Executive Summary

• KVH is executing on a strategy to drive growth and long-term shareholder value by focusing on three priorities: 1) Accelerating our AgilePlans subscription offering, 2) Commercializing our Photonic Integrated Chip (PIC) technology, and 3) Investing in our KVH Watch Internet of Things (IoT) platform • These initiatives are in different states of maturation and revenue generation – but they are all unique solutions focused on large growing markets where we are confident we can gain significant traction • After years of focused investment, we believe our shift towards more cost-effective and recurring revenue new products, and our migration to our next-generation satellite network, will significantly boost profitability and position KVH to generate higher returns for shareholders Executive Summary (1 of 2) • Our diversified and sustainable business model has proven to be a competitive advantage – helping KVH navigate through COVID-19 better than competitors while maintaining a strong balance sheet • KVH has invested heavily in the AgilePlans CaaS (Connectivity as a Service) and the Mobile Connectivity segment, and our financial results are improving overall • Our new PIC technology should enable our Inertial Navigation business to penetrate the growing autonomous market in the mid- term A focused long-term strategy A business model optimized for growth Recent results show that KVH is delivering on its plan • KVH has significant momentum and has outperformed its peers YTD and over one and five years • Strong first quarter results ahead of expectations – including 16% revenue growth and a 48% increase in AgilePlans revenue – demonstrate that the strategy is working • KVH expects to generate profitable growth over the mid-term, including low double- digit revenue CAGRs and EBITDA margins in the mid-teens1 4 1 See slide 78 for more information regarding KVH’s Adjusted EBITDA margin.

Executive Summary (2 of 2) • With the election of KVH’s two new nominees, four of our six independent directors will have been added since the beginning of 2020 – including one as part of our engagement with ~9% shareholder Vintage Capital • Following the addition of Ms. Hernandez and Ms. Martine, half of the independent directors will be female, most will have navigation or telecommunications experience and the average tenure will be less than five years • The Board has a track record of engaging constructively with shareholders and tried to do the same here – but after one conversation with the Company, VIEX delivered a notice of intent to nominate and then VIEX rejected numerous reasonable attempts to settle • KVH’s nominees – Cielo Hernandez and Cathy- Ann Martine-Dolecki – were identified by a leading independent director search firm, have no prior connections to the Board or the Company and will bring fresh perspectives to the KVH boardroom • Ms. Hernandez and Ms. Martine specifically possess the deep global telecommunications, commercial maritime, financial and executive leadership experience that will be directly valuable to the Company The right board and governance practices KVH’s candidates bring relevant expertise and enhance board diversity VIEX’s nominees are not the right candidates for the Board • VIEX and its group are recent investors that have demonstrated virtually no knowledge of our business and have no plan for improvement • VIEX’s nominees have troubling records and no relevant industry experience • KVH’s Board believes the fact that three members of the VIEX group, Eric Singer, Peter Shaper and Potomac Capital, have been found by courts of law to have breached or aided and abetted the breach of fiduciary duties as directors is highly concerning and further demonstrates that they are not the right choice 5

Cielo Hernandez • CFO of XL Fleet Corp, a leading provider of fleet electrification solutions for commercial vehicles in North America • Previously served as Vice President and CFO for the North America region at A.P. Moeller-Maersk A/S, the largest container shipping line and vessel operator in the world • Held leadership roles at APM Terminals, Amcor and DIRECTV • Her experience in the maritime sector and at DIRECTV will be invaluable to KVH as the leader in marine satellite television for more than 25 years Our 2021 Nominees Bring Relevant and Complementary Expertise Cathy-Ann Martine-Dolecki Former Executive at AT&T (NYSE: T) • Ms. Martine brings extensive global leadership in the telecommunications industry • Led a $25B business for AT&T where she served as President, Enterprise Business Solutions of AT&T Mobile & Business Solutions • Her professional background will be especially valuable in helping guide KVH as it moves towards a blended 5G hybrid satellite solution Chief Financial Officer of XL Fleet Corp.

13 VIEX’s Nominees Are the Wrong Choice x Mr. Mutch has deep connections to Mr. Singer, having served on boards with or been nominated as a director candidate by Mr. Singer at least seven times4, including at a recent campaign in an entirely different industry (Leaf Group) x Mr. Mutch appears to have no experience in areas directly relevant to KVH’s business, such as maritime and satellite communications x Mr. Mutch’s election would undo some of the progress our Board has made around enhancing diversity x Mr. Mutch’s track record as a director is underwhelming, with his median TSR falling well short of the S&P 500 and Russell 3000 indices2 x Mr. Singer has a highly concerning history of legal issues; Mr. Singer has the rare distinction of having been found by a Delaware court to have breached his fiduciary duty of loyalty to public company shareholders by purposefully withholding material information from his fellow directors about the intentions of a bidder in order to further his “divergent” interests1 x His track record as a director is abysmal. He has served on the boards of 12 public companies in the last ten years, and every one of those 12 companies has underperformed the S&P 500 and the Russell 3000 during his tenure2 x Mr. Singer has admitted that he does not have any specific plan for how KVH could improve its performance x His seeming disregard for board diversity, as evidenced by his nomination of only one woman out of nearly 40 director candidates, is extremely troubling3 Eric Singer John Mutch Managing Director, MV Advisors, LLC Founder and Portfolio Manager, VIEX Capital Advisors, LLC Former Co-Managing Member of Potomac Capital Management 4 VIEX nominated Mr. Mutch to the boards of KVH Industries (Nasdaq: KVHI) in March 2021 (source), Leaf Group (NYSE: LEAF) in February 2021 (source), Maxwell Technologies (formerly Nasdaq: MXWL) in April 2017 (source), and Quantum Corporation in June 2016 (source) and 2017 (source).

32 Analyst Support For KVH’s Direction We reiterate Outperform rating on KVHI and raise target price to $16, from $15, after 1Q21 results helped by the completion of a large TACNAV order announced in 2Q20, and with a possible end in sight for the maritime industry's COVID-19 headwinds.”1 KVHI is driving growth and margin expansion through new product introduction and subscriber migration to High-Throughput Satellites (HTS, with airtime revenue up 56% y/y), and legacy network usage expected to be turned off 12/31/2021.”1 Our long-term thesis remains intact: the shift towards recurring connectivity-as-a-service revenue via AgilePlans and KVH Watch, should create more predictable free cash flows, with AgilePlan revenues up 48% y/y and 41% of subs now on the plans (vs. 38% in 4Q20).”1 KVH started 2021 on a strong note, reporting better than expected financial results and encouraging trends in the mini-VSAT business, including: (1) double-digit airtime growth, (2) record VSAT shipments for the second straight quarter, (3) record customer demand for AgilePlans, and (4) a healthy margin improvement.”2 May 17, 2021 May 5, 2021 1 Raymond James, Reiterate Outperform, Raise PT to $16; Improving Margins and Macros Drive LT Cash Generation (May 5, 2021).

44 KVH Protected Jobs During the Pandemic 1 New York Times, Pay Cuts Become a Tool for Some Companies to Avoid Layoffs (May 24, 2020). Permission to use quotation neither sought nor obtained. Emphasis added to quotation. Martin. A. Kits van Heyningen, chief executive of KVH Industries, decided to cut salaries rather than lay off workers. “It was one of the hardest things I’ve done,” he said. “It was late and Martin A. Kits van Heyningen feared he was letting the team down at the company he co-founded, KVH Industries. Rather than lay off workers in response to the coronavirus pandemic, he had decided to cut salaries, and when he emailed a video explaining his decision at 3 a.m. last month, he was prepared for a barrage of complaints. Instead, he woke to an outpouring of support from employees that left him elated. “It was one of the hardest things I’ve done, but it turned out to be the best day of my life at work,” said Mr. Kits van Heyningen. “I was trying to keep their morale up. Instead, they kept my morale up.” Even as American employers let tens of millions of workers go, some companies are choosing a different path. By instituting across-the-board salary reductions, especially at senior levels, they have avoided layoffs.”1

VIEX’s Nominees Are Wrong For the KVH Board

46 VIEX’s Nominees Are the Wrong Choice x Mr. Mutch has deep connections to Mr. Singer, having served on boards with or been nominated as a director candidate by Mr. Singer at least seven times4, including at a recent campaign in an entirely different industry (Leaf Group) x Mr. Mutch appears to have no experience in areas directly relevant to KVH’s business, such as maritime and satellite communications x Mr. Mutch’s election would undo some of the progress our Board has made around enhancing diversity x Mr. Mutch’s track record as a director is underwhelming, with his median TSR falling well short of the S&P 500 and Russell 3000 indices2 x Mr. Singer has a highly concerning history of legal issues; Mr. Singer has the rare distinction of having been found by a Delaware court to have breached his fiduciary duty of loyalty to public company shareholders by purposefully withholding material information from his fellow directors about the intentions of a bidder in order to further his “divergent” interests1 x His track record as a director is abysmal. He has served on the boards of 12 public companies in the last ten years, and every one of those 12 companies has underperformed the S&P 500 and the Russell 3000 during his tenure2 x Mr. Singer has admitted that he does not have any specific plan for how KVH could improve its performance x His seeming disregard for board diversity, as evidenced by his nomination of only one woman out of nearly 40 director candidates, is extremely troubling3 Eric Singer John Mutch Managing Director, MV Advisors, LLC Founder and Portfolio Manager, VIEX Capital Advisors, LLC Former Co-Managing Member of Potomac Capital Management 4 VIEX nominated Mr. Mutch to the boards of KVH Industries (Nasdaq: KVHI) in March 2021 (source), Leaf Group (NYSE: LEAF) in February 2021 (source), Maxwell Technologies (formerly Nasdaq: MXWL) in April 2017 (source), and Quantum Corporation in June 2016 (source) and 2017 (source).

49 Eric Singer, Potomac Capital and PLX Technology: A Telling Judgment In 2013, Potomac Capital Partners, co-managed by Eric Singer, nominated 5 directors to the PLX Technology Board of Directors 1 Potomac Capital’s Letter to the PLX Technology Board of Directors (January 15, 2013). Permission to use quotation neither sought nor obtained. Emphasis added to quotation. 2 PLX Technology’s Investor Presentation (November 25, 2013). Permission to use quotation neither sought nor obtained. Emphasis added to quotation. Potomac’s first letter to the PLX Board, signed by Eric Singer, made it clear that Potomac was interested in a quick sale, stating that it was “imperative and urgent”1 that the board hire an investment bank and begin a strategic review process Throughout the campaign, PLX warned its shareholders that Mr. Singer and Potomac were not acting in the best interests of all shareholders, calling their campaign “self interested”2, “short term”2, “harmful”2, “disruptive”2, and “only focused on one thing”2 – selling PLX Despite PLX’s warnings, three of Potomac’s nominees, including Mr. Singer, were elected to the PLX Board

Eric Singer, Potomac Capital and PLX Technology: A Telling Judgment, Continued • As PLX had predicted, once seated on the Board, Mr. Singer was appointed Chair of a Special Committee formed to explore strategic alternatives and aggressively campaigned for the company to sell itself to Avago (now Broadcom) for $300 million • According to the Financial Times coverage of an October 2018 ruling from the Delaware Court of Chancery, the “sale had been effectively rigged”2 due to Mr. Singer’s misconduct: • Mr. Singer did not share with the rest of the PLX board his personal communications with the company’s financial advisor regarding Avago’s interest in acquiring PLX and his knowledge of the price Avago was willing to pay • Since Avago’s bid fell well below the valuation implied by PLX’s existing business plan, the Special Committee had management prepare a lower set of financial projections, which happened to place the bid in the middle of the range 1 In re PLX Tech. Inc., CONSOLIDATED C.A. No. 9880-VCL (Del. Ch. Oct. 16, 2018). 2 Financial Times, Court ruling gives Campbell Soup activist food for thought (November 18, 2018). Permission to use quotation neither sought nor obtained. Emphasis added to quotation. “… An activist fund, Potomac Capital Partners [led by Eric Singer], was found liable for helping engineer the PLX board’s quick-fire sale to its competitor Avago — now known as Broadcom — in breach of the PLX board’s duty to act in the best interests of all PLX shareholders.” 50 November 18, 2018 Once on PLX’s Board, A Court Found that Mr. Singer Engaged In Misconduct to Foster a Quick Sale1

51 Mr. Singer’s Conduct at PLX Falls Well Short of Our Standards Whipple: Singer “routinely threatened management and board members that he was going to sue them individually . . . if they didn't do what he wanted them to do”1 Schmitt: Singer “threatened . . . lawsuits all the time. That was his mode of operation at that point.”1 Riordan: “It’s not possible to have a constructive conversation with this guy because he doesn't care one whit about the company or its employees or its contribution.”1 Riordan: Q. But he threatened to sue you? A. Yeah, he did that all the time, right. That was his standard.”1 Whipple: Singer was “combative and a bully,” and took the position that “[e]verything that anybody does is horrible or wonderful; and as far as he’s concerned, nothing that PLX had managed to do was wonderful.”; “Q. What about being a bully? Was - was he a bully in the meeting? A: I've never seen him where he wasn’t.”1 Depositions from PLX Board members highlight Mr. Singer’s troubling conduct as a Board member: 1 In re PLX Tech. Inc., CONSOLIDATED C.A.

52 Mr. Singer Was Found to Have Breached His Duties The Delaware Chancery Court Concluded That Eric Singer Breached His Fiduciary Duty of Loyalty to the PLX Shareholders When He “Fatally Undermined the Sale Process”1 In my view, by withholding this information from the rest of the Board, Singer breached his fiduciary duty and induced the other directors to breach theirs. For present purposes, by withholding this information, he fatally undermined the sale process.”1 1 In re PLX Tech. Inc., CONSOLIDATED C.A. No. 9880-VCL, 23 n.112 (Del. Ch. Oct. 16, 2018). Potomac and Singer undermined the Board’s process and led the Board into a deal that it otherwise would not have approved…”1 No one can tell what would have happened if Singer … had been candid, but the Board might well have proceeded differently…”1 IN THE COURT OF CHANCERY OF THE STATE OF DELAWARE IN RE PLX TECHNOLOGY INC. ) CONSOLIDATED STOCKHOLDERS LITIGATION ) C.A.

The Chancellor’s opinion in the PLX case echoes many of the concerning themes from Singer’s conduct at KVH: 53 The Decision Also Echoes Many of Our Board’s Concerns Regarding Mr. Singer Potomac’s internal communications show that Singer had no meaningful ideas other than selling the Company. […] As its “plan,” Potomac incorporated nearly verbatim its proxy advisor’s generic list of ideas.”1 IN THE COURT OF CHANCERY OF THE STATE OF DELAWARE IN RE PLX TECHNOLOGY INC. ) CONSOLIDATED STOCKHOLDERS LITIGATION ) C.A.

Pre-Trial and Post-Trial Briefs. Permission to use quotation neither sought nor obtained. Emphasis added to quotation. The record in this case convinces me that Singer and Potomac had a divergent interest in achieving quick profits by orchestrating a near-term sale at PLX. […] Singer’s thesis for investing in PLX depended entirely on a short-term sale to the other bidder who emerged during the go-shop period for the IDT transaction. He never prepared any valuation or other analysis of the fundamental value of PLX.”1 No plan or new ideas to improve performance An aggressive focus on short-term value A lack of real analysis or work done to understand KVH’s business or prospects A willingness to subvert the facts and the truth

As its ‘plan,’ Potomac incorporated nearly verbatim its proxy adviser’s generic list of ideas.”4 The court found that the board members breached their fiduciary duties as a result of various process and disclosure deficiencies to stockholders, many of which were due to Singer having manipulated the sale process and Singer and the company’s financial advisor having withheld information from the other board members.”3 …[T]he court held that the activist fund, acting through its co-manager Singer, had knowingly participated in—indeed caused—the directors’ breaches of duty by withholding material information from the board and by working to engineer the sale that he had wanted from the outset.”2 November 19, 2019 November 19, 2018 March 2019 November 29, 2018

The Court found that Singer, as an agent of Potomac and a director of PLX, faced a classic dual fiduciary problem... The Court… found that Singer’s actions as a director of PLX were geared primarily toward a sale.”3 Singer, and thus Potomac, had knowingly participated in the breach and took steps not only to breach his fiduciary duties, but to induce the rest of the Board to breach its fiduciary duties as well.”2 November 29, 2018 October 17, 2018 January 2019 November 9, 2018

56 Other Companies Have Shared Our Concerns Regarding Mr. Singer and VIEX The Velodyne Lidar Board prides itself on its commitment and adherence to sound corporate governance, seeking highly qualified, independent and diverse directors. The Halls have put forward a candidate in Eric Singer who the Board believes exemplifies none of those characteristics… The Board was, and remains, troubled by Mr. Singer’s history as a public company director, especially as set forth in a Delaware Court of Chancery decision in October 2018. In that case, the Court found that Mr. Singer breached his fiduciary duty as a director of PLX Technology by favoring the interests of one stockholder over the interests of all stockholders.”4 “We do not believe it would be in the best interests of Quantum and its stockholders… to allow VIEX… to control our board and to dictate our business strategy…”3 ”Eric Singer [has:] • No relevant… experience • High turnover in board roles – average board tenure of one year; history as a short-term investor • Five of six companies underperformed against the Russell 3000 Index during Mr. Singer’s board tenure…”2 “The VIEX Group’s ill-conceived theories for how stockholder value can be enhanced at Support.com are thin on facts, substance and viability, reflect no understanding of the support industry…, and are nothing more than a thinly-veiled attempt to further its self- interested agenda…”1 1 Support.com Investor Presentation, (June 8, 2016).

58 Mr. Singer Improved Governance at Quantum… When Required to Do So as Part of a Settlement “Quantum is to change its corporate governance to settle a lawsuit that alleged breaches of fiduciary duty. …[T]he defendants were ex-CFO Fuad Ahmad, ex-CEO Jon Gacek, ex-CEO Adalio Sanchez, and former board members Raghavendra Rau, Alex Pinchev, Clifford Press, Marc Rothman, and activist investor and also board member Eric Singer of VIEX Capital Advisors. The Palkon Action asserted claims against the individual defendants “for breach of fiduciary duty, abuse of control, gross mismanagement, and unjust enrichment”, in 2017-2018… Since this period Quantum has detected mis-filed quarterly and full-year accounts which it is still struggling to correct. As a consequence it was ejected from the NYSE in January 2019.” Quantum Corp Scrubs Up Governance to Fend Off Lawsuit2 • In 2018, a plaintiff brought an action against certain directors and officers of Quantum Corporation, including Mr. Singer • The plaintiff alleged that, during Mr. Singer’s tenure as a director, the Quantum Board and certain senior officers breached their fiduciary duties by causing Quantum to make materially false and misleading statements • As part of an agreement to settle the litigation, Quantum was required to adopt certain corporate governance reforms1, including: - Appointment of a lead independent director - Director term limits - Diversity policy (including the appointment of at least one woman and one member of an underrepresented group) - Compensation clawback policy - Creation of a Disclosure and Controls Committee – consisting entirely of senior officers and no Board members – to assure that all SEC filings are accurate and adhere to proper accounting principles - Revisions to the Company’s Code of Business Conduct and Ethics 1 In re Quantum Corp.

62 We Believe VIEX May Have Disregarded Its 13D Filing Obligations Ownership of VIEX 13D Group Constituents (% of Shares Outstanding)2 Constituents Are Above 5% Threshold Without 13D Disclosure • Section 13(d) of the Exchange Act generally requires a person or group who is the beneficial owner of more than 5% of equity securities to disclose information relevant to that ownership via a Schedule 13D filing • Section 13(d) requirements are intended to help investors make fully informed investment decisions by requiring disclosure of ownership by a person or group that might represent a “potential shift in corporate control”1 • Based on public disclosures of its trading activity, we believe that the VIEX 13D Group constituents crossed the 5% threshold that would require VIEX to file a 13D as early as December 2020; VIEX, however, did not file a 13D until April 2021 • Potomac Capital joined VIEX’s 13D Group3 on May 6 – but neither the 13D reporting the addition of Potomac nor VIEX’s definitive proxy on May 17 discusses Singer’s significant prior relationship with Potomac4 • VIEX is seemingly asking shareholders to believe that VIEX and two frequent collaborators invested and accumulated shares in KVH independently of each other and did not agree to work together until three months after VIEX had nominated directors 1 GAF Corp. v.

Peter Shaper’s Growing Involvement with VIEX Raises Questions 63 January 4, 2021, VIEX delivers its notice of intent to nominate Mr. Mutch and Mr. Singer for election to the KVH Board. This notice does not include any mention of VIEX’s relationship with Mr. Shaper November 2020 through April 2021, the Company holds four more telephone calls with Mr. Shaper; at no time does Mr. Shaper indicate that he intends to work with VIEX, despite the fact that the timing of their engagement with and interest in KVH was almost precisely aligned April 19, 2021, VIEX files an amended 13D indicating that Mr. Shaper had joined its group April 30, 2021, in its first counterproposal to KVH’s settlement proposal, VIEX proposed that Mr. Shaper join our Board and be part of a newly-formed committee aimed at improving financial performance May 1, 2021, in light of a federal bankruptcy judge’s findings that Mr. Shaper had breached his fiduciary duties1, the Company indicated to VIEX that it would not be comfortable adding Mr. Shaper to our Board in a fiduciary capacity November 16, 2020, just ten days after KVH’s first conversation with Mr. Singer, Mr. Shaper arranged for a telephone conversation with the Company to discuss the Company’s business and operations 1 In re Speedcast International Ltd., et al., Ch. 11 Case No. 20-32243 (MI). By Suggesting Mr. Shaper as a Director Candidate, VIEX has Made His Record Highly Relevant to This Campaign

Peter Shaper’s Troubling Record • Mr. Shaper became CEO of Speedcast International, a provider of remote communications and IT services, in February 2020 • Speedcast filed for Chapter 11 bankruptcy in April 2020 while Mr. Shaper was still CEO • In December 2020, Speedcast’s proposed reorganization plan was challenged by Black Diamond, a senior lender to Speedcast • U.S. Bankruptcy Judge Marvin Isgur approved a deal between Centerbridge and Black Diamond • As part of the settlement, Black Diamond was made the sole beneficiary of a litigation trust created under the reorganization to pursue claims against Mr. Shaper for putting his own self-interests ahead of his fiduciary duties 64 1 In re Speedcast International Ltd., et al., Ch. 11 Case No. 20-32243 (MI). Peter Shaper, former CEO of Speedcast International, is the Third Member of the VIEX Group to Have Been Determined by a Court to Have Breached or Aided and Abetted the Breach of His Fiduciary Duty of Loyalty The Context KVH SHAREHOLDERS SHOULD BE SUSPICIOUS OF MR. SHAPER’S INVOLVEMENT IN VIEX’S CAMPAIGN GIVEN THIS SEVERE BLEMISH ON HIS RECORD The Court’s Statements on Peter Shaper There was extensive evidence throughout the case that Mr. Shaper, while serving as a fiduciary to the Debtor and to the Debtor’s predecessor, the entity, repeatedly breached his fiduciary duties and put his personal interests ahead of the company’s interests and refused to give equal treatment to offers that were made that did not work to his personal benefit and made threats to the company of actions that he would take.”1

65 VIEX Rejected KVH’s Attempts to Settle VIEX’s Counteroffer: VIEX’s Counteroffer: VIEX’s Counteroffer: • Engage Peter Shaper as a consultant • VIEX to participate in the announcement of two new, diverse nominees • Stan Honey to stand for re-election at Annual Meeting • No standstill, voting or other restrictions on VIEX • Due to Mr. Shaper’s fiduciary duty issues, KVH would not be comfortable appointing Mr. Shaper to our Board, but it would engage him as a consultant • Mr. Honey would stand for re-election but would not serve another term • No standstill, voting or other restrictions on VIEX • Mr. Shaper would be retained as a consultant and invited to present to our Board • Mr. Honey would not stand for re-election • VIEX to participate in the announcement of two new, diverse nominees • Board would form a committee focused on improving financial performance • Mr. Shaper joins our Board • Board forms a new committee focusing on improving financial performance • Mr. Honey does not stand for re-election • A close VIEX associate, Bradley Radoff, joins our Board • A close VIEX associate, Bradley Radoff, joins our Board KVH’s Offer #1 (April 30) KVH’s Offer #2 (May 1) KVH’s Offer #3 (May 2) KVH WAS WILLING TO ACCEPT TWO OF THE THREE KEY TERMS OF VIEX’S FIRST COUNTEROFFER, BUT OUR BOARD WOULD NOT ACCEPT A DIRECTOR WITH FIDUCIARY DUTY ISSUES OR CLOSE TIES TO VIEX We Made Several Reasonable Offers to VIEX to Avoid a Proxy Contest, but VIEX Refused to Resolve This Election Contest

Rebutting VIEX’s Claims

68 VIEX’s Claims Are False VIEX’S CLAIM REALITY “[W]e embrace and welcome the addition of two new, diverse candidates…”1 • VIEX has only publicly nominated one woman in its entire history, which includes 37 public nominations • Only one woman (Mary Dotz) serves on Mr. Singer’s two current public company boards2 “…KVHI’s stockholder value has historically underperformed its peers…”1 • We have outperformed the medians of our industry peers, our compensation peers and our ISS peers year-to-date and over one, two and five years3 “Our director candidates… have a clear vision for working collaboratively with the other Board members…”1 • To date, VIEX has not provided any “vision”, or even any new ideas for what KVH should do differently to improve performance • Mr. Singer has a history of threatening and intimidating behavior towards his fellow directors • One of his former colleagues from the PLX Technology board described Mr. Singer as “combative and a bully”4 • Refused to meet with KVH Board members 1 VIEX Definitive Proxy Statement, (May 17, 2021). 2 Mary Dotz is the only woman on the boards of both A10 Networks and Immersion. 3 Source: FactSet.

VIEX’s Claims Are False, Continued VIEX’S CLAIM REALITY “[I]t is integral to add a stockholder to the Board…”1 • KVH already has substantial shareholder representation on our Board • Mr. Tavares serves on our Board as an appointee of Vintage Capital Management, the Company’s second-largest shareholder • Mr. Kits van Heyningen beneficially owns more than 6% of KVH’s outstanding shares and is one of the Company’s largest shareholders • As a group, KVH’s current directors own substantially more stock than VIEX and Mr. Mutch combined “The Investor Group believes that Board refreshment is long overdue, and an infusion of directors who have strong track records of holding management teams accountable to drive greater value should be added to the Board.”2 • With the addition of our two new director nominees, four of the Company’s six independent directors will have joined the Board in the past two years • Further, of the 12 public company boards Eric Singer has served on in the last ten years, every one underperformed the S&P 500 and Russell 3000 during his tenure.3 That is not a “strong track record” of “driv(ing) greater value.”1

Conclusion

Should VIEX Capital – which first invested in KVH roughly six months ago and has not put forward even a single suggestion for improving the Company – be able to substitute a director with a troubling past and his close colleague for two exceptional, new directors? 71 The Question for Shareholders

72 Conclusion • Our positive momentum – as evidenced by recent outperformance of peers and strong first quarter results – is sustainable and will be bolstered by our ability to be a disruptor in large, growing markets • The Company has been working towards a shift to more recurring revenue and CaaS products – a transition that has already begun paying off and has positioned KVH to boost profitability and shareholder returns over the mid-term • We still have significant work to do in order to ensure we meet these goals and can steadily increase profitability. But we are confident we are on the right path KVH’s Strategy is working • Cielo Hernandez and Cathy-Ann Martine- Dolecki are fully independent and possess the deep global telecommunications, commercial maritime and financial and executive leadership to be able to help the Company • They will also enhance Board diversity and will bring our average independent director tenure to less than five years • We have embraced board refreshment and working constructively with our shareholders – ultimately our only goal is to put the best people in the boardroom to help us succeed We have the right nominees • VIEX and its group have run a campaign devoid of ideas to improve our business or enhance sustainable returns • The track records of the VIEX nominees and group members are highly relevant to the choice before shareholders – and so is the fact that Mr. Singer, Mr. Shaper and Potomac Capital have all been found by courts of law to have breached or aided and abetted the breach of fiduciary duties • When compared against our independent and diverse nominees with relevant industry experience, the VIEX candidates simply do not measure up VIEX’s nominees are the wrong choice

78 Non-GAAP Information This presentation includes a range for KVH’s estimated Adjusted EBITDA margin over the mid-term. Adjusted EBITDA margin represents Adjusted EBITDA for a period divided by revenue for that period. Adjusted EBITDA represents net income or loss, calculated in accordance with GAAP, adjusted to exclude the following items, to the extent applicable: income tax (benefit) expense; interest (income), net depreciation and amortization; stock-based compensation expense; goodwill impairment losses; intangible asset impairment losses; non-recurring inventory reserve; transaction-related and other non-recurring legal fees; other non-recurring costs; and foreign exchange transaction loss. Forward-looking quantitative information for KVH’s net income or loss, the financial measure calculated in accordance with GAAP that is most directly comparable to Adjusted EBITDA, is not available because KVH cannot predict future amounts of the items excluded from net income or loss in the calculation of Adjusted EBITDA without unreasonable effort. These items depend on many factors, can be highly variable and can be significant in relation to net income or loss. This information should not be considered in isolation or as a substitute for financial information prepared in accordance with GAAP. KVH generally uses Adjusted EBITDA and/or Adjusted EBITDA margin to facilitate financial and operational decision-making, including evaluation of historical operating results, comparison to competitors’ operating results, and determination of management incentive compensation. KVH believes that these measures, when viewed with GAAP results, may provide a more complete understanding of factors and trends affecting its business.

79 Proxy Peer Group Overview Our Board developed our Proxy Peer Group in consultation with Aon as part of the Board’s executive compensation review. We have referred to this list in our proxy statement1 previously, although we have only noted that we use it for compensation benchmarking purposes; we have not explicitly used it to compare performance. Our Proxy Peer Group initially focused on a group of 21 companies in adjacent GICS sub-industries (including Communications Equipment, Aerospace & Defense and Technology Hardware) and of similar size in terms of market capitalization and revenue. We have removed two of the peers that were in the initial list, Perceptron and Telenav, because they are no longer publicly traded. When this list was initially formulated, it placed KVH near the median in terms of number of employees, revenue, and market capitalization. Using current data, KVH is in approximately the same position, as shown in the chart to the right. 1 KVH 2020 Proxy Statement at Page 20 (April 29, 2020). 2 Source: FactSet. Data as of May 26, 2021.

80 ISS Peer Group Overview The ISS Peer Group was used in KVH’s 2020 ISS report. The ISS peer group methodology “focuses on identifying companies that are roughly similar to the subject company in terms of industry profile, size and market capitalization.”1 ISS peer groups generally contain a minimum of 12 and a maximum of 24 companies based on GICS classification and size constraints with respect to revenue and market cap. The ISS Peer Group referenced in this Investor Presentation excludes Arotech Corporation, which is no longer publicly traded.

81 Public Satellite/Communications Peer Group Overview Our Public Satellite/Communications Peer Group is comprised of the non-inertial navigation competitors and suppliers as listed in KVH’s 2020 10-K.1 We use this list on page 15 of this Investor Presentation specifically to highlight the fact that conditions in our industry have been challenging over the last several years – particularly during the pandemic. We do not use this list to compare performance over other time periods for three primary reasons: • Most of these companies are significantly larger than KVH; some are as much as 10x the size of KVH in terms of revenue or market capitalization; • A number of these companies are either in bankruptcy2 or are otherwise no longer public,3 so, a) their stock prices have been extremely volatile, or b) they may not have recent trading data, so to use these companies as a benchmark to compare near- term performance would be somewhat misleading; and • There is a limited number of these competitors, so due to the small sample size, the anomalous performance of one peer can distort the results significantly. 1 KVH 2020 Form 10-K at Page 13 (March 3, 2021). 2 E.g., Global Eagle and Speedcast International. 3 E.g., Inmarsat. 4 Source: FactSet.
