Thank you, Yinghua. Total first quarter revenues of $1.2 million were essentially flat from the fourth quarter of 2022 and down from $2.4 million for the first quarter of '22. The year-over-year decline is primarily attributable to the timing of our original content series, ELEVATED. Season 1, which consisted of 4 episodes, was launched and entirely recognized in the first quarter of 2022. Season 2 with 10 episodes will be distributed and recognized in full in the second quarter of 2023. This timing issue was partially offset by a 9.5% year-over-year increase in revenues from proprietary and third-party events held at the company's HyperX Arena Las Vegas and in our Allied Esports Truck operations.
Total costs and expenses for the first quarter of 2023 were $3.8 million, a decrease of $2.3 million or 38% compared to the first quarter of 2022. Costs and expenses decreased in large part to the timing and accounting expense recognition of ELEVATED as well as a 26% reduction in our general and administrative expenses, principally cash, severance and stock-based compensation.
Net loss for the first quarter of 2023 was $1.9 million compared to a net loss of $3.8 million in the prior year period. Our results for Q1 2023 included approximately $734,000 of interest income earned on short-term investments.
Adjusted EBITDA loss was $2 million for the first quarter of 2023, a 20% reduction as compared with a loss of $2.5 million in Q1 2022. Our adjusted EBITDA includes adjustments for depreciation, amortization, stock-based compensation and interest income.
Now moving on to our balance sheet. As of March 31, 2023, our cash and short-term investments position totaled $84.4 million, including $5 million of restricted cash, compared to $86.8 million at December 31, 2022, which also included $5 million of restricted cash. As of March 31, 2023, the company's working capital position was $75.6 million, including the current portion of an operating lease liability of $1.3 million that was recorded in connection with the implementation of the new leasing standard, ASC 842, on December 31, 2022.
Also during the quarter and under our stock repurchase program, we acquired 1,105,604 shares of our common stock in open-market transactions at an average selling price of $1.26 for a total repurchase cost of $1.43 million, excluding broker fees. This brings us to a total of $2.02 million in repurchases since the commencement of the plan. Moving forward, the manner, timing and amount of any purchases will continue to be based on an evaluation of market conditions, stock price, and other factors.
Overall, it was a solid quarter at Allied, and we are trending well so far in Q2 as we begin recognizing revenue from Season 2 of ELEVATED and continue moving forward on our strategic plan.
I will now turn the call back over to Yinghua for closing remarks.
