The Board of Directors of BlackRock Corporate High Yield Fund, Inc. (NYSE: HYT, CUSIP: 09255P107) (the “Fund”) today announced the early declaration of a regular monthly distribution for October.

Declaration- 9/8/2022 Ex-Date- 10/4/2022 Record- 10/5/2022 Payable-10/31/2022

* In order to comply with the requirements of Section 19 of the Investment Company Act of 1940, as amended (the “1940 Act”), the Fund posted to the DTC bulletin board and sent to its shareholders of record as of the applicable record date a Section 19 notice with the previous distribution payment. The Section 19 notice was provided for informational purposes only and not for tax reporting purposes. This information can be found in the “Closed-End Funds” section of www.blackrock.com. As applicable, the final determination of the source and tax characteristics of all distributions in 2022 will be made after the end of the year.

The Fund has adopted a managed distribution plan (the “Plan”). The fixed amounts distributed per share are subject to change at the discretion of the Fund’s Board of Directors. Under the Plan, the Fund will distribute all available investment income to its shareholders, consistent with its primary investment objectives and as required by the Internal Revenue Code of 1986, as amended (the “Code”). If sufficient investment income is not available on a monthly basis, the Fund will distribute long-term capital gains and/or return capital to its shareholders in order to maintain a level distribution.

The estimated sources of the Fund’s distribution as of September 8, 2022, which does not include the upcoming September 14, 2022 Ex-Date, and for its current fiscal year are as follows:

The amounts and sources of distributions reported are only estimates and are not provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon the Fund’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.

Shareholders should not draw any conclusions about the Fund’s investment performance from the amount of the Fund’s current distributions or from the terms of the Plan.

The amount distributed per share under the Plan is subject to change at the discretion of the Fund’s Board. The Plan will be subject to ongoing review by the Board to determine whether the Plan should be continued, modified or terminated. The Board may amend the terms of the Plan or suspend or terminate the Plan at any time without prior notice to the Fund’s shareholders if it deems such actions to be in the best interest of the Fund or its shareholders. The amendment or termination of the Plan could have an adverse effect on the market price of the Fund’s shares.
