Thank you, John, and thank you, everyone, for joining us today. Let's turn to Slide 5. As I walk through the details on the fourth quarter, I will underscore the important dynamics that impact 2023 guidance. Some of these dynamics started taking shape in the fourth quarter of 2022 and further solidified in the first quarter of 2023. We previewed some of these themes on the third quarter earnings call in the context of our preliminary 2023 revenue outlook, namely 6 of the largest programs across the portfolio which combined generated nearly $115 million of revenue in 2022 will face significant revenue headwinds in 2023. Now let's get into the details, starting with revenues. Fourth quarter revenues declined 26% to $47.3 million. Revenues for our security solutions business declined 11% to $30.3 million, primarily due to the final ramp down of the U.S. census program in the fourth quarter of 2021 and a more than 50% reduction in revenues on the second largest program in security solutions due to a lower volume of customer activity on that program partially offset by higher revenues and information assurance. The 50% reduction in revenues on the second largest program in security solutions reflects the ebbs and flows of customer mission requirements on that program and will persist into 2023 on an annualized basis, creating a large year-over-year headwind. In addition, the largest program in security solutions has descoped by approximately 80% since the end of the year, and the third largest program in security solutions has terminated entirely. Neither of these two programs had an adverse revenue impact on the fourth quarter, but will create significant revenue headwinds in 2023. In total, the three largest programs in security solutions generated approximately $70 million in revenues in each of 2021 and 2022, and each of them will experience revenue declines of approximately 50% to 100% in 2023. On the third quarter earnings call, we described these programs as large programs that will potentially slow down and/or turn off sometime around the end of 2022 or the first quarter of 2023. Turning to secure networks. Fourth quarter revenues declined 43% to $17.1 million. The decline was driven by 3 of the largest programs in secure networks, all of which are winding down and coming to successful completion. Combined, these 3 programs generated $69 million in revenue in 2021 and $44 million in 2022. We expect these 3 programs to generate single-digit revenues in 2023. We started highlighting the wind down of these large programs on our fourth quarter earnings call a year ago and they are ramping up as expected. Now let's discuss profitability. Fourth quarter gross profit declined 24% to $18.3 million due to the decline in revenue partially offset by higher gross margin. Fourth quarter gross margin increased 95 basis points to 38.6%. Gross margin expanded primarily due to a more favorable revenue mix between security solutions and secure networks. Security solutions revenues comprised 53% and of total company revenues in 2021 and 64% in 2022. Security solutions gross margin contracted approximately 650 basis points due to the previously mentioned 50% revenue decline in a large high-margin program. Secure networks gross margin expanded approximately 250 basis points due to the previously mentioned revenue decline in large lower-margin programs. We delivered $5.4 million of adjusted EBITDA and an 11.4% adjusted EBITDA margin. Adjusted EBITDA excludes the impact of a $2.8 million restructuring charge resulting from severance and other related benefit costs associated with a reduction in force. In anticipation of lower revenues in 2023, we reduced our employee base by approximately 20% and through a series of actions starting in the fourth quarter, including a reduction in force and managed attrition. Personnel counts is lower company-wide including direct staff and indirect staff across all departments as well as among all levels of seniority, including a smaller executive team. We continue to review our cost base and investments and may take additional actions that could result in various forms of restructuring charges as the year progresses. Now let's turn to free cash flow and liquidity. Free cash flow for the full year increased from a $5.9 million net outflow in 2021 to an $11.2 million net inflow during 2022 and due to strong collections driving lower receivables. We deployed the entirety of our free cash flow to repurchase 1.6 million shares during the year. We ended 2022 with over $119 million of cash on our balance sheet. During the fourth quarter, we also closed on a $30 million senior secured revolving credit facility with an additional $30 million expansion feature. The credit facility remains undrawn, and we currently have no debt. Our balance sheet is well positioned to support the company through a wide range of operating conditions. Let's turn to Slide 6 to discuss the revenue bridge from 2022 actual results to our 2023 guidance and the evolution of our outlook since we first provided a preliminary view on our last earnings call 4 months ago. The revenue bridge is primarily comprised of 5 components, including large programs that are coming to successful completion, lower revenues on existing programs and the program loss, partially offset by new programs under contract and potential new business wins. Let's take each in turn, starting with the successful completion of large programs. We expect approximately a $45 million headwind, primarily from the 3 large programs and secure networks that are coming to successful completion. This assumption has not changed since our third quarter earnings call. Turning to lower revenues on existing programs. We expect approximately a $45 million headwind on 2 of the largest programs in security solutions and 1 of the largest programs in secure networks. This assumption is also unchanged since our third quarter earnings call. Turning to program losses. We expect a $10 million revenue headwind from a single program in security solutions that terminated at the end of the year. This assumption is consistent with our preliminary outlook. Next, we expect approximately a $13 million tailwind on new programs that are starting in 2023. This assumption is $10 million lower than previously expected, primarily due to TSA PreCheck. The soft launch of our TSA PreCheck program is well underway but our nationwide launch has not yet begun. So we have adjusted our revenue assumptions accordingly. Lastly, we're assuming a very modest $2 million tailwind from new business wins. We're only including in our guidance, new programs that we have already won have signed contracts in place and are executing. Our preliminary revenue outlook in November reflected our broader portfolio of pipeline opportunities. But for purposes of setting guidance, we're assuming new business wins in 2023 will primarily occur late in the year with revenue recognition beginning in 2024. There is potential upside to this assumption, but we feel this is an appropriate assumption to start the year. We can pull additional new business wins into our guidance from our funnel of pipeline opportunities as they occur. Let's turn to Slide 7 for the overall guidance picture. For 2023, we forecast sales in the range of $115 million to $140 million and an adjusted EBITDA loss of $17 million to $27 million. We forecast security solutions revenue to decline low 30% to high 40% due to the previously mentioned headwinds on the segment's three largest programs partially offset by the initial ramp of TSA PreCheck. We forecast secured networks revenue to decline low to high 40% primarily due to the previously mentioned wind down of large programs as expected. Gross margins are likely to be lower as a result of revenue pressure on higher-margin programs partially offset by slightly better mix of revenues between security solutions and secure networks at the top end of the guidance range. Turning to expenses. Share-based compensation is expected to be lower by approximately $25 million to $30 million, primarily as a result of the final vesting and amortization of substantially all IPO-related grants through the end of 2022. Cash below-the-line expenses, excluding stock-based compensation, restructuring costs and D&A are forecasted to be approximately $4.5 million lower primarily due to $6.5 million of lower labor costs, partially offset by $2 million of higher miscellaneous other costs. This excludes any impact from potential future restructuring costs associated with the ongoing review of our spending and investments as well as our management reserves. For the purposes of setting guidance, we've included an unallocated management reserve in our below-the-line expenses in the event we have opportunities to make further investments in support of the growth initiatives that John will discuss next. The management reserve ranges from $2 million at the low end of guidance to $7 million at the high end of guidance. Including the management reserve, cash below the line expenses range from $2.5 million lower to $2.5 million higher year-over-year. Layering in the impact of depreciation and amortization, net of capitalization of R&D, would add another $1 million to below-the-line expenses. Potential upside opportunities to our overall guidance includes new business wins that could occur earlier than expected and contribute to 2023 revenue. Potential additional cost actions over the course of the year and non-utilization of the previously mentioned management reserve. Let's turn to Slide 8 to discuss our guidance for the first quarter. For the first quarter, we forecast sales in a range of $30 million to $33 million and an adjusted EBITDA loss of $4.5 million to $6.5 million. We forecast security solutions revenues to decline mid-20% to mid-30% and secured networks revenues to decline mid-40% to high 40% and both due to the same large program dynamics described for the full year. Gross margin is expected to contract by approximately 300 basis points to 400 basis points, primarily due to revenue pressure on high-margin programs partially offset by a more favorable revenue mix between security solutions and secure networks. Cash below the line expenses, excluding stock-based compensation, restructuring costs and D&A are forecasted to be approximately $1 million to $2 million lower primarily due to lower labor costs. Layering in the impact of depreciation and amortization net of capitalization of R&D would deduct approximately $1 million from the cash numbers due to capitalization of R&D being higher than depreciation and amortization. With that, I'll pass it back to John, who will discuss 2023 business development priorities and wrap up the presentation. John?
