  • Hedging/pledging: Company policy prohibits directors and employees from pledging company securities or engaging in hedging/derivatives (e.g., collars, swaps) on company stock .

Governance Assessment

  • Independence and engagement: Teamey is affirmed independent under NYSE rules and met the ≥75% attendance threshold in 2024, signaling baseline governance effectiveness. Board and committee activity levels (17 board meetings; Audit 5, Comp 3, N&G 4) indicate a material governance workload .
  • Committee influence: As a member of Compensation and Nominating & Governance, Teamey participates in executive pay oversight, clawback policy administration, succession planning, board composition and independence reviews—core levers for governance quality .
  • Pay alignment: Director pay mix skews to equity; Teamey’s 2024 compensation was ~72% equity ($158,237 stock awards) and ~28% cash ($62,500). In 2025, the board agreed to forego cash retainers, increasing alignment but also reflecting liquidity discipline amid capital needs .
  • Ownership and skin-in-the-game: Teamey beneficially owns 11,714 shares (<1%) and had 13,513 RSUs outstanding at year-end 2024—meaningful but not large; policy restrictions on pledging/hedging support alignment .
  • Conflicts/related parties: No Teamey-specific related-party transactions disclosed. Company-level related-party dynamics include SBE/Honeywell commercial and financing arrangements and bridge notes with warrants issued to “certain directors and members of management,” without naming participants. Audit Committee oversees related-party reviews under the policy; continuing vigilance is warranted (particularly around financing structures and asset sale-leaseback with Honeywell’s affiliate) .
  • Board structure: Non-executive Chair also serves as lead independent director, with all directors independent—this concentrates leadership oversight but maintains an independent board profile under NYSE standards .

Potential RED FLAGS to monitor

  • Related-party financing and commercial arrangements (e.g., Honeywell investments/warrants, UOP supply/leaseback; bridge notes with director participation) create appearance risks requiring robust Audit Committee oversight and transparent disclosure .
  • Capital structure actions (standby equity purchase agreement; potential dilution scenarios) underline the importance of strong governance around financing decisions; board members on Compensation and N&G (including Teamey) should ensure alignment and investor communication quality .
