Winchester Bancorp Reports FY2026 Results; Changes Fiscal Year End

What Happened

• On July 30, 2026, Winchester Bancorp, Inc. (holding company for Winchester Savings Bank) issued a press release reporting its financial results for the year ended June 30, 2026; the press release is included as Exhibit 99.1 to the Form 8-K.
• On July 29, 2026, the Board approved changing the Company’s fiscal year end from June 30 to December 31. The bylaws were amended (Article VI, Section 5) to reflect the new fiscal year; the amendment is filed as Exhibit 3.2.

Key Details

• Press release announcing results dated July 30, 2026 (Exhibit 99.1).
• Fiscal year-end change approved July 29, 2026; new fiscal year will end December 31.
• Company will file a transition Form 10-K covering the six‑month period July 1–December 31, 2026.
• The Company expects to file a Form 10-Q for the quarter ending September 30, 2026, then quarterly reports aligned to the new fiscal year beginning with the quarter ending March 31, 2027.

Why It Matters

• The fiscal year change alters the company’s reporting calendar and creates a six‑month transition period; investors should note this when comparing year‑over‑year earnings, revenue and quarterly results.
• Expect a transition Form 10-K (six months) rather than a standard 12‑month annual report for FY2026, and timing of future quarters will shift to a calendar-year basis starting in 2027.
• Investors should review the July 30 press release (Exhibit 99.1) and monitor the upcoming transition 10-K and September 2026 10-Q for full financial details and any impact on periodic results.
