Thanks, Margi. Today, I will share additional details around our first quarter performance as well as provide our outlook for the second quarter and full year 2024. At a high level, I'll echo Marty's comments that it was a solid start to the year. Total revenue for the quarter was $306.1 million, up 19% year-over-year. Within our subscription business, revenue was $201.1 million, up 22% year-over-year. Total subscription pets increased 11% year-over-year to over 1,006,000 pets as of March 31. This includes approximately 43,000 pets in Europe, which are currently underwritten by third-party underwriters. Total monthly average revenue per pet for the quarter was $69.79 up 9.8% over the prior year period. The subscription business cost of paying veterinary invoices was $151.5 million, resulting in a value proposition of 75.3% and reflects a 225 basis point improvement over the prior year period. This improvement provides a clear representation of the actions we have taken to repair our margins, and we are pleased with this progress. Due to the seasonality of that pricing we highlighted earlier and last quarter, the cost of veterinary invoices as a percent of revenue increased 260 basis points from Q4.
Our target value proposition for our subscription business remains 71%, and we expect to close the gap to our target by year-end. As a percentage of subscription revenue, variable expenses were 9.6%, down from 10.1% a year ago. Fixed expenses as a percentage of revenue were 5.3%, up from 4.7% in the prior year period due to increases in our technology and G&A expenses, including additional expenses incurred related to the remediation of our material weaknesses. After the cost of paying veterinary invoices, variable expenses and fixed expenses, we calculate our adjusted operating income. Our subscription business delivered adjusted operating income of $19.6 million, an increase of 55% from last year. Subscription adjusted operating margin was 9.7% of subscription revenue. This is up from 7.6% in the prior year quarter and represents approximately 210 basis points of year-over-year margin expansion. Now I'll turn to our other business segment, which is comprised of revenue from our other products and services that generally have a B2B component and a different margin profile than our subscription business.
Our other business revenue was $105 million for the quarter, an increase of 15% year-over-year. Adjusted operating income for this segment was $1.7 million, a decrease of 41% from last year. The decrease was driven by the previously mentioned increase in fixed expenses and a lower gross margin. In total, adjusted operating income was $21.3 million in Q1, in line with our expectations. This was up 37% from Q1 last year, but down 22% from Q4. In Q1, our higher-value subscription business comprised approximately 92% of our adjusted operating income in the quarter. This is up from 84% for the full year in 2023. We expect this trend to continue as one of our partners in our other business, Pets Best, continues to enroll pets with their new underwriter. During the quarter, we deployed $15 million to acquire approximately 67,200 new subscription pets. Excluding the approximate 3,900 new European bets that are underwritten by a third party, this translated into an average pet acquisition cost of $207 per pet in the quarter, down from $247 in the prior year period and $217 in Q4.
We also invested $1.2 million in the quarter in development costs. Stock-based compensation expense was $7.4 million during the quarter. As a result, net loss was $6.9 million or a loss of $0.16 per basic and diluted share compared to a loss of $24.8 million or a loss of $0.60 per basic and diluted share in the prior year period. In terms of cash flow, operating cash flow was $2.4 million in the quarter compared to a negative $6.9 million in the prior year period. Capital expenditures totaled $3.1 million. As a result, free cash flow was a negative $0.6 million, an $11.4 million improvement from the prior year's first quarter. Similar to our AOI, our free cash flow is impacted by the seasonal fluctuations we have discussed. It is for this reason, we have set an annual free cash flow target at 2.5% of revenue. We believe this is a prudent amount given the strength of our capital position and our desire to grow in such a large underpenetrated global market. Turning to the balance sheet. We ended the quarter with $275.2 million in cash and short-term investments. Outside of our insurance entities, we held $38.1 million in cash and short-term investments with an additional $15 million available under our credit facility.
At the end of the quarter, we maintained $256.7 million of capital surplus at our insurance subsidiaries, which was $103.4 million more than the estimated risk-based capital requirement of $153.3 million. This is down from our year-end requirements as growth in our other business slows and the capital intensity of our business is lowered. Last quarter, we reported 2 material weaknesses as a result of the 2023 audit. In response to this, we have made investments in internal controls, technology and SOX compliance. We have also hired PwC to assist us in the remediation of these material weaknesses and we are making progress in addressing these deficiencies. We will look to regain more efficiency in our fixed expenses throughout the year while balancing our continued remediation efforts in earnest. I'll now turn to our outlook. We are updating our full year revenue guidance, which is now expected to be in the range of $1.244 billion to $1.276 billion or 14% growth at the midpoint. This takes into account our slight overperformance in Q1. We continue to expect to grow subscription revenue in the range of $842 million to $862 million, representing 20% year-over-year growth at the midpoint.
We also continue to expect total adjusted operating income to be in the range of $100 million to $120 million or 32% year-over-year growth at the midpoint. As we think about the shape of the year, we expect that the first half of the year will start from a lower margin standpoint within our subscription business and build back to a 15% adjusted operating margin by Q4 of this year. Second, for the second quarter of 2024, total revenues are expected to be in the range of $306 million to $311 million, representing 14% year-over-year growth at the midpoint. Subscription revenue is expected to be in the range of $206 million to $208 million or 20% year-over-year growth at the midpoint. Total adjusted operating income is expected to be in the range of $21 million to $23 million. As a reminder, our revenue projections are subject to conversion rate movements predominantly between the U.S. and Canadian currencies. For the second quarter and full year of 2024, we used a 74% conversion rate in our projections, which was the approximate rate at the end of March. With that, I'll hand it back to Margi.
