Shakespeare's work undoubtedly formed the great bulk of the company's repertory. In their first year of performance, they may have staged such of Shakespeare's older plays as remained in the author's possession, including "Henry VI, Part 2", "Henry VI, Part 3", as well as "Titus Andronicus". "A Midsummer Night's Dream" may have been the first play Shakespeare wrote for the new company; it was followed over the next two years by a concentrated burst of creativity that resulted in "Romeo and Juliet", "Love's Labours Lost", "The Merchant of Venice", and the plays in the so-called second tetralogy. The extent and nature of the non-Shakespearean repertory in the first is not known; plays such as "Locrine", "The Troublesome Reign of King John", and Christopher Marlowe's "Edward II" have somewhat cautiously been advanced as likely candidates. The earliest non-Shakespearean play known to have been performed by the company is Ben Jonson's "Every Man in His Humour", which was produced in the middle of 1598; they also staged the thematic sequel, "Every Man Out of His Humour", the next year.
