More than 80% of our revenue in fiscal year 2022 came from recurring sources and sections of -- and add sections of our P&L continue to outgrow all others. We look for acquisition targets that have untapped recurring revenue sources and we continue to find great opportunities. One such opportunity as we previously announced our second largest acquisition to date Celtic Systems. Rick will share more. The Celtic is a perfect fit with our 2021 BIS acquisition. Celtic and BIS each have complementary best-of-class products for transportation departments at the state level. The cross-selling opportunities are compelling enough so we are better positioned to respond to RFPs. We can't wait to see how Celtic grows and landing this deal was an ideal start to fiscal year 2023.
Now I'll turn the call over to Clay, he will provide you more details on our financial quarter performance. Following Clay's comments, Rick will provide an update on some role changes and address M&A, and then we'll open up the call for questions.
Clay Whitson: Thanks, Greg. The following pertains to the fourth quarter of our fiscal year 2022, which is the quarter ended September 30, 2022. Please refer to the slide presentation titled Supplemental Information on our website for reference with this discussion. We had another great quarter with record revenues and adjusted EBITDA. Revenues for the fourth quarter increased 27% to $85.3 million from $67.2 million for Q4 2021, reflecting strong organic growth and acquisitions. Our revenue yield improved to 140 basis points for the quarter from 120 basis points for Q4 2021. Organic growth for this quarter was approximately 12%. Annual recurring revenues totaled $281.2 million for Q2 2022 compared to $210.8 million for Q4 2021, a growth rate of 33%.
Organic ARR growth generally runs a few percentage points above our total organic revenue growth. Over 80% of our revenues in the quarter came from recurring sources. Software and related services remain the largest portion of our revenues, representing 49% for fiscal 2022. Payments represented 45% and other just 6%. Adjusted EBITDA increased 27% to $21.7 million for Q4 2022 from $17.1 million for Q4 2021, reflecting continued momentum in our Software & Services segment. Adjusted EBITDA as a percentage of revenues increased to 25.5% for Q4 2022 from 25.4% for Q4 2021, reflecting margin improvement in our Software & Services segment. For the fiscal year, the adjusted EBITDA margin expanded 30 basis points to 25%. Pro forma adjusted diluted earnings per share increased to $0.39 for Q4 2022 from $0.33 for Q4 2021.
For the fiscal year 2022, pro forma adjusted diluted earnings per share increased to $1.48 from $1.05 for fiscal 2021. Again, please refer to the press release for a full description and reconciliation. Segment performance. Revenues in our Software & Services segment increased 40% to $51.8 million for Q4 2022 from $36.9 million for Q4 2021, principally reflecting growth in our two largest verticals, public sector and health care. Revenues in our Education vertical continued a strong rebound, increasing 35% Q4 to Q4, thanks to organic sales to new school districts and higher lunch and activity fees at existing districts. Federal and state subsidies for lunch have decreased significantly since the pandemic. Software license revenue increased 47% to $3.5 million for Q4 2022 from $2.4 million for Q4 2021.
The largest was an $800,000 image soft sale to a Department of Transportation in the Midwestern state for an enterprise document management system and workflow system. This line item made up only 3.5% of our total revenue in the quarter, but it has a 95% gross margin and can be lumpy and hard to predict, as you can see from the variation between quarters. While we are focused on SaaS and other recurring sources of revenue, license sales will not go away completely. Some customers, particularly in the public sector, still prefer them. The segment's adjusted EBITDA improved 55% to $17.1 million for Q4 2022 from $11.1 million for Q4 2021, outpacing revenues. The growth was principally driven by our two largest verticals, public sector and health care.
On a run rate basis, public sector represents over half of our consolidated business, while health care is an estimated 20%. Adjusted EBITDA as a percentage of revenues improved to 32.4% for Q4 2022 from 31.1% for Q4 2021, reflecting margin improvements in public sector and education. Revenues for our Merchant Services segment increased 9% to $33.4 million for Q4 2022 from $30.7 million for Q4 2021, principally reflecting growth in our B2B and ISO channels. Adjusted EBITDA for our Merchant Services segment increased slightly to $9.1 million for Q4 2022, with higher revenues, partially offset by higher residual expenses. In keeping with our strategy since the IPO, we have steadily redirected acquisition and internal resources from traditional Merchant Services into higher growth and higher margin software and services coupled with integrated payments.
Our balance sheet has allowed us to continue to execute our acquisition strategy. On September 30th, we have $181.5 million borrowed under our revolver net of cash under a $275 million facility. The face value of our convertible notes are $117 million. As of September 30th, our total leverage ratio was approximately 3.7 times, while the current constraint is 5.25 times. In conjunction with the Celtic Systems acquisition, we increased the size of our existing revolving credit facility from $275 million to $375 million. In October, we borrowed $85 million for the purchase of Celtic Systems, but we currently expect total leverage to be close to 4 times on December 31, 2022. The interest rate for the convertible notes is 1%, while the interest rate for the revolver is currently around 7%, but will increase as the Fed continues to raise rates.
Over time, we expect to convert roughly two thirds of adjusted EBITDA into free cash flow, which can be used for debt repayment, acquisitions, and earn-outs. We define free cash flow as adjusted EBITDA minus capital expenditures, internally capitalized software, cash interest, and cash taxes. Looking forward, the strong finish to our fiscal year gives us confidence in the following guidance for fiscal 2023. It excludes acquisitions that have not yet closed and transaction-related costs. Revenues, $360 million to $380 million; adjusted EBITDA, $94 million to $102 million; cash interest expense, $19 million to $22 million; pro forma adjusted diluted EPS, $1.50 to $1.62. From a seasonal standpoint, the Celtic Systems acquisition gives us a good start to the year like the October 1st healthcare acquisition did last year.
Acquisition activity could prove different this year, but we currently expect the quarters of fiscal 2023 to follow a similar pattern to those of fiscal 2022. As we become more software-centric, quarters might vary based upon perpetual license sales, even though our trend is generally toward more recurring revenue streams. I'll now turn the call over to Rick for company updates and M&A activity.

Rick Stanford: Thank you, Clay. Good morning, everyone. First, I want to speak a moment about our two new executive team members, Paul Christians and Chris Laisure. Since 2019 acquisition, Paul has been leading the Pace Payment business for us and also leading our public sector unified product offering, or UPO process with great success. We are proud to announce his promotion to Chief Operating Officer at i3 Verticals. In this new position, Paul will continue to oversee our public sector UPO strategy, and he will expand that successful effort to include leadership of UPO and Healthcare. I have no doubt that Paul will replicate the public sector successes within our Healthcare vertical. UPO is critical to our overall company strategy as we integrate products within our existing vertical businesses to provide comprehensive solutions to our customers.
Paul is a perfect fit for this role. Chris Laisure joined us as part of our BIS acquisition in early 2021. In his CEO role at BIS, Chris has led that business to impressive growth and has proven his deep understanding of the Public Sector vertical. He is now going to draw on that experience and will become the President of Public Sector, which is our largest vertical and is responsible for 50% of our revenues. Chris understands the ongoing needs of public sector customers across the country and will no doubt lead us to even more growth within that vertical. Paul and Chris are intelligent, seasoned, and effective leaders. Perhaps more importantly, they are quality individuals who will help encourage our high integrity, collaborative and entrepreneurial culture.
We look forward to their many contributions. Before I discuss M&A, I want to make note of developments within our Education businesses. As K-12 education market begins to shift to post-pandemic environment, prices on school lunches have increased across the board, while currently all federal and most state subsidies for lunches have decreased in most states. Districts are also seeing an uptick in other transactions as traditional activities resume, which adds to the daily student spend. These developments have contributed to increased revenues that we have seen in these businesses. I'll now speak to M&A. We continue to pursue growth by performing acquisitions of companies that fit with our strategy and emphasis on companies in our Public Sector and Healthcare verticals.
On October 4th, we announced our latest acquisition, the acquired business, Celtic Cross Holdings, Inc. and Celtic Systems Private Limited, together known as Celtic, fits extremely well with BIS. Both companies have products for transportation departments at the state level, but their products mostly complement each other. So we see many opportunities to expand the addressable market and cross-sell within existing customers. Celtic also offers a greater geographic reach with customers in 18 U.S. states and four Canadian provinces. Celtic software could be broken down into two parts, part one is motor carrier software. Late group fleet, vehicle and distance management capabilities are built in. In conjunction with their integrated inventory management module, it streamlines carrier credentialing and increases operational efficiencies through automated issuance.
It also has built-in tools for selecting carriers to audit based on specific auditor criteria, notifying carriers, and conducting both current and previous year carrier audits with end-to-end tracking capabilities. Their product gathers carrier and fuel-specific information, including miles traveled, gallons used, and taxes paid. It streamlines the oversized, overweight vehicle permitting process and automatically generates safe travel routes by evaluating and selecting the most appropriate route for specific vehicle and low dimensions, taking regulations, restrictions and roadway bridge hazards into account and provides turn-by-turn directions to the carrier. All of this resulting information provides the international rate plan, IRP, and International Fuel Tax Association, IFTA, offices with critical information that can be leveraged by carriers for registering, renewing and issuing credentials to carriers and vehicles.
It also provides roadside law enforcement assistance to quickly ascertain if a carrier and/or vehicle is in compliance with safety and credentialing rules, helping to keep unsafe vehicles off the road. Their supporting products include document management for electronic filing, management and retrieval of required documents. The software also allows for processing of mandatory quarterly tax returns, tax liability, including penalty interest fees and credits, and tax payment cutoff dates for various fuel types such as special fuels and dyed diesel fuels. It also provides for intrastate registrations for carrier fleets and other fleet types operating wholly within the jurisdiction while maintaining applicable insurance filings. Part two is motor vehicle software.
Some of the features include title transactions like original title, title transfer, title correction, etcetera. The software also provides for instruction permits, commercial and noncommercial driver's license, and identity card issuance. The software generates and tracks various types of driver credentials after analyzing driver records and history and collecting all the required document and fees. It captures and tracks all driver records, including convictions, points, accidents, and based on business rules, will automatically initiate the desired necessary actions such as sending a warning, generating suspension records, or reinstatement on suspension. It calculates and collects payments based on various business rules and distributes funds to appropriate general ledger accounts as required.
It manages dealer inventory and dealer licensing, which helps motor vehicle departments manage dealer permitting, dealer records, replications, audits and reporting. In summary, Celtic is a perfect fit in our Public Sector vertical. It aligns nicely with the combined BIS product suite and further enhances our presence in state and provincial level markets in the U.S. and Canada. In the past 30 days, both Celtic and BIS have been jointly responding to new RFPs currently in the market as well as joint marketing at state shows that have occurred. I want to specifically note that this deal fell within our normal range of multiples. Our pipeline remains robust with opportunities for acquisitions in Public Sector and Healthcare that are similar in size to many of our acquisitions today.
This concludes my comments, operator. At this time, we'll open the call for Q&A, please.
