​

We give careful consideration to proposals received from stockholders. Stockholder proposals submitted in accordance with Rule 14a-8 under the Exchange Act are eligible for consideration for inclusion in our proxy statement for the 2027 annual meeting of stockholders if they are received by the company on or before December 29, 2026. In order for a stockholder proposal submitted outside of Rule 14a-8 to be considered at the 2027 annual meeting of stockholders, such proposal must be received by the company not later than the last date for submission of stockholder proposals under the by-laws. In order for a proposal (including nominations of directors) to be timely under the by-laws, it must be received not later than the close of business 90 days (i.e., February 5, 2027) nor earlier than 120 days (i.e., January 6, 2027) before the “Specified Date.” Under the by-laws, the Specified Date is the first Wednesday in May each year (unless it is a legal holiday, in which case the Specified Date is the next day following the Specified Date that is not a legal holiday).

In the event that the 2027 annual meeting of stockholders is called for a date that is prior to the Specified Date, and if less than 105 days’ notice or prior public disclosure of the date of such annual meeting is given or made, notice of any proposal (including nominations of directors) submitted pursuant to the by-laws by a stockholder to be timely must be received not later than the close of business on the tenth day following the earlier of the day on which notice of the

date of such annual meeting is mailed or the day on which public disclosure is made of the date of such annual meeting.

In addition, under Rule 14a-19(b) under the Exchange Act, a stockholder intending to solicit proxies in support of director nominees other than our nominees must provide notice of that intent to us. For our 2027 annual meeting of stockholders, the deadline for providing that notice is currently April 11, 2027. If we change the date of the 2027 annual meeting of stockholders by more than 30 calendar days from the anniversary of the date of our 2026 annual meeting of stockholders, the deadline for the notice under Rule 14a-19 will be the later of 60 calendar days before the date of the 2026 annual meeting or the 10th calendar day after we first publicly announce the date of the 2027 annual meeting of stockholders. The deadline under Rule 14a-19(b) is a minimum notice requirement that does not override or supersede the earlier deadline in our by-laws. A stockholder intending to solicit proxies in support of director nominees other than our nominees must satisfy the requirements of both our by-laws and Rule 14a-19, which imposes conditions beyond those in our by-laws. Rule 14a-19(b) requires that the stockholder’s notice to us must include the names of all nominees for whom the stockholder intends to solicit proxies and must include a statement that the stockholder intends to solicit the holders of shares representing at least 67% of the voting power of shares entitled to vote on the election of directors in support of director nominees other than our nominees.

Annual Report to Shareholders. A copy of our annual report on Form 10-K for fiscal year 2025 as filed with the SEC, together with this proxy statement, is being mailed to stockholders of record as of April 15, 2026. The 2025 Annual Report contains detailed business and financial information about us. The 2025 Annual Report is not incorporated herein and is not deemed a part of this proxy statement.

A copy of our 2025 Annual Report, excluding exhibits, may also be obtained by shareholders without charge by request to KVH Industries, Inc., 500 Wood Street, Unit 320, 1 st Floor, Bristol, RI 02809, Attention: Eileen Pribula or by calling (401) 847-3327 and may be accessed on our website, www.kvh.com.

Eliminating Duplicate Mailings. If you share an address with other KVH stockholders, you may receive notification that you are being sent only a single copy of the proxy materials (including a copy of this proxy statement and the 2025 Annual Report), unless your bank, broker or other intermediary that provides the notification receives contrary instructions from the affected stockholders. This practice, permitted under SEC rules and commonly referred to as “householding,” is designed to reduce expenses associated with proxy solicitations.

If, at any time, you no longer wish to participate in householding and would prefer to receive a separate set of proxy materials, please notify your broker if your shares of common stock are held in a brokerage account or KVH if you hold registered shares of common stock. We will promptly deliver a separate copy of the proxy materials upon request. You can notify KVH by calling (401) 847-3327 or sending a written request to KVH Industries, Inc., 500 Wood Street, Unit 320, 1 st Floor, Bristol, RI 02809, Attention: Eileen Pribula.
