Thanks, Mark, and good morning and good afternoon to everyone. Overall, as Mark mentioned, this quarter's financial performance aligned with our expectations we communicated in late February. Looking at the first quarter results in more detail, starting with the top line, total net revenue of $266 million declined 6% versus the year-ago quarter, driven by the expected competitive pressure in Suboxone film and our decision to discontinue PERSERIS last July. By geography, total US net revenue in the first quarter declined by 8%, versus the year-ago quarter driven by these same dynamics. Rest of world was up 3% on a reported and 1% on a constant currency basis. The rest of the world Q1 of last year was negatively impacted by shipment timing, as we had mentioned last year. Overall, SUBLOCADE's performance in Q1 was in line with our expectations. Total SUBLOCADE net revenue declined 2% in the first quarter, versus the same year-ago quarter. We continue to see good growth from SUBLOCADE outside the US net revenue up 8% to $13 million. SUBLOCADE's US performance reflected solid dispense volume growth in the OHS channel, that was partially offset by near-term funding challenges among certain justice system accounts that resulted in significantly lower dispense volume from this channel. Lower pricing from higher rebating activity and unfavorable channel mix resulted in modestly lower net revenue year over year. On a sequential basis, SUBLOCADE's US net revenue declined 9%, reflecting a 6% decline in dispense volume, coupled with destocking in the quarter. This performance coupled with our updated cohort and new patient share data reinforced the midpoint of our full-year guidance for SUBLOCADE net revenue of $725 million to $755 million, which we are confirming today. Opti net revenue was immaterial in the first quarter, as we continue to roll out trialing programs and work to ensure the medicine is included in standing orders across all states. We continue to expect full-year net revenue of $10 million to $15 million including an $8 million product order from BARDA. Turning to Suboxone Film in the US. The average share of approximately 15% in the first quarter was in line with our planning expectations and down approximately three percentage points versus the same year-ago quarter. The current quarter did benefit from a prior quarter trade spend release in the mid-single-digit millions. As we mentioned in February in our 2025 guidance discussion, the generic film price eroded at the end of full year 2024 and we took the appropriate actions to maintain formulary access in Q1. Our full-year 2025 guidance still assumes further price erosion throughout the year. As a reminder, we do not promote Suboxone film in the US. Moving down to P&L. Our first quarter gross margin of 83% was down versus the prior year quarter. Q1 2024 included the benefit of saleable process validation batches of SUBLOCADE, from our expanded production capacity by our contract manufacturer. I do want to briefly discuss a topic on most investors' minds these days. Tariffs. We are closely monitoring the evolving landscape mindful that these things change daily. As the landscape currently stands, and based upon the geographical makeup, of our primarily US cost of goods sold, and manufacturing activities, we believe the potential tariff impacts are manageable, and within our non-GAAP gross margin guidance range of a low to mid 80% for the full year. Moving on to operating expenses. Non-GAAP adjusted SG&A expenses were $130 million in the quarter, down 8% versus Q1 of last year. The decrease primarily reflects our streamlining actions, the discontinuation of PERSERIS, and an accrual release in the low to mid-single digits related to the mandated IRS Pharma branded fee, which still may have to be adjusted later in the year upon final invoice. R&D expenses were $22 million, a decrease of 19% versus Q1 of last year. This decrease reflects the reprioritization of pipeline activities solely to our Phase two OUD assets and the previously mentioned cost savings. Our first quarter non-GAAP adjusted operating income of $59 million was down 10% from Q1 of last year, due primarily to the Suboxone film and PERSERIS net revenue dynamics, partially offset by the streamlining activities on our cost basis. Non-GAAP adjusted net income of $51 million decreased 11% versus Q1 of last year reflecting the dynamics I just highlighted in addition to an increase in net finance expenses. Our effective tax rate for Q1 was 19%, primarily benefiting from certain UK deductions. For the full year, we are still expecting an effective tax rate of 22% to 25%. Lastly, on our P&L, our non-GAAP adjusted earnings per share decreased 2% to $0.41 reflecting a lower non-GAAP adjusted net income partially offset by an approximate 9% lower diluted share count. Quickly touching on the balance sheet. Our capital position, we ended the first quarter with gross cash and investments of $400 million higher than expected due to a decrease in net working capital from delayed Medicaid billing of approximately $100 million in the quarter. Material cash outflows during Q1 included scheduled annual settlement payments, of $65 million to the DOJ RB, and Humana and same team. Looking ahead, we expect to maintain good financial flexibility and to continue our disciplined capital allocation strategy. In the near term, as we discussed in February, this remains focused on reinvesting to fuel our base business towards our net revenue goals meeting our stakeholder obligations. Moving to slide eight. At this point in the year and with the visibility we have in trends for the balance of the year, remain confident we are on track to deliver financial results we articulated in February. Before concluding, we now expect to file our 10-Q early next week, which will contain relevant litigation developments. I'll simply note at this time that earlier this week, the court granted our motion to dismiss the US shareholder claims against us. Although the court granted the plaintiffs thirty days to amend their complaint. Also, we continue to make progress towards a definitive opioid MDL settlement consistent with our existing accrual. Beyond that, there are no other major litigation updates worth noting. I will now turn the call back over to Mark.
