Shares of Groupon jumped 10.2% to $21.02 after shareholder Nick Nemeth published an open letter demanding the board accelerate stock repurchases, set a $120 million operating cash floor, and adopt a so-called Rule 10b5-1 plan — a pre-set buying schedule that lets companies repurchase shares even during earnings blackout periods when executives can't trade. Nemeth publicly called on the board and management to take all three steps today. The rally was amplified by a favorable macro backdrop as Treasury yields and oil prices eased.

  • A 78,000-Share Investor Is Punching Above His Weight. Nemeth holds a position representing 78,200 Groupon shares and share equivalents, plus additional call options — a tiny fraction of the company's 40.67 million shares outstanding. Yet the stock's reaction signals that the market already agrees with the thesis. FINRA reported 14 million shares sold short as of July 31, representing 36.15% of outstanding shares, meaning aggressive buybacks could force short sellers to cover, creating a self-reinforcing price squeeze.

  • There's Real Money on the Table — If Groupon Spends It. Cash and equivalents stood at $226.3 million as of June 30. Nemeth wants the board to draw that down to $120 million and deploy the excess into buybacks immediately. He also estimates potential gross proceeds of $180 million or more from selling Groupon's stake in payments firm SumUp within 12 months, though no sale has been announced. Groupon already repurchased 2.8 million shares for roughly $31.4 million in the first half of 2026, so the push is to dramatically scale that pace.

  • The Turnaround Story Is Still Fragile. Q2 2026 loss per share of -$0.04 beat estimates, and adjusted EBITDA hit $14.8 million with $15.0 million in free cash flow — but revenue and billings both declined 1% year-over-year.

Management is targeting 3–5% full-year billings growth and $75–$80 million in adjusted EBITDA, leaning heavily on a second-half reacceleration that has yet to materialize. Spending aggressively on buybacks while the top line is still shrinking is a bet that cost cuts alone can fund shareholder returns.

  • The Math Only Works If Customers Come Back More Often. Nemeth's analysis assumes that raising customer transaction frequency from 2.3 times per year to levels seen at comparable marketplaces could generate roughly $100 million in additional EBITDA per frequency turn. That would transform the economics, but it requires a consumer platform overhaul that Groupon has promised and not yet delivered. For now, the buyback pressure is the catalyst; the frequency story remains the gamble.
