       Management Discussion and Analysis of Financial Condition and Results of 
Operations
       Results of Operations, page 34

   1.                                                   Please expand your 
discussion of your result of operations to provide a more
                                                        comprehensive and 
quantified discussion and analysis of the factors that impacted your
                                                        results between 
comparative periods. Revise your future annual and quarterly filings to
                                                        provide the following 
items.
                                                            Expand your 
discussion of net sales to quantify how much of the decrease in net sales
                                                            was due to changes 
in volume and product mix and the reasons for these changes as
                                                            well as changes in 
weighted average sales price. Given your decrease in net sales of
                                                            $338.8 million or 
16.9% for the year ended December 31, 2023, revise your
                                                            disclosure to help 
us understand how growth in higher-margin end markets have
                                                            enabled you to 
increase your net sales and margins for the period. We note your gross
                                                            profit margin for 
the years ended December 31, 2023 and 2022, were 39.6% and
                                                            41.3%, 
respectively.
                                                            You disclosed that 
you were in the midst of a current supply-constrained

              environment. Discuss whether supply chain disruptions materially 
affected your
              outlook or business goals. Specify, whether these challenges have 
materially
              impacted your results of operations or capital resources, and 
quantify, to the extent
              possible, how your net sales, profits, and/or liquidity have been 
impacted. Revise to
              discuss known trends or uncertainties resulting from mitigation 
efforts undertaken, if
              any.
             Expand your discussion of gross profit to discuss and quantify the 
impact of any
              other business factors that affected your gross profit in 
addition to the average unit
              cost increase of 0.2% for the twelve months ended December 31, 
2023. Consider
              discussing the impact of product mix, material pricing, and 
details of other costs that
              impacted your gross profit.
             Enhance your disclosure throughout your MD&A to quantify the 
business reasons for
              the changes between periods in the significant line items of your 
consolidated
              statements of income. For example, selling, general and 
administrative expenses
              decreased by $22.9 million primarily due to lower wages and 
benefits and freight and
              duty costs, partially offset by increases in professional 
services and other selling
              expenses. However, you have not quantified the impact of each 
business reason that
              affected this line item.
             Revise your discussion of other (expense)/income to provide a more 
comprehensive
              and robust discussion of the business reasons materially 
impacting the line times
              within this category, explaining the relative effect of each.
         This is not meant to represent an all-inclusive list of where your 
MD&A could be
         improved. We encourage you to provide quantification of amounts and 
further
         clarification throughout your discussion. Refer to Item 303 of 
Regulation S-K and Section
         III.B.4 of Release No. 33-8350 for guidance.
