Starboard Value and Opportunity Master Fund Ltd

_____________, 2020

Dear Fellow GCP Stockholders:

Starboard Value and Opportunity Master Fund Ltd (together with its affiliates, “Starboard” or “we”) and the other participants in this solicitation are the beneficial owners of an aggregate of 5,952,089 shares, or approximately 8.2% of the outstanding common stock, par value $0.01 per share (the “Common Stock”) of GCP Applied Technologies Inc., a Delaware corporation (“GCP” or the “Company”), making us one of the Company’s largest stockholders. For the reasons set forth in the attached Proxy Statement, we believe significant changes to the composition of the Board of Directors of the Company (the “Board”) are necessary in order to ensure that the Company is being run in a manner consistent with your best interests. We have nominated a slate of nine (9) highly-qualified director candidates for election to the Board at the Company’s upcoming 2020 annual meeting of stockholders (the “Annual Meeting”).

GCP is fundamentally a great company with a strong product portfolio and end market positioning, however, we believe it remains deeply undervalued with opportunities to unlock significant value within the control of management and the Board. Despite the Company’s promising future prospects, GCP has suffered from a prolonged period of disappointing operating and financial results, poor corporate governance and troubling compensation practices. It has now been over a year since we first highlighted our serious concerns to the Company and yet not nearly enough has been done to address these issues.

Despite our efforts to engage constructively with the Company, including by reaching an agreement on the appointment of two new independent and highly-qualified director candidates last year, very little progress has been made to put GCP on a better path. It has therefore become clear to us that additional and substantial change on the Board is required to drive the much needed change at GCP and to provide renewed accountability to stockholders.

We believe that GCP needs a new plan, with improved execution and greatly enhanced Board oversight. Starboard has significant experience in these areas with a long, successful track record of driving operational, financial, strategic, and governance changes that benefit employees, customers, and stockholders. We firmly believe that with the right Board in place, GCP can be a best-in-class company in its industry and generate significant value for all stockholders. We are therefore seeking to reconstitute the Board with directors who we believe have appropriate and relevant skill sets, as well as the shared objective of enhancing value for the benefit of all GCP stockholders.

The nine (9) director candidates we have nominated - Kevin W. Brown, Peter A. Feld, Janet P. Giesselman, Clay H. Kiefaber, Gavin T. Molinelli, Marran H. Ogilvie, Andrew M. Ross, Linda J. Welty and Robert H. Yanker - have deeply relevant backgrounds to GCP’s business and current challenges, including backgrounds spanning operations, finance, private equity, mergers and acquisitions, restructuring, strategic transformation, and public company governance. As a group, they have substantial and highly successful experience in the chemical, construction, and broader industrial industries and collectively have decades of experience as CEOs, senior executives, chairmen and directors of well-performing industrial companies.

We acknowledge that Mr. Kiefaber and Ms. Ogilvie currently serve on the Board, with terms expiring at the Annual Meeting. While the Company has not yet announced its slate of nominees for the Annual Meeting, we would expect the Company to nominate Mr. Kiefaber and Ms. Ogilvie for re-election to the Board at the Annual Meeting given their strong backgrounds and expertise and understand that each of Mr. Kiefaber and Ms. Ogilvie will consent to being named and shall be deemed a participant in the Company’s proxy materials in such event. Nonetheless, we believe Mr. Kiefaber’s and Ms. Ogilvie’s continued presence on the Board is essential and in the best interest of all stockholders, and we have obtained their consent to being named in this Proxy Statement as our nominees for election at the Annual Meeting in order to ensure their re-election to the Board.

We are mindful that replacing a substantial portion or a majority of an incumbent board of directors represents an extraordinary step, and we take that responsibility very seriously. In the past, we have had tremendous success in similar situations that resulted in a change in a majority of a board. Two examples of such situations, among others, are Darden Restaurants, Inc. (“Darden”) and Marvell Technology Group Ltd (“Marvell”).

At Darden, stockholders voted to replace the entire board of directors with twelve new board members nominated by Starboard. This new board, along with the new management team, subsequently implemented and oversaw a highly successful turnaround that repositioned Darden and unlocked tremendous stockholder value through a combination of accelerated organic revenue growth, improved margins and cash flow generation, and the separation of non-core assets. Since Darden’s board of directors was entirely refreshed in October 2014, its share price is up over 150%, excluding the additional returns from the spin-off of Darden’s real estate assets.

In the case of Marvell, Starboard was instrumental in creating a majority change in the composition of the board of directors, following which the new board hired a new management team and oversaw an incredibly successful turnaround that focused on improving organic revenue growth and operating profit while reducing operating expenditures. Since the time Marvell reached a settlement with Starboard in April 2016, revenue growth, gross margins, and operating margins have all improved substantially, which has led to significant stockholder value creation. Marvell’s stock price has appreciated over 130% since Starboard’s settlement in April 2016.

In each of these situations, no more than two direct representatives of Starboard were added to the board of directors, and the vast majority of the board was comprised of independent directors who shared a common goal of driving significant value creation at each of these companies.  

As with each of Darden and Marvell, we currently view GCP as having the potential to achieve tremendous improvement in financial, operational, and stock-price performance under the guidance of a newly constituted and highly-esteemed Board committed to serving the best interests of all stockholders.

If elected, our nominees, subject to their fiduciary duties, are committed to implementing a comprehensive turnaround plan aimed at unlocking the full potential of GCP. We look forward to publicly releasing a comprehensive turnaround plan over the coming weeks and months. While we have confidence that our director nominees’ plans for GCP will put the Company on the right path towards substantial stockholder value creation, there can be no assurance that the implementation of this comprehensive turnaround plan will ultimately enhance stockholder value. In the event that our director nominees comprise less than a majority of the Board following the Annual Meeting, there can be no assurance that any actions or changes proposed by our director nominees, including the implementation of any turnaround plan, will be adopted or supported by the Board.

There are currently nine (9) directors serving on the Board, all of whom have terms expiring at the Annual Meeting.¹ Through the attached Proxy Statement and enclosed WHITE proxy card, we are soliciting proxies to elect only our nine (9) nominees. Accordingly, the enclosed WHITE proxy card may only be voted for our nominees and does not confer voting power with respect to any of the Company’s director nominees. You can only vote for the Company’s director nominees by signing and returning a proxy card provided by the Company. Stockholders should refer to the Company’s proxy statement for the names, backgrounds, qualifications and other information concerning the Company’s nominees.

¹ The Company has not yet announced its nominees for election at the Annual Meeting, including whether it will re-nominate Mr. Kiefaber and Ms. Ogilvie, or whether it will fill the vacancy created due to Gregory Poling’s retirement from the Board, effective December 31, 2019, thereby maintaining its prior Board size of ten (10) directors. Once the Company announces its nominees and the number of seats up for election at the Annual Meeting, Starboard will make any necessary updates to this cover letter and the attached Proxy Statement.

We urge you to carefully consider the information contained in the attached Proxy Statement and then support our efforts by signing, dating, and returning the enclosed WHITE proxy card today. The attached Proxy Statement and the enclosed WHITE proxy card are first being furnished to the stockholders on or about ___________, 2020.

We are seeking your support at the Company’s 2020 Annual Meeting of Stockholders, scheduled to be held on ____________, 2020 at _______ Eastern Time at _____________________ (including any adjournments or postponements thereof and any meeting which may be called in lieu thereof, the “Annual Meeting”), for the following purposes²:

This Proxy Statement and the enclosed WHITE proxy card are first being furnished to stockholders on or about [___________], 2020.

While we currently intend to vote all of the Starboard Group Shares in favor of the election of the Nominees, we reserve the right to vote some or all of the Starboard Group Shares for some or all of the Company’s director nominees, as we see fit, in order to achieve a Board composition that we believe is in the best interest of all stockholders. We would only intend to vote some or all of the Starboard Group Shares for some or all of the Company’s director nominees in the event it were to become apparent to us, based on the projected voting results at such time, that by voting the Starboard Group Shares we could help elect the Company nominee(s) that we believe are the most qualified to serve as directors and thus help achieve a Board composition that we believe is in the best interest of all stockholders. Stockholders should understand, however, that all shares of Common Stock represented by the enclosed WHITE proxy card will be voted at the Annual Meeting as marked.

· On February 27, 2019, the Company issued a press release including an open letter to stockholders notifying them of the Company’s decision to initiate a comprehensive review of strategic, financial and operational opportunities.

REASONS FOR THE SOLICITATION

WE BELIEVE THE TIME FOR SUBSTANTIAL CHANGE IS NOW

We believe that GCP is deeply undervalued and that significant opportunities exist within the control of management and the Board to unlock substantial value for all stockholders. Unfortunately, we do not have confidence that the Board, as currently composed, will take the necessary steps to reverse the Company’s prolonged underperformance and maximize opportunities for value creation.

We invested in the Company because we believe that GCP has a strong product portfolio with differentiated capabilities and strong end market positioning. Furthermore, our research indicates that the Company has significant opportunities to improve revenue trends, operating margins, and free cash flow generation. However, despite this untapped potential, GCP has suffered from a prolonged period of disappointing operating and financial results, poor corporate governance and excessive executive compensation.

It has now been over a year since we first highlighted our serious concerns to the Board. Unfortunately, despite our prior and continued efforts to engage constructively with the Company, very little progress has been made to put GCP on a better path. Although we were pleased to reach an agreement on the appointment of two new independent and highly-qualified director candidates last year - Mr. Kiefaber and Ms. Ogilvie - who we continue to believe add tremendous value to the Board, it has become clear to us that additional and more substantial change on the Board is required to address the very serious issues plaguing the Company and to ensure that the interests of stockholders are appropriately represented in the boardroom.

We are therefore soliciting your support at the Annual Meeting to elect our highly-qualified Nominees, who we believe would bring significant and relevant experience to the Board along with a commitment to develop and implement a strategic plan to realize GCP’s potential. Our Nominees were carefully selected and possess skill sets in areas directly relevant to GCP’s business and its current challenges and opportunities.

The Board Has Overseen Tremendous Value Destruction Since GCP’s Spin-Off from W.R. Grace

Since the Company’s spin-off from W.R. Grace & Co. on February 3, 2016, GCP has drastically underperformed the overall market and its main competitors.

10

We believe a reconstituted Board is required to provide effective oversight of management, instill accountability in the boardroom and ensure actions are taken to reverse this troubling history of underperformance.

11

We Believe Operational Missteps Have Led to Significant Margin Degradation at GCP

GCP has produced extremely poor results over a prolonged period of time. As shown in the following chart, GCP’s adjusted EBIT margins have declined significantly since 2015, driven by weaknesses across both of the Company’s operating segments. This compares to a healthy backdrop for the broader industry. In fact, most peers over this timeframe have fared significantly better than GCP resulting in the margin gap widening to its highest level since GCP became an independent public company in 2016.

 

12

These poor results occurred despite management’s consistent promises to the contrary.

 

We believe these margin issues are driven in part by a bloated SG&A cost structure and unfortunately, minimal progress has been made to address these inefficiencies. Despite historical actions and slightly higher total revenue, SG&A as a percentage of revenue continues to be substantially higher than management’s target and significantly higher than peers.

13

We believe the elevated SG&A expense is the result of significant execution issues across both of GCP’s operating segments - the Specialty Construction Chemicals (“SCC”) segment and the Specialty Building Materials (“SBM”) segment. As shown below, the Company has failed to gain SG&A leverage despite years of supposed progress and numerous restructuring programs. Specifically, the SCC segment was burdened with excess SG&A due to GCP’s historical expansion into unprofitable geographies, a strategy which is now being reversed. Within the SBM segment, we believe that the business was not given the proper oversight and investment, which is now manifesting itself in terms of product gaps and increased market competitiveness. In addition, the Company was late to react to changes in the marketplace and readjust its cost structure to adapt to current market conditions.

 

Despite this prolonged operating underperformance, the Board does not appear to have taken sufficient action to improve operations or hold management accountable.

14

We Believe the Board Has Demonstrated an Inability to Properly Oversee the Company

GCP has shown an extraordinary inability to forecast results having now missed either Wall Street consensus revenue or EPS, or both, for fifteen of sixteen quarters since going public in 2016, including the most recent reported results. This was punctuated by a significant reduction in financial guidance causing the stock to decline to multi-year lows. While we appreciate that these businesses are subject to certain end market factors that impact results quarter to quarter, GCP has historically been unable to forecast results with any reasonable accuracy. Again, this is against a backdrop of favorable end market dynamics over the past several years.

 

15

These persistent misses, in our view, reflect a poorly executed business plan by management, poor communication of expectations to investors and ultimately, a lack of appropriate Board oversight in allowing this underperformance to continue.

We are Concerned with the Board’s Ability to Properly Oversee and Manage Cost Initiatives

We struggle to understand how GCP claims to have taken significant costs out of the business yet adjusted EBIT continues to decline despite revenue continuing to increase through 2018. Despite a similar revenue base, adjusted EBIT in 2019 was almost 30% less than it was in 2016.

16

We Believe the Board Has a History of Troubling Executive Compensation Practices

The Company’s poor pay practices started with the separation from W. R. Grace. At that time, the outstanding W. R. Grace stock options and restricted stock units held by named executive officers were converted to Company stock options and restricted stock units; and the named executive officers also received a regular grant of Company stock options, restricted stock units, and performance-based units. These officers also participated in the distribution of Company stock in respect to their W. R. Grace shares, the same as other W. R. Grace stockholders. That all seems expected and quite sufficient.

However, in addition to the regular grant and the conversion of the W.R. Grace stock options, the Company also granted the named executive officers a “Leadership” award equal in value to the regular, annual award (i.e., as if to “double down”). The purpose for this award was to strengthen the officers’ alignment with stockholders and to continue to motivate and retain the officers during the public launch. Given all the shares received at separation, on conversion of the W.R. Grace compensation equity, and in the Company’s regular annual grant, we believe this Leadership grant was excessive. And not only was the award unneeded and excessive, it was primarily a time-based restricted stock award (i.e., 67% of the value) that had executive-friendly vesting provisions for certain of the officers. The heavy use of time-based restricted stock for the CEO was particularly problematic, given the CEO had a combined retirement plan and SERP benefit of over $8 million. The Leadership award was piling on, which the Company hoped to obscure with the claimed need to align with stockholders following the separation transaction with W.R. Grace.

The Company’s declining financial and stock price performance, particularly in 2018 and 2019, is the background for other painful executive compensation errors. In 2018, the Company increased the value of equity awards to the named executive officers by a weighted average of 16%. Also, in 2018, the Company paid an annual incentive plan amount based on the achievement of only an annual revenue goal, even though the company failed to pay any incentive plan amount in respect to either its adjusted EBIT or adjusted free cash flow goals. The payment of an incentive based solely on account of revenue when profitability and free cash flow were below expectations is the wrong priority for the Company. Finally, the Board’s compensation committee retained an advisor that was paid more than $450,000 by management in 2018 for risk management and brokerage services.

More recently, the Board has made other questionable compensation decisions. Although we were pleased to see Gregory Poling step down as CEO of the Company, we were shocked to learn that he would be taking on the newly created role of Executive Chairman. The need for him in that role seems unlikely as the new CEO had previously been the CEO of a public company, and the new CEO and Mr. Poling had overlapped at the Company for almost one year – there had been plenty of time to transition Mr. Poling’s work to an experienced CEO. Perhaps the reason for such a role was less about the actual needs of the Company, but rather about the benefits Mr. Poling reaped by continuing to serve as an officer of the Company, including continuing to receive executive compensation, equity awards and other benefits to which he was previously entitled, such as his participation in the Company’s Severance Plan for Leadership Team Officers and his existing Change in Control Severance Agreement. By appointing Mr. Poling to this newly created role, the Board effectively committed to paying for two chief executives.

17

We find it incomprehensible that the dismal operating and financial performance that occurred under Mr. Poling’s leadership – in addition to initiating and shepherding the Company through a failed sale process – would warrant a decision by the Board to appoint him as Executive Chairman. We believe such a decision demonstrates the Board’s inability to act with the best interests of stockholders as the primary objective. Instead, it appears that the Board appointed Mr. Poling as Executive Chairman in order to allow him to continue to receive excessive compensation from the Company, in addition to maintaining his change of control severance package were GCP to eventually be sold. Although Mr. Poling retired from the role of Executive Chairman after only five months and as a member of the Board, we believe his departure would not have occurred without severe backlash from stockholders.

We Continue to Have Concerns with the Company’s Corporate Governance Practices

Despite the recent declassification of the Board, we continue to have concerns with various aspects of the Company’s governance structure. Specifically, stockholders are prohibited from taking action by written consent, are barred from calling special meetings and cannot fill vacancies on the Board, which we believe severely limits the ability of stockholders to seek to effect change at GCP. Moreover, these stockholder-unfriendly governance provisions are set forth in the Company’s Certificate of Incorporation, thereby requiring Board approval in order to amend such provisions.

Interestingly, the Board has touted its commitment to best-in-class governance practices yet has apparently failed to recognize two of the most important stockholder rights – the ability to act by written consent and the ability to call a special meeting – both of which are widely considered best-in-class corporate governance practices.

The Current Board Has Been Largely Unreceptive to Stockholders’ Input

For more than a year we have tried to meaningfully engage with the Company and voice our concerns. Unfortunately, despite our prior and continued efforts to engage constructively with the Company, the Company has seemingly been resistant to our efforts and dismissive of our views. We believe this lack of engagement with us, one of the Company’s largest stockholders, is both troubling and demonstrates that the current leadership does not appropriately value stockholder feedback.

 

18

 We Believe That Additional Stockholder Representation on the Board Is Necessary

We believe the Board’s collective lack of a substantial vested interest in shares of GCP may compromise the Board’s ability to properly evaluate and address the opportunities to enhance stockholder value at the Company with the best interests of stockholders in mind. According to public filings, the entire Board collectively owns less than 1% of the Company’s outstanding shares of Common Stock. Accordingly, there is no significant stockholder representation on the Board.  We believe the stockholders, as the true owners of the Company, need to have a strong voice at the Board level.  Such a voice promotes greater accountability and creates an environment that forces other directors to consider new and innovative ways to positively impact stockholder value.

19

Conversely, our Nominees collectively beneficially own approximately 8.2% of the Company’s outstanding shares of Common Stock.  It seems apparent to us that with so little “skin in the game” and not enough confidence in the Company to engage in meaningful stock purchases, the Board does not have the same commitment to stockholder value as we do.  We believe a culture focused on long-term value creation and stockholder accountability requires placing stockholder representatives on the Board who have a significant financial commitment to the Company along with relevant experience.  This requirement ensures the proper alignment of interests between the Board and stockholders.

We Believe There is a Better Path Forward for GCP

While GCP has experienced significant challenges, we believe its poor financial and stock price performance has created a unique opportunity to invest in a market leader and embark on a multi-year operational turnaround that can deliver outstanding returns to stockholders. We do not believe that the Company’s management team or Board have followed through on their past commitments to grow revenue and cut costs, and we believe it is time for substantial change in order to chart a new course for GCP.

Despite its recent problems, GCP is fundamentally a great company with promising future prospects. We believe the SCC business should be a market leader and with the appropriate focus and execution, we believe SCC can drive meaningful profitability improvements while continuing to drive improved revenue trends. Similarly, in the Company’s SBM segment, GCP is also a market leader and frequently designed into some of the largest and most visible construction projects globally. Our diligence has indicated that there is significant untapped potential in this business through further product line expansion and development.

We believe that GCP needs a new plan, with improved execution and greatly enhanced board oversight. Starboard has significant experience in these areas with a long, successful track record of driving operational, financial, strategic, and governance changes that benefit employees, customers, and stockholders. We firmly believe that with the right Board in place, GCP can be a best-in-class company in its industry and generate significant value for all stockholders.

We are confident that you will find the slate of professionals we are nominating to be incredibly well-qualified to serve as directors of GCP. As you can see from our Nominees’ detailed biographies in the following pages, this group of extremely impressive director candidates has backgrounds spanning operations, finance, private equity, mergers and acquisitions, restructuring, strategic transformation, and public company governance as well as substantial experience in the chemical, construction, and broader industrial industries. Collectively, they have decades of experience as CEOs, senior executives, chairmen and directors of well-performing industrial companies.

In contrast to our Nominees who possess decades of experience across the chemical, construction, and broader industrial industries, the current Board appears to have limited executive experience in these same industries. Furthermore, there are a number of instances of current GCP Board members serving on outside boards together, potentially indicating a lack of independence amongst certain of the current Board members.

If elected, our Nominees, subject to their fiduciary duties, are committed to implementing a comprehensive turnaround plan aimed at unlocking the full potential of GCP. We look forward to publicly releasing a comprehensive turnaround plan over the coming weeks and months. While we have confidence that our director nominees’ plans for GCP will put the Company on the right path towards substantial stockholder value creation, there can be no assurance that the implementation of this comprehensive turnaround plan will ultimately enhance stockholder value. In the event that our director nominees comprise less than a majority of the Board following the Annual Meeting, there can be no assurance that any actions or changes proposed by our director nominees, including the implementation of any turnaround plan, will be adopted or supported by the Board.

Starboard V&O Fund, Starboard S LLC, Starboard C LP, Starboard L Master, Starboard L GP, Starboard R LP, Starboard R GP, Starboard Value LP, Starboard Value GP, Principal Co, Principal GP, Mr. Smith, and the Nominees (collectively, the “Group”) entered into a Joint Filing and Solicitation Agreement in which, among other things, (i) the Group agreed to solicit proxies or written consents for the election of the Nominees, or any other person(s) nominated by Starboard V&O Fund, to the Board at the Annual Meeting, (ii) the Group agreed to take all other action the Group deems necessary or advisable to achieve the foregoing, and (iii) Starboard V&O Fund, Starboard S LLC, Starboard C LP, Starboard L Master, and Starboard Value LP through the Starboard Value LP Account agreed to bear all expenses incurred in connection with the Group’s activities, including approved expenses incurred by any of the parties in connection with the solicitation, subject to certain limitations.

Each of the Nominees, as a member of a “group” for the purposes of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), may be deemed to beneficially own the shares of Common Stock owned in the aggregate by the other members of the Group. Each of the Nominees specifically disclaims beneficially ownership of the shares of Common Stock owned by the other members of the Group. For information regarding purchases and sales of securities of the Company during the past two years by the participants in this solicitation, see Schedule I.

27

Starboard V&O Fund has signed separate letter agreements with each of the Nominees (other than Messrs. Feld, Molinelli and Kiefaber and Ms. Ogilvie) pursuant to which it and its affiliates have agreed to indemnify such Nominees against certain claims arising from the solicitation of proxies from the Company’s stockholders in connection with the Annual Meeting and any related transactions. For the avoidance of doubt, such indemnification does not apply to any claims made against such Nominees in their capacities as directors of the Company, if so elected.

Starboard V&O Fund has signed compensation letter agreements (the “Compensation Letter Agreements”) with each of the Nominees (other than Messrs. Feld, Molinelli and Kiefaber and Ms. Ogilvie), pursuant to which it has agreed to pay each of such Nominees: (i) $25,000 in cash as a result of the submission by Starboard V&O Fund of its nomination of each of such Nominees to the Company and (ii) $25,000 in cash upon the filing by Starboard V&O Fund of a definitive proxy statement with the SEC relating to the solicitation of proxies in favor of such Nominees’ election as directors of the Company. Pursuant to the Compensation Letter Agreements, each of such Nominees has agreed to use the after-tax proceeds from such compensation to acquire securities of the Company (the “Nominee Shares”) at such time that each of such Nominees shall determine, but in any event no later than fourteen (14) days after receipt of such compensation, subject to Starboard V&O Fund’s right to waive the requirement to purchase the Nominee Shares. Pursuant to the Compensation Letter Agreements, each of such Nominees has agreed not to sell, transfer or otherwise dispose of any Nominee Shares until the earliest to occur of (i) the Company’s appointment or nomination of such Nominee as a director of the Company, (ii) the date of any agreement with the Company in furtherance of such Nominee’s nomination or appointment as a director of the Company, (iii) Starboard V&O Fund’s withdrawal of its nomination of such Nominee for election as a director of the Company, and (iv) the date of the Annual Meeting; provided, however, in the event that the Company enters into a business combination with a third party, each of such Nominees, may sell, transfer or exchange the Nominee Shares in accordance with the terms of such business combination.

Starboard believes that each Nominee presently is, and if elected as a director of the Company, each of the Nominees would be, an “independent director” within the meaning of (i) applicable New York Stock Exchange (“NYSE”) listing standards applicable to board composition and (ii) Section 301 of the Sarbanes-Oxley Act of 2002. No Nominee is a member of the Company’s compensation, nominating or audit committee that is not independent under any such committee’s applicable independence standards.

According to the Company’s 2019 definitive proxy statement, the Company has determined that Mr. Kiefaber and Ms. Ogilvie qualify as independent directors under applicable rules and regulations and GCP’s independence standards. Each of Mr. Kiefaber and Ms. Ogilvie currently serve on the Compensation, Nominating & Governance and Corporate Responsibility Committees of the Board. Mr. Kiefaber also serves on the Company’s Audit Committee.

Other than as stated herein, and except for compensation received by each of Messrs. Feld and Molinelli as an employee of Starboard Value LP, there are no arrangements or understandings between Starboard and any of the Nominees or any other person or persons pursuant to which the nomination of the Nominees described herein is to be made, other than the consent by each of the Nominees to be named in this Proxy Statement and to serve as a director of the Company if elected as such at the Annual Meeting.  None of the Nominees is a party adverse to the Company or any of its subsidiaries or has a material interest adverse to the Company or any of its subsidiaries in any material pending legal proceedings.

28

If Starboard is successful in obtaining stockholder approval for the election of five (5) or more of the Nominees at the Annual Meeting, then a change of control of the Board may be deemed to have occurred under certain of the Company’s material contracts.  Based on a review of the Company’s material contracts and agreements, such a change of control may trigger certain change of control provisions or payments contained therein as described below.

Pursuant to the Company’s 2016 Stock Incentive Plan (the “2016 Plan”), a change in control occurs, among other things, if individuals who are “Continuing Directors”, which term means any member of the Board who was such a member on the date on which the 2016 Plan was approved by the Compensation Committee and any successor to such a director who is approved as a nominee or elected to succeed such director by a majority of Continuing Directors who are then members of the Board, cease to constitute a majority of any class of the Board. In the event that Starboard is successful in electing five (5) or more of the Nominees at the Annual Meeting, a change of control under the 2016 Plan could be triggered. Under the 2016 Plan, a change in control would (A) accelerate the vesting of any options and stock appreciation rights outstanding, (B) provide for the lapse of all restrictions and deferral limitations of any restricted stock award and (C) during the sixty day period from and after the change of control, unless the Compensation Committee determines otherwise at the time of grant, the holder of an option shall have the right to receive cash in lieu of the payment of the purchase price for the shares of Common Stock under the option, in accordance with the procedures set forth in the 2016 Plan.

Pursuant to the Company’s Change in Control Severance Agreement (the “Severance Agreements”), entered into between the Company and its executive officers, a change in control occurs, among other things, if individuals who are “Continuing Directors”, which term means any member of the Board who was such a member on the date a Severance Agreement was entered into and any successor to such a Continuing Director who is approved as a nominee or elected to succeed such director by a majority of Continuing Directors who are then members of the Board, cease to constitute a majority of any class of the Board. In the event that Starboard is successful in electing five (5) or more of the Nominees at the Annual Meeting, a change in control under the Severance Agreements could be triggered, however, the change in control provisions under the Severance Agreements are double-trigger provisions, meaning that a change in control in and of itself does not trigger any payments or benefits under the Severance Agreements, but rather there would also need to be a qualifying termination of the affected executives or resignation for “good reason” before any additional or accelerated obligations are triggered. Specifically, under the Severance Agreements, executive officers are entitled to change in control payments and severance benefits in the event that there is a change in control of the Company and, within 24 months after the change in control, either the executive resigns for good reason or the executive experiences an involuntary termination of employment for reasons other than cause.

Pursuant to the Company’s Executive Annual Incentive Compensation Plan (the “Compensation Plan”), a change in control occurs, among other things, if individuals who are “Continuing Directors”, which term means any member of the Board who was such a member on the date a Compensation Plan was entered into and any successor to such a Continuing Director who is approved as a nominee or elected to succeed such director by a majority of Continuing Directors who are then members of the Board, cease to constitute a majority of any class of the Board. In the event that Starboard is successful in electing five (5) or more of the Nominees at the Annual Meeting, a change of control under the Compensation Plan could be triggered.  Under the Compensation Plan, a change in control would permit the Compensation Committee to take all such actions as it may determine to be necessary or appropriate including, without limitation, the modification or waiver of applicable Performance Goals, Performance Criteria, Performance Periods, or Awards, notwithstanding the terms of any initial award (as such terms are defined under the Compensation Plan).

29

Pursuant to the Company’s 2015 Restricted Stock Unit Agreement (the “RSU Agreement”), a change in control occurs, among other things, if individuals who are “Continuing Directors”, which term means any member of the Board who was such a member on the date on which the RSU Agreement was approved by the Board and any successor to such a Continuing Director who is approved as a nominee or elected to succeed such director by a majority of Continuing Directors who are then members of the Board, cease to constitute a majority of any class of the Board. In the event that Starboard is successful in electing five (5) or more of the Nominees at the Annual Meeting, a change in control under the RSU Agreement could be triggered. Under the RSU Agreement, a change in control would permit the Compensation Committee, with respect to restricted share units, to (A) accelerate the vesting of any restricted share units, (B) accelerate the payment related to any restricted share units, and (C) take other action deemed by it to be appropriate and in the best interests of the Company under the circumstances.

Pursuant to the Company’s Equity and Incentive Plan, as amended and restated on February 28, 2017 (the “Equity & Incentive Plan”), a change in control occurs, among other things, if a change occurs in the composition of the Board such that persons who, as of February 28, 2017 constitute the Board (“Incumbent Directors”) cease for any reason (including with limitation, as a result of a tender offer, proxy contest, merger or similar transaction) to constitute at least a majority thereof, provided, however, that any person who becomes a director of the Company subsequent to February 28, 2017 shall be considered an Incumbent Director if such person’s election or nomination for election was approved by a vote of at least fifty percent (50%) of the Incumbent Directors; provided, further, that any such person whose initial assumption of office is in connection with an actual or threatened proxy contest relating to the election of members of the Board or other actual or threatened solicitation of proxies or consents by or on behalf of a person other than the Board, including by reason of agreement intended to avoid or settle any such actual or threatened contest or solicitation, shall not be considered an Incumbent Director. In the event that Starboard is successful in electing five (5) or more of the Nominees at the Annual Meeting, a change in control under the Equity & Incentive Plan could be triggered. Under the Equity & Incentive Plan, a change in control would provide for certain actions to apply, including, but not limited to (A) the payment of the participant’s annual performance bonus in full at such time and in such manner as determined by the Compensation Committee, in its sole discretion, (B) the immediate vesting in full of a participant’s stock options, stock appreciation rights and other stock-based awards and (C) the immediate vesting in a pro-rata portion of the participant’s long-term performance awards based on the procedures set forth in the Equity & Incentive Plan.

Starboard has not independently verified if the copies of the agreements publicly filed by the Company with the SEC and discussed above (collectively, the “Company Agreements”) are the same as the actual executed copies of the agreements, and the analyses above are based on our review of the Company’s public SEC filings. While we are not aware of any, there may be other agreements that may be triggered by a change in control in connection with the nomination and/or election of the Nominees. The discussion of the potential impact of the nomination is based entirely upon our review of the Company Agreements.  Notwithstanding the foregoing, Starboard would expect the Board, consistent with its fiduciary duties, to take any and all action necessary to render inapplicable any change in control provision that would be triggered by the nomination and/or election of the Nominees under the Company Agreements, as necessary and to the extent applicable and permitted.

30

We do not expect that any of the Nominees will be unable to stand for election, but, in the event any Nominee is unable to serve or for good cause will not serve, the shares of Common Stock represented by the enclosed WHITE proxy card will be voted for substitute nominee(s), to the extent this is not prohibited under the Company’s Amended and Restated By-laws (the “Bylaws”) and applicable law. In addition, we reserve the right to nominate substitute person(s) if the Company makes or announces any changes to the Bylaws or takes or announces any other action that has, or if consummated would have, the effect of disqualifying any Nominee, to the extent this is not prohibited under the Bylaws and applicable law. In any such case, shares of Common Stock represented by the enclosed WHITE proxy card will be voted for such substitute nominee(s). We reserve the right to nominate additional person(s), to the extent this is not prohibited under the Bylaws and applicable law, if the Company increases the size of the Board above its existing size or increases the number of directors whose terms expire at the Annual Meeting. Additional nominations made pursuant to the preceding sentence are without prejudice to the position of Starboard that any attempt to increase the size of the current Board or to re-classify the Board constitutes an unlawful manipulation of the Company’s corporate machinery.

WE URGE YOU TO VOTE FOR THE ELECTION OF THE NOMINEES ON THE ENCLOSED WHITE PROXY CARD.

31

PROPOSAL NO. 2

RATIFICATION OF APPOINTMENT OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

As discussed in further detail in the Company’s proxy statement, the Board has appointed PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for 2020. The Company is submitting the appointment of PricewaterhouseCoopers LLP for ratification of the stockholders at the Annual Meeting. According to the Company’s proxy statement, if the selection is not ratified, the Audit Committee will reconsider its selection of PricewaterhouseCoopers LLP for future years.

[WE MAKE NO RECOMMENDATION WITH RESPECT TO THIS PROPOSAL AND INTEND TO VOTE OUR SHARES [“FOR”] THIS PROPOSAL.]

32

PROPOSAL NO. 3

ADVISORY VOTE TO APPROVE THE

COMPENSATION OF GCP’S NAMED EXECUTIVE OFFICERS

As disclosed in the Company’s proxy statement, under Section 14A of the Exchange Act, the Company’s stockholders are entitled to vote on a proposal to approve on an advisory (non-binding) basis, the compensation of the named executive officers. This proposal, commonly known as a “say-on-pay” proposal, is not intended to address any specific item of compensation, but rather the overall compensation of the Company’s named executive officers and the philosophy, policies and practices described in the Company’s proxy statement. Accordingly, the Company is asking stockholders to vote for the following resolution:

[“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby approved.”]

[WE MAKE NO RECOMMENDATION WITH RESPECT TO THIS PROPOSAL] AND INTEND TO VOTE OUR SHARES [“FOR”/”AGAINST”] THIS PROPOSAL.

33

VOTING AND PROXY PROCEDURES

Stockholders are entitled to one vote for each share of Common Stock held of record on the Record Date with respect to each matter to be acted on at the Annual Meeting. Only stockholders of record on the Record Date will be entitled to notice of and to vote at the Annual Meeting. Stockholders who sell their shares of Common Stock before the Record Date (or acquire them without voting rights after the Record Date) may not vote such shares of Common Stock. Stockholders of record on the Record Date will retain their voting rights in connection with the Annual Meeting even if they sell such shares of Common Stock after the Record Date. Based on publicly available information, Starboard believes that the only outstanding class of securities of the Company entitled to vote at the Annual Meeting is the Common Stock.

Shares of Common Stock represented by properly executed WHITE proxy cards will be voted at the Annual Meeting as marked and, in the absence of specific instructions, will be voted FOR the election of the Nominees, [FOR] the ratification of the appointment of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm, and [FOR/AGAINST] an advisory (non-binding) proposal concerning the Company’s executive compensation program and in the discretion of the persons named as proxies on all other matters as may properly come before the Annual Meeting, as described herein.

The Board is currently composed of nine (9) directors, each with terms expiring at the Annual Meeting. According to the Company’s proxy statement for the Annual Meeting, the current Board intends to nominate [nine (9)] candidates for election at the Annual Meeting. This Proxy Statement is soliciting proxies to elect only our Nominees. Accordingly, the enclosed WHITE proxy card may only be voted for our Nominees and does not confer voting power with respect to the Company’s nominees. The participants in this solicitation intend to vote the Starboard Group Shares in favor of the Nominees. Stockholders should refer to the Company’s proxy statement for the names, backgrounds, qualifications and other information concerning the Company’s nominees.   In the event that some of the Nominees are elected, there can be no assurance that the Company nominee(s) who get the most votes and are elected to the Board will choose to serve as on the Board with the Nominees who are elected.

While we currently intend to vote all of the Starboard Group Shares in favor of the election of the Nominees, we reserve the right to vote some or all of the Starboard Group Shares for some or all of the Company’s director nominees, as we see fit, in order to achieve a Board composition that we believe is in the best interest of all stockholders. We would only intend to vote some or all of the Starboard Group Shares for some or all of the Company’s director nominees in the event it were to become apparent to us, based on the projected voting results at such time, that by voting the Starboard Group Shares we could help elect the Company nominee(s) that we believe are the most qualified to serve as directors and thus help achieve a Board composition that we believe is in the best interest of all stockholders. Stockholders should understand, however, that all shares of Common Stock represented by the enclosed WHITE proxy card will be voted at the Annual Meeting as marked.

34

QUORUM; BROKER NON-VOTES; DISCRETIONARY VOTING

A quorum is the minimum number of shares of Common Stock that must be represented at a duly called meeting in person or by proxy in order to legally conduct business at the meeting. For the Annual Meeting, the presence, in person or by proxy, of the holders of at least a majority of the outstanding shares of Common Stock as of the Record Date will be considered a quorum for the transaction of business.

Abstentions are counted as present and entitled to vote for purposes of determining a quorum. Shares represented by “broker non-votes” also are counted as present and entitled to vote for purposes of determining a quorum. However, if you hold your shares in street name and do not provide voting instructions to your broker, your shares will not be voted on any proposal on which your broker does not have discretionary authority to vote (a “broker non-vote”). Under applicable rules, your broker will not have discretionary authority to vote your shares at the Annual Meeting on any of the proposals.

If you are a stockholder of record, you must deliver your vote by mail, attend the Annual Meeting in person and vote, vote by Internet or vote by telephone in order to be counted in the determination of a quorum.

If you are a beneficial owner, your broker will vote your shares pursuant to your instructions, and those shares will count in the determination of a quorum. Brokers do not have discretionary authority to vote on any of the proposals at the Annual Meeting. Accordingly, unless you vote via proxy card or provide instructions to your broker, your shares of Common Stock will count for purposes of attaining a quorum, but will not be voted on the proposals.

VOTES REQUIRED FOR APPROVAL

Election of Directors ─ The Company has adopted a majority vote standard for non-contested director elections and a plurality vote standard for contested director elections. As a result of our nomination of the Nominees, the director election at the Annual Meeting will be contested, so the nine (9) nominees for director receiving the highest vote totals will be elected as directors of the Company. With respect to the election of directors, only votes cast “FOR” a nominee will be counted. Proxy cards specifying that votes should be withheld with respect to one or more nominees will result in those nominees receiving fewer votes but will not count as a vote against the nominees. Neither an abstention nor a broker non-vote will count as a vote cast “FOR” or “AGAINST” a director nominee. Therefore, abstentions and broker non-votes will have no direct effect on the outcome of the election of directors.

Ratification of the Appointment of Accounting Firm ─ According to the Company’s proxy statement, assuming that a quorum is present, the affirmative vote of a majority of the shares present, in person or by proxy, and entitled to vote is required to approve the ratification of the appointment of PricewaterhouseCoopers LLP as GCP’s independent registered public accounting firm for fiscal year 2020. The Company has indicated that abstentions will have the same effect as votes against the proposal.

35

Advisory Vote on Executive Compensation ─ According to the Company’s proxy statement, although the vote is non-binding, assuming that a quorum is present, the affirmative vote of a majority of the shares present, in person or by proxy, and entitled to vote will constitute the approval, on an advisory, non-binding basis, of the compensation of GCP’s named executive officers. The Company has indicated that abstentions will have the same effect as votes against the proposal. Broker non-votes will have no effect on the outcome of the vote.

Under applicable Delaware law, none of the holders of Common Stock is entitled to appraisal rights in connection with any matter to be acted on at the Annual Meeting. If you sign and submit your WHITE proxy card without specifying how you would like your shares voted, your shares will be voted in accordance with Starboard’s recommendations specified herein and in accordance with the discretion of the persons named on the WHITE proxy card with respect to any other matters that may be voted upon at the Annual Meeting.

REVOCATION OF PROXIES

Stockholders of the Company may revoke their proxies at any time prior to exercise by attending the Annual Meeting and voting in person (although attendance at the Annual Meeting will not in and of itself constitute revocation of a proxy) or by delivering a written notice of revocation. The delivery of a subsequently dated proxy which is properly completed will constitute a revocation of any earlier proxy. The revocation may be delivered either to Starboard in care of Okapi Partners at the address set forth on the back cover of this Proxy Statement or to the Company at 62 Whittemore Avenue, Cambridge, Massachusetts 02140 or any other address provided by the Company. Although a revocation is effective if delivered to the Company, we request that either the original or photostatic copies of all revocations be mailed to Starboard in care of Okapi Partners at the address set forth on the back cover of this Proxy Statement so that we will be aware of all revocations and can more accurately determine if and when proxies have been received from the holders of record on the Record Date of a majority of the outstanding shares of Common Stock. Additionally, Okapi Partners may use this information to contact stockholders who have revoked their proxies in order to solicit later dated proxies for the election of the Nominees.

IF YOU WISH TO VOTE FOR THE ELECTION OF THE NOMINEES TO THE BOARD, PLEASE SIGN, DATE AND RETURN PROMPTLY THE ENCLOSED WHITE PROXY CARD IN THE POSTAGE-PAID ENVELOPE PROVIDED.
