Thank you, Oki, and hello everyone.

For our fiscal third quarter, we posted results that reflect the early stage of implementing our strategic growth plan. TradeStation aims to leverage its feature-rich technology and trading platform by investing in marketing and product enhancements that will accelerate the growth of customer accounts and customer assets under custody.

During the third fiscal quarter we continued to see strong account growth and growth in client assets. As of December 31, 2021, total accounts were 36% higher than at December 31, 2020, and TradeStation’s total customer assets under custody were $12.3 billion, 33% higher than December 31, 2020.

Cryptocurrency accounts grew to 9% of total accounts at December 31, 2021, from less than 2% at December 31, 2020. A significant contributor to this recent growth has been a promotional campaign that was launched late in the quarter and continues at this time. For this promotion, when the customer completes an approved crypto account application TradeStation makes the initial account funding for the customer -- a nominal amount of $10 BTC. We then engage with these new account holders with the goal of their making additional account deposits and investing and trading in crypto. This is an example of us deploying different marketing approaches to build our brand and increase customers on our platform.

Comparison of our trading activity in the third quarter to prior periods requires context for what occurred in the markets during our prior fiscal year, which was the first year of the COVID-19 pandemic. The markets experienced extreme volatility and unusually high levels of customer trading, and then returned toward pre-pandemic levels in our current fiscal year. Accordingly, our DARTs during the quarter declined by 10.2 percent compared to the prior-year third fiscal quarter. However, on a sequential quarter-over-quarter basis, which compares two periods in the lower volatility market, our DARTs increased by 5.6%.

Total brokerage and other commissions was $41.3 million in our third fiscal quarter. Even with the significant drop in volatility, as compared to the prior-year third fiscal quarter, we were able to drive an increase in trading-related revenue. This is primarily due to the growth of customer accounts.

Net interest income during the quarter grew 8.7% compared to the prior-year third fiscal quarter, driven mainly by an increase in securities lending revenue and margin lending revenue, partially offset by lower interest earned on customer cash and crypto asset lending.

Net interest income expanded by 26.3% quarter-over-quarter, driven primarily by a 31% increase in securities lending and strong growth in crypto asset lending. With respect to the portion of interest income we generate from investing customer cash, we anticipate benefitting in the next fiscal year from a rising interest-rate environment.

We continue to make progress on our plans to become a publicly-traded company listed on the New York Stock Exchange through a de-SPAC transaction, which we announced on November 4, 2021. Late in December 2021 we filed a registration statement on Form S-4 with the SEC and look forward to the completion of this transaction.

As I said at the beginning, we are in the investment phase of our growth strategy.

During the quarter, we increased our advertising spend in performance-based and brand marketing channels. This was a substantial, and planned, step-up that we expect to increase the size and pace of growth of our customer base.

We are also investing in our platform, and that is reflected in higher compensation and benefits expense. We are increasing software development headcount to deliver on several initiatives:

One is to support the evolution of our customer experience primarily across our website and mobile applications. This quarter we launched a new simplified portfolio and balances view in our Web App and Mobile Apps. Over the next several quarters, we look to further simplify our Web and Mobile experience and integrate crypto investing natively in our proprietary TradeStation apps. Another initiative is the expansion of our cryptocurrency brokerage offering. This quarter we launched support for trading crypto in an IRA account, our Crypto FIX API, , as well as support for the CME Micro ETH futures product. We also plan to increase the number of cryptocurrencies we support. Another area on which we are focused is to grow our strategic alliance business relationships by offering third-party fintech companies the ability, through our API technology, to enable their customers’ access to TradeStation’s brokerage services from their platforms. TradingView is the largest of our 70-plus strategic alliance relationships today, and we are further enhancing our API capabilities as we seek to scale this part of our business.

Thank you for your time, and we look forward to continuing to update you on the progress of these

initiatives. Oki . . .
