID safety plan while continuing to meet the needs of our clients during a period of time which they were largely working from their own homes. In addition, we have also improved our approach to worker safety and health programs in our plants and field operations throughout 2020, having achieved an important milestone of over 400,000 hours without an OSHA recordable incident.
This milestone is significant in our business, as the safety record reflects the focus and dedication of our team to ensure conscientious work performance and attention to detail, which directly drives productivity in the field. Turning to our results, revenue increased 43.5% over 2020. We achieved an adjusted EBITDA of approximately $5.4 million, and net income attributable to common stockholders of approximately $2.9 million for the year. This was accomplished despite significant reductions in waste receipts associated with waste generator shutdowns over the last nine months. As we enter 2021, we're continuing to realize sustainable revenue in our services segment, with waste receipts increasing, particularly in March, but will not likely get to normal levels until June timeframe due to the slowdown of waste generation activities and procurement announcements throughout the industry.
In general, Perma-Fix's performance in 2020 continues to reflect the improvements that have been made and implemented regarding our personnel and our supporting systems and technology offering and our business development organization. With total revenue for 2020 exceeding $105 million, this is the best year we've reported since 2012, which was a period in time that was enhanced by the Obama-era stimulus program. Our 2020 EBITDA performance of over $5.4 million was our best since 2011. It's also worth noting we've maintained SG&A costs at a level pace of around $11 million, which is within 10% of our three-year rolling average, demonstrating our ability to maintain our variable costs and performance in a down market. Overall, Perma-Fix is bullish on our future based on the overwhelming volume of procurements we've submitted throughout Q1 and into and through Q2 as anticipated.
Many of these procurements are directly aligned with our technologies and waste management solutions to provide us the opportunity to discriminate ourselves and remain competitive on both costing and management approaches. With hundreds of millions in bids currently submitted within the last quarter and awaiting award, we have a six-month forecast of over $100 million in procurements and task orders to be bid through our existing IDIQ and anticipated projects on the horizons that we're just waiting for RFP on. We've been developing four or five proposals simultaneously throughout Q1 and have leveraged the new technical and management talent that's joined our firm over the past few years to integrate leadership and enhance approaches to solutions both in the field and in our plants.
While all these procurements are very competitive and we don't predict the win rate, this type of action reflects a growing market and our capability to identify, position, and develop responses and proposals for these opportunities. In regards to general market conditions, Perma-Fix remains optimistic in our future growth plans based on our visibility over the next four to six quarters. This optimism is supported by our primary client, the Department of Energy in the direction we're beginning to see regarding the waste management objectives and their policies.
A few of these highlights in regards to the industry with DOE include, first, repeated statements by DOE officials that have suggested carryover funds from the government from 2020 are beginning to become evident in the DOE facilities in the form of new projects that require fast responses and innovative solutions to address some of the larger challenges within the waste management groups.
This activity has resulted in an increased number of proposals, both for nuclear services and in the waste management, waste treatment side of the house. Second, several large DOE procurements, including Oak Ridge closure and the Integrated Tank Disposition Contract, which was formerly known as the Tank Closure Contract, which have been recently published for bid, include requirements for comprehensive waste treatment solutions, as well as in-state contracting models, which support innovations and technology applications, to achieve success. In addition, these large bids with values in the billions include aggressive small business subcontracting requirements for what they call meaningful work, which is defined as project-oriented scopes of work as opposed to staff augmentation types of support. This plays well into Perma-Fix's offering to provide value-oriented solutions. We will remain a small business for the foreseeable future as well.
Third, continued progress at Hanford regarding contracting decisions and opportunities to leverage our advanced capabilities to solve large-scale waste management problems offsite. This includes our Test Bed Initiative, or TBI, which continues to offer a supplemental alternative to DOE to assist in the large waste tank disposition project at Hanford. As we've stated the past few quarters, Perma-Fix has built a very strong team of waste management and health physics professionals, along with staff that are dedicated to growth and innovation for our clients. This is evident by our most recent project, which addressed a release of radiological source within a research hospital in Seattle, where Perma-Fix provided a complete recovery and release solution back to the public and to our clients. We're expanding this experience and associated strength to other opportunities that we're currently bidding right now, have a great reference.
This foundation and the supporting reference will continue to generate opportunities in our industry, and provide unique solutions to our clients, as we pull out of this unprecedented pandemic. Completing another solid quarter while increasing revenue over 2019 and teeing up 2021 with positive momentum underscores the strength of our company and our ability to adjust our vision to meet market needs and changes. On that note, I'll turn it over to Ben, who will discuss our financial results in a little more detail. Ben?
Thank you, Mark. Beginning with revenue, our total revenue from continuing operations for the fourth quarter was $28.3 million, compared to last year's fourth quarter of $22.1 million. That's an increase of $6.2 million or 28.4%. The increase, as you said, was led by our services segment, where revenue increased by $10.8 million over the prior year, as the company continued to operate on numerous projects in both the U.S. and Canada. The increase was offset by a drop in our treatment segment revenue of $4.6 million, as waste receipts at our treatment plants continued to be impacted by the COVID-19 pandemic. For the year ended 2020, our revenue was $105.4 million, compared to $73.5 million in 2019. As with the fourth quarter, the service segment was the main driver of this increase, as revenue increased $42.2 million or 127.5%.
Despite the ongoing COVID-19 pandemic, our projects did continue to operate during most of the year, generating increased revenue, which offset the drop in our treatment segment of $10.3 million. Following a strong start to 2020, the impact of COVID-19 significantly impacted our waste receipts throughout both the second through the fourth quarters, resulting in a year-over-year drop in revenue of approximately 25%. Turning to cost of goods sold, our cost of sales was $25.2 million in the fourth quarter, compared to $17.4 million in the prior year, an increase of $7.7 million or 44.3%. This significant increase in project work in the service segment resulted in increased payroll, travel, and subcontractor expense. Headcount increased approximately 15% over the prior year, while per diem days paid increased by approximately 82%.
Conversely, the treatment segment lowered costs in transportation, disposal, and material and supplies related to processing approximately 31% less volume in the quarter. Year to date, the cost of sales was $89.5 million compared to $57.8 million in 2019, an increase of $31.7 million or 54.7%. As with the quarter, increased project work resulted in higher payroll related costs from a 22% increase in headcount, 121% increase in per diem days paid, over $15 million in subcontractor expenses, and over $4 million in materials and disposal expenses. The treatment segment processed 22% less volume, which resulted in lower transportation, disposal, and labor expenses. Our gross profit for the quarter was $3.2 million compared to $4.7 million in 2019.
The drop in gross profit of approximately $1.5 million was the result of a change in the revenue mix, as 80% of the quarter's revenue was from the service segment, compared to 53% in prior year. Project work in the services group is generally more competitive and brings lower margin than does the treatment segment. For the year ended 2020, gross profit was $15.9 million compared to $15.6 million in 2019. Despite the large increase in total revenue, the mix was 71% services work in 2020 compared to only 45% in 2019, which resulted in a small increase in gross profit, but a drop in gross margin from 21% to 15%. Our SG&A costs were $2.8 million compared to $3.3 million in the fourth quarter last year, while G&A costs for the full year were $11.8 million compared to $11.9 million in 2019.
Lower travel and trade show expenses, which occurred as a result of the COVID-19 pandemic, and bad debt expenses were down, which offset increases in payroll and health insurance benefits. Our net loss attributable to common shareholders for the quarter was $10,000 compared to last year's net income of $930. For the year ended December 31, 2020, net income attributed to common shareholders was $2.9 million compared to income of $2.3 million in the prior year. Our basic income per share for the quarter was $0.00 compared to $0.08 in prior year, and our income per share for the year ended December 31st, 2020, was $0.24 a share compared to $0.19 in the prior year. Adjusted EBITDA from continuing operations, as we defined in this morning's press release, was $709,000 compared to $1.7 million last year.
For the full year, adjusted EBITDA was $5.4 million compared to $5.2 million in 2019. Turning to the balance sheet, our cash was $7.9 million compared to $390,000 at the end of 2019. Our current accounts receivable and unbilled collectively were up $3 million, reflecting the increase in revenue primarily from the service segment. Our current liabilities were up $7.9 million, reflecting the increased operations in the service segment, timing of payments, and the current portion of our PPP loan, which was not forgiven at year-end. Our waste backlog was $7.6 million compared to $8.5 million at year-end 2019. Our long-term liabilities were up $1.3 million primarily from the inclusion of the long-term portion of the PPP loan, which is yet to be forgiven.
Our current debt, excluding debt issuance costs, was $3.6 million, with $427,000 due to our primary lender, PNC Bank, under the term loan and $3.1 million due to PNC for the PPP loan. Total debt for the year-end was $6.8 million, excluding debt issuance costs with $1.5 million due to our primary lender, PNC, for the term loan and $5.3 million for the PPP loan. Our working capital was $3.7 million compared to $26,000 at year-end 2019. Finally, I'll summarize cash flow activity. Cash provided by continuing operations was $7.9 million. Cash used by discontinued operations was $499,000. Cash used by investing activities was $1.7 million, most of which was capital spending. Proceeds provided by discontinued operations was $118,000, which was primarily for the receipt of loan payments related to the sale of our former Michigan property.
Cash provided by financing was $1.9 million, consisting of the PPP loan of $5.3 million, less our monthly term loan payments of $420,000, our net payments to the revolver of $321,000, our net payments to pay off a shareholder loan totaling $2 million, Other lease and financing payments of $800,000. With that, operator, I'll now turn the call over to questions.
At this time, if you would like to ask a question, please press star and one on your touch-tone phone. You may remove yourself from the queue at any time by pressing the pound key. Once again, that is star and one to ask a question. We will take our first question from Howard Brous. Your line is open.
Let me congratulate you on achieving $100 million in revenue, Mark, Lou, Ben, in spite of COVID and everything else. First, congratulations. Also, Ben, congratulations on your joining the board of directors of PyroGenesis. Hopefully everybody in the family is well, and everyone in the firm. Any COVID issues?
No, Howard, it's good to hear from you. No, everybody's good. We have zero COVID cases in the company right now, which you know, that wasn't the case several months ago. We are to zero. Many folks are getting vaccinated. We're hoping to stay on top of that trend.
Good. Congratulations, Mark. I'm glad to hear that. That's critically important. In your announcement today, and I just want to address one issue. I'm quoting from your announcement, "Moreover, we are rapidly advancing several initiatives within the treatment segment that we believe have the potential to significantly enhance our revenues while establishing increased market share and large backlog for waste processing." Can you be a little bit more granular in terms of that comment?
Sure, Howard. Yeah, we always have initiatives going on in each one of our plants to upgrade them and add new capabilities that would expand our inventories and our market share. We have an opportunity going on at each one of our facilities now. We have a new program in Florida, putting in what we call vacuum thermal desorption. That will significantly increase our capability to take specific kinds of waste that are coming from DOE with limited competition. That should be up and running by the end of the year at latest, more like end of Q3. That's running very well and very rapidly. We're continuing to complete our construction program at DSSI.
It's going to give us more storage capacity and allow us to expand our classified waste program, of which we have a good backlog that we have not received yet because we don't have the space that's in the classified area. We also have expansion going on at our EWOC facility, some upgrades going on with that for several procurements that we have out, we're waiting to hear on. We have some minor modifications going on up in Richland. Altogether, I think that we could see an expansion to start realizing revenue in late Q3 and Q4, but really tee up 2022 for increased waste receipts along with those access to new technologies. We're also seeing increased activity on the international front with several new waste streams being teed up for shipment in the next quarter or so.
We should start seeing some by the end of Q2 and getting some real sustainable waste streams internationally. We're excited about the waste treatment side of the house. It has taken a beating, as you know. It hasn't come back as fast as we'd hoped. We are seeing, just in the last two or three weeks, significant increasing shipments and notice of shipments and RFP activities, proposal activities that give us a lot of optimism that we could be back to normal on waste receipts by the end of Q2.
Can you define better the financial opportunities rather than the general opportunities in terms of potential revenue? Let's talk about third, fourth quarter, and importantly, 2022.
Third or fourth quarter is going to be tough to predict. Maybe $1 million or $2 million, $3 million in revenue impact into this year. We're hoping between $5 million and $10 million in additional revenue for 2022 as a base. That's along with a lot of other positive trends we're seeing on different existing capabilities, like our water system. We're starting to receive some water now. It took forever to get that whole program rolling, but it's going good now, and we're doing good on the water receipt side and processing side. Between the VTD and the classified waste and EWOC, I don't think $10 million is a big stretch to assume for 2022.
That's without any of the big opportunities that we've talked about in the past, correct?
That's correct. That's just new waste receipts. Yeah.
Right. Last but not least, but still in the same vein, you've heard nothing, because I've heard nothing on the [Navajo] issue. Have you?
We have heard nothing. Other than still moving, and we're supposed to be start seeing task orders any day kind of a thing. We have heard nothing about any task orders yet.
Again, congratulations to yourself and the team on $100 million in revenue, and that's all I have for the moment. Thank you.
All right. Thanks, Howard, appreciate it.
My pleasure.
Once again, if you'd like to ask a question, please press star and one. We will take our next question from Chuck Dickinson. Your line is open.
Dickinson, that is. Thank you for taking my question here. I wondered if you could talk in a little more detail or give a framework of how you're looking at translating or the opportunities to translate service work into additional treatment opportunities. Are we talking here about you go and you do some service work and you discover that there's treatable waste as sort of a by-product of the service you perform that happened to come about? Is it alternatively a situation where the customers say, DOE or whoever is, let's say they're so satisfied with the service work that you perform, and if it's done reliably, that then they come back to you and say, "By the way, we also have some treatment work we'd like to give to you as well." How do you see that translation unfolding from service into waste treatment opportunities?
Chuck, we do have several bids, or several jobs I should say, that have included extensive nuclear services work in the field, that have resulted in shipment of waste to ourselves to process. The job up in Harborview hospital, for example, we did the remediation, packaged the waste, shipped it to our facility in Richland, Washington, processed it and got rid of everything. We were full service, cut out a lot of inefficiencies. It worked really well. Other projects, we'll typically do the remediation and the waste may or may not require treatment. In other words, if it doesn't require treatment, it can be shipped directly for disposal in a landfill. That's normally the large volume of the waste we have, that's the case. We're bidding on several jobs right now that does include some treatment and some processing.
If there's any way we can ship something like large components to our facilities and do the dismantlement offsite, we will do that. It doesn't always afford that opportunity. To answer your question, most of the time it's one or the other. We're either doing the waste treatment or we're doing the services. In the field, if you're doing the services, the nuclear services types of jobs, you're typically shipping the waste direct to disposal, and it doesn't have the opportunity for the treatment overall. What we do is, where the real discriminator comes in for our company, is we have the waste management people, the professionals, the engineers, that we put on the services projects that are able to manage the waste and minimize the treatment that's necessary and optimize the packaging so that you can go directly to disposal and save money.
Okay, great. The only other question I had was, do you have a sense of what percent of your workforce that's in the field that has been vaccinated already for COVID-19? Is that the key item to look at, or is it more you have to look at vaccination across all of your client base as well? Maybe all this is academic come the end of May or June, as you say things are expected to start ramping up then. Maybe it's not a question that's really that important, but just kind of a curiosity as to what percentage is already vaccinated.
Chuck, I'd be just guessing, since we have not polled. We do plan on polling at some point just to see what percentage we're talking about, but we have not done that yet. In East Tennessee here, where we have about a third of the company, it's running around at 20% as a population. I have no idea where our folks are. I do know in my office here, it's much higher than that, and we have about 40 folks in our office, in the administrative side of the house. As far as the plants go, I'd just be guessing. I have no idea, I'm afraid.
Okay. The waste receipts that you're starting to see trend up, although not back to a normalized level, but starting to trend up a little bit in this month, that may have some correlation, I would guess, to people being vaccinated.
That's correct. I would assume that as well.
Okay. Thank you.
Thanks.
It appears we have no further questions at this time.
All right. I'd like to thank everyone for participating on our fourth quarter conference call. As I mentioned earlier, we remain bullish on the outlook for the full year. We appreciate the continued support of our shareholders and look forward to providing further updates as developments unfold. Thank you.
This does conclude today's program. Thank you for your participation. You may disconnect.
