FIORAVANTI, Vice Chancellor Two co-founders of a Delaware corporation collectively held a majority of the

corporation’s voting power. They later executed an irrevocable proxy and power of

attorney and, at the same time, entered into a separate voting agreement. The proxy

gave one co-founder the right to vote the other’s shares for two years. By contrast,

the voting agreement gives the same co-founder the right to direct the vote of the

other’s shares and specifies that it terminates only upon the parties’ mutual

agreement.

This post-trial decision resolves a dispute over the validity and duration of the

voting agreement. The co-founder who surrendered his voting rights contends that,

like the proxy agreement, the voting agreement terminates after two years.

Alternatively, he seeks reformation for mistake or a declaration that the voting

agreement is unenforceable due to lack of consideration, fraudulent inducement, and

ethical violations by the other co-founder’s counsel. The other co-founder concedes

that the proxy agreement expired after two years but maintains that the voting

agreement is effective until both parties agree to terminate it.

The court concludes that the parties entered into a valid voting agreement

supported by consideration, that they manifested mutual assent to that agreement,

and that there was neither mutual nor unilateral mistake. The court also concludes

that there was no fraudulent inducement and that any alleged violations of the rules

of professional conduct have no bearing on the validity or enforceability of the agreement. The court further concludes that the voting agreement’s unambiguous

termination provision requires mutual agreement of the parties. Therefore, judgment

will be entered in favor of the defendant.

I. BACKGROUND These are the facts as the court finds them after trial.1

1 Other factual findings are contained in the analysis of the claims. Deposition testimony is cited as “(Surname) Dep.”; trial exhibits are cited as “JX”; stipulated facts in the pre- trial order are cited as “PTO”; and references to the docket are cited as “Dkt.,” with each followed by docket number and the relevant section, page, paragraph, or exhibit. Citations to testimony presented at trial are in the form “Tr. # (X),” with “X” representing the name or surname of the speaker. Citations to the transcript of post-trial oral argument, Dkt. 196, are in the form of “Post-Trial Arg.” After being identified initially, individuals are referenced herein by their names or surnames without regard to honorifics. No disrespect is intended. First names are used herein for clarity and without intending disrespect or familiarity. Unless otherwise indicated, citations to the parties’ briefs are to post-trial briefs. When resolving factual disputes, this decision generally gives more weight to contemporaneous evidence. See Lynch v. Gonzalez, 2020 WL 4381604, at *5 (Del. Ch. July 31, 2020) (“[T]he relative weight given to any particular piece of evidence, and particularly witness testimony, is a matter for the court to determine as the trier of fact.” (citation modified)), aff’d, 253 A.3d 556 (Del. 2021) (TABLE); see, e.g., BCIM Strategic Value Master Fund, LP v. HFF, Inc., 2022 WL 304840, at *2 (Del. Ch. Feb. 2, 2022) (“The witness testimony often conflicted with the contemporaneous record. In resolving factual disputes, this decision generally has given greater weight to the contemporaneous documents.”). Dates and times are indicated in Pacific Time (UTC-7/UTC-8) for consistency, even where events occurred in the People’s Republic of China. The Joint List of Exhibits records the timestamp of the first message in a text thread; subsequent messages may have been sent later. The court identified inaccuracies in certain exhibits’ timestamps and corrected them using other contemporaneous exhibits in the record. Moreover, several of the exhibits are in Chinese. The parties supplied notarized English translations, yet disputes about their accuracy remain. This opinion resolves any divergences through context and close textual analysis of the documents that bear on the disputed language, read against the full record. When necessary to reflect the parties’ disagreement, this opinion presents both versions.
