Are there any recent large contract wins, renewals, or platform upgrades that drove the ARR increase?

Based on the information contained in the news release you provided, FalconStor Software highlighted the overall strategic shift to subscription‑ and consumption‑based recurring‑revenue models as the primary driver of the 57 % year‑over‑year increase in its hybrid‑cloud ARR (annualized recurring revenue) run‑rate for Q2 2025. The release quotes CEO Todd Brooks saying:

“Our strategic shift to subscription and consumption‑based recurring revenue models continued in Q2, with hybrid cloud ARR run‑rate increasing 57% year‑over‑year.”

However, the announcement does not specify any particular large contract wins, renewal events, or platform‑upgrade projects that directly contributed to that ARR growth. No new customer deals, extensions of existing contracts, or major product‑upgrade initiatives are mentioned in the excerpt you shared.

Bottom line

• No explicit large contract wins, renewals, or platform upgrades are identified in the provided news release as the source of the ARR increase.
• The ARR growth is attributed generally to the company’s ongoing transition to a subscription/consumption revenue model and the resulting higher hybrid‑cloud recurring‑revenue base.

If you need details on specific deals or upgrades that may have under‑pinned the ARR rise, you would likely have to look for additional communications (e.g., a more detailed earnings call transcript, a press release on a particular customer win, or a follow‑up filing with the SEC) that were not included in the excerpt you posted.
