Thank you, John. Hello everyone, and thank you for joining our fourth quarter 2021 earnings conference call. When we last spoke in February, we discussed our strong Q4 results and that our 3-pillar strategy was progressing and already making the difference. Today, I'm happy to report another strong quarter with results coming in, above our expectations. Let me start by providing some color on our financial results. As expected and unlike Q1 last year, Q1 this year was impacted by COVID-19 related headwinds. Despite of these headwinds, we were very pleased with our results and execution against our 3-pillar strategic plan. Our Q1 revenue of $285 million was down slightly versus previous year, but came in above our forecasted guidance range. Importantly, our recurring revenue grew 1%, adjusted EBITDA in the quarter was $45 million up 19%, which was also above the high end of our guidance. Our Net adjusted EBITDA margin was 23%, which despite the revenue reduction was up 400 base points from last year, as we remain focused on cost management and profitability. For the full year, we're reaffirming our guidance and as previously discussed, we expect to reach the Rule of 40 this year, for the first time ever. We had some exciting new wins in the quarter, across all segments. Note, we are pleased to sign a new speed pay deal with Cascade Financial, a home loan finance company, which we will allow Cascade's customers to benefit from more ways to pay their mortgage, including via mobile wallet, using our wallet room application. We are also increasing our focus on securing with large, sophisticated and global merchants. In the quarter, we signed a new deal with Red Lobster to consolidate their payment infrastructure to one vendor, for both, their in-store and e-commerce businesses, creating a similar payment experience across all channels. We also signed a notable contract with a Middle Eastern payments facilitator, for our omni-channel commerce solution. In Europe, we signed an acquire agnostic e-commerce contract with a new UK based payment service provider. In the banking sector, we signed a new real-time contract with Stax, the largest ACH processor in France as well as an expansionary contract with Union Bank of India. Importantly, we are hearing positive feedback from our customers that we affirmed the benefits of our new fit-for-growth organizational structure, which has allowed for faster decision-making and increased responses. While we anticipate headwinds resulting from COVID related delays to continue through Q2, our strong first quarter results reaffirmed my confidence in our business. As we progress on our strategy, amid an improving economic outlook. We anticipate a strong second half performance. In addition to organic value creation, we continue to make progress on a complete strategic reveal of our business portfolio to enhance ACI's growth profile and maximize long-term value to our shareholders. With that, I will turn it over to Scott to discuss the financials. Scott?
