PROXY STATEMENT

Our Board of Directors is sending you this proxy statement to ask for your vote as a Preformed Line Products Company

shareholder on the matters to be voted on at the annual meeting of shareholders. We will hold the Annual Meeting in

person, on Monday, May 4, 2026, at our Company’s headquarters, 660 Beta Drive, Mayfield Village, Ohio 44143. We ask that

you register your planned in-person attendance with us at least ten business days prior to the meeting, by communicating

with Carrie Vaccariello, by email (carrie.vaccariello@plp.com) or mail (660 Beta Drive, Mayfield Village, OH 44143). In

addition, an admission ticket, as well as matching photo identification, are necessary to gain entrance to the secure area

of our headquarters building where the meeting will be held.

Annual Report. A copy of our Annual Report to Shareholders for the fiscal year ended December 31, 2025 is enclosed with

this proxy statement.

Solicitation of Proxies. Our Board of Directors is making this solicitation of proxies and the Company will pay the cost of the

solicitation. In addition to solicitation of proxies by mail, our employees may solicit proxies by telephone, facsimile or

electronic mail.

Proxies; Revocation of Proxies; Voting Instructions. If you are a shareholder of record, the shares represented by your signed

and returned proxy will be voted in accordance with the instructions as indicated on your proxy. In the absence of any such

instructions, they will be voted (a) to elect the director nominees set forth under “Election of Directors”,(b) to approve, on a

non-binding and advisory basis the compensation of the Company’s Named Executive Officers (or NEOs) and(c) to ratify

the appointment of Ernst & Young LLP ("EY") as our independent registered accounting firm for the fiscal year ending

December 31, 2026. Your presence at the annual meeting of shareholders will not revoke your proxy. However, you may

revoke your proxy at any time before it has been exercised by signing and delivering a later-dated proxy or by giving notice

to us in writing at our address indicated on the attached Notice of Annual Meeting of Shareholders by May 4, 2026, or in the

open meeting.

If you hold shares through an account with a bank or broker, banks and brokers have the authority to vote shares for which

their customers do not provide voting instructions on certain routine matters. The ratification of the appointment of EY as the

Company’s independent registered public accounting firm is considered a routine matter for which banks and brokers may

vote without specific instructions from their customers, but banks and brokers do not have the authority to vote for the

election of directors or on the advisory vote on the compensation paid to the Named Executive Officers. As such, if you own

your shares through a bank or broker and do not provide specific voting instructions to the bank or broker or do not obtain a

proxy to vote those shares, then your shares will not be voted on these matters (“broker non-votes”).

Voting Eligibility. Only shareholders of record at the close of business on the record date, March 5, 2026, are entitled to

receive notice of the annual meeting of shareholders and to vote the common shares that they held on the record date at

the meeting. On the record date, our voting securities outstanding consisted of 4,896,855 common shares, $2 par value,

each of which is entitled to one vote at the meeting.

Quorum. Shareholders, present in person or by proxy and entitled to vote at the meeting, holding shares entitling them to

exercise a majority of the voting power of the Company are necessary to constitute a quorum at the meeting. Abstaining

votes and broker non-votes will be counted as “present” for purposes of determining whether a quorum has been achieved

at the meeting.

Voting Required. The vote required to approve each proposal is as follows:

•Director nominees who receive the greatest number of affirmative votes will be elected directors. Abstentions

and broker non-votes will not be counted in favor of nor against any nominee and, therefore, have no effect

on this proposal.

•Approval of the compensation paid to the NEOs requires the affirmative vote of a majority of the common

shares present in person or by proxy and entitled to vote at the Annual Meeting. Abstentions and broker non-

votes will have the same effect as votes against the proposal.

•Approval of the proposal to ratify the selection of EY as the Company’s independent registered public

accounting firm requires the affirmative vote of a majority of the common shares present in person or by

proxy and entitled to vote at the Annual Meeting. Abstentions will have the same effect as votes against the

proposal. Banks or brokers holding shares for which no voting instructions were received may exercise their

discretionary voting authority for this proposal.

If any other matter properly comes before the meeting, the persons named in the proxy will vote thereon in accordance

with their judgment. We do not know of any other matters that will be presented for action at the meeting and we have not

received any timely notices that any of our shareholders intend to present a proposal at the meeting. If any other matters

are considered at the meeting, they would require for approval the affirmative vote of a majority of the shares entitled to

vote and represented at the meeting in person or by proxy.
