WESTLAKE CORP EVP & CFO Mark Steven Bender reported routine equity compensation activity. On May 12, 2026, he exercised 13,164 restricted stock units (RSUs), which converted into the company’s common stock on a one-for-one basis, reflecting the vesting of RSUs granted on May 12, 2023.
On May 13, 2026, 5,284 common shares otherwise issuable were withheld to cover tax obligations arising from this vesting, a non-market, tax-withholding disposition. After these transactions, he beneficially owns 35,895 common shares directly.
Westlake Corporation reported a significantly weaker first quarter of 2026. Net sales fell to $2.65 billion from $2.85 billion, and net loss attributable to the company widened to $169 million, or $(1.31) per share, versus a $40 million loss, or $(0.31) per share, a year earlier.
Gross profit dropped to $112 million with margin halved to 4% from 8%, driven by lower volumes and prices for PVC resin, polyethylene, caustic soda, chlorine and building products, as well as higher fuel costs and a $67 million litigation-related charge. EBITDA declined to $150 million from $288 million.
The Housing and Infrastructure Products segment remained profitable but saw income from operations fall to $56 million from $148 million, while the Performance and Essential Materials segment’s loss from operations deepened to $211 million. Westlake completed the $124 million ACI acquisition, invested $209 million in capital expenditures, used $94 million in operating cash flow, and ended the quarter with $2.27 billion in cash and cash equivalents plus $205 million in available-for-sale securities. It also put in place a new $1.5 billion revolving credit facility and plans to redeem $496 million of 3.60% 2026 senior notes.
Westlake Corporation reported a larger loss but improving trends in first quarter 2026. Net sales were $2.65 billion versus $2.85 billion a year earlier. The company posted a net loss of $169 million, or $1.31 per share, and EBITDA of $150 million.
Results included $85 million of Identified Items, mainly a $67 million PVC pipe litigation settlement and $18 million of shutdown charges. Excluding these items, net loss was $100 million, or $0.77 per share, and EBITDA was $235 million.
Housing and Infrastructure Products generated $993 million of sales and $186 million EBITDA excluding Identified Items, with a 19% margin, helped by strong pipe and fittings demand from infrastructure spending. Performance and Essential Materials delivered $1.66 billion of sales and $36 million EBITDA excluding Identified Items.
Westlake ended March 31, 2026 with $2.5 billion in cash, cash equivalents and fixed‑income investments and $5.6 billion of total debt. Management targets a $600 million EBITDA uplift in 2026 from footprint optimization, cost savings and reliability, and now expects the HIP segment’s 2026 revenue and margin at the lower end of previously communicated ranges.

Westlake Corp senior vice president Brian John Powers reported a compensation-related equity award of 1,961 restricted stock units (RSUs), each representing a contingent right to receive one share of Westlake common stock. All of these RSUs are scheduled to vest on April 2, 2029.
This filing reflects a grant/award acquisition rather than an open-market stock purchase or sale, and leaves Powers with a reported total of 1,961 RSUs following the transaction.
Westlake Corporation entered into a new unsecured revolving credit agreement with a syndicate of lenders, providing a senior revolving credit facility of up to $1.5 billion. This new facility replaces Westlake’s prior $1.5 billion revolving credit facility, which was terminated without costs or penalties.
Borrowings may bear interest at a Term SOFR-based rate plus a margin ranging from 1.000% to 1.625%, or at an ABR-based rate plus a margin ranging from 0.000% to 0.625%, in each case depending on Westlake’s credit rating. An undrawn commitment fee between 0.090% and 0.200% also applies based on credit ratings.
The facility, which matures on April 2, 2031, includes a $150 million sub-limit for letters of credit and a discretionary $50 million swingline loan commitment available on a same-day basis. Westlake may, subject to conditions and lender agreement, increase the facility size by up to $500 million in increments of at least $25 million. The agreement includes customary covenants, a quarterly total leverage ratio maintenance test, and standard events of default that can trigger accelerated repayment and higher default interest on overdue amounts.
Westlake Corp senior vice president Brian John Powers filed an initial ownership report showing equity-based compensation in the form of restricted stock units and stock options tied to common stock. He holds RSUs for 5,645 and 882 underlying shares that vest between 2028 and 2030, plus 3,233 stock options at $94.48 per share expiring in 2036, vesting in three annual installments starting in 2027.
