Simulations Plus Inc. (NASDAQ: SLP) saw its stock price plummet by 6.42% on October 24, 2024, following the release of its fiscal year 2024 earnings report. The company reported impressive revenue growth of 18% year-over-year, reaching $70 million, driven by strong performance in both its software and services segments. However, investors appeared to be concerned about certain factors that overshadowed the positive top-line growth.

One of the key issues highlighted in the earnings report was the decline in gross margin, which fell to 62% for the fiscal year. This was primarily attributed to the reclassification of operating expenses and additional costs related to the company's recent acquisitions, including the integration of Pro-ficiency, its largest acquisition to date.

Furthermore, the contribution from Pro-ficiency in the fourth quarter was lower than expected, impacted by project timing delays and recognition issues. This raised concerns among investors about the potential challenges in fully realizing the synergies and growth opportunities from the acquisition.
