Based on an analysis of Form 144 and Form 4 filings, the possible motivations for the insider stock sale include:

The Form 144 filing clearly states the reason for the sale as “

” [1]. Specifically:

• Stock Option Exercise
  : Westbrooks exercised two types of non-qualified stock options on January 14, 2026:
  • 5,172 shares with an exercise price of $12.45 (expiring March 1, 2019)
  • 1,760 shares with an exercise price of $14.34 (expiring September 24, 2018)
• Restricted Stock Vesting
  : Part of the sale comes from the vesting of restricted stock
• This is a
  routine compensation realization act
  , not a negative judgment on the company’s prospects

From the perspective of market timing:

• MTUS’s stock price reached a
  52-week high
  on January 8, 2026 [4]
• The stock price has risen by
  38.69%
  over the past year, and as much as
  267.96%
  over the past five years [5]
• The insider’s choice to sell near an all-time high is a
  rational profit-locking action
• This reflects the insider’s recognition of the current valuation, rather than concerns about the future

• Stock accounts for a high proportion of executive compensation, requiring appropriate
  investment portfolio diversification
• Part of the sale may involve
  estate planning or family financial arrangements
• This aligns with the routine needs of executive personal wealth management

• Option exercise involves
  tax liabilities
  , and selling some shares to pay taxes is a common practice
• Conducting tax-planning sales at the end or beginning of the year is standard practice
• The 10b5-1 plan established on May 12, 2025, may include tax optimization considerations [1]

• There is no evidence that the executive is facing personal financial pressure
• The scale of the sale is small relative to the shareholding ratio (Westbrooks only reduced his holdings by 5.47%) [1]
• This falls within the scope of normal financial planning

• Continuous Insider Sales
  : No insider purchases in the past year [3]
• Multiple Executives Participating in Sales
  : The CEO and COO reduced their holdings simultaneously
• Timing of Sale
  : Conducted at a stock price high, which may reflect concerns about valuation bubbles

• 10b5-1 Plan Transaction
  : Executed via a pre-set trading plan under Rule 10b5-1, indicating the sale was
  pre-planned
  rather than an impulsive decision [1]
• Retaining a Large Number of Shares
  : Westbrooks still holds 189,076 shares after the sale, and Williams still holds 697,373 shares [2]
• Not a Dump
  : The share reduction ratio is relatively moderate, not a large-scale liquidation
