  • Represented the former stockholders of an e-commerce consumer goods transportation company in a case involving the sale of the company to a public transportation company in a four-day Zoom trial in Delaware Court of Chancery. The suit involved the former stockholders’ claim for approximately $60 million plus attorneys’ fees in connection with allegations that the public company breached the earn-out provisions of the sale agreement and violated the covenant of good faith and fair dealing.
  • Obtained a $170 million award after three weeks of evidentiary hearings in an international arbitration on behalf of a global private equity firm that has raised over $18 billion of capital. The arbitration involved claims of fraud and breach of fiduciary duty, and also included over $100 million in counterclaims. In addition to obtaining the award, Mr. Fiotto defeated all counterclaims and also obtained an award of attorneys’ fees.
  • Successfully defended global luxury hospitality company in arbitration involving breach-of-contract claims totaling over $300 million. After a week-long evidentiary hearing, the arbitration panel denied claimant any monetary relief and ordered claimant to pay all of client’s legal fees.
  • Represented a $4 billion venture capital firm in the Delaware Court of Chancery in which the client sought appraisal of the value of its stock in a software company after the company conducted a squeeze-out merger. After a week-long trial, Mr. Fiotto obtained a valuation that awarded our client $23 million, which was over three times the merger price, and was the second highest multiple awarded by the Chancery Court in 30 appraisal decisions over the last decade.
  • In a three-week trial in New York State Supreme Court successfully represented the principals of The Pyramid Companies, a multi-billion dollar commercial real estate firm, in connection with a breach of fiduciary suit brought by a minority partner seeking to dissolve and liquidate one of the Pyramid Companies’ asset-holding general partnerships valued at over $200 million. Mr. Fiotto not only defeated all fiduciary duty claims against the principals, but also obtained a judgment that the minority partner had wrongfully attempted to dissolve the partnership and had thereby forfeited his $5 million partnership interest. Mr. Fiotto also obtained an award of attorneys’ fees. The court in its written opinion cited the “thorough, conscientious and comprehensive representation” by Mr. Fiotto.
  • Represented a $2 billion private equity firm in an arbitration in which the client obtained an approximately $15 million judgment, including an award of the client’s legal fees, after 2 weeks of evidentiary hearings. The case involved claims of fraud and breach of contract, and also involved a multi-million counterclaim against the client, which was dismissed in its entirety.
  • Represented a $1 billion secondary investment firm in a week-long trial in Delaware federal court and successfully defended client against all claims.
  • Represented the owners of a major commercial retail center in a four-week trial in the Business Law Session of the Massachusetts Superior Court as a result of a lawsuit brought by a global retail company. Although the retailer had claimed over $25 million in alleged contract damages, the parties entered into a settlement favorable to Mr. Fiotto’s client after closing arguments and before verdict.
  • Obtained a $32 million judgment on behalf of BayNorth Capital, a Boston-based real estate investment firm, against guarantors in connection with a Utah ski resort.
  • Represented a publicly traded bank with over $10 billion in loan assets in a novel “binding mediation” proceeding against another publicly traded bank. The banks were parties to an indemnification agreement that allocated liability for obligations imposed on our client by prior FDIC Consent Orders, and the indemnifying bank sought a ruling against our client that it was not obligated for nearly $8 million in past obligations and would not be obligated for any future obligations, which potentially involved liabilities valued at many times the past obligations. Mr. Fiotto obtained a binding order from the mediator that established our client’s indemnification rights.
  • Represented in an arbitration an international venture capital firm that had raised over $6 billion in capital in a proceeding in which a former Managing Director brought multi-million dollar claims against the client; on the night before evidentiary hearings were to begin, Mr. Fiotto negotiated an extremely favorable settlement for the client.
  • Obtained a complete dismissal before trial on behalf of investment banking firm, Canaccord Genuity, Inc., of federal securities claims in a nation-wide class action alleging claims in connection with the client’s role as a market maker in several offerings.
  • Mr. Fiotto also regularly represents clients in litigations involving mergers and acquisitions and has in recent years successfully obtained the dismissal before trial of shareholder class actions and/or derivative lawsuits challenging the mergers of Astrazeneka, Inc. and Omthera Pharmaceuticals, Inc.; Dainippon Sumitomo Pharma Co., Ltd. and Sepracor, Inc.; Charlesbank, Inc. and DEI Holdings, Inc.; Perini Corporation and Tutor-Saliba Corporation; Haemonetics, Inc. and Global Med.
