Exhibit 10.1

EXECUTION VERSION

AGREEMENT

This Agreement (this “Agreement”), dated as of February 17, 2019, is by and among Simcoe Capital Management, LLC (“Investor”), Donnelley Financial Solutions, Inc. (the “Company”), and, solely for purposes of Section 2(g) hereof, Jeffrey Jacobowitz (the “Investor Nominee”). In consideration of and reliance upon the mutual covenants and agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, Investor and the Company agree as follows:

1. Board Nomination and Other Company Matters.

(a) In accordance with the Company’s Amended and Restated By-Laws (“By-laws”) and Delaware law, the Company agrees that, at the meeting of the Board of Directors of the Company (the “Board”) on February 16, 2019, the Board will increase the size of the Board to nine members, effective at the 2019 annual meeting of the Company’s stockholders (the “2019 Annual Meeting”).

(b) The Company agrees that, provided that the Investor Nominee shall have completed and executed the Company’s Directors’ Questionnaire, agreed to comply with all current and future policies, procedures, codes, rules, standards, guidelines and confidentiality obligations applicable to all of the Company’s directors (or any applicable subset thereof), provided the information regarding himself that is required to be disclosed for candidates for directors and directors in a proxy statement under the federal securities laws of the United States of America and/or applicable New York Stock Exchange (“NYSE”) rules and regulations and provided such other customary information as reasonably requested by the Company:

i. at the 2019 Annual Meeting, the Board will nominate the Investor Nominee (other than in the case of the inability of such person to serve), together with the other persons included in the Company’s slate of nominees for election as director at the 2019 Annual Meeting in accordance with this Section 1(b), as directors of the Company, with a term expiring at the 2020 annual meeting of the Company’s stockholders (the “2020 Annual Meeting”);

ii. the Board will recommend that the stockholders of the Company vote to elect the Investor Nominee as director of the Company at the 2019 Annual Meeting;

iii. the Company will use its reasonable best efforts (which will include the solicitation of proxies) to obtain the election of the Investor Nominee at the 2019 Annual Meeting (it being understood that such efforts will be not less than the efforts used by the Company to obtain the election of any other independent (as determined under the listing rules of NYSE) director nominee nominated by it to serve as a director on the Board at the 2019 Annual Meeting); and

iv. if the Investor Nominee is elected as a director of the Company at the 2019 Annual Meeting, (a) at the 2020 Annual Meeting, the Board will nominate the Investor Nominee (other than in the case of the resignation, refusal or inability of such person to serve), together with the other persons included in the Company’s slate of nominees for election as director at the 2020 Annual Meeting in accordance with this Section 1(b), as directors of the Company, with a term expiring at the 2021 annual meeting of the Company’s stockholders (the “2021 Annual Meeting”); (b) the Board will recommend that the stockholders of the Company vote to elect the Investor Nominee as director of the Company at the 2020 Annual Meeting; and (c) the Company will use its reasonable best efforts (which will include the solicitation of proxies) to obtain the election of the Investor Nominee at the 2020 Annual Meeting (it being understood that such efforts will be not less than the efforts used by the Company to obtain the election of any other independent (as determined under the listing rules of NYSE) director nominee nominated by it to serve as a director on the Board at the 2020 Annual Meeting).

(c) Notwithstanding any of the foregoing, if at any time Investor ceases to beneficially own a “net long position” (as such term is defined in Rule 14e-4 of the Exchange Act, or the rules or regulations promulgated thereunder), of at least three percent (3%) of the outstanding shares of the common stock, par value $0.01 per share, of the Company (the “Company Common Stock”), subject to adjustment for stock splits, reclassifications, combinations and similar adjustments (the “Minimum Ownership Threshold”), the Investor Nominee will immediately offer his letter of resignation for consideration by the Board and all applicable committees and subcommittees thereof.

(d) During the period commencing with the date of this Agreement through the date of the 2019 Annual Meeting (the “Observer Period”), the Investor Nominee shall be a non-voting observer to the Board and shall receive copies of all documents relating to Board meetings distributed to the Board during the Observer Period, including notice of all meetings of the Board, all written consents executed by the Board, all materials prepared for consideration at any meeting of the Board, and all minutes related to each meeting of the Board contemporaneous with their distribution to the Board. The Investor Nominee shall be permitted to attend and reasonably participate, but not vote, at all meetings of the Board during the Observer Period (whether such meetings are held in person, telephonically or otherwise). Notwithstanding the foregoing, during the Observer Period, the Company reserves the right to exclude the Investor Nominee from access to any material or meeting or portion thereof if, and only to the extent that, the Board determines reasonably and in good faith that such exclusion is necessary or appropriate (including, without limitation, to preserve the attorney-client privilege, or avoid a conflict of interest). As a condition to serving as an observer, the Investor Nominee shall deliver to the Company (i) a written representation that such person will comply with all Company Policies (as defined below) and (ii) an executed confidentiality agreement in a form provided by the Company and to be agreed between Investor and the Company.

2. Investor Cooperation.

(a) Each of Investor and the Company agrees that, from the date of this Agreement until the earliest of (i) the date that is thirty (30) calendar days prior to any applicable deadline by which a stockholder must give notice to the Company of its intention to nominate a director for election at or bring other business before the 2021 Annual Meeting under the Company’s By-laws and (ii) any material breach of this Agreement by the Company (provided that the Company will have ten (10) business days following written notice from Investor of material breach to remedy such material breach if capable of remedy) (such period, the “Cooperation Period”), neither Investor nor the Company nor any of their respective agents, subsidiaries, affiliates, successors, assigns, officers, key employees or directors will, or will encourage any other person to, in any way publicly criticize, disparage, call into disrepute or otherwise defame or slander the other party or the other party’s subsidiaries, affiliates, successors, assigns, current or former officers, current or former directors, current or former employees, stockholders, agents or representatives or the other party’s businesses, products or services, including: (i) in any document or report filed with or furnished to the Securities and Exchange Commission (the “SEC”) or any other governmental agency, (ii) in any press release or other publicly available format or (iii) to any journalist or member of the media (including without limitation, in a television, radio, newspaper or magazine interview).

(b) The limitations set forth in Section 2(a) will not prevent Investor or the Company from responding to any public statement made by the other party of the nature described in Section 2(a) if such statement by the other party was made in breach of this Agreement.

(c) During the Cooperation Period, Investor will cause all shares of Company Common Stock beneficially owned, directly or indirectly, by it, or by any of its Affiliates or Associates, or any other securities of the Company for which Investor, or any of its Affiliates or Associates, has the right to vote, directly or indirectly, to be present in person or by proxy for quorum purposes and to be voted at any meeting of stockholders or at any adjournments or postponements thereof, and to consent in connection with any action by consent in lieu of a meeting, (i) in favor of each director nominated and recommended by the Board for election at any such meeting (including the Investor Nominee), (ii) against any stockholder nominations for director that are not approved and recommended by the Board for election at any such meeting and against any proposals or resolutions to remove any member of the Board and (iii) in accordance with recommendations by the Board on all other proposals or business not related to an Extraordinary Transaction (as defined below) that the Investor Nominee, in his capacity as a director of the Company, has voted against that may be the subject of stockholder action at such meetings; provided, however, that in the event both Institutional Shareholder Services Inc. (“ISS”) and Glass Lewis & Co., LLC (“Glass Lewis”) recommend otherwise with respect to the Company’s “say-on-pay” proposal, Investor shall be permitted to vote in accordance with the ISS and Glass Lewis recommendation.

4

vi. submit (publicly or otherwise) a proposal or request for, offer of (with or without conditions), or take any action in support of a proposal or request for, or offer of, any tender offer, exchange offer, merger, amalgamation, acquisition, recapitalization, consolidation, sale or acquisition of material assets, liquidation, dissolution or other extraordinary transaction involving the Company or any of its subsidiaries (each, an “Extraordinary Transaction”) or joint ventures or any of their respective securities, any material change in the capitalization, stock repurchase programs and practices, capital allocation programs and practices or dividend policy of the Company, any other material change in the Company’s business, any modifications to the Company’s Amended and Restated Certificate of Incorporation or By-laws, the delisting of a class of securities of the Company from any stock exchange or any action that would result in a class of securities of the Company to become eligible for termination of registration pursuant to Section 12(g)(4) of the Exchange Act, or take any action which would, or would reasonably be expected to, require public disclosure regarding any of the types of matters set forth in this clause (vi);

vii. encourage, assist or enter into any discussions, negotiations, arrangements or understandings with any person not a party to this Agreement (a “Third Party”) with respect to any of the foregoing, or otherwise form, join, encourage, influence, advise or in any way participate in any “group” (as such term is defined in Section 13(d)(3) of the Exchange Act) with respect to any securities of the Company or otherwise in any manner agree, attempt, seek or propose to deposit any securities of the Company in any voting trust or similar arrangement, or subject any securities of the Company to any agreement or arrangement with respect to the voting thereof (including by granting any proxy, consent or other authority to vote), except as expressly set forth in this Agreement;

viii. other than in Rule 144 open market broker sale transactions where the identity of the purchaser is not known and in underwritten widely dispersed public offerings, sell, offer or agree to sell directly or indirectly, through swap or hedging transactions or otherwise, the securities of the Company or any rights decoupled from the underlying securities of the Company held by Investor or any Investor Affiliate to a Third Party that, to Investor’s or the Investor Affiliate’s knowledge (after due inquiry in connection with a private, non-open-market transaction, it being understood that such knowledge will be deemed to exist with respect to any publicly available information, including information in documents filed with the SEC) would result in such Third Party (other than passive institutional investors reporting their beneficial ownership on Schedule 13G), together with its Affiliates and Associates, owning, controlling or otherwise having any beneficial or other ownership interest in the aggregate of more than 4.9% of the shares of the Company Common Stock outstanding at such time or would increase the beneficial or other ownership interest of any Third Party who, together with its Affiliates and Associates, has a beneficial or other ownership interest in the aggregate of more than 4.9% of the shares of the Company Common Stock outstanding at such time;
