(“Peloton”) in the Supreme Court of the State of New York, New York County. The lawsuit arises from a March 2021 Supply Agreement between the parties, pursuant to which MEC was to manufacture and supply custom component parts for Peloton’s exercise bikes (the “Manufacturing Project”). In the lawsuit, the Company originally asserted two claims (1) breach and anticipatory repudiation of contract and (2) breach of the duty of good faith and fair dealing (pleaded in the alternative). In January 2023, in response to Peloton’s motion to dismiss, the court allowed the first claim to proceed and dismissed the alternative claim. In the remaining claim, MEC asserts that Peloton breached and anticipatorily repudiated the Supply Agreement by unilaterally cancelling the Manufacturing Project, and refusing to pay MEC certain monthly fixed revenue payments owed under the terms of the Supply Agreement. The parties have cross-appealed the court’s order on the motion to dismiss – Peloton appealed the portion of the order that denied the motion to dismiss the claim for breach and anticipatory repudiation of contract and MEC appealed the portion of the order that dismissed the claim for breach of duty of good faith and fair dealing. Both appeals are pending. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt 0pt 12pt 0pt;">On November 3, 2023, Peloton filed a counterclaim alleging that Peloton was induced by fraud to enter into the Supply Agreement and seeking recission of the Supply Agreement and damages, among other forms of relief. On November 22, 2023, the Company answered Peloton’s counterclaim, denying the allegations in the counterclaim. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt 0pt 12pt 0pt;">The total amount for damages claimed by MEC is substantial but the amount and timing of the ultimate recovery is uncertain. As a result, any recovery from this litigation or settlement of this claim is a contingent gain and will be recognized if, and when, realized or realizable.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-indent:24.5pt;margin:0pt 0pt 12pt 0pt;">From time to time, the Company may be involved in various claims and lawsuits, both for and against the Company, arising in the normal course of business. Although the results of litigation and claims cannot be predicted with certainty, in management’s opinion, either the likelihood of loss is remote, or any reasonably possible loss associated with the resolution of such proceedings is not expected to have a material adverse impact on the consolidated financial statements.</p>
