Thank you, Vibhuti. Good afternoon, everyone. Now I would like to review the results of the fourth quarter of fiscal year 2025. Net revenue for the quarter was $290.5 million, which is at the high end of our guidance range of $278 million to $290 million. Revenue was up 2% sequentially and on a year-over-year basis, was up 15.3%. Operating margin for the fourth fiscal quarter was 14.4% at the high end of our guidance range of 12.5% to 14.5%. Operating margin decreased 230 basis points from the prior quarter and on a year-over-year basis was up 350 basis points. EPS at $0.13 was also at the high end of our guidance range of $0.10 to $0.13 and was down $0.02 sequentially. On a year-over-year basis, EPS was up $0.05. Moving on to our Q4 results by business segment. Given Viavi's revenue growth and recent acquisition, the service enablement revenue as a percent of total revenue is lower and led us to combined network enablement, NE and service enablement, SE into one reportable segment, Network and Service Enablement or NSE. The ongoing reportable two segments would be NSE and OSP. NSE revenue for the fourth fiscal quarter came in at $209.1 million which is above the midpoint of our guidance range of $203 million to $213 million. On a year-over-year basis, NSE revenue was up 14.8% as a result of strong demand for fiber lab and production products, mainly driven from the data center ecosystem as well as growth in aerospace and defense products, including the acquisition of Inertial Labs. NSE gross margin for the quarter was 62.2%, which is 10 basis points higher on a year-over-year basis. NSE's operating margin for the quarter was 4.7%, an increase of 290 basis points on a year-over-year basis. NSE operating margin was slightly lower than the midpoint of our guidance range of 4% to 6%, mainly as a result of fiscal year-end employee variable costs as well as higher R&D expenses. OSP revenue for the fourth fiscal quarter came in at $81.4 million, which is above the high end of our guidance range of $75 million to $77 million, and was up 16.6% on a year-over-year basis. The increase in revenue for the quarter was primarily a result of strength in anticounterfeiting and other products. OSP gross margin was 54.7%, up 170 basis points from the same period last year and was primarily driven by higher volume and favorable product mix. OSP margin was 39.4%, which is above our guidance range of 36% to 38% and is an increase of 460 basis points on a year-over-year basis as a result of a higher fall through. Moving on to the full year results of fiscal year 2025. For the full fiscal year, revenue was $1.84 billion, which is up 8.4% on a year- over-year basis. The revenue growth was mainly driven by strong demand for lab and production and field products, primarily from the data center's ecosystem. This was partially offset by a decline in spend for wireless and cable products by NEMs and service providers. We also saw growth in our aerospace and defense products, including the acquisition of Inertial Labs. For OSP, we saw growth in our anticounterfeiting and other products as the industry's inventory levels normalized. Operating margin for the full year was 14.2%, up 270 basis points from fiscal year 2024 and was driven by higher revenue and favorable product mix, resulting in a higher fall-through. Full year EPS was $0.47, up $0.14 from the prior year. Moving on to the balance sheet and cash flow. Total cash and short-term investments at the end of Q4 were $429 million compared to $40.2 million in the third quarter of fiscal 2025. Cash flow from operating activities for the quarter was $23.8 million versus $26.2 million in the same period last year. During the quarter, we did not purchase any shares of our stock. For the full year, we purchased 2 million shares for about $16.4 million. We have almost $200 million remaining under our current authorized share repurchase program. In fiscal year 2025, we prioritized our capital allocation towards M&A with the acquisition of Inertial Labs and the pending acquisition of Spirent's high- speed Ethernet, network security and channel emulation business lines. The fully diluted share count for the quarter was 227 million shares, up from 224.2 million shares in the prior year and versus 227.4 million shares in our guidance for the fourth fiscal quarter. CapEx for the quarter was $5.5 million versus $3.8 million in the same period last year. CapEx for the full fiscal year was $27.8 million, versus $19.5 million in the prior year. Moving on to our first quarter guidance. Historically, Q1 is a softer quarter relative to Q4. However, we expect the first fiscal quarter revenue to be slightly up sequentially. For NSE, we expect first fiscal quarter revenue to be slightly up relative to the prior quarter, which reflects a seasonally strong quarter, driven mainly by data center ecosystem as well as aerospace and defense and offset by continued weakness in wireless. For OSP, we also expect quarter-over-quarter revenue to be slightly higher, driven by seasonally stronger 3D sensing products. For the first fiscal quarter of 2026, we expect revenue in the range of $290 million and $298 million. Operating margin is expected to be 15%, plus or minus 40 basis points and EPS to be between $0.13 and $0.14. We expect NSE revenue to be approximately $211 million, plus or minus $3 million with an operating margin of 5.8%, plus or minus 40 basis points. OSP revenue is expected to be approximately $83 million, plus or minus $1 million, with an operating margin of 38.3%, plus or minus 20 basis points. Our tax expenses for the first quarter are expected to be around $8.5 million, plus or minus $500,000 as a result of jurisdictional mix. We expect other income and expenses to reflect a net expense of approximately $5 million, and the share count is expected to be around 228.6 million shares. Our guidance does not include financial performance from our announced acquisition of certain Spirent's business lines, and we currently estimate the transaction to close by the end of September. During the fourth quarter, we successfully priced and allocated a $600 million Term Loan B, which will be used to fund the transaction at close as well as general corporate purposes. The Term Loan B will close concurrently with the transaction. Over the long term, we target a 4x gross leverage and below 3x net leverage. With that, I will turn the call over to Oleg. Oleg?
