HF Sinclair and PagerDuty Drive This Week’s C-Suite Shake-Up — May 15, 2026

by | May 15, 2026

HF Sinclair (DINO) terminated its CFO and cycled the CEO seat as DINO surges on oil price turmoil. PagerDuty finally makes its move and replaces CEO Jennifer Tejada after years of shareholder losses.

C-Suite Churn Follows Broken Charts

Refining: Termination Beats Tape

HF Sinclair (DINO) put the hard signal at the top of the tape: it terminated CFO Atanas Atanasov effective Feb. 24 and installed Vivek Garg as acting CFO, then Timothy Go exited as CEO and director with Franklin Myers serving temporarily. Shares are no rescue narrative for governance complacency; they are up 94% over one year, leaving the refiner about 67 points ahead of the S&P while it still screens at HIGH activist risk.

HF SINCLAIR CORP (DINO)Energy
$12.4B · 1Y TSR +94.0% · board B · activist HIGH

DINO 5Y stock price

5Y max drawdown: 57.6% (peak 2022-11-21 → trough 2025-03-31)
Atanas Atanasov was terminated as CFO of HF Sinclair, and Vivek Garg was appointed as acting CFO effective February 24, 2026.

Myers, 73, brings 25 years of cumulative public-board service and still sits on Comfort Systems USA (FIX), useful ballast but also a reminder that DINO is leaning on a veteran stopgap. The stock collapsed 58% from its Nov. 21, 2022 peak before rebounding to a 102% five-year gain; five director exits in five years make this more than a finance-department shuffle.

Healthcare: Interim Titles Pile Up

STAAR Surgical (STAA) has collapsed 90% from its Aug. 30, 2021 peak, despite an 84% one-year bounce, and now hands Deborah Andrews the interim co-CEO and CFO stack. The tenure line is ugly: 3 CEOs in 3y · 9 director exits in 5y, which reads less like succession planning than triage.

STAA 5Y stock price

5Y max drawdown: 90.2% (peak 2021-08-30 → trough 2025-02-10)
Deborah Andrews is serving as the Interim Co-Chief Executive Officer and Chief Financial Officer of STAAR Surgical Company.

Doximity (DOCS), down 70% over one year, named Matthew Sonefeldt CFO and Steven Zatz president at a company already on its second CFO in three years. Nektar (NKTR) swapped interim CFO Sandra Gardiner for Linda Rubinstein with a 34-year longest director still on the governance clock.

Software: Chairs Move, Drawdowns Stay

PagerDuty (PD) tapped John DiLullo as CEO and moved Jennifer Tejada to executive chair, a cleaner title but not a clean slate. PD shares have collapsed 88% from their Sept. 13, 2021 peak; Tejada also sits on Estée Lauder (EL), and the board carries a D grade at a company screening HIGH activist risk.

On May 11, 2026, John DiLullo was appointed as CEO of PagerDuty, and Jennifer Tejada transitioned to Executive Chair of the Board of Directors.

C3.ai (AI) brought Thomas Siebel back as CEO and chairman after a 62% one-year stock drop, with Stephen Ehikian shifted to president. SolarEdge (SEDG) is on 3 CFOs in 3y, even after a 180% one-year rebound; the three-year record remains 67 points behind the S&P.

Other Moves To Watch

CEO Transitions

  • Pool Corp (POOL) parted with Peter Arvan by mutual agreement after shares fell 42% over one year, a managed-ouster profile.
  • Simon Property Group (SPG) tapped 38-year-old Eli Simon as CEO and president while shares gained 32% over one year.

CFO Transitions

  • FedEx (FDX) will lose CFO John Dietrich as the logistics giant shows 2 CFOs in 3y and a B- board grade.
  • Progressive (PGR) elected Andrew Quigg CFO as shares slipped 25% over one year, despite an A- board rating.
  • Arteris (AIP) said CFO Nicholas Hawkins will retire after a 397% one-year stock run, making succession a high-class problem.

Board / Director Changes

  • NVIDIA (NVDA) added Suzanne Nora Johnson to the board and Audit Committee while the stock sits 75% higher over five years.
  • TTM Technologies (TTMI) rotated two directors out and two in after a 480% one-year surge, governance refresh without distress.
  • Victoria’s Secret (VSCO) director Mariam Naficy will not stand again after just 72.1% support at last year’s vote.

Beyond the headline
Board Refresh Without Panic
Board refresh was the quieter countercurrent: winners used the tape to add or rotate directors (NVIDIA (NVDA), TTM Technologies (TTMI), Victoria’s Secret (VSCO)).
