Exhibit 99.1

New York, April 28, 2023 – Oppenheimer Holdings Inc. (NYSE: OPY) (the "Company" or "Firm") today reported net income of $14.6 million or $1.32 basic earnings per share for the first quarter of 2023, an increase of approximately 57.3%, compared with net income of $9.3 million or $0.75 basic earnings per share for the first quarter of 2022. Revenue for the first quarter of 2023 was $321.7 million, an increase of 20.9%, compared to revenue of $266.0 million for the first quarter of 2022.

Albert G. Lowenthal, Chairman and CEO commented, "The profitable results for the quarter reflect our ability to continue supporting and advising our clients and prudently managing our business in all types of markets. Due to a combination of macroeconomic factors and turmoil within the regional banking industry, the equity and fixed income markets were volatile during the first quarter of the year. Convinced that Federal Reserve ("FED") tightening would soon end, the equity markets rallied to start the year. However, unexpected bank failures created large uninsured bank deposit withdrawals at certain regional banks that led to the fear of a broader bank contagion. Early action by the regulators to provide liquidity to banks seems to have dramatically slowed the move of funds into money market funds and short-term government securities. While the Company did not have any direct exposures to the failed institutions, the events caused a reaction in equity and fixed income markets, impacted portfolio turnover and our transaction-based revenues. Rising interest rates and fear of a recession significantly limited issuers' access to capital, resulting in markedly lower investment banking revenues associated with new equity issuances and secondary offerings. Strong M&A advisory fees and trading revenues offset some of the weakness seen in the IPO market.

Private Client reported revenue for the current quarter of $203.4 million, 34.9% higher compared with a year ago mostly due to an increase in bank deposit sweep income and margin interest income driven by higher short-term interest rates. Pre-tax income of $54.5 million in the current quarter resulted in a pre-tax profit margin of 26.8%. Financial advisor headcount at the end of the current quarter was 959 compared to 993 at the end of the first quarter of 2022.

Asset Management reported revenue for the current quarter of $24.0 million, 11.6% lower compared with a year ago. Pre-tax income was $6.5 million, a decrease of 31.6% compared with the prior year period.

Capital Markets reported revenue for the current quarter of $90.3 million, 6.2% higher when compared with the prior year period. Pre-tax loss was $15.5 million compared with pre-tax income of $1.2 million a year ago.
