Thank you, Aaron. I'll cover the key financial highlights and our outlook. You can find the complete set of financial tables in our news release on our investor relations website. We are pleased to end the year with strong financial results. For the full year, we outperformed our guidance for both revenue and adjusted EBITDA margin. Revenue of $787 million increased 8% year over year, including a negative impact from FX of two percentage points. Within that, Udemy Business revenue increased 18% for the year, while consumer revenue was down 5%, including a negative impact from FX of two percentage points in both segments' growth rate. On the bottom line, we delivered $43 million in adjusted EBITDA or a 5% margin. What's particularly exciting is how far we've come in just two years, having delivered an adjusted EBITDA loss of nearly $50 million in 2022. A testament to the disciplined execution of our strategy and the resilience of our business model even amid a dynamic macroeconomic environment. That said, 2025 will be a transition year for us, as we execute on our strategic priorities Greg laid out, so we remain measured in our outlook. I'll get to that in a moment. Now I'll review the highlights. Fourth quarter revenue increased 5% year over year to nearly $200 million. With more than 60% of our total revenue coming from outside of the US, we had a negative impact from FX to our year-over-year growth rate of two percentage points. We ended the year with Udemy Business annual recurring revenue or ARR of $517 million, up 11% from a year ago, while ARR from large enterprises was up 12%. Udemy Business revenue for the quarter was $130 million, an increase of 13% year over year, including a two percentage point headwind from changes in FX rates. For Q4, we added approximately 250 new Udemy Business customers, increasing our global customer base by 9% year over year to more than 17,000. Within that total, more than 5,600 are large enterprises, an 11% increase year over year. We were also encouraged that we only experienced a single point decline for both total and large enterprise net dollar retention rate this quarter. Our consolidated NDRR at quarter end was 98%, while the rate was 103% for large customers. The rate of decline has slowed compared to prior periods, signaling that our retention dynamics are stabilizing. This is important as it reflects the strength of our customer relationships and the effectiveness of our effort to drive deeper engagement even in a budget-constrained environment. Gross margin for our Udemy Business segment came in at 75% for the fourth quarter, up 600 basis points from the prior year, primarily due to the instructor revenue share change that went into effect on January 1, 2024. We lowered the instructor take rate again on January 1 to 17.5%, which we expect will contribute another 200 basis points of gross margin expansion for the full year. As a reminder, the take rate will move down to 15% next year, which will provide an additional tailwind to our margins in 2026. Turning to the consumer segment, as expected, fourth quarter consumer revenue of $70 million was down 7% on a year-over-year basis, including a negative two percentage point impact from FX. The year-over-year decline was primarily driven by lower individual course purchases and was somewhat offset by growth from our personal plan subscriptions. Despite revenue headwinds, Udemy's marketplace remains vibrant, instructors added well over 5,000 courses each month during the fourth quarter. As we move down the P&L, note that all financial metrics are non-GAAP unless stated otherwise. Q4 total company gross margin was 64%, a 500 basis point improvement from Q4 of 2023. The improvement was driven by the instructor revenue share change as well as a continued revenue mix shift to Udemy Business, which accounted for approximately 65% of total revenue in the quarter, an increase of 400 basis points year over year. Total operating expense was $150 million or 58% of revenue, 200 basis points lower than Q4 of last year, primarily driven by our cost savings initiatives. On the bottom line, we delivered net income of approximately $60 million or 8% of revenue. Adjusted EBITDA was approximately $90 million or 10% of revenue, representing a nearly 800 basis point expansion year over year. The better-than-expected adjusted EBITDA result was driven by our revenue outperformance, ongoing focus on operational efficiencies, and cost savings initiatives. We recognized $5 million in non-recurring restructuring charges in the quarter. Which brings us to our key cash flow and balance sheet items. We ended 2024 with $356 million of cash, cash equivalents, restricted cash, and marketable securities, while free cash flow for the year was a positive $38 million. We also used $150 million in cash to buy back 60 million shares through a repurchase program during the year. In line with our strategic priority to drive operational efficiencies, we are committed to disciplined expense management. Over the past few months, we have taken deliberate steps to ensure that our business model is resilient and consistently generates cash flow. By focusing on initiatives that deliver high returns and support scalable revenue, Udemy is well-positioned to generate cash flow even in periods of macroeconomic uncertainty. Our efforts have allowed us to deliver meaningful margin expansion while also converting a greater percentage of revenue to cash flow. With more than 65% of our revenue and growing now coming from subscription-based offerings, including Udemy Business and personal plan subscriptions, we have a high degree of revenue visibility and predictability. Looking ahead, we remain disciplined in how we deploy capital. Our priorities remain, first, reinvest in the business to fuel sustainable growth, second, explore opportunistic M&A that aligns with our strategic objectives, and third, return excess cash to shareholders when appropriate. Now to turn to our guidance and introduce our outlook for 2025. We are cautiously optimistic about the year ahead and our ability to remain agile navigating evolving market conditions. As you can see from our strategic priorities, our focus is on building our foundation to drive long-term sustainable profitable growth while managing costs prudently, accelerating innovation, and delivering value for our stakeholders. For full-year 2025 revenue, we expect to be in the range of $787 to $803 million, representing flat to up 2% year-over-year growth, including a two percentage point headwind from FX assuming exchange rates remain constant. For modeling purposes, the midpoint of the guidance implies Udemy Business revenue increases approximately 5% year over year, including approximately one point of headwind from FX. As we noted on our Q3 call, 2025 Udemy Business revenue growth is expected to be impacted by the $20 million reduction in SMB sales capacity. We continue to expect revenue from large enterprises to grow faster than that from SMBs. For consumer, the midpoint of guidance implies revenue for the year to be down approximately 6% year over year, including a negative three percentage point impact from FX. As you heard from Greg and Aaron, revitalizing the marketplace and returning to segment growth is a priority for us. On the bottom line, we expect to deliver full-year adjusted EBITDA of $75 million to $85 million or approximately 10% of revenue at the midpoint. We are raising our expectations for full-year adjusted EBITDA by approximately $10 million, giving greater visibility into 2025. With respect to the first quarter, we expect revenue to be between $195 million and $199 million, representing roughly flat growth year over year at the midpoint. Assuming exchange rates remain constant, FX is expected to negatively impact Q1 revenue growth by two percentage points. For modeling purposes, the midpoint of the guidance implies Udemy Business revenue increases approximately 7% year over year, including a negative one percentage point impact from FX, while consumer revenue would be down 10% year over year, including a three percentage point negative impact from FX. On the bottom line, we expect to deliver adjusted EBITDA of $17 million to $19 million or approximately 9% of revenue. As a reminder, Q1 includes some redundant OpEx expenses tied to our $50 million cost savings initiatives. Looking ahead, while 2025 is a transition year, we expect the work we have completed to restructure the organization sets us up to improve our growth in 2026 and beyond. Given the efficiency actions, we have increased confidence in delivering our target of $130 million to $150 million in adjusted EBITDA in 2026 and continue expanding towards our target of 20% adjusted EBITDA margin in 2027. In closing, as we navigate an environment where change is accelerating at an unprecedented pace, creating a greater need for workforce upskilling and a significant opportunity for Udemy, we remain committed to a balanced approach between growth and profitability. By doubling down on our scalable marketplace model and accelerating product innovation, we are well-positioned to take advantage of the massive opportunity ahead. We look forward to keeping you updated on our progress. So with that, we'll open the call for your questions. Moderator?
