Good day, ladies and gentlemen. Welcome to the Sempra first quarter earnings call. Today's conference is being recorded. At this time, I'd like to turn the conference over to Mr.

Donovan. Please go ahead.

Glen Donovan -- Vice President, Investor Relations

Good morning, everyone, and welcome to Sempra's first quarter 2022 earnings call. A live webcast of this teleconference and slide presentation is available on our website under the investors section. We have several members of our management team with us today, including Jeff Martin, chairman and chief executive officer; Trevor Mihalik, executive vice president and chief financial officer; Lisa Alexander, senior vice president, corporate affairs, and chief sustainability officer; Justin Bird, chief executive officer of Sempra Infrastructure; Faisel Khan, senior vice president and chief financial officer of Sempra Infrastructure; Allen Nye, chief executive officer of Oncor; Kevin Sagara, executive vice president and group president; and Peter Wall, senior vice president, controller, and chief accounting officer. Before starting, I'd like to remind everyone that we'll be discussing forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.

Actual results may differ materially from those projected in any forward-looking statement we make today. The factors that could cause our actual results to differ materially are discussed in the company's most recent 10-K and 10-Q filed with the SEC. All of the earnings per share amounts in our presentation are shown on a diluted basis, and we'll be discussing certain non-GAAP financial measures. Please refer to the presentation slides that accompany this call for a reconciliation to GAAP measures.

We also encourage you to review our 10-Q for the quarter ended March 31, 2022. I'd also like to mention that the forward-looking statements contained in this presentation speak only of today, May 5, 2022. And it's important to note that the company does not assume any obligation to update or revise any of these forward-looking statements in the future. With that, please turn to Slide 4, and let me hand the call over to Jeff.

Jeff Martin -- Chairman and Chief Executive Officer

Thank you, Glen, and thank you all for joining us today. Against the backdrop of a challenging economic environment, our company remains focused on executing our T&D investment strategy in our core markets. Sempra California is preparing to submit GRC filings at both SDG&E and SoCalGas later this month, focused on providing safe, reliable and cleaner energy to its 26 million consumers. Turning to Texas, Oncor is executing on its record five-year capital plan focused on critical T&D infrastructure investments across its service territory to support strong demographic growth and plans to file its rate case later this month.
