[12] The team was returned to the league in 2019 with Kim Pegula quoted as saying “Our main goal has always been fostering the growth of women’s hockey across all ages.” “We thank our Beauts players, staff, and fans for their support this past season.

We will continue to look for ways to successfully grow the women’s game.”[13] In 2018, Pegula Sports & Entertainment reached an agreement to purchase the intellectual property of the Rochester Knighthawks of the National Lacrosse League in autumn 2019.

Rochester Sports Group owner Curt Styres orchestrated the sale as he planned on moving his staff and roster to a new Halifax NLL team set to debut in the winter of 2020; the NLL does not have restrictions on ownership groups owning multiple teams (as it is, the Bandits are owned primarily by Terry, while Kim, who grew up in Rochester, will have a larger role in operations over the Knighthawks).

PSE also owned PicSix Creative which serves as the company's in-house marketing, design, production and communications services firm.

[16] The company was the owner and operator of LECOM Harborcenter, a $250 million hockey-themed building, which is anchored by the two rinks, a large parking garage, retail, and restaurants including a Sabres themed Tim Hortons and a Marriott hotel.

[17][18] On September 10, 2019, Pegula Sports and Entertainment reached a 10-year naming rights agreement for the building with Lake Erie College of Osteopathic Medicine (LECOM).

[26] On April 25, 2017, it was announced that Labatt USA and PSE had partnered on a project to develop the Pegula owned 79 Perry Street in the Cobblestone district in Buffalo into a mixed use facility to include a small test brewery called the "Labatt House", a restaurant called "The Draft Room" as well as retail, commercial and residential space.

[33] The company also owned Deer Valley Trails in the Adirondack Mountains town of St. Regis Falls, New York and Terra Mare, a restaurant in Fort Lauderdale, Florida.

[34][35] The company holds a marketing partnership with Sear, a Buffalo steakhouse co-owned by Bills alumni Fred Jackson, Terrence McGee and Brian Moorman.

[38] Through a partnership with Southern Tier Brewing Company, PSE launched a "One Buffalo" branded craft beer that sells at all Pegula-owned properties and elsewhere in the region.

[39] The One Buffalo brand has also been extended to a flavor of Perry's Ice Cream and premium cupcakes, both formulated by Kim Pegula, a pronounced fan of desserts.

This was followed by the departure of several other high-ranking executives over the course of the next year; Michael Gilbert and Nik Fattey left in December 2018, and Bruce Popko (chief operating officer, who after Brandon's departure was the highest ranking person in the organization who was not a member of the Pegula family), Brent Rossi (chief administrative officer who had replaced Gilbert), and Erica Muehlman (a senior vice president) were all fired in February 2019, with Kim Pegula indicating none of the positions would initially be replaced.

[42] In April 2020, during the COVID-19 pandemic in New York (state), an article from The Athletic by Tim Graham detailed and criticized PSE's termination of numerous employees in what was seen as a cost-saving measure, and also described "low morale" and a "toxic culture" within the Sabres and across the whole organization.
