## About

Formed in 1985 alongside the creation of the holding company itself, the Pinnacle West Capital Corporation Retirement Plan serves as the primary defined-benefit vehicle for employees of Arizona Public Service (APS) and other Pinnacle West subsidiaries. The plan is a legacy pension structure within a vertically integrated electric utility that generates and distributes power across Arizona. Unlike a sovereign or endowment that chases absolute return, this plan's investment function is a back-office utility — designed to defease future benefit obligations quietly and predictably. Asset allocation leans defensive. The plan maintains a direct commercial real estate portfolio, the Pinnacle West Retirement Plan Real Estate Portfolio, alongside a stable value fund. These are classic rate-regulated-utility pension allocations — tangible assets and capital-preservation wrappers — rather than heavy tilts to venture or private equity. APS operates within the Arizona Corporation Commission's rate framework, which tends to favor steady, recoverable cost structures in both operations and employee benefits. Geographic exposure is concentrated in the US Southwest, with real estate assets held domestically. The plan does not disclose total assets under management. Public filings from Pinnacle West Capital offer incomplete segmentation of pension assets versus corporate treasury holdings. The plan's governance runs through the corporate executive team; Jeffrey Guldner, as CEO, and Kathryn Munro, as Lead Director, ultimately sit atop the fiduciary chain. A related philanthropic vehicleis maintained separately. This is not a fund that competes for deals. It is a closed, single-sponsor pension pool. Its structural differentiator is the sponsor itself — a regulated electric monopoly whose steady revenue provides a natural hedge against the kind of funded-status volatility that can plague multi-employer or variable-contribution plans. For an external manager, the door is through the plan's consultants or through relationship-building with the corporate treasury group, not through public pitch processes.

## Questions

### Is the Pinnacle West retirement plan open to co-investment or outside partnerships?

The plan is a single-sponsor defined-benefit pool, not a commingled fund open to third-party investors. External managers can access it by working through the plan's investment consultants or by engaging the corporate treasury and finance leadership at Pinnacle West Capital.

### Does the plan disclose its total assets?

No. Pinnacle West Capital Corporation's public filings do not separately report the retirement plan's total assets in a granular, consistently updated format. The plan remains effectively undisclosed in scale, placing it among the quieter public-company pension pools.

### What role does the Arizona Corporation Commission play in the plan's funding?

The Commission regulates APS's rates, which directly influence the utility's revenue and, by extension, its ability to make employer contributions to the pension plan. Rate cases can impact the pace and certainty of plan funding, making the regulatory calendar a material factor for any long-duration liability analysis.
