The slight increase in the lower end of the forecast range indicates a reduction in expected downside risk, while the minor decrease in the upper end may reflect a more realistic and achievable target. This update could lead to a short-term positive impact on HLIT's stock price as it aligns with the estimated EPS, showing that the company is on track to meet or exceed expectations.
