British defense and aerospace company BAE Systems (BAESY) warned on Wednesday that it might fire as many as 300 workers at its shipyard in San Diego because of a declining workload.

The firings are expected to take place in early September this year.

"We recognize that the workforce reduction will impact our dedicated employees and our shipyard team overall," BAE Systems said in a statement. "We greatly appreciate the contribution and hard work of the employees who will be leaving our organization."

"The workforce action provides the necessary agility to ensure BAE Systems remains in the best position to effectively support the Navy in performing its critical missions," the company added.

Money is just being given away: Warren Buffett donated roughly $3.17 billion of Berkshire Hathaway Inc. (BRK.A - Get Report) (BRK.B - Get Report) stock earlier this week to the Bill and Melinda Gates Foundation and four family charities.

It is the 86-year-old billionaire's largest contribution in his plan to give away his fortune. In 2010, Buffett, Microsoft Corp. (MSFT - Get Report) co-founder Bill Gates and his wife created The Giving Pledge, a project that encourages billionaires to give more than half of their wealth to philanthropy. TheStreet takes a look at some of the wealthiest people who have pledged to give their money to charity when all is said and done.

A return of a bothersome issue for Walmart: Beginning in 2013, reports began circulating that Walmart Stores Inc. (WMT - Get Report) was dealing with an out-of-stock issue at its stores nationwide.

At the time, Walmart attributed the problem to a reduction in employees as it worked to cut costs. Fast forward to 2017, and the issue appears to be resurfacing, reports TheStreet's Lindsay Rittenhouse.

Paypal should cut a big check: It could be time for PayPal (PYPL - Get Report) to get cracking on a bid for fellow payments processor Square SQ , TheStreet reports.

The purchase of Square would give PayPal increased acceptance with bricks and mortar retailers, Loop Capital analyst Joseph Vafi writes in a new note. All in, the deal would further PayPal's efforts to become a "true, two sided network," according to Vafi.

Vafi estimates PayPal would be able to pay a 30% premium for Square, valuing the company at more than $12 billion using current prices.

Tesla gets some more love: Shark Tank Star Kevin O'Leary said Tesla (TSLA - Get Report) CEO Elon Musk is a modern day Michelangelo. "He is a genius - I can't say enough good things about what he does for all sectors that he gets involved in," O'Leary told TheStreet's Scott Gamm in an interview.

Although to be fair, O'Leary is more fond of Tesla's product than its stock.

"I'm an investor and at the end of the day, I look at each opportunity to put money in harms way - one stock at a time and that's not a stock I own," he said. O'Leary is also the Chairman of O'Shares ETF Investments.
