Thanks, Allan, and good afternoon, everyone. Fiscal 2026 represented a critical year for DocuSign as we continued our transformation, leveraging our recognized leading position amongst the world's most trusted software companies to help customers realize value from their full repository of agreements through IAM. With 1.8 million customers, representing most large enterprises, mid-market companies and over 1.5 million small businesses, we are in a unique position to provide the insights, productivity and velocity companies need to improve their performance, particularly via leveraging AI. Fiscal 2026 was both our first full year integrating IAM into our business as our primary growth driver and our first year generating over $1 billion in free cash flow. We are proud of the progress we've made over the past 3 years and aspire to even greater gains in the future. Q4 total revenue was $837 million and subscription revenue was $819 million, both up 8% year-over-year. For the full year fiscal 2026, total revenue was $3.2 billion, up 8% year-over-year and subscription revenue was also $3.2 billion, up 9% year-over-year. Revenue in Q4 and for the full year benefited from approximately 80 basis points and 20 basis points year-over-year, respectively, from foreign exchange rates. Additionally, as discussed in prior quarters, fiscal 2026 revenue also had a slight tailwind from digital add-ons that launched in late fiscal 2025. Our annual recurring revenue, or ARR, grew 8% year-over-year in fiscal 2026 to nearly $3.3 billion. This is consistent with our fiscal 2025 ARR growth rate of 8% year-over-year. ARR growth this year was driven by accelerating gross new bookings, primarily from IAM customers as well as gross retention improvements. Our ARR growth in fiscal 2025 was driven predominantly by gross retention as we made sizable gains that year. We're excited about the opportunity to accelerate our ARR growth in fiscal 2027 as we continue to become an even more valuable partner to our customers. As a reminder, and as detailed in our filings, ARR is calculated using fixed exchange rates set at the start of the fiscal year. Billings for Q4 were up 10% year-over-year and exceeded $1 billion for the first time in DocuSign's history. Approximately half of the Q4 billings outperformance relative to our guidance was driven by timing with the remainder from FX and bookings. For the full year fiscal 2026, billings were $3.4 billion, also up 10% year-over-year. Billings in Q4 and for the full year benefited by approximately 2.3% and 1.1% year-over-year, respectively, from foreign exchange rates. As a reminder, this quarter will be the last time we report on billings as a top metric as we shift to discussing ARR going forward. Please see Slide 29 in our Q4 earnings deck for a full summary of our top line metrics changes. The underlying foundation of our business remains durable and healthy. Our dollar net retention rate, or DNR, was 102% in Q4, up from 101% in the prior year showing moderate sequential improvement over the last 6 quarters. Both consumption, a measure of envelope utilization and the volume of envelope sent in Q4 continued to improve year-over-year with consumption remaining near multiyear highs across customer segments and verticals. We are seeing continued strong adoption of our IAM platform. In Q4 and after just over 18 months from launch, IAM represented over $350 million in ARR or 10.8% of total company ARR, up from 2.3% at the end of fiscal 2025. Although still early, our first IAM renewal cohorts are performing better than the company average, and we continue to see adoption rates for IAM features climb as users engage with the platform's expanding functionality. In Q4, total customers grew 9% year-over-year to over $1.8 million. We ended the quarter with 1,205 customers spending over $300,000 annually, a 7% increase year-over-year. International revenue surpassed 30% of total revenue in Q4 and grew 15% year-over-year. Our commitment to operating efficiency delivered strong profitability for the quarter and fiscal 2026. Non-GAAP gross margin for Q4 was 81.8%, down 50 basis points from the prior year due to ongoing costs associated with our cloud infrastructure migration, as discussed throughout the year. For fiscal 2026, non-GAAP gross margin was 82.0%, down 20 basis points on a year-over-year basis a better result than the anticipated full percentage point of headwind in our initial fiscal 2026 guidance as higher revenue partially offset the cloud migration impact. Non-GAAP operating income for Q4 was $247 million, up 10% year-over-year. Operating margin was 29.5%, up 70 basis points versus last year. For the full year, non-GAAP operating income was $968 million, up 9% year-over-year, with full year operating margin reaching 30% in the fiscal year for the first time in our company's history, representing a 30 basis point increase year-over-year. We ended fiscal 2026 with 7,044 employees, up modestly from 6,838 a year ago, as we continue to invest deliberately in roles focused on growing the IAM platform. While we are hiring across all of our global offices, the vast majority of our net new head count growth has come from, and we expect will continue to be in lower-cost locations. Also in fiscal 2026, we delivered our first year with over $1 billion of free cash flow, a 33% margin compared to 31% a year prior. In Q4, we generated $350 million of free cash flow, representing 25% year-over-year growth and a 42% margin. Strength in Q4 was driven primarily by improved collections efficiency as well as higher billing seasonality and the timing of billings. Our balance sheet remains strong. We ended the quarter with approximately $1.1 billion of cash, cash equivalents and investments. We have no debt on the balance sheet. In Q4, we also increased our buyback activity repurchasing $269 million in shares. This was our largest quarterly dollar buyback to date. For the full year fiscal 2026, we repurchased $869 million in stock representing 82% of our annual free cash flow. When including the additional funds used to offset taxes due on RSU vesting, this rate is slightly over 100% for the year. In Q4, we established a 10b5-1 program to repurchase shares before the open window rather than our typical buybacks that coincide with open trading windows after earnings. This mechanism extends the potential time frame for share buybacks, and we have already repurchased $158 million to date in Q1. In addition, today, we announced a $2 billion increase to our repurchase program, bringing our total remaining authorization to $2.6 billion. Our focus continues to be on improving free cash flow generation and redeploying excess capital opportunistically to shareholders. Non-GAAP diluted EPS for Q4 was $1.01, a $0.15 per share improvement from $0.86 last year. GAAP diluted EPS for Q4 was $0.44 versus $0.39 last year. For fiscal 2026, non-GAAP diluted EPS was $3.84 versus $3.55 in fiscal 2025, and GAAP diluted EPS was $1.48 versus $5.08 last year. As a reminder, GAAP earnings in fiscal 2025 were positively impacted by the tax valuation allowance released that year. In Q4 and fiscal 2026, the buyback program contributed to reducing our share count. Diluted weighted average shares outstanding for Q4 were 204.7 million, a decrease from 214.5 million last year. Basic weighted average shares outstanding for Q4 decreased by 2.8 million year-over-year to 200.5 million from 203.3 million total shares. With that, let me turn to guidance. For ARR, we anticipate accelerating growth in fiscal 2027 compared to the prior year. We expect a year-over-year growth rate range of 8.25% to 8.75% or an 8.5% year-over-year increase to $3.551 billion at the midpoint at the end of Q4 of fiscal 2027. We expect growth to be driven by gross new bookings, primarily from both new and expanding IAM customers as well as by gross retention improvements versus fiscal 2026. Related to this, we expect another year of modest improvement in DNR. We expect IAM to represent approximately 18% of our total ARR at the end of Q4 fiscal 2027, driving IAM to well over $600 million in ARR by the end of this year. This is our first year guiding to ARR and I want to provide some context on our philosophy and approach around it. Our guidance represents our current best estimates for both total ARR and IAM's trajectory based on the business data and bookings forecast available today. Therefore, we intend to only revise our ARR forecast as our underlying bookings expectations evolve for the entire year and not necessarily on a quarterly basis. As you are aware, our bookings are seasonally weighted more heavily to the second half of the year, in particular, Q4, which is typically our strongest quarter. As a result, updating our full year ARR forecast will depend on our visibility later into the year, which will take time to achieve. For total revenue in the first quarter and fiscal year 2027, we expect $822 million to $826 million in Q1 or an 8% year-over-year increase at the midpoint and $3.484 billion to $3.496 billion for fiscal 2027 or an 8% year-over-year increase at the midpoint. After adjusting for impacts from FX and the moderate tailwinds from digital add-ons in fiscal 2026, revenue growth is in line with the prior year. Beginning fiscal year 2027, we will only guide to total revenue, given that subscription revenue has now become the vast majority of our recognized revenue base, specifically 98% of our revenue in fiscal 2026. We will continue to report the breakdown between subscription and professional services and other revenue in the footnotes of our SEC filings based on materiality thresholds. For profitability, we expect non-GAAP gross margin to be between 80.8% to 81.2% for Q1 and between 81.5% and 82.0% for fiscal 2027. We expect non-GAAP operating margin to reach 29.0% to 29.5% for Q1 and 30.0% to 30.5% for fiscal 2027. Our fiscal 2027 operating margins guidance reflects a similar level of margin expansion as we saw in fiscal 2026. We expect non-GAAP fully diluted weighted average shares outstanding of 196 million to 201 million for Q1 and 190 million to 195 million for fiscal 2027, a meaningful reduction from the prior year as we expect that our buyback activity will more than offset dilution. For detailed commentary on top and bottom line factors to guidance, please see the Modeling Considerations appendix in our prepared remarks. In closing, fiscal 2026 was defined by the successful global rollout of IAM and our continued commitment to business fundamentals and improving efficiencies while redeploying excess capital to shareholders. As we look toward fiscal 2027, we remain focused on leveraging efficiency gains to drive product innovation and ultimately accelerating ARR growth delivering the long-term improvements that our customers, shareholders and employees will be proud of. That concludes our prepared remarks. With that, operator, let's open the call for questions.
