Elizabeth Rafael
Interim Chief Financial Officer at Autodesk
Thanks, Andrew. Q3 was another strong quarter. We generated broad-based underlying growth across products and regions. In addition, we saw revenue increases from the new transaction model and M&A, which were offset by the absence of enterprise business agreement true-ups from Q3 last year and FX. Our Make products continue to enhance growth driven by our ongoing strength in construction and Fusion. Overall, macroeconomic, policy, and geopolitical challenges, and the underlying momentum of the business, were consistent with the last few quarters with continued strong renewal rates and headwinds to our new business growth.
Total revenue grew 11%, and 12% in constant currency. By product in constant currency: AutoCAD and AutoCAD LT revenue grew 8%; AEC revenue, which was most impacted by the absence of true-up revenues, grew 12%; manufacturing revenue grew 16%, and still comfortably in double digits excluding up-front revenue; and M&E revenue grew 15%, boosted by the PIX acquisition and associated integration adjustments.
By region in constant currency: revenue grew 11% in the Americas, which was most impacted by the absence of true-up revenues, 13% in EMEA, and 14% in APAC. The mechanical contribution from the new transaction model to revenue was $17 million in the third quarter and $25 million on a year-to-date basis. Direct revenue increased 23% and represented 42% of total revenue, up four percentage points from last year, benefiting from strong growth in both EBAs and the Autodesk Store, and also the natural tailwind to revenue from the new transaction model.
Net revenue retention rate remained within the 100% to 110% range at constant exchange rates. Billings increased 28% in the quarter, reflecting a tailwind from the prior year's shift to annual billings for most multi-year contracts, early renewals, and the natural tailwind from the transition to the new transaction model. Similar to last quarter, and as expected, co-terming negatively impacted billings ahead of the launch of the new transaction model in Western Europe. The natural contribution from the new transaction model to billings was $72 million in the third quarter and $108 million on a year-to-date basis.
Total deferred revenue decreased 9% to $3.7 billion and was again impacted by the transition from up-front to annual billings for multi-year contracts. Total RPO of $6.1 billion and current RPO of $4.0 billion grew 17% and 14%, respectively, which reflect a tailwind from early renewals and the new transaction model, and a headwind from the declining contribution of billed and unbilled deferred revenue from large multi-year and EBA cohorts ahead of renewal in fiscal '26. Excluding these, current RPO growth was broadly consistent with Q2. We do expect the new transaction model and the larger FY '26 renewal cohorts to have a greater impact on both RPO and current RPO growth in Q4 of fiscal '25.
Turning to margins, GAAP and non-GAAP gross margins were broadly level. With Autodesk University shifting back to Q3 this year from Q4 last year, GAAP and non-GAAP operating margins decreased by 2 percentage points and 3 percentage points, respectively. The timing effect from AU obviously washes out over the full year.
At current course and speed, the ratio of stock-based compensation as a percentage of revenue peaked in fiscal '24, will fall by more than a percentage point in fiscal '25, and will be below 10% over time. Free cash flow for the quarter was $199 million. This benefited from some channel partners in Western Europe booking business earlier in the quarter ahead of the transition to the new transaction model really to de-risk month one after the transition. This accelerated free cash flow to the third quarter which was partially offset by the expected negative impact of co-terming in Western Europe.
Turning now to capital allocation, we continue to actively manage capital within our framework and deploy it with discipline and focus through the economic cycle to drive long-term shareholder value. As expected, the pace of buybacks picked up in the third quarter. We purchased approximately 1.2 million shares for $319 million, at an average price of approximately $269 per share.
We will continue to deploy capital to offset and buy forward dilution as our free cash flow grows from the fiscal '24 trough. This practice has reduced our share count by about 5 million shares over the last three years with an average percentage reduction of about 70 basis points per year. We increased the amount authorized under our share repurchase program by $5 billion, for a total of approximately $9 billion. This extends our flexibility over the medium term with the precise trajectory remaining dependent on our debt repayment schedule, as well as the ebb and flow of M&A.
Now, let me finish with guidance. As we said in February, the pace of the roll out of the new transaction model will create noise in billings and the P&L, so we think free cash flow is the best measure of our performance. Taking out that noise, the underlying momentum in the business remains consistent with the expectations embedded in our guidance range for the full year with continued strong renewal rates and headwinds to new business growth. Our sustained momentum in the third quarter, and smooth launch of the new transaction model in Western Europe, reduce the likelihood of our more cautious forecast scenarios. Given that, we're raising the mid-points of our billings, revenue, margins, earnings per share, and free cash flow guidance ranges.
So, let me give you a little bit more detail. The underlying momentum of billings is in line with our expectations. Compared to our modeling at the start of the year, the launch of the new transaction model in Western Europe in Q3 and early renewals have been a tailwind to billings. Whereas more co-terming, more business done under the old buy/sell model before the launch of the new transaction model, and in recent weeks, FX movements, have been headwinds to billings. We now estimate that the new transaction model will provide between a 5 percentage point and 5.5 percentage point tailwind to billings growth in fiscal '25. We've raised the mid-point of our fiscal '25 billings guidance by $10 million to a range of $5.90 billion to $5.98 billion.
The underlying momentum of revenue is also in line with our expectations. We estimate the new transaction model will provide around a 1 percentage point to 1.5 percentage point tailwind to revenue growth in fiscal '25. Up-front revenue contributed 2 percentage points to revenue growth in Q4 of fiscal '24 and therefore this is a headwind in Q4 of fiscal '25. While not large enough to call out at the start of the year, it was already factored into our Q4 and our full-year modeling. We've raised the mid-point of our fiscal '25 revenue guidance range by $18 million to a range of $6.12 billion to $6.13 billion.
We're increasing our GAAP and non-GAAP margin guidance mid-point by 25 basis points by raising the bottom end of both ranges by 50 basis points. The GAAP margin guidance range is now 21.5% to 22%. The non-GAAP margin guidance range is now 35.5% to 36%, which includes a 1 percentage point to 1.5 percentage points underlying margin improvement broadly offset by the margin headwinds from the new transaction model and related incremental investment in people, processes, and automation.
The underlying momentum of free cash flow is also in line with our expectations. The headwind to billings from co-terming and FX rates, that I mentioned earlier, is being offset by early renewals, faster collections and improved underlying margins. We've raised the mid-point of our fiscal '25 free cash flow guidance by $10 million and tightened the range to $1.47 billion to $1.5 billion. We expect strong free cash flow growth in fiscal '26, because of the return of our largest multi-year renewal cohort, the natural mechanical stacking of multi-year contracts billed annually, and a larger EBA cohort. With our current trajectory, we still estimate free cash flow in fiscal '26 to be around $2.05 billion at the mid-point.
The slide deck on our website has more details on modeling assumptions for Q3 and for the full fiscal year '25. While this may be my last earnings call for Autodesk, I will stick around for a bit to ensure a smooth transition for Janesh. Thank you, Andrew, and everyone at Autodesk, for your support while I was here, and to the many investors and analysts with whom I've had lively discussions over the last few quarters.
While the transition to annual billings for multi-year contracts and the deployment of the new transaction model has created noise in billings and the P&L, they do provide a natural near-term tailwind to revenue and free cash flow growth. Combined with a resilient business model, sustained competitive momentum, Autodesk has enviable sources of visibility and certainty in a very uncertain world. For all these reasons, I step down from my role as interim CFO with tremendous optimism for the future.
Andrew, back to you.
