As disclosed in our Current Report on Form 8-K filed with the Securities & Exchange Commission (the “SEC”) on August 15, 2025, on August 13, 2025, North Carolina Chief Business Court Judge Michael L. Robinson entered an Order directing the Company to hold its Annual Meeting on Monday October 13, 2025 (the “Order”). The only matter to be considered and put to a vote of shareholders at the Annual Meeting shall be election of the members of the Company’s Board of Directors. According to the Order, for purposes of this Annual Meeting only, the number of shares represented by shareholders who appear at the Annual Meeting, in person or by proxy, will represent a quorum. Therefore, your vote could be very important.

As noted above, the purpose of the meeting is to elect five nominees to the Board of Directors. The Company’s director nominees consist of existing directors Ruten Bhanderi, Anne M. Butler, Neal Goldman, Don O’Connell and James Tu. RiverStyx Fund, LP, which (according to its Schedule 13D/A filed with the SEC on September 2, 2025) beneficially owns approximately 5.19% of the Company’s outstanding common stock, has nominated Ben Franklin, Michael R. Levin and Lloyd M. Sems, and Duc Pham, who (according to his Schedule 13D filed with the SEC on August 27, 2025) beneficially owns approximately 6.71% of our outstanding common stock, has nominated himself.

Our stock transfer books will not be closed. A list of the shareholders entitled to vote at the Annual Meeting may be examined at our principal executive office at 170 Southport Drive, Morrisville, North Carolina 27560 during ordinary business hours beginning two business days after the date this notice of the Annual Meeting is mailed through the date of the Annual Meeting for any purposes related to the meeting. The Board of Directors has fixed the close of business on August 29, 2025 as the record date for the determination of shareholders entitled to vote at the meeting and any adjournments or postponements thereof, provided that our Board of Directors may fix a new record date for an adjourned meeting. Accordingly, only shareholders who are holders of record at the close of business on that date are entitled to notice of and to vote at the meeting.

By order of the Board of Directors,
