All right. Thank you, Emily. As Emily noted, we had another exciting and dynamic year as we continued to scale our platform, and we closed out the year on a strong note. Revenue for the quarter was $38 million, a new record for Twist, which was a sequential growth of 9% and year-on-year growth of 17%. And this brings our FY '21 revenue to $132.3 million, a 47% increase from FY '20 and slightly above the top end of our guidance of $129 million to $132 million for the year.
Orders were $45.2 million for the quarter, a sequential increase of 16% and 6% year-over-year. This takes our total orders for the year to approximately $159 million. Gross margin for the fourth quarter was 40.7%, and our total year gross margin was 39% as compared to 32% in FY '20. We shipped to approximately 2,900 customers for the year and that's up from 2,200 in FY '20.
And we ended the year with cash and short-term investments of approximately $478 million.
Health care is now our largest segment and accounts for 54% of our business with revenue of $71.2 million in FY '21 versus $40 million in FY '20. And that's a 78% growth year-on-year, reflecting growth in NGS, biopharma and growing demand for our synbio products.
Industrial chemicals revenue was $34.5 million in FY '21 versus $29.1 million in FY '20.
Even though we're operating in a pandemic where many academic labs were impacted globally, our academic revenue was $25.3 million versus $19.6 million in FY '20, reflecting our continued focus on growing the long tail.
Agricultural revenue was $1.3 million, essentially flat with FY '20.
Now I'll provide more color on orders. We ended on a very strong note with NGS orders for the fourth quarter of $21.8 million, which brings our total NGS orders for the year to approximately $76 million as compared to $53 million in fiscal '20, which is approximately 43% growth year-on-year from a high comp base we referenced earlier. This growth reinforces the robust and growing market opportunity, our expanding product portfolio, investment in our commercial organization, expanding our customer base with increased adoption and increasing NGS applications, including liquid biopsy, MRD, RNA controls and clinical applications.
During the quarter, we received orders from approximately 670 NGS customers. And the top 10 accounts placed orders of approximately $10 million as compared to approximately $7 million for the top 10 in the previous quarter, confirming we're seeing continued diversification of our customer footprint.
Our pipeline for larger opportunities continued to scale. And we're now tracking 199 accounts, and that's up from 182 we noted in our last earnings call. 88 have adopted Twist and that's an increase from 79 on our -- we noted in our last quarter.
Now turning to synbio. We saw robust growth in our synbio orders, which includes genes, DNA preps, IgG, libraries and Oligo Pools, which rose to $20.1 million in the fourth quarter, up from $15.7 million in the third quarter of FY '21, which is a sequential growth of 28% and up from $16.1 million in the last quarter of fiscal '20, with health care segment being the major driver to growth.
Now to biopharma. We continued to scale our biopharma antibody discovery business as orders rose to $11.6 million for the year, which is a growth of 123% compared to $5.2 million in fiscal '20. Orders in the fourth quarter were $3.4 million as we continued to build our pipeline of new and repeat customers. As noted earlier, we have 34 partners with 41 active programs, of which 35 are milestones and royalties. Please note, orders may not translate into revenue but do provide a trend line for each product group.
Now moving from orders to revenue. As noted earlier, revenue for the quarter was $58 million and brings our cumulative revenue for fiscal '21 to $132.3 million versus $90.1 million in fiscal '20, representing approximately 47% year-over-year growth.
NGS product revenue scaled to $21.4 million in quarter 4, a sequential growth of 14%. And it's notable that we exceeded the $20.2 million for the same quarter of FY '20, which included the $9 million we mentioned earlier. In Q4, the top 4 customers accounted for approximately 50% of our revenue. For the year, NGS revenue grew from $44 million in FY '20 to $72.7 million, which is 65% growth year-on-year.
Our synbio product revenue for the quarter was approximately $14 million, and that's down sequentially from $14.3 million in the previous quarter due to the aforementioned production issue and seasonality in Europe. Total annual synbio revenue was $53 million compared to approximately $44 million or 20% growth year-on-year. Some of the highlights include shipping to 1,900 synbio customers in FY '21, up from 1,590 in FY '20.
Our genes revenue was $39 million, and that's an increase from $35.2 million in FY '20. We also shipped a record number of genes of approximately 372,000 and that's an increase from 338,000 we shipped in FY '20.
Now to biopharma. Our revenue for the quarter was approximately $2.6 million, and full year revenue was $7 million as compared to $2.4 million in FY '20. And during the year, we serviced approximately 43 customers, demonstrating the progress we're making in expanding our platform.
I will now briefly cover our regional progress for FY '21. Our investment in building out our global commercial organization is reflected in our strong international growth. EMEA had another terrific year with FY '21 revenue of $44.1 million versus $25.8 million, and that's 71% growth year-on-year and EMEA now accounts for 33% of our worldwide business.
APAC had a great year and FY '21 revenue grew about 100% to $10.3 million from $5.1 million in FY '20.
The U.S., which includes Americas, revenue was $77.9 million for FY '21 as compared to $59.2 million for FY '20.
Now moving down the P&L. Our gross margin for the quarter was approximately $15.5 million or 40.7% of revenue, up from 40% in the prior quarter. Total year margin was approximately $51.7 million or 39% of revenues, up from 32% in FY '20.
Now to operating expenses. Our quarter 4 operating expenses, which includes R&D and SG&A, was $57.7 million. R&D for the quarter was $19.4 million, which brings our total investments in R&D to $69.1 million for FY '21 and that's up from $43 million in FY '20. The major contributors to our investments in R&D were compensation due to higher head count and external services, primarily associated with our investment in DNA storage and also increased investment in biopharma.
Our SG&A in quarter 4 was $38.2 million, which brings our SG&A for the year to $135.9 million as compared to $103.3 million in FY '20. The increases are primarily higher compensation as we continued to build out of commercial organization, increased stock-based compensation, higher fees associated with the audit and investments in addressing our material weaknesses and increased lease expenses as we expanded our footprint in San Francisco and the Factory of the Future in the Portland area.
Our net loss before tax was $41 million for quarter 4. And our total loss for the year was $152 million, which includes stock-based compensation of $37 million and depreciation and amortization of $10 million. CapEx for the year was $27 million, including $13 million for Wilsonville, mostly for equipment deposits and facility improvements.
Given the supply -- global supply chain challenges, we have strategically increased our inventory to $32 million compared to $12 million at the end of fiscal 2020.
We ended the year with cash and short-term investments of approximately $478 million.
Now here are some updates on our FY '22 guidance. As we noted, we saw strong bookings in quarter 4 and are optimistic on our opportunities, and at the same time, there remains uncertainty associated with the pandemic. For FY '22, our revenue guidance is in the range of $173 million to $181 million. And including the expected completion of the Abveris acquisition in quarter 1 fiscal '22, our revenue guidance increases to $183 million to $193 million.
Synbio revenue is estimated to be in the range of $67 million to $70 million as compared to approximately $53 million in fiscal '21. Our NGS guidance is estimated to be in the range of $94 million to $96 million as compared to approximately $73 million in fiscal '21. Biopharma revenue, including our anticipated Abveris acquisition, is estimated to be approximately $22 million to $27 million as compared to approximately $7 million for fiscal '21.
For the first quarter, we're projecting revenue in the range of $37 million to $39 million, which we believe is prudent guidance reflecting the upcoming holiday shutdowns in Europe, COVID pressures and the impact of the production issue we discussed earlier on the call.
Our fiscal '22 gross margin projection range is 35% to 37%, and, which reflects the costs associated with our Wilsonville wrap-up. Excluding these costs, gross margin will be 42% to 44%.
Operating expenses, which includes R&D and SG&A, are expected to be approximately $315 million for fiscal '22 as compared to $205 million in fiscal '21, reflecting increased investments in biopharma, approximately $40 million; data storage, $20 million; our commercial organization, $20 million; and Portland OpEx start-up costs of $10 million plus there's higher stock-based comp and higher depreciation.
Our R&D expenses for the year are projected to be approximately $130 million, up from $69 million, primarily due to investments in data storage and biopharma.
Our net loss guidance for the year is expected to be approximately $250 million. Stock-based comp is projected to be approximately $47 million. And depreciation is expected to be $13 million.
Our CapEx for FY '22 is projected to be $80 million to $90 million with approximately $75 million investment in Wilsonville.
In summary, we'd like to thank all the Twisters for delivering another terrific quarter with record growth. We had another exceptional year continuing to execute on our strategy, enjoying broad demand from our customer base and we're significantly stepping up our investment as we continue to tap into new revenue streams.
And with that, I'll now turn the call back to Emily.
