(“Acquisition Sub”). Under the terms of the Merger Agreement, Acquisition Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a direct or indirect wholly owned subsidiary of Parent.

Pursuant to the terms of the Merger Agreement, Parent is responsible for (i) paying all fees and expenses the Company incurs in connection with the Consent Solicitations and (ii) indemnifying the Company from and against any and all losses the Company incurs in connection with the Consent Solicitations.

Use of Forward-Looking Statements

This communication includes certain “forward-looking statements” within the meaning of, and subject to the safe harbor created by, the federal securities laws, including statements related to the proposed Merger. These forward-looking statements are based on the Company’s current expectations, estimates and projections regarding, among other things, the expected date of closing of the Merger and the potential benefits thereof, its business and industry, management’s beliefs and certain assumptions made by the Company, all of which are subject to change. Forward-looking statements often contain words such as “expect,” “anticipate,” “intend,” “aims,” “plan,” “believe,” “could,” “seek,” “see,” “will,” “may,” “would,” “might,” “considered,” “potential,” “estimate,” “continue,” “likely,” “target” or similar expressions or the negatives of these words or other comparable terminology that convey uncertainty of future events or outcomes. By their nature, forward-looking statements address matters that involve risks and uncertainties because they relate to events and depend upon future circumstances that may or may not occur, such as the consummation of the Merger and the anticipated benefits thereof. These and other forward-looking statements are not guarantees of future results and are subject to risks, uncertainties and assumptions that could cause actual results to differ materially from those expressed in any forward-looking statements. Important risk factors that may cause such a difference include (i) impediments to the completion of the Merger on anticipated terms and timing, including obtaining required stockholder and regulatory approvals and the satisfaction of other conditions to the completion of the Merger; (ii) significant transaction costs associated with the Merger; (iii) potential litigation relating to the Merger, including the effects of any outcomes related thereto; (iv) the risk that disruptions from the Merger will harm the Company’s business, including current plans and operations; (v) the ability of the Company to retain and hire key personnel; (vi) potential adverse reactions or changes to business relationships resulting from the announcement or completion of the Merger; (vii) legislative, regulatory and economic developments affecting the Company’s business; (viii) general economic and market developments and conditions; (ix) the evolving legal, regulatory and tax regimes under which the Company operates; (x) potential business uncertainty, including changes to existing business relationships, during the pendency of the Merger that could affect the Company’s financial performance; (xi) certain restrictions during the pendency of the Merger that may impact the Company’s ability to pursue certain business opportunities or strategic transactions; (xii) continued availability of capital and financing and rating agency actions; (xiii) the ability of affiliates of Chatham Asset Management, LLC to obtain the necessary financing arrangements set forth in the commitment letters received in connection with the Merger; (xiv) the

occurrence of any event, change or other circumstance that could give rise to the termination of the Merger, including in circumstances requiring the Company to pay expense reimbursements to affiliates of Chatham Asset Management, LLC under the Merger Agreement; (xv) unpredictability and severity of catastrophic events, including acts of terrorism, outbreak of war or hostilities, civil unrest, adverse climate or weather events or the COVID-19 pandemic or other public health emergencies, as well as the Company’s response to any of the aforementioned factors; (xvi) competitive responses to the Merger; (xvii) the risks and uncertainties pertaining to the Company’s business, including those detailed under the heading “Risk Factors” and elsewhere in the Company’s public filings with the U.S. Securities and Exchange Commission (the “SEC”); and (xviii) the risks and uncertainties described in the proxy statement filed in connection with the Merger and available from the sources indicated below (the “Proxy Statement”). These risks, as well as other risks associated with the Merger are more fully discussed in the Proxy Statement. While the list of factors presented here is, and the list of factors presented in the Proxy Statement are, considered representative, no such list should be considered to be a complete statement of all risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material impact on the Company’s financial condition, results of operations, credit rating or liquidity or ability to consummate the Merger. These forward-looking statements speak only as of the date they are made, and the Company does not undertake to and disclaims any obligation to publicly release the results of any updates or revisions to these forward-looking statements that may be made to reflect future events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.

Exhibit 99.1

RRD ANNOUNCES EXPIRATION OF ITS CONSENT SOLICITATIONS FOR ITS 2024 NOTES, 2026 NOTES AND 2031 DEBENTURES AND EXTENSION OF ITS CONSENT SOLICITATIONS FOR ITS 2023 NOTES AND 2029 DEBENTURES

CHICAGO, Illinois, February 2, 2022 — R.R. Donnelley & Sons Company (NYSE: RRD) (“RRD” or the “Company”) today announced the expiration of its previously announced solicitation of waivers and consents (the “Consent Solicitations”) from holders of its 6.000% Notes due 2024 (the “2024 Notes”), 6.125% Senior Secured Notes due 2026 (the “2026 Notes”) and 8.820% Debentures due 2031 (the “2031 Debentures”) to waive certain provisions in and adopt certain proposed amendments to each of the indentures governing the 2024 Notes (the “2024 Notes Indentures”), the 2026 Notes (the “2026 Notes Indenture”) and the 2031 Debentures (the “2031 Debentures Indenture”), including with respect to:

The Consent Solicitations are subject to the terms and conditions set forth in the consent solicitation statement, dated January 20, 2022 (the “Consent Solicitation Statement”). The Consent Solicitations with respect to the 2024 Notes, the 2026 Notes and the 2031 Debentures expired at 5:00 p.m., New York City time, on February 1, 2022 (the “Expiration Date”). As of the Expiration Date, registered holders of the 2024 Notes, the 2026 Notes and the 2031 Debentures holding an aggregate principal amount of such series as identified in the table below, validly delivered and did not validly withdraw their consents to the Proposed Amendments (the “Consents”).

The Company has accepted all Consents relating to the 2024 Notes, the 2026 Notes and the 2031 Debentures that were validly delivered and not validly withdrawn prior to the Expiration Date. The Consent Solicitations for the 2024 Notes, the 2026 Notes and the 2031 Debentures expired at the Expiration Date, and Consents with respect to such series may no longer be withdrawn.

A supplemental indenture giving effect to the Proposed Amendments with respect to the 2024 Notes, the 2026 Notes and the 2031 Debentures will be executed promptly. Upon its execution, each supplemental indenture will be effective and constitute a binding agreement between the Company, the guarantors (where applicable) and the applicable trustee. However, the Proposed Amendments will not become operative until immediately prior to the consummation of the Merger and will cease to be operative if the Merger is not consummated or, with respect to the 2024 Notes and 2031 Debentures, the consent consideration is not paid to the holders thereof that validly delivered and did not revoke such Consents.

The effectiveness of the Proposed Amendments is not a condition to the consummation of the Merger or other transactions contemplated by the Merger Agreement, but the consummation of the Merger is a condition to the Supplemental Indentures becoming operative. Based on the information currently available to the Company, it is expected that the Merger will be consummated during the first quarter of 2022; however, there is no assurance that the Merger will be consummated in the first quarter of 2022 or at any time prior to the Termination Date (as defined in the Merger Agreement) (which is subject to extension under certain limited circumstances as described in the Consent Solicitation Statement).

In addition, the Company is extending the previously announced expiration date for the Consent Solicitations from holders of the Company’s 6.500% Notes due 2023 (the “2023 Notes”) and 6.625% Debentures due 2029 (the “2029 Debentures” and, collectively with the 2024 Notes, the 2026 Notes and the 2031 Debentures, the “Debt Securities”) to waive certain provisions in and adopt certain proposed amendments to each of the indentures governing the 2023 Notes and the 2029 Debentures. The new expiration date for validly delivering Consents with respect to the 2023 Notes and the 2029 Debentures has been extended from 5:00 p.m., New York City time, on February 1, 2022 to 5:00 p.m., New York City time, on February 4, 2022, and is subject to further extension by the Company in its sole discretion.

The Consent Solicitations and the extension and modification thereof were made at the request of Chatham Delta Parent, Inc. (“Parent”) pursuant to the terms of the previously announced Agreement and Plan of Merger (the “Merger Agreement”) entered into on December 14, 2021 by and among the Company, Parent and Chatham Delta Acquisition Sub, Inc. (“Acquisition Sub”). Under the terms of the Merger Agreement, Acquisition Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a direct or indirect wholly owned subsidiary of Parent.

The Company, at the request of Parent, has engaged Jefferies LLC to act as solicitation agent (“Solicitation Agent”) in connection with the Consent Solicitations. Questions regarding the Consent Solicitation may be directed to the Solicitation Agent at the following address or telephone number: Jefferies LLC, 520 Madison Avenue, New York, NY 10022, Attn: Scott Peloso, (212) 284-3426. The Company, at the request of Parent, has engaged Ipreo LLC to act as information and tabulation agent (the “Information and Tabulation Agent”). Requests for documents relating to the Consent Solicitations may be obtained by contacting Ipreo LLC at (888) 593-9546 (U.S. toll-free) or (212) 849-3880 (banks and brokers) or ipreo-consentSolicitation@ihsmarkit.com.

This news release does not constitute a solicitation of consents with respect to the Debt Securities, and consent solicitations with respect to the Debt Securities are only being made pursuant to the terms of the Consent Solicitation Statement. Consent solicitations are not being made to, and consents are not being solicited from, holders of Debt Securities in any jurisdiction in which it is unlawful to make such consent solicitations or grant such consent. None of the Company, the trustees, the Solicitation Agent or the Information and Tabulation Agent makes any recommendation as to whether or not holders should deliver consents with respect to the Debt Securities. Each holder must make its own decision as to whether or not to deliver consents.

Use of Forward-Looking Statements

This news release includes certain “forward-looking statements” within the meaning of, and subject to the safe harbor created by, the federal securities laws, including statements related to the proposed Merger. These forward-looking statements are based on the Company’s current expectations, estimates and projections regarding, among other things, the expected date of closing of the Merger and the potential benefits thereof, its business and industry, management’s beliefs and certain assumptions made by the Company, all of which are subject to change. Forward-looking statements often contain words such as “expect,” “anticipate,” “intend,” “aims,” “plan,” “believe,” “could,” “seek,” “see,” “will,” “may,” “would,” “might,” “considered,” “potential,” “estimate,” “continue,” “likely,” “target” or similar expressions or the negatives of these words or other comparable terminology that convey uncertainty of future events or outcomes. By their nature, forward-looking statements address matters that involve risks and uncertainties because they relate to events and depend upon future circumstances that may or may not occur, such as the consummation of the Merger and the anticipated benefits thereof. These and other forward-looking statements are not guarantees of future results and are subject to risks, uncertainties and assumptions that could cause actual results to differ materially from those expressed in any forward-looking statements. Important risk factors that may cause such a difference include (i) impediments to the completion of the Merger on anticipated terms and timing, including obtaining required stockholder and regulatory approvals and the satisfaction of other conditions to the completion of the Merger; (ii) significant transaction costs associated with the Merger; (iii) potential litigation relating to the Merger, including the effects of any outcomes related thereto; (iv) the risk that disruptions from the Merger will harm the Company’s business, including current plans and operations; (v) the ability of the Company to retain and hire key personnel; (vi) potential adverse reactions or changes to business relationships resulting from the announcement or completion of the Merger; (vii) legislative, regulatory and economic developments affecting the Company’s business; (viii) general economic and market developments and conditions; (ix) the evolving legal, regulatory and tax regimes under which the Company operates; (x) potential business uncertainty, including changes to existing business relationships, during the pendency of the Merger that could affect the Company’s financial performance; (xi) certain restrictions during the pendency of the Merger that may impact the Company’s ability to pursue certain business opportunities or strategic transactions; (xii) continued availability of capital and financing and rating agency actions; (xiii) the ability of affiliates of Chatham Asset Management, LLC to obtain the necessary financing arrangements set forth in the commitment letters received in connection with the Merger; (xiv) the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger, including in circumstances requiring the Company to pay expense reimbursements to affiliates of Chatham Asset

Management, LLC under the Merger Agreement; (xv) unpredictability and severity of catastrophic events, including acts of terrorism, outbreak of war or hostilities, civil unrest, adverse climate or weather events or the COVID-19 pandemic or other public health emergencies, as well as the Company’s response to any of the aforementioned factors; (xvi) competitive responses to the Merger; (xvii) the risks and uncertainties pertaining to the Company’s business, including those detailed under the heading “Risk Factors” and elsewhere in the Company’s public filings with the U.S. Securities and Exchange Commission (the “SEC”); and (xviii) the risks and uncertainties described in the proxy statement filed in connection with the Merger and available from the sources indicated below (the “Proxy Statement”). These risks, as well as other risks associated with the Merger are more fully discussed in the Proxy Statement. While the list of factors presented here is, and the list of factors presented in the Proxy Statement are, considered representative, no such list should be considered to be a complete statement of all risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material impact on the Company’s financial condition, results of operations, credit rating or liquidity or ability to consummate the Merger. These forward-looking statements speak only as of the date they are made, and the Company does not undertake to and disclaims any obligation to publicly release the results of any updates or revisions to these forward-looking statements that may be made to reflect future events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.
