This afternoon, you will hear from Blue Bird's President and CEO, Phil Horlock, and CFO, Jeff Taylor. We will take some questions. Let's get started. Phil?
Thanks, Mark. Well, good afternoon, thank you all for joining us today for our fourth quarter and full year earnings call for fiscal 2020. Before I jump into our financial results, I'd like to give an assessment of how I see our business environment today, particularly, the outlook for the school bus industry. Let's turn to slide four. Not surprisingly, the fourth quarter was a challenging one as we entered our second quarter of dealing with the COVID-19 pandemic. As you'll see, we continue to improve our business structure. While significant, the impact of the pandemic on our fourth quarter results was less severe than we experienced in the third quarter, we are seeing positive signs that the industry recovery is on the horizon. Nonetheless, we had to deal with some significant challenges.
About 50% of schools chose online teaching over classroom teaching, and a significant portion of the balance elected a hybrid program alternating between online and classroom teaching. This approach was deployed throughout the fourth quarter and was largely in place at the start of the new school year. One fact is clear and obvious. When schools are closed, buses aren't being ordered. The good news is that when schools are open, it's business as usual with school bus orders being placed. With uncertainty over in-classroom teaching, our new order intake in support of school start was slow, and this was seen in our unit sales for this quarter, which were down 23% from a year ago. This was a significant sales decline, it was considerably lower than the 43% reduction we saw in the third quarter.
In fact, fourth quarter sales were nearly 50% higher than what we achieved in the third quarter. The pace of decline was significantly lower than we saw in the third quarter as school districts began to deal with the pandemic and refocused on their school bus needs. On the supply chain front, while we did experience some late parts and shortages, this did not cause interruption of production, and overall material supply was significantly better and more consistent than in the prior quarter. The outcome of all these factors is a full year industry estimate of 28,500 school buses, reflecting new vehicle registrations compiled by R. L. Polk. That's a 17% decline from fiscal 2019, and more than a 30% decline in the second half of the year.
We are seeing some positive trends and news that indicate an industry recovery and profitability rebound that should be ahead of us later in fiscal 2021 in support of 2022 school start. From a Blue Bird performance standpoint, there are several factors worth noting. Since suspending production for two weeks in April, we have had uninterrupted production with a rigorous deployment of COVID-19 safety measures throughout the company and a significantly improved supply chain. We successfully moved to a single shift in June, restructuring our workforce and support teams and are seeing efficiency and quality gains, particularly evident in the first quarter of fiscal 2021. Turning to the three-pronged margin improvement strategy that I've covered in detail in prior earnings calls, despite the lower industry, we increased our average bus selling price over fiscal 2019 by 7% in both the fourth quarter and the full year.
That's a significant increase and a strong endorsement of our products. It was another very strong year in alternative fuels, with 53% mix of sales in the fourth quarter and a 48% mix for the full year, equaling last year's record. Finally, our third focus, lowering structural costs through our transformational initiatives, delivered almost $15 million of savings in the full year. Despite the severe volume impact of COVID-19, we've continued to improve our business structure, ensuring we are well-positioned for when the industry rebounds. Now on the external front, President-elect Biden has declared school opening as one of three key 100-day deliverables being targeted by the new administration. Together with the rollout of the COVID-19 vaccines, we have increased optimism about the industry outlook.
Finally, we have been seeing increased quote activity in recent weeks, and our first quarter fiscal 2021 production slots are all filled. All these factors suggest that we should see an industry recovery as we move through the second half of fiscal 2021, particularly in support of 2022 school year. Let's now turn to slide five and cover the fourth quarter and full year financial highlights. Our fourth quarter financial results were significantly impacted by COVID-19, although we still made a solid profit. At about 2,900 buses, our unit sales were down 850 units from last year, representing a decline of 23%. This compares favorably, however, with the 43% decline that we saw in the third quarter. Similarly, net sales of $281 million for the quarter were 18% below last year.
The lower decline in net sales revenue than in unit sales reflects the 7% increase in average bus selling price that I mentioned earlier. This result is a really positive aspect of our fourth quarter performance and a cornerstone of our margin growth strategy that's clearly working. Adjusted EBITDA of $21.9 million was $11.5 million below the same period last year, fully explained by the lower unit sales of 850 buses. Turning to the full year, I'm pleased to say that our financial results were either better than guidance or at the high end of the guidance range that we provided to you at the last earnings call. We sold just under 8,900 school buses in fiscal 2020, representing a 19% reduction from last year. Incidentally, prior to the COVID-19 impact, we were on track to sell at least 11,000 buses this year.
Net sales of $879 million and adjusted EBITDA of about $55 million were both above guidance, although $140 million and $27 million below last year, respectively. Adjusted free cash flow for the year was slightly negative and at the high end of the guidance range. Now, on the previous slide, I covered the operational improvements we continue to make to improve business structure and drive ongoing margin growth, namely higher prices, increased mix of alternative fuels, and lower structural costs. We also continue to drive efficiencies and quality improvements through our move to a single shift in the summer, and we'll be expanding our single shift capacity in early 2021. I'll cover that more in detail later.
We consistently have strong liquidity, and at $180 million at the end of the fourth quarter, we can handle a difficult environment in which we are operating today, and we continue to drive cash improvements in the first quarter of fiscal 2021. Finally, as announced last week, as many companies have done, we successfully amended our loan agreement with our banks, providing covenant relief over the next six quarters. This provides us with the financial flexibility to operate our business during this unprecedented pandemic while preserving future growth opportunities. Overall, despite very tough business conditions, I am really pleased with our focus and our progress this year. Now let's go to slide six and review our major operating achievements in fiscal 2020. First is the safety and well-being of our employees.
We've taken significant measures to protect our employees from COVID-19 and have established a rigid protocol that has served us well to date. Needless to say, a safe and healthy workforce is key to our business continuity, and we have an incredibly loyal and dedicated team of professionals. Second is annual pricing to recover economics and the introduction of new products and features. With a 7% increase in average bus selling price in the last year, which includes pure pricing, a richer vehicle mix, and higher option take, we are confident in our annual pricing capability. Third is a relentless focus on driving down structural costs through our transformational cost initiatives, which delivered nearly $50 million in savings in fiscal 2020, and more than $50 million in savings since we started three years ago.
We also supplemented this program with targeted reductions in SG&A, specifically in the area of organizational structure. Fourth, our continued growth in the mix of alternative fuel-powered school buses, where we benefit from higher margins and increased owner loyalty compared with conventional fuels. Our leadership position across all of these fuel types, but particularly in propane, where we achieved a 76% market share, and electric at 59% share, indicates that our strategy is working, and we look forward to continued strong growth in this area. The rapidly growing interest for electric buses is a really exciting opportunity for us and should generate significant growth in the years ahead. Now, pursuing these priorities is fundamental to achieving our EBITDA margin target of at least 10% in the near term, and we're setting the foundation to achieve this target despite the unprecedented impact of COVID-19 today.
It's timely to take a closer look at our alternative fuel bus sales performance on slide seven, and we also have an exciting new product announcement to make in this space. Despite the slowdown in bus orders, our mix of alternative fuel-powered buses remains as strong as ever at 48% of our unit sales in fiscal 2020. This was a record mix for Blue Bird, tying last year's result. It's all the more impressive when it's achieved during a pandemic that's impacting an entire industry. Our North American market share in alternative fuels was 58% for the full fiscal year. As a measure of our strength in this area, let me give you some details. We were number one in propane with 76% market share. We were number one in electric, growing from 15% market share last year to 59% in fiscal 2020.
Importantly, our electric bus share in the U.S. was a substantial 77%. We were number 1 in compressed natural gas bus sales with 50% market share. Now, that's leadership across the board. Significantly, 309 customers purchased new types of alternative fuel buses from us for the first time in 2020. That's on top of more than 400 customers who tried our alternative fuel options last year for the first time. Importantly, these alternative fuel choices have enabled us to conquest new business from our competitors, bringing in 157 new customers to the Blue Bird family this year. These are compelling facts, and with the higher customer loyalty we enjoy from these products, it's a great endorsement of our exclusive alternative fuel buses, the Blue Bird brand, and our dealer network.
We sold and delivered 158 electric-powered school buses, compared with 56 last year, and are off to a great start in fiscal 2021, with more than 80 orders in our backlog. We're not new at this electric business. We're not a startup that's achieved only a handful of deliveries. We've been building and delivering zero-emission school buses for over two years now, and announced only this quarter that we'd expanded our electric bus capacity sixfold to 1,000 buses a year in anticipation of meeting the growing demand. We have the broadest EV range in the industry, with Type A, Type C, and Type D offerings on the road today. We're number 1 in market share this year and are preparing to deliver our 300th electrical school bus in the coming weeks.
We're very excited about our EV growth opportunities going forward, and we'll keep you posted on our progress. Looking ahead, the vast majority of the Volkswagen mitigation funding is still ahead of us, too, and will help us to boost sales over the next three years or so with many states earmarking specific funds for school bus purchases. We've had really good results so far with our propane electric buses from this program based on the funds that have been issued. The recently announced $100 million Bezos Earth Fund grant to the World Resources Institute also provides a boost with its unique carve-out for zero-emission school buses. In summary, I'm very proud of our strong and undisputed leadership in alternative fuels. We have the best partners, we have the best products, and they're exclusive to Blue Bird.
With less than 20% of school districts having purchased an alternative fuel-powered school bus today, we have plenty of runway ahead for continued growth. As we look ahead, where do we see this segment going for Blue Bird? As the right-hand box shows, you can see how far we've come in the last four years, from a 26% mix of Blue Bird sales to a 48% mix this year. That's outstanding growth any way you look at it. Looking ahead, we don't see this growth stopping. In fact, we project that four years from now, between 60%-70% of all Blue Bird buses sold will be powered by a fuel that's an alternative to diesel. That's an increase of up to 3,000 alternative fuel-powered buses over this year.
We are bullish about this growth opportunity, and we're investing in the business, and we see electric and propane power as the way forward in alternative segment. We have some really exciting news to tell you. We're bringing yet another alternative fuel engine to the school bus market. Let's turn to slide eight. I'm pleased to announce for the first time in public that we will be launching a brand-new propane and gasoline engine in the Blue Bird Vision. After nine amazing years of growth using our 6.8 L propane and gasoline engine that have defined alternative fuels in the school bus industry, we are replacing it with an all-new 7.3 L eight-cylinder engine. This engine was introduced by Ford in its F-series lineup just over a year ago, and already has tens of millions of miles of experience on the road. It's class-leading and a winner.
Now, working with our partners at Ford and Roush, we've been developing a school bus application for this engine over the past two years, and we'll be launching the new product in early 2021. Once again, it's a unique offering by Blue Bird, thanks to an exclusive three-way partnership that's now approaching 10 years. The new engine brings a lot of great attributes, best horsepower and torque in the industry, improved fuel economy, better quality and ease of service, and a smaller dimensional package, so it's easy to work on in the engine compartment. As the tagline says, "The best just got better," and will be open for orders in the next few days. This is just another example of our commitment to best-in-class alternative fuel products, focusing on zero emissions and low-NOx engines. We have much more to come in this space. Stay tuned.
I'll now turn it over to our CFO, Jeff Taylor, who'll take you through the financial results in more detail. I'll be back later to cover our outlook and fiscal 2021 guidance. Over to you, Jeff.
Thanks, Phil, and good afternoon. It's my pleasure to share with you the financial highlights from Blue Bird's fourth quarter and full year 2020. The quarter and year-end are based on a close date of October 3rd, 2020, whereas the prior year was based on a September 28th, 2019, close date. We are filing the 10-K tomorrow, December 17th, which includes additional material and disclosures regarding our business and financial performance. We encourage you to read the 10-K and the important disclosures that it contains. The appendix attached in today's presentation reconciles differences between GAAP and non-GAAP measures mentioned on this call, as well as important disclaimers already mentioned by Mark. With that, please refer to slide 10, and I will review the key results for the fourth quarter. Overall, it was a strong quarter for Blue Bird, especially considering the challenging operating environment due to the global pandemic.
Let me say first and foremost, our number one priority was and will continue to be protecting the health and safety of our employees. While operating conditions were tough, they improved significantly over the third quarter as supply shortages and disruptions lessened in the fourth quarter, and we maintained production without any unplanned plant shutdowns. Furthermore, as we discussed on our third quarter earnings call, we implemented additional cost control measures in the fourth quarter with the goal of protecting the balance sheet and liquidity while preserving the ability to recover quickly when schools reopen and school bus demand returns to pre-pandemic levels. Fourth quarter volume of 2,876 units was down 23% compared to the prior year period, on lower industry volumes due to the COVID-19 pandemic. It increased 48% sequentially as expected and consistent with our guidance.
Net revenue of $281 million was $62 million or 18% lower year-over-year for the quarter. Bus net revenue of $269 million was down $57 million on lower volume. Bus average selling price or ASP was $93,400 per unit, a year-over-year increase of $5,900 per unit due to pricing increases to offset inflationary cost pressures and favorable product mix, including strong growth in electric buses. Parts revenue for the quarter was $12.9 million, representing a decrease of $4.9 million as a portion of maintenance facilities were shut down due to the virus. Parts revenue increased sequentially by $4.3 million or 50%. Gross margin was 10.5%, about 310 basis points lower than the prior year period. The decline in margin in the fourth quarter was almost entirely the result of lower efficiency due to lower volume and higher costs associated with COVID-19.
Selling, general, and administrative or SG&A was $16.1 million, which was down $12.1 million on reduced spending and cost control actions in our management and engineering areas. As discussed last quarter, we are targeting $15 million of annualized cost reductions, and we are delivering on that commitment. GAAP net income of $11.9 million in the fourth quarter was $0.3 million higher than the prior year period. On an adjusted basis, net income was $13.3 million, down $6.7 million versus last year. Adjusted EBITDA of $21.9 million was strong, but down by $11.5 million compared to the prior year quarter, which I will cover in more detail on the next slide. The operations group executed very well to deliver this solid fourth quarter result. Our adjusted EBITDA margin was 8%, a decrease of approximately 190 basis points.
Diluted earnings per share of $0.44 was $0.01 better than the prior year, consistent with our GAAP net income, as our number of diluted shares outstanding was essentially unchanged. Weighted average diluted shares were 27 million during the fourth quarter versus 26.9 million in the same period last year. Fourth quarter adjusted diluted earnings per share at $0.49 were $0.25 lower than the prior year, consistent with adjusted net income. Liquidity was approximately $180 million on October 3rd, as our revolver was fully paid down from the third quarter. Note that quarter-end liquidity was prior to the third amendment on our credit agreement, which I'll cover momentarily. Looking at the fourth quarter adjusted EBITDA bridge, year-over-year bridge on slide 11.
Starting on the left of the chart, lower bus volume of 850 units, partially offset by mix and lower freight and warranty expense, decreased adjusted EBITDA by $11.6 million. Pricing and transformational initiatives such as strategic sourcing added $8 million. Lastly, higher manufacturing costs due to lower efficiency and COVID-specific costs, partially offset by lower SG&A expense, lowered adjusted EBITDA by $7.9 million, resulting in the quarter of $21.9 million. Sequentially, adjusted EBITDA was up by $9.4 million on higher unit volume of 928, higher manufacturing efficiencies from running a single shift operation, and cost control initiatives which impacted the quarter. Slide 12 is a summary of our full year 2020 results. Overall, the 2020 year was a tale of two halves. The first half of the year started exceptionally strong with financial results higher year-over-year.
The second half of the year was negatively impacted by school closures and lower school bus demand resulting from the COVID pandemic. Full year net revenue of $879 million was down $140 million or 13.7%. Bus net revenue of $823 million was down $130 million, driven by lower volume of 2,139 units. Bus net revenue per unit, however, was $92,700, which represented a $6,200 per unit increase from the prior year due to price increases to offset inflationary cost pressures and favorable product mix, including a strong year-over-year growth in electric buses, as Phil mentioned. Parts revenue for the year was $57 million, representing a decrease of $10 million, as some maintenance facilities were shut down either partially or entirely during 2022 due to schools not operating a normal schedule. Full year gross margin of 10.9%, about 220 basis points lower than the prior year.
The deterioration in margin in 2020 was almost entirely the result of two items. First, one-time launch costs incurred in the first half of fiscal 2020. Second, and more notably, the impact of inefficiencies on our plant caused by COVID-related items. COVID impact included a three-week unplanned shutdown, lost absorption from lower volume, supplier disruptions, higher labor costs from overtime and absenteeism, and additional costs related to employee safety that we took in response to COVID. GAAP net income of $12 million in fiscal 2020 was $12 million lower than the prior year. Adjusted net income of $22.1 million was lower by $21.3 million year-over-year, largely due to lower gross profit for the year. Adjusted EBITDA of $55 million was down by $27 million compared to the prior year, which I will cover in more detail on the next slide.
The EBITDA margin was 6.2%, a decrease of 180 basis points. Diluted EPS of $0.45 was $0.45 lower than the prior year, consistent with the year-over-year decline in net income. In full year, adjusted diluted EPS at $0.82 was $0.79 below the prior year, once again, consistent with the year-over-year decline in adjusted net income. Weighted average diluted shares were 27.1 million versus 27 million last year. Slide 13 shows the year-over-year change in adjusted EBITDA from 2019 to 2020. Starting on the left of the chart, lower volume of 2,139 units, partially offset by favorable mix and lower freight and warranty expense decreased adjusted EBITDA by $24.9 million. Pricing and transformational initiatives combined added $20.1 million.
Lastly, higher manufacturing costs were driven by impacts from COVID on operating leverage and efficiency, as well as launch costs partially offset by lower SG&A expense, decreased adjusted EBITDA by $22.3 million, resulting in the full year of $54.7 million. Moving on to free cash flow, slide 14. This table shows both fourth quarter and full year free cash flow in addition to adjusted free cash flow. The fourth quarter is normally a seasonally strong quarter for free cash flow due to the lowering of working capital, and 2020 was no exception. I am very pleased to report that fourth quarter adjusted free cash flow was $81.3 million, driven by a $68 million reduction in working capital, largely inventory.
While free cash flow was $79.6 million, as I mentioned on the third quarter call, we launched a cash conservation initiative to capture $40 million of cash by year-end, and we were successful. For the full year, adjusted free cash flow was just below break even at -$0.9 million, and free cash flow was -$15.5 million. While our overall free cash flow for the year was negative, I am very pleased with the actions we took to minimize our cash use in 2020. Looking at net debt leverage and liquidity, net debt of $129.6 million was $17.4 million higher versus the prior year due to less cash on the balance sheet.
Our net leverage ratio for the fourth quarter and year-end was 3.1 x, which was still meaningfully below the net leverage ratio covenant of less than 3.7 times in our credit agreement prior to the third amendment we announced on December 9th. With our business entering the seasonally slow period and the COVID-19 pandemic expected to persist into 2021, we felt it was prudent to seek covenant relief for our fiscal 2021 and the first half of 2022. During the relief period in fiscal 2021, the net leverage covenant is removed and replaced with a trailing 12-month EBITDA test measured quarterly and a liquidity test measured monthly. In fiscal 2022, the net leverage ratio covenant is reinstituted at four times during the first two quarters.
Also, our revolver availability is limited to $100 million during the relief period, along with other conditions, which are described in the 8-K that we filed on December 9th. Liquidity was $179.5 million at year-end, and we have fully paid down the revolver balance since the end of the third quarter. Since completing the credit agreement amendment, the revolver has remained unutilized and our liquidity has remained strong. We are continuing our cost control initiatives to further protect our cash and liquidity into the foreseeable future. In conclusion, the fourth quarter was a strong finish to a tough year. The company acted quickly and decisively to contain costs when the pandemic hit, and the results of our actions are evident.
We adjusted our operations to a single shift, lowering our manufacturing cost, and flexed up inventory early to protect our production plans, but flexed down later when supply stabilized in order to recover the working capital. We amended our credit agreement to provide flexibility with the covenant structure and protect liquidity. We continue to execute our margin growth strategy. Finally, there are positive trends regarding a COVID vaccine, which should allow schools to reopen for a fall 2021 school start, if not sooner. While the first half of 2021 will still be impacted by COVID, we are optimistic that the recovery will begin sometime in the second half. I will now turn the discussion back to Phil Horlock, who will describe the outlook for 2021 and give his closing remarks.
Thanks, Jeff. Let me now summarize the outlook that we see for both our operating performance and the school bus industry, which are the basis for our fiscal 2021 guidance. Turning to slide 17. Our focus at Blue Bird is on delivering superior operating performance. We can't change the industry outcome this year, but we can focus on improving every element of our business so that we are well-positioned when the industry rebounds, as it inevitably will, so that we also rebound. That means executing our margin growth strategy by improving bus selling price, alternative fuel mix, and cost structure. An example of a structural change that drives superior operating performance was our move to a single shift production schedule in June. We know we build a bus more efficiently and with better quality when all of our team is working together on the same single shift.
It's proven and a fact. The next step for us was to break specific plant bottlenecks, which we started during our October shutdown and will complete in our December holiday shutdown. From early 2021, we will be able to build as many units on one shift that we used to build on two shifts in straight time. That's a smart move. Turning to the external environment, there are a number of factors that will influence the industry outlook, the most important being the return to in-classroom teaching. We know that when children are in the classroom, school buses are needed to transport children safely, and we see orders for new buses. The positive recent developments in COVID-19 vaccine distribution and President-elect Biden's 100-day goal to open schools should impact the school bus industry favorably.
Additionally, with 25% of the 600,000-unit North American school bus fleet being 15 years or older, and aging more when schools are closed, there is great demand for new buses from school districts. It's not a question of if the industry rebounds, but a question of when. We expect to see improvements later in fiscal 2021 in support of the new school start. The most recent external forecast by ACT is for an industry of 29,000 buses in fiscal 2021, similar to fiscal 2020. Now, this can be significantly influenced by the external initiatives that I just covered. Now, with so much uncertainty and speculation on when schools will fully resume in-classroom teaching, we believe it prudent to provide a wide guidance range and to be prepared for a surge in orders should the industry recover faster. Our guidance range is shown on slide 18.
This slide shows the key metrics for which we provide guidance. For net sales revenue, we are forecasting a range of between $750 and $975 million. Adjusted EBITDA, between $40 and $65 million. Adjusted free cash flow between $5 million negative and $20 million positive. Our guidance reflects industry assumptions ranging from 26,000- 30,000 buses, with the lower end assuming COVID-19 causes increased disruption to classroom teaching and minimal industry recovery in the second half of fiscal 2021. The higher industry outlook of 30,000 units reflects resumption of in-classroom teaching later in fiscal 2021 and an increase in orders in support of 2022 school start. As the heading says, we believe it's important to plan prudently and somewhat conservatively while aggressively pursuing operational improvements. We will narrow guidance as the control of the pandemic becomes clearer.
I'd now like to share our thoughts with you on when we expect to be back on track to achieve our declared goal of at least a 10% EBITDA margin in the near term. Turning to slide 19. This slide illustrates the adjusted EBITDA impact of COVID-19 on fiscal 2020 results and on the 2021 forecast. We were on track to achieve our original guidance fiscal 2020 until the pandemic hit in the third quarter. As Jeff told you earlier, we had a great first half for fiscal 2020. We were hit with some bad news in the second half, caused entirely by COVID. While we do expect some industry recovery in the second half of fiscal 2021, we expect a significant industry rebound toward pre-COVID levels in fiscal 2022, commencing with school start.
As volume recovers, we expect to resume our glide path towards at least a 10% adjusted EBITDA margin in the fiscal 2022 and 2023 timeframe. Despite the COVID challenges and its impact on today's school bus industry, we haven't lost sight of our mission, to grow profitability and increase EBITDA margin to at least 10% in the near term. To this end, we'll continue to drive improvements across all elements of our business, thereby improving our underlying margins, and we're reporting our progress each quarter. Well, that concludes our formal presentation. I'll now pass it back to our moderator to begin the Q&A session.
Our first question comes from Eric Stine with Craig-Hallum. Please proceed with your question.
Hi, everyone.
Hey.
Hi, Eric.
I mean, obviously, a lot of uncertainty here heading into fiscal year 2021. Just curious, what are you hearing from school districts related to funding availability, related to release of funding, maybe purchase plans, and just what kind of confidence that it does give you, that when things hopefully return to normal in, I guess in fiscal 2022, what kind of strength that you see? I mean, is it something where you think that this industry can snap back pretty fast? Or are there factors where you think potentially it's a little more gradual than that?
It's a good question, Eric. Let me tell you my thoughts and some of it's based on experience too, in those schools that have reopened. The ones that have reopened, I'd say we are seeing volumes in the region of sort of 95% of where we've previously been, maybe 90%-95% of where we were back in 2019. That's encouraging for us. You go back to our funding mechanism, principally, property taxes. That's the principal funding mechanism for school buses. Property value's still high, property taxes are still robust. The view is that the funding certainly for traditional funding for school buses looks pretty strong. We've seen consistently over the years that when districts need to add school buses, which are all about safety of children, they'll put some bond money out there.
It'll be a unique funding mechanism for doing it, and that's been successful in the past. I think the other thing to recognize too is, try to not get political here, but we've certainly heard President-elect Biden talking about electrification of the school bus fleet. I think certainly his top of his agenda is getting kids back to school in the classroom, and I certainly think to do that effectively, you've got to have a robust school bus fleet of safe buses that can handle it. I guess what I'm telling you is based on experience of districts who've actually gone back to school, we're seeing orders.
I don't necessarily think when I think of 2022, we're going to see us bounce immediately back at 35,000, which is like the peak we've been running at for the last 30 years, and we enjoyed three or four years of that prior to the COVID pandemic. I think we'll be close to that. I don't think we'll be far off it. I think we'll be in the 33,000, 34,000 sort of range when we bounce back.
Okay. No, that's great color. Maybe just turn into this fiscal year? You mentioned that first quarter was full. In that context, should we think about typical seasonality this year, or could it potentially be a fair amount steeper? I guess in the back half of the year, COVID has a big bearing on that. Maybe just how we should think about or get our minds around first quarter?
Obviously we don't give guidance by quarter. I can tell you when I say we're full, obviously we are a little down from last year, but the decline from a year ago is a lot less than what we saw in the third quarter and then in the fourth quarter of fiscal 2020. We're much nearer just getting into double-digit decline. That's where we are as we look at the 2021 first quarter orders versus a year ago. I think that's a point we've been trying to make here is that, we talk about the rate of decline seems to be slowing down, and certainly evidence that in the first quarter. When we give you those results, you'll see that in February time.
Okay. Got it. Yeah?
This is Jeff. I think you're going to see the first half is going to continue to be impacted by COVID, and then obviously we've commented that we're optimistic on the second half, so that could play into the seasonality as we look at the full year as well.
Okay. Got it. Lastly, just on the electric bus side, I know you recently upped capacity by six times, I believe, over 1,000 units, and that's pretty significant. I know you enter with, I think, 80 coming into the year. You obviously didn't have that capacity thinking that you wouldn't need it soon. Is that a level that you think, whether it's in the next fiscal year or two, that you could be approaching on the electric bus side?
We'll be at capacity this year, but I do think you certainly look over the next couple of years, I think we'll start to see a significant increase of that capacity being used. Just to clarify too, when we talk about capacity, we talk about what we've facilitized too. We talk about our equipment, our plant, our automation. Obviously, I'm not manning to 1,000 buses today when I've got 80-unit backlog, so we'll be imprudent on that. But we've put the capability in place that when it's there, we can easily ramp up. I just look at, again, when I mentioned earlier of the new Administration, part of their campaign.
They've got to get this, by the way, through Congress and everybody's got to approve it, but he did talk about electrifying some 500,000 school buses over the next five years, which seems phenomenal. Let's be honest. You can't think about putting 500,000 new school buses on the road, but I think it's indicative of maybe the support we're going to see for school buses, so it's pretty exciting. Certainly electric buses too.
Yep. Okay, thanks everyone.
Great.
Thank you. Our next question comes from Craig Irwin with ROTH Capital Partners. Please proceed with your question.
Good evening, congratulations on tight execution this quarter.
Thanks, Craig.
choppy environment. Yeah, you guys did a great job.
Thank you.
One of the things I liked in your slides, sorry, is in the waterfall, you include a $7.9 million headwind stepping from Q4 2019 to Q4 2020. That headwind, you say, is primarily from COVID. Can you share with us what portion of that probably hit the gross margin line, given that gross margins were quite a bit lower than where things have been over the last couple of years? I know a lot of the spending for COVID does come from spacing out your employees and putting in additional hand sanitization stations and other expenses and inconveniences. Can you maybe share with us an approximation of the margin impact, either in dollars or basis points?
Yeah. Hey, Craig, this is Jeff. What I would say is of that $7.9 million headwind that we saw there in the fourth quarter, the vast majority of that certainly hit us in gross profit. That was in specific areas that do impact cost of goods sold. It's in labor, it's in overhead, and just overall manufacturing efficiencies, including loss of operating leverage from lower volume. All of those impact our cost of goods sold and subsequently slow down the gross profit. It's certainly the largest portion of it.
Great. The question I get in almost every phone call where someone mentions Blue Bird is, why are you guys not leaning in the way that so many of these SPAC IPO companies are, laying out a growth path for investment and pursuing the explosive growth that's available in EVs from diversification? You've got a proven technology out there with your school buses. You're one of the top two guys in the market. Your experience in alternative fuels is unsurpassed. I was talking to another leader in alternative fuels today, and they're growing 30%, they're going to grow 30% in 2021 plus, with potential upside to 50%. It's got to be available to you. Why not invest for that? Why not lay that out as a plan for investors? Is this a conversation at the board level? If it's not, why not?
No, it's definitely a conversation we're having at the board level, Craig. Obviously we are investing in terms of the capacity increase we've put in place and the products that We have a very robust product cycle plan too that takes from our product today to superior products for the future that I think customers are going to love and are going to value. I can't get into it today, but certainly it's something we recognize. By the way, we've seen those SPACs out there. We've seen their projected growth rates. We know the valuations. We've seen that. Certainly it's something we are talking to our board about. We're just not ready at this meeting to tell you what we're going to do or what our next steps are. I take your point, Craig. It's a good one.
We have a great platform, a great chassis. It can apply to different applications. We're talking to our board about where we take it from here.
Excellent. That is a big piece of news. We will stay tuned and look forward to future updates. Thank you.
Okay. You bet, Craig. Thanks.
There are no further questions at this time. I would like to turn the floor back over to Phil Horlock for closing comments.
Okay. Thanks, Paul. I want to thank everyone on the phone today for joining us on the call, and I really appreciate the questions there that were put to us. We do appreciate your continued interest in Blue Bird, and we look forward to updating you again on our progress next quarter. Before we sign off, though, I just want to leave you with a final message. We do believe we're well-positioned to handle this unprecedented pandemic. We've got ample liquidity, as you heard and as Jeff's talked about. We are improving our business structure. You heard about the three-pronged strategy, and we're going to do whatever it takes from a restructuring standpoint to make sure we get through this period. We are confident we'll see a rebound in the industry, and we want to be there to capitalize on it.
I also want to give special recognition to our incredible employees for their commitment and dedication to Blue Bird during this pandemic. They have been amazing when you look at our absenteeism rate and how low that is compared with traditional manufacturing industries. All credit to our team. If you have any follow-up questions, don't hesitate to call our Head of Investor Relations, Mark Benfield, who you all know well. Thanks again from all of us at Blue Bird. Have a great evening, be safe, and have a happy holiday. Thanks.
This concludes today's conference. You may disconnect your lines at this time. Thank you for your participation and have a wonderful evening.
